[0030] 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 of the embodiments.

[0031] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0032] In some embodiments, Figure 1 , Figure 3 , Figure 6 , Figure 8 and Fig.10As shown, a positioning device for processing various small cover plates is provided, which mainly includes a vacuum suction cup 100 and a tooling body 200. The tooling body 200 is sealed and installed on the top of the vacuum suction cup 100. The vacuum suction cup 100 serves as a supporting base and can be connected to an external vacuum pumping device through a hose.

[0033] Specifically, a plurality of equally spaced positioning tables 202 are arranged in an array on the top of the tool body 200, forming a plurality of positioning tools, which can simultaneously process a plurality of similar small cover products, so as to solve the problem that the prior art can only realize single positioning processing of small cover products. Preferably, there are nine positioning tables 202 arranged in a nine-square grid.

[0034] In addition, if Figure 4 , Figure 5 , Figure 8 and Fig. 9 As shown, a vacuum groove 201 is opened at the bottom of the tooling body 200, an annular sealing strip 300 is embedded on the top of each positioning platform 202, and a plurality of through holes connected to the vacuum groove 201 are opened in the middle of each positioning platform 202, which are sealed and connected to the cover plate placed on the tooling body 200 through the annular sealing strip 300.

[0035] When in use, the vacuum groove 201 at the bottom of the tooling body 200 is evacuated, and the upper surface of the positioning platform 202 is adsorbed tightly on the positioning platform 202 through the negative pressure adsorption force formed between the annular sealing strip 300 and the surface of the cover plate, thereby ensuring the stability of the cover plate during processing and ensuring the accuracy of the cover plate processing.

[0036] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in order to facilitate the installation of the tool body 200, a square groove 101 is provided on the top of the vacuum suction cup 100, and a plurality of equally spaced fixing seats 102 are arranged in an array in the square groove 101, and a threaded hole 103 is provided on each of the fixing seats 102. The tool body 200 is locked and fixed in the corresponding threaded hole 103 by a fastening bolt 400.

[0037] The vacuum suction cup 100 and the tool body 200 are both square block structures, and the tool body 200 is smaller in shape than the vacuum suction cup 100 and can be integrally mounted on the vacuum suction cup 100. In order to ensure the sealing of the vacuum groove 201 between the vacuum suction cup 100 and the tool body 200, a sealing gasket is used at the connection between the vacuum suction cup 100 and the tool body 200 for sealing.

[0038] In some of the embodiments, Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, in order to facilitate the installation of the annular sealing strip 300 and ensure that the cover plate to be processed can be tightly adsorbed on the top of each positioning platform 202. On the top of each positioning platform 202, a first limiting boss 203, a second limiting boss 204 and a third limiting boss 205 are sequentially arranged coaxially from the outside to the inside.

[0039] Thus, an annular first sealing groove 206 is formed between the first limiting boss 203 and the second limiting boss 204, and an annular second sealing groove 207 is formed between the second limiting boss 204 and the third limiting boss 205. A first sealing strip 301 and a second sealing strip 302 are respectively embedded in the first sealing groove 206 and the second sealing groove 207, forming two relatively independent top sealing cavities that are respectively in contact with the bottom plate of the cover plate.

[0040] It should be noted that in order to achieve the connection between the two top sealed cavities and the vacuum groove 201 at the bottom of the tooling body 200 to form a negative pressure passage, a plurality of first through holes 2041 arranged at intervals are provided on the second limiting boss 204, and the bottoms of the first through holes 2041 are downwardly connected to the vacuum groove 201. Similarly, a plurality of second through holes 2051 arranged at intervals are provided on the third limiting boss 205, and the bottoms of the second through holes 2051 are downwardly connected to the vacuum groove 201.

[0041] When the empty groove 201 at the bottom of the tooling body 200 is evacuated, negative pressure is formed in the sealed cavity surrounded by the first sealing strip 301 and the second sealing strip 302 through the first through holes 2041 and the second through holes 2051, respectively, so that the cover plate is tightly adsorbed on the positioning platform 202, fully ensuring the stability of the cover plate adsorption on the positioning platform 202 and avoiding the cover plate from shifting during processing.

[0042] In some of the embodiments, Figure 1 , Figure 4 and Figure 5 As shown, corresponding to the first sealing groove 206 and the second sealing groove 207 at the top of the tool body 200, the annular sealing strip 300 is composed of two coaxially arranged first sealing strips 301 and second sealing strips 302.

[0043] Specifically, the first sealing strip 301 is detachably embedded in the first sealing groove 206 at the top of the positioning platform 202, and a peripheral negative pressure sealing area is formed between the first sealing strip 301 and the second sealing strip 302. The second sealing strip 302 is detachably embedded in the second sealing groove 207 at the top of the positioning platform 202, and an inner ring negative pressure sealing area is formed inside the second sealing strip 302.

[0044] In some of the embodiments, in order to ensure the stability of the tool body 200 when installed on the vacuum suction cup 100 and facilitate replacement and maintenance, a plurality of installation holes 209 arranged at intervals are respectively opened on the four sides of the tool body 200. The installation holes 209 are designed with a countersunk structure, and a plurality of fastening bolts 400 are respectively inserted from each installation hole 209, screwed downward and fixed in the corresponding threaded hole 103 on the top of the vacuum suction cup 100. The fastening bolts 400 can be hexagon socket screws.

[0045] In some of the embodiments, Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in order to achieve accurate positioning of the cover plate and to avoid the cover plate product being unable to be completely and accurately placed on the positioning platform 202, it is necessary to position the cover plate to be processed.

[0046] In order to achieve the above-mentioned purpose of precise positioning of the cover plate, the adopted solution is to open a number of pin holes 208 on the outside of each positioning platform 202 according to the structural shape and size of the cover plate, and a positioning column 500 is detachably installed in each pin hole 208, so as to position the cover plate product to be processed through the positioning column 500.

[0047] As a preferred embodiment, Figure 1 and Fig.10 As shown, for a square small-sized cover product, in order to achieve accurate positioning of the cover product, pin holes 208 are respectively opened at the diagonal positions of each positioning platform 202, and positioning columns 500 are detachably installed in the two pin holes 208, and the positioning columns 500 use pins.

[0048] In some of the embodiments, in order to ensure the service life of the positioning device used for processing various small cover plates and reduce equipment maintenance costs, high-strength materials are used to make the vacuum suction cup 100 and the tooling body 200. For example, stainless steel or aluminum alloy materials can be used as needed and integrally cast.

[0049] Combination Figure 1 , Figure 2 Figure 3 , Figure 4 and Figure 5As shown, the positioning device for processing various types of small cover plates has the following working principle: when operating, the operator first fills the two sealing grooves 206 and 207 on the top of the tool body 200 with sealing strips 301 and 302 respectively to prevent air leakage; then uses a number of fastening bolts 400 to lock and fix the tool body 200 to the corresponding position on the vacuum suction cup 100, places the part blank on the raised sealing ring on the top of the tool body 200, and uses the positioning column 500 to position the part, turns on the switch on the vacuum suction cup 100, and uses the external vacuum equipment to evacuate the vacuum groove 201, so that the part blank is tightly adsorbed on the tool body 200, and then the processing can begin, which ensures the stability of the cover plate during processing and further improves the accuracy of the cover plate processing.
