Hereinafter, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present disclosure, unless otherwise specified, the meaning of "a plurality" is two or more.

[0022] Referring to Figure 1 With Figure 2 Shown is a shaft box puller for a slicing machine, which includes a positioning seat 31, a worm and worm gear mechanism 32, and a positioning rod 35. The worm and worm gear mechanism 32 is installed on the positioning seat 31. The input end of the worm and worm gear mechanism 32 is connected with a handwheel 33, and its output end is connected with a lifting screw rod 34. An external thread 341 is formed at the lower end of the lifting screw rod 34, and the external thread 341 is adapted to the threaded hole on the end face of the shaft box 2. That is, during use, one end of the lifting screw rod 34 can be aligned with the threaded hole, and then the puller is rotated as a whole so that the external thread 341 is screwed into the threaded hole. One end of the positioning rod 35 is connected to the positioning seat 31, and the other end is inserted into the corresponding hole position of the machine chamber 1, that is, the puller is positioned with the machine chamber 1. Then the staff rotates the handwheel 33, so that the lifting screw rod 34 is driven by the worm and worm gear mechanism 32 to move up and down relative to the positioning seat 31, so as to realize loading the shaft box 2 into the machine chamber 1 or pulling the shaft box 2 out of the machine chamber 1. In this embodiment, the worm and worm gear mechanism 32 can adopt a conventional and mature design scheme in the industry, which usually includes a mutually meshing worm and worm gear. The handwheel 33 is connected to one end of the worm, and the staff can drive the worm to rotate by itself through the handwheel 33. An internal thread matching with the lifting screw rod 34 is arranged on the inner ring of the worm gear. When the worm gear rotates, the lifting screw rod 34 can be driven to move up and down.

[0023] In some possible embodiments, a guide sleeve 36 is further fixed on the positioning seat 31. The guide sleeve 36 is arranged at the lower end of the positioning seat 31. One end of the lifting screw rod 34 passes through the guide sleeve 36 and is drivingly connected with the worm and worm gear mechanism 32. A guide post 361 protrudes from the inner ring of the guide sleeve 36, and a guide groove 342 extending along its length direction is formed on the outer side surface of the lifting screw rod 34. The guide post 361 is arranged in the guide groove 342. Further, there are two guide posts 361 and they are arranged at intervals in the vertical direction. The outer diameter dimension of the guide post 361 is adapted to the width dimension of the guide groove 342, and the purpose is to prevent the problem that the lifting screw rod 34 rotates by itself during work and causes the work to fail.

[0024] In some possible embodiments, positioning slots 311 are respectively formed at both ends of the positioning seat 31. A positioning ring platform 351 is provided at one end of the positioning rod 35 and is adapted to be horizontally engaged with the positioning slot 311. The positioning ring platform 351 can be horizontally snapped into the positioning slot 311 to facilitate the relative rotation of the positioning seat 31 and the lifting screw rod 34 with respect to the axle box 2, so as to connect or disconnect the lifting screw rod 34 from the axle box 2. The height dimension of the positioning ring platform 351 is greater than the depth dimension of the positioning slot 311 to ensure that the positioning rod 35 has sufficient margin for vertical movement so that its lower end can be inserted into the hole position of the machine compartment 1.

[0025] In some possible embodiments, a positioning pin shaft 352 is formed at the other end of the positioning rod 35. The outer diameter dimension of the positioning pin shaft 352 is smaller than the outer diameter dimension of the positioning rod 35, and the outer diameter dimension of the positioning pin shaft 352 is also smaller than the aperture diameter of the hole position of the machine compartment 1. The outer diameter dimension of the positioning rod 35 is greater than the aperture diameter of the hole position of the machine compartment 1 to ensure that the positioning rod 35 can be inserted and stably supported by the machine compartment 1, thereby realizing the positioning connection between the positioning seat 31 and the machine compartment 1.

[0026] In some possible embodiments, the positioning seat 31 is in the shape of a rectangular plate, and the positioning slots 311 are respectively arranged at the four corners of the positioning seat 31. Further, one side of the positioning slot 311 is open, and the positioning ring platform 351 can be horizontally placed into the positioning slot 311 from the opening to realize the detachable connection between the positioning rod 35 and the positioning seat 31; generally, two positioning rods 35 respectively arranged at both ends of the positioning seat 31 can meet the requirements. The design of the present invention can make the positioning seat 31 adapt to more size models or machine compartments 1 with different hole position designs.

[0027] In some possible embodiments, the worm and worm gear mechanism 32 is installed on the upper end surface of the positioning seat 31. A reinforcing rib 37 extending along its length direction protrudes from the lower end surface of the positioning seat 31 to enhance the structural strength of the positioning seat 31. Further, the reinforcing rib 37 extends from one end of the positioning seat 31 along the length direction of the positioning seat 31 to the other end to prevent problems such as deformation, bending, or cracking of the positioning seat 31 due to excessive force.

[0028] In some possible embodiments, both the positioning seat 31 and the lifting screw rod 34 are made of cemented carbide materials.

[0029] As described above, the above are only the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
