Description

Technical Field

[0001] The invention relates to the technical field of valve processing, in particular to a processing device for a high-temperature quick-opening spherical sealing cut-off valve. Background Art

[0002] A shut-off valve is a valve used to cut off the flow of media in a pipeline. Its main function is to close quickly when needed to prevent the medium from continuing to flow. It is often used in safety protection or emergency shut-off situations. The shut-off valve can be operated manually, electrically, pneumatically, etc., and different types of shut-off valves can be selected according to different application scenarios, such as ball valves, butterfly valves, gate valves, stop valves, etc. The working principle of the shut-off valve is usually based on the closing mechanism of the valve. For example, the ball valve blocks the flow of the medium by rotating the ball, while the butterfly valve achieves the shut-off function by rotating the butterfly plate. In some emergency situations, the shut-off valve can be quickly closed by an automatic control system to prevent accidents.

[0003] A ball valve is a valve that controls opening and closing through a spherical valve core. A through hole is provided on the sphere inside the ball valve to facilitate the flow of the medium. In order to ensure the sealing between the ball and the valve seat, the surface of the ball needs to be polished by a grinder to ensure the roundness and roughness of the surface of the ball valve core.

[0004] A ball valve surface polishing mechanism with publication number CN118990307A belongs to the field of polishing processing technology. The ball valve surface polishing mechanism includes a fixed base, a main driving module is installed on one side of the top of the fixed base, a clamping and fixing module is fixedly installed on the output end of the main driving module, and a top module corresponding to the clamping and fixing module is fixedly installed on the other side of the top of the fixed base; a rotating driving module is fixedly installed on one side of the top of the fixed base close to the main driving module, a polishing module is fixedly installed on the rotating driving module, and a traction module corresponding to the polishing module is installed on one side of the rear end of the top of the fixed base. The above invention can quickly complete the clamping and fixing and disassembly of the ball to be processed by designing the clamping and fixing module, the top module, the polishing module and the traction module. The manual operation only needs to sleeve the ball to be processed on the clamping and fixing module, which not only saves time and effort, but also improves the processing efficiency.

[0005] Although the above patent can quickly clamp and fix the sphere to be processed and disassemble and cut the material, when fine-tuning the sphere, since the inner concave surface does not fit completely with the sphere and the friction between the sphere channel and the rotating clamp arm is large, it is impossible to effectively force the sphere to slide relative to the rotating clamp arm, that is, the sphere cannot be effectively laterally aligned, and thus the grinding effect cannot be guaranteed. At the same time, the particles generated by grinding will be mixed in the grinding liquid and adhere to the surface of the sphere and enter between the sphere and the polishing component, reducing the grinding accuracy. Moreover, after the device has been used for a long time, the bolts fixing the polishing component will loosen due to factors such as vibration or stress, resulting in subtle deviations of the polishing component that are difficult to observe with the naked eye. If it is not discovered in time, it will affect the grinding accuracy.

[0006] Therefore, it is necessary to invent a processing device for a high-temperature quick-opening spherical sealing cut-off valve to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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 creative work are within the scope of protection of the present invention.

[0042] Embodiment 1, the present invention provides as follows Figures 1 to 15 The processing device of a high-temperature quick-opening spherical sealing cut-off valve shown in the figure includes a workbench 1, a receiving tray 2 is fixedly arranged in the middle of the top of the workbench 1, and the receiving tray 2 is used to collect impurities such as grinding liquid and grinding particles dripping during the grinding process; a control console, which is fixedly arranged on one side of the workbench 1 and is electrically connected to the electrical components on the processing device, and is used to control the working state of the electrical components; a sprayer, which is fixedly arranged on the side of the second mounting seat 303, and can spray grinding liquid onto the sphere 4 during the grinding process; the control console and the sprayer are both existing technologies and will not be repeated here.

[0043] It also includes: a driving component 3, which is arranged on one side of the top of the workbench 1 and can drive the ball 4 to rotate.

[0044] Specifically, the driving assembly 3 includes a driving shaft 301, one end of which is fixedly connected to a mounting rod 302; a second mounting seat 303, which is fixedly arranged on the top of the workbench 1; a first driving motor 304, which is fixedly arranged in the second mounting seat 303, and the output end of the first driving motor 304 is coaxially fixedly connected to the driving shaft 301; the first driving motor 304 drives the mounting rod 302 to rotate through the driving shaft 301, so that the mounting rod 302 drives the expansion support assembly 5 thereon to rotate coaxially.

[0045] The expansion component 5 will gradually come into contact with the inner surface of the sphere 4 located outside it when expanding outward, and finally expand and fix the sphere 4, thereby driving the sphere 4 to rotate synchronously with the driving shaft 301.

[0046] Specifically, the expansion support assembly 5 includes a plurality of support rods 501 uniformly arranged on the periphery of the mounting rod 302; a plurality of receiving grooves 502, which are arranged, and the plurality of receiving grooves 502 are uniformly opened on the outer wall of the mounting rod 302; a first slide 503, which is slidably arranged on one side of the inner side of the corresponding receiving groove 502; a first rotating rod 504, one end of which is rotatably connected to the corresponding first sliding seat 503, and the other end is rotatably connected to the corresponding support rod 501; a second sliding seat 505, which is slidably arranged at the bottom of the corresponding support rod 501 and is located on the same side as the corresponding first sliding seat 503; a second rotating rod 506, one end of which is rotatably arranged on the corresponding On the other side of the interior of the accommodating groove 502, the other end is rotatably connected to the corresponding second slide seat 505, and the middle part of the second rotating rod 506 is hinged to the middle part of the corresponding first rotating rod 504; a docking groove 507, which is opened at one end of the mounting rod 302; a push rod 508, one end of which is fixedly connected to the corresponding first slide seat 503; a push ring 509, which is slidably arranged inside the docking groove 507 and is fixedly connected to multiple push rods 508; a reset member is fixedly arranged between the push ring 509 and the bottom of the docking groove 507, so that the push ring 509 is always in a position away from the bottom of the docking groove 507 when it is not subject to external thrust.

[0047] When it is necessary to expand and fix the sphere 4, the sphere 4 is sleeved on the outer periphery of the multiple struts 501, and the push ring 509 is pushed to move toward the bottom of the docking groove 507. The push ring 509 pushes the multiple first slides 503 to slide along the accommodating groove 502 through the push rod 508. At this time, under the hinged action of the first rotating rod 504 and the second rotating rod 506, one end of the second rotating rod 506 rotates in the accommodating groove 502, and the other end drives the second slide 505 to slide along the strut 501, so that the multiple struts 501 are expanded outward synchronously, thereby realizing the expansion, fixation and longitudinal centering of the sphere 4.

[0048] The positioning assembly 6 can be used to position the sphere 4 when it is installed. It includes a sleeve 601, which is slidably arranged on the mounting rod 302. The sleeve 601 can only slide along the mounting rod 302 and will not rotate relative to the mounting rod 302. When the mounting rod 302 rotates, the sleeve 601 will be driven to rotate synchronously; an annular groove 602, which is provided on the outer wall of the sleeve 601; a plurality of rotating wheels 603, which are evenly rotated in the annular groove 602; a plurality of positioning rods 604, which are fixedly arranged on the corresponding rotating wheels 603; the positioning rods 604 can rotate in the annular groove 602 following the rotating wheel 603. When the plurality of positioning rods 604 rotate out of the annular groove 602, the plurality of positioning rods 604 can limit one side of the sphere 4.

[0049] When expanding and fixing the sphere 4, the sphere 4 is first sleeved on the outer periphery of the multiple support rods 501, and one side of the sphere 4 is pressed against the side of the multiple positioning rods 604. At this time, the positioning rods 604 limit the sphere 4 to achieve lateral centering of the sphere 4. When the multiple positioning rods 604 are rotated into the annular groove 602, the positioning rods 604 will no longer contact the sphere 4 and will not interfere with the grinding process.

[0050] The automatic adjustment component 7 is arranged between the expansion component 5 and the positioning component 6. When the expansion component 5 does not expand the sphere 4, the automatic adjustment component 7 can control the positioning component 6 to open. When the expansion component 5 expands the sphere 4, the automatic adjustment component 7 can control the positioning component 6 to close.

[0051] Specifically, the automatic adjustment component 7 includes a first chamber 701, which is opened inside the corresponding support rod 501 and is pre-filled with gas; a piston plate 702, which is slidably arranged inside the corresponding first chamber 701, and a sliding seal is formed between the piston plate 702 and the first chamber 701; a first elastic member 703, which is fixedly arranged on one side of the corresponding piston plate 702; a top rod 704, which is fixedly arranged on the other side of the corresponding piston plate 702, and a top block 715 is fixedly arranged on one end of the top rod 704 located outside the corresponding support rod 501, and the top block 715 can be made of a wear-resistant and non-slip rubber block to increase the friction between it and the ball 4, thereby improving the expansion and fixing effect of the ball 4; a second chamber 705, which is opened inside the sliding sleeve 601, and is connected to each first chamber 701 and is provided with a first conduit 706; a first piston ring 707, which is slidably arranged in the second chamber The first piston ring 707 and the second chamber 705 are slidably sealed inside the sliding sleeve 601, and a connecting rod 709 is fixedly arranged between the sliding ring 708 and the first piston ring 707; an inclined groove 710 is provided on the outer wall of the sliding ring 708, and a plurality of inclined grooves 710 can be evenly arranged; a limiting groove 711 runs through the bottom of the groove provided in the annular groove 602, and the limiting groove 711 is a through groove and communicates with Above the inclined groove 710; a gear ring 712, which is rotatably arranged inside the annular groove 602; a limiting rod 713, which is fixedly arranged on the inner wall of the gear ring 712, and passes through the limiting groove 711 and extends to the inside of the inclined groove 710, and the number and position of the limiting rod 713 remain corresponding to the inclined groove 710; a tooth segment 714, which is fixedly arranged on the corresponding rotating wheel 603, and multiple rotating wheels 603 are meshed with the gear ring 712 through the corresponding tooth segment 714.

[0052] Before the sphere 4 is expanded and fixed, the multiple top blocks 715 are not squeezed by the sphere 4. Under the elastic force of the first elastic member 703, the first chamber 701 and the second chamber 705 are both in the initial state, that is, the first chamber 701 is in the state of maximum space, and the second chamber 705 is in the state of minimum space. The slip ring 708 is completely located inside the sliding sleeve 601. Under the cooperation of the inclined groove 710, the limiting groove 711 and the limiting rod 713, the gear ring 712 forces the multiple positioning rods 604 to be in a mutually open state through the multiple tooth segments 714 and the rotating wheel 603. At this time, the sphere 4 is sleeved on the expansion assembly 5, and one side of the sphere 4 is abutted against one side of the multiple positioning rods 604, thereby limiting the position of the sphere 4.

[0053] After the sphere 4 is abutted against one side of the positioning rod 604, the sphere 4 is expanded and fixed by the expansion assembly 5. During the expansion process of the expansion assembly 5, multiple top blocks 715 are synchronously in contact with the inner wall of the sphere 4 and are squeezed. At this time, the top block 715 will push the piston plate 702 to slide in the first chamber 701 through the top rod 704, the first elastic member 703 is compressed, the space of the first chamber 701 is reduced, and the gas in the first chamber 701 enters the second chamber 705 through the first conduit 706, so that the first piston ring 707 slides in the second chamber 705, and the second chamber The space of chamber 705 increases, and the first piston ring 707 pushes the sliding ring 708 through the connecting rod 709 to gradually extend out of the sliding sleeve 601. At this time, under the cooperation of the inclined groove 710, the limiting groove 711 and the limiting rod 713, the gear ring 712 will rotate synchronously, and drive the multiple rotating wheels 603 to rotate synchronously through the multiple tooth segments 714, so that the multiple positioning rods 604 rotate synchronously into the annular groove 602. When the expansion assembly 5 fully expands and fixes the ball 4, the multiple positioning rods 604 are completely transferred into the annular groove 602, thereby avoiding interference with the grinding process.

[0054] The cleaning component 9 can clean the surface of the sphere 4 during the polishing process, and includes a first telescopic member 901, which is fixedly arranged on the top of the receiving plate 2; a mounting frame 902, which is fixedly arranged on the top of the first telescopic member 901; and a cleaning cotton 903, which is fixedly arranged on the top of the mounting frame 902. During the polishing process of the sphere 4, the first telescopic member 901 is controlled to be extended and retracted so that the cleaning cotton 903 contacts the surface of the sphere 4, absorbs the grinding liquid mixed with grinding particles attached to the surface of the sphere 4, and transfers the grinding liquid mixed with grinding particles to the cleaning cotton 903, so as to ensure the cleanliness of the surface of the sphere 4, avoid the influence of grinding particles on the polishing process, and improve the polishing effect of the sphere 4. In order to ensure that the grinding liquid mixed with grinding particles is smoothly transferred to the cleaning cotton 903, the cleaning cotton 903 can be made of a sponge material with larger gaps.

When the plurality of positioning rods 604 are rotated into the annular groove 602, the plurality of convex blocks 1006 are all located in the corresponding paving grooves; a fixing frame 1007, one end of which is fixedly connected to the second mounting seat 303; a clamping rod 1008, one end of which is fixedly connected to the rotating sleeve 1 002 is fixedly connected, and the other end is slidably connected to the fixing frame 1007. The clamping rod 1008 cooperates with the fixing frame 1007 so that the rotating sleeve 1002 can only move laterally with the sliding sleeve 601 but will not rotate; the sliding groove 1009 is opened through the top of the mounting frame 902; there are two trapezoidal sliders 1010, which are symmetrically slidably arranged inside the sliding groove 1009; the squeezing plate 1011 is fixedly arranged on the top of the corresponding trapezoidal slider 1010, and the cleaning cotton 903 is located between the two squeezing plates 1011; the guide frame 1012 is fixedly arranged in the middle of the mounting frame 902, and the guide frame 1012 is a hollow structure; the strip slider 1013 The two ends are respectively slidably engaged with the trapezoidal slider 1010 on the same side, wedge blocks are provided at both ends of the strip slider 1013, and a wedge groove is provided on the trapezoidal slider 1010. The wedge blocks and the wedge groove cooperate with each other, so that the strip slider 1013 and the trapezoidal slider 1010 will not be disengaged from each other while sliding relative to each other, and the middle part of the strip slider 1013 is placed inside the guide frame 1012; the expansion part 1014 is arranged inside the guide frame 1012 and placed above the strip slider 1013, and a second conduit 1015 is provided between the expansion part 1014 and the third chamber 1004; the second elastic member 1016 is arranged inside the guide frame 1012 and placed below the strip slider 1013.

[0056] During the grinding process of the sphere 4, the plurality of positioning rods 604 are all rotated into the annular groove 602 and rotate synchronously with the sleeve 601. When the plurality of protrusions 1006 rotate toward the raised portion of the annular boss 1005, the annular boss 1005 drives the second piston ring 1003 to slide along the extension ring 1001 in the direction away from the protrusion 1006, so that the space of the third chamber 1004 is reduced, and the gas in the third chamber 1004 will enter the expansion portion 1014 through the second conduit 1015. The expansion portion 1014 expands, thereby pushing the strip slider 1013 to slide downward along the guide frame 1012, and the second elastic member 1016 is compressed. At the same time, the strip slider 1013 pulls the two trapezoidal sliders 1010 closer to each other, so that the two squeezing plates 1011 squeeze the cleaning cotton 903 located in the middle thereof, so as to squeeze out and collect the grinding liquid mixed with grinding particles in the cleaning cotton 903. To the receiving plate 2; when the multiple protrusions 1006 rotate toward the recessed part of the annular boss 1005, the multiple protrusions 1006 no longer squeeze the annular boss 1005. At this time, under the elastic force of the second elastic member 1016, the strip slider 1013 slides upward along the guide frame 1012, and the two squeezing plates 1011 no longer squeeze the cleaning cotton 903. The expansion portion 1014 is reduced in volume under the upward thrust, and the gas inside it enters the third chamber 1004 through the second conduit 1015. The space of the third chamber 1004 increases, and the second piston ring 1003 slides along the extension ring 1001 in the direction close to the protrusion 1006 and returns to its initial state; as the sleeve 601 continues to rotate, the two squeezing plates 1011 repeatedly and intermittently squeeze out the grinding liquid mixed with grinding particles in the cleaning cotton 903, thereby ensuring the cleaning ability of the cleaning cotton 903 on the sphere 4.

[0057] The push-up assembly 11 is arranged on the other side of the top of the workbench 1, and the push-up assembly 11 includes a first mounting seat 1101, which is fixedly arranged on the top of the workbench 1; a second telescopic member 1102, which is fixedly arranged on the first mounting seat 1101, and the second telescopic member 1102 and the driving shaft 301 are on the same central axis; a push-up sleeve 1103, which is rotatably arranged on the movable end of the second telescopic member 1102, and the diameter of the push-up sleeve 1103 matches the inner diameter of the docking groove 507; by controlling the extension of the second telescopic member 1102, the push-up sleeve 1103 is extended into the docking groove 507 and the push ring 509 is pushed to move toward the bottom of the docking groove 507, so that the multiple support rods 501 are synchronously expanded outward to realize the expansion operation.

[0058] The grinding assembly 8 can grind the sphere 4, and includes a swing frame 801, which is rotatably arranged on the top of the workbench 1; a second drive motor 802, which is fixedly arranged inside the workbench 1, and the output shaft of the second drive motor 802 is fixedly connected to the swing frame 801, and the second drive motor 802 is a forward and reverse motor, which can drive the swing frame 801 to swing repeatedly continuously; two swing arms 803, which are provided and symmetrically arranged on both sides of the top of the swing frame 801; two shaft rods 804, which are provided and slidably arranged on the corresponding swing arms 803, respectively, the two shaft rods 804 are on the same central axis, and the central axis of the two shaft rods 804 and the central axis of the drive shaft 301 are located in the same plane; a third telescopic member 805, which is fixedly arranged on the opposite The top of the swing arm 803 should be fixedly connected with the corresponding shaft rod 804 at its movable end; the third drive motor 806 is fixedly arranged at the bottom of the corresponding shaft rod 804; the rotating shaft 807 is coaxially rotatably arranged inside the corresponding shaft rod 804, and one end is transmission-connected with the corresponding third drive motor 806, and the other end extends to the outside of the corresponding shaft rod 804, and is fixedly provided with a mounting plate, and the two mounting plates are rotatably arranged at one end of the two shaft rods 804 close to each other through bearings; there are two grinding discs 808, which are detachably mounted on the corresponding mounting discs through bolts respectively, and the grinding disc 808 should be coaxially arranged with the rotating shaft 807 when being installed, and the two grinding discs 808 cooperate with each other to grind the sphere 4 located in the middle.

[0059] When grinding the sphere 4, the third telescopic member 805 is controlled to drive the shaft 804 to extend, so that the two grinding discs 808 are completely fitted with the sphere 4, and then the third drive motor 806 is rotated through the rotating shaft 807, so that the two grinding discs 808 grind the sphere 4. During the grinding process, the second drive motor 802 drives the swing frame 801 to swing repeatedly, so that the two grinding discs 808 can rotate around the rotation axis of the third drive motor 806 while repeatedly swinging around the rotation axis of the second drive motor 802, thereby achieving all-round grinding of the sphere 4 and ensuring the grinding effect of the sphere 4.

[0060] The distance adjustment component 12 includes a threaded section 1201, which is arranged on the driving shaft 301; a threaded sleeve 1202, which is threadedly connected to the threaded section 1201; a connecting frame 1203, one end of which is rotatably connected to the threaded sleeve 1202, and the other end is fixedly connected to the sliding sleeve 601; when grinding spheres 4 of different sizes, the position of the positioning rod 604 needs to be adaptively adjusted to achieve lateral centering of the sphere 4. At this time, the threaded sleeve 1202 is rotated so that the threaded sleeve 1202 drives the sliding sleeve 601 to move laterally along the mounting rod 302 through the connecting frame 1203, thereby achieving the adjustment of the position of the positioning rod 604, so that it can limit the spheres 4 of different sizes.

[0061] In summary, when grinding the sphere 4, firstly, the position of the positioning assembly 6 is adjusted by the distance adjustment assembly 12 according to the size of the sphere 4, then the sphere 4 is sleeved on the expansion assembly 5, and one side of the sphere 4 is abutted against the plurality of positioning rods 604, and then the abutment assembly 11 is controlled to extend, so that the expansion assembly 5 expands and fixes the sphere 4, and while the sphere 4 is being expanded and fixed, the automatic adjustment assembly 7 forces the plurality of positioning rods 604 to automatically rotate into the annular groove 602, and then the grinding disc 80 is adjusted. 8 is positioned so that the two grinding discs 808 are completely fitted with the surface of the sphere 4, and the driving component 3 and the grinding component 8 are started. The driving component 3 drives the sphere 4 to rotate, and the grinding component 8 drives the grinding discs 808 to rotate and swing, so as to perform all-round grinding on the sphere 4. During the grinding process, the cleaning component 9 absorbs the grinding liquid mixed with grinding particles on the surface of the sphere 4. At the same time, the extrusion component 10 repeatedly and intermittently squeezes the cleaning cotton 903 to squeeze out the grinding liquid mixed with grinding particles inside and collect it into the receiving tray 2.

[0062] By the coordinated use of the expansion component 5, the positioning component 6 and the automatic adjustment component 7, before the expansion component 5 expands and fixes the sphere 4, the positioning component 6 can limit the sphere 4 to achieve lateral centering of the sphere 4, and then the sphere 4 is expanded and fixed by the expansion component 5 to achieve longitudinal centering of the sphere 4. Through the above operations, all-round centering and expansion and fixation of the sphere 4 are achieved, thereby ensuring that the grinding disc 808 can fully fit with the sphere 4, thereby improving the grinding accuracy and effect of the sphere 4; and, in the process of the expansion component 5 expanding and fixing the sphere 4, the automatic adjustment component 7 will cause the multiple positioning rods 604 to automatically rotate into the annular groove 602, thereby avoiding interference with the grinding process and ensuring the smooth progress of the grinding work.

[0063] By using the cleaning component 9 and the extrusion component 10 in coordination, the cleaning component 9 can absorb the grinding liquid mixed with grinding particles attached to the surface of the sphere 4 during the grinding process into the cleaning cotton 903, so as to ensure the cleanliness of the surface of the sphere 4, prevent the grinding particles from entering between the sphere 4 and the grinding disk 808, prevent the grinding process from being affected, and improve the grinding effect and accuracy of the sphere 4. The extrusion component 10 can repeatedly and intermittently squeeze the cleaning cotton 903, so as to squeeze the grinding liquid mixed with grinding particles out of the cleaning cotton 903 and collect it into the receiving plate 2, thereby ensuring that the cleaning cotton 903 can always maintain its ability to absorb the grinding liquid and improve the cleaning ability of the cleaning cotton 903 on the surface of the sphere 4.

[0064] Embodiment 2: In the above embodiment, the sphere 4 is laterally aligned by the positioning assembly 6, and the sphere 4 is longitudinally aligned by the expansion assembly 5, so as to realize the all-round alignment and expansion fixation of the sphere 4, and ensure that the sphere 4 can be completely fitted with the grinding disc 808 during the grinding process. However, it is found in the actual grinding process that since the grinding disc 808 is detachably mounted on the rotating shaft 807 by bolts, after the device has been used for a long time, the bolts will loosen due to factors such as vibration or stress, and the position of the grinding disc 808 will change slightly, and the grinding disc 808 will no longer remain on the same axis with the rotating shaft 807, resulting in that even after the sphere 4 is omnidirectionally aligned, the sphere 4 and the grinding disc 808 still cannot be completely fitted, affecting the grinding accuracy and effect of the sphere 4. However, since the position change of the grinding disc 808 is relatively subtle, it is difficult for the staff to judge whether the grinding disc 808 is displaced by naked eye observation. Therefore, based on the above problems, the scheme of the present invention is further improved.

[0065] Specifically, Figures 16 to 18 As shown, the positioning rod 604 includes: a first rod body 6041, which is fixedly arranged on the corresponding rotating wheel 603; a second rod body 6042, which is rotatably connected to the first rod body 6041 through a hinge 6045, and connecting ears 6043 are fixedly arranged on the first rod body 6041 and the second rod body 6042; and a tension spring 6044, which is fixedly arranged between the two corresponding connecting ears 6043.

[0066] It should be noted that the hinge 6045 is a limit hinge. When it is flipped outward to the maximum angle, it will no longer be able to continue flipping, thereby limiting the maximum flipping angle of the second rod body 6042. This is a prior art and will not be described in detail here. Colorant can be applied to the protrusion 1006 to facilitate printing of the movement trajectory at the front edge of the grinding disc 808.

[0067] In the initial state, the first rod 6041 and the second rod 6042 are located in the same plane, and the tension spring 6044 provides tension between the two. The ends of the first rod 6041 and the second rod 6042 that are close to each other are completely fitted and docked, so that the first rod 6041 and the second rod 6042 are always in the same plane. Fig.16 The state shown in the figure, at this time, the positioning rod 604 can normally limit the ball 4; the second rod 6042 follows the hinge 6045 to rotate to the maximum angle, so that the first rod 6041 and the second rod 6042 are in a bent state as a whole, and the tension spring 6044 provides tension for both, and the first rod 6041 and the second rod 6042 are limited in the bent state, as shown in the figure. Fig.17 Status shown.

[0068] In summary, before grinding the ball 4, the second rod 6042 is first rotated to the maximum angle following the hinge 6045. At this time, the tension provided by the tension spring 6044 limits the first rod 6041 and the second rod 6042 to the position as shown in FIG. Fig.17 Then, the colorant is applied to the protrusion 1006, and the position of the grinding disc 808 is adjusted by the third telescopic member 805 so that the edge of the grinding disc 808 contacts the protrusion 1006, as shown in FIG. Fig.18 In the state shown, the grinding disc 808 is then driven to rotate by the rotating shaft 807. During this process, the movement trajectory of the protrusion 1006 relative to the grinding disc 808 will be printed on the edge of the grinding disc 808 through the colorant. The staff determines whether the grinding disc 808 is displaced by observing the printed colorant traces. If the printed colorant traces are regular and continuous circles, and the distances between each point of the circular trajectory and the edge of the grinding disc 808 are equidistant, it means that the grinding disc 808 is not displaced, and the subsequent grinding process can be carried out normally. If the printed colorant traces are not regular and continuous circles, or the distances between each point of the circular trajectory and the edge of the grinding disc 808 are not equal, it means that the grinding disc 808 has been displaced, and the staff needs to adjust and tighten the grinding disc 808 in time.

[0069] By using the first rod 6041, the second rod 6042, the tension spring 6044, the hinge 6045, the protrusion 1006 and the grinding disc 808 in coordination, when the first rod 6041 and the second rod 6042 are adjusted to be in the same plane, the sphere 4 can be normally limited; when the first rod 6041 and the second rod 6042 are adjusted to a bent state and colorant is applied to the protrusion 1006, a motion trajectory can be printed at the edge of the rotating grinding disc 808, and by observing whether the printed trajectory is a regular and continuous circle or whether the distances between each point of the circular trajectory and the edge of the grinding disc 808 are equidistant, a quick and intuitive judgment can be made as to whether the grinding disc 808 is displaced, thereby avoiding grinding processing when the grinding disc 808 is displaced, preventing the production of defective products due to the displacement of the grinding disc 808, and improving the yield rate of grinding processing.
