Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, and provides a countersinking device. Background Technology

[0002] In the manufacturing process of railway vehicle bogies, the bogie frame, as a core load-bearing component, directly affects the overall vehicle's running performance and safety due to its machining accuracy. Among these components, the gearbox hanger is one of the key functional interfaces on the bogie frame, used to suspend the gearbox. The machining quality of its mounting holes directly affects the gearbox's assembly accuracy and operational stability. Countersinking is a crucial machining process for the gearbox hanger mounting holes, aiming to flatten the end faces of the mounting holes to ensure their flatness and perpendicularity, thus meeting subsequent assembly requirements.

[0003] Currently, when flattening the end faces of the mounting holes for gearbox hangers on a frame, the countersinking equipment used requires placing the frame on a support platform before performing the countersinking operation. This countersinking equipment requires a dedicated countersinking station, which occupies a large area and is usually far from the previous processing and inspection station (such as welding, rough machining, or inspection). It necessitates using overhead cranes or other lifting equipment to transfer the frame from the storage platform to the countersinking station, increasing transfer time, reducing efficiency, and increasing the frequency of crane use and operational risks.

[0004] Therefore, how to solve the problem of transferring the frame from the storage platform to the countersinking station when flattening the end face of the mounting hole of the gearbox hanger on the frame has become an important technical problem for those skilled in the art.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] The following is combined with Figures 1 to 6 This invention describes the countersinking equipment.

[0027] like Figures 1 to 6As shown, the countersinking device provided in this embodiment of the present invention includes a traveling trolley 1, a vertical drive device 2, a countersinking device, and a clamping device.

[0028] Specifically, the vertical drive device 2 is mounted on the traveling trolley 1. When the traveling trolley 1 is on the ground, it can drive the vertical drive device 2 to move along the ground. The vertical drive device 2 has a vertical moving part that can reciprocate vertically along the traveling trolley 1. When the traveling trolley 1 is on a horizontal surface, its vertical direction is vertical. The vertical direction of the traveling trolley is as follows: Figure 1 The direction indicated by z in the middle.

[0029] The countersinking device includes a countersinking device body 3 and a processing tool. The countersinking device body 3 is located on the vertical moving part. The countersinking device can move along the ground with the traveling trolley 1 together with the vertical drive device 2. The countersinking device can also move vertically along the traveling trolley 1 with the vertical moving part, thereby adjusting the height of the countersinking device.

[0030] The countersinking device body 3 is used to drive the machining tool to rotate around a reference axis and to move the machining tool along the reference axis. The reference axis is parallel to the vertical direction of the traveling carriage 1. The reference axis is as follows: Figure 1 The straight line indicated by m. The machining tool is located on the side of the countersinking device body 3 away from the traveling carriage 1. When the traveling carriage 1 is on the ground, the machining tool is located above the countersinking device body 3, and the countersinking device can perform countersinking treatment below the target workpiece.

[0031] The clamping device is installed on the main body 3 of the countersinking device. The clamping device is used to clamp the target workpiece to ensure the relative fixation between the main body 3 of the countersinking device and the target workpiece, so as to ensure the countersinking accuracy.

[0032] The frame located at the storage platform is suspended in the air, and the gearbox hanger is fixed below the frame. The traveling trolley 1 can move along the ground where the storage platform is located, and can also move the countersinking device body 3 to below the frame located at the storage platform.

[0033] The gearbox hanger is the target workpiece. The trolley 1 moves on the ground to adjust the position of the countersinking device body 3, aligning the rotation axis of the machining tool with the axis of the mounting hole of the gearbox hanger. The gearbox hanger is then clamped using a clamping device, fixing the countersinking device body 3 relative to it. The machining tool of the countersinking device is then positioned on the upper surface of the mounting hole of the gearbox hanger, and the movement of the countersinking device body 3 is controlled to countersink the upper surface of the mounting hole of the gearbox hanger.

[0034] With this configuration, the countersinking equipment provided in this embodiment of the present invention can directly countersink the gearbox hanger of the frame located on the storage platform without the need for an additional support platform or the need to transport the frame. This solves the problem in related technologies where the frame needs to be transported from the storage platform to the countersinking station when flattening the end face of the mounting hole of the gearbox hanger on the frame.

[0035] The aforementioned vertical drive device 2 includes a vertical support, a sliding support, and a vertical drive mechanism.

[0036] A vertical support is fixedly mounted on the load-bearing part of the traveling trolley 1, and the axis of the vertical support is along the vertical direction of the traveling trolley 1. A sliding support is slidably connected to the vertical support, and the sliding direction of the sliding support relative to the vertical support is along the axis of the vertical support. The sliding support serves as the aforementioned vertical moving part. A vertical drive mechanism is disposed between the vertical support and the sliding support, and is used to drive the sliding support to reciprocate relative to the vertical support.

[0037] The vertical drive mechanism may, but is not limited to, a lead screw and nut transmission mechanism driven by a motor.

[0038] In this embodiment of the utility model, the clamping device includes a clamping member 6, a pair of mounting seats 4, and a pair of clamping blocks 5.

[0039] A pair of mounting seats 4 are fixedly mounted on the countersinking device body 3 near the end of the machining tool, and the pair of mounting seats 4 are located on opposite sides of the countersinking device body 3. A pair of clamping blocks 5 correspond one-to-one with the pair of mounting seats 4, with each mounting seat 4 corresponding to one clamping block 5. The clamping blocks 5 are rotatably mounted on the mounting seats 4, and the rotation axes of the pair of clamping blocks 5 relative to the mounting seats 4 are parallel and perpendicular to the reference axis.

[0040] Reference Figures 2 to 4 The first end of the clamping block 5 is rotatably connected to the mounting base 4. When the pair of clamping blocks 5 rotate relative to the mounting base 4, the second ends of the pair of clamping blocks 5 move closer to or further away from each other. When the second ends of the pair of clamping blocks 5 move closer to each other to a certain extent, the second ends of the pair of clamping blocks 5 clamp the target workpiece.

[0041] The clamping element 6 is mounted on the mounting base 4. The axis of the clamping element 6 is angled to the reference axis. One end of the clamping element 6 abuts against the side of the clamping block 5 away from the countersinking device body 3. The position of the clamping element 6 on the mounting base 4 is adjustable along its axis. By adjusting the position of the clamping element 6 on the mounting base 4, the rotational position of the clamping block 5 relative to the mounting base 4 can be adjusted, thereby adjusting the clamping force of the pair of clamping blocks 5 on the target workpiece.

[0042] In a specific embodiment, the clamping member 6 is threadedly connected to the mounting base 4. By rotating the clamping member 6, the relative position of the clamping member 6 and the mounting base 4 can be adjusted along the axial direction of the clamping member 6. Under the action of thread self-locking, when the rotation of the clamping member 6 is stopped, the clamping member 6 and the mounting base 4 remain relatively stationary, which allows the clamping device to maintain the clamping force on the target workpiece.

[0043] In this embodiment, the mounting base 4 includes a fixed base 7, a rotating base 8, and a locking element.

[0044] The fixed base 7 is fixedly connected to the main body 3 of the countersinking device, and the clamping block 5 is rotatably connected to the fixed base 7. The rotating base 8 is rotatably connected to the fixed base 7, and the rotation axis of the rotating base 8 relative to the fixed base 7 is parallel to the rotation axis of the clamping block 5 relative to the fixed base 7. The abutting member 6 is threadedly connected to the rotating base 8. By rotating the rotating base 8 relative to the fixed base 7, the axial direction of the abutting member 6 can be adjusted, thereby adjusting the direction of the abutting force of the abutting member 6 on the clamping block 5.

[0045] Based on the angle of the clamping block 5 when clamping the target workpiece, adjust the axial direction of the abutment 6 to make the axis of the abutment 6 as perpendicular as possible to the side surface of the clamping block 5 away from the target workpiece, optimize the force on the abutment 6 and the clamping block 5, ensure the clamping force of the abutment 6 on the clamping block 5, and ensure the stability of the clamping block 5.

[0046] The locking element can selectively lock the rotating seat 8 to the fixed seat 7. After adjusting the axial direction of the abutment 6, the rotating seat 8 and the fixed seat 7 are locked together by the locking element to ensure the stability of the abutment 6 and the reliability of the clamping device.

[0047] Specifically, the locking element includes a locking bolt. A connecting hole is provided on the fixed seat 7, and a threaded hole is provided on the rotating seat 8. The locking bolt passes through the connecting hole of the fixed seat 7 and is threadedly connected to the threaded hole on the rotating seat 8. Loosening the locking bolt allows the rotating seat 8 to rotate relative to the fixed seat 7, adjusting the angle of the abutment 6. Tightening the locking bolt fixes the rotating seat 8 relative to the fixed seat 7, ensuring the stability of the abutment 6.

[0048] A screwing part is provided at the end of the clamping member 6 away from the main body 3 of the countersinking device. The operator can apply torque to the clamping member 6 through the screwing part so that the clamping member 6 rotates relative to the rotating seat 8, which is convenient and labor-saving.

[0049] In this embodiment of the utility model, the main body 3 of the countersinking device includes a shell 9, a main shaft 10, a rotation drive module and a movement drive module.

[0050] The outer shell 9 serves as a support and protection for the main body 3 of the countersinking device, and it is fixedly connected to the vertical moving part.

[0051] The spindle 10 is disposed inside the housing 9, and its axis serves as a reference axis, aligning with the vertical direction of the traveling carriage 1. The spindle 10 is capable of rotating relative to the housing 9 about its own axis, and also capable of moving relative to the housing 9 along its own axis. A first end of the spindle 10 extends to the outside of the housing 9, and the machining tool is detachably connected to the first end of the spindle 10. When the spindle 10 rotates and moves relative to the housing 9, it drives the machining tool to rotate and move relative to the housing 9.

[0052] The rotation drive module drives the spindle 10 to rotate relative to the housing 9, and the motion drive module drives the spindle 10 to move relative to the housing 9. Simultaneously, the spindle 10 can move relative to the output end of the rotation drive module along its own axis, ensuring that the rotation drive module does not interfere with the spindle 10's movement when driving it to rotate. Similarly, the spindle 10 can rotate about its own axis relative to the output end of the motion drive module, ensuring that the motion drive module does not interfere with the spindle 10's rotation when driving it to move.

[0053] In the specific working process, after adjusting the position of the countersinking device body 3 and clamping the gearbox hanger with the clamping device, the machining tool is removed from the first end of the spindle 10. The moving drive module drives the spindle 10 to move upward until the first end of the spindle 10 extends out from above the gearbox hanger. The machining tool is fixed to the first end of the spindle 10, with the cutting edge of the machining tool facing the upper end face of the mounting hole of the gearbox hanger. Then, the rotation drive module drives the spindle 10 to rotate for countersinking. After the countersinking is completed, the machining tool is removed from the first end of the spindle 10, and the moving drive module drives the spindle 10 to move downward. Finally, the clamping device releases the gearbox hanger.

[0054] The end of the outer casing 9 is provided with a through hole for the first end of the main shaft 10 to pass through. A raised edge is provided around the periphery of the through hole. The raised edge is located outside the outer casing 9. The outer side wall contour of the raised edge is consistent with the inner side wall contour of the mounting hole of the gearbox hanger, and the raised edge is coaxial with the main shaft 10. When adjusting the position of the countersinking device body 3, the raised edge can be inserted into the mounting hole of the gearbox hanger. The outer side wall of the raised edge interacts with the side wall of the mounting hole of the gearbox hanger to achieve positioning.

[0055] In this embodiment, the rotation drive module includes a first support bushing 11, a first transmission mechanism 12, and a first drive component 13, such as... Figure 6 As shown.

[0056] The first support bushing 11 is disposed outside the outer shell 9 and is coaxially disposed with the main shaft 10. The first support bushing 11 is rotatably connected to the outer shell 9. The first support bushing 11 and the main shaft 10 can only move relative to each other along the axis of the main shaft 10. The first support bushing 11 and the main shaft 10 cannot rotate relative to each other.

[0057] The first transmission mechanism 12 has a driving member and a driven member that can rotate on a fixed axis. The driven member of the first transmission mechanism 12 is coaxially fixed with the first support bushing 11. The driven member of the first transmission mechanism 12 can drive the first support bushing 11 to rotate synchronously, thereby driving the main shaft 10 to rotate.

[0058] The output end of the first driving member 13 is connected to the driving member of the first transmission mechanism 12 for driving the driving member of the first transmission mechanism 12 to rotate relative to the housing 9. The rotational torque output by the first driving member 13 is transmitted to the first support bushing 11 through the first transmission mechanism 12, causing the first support bushing 11 to rotate relative to the housing 9, thereby driving the main shaft 10 to rotate relative to the housing 9.

[0059] Specifically, the first transmission mechanism 12 may be configured as a gear transmission mechanism or a worm gear transmission mechanism, but is not limited to such a configuration.

[0060] When the first transmission mechanism 12 is configured as a gear transmission mechanism, both the driving and driven components of the first transmission mechanism 12 are configured as bevel gears. In this case, the axis of the driving component of the first transmission assembly is perpendicular to the axis of the main shaft 10, which reduces the axial space occupied by the countersinking device body 3, facilitates the arrangement of the moving drive module, and makes the countersinking device structurally compact and optimized in layout.

[0061] The first driving component 13 mentioned above may be, but is not limited to, a motor.

[0062] In a specific embodiment, for the mating structure between the first support sleeve 11 and the main shaft 10, an internal spline can be provided on the inner sidewall of the first support sleeve 11, and an external spline can be provided on the outer sidewall of the main shaft 10. The internal spline and the external spline are adapted to each other and can transmit torque along the circumference of the main shaft 10, so that the first support sleeve 11 drives the main shaft 10 to rotate. The internal spline and the external spline slide along the axial direction of the main shaft 10, thereby allowing the main shaft 10 to move relative to the first support sleeve 11.

[0063] In this embodiment, the moving drive module includes a second support bushing 14 and a drive mechanism.

[0064] like Figure 6 As shown, the second support bushing 14 is disposed inside the housing 9 and can only reciprocate along the axial direction of the main shaft 10. The second support bushing 14 cannot rotate relative to the housing 9. The second support bushing 14 is coaxially arranged and rotatably engaged with the main shaft 10, and the second support bushing 14 does not affect the rotation of the main shaft 10. The relative position of the second support bushing 14 and the main shaft 10 along the axial direction of the main shaft 10 is fixed. When the second support bushing 14 moves relative to the housing 9, it can drive the main shaft 10 to move.

[0065] The drive mechanism is used to drive the second support bushing 14 to move relative to the housing 9.

[0066] In some embodiments, the drive mechanism can be configured as a rack and pinion mechanism, a lead screw and nut mechanism, a cylinder, a hydraulic cylinder, etc.

[0067] In another embodiment, the drive mechanism includes a third support bushing 15, a transmission assembly, and a second drive member 16.

[0068] Reference Figure 6 The third support bushing 15 is sleeved outside the second support bushing 14. The third support bushing 15 can only rotate relative to the outer shell 9, and the third support bushing 15 and the outer shell 9 cannot move relative to each other. The third support bushing 15 and the second support bushing 14 are connected by a thread, and when the third support bushing 15 rotates relative to the outer shell 9, the second support bushing 14 can move relative to the outer shell 9.

[0069] The transmission assembly has a driving member and a driven member that can rotate around a fixed axis. The driven member of the transmission assembly is coaxially fixed with the third support bushing 15. The driven member of the transmission assembly can drive the third support bushing 15 to rotate synchronously, thereby causing the second support bushing 14 to move relative to the outer shell 9.

[0070] The output end of the second driving member 16 is connected to the driving member of the transmission assembly, and is used to drive the driving member of the transmission assembly to rotate relative to the housing 9. The rotational torque output by the second driving member 16 is transmitted to the second support bushing 14 through the transmission assembly and the third support bushing 15, causing the second support bushing 14 to move relative to the housing 9, thereby driving the main shaft 10 to move relative to the housing 9.

[0071] Specifically, the aforementioned transmission assembly can be a worm gear transmission assembly. In the worm gear transmission assembly, the worm wheel 19 is the driven member, and its axis coincides with the axis of the main shaft 10. The worm in the worm gear transmission assembly is the driving member, and its axis is perpendicular to the axis of the main shaft 10. The worm gear transmission assembly reduces the axial space occupied by the countersinking device body 3, facilitates the arrangement of the rotation drive module, and makes the countersinking device structurally compact and its layout optimized.

[0072] The second drive component 16 mentioned above may be, but is not limited to, a motor.

[0073] In this embodiment of the utility model, the main body 3 of the countersinking device also includes a movement distance detection module, which is disposed between the outer shell 9 and the main shaft 10 and is used to detect the movement distance of the main shaft 10 relative to the outer shell 9.

[0074] In this way, the countersinking depth of the countersinking device can be precisely monitored, so that the operator or control system can accurately judge the processing progress. This not only effectively prevents the scrapping of workpieces due to excessive or insufficient processing depth, but also significantly improves the accuracy, efficiency and consistency of countersinking operations, meeting the high standards of modern precision machining.

[0075] In this embodiment, the movement distance detection module includes a scale 17 and a reading head 18.

[0076] The scale 17 is located outside the housing 9. The scale 17 can only reciprocate along the axis of the main shaft 10; the scale 17 and the housing 9 cannot rotate relative to each other. The scale 17 is connected to the second end of the main shaft 10 via a connecting bracket, and the scale 17 and the connecting bracket are fixed relative to each other. The connecting bracket cannot move relative to the main shaft 10; the connecting bracket moves synchronously with the main shaft 10. The connecting bracket can rotate relative to the main shaft 10, but it cannot rotate synchronously with the main shaft 10.

[0077] When the spindle 10 moves relative to the housing 9, the scale 17 can be moved relative to the housing 9 through the connecting bracket, that is, the scale 17 and the spindle 10 move synchronously.

[0078] The reading head 18 is fixedly mounted on the housing 9. The scale 17 has spaced graduations. When the scale 17 moves relative to the housing 9, different graduations on the scale 17 pass through the reading head 18. The reading head 18 can read these different graduations to convert the mechanical displacement of the spindle 10 into a precise digital signal. This not only completely eliminates subjective errors caused by manual observation and estimation, but also significantly improves reading efficiency and reliability.
