Detailed Description

As shown in fig. 1 and 2, a clamping mechanism of a test platform of an automobile gearbox comprises a base 1, wherein frame bodies 3 which are opposite left and right are arranged on the base 1; the frame body 3 comprises a frame body 3I and a frame body 3 II, the frame body 3I is fixed on the base 1, the frame body 3 II is connected with the base 1 in a sliding mode, and the frame body 3 II is driven to change the distance between the frame body 3I and the frame body 3 II; be provided with wallboard one 41 on the support body 3 one, be provided with wallboard two on the support body 3 two, all set up reference column 7 on wallboard one 41 and the wallboard two, all be provided with the fixed column on wallboard one 41 and the wallboard two, the fixed gearbox box of a section of fixed column of reference column 7 cooperation wallboard two on the wallboard one 41, another section of gearbox box is fixed to the fixed column of reference column 7 cooperation wallboard one 41 on the wallboard two.

And the first wallboard 41 and the second wallboard are both provided with a second clamping assembly 8, and the second clamping assembly 8 is used for clamping the edge of the gearbox body.

The second clamping assembly 8 comprises an air cylinder 81, a connecting frame 82 and a clamping block 83 which are arranged on the wall plate, the air cylinder 81 is hinged to the clamping block 83, a block body of the clamping block 83 is hinged to the connecting frame 82, the connecting frame 82 is arranged on the second wall plate, and the front end of the connecting frame is located in front of the air cylinder 81.

The length of fixed column is greater than the length of reference column 7, and fixed column and wallboard can be dismantled and be connected.

The first wallboard 41 is fixedly arranged on the base 1, and the second wallboard moves along the base 1 under the driving of the frame body 3.

The working principle is as follows: fixed column on the installation wallboard 41, the gearbox box transports the assigned position at conveying mechanism, and reference column 7 on gearbox box and the wallboard 41 is aimed at, then 3 two movements along base 1 of drive support body, and 3 two drive wallboards of support body move towards wallboard 41, and the fixed column of wallboard two supports the gearbox box, and the cylinder 81 drive briquetting on the last wallboard 41 rotates with centre gripping gearbox box edge round the connecting block.
