Description

Non-magnetic material surface grinder fixture

technical field

The utility model belongs to non-magnetic material processing equipment, in particular to a non-magnetic material surface grinder fixture.

Background technique

When the surface grinder processes parts, the clamping method of the workpiece is generally processed by the magnetic adsorption of the workpiece on the work surface of the grinder. Non-magnetic material workpieces (such as non-ferrous metals such as copper and aluminum, and most steel materials) cannot be directly adsorbed on the work surface of the surface grinder, and the vise is used for indirect clamping or a few magnetic blocks to clamp the workpiece. The vise is clamped indirectly, and it is difficult to guarantee the parallelism and perpendicularity of the workpiece; most of the clamping is single-piece clamping, the production efficiency is low, and the consistency of the workpiece is poor; and it is greatly affected by the shape of the workpiece, and the special shape Special-shaped workpieces or thin-walled parts with low self-strength are difficult to clamp and process by these two methods.

Summarizing the above reasons, the traditional clamping method has the following disadvantages:

1. It is difficult to guarantee the tolerance of parts with high dimensional accuracy requirements;

2. It cannot be clamped in batches, the consistency of workpieces is poor, and the production efficiency is low;

3. It is greatly affected by the shape of the workpiece, and parts with special shapes cannot be clamped.

Contents of the invention

In order to solve the above-mentioned problems existing in the traditional clamping and processing parts, the utility model provides a non-magnetic material surface grinder clamp.

The utility model adopts the following technical solutions: a non-magnetic material surface grinder fixture, including a large flat plate made of magnetic material, one or more inner-shaped holes are arranged on the large flat plate, and parts to be processed are arranged in the inner-shaped hole. The above-mentioned large flat plate is composed of several small flat plates, and two adjacent small flat plates are respectively provided with matching grooves and protrusions, and the inner hole includes inner half holes a And inner type half hole b, inner type half hole a and inner type half hole b are yin and yang.

The part to be processed is hollow, and a mandrel is arranged inside the part to be processed.

Described small plate comprises small plate a, small plate b and small plate c, and the inside of small plate a and small plate c is provided with internal semi-hole a, and small plate b two sides are respectively provided with small plate a and small plate c The inner half-hole a fits the inner half-hole b.

The inner hole is circular or polygonal.

According to the shape of the part, the utility model uses a large plate of magnetic material with a certain thickness to cut the inner hole with the same shape as the part, and puts the workpiece into the inner hole. The size of the inner hole is cut according to the actual size of the workpiece. The hole is closely matched with the workpiece. According to the size of the part, multiple internal holes can be cut on the plate, and multiple parts can be placed at a time. Sometimes in order to facilitate the picking and placing of parts, the inner hole for placing the parts can be made into two halves, and the yin and yang are matched.

Compared with prior art, the utility model has the following advantages:

1. The verticality and parallelism of the workpiece can be well guaranteed, and the size consistency is good.

2. Multiple workpieces can be clamped and processed at one time, with high production efficiency;

3. The clamping is not limited by the shape of the parts, and special-shaped parts can also be clamped at will.

4. For thin-walled or hollow parts, a mandrel in the shape of the part is inserted in the middle to support it and then put it into the inner hole. The clamping does not deform, which improves the production quality of the workpiece.
