Abstract
The utility model discloses a non-circular cross-sectional curved surface grinding clamp, comprising a clamp body. A positioning sleeve is mounted on the clamp body via a fastening screw, and is provided with a positioning hole therein. The right end of the positioning hole has a conical structure. An eccentric elastic chuck is arranged in and matched with the positioning hole of the positioning sleeve. The right end of the eccentric elastic chuck has a conical surface that is matched with the conical structure of the right end of the positioning hole. The left end of the eccentric elastic chuck penetrates out of the positioning sleeve. The surface of the extended left end of the eccentric elastic chuck is provided with external threads. A locking sleeve is locked with the extended left end of the eccentric elastic chuck in a threaded-connection manner, and abuts against the left end face of the positioning sleeve. A rotatable screw is mounted on the positioning sleeve and is inserted into the positioning hole. The non-circular cross-sectional curved surface grinding clamp of the utility model has a simple structure. Workpieces can be clamped and positioned via the eccentric elastic chuck, thereby guaranteeing that punch workpieces can be reliably positioned and firmly clamped during the machining process.
Description
Technical field
The utility model 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 through 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.
The utility model content
The utility model technical problem to be solved provides a kind of curvilinear surface clamp of on-circular cross-section; It is simple in structure; Can in the curvilinear surface grinding that realizes on-circular cross-section, need not 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 scheme that the utility model adopts is:
A kind of curvilinear surface clamp of on-circular cross-section; Include clamp body; Through holding screw positioning sleeve is installed on the clamp body, has locating hole in the positioning sleeve, the tapered structure of the right-hand member of said locating hole; The eccentric collet that matches with it is arranged in locating hole of said 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 said eccentric collet stretches out, the left end locking that has lock sleeve to stretch out with eccentric collet through 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 in the utility model, can make the punch of processing can obtain clamping force uniformly and effectively like this, can not injure the surface of punch workpiece.
The mode of operation of the utility model is:
Pack in the eccentric collet punch workpiece 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 the completion 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 utility model 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.
The utility model has the advantages that:
The utility model is simple in structure; Can in the curvilinear surface grinding that realizes on-circular cross-section, need not 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
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Referring to Fig. 1; A kind of curvilinear surface clamp of on-circular cross-section includes clamp body 1, through holding screw 2 positioning sleeve 3 is installed on the clamp body 1; Have locating hole in the positioning sleeve 3; The tapered structure of the right-hand member of said locating hole has the eccentric collet 4 that matches with it in the locating hole of said positioning sleeve 3, the right-hand member of eccentric collet 4 has the conical surface that matches with the pyramidal structure of locating hole right-hand member; The left end of described eccentric collet 4 stretches out outside positioning sleeve 3; There is external screw thread on the surface of the left end that said eccentric collet 4 stretches out; The left end locking that has lock sleeve 5 to stretch out with eccentric collet 4 through being threaded, and inconsistent with the left side of positioning sleeve 3; On the described positioning sleeve 3 rotary screw 6 is installed, rotary screw 6 extend in the locating hole.
On the described lock sleeve 5 handle 7 is arranged.
