Description

Technical Field

[0001] This utility model relates to the field of gear processing and welding technology, specifically a magnetic adsorption gear welding device. Background Technology

[0002] Common welding processes for gears include manual arc welding, gas shielded welding, submerged arc welding, and soldering. Different welding methods have their own characteristics and applicable scopes, and the selection must be based on factors such as the gear's material, shape, size, and usage conditions. Manual arc welding is suitable for repairing small gears, gas shielded welding is suitable for manufacturing large gears, submerged arc welding is suitable for gears with long weld seams, and soldering is suitable for reinforcing and repairing small gears.

[0003] For example, the existing technology CN118204585B describes a gear component processing and welding device and its working method. It uses a reduction motor to provide power to drive the gear teeth to rotate, and a welding torch to spray a laser beam that melts a straight welding wire at high temperature, causing the wire to adhere to the surface of the gear to be welded. A support column is used to slide a sliding rod, which in turn moves a height plate. The height plate secures the welding wire and the welding torch. A driving gear is used to drive the gear teeth to rotate. While this technical solution improves the welding structure and allows the gear to withstand greater torque after welding, it relies on a traditional screw and nut for gear fixation. This requires pre-positioning the gear on the clamp and manually rotating the screw. Even with electric drive, the screw rotation still takes time. Furthermore, the screw needs to be reset when releasing the gear, resulting in time wasted on mounting and dismounting. Additionally, this solution does not allow for rotation and repositioning of other gears after the gear is fixed; it requires releasing the clamp and repositioning. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a magnetic adsorption gear welding device, which has the advantages of quick and easy fixing of gears during welding and faster rotation and positioning of gears to be welded, thus solving the aforementioned technical problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a magnetic adsorption gear welding device, comprising a support platform, a welding gun mounted on the top surface of the support platform, the welding gun being connected to the support platform by a robotic arm, a groove extending from the top surface of the support platform, an electromagnetic generator mounted in the center of the groove, output ends for generating magnetic force after energization being provided at both ends of the electromagnetic generator, two vertically upward connecting rods slidably connected to the front and rear ends of the inner side of the groove, a limiting rod connected to the top of the connecting rod near the electromagnetic generator, and the inner sides of the two limiting rods penetrating and sharing a common threaded connection to an insert rod; A tray is provided at the center of the two limiting rods. The top surface of the tray is arc-shaped to place the gear, and the bottom of the tray is connected to a pillar installed on the top surface of the support platform to form a support.

[0006] As a preferred embodiment of this utility model, a slider is provided at the connection between the connecting rod and the slide groove, and an iron plate is installed between the slider and the output end of the electromagnetic generator.

[0007] As a preferred technical solution of this utility model, a limiting plate is also installed on the side of the limiting rod near the tray, and the center of the limiting plate is also provided with a through hole for the insertion rod to pass through.

[0008] As a preferred embodiment of this utility model, a support rod is further provided between the limiting plate and the connecting rod. The front and rear ends of the support rod are fixedly connected to the limiting plate and the connecting rod by welding, and the support rod is parallel to the limiting rod located above it.

[0009] As a preferred embodiment of this utility model, the support column connected to the bottom of the tray is an electric telescopic platform, and the output end of the electric telescopic platform is connected upward to the bottom surface of the tray, thereby controlling the height of the tray.

[0010] As a preferred technical solution of this utility model, the top surface of the tray is provided with protrusions on both sides that are consistent with the curvature of the top surface, and the two protrusions are used to initially clamp the gear placed on the top surface of the tray.

[0011] The robotic arm is existing technology. The gears in this application are welded using the technical solution published in CN115555722B, or the technical solution published in CN118204585B. Since this application does not improve the robotic arm and welding gun, its principle and effect will not be described in detail.

[0012] The electromagnetic generator is also existing technology. As described in the invention patent with publication number CN1015292B, it is directly set in the center of the inner side of the slide groove described in this application, so that the front and rear sections are electromagnetically attracted. In this application, the electromagnetic generator is just a mature device in the technical solution. This application has not improved its structure. The circuit control based on its body is also a mature technology. Therefore, its principle will not be described in detail in the subsequent specification. Furthermore, the electromagnet with model number 4WRE10W32-1X / 24K4 / M on the market can also be used as the electromagnetic generator of this application.

[0013] Compared with the prior art, this utility model provides a magnetic adsorption type gear welding device, which has the following beneficial effects: 1. This utility model uses an electromagnetic generator to generate electromagnets at its output ends on both sides, which in turn magnetically attract the connecting rod. After being attracted, the connecting rod moves toward the electromagnetic generator. At this time, the connecting rod drives the limiting rod to move toward the tray. Then, the two opposing limiting rods, along with the limiting plate, contact the gear placed on the tray, forming a clamp. This achieves the beneficial effect of quick and easy fixation of the gear during welding.

[0014] 2. This utility model uses a rod that penetrates the hollow part of the gear, thus forming a practical support. After the welding torch has finished welding a portion of the gear, the electromagnet generator only needs to be turned off. At this time, the two limit rods are released from their clamping position, and then the gear can be rotated to complete the adjustment. This achieves the beneficial effect of faster rotation and adjustment of the gear to be welded. Attached Figure Description

In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] Please see Figure 1-4 A magnetic adsorption gear welding device includes a support platform 1, a welding gun 101 mounted on the top surface of the support platform 1, and a mechanical arm connecting the welding gun 101 and the support platform 1. A groove 2 is started on the top surface of the support platform 1, and an electromagnetic generator 3 is installed in the center of the groove 2. Both ends of the electromagnetic generator 3 are provided with output ends for generating magnetic force after being energized. Two vertically upward connecting rods 4 are slidably connected to the front and rear ends of the inner side of the groove 2, respectively. The top of the connecting rods 4 is connected to the side of the electromagnetic generator 3. The two limiting rods 401 are connected to a common insertion rod 402 through the inner side of the two limiting rods 401. Further, the insertion rod 402 is only threaded to one limiting rod 401 and cannot be threaded to both rods at the same time. The other end of the insertion rod 402 is only inserted into the limiting rod and is not threaded. A tray 5 is provided at the center of the two limiting rods 401. The top surface of the tray 5 is arc-shaped to place the gear, and the bottom of the tray 5 is connected to the support column installed on the top surface of the support platform 1 to form support.

[0021] Furthermore, by connecting the electric telescopic table 7 to the bottom of the tray 5, the height of the tray 5 is controlled by the telescopic control of the output end of the electric telescopic table 7 to ensure that gears of different sizes can be penetrated by the insertion rod 402 and then clamped by the limiting plate 403.

[0022] Furthermore, in a structure not shown in the accompanying drawings of this application, the support column at the bottom of the tray 5, which is mounted on the top surface of the support platform 1, can also be a height-adjustable support column using a threaded connection.

[0023] Furthermore, when the bottom of the gear is placed on the top surface of the tray 5, it is initially limited by the protrusions on both sides of the tray 5 to ensure that it is in the center position of the top surface of the tray 5. Then, the insert rod 402 is passed through the interior of any one of the limiting rods 401, and then continues to pass through the limiting plate 403 and through the hole in the center of the gear, and then connects with another limiting rod 401. Finally, the insert rod 402 is rotated so that its thread connects with the thread provided on the inside of the limiting rod 401.

[0024] Furthermore, the electromagnetic generator 3 is activated so that the output ends on both sides form electromagnets, thereby magnetically attracting the connecting rod 4. In order to prevent the connecting rod 4 from being deformed due to direct attraction and movement, an iron plate 601 is installed on the side wall of the connecting rod 4. The iron plate 601 can expand the magnetic attraction area, and iron is the easiest material to be magnetically attracted, so the attraction is stronger.

[0025] Furthermore, after being attracted by the connecting rod 4, it moves towards the electromagnetic generator 3. At this time, the connecting rod 4 drives the limiting rod 401 to move towards the tray 5. At this time, the two opposing limiting rods 401, along with the limiting plate 403, contact the gear placed above the tray 5 to form a clamp.

[0026] Furthermore, the connection between the connecting rod 4 and the output end of the electromagnetic generator 3 is kept in place by a spring. Specifically, the output end of the electromagnetic generator 3 is connected to a spring, and then the spring contacts the iron plate 601 or the connecting rod 4. Since the spring structure is simple and the electromagnetic reset uses this structure, and since the insertion rod 402 passes through the hollow part of the gear, it forms actual support. After the welding torch 101 has finished welding a part of the gear, it is only necessary to turn off the electromagnetic generator 3. The spring on its output end will rebound and push back one end of the connecting rod. At this time, the two limit rods 401 are released from clamping, and then the gear can be rotated to complete the adjustment.

[0027] Furthermore, it is also possible to reset without using a spring, directly discard the spring, reverse the direction, and achieve the effect of releasing the clamp by relying solely on the relative sliding of the slider 6 and the groove 2.

[0028] When in use, the electromagnetic generator 3 is activated so that the output ends on both sides form electromagnets, which in turn magnetically attract the connecting rod 4. After being attracted, the connecting rod 4 moves toward the electromagnetic generator 3. At this time, the connecting rod 4 drives the limiting rod 401 to move toward the tray 5. At this time, the two opposing limiting rods 401, along with the limiting plate 403, contact the gear placed above the tray 5, forming a clamp.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
