[0002] The jaws refer to the parts in the chuck used to clamp and hold the workpiece in the mechanical structure, or the machine tool accessories used to clamp and position the workpiece. Most of them are evenly distributed 360 degrees, so that the three jaws can approach or withdraw from the center at the same time to complete the work.

[0003] The machine tool claws in the prior art mainly include a claw body, rectangular sliders that slide with the chuck body on both sides, and a spiral groove at the bottom. When in use, the claw body and the chuck body are fixed, and then under the action of the spiral groove, the claw body can move, thereby clamping and fixing the object.

[0004] However, in actual use, the clamping part of the claw body is very easy to wear, which leads to a decrease in the clamping effect. At this time, the entire body needs to be replaced, which increases the overall cost of use. In addition, the clamping length of the claw body is often fixed. When objects of different sizes need to be clamped, different claw bodies need to be replaced, which is very inconvenient. Utility Model Content

The adjusting and disassembling structure 3 comprises a rectangular clamping block 31, and a rectangular clamping frame 33 is clamped on the outer surface of the rectangular clamping block 31. By arranging the rectangular clamping block 31 and the rectangular clamping frame 33, a clamping plate 35 can be auxiliary fixed, and a clamping plate 35 is fixedly connected to one side of the outer surface of the rectangular clamping frame 33. By arranging the clamping plate 35, an object can be clamped.

[0027] Specifically, Figure 2 and Figure 3As shown, a threaded clamping rod 34 is inserted into the top inner wall of the rectangular clamping frame 33, and a threaded clamping hole 32 is opened on the top of the outer surface of the rectangular clamping block 31. The threaded clamping rod 34 and the threaded clamping hole 32 are detachably threadedly connected. By setting the threaded clamping rod 34 and the threaded clamping hole 32, the rectangular clamping block 31 and the rectangular clamping frame 33 can be disassembled and assembled. An auxiliary sliding groove 36 is opened on one side of the outer surface of the clamping plate 35, and a movable plate 38 is slidably inserted into the inner wall of the auxiliary sliding groove 36. By setting the auxiliary sliding groove 36, the position of the movable plate 38 can be adjusted. A first protrusion 39 is fixedly connected to one side of the outer surface of the clamping plate 35, and a second protrusion 310 is fixedly connected to one side of the outer surface of the movable plate 38. By setting the first protrusion 3 9 and the second protrusion 310 can assist in fixation. The inner wall of the clamping plate 35 is located on the inner wall of the auxiliary sliding groove 36 and is provided with a round hole 37. The inner wall of the movable plate 38 is threadedly inserted with a threaded rod 312. By setting the threaded rod 312 and the round hole 37, the movable plate 38 can be auxiliary fixed. The inner wall of the movable plate 38 is located on the periphery of the threaded rod 312 and is provided with a receiving groove 311. One end of the threaded rod 312 is fixedly connected with a round clamping block 313. By setting the round clamping block 313 and the receiving groove 311, the round clamping block 313 can be received in the inner wall of the receiving groove 311. The round clamping block 313 is clamped with the receiving groove 311, and one end of the threaded rod 312 is threadedly connected with a fixing nut 314.

By setting the moving wheel 43, disassembly and assembly can be assisted, one side of the outer surface of the claw body 1 is fixedly connected with a U-shaped operating rod 44, and one side of the outer surface of the U-shaped operating rod 44 is fixedly connected with an anti-sliding block 45. By setting the U-shaped operating rod 44, the installation of the claw body 1 can be assisted.

[0029] The working principle of the utility model is:

[0030] S1. During installation, the rectangular ring frame 41 is inserted into the slide groove on the chuck body. At this time, the moving wheel 43 will slide on the inner wall of the slide groove. At this time, the butterfly gear on the chuck body is rotated so that the spiral strip on the top and the spiral groove 2 at the bottom of the claw body 1 are slidably installed. The U-shaped operating lever 44 can be pulled for operation throughout the whole process;

[0031] S2. When the clamping plate 35 needs to be installed, the rectangular clamping block 31 is clamped into the inner wall of the rectangular clamping frame 33, and then the threaded clamping rod 34 is rotated and screwed into the inner wall of the threaded clamping hole 32, and the clamping plate 35 is fixed;

[0032] S3. When adjustment is required, pull the movable plate 38 to make it slide on the inner wall of the auxiliary slide groove 36. After moving to the appropriate position, rotate the threaded rod 312 so that it can be inserted into the inner wall of the round hole 37, so that the round block 313 can be stuck into the inner wall of the storage groove 311. At this time, fix the fixing nut 314 and the threaded rod 312.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" 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 it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0034] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
