Description

Technical Field

[0001] This utility model relates to the technical field of tooling and fixtures for powder coating, specifically a tooling and fixture for powder coating steel pipes. Background Technology

[0002] Steel pipes refer to steel materials with a hollow cross section whose length is much greater than their diameter or circumference. In order to enhance the corrosion resistance and wear resistance of steel pipes, they usually need to be powder coated. The two ends of the steel pipe are placed between clamps, and the clamps are hung on the lifting device. The lifting device moves the clamps and the steel pipe, and the powder coating device on both sides applies the powder coating.

[0003] Since the clamp is usually composed of a vertical bar and several horizontal bars, one end of the horizontal bar is inserted into the steel pipe and it is simply fixed by the horizontal bar. When the lifting device moves the clamp, the steel pipe is in a slightly swaying state. Under this state, it is very easy to cause uneven powder coating, thus affecting the powder coating quality. Therefore, in order to solve the above problems, a tooling fixture for powder coating of steel pipe is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a tooling fixture for powder coating of steel pipes, so as to solve the problem of uneven powder coating caused by slight shaking of steel pipes during movement.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A tooling fixture for powder coating steel pipes includes a steel pipe body and a fixture body for clamping both ends of the steel pipe body. The fixture body includes a vertical rod, a horizontal rod, and a connecting ring. Several horizontal rods are fixedly connected to one side of the vertical rod, and a connecting ring is fixedly connected to the top of the vertical rod. Clamping components are provided around the horizontal rods. The clamping components include a telescopic rod, a spring, a clamping block, a rubber layer, and a fixing block. Telescopic rods are fixedly connected around the horizontal rods. A spring is provided on the outer side of the telescopic rod. A clamping block with an arc-shaped surface is tightly fitted at one end of the telescopic rod. The steel pipe body is provided on the outer side of the clamping block, and a replacement component is provided on one side of the clamping block.

[0007] Preferably, a rubber layer is fixedly connected to the surface of the clamping block, and the rubber layer is tightly fitted to the inner wall of the steel pipe body.

[0008] Preferably, a fixing block is fixedly connected to one side of the clamping block, and the surface of the fixing block is inclined.

[0009] Preferably, the replacement component includes a positioning block, a threaded sleeve, and a hand-tightening bolt, and grooves are provided on one side of both the clamping block and the rubber layer.

[0010] Preferably, a positioning block is fixedly connected to one side of the telescopic rod, a threaded sleeve is fixedly connected to one side of the positioning block, a hand-tightening bolt is threaded into the threaded sleeve, and one end of the hand-tightening bolt is inserted into the groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this utility model, a clamp body, vertical rod, horizontal rod, connecting ring, steel pipe body, clamping components, telescopic rod, spring, and clamping block are provided. The telescopic rod and spring work together to easily clamp one end of the steel pipe body, making it less prone to shaking during the moving powder coating process. This avoids uneven powder coating caused by the shaking of the steel pipe body. The rubber layer increases the friction between the clamping block and the inner wall of the steel pipe body, thereby improving the clamping effect. The fixing block facilitates the insertion of the clamping block into the inner wall of the steel pipe body. The replacement component positioning block, threaded sleeve, and hand-tightening bolt facilitate the replacement of the spring when it is constantly compressed due to the steel pipe body being fixed, which shortens the spring's lifespan. The groove facilitates the rotation of the hand-tightening bolt. Attached Figure Description

[0020] Please see Figure 1-4 This utility model provides a technical solution:

[0021] A tooling fixture for powder coating steel pipes includes a steel pipe body 2 and a fixture body 1 for clamping both ends of the steel pipe body 2. The fixture body 1 includes a vertical rod 11, a horizontal rod 12, and a connecting ring 13. Several horizontal rods 12 are fixedly connected to one side of the vertical rod 11, and a connecting ring 13 is fixedly connected to the top of the vertical rod 11. Clamping components 3 are provided around the horizontal rods 12. The clamping components 3 include telescopic rods 31, springs 32, clamping blocks 33, rubber layers 34, and fixing blocks 35. The telescopic rods 31 are fixedly connected around the horizontal rods 12. A spring 32 is provided on the outside of the telescopic rod 31. One end of the telescopic rod 31 is tightly fitted with a clamping block 33 with an arc-shaped surface. A steel pipe body 2 is provided on the outside of the clamping block 33. A replacement component 4 is provided on one side of the clamping block 33. The clamping component 3 facilitates clamping and fixing both ends of the steel pipe body 2, making it less likely for the clamping body 1 to shake during the moving powder coating process. This avoids uneven powder coating caused by the shaking of the steel pipe body 2. The replacement component 4 facilitates the replacement of the spring 32 that has lost its elasticity.

[0022] A rubber layer 34 is fixedly connected to the surface of the clamping block 33. The rubber layer 34 is tightly fitted to the inner wall of the steel pipe body 2, increasing the friction between the clamping block 33 and the inner wall of the steel pipe body 2. A fixing block 35 is fixedly connected to one side of the clamping block 33. The surface of the fixing block 35 is inclined to facilitate the placement of the steel pipe body 2. The replacement component 4 includes a positioning block 41, a threaded sleeve 42, and a hand-tightening bolt 43. Grooves 5 are provided on one side of both the clamping block 33 and the rubber layer 34 to facilitate the replacement of the spring 32. A positioning block 41 is fixedly connected to one side of the telescopic rod 31. A threaded sleeve 42 is fixedly connected to one side of the positioning block 41. A hand-tightening bolt 43 is threadedly connected to the threaded sleeve 42. One end of the hand-tightening bolt 43 is inserted into the groove 5 to facilitate the disassembly and assembly of the clamping block 33.

[0023] Workflow: When using the steel pipe powder coating fixture, first place the steel pipe body 2 between the two fixture bodies 1. The user holds the four clamping blocks 33 on the outside of the horizontal bar 12 and moves it towards the horizontal bar 12. The telescopic rod 31 is in its shortest retracted state, and the spring 32 is simultaneously compressed, causing the fixing block 35 to move in the same direction. Then, align one end of the steel pipe body 2 with the fixing block 35 and insert it. The inclined surface of the fixing block 35 facilitates the insertion of the steel pipe body 2. After insertion to the appropriate position, the clamping blocks 33, under the push of the spring 32, cause the surface of the steel pipe body 2 to... The rubber layer 34 is tightly fitted to the inner wall of the steel pipe body 2. The rubber layer 34 increases the friction between the clamping block 33 and the inner wall of the steel pipe body 2, allowing for simple fixation of one end of the steel pipe body 2. The other end of the steel pipe body 2 is fixed in the same way. Then, the two clamping bodies 1 are hung on the lifting device via the connecting ring 13. The lifting device moves the clamping bodies 1 and the steel pipe body 2. The powder coating devices on both sides perform powder coating treatment on them. The clamping assembly 3 makes it difficult for the steel pipe body 2 to shake during the movement and powder coating process. Because the spring 32 is in a compressed state for a long time, its lifespan is reduced. The lifespan is relatively short. When the elasticity of spring 32 gradually fails and it can no longer clamp and fix the inner wall of the steel pipe body 2, it needs to be replaced. The user can place their hand on the outside of the hand-tightening bolt 43 and rotate it through the groove 5 opened in the rubber layer 34 and the clamping block 33. The hand-tightening bolt 43 will rotate and move inside the threaded sleeve 42 until the hand-tightening bolt 43 is completely removed. At this time, the user can hold the clamping block 33 and move it away from the crossbar 12 until it is removed from the outside of the positioning block 41. At this time, the spring 32 can be moved away from the outside of the telescopic rod 31 and away from the crossbar 12. Move until removed, then put the new spring 32 on the outside of the telescopic rod 31, then align the recess on one side of the clamping block 33 with the threaded sleeve 42 and the positioning block 41 and insert it, then fix the clamping block 33 by rotating the hand-tightening bolt 43 in the opposite direction. The clamping component 3 is set to make it easy to clamp and fix both ends of the steel pipe body 2, so that the clamping body 1 drives the steel pipe body 2 to move and spray paint less easily, thereby avoiding uneven spray paint caused by the shaking of the steel pipe body 2. The replacement component 4 is set to make it easy to replace the spring 32 that has failed.
