[0031] 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.

[0032] Example 1

[0033] like Figures 1 to 2 As shown, the laser tube cutting machine with a feeding auxiliary mechanism proposed in this embodiment includes a frame 1, a first gantry frame 101 and a laser cutting head 102. The first gantry frame 101 is fixedly connected to the rear side of the top of the frame 1, and the laser cutting head 102 is connected to the rear side of the first gantry frame 101.

[0034] A rotary horizontal drive feeding auxiliary support mechanism is installed on frame 1. The rotary horizontal drive feeding auxiliary support mechanism includes:

[0035] V-shaped supports 2, which consist of two sets, with the rear V-shaped supports 2 fixedly connected to the top rear side of the frame 1. Two support balls 201 are movably embedded on the inner walls of both sides of the V-shaped supports 2. The two V-shaped supports 2 and four support balls 201 are provided for the pipe to be cut to be clamped and movably clamped. The V-shaped shape of the V-shaped supports 2 makes it convenient to clamp various pipes with diameters larger than the distance between the two support balls 201 on the left and right sides.

[0036] The transverse guide and transverse drive assembly is mounted on the top of the frame 1 and is fixedly connected to the bottom of the V-shaped support 2 on the front side;

[0037] The second gantry 4 is fixedly connected to the top of the transverse guide drive assembly;

[0038] The U-shaped plate 401 is set above the V-shaped support 2 on the front side, and rectangular guide sleeves 402 that are slidably sleeved on the outside of the second gantry frame 4 are fixedly connected to both sides of it.

[0039] The pressure-controlled lifting and clamping assembly is installed on the second gantry 4 and fixedly connected to the top left side of the U-shaped plate 401;

[0040] The rotary drive clamping assembly is installed on the spiral plate 401 and located above the V-shaped support 2 on the front side; the horizontal guide drive assembly is used to drive the second gantry 4 and the V-shaped support 2 on the front side to move back and forth; the pressure control lifting clamping assembly is used to drive the spiral plate 401 to move up and down, and to control and press the spiral plate 401 when it is driven to move down; the rotary drive clamping assembly is used to press and fix the pipe to be cut downward when the spiral plate 401 is controlled and pressed, and to drive the pipe to be cut to rotate during cutting to assist in the full-circle rotary cutting operation.

[0041] Furthermore, the laser cutting head 102 is fixedly connected to the rear side of the first gantry 101 by multiple screws.

[0042] Furthermore, such as Figure 1 and 2 As shown, the transverse guide drive assembly includes an electric slide rail module 302, two T-shaped guide rails 301, and a moving plate 3. The electric slide rail module 302 is embedded and fixed on the top of the frame 1. The two T-shaped guide rails 301 are respectively fixedly connected to the two sides of the top of the frame 1. The moving plate 3 is slidably installed on the two T-shaped guide rails 301. The moving plate 3 is fixedly installed on the top of the moving end of the electric slide rail module 302. The top of the moving plate 3 is fixedly connected to the V-shaped support 2 on the front side and the bottom of the second gantry 4.

[0043] In this embodiment, the top of the frame 1 is provided with an insert groove with an opening on the front side, and the electric slide rail module 302 is fixedly installed on the inner wall of the bottom of the insert groove; the bottom of the moving plate 3 is provided with two T-shaped slide grooves with openings on both the front and back sides, and the T-shaped slide grooves are slidably connected to the corresponding T-shaped guide rails 301, so as to guide the moving plate 3 to slide back and forth.

[0044] In this embodiment, the electric slide rail module 302, two T-shaped guide rails 301 and the moving plate 3 cooperate to drive the moving plate 3 to move back and forth, and the two T-shaped guide rails 301 guide the moving plate 3 to move back and forth. The moving plate 3 drives the second gantry 4 and the front V-shaped support 2 to move back and forth.

[0045] Furthermore, such as Figure 1 and 2As shown, the pressure-controlled lifting and clamping assembly includes a PLC controller 602, a second electric telescopic rod 6, and a pressure sensor 601. The PLC controller 602 and the second electric telescopic rod 6 are both fixedly installed on the top of the second gantry 4. The extended end of the second electric telescopic rod 6 is movably inserted into the second gantry 4. The pressure sensor 601 is fixedly connected between the extended end of the second electric telescopic rod 6 and the top left side of the U-shaped plate 401. The second electric telescopic rod 6 and the pressure sensor 601 are both electrically connected to the PLC controller 602.

[0046] In this implementation scheme, the PLC controller 602, the second electric telescopic rod 6, and the pressure sensor 601 work together. The PLC controller 602 pre-sets the pressure value for closing the second electric telescopic rod 6 according to the safe fixed pressure range of different pipes to be cut. The second electric telescopic rod 6 is started in the forward direction, causing it to drive the U-shaped plate 401 downwards via the pressure sensor 601. The U-shaped plate 401 drives two rectangular guide sleeves 402 to slide vertically on the second gantry 4. When the U-shaped plate 401 can no longer move downwards, the pressure sensor 601 detects the downward pushing and squeezing force applied by the second electric telescopic rod 6, converts it into a standard electrical signal, and transmits it to the PLC controller 602. The PLC controller 602 converts the received standard electrical signal into an actual pressure value through analog-to-digital conversion. When the preset pressure value is reached, the PLC controller 602 controls the second electric telescopic rod 6 to automatically close, achieving the effect of driving the U-shaped plate 401 downwards and automatically controlling and tightening it during downward movement.

[0047] Furthermore, such as Figure 1 and 2 As shown, the rotary drive clamping assembly includes a rotary wheel 501, an anti-slip rubber sleeve 502, and a brake motor 5. The rotary wheel 501 is rotatably mounted on the inner wall of the rear side of the rotary plate 401. The anti-slip rubber sleeve 502 is adhesively fitted on the outer side of the rotary wheel 501. The brake motor 5 is fixedly mounted on the front side of the rotary plate 401. The output shaft of the brake motor 5 is fixedly connected to the front side of the rotary wheel 501. The rotary wheel 501 is located above the V-shaped support 2 on the front side.

[0048] In this embodiment, a rotating shaft is fixedly connected to the rear side of the rotating wheel 501, and a first bearing is fixedly connected to the inner wall of the rear side of the spiral plate 401. The inner ring of the first bearing is fixedly fitted to the outer side of the rotating shaft. The first bearing and the rotating shaft serve to rotate the rotating wheel 501.

[0049] In this implementation scheme, the rotating wheel 501, the anti-slip rubber sleeve 502, and the brake motor 5 work together. When the forming plate 401 moves downward and is pressed under controlled pressure, the forming plate 401 drives the anti-slip rubber sleeve 502 to move downward and press the pipe to be cut under controlled pressure via the rotating wheel 501. During cutting, the brake motor 5 drives the rotating wheel 501 to rotate, which in turn drives the anti-slip rubber sleeve 502 to rotate. The friction of the anti-slip rubber sleeve 502 causes the pressed pipe to rotate, thus achieving the effect of driving the pipe to be cut to rotate during cutting to assist in the full-circle rotation cutting. After one cut, when the moving plate 3 is driven to move backward by the electric slide rail module 302, the moving plate 3 drives the V-shaped support 2 and the second gantry 4 on the front side to move backward. The second gantry 4 drives the pressed pipe to be cut to move backward in sequence through the rectangular guide sleeve 402, the U-shaped plate 401, the rotating wheel 501 and the anti-slip rubber sleeve 502. This achieves the effect of assisting the personnel to drive the pipe to be cut to move backward easily for feeding after one cut, so as to carry out the cutting work again. There is no need for the personnel to manually push the pipe to be cut with great effort, which improves the convenience and ease of use.

[0050] It should be noted that: the PLC controller 602 preferably adopts a Siemens S7-200SMART programmable controller with an integrated analog input module, which can receive the standard electrical signal output by the pressure sensor 601 and convert it into the actual pressure value through the integrated analog-to-digital conversion function; the pressure sensor 601 preferably adopts a Transcell BSS series plate (pressure type) load cell; the electric slide rail module 302 preferably adopts a Feichuang FCL250-FC7-1S linear guide slide module. This product adopts a linear motor direct drive and has the characteristics of large stroke and strong load-bearing capacity, and can bear 50-100KG.

[0051] In addition, the pressure sensor 601 is electrically connected to the PLC controller 602 via a flexible wire. The second electric telescopic rod 6 is electrically connected to the PLC controller 602 via a wire and a servo driver. The servo driver is preferably a Siemens V90 servo driver, which is a commonly used driver for controlling motors and electric actuators in conjunction with Siemens programmable controllers, meeting the requirements of the programmable controller to directly control the second electric telescopic rod 6. Since the pressure sensor 601 is a moving part, the flexible wire connecting it is conventionally designed with a certain bending length to meet its displacement requirements. This method of establishing an electrical connection controlled by the PLC controller 602 through a direct wire connection is a mature and well-known technology for conventional wired control of the controller, and will not be described in detail here.

[0052] Control switches are fixedly installed on the right side of the brake motor 5 and the front side of the electric slide rail module 302. The control switches are electrically connected to the corresponding components through wires. In terms of power supply, given that the laser tube cutting machine is used in a critical cutting and processing site with sufficient mains power supply facilities, all electrical components of this device are connected to the mains power supply. They are connected to the power input interface of each device through conventional power distribution devices such as circuit breakers, contactors, and power modules, as well as flexible wires (not marked in the figure), to form a complete power supply circuit. This power supply scheme is a conventional power distribution method for industrial equipment and is a mature and well-known technology, which will not be described in detail here.

[0053] This embodiment facilitates pressure-controlled, anti-slip clamping and fixing of the pipe to be cut. By using pressure-controlled fixing, the risk of deformation caused by excessive fixing force is reduced, improving safety. It also facilitates driving the pipe to be cut to rotate during laser cutting to assist in the full-circle rotation cutting operation. Furthermore, it facilitates automatic feeding of the pipe to be cut after one cut for recutting, eliminating the need for manual effort to push the heavy pipe to be cut, thus improving ease of use.

[0054] The usage method of this embodiment is as follows: When using the laser tube cutting machine with a feeding auxiliary mechanism, the tube to be cut is inserted between the four support balls 201 placed on the two V-shaped supports 2. The four support balls 201 are used to move and hold the tube to be cut. The V-shaped shape of the V-shaped supports 2 is convenient for holding various tubes with diameters larger than the distance between the two opposing support balls 201. The pressure value for closing the second electric telescopic rod 6 is preset using the PLC controller 602 according to the safety fixing pressure range of different tubes to be cut. The second electric telescopic rod 6 is started in the forward direction, causing it to drive the return plate 401 to move downward through the pressure sensor 601. The return plate 401 drives the two rectangular guide sleeves 402 to slide vertically on the second gantry 4. The rotating wheel 501 drives the anti-slip sleeve 502 to move down and press against the top of the pipe to be cut. At this time, the rotating wheel 501 is blocked by the pipe and no longer moves down, which in turn prevents the U-shaped plate 401 from moving down further. At this time, the pressure sensor 601 detects the pushing and squeezing force applied downward by the second electric telescopic rod 6 and converts it into a standard electrical signal, which is transmitted to the PLC controller 602. The PLC controller 602 converts the received standard electrical signal into an actual pressure value through analog-to-digital conversion. When the preset pressure value is reached, the PLC controller 602 controls the second electric telescopic rod 6 to close automatically. Combined with the anti-slip effect formed by the anti-slip sleeve 502, the anti-slip clamping and fixing effect of the pipe to be cut is achieved. The pressure-controlled fixing method reduces the risk of deformation caused by large fixing force and improves the safety of use.

[0055] When using the laser cutting head 102 to laser cut the pipe, the operator starts the brake motor 5 to drive the rotating wheel 501 to rotate. The rotating wheel 501 drives the anti-slip rubber sleeve 502 to rotate. The friction of the anti-slip rubber sleeve 502 causes the pressed pipe to rotate, thus driving the pipe to rotate during cutting to assist in the full-circle rotation cutting effect. After one cut, the operator starts the electric slide rail module 302 in the forward direction to drive the moving plate 3 to move backward. The moving plate 3 drives the V-shaped support 2 and the second gantry 4 on the front side to move backward. The second gantry 4 drives the anti-slip pressed pipe to move backward in sequence through the rectangular guide sleeve 402, the U-shaped plate 401, the rotating wheel 501 and the anti-slip rubber sleeve 502. This achieves the effect of automatically pushing and feeding the pipe after one cut for the operator to perform the cutting work again, without the need for the operator to manually push the heavy pipe to be cut, improving the convenience and ease of use.

[0056] Example 2

[0057] like Figures 3 to 5 As shown, this embodiment differs from Embodiment 1 in that: the laser cutting head 102 is vertically connected to the rear side of the first gantry 101, the laser cutting head 102 does not contact the rear side of the first gantry 101, and a first electric telescopic rod 103 is fixedly installed on the rear side of the first gantry 101, with the extended end of the first electric telescopic rod 103 fixedly connected to the top of the laser cutting head 102.

[0058] This embodiment allows for flexible adjustment of the height of the laser cutting head 102, making it easy to adapt to the cutting of various specifications of pipes and improving its applicability.

[0059] The method of use in this embodiment is as follows: The difference from the first embodiment is that, based on the first embodiment, it also has the following functions: the first electric telescopic rod 103 can drive the laser cutting head 102 to rise and fall, so as to achieve the effect of adjustable height of the laser cutting head 102. By using its height adjustable method, it is convenient to adapt to the cutting work of various specifications of pipes to be cut, and improves applicability.

[0060] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
