Description

Technical Field

[0001] This utility model relates to the field of front shock absorber assembly technology, specifically to an intelligent automatic assembly line for front shock absorbers. Background Technology

[0002] The front shock absorber is a key component of the car's suspension system. It is mainly used to buffer road impacts and suppress vehicle vibrations, thereby improving the vehicle's ride stability and comfort.

[0003] Traditional front shock absorber assembly processes often rely on manual or semi-automatic methods, resulting in low assembly accuracy, inefficiency, and poor product consistency. Furthermore, before final assembly, a leak test is typically performed to ensure a good seal. The process involves first conducting a leak test to confirm a good seal, then injecting oil through the oil inlet, followed by another leak test to verify continued sealing performance after oil injection. However, the traditional method typically requires two separate machines for both leak testing and oil injection, increasing equipment investment, floor space requirements, and production costs. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an intelligent automatic assembly line for front shock absorbers, so as to solve the problems that the traditional front shock absorber assembly process is mostly done manually or semi-automatically, resulting in low assembly accuracy, low efficiency and poor product consistency.

[0008] 1. By setting up multiple automated processes such as pressing dust seals, counterforce detection, plug tightening, spring installation, oil injection and pressurization, leak testing, and pressing snap rings on the same automated assembly line, the entire process of front shock absorber assembly and testing has been automated, significantly improving assembly efficiency and production cycle time.

[0009] 2.

[0036] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

They are not intended to limit the implementation conditions of this utility model and therefore have no substantial technical significance.

[0038] like Figure 1-4As shown in the figure, this utility model embodiment proposes an intelligent automatic assembly line for a front shock absorber, including a workbench 1. On the workbench 1, from left to right, are installed a pressing dust seal mechanism 2 for automatically pressing dust seals onto workpieces, a counterforce detection mechanism 3 for automatically testing the counterforce of workpieces, a plug tightening mechanism 4 for automatically tightening plugs onto workpieces, a spring mounting mechanism 5 for automatically installing springs onto workpieces, an oil injection and pressurization mechanism 6 for automatically injecting oil into workpieces, a leak detection mechanism 7 for automatically leak testing of oiled workpieces, and a pressing snap ring mechanism 8 for automatically pressing snap rings into place on workpieces. A transfer platform 9 is also installed on the workbench 1, located on one side of each mechanism, for transporting workpieces between mechanisms. Each mechanism is controlled by a controller.

[0039] In this embodiment of the invention, during operation, the workpiece first enters the press-fit dust seal mechanism 2. Under the control of this mechanism, the dust seal is accurately pressed into the designated position, ensuring the initial positioning of the sealing structure. After the dust seal press-fit is completed, the workpiece is transferred to the reaction force detection mechanism 3, which automatically detects the reaction force inside the shock absorber and compares it with a set standard to determine whether the workpiece meets the requirements. Next, the qualified workpiece is sent to the plug tightening mechanism 4, which automatically and precisely tightens the plug, ensuring the sealing structure is securely in place. Then, the workpiece enters the spring mounting mechanism 5, which automatically picks up a preset spring and installs it inside the workpiece. Subsequently, the workpiece is transported to the oil injection and pressurization mechanism 6, where a specified amount of hydraulic oil is automatically injected into the workpiece through the oil injection port, while simultaneously pressurizing to ensure uniform liquid filling. After oil injection, the workpiece is moved to the leak detection mechanism 7 for a sealing test. The system determines whether the shock absorber leaks by pressurizing, monitoring pressure changes or bubbles, etc., ensuring reliable product sealing performance. Finally, qualified workpieces enter the press-fit circlip mechanism 8, which automatically presses the circlip into the predetermined position, completing the final assembly step and ensuring the stable positioning of the elastic and sealing components.

[0040] Specifically, such as Figure 2As shown in this embodiment of the invention, the transfer platform 9 includes a slide table 91 slidably mounted on the workbench 1 along the X-axis and a plurality of gripping components 92. The gripping components 92 are arranged at intervals on the slide table 91 and cooperate with the pressing dust seal mechanism 2 and / or the counterforce detection mechanism 3 and / or the plug tightening mechanism 4 and / or the spring mounting mechanism 5 and / or the oil injection and pressurization mechanism 6 to move workpieces in or out. Each gripping component 92 includes a mounting base 921 on the slide table 91, a first cylinder 922 on the mounting base 921, a finger cylinder 923 on the extension end of the first cylinder 922, and two gripping parts 924 disposed opposite or back-to-back on the finger cylinder 923. By arranging multiple gripping components 92 at intervals, parallel transfer of multiple workpieces can be achieved, improving overall assembly efficiency. Furthermore, the gripping components 92 can be selected to operate simultaneously or alternately depending on actual cycle time requirements, ensuring efficient and coordinated connection between processes.

[0041] When the assembly line is running, the transfer platform 9 begins operation in accordance with the instructions issued by the controller. Driven by a drive device (such as a servo motor 77 or a cylinder), the slide table 91 slides back and forth along the X-axis on the worktable 1, moving several gripping components 92 between various workstations. When a workpiece needs to be transferred from one mechanism to the next, the slide table 91 moves to the target workstation's positioning position. Then, the corresponding first cylinder 922 is activated, driving the finger cylinder 923 below it to move downwards along the Z-axis to a position aligned with the workpiece. After the finger cylinder 923 is activated, its two opposing or back-to-back gripping parts 924 open and close, clamping the workpiece. After clamping, the first cylinder 922 retracts, causing the workpiece to rise and leave the workstation fixture. The slide table 91 then moves to the next workstation, and the corresponding gripping components 92 repeat the above actions, accurately placing the workpiece into the positioning position of the corresponding mechanism at the next workstation.

[0042] Based on the above scheme, in this embodiment, the transfer platform 9 further includes a support frame 93 disposed on the workbench 1. The support frame 93 is provided with a second cylinder 94. One end of the slide 91 is connected to the telescopic end of the second cylinder 94. The slide 91 is moved horizontally by the second cylinder 94, and then cooperates with the first cylinder 922 and the finger cylinder 923 to complete the gripping action. Each gripping component 92 works in coordination under the unified scheduling of the controller, thereby realizing the orderly and stable transfer of workpieces from one mechanism to the next mechanism, ensuring that the entire assembly process is efficient and automated.

[0043] Specifically, such as Figure 3As shown in this embodiment of the utility model, the oil injection and pressurization mechanism 6 includes a first frame 61, an oil injection head 63, and a first clamping fixture: the first frame 61 is disposed on the worktable 1, and a first mounting frame 62 is provided above it; the oil injection head 63 is slidably disposed on the first mounting frame 62 along the Z-axis direction to realize automatic docking and sealing pressurization of the oil injection port of the workpiece by moving up and down; the first clamping fixture is used to position and clamp the workpiece to be injected to ensure that the workpiece is stable and does not shake during the oil injection process.

[0044] After the workpiece is transported from the transfer platform 9 to the oil injection and pressurization station and placed on the first clamping fixture, the first clamping fixture activates its clamping mechanism to accurately position and securely clamp the workpiece. Subsequently, the controller issues a command to drive the oil injection head 63 to descend along the Z-axis, aligning it with the workpiece's oil injection port and ensuring a tight seal. While ensuring a sealed connection, the oil injection head 63 activates its internal oil injection unit, injecting a preset amount of hydraulic oil into the workpiece and applying appropriate pressure during the injection process to ensure the oil fills the internal cavity of the shock absorber and removes air. After oil injection is complete, the oil injection head 63 rises back to its original position, the clamping fixture releases, and the transfer platform 9 transports the oiled workpiece to the next station (i.e., the leak detection mechanism 7) for further processing.

[0045] Specifically, in this embodiment, the first clamping fixture includes a first support assembly 64 and a first clamping assembly 65: the first support assembly 64 includes a first lifting plate 641 slidably disposed on the first frame 61, a third cylinder 642 disposed on the first lifting plate 641, and a first support seat 643 disposed on the telescopic end of the third cylinder 642, for supporting one end of the workpiece; the first clamping assembly 65 includes a first clamping cylinder 651 disposed on the first mounting frame 62 and located above the first support assembly 64, and the telescopic end of the first clamping cylinder 651 is provided with two opposing or back-to-back first clamping parts 652 for pressing and fixing the other end of the workpiece.

[0046] After the workpiece is transferred from the transfer platform 9 to the oiling station, its lower end is first lifted to a predetermined height by the first support seat 643 driven by the third cylinder 642, forming a preliminary positioning. Subsequently, the first clamping cylinder 651 actuates, its clamping part descends along the Z-axis and clamps the upper end of the workpiece, achieving stable vertical positioning of the workpiece. The entire clamping process works in coordination to ensure that the workpiece does not shake or shift during the oiling process, providing stable support for the subsequent precise docking and pressurized oiling of the oiling head 63.

[0047] Specifically, such as Figure 1 and 4As shown in the embodiment of this utility model, the leak detection mechanism 7 includes a modular robot arm 71 disposed on the workbench 1, a second frame 72 disposed on the workbench 1, a second mounting frame 73 disposed on the second frame 72, a leak detection head 74 slidably disposed on the second mounting frame 73 along the Z-axis direction, and a second clamping fixture. The modular robot arm 71 is used to transport the workpiece from the transfer platform 9 to the second clamping fixture. Specifically, the modular robot arm 71 uses horizontal movement and lifting action to grab the workpiece transported from the transfer platform 9 to the vicinity of the leak detection area and accurately place it on the second clamping fixture to prepare for subsequent leak detection.

[0048] Specifically, in this embodiment, the second clamping fixture includes a second support assembly 75 and a second clamping assembly 76: the second support assembly 75 includes a second lifting plate 751 slidably disposed on the second frame 72, a fourth cylinder 752 disposed on the second lifting plate 751, and a second support seat 753 disposed on the telescopic end of the fourth cylinder 752, for supporting one end of the workpiece; the second clamping assembly 76 includes a second clamping cylinder 761 disposed on the second mounting frame 73 and located above the second support assembly 75, the telescopic end of the second clamping cylinder 761 is provided with two opposing or back-to-back second clamping parts 762, for pressing and fixing the other end of the workpiece.

[0049] After the workpiece is gripped by the module robot 71 and placed into the second clamping fixture, the fourth cylinder 752 drives the second support base 753 to rise, supporting the lower end of the workpiece. Subsequently, the second clamping cylinder 761 activates, its clamping part moves downward and clamps the upper end of the workpiece, completing the clamping and positioning of the workpiece. Next, the leak test head 74, driven by the control system, moves downward along the Z-axis to make sealing contact with the oil inlet or sealing part on the workpiece, and applies pressure to the inside of the workpiece using air / vacuum or liquid pressure to detect any leakage. After the leak test is completed, the leak test head 74 rises, the clamping mechanism releases, and the module robot 71 transfers the tested workpiece to the next process or the unloading area.

[0050] Specifically, in this embodiment, a motor 77 is provided at the bottom of the second frame 72, and a lead screw 78 is provided on the second lifting plate 751. The motor 77 is connected to the lead screw 78 to drive the lead screw 78 to rotate, thereby causing the second lifting plate 751 to slide along the Z-axis. The lead screw 78 and the motor 77 can be connected by a coupling or a synchronous pulley assembly to achieve rotation under the drive of the motor 77. The lead screw 78 and the second frame 72 are connected by a nut pair. During the rotation of the lead screw 78, the second lifting plate 751 is driven to slide up and down along the Z-axis, thereby realizing the lifting and positioning of the second support seat 753.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
