Description

Technical Field

[0001] This utility model relates to the field of elevator component manufacturing equipment technology, specifically to a welding fixture for elevator components. Background Technology

[0002] Elevator components include a part called the trigger mechanism base, which consists of a rectangular plate-shaped base and two wing plates perpendicular to the base, with coaxial holes on the wing plates. During manufacturing, the wing plates need to be welded to the base, ensuring that the two wing plates are parallel and perpendicular to the base, and that the holes on the wing plates are aligned to keep their axes in a straight line.

[0003] Existing welding fixtures for this type of part can only ensure parallelism but cannot guarantee the perpendicularity of the wing plate to the base. Therefore, there is an urgent need for a welding fixture specifically designed to clamp this part. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is:

[0005] 1. A welding fixture is provided for the base part of the trigger mechanism, which can simultaneously ensure that the wing plates are parallel to each other, the wing plates and the base are perpendicular to each other, and the axes of the holes on the wing plates are aligned after clamping.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including a base plate, a back plate and at least two side plates, wherein the upper surface of the base plate is a first positioning surface, the front surface of the back plate is a second positioning surface, and the side surface of the side plates is a third positioning surface;

[0007] The first positioning surface is perpendicular to the second positioning surface, the second positioning surface is perpendicular to the third positioning surface, and the third positioning surface is perpendicular to the first positioning surface.

[0008] A gap for inserting components is provided between the first positioning surface and the side plate;

[0009] The base plate is connected to the back plate.

[0010] In use, the side of the wing plate is aligned with the third positioning surface, and the back of the wing plate is aligned with the second positioning surface. The base is inserted into the gap between the side plate and the first positioning surface, with the bottom of the base aligned with the first positioning surface and the top surface of the base aligned with the bottom of the wing plate. The joint between the top surface of the base and the bottom of the wing plate is the welded joint. This solution achieves the positioning of the wing plate and the base through the cooperation of the three positioning surfaces. After the wing plate and the base are placed on the welding fixture, it can simultaneously ensure that the wing plates are parallel to each other, the wing plates and the base are perpendicular to each other, and the axes of the holes on the wing plates are aligned.

[0011] Optionally, the side plate is provided with positioning holes.

[0012] The positions of the positioning holes correspond to the positions of the holes on the wing plate. During welding operations, positioning pins can be inserted into the positioning holes to ensure that the holes on the wing plate are coaxial.

[0013] Optionally, it may also include fasteners that mate with the side plate.

[0014] Optionally, the fastener includes a fixing plate, a positioning plate, and a fastening bolt. The positioning plate is fixedly connected to the fixing plate, and the fastening bolt passes through the fixing plate. A gap is left between the fastening bolt and the positioning plate for placing the side plate and components.

[0015] This solution uses fastener design to press the wing plate onto the third positioning surface, further enhancing the clamping stability of the tooling.

[0016] Optionally, a positioning block is also provided at the connection between the base plate and the back plate.

[0017] The positioning block corresponds to the groove shape on the base, and it is mainly used to position the base relative to the wing plate in the horizontal direction.

[0018] Optionally, the rear surface of the back plate is further provided with reinforcing ribs.

[0019] Optionally, a pad is bolted to the upper surface of the base plate.

[0020] The design of the pad block allows for adjustment of the gap width between the first positioning surface and the side plate, providing space for component insertion.

[0021] Optionally, the base plate and the back plate are connected by bolts.

[0022] The beneficial technical effects of this utility model are: by cooperating with the three positioning surfaces, the positioning of the wing plate and the base is achieved. After the wing plate and the base are placed on the welding fixture, it can simultaneously ensure that the wing plates are parallel to each other, the wing plates and the base are perpendicular to each other, and the axes of the holes on the wing plates are aligned.
