Embodiment 1

[0021] refer to Figure 1-5 , a kind of equipment for polishing the inner wall of a round steel pipe for mechanical manufacturing, including a throwing rod 1, a plurality of slides 2 distributed in a circular array are provided on the outer wall of one end of the throwing rod 1, and slides 3 are arranged in the slides 2, and the slides 2 There is a guide rod 4 inside, the guide rod 4 runs through the slider 3 and the two ends of the guide rod 4 are respectively fixedly connected with the throwing rod 1, one end of the throwing rod 1 is fixedly installed with an end block 5, and the outer side of one end of the throwing rod 1 is distributed in a circular array. A grinding block 6, a plurality of first connecting rods 7 are hinged on the end block 5, and one end of the first connecting rod 7 is respectively hinged on one side of the bottom of the grinding block 6, and a plurality of second connecting rods 8 are hinged on the top of the slider 3, One end of the second connecting ...

Embodiment 2

[0023] Because in embodiment 1, transmission shaft 15, sealing plate 14, cylindrical body 9, throwing rod 1 are integrally arranged, drive transmission shaft 15 to rotate by external driving device and can drive throwing rod 1 to rotate at high speed, but because sealing plate 14 and cylindrical body 9 are connected by screws, and the force intensity between the sealing plate 14 and the cylinder body 9 is high when rotating at high speed, refer to Figure 1-5 , as another preferred embodiment of the present invention, the difference from Embodiment 1 is that a reinforcement mechanism is provided between the cylinder body 9 and the drive shaft 15, the reinforcement mechanism includes an outer arc plate 17, and the outer arc plate 17 is fixedly connected to Outside the cylinder body 9, the outer circular arc plate 17 is fixedly mounted with a plurality of first lugs 19 facing the side of the transmission shaft 15, the plurality of first lugs 19 are distributed in a circular array...

Embodiment 3

[0025] When the grinding block 6 in Example 1 is working, the grinding block 6 and the inner wall of the round steel pipe need to be closely bonded, so the grinding block 6 is subjected to a downward force perpendicular to the grinding block 6, and the downward force mainly passes through the gap between the screw rod 10 and the cylinder body 9. It is easy to cause damage to the device in the long run, refer to Figure 1-5 , as another preferred embodiment of the present invention, the difference from Embodiment 1 is that the bottom end of the grinding block 6 is provided with a load-bearing mechanism, the load-bearing mechanism includes a straight rail 22, and the straight rail 22 is set on one end of the guide rod 4, and the grinding block 6. A sleeve 23 is fixedly installed at the bottom, and a vertical rod 24 that can move along the sleeve 23 is inserted in the sleeve 23. A roller 25 is installed at the bottom of the vertical rod 24. The roller 25 rolls and is arranged in t...

Abstract

The invention relates to the technical field of polishing equipment for round steel pipes, in particular to a polishing equipment for the inner wall of round steel pipes for mechanical manufacturing. There is a guide rod in the slideway, the guide rod runs through the slider and the two ends of the guide rod are respectively fixedly connected with the throwing rod, one end of the throwing rod is fixedly installed with an end block, and a plurality of grinding blocks are distributed in a circular array on the outside of one end of the throwing rod. A plurality of first connecting rods are hinged on the end block, and a plurality of second connecting rods are hinged on the top of the slider. A rotating shaft is rotatably installed in the center of one end of the cylinder, and a central gear is fixedly installed on the rotating shaft. The open end of the cylinder The sealing plate is connected by screws, and the transmission shaft is fixedly installed on the sealing plate. The transmission shaft is connected with the external drive device, and the rotation of the handle drives multiple grinding blocks to adjust the position synchronously. By synchronously adjusting the positions of multiple grinding blocks, it is suitable for different diameter round steel pipe.

Description

technical field [0001] The invention relates to the technical field of polishing equipment for round steel pipes, in particular to equipment for polishing the inner wall of round steel pipes for mechanical manufacturing. Background technique [0002] There are two ways to polish the inner wall of round steel pipes, one is mechanical polishing, and the other is electrolytic polishing. Mechanical polishing puts the throwing rod into the pipe to drive the impeller or self-made abrasive belt wheel, and then rotates at high speed for polishing. While rotating, the throwing rod is slowly advanced, and the inner wall of the round steel pipe can be polished by polishing equipment to eliminate burrs, so that the pipe wall is more perfect. smooth. [0003] The existing mechanical polishing equipment cannot process round steel pipes with different diameters due to the fixed wheel diameter of the abrasive belt wheel. Therefore, we propose a polishing equipment for the inner wall of rou...
