Description

Technical Field

[0001] This utility model relates to the technical field of grinding wheel dressers, specifically to a grinding wheel dresser for linear motor bearings. Background Technology

[0002] Traditional grinding wheel dressing involves moving the grinding wheel closer to a grinding wheel dresser. Each time, the dresser is manually fixed, and then the rotating grinding wheel is brought close to it. The dresser uses a diamond dressing tool to adjust the wheel. Because the grinding wheel dresser lacks fine-tuning capabilities, and the dresser must be removed after each dressing cycle, requiring the grinding wheel to be moved back to the surface to be ground for re-setting, the process is cumbersome and inefficient. Furthermore, the diamond dressing tool cannot be quickly installed and removed, making it difficult to replace when worn, significantly impacting the efficiency and accuracy of the grinding wheel dresser. Therefore, it is necessary to design a linear motor bearing grinding wheel dresser. Utility Model Content

[0016] Please see Figures 1-4 As shown, this utility model provides a technical solution: a linear motor bearing grinding wheel dresser, including an X-axis moving mechanism 1, a Y-axis moving mechanism 2, a rotating mechanism 3, and a diamond pen clamping mechanism 4. The X-axis moving mechanism 1 is mounted on the Y-axis moving mechanism 2, the rotating mechanism 3 is mounted on the X-axis moving mechanism 1, and the diamond pen clamping mechanism 4 is mounted on the rotating mechanism 3.

[0017] In this embodiment, the Y-axis moving mechanism 2 has the same structure as the X-axis moving mechanism 1. The X-axis moving mechanism 1 includes a slide table 101, a slider 102 mounted on the bottom of the slide table 101, the slider 102 slidably mounted on a slide rail 103, the slide rail 103 mounted on a base plate 104, and protective plates 105 mounted on both sides of the base plate 104. The slide table 101 is connected to a mover 106 via a connecting plate. A magnetic stator 107 is disposed below the mover 106. There is no contact between the magnetic stator 107 and the mover 106. The magnetic stator 107 is electrically driven. The magnetic force is converted into magnetic force, and the mover 106 drives the slide table 101 to perform reciprocating linear motion under the action of the magnetic force. A reading head mounting seat is also installed at the bottom of the slide table 101, and a reading head 108 is installed on the reading head mounting seat. A grating ruler 109 is set on one side of the reading head 108. The reading head 108 moves with the slide table 101 on the grating ruler 109 and reads data. It can convert displacement into digital pulse signals, thereby realizing high-precision displacement measurement and feedback. The grating ruler 109 is installed on the grating ruler fixing block, and the grating ruler fixing block is installed on the base plate 104.

[0018] The rotating mechanism 3 in this embodiment includes a rotating disk 301 and a motor that drives the rotating disk 301 to rotate. A rotating shaft 302 is installed at the bottom of the rotating disk 301. The rotating shaft 302 is connected to the output end of the motor. The motor is installed in a motor housing 303. The motor housing 303 is installed on a slide table 101. Multiple mounting brackets 304 are installed on the top of the motor housing 303. Rollers 305 are installed on the mounting brackets 304. The top of the rollers 305 abuts against the bottom of the rotating disk 301. The rollers 305 provide auxiliary support and rotation for the rotating disk 301, thereby ensuring smooth rotation of the rotating disk 301 and improving its reliability.

[0019] In this embodiment, a ratchet 306 is mounted on the rotating shaft 302. Multiple ratchet slots 307 are evenly arranged on the outer periphery of the ratchet 306. A thrust pawl 308 is provided on one side of the ratchet 306. One end of the thrust pawl 308 is hinged to the cylinder connector 309. The cylinder connector 309 is connected to the piston rod of the cylinder 310. The middle part of the thrust pawl 308 is rotatably mounted on the rotating shaft 311. The rotating shaft 311 is mounted on the motor housing 303 through the rotating shaft seat. A cylinder connecting block 312 is mounted on the cylinder body of the cylinder 310. The cylinder connecting block 312 is hinged to the cylinder mounting seat 313 through a cylindrical pin. The cylinder mounting seat 313 is fixed on the motor housing 303. When the diamond pen 5 needs to rotate at an angle, the cylinder 310 retracts, and the thrust pawl 308 swings through the cylinder connector 309, thereby causing the thrust pawl 308 to leave the ratchet slot 307 of the ratchet 306. The motor drives the rotating shaft 302 and the rotating disk 301 to rotate, thereby causing the diamond pen 5 to rotate at an angle. The cylinder 310 extends, causing the thrust pawl 308 to enter the ratchet slot 307 of the ratchet 306, thus achieving rotational locking.

[0020] The diamond pen clamping mechanism 4 in this embodiment includes a diamond pen mounting block 401, which is mounted on a support base 402. The support base 402 is mounted on a rotating disk 301. Fixing blocks 403 are mounted on both sides of the diamond pen mounting block 401. Movable insert rods 404 are slidably connected to the center of each of the two fixing blocks 403. Pull rings 405 are mounted on the movable insert rods 404. Spring grooves 406 are opened inside each of the two fixing blocks 403. Return springs 407 are sleeved on the outer walls of each of the two movable insert rods 404. Limiting blocks 408 are installed on each of the two movable insert rods 404. One end of the return spring 407 is connected to the limiting block 408, and the other end of the return spring 407 is connected to the side wall of the spring groove 406. Through holes 409 corresponding to the movable insert rods 404 are opened inside each of the two fixing blocks 403. The through holes 409 are connected to the spring grooves 406.

[0021] In this embodiment, the diamond pen mounting block 401 has a mounting slot 410 corresponding to the diamond pen 5. The diamond pen 5 can be inserted into the mounting slot 410. The diamond pen 5 has a locking groove 413 on its side wall. The locking groove 413 has a circular structure. Both sides of the mounting slot 410 have movable locking grooves 411 that communicate with the slot 410. The two movable locking grooves 411 are slidably disposed in the two locking blocks 412. The two locking blocks 412 have a semi-circular structure. By inserting the two locking blocks 412 into the locking grooves 413, the position of the diamond pen 5 is fixed and the diamond pen 5 is prevented from sliding out of the mounting slot 410. The locking pull rods 414 are fixedly connected to the side of the two locking blocks 412 away from the diamond pen 5. The pull rods 415 are fixedly connected to the end of the two locking pull rods 414 away from the locking blocks 412. 15. Pull the locking lever 414 to slide the two locking blocks 412 out of the locking groove 413, thereby releasing the fixation of the diamond pen 5. The two locking levers 414 have a fixing insertion hole 416 on the side near the pulling block 415 and a disassembly insertion hole 417 on the side near the locking block 412. The diameters of the two disassembly insertion holes 417 and the fixing insertion hole 416 correspond to the diameter of the movable insertion rod 404. When both movable insertion rods 404 are inserted into the corresponding disassembly insertion hole 417, the diamond pen 5 can be removed from the mounting slot 410. When both movable insertion rods 404 are inserted into the fixing insertion hole 416, the position of the diamond pen 5 can be locked. The diamond pen 5 has a foolproof limiting groove 501, and the side wall of the mounting slot 410 is provided with a limiting protrusion corresponding to the foolproof limiting groove 501.

[0022] The working principle of this utility model is as follows: When installing the diamond pen 5, pull the pull ring 405 to slide the movable insert rod 404 into the through hole 409 of the fixing block 403. Then pull the pull block 415 to align the disassembly insertion hole 417 of the locking pull rod 414 with the position of the movable insert rod 404. Then release the pull ring 405, and the movable insert rod 404 is inserted into the disassembly insertion hole 417. At this time, the diamond pen 5 can be inserted into the mounting slot 410, so that the limiting protrusion is inserted into the anti-foolproof limiting groove 501. Then pull the pull ring 405 again to move the movable insert rod 404 into the through hole 409 of the fixing block 403. 4. Slide out from the disassembly hole 417, then push the pull block 415 so that both locking blocks 412 are inserted into the locking groove 413. At this time, the position of the fixed insertion hole 416 corresponds to the position of the movable insertion rod 404. Then release the pull ring 405 so that the bottom of the movable insertion rod 404 passes through the fixed insertion hole 416 and is inserted into the through hole, thereby realizing the installation of the diamond pen. By opening the fixed insertion hole 416 and the disassembly hole 417 on the locking pull rod 414, and using it in conjunction with the movable insertion rod 404, it is convenient to disassemble and install the diamond pen, making the replacement of the diamond pen simpler and faster.
