Technical Field
The utility model belongs to the technical field of the profile processing equipment, concretely relates to fixture that processing profile was used.
Background
As shown in fig. 1, the conventional clamping device for profile machining only includes a T-bolt 1, a nut 3, and a clamping plate 2, and the clamping plate 2 presses against the top surface of a workpiece to clamp the top surface of the workpiece. Therefore, the clamping area interferes with the tool and cannot be machined, and the clamping area is machined after secondary clamping. Therefore, the processing of the molded surface can be completed only by secondary processing, the processing precision of the workpiece is influenced, the processing efficiency of the molded surface of the workpiece is reduced, the processing cost is increased, and the cost for grinding the molded surface is increased. In addition, the secondary clamping of the workpiece can cause XY direction deviation, and the local machining amount is possibly insufficient.
Disclosure of Invention
In order to solve the technical problem, the utility model provides a simple structure can once the processing of clamping completion profile, improves the machining precision of production efficiency and profile, reduces the fixture that the processing cost's of profile processing profile was used.
The utility model adopts the technical proposal that: a clamping mechanism for machining a molded surface comprises a T-shaped bolt, a nut and a cushion block, wherein a T-shaped positioning key is arranged at the bottom of the cushion block and used for being matched with a T-shaped groove of a machine tool to realize cushion block positioning; the top of the cushion block is provided with a positioning screw and a positioning pin; the cushion block is connected with one end of the clamping plate, the clamping plate is horizontally arranged, and the clamping plate is provided with a bolt hole; the T-shaped bolt is vertically arranged, a screw rod of the T-shaped bolt penetrates through a bolt hole in the clamping plate, and a nut is arranged on the screw rod of the T-shaped bolt.
In the clamping mechanism for processing the molded surface, the cushion block is of a cuboid structure, a plurality of groups of clamping plate holes are arranged on the cushion block along the vertical direction, and each group of clamping plate holes comprises a plurality of clamping plate holes positioned in the same plane; one end of the clamping plate is inserted into a clamping plate hole; the top of the cushion block is provided with a screw hole for communicating the top surface with the uppermost clamping plate hole; the head of the screw is positioned in the uppermost clamping plate hole, and the rod part of the screw is exposed out of the top surface of the cushion block and is used for being connected with a workpiece.
In the clamping mechanism for machining the molded surface, the bolt holes in the clamping plates are long straight holes or waist-shaped holes; the screw hole at the top of the cushion block is a long straight hole or a waist-shaped hole.
In the clamping mechanism for machining the molded surface, the bottom of the cushion block is provided with two T-shaped positioning keys which are arranged in parallel.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model has simple structure and low cost; when the utility model is used for processing the profile, the cushion block is adopted to support the workpiece, and the workpiece is positioned through the connection of the screw and the threaded hole at the bottom of the workpiece; the processing of the molding surface is finished by one-time clamping without secondary clamping, the production efficiency and the processing precision of the molding surface are improved, and the processing cost of the molding surface is reduced.

Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 2, the utility model discloses a T type bolt 1, nut, 3, splint 2 and cushion 4, the bottom of cushion 4 be equipped with two parallel arrangement's T type navigation key 7 for with the T type groove cooperation of lathe, realize that cushion 4 fixes a position on the lathe.
Cushion 4 be the cuboid structure, cushion 4 on be equipped with two sets of double-layered plate hole 41 along vertical direction, every group double-layered plate hole is including two double-layered plate holes that are located the coplanar. The top of cushion 4 is equipped with the cotter hole, and the cotter hole is vertical to be set up, and the cotter downthehole locating pin 5 that is equipped with of cotter, locating pin 5 are used for cooperating with the cotter hole of work piece bottom, realize the location to the work piece. The top of cushion 4 still is equipped with the screw hole of intercommunication top surface and the top splint hole, and the screw hole is long straight hole. Be equipped with screw 6 in the screw hole, the head of screw 6 is located the splint hole of the top, and 4 top surfaces of cushion are exposed in the pole portion of screw 6 for be connected with work piece bottom screw hole, fasten the work piece.
One end cartridge of splint 2 in a splint hole 41 of cushion 4, splint 2 level sets up, is equipped with bolt hole 21 on splint 2, bolt hole 21 is the long straight hole, also can adopt waist type hole.
