Description

Technical Field

[0001] The present invention relates to the technical field of bearing processing, and particularly relates to a PCD bearing hole forming reamer and its equipment. Background Art

[0002] A reamer is a rotary cutting tool with one or more cutting teeth used to remove a thin layer of metal from the surface of a machined hole. The reamer is a rotary finishing tool with a straight edge or a spiral edge, used for enlarging or finishing a hole. Due to the small amount of cutting, the machining accuracy requirements of the reamer are usually higher than those of a drill bit. It can be operated manually or installed on a drilling machine for work.

[0003] When manufacturing and processing bearings, after drilling the middle part of the bearing with a drilling device, a large number of burrs, irregular protrusions or depressions will appear on the inner wall of the bearing hole. Therefore, a reamer is needed to finish the inner wall of the bearing hole to remove the burrs on the inner wall of the bearing hole and make the bearing hole smoother and flatter. When the current machine tool finishes the bearing hole, the staff needs to manually fix each bearing on the machine tool one by one, and then the machine tool controls the reamer to rotate and move to finish the bearing hole. The processed bearings also need to be manually removed from the machine tool by the staff. During the bearing processing, the staff needs to perform frequent repetitive work, which not only increases the workload of the staff, but also reduces the efficiency of bearing processing. In addition, when the staff places and takes the bearings, they will be in close contact with the machine tool and the reamer on the machine tool, making it easy for the staff to be injured by the components on the machine tool such as the reamer, endangering the personal safety of the staff.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. In the present invention, through the setting of the PCD cutting edge, the overall rigidity of the reamer is improved, and at the same time, the service life of the reamer is increased, saving the time occupied by frequent tool changing and tool alignment; in addition, the PCD cutting edge can adapt to the working state of high-speed rotation, and no cutting fluid is required during the grinding work, so that the processing time of the reamer for the bearing is shorter, thereby increasing the efficiency of the bearing processing work.

[0018] 2. In the present invention, through the arrangement of the transmission component, the second motor rotates the lead screw, enabling the lead screw to synchronously drive the slide seat to move towards the transfer component. The two slide rails can not only ensure the stability of the slide seat during movement but also reduce the friction when the slide seat moves, making the slide seat move more smoothly, thereby reducing the bearing pressure on the second motor and the lead screw and extending the service life of the second motor and the lead screw. When the slide seat moves, it can synchronously drive the pushing component to move, causing the toothed plate and the pushing plate of the pushing component to move towards the transfer component. Moreover, when the pushing plate moves, it can push the bearing to move until the bearing is pushed into the storage bin by the pushing plate. The acting force generated by the torsion spring on the rotating plate of the pushing plate can offset the pressure generated by the bearing on the rotating plate, enabling the rotating plate to always maintain stability when driving the bearing to move. During the movement of the slide seat, the first motor drives the driven gear to rotate through the driving gear, and the driven gear controls the chuck and the tool body to rotate rapidly through the transmission shaft, enabling the tool body to enter the rapid rotation state in advance, ensuring that the tool body can process the bearing immediately when it contacts the bearing.

[0019] 3. In the present invention, through the arrangement of the transfer component, as the pushing plate continuously approaches the storage bin, the bearing is pushed into the storage bin by the pushing plate. Then, the lead screw continues to drive the slide seat to move, and the pushing plate continues to move under the movement of the slide seat until the acting force of the torsion spring on the rotating plate is less than the thrust received by the rotating plate. At this time, the rotating plate will rotate into the storage groove of the storage plate. Without the obstruction of the rotating plate, the storage plate and the toothed plate will continue to move under the drive of the slide seat. When the toothed plate moves to the second gear, the toothed plate will engage with the second gear and drive the second gear to rotate. The second gear synchronously drives the first gear to rotate through the worm and the worm gear. When the first gear rotates, it drives the storage bin to rotate to the height and position corresponding to the reamer, enabling the reamer to normally process the bearing in the storage bin. During the rotation of the first gear, the ejector cylinder can control the ejector block to move, enabling the ejector block to simply press on the bearing, ensuring that the bearing can remain stable in the storage bin and preventing the bearing from shaking or falling off the storage bin when the reamer processes the bearing. In addition, the worm and the worm gear are one-way transmission. The worm can drive the worm gear to rotate, and the worm gear cannot drive the worm to rotate. When the toothed plate passes through the second gear, the worm can clamp the worm gear, thereby locking the first gear and preventing the first gear from rotating randomly, keeping the position of the storage bin always stable.

[0020] 4. In the present invention, through the settings of the pushing plate and the toothed plate, during the stage when the pushing plate pushes the bearing, the rotating plate rotates into the inner side of the receiving plate under the extrusion force greater than the acting force of the torsion spring. After that, the receiving plate will move to the other side of the storage bin. At this time, the extrusion force on the rotating plate disappears, and the torsion spring can control the rotating plate to rotate and reset again. After the bearing is processed, the transmission component drives the reamer component to move backward and reset. The rotating plate and the toothed plate move backward synchronously. The toothed plate first uses the second gear to drive the first gear to rotate backward first, enabling the first gear to move the storage bin to the initial position. Then, the rotating plate enters the storage bin through the rectangular through groove on the rotating plate storage bin and pushes out the bearing in the storage bin. By using the pushing plate and the torsion spring, it is possible to both push the unprocessed bearing into the storage bin and push out the processed bearing from the storage bin, and the whole process does not require manual operation by the staff, which not only reduces the workload of the staff but also increases the work efficiency.

[0021] 5. In the present invention, through the setting of the chassis, before the transmission component drives the reamer component, the pushing cylinder first uses the pushing block to push the unprocessed bearing to the pushing component. At this time, the position of the bearing corresponds to the position of the roller. When the pushing component pushes the bearing, the bearing moves on the roller, and multiple rollers can reduce the friction at the bottom when the bearing moves, which can both reduce the resistance when the pushing component pushes the bearing and prevent the bearing from tipping over during movement. The processed bearing will be pushed by the pushing component into the chute. There is a slope in the chute, and the bearing slides out of the chassis along the slope of the chute under the action of gravity, facilitating collection by the staff.

[0049] The preferred implementation manners of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0050] As Figure 20 shown, an embodiment of the present invention discloses a PCD bearing hole forming reamer, including a cutter body 16, the cutter body 16 includes a cutter head 162, and a cutter handle 161 is welded in the middle of one end of the cutter head 162. The cutter handle 161 is circular and its length is greater than the length of the cutter head 162; a plurality of edge grooves 163 are evenly arranged at the end of the cutter head 162 away from the cutter handle 161, and PCD cutting edges 164 are fixedly installed inside each of the plurality of edge grooves 163; the PCD cutting edges 164 are made of PCD polycrystalline diamond; the edge - opening parts of the plurality of PCD cutting edges 164 are all located outside the cutter head 162.

[0051] Through the setting of the PCD cutting edges 164, the overall rigidity of the cutter body 16 is improved, and at the same time, the service life of the cutter body 16 is increased, saving the time occupied by frequent tool changing and tool alignment; in addition, the PCD cutting edges 164 can adapt to the working state of high - speed rotation, and no cutting fluid is required during the grinding work, so that the processing time of the cutter body 16 for the bearing is shorter, thereby increasing the efficiency of the bearing processing work.

[0052] As Figure 1 - 20As shown in the figure, an embodiment of the present invention discloses a device with a PCD bearing hole forming reamer, which includes a reamer assembly 1 for machining a bearing 9. The reamer assembly 1 is in transmission connection with a transmission assembly 2; a bracket 3 is provided below the reamer assembly 1, and the transmission assembly 2 is fixedly connected to the top of the bracket 3; a transfer assembly 4 is provided at one end of the bracket 3 away from the reamer assembly 1, and a machine case 7 is provided on one side of the transfer assembly 4 away from the bracket 3. A controller 8 is embedded at the upper end of the machine case 7; the bottoms of the machine case 7 and the bracket 3 are both welded to the top of a chassis 6;

[0053] The reamer assembly 1 includes a sliding seat 11. Both ends of the bottom of the sliding seat 11 are welded with first connecting seats 10, and threaded holes are provided in the middle of the two first connecting seats 10; one end of the top of the sliding seat 11 close to the transfer assembly 4 is fixedly connected by bolts to a second connecting seat 12. A transmission shaft 14 is rotatably connected to the inner side of the upper end of the second connecting seat 12; one end of the transmission shaft 14 close to the transfer assembly 4 is fixedly connected to a chuck 15, and the other end is fixedly connected to a driven gear 13;

[0054] The bottom of the driven gear 13 meshes with a driving gear 17. The middle of the driving gear 17 is fixedly connected to the output shaft of a motor 18. The motor 18 is fixedly connected to the top of the sliding seat 11 by bolts; one side of the bottom of the sliding seat 11 is welded with a feeding component 19; the middle of one side of the chuck 15 away from the transmission shaft 14 is fixedly connected to a cutter body 16.

[0055] Through the setting of the transmission assembly 2, the motor 21 can drive the sliding seat 11 to move in the direction of the transfer assembly 4 by rotating the lead screw 22. The two slide rails 25 can not only ensure the stability of the sliding seat 11 during movement, but also reduce the friction force of the sliding seat 11 during movement, making the sliding seat 11 move more smoothly, thereby reducing the bearing pressure on the motor 21 and the lead screw 22 and extending the service life of the motor 21 and the lead screw 22; when the sliding seat 11 moves, it can synchronously drive the feeding component 19 to move, making the toothed plate 194 and the feeding plate 195 of the feeding component 19 move in the direction of the transfer assembly 4, and the feeding plate 195 can push the bearing 9 to move when moving until the bearing 9 is pushed into the storage bin 42 by the feeding plate 195; the acting force of the torsion spring 1954 on the push plate 1952 can offset the pressure generated by the bearing 9 on the rotating plate 1952, so that the rotating plate 1952 can always maintain stability when driving the bearing 9 to move; during the movement of the sliding seat 11, the motor 18 drives the driven gear 13 to rotate through the driving gear 17, and the driven gear 13 controls the chuck 15 and the cutter body 16 to rotate rapidly through the transmission shaft 14, making the cutter body 16 enter the rapid rotation state in advance to ensure that the cutter body 16 can process the bearing 9 immediately when contacting the bearing 9.

[0056] As Figure 1 - 22As shown, the pusher component 19 includes two vertical rods 191. The tops of the two vertical rods 191 are welded to the bottom of the slide 11, and the bottoms are fixedly connected to the connecting rod 192. One end of the connecting rod 192 away from the vertical rod 191 is welded with a connecting frame 193. On the side of the connecting frame 193 away from the slide 11, a toothed plate 194 is welded, and the length of the toothed plate 194 is the same as that of the connecting frame 193. One end of the connecting frame 193 away from the connecting rod 192 is welded to the pusher plate 195.

[0057] The pusher plate 195 includes a storage plate 1951. One end of the storage plate 1951 is welded to the connecting frame 193, and the other end is provided with two rotating plates 1952. Two storage grooves are symmetrically arranged on the storage plate 1951. The inner sides of the two storage grooves away from the connecting frame 193 are fixedly connected with connecting shafts 1953, and one ends of the two rotating plates 1952 are respectively rotatably connected to the two connecting shafts 1953. Torsion springs 1954 are sleeved on the outer sides of the connecting shafts 1953. One end of the torsion spring 1954 is fixedly connected to the storage plate 1951, and the other end is fixedly connected to the rotating plate 1952. Rubber sleeves 1955 are sleeved on the outer sides of the two rotating plates 1952.

[0058] The transmission component 2 includes a screw rod 22. The two ends of the screw rod 22 are respectively rotatably connected to two bearing seats 23. The two bearing seats 23 are fixedly connected to the top of the bracket 3 by bolts. The two first connection seats 10 are respectively threadedly connected to the screw rod 22 through their threaded holes. One end of the screw rod 22 away from the transfer component 4 is fixedly connected to the output shaft of the second motor 21. The bottom of the second motor 21 is fixedly connected to the placement frame 24 by bolts. One side of the upper end of the placement frame 24 is fixedly connected to the bracket 3. On both sides of the screw rod 22, there are slide rails 25. The lengths of the two slide rails 25 are the same as that of the screw rod 22, and the two slide rails 25 are respectively slidably connected to the two sides of the bottom of the slide 11.

[0059] With the arrangement of the transfer component 4, as the pushing plate 195 continuously approaches the storage bin 42, the bearing 9 is pushed into the storage bin 42 by the pushing plate 195. Then, the screw rod 22 continues to drive the sliding seat 11 to move, and the pushing plate 195 continues to move under the movement of the sliding seat 11 until the acting force of the torsion spring 1954 on the rotating plate 1952 is less than the thrust received by the rotating plate 1952. At this time, the rotating plate 1952 will rotate into the storage groove of the storage plate 1951. Without the obstruction of the rotating plate 1952, the storage plate 1951 and the toothed plate 194 will continue to move under the drive of the sliding seat 11. When the toothed plate 194 moves to the second gear 47, the toothed plate 194 will engage with the second gear 47 and drive the second gear 47 to rotate. The second gear 47 will synchronously drive the first gear 41 to rotate through the worm 44 and the worm gear 43. When the first gear 41 rotates, it drives the storage bin 42 to rotate, so that the storage bin 42 rotates to the height and position corresponding to the tool body 16, enabling the tool body 16 to normally process the bearing 9 in the storage bin 42. During the rotation of the first gear 41, the ejector cylinder 45 can control the movement of the ejector block 46, so that the ejector block 46 only presses on the bearing 9, enabling the bearing 9 to remain stable in the storage bin 42 and preventing the bearing 9 from shaking or falling off the storage bin 42 when the tool body 16 processes the bearing 9; in addition, the worm 44 and the worm gear 43 are one-way transmissions. The worm 44 can drive the worm gear 43 to rotate, and the worm gear 43 cannot drive the worm 44 to rotate. When the toothed plate 194 passes through the second gear 47, the worm 44 can clamp the worm gear 43, thereby locking the first gear 41 and preventing the first gear 41 from rotating randomly, so that the position of the storage bin 42 always remains stable.

[0060] As Figure 1 - 22 shown, the transfer component 4 includes a first gear 41, and a storage bin 42 for placing the bearing 9 is welded to the bottom of the first gear 41; a top feed cylinder 45 is fixedly connected to the middle of the top of the storage bin 42, and the telescopic rod of the top feed cylinder 45 is fixedly connected to the ejector block 46. The ejector block 46 is located inside the upper end of the storage bin 42. A through groove for the ejector block 46 to pass through is provided in the middle of the top of the storage bin 42; one side of the first gear 41 close to the pushing component 19 is engaged with the worm gear 43, and the side of the worm gear 43 away from the first gear 41 is connected with the worm 44 in a matching manner; the lower end of the worm 44 is fixedly connected to the middle of the second gear 47; the second gear 47 is located on the side of the toothed plate 194 away from the connecting frame 193, and the second gear 47 and the toothed plate 194 are on the same horizontal line; two rectangular through grooves penetrating the storage bin 42 are symmetrically provided on one side of the storage bin 42 close to the second gear 47, and the positions of the two rectangular through grooves correspond to the two rotating plates 1952 respectively.

[0061] Through the settings of the pushing plate 195 and the toothed plate 194, during the stage when the pushing plate 195 pushes the bearing 9, the rotating plate 1952 rotates into the inner side of the receiving plate 1951 under the extrusion force greater than the acting force of the torsion spring 1954. After that, the receiving plate 1951 will move to the other side of the storage bin 42. At this time, the extrusion force on the rotating plate 1952 disappears, and the torsion spring 1954 can control the rotating plate 1952 to rotate and reset again; after the bearing 9 is processed, the transmission component 2 drives the reamer component 1 to move backward and reset. The rotating plate 1952 and the toothed plate 194 move synchronously in the reverse direction. The toothed plate 194 first drives the first gear 41 to rotate in the reverse direction through the second gear 47, so that the first gear 41 moves the storage bin 42 to the initial position. Then, the rotating plate 1952 enters the storage bin 42 through the rectangular through groove on the storage bin 42 of the rotating plate 1952 and pushes out the bearing 9 in the storage bin 42; by using the pushing plate 195 and the torsion spring 1954, the unprocessed bearing 9 can be pushed into the storage bin 42, and the processed bearing 9 can be pushed out of the storage bin 42. And the whole process does not require manual operation by the staff, which not only reduces the workload of the staff but also increases the work efficiency.

[0062] As Figure 1 - 8 Shown in Figures 14 - 22, the chassis 6 includes a chassis main body 61. A support frame 66 is welded to one side of the chassis main body 61 close to the transfer component 4, and both the first gear 41 and the worm gear 43 are rotatably connected to the support frame 66; the bottom of the worm 44 is rotatably connected to the support frame 66 and the bottom is rotatably connected to the chassis main body 61; an arc-shaped groove for the normal rotation of the storage bin 42 is provided at the position of the chassis main body 61 corresponding to the storage bin 42; a rectangular groove is provided at the top of the chassis main body 61. The position of the rectangular groove corresponds to the position of the rotating plate 1952, and the length of the rectangular groove is the same as the distance between the rotating plate 1952 and the storage bin 42; a plurality of rollers 62 are evenly and rotatably connected in the rectangular groove, and the tops of the rollers 62 are flush with the top of the chassis main body 61;

[0063] Limit plates 63 are provided on both sides of the rectangular groove of the chassis main body 61. The bottoms of the two limit plates 63 are welded to the chassis main body 61, and the distance between the two limit plates 63 is the same as the length of the bearing 9; a chute 64 is provided at one end of the rectangular groove of the chassis main body 61 away from the transfer component 4, and the chute 64 is located on the chassis main body 61; a side plate 65 is provided on one side of the rectangular groove away from the toothed plate 194. The bottom of the side plate 65 is welded to the chassis main body 61, and the space between the side plate 65 and the side of the chassis main body 61 is for temporarily storing the bearing ⑨; a pushing cylinder 5 is fixedly connected to one side of the chassis main body 61 close to the side plate 65. The position of the pushing cylinder 5 corresponds to the position of the rotating plate 1952, and a pushing block for pushing the bearing 9 is fixedly connected to the telescopic rod of the pushing cylinder 5.

[0064] Through the setting of the chassis 6, before the transmission component 2 drives the reamer component 1, the pusher cylinder 5 first uses the push block to push the unprocessed bearing 9 to the pusher component 19. At this time, the position of the bearing 9 corresponds to the position of the roller 62; when the pusher component 19 pushes the bearing 9, the bearing 9 moves on the roller 62. The multiple rollers 62 can reduce the frictional force at the bottom when the bearing 9 moves, which can not only reduce the resistance when the pusher component 19 pushes the bearing 9, but also prevent the bearing 9 from tipping over when moving; the processed bearing 9 will be pushed by the pusher component 19 into the chute 64. There is a slope in the chute 64, and the bearing 9 slides out of the chassis 6 along the slope of the chute 64 under the action of gravity, which is convenient for the staff to collect.
