Description

Technical Field

[0001] The invention relates to the technical field of spring processing equipment, in particular to a portable spring processing and grinding device. Background Art

[0002] As an important mechanical component, springs play a vital role in various industrial fields. They are widely used in many industries such as automobiles, electronic equipment, household appliances, medical equipment, etc. to absorb shock, store energy, control movement, etc. The processing quality of springs directly affects their performance and service life. In order to ensure the verticality and stability of the springs, the top and bottom of the springs usually need to be ground flat during the processing of the springs, so a grinding device is needed.

[0003] According to the search, the Chinese patent document, announcement number: CN118181021A, discloses a portable spring processing and grinding device. By clamping the spring in the fixed cover, pressing the spring through the pressure rod, and grinding the end face of the spring in the rotating cylinder, the operation is simpler and more portable than the grinding method of a handheld grinder. At the same time, the protective cover and the rotating cylinder can shield the splashes generated during the grinding process, reducing safety hazards.

[0004] However, in actual use, the portable grinding device can only be used for springs of a certain thickness because the thickness of the rotating cylinder is constant. Once the diameter of the spring is smaller than the inner diameter of the rotating cylinder, it is difficult to maintain the verticality of the spring by manually pressing the fixed cover to press the spring during the grinding process, which causes deviation after the spring is finished grinding. Therefore, further innovative improvements are needed. Summary of the invention

[0034] Specifically, three straight grooves 52 are opened circumferentially around the axis of the circular support plate 51, one end of the adjusting rod 511 is rotatably connected to the circular support plate 51, and the other end of the adjusting rod 511 is fixedly connected to the rotating wheel 516, and three slide seats 59 are arranged on the end surface of the circular plate 510 in an array around its axial direction. The advantage is that in the initial state, the gap between the three clamping plates 57 is maximized. When the spring to be polished is placed between the three clamping plates 57, the adjusting rod 511 can be driven to rotate by manually rotating the rotating wheel 516. The adjusting rod 511 forces the circular plate 510 to move, and the circular plate 510 drives the slide seat 2 59 to move.

The overall structure can clamp springs of various thicknesses, and then position the springs when polishing, thereby improving the applicability of the entire polishing device.

[0035] Specifically, two fixing screws 54 are inserted into the interior of the slide seat 55, and two hollow shafts 53 are slidably connected in the straight groove 52. The hollow shaft 53 has an outer shaft and an inner shaft, and the outer shaft and the inner shaft are rotatably connected. The advantage is that when adjusting the spacing between the three clamping plates 57, since the outer shaft of the hollow shaft 53 is rotatably connected to the inner shaft, and the fixing screw 54 is inserted into the interior of the inner shaft, the outer shaft of the hollow shaft 53 can slide in the straight groove 52, which is conducive to reducing friction resistance, so that when adjusting the spacing between the three clamping plates 57, the resistance is small and the adjustment is easy.

[0036] Specifically, the limit plate 513 has three connection ends, and the three connection ends are all provided with screw holes to be connected with the screw rod of the knob 514, and the outer surface of the fixing block 515 is penetrated with a round hole for the knob 514 to pass through. The advantage is that when the spring is placed between the three clamping plates 57, the limit plate 513 supports the bottom of the spring, and after loosening the three sets of knobs 514, the fixing block 515 is no longer tightly attached to the outer surface of the clamping plate 57, so that the height position of the limit plate 513 can be adjusted according to the height of the spring, and then the knob 514 is re-tightened to make the fixing block 515 fit again on the outer surface of the clamping plate 57, so as to achieve the purpose of fixing the limit plate 513; in this way, during the process of grinding the spring, the limit plate 513 can support the spring, and cooperate with the three clamping plates 57 to further fix the spring, and the position of the limit plate 513 needs to make the top of the spring extend from the top of the three clamping plates 57, so as to facilitate the grinding of the top of the spring.

[0037] Specifically, the outer surface of the clamping plate 57 is provided with a plurality of slots 9 at equal intervals, and the fixing block 515 includes a plurality of equally spaced fixing wires arranged on the inner side. The advantage is that by providing a plurality of slots 9 on the outer surface of the clamping plate 57 to cooperate with the fixing wires on the inner side of the fixing block 515, the fixing block 515 can be firmly clamped on the outer surface of the clamping plate 57 by the knob 514, thereby fixing the limit plate 513.

[0038] Specifically, the inner thread of the slider 4 is connected to the screw rod 10, the bottom end of the screw rod 10 is fixedly connected to the worm wheel 11, the worm wheel 11 is connected to the worm 12, the outer surface of the worm 12 is connected to the support plate 2 at the positions near the two ends, and one end of the worm 12 is fixedly connected to the crank 13. The advantage is that after the spring is fixed by the positioning assembly 5, the crank 13 is manually turned to drive the worm 12 to rotate, the worm 12 drives the worm wheel 11 to rotate, and the worm wheel 11 drives the screw rod 10 to rotate. Since the slider 4 is limited by the guide rail 3, the screw rod 10 can drive the slider 4 to rise and fall after rotating. When the slider 4 rises, it drives the circular support plate 51 to rise, and then drives the entire positioning assembly 5 and the spring to be polished to rise. By starting the motor 7, the grinding wheel 8 is driven to rotate at a high speed, so that as the spring rises, it can contact the lower surface of the grinding wheel 8, and then the top of the spring is polished. After the top of the spring is polished, the positions of the top and bottom of the spring are exchanged to realize the polishing of the bottom.

[0039] Specifically, a rectangular through slot 14 is provided on one side of the guide rail 3, and a scale mark 15 is engraved on the side of the guide rail 3 where the rectangular through slot 14 is provided. A pointer block 16 is slidably connected in the rectangular through slot 14, and the pointer block 16 is connected to the slider 4 through a bolt. The advantage is that when the slider 4 moves in the guide rail 3, the pointer block 16 can be driven to move, and the pointer block 16 slides under the limit of the rectangular through slot 14. By setting the scale mark 15 and cooperating with the pointer block 16, the specific height of the slider 4 can be controlled, so that the rising height of the spring can be controlled, and then the polishing degree of the spring can be controlled.

[0040] Specifically, a handle 17 is welded on the outer surface of the guide rail 3, four foot pads are arranged on the bottom surface of the base 1, and a dust cover 18 is installed on the lower surface of the top plate 6 by screws. The advantages are that the handle 17 is convenient for carrying the entire grinding device, and the four foot pads are arranged to stably place the base 1. During the grinding process, the grinding wheel 8 is located in the dust cover 18, so that the debris can be prevented from splashing during the grinding process.

[0041] Specifically, a dust suction pipe 19 is connected to the outer surface of the dust cover 18 , and one end of the dust suction pipe 19 is connected to the dust suction assembly 20 .

[0042] Specifically, the dust suction assembly 20 includes a top cover 201 threadedly connected to the dust suction pipe 19, the lower end surface of the top cover 201 is connected to the volute 202 by screws, the bottom end of the volute 202 is connected to the L-shaped bracket 203 by screws, the inner side of the L-shaped bracket 203 is installed with a motor 204, the output shaft of the motor 204 is connected to the wind wheel 205, and the outer surface of the volute 202 is fixedly connected to the dust outlet pipe 206. The advantage is that during the spring grinding process, the wind wheel 205 can be driven to rotate by starting the motor 204, and the wind wheel 205 generates negative pressure in the volute 202, thereby generating negative pressure in the dust suction pipe 19, and one end of the dust suction pipe 19 is connected to the dust cover 18, so the debris and dust generated during the spring grinding process will be sucked into the dust suction pipe 19, and then enter the volute 202, and finally discharged from the dust outlet pipe 206. A cloth bag is connected to the dust outlet pipe 206, so that the debris and dust can be collected into the cloth bag, and because the filter cotton 207 is provided to prevent the debris and dust from entering the wind wheel 205, the overall structure can realize the collection of debris and dust during the spring grinding process to avoid affecting the on-site working environment.

[0043] When in use, first, when grinding the spring for the first time, put a spring to be ground between the three clamping plates 57, and manually rotate the rotating wheel 516 to drive the adjusting rod 511 to rotate, and the adjusting rod 511 forces the circular plate 510 to move, and the circular plate 510 drives the second slide 59 to move, and the second slide 59 drives the connecting rod 58, and the connecting rod 58 drives the first slide 55, and the first slide 55 cooperates with the fixing screw 54 to drive the bottom block 56 to slide in the straight groove 52, so that the spacing between the three clamping plates 57 can be adjusted synchronously, so that the three clamping plates 57 can clamp the spring to be ground. The spring is worn; then, after loosening the three sets of knobs 514, the fixing block 515 is no longer tightly attached to the outer surface of the clamping plate 57, and then the height position of the limit plate 513 is adjusted according to the height of the spring, and then the knob 514 is tightened again to make the fixing block 515 fit again to the outer surface of the clamping plate 57, so as to achieve the purpose of fixing the limit plate 513, so that the limit plate 513 can support the spring, and ensure that the top of the spring protrudes a little from the top of the three clamping plates 57; then, the worm 12 is driven to rotate by manually turning the crank 13, and the worm 12 drives The worm gear 11 rotates, and the worm gear 11 drives the lead screw 10 to rotate. After the lead screw 10 rotates, it can drive the slider 4 to rise and fall. When the slider 4 rises, it drives the circular support plate 51 to rise, and then drives the entire positioning assembly 5 and the spring to be polished to rise. By starting the motor 7, the grinding wheel 8 is driven to rotate at a high speed. In this way, as the spring rises, it can contact the lower surface of the grinding wheel 8, and then the top of the spring is polished. By observing the position of the pointer block 16 on the scale mark 15, the height of the spring rise can be controlled, and then the degree of spring polishing can be controlled. After the spring top is polished, it is replaced. Its top and bottom positions, and then starts to grind the bottom end of the spring; during the grinding process, the wind wheel 205 can be driven to rotate by starting the second motor 204, and the wind wheel 205 causes negative pressure to be generated in the volute 202, thereby causing negative pressure to be generated in the dust suction pipe 19, and one end of the dust suction pipe 19 is connected to the dust cover 18, so the debris and dust generated in the process of grinding the spring will be sucked into the dust suction pipe 19, and then enter the volute 202, and finally discharged from the dust outlet pipe 206, and a cloth bag is connected to the dust outlet pipe 206, so that the debris and dust can be collected in the cloth bag.
