Rapid fixing mechanism for bolt welding

Abstract

The invention provides a rapid fixing mechanism for bolt welding. The rapid fixing mechanism comprises an outer sleeve, an inner sleeve and a compression nut. The inner sleeve is arranged in the outer sleeve, the outer sleeve extends out from the upper portion of the inner sleeve and is provided with a clamping groove, a handle is arranged on the clamping groove and penetrates the outer sleeve and the inner sleeve, the compression nut is arranged at the upper end of the inner sleeve, a fixing bolt is arranged at the lower end of the outer sleeve, a compression rod is arranged in the inner sleeve and is connected with the compression nut, a magnet is arranged at the lower end of the compression rod, and an ejector rod is arranged at lower end of the magnet. During welding, the rapid fixing mechanism is fixed to a fixture and pressure is exerted to the compression nut by an air cylinder or manual compression device to complete rapid fixing, positioning and welding of a bolt on an automotive welding part. The rapid fixing mechanism is high in work efficiency, convenient and rapid to mount and demount and capable of protecting threads from damage.

Description

technical field [0001] The invention relates to the field of auto parts welding, in particular to a fast fixing mechanism with welding bolts. Background technique [0002] Usually, a kind of welding bolt (bolt specification is generally M6 and M8) for fixing parts (such as thread bracket, lock bracket, etc.) should be welded on some welding parts of the car. The disadvantages of this method are slow work efficiency, inconvenient loading and unloading, and fragile threads. Therefore, in order to overcome the disadvantages of the above-mentioned method, it is particularly important to provide a welded bolt mechanism that is convenient and fast in loading and unloading, and saves time and effort. Contents of the invention [0003] In order to overcome the above-mentioned problems, the present invention provides a fast fixing mechanism for welding bolts, which is convenient and quick to assemble and disassemble, and saves time and effort. [0004] In order to solve the above ...
