A mounting box 2 is provided on the top of the base 1, and a longitudinal moving assembly for driving the mounting box 2 to move is provided on the base 1. A placement plate 3 for placing products is fixedly provided on the top of the mounting box 2, and a hydraulic cylinder 4 is fixedly provided in the mounting box 2. A push plate 5 is provided on the output end of the hydraulic cylinder 4, and the push plate 5 is slidably arranged in the mounting box 2. A plurality of clamping assemblies are detachably provided on the side of the push plate 5 away from the hydraulic cylinder 4, and a plurality of through holes 6 for one end of the clamping assembly to pass through are provided on the placement plate 3; the screw locking assembly is mounted on the top of the base 1, and is used to lock the screws of the products on the placement plate 3; the positioning assembly is arranged at the end of the placement plate 3, and is used to position the products. During operation, according to the size of the product, one end of the clamping assembly is passed through the through hole 6 on the placement plate 3 and then connected to the push plate 5. In the present embodiment, one end of the clamping assembly is threadedly connected to the push plate 5, and a plurality of threaded holes are provided on the push plate 5, each of which corresponds one by one to the through hole 6 on the mounting plate. After the clamping assembly is installed, the product is placed on the placement plate 3 and positioned by the positioning assembly. Subsequently, the hydraulic cylinder 4 is started, and the hydraulic cylinder 4 drives the clamping assembly to press the product on the placement plate 3 to prevent the product from moving. Then, the screw locking assembly is started to lock the screws on the product on the placement plate 3. For products of different sizes, workers can adjust the position of the threaded connection between the clamping assembly and the push plate 5 according to the shape of the product, so that the clamping assembly can be pressed on a better force point when pressing the product. It has strong adaptability and only requires one set of clamps to be applied to products of various models and sizes.

[0020] like Figure 1 As shown in FIG. 3 , further, each clamping assembly includes: a connecting rod, one end of which is threadedly connected to the top of the push plate 5, and the other end of the connecting rod is provided with a pressing block 7 after passing through the through hole 6. When the product is placed on the placement plate 3, the hydraulic cylinder 4 drives the push plate 5 to move downward, and during the downward movement of the push plate 5, the multiple connecting rods on it are driven to move downward, so that the pressing block 7 on the connecting rod is pressed on the product to limit the movement of the product.

[0021] like Figure 1 —3, further, the connecting rod includes: a sleeve 8, one end of the sleeve 8 is fixedly connected to the output end of the hydraulic cylinder 4, the other end of the sleeve 8 is threadedly connected to a telescopic rod 9, and the end of the telescopic rod 9 away from the sleeve 8 is connected to the pressing block 7. Different products have different thicknesses, and workers can adjust the entire connecting rod according to the thickness of the product. During adjustment, the telescopic rod 9 is rotated according to the thickness of the product, so that the telescopic rod 9 is screwed into or out of the sleeve 8, so that the pressing block 7 can achieve a better pressing effect on the product without being pressed too tight or too loose.

[0022] like Figure 1 , 3 As shown in Figure 4, further, the screw locking assembly includes: two telescopic cylinders 10, the two telescopic cylinders 10 are symmetrically arranged on both sides of the base 1, the output ends of the two telescopic cylinders 10 are vertically upward and are provided with a mounting block 11, a screw locking machine body 12 is slidably provided on the side wall of the mounting block 11, and the mounting block 11 is also provided with a lateral moving assembly that drives the screw locking machine body 12 to move along the length direction of the mounting block 11. Specifically, in this embodiment, the telescopic cylinder 10 is arranged on the top of the base 1, and the two telescopic cylinders 10 are respectively located on both sides of the mounting box 2. When screwing the product on the placement plate 3, the telescopic cylinder 10 is started, and the telescopic cylinder 10 drives the mounting block 11 to a suitable height, and then the screw locking machine body 12 works to tighten the screws on the product, and the lateral moving assembly can drive the screw locking machine body 12 to move to the desired position.

[0023] like Figure 4 As shown, further, the lateral movement assembly includes: a first screw rod 13, a first slide groove is provided on the mounting block 11, a first slider 14 is slidably provided in the first slide groove, the first screw rod 13 is rotatably arranged in the first slide groove and is threadedly connected with the first slider 14, one end of the first screw rod 13 is provided with a first motor 15 driving it to rotate after passing through the first slide groove, and one side of the first slider 14 is fixedly connected with the screw locking machine body 12. When the screw locking machine body 12 needs to be moved, the first motor 15 is started, the first motor 15 drives the first screw rod 13 to rotate, and the rotation of the first screw rod 13 drives the first slider 14 threadedly connected thereto to move along the length direction of the first slide groove, so that the screw locking machine body 12 is driven by the first slider 14 to move along the length direction of the mounting block 11.

[0024] like Figure 1 and 3As shown, further, the longitudinal moving assembly includes: a second screw rod 16, a second slide groove is provided at the top of the base 1, a second slider 17 is provided in the second slide groove, the second screw rod 16 is horizontally and rotatably arranged in the second slide groove and is threadedly connected with the second slider 17, the top of the second slider 17 is fixedly connected with the bottom of the installation box 2, and a second motor 18 is provided to drive the second screw rod 16 to rotate after one end of the second screw rod 16 passes through the second slide groove. When the installation box 2 is driven to move, the second motor 18 is started, and the second motor 18 drives the second screw rod 16 to rotate. The rotation of the second screw rod 16 drives the second slider 17 threadedly connected thereto to move along the length direction of the second slide groove, so that the second slider 17 drives the installation box 2 to move on the top of the base 1. Through the cooperation of the longitudinal moving assembly and the lateral moving assembly, the screw locking machine body 12 on the installation block 11 can perform screw locking operations on any position of the product on the placement plate 3.

[0025] like Figure 1 —2, further, the positioning assembly includes: a positioning bar 19, the positioning bar 19 is arranged at one end of the placement plate 3, and a limiting bar 20 is arranged on the side wall of the positioning bar 19, and the limiting bar 20 is perpendicular to the positioning bar 19. When placing the product on the placement plate 3, one side of the product is pressed against the side wall of the limiting bar 20, and then the product is moved so that the other side of the product is pressed against the limiting bar 20, and then the product can be pressed, so as to position the product, which is convenient for batch processing of the product.

[0026] like Figure 1 and 3 As shown, further, a cotton pad 21 is provided at the bottom of the pressing block 7. When the pressing block 7 moves downward following the connecting rod to press the product, the cotton pad 21 can protect the surface of the product, thereby preventing the pressing block 7 from crushing the product or causing an indentation on the surface of the product when pressing on the product, and effectively protecting the appearance of the product.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
