Description

Technical Field

[0001] This application relates to the field of pipeline polishing technology, specifically a polishing apparatus for vacuum pipeline production. Background Technology

[0002] After the pipeline is processed, its surface needs to be polished. Polishing can improve the adhesion of the pipeline surface, making the coating more firm and durable, thereby improving the anti-corrosion spraying effect of the subsequent anti-corrosion layer.

[0003] An existing patent (publication number: CN219666203U) discloses a polishing device for vacuum pipe production, belonging to the field of pipe polishing technology. It includes a base with a strip-shaped groove at its upper end. A lead screw is rotatably connected inside the strip-shaped groove. One end of the lead screw is fixedly connected to a handle, which extends rotatably to the outside of the base. A movable tube is threaded onto the wall of the lead screw. A connecting plate is fixedly connected to the upper end of the movable tube and slidably connected to the inside of the strip-shaped groove. Reinforcing blocks are symmetrically fixedly connected to the upper end of the base. A polishing tube for vacuum pipe polishing is fixedly connected between two reinforcing blocks. A motor is fixedly installed on the upper end of the base, and a turntable is fixedly connected to the motor shaft, extending into the polishing tube. Compared with existing technologies, this device can quickly and effectively polish both the inner and outer walls of the vacuum tube simultaneously.

[0004] However, the position of the polishing block in the above device cannot be adjusted, making it unsuitable for processing pipes of different lengths and diameters. Furthermore, the polishing process easily generates a lot of metal dust, which the device cannot handle. Users are likely to inhale the dust when turning the lead screw, which is harmful to their health. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a polishing apparatus for vacuum pipe production, which has the advantages of high applicability and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a polishing device for vacuum pipe production, comprising a table and two support legs, the top ends of the two support legs being fixedly connected to the bottom of the table, a sliding groove being provided on the upper surface of the table, two symmetrically arranged sliders being slidably connected inside the sliding groove, a fixed frame being provided above each of the two sliders, a rotating shaft being rotatably connected to the side of the two fixed frames that are close to each other, and a three-jaw chuck being fixedly connected to the end of the two rotating shafts that are close to each other;

[0007] The table is equipped with an inverted V-shaped grinding frame, and grinding plates are fixedly connected to both inner walls of the inverted V-shaped grinding frame. The inverted V-shaped grinding frame can be used to grind pipes of different diameters.

[0008] Through the above-described design, the polishing device can firmly fix pipes of different diameters using a three-jaw chuck. The threaded connection design between the slider and the threaded column allows the height of the fixing frame to be adjusted according to actual needs, meeting diverse pipe polishing requirements. Simultaneously, the inverted V-shaped grinding frame design adapts to pipes of different diameters, ensuring consistent and high-quality grinding results. The bidirectional threaded rod design allows the two sliders to move away from or towards each other, achieving precise grinding of pipes of different lengths. The introduction of a motor provides power for the rotation of the rotating shaft and the three-jaw chuck, enabling automatic pipe rotation and improving polishing efficiency. The screw mechanism allows the inverted V-shaped grinding frame to move linearly along the pipe, achieving automatic grinding and polishing. The vacuum cleaner effectively collects dust generated during the grinding process, preventing dust from affecting the working environment and personnel.

[0009] Furthermore, the upper surfaces of both sliders are rotatably connected to two threaded posts, and each of the fixing brackets is threadedly connected to its adjacent threaded post.

[0010] The above solution, through the setting of threaded columns, enables the height adjustment of the fixing frame, thereby improving the overall flexibility.

[0011] Furthermore, motors are fixedly installed on the opposite sides of the two fixed frames, and the output end of each motor is fixedly connected to one end of its adjacent rotating shaft.

[0012] The above scheme, through the setting of the motor, can provide power for the rotation of the rotating shaft and the three-jaw chuck.

[0013] Furthermore, a bidirectional threaded rod is rotatably connected between the two support legs, and the bottom ends of the two sliders are respectively threaded to the two ends of the bidirectional threaded rod.

[0014] The above scheme, through the setting of the bidirectional threaded rod, enables the two sliders to move away from or closer to each other, thereby grinding pipes of different lengths.

[0015] Furthermore, the upper surface of the table is fixedly connected to four bearings arranged in a matrix. Lead screws are rotatably connected between the two frontmost bearings and between the two rearmost bearings. The outer surfaces of the two lead screws are threaded with displacement plates. Electric actuators are installed inside the two displacement plates. The output ends of the two electric actuators are fixedly connected to the bottom of the inverted V-shaped grinding frame.

[0016] With the above scheme and settings, the inverted V-shaped grinding frame can move linearly along the pipe, and the height of the inverted V-shaped grinding frame can be adjusted.

[0017] Furthermore, a shelf is fixedly connected between the bottom ends of the two support legs.

[0018] The above solution, with its storage board, makes it convenient for users to place tools.

[0019] Furthermore, a vacuum cleaner is installed on the upper surface of the shelf, and a vacuum tube is fixedly embedded at the top of the inverted V-shaped grinding frame. The vacuum cleaner's suction end is connected to a corrugated pipe, and the other end of the corrugated pipe is fixedly connected to the vacuum tube.

[0020] The above solution, through the installation of a vacuum cleaner, can collect the dust generated during grinding.

[0021] Furthermore, a control host is installed on one side of the right-side support leg.

[0022] The above scheme, through the settings of the control host, makes it easy for users to control electrical components.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This polishing device for vacuum pipe production features a three-jaw chuck that securely holds pipes of varying diameters. The threaded connection between the slider and the threaded post allows for adjustable height of the mounting frame to meet diverse pipe polishing needs. The inverted V-shaped grinding frame adapts to pipes of different diameters, ensuring consistent and high-quality polishing results. A bidirectional threaded rod allows the two sliders to move closer or further apart, enabling precise polishing of pipes of varying lengths. A motor powers the rotating shaft and three-jaw chuck, automating pipe rotation and improving polishing efficiency. A lead screw allows the inverted V-shaped grinding frame to move linearly along the pipe, achieving automatic polishing. A vacuum cleaner effectively collects dust generated during polishing, preventing dust from affecting the working environment and personnel. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0032] Please see Figure 1 , Figure 2 and Figure 3 This embodiment of a polishing device for vacuum pipe production includes a table 1 and two support legs 2. The tops of the two support legs 2 are fixedly connected to the bottom of the table 1. A groove 3 is provided on the upper surface of the table 1. Two symmetrically arranged sliders 4 are slidably connected inside the groove 3. A fixing frame 5 is provided above each of the two sliders 4. A rotating shaft 6 is rotatably connected to the side of the two fixing frames 5 that is close to each other. A three-jaw chuck 7 is fixedly connected to the end of the two rotating shafts 6 that is close to each other. By setting the three-jaw chuck 7, the purpose of fixing pipes of different diameters can be achieved.

[0033] Please see Figure 1 , Figure 2 and Figure 3 Two fixed brackets 5 are each fixedly mounted with a motor 11 on their opposite sides. The output end of each motor 11 is fixedly connected to one end of the rotating shaft 6 that is close to it. The motor 11 provides power for the rotation of the rotating shaft 6 and the three-jaw chuck 7. Two threaded posts 10 are rotatably connected to the upper surfaces of the two sliders 4. Each fixed bracket 5 is threadedly connected to the threaded post 10 that is close to it. The threaded posts 10 allow for height adjustment of the fixed bracket 5, improving overall flexibility. An inverted V-shaped grinding frame 8 is provided above the table 1. Grinding plates 9 are fixedly connected to the two inner walls of the inverted V-shaped grinding frame 8. The inverted V-shaped grinding frame 8 allows for grinding of pipes of different diameters.

[0034] Please see Figure 1 , Figure 2 and Figure 4 A bidirectional threaded rod 12 is rotatably connected between the two support legs 2. The bottom ends of the two sliders 4 are respectively threaded to the two ends of the bidirectional threaded rod 12. Through the setting of the bidirectional threaded rod 12, the two sliders 4 can move away from each other or closer to each other, thereby polishing pipes of different lengths. Four bearing seats 13 arranged in a matrix are fixedly connected to the upper surface of the table 1. The two bearing seats 13 at the front and the two bearing seats 13 at the back are rotatably connected to the lead screw 14. The outer surfaces of the two lead screws 14 are threadedly connected to the displacement plates 15. Electric push rods 16 are installed inside the two displacement plates 15. The output ends of the two electric push rods 16 are fixedly connected to the bottom of the inverted V-shaped grinding frame 8. Through the above settings, the inverted V-shaped grinding frame 8 can move linearly along the pipe, and the height of the inverted V-shaped grinding frame 8 can be adjusted.

[0035] Please see Figure 1 , Figure 2 and Figure 4 A control unit 21 is installed on one side of the right support leg 2. The control unit 21 allows the user to control the electrical components. A shelf 17 is fixedly connected between the bottom ends of the two support legs 2. The shelf 17 allows the user to place tools. A vacuum cleaner 18 is installed on the upper surface of the shelf 17. A vacuum tube 19 is fixedly embedded at the top of the inverted V-shaped grinding frame 8. The vacuuming end of the vacuum cleaner 18 is connected to a corrugated pipe 20. The other end of the corrugated pipe 20 is fixedly connected to the vacuum tube 19. The vacuum cleaner 18 can collect the grinding dust.

[0036] This embodiment describes a polishing device for vacuum pipe production. Through the three-jaw chuck 7, the device can firmly fix pipes of different diameters. The threaded connection between the slider 4 and the threaded post 10 allows the height of the fixing frame 5 to be adjusted according to actual needs, meeting diverse pipe polishing requirements. Simultaneously, the inverted V-shaped grinding frame 8 adapts to pipes of different diameters, ensuring consistent and high-quality polishing results. The bidirectional threaded rod 12 allows the two sliders 4 to move away from or towards each other, achieving precise polishing of pipes of different lengths. The motor 11 provides power for the rotation of the rotating shaft 6 and the three-jaw chuck 7, enabling automatic pipe rotation and improving polishing efficiency. The lead screw 14 allows the inverted V-shaped grinding frame 8 to move linearly along the pipe, achieving automatic polishing. The vacuum cleaner 18 effectively collects dust generated during polishing, preventing dust from affecting the working environment and personnel.

[0037] The working principle of the above embodiment is as follows: First, the vacuum pipe to be polished is placed on the table 1 and fixed by the three-jaw chucks 7 on the two fixed brackets 5. The three-jaw chucks 7 can tightly hold pipes of different diameters through their internal jaw structure, ensuring their stability during the polishing process. Next, according to the actual diameter of the pipe, the height of the fixed brackets 5 is adjusted by rotating the threaded column 10 above the slider 4. Then, the motor 11 on the fixed brackets 5 is started. The motor 11 drives the rotating shaft 6 and the three-jaw chucks 7 to rotate. While the pipe is rotating, the inverted V-shaped grinding frame 8 is driven to descend by the electric push rod 16, so that the grinding plate 9 on the inner wall of the inverted V-shaped grinding frame 8 contacts the pipe and grinds the pipe. Then, the inverted V-shaped grinding frame 8 is moved in a straight line along the pipe by the drive screw 14 to complete the automatic polishing effect of the pipe. During the polishing process, the vacuum cleaner 18 is connected to the inverted V-shaped grinding frame 8 through the vacuum pipe 19 and the corrugated pipe 20 to effectively collect the metal dust generated during polishing. This not only kept the work environment clean, but also prevented dust from affecting the health of the staff.
