Detailed Description

The technical solutions in the present application will be described in further detail below with reference to the accompanying drawings.

The embodiment of the application discloses a polishing machine. Referring to fig. 1 and 2, a polishing machine includes a frame 11 and a universal wheel 12 rotatably provided at a bottom end of the frame 11 so that a worker can move the frame 11 to a position of a pipe without moving the pipe. A support plate 21 is slidably provided on the frame 11, and a motor 22 is fixedly provided on the support plate 21. A polishing wheel 23 is provided on an output shaft of the motor 22. A through hole for the polishing wheel 23 to pass through is formed in the support plate 21, so that the polishing wheel 23 can pass through the support plate 21 to polish the pipe located below the support plate 21. Be provided with the centre gripping subassembly that is used for the centre gripping pipe fitting on frame 11, can play fixed effect to the pipe fitting for the pipe fitting is difficult for taking place to roll when being handled by the polishing, influences polishing effect.

Referring to fig. 1 and 2, the clamping assembly includes a clamping plate 31 symmetrically disposed on the frame 11 and a spring 32 disposed on the clamping plate 31. The two gripping plates 31 form a gripping space therebetween for gripping the pipe. It should be understood that the number of the springs 32 may be one or more, and the specific number is determined according to the actual length of the clamping plate 31. One end of the spring 32 is fixedly connected with the clamping plate 31, and the other end is fixedly connected with the frame 11. The spring 32 can move the two clamping plates 31 towards each other, and when the pipe is placed between the two clamping plates 31, the spring 32 is compressed, so that the pipe is clamped. The polishing wheel 23 is located at the center of the two holding plates 31, so that when the pipe is held by the two holding plates 31, the polishing wheel 23 is aligned with the axis of the pipe.

Referring to fig. 1 and 2, a guide rod 33 is fixedly disposed on a side of the two clamping plates 31 facing away from each other, and an end of the guide rod 33 facing away from the clamping plates 31 penetrates through the frame 11 and extends outward. The number of the guide rods 33 is the same as the number of the springs 32, and the guide rods 33 correspond to the springs 32 one by one. The guide rod 33 is sleeved in the spring 32 and plays a role in limiting the spring 32, so that the spring 32 is not prone to deflection when being compressed.

Referring to fig. 1 and 2, guide tubes 34 are fixedly disposed on the frame 11, and the number of the guide tubes 34 is the same as that of the guide rods 33. The guide tubes 34 correspond to the guide rods 33 one by one, and the guide rods 33 are slidably arranged in the guide tubes 34. The guide tube 34 increases the contact area with the guide rod 33, and plays a role in limiting and guiding the movement of the guide rod 33, so that the guide rod 33 is not easy to skew in the moving process.

Referring to fig. 2 and 3, a limiting groove 35 is axially formed on the guide rod 33, and the limiting groove 35 is disposed on both sides of the guide rod 33. A limiting block 36 matched with the limiting groove 35 is integrally formed on the inner wall of the guide pipe 34. The limiting block 36 is slidably arranged in the limiting groove 35, so that the guide rod 33 is more stable in moving and is prevented from twisting.

Referring to fig. 1 and 2, in order to improve the clamping effect on the pipe, the clamping plate 31 is an arc-shaped plate matched with the outer wall of the pipe. When the grip block 31 supports the outer wall of the pipe fitting, the grip block can be more attached to the pipe fitting, so that the pipe fitting is not easy to shake when clamped in the middle. A connecting rod 37 is fixedly arranged at one end of the guide rod 33, which is far away from the clamping plate 31, and the connecting rod 37 fixes the guide rods 33 on the same side together, so that when the staff pulls the connecting rod 37, the guide rods 33 on the same side move together.

Referring to fig. 1 and 2, a moving hole 13 for moving the support plate 21 is formed in the frame 11 along the longitudinal direction. Sliding grooves 14 are formed in the frame 11 on both sides of the moving hole 13. Both sides of the support plate 21 are slidably disposed in the slide grooves 14, respectively, so that the support plate 21 can move along the moving hole 13.

Referring to fig. 1 and 2, a plurality of rollers 24 are rotatably disposed on two sides of the support plate 21, and the rollers 24 are disposed in the sliding groove 14, so that the support plate 21 and the sliding groove 14 are changed from sliding friction to rolling friction, and the abrasion to the support plate 21 is reduced.

Referring to fig. 1 and 2, in order to reduce the safety hazard, a protective cover 25 is hinged to the support plate 21. The protective cover 25 can be snapped onto the support plate 21, thereby forming a space for accommodating the polishing wheel 23. When a worker polishes the pipe, the splash of the debris is generated, and the protective cover 25 can block the debris.

The implementation principle of the embodiment of the application is as follows: in use, the frame 11 is moved to the position of the tubular so that the tubular is located below the frame 11. The link 37 is pulled outward, so that the guide bar 33 is moved therewith. The guide bar 33 moves the holding plates 31, and the springs 32 are compressed during the movement of the holding plates 31, so that the space between the two holding plates 31 is enlarged, and the pipe can be placed in the middle. The connecting rod 37 is released, and the clamping plate 31 clamps the pipe in the middle under the driving of the spring 32.

After the tube is clamped in between by the two clamping plates 31, the polishing wheel 23 abuts against the outer wall of the tube. The motor 22 is activated to move the support plate 21 along the moving hole 13, so that the polishing wheel 23 performs a polishing process on the outer wall of the pipe along the axis of the pipe.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
