Description

Technical Field

[0001] The invention relates to the technical field of pipe inner hole polishing, and in particular to a stainless steel pipe inner hole polishing device with precise positioning and a use method thereof. Background Art

[0002] Polishing the inner wall of stainless steel can increase the corrosion resistance of stainless steel. The stainless steel inner hole polishing device generally uses a polishing block to enter the stainless steel for polishing. The stainless steel tube inner hole polishing device needs to align the stainless steel tube with the polishing block so that the polishing block can accurately enter the stainless steel tube. The polishing block is generally driven by a motor through a rotating shaft. The rotating shaft generally needs a certain length to extend into the steel tube. Due to its length, the rotating shaft is easy to bend downward under the action of gravity.

[0003] The defects of the existing pipe inner hole polishing device are: 1. The prior art KR1020140029932A discloses a pipe polishing machine. This technology does not have a structure that automatically aligns the steel pipe with the polishing component, and does not have a structure that automatically measures the position of the stainless steel pipe clamp. Correcting the position of the stainless steel pipe is relatively troublesome. Therefore, a stainless steel pipe inner hole polishing device with precise positioning that can easily align the stainless steel pipe with the polishing component is needed to solve this problem.

[0004] 2. The prior art KR101317285B1 discloses a laser rangefinder, which does not have a dust cleaning function. When the laser emitting end of the laser rangefinder is covered with dust, the measurement effect is easily affected. Therefore, a stainless steel pipe inner hole polishing device with precise positioning for cleaning the emitting end of the laser measuring instrument is needed to solve this problem.

[0005] 3. The prior art KR101357528B1 discloses a fiber-optic based laser rangefinder, which does not have a structure for supporting the bottom of a polishing component with a long rotating shaft. When an additional structure for supporting the rotating shaft is provided, the supporting structure is likely to hinder the movement of the stainless steel pipe because the stainless steel pipe needs to move outside the polishing component. Therefore, a stainless steel pipe inner hole polishing device with precise positioning that can support the rotating shaft of the polishing component and does not hinder the movement of the stainless steel pipe is needed to solve this problem.

[0006] 4. Prior art CN106112784B discloses a fully automatic inner hole polishing machine. This technology does not have a structure for detecting whether the stainless steel pipe is bent. When the stainless steel pipe is bent, the polishing component enters the interior of the stainless steel pipe for polishing, and the inner wall is polished unevenly, which can easily cause damage to the stainless steel pipe. Therefore, a stainless steel pipe inner hole polishing device with precise positioning and the ability to detect whether the stainless steel pipe is bent is needed to solve this problem.

Move the two semicircular plates inwards and fit them together, then extend the polishing pipe into the inner side of the semicircular plates from the rear, then move the push plate forward to push the polishing pipe into the semicircular plates. When the polishing pipe completely enters the semicircular plates, separate the two semicircular plates, and then place the polishing pipe on the inner side of the clamping plate.

[0020] 3. The present invention can measure the distance between the connecting rod and itself through the laser ranging unit 2. When the distance between the connecting rod and the laser ranging unit 2 is greater than the set value, the support wheel moves up to support the rotating rod to prevent the rotating rod from bending downward. When the distance between the connecting rod and the laser ranging unit 2 is less than the set value, the support wheel moves down, so that the polishing pipe will not collide with the pressure measuring plate when moving forward.

[0021] 4. The present invention sets a semicircular plate, and then the push plate pushes the polishing pipe, so that the polishing pipe moves forward along the inner side of the semicircular plate. When the pressure sensing unit 3 detects that the pressure on the push plate increases to the set value, the push plate stops moving, thereby facilitating the judgment that the polishing pipe is bent, thereby avoiding the polishing block from polishing the inner wall of the bent polishing pipe.
