[0025] In order to make the purpose, technical scheme and advantages of the present invention more clear, the present invention will now be further described in detail with reference to the accompanying drawings and the following examples so that the public can better understand the implementation method of the present invention. The specific implementation scheme of the present invention is as follows:

[0026] A boom box clamping device comprises a connecting arm 1 which is arranged in a cylindrical structure, a left clamping claw 2 is symmetrically arranged on the left side of the connecting arm 1 by means of a sliding structure, each left clamping claw 2 is arranged with a connecting rod 3 by means of a hinged structure, a telescopic arm 4 is arranged on the other end of the connecting rod 3 by means of a hinged structure, the telescopic arm 4 is arranged in the connecting arm 1 by means of a sliding structure, a power member 5 for driving the telescopic arm 4 to move is also arranged in the connecting arm 1, one end of the power member 5 is hingedly connected to the connecting arm 1, and the other end is connected to the telescopic arm 4; the telescopic arm 4 is provided with a moving claw 6 in a fixed structure, the connecting arm 1 is provided with a fixed claw 7 in a fixed structure, the left clamping claw 2 is arranged on the left side of the connecting arm 1, and the fixed claw 7 and the moving claw 6 are arranged at the lower part, through the above structural design and layout, the simultaneous clamping of two boom boxes can be realized on one manipulator, which saves the investment in the manipulator and reduces the occupancy of the factory building, thus killing two birds with one stone.

[0027] It should be noted that the power member 5 can be a linear power member such as a cylinder or an oil cylinder, or can be a mechanism that converts rotational motion into linear motion.

[0028] It is also convenient to use the two left clamps 2 to grab the welded boom box and then place it horizontally in the shelf.

[0029] It should be noted that a mounting plate 8 is provided on one side of the connecting arm 1 by means of a fixed structure, and slide rails 9 are provided on the upper and lower sides of the outside of the mounting plate 8 by means of a fixed structure, and a slider 10 is provided on the slide rail 9 by means of a sliding structure, and the slider 10 is connected to the connecting rod 3 by means of a hinge structure, and the slider 10 is fixedly connected to the left clamp 2 in a one-to-one correspondence, and the power part 5 drives the connecting rod 3 through the telescopic arm 4, and the connecting rod 3 drives the slider 10 to move on the slide rail 9, thereby realizing the closing and opening of the left clamp.

[0030] In order to meet the requirement of relatively large opening and closing of the left clamping jaw 2, the connecting rod 3 is designed to be an arc-shaped structure.

[0031] Specifically, the connecting arm 1 is provided with a through hole for the mobile claw 6 to move axially, and the mobile claw 6 and the fixed claw 7 both include a sleeve 11, and the upper end surface of the sleeve 11 is provided with a telescopic cylinder A12 in a fixed structure, and the output shaft of the telescopic cylinder A12 extends into the sleeve 11 and is connected with a pull rod 13, and the lower end of the connecting rod 3 is provided with a pressure claw 14 in a hinged structure, and an inclined groove 15 is provided on the pressure claw 14, and a fixed shaft is provided in the inclined groove 15, and the fixed shaft is connected to the sleeve 11 in a fixed structure. The lower part of the sleeve 11 is extended into the pin hole of the boom box pin shaft through the movement of the manipulator, and then the telescopic cylinder A12 is used to drive the pressure claw 14 to hook the lower end surface of the pin shaft through the pull rod 13, so that the boom box can be clamped. In order to facilitate the upper limit of the pin shaft, a limit plate 16 is sleeved on the outside of the sleeve 11.

[0032] A power part 5 can be used to drive the moving claw 6 to clamp a boom box in cooperation with the pressure claw 14. By moving again, the left clamp 2 can be used to clamp another boom box. Through the design of the structure of this solution, the clamping of two workpieces, a left station and a lower station, is achieved by a power part, leaving enough space to avoid affecting the welding path of the welding robot.

[0033] In order to ensure stability during the clamping and welding process, a locking structure for locking the telescopic arm 4 is also provided. The locking structure includes a locking hole 17 and a locking tongue adapted to the locking hole 17. The locking tongue is provided with a telescopic cylinder B18 in a fixed structure manner. The telescopic cylinder B18 is connected to the connecting arm 1 in a fixed structure manner. One locking structure can be used to lock two workstations at the same time, thereby improving structural stability and avoiding safety accidents caused by the falling off of the boom box due to failure of the power parts.

[0034] The working principle and working process of the present invention are as follows:

[0035] The device is installed at the front end of the manipulator. The fixed claw 7 and the movable claw 6 are extended into the pin shaft of the boom box A through the action of the manipulator. Then the telescopic cylinder A12 is started. The telescopic cylinder A12 pulls the pressure claw 14 upward through the pull rod 13. Due to the cooperation between the inclined groove 15 and the fixed shaft, the lower part of the pressure claw 14 moves inward to hook the lower end surface of the pin shaft. At this time, there is no need to continue clamping. The boom box A can move left and right. Then the left clamping claw 2 is used to clamp the boom box B. The cylinder 5 pulls the connecting rod 3 to the right. The connecting rod 3 pulls the slider 10 to move inward along the slide rail 9, thereby driving the left clamping claw 2 to clamp the boom box B.

[0036] Then start the telescopic cylinder B18 to drive the lock tongue to extend into the lock hole 17 to lock the telescopic arm 4 to ensure the stability of the boom box during full welding.
