Description

Technical Field

[0001] This utility model relates to the field of machining equipment, and in particular to a shock absorber machining equipment. Background Technology

[0002] Magnetorheological dampers, as devices that utilize magnetorheological fluid to achieve controllable damping, are widely used in numerous fields such as automotive, aerospace, and construction. Their performance plays a crucial role in the operational effectiveness of related systems. The cylinder structure, as a core component of the magnetorheological damper, directly affects its working performance and reliability. Furthermore, the magnetorheological fluid is the key medium for damping adjustment in the damper; leakage not only reduces the damper's efficiency but can also cause contamination and corrosion to surrounding components. Therefore, the sealing performance of the cylinder structure is paramount. Under long-term piston reciprocating motion and vibration impact, the seals are prone to wear, increasing the risk of magnetorheological fluid leakage. This not only shortens the damper's lifespan but also increases maintenance costs and replacement frequency. Therefore, the machining precision and quality of the cylinder structure are extremely important.

[0003] When machining the cylinder body of a magnetorheological damper, the existing fixed clamping mechanism lacks sufficient clamping stability. When machining to the edge of the cylinder body, the force on the cylinder body and clamping mechanism increases, and the chatter effect of the clamping structure intensifies, leading to a decrease in boring accuracy and larger surface roughness in some areas, affecting the quality of the finished product. At the same time, the existing boring bar has low stiffness at the cantilever end during boring, making it prone to chatter. The contact between the boring bar and the workpiece is complex under the influence of vibration, cutting heat, and cutting force. When the machining condition of the boring bar is poor, it will damage the surface quality of the workpiece, seriously affecting the machining accuracy of the cylinder body of the magnetorheological damper. In addition, the cumulative error of the transmission and clamping mechanism makes the overall machining accuracy unable to meet the high-precision machining requirements of aerospace parts and other applications. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a shock absorber processing equipment to solve the technical problem that the cantilever end stiffness of the boring bar is low and chatter effect is easy to occur during boring operations in the prior art.

[0005] To achieve the above and other related objectives, this utility model provides a shock absorber processing equipment, including an operating table, on which a boring machine is provided for machining cylinder blocks. The shock absorber processing equipment also includes:

[0006] Multiple fixed clamping mechanisms are provided, which are arranged on the operating table, surround the cylinder body, and are used to clamp the cylinder body.

[0007] An adjustable clamping mechanism is provided, comprising a mounting plate and a plurality of flexible clamping members. The mounting plate is disposed on the operating table, and a through hole is provided in the middle of the mounting plate. The boring bar of the boring machine passes through the through hole. The plurality of flexible clamping members are disposed on the mounting plate around the through hole. The clamping end of each flexible clamping member is used to clamp or move away from the outer wall of the boring bar.

[0008] The advantages of the above technical solution are that by setting up and clamping the cylinder body around multiple fixed clamping mechanisms, the stability of the cylinder body during the machining process is ensured, and machining errors caused by unstable clamping are reduced. The flexible clamping components in the adjustable clamping mechanism can dynamically adjust the boring bar as needed. The stable clamping mechanism and the enhanced rigidity of the boring bar work together to make the machining process smoother, reduce machining interruptions and rework caused by chatter, and thus improve the machining quality.

[0009] Optionally, the plurality of the flexible clamping members are arranged radially at equal angles with respect to the axis of the boring bar.

[0010] Optionally, the flexible clamping member is a magnetorheological component, and a gripper is provided at the piston rod end of the magnetorheological component.

[0011] Optionally, the gripper has an arc-shaped structure, and the arc of the gripper is consistent with the arc of the outer wall of the boring bar.

[0012] Optionally, the fixing and clamping mechanism includes a positioning block, a telescopic rod, and a clamping block. The positioning block is used to fix it on the operating table. One end of the telescopic rod is used to connect to the positioning block, and the other end of the telescopic rod is used to connect to the clamping block. The clamping block is clamped or moved away from the outer wall of the cylinder by the telescopic movement of the telescopic rod.

[0013] Optionally, the positioning block and the telescopic rod are hinged together.

[0014] Optionally, the telescopic rod and the clamping block are hinged together.

[0015] Optionally, the fixed clamping mechanism further includes an auxiliary clamping device, which includes a support rod and a connecting rod. One end of the support rod is attached to the telescopic rod, and the other end of the support rod is connected to the connecting rod through a hinge post. The hinge post is disposed on the operating table, and the connecting rod is used to support the outer wall of the cylinder.

[0016] Optionally, an auxiliary ring is also fitted on the outer wall of the cylinder, and a locking block is also provided at the end of the connecting rod away from the support rod, the locking block being engaged with the auxiliary ring.

[0017] Optionally, an auxiliary block is provided at the end of the support rod away from the connecting rod, and the auxiliary block is used to overlap with the telescopic rod.

[0018] As described above, the shock absorber processing equipment of this utility model has the following beneficial effects: through the combined action of the fixed clamping mechanism and the adjustable clamping mechanism, the cylinder body receives comprehensive and stable support during processing. This helps to reduce processing errors caused by cylinder body swaying or vibration, thereby improving processing accuracy to meet the processing requirements of various shock absorbers.

This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportional relationships, or adjustments to the size, without affecting the effects and purposes that this utility model can produce, should still fall within the scope of the technical content disclosed in this utility model. Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in this specification are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0038] Please see Figures 1 to 2 As shown, this utility model provides a shock absorber processing equipment, including an operating table with a cylindrical structure. A boring machine is mounted on the operating table for machining cylinder blocks. The shock absorber processing equipment also includes:

[0039] Multiple fixed clamping mechanisms 2 are disposed on the inner wall of the operating table, the fixed clamping mechanisms 2 are arranged around the cylinder body, and are used to clamp the cylinder body;

[0040] The adjustable clamping mechanism 3 includes a mounting plate 301 and a plurality of flexible clamping members 302. The mounting plate 301 is disposed on the operating table. A through hole is provided in the middle of the mounting plate 301. The boring bar 1 of the boring machine passes through the through hole. The plurality of flexible clamping members 302 are disposed on the mounting plate 301 around the through hole. The clamping end of each flexible clamping member 302 is used to clamp or move away from the outer wall of the boring bar 1.

[0041] It should also be noted that multiple fixed clamping mechanisms 2 are evenly distributed around the cylinder body, ensuring the cylinder body's omnidirectional stability during processing. This layout helps reduce chatter effects caused by cylinder body wobbling.

[0042] For example, the fixing clamping mechanism 2 includes, but is not limited to, three, and correspondingly, the included angle between two adjacent fixing clamping mechanisms 2 is 120°.

[0043] Furthermore, a buffer cavity is provided inside the boring machine, through which the boring bar 1 passes. Magnetorheological fluid is injected into the buffer cavity, and an oil-blocking mechanism is provided at the connection between the buffer cavity and the boring bar 1.

[0044] For example, a plurality of the flexible clamping members 302 are arranged radially at equal angles with respect to the axis of the boring bar 1. This embodiment includes, but is not limited to, three flexible clamping members 302 arranged around the boring bar 1, and correspondingly, the included angle between two adjacent flexible clamping members 302 is 120°.

[0045] It should also be noted that by setting the flexible clamping members 302 radially at equal angles with the axis of the boring bar 1 as the center, it can be ensured that the supporting force applied to the boring bar 1 by each flexible clamping member 302 is evenly distributed. This uniform distribution helps reduce deformation or chatter of the boring bar 1 caused by uneven local force, and the radially equal angle setting allows each flexible clamping member 302 to clamp the boring bar 1 at the optimal angle and position, thereby maximizing the clamping effect. This helps improve machining accuracy and surface quality.

[0046] For example, the flexible clamping member 302 is a magnetorheological component, and a clamping claw 303 is provided at the piston rod end of the magnetorheological component.

[0047] It should also be noted that magnetorheological components are intelligent materials capable of rapidly changing their rheological properties according to the intensity of an applied magnetic field. In shock absorber processing equipment, the stiffness and damping characteristics of the magnetorheological component can be adjusted in real time by regulating the applied magnetic field. This dynamic response capability allows the flexible clamping component 302 to quickly adapt to different processing conditions and the state of the boring bar 1, providing precise clamping force.

[0048] When the boring bar 1 is subjected to an external force such as a cutting force, the flexible clamping member 302 can respond quickly and adjust the clamping force, thereby suppressing the occurrence of chatter effect.

[0049] In another exemplary embodiment, a control system is also included. The control system comprises a detection module and a control module. The detection module is used to detect the axial position and vibration force data of the boring bar 1. The detection module includes, but is not limited to, using a laser displacement sensor and an accelerometer. The laser displacement sensor is installed near the boring bar 1 to detect changes in its axial position. By measuring the change in distance between the boring bar 1 and a fixed point, the axial position information of the boring bar 1 is accurately obtained. The accelerometer is installed on the outer wall of the boring bar 1, etc., to monitor the vibration acceleration of the boring bar 1 in real time, converting the vibration signal into an electrical signal output. By analyzing and processing these signals, the vibration state of the boring bar 1, such as vibration amplitude and frequency, can be understood, and thus the vibration force experienced by the boring bar 1 can be inferred. Combining the laser displacement sensor and the accelerometer allows for both precise measurement of the axial position of the boring bar 1 and accurate acquisition of its vibration force data, providing more comprehensive and accurate monitoring information for boring operations. The control module receives the axis position and vibration force data of the boring bar 1, analyzes and processes the data, and issues control commands to adjust the magnetic field changes of the magnetorheological component, adjust the extension and retraction length of the free end of the magnetorheological component and the clamping force, thereby adjusting the axis of the boring bar 1 to ensure that the axis of the boring bar 1 is coaxial with the axis of the workpiece, thus improving the machining accuracy.

[0050] For example, the gripper 303 has an arc-shaped structure, and the arc of the gripper 303 is consistent with the arc of the outer wall of the boring bar 1.

[0051] It should also be noted that the arc-shaped gripper 303 can fit tightly against the outer wall of the boring bar 1, forming a seamless contact. This tight fit ensures that the gripper 303 can stably support the boring bar 1 during clamping, reducing vibration and deviation caused by poor contact. Since the curvature of the gripper 303 is consistent with the curvature of the outer wall of the boring bar 1, the clamping force can be evenly distributed on the outer wall of the boring bar 1. This evenly distributed clamping force helps to reduce deformation and chatter of the boring bar 1 during machining, improving machining accuracy.

[0052] For example, the fixed clamping mechanism 2 includes a positioning block 201, a telescopic rod 202, and a clamping block 203. The positioning block 201 is used to fix it on the operating table. One end of the telescopic rod 202 is used to connect to the positioning block 201, and the other end of the telescopic rod 202 is used to connect to the clamping block 203. The clamping block 203 is clamped or moved away from the outer wall of the cylinder by the telescopic extension and retraction of the telescopic rod 202.

[0053] It should also be noted that the positioning block 201 is used to fix the device to the operating table, providing a stable mounting base for the entire fixed clamping mechanism 2. The positioning block 201 ensures the accurate position of the fixed clamping mechanism 2 on the operating table, preventing displacement during processing. One end of the telescopic rod 202 is connected to the positioning block 201, and the other end is connected to the clamping block 203. Through the telescopic movement of the telescopic rod 202, the clamping block 203 can flexibly clamp or move away from the outer wall of the cylinder. This design allows the fixed clamping mechanism 2 to adapt to cylinders of different sizes and to accommodate minor displacements of the cylinder during processing.

[0054] For example, the positioning block 201 is hinged to the telescopic rod 202.

[0055] It should also be noted that the hinged connection allows the telescopic rod 202 to rotate freely within a certain range, thereby increasing the flexibility of the fixed clamping mechanism 2. This flexibility allows the clamping block 203 to better adapt to the curved shape of the outer wall of the cylinder, achieving a tighter fit and more stable clamping.

[0056] For example, the telescopic rod 202 and the clamping block 203 are hinged together.

[0057] It should also be noted that the hinged connection allows the clamping block 203 to rotate freely within a certain range, thus adapting to different shapes and curvatures of the cylinder outer wall. This adaptability allows the fixed clamping mechanism 2 to fit more closely to the cylinder outer wall, improving clamping stability and reliability. By adjusting the angle and position of the clamping block 203, precise clamping of the cylinder outer wall can be achieved. This precise clamping helps reduce vibration and deviation during machining, improving machining accuracy.

[0058] The telescopic pole 202 is an electric telescopic pole 202, and its extension and retraction can be controlled by an externally connected control module.

[0059] For example, the fixed clamping mechanism 2 further includes an auxiliary clamping device, which includes a support rod 204 and a connecting rod 205. One end of the support rod 204 is attached to the telescopic rod 202, and the other end of the support rod 204 is connected to the connecting rod 205 through a hinge column. The hinge column is disposed on the operating table, and the connecting rod 205 is used to support the outer wall of the cylinder.

[0060] It should also be noted that the auxiliary clamping device provides additional support to the outer wall of the cylinder block via the support rod 204 and connecting rod 205, effectively enhancing clamping stability. During machining, this stability helps reduce vibration and deviation, improving machining accuracy. The auxiliary clamping device also distributes the clamping force of the clamping block 203, helping to reduce damage to the outer wall of the cylinder block caused by excessive clamping force. Simultaneously, distributing the clamping force also helps improve clamping uniformity, further reducing machining errors.

[0061] Furthermore, during the machining process, the outer wall of the cylinder may deform due to uneven stress. The auxiliary clamping device provides additional support points for the outer wall of the cylinder, helping to reduce this deformation and improve machining quality.

[0062] For example, an auxiliary ring 4 is also fitted on the outer wall of the cylinder body, and a locking block 206 is also provided at the end of the connecting rod 205 away from the support rod 204, and the locking block 206 is engaged with the auxiliary ring 4.

[0063] It should also be noted that the auxiliary ring 4 is fitted onto the outer wall of the cylinder body, providing additional support points for the connecting rod 205. Fixing the connecting rod 205 to the auxiliary ring 4 via the clamping block 206 further enhances the stability of the clamping mechanism 2, preventing displacement or shaking of the cylinder body during processing. The combined use of the auxiliary ring 4 and the connecting rod 205 helps to disperse the clamping force of the clamping block 203 on the outer wall of the cylinder body. This dispersion reduces local pressure on the outer wall of the cylinder body, lowers the risk of damage, and improves the uniformity and stability of clamping. Furthermore, the star-shaped honeycomb structure rubber pad on the surface of the clamping block 206 further reduces chatter between the auxiliary ring 4 and the clamping block 206.

[0064] For example, the end of the support rod 204 away from the connecting rod 205 is provided with an auxiliary block 207, which is used to overlap with the telescopic rod 202.

[0065] It should also be noted that the auxiliary block 207 provides a more stable connection point between the support rod 204 and the telescopic rod 202. This design effectively prevents the support rod 204 from slipping or falling off under stress, thereby ensuring the stability and reliability of the clamping mechanism.

[0066] Meanwhile, a star-shaped honeycomb structure rubber pad is provided on the surface of the auxiliary block 207 to initially reduce flutter. Then, the flutter is transmitted to the telescopic rod 202 through the lever structure to increase the clamping force, realize energy conversion and utilization, passively suppress flutter and improve the clamping effect.

[0067] Furthermore, in order to make the overlap between the auxiliary block 207 and the telescopic rod 202 more stable, a corresponding overlap groove can be provided on the outer wall of the telescopic rod 202 to accommodate the auxiliary block 207.

[0068] In summary, the shock absorber processing equipment of this utility model can stably and accurately clamp the workpiece through multiple fixed clamping mechanisms 2, and adjust the stability of the boring bar with a magnetorheological adjustment device to suppress the chatter of the boring bar 1 and achieve high-precision processing, thereby improving the shock absorption effect of the magnetorheological shock absorber and the overall stability of the system.

[0069] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
