Specific embodiments

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0022] The embodiments of the present utility model will be described below according to its overall structure.

[0023] Please refer to Figures 1-4, A grinding equipment for stainless steel pipes, including a workbench 1 and a clamping mechanism 14. A chute 2 is opened inside the workbench 1, and a bidirectional lead screw 3 is rotatably connected inside the chute 2. A first motor 4 is fixed at the left end of the bidirectional lead screw 3, and a slider 5 is threadedly connected to the outside of the bidirectional lead screw 3. A protection box 6 is fixedly installed at the top of the slider 5, and a second motor 7 is fixed on one side of the protection box 6. The protection box 6 is slidably arranged above the workbench 1 through the slider 5 and the chute 2, and there are two protection boxes 6 arranged parallel to each other. When the first motor 4 is started, the first motor 4 drives the bidirectional lead screw 3 to rotate. Two sliders 5 are threadedly connected to the outside of the bidirectional lead screw 3, and the two sliders 5 approach or move away from each other under the cooperation of the chute 2. Therefore, the distance between the two protection boxes 6 can be changed, which is convenient for processing stainless steel pipes of different lengths. The output end of the second motor 7 is provided with a grinding device 8, and a dust collection box 10 is arranged below the grinding device 8. The other side of the protection box 6 is provided with a feeding port 9. The grinding device 8 is arranged inside the protection box 6, and the output end of the second motor 7 passes through the protection box 6 through a bearing and is fixed to the grinding device 8. The second motor 7 drives the grinding device 8 to rotate. The two ends of the stainless steel pipe are respectively inserted into the two protection boxes 6 through the feeding port 9 until the pipe orifice of the stainless steel pipe is attached to the grinding device 8. The grinding device 8 rotates to polish the pipe orifice of the stainless steel pipe. The two ends of the stainless steel pipe are polished simultaneously, and the polishing efficiency is high. Moreover, the grinding device 8 is arranged inside the protection box 6, which can prevent the polishing waste chips from splashing and improve the safety during polishing. The front surface of the dust collection box 10 is covered with a sealing door 11, and a hinge 12 is arranged at the edge of the sealing door 11. A handle 13 is integrally arranged on the front surface of the sealing door 11, and a transparent observation window is integrally arranged on the front surface of the sealing door 11. It is convenient to understand the polishing situation of the stainless steel pipe through the transparent observation window. When there is a lot of waste chips accumulated inside the dust collection box 10, hold the handle 13 and pull the sealing door 11 forcefully to take out the dust collection box 10 for cleaning, and the operation is very convenient;

[0024] The clamping mechanism 14 is arranged above the middle of the workbench 1. The clamping mechanism 14 includes a vertical plate 1401, a top plate 1402, an electric push rod 1403, an upper clamping plate 1404, a lower clamping plate 1405 and a connecting plate 1406. The top of the vertical plate 1401 is welded with the top plate 1402, and the electric push rod 1403 penetrates through the inside of the top plate 1402. The output end of the electric push rod 1403 is provided with the upper clamping plate 1404, and the lower clamping plate 1405 is arranged below the upper clamping plate 1404. The bottom of the lower clamping plate 1405 is welded with the connecting plate 1406. The bottom of the vertical plate 1401 is welded with the workbench 1, and the vertical plate 1401 is perpendicular to the top plate 1402. The vertical plate 1401 and the top plate 1402 are used to support the electric push rod 1403, the upper clamping plate 1404, the lower clamping plate 1405 and the connecting plate 1406, so as to clamp and fix the stainless steel pipe. The lower clamping plate 1405 is fixed to the front end of the vertical plate 1401 through the connecting plate 1406, and rubber pads are attached to the inner walls of both the lower clamping plate 1405 and the upper clamping plate 1404. The stainless steel pipe is placed inside the lower clamping plate 1405, and the electric push rod 1403 is controlled to lower the upper clamping plate 1404 until the upper clamping plate 1404 abuts against the stainless steel pipe, so that the stainless steel pipe is fixed between the upper clamping plate 1404 and the lower clamping plate 1405. The setting of the rubber pads can prevent the upper clamping plate 1404 and the lower clamping plate 1405 from leaving clamping marks on the surface of the stainless steel pipe.

[0025] Working principle: When in use, first place the stainless steel pipe inside the lower clamping plate 1405, and then start the electric push rod 1403 through the controller arranged at the top of the clamping mechanism 14. The electric push rod 1403 pushes the upper clamping plate 1404 downward until the upper clamping plate 1404 abuts against the stainless steel pipe, so that the stainless steel pipe is fixed between the upper clamping plate 1404 and the lower clamping plate 1405. Start the first motor 4, and the first motor 4 drives the bidirectional lead screw 3 to rotate forward, so that the two sliders 5 threadedly connected to the outside of the bidirectional lead screw 3 approach each other. Therefore, the two protection boxes 6 approach the stainless steel pipe. The two ends of the stainless steel pipe are respectively inserted into the two protection boxes 6 through the feeding ports 9 until the pipe orifice of the stainless steel pipe is attached to the grinding device 8. Drive the grinding device 8 to rotate through the second motor 7. When the grinding device 8 rotates, it grinds the pipe orifice of the stainless steel pipe. The debris generated during the grinding process is intercepted by the protection box 6 and falls into the dust collection box 10. When there is a large accumulation of waste chips inside the dust collection box 10, hold the handle 13 and pull the sealing door 11 forcefully to take out the dust collection box 10 for cleaning.

[0026] The control mode of this device is automatically controlled through the controller. The control circuit of the controller can be realized by simple programming of those skilled in the art, which belongs to the common general knowledge in this field. Therefore, the control mode and circuit connection of this device will not be explained in detail.
