Description

A polishing jig

technical field

The utility model relates to the field of workpiece production, in particular to a polishing fixture. the

Background technique

After the stamping of the workpiece is completed, its surface is generally dirty and contains many burrs, and generally needs to be polished before use. In order to obtain a bright and smooth surface of the workpiece, the workpiece will be ground and polished when processing the workpiece. the

The polishing jigs in the prior art are mostly as shown in Figure 1, and a counterbore 12 of a corresponding shape is milled on the chassis 11 of the polishing jig, and the workpiece 01 to be polished can be placed at the corresponding counterbore 12, as shown in Figure 2 As shown, the workpiece 01 can be fixed on the polishing fixture with the screw 02 through the counterbore, so that the polishing machine can polish the workpiece 01. the

The inventor found that the polishing jig in the prior art needs to mill out different counterbores on the chassis for different workpieces, which leads to a large number of counterbores on the fixture, relatively high manufacturing cost and long production cycle time. the

Utility model content

The embodiment of the utility model provides a polishing fixture, which can adapt to different workpieces and has low manufacturing cost. the

In order to achieve the above object, the embodiments of the present utility model adopt the following technical solutions:

A polishing fixture includes: a pressure plate and a chassis, the chassis is provided with at least one clamping groove, and the clamping groove is used for fixing a workpiece. the

Preferably, the card slots are arranged at equal intervals. the

Optionally, the chassis is a circular chassis, and the length of the locking slot is greater than 1/2 of the radius of the circular chassis. the

Preferably, 12 card slots are arranged at equal intervals on the lower plate. the

Preferably, the card slot is a rectangular card slot. the

In the polishing jig provided by the utility model, a clamping groove is arranged on the chassis of the polishing fixture, and then a workpiece is fixed on the chassis by applying screws through the clamping groove. Compared with milling various counterbores on the chassis to adapt to different workpieces in the prior art, each slot in the utility model can adapt to workpieces of various structures, which has a short production cycle, low cost, and the application of card The groove can also freely adjust the fixed position of the workpiece. the

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. the

The embodiment of the utility model provides a polishing jig, as shown in FIG. 3 , the polishing jig includes: a chassis 31 and a pressure plate 32 . The chassis includes a connecting shaft 310 , and there is a groove (not shown in the figure) corresponding to the connecting shaft 310 on the pressure plate 32 , the connecting shaft 310 is engaged with the groove to connect the chassis 31 and the pressure plate 32 . the

As shown in FIG. 4 , at least one clamping slot 311 is provided on the chassis 31 , and the clamping slot 311 is used to fix the workpiece. the

Fig. 5 is a cross-sectional view of Fig. 4 along the direction B1-B2. the

When the polishing fixture provided by the utility model is used, screw holes are milled on the back of the workpiece, so as to fix the workpiece. For example, as shown in FIG. 5 , the operator can use screws 34 to fix the workpiece 33 on the chassis 31 through the slot 311 . the

When polishing the workpiece 33, first place the workpiece 33 above the predetermined slot, the screw hole on the back of the workpiece 33 faces the slot, move the workpiece 33 to the corresponding position along the direction of the slot, and screw the workpiece 34 to the corresponding position. 33 fixed. Then, the pressure plate 32 can be fastened on the top of the chassis, and the workpiece 33 can be polished by a polishing machine. the

In the polishing jig provided by the utility model, a clamping groove is arranged on the chassis of the polishing fixture, and then a workpiece is fixed on the chassis by applying screws through the clamping groove. Compared with milling various counterbores on the chassis to adapt to different workpieces in the prior art, each slot in the utility model can adapt to workpieces of various structures, and it is not necessary to mill out counterbores in comparison with various workpieces , the production period is short, the cost is low, and the fixed position of the workpiece can be adjusted arbitrarily by using the card slot. the

Preferably, the card slots on the chassis 31 are arranged at equal intervals. the

Preferably, as shown in FIG. 4 , the chassis 31 is a circular chassis, and the length of the locking slot 311 is greater than 1/2 of the radius of the circular chassis. There are 12 card slots arranged at equal intervals on the chassis 31 . the

Preferably, the card slot on the chassis 31 is a rectangular card slot. the

The above is only a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto, and any skilled person familiar with the technical field can easily think of changes within the technical scope disclosed in the utility model Or replacement, all should be covered within the scope of protection of the present utility model.
