Detailed implementation manners

[0029] In order to enable those skilled in the art to better understand the present utility model, the technical solutions of the present utility model will be further described below in conjunction with the drawings and embodiments.

[0030] As Figures 1-7 shown, a part clamping device of the present utility model includes a controller 1, and also includes

[0031] a bottom plate 11, and vertical plates 12 are symmetrically installed on the upper side of the bottom plate 11 on the left and right;

[0032] Two first mounting tables 2 are provided, and the two first mounting tables 2 are respectively fixedly installed on the upper parts of the two vertical plates 12 close to each other. Circular grooves 21 are formed on the sides of the two first mounting tables 2 close to each other, and a sliding rod 22 is fixedly installed on the sides of the two vertical plates 12 close to each other;

[0033] The lead screw 3 has one end fixedly connected to the right vertical plate 12, and the other end of the lead screw 3 extends out of the left vertical plate 12 with a turntable 31 fixedly installed on the end face. The lead screw 3 and the slide rod 22 are both located inside the two circular grooves 21;

[0034] The second mounting table 32 is slidably assembled around the slide rod 22, and the second mounting table 32 is threadedly connected to the lead screw 3;

[0035] There are three rotary clamping mechanisms 4, and the three rotary clamping mechanisms 4 are respectively fixedly installed on the upper sides of the two first mounting tables 2 and the second mounting table 32; Specifically, the rotary clamping mechanism 4 includes two mounting plates 41, and the two mounting plates 41 are respectively fixedly installed on the front and rear sides of the upper ends of the second mounting table 32 or the first mounting table 2. On the mutually remote sides of the two mounting plates 41, a brake motor 42 and a cylinder 43 are respectively fixedly installed. The output shaft of the brake motor 42 passes through the mounting plate 41 and is fixedly installed with a first clamping plate 44. The telescopic end of the cylinder 43 passes through the mounting plate 41 and is fixedly installed with a round block 45. A circular groove 46 is opened on the side of the round block 45 close to the first clamping plate 44. A connecting block 47 is rotatably assembled inside the circular groove 46. One end of the connecting block 47 close to the first clamping plate 44 is fixedly installed with a second clamping plate 48. A locking assembly is provided between the connecting block 47 and the round block 45. The brake motor 42 and the cylinder 43 are both electrically connected to the controller 1.

[0036] In the initial state, the locking assembly locks the connecting block 47, and then the connecting block 47 cannot rotate, and the second clamping plate 48 cannot rotate either. When it is necessary to clamp the automotive pedal element, hold the automotive pedal element and place it between the first clamping plate 44 and the second clamping plate 44. Then, start the cylinder 43 through the controller 1. The telescopic end of the cylinder 43 drives the second clamping plate 48 to approach the first clamping plate 44 until it contacts the part and clamps it, and then the cylinder 43 can be stopped. Three automotive pedal elements can be clamped in sequence according to the processing requirements. When it is necessary to spray paint the clamped part, after one side of the painting is completed, release the connection of the locking assembly to the connecting block 47, and control the output shaft of the brake motor 42 to rotate through the controller 1. Since the first clamping plate 44 and the second clamping plate 48 jointly clamp the part, when the first clamping plate 44 rotates, the clamping force can drive the second clamping plate 48 to rotate by using the clamping force, and then the rotation of the part is realized, which is convenient for painting different surfaces. After use, just use the locking assembly to lock it again.

[0037] The locking assembly includes a threaded rod 49. A plurality of connection holes 491 are circumferentially formed around the connecting block 47. A threaded through hole is formed in the circumference of the round block 45. The threaded rod 49 is threadedly connected inside the threaded through hole. The lower end of the threaded rod 49 extends into one of the connection holes 491, and a screwing block 492 is fixedly installed at the upper end of the threaded rod 49.

[0038] In the initial state, the threaded rod 49 is connected to one of the connection holes 491, and then the connecting block 47 cannot rotate. In this state, the clamping of the parts is more stable. When painting is required, when controlling the rotation of the parts, the turning block 492 can be rotated, and the turning block 492 drives the threaded rod 49 to withdraw from the connection with the connection hole 491. After unlocking, the connecting block 47 can rotate, and when locking again later, the connection is made again.

[0039] On the mutually remote sides of the two mounting plates 41, protective boxes 493 matching the brake motor 42 and the air cylinder 43 are respectively fixedly installed; the two protective boxes 493 can provide protection for the brake motor 42 and the air cylinder 43.

[0040] The controller 1 is installed on the front side of the left vertical plate 12, and the three rotary clamping mechanisms 4 are all electrically connected to the controller 1.

[0041] On the mutually close sides of the two vertical plates 12, expansion bellows 121 are respectively fixedly installed. The two expansion bellows 121 are respectively located inside the two circular grooves 21. The mutually close ends of the two expansion bellows 121 are respectively fixedly connected to the left and right sides of the second mounting table 32; when the second mounting table 32 moves left and right, the two expansion bellows 121 will expand and contract accordingly. The two expansion bellows 121 can protect the lead screw 3 and the slide rod 22, and prevent paint from falling onto the lead screw 3 and the slide rod 22 and solidifying during painting, which may affect the normal transmission of the lead screw 3 subsequently.

[0042] On the front side of the left vertical plate 12, an assembly plate 122 is fixedly installed. In front of the assembly plate 122, there is a protective shell 123. The controller 1 is fixedly installed on the front side of the assembly plate 122 and is located inside the protective shell 123; the protective shell 123 can be opened and closed, and the protective shell 123 can provide protection for the controller 1.

[0043] The usage method of this device is as follows:

[0044] In the initial state, the parts to be clamped are clamped. When clamping, the parts are placed between the first clamping plate 44 and the second clamping plate 48. Then, the air cylinder 43 is started through the controller 1. The telescopic end of the air cylinder 43 drives the second clamping plate 48 to approach the first clamping plate 44 to clamp the parts. After the parts are clamped, the staff controls the second mounting table 32 to approach the first mounting table 2 on the left or right according to the welding requirements, so that the two parts are abutted for welding. When adjusting, the turntable 31 is rotated, the turntable 31 drives the lead screw 3 to rotate, and the second mounting table 32 is driven to move left and right through the threaded connection between the second mounting table 32 and the lead screw 3. After welding is completed, the clamping can be released, or other parts can be directly welded onto the clamped parts. Three parts can be clamped at the same time, and welding work can be carried out in sequence with high work efficiency;

[0045] When spraying paint on the parts, the connection between the threaded rod 49 and the connection hole 491 can be released preferentially. Then, spray paint on the parts. When finishing spraying one side and starting to spray the other side, start the brake motor 42 through the controller 1. The brake motor 42 drives the first clamping plate 44 to rotate. Since the first clamping plate 44 and the second clamping plate 48 jointly clamp the parts, the clamping force can drive the second clamping plate 48 to rotate synchronously, and then turn over the parts. After the turning is completed, just turn off the brake motor 42. In this way, the turning operation of three parts can be completed at the same time without re-clamping, and the operation is convenient and the work efficiency is high.

[0046] The above embodiments only exemplarily illustrate the principle and its effects of the present invention, rather than limiting the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
