Description

Technical Field

[0001] The present invention belongs to the technical field of manufacturing other metal processing machinery, and specifically relates to a gear processing inner ring grinding device. Background Art

[0002] The machining of the inner hole of a gear is an important link in gear manufacturing. When machining the inner hole of a gear, the machining of the inner hole of the gear is divided into rough machining and finish machining. First, the inner hole on the gear is roughly machined by a turning device, and then the inner hole is further ground by a grinding device to make the accuracy of the inner hole meet the assembly requirements.

[0003] The patent with the publication number CN219787690U discloses a gear inner hole grinding device, including a device body. The device body includes an operating table, a slider, a grinding head, and a positioning component. The slider is movably installed on the operating table, and a motor for driving the grinding head is fixedly installed on the slider. The positioning component includes a mounting table, a positioning box, a cylinder, a plurality of brackets, and a positioning ring. This solution is provided with a material receiving component. With this design, the debris generated by grinding passes through the leakage slot and falls into the inside of the material receiving box for collection. When a certain amount of debris is collected, by holding the material receiving box and lifting it upward, the positioning block is no longer stuck in the positioning slot, and then the material receiving box is pulled out from the fixing frame, so that the metal debris can be centrally processed.

[0004] In the above solution, before grinding the inner hole of the gear, the gears need to be placed into the positioning box one by one, and then the gears can be ground. Conversely, when the gears are ground, the gears in the positioning box need to be removed, and after placing the gears to be ground, the next set of grinding can be carried out. During this process, the taking and placing of the gears waste a lot of time and reduce the efficiency of gear grinding. Therefore, the present invention provides a gear processing inner ring grinding device. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: A gear processing inner ring grinding device of the present invention includes a machine table. A turntable mechanism is arranged on the machine table. A linear sliding table mechanism is arranged on one side of the turntable mechanism. The linear sliding table mechanism is fixedly installed on the machine table. A movable seat is installed on the linear sliding table mechanism. A grinding rod is rotatably installed on the movable seat. The turntable mechanism includes a driving column. The driving column is rotatably installed on the machine table. A disk body fixedly installed on the driving column. Feeding grooves for placing workpieces are equally angularly opened on the disk body. A bracket for supporting the workpiece is arranged at the bottom of the feeding groove. Two groups of limiting blocks for engaging the workpiece are symmetrically arranged in the feeding groove. The rotating disk body enables the workpieces to pass through the feeding point and under the grinding rod in sequence. During the grinding process of the workpieces, the staff can simultaneously remove the ground workpieces and place the workpieces to be ground into the feeding groove, thus saving the time for workpiece picking and placing and improving the grinding efficiency of the workpieces.

[0007] Preferably, the bracket includes a support frame located at the bottom of the feeding groove, a receiving plate fixedly connected to the support frame, rollers rotatably mounted on the receiving plate, one end of a first spring closely attached to the support frame, three groups of guiding grooves equiangularly formed on the lower end surface of the disk body, the support frame slidably connected to the guiding grooves, the other end of the first spring closely attached to the inner wall of the guiding grooves, a guiding ring fixedly mounted on the machine table, the rollers rollingly connected to the inner ring of the guiding ring, the inner ring of the guiding ring composed of an annular surface, a first inclined surface and a second inclined surface, and the machine table is further provided with a conveyor belt mechanism for conveying workpieces, and a receiving table is arranged on one side of the conveyor belt mechanism; Under the combined action of the annular surface, the first inclined surface, the second inclined surface, the rollers, the first spring, the receiving table and the conveyor belt mechanism, automatic blanking of the workpieces is realized, which not only reduces the workload of the staff, but also improves the automation rate of the device.

[0008] Preferably, the machine table is further provided with a feeding mechanism. The feeding mechanism includes two groups of guiding frames both fixedly mounted on the machine table, a movable plate slidably connected to the two groups of guiding frames on both sides respectively, a storage bucket for storing workpieces arranged on the movable plate, the storage bucket clamped between two groups of bottom plates, one end of the bottom plate far from the storage bucket fixedly connected to the guiding frame, the lower end surface of the movable plate fitting the upper end surface of a gear, a rotating shaft installed in the middle of the gear, the rotating shaft rotatably mounted on a base, the base fixedly mounted on the machine table, a feeding groove formed on the movable plate, three groups of arc-shaped racks for driving the gear equiangularly arranged on the outer circle of the disk body, a guiding groove formed on the lower end surface of the movable plate, and a pin shaft arranged on the gear, and the pin shaft is located in the guiding groove; Since the feeding mechanism can automatically feed the workpieces and can store multiple groups of workpieces at one time, one staff member can supply workpieces to multiple groups of feeding mechanisms, which not only improves the work efficiency of the staff, but also further improves the automation rate of the device.

[0009] Preferably, a limiting mechanism is arranged between the gear and the base. The limiting mechanism includes three groups of tooth blocks equiangularly distributed on the lower end surface of the gear, a tooth disk meshing with the tooth blocks, a guide post slidably connected to the tooth disk, the lower end of the guide post fixedly connected to the base, the upper end of a second spring closely attached to the tooth disk, and the second spring and the tooth disk are both sleeved on the rotating shaft; When the gear rotates, the gear drives the rotating shaft and the three sets of tooth blocks to rotate together. At the same time, the three sets of tooth blocks squeeze the tooth grooves on the tooth disc, causing the tooth disc to slide down along the guide column, and the tooth disc compresses the second spring until the three sets of tooth blocks engage with the tooth disc again under the action of the rebound force of the second spring. When the gear is staggered from the arc-shaped rack, the meshing force between the tooth disc and the tooth block prevents the gear from rotating, thereby ensuring that the workpiece in the feed trough can fall accurately into the discharge trough.

[0010] The beneficial effects of the present invention are as follows: 1. The rotating disc can make the workpiece pass through the loading point and under the grinding rod in turn, so that during the grinding process, the staff can simultaneously remove the ground workpiece and put the workpiece to be ground into the discharge trough, saving the time of taking and placing the workpiece and improving the grinding efficiency of the workpiece.

[0011] 2. When the disc drives the workpiece to rotate 120 degrees under the grinding rod, the roller will roll along the annular surface. When the workpiece is ground, the disc drives the workpiece to continue rotating 120 degrees. The roller rolls along the annular surface to the first inclined surface, and the roller is squeezed by the first inclined surface, so that the roller drives the receiving plate and the support frame to move toward the axis of the disc, and the receiving plate slides along the guide groove. At the same time, the receiving plate compresses the first spring until the roller rolls to the intersection of the first inclined surface and the second inclined surface. In this process, the support frame releases its support for the workpiece, and the workpiece will first fall onto the receiving table. At the same time, the disc drives the workpiece to slide along the receiving table through the guide groove, so that the workpiece slides onto the conveyor belt mechanism, and the workpiece is transported to the next process through the conveyor belt mechanism, thereby realizing automatic unloading of the workpiece, which not only reduces the workload of the staff, but also improves the automation rate of the device.

[0012] 3. The three sets of arc-shaped racks rotate with the disc body. As the arc-shaped racks rotate, one set of arc-shaped racks will mesh with the gears and drive the gears to rotate. The rotating gears drive the pins to rotate, and the pins drive the movable plate to move through the guide grooves, so that the feed trough on the movable plate moves toward the bottom of the storage barrel until the feed trough moves to just below the storage barrel. Under the action of the guide grooves, it makes a brief pause so that the workpiece in the storage barrel falls into the feed trough, and the rotating gears support the workpiece. Then the workpiece returns to its initial position with the feed trough. At this time, the gears are just staggered with the arc-shaped racks, and the workpiece in the feed trough automatically falls into the discharge trough on the disc body, realizing automatic loading of the workpiece. Since the loading mechanism can automatically load the workpiece and can store multiple sets of workpieces at a time, one staff member can provide workpieces to multiple sets of loading mechanisms, which not only improves the work efficiency of the staff, but also further improves the automation rate of the device.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0026] Embodiment 1: As Figure 1 shown in Figure 2 FIG. 7, a gear processing inner ring grinding device according to an embodiment of the present invention includes a machine table 1, a turntable mechanism 2 is arranged on the machine table 1, a linear slide table mechanism 3 is arranged on one side of the turntable mechanism 2, the linear slide table mechanism 3 is fixedly installed on the machine table 1, a movable seat 4 is installed on the linear slide table mechanism 3, a grinding rod 5 is rotatably installed on the movable seat 4, the turntable mechanism 2 includes a driving column 201, the driving column 201 is rotatably installed on the machine table 1, a disk body 202 fixedly installed on the driving column 201, a material placing groove 203 for placing a workpiece 7 is equally angularly opened on the disk body 202, a bracket 204 for supporting the workpiece 7 is arranged at the bottom of the material placing groove 203, and two groups of limiting blocks 2031 for engaging the workpiece 7 are symmetrically arranged in the material placing groove 203.

[0027] Specifically, the position indicated by the arrow in Figure 1 FIG. 7 is the loading point. In the initial state, a group of material placing grooves 203 are located at the loading point. When the inner ring of the gear needs to be ground, the workpiece 7 is placed in the material placing groove 203 located at the loading point, and both groups of limiting blocks 2031 in the material placing groove 203 engage the teeth on the workpiece 7. Then, the driving column 201 is rotated by a motor, and the driving column 201 drives the disk body 202 together with the workpiece 7 to rotate 120 degrees. The direction indicated by the arrow in Figure 2 FIG. 7 is the rotation direction, so that the workpiece 7 rotates to directly below the grinding rod 5. Then, another motor is used to drive the grinding rod 5 to rotate, and at the same time, the linear slide table mechanism 3 drives the movable seat 4 together with the rotating grinding rod 5 to move towards the inner ring of the workpiece 7, so that the grinding rod 5 grinds the inner ring of the workpiece 7. During this process, the next group of workpieces 7 can be continuously placed into the next group of material placing grooves 203 until the inner ring of the workpiece 7 is completely ground by the grinding rod 5. Then, the grinding rod 5 is withdrawn, and the disk body 202 is continuously driven to rotate, so that the next group of workpieces 7 rotate to directly below the grinding rod 5. During the process of the grinding rod 5 grinding the next group of workpieces 7, the ground workpieces 7 can be taken out from the corresponding material placing grooves 203, and at the same time, the workpieces 7 to be ground are placed into the material placing grooves 203. The above operations are repeated in a cycle. Compared with the prior art, the rotating disk body 202 can enable the workpiece 7 to pass through the loading point and directly below the grinding rod 5 in sequence. During the grinding process of the workpiece 7, the staff can simultaneously remove the ground workpiece 7 and place the workpiece 7 to be ground into the material placing groove 203, saving the time for taking and placing the workpiece 7 and improving the grinding efficiency of the workpiece 7.

[0028] As Figures 3 to 5As shown in the figure, the bracket 204 includes a support frame 2041 located at the bottom of the material placing groove 203, a receiving plate 2042 fixedly connected to the support frame 2041, a roller 2043 rotatably mounted on the receiving plate 2042, one end of a first spring 2044 closely attached to the support frame 2041, three groups of guide grooves 2032 equiangularly formed on the lower end surface of the disc body 202, the support frame 2041 is slidably connected to the guide grooves 2032, and the other end of the first spring 2044 is closely attached to the inner wall of the guide grooves 2032. A guiding ring 101 is fixedly installed on the machine table 1, the roller 2043 is in rolling connection with the inner ring of the guiding ring 101, and the inner ring of the guiding ring 101 is composed of an annular surface 1011, a first inclined surface 1012, and a second inclined surface 1013. The machine table 1 is further provided with a conveyor belt mechanism 102 for conveying the workpiece 7, and a receiving table 103 is arranged on one side of the conveyor belt mechanism 102.

[0029] Specifically, the above requires manual picking and placing of the workpiece 7 by the staff, reducing the automation rate of the device. When the workpiece 7 is placed in the material placing groove 203, the support frame 2041 supports the workpiece 7. When the disc body 202 drives the workpiece 7 to rotate to below the grinding rod 5, the roller 2043 will roll along the annular surface 1011. After the workpiece 7 is polished, the disc body 202 drives the workpiece 7 to continue rotating by 120 degrees, and the roller 2043 rolls from the annular surface 1011 onto the first inclined surface 1012, and the roller 2043 is squeezed by the first inclined surface 1012, causing the roller 2043 to drive the receiving plate 2042 together with the support frame 2041 to move towards the axis direction of the disc body 202, and the receiving plate 2042 slides along the guide groove 2032. At the same time, the receiving plate 2042 compresses the first spring 2044 until the roller 2043 rolls to the intersection of the first inclined surface 1012 and the second inclined surface 1013. During this process, the support frame 2041 releases the support on the workpiece 7, and the workpiece 7 will first fall onto the receiving table 103. At the same time, the disc body 202 drives the workpiece 7 to slide along the receiving table 103 through the guide groove 2032, so that the workpiece 7 slides onto the conveyor belt mechanism 102, and the conveyor belt mechanism 102 conveys the workpiece 7 to the next process. When the disc body 202 continues to rotate, under the action of the rebounding force of the first spring 2044, the roller 2043 rolls along the second inclined surface 1013 until the roller 2043 rolls back onto the annular surface 1011 again, and the support frame 2041 supports the workpiece 7 again. With the combined action of the annular surface 1011, the first inclined surface 1012, the second inclined surface 1013, the roller 2043, the first spring 2044, the receiving table 103, and the conveyor belt mechanism 102, automatic blanking of the workpiece 7 is realized, which not only reduces the workload of the staff, but also improves the automation rate of the device.

[0030] Embodiment 2: As Figures 6 to 10As shown, in contrast to Example 1, another embodiment of the present invention is as follows: a loading mechanism 6 is further provided on the machine 1, and the loading mechanism 6 includes two sets of guide frames 601, both sets of guide frames 601 are fixedly mounted on the machine 1, and the two sides of the movable plate 602 are slidably connected to the two sets of guide frames 601, and a storage barrel 603 for storing the workpiece 7 is provided on the movable plate 602, and the storage barrel 603 is clamped between the two sets of bottom plates 604, and one end of the bottom plate 604 away from the storage barrel 603 is fixedly connected to the guide frame 601, and the movable plate 60 The lower end surface of the movable plate 602 is in contact with the upper end surface of the gear 605. A rotating shaft 606 is installed in the middle of the gear 605. The rotating shaft 606 is rotatably mounted on the base 607. The base 607 is fixedly mounted on the machine 1. A feeding trough 6021 is provided on the movable plate 602. Three sets of arc-shaped racks 2021 for driving the gear 605 are provided at equal angles on the outer ring of the disk body 202. A guide groove 6022 is provided on the lower end surface of the movable plate 602. A pin 6051 is provided on the gear 605 and is located in the guide groove 6022.

[0031] Specifically, since the discharge trough 203 can only place one group of workpieces 7 at a time, the staff needs to cooperate with the device to discharge the workpieces in real time, which not only leads to low efficiency of the staff, but also wastes a lot of manpower. In the initial state, the feeding trough 6021 is located at the loading point, and the feeding trough 6021 is facing a group of discharge troughs 203. The upper end surface of the gear 605 is flush with the upper end surface of the disc body 202. Before grinding the workpiece 7, multiple groups of workpieces 7 can be placed in the storage barrel 603 at one time. When the disc body 202 rotates 120 degrees, the three groups of arc-shaped racks 2021 rotate with the disc body 202. As the arc-shaped racks 2021 rotate, one group of arc-shaped racks 2021 will engage the gear 605 and drive the gear 605 to rotate. The rotating gear 605 drives the pin 6051 to rotate. The pin 6051 drives the movable plate 602 to move through the guide groove 6022, so that the feeding trough 6021 on the movable plate 602 moves toward the bottom of the storage barrel 603 until the feeding trough 6021 moves to the bottom of the storage barrel 603. Under the action of the guide groove 6022, it makes a brief stop, so that the workpiece 7 in the storage barrel 603 falls into the feeding trough 6021, and the rotating gear 605 It plays a supporting role for the workpiece 7, and then the workpiece 7 returns to the initial position along with the feeding trough 6021. At this time, the gear 605 is just staggered with the arc rack 2021, and the workpiece 7 in the feeding trough 6021 automatically falls into the discharge trough 203 on the disk body 202, realizing automatic loading of the workpiece 7. Since the loading mechanism 6 can automatically load the workpiece 7 and can store multiple groups of workpieces 7 at a time, one staff member can provide workpieces 7 to multiple groups of loading mechanisms 6, which not only improves the work efficiency of the staff, but also further improves the automation rate of the device.

[0032] Furthermore, a limiting mechanism 608 is provided between the gear 605 and the base 607. The limiting mechanism 608 includes three groups of tooth blocks 6081, which are distributed at equal angles on the lower end surface of the gear 605, a toothed disc 6082 that engages with the toothed block 6081, a guide column 6083 that is slidingly connected to the toothed disc 6082, and a lower end of the guide column 6083 that is fixedly connected to the base 607. The upper end of the second spring 6084 is tightly attached to the toothed disc 6082. The second spring 6084 and the toothed disc 6082 are both sleeved on the rotating shaft 606.

[0033] Specifically, when the above-mentioned gear 605 rotates, the gear 605 drives the rotating shaft 606 and the three sets of tooth blocks 6081 to rotate together. At the same time, the three sets of tooth blocks 6081 squeeze the tooth grooves on the tooth disc 6082, so that the tooth disc 6082 slides downward along the guide column 6083, and the tooth disc 6082 compresses the second spring 6084 until the three sets of tooth blocks 6081 are engaged with the tooth disc 6082 again under the action of the rebound force of the second spring 6084. When the gear 605 is staggered from the arc-shaped rack 2021, the meshing force between the tooth disc 6082 and the tooth block 6081 prevents the gear 605 from rotating, thereby ensuring that the workpiece 7 in the feed trough 6021 can accurately fall into the discharge trough 203.

[0034] Working principle: put the workpiece 7 into the discharge trough 203 at the loading point, and the two sets of limit blocks 2031 in the discharge trough 203 are engaged with the teeth on the workpiece 7, and then the motor drives the driving column 201 to rotate, and the driving column 201 drives the disc 202 and the workpiece 7 to rotate 120 degrees. Figure 2 The direction indicated by the middle arrow is the rotation direction, so that the workpiece 7 is rotated to the right below the polishing rod 5, and then the polishing rod 5 is driven to rotate by another set of motors, and at the same time, the linear slide mechanism 3 drives the movable seat 4 together with the rotating polishing rod 5 to move toward the inner ring of the workpiece 7, so that the polishing rod 5 polishes the inner ring of the workpiece 7. During this process, the next group of workpieces 7 can be placed in the next group of discharge troughs 203 until the polishing rod 5 finishes polishing the inner ring of the workpiece 7. Then, the polishing rod 5 is withdrawn, and the disc 202 is continued to be driven to rotate, so that the next group of workpieces 7 is rotated to the right below the polishing rod 5. During the process of the polishing rod 5 polishing the next group of workpieces 7, the polished workpieces 7 can be taken out from the corresponding discharge trough 203, and the workpieces 7 to be polished can be placed in the discharge trough 203, and the above operation is repeated in a cycle. When the workpiece 7 is placed in the discharge trough 203, the support frame 2041 supports the workpiece 7. When the disc 202 drives the workpiece 7 to rotate to the bottom of the grinding rod 5, the roller 2043 rolls along the annular surface 1011. After the workpiece 7 is polished, the disc 202 drives the workpiece 7 to continue to rotate 120 degrees. The roller 2043 rolls along the annular surface 1011 to the first inclined surface 1012, and the roller 2043 is squeezed by the first inclined surface 1012, so that the roller 2043 drives the receiving plate 2042 and the support frame 2041 to move toward the axis of the disc 202, and the receiving plate 2042 slides along the guide groove 2032. At the same time, the receiving plate 2042 compresses the first spring 2044. Until the roller 2043 rolls to the intersection of the first inclined surface 1012 and the second inclined surface 1013, during this process, the support frame 2041 releases its support for the workpiece 7, and the workpiece 7 will first fall onto the receiving platform 103. At the same time, the disc 202 drives the workpiece 7 to slide along the receiving platform 103 through the guide groove 2032, so that the workpiece 7 slides onto the conveyor belt mechanism 102, and the workpiece 7 is transported to the next process through the conveyor belt mechanism 102. When the disc 202 continues to rotate, the roller 2043 rolls along the second inclined surface 1013 under the action of the rebound force of the first spring 2044 until the roller 2043 rolls onto the annular surface 1011 again, and the support frame 2041 supports the workpiece 7 again. Before grinding the workpiece 7, multiple groups of workpieces 7 can be placed in the storage barrel 603 at one time. When the disc 202 rotates 120 degrees, the three groups of arc-shaped racks 2021 rotate along with the disc 202. As the arc-shaped racks 2021 rotate, The rotating gear 605 then drives the pinion 6051 to rotate, and the pinion 6051 drives the movable plate 602 to move through the guide groove 6022, so that the feeding chute 6021 on the movable plate 602 moves toward the bottom of the storage barrel 603 until the feeding chute 6021 moves to the bottom of the storage barrel 603. Under the action of the guide groove 6022, it makes a brief stop, so that the workpiece 7 in the storage barrel 603 falls into the feeding chute 6021, and the rotating gear 605 supports the workpiece 7. Then the workpiece 7 returns to the initial position along with the feeding chute 6021. At this time, the gear 605 just staggers the arc-shaped rack 2021, and the workpiece 7 in the feeding chute 6021 automatically falls into the discharge chute 203 on the disc body 202, thereby realizing automatic loading of the workpiece 7. When gear 605 rotates, gear 605 drives the rotating shaft 606 and the three sets of tooth blocks 6081 to rotate together. At the same time, the three sets of tooth blocks 6081 squeeze the tooth grooves on the tooth plate 6082, causing the tooth plate 6082 to slide downward along the guide column 6083, and the tooth plate 6082 compresses the second spring 6084 until the three sets of tooth blocks 6081 are engaged with the tooth plate 6082 again under the action of the rebound force of the second spring 6084. When gear 605 is staggered from the arc-shaped rack 2021, the meshing force between the tooth plate 6082 and the tooth blocks 6081 prevents gear 605 from rotating.
