Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a maintenance clamp for mechanical parts. Background Art

[0002] Mechanical parts processing refers to the process of changing the size or performance of mechanical parts through mechanical equipment. In the process of mechanical parts processing, in order to fix the mechanical parts, it is usually necessary to use a clamp to clamp the mechanical parts. At present, the existing mechanical parts maintenance clamps are generally three-jaw chucks, or clamps that can adjust the relative movement or forward and backward movement of two flat plates (or curved plates).

[0003] However, no matter which type of clamp is used, there are relatively large limitations when it is used, that is, the three-jaw chuck is mainly suitable for tubular mechanical parts, but not for plate-shaped mechanical parts; on the contrary, the other type of clamp mentioned above is difficult to be used for clamping and fixing tubular mechanical parts;

[0004] In addition, after the existing clamps clamp and fix the mechanical parts, the mechanical parts cannot be flipped and adjusted. When other parts of the mechanical parts need to be repaired, the clamping and fixing of the mechanical parts must be released first, and then they must be clamped and fixed again. This operation is undoubtedly time-consuming and labor-intensive, which reduces the work efficiency of mechanical parts processing. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the above technical difficulties and provide a maintenance clamp for mechanical parts. When in use, by replacing different clamping plates, it is possible to clamp and fix mechanical parts of different shapes such as tubular or plate-shaped, and after clamping and fixing the mechanical parts, the mechanical parts can be conveniently flipped over without releasing the fixation.

[0006] In order to solve the above technical problems, the technical solution provided by the utility model is:

[0007] A maintenance fixture for mechanical parts, comprising a mounting base, a bracket, a rotating rod, a sleeve, a clamping plate, an adapter, a threaded rod and a threaded sleeve; the sleeve and the threaded sleeve are respectively fixed to the left and right sides of the mounting base through the bracket, the rotating rod is rotatably sleeved on the inner side of the sleeve, and after passing through the sleeve, the clamping plate is detachably mounted on the right end, the rotating rod is fixed to the inner side of the sleeve through a positioning structure after rotation, the threaded rod is threadably sleeved on the inner side of the threaded sleeve, and after passing through the threaded sleeve, the left end is rotatably connected to the adapter, the other end of the adapter is detachably mounted with a clamping plate, and the two clamping plates are arranged in left and right mirror images;

[0008] A plurality of clamping plates corresponding to the rotating rod or the threaded rod are provided, and the shapes of the clamping plates are different.

[0009] As an improvement, the clamping plate is a flat plate structure, mainly used for clamping and fixing mechanical parts with flat surfaces, and is also a V-shaped plate structure, mainly used for clamping and fixing tubular mechanical parts.

[0010] As an improvement, the back of the clamping plate is integrally formed with a plug-in column, the adapter is a cylindrical rod structure, and the right end face of the rotating rod and the left end face of the adapter are respectively provided with plug-in holes, and the plug-in column is plugged into the plug-in hole and fixed in the plug-in hole by bolts, so that the clamping plate can be easily loaded and unloaded, thereby facilitating its replacement.

[0011] As an improvement, a pair of limit stop rings are integrally formed in the middle of the rotating rod, and the two limit stop rings are movably connected to the two end surfaces of the tube sleeve respectively.

[0012] As an improvement, the positioning structure includes a handle screw and a positioning screw hole; a threaded through hole matching the handle screw is provided at the top of the sleeve, and a positioning screw hole matching the handle screw is provided on the rotating rod, and a plurality of positioning screw holes are evenly arranged along the circumference of the rotating rod, so that the rotating rods can be fixed after the two rotating rods are fixed, but they can only be fixed after the rotating rods are rotated to a fixed angle.

[0013] The advantages of the utility model compared with the prior art are:

[0014] 1. When using this new model, after clamping and fixing the mechanical parts between the two clamping plates, unscrew the handle screws, the clamping plates and the mechanical parts can be turned and rotated together with the rotating rod as the axis, and after the rotation, the mechanical parts can be conveniently fixed by installing the handle screws. In this way, the position of the mechanical parts can be turned more conveniently without releasing the clamping and fixing of the mechanical parts.

[0015] 2. When the present invention is in use, the clamping plate on the rotating rod or the adapter is a replaceable structure, and the loading and unloading and replacement operations are convenient, so that the present invention can be used for clamping and fixing tubular or plate-shaped mechanical parts, and is more practical.

[0028] The clamping plate 5 is a flat plate structure, and a plug-in column 9 is integrally formed on the back of the clamping plate 5. The adapter 6 is a cylindrical rod structure, and a plug-in hole 10 is reserved on the right end face of the rotating rod 3 and the left end face of the adapter 6. After the plug-in column 9 is plugged into the plug-in hole 10, it is fixed in the plug-in hole 10 by a bolt 11. The two clamping plates 5 are arranged in a mirror image on the left and right;
