Description

Technical Field

[0001] The invention relates to the technical field of pipe processing equipment, and in particular to a plastic pipe end deburring device. Background Art

[0002] Plastic pipes are generally made of synthetic resin, namely polyester, as the main raw material, with stabilizers, lubricants and plasticizers added, and are extruded in a pipe making machine by the "plastic" method. They are mainly used as pipes for tap water supply systems in buildings, drainage, exhaust and sewage sanitary pipes, underground drainage pipe systems, rainwater pipes, and threading pipes for wire installation.

[0003] The processed plastic pipe is cut by a pipe cutting machine to form fixed-length plastic pipe sections. Because the cutting surface of the plastic pipe by the pipe cutting machine is relatively rough, there are many burrs on the end faces of the fixed-length plastic pipe sections, which will affect the use of the plastic pipe sections.

[0004] At present, a grinder is generally used to grind the burrs on the ends of plastic pipes. The plastic pipe is manually rotated to make the circular grinding disc of the grinder perform processing. However, the circular grinding disc is not easy to clean the burrs on the inner wall of the end of the plastic pipe, and the working efficiency is low and the processing quality is poor. Summary of the invention

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a deburring device for the end of a plastic pipe to solve the problem in the prior art that the plastic pipe is processed by a circular grinding disc of a grinder by manually rotating the plastic pipe, but the circular grinding disc is not easy to clean the burrs on the inner wall of the end of the plastic pipe, and the working efficiency is low and the processing quality is poor.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a plastic pipe end deburring device, comprising a workbench, a guide clamping mechanism and an end deburring mechanism arranged on the workbench, the end of the plastic pipe to be processed passes through the guide clamping mechanism and is then embedded in the end deburring mechanism for deburring, and the guide clamping mechanism clamps and fixes the plastic pipe;

[0007] The end deburring mechanism comprises a support plate fixedly connected to the workbench and a mounting plate rotatably arranged on a side of the support plate close to the guide clamping mechanism, and two deburring structures arranged opposite to each other are slidably arranged on a side surface of the mounting plate close to the guide clamping mechanism;

[0008] The two deburring structures are identical and symmetrically arranged, and each deburring structure includes a "U"-shaped block slidably connected to the mounting plate, and the open end of the "U"-shaped block faces the guide clamping mechanism. Adjustment grooves are provided on the inner side walls at both ends of the "U"-shaped block, and each adjustment groove is slidably connected with a grinding sheet inserted inside and outside it, and the grinding sheets are connected to the bottom of the adjustment groove connected to it through multiple elastic telescopic rods.

[0009] Working principle: The end of the plastic pipe to be processed is passed through the guide clamping mechanism, and then the two "U"-shaped blocks are clamped on the inner and outer sides of the end of the plastic pipe to be processed. The two grinding discs in each "U"-shaped block are clamped on the inner and outer sides of the end of the plastic pipe to be processed through the elastic telescopic rod, and the guide clamping mechanism clamps and fixes the plastic pipe at the same time; the mounting plate is rotated to make the two "U"-shaped blocks rotate circumferentially around the end of the plastic pipe to be processed, so as to grind the inner and outer sides of the end of the plastic pipe to be processed.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. This plastic pipe end deburring equipment guides and clamps the feeding of the plastic pipe through the guide clamping mechanism, so that in the process of rotating the mounting plate, the grinding discs in the two "U"-shaped blocks can efficiently grind the inner and outer walls of the plastic pipe end, so that the deburring work of the plastic pipe end can be carried out efficiently and with high quality;

[0012] 2. The grinding sheets are connected to the bottom of the adjustment grooves connected thereto by a plurality of elastic telescopic rods, so that the grinding sheets are attached to the side walls of the plastic pipes to efficiently perform the grinding and deburring work; at the same time, the plurality of elastic telescopic rods can also be telescopically adjusted, so as to perform the grinding and deburring work on plastic pipes with different wall thicknesses.

[0020] The end portion of the plastic tube 23 to be processed is passed through the guide clamping mechanism, and then the two "U"-shaped blocks 4 are clamped inside and outside the end portion of the plastic tube 23 to be processed. The two grinding sheets 6 in each "U"-shaped block 4 are clamped on the inside and outside of the end portion of the plastic tube 23 to be processed by the elastic telescopic rod 7, and the guide clamping mechanism clamps and fixes the plastic tube 23 at the same time; the mounting plate 3 is rotated to make the two "U"-shaped blocks 4 rotate circumferentially around the end portion of the plastic tube 23 to be processed, so as to grind the inside and outside of the end portion of the plastic tube 23 to be processed.

[0021] The plastic pipe end deburring device guides and clamps the feed of the plastic pipe 23 through a guiding and clamping mechanism, so that in the process of rotating the mounting plate 3, the grinding sheets 6 in the two "U"-shaped blocks 4 can efficiently grind the inner and outer walls of the end of the plastic pipe 23, so that the deburring work of the end of the plastic pipe 23 can be carried out efficiently and with high quality; the grinding sheets 6 are connected to the bottom of the adjusting groove 5 connected thereto through multiple elastic telescopic rods 7, so that the grinding sheets 6 are attached to the side wall of the plastic pipe 23 to efficiently carry out the grinding and deburring work; at the same time, the multiple elastic telescopic rods 7 can also be telescopically adjusted, so as to carry out the grinding and deburring work for plastic pipes 23 with different wall thicknesses.

[0022] In this embodiment, the rotation of the mounting plate 3 can be driven by a motor, so that the mounting plate 3 rotates quickly to increase the efficiency of the deburring work of the plastic pipe 23.

[0023] like Figure 2As shown, according to another embodiment of the present invention, in the plastic pipe end deburring device, in order to make the "U"-shaped block 4 quickly clamped on the inner and outer sides of the end to be processed of the plastic pipe 23, the two grinding discs 6 in the "U"-shaped block 4 are against the inner and outer walls of the end to be processed of the plastic pipe 23; it also includes a guide bevel on one side of each grinding disc 6 close to the notch of the "U"-shaped block 4 where it is located, and the guide bevel is used to guide the process of the end to be processed of the plastic pipe 23 being embedded in the "U"-shaped block 4, and the two grinding discs 6 in the "U"-shaped block 4 move away from each other to quickly clamp the side wall of the end to be processed of the plastic pipe 23, thereby improving the efficiency of the feeding process of the plastic pipe 23.

[0024] Combination Figure 2 and Figure 3 According to another embodiment of the present invention, the deburring device for the end of a plastic pipe further includes two linear and spaced guide grooves 8 on one side of the mounting plate 3 close to the guide clamping mechanism, and the outer bottoms of the two "U"-shaped blocks 4 are slidably connected to the two guide grooves 8 in a one-to-one correspondence through sliders; a distance adjustment component is arranged between the two sliders, and the distance adjustment component includes a screw rod 9 rotatably arranged in the mounting plate 3, the screw rod 9 is threadedly connected to the two sliders, one end of the screw rod 9 is driven to rotate by a driver 10, and the other end is provided with an adjustable locking structure connected to the mounting plate 3.

[0025] The adjustable locking structure is adjusted to release the screw rod 9 from the locked state, and the driver 10 drives the screw rod 9 to rotate. The driver 10 can also be a motor, and the two sliders move toward or away from each other on the screw rod 9 to adjust the distance between the two "U"-shaped blocks 4. The plastic pipe end deburring device can also deburr plastic pipes 23 of different diameters.

[0026] Among them, the design purpose of the guide groove 8 is to limit and guide the movement of the slider. After the distance between the two "U"-shaped blocks 4 is adjusted, the adjustable locking structure locks and fixes the screw rod 9 to fix the position of the two "U"-shaped blocks 4, so as to improve the stability of the two "U"-shaped blocks 4 during the deburring process of the plastic pipe 23.

[0027] Specifically, the adjustable locking structure adopted in the present invention includes a stepped groove 11 opened at the end of the screw rod 9, and the cross-sectional area of ​​the groove opening of the stepped groove 11 is smaller than the cross-sectional area of ​​the groove bottom. A locking block 12 is slidably engaged at the large end of the stepped groove 11, and an adjusting rod 13 is connected to the locking block 12, which freely passes through the stepped groove 11 and the mounting plate 3 and is placed outside the mounting plate 3. The adjusting rod 13 and the mounting plate 3 are threadedly connected.

[0028] The end of the adjusting rod 13 that is passed through the outside of the mounting plate 3 is used as a handle to rotate the adjusting rod 13, so that the locking block 12 moves in the big end of the step groove 11 until it abuts against the inner wall of the big end of the step groove 11, and the screw rod 9 is quickly locked and fixed; the adjusting rod 13 is rotated in the opposite direction to make the locking block 12 move in the big end of the step groove 11 until it disengages from the inner wall of the big end of the step groove 11, so that the screw rod 9 is released from the locking fixation, and the screw rod 9 can be rotated by the driver 10.

[0029] Combination Figure 1 and Figure 4 According to another embodiment of the present invention, the deburring device for the end of a plastic pipe further includes structural optimization of a guide clamping mechanism. The guide clamping mechanism used in the present invention includes a guide table 14 connected to the workbench 1, and a guide groove 15 is opened on the top of the guide table 14 along its length direction. The axial direction of the guide groove 15 is parallel to the mid-perpendicular line of the two "U"-shaped blocks 4. The top of the guide table 14 is connected to a support frame 16 clamped above the guide groove 15, and the support frame 16 is connected to a clamping component for clamping and fixing the plastic pipe 23 sliding into the guide groove 15.

[0030] The feeding process of the plastic tube 23 is guided by the guide groove 15 on the guide platform 14. After the positions of the two "U"-shaped blocks 4 are adjusted, the arrangement of the guide groove 15 and the two "U"-shaped blocks 4 is coordinated to make the end of the plastic tube 23 to be processed accurately match the two "U"-shaped blocks 4; then the plastic tube 23 is pressed and fixed by the clamping assembly, so that the plastic tube 23 is stable and motionless during the deburring work, so as to improve the quality of the deburring process.

[0031] Specifically, the clamping assembly used in the present invention includes a mounting bar 17 that is passed through the inside and outside of a support frame 16 and fixedly connected thereto. Both ends of the mounting bar 17 are connected to pressing blocks 19 through a plurality of elastic telescopic connecting rods 18. The pressing blocks 19 are located directly above the guide groove 15. The support frame 16 is also provided with a driving structure that slides in a vertical direction and is used to move the two pressing blocks 19 toward the direction close to the guide groove 15.

[0032] In this embodiment, the support frame 16 is a gantry frame to support and fix the mounting bar 17; the bottom of the pressing block 19 can be designed to be arc-shaped according to the shape of the plastic tube 23 to increase the contact area between the pressing block 19 and the plastic tube 23, so as to achieve the purpose of improving the pressing ability. When the plastic tubes 23 of different diameters are introduced into the guide groove 15, the distance between the pressing block 19 and the guide groove 15 is adjusted by the elastic telescopic connecting rod 18, so that the two pressing blocks 19 are matched with the guide platform 14 to further improve the stability of the plastic tube 23 during the feeding process; when the plastic tube 23 is matched with the two "U"-shaped blocks 4, the driving structure moves to move toward the guide groove 15, and the two pressing blocks 19 are moved toward the guide groove 15 to press and fix the plastic tube 23, and the elastic telescopic connecting rod 18 is extended.

[0033] Here, the driving structure is further optimized to include driving columns 20 that are arranged along the vertical direction at both ends of the mounting bar 17. The lower ends of the two driving columns 20 are against the tops of the two pressing blocks 19 one by one. The tops of the two driving columns 20 are connected by a transmission bar 21 that freely passes through the support frame 16. The support frame 16 is provided with a telescopic adjuster 22 connected to the transmission bar 21. The telescopic adjuster 22 is used to move the transmission bar 21 along the vertical direction.

[0034] The telescopic adjuster 22 can be a cylinder, which provides power to move the transmission bar 21 toward the guide groove 15, so that the two driving columns 20 move toward the guide groove 15, and further move the two pressing blocks 19 toward the guide groove 15 to press and fix the plastic tube 23; when the telescopic adjuster 22 moves in the opposite direction, the pressing block 19 moves in the opposite direction under the elastic restoring force of the elastic telescopic connecting rod 18, so that the processed plastic tube 23 can be removed from the guide platform 14.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
