Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example
[0027] A stainless steel pipe internal and external grinding machine comprises a frame 1, a movable frame 2 is penetrated on one side of the frame 1, a terminal 3 is sleeved on one end of the movable frame 2, a fixing part 4 fixedly mounted on the movable frame 2 is arranged on one side inside the terminal 3, rollers 5 distributed at equal intervals are embedded and movably mounted on the surface of the fixing part 4, one side of the rollers 5 is embedded and movably mounted on the inner wall of the terminal 3, a gear ring 9 is fixedly connected to one side of the terminal 3, a mounting frame 6 is fixedly mounted on one side of the movable frame 2, a stepping motor 7 is detachably mounted on one side of the mounting frame 6, a gear 8 meshing with the gear ring 9 is fixedly mounted on the output shaft of the stepping motor 7, and a grinding component is embedded and movably mounted on the surface of the terminal 3.
[0028] The specific use process is as follows: First, the user adjusts and unfolds the clamping rod 182 and the clamping plate 183, then puts one end of the steel pipe into the frame 181, and then rotates the clamping rod 182 in the opposite direction. Because the clamping rod 182 and the frame 181 are threadedly installed, the two clamping rods 182 move relative to each other, and finally drive the two clamping plates 183 to clamp and fix the steel pipe. At this time, the moving seat 16 can be moved on the guide rail 15. The moving seat 16 can move linearly on the guide rail 15, so as to adjust the distance between the clamping assembly 18 and the support plate 12, which provides convenience for the user to put in the steel pipe. Finally, the stepper motor 17 rotates to drive the steel pipe to rotate for grinding. The moving seat 16 can be locked and fixed according to actual conditions during the movement process. Thereby ensuring the stability of steel pipe processing and providing convenience for users' work and use, the steel pipe will be sleeved on all the support plates 12. After the steel pipe is sleeved on all the support plates 12, as the steel pipe moves, all the support plates 12 will be squeezed, and then drive the slider 11 to slide into the interior of the sliding groove 10, and then compress the spring 13 until the steel pipe cannot move. At this time, all the support plates 12 are tightly attached to the inner wall of the steel pipe under the action of the spring 13, which can achieve a better grinding effect and provide convenience for users' work and use. Then start the stepper motor 2 17 to drive the clamping assembly 18 to rotate, and then the steel pipe will follow the rotation, and also start the stepper motor 1 7 to drive the gear 8 to rotate, the gear 8 will drive the gear ring 9 to rotate, and under the drive of the gear ring 9, the lower end The head 3 will also rotate with it, and under the action of the fixing part 4 and the roller 5, the end head 3 can rotate on the movable frame 2, wherein the fixing part 4 can provide support for the rotation of the end head 3, and the roller 5 can ensure the flexibility and smoothness of the end head 3 when rotating. At this point, the grinding assembly composed of the slider 11, the support plate 12 and the spring 13 can rotate and work. It should be noted that at this time, the grinding assembly is located inside the steel pipe, and all the support plates 12 are attached to the inner wall of the steel pipe, and the rotation direction of the grinding assembly is opposite to that of the stepper motor 2 17, thereby improving the grinding efficiency of the steel pipe, and then operate the adjustment assembly 14 to move the grinding block 19 to fit the surface of the steel pipe, and then when the steel pipe rotates, the grinding block 19 will also grind the surface of the steel pipe. Among them, the adjusting component 14 is used to adjust the grinding position of the grinding block 19. Before work, the adjusting screw 142 is rotated, and then the adjusting screw 142 will drive the adjusting block 143 to slide in the fixed seat 141, and the grinding block 19 installed on the adjusting block 143 will also move and adjust in the direction of the support plate 12, and finally fit on the outer wall of the steel pipe, so as to grind the outer wall of the steel pipe. In this way, it is convenient for users to place steel pipes and can also meet the grinding processing of steel pipes of different thicknesses, providing convenience for users' work. Then the user can hold the end rod 21 and push the installation rod 20 to move in the direction of the steel pipe, and the installation rod 20 will push the moving frame 2 to move, so that the grinding assembly will move in the steel pipe until the grinding assembly moves from one end of the steel pipe to the other end.In this way, the grinding process of the inner wall of the steel pipe is completed. In order to ensure the quality of grinding, the operation can be repeated several times to provide convenience for the user's work. Among them, the end rod 21 is used as a pushing handle. When working, the user can push the mobile frame 2 through the end rod 21 to control the grinding position of the mobile support plate 12, expand the grinding area of the inner wall of the steel pipe, and improve the grinding efficiency of the steel pipe. The installation rod 20 is used to extend the length of the mobile frame 2, so as to provide convenience for the user's work. With the rotation of the steel pipe, after the grinding work is completed, the grinding assembly is moved out of the interior of the steel pipe by pulling the end rod 21, and then the mobile seat 16 is moved away from the frame 1, and then the clamping rod 182 is rotated to drive the clamping plate 183 to leave the steel pipe, and finally the steel pipe is removed. It should be noted that in order to improve the convenience of grinding work, the movement of the mobile seats 16 and 2 can be set to an automatic working mode according to actual work needs. This is a prior art and will not be explained in detail in the text.
