[0002] The stainless steel pipe fittings internal and external wall synchronous polishing device is a processing equipment for stainless steel pipes and fittings. It can polish the inner and outer walls of the fittings simultaneously. This equipment is widely used in the stainless steel pipe manufacturing industry. The polishing device is equipped with polishing wheels to achieve the polishing effect of the inner and outer walls of the stainless steel pipe fittings. The combined use of the two can improve the production efficiency of stainless steel pipe fittings polishing.

[0003] When polishing stainless steel pipe fittings, metal dust will adhere to the surface. If this dust is not cleaned, it will not only affect the polishing effect, but may also harm the operating environment and the health of workers. It increases the friction between the polishing wheel and the surface of the pipe fitting, thereby increasing the risk of scratches on the surface of the pipe fitting. Therefore, a device for simultaneous polishing of the inner and outer walls of stainless steel pipe fittings was designed. Utility Model Content

[0004] The purpose of this invention is to provide a device for simultaneous polishing of the inner and outer walls of stainless steel pipes, in order to solve the problem mentioned in the background art that increases the friction between the polishing wheel and the surface of the pipe, thereby increasing the risk of scratches on the surface of the pipe.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for synchronous polishing of the inner and outer walls of stainless steel pipe fittings, comprising a polishing seat, two support cylinders on the top of the polishing seat, stainless steel pipe fittings placed on the top of the two support cylinders, a first motor on one side of the polishing seat, a threaded rod inside the polishing seat, a displacement block sleeved at one end of the threaded rod, a pressure-resistant seat on the top of the displacement block, a second motor on the top of the pressure-resistant seat, a first polishing wheel whose output shaft is drivenly connected to the second motor, a wetting disc on one side of the first polishing wheel, and multiple absorbent cotton strips on the outer surface of the wetting disc.

[0006] As a preferred embodiment of this utility model, a fixing rod is fixedly installed on one side of the first polishing wheel, and an auxiliary rod is fixedly installed on one side of the wetting disc.

[0010] In a preferred embodiment of this invention, the displacement block is threaded onto one end of the threaded rod, and the output shaft of the first motor is connected to one end of the threaded rod in a transmission manner.

[0011] As a preferred embodiment of this utility model, a second polishing wheel is provided on one side of the polishing seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model incorporates a threaded rod, a displacement block, a fixing rod, an auxiliary rod, a wetting disc, and absorbent cotton strips. The stainless steel pipe is placed on top of two support cylinders. Water is sprayed onto the surface of the multiple absorbent cotton strips, which gradually become wet. Simultaneously, the first and second motors are activated, causing the displacement block to move left and right at one end of the threaded rod, which in turn moves the second motor left and right. The second motor drives the first polishing wheel to rotate, and the outer surface of the first polishing wheel contacts the outer surface of the stainless steel pipe, thus polishing the outer wall of the stainless steel pipe. The wet absorbent cotton strips rub against the outer wall of the stainless steel pipe, providing a moist wiping effect and reducing metal dust generated during polishing, resulting in a more uniform polishing effect.

[0014] 2. This utility model incorporates an anti-pressure seat, limiting strips, recessed holes, and a second polishing wheel. By rotating the two limiting strips in opposite directions, they disengage from the recessed holes and pull the auxiliary rod to one side. The auxiliary rod and the fixed rod are separated, facilitating the individual cleaning of the absorbent cotton strips. As the first polishing wheel rotates, it also drives the wetting tray and multiple absorbent cotton strips to rotate synchronously. The second polishing wheel is located on the inner wall of the stainless steel pipe and is driven by a motor, thus enabling the polishing of the inner wall of the stainless steel pipe.

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution for a device for simultaneous polishing of the inner and outer walls of stainless steel pipe fittings:

[0022] Example 1:

[0023] like Figure 1-3 As shown, a device for synchronous polishing of the inner and outer walls of stainless steel pipe fittings includes a polishing seat 1. Two support cylinders 2 are mounted on the top of the polishing seat 1, and stainless steel pipe fittings 3 are placed on top of the two support cylinders 2. A first motor 4 is mounted on one side of the polishing seat 1. A threaded rod 5 is mounted inside the polishing seat 1, and a displacement block 6 is fitted onto one end of the threaded rod 5. A pressure-resistant seat 7 is mounted on top of the displacement block 6, and a second motor 8 is mounted on top of the pressure-resistant seat 7. The output shaft of the second motor 8 is driven and connected to a first polishing wheel 9. A wetting disc 13 is mounted on one side of the first polishing wheel 9 for wetting... The outer surface of the disc 13 is provided with multiple absorbent cotton strips 14. When the first motor 4 and the second motor 8 are started, the displacement block 6 moves left and right at one end of the threaded rod 5, which in turn moves the second motor 8 left and right. The second motor 8 drives the first polishing wheel 9 to rotate. The outer surface of the first polishing wheel 9 comes into contact with the outer surface of the stainless steel pipe 3, thereby polishing the outer wall of the stainless steel pipe 3. The wet absorbent cotton strips 14 rub against the outer wall of the stainless steel pipe 3, which can wet and wipe it, thereby reducing the metal dust generated during the polishing process.

[0024] Example 2:

[0025] Based on Example 1, such as Figure 1 and Figure 4As shown, the auxiliary rod 11 is movably sleeved with one end of the fixed rod 10. The fixed rod 10 has recessed holes on both sides. The displacement block 6 is threadedly sleeved with one end of the threaded rod 5. The output shaft of the first motor 4 is connected to one end of the threaded rod 5. By setting the anti-pressure seat 7, the limiting strip 12, the recessed hole and the second polishing wheel 15, the two limiting strips 12 are rotated in the opposite direction, so that they are disengaged from the inside of the recessed hole and pulled to one side. The auxiliary rod 11 and the fixed rod 10 are separated from each other, which makes it easy to clean the absorbent cotton strips 14 separately. As the first polishing wheel 9 rotates, it also drives the wetting plate 13 and multiple absorbent cotton strips 14 to rotate synchronously.

[0026] Working Principle: The stainless steel pipe fittings internal and external wall synchronous polishing device is a processing equipment for stainless steel pipes and fittings. It can simultaneously polish the inner and outer walls of the fittings. This equipment is widely used in the stainless steel pipe manufacturing industry. The polishing device is equipped with polishing wheels to achieve the polishing effect of the inner and outer walls of the stainless steel pipe fittings. The combined use of the two can improve the production efficiency of stainless steel pipe fittings polishing. During the polishing of stainless steel pipe fittings, metal dust will adhere to the surface. If this dust is not cleaned, it will not only affect the polishing effect, but may also cause harm to the operating environment and the health of workers. It increases the friction between the polishing wheel and the surface of the fitting, thereby increasing the risk of scratches on the surface of the fitting. To address this, a stainless steel pipe fittings internal and external wall synchronous polishing device is designed. Two support cylinders 2 are driven by a motor. The stainless steel pipe fittings 3 are placed on top of the two support cylinders 2. As the two support cylinders 2 rotate, the stainless steel pipe fittings 3 also rotate. Beforehand, water is sprayed onto the surface of multiple absorbent cotton strips 14, which have the characteristic of absorbing water. Therefore, it gradually becomes moist. At the same time, the first motor 4 and the second motor 8 are started, which drives the displacement block 6 to move left and right at one end of the threaded rod 5, which in turn drives the second motor 8 to move left and right. The second motor 8 drives the first polishing wheel 9 to rotate. The outer surface of the first polishing wheel 9 comes into contact with the outer surface of the stainless steel pipe 3, thereby polishing the outer wall of the stainless steel pipe 3. The moistened absorbent cotton strip 14 rubs against the outer wall of the stainless steel pipe 3, which can moisten and wipe it, thereby reducing the metal dust generated during the polishing process and making the polishing effect more uniform. The two limit strips 12 are rotated in the opposite direction to disengage them from the inside of the concave hole and pull the auxiliary rod 11 to one side. The auxiliary rod 11 and the fixed rod 10 are separated from each other, which makes it easy to clean the absorbent cotton strip 14 separately. As the first polishing wheel 9 rotates, it also drives the wetting plate 13 and multiple absorbent cotton strips 14 to rotate synchronously. The second polishing wheel 15 is located on the inner wall of the stainless steel pipe 3 and is driven by the motor, so it can polish the inner wall of the stainless steel pipe 3.
