[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1 to 5 The utility model provides a technical solution: a mechanical parts clamping and fixing device, including a workbench 1, a support plate 2 is installed in the workbench 1, two sliding frames 4 are fixed on the workbench 1, a slider 5 is slidably matched in the sliding frame 4, a positioning structure is installed on one side of the slider 5, a clamping frame 14 is rotatably matched between the two sliders 5, a plurality of pneumatic rods 10 are installed in the clamping frame 14, a chuck 11 is installed at one end of the pneumatic rod 10, a clamping structure is installed between the chuck 11 and the pneumatic rod 10, and mechanical parts are installed between the plurality of chucks 11.

[0023] In this embodiment, a through slot 15 is provided in the workbench 1 , and the through slot 15 corresponds to the support plate 2 . An electric cylinder 3 is fixed to the lower side of the workbench 1 , and an output end of the electric cylinder 3 is fixedly connected to the support plate 2 .

[0024] Specifically, when clamping the mechanical part, the support plate 2 and the workbench 1 are on the same plane, and at this time, the bottom of the mechanical part is in contact with the support plate 2, so that the mechanical part can be supported.

[0025] When the mechanical part needs to be turned over, the electric cylinder 3 can be started to drive the support plate 2 to move downward, so that the support plate 2 no longer limits the clamping frame 14, and the clamping frame 14 can be driven to rotate, thereby driving the mechanical part to be turned over.

[0026] A slide groove 6 is provided in the sliding frame 4, and the slide groove 6 corresponds to the slider 5. A rotating shaft 7 is installed between the slider 5 and the clamping frame 14. The positioning structure includes a screw rod 8 and a nut 9. The rotating shaft 7 is rotatably connected to the slider 5. The screw rod 8 corresponds to the nut 9, and the screw 8 corresponds to the rotating shaft 7.

[0027] Specifically, when the mechanical parts are relatively high, the slide block 5 can be slid upward, so that the slide block 5 drives the clamping frame 14 to slide upward, thereby facilitating the clamping of the mechanical parts.

[0028] The rotating shaft 7 is fixedly connected to the clamping frame 14 , the screw rod 8 passes through the slider 5 and is fixedly connected to the rotating shaft 7 , and the screw rod 8 is rotatably connected to the slider 5 .

[0029] When the position of the clamping frame 14 needs to be fixed, the nut 9 can be rotated to make the nut 9 contact the sliding frame 4, so that the nut 9 squeezes the sliding frame 4, the position of the slider 5 can be fixed, and the larger friction can prevent the clamping frame 14 from rotating.

[0030] The pneumatic rod 10 is fixed to the peripheral side of the clamping frame 14, and the clamping structure includes a clamping block 12 and a clamping slot 13. The output end of the pneumatic rod 10 is fixedly connected to the clamping block 12. The clamping slot 13 is opened in the chuck 11. The clamping block 12 corresponds to the clamping slot 13, and the clamping block 12 is made of elastic material.

[0031] Specifically, the pneumatic rod 10 can be used to drive the chuck 11 to clamp and fix the mechanical parts. When the chuck 11 needs to be replaced, the chuck 11 can be pulled to separate the clamping block 12 from the clamping slot 13, so that the chuck 11 can be removed and replaced so that the chuck 11 is adapted to the mechanical parts.

[0032] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
