Abstract
The invention discloses a curve surface grinding clamp with a non-circular section. The grinding clamp comprises a clamp body, wherein a positioning sleeve is arranged on the clamp body through a fastening screw; a positioning hole is formed in the positioning sleeve; a right end of the positioning hole has a conical structure; an eccentric elastic chuck matched with the positioning sleeve is arranged in the positioning hole of the positioning sleeve; a right end of the eccentric elastic chuck is provided with a conical surface matched with the conical structure at the right end of the positioning hole; a left end of the eccentric elastic chuck stretches out of the positioning sleeve; an external thread is formed on the surface at the left end of the eccentric elastic chuck stretching out; a locking sleeve is locked with the left end of the eccentric elastic chuck stretching out through threaded connection and is pressed against a left end face of the positioning sleeve; and a rotating screw is arranged on the positioning sleeve and extends into the positioning hole. The grinding clamp has a simple structure, a workpiece is clamped and positioned through the eccentric elastic chuck, and a male die workpiece is reliably positioned and firmly clamped in the machining process.
Description
Technical field
The present invention relates to a kind of grinding positioner, mainly is a kind of curvilinear surface clamp of on-circular cross-section.
Background technology
Cold working mould punch is the consumable accessory in the diel, and the dimensional accuracy of punch working end and surface roughness have determined the quality of stamping parts stamping surface, directly influences the service life of product.The dimensional accuracy of punch working end and surface roughness value require very high, have only by the correct grinding outer surface just can reach.Because the punch working end is an on-circular cross-section, must use special clamp location and clamping, just can realize grinding at cylindrical grinder.
Summary of the invention
Technical problem to be solved by this invention provides a kind of curvilinear surface clamp of on-circular cross-section, it is simple in structure, can be in the curvilinear surface grinding that realizes on-circular cross-section, do not need to change the shape of abrasive grinding wheel, on common cylindrical grinder, can process, and can satisfy needed dimensional accuracy in punch working end and surface roughness, easy to operate.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of curvilinear surface clamp of on-circular cross-section, include clamp body, by holding screw positioning sleeve is installed on the clamp body, have locating hole in the positioning sleeve, the tapered structure of the right-hand member of described locating hole, the eccentric collet that matches with it is arranged in locating hole of described positioning sleeve, and the right-hand member of eccentric collet has the conical surface that matches with the pyramidal structure of locating hole right-hand member; The left end of described eccentric collet stretches out outside positioning sleeve, and there is external screw thread on the surface of the left end that described eccentric collet stretches out, the left end locking that has lock sleeve to stretch out with eccentric collet by being threaded, and inconsistent with the left side of positioning sleeve; On the described positioning sleeve rotary screw is installed, rotary screw extend in the locating hole.
On the described lock sleeve handle is arranged.
Eccentric collet has the surface of an end of the conical surface evenly to have three axial grooves among the present invention, can make the punch of processing can obtain clamping force uniformly and effectively like this, can not injure the surface of punch workpiece.
Mode of operation of the present invention is:
Pack into the punch workpiece in the eccentric collet and with the endoporus location, the positioning sleeve of packing into then has handle on the lock sleeve, turning handle connects external screw thread on lock sleeve internal thread and the eccentric collet and locks; Can not relatively rotate between these parts in the course of work.Unclamp holding screw then, positioning sleeve can relatively rotate in clamp body, evenly rotates rotary screw, carry out grinding raised die worker part one N-Side surf, rotate punch workpiece Rotate 180 ° after finishing again, the opposite side curved surface of grinding raised die worker's part, the grinding of punch workpiece makes two bites at a cherry.
The present invention has been owing to adopted eccentric collet that workpiece is clamped and locatees, and guaranteed that the punch workpiece locate in process reliably, and clamping is firm.
Advantage of the present invention is:
The present invention is simple in structure, can in the curvilinear surface grinding that realizes on-circular cross-section, not need to change the shape of abrasive grinding wheel, on common cylindrical grinder, can process, and can satisfy needed dimensional accuracy in punch working end and surface roughness, easy to operate.
Description of drawings
