Description

Technical Field

[0001] This utility model relates to the field of press-fit bushing technology, specifically a press-fit transfer device for automotive control arm bushings. Background Technology

[0002] In automotive chassis suspension systems, bushings are critical connecting components, and their assembly quality directly affects the vehicle's ride comfort, handling stability, and component lifespan. Currently, bushings need to be press-fitted to both ends of the control arm. Traditional press-fitting fixtures can only complete the press-fitting of bushings on one side. After pressing-fitting the bushing at one end of the control arm, the control arm needs to be disassembled, re-clamped, and positioned before the press-fitting operation at the other end can begin. This method is not only cumbersome but also increases positioning errors due to repeated clamping, affecting the coaxiality or positional accuracy of the bushings at both ends of the control arm. Furthermore, the repeated clamping process consumes a significant amount of time, severely reducing production efficiency and making it difficult to meet the demands of mass production. The market urgently needs a method that can clamp and simultaneously complete the press-fitting of bushings at both ends of the control arm in a single operation. Utility Model Content

[0003] This invention provides a press-fitting and transfer device for automotive control arm bushings, which can solve the problem that existing press-fitting and fixing devices can only complete the press-fitting of a single bushing, requiring the arm body to be disassembled and clamped again, resulting in low production efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a press-fitting and transfer device for automotive control arm bushings, comprising a base plate, a tooling plate movable along its length direction being provided at the upper center of the base plate, and first cylinders for driving the tooling plate to move being provided at both ends of the base plate; two bases are vertically arranged on the upper side of the tooling plate, and two second cylinders are provided on the tooling plate between the two bases; two linear slide rails are arranged side by side on the inner side of the bases, and mounting plates that can be raised and lowered along the linear slide rails are provided on the sliders of the linear slide rails; a bracket extending into the base is provided on one side of the mounting plate, and a floating mandrel is vertically arranged on the upper side of the bracket; the middle of the floating mandrel... A locating pin is vertically installed, and a first connecting plate connected to the movable end of the second cylinder is provided on the other side of the mounting plate; guide shaft supports are fixedly installed on both sides of the base, and a guide shaft is vertically installed inside the guide shaft support; a pressure head is installed directly above the floating mandrel, which can be raised and lowered, and a pressure plate is installed on the upper side of the pressure head. The cooperation between the base and the floating mandrel can realize the rapid positioning of the arm body. The locating pin and the inner hole of the bushing are precisely matched to realize the positioning of the bushing. The tooling plate serves as the carrier for transferring the bushing and the workpiece, and can move along the length of the base plate. After one end of the arm body is pressed, the tooling plate is moved to move the other base to the position of the press, and the bushing can be pressed on the other end of the arm body.

[0005] As a supplement to the technical solution described in this utility model, a self-lubricating sliding plate is provided between the tooling plate and the base plate. The self-lubricating sliding plate is connected to the base plate by bolts. The self-lubricating layer on the surface of the self-lubricating sliding plate reduces the friction coefficient between the tooling plate and the base plate, making the tooling plate move more smoothly, while reducing wear between the two and extending the service life of the tooling.

[0006] As a supplement to the technical solution described in this utility model, guide blocks are installed on both sides of the tooling plate. The guide blocks limit the tooling plate to the left and right during the movement, so that it moves in a straight line along the guide blocks.

[0007] As a supplement to the technical solution described in this utility model, a spring is sleeved on the guide shaft, and a linear bearing is slidably arranged on the guide shaft. The linear bearing is connected to the pressure plate by fasteners. The linear bearing reduces the frictional resistance when the pressure plate and the pressure head move up and down, making the pressing action more stable and smooth, while ensuring the straightness of the movement trajectory of the pressure head.

[0008] As a supplement to the technical solution described in this utility model, a support column is vertically arranged on the upper side of the tooling plate near the cylinder to perform coarse positioning of the workpiece.

[0009] As a supplement to the technical solution described in this utility model, a stop is installed on the top of the guide shaft. The stop acts as an axial limiter for the linear bearing, preventing the linear bearing from slipping off the top of the guide shaft, ensuring the fit between the linear bearing and the guide shaft, and limiting the maximum rising height of the pressure head.

[0010] As a supplement to the technical solution described in this utility model, a second connecting plate is provided on the upper side of one end of the tooling plate. The two ends of the second connecting plate are connected to the movable ends of the first cylinder. The second connecting plate connects the movable ends of the first cylinder and the tooling plate, transmitting the driving force of the two first cylinders to the tooling plate, so that the power of the two cylinders works together on the tooling plate, ensuring that the tooling plate will not generate eccentric load during the movement, and improving the stability of the transplanting process.

[0011] As a supplement to the technical solution described in this utility model, the upper end of the base is provided with a notch, the end of the arm is located in the notch, and the upper end surface of the notch supports the arm.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Linear guide rails ensure the straightness of the mounting plate during lifting and lowering, keeping the floating mandrel consistently vertical. The cooperation between the base and the floating mandrel enables rapid positioning of the arm. Precise engagement between the positioning pin and the bushing's inner hole achieves positioning. Simultaneously, the cooperation between the guide shaft and the linear bearing ensures the pressure head does not tilt during pressing. The first cylinder acts as the power source, smoothly transmitting power to the tooling plate via the second connecting plate. Synchronous drive by the two cylinders ensures even force distribution and smooth movement of the tooling plate. The self-lubricating sliding plate between the tooling plate and the base plate reduces frictional resistance, making the tooling plate move more smoothly. The support column provides auxiliary positioning and lateral support for the workpiece. Both bases simultaneously position the two ends of the arm. By moving the tooling plate with the first cylinder, the bushing at the other end can be pressed. After the press lowers, the second cylinder lowers the floating mandrel. This design facilitates easy product removal after assembly. This design solves the problem that existing pressing and fixing devices can only press-fit single-sided bushings, requiring the arm to be disassembled and repositioned, resulting in low production efficiency.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] The embodiments of this utility model relate to a press-fitting and transfer device for automotive control arm bushings, such as... Figure 1-6 As shown, the system includes a base plate 1. A tooling plate 2, movable along its length, is located on the upper center of the base plate 1. First cylinders 3, which drive the tooling plate 2, are located at both ends of the base plate 1. Two bases 4 are vertically arranged on the upper side of the tooling plate 2. Two second cylinders 10 are located on the tooling plate 2 between the two bases 4. Two linear slide rails 5 are arranged side-by-side on the inner side of the bases 4. Mounting plates 6, which can rise and fall along the linear slide rails 5, are mounted on the sliders of the linear slide rails 5. A bracket 7, extending into the base 4, is located on one side of the mounting plate 6. A floating mandrel 8 is vertically arranged on the upper side of the bracket 7. A positioning pin 9 is vertically arranged in the middle of the floating mandrel 8. The outer wall of the positioning pin 9 matches the inner hole of the bushing. On the other side of the mounting plate 6, a first connecting plate 11 is provided, which is connected to the movable end of the second cylinder 10; guide shaft supports 12 are fixedly provided on both sides of the base 4, and a guide shaft 13 is vertically provided inside the guide shaft support 12; the pressure head 14 is raised and lowered and is located directly above the floating mandrel 8. A pressure plate 15 is installed on the upper side of the pressure head 14. The cooperation between the base 4 and the floating mandrel 8 can realize the rapid positioning of the arm body. The positioning pin 9 is precisely matched with the inner hole of the bushing to realize the positioning of the bushing. The tooling plate 2 serves as the carrier for transferring the bushing and the workpiece. It can move along the length of the base plate. After one end of the arm body is pressed, the tooling plate 2 is moved to move the other base 4 to the position of the press, so that the bushing can be pressed on the other end of the arm body.

[0024] In this embodiment, as Figure 1 As shown, a self-lubricating slide plate 16 is provided between the tooling plate 2 and the base plate 1. The self-lubricating slide plate 16 is an outsourced component, brand name Misumi, model SPNG150-250. The self-lubricating slide plate 16 is connected to the base plate 1 by bolts. The self-lubricating layer on the surface of the self-lubricating slide plate 16 reduces the coefficient of friction between the tooling plate 2 and the base plate 1, making the tooling plate 2 move more smoothly, while reducing wear between the two and extending the service life of the tooling.

[0025] In this embodiment, as Figure 4 As shown, guide blocks 17 are installed on both sides of the tooling plate 2. The guide blocks 17 limit the tooling plate 2 to move left and right during the movement, so that it moves in a straight line along the guide blocks 17.

[0026] In this embodiment, as Figure 4As shown, a spring 18 is sleeved on the upper part of the guide shaft 13, and a linear bearing 19 is slidably arranged on the guide shaft 13. The linear bearing 19 is connected to the pressure plate 15 by fasteners. The linear bearing 19 reduces the frictional resistance when the pressure plate 15 and the pressure head 14 move up and down, making the pressing action more stable and smooth, while ensuring the straightness of the movement trajectory of the pressure head 14. The spring 18 plays a buffering role, absorbing the impact force of pressing and avoiding damage to the arm body and bushing. At the same time, the pressure plate 15 is reset after pressing is completed.

[0027] In this embodiment, as Figure 6 As shown, a support column 20 is vertically installed on the upper side of the tooling plate 2 near the cylinder 3 to perform coarse positioning of the workpiece.

[0028] In this embodiment, as Figure 4 As shown, a stop 21 is installed on the top of the guide shaft 13. The stop 21 plays an axial limiting role for the linear bearing 19, preventing the linear bearing 19 from slipping off the top of the guide shaft 13, ensuring the fit between the linear bearing 19 and the guide shaft 13, and limiting the maximum rising height of the pressure head 14.

[0029] In this embodiment, as Figure 2 As shown, a second connecting plate 22 is provided on the upper side of one end of the tooling plate 2. The two ends of the second connecting plate 22 are connected to the movable ends of the first cylinder 3. The second connecting plate 22 connects the movable ends of the first cylinder 3 and the tooling plate 2, transmitting the driving force of the two first cylinders 3 to the tooling plate 2, so that the power of the two cylinders works together on the tooling plate 2, ensuring that the tooling plate 2 will not generate eccentric load during the movement, and improving the stability of the transplanting process.

[0030] In this embodiment, as Figure 6 As shown, the upper end of the base 4 is provided with a notch 41, the end of the arm is located in the notch 41, and the upper end face of the notch 41 supports the arm.

[0031] In this embodiment, as Figure 1As shown, during the press-fitting operation of the bushings at both ends of the boom body, the two ends of the boom body to be press-fitted are placed in the notches 41 at the upper ends of the two bases 4. The holes at the ends of the boom body are fitted onto the floating mandrel 8. The upper end face of the notch 41 supports the boom body, achieving rapid positioning of that end of the boom body. The bushing to be press-fitted is placed on the upper side of the floating mandrel 8. The positioning pin 9 precisely matches the inner hole of the bushing, achieving the positioning of the bushing and preventing the bushing from rotating or shifting during press-fitting. The press is driven, and the pressure plate 15 and the pressure head 14 move downward. Under the guidance of the guide shaft 13 and the linear bearing 19, the pressure head 14 smoothly contacts the bushing and continues to apply pressure, pressing the bushing into the press-fitting hole of the boom body. During the press-fitting process, the movable end of the second cylinder 10 drives the mounting plate 6 to move downward along the linear slide rail 5 through the first connecting plate 11. The mounting plate 6 drives... The bracket 7, along with the floating mandrel 8 and bushing on it, descends together until the bushing enters the hole at that end of the arm. After the bushing at one end of the arm is press-fitted, the first cylinder 3 is activated. The movable end of the first cylinder 3 drives the tooling plate 2 to move along the self-lubricating slide plate 16 via the second connecting plate 22, moving the base 4 at the other end of the arm to the press position for bushing press-fitting at the other end of the arm. After the bushings at both ends of the arm are press-fitted, the press drives the press head 14 to return to its original position. The floating mandrel 8 is located inside the base 4, making it convenient for the operator to remove the assembled arm from the tooling for the next arm press-fitting operation. Throughout the operation, the method of one clamping and two press-fitting operations via moving the tooling plate 2 avoids the time wasted by repeated clamping and greatly improves processing efficiency. At the same time, the design of simultaneous positioning of the bases 4 on both sides ensures that the arm is subjected to uniform force on the tooling, is less prone to deformation, and guarantees the product qualification rate.

[0032] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0033] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.

[0034] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
