[0002] Laser processing is a processing technology that uses a high-power laser beam to cut, weld, surface treat, punch and micro-process workpieces. Due to its advantages such as small light spot, concentrated energy, small heat-affected zone and no contact with the workpiece, laser processing as an advanced manufacturing technology has been widely used in the fields of automobiles, electronics, electrical appliances, aviation, metallurgy, machinery manufacturing, etc.

[0003] Since laser processing has many advantages, processing of various tube materials has become a new application of laser processing. When processing tube materials, cutting is required at different positions on the tube materials so that they can be designed into tube materials with shapes or patterns.

[0004] In order to meet this demand of customers, several generations of laser cutting machines have been developed continuously, such as the first-generation laser cutting machine products (application number: 202210944297.1; name: a tube feeding mechanism and laser cutting machine) and the second-generation laser cutting machine products (application number: 202310123407.2; name: an automatic feeding and cutting all-in-one machine) that were developed and used in the early stage; these two generations of laser cutting machine products can effectively cope with long tubes of different diameters, which are of great effect on realizing automatic feeding and cutting and improving processing efficiency.

[0005] However, with the upgrading of industrial products, there is a demand for processing short tubes. Short tubes are obviously shorter than long tubes. At the same time, according to market analysis, short tubes are more widely used in industry. Therefore, based on the technology of the first two generations of laser cutting machines, the development of equipment suitable for laser cutting of short tube products is a problem that needs to be solved at present. Utility Model Content

DETAILED DESCRIPTION

[0030] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0031] This embodiment provides a laser cutting device, which is specially used for cutting short tubes, thereby filling the gap of the current lack of laser cutting devices for short tubes.

[0032] Specifically, the laser cutting equipment provided by the present solution includes a frame 100 and a feeding mechanism 200, a rotating clamping assembly 300 and a laser cutting assembly 400 arranged in the frame 100. The frame 100 is mainly composed of marble, especially the substrate as the mounting and fixing surface in the frame 100. The marble substrate is conducive to reducing the processing error and the installation error, and is conducive to improving the cutting accuracy of the short tube material; the feeding mechanism 200 is mainly used to dock with the external transmission structure (not shown), the transmission mechanism transports the formed short tube material to the feeding mechanism 200, the feeding mechanism 200 transfers the tube material to the rotating clamping assembly 300, the rotating clamping assembly 300 stably clamps the short tube material, and finally the laser cutting assembly 400 acts again to realize the cutting of the short tube material.

[0033] For ease of understanding, the composition of laser cutting equipment is introduced in detail below.

[0034] In this solution, the feeding mechanism 200 is an automatic feeding mechanism, which relies on an external transmission mechanism to input the tube material, and then automatically feeds it into the rotating clamping assembly 300.

[0035] The feeding mechanism 200 is composed of a feeding chute 210 and a material receiving assembly 220; the feeding chute 210 plays a docking role, one end of which is docked with an external conveying structure, so that the pipe material can be smoothly transported to the feeding chute 210; the other end of it is docked with the material receiving assembly 220, and the pipe material can smoothly enter the material receiving assembly after being guided by the feeding chute 210.

[0036] The loading slide 210 mainly includes a slide 211 and a limit bracket 212. The limit bracket 212 is installed on the slide 211 to form the loading slide 210. Specifically, the slide 211 is fixed on the base plate through a support frame 213. A vertical strip hole is provided on the support frame 213. The slide 211 is installed and fixed with the support frame 213 through the strip hole. By utilizing the characteristics of the strip hole, the slide 211 can be adaptively fine-tuned according to the situation. The slide 211 is L-shaped and there are two of them. The two slides 211 are arranged oppositely and at intervals. Each slide 211 is provided with the limit bracket 212 mentioned above. The limit bracket 212 is installed in conjunction with the slide 211 to form the loading slide 210 of this solution.

[0037] Optionally, considering that pipes of the same length may have different thicknesses, in order to enable the loading chute 210 to adapt to pipes of different diameters, the limit bracket 212 is designed as an adjustable structure, that is, the limit bracket 212 is installed on the slide 211 and can be adjusted, so that the loading chute 210 can adapt to pipes of different diameters.

[0038] In order to ensure the smooth sliding of the pipe material, the loading slideway 210 formed by the cooperation of the limit bracket 212 and the slide seat 211 has a high point and a low point; the high point and the low point are smoothly connected to make the loading slideway 210 inclined; the external transmission mechanism inputs the pipe material to the high point here, and then the pipe material slides to the low point along the inclined loading slideway 210 under the action of gravity. Through the design of the high and low points, the pipe material can be fed under the action of its own gravity, reducing the design of other auxiliary mechanisms, making the structure of the loading slideway 210 more concise.

[0039] After the pipe material slides to the low point, it will fall into the material receiving component 220; specifically, the material receiving component 220 is arranged below the loading slide 210; at the same time, the material receiving component 220 includes a material receiving seat 221 and a first power source 222; the first power source 222 drives the material receiving seat 221 to perform telescopic movement between the material receiving position and the material receiving position; the material receiving position is lower than the material receiving position and corresponds to the low point, and the telescopic path of the material receiving seat is inclined.

[0040] It can be understood that when the material receiving seat 221 is in the material receiving position, the pipe material slides freely and falls directly into the material receiving position through the high point and the low point; then the first power source 222 drives the material receiving seat 221 to extend and move upward at an angle, so that the material receiving seat 221 is pushed into the material receiving position, waiting for the clamping action of the rotating clamping assembly 300.

[0041] In this solution, the movement path of the material receiving seat 221 is designed to be inclined, that is, the material receiving seat 221 extends upward from the material receiving position to the material receiving position, the purpose of which is to ensure more stable transportation of pipe materials; through the inclined path design, it can be more effectively prevented that the pipe material clamped by the rotating clamping assembly 300 will interfere with the material receiving seat 221 during the retraction action.

[0042] Preferably, the receiving seat 221 is V-shaped and integrally formed. However, in this solution, the receiving seat 221 is L-shaped, and the L-shaped receiving seat 221 is adaptively installed and adjusted so that the final structure is similar to a V-shape, ensuring that the pipe material can stably fall into the receiving seat 221.

[0043] In this solution, the side of the receiving seat 221 that contacts the pipe material is the receiving surface, and the lowest point of the receiving surface is transitioned through an arc surface. By designing the arc surface, the receiving seat 221 can better match the shape of the pipe material, and the pipe material fits better on the receiving seat 221, thereby improving the stability during transportation.

[0044] Taking into account that the material receiving seat 221 has telescopic movement, if the stability of the pipe material is not restricted, the pipe material is very likely to roll out of the material receiving seat 221 under the action of driving force and inertia. Therefore, in order to avoid this situation, the material receiving seat 221 is improved in the present scheme, that is, a vacuum suction hole 223 is provided on the arc surface of the material receiving seat 221, and a suction head 224 connected to the negative pressure device is connected to the material receiving seat 221, and the vacuum suction hole 223 is connected to the suction head 224.

[0045] Under the action of the negative pressure equipment, a great negative pressure suction force will be generated at the vacuum suction hole 223. When the pipe material is in the material receiving seat 221, the negative pressure suction force sucks the pipe material, making the pipe material more stably fit with the material receiving seat 221. Such a structural design can greatly avoid the risk of the pipe material rolling out of the material receiving seat 221, and improve the stability of the transportation process.

[0046] The first power source 222 can be a power output device such as a linear motor, an electric cylinder, or a pneumatic cylinder; in this embodiment, a pneumatic cylinder is preferred; at the same time, it is ensured that the pipe material will fall only when the material receiving seat 221 is in the material receiving position; in this embodiment, a baffle 225 is designed on the pneumatic cylinder; specifically, the material receiving assembly 220 also includes a baffle 225, which is fixed to the material receiving seat 221 so as to be configured to be linked with the material receiving seat 221; when the material receiving seat 221 leaves the material receiving position, the baffle 225 blocks the pipe material from falling.

[0047] It can be understood that the baffle 225 is installed on the cylinder and moves with the material receiving seat 221. When the material receiving seat 221 is in the material receiving position, the baffle 225 is hidden below the low point; but as soon as the material receiving seat 221 receives the pipe material and leaves the material receiving position, the baffle 225 is pulled out synchronously, so that the pipe material at the low point cannot fall; until the material receiving seat 221 is in the material receiving position again, the baffle 225 is hidden again, and the pipe material falls normally into the material receiving position.

[0048] After the receiving seat 221 transfers the pipe material to the receiving position, the rotating clamping assembly 300 will start to move and clamp the pipe material on the receiving position. After the receiving seat 221 leaves the receiving position, the laser cutting assembly 400 will move again to achieve cutting processing of the short pipe material.

[0049] In this solution, the rotating clamping assembly 300 includes a hollow rotating motor 310 and an elastic spring-type ejector head 320; the spring-type ejector head 320 and the hollow rotating motor 310 jointly clamp the pipe material located in the receiving position and rotate the pipe material.

[0050] Specifically, the rotating clamping assembly 300 also includes a second driving source 330 , and the spring-type ejector head 320 is connected to the output end of the second driving source 330 ; the spring-type ejector head 320 is driven by the second driving source 330 to push the pipe material located in the receiving position into the hollow rotating motor 310 .

[0051] It can be understood that the spring-type ejector head 320 has a bullet-like ejector pin portion. Since the pipe material is a hollow structure, the bullet-shaped ejector pin structure can be efficiently and stably ejected into the pipe material. After the sensor detects that the pipe material is in the receiving position, the second driving source 330 will drive the spring-type ejector head 320 to extend and act on the hollow position at one end of the pipe material. The pipe material is pushed horizontally and linearly until the other end enters the hollow rotating motor 310. The hollow rotating motor 310 has a clamping claw to stably clamp the pipe material. At this time, the pipe material will be stably clamped under the dual action of the spring-type ejector head 320 and the hollow rotating motor 310.

[0052] In this solution, in order to prevent the spring-type ram 320 from coming into hard contact with the pipe material, the spring-type ram 320 is designed to be elastic, that is, the spring-type ram 320 is composed of a spring, so that the spring-type ram 320 has a certain elastic buffer when it is pressed against the pipe material, which can effectively avoid collision and damage to the pipe material.

[0053] At the same time, in this solution, the hollow rotating motor 310 has the function of rotating the pipe material. The hollow rotating motor 310 will be linked with the laser cutting assembly 400. The hollow rotating motor 310 clamps the pipe material and rotates it, so that the laser head 410 in the laser cutting assembly 400 can perform shaping cutting at a preset position.

[0054] Optionally, in order to improve the flexibility of the laser cutting assembly 400, the laser cutting assembly 400 of the present solution includes a laser head 410 and a driving module 420; the driving module 420 here is configured to drive the laser head 410 to move in the X-axis, Y-axis and Z-axis directions.

[0055] It can be understood that the driving module 420 can drive the laser head 410 to move in three axes, and perform shaping cutting on the pipe material according to a preset program and in cooperation with the hollow rotary motor 310 to meet different industrial needs.

[0056] This technical solution is a special equipment designed based on its own advantageous technology for processing short tube materials. The design refers to the design concepts of the early first and second generation laser equipment; however, this solution is also different from the first and second generation laser cutting equipment that are only suitable for long tube materials. In this solution, a material receiving component 220 is designed in the feeding mechanism 200, and the movement path of the material receiving seat 221 in the material receiving component 220 is inclined upward, which is more suitable for the characteristics of short tube materials, thereby realizing stable and efficient feeding of short tube materials.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
