Description

Technical Field

[0001] The utility model relates to the technical field of positioning mechanisms, and particularly relates to a positioning mechanism for the production of excavator parts. Background Technique

[0002] An excavator is an earthmoving machine that uses a bucket to excavate materials above or below the machine's surface and loads them into transport vehicles or unloads them onto a stockpile. During the production process of excavator parts, a positioning mechanism is usually required to position and fix the parts used in excavator production, so that during a series of processing operations such as grinding and welding, they can be fixed at the accurate position to avoid processing failures caused by offsets.

[0003] According to a mechanical part production auxiliary positioning device disclosed on the patent network (authorization announcement number: CN219311109U), it is described that "the utility model relates to the technical field of jigs, and particularly relates to a mechanical part production auxiliary positioning device, including a mounting base. A directional plate and a support plate are fixedly connected to the top of the mounting base. A guide rod is fixedly connected to the side of the directional plate and the support plate that are close to each other. A lead screw penetrates through the surface of the support plate movably. One end of the lead screw is movably connected to the directional plate, and the other end of the lead screw is fixedly connected to a first motor. Through the rotation of the lead screw driven by the first motor in the utility model, the clamping plate on the directional plate can approach the clamping plate on the directional plate. Then, through the rotation of the adjusting rod driven by the second motor, multiple clamping plates can approach each other, facilitating the clamping and fixing of cylindrical parts of different sizes. And through the design of the right-angle opening, the four corners of the rectangular part can be respectively arranged in the right-angle opening to complete the fixed clamping of the rectangular part, improving the applicability and avoiding the problem of wasting time and resources by replacing jigs."

[0004] Regarding the above description, the applicant believes there are the following problems:

[0005] During the use of this utility model, by setting the first motor to drive the lead screw to rotate and using the second motor to drive the adjusting rod to rotate, the clamping plates can approach each other for clamping. The design of the right-angle opening enables the clamping of rectangular parts. However, during actual use, the size of the right-angle opening is relatively small, and it can only slightly limit the corners of the rectangular part. It is difficult to stably fix the part with a small-opening right-angle opening. Therefore, it is necessary to improve a positioning mechanism for the production of excavator parts to solve the above problems. Content of the Utility Model
