Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to a laser cutting machine with intermittent equidistant feeding. Background Art

[0002] Laser cutting machine is a cutting machine made by laser cutting principle. Laser cutting machine can make the laser emitted by the laser pass through the optical path system and further focus into a high power density laser beam, and use the laser beam to cut the workpiece;

[0003] In the laser cutting machine disclosed in publication number CN202122044685.8, the workpiece to be processed is first placed on the machine tool, and the hydraulic cylinder is started to drive the telescopic rod to reciprocate, thereby driving the connecting mechanism, the connecting plate and the laser cutter to move, until the height of the laser cutter is lowered as much as possible on the basis of ensuring that other conditions remain unchanged, so as to reduce the diffusion of the laser, thereby improving the cutting accuracy, and the slider mechanism is used to reciprocate on the slide rail and the laser cutter itself moves horizontally on the connecting plate to complete the cutting of the workpiece plane;

[0004] However, the above scheme still has the following problems when in use: when in use, it is necessary to manually measure the length of the workpiece to be cut and mark it, and then place it on the work surface. After the placement is completed, the laser cutting machine is started for cutting. After the cutting is completed, the staff first stops the laser cutting machine, then removes the workpiece that has been cut on the work surface, and rearranges the workpiece to be cut. The operation is cumbersome and time-consuming, and the laser cutting machine needs to be started and shut down repeatedly and frequently, which can easily cause damage to the laser cutting machine and is not convenient for intermittent equidistant feeding. In addition, fine particles (dust) will be generated during the laser cutting process. A lot of dust generated after the cutting will remain on the laser cutting table, which will cause certain harm to the health of the staff.

[0005] Therefore, we proposed a laser cutting machine with intermittent equidistant feeding to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a laser cutting machine with intermittent equidistant feeding to solve the problem of the existing laser cutting machines on the market proposed in the above background technology. When in use, it is necessary to manually measure the length of the workpiece to be cut and mark it, and then arrange it on the work table. After the arrangement is completed, the laser cutting machine is started for cutting. After the cutting is completed, the staff first stops the laser cutting machine, then removes the workpiece that has been cut on the work table, and rearranges the workpiece to be cut. The operation is cumbersome and time-consuming, and the laser cutting machine needs to be started and shut down repeatedly and frequently, which can easily cause damage to the laser cutting machine and is not convenient for intermittent equidistant feeding. In addition, fine particles (dust) will be generated during the laser cutting process. A lot of dust generated after the cutting will stay on the laser cutting table, which will cause certain harm to the health of the staff.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a laser cutting machine with intermittent equidistant feeding, comprising a workbench, and electric telescopic rods are symmetrically fixed on the left and right sides of the top of the workbench, and a top frame is fixed on the top of the electric telescopic rods, and a mobile module is slidably connected to the top frame, and a laser cutting head is installed at the bottom of the mobile module;

[0008] It also includes: conveying rollers are symmetrically connected to the left and right sides of the top of the workbench through the bearings, and the bottom of the conveying rollers is connected to an intermittent rotating mechanism, and the conveying rollers are used to convey the processing parts at equal intervals;

[0009] The symmetrical bearings on the left and right sides of the movable module are connected with dust suction pipes, and the dust suction pipes are connected to the dust collecting box through connecting pipes, and the dust collecting box is installed on the top rear side of the top frame.

[0010] Preferably, the intermittent rotation mechanism is composed of a first pull rope, a vertical rod, a first torsion spring and a ratchet assembly, and the first pull rope is symmetrically fixed to the left and right sides of the bottom of the top frame, and the bottom of the first pull rope is connected to the vertical rod, and the vertical rod is symmetrically bearing-connected to the left and right sides inside the workbench, and at the same time, a first torsion spring is installed between the vertical rod and the workbench, so that after the first pull rope drives the vertical rod to rotate, the vertical rod will reverse the first torsion spring.

[0011] Preferably, the outer side of the top of the vertical rod is connected to the bottom of the conveying roller through a ratchet assembly, and the cross-section of the conveying roller is set to an "H" shape structure, and the conveying roller forms an intermittent rotation structure through the vertical rod and the ratchet assembly, so that after the vertical rod is rotated, the ratchet assembly drives the conveying roller to rotate in one direction.

[0012] Preferably, a second pull rope is symmetrically fixed on the left and right sides of the rear side of the bottom of the workbench, and the end of the second pull rope is connected to the half gear, and the half gear symmetrical bearings are connected to the left and right sides of the mobile module, and a second torsion spring is installed between the half gear and the mobile module, so that after the second pull rope drives the half gear to rotate, the second torsion spring will be reversed.

[0013] Preferably, the outer side of the half gear is meshed with a full gear, and a third torsion spring is installed between the full gear and the movable module, and the full gear is fixed to the outer side of the dust suction pipe, so that after the half gear rotates, it will intermittently rotate with the full gear, and after the full gear rotates, the third torsion spring will be reversed.

[0014] Preferably, the full gear forms a reciprocating rotation structure through the full gear and the third torsion spring, and the full gear drives the dust suction tube to form a swinging dust suction mechanism, so that the full gear drives the dust suction tube to reciprocate and absorb dust under the cooperation of the half gear and the third torsion spring.

[0015] Compared with the prior art, the intermittent equidistant feeding laser cutting machine of the utility model has the following beneficial effects: when in use, the processing parts can be intermittently and equidistantly conveyed through the intermittent rotation of the conveying roller, eliminating the tedious operation of manual measurement for cutting and manual feeding, and the smoke and dust generated during the cutting process can be absorbed in time to avoid being inhaled by the staff and affecting their health. The specific contents are as follows:

[0016] 1. When the electric telescopic rod drives the top frame to move upward, the top frame will pull the first pull rope, and the first pull rope will drive the vertical rod to rotate, thereby reversing the first torsion spring. After the vertical rod rotates, it will drive the conveying roller to rotate through the ratchet assembly. After the conveying roller rotates, the processed parts will be automatically and equidistantly conveyed to the bottom of the laser cutting head, and then the top frame drives the laser cutting head to move downward for cutting. When the top frame moves downward, the first pull rope is relaxed, and the first torsion spring will drive the vertical rod to rotate. After the vertical rod rotates, the ratchet assembly is in a non-engaged state, and the conveying roller will not be driven to rotate, so that the processed parts can be conveyed intermittently and equidistantly, without the need for manual length measurement and material loading, which is more convenient;

[0017] 2. When the laser cutting head is driven to move by the mobile module, the pull ropes on both sides will be pulled and relaxed respectively. After the pull rope is pulled, the half gear will be driven to rotate, and then the second torsion spring will be reversed. After the pull rope is relaxed, the second torsion spring in the reversed state will drive the half gear to rotate, and when the half gear rotates, it will intermittently mesh with the external full gear, so that the full gear rotates, thereby reversing the third torsion spring. When the half gear is not meshed with the full gear, the third torsion spring will drive the full gear to rotate, and then the full gear will reciprocate, thereby driving the dust suction pipe to swing synchronously, absorbing the smoke generated during the cutting process to prevent the smoke from being inhaled by the staff and affecting their health.
