Abstract
The invention relates to a clamping device of a symmetric elbow arm, and the clamping device comprises clamping slide plates which are respectively and movably arranged on two sides of the elbow arm, wherein each clamping slide plate is provided with a clamping seat, the elbow arm is provided with a clamping cylinder, a movable rod of the clamping cylinder is provided with a connection block, the connection block is movably provided with two synchronous rods, one ends of the two synchronous rods are respectively and movably connected with the connection block, and the other end of each synchronous rod is movably connected with the corresponding clamping slide plate. The clamping device is applicable to an elbow machine capable of bending a pipe leftwards and rightwards. By adopting the clamping device of the symmetric elbow arm, the overall structural size of the elbow arm is reduced to the half of the original size, the weight is greatly reduced, the inertia when the pipe is bending is correspondingly reduced, and the pipe bending speed is also increased; and moreover, according to the clamping device of the symmetric elbow arm, the original two drives are changed to a single drive, so that the clamping device is simple in structure, smaller in size, lower in cost and fewer in control points and detection points of the control program.
Description
Technical field
The present invention relates to the technical field of bending machine, refer to especially a kind of clamping device of symmetrical bending pipe arm.
Background technology
Can carry out pipe fitting in the curved bending machine in the left and right sides, it need to clamp respectively two positions of pipe fitting.By adopting two covers to clamp device, be separately positioned on the both sides of bending pipe arm in the present employed bending machine, it is complex structure, bulky not only, and needs to adopt two drivings, and cost is higher.
Summary of the invention
Technical problem to be solved by this invention is: the clamping device that a kind of simple in structure, small volume, lower-cost symmetrical bending pipe arm are provided.
For addressing the above problem, the technical solution used in the present invention is: the clamping device of symmetrical bending pipe arm, comprise the clamping slide plate that is movably arranged on respectively the bending pipe arm both sides, each clamps on the slide plate and is provided with clamping seats, be provided with a clamping cylinder on the bending pipe arm, be provided with coupling block on the motion bar of clamping cylinder, be movably set with two synchronizing bars on the coupling block, one end of two synchronizing bars all is flexibly connected mutually with coupling block, and the other end of each synchronizing bar is flexibly connected mutually with corresponding clamping slide plate.
Each front and back end that clamps slide plate is respectively arranged with front rod and back link, and front rod and back link are arranged in parallel, and an end of front rod and back link is flexibly connected mutually with clamping slide plate, and the other end of front rod and back link and bending pipe arm are flexibly connected.
Described clamping seats is movably arranged on and clamps on the slide plate, clamps on the slide plate and is provided with adjustment seat, is provided with adjustment screw in the adjustment seat, and the end of adjustment screw contacts with clamping seats.
The invention has the beneficial effects as follows: after adopting the clamping device of above-mentioned symmetrical bending pipe arm, it is original 1/2nd that the overall structure size of bending pipe arm is reduced into, and weight alleviates greatly, and the inertia during bend pipe is corresponding to be reduced, and bend pipe speed is improved; And the clamping device of above-mentioned symmetrical bending pipe arm, become single driving by two original drivings, its simple in structure, small volume, and also cost is lower, and corresponding control program also reduces control point and test point.

Among the figure: 1, bending pipe arm, 2, clamp slide plate, 3, clamping seats, 4, clamping cylinder, 5, coupling block, 6, synchronizing bar, 7, front rod, 8, back link, 9, adjustment seat, 10, adjustment screw.
The specific embodiment
Be described in further detail below by the clamping device of specific embodiment to the symmetrical bending pipe arm of the present invention.
As shown in Figure 1, the clamping device of symmetrical bending pipe arm, comprise the clamping slide plate 2 that is movably arranged on respectively bending pipe arm 1 both sides, each clamps on the slide plate 2 and is provided with clamping seats 3, be provided with a clamping cylinder 4 on the bending pipe arm 1, clamping cylinder 4 can make cylinder also can make oil cylinder or other driver parts, be provided with coupling block 5 on the motion bar of clamping cylinder 4, be movably set with two synchronizing bars 6 on the coupling block 5, one end of two synchronizing bars 6 all is flexibly connected mutually with coupling block 5, and the other end of each synchronizing bar 6 is flexibly connected mutually with corresponding clamping slide plate 2.
As preferred version, each front and back end that clamps slide plate 2 is respectively arranged with front rod 7 and back link 8, front rod 7 and back link 8 are arranged in parallel, and an end of front rod 7 and back link 8 is flexibly connected mutually with clamping slide plate 2, and the other end of front rod 7 and back link 8 and bending pipe arm 1 are flexibly connected.By the setting of front rod 7 and back link 8, clamping slide plate 2 when bending pipe arm 1 slides, front rod 7, back link 8 and clamping slide plate 2 form a parallel-crank mechanism, move more reliable and more stable.
As preferred version, described clamping seats 3 is movably arranged on and clamps on the slide plate 2, clamps on the slide plate 2 and is provided with adjustment seat 9, is provided with adjustment screw 10 in the adjustment seat 9, and the end of adjustment screw 10 contacts with clamping seats 3.When between pipe fitting and clamping seats 3, also having less gap, can pass through degree of tightness adjustment screw 10, realize the purpose of fine setting clamping seats 3 front and back positions, thereby make clamping more firm.
As shown in Figure 1, the clamping device of above-mentioned symmetrical bending pipe arm 1 is in the folder state that moves back, during work, motion bar by clamping cylinder 4 stretches out, drive two synchronizing bars 6 by coupling block 5 and move forward, thereby drive two clamp slide plates 2 on bending pipe arm 1 synchronously to front slide, when clamping slide plate 2 slip, front rod 7 and back link 8 swing synchronously, and then drive clamping seats 3 and move forward the clamping pipe fitting, and its state as shown in Figure 2.
The above embodiments are principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used for restriction the present invention; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, these all belong to protection scope of the present invention.
