Description

Technical Field

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

[0002] Gear inner hole processing is an important link in gear manufacturing. When processing the gear inner hole, the gear inner hole processing is divided into rough processing and fine processing. First, the inner hole on the gear is rough processed by a turning device, and then the inner hole is further ground by a grinding device to make the inner hole accuracy meet the assembly requirements.

[0003] The patent with announcement number CN219787690U discloses a gear inner hole grinding device, including a device body, which includes an operating table, a slider, a grinding head, and a positioning assembly. The slider is movably mounted on the operating table, and a motor for driving the grinding head is fixedly mounted on the slider. The positioning assembly includes a mounting table, a positioning box, a cylinder, multiple brackets, and a positioning ring. This solution is provided with a material receiving assembly. This design allows the debris generated by grinding to pass through the leakage trough and fall into the material receiving box for collection. After a certain amount of debris is collected, the material receiving box is held and lifted upward so that the positioning block is no longer stuck in the positioning groove, and then the material receiving box is pulled out from the fixed frame to centrally process the metal debris.

[0004] In the above scheme, before grinding the inner hole of the gear, the gears need to be placed one by one in the positioning box, and then the gears can be ground. Conversely, after the gear grinding is completed, the gears in the positioning box need to be removed and the gears to be ground need to be placed in before the next group of grinding can be carried out. In this process, a lot of time is wasted on taking and placing the gears, which reduces the efficiency of gear grinding. For this reason, the present invention provides a gear inner ring grinding device. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: a gear processing inner ring grinding device described in the present invention includes a machine table, a turntable mechanism is provided on the machine table, a linear slide mechanism is provided on one side of the turntable mechanism, the linear slide mechanism is fixedly mounted on the machine table, a movable seat is installed on the linear slide mechanism, a grinding rod is rotatably mounted on the movable seat, the turntable mechanism includes a driving column, the driving column is rotatably mounted on the machine table, a disk body fixedly mounted on the driving column, a material discharge trough for placing a workpiece is provided on the disk body at equal angles, a bracket for supporting the workpiece is provided at the bottom of the material discharge trough, and two groups of limit blocks for engaging the workpiece are symmetrically arranged in the material discharge trough;

[0007] 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 place 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.

[0008] Preferably, the bracket includes a support frame, the support frame is located at the bottom of the discharge trough, a receiving plate fixedly connected to the support frame, a roller rotatably mounted on the receiving plate, one end of the first spring is in close contact with the support frame, three sets of guide grooves are provided at equal angles on the lower end surface of the disc body, the support frame is slidably connected to the guide groove, the other end of the first spring is in close contact with the inner wall of the guide groove, a guide ring is fixedly mounted on the machine platform, the roller is rotatably connected to the inner ring of the guide ring, the inner ring of the guide ring is composed of an annular surface, a first inclined surface, and a second inclined surface, the machine platform is further provided with a conveyor belt mechanism for conveying workpieces, and a receiving platform is provided on one side of the conveyor belt mechanism;

[0009] Under the coordinated action of the annular surface, the first inclined surface, the second inclined surface, the roller, the first spring, the receiving platform and the conveyor belt mechanism, automatic unloading of the workpiece is achieved, which not only reduces the workload of the staff but also improves the automation rate of the device.

[0010] Preferably, a loading mechanism is further provided on the machine platform, which includes two sets of guide frames, both sets of guide frames are fixedly mounted on the machine platform, and the two sets of guide frames are slidably connected on both sides of the movable plate, a storage barrel for storing workpieces is arranged on the movable plate, the storage barrel is clamped between the two sets of bottom plates, and one end of the bottom plate away from the storage barrel is fixedly connected to the guide frame, the lower end surface of the movable plate is in contact with the upper end surface of the gear, and a rotating shaft is installed in the middle of the gear, the rotating shaft is rotatably mounted on the base, and the base is fixedly mounted on the machine platform, a feeding trough is provided on the movable plate, and three sets of arc-shaped racks for driving the gear are provided at equal angles on the outer ring of the disk, a guide groove is provided on the lower end surface of the movable plate, and a pin shaft is provided on the gear, and the pin shaft is located in the guide groove;

[0011] Since the loading mechanism can automatically load the workpieces and can store multiple groups of workpieces at a time, one worker can provide workpieces to multiple groups of loading mechanisms, which not only improves the work efficiency of the worker, but also further improves the automation rate of the device.

[0012] Preferably, a limiting mechanism is provided between the gear and the base, the limiting mechanism comprising three groups of tooth blocks, the three groups of tooth blocks being distributed at equal angles on the lower end surface of the gear, a toothed disc engaging the toothed blocks, a guide post being slidably connected to the toothed disc, the lower end of the guide post being fixedly connected to the base, the upper end of the second spring being in close contact with the toothed disc, and the second spring and the toothed disc being both sleeved on the rotating shaft;

[0013] 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.

[0014] The beneficial effects of the present invention are as follows:

[0015] 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.

[0016] 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.

[0017] 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

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0031] Example 1: Figure 1 and Figure 2 As shown, a gear processing inner ring grinding device described in an embodiment of the present invention includes a machine table 1, a turntable mechanism 2 is provided on the machine table 1, a linear slide mechanism 3 is provided on one side of the turntable mechanism 2, the linear slide mechanism 3 is fixedly installed on the machine table 1, a movable seat 4 is installed on the linear slide mechanism 3, and 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 is fixedly installed on the driving column 201, and a material discharge trough 203 for placing a workpiece 7 is opened at an equal angle on the disk body 202, a bracket 204 for supporting the workpiece 7 is provided at the bottom of the material discharge trough 203, and two groups of limit blocks 2031 for engaging the workpiece 7 are symmetrically arranged in the material discharge trough 203.

[0032] Specifically, attached Figure 1 The position indicated by the middle arrow is the loading point. In the initial state, a set of discharge troughs 203 is located at the loading point. When the inner ring of the gear needs to be ground, the workpiece 7 is placed in the discharge trough 203 located 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. Then the motor drives the driving column 201 to rotate, and the driving column 201 drives the disc 202 to rotate 120 degrees together with the workpiece 7. Figure 2 The direction indicated by the middle arrow is the direction of rotation, so that the workpiece 7 is rotated to the right below the grinding rod 5, and then the grinding rod 5 is driven to rotate by another set of motors. At the same time, the linear slide mechanism 3 drives the movable seat 4 together with the rotating grinding rod 5 to move toward the inner ring of the workpiece 7, so that the grinding rod 5 grinds the inner ring of the workpiece 7. In this process, the next group of workpieces 7 can be placed in the next group of discharge troughs 203 until the grinding rod 5 finishes grinding the inner ring of the workpiece 7. Then, the grinding rod 5 is withdrawn, and the disk body 202 is continued to be driven to rotate, so that the next group of workpieces 7 is rotated to the right below the grinding rod 5. During the grinding process of the grinding rod 5 on the next group of workpieces 7, the ground workpieces 7 can be taken out from the corresponding discharge trough 203, and the workpieces 7 to be ground can be placed in the discharge trough 203 at the same time, and the above operations are repeated in a cycle. Compared with the prior art, the rotating disc 202 can make the workpieces 7 pass through the loading point and under the grinding rod 5 in turn, so that during the grinding process of the workpieces 7, the staff can simultaneously remove the ground workpieces 7 and place the workpieces 7 to be ground into the discharge trough 203, which saves the time for taking and placing the workpieces 7 and improves the grinding efficiency of the workpieces 7.

[0033] like Figures 3 to 5As shown, the bracket 204 includes a support frame 2041, the support frame 2041 is located at the bottom of the discharge trough 203, a receiving plate 2042 fixedly connected to the support frame 2041, a roller 2043 rotatably installed on the receiving plate 2042, one end of the first spring 2044 is close to the support frame 2041, three groups of guide grooves 2032 are opened at equal angles on the lower end surface of the disk body 202, the support frame 2041 is slidably connected to the guide groove 2032, and the other end of the first spring 2044 is close to the inner wall of the guide groove 2032, a guide ring 101 is fixedly installed on the machine 1, and the roller 2043 is rollingly connected to the inner ring of the guide ring 101, and the inner ring of the guide ring 101 is composed of an annular surface 1011, a first inclined surface 1012, and a second inclined surface 1013. The machine 1 is also provided with a conveyor belt mechanism 102 for conveying the workpiece 7, and a receiving platform 103 is provided on one side of the conveyor belt mechanism 102.

[0034] When the workpiece 7 is put into the discharge trough 203, the support frame 2041 supports the workpiece 7. When the disc 202 drives the workpiece 7 to rotate under the grinding rod 5, the roller 2043 rolls along the annular surface 1011. When 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 the 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 disk 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 disk 202 continues to rotate, under the action of the rebound 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, and the support frame 2041 supports the workpiece 7 again. Under the coordinated 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 platform 103, and the conveyor belt mechanism 102, the automatic unloading of the workpiece 7 is realized, which not only reduces the workload of the staff, but also improves the automation rate of the device.

[0035] Example 2: 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.
