Technical Field

[0001] The utility model relates to the technical field of automobile maintenance equipment, and particularly relates to a clamping mechanism for automobile parts suitable for spot welding in a small space. Background Technique

[0002] During the processing or maintenance of an automobile, it is common to weld and fix some automobile parts. When welding, it is necessary to fix the parts. Among them, the clamping device for automobile parts is a commonly used device for fixing and clamping automobile parts, which can ensure the stability and accuracy of the parts during the welding and assembly process, and can improve production efficiency and product quality.

[0003] However, the existing clamping devices for automobile parts are generally fixed types, that is, they can only clamp and fix the parts, and cannot adjust themselves. This makes it difficult to place the parts in a suitable position well when facing small-space operations. Their flexibility is poor and it is difficult to be applicable to small-space operations.

[0004] In order to solve this technical problem, the utility model proposes a clamping mechanism for automobile parts suitable for spot welding in a small space. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a clamping mechanism for automobile parts suitable for spot welding in a small space, which can effectively solve the problems mentioned in the background technique.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A clamping mechanism for automobile parts suitable for spot welding in a small space includes a clamping jaw. A rotating head is arranged at the side end of the clamping jaw. A rotating tube is rotatably connected to the side end of the rotating head. A first servo motor is arranged inside the rotating tube. A fixing plate is arranged at the side end of the rotating tube. A second servo motor is connected inside the fixing plate. A moving square tube is arranged at the side end of the fixing plate. A threaded rod is threadedly connected inside the moving square tube. A fixed sleeve is slidably connected to the outer end of the moving square tube. A fixed tube is connected to the side end of the fixed sleeve. A third servo motor is connected inside the fixed tube. A handle is arranged at the side end of the fixed tube.

[0008] Preferably, anti-slip grooves are formed inside the clamping jaw. A threaded block is connected between the clamping jaws. A threaded groove is formed inside the threaded block. A fourth servo motor is connected inside the rotating head.

[0009] Preferably, the driving end of the fourth servo motor is connected with a bolt rod. The bolt rod is located at the side end of the rotating head. The bolt rod is threadedly connected inside the threaded block. The driving end of the first servo motor is connected to the rotating head.

[0010] Preferably, the second servo motor is located inside the rotating tube. The driving end of the second servo motor is connected to the rotating tube. A threaded groove is provided inside the moving square tube, and a square groove is provided inside the fixed sleeve.

[0011] Preferably, the driving end of the third servo motor is connected to the threaded rod. Anti-slip grooves are provided at the outer end of the grip. Control buttons are provided at the outer end of the grip. The control buttons are respectively connected to each servo motor through wires. A battery is provided inside the grip.

[0012] Preferably, a fixed ring is connected to the outer end of the rotating head. A lighting lamp is provided inside the fixed ring. The lighting lamp is located on both sides of the clamping jaw and irradiates light towards the clamping jaw. The lighting lamp is connected to the control button through a wire.

[0013] Preferably, a connecting plate is connected to the side end of the grip. Electromagnets are connected between the connecting plates. The electromagnets are connected to the control buttons through wires.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] In the utility model, by providing a rotating head, the first servo motor can drive the rotating head to rotate, so as to adjust the angle of the clamping jaw itself. By providing a rotating tube, the second servo motor can drive the rotating tube to rotate, so as to adjust the overall angle of the rotating tube and the clamping jaw. By providing a moving square tube, a threaded rod, and a fixed sleeve, the third servo motor can drive the threaded rod to rotate. The rotation of the threaded rod acts on the moving square tube, and the moving square tube cannot rotate under the action of the fixed sleeve, so as to push the rotating tube to move, thereby being able to adjust the overall position of the rotating tube and the clamping jaw. With this device, the direction of the clamping jaw can be adjusted at multiple angles and the length can be extended, so that the clamping jaw can adapt to a wider range of working scenarios, making it easier for the clamping jaw to grasp and place objects at different angles and positions, improving work efficiency and precision, and having high flexibility and strong applicability.

[0016] In the utility model, by providing lighting lamps on both sides of the rotating head, it can illuminate the object clamped by the clamping jaw, so as to facilitate the staff to observe and thus facilitate welding. By providing an electromagnet, when it is energized, it will generate a magnetic force. After determining the position of the clamping jaw, the device can be fixed by adsorbing the electromagnet on the metal plate of the vehicle, so as to fix the object clamped by the clamping jaw, thereby liberating the hand of the staff for holding the grip, and thus facilitating the staff to carry out welding work and effectively improving work efficiency.
