Description

Technical Field

[0001] The invention relates to the technical field of valve grinding, in particular to a high-precision machine tool for valve grinding and maintenance. Background Art

[0002] Valves are used in various fields of daily life. After long-term use, rust and damage will accumulate inside the valve. In order to ensure the sealing and normal performance of the valve, the valve needs to be polished to restore its surface smoothness.

[0003] When grinding the valve, the presence of rust on the valve surface not only increases the difficulty of grinding, but also significantly prolongs the time required for the entire grinding process. Therefore, before performing the grinding operation, the staff usually pre-treats the valve surface separately to remove part of the rust layer, which makes the pre-treatment work and the subsequent grinding work inconsistent, prolonging the time required for grinding and maintenance work. At the same time, as the grinding wheel grinds, the grinding wheel surface will gradually wear until obvious wear depressions appear. Due to the uncertainty of the grinding wheel wear process, the time when obvious wear depressions appear is also uncertain. The staff is required to check the status of the grinding wheel regularly. Manual inspection increases the staff's work flow. At the same time, due to unexpected situations such as staff negligence, the worn grinding wheel cannot be discovered in time. When using a worn grinding wheel for grinding, the grinding efficiency will be reduced, and the valve surface will also be damaged.

[0004] Therefore, a high-precision machine tool for valve grinding and maintenance is proposed. Summary of the invention

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Following the clamping and positioning process of the valve by the fixed clamping plate, the rust removal liquid inside the rust removal storage tank is quantitatively sprayed on the valve surface, and then the rust removal liquid can soften and remove part of the rust layer, making it easier to remove the rust layer during the grinding process. In addition, two vertically intersecting connecting grooves are arranged, so that in the process of grinding the valve following the downward movement of the grinding wheel body, the liquid sprayed on the valve surface can be switched to the coolant by switching the rotation of the ball shell, and then the switching process of the rust removal liquid and the coolant is carried out synchronously with the fixed grinding action of the valve. Compared with the spraying of the rust removal liquid and the valve grinding as two independent steps in the prior art, the entire valve maintenance and grinding process is more coherent, the operation is simpler, and there is no need for the staff to interfere too much in the grinding process;

[0016] 2. In the process of grinding the valve by moving the grinding wheel body downward, the connection state between the waste liquid tank and the liquid storage tank and the liquid flow groove is switched, so that the coolant can be collected separately according to whether the used coolant contains rust removal liquid. After the grinding is completed, the two coolants are treated separately to avoid the coolant mixing with rust removal liquid and affecting the recycling of the coolant, thereby ensuring the recycling effect of the coolant. At the same time, under the guidance of the inclined surface at the bottom of the liquid flow groove wall, the liquid inside the liquid flow groove can flow toward the collecting hole, so that the liquid inside the liquid flow groove is more easily collected by the waste liquid tank and the liquid storage tank through the collecting hole;

[0017] 3. During the process of the grinding wheel body moving upward and resetting, the resistance of the grinding surface of the grinding wheel body to the detection slide bar makes the second electric contact block electrically contact with the first electric contact block, and whether the second electric contact block arranged in the array is electrically contacted with the first electric contact block at the same time, it is judged whether there is obvious grinding depression on the grinding surface of the grinding wheel body, so that the wear of the valve can be discovered in time, avoiding the need for staff to conduct repeated inspections, preventing the grinding quality of the valve from being reduced due to untimely discovery of the wear of the grinding wheel body, and reducing the possibility of valve damage.

[0047] The above implementation works as follows:

[0048] The initialization steps are as follows:

[0049] The staff injects the rust removal liquid into the rust removal tank 33 and the coolant into the cooling tank 31. In the initial state, the grinding wheel body 27 is located inside the detection block 51, and the two connecting grooves 38 are respectively connected with the rust removal pipe 34 and the connecting nozzle 36. The sliding baffle 314 blocks the connection between the liquid outlet 311 and the rust removal pipe 34. The second piston 411 is located inside a collecting hole 46 below it to block it, and the first piston 410 is located above a collecting hole 46 below it.

[0050] The working steps are as follows:

[0051] The following is a description of the process of using a spray assembly to improve the valve polishing effect:

[0052] like Figures 1 to 10 As shown, after the valve to be polished is placed on the top of the fixed turntable 21, the external drive device of the drive gear 22 is powered on and started, and the external drive device drives the drive gear 22 to start rotating. The rotation of the drive gear 22 drives the two fixed clamping plates 23 meshing with it to slide toward each other inside the fixed turntable 21 and gather together to clamp and fix the valve on the top of the fixed turntable 21. The movement of the fixed clamping plate 23 drives the fixed push block 324 on its top to move toward the sliding bracket 25. The movement of the fixed push block 324 will push the inner wall of the linkage slot frame 323 to push the linkage slot frame 323 to move synchronously with the fixed push block 324. The movement of the linkage slot frame 323 drives the linkage slide rod 318 fixedly connected to it to move synchronously inside the fixed bracket 317 toward the sliding bracket 25. The movement of the linkage slide rod 318 drives the linkage push plate 319 inside it to move synchronously toward the sliding bracket 25. The movement of 19 will resist the linkage push column 315 and push the linkage push column 315 to slide in the sliding push groove 316 toward the liquid outlet 311. The sliding of the linkage push column 315 drives the sliding baffle 314 fixedly connected thereto to slide in the liquid passage groove 312 toward the return spring 313 and compress the return spring 313. At this time, the sliding baffle 314 no longer blocks the connection between the liquid outlet 311 and the rust removal pipe 34. The rust removal liquid in the rust removal storage tank 33 enters the rust removal pipe 34. At this time, the two connecting grooves 38 are respectively connected to the rust removal pipe 34 and the connecting nozzle 36. The rust removal liquid entering the rust removal pipe 34 enters the connecting nozzle 36 through the switching ball shell 37 and is sprayed on the surface of the valve to be polished. Then, the rust removal liquid can soften and remove part of the rust layer, making it easier to remove the rust layer during the grinding process, thereby improving the grinding efficiency and the valve grinding effect.

[0053] When the locking cam 314 is in the unlocking state, the locking cam 314 will be unlocked, and the locking cam 314 will be unlocked when the locking cam 314 is unlocked.

[0054] The following is an explanation of the process of collecting waste liquid by the collection component:

[0055] After the rust removing liquid reacts with the rust on the surface of the valve for a period of time, the sliding bracket 25 slides downward along the surface of the sliding guide rail 24. The downward sliding of the sliding bracket 25 drives the driving motor 26 fixedly connected thereto to move downward. The downward movement of the driving motor 26 drives the grinding wheel body 27 to move downward until the side wall of the grinding wheel body 27 contacts the inner surface of the valve. Then, the driving motor 26 is powered on and started to drive the grinding wheel body 27 to rotate. The side wall of the grinding wheel body 27 rotates and grinds the inner surface of the valve. At the same time, the external driving device 2 of the fixed turntable 21 is powered on and started to drive the fixed turntable 21 to rotate. The rotation of the fixed turntable 21 drives the valve on its top to rotate synchronously, and the grinding wheel body 27 can evenly grind the inner surface of the valve.

[0056] like Figures 4 to 6 As shown, in the process of the sliding bracket 25 moving downward, the downward movement of the sliding bracket 25 drives the starting gear plate 310 fixedly connected thereto to move downward synchronously, and the downward movement of the starting gear plate 310 drives the switching gear 39 meshing therewith to rotate a quarter of a turn, and the rotation of the switching gear 39 drives the switching ball shell 37 fixedly connected thereto to rotate a quarter of a turn inside the connecting ball shell 35. At this time, the two connecting grooves 38 are respectively connected to the cooling through pipe 32 and the connecting nozzle 36. At this time, the coolant inside the cooling storage tank 31 enters the interior of the switching ball shell 37 through the cooling through pipe 32 and is sprayed onto the valve surface by the connecting nozzle 36. At this time, the coolant sprayed on the valve surface can rinse the valve surface, so that the residual rust removal liquid and the loosened and fallen rust residue are separated from the valve surface.

[0057] like Figure 11 to Figure 12As shown in the figure, the coolant mixed with the rust removal liquid and the rust residue enters the interior of the liquid flow groove 41 through the leakage hole 42. Because the side of the bottom of the groove wall of the liquid flow groove 41 away from the waste liquid tank 44 is set as an inclined surface close to the waste liquid tank 44 at the bottom, the coolant entering the liquid flow groove 41 flows along the inclined surface toward the waste liquid tank 44. At the same time, under the interception effect of the fixed filter plate 43, the rust residue in the coolant is blocked at the inclined surface part inside the liquid flow groove 41, and only the liquid enters the interior of the liquid flow groove 41 near the fixed filter plate 43. On the side near the waste liquid tank 44, since the bottom of the liquid flow groove 41 is arranged on both sides close to the waste liquid tank 44 as an inclined surface with the bottom end close to the collecting hole 46, under the guidance of the inclined surface, the liquid gathers in the direction of the collecting hole 46. At this time, the second piston 411 is located inside a collecting hole 46 below it to seal it, and the first piston 410 is located above a collecting hole 46 below it. The coolant of the mixed oil rust removal liquid enters the waste liquid tank 44 through a collecting hole 46 below the first piston 410.

[0058] When the grinding wheel body 27 moves down to the point where it is about to contact the inner surface of the valve, the movement of the sliding bracket 25 drives the linkage pressure plate 412 to contact the top of the switching slide rod 47 and push the switching slide rod 47 to slide downward inside the machine tool body 1 and compress the switching spring 48. The downward sliding of the switching slide rod 47 drives the linkage bracket 49 fixedly connected thereto to move downward inside the liquid flow groove 41. The downward movement of the linkage bracket 49 drives the first piston 410 to move downward into a collecting hole 46 below it to block the collecting hole 46. At the same time, the downward movement of the linkage bracket 49 drives the second piston 411 to move downward and leave a collecting hole 46 below it. The inside of the hole 46, at this time, the liquid storage tank 45 is connected with the inside of the liquid flow channel 41. After the coolant containing only grinding debris enters the liquid flow channel 41 during the grinding process of the grinding wheel body 27, the grinding debris in the coolant is intercepted by the fixed filter plate 43, and the coolant enters the inside of the liquid storage tank 45. Then, according to whether the used coolant contains rust removal liquid, the coolant can be treated separately to avoid the recycling of the coolant due to the mixing of rust removal liquid in the coolant, thereby ensuring the recycling effect of the coolant. At the same time, after the work of the machine tool body 1 is completed, the staff can remove the fixed filter plate 43 to clean the intercepted objects inside the liquid flow channel 41.

[0059] The following is a description of the process for resetting the spray assembly and the collection assembly after grinding is completed:

[0060] like Figures 1 to 10As shown, when the grinding of the grinding wheel body 27 is completed, the fixed turntable 21 stops rotating, the grinding wheel body 27 stops rotating, the fixed push block 324 is still located inside the linkage slot frame 323, and the sliding bracket 25 slides upward along the surface of the sliding guide rail 24. The mutual sliding of the sliding bracket 25 drives the linkage pressure plate 412 fixedly connected thereto to move upward synchronously, and the linkage pressure plate 412 no longer conflicts with the switching slide bar 47. Under the elastic extension action of the switching spring 48, the switching slide bar 47 slides upward inside the machine tool body 1, and the upward sliding of the switching slide bar 47 drives the linkage bracket 49 to move upward inside the liquid flow groove 41. The upward movement of the linkage bracket 49 drives the first piston 410 to leave the interior of a collecting hole 46 below it, and the waste liquid tank 44 is connected to the interior of the liquid flow groove 41. The upward movement of the linkage bracket 49 drives the second piston 411 to move upward into the interior of the collecting hole 46 to block the collecting hole 46, and the liquid storage tank 45 is no longer connected to the interior of the liquid flow groove 41.

[0061] As the sliding bracket 25 continues to slide upward, the sliding of the sliding bracket 25 drives the starting gear plate 310 fixedly connected thereto to move upward, and the upward movement of the starting gear plate 310 drives the switching gear 39 meshing therewith to rotate in the opposite direction by a quarter of a turn, and the rotation of the switching gear 39 drives the switching ball shell 37 fixedly connected thereto to rotate in the opposite direction by a quarter of a turn inside the connecting ball shell 35. At this time, the two connecting grooves 38 are respectively connected to the rust removal pipe 34 and the connecting nozzle 36, and the coolant is no longer sprayed out by the connecting nozzle 36.

[0062] At the same time, the external drive device of the driving gear 22 is powered on and starts to drive the driving gear 22 to rotate in the opposite direction. The opposite rotation of the driving gear 22 drives the two fixed clamping plates 23 meshing with it to slide in the opposite direction inside the fixed turntable 21 and separate from each other. The opposite sliding of the fixed clamping plates 23 drives the fixed push block 324 to move in the opposite direction. The opposite movement of the fixed push block 324 drives the linkage slot frame 323 to move in the opposite direction. The opposite movement of the linkage slot frame 323 drives the linkage slide bar 318 to move in the opposite direction inside the fixed bracket 317. The opposite movement of the linkage slide bar 318 drives the linkage push plate 319 inside it to reset the slot plate 321. The movement of the linkage push plate 319 drives the connecting slide column 320 fixedly connected thereto to move toward the reset groove plate 321. At this time, the connecting slide column 320 is located on the side of the linkage slide rod 318 away from the linkage push column 315, and the movement of the linkage push plate 319 will not interfere with the linkage push column 315. When the connecting slide column 320 moves to the inside of the reset groove plate 321, under the guiding action of the reset groove plate 321, the connecting slide column 320 slides inside the linkage slide rod 318 toward the linkage push column 315. The sliding of the connecting slide column 320 drives the linkage push plate 319 to slide and reset in the direction of the linkage push column 315.

[0063] The following is an explanation of the process of the detection component detecting the grinding surface of the grinding wheel body 27:

[0064] like Fig.13 and Fig.14 As shown, when the grinding wheel body 27 is finished grinding and moves upward to the inside of the detection block 51, the side wall of the grinding wheel body 27 will resist the arc surface of the detection slide bar 53. In the process of the grinding wheel body 27 continuing to move, the side wall of the grinding wheel body 27 pushes the detection slide bar 53 along the arc surface of the detection slide bar 53 to slide inside the detection block 51 toward the first electric contact block 52. The sliding of the detection slide bar 53 drives the second electric contact block 54 fixedly connected thereto to move toward the first electric contact block 52 and stretch the linkage spring 55. When there is no obvious wear and depression on the grinding surface of the side wall of the grinding wheel body 27, the second electric contact block 54 arranged in the annular array Block 54 will be in electrical contact with the first electric contact block 52 at the same time. When the grinding surface of the side wall of the grinding wheel body 27 shows obvious wear and depression, the second electric contact block 54 arranged in the ring array cannot be in electrical contact with the first electric contact block 52 at the same time. When the second electric contact block 54 is not in electrical contact with the first electric contact block 52 at the same time, the external reminder of the machine tool body 1 is activated to remind the staff to replace the grinding wheel body 27, so that the wear of the valve can be discovered in time, avoiding the need for repeated inspections by the staff, preventing the grinding quality of the valve from being reduced due to the untimely discovery of the wear of the grinding wheel body 27, and reducing the possibility of valve damage.

[0065] When the grinding wheel body 27 moves away from the inside of the detection block 51 , the detection slide bar 53 slides and resets inside the detection block 51 under the elastic extension of the linkage spring 55 , and the second electric contact block 54 is separated from the first electric contact block 52 .
