Description
Technical field
The utility model relates to the clamping clip technical field, relates in particular to a kind of clamping clip that can control the jaw opening angle automatically that is used on the material machine of rotary heating furnace dress mountain.
Background technology
Clamping clip is one of key equipment on the charging and discharging machine of rotary heating furnace.What the clamping clip oil cylinder adopted on the present charging and discharging machine is common oil cylinder, and this set is not a lot of can meeting the demands for stove blank specification; But for the more situation of special blank specification kind, the clamping clip of the common oil cylinder of this configuration just can't adapt to.Therefore, be necessary technical scheme of the prior art is done further improvement, to remedy defective of the prior art.
Summary of the invention
The purpose of this utility model is at the problems referred to above, a kind of blank that can grasp different size smoothly is provided, can controls the clamping clip of jaw opening angle automatically.
For achieving the above object, the technical solution of the utility model is as follows: the clamping clip that can control the jaw opening angle automatically, especially the clamping clip on the charging and discharging machine of rotary heating furnace, it includes and is hinged on the clamping screw die of first on the charging and discharging machine frame and the second clamping screw die, one end of the first clamping screw die and the second clamping screw die is hinged with the cylinder body and the piston rod of clamping cylinder respectively, and two clamp screw die by intermeshing sector gear connection; The opposite end hinged with clamping cylinder is jaw, finish jaw opening and closing and clamping by the action of clamping cylinder, it is characterized in that, described clamping cylinder disposes displacement transducer, displacement transducer links to each other with controller, and controller links to each other with hydraulic system and controls the action of clamping cylinder.
Described hydraulic system includes servo valve, and controller is connected with servo valve by servo valve driving clamping cylinder.
Described displacement transducer is a magnetostrictive displacement sensor, and the magnet ring of magnetostrictive displacement sensor is connected on the piston rod of clamping cylinder and along with piston rod moves together.
The beneficial effects of the utility model: clamping cylinder configuration bit displacement sensor detects the stroke of oil cylinder piston bar, cooperates the action of controller control oil cylinder, thereby satisfies the requirement of grasping the different size blank.
Description of drawings
Fig. 1 opens the extreme position structural representation for an embodiment's of the utility model;
Fig. 2 is the clamping extreme position structural representation of an embodiment of the utility model;
Fig. 3 is the utility model control principle figure.
Among the figure: 1-the first clamps screw die, 2-clamping cylinder piston rod, and 3-clamping cylinder cylinder body,
4-the second clamps screw die, 5-sector gear, and 6-jaw,
7-displacement transducer.
The specific embodiment
In conjunction with the accompanying drawings the utility model is described further with specific embodiment below, referring to Fig. 1 to 3:
The clamping cylinder configuration bit displacement sensor 7 of clamping clip detects the stroke of oil cylinder piston bar on the charging and discharging machine of rotary heating furnace, cooperates the action of controller control oil cylinder, thereby satisfies the requirement of grasping the different size blank.Specifically be achieved by the following scheme: it includes and is hinged on the clamping screw die 1 of first on the charging and discharging machine frame and the second clamping screw die 4, one end of the first clamping screw die 1 and the second clamping screw die 4 is hinged with clamping cylinder cylinder body 3 and clamping cylinder piston rod 2 respectively, and the opposite end hinged with clamping cylinder is jaw 6.Drive first and clamp screw die 1 and second and clamp screw die 4 and install around the rotation of discharging machine frame by the relative cylinder body of piston rod is flexible, thereby jaw 6 is opened or close up the generation clamping force.In order to make first to clamp the motor coordination that screw die 1 and second clamps screw die 4, two clamp screw die connects by intermeshing sector gear 5.
Described clamping cylinder disposes displacement transducer 7, and displacement transducer 7 links to each other with controller, and controller links to each other with hydraulic system and controls the action of clamping cylinder.Displacement transducer 7 can detect the stroke of oil cylinder piston bar in real time, thereby determines whether jaw 6 open angles reach the diameter of blank.Displacement transducer 7 sends to controller with detection signal, and controller is controlled hydraulic system according to pre-set programs.Hydraulic system includes servo valve, and controller is connected with servo valve by servo valve driving clamping cylinder.
Described displacement transducer 7 is a magnetostrictive displacement sensor; magnetostrictive displacement sensor utilizes the displacement of non-contact detecting movable magnet; because magnet there is no direct contacting with sensor; therefore this sensor is under abominable industrial environment; for example oil stain, solution, dust or other pollution do not constitute problem.In addition, magnetostrictive displacement sensor more can bear the environment of high temperature, high pressure and high vibration, and the signal of output is an absolute figure, so if the power interruptions reclosing can not receive the formation problem to data yet, more need not return to zero-bit again.Because sensing element all is noncontact, so, also can not cause any wearing and tearing to sensor even if detection process is constantly to repeat.Therefore magnetostrictive displacement sensor is fit to the clamping cylinder of clamping clip on the charging and discharging machine of rotary heating furnace very much.
In addition, the installation of displacement transducer 7 also is very important, and mounting means and installation accuracy directly have influence on measuring accuracy.The magnet ring of magnetostrictive displacement sensor is connected on the clamping cylinder piston rod 2 and along with piston rod moves together, the displacement of magnet ring moving sensing is the displacement that piston rod moves, just the displacement stroke of oil cylinder piston bar 2 in the utility model.
Above disclosed only is preferred embodiment of the present utility model, can not imprison this equivalence of being done according to the utility model claim and change with this interest field that limits the utility model certainly, still belongs to protection domain of the present utility model.
