Description

Technical Field

[0001] This invention belongs to the field of gear processing technology, specifically a gear inner ring grinding device. Background Technology

[0002] Gear inner ring machining is an important part of gear manufacturing. Gear inner ring machining can be divided into rough machining and finish machining. First, the inner ring on the gear is rough machined by a turning device, and then the inner ring is further ground by a grinding device to make the inner hole meet the assembly requirements.

[0003] Currently, when grinding the inner ring of a gear, the grinding device first needs to clamp the gear using a clamping mechanism. Then, a telescopic mechanism drives the grinding rod to extend and retract within the inner ring of the gear. The grinding rod repeatedly acts on the inner ring of the gear during its extension and retraction, thereby achieving the grinding of the inner ring. However, to ensure that the grinding rod can smoothly grind the inner ring of the gear, the clamping position of the gear needs to be repeatedly adjusted during the initial clamping process to ensure that the axis of the inner ring of the gear is collinear with the axis of the grinding rod. Only in this way can the grinding rod smoothly grind the inner ring of the gear. It is evident that the clamping steps before grinding the inner ring of the gear in the existing technology are cumbersome and inconvenient, resulting in low grinding efficiency. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a gear inner ring grinding device.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A gear inner ring grinding device includes a processing table, a first drive assembly, a telescopic grinding assembly, a flexible actuation assembly, a plug-in limiting assembly, and a second drive assembly. A vertical plate is fixedly installed at one end of the upper part of the processing table, and the telescopic grinding assembly is installed on one side of the vertical plate. The first drive assembly is mounted on the side wall of the upright plate and is used to drive the telescopic grinding assembly to rotate. The second drive assembly is located at the end of the processing table away from the vertical plate, and is used to drive the telescopic grinding assembly to extend, so that the telescopic grinding assembly supports the gear and contacts the inner ring of the gear. The plug-in limiting component and the flexible actuating component are disposed on the side of the telescopic grinding component. After the telescopic grinding assembly contacts the inner ring of the gear, the flexible actuating assembly is used to actuate the gear, so that the plug-in limiting assembly is inserted between two adjacent sets of teeth of the gear.

[0006] As a further improvement of the present invention: the first driving component includes a first motor and a first rotating shaft. The first motor is fixedly mounted on the side wall of the upright plate, and the first rotating shaft is mounted on the output end of the first motor. The rod-shaped grinding assembly includes a grinding rod, a first diagonal brace, and a second diagonal brace. The grinding rods are provided in several groups, and the grinding rods are arranged in a ring at intervals on the outside of the first rotating shaft. The grinding rods are distributed along the length of the first rotating shaft. One end of each group of grinding rods is hinged to the first rotating shaft through a group of first diagonal braces, and the other end of each group of grinding rods is hinged to the first rotating shaft through a group of second diagonal braces.

[0007] As a further improvement of the present invention: a sliding sleeve is fitted at the end of the first rotating shaft away from the first motor, and the second diagonal support rod at the other end of the grinding rod is hinged to the outer wall of the sliding sleeve. The second drive assembly includes a pressure plate and a hydraulic rod, the hydraulic rod being fixedly installed at the bottom of the processing table, and the pressure plate being disposed at the output end of the hydraulic rod.

[0008] As a further improvement of the present invention: a positioning seat is fixedly provided at the bottom of the processing table, and a guide rod is fixedly provided on the side wall of the pressure plate. The guide rod passes through the positioning seat and is movably engaged with the positioning seat.

[0009] As a further improvement of the present invention: a first elastic element is also provided inside the sliding sleeve, one end of the first elastic element is connected to the inner wall of the sliding sleeve, and the other end is connected to the end of the first rotating shaft, for providing elastic support for the sliding sleeve.

[0010] As a further improvement of the present invention: a horizontal plate is fixedly disposed on the side wall of the upright plate; the plug-in limiting assembly includes a plug rod, an annular stop block, and a third elastic element; the plug rod passes through the horizontal plate and is movably engaged with the horizontal plate; the annular stop block is fixedly disposed outside the plug rod; one end of the third elastic element is connected to the horizontal plate, and the other end is connected to the annular stop block, for providing elastic support for the plug rod. The flexible actuation component includes a second motor, a second rotating shaft, and an airbag. The second motor is fixedly installed on the side wall of the upright plate, the second rotating shaft is located at the output end of the second motor, and the airbag is located outside the second rotating shaft.

[0011] As a further improvement of the present invention: the second rotating shaft is hollow inside, and a second through hole is formed on the side wall of the second rotating shaft in the region inside the airbag; a support block is fixedly installed in the inner cavity of the second rotating shaft, and a first through hole is formed on the support block. A piston rod is movably inserted into the end of the second rotating shaft away from the second motor. The piston rod is connected to the support block by a second elastic element, which provides elastic support for the piston rod.

[0012] As a further improvement of the present invention: a first limiting rod is fixedly provided on the side wall of the upright plate, and a second limiting rod is fixedly provided on the side wall of the pressing plate.

[0013] As a further improvement of the present invention: the plug-in limiting components are arranged in several groups at intervals along the length of the horizontal plate, and the airbags are distributed in a columnar shape along the length of the second rotating shaft.

[0014] Compared with the prior art, the beneficial effects of the present invention are: In this embodiment of the invention, initially, the telescopic grinding component is in a retracted state. When grinding is required on the inner ring of the gear, the gear can be fitted onto the outside of the telescopic grinding component. Then, the second drive component drives the telescopic grinding component to unfold, thereby supporting the gear and contacting the inner ring of the gear. At this time, there are two states between the gear teeth and the plug-in limiting component: one is that the plug-in limiting component is directly inserted between two adjacent sets of teeth of the gear, and the plug-in limiting component directly limits the gear; the other is that the plug-in limiting component abuts against one tooth of the gear, and the gear cannot complete the limiting. Therefore, after the telescopic grinding component contacts the inner ring of the gear, the gear can be moved using the flexible actuating component. If the gear and the telescopic plug-in component are in the first state, then... The gear cannot rotate under the fluctuation of the flexible actuation component and remains in a limited position. If the gear and the telescopic plug-in component are in the second state, the gear can rotate adaptively under the fluctuation of the flexible actuation component. After the gear rotates a certain angle, a tooth that abuts against the telescopic plug-in component is misaligned with the telescopic plug-in component. Then, the telescopic plug-in component smoothly inserts into two adjacent sets of tooth components, thereby completing the gear's limiting position. After the gear is limited, the first drive component drives the unfolded rod-shaped grinding component to rotate against the inner ring of the gear, thereby grinding the inner ring of the gear. Compared with the existing technology, when grinding the inner ring of the gear, the gear can be automatically limited without excessive adjustment of the gear's clamping position, thereby improving grinding efficiency.

Detailed Implementation

[0016] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0017] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0018] Please see Figure 1 as well as Figure 2This embodiment provides a gear inner ring grinding device, including a processing table 10, a first drive assembly 20, a telescopic grinding assembly 30, a flexible actuating assembly 40, a plug-in limiting assembly 50, and a second drive assembly 60. A vertical plate 101 is fixedly mounted on one end of the upper part of the processing table 10. The telescopic grinding assembly 30 is disposed on one side of the vertical plate 101. The first drive assembly 20 is mounted on the side wall of the vertical plate 10 to drive the telescopic grinding assembly 30 to rotate. The second drive assembly 60 is disposed on... At the end of the processing table 10 away from the vertical plate 101, the telescopic grinding assembly 30 is extended to support the gear and make it contact the inner ring of the gear. The plug-in limiting assembly 50 and the flexible actuating assembly 40 are disposed on the side of the telescopic grinding assembly 30. After the telescopic grinding assembly 30 contacts the inner ring of the gear, the flexible actuating assembly 40 is used to actuate the gear so that the plug-in limiting assembly 50 is inserted between two adjacent sets of teeth of the gear.

[0019] Initially, the telescopic grinding component 30 is in a retracted state. When grinding is required on the inner ring of the gear, the gear can be fitted onto the outside of the telescopic grinding component 30. Then, the second drive component 60 drives the telescopic grinding component 30 to unfold, thereby supporting the gear and contacting the inner ring of the gear. At this time, there are two states between the gear teeth and the plug-in limiting component 50: one is that the plug-in limiting component 50 is directly inserted between two adjacent sets of teeth of the gear, and the plug-in limiting component 50 directly limits the gear; the other is that the plug-in limiting component 50 abuts against one of the teeth of the gear, and the gear cannot be limited. Therefore, after the telescopic grinding component 30 contacts the inner ring of the gear, the flexible actuation component 40 can be used to actuate it. If the gear and the telescopic plug-in assembly 50 are in the first state, the gear cannot rotate under the fluctuation of the flexible actuation assembly 40 and remains in a limited position. If the gear and the telescopic plug-in assembly 50 are in the second state, the gear can rotate adaptively under the fluctuation of the flexible actuation assembly 40. After the gear rotates a certain angle, a tooth that abuts against the telescopic plug-in assembly 50 is misaligned with the telescopic plug-in assembly 50. Then, the telescopic plug-in assembly 50 smoothly inserts into two adjacent sets of tooth assemblies, thereby completing the limiting of the gear. After the gear is limited, the first drive assembly 20 drives the unfolded rod-shaped grinding assembly 30 to rotate against the inner ring of the gear, thereby grinding the inner ring of the gear.

[0020] Please see Figure 1 , Figure 3 as well as Figure 4In one embodiment, the first drive assembly 20 includes a first motor 201 and a first rotating shaft 202. The first motor 201 is fixedly mounted on the side wall of the upright plate 101, and the first rotating shaft 202 is mounted on the output end of the first motor 201. The rod-shaped grinding assembly 30 includes a grinding rod 301, a first diagonal brace 302, and a second diagonal brace 303. The grinding rod 301 is provided in several groups, and the several grinding rods 301 are arranged in a ring at intervals on the outside of the first rotating shaft 202. The several grinding rods 301 are distributed along the length direction of the first rotating shaft 202. One end of each group of grinding rods 301 is hinged to the first rotating shaft 202 through a group of first diagonal braces 302, and the other end of each group of grinding rods 301 is hinged to the first rotating shaft 202 through a group of second diagonal braces 303.

[0021] Initially, several grinding rods 301 are positioned close to the first rotating shaft 202 on the outside of the shaft. When grinding is required on the inner ring of the gear, the gear can be inserted onto the outside of the grinding rods 301 from the end of the first rotating shaft 202 away from the first motor 201. Subsequently, the second drive assembly 60 drives the grinding rods 301 to move away from the first rotating shaft 202 simultaneously, thereby simultaneously supporting the gear and contacting the inner ring of the gear. During this process, the first diagonal support rod 302 and the second diagonal support rod 303 rotate adaptively. Then, the first motor 201 is started, and the first motor 201 drives the first rotating shaft 202 to rotate. The first rotating shaft 202 drives the grinding rods 301 to rotate through the first diagonal support rod 302 and the second diagonal support rod 303. When the grinding rods 301 rotate, they act on the inner ring of the gear, thereby performing grinding on the inner ring of the gear.

[0022] Please see Figure 1 , Figure 2 as well as Figure 4 In one embodiment, a sliding sleeve 203 is fitted onto the end of the first rotating shaft 202 away from the first motor 201, and the second diagonal brace 303 at the other end of the grinding rod 301 is hinged to the outer wall of the sliding sleeve 203. The second drive assembly 60 includes a pressure plate 601 and a hydraulic rod 604. The hydraulic rod 604 is fixedly installed at the bottom of the processing table 10, and the pressure plate 601 is disposed at the output end of the hydraulic rod 604.

[0023] After the gear is sleeved on the outside of several grinding rods 301, the hydraulic rod 604 drives the pressure plate 601 to move. When the pressure plate 601 moves, it acts on the sliding sleeve 203, causing the sliding sleeve 203 to slide relative to the first rotating shaft 202. When the sliding sleeve 203 slides, it pushes the second inclined support rod 303 to rotate. When the second inclined support rod 303 rotates, it pushes the grinding rod 301, causing the grinding rod 301 to move away from the first rotating shaft 202, thereby supporting the gear and acting on the inner ring of the gear.

[0024] Please see Figure 2 In one embodiment, a positioning seat 104 is fixedly provided at the bottom of the processing table 10, and a guide rod 603 is fixedly provided on the side wall of the pressure plate 601. The guide rod 603 passes through the positioning seat 104 and is movably engaged with the positioning seat 104.

[0025] The movable cooperation between the guide rod 603 and the positioning seat 104 can provide guidance for the movement of the pressure plate 601, so that the pressure plate 601 can move smoothly.

[0026] Please see Figure 4 In one embodiment, a first elastic element 204 is further provided inside the sliding sleeve 203. One end of the first elastic element 204 is connected to the inner wall of the sliding sleeve 203, and the other end is connected to the end of the first rotating shaft 202, for providing elastic support to the sliding sleeve 203.

[0027] When the hydraulic rod 604 drives the pressure plate 601 to move, causing the pressure plate 601 to push the sliding sleeve 203 to slide relative to the first rotating shaft 202, the first elastic element 204 is compressed by force. After the inner ring of the gear is polished, the hydraulic rod 604 drives the pressure plate 601 to move in the opposite direction. The first elastic element 204 pushes the sliding sleeve 203, causing the sliding sleeve 203 to slide in the opposite direction relative to the first rotating shaft 202. When the sliding sleeve 203 slides in the opposite direction, it pulls the second diagonal support rod 303, causing the second diagonal support rod 303 to rotate in the opposite direction. This causes the polishing rod 301 to approach the first rotating shaft 202 and separate from the inner ring of the gear. Then, the gear can be removed from the end of the first rotating shaft 202 away from the first motor 201.

[0028] Please see Figure 1 In one embodiment, a horizontal plate 102 is fixedly disposed on the side wall of the upright plate 101. The plug-in limiting component 50 includes a plug rod 501, an annular stop block 502, and a third elastic element 503. The plug rod 501 passes through the horizontal plate 102 and is movably engaged with the horizontal plate 102. The annular stop block 502 is fixedly disposed outside the plug rod 501. One end of the third elastic element 503 is connected to the horizontal plate 102, and the other end is connected to the annular stop block 502, for providing elastic support for the plug rod 501. The flexible actuation component 40 includes a second motor 401, a second rotating shaft 402, and an airbag 403. The second motor 401 is fixedly installed on the side wall of the upright plate 101. The second rotating shaft 402 is disposed at the output end of the second motor 401. The airbag 403 is disposed outside the second rotating shaft 402.

[0029] After several grinding rods 301 unfold and support the gear, one end of the insert rod 501 may be directly inserted between two adjacent sets of teeth on the gear, thus directly limiting the gear. Alternatively, one end of the insert rod 501 may abut against a set of teeth on the gear. In this case, the second motor 401 is activated, driving the second rotating shaft 402 to rotate, which in turn drives the airbag 403 to rotate. When the airbag 403 rotates, it acts on the gear. If one end of the insert rod 501 is directly inserted between two adjacent sets of teeth on the gear, the airbag 403 cannot move the gear, and the gear remains stationary. Conversely, if one end of the insert rod 501 is not directly inserted between two adjacent sets of teeth on the gear, the airbag 403 cannot move the gear, and the gear remains stationary. If one end of the insert rod 501 abuts against a set of teeth of the gear, the airbag 403 can actuate the gear to make it rotate. When the gear rotates, the insert rod 501 is disengaged from the abutting teeth. Then, the third elastic element 503 pushes the insert rod 501 to move relative to the cross plate 102. One end of the insert rod 501 is inserted between two sets of teeth of the gear to limit the gear. After the gear is limited, the first motor 201 drives the first rotating shaft 202 to rotate, which in turn drives several grinding rods 301 to rotate against the inner ring of the gear to achieve the grinding treatment of the inner ring of the gear.

[0030] When the airbag 303 rotates and thus actuates the gear, a certain degree of contact needs to be maintained between the airbag 303 and the gear. Therefore, when the gear is inserted from the end of the first shaft 202 away from the first motor 201 onto the outside of several grinding rods 301, the airbag 303 may restrict the insertion process of the gear to some extent. Based on this, please refer to... Figure 1 as well as Figure 5 In one embodiment, the second rotating shaft 402 is hollow inside, and a second through hole 408 is provided on the side wall of the second rotating shaft 402 in the region inside the airbag 403. A support block 406 is fixedly provided in the inner cavity of the second rotating shaft 402, and a first through hole 407 is provided on the support block 406. A piston rod 404 is movably inserted into the end of the second rotating shaft 402 away from the second motor 401. The piston rod 404 is connected to the support block 406 through a second elastic member 405, which provides elastic support for the piston rod 404.

[0031] Initially, the airbag 403 is in a retracted state outside the second rotating shaft 402, so that there is sufficient distance between the airbag 403 and the grinding rod 301 for the gear to engage. After the gear engages the outside of the grinding rod 301, the hydraulic rod 604 drives the pressure plate 601 to move, causing the pressure plate 601 to press against the sliding sleeve 203, thereby pushing the sliding sleeve 203 to move the grinding rod 301 away from the second rotating shaft 202 and thus supporting the gear. During the movement, the pressure plate 601 can also press against the piston rod 404, causing the piston rod 404 to move into the inner cavity of the second rotating shaft 402. When the piston rod 404 moves, it forces the air inside the second rotating shaft 402 through the first through hole 407 and the second through hole 408 to the airbag 402. Inside the airbag 403, the airbag 403 is inflated. When the airbag 403 inflates, it maintains a certain degree of contact with the gear so that when the second motor 401 drives the airbag 403 to rotate, the airbag 403 can smoothly move against the gear. After the inner ring of the gear is polished, as the hydraulic rod 604 drives the pressure plate 601 to move in the opposite direction, the second elastic element 405 pushes the piston rod 404 to move the piston rod 404 to the outside of the second rotating shaft 402, thereby drawing the air inside the airbag 403 through the second through hole 408 into the inner cavity of the second rotating shaft 402, causing the airbag 403 to contract and separate from the gear. Then the gear can be removed from the end of the first rotating shaft 202 away from the first motor 201.

[0032] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4 In one embodiment, a first limiting rod 103 is fixedly provided on the side wall of the upright plate 101, and a second limiting rod 602 is fixedly provided on the side wall of the pressing plate 601.

[0033] When the pressure plate 601 moves, the pressure plate 601 can drive the second limiting rod 602 to move synchronously. When the grinding rods 301 support the gear and contact the inner ring of the gear, the second limiting rod 602 and the first limiting rod 103 act on the opposite sides of the gear respectively, thereby limiting the gear axially. This prevents the gear from moving axially along the grinding rods 301 during the grinding process of the grinding rods 301 rotating, and prevents the insert rod 501 from being removed between two adjacent sets of teeth, which would prevent the gear from being limited. This ensures that the inner ring of the gear can be ground smoothly.

[0034] Please see Figure 1 as well as Figure 2In one embodiment, several sets of plug-in limiting components 50 are arranged sequentially at intervals along the length of the horizontal plate 102, and the airbags 403 are distributed in a columnar shape along the length of the second rotating shaft 402. In this way, several sets of gears, the same number as the plug-in limiting components 50, can be simultaneously fitted onto the outside of several grinding rods 301. With the help of the columnar airbags 403 for the synchronous turning action of several gears, several gears can be synchronously limited by several plug-in limiting components 50. Subsequently, during the rotation of several grinding rods 301, the inner rings of several gears can be ground simultaneously, thereby improving the grinding efficiency of the inner rings of the gears.

[0035] In one embodiment, the first elastic element 204, the second elastic element 405, and the third elastic element 503 can be springs or metal sheets, and there is no limitation here.

[0036] In this embodiment of the invention, initially, the telescopic grinding component 30 is in a retracted state. When grinding is required on the inner ring of the gear, the gear can be fitted onto the outside of the telescopic grinding component 30. Then, the second drive component 60 drives the telescopic grinding component 30 to unfold, thereby supporting the gear and contacting the inner ring of the gear. At this time, there are two states between the gear teeth and the plug-in limiting component 50: one is that the plug-in limiting component 50 is directly inserted between two adjacent sets of teeth of the gear, and the plug-in limiting component 50 directly limits the gear; the other is that the plug-in limiting component 50 abuts against one of the teeth of the gear, and the gear cannot be limited. Therefore, after the telescopic grinding component 30 contacts the inner ring of the gear, the gear can be actuated by the flexible actuating component 40. If the gear and the telescopic plug-in component 50 are in the first state... In the first state, the gear cannot rotate under the fluctuation of the flexible actuation component 40, and the gear remains in a limited position. If the gear and the telescopic insertion component 50 are in the second state, the gear can rotate adaptively under the fluctuation of the flexible actuation component 40. After the gear rotates a certain angle, a tooth that abuts against the telescopic insertion component 50 is misaligned with the telescopic insertion component 50. Then, the telescopic insertion component 50 smoothly inserts into two adjacent sets of tooth components, thereby completing the gear's limiting position. After the gear is limited, the first drive component 20 drives the unfolded rod-shaped grinding component 30 to rotate against the inner ring of the gear, thereby grinding the inner ring of the gear. Compared with the prior art, when grinding the inner ring of the gear, the gear can be automatically limited, without needing to make too many adjustments to the clamping position of the gear, thereby improving the grinding efficiency.

[0037] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
