Description

Technical Field

[0001] This application relates to the field of end face turning apparatus technology, and in particular to an end face turning apparatus for a planetary gear shaft of a wheel-side reducer. Background Technology

[0002] As a core transmission component in the drive axle of engineering machinery (such as mining dump trucks, loaders, excavators, etc.), the end face accuracy of the planetary gear shafts in wheel-side reducers directly affects the axial movement and load distribution uniformity of the gear meshing. Planetary gear shafts are typically multiple shafts evenly distributed on a planetary carrier, requiring all shaft end faces to be machined in a single setup, with the flatness and perpendicularity of the end faces controlled within a high tolerance range. However, existing turning equipment still has the following shortcomings in terms of clamping efficiency, automation level and process continuity: Currently, the turning of planetary gear shaft end faces in the industry mostly adopts a general lathe with a combination of faceplate, bending plate and clamping plate for manual clamping. Operators need to adjust the position of the clamping plate and apply clamping force one by one. Not only is the clamping auxiliary time long, but it is also difficult to ensure that the clamping force on each shaft is consistent. Uneven clamping force can easily cause the workpiece end face to tilt relative to the positioning reference, thus affecting the dimensional stability of the end face turning. Some solutions use hydraulic or pneumatic clamping, which can improve the consistency of clamping force, but requires an external power source and pipeline, the system is complex and costly, and maintenance is inconvenient. Furthermore, planetary gear shafts are relatively heavy, resulting in high labor intensity during loading and unloading operations. Existing solutions partially employ manual handling combined with simple inclined plate feeders. However, when multiple shafts slide down simultaneously during inclined plate feeding, the combined impact energy can easily damage the positioning mechanism. Moreover, the loading and unloading actions are separated, making it impossible to utilize the machine tool's own feed and retraction motions as driving forces, leading to a high proportion of auxiliary time and hindering efficient single-cycle assembly line operations. Therefore, improvements to existing technologies are necessary. Summary of the Invention

[0003] Therefore, it is necessary to provide a turning device for the end face of the planetary gear shaft of a wheel-side reducer to address the above-mentioned technical problems.

[0004] To address the aforementioned problems, this invention provides a technical solution for a turning device for the end face of a planetary gear shaft in a wheel-side reducer: A turning device for the end face of a planetary gear shaft of a wheel-side reducer includes a lathe base, a rotary cover at the upper end of the lathe base, a longitudinal feed box at the upper end of the lathe base, a synchronous automatic locking mechanism on the rotary cover, the synchronous automatic locking mechanism including a sector-shaped clamping block and a moving frame, a plurality of sector-shaped clamping blocks arranged in a ring on the inner wall of the rotary cover, an arc-shaped clamping groove on the side of the sector-shaped clamping block near the center of the rotary cover, and a follow-up locking assembly on the lathe base; An auxiliary loading and unloading mechanism is provided at the upper end of the lathe base. The auxiliary loading and unloading mechanism includes two clamping cylinders, which are located above the turning area of ​​the lathe base.

[0005] Preferably, the synchronous automatic locking mechanism further includes movable rods. Each of the fan-shaped clamping blocks has multiple movable rods fixedly installed on the side away from the center of the rotating cover. One end of each of the movable rods is fixedly installed with a drive plate. The end of the drive plate away from the fan-shaped clamping block is fixedly installed with an inclined wheel frame. Rollers are installed inside the highest and lowest points of the inclined plane of the inclined wheel frame through bearings. The rollers can drive the fan-shaped clamping block to slide in the axial direction of the movable rod through the movable rod, which can improve the clamping accuracy.

[0006] Preferably, a rubber frame is provided between the drive plate and the rotary cover, and a return spring is provided on the outer side of each movable rod. One end of the return spring is fixedly connected to the groove of the rotary cover, and the other end of the return spring is fixedly connected to the drive plate. During the feeding process of the wedge cover, the drive plate compresses the return spring. When the wedge cover is reset, the return spring can drive the drive plate to return to the predetermined position through its elastic force.

[0007] Preferably, two guide rod frames symmetrically distributed around the rotary cover are fixedly installed on the upper end of the lathe base. A movable frame is slidably connected to the outer sides of the two guide rod frames. A wedge-shaped cover is installed inside the movable frame through bearings. The inner inclined surface of the wedge-shaped cover contacts the roller. The wedge-shaped cover can move along with the movable frame. During the movement, the contact between the inclined surface and the roller can drive the roller to move downward. At the same time, the wedge-shaped cover can rotate along with the rotary cover.

[0008] Preferably, the follow-up locking assembly includes a drive rack. The drive rack is fixedly installed at the lower end of the longitudinal feed box near the rotary cover. A fixed shaft is fixedly installed at the upper end of the lathe base. A rotating tube is installed on the outer side of the fixed shaft through a bearing. An incomplete gear is fixedly installed on the lower outer side of the rotating tube. The incomplete gear meshes with the drive rack. During movement, the drive rack can drive the incomplete gear to rotate by meshing with it. When it moves to the toothless position, the rotational force applied to the rotating tube can be stopped, thus completing the movement of the moving frame.

[0009] Preferably, a swing frame is fixedly installed on the upper outer side of the rotating tube, and a tie rod is hinged inside the swing frame. A hinge frame is fixedly installed on the lower front side of the moving frame, and the tie rod is hinged inside the hinge frame. During the rotation of the swing frame, the tie rod can drive the moving frame to move along the axis of the guide rod frame.

[0010] Preferably, a guide frame is fixedly installed on the upper end of the lathe base, a guide post is fixedly installed inside the guide frame, a guide groove is opened on the side of the drive rack away from the tooth groove, the drive rack is slidably connected inside the guide frame, and the guide post is slidably connected inside the guide groove on the back of the drive rack. The guide post and the guide frame can guide the movement of the drive rack.

[0011] Preferably, the auxiliary loading and unloading mechanism further includes a gantry frame. A movable box is provided on the outer side of the adjusting end of the gantry frame. Two lifting cylinders are fixedly installed on the inner side of the movable box. Each lifting cylinder is equipped with a clamping cylinder at its lower end. Two grippers are provided below the clamping cylinders. A loading conveyor belt is provided in the middle of the upper end of the lathe base. A slant feed plate is fixedly installed on the upper end of the lathe base. A drive mechanism is provided inside the frame of the loading conveyor belt. The workpiece after turning can be loaded through the conveyor belt. The two clamping cylinders can simultaneously clamp the unprocessed workpiece shaft while the other clamping cylinder is placing the machined workpiece shaft.

[0012] Preferably, a spindle box is fixedly installed on the upper end of the lathe base, the rotary cover is fixedly installed on the outside of the rotating shaft of the spindle box, a mounting column is fixedly installed on the upper right side of the lathe base, and a control panel is installed on the upper end of the mounting column through a damping shaft. The control panel can input and execute machining data.

[0013] Preferably, a transverse feed box is fixedly installed on the upper end of the lathe base, and a longitudinal feed box is installed above the transverse feed box. A longitudinal moving seat is provided on the outer side of the longitudinal feed box, and a cutting tool holder is provided on the upper end of the longitudinal moving seat. A hydraulic cylinder is provided below the cutting tool holder. The height of the cutting tool can be adjusted by the hydraulic cylinder. At the same time, the transverse feed box can drive the longitudinal feed box to move laterally, and the longitudinal feed box can drive the longitudinal moving seat to move longitudinally.

[0014] The beneficial effects of this invention are: This invention transmits the feed motion of the longitudinal feed box to the wedge cover via a drive rack, incomplete gear, tie rod, and moving frame. The wedge cover's inclined surface and rollers then cooperate to convert the motion into synchronous radial clamping of multiple sector-shaped clamping blocks. This achieves a purely mechanical follow-up locking function where the tool is locked upon feed and released upon retraction. In this transmission chain, the tooth segment length of the incomplete gear corresponds to the clamping stroke, and the toothless segment corresponds to the stable cutting stroke. This ensures that the transmission chain automatically disengages after the clamping action is completed quickly in the initial stage of feed. This avoids wear and heat caused by prolonged gear and rack meshing and prevents slight fluctuations in feed from negatively impacting the stability of the clamping force. Simultaneously, the clamping force increases linearly with the feed stroke, adaptively matching the larger cutting resistance generated during roughing. This effectively compensates for the workpiece loosening defects caused by pressure fluctuations or leaks in traditional hydraulic or pneumatic clamping, significantly improving machining stability and the service life of the locking mechanism under heavy cutting conditions.

[0015] This invention achieves synchronous radial feed by using multiple ring-shaped sector clamps driven by the same wedge-shaped cover and inclined wheel frame. Combined with the rigid linkage structure of the movable rod and drive plate, and the precise guidance of the drive rack movement by the guide frame and guide post, it ensures that the displacement of each clamping surface relative to the rotation center line of the rotary cover is completely consistent. This allows the workpiece axis to be precisely locked at the rotation center of the rotary cover, providing an automatic centering function. Compared to traditional single-point clamping plates or independent jaws, this structure greatly reduces the end face perpendicularity error caused by clamping eccentricity, significantly improving the flatness and perpendicularity stability of the turned end face. Simultaneously, the rubber frame between the drive plate and the rotary cover acts as a buffer and vibration damper when clamped in place, avoiding rigid impact. Return springs evenly distributed on the outside of each movable rod ensure that each sector clamp returns to its original position consistently when the tool is unclamped, providing a highly consistent initial clamping state for batch processing and further improving dimensional consistency.

[0016] This invention, through the coordination of two clamping cylinders and a moving box with a lifting cylinder, enables parallel operations of finished product removal and blank placement at the same workstation. Combined with the automated output of the unloading conveyor belt, it significantly shortens the auxiliary time for loading and unloading, and substantially improves the production cycle time for batch processing. The entire locking, follow-up compensation, and loading / unloading connection process relies entirely on the geometric constraints and mechanical transmission of purely mechanical parts such as racks, gears, connecting rods, inclined planes, and springs. It eliminates the need for hydraulic stations, air pumps, solenoid valves, and associated sensors and electrical control systems. In automotive parts manufacturing workshops, where high reliability, ease of maintenance, and space utilization are crucial, it exhibits extremely high anti-interference capabilities and inherent reliability, with a very low failure rate. Routine maintenance only requires periodic lubrication of sliding surfaces and hinge points, significantly reducing the equipment's total lifecycle operating costs. Furthermore, the purely mechanical linkage method offers fast response and no lag, making it particularly suitable for mass production lines of automotive parts manufacturing. It can effectively improve the automation level and processing efficiency of the planetary gear shaft end face turning process in wheel-side reducers. Attached Figure Description

[0022] The synchronous automatic locking mechanism 4 also includes movable rods 42. Multiple movable rods 42, arranged in a straight line, are fixedly installed on the side of each sector-shaped clamping block 41 away from the center of the rotating cover 3. A drive plate 43 is fixedly installed at one end of each movable rod 42. An inclined wheel frame 46 is fixedly installed at the end of the drive plate 43 away from the sector-shaped clamping block 41. Rollers 47 are installed inside the highest and lowest points of the inclined plane of the inclined wheel frame 46 via bearings. The rollers 47 can drive the sector-shaped clamping block 41 along the movable rod 42. The axial sliding of the workpiece can improve the clamping accuracy. A rubber frame 45 is provided between the drive plate 43 and the rotary cover 3. A return spring 44 is provided on the outer side of each movable rod 42. One end of the return spring 44 is fixedly connected to the groove of the rotary cover 3, and the other end of the return spring 44 is fixedly connected to the drive plate 43. During the feeding process of the wedge cover 40, the drive plate 43 compresses the return spring 44. When the wedge cover 40 is reset, the return spring 44 can drive the drive plate 43 to return to the predetermined position through the elastic force.

[0023] Two guide rod frames 48 are fixedly installed on the upper end of the lathe base 1, symmetrically distributed around the rotary cover 3. The outer sides of the two guide rod frames 48 are slidably connected to a moving frame 49. A wedge-shaped cover 40 is installed inside the moving frame 49 through a bearing. The inner inclined surface of the wedge-shaped cover 40 contacts the roller 47. The wedge-shaped cover 40 can move along with the moving frame 49. During the movement, the contact between the inclined surface and the roller 47 can drive the roller 47 to move downward. At the same time, the wedge-shaped cover 40 can rotate along with the rotary cover 3.

An incomplete gear 55 is fixedly installed on the lower outer side of the rotating tube 53. The incomplete gear 55 meshes with the drive rack 51. During the movement, the drive rack 51 can drive the incomplete gear 55 to rotate by meshing with it. When it moves to the toothless position, the rotational force applied to the rotating tube 53 can be stopped, thus completing the movement of the moving frame 49.

[0025] A swing frame 54 is fixedly installed on the upper outer side of the rotating tube 53. A tie rod 57 is hinged inside the swing frame 54. A hinge frame 56 is fixedly installed on the lower front side of the moving frame 49. The tie rod 57 is hinged inside the hinge frame 56.

The guide post 59 is slidably connected inside the guide groove 50 on the back of the drive rack 51. The guide post 59 and the guide frame 58 can guide the movement of the drive rack 51.

[0026] The auxiliary loading and unloading mechanism 6 also includes a gantry frame 61. A movable box 62 is provided on the outer side of the adjustment end of the gantry frame 61. Two lifting cylinders 63 are fixedly installed on the inner side of the movable box 62. Each lifting cylinder 63 is equipped with a clamping cylinder 64 at its lower end. Two grippers are provided below the clamping cylinders 64. A loading conveyor belt 67 is provided in the middle of the upper end of the lathe base 1. A slant feed plate 65 is fixedly installed on the upper end of the lathe base 1. A drive mechanism is provided inside the frame of the loading conveyor belt 67. The workpiece after turning can be unloaded through the conveyor belt. While the two clamping cylinders 64 are placing the machined workpiece shaft, the other clamping cylinder 64 can simultaneously clamp the unmachined workpiece shaft.

[0027] The lathe base 1 has a spindle box 2 fixedly mounted on its upper end, a rotary cover 3 fixedly mounted on the outside of the rotating shaft of the spindle box 2, a mounting column 7 fixedly mounted on the upper right side of the lathe base 1, a control panel 8 mounted on the upper end of the mounting column 7 via a damping shaft, the control panel 8 can input and execute machining data, a transverse feed box 9 fixedly mounted on the upper end of the lathe base 1, a longitudinal feed box 10 mounted above the transverse feed box 9, a longitudinal moving seat 11 set on the outside of the longitudinal feed box 10, a cutting tool holder 12 set on the upper end of the longitudinal moving seat 11, a hydraulic cylinder set below the cutting tool holder 12, the height of the cutting tool can be adjusted by the hydraulic cylinder, and the longitudinal feed box 10 can be moved laterally by the transverse feed box 9, and the longitudinal feed box 10 can be moved longitudinally by the longitudinal moving seat 11.

[0028] The usage state of this invention is as follows: During processing, the auxiliary loading and unloading mechanism 6 is activated, and one of the two clamping cylinders 64 clamps the planetary gear shaft to be processed from the output end of the inclined groove feeding plate 65. Through the coordinated action of the lifting cylinder 63 and the moving box 62, the workpiece shaft is moved to the predetermined processing position inside the rotary cover 3. At this time, the fan-shaped clamping block 41 in the synchronous automatic locking mechanism 4 is in the open state under the elastic force of the return spring 44. The movable rod 42 and the drive plate 43 are located in the initial position away from the center of the rotary cover 3. There is a clamping gap between the outer circle of the workpiece shaft and the arc-shaped clamping groove of the fan-shaped clamping block 41, which facilitates the smooth placement of the workpiece. The cutting cycle is initiated. The transverse feed box 9 and the longitudinal feed box 10 drive the longitudinal moving seat 11 and the cutting tool holder 12 to feed towards the workpiece. The drive rack 51, fixedly mounted on the side of the longitudinal feed box 10, moves forward synchronously with the longitudinal feed box 10. The guide groove 50 on its back slides along the guide post 59 inside the guide frame 58 to ensure meshing accuracy. The drive rack 51 meshes with the incomplete gear 55 mounted on the rotating tube 53 outside the fixed shaft 52, causing the rotating tube 53 and the swing frame 54 to swing around the fixed shaft 52. The swing frame 54 pulls the moving frame 49 through the pull rod 57 and the hinge frame 56, causing the moving frame 49 to slide axially towards the rotary cover 3 along the guide rod frames 48 on both sides. The moving frame 49 drives the wedge cover 40 mounted inside it through the bearing to move axially synchronously. The inner inclined surface of the wedge cover 40 and the inclined wheel frame 46... The roller 47 contacts the wedge cover 40. As the wedge cover 40 advances, its inclined surface presses against the inclined wheel frame 46 through the roller 47, converting the axial movement of the wedge cover 40 into the radial inward movement of the inclined wheel frame 46. The inclined wheel frame 46 pulls multiple fan-shaped clamping blocks 41 arranged in a ring to move synchronously towards the center through the drive plate 43 and the movable rod 42, compressing the return spring 44, so that the arc-shaped clamping grooves of each fan-shaped clamping block 41 are evenly attached to the outer circle of the workpiece shaft, completing the centering and synchronous automatic locking of the workpiece. As the longitudinal feed box 10 continues to feed, the drive rack 51 continues to move forward. When the incomplete gear 55 rotates to the toothless section, the incomplete gear 55 disengages from the drive rack 51, the rotating tube 53 and the swing frame 54 stop swinging, and the axial position of the moving frame 49 and the wedge cover 40 is locked. At this time, the clamping force applied to the workpiece by the sector chuck 41 remains constant under the compression state of the return spring 44. The feed motion of the longitudinal feed box 10 does not stop, but the transverse feed box 9 and the longitudinal feed box 10 continue to drive the cutting tool to perform precision turning on the end face of the workpiece. During this process, the rubber frame 45 set between the drive plate 43 and the rotary cover 3 plays a buffering and vibration reduction role, preventing the cutting vibration from being transmitted to the clamping mechanism. Since the clamping action is triggered entirely by the feed stroke, and the clamping force is established and maintained in the early stage of feed, the follow-up effect of locking upon feed is achieved, effectively offsetting the cutting resistance generated in the roughing stage and preventing workpiece displacement. After the end face turning is completed, the longitudinal feed box 10 drives the drive rack 51 to move backward in the opposite direction, and the incomplete gear 55 rotates in the opposite direction. Through the rotating tube 53, the swing frame 54 and the pull rod 57, the moving frame 49 and the wedge cover 40 are pushed backward along the guide rod frame 48. The inclined surface of the wedge cover 40 disengages from the roller 47. Under the elastic force of multiple return springs 44, the drive plate 43 drives the fan-shaped clamping block 41 to open radially, releasing the workpiece. After the tool retraction is completed, the two clamping cylinders 64 in the auxiliary loading and unloading mechanism 6 move synchronously: one jaw clamps the finished workpiece shaft, and the other jaw simultaneously puts the next workpiece shaft to be processed from the output end of the inclined groove feed plate 65 into the rotary cover 3. The finished workpiece shaft is transferred to the unloading conveyor belt 67 and sent out. The unprocessed workpiece enters the preparatory position and waits for the next cycle to start, realizing seamless connection of loading and unloading processes and continuous batch processing, meeting the high cycle requirements of mass production of automotive parts.
