DETAILED DESCRIPTION

[0018] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0019] Example 1: A grinding machine with dustproof function, such as Figures 1-9 As shown, it includes: a double-side grinder 1, an outer tooth 2, a lower grinding disc 3, an upper grinding disc 4 and an inner tooth 5; a protective cover 1001 is provided on the double-side grinder 1; the upper grinding disc 4 is provided on the protective cover 1001; the outer tooth 2 is mounted on the double-side grinder 1 via a mounting post 2001; the inner tooth 5 is provided on the double-side grinder 1 via a rotating connecting post 5001; a rotating member 5002 is provided on the rotating connecting post 5001; and the lower grinding disc 3 is provided on the rotating member 5002; The fixing frame 101 is rotatably connected to the rotating member 5002, and the upper side of the fixing frame 101 is fixedly connected to the lower grinding disc 3; four drainage grooves 10101 are provided on the fixing frame 101; four first electric push rods 102 are bolted to the fixing frame 101; the telescopic ends of all the first electric push rods 102 are commonly bolted to a connecting plate 103; a plurality of leakage holes 10301 are provided on the connecting plate 103; The support frame 104 is connected to the support frame 104 through the connecting rod 10401. The support frame 104 consists of a connecting rod 10401, an arc block 10404 and a blocking block 10405. The diameter of the connecting rod 10401 is smaller than the diameter of the blocking block 10405. The lower grinding disc 3 is provided with the same number of drainage holes 3002 as the connecting rod 10401, and the diameter of the blocking block 10405 is the same as the diameter of the drainage holes 3002. The lower grinding disc 3 is provided with the same number of guide grooves 3001 as the arc blocks 10404. The lower grinding disc 3 is connected to a suction assembly.

[0020] In order to speed up the flow of lubricating fluid, each guide groove 3001 is configured to be higher in the middle and lower on both sides.

[0021] It also includes a water pipe 105; each arc block 10404 is provided with a water storage space 10402; each arc block 10404 is provided with a plurality of water spray troughs 10403, and the arc block 10404 is connected to the water storage space 10402 through the water spray troughs 10403; each water storage space 10402 is connected to a water pipe 105.

[0022] The suction assembly includes a mounting ring 201, a liquid suction frame 204 and a suction pump 205; the part close to the center of the upper grinding disc 4 is the inner part, and the part away from the center is the outer part, and a mounting ring 201 is fixedly connected to the outer and inner sides of the lower grinding disc 3; a liquid suction frame 204 is fixedly connected to the corresponding blocking blocks 10405; each mounting ring 201 is provided with the same number of suction pumps 205 as the liquid suction frames 204, and all the liquid suction frames 204 are connected to the corresponding suction pumps 205 through hoses.

[0023] It includes a second electric push rod 202 and a moving ring 203; five second electric push rods 202 are bolted to each mounting ring 201; the telescopic ends of all second electric push rods 202 are bolted to a moving ring 203; each moving ring 203 is provided with a plurality of liquid spray holes 20302; the second electric push rod 202 pushes the moving ring 203 to move upward, thereby pushing the limit gear 10 upward, and making it convenient for the liquid suction frame 204 to suck the lubricating liquid on the gap between the workpiece 11 and the limit gear 10.

[0024] It includes a main pipe 206; each mounting ring 201 is provided with the same number of main pipes 206 as the suction pumps 205, and each main pipe 206 is connected to the corresponding suction pump 205; each movable ring 203 is provided with the same number of liquid storage spaces 20301 as the main pipes 206, and each liquid storage space 20301 is connected to the corresponding main pipe 206 through several branch pipes 20601.

[0025] The working process of this grinding machine with dust protection function is as follows: It should be noted that: all the water pipes 105 are connected to a water pump; in the initial state of the support frame 104, the arc block 10404 and the blocking block 10405 on the support frame 104 are flush with the surface of the lower grinding disc 3.

[0026] During the grinding process of the workpiece 11, the existing double-sided grinder 1 usually continuously injects lubricating fluid to reduce the friction between the workpiece 11 and the grinding disc, avoid high temperature caused by excessive friction, and cause damage to the grinding disc. In addition, the lubricating fluid can also be used to cool down and reduce dust, and avoid flying debris generated by grinding. After the grinding is completed, due to excessive injection of lubricating fluid, the limit gear 10 and the workpiece 11 are tightly fitted to the grinding disc, making it difficult for workers to remove the limit gear 10 and the workpiece 11 from the grinding disc. In addition, after the grinding is completed, the lubricating fluid will carry debris generated during grinding. Therefore, after removing the limit gear 10 and the workpiece 11, the worker needs to rinse the grinding disc to avoid the debris on the grinding disc affecting the grinding accuracy of the next batch of workpieces 11. The worker's cleaning efficiency is low, which leads to reduced grinding efficiency.

[0027] First, a worker places the limit gears 10 one by one on the lower grinding disc 3. During the placement process, the teeth on the limit gears 10 need to mesh with the outer teeth 2 and the inner teeth 5 on the double-sided grinder 1. Then, the worker places the workpieces 11 one by one on the corresponding limit gears 10, so that the workpieces 11 are limited by the limit gears 10. The thickness of the workpieces 11 is thicker than that of the limit gears 10. After the workpieces 11 are placed, the worker starts the double-sided grinder 1, so that the upper grinding disc 4 is rotated to the top of the lower grinding disc 3, and then lowered so that the lower side of the upper grinding disc 4 contacts the upper side of the workpiece 11. Then, the limit gear 10 is driven to rotate by the inner teeth 5, and the lower grinding disc 3 is driven to rotate by the rotating member 5002. At the same time, the upper grinding disc 4 will also be driven to rotate by the driving member thereon. In order to improve the grinding effect, the rotation directions of the lower grinding disc 3 and the upper grinding disc 4 are opposite. During the grinding process, lubricating fluid will be injected into the workpiece 11 through the upper grinding disc 4 for lubrication, cooling and dust reduction.

[0028] After the workpiece 11 is ground, the double-sided grinder 1 will control the upper grinding disc 4 to separate from the workpiece 11, and then push the connecting plate 103 and the support frame 104 upwards through the first electric push rod 102, so as to separate the limit gear 10 and the workpiece 11 from the lower grinding disc 3. When the lower side of the blocking block 10405 on the support frame 104 is 3-5m away from the upper side of the lower grinding disc 3, the first electric push rod 102 will stop pushing. At this time, the lubricating fluid remaining on the lower grinding disc 3 will flow into the guide groove 3001 on the lower grinding disc 3, and then, under the guidance of the guide groove 3001 with the middle high and the two ends low, the lubricating fluid on the lower grinding disc 3 will flow into the guide groove 3001. The liquid flows through the drainage hole 3002, then passes through the drainage hole 3002 and falls onto the connecting plate 103, then passes through the leakage hole 10301 on the connecting plate 103, falls onto the fixed frame 101, and is finally discharged through the drainage groove 10101 on the fixed frame 101. The support frame 104 separates the limit gear 10 and the workpiece 11 from the lower grinding disk 3, which can prevent the lubricating liquid remaining in the space formed by the holes of some workpieces 11 and the lower grinding disk 3 from being unable to be discharged. At the same time, there is a distance between the lower side of the limit gear 10 and the workpiece 11 and the upper side of the lower grinding disk 3, which makes it more convenient for workers to separate the limit gear 10 and the workpiece 11.

[0029] After the limiting gear 10 and the workpiece 11 are removed, water is pumped to all the water pipes 105 through a water pump, so that the water is input into the water storage space 10402 on the corresponding support frame 104, and then sprayed out from the water spray trough 10403 on the support frame 104, thereby flushing the lubricating liquid and debris remaining on the lower grinding disc 3, thereby preventing the lubricating liquid carrying debris from affecting the grinding accuracy of the next batch of workpieces 11, and at the same time, improving the cleaning efficiency of the lower grinding disc 3. The flushing water will pass through the guide groove 3001, the drainage hole 3002 and the leakage hole 10301 in turn, and finally be discharged from the drainage groove 10101.

[0030] During the grinding process of the workpiece 11, the generated debris will be retained on the lower grinding disc 3. If the retained debris is not cleaned, the debris will gradually accumulate, thereby affecting the grinding accuracy of the workpiece 11. Therefore, during the grinding process of the workpiece 11, the suction pump 205 will suck the lubricating fluid and debris on the lower grinding disc 3 through the liquid suction frame 204. Considering that there is a gap between the workpiece 11 and the limit gear 10, the debris generated by the upper grinding disc 4 when grinding the workpiece 11 will flow down the grinding disc 3 along the four sides of the workpiece 11 driven by the lubricating fluid. The lubricating fluid in the gap between the workpiece 11 and the limiting gear 10 does not flow smoothly, which makes it difficult for the suction pump 205 to suck the lubricating fluid from the gap between the workpiece 11 and the limiting gear 10. Therefore, the second electric push rod 202 pushes the moving ring 203 upward to separate the limiting gear 10 from the lower grinding disc 3, so that the lubricating fluid between the workpiece 11 and the limiting gear 10 is not blocked by the limiting gear 10 and continues to flow to the surface of the lower grinding disc 3, thereby facilitating the suction by the suction pump 205.

[0031] It should be noted that: in order to avoid insufficient lubrication after the suction pump 205 sucks the lubricating liquid on the lower grinding disc 3, resulting in excessive friction, high temperature, and damage to the lower grinding disc 3, the upper grinding disc 4 and the workpiece 11, the suction pump 205 is provided with a filtering function, so that the filtered lubricating liquid can be pumped into the main pipe 206 through the suction pump 205, and then pumped into the liquid storage space 20301 on the movable ring 203 through the branch pipe 20601, and then sprayed out from the spray hole 20302 on the movable ring 203 to the lower grinding disc 3, thereby saving lubricating liquid.

[0032] According to the above workflow, we can know that the present invention has the following effects: After the workpiece 11 is ground, the connecting plate 103 and the support frame 104 are pushed upward by the first electric push rod 102, thereby separating the limit gear 10 and the workpiece 11 from the lower grinding disc 3. When the lower side of the blocking block 10405 on the support frame 104 is at a distance m from the upper side of the lower grinding disc 3, the first electric push rod 102 will stop pushing. At this time, the lubricating fluid remaining on the lower grinding disc 3 will flow into the guide groove 3001 on the lower grinding disc 3, and then flow into the drainage hole 3002 on the lower grinding disc 3 under the guidance of the guide groove 3001 with the middle high and the two ends low, and then pass through the drainage hole 3002 and fall onto the connecting plate 103, and then pass through the leakage hole 10301 on the connecting plate 103, fall onto the fixed frame 101, and finally be discharged through the drainage groove 10101 on the fixed frame 101.

[0033] In addition, water is pumped to all water pipes 105 through a water pump, thereby inputting the water into the water storage space 10402 on the corresponding support frame 104, and then sprayed out from the water spray trough 10403 on the support frame 104, thereby flushing the lubricating liquid and debris remaining on the lower grinding disc 3.

[0034] The additional technical effects of the present invention are as follows: Among them, such as Figure 6 As shown, each guide groove 3001 is set to be high in the middle and low on both sides in order to speed up the flow of the lubricating fluid.

[0035] Example 2: Based on Example 1, Figure 3 and Figure 7-Figure 9 As shown, it also includes a third electric push rod 301 and a limit ring 302; the part close to the center of the upper grinding disc 4 on the upper grinding disc 4 is the inner part, and the part away from the center is the outer part. Five third electric push rods 301 are bolted to the outside and the inside of the upper grinding disc 4; the corresponding telescopic ends of the third electric push rods 301 are commonly bolted to a limit ring 302.

[0036] It also includes a liquid scraping block 303 ; a plurality of liquid scraping blocks 303 are provided on the facing sides of the two limiting rings 302 .

[0037] In order to better scrape off the lubricating liquid on the limiting gear 10 , the free end of each scraping block 303 is configured to be arc-shaped.

[0038] In order to prevent the limiting ring 302 and the scraping block 303 from damaging the limiting gear 10 , all the limiting rings 302 and the scraping block 303 are made of rubber.

[0039] In the process of the second electric push rod 202 pushing the moving ring 203 upward and thus pushing the limit gear 10 to move upward, in order to avoid the limit gear 10 from moving upward too much, causing the upper side of the limit gear 10 to contact the lower side of the upper grinding disk 4, so that the limit gear 10 is worn by the upper grinding disk 4, the limit gear 10 is limited by the limit ring 302. Looking from top to bottom as a reference, the limit ring 302 should be higher than the upper grinding disk 41-3m, thereby avoiding the upper side of the limit gear 10 from contacting the lower side of the upper grinding disk 4, so that the limit gear 10 is worn by the upper grinding disk 4.

[0040] The lubricating fluid injected from the upper grinding disc 4 to the workpiece 11 will partially fall on the limiting gear 10. At the same time, some of the debris generated by grinding the workpiece 11 will also fall on the limiting gear 10, causing a large amount of debris and lubricating fluid on the limiting gear 10 to accumulate on the limiting gear 10 and then flow to the lower grinding disc 3. However, some of the debris and lubricating fluid will flow through the gap between the limiting gear 10 and the workpiece 11 to the lower grinding disc 3, and then after the suction pump 205 extracts the lubricating fluid containing debris in the gap between the limiting gear 10 and the workpiece 11, the lubricating fluid containing debris will quickly accumulate again. Therefore, after the limiting gear 10 is pushed upward by the movable ring 203, it will contact the limiting ring 302, so that the lubricating fluid carrying debris on the limiting gear 10 can be scraped onto the lower grinding disc 3 by the scraper block 303 on the limiting ring 302, thereby preventing a large amount of debris and lubricating fluid on the limiting gear 10 from accumulating on the limiting gear 10.

[0041] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge of those skilled in the art without departing from the spirit of the present invention.
