Description

Technical Field

[0001] This utility model relates to the field of riveting machine technology, and in particular to a watch gear riveting machine. Background Technology

[0002] Pneumatic riveting machines utilize stamping equipment and specialized connecting molds to perform an instantaneous high-pressure processing procedure. Based on the cold extrusion deformation of the sheet metal itself, a stress-free internal inlaid dot with a certain tensile and shear strength is formed, which can connect two or more layers of sheets of different materials and thicknesses. Currently, in watch manufacturing, especially during the riveting process of watch hands, workers need to use pneumatic riveting machines to fix the needle core into the needle hole of the watch hand, thereby completing the initial assembly of the watch hand.

[0003] By comparing a pneumatic riveting machine for watch processing with patent publication number CN221493932U, this solution utilizes the cooperation of a magnetic block, adapter block, return spring, traction gear plate, gap gear, drive component, and transmission shaft to uniformly feed the watch hands inside the material box, effectively improving overall processing efficiency. The cooperation of the adapter shaft, interceptor block, torsion spring, and limit shaft can limit the movement of the fed watch hands, preventing them from returning to the material box due to magnetic block reset. However, when riveting the gears, manual placement of the gears on the upper end of the watch hands is required. This placement necessitates aligning the gears and watch hands on the same axis, increasing the positioning time between the gears and watch hands and reducing the efficiency of gear riveting.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-4 As shown, a watch gear riveting machine includes a base plate 100 and a riveting structure for riveting watch gears, the riveting structure being located above the base plate 100.

[0026] In this embodiment: the riveting structure includes a support base 201 disposed above the base plate 100. The support base 201 is connected to the base plate 100 by bolts. A lifting seat 202 is slidably installed on the front side of the support base 201. A hydraulic cylinder 203 is provided between the top of the lifting seat 202 and the support base 201. A riveting head 204 is installed at the lower end of the lifting seat 202. A fixing column 215 is provided below the riveting head 204. A feeding platform 218 is provided at the top of the fixing column 215. A feeding hole 216 is opened at the top of the feeding platform 218. The fixing column 215 is fixedly connected to the base plate 100. A material holding frame 217 is provided on one side of the fixing column 215. A feeding platform is fixed at the upper end of the material holding frame 217. A positioning structure for positioning the placement position of the gear is provided between the fixing column 215 and the riveting head 204.

[0027] The positioning structure includes two slide rails 205 arranged in front of the support base 201, with a sliding plate 207 slidably installed inside the slide rails 205. A cylinder 206 is provided between the sliding plate 207 and the slide rails 205. A lifting frame 208 is slidably installed inside the sliding plate 207. A compression spring is connected between the lifting frame 208 and the sliding plate 207. Two moving plates 210 arranged in the front-back direction are slidably installed between the two lifting frames 208. An electric push rod 209 is provided between the moving plate 210 and the lifting frame 208. A support plate 211 is fixed at the bottom of the moving plate 210. Clamping plates 212 are rotatably installed on both the front and rear sides of the support plate 211. The upper end of the clamping plate 212 is an arc-shaped surface. A torsion spring 214 is connected between the rotating end of the clamping plate 212 and the support plate 211. A baffle 213 is fixed in the middle of the support plate 211. The bottom end of the clamping plate 212 is made of rubber. The lower end of the riveting head 204 is provided with a pressing structure for moving the clamped gear downward.

[0028] The pressing structure includes a mounting sleeve 219 at the bottom of the riveting head 204. The mounting sleeve 219 is connected to the riveting head 204 by bolts. Two pressing plates 220 are fixed at the bottom of the mounting sleeve 219, which are symmetrically arranged in the front-back direction. The pressing plates 220 are made of silicone. Before riveting the gear, the riveting structure first positions the gear through the positioning structure, so that the gear and the pointer are on the same axis. This reduces the time for workers to position the gear and the pointer, reduces the workload of workers in positioning the gear, ensures the quality of riveting between the gear and the pointer, and improves the efficiency of gear riveting.

[0029] Working principle: First, the dial indicator needle is placed in the feeding hole 216 at the upper end of the feeding platform 218 above the fixed column 215. Then, the cylinder 206 is activated to move the two sliding plates 207 to the front and rear sides of the fixed column 215, and to move the two moving plates 210 to the top of the fixed column 215. Then, the gear is placed between the four clamping plates 212. The electric push rods 209 on both sides are activated to move the two moving plates 210 towards each other, and to move the clamping plates 212 on both sides towards each other. The gear is clamped and fixed by the four clamping plates 212. At the same time, the four clamping plates 212 are used to position the gear when clamping it, thereby reducing the time for workers to position the gear and the dial indicator needle, reducing the workload of workers in positioning the gear, ensuring the quality of riveting between the gear and the dial indicator needle, improving the efficiency of gear riveting, and ensuring that the gear and the dial indicator needle are on the same axis.

[0030] Then, the hydraulic cylinder 203 is activated to move the lifting seat 202 downward, which in turn moves the riveting head 204 downward, and then moves the pressing plate 220 downward. The pressing plate 220 applies downward pressure to the moving plate 210, causing the lifting frame 208 to move downward, which in turn moves the gear in the clamping position downward, so that the center hole of the gear is fitted onto the upper end of the dial indicator. Then, the downward-moving riveting head 204 is used to rivet the dial indicator, so that the dial indicator and the gear are riveted together, completing the riveting operation of the gear. Then, the hydraulic cylinder 203 is driven to move the riveting head 204 upward, so that the pressing plate 220 loses its pressure on the moving plate 210. The lifting frame 208 moves upward and resets under the release force of the compression spring, which in turn moves the support plate 211 upward, which in turn moves the riveted gear upward. The workers remove the gear and place it on the unloading platform next to it, and then it falls into the collection frame 217 for collection.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
