[0022] Such as Figures 1-3As shown in the figure: This embodiment provides an anti-rust oil coating device for steel pipe production, including a spraying machine. A receiving box 100 is arranged on the frame of the spraying machine and below the anti-rust oil spraying nozzle. Between the two side walls of the receiving box 100 along the axis direction of the pipe to be sprayed, there are support rods 200. Between the upper parts of the two support rods 200, there is a horizontal spacing adjustment component 300. On the upper part of the horizontal spacing adjustment component 300, there is a vertical spacing adjustment component 400. On the upper part of the vertical spacing adjustment component 400, there is a support component 500 for supporting the pipe to be sprayed. The utility model can effectively support the pipe to be sprayed through the support component 500, and can conveniently and quickly adjust the horizontal position of the support component 500 through the horizontal spacing adjustment component 300, and adjust the spacing of the support component 500 through the vertical spacing adjustment component 400, which is convenient for supporting pipes to be sprayed with different diameters, greatly improving the spraying efficiency and spraying effect of the spraying machine, with stronger applicability, and solving the problem that in the spraying operation process of traditional spraying machines, multiple sets of support rings with different support diameters or different fulcrum positions need to be designed and manufactured, and the specifications and positions of the support rings need to be frequently disassembled and replaced during the spraying operation of pipes to be sprayed with different pipe diameters and lengths to support the pipes to be sprayed during the spraying operation, which is troublesome to operate and greatly reduces the spraying efficiency of the spraying machine.
[0023] According to an embodiment of the present utility model, as Figures 1-3 shown, the horizontal spacing adjustment component 300 includes a first slide rail 301 arranged between the two support rods 200. A first slider 302 is slidably arranged inside the first slide rail 301. Two threaded holes with opposite thread pitches are opened on the axis of the two first sliders 302. A first left-right hand double-threaded screw 303 is threadedly connected in the threaded holes between the two first sliders 302. A first driving motor 304 is arranged on the outer side of the first left-right hand double-threaded screw 303. The utility model can drive the first left-right hand double-threaded screw 303 to rotate through the rotation of the output shaft of the first driving motor 304. Coupled with the threaded connection between the first left-right hand double-threaded screw 303 and the first sliders 302 with opposite thread holes and the guiding and limiting effects of the first slide rail 301 on the two first sliders 302, the rotation of the first left-right hand double-threaded screw 303 can drive the two first sliders 302 to move towards each other along the first slide rail 301 with the vertical spacing adjustment component thereon.
[0024] According to another embodiment of the present utility model, as Figure 1 and Figure 2As shown, the vertical spacing adjustment assembly 400 includes a second slide rail 401 disposed on the upper portion of each first slider 302. A second slider 402 is slidably disposed inside the second slide rail 401. Two threaded holes with opposite thread pitches are formed on the axes of the two second sliders 402. A second left - right hand double - threaded screw 403 is threadedly connected to the threaded holes between the two second sliders 402. A second drive motor 404 is disposed outside the second left - right hand double - threaded screw 403. In the present utility model, the rotation of the output shaft of the second drive motor 404 can drive the second left - right hand double - threaded screw 403 to rotate. Coupled with the threaded connection between the second left - right hand double - threaded screw 403 and the second sliders 402 with opposite thread pitches and the guiding and limiting effects of the second slide rail 401 on the two second sliders 402, the rotation of the second left - right hand double - threaded screw 403 can drive the two second sliders 402 and the support assembly 500 thereon to move towards each other along the second slide rail 401. By adjusting the spacing between the support assemblies 500 on the two first sliders 302 respectively, not only can the support operation during the spraying process of straight pipe fittings be realized, but also the support operation during the spraying process of tapered pipe fittings can be realized, and the operation is more convenient.
[0025] According to another embodiment of the present utility model, as Figure 1 and Figure 3 shown, the support assembly 500 includes a support seat 501 disposed on each second slider 402. A support roller 502 is rotatably disposed on the support seat 501. The support seats 501 on the two second sliders 402 in each second slide rail 401 form a group, which is used to support the outer wall of the pipe fitting to be sprayed and guide its rotation. In the present utility model, the outer wall of the pipe fitting to be sprayed can be effectively supported by the two rotatably disposed support rollers 502, and the rotation operation of the pipe fitting to be sprayed under the action of the driving member is not affected, thereby realizing the coating operation on the entire outer wall of the pipe fitting to be sprayed, and the operation is more convenient.
[0026] On the vertical line where the geometric center of each second slide rail 401 is located, a stop block 503 is disposed. A through - hole larger than the outer - thread diameter of the second left - right hand double - threaded screw 403 is formed on the stop block 503. In the present utility model, the stop block 503 can effectively limit the movement of the fixing seat thereon during the process of the two second sliders 402 moving closer to each other driven by the rotation of the output shaft of the second motor driving the rotation of the second left - right hand double - threaded screw 403, avoiding the two support rollers 502 from rubbing against each other when the distance between them is too close during the approaching process.
[0027] A protective cover 600 is provided at the upper part of the receiving box 100. The height of the protective cover 600 is lower than the lowest point of the support roller 502. The purpose of this is to not affect the support and fixation operation of the pipe fittings to be sprayed. When the length of the pipe fitting to be sprayed is long, the pipe fitting to be sprayed is always located above the protective cover 600.
[0028] The protective cover 600 has a structure with an upper opening larger than the lower opening, and the upper part of the protective cover 600 is located below the anti-rust oil spraying nozzle. The present utility model can effectively block and guide the anti-rust oil falling from the anti-rust oil spraying nozzle through the protective cover 600, so that it smoothly drips into the receiving box 100, avoiding unnecessary waste caused by its splashing everywhere.
[0029] The usage method of the present utility model:
[0030] First of all, it should be clear that the coating device involved in the present utility model is mainly used for the painting or anti-rust oil coating operation of various pipe fittings. Among them, the spraying machine can be a spraying robot in the prior art, or an automatic spray gun arranged under the slider of a linear slide table and connected to an anti-rust oil storage barrel through a hose for spraying operation. During the spraying operation, the pipe fitting to be sprayed is rotatably arranged between two support rollers 502. The rotation mode of the pipe fitting to be sprayed is that a rotation motor can be arranged at the end of the pipe fitting to be sprayed, a speed reducer is arranged at the end of the output shaft of the rotation motor, and a chuck is arranged at the end of the output shaft of the speed reducer. The outer or inner ring of the pipe fitting to be sprayed is fixed through the jaws of the chuck. Then, the output shaft of the rotation motor is started to rotate, thereby driving the pipe fitting clamped by the chuck to rotate, and cooperating with the spraying machine to realize the spraying operation on the entire outer side wall of the pipe fitting located inside the protective cover 600. The present utility model takes the support and fixation of steel pipes of various specifications and dimensions during the anti-rust oil spraying operation in the steel pipe production process as an example to elaborate on its usage method in detail. When it is necessary to spray a steel pipe, first adjust the position of the support rollers 502 according to the diameter and length of the steel pipe. The specific operation method is as follows: Start the output shaft of the first driving motor 304 to rotate. The rotation of the output shaft of the first driving motor 304 drives the first left-right thread double screw 303 to rotate. Coupled with the threaded connection between the first left-right thread double screw 303 and the two first sliders 302 with opposite threaded holes, as well as the guiding and limiting effects of the first slide rail 301 on the two first sliders 302, the rotation of the first left-right thread double screw 303 can drive the two first sliders 302 to move towards each other along the first slide rail 301 with the vertical spacing adjustment assembly thereon. Then, start the output shaft of the second driving motor 404 to rotate. The rotation of the output shaft of the second driving motor 404 drives the second left-right thread double screw 403 to rotate. Coupled with the threaded connection between the second left-right thread double screw 403 and the two second sliders 402 with opposite threaded holes, as well as the guiding and limiting effects of the second slide rail 401 on the two second sliders 402, the rotation of the second left-right thread double screw 403 can drive the two second sliders 402 to move towards each other along the second slide rail 401 with the support assembly 500 thereon, facilitating the effective support operation of the support assembly 500 for pipe fittings to be sprayed with different diameters and lengths. The present utility model can effectively support the pipe fitting to be sprayed through the support assembly 500, and can conveniently and quickly adjust the horizontal position of the support assembly 500 through the horizontal spacing adjustment assembly 300, and adjust the spacing of the support assembly 500 through the vertical spacing adjustment assembly 400, facilitating the support operation for pipe fittings to be sprayed with different diameters, greatly improving the spraying efficiency and spraying effect of the spraying machine, with stronger applicability, and solving the problem that in the traditional spraying operation process, multiple sets of support rings with different support diameters or different fulcrum positions need to be designed and manufactured.During the spraying operation of workpieces to be sprayed with different pipe diameters and lengths, it is necessary to frequently disassemble and replace the specifications and positions of the support rings to achieve the support operation of the workpieces to be sprayed during the spraying operation. The operation is troublesome, which greatly reduces the spraying efficiency of the spraying machine.
[0031] In addition, it should be noted that in the description of the present invention, unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
[0032] The above is the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle described in the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
