Abstract
Description
Technical Field
[0001] This utility model relates to the field of bushing disassembly, specifically to a labor-saving and convenient bushing disassembly device. Background Technology
[0002] When the post-spinning guide roller bushing needs to be disassembled, it usually requires the cooperation of skilled workers, or a long period of work for them, which is time-consuming and labor-intensive. Furthermore, when using a shaft to remove the worn bushing, the front end of the shaft inevitably suffers wear and tear, requiring the shaft to be polished, which takes 10 minutes. Utility Model Content
[0003] The purpose of this invention is to provide a bushing disassembly device that solves the problems of difficult and inefficient bushing disassembly.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A bushing disassembly device includes an operating lever with a hook-shaped front end and a control handle at the rear end; a fixed hammer and a transmission component are provided in the middle of the operating lever, with the fixed hammer located on the side near the control handle and the transmission component movably located on the side far from the control handle.
[0006] Furthermore, the operating lever is integrally formed, and the control handle is triangular.
[0007] Furthermore, the fixed hammer is fixedly connected to the operating rod via a connecting seat.
[0008] Furthermore, the transmission component includes a first transmission hammer, a second transmission hammer, and a connecting rod. The first transmission hammer is connected to the second transmission hammer via the connecting rod. The operating rod is provided with multiple sliding rails, and the connecting rod is provided with a slider that matches the sliding rails.
[0009] Furthermore, the bending angle of the hook-shaped portion ranges from 60° to 90°.
[0010] Furthermore, there are four sliding tracks, which are evenly distributed around the center of the operating lever; there are four sliders, which are evenly distributed around the connecting rod.
[0011] Compared with the prior art, this utility model has the following advantages and beneficial effects:
[0012] This invention involves hooking the hook-shaped part onto the bushing. A technician controls the handle to keep the operating lever in a roughly horizontal position. Then, the technician controls the transmission component to move in a first direction. The transmission component strikes a fixed hammer, which transmits the force to the bushing. The bushing, under the action of the transmission component, also moves in the first direction, ultimately allowing for quick removal of the bushing without damaging the shaft. This invention achieves the goal of quickly removing the bushing from the shaft, improving work efficiency and ensuring component safety. Attached Figure Description

[0018] like Figure 1 and Figure 2 As shown, a bushing removal device includes an operating lever 1, with a hook-shaped portion 11 at the front end and a control handle 12 at the rear end. A fixing hammer 2 and a transmission component 3 are located in the middle of the operating lever 1. The fixing hammer 2 is positioned near the control handle 12, and the transmission component 3 is movably positioned away from the control handle 12. A technician operates the control handle 12 to fix the operating lever 1, causing the hook-shaped portion 11 to hook onto the bushing. Then, the transmission component 3 moves back and forth. Even if the transmission component 3 strikes the fixing hammer 2, the hammer 2 applies a backward force to the operating lever 1. The hook-shaped portion 11 transmits this backward force to the bushing, ultimately removing the bushing from the shaft. This not only improves the efficiency of bushing removal but also ensures the integrity of the shaft, preventing damage and eliminating the need for post-removal maintenance.
[0019] The operating lever 1 is integrally formed, and the control handle 12 is triangular. Compared with a straight lever, the triangular control handle 12 is more helpful for technicians to fix the operating lever 1 and improve the efficiency of removing the bushing.
[0020] The fixed hammer 2 is fixedly connected to the operating rod 1 via a connecting seat. The fixed hammer 2 is disc-shaped, and direct welding is not feasible. By adding a connecting seat, the connecting seat is first fixed to the operating rod 1, and then the fixed hammer 2 is welded to the connecting seat, so that the fixed hammer 2 is fixedly connected to the operating rod 1, which facilitates the transmission of internal force.
[0021] like Figures 3 to 5 As shown, the transmission component 3 includes a first transmission hammer 31, a second transmission hammer 32, and a connecting rod 33. The first transmission hammer 31 is connected to the second transmission hammer 32 via the connecting rod 33. The operating rod 1 is provided with multiple sliding rails 14, and the connecting rod 33 is provided with sliders 34 adapted to the sliding rails 14. A technician holds the connecting rod 33, causing the first transmission hammer 31 to strike the fixed hammer 2, resulting in an outward pulling force on the bushing from the operating rod 1. Adding the sliding rails 14 and the adapted sliders 34 ensures that the transmission component 3 can only move along the axial direction of the operating rod 1 and will not rotate. Without the sliding rails 14 and sliders 34, the force applied by the technician to the connecting rod 33 would inevitably cause the transmission component 3 to rotate relative to the operating rod 1, resulting in a loss of some of the force exerted by the technician. With the addition of the sliding rails 14 and the adapted sliders 34, almost all of the force exerted by the technician is applied to the first transmission hammer 31 striking the fixed hammer 2, accelerating the removal speed of the bushing and improving work efficiency.
[0022] The bending angle of the hook-shaped part 11 is in the range of 60° to 90°, which allows the hook-shaped part 11 to hook more stably onto the bushing. If the angle is obtuse, the bushing cannot be removed. If the angle is too small, the stability of the fit between the hook-shaped part 11 and the bushing will be reduced.
[0023] There are four sliding tracks 14, evenly distributed circumferentially along the middle of the operating rod 1; there are four sliders 34, evenly distributed circumferentially along the connecting rod 33. Each sliding track 14 corresponds one-to-one with a connecting rod 33, which extends the service life of the sliders 34 on the connecting rod 33 and also ensures that the connecting rod 33 can move axially along the operating rod 1.
[0024] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
