Description

Technical Field

[0001] The invention relates to the technical field of laser cutting equipment, in particular to a laser cutting equipment used for rivet production. Background Art

[0002] Laser cutting machine is to focus the laser light emitted from the laser into a high power density laser beam through the optical path system. The laser beam irradiates the surface of the metal workpiece, causing the metal workpiece to reach the melting point or boiling point, and at the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, the material is eventually cut, thereby achieving the purpose of cutting the metal workpiece.

[0003] The laser cutting equipment in the prior art cannot clamp and position the workpiece during operation, and there will be a certain error in the cutting length. At the same time, it cannot be adjusted according to the size of the workpiece during use, and is not compatible with products of different lengths and outer diameters. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A laser cutting device for rivet production, comprising a platform, a vertical plate is fixedly installed on the top of the platform, a support arm on the top of the vertical plate is fixedly connected to a cylinder, and an output end of the cylinder is fixedly connected to a cutting mechanism; An adjusting mechanism, wherein the adjusting mechanism is fixedly mounted on the top of the platform; A fixing mechanism, the fixing mechanism is fixedly installed on the top of the platform, and the fixing mechanism and the adjusting mechanism are symmetrically arranged with the vertical plate as the center; The cam is provided with a toothed plate, the toothed plate ... The cam is fixedly connected to the end of the fixing plate near the through hole, and a rotating plate is fixedly connected to the outside of the fixing plate. The rotating plate is set as an arc-shaped plate and has elasticity. The rotating plate is located inside the through hole and the through opening. When working, the motor is connected to an external power supply, and the motor drives the fixing cylinder and the fixing rod to rotate. When the inner side of the rotating plate contacts the cylinder first, the rotating plate is stuck in the through hole, so that the fixing cylinder drives the cylinder to rotate together through the rotating plate, and then the cylinder drives the workpiece to rotate for laser cutting. When the outer arc surface of the rotating plate contacts the cylinder, the rotating plate is deformed by force, and the fixing cylinder rotates inside the cylinder. At this time, the fixing ring and the fixing cylinder are threadedly connected, so that the fixing ring drives the cylinder to move in a direction away from the motor, so that one end of a thinner workpiece can be clamped and fixed, so as to avoid the workpiece from being easily deformed during work. The rotating plate passes through the cylinder and the fixing cylinder through the through hole and the through opening, and the end of the fixing cylinder away from the fixing mechanism is fixedly connected with a motor.

[0005] One end of the cylinder away from the motor is fixedly connected with a clamping mechanism, and the clamping mechanism is evenly distributed on the cylinder. There are multiple through holes, and the multiple through holes are evenly distributed with the cylinder as the center.

[0006] Preferably, the clamping mechanism includes a fixed block, which is fixedly connected to the cylinder, and the inner wall of the fixed block is slidably connected with a round rod, which passes through the fixed block, and one end of the round rod away from the fixed block is fixedly connected with a clamping block, and the side of the clamping block close to the axial direction of the cylinder is set to an arc shape. When working, the fixing mechanism drives the workpiece to dock with the adjusting mechanism, the workpiece contacts the clamping block and generates a force, and the return spring is compressed by the force so that the clamping block and the workpiece are tightly fitted. Under the elastic action of the return spring, deformation and damage to the workpiece caused by excessive clamping force are avoided. By setting the clamping block to be an arc, when the workpiece contacts the clamping block, the workpiece is prevented from being damaged, and the end of the clamping block close to the round rod is fixedly connected with a return spring, and the end of the return spring away from the clamping block is fixedly connected to the fixed block, and the round rod is located in the middle of the return spring.

[0007] Preferably, the platform includes a base plate, a square groove is provided on the top of the base plate, and a motor is fixedly connected to the outer side of the base plate. When working, the external power supply of the motor works, and the motor drives the screw to rotate, so that the adjusting mechanism on the screw moves toward the direction of the fixing mechanism, thereby fixing the position and length of the workpiece, and the inner wall of the square groove is rotatably connected to the screw, the output end of the motor is fixedly connected to the screw, and the screw passes through the base plate.

[0008] Preferably, the fixing mechanism includes a limit plate, the limit plate is fixedly connected to the platform, the middle part of the limit plate is rotatably connected to the limit cylinder, the outer side of the limit cylinder is fixedly connected with a fixing seat, there are two fixing seats, the two fixing seats are symmetrically arranged on the limit cylinder, and the fixing seat is symmetrically arranged at one end close to the limit cylinder. When working, the workpiece is placed inside the limit cylinder, and under the elastic force of the spring plate, the connecting plate is in close contact with the workpiece. At this time, the motor drives the screw to rotate, so that the adjusting mechanism is close to the fixing mechanism, so that the clamping mechanism clamps the workpiece, and the screw further drives the adjusting mechanism to move away from the fixing mechanism, thereby driving the workpiece to move, and the support is symmetrically arranged and a ball, using rolling instead of sliding, so as to reduce the friction between the workpiece and the fixing mechanism, and reduce the loss of the workpiece. At the same time, the limit block is set as an arc-shaped protrusion. When the motor drives the workpiece to rotate, the limit block is set so that under the action of the contact force between the limit block and the workpiece, the limit cylinder rotates inside the limit plate to prevent the workpiece from slipping during rotation. The connecting plate is rotatably connected to the fixed seat, and the outer side of the connecting plate is fixedly connected with a spring plate, and the end of the spring plate away from the connecting plate is fixedly connected with the limit cylinder, and the end of the connecting plate away from the spring plate is fixedly connected with the limit block, and the opposite side of the connecting plate is fixedly connected with a support, and the inner part of the support is rotatably connected with a ball, and the limit block and the support are alternately arranged on the connecting plate.

[0009] Preferably, the cutting mechanism includes a connecting block, which is fixedly connected to the bottom of the cylinder, and a laser head is fixedly connected to the bottom of the connecting block. A positioning plate is fixedly connected to the outer side of the connecting block, and a positioning ring is fixedly connected to one end of the positioning plate away from the connecting block. When working, the cylinder drives the connecting block to move downward, so that the roller at the bottom contacts the workpiece. Under the elastic action of the compression spring, the connecting block continues to drive the laser head to move downward, so that the bottom of the laser head contacts the workpiece. The motor drives the fixed cylinder to rotate, thereby driving the workpiece to rotate for laser cutting. By setting the positioning ring, in a non-working state, the laser head is prevented from colliding with other objects, resulting in a deflection of the cutting direction, thereby resulting in a poor cutting effect. At the same time, by setting the roller, the laser head is prevented from moving downward excessively, and the side wall of the laser head is prevented from being damaged by friction, thereby improving the service life of the equipment. The laser head is located in the middle of the positioning ring, and a positioning rod is slidably connected to the bottom of the positioning ring. The end of the positioning rod away from the positioning ring is rotatably connected to the roller, and the end of the positioning ring close to the positioning rod is fixedly connected to the compression spring.

[0010] The present invention provides a laser cutting device for rivet production, which has the following beneficial effects: 1. The laser cutting equipment used for rivet production has a stepped groove at one end of the fixed plate away from the fixed rod. When the fixing mechanism drives the workpiece to dock with the adjusting mechanism, one end of the workpiece is located inside the stepped groove on the fixed plate. At this time, by setting the fixed plate, workpieces of different diameters can be cut to different lengths, so that the equipment can be suitable for workpieces of different lengths and diameters, thereby improving the applicability of the equipment.

[0011] Second, the laser cutting equipment used for rivet production has a threaded connection between a fixing ring and a fixing cylinder, so that the fixing ring drives the cylinder to move away from the motor, so that one end of a thinner workpiece can be clamped and fixed to avoid deformation of the workpiece during operation.

[0012] 3. The laser cutting equipment used for rivet production uses rolling instead of sliding through the support and the ball, so as to reduce the friction between the workpiece and the fixing mechanism and reduce the loss of the workpiece. At the same time, the limit block is set as an arc-shaped protrusion. When the motor drives the workpiece to rotate, the limit block is set so that under the action of the contact force between the limit block and the workpiece, the limit cylinder rotates inside the limit plate to prevent the workpiece from slipping during rotation.

[0013] Fourth, the laser cutting equipment used for rivet production uses a positioning ring to prevent the laser head from colliding with other objects when not in operation, causing the cutting direction to deflect and thus resulting in poor cutting effect. At the same time, by setting a roller, the laser head is prevented from moving downward excessively, and the side wall of the laser head is prevented from being damaged by friction, thereby increasing the service life of the equipment.

The through hole 28 and the through hole 26 are located on the same plane. The fixing ring 27 is threadedly connected to the fixed cylinder 25. The inner wall of the fixed cylinder 25 is fixedly connected with a fixing plate 29. The end of the fixing plate 29 away from the fixing rod 210 is a stepped groove. When the fixing mechanism 5 drives the workpiece to dock with the adjustment mechanism 2, one end of the workpiece is located inside the stepped groove on the fixing plate 29. At this time, by setting the fixing plate 29, workpieces of different diameters can be cut to different lengths, so that the equipment can be suitable for different lengths and diameters. The workpiece of the equipment is improved in applicability. One end of the fixed plate 29 near the through hole 26 is fixedly connected to a fixed rod 210.

The laser cutting is carried out by moving the laser head 62. By setting the positioning ring 64, when not working, it can prevent the laser head 62 from colliding with other objects, causing the cutting direction to deflect, thereby resulting in a poor cutting effect. At the same time, by setting the roller 66, the laser head 62 can be prevented from moving downward excessively, and the side wall of the laser head 62 can be prevented from being damaged by friction, thereby improving the service life of the equipment.

The motor 14 is connected to an external power supply and drives the screw 13 to rotate, so that the adjusting mechanism 2 on the screw 13 moves toward the direction of the fixing mechanism 5. The fixing mechanism 5 drives the workpiece to dock with the adjusting mechanism 2. The workpiece contacts the clamping block 244 and generates a force. The reset spring 243 is compressed by the force, so that the clamping block 244 is in close contact with the workpiece to clamp the workpiece. The screw 13 further drives the adjusting mechanism 2 to move away from the fixing mechanism 5, thereby driving the workpiece to move, and then fixing the position and length of the workpiece.

[0024] The motor 23 is connected to an external power source to work, and the motor 23 drives the fixed cylinder 25 and the fixed rod 210 to rotate. When the inner side of the rotating plate 211 first contacts the cylinder 22, the rotating plate 211 is stuck in the through hole 26, so that the fixed cylinder 25 drives the cylinder 22 to rotate together through the rotating plate 211, and then the cylinder 22 drives the workpiece to rotate for laser cutting. When the outer arc surface of the rotating plate 211 contacts the cylinder 22, the rotating plate 211 is deformed by force, and the fixed cylinder 25 rotates inside the cylinder 22. At this time, the fixing ring 27 is threadedly connected to the fixed cylinder 25, so that the fixing ring 27 drives the cylinder 22 to move away from the motor 23, so that one end of the thinner workpiece can be clamped and fixed to prevent the workpiece from being easily deformed during operation.
