Description

Technical Field

[0001] The invention relates to the technical field of record needle processing, in particular to a grinding device used for processing micro-record needles. Background Art

[0002] Micro-record needles usually refer to the needles used to play vinyl records, also called pickup needles. This type of needle is very small, usually around 0.1 mm in diameter, and is usually made of diamond or other hard materials to ensure durability and precision. Compared to digital music carriers, vinyl records have more natural sounds and better restore the essence of music. The function of the pickup needle is to convert the micro-continuous grooves on the surface of the record into analog electrical signals through tiny movements, which are amplified by the subsequent stage and finally expressed in the form of sound.

[0003] At present, the material of the pickup needle is mostly quartz glass or sapphire, which can easily cause wear of the pickup needle after long-term use. Subsequently, a single crystal diamond needle with high wear resistance and high strength was developed. However, due to the high hardness and anisotropy of single crystal diamond and its extremely small size, it is difficult to grind it out. In addition, during the grinding process of the record needle, it is necessary to change the position of the mounting seat of the clamp to adjust the eccentricity of the diamond needle clamp. The prior art mainly relies on screws to fix the mounting seat of the clamp, and the bolts need to be rotated during the adjustment and locking operations. The operation is relatively cumbersome, which not only increases the workload of the relevant staff, but also affects the grinding efficiency of the entire record needle. Therefore, the present application provides a grinding device for micro-record needle processing to meet the needs. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a grinding device for processing micro-disc needles to solve the problem that the existing disc needle grinding equipment has cumbersome operation when adjusting the eccentricity of the diamond needle fixture, which affects the efficiency of the disc needle grinding process.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A grinding device for processing a micro-disc needle comprises a frame and an online detection mechanism, wherein an X-moving axis, a numerical control cabinet and a Y-moving axis are fixedly mounted on the frame, a rotating mechanism is mounted on the outside of the X-moving axis, a grinding spindle is mounted on the Y-moving axis, the online detection mechanism is located between the grinding spindle and the rotating mechanism, a T-shaped fixing seat is sleeved on the end of the rotating mechanism, a fixture mounting seat is fixedly connected to the outside of the T-shaped fixing seat, a record needle fixture is sleeved in the fixture mounting seat, an eccentric adjustment groove matching the shape of the T-shaped fixing seat is opened on the end of the rotating mechanism; an adjustment component is used to adjust the position of the T-shaped fixing seat in the eccentric adjustment groove, and the adjustment component is connected to the rotating mechanism; a positioning component is used to fix the relative position between the T-shaped fixing seat and the eccentric adjustment groove, and the positioning component is connected to the rotating mechanism.

[0007] Optionally, the adjustment assembly includes a rotating rod sleeved in the rotating mechanism, the outside of the rotating rod is fixedly connected to a gear, and one end of the rotating rod extends to the outside of the rotating mechanism and is fixedly connected to a handle, and a movable groove is provided on the outside of the T-shaped fixing seat, and a rack matching the shape of the gear is fixedly connected in the movable groove.

[0008] Optionally, the width of the movable groove is twice the width of the rack, and a through opening penetrating the bottom of the T-shaped fixing seat is formed at the bottom of the movable groove.

[0009] Optionally, the positioning assembly includes an assembly groove opened in the rotating mechanism, a first positioning seat and a second positioning seat are assembled in the assembly groove, the first positioning seat is fixedly connected to the outside with a first positioning block, the second positioning seat is fixedly connected to the outside with a second positioning block, and the first positioning block and the second positioning block are fixedly connected with evenly distributed positioning teeth.

[0010] Optionally, a positioning groove adapted to the shape of the positioning tooth is opened on the back side of the T-shaped fixing seat, the first positioning seat and the second positioning seat are symmetrically distributed in the assembly groove, and the first positioning seat and the second positioning seat are fixedly connected to the inner side wall of the assembly groove by an elastic sheet.

[0011] Optionally, a first extrusion surface is provided at the end of the rotating rod, and a first pressure-bearing groove matching the shape of the first extrusion surface is provided in the first positioning seat.

[0012] Optionally, a sliding area is provided in the middle of the rotating rod, and a second extrusion surface connected to the sliding area is provided on the rotating rod, a second pressure groove adapted to the shape of the second extrusion surface is provided in the second positioning seat, and a limiting opening that can accommodate the passage of the sliding area is provided in the second positioning block.

[0013] Optionally, the first positioning seat and the second positioning seat are both shell structures, the first pressure groove on the first positioning seat and the second pressure groove on the second positioning seat are both facing the handle, the outside of the handle is provided with a groove, and the outside of the handle is provided with evenly distributed friction patterns.

[0014] Optionally, the middle part of the elastic sheet is bent in a C shape, and a weakening groove is provided in the middle part of the elastic sheet. The elastic sheet is connected and fixed to the inner wall of the assembly groove through a connecting end, and the thickness of the connecting end, the elastic sheet and the weakening groove gradually decreases.

[0015] Optionally, an arc-shaped plate is fixedly connected to the outside of the elastic sheet, a support plate is fixedly connected to the end of the arc-shaped plate, and a recess matching the outer shape of the first positioning seat and the second positioning seat is formed on the support plate.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by setting up an adjustment component, the handle can be rotated to drive the adjustment component to work, so that the T-shaped fixing seat produces a corresponding displacement in the eccentric adjustment groove, and then drives the clamp mounting seat and the record needle clamp to move, thereby realizing the eccentric adjustment of the record needle clamp, allowing the grinding equipment to simply and quickly complete the eccentric adjustment of the record needle clamp during operation, which not only reduces the workload of the staff, but also improves the working efficiency of the equipment.

[0018] By setting a positioning assembly and an elastic sheet, when the adjustment assembly is not working, the first positioning seat and the second positioning seat are squeezed by relying on the elastic force of the elastic sheet, so that the positioning teeth outside the first positioning block and the second positioning block can be inserted into the positioning groove on the T-shaped fixing seat, and the T-shaped fixing seat is positioned without the need to use bolt connectors for locking. The positioning can be quickly completed after the adjustment assembly is used, thereby further ensuring the use efficiency of the equipment.

[0019] By setting the sliding area, the second extrusion surface and the first extrusion surface on the rotating rod, when the adjusting component needs to be used for eccentric adjustment, the rotating rod only needs to be pushed into the interior of the rotating mechanism to make the gear and the rack dock, and at the same time, the locking of the T-shaped fixing seat by the positioning tooth is released. At this time, the rotating rotating rod can drive the adjusting component to work for eccentric adjustment. After the adjustment is completed, the rotating rod is reset, and the position of the T-shaped fixing seat can be locked again by the positioning assembly. At this time, the gear and the rack are separated, and the rotating rotating rod will not make the adjusting component work again, so that the structures of the adjusting component and the positioning component are matched with each other. The structure is ingenious, and the two complement each other to form a complete technical solution.

[0020] By providing an elastic sheet, an arc plate and a support plate, the adjustment component can rely on the rotating rod to squeeze the first positioning seat and the second positioning seat to deform the elastic sheet when working, and cause the first positioning seat and the second positioning seat to produce corresponding displacement, so as to release the positioning of the T-shaped fixing seat and allow the T-shaped fixing seat to be eccentrically adjusted. In this process, the elastic sheet is deformed to adapt to the displacement of the first positioning seat and the second positioning seat, and the support plate on the arc plate fits the outside of the first positioning seat and the second positioning seat during the displacement process, providing limitation and support for the first positioning seat and the second positioning seat, so as to ensure the stability of the first positioning seat and the second positioning seat during the displacement process, avoid the phenomenon of misalignment, and further improve the entire technical solution.

After the grinding spindle 6 and the rotating mechanism 3 are adjusted under the action of the Y movable axis 7 and the X movable axis 2, the record needle on the rotating mechanism 3 can be acted upon by the grinding wheel on the grinding spindle 6 for grinding. The online detection mechanism 4 is composed of a lens holder, an XYZ three-axis displacement slide, a coaxial zoom lens, a high-definition color camera, a display, etc.; its main function is to observe the grinding state and conduct online detection of the finished product. The CNC cabinet 5 is used to control the various devices to work according to the preset program to realize the grinding of the record needle. The principles and usage of the X movable axis 2, the rotating mechanism 3, the online detection mechanism 4, the CNC cabinet 5, the grinding spindle 6 and the Y movable axis 7 are the same as those in the prior art and will not be described in detail here.

[0042] The end of the rotating mechanism 3 is sleeved with a T-shaped fixing seat 8, and the outside of the T-shaped fixing seat 8 is fixedly connected with a clamp mounting seat 10, and a record needle clamp 11 is sleeved in the clamp mounting seat 10. An eccentric adjustment groove 9 that matches the shape of the T-shaped fixing seat 8 is opened at the end of the rotating mechanism 3; an adjustment component is used to adjust the position of the T-shaped fixing seat 8 in the eccentric adjustment groove 9, and the adjustment component is connected to the rotating mechanism 3; a positioning component is used to fix the relative position between the T-shaped fixing seat 8 and the eccentric adjustment groove 9, and the positioning component is connected to the rotating mechanism 3. The adjustment component can drive the T-shaped fixing seat 8 to produce displacement in the eccentric adjustment groove 9, and then drive the clamp mounting seat 10 and the record needle clamp 11 to move, so as to achieve the eccentric adjustment of the record needle clamp 11, so that the grinding equipment can simply and quickly complete the eccentric adjustment of the record needle clamp 11 during operation. The positioning component can position the T-shaped fixing seat 8 without the need to use bolt connectors for locking, and can quickly complete the positioning after the adjustment component is used, thereby ensuring the use efficiency of the equipment.

[0043] In this embodiment, if Figures 2 to 7As shown, the adjustment assembly includes a rotating rod 16 sleeved in the rotating mechanism 3, the outside of the rotating rod 16 is fixedly connected to a gear 21, and one end of the rotating rod 16 extends to the outside of the rotating mechanism 3 and is fixedly connected to a handle 12, and a movable groove 20 is opened on the outside of the T-shaped fixing seat 8, and a rack 18 adapted to the shape of the gear 21 is fixedly connected in the movable groove 20. The width of the movable groove 20 is twice the width of the rack 18, and a through hole 35 that penetrates the bottom of the T-shaped fixing seat 8 is opened at the bottom of the movable groove 20. In addition to providing space for the arrangement of the rack 18, the movable groove 20 also provides a storage space for the gear 21 when the adjustment component is not working. When the gear 21 is separated from the rack 18, the gear 21 is stored in the movable groove 20. The through hole 35 at the bottom of the movable groove 20 makes the movable groove 20 connected to the outside of the T-shaped fixing seat 8. When the T-shaped fixing seat 8 is set in the eccentric adjustment groove 9 as a whole, the handle 12 and the rotating rod 16 can be pulled to align the position of the gear 21 with the through hole 35. Correspondingly, it is convenient to assemble the T-shaped fixing seat 8 into the eccentric adjustment groove 9, and the existence of the gear 21 is avoided to prevent the assembly of the T-shaped fixing seat 8. After pushing the handle 12 into the rotating mechanism 3, it can drive the rotating rod 16 to slide in the rotating mechanism 3, and make the gear 21 on the rotating rod 16 engage with the rack 18. At this time, rotating the handle 12 can drive the rotating rod 16, and through the rotation of the gear 21, the rack 18 is pushed to drive the T-shaped fixing seat 8 to move, and finally the T-shaped fixing seat 8 produces corresponding displacement in the eccentric adjustment groove 9, driving the clamp mounting seat 10 and the record needle clamp 11 to move, thereby realizing the eccentric adjustment of the record needle clamp 11.

[0044] In this embodiment, if Figures 3 to 7As shown, the positioning assembly includes an assembly groove 34 opened in the rotating mechanism 3, and the first positioning seat 13 and the second positioning seat 14 are assembled in the assembly groove 34. The assembly groove 34 provides space for the installation of the first positioning seat 13, the second positioning seat 14, and the gear 21 in the rotating mechanism 3, ensures that the first positioning seat 13 and the second positioning seat 14 correspond to the positions of the rotating rod 16, and provides sufficient space for the displacement activities of the first positioning seat 13, the second positioning seat 14 and the gear 21. The first positioning seat 13 is fixedly connected to the outside with a first positioning block 25, and the second positioning seat 14 is fixedly connected to the outside with a second positioning block 28. The first positioning block 25 and the second positioning block 28 are fixedly connected to the first positioning block 25 and the second positioning block 28. Uniformly distributed positioning teeth 26 are fixedly connected. A positioning groove 19 that is compatible with the shape of the positioning tooth 26 is provided on the back side of the T-shaped fixing seat 8. When the T-shaped fixing seat 8 is in a positioned and locked state, the gear 21 is separated from the rack 18, and the positioning teeth 26 outside the first positioning block 25 and the second positioning block 28 are inserted into the positioning groove 19 on the T-shaped fixing seat 8 to position the T-shaped fixing seat 8. The first positioning seat 13 and the second positioning seat 14 are symmetrically distributed in the assembly groove 34, and the first positioning seat 13 and the second positioning seat 14 are fixedly connected to the inner side wall of the assembly groove 34 by an elastic sheet 15. The elastic sheet 15 is a sheet spring steel and can rely on its own elastic force to squeeze and limit the first positioning seat 13 and the second positioning seat 14, so that the first positioning seat 13 and the second positioning seat 14 can maintain a docking and positioning state with the positioning groove 19 when they are not subjected to external forces, thereby maintaining the stability of the T-shaped fixing seat 8 in the locked state.

[0045] In this embodiment, if Figures 3 to 8As shown, the end of the rotating rod 16 is provided with a first extrusion surface 22, and the first positioning seat 13 is provided with a first pressure groove 24 that matches the shape of the first extrusion surface 22. A sliding area 17 is provided in the middle of the rotating rod 16, and a second extrusion surface 23 connected to the sliding area 17 is provided on the rotating rod 16, and a second pressure groove 27 that matches the shape of the second extrusion surface 23 is provided in the second positioning seat 14, and a limiting opening 29 that can accommodate the passage of the sliding area 17 is provided in the second positioning block 28. The limiting opening 29 in the second positioning block 28 is rectangular in the middle, and semicircular on both sides that match the external shape of the sliding area 17. The limiting opening 29 can accommodate the passage of the sliding area 17 on the one hand, and can cooperate with the sliding area 17 to form an auxiliary guide for the second positioning seat 14 during the movement process, further improving the stability of the second positioning seat 14 during the movement process, and when the handle 12 and the rotating rod 16 are pushed into the rotating mechanism 3 The first extrusion surface 22 on the rotating rod 16 squeezes the first pressure groove 24 in the first positioning seat 13, and the second extrusion surface 23 on the rotating rod 16 squeezes the second pressure groove 27 in the second positioning seat 14. The contact area between the first extrusion surface 22 and the first pressure groove 24 and between the second extrusion surface 23 and the second pressure groove 27 decomposes the extrusion force from the rotating rod 16 on the first positioning seat 13 and the second positioning seat 14, forming a thrust away from the rotating rod 16, and then drives the first positioning seat 13 and the second positioning seat 14 to move away from the rotating rod 16, driving the positioning tooth 26 to withdraw from the positioning groove 19, releasing the positioning lock of the T-shaped fixing seat 8, so that the T-shaped fixing seat 8 can be eccentrically adjusted in the eccentric adjustment groove 9.

[0046] In this embodiment, if Figures 9 to 11 As shown, the first positioning seat 13 and the second positioning seat 14 are both shell structures. The shell structures of the first positioning seat 13 and the second positioning seat 14 can reduce the weight of the first positioning seat 13 and the second positioning seat 14 without affecting the overall structural strength of the first positioning seat 13 and the second positioning seat 14, and reduce the material cost of the first positioning seat 13 and the second positioning seat 14. The first pressure groove 24 on the first positioning seat 13 and the second pressure groove 27 on the second positioning seat 14 are both oriented toward the handle 12, and the orientation of the first pressure groove 24 and the second pressure groove 27 is consistent with the first extrusion surface 22 and the second extrusion surface 27 on the rotating rod 16. The directions of the two extrusion surfaces 23 correspond to each other, ensuring that the first extrusion surface 22 and the second extrusion surface 23 can be driven to contact the first pressure groove 24 and the second pressure groove 27 respectively after the rotation rod 16 is displaced. A groove is arranged on the outside of the handle 12, and a uniformly distributed friction pattern is arranged on the outside of the handle 12. The groove on the outside of the handle 12 forms a depression on the outside of the handle 12, forming an uneven structure, which can be convenient for the staff to hold with their hands. The setting of the friction pattern can increase the contact area with the staff's hands, thereby increasing the friction when holding the handle 12, making it easy for the staff to operate the handle 12.

[0047] The middle part of the elastic sheet 15 is bent in a C shape, and a weakening groove 30 is provided in the middle part of the elastic sheet 15. The elastic sheet 15 is connected and fixed to the inner side wall of the assembly groove 34 through a connecting end 31. The thickness values ​​of the connecting end 31, the elastic sheet 15 and the weakening groove 30 gradually decrease. The connecting end 31 is used to connect and fix with the inner side wall of the assembly groove 34, so the thickness value is larger and the strength is higher, so that the stability of the connection and fixation of the elastic sheet 15 is guaranteed. The opening of the weakening groove 30 makes the thickness value of the elastic sheet 15 at this place smaller and the strength is weaker. It is easier to deform at the weakening groove 30 after being subjected to external force. When the adjustment component is working, the first positioning seat 13 and the second positioning seat 14 are The elastic sheet 15 will be displaced and avoid the rotation rod 16 due to the squeezing. During this process, the elastic sheet 15 will follow the displacement of the first positioning seat 13 and the second positioning seat 14, and deform and displace at the weakened groove 30. After the adjustment component is reset, the elastic sheet 15 drives the positioning component to reset by its own elastic force, and locks the T-shaped fixing seat 8 again, so that the adjustment component and the positioning component are matched with each other in structure, and the positioning locking state is immediately released when the adjustment component is working. After the adjustment component is reset, the T-shaped fixing seat 8 is quickly locked, making the operation of the entire eccentric adjustment process simple and efficient, indirectly improving the working efficiency of the entire equipment and shortening the grinding time of the record needle. The outside of the elastic sheet 15 is fixedly connected to an arc plate 32, and the end of the arc plate 32 is fixedly connected to a support plate 33. The support plate 33 is provided with a depression that matches the external shape of the first positioning seat 13 and the second positioning seat 14. During the displacement of the first positioning seat 13 and the second positioning seat 14, the elastic sheet 15 will deform to adapt to the displacement of the first positioning seat 13 and the second positioning seat 14. At this time, the support plate 33 on the arc plate 32 fits the outside of the first positioning seat 13 and the second positioning seat 14 during the displacement of the first positioning seat 13 and the second positioning seat 14, providing limitation and support for the first positioning seat 13 and the second positioning seat 14, so as to ensure the stability of the first positioning seat 13 and the second positioning seat 14 during the displacement process and avoid misalignment.

[0048] The working principle of the technical solution provided by the present invention is as follows: the raw material of the record needle to be processed is placed in the record needle clamp 11 and fixed, the position of the T-shaped fixing seat 8 in the eccentric adjustment groove 9 is adjusted to form an eccentric adjustment of the record needle clamp 11, the handle 12 is held and pushed toward the rotating mechanism 3, the handle 12 drives the rotating rod 16 to slide in the assembly groove 34, and the gear 21 on the rotating rod 16 follows the sliding of the rotating rod 16 and engages with the rack 18 in the movable groove 20.

[0049] During the process of pushing the rotating rod 16 into the rotating mechanism 3, the first extrusion surface 22 and the second extrusion surface 23 on the rotating rod 16 respectively contact the first pressure groove 24 on the first positioning seat 13 and the second pressure groove 27 on the second positioning seat 14, and squeeze the first positioning seat 13 and the second positioning seat 14, so that the first positioning seat 13 and the second positioning seat 14 are displaced in the direction away from the outside of the rotating rod 16, and at the same time, the elastic sheet 15 is bent and deformed at the weakened groove 30, and the first positioning block 25 and the second positioning block 28 move with the displacement of the first positioning seat 13 and the second positioning seat 14, driving the positioning tooth 26 to withdraw from the positioning groove 19, contacting the locking of the T-shaped fixing seat 8, so that the T-shaped fixing seat 8 can be eccentrically adjusted.

[0050] During the deformation of the elastic sheet 15, the support plate 33 on the arc plate 32 maintains contact with the outside of the first positioning seat 13 and the second positioning seat 14, providing guidance and limitation for the displacement of the first positioning seat 13 and the second positioning seat 14, and maintaining the stability of the first positioning seat 13 and the second positioning seat 14 during displacement.

[0051] Turn the handle 12, the handle 12 rotates and drives the rotating rod 16 and the gear 21 to rotate, the gear 21 rotates and pushes the rack 18 to move by the engagement with the rack 18, and then drives the unlocked T-shaped fixing seat 8 to move, the T-shaped fixing seat 8 drives the clamp mounting seat 10 and the record needle clamp 11 to move, so as to form an eccentric adjustment for the record needle clamp 11. After the adjustment is completed, release the handle 12, the first positioning seat 13 and the second positioning seat 14 are reset under the action of the elastic force of the elastic sheet 15, and push the rotating rod 16 and the handle 12 to reset, the positioning tooth 26 docks with the positioning groove 19 again, so as to lock the T-shaped fixing seat 8 and fix the position of the eccentrically adjusted record needle clamp 11.

[0052] After the adjustment is completed, the CNC cabinet 5 is operated to control the X movable axis 2, the rotating mechanism 3, the online detection mechanism 4, the grinding spindle 6, and the Y movable axis 7 to work together to grind the raw material of the record needle fixed at the record needle fixture 11. During the grinding process, continuous monitoring is carried out by relying on the online detection mechanism 4 until the grinding process of the record needle is completed, completing the working process of the entire grinding equipment for processing micro-record needles.
