Problems solved by technology

The main structural form is realized through the expansion and contraction of the double guide rod cylinder, or the fixture structure is fixed on the two slide rails, and the switching is realized by sliding, and the flexibility is poor; at the same time, the above two solutions can only be applied to two types of vehicles. The speed of model replacement has limitations; secondly, the positioning accuracy is insufficient, and an additional limit structure is required, resulting in an oversized and complex structure of the overall positioning structure, which affects welding operations

Embodiment Construction

[0016] Combine below Figure 1-Figure 11 The present invention is discussed in further detail.

[0017] A clamp switching device, comprising a mounting plate 10, the clamping mechanism 50 for clamping the vehicle body is arranged at intervals on the peripheral surface of the mounting plate 10, the mounting plate 10 is coaxially fixed with a rotating shaft 21, and the rotating shaft 21 is rotated and arranged on a fixed On the seat 30 , a positioning pin 41 is also arranged on the fixed seat 30 , and when the positioning pin 41 slides along its own axial direction, it is inserted into and locked with the positioning hole 12 provided on the mounting plate 10 or separated and unlocked. The axial direction of the locating pin 41 and the axial direction of the rotating shaft 21 may be parallel or non-parallel, as long as the locking and unlocking of the mounting disk 10 can be realized, the axial direction of the locating pin 41 is preferably parallel to the rotating shaft 21. Dur...

Abstract

The purpose of the present invention is to provide a clamp switching device that can realize the collinear production of multiple models and enhance the flexibility of the welding main line. The peripheral surface of the mounting plate is provided with a clamping mechanism for clamping the vehicle body at intervals. The mounting plate is coaxially fixed with a rotating shaft, the rotating shaft is rotatably arranged on the fixed seat, and the fixed seat is also provided with a positioning pin. In normal use, the locating pin is inserted into the locating hole to limit the rotation of the mounting plate, and the clamping mechanism clamps the vehicle body. If the vehicle model needs to be switched, the external force is inserted into the locating hole to push the locating pin out of the locating hole and separate. The restraint of the plate is released, and then the external force rotates, and the mounting plate rotates along with it to the position of the clamping mechanism corresponding to the switching model. .

Description

technical field [0001] The invention relates to the technical field of automobile automatic production lines, and specifically designs a fixture switching device. Background technique [0002] During the planning process of the welding production line of the automobile OEM, the requirements for the flexible production capacity of the production line are getting higher and higher, and improving the commonality of the main line fixtures of the welding production line is the key to ensuring the flexible production of multiple models in the welding production line. If you want to realize the flexible mixed line production of multiple models, you need to ensure the automatic switching of different welding fixtures to meet the needs of collinear production of different models. However, the fixture design of the welding production line of each car factory basically adopts a fixed method, that is, the fixture is distributed on the welding line, and each clamping point is fixed, and ...
