Description

Technical Field

[0001] This utility model relates to the field of elevator buffer technology, and in particular to a quick-change tooling for welding elevator buffers. Background Technology

[0002] Elevator buffers are a key component in the upstream of the elevator industry chain. During the production process, the housing of the elevator buffer needs to be welded to the base and the top cover respectively.

[0003] The applicant has discovered at least the following technical problems in the prior art: In the existing production process, due to the different structures of the base and the top cover, two different welding machines are required. One machine is used to weld the base, which adopts an integrated drive mechanism and base tooling, and the other machine is used to weld the top cover, which adopts an integrated drive mechanism and top cover tooling. The two different welding machines result in low production efficiency and high cost. Utility Model Content

[0004] The purpose of this utility model is to provide a quick-change tooling for welding elevator buffers, thereby solving the technical problem in the prior art where two different welding machines are required during the production process of welding the elevator buffer shell to the base and the top cover separately—one for welding the base and one for welding the top cover—resulting in low production efficiency and high cost. The various technical effects of the preferred technical solutions provided by this utility model are detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A quick-change welding fixture for elevator buffers includes a drive mechanism unit, a top cover fixture, and a base fixture. The drive mechanism unit includes a drive mechanism body and a connecting base connected to each other. The connecting base can be detachably connected to either the top cover fixture or the base fixture.

[0007] Preferably, it further includes a quick connector, and the connecting base is provided with a first quick connector, which can be detachably connected to either the top cover fixture or the base fixture via the quick connector.

[0008] Preferably, the top cover fixture is provided with a second quick-connect part, and the first quick-connect part and the second quick-connect part can be detachably connected through the quick-connect part.

[0009] Preferably, the base fixture is provided with a third quick-connect part, and the first quick-connect part and the third quick-connect part can be detachably connected through the quick-connect part.

[0010] Preferably, the first quick-connect part includes a first positioning pin hole, which is formed on the connecting base, and the quick-connect part is a positioning pin.

[0011] Preferably, the second quick-connect part includes a second positioning pin hole, which is formed on the top cover fixture, and the positioning pin can be connected with the corresponding first positioning pin hole and second positioning pin hole.

[0012] Preferably, the third quick-connect part includes a third positioning pin hole, which is formed on the base fixture, and the positioning pin can be connected with the corresponding first positioning pin hole and the third positioning pin hole.

[0013] Preferably, the number of the first positioning pin holes is several, and the several first positioning pin holes are evenly distributed along the circumference. The number of the second positioning pin holes is the same as that of the first positioning pin holes and their positions correspond to each other. The number of the third positioning pin holes is the same as that of the first positioning pin holes and their positions correspond to each other.

[0014] The beneficial effects of this utility model are as follows: By adding a connecting base to the drive mechanism body, the connecting base can be detachably connected to either the top cover fixture or the base fixture. If the base needs to be welded, the operator can disassemble the top cover fixture, then install the base fixture and the connecting base, and then place the base on the base fixture. If the top cover needs to be welded, the operator can disassemble the base fixture, then install the top cover fixture and the connecting base, and then place the top cover on the top cover fixture.

[0015] Therefore, when needed, the drive mechanism unit can quickly and conveniently connect to either the base or the top cover fixture or the base fixture, thereby enabling rapid switching between top cover welding operations and base welding operations. The elevator buffer welding quick switching fixture only needs to use the same drive mechanism unit to quickly switch between the top cover fixture and the base fixture, meeting production needs, effectively reducing production costs, and improving production efficiency.
