Technical Field

[0001] This utility model relates to the field of mechanical equipment, specifically to a clamping mechanism. Background Technology

[0002] Products typically require clamping during transport or processing. However, existing clamping cylinders can only clamp one product at a time. When multiple products need to be transported simultaneously, numerous clamping cylinders are required. Since these cylinders require air pipes for air supply to control the grippers, a large number of pipes are needed, resulting in a cluttered and costly clamping system.

[0003] Therefore, the technical problem that this application needs to solve is: how to reduce the number of clamping cylinders used when clamping multiple products. Utility Model Content

Detailed Implementation

[0027] The technical solutions of this application will be further described below with reference to specific embodiments, but this application is not limited to these embodiments.

[0028] like Figures 1 to 7 As shown, this embodiment proposes a clamping mechanism, including:

[0029] Drive assembly 11, the drive assembly 11 having two clamping arms 12;

[0030] The number of translation plates 13 is two, and there is a gap between the two translation plates 13. One translation plate 13 is installed on one of the clamping arms 12, and the other translation plate 13 is installed on the other clamping arm 12.

[0031] The clamping assembly has two clamping members 14 for clamping the product 20. One clamping member 14 is mounted on a translation plate 13, and the other clamping member 14 is mounted on another translation plate 13. The number of clamping assemblies is multiple.

[0032] The technical advantages of this solution are: it can clamp multiple products 20 at once, has a compact structure, and can significantly reduce the number of driving components used.

[0033] The number of clamping members 14 provided on the translation plate 13 is four or more. When the drive assembly 11 is working, the two clamping arms 12 move closer to each other, thereby driving the two translation plates 13 to move closer to each other, and the clamping members on the translation plates 13 move closer to each other, thereby clamping the product 20.

[0034] Furthermore, the drive assembly 11 adopts the existing clamping cylinder 29. It should also be noted that the clamping cylinder 29 itself, also called a pneumatic finger, pneumatic gripper, or pneumatic finger clamp, has two clamping arms 12 that can move closer or further apart. It is an existing standard component and a common device. Therefore, the structure and principle of the clamping cylinder 29 will not be described in detail here.

[0035] Alternatively, the drive assembly 11 can also employ multiple individual linear cylinders, with a clamping arm 12 fixed to the output end of each cylinder.

[0036] In one embodiment of this invention, the translation plate 13 is fixed to the clamping arm 12 via the connecting seat 15.

[0037] Furthermore, the connecting seat 15 includes a fixing block 16, a shim block 17, and a connecting block 18. The lower end of the connecting block 18 is fixed to the fixing block 16 via the shim block 17. The fixing block 16 is fixedly connected to the clamping arm 12. The translation plate 13 is fixed on the connecting block 18.

[0038] Furthermore, each clamping member 14 includes a first clamping part 30 and a second clamping part 31. The first clamping part 30 is fixed on the translation plate 13, and the first clamping part 30 is used to clamp the second clamping part 31, and the second clamping part 31 is used to clamp the product 20.

[0039] Furthermore, the second clamping part 31 is provided with a limiting notch 32, which is used to clamp the annular protrusion 33 on the circumference of the product 20.

[0040] In one embodiment of this invention, the number of driving components 11 is two, and the two driving components 11 are installed at both ends of the translation plate 13 in the length direction.

[0041] As one embodiment of this invention, it also includes an elastic abutment 19, which is used to abut the lower end of the product 20.

[0042] Furthermore, it also includes a base plate 21 and a mounting plate 22. The drive assembly 11 and the elastic clamping member 19 are fixed on the base plate 21. The mounting plate 22 is located above the base plate 21 and is fixed to the base plate 21 by a support plate 34. The mounting plate 22 is provided with a clearance opening 23 for accommodating the clamping member 14.

[0043] In one embodiment of this invention, the elastic clamping member 19 includes a sleeve 24, a clamping rod 25, and a spring 26. The bottom of the sleeve 24 is fixed on the base plate 21. The clamping rod 25 is slidably inserted into the inner hole of the sleeve 24 in the vertical direction. An annular block 27 is provided on the circumferential surface of the clamping rod 25. The spring 26 is sleeved on the outer circumference of the clamping rod 25. The upper end of the spring 26 abuts against the annular block 27, and the lower end of the spring 26 abuts against the upper end of the sleeve 24.

[0044] Furthermore, the mounting plate 22 has an mounting opening, in which a positioning block 28 is fixed. The positioning block 28 has a through hole for inserting a top clamping rod 25.

[0045] In this design, the clamping rod 25, under the action of the spring 26, can press the product 20 upward, thereby cooperating with the clamping member 14 in the vertical direction and preventing the product 20 from moving in the vertical direction.

[0046] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
