Technical Field

[0001] The utility model relates to the field of clamping tools, and more specifically, to an automatic clamping device. Background Art

[0002] Before processing the parts of a product, it is necessary to clamp and fix the parts to meet the requirements of part processing. During the process of manufacturing the parts of a product, it is necessary to repeatedly process different sides of the parts. Therefore, it is necessary to often rotate the parts during processing. In the prior art, it is usually manually flipped. However, the work of manually flipping parts is a cumbersome mechanical repetitive action. Workers are very prone to fatigue when repeating an action for a long time, resulting in low labor efficiency, extremely high danger, poor consistency, and there is no matching flipping mechanism in the existing clamping device, making it impossible to give full play to the automatic flipping function of the manipulator for the product. Therefore, it is necessary to redesign an automatic clamping device for the above problems. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Referring to Figures 1-5 , an automatic clamping device includes a mounting base 1. A driving device is fixedly installed on the upper end surface of the mounting base 1. Two mounting blocks 3 are symmetrically and fixedly installed on the upper end surface of the mounting base 1. A rotating device is rotatably connected between the two mounting blocks 3, and the output end of the rotating device is connected to the output end of the driving device. A chute 11 is provided on the output end of the rotating device, and a clamping device is provided in the chute 11.

[0026] As shown in Figures 1-5As shown, the implementation method is specifically as follows: By setting a clamping device and a motor 5, the motor 5 can drive the double-headed threaded rod 12 to drive the slider 15 and the clamping plate 14 to automatically clamp and release the article. By setting a driving device and a rotating device, the output shaft of the cylinder 2 can drive the fixed plate 6 to move synchronously. Subsequently, the fixed plate 6 can drive the rack 7 to move synchronously. Since the rack 7 meshes with the gear 17, when the rack 7 moves, the gear 17 will drive the gear 17 to rotate. Subsequently, the rotation of the gear 17 can drive the fixed shaft 8 to rotate synchronously. Then, the rotation of the fixed shaft 8 can drive the two fixed blocks 13 fixed on its outer wall to rotate synchronously. Subsequently, the two fixed blocks 13 can drive the mounting plate 4 and the clamping device to flip, and at this time, the clamped article can be flipped.

[0027] The driving device includes a cylinder 2, and the cylinder 2 is fixedly installed on the upper end surface of the mounting base 1. A fixed plate 6 is fixedly connected to the output shaft of the cylinder 2. A rack 7 is fixedly installed on the upper end surface of the fixed plate 6, and the rack 7 is connected to the output end of the rotating device.

[0028] The rotating device includes a fixed shaft 8, and the fixed shaft 8 is rotatably connected between the two mounting blocks 3. A gear 17 is fixedly installed on the outer wall of the fixed shaft 8, and the gear 17 meshes with the rack 7. Two fixed blocks 13 are symmetrically and fixedly installed on the outer wall of the fixed shaft 8. The upper end surfaces of the two fixed blocks 13 are fixedly connected to a mounting plate 4 together, and a chute 11 is opened on the upper end surface of the mounting plate 4. The movement of the rack 7 can drive the gear 17 to rotate. Since the gear 17 is fixedly connected to the fixed shaft 8, when the gear 17 rotates, the fixed shaft 8 will rotate synchronously.

[0029] The clamping device includes a double-headed threaded rod 12, and one end of the double-headed threaded rod 12 is installed on the inner side wall of the chute 11 through a bearing. The double-headed threaded rod 12 is threadedly connected to two sliders 15. The upper end surface of each slider 15 is fixedly installed with a clamping plate 14. It should be noted that: the two sliders 15 are respectively threadedly connected to the two opposite threads of the double-headed threaded rod 12.

[0030] A plurality of anti-slip grooves 16 are opened on one side of each clamping plate 14, and the anti-slip grooves 16 can increase the friction force between the clamped article and the clamping plate 14.

[0031] Two fixing rods 10 are symmetrically and fixedly installed at one end of the mounting plate 4. The two fixing rods 10 are fixedly installed together at the end far from the mounting plate 4 with a motor 5, and the output shaft of the motor 5 penetrates through one side of the mounting plate 4 and is fixedly connected to one end of the double-headed threaded rod 12. Furthermore, the rotation of the output shaft of the motor 5 can be used to drive the double-headed threaded rod 12 to rotate.

[0032] On one side of each mounting block 3, a limiting block 9 is fixedly installed. Each limiting block 9 is made of rubber material. It should be noted that such a design can prevent the limiting block 9 from damaging the mounting plate 4 when the limiting block 9 contacts the mounting plate 4.

[0033] When the utility model is in use, first, the motor 5 can be started. The output shaft of the motor 5 can drive the double-headed threaded rod 12 to rotate. Subsequently, the two sliders 15 threadedly connected to the double-headed threaded rod 12 will slide relatively in the chute 11. The two sliders 15 will approach each other. Subsequently, the slider 15 will drive the clamping plate 14 fixedly connected thereto to clamp the article. The anti-slip groove 16 can be used to increase the friction between the clamped article and the clamping plate 14.

[0034] Subsequently, the cylinder 2 can be started. The output shaft of the cylinder 2 can drive the fixed plate 6 to move synchronously. Subsequently, the fixed plate 6 can drive the rack 7 to move synchronously. Since the rack 7 meshes with the gear 17, when the rack 7 moves, the gear 17 will drive the gear 17 to rotate. Subsequently, the rotation of the gear 17 can drive the fixed shaft 8 to rotate synchronously. Subsequently, the rotation of the fixed shaft 8 can drive the two fixed blocks 13 fixed on its outer wall to rotate synchronously. Subsequently, the two fixed blocks 13 can drive the mounting plate 4 to flip. At this time, the clamped article can be flipped. Subsequently, the motor 5 is reversed. The motor 5 can drive the double-headed threaded rod 12 to rotate synchronously. Subsequently, the two sliders 15 will drive the clamping plates 14 to move away from each other, and the clamped article can be released.

[0035] The two limiting blocks 9 can be used to limit the mounting plate 4 to prevent the mounting plate 4 from undergoing excessive displacement.

[0036] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
