[0002] Bolts are an extremely important part, used to connect and fix multiple parts. They have a wide range of applications and are also an indispensable and important part in automobiles, used to connect various parts on the car. During the bolt processing, the burrs on the surface need to be removed, and a clamping device must be used during the processing to fix the bolts.

[0003] For example, the Chinese patent publication number CN215942386U discloses a high-strength protective clamping device for automobile bolt production, including a workbench, the top surface of the workbench vertically fixes a support column, the bottom panel of the support column passes through a mounting groove, the upper end of the support column is movably sleeved with a first locking sleeve, the top surface of the first locking sleeve passes through a threaded hole, two semi-cylindrical counterweights are installed in the mounting groove, the first locking sleeve is threadedly connected to the upper end of the counterweight, the top surface of the counterweight vertically fixes the support block, the top surface of the support block vertically fixes the sleeve, the inner wall of the first locking sleeve is provided with a first internal thread, and the first locking sleeve is threadedly connected to the upper half of the support column. This scheme further improves the stability of the bolt clamping during the processing process, avoids the bolt from detaching from the clamping device when the bolt is clamped, thereby affecting the accuracy of the bolt processing size, thereby solving the problem of the clamping device not clamping the bolt tightly enough during the processing of the bolt.

[0004] Although the above example can fix the automobile bolt during the processing, when both ends of the bolt need to be processed, after completing the processing of one end of the automobile bolt, the automobile bolt needs to be removed and clamped again. The operation steps are relatively cumbersome, which affects the processing efficiency of the bolt. At the same time, when processing the automobile bolt, only one automobile bolt can be fixed at a time, and multiple automobile bolts cannot be fixed, resulting in low processing efficiency of the automobile bolt and certain inconveniences in use.

[0025] In this embodiment, when the automobile bolt 310 is flipped, the fixing rod 24 is pulled out from the support frame 21, and the motor 22 is started. Under the action of the motor 22, the placement plate 23 is rotated to flip the automobile bolt 310. After the other end of the automobile bolt 310 is flipped upward, the fixing rod 24 is inserted into the support frame 21 again to fix the placement plate 23, thereby preventing the placement plate 23 from rotating when the automobile bolt 310 is processed, making it more convenient to use.

[0026] Example 2

[0027] like Figure 1-4 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the clamping mechanism 3 includes a motor 2 31, the surface of the motor 2 31 is fixedly connected to the surface of the placement plate 23, one end of the rotating shaft of the motor 2 31 is fixedly connected to a gear 32, the surface of the gear 32 is meshed with a rack 34, a mounting groove 33 is provided inside the placement plate 23, a sliding block 35 is fixedly connected to the side of the rack 34 away from the gear 32, a sliding groove 1 36 is provided on the inner wall of the mounting groove 33, the inner wall of the sliding groove 1 36 is slidably connected to the surface of the sliding block 35, one end of the rack 34 is fixedly connected to a clamping plate 37, the side of the clamping plate 37 close to the rack 34 is fixedly connected to a clamping block 38, the surface of the clamping block 38 is fixedly connected to a rubber pad 39, and the side of the rubber pad 39 away from the clamping block 38 is overlapped with an automobile bolt 310.

[0028] In this embodiment, by starting the motor 2 31, under the action of the motor 2 31, the gear 32 rotates to drive the rack 34 to move, and then the rack 34 drives the clamping block 38 to clamp and fix the automobile bolt. At the same time, during the movement of the clamping block 38, the rack 34 drives the sliding block 35 to slide along the sliding groove 1 36 to limit the rack 34 to prevent the rack 34 from shaking, so that the clamping effect is better. At the same time, the setting of the rubber pad 39 increases the friction between the clamping block 38 and the automobile bolt 310, so that the clamping effect is further improved.

[0029] Example 3

[0030] like Figure 1-4As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the limiting mechanism 4 includes a motor three 41, the surface of the motor three 41 is fixedly connected to the bottom of the base 1, one end of the rotating shaft of the motor three 41 is fixedly connected to a threaded rod 42, a sliding groove two 43 is provided inside the support frame 21, the inner wall of the sliding groove two 43 is rotatably connected to one end of the threaded rod 42, the surface of the threaded rod 42 is threadedly connected to a limiting plate 44, the inner part of the limiting plate 44 is slidably connected to a guide rod 45, the two ends of the guide rod 45 are fixedly connected to the inner wall of the sliding groove two 43, the top of the limiting plate 44 is provided with a hexagonal groove 46, and the bottom of the inner cavity of the hexagonal groove 46 overlaps with one end of the automobile bolt 310.

[0031] In this embodiment, when processing the automobile bolt 310, the automobile bolt 310 is first inserted into the through hole on the surface of the placement plate 23. Under the action of the limiting plate 44, the fixed positions of multiple automobile bolts 310 can be kept consistent, making it easier to process. After the processing is completed, the motor 41 is started to rotate the threaded rod 42 to drive the limiting plate 44 to slide downward along the guide rod 45, so that the hexagonal groove 46 is disengaged from one end of the automobile bolt 310, and the automobile bolt 310 can be flipped.

[0032] The working principle of the clamping device for automobile bolt production will be described in detail below.

[0033] like Figure 1-4 As shown, when processing the automobile bolt 310, first insert the automobile bolt 310 into the through hole on the surface of the placement plate 23. Under the action of the limiting plate 44, the fixing positions of multiple automobile bolts 310 can be kept consistent. Then, the motor 2 31 is started. Under the action of the motor 2 31, the gear 32 rotates to drive the rack 34 to move, so that the rack 34 drives the clamping block 38 to clamp and fix the automobile bolt. At the same time, during the movement of the clamping block 38, the rack 34 drives the sliding block 35 to slide along the sliding groove 1 36 to limit the rack 34 to prevent the rack 34 from shaking, so that the clamping effect is better. At the same time, the setting of the rubber pad 39 increases the friction between the clamping block 38 and the automobile bolt 310. The friction force further improves the clamping effect. After the clamping is completed, one end of the automobile bolt 310 is processed. After the processing is completed, the motor three 41 is started to rotate the threaded rod 42 to drive the limit plate 44 to slide downward along the guide rod 45, so that the hexagonal groove 46 is disengaged from one end of the automobile bolt 310, and the fixing rod 24 is pulled out from the support frame 21, and the motor one 22 is started. Under the action of the motor one 22, the placement plate 23 is rotated to flip the automobile bolt 310. After the other end of the automobile bolt 310 is flipped upward, the fixing rod 24 is inserted into the support frame 21 again to fix the placement plate 23 to prevent the placement plate 23 from rotating when the automobile bolt 310 is processed, making it more convenient to use.

[0034] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
