Abstract

The utility model provides a clamp special for planing, belonging to the technical field of machining; the clamp special for planing comprises two clamping parts which are arranged oppositely, wherein each clamping part comprises a bottom plate, a connecting plate is arranged on each bottom plate, and the connecting plates are vertically connected with the bottom plates; the bottom plate is further provided with a clamp block, the inner side wall of the clamp block is arc-shaped and matched with the outer diameter of a workpiece to be processed, the bottom of the clamp block is fixedly connected with the bottom plate, and the back of the clamp block is fixedly connected with the connecting plate. Above-mentioned scheme, because the internal diameter of anchor clamps and the external diameter looks adaptation of treating the processing work piece, consequently when treating the work piece of processing and pressing from both sides tightly, can guarantee work piece non-deformable to keep its precision, and have the certain distance between two clamping parts, can avoid welding seam department, the planing of being convenient for.

Description

Special clamp for planing

Technical Field

The utility model relates to the technical field of machining, especially indicate a planing special fixture.

Background

At present, the weld reinforcement in the press-fit ring needs to be removed by adopting a planing method, the press-fit ring needs to be clamped by adopting a clamp firstly during planing, and the press-fit ring is easy to deform and influence the precision due to the fact that the diameter size and roundness precision of the press-fit ring are high in requirement when the press-fit ring is clamped by adopting a conventional clamp.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a planing special fixture is in order to solve at the planing in-process, when adopting conventional anchor clamps to carry out the clamping to the higher circle form work piece of required precision, leads to its deformation easily to reduce the problem of work piece precision.

In order to solve the technical problem, the utility model provides a following technical scheme:

a clamp special for planing comprises two clamping parts which are arranged oppositely, and a preset distance is arranged between the two clamping parts; the clamping part comprises a bottom plate, a connecting plate is arranged on the bottom plate, and the connecting plate is vertically connected with the bottom plate; the bottom plate is further provided with a clamp block, and the inner side wall of the clamp block is arc-shaped and matched with the outer diameter of a workpiece to be processed.

The special planing fixture further comprises a limiting plate, and the limiting plate is arranged on one side of the clamping part.

Wherein the width of the connecting plate is greater than the width of the clamp block.

The limiting plate is fixedly connected with one side of the connecting plate.

The bottom of the clamp block is fixedly connected with the bottom plate, and the back of the clamp block is fixedly connected with the connecting plate.

And a stepped counter bore for mounting a screw is arranged on the connecting plate.

Wherein, the central angle corresponding to the circular arc of the inner side wall of the clamp block is less than 180 degrees.

The utility model discloses an above-mentioned technical scheme's beneficial effect as follows:

in the above scheme, because the internal diameter of anchor clamps and the external diameter looks adaptation of treating the processing work piece, consequently when treating the work piece of processing and pressing from both sides tightly, can guarantee work piece non-deformable to keep its precision, and have the certain distance between two clamping parts, can avoid welding seam department, the planing of being convenient for.

Detailed Description

In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-2, an embodiment of the present invention provides a clamp for planing, including two clamping portions disposed opposite to each other, and a predetermined distance is provided between the two clamping portions; the clamping part comprises a bottom plate 1, a connecting plate 2 is arranged on the bottom plate 1, and the connecting plate 2 is vertically connected with the bottom plate 1; still be provided with anchor clamps piece 3 on the bottom plate 1, the inside wall of anchor clamps piece 3 is circular-arcly, the internal diameter of anchor clamps piece 3 and the external diameter looks adaptation of waiting to process work piece 4, just the width of anchor clamps piece 3 is less than the width of waiting to process work piece 4.

In this embodiment, the special planing fixture further includes a limiting plate 5, the limiting plate 5 is disposed on one side of the clamping portion, and when the special planing fixture is used, one side of the workpiece 4 can be abutted against the side face of the limiting plate 5 to limit the position.

As shown in fig. 2, the width of the connection plate 2 is greater than the width of the clamp block 3. And the limiting plate 5 is fixedly connected with one side of the connecting plate 2.

As shown in fig. 1, the bottom of the clamp block 3 is fixedly connected to the bottom plate 1, and the back of the clamp block 3 is fixedly connected to the connecting plate 2.

In this embodiment, the connecting plate 2 is provided with a stepped counter bore for mounting a screw, and the clamping portion can be connected to a vise of a planer by the screw when in use.

As shown in fig. 1, the outer side wall of the clamp block 3 is also arc-shaped, and both end surfaces of the clamp block 3 are flush with the end surface of the base plate 1.

Besides, the central angle corresponding to the arc of the inner side wall of the clamp block 3 is less than 180 degrees.

The utility model provides a planing special fixture use as follows:

when the clamp is used, the jaw is firstly loosened, a workpiece 4 to be machined is placed between the two clamp blocks 3, one side of the workpiece 4 is close to the limiting plate 5, and then the workpiece 4 is clamped.

It should be noted that, the width of the opening in the middle of the clamp needs to be greater than the width of the weld joint, so as to avoid the weld joint.

The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
