Abstract

The invention relates to the field of a welding fixture and particularly discloses a clamping device. The clamping device comprises a supporting seat, a lower supporting plate, an upper supporting plate and a telescopic driving mechanism; the lower supporting plate is fixed on the supporting seat; one end of the lower supporting plate is rotatably connected with the upper supporting plate and the other end of the lower supporting plate is provided with a first lower clamping block; both ends of the telescopic driving mechanism are respectively connected with the lower supporting plate and the upper supporting plate; the upper supporting plate is provided with a spin chuck; the spin chuck is provided with a plurality of upper clamping blocks with different sizes; and the positions of the upper clamping blocks correspond to the positions of the first lower clamping blocks. According to the invention, universality of the clamping device on clamping and welding of parts with different heights; on the premise of ensuring part welding accuracy and part welding quality, the clamping device has a simple structure and is convenient to operate, the number of tools is reduced, an occupied space is small, influence on soldering plier operation is low, the welding repair operation is carried out a little, production cost is greatly reduced and production efficiency is effectively improved.

Description

technical field

[0001] The invention relates to the field of welding fixtures, in particular to a clamping device capable of freely switching between different clamping modes. Background technique

[0002] The welding fixture is an important process equipment that needs to be used in the welding process of the car body. The main function of the welding fixture is: the car body is composed of several parts with different sizes, shapes and thicknesses, and various parts need to be welded. The parts are connected to form the body, and the parts will have dimensional deviations during the welding process. In order to solve the dimensional deviations of the parts during the welding process, it is necessary to use welding fixtures for clamping and positioning during welding to ensure the welding accuracy of the parts.

[0003] For the existing welding fixtures, when two parts with different heights need to be clamped and welded sequentially, due to the limitation of the position o...
