Abstract

The invention relates to a positioning and locking mechanism comprising an L-shaped connecting seat, a limiting block, an operation handle, a U-shaped adapting block, a connecting rod mechanism, a U-shaped connecting seat, a moving lock tongue, moving rotating shafts, a lock hook, a positioning pin, a positioning bearing block, a fixed rotating shaft, a connecting seat, a limiting shaft, an S base plane and a spring. According to the technical scheme, the structure is simple, machining is convenient, precision is reliable, production and manufacturing are easy, and the manufacturing cost is reduced to a great extent. The positioning and locking mechanism is suitable for positioning a vehicle body plate with a positioning hole being not parallel to a vehicle body line, and the situation that a piece to be measured falls due to the gravity action, and thus the efficiency and testing precision of a testing tool are influenced is avoided. A locking mechanism body is arranged, thus accurate positioning and locking can be achieved, and the accuracy of the testing result of the testing tool is improved. The positioning and locking mechanism is convenient to use, site operation of a worker is facilitated, and the testing efficiency and the testing precision of the testing tool can be improved.

Description

technical field [0001] The invention belongs to the technical field of inspection fixture accessories, in particular to a positioning and locking mechanism. Background technique [0002] In the debugging stage of new products, the improvement of the accuracy of the body-in-white is an important and arduous task, and it is also a key indicator of product mass production, while the inspection tool is an important means to identify and verify the process problems of the body, and is the key to problem decomposition. Effective measures from sub-assembly to single piece are an important means of guarantee for product precision analysis and improvement. [0003] Before the part clamping and inspection can start, the part needs to be positioned first. The parts can be accurately positioned on the inspection fixture through the positioning pin to ensure that there is no looseness during the inspection operation. Due to the diversification of the car body structure, the positioning...
