Description

Technical Field

[0001] This utility model relates to the field of stainless steel screw processing and grinding technology, and in particular to a grinding device for stainless steel screw processing. Background Technology

[0002] Stainless steel screws are corrosion-resistant fasteners made primarily of austenitic stainless steel. They achieve corrosion protection by reacting chromium with oxygen to form a chromium oxide protective layer. They are widely used in medical devices, shipbuilding, chemical equipment, construction, energy, and other fields.

[0003] The materials are divided into non-magnetic / weakly magnetic austenitic types and magnetic martensitic / ferritic types; magnetism is not used as a quality criterion. The products are manufactured using wire stacking and thread rolling processes, possessing acid, alkali, and high-temperature resistance. Physical properties include high resistivity, low-temperature toughness, and low thermal conductivity. Some models enhance their anti-loosening ability by adding engineering resins or anti-loosening adhesives. To improve durability, the new design employs a multi-layer composite structure.

[0004] In the present technology, stainless steel screws need to be polished after production to remove burrs, rust and other impurities from the surface. The traditional method is to manually hold the screw and make contact with the polishing disc to complete the polishing. Holding the screw requires force to fix it, which causes fatigue to the operator's hands and causes sparks and debris to fly, affecting the safety of operation and making it impossible to achieve automatic polishing.

[0026] Reference Figure 1-4This utility model discloses a grinding device for processing stainless steel screws, comprising: a grinding box 1, a rear fixing frame 6 fixedly connected to the upper rear side of the grinding box 1, a drive motor 7 fixedly connected to the middle of the top of the rear fixing frame 6, the drive motor 7 drives the turntable 8 to rotate, which cooperates with the rotation rod 9 to realize the up-and-down reciprocating motion of the top plate 5 and the sliding rod 4 as a whole. The drive end of the drive motor 7 is fixedly connected to the turntable 8, the front end of the turntable 8 is rotatably connected to the rotation rod 9, the bottom end of the rotation rod 9 is rotatably connected to the top plate 5, and the bottom ends of the top plate 5 are fixedly connected to the sliding rod 4. After the moving rod 4 reciprocates, it can drive the clamping slider 15 at the bottom to move up and down reciprocally. The bottom of the sliding rod 4 is fixedly connected to the clamping slider 15. The inner side wall of the clamping slider 15 abuts against the polishing paper 13. The polishing paper 13 rubs up and down on the surface of the stainless steel screw 10 to polish and clean the rust or burrs on the surface. The polishing paper 13 is sleeved on the outside of the stainless steel screw 10. At this time, when the support sleeve rod 3 is pressed closer to the stainless steel screw 10, it is fixed firmly. The bottom of the polishing box 1 is inserted into the collection box 2. The polishing debris will fall into the collection box 2 for unified treatment.

[0027] The grinding box 1 has two fixed upper sides inside, and two fixed sides inside the middle, and two fixed sides, and two sliding rods 14 inside the middle, respectively. The middle parts of the second sliding rods 14 and the first sliding rods 11 are slidably engaged with the clamping sliders 15. There are four clamping sliders 15. The inside of the clamping sliders 15 is rotatably connected to an adjusting screw 16. Rotating the adjusting screw 16 moves the clamping side plate 17 threadedly, which can replace the grinding paper 13. The middle part of the adjusting screw 16 is threadedly connected to the clamping side plate 17. The clamping side plate 17 and one end of the inner wall of the clamping sliders 15 clamp the grinding paper 13. The middle rear side of the grinding box 1 is fixedly connected to a fixing sleeve 19. The fixing sleeve 19 is filled with rubber blocks 18, and stainless steel screws are inserted into the rubber blocks 18. The stainless steel screw 10 has a support sleeve 3 fitted at one end. By fitting the stainless steel screw 10 inside the support sleeve 3, the stainless steel screw 10 will rotate with the support sleeve 3 when the support sleeve 3 is released, allowing for adjustment of the grinding position. Both the support sleeve 3 and the stainless steel screw 10 are inserted into the grinding box 1. The support sleeve 3 and the grinding box 1 are interlocked. A support spring 12 is fitted on the bottom of the first slide rod 11. On the other side of the grinding paper 13, a support spring 12 is fitted on the bottom of the first slide rod 11, increasing the reset function of the overall structure of the clamping slider 15 in the middle of the first slide rod 11. Pressing rods 20 are inserted on both sides of the top of the grinding box 1. The pressing rods 20 can press down the clamping slider 15 to prevent the arc of the grinding paper 13 from affecting the smooth insertion of the stainless steel screw 10.

[0028] Working principle: In use, the stainless steel screw 10 is first fitted inside the support sleeve 3, and both the support sleeve 3 and the stainless steel screw 10 are inserted into the grinding box 1. One end of the stainless steel screw 10 engages with the internal rubber block 18 of the fixing sleeve 19. Then, the grinding paper 13 is fitted over the outside of the stainless steel screw 10. When the support sleeve 3 is pressed closer to the stainless steel screw 10, it is firmly fixed. When the support sleeve 3 is loosened, the stainless steel screw 10 is also loosened. When grinding of the stainless steel screw 10 is required, the drive motor 7 drives the turntable 8 to rotate, which, in conjunction with the rotating rod 9, enables the top plate 5 and the sliding rod 4 to reciprocate up and down. When the sliding rod 4 reciprocates, it drives the clamping slider 15 at the bottom to move upwards. The reciprocating motion of raising and lowering allows the polishing paper 13 to rub against the surface of the stainless steel screw 10, polishing and cleaning the rust or burrs on the surface. On the other side of the polishing paper 13, a support spring 12 is sleeved at the bottom of the first slide rod 11, which increases the reset function of the overall structure of the clamping slider 15 in the middle of the first slide rod 11. When polishing a fixed position is required, the support sleeve 3 is pressed, and when the support sleeve 3 is released, the stainless steel screw 10 will rotate in cooperation with the support sleeve 3, which can adjust the polishing position. When the polishing paper 13 needs to be replaced, the structure of the polishing box 1 can be disassembled, and the adjustment screw 16 can be rotated to move the threaded side plate 17, so that the polishing paper 13 can be replaced. The polishing debris will fall into the collection box 2 for unified treatment.
