Description

Technical Field

[0001] The present invention belongs to the technical field of shock absorber bottom valve installation, and particularly relates to a spring piece installation tooling. Background Art

[0002] In the bottom valve structure of modern shock absorbers, the star-shaped spring piece is a key component. It realizes the effective control of hydraulic oil through functions such as energy conversion and absorption, control of fluid flow, and cooperation with the bottom valve. The correct installation of the star-shaped spring piece is crucial for the performance of the shock absorber.

[0003] In the prior art, the installation of the star-shaped spring piece mainly relies on manual methods. During the installation process, workers need to fix the six corners of the star-shaped spring piece to the bottom valve body in sequence. However, this manual installation method has the following main problems:

[0004] Low efficiency: The manual assembly process depends on the skills and speed of workers. Each installation requires workers to fix the corners of the star-shaped spring piece one by one, with cumbersome operations and time-consuming.

[0005] Unstable quality: During the manual installation process, the pressure applied each time is inconsistent, which easily causes the star-shaped spring piece to deform due to excessive force, thus affecting the overall performance of the shock absorber.

[0006] Impact on human health: During the installation process, workers need to exert continuous force for a long time, which easily causes hand fatigue and discomfort, and will have a negative impact on the health of workers in the long run.

[0007] High training and maintenance costs: Manual assembly requires workers to have certain skills and knowledge, which not only increases the training time but also may require more maintenance and management costs.

[0008] The above problems not only reduce the production efficiency but also affect the quality of the shock absorber and the health of workers. Therefore, there is an urgent need for a new installation method that can improve the installation efficiency, stabilize the installation quality, reduce the labor intensity of workers, and at the same time reduce the training and maintenance costs. Summary of the Invention

[0009] Aiming at the deficiencies in the related technologies, to solve the technical problems of low manual assembly efficiency, unstable quality, and low yield rate in the installation process of the star-shaped spring piece in the prior art during the installation of the shock absorber bottom valve. The present invention provides a spring piece installation tooling.

[0010] In a possible implementation, a spring piece installation tooling includes: a base, a support tooling, a tooling main body, a pressure handle, a transmission mechanism, a pressure column, and a pressing tooling. Among them, the base is disposed opposite to the tooling main body, the support tooling is installed on the base, and the bottom valve body, check valve, and star spring piece to be installed are placed on the support tooling. The bottom valve body is placed on the support tooling, the check valve is placed inside the bottom valve body, the star spring piece is placed on the check valve, and the central area of the star spring piece contacts the check valve. The pressure column is installed on the tooling main body, and the pressing tooling is installed at one end of the pressure column corresponding to the support tooling. The pressure handle and the transmission mechanism are installed on the tooling main body, the pressure handle is connected to the pressure column through the transmission mechanism, and the pressure handle drives the pressure column and the pressing tooling to press down and lift through the transmission mechanism. When the pressing tooling presses down, it contacts at least a part of the outer peripheral area of the star spring piece, so that the outer periphery of the star spring piece bends downward under the pressure of the pressing tooling and the check valve below the star spring piece.

[0011] In a possible implementation, the center lines of the pressing tooling and the support tooling are located on the same axis.

[0012] In a possible implementation, the pressing tooling is a toroid, and the contact surface between the pressing tooling and the star spring piece is an inclined surface, and the direction of the inclined surface is the direction in which the star spring piece presses down.

[0013] In a possible implementation, the pressing tooling is detachably connected to the pressure column.

[0014] In a possible implementation, the pressing tooling has three or more pressing heads, and the pressing heads are evenly distributed on a circumference with the center of the pressing tooling as the center of the circle.

[0015] In a possible implementation, the transmission mechanism is a gear structure, including a bevel gear connected to the pressure handle and a spur gear disposed on the pressure column, and the bevel gear and the spur gear are meshed.

[0016] In a possible implementation, the base is fixedly or detachably connected to the tooling main body.

[0017] Based on the above technical solution, for the spring piece installation tooling of the present utility model, the base and the tooling main body are oppositely arranged, the supporting tooling is installed on the base, and the supporting tooling is used to fix the bottom valve body and the check valve and support the star spring piece; the pressure column is installed on the tooling main body, and the press-fitting tooling is installed at one end of the pressure column; the pressure handle and the transmission mechanism are installed on the tooling main body, and the pressure handle drives the pressure column and the press-fitting tooling to move up and down through the transmission mechanism; the star spring piece is placed on the check valve to ensure that the central area of the star spring piece contacts the check valve; as the press-fitting tooling presses down, the outer periphery of the star spring piece bends downward under the dual action of the press-fitting tooling and the lower check valve, and the operator adjusts the angle of the bottom valve body to make the star spring piece snap into the groove of the bottom valve body, completing the installation of the star spring piece; ensuring the precise positioning and uniform stress of the star spring piece during the installation process, thus effectively solving the problems of low efficiency and insufficient precision in the traditional manual installation process and improving the installation quality and stability.

Thus, the features defined with "first", "second", "third" may explicitly or implicitly include one or more of such features.

[0032] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0033] In order to solve the technical problems of low manual assembly efficiency, unstable quality, and low yield rate in the installation process of the star spring piece in the installation of the bottom valve of the shock absorber in the prior art. This application proposes a spring piece installation tooling.

[0034] See Figure 1 、 Figure 2 and Figure 3, in a possible implementation, the spring piece installation tooling includes: a base 1, a support tooling 2, a tooling main body 4, a pressure handle 5, a transmission mechanism, a pressure column 6, and a press-fitting tooling 3; wherein, the base 1 is disposed opposite to the tooling main body 4, the support tooling 2 is installed on the base 1, and the bottom valve body 9, check valve 8, and star spring piece 7 to be installed are placed on the support tooling 2; the bottom valve body 9 is placed on the support tooling 2, the check valve 8 is placed inside the bottom valve body 9, the star spring piece 7 is placed on the check valve 8, and the central region of the star spring piece 7 is in contact with the check valve 8; the pressure column 6 is installed on the tooling main body 4, and the press-fitting tooling 3 is installed at one end of the pressure column 6 corresponding to the support tooling 2; the pressure handle 5 and the transmission mechanism are installed on the tooling main body 4, the pressure handle 5 is connected to the pressure column 6 through the transmission mechanism, and the pressure handle 5 drives the pressure column 6 and the press-fitting tooling 3 to move downwards and upwards through the transmission mechanism; when the press-fitting tooling 3 moves downwards, it contacts at least a part of the outer peripheral region of the star spring piece 7, causing the outer periphery of the star spring piece 7 to bend downwards under the pressure of the press-fitting tooling 3 and the check valve 8 below the star spring piece 7.

[0035] In the above solution, through the linkage of the pressure handle 5 and the transmission mechanism, the up and down movement of the pressure column 6 and the press-fitting tooling 3 is driven, thereby realizing the precise press-fitting of the star spring piece 7; the bottom valve body 9 and the check valve 8 are fixed on the support tooling 2. When the press-fitting tooling 3 moves downwards, the outer peripheral region of the star spring piece 7 is subjected to pressure and bends downwards, enabling it to be installed into the groove of the bottom valve body. When the pressure column 6 and the press-fitting tooling 3 are lifted, after the star spring piece 7 rebounds due to stress, it is clamped in the groove of the bottom valve body 9, realizing the installation of the star spring piece 7 with the check valve 8 and the bottom valve body 9.

[0036] This spring piece installation tooling simplifies the installation process of the star spring piece 7, improves the installation efficiency and accuracy; through the pressure handle 5 and the transmission mechanism, the operation is more convenient, reducing the error of manual operation; in addition, the entire installation process is stable and reliable, ensuring good contact and fixation between the star spring piece 7 and the check valve 8, and improving the installation quality and service life.

[0037] The press-fitting tooling 3 and the support tooling 2 can be adjusted according to different specifications of the star spring piece to ensure adaptation to the installation requirements of star spring pieces of different sizes. The transmission mechanism can adopt other forms of mechanical transmission devices, such as hydraulic transmission or electric transmission, to meet different operating environments and requirements. In addition, the pressure handle 5 can be designed in different shapes and lengths to adapt to the usage habits and mechanical requirements of different operators.

[0038] In a possible implementation, the center lines of the press-fitting tooling 3 and the support tooling 2 are located on the same axis.

[0039] By aligning the centerlines of the press-fitting tooling 3 and the supporting tooling 2, the stability and precision during the press-fitting process are ensured; the problems of offset and deformation of the star-shaped spring piece 7 caused by the centerline offset during the press-fitting process are avoided. The installation precision is improved, ensuring that the star-shaped spring piece 7 can be accurately press-fitted into the groove of the bottom valve body 9, thus guaranteeing the reliability and durability after installation. At the same time, this alignment design simplifies the installation process and improves work efficiency.

[0040] In a possible implementation, the press-fitting tooling 3 is a toroid, and the contact surface between the press-fitting tooling 3 and the star-shaped spring piece 7 is an inclined surface, and the direction of the inclined surface is the direction in which the star-shaped spring piece 7 is pressed down.

[0041] See Figure 4 , the contact surface between the toroidal press-fitting tooling 3 and the star-shaped spring piece 7 is designed as an inclined surface. By using the inclined surface, during the press-fitting process, the star-shaped spring piece 7 can be uniformly stressed, thus avoiding deformation or damage caused by local stress concentration. The inclined surface design makes the installation process smoother and further improves the installation precision and reliability.

[0042] In a possible implementation, the press-fitting tooling 3 is detachably connected to the pressure column 6.

[0043] The detachable connection enables the press-fitting tooling 3 to be conveniently removed from or installed on the pressure column 6; this setting facilitates the replacement of press-fitting tooling 3 of different specifications or shapes to adapt to the installation requirements of different star-shaped spring pieces 7; it improves the adaptability and flexibility of the tooling.

[0044] The detachable connection can be set to different connection mechanisms, such as threaded connection, quick plug connection, etc., to meet different disassembly and assembly requirements.

[0045] See Figure 4a , in a possible implementation, the press-fitting tooling 3 has three or more press-fitting heads 31, and the press-fitting heads 31 are evenly distributed along the circumference with the center of the press-fitting tooling 3 as the center of the circle.

[0046] The multiple press-fitting heads 31 are evenly distributed on the circumference, so that during the press-fitting process, the star-shaped spring piece 7 can be subjected to uniform pressure, avoiding the problem of uneven stress caused by a single press-fitting head, thus ensuring the stability and reliability of the installation and making the installation of the star-shaped spring piece 7 more stable and flat.

[0047] The number and distribution of the press-fitting heads 31 can be adjusted according to actual needs, designed with more or fewer press-fitting heads to adapt to different star-shaped spring pieces and installation conditions; at the same time, the shape and material of the press-fitting heads can also be adjusted according to the installation working conditions to meet actual needs.

[0048] See Figure 5, the supporting tooling 2 includes a base and a mandrel, which is adapted to the inner diameter of the bottom valve body 9. The supporting tooling 2 is detachably installed on the base 1 to match the installation of different models of bottom valve bodies and star spring washers.

[0049] See Figure 6 , in a possible implementation manner, the transmission mechanism is a gear structure, including a bevel gear 51 connected to the pressure handle 5 and a spur gear 61 provided on the pressure column 6. The bevel gear 51 and the spur gear 61 are meshed.

[0050] The force of the pressing handle 5 is transmitted to the pressure column 6 through the gear structure to realize the up and down movement of the pressing tooling 3.

[0051] In a possible implementation manner, the base 1 is fixedly or detachably connected to the tooling main body 4.

[0052] The base 1 and the tooling main body 4 can adopt a fixed connection or a detachable connection method to ensure flexible adjustment under different operation requirements. The integral or fixed connection structure is convenient for the operator to move and use, with better convenience, while the detachable connection is more flexible.

[0053] Flexibly selecting the connection method between the base 1 and the tooling main body 4 improves the adaptability and flexibility of the tooling; at the same time, it is convenient for the transportation, installation and maintenance of the tooling.

[0054] The spring washer installation tooling of the present utility model is not only applicable to the installation of star spring washers, but also applicable to the installation of spring washers in other structural forms.

[0055] The spring washer installation tooling of an embodiment of the present invention is described in detail as follows;

[0056] The star spring washer installation tooling is used to replace manual assembly. It uses manual operation as the power and can work without an external power supply. Through the designed special tooling, the slight bending of the star spring washer can be controlled to complete the assembly, avoiding permanent deformation caused by excessive force. It has the characteristics of simple operation, high flexibility and strong applicability. The structure of this tooling is shown in Figure 1 :

[0057] 1. Main body part: The base 1 and the tooling main body 4 are made of metal materials and serve as the basic part of the manual press, providing a stable support for the entire device. This design ensures that the press will not shake or displace due to uneven force or external force during operation, thus ensuring the stability and accuracy of the work.

[0058] 2. Transmission device: It includes a pressure handle 5, a pressure column 6 and its internal gear structure. See Figure 6,; It includes a bevel gear 51 connected to the pressure handle 5 and a spur gear 61 provided on the pressure column 6, and the bevel gear 51 meshes with the spur gear 61. The operator holds the pressure handle and provides power by applying a downward force. The force is transmitted to the pressure column through the pressure handle and the gear structure to complete the press-fitting of the star-shaped spring piece.

[0059] 3. Tooling: It consists of a press-fitting tooling 3 and a supporting tooling 2. The supporting tooling 2 can ensure that the workpiece is on the same axis as the upper press-fitting tooling 3 during the press-fitting process, and at the same time plays a supporting role for the workpiece to facilitate the completion of the assembly process. The press-fitting tooling 3 generates bending by applying pressure to the workpiece, thereby completing the installation process of the star-shaped spring piece

[0060] For the specific installation process, refer to Figure 2 :

[0061] During assembly, first place the bottom valve body 9 at the bottom of the supporting tooling 2, place the check valve 8 on the top of the supporting tooling 2, fit the central hole of the star-shaped spring piece 7 with the top protrusion of the check valve 8, press the pressure handle 5, and use the transmission device to lower the press-fitting tooling 3. After pressing the star-shaped spring piece 7 to the appropriate position, lift the bottom valve body 9 to complete the installation process of the star-shaped spring piece.

[0062] The working principle is as Figure 3 : When the press-fitting tooling 3 descends and contacts the star-shaped spring piece 7, it causes the star-shaped spring piece to bend downward so as to fit the arc surface on the upper part of the check valve 8. At this time, tilt the bottom valve body 9 about 15° and lift it. First, install the two feet of the star-shaped spring piece 7 into the grooves. After translating the bottom valve body 9 so that the remaining feet of the star-shaped spring piece 7 completely enter the groove range, straighten the bottom valve body 9, and lift the pressure handle 5 to drive the press-fitting tooling 3 to return. After the pressure on the star-shaped spring piece 7 disappears, it rebounds to the horizontal. At this time, the star-shaped spring piece 7 is completely installed in the groove of the bottom valve body 9 to complete the assembly process.

[0063] If star-shaped spring pieces of different sizes need to be installed, only the corresponding press-fitting tooling and supporting tooling need to be replaced to complete the model change operation.

[0064] The spring piece installation tooling of the present utility model can automatically install the six corners of the star-shaped spring piece into the bottom valve body in sequence. This mechanism should be able to accurately control the pressure during the installation process to ensure that the star-shaped spring piece does not deform.

[0065] To ensure that the star-shaped spring piece can be accurately installed into the bottom valve body, the supporting tooling, the press-fitting tooling are coaxially arranged with the centers of the bottom valve body, the check valve and the star-shaped spring piece, realizing the precise positioning of the star-shaped spring piece with the check valve and the bottom valve body, and being able to accurately match the star-shaped spring piece and the bottom valve body.

[0066] During the installation process, a safety protection mechanism is set up. Refer to Figure 3a, the inner diameter of the circular ring at the lower part of the press-fitting tooling 3 is smaller than the end face diameter of the check valve 8 below. When the upper press-fitting tooling 3 is pressed until it is completely fitted with the star-shaped spring piece 7 and the check valve 8, the deformation of the star-shaped spring piece 7 is also within the controllable range to avoid excessive deformation caused by operation errors.

[0067] 1. The star-shaped spring piece installation tooling of the present utility model can quickly and accurately position and clamp the workpiece, reducing the time for manual adjustment. Compared with manual assembly, the special tooling can work continuously and stably, can quickly complete the assembly task of the workpiece, is not affected by human factors, and ensures the stability and continuity of production efficiency.

[0068] 2. Using this tooling can reduce the problem of deformation failure of the star-shaped spring piece caused by excessive deformation that may occur during the processing, and improve the overall quality and consistency of the product.

[0069] 3. Using this tooling can reduce the labor intensity of workers, improve the working environment, and increase the job satisfaction of workers.

[0070] 4. Because of its intuitive design and easy operation, this tooling is not only easy to use but also very convenient to train. This is particularly important in a fast-paced working environment because it allows employees to quickly engage in actual work, thereby improving the overall work efficiency.

[0071] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: still modifications can be made to the specific implementation manners of the present invention or equivalent replacements can be made to some technical features; without departing from the spirit of the technical solutions of the present invention, they should all be covered within the scope of the technical solutions claimed by the present invention.
