Abstract

The invention discloses a height adjustment device for a pressure machine test platform. The height adjustment device comprises the test platform and further comprises a driving mechanism and a height adjustment mechanism. The driving mechanism comprises a servo motor and a worm gear transmission unit. The height adjustment mechanism comprises adjusting sliding blocks and a base which are sequentially located on the lower side of the test platform, the test platform is in horizontal contact with the adjusting sliding blocks, the two adjusting sliding blocks are arranged on the two sides of the base, and the adjusting sliding blocks on the two sides of the base form inclined plane matching with the base. A support is fixed to the base, a transmission shaft matched with the worm gear transmission unit to rotate is arranged in a space defined by the base, the support, the adjusting sliding blocks and the test platform, the transmission shaft is in contact with the adjusting sliding blocks on the two sides of the base, and in the rotating process, the distance between the adjusting sliding blocks on the two sides of the base is adjusted.

Description

technical field

[0001] The invention belongs to the technical field of press machinery, and in particular relates to a height adjustment device for a test platform of a press. Background technique

[0002] Bottom dead center precision is an important technical index of high-speed precision presses, which directly affects the precision of punched products and the service life of molds. The important index to measure the high-speed press is not only the static accuracy index, but also its dynamic accuracy. Bottom dead point accuracy is an important dynamic accuracy, a key performance index of high-speed presses, and an important index for evaluating product technical level and manufacturing level.

[0003] Traditional high-speed precision presses mostly use a crank-slider mechanism, relying on the motor to drive the worm gear mechanism, thereby driving the threaded pair to rotate, and realizing the adjustment of the height of the slider. The threaded pair bears periodic punch...
