Description

Technical Field

[0001] This utility model relates to the field of grinding technology, specifically a grinding wheel correction support structure. Background Technology

[0002] Grinding wheels are an important tool for internal hole grinding. With their specific abrasive and shape design, they can efficiently process the internal holes of workpieces made of various materials. Grinding wheels are widely used in fields such as machinery manufacturing and aerospace. When used in conjunction with grinding machines, they play a key role in precision internal hole machining, effectively improving the efficiency and quality of internal hole machining.

[0003] The general steps for dressing grinding wheels include preparation, wheel positioning, group dressing, fine dressing, dressing effect inspection, cleaning and adjustment. When positioning the grinding wheel, it is necessary to support it first in order to perform installation and adjustment operations more accurately.

[0004] During machining, existing grinding wheels are subjected to radial cutting forces, vibration, and impact, which can cause the grinding wheel to deviate from the grinding wheel axis. This reduces the axiality between the grinding wheel and the grinding wheel axis, affecting the normal machining of the grinding wheel.

[0005] Therefore, a grinding wheel correction support structure is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A grinding wheel correction support structure of this utility model includes a processing box, a first motor fixedly connected to the side wall of the processing box; a rotating shaft fixedly connected to the output end of the first motor; the first motor and the rotating shaft are rotatably connected; a cylinder fixedly connected to the top of the rotating shaft; multiple insertion holes are opened on the side wall of the cylinder; a lead screw is provided inside the insertion hole; the lead screw is threadedly connected inside the insertion hole; a ball bearing is rotatably connected to the end of the lead screw; the ball bearing is rotatably connected inside the lead screw; a grinding wheel body is sleeved on the outside of the rotating shaft. By adding the ball bearing, the grinding wheel can be corrected from multiple directions, making subsequent grinding of the grinding wheel more convenient and reducing the vibration displacement of the grinding wheel during grinding. At the same time, adding the ball bearing reduces the direct contact between the grinding wheel and the lead screw, reducing the long-term contact between the lead screw and the grinding wheel, thus reducing the occurrence of scratches and damage on the surface of the grinding wheel.

[0008] Preferably, a condenser is fixedly connected to the top of the processing box; a cooling plate is fixedly connected to the output end of the condenser; the condenser and the cooling plate are arranged correspondingly; by adding a cooling plate, the high temperature generated by the dressing tool when dressing the grinding wheel can be reduced. If cooling is not performed, the temperature of the dressing tool will rise sharply, resulting in a decrease in its hardness, increased wear, and even local melting or cracking.

[0009] Preferably, an air pump is fixedly connected to the top of the processing box; an air blowing pipe is fixedly connected to the end of the air pump; by adding an air blowing pipe, the surface of the grinding wheel can be cleaned before it is processed, reducing the occurrence of dust adhering to the surface during correction, which affects the correction of the grinding wheel.

[0010] Preferably, a chip collection groove is fixedly connected to the bottom inner side of the processing box; a second sliding groove is provided inside the chip collection groove; a scraper is provided inside the second sliding groove; the scraper is slidably connected inside the second sliding groove; by adding a scraper, the chips generated when the grinding wheel is corrected can be processed, reducing the accumulation of chips inside the processing box. At the same time, adding a scraper can also increase the space utilization rate inside the chip collection groove.

[0011] Preferably, a water tank is fixedly connected to the outer wall of the processing box; a water outlet pipe is fixedly connected to the end of the water tank; a second motor is fixedly connected to the bottom of the processing box; and a cleaning bucket is fixedly connected to the output end of the second motor. By adding a water outlet pipe, the surface of the grinding wheel can be cleaned in time after the grinding wheel has been corrected, thereby increasing the forming effect of the grinding wheel and reducing the residue of processing debris and dust.

[0012] Preferably, an absorbent sponge is fixed to the inner wall of the cleaning bucket; the absorbent sponge and the cleaning bucket are correspondingly arranged; by adding an absorbent sponge, the contact area between the surface of the grinding wheel and the cleaning bucket can be reduced, thus reducing the long-term contact between the grinding wheel and the surface of the cleaning bucket, thereby preventing scratches and other damage from appearing on the surface of the grinding wheel.

[0013] The advantages of this utility model are:

[0014] 1. The grinding wheel correction support structure described in this utility model allows the grinding wheel to be corrected from multiple positions by adding a lead screw, making subsequent grinding of the grinding wheel more convenient and reducing vibration and displacement of the grinding wheel during grinding. At the same time, adding ball bearings reduces direct contact between the grinding wheel and the lead screw, and the ball bearings allow the grinding wheel to move slightly when clamped by the lead screw, enabling processing of the grinding wheel in different positions.

[0015] 2. The grinding wheel dressing support structure described in this utility model can reduce the high temperature generated by the dressing tool when dressing the grinding wheel by adding cooling plates.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a grinding wheel correction support structure includes a processing box 1. A first motor 11 is fixedly connected to the side wall of the processing box 1. A rotating shaft 12 is fixedly connected to the output end of the first motor 11. The first motor 11 and the rotating shaft 12 are rotatably connected. A cylinder 13 is fixedly connected to the top of the rotating shaft 12. A plurality of insertion holes 14 are opened on the side wall of the cylinder 13. A lead screw 15 is provided inside the insertion hole 14. The lead screw 15 is threaded inside the insertion hole 14. A ball bearing 16 is rotatably connected to the end of the lead screw 15. The ball 16 is rotatably connected inside the lead screw 15; a grinding wheel body 17 is sleeved on the outside of the rotating shaft 12; the grinding wheel is placed inside the cylinder 13, which can be done manually. After placement, the lead screw 15 can be taken out and then inserted into the insertion hole 14. Since the lead screw 15 is slidably connected inside the insertion hole 14, it can be rotated. As the lead screw 15 rotates inside the insertion hole 14, the ball 16 at the top of the lead screw 15 will be pushed and will begin to rotate. At this time, the ball bearing 16 will contact the grinding wheel. Then, the remaining two lead screws 15 can be rotated to press the remaining two ball bearings 16 together against the grinding wheel. After that, the lead screws 15 are stopped. At this time, the grinding wheel will be clamped and fixed by multiple lead screws 15. After the fixing is completed, the grinding wheel can be corrected. If it is necessary to adjust the correction angle of the grinding wheel, the first motor 11 can be started. Then, the first motor 11 will drive the rotating shaft 12 to start rotating. The cylinder 13 at the top of the rotating shaft 12 will also be driven and clamped by the ball bearings 16. The grinding wheel will also be driven to rotate at this time. After rotating the grinding wheel to the appropriate machining angle, the first motor 11 can be stopped. By adding the lead screw 15, the grinding wheel can be corrected from multiple positions, which makes it easier to grind the grinding wheel later and reduces the vibration displacement of the grinding wheel during grinding. At the same time, adding the ball bearings 16 can reduce the direct contact between the grinding wheel and the lead screw 15, which can prevent scratches and damage to the surface of the grinding wheel.

[0026] like Figures 1 to 3 As shown, a condenser 21 is fixedly connected to the top of the processing box 1; a cooling plate 2 is fixedly connected to the output end of the condenser 21; the condenser 21 and the cooling plate 2 are arranged correspondingly; when the condenser 21 is started, the compressor compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant, and then this high-temperature, high-pressure gaseous refrigerant flows into the condenser 21, so the cooling plate 2 connected to the end of the condenser 21 is also cooled; by adding the cooling plate 2, the high temperature generated when the dressing tool is dressing the grinding wheel can be reduced. If cooling is not performed, the temperature of the dressing tool will rise sharply, resulting in a decrease in its hardness, increased wear, and even local melting or cracking.

[0027] like Figures 1 to 3 As shown, an air pump 31 is fixedly connected to the top of the processing box 1; an air blowing pipe 3 is fixedly connected to the end of the air pump 31; after the grinding wheel is supported from the inside by the ball bearing 16, the air pump 31 can be started before correction, and then the air pump 31 will inject air into the air blowing pipe 3. At this time, the air blowing pipe 3 will blow air onto the surface of the grinding wheel; by adding the air blowing pipe 3, the surface of the grinding wheel can be cleaned before it is processed, reducing the occurrence of dust adhering to the surface during correction, which affects the correction of the grinding wheel.

[0028] like Figures 1 to 3 As shown, a chip collection groove 41 is fixedly connected to the bottom inner side of the processing box 1; a second sliding groove 42 is provided inside the chip collection groove 41; a scraper 4 is provided inside the second sliding groove 42; the scraper 4 is slidably connected inside the second sliding groove 42; when correcting the grinding wheel, a cutting method is usually used, and the grinding wheel will produce chips during processing. When the chips fall, they will first fall into the chip collection groove 41. Then the scraper 4 can slide, and the scraper 4 will move inside the second sliding groove 42. The scraper 4 can collect and recycle the dust and chips generated during the correction of the grinding wheel; by adding the scraper 4, the chips generated during the correction of the grinding wheel can be processed, reducing the accumulation of chips inside the processing box 1. At the same time, adding the scraper 4 can also increase the space utilization rate inside the chip collection groove 41.

[0029] like Figures 2 to 4 As shown, a water tank 51 is fixedly connected to the outer wall of the processing box 1; a water outlet pipe 5 is fixedly connected to the end of the water tank 51; a second motor 52 is fixedly connected to the bottom of the processing box 1; a cleaning bucket 53 is fixedly connected to the output end of the second motor 52; after the grinding wheel is corrected, water can be injected into the water tank 51, and then the water outlet pipe 5 will spray water into the cleaning bucket 53. After spraying water, the grinding wheel can be placed into the cleaning bucket 53, and the second motor 52 will be started. The second motor 52 will drive the cleaning bucket 53 to rotate, and the grinding wheel will be cleaned. By adding the water outlet pipe 5, the surface of the grinding wheel can be cleaned in time after it is corrected, which increases the forming effect of the grinding wheel and reduces the residue of processing debris and dust.

[0030] like Figure 5As shown, an absorbent sponge 6 is fixed to the inner wall of the cleaning bucket 53; the absorbent sponge 6 and the cleaning bucket 53 are correspondingly arranged; when the cleaning bucket 53 rotates the grinding wheel, the absorbent sponge 6 will preferentially contact the grinding wheel, increasing the contact area between the absorbent sponge 6 and the grinding wheel; by increasing the absorbent sponge 6, the contact area between the surface of the grinding wheel and the cleaning bucket 53 can be reduced, reducing the grinding wheel's prolonged contact with the surface of the cleaning bucket 53, thereby preventing scratches and other damage to the surface of the grinding wheel.

[0031] Working principle: The grinding wheel is placed inside the cylinder 13, which can be done manually. After placement, the lead screw 15 can be removed and then inserted into the insertion hole 14. Since the lead screw 15 is slidably connected inside the insertion hole 14, it can be rotated. As the lead screw 15 rotates inside the insertion hole 14, the ball bearing 16 at the top of the lead screw 15 is pushed and begins to rotate. When the ball bearing 16 rotates, it contacts the grinding wheel. Then, the remaining two lead screws 15 can be rotated, causing the remaining two ball bearings 16 to contact and press against the grinding wheel. Afterwards, stop the lead screw 15. At this time, the grinding wheel will be clamped and fixed by multiple lead screws 15. After the fixing is completed, the grinding wheel can be corrected. If it is necessary to adjust the correction angle of the grinding wheel, the first motor 11 can be started. The first motor 11 will then drive the rotating shaft 12 to start rotating. The cylinder 13 at the top of the rotating shaft 12 will also be driven, and the grinding wheel clamped by the ball bearings 16 will also be driven to rotate. After the grinding wheel is rotated to the appropriate machining angle, the first motor 11 can be stopped. Then, start the condenser 21. The compressor will then compress the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gas. The refrigerant is in a gaseous state, and then this high-temperature, high-pressure gaseous refrigerant flows into the condenser 21, so that the cooling fins 2 connected to the end of the condenser 21 will also be cooled. After the grinding wheel is supported from the inside by the ball bearings 16, the air pump 31 can be started before correction. Then the air pump 31 will inject air into the air blowing pipe 3. At this time, the air blowing pipe 3 will blow air onto the surface of the grinding wheel. When correcting the grinding wheel, a cutting method is usually used. At this time, the grinding wheel will be processed and the chips will fall off. When the chips fall off, they will first fall into the chip collection groove 41. Then the scraper 4 can be slid. The scraper 4 will slide in the second sliding groove 4. 2. The internal displacement is achieved by the scraper 4, which can collect and recycle the dust and debris generated during the grinding wheel correction. After the grinding wheel is corrected, water can be added to the water tank 51, and then the water outlet pipe 5 will spray water into the cleaning bucket 53. After spraying water, the grinding wheel can be placed into the cleaning bucket 53, and the second motor 52 is started. The second motor 52 will drive the cleaning bucket 53 to rotate, and the grinding wheel will be cleaned. When the cleaning bucket 53 rotates the grinding wheel, the water-absorbing sponge 6 will first contact the grinding wheel, increasing the contact area between the water-absorbing sponge 6 and the grinding wheel.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
