Description

Technical Field

[0001] The present invention relates to a vehicle shock absorber technology, and more specifically, to a spring disk spiral lift point height error prevention device and a control method thereof. Background Art

[0002] Most products in the prior art use two cylinders symmetrically distributed on both sides of the spring disk positioning fixture, and the spring disk spiral lift height is ensured by pressing the cylinders into place. Due to the following factors, the error prevention effect of the spring disk lift point height is poor:

[0003] 1. The height of the spiral lift point of the spring disk cannot be identified by cylinder clamping to determine whether it is qualified, and it is impossible to prevent the occurrence of defective parts.

[0004] 2. The reliability of two-point pressing is poor. It cannot be directly pressed on the specified position of the spring disk. The pressed point fits well, but the unpressed point does not fit well. The equipment cannot judge whether the positioning is in place and cannot prevent positioning errors.

[0005] 3. The cylinder being pressed into place does not reflect the actual status of the spring disk assembly. Some points are suspended, but the cylinder has been pressed into place. The equipment cannot recognize this as an abnormal situation. The welding start button and the height of the spring disk spiral lift point are not interlocked. Error prevention can be achieved directly through the cylinder, and startup error prevention cannot be achieved. Summary of the invention

[0007] To achieve the above object, the present invention provides the following technical solution: a spring disk spiral lift point height error prevention device, comprising:

[0012] The control system is connected to each mechanism through PLC and is used to control each mechanism; the control system can also remotely control the welding robot to facilitate subsequent welding work.

[0013] The present invention is further configured as follows: the clamping mechanism includes a clamping cylinder fixed to the rear side of the base, a cylinder joint that can be driven by the clamping cylinder to perform flipping movement, a clamping block fixedly connected to the cylinder joint via a positioning pin, and four clamping heads that are arranged at a designated position at the bottom of the clamping block and are integrally formed with the clamping block and are used to clamp and fix the spring disk;

[0014] The pressing block is provided with a U-shaped groove 1 for avoiding the liquid storage cylinder so that the pressing head can smoothly press the spring disk. The central axis of the U-shaped groove 1 is coaxial with the central axis of the placement rod. The ratio of the diameter of the U-shaped groove 1 to the diameter of the liquid storage cylinder is 1:0.3-1:0.5.

[0015] The present invention is further configured as follows: the positioning mechanism comprises a support frame mounted on the base, four floating positioning pins for supporting the spring disk are arranged at a designated position on the top of the support frame, and handles are arranged on both sides of the top of the support frame for easy movement;

[0016] The support frame is provided with a U-shaped groove 2 for accommodating the liquid storage cylinder, the central axis of the U-shaped groove 2 is coaxial with the central axis of the placement rod, and the ratio of the diameter of the U-shaped groove 2 to the diameter of the liquid storage cylinder is 1:0.6-1:0.8.

[0017] The present invention is further configured as follows: the detection mechanism comprises four OMRON high-precision sensors arranged at the bottom of the support frame and electrically connected to the four floating positioning pins respectively for accurately detecting the positions of the floating positioning pins;

[0018] The accuracy of the OMRON high-precision sensor is ±0.01mm, ensuring accurate detection of the position of the floating locating pin.

[0019] The present invention is further configured as follows: the clamping head is made by quenching alloy steel to ensure that the clamping head has sufficient hardness and wear resistance.

[0020] The present invention is further configured as follows: the positioning part of the floating positioning pin is made by quenching alloy steel, ensuring that the positioning part has sufficient hardness and wear resistance.

[0021] The present invention is further configured such that the rotation range of the cylinder joint is 0°-90°.

[0022] A control method for a spring disk spiral lift point height error prevention device, characterized in that it comprises the following steps:

[0023] S1. Initialize the control system: When the equipment starts working, the control system is started first, and the system performs self-check to ensure that all mechanisms are working normally. The system sets the adaptation parameters of the spring disk and the liquid storage cylinder according to the preset program;

[0024] S2. Assembling the liquid storage cylinder: After the equipment is initialized, the staff inserts the liquid storage cylinder with the spring disk into the placement rod, so that the bottom of the spring disk contacts the four floating positioning pins and ensures that the position of the liquid storage cylinder is stable and without deviation;

[0025] S3. Expanding and tightening the liquid storage cylinder: When the liquid storage cylinder is installed, the control system starts the expansion head mechanism to expand the liquid storage cylinder. The expansion head mechanism will automatically monitor the expansion force and expansion position to ensure that the expansion action is accurate;

[0026] S4, start the clamping mechanism: after the liquid storage cylinder is expanded, the control system starts the clamping mechanism, which drives the cylinder joint to flip through the clamping cylinder, so that the four clamping heads evenly apply pressure to the spring disk to ensure that the spring disk is evenly compressed. During this process, the control system monitors the clamping force and automatically adjusts it through the PLC to avoid height errors caused by uneven clamping;

[0027] S5, floating positioning pin retracts: when the clamping mechanism is activated and sufficient pressure is applied, the floating positioning pin in the positioning mechanism will automatically retract to the preset position. At this time, the control system monitors the movement of the floating positioning pin and confirms whether the floating positioning pin is in the correct position through sensor feedback;

[0028] S6, Precision position detection: When the floating locating pin is in place, the detection mechanism starts to perform precision detection. The OMRON high-precision sensor installed at the bottom of the support frame accurately measures the position of the floating locating pin and transmits the detection data back to the control system in real time;

[0029] S7, comparison of test data with preset values: the system compares the position of the floating positioning pin with the preset value based on the data sent back by the OMRON sensor. At this time, the control system will determine whether the height of the spiral lift point of the spring disk meets the requirements. When the test data fed back by the OMRON sensor deviates from the preset value, the system will automatically generate an alarm and stop subsequent operations to prevent unqualified spring disks from entering the welding process;

[0030] S8, signal feedback and automatic unlocking: When the system detects that the floating positioning pin has been accurately positioned and the data of the OMRON sensor meets the preset standard, the control system will send an unlocking signal to release the welding lock state of the equipment. At this time, the staff can manually start the welding button, and the control system is ready to enter the welding stage;

[0031] S9. Error prevention protection: During the inspection process, if the control system finds any unqualified installation, including but not limited to the spring disc not being in place and the positioning pin not being in place, the control system will automatically lock the welding button to prevent the equipment from starting the welding operation. At this time, the staff must manually check the assembly until the control system confirms that all points are installed correctly before allowing the welding operation;

[0032] S10. Complete the welding process: When the equipment completes the accurate assembly and inspection of the spring disk, the operator can press the welding start button, and the control system remotely controls the welding robot to move for welding. The control system controls the rotating table mechanism to drive the liquid storage cylinder to rotate to cooperate with the welding work. During the welding process, the control system continues to monitor to ensure the welding quality. After the welding is completed, the control system automatically terminates all work and enters a new round of process after the staff removes the liquid storage cylinder.

[0033] The beneficial effects of the present invention are:

[0034] 1. Compared with the prior art, the error-proofing device for the spiral lift point height of the spring disk of the present invention adopts multiple precise control and detection mechanisms. The rotating table mechanism on the base can accurately position the liquid storage cylinder, the expansion head mechanism can effectively fix the liquid storage cylinder and ensure its stability. The clamping mechanism applies uniform pressure by precisely controlling the four clamping heads to ensure that the spring disk is evenly clamped, thereby effectively reducing the positioning error caused by the cylinder clamping. Through the cooperation of the floating locating pin and the OMRON high-precision sensor, the precise detection of the position of the spring disk can be achieved. Once a deviation is found, the system can promptly alarm and lock the welding device to prevent unqualified products from flowing into the subsequent production process, greatly improving the accuracy and safety of assembly, and avoiding the impact of potential unqualified products on subsequent processes.

[0035] 2. The design of the clamping mechanism of the anti-error device for the spiral lift point height of the spring disk of the present invention ensures that the spring disk will not be unevenly fitted during the clamping process, reducing the problem of uneven distribution of the clamping force. The setting of the U-shaped groove 1 can avoid the liquid storage cylinder, ensuring that the clamping head can smoothly and evenly compress the spring disk, and there is enough space without affecting the welding work. The ratio of the diameter of the U-shaped groove 1 to the diameter of the liquid storage cylinder is 1:0.3-1:0.5. This ratio can ensure the smooth movement of the pressing block. If the diameter ratio is less than 1:0.3, it may cause the liquid storage cylinder to be loosely fixed and increase the positioning error. If the diameter ratio is greater than 1:0.5, it may cause the pressing block to be unable to pass smoothly and cause trouble to the subsequent welding work. Therefore, the preferred ratio of 1:0.3-1:0.5 can most effectively avoid the above problems.

[0036] 3. In the present invention, the design of the positioning mechanism adopts floating positioning pins. Through this flexible support method, it can adapt to different shapes and position changes of the spring disk. The four floating positioning pins can ensure the precise support of the spring disk and provide sufficient stability. The design of the U-shaped groove 2 is matched with the size of the liquid storage cylinder, so that the liquid storage cylinder can accurately enter the support frame and obtain effective support, avoiding the problem of deviation caused by unstable support. The ratio of the diameter of the U-shaped groove 2 to the diameter of the liquid storage cylinder is 1:0.6-1:0.8. The design within this range can take into account the adaptation problem between the spring disk and the liquid storage cylinder, avoiding poor adaptation and positioning errors caused by excessively large or small groove diameters, which affect the smoothness of the installation process.

[0037] 4. In the present invention, the detection mechanism realizes accurate detection of the position of the floating locating pin through four OMRON high-precision sensors, can monitor the precise position of each locating pin in real time during the spring disk assembly process, and perform data comparison through the PLC feedback system with an accuracy of ±0.01mm, thereby ensuring the accurate positioning of the floating locating pin and avoiding assembly problems caused by positioning errors. The high-precision sensor can eliminate interference from other external factors during the detection process to ensure the stability and reliability of the detection results. When inaccurate positioning is detected, the control system will immediately alarm to prevent unqualified products from entering the subsequent welding process, thereby improving the controllability of the production process and the qualified rate of the product.

[0043] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right" and the like are used in the embodiments to illustrate the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations of the device in use or operation.

Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0045] Figures 1 to 3 The present invention discloses a spring disk spiral lift point height error prevention device, comprising:

[0046] A base 1 is used to carry various mechanisms. A rotating platform mechanism 2 is provided on the base 1. A liquid storage cylinder placement rod 3 is installed on the rotating platform mechanism 2. An expansion head mechanism 4 for expanding and fixing the liquid storage cylinder is provided on the top of the placement rod 3;

[0047] A clamping mechanism 5 is arranged at the rear side of the base 1 and is used to clamp and fix the spring disk;

[0048] A positioning mechanism 6, disposed on the base 1 and used for positioning the supporting spring disk;

[0049] A detection mechanism 7, which is disposed at the bottom of the positioning mechanism 6 and is used for precision detection;

[0050] The control system is connected to each mechanism through PLC and is used to control each mechanism; the control system can also remotely control the welding robot to facilitate subsequent welding work;

[0051] Compared with the prior art, the error-proofing device for the spiral lift point height of the spring disk of the present invention adopts multiple precise control and detection mechanisms. The rotating table mechanism 2 on the base 1 can accurately position the liquid storage cylinder, and the expansion head mechanism 4 can effectively fix the liquid storage cylinder and ensure its stability. The clamping mechanism 5 applies uniform pressure by precisely controlling the four clamping heads 11 to ensure that the spring disk is evenly clamped, thereby effectively reducing the positioning error caused by the cylinder clamping. Through the cooperation of the floating locating pin 14 and the OMRON high-precision sensor, the precise detection of the position of the spring disk can be achieved. Once a deviation is found, the system can promptly alarm and lock the welding device to prevent unqualified products from flowing into the subsequent production process, greatly improving the accuracy and safety of assembly, and avoiding the impact of potential unqualified products on subsequent processes.

[0052] The clamping mechanism 5 includes a clamping cylinder 8 fixed to the rear side of the base 1, a cylinder joint 9 that can be driven by the clamping cylinder 8 to perform flipping movement, a clamping block 10 fixedly connected to the cylinder joint 9 via a positioning pin, and four clamping heads 11 that are arranged at a designated position at the bottom of the clamping block 10 and are integrally formed with the clamping block 10 for clamping and fixing the spring disk;

[0053] The pressing block 10 is provided with a U-shaped groove 12 for avoiding the liquid storage cylinder so that the pressing head 11 can smoothly press the spring disk. The central axis of the U-shaped groove 12 is coaxial with the central axis of the placement rod 3. The ratio of the diameter of the U-shaped groove 12 to the diameter of the liquid storage cylinder is 1:0.3-1:0.5.

[0054] The design of the clamping mechanism 5 of the spring disk spiral lift point height error prevention device of the present invention ensures that the spring disk will not be unevenly fitted during the clamping process, reducing the problem of uneven distribution of the clamping force. The setting of the U-shaped groove 12 can avoid the liquid storage cylinder, ensuring that the clamping head 11 can smoothly and evenly clamp the spring disk, and there is enough space without affecting the welding work. The ratio of the diameter of the U-shaped groove 12 to the diameter of the liquid storage cylinder is 1:0.3-1:0.5. This ratio can ensure the smooth movement of the pressure block 10. If the diameter ratio is less than 1:0.3, it may cause the liquid storage cylinder to be loosely fixed and increase the positioning error. If the diameter ratio is greater than 1:0.5, it may cause the pressure block 10 to be unable to pass smoothly, and it will also cause trouble for subsequent welding work. Therefore, the preferred ratio of 1:0.3-1:0.5 can most effectively avoid the above problems.

[0055] The positioning mechanism 6 includes a support frame 13 mounted on the base 1, four floating positioning pins 14 for supporting the spring disk are arranged at designated positions on the top of the support frame 13, and handles 15 are arranged on both sides of the top of the support frame 13 for easy movement;

[0056] The support frame 13 is provided with a U-shaped groove 16 for accommodating the liquid storage cylinder. The central axis of the U-shaped groove 16 is coaxial with the central axis of the placement rod 3. The ratio of the diameter of the U-shaped groove 16 to the diameter of the liquid storage cylinder is 1:0.6-1:0.8.

[0057] The positioning mechanism 6 also includes a copper cover 17 covering the top of the support frame 13, and the copper cover 17 is respectively provided with four positioning holes for the floating positioning pin 14 to pass through, and a round hole for the liquid storage cylinder to pass through is also provided in the middle of the copper cover 17; it can not only play a stabilizing role, but also prevent the splashing of electric sparks during welding, and prevent damage to the OMRON high-precision sensor on the support frame 13.

[0058] In the present invention, the design of the positioning mechanism 6 adopts a floating positioning pin 14. Through this flexible support method, it can adapt to different shapes and position changes of the spring disk. The four floating positioning pins 14 can ensure the precise support of the spring disk while providing sufficient stability. The design of the U-shaped groove 16 is matched with the size of the liquid storage cylinder, so that the liquid storage cylinder can accurately enter the support frame 13 and obtain effective support, avoiding the problem of deviation caused by unstable support. The ratio of the diameter of the U-shaped groove 16 to the diameter of the liquid storage cylinder is 1:0.6-1:0.8. The design within this range can take into account the adaptation problem between the spring disk and the liquid storage cylinder, avoiding poor adaptation and positioning errors caused by excessively large or small groove diameters, and affecting the smoothness of the installation process.

[0059] The detection mechanism 7 includes four OMRON high-precision sensors disposed at the bottom of the support frame 13 and electrically connected to the four floating positioning pins 14 respectively for accurately detecting the positions of the floating positioning pins 14;

[0060] The accuracy of the OMRON high-precision sensor is ±0.01mm, ensuring accurate detection of the position of the floating positioning pin 14;

[0061] The detection mechanism 7 realizes accurate detection of the position of the floating locating pin 14 through four OMRON high-precision sensors, and can monitor the precise position of each locating pin in real time during the spring disk assembly process, and perform data comparison through the PLC feedback system with an accuracy of ±0.01mm, ensuring the accurate positioning of the floating locating pin 14 and avoiding assembly problems caused by positioning errors. The high-precision sensor can eliminate interference from other external factors during the detection process to ensure the stability and reliability of the detection results. When inaccurate positioning is detected, the control system will immediately alarm to prevent unqualified products from entering the subsequent welding process, thereby improving the controllability of the production process and the product qualification rate.

[0062] The pressing head 11 is made by quenching alloy steel to ensure that the pressing head 11 has sufficient hardness and wear resistance;

[0063] The clamping head 11 is made of quenched alloy steel and has extremely high hardness and wear resistance. It can maintain stable working performance during long-term use and avoid uneven clamping or damage caused by material wear. This high-hardness design can ensure that in a high-intensity working environment, the clamping head 11 can always maintain accurate clamping force and positioning accuracy, thereby ensuring the accuracy of the spiral lift point height of the spring disk. At the same time, the high wear resistance of alloy steel also improves the service life of the entire device and reduces the maintenance cost and downtime caused by frequent replacement of the clamping head 11.

[0064] The positioning part of the floating positioning pin 14 is made by quenching alloy steel to ensure that the positioning part has sufficient hardness and wear resistance;

[0065] This design not only ensures the accuracy of the floating locating pin 14, but also effectively prevents the problem of inaccurate positioning due to wear during long-term operation. The alloy steel quenching part can still maintain its stable working state under high-intensity use, further enhancing the overall reliability of the device and avoiding errors caused by wear of the locating pin, thereby ensuring the accuracy and consistency of the spring disk assembly.

[0066] The rotation range of the cylinder joint 9 is 0°-90°;

[0067] The clamping mechanism 5 can achieve flexible flipping action, thereby ensuring that the four clamping heads 11 can apply pressure evenly, ensuring uniform clamping and precise positioning of the spring disk. This design can also avoid uneven clamping or assembly errors caused by too small or too large a limit range of the cylinder joint 9. By adjusting the rotation range, the device can adapt to spring disks of different sizes and shapes, improving the adaptability and versatility of the system. The rotation range of 0°-90° can ensure precise clamping while avoiding damage caused by mechanical interference or excessive rotation.

At this time, the control system will determine whether the height of the spiral lift point of the spring disk meets the requirements. When the detection data fed back by the OMRON sensor deviates from the preset value, the system will automatically generate an alarm and stop subsequent operations to prevent unqualified spring disks from entering the welding process;

[0077] S9. Error prevention protection: During the inspection process, if the control system finds any unqualified installation, including but not limited to the spring disc not being in place and the positioning pin not being in place, the control system will automatically lock the welding button to prevent the equipment from starting the welding operation. At this time, the staff must manually check the assembly until the control system confirms that all points are installed correctly before allowing the welding operation;

[0079] The control method of the present invention can ensure that the assembly and positioning process of the spring disk is accurate through precise control and automatic detection of each link of the equipment. When unqualified conditions are found, the system will automatically alarm and stop the welding operation to prevent unqualified products from entering the welding link, thereby improving the quality control capability of the entire production process. The intelligent and automated design of the control system greatly improves production efficiency and reduces the risk of human operational errors. Moreover, by remotely controlling the welding robot, the operational convenience and production safety are further improved.

The expansion head mechanism (4) automatically monitors the tightening force and tightening position to ensure that the tightening action is accurate; S4, start the clamping mechanism (5): after the liquid storage cylinder is expanded, the control system starts the clamping mechanism (5), and the clamping mechanism (5) drives the flip cylinder joint (9) through the clamping cylinder (8), so that the four clamping heads (11) evenly apply pressure to the spring disk to ensure that the spring disk is evenly compressed. During this process, the control system monitors the clamping force and automatically adjusts it through the PLC to avoid height errors caused by uneven clamping; S5, the floating positioning pin (14) is retracted: when the clamping mechanism (5) is activated and sufficient pressure is applied, the floating positioning pin (14) in the positioning mechanism (6) is automatically retracted to a preset position. At this time, the control system monitors the movement of the floating positioning pin (14) and confirms whether the floating positioning pin (14) is in the correct position through sensor feedback; S6, precise position detection: when the floating positioning pin (14) is in place, the detection mechanism (7) is started to perform precise detection, and the position of the floating positioning pin (14) is accurately measured by the OMRON high-precision sensor installed at the bottom of the support frame (13), and the detection data is transmitted back to the control system in real time; S7, comparison of detection data with preset value: the system compares the position of the floating positioning pin (14) with the preset value according to the data sent back by the OMRON sensor. At this time, the control system will determine whether the height of the spiral lift point of the spring disk meets the requirements. When the detection data fed back by the OMRON sensor deviates from the preset value, the system will automatically generate an alarm and stop subsequent operations to prevent unqualified spring disks from entering the welding process; S8, signal feedback and automatic unlocking: When the system detects that the floating positioning pin (14) has been accurately positioned and the data of the OMRON sensor meets the preset standard, the control system will send an unlocking signal to release the welding lock state of the equipment. At this time, the staff can manually start the welding button, and the control system is ready to enter the welding stage; S9. Error prevention protection: During the inspection process, if the control system finds any unqualified installation, including but not limited to the spring disc not being in place and the positioning pin not being in place, the control system will automatically lock the welding button to prevent the equipment from starting the welding operation. At this time, the staff must manually check the assembly until the control system confirms that all points are installed correctly before allowing the welding operation; S10. Completion of welding process: When the equipment has completed accurate assembly and inspection of the spring disk, the operator can press the welding start button, and the control system remotely controls the welding robot to move and perform welding work. The control system controls the rotating table mechanism (2) to drive the liquid storage cylinder to rotate and cooperate with the welding work. During the welding process, the control system continues to monitor to ensure the welding quality. After the welding is completed, the control system automatically terminates all work and waits for the staff to remove the liquid storage cylinder to enter a new round of process.
