[0002] The manufacturing process of diamonds generally includes marking, splitting rough stones, shaping and petaling, and polishing. Among them, shaping and petaling, and polishing are the most complex and cumbersome and have extremely high requirements for operators. Traditional diamond shaping is to install the diamond blank on a high-speed rotating lathe, and then use a diamond on another arm to cut the rotating diamond blank into common flower shapes or other special shapes according to design requirements.

[0003] During the process of diamond processing by existing diamond grinding devices, the dust generated during diamond grinding is prone to splash, which will pose a threat to the health of workers. At the same time, the splashed dust adheres to a large area of the device surface, making it difficult to clean. If abrasive or grinding fluid is used, it will further increase the cleaning difficulty of the device and the difficulty of dust collection and treatment. Summary of the Invention

Detailed implementation

[0027] Hereinafter, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art.

[0028] As Figures 1 to 10 shown, an embodiment of the present invention provides a multi-station diamond grinding numerical control machine tool, including a vertical plate 101. A base 102, a workbench 103, and a top table 104 are fixedly connected to the surface of the vertical plate 101 in sequence from bottom to top. An air pump 107 is installed on the bottom surface of the workbench 103. A plurality of diamond detectors 105 are fixedly connected to the upper surface of the workbench 103 in a circular array. A wiping block 106 is provided on one side of each diamond detector 105. The wiping block 106 is fixedly connected to the workbench 103. It further includes: A plurality of linear slides 305 are arranged in a circular array between the top table 104 and the workbench 103. A DD direct drive multi-axis robotic arm 306 is installed on the slide surface of each linear slide 305. A rotary grinding disc 201 is provided on the surface of the workbench 103 for grinding diamonds. A liquid supply pipe 204 is provided above the rotary grinding disc 201. The liquid supply pipe 204 is used for outputting abrasive or grinding fluid. An out-liquid adjusting member is provided inside the liquid supply pipe 204 to adjust the out-liquid amount of the abrasive or grinding fluid output on the surface of the rotary grinding disc 201 through the out-liquid adjusting member. An air return cylinder 203 is provided on the surface of the liquid supply pipe 204. A first restraint ring 229 and a second restraint ring 230 are provided on the surface of the workbench 103. By operating the air pump 107, the airflow above the rotary grinding disc 201 is sucked in from one end of the air return cylinder 203 and blown out through the annular air gap formed between the first restraint ring 229 and the second restraint ring 230, so as to form an air wall above the rotary grinding disc 201. The air wall is used to restrain the dust and splashed grinding fluid or abrasive generated during the diamond grinding process. A filtering member is provided on the surface of the top table 104. Through the filtering of the filtering member, the gas blown out through the annular air gap between the first restraint ring 229 and the second restraint ring 230 is kept dry and clean.

[0029] In an embodiment of the present invention, when diamond grinding work is carried out, an external liquid storage tank and a pump body (not shown in the figure) are connected to the top end of the liquid supply pipe 204 through a pipeline (not shown in the figure). The temperature change on the surface of the rotating grinding disc 201 can be monitored by a sensor, and the flow rate of the grinding fluid or abrasive pumped into the liquid supply pipe 204 by the pump body is adjusted according to the temperature change of the rotating grinding disc 201. Through the setting of the liquid outlet adjusting member, the liquid supply pipe 204 adjusts the liquid outlet mode according to the hydraulic pressure pumped by the pump body to maintain a good liquid supply effect; When diamond grinding work starts simultaneously at multiple workstations, the rotating grinding disc 201 heats up quickly, and more abrasive or grinding fluid is required. Therefore, it is necessary to increase the output flow rate of the liquid, that is, increase the amount of liquid pumped into the liquid supply pipe 204.

[0030] When diamond grinding work is carried out, under the action of the operation of the air pump 107, air flow is blown out through the annular air gap formed between the first restraint ring 229 and the second restraint ring 230, and is inhaled through the bottom opening of the air return cylinder 203, thereby forming a hood-shaped air wall. The dust, splashing grinding fluid or abrasive generated during the diamond grinding process is confined inside the hood-shaped air wall, reducing dust pollution and facilitating the cleaning of the device and the collection and treatment of dust; Through the setting of the filter element, a dry and clean air flow is blown out through the annular air gap between the first restraint ring 229 and the second restraint ring 230, facilitating the air drying of the diamond during the grinding process through the dry and clean air flow, so as to facilitate the detection of the diamond by the diamond detector 105. The setting of the wiping block 106 can wipe the diamond, further improving the detection accuracy of the diamond detector 105.

[0031] A driving motor 202 is installed on the bottom surface of the workbench 103. The rotating grinding disc 201 is rotationally connected to the upper surface of the workbench 103 through a first bearing. The output shaft of the driving motor 202 is fixedly connected to the rotating grinding disc 201. A linear slide 305 is installed on the bottom surface of the top platform 104. A fixed arc-shaped baffle 307 is provided between the top platform 104 and the workbench 103. The fixed arc-shaped baffle 307 is fixedly connected to the top platform 104 and the workbench 103. An arc-shaped chute 303 is provided on the surface of the top platform 104. An active arc-shaped baffle 301 is slidably connected inside the arc-shaped chute 303. The active arc-shaped baffle 301 abuts against the fixed arc-shaped baffle 307. An L-shaped hook block 304 is hinged on the surface of the top platform 104. A handle 302 is fixedly connected to the surface of the active arc-shaped baffle 301.

[0032] In an embodiment of the present invention, the rotation of the rotary grinding disc 201 is caused by the operation of the drive motor 202 to facilitate the grinding of diamonds. By sliding the movable arc-shaped baffle 301, the movable arc-shaped baffle 301 is abutted against the upper surface of the workbench 103, so that the grinding area is constrained within the closed area surrounded by the fixed arc-shaped baffle 307, the movable arc-shaped baffle 301, the workbench 103 and the top table 104. By lifting the movable arc-shaped baffle 301 upward with the handle 302, the handle 302 slides upward inside the arc-shaped chute 303. The handle 302 on the surface of the movable arc-shaped baffle 301 is hooked by the L-shaped hook block 304, so that the position of the movable arc-shaped baffle 301 is fixed, and then the exposure state of the grinding area is maintained. By the combined use of the linear slide 305 and the DD direct drive multi-axis robotic arm 306, the diamond can be accurately adjusted in the rotation angle after being grasped by the DD direct drive multi-axis robotic arm 306 to facilitate the precise grinding of the diamond. The area where each linear slide 305 and the DD direct drive multi-axis robotic arm 306 are located represents a station area; The liquid outlet regulating member includes: A liquid volume regulating block 206 is fixedly connected inside the liquid supply pipe 204. A first annular groove 601 is formed inside the liquid volume regulating block 206. A second annular groove 603 is formed on the bottom surface of the liquid volume regulating block 206. A plurality of first cylindrical grooves 602 are formed in an annular array inside the liquid volume regulating block 206. The first cylindrical grooves 602 are all communicated with the inside of the first annular groove 601 and the first cylindrical grooves 602. A sliding plug block 604 is slidably connected inside the liquid volume regulating block 206. The sliding plug block 604 is located below the first annular groove 601. An unpenetrating circular groove 605 is formed on the upper surface of the sliding plug block 604. A third annular groove 606 is formed on the curved surface of the sliding plug block 604. A plurality of first connecting grooves 607 are formed in an annular array inside the third annular groove 606. The first connecting grooves 607 are communicated with the inside of the third annular groove 606 and the unpenetrating circular groove 605.

[0033] The curved surface of the liquid volume adjustment block 206 is provided with a fourth annular groove 613. The inside of the fourth annular groove 613 is provided with second connecting grooves 610 in an annular array. Above the sliding plug block 604, there is an annular plug block 609. The bottom surface of the annular plug block 609 is fixedly connected with a plurality of connecting columns 608 in an annular array. The connecting columns 608 are fixedly connected with the sliding plug block 604. The inner bottom surface of the liquid volume adjustment block 206 is fixedly connected with a limiting column 612. Inside the liquid volume adjustment block 206, there is a first spring 611. The two ends of the first spring 611 are respectively fixedly connected with the liquid volume adjustment block 206 and the sliding plug block 604. The annular plug block 609 is located above the first annular groove 601. The surface of the liquid supply pipe 204 is provided with a plurality of nozzle groups 614 in an annular array. The nozzle groups 614 are fixedly connected in the circular holes opened on the surface of the liquid supply pipe 204. The nozzle groups 614 are communicated with the inside of the fourth annular groove 613. The surface of the rotary grinding disc 201 is fixedly connected with a conical block 205. A part of the conical surface of the conical block 205 is located inside the liquid supply pipe 204.

[0034] In the embodiment of the present invention, during the process of pumping grinding fluid or abrasive into the inside of the liquid supply pipe 204, when the hydraulic pressure pumped into the inside of the liquid supply pipe 204 is small, the liquid enters the inside of the liquid volume adjustment block 206 through the gap between the inside of the annular plug block 609 and the connecting columns 608, and enters the inside of the first cylindrical groove 602 from the first annular groove 601. Finally, it flows out of the inside of the liquid volume adjustment block 206 from the second annular groove 603, and uniformly flows along the surface of the rotary grinding disc 201 under the guidance of the conical surface of the conical block 205 and the action of the centrifugal force generated by the rotation of the rotary grinding disc 201. When the hydraulic pressure pumped into the inside of the liquid supply pipe 204 gradually increases, the sliding plug block 604 moves along the inner wall of the liquid volume adjustment block 206 in the direction of compressing the first spring 611 under the action of the pressure until the annular plug block 609 blocks the first annular groove 601. At this time, the sliding plug block 604 moves to the state where the third annular groove 606 is communicated with the second connecting groove 610. Then, the liquid pumped into the inside of the liquid supply pipe 204 no longer flows out from the second annular groove 603. The liquid flows into the inside of the fourth annular groove 613 through the non-through circular groove 605, the first connecting groove 607 and the third annular groove 606, and is sprayed out through the nozzle groups 614, so that the surface of the rotary grinding disc 201 is uniformly coated with the grinding fluid or abrasive to ensure better cooling and grinding effects. The function of the limiting column 612 is to limit the lowest position of the sliding plug block 604, so that during the process of pumping a larger hydraulic pressure into the liquid supply pipe 204, the stable communication between the second connecting groove 610 and the third annular groove 606 is always maintained.

[0035] Above the rotating grinding disc 201, there is an air return cylinder 203. The air return cylinder 203 is fixedly connected in the second circular groove formed on the surface of the top table 104. The liquid supply pipe 204 is fixedly connected in the third circular groove formed on the upper surface of the air return cylinder 203. Inside the air return cylinder 203, there is a spiral lifting plate 401. The spiral lifting plate 401 is fixedly connected to the air return cylinder 203 and the liquid supply pipe 204. At the bottom surface of the air return cylinder 203, a number of guide rods 402 are fixedly connected in an annular array. The guide rods 402 are fixedly connected to the liquid supply pipe 204.

[0036] On the surface of the workbench 103, a number of air outlet round holes 227 are formed in an annular array. At the bottom surface of the workbench 103, an air supply box 225 is fixedly connected. The air supply box 225 is internally connected to the air outlet round holes 227. Inside the air supply box 225, a flow equalizing ring plate 226 is fixedly connected. The air supply box 225 is connected to the air outlet of the air pump 107 through a pipeline. On the surface of the workbench 103, a liquid leakage hole 228 is formed. The liquid leakage hole 228 is located between the rotating grinding disc 201 and the air supply box 225.

[0037] The second restraint ring 230 is arranged inside the first restraint ring 229. Both the second restraint ring 230 and the first restraint ring 229 are fixedly connected to the workbench 103. The annular air gap formed between the second restraint ring 230 and the first restraint ring 229 is internally connected to the air outlet round holes 227. The second restraint ring 230 is higher than the surface of the rotating grinding disc 201.

[0038] In an embodiment of the present invention, during diamond grinding, by starting the air pump 107, the bottom end of the air return cylinder 203 starts to suck air. The absorbed gas flows through the filter element towards the air inlet of the air pump 107, and flows from the air outlet of the air pump 107 into the interior of the air supply box 225. After being sorted by the flow equalizing ring plate 226, it is evenly blown towards the air outlet round holes 227. The airflow blown out from the air outlet round holes 227 is constrained by the first restraint ring 229 and the second restraint ring 230, and then sprayed towards the central axis position of the rotating grinding disc 201 through the annular air gap. With the suction cooperation of the air return cylinder 203, a hood-shaped air wall is formed in the upper area of the rotating grinding disc 201 to constrain the dust and splashing liquid generated during diamond grinding. Part of the dust and splashing liquid droplets are carried by the airflow into the interior of the air return cylinder 203. The gas entering the interior of the air return cylinder 203 flows upward along a spiral trajectory under the guidance of the spiral lifting plate 401. The centrifugal force generated during this process causes some of the liquid droplets and dust carried in the gas to move downward along the surfaces of the air return cylinder 203, the spiral lifting plate 401, and the liquid supply pipe 204 under the action of gravity, and drip onto the surface of the rotating grinding disc 201. Under the centrifugal force generated by the rotation of the rotating grinding disc 201 and being washed by the liquid flowing out from the bottom of the liquid supply pipe 204 or the liquid sprayed by the nozzle group 614, they are washed away from the surface of the rotating grinding disc 201. Among them, the liquid droplets on the inner wall of the air return cylinder 203 are guided by the guide rods 402 to the surface of the liquid supply pipe 204, facilitating the liquid droplets dripping on the surface of the rotating grinding disc 201 to drip at a position near the center of the surface of the rotating grinding disc 201, so that the dripping liquid droplets can be reused more fully; Part of the liquid thrown out by the centrifugal force of the rotating grinding disc 201 directly falls into the area between the second restraint ring 230 and the rotating grinding disc 201 under the restraint of the annular air gap, and part of it impacts on the surface of the second restraint ring 230 and falls into the area between the second restraint ring 230 and the rotating grinding disc 201 under the guidance of the arc-shaped inner wall of the second restraint ring 230. It can be connected to the liquid leakage hole 228 through a pipeline type liquid storage tank, and a filtering device is installed on the pipeline connecting the liquid storage tank and the liquid leakage hole 228 to recycle and reuse the grinding liquid or abrasive.

[0039] The filter element includes: A filter cylinder housing 207 is fixedly connected to the surface of the vertical plate 101. Two shielding blocks 209 are respectively fixedly connected to both ends of the filter cylinder housing 207. A first round rod 210 is arranged between the two shielding blocks 209. The first round rod 210 is rotatably connected to the fourth round grooves formed on the surfaces of the two shielding blocks 209 through two first one-way bearings.

[0040] One of the air hoppers 212 is connected to the interior of the return air cylinder 203 through a pipeline, and the other air hopper 212 is connected to the air inlet of the air pump 107 through a pipeline. A filter adjustment block 213 is arranged in the air hopper 212 connected to the air inlet of the air pump 107 through a pipeline. The filter adjustment block 213 is fixedly connected to a through-hole starting from the surface of the air hopper 212. A sliding block 214 is slidably connected to the interior of the filter adjustment block 213. A return spring 215 is arranged inside the filter adjustment block 213. The two ends of the return spring 215 are respectively fixedly connected to the sliding block 214 and the filter adjustment block 213.

[0041] A plurality of T-shaped round rods 220 are equidistantly fixedly connected to the surface of the adjusting rod 216, a rotating round box 221 is symmetrically arranged on the surface of the T-shaped round rod 220, and the rotating round box 221 is rotatably connected to the T-shaped round rod 220, a torsion spring 224 is arranged inside the rotating round box 221, and the two ends of the torsion spring 224 are respectively fixedly connected to the T-shaped round rod 220 and the corresponding rotating round box 221, and adjusting blocks 222 are symmetrically arranged on both sides of the T-shaped round rod 220, and the adjusting blocks 222 are respectively fixedly connected to the rotating round box 221, a plurality of limit blocks 223 are fixedly connected to the surface of the adjusting rod 216, and the limit blocks 223 conflict with the corresponding adjusting blocks 222, and two groups of passive adjusting blocks 219 are arranged in a circular array at the surface position of the first round rod 210 close to the adjusting rod 216, and the passive adjusting blocks 219 are fixedly connected to the first round rod 210.

[0042] In the embodiment of the present invention, after the gas flows from the inside of the return air cylinder 203 through the pipeline into the inside of the gas bucket 212, the gas is filtered by several filter blocks 208 therein under the shielding effect of the shielding block 209. When the filtering effect of the filter block 208 is gradually reduced due to the blockage of the filter holes, the internal pressure of the gas bucket 212 connected to the air inlet of the air pump 107 decreases. The reduction in the internal pressure of the base 102 causes the sliding block 214 inside the filter adjustment block 213 to overcome the elastic potential energy of the return spring 215 inside the filter adjustment block 213 and move toward the direction close to the central axis of the gas bucket 212. The movement of the sliding block 214 drives the adjustment rod 216 moves on the surface of the supporting round rod 218 in the direction away from the filtering adjustment block 213. During this process, the adjusting block 222, under the resistance of the limit block 223, engages and moves the passive adjusting block 219 on the surface of the first round rod 210 to rotate the first round rod 210. The rotation of the first round rod 210 causes the filter block 208 that is not used due to being blocked by the blocking block 209 to rotate toward the area not blocked by the blocking block 209, thereby improving the overall permeability of the filter block 208 in the filtering operation. When the filter block 208 rotates to the curved opening of the filter cartridge housing 207, the exposed filter block 208 can be taken out and replaced.

[0043] When the internal air pressure of the air bucket 212 connected to the air inlet of the air pump 107 returns to the set value, the sliding block 214 is reset under the action of the elastic potential energy of the reset spring 215. During this process, the first one-way bearing on the surface of the first round rod 210 prevents the first round rod 210 from reversing. Then, under the blocking action of the passive adjustment block 219, the adjustment block 222 drives the rotating round box 221 to rotate around the T-shaped round rod 220 in the direction of overcoming the elastic potential energy of the torsion spring 224, so that the two adjustment blocks 222 rotate around the T-shaped round rod 220 in a direction approaching each other until the two adjustment blocks 222 slide between the two passive adjustment blocks 219 corresponding to the axial direction of the first round rod 210, and the adjustment block 222 that is not in contact with the passive adjustment block 219 rotates around the T-shaped round rod 220 under the action of the elastic potential energy of the torsion spring 224 until it conflicts with the limit block 223.

[0044] It should be noted that the output shaft of the driving motor 202 is fixedly connected to the rotating grinding disc 201 through a reserved hole opened on the surface of the workbench 103.
