[0003] When the existing glass polishing equipment processes the glass, the glass is placed in a placement groove of a fixture, and then the fixture rotates, and the polishing disk also rotates synchronously to achieve the polishing operation of the glass.

[0004] Existing jigs are usually fixed on polishing equipment, that is, the existing polishing equipment is mainly used to process glass of the same specifications and shapes. When other shapes of glass need to be processed, the corresponding equipment needs to be replaced. Common polishing equipment is mainly used to polish round or square glass. When special shaped glass needs to be processed, new corresponding equipment needs to be manufactured, which is costly. That is, the existing processing equipment is not very applicable and cannot adapt to the polishing of glass of different shapes. Summary of the invention

[0005] In order to improve the applicability of glass sheet processing equipment, the present application provides a processing device and process for a space radiation-resistant micro-ceramic glass cover plate.

[0006] The present application provides a space radiation-resistant microcrystalline glass cover plate processing device and process using the following technical solutions: A processing device for a space radiation-resistant microcrystalline glass cover plate comprises a machine body, on which a plurality of supporting plates are rotatably arranged, the plurality of supporting plates are distributed in a circular array, an inner concave annular groove is provided in the supporting plate, a jig disk is placed in the inner concave annular groove, and the jig disk is plugged and matched with the inner concave annular groove, a placement groove adapted to the shape of the glass sheet is provided on the jig disk, a polishing disk is lifted and lowered on the machine body, and the rotation trajectory of the edge of the polishing disk passes through the center of the jig disk; a gear ring is formed on the outer peripheral side of the jig disk, a sliding groove is provided in the supporting plate, a locking tooth is slidably provided in the sliding groove, and the locking tooth meshes with the gear ring to achieve locking of the supporting plate.

[0007] By adopting the above technical scheme, the jig disc is placed into the concave annular groove of the supporting plate, and then the special-shaped glass cover plate is placed into the placement groove. Then, the engagement of the locking teeth with the gear ring can prevent the jig disc from rotating in the concave annular groove. Then, the polishing disc descends and abuts against the glass cover plate. Then, the supporting plate and the polishing disc rotate synchronously and in opposite directions to achieve the polishing operation of the glass cover plate. The locking of the jig disc by the locking teeth can prevent the jig disc from rotating with the polishing disc during the polishing process, thereby preventing the polishing effect of the glass cover plate from being affected. Since the jig disc and the supporting plate can be detachably connected by plug-in cooperation, when it is necessary to process glass of different shapes, it is only necessary to replace the suitable jig disc without replacing the equipment.

After that, the vacuum pump is operated to evacuate air, thereby forming negative pressure adsorption at the adsorption hole, so that the glass cover plate is adsorbed and fixed, thereby ensuring the stability of the glass cover plate during the polishing process.

[0011] By adopting the above technical solution, the driving member drives the driving wheel to rotate. When the driving wheel rotates, it drives the connecting rod to move, and the connecting rod drives the sliding block to slide in the sliding groove, so that the locking tooth engages with the gear ring on the fixture disk, thereby limiting the rotation of the fixture disk.

When the sliding block slides to make the locking tooth and the gear ring mesh, the first wedge-shaped surface drives the jig disk to move downward through the second wedge-shaped surface; the supporting plate is located in the middle of the concave annular groove and is provided with an abutment platform, the upper end of the connecting shaft is penetrated by the abutment platform and the upper end of the connecting shaft is flush with the surface of the abutment platform, the supporting plate is located on the peripheral side of the abutment platform and is lifted and slid with a lifting platform, the supporting plate is located on the bottom wall of the concave annular groove and is installed with a compression spring, the upper end of the compression spring is connected to the lifting platform, and in the initial state, the lifting platform is higher than the abutment platform; a boss is circumferentially arranged at the edge of the abutment platform, and a rubber pad is embedded in the jig disk on the peripheral side of the first connecting hole, and the position of the rubber pad corresponds to the position of the boss.

[0015] By adopting the above technical solution, in the initial state, the jig disc is overlapped on the lifting platform, at this time the jig disc is not in contact with the abutment platform, when the sliding block slides, the locking tooth gradually meshes with the gear ring, and under the action of the first wedge surface and the second wedge surface, the jig disc will drop, at this time the lifting platform drops and compresses the compression spring until the jig disc abuts with the abutment platform, the sliding block cannot move, at this time the locking tooth and the gear ring are meshed, the jig disc cannot rotate, under the cooperation of the first wedge surface and the second wedge surface, the jig disc cannot rise, that is, the jig disc is fixed, and the stability of the jig disc during the polishing process is improved; when the jig disc abuts with the abutment platform, at this time the boss abuts with the rubber pad, and because the boss is higher than the abutment platform, the rubber pad is deformed, at this time because the rubber pad is squeezed at the boss, the extrusion point has good sealing, thereby ensuring the sealing between the jig disc and the abutment platform, which helps to ensure the stability of subsequent negative pressure adsorption.

[0016] Preferably, a screw slide is installed on the machine body in the vertical direction, a mounting plate is installed on the slide of the screw slide, a first motor is installed in the mounting plate, a first pulley is coaxially fixed on the output shaft of the first motor, a rotating rod is rotatably connected in the mounting plate, a second pulley is coaxially fixed on the rotating rod, belts are wound around the first pulley and the second pulley, and the polishing disc is coaxially fixed to the lower end of the rotating rod.

[0017] By adopting the above technical solution, the screw slide realizes the lifting and lowering of the mounting plate, that is, the lifting and lowering of the polishing disc; the first motor runs to drive the first pulley to rotate, the first pulley drives the second pulley to rotate through the belt, and the second pulley realizes the rotation of the polishing disc through the rotating rod.

[0019] By adopting the above technical solution, the second motor runs, driving the driving gear to rotate, and the driving gear synchronously drives all the driven gears to rotate, thereby realizing the rotation of all the supporting plates.

[0020] Preferably, a linkage rack is formed on the outer wall of the jig disk in the vertical direction, and a linkage gear is rotatably connected to the support plate. When the jig disk is placed into the inner concave ring groove of the support plate, the linkage rack meshes with the linkage gear. A driven rack is also provided in the support plate which slides in the vertical direction, and the driven rack meshes with the linkage gear. A locking rod is fixedly connected to the lower end of the driven rack, and a locking groove is provided on the sliding block, and the locking rod slides in cooperation with the locking groove.

[0021] By adopting the above technical solution, in the initial state, the locking rod and the locking groove are plugged into each other to lock the sliding of the sliding block, that is, the sliding block cannot slide at this time; when the fixture disk is placed on the lifting platform, the lifting platform will drop a short distance due to gravity, and when the fixture disk drops, the linkage rack will drive the linkage gear to rotate, and the linkage gear will drive the driven gear to rise, so that the locking rod is disengaged from the sliding block, and then the sliding block can slide outward; in the initial state, the sliding block can be prevented from sliding by the cooperation of the locking rod and the locking groove, that is, when the fixture disk is not placed, the sliding block will not slide outward due to accidental touching of the hand driving rod or other reasons such as vibration, which will cause the fixture disk to fail to cooperate smoothly with the locking tooth when the fixture disk is placed later.

[0022] Preferably, a sliding groove is provided on the outer wall of the fixture disk, the fixture disk is located in the sliding groove and is slidably connected with a moving block, two wedge blocks are symmetrically arranged on the moving block, the linkage rack is arranged between the two wedge blocks, the fixture disk is located in the sliding groove and is provided with a return spring, one end of the return spring is connected to the moving block, and the other end of the return spring is connected to the inner wall of the sliding groove, and the upper and lower sides of the wedge block are formed with a third wedge surface, and in the initial state, under the action of the return spring, the wedge block extends out of the sliding groove to protrude the fixture The surface of the disk; the support plate is provided with a mounting groove on the inner wall of the concave annular groove, the linkage gear is rotatably connected in the mounting groove, and abutment parts are formed on both sides of the mounting groove on the linkage gear, and the two wedge blocks and the two abutment parts correspond to each other one by one and abut with each other; a fourth wedge-shaped surface is formed at the upper opening of the mounting groove; the upper port diameter of the second connecting hole is larger than the lower port diameter of the first connecting hole; a lifting port is provided on the side of the fixture disk, and when the fixture disk is driven by gravity to lower the lifting platform, the lifting port is covered by the support plate.

[0023] By adopting the above technical solution, the jig disc is placed in the concave annular groove. When the wedge block contacts the supporting plate, the moving block slides into the sliding groove under the action of the third wedge surface. At this time, the jig disc can smoothly enter the concave annular groove. When the two wedge blocks are completely entered into the installation groove at the same time, the moving block slides outward under the action of the reset spring. At this time, the wedge block abuts against the abutting part, and the linkage rack meshes with the linkage gear. Then, due to the gravity of the jig disc, the linkage rack drives the driven gear to rise through the linkage gear to unlock the sliding block. When the jig disc needs to be replaced, the sliding block slides and disengages from the jig disc. Then Under the action of the compression spring, the lifting platform drives the fixture disk to rise a certain distance, and then the vacuum pump reverses and blows. At this time, the high-pressure gas will act on the lower end of the fixture disk. Because the upper port diameter of the second connecting hole is larger than the lower port diameter of the first connecting hole, the high-pressure gas will generate an upward force on the fixture disk. With the help of the compression spring, the fixture disk continues to rise for a distance, so that the lifting port is exposed, which is convenient for the staff to take the fixture disk out of the concave ring groove through the lifting port. When the fixture disk slides upward, the third wedge surface on the upper side of the wedge block cooperates with the fourth wedge surface, and the moving block slides into the sliding groove to ensure the smooth removal of the fixture disk.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The fixture plate and the supporting plate are detachably connected. When polishing of glass of different shapes is required, only the corresponding fixture plate needs to be replaced without directly replacing the equipment. That is, the polishing equipment of the present application has strong applicability; 2. The locking teeth cooperate with the gear ring on the jig disc to limit the rotation of the jig disc, so as to prevent the jig disc from rotating with the polishing wheel during the polishing process, thereby affecting the polishing effect of the glass cover plate. In addition, in the process of the locking teeth and the gear ring gradually cooperating, the jig disc can be lowered and tightly abutted against the abutment platform under the action of the first wedge surface and the second wedge surface, thereby ensuring the sealing of the connection between the first connecting hole and the second connecting hole, and thus ensuring the stability of negative pressure adsorption; 3. When the jig tray is placed on the lifting platform, the lifting platform will drop a certain distance due to the gravity of the jig tray. At this time, the linkage rack on the outer wall of the lifting platform drives the driven rack to slide through the linkage gear, and the driven rack slides upward, so that the locking rod is disengaged from the locking groove on the sliding block, and the lock of the sliding block is released. At this time, the sliding block can slide. After the jig tray is taken out, the lifting platform will rise due to the compression spring. At this time, the locking rod will drop and plug into the locking groove to limit the sliding block to prevent the sliding block from sliding outward due to accidental touch, which will cause the subsequent jig tray to fail to descend.

[0031] Through the detachable connection between the jig tray 3 and the supporting plate 2, when it is necessary to process glass of different shapes, it is only necessary to replace the adapted jig tray 3 without replacing the equipment, that is, the processing device of the present application has strong applicability.

[0032] Reference Figure 2 and Figure 3 A screw slide 12 is installed on the machine body 1 in the vertical direction, a mounting plate 4 is fixedly installed on the slide of the screw slide 12, a first motor 41 is installed in the mounting plate 4, a first pulley 42 is coaxially fixed on the output shaft of the first motor 41, a rotating rod 43 is rotatably connected in the mounting plate 4, a second pulley 44 is coaxially fixed on the rotating rod 43, a belt 45 is wound around the first pulley 42 and the second pulley 44, and the polishing disc 11 is coaxially fixed to the lower end of the rotating rod 43.

[0033] Reference Figure 2 , Figure 4 and Figure 5 A concave annular groove 21 is provided on the supporting plate 2, and the jig disc 3 is plugged into the concave annular groove 21. The supporting plate 2 is integrally formed with an abutment platform 22 in the middle of the concave annular groove 21. After the jig disc 3 is placed in the concave annular groove 21, the bottom of the jig disc 3 abuts against the abutment platform 22.

The supporting plate 2 is located in the sliding groove 5 and is provided with a sliding block 51 for sliding. The sliding block 51 is integrally formed with a locking tooth 52 at one end close to the concave annular groove 21. A gear ring 32 is embedded in the outer peripheral side of the jig disc 3. When the locking tooth 52 slides outward, it meshes with the gear ring 32, thereby limiting the jig disc 3 and preventing the jig disc 3 from rotating during the polishing process, thereby affecting the polishing effect of the special-shaped glass.

[0034] Reference Figure 4 and Figure 6A connecting shaft 6 is rotatably connected inside the supporting plate 2, and a driving wheel 61 is coaxially fixed on the connecting shaft 6. Two connecting rods 611 are hinged on the driving wheel 61. The hinge points of the connecting rods 611 and the driving wheel 61 are eccentrically arranged with the center of the driving wheel 61. The two connecting rods 611 correspond to the two sliding blocks 51 one by one. One end of the connecting rod 611 away from the driving wheel 61 is hinged to the sliding block 51, and a driving member for driving the driving wheel 61 to rotate is arranged in the supporting plate 2.

[0035] The driving member drives the driving wheel 61 to rotate, and the driving wheel 61 drives the connecting rod 611 to move, and the connecting rod 611 can drive the sliding block 51 to slide, and the two sliding blocks 51 can slide toward each other to engage with the gear ring 32 on the fixture disk 3 to achieve locking of the rotation of the fixture disk 3.

A plug-in slot 71 is provided in the worm 7 to be plugged and matched with the plug-in block 81, that is, the hand-driven rod 8 rotates coaxially with the worm 7 and the two can slide relative to each other. When the staff drives the hand-driven rod 8 to rotate, the hand-driven rod 8 drives the worm 7 to rotate, and the worm 7 can realize the rotation of the driving wheel 61 through the worm wheel 62.

[0037] Reference Figure 2 , Figure 4 and Figure 7 A suction hole 311 is provided on the bottom wall of the fixture plate 3 located at the placement groove 31. A vacuum negative pressure is generated at the suction hole 311 to adsorb and fix the special-shaped glass. A first connecting hole 33 is provided in the fixture plate 3. The first connecting hole 33 is connected to all the adsorption holes 311. A second connecting hole 23 is provided in the supporting plate 2. In fact, the second connecting hole 23 is vertically penetrated in the connecting shaft 6. The upper end of the connecting shaft 6 is penetrated by the abutment platform 22, and the upper end of the connecting shaft 6 is flush with the surface of the abutment platform 22. A vacuum pump 13 is installed in the machine body 1, and the vacuum port of the vacuum pump 13 is connected to the lower end of the second connecting hole 23 through a rotary joint. The jig plate 3 is placed in the supporting plate 2. When the jig plate 3 abuts against the abutment platform 22, the first connecting hole 33 and the second connecting hole 23 are connected. Then the glass cover plate is placed in the placement groove 31 of the jig plate 3. The vacuum pump 13 is operated to evacuate air, thereby forming negative pressure adsorption at the adsorption hole 311, so that the glass cover plate is adsorbed and fixed, thereby ensuring the stability of the glass cover plate during the polishing process.

[0038] Reference Figure 4 , Figure 5 and Figure 8The sliding block 51 is located on the upper side of the locking tooth 52 and is also formed with a first wedge surface 53. The fixture plate 3 is located on the upper side of the gear ring 32 and is formed with a second wedge surface 321. When the sliding block 51 slides, the locking tooth 52 gradually meshes with the gear ring 32. During the meshing process, the first wedge surface 53 and the second wedge surface 321 abut and cooperate, so that the fixture plate 3 moves downward. The support plate 2 is located on the peripheral side of the abutment platform 22 and is lifted and slid with a lifting platform 24. The support plate 2 is located on the bottom wall of the inner concave annular groove 21 and is installed with a compression spring 25. The compression spring 25 is vertically arranged, and the upper end of the compression spring 25 is connected to the lifting platform 24. In the initial state, under the action of the compression spring 25, the lifting platform 24 is higher than the abutment platform 22.

The bottom wall of the fixture plate 3 is located around the first connection hole 33 and is embedded with a rubber pad 34 . The position of the rubber pad 34 corresponds to that of the boss 221 .

[0039] The jig disc 3 is placed on the lifting platform 24. At this time, the jig disc 3 is not in contact with the abutment platform 22. Under the action of gravity, the lifting platform 24 descends a certain distance, and then the bottom of the jig disc 3 will contact the boss 221. Then the sliding block 51 slides outward, and the locking tooth 52 engages with the gear ring 32. With the cooperation of the first wedge surface 53 and the second wedge surface 321, the jig disc 3 continues to descend until the jig disc 3 abuts against the abutment platform 22. At this time, the locking tooth 52 engages with the gear ring 32, and the jig disc 3 cannot rotate or rise, thereby realizing the limit locking of the jig disc 3. At this time, the surface of the jig disc 3 is flush with the surface of the supporting plate 2. Because the boss 221 is higher than the abutment platform 22, when the fixture plate 3 abuts against the abutment platform 22, the boss 221 will squeeze the rubber pad 34 to cause a concave deformation, and the rubber pad 34 at the squeezed position will be tightly wrapped around the side of the boss 221, thereby ensuring the sealing between the fixture plate 3 and the abutment platform 22, thereby ensuring the stability of negative pressure adsorption.

[0040] Reference Figure 2 and Figure 7 The machine body 1 is provided with a receiving groove 9, and the machine body 1 is provided with a second motor 91 in the receiving groove 9. A driving gear 911 is coaxially fixed on the output shaft of the second motor 91. The lower side of the supporting plate 2 extends into the receiving groove 9. A driven gear 26 is coaxially fixed on the lower end of the supporting plate 2. The driving gear 911 is meshed with all the driven gears 26. The second motor 91 is running, driving the driving gear 911 to rotate, and the driving gear 911 synchronously drives all the driven gears 26 to rotate, thereby realizing the synchronous rotation of all the supporting plates 2.

[0041] The implementation principle of a processing device for a space radiation-resistant microcrystalline glass cover plate in the embodiment of the present application is as follows: the jig plate 3 is placed into the inner concave annular groove 21 of the supporting plate 2, the jig plate 3 is first located on the lifting platform 24, and then due to gravity, the lifting platform 24 descends, and the jig plate 3 abuts against the boss 221, and then the staff rotates the hand-driven rod 8, the driving wheel 61 rotates, so that the sliding block 51 slides, the locking tooth 52 gradually meshes with the gear ring 32, and under the cooperation of the first wedge surface 53 and the second wedge surface 321, the jig plate 3 continues to descend until it abuts against the abutment platform 22, at this time The jig plate 3 cannot rotate or rise and fall; then the irregular-shaped glass cover plate is placed in the placement groove 31 of the jig plate 3, and the vacuum pump 13 is operated to generate negative pressure at the adsorption hole 311 to adsorb and fix the glass cover plate, and then the polishing plate 11 descends to contact the glass piece, and finally the first motor 41 and the second motor 91 are operated, and the polishing plate 11 and the supporting plate 2 are rotated to realize the polishing operation of the glass piece; when it is necessary to process glass of different shapes, it is only necessary to replace the corresponding jig plate 3, and there is no need to replace the equipment, which reduces the cost, that is, the processing device of the present application has strong applicability.

[0042] Example 2 Reference Fig. 9 The difference between this embodiment and the embodiment 1 is that a limiting groove 27 is provided on the inner wall of the inner concave annular groove 21 of the support plate 2 in the vertical direction, and the support plate 2 is rotatably connected with the linkage gear 10 in the limiting groove 27, and a linkage rack 35 is fixedly installed on the outer wall of the fixture plate 3 in the vertical direction. When the fixture plate 3 is placed on the lifting platform 24, the linkage rack 35 meshes with the linkage gear 10. A driven rack 28 is also slidable in the support plate 2 in the vertical direction, and the driven rack 28 meshes with the linkage gear 10, and the driven rack 28 is located on the side of the linkage gear 10 away from the linkage rack 35. A locking rod 281 is fixedly connected to the lower end of the driven rack 28, and a locking groove 511 is provided on the sliding block 51 in the vertical direction. In the initial state, the locking rod 281 is plugged into and matched with the locking groove 511 to lock the sliding block 51 to prevent the sliding block 51 from accidentally sliding out of the sliding groove 5 and affecting the installation of the fixture plate 3.

[0043] When the fixture plate 3 is placed on the lifting platform 24, the lifting platform 24 drops a short distance due to gravity. At this time, the linkage rack 35 drives the linkage gear 10 to rotate, and the driven rack 28 also rises accordingly. The locking rod 281 is disengaged from the locking groove 511, and the lock on the sliding block 51 is released, and then the sliding block 51 can slide.

[0044] When the fixture plate 3 is placed into the supporting plate 2, the linkage rack 35 will be plugged into the limiting groove 27 to limit the rotation of the fixture plate 3. Therefore, in this embodiment, the locking tooth 52 and the gear ring 32 do not need to be matched.

[0045] Example 3 Reference Fig.10 , Fig.11 and Fig.12 The difference between this embodiment and embodiment 2 is that a sliding groove 20 is provided on the outer wall of the fixture disk 3, and the fixture disk 3 is located in the sliding groove 20 and is slidably connected with a moving block 201. Two wedge blocks 202 are integrally formed on the moving block 201. The two wedge blocks 202 are symmetrically arranged, and the linkage rack 35 is fixed between the two wedge blocks 202. The fixture disk 3 is located in the sliding groove 20 and is installed with a return spring 203. One end of the return spring 203 is connected to the moving block 201, and the other end of the return spring 203 is connected to the inner wall of the sliding groove 20. The upper and lower sides of the wedge block 202 are formed with a third wedge surface 204. In the initial state, under the action of the return spring 203, the wedge block 202 extends out of the sliding groove 20 and protrudes from the surface of the fixture disk 3.

[0046] The support plate 2 is not provided with a limit groove 27, and a mounting groove 29 is provided on the inner wall of the support plate 2 located at the inner concave annular groove 21, and the linkage gear 10 is rotatably connected in the mounting groove 29. The mounting groove 29 is located on both sides of the linkage gear 10 and has abutment parts 291 formed thereon, and the two wedge blocks 202 and the two abutment parts 291 correspond to each other and abut and cooperate with each other; a fourth wedge surface 292 is formed at the opening of the mounting groove 29. A lifting opening 36 is provided on the side of the fixture plate 3 to facilitate the removal of the fixture plate 3.

[0047] The jig plate 3 is placed into the concave annular groove 21. When the wedge block 202 contacts the notch of the concave annular groove 21 of the supporting plate 2, the moving block 201 slides into the sliding groove 20 under the action of the third wedge surface 204, and the jig plate 3 smoothly enters the concave annular groove 21. When the two wedge blocks 202 completely enter the installation groove 29 at the same time, the return spring 203 acts, and the moving block 201 slides outward. At this time, the wedge block 202 and the abutment portion 291 The linkage rack 35 is in contact with the linkage gear 10 at this time, and then under the action of gravity, the linkage rack 35 drives the driven gear 26 to rise through the linkage gear 10, and the locking rod 281 is disengaged from the locking groove 511, thereby unlocking the sliding block 51, and at this time the lifting mouth 36 is covered by the supporting plate 2; then the sliding block 51 slides under the action of the first wedge surface 53 and the second wedge surface 321, and the fixture plate 3 descends and abuts against the abutment table 22. When the jig plate 3 needs to be replaced, the sliding block 51 slides and disengages from the jig plate 3. Under the action of the compression spring 25 and the deformation reset of the rubber pad 34, the lifting platform 24 drives the jig plate 3 to rise a certain distance, and the jig plate 3 is disengaged from the abutment platform 22, that is, the first connecting hole 33 and the second connecting hole 23 are separated. The vacuum pump 13 is turned over and air is blown. The upper port diameter of the second connecting hole 23 is larger than the lower port diameter of the first connecting hole 33. Therefore, the blown high-pressure gas will drive the jig plate 3 to move upward again for a certain distance, and the pulling port 36 is exposed outside the supporting plate 2. The worker can easily remove the jig plate 3 from the inner concave annular groove 21. During the removal process, the third wedge surface 204 on the upper side of the wedge block 202 cooperates with the fourth wedge surface 292, and the moving block 201 slides into the sliding groove 20 to ensure that the jig plate 3 is smoothly removed.

[0048] Since the wedge block 202 will enter the installation groove 29, the rotation of the fixture plate 3 is locked under the cooperation of the installation groove 29 and the wedge block 202. Therefore, in this embodiment, the cooperation between the locking teeth 52 and the gear ring 32 is not required.

[0049] In this embodiment, in order to ensure that the wedge block 202 enters the installation groove 29 smoothly, a calibration line can be set at the opening of the concave ring groove 21 of the support plate 2 and the surface of the fixture plate 3 to ensure that the wedge block 202 and the installation groove 29 will not be misaligned when the fixture plate 3 is inserted into the concave ring groove 21.
