Description

Technical Field

[0001] The invention relates to the technical field of micro bearing processing equipment, in particular to a diamond pen fine adjustment device. Background Art

[0002] With the continuous miniaturization, lightness and thin-walling of various industrial equipment and rotary devices, miniature bearings, as a member of the large family of bearings, are increasingly valued and favored, and the market demand for miniature bearings is also growing stronger. In fact, miniature bearings have a wide range of applications in various military and civilian industries, such as office equipment, micro motors, dental drills, video recorder drums, rotary encoders, computer peripherals, optical fiber transmission devices, optical exposure devices, precision testing instruments, micro robots, micro aircraft, etc.

[0003] The manufacturing of miniature rolling bearings mainly involves the processing of inner and outer rings, balls and cages. In terms of the formation mechanism of bearing ring quality, the grinding process is the most important, because the size, shape and position accuracy of the ring parts are mainly guaranteed by the grinding process. At present, the grinding of miniature bearing rings is carried out on a special bearing ring grinder, which uses a stepper motor or servo motor to drive the axial reciprocating motion of the grinding wheel to process the inner and outer rings of the bearing. The round-edged grinding wheel used for miniature bearing processing needs to be trimmed with a diamond pen before grinding. Before trimming the grinding wheel, the initial position of the diamond pen needs to be adjusted so that it is located at the center line position outside the grinding wheel. According to the different thickness of the grinding wheel, the position of the diamond pen needs to be manually adjusted by measurement before each trimming. The measurement and adjustment method has poor accuracy, troublesome operation, low efficiency, and is easy to cause the round edge of the grinding wheel to shift to one side. Summary of the invention

[0004] In order to overcome the above-mentioned technical problems, the purpose of the present invention is to provide a diamond pen fine-tuning device, which can clamp the grinding wheel through two clamping arms, and at the same time, the synchronous belt can be driven to roll through the synchronous wheel two, thereby driving the synchronous wheel one and the two-way screw to rotate synchronously, and the two-way screw can be driven to move away from each other, and the moving block will drive the linkage rod to rotate, so that when the moving block moves, it will drive the two positioning clamps to expand, so that when the clamping mechanism clamps the grinding wheel, the sliding column will move on the cross bar, and the sliding column will stop moving after the grinding wheel is completely clamped. At this time, the diamond pen is located at the midline position of the side of the grinding wheel, and the rotating shaft one can be driven to rotate in the opposite direction by rotating the handle in the opposite direction. Since the rotating shaft one is slidably sleeved with a square column, it is not easy to push the clamping mechanism to move when shaking the handle, thereby not affecting the position of the diamond pen, and the rotating shaft one rotating in the opposite direction will drive the two clamping arms and the grinding wheel to separate, and at the same time, the synchronous wheel one and the two-way screw will be driven to rotate in the opposite direction through the synchronous belt, thereby driving the two moving blocks to approach each other. Thereby, the positioning splints on both sides of the sliding column can be driven to gradually approach each other, and finally fit with the cross bar. The closer the positioning splints are to the cross bar, the greater the pressure on the rubber strip will be, thereby increasing the friction between the positioning splints and the cross bar. In this way, the sliding column can be fixed on the cross bar and the initial position of the diamond drill can be determined at the same time. In this way, the diamond pen can be quickly positioned at the center line position outside the grinding wheel according to the grinding wheels of different thicknesses, and the operation is simple and the positioning accuracy is high. When the round edge size of the grinding wheel needs to be adjusted, the rotating column can be moved so that the positioning ring is first connected with the fixed block, so that the position of the swing column can be limited, making it difficult to move laterally, and then the adjusting screw is driven to rotate by the handle, so that the sliding block can be driven to slide in the limiting plate, so that the distance between the swing column and the output shaft of the servo motor can be adjusted. When the distance is larger, the round edge of the grinding wheel is flatter, and when the distance is reduced, the round edge arc of the grinding wheel is larger. When dressing the grinding wheel, the rotating column needs to be kept upright, and the swing column is driven by the servo motor to swing back and forth slowly, so as to continuously adjust the direction of the diamond pen.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] Diamond pen fine adjustment device, including

[0007] The stand comprises two positioning plates, a cross bar is fixedly connected between the two positioning plates, and two rolling grooves are symmetrically provided on the outer wall of the cross bar;

[0008] The sliding positioning mechanism comprises a sliding column which is slidably sleeved with the cross bar, both ends of the sliding column are symmetrically fixedly connected with four fixing seats about its vertical center plane, a positioning clamping plate is rotatably connected between two adjacent fixing seats, a bidirectional screw is rotatably connected with the side wall of the sliding column, two moving blocks are symmetrically screwed and sleeved with respect to its vertical center plane, one end of two linkage rods are symmetrically rotatably connected with the side walls of the two moving blocks, the other end of the linkage rod is rotatably connected with a connecting rod fixedly connected with the positioning clamping plate, and a synchronous wheel 1 is fixedly sleeved with the end of the bidirectional screw;

[0009] A clamping mechanism, which is used to clamp the grinding wheel before dressing and then adjust the initial position of the device, and the clamping mechanism is fixed to the side wall of the sliding column along the length direction;

[0010] A linkage mechanism, the linkage mechanism is used to link the driving unit of the clamping mechanism and the driving unit of the sliding positioning mechanism, and the linkage mechanism is located between the clamping mechanism and the sliding positioning mechanism;

[0011] An adjustment mechanism is provided with a diamond pen fixedly thereon, and the adjustment mechanism is used to adjust the swing radius of the diamond pen, so as to adjust the round edge size of the micro-bearing grinding wheel for trimming, and the adjustment mechanism is located at the top of the sliding positioning mechanism.

[0012] Furthermore, the clamping mechanism includes an L-shaped plate fixedly connected to the side wall of the sliding column, the top end of the L-shaped plate is fixedly connected to a vertical plate, the side wall of the vertical plate is rotatably connected to a rotating shaft 1, two worms are fixedly sleeved on the outer wall of the rotating shaft 1, the top ends of the two worms are meshed with worm wheels, the center positions of the two worm wheels are fixedly sleeved with a rotating shaft 2 rotatably connected to the vertical plate, one end of the two rotating shafts 2 are fixedly sleeved with a rotating rod, one end of the two rotating rods are rotatably connected to a clamping arm, the two clamping arms are rotatably connected to a connecting rod rotatably connected to the vertical plate, the end of the rotating shaft 1 is fixedly sleeved with a synchronous wheel 2, and buffer pads are fixedly connected to the opposite side walls of the two clamping arms, and by arranging buffer pads on the opposite side walls of the two clamping arms, the extrusion force of the clamping arm on the grinding wheel can be buffered to prevent damage to the grinding wheel.

[0013] Furthermore, the linkage mechanism includes a synchronous belt, one end of which is socketed with a synchronous wheel 1, and the other end of which is socketed with a synchronous wheel 2. Through the transmission of the synchronous belt, when the synchronous wheel 1 rotates, it can drive the synchronous wheel 2 to rotate.

[0014] Furthermore, the adjusting mechanism includes a mounting plate fixedly connected to the top of the sliding column, a limiting plate fixedly connected to the side wall of the mounting plate, a sliding block slidably connected to the top of the limiting plate, a servo motor fixedly connected to the top of the sliding block, a swing plate fixedly connected to the output end of the servo motor, a limiting groove is provided on the swing plate, a limiting block is slidably embedded in the limiting groove, a swing column is fixedly connected to the top of the limiting block, the top of the swing column is fixedly connected to the diamond pen, an adjusting screw is screwed into the swing column, the end of the adjusting screw is rotatably connected to the swing plate, and the other end of the adjusting screw is fixedly connected to a handle, the adjusting mechanism can be used to adjust the trimming size of the round edge of the grinding wheel according to different grinding wheels, and the distance between the swing column and the output shaft of the servo motor can be adjusted. When the distance is larger, the round edge of the grinding wheel is flatter, and when the distance is reduced, the arc of the round edge of the grinding wheel is larger.

[0015] Furthermore, both sides of the interior of the sliding column are filled with multiple balls that slide with the rolling grooves. By filling the interior of the sliding column with balls that slide with the rolling grooves, when the clamping arm clamps the grinding wheel, the sliding column can slide on the cross bar to fine-tune the position of the diamond pen without causing excessive lateral force on the grinding wheel.

[0016] Furthermore, four rubber strips are fixedly connected to the arc-shaped inner wall of the positioning clamp at equal distances. When the positioning clamps are brought close to each other, an extrusion force is applied to the rubber strips, thereby increasing the friction between the positioning clamp and the cross bar, thereby indirectly fixing the position of the sliding column.

[0017] Furthermore, a square column is slidably inserted into one end of the rotating shaft, and a rotating handle is fixedly connected to the end of the square column. By slidingly inserting the square column into the rotating shaft, the clamping mechanism will not be easily pushed to move when the rotating handle is shaken, thereby not affecting the initial position of the diamond pen.

By keeping the rotating column flat, the positioning ring and the fixed block can be socketed, thereby limiting the position of the swing column.

[0019] Beneficial effects of the present invention:

[0020] 1. The grinding wheel can be clamped by two clamping arms, and the synchronous belt can be driven to roll by the synchronous wheel 2, so as to drive the synchronous wheel 1 and the bidirectional screw to rotate synchronously. The two moving blocks can be driven to move away from each other by the bidirectional screw, and the moving block will drive the linkage rod to rotate, so that the moving block will drive the two positioning clamps to expand when it moves. In this way, when the clamping mechanism clamps the grinding wheel, the sliding column will move on the cross bar. After the grinding wheel is completely clamped, the sliding column stops moving. At this time, the diamond pen is located at the midline position of the side of the grinding wheel. By rotating the handle in the opposite direction, the rotating shaft 1 can be driven to rotate in the opposite direction. Since the rotating shaft 1 is slidably sleeved with a square column, it is not easy to push the clamp when the handle is shaken. The clamping mechanism moves, so as not to affect the position of the diamond pen. The counter-rotating shaft 1 will drive the two clamping arms and the grinding wheel to separate, and at the same time, the synchronous belt will drive the synchronous wheel 1 and the bidirectional screw to rotate in the opposite direction, so as to drive the two moving blocks to approach each other, so as to drive the positioning splints on both sides of the sliding column to gradually approach each other, and finally fit with the cross bar. The closer the positioning splint is to the cross bar, the greater the pressure on the rubber strip will be, so as to increase the friction between the positioning splint and the cross bar, so as to fix the sliding column on the cross bar and determine the initial position of the diamond drill at the same time, so as to quickly position the diamond pen at the center line position outside the grinding wheel according to the grinding wheels of different thicknesses, and the operation is simple and the positioning accuracy is high.

[0021] 2. When it is necessary to adjust the circular edge size of the grinding wheel, the rotating column can be moved so that the positioning ring is first connected with the fixed block, thereby limiting the position of the swing column and making it difficult to move laterally. Then the adjusting screw is driven to rotate by the handle, thereby driving the sliding block to slide in the limit plate, so as to adjust the distance between the swing column and the output shaft of the servo motor. When the distance is larger, the flatter the circular edge of the grinding wheel, and when the distance is smaller, the arc of the circular edge of the grinding wheel is larger. When dressing the grinding wheel, the rotating column needs to be kept upright, and the servo motor is used to drive the swing column to swing slowly back and forth to continuously adjust the direction of the diamond pen.

[0043] Working principle: When in use, after the grinding wheel is installed, the rotating handle 313 in the clamping mechanism 300 can drive the square column 312 to rotate together with the rotating shaft 1 303, and the two worm gears 304 on the outer wall of the rotating shaft 1 303 can respectively drive the two worm wheels 305 on the top to rotate, so that the two rotating shafts 2 306 can be driven to rotate in opposite directions through the worm wheels 305, so that the rotating shaft 2 306 can drive the two rotating rods 307 to rotate, and the rotating rods 307 on the left and right sides can respectively drive the two clamping arms 308 to approach each other. Since the clamping arm 308 is also connected to the connecting rod 310, the clamping arm 308, the rotating rod 307 and the connecting rod 310 move in a parallelogram, so that the two clamping arms can be kept The opposite side walls of 308 are always kept parallel, and finally the grinding wheel can be clamped by the two clamping arms 308, and at the same time, the synchronous belt 401 can be driven to roll through the synchronous wheel 211, so as to drive the synchronous wheel 1 210 and the bidirectional screw 206 to rotate synchronously, and the two moving blocks 207 can be driven to move away from each other through the bidirectional screw 206, and the moving block 207 will drive the linkage rod 208 to rotate, so that when the moving block 207 moves, it will drive the two positioning clamps 204 to expand, so that when the clamping mechanism 300 clamps the grinding wheel, the sliding column 201 will move on the cross bar 102, and the sliding column 201 will stop moving after the grinding wheel is completely clamped, and the diamond pen 600 is located at the midline position of the side of the grinding wheel;

[0044] The shaft 1 303 can be driven to rotate in the opposite direction by rotating the handle 313 in the opposite direction. Since the shaft 1 303 is slidably sleeved with a square column 312, it is not easy to push the clamping mechanism 300 to move when the handle 313 is shaken, so that the position of the diamond pen 600 is not affected. The shaft 1 303 rotating in the opposite direction drives the two clamping arms 308 to separate from the grinding wheel, and at the same time drives the synchronous wheel 1 210 and the bidirectional screw rod 206 to rotate in the opposite direction through the synchronous belt 401, thereby driving the two moving blocks 207 to approach each other, so as to drive The positioning clamps 204 on both sides of the sliding column 201 gradually move closer and finally fit with the cross bar 102. The closer the positioning clamps 204 are to the cross bar 102, the greater the pressure on the rubber strip 205 will be, thereby increasing the friction between the positioning clamps 204 and the cross bar 102. In this way, the sliding column 201 can be fixed on the cross bar 102 and the initial position of the diamond drill 600 can be determined at the same time. In this way, the diamond pen 600 can be quickly positioned at the center line position outside the grinding wheel according to the grinding wheel of different thicknesses, and the operation is simple and the positioning accuracy is high.

[0045] When it is necessary to adjust the size of the circular edge of the grinding wheel, the rotating column 513 can be moved so that the positioning ring 514 is first connected to the fixed block 512, thereby limiting the position of the swing column 508 and making it difficult to move laterally. Then, the handle 510 is used to drive the adjusting screw 509 to rotate, thereby driving the sliding block 503 to slide in the limiting plate 502, so as to adjust the distance between the swing column 508 and the output shaft of the servo motor 504. When the distance is larger, the flatter the circular edge of the grinding wheel is, and when the distance is reduced, the arc of the circular edge of the grinding wheel is larger. When trimming the grinding wheel, the rotating column 513 needs to be kept upright, and the servo motor 504 is used to drive the swing column 508 to swing slowly back and forth, so as to continuously adjust the direction of the diamond pen 600.
