[0019] The following is combined with Figure 1-4, the specific implementation methods of the utility model are described in detail. The implementation methods are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model. Obviously, the embodiments described in the utility model are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the utility model.

[0020] "One embodiment" or "some embodiments" described in this specification means that one or more embodiments of the present invention include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, in this specification, the terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized.

[0021] like Figures 1 to 4 As shown, a steel pipe processing and polishing device provided by an embodiment of the utility model comprises a polishing machine body 1, a control seat 2 and a guide wheel 3. The control seat 2 and the guide wheel 3 are both arranged on the top of the polishing machine body 1, the control seat 2 and the guide wheel 3 are arranged side by side, and the steel pipe bracket is installed between the control seat 2 and the guide wheel 3, and a notch is opened on the steel pipe bracket. A mounting column 4 is arranged on the front side of the control seat 2, and the mounting column 4 is arranged opposite to the guide wheel 3. A polishing wheel 5 is detachably mounted on the mounting column 4.

[0022] It should be noted that when grinding the steel pipe, the steel pipe is placed on a steel pipe support, the polishing wheel 5 performs rotational grinding on the steel pipe, and the guide wheel 3 serves as an auxiliary device to support the steel pipe and prevent it from falling out.

[0023] The inner cavity of the polishing wheel 5 is fixedly connected to the hub 6, the mounting column 4 is cylindrical, and an installation groove 7 is opened along the axial direction. The front end of the installation groove 7 is a circular fixing plate, and the control part 8 is inserted into the installation groove 7 from the fixing plate. The front part of the control part 8 is exposed outside the installation groove 7, that is, exposed outside the circular fixing plate. A limiting device 9 is also installed in the inner cavity of the plate installation groove 7.

[0024] The limiting device 9 includes a plurality of limiting blocks 901, for example Figure 4 The invention comprises four limit blocks 901 in the slide frame 10, a slide frame 10 having the same number of slide slots as the limit blocks 901, and a plurality of moving blocks 902 respectively connected with the limit blocks 901 and the slide frame 10. A spring 903 is installed in each slide slot, the upper part of each moving block 902 is fixedly connected with the inner surface of the corresponding limit block 901, and the lower part of the moving block 902 is inserted into the slide slot and connected with the corresponding spring 903.

[0025] It should also be noted that the outer surface of the limit block 901 is in an arc shape, and the plurality of limit blocks 901 are arranged at a predetermined distance on the circumference, and a lever 11 is provided on the inner side of each movable block 902 .

[0026] The mounting column 4 is provided with through holes having the same number as the limiting blocks 901 , and the through holes are connected to the installation slot 7 . The limiting blocks 901 can extend from or retract into the installation slot 7 in the radial direction.

[0027] refer to Figure 3 The fixed part includes a handle part, a rotating disc 13, a connecting rod, and a rotating block 12. The rotating block 12 is installed at the rear of the connecting rod and is provided with the same number of rotating rods as the lever 11. Each rotating rod is fixedly connected to a lever 11. The handle part is fixed to the head of the connecting rod. Two rotating discs 13 are installed on the lever 11 and close to the handle part. One rotating disc 13 contacts the inner side of the circular fixed plate, and the other rotating disc 13 contacts the outer side of the circular fixed plate. The handle part is arranged outside the circular fixed plate. The coordinated use of the two rotating discs 13 has a limiting effect on the horizontal position of the control block 8. When the handle part is pulled, the control block 8 cannot be separated from the working position due to the existence of the rotating discs 13. In addition, when the control part 8 is released, the restoring force generated by the spring 903 restoring its shape will drive the limit block 901 to extend out of the through hole and get stuck into the inner cavity of the limit groove 14. The coordinated use of the limit block 901 and the limit groove 14 has a limiting effect on the position of the polishing wheel 5.

[0028] refer to Figure 2 The inner cavity of the wheel hub 6 is provided with a plurality of limiting grooves 14 for use with the limiting blocks 901 , and the limiting blocks 901 can be embedded in the limiting grooves 14 . In this embodiment, the number of the limiting grooves 14 is 4 and they are evenly distributed on the circumference of the inner cavity of the wheel hub 6 .

[0029] In order to better understand the technical solution of the utility model, the following uses the replacement of the polishing wheel used in the steel pipe polishing machine as an example to illustrate the use method of the utility model:

[0030] 1) First, the operator removes the polishing wheel 5 to be replaced, then sets the polishing wheel 5 and the hub 6 on the surface of the mounting column 4, and then rotates the control unit 8;

[0031] 2) When the control part 8 rotates, it will drive the rotating disk 13 to rotate along the circular fixed plate of the mounting column 4. When the control part 8 rotates, it will drive the rotating block 12 to rotate. The rotating block 12 drives the lever 11 to rotate. The lever 11 drives the moving block 902 to move in the slide slot. When the moving block 902 moves, the force generated causes the spring 903 to undergo elastic deformation. When the moving block 902 moves, it can drive the limit block 901 to move radially inward in the through hole.

[0032] 3) When the limit block 901 is completely moved into the inner cavity of the device groove 7, the polishing wheel 5 and the hub 6 continue to move toward the rear along the surface of the mounting column 4, and the control part 8 is released. The restoring force generated by the spring 903 restoring its shape will drive the limit block 901 to extend out of the through hole and get stuck into the inner cavity of the limit groove 14. The coordinated use of the limit block 901 and the limit groove 14 has a limiting effect on the position of the polishing wheel 5. At this time, the polishing wheel 5 used in the steel pipe polishing machine can be replaced conveniently and stably, and the method for removing the polishing wheel 5 is opposite to the above operation method.

[0033] The utility model solves the problem that when disassembling the existing steel pipe polishing machine, auxiliary tools are needed to disassemble multiple bolts or pins, which takes a long time and is not convenient enough. In addition, the torque of all bolts and pins needs to be controlled during installation. If the torque is uneven, it is easy to cause unstable installation.

[0034] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
