Description

Technical Field

[0001] This application relates to the field of grinding equipment technology, and in particular to a surface grinding equipment for ceramic tube shells. Background Technology

[0002] Ceramic housings are encapsulation shells made from ceramic raw materials. They feature high airtightness, high thermal conductivity, and high mechanical strength, and are widely used for the encapsulation and protection of electronic components. To ensure the processing accuracy of electronic components, the two ends of the ceramic housings need to be ground to ensure dimensional accuracy and surface roughness. Therefore, a grinding machine for batch grinding of ceramic housings needs to be designed.

[0003] Chinese Patent CN212859037U discloses a double-sided grinding machine, which includes a frame, a bottom grinding device, and a top grinding device. The bottom grinding device includes a lower grinding disc, planetary gears, a sun gear, and a bottom drive mechanism connected to the lower grinding disc, and includes a bottom drive motor. The top grinding device includes a lifting mechanism, an upper grinding disc, and a top drive mechanism, which includes a top drive motor. In use, both the upper and lower surfaces of the workpiece can be ground and polished, greatly improving the processing efficiency of the double-sided grinding machine. The planetary gears and the upper grinding disc can be controlled to rotate at different speeds by the bottom drive mechanism and the top drive mechanism respectively, thus improving the applicability of the double-sided grinding machine. By changing the speeds of the bottom drive motor and the top drive motor, the rotation speeds of the lower and upper grinding discs can be changed respectively, resulting in different grinding effects.

[0004] Regarding the aforementioned technologies, existing technologies utilize planetary gears to constrain the ceramic tube shell and simultaneously grind both ends of the ceramic tube shell using an upper and lower grinding disc, thus achieving the grinding process of the ceramic tube shell. However, with prolonged use, the grinding areas of the upper and lower grinding discs will wear down, easily forming local grooves, and the degree of wear varies in different parts, which can easily reduce the grinding accuracy of the ceramic tube shell and reduce the grinding effect of the grinding equipment. Summary of the Invention

[0005] In order to improve the grinding effect of grinding equipment, this application provides a surface grinding equipment for ceramic tube shell parts.

[0006] This application provides a surface grinding equipment for ceramic tube shells, employing the following technical solution:

[0007] A surface grinding device for ceramic tube shells includes a machine body, an inner rotary table, an outer rotary table, an upper grinding disc, a lower grinding disc, and a hydraulic cylinder. The inner and outer rotary tables are rotatably connected to the machine body. The hydraulic cylinder is vertically mounted on the machine body, and its output end is rotatably connected to an end cap. The upper grinding disc is connected to the end cap, and the lower grinding disc is connected to the outer rotary table. A plurality of toothed columns are circumferentially connected to the surfaces of the outer and inner rotary tables. The lower grinding disc is located between two rings of toothed columns. A dressing assembly is provided on the machine body. The dressing assembly includes a mounting frame, a tool holder, and a dressing tool. The mounting frame is detachably connected to the machine body and covers the toothed columns of the outer rotary table. The machine has several detachable tool holders on the mounting frame. Each dressing tool is vertically mounted on the tool holder and radially arranged. The dressing tool abuts against the lower grinding disc and covers the grinding area of ​​the lower grinding disc along its length. The end cover is equipped with a linkage component that is linked to the inner turntable. During dressing, the mounting frame is mounted on the machine body, the dressing tool is mounted on the tool holder, and the tool holder is mounted on the mounting frame, causing the dressing tool to abut against the lower grinding disc. A hydraulic cylinder lowers the end cover, causing the upper grinding disc to lower and abut against the top of the dressing tool. The inner and outer turntables rotate relative to each other, and the linkage component rotates the end cover. The bottom of the dressing tool dresses the surface of the lower grinding disc, and the top of the dressing tool dresses the surface of the upper grinding disc.

[0008] By adopting the above technical solution, during the dressing process, the mounting frame is installed on the machine body, the dressing blade is mounted on the blade holder, and the blade holder is mounted on the mounting frame, so that the dressing blade contacts the lower grinding disc. A hydraulic cylinder drives the end cover to descend, causing the upper grinding disc to descend and contact the tip of the dressing blade. The inner and outer turntables rotate relative to each other, and the linkage drives the end cover to rotate. The bottom of the dressing blade dresses the surface of the lower grinding disc, and the top of the dressing blade dresses the surface of the upper grinding disc, achieving the effect of dressing both the upper and lower grinding discs. By mounting the dressing blade on the machine body, in conjunction with the upper and lower grinding discs rotating in opposite directions, the dressing blade can dress both the upper and lower grinding discs in one step, reducing the possibility of grooves on the surfaces of the upper and lower grinding discs, ensuring the flatness of the grinding areas of the upper and lower grinding discs, and improving the grinding effect of the grinding equipment.

[0009] Optionally, a supporting frustum is provided on the inner turntable, and a plurality of first balls are embedded at the bottom end of the supporting frustum. The first balls abut against the inner turntable, and the tool holder is detachably connected between the mounting frame and the supporting frustum.

[0010] By adopting the above technical solution, the tool holder is connected to the mounting frame at only one end. When the upper and lower grinding discs apply pressure to the dressing tool, there is a possibility of vibration at the other end of the tool holder, affecting the dressing accuracy of the upper and lower grinding discs. By setting a supporting frustum, the stability of the other end of the tool holder is improved, reducing the possibility of dressing tool vibration and ensuring the dressing accuracy of the upper and lower grinding discs.

[0011] Optionally, the machine body is connected to a mounting cylinder, the mounting frame has an L-shaped cross-section and is configured as two semicircles, the two mounting frames forming a complete circle, the mounting frame is detachably connected to the mounting cylinder, both ends of the tool holder are connected to extension plates, the mounting frame and the support circular platform are each connected to two stabilizing columns, the stabilizing columns are vertically arranged, the extension plates are sleeved between the two stabilizing columns, the stabilizing columns are provided with stabilizing components to stabilize the tool holder, and the outer turntable and the mounting frame are provided with a support member to assist in supporting the mounting frame.

[0012] By adopting the above technical solution, when installing the tool holder, the extension plate is fitted onto the stabilizing post, and then the stabilizing components are used to restrict the extension plate, thus realizing the installation of the tool holder. The stabilizing post serves to improve the stability of the tool holder and to limit the installation direction of the tool holder, while the support components are used to improve the stability of the mounting frame on the mounting cylinder.

[0013] Optionally, the stabilizing component includes a mounting block, an adjusting screw, a pressure spring, and a pressure plate. The mounting block is detachably connected to the stabilizing column. The adjusting screw is vertically threaded onto the mounting block. The pressure plate is sleeved on the bottom end of the adjusting screw and abuts against the extension plate. The pressure spring is disposed between the pressure plate and the bottom end of the adjusting screw. Gaps are provided between the extension plate and the mounting frame, and between the extension plate and the supporting frustum.

[0014] By adopting the above technical solution, when stabilizing the extension plate, the extension plate is sleeved on the stabilizing column, and then the mounting block is installed on the stabilizing column. The adjusting screw is rotated to lower the adjusting screw, which drives the pressure table to lower until the pressure table presses the extension plate tightly. The pressure spring is compressed. At this time, the dressing knife abuts against the lower grinding disc, and a gap is left between the extension plate and the mounting frame, thus realizing the installation of the tool holder.

[0015] Optionally, the mounting block is provided with a limiting component, which includes a locking arc block, a connecting rod, a return spring, and a push plate. A moving groove is formed in the mounting block at the position corresponding to the stabilizing column. The locking arc block slides within the moving groove. Two locking arc blocks are arranged opposite each other. An abutting arc surface is provided on the inner ring wall of the locking arc block, with the reference direction from bottom to top. The thickness of the locking arc block gradually increases. A locking ring groove is formed on the stabilizing column at the position corresponding to the moving groove. Several connecting rods are connected to the locking arc blocks. The connecting rods slide within the mounting block and extend to the outside of the mounting block. A retaining ring is connected to the connecting rod and is located within the moving groove. The push plate is connected to several of the connecting rods and is located outside the mounting block. The return spring is sleeved on the connecting rod and is located between the mounting block and the push plate. When limited, the locking arc block abuts against the inner top wall of the locking ring groove, and the retaining ring abuts against the inner wall of the moving groove.

[0016] By adopting the above technical solution, during installation, the mounting block is placed on the stabilizing column. During this process, the stabilizing column touches the abutting arc surface, causing the locking arc block to move. The return spring is compressed until the locking ring groove is flush with the moving groove. The locking arc block then moves in the opposite direction under the force of the return spring and enters the locking ring groove, driving the connecting rod to move until the retaining ring abuts against the inner wall of the moving groove. This restricts the degree of freedom of the mounting block. At the same time, the reaction force of the extension plate applied by the pressure spring is used to improve the stability of the mounting block, thus realizing the installation of the mounting block. During removal, the push plate is applied to move the connecting rod, driving the locking arc block to move and disengage from the locking ring groove. At this time, the mounting block can be removed from the stabilizing column, achieving the effect of removing the mounting block.

[0017] Optionally, the support member is a support column, and several support members are provided. A second ball bearing is embedded at the bottom end of the support member. The second ball bearing abuts against the outer turntable. A stabilizing arc plate is also connected to the inner top wall of the mounting frame. The mounting cylinder is located between the mounting frame and the stabilizing arc plate.

[0018] By adopting the above technical solution, the stability of the mounting frame on the mounting cylinder is improved through the cooperation of the mounting frame and the stabilizing arc plate. Subsequently, the support stability of the mounting frame near the toothed column is further improved through the cooperation of the support column and the second ball bearing.

[0019] Optionally, the mounting frame is provided with a mounting assembly, which includes a limiting frame, a pressing post, and a locking post. Several stabilizing plates are connected to the inner ring wall of the mounting cylinder. The limiting frame is connected to the stabilizing plates and has two limiting teeth that are arranged opposite to each other. The pressing post slides vertically on the mounting frame. The locking post is horizontally connected to the bottom end of the pressing post and is located inside the limiting frame. The two limiting teeth abut against the locking post. A pull ring is connected to the top of the pressing post and abuts against the mounting frame.

[0020] By adopting the above technical solution, when locking the mounting frame, the mounting frame is placed on the mounting cylinder, and then pressure is applied to the pressing column to lower the locking column until it enters the limiting frame. During this process, the locking column abuts against the limiting teeth, causing the limiting frame to deform. After the locking column passes the limiting teeth, the limiting teeth return to their original position. At this time, the pull ring abuts against the top wall of the mounting frame, thereby limiting the degree of freedom of the mounting frame on the mounting cylinder and realizing the installation of the mounting frame.

[0021] Optionally, the pressing column is provided with an auxiliary disassembly assembly, which includes a rotating cylinder, a rotating plate, and a top column. The rotating cylinder is sleeved on the pressing column, the rotating plate is connected to the top of the rotating cylinder and is located between the pull ring and the mounting frame, and the top column is connected to one of the two limiting teeth on the surface of the rotating cylinder.

[0022] By adopting the above technical solution, when dismantling the installation frame, rotating the rotating plate drives the rotating cylinder to rotate, causing the top column to rotate. During this process, the top column applies pressure to the limiting teeth, causing the limiting teeth to deform. At this time, pulling the pull ring can raise the locking column and disengage it from the limiting frame, thus achieving the effect of dismantling the installation frame.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. During the dressing process, the mounting frame is installed on the machine body, the dressing blade is mounted on the blade holder, and the blade holder is mounted on the mounting frame, so that the dressing blade contacts the lower grinding disc. A hydraulic cylinder lowers the end cover, causing the lower grinding disc to descend and contact the tip of the dressing blade. The inner and outer turntables rotate relative to each other, and the linkage drives the end cover to rotate. The bottom of the dressing blade dresses the surface of the lower grinding disc, and the top of the blade dresses the surface of the upper grinding disc, achieving the effect of dressing both the upper and lower grinding discs. By mounting the dressing blade on the machine body, and cooperating with the upper and lower grinding discs rotating in opposite directions, the dressing blade can dress both the upper and lower grinding discs in one step, reducing the possibility of grooves on the surfaces of the upper and lower grinding discs, ensuring the flatness of the grinding areas of the upper and lower grinding discs, and improving the grinding effect of the grinding equipment.

[0025] 2. During installation, the mounting block is placed on the stabilizing post. During this process, the stabilizing post contacts the abutting arc surface, causing the locking arc block to move. The return spring is compressed until the locking ring groove is flush with the moving groove. The locking arc block then moves in the opposite direction under the force of the return spring and enters the locking ring groove, driving the connecting rod to move until the retaining ring abuts against the inner wall of the moving groove. This restricts the freedom of the mounting block. Simultaneously, the reaction force of the extension plate applied by the pressure spring is used to improve the stability of the mounting block, thus achieving installation. During removal, the push plate is applied, causing the connecting rod to move, which in turn moves the locking arc block and disengages it from the locking ring groove. At this point, the mounting block can be removed from the stabilizing post, achieving the effect of removing the mounting block.

[0026] 3. When locking the mounting frame, place the mounting frame onto the mounting cylinder, then apply pressure to the locking pin, causing it to descend until it enters the limiting frame. During this process, the locking pin contacts the limiting teeth, causing the limiting frame to deform. As the locking pin passes the limiting teeth, the limiting teeth return to their original position. At this point, the pull ring contacts the top wall of the mounting frame, thus limiting the freedom of the mounting frame on the mounting cylinder and achieving the installation of the mounting frame.

[0040] Reference Figure 2 The hydraulic cylinder 16 is vertically mounted on the machine body 1. The end cover 15 is rotatably connected to the output shaft of the hydraulic cylinder 16. The upper grinding disc 13 is mounted on the end cover 15 at the position corresponding to the lower grinding disc 14. The end cover 15 is provided with a linkage 151, which is a hexagonal prism. A hexagonal groove is opened at the center of the inner turntable 11. During grinding, the linkage 151 is inserted into the hexagonal groove.

[0041] During grinding, several planetary gears 18 are placed between the two rings of toothed columns 17, and a ceramic tube shell is placed in the placement hole. Then, the hydraulic cylinder 16 is activated to lower the end cover 15 until the upper grinding disc 13 touches the ceramic tube shell. The linkage 151 is inserted into the hexagonal slot, and the inner motor 111 and the outer motor 121 are activated. The inner turntable 11 and the outer turntable 12 rotate relative to each other, so that the lower grinding disc 14 grinds the bottom end of the ceramic tube shell and the upper grinding disc 13 grinds the top end of the ceramic tube shell, thus achieving the effect of simultaneous grinding of both ends of the ceramic tube shell.

[0042] Reference Figure 3 , Figure 4 and Figure 5 The machine body 1 is equipped with a trimming assembly 2, which includes a mounting frame 21, a tool holder 22, and a trimming tool 23. A mounting cylinder 19 is fixedly connected to the machine body 1, surrounding the outer turntable 12. Two mounting frames 21 are semi-circular, forming a complete circle. A stabilizing arc plate 211 is integrally formed on each mounting frame 21, and the mounting frame 21 is fitted onto the mounting cylinder 19 via the stabilizing arc plate 211. Several support members 212 are provided on the inner top wall of the mounting frame 21. Each support member 212 is a support column, vertically positioned, and has a second ball bearing embedded at its bottom end, which abuts against the outer turntable 12.

[0043] Reference Figure 4 and Figure 6 The mounting frame 21 is provided with a mounting component 3, which includes a limiting frame 31, a pressing post 32, and a locking post 33.

[0044] Reference Figure 4 and Figure 6 A pressing post 32 is vertically inserted into the mounting frame 21, and a locking post 33 is horizontally fixedly connected to the bottom end of the pressing post 32. A pull ring 321 is fixedly connected to the top end of the pressing post 32. An auxiliary disassembly assembly 4 is provided on the pressing post 32, which includes a rotating cylinder 41, a rotating plate 42, and a top post 43. The rotating cylinder 41 is inserted into the mounting frame 21 and fitted onto the pressing post 32. The rotating plate 42 is hexagonal and fixedly connected to the top end of the rotating cylinder 41, located between the pull ring 321 and the mounting frame 21. Two top posts 43 are horizontally fixedly connected to the bottom end of the rotating cylinder 41.

[0045] The mounting frame 21 is fitted onto the mounting cylinder 19, and then pressure is applied to the pressing column 32 to lower the locking column 33 until it enters the limiting frame 31. During this process, the locking column 33 presses against the limiting tooth 311, the limiting frame 31 deforms, the limiting tooth 311 moves, the locking column 33 passes through the limiting tooth 311, and the limiting tooth 311 returns to its original position. At this time, the rotating plate 42 is pressed against the pull ring 321 and the mounting frame 21 to realize the installation of the mounting frame 21. When disassembling, the rotating plate 42 is rotated with a tool to drive the rotating sleeve to rotate, so that the top column 43 presses against the limiting tooth 311, the limiting frame 31 deforms, and the limiting tooth 311 moves. At this time, the pull ring 321 can be pulled to disengage the locking column 33 from the limiting tooth 311, and the mounting frame 21 can be removed.

[0046] Reference Figure 3 , Figure 7 and Figure 8 An inner rotary table 11 is provided with a supporting frustum 112. Several first ball bearings are embedded circumferentially at the bottom end of the supporting frustum 112, and the first ball bearings abut against the inner rotary table 11. The tool holder 22 is U-shaped and several are arranged between the mounting frame 21 and the supporting frustum 112. In this embodiment, three are used as an example. Two fixing plates are arranged in the middle of the tool holder 22. The dressing tool 23 is vertically arranged between the two fixing plates and is fixedly connected to the fixing plates by a pin. The dressing tool 23 is arranged radially with the inner rotary table 11 as the axis, and its length direction covers the grinding area of ​​the lower grinding disc 14.

[0047] Reference Figure 7 and Figure 9 Both ends of the tool holder 22 are fixedly connected with horizontally arranged extension plates 221. The mounting frame 21 and the supporting frustum 112 are both fixedly connected with two vertically arranged stabilizing columns 222 at the positions corresponding to the extension plates 221. The extension plates 221 are fitted onto the stabilizing columns 222. The dressing tool 23 abuts against the lower grinding disc 14. Gaps are left between one extension plate 221 and the mounting frame 21 and between the other extension plate 221 and the supporting frustum 112.

[0048] Reference Figure 9 and Figure 10A stabilizing component 5 is provided on the stabilizing column 222. The stabilizing component 5 includes a mounting block 51, an adjusting screw 52, ​​a pressure spring 53, and a pressure table 54. The mounting block 51 is welded from two welding blocks and has two mounting holes through which the stabilizing column 222 passes. A limiting component 6 is provided on the mounting block 51, which includes a locking arc block 61, a connecting rod 62, a return spring 63, and a push plate 64. The mounting block 51 has a moving groove, with two moving grooves arranged opposite each other and communicating with the corresponding mounting holes. The locking arc block 61 is located in the moving groove, and its inner ring wall has an abutting arc surface 611. The thickness of the locking arc block 61 gradually increases from bottom to top as a reference direction. Two limiting rods are fixedly connected to the locking arc block 61, and the locking arc block 61 slides with the mounting block 51 through the limiting rods.

[0049] Reference Figure 9 and Figure 10 Several connecting rods 62 are fixedly connected to the locking arc block 61. In this embodiment, two rods are used as an example. The connecting rods 62 pass through the mounting block 51 and extend to the outside of the mounting block 51. A retaining ring 621 is fixedly connected to the connecting rod 62 and is located in the moving groove. The push plate 64 is fixedly connected between the two connecting rods 62. The pressure spring 53 is sleeved on the connecting rod 62 and is located between the mounting block 51 and the push plate 64. The stabilizing column 222 has a locking ring groove 2221 at the position corresponding to the moving groove.

[0050] Reference Figure 9 The adjusting screw 52 passes vertically through the mounting block 51 and is threaded into the mounting block 51. The pressure table 54 is rotatably connected to the bottom end of the adjusting screw 52. The pressure spring 53 is disposed between the pressure table 54 and the bottom end of the adjusting screw 52.

[0051] When installing the tool holder 22, the extension plates 221 at both ends of the tool holder 22 are fitted between the two corresponding stabilizing posts 222. The dressing tool 23 abuts against the lower grinding disc 14. Then, the mounting block 51 is fitted onto the stabilizing post 222. During this process, the top of the stabilizing post 222 applies pressure to the arc surface 611, causing the locking arc block 61 to move. The return spring 63 is compressed until the locking ring groove 2221 aligns with the moving groove. The locking arc block 61 moves in the opposite direction under the force of the return spring 63 and enters the locking ring groove 2221 until the retaining ring 621 abuts against the inner side wall of the moving groove, thereby restricting the mounting block 51. Then, the adjusting screw 52 is rotated to lower the adjusting screw 52, ​​which drives the pressure table 54 to lower. The pressure spring 53 is compressed, thereby restricting the extension plate 221, thus realizing the installation of the tool holder 22.

[0052] The implementation principle of the ceramic tube shell surface grinding equipment in this application embodiment is as follows: When installing the dressing cutter 23, the mounting frame 21 is sleeved on the mounting cylinder 19, the second ball abuts against the outer turntable 12, and then pressure is applied to the pressing column 32, causing the locking column 33 to descend until it enters the limiting frame 31. At this time, the rotating plate 42 abuts against the pull ring 321 and the mounting frame 21 to realize the installation of the mounting frame 21. Then, the supporting frustum 112 is placed on the inner turntable 11, and the extension plate 221 on the cutter holder 22 is sleeved on the stabilizing column 222. The dressing cutter 23... 3. The grinding disc 14 is pressed against the ground surface 14, and then the mounting block 51 is placed on the stabilizing column 222. During this process, the top of the stabilizing column 222 applies pressure to the arc surface 611, causing the locking arc block 61 to move. The return spring 63 is compressed until the locking ring groove 2221 aligns with the moving groove. The locking arc block 61 moves in the opposite direction and enters the locking ring groove 2221 until the retaining ring 621 abuts against the inner side wall of the moving groove, thereby restricting the mounting block 51. Then, the adjusting screw 52 is rotated to drive the pressure table 54 to descend, thereby applying pressure to the extension plate 221 and realizing the installation of the tool holder 22.

[0053] During the finishing process, purple ink is applied to the grinding areas of the upper grinding disc 13 and the lower grinding disc 14. The hydraulic cylinder 16 is activated to lower the end cover 15 and the upper grinding disc 13 until it touches the top wall of the finishing blade 23. The inner motor 111 and the outer motor 121 are activated to make the inner turntable 11 and the outer turntable 12 rotate relative to each other. The upper grinding disc 13 is finished by the top of the finishing blade 23, and the lower grinding disc 14 is finished by the bottom of the finishing blade 23 until the colored ink in the grinding area is scraped off, thus achieving the effect of finishing the upper grinding disc 13 and the lower grinding disc 14.

[0054] By mounting the dressing blade 23 on the machine body 1, and cooperating with the upper grinding disc 13 and the lower grinding disc 14 rotating in opposite directions, the dressing blade 23 can dress the upper grinding disc 13 and the lower grinding disc 14 in one step, reducing the possibility of grooves on the surface of the upper grinding disc 13 and the lower grinding disc 14, ensuring the flatness of the grinding area of ​​the upper grinding disc 13 and the lower grinding disc 14, and improving the grinding effect of the grinding equipment.

[0055] In this embodiment, the trimming range of the upper grinding disc 13 and the lower grinding disc 14 is relatively small, in units of 0.5 μm, and the trimming range is usually between 0.5 and 5 μm.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
