Abstract
Description
Technical Field
[0001] This invention belongs to the field of capacity formation technology in the lithium battery production process, specifically relating to a replacement structure for a linear bearing in a charging and discharging device. Background Technology
[0002] In the production process of lithium batteries, capacity formation is a crucial step. The equipment used in this step needs to lift the battery trays using a lifting motion, which is guided by linear bearings.
[0003] During the lifting and lowering operation of the mechanism, the equipment may become eccentric due to asynchronous cylinder adjustment, welding of the mechanism frame, or deviations in the fly surface. This causes the linear bearing to be constantly subjected to radial force when the equipment moves up and down. After prolonged operation, the linear bearing may burst. Since the linear bearing cannot be replaced after it is damaged, the entire equipment will become paralyzed. Summary of the Invention
[0004] To solve the above-mentioned technical problems, the present invention provides a replacement structure for a linear bearing in a charging and discharging device. After the linear bearing is damaged, it is removed to the top of the guide shaft and fixed to avoid the travel position of the mechanism. The replacement structure of the present invention is installed in place using its original mounting holes. The guide shaft is clamped by two guide wheels to replace the linear bearing.
[0005] The technical solution adopted in this invention is:
[0006] A linear bearing replacement structure for a charging and discharging device is characterized in that it includes a guide shaft (1) to be fixed, a guide wheel (5) and a clamping device, wherein the guide wheel (5) is provided on both sides of the guide shaft (1), namely the first guide wheel and the second guide wheel;
[0007] The clamping device includes a guide fixing plate (2), a fixed base plate (3), a guide wheel pull plate (4), and a guide wheel pressure plate (6). The fixed base plate (3) is set on the original linear bearing mounting hole. The guide wheel pressure plates (6) are symmetrically arranged on both sides of the fixed plate (3). The guide wheel pull plate (4) is arranged on the side of the guide wheel pressure plate (6) close to the guide shaft (1), and the guide fixing plate (2) is arranged on the side of the guide wheel pressure plate (6) away from the guide shaft (1). The guide fixing block (2) is located above the fixed base plate (3). The two ends of the first guide wheel are set on the guide wheel pressure plates (6) on both sides, and the two ends of the second guide wheel are set on the guide wheel pull plates (4) on both sides. The guide wheel pressure plate is moved forward by the guide fixing block until the first guide wheel is pressed against the guide shaft. The guide wheel pull plate is pulled towards the guide shaft through the hole on the guide wheel pressure plate until the second guide wheel is pressed against the guide shaft.
[0008] Furthermore, the guide fixing block (2) has a first through hole for fixing at both ends. The guide wheel pressure plate (6) has a first fixing hole for cooperating with the first through hole on the side away from the guide shaft (1). One end of the first fixing member passes through the first through hole and the first fixing hole to realize the connection between the guide fixing block (2) and the guide wheel pressure plate (6).
[0009] Furthermore, the guide wheel pressure plate (6) and the guide wheel pull plate (4) are respectively provided with a second through hole and a second fixing hole on the side opposite to each other. One end of the second fixing member passes through the first through hole and the second fixing hole to realize the connection between the guide wheel pressure plate (6) and the guide wheel pull plate (4).
[0010] Furthermore, a groove is provided on the side of the guide wheel pressure plate (6) near the guide wheel pull plate (4), and an extension section is provided on the side of the guide wheel pull plate (4) near the guide wheel pressure plate (6), the extension section being adapted to the groove.
[0011] The technical concept of this invention is as follows: This invention replaces a damaged linear bearing by setting guide wheels and guide shafts at the original mounting holes of the linear bearing, and clamping the guide shaft with two guide wheels.
[0012] Compared with the prior art, the beneficial effects of the present invention are reflected in:
[0013] This invention uses two guide wheels to clamp the guide shaft, thus replacing the linear bearing and solving the problem of equipment malfunction and inoperability caused by linear bearing failure. Attached Figure Description
