Description

Technical Field

[0001] This utility model relates to a tool, and more specifically, a special wrench for locking fork bearings. Background Technology

[0002] Finished tobacco shreds are stored in standard tobacco boxes on the tobacco processing production line. When these boxes are stored in high-bay warehouses, the forks of a stacker crane are used to retrieve and place them. During the extension and retraction of the forks, transmission is achieved through both chain gears and rolling bearings on the forks for limiting the movement. There are many rolling bearings on both sides of the forks, and over time, wear and breakage can occur, leading to excessive resistance during fork extension and retraction and causing machine shutdowns. Therefore, the fork bearings need to be replaced periodically. The replacement process requires loosening the locking heads (bearing lock nuts) by striking them, which is time-consuming and labor-intensive due to the large number of fork bearings, and can also damage the locking heads. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model proposes a special wrench for locking fork bearings, which is used to quickly and conveniently disassemble the locking nuts of fork bearings.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A special wrench for locking fork bearings is used to assemble and disassemble the locking nuts that come with the fork bearings. The locking nut has multiple notches spaced apart along its circumference on its outer peripheral wall. These notches extend axially through the locking nut. Its structural features are: The forklift bearing locking wrench is divided into a head at one end of the handle, a handle, and a tail at the other end of the handle along its length. The overall structure is symmetrical along the width. The head is used to engage with the locking nut and includes a locking tooth seat and several locking teeth. The locking tooth seat is smoothly connected to the handle and has a flat surface. Several matching locking teeth are set on one side of the locking tooth seat according to the position and size of each notch. Each locking tooth protrudes outward in a direction perpendicular to the end face of the locking tooth seat. The locking tooth seat has a circular hole corresponding to the area enclosed by each locking tooth. The other end of the handle is rounded and has a centrally located hole, serving as the tail. The center of symmetry of the circular array of locking teeth, the center of the circular hole at the head, and the center of the hole at the tail are collinear.

[0005] The structural features of this utility model also lie in: The outer peripheral wall of the locking nut has four notches that are evenly spaced along the circumference. The tooth holder has four corresponding teeth that are adapted to each other. The fork bearing locking wrench is inserted into each notch one by one along the axial direction of the locking nut through the four teeth.

[0006] Compared with existing technologies, the beneficial effects of this utility model are reflected in: This utility model is a special tool designed to meet the production needs of periodic replacement of fork bearings. It is used to disassemble and install the locking nut that accompanies the fork bearing. The tool is structurally and height-matched to the locking nut, enabling quick and convenient disassembly and installation of the locking nut. It replaces the traditional method of disassembling and installing the locking nut by means of impact or other destructive methods, thereby improving the efficiency of fork replacement without damaging the locking nut, and saving more time and effort.

[0008] In the diagram, 1 is the handle; 2 is the locking seat; 3 is the locking tooth; 4 is the round hole; and 5 is the tail. Detailed Implementation

[0009] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0010] The outer circumferential wall of the lock nut has multiple notches spaced apart along the circumference, and these notches extend axially through the lock nut. Please refer to... Figure 1 The fork bearing locking wrench of this embodiment is used for disassembling and assembling the locking nut of the fork bearing. It is divided into a head at one end of the handle 1, a handle 1, and a tail 5 at the other end of the handle 1 along the length direction. The overall structure is symmetrical along the width direction. The head is used to cooperate with the locking nut and includes a toothed seat 2 and several teeth 3. The toothed seat 2 is smoothly connected to the handle 1 and the overall surface is flat. Several teeth 3 are set on one side end face of the toothed seat 2 according to the position distribution and shape of each notch. Each tooth 3 protrudes outward in a direction perpendicular to the end face of the toothed seat 2. The toothed seat 2 opens a circular hole 4 corresponding to the area enclosed by each tooth 3. The other end of the handle 1 is rounded and has a hole in the center as the tail 5. The center of symmetry of the circumferential array of each tooth 3, the center of the circular hole 4 of the head, and the center of the hole of the tail 5 are collinear.

[0011] In the specific implementation of the fork bearing locking wrench of this embodiment, the corresponding structural configuration also includes: Four notches distributed at equal intervals along the circumferential direction are formed on the outer peripheral wall of the lock nut, and four adapted clamping teeth 3 are correspondingly arranged on the clamping tooth seat 2. The special wrench for locking the fork bearing is correspondingly clamped into each notch through the four clamping teeth 3 along the axial direction of the lock nut, and the end face of the side of the clamping tooth seat 2 with the clamping teeth 3 is attached to or parallel to the axial end face of the lock nut.

[0012] The cross section of the notch on the lock nut is in a "匚" shape.

[0013] The head is in a circular ring shape, the inner hole of the circular ring serves as the circular hole 4, and the outer peripheral wall of the circular ring is axially flush with each clamping tooth 3.

[0014] The handle 1 is a strip-shaped plate structure.

[0015] When it is necessary to disassemble or install the fork bearing: First, hold the handle 1, align and insert each clamping tooth 3 on the wrench into each notch on the lock nut one by one, make the end face of the side of the clamping tooth seat 2 with the clamping teeth 3 parallel to the axial end face of the lock nut, and rotate the handle 1 clockwise or counterclockwise, so as to realize the quick installation or disassembly of the fork bearing.

[0016] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and purpose of the present utility model, and the scope of the present utility model is defined by the claims and their equivalents.
