[0018] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0019] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0020] In one embodiment of the present invention, Figure 1 , 2As shown, an efficient clamping device is provided for clamping a sandblasting jig 1. Specifically, the sandblasting jig 1 includes a rectangular frame 11 arranged on the periphery and a plurality of fixing members 12 arranged in the frame 11 at intervals therefrom. The fixing members 12 include a plurality of card slots 121 for fixing products. The card slots 121 include a first card member and a second card member. It should be noted that: the first card member and the second card member are elastically designed, and the notch of the card slot 121 can be controlled by applying an external force to the first card member and the second card member, which is suitable for assembling products of different specifications. Before and after the sandblasting process, the product needs to be loaded and unloaded. Specifically, before the sandblasting process, a force needs to be applied to the card slot by hand. The first clamp and the second clamp of 121 are pressed inwardly, and the product is assembled to the first clamp and the second clamp of the card slot 121. After releasing the hand, the first clamp and the second clamp of the card slot 121 fix the product to the first clamp and the second clamp under the action of the restoring force. After the sandblasting is completed, it is necessary to apply force to the first clamp and the second clamp of the card slot 121 by hand, and then take out the product. If the number of products is large, a lot of time will be wasted in the process of product loading and unloading, the operation efficiency is low, and it is time-consuming and labor-intensive. Therefore, it is necessary to design a sandblasting clamping device suitable for large quantities of small parts, which can quickly and efficiently complete the assembly of products.

[0021] Specifically, the clamping device includes a base plate 2 and a clamping mechanism 3 . A notch 21 is provided in the middle of the base plate 2 . The notch 21 is rectangular and is arranged corresponding to the sandblasting fixture 1 for arranging the clamping mechanism 3 . The clamping mechanism 3 includes a plurality of clamping components 31 and a driving assembly 32 for driving the clamping components 31 to clamp. Specifically, the clamping components 31 are arranged at intervals at the slot 21 in a transverse direction, and include a first push block 311 and a second push block 312 arranged opposite to each other. When in use, the fixing member 12 of the sandblasting jig 1 is clamped between the first push block 311 and the second push block 312, so that the slot 121 of the fixing member 12 is located between the first push block 311 and the second push block 312. At this time, the driving assembly 32 drives the first push block 311 and the second push block 312 to shift horizontally toward each other, so that the first clamp and the second clamp of the slot 121 can be squeezed inward. When the first clamp and the second clamp of the slot 121 are squeezed to a suitable position, the product can be quickly assembled onto the first clamp and the second clamp of the slot 121.

[0022] Further, the driving assembly 32 is vertically spaced at the bottom of the bottom plate 2, and is used to fix the clamping component 31 and drive the first push block 311 and the second push block 312 to shift vertically, so that the first push block 311 and the second push block 312 shift horizontally toward each other. Specifically, the driving assembly 32 includes a connecting shaft 321 vertically movably arranged below the slot 21, and the connecting shaft 321 includes a first connecting shaft 3211, a second connecting shaft 3212, a third connecting shaft 3213 and a fourth connecting shaft 3214 arranged in sequence, and the first connecting shaft 3211 and the fourth connecting shaft 3214 keep synchronous movement, and are used to fix the first push block 311; the second connecting shaft 3212 and the third connecting shaft 3213 keep synchronous movement, and are used to fix the second push block 312. Further, a cylinder 322 is provided at one end of the connecting shaft 321, and the cylinder 322 is used to drive the connecting shaft 321 to shift vertically, including a first cylinder 3221 and a fourth cylinder 3224 provided on one side of the bottom plate 2, and a second cylinder 3222 and a third cylinder 3223 provided on the other side of the bottom plate 2, the first cylinder 3221 and the fourth cylinder 3224 are respectively used to drive the first connecting shaft 3211 and the fourth connecting shaft 3214 to shift vertically; the second cylinder 3221 and the third cylinder 3223 are respectively used to drive the second connecting shaft 3212 and the third connecting shaft 3213 to shift vertically; thus, the first push block 311 and the second push block 312 can be clamped under the drive of the cylinder 322, thereby closing the notch of the slot 121. Further, the driving assembly 32 also includes a buffer 324 provided at the other end of the connecting shaft 321, which plays a buffering role.

[0023] Furthermore, in order to control the opening and closing degree of the slot 121 to meet the needs of products of different specifications so that the products can be easily placed in the slot, the driving component 32 of the present application also includes a stroke limit component 323, which is provided with abutment between the cylinder 322 and the connecting shaft 321, including a connecting block 3231 and a first limit block 3232, the connecting block 3231 is used to connect the cylinder 322 and the connecting shaft 321, and maintain synchronous movement with the connecting shaft 321, and the side wall of the connecting block 3231 is provided with a limit groove, and the limit block 3232 is arranged at the limit groove, so that the connecting shaft 321 is horizontally displaced within the stroke range of the limit groove.

[0024] Furthermore, in order to facilitate the quick clamping of the sandblasting jig 1 , a plurality of second limit blocks 4 are arranged on the top of the bottom plate 2 , and the second limit blocks 4 are arranged around the frame 11 .

[0025] Furthermore, vertical plates 5 are provided on both lateral sides of the bottom plate 2 , and manual valves 6 are provided on the side walls of the vertical plates 5 .

[0026] When in use, the sandblasting jig 1 is placed in the clamping mechanism 3, the travel limit assembly 323 is adjusted, the manual valve 6 is opened, and the cylinder 322 is actuated to drive the first push block 311 and the second push block 312 to shift toward each other, so that the slot 121 is closed, and the product can be assembled on the slot 121; then the manual valve 6 is closed, the slot 121 is naturally opened, and the product is fixed on the slot 121; then the sandblasting jig 1 with the assembled product is taken out and sent to the sandblasting machine for operation. After the operation is completed, the sandblasting jig 1 is placed in the clamping mechanism 3 again, the manual valve 6 is opened, and the slot 121 is closed to take out the product. This cycle can achieve the effect of semi-automatic material collection and discharge, reduce manpower requirements, and improve production and processing efficiency.
