Technical Field
[0001] This utility model relates to the field of steel pipe cutting and grinding technology, and more specifically to a device for cutting and grinding the round tube frame of a folding bicycle. Background Technology
[0002] Folding bikes are bicycles that are easy to carry and store. They can be folded down to reduce their size when not in use. Like ordinary bicycles, their main structure is made of round steel tubes that are cut and welded. After the round steel tubes are cut, there will be some burrs on the cut surfaces, which need to be polished before subsequent processes can be carried out. Currently, workers often use round tube polishing machines to polish them.
[0003] In actual processing, the diameter of round steel pipes varies. When grinding round steel pipes of different diameters, it is necessary to change the fixture of the grinding machine to adapt to the different diameter round steel pipes. At present, most of the fixtures of grinding machines are fixed by screws. When changing them, the staff needs to repeatedly disassemble and assemble multiple screws, which is cumbersome and slow. Therefore, it is urgent to design a grinding device for the cutting edge of the round steel pipe frame of folding car to solve the above problems. Utility Model Content

[0021] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.
[0022] A grinding device for cutting the round tube frame of a folding bicycle includes a grinding machine body 1, a first mounting block 2, a second mounting block 3, and two clamping components 4 and four locking components 9. The first mounting block 2 is fixedly installed in the grinding machine body 1, the second mounting block 3 is slidably installed in the grinding machine body 1, the two clamping components 4 are respectively disposed in the first mounting block 2 and the second mounting block 3, and the four locking components 9 are respectively disposed in the two clamping components 4.
[0023] The clamping assembly 4 includes a clamp 401. The first mounting block 2 and the second mounting block 3 each have a mounting groove 5 on one side. The clamp 401 is slidably installed in the mounting groove 5. The locking assembly 9 includes a slider 901 and a locking block 902. The slider 901 is slidably installed in the clamp 401. The locking block 902 is fixedly installed on the outside of the slider 901 and is adapted to the clamp 401.
[0024] Specifically, the inner walls of the two mounting slots 5 each have two L-shaped slots 6, which are adapted to the locking block 902.
[0025] Specifically, the inner walls of both mounting slots 5 are provided with positioning slots 7, and the clamping assembly 4 also includes a positioning block 405. The positioning block 405 is fixedly installed on the outer wall of the clamp 401, and the positioning block 405 is adapted to the positioning slot 7.
[0026] In this embodiment, the positioning block 405 and the positioning groove 7 are provided to assist in positioning the insertion angle of the clamp 401 when it is inserted into the mounting groove 5.
[0027] Specifically, the inner walls at both ends of the two positioning grooves 7 are provided with limiting grooves 8, and the clamping assembly 4 also includes two limiting strips 406. The two limiting strips 406 are respectively fixedly installed at both ends of the positioning block 405, and the limiting strips 406 are adapted to the limiting grooves 8.
[0028] In this embodiment, the limiting groove 8 and the limiting strip 406 can be used to vertically limit the clamp 401 when it is in the mounting groove 5, so as to prevent the clamp 401 from sliding vertically.
[0029] Specifically, the outer wall of the fixture 401 has two arc-shaped grooves 402, and the slider 901 is slidably installed in the arc-shaped grooves 402.
[0030] Specifically, the locking assembly 9 also includes a spring 903, a slide bar 904, and a toggle switch 905. The spring 903 is fixedly installed between the slider 901 and the inner wall of the arc groove 402. The slide bar 904 is fixedly installed on one side of the slider 901.

[0033] Working principle: When it is necessary to replace the clamp 401, press and slide the two dials 905 to drive the two slide rods 904 to slide in the two slide grooves 403 respectively. The sliding of the two slide rods 904 will drive the two sliders 901 to slide in the two arc-shaped grooves 402 and compress the two springs 903. The sliding of the two sliders 901 will drive the two locking blocks 902 to slide in the two L-shaped grooves 6. When the locking blocks 902 slide to the right angle corner of the L-shaped groove 6, slide the clamp 401 outward. At this time, the two locking blocks 902 will not be blocked by the L-shaped groove 6, and the clamp 401 can be removed from the mounting groove 5.
