Description

Technical Field

[0001] The utility model belongs to the technical field of pipe processing equipment, in particular to a stainless steel pipe opening grinding device. Background Art

[0002] After welding, stainless steel pipes often leave obvious weld marks on the pipe mouth. These marks not only affect the appearance, but also may affect the performance and life. Therefore, it is necessary to remove these marks through grinding and polishing to make the pipe mouth surface smooth, flat and beautiful.

[0003] At present, most steel pipes usually need to be manually polished or assisted by a grinding wheel when grinding the pipe ends, resulting in low grinding efficiency. The assistance of the grinding wheel is easy to cause harm to the workers. At the same time, traditional grinding equipment can only grind a single type of steel pipe, resulting in poor adaptability of the equipment and high grinding costs. Utility Model Content

[0004] The purpose of the utility model is to provide a stainless steel pipe mouth grinding device. By setting a fixing mechanism, a grinding mechanism, a motor, and a belt, steel pipes of different diameters can be fixedly ground, avoiding the need to replace equipment, reducing the grinding cost, and can adaptively adjust the contact force between the grinding disc and the steel pipe wall.

[0005] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0007] Furthermore, the fixing mechanism comprises a fixing block, the fixing block is fixedly connected to the outer wall of the turntable, and a threaded rod is rotatably connected to the inner wall of the fixing block.

[0008] Furthermore, one end of the threaded rod away from the turntable is fixedly connected with a twist cap, the surface of the threaded rod is meshingly and rotatably connected with a support rod, and a side of the support rod close to the turntable is fixedly connected with a clamping plate.

[0009] Further, a limiting block is fixedly connected to one end of the support rod close to the threaded rod, and the limiting block is slidably connected to the inner wall of the fixed block.

[0010] Further, the grinding mechanism includes a fixing plate fixedly connected to the top of the fixed rod. A sliding rod is fixedly connected to the upper surface of the fixing plate, and the sliding rods are symmetrically distributed with the fixing plate as the axis.

[0011] Further, the outer surface of one end of the sliding rod away from the fixing plate is provided with a thread. An adjusting nut is rotationally connected in a meshing manner to the threaded surface of the sliding rod.

[0014] 1. By rotating the turning cap to drive the threaded rod to rotate, the support rod moves along the surface of the threaded rod. Under the action of the limiting block, the support rod will not shake during the movement. Since the fixing mechanisms are symmetrically arranged on the outer surface of the turntable, after the movement of one side of the support rod is completed, the support rod on the other side is adjusted by rotating the threaded rod, so that the two groups of support rods move towards each other, so that the clamping plate can be pressed against the outer surface of the steel pipe, and the steel pipe can be effectively fixed on the outer surface of the turntable. In this way, steel pipes of different diameters can be fixed and ground, avoiding the replacement of equipment and reducing the grinding cost.

[0015] 2. By arranging telescopic springs on the outer grinding sheet and the inner grinding sheet, when the surface of the pipe orifice is uneven, it can buffer the outer grinding sheet and the inner grinding sheet, avoiding damage to the outer grinding sheet and the inner grinding sheet caused by direct impact. And when grinding steel pipes of different pipe diameters, under the action of the telescopic spring, the distance between the outer grinding sheet and the inner grinding sheet can be adaptively adjusted, thereby improving the adaptability of the grinding equipment.

[0033] A specific application of this embodiment is as follows:

[0034] When the staff needs to use the device, first use the fixing mechanism 8 to fix the steel pipe 12 on the surface of the turntable 1. Specifically, first rotate the torsion cap 803 to drive the threaded rod 802 to rotate, so that the support rod 804 moves along the surface of the threaded rod 802. Under the action of the limit block 806, the support rod 804 will not shake during the movement. Since the fixing mechanism 8 is symmetrically arranged on the outer surface of the turntable 1, after the movement of one side support rod 804 is completed, the other side support rod 804 is adjusted by rotating the threaded rod 802, so that the two groups of support rods 804 move towards each other, so that the clamping plate 805 can abut against the outer surface of the steel pipe 12, so that the steel pipe 12 can be effectively fixed on the outer surface of the turntable 1. In this way, steel pipes of different diameters can be fixed and polished, avoiding the replacement of equipment and reducing the polishing cost; then the telescopic springs 117 are respectively sleeved on the surface of the slide rod 112, so that the telescopic springs 117 can contact the surface of the stopper 116. Then the inner polishing sheet 115 is sleeved on the surface of the slide rod 112 from the top of the slide rod 112, so that the bottom of the inner polishing sheet 115 can contact the top of the telescopic spring 117, and at the same time ensure that the top of the inner polishing sheet 115 can contact the inner wall of the pipe orifice of the steel pipe 12. Then the outer polishing sheet 114 is installed in the same way as the inner polishing sheet 115, so that the bottom of the outer polishing sheet 114 contacts the outer surface of the pipe orifice of the steel pipe 12. Similarly, another group of telescopic springs 117 are sleeved on the slide rod 112. Finally, rotate the adjusting nut 113 so that the adjusting nut 113 abuts against the telescopic spring 117, so that the outer polishing sheet 114 can be pressed against the outer surface of the steel pipe 12. Thus, the installation between the steel pipe 12 and the polishing mechanism 11 is completed. Finally, start the motor 5, so that the motor 5 drives the belt 7 to drive the driven wheel 2 to drive the rotation of the turntable 1, so that the steel pipe 12 rotates synchronously, so that the steel pipe 12 can be polished by the outer polishing sheet 114 and the inner polishing sheet 115. Since the telescopic springs 117 are arranged on both the outer polishing sheet 114 and the inner polishing sheet 115, when the surface of the pipe orifice is uneven, it can buffer the outer polishing sheet 114 and the inner polishing sheet 115, avoiding damage to the outer polishing sheet 114 and the inner polishing sheet 115 caused by direct impact. And when polishing steel pipes 12 of different pipe diameters, under the action of the telescopic springs 117, the distance between the outer polishing sheet 114 and the inner polishing sheet 115 can be adjusted adaptively, so as to improve the adaptability of the polishing equipment.
