Description

Technical Field

[0001] This utility model relates to the field of pipe grinding technology, specifically to a grinding device for polyethylene pipes. Background Technology

[0002] In the application of polyethylene pipes, when the length of a single pipe is insufficient, it is often necessary to splice two pipes together. The quality of splicing directly affects the connection strength and service life of the pipes. Therefore, it is necessary to grind the outer and inner edges of the pipes to improve the bonding strength.

[0003] Traditional splicing mainly relies on manual grinding, and some grinding is done by grinding equipment. Manual grinding requires operators to hold tools for a long time, which is labor-intensive. It is difficult to guarantee the accuracy of manual grinding, and uneven grinding or over-grinding is likely to occur. At the same time, most grinding equipment can only grind the outer or inner side, and cannot meet the grinding needs of both the inner and outer sides at the same time. Utility Model Content

[0004] To achieve the above objectives, the present invention provides the following technical solution: a grinding device for polyethylene pipes, comprising a frame, a sliding frame slidably connected to the inner side of the frame, a translation component for driving the sliding frame to move, multiple sets of V-shaped plates installed on the top of the sliding frame, a side frame installed on the right side of the sliding frame, a pushing and rotating part installed on the side frame, a pneumatic chuck installed at the shaft end of the pushing and rotating part, an adjustment component installed on the left side of the frame, and a grinding device installed on the adjustment component;

[0005] The adjustment assembly includes a side-mounted cylinder hinged to the side of the frame. The piston rod of the side-mounted cylinder is hinged to an L-shaped plate, which is also hinged to the frame. One end of the L-shaped plate is hinged to a connecting rod, and one end of the connecting rod is hinged to a support plate. The top of the support plate is fixed with an upper seat that is hinged to the frame. The grinding device is mounted on the upper seat.

[0006] Furthermore, the pushing and rotating part includes a movable module mounted on the side frame, the movable end of the movable module is fixed with a base box, the pneumatic chuck is rotatably mounted on the base box, and a belt-driven drive device that is connected to the shaft end of the pneumatic chuck is installed inside the base box.

[0007] Furthermore, the translation component includes a drive motor mounted on the frame, a gear fixed to the shaft end of the drive motor, and a rack that meshes with the gear fixed to the bottom of the side crossbar of the sliding frame.

[0008] Furthermore, each of the V-shaped plates has several omnidirectional balls installed on its surface.

[0009] Furthermore, the multiple sets of V-shaped plates are fixed together by connecting plates, and the bottom sides are all hinged to the sliding frame. An ejector cylinder is hinged to the inner side of the sliding frame, and the piston rod of the ejector cylinder is hinged to the other side of the bottom of the middle V-shaped plate.

[0010] Furthermore, the top of the frame is hinged to a lifting frame and a fixed support frame on the front and rear sides of the V-shaped plate, respectively.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0012] The grinding device for this polyethylene pipe supports the pipe body via a V-shaped plate. Then, a pusher rotating part drives a pneumatic chuck to move to the inside to fix the pipe body. Simultaneously, a side-mounted cylinder operates, and with the cooperation of an L-shaped plate, connecting rod, and support plate, pushes the upper seat to adjust the position of the grinding end of the grinding device. Depending on the needs, it can be adjusted to grind the inside or outside of the pipe. The translation component drives the sliding frame to move, so that the pipe opening is in contact with the grinding end. The pusher rotating part drives the pipe body to rotate via the pneumatic chuck to complete the grinding. Therefore, one device can complete the grinding of the inside or outside of the pipe body, improving the practicality of the equipment. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3This embodiment of a polyethylene pipe edge grinding device includes a frame 1, an upper seat 19 hinged to the top left side of the frame 1, and an adjustment component fixed to the upper seat 19 on the left side. A grinding device 20 is installed on the top of the upper seat 19. The grinding device 20 includes a belt grinder, a long frame, a baffle, and guide wheels. The guide wheels are installed inside the long frame, and the long frame and the belt grinder are installed on the upper seat 19. The long frame and the guide wheels are connected to the belt grinder in a transmission connection. The baffle is installed on the top of the long frame. A sliding frame 7 is slidably connected to the inner side of the frame 1, and a translation component for driving the sliding frame 7 to move is also installed on the frame 1. Three sets of V-shaped plates 11 are installed on the top of the sliding frame 7, and a side frame 2 is fixed on the right side of the sliding frame 7. A pushing and rotating part is installed on the side frame 2, and a pneumatic chuck 5 is installed on the shaft end of the pushing and rotating part.

[0019] In the above structure, the three sets of V-shaped plates, due to their V-shaped design, contact the tube surface, effectively preventing the tube from rolling and ensuring its stability during processing. The pushing and rotating part drives the pneumatic chuck to move to the inside of the tube. The pneumatic chuck opens and fixes the tube from the inside. The adjusting component drives the upper seat to move up or down, thus the upper seat can drive the grinding device to adjust the angle. When the appropriate angle is adjusted, the translation component drives the sliding frame to advance, so that the grinding end of the grinding device is in contact with the inside or outside of the tube. When the grinding device is running, the pushing and rotating part drives the pneumatic chuck to rotate, so that the tube rotates to complete one revolution of grinding. Therefore, the grinding of the inside and outside of the tube can be completed with one machine, improving practicality.

[0020] Meanwhile, when it is necessary to increase the grinding depth of the inner and outer sides of the tube, the translation component drives the sliding frame to move back and forth left and right according to the grinding depth requirements. At the same time, the push rotating part drives the tube to rotate and complete one round of grinding. Therefore, it is suitable for different grinding depth requirements.

[0021] The top of the frame 1 is hinged to the front of the V-shaped plate 11 with a lifting frame 21. The pipe can be placed on the lifting frame first. When the lifting frame is pushed up and forms a slope, the pipe will roll between the three sets of V-shaped plates to complete the pipe loading operation.

[0022] Meanwhile, several universal balls 14 are installed on the surface of the three sets of V-shaped plates 11. When the pipe rotates, the universal balls reduce friction with the pipe, making the pipe rotate more smoothly.

[0023] In addition, the three sets of V-shaped plates 11 are fixed together by connecting plates 12, which are also V-shaped to match the V-shaped plates 11. One side of the bottom back of the V-shaped plate 11 is hinged to the sliding frame 7. The inner side of the sliding frame 7 is hinged to the ejector cylinder 13, and the piston rod of the ejector cylinder 13 is hinged to the front side of the bottom of the middle V-shaped plate 11. A support frame 22 is fixed to the back of the frame 1. After the pipe is ground, the ejector cylinder pushes the V-shaped plate upward. Under the action of the connecting plate, the V-shaped plate moves together and tilts. Then, with the help of the universal ball, the pipe can be rolled onto the support frame to complete the unloading operation.

[0024] like Figure 1 The pushing and rotating part includes a movable module 3 fixed to the top of the side frame 2. A base box 4 is fixed to the movable end of the movable module 3. A pneumatic chuck 5 is rotatably connected to the base box 4. A belt-driven drive device 6 for driving the pneumatic chuck 5 to rotate is installed in the base box 4. When the tube is placed on the V-shaped plate, the movable module drives the base box to move and advance, causing the chuck of the pneumatic chuck to open inside the tube and fix the tube from the inside. Then, the belt-driven drive device drives the pneumatic chuck to rotate, thereby driving the tube to rotate.

[0025] like Figure 3 The adjustment assembly includes a side-top cylinder 15, an L-shaped plate 16, a connecting rod 17, and a support plate 18. The side-top cylinder 15 is hinged to the left side of the frame 1, and its piston rod is hinged to the long end of the L-shaped plate 16. The L-shaped plate 16 and the frame 1 are hinged to form a rotation fulcrum. The short end of the L-shaped plate 16 is hinged to the connecting rod 17, and the other end of the connecting rod 17 is hinged to the support plate 18. The support plate 18 is fixed to the upper seat 19. By pushing or pulling the side-top cylinder upwards or backwards, the L-shaped plate can be driven, and the support plate can be moved upwards or downwards through the connecting rod. Therefore, the upper seat can be moved in a fan shape to adjust the angle, thereby adjusting the grinding end of the grinding device. Therefore, when the tube body is fixed, when it is necessary to grind the inner side of the tube body, the grinding end is first moved to the inner side of the tube body, and can also be moved to the top of the tube body. Then, by pushing the translation assembly, the tube body is pushed to the appropriate position, and the side-top cylinder drives the upper seat to adjust until the grinding end of the grinding device is in contact with the inner or outer side of the tube body.

[0026] like Figure 2 The translation component includes a drive motor 9, a gear 10, and a rack 8: the drive motor 9 is fixed to the front of the frame 1, and its output shaft is fixedly connected to the gear 10. The bottom of the side crossbar of the sliding frame 7 is fixed with a rack 8 that meshes with the gear 10. Driven by the drive motor, the gear rotates, and the gear meshes with the rack to drive the sliding frame to move. Therefore, the tube is moved closer to the grinding end. At the same time, the drive motor can reciprocate to drive the sliding frame to move back and forth. Therefore, the grinding operation can be completed by adjusting the grinding depth.

[0027] The working principle of the above embodiments is as follows:

[0028] First, place the tube onto the lifting frame. Pushing the frame upwards tilts it, causing the tube to roll down the slope until it lands on the V-shaped plate and connecting plate. The V-shape acts as a limit, ensuring a smooth landing between the V-shaped plate and connecting plate. The ball joint contacts the tube, and the moving module moves the pneumatic chuck to the inside of the tube to open and secure it. Simultaneously, the side-mounted cylinder operates, driving the L-shaped plate, connecting rod, and support plate to move the upper seat up and down, adjusting the position of the grinding device. After adjustment, the drive motor operates, using gears and racks to move the sliding frame, allowing the tube to move to the appropriate position. The tube body is positioned so that it is aligned with the grinding end. Then, the belt drive drives the pneumatic chuck to rotate, thus rotating the tube body to cooperate with the grinding process. When it is necessary to adjust the inner and outer grinding, the sliding frame retracts, and the adjustment component adjusts the angle of the grinding device. After the adjustment is completed, the translation component drives the sliding frame to push out again, cooperating with the grinding device and the belt drive. Therefore, the grinding process of both sides can be completed by one machine. After the grinding is completed, the ejector cylinder ejects, tilting the V-shaped plate and connecting plate. Thus, the tube body rolls down onto the support frame with the assistance of the universal ball to complete the unloading.
