Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting of circular tubes, in particular to a clamping and fixing device for laser cutting of circular tubes with different diameters. Background Art

[0002] Laser cutting technology plays a very important role in industrial manufacturing systems. Many metal materials, regardless of their hardness, can be cut without deformation. Laser cutting forming technology is also widely used in the field of non-metallic materials. It can not only cut materials with high hardness and high brittleness, such as silicon nitride, ceramics, quartz, etc.; it can also cut and process flexible materials, such as cloth, paper, plastic plates, rubber, etc., such as using lasers for clothing cutting. Among them, in the process of laser cutting of round tubes, effective fixation of materials is essential, but the traditional fixing method is generally complicated and lacks flexible adjustment measures, which is not conducive to ensuring the operation effect and efficiency.

[0003] As disclosed in the authorization announcement number CN214558229U, a clamping and fixing device for laser cutting of circular tubes of different diameters includes a bottom plate and a spring, a fixed frame is fixed on the bottom plate, and a rotating shaft is fixed on the bearing of the fixed frame, and the bottom plate is connected to the pulley, and the pulley bearing is fixed on the movable frame, the fixed plate is connected to the rotating rod through a columnar shaft, the spring is fixed on the movable frame, and a horizontal plate is fixed on the spring, and a vertical rod is fixed on the horizontal plate, and the vertical rod is connected to the convex teeth, and the convex teeth are fixed on the bottom plate. The clamping and fixing device for laser cutting of circular tubes of different diameters adopts a top-up mechanism in combination with an adjustable limit mechanism to fix the circular tube, which can ensure that the centers of the two ends of the circular tube after fixation are in the same plane, and can also fix pipes of different sizes, and can realize automatic rotation of the pipes through the motor drive, to ensure the smooth progress of the cutting process. However, the utility model lacks convenient vertical and lateral control measures, and is not convenient for adapting to different working environment requirements and flexible adjustment of the clamping and fixing points. To this end, we propose a clamping and fixing device for laser cutting of circular tubes of different diameters, which solves the vertical and lateral adjustment problems of the device, improves the use flexibility of the device, and expands the scope of application of the device. Utility Model Content

[0004] The utility model aims to provide a clamping and fixing device for laser cutting of circular tubes with different diameters, so as to solve the problems raised in the above-mentioned background technology.

[0008] Preferably, the lateral adjustment mechanism includes a moving block, a threaded hole, a smooth round through hole, a bidirectional threaded rod, a limit section, a limit slide rod, a fixed mounting seat and a reciprocating motor. One side of the moving block is fixedly connected to the fixed block, and the moving block is provided with a threaded hole and a smooth round through hole.

[0009] Preferably, the bidirectional threaded rod passes through the threaded hole and is threadedly connected, a limited position section is arranged in the middle of the bidirectional threaded rod, the limit sliding rod passes through the round through hole and both ends are fixedly mounted on one side of the fixed mounting seat.

[0010] Preferably, one end of the bidirectional threaded rod is fixedly mounted on one side of the fixed mounting seat, and the other end thereof is fixedly connected to the output end of the reciprocating motor, and the reciprocating motor is fixedly mounted on the other side of the fixed mounting seat.

[0011] Preferably, the lifting mechanism comprises a hydraulic lifting column, a servo cylinder, a bottom plate and a fixed platform, the top end of the hydraulic lifting column is fixedly connected to the bottom end of the fixed mounting seat, and the bottom end thereof is fixedly mounted to the top end of the bottom plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The clamping and fixing device is convenient for laser cutting of circular tubes of different diameters. The servo oil cylinder arranged by the lifting mechanism drives the hydraulic lifting column to work, thereby driving the lateral adjustment mechanism and the clamping and fixing mechanism to perform synchronous lifting and lowering.

[0015] This clamping and fixing device is convenient for laser cutting of circular tubes of different diameters. The reciprocating motor provided by the lateral adjustment mechanism drives the bidirectional threaded rod to rotate, thereby driving the moving block connected to the bidirectional threaded rod to move. Since the two moving blocks are symmetrically installed on the bidirectional threaded rod, when the threaded rod rotates, the two moving blocks also symmetrically close to the middle or open to both ends, so as to flexibly adjust the clamping distance for tubes of different lengths. By rotating the adjusting bolt provided by the clamping and fixing mechanism, the first clamping claw and the second clamping claw are driven to move up and down, thereby achieving the clamping and fixing effect of tubes of different diameters. The spring group installed between the first clamping claw and the second clamping claw and the wear-resistant and anti-skid layer provided on one side of the second clamping claw can further improve the clamping and fixing effect of the tube, and at the same time, the vibration impact of the tube on the device during the cutting process is reduced, thereby extending the service life of the device.

[0025] In this embodiment, preferably, the lateral adjustment mechanism includes a moving block 200, a threaded hole 201, a smooth round through hole 202, a bidirectional threaded rod 203, a limit section 204, a limit slide rod 205, a fixed mounting seat 206 and a reciprocating motor 207, and one side of the moving block 200 is fixedly connected to the fixed block 100, and the moving block 200 is provided with a threaded hole 201 and a smooth round through hole 202.

[0026] In this embodiment, preferably, the bidirectional threaded rod 203 passes through the threaded hole 201 and is threadedly connected, a limited position section 204 is set in the middle of the bidirectional threaded rod 203, and the limiting sliding rod 205 passes through the light round through hole 202 and both ends are fixedly installed on one side of the fixed mounting seat 206.

[0027] In this embodiment, preferably, one end of the bidirectional threaded rod 203 is fixedly mounted on one side of the fixed mounting seat 206 , and the other end thereof is fixedly connected to the output end of the reciprocating motor 207 , and the reciprocating motor 207 is fixedly mounted on the other side of the fixed mounting seat 206 .
