Technical Field

[0001] This utility model relates to the field of processing equipment, and provides a processing device for anti-roll torsion bars. Background Technology

[0002] To ensure smooth operation and improve efficiency in the production process of high-speed trains, different equipment is used for the pressing, unloading, and pressure testing of anti-roll torsion bars during routine new manufacturing and maintenance. The pressing and unloading processes are typically performed using a semi-automated operation mode, where the equipment is operated manually to complete the specific steps.

[0003] When operating in stages at both ends, the position of the torsion bar is usually adjusted by using an overhead crane. The main problems with this method are: firstly, the decentralized operation and frequent adjustments increase the process flow time and extend the time for each individual operation; secondly, the use of multiple devices leads to wasted space and complex process layout; and finally, although the semi-automatic operation method saves some manpower, the quality of operation is difficult to guarantee, and there is a certain degree of uncertainty and error.

[0009] According to one embodiment of the present invention, the lifting mechanism is located at the center of gravity of the anti-roll torsion bar and is capable of rotating the anti-roll torsion bar by 180 degrees.

[0010] According to one embodiment of the present invention, the actuating pressure head has a split structure, the actuating pressure head includes a central pressure part and a peripheral pressure part, and the central pressure part can move axially relative to the peripheral pressure part.

[0012] According to one embodiment of the present invention, the anti-roll bar mechanism includes a first movable base member that can move axially along the anti-roll bar to achieve axial limiting of the anti-roll bar.

[0013] According to one embodiment of the present invention, the stop arm mechanism includes a second movable base member that can move vertically to limit the torsion bar arm of the anti-roll torsion bar.

[0014] According to one embodiment of the present invention, the actuating pressure head is driven by a hydraulic cylinder.

[0015] According to one embodiment of the present invention, it further includes:

Integrating the required execution pressure head and lifting mechanism onto the same basic structure eliminates the need for multiple dedicated devices to complete the processing at both ends separately, greatly simplifying the production process layout, reducing the overall equipment footprint, and lowering the investment costs for equipment procurement and production site. The lifting mechanism automatically completes the raising, rotating, and lowering of the anti-roll torsion bar, eliminating the need for manual flipping and hoisting of the workpiece.

[0032] like Figures 1 to 3 As shown, this utility model embodiment provides a processing device for anti-roll torsion bars, comprising:

[0033] Infrastructure 100;

[0034] An actuating pressure head 102, mounted on the base structure 100, is used to apply force to one end of the anti-roll torsion bar;

[0035] A lifting mechanism 104 is mounted on the base structure 100. The lifting mechanism 104 is adapted to lift and rotate the anti-roll torsion bar to process the two ends of the anti-roll torsion bar.

[0036] According to the processing device for anti-roll torsion bars provided in this embodiment of the utility model, the lifting and rotation functions of the lifting mechanism 104 allow for the processing of both ends of the anti-roll torsion bar to be completed on the same device. This eliminates the need for overhead cranes to transport and transfer workpieces or change processing stations, saving time spent on multiple processes, significantly shortening the processing time for a single workpiece, and greatly improving the processing efficiency of the anti-roll torsion bar. Both the execution pressure head 102 and the lifting mechanism 104 are installed on the same basic structure 100, sharing a unified installation and positioning reference, avoiding reference deviations caused by multi-station and multi-equipment processing. The precise rotational positioning of the lifting mechanism 104 ensures that the relative position accuracy between the two ends of the anti-roll torsion bar and the execution pressure head 102 is consistent after switching, effectively guaranteeing the uniformity and stability of the processing accuracy at both ends of the torsion bar. Integrating the execution pressure head 102 and the lifting mechanism 104 required for processing onto the same basic structure 100 eliminates the need for multiple dedicated devices to complete the processing at both ends separately, greatly simplifying the production process layout, reducing the overall footprint of the equipment, and lowering the investment costs for equipment procurement and production site. The lifting mechanism 104 automatically completes the lifting, rotation, and lowering of the anti-roll torsion bar, eliminating the need for manual flipping and hoisting of the workpiece. This significantly reduces the labor intensity of operators and avoids safety risks such as workpiece falling and collisions that may occur during manual hoisting, thus improving the safety of the operation. Through the standardized lifting and rotation switching function of the lifting mechanism 104, it can adapt to the processing requirements of both ends of anti-roll torsion bars of different lengths without requiring adjustments to the main structure of the device. This enhances the versatility and adaptability of the device and can meet the batch processing needs of anti-roll torsion bars.

[0037] Please continue to participate. Figures 1 to 3 The processing device for anti-roll torsion bar provided in this embodiment of the utility model achieves continuous integrated processing of both ends of the anti-roll torsion bar through the coordinated cooperation of the basic structure 100, the execution pressure head 102 and the lifting mechanism 104.

[0038] The basic structure 100 is the core load-bearing base of the entire processing device. It adopts a horizontal frame structure, is made of high-strength steel through overall processing and aging treatment, and has a reasonable reinforcement layout, possessing excellent rigidity and deformation resistance, and can stably withstand various loads during processing without deformation. The basic structure 100 is equipped with precise positioning benchmarks and standardized installation interfaces for the fixed installation of the pressure head 102 and the lifting mechanism 104, ensuring that the relative positional accuracy between the components meets the processing requirements. The bottom of the basic structure 100 has a fixing structure, which can be firmly installed on the foundation of the work site with fasteners and leveled, providing a stable foundation for the overall operation of the device.

[0039] The pressure head 102 is fixedly installed in the end area of ​​the base structure 100. Its force-applying end is precisely aligned with the axial direction of the anti-roll torsion bar, and it can output a stable linear force along the axial direction of the anti-roll torsion bar, which directly acts on the end of the anti-roll torsion bar to be processed, providing a stable power output for the processing procedures such as pressing, unloading, and pressure testing of the anti-roll torsion bar.

[0040] The lifting mechanism 104 is fixedly installed in the middle area of ​​the foundation 100, directly below the anti-roll torsion bar placement position, and has dual-degree-of-freedom movement capabilities of lifting and rotation. The lifting mechanism 104 can smoothly lift the anti-roll torsion bar placed on the device upwards, causing the anti-roll torsion bar to leave its initial placement state; then drive the anti-roll torsion bar to rotate around its own axis, completing the position switching of the two ends of the anti-roll torsion bar; after the switching is completed, the lifting mechanism 104 drives the anti-roll torsion bar to smoothly fall back to its original position, so that the other end of the anti-roll torsion bar is aligned with the force-applying end of the actuator 102, thereby completing continuous processing of both ends of the anti-roll torsion bar on the same device.

[0041] According to one embodiment of the present invention, the lifting mechanism 104 is located at the center of gravity of the anti-roll torsion bar and is capable of rotating the anti-roll torsion bar by 180 degrees.

[0042] In one embodiment of this utility model, the lifting mechanism 104 adopts a dual-cylinder drive structure and is arranged in the center of gravity area of ​​the anti-roll torsion bar. The lifting stroke can completely lift the anti-roll torsion bar and separate it from the lower support 114. The lifting mechanism 104 has a built-in rotary drive component, which can drive the anti-roll torsion bar to rotate smoothly 180 degrees around its own axis, so that the two ends of the anti-roll torsion bar can be switched to the working position of the execution pressure head 102 in sequence, so as to realize the sequential processing of the two ends.

[0043] By positioning the lifting mechanism 104 at the center of gravity, the anti-roll torsion bar can be ensured to have balanced force and stable posture during lifting and rotation, avoiding uneven loading, swaying or deformation. The pressing, unloading and pressure testing of both ends of the anti-roll torsion bar can be completed on the same equipment without the need for overhead crane hoisting or changing work positions, which greatly shortens the process flow time and improves work efficiency. The 180-degree rotation is reliable and the positioning is accurate, ensuring consistent processing accuracy at both ends and improving the stability of work quality.

[0044] According to one embodiment of the present invention, the execution pressure head 102 has a split structure, and the execution pressure head 102 includes a central pressure part 106 and a peripheral pressure part 108. The central pressure part 106 can move relative to the peripheral pressure part 108 in the axial direction of the peripheral pressure part 108.

[0045] In one embodiment of this utility model, the actuating pressure head 102 achieves circumferential relative fixation and axial relative movement through a wedge-shaped groove key fit structure; the axial movement of the central pressure part 106 is greater than the distance from the end of the torsion bar shaft to the near end face of the torsion bar arm, and the inner diameter of the outer pressure part 108 is greater than the diameter of the torsion bar shaft, so that the actuating pressure head 102 can switch the extension state according to different operation modes such as pressing, unloading, and pressure testing, and act on the end face of the torsion bar arm or the torsion bar shaft respectively.

[0046] The split structure allows the same pressure head 102 to be adapted to three operating modes: pressing, unloading, and pressure testing, without the need to change tooling, achieving multi-purpose functionality. For example, during the pressing process, the axially movable design of the central pressure part 106 and the outer pressure part 108 can apply force to the torsion bar arm and torsion bar shaft respectively. That is, the torsion bar shaft can be positioned by first applying axial force to the torsion bar shaft through the central pressure part 106. After the torsion bar shaft is positioned, the torsion bar arm is installed to the end of the torsion bar shaft, and then the torsion bar arm is positioned by the central pressure part 106. This design ensures accurate positioning and reasonable force distribution between the torsion bar shafts, avoiding damage to the workpiece. The wedge-shaped groove key fit ensures no circumferential movement and smooth axial movement, resulting in reliable operation and a long service life.

[0047] According to one embodiment of the present invention, it further includes a shaft-stopping mechanism 110 and a arm-stopping mechanism 112, which are used to position the anti-roll torsion bar during the processing.

[0048] In one embodiment of this utility model, the shaft-stopping mechanism 110 is used to axially limit the torsion bar shaft of the anti-rolling torsion bar, and the arm-stopping mechanism 112 is used to limit the torsion bar arm of the anti-rolling torsion bar. During pressing, unloading, and pressure testing operations, the shaft-stopping mechanism 110 and the arm-stopping mechanism 112 operate according to the operation mode, forming a counterforce with the pressure head 102 to ensure that the anti-rolling torsion bar does not move, rotate, or shift during processing.

[0049] The coordinated positioning of the anti-roll torsion bar 110 and the anti-arm mechanism 112 ensures that the anti-roll torsion bar maintains a stable posture during machining under stress, avoiding displacement and deflection that could lead to insufficient machining accuracy. Reliable positioning ensures that the pressing force, unloading force, and inspection force are applied accurately, improving work consistency and pass rate. The dual-mechanism positioning adapts to various operating modes, enhancing the versatility and stability of the device.

[0050] According to one embodiment of the present invention, the anti-roll torsion bar mechanism 110 includes a first movable base member that can move axially along the anti-roll torsion bar to achieve axial limiting of the anti-roll torsion bar.

[0051] In one embodiment of this utility model, the shaft-stopping mechanism 110 consists of a fixed base, a sliding assembly, and a first movable base. The sliding assembly is a wheel-rail sliding structure, and the first movable base is a limiting rod that can extend or retract along the axial direction of the anti-roll torsion bar. During the pressing operation, the first movable base extends and presses against the end face of the torsion bar shaft. During the unloading and pressure testing operations, the first movable base retracts to avoid collision, thereby achieving controllable switching of axial limiting.

[0052] The axially movable limiting structure can automatically switch the limiting state according to different operating modes without manual adjustment, resulting in a high degree of automation; the wheel-rail sliding fit ensures smooth movement, low resistance, and accurate positioning, guaranteeing reliable and stable axial limiting; it can be adapted to anti-roll torsion bars of different lengths, enhancing the versatility and adaptability of the device.

[0053] According to one embodiment of the present invention, the stop arm mechanism 112 includes a second movable base member that can move vertically to limit the torsion arm that counteracts the side roll torsion bar.

[0054] In one embodiment of this utility model, the stop arm mechanism 112 consists of a fixed base, a sliding component and a second moving base. The sliding component is a wheel-rail sliding structure, and the second moving base is a limiting block that can be raised and lowered vertically. During unloading and pressure testing operations, the second moving base rises to press against the inner side of the torsion bar arm, and during pressing operations, the second moving base descends to avoid it, thereby achieving reliable limiting of the torsion bar arm.

[0055] The vertical lifting limit block can automatically switch according to the operation mode, forming a reverse constraint with the execution pressure head 102 to ensure that the torsion bar arm does not move during unloading and pressure testing; the sliding cooperation ensures smooth lifting without jamming, reliable limit, and improved processing accuracy and operation stability; the simple structure and fast action response improve the efficiency of automated operation.

[0056] According to one embodiment of the present invention, the pressure head 102 is driven by a hydraulic cylinder.

[0057] In one embodiment of this utility model, the hydraulic cylinder is a precision-machined hydraulic cylinder, which is fixedly installed on the base structure 100. The piston rod of the hydraulic cylinder is connected to the actuator head 102 through transmission. The piston rod is driven to extend and retract by hydraulic oil, providing the actuator head 102 with the axial force required for pressing, unloading, and pressure testing. The thrust is stable and the stroke is controllable.

[0058] The hydraulic cylinder drive has high output, smooth operation, and adjustable pressure, which can meet the needs of large-tonnage pressing and unloading of anti-roll torsion bars; the hydraulic transmission has fast response and low impact, which can avoid instantaneous impact damage to the workpiece; the thrust and stroke are controllable, improving the stability and accuracy of the processing.

[0059] According to one embodiment of the present invention, it further includes:

[0060] Control system; The control system is used to control the movement of the hydraulic cylinder.

[0061] The sensing module is used to detect pressure and displacement information and feed it back to the control system to achieve closed-loop control.

[0062] In one embodiment of this utility model, the control system is based on a PLC and a servo controller. The sensing module includes a high-precision pressure sensor and a displacement sensor. The pressure sensor detects the force of the actuator head 102 in real time, and the displacement sensor detects the relative displacement between the actuator head 102 and the torsion bar in real time. The detection signals are fed back to the control system in real time. The control system automatically adjusts the pressure, speed and stroke of the hydraulic cylinder according to the set parameters to form a closed-loop control.

[0063] Closed-loop control enables precise adjustment and real-time monitoring of pressure and displacement, ensuring that the pressing force, inspection pressure, and unloading stroke are accurately met; it automatically corrects deviations, improves operational accuracy and consistency, and reduces human error; it can automatically determine whether the work is qualified or not, improving operational quality and reliability, and meeting the high-precision requirements of EMU components.

[0064] According to one embodiment of the present invention, it further includes at least one support base 114, on which a clamp for clamping the anti-roll torsion bar is provided.

[0065] In one embodiment of the present invention, the support base 114 is arranged on the base structure 100 to support the anti-roll torsion bar; the clamp on the support base 114 is a clamping mechanism that can automatically hold the rod body of the anti-roll torsion bar and firmly fix the anti-roll torsion bar when the lifting mechanism 104 is not lifting, so as to prevent shaking, rotation or displacement during processing.

[0066] The support base 114 and the fixture together ensure that the anti-roll torsion bar is stable in posture and accurately positioned during processing, thus improving processing accuracy; the clamping action is reliable and can be adapted to torsion bar shafts of different diameters, making it highly versatile; in conjunction with the lifting mechanism 104, the lifting and rotation realizes the automated process of clamping, lifting, rotating, and clamping, improving work efficiency.

[0067] According to one embodiment of the present invention, the basic structure 100 is a horizontal frame structure, and the pressure head 102 and the lifting mechanism 104 are both arranged on the horizontal frame structure.

[0068] In one embodiment of this utility model, the basic structure 100 is made of 45# steel and welded as a whole and subjected to aging treatment. It is a horizontal double-bar frame main structure with strong overall rigidity and no deformation. The execution pressure head 102, hydraulic cylinder, shaft stop mechanism 110, arm stop mechanism 112, support seat 114, and lifting mechanism 104 are all integrated and installed on the same horizontal frame to form an integrated processing platform.

[0069] The horizontal frame structure has high rigidity and good stability, and can withstand heavy tonnage processing loads without deformation, ensuring long-term accuracy. All mechanisms are integrated into the same frame, resulting in a compact structure, small footprint, and simplified process layout. The integrated design reduces assembly errors and improves overall processing accuracy and equipment reliability.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
