Description

Technical Field

[0001] This invention relates to the field of power pipe processing technology, and in particular to a power pipe grinding device. Background Technology

[0002] Electrical conduits are products made by hot-dip plastic coating of PE or internal and external coating of epoxy resin, possessing excellent corrosion resistance. The coating itself also has good electrical insulation properties, preventing electrolytic corrosion. They have low water absorption, high mechanical strength, and a low coefficient of friction, enabling long-term use. They also effectively prevent damage from plant roots and soil stress. After several processing steps, electrical conduits may have defects such as dents and scratches on their surface. Local repairs would result in unevenness on the inner and outer surfaces, thus requiring a grinding device to eliminate these defects.

[0003] Chinese Patent No. CN219747375U discloses a CPVC power pipe grinding device, which includes a working frame, a support frame, and a fixed frame. A screw is rotatably mounted inside the working frame. The bottom of the support frame is slidably connected to the working frame, and a stud is threaded inside the support frame. Sliding rods are slidably connected to the support frame at both ends of the stud. A support plate is rotatably mounted on the top of the stud, and the power pipe body is placed on top of the support plate. The bottom of the fixed frame is fixedly connected to the working frame, and the fixed frame is located on one side of the power pipe body. A grinding frame is rotatably mounted on the other side of the fixed frame. This utility model, through the combination of various structures, allows the device to ensure that the power pipe is placed in the middle position on the other side of the grinding mechanism via an adjustment mechanism and a measuring mechanism, thus facilitating subsequent grinding. It can simultaneously clamp and limit the inner and outer walls of the power pipe, ensuring uniform force on the power pipe and preventing deformation.

[0004] Regarding the aforementioned technologies, in the existing technology, workers use overtime and pressure plates to clamp the power pipe, and then use external and internal grinding blocks to grind the power pipe. However, the external and internal grinding blocks only grind the ends of the power pipe, and if there are defects such as dents or scratches on the surface of the power pipe, they cannot be repaired, which reduces the applicability of the power pipe grinding device. Summary of the Invention

[0005] To improve the applicability of power pipe grinding devices, this application provides a power pipe grinding device.

[0006] The power pipe grinding device provided in this application adopts the following technical solution:

[0007] A power pipe grinding device includes a frame, on which a stabilizing component for securing the power pipe and a rotating component for driving the power pipe to rotate are mounted. The frame also includes an axially movable seat and an axial drive component for driving the axially movable seat to move. The axially movable seat has two mounting frames and a first control component for driving the two mounting frames to move. Grinding strips are mounted on the mounting frames. The frame further includes an end grinding block and a radial drive component for driving the end grinding block to move.

[0008] By adopting the above technical solution, during grinding, the worker uses a stabilizing component to install the power pipe and a rotating component to drive the power pipe to rotate. Then, the axial drive component drives the axial moving seat to move, which in turn moves the two mounting frames and the grinding strips until the side wall of the power pipe is between the two grinding strips. Then, the first control component simultaneously drives the two mounting frames to move toward the side wall of the power pipe until the grinding strips abut against the power pipe. After grinding the inner and outer ring walls of the power pipe, the mounting frames are moved out of the power pipe range, and the radial drive component drives the end grinding block to move until the end grinding block abuts against the end of the power pipe, thus achieving the effect of grinding the end, inner ring wall and outer ring wall of the power pipe. By using the combination of grinding strips and axial drive components with end grinding blocks and radial drive components, workers can grind the ends, inner ring walls, and outer ring walls of power pipes. This process minimizes defects such as dents and scratches on the inner and outer ring walls, making them smoother and further improving the installation accuracy of the power pipes. Compared with existing technologies, this method enhances the applicability of the power pipe grinding device.

[0009] Optionally, the mounting frame has a grinding groove and a polishing groove, the grinding strip is slidably fitted in the grinding groove, the polishing strip is slidably fitted in the polishing groove, and the mounting frame is provided with a pushing component for driving the grinding strip and the polishing strip to move.

[0010] By adopting the above technical solution, during the polishing process, the workers first use the pushing component to move the polishing strip to eliminate defects on the inner and outer ring walls of the power pipe, and then move the polishing strip to polish the inner and outer ring walls of the power pipe, thereby further improving the surface roughness of the inner and outer ring walls of the power pipe and enhancing the aesthetics of the power pipe.

[0011] Optionally, the pushing assembly includes a pushing rod, a connecting rod, and a pushing cylinder. Several pushing rods are connected to both the grinding strip and the polishing strip. The pushing rods pass through the mounting frame. The pushing cylinder is mounted on the mounting frame. A moving rod is connected to the output end of the pushing cylinder. A pushing groove is formed on the pushing rod. The moving rod passes through the pushing groove. A fixing block is connected to the mounting frame at a position corresponding to two of the pushing rods. The connecting rod is rotatably connected to the fixing block. One end of the connecting rod slides into one of the pushing grooves and is rotatably connected to the moving rod.

[0012] By adopting the above technical solution, during the polishing process, the operator activates the push cylinder to move the moving rod, thereby pushing the polishing strip. After the power pipe is polished, the moving rod is retracted, causing the polishing strip to move in the opposite direction. Through the connecting rod, the polishing strip is moved, thus achieving the effect of polishing the surface of the power pipe after polishing.

[0013] Optionally, the first control component includes a rotating disk, a first control motor, and a control lever. The rotating disk is rotatably connected to the axial moving seat. A control arc groove is formed on the rotating disk at a position corresponding to the mounting frame. A radial groove is formed on the axial moving seat at a position corresponding to the control arc groove. The control lever is connected to one end of the mounting frame and passes through the radial groove and the control arc groove in sequence. A baffle is connected to the end of the control lever. A limiting member is provided on the axial moving seat to limit the angle of the mounting frame. The first control motor is mounted on the axial moving seat and coaxially connected to the rotating disk.

[0014] By adopting the above technical solution, when the installation frame is moved, the operator starts the first control motor to make the rotating disk rotate. Through the cooperation of the control arc groove and the radial groove, the two operating rods move towards the center of the rotating disk at the same time, driving the installation frame to move. This achieves the effect of the grinding strip grinding the inner and outer ring walls of the power pipe at the same time.

[0015] Optionally, the limiting member is a T-shaped rail, which is connected to the side wall of the axial moving seat near the mounting frame. The limiting member is parallel to the radial groove, and the mounting frame slides with the limiting member.

[0016] By adopting the above technical solution, the limiting component is used to assist the movement of the mounting frame, further improving the stability of the mounting frame during movement and ensuring that the mounting frame remains in the same state during movement.

[0017] Optionally, the axial drive assembly includes an axial drive motor, a drive gear, and a fixed rack. The axial drive motor is mounted on the axial moving seat, the drive gear is mounted on the output shaft of the axial drive motor, and the fixed rack is fixedly connected to the frame and parallel to the moving direction of the axial moving seat. The drive gear meshes with the fixed rack.

[0018] By adopting the above technical solution, when the axial moving seat is driven to move, the operator starts the axial drive motor to make the drive gear rotate. Through the meshing of the drive gear with the fixed rack, the axial moving seat is moved.

[0019] Optionally, a control frame is provided on the frame, and the control frame is connected to the moving end of the radial drive assembly. A second control assembly is provided on the control frame. The second control assembly includes a second control motor, a control screw, a control block, and a limiting rail. The control screw is rotatably connected to the control frame and is a bidirectional screw. The limiting rail is connected to the control frame and is parallel to the control screw. The second control motor is mounted on the control frame and coaxially connected to the control screw. Two control blocks are slidably engaged on the limiting rail. The control screw is threadedly engaged with the control blocks. An end grinding block is connected to the control block. During grinding, the end grinding block grinds the end of the power tube.

[0020] By adopting the above technical solution, when grinding the end of the power pipe, the operator uses the radial drive component to drive the control frame to move until the power pipe is between the two end grinding blocks. Then, the second control motor is started to rotate the control screw, which drives the two control blocks to move towards the middle position of the control screw at the same time, so that the end grinding blocks move until the end grinding blocks abut against the end of the power pipe, thus achieving the effect of grinding the end of the power pipe.

[0021] Optionally, the radial drive assembly includes a radial drive motor, a radial lead screw, a radial rod, and a radial moving block. The radial lead screw is rotatably connected to the frame, and the radial rod is connected to the frame and parallel to the radial lead screw. The radial drive motor is mounted on the frame and coaxially connected to the radial lead screw. The radial moving block is disposed between the radial lead screw and the radial rod, and the radial moving block is threadedly engaged with the radial lead screw and slidably engaged with the radial rod.

[0022] By adopting the above technical solution, when the control frame moves, the operator starts the radial drive motor, which rotates the radial lead screw and moves the radial moving block, thus achieving the effect of driving the control frame to move.

[0023] Optionally, the stabilizing component includes a support wheel, a pressure wheel, and a pressure cylinder. The frame is provided with several support frames, two of the support wheels are mounted on the support frames, the frame is provided with a mounting frame, the pressure cylinder is mounted on the mounting frame, and the pressure wheel is mounted on the output end of the pressure cylinder. When fixing the power pipe, the power pipe is located between the pressure wheel and the two support wheels.

[0024] By adopting the above technical solution, when installing the power pipe, the workers place the power pipe on two rows of support wheels, and then activate the pressure cylinder to lower the pressure wheels until they touch the top of the power pipe. This three-point restriction of the power pipe's degree of freedom enables the installation of the power pipe.

[0025] Optionally, the mounting bracket is vertically slidably fitted with a lifting seat, the lifting seat is connected between the pressure cylinder and the pressure wheel, the rotating component is a rotary motor, the pressure wheel is an I-beam wheel, and the rotating component and the pressure wheel are connected by a synchronous belt.

[0026] By adopting the above technical solution, when the power pipe is driven to rotate, the staff starts the rotating component, and through the synchronous belt, the pressure wheel rotates, and the rotation of the power pipe is achieved through friction.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. During grinding, the worker uses a stabilizing component to install the power pipe and a rotating component to drive the power pipe to rotate. Then, the axial drive component drives the axial moving seat to move, which in turn moves the two mounting frames and the grinding strips until the side wall of the power pipe is between the two grinding strips. Then, the first control component simultaneously drives the two mounting frames to move toward the side wall of the power pipe until the grinding strips touch the power pipe. After grinding the inner and outer ring walls of the power pipe, the mounting frames are moved out of the power pipe area, and the radial drive component drives the end grinding block to move until the end grinding block touches the end of the power pipe, thus achieving the effect of grinding the end, inner ring wall and outer ring wall of the power pipe. By using the combination of grinding strips and axial drive components with end grinding blocks and radial drive components, workers can grind the ends, inner ring walls, and outer ring walls of power pipes. This process minimizes defects such as dents and scratches on the inner and outer ring walls, making them smoother and further improving the installation accuracy of the power pipes. Compared with existing technologies, this method enhances the applicability of the power pipe grinding device.

[0029] 2. During polishing, the operator activates the cylinder to move the moving rod, which in turn moves the polishing strip. After the power pipe is polished, the moving rod is retracted, causing the polishing strip to move in the opposite direction. Through the connecting rod, the polishing strip is moved, thus achieving the effect of polishing the surface of the power pipe after polishing.

[0030] 3. When the installation frame is moved, the operator starts the first control motor to make the rotating disk rotate. Through the cooperation of the control arc groove and the radial groove, the two operating rods move towards the center of the rotating disk at the same time, driving the installation frame to move. This achieves the effect of the grinding strip grinding the inner and outer ring walls of the power pipe at the same time. Attached Figure Description

[0039] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0040] This application discloses a grinding device for power pipes. (Refer to...) Figure 1 The power pipe grinding device includes a frame 1, on which a stabilizing component 2 for securing the power pipe and a rotating component 3 for driving the power pipe to rotate are mounted. An axial moving seat 11 and an axial drive component 4 for driving the axial moving seat 11 are mounted on the frame 1. Two mounting frames 111 and a first control component 5 for driving the two mounting frames 111 to move are mounted on the axial moving seat 11. Grinding strips 112 are mounted on the mounting frames 111. An end grinding block 12 and a radial drive component 6 for driving the end grinding block 12 to move are also mounted on the frame 1.

[0041] Workers use the stabilizing component 2 to install the power pipe, then use the rotating component 3 to drive the power pipe to rotate, and then use the axial drive component 4 to drive the axial moving seat 11 to move, which in turn drives the two mounting frames 111 to move until the side wall of the power pipe is between the two grinding strips 112. Then, the first control component 5 is used to drive the grinding strips 112 to move until they contact the power pipe. After grinding the power pipe, the mounting frame 111 is removed from the power pipe area, and the radial drive component 6 is used to move the end grinding block 12 until the end grinding block 12 contacts the end of the power pipe, thus achieving the effect of grinding the inner ring wall, outer ring wall and end of the power pipe.

[0042] Reference Figure 2 The stabilizing component 2 includes a support wheel 21, a pressure wheel 22, and a pressure cylinder 23. Several support frames are fixedly connected to the frame 1; in this embodiment, two are used as an example.

The rotating component 3 is a rotating cylinder, connected to the pressure wheel 22 via a synchronous belt.

[0044] When driving the power pipe to rotate, the worker places the power pipe between the two support wheels 21, then activates the pressure cylinder 23 to lower the lifting seat 231, which in turn lowers the pressure wheel 22 until the pressure wheel 22 contacts the power pipe. Then, the rotating component 3 is activated, which drives the pressure wheel 22 to rotate via the synchronous belt. Through friction, the power pipe is rotated.

[0045] Reference Figure 3The axial drive assembly 4 includes an axial drive motor 41, a drive gear 42, and a fixed rack 43. An axial moving seat 11 is slidably fitted onto the frame 1. The axial drive motor 41 is mounted on the axial moving seat 11, and the drive gear 42 is mounted on the output shaft of the axial drive motor 41. The fixed rack 43 is fixedly connected to the frame 1 and is parallel to the direction of movement of the axial moving seat 11. The drive gear 42 meshes with the fixed rack 43.

[0046] Reference Figure 3 and Figure 4 The first control component 5 includes a rotating disk 51, a first control motor 52, and a control lever 53. The rotating disk 51 is rotatably connected to the axial moving seat 11. The rotating disk 51 has two control arc grooves 511, which are rotationally symmetrical about the axis of the rotating disk 51. The axial moving seat 11 has radial grooves 114 corresponding to the control arc grooves 511. One end of the control lever 53 is fixedly connected to the mounting frame 111, and the other end of the control lever 53 passes sequentially through the radial groove 114 and the control arc groove 511. A baffle is fixedly connected to the other end of the control lever 53. The first control motor 52 is mounted on the axial moving seat 11 and coaxially connected to the rotating disk 51.

[0047] Reference Figure 4 and Figure 5 A limiting member 115 is provided on the axial moving seat 11 at the position corresponding to the mounting frame 111. The limiting member 115 is a T-shaped rail and is fixedly connected to the axial moving seat 11. The limiting member 115 is parallel to the radial groove 114, and the mounting frame 111 and the limiting member 115 are in sliding fit.

Grinding strip 112 is slidably fitted in the grinding groove, and polishing strip 113 is slidably fitted in the polishing groove. A pushing assembly 7 is provided on the mounting frame 111, which includes a pushing rod 71, a connecting rod 72, and a pushing cylinder 73. Several pushing rods 71 ​​are fixedly connected to both the grinding strip 112 and the polishing strip 113. One end of the pushing rod 71 passes through the mounting frame 111, and one end of the pushing rod 71 has a pushing groove. A fixing block is fixedly connected to the mounting frame 111 at a position corresponding to two pushing rods 71. The connecting rod 72 is hinged to the fixing block and slidably fitted between two pushing grooves. The pushing cylinder 73 is mounted on the mounting frame 111, and a moving rod 731 is hinged to the output end of the pushing cylinder 73. The moving rod 731 is hinged to one end of the connecting rod 72.

[0049] During polishing, the operator starts the axial drive motor 41, causing the drive gear 42 to rotate, which in turn moves the axial moving seat 11 and the mounting frame 111 until the power tube is positioned between the two mounting frames 111. Then, the operator starts the first control motor 52, causing the rotating disk 51 to rotate, which in turn moves the two control levers 53 towards the center of the rotating disk 51, moving the mounting frame 111 until it reaches the appropriate position. Then, the operator starts the push cylinder 73, which moves the push rod 71, causing the polishing strip 112 to move until it contacts the power tube. After the power tube is polished, the operator starts the push cylinder 73 in the opposite direction, causing the polishing strip 112 to move in the opposite direction. Through the connecting rod 72, the operator moves the polishing strip 113 until it contacts the power tube to polish it. Finally, the operator uses the axial drive motor 41 to move the axial moving seat 11 in the opposite direction until the mounting frame 111 is disengaged from the power tube, thus achieving the effect of polishing and grinding the surface of the power tube.

[0050] Reference Figure 3 and Figure 7 The radial drive assembly 6 includes a radial drive motor 61, a radial lead screw 62, a radial rod 63, and a radial moving block 64. The radial lead screw 62 is rotatably connected to the frame 1 and is perpendicular to the moving direction of the axial moving seat 11. The radial rod 63 is fixedly connected to the frame 1 and is parallel to the radial lead screw 62. The radial moving block 64 is slidably fitted onto the radial rod 63 and threadedly fitted onto the radial lead screw 62. The radial drive motor 61 is mounted on the frame 1 and coaxially connected to the radial lead screw 62.

[0051] Reference Figure 1 and Figure 7 A control frame 13 is bolted to the radial moving block 64. A second control assembly 8 is mounted on the control frame 13, comprising a second control motor 81, a control screw 82, a control block 83, and a limiting rail 84. The control screw 82 is rotatably connected to the control frame 13 and is parallel to the moving direction of the axial moving seat 11. The limiting rail 84 is fixedly connected to the control frame 13 and is parallel to the control screw 82. Two control blocks 83 slide on the limiting rail 84, and the control screw 82 passes through and is threaded into the control blocks 83. An end grinding block 12 is fixedly connected to the control block 83 and has a chamfered portion 121 for removing protruding burrs from the end of the power conduit.

[0052] When polishing the end of the power pipe, the operator starts the radial drive motor 61, which rotates the radial lead screw 62, causing the radial moving block 64 to move and drive the control frame 13 to move until the power pipe is between the two end polishing blocks 12. Then, the second control motor 81 is started, which rotates the control screw 82, causing the two control blocks 83 to move towards the middle position of the control screw 82 at the same time, driving the end polishing blocks 12 to move until the end polishing blocks 12 abut against the end of the power pipe, and the chamfered part 121 chamfers the end of the power pipe, thus achieving the effect of polishing the end of the power pipe.

[0053] The implementation principle of the power pipe grinding device in this embodiment is as follows: During grinding, the power pipe is placed between two support wheels 21. Then, the pressure cylinder 23 is activated to lower the lifting seat 231 until the pressure wheel 22 touches the power pipe. Then, the rotating component 3 is activated, and the pressure wheel 22 is rotated through the synchronous belt. Through friction, the power pipe is rotated. Then, the axial drive motor 41 is activated to rotate the drive gear 42, which moves the axial moving seat 11 until the power pipe is located between two mounting frames 111. Then, the first control motor 52 is activated to rotate the rotating disk 51, which moves the two control levers 53 simultaneously toward the center position of the rotating disk 51. After the mounting frame 111 is moved to the appropriate position, the push cylinder 73 is activated to move the push rod 71, which moves the grinding strip 112 until the grinding strip 112 touches the power pipe. After grinding, the reverse-starting cylinder 73 is activated to move the grinding strip 112 in the reverse direction. Through the connecting rod 72, the polishing strip 113 is moved until it contacts the power tube to polish it. Finally, the axial drive motor 41 is used to move the axial moving seat 11 in the reverse direction until the mounting frame 111 is disengaged from the power tube. Then, the radial drive motor 61 is activated to rotate the radial screw 62, which moves the radial moving block 64 and drives the control frame 13 to move until the power tube is located between the two end grinding blocks 12. Then, the second control motor 81 is activated to rotate the control screw 82, which moves the two control blocks 83 towards the middle position of the control screw 82, driving the end grinding blocks 12 to move until they contact the end of the power tube. The chamfered part 121 also grinds the end of the power tube, thus achieving the grinding of the inner ring wall, outer ring wall and end of the power tube.

[0054] By cooperating with the grinding strip 112 and the axial drive assembly 4, and with the end grinding block 12 and the radial drive assembly 6, the workers achieved grinding of the ends, inner ring wall, and outer ring wall of the power pipe. This eliminated defects such as dents and scratches on the inner and outer ring walls of the power pipe as much as possible, making the inner and outer ring walls of the power pipe smoother and further improving the installation accuracy of the power pipe. Compared with the existing technology, this improved the applicability of the power pipe grinding device.

[0055] The grinding device of this application is not limited to grinding power pipes, but can also be used for grinding the surface of other tubular parts.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
