DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described 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 the embodiments.

[0031] Reference Figures 1 to 6 , a cutting fixture for a high-precision parts laser cutting table, comprising:

[0032] Cutting table 1; universal adjustment ball 2, movably mounted above the cutting table 1, and a tubular fixing ring 3 is movably sleeved on the surface of the universal adjustment ball 2, the bottom of the tubular fixing ring 3 is fixed to the top of the cutting table 1 by multiple fixing frames 4, which plays a role in supporting the universal adjustment ball 2 without affecting the free rotation of the universal adjustment ball 2.

[0033] An annular fixing plate 5 is fixedly installed on the top of the cutting table 1. A gear plate 6 is rotatably installed on the side of the annular fixing plate 5 away from the universal adjustment ball 2, and the gear plate 6 is movably connected to the universal adjustment ball 2; a support ring 20 is movably clamped in the annular fixing plate 5, and an annular groove 21 is provided on the surface of the support ring 20, and the annular groove 21 is slidably connected to the annular fixing plate 5, which supports the gear plate 6 so that the gear plate 6 can rotate normally.

[0034] The universal adjustment assembly is used to control the universal adjustment ball 2 to rotate on the tubular fixing ring 3; the universal adjustment assembly includes an adjustment shaft 7 that is movable through the surface of the gear plate 6, and the end of the adjustment shaft 7 is fixed to the universal adjustment ball 2. A first sliding hole 8 is provided on the surface of the gear plate 6, and the first sliding hole 8 is slidably connected to the adjustment shaft 7. A driving gear 18 is rotatably installed on the surface of the annular fixing plate 5, and the driving gear 18 is engaged with the gear plate 6. A driving motor 19 for driving the driving gear 18 to rotate is fixedly installed on the other side of the annular fixing plate 5. The driving motor 19 is started to control the driving gear 18 to rotate, and then drives the gear plate 6 engaged therewith to rotate. The universal adjustment ball 2 can be driven to rotate by utilizing the engagement between the first sliding hole 8 on the gear plate 6 and the adjusting shaft 7.

[0035] A second sliding hole 9 is provided on the surface of the adjusting shaft 7, and a tubular rectangular frame 10 is slidably connected in the second sliding hole 9. An electric telescopic rod 11 is fixedly installed on the surface of the gear plate 6 for driving the tubular rectangular frame 10 to move radially along the first sliding hole 8. When the electric telescopic rod 11 is started, the tubular rectangular frame 10 is pushed to move, and by sliding in the second sliding hole 9 on the adjusting shaft 7, the adjusting shaft 7 can be pushed to move in the first sliding hole 8, thereby driving the universal adjusting ball 2 to rotate.

[0036] The clamping assembly is installed on the side of the universal adjustment ball 2 away from the gear plate 6. The clamping assembly includes a cylindrical fixed cover 12 fixedly mounted on the surface of the universal adjustment ball 2. An electric push rod 13 fixedly mounted on the surface of the universal adjustment ball 2 is provided in the cylindrical fixed cover 12. The driving end of the electric push rod 13 is fixedly mounted with a piston 14, and the piston 14 is airtightly connected to the cylindrical fixed cover 12. Here, since the end of the cylindrical fixed cover 12 is a plane and the surface of the universal adjustment ball 2 is an arc surface, there is a gap at the connection between the cylindrical fixed cover 12 and the universal adjustment ball 2. The gap can ensure the normal movement of the piston 14 in the cylindrical fixed cover 12.

[0037] The surface of the cylindrical fixed cover 12 is symmetrically fixed with a gate-shaped rectangular pipe 15, and the two gate-shaped rectangular pipes 15 are air-tightly connected to a rectangular rod 16 at one end away from the cylindrical fixed cover 12. The two rectangular rods 16 extend to the end outside the gate-shaped rectangular pipe 15 and are removably installed with a clamping plate 17. After the high-precision parts are placed between the two clamping plates 17, the electric push rod 13 is started to control the piston 14 to move in the cylindrical fixed cover 12, squeezing the gas inside into the two gate-shaped rectangular pipes 15, pushing the two rectangular rods 16 to drive the two clamping plates 17 to move toward each other until the two clamping plates 17 are against the high-precision parts, thereby achieving the clamping and fixation of the high-precision parts.

[0038] Furthermore, the gear plate 6 is in contact with the surface of the universal adjustment ball 2, and the distance from the center of the gear plate 6 to the center of the universal adjustment ball 2 is smaller than the distance from the center of the gear plate 6 to the center of the tubular fixing ring 3, so that the universal adjustment ball 2 will not be separated between the tubular fixing ring 3 and the gear plate 6, while also ensuring that the universal adjustment ball 2 can rotate freely.

[0039] Furthermore, a connecting assembly is provided between the two splints 17 and the corresponding rectangular rods 16, and the connecting assembly includes a connecting frame 22 fixedly mounted on the surface of the splint 17, and the connecting frame 22 is slidably sleeved on the surface of the rectangular rod 16, and a bolt 23 is threadedly connected between the connecting frame 22 and the rectangular rod 16. A threaded groove 24 is provided on the surface of the rectangular rod 16, and the threaded groove 24 is threadedly connected or separated from the bolt 23. By screwing out and screwing in the bolt 23, the splint 17 and the rectangular rod 16 can be disassembled and assembled, thereby facilitating the replacement of the splint 17.

[0040] The working principle of the present invention is:

[0041] When in use, first place the high-precision part between the two clamping plates 17, then start the electric push rod 13 to control the piston 14 to move in the cylindrical fixed cover 12, squeezing the gas inside into the two door-shaped rectangular pipes 15, pushing the two rectangular rods 16 to drive the two clamping plates 17 to move towards each other until the two clamping plates 17 are against the high-precision part, thus achieving the clamping and fixing of the high-precision part;

[0042] When adjusting the angle of the workpiece, the driving motor 19 is started to control the driving gear 18 to rotate, and then the gear plate 6 engaged with it is driven to rotate. The first sliding hole 8 on the gear plate 6 is engaged with the adjusting shaft 7, which can drive the universal adjustment ball 2 to rotate;

[0043] At the same time, the electric telescopic rod 11 can be started to push the tubular rectangular frame 10 to move, and by sliding the electric telescopic rod 11 in the second sliding hole 9 on the adjusting shaft 7, the adjusting shaft 7 can be pushed to move in the first sliding hole 8, thereby driving the universal adjustment ball 2 to rotate, so as to achieve a universal adjustment effect on the angle of high-precision parts and improve the use effect of the device.

[0044] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are common means well known to those skilled in the art.

[0045] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
