Description

Technical Field

[0001] This utility model relates to the field of watch manufacturing technology, specifically a pneumatic riveting machine for watch manufacturing. Background Technology

[0002] Pneumatic riveting machines, also known as riveting presses or riveting machines, are devices used for nail-free riveting on cold-rolled metal sheets. They are commonly used in sheet metal processing, offering good forming properties, aesthetically pleasing appearance, and convenient and quick operation. Pneumatic riveting machines utilize stamping equipment and specialized connecting dies to perform a high-pressure processing process in an instant. Based on the cold extrusion deformation of the sheet material itself, a stress-free internal inlaid dot with certain tensile and shear strength is formed, thus connecting two or more layers of sheets of different materials and thicknesses.

[0003] Currently, during watch manufacturing, especially during the riveting process of watch hands, workers need to use a pneumatic riveting machine to fix the needle core into the needle hole of the watch hand to complete the initial assembly of the watch hand. However, existing pneumatic riveting machines are generally only responsible for conveying the needle core to the bottom of the pressing end. For the watch hand, workers need to manually put it through the needle hole onto the needle core before normal riveting can be carried out. However, this process is not only time-consuming and laborious, but also increases the danger of the work process. Utility Model Content

[0004] The purpose of this invention is to provide a pneumatic riveting machine for watchmaking to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic riveting machine for watch processing, including a mounting frame, a riveting table fixedly mounted on the outside of the mounting frame, an intermittent feeding mechanism on the top of the riveting table, and a pneumatic riveting mechanism on the top of the mounting frame.

[0006] The intermittent feeding mechanism includes a conveying component and a pressure-resistant component, with the pressure-resistant component located on the side closest to the conveying component.

[0007] The conveying assembly includes a mounting box, which is fixedly mounted on the top of the riveting table. A motor is fixedly mounted on the outside of the mounting box. A wheel is fixedly mounted on the side of the mounting box near the motor, and a belt drives the wheel to the motor.

A limiting plate is fixedly installed on the top of the sliding rod, and a spring is fixedly installed between the limiting plate and the riveting table. A stamping column is fixedly installed on the top of the riveting table near the limiting plate.

[0009] Preferably, the support frame is U-shaped, there are two sets, and they are symmetrically distributed inside the mounting box with the motor as the axis.

[0010] Preferably, the springs are in two sets and are symmetrically distributed on the top of the riveting table with the stamping column as the axis.

[0011] Preferably, the connecting plates are located inside the mounting box, and there are four sets of them, which are symmetrically distributed inside the mounting box.

[0012] Preferably, the pneumatic riveting mechanism includes a cylinder, which is fixedly installed on the top of the mounting frame. The top of the cylinder has a cylinder port, and the top of the mounting frame has a sliding groove on the side near the cylinder. A riveting plate is fixedly installed at one end of the cylinder extending into the inner side of the mounting frame, and a riveting head is fixedly installed at the bottom of the riveting plate.

[0013] Preferably, there are two sets of sliding grooves, and the sliding grooves are slidably connected to the rivet plate.

[0014] Compared with the prior art, this utility model provides a pneumatic riveting machine for watchmaking, which has the following advantages:

[0015] This pneumatic riveting machine for watch processing uses an intermittent feeding mechanism. The motor drives the push rod to feed the watch hands intermittently, reducing the inconvenience of manual feeding, protecting worker safety, and reducing labor costs. The limit plate allows the watch hands to fall at the needle core, facilitating subsequent stamping, avoiding damage to the limit plate, enabling sustainable use, and reducing material costs.

[0016] This pneumatic riveting machine for watch processing uses a pneumatic riveting mechanism to open the cylinder, which, under the weight of the riveting plate, presses down on the parts inside the limiting plate, increasing the downward pressure. This makes it easier to assemble the parts during riveting, enhancing the riveting effect and increasing the success rate of riveting parts. Attached Figure Description

[0026] Please see Figure 1-4 This utility model provides a technical solution: a pneumatic riveting machine for watch processing, including a mounting frame 1, a riveting table 2 fixedly mounted on the outside of the mounting frame 1, an intermittent feeding mechanism 3 provided on the top of the riveting table 2, and a pneumatic riveting mechanism 4 provided on the top of the mounting frame 1.

[0027] The intermittent feeding mechanism 3 includes a conveying component 31 and a pressure-resistant component 32, with the pressure-resistant component 32 located on the side close to the conveying component 31.

[0028] The conveying assembly 31 includes a mounting box 311, which is fixedly mounted on the top of the riveting table 2. A motor 312 is fixedly mounted on the outside of the mounting box 311. A wheel 313 is fixedly mounted on the side of the mounting box 311 near the motor 312, and a belt 317 is connected between the wheel 313 and the motor 312. A connecting plate 314 is fixedly mounted on one end of the wheel 313 extending into the inside of the mounting box 311. A support frame 315 is rotatably mounted on the outside of the connecting plate 314, and a push rod 316 is fixedly mounted on the outside of the support frame 315.

[0029] Furthermore, the anti-compression component 32 includes a sliding rod 321, which is fixedly installed on the top of the riveting table 2 near the mounting box 311. A limiting plate 323 is fixedly installed on the top of the sliding rod 321. A spring 322 is fixedly installed between the limiting plate 323 and the riveting table 2. A stamping column 324 is fixedly installed on the top of the riveting table 2 near the limiting plate 323 to protect the limiting plate 323 from being crushed during riveting.

[0030] Furthermore, the support frame 315 has a U-shaped appearance, consists of two sets, and is symmetrically distributed inside the mounting box 311 with the motor 312 as the axis, which facilitates the realization of multiple sets of transmission.

[0031] Furthermore, there are two sets of springs 322, which are symmetrically distributed on the top of the riveting table 2 with the stamping column 324 as the axis, so as to facilitate the next stamping and help reset.

[0032] Furthermore, the connecting plates 314 are located inside the mounting box 311, and there are four sets of them, which are symmetrically distributed inside the mounting box 311 to facilitate the up-down and back-down movement of the support frame 315. Example

[0033] Please see Figure 5 Furthermore, in conjunction with Embodiment 1, the pneumatic riveting mechanism 4 includes a cylinder 41, which is fixedly installed on the top of the mounting bracket 1. The top of the cylinder 41 has a cylinder port 45. The top of the mounting bracket 1 has a sliding groove 42 on the side near the cylinder 41. A riveting plate 43 is fixedly installed on one end of the cylinder 41 extending to the inner side of the mounting bracket 1. A riveting head 44 is fixedly installed on the bottom of the riveting plate 43 to increase the riveting pressure and enhance the riveting effect.

[0034] Furthermore, there are two sets of sliding grooves 42, and the sliding grooves 42 are slidably connected to the riveting plate 43, which facilitates limiting the riveting position.

[0035] In actual operation, when this device is used, the parts to be riveted are placed on the mounting box 311, and then the motor 312 is turned on, causing the motor 312 to drive the rotating wheel 313 to rotate via the belt 317. When the rotating wheel 313 rotates, the connecting plate 314 inside the mounting box 311 drives the support frame 315 to move back and forth and up and down. When the support frame 315 moves, it drives the push rod 316 to push, causing the parts on the mounting box 311 to move under the push, avoiding manual loading and reducing labor costs. When the parts fall into the limiting plate 323 by the push, the opening... The cylinder 41 is activated, allowing air to enter through the cylinder port 45. This causes the cylinder 41 to press against the riveting plate 43 at one end inside the mounting bracket 1, causing the riveting plate 43 to slide on the slide groove 42. When the riveting plate 43 presses downward, it drives the riveting head 44 to rivet the parts inside the limiting plate 323. This causes the sliding rod 321 below the limiting plate 323 to be pressed and slide downward inside the riveting table 2. When the limiting plate 323 is pressed against the stamping column 324, the riveting action is applied to the stamping column 324, completing the riveting of the parts and preventing damage to the limiting plate 323. Afterward, the parts are reset by the elastic force of the spring 322.
