Description

Technical Field

[0001] The utility model belongs to the technical field of automobile door lock processing, in particular to a fixing fixture for automobile door lock processing. Background Art

[0002] Car door lock processing usually requires welding. During the manufacturing process of car door locks, some parts may need to be connected and fixed by welding. For example, some structural parts of the door lock may need to be welded to ensure strength and stability; some electrical connection parts may also need welding to ensure good conductivity and reliability. Welding technology can provide a firm connection to adapt to the various forces and environmental conditions that the door lock faces during use;

[0003] A Chinese patent with publication number "CN219649014U" discloses a welding workpiece fixing fixture, which includes a base, wherein the interior of the base is fixedly connected to motor 1, the output end of the motor 1 is fixedly connected to rotating rod 1, the side surface of rotating rod 1 is fixedly connected to a cam, and the upper surface of the cam is movably connected to connecting rod 1; a protective device, wherein the interior of the protective device is movably connected to connecting rod 2, and the end of connecting rod 2 away from the protective device is movably connected to a cross plate, and the lower surface of the cross plate is fixedly connected to a ball, and the ball is connected through the protective device, and the end of the ball away from the protective device is fixedly connected to connecting rod 1; a clamp, wherein the upper surface of the clamp is connected through a threaded rod, and the end of the threaded rod away from the clamp is fixedly connected to connecting rod 3, and the end of the threaded rod close to the clamp is fixedly connected to an extrusion plate. Through the above structure, the placement angle of the clamped welding workpiece can be adjusted to meet the welding requirements of different welding workpieces;

[0004] Although the above-mentioned clamp can play a good positioning role during use, it is not convenient to flexibly adjust the processed workpiece for lateral displacement adjustment during welding during specific applications. If the welding of the door lock workpiece requires a large range of linear welding processing, its fixed design obviously cannot perform multi-position welding on the top of the door lock workpiece. It can be seen that it has certain defects and shortcomings and needs to be improved. Utility Model Content

[0024] The clamping mechanism 7 includes a first motor 71, which is fixedly mounted on the top of the base plate 5. A receiving seat 72 is fixedly mounted on the output end of the first motor 71. A slide groove 73 is provided in the middle of the receiving seat 72. A slide plate 74 is slidably connected to the inner side of the slide groove 73. A screw rod 75 is rotatably connected to the inside of the receiving seat 72. The threads of the two ends of the screw rod 75 are rotated in opposite directions.

A second motor 77 is fixedly mounted in the middle of one side of the receiving seat 72. The output of the second motor 77 The outlet end is fixedly connected to one end of the screw rod 75. In the clamping mechanism 7, the first motor 71 can drive the receiving seat 72 to rotate to flexibly adjust the lock. The second motor 77 drives the screw rod 75 to make the slide plate 74 and the top clamping frame 76 displace each other to stably clamp the lock. The clamping frame 76 is cleverly designed to effectively prevent the lock from falling out, thereby ensuring the stability and accuracy of the clamping. The rotating mechanism 3 and the adjustment mechanism 6 can allow the base plate 5 and the components thereon to flexibly rotate and displace on the top plate 4, realize multi-directional and multi-angle adjustment, and improve the adaptability and convenience of lock processing.

The gear ring 32 is rotatably connected to the outer side of the top plate 4. The top of the gear ring 32 is fixedly connected to the bottom of the adjustment mechanism 6. The gear 34 is meshed with the gear ring 32.

This design makes it possible to conveniently perform all-round rotation operation on the lock during processing to meet different processing requirements. Moreover, the components are closely connected and cooperate well, thereby ensuring the stability and reliability of the rotation process.

At the same time, the second bracket 710 is attached to the top of the top plate 4 through the bottom ball 711. The ball 711 at the bottom of the second bracket 710 assists in rolling, which can support the receiving seat 72 while maintaining the stability of the base plate 5 rotating on the top of the top plate 4, thereby improving the overall stability of the device for clamping the lock;
