Detailed Description

The following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings to make it clear to those skilled in the art how to practice the invention. While the invention has been described in connection with its preferred embodiments, these embodiments are intended to be illustrative, and not to limit the scope of the invention.

Referring to fig. 1 to 4, the mechanical arm clamp connecting device comprises a male head 1, a female head 2 and a locking device.

Public first 1 is used for being connected with different contained angles through the bolt, and the contained angle can be tongs, sucking disc or other snatchs mechanisms, female first 2 is used for being connected with the arm through the bolt, and public first 1 and female first 2 are connected through respective sliding structure, and in this embodiment, the slider structure on public first 1 is bellied slider 101, and the sliding structure on female first 2 is the spout 201 of indent, and public first 1 is connected through slider 101 and spout 201 cooperation with female first 2.

The locking device comprises two fixing pin assemblies, a lifting shaft 6, a pry bar 7, an extension pry bar 8, a pin bolt 9, a pin nut 10 and a butterfly bolt 11.

Two first pin holes 102 are formed in one side of the sliding block 101 of the male head 1, two second pin holes 202 corresponding to the two first pin holes 102 are formed in one side of the sliding groove 201 of the female head 2, and the two fixing pin assemblies are respectively installed in the two second pin holes 202 of the female head 2. Referring to fig. 4 and 5, each fixing pin assembly includes a gland 3, a fixing pin 4, and a spring 5, the gland 3 is fixedly connected in the second pin hole 202, the fixing pin 4 is inserted into the second pin hole 202, one end of the fixing pin 4 is inserted out of the gland 3, a shoulder is provided at the other end of the fixing pin 4, the spring 5 is sleeved on the fixing pin 4, and both ends of the spring are respectively abutted against the shoulders of the gland 3 and the fixing pin 4 to be in a compressed state, and the other end of the fixing pin 4 is inserted into the corresponding first pin hole 102 under the action of the spring 5.
