[0036] The plastic pipe fittings that need to be polished and burred are placed on the fixed clamping plate 21 and the support plate 26. The support plate 26 can support the plastic pipe fittings to prevent the plastic pipe fittings from tilting, ensuring that the plastic pipe fittings remain in a horizontal state for polishing and burr removal. The U-shaped slide plate 25 can be moved left and right to adjust the position of the support plate 26 to the left and right to accommodate plastic pipe fittings of different lengths. The hydraulic cylinder 23 is controlled to drive the movable clamp 24 to move downward. After the movable clamp 24 moves downward, the plastic pipe fitting can be clamped and fixed on the fixed clamp 21 to avoid displacement of the plastic pipe fitting during subsequent grinding operations. Then, the adjusting screw Ⅰ6 is rotated to adjust the position of the lifting plate 7 in the up and down directions, and the telescopic plate 3 is extended and retracted accordingly, so that the electric rotating disk 4 and the components thereon can be adjusted in the up and down directions, so that the center of the circle of the electric rotating disk 4 is aligned with the center of the circle on the plastic pipe fitting, ensuring that the subsequent grinding rod Ⅰ93 and the grinding rod Ⅱ95 can always fit with the plastic pipe fitting to achieve grinding of the plastic pipe fitting when rotating with the electric rotating disk 4 to adapt to plastic pipe fittings of different diameters. Next, the control driving member 8 drives the telescopic plate 3 to drive the electric rotating disk 4 to move to the left, so that the grinding rod I93 moves to the left into the plastic pipe fitting, and the grinding rod II95 moves to the left to the bottom of the plastic pipe fitting, and then the adjusting screw III97 is rotated to adjust the position of the slotted mounting plate 92 in the upper and lower directions, so that the grinding rod I93 can be adjusted in the upper and lower directions, so that the grinding rod I93 fits the inner surface of the plastic pipe fitting, and then the adjusting screw II96 is rotated to adjust the position of the sliding block 94 in the upper and lower directions, so that the grinding rod II95 can be adjusted in the upper and lower directions, so that the grinding rod II95 fits the outer surface of the plastic pipe fitting.

[0037] Controlling the electric rotating disk 4 to rotate can drive the grinding rod I93 and the grinding rod II95 to rotate along the circumferential direction of the plastic pipe fitting, and controlling the driving motor 98 to work can drive the grinding rod I93 to rotate. The rotation of the grinding rod I93 drives the spline shaft I99 to rotate through the bevel gear set II912. The rotation of the spline shaft I99 drives the spline sleeve I910 to rotate. The rotation of the spline sleeve I910 drives the grinding rod II95 to rotate through the bevel gear set I911. The grinding rod I93 rotates and rotates along the circumferential direction of the plastic pipe fitting, and can grind and remove burrs on the inner surface of the plastic pipe fitting and the edge of the inner surface of the port. The grinding rod II95 rotates and rotates along the circumferential direction of the plastic pipe fitting, and can grind and remove burrs on the outer surface of the plastic pipe fitting and the edge of the outer surface of the port. After completing the grinding and burr removal work at one end, first control the driving member 8 to drive the telescopic plate 3 to drive the electric rotating disk 4 to move right and reset, so that the grinding rod I 93 and the grinding rod II 95 move right and reset to disengage from the plastic pipe fitting, then control the hydraulic cylinder 23 to drive the movable clamping plate 24 to move up and release the plastic pipe fitting, and then manually rotate the plastic pipe fitting to rotate the ungrinded end to the right, and then repeat the above operation to complete the grinding and burr removal of the two ends of the plastic pipe fitting.

[0038] See also Figure 3-Figure 4 The right side of the grinding rod Ⅰ93 is rotatably sleeved with a grinding disc 10 for grinding the end surface of the plastic pipe fitting. The grinding disc 10 is fixedly connected to the slotted mounting plate 92. The grinding disc 10 is located on the left side of the bevel gear set Ⅱ912. The grinding disc 10 is provided with a receiving groove 11 for accommodating the grinding rod Ⅱ95.

[0039] The slotted mounting plate 92 moves to the left, driving the grinding disc 10 to move to the left and to be in close contact with the end face of the plastic pipe fitting. The slotted mounting plate 92 rotates, driving the grinding disc 10 to rotate, grinding and removing burrs on the end face of the plastic pipe fitting, thereby being able to grind the end face of the plastic pipe fitting to be smoother, improving the grinding effect, and thereby improving product quality.

[0040] See also Figure 5-Figure 7An auxiliary centering mechanism is provided between the fixed splint 21, the movable splint 24 and the telescopic plate 3, and the auxiliary centering mechanism is used to assist the center of the electric rotating disk 4 to align with the center of the plastic pipe fitting. The auxiliary centering mechanism includes a connecting plate Ⅰ121 hinged to the rear side of the right side of the movable splint 24, and the lower part of the connecting plate Ⅰ121 is connected to a connecting rod 123, and a connecting plate Ⅱ122 is hinged on the connecting rod 123. The connecting plate Ⅱ122 is hinged to the rear side of the right side of the fixed splint 21, and a rotating shaft 125 is rotatably connected to the rear side of the telescopic end of the telescopic plate 3, and the central axis of the rotating shaft 125 The wire is at the same height as the central axis of the rotating disk on the electric rotating disk 4, a volute spring 126 is connected between the rotating shaft 125 and the telescopic end of the telescopic plate 3, a pull box 127 is rotatably sleeved on the rear side of the rotating shaft 125, the pull box 127 is fixedly connected to the telescopic end of the telescopic plate 3 through a connecting rod, a wire groove is opened on the left side of the side wall of the pull box 127, the wire groove and the center of the rotating disk on the electric rotating disk 4 are at the same height, a pull rope 124 is connected to the right side of the connecting rod 123, the pull rope 124 passes through the wire groove on the pull box 127 and is wrapped around the rotating shaft 125.

[0041] Initially, the volute spring 126 is in a compressed state. Since the connecting plate Ⅰ121 is hinged to the connecting plate Ⅱ122 through the connecting rod 123, when the movable clamp 24 moves down to clamp the plastic pipe fitting, the connecting plate Ⅰ121 drives the connecting rod 123 to move to the lower right until it is at the same height as the central axis of the plastic pipe fitting. The left end of the pull rope 124 is then parallel to the central axis of the plastic pipe fitting and is at the same height as the central axis of the plastic pipe fitting. The connecting rod 123 moves to the lower right to relax the pull rope 124. Under the resetting action of the volute spring 126, the rotating shaft 125 rotates to rewind the pull rope 124 to ensure that the pull rope 124 always remains taut. Then, the adjusting screw rod Ⅰ6 is rotated to adjust the position of the lifting plate 7 in the up and down direction, and the telescopic plate 3 is telescoped accordingly, so that the electric rotating disk 4 and the components thereon can be adjusted in the up and down direction, so that the center of the circle of the electric rotating disk 4 is aligned with the center of the circle on the plastic pipe fitting. The telescopic plate 3 is telescoped to drive the right side of the rotating shaft 125, the pull box 127 and the pull rope 124 to adjust the position in the up and down direction. Since the central axis of the rotating shaft 125 is at the same height as the central axis of the rotating disk on the electric rotating disk 4, and the wire groove is at the same height as the center of the rotating disk on the electric rotating disk 4, when the pull rope 124 is in a horizontal state and parallel to the central axis of the plastic pipe fitting, and is at the same height as the central axis of the plastic pipe fitting, it means that the center of the circle of the electric rotating disk 4 is aligned with the center of the circle on the plastic pipe fitting, which can assist in aligning the center of the circle of the electric rotating disk 4 with the center of the plastic pipe fitting, so as to assist in centering the electric rotating disk 4 and the plastic pipe fitting, so as to facilitate centering of the electric rotating disk 4 and the plastic pipe fitting. When the movable clamping plate 24 moves upward to release the plastic pipe fitting, the connecting plate I 121 drives the connecting rod 123 to move to the upper left to reset, and the connecting rod 123 moves to the upper left to pull out the pull rope 124, and the rotating shaft 125 reverses to release the pull rope 124, and the spiral spring 126 continues to compress.

[0042] See also Figure 8-Figure 9 A connecting plate 13 is connected to the rear side of the telescopic end of the telescopic plate 3, and the shape of the connecting plate 13 is L-shaped. An indicator plate 14 is connected to the front side of the connecting plate 13. The indicator plate 14 is at the same height as the central axis of the rotating disk on the electric rotating disk 4. The indicator plate 14 is parallel to the wire groove on the pull box 127 and is at the same height as the wire groove, and is used to indicate the horizontal state of the pull rope 124.

[0043] The indicator board 14 can measure and indicate whether the pull rope 124 is in a horizontal state, so that the operator can check and understand the horizontal state of the pull rope 124, thereby better assisting the alignment of the center of the electric rotating disk 4 with the center of the plastic pipe fitting, making it easier to center the electric rotating disk 4 and the plastic pipe fitting.

[0044] See also Figure 10-11 The workbench 1 is provided with a driving mechanism, which is used to drive the support plate 26 to move up and lift the plastic pipe to pour the waste chips downward. The driving mechanism includes a servo motor 151 connected to the workbench 1. The left side of the workbench 1 is rotatably connected with a spline shaft II 152, and the spline shaft II 152 is connected to the output shaft of the servo motor 151. The U-shaped slide plate 25 is rotatably connected with an adjusting screw rod 153, which is threadedly connected to the support plate 26, and the adjusting screw rod 153 is slidably matched with the workbench 1. The U-shaped slide plate 25 The lower right part is rotatably connected with a spline sleeve II 154, and the spline sleeve II 154 is slidably sleeved on the spline shaft II 152. The spline sleeve II 154 is connected to the adjusting screw rod 153 through a bevel gear set III 155. The bevel gear set III 155 consists of two bevel gears, and the two bevel gears are meshed. A guide plate 156 is connected to the right side of the top of the workbench 1. The guide plate 156 is located on the right side of the fixed clamping plate 21. The shape of the guide plate 156 is an inverted V shape to collect waste chips poured out of the plastic pipe fittings and guide the waste chips to the front and rear sides.

[0045] When the movable clamp 24 moves up to release the plastic pipe fitting, the servo motor 151 is controlled to drive the spline shaft II 152 to rotate, and the rotation of the spline shaft II 152 drives the spline sleeve II 154 to rotate, and the rotation of the spline sleeve II 154 drives the adjusting screw 153 to rotate through the bevel gear set III 155, and the adjusting screw 153 rotates to push the support plate 26 to move up and lift the plastic pipe fitting upward, so that the plastic pipe fitting is in a tilted state with the left side higher and the right side lower, so that the waste chips in the plastic pipe fitting can be poured downward onto the guide plate 156, thereby improving the cleanliness of the plastic pipe fitting and avoiding waste chips remaining in the plastic pipe fitting to affect subsequent use or processing. The waste chips are directed to the front and rear sides by the guide plate 156, and collection frames are placed on the front and rear sides of the guide plate 156 to collect the waste chips. After the waste chips in the plastic pipe are poured out, the servo motor 151 is controlled to drive the spline shaft II 152 to reverse, so that the adjusting screw rod 153 reverses and pushes the support plate 26 to move down and reset, and the plastic pipe moves down and resets to a horizontal state.
