A fixing tool for magnetically suspending and polishing long material pipe

Abstract

This utility model belongs to the field of non-ferrous metal processing technology, and specifically discloses a fixture for fixing long tubes for magnetic levitation polishing. It includes a left hanger and a right hanger on the right side of the left hanger. Limiting rods are fixed at the front and rear ends of the bottom of the left hanger and the right hanger, respectively. Sleeve plates are movably sleeved on both sides between the two limiting rods, and eight sets of sleeves are fixed at the bottom of the sleeve plates. This fixture for fixing long pipes used in magnetic levitation polishing consists of eight sets of sleeves fixed to the bottom of a sleeve plate. First, the left and right hangers are vertically fixed above the polishing equipment. Then, a horizontal frame and limiting rods are assembled, and each pipe is placed horizontally between symmetrical cantilever rods. The motor is started and the worm gear is rotated, which in turn engages and pushes the worm wheel below, causing the screw to rotate in the horizontal frame. This guides the symmetrical threaded blocks on both sides to move in opposite directions, and the spacing of the sleeve plate and each connector is adjusted. This allows the cantilever rods to be inserted and fixed from both sides of the pipe with rubber sleeves. The insertion spacing is adjustable, which also facilitates the installation or removal of the pipe. It is a split-type fixing fixture that solves the problem of inconvenient pipe disassembly and installation.

Description

Technical Field

[0001] This utility model relates to the field of non-ferrous metal processing technology, specifically to a fixture for fixing long tubes for magnetic levitation polishing. Background Technology

[0002] Currently, solution heat-treated pipes often have a black oxide film and residual black and oil spots on their surface, especially noticeable on 2-series, 6-series, and 7-series pipes. This affects the accuracy of subsequent eddy current testing and functional testing requirements. A common method is to use alkaline etching to remove the oxide film, black spots, and oil spots from the pipe surface, followed by rinsing with water to remove any alkaline corrosion residue. However, due to the long pipe length and small inner diameter, some alkaline corrosion solution may remain inside the pipe, posing a risk of internal corrosion.

[0003] Magnetic levitation polishing uses a solution of polishing fluid and water, which eliminates the risk of corrosion. However, long pipes cannot be accurately positioned in the polishing fluid, and the pipes are easily scratched and damaged during the polishing process. Most of the previous fixed fixtures have fixed specifications, which are inconvenient to change and difficult to adjust according to the length of the pipes, making them quite limited in use.

[0004] Now, a novel fixture for fixing long tubes used in magnetic levitation polishing is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a fixture for fixing long tubes used in magnetic levitation polishing, so as to solve the problem of inconvenient disassembly and installation of tubes mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fixture for fixing long tubes for magnetic levitation polishing, comprising a left hanger, a right hanger on the right side of the left hanger, limit rods fixed at the front and rear ends of the bottom of the left and right hangers respectively, sleeve plates movably sleeved on both sides between the front and rear limit rods, and eight sets of sleeves fixed at the bottom of the sleeve plates, cantilever rods at the bottom of the sleeves, and a tube at the center between the two cantilever rods, through grooves horizontally provided at the front and rear ends of the sleeve plates, a threaded block fixed at the center of the top of the sleeve plates, and threaded grooves provided between the left and right sides of the threaded block, a horizontal frame fixed at the center between the left and right hangers, and a screw movably connected between the left and right sides of the horizontal frame, a hollow groove provided at the center of the left hanger, and a worm gear movably connected between the front and rear sides of the upper part of the hollow groove, and a worm wheel movably connected between the left and right sides of the lower part of the hollow groove, and a motor fixed at the front end of the left hanger.

[0007] As a further technical solution of this utility model, the output end of the motor is fixedly connected to the worm gear at the rear, and the right side of the worm wheel is fixedly connected to the screw.

[0008] As a further technical solution of this utility model, the limiting rod is horizontally embedded between the through slots of the sleeve plate, and the screw is horizontally embedded in the threaded groove of the threaded block.

[0009] As a further technical solution of this utility model, a rod is fixed to the top of the cantilever rod, a screw hole is provided between the upper and lower parts inside the front end of the sleeve, a bolt is threaded into the screw hole, a slide is longitudinally provided on the side wall of the sleeve, and a balance bar is fixed at the center between the rods on both sides.

[0010] As a further technical solution of this utility model, the rod moves longitudinally along the inner wall of the sleeve, and both sides of the balance bar slide along the slide rail.

[0011] As a further technical solution of this utility model, a short rod is fixed to the side of the bottom of the cantilever rod, and a rubber sleeve is fixed to the outside of the short rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the fixture for fixing long pipes for magnetic levitation polishing not only facilitates the hoisting of pipes and the adjustment of the processing height of pipes, but also adapts to different pipe diameters;

[0013] (1) By fixing eight sets of sleeves at the bottom of the sleeve plate, first fix the left hanger and the right hanger vertically above the polishing equipment, then assemble the horizontal frame and limit rod, etc., place each pipe horizontally between the symmetrical cantilever rods, start the motor and rotate the worm gear, thereby meshing and pushing the worm wheel below, so that the screw rotates in the horizontal frame, guides the symmetrical threaded blocks on both sides to move in opposite directions, and adjusts the spacing of the sleeve plate and each plug-in part, so that the cantilever rod can be plugged and fixed from both sides of the pipe with rubber sleeves, and the plug-in spacing can be adjusted, which is also convenient for installing or disassembling the pipe. It is a split-type fixing tool.

[0014] (2) By fixing the rods at the top of the cantilever, if the fixed fixture and pipe are far or too close to the polishing equipment, it is necessary to hold each balance rod in advance so that it can move up and down the rods in each sleeve along the slide to adjust the height of the cantilever and pipe. After aligning with the screw holes on the surface, screw in the bolts to lock it. This can change the distance between the pipe and the polishing tank in the longitudinal direction, avoid the distance being too large and making it difficult to polish the pipe wall, and facilitate the universality and interchangeability of the pipe polishing.

[0015] (3) By fixing rubber sleeves on the outside of the short rod, each rubber sleeve is fitted onto the short rod on the side of the cantilever rod. The rubber sleeves have good elasticity and can be squeezed into the inside of pipes of different diameters. When its surface contacts the inner wall of the pipe, it will generate a large frictional resistance, which will prevent the pipe from shifting during the polishing process, prevent the pipe from falling off the fixed fixture, and facilitate disassembly and cleaning.

Detailed Implementation

[0021] 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.

[0022] Please see Figure 1-4This utility model provides an embodiment of a fixture for fixing long tubes used in magnetic levitation polishing, comprising a left hanger 11, a right hanger 17 on the right side of the left hanger 11, limit rods 15 fixed at the front and rear ends of the bottom of the left hanger 11 and the right hanger 17 respectively, sleeve plates 16 movably sleeved on both sides between the front and rear limit rods 15, and eight sets of sleeves 6 fixed at the bottom of the sleeve plates 16, with cantilever rods 4 at the bottom of the sleeves 6, and a tube 1 at the center between the two cantilever rods 4, with the front and rear ends of the sleeve plates 16 respectively... A through groove 9 is provided horizontally. A threaded block 13 is fixed at the center of the top of the sleeve plate 16. A threaded groove 23 is provided between the left and right sides inside the threaded block 13. A horizontal frame 12 is fixed at the center between the left hanger 11 and the right hanger 17. A screw rod 14 is movably connected between the left and right sides inside the horizontal frame 12. A hollow groove 19 is provided at the center of the left hanger 11. A worm gear 20 is movably connected between the front and back sides of the upper part of the hollow groove 19. A worm wheel 21 is movably connected between the left and right sides of the lower part of the hollow groove 19. A motor 10 is fixed at the front end of the left hanger 11.

[0023] The output end of the motor 10 is fixedly connected to the worm gear 20 at the rear, the right side of the worm wheel 21 is fixedly connected to the screw 14, the limiting rod 15 is horizontally embedded in the through groove 9 of the sleeve plate 16, and the screw 14 is horizontally embedded in the thread groove 23 of the threaded block 13.

[0024] Specifically, such as Figure 1 and Figure 2 As shown, the left hanger 11 and the right hanger 17 are first vertically fixed above the polishing equipment. Then, the horizontal frame 12 and the limiting rod 15 are assembled. Each pipe 1 is placed horizontally between the symmetrical cantilever rods 4. The motor 10 is started and the worm gear 20 is rotated, thereby engaging and pushing the worm wheel 21 below, so that the screw 14 rotates in the horizontal frame 12, guiding the symmetrical threaded blocks 13 on both sides to move in opposite directions. The spacing of the sleeve plate 16 and each plug-in part is adjusted to facilitate the plug-in fixing of the cantilever rod 4 with the rubber sleeve 2 from both sides of the pipe 1.

[0025] A rod 5 is fixed to the top of the cantilever rod 4. A screw hole 7 is provided between the upper and lower parts inside the front end of the sleeve 6. A bolt 8 is threaded into the screw hole 7. A slide rail 22 is provided longitudinally on the side wall of the sleeve 6. A balance bar 18 is fixed at the center between the two rods 5. The rod 5 moves longitudinally along the inner wall of the sleeve 6. Both sides of the balance bar 18 slide along the slide rail 22.

[0026] Specifically, such as Figure 1 and Figure 3As shown, if the fixed fixture and pipe 1 are too far away from the polishing equipment or too close, it is necessary to hold each balance bar 18 in advance so that it moves along the slide 22 in each sleeve 6 to raise and lower the bar 5, so as to adjust the height of the cantilever bar 4 and pipe 1, etc. After aligning with the screw hole 7 on the surface, screw in the bolt 8 to lock it, which can change the distance between the pipe 1 and the polishing tank longitudinally.

[0027] A short rod 3 is fixed to the side of the bottom of the cantilever rod 4, and a rubber sleeve 2 is fixed to the outside of the short rod 3;

[0028] Specifically, such as Figure 1 and Figure 4 As shown, each rubber sleeve 2 is respectively fitted onto the short rod 3 on the side of the cantilever rod 4. The rubber sleeve 2 has a good elastic effect and can be squeezed into the inside of the pipe 1 of different diameters. When its surface contacts the inner wall of the pipe 1, it will generate a large frictional resistance, which will prevent the pipe 1 from shifting during the polishing process and also prevent the pipe 1 from falling off the fixed fixture.

[0029] Furthermore, the motor 10 is electrically connected to an external PLC control module to control the start and stop of the motor 10 and preset relevant parameters. The electrical connection relationship and control method between them are existing technologies and will not be described in detail.

[0030] Working Principle: In use, the rubber sleeves 2 are first fitted onto the short rods 3 on the sides of the cantilever rods 4. The rubber sleeves 2 have good elasticity and can be squeezed into the interior of pipes 1 of different diameters. When their surfaces contact the inner wall of the pipe 1, they generate significant frictional resistance, preventing displacement of the pipe 1 during polishing. Then, the left hanger 11 and right hanger 17 are vertically fixed above the polishing equipment. Next, the horizontal frame 12 and limiting rod 15 are assembled, and the pipes 1 are horizontally placed between the symmetrical cantilever rods 4. The motor 10 is started and the worm gear 20 is rotated, thereby engaging and pushing the lower worm wheel 21, causing the worm to... The rod 14 rotates in the horizontal frame 12, guiding the symmetrical threaded blocks 13 on both sides to move in opposite directions, and adjusting the spacing of the sleeve plate 16 and each plug-in component, so that the cantilever rod 4 can be plugged and fixed from both sides of the pipe 1 with the rubber sleeve 2, and the plug-in spacing can be adjusted. If the fixing fixture and the pipe 1 are far away from the polishing equipment or too close, it is necessary to hold each balance rod 18 in advance, so that it moves up and down the rod 5 in each sleeve 6 along the slide 22, so as to adjust the height of the cantilever rod 4 and the pipe 1, etc. After aligning with the screw hole 7 on the surface, screw in the bolt 8 to lock it, which can change the distance between the pipe 1 and the polishing groove in the longitudinal direction, avoiding the distance being too large and making it difficult to polish the pipe wall.
