Description

Technical Field

[0001] The present application relates to the technical field of roller polishing tools, and in particular, to an auxiliary tool for polishing a transfer roller. Background Art

[0002] In the process of automobile production, many automobile parts need to be made by stamping process. In the process of mass stamping production, the conveyor rollers in the blanking die will wear out. The wear of the conveyor rollers will reduce the surface finish and cause scratches, dents, bulging and other defects on the sheet metal. Therefore, it is necessary to regularly polish the conveyor rollers to improve their finish. In the prior art, the polishing process of the conveyor roller is to first disassemble the conveyor roller, then fix the conveyor roller on the bench vise, polish it with sandpaper, and then install the conveyor roller back to its original position. The process is cumbersome and time-consuming. The polishing process of a single conveyor roller takes 5 minutes. In addition, the stamping workshop has multiple sets of blanking dies, each set of blanking dies has at least 40 conveyor rollers, and the most have 200 conveyor rollers. As a result, the polishing work of the conveyor rollers in the entire workshop takes up a lot of working time and has low work efficiency. Utility Model Content

[0004] Through the above technical scheme, when polishing the conveyor roller, there is no need to remove the conveyor roller from the blanking die. The circumferential surface of the driving roller of the auxiliary tool of the present application is directly attached to the circumferential surface of the conveyor roller, and the driving member is used to drive the driving roller to rotate through the connecting rod, thereby driving the conveyor roller to rotate in situ on its connecting shaft. The staff can then hold the sandpaper to polish the rotating conveyor roller, so that the working time of polishing a single conveyor roller is reduced to 1 minute, which greatly improves the work efficiency; and, since the small diameter of the driving roller makes it difficult to drive the conveyor roller, and because the space at the conveyor roller of the blanking die is limited, the diameter of the driving roller is limited to 20 to 50 mm in the present application, which is helpful to drive the conveyor roller to rotate stably and adapt to the size of the space at the conveyor roller; and, the driving roller is made of polyurethane or rubber, so that the driving roller is soft and wear-resistant, and the surface of the conveyor roller is prevented from being scratched.

[0005] Preferably, the dimension of the driving roller along its axial direction is larger than the dimension of the conveying roller along its axial direction, which ensures that the circumference of the conveying roller can fit with the circumference of the driving roller, and helps the driving roller to drive the conveying roller to rotate.

[0006] Preferably, the circumferential surface of the driving roller is provided with anti-skid grooves, which help to increase the friction between the circumferential surface of the driving roller and the circumferential surface of the conveying roller, thereby improving the stability of the driving roller driving the conveying roller to rotate.

[0007] Preferably, the anti-slip pattern is a plurality of convex rings, which are distributed on the circumference of the driving roller along the axial direction of the driving roller; the inner diameter of the convex ring is equal to the diameter of the driving roller, the convex ring is sleeved on the driving roller, and the convex ring and the driving roller are integrally formed.

[0008] Preferably, a blind hole is formed at the end of the driving roller along its axial direction, the size and shape of the blind hole match the size and shape of the first end of the connecting rod, and the first end of the connecting rod is inserted into the blind hole.

[0009] Preferably, the circumferential surface of the connecting rod is bonded to the inner wall of the blind hole.

[0010] Preferably, the driving member is a handheld grinder or a handheld electric drill, the second end of the connecting rod matches the clamping portion of the handheld grinder or the clamping portion of the handheld electric drill, and the clamping portion of the handheld grinder or the clamping portion of the handheld electric drill is clamped on the second end of the connecting rod, so that the auxiliary tool of the present application is portable.

[0011] The utility model provides an auxiliary tool for polishing a transmission roller, which has the following beneficial effects:

[0012] By designing the driving roller and the connecting rod thereon to be connected to a handheld grinder or a handheld electric drill, the handheld grinder or the handheld electric drill drives the driving roller to rotate, and when polishing the transmission roller, there is no need to remove the transmission roller from the blanking die. The peripheral surface of the driving roller of the auxiliary tool of the present application is directly attached to the peripheral surface of the transmission roller to drive the transmission roller to rotate. The staff can then polish the rotating transmission roller with sandpaper, which greatly shortens the working time of polishing a single transmission roller, thereby improving work efficiency; the driving roller is made of polyurethane or rubber, which makes the driving roller soft and wear-resistant to prevent scratches on the surface of the transmission roller, and anti-skid patterns are designed on the surface of the driving roller, which helps to improve the stability of the transmission roller driven by the driving roller. The auxiliary tool of the present application has a simple structure, low cost, and easy operation. BRIEF DESCRIPTION OF THE DRAWINGS
