Description

Technical Field

[0001] This utility model relates to a fixture, specifically a novel spot welding fixture. Background Technology

[0002] Spot welding is a welding method that uses a cylindrical electrode to form a weld point between the contact surfaces of two overlapping workpieces. During spot welding, pressure is first applied to make the workpieces come into close contact, and then current is applied. Under the action of resistance heating, the contact area of ​​the workpieces melts and forms a weld point after cooling. Existing fixtures have certain limitations in their clamping range and are not suitable for spot welding various sheet metal parts of different sizes. In addition, the adjustment method of existing fixtures is manual, which makes the adjustment operation time-consuming, labor-intensive and inefficient. Therefore, a new type of spot welding fixture needs to be designed to solve this problem. Utility Model Content

[0003] The purpose of this utility model is to provide a novel spot welding fixture to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A novel spot welding fixture includes a support plate, on which vertical plates are symmetrically mounted. A rotating shaft is rotatably mounted on the vertical plates, and a mounting plate is mounted on the rotating shaft. Mounting slots are formed on the mounting plates, and mounting blocks are symmetrically slidably mounted in the slots. Connecting plates are symmetrically mounted on one side of each mounting block. A rotating rod is disposed between the connecting plates and rotatably connected to the connecting plates. A connecting rod is fixedly connected to the rotating rod, and a clamping plate is connected to one end of the connecting rod. A telescopic component is mounted on each mounting block, and an adjusting block is connected to the end of the telescopic component away from the mounting block. A driving rod is hinged to the adjusting block, and the end of the driving rod away from the adjusting block is hinged to the connecting rod. A driving assembly is mounted on the mounting plate and connected to the mounting blocks. An adjusting assembly is mounted on the support plate and connected to the mounting plate.

[0005] As a further embodiment of this utility model: the driving assembly includes a driving component, which is mounted on a mounting plate. A driving shaft is mounted on the output end of the driving component. The end of the driving shaft away from the driving component extends into the mounting groove. Threaded rods are symmetrically arranged in the mounting groove. One end of the threaded rod is rotatably connected to the side wall of the mounting groove, and the other end is connected to a connecting unit. The end of the connecting unit away from the threaded rod is connected to the driving shaft. The threaded rod and the mounting block are connected by threads.

[0006] As a further embodiment of this utility model: the adjustment component includes an adjustment groove, a telescopic component is installed on the side wall of the adjustment groove, a drive block is connected to the end of the telescopic component away from the side wall of the adjustment groove, an adjustment rod is hinged on the drive block, and the end of the adjustment rod away from the drive block is hinged to the mounting plate.

[0007] As a further embodiment of this utility model: the telescopic component is an electric telescopic rod.

[0008] As a further embodiment of this invention, the driving component is a stepper motor.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: When it is necessary to weld a workpiece, it needs to be fixed first. The distance between the clamping plates needs to be adjusted according to the size of the workpiece to be fixed. The driving component drives the drive shaft to rotate, and the rotation of the drive shaft drives the threaded rod to rotate through the connecting unit. The rotation of the threaded rod, under the action of the thread, drives the connected mounting block to move. The movement of the mounting block can thus drive the clamping plate on one side of the connecting plate to move. By adjusting the longitudinal distance between the clamping plates, workpieces of different lengths can be fixed. After the position of the clamping plates is adjusted, the workpiece is placed between the clamping plates, and the extension... The shrinking component moves the adjusting block, which in turn drives the connecting rod at one end of the drive rod to rotate. The connecting rod then drives the clamping plate at one end to rotate around the rotating rod. The clamping plates rotate in opposite directions around the rotating rod, thus clamping and fixing the workpiece placed in the middle part, improving the stability of subsequent spot welding of the workpiece. When it is necessary to adjust the angle of the workpiece, the telescopic component moves the drive block connected to it. The movement of the drive block drives the mounting plate at one end to rotate through the adjusting rod. The mounting plate rotates around the rotating shaft at a certain angle, allowing the workpiece to be rotated to the required angle, which facilitates the processing of the workpiece by the operator and improves the practicality of the device.

[0016] In this embodiment, when the workpiece needs to be welded, it must first be fixed. The drive component moves the mounting block 10 connected to it. The movement of the mounting block 10 moves the clamping plate 19 on one side of the connecting plate 13.

[0017] Furthermore, the telescopic component 14 can be an electric telescopic rod or an electric push rod, etc., which will not be described in detail here.

[0018] Furthermore, the end face of the clamp 19 uses a low-hardness elastic material (such as silicone pad, TPU soft pad, polyurethane foam) as the contact surface to provide a larger contact area and reduce contact pressure.

[0019] As an embodiment of this utility model, the driving assembly includes a driving component 6, which is mounted on the mounting plate 5. A driving shaft 7 is mounted on the output end of the driving component 6. The end of the driving shaft 7 away from the driving component 6 extends into the mounting groove.

[0020] In this embodiment, when fixing the workpiece, the distance between the clamping plates 19 needs to be adjusted according to the size of the workpiece to be fixed. The driving component 6 drives the driving shaft 7 to rotate. The rotation of the driving shaft 7 drives the threaded rod 9 to rotate through the connecting unit 8.

[0024] In this embodiment, when it is necessary to adjust the angle position of the workpiece to be spot welded, the telescopic component drives the drive block 3 connected to it to move. The movement of the drive block 3 drives the mounting plate 5 at one end to rotate through the adjusting rod 4. The mounting plate 5 rotates around the rotating shaft 12 at a certain angle. After the workpiece is rotated to the required angle, it is convenient for the workers to process the workpiece, thus improving the practicality of the device.

[0025] Furthermore, the telescopic component can be an electric telescopic rod or an electric push rod, etc., which will not be described in detail here.

[0026] The working principle of this utility model is as follows: When welding a workpiece is required, it needs to be fixed first. The distance between the clamping plates 19 needs to be adjusted according to the size of the workpiece to be fixed. The driving component 6 drives the driving shaft 7 to rotate. The rotation of the driving shaft 7 drives the threaded rod 9 to rotate through the connecting unit 8. The rotation of the threaded rod 9, under the action of the thread, drives the connected mounting block 10 to move. The movement of the mounting block 10 can thus drive the clamping plate 19 on one side of the connecting plate 13 to move. By adjusting the longitudinal distance between the clamping plates 19, workpieces of different lengths can be fixed. After the position of the clamping plates 19 is adjusted, the workpiece is placed between the clamping plates 19, and the telescopic component 14 drives the adjustment...
