Description

Technical Field

[0001] The utility model relates to the technical field of polishing machines, in particular to a polishing machine for improving the surface finish of a pipe. Background Art

[0002] The pipe polishing machine is equipped with rollers for supporting the pipe. During the polishing operation, the rollers support the pipe, and the grinding wheel and the guide wheel rotate the pipe. Under the friction of the guide wheel, the pipe rotates and moves axially, and the grinding wheel polishes the moving pipe.

[0003] For example, the application publication number is CN205799112U, a pipe polishing machine, including a grinding wheel, a guide wheel, and a roller located below the grinding wheel and the guide wheel, the two ends of the roller center shaft are supported by two rolling bearings respectively, the same end of the roller center shaft is placed between the two rolling bearings, and the two ends of the roller center shaft are provided with a limit mechanism for limiting the axial movement and radial runout of the roller;

[0004] The advantage of the above application is that the size of the rolling bearing used to support the roller is not restricted by the diameter of the roller, and a larger diameter rolling bearing can be used to support a smaller diameter roller, which significantly extends the service life of the roller bearing and improves the durability of the pipe polishing machine. However, it simply places the pipe on the polishing station and uses the reversal of the roller to limit and fix the pipe, but it is not reliable enough to use. During polishing, the pipe can easily shake due to uneven force, affecting the polishing quality. Therefore, the market urgently needs to develop a polishing machine that can improve the surface finish of the pipe to help people solve the existing problems. Utility Model Content

[0005] The purpose of the utility model is to provide a polishing machine for improving the surface finish of pipes, so as to solve the problem proposed in the above background technology that the polishing machine currently used for the surface of pipes simply places the pipes on the polishing station and uses the reverse rotation of the roller to limit and fix the pipes, but it is not reliable enough to use. During polishing, the pipes are easily shaken due to uneven force, which affects the polishing quality.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a polishing machine for improving the surface finish of a pipe, comprising a base, the base being provided with a polishing platform for placing the pipe, the polishing platform being provided with adsorption holes, the base being provided with an air pump, and an air suction pipe being provided between the air pump and the polishing platform for communication.

[0007] Through the above technical scheme, when the surface finish of the pipe is polished, the pipe is placed on the polishing platform, and the bottom of the pipe is supported by the polishing platform. At the same time, the air pump draws air from the inside of the polishing platform through the suction pipe, so that the air flows from the top to the inside of the polishing platform, so that the surface of the polishing platform is in a negative pressure state, and the pipe is firmly adsorbed on the surface of the polishing platform. At the same time, during the rotation of the pipe, the pipe will often separate from the surface of the polishing platform, so that the dust on the surface of the pipe can be sucked away, which plays a role in removing dust from the surface of the pipe, which not only improves the stability of the polishing work, but also plays a role in active cleaning, thereby improving the polishing effect on the surface of the pipe.

[0008] In a preferred example, the utility model can be further configured as follows: a polishing wheel is provided on the base, a first driven wheel is coaxially connected to one side of the polishing wheel, a first motor is provided on the base, a first driving wheel is provided at the output end of the first motor, and the first driving wheel is rotationally connected to the first driven wheel via a belt.

[0009] Through the above technical solution, the first motor is used to drive the first driving wheel to rotate, and the first driving wheel drives the polishing wheel to rotate through the first driven wheel to polish the pipe.

[0010] In a preferred example, the utility model can be further configured as follows: a slide rail is provided on the base, a moving platform is slidably connected to the slide rail, a screw is rotatably connected to the base, and a screw seat threadably connected to the screw is provided below the moving platform.

[0011] Through the above technical solution, the rotation of the screw rod drives the screw rod seat to move horizontally, and the screw rod seat drives the moving platform to move horizontally.

[0012] In a preferred example, the utility model can be further configured as follows: a limiting roller is provided on the mobile platform, a second driven wheel is coaxially connected to one side of the limiting roller, a second motor is provided on the mobile platform, a second driving wheel is provided at the output end of the second motor, and the second driving wheel is rotationally connected to the second driven wheel via a belt.

[0013] Through the above technical solution, the second motor is used to drive the second driving wheel to rotate, and the second driving wheel drives the limiting roller to rotate through the second driven wheel. The rotation direction of the limiting roller is opposite to the rotation direction of the polishing wheel, thereby driving the pipe to rotate and limiting the pipe.

[0014] In a preferred example, the utility model can be further configured as follows: a driven gear is arranged on the outer side of the screw rod, a transmission shaft is rotatably connected to the base, and a second transmission gear is arranged at one end of the transmission shaft and is transmission-connected to the driven gear.

[0015] Through the above technical solution, the transmission shaft is used to transmit power to the screw, and the mobile platform structure is provided with two groups. Both groups of mobile platforms transmit power through the transmission shaft, and there are two transmission shafts with the same structure and function.

[0016] In a preferred example, the utility model can be further configured as follows: a first transmission gear is arranged on the end of the transmission shaft away from the second transmission gear, a driving device is arranged on the base, and a driving gear is arranged at the output end of the driving device and is transmission-connected to the first transmission gear.

[0017] Through the above technical solution, the driving device drives the driving gear to rotate, and the driving gear drives the transmission shaft to rotate through the first transmission gear.

[0020] 1. When the utility model performs surface finish polishing on the pipe, the pipe is placed on the polishing platform, and the bottom of the pipe is lifted up by the polishing platform. At the same time, the air pump draws air from the inside of the polishing platform through the suction pipe, so that the air flows from the top to the inside of the polishing platform, so that the surface of the polishing platform is in a negative pressure state, and the pipe is firmly adsorbed on the surface of the polishing platform. At the same time, during the rotation of the pipe, the pipe will often separate from the surface of the polishing platform, so that the dust on the surface of the pipe can be sucked away, which plays a role in removing dust from the surface of the pipe, which not only improves the stability of the polishing work, but also plays a role in active cleaning, thereby improving the polishing effect on the surface of the pipe.

[0021] 2. The utility model adjusts the lateral position of the limiting roller by setting a movable platform, so that pipes of different diameters can be clamped and limited, so that the polishing machine can be suitable for pipes of different types and diameters, thereby improving the application range of the polishing machine.
