Abstract
Description
Technical Field
[0001] This invention relates to the field of watch manufacturing technology, and more specifically, to a watch hand shaft polishing device. Background Technology
[0002] In the field of watch manufacturing and repair, the polishing quality of the end face of the hand shaft (the miniature metal shaft used to fix the hour and minute hands) directly affects the smoothness of the hand assembly and the appearance quality. Traditional polishing processes have the following significant drawbacks: they rely on manual operation, requiring workers to hold the hand shaft and polish it on a rotating grinding wheel or sandpaper, resulting in low efficiency (less than 100 pieces polished per day). Furthermore, long-term operation can easily lead to fatigue, causing problems such as tilting of the polished surface and inconsistent dimensions. Uneven force applied manually or fluctuations in the contact surface pressure of fixed polishing equipment can also result in uneven shaft surfaces.
[0003] Therefore, it is necessary to provide a watch hand shaft polishing device to solve the above problems. Utility Model Content
[0004] Based on the aforementioned problems in the existing technology, the purpose of this application is to provide a watch hand shaft polishing device that achieves uniform force on the hand shaft surface and prevents excessive wear.
[0005] The technical solution adopted by this application to solve its technical problem is: a watch hand shaft polishing device, including a toolbox, a workbench fixedly installed at the upper end of the toolbox, a protective plate fixedly installed at the side end of the workbench, a rotating motor fixedly installed on the upper side of the protective plate, the drive end of the rotating motor passing through the protective plate, the drive end of the rotating motor being rotatably connected to a polishing belt turntable, a polishing belt being wound on the outer surface of the polishing belt turntable, and a clamping assembly fixedly installed at the side end of the protective plate.
[0006] Furthermore, the clamping assembly includes a telescopic cylinder, which is fixedly installed on the side end of the guard plate. A piston rod is fixedly installed at the front end of the telescopic cylinder, and a push block is fixedly connected to the front end of the piston rod.
[0007] Furthermore, the clamping assembly also includes a slide rod, which is fixedly installed at the front end of the telescopic cylinder. A slider is slidably connected to the upper end of the slide rod, and a bracket is fixedly installed at the upper end of the slider. The push block is fixedly connected to the lower end of the bracket.
[0008] Furthermore, rollers are connected to the bearings on both sides of the upper end of the bracket, and an auxiliary rod is fixedly installed at the lower end of the roller. A placement plate is fixedly installed at the upper end of the auxiliary rod, and a placement hole is opened at the upper end of the placement plate.
[0009] Furthermore, a rotating wheel is connected to the side bearing of the guard plate, and the polishing belt moves on the rotating wheel.
[0010] The beneficial effects of this utility model are: starting the telescopic cylinder pushes the piston rod at the front end to extend forward, the piston rod extends forward and drives the push block to move forward, the push block moves forward and drives the bracket to move forward, the bracket slides forward along the slide rod with the help of the slider, and then the bracket will drive the placement plate and the dial indicator shaft to move to the lower end of the polishing belt, thereby determining the polishing position.

[0015] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0016] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.
[0017] In this invention, unless otherwise stated, the orientations used, such as "up" and "down," generally refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" generally refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this invention.
[0018] like Figure 1-2As shown, this application provides a watch hand shaft polishing device, including a toolbox 1, a workbench 2 fixedly installed on the upper end of the toolbox 1, a protective plate 3 fixedly installed on the side end of the workbench 2, a rotating motor 4 fixedly installed on the upper side of the protective plate 3, the driving end of the rotating motor 4 passing through the protective plate 3, the driving end of the rotating motor 4 being rotatably connected to a polishing belt turntable 5, a polishing belt 6 being wound on the outer surface of the polishing belt turntable 5, and a clamping assembly fixedly installed on the side end of the protective plate 3.
[0019] The clamping assembly includes a telescopic cylinder 8, which is fixedly installed on the side of the guard plate 3. A piston rod 9 is fixedly installed at the front end of the telescopic cylinder 8, and a push block 11 is fixedly connected to the front end of the piston rod 9.
[0020] The clamping assembly also includes a slide bar 10, which is fixedly installed at the front end of the telescopic cylinder 8. A slider 12 is slidably connected to the upper end of the slide bar 10, and a bracket 13 is fixedly installed at the upper end of the slider 12. The push block 11 is fixedly connected to the lower end of the bracket 13.
[0021] The upper ends of the bracket 13 are connected to bearings on both sides to rollers 14, and auxiliary rods are fixedly installed at the lower ends of rollers 14. A placement plate is fixedly installed at the upper end of the auxiliary rod, and a placement hole 15 is opened at the upper end of the placement plate.
[0022] The side bearing of the guard plate 3 is connected to the rotating wheel 7, and the polishing belt 6 is attached to the rotating wheel 7 and moves.
[0023] Specifically, the staff places the dial indicator shaft to be polished parallel into the placement hole 15 on the placement plate. The two ends of the dial indicator shaft will be engaged in the roller 14. Then, the telescopic cylinder 8 is activated to push the piston rod 9 at the front end to extend forward. The piston rod 9 extends forward and drives the push block 11 to move forward. The push block 11 moves forward and drives the bracket 13 to move forward. The bracket 13 slides forward along the slide rod 10 with the help of the slider 12. Then the bracket 13 will drive the placement plate and the dial indicator shaft to the lower end of the polishing belt 6, thereby determining the polishing position.
[0024] When the dial indicator shaft moves to the lower end of the polishing belt 6, the operator turns on the rotating motor 4 to drive the polishing belt turntable 5 to rotate. The rotation of the polishing belt turntable 5 drives the polishing belt 6 to move cyclically along the rotating wheel 7 to rub and polish the surface of the dial indicator shaft. After polishing is completed, the rotating motor 4 is turned off, the telescopic cylinder 8 is controlled to retract the piston rod 9, and the bracket 13 and the placement plate are reset, and the polished dial indicator shaft is taken out.
