Description

Technical Field

[0001] This utility model belongs to the field of laser cutting technology, specifically a tube support mechanism for a laser cutting machine. Background Technology

[0002] Laser cutting involves focusing a laser beam emitted from a laser source into a high-power-density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting or boiling point. Simultaneously, 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, a kerf is eventually formed in the material, thus achieving the purpose of cutting.

[0003] Existing tube support devices for laser cutting machines are indispensable, as they significantly impact the precision of tube cutting. However, existing support devices, while ensuring mobility, make it difficult to fine-tune the loaded tube, affecting cutting accuracy. Furthermore, they require a separate loading mechanism, increasing both the difficulty and cost of equipment use. The time lag between multiple components also increases processing time and reduces efficiency. Therefore, it is necessary to develop a tube support mechanism for laser cutting machines to address the shortcomings of existing technologies. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 5 As shown, this utility model provides a tube support mechanism for a laser cutting machine, including a support platform 1. Two symmetrical support plates 2 are arranged on the top of the support platform 1. The two support plates 2 are inclined. The extension line of the center line of the two support plates 2 is smaller than the bottom of the support plate 2. A plurality of evenly distributed support balls 3 are movably embedded in the top of the support plates 2. A feeding assembly 4 is arranged on the top of the support platform 1 between the two support plates 2. A pressing assembly 5 is arranged on the top of the feeding assembly 4 near the laser cutter between the two support plates 2.

[0024] The holding assembly 5 includes a holding frame 51 disposed between two support plates 2. Two parallel and symmetrical holding rollers 52 are movably mounted on the bottom of the holding frame 51. The axes of the holding rollers 52 are parallel to the feeding assembly 4. Due to the setting of the supporting balls 3, with the cooperation of the holding assembly 5, the tube can be driven to rotate radially, so that the end to be cut can rotate under the laser cutter, thereby completing the purpose of circumferential cutting. Moreover, after the feeding is completed, the supporting balls 3 also make it easy for the operator to manually move the tube a short distance to achieve fine adjustment and improve the cutting accuracy.

[0025] The outer surface of the supporting ball 3 is smooth, while the outer surface of the pressure roller 52 is rough. The pipe to be cut is clamped between the supporting ball 3 and the pressure roller 52.

[0026] The pressure holding frame 51 is provided with a linkage mechanism 55 on one side. The linkage mechanism 55 consists of a rotating transmission belt and two pulleys sleeved at both ends. A positioning roller 53 is fixedly connected to one side of the pulley and rotated inside the pressure holding frame 51. The positioning roller 53 is fixedly sleeved inside the pressure holding roller 52. Due to the setting of the linkage mechanism 55, the two positioning rollers 53 can rotate synchronously, thereby driving the two pressure holding rollers 52 to rotate synchronously. Thus, with the cooperation of several support balls 3 on the two support plates 2 below, they drive the pipe to rotate so as to cooperate with the laser cutter to complete the circumferential cutting.

[0027] A rotary motor 54 is fixedly installed on the other side of the pressure holder 51, and one end of the output shaft of the rotary motor 54 is fixedly connected to the end of one of the positioning rollers 53 away from the linkage mechanism 55.

[0028] The feeding assembly 4 includes a feeding rack 41 located above the support platform 1 and between two support plates 2. The bottom of the feeding rack 41 is provided with several first lifting rods 42. The bottom of the first lifting rods 42 is fixedly installed on the top of the support platform 1, and the top of the movable end of the first lifting rods 42 is fixedly connected to the bottom of the feeding rack 41. Due to the setting of the feeding assembly 4, with the cooperation of the support balls 3, fast and efficient feeding can be completed, thereby improving the cutting efficiency. At the same time, the supporting effect of the support balls 3 can also reduce the resistance when feeding the pipe, greatly reducing the energy consumption of feeding.

[0029] The feeding rack 41 has a feeding conveyor belt 43 movably installed inside. The feeding conveyor belt 43 has several evenly distributed transmission rollers 44 inside its transmission sleeve. Both ends of the transmission rollers 44 are rotatably sleeved inside the feeding rack 41. A feeding motor 45 is fixedly installed on the back of the feeding rack 41. The front end of the output shaft of the feeding motor 45 is fixedly connected to the rear end of one of the transmission rollers 44. Due to the setting of the feeding conveyor belt 43, with the cooperation of the several transmission rollers 44, the feeding conveyor belt 43 can be supported, so that the top of the feeding conveyor belt 43 can provide support for the pipe above, ensuring that it can form good friction with the pipe when it rises, and ensuring that the feeding conveyor belt 43 can push the pipe to complete the feeding.

[0030] The support plate 2 is fixedly connected to the bottom of the support frame 6, and the lower end of the support frame 6 is fixedly installed on the top of the support platform 1. The top of the support platform 1 is fixedly installed with a hoisting frame 7 located outside the two support plates 2. The top of the hoisting frame 7 is fixedly installed with a second lifting rod 8. The bottom of the movable end of the second lifting rod 8 is fixedly connected to the top of the pressure frame 51. The second lifting rod 8 and the feeding motor 45 are both connected to the same control system. The control system makes the operation of the second lifting rod 8 and the feeding motor 45 cooperate with each other, so that the two operate alternately. Specifically, when the second lifting rod 8 drives the pressure frame 51 to move upward, the first lifting rod 42 pushes the feeding frame 41 to rise. Conversely, when the second lifting rod 8 drives the pressure frame 51 to fall, the first lifting rod 42 drives the feeding frame 41 to fall.

[0031] Working principle and usage process of this utility model:

[0032] Place the equipment on the laser tube cutting table and ensure that one end of the support platform 1 above the holding component 5 is close to the laser cutting emitter. Then, feed the material through the other side, that is, place the tube to be cut between the two support plates 2, and it can be aligned and movably supported with the cooperation of the support balls 3.

[0033] Then, the hydraulic mechanism pushes the loading rack 41 upward through the first lifting rod 42 until the top of the loading conveyor belt 43 abuts against the bottom of the pipe. At this time, the loading motor 45 runs and drives the loading conveyor belt 43 through the transmission roller 44. With the cooperation of the support ball 3, the cutting point of the pipe is pushed axially to the bottom of the laser cutting emitter. Then, the hydraulic mechanism lowers the loading rack 41 and the loading conveyor belt 43 as a whole through the first lifting rod 42 and detaches from the pipe under the restriction of the support ball 3.

[0034] Then, under the constraint of the lifting frame 7, the hydraulic mechanism pushes the pressure holding frame 51 down through the second lifting rod 8, so that the two pressure holding rollers 52 can move down and abut against the front and rear sides of the top of the pipe. At this time, the rotary motor 54 runs, and with the cooperation of the support ball 3, the pipe can be rotated radially through the linkage mechanism 55 and the two pressure holding rollers 52, so that the laser cutter can complete the circumferential cutting of the pipe.
