Description

Technical Field

[0001] The utility model relates to the technical field of lathe tools, in particular to an end surface pressing clamp. Background Art

[0002] At present, in the process of machining mechanical parts, it is often necessary to fix the parts. If the parts are not fixed, the parts will shift during the machining process, resulting in low part machining accuracy.

[0003] The common lathe clamping process for annular workpieces generally adopts the outer diameter or inner diameter clamping method for processing, and the more common methods are the three-jaw chuck form or the rubber internal expansion clamp form. These two methods have certain requirements for the deformation of the blank before clamping, especially when the wall thickness of the processed shape is thin or the processed material is soft. If the blank is deformed greatly before clamping, it cannot be corrected in the later processing. In view of the shortcomings of the prior art, the utility model provides an end face clamp to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides an end face clamping clamp, which does not generate radial clamping force, so it can better ensure the radial deformation of the product. Because the end face clamping method usually makes it impossible to process the inner diameter or outer diameter, it is usually processed in conjunction with other precision clamps to better exert the performance of the precision clamp.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: an end face pressing clamp, comprising a clamp body, on which a plurality of groups of cylinder bodies are arranged, and a clamping block is arranged at the output end of the cylinder body;

[0006] A screw seat is fixedly connected to the clamp body, and an adjusting bottom support for supporting the workpiece is arranged inside the screw seat.

[0007] Preferably, an external thread is provided on the outer side of the adjusting base and the external thread is threadably connected to the inner side of the screw seat.

[0008] Preferably, a product drag ring is fixedly connected to the interior of the adjustable base.

[0009] Preferably, the interior of the adjusting base is fixedly connected with a plurality of groups of reinforcing ribs.

[0010] Preferably, a plurality of groups of cylinder fixing holes are provided on the clamp body, and an air pipe base is provided at the bottom of the clamp body.

[0011] Preferably, a plurality of connection blocks are fixedly connected to the clamp body, and a chuck is fixedly connected to the connection block.

[0012] The utility model discloses an end face pressing clamp, which has the following beneficial effects:

[0013] The end face clamping clamp has a compatible clamp body, which is suitable for clamping annular parts. The workpiece is not easily deformed during the clamping process. The adjustable base design makes it easy to correct the position and reduce the cost of tooling production. The clamp body is an automatic clamp, which reduces labor intensity. The clamping force is more stable due to air pressure control, which improves the stability of product quality, reduces scrap, and reduces the difficulty of product clamping. Compared with common end face clamps on the market, this clamp is cheaper, easier and quicker to replace, and can be used for small batch production. BRIEF DESCRIPTION OF THE DRAWINGS
