Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical manufacturing, in particular to a rotatable welding jig. Background Art

[0002] Mechanical manufacturing refers to the production of power machinery, lifting and transportation machinery, chemical machinery, textile machinery, machine tools, tools, instruments, meters and other mechanical equipment, such as hardware, plastic parts and electronic boards;

[0003] During the manufacturing process of electronic boards, external welding equipment is required to weld the solder legs of electronic components to the electronic boards. To improve the stability when welding the electronic boards and electronic components, workers confine the electronic boards to welding jigs. The components of the welding jigs include: clamping components, base plates, supports, and bolts.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. In the use of existing welding jigs, the position of the welded parts on the carrier plate is limited by adjusting the positions of two or more clamping plates and locking the positions of the clamping plates by rotating bolts, which effectively prevents the welded parts from shifting during the welding process and makes it more convenient for workers to operate external welding equipment to weld the welded parts. However, due to the large number of clamping plates and the independent existence of the clamping plates, the workers need to adjust the positions of the clamping plates one by one, which makes the operation steps cumbersome and increases the workload of the workers.

[0006] 2. During use, the existing welding jig is locked to the mounting surface by bolts to prevent the existing welding jig from shaking during use. This improves the stability of the existing welding jig during operation and is beneficial to the welding process of the welded parts. However, it requires the workers to move their positions and perform welding processes on different positions of the welded parts, which increases the amount of movement of the workers and reduces the practicality of the existing welding jig.

[0007] To this end, we provide a rotatable welding fixture to solve the above problems. Utility Model Content

[0008] The purpose of the utility model is to provide a rotatable welding jig, which solves the problems of complicated operation steps for limiting the position of welding parts and low practicality of existing welding jigs by providing a clamping component and a rotating component.

[0009] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0010] The utility model relates to a rotatable welding jig, which comprises a carrier plate. A guide groove is formed on the side wall of the carrier plate.

[0011] The utility model is further arranged such that support blocks connected to the peripheral side wall of the placement plate are connected to the side wall of the carrier plate, and the number of the support blocks is four.

[0012] The utility model is further arranged such that sliding blocks are symmetrically and fixedly connected to the lower surface of the clamping plate, sliding grooves are symmetrically formed on the carrier plate, and the sliding blocks are slidably connected to the sliding grooves.

[0013] The utility model is further arranged such that there are two guide blocks, the number of the guide blocks is equal to the number of the guide grooves, and both the guide blocks and the guide grooves are in a middle shape.

[0014] The utility model is further arranged such that a guide rail is formed on the inner side wall of the installation frame, and a sliding rod fixedly connected to the side wall of the toothed plate is slidably connected to the guide rail.

[0016] The utility model is further arranged such that an installation component is arranged below the circular gear. A substrate in the installation component is arranged below the circular gear. Supports are connected to the four corners of the lower surface of the substrate, and bolts are threadedly connected to the supports in an annular array.

[0017] The utility model is further arranged such that a convex rod is rotatably connected to the inside of an interference fit damping bearing on the substrate, the convex rod is connected to the middle of the lower surface of the circular gear, and the outer diameter of the circular gear is two-thirds of the outer diameter of the placement plate.

[0018] The utility model has the following beneficial effects:

[0019] 1. The utility model realizes the winding and unwinding of the connecting rope by setting a clamping assembly, rotating the rotating rod, and rotating the connecting shaft. When the connecting rope is wound, the two clamps clamp the welding parts on the carrier plate. When the connecting rope is unwound, the two clamps release the welding parts.
