Description

Technical Field

[0001] The utility model relates to the technical field of PE pipe processing, in particular to a pipe cutting polishing device. Background Art

[0002] PE plastic products are a general term for daily and industrial products made of plastic as the main raw material. They include products made from injection molding, vacuum forming and other processes using plastic as the raw material. Plastic is a type of synthetic polymer material with plasticity. It, along with synthetic rubber and synthetic fiber, forms the three major synthetic materials that are indispensable in daily life. Specifically, plastic is a material that uses natural or synthetic resin as the main component, with various additives added, and can be molded into a certain shape under certain conditions of temperature and pressure, and maintains the same shape at room temperature.

[0003] The announcement number in the existing public technology is: CN213136172U. A cutting and polishing device for PE pipe processing includes four supporting legs, a processing table is fixedly connected between the tops of the four supporting legs, a vertically arranged cylinder is fixedly connected to the middle position of the processing table, the output shaft of the cylinder is vertically downward and fixedly connected to a lifting plate, both sides of the top of the lifting plate are fixedly connected to vertically arranged lifting rods, the top of the lifting rods penetrates the processing table and extends to the top of the processing table and is fixedly connected to a connecting plate, a clamping box is fixedly connected between the sides of the two connecting plates close to each other, and the four corners of the top of the processing table are fixedly connected to support rods. The utility model has an ingenious structure and is easy to use. It can quickly fix the pipe fittings and automatically perform all-round grinding on the edge position of the top incision. It has high grinding efficiency and good grinding effect, and the device can grind pipe fittings of different lengths and diameters.

[0004] However, the above patent still has certain shortcomings when in use: although it can fix the pipe when in use, it lacks a corresponding support structure for the inside of the pipe. When the end of the pipe contacts the grinding wheel, it is easy to cause deformation of the pipe surface due to extrusion or even bending of the pipe, which not only affects the overall grinding quality but also interferes with the subsequent normal use of the pipe. The overall use effect is not very good, and it only clamps the lower part of the pipe, while the upper part lacks support measures, which easily causes the pipe to vibrate during grinding, thereby affecting the overall stability and polishing effect.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0020] (1) The utility model adopts a support tube and an adjustment disk.

[0032] In one embodiment, a plurality of groups of support rings 5 ​​are installed at a position symmetrical to the adjustment disk 11 on one side of the top of the workbench 1, and a fixed cylinder 7 is rotatably connected to the middle position inside the support ring 5. A transmission gear 9 is fixedly installed at the middle position on the surface of the fixed cylinder 7, and a driving gear 4 is meshed and connected to the bottom position of the transmission gear 9. One end of the driving gear 4 is connected to a driving motor 3, and a driving groove 2 for installation is provided on the outer side of the driving motor 3 and the driving gear 4 at the surface of the workbench 1. A plurality of groups of pressure strips 8 are installed around the inside of the fixed cylinder 7, and a first adjusting screw 6 is symmetrically provided on the surface of one side of the pressure strip 8, and one end of the first adjusting screw 6 passes through one side of the fixed cylinder 7. The support ring 5 is provided to support and limit the fixed cylinder 7.

[0033] In one embodiment, a lifting groove 21 is opened below the adjusting disk 11 on the surface of the workbench 1, and electric cylinders 22 are symmetrically installed on both sides of the bottom end of the lifting groove 21. A grinding motor 23 is installed on the top of the electric cylinder 22, and a grinding wheel 24 is installed on the top of the grinding motor 23. The grinding wheel 24 is provided to polish the pipe.

[0034] In one embodiment, support legs 18 are symmetrically installed on both sides of the bottom of the workbench 1, and the entire device can be fixed by the support legs 18, so as to enhance the overall stability in use.

[0035] In one embodiment, a rubber pad is provided on the surface of the pressure strip 8. The rubber pad is provided to increase the friction with the pipe, improve stability, and reduce the extrusion damage to the pipe.

[0036] In one embodiment, the size of the support tube 10 is the same as the inner diameter of the pipe. The support tube 10 is provided to support the inside of the pipe that needs to be polished, to ensure its stability in use, and to avoid deformation or extrusion and bending of the pipe.

[0037] In one embodiment, a guide groove is provided on the surface of the support arm 17 for the movable plate 13 to move. The guide groove is provided to provide a moving space for the movable plate 13 on the one hand, and to limit its movement on the other hand.

[0038] In one embodiment, the size of the insertion rod 12 is the same as the size of the limiting hole 14. The same size is to ensure that the insertion rod 12 can be smoothly inserted into the limiting hole 14, thereby realizing the limiting operation of the adjusting disk 11 after rotation, ensuring that it can remain stable during subsequent use.

[0039] Working principle: In actual use, personnel can directly insert the pipe that needs to be polished into the internal position of the fixed cylinder 7, and expose the part that needs to be polished on the outside of the fixed cylinder 7, and then drive the pressure strip 8 inside the fixed cylinder 7 to move downward by rotating the first adjusting screws 6 on both sides. At this time, the pressure strip 8 can be clamped on the outer surface of the pipe, thereby achieving its fixing operation, avoiding subsequent rotation and deviation during contact, and improving the overall operation stability. Then, the second adjusting screw 19 can be driven to drive the support arm 17 to approach the fixed cylinder 7, and the movable plate 13 can be dragged according to the size of the pipe, so that the insertion rod 12 can be disengaged from the limiting hole 14, and then the adjusting disk 11 is rotated so that the size of the support cylinder 10 on its surface can be the same as the inner diameter of the pipe, and then the movable plate 13 is released. At this time, the reset spring 15 is reset due to the deformation. The insertion rod 12 can be reinserted into the limiting hole 14 to achieve the fixing operation of the adjustment disk 11 to avoid movement during polishing. Then the support tube 10 can be inserted into the internal position of the pipe to achieve the purpose of internal support of the pipe polishing area. In this way, when the grinding wheel 24 contacts the pipe, there is an object supporting the inside, so there will be no bending or large deformation, thereby improving the protection effect of the pipe. At the same time, due to the support, the grinding wheel 24 can also be more fully in contact with the pipe, thereby improving the overall polishing effect. After all preparations are completed, the grinding wheel 24 can be driven to contact the pipe through the lifting operation of the electric cylinder 22. At the same time, the operation of the drive motor 3 and the polishing motor 23 can drive the pipe to rotate and the grinding wheel 24 to rotate, thereby realizing the polishing operation of the pipe. The device as a whole has the advantages of internal support, strong stability and small deformation during polishing.
