Description

Technical Field

[0001] This invention relates to the field of gear processing and manufacturing technology, and in particular to a dual-station vertical gear honing machine. Background Technology

[0002] High-precision hardened gears are essential mechanical transmission components in automobiles, wind power generation, shipbuilding, machine tools, aerospace, high-speed rail, and other fields. The main purpose of the honing process for hardened gears is to achieve maximum load-bearing capacity and minimum transmission noise. High-precision hardened gear honing is an effective manufacturing technology for achieving maximum load-bearing capacity and minimum transmission noise in high-quality gears. Traditional processing techniques such as hobbing, shaping, shaving, and heat treatment can no longer meet the requirements of high-end equipment in terms of transmission accuracy, transmission noise, and reduced manufacturing costs. Therefore, corresponding hardened gear honing methods have become the leading direction in gear honing manufacturing technology research. The honing process can achieve high dimensional accuracy, shape accuracy, and low tooth surface roughness, and it is highly efficient, low-cost, and produces no tooth surface burns. Therefore, it is widely used in the processing of hardened gears after heat treatment.

[0003] Existing internal gear honing machines typically employ clamping mechanisms at both axial ends of the honing wheel to clamp the gear in order for the gears to mesh with the honing wheel. This results in a honing head with a centrally continuous annular structure. For the honing wheel to rotate within the honing head, a support bearing is required between the honing wheel and the honing head. This support bearing is usually larger than the honing wheel, and to ensure the accuracy of gear honing, the precision requirements for the support bearing are also high. In other words, the support bearings in existing gear honing machines need to simultaneously meet the requirements of large size and high precision. Under the same precision requirements, the larger the bearing, the higher its cost, leading to higher overall and maintenance costs for the gear honing machine. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is: how to provide a dual-station vertical honing machine with reasonable structural design, high processing efficiency, which can meet the processing accuracy requirements and reduce costs.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A dual-station vertical gear honing machine includes a bed and a honing head assembly disposed in the middle of the bed. The back side of the bed has a vertically arranged column extending along the length of the bed. A honing feed assembly is disposed on each side of the honing head assembly. Each honing feed assembly includes a Z-axis support plate and an X-axis support plate. The X-axis support plate is laterally movably mounted on the column via a laterally arranged X-axis feed mechanism and can be moved above the honing head assembly. The Z-axis support plate is vertically and flexibly mounted on the X-axis support plate via a vertically arranged Z-axis feed mechanism. The Z-axis support plate has a vertically arranged gear clamping mechanism with its clamping portion facing downwards. The honing head assembly extends and is suspended below the Z-axis support plate; the honing head assembly includes a honing housing, a vertically arranged circular support cavity inside the honing housing, and a coaxially arranged support hole at the bottom of the support cavity; a coaxially arranged honing cylinder is provided inside the support cavity, and a relatively protruding honing wheel is coaxially mounted inside the honing cylinder, the honing wheel being located at the upper end of the honing cylinder; a coaxially arranged honing shaft is provided at the lower end of the honing cylinder, the honing shaft being rotatably mounted in the support hole via a support bearing; a rotary drive mechanism is connected to the honing cylinder or the honing shaft; the maximum outer diameter of the clamping part of the gear clamping mechanism is smaller than the minimum inner diameter of the honing wheel, and can extend into the honing cylinder.

[0007] Using the above structure, the gear is clamped by a downwardly suspended clamping part of the gear clamping mechanism. Since the maximum outer circle diameter of the clamping part is smaller than the minimum inner diameter of the honing wheel, the clamped gear can be fed downward into the honing cylinder along with the clamping part via the Z-axis feed mechanism, and then engage with the honing wheel for honing. This structure eliminates the need to place the gear clamping mechanism on both sides of the honing wheel, thus eliminating the need for a through-hole annular structure for the honing head. Only a relatively deep honing cylinder is needed to accommodate the insertion length of the clamping part. Simultaneously, the honing cylinder is coaxially positioned within a vertical support cavity, and the lower honing shaft is coaxially mounted on a support hole. Due to the small size of the support hole, the size of the support bearing between the honing shaft and the support hole is also relatively small. Compared to the support bearings of existing honing head structures, the smaller support bearing is less expensive for the same precision requirements, thereby reducing equipment and maintenance costs. In addition, setting the honing cylinder vertically via the honing shaft avoids the bending moment caused by the increase in the axial dimension of the honing cylinder, which is more conducive to ensuring honing accuracy. At the same time, the two sets of honing feed components can work alternately. While one set is performing honing, the other set can load and unload materials, which can greatly improve processing efficiency.

[0008] Furthermore, the gear clamping mechanism includes a honing spindle vertically disposed on the Z-axis support plate, the lower end of which has a headstock portion; a tailstock pad is disposed side by side on one side of the honing spindle, the lower end of which extends downward and is suspended below the Z-axis support plate; the tailstock pad is movably mounted with a tailstock support plate via a vertically disposed tailstock feed mechanism, the lower end of which has a tailstock portion coaxially disposed with the headstock portion on the side facing the honing spindle, and a gear clamping space is formed between the headstock portion and the tailstock portion.

[0009] Furthermore, the tailstock feeding mechanism includes a tailstock guide rail vertically arranged on the tailstock pad, and the tailstock support plate is slidably mounted on the tailstock guide rail via a slider; a vertically arranged lead screw is provided between the tailstock pad and the tailstock support plate, the upper end of the lead screw is drivenly connected to a tailstock drive motor, and the lead screw nut on the lead screw is connected to the tailstock support plate.

[0010] Furthermore, the tailstock pad has a vertically through guide groove on the side facing the honing spindle, the tailstock support plate is located in the guide groove, and the tailstock guide rails are provided between the two sides and the corresponding groove walls.

[0011] Furthermore, the X-axis feed mechanism includes an X-axis bearing support rail and an X-axis auxiliary rail that are horizontally mounted on the column. The X-axis bearing support rail is located at the top of the column; the X-axis auxiliary rail is located on the side of the column facing the honing head assembly; the upper end of the X-axis support plate has a support block protruding towards the column, and the bottom of the support block is mounted on the slider of the X-axis bearing support rail; the side of the X-axis support plate facing the column is mounted on the slider of the X-axis auxiliary rail; and a horizontally arranged linear drive mechanism is provided between the X-axis support plate and the column.

[0012] In this way, the protruding support block forms a "7" shaped structure. An X-bearing support rail is set between the bottom of the support block and the top of the column, so that the weight of the X-axis support plate and the components mounted on it is mainly applied to the column through the support block. This can greatly improve the service life of the X-axis auxiliary guide rail and the X-bearing support rail, and also improve the overall rigidity, which is conducive to ensuring honing accuracy.

[0013] Furthermore, the X-axis support plate has a relatively protruding guide block extending vertically on the side opposite to the column. The Z-axis feed mechanism includes Z-axis guide rails vertically mounted on both sides of the guide block. The Z-axis support plate has support blocks protruding towards the X-axis support plate on both sides in the lateral direction. The opposite sides of the support blocks on both sides are respectively mounted on the sliders of the corresponding Z-axis guide rails. A vertically arranged linear drive mechanism is provided between the Z-axis support plate and the X-axis support plate.

[0014] In this way, the two support blocks of the Z-axis support plate form a "[" shape. On the one hand, it can wrap the two Z-axis guide rails inside, so that the guide rails are in a relatively closed space, which is conducive to improving the working environment of the guide rails. On the other hand, it can make the force of the Z-axis support plate in the front-back direction be limited and supported by the guide rails and the slider width direction, while the force of the Z-axis support plate in the left-right direction is limited and supported by the support block and the guide block, thereby ensuring that the Z-axis support plate can move reliably vertically.

[0015] Furthermore, the linear drive mechanism is a lead screw and nut mechanism, and a drive motor is connected to the lead screw and nut mechanism.

[0016] Furthermore, a vertically arranged balance cylinder is mounted on one side of the X-axis support plate via a support seat, and a push seat is provided on the Z-axis support plate that is vertically opposite to the support seat, with the telescopic rod of the balance cylinder connected to the push seat.

[0017] In this way, by using a balance cylinder to balance and support the weight of the Z-axis support plate and its accessories, the Z-axis will not generate additional errors due to load changes during movement, thereby improving the positioning accuracy of the Z-axis. At the same time, the Z-axis feed mechanism only needs to provide the power required for feeding, without having to overcome the weight of the components themselves, thus reducing the burden on the Z-axis feed mechanism.

[0018] Furthermore, the honing head assembly includes a honing head bracket mounted on the bed, and the two sides of the honing machine housing are rotatably mounted on the honing head bracket via a coaxially arranged swing shaft, the swing shaft being located at the upper end of the honing machine housing; an angle drive mechanism for driving the honing machine housing to rotate around the axis of the swing shaft is provided between the honing machine housing and the honing head bracket.

[0019] In this way, the honing machine housing is rotated around the swing shaft by the tilting drive mechanism, so that the honing cylinder, which is coaxially set in the support cavity of the honing machine housing, also rotates together, thus adapting to different working postures.

[0020] Furthermore, the tilting drive mechanism includes an arc-shaped rack disposed on the honing machine housing, the arc-shaped rack being coaxially disposed with the swing shaft; a tilting drive motor is mounted on the honing head bracket, and the output end of the tilting drive motor is drivenly connected to a tilting drive gear meshing with the arc-shaped rack.

[0021] In this way, the tilt drive motor drives the tilt drive gear to rotate, which in turn drives the arc rack to move around the axis of the swing shaft, thereby causing the honing machine housing to rotate around the axis of the swing shaft.

[0022] In summary, the present invention has the advantages of reasonable structural design, high processing efficiency, and the ability to meet processing accuracy requirements while reducing costs. Attached Figure Description

[0030] The present invention will be further described in detail below with reference to the embodiments.

[0031] In specific implementation: a dual-station vertical gear honing machine, such as Figure 1 As shown, the honing head assembly includes a bed 1 and a honing head assembly 2 disposed in the middle of the bed 1. The back side of the bed 1 has a vertically arranged column 3, which extends along the length of the bed 1. A honing feed assembly is disposed on each side of the honing head assembly 2. The honing feed assembly includes a Z-axis support plate 4 and an X-axis support plate 6. The X-axis support plate 6 is laterally movable on the column 3 through a laterally arranged X-axis feed mechanism and can be moved above the honing head assembly 2. The Z-axis support plate 4 is vertically movable on the X-axis support plate 6 through a vertically arranged Z-axis feed mechanism. The Z-axis support plate 4 has a vertically arranged gear clamping mechanism 5, the clamping part of which extends downward and is suspended below the Z-axis support plate 4.

[0032] like Figures 2-5As shown, the honing head assembly 2 includes a honing head support 21 and a honing housing 22 vertically mounted on the honing head support 21. A circular support cavity 221 is vertically arranged inside the honing housing 22, and the bottom of the support cavity 221 has a coaxially arranged support hole. A honing cylinder 23 is coaxially arranged inside the support cavity 221, and a honing wheel 24 is coaxially mounted inside the honing cylinder 23, with relatively protruding honing wheels. The grinding wheel 24 is located at the upper end of the honing cylinder 23; the lower end of the honing cylinder 23 has a honing shaft 25 coaxially arranged, and the honing shaft 25 is rotatably installed in the support hole through the support bearing 251; a rotary drive mechanism 27 is connected to the honing cylinder 23 or the honing shaft 25; the maximum outer circle diameter of the clamping part of the gear clamping mechanism 5 is smaller than the minimum inner diameter of the honing wheel 24, and can extend into the honing cylinder 23.

[0033] Using the above structure, the gear is clamped by a downwardly suspended clamping part of the gear clamping mechanism. Since the maximum outer circle diameter of the clamping part is smaller than the minimum inner diameter of the honing wheel, the clamped gear can be fed downward into the honing cylinder along with the clamping part via the Z-axis feed mechanism, and then engage with the honing wheel for honing. This structure eliminates the need to place the gear clamping mechanism on both sides of the honing wheel, thus eliminating the need for a through-hole annular structure for the honing head. Only a relatively deep honing cylinder is needed to accommodate the insertion length of the clamping part. Simultaneously, the honing cylinder is coaxially positioned within a vertical support cavity, and the lower honing shaft is coaxially mounted on a support hole. Due to the small size of the support hole, the size of the support bearing between the honing shaft and the support hole is also relatively small. Compared to the support bearings of existing honing head structures, the smaller support bearing is less expensive for the same precision requirements, thereby reducing equipment and maintenance costs. In addition, setting the honing cylinder vertically via the honing shaft avoids the bending moment caused by the increase in the axial dimension of the honing cylinder, which is more conducive to ensuring honing accuracy. At the same time, the two sets of honing feed components can work alternately. While one set is performing honing, the other set can load and unload materials, which can greatly improve processing efficiency.

[0034] In practice, the rotary drive mechanism 27 includes a stator assembly 271 coaxially embedded in the support cavity 221, and a permanent magnet 272 matching the stator assembly 271 is embedded on the outer wall of the honing cylinder 23.

[0035] In this way, on the one hand, the entire honing cylinder can be used as the rotor part of the motor to drive the honing cylinder to rotate; on the other hand, the magnetic force between the stator assembly and the permanent magnet can be used to keep the honing cylinder coaxially supported in the support cavity, so that the coaxial accuracy of the honing cylinder is higher during the rotation process.

[0036] like Figure 4 and Figure 5As shown, the honing machine housing 22 is rotatably mounted on the honing head support 21 via coaxially arranged swing shafts 222 on both sides, with the swing shafts 222 located at the upper end of the honing machine housing 22. An angle drive mechanism 28 is provided between the honing machine housing 22 and the honing head support 21 to drive the honing machine housing 22 to rotate around the axis of the swing shafts 222. Thus, by rotating the honing machine housing around the swing shafts via the angle drive mechanism, the honing cylinder, coaxially arranged within the support cavity of the honing machine housing, also rotates, thereby adapting to different working postures.

[0037] Specifically, such as Figure 3 and Figure 5 As shown, the tilt drive mechanism 28 includes an arc-shaped rack 281 mounted on the honing machine housing 22, the arc-shaped rack 281 being coaxially arranged with the swing shaft 222; a tilt drive motor 282 is mounted on the honing head bracket 21, and the output end of the tilt drive motor 282 is connected to a tilt drive gear 283 meshing with the arc-shaped rack 281. Thus, the tilt drive motor drives the tilt drive gear to rotate, causing the arc-shaped rack to move around the axis of the swing shaft, thereby causing the entire honing machine housing to rotate around the axis of the swing shaft.

[0038] In this embodiment, the inner cavity of the honing cylinder 23 has a grinding wheel groove arranged in a ring along the circumference. The grinding wheel groove is located at the top of the honing wheel 23 and extends upward. The diameter of the grinding wheel groove matches the outer diameter of the honing wheel 24, and its width is smaller than the width of the honing wheel 24. A grinding wheel pressure ring 29 is detachably installed on the top of the honing wheel 23. The honing wheel 24 is disposed in the grinding wheel groove, and the grinding wheel pressure ring 29 presses against the honing wheel 24. An annular oil receiving plate 291 is installed in the support cavity 221. The inner side of the oil receiving plate 291 has a first oil-blocking ring 292 extending upward, and the first oil-blocking ring 292 is disposed close to the honing cylinder 23. The outer side of the grinding wheel pressure ring 29 has a downwardly extending second oil baffle ring 293, and the upper end of the first oil baffle ring 292 is located between the honing cylinder 23 and the second oil baffle ring 293. The honing shaft 25 has a through-hole for unloading in the middle.

[0039] To enable the honing shaft 25 to rotate more stably, a plurality of support bearings 251 are provided between the honing shaft 25 and the support hole; a rotary encoder is provided between the honing machine housing 22 and the honing cylinder 23 or the honing shaft 25.

[0040] like Figures 6-8As shown, the gear clamping mechanism 5 includes a honing spindle 51 vertically arranged on the Z-axis support plate 4, with a headstock portion at the lower end of the honing spindle 51; a tailstock pad 52 is arranged side by side on one side of the honing spindle 51, with the lower end of the tailstock pad 52 extending downward and suspended below the Z-axis support plate 4; a tailstock support plate 53 is mounted on the tailstock pad 52 via a vertically arranged tailstock feed mechanism, with a tailstock portion coaxially arranged with the headstock portion on the side of the lower end of the tailstock support plate 53 facing the honing spindle 51, and a gear clamping space is formed between the headstock portion and the tailstock portion.

[0041] like Figure 8 As shown, the tailstock feeding mechanism includes a tailstock guide rail 54 vertically mounted on the tailstock pad 52, and a tailstock support plate 53 slidably mounted on the tailstock guide rail 54 via a slider. A vertically arranged lead screw 55 is located between the tailstock pad 52 and the tailstock support plate 53. A tailstock drive motor 56 is connected to the upper end of the lead screw 55, and a lead screw nut on the lead screw 55 is connected to the tailstock support plate 53. Specifically, the tailstock pad 52 has a vertically through guide groove on the side facing the honing spindle 51, the tailstock support plate 53 is located within the guide groove, and the tailstock guide rail 54 is arranged between its two sides and the corresponding groove walls.

[0042] In implementation, the X-axis feed mechanism includes an X-axis bearing support rail 61 and an X-axis auxiliary guide rail 62, which are horizontally mounted on the column 3. The X-axis bearing support rail 61 is located at the top of the column 3; the X-axis auxiliary guide rail 62 is located on the side of the column 3 facing the honing head assembly 2; the upper end of the X-axis support plate 4 has a support block 63 protruding towards the column 3, and the bottom of the support block 63 is mounted on the slider of the X-axis bearing support rail 61; the side of the X-axis support plate 4 facing the column 3 is mounted on the slider of the X-axis auxiliary guide rail 62; and a horizontally arranged linear drive mechanism is provided between the X-axis support plate 6 and the column 3. In this way, the protruding support block forms a "7" shaped structure. An X-bearing support rail is set between the bottom of the support block and the top of the column, so that the weight of the X-axis support plate and the components mounted on it is mainly applied to the column through the support block. This can greatly improve the service life of the X-axis auxiliary guide rail and the X-bearing support rail, and also improve the overall rigidity, which is conducive to ensuring honing accuracy.

[0043] In this embodiment, the X-axis support plate 6 has a relatively protruding guide block extending vertically on the side opposite to the column 3. The Z-axis feed mechanism includes Z-axis guide rails 41 vertically mounted on both sides of the guide block. The Z-axis support plate 4 has support blocks 42 protruding towards the X-axis support plate 6 on both sides in the lateral direction. The opposite sides of the support blocks 42 are respectively mounted on the sliders of the corresponding Z-axis guide rails 41. A vertically arranged linear drive mechanism is provided between the Z-axis support plate 4 and the X-axis support plate 6. In this way, the two support blocks of the Z-axis support plate form a "[" shape. On the one hand, it can wrap the two Z-axis guide rails inside, so that the guide rails are in a relatively closed space, which is beneficial to improving the working environment of the guide rails. On the other hand, the force of the Z-axis support plate in the front-back direction is limited and supported by the guide rails and the slider in the width direction, while the force of the Z-axis support plate in the left-right direction is limited and supported by the support blocks and the guide blocks, thereby ensuring that the Z-axis support plate can move reliably vertically. The linear drive mechanism is a lead screw and nut mechanism (not shown in the figure), and a drive motor (not shown in the figure) is connected to the lead screw and nut mechanism.

[0044] In implementation, a vertically positioned balance cylinder 7 is mounted on one side of the X-axis support plate 6 via a support base. The Z-axis support plate 4 has a push seat vertically opposite the support base, and the telescopic rod of the balance cylinder is connected to the push seat. In this way, the balance cylinder provides balanced support for the weight of the Z-axis support plate and its accessories, preventing additional errors caused by load changes during Z-axis movement, thereby improving the positioning accuracy of the Z-axis. Simultaneously, the Z-axis feed mechanism only needs to provide the power required for feeding, without needing to overcome the weight of the components themselves, thus reducing the burden on the Z-axis feed mechanism.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
