Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figures 1 to 10 As shown, the automatic wheelset bolt removal device of this utility model may include a movable adjustment mechanism 1 and a support base 2. The support base 2 is mounted on the movable adjustment mechanism 1, which is used to move and adjust the position of the support base 2. The support base 2 is provided with a turntable 3 and a drive mechanism 4. The turntable 3 is connected to the output end of the drive mechanism 4, which drives the turntable 3 to rotate around its own axis. Multiple tightening guns 5 are mounted on the turntable 3. The output end of each tightening gun 5 is connected to a sleeve 6, which drives the sleeve 6 to rotate to remove the bolts 201 at the end of the wheelset 20.

[0023] Specifically, the automatic disassembly device includes a movable adjustment mechanism 1 and a support base 2. The support base 2 is mounted on the movable adjustment mechanism 1, and its position can be adjusted via the movable adjustment mechanism 1 to accommodate the disassembly of bolts 201 on wheelsets 20 at different positions. The support base 2 is equipped with a turntable 3 and a drive mechanism 4. The drive mechanism 4 drives the turntable 3 to rotate around its axis. Multiple sets of tightening guns 5 are mounted on the turntable 3. The output end of each tightening gun 5 can be connected to a sleeve 6 of different specifications. The tightening gun 5 drives the sleeve 6 to rotate, thus facilitating the disassembly of bolts 201 of different specifications at the ends of the wheelsets 20. In this way, the drive mechanism 4 drives the turntable 3 to rotate, adjusting the sleeve 6 to correspond with the bolts 201 on the wheelsets 20, thereby enabling automatic disassembly of the bolts 201. This method is applicable to multiple specifications of bolts 201 on wheelsets 20, significantly improving disassembly efficiency and making it suitable for automated assembly line operations.

[0024] It should be noted that the automatic disassembly device has two moving adjustment mechanisms 1 and two support bases 2, with one moving adjustment mechanism 1 and one support base 2 corresponding to one end of the wheel pair 20. The tightening gun 5 is a conventional technology, and its specific structure will not be described in detail here.

[0025] In one example, such as Figure 3 and Figure 4 As shown, a rotating frame 7 is provided on the outer side of the support base 2. At least two sets of symmetrical clamping assemblies 8 are provided on the rotating frame 7. The clamping assembly 8 includes a clamping cylinder 801 and a clamping block 802. The telescopic end of the clamping cylinder 801 is connected to the clamping block 802. The clamping block 802 is used to press the outer side of the bearing 202 of the wheelset 20.

[0026] Specifically, the support base 2 has a rotating frame 7 on the side corresponding to the sleeve 6. At least two sets of symmetrical clamping components 8 are installed on the rotating frame 7 via a connecting plate 701. Each set of clamping components 8 includes a clamping cylinder 801 and a clamping block 802. The clamping cylinder 801 can push the clamping block 802 to move towards the bearing 202 of the wheelset 20. That is, after the sleeve 6 corresponds to the bolt 201 of the wheelset 20, the two clamping blocks 802 clamp the outer side of the bearing 202 of the wheelset 20 from both sides. This ensures the stability of the wheelset 20 during the process of starting the tightening gun 5 to drive the sleeve 6 to disassemble the bolt 201 of the wheelset 20, preventing displacement or rotation, and improving disassembly accuracy and safety.

[0027] In one example, such as Figures 3 to 5 As shown, the drive mechanism 4 includes a fixed base 401, a drive rod 402, and a drive motor 403. The fixed base 401 is disposed outside the support base 2, the drive motor 403 is disposed inside the fixed base 401, and the drive rod 402 is disposed at the center of the turntable 3. Both the output shaft of the drive motor 403 and the drive rod 402 are provided with pulleys 404, and a transmission belt 405 is provided between the two pulleys 404.

[0028] Specifically, the drive mechanism 4 includes a fixed base 401, a drive rod 402, and a drive motor 403. The fixed base 401 is set outside the support base 2, and the drive motor 403 is set inside the fixed base 401. The drive rod 402 is set at the center of the turntable 3. Both the output shaft of the drive motor 403 and the drive rod 402 are equipped with pulleys 404. A transmission belt 405 is set between the two pulleys 404, and power is transmitted through the transmission belt 405. This belt drive method has a simple structure, smooth transmission, and is easy to maintain and replace, making it suitable for high-frequency turntable 3 switching operations.

[0029] In one example, a connecting frame 406 is provided on the outside of the drive rod 402, and multiple connecting rods 407 are provided between the connecting frame 406 and the turntable 3. The multiple connecting rods 407 are evenly distributed along the circumference of the turntable 3.

[0030] Specifically, a connecting frame 406 is provided on the outside of the drive rod 402. Multiple connecting rods 407 are provided between the connecting frame 406 and the turntable 3. The connecting rods 407 are evenly distributed around the circumference of the turntable 3 to ensure a stable connection between the turntable 3 and the connecting frame 406. This enhances the rigidity and balance of the connection, prevents vibration or jamming caused by uneven load, and extends the service life of the equipment. In this way, the drive motor 403 drives the drive rod 402 to rotate through the transmission belt 405. The drive rod 402 drives the turntable 3 to rotate through the connecting frame 406 and the connecting rods 407, which facilitates the switching of the sleeve 6.

[0031] Furthermore, the connecting frame 406 may include a plurality of arc-shaped connecting plates evenly distributed circumferentially along the drive rod 402.

[0032] In one example, such as Figure 2 As shown, the movable adjustment mechanism 1 includes a mounting platform 101, a first base 102, and a second base 103. The first base 102 is equipped with a first slide rail 104 along a first direction, and the second base 103 is slidably mounted on the first slide rail 104. The second base 103 is equipped with a second slide rail 105 along a second direction, which is perpendicular to the first direction. The mounting platform 101 is slidably mounted on the second slide rail 105 and is used to mount the support base 2.

[0033] Specifically, the movable adjustment mechanism 1 includes a mounting platform 101, a first base 102, and a second base 103. The first base 102 is provided with a first slide rail 104 extending along a first direction. The second base 103 is slidably mounted on the first slide rail 104, allowing the second base 103 to be adjusted in position along the first direction. The second base 103 is provided with a second slide rail 105 extending along a second direction. The mounting platform 101 is slidably mounted on the second slide rail 105, allowing the mounting platform 101 to be adjusted in position along the second direction. The second direction is designed to be perpendicular to the first direction. This allows the movable adjustment mechanism 1 to enable precise movement of the support base 2 in two directions within the horizontal plane, facilitating the removal of bolts 201 from wheelsets 20 at different positions, thus improving the adaptability and flexibility of the device.

[0034] More specifically, the sliding of the mounting platform 101 on the second slide rail 105 and the sliding of the second base 103 on the first slide rail 104 can both be driven and adjusted by a motor in conjunction with a lead screw.

[0035] Furthermore, such as Figure 1 and Figure 2As shown, the automatic disassembly device also includes a sleeve replacement frame 9 correspondingly disposed on one side of the movable adjustment mechanism 1. The sleeve replacement frame 9 is used to replace the sleeve 6 at the output end of the tightening gun 5. The support base 2 can be moved and adjusted by the movable adjustment mechanism 1 to the corresponding position of the sleeve 6 and the sleeve replacement frame 9, so as to facilitate the replacement of the sleeve 6, thus enabling it to match and accommodate more bolt 201 specifications for wheelsets 20.

[0036] Furthermore, such as Figure 1 As shown, the automatic disassembly device also includes a robotic arm 10 located on one side of the moving adjustment mechanism 1, which can move and collect the disassembled bolts 201.

[0037] In one example, such as Figure 9 As shown, the automatic disassembly device also includes a fixed frame 11 and a wheelset support mechanism 12. The wheelset support mechanism 12 includes a telescopic cylinder 121, a support block 122, and a support roller 123. The telescopic cylinder 121 is vertically installed inside the fixed frame 11, with its telescopic end extending out of the top of the fixed frame 11 and connected to the support block 122. The support roller 123 is rotatably installed inside the support block 122 and is used to support the bearing 202 of the wheelset 20.

[0038] Specifically, a wheelset support mechanism 12 is provided on the fixed frame 11. The wheelset support mechanism 12 includes a support block 122, a support roller 123, and a telescopic cylinder 121. The telescopic cylinder 121 is vertically arranged inside the fixed frame 11. A telescopic rod is provided at the telescopic end of the telescopic cylinder 121, and a support block 122 is provided at the top of the telescopic rod. A rotatable support roller 123 is provided inside the support block 122. When the wheelset 20 slides along the two sets of tracks 19 to the processing position, the support roller 123 can support both ends of the bearing 202 of the wheelset 20. In this way, the support block 122 can be raised and lowered by controlling the telescopic cylinder 121, which can accommodate bearings 202 of different diameters of wheelset 20. The rolling of the support roller 123 can reduce friction, protect the surface of the bearing 202, and improve the adaptability of the device.

[0039] More specifically, the support block 122 can be V-shaped.

[0040] In one example, a vertical guide rod 124 is provided at the bottom of the support block 122, and a guide sleeve 125 is provided on the fixing frame 11. The guide rod 124 passes through the guide sleeve 125 and slides with it.

[0041] Specifically, the bottom of the support block 122 is provided with a guide rod 124, and the fixed frame 11 is provided with a guide sleeve 125. The guide rod 124 passes through the guide sleeve 125 and slides with it, which can prevent the support block 122 from shaking or tilting, so as to ensure that the support block 122 remains vertically stable during the lifting process and can extend the service life of the equipment.

[0042] In one example, such as Figures 6 to 8 As shown, the automatic disassembly device also includes a support frame 13 and a wheel hub fixing mechanism 14. The wheel hub fixing mechanism 14 includes two sets of auxiliary fixing components, both of which are mounted on the support frame 13 via fixing plates 141. The auxiliary fixing components are used to press against the inner side of the wheel hub of the wheelset 20 to position the axial position of the wheelset 20.

[0043] Specifically, a hub fixing mechanism 14 is provided on the support frame 13. The hub fixing mechanism 14 includes two sets of auxiliary fixing components, which are installed on the support frame 13 through fixing plates 141. These components are used to press against the inner side of the hub of the wheelset 20 from both axial sides of the wheelset 20 to restrict the axial movement of the wheelset 20. This effectively fixes the axial position of the wheelset 20, preventing axial movement during disassembly and ensuring the safety and stability of the disassembly process.

[0044] In one example, the auxiliary fixing assembly includes a first cylinder 142, a movable frame 143, and a pressure block 144. The telescopic end of the first cylinder 142 is connected to the movable frame 143, and the pressure block 144 is mounted on the movable frame 143 and is used to abut against the wheel hub of the wheelset 20.

[0045] Specifically, the auxiliary fixing assembly may include a first cylinder 142, a movable frame 143, and a pressure block 144. The first cylinder 142 is pressed onto the fixed plate 141, the movable frame 143 is mounted on the telescopic end of the first cylinder 142, and the pressure block 144 is mounted on the movable frame 143. The first cylinder 142 can push the movable frame 143 to move, causing the pressure block 144 to contact the inner side of the wheel hub of the wheelset 20 and apply pressure to restrict the axial movement of the wheelset 20. In this way, the first cylinder 142 drives the pressure block 144 to automatically clamp and release the wheel hub of the wheelset 20. The operation is simple and the response is fast, making it suitable for assembly line operations with frequent disassembly.

[0046] It should be noted that both sets of auxiliary fixing components of the wheel hub fixing mechanism 14 can both adopt the structure of the first cylinder 142, the movable frame 143, and the pressure block 144, or one set can adopt the structure of the first cylinder 142, the movable frame 143, and the pressure block 144, and the other set can adopt the structure of the auxiliary fixing frame 145 and the pressure block 144, as shown. Figures 6 to 8 As shown. The auxiliary fixing bracket 145 is mounted on the fixing plate 141, and the pressure block 144 is mounted on the auxiliary fixing bracket 145. When the first cylinder 142 on the other side drives the pressure block 144 to abut against the corresponding wheel hub of the wheel pair 20 and cannot move, the auxiliary fixing bracket 145 on this side also presses against the wheel hub of the wheel pair 20 on this side through the pressure block 144, thus achieving the corresponding function.

[0047] In one example, such as Figure 7As shown, a fixing block 15 is provided on the fixing frame 11, a second cylinder 16 is provided on the support frame 13, a movable plate 17 is provided on the piston rod of the second cylinder 16, and both the movable plate 17 and the fixing block 15 are provided with limiting blocks 18 for limiting the wheel hub.

[0048] Specifically, the fixed frame 11 is equipped with a fixed block 15, and the support frame 13 is equipped with a second cylinder 16. The piston rod of the second cylinder 16 is connected to a movable plate 17, and both the movable plate 17 and the fixed block 15 are equipped with limit blocks 18. When the wheelset 20 slides to the processing position, one side of the wheel hub abuts against the limit block 18 on the fixed block 15, and the second cylinder 16 drives the limit block 18 on the movable plate 17 to abut against the other side of the wheel hub, so as to restrict the position of the wheel hub from both sides, further ensuring the stability of the position of the wheelset 20 during the disassembly process and preventing displacement caused by external forces.

[0049] In one example, the automatic disassembly device also includes a camera and a control mechanism (not shown in the figures), the camera being used to identify the position of bolt 201, and the control mechanism being used to control the operation of the various actuators of the automatic disassembly device.

[0050] In summary, during operation, the automatic disassembly device can move the wheelset to the processing position via a track and limit it with a limiting block. The support block can support both ends of the wheelset bearing via support rollers. The pressure block can squeeze the wheelset hub to achieve axial fixation. The clamping block can clamp the wheelset bearing to achieve circumferential positioning. The position can be adjusted by the moving adjustment mechanism and the drive mechanism can drive the turntable to rotate. It can switch the sleeve according to different bolt specifications, which can meet the disassembly and use needs of multiple bolt specifications. The automatic disassembly device can also identify the bolt position through a camera. The tightening gun supports forward, backward and left and right movement and can realize automatic pitch change and automatic rotation to automatically disassemble various types of bolts. The robotic arm can move and collect the disassembled parts.

[0051] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
