[0004] The steel wheel of the aforementioned harmonic reducer needs to be pressed against other components by fasteners. The existing fastening method mainly uses bolts for fixing.

Therefore, it does not meet the existing requirements. To address this, a harmonic reducer with a pressing function is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a harmonic reducer with a clamping function to solve the problem mentioned in the background art that the steel wheel of the existing harmonic generator needs to be clamped to other components by fasteners. The existing fastening method is mainly fixed by bolts. During the disassembly and assembly process, external tools are required, which is inconvenient to operate. Moreover, the deeper the hole, the longer the operation takes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a harmonic reducer with a clamping function, comprising: a harmonic reducer body, a limiting assembly installed at the front end of the steel wheel hole of the harmonic reducer body, a clamping fitting installed inside the limiting assembly, the clamping fitting including an assembly rod inserted into the steel wheel hole, the front end of the assembly rod being restricted within the limiting assembly, and the rear end of the assembly rod being limited and fixed by a threaded component.

[0007] Preferably, the limiting assembly includes a limiting cavity, and two sets of first limiting blocks arranged in annular intervals are installed inside the limiting cavity. The outer wall of the first limiting blocks is provided with a locking hole.

[0008] Preferably, an end block is installed at the front end of the assembly rod, and two sets of protrusions are symmetrically arranged on the outer wall of the end block.

[0011] Preferably, an end cap is installed at the port of the limiting cavity.

[0012] Preferably, a through hole matching the steel wheel hole is provided at the middle position of the limiting cavity.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In this utility model, the assembly rod is inserted into the through hole, and the volume of the end block is larger than that of the assembly rod so that it is restricted inside the limiting cavity. The end block is rotated by the prying block, so that the protrusion of the end block moves to the first limiting block, and the locking block on the outer wall of the protrusion is inserted into the locking hole for combination and fixation. At the same time, the magnetic block abuts against and is restricted at the second limiting block, and the limiting assembly is combined and fixed together with the front end of the pressing assembly. The above structure is not affected by the hole depth, and can effectively assemble and combine the front end of the assembly rod, making it more convenient to perform assembly and pressing operations, and effectively improving assembly efficiency.

[0015] (2) In this utility model, after the front end of the assembly rod is assembled, a nut is installed at its tail end. During the installation process, the nut is rotated by the wing handle. The installation operation can be carried out without the aid of external tools. The above structure is used to restrict the assembly of the tail end of the assembly rod. Only the tail end has a thread for limiting the assembly. This structure can also be disassembled and removed without tools, which is convenient for users to assemble. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 This utility model provides an embodiment of a harmonic reducer with a clamping function, comprising: a harmonic reducer body 1, a limiting assembly 2 installed at the front end of the steel wheel hole of the harmonic reducer body 1, a clamping assembly 3 installed inside the limiting assembly 2, the clamping assembly 3 including an assembly rod 301 inserted into the steel wheel hole, the front end of the assembly rod 301 being restricted within the limiting assembly 2, and the rear end of the assembly rod 301 being limited and fixed by a threaded component, the limiting assembly 2 including a limiting cavity 203, two sets of annularly spaced first limiting blocks 204 installed inside the limiting cavity 203, the outer wall of the first limiting blocks 204 having a locking hole 205, an end block 302 installed at the front end of the assembly rod 301, and two sets of protrusions 3 symmetrically arranged on the outer wall of the end block 302. 03. A locking block 304 is installed on the end wall of the protrusion 303, which is inserted and removed from the locking hole 205. A bending block 309 is installed on the front end face of the end block 302. An end cover 201 is installed at the port of the limiting cavity 203. A through hole 202 matching the steel wheel hole is opened in the middle position of the limiting cavity 203. A second limiting block 206 is installed above the first limiting block 204. Two sets of magnetic blocks 305 are installed in a ring at intervals on the outer wall of the end block 302. The first limiting block 204 is used to limit the protrusion 303 at the end block 302. On this basis, the locking block 304 and the locking hole 205 enhance the stability of the limiting state of the two. The second limiting block 206 is used to magnetically combine with the magnetic blocks 305, which further improves the stability at this point.

[0024] During operation, the end cover 201 is opened, and the assembly rod 301 is inserted into the through hole 202. The volume of the end block 302 is larger than that of the assembly rod 301, so that it is restricted inside the limiting cavity 203. The end block 302 is rotated by the lever 309, so that the protrusion 303 of the end block 302 moves to the first limiting block 204, so that the locking block 304 on the outer wall of the protrusion 303 is inserted into the locking hole 205 for combination and fixation. At the same time, the magnetic block 305 abuts against and is restricted at the second limiting block 206, so that the limiting assembly 2 is combined and fixed together with the front end of the clamping assembly 3.

[0025] Please see Figure 4 The outer wall of the tail end of the assembly rod 301 is provided with an external thread 306 for the installation of threaded parts. The threaded parts include a nut 307, and multiple annularly spaced shanks 308 are installed on the outer wall of the nut 307. After the front end of the assembly rod 301 is assembled, the nut 307 is installed at its tail end. During the installation process, the nut 307 is rotated by the shanks 308, and the installation operation can be carried out without the aid of external tools.

[0026] During subsequent disassembly, first use the wing handle 308 to rotate the nut 307 to remove it, then use the pry bar 309 to rotate the end block 302 to disengage the locking block 304 from the locking hole 205, and then pull out the assembly rod 301 from the inside. This operation also does not require the use of tools, making it convenient for users to get started quickly.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
