Description

Technical Field

[0001] The utility model relates to the technical field of fixture installation, in particular to a special fixture installation component for the rotating shaft of a welding clamp Background Technique

[0002] The welding clamp is an important tool for fixing and positioning workpieces during the welding process. It plays a crucial role in the welding process. Welding fixtures play an important role in fields such as automobile production lines. Their application not only improves the automation level of welding production but also greatly improves the working conditions of workers. The welding fixture replaces the heavy physical work such as positioning, clamping, and workpiece flipping during traditional manual assembly of parts in the form of a mechanical device, reducing the labor intensity of workers

[0003] When the rotating shaft of the welding clamp is driven by a cylinder, it is generally limited by a fixed-size installation and positioning structure, which can only limit the rotating shaft and rotating plate of the clamp of one size, and the applicable range is small. Therefore, a special fixture installation component for the rotating shaft of the welding clamp is needed to solve the above problems Content of the Utility Model

[0004] The purpose of the utility model is to provide a special fixture installation component for the rotating shaft of a welding clamp to solve the problem raised in the above background technique: when the rotating shaft of the welding clamp is driven by a cylinder, it is generally limited by a fixed-size installation and positioning structure, which can only limit the rotating shaft and rotating plate of the clamp of one size, and the applicable range is small

[0005] To achieve the above purpose, the utility model provides the following technical scheme: a special fixture installation component for the rotating shaft of a welding clamp, including a protective housing. A clamping device rotating shaft is inserted between the tops on one side of the protective housing. Both ends of the clamping device rotating shaft extend to the outside of the protective housing. A clamping device rotating connecting plate is fixedly connected between both ends of the clamping device rotating shaft. A driving component is fixedly installed inside the protective housing. The output end of the driving component is in transmission connection with the clamping device rotating shaft. Limiting components are connected to both sides of the protective housing near the clamping device rotating connecting plate

[0006] Preferably, the driving component includes a driving cylinder, and the output end on the upper surface of the driving cylinder is fixedly connected with a driving toothed plate

[0007] Preferably, a driving gear is fixedly connected to the center of the clamping device rotating shaft, and the driving toothed plate is meshed and connected to one side of the driving gear

[0008] Preferably, the limiting component includes a limiting connecting plate. On one side of the upper surface of the limiting connecting plate away from the clamping device rotating shaft, a limiting screw tube is fixedly connected. On the other side of the upper surface of the limiting connecting plate, a limiting sliding groove is provided. A limiting screw rod is in threaded connection inside the limiting screw tube.

[0009] Preferably, a T-shaped slider is slidably connected inside the limiting sliding groove. On the upper surface of the T-shaped slider, a positioning pressing plate is fixedly connected.

[0010] Preferably, the positioning pressing plate is directly opposite to the position of the rotating connecting plate of the clamping device. One end of the limiting screw rod is in contact with the positioning pressing plate. The other end of the limiting screw rod is fixedly connected with an adjusting turning handle. The purpose of such a setting is that: by setting the adjusting turning handle, the limiting screw rod can be driven to displace. Through the limiting screw rod, the positioning pressing plate can be pushed to displace. By making the positioning pressing plate close to and limit the rotating connecting plate of the clamping device and the clamping device rotating shaft, it is avoided that when the driving gear is driven by the driving tooth plate, the clamping device rotating shaft has a horizontal offset, which affects the offset of the meshing part between the driving tooth plate and the driving gear and affects the limiting effect. The adjustable positioning pressing plate can adapt to clamping device rotating connecting plates and clamping device rotating shafts of more sizes, and the adaptation range is larger.

[0011] The technical effects and advantages of the present utility model:

[0012] (1) In this device, by setting the adjusting turning handle, the limiting screw rod can be driven to displace. Through the limiting screw rod, the positioning pressing plate can be pushed to displace. By making the positioning pressing plate close to and limit the rotating connecting plate of the clamping device and the clamping device rotating shaft, it is avoided that when the driving gear is driven by the driving tooth plate, the clamping device rotating shaft has a horizontal offset, which affects the offset of the meshing part between the driving tooth plate and the driving gear and affects the limiting effect. The adjustable positioning pressing plate can adapt to clamping device rotating connecting plates and clamping device rotating shafts of more sizes, and the adaptation range is larger, solving the problem that the rotating shaft of the welding clamping device is generally limited by a fixed-size installation and positioning structure when driven by a cylinder, and it can only limit the rotating shaft and rotating plate of a clamping device of one size, and the applicable range is small.

Through the driving gear, the clamping device rotating shaft and the rotating connecting plate of the clamping device are driven to rotate. Through the rotating connecting plate of the clamping device, the workpiece to be welded is pressed and positioned. Brief Description of the Drawings
