[0025] like Figures 1 to 6 As shown, an embodiment of the present invention provides a double-sided pressing jig tooling for a flat-panel frame speaker mesh foam, comprising a jig support base 1, both sides of the bottom of the jig support base 1 are fixedly connected with tooling support vertical plates 2, a product flat panel 3 is placed on the top of the jig support base 1, and a limiting mechanism is arranged on the jig support base 1 at the outer side of the product flat panel 3, the limiting mechanism is used for the initial positioning of the product flat panel 3 on the jig support base 1, and a cylinder single-acting double-sided pressing mechanism 6 is installed on both sides of the jig support base 1 and at the speaker hole position of the product flat panel 3. When in use, the product flat panel 3 is placed on the jig support base 1, and the product flat panel 3 is initially positioned by the limiting mechanism to ensure the fixed position, and then the speaker hole position of the product flat panel 3 is clamped and fixed by the cylinder single-acting double-sided pressing mechanism 6, so that the product flat panel 3 is firmly fixed, the position of the product flat panel 3 is prevented from being displaced, and the product yield and processing efficiency are improved.

[0026] In this embodiment, if Figure 1 and Figure 2As shown, the limiting mechanism includes a limiting block 5, and a plurality of limiting blocks 5 are distributed around the top of the jig support base 1. A limiting block mounting groove 101 for accommodating the limiting block 5 is provided on the top of the jig support base 1. A first waist-shaped sink hole 501 is provided on the limiting block 5 to penetrate the limiting block. The limiting block 5 and the jig support base 1 are fixedly connected by a first fixing screw 502 passing through the limiting block mounting groove 101. The thickness of the limiting block 5 is greater than the depth of the limiting block mounting groove 101. Through the thickness design of the limiting block 5, when the limiting block 5 is installed in the limiting block mounting groove 101, the top of the limiting block 5 protrudes from the upper surface of the jig support base 1. By arranging multiple limit blocks 5 around the jig support base 1, when the product plate 3 is placed on the top of the jig support base 1, the product plate 3 is placed on the inner side of the multiple limit blocks 5, which is used to perform preliminary limiting on the fixed position of the product plate 3, thereby ensuring the accuracy of the fixed position of the product plate 3 and the consistency of repeated clamping of the product plate 3. By arranging a first waist-shaped countersunk hole 501 on the limit block 5, the extension direction of the first waist-shaped countersunk hole 501 is along the outer side of the jig support base 1 toward its center. After loosening the first fixing screw 502, the position of the limit block 5 can be adjusted to adapt to the size of the product plate 3, which is highly practical.

[0027] In this embodiment, if Figure 1 and Figure 2 As shown, a flat jig support mechanism 4 adapted to the product flat plate 3 is disposed on the top of the jig support base 1 , and the flat jig support mechanism 4 is used for positioning the product flat plate 3 and supporting the structural surface.

[0028] In this embodiment, if Figure 3 As shown, the cylinder single-acting double-sided clamping mechanism 6 includes a base 601, an outer cavity mounting seat 602 fixedly connected to the top of the base 601, two moving blocks 603 slidably mounted in the outer cavity mounting seat 602, and a clamping block 605 fixedly connected to the top of the moving block 603. The two clamping blocks 605 are respectively located on the outer side and the inner side of the horn hole of the product plate 3. The cylinder single-acting double-sided clamping mechanism 6 also includes a transmission connection component 607, which is used to drive the two clamping blocks 605 to move synchronously to clamp or release. The base 601 is fixedly connected to one side. A support mounting seat 609 is connected, and the support mounting seat 609 is fixedly connected to the bottom of the fixture support base 1. In the initial state, the two clamping blocks 605 are in a loose state. After the product plate 3 is initially positioned by the limiting mechanism, the transmission connection component 607 is controlled to work, so that the transmission connection component 607 drives the two clamping blocks 605 to move and clamp. The two clamping blocks 605 are respectively clamped on the outer and inner foams of the speaker hole of the product plate 3, thereby realizing double-sided clamping of the product plate 3, greatly improving the stability of the clamping and fixing, and ensuring the accuracy of the fixed position.

[0029] In this embodiment, if Figure 4 As shown, the transmission connection assembly 607 includes a power vertical telescopic cylinder 6071 fixedly installed at the bottom of the base 601, the output end of the power vertical telescopic cylinder 6071 penetrates into the base 601 and is fixedly connected with a connecting block 6072, the bottom of the moving block 603 is fixedly connected with a driving block 604 placed in the base 601, and both sides of the two ends of the connecting block 6072 and the driving block 604 are provided with a linkage rod 6073, and the two ends of the linkage rod 6073 are respectively connected to the connecting block 6072 and the driving block 604 through a rotating shaft. It drives the connecting block 6072 to rise and fall vertically. When the connecting block 6072 is raised and lowered, it drives the linkage rod 6073 to adjust its position synchronously. The linkage rod 6073 drives the driving block 604 connected thereto to move. The driving block 604 drives the moving block 603 and the clamping block 605 to move, thereby realizing the clamping and loosening actions of the two clamping blocks 605. When the power vertical telescopic cylinder 6071 drives the connecting block 6072 to rise, the two clamping blocks 605 are in a loosening action. When the power vertical telescopic cylinder 6071 drives the connecting block 6072 to descend, the two clamping blocks 605 are in a loosening action.

[0030] In this embodiment, the powered vertical telescopic cylinders 6071 in the multiple groups of cylinder single-acting double-sided pressing mechanisms 6 are all connected to the same foot-operated pneumatic valve through an air pipe, which is used to control the air supply switch of the powered vertical telescopic cylinders 6071.

[0031] In this embodiment, if Figure 4 As shown, both sides of the top of the power vertical telescopic cylinder 6071 are fixedly connected with fixed blocks 6074 extending into the base 601, and the opposite sides of the two fixed blocks 6074 are fixedly connected with two sliding guide rods 6075, and the end of the sliding guide rod 6075 away from the fixed block 6074 is fixedly connected with a stopper, and a guide slide hole 6041 is provided on the driving block 604 for the sliding guide rod 6075 to pass through. When the linkage rod 6073 pushes the driving block 604 to move, the driving block 604 slides on the sliding guide rod 6075 through the guide slide hole 6041, so that the driving block 604 moves horizontally, which is used to drive the clamping block 605 to clamp and release.

[0032] In this embodiment, if Figure 6 As shown, a lower movable limit groove 6022 is horizontally opened at the bottom of the outer cavity mounting seat 602 for the driving block 604 to pass through, and upper movable limit grooves 6021 are symmetrically opened on both sides of the top of the outer cavity mounting seat 602 for the top of the moving block 603 to pass through. The lower movable limit groove 6022 is used to limit the moving range of the driving block 604, and the upper movable limit groove 6021 is used to limit the moving range of the moving block 603, so as to avoid the driving block 604 and the moving block 603 from moving out of position.

[0033] In this embodiment, if Figure 4 and Figure 6 As shown, the inner bottom end of the outer cavity mounting seat 602 is located on both sides of the lower movable limit groove 6022 and is fixedly connected with a cylindrical guide rail 608, and the bottom of the moving block 603 is provided with a guide rail groove 6032 that cooperates with the cylindrical guide rail 608 to slide. During the movement of the moving block 603, the moving block 603 slides on the cylindrical guide rail 608 through the guide rail groove 6032, so that the moving block 603 slides smoothly in the outer cavity mounting seat 602, thereby improving the smoothness of the movement of the moving block 603.

[0034] In this embodiment, if Figure 5 As shown, a fixing hole 6031 is provided on the top of the movable block 603, and a second waist-shaped countersunk hole 6051 corresponding to the position of the fixing hole 6031 is provided on the clamping block 605. The second waist-shaped countersunk hole 6051 passes through the clamping block 605, and the clamping block 605 and the movable block 603 are connected and fixed by a second fixing screw 6052 that passes through the second waist-shaped countersunk hole 6051 and the fixing hole 6031. By loosening the second fixing screw 6052, the relative position of the clamping block 605 and the movable block 603 can be adjusted, thereby adjusting the distance between the two clamping blocks 605 when clamped, so as to adapt to the clamping of different wall thicknesses at the speaker hole of the paired product flat plate 3, and the applicability is high.

[0035] In this embodiment, if Figure 4 As shown, protective pads 606 are fixedly bonded to the opposite sides of the two clamping blocks 605. The protective pads 606 are preferably made of silicone material, but can also be other materials with better protection capabilities. When the two clamping blocks 605 are clamped, the protective pads 606 are in contact with the foam of the speaker hole of the product flat plate 3, which can reduce the risk of indentation and scratches, improve protection of the product, and improve product quality.

[0036] The technical solution provided by the present invention, when in use, first debug the clamping jig tooling, place the product plate 3 on the top of the jig support base 1, loosen the first fixing screw 502, adjust the position of the limit block 5, adjust the limit block 5 to a suitable position, then tighten the first fixing screw 502, lock the position of the limit block 5, according to the above steps, adjust the positions of multiple limit blocks 5 in place in sequence, then loosen the second fixing screw 6052, adjust the positions of the two clamping blocks 605, adjust the clamping blocks 605 to a suitable position, then tighten the second fixing screw 6052, lock the position of the clamping blocks 605, according to the above steps, adjust the clamping blocks 605 on the multiple groups of cylinder single-acting double-sided clamping mechanisms 6 in place in sequence, and complete the debugging work of the clamping jig tooling; When clamping the product plate 3, the product plate 3 is placed on the top of the support base 1 and placed inside a plurality of limit blocks 5 to initially limit the fixed position of the product plate 3, thereby ensuring the accuracy of the fixed position of the product plate 3 and the consistency of repeated clamping of the product plate 3. Then, the power vertical telescopic cylinder 6071 in the multiple groups of cylinder single-acting double-sided clamping mechanism 6 is controlled by the foot-operated pneumatic valve to work, so that the power vertical telescopic cylinder 6071 drives the connecting block 6072 to descend vertically, and drives the driving block 604 connected thereto to move through the linkage rod 6073, and the driving block 604 drives The movable block 603 and the clamping block 605 move to realize the clamping of the two clamping blocks 605. The two clamping blocks 605 are respectively clamped on the outer and inner foams of the speaker hole of the product flat plate 3. By fixing the adhesive protection pad 606 on the clamping end of the clamping block 605, the protection pad 606 is in contact with the foam of the speaker hole of the product flat plate 3, which can reduce the risk of indentation and scratches and improve the protection of the product. The present application realizes double-sided clamping of the product flat plate 3, greatly improves the stability of the clamping and fixing, ensures the accuracy of the fixed position, avoids the position deviation of the product flat plate 3, and improves the product yield and processing efficiency.
