Description

Technical Field

[0001] The invention relates to the field of laser cutting equipment, and in particular to a laser head water cooling device and method which are convenient for maintenance and vibration reduction. Background Art

[0002] Laser cutting is a process that uses a high-power density laser beam to irradiate the material and remove part of the material by melting, vaporizing or burning, thereby achieving the purpose of cutting.

[0003] In order to ensure that the laser cutting head can run for a long time, it needs to be cooled by a laser chiller. The laser chiller is an important auxiliary device of the laser equipment. Its main function is to circulate water to cool the laser generator to take away the heat generated by the laser during operation and ensure the normal operation of the laser equipment. The laser chiller will vibrate during operation. The existing equipment does not have a leveling function. The uneven ground will amplify the impact of vibration on the laser chiller and reduce the service life of the laser chiller. At the same time, the laser chiller body needs to dissipate heat when in use. The heat dissipation air enters through the dustproof net, which is fixed by bolts and needs to be cleaned regularly. The bolt fixing, cleaning and disassembly are time-consuming and laborious, so a device is urgently needed to solve the above problems. Summary of the invention

[0004] The object of the present invention is to provide a laser head water cooling device and method that is convenient for maintenance and vibration reduction, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a laser head water cooling device which is convenient for maintenance and shock absorption, comprising a body, a cooling fan is fixedly installed on the top of the body, a filtering mechanism for convenient filtering of incoming air is arranged on one side of the body, a hollow block is fixedly installed around the outside of the body, a control switch is fixedly installed on the top of the body, two control switches are arranged, a moving wheel for convenient movement of the body is fixedly installed on the bottom of the body, a screw is movably inserted at the lower end of the hollow block, the lower end of the screw movably extends to the outer side of the lower end of the hollow block, a connecting frame is fixedly installed between the screws, the connecting frame prevents the screw from rotating, a sleeve is sleeved on the outer side of the lower end of the screw, a first transmission wheel is movably installed at the bottom end of the hollow block, a transmission belt is arranged around the first transmission wheels, and a moving wheel is movably installed at the bottom end of the hollow block. There is a movable roller, and a power mechanism for driving the first transmission wheel to rotate is arranged inside the hollow block. When in use, the machine body and the laser head to be cooled are connected by a pipeline, and cooling water is injected through the machine body to keep the temperature of the laser head in a suitable state. Before use, the machine body is moved to the destination position through the moving wheel, and then the first transmission wheel is driven to rotate by the power mechanism using the transmission belt. Since the screw cannot rotate, the screw moves downward along the first transmission wheel until the lower end of the screw contacts the ground. This makes it convenient to fix the machine body and facilitate the stable use of the machine body. At the same time, when used in an uneven position, one side of the screw cannot contact the ground, making the machine body unstable. At this time, the sleeve on the outside of the screw that cannot contact the ground is rotated, so that the sleeve moves downward along the screw until the lower end of the sleeve contacts the ground, thereby ensuring that the machine body is in a stable state and preventing the impact of unstable vibration on the machine body.

[0006] Preferably, the power mechanism includes a worm wheel, a second transmission wheel, a motor and a worm, the second transmission wheel is movably embedded in the bottom end position inside the hollow block, the transmission belt is arranged around the outside of the second transmission wheel, the worm wheel is fixed at the top position of the second transmission wheel, the motor is fixed on the inner wall of the hollow block, and the worm is fixed at the output end position of the motor. When in use, the motor is started to drive the worm to rotate, thereby driving the worm wheel to rotate, so that the second transmission wheel rotates, and the first transmission wheel is driven to rotate through the transmission belt. Through the cooperation of the transmission belt, worm, worm wheel, motor, first transmission wheel and second transmission wheel, one motor can drive all the screws to move simultaneously, without the need to install multiple power sources, thereby reducing the use of power sources.

[0007] Preferably, the filter mechanism includes a trough body, a vent, an extrusion plate, a filter screen, a movable shaft, a limit block and an L-shaped block. The trough body is opened on one side of the machine body, and the vent is opened at the center of the trough body. The filter screen is slidably arranged inside the trough body, and the extrusion plate is slidably arranged inside the trough body to facilitate extruding the filter screen. The L-shaped block is fixed on one side of the machine body. Four L-shaped blocks are arranged and are respectively fixed at the four corners of the trough body. The movable shaft is movably embedded in the outside of the extrusion plate, and the limit block is fixed on the outside of the movable shaft. When the filter screen needs to be cleaned, the movable shaft is rotated at this time to drive the limit block to move so that the limit block is away from the inside of the L-shaped block. The extrusion plate can be moved to disassemble it, and then the filter screen can be disassembled without the need for installation and disassembly through bolts, which greatly facilitates the disassembly and cleaning of the filter screen.

[0008] Preferably, four first transmission wheels are provided and are respectively installed at the four corners of the bottom end of the hollow block.

[0009] Preferably, the screw rod passes through the center position of the first transmission wheel through a thread.

[0010] Preferably, one side of the movable roller is in close contact with the outer side of the transmission belt, so as to facilitate the transmission belt to be in a tensioned state.

[0011] Preferably, the worm wheel is meshed with the worm, and the motor is electrically connected to the control switch.

[0012] Preferably, there is a friction force between the movable shaft and the extrusion plate that hinders the rotation of the movable shaft.

[0013] Preferably, a method for using a laser head water cooling device that is convenient for maintaining and reducing vibration is as follows:

[0014] When in use, the machine body is connected to the laser head to be cooled through a pipeline, and cooling water is injected through the machine body to keep the temperature of the laser head in a suitable state. Before use, the machine body is moved to the destination position through the moving wheel, and then the first transmission wheel is driven to rotate by the transmission belt through the power mechanism. Since the screw cannot rotate, the screw moves downward along the first transmission wheel until the lower end of the screw contacts the ground. This makes it convenient to fix the machine body and facilitate stable use of the machine body. At the same time, when used in an uneven position, one side of the screw cannot contact the ground, making the machine body unstable. At this time, the sleeve outside the screw that cannot contact the ground is rotated to move the sleeve downward along the screw until the lower end of the sleeve contacts the ground, thereby ensuring that the machine body is in a stable state and preventing the impact of instability and increased vibration on the machine body.

[0015] The starting motor drives the worm to rotate, thereby driving the worm wheel to rotate, so that the second transmission wheel rotates, and the first transmission wheel is driven to rotate through the transmission belt. Through the cooperation of the transmission belt, the worm, the worm wheel, the motor, the first transmission wheel and the second transmission wheel, one motor can drive all the screws to move simultaneously, without installing multiple power sources, thereby reducing the use of power sources;

[0016] When the filter needs to be cleaned, rotate the movable shaft to drive the limit block to move so that the limit block is away from the inside of the L-shaped block, and then move the extrusion plate to remove it. Then the filter can be removed without the need for installation and disassembly with bolts, which greatly facilitates the disassembly and cleaning of the filter.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention moves the machine body to the destination position through the moving wheel, and then drives the first transmission wheel to rotate through the power mechanism using the transmission belt. Since the screw cannot rotate, the screw moves downward along the first transmission wheel until the lower end of the screw contacts the ground, which makes it convenient to fix the machine body and to use it stably. At the same time, when it is used in an uneven position, one side of the screw cannot contact the ground, making the machine body unstable. At this time, the sleeve outside the screw that cannot contact the ground is rotated to move the sleeve downward along the screw until the lower end of the sleeve contacts the ground, thereby ensuring that the machine body is in a stable state and preventing the influence of instability and increased vibration on the machine body.

[0019] 2. The present invention starts the motor to drive the worm to rotate, thereby driving the worm wheel to rotate, causing the second transmission wheel to rotate, and driving the first transmission wheel to rotate through the transmission belt. Through the cooperation of the transmission belt, worm, worm wheel, motor, first transmission wheel and second transmission wheel, one motor can drive all screws to move simultaneously, without the need to install multiple power sources, thereby reducing the use of power sources.
