A connection structure between a hydraulic assembly machine and a special fixture

Abstract

The invention discloses a connecting structure for a hydraulic assembly machine and a special clamp. The connecting structure comprises the hydraulic assembly machine, a linkage clamp and the special clamp, wherein the hydraulic assembly machine comprises an upper hydraulic assembly machine moving plate and a hydraulic assembly machine substrate, the special clamp comprises an upper die plate and a lower die plate, and the linkage clamp comprises an upper linkage clamp linkage unit and a lower linkage clamp positioning plate. The upper linkage clamp linkage unit is in rigid connection with the bottom surface of the upper hydraulic assembly machine moving plate, the upper die plate is connected to the bottom of the upper linkage clamp linkage unit in a sleeved mode, the lower linkage clamp positioning plate is in rigid connection with the top surface of the hydraulic assembly machine substrate, the lower die plate and the lower linkage clamp positioning plate are fixed coaxially, and a coaxial positioning mechanism is arranged between the upper linkage clamp linkage unit and the lower linkage clamp positioning plate. The connecting structure has the advantages of being capable of reducing the time for installing the special clamp on the hydraulic assembly machine to improve production efficiency.

Description

technical field [0001] The invention relates to a connection structure between a hydraulic assembly machine and a special fixture. Background technique [0002] At present, the connection structure between the hydraulic assembly machine and the special fixture widely used in China mainly adopts the connection mechanism of briquetting and pressing iron. [0003] like figure 1 As shown, the hydraulic assembly machine hydraulic cylinder 11 is mounted on the bottom surface of the hydraulic assembly machine moving plate 12, and the bottom surface of the hydraulic assembly machine moving plate 12 is provided with an upper T-shaped groove 121. The upper template 21 of the special fixture 2 is fixed with the upper moving plate 12 of the hydraulic assembly machine through four upper pressing block fastening devices 3 . The upper pressing block fastening device 3 includes an upper T-shaped nut 31 located in the upper T-shaped groove 121, an upper pressing block 32 located on the bot...

Problems solved by technology

[0005] The connection structure between such a hydraulic assembly machine and the special fixture takes a long time to install, and it is necessary to install a positioning rod 211 on the upper template 21 of the special fixture to realize the positioning between the upper template 21 and the lower template 22, which virtually increases the special fixture. Processing cost and volume

[0006] At the same time, if the company produces many types of products, and different products need to be replaced with different special fixtures, so the special fixtures on the hydraulic assembly machine are replaced more frequently. The current connection structure between the hydraulic assembly machine and the special fixture will seriously affect the production efficiency.
