Description

Technical Field

[0001] The invention relates to the technical field of grinding and polishing machines, in particular to a water drill grinding and polishing machine. Background Art

[0002] A water diamond grinding and polishing machine is a specialized grinding and polishing device typically consisting of a main unit and several auxiliary devices, such as abrasive discs, a water tank, and a vacuum cleaner. It can be used to process the surfaces of various materials, such as stone, glass, ceramics, and even water diamond bead blanks. Its operating principle is to utilize the friction generated by the abrasive and the grinding tool, as well as the impact force of a liquid (usually water), to remove surface irregularities, stains, and scratches until the desired surface finish and flatness are achieved.

[0003] The grinding pressure and speed of the water drill grinder are very important factors affecting the grinding and polishing effect. When the grinding and polishing force is too large or the time is too long, the surface of the blank will not only suffer excessive wear, but may even have serious defects such as cracks and deformation, which not only wastes raw materials, but also greatly reduces the yield and quality of the finished product. On the contrary, if the grinding and polishing is insufficient, the defects and unevenness on the surface of the blank cannot be effectively removed, and the processing cannot achieve the expected effect.

[0004] However, parameters such as force, speed and abrasive selection in the grinding and polishing process of traditional grinders and polishers are often difficult to accurately control, which makes it time-consuming and labor-intensive for operators to inspect the grinding and polishing effects of blanks, and makes it difficult to accurately control the grinding and polishing effects of each blank.

[0020] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] The present invention will be further described below with reference to the embodiments. Example

[0022] Refer to the attached Figure 1 - Figure 6 As shown, a water drill grinding and polishing machine includes a machine base 1, on which a support assembly 2, a clamping assembly 3, a grinding disc 5, a drive assembly 7 and a detection assembly are provided. Two sets of second rotating shafts 501 are rotatably installed on the machine base 1 and located on both sides of the first rotating shaft 201. The second rotating shaft 501 is fixedly connected to the grinding disc 5. Two sets of unidirectional motors are provided on the machine base 1. The unidirectional motor is coaxially connected to the second rotating shaft 501. The unidirectional motor controls the rotation of the grinding disc 5 through the second rotating shaft 501 to perform grinding and polishing operations on the blank 8. The drive assembly 7 drives the support assembly 2 to rotate intermittently, rotating 90 degrees each time. Four working areas are arranged in an annular manner on the support assembly 2. Between the two opposite grinding and polishing areas, one is a loading area and the other is a flipping area. Figure 1 、 Figure 2 As shown, the clamping assembly 3 close to the rack 207 side is located in the flipping area, the supporting assembly 2 rotates counterclockwise, and the blank 8 is fixed on the clamping assembly 3 in the loading area. The driving assembly 7 drives the supporting assembly 2 to rotate 90 degrees and rotate the clamping assembly 3 to the grinding and polishing area. The grinding wheel 5 grinds the blank 8 thereon, and then the driving assembly 7 drives the supporting assembly 2 to rotate 90 degrees on both sides. During this process, the clamping assembly 3 will perform a 180-degree flip, which is convenient for grinding the other side of the blank 8 in the second grinding and polishing area. A material receiving device is provided between the second grinding area and the loading area. After the two grindings are completed, the driving assembly 7 drives the supporting assembly 2 to rotate 90 degrees again. In the process of moving this group of clamping assemblies 3 to the loading area, the clamping assembly 3 will release the clamping of the blank 8, and the blank 8 automatically falls into the material receiving device.

[0023] Refer to the attached Figure 5As shown, the support assembly 2 includes a first rotating shaft 201 rotatably mounted on the machine base 1, and the driving assembly 7 includes a groove wheel 701, a third rotating shaft 702, a dial 703, a guide rod 704 and a dial block 705. The groove wheel 701 is fixedly sleeved on the first rotating shaft 201, and the groove wheel 701 drives the support frame 202 to rotate through the first rotating shaft 201. The third rotating shaft 702 is rotatably mounted on the machine base 1, and the third rotating shaft 702 is located on one side of the groove wheel 701. An intermittent motor is provided on the machine base 1, and the intermittent motor is coaxially connected to the third rotating shaft 702. The intermittent motor drives the third rotating shaft 702 to rotate. The dial 703 and the guide rod 704 are all fixedly mounted on the third rotating shaft 702, and the guide rod 704 is located below the dial 703. The dial 703 and the guide rod 704 rotate together with the third rotating shaft 702. The dial block 705 is fixedly mounted on the guide rod 704, and the rotating dial block 705 drives the groove wheel 701 to rotate intermittently.

[0024] Refer to the attached Figure 1 and Figure 4 As shown, a support frame 202 is fixedly installed on the first rotating shaft 201, an annular frame 203 is provided on the outer ring of the support frame 202, and multiple groups of connecting rods 204 are provided between the support frame 202 and the annular frame 203. The frame composed of the support frame 202, the annular frame 203 and the connecting rods 204 is used to support the rotation of multiple groups of clamping components 3.

[0025] Specifically, the clamping assembly 3 includes a plurality of support tubes 301 rotatably inserted on the support frame 202, and the support tubes 301 pass through the annular frame 203, and the end of the support tube 301 is fixedly installed with a station ring 302, and the blank 8 is placed in the center of the station ring 302. The inner ring of the station ring 302 is provided with an annular groove, and an airbag 303 is fixedly installed in the annular groove, and the support tube 301 and the end are connected to the airbag 303. The airbag 303 is made of elastic rubber material, and the blank 8 is placed in the center of the station ring 302. The method of internal gas injection in 03 utilizes the airbag 303 to clamp the blank 8, and a signal button 306 is fixedly installed in the annular groove. A solenoid valve is provided at the end of the support tube 301 away from the work station ring 302, and the signal button 306 is electrically connected to the solenoid valve. When the airbag 303 is full of gas and can no longer be injected with gas, the inflated airbag 303 will touch the signal button 306 for a long time, and the signal button 306 will send an electrical signal to the solenoid valve, causing the solenoid valve to close the gas injection end of the support tube 301, stop gas injection and avoid gas leakage in the support tube 301.

[0026] Furthermore, a connecting disk 205 is fixedly provided on the first rotating shaft 201, and the connecting disk 205 is located below the support frame 202. A group of racks 207 are fixedly installed on the connecting disk 205, and the racks 207 are arranged in an arc shape. A gear 305 is fixedly installed on the support tube 301, and the gear 305 is engaged with the rack 207 for transmission. When the gear 305 passes through the rack 207, the gear 305 rotates 180 degrees to complete the flipping of the blank 8.

[0027] Furthermore, multiple groups of air vents 208 are provided on the support frame 202, and the ends of each group of air vents 208 correspond one-to-one to the end positions of each group of support tubes 301. The air vents 208 are connected to the support tubes 301. A connecting frame 6 is fixedly installed between the two groups of brackets 4. The connecting frame 6 supports the electric push rod 601 suspended above the support assembly 2. The electric push rod 601 is fixedly installed on the connecting frame 6. The electric push rod 601 pushes the air pump 602 to approach the air vent 208. The telescopic end of the electric push rod 601 is fixedly connected to the air pump 602. When the air outlet end of the air pump 602 is inserted into the air vent 208, air is injected into the air vent 208.

[0028] Refer to the attached Figure 1 and Figure 4 As shown, the detection component is used to monitor the grinding degree of the blank 8. The detection component includes a bracket 4 fixedly mounted on the machine base 1. The bracket 4 supports the hollow block 401 suspended above the clamping component 3. One end of the bracket 4 is fixedly connected to the hollow block 401. A sliding block 402 is slidably mounted in the hollow block 401. The sliding block 402 supports the pressing block 403 to slide vertically along the inner wall of the hollow block 401 without slipping. A pressing block 403 is fixedly mounted on the bottom of the sliding block 402. A through hole is provided at the bottom of the hollow block 401. The end of the pressing block 403 is slidably inserted into the through hole. When the blank 8 is ground by the grinding disc 5, the pressing block 403 presses the blank 8 to prevent the blank 8 from being squeezed out of the clamping component 3.

[0029] Because the rough surface of the blank 8 before grinding will cause the height of different blanks 8 to be different, the blank 8 cannot be directly moved to the bottom of the pressing block 403, and then the pressing block 403 cannot press the blank 8. Therefore, a sliding groove 4011 is provided on one side of the hollow block 401, and a connecting piece 404 is slidably inserted on the sliding groove 4011. One end of the connecting piece 404 is fixedly connected to the sliding block 402, and the other end of the connecting piece 404 is fixedly installed with a height judging block 405, and the height judging block 405 is provided with an inverted inclined surface. Limit blocks 304 are fixedly installed on the upper and lower sides of the work station ring 302, and the two sets of limit blocks 304 are set at relatively diagonal positions. When the moving clamping assembly 3 approaches the bracket 4, the limit blocks 304 will first contact the height judgment block 405, and use the connecting piece 404 to lift the pressing block 403 through the inverted inclined surface of the height judgment block 405, leaving enough space for the blank 8 to enter. The purpose of setting two sets of limit blocks 304 is because the work station ring 302 will flip over, and one limit block 304 needs to always face upwards.

[0030] Specifically, an infrared rangefinder 407 is fixedly installed in the hollow block 401, and a spring 406 is fixedly connected between the sliding block 402 and the sliding block 402. The spring 406 gives a certain thrust to the pressing block 403 through the sliding block 402. The pressing block 403 adds a certain elastic pushing force on the basis of its own weight pressure to press the blank 8. During the grinding process of the blank 8, the spring 406 pushes the pressing block 403 to be pressed on the blank 8 through the sliding block 402, and then the infrared rangefinder 407 is used to detect the height difference change of the spring 406 to judge the grinding degree of the blank 8, so as to avoid the problem of insufficient grinding or excessive grinding.

[0031] Furthermore, two groups of support plates 206 are fixedly connected to the diagonally opposite sides of the connecting disk 205. One of the curved edges of the support plates 206 matches the outer contour of the grinding disk 5. The support plates 206 support the blank 8, facilitate loading, and help adjust the clamping height. When the height judgment block 405 contacts the blank 8, the blank 8 will not be pushed out of the airbag 303 by the height judgment block 405 and fall.

[0032] The working process of a water drill grinding and polishing machine of this application is as follows: S1: First, place the blank 8 in the clamping assembly 3 in the loading area, start the electric push rod 601, and the electric push rod 601 pushes the air pump 602 close to the vent 208. The telescopic end of the electric push rod 601 is fixedly connected to the air pump 602. When the air outlet end of the air pump 602 is inserted into the vent 208, air is injected into the vent 208.

[0033] S2: Gas enters the airbag 303 through the support tube 301, and the inflated airbag 303 clamps the blank 8. When the gas in the airbag 303 is sufficient, the inflated airbag 303 will long-touch the signal button 306, and the signal button 306 will send an electrical signal to the solenoid valve, causing the solenoid valve to close the gas injection end of the support tube 301, stop gas injection and prevent gas leakage in the support tube 301. At the same time, the air pump 602 stops injecting gas, and the electric push rod 601 retracts the air pump 602 to prevent the air pump 602 from affecting the rotation of the support frame 202.

[0034] S3: Restart the intermittent motor, which drives the third rotating shaft 702 to rotate. The third rotating shaft 702 drives the dial 703 and the guide rod 704 to rotate. The shift block 705 moves together with the guide rod 704. The rotating shift block 705 drives the groove wheel 701 to rotate intermittently 90 degrees. Then, the groove wheel 701 drives the support frame 202 to rotate through the first rotating shaft 201. The clamping assembly 3 moves horizontally 90 degrees to the grinding and polishing area along with the support assembly 2.

[0035] S4: When the moving clamping assembly 3 approaches the bracket 4, the limit block 304 will first contact the height judging block 405, and use the connecting piece 404 to lift the pressing block 403 through the inverted slope of the height judging block 405, leaving enough space for the blank 8 to enter. When the blank 8 moves to the bottom of the pressing block 403, the pressing block 403 adds a certain elastic pushing force of the spring 406 on the basis of its own weight pressure to press the blank 8, and start the unidirectional motor. The unidirectional motor controls the rotation of the grinding disc 5 through the second rotating shaft 501 to grind and polish the blank 8. The infrared rangefinder 407 detects the degree of polishing of the blank 8 in real time through the height change of the pressing block 403.

[0036] S5: After the first grinding, the driving assembly 7 drives the supporting assembly 2 to rotate 90 degrees on both sides. During this process, the gear 305 passes through the rack 207, and the gear 305 drives the supporting tube 301 to flip 180 degrees, thereby completing the flipping of the blank 8, so as to facilitate the grinding of the other side of the blank 8 in the second grinding and polishing area.

[0037] S6: Before the second grinding, the blank 8 will pass through the second bracket 4. The connecting piece 404 and the pressing block 403 will adjust the height position of the blank 8 in the work station ring 302 so that the surface to be processed of the blank 8 fits the surface of the grinding wheel 5, and then the grinding wheel 5 processes it.

[0038] S7: After the two grindings are completed, the driving component 7 drives the supporting component 2 to rotate 90 degrees again. In the process of moving the group of clamping components 3 to the upper material area, the solenoid valve at the end of the group of supporting tubes 301 will be opened, and the supporting tubes 301 will release the gas therein through the vent 208. The airbag 303 will be deflated after leakage, and the clamping of the blank 8 will be automatically released. The blank 8 will automatically fall into the material receiving device, and the processing and collection of the blank 8 will be completed.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
