Description
Technical Field
[0001] This utility model relates to the field of automotive parts, and in particular to a shock absorber valve assembly mechanism. Background Technology
[0002] As a core functional component of the automotive suspension system, the shock absorber contains valve components such as the recovery valve and bottom valve, which are the core structures used to regulate damping characteristics and determine shock absorption performance. The assembly accuracy and efficiency of the valve components directly affect the consistency of the finished product performance and the rate of mass production of the shock absorber.
[0003] Currently, most valve plate assembly tooling is a single, customized structure, meaning that one set of tooling can only be used for assembling either a reset valve or a foot valve, making it impossible to achieve compatible production of both types of valve plates. Consequently, when the production plan changes product models, the entire tooling equipment must be replaced. A single model changeover requires completing the entire process of tooling disassembly, positioning calibration, and parameter debugging, resulting in lengthy single-station model changeover times and making it difficult to meet actual production needs.
[0004] Therefore, a shock absorber valve assembly mechanism is needed to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a shock absorber valve plate assembly mechanism to achieve compatible co-line assembly of two types of valve plates of different specifications, namely the recovery valve and the bottom valve, thereby improving the production and processing speed.
[0006] To solve the above-mentioned technical problems, this utility model provides a shock absorber valve assembly mechanism, including a sliding track, a placement seat, a bearing seat, and a transfer component; The placement seat is located on one side of the sliding track and is arranged parallel to the sliding track; The support seat is disposed on the conveying end face of the sliding track; The transfer assembly is mounted above the placement base and the sliding track; The transfer assembly includes a displacement servo module and at least one set of adsorption and extraction components; The adsorption extraction component is fixedly connected to the displacement servo module; Each set of the adsorption and extraction elements includes two vacuum nozzles, and the two vacuum nozzles are of different specifications, respectively used for adsorbing thin valve plates and thick valve plates; The vacuum suction head is connected to a negative pressure air source, enabling it to adsorb and extract thin or thick valve plates located on the placement seat under the action of the displacement servo module, and then transfer and place them on the carrier seat.
[0007] Furthermore, multiple carrier seats are provided, and the multiple carrier seats are evenly and equidistantly arranged along the conveying direction of the sliding track.
[0008] Furthermore, the sliding track is a stepping conveyor rail, used to drive the bearing seat to be intermittently conveyed to the downstream pressing station.
[0009] Furthermore, limit plates are symmetrically arranged on both sides of the sliding track, and a gap is formed between the two limit plates; A positioning mandrel is provided at the center of the bearing seat, passing through the gap; The positioning mandrel is used to receive the valve plate and to limit the coaxial positioning of the valve plate.
[0010] Furthermore, the placement seat is provided with positioning needles that match the number and position of the adsorption and extraction elements; The positioning needle is used to receive the valve plate and to coaxially limit the valve plate.
[0011] Furthermore, a magnetic seat that moves along the length direction of the positioning needle is provided on one side of the placement seat; The magnetic base has a magnetic suction port surrounding the outer periphery of the positioning needle, and the magnetic suction port is used to simultaneously adsorb the multi-layer metal valve plate sleeved on the positioning needle. When the magnetic base moves to drive the valve plate to be attracted and connected to the vacuum suction head, the valve plates in each layer form a displacement difference under the magnetic attraction force and mutual friction, so that the valve plates are arranged in layers, and the valve plate at the top is individually attracted and connected to the suction end of the vacuum suction head.
[0012] Furthermore, the suction end of the vacuum suction head is provided with a flexible buffer gasket.
[0013] Furthermore, the displacement servo module includes a horizontal servo slide and a vertical lifting cylinder; The vertical lifting cylinder is fixedly connected to the moving end of the horizontal servo slide. The adsorption and extraction element is fixedly installed at the output end of the vertical lifting cylinder.
[0014] Furthermore, the horizontal servo slide and the vertical lifting cylinder are both electrically connected to the same PLC controller.
[0015] Furthermore, each of the two vacuum suction heads is independently equipped with a gas control valve, which is used to control the negative pressure adsorption or vacuum release of the vacuum suction head; The PLC controller is electrically connected to the two gas control valves.
[0016] Compared with the prior art, the present invention has at least the following beneficial effects: By setting up a transfer assembly including a displacement servo module and at least one set of adsorption extraction components, and ensuring that each set of adsorption extraction components includes two vacuum suction heads of different specifications connected to a negative pressure gas source, the same adsorption extraction component can be used to complete the adsorption extraction of thin valve plates and thick valve plates respectively. At the same time, parallel sliding rails, placement seats, and carrier seats set on the conveying end face of the sliding rails are set up. Since the vacuum suction head can stably drive the valve plate to be transferred across workstations between the placement seat and the carrier seat under the drive of the displacement servo module, the compatible automated assembly of two types of valve plates, namely the recovery valve and the bottom valve, can be completed on a single set of tooling equipment, thereby improving the production and processing speed.

[0019] The shock absorber valve assembly mechanism of this utility model will now be described in more detail with reference to the schematic diagrams, which illustrate preferred embodiments of this utility model. It should be understood that those skilled in the art can modify the utility model described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the utility model.
[0020] Furthermore, based on the teachings of this specification, those skilled in the art can form new technical solutions through cross-combination of different implementation methods without creating technical contradictions. Such variations should all be considered to fall within the protection scope of this patent.
[0021] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.
[0022] like Figure 1As shown in the figure, this utility model embodiment proposes a shock absorber valve assembly mechanism, including a sliding rail 1, a placement seat 2, a bearing seat 3, and a transfer component 4.
[0023] Limiting plates 11 are symmetrically arranged above the sliding track 1, and a gap is formed between the two limiting plates 11 to limit the bearing seat 3.
[0024] Furthermore, the sliding track 1 is a stepping conveyor rail, used to drive the bearing seat 3 to be intermittently conveyed to the downstream pressing station.
[0025] The placement seat 2 is located on one side of the sliding track 1 (e.g., Figure 1 (Illustrated as the left side), and is set parallel to the sliding track 1.
[0026] In this embodiment, the placement seat 2 is provided with positioning needles 21 that match the number and position of the adsorption extraction elements. The positioning needles 21 are used to receive the valve plate and limit the valve plate coaxially.
[0027] By setting a positioning needle 21 on the placement seat 2, the multi-layer valve plates stacked on the ground can be center-penetrated and limited, so that each layer of valve plates always maintains a coaxial stacked state, avoiding radial displacement and circumferential misalignment of the valve plates during the waiting process, and ensuring that the positional accuracy of the subsequent adsorption and extraction components is consistent in each adsorption and extraction.
[0028] It should be noted that, since there are multiple sets of adsorption extraction components in this embodiment, by matching the position and number of the positioning needle 21 with the adsorption extraction components, multiple valve plates can be adsorbed simultaneously for subsequent operations during a single adsorption extraction, thereby improving the production rate.
[0029] The support seat 3 is disposed on the conveying end face of the sliding track 1 and is used to receive the valve plate after being adsorbed and extracted by the adsorption extraction element.
[0030] The bearing seat 3 is provided with a positioning mandrel 31 that passes through the gap at the center. The positioning mandrel 31 is used to receive the valve plate and limit the valve plate coaxially.
[0031] When the adsorption and extraction component completes the adsorption and extraction of the valve plate and places it on the support seat 3, the positioning mandrel 31 can penetrate the central inner hole of the valve plate to form a stable radial constraint on the valve plate, preventing the valve plate from radially offset and circumferentially misaligned at the moment of placement and during the subsequent conveying process of the sliding track 1, and ensuring that the valve plate always maintains a precise coaxial state with the support seat 3.
[0032] To ensure a continuous flow of operations between the valve plate transfer and assembly process and the downstream pressing process, and to match the reciprocating pick-and-place rhythm of the transfer component 4, thus avoiding wasted production capacity due to intermittent waiting at a single workstation, and to ensure that the bearing seat 3 corresponds to the positioning pin 21 on the placement seat 2, multiple bearing seats 3 are provided here, and the number of bearing seats 3 matches the number of positioning pins 21. The multiple bearing seats 3 are evenly and equidistantly arranged along the conveying direction of the sliding track 1.
[0033] By using a multi-station sequential arrangement, processes such as valve plate feeding, transfer and placement, and downstream pressing can be carried out simultaneously and in parallel, effectively reducing the assembly cycle time of valve plates for a single shock absorber product. Simultaneously, the evenly spaced arrangement can be adapted to the stepping conveying logic of sliding track 1, ensuring that each conveying displacement corresponds one-to-one with the station spacing, further improving the overall production line's operational stability and batch production efficiency.
[0034] In this embodiment, the transfer component 4 is mounted above the placement seat 2 and the sliding rail 1, and is used to transfer the valve plate from the placement seat 2 to the bearing seat 3, and then to the downstream pressing station via the sliding rail 1.
[0035] Specifically, the transfer component 4 includes a displacement servo module 41 and at least one set of adsorption extraction elements, and the adsorption extraction elements are fixedly connected to the displacement servo module 41.
[0036] The displacement servo module 41 is used to provide horizontal reciprocating and vertical lifting drive for the adsorption and extraction component, so that the adsorption and extraction component can complete a stable reciprocating motion between the material picking station (i.e., the positioning needle 21) of the placement seat 2 and the material discharging station (i.e., the positioning spindle 31 on the bearing seat 3) of the sliding track 1, ensuring the repeatability of the valve plate material picking and discharging position and effectively avoiding the position deviation problem that is easily caused by manual transfer or ordinary transmission mechanism.
[0037] The displacement servo module 41 includes a horizontal servo slide and a vertical lifting cylinder. The vertical lifting cylinder is fixedly connected to the moving end of the horizontal servo slide, and the adsorption extraction component is fixedly installed at the output end of the vertical lifting cylinder. That is, through the horizontal displacement function of the horizontal servo slide and the vertical displacement function of the vertical lifting cylinder, the adsorption extraction component is precisely displaced in a two-dimensional plane above the placement seat 2 and the support seat 3.
[0038] In this embodiment, each set of adsorption extraction elements includes two vacuum suction heads 42, and the two vacuum suction heads 42 have different specifications, and are used to adsorb thin valve plates (i.e., restoration valve plates) and thick valve plates (i.e. bottom valve plates) respectively.
[0039] The vacuum suction head 42 is connected to a negative pressure air source, which enables the vacuum suction head 42 to adsorb and extract thin or thick valve plates located on the placement seat 2 under the action of the displacement servo module 41, and transfer them to the support seat 3.
[0040] Furthermore, each of the two vacuum suction heads 42 is independently equipped with a gas control valve, which is used to control the negative pressure adsorption or vacuum release of the vacuum suction head 42.
[0041] In a preferred embodiment, the suction end of the vacuum suction head 42 is provided with a flexible buffer gasket to prevent the vacuum suction head 42 from making hard contact with the valve plate during the suction process, which could cause scratches or other damage.
[0042] This device uses two vacuum suction heads 42 of different specifications to meet the adsorption and extraction needs of thin recovery valve plates and thick bottom valve plates respectively. Combined with the stable adsorption force provided by the negative pressure air source, the valve plates remain in a stable state throughout the transfer process. This avoids damage such as deformation and surface indentation of thin valve plates that are easily caused by rigid clamping, and also ensures the appearance accuracy and performance of the valve plates.
[0043] Meanwhile, when adsorbing different valve plates, there is no need to replace parts. The production switching between the two types of valve plates can be completed simply by controlling the negative pressure on and off of the corresponding vacuum suction head 42 by controlling the gas control valve and controlling the displacement of the displacement servo module 41. Compared with the existing technology, which involves tooling disassembly, repositioning and calibration and parameter debugging, the time spent on product model switching can be greatly shortened.
[0044] Furthermore, since the two vacuum suction heads 42 are driven by the same set of displacement servo modules 41, the positioning reference for picking up and unloading materials is completely unified, which can ensure the consistency of the assembly accuracy of the recovery valve and the bottom valve, avoid the problem of coaxiality deviation caused by the difference of multiple tooling references, and effectively improve the overall yield and production flexibility of valve plate assembly.
[0045] It should be noted that the horizontal servo slide and the vertical lifting cylinder are both electrically connected to the same PLC controller, and the PLC controller is also electrically connected to the two gas control valves. That is, by having the entire process uniformly scheduled by the same PLC controller, the action logic and operating parameters for each transfer and assembly can be completely consistent, eliminating random errors caused by manual operation and effectively improving the stability of valve assembly quality.
[0046] To better understand the operation of this device, the method of using this utility model is described here, specifically including the following steps: First, the vertical lifting cylinder drives the adsorption extraction component to descend to the top of the placement seat 2 and align with the positioning needle 21. With the help of the negative pressure air source, the valve plate is adsorbed and grasped. Then, the valve plate is vertically lifted. Next, the horizontal servo slide drives the adsorption extraction component to move horizontally to the top of the support seat 3. Then, the vertical lifting cylinder drives the adsorption extraction component to descend again to align with the positioning spindle 31 of the support seat 3. By controlling the cut-off of the negative pressure air source, the valve plate is sleeved on the positioning spindle 31. After release, it is reset to the initial picking position. By repeating this cycle, the continuous transfer operation of the valve plate can be realized.
[0047] It should be noted that during the movement of the adsorption extraction component, the sliding track 1 will synchronously step forward to transport the carrier 3 carrying the valve plate to the downstream pressing station.
[0048] like Figure 2 and Figure 3 As shown, in order to avoid the valve pieces from sticking together due to their tight surface when stacked, which could lead to multiple valve pieces being pulled out during a single material retrieval and ultimately interfere with assembly accuracy and process cycle, a magnetic seat 5 that moves along the length direction of the positioning needle 21 is provided on one side of the placement seat 2.
[0049] The magnetic base 5 has a magnetic suction port 51 surrounding the outer periphery of the positioning needle 21. The magnetic suction port 51 is used to synchronously adsorb the multi-layer metal valve plate sleeved on the positioning needle 21.
[0050] Furthermore, when the magnetic base 5 moves to drive the valve plate to be attracted and connected to the vacuum suction head 42, the valve plates in each layer form a displacement difference under the magnetic attraction force and mutual friction, so that the valve plates are arranged in layers, and the valve plate at the top is individually attracted and connected to the suction end of the vacuum suction head 42.
[0051] By setting up a liftable magnetic base 5, the valve plates are mechanically and automatically separated through the combination of magnetic attraction and interlayer friction. During the magnetic movement, the valve plates experience different magnetic forces due to their varying distances from the magnetic source. Combined with their own weight and interlayer friction resistance, the movement speed and displacement of each layer of valve plates are inconsistent, resulting in a relative displacement difference. This causes the originally tightly fitted valve plates to separate layer by layer, ultimately presenting a layered arrangement. This ensures that the vacuum suction head 42 can stably extract individual valve plates, preventing multiple plates from sticking together. Since this device does not require additional air blowing or prying separation structures, it simplifies the overall tooling layout. Compared to external force separation methods, it also effectively avoids surface scratches and damage to the valve plates.
[0052] Meanwhile, the layered material handling is highly stable and can adapt to metal valve plates of different thicknesses, further enhancing the mechanism's compatibility with multiple types of valve plates and ensuring the reliability and cycle stability of the material handling process during continuous production.
[0053] This device, by setting up a single adsorption extraction component including two vacuum suction heads 42 of different specifications, in conjunction with a displacement servo module 41 and negative pressure adsorption, realizes the collinear compatible assembly of two types of valve plates: the restoration valve plate and the bottom valve plate. It eliminates the need for tooling disassembly, positioning calibration and parameter debugging during product changeover, greatly shortens changeover time and achieves the goal of improving production speed.
[0054] Furthermore, by setting up a sliding track 1, which is a stepping conveyor guide rail, and arranging multiple bearing seats 3 at equal intervals on the conveying surface of the sliding track 1, in conjunction with the adsorption effect of the vacuum suction head 42, the valve plate picking, transfer and pressing processes are streamlined, effectively shortening the valve plate assembly cycle of a single shock absorber and further improving the production rate.
[0055] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
