Description

Technical Field

[0001] This utility model relates to the field of machine tool fixture technology, and in particular to a clamping mechanism for a machine tool for processing irregularly shaped parts. Background Technology

[0002] Irregularly shaped parts are mainly those that are produced by enterprises themselves without strict national standards and specifications or relevant strict parameter regulations. There are many types of irregularly shaped parts, and due to their relatively irregular shapes, they usually require the use of corresponding clamping mechanisms for positioning during machine tool processing.

[0003] For example, the authorization announcement number "CN214685310U" is named a fixture mechanism for irregularly shaped workpieces. By setting this fixture mechanism on a CNC drilling machine, it is possible to center and clamp complex multidimensional irregularly shaped parts, making it possible to process irregularly shaped parts with CNC drilling machines and greatly improving the efficiency of drilling irregularly shaped parts.

[0004] The above-mentioned and existing technologies have the following defects: the distance between the vertical plate and the V-shaped centering frame of the clamping mechanism cannot be adjusted, and it can only clamp irregular workpieces of the same specifications, which limits its use; the end of the irregular workpiece near the vertical plate is not equipped with a supporting part, which means that when the irregular workpiece is fixed by the pressure plate, it is necessary to hold the irregular workpiece by hand and then tighten the connecting bolts, which is very inconvenient to operate. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a clamping mechanism for machining irregularly shaped parts on a machine tool.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

A second sliding groove communicating with the mounting cavity is provided on the upper surface of the base plate. A through hole is provided on the inner wall of the mounting cavity on the side away from the upright plate. A lead screw is provided inside the mounting cavity. One end of the lead screw is rotatably connected to the inner wall of the mounting cavity on one side. The other end of the lead screw is rotatably connected to the through hole through a first bearing. A handle is provided at the other end of the lead screw. A slider is threadedly connected to the surface of the lead screw. A support rod is provided on the upper surface of the slider. The upper end of the support rod passes through the second sliding groove and is connected to the lower surface of the V-shaped centering frame.

[0010] Preferably, the supporting device includes a support frame, the lower surface of which is provided with a support rod, the lower end of which slides through the base plate, and the surface of the support rod is threaded with two second fixing nuts, which are respectively located above and below the base plate.

[0011] Preferably, the threaded hole of the clamping device is opened on the surface of the top plate, and a first clamping rod is threadedly connected to the inner wall of the threaded hole. The upper end of the first clamping rod is provided with a first operating part, and a second clamping rod is threadedly connected inside the first clamping rod. The end of the second clamping rod away from the second irregular end is provided with a second operating part, and the end of the second clamping rod near the second irregular end is provided with a clamping end block.

[0012] Preferably, an end groove is provided on one side of the inner wall of the mounting cavity, and a rotating end block is provided at one end of the lead screw. The rotating end block is rotatably connected to the inner wall of the end groove through a second bearing.

[0013] The present invention proposes a clamping mechanism for machining irregularly shaped parts, which has the following advantages: Since a support device is provided at the end of the irregularly shaped part near the vertical plate, the height of the support can be adjusted by placing the second irregularly shaped end of the part onto the support frame and then tightening two second fixing nuts. This eliminates the need to manually support the irregularly shaped part when fixing it with the clamping device, making operation very convenient. Furthermore, the distance between the vertical plate and the V-shaped centering frame is adjustable, allowing for the clamping of irregularly shaped workpieces of different specifications, thus broadening its application range.
