Description

Technical Field

[0001] The utility model relates to the technical field of pipe fitting processing, and particularly relates to a combined cutting tool device for pipe fitting bevels. Background Technique

[0002] Pipe fittings are a general term for components in a pipeline system that play roles such as connection, control, direction change, flow division, sealing, and support. Welding connection is an important way of connecting pipe fittings. In order to ensure the quality of pipe fitting welding, it is necessary to pre-process the bevels at the ends of the pipe fittings. The bevels of pipe fittings are generally divided into X-shaped bevels, Y-shaped bevels, V-shaped bevels, U-shaped bevels, etc., and selective processing needs to be carried out according to differences in the size, material, and wall thickness of the pipe fittings.

[0003] However, the processing of different types of bevels requires different types of tools. Even in some processing cases, it is necessary to specifically change the inclination angle of the tool to process a bevel with a suitable inclination angle. The existing beveling machines can only install the same type of tool during processing, and manual tool changing is required when processing different types of pipe fittings. Manual tool changing has large errors and the tool changing process is cumbersome, which will seriously delay the processing time. The patent with the publication number CN214868717U discloses a tool connecting seat for a beveling machine that can continuously and precisely change the tool angle to eliminate the errors caused by tool changing. However, this tool changing process still needs to be manually adjusted, so the problems of large tool changing errors and cumbersome tool changing operations cannot be completely solved.

[0004] Therefore, we need a combined cutting tool device for pipe fitting bevels to solve the problems of large tool changing errors and cumbersome tool changing operations of the existing tool changing mechanism of beveling machines, which can effectively improve the tool changing accuracy and processing efficiency.

[0027] In order to clearly and completely describe the purpose and technical solutions of the present utility model and more clearly elaborate its advantages, the following further details the embodiments of the present utility model in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0028] Embodiment 1: Please refer to Figures 1 to 7 , the present utility model provides a combined cutting tool device for pipe fittings bevel, including a carrying device 3, an adjusting device 4, a controller 1 and a combined mounting device 6. The carrying device 3 includes a carrying plate 302 fixedly installed on the output end of the rotary motion of the beveling machine, and an adjustment fitting port 301 is provided on the carrying plate 302. A limit guiding groove 303 is provided on the side of the adjustment fitting port 301. The rotary motion output end of the beveling machine can drive the carrying plate 302 to rotate.

[0029] Please refer to Figures 1 to 5 , the adjusting device 4 includes a sliding plate 401 that slides left and right along the carrying plate 302, and a reversing motor 402 is fixedly installed on the sliding plate 401. A distance adjustment push rod 403 is fixedly installed on the carrying plate 302, and the output end of the distance adjustment push rod 403 is fixedly connected to the sliding plate 401 and drives the sliding plate 401 to slide.

[0030] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 6 , the combined mounting device 6 includes a central plate 607 fixedly installed on the output end of the reversing motor 402 and corresponding to the position of the adjustment fitting port 301. At least two support seats 605 clamped in the limit guiding groove 303 are arranged in a circumferential array on the central plate 607. A fixing frame 602 is fixedly arranged on the support seat 605, and a cutter head 7 is inserted and installed on the fixing frame 602. The cutter head 7 is pressed and fixed on the fixing frame 602 through a fixing screw 601.

[0031] In this embodiment, the rotating motion output end of the beveling machine can drive the bearing plate 302 to rotate. The distance adjustment push rod 403 can push the center plate 607 to a position concentric with the adjustment fitting port 301, or push the support seat 605 to a position where it is inserted into the limit guiding groove 303. The reversing motor 402 can be used to drive the center plate 607 to rotate, so as to rotate the corresponding cutter head 7 to a position corresponding to the limit guiding groove 303. The specific working process is as follows: First, install the corresponding type of cutter head 7 on each fixing frame 602. Then, use the distance adjustment push rod 403 to push the center plate 607 to a position concentric with the adjustment fitting port 301. Subsequently, use the reversing motor 402 to rotate the fixing frame 602 with the required type of cutter head 7 to a position corresponding to the limit guiding groove 303. Then, use the distance adjustment push rod 403 to push the fixing frame 602 to the working position where it is clamped by the limit guiding groove 303. Subsequently, drive the bearing plate 302 to rotate by using the rotating motion output end of the beveling machine, and then feed the pipe fitting into the processing area, and the corresponding cutter head 7 can be used to realize the processing of the bevel. Since the cutter heads 7 are all installed on the fixing frames 602 in advance, and the change of the direction and position of the cutter heads 7 can be accurately controlled by the reversing motor 402 and the distance adjustment push rod 403, the tool changing error is small, and the tool changing process is fast, which can effectively save time. It solves the problems of large tool changing error and cumbersome tool changing operation of the existing tool changing mechanism of the beveling machine, and can effectively improve the tool changing accuracy and processing efficiency.

[0032] Embodiment 2: Please refer to Figures 1 to 6, on the basis of the first embodiment, a mounting shaft 604 is fixedly installed on the fixing frame 602, and the fixing frame 602 is rotatably installed with the support seat 605 through the mounting shaft 604. A mating hole 606 is provided at the end of the mounting shaft 604, and the direction of the mating hole 606 is the same as the moving direction of the sliding plate 401. A rotating device 2 and a power device 5 are provided on the bearing plate 302. The rotating device 2 includes a central shaft 202 rotatably installed on the bearing plate 302, and a plug rod 201 fixedly installed on the central shaft 202 and inserted into the mating hole 606. A worm gear 203 is coaxially and fixedly installed on the central shaft 202. An angle adjustment motor 502 is fixedly installed on the bearing plate 302, and a worm 501 engaged with the worm gear 203 is driven at the output end of the angle adjustment motor 502. In this embodiment, the mounting shaft 604 is a damping rotating shaft, which can use the damping provided by the damping rotating shaft to prevent the spontaneous rotation of the mounting shaft 604. Therefore, it can ensure that the orientation of the mating hole 606 is always in the same direction as the moving direction of the sliding plate 401. In this way, when the fixing frame 602 is pushed by the distance adjustment push rod 403 and clamped into the limit guiding groove 303, the mating hole 606 can also be inserted and installed with the plug rod 201. Subsequently, the angle adjustment motor 502 drives the worm 501 to rotate, and the worm 501 can be used to drive the worm gear 203 to rotate. At the same time, the rotation of the worm gear 203 can also drive the mounting shaft 604 to rotate synchronously. In this way, it can be realized to adjust the inclination angle of the tool head 7 in real time by using the angle adjustment motor 502. Moreover, the worm gear mechanism composed of the worm gear 203 and the worm 501 also has a self-locking function, which can maintain the inclination angle of the tool head 7. When the tool head 7 needs to be replaced, only need to use the angle adjustment motor 502 to adjust the orientation of the mating hole 606 to the position in the same direction as the moving direction of the sliding plate 401 again. At this time, the sliding plate 401 can be pulled back to the position concentric with the adjustment mating port 301 through the distance adjustment device 4, and at the same time, the mating hole 606 and the plug rod 201 are correctly separated. Subsequently, the position of the tool head 7 can be adjusted by using the reversing motor 402. By changing the inclination angle of the tool head 7 through the angle adjustment motor 502, it is possible to effectively process grooves with different inclination angles using the same tool head 7, thereby reducing the number of tool changes and also reducing the number of tools required. Further solving the problems of large tool change error and cumbersome tool change operation of the existing tool change mechanism of the groove machine, it can effectively improve the tool change accuracy and improve the processing efficiency.

[0033] Embodiment Three: Please refer to Figure 3 and Figure 6, on the basis of the second embodiment, a torsion spring 603 for resetting the rotational position of the mounting shaft 604 is fixedly installed between the mounting shaft 604 and the support base 605, and a limiting block 608 for restricting the rotational position of the fixing frame 602 is fixedly installed on the support base 605. The torsion spring 603 can utilize its own elastic force to ensure that the fixing frame 602 is pressed against the limiting block 608, so that the orientation of the mating hole 606 can be the same as the movement direction of the sliding plate 401, ensuring that the mating hole 606 can be correctly inserted with the insertion rod 201. Further solves the problems of large tool changing error and cumbersome tool changing operation of the existing beveling machine tool changing mechanism, and can effectively improve the tool changing accuracy and processing efficiency.

The connecting seat 10 is fixedly installed with the rotational motion output end of the beveling machine, and a lead screw motor 8 is fixedly installed on the guide plate 9. A sliding seat 304 is fixedly installed at the rear end of the bearing plate 302, and the lead screw motor 8 drives the sliding seat 304 to move left and right along the guide plate 9 through a lead screw. A controller 1 is fixedly installed on the guide plate 9, and the controller 1 is electrically connected to the reversing motor 402, the distance adjustment push rod 403, the angle adjustment motor 502, and the lead screw motor 8 respectively. The reversing motor 402, the lead screw motor 8, and the angle adjustment motor 502 are all stepping motors, and the distance adjustment push rod 403 is a ball screw type electric push rod or a hydraulic push rod. In this embodiment, by fixing the connecting seat 10 with the rotational motion output end of the beveling machine and using the lead screw motor 8 to change the position of the bearing plate 302, the processing position can be automatically adjusted for pipes with different diameters, thereby improving the processing versatility of the equipment. Moreover, through programming the controller 1, automatic tool changing and beveling processing can be achieved, effectively improving the processing efficiency and the degree of intelligence of the equipment. Further solves the problems of large tool changing error and cumbersome tool changing operation of the existing beveling machine tool changing mechanism, and can effectively improve the tool changing accuracy and processing efficiency.

[0035] Embodiment 5: On the basis of the fourth embodiment, the present invention also provides a usage method of a pipe bevel combination cutting tool device, including the following steps:

[0036] Step 1: First, install the corresponding type of cutter head 7 on each fixing bracket 602.
