[0018] According to an embodiment of the present invention, a vacuum-type positioning fixture for clamping pieces is provided.

[0019] Please refer to the instruction manual appendix. Figure 1-5According to an embodiment of the present invention, a mass-production vacuum-type positioning fixture for clamping pieces includes a worktable body 1. Multiple clamping grooves 2 are evenly distributed on the worktable body 1, and each clamping groove 2 is provided with a clamping component 3. An adsorption channel 4 is formed in the middle of the bottom wall of each clamping groove 2. A first sealing groove 5 is formed on the bottom wall of the worktable body 1. A vacuum suction cup 6 is sealed to the bottom end of the worktable body 1. A first sealing strip 7 is provided on the upper surface of the vacuum suction cup 6, and the first sealing strip 7 cooperates with the first sealing groove 5. Buckles 8 are provided on the outer wall of the vacuum suction cup 6 and the worktable body 1. The vacuum suction cup 6 is connected to an external vacuum pump via a pipe.

[0020] In the above technical solution, by evenly arranging multiple clamping slots 2 and corresponding clamping components 3 on the workbench body 1, and cooperating with a unified vacuum suction cup 6, the positioning and adsorption fixation of a large batch of clamping products can be completed at one time, improving clamping and production efficiency. At the same time, the vacuum adsorption method is adopted, and multiple sealing structures such as the first sealing slot 5 and the first sealing strip 7, the second sealing slot 10 and the second sealing strip 34, and the third sealing slot 33 and the third sealing strip are set to effectively prevent gas leakage, ensure continuous and stable adsorption force, and avoid product displacement or detachment during processing, thereby improving processing accuracy and safety.

[0021] The vacuum suction cup 6, the adsorption channel 4, and the adsorption through hole 32 work together to form a stable suction channel; the buckle 8 not only facilitates the connection between the vacuum suction cup 6 and the worktable body 1, but also enhances the sealing performance.

[0022] In one embodiment, please refer to the appendix to the specification. Figure 1 , Figure 2 , Figure 3 and Figure 4 The bottom walls of the clamping grooves 2 on both sides of the adsorption channel 4 are provided with countersunk holes 9. A second sealing groove 10 is provided at the connection between the bottom wall of the clamping groove 2 and the worktable body 1. The clamping assembly 3 includes a positioning clamping seat 31. An adsorption through hole 32 that cooperates with the adsorption channel 4 is provided in the middle of the positioning clamping seat 31. A third sealing groove 33 is provided on the upper surface of the positioning clamping seat 31. A third sealing strip is provided in the third sealing groove 33. The product body 11 is placed on the positioning clamping seat 31. Furthermore, the inner top wall of the product body 11 is used in conjunction with the third sealing strip on the positioning clamping seat 31. The bottom wall of the positioning clamping seat 31 is provided with a second sealing strip 34, which is used in conjunction with the second sealing groove 10. The bottom wall of the positioning clamping seat 31 is provided with a limiting hole 35, and the two limiting holes 35 are used in conjunction with the countersunk hole 9 on the bottom wall of the clamping groove 2. The positioning clamping seat 31 is installed in the clamping groove 2 by passing countersunk bolts 36 sequentially through the countersunk hole 9 and the limiting hole 35. In use, after placing the product body 11 on the positioning clamping seat 31, the suction force of the vacuum suction cup 6 is delivered to the inner wall of the product body 11 by the adsorption channel 4 and the adsorption through hole 32, and the product body 11 is firmly adsorbed on the positioning clamping seat 31. When replacement and maintenance are required, the countersunk bolt 36 is unscrewed from the countersunk hole 9, and the positioning clamping seat 31 in the clamping groove 2 can be taken out and replaced.

[0023] Workflow: First, place each of the clamping product bodies 11 to be processed onto its corresponding positioning clamping seat 31. Start the external vacuum pump; negative pressure is applied to the top of the inner cavity of the product body 11 through the vacuum suction cup 6, the adsorption channel 4, and the adsorption through-hole 32. Utilizing the stable adsorption force formed by the multiple sealing structures, all product bodies 11 are firmly fixed, allowing for subsequent processing. After processing is complete, turn off the vacuum pump; the adsorption force disappears, and the product can be removed. When replacement or maintenance is required, first open the buckle 8, move the worktable body 1 out, then unscrew the countersunk bolt 36 from the countersunk hole 9, then take out the positioning clamp 31 from the clamping groove 2, and then place the new positioning clamp 31 into the corresponding clamping groove 2, ensuring that its second sealing strip 34 is embedded in the second sealing groove 10. Then, use the countersunk bolt 36 to pass through the countersunk hole 9 from below the worktable body 1 and screw it into the limiting hole 35 of the positioning clamp 31 to tighten and fix it. Then, move the worktable body 1 to the upper end of the vacuum suction cup 6, ensure that its first sealing strip 7 is aligned with the first sealing groove 5, and then lock the buckle 8.

[0024] It should be noted that the working principle of the vacuum suction cup 6 is well known to those skilled in the art, and therefore will not be described in detail.

[0025] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
