DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0028] like Figures 1 to 5 As shown, an automobile parts clamping tool of the present invention comprises a base 1 for carrying a part 2 and a plurality of clamping units 3 arranged on the base 1, wherein the clamping units 3 are used to press down and fix the part 2;

[0029] The clamping unit 3 includes a vertical sliding shaft 4 and a support plate 5, a movable platform 6 is fixed on the top of the sliding shaft 4, the movable platform 6 is horizontal, and the two ends of the movable platform 6 are respectively rotatably provided with a first adjustment arm 7 and a second adjustment arm 8, a guide arm 9 is rotatably provided on the support plate 5, and the end of the second adjustment arm 8 is rotatably provided in the middle of the guide arm 9, and a clamping plate 10 is arranged above the movable platform 6, the first adjustment arm 7 and the guide arm 9 are both rotatably connected to the clamping plate 10, and the end of the clamping plate 10 is used to probe into the hollow area of ​​the part 2 and press the part 2 down and fix it;

[0030] When the sliding shaft 4 moves, it pulls the guide arm 9 to tilt through the moving platform 6 and the second adjusting arm 8. The moving platform 6 simultaneously drives the first adjusting arm 7 to move. The first adjusting arm 7 and the guide arm 9 act together on the splint 10 and drive it to move in an arc.

[0031] In detail, when the part 2 is fixed, it is placed on the base 1, and the base 1 provides installation positions for multiple groups of clamping units 3. The multiple groups of clamping units 3 can be used to fix the base 1, and the number of clamping units 3 can be assembled according to actual needs. The support plate 5 is used to support the guide arm 9, and the sliding shaft 4 can move in the vertical direction. The rotation connection point between the guide arm 9 and the clamping plate 10 is located in the middle of the clamping plate 10. The clamping plate 10 on one side of the guide arm 9 is used to connect with the first adjusting arm 7, and the clamping plate 10 on the other side of the guide arm 9 is used to press the part 2. When the sliding shaft 4 moves downward, the guide arm 9 tilts in the direction away from the part 2, and the guide arm 9 guides and supports the clamping plate 10. At this time, the clamping plate 10 synchronously moves in the direction away from the part 2, and the clamping plate 10 moves downward in the vertical direction, so that the clamping plate 10 is away from the part 2.

[0032] When in use, place part 2 on base 1, with the hollow position on part 2 facing toward clamping unit 3, push sliding shaft 4 upward, sliding shaft 4 will push guide arm 9 from horizontal state to vertical state gradually through moving platform 6 and second adjusting arm 8, guide arm 9 synchronously drives splint 10 to move, so that splint 10 moves toward part 2, moving platform 6 synchronously provides pushing action for splint 10 through first adjusting arm 7, so that splint 10 gradually approaches part 2 under the guiding action of guide arm 9 and makes the end of splint 10 inserted into the hollow position of part 2, and splint 10 moves downward in vertical direction toward the end of part 2 under the pushing action of first adjusting arm 7, with the rotating connection point of guide arm 9 and splint 10 as the fulcrum of lever, so that splint 10 is used to produce downward pressing and fixing action on part 2 by splint 10.

[0033] It should be pointed out that, as the guide arm 9 rotates close to the vertical state, the speed at which the guide arm 9 pushes the splint 10 in the vertical direction gradually decreases, while the first adjusting arm 7 pushes the splint 10 in the vertical direction at a higher speed. Therefore, the end of the splint 10 toward the part 2 will move downward in the vertical direction, thereby causing the splint 10 to exert a downward pressure on the part 2. This structural method can realize a probe-type downward pressure fixing method. If a traditional structure wants to achieve this function, it needs to configure vertical power and lateral power, and its structure is complex and the operation is cumbersome.

[0034] Since the clamping plate 10 exerts a downward pressing and fixing effect on the component 2 when the sliding shaft 4 moves upward, the movement direction thereof is opposite.

[0035] By adopting a special probe-type downward pressing and fixing method, the splint 10 used to press the part 2 can be conveniently sent into the hollow position of the part 2 and the part 2 can be pressed down, so that the part 2 can be effectively and directly pressed down and fixed, avoiding the phenomenon that the part 2 is deformed and damaged due to the hollowing out of the part 2 when directly pressed down in the traditional method, and because the splint 10 needs to probe into the part 2 when the part 2 is fixed, the splint 10 can have a larger movable range in the horizontal direction, thereby providing a larger space for the disassembly and assembly of the part 2, and its flexibility is higher; since the clamping work only needs to rely on the linear motion of the sliding shaft 4 to complete, its structure is simple and easy to operate. At the same time, through clever design, the clamping tooling can realize the extension and contraction function in the inclined direction, and it occupies less space; in summary, this new type of automotive parts clamping tooling can effectively solve the problems existing in the traditional clamping method when fixing hollow-shaped parts, and through its unique working principle, it simplifies the operation process and improves processing accuracy and production efficiency.

[0036] Furthermore, a notch is formed at the end of the clamping plate 10 facing the part 2 , and a pressing block 11 is rotatably arranged in the notch. The pressing block 11 is connected to the clamping plate 10 via a first elastic sheet 12 .

[0037] In detail, when the end of the splint 10 is inserted into the hollow position of the part 2 and presses the part 2 downward, the splint 10 will push the pressure block 11 to contact the part 2. Since the pressure block 11 can rotate on the splint 10, the lower surface of the pressure block 11 can be in surface contact with the part 2. Even when the splint 10 is tilted, it can still be in surface contact with the part 2 through the pressure block 11, thereby providing effective downward pressure for the part 2. The first spring sheet 12 can provide a reset elastic force for the pressure block 11.

[0038] Furthermore, a baffle 13 is rolled on the side wall of the support plate 5 , and the baffle 13 is used to limit the rotation angle of the guide arm 9 . The guide arm 9 and the baffle 13 are connected via a second elastic sheet 14 .

[0039] In detail, when the guide arm 9 rotates to a vertical state, the side wall of the guide arm 9 contacts the side wall of the baffle 13. At this time, the baffle 13 has a limiting effect on the guide arm 9, preventing the guide arm 9 from rotating beyond its specified formation and driving the clamping plate 10 to move downward. The second spring piece 14 can provide an elastic force for the guide arm 9, so that the various structures in the clamping unit 3 maintain a close connection relationship and avoid the occurrence of loosening due to gaps.

[0040] Furthermore, a slider 15 is slidably provided on the guide arm 9 along the length direction of the guide arm 9 , the second adjustment arm 8 is rotatably connected to the slider 15 , and a limiting protrusion 16 for limiting the sliding position of the slider 15 is provided on the guide arm 9 .

[0041] In detail, the limiting protrusion 16 limits the moving position of the slider 15 toward the support plate 5. In the natural state, due to the action of the second spring piece 14, the slider 15 contacts the limiting protrusion 16. When the sliding shaft 4 moves upward, the slider 15 and the limiting protrusion 16 remain in contact. When the guide arm 9 contacts the baffle 13, the guide arm 9 no longer moves. At this time, the sliding shaft 4 can continue to move and drive the slider 15 to slide on the guide arm 9. The slider 15 is separated from the limiting protrusion 16, and the moving platform 6 can continue to provide thrust to the splint 10 through the first adjusting arm 7, so that the splint 10 continues to move downward toward the end of the part 2. This structural method can increase the active range of the working end of the splint 10, thereby increasing its clamping range.

[0042] Furthermore, the clamping unit 3 also includes a turntable 17 rotatably mounted on the base 1 , the slide shaft 4 passes through the turntable 17 and slides relatively, the support plate 5 is arranged on the turntable 17 , and a cylinder 18 for providing power to the slide shaft 4 is arranged on the turntable 17 .

[0043] In detail, when it is necessary to clamp parts of different placement positions and shapes, the clamping unit 3 can be adjusted to a suitable position by rotating the turntable 17, thereby increasing the range of motion and the clamping interval, and the cylinder 18 provides power for the movement of the sliding shaft 4.

[0044] Furthermore, the support plate 5 passes through the turntable 17 and slides relatively thereto, and a locking structure is provided between the turntable 17 and the support plate 5 .

[0045] In detail, when it is necessary to adjust the clamping interval of the clamping unit 3 in the vertical direction, the height position of the support plate 5 on the turntable 17 can be adjusted, so as to facilitate clamping of parts with different thicknesses or heights.

[0046] Further, the bottom of the support plate 5 is horizontal, and the cylinder 18 is fixed on the support plate 5;

[0047] The locking structure includes a threaded rod 19 rotatably mounted at the bottom of the turntable 17. The threaded rod 19 passes through the support plate 5 and is threadedly connected to each other. A plurality of slots are provided on the threaded rod 19. The length direction of the slots is along the axis direction of the threaded rod 19. A card plate 20 is slidably provided at the bottom of the support plate 5. The card plate 20 is used in conjunction with the slots. The card plate 20 and the support plate 5 are connected by a third spring piece 21.

[0048] In detail, when the card plate 20 is inserted into the card slot, the threaded rod 19 cannot rotate. When the card plate 20 is moved out of the card slot, the threaded rod 19 can rotate freely. Since the threaded rod 19 is threadedly connected to the support plate 5, the threaded rod 19 can push the support plate 5 to move up and down, thereby adjusting the clamping range of the clamping unit 3 in the vertical direction. When the support plate 5 moves, it will drive the cylinder 18 to move synchronously. When the position adjustment of the clamping unit 3 is completed, the card plate 20 is released, and the third spring piece 21 will push the card plate 20 to be clamped into the corresponding card slot.

[0049] Furthermore, a worm gear groove 22 is provided on the circumferential outer wall of the rotating disk 17 , a worm gear 24 is meshedly provided on the worm gear groove 22 , a motor 23 is provided on the worm gear 24 , the motor 23 provides power for the worm gear 24 , and the motor 23 is fixed on the base 1 .

[0050] In detail, the motor 23 can provide power for the rotation of the turntable 17 through the worm 24 and the worm gear groove 22 .

[0051] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
