[0016] The movable slide mechanism of this utility model has a reasonable structural design and is easy to use.

[0018] The adaptive pipe stabilizer of this invention can conveniently and effectively stabilize the pipe during the grooving process. A drive device moves the movable support arm up and down, causing the clamping rollers at the lower ends of the left and right clamping arms to move closer or further apart. The distance between the clamping rollers at the lower ends of the left and right clamping arms can be adjusted to accommodate pipes of different diameters. When the distance between the clamping rollers at the lower ends of the left and right clamping arms matches the diameter of the pipe, the pipe is pressed down by these rollers. Since both rollers are rotatable, they do not affect the rotation of the pipe, thus stabilizing the pipe during grooving and improving processing stability.

[0019] The pipe conveying device of this utility model has a reasonable structural design and is easy to use. It drives the drive wheel to rotate through a power source, thereby conveying the pipe. When the pipe is conveyed to the end of the support frame, it is held in place by a pipe limiter. After inspection, if the pipe is qualified, the other end of the loading plate is raised by the loading plate power actuator. The other end of the loading plate is higher than the first end, and the qualified pipe on the loading plate rolls off the loading plate and enters the next grooving process. If the pipe is unqualified, the limiter power actuator drives the pipe limiter to rotate, so that the limit arm in the pipe limiter is horizontal. The pipe limiter no longer blocks the pipe, and the pipe continues to be conveyed forward and transported to the unqualified pipe stacking area. Attached Figure Description

[0049] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0050] Example.

[0051] See Figures 1 to 23 The pipe fitting grooving production unit in this embodiment includes a processing platform 2, a moving platform 3, an automatic grooving device 4, a pipe fitting transfer conveyor line 5, an adaptive pipe fitting stabilizer 6, a material unloading conveyor line 7, a pipe fitting conveying device 8, and a moving slide mechanism 9. The processing platform 2 is fixedly installed at the front end of the moving slide mechanism 9, and the moving platform 3 is slidably installed at the end of the moving slide mechanism 9. The material unloading conveyor line 7 and the pipe fitting conveying device 8 are respectively installed on both sides of the moving slide mechanism 9. The automatic grooving device 4 and the pipe fitting transfer conveyor line 5 are installed on both the processing platform 2 and the moving platform 3. The two automatic grooving devices 4 are respectively installed on the processing platform 2 and the moving platform 3 through their respective mounting bases 49. An adaptive pipe fitting stabilizer 6 is installed on each automatic grooving device 4.

[0052] The movable slide mechanism 9 in this embodiment includes a power drive device 91, a slider 92, a slide 93, a rack 94, a front limit sensor 95, a linear guide rail 96, an end limit sensor 97, a front limiter 98, a fixed platform 99, and a base 910.

[0053] In this embodiment, the top of the base 910 is fixed with a fixed platform 99 and two sets of parallel linear guide rails 96. Each set of linear guide rails 96 contains two linear guide rails. The fixed platform 99 is located at the front end of the base 910. The bottom of the slide table 93 is fixed with two sets of sliders 92, which are slidably connected to the two sets of linear guide rails 96, thereby slidably mounting the slide table 93 on the base 910. The slide table 93 and the fixed platform 99 are horizontally aligned. An end-position sensor 97 is fixed to the end of the base 910 and cooperates with the slide table 93. The end-position sensor 97 is located at the end of the slide table 93 to achieve dual detection of the slide table 93's position, ensuring safety during use.

[0054] In this embodiment, the rack 94 is fixed to the base 910, and the power drive device 91 is fixed to the bottom of the slide table 93. The power drive device 91 and the rack 94 cooperate to realize the movement of the slide table 93. The front limit sensor 95 is installed at the front of the slide table 93, and the front limit sensor 95 can determine the position of the slide table 93. The front limiter 98 is installed on the linear guide rail 96 and close to the fixed table 99, that is, the front limiter 98 is installed in the direction close to the fixed table 99. The power drive device 91 is installed on the slide table 93, and the slide table 93 is installed on the linear guide rail 96 through the slider 92. The rack 94 is fixed to the base 910, and the rack 94 and the linear guide rail 96 are parallel. The movement of the slide table 93 on the linear guide rail 96 is realized by the cooperation of the power drive device 91 and the rack 94. The processing platform 2 is installed on the fixed table 99, and the moving platform 3 is installed on the slide table 93.

[0055] In this embodiment, the power drive device 91 can be programmable, moving according to preset parameters. Based on the input pipe length and the actual pipe size deviation information fed back by the system, the power drive device 91 automatically adjusts the position of the slide table 93 on the linear guide rail 96 to automatically adapt to the pipe length processing requirements. Before operation, the sliding table mechanism 9 first controls the power drive device 91 to move the slide table 93 towards the fixed platform 99. When the front limit sensor 95 touches the front limit switch 98, this position is the reference point. After parameters are input to the power drive device 91, the slide table 93 automatically moves away from the fixed platform 99 and stops at the set position. Alternatively, the power drive device 91 in this embodiment can be non-programmable, controlled by a switch. The power drive device 91 contains gears that mesh with a rack 94 fixed to the base 910. Rotating the gears moves the power drive device 91 along the rack 94. The structure of the power drive device 91 is clear to those skilled in the art.

[0056] The automatic grooving device 4 in this embodiment includes a screw jack 41, a grooving mechanism body 42, a hydraulic cylinder 43, a coupling 44, a reducer 45, a sensor 46, a power source 47, a steering gear 48, a mounting base 49, and a grooving depth adjustment mechanism 410.

[0057] In this embodiment, the screw jack 41, power source 47, and steering gear 48 are all mounted on the mounting base 49. The power source 47 and steering gear 48 are connected, and the power in the power source 47 can be transmitted to the steering gear 48. The steering gear 48 is connected to the screw jack 41 through a coupling 44. Through the steering gear 48 and the coupling 44, the power from the power source 47 can be transmitted to the screw jack 41, realizing the lifting and lowering action of the screw jack 41.

[0058] In this embodiment, the grooving mechanism body 42 is mounted on the screw jack 41. When the screw jack 41 rises or falls under the action of the power source 47, the grooving mechanism body 42 will rise or fall synchronously to adapt to the outer diameter of the pipe to be processed. The reducer 45 is connected to the grooving mechanism body 42, and the sensor 46 is mounted on the side of the screw jack 41. The sensor 46 is used to detect the rising and falling origin of the screw jack 41.

[0059] In this embodiment, the hydraulic cylinder 43 is mounted on the grooving mechanism body 42, and the groove depth adjustment mechanism 410 is mounted on the hydraulic cylinder 43. The groove depth adjustment mechanism 410 rises or falls under the action of the hydraulic cylinder 43 to adapt to the wall thickness of the pipe to be processed. The groove depth adjustment mechanism 410 and the grooving mechanism body 42 cooperate to perform grooving processing on the pipe to be processed.

[0060] In this embodiment, the reducer 45 can be a programmable reducer, and the power source 47 can be a programmable power source. When the center height needs to be adjusted, after inputting the wall thickness and pipe diameter parameters of the pipe into the programmable reducer and the programmable power source, the PLC calculates the required center height of the grooving device. At this time, by controlling the movement of the power source 47, the coupling 44 and the steering gear 48 are driven to drive the screw jack 41 to drive the grooving mechanism body 42 to move upward or downward. When the grooving mechanism body 42 reaches the predetermined height setting position, the center height of the grooving device matches the wall thickness and pipe diameter parameters of the corresponding pipe fitting, and pipe fitting processing can begin. According to the input pipe fitting wall thickness and pipe diameter parameters, the groove depth adjustment mechanism 410 will also operate to the appropriate position under the action of the hydraulic cylinder 43. The groove depth adjustment mechanism 410 controls the grooving depth by controlling the downward pressing distance of the hydraulic cylinder 43. During the grooving process, the reducer 45 can also adjust the spindle output speed according to the corresponding pipe fitting parameters, making the grooving operation more stable. After processing is completed, the PLC controls the power source 47 to move, driving the grooving mechanism body 42 downwards via the screw jack 41. When it reaches the trigger position of the sensor 46, it returns to the origin to complete the process. Of course, the reducer 45 and power source 47 in this embodiment can also be of a non-programmable type; the control of the reducer 45 and power source 47 is clear to those skilled in the art.

[0061] The adaptive pipe stabilizer 6 in this embodiment includes a clamping roller 61, a left clamping arm 62, a movable support arm 63, a drive device 64, a right clamping arm 65, a support pin 66, and a housing 67. The left clamping arm 62 and the right clamping arm 65 are both arc-shaped structures.

[0062] In this embodiment, the housing 67 is a hollow structure. The housing 67 is provided with a set of left limiting grooves 68 and a set of right limiting grooves 69. Both the left limiting grooves 68 and right limiting grooves 69 on the housing 67 are arc-shaped structures, forming an inverted V-shape. The lower ends of the left clamping arm 62 and the right clamping arm 65 are both connected to clamping rollers 61. The clamping rollers 61 are rotatable, and the clamping rollers 61 located at the lower ends of the left clamping arm 62 and the right clamping arm 65 are flush.

[0063] In this embodiment, the upper end of the left clamping arm 62 is provided with a left limiting protrusion 611. The left clamping arm 62 is rotatably connected to the left part of the housing 67 via a support pin 66, and the connection point between the left clamping arm 62 and the housing 67 is near the upper end of the left clamping arm 62. The left clamping arm 62 can rotate around the connected support pin 66. The left limiting protrusion 611 on the left clamping arm 62 is located in the left limiting groove 68. When the left limiting protrusion 611 on the left clamping arm 62 moves along the left limiting groove 68, the left clamping arm 62 will rotate accordingly. The upper end of the right clamping arm 65 is provided with a right limiting protrusion 612. The right clamping arm 65 is rotatably connected to the right part of the housing 67 via a support pin 66, and the connection point between the right clamping arm 65 and the housing 67 is near the upper end of the right clamping arm 65. The right clamping arm 65 can rotate around the connected support pin 66. The right limiting protrusion 612 on the right clamping arm 65 is located in the right limiting groove 69. When the right limiting protrusion 612 on the right clamping arm 65 moves along the right limiting groove 69, the right clamping arm 65 will rotate accordingly.

[0064] In this embodiment, the movable support arm 63 is located inside the housing 67. Both the left and right ends of the movable support arm 63 are provided with horizontal grooves. The left limiting protrusion 611 in the left clamping arm 62 and the right limiting protrusion 612 in the right clamping arm 65 are respectively located in the grooves at the left and right ends of the movable support arm 63. That is, the groove at the left end of the movable support arm 63 rests on the left limiting protrusion 611 of the left clamping arm 62, and the groove at the right end of the movable support arm 63 rests on the right limiting protrusion 612 of the right clamping arm 65. On bar 612, when the movable support arm 63 moves up and down, the sliding groove at the left end of the movable support arm 63 pushes the left limiting protrusion 611 of the left clamping arm 62 to move along the left limiting groove 68, and the sliding groove at the right end of the movable support arm 63 pushes the right limiting protrusion 612 of the right clamping arm 65 to move along the right limiting groove 69, thereby realizing the rotation of the left clamping arm 62 and the right clamping arm 65, and achieving the purpose of adjusting the distance between the clamping rollers 61 at the lower end of the left clamping arm 62 and the lower end of the right clamping arm 65. The drive device 64 is mounted on the housing 67 and is connected to the movable support arm 63. The drive device 64 can control the up and down movement of the movable support arm 63.

[0065] Clamping rollers 61 are respectively installed in the left clamping arm 62 and the right clamping arm 65. The drive device 64 drives the movable support arm 63 to move up and down. The movable support arm 63 drives the left clamping arm 62 and the right clamping arm 65 to rotate, so that the two clamping rollers 61 are close to the pipe fitting 10 to be processed according to the pipe diameter, so that the pipe fitting 10 to be processed remains stable during the grooving process. Figure 3 and Figure 4It can be seen that by adjusting the distance between the clamping roller 61 at the lower end of the left clamping arm 62 and the clamping roller 61 at the lower end of the right clamping arm 65 through the drive device 64, it is possible to adapt to pipe fittings 10 with different diameters to be processed. It is convenient to use and can effectively stabilize the pipe fittings 10 to be processed during the grooving process.

The drive wheel 82 is thinner in the middle and thicker at both ends, and the diameter of the drive wheel 82 gradually increases from the middle to both ends.

[0067] In this embodiment, several drive wheels 82 are arranged in a row and rotatably mounted on the top of the support frame 89. The drive wheels 82 can rotate on the support frame 89. Adjacent drive wheels 82 are connected by a chain 810. The drive power source 812 is installed in the support frame 89 and is connected to the first drive wheel 82 via the chain 810. The drive power source 812 can drive the first drive wheel 82 to rotate. Since adjacent drive wheels 82 are connected by the chain 810, the drive power source 812 can ultimately drive all drive wheels 82 to rotate synchronously. Each drive wheel 82 has a sprocket 811 on its shaft. The chain 810 connecting adjacent drive wheels 82 is connected to the sprocket 811 of adjacent drive wheels 82, that is, the sprockets 811 on adjacent drive wheels 82 are connected by the chain 810.

[0068] In this embodiment, the top of the feeding plate 83 is provided with a triangular notch 813. One end of several feeding plates 83 is rotatably connected to the top of one side of the support frame 89. The other end of each feeding plate 83 is installed on the other side of the support frame 89 through a feeding plate power actuator 88. Under the action of the feeding plate power actuator 88, the other end of the feeding plate 83 can be lifted upward, so that the position of the other end of the feeding plate 83 is higher than the position of the first end of the feeding plate 83, thereby realizing the function of lifting the pipe 10 and rolling it out of the support frame 89. There are 2 to 4 drive wheels 82 between two adjacent feeding plates 83.

[0069] In this embodiment, the limiter actuator 87 is installed at the end of the support frame 89, and the pipe fitting limiter 86 is rotatably connected to the end of the support frame 89. The pipe fitting limiter 86 and the limiter actuator 87 are connected. The pipe fitting limiter 86 includes a limiting arm 814 and a transmission arm 815. One end of the limiting arm 814 and one end of the transmission arm 815 are connected. The included angle between the limiting arm 814 and the transmission arm 815 is between 100° and 150°. The connection between the limiting arm 814 and the transmission arm 815 is rotatably connected to the end of the support frame 89. The pipe fitting limiter 86 can rotate at the end of the support frame 89, thereby achieving the function of blocking the pipe fitting 10. The other end of the transmission arm 815 is connected to the limiter actuator 87. The photoelectric sensor 85 is installed at the end of the support frame 89, the position recognition sensor 81 is installed at the front end of the support frame 89, and the displacement sensor 84 is installed on the support frame 89. The displacement sensor 84 is located between the last two drive wheels 82.

[0070] In this embodiment, the position recognition sensor 81 is installed at the front end of the support frame 89 to detect the length of the pipe fitting 10; the displacement sensor 84 is installed between the last two drive wheels 82, and the displacement sensor 84 identifies the pipe diameter by judging the distance from the outer circle of the pipe fitting 10 to the displacement sensor 84; the photoelectric sensor 85 is located on the inner side of the end of the support frame 89 and is responsible for detecting the positioning signal of the pipe fitting 10; the pipe fitting limiter 86 is installed on the outer side of the end of the support frame 89; one end of the limiter power actuator 87 is installed on the support frame 89 and the other end is installed on the pipe fitting limiter 86; there are multiple feeding plate power actuators 88, one end of each feeding plate power actuator 88 is installed on the support frame 89 and the other end is installed on the feeding plate 83; the sprocket 811 is installed on the output shaft of the drive wheel 82; the chain 810 is installed on the sprocket 811, and the drive power source 812 is installed on the support frame 89, which drives the drive wheel 82 to transport the pipe fitting 10 through the chain 810 and the sprocket 811.

[0071] In this embodiment, when the pipe conveying device 8 is running, the first end of the pipe 10 to be conveyed is first conveyed onto the first drive wheel 82 on the left. The pipe 10 continues to advance until one end of the pipe 10 first contacts the position recognition sensor 81. At this time, the position recognition sensor 81 sends a signal, and the length of the pipe 10 is measured, and the drive power source 812 is started. The drive power source 812 drives the first sprocket 811 through the chain 810. The remaining sprockets 811 are also driven sequentially through the chain 810. The sprockets 811 drive all the drive wheels 82 to rotate together. At this time, the drive wheels 82 drive the pipe 10 to move to the right. One end of the pipe 10 first contacts the position recognition sensor 81, and the length of the pipe 10 is measured. The pipe 10 continues to move to the right until the tail end of the pipe 10 passes the position recognition sensor 81. At this time, the length measurement of the pipe 10 is completed. The pipe fitting 10 continues to move to the right until it is blocked by the raised pipe fitting limiter 86. At this time, the photoelectric sensor 85 detects the arrival signal of the pipe fitting 10, and the displacement sensor 84 begins to detect the outer diameter of the pipe fitting 10. The outer diameter and length of the pipe fitting 10 are used to determine whether the pipe fitting 10 is qualified. If the pipe fitting 10 is unqualified, the limiter actuator 87 will pull down, the pipe fitting limiter 86 will no longer block the pipe fitting 10, and the pipe fitting 10 will be transported to the unqualified pipe fitting stacking area. If the pipe fitting 10 is qualified, the loading plate actuator 88 pushes the loading plate 83 to lift, and the pipe fitting 10 will be poured into the next processing step.

[0072] In this embodiment, the pipe fitting conveying device 8 is responsible for receiving and inspecting the pipe fittings 10 to be processed; the moving platform 3 can move laterally as required under the action of the slide 93 of the moving slide mechanism 9, and the processing of pipe fittings 10 of different lengths can be controlled according to the distance between the two platforms, the slide 93 and the fixed platform 99; two height-adjustable automatic grooving devices 4 are respectively installed on the processing platform 2 and the moving platform 3, and their height adjustment function can adapt to pipe fittings 10 of different diameters and wall thicknesses; two pipe fitting transfer conveying lines 5 are respectively in front of the automatic grooving devices 4, responsible for the lateral pushing and transfer of pipe fittings 10; the adaptive pipe fitting stabilizer 6 is installed at the grooving position of the automatic grooving device 4, and is responsible for stabilizing the pipe fittings 10 during the grooving process; the unloading conveyor line 7 is responsible for conveying the processed pipe fittings 10 out of the production unit; the electrical control cabinet 1 is located in the right area of ​​the pipe fitting grooving production unit, and the electrical control cabinet 1 can be equipped with a PLC, a touch screen and other control components, responsible for the control functions of the entire pipe fitting grooving production unit.

[0073] In this embodiment, the pipe fitting grooving production unit processes pipe fitting 10 as follows: (e.g.) Figure 3As shown, the automatic grooving device 4 is raised to a suitable position to match the wall thickness and pipe diameter of the pipe fitting 10 to be processed. At the same time, the groove depth adjustment mechanism 410 of the automatic grooving device 4 will also move to a suitable position to limit the downward pressure position of the hydraulic cylinder 43, and control the grooving depth of the subsequent pipe fitting 10 grooving work. At this time, the preparation work is completed.

[0074] Processing begins by moving the finished pipe fitting 10 to the right side of the pipe fitting conveyor 8. The pipe fitting conveyor 8 transports the pipe fitting 10 and begins to check whether the outer diameter and length of the pipe fitting 10 meet the requirements according to the flow sequence. If it does not meet the requirements, the pipe fitting 10 will be pushed away directly from the left side of the pipe fitting conveyor 8. If it meets the requirements, the pipe fitting 10 will be poured into the pipe fitting transfer conveyor line 5 by the pipe fitting conveyor 8. At this time, the position of the moving platform 3 can be finely adjusted to accommodate the length deviation of the pipe fitting 10.

[0075] Pipe 10 begins to move along the pipe transfer conveyor line 5. When pipe 10 reaches the processing area of ​​the automatic grooving device 4 on the left, the pipe transfer conveyor line 5 pushes pipe 10 laterally onto the grooving component of the automatic grooving device 4. At this time, the adaptive pipe stabilizer 6 presses the pipe 10, and the grooving unit begins to work, starting the grooving process. It should be noted that the corresponding structure of the pipe transfer conveyor line 5, which moves pipe 10 and laterally pushes it onto the grooving component of the automatic grooving device 4, is clear to those skilled in the art.

[0076] After one end of the pipe fitting 10 is grooved, the pipe fitting transfer conveyor 5 pushes the pipe fitting 10 laterally back to the normal conveying position. The pipe fitting 10 continues to move with the pipe fitting transfer conveyor 5. When the pipe fitting 10 reaches the processing area of ​​the automatic grooving device 4 on the right, the pipe fitting transfer conveyor 5 pushes the pipe fitting 10 laterally onto the grooving component of the automatic grooving device 4 on the right, and begins the grooving work on the other end of the pipe fitting 10. It should be noted that the corresponding structure of the pipe fitting transfer conveyor 5 to achieve these functions—pushing the pipe fitting 10 laterally back to the normal conveying position, continuing to move the pipe fitting 10, and pushing the pipe fitting 10 laterally onto the grooving component of the automatic grooving device 4 on the right—is clear to those skilled in the art.

[0077] After the other end of the pipe fitting 10 is grooved, the pipe fitting transfer conveyor line 5 pushes the pipe fitting 10 laterally back to the normal conveying position. The pipe fitting 10 continues to run with the pipe fitting transfer conveyor line 5. When the pipe fitting 10 reaches the unloading position, the pipe fitting transfer conveyor line 5 sends the processed pipe fitting 10 into the unloading conveyor line 7, and the unloading conveyor line 7 sends the pipe fitting 10 out of the processing unit.

[0078] During continuous processing, multiple pipe fittings 10 are processed and transported simultaneously in the pipe fitting grooving production unit. The steps of pipe fitting inspection, processing of the first end of the pipe fitting, processing of the second end of the pipe fitting, and conveying the pipe fitting out of the production unit are carried out at the same time, resulting in high processing efficiency.
