[0002] Numerical control cutting refers to the workpiece instructions (or programs) used to control machine tools or equipment, which is a new control method given in digital form. When processing cover plates, the cover plates are usually cut by numerical control cutting.

[0003] The utility model with the publication number CN218891477U proposes a positioning cutting device for cover plate processing, which includes a cutting machine tool body, a support plate and a cutting head. Among them, the support plate is arranged on the cutting machine tool body for supporting the cover plate in the vertical direction; the cutting head is slidably arranged on the cutting machine tool body and is located above the support plate for cutting the cover plate; it also includes an arched cover, a pressing and positioning component and a driving mechanism. Among them, the arched cover is arranged on the support plate and is coaxially arranged with the cutting head along the length direction of the support plate. By setting the pressing and positioning component, the driving mechanism can be adjusted to drive the two pressing and positioning components to move synchronously towards the middle. At this time, one end of the pressing and positioning component located inside the arched cover can squeeze the cover plate from both sides, and the cover plate moves towards the middle position under the extrusion of the pressing and positioning component. When both pressing and positioning components are tightly pressed on both sides of the cover plate, the cover plate is positioned to the middle position, which is convenient for subsequent cutting processing.

[0004] The device disclosed in the above utility model can only apply pressure to the top of the cover plate through two positioning frames to position the cover plate from above, with a single positioning direction and poor positioning effect. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a positioning cutting device for cover plate processing to solve the problem that the device disclosed in the above background art can only apply pressure to the top of the cover plate through two positioning frames to position the cover plate from above, with a single positioning direction and poor positioning effect.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A positioning cutting device for cover plate processing, including a base, on which a U-shaped support plate is installed, a cutting mechanism is arranged on the U-shaped support plate, a cover plate is placed on the base, and positioning mechanisms are arranged on both sides of the cover plate. The two positioning mechanisms are arranged facing each other. The positioning mechanism includes a U-shaped moving block slidably installed on the base, a hydraulic rod is connected to the U-shaped moving block, both sides of the U-shaped moving block are slidably connected with pressing rods, and L-shaped connecting plates are rotatably connected to the two pressing rods. The two L-shaped connecting plates are located outside the two pressing rods and are installed on the base.

[0007] Preferably, extension plates are installed on both sides of the base, and the U-shaped moving block and the hydraulic rod are located on the extension plates.

[0008] Preferably, moving grooves are formed on the extension plates and extend to the base. A limiting strip is installed at the bottom of the U-shaped moving block, and the limiting strip is adapted to the moving grooves.

[0009] Preferably, sliding grooves are formed on both sides of the U-shaped moving block near the opening. Connecting shafts are installed on the pressing rods on both sides of the U-shaped moving block, and the connecting shafts are slidably adapted in the corresponding sliding grooves.

[0010] Preferably, a threaded rod is threadedly connected to the U-shaped moving block, and a positioning block is installed at one end of the threaded rod close to the cover plate.

[0011] Preferably, a threaded hole is formed in the U-shaped moving block, and the threaded rod is threadedly adapted in the threaded hole.

[0012] Preferably, elastic sheets are installed on both the pressing rod and the positioning block.

[0013] The beneficial effects of the present utility model are as follows:

[0014] In the present utility model, by turning on the hydraulic rod, the output shaft of the hydraulic rod moves towards the center of the device, thereby driving the U-shaped moving block connected thereto to move synchronously. During the movement of the U-shaped moving block, the pressing rod slidably connected thereto rotates until the end of the pressing rod close to the cover plate rotates to be in close contact with the cover plate, and then the hydraulic rod is turned off. Thus, the four pressing rods on the two groups of positioning mechanisms apply downward pressure to the cover plate from both sides of the cover plate, thereby completing the fixation of the position of the cover plate. The device has a simple structure and occupies a small space. By fixing the cover plate with four pressing rods, the contact points and the pressing area between the positioning mechanism and the cover plate are effectively increased, further improving the positioning effect.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Referring to Figures 1-4 , a positioning and cutting device for cover plate processing, including a base 1, a U-shaped support plate 2 is installed on the base 1, a cutting mechanism 3 is arranged on the U-shaped support plate 2, a cover plate 4 is placed on the base 1, and positioning mechanisms 5 are arranged on both sides of the cover plate 4. The two positioning mechanisms 5 are arranged facing each other. The positioning mechanism 5 includes a U-shaped moving block 51 slidably installed on the base 1. A hydraulic rod 52 is connected to the U-shaped moving block 51. Pressing rods 53 are slidably connected to both sides of the U-shaped moving block 51. L-shaped connecting plates 54 are rotatably connected to the two pressing rods 53. The two L-shaped connecting plates 54 are located outside the two pressing rods 53 and are installed on the base 1.

[0022] When the device is in use, first place the cover plate 4 on the base 1, and then turn on the hydraulic rod 52. The output shaft of the hydraulic rod 52 moves towards the center of the device, thereby driving the U-shaped moving block 51 connected thereto to move synchronously. During the movement of the U-shaped moving block 51, the pressing rod 53 slidably connected thereto is driven to rotate until the end of the pressing rod 53 close to the cover plate 4 rotates to be in close contact with the cover plate 4, and then turn off the hydraulic rod 52. Thus, the four pressing rods 53 on the two positioning mechanisms 5 apply downward pressure to the cover plate 4 from both sides of the cover plate 4 respectively, thereby completing the fixation of the position of the cover plate 4. The device has a simple structure and small occupied space. The cover plate 4 is fixed by the four pressing rods 53, effectively increasing the contact points and the pressing area between the positioning mechanism 5 and the cover plate 4, and further improving the positioning effect.

[0023] Specifically, in this embodiment, extension plates 55 are installed on both sides of the base 1. The U-shaped moving block 51 and the hydraulic rod 52 are located on the extension plates 55. The arrangement of the extension plates 55 can increase the moving space of the U-shaped moving block 51 and the hydraulic rod 52 when the U-shaped moving block 51 moves and the hydraulic rod 52 works, so as to meet the operation requirements of the positioning mechanism 5.

[0024] Specifically, in this embodiment, a moving groove 56 is formed in the extension plate 55, and the moving groove 56 extends to the base 1. A limiting strip 57 is installed at the bottom of the U-shaped moving block 51, and the limiting strip 57 is adapted to the moving groove 56, so that the U-shaped moving block 51 can be slidably connected to the extension plate 55 and the base 1 through the adaptability of the limiting strip 57 and the moving groove 56. Thus, when the U-shaped moving block 51 moves, it can only move along the direction restricted by the moving groove 56, thereby avoiding the situation of deviation when the U-shaped moving block 51 moves.

[0025] Specifically, in this embodiment, sliding grooves 513 are formed on both sides of the U-shaped moving block 51 near the opening. Connecting shafts 58 are installed on the pressure rods 53 on both sides of the U-shaped moving block 51, and the connecting shafts 58 are slidably adapted in the corresponding sliding grooves 513, so that the pressure rods 53 can be slidably adapted to the U-shaped moving block 51 through the connecting shafts 58. When the U-shaped moving block 51 moves, it can drive the pressure rods 53 to rotate through the connecting shafts 58, thereby achieving the purpose of positioning the cover plate 4.

[0026] Specifically, in this embodiment, a threaded rod 59 is threadedly connected to the U-shaped moving block 51, and one end of the threaded rod 59 close to the cover plate 4 is installed on the positioning block 510, so that when the U-shaped moving block 51 moves, it can drive the threaded rod 59 threadedly connected thereto to move synchronously. Thus, pressure is exerted on the side surface of the cover plate 4 through the positioning block 510 installed on the threaded rod 59, thereby fixing the positions of both sides of the cover plate 4 and further improving the stability of fixing the cover plate 4.

[0027] Specifically, in this embodiment, a threaded hole 511 is formed in the U-shaped moving block 51, and the threaded rod 59 is threadedly adapted in the threaded hole 511, so that the threaded rod 59 can be threadedly adapted to the U-shaped moving block 51 through the threaded hole 511. When the size of the cover plate 4 changes, the staff can adjust the distance between the positioning block 510 and the cover plate 4 by rotating the threaded rod 59, so that the device can meet the positioning requirements of cover plates 4 of different specifications.

[0028] Specifically, in this embodiment, elastic pieces 512 are installed on both the pressure rod 53 and the positioning block 510. When the pressure rod 53, the positioning block 510 and the cover plate 4 are in contact, the elastic pieces 512 will first come into contact with the cover plate 4, thereby increasing the friction between the pressure rod 53, the positioning block 510 and the cover plate 4 through the elastic pieces 512, improving the positioning effect, and at the same time providing protection for the cover plate 4 to avoid damage to the cover plate 4 during the positioning process.

[0029] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
