Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of diamond and grinding processing, and particularly relates to a diamond grinding disc device and a system thereof. BACKGROUND

[0002] The existing diamond raw material grinding device adopts a "global fixed parameter" mode when supplying cooling liquid, that is, the cooling liquid spray head continuously sprays at a preset rate and temperature, which cannot match the dynamic position of the jig ring. When the jig ring drives the diamond raw material to approach the spray head area, excessive cooling liquid is easy to accumulate on the grinding surface, which not only causes resource waste, but also dilutes the grinding pressure and affects the grinding efficiency. When the jig ring is far away from the spray head area, the fixed spray intensity is insufficient to quickly remove the diamond powder generated during grinding, which causes the powder to accumulate on the surface of the grinding disc.

[0003] In addition, the harm of residual powder is particularly significant. The diamond powder has high hardness, and if it is not removed in real time, it is easy to be mixed between the raw material and the grinding disc to form "secondary grinding", which causes scratches and flatness deviation on the surface of the raw material, and reduces the qualified rate of the finished product.

[0004] In summary, for the contradiction between the grinding efficiency, effect and energy consumption of the above-mentioned diamond raw material, and the adverse phenomena occurring in the grinding quality control process, how to effectively overcome it becomes a technical problem to be solved. SUMMARY

[0005] To solve the above technical problems, the present application is realized by the following technical scheme:

[0006] The present application provides a diamond grinding disc device, which comprises a grinding disc for diamond raw material grinding, a jig ring for placing the diamond raw material to be processed, a driving gear and an outer gear ring. The driving gear is located in the inner periphery of the grinding disc, and the outer gear ring is located in the outer periphery of the grinding disc. The jig ring is located between the driving gear and the outer gear ring, the outer ring side of the jig ring is provided with a tooth opening, and the tooth opening is engaged with the driving gear and the outer gear ring respectively. The adjacent tooth openings of the outer gear ring are provided with a tooth groove, the outer gear ring is provided with a plurality of radially distributed threaded holes, and the threaded holes are aligned and penetrated with the tooth grooves. The outer gear ring is further provided with a plurality of photoelectric probes, a plurality of grinding cooling liquid spray heads and a gas-liquid mixed spray head, the photoelectric probes and the grinding cooling liquid spray heads are alternately arranged, and the gas-liquid mixed spray head comprises a gas pipe and a liquid pipe.

[0007] Preferably, the device further comprises a driving device, the output end of the driving device is connected with the driving gear, and the driving device comprises a servo driving motor and a reduction gear.

[0008] Preferably, the jig ring is a plurality of, and the plurality of jig rings are equally spaced between the driving gear and the outer gear ring.

[0009] Preferably, an inner gap is reserved between the drive gear and the grinding disc, and an outer gap is reserved between the outer gear ring and the grinding disc.

[0010] Preferably, the photoelectric probes and grinding coolant nozzles are arranged alternately and evenly along the circumferential direction of the outer toothed ring. The circumferential distance between two adjacent photoelectric probes is equal to the circumferential distance between two adjacent grinding coolant nozzles, and the detection direction of the photoelectric probes and the spraying direction of the grinding coolant nozzles are both directed towards the central area of ​​the grinding disc.

[0011] Preferably, the photoelectric probe, the grinding coolant nozzle, and the gas-liquid mixing nozzle are all equipped with a screw head structure, and each screw head structure is screwed into the threaded hole of the external toothed ring. The outer circumferential surface of the screw head structure is provided with an external thread, which is adapted to the internal thread of the threaded hole of the external toothed ring.

[0012] Preferably, the gas pipe of the gas-liquid mixing nozzle is connected to an external gas source, and the liquid pipe is connected to an external coolant supply device. A gas control valve is installed on the gas pipe, and a liquid control valve is installed on the liquid pipe.

[0013] This invention provides a control system for a diamond grinding disc device, the control system comprising the following:

[0014] The encoding unit is used to encode the circumferential positions of the photoelectric probe, the grinding coolant nozzle, and the gas-liquid mixing nozzle relative to the outer toothed ring.

[0015] The photoelectric monitoring and analysis unit is electrically connected to the photoelectric probe to acquire distance information detected by the photoelectric probe and analyze the obstruction situation of the fixture ring.

[0016] The motion trend analysis unit, connected to the photoelectric monitoring and analysis unit, groups photoelectric probes with adjacent coded positions that have detected the fixture ring into the same monitoring group. It analyzes the motion trend of the fixture ring based on changes in the distance parameters of the photoelectric probes within the same monitoring group, and simultaneously identifies the grinding coolant nozzles within the same monitoring group area. The motion trend analysis unit also groups adjacent photoelectric probes that have not detected the fixture ring into a zero-monitoring area group. The motion trend includes an approaching motion trend and a moving-away motion trend. The approaching motion trend is the motion trend when the photoelectric probe detects a gradually decreasing distance, while the moving-away motion trend is the motion trend when the photoelectric probe detects a gradually increasing distance.

[0017] The cooling output control unit is connected to the motion trend analysis unit and outputs control to the grinding coolant nozzle. The output intensity of the grinding coolant nozzle is controlled based on the motion trend and distance parameters of the fixture ring. The output intensity of the grinding coolant nozzle includes the grinding coolant spray rate and the grinding coolant temperature.

[0018] The present invention also provides a control method for a diamond grinding disc device, the details of which are as follows:

[0019] S1. Start the grinding disc device, drive the gear to rotate steadily at the preset speed, drive multiple jig rings to perform planetary motion, and the diamond raw material to be processed starts grinding operation synchronously with the jig rings.

[0020] S2. Simultaneously, the photoelectric monitoring and analysis unit is activated to collect distance information detected by each photoelectric probe in real time.

[0021] S3. The motion trend analysis unit filters out the photoelectric probes that detect the jig ring, assigns photoelectric probes with adjacent coded positions to the same monitoring group, and locks the grinding coolant nozzles in the corresponding area of ​​the group.

[0022] S4. Based on the changes in the distance parameters of the photoelectric probes within the same monitoring group, determine the movement trend of the fixture ring and identify whether it is a trend of moving closer or moving further away.

[0023] S5. When the motion trend is close to the motion trend, the spray rate and temperature of the grinding coolant from the grinding coolant nozzle both decrease. When the motion trend is far from the motion trend, the spray rate and temperature of the grinding coolant from the grinding coolant nozzle both increase.

[0024] S6. The grinding coolant nozzles in the zero-monitoring zone group remove residual grinding powder from the surface of the grinding disc by maximizing the spray rate and temperature away from the motion trend.

[0025] S7. After the grinding operation is completed, start the gas-liquid mixing nozzle, first spray cleaning fluid through the liquid pipe to clean the grinding disc, then close the liquid pipe and open the gas pipe to dry the grinding disc.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] In this invention, by alternating and uniformly arranging photoelectric probes and grinding coolant nozzles, combined with an encoding unit and a motion trend analysis unit, the position and motion trend (approaching or moving away) of the jig ring can be monitored in real time. The cooling output control unit dynamically adjusts the coolant output intensity. When the jig ring approaches, the spray speed and temperature are reduced to retain the coolant needed for lubrication while avoiding waste; when it moves away, the parameters are increased for rapid powder removal. Simultaneously, the zero-monitoring area performs powder removal control according to high-speed, non-low-temperature grinding coolant flow parameters, removing residual powder from the surface of the grinding disc in real time. This prevents powder from being trapped between the raw material and the grinding disc, affecting processing accuracy and improving the surface smoothness and dimensional accuracy of the finished diamond product.

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0034] Example 1: This invention designs a diamond grinding disc device, combined with... Figures 1 to 3 Its specific structural configuration is as follows:

[0035] (I) Core load-bearing and transmission components

[0036] Grinding disc 1: As the core bearing component for grinding diamond raw materials, it provides a basic working plane for grinding operations. The diamond raw materials to be processed are placed on its surface through the jig ring 2, and the grinding process is achieved in conjunction with the planetary motion of the jig ring 2.

[0037] Fixture ring 2: Used to hold the diamond raw material to be processed. There are multiple fixture rings 2, and they are evenly distributed between the drive gear 3 and the external gear ring 4. The outer ring side of the fixture ring 2 is provided with teeth, which mesh with the drive gear 3 and the external gear ring 4 respectively. Under the drive of the drive gear 3, it can perform planetary motion along the trajectory of the external gear ring 4, so that the diamond raw material to be processed inside can be ground synchronously on the grinding disc 1.

[0038] Drive gear 3: Located inside the grinding disc 1, it is connected to the output end of the drive equipment (servo drive motor and reduction gear) and is the core of power transmission for the movement of fixture ring 2. When drive gear 3 rotates stably at a preset speed, it drives multiple fixture rings 2 to perform planetary motion synchronously through meshing with the outer ring teeth of fixture ring 2. At the same time, an inner clearance 5 is reserved between drive gear 3 and grinding disc 1 to avoid frictional interference between drive gear 3 and grinding disc 1 during rotation.

[0039] External toothed ring 4: Located around the grinding disc 1, it meshes with the outer ring teeth of the fixture ring 2 to limit the movement trajectory of the fixture ring 2 and ensure that the fixture ring 2 performs stable planetary motion. An external gap 6 is reserved between the external toothed ring 4 and the grinding disc 1 to prevent friction between the external toothed ring 4 and the grinding disc 1 during operation; a tooth groove 401 is provided between adjacent teeth of the external toothed ring 4, and the external toothed ring 4 has multiple radially distributed threaded holes 402, which are aligned with and pass through the tooth grooves 401 for mounting photoelectric probe 7, grinding coolant nozzle 8 and gas-liquid mixing nozzle 9.

[0040] (ii) Gap structure

[0041] Inner clearance 5: Reserved between the drive gear 3 and the grinding disc 1. Its function is to prevent the drive gear 3 from directly contacting and rubbing against the grinding disc 1 when rotating the drive jig ring 2, thus ensuring the smooth rotation of the drive gear 3 and the surface integrity of the grinding disc 1.

[0042] External clearance 6: Reserved between the external gear ring 4 and the grinding disc 1 to prevent frictional interference between the external gear ring 4 and the grinding disc 1 when restricting the movement trajectory of the fixture ring 2, thus ensuring the normal operation of the grinding disc 1 and the structural stability of the external gear ring 4.

[0043] (III) Detection and Spraying Components

[0044] Multiple photoelectric probes 7 are mounted on the external gear ring 4 and have a screw head structure (the outer circumferential surface of the screw head structure has an external thread that matches the internal thread of the threaded hole 402 of the external gear ring 4). The photoelectric probes 7 are evenly and alternately arranged with the grinding coolant nozzles 8 along the circumferential direction of the external gear ring 4. The circumferential distance between two adjacent photoelectric probes 7 is equal to the circumferential distance between two adjacent grinding coolant nozzles 8, and the detection direction of the photoelectric probes 7 is towards the center area of ​​the grinding disc 1. Their function is to detect the distance information between the probes and the fixture ring 2 in real time, providing data support for analyzing the obstruction and movement trends of the fixture ring 2, and they are electrically connected to the photoelectric monitoring and analysis unit in the control system.

[0045] Multiple grinding coolant nozzles 8 are mounted on the outer gear ring 4 and also have a threaded head structure, which is screwed into the threaded hole 402 of the outer gear ring 4. They are evenly and alternately arranged with the photoelectric probe 7 along the circumferential direction of the outer gear ring 4, with the spray direction facing the center area of ​​the grinding disc 1. They are used to spray grinding coolant onto the working area of ​​the grinding disc 1 to achieve cooling, lubrication, and removal of grinding powder. The grinding coolant nozzles 8 are connected to the cooling output control unit in the control system. Their output intensity (including the grinding coolant spray rate and grinding coolant temperature) can be adjusted by the cooling output control unit according to the movement trend and distance parameters of the fixture ring 2.

[0046] Gas-liquid mixing nozzle 9: Mounted on the outer gear ring 4, it features a threaded head structure that is screwed into the threaded hole 402 of the outer gear ring 4. It includes an air pipe 901 and a liquid pipe 902. The air pipe 901 is connected to an external air source and is equipped with a gas control valve (for controlling the gas flow). The liquid pipe 902 is connected to an external coolant supply device and is equipped with a liquid control valve (for controlling the liquid flow). The core function of the gas-liquid mixing nozzle 9 is to clean and dry the grinding disc 1 after the grinding operation: first, cleaning fluid is sprayed through the liquid pipe 902 to clean the grinding disc 1; after cleaning, the liquid pipe 902 is closed, and the air pipe 901 is opened to deliver gas to dry the grinding disc 1.

[0047] (iv) Drive equipment

[0048] It includes a servo drive motor and a reduction gear, the output of which is connected to the drive gear 3 to provide power to the drive gear 3. During operation, the servo drive motor, together with the reduction gear, can drive the drive gear 3 to rotate stably at a preset speed. Then, through the meshing relationship between the drive gear 3 and the jig ring 2, it drives multiple jig rings 2 to perform planetary motion, ensuring that the grinding operation is stable and controllable.

[0049] Example 2: The present invention designs a control system for a diamond grinding disc device. The control system realizes the monitoring of the motion state of the jig ring 2 and the intelligent control of the grinding coolant nozzle 8 and the gas-liquid mixing nozzle 9. The control system includes an encoding unit, a photoelectric monitoring and analysis unit, a motion trend analysis unit, and a cooling output control unit.

[0050] (a) Coding unit

[0051] This coding is used to encode the circumferential positions of the photoelectric probe 7, the grinding coolant nozzle 8, and the gas-liquid mixing nozzle 9 relative to the outer toothed ring 4, generating a unique position identifier for each component. This coding provides a positional basis for subsequently determining the relative positional relationships of each component, dividing monitoring groups and zero-monitoring area groups, and accurately matching the grinding coolant nozzle 8 with the photoelectric probe 7.

[0052] (II) Photoelectric Monitoring and Analysis Unit

[0053] Electrically connected to the photoelectric probe 7, it can receive and collect the distance information between each photoelectric probe 7 and the fixture ring 2 in real time. At the same time, it analyzes the occlusion of the fixture ring 2 based on the distance information (i.e., determines whether the current photoelectric probe 7 is blocked by the fixture ring 2, and then determines whether the fixture ring 2 is detected), and transmits the occlusion status and corresponding distance data to the motion trend analysis unit in real time.

[0054] (III) Movement Trend Analysis Unit

[0055] Connected to the photoelectric monitoring and analysis unit, it is the core analysis module of the control system, and its specific functions include:

[0056] Monitoring group division and nozzle matching: Photoelectric probes 7 that are identified as "detecting fixture ring 2" by the photoelectric monitoring and analysis unit are selected, and these photoelectric probes 7 with adjacent coding positions are assigned to the same monitoring group. At the same time, based on the coding position of the photoelectric probes 7 within the monitoring group, the corresponding grinding coolant nozzles 8 within the monitoring group area are determined, realizing the regional correspondence of "photoelectric probe-nozzle".

[0057] Motion trend judgment: Based on the changes in distance parameters transmitted in real time by each photoelectric probe 7 within the same monitoring group, the motion trend of the fixture ring 2 is analyzed. The motion trend is divided into two categories: one is the approaching motion trend, that is, the distance detected by the photoelectric probe 7 between itself and the fixture ring 2 gradually decreases; the other is the moving away motion trend, that is, the distance detected by the photoelectric probe 7 between itself and the fixture ring 2 gradually increases.

[0058] Zero monitoring area group division: Photoelectric probes 7 with adjacent coding positions and determined by the photoelectric monitoring and analysis unit as "not detected jig ring 2" are classified into the zero monitoring area group, and the grinding coolant nozzles 8 corresponding to this area group are determined.

[0059] (iv) Cooling output control unit

[0060] Connected to the motion trend analysis unit, it is used to precisely control the output intensity (grinding coolant spray rate, grinding coolant temperature) of the grinding coolant nozzle 8 based on the "motion trend of jig ring 2" and "distance parameters" output by the motion trend analysis unit. The specific control logic is as follows:

[0061] Proximity Movement Trend Control: When the fixture ring 2 is in a proximity movement trend, the spray rate and temperature of the grinding coolant from the grinding coolant nozzle 8 in the corresponding monitoring group area are reduced; and the smaller the distance parameter (the closer the fixture ring 2 is to the photoelectric probe 7), the lower the spray rate and temperature of the grinding coolant, until the spray rate drops to zero (at this time, the outlet of the grinding coolant nozzle 8 is completely blocked by the fixture ring 2, and the spraying has no actual effect), and the temperature of the grinding coolant drops to the preset minimum value T. min This control can preheat the area to be ground and retain an appropriate amount of coolant on the surface of the grinding disc 1 for lubrication.

[0062] Distance-of-motion control: When the fixture ring 2 is in a distance-of-motion trend, the spray rate and temperature of the grinding coolant nozzle 8 in the corresponding monitoring area are increased. The greater the distance parameter (the farther the fixture ring 2 is from the photoelectric probe 7), the higher the spray rate and the grinding coolant temperature, until the spray rate reaches the preset maximum value V. max、 The grinding coolant temperature rises to the preset maximum value T maxThis control can quickly flush away residual grinding powder on the surface of the grinding disc 1, while avoiding energy waste caused by low-temperature coolant.

[0063] Zero-monitoring zone group control: Within the zero-monitoring zone group, the grinding coolant nozzle 8 is controlled according to the maximum parameter of "away from motion trend" (spray rate = V). max Grinding coolant temperature = T max Spraying liquid thoroughly removes the grinding powder remaining on the surface of the grinding disc 1, preventing the powder remaining after grinding in the upstream fixture ring 2 from adversely affecting the grinding accuracy of the raw material in the subsequent fixture ring 2.

[0064] Example 3: The present invention also designs a control method for a diamond grinding disc device, the details of which are as follows:

[0065] S1. Start the grinding disc device. The drive equipment (servo drive motor and reduction gear) drives the drive gear 3 to rotate stably at the preset speed. The drive gear 3 meshes with the outer ring teeth of the jig ring 2, driving multiple jig rings 2 to perform planetary motion. The diamond raw material to be processed placed in the jig ring 2 starts grinding on the grinding disc 1 synchronously with the jig ring 2.

[0066] S2. Simultaneously, the photoelectric monitoring and analysis unit is activated. This unit collects the distance information between each photoelectric probe 7 and the fixture ring 2 in real time, analyzes the obstruction of each photoelectric probe 7 by the fixture ring 2, and transmits the data to the motion trend analysis unit in real time.

[0067] S3. The motion trend analysis unit selects photoelectric probes 7 that "detect jig ring 2", assigns photoelectric probes 7 with adjacent coding positions to the same monitoring group, and locks the grinding coolant nozzles 8 in the corresponding area of ​​the monitoring group according to the coding position of the monitoring group.

[0068] S4. The motion trend analysis unit determines the motion trend of the fixture ring 2 based on the change in distance parameters of the photoelectric probe 7 within the same monitoring group, and determines whether it is a "moving trend towards" (distance gradually decreases) or a "moving trend away from" (distance gradually increases).

[0069] S5. The cooling output control unit controls the grinding coolant nozzle 8 in the corresponding area according to the judgment result of the motion trend analysis unit: if it is close to the motion trend, the spray rate and temperature are reduced; if it is far away from the motion trend, the spray rate and temperature are increased.

[0070] S6, within the zero-monitoring area group assigned by the motion trend analysis unit, the grinding coolant nozzle 8 is set to the maximum spray rate (V) "away from motion trend". max ) and temperature (T) max Spray liquid to remove residual grinding powder from the surface of grinding disc 1.

[0071] S7. After the grinding operation is completed, start the gas-liquid mixing nozzle 9: first, spray cleaning fluid through the liquid pipe 902 of the gas-liquid mixing nozzle 9 to clean the grinding disc 1. After cleaning, close the liquid pipe 902 and open the air pipe 901 to deliver gas to dry the grinding disc 1, thus completing the entire grinding process.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
