Description

Technical Field

[0001] The utility model relates to the technical field of jigs, and particularly relates to an annular workpiece jig for the production of prototype models. Background Art

[0002] A prototype is one or several samples made according to the product appearance drawing or structure drawing without opening a mold, which is used to check the rationality of the appearance or structure. At present, prototypes are also called first samples in different places.

[0003] When processing an annular workpiece in a prototype model, a three-jaw chuck is mostly used for fixation. However, when surface drilling is required for the annular workpiece, since the table surface of the three-jaw chuck fits with the workpiece surface, it is difficult to perform double-sided through drilling.

[0004] Therefore, how to provide an annular workpiece jig for the production of prototype models to solve the problems existing in the prior art is of great significance for its application. Summary of the Utility Model

[0005] In view of this, the purpose of this application is to provide an annular workpiece jig for the production of prototype models to solve the problem that when processing an annular workpiece in a prototype model, a three-jaw chuck is mostly used for fixation, but when surface drilling is required for the annular workpiece, since the table surface of the three-jaw chuck fits with the workpiece surface, it is difficult to perform double-sided through drilling.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] An annular workpiece jig for the production of prototype models includes a bottom plate. A strip-shaped groove is provided in the middle of the bottom plate, and a left clamping block and a right clamping block are respectively and fixedly connected to both sides of the surface of the bottom plate;

[0008] A fixing block is installed at the top end of the bottom plate. Slide bars are slidably connected to both sides of the fixing block. The end of the slide bar is fixedly connected with a limiting block. A limiting groove is provided on the front surface of the limiting block. A lead screw is threadedly connected to the middle of the fixing block. One end of the lead screw is rotatably connected to the limiting block, and the other end of the lead screw is fixedly connected with a hand wheel.

[0009] Preferably, the left clamping block and the right clamping block are symmetrically arranged with the strip-shaped groove as the center, and the opposite surfaces of the left clamping block and the right clamping block are inclined.

[0010] Preferably, the shape of the limiting groove is V-shaped, and the bottom end of the limiting block is attached to the upper surface of the bottom plate.

[0011] Preferably, the strip-shaped groove penetrates through the upper and lower surfaces of the bottom plate, and the limiting block and the strip-shaped groove are on the same axis.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. The present utility model can clamp and fix the annular workpiece. When in use, place the annular workpiece on the top of the bottom plate, then make the bottom end of the workpiece fit against the side surfaces of the left and right clamping blocks, and then turn the handwheel. At this time, the handwheel drives the lead screw to rotate, thereby driving the limit block to move, so that the limit groove abuts against the top end of the workpiece, completing the clamping of the workpiece. By providing the strip-shaped groove, drilling can be realized on the surface of the annular workpiece. Compared with the existing fixtures, the present utility model can conveniently clamp and fix the annular workpiece, and is safer and more convenient to use.

[0014] 2. The present utility model can clamp annular workpieces with different diameters. Since the opposite surfaces of the left and right clamping blocks are both provided as inclined surfaces, annular workpieces with any diameter can abut against the inclined surfaces of the left and right clamping blocks. At the same time, the movable limit block can realize the clamping and fixing of workpieces with different diameters. The present utility model has a wider application range and strong applicability.
