[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] In this application, unless otherwise clearly specified and limited, the terms "connection" and "fixation" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0023] In the description of the present application, it should be understood that the terms "longitudinal", "transverse", "horizontal", "top", "bottom", "up", "down", "inside" and "outside" etc. indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0024] In addition, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the present utility model, the meaning of "plurality" is more than two, unless otherwise clearly and specifically limited.

[0025] like Figure 1-4 As shown, the utility model provides a combined clamp suitable for irregular workpieces, including a fixing plate 10 , a clamping screw 20 and a clamping member 30 .

[0026] The fixing plate 10 is arranged in the transverse direction, and the two ends of the fixing plate 10 are fixed by chucks or other fixing devices. The fixing plate 10 is provided with a limiting opening 11 which runs through in the longitudinal direction, and the shape of the limiting opening 11 is not set. In this embodiment, the cross-sectional shape of the limiting opening 11 is preferably a triangle.

[0027] The clamping screw 20 is disposed on the fixing plate 10 in a transverse direction and is threadedly connected to the fixing plate 10 . The threaded end of the clamping screw 20 passes through the fixing plate 10 and extends into the limiting opening 11 .

[0028] The pressing member 30 is disposed in the limiting opening 11 and is rotatably connected to the threaded end of the pressing screw 20 .

[0029] The use process of the clamp is as follows: first, the worker places the irregular workpiece in the limit opening 11 with one hand. Then, the worker rotates the clamping screw 20 with the other hand, and the clamping screw 20 drives the locking member to move inward until the clamping member 30 presses the irregular workpiece against the inner wall of the limit opening 11, thereby forming a stable clamp for the irregular workpiece. Then, the processing equipment is started to process the upper part of the irregular workpiece.

[0030] Since the clamping piece 30 is rotatably connected to the threaded end of the clamping screw 20 , when the worker rotates the clamping screw 20 , the clamping piece 30 does not rotate together, thereby preventing the clamping piece 30 from scratching or wearing the irregular workpiece.

[0031] In one embodiment, the middle portion of the clamping member 30 is rotatably connected to the threaded end of the clamping screw 20. This design makes the force applied by the clamping screw 20 to the clamping member 30 more balanced, thereby making the force on the irregular workpiece more uniform and improving the stability of the clamp.

[0032] In one embodiment, at least two locking assemblies 40 are disposed below the fixing plate 10 and are arranged at equal intervals along the circumference of the limiting opening 11 .

[0033] The locking assembly 40 includes a fixing block 41 and a locking screw 42. The fixing block 41 is fixedly connected to the fixing plate 10. The locking screw 42 passes through the fixing block 41 in the transverse direction and is threadedly connected to the fixing block 41, and the threaded end of the locking screw 42 is located directly below the limiting opening 11.

[0034] After the clamping member 30 presses the irregular workpiece against the inner wall of the limiting opening 11, the staff rotates the locking screw 42 in each locking assembly 40, and the locking screw 42 moves inward until the threaded end of the locking screw 42 abuts against the lower part of the irregular workpiece. In this way, all the locking screws 42 cooperate to clamp the lower part of the irregular workpiece, further improving the clamping stability of the irregular workpiece.

[0035] In one embodiment, there are four locking assemblies 40 , which together clamp the lower portion of the irregular workpiece in four directions.

[0036] In one embodiment, a rubber pad is fixedly mounted on the threaded end of the locking screw 42. As the locking screw 42 rotates, the threaded end of the locking screw 42 will rotate and contact with the surface of the irregular workpiece and press against it, which may easily scratch the surface of the irregular workpiece. The design of the rubber pad can prevent the locking screw 42 from directly contacting the irregular workpiece, thus playing a certain protective role.

[0037] In one embodiment, the clamping member 30 is a cylindrical structure. The clamping member 30 with a cylindrical structure can better adapt to the outer surface of an irregular workpiece, further improving the adaptability of the clamp.

[0038] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is defined by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model.

[0039] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
