DETAILED DESCRIPTION

[0021] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0022] See also Figures 1 to 4 The utility model provides a technical solution of an adjustable circular arc grinder: an adjustable circular arc grinder, comprising a bearing plate 1 and a steel pipe 2. A mounting rod 3 is sleeved inside the steel pipe 2. A stabilizing assembly 7 is arranged on the top of the bearing plate 1. A motor 4 is fixedly connected to the end surface of the mounting rod 3. The motor 4 is fixed to the top of the bearing plate 1. A storage box 8 is arranged at the bottom of the steel pipe 2. A slider is fixedly connected to the bottom of the storage box 8. A slide groove for sliding the slider is provided at the top of the bearing plate 1, which plays the role of limiting the installation of the storage box 8, so that after the storage box 8 is installed at the bottom of the steel pipe 2, the top of the sanding plate 103 fits the outer wall of the steel pipe 2;

[0023] Specifically, the storage box 8 is provided with a grinding component 10, which includes a sanding plate 103. The bottom of the sanding plate 103 is fixedly connected with a spring 101. The bottom end of the spring 101 is fixedly connected to the inner bottom wall of the storage box 8. A damper 102 is sleeved inside the spring 101. The two ends of the damper 102 are respectively fixedly connected to the sanding plate 103 and the storage box 8. When the steel pipe 2 rotates, the sanding plate 103 can keep the top end in contact with the steel pipe 2 through the action of the spring 101, so as to achieve the grinding of the steel pipe 2. During the grinding process, the spring 101 can provide a stable pressure to ensure that the contact between the top end of the sanding plate 103 and the steel pipe 2 always maintains an appropriate force, so that the arc surface of the steel pipe 2 can be effectively ground. At the same time, the damper 102 can reduce vibration and provide additional stability and control to ensure the stability and accuracy during the grinding process.

[0024] Furthermore, a cleaning brush 104 is fixedly connected to the top of the rear side of the storage box 8. The cleaning brush 104 contacts the steel pipe 2 and is used to clean the surface of the steel pipe 2 after grinding. The steel pipe 2 after grinding by the sand plate 103 continues to rotate and contact with the cleaning brush 104, which can be used to clean up the waste chips polished on the outer wall of the steel pipe 2. The cleaning brush 104 usually has bristles or rigid materials, which can effectively remove the waste chips and debris on the surface of the steel pipe 2. When the steel pipe 2 rotates, the cleaning brush 104 contacts the outer wall of the steel pipe 2, which can clean up the waste chips and dust generated after grinding, ensuring the smoothness and quality of the surface of the steel pipe 2. The cleaned waste chips fall into the storage box 8. In this way, the waste chips generated during the grinding process can be effectively removed, making the outer wall of the steel pipe 2 neater and smoother, and also conducive to the smooth progress of subsequent processes;

[0025] When the locking cam 73 is in the locked state, the locking cam 73 is in the locked state, and the locking cam 73 is in the locked state, so that the locking cam 73 can be locked to the locking cam 73 by the locking cam 73a.

[0026] Furthermore, a positioning rod 12 is fixedly connected to the rear side of the storage box 8, a vertical plate 14 is fixedly connected to the top of the load-bearing plate 1, and a positioning tube 13 is fixedly connected to the front side of the vertical plate 14. The material of the positioning tube 13 can be rubber, etc. The positioning rod 12 is clamped with the positioning tube 13. To ensure the stability of the storage box 8 after installation, a special positioning rod 12 is clamped with the positioning tube 13 to enhance the firmness.

[0027] The working principle and use process of the utility model are as follows: after the steel pipe 2 is sleeved on the outer wall of the erection rod 3, the T-shaped sliding rod 71 is moved to slide in the L-shaped sliding groove 72 so that the stabilizing plate 73 is opposite to the erection rod 3, and the stabilizing plate 73 is rotated and threadedly connected with the erection rod 3 to clamp the steel pipe 2 between the limit plate 5 and the stabilizing plate 73, and the motor 4 is started to drive the output end to drive the steel pipe 2 to rotate. At this time, the spring 101 is pressed and cooperated with the damper 102 to make the top of the sand plate 103 contact with the steel pipe 2. The contact can realize the grinding of the arc surface of the steel pipe 2. The steel pipe 2 after grinding by the sand plate 103 continues to rotate and contact with the cleaning brush 104, which can effectively remove the waste and debris on the surface of the steel pipe 2. The cleaned waste and debris fall into the storage box 8. After grinding contact, the stabilizing plate 73 is slid in the L-shaped slide groove 72 through the T-shaped sliding rod 71 and staggered with the erection rod 3. At this time, the erection rod 3 can be unobstructed to move the steel pipe 2 out, and then the storage box 8 can be pulled out to clean the waste and debris.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
