Description

TECHNICAL FIELD

[0001] The present application relates to the field of automobile parts assembly, in particular to a subframe sleeve pressing equipment. BACKGROUND

[0002] The shock absorbing bushing is a commonly used automobile part, which is widely used in the suspension system of the automobile. As an important component of the automobile suspension system, the shock absorbing bushing can protect other suspension components. It can reduce the wear and vibration of each component in the suspension system, and improve the service life of the entire suspension system.

[0003] The bushing can absorb and reduce the vibration and bumping generated during the driving of the automobile through the characteristics of its elastic material, providing a smooth suspension effect, making the vehicle more comfortable and stable during driving. As the automobile drives, the suspension system of the automobile will produce some noise, and the shock absorbing bushing can reduce these noises by reducing the friction and vibration with the ground, providing a more quiet riding environment. The shock absorbing bushing provides appropriate elasticity, which can effectively control the attitude adjustment of the automobile during acceleration, braking and turning, improving the stability and safety of driving.

[0004] At present, the bushing is mostly pressed in the way, and the related prior art such as Chinese patent application "bushing pressing machine", application number: CN201210580185.9, discloses a machine frame, a work turntable, a connecting rod hydraulic clamp, a connecting rod small hole positioning device, a connecting rod small hole inner surface heating device, a bushing feeding device, a bushing pressing device, a bushing guiding device; the work turntable is fixed on the machine frame and located at the center of the equipment, and is provided with three workstations, including a connecting rod loading and unloading workstation, a connecting rod small hole heating workstation and a bushing pressing workstation, the connecting rod hydraulic clamps are evenly distributed and installed on the work turntable, and rotate around the center shaft together with the work turntable; the connecting rod small hole inner surface heating device, the bushing feeding device and the bushing pressing device are distributed around the work turntable, and the clamped connecting rod rotates one circle with the turntable to complete the pressing work of the connecting rod small hole bushing.

[0005] But the present application relates to the subframe structure which is relatively large in size, and the bushing needs to be installed at many places, and the structure of the bushing is as shown in Figure 1 The metal piece is assembled on the bushing. If a punching device is arranged at each assembly position of the bushing, the production cost of the entire sleeve pressing equipment will be high, and the floor area will be large. Moreover, because each subframe to be installed has a certain structural error, the installation hole positions of each bushing to be installed arranged on the surface may also be deviated. Therefore, the sleeve pressing machine with fixed assembly position has certain limitations, and further improvement is needed. SUMMARY

[0006] The technical problem to be solved by the present application is to provide a sub-frame sleeve pressing equipment, which is provided with a floating seat and can adapt to the installation hole of the sub-frame with a certain deviation; and a rotating platform is arranged to rotate the bushing and the sub-frame to the pressing position to cooperate with the pressing process.

[0007] The technical scheme adopted by the present application is as follows: a sub-frame sleeve pressing equipment comprises a rotating platform connected with a servo motor and a stamping device arranged on one side of the rotating platform, the rotating platform is provided with a pressing assembly for fixing the sub-frame and a floating seat, the sub-frame is fixed on the rotating platform by the pressing assembly, the installation hole of the sub-frame is arranged on the floating seat, the floating seat is deformed under stress, the servo motor drives the rotating platform to rotate and move the floating seat to below the stamping device, and the stamping device works to press the bushing into the installation hole of the sub-frame.

[0008] Compared with the prior art, the present application has the following advantages: firstly, for the installation of the sub-frame, the present application is provided with the pressing assembly and the floating seat. The pressing assembly fixes the entire sub-frame on the rotating platform, and the floating seat is arranged to install the installation hole on the sub-frame, which facilitates the subsequent pressing of the bushing on the installation hole. If the installation hole on the sub-frame is deviated, the installation hole is arranged on the floating seat, the floating seat is deformed under stress, and the floating seat adapts to the position of the installation hole. Secondly, the present application is provided with the rotating platform, and the stamping device is arranged on one side of the rotating platform. Therefore, for the multiple installation positions on the sub-frame, it is not necessary to match the stamping device for each installation position, but the floating seat to be pressed is rotated to below the stamping device. This reduces the number of stamping devices and greatly reduces the floor area occupied by the entire sleeve pressing equipment.

[0009] In some embodiments of the present application, the floating seat comprises a base and a mounting seat, the base is fixed on the rotating platform, the installation hole on the sub-frame is arranged on the mounting seat, the base and the mounting seat are connected through a floating assembly, and the mounting seat can move relative to the base under stress.

The calibration assembly of the present application extends out of the channel and is connected with the bushing, which can ensure that the relative position between the bushing and the installation hole of the sub-frame is accurate, and assists the subsequent pressing process of the bushing.

[0011] In some embodiments of the present application, the floating assembly or mounting base is connected with a guide auxiliary assembly, the guide auxiliary assembly comprises a guide block connected with a guide cylinder, the guide block is connected with a bushing pressing head, the bushing pressing head is matched with a calibration assembly to install the bushing; when the mounting base moves to below the stamping device, the stamping device moves downward to act on the bushing pressing head, and then the guide cylinder works to drive the guide block to move downward with the bushing pressing head. By connecting the bushing pressing head with the guide auxiliary assembly, the bushing pressing head and the position of the mounting base are synchronized. In the present application, the bushing pressing head needs to cooperate to install the bushing to be installed, and also needs to move downward synchronously with the stamping device. Therefore, in the present application, the guide auxiliary assembly is designed, the guide block connected with the guide cylinder is designed to connect the bushing pressing head, and the guide block also shrinks downward when the stamping device is pressed down, thereby realizing the assembly of the bushing.

[0012] In some embodiments of the present application, the bushing pressing head comprises a pressing seat, two sliding blocks are symmetrically installed on the pressing seat, one end of the two sliding blocks is located in the pressing seat as a connecting end, the other end of the two sliding blocks penetrates out of the pressing seat as an extending end, a gasket is connected to the extending end of the sliding block, and a space for the end of the metal sheet to extend into exists between the gasket and the bottom surface of the pressing seat.

[0013] The structure of the bushing to be pressed in the present application is shown in Figure 1 Compared with the ordinary bushing structure, the metal piece is further provided on the end portion, and the rubber connected with the metal piece will be deformed to a certain extent during the entire pressing process, thereby causing the position and angle of the metal sheet to be deviated to a certain extent. Therefore, attention needs to be paid to the fact that the metal piece will not be bent during the pressing of the bushing.

[0014] Therefore, the present application sets a space between the gasket and the bottom surface of the pressing seat, so that the end of the metal sheet can extend into the space between the gasket and the bottom surface of the pressing seat. In the present application, the gasket is located below the metal sheet, thereby playing a role in protecting the bushing metal piece. Damage to the gasket during the pressing process can be avoided. Moreover, the connection between the metal sheet and the gasket is designed to be automatic. A pressing block is additionally provided on the pressing seat, the bottom of the pressing block extends into the pressing seat and is in contact with the connecting end of the sliding block, and the pressing block drives the sliding blocks to move close to each other when the pressing block is pressed down. That is, the pressing block will be contacted first when the stamping device works to press down, the pressing block moves downward under the force, that is, the two sliding blocks are pushed to move close to each other, and then the two sliding blocks extending into the lower portion of the bushing metal sheet, thereby realizing the protection of the bushing metal piece. The present application realizes the clamping protection of the metal piece while starting the pressing.

[0015] In some embodiments of the present application, the bottom structure of the pressing seat is adapted to the top structure of the bushing, and the bottom surface of the pressing seat is further provided with an insertion shaft adapted to the inner hole of the bushing, the insertion shaft being in the same straight line with the shaft member; the gasket is movably connected with the sliding block, and the gasket can be up and down floating relative to the sliding block. In order to further adapt to the deflection of the metal part caused by the deformation of the rubber part during the stamping process, the gasket is designed as a floating structure. In the present application, the position of the bushing pressing head, the position of the mounting seat and the position of the calibration assembly remain consistency, so that the to-be-installed bushing can always keep coaxial with the mounting hole position on the sub-frame, and the subsequent pressing and installation can be smoothly carried out.

[0016] In some embodiments of the present application, a floating limiting shaft is further provided between the gasket and the sliding block, the floating limiting shaft being sleeved with an axial spring, the axial spring being located between the sliding block and the gasket, and the axial spring providing a force for the gasket to return to the initial state. In the present application, the gasket is elastically floating within a predetermined stroke range through the floating limiting shaft and the axial spring.

[0017] In some embodiments of the present application, the floating assembly includes an X-direction floating plate and a Y-direction floating plate, a ball is installed between the bottom surface of the Y-direction floating plate and the top surface of the X-direction floating plate, the X-direction floating plate is connected with the base through an X-direction side plate installed at the X-direction side of the X-direction floating plate, a Y-direction side plate is provided at the Y-direction side of the Y-direction floating plate, and the X-direction floating plate and the Y-direction floating plate are connected through the Y-direction side plate; the X-direction floating plate is connected with the base through two groups of X-direction springs, the X-direction springs exert X-direction force on the X-direction floating plate, and the force exertion directions of the two groups of X-direction springs are opposite; the Y-direction floating plate is connected with the X-direction floating plate through two groups of Y-direction springs, the Y-direction springs exert Y-direction force on the Y-direction floating plate, and the force exertion directions of the two groups of Y-direction springs are opposite. Through the design of the X-direction floating plate and the Y-direction floating plate, the mounting seat can be offset within a predetermined range in the horizontal plane, which is enough to solve the deviation problem of the mounting hole of the sub-frame. The setting of the ball reduces the friction force between the X-direction floating plate and the Y-direction floating plate, and the force to be overcome by the Y-direction floating plate when it moves relative to the X-direction floating plate is smaller.

[0018] Further, the spring force value of the Y-direction spring when it is in the idle state is greater than the product of the weight of the mounting seat, the friction coefficient and the guiding friction force, and the spring force value of the Y-direction spring when it is in the working state is smaller than the guiding force of the sub-frame installation. The spring force value of the X-direction spring when it is in the idle state is greater than the product of the weight of the mounting seat, the friction coefficient and the guiding friction force, and the spring force value of the X-direction spring when it is in the working state is smaller than the guiding force of the sub-frame installation. This is the preferred structure obtained by the present application in the design. If the working spring force value of the Y-direction spring and the X-direction spring is too large, it is difficult to install the mounting hole of the sub-frame on the floating seat. If the idle spring force value of the Y-direction spring and the X-direction spring is too small, it is difficult to return the spring after use.

[0019] In some embodiments of the present application, the rotating platform is provided with two left and right pressing components and four floating seats matching the mounting holes of the sub-frame, and the rotating platform is provided with two stamping devices outside; the sub-frame and the bushing are installed on the rotating platform in advance, and then the floating seats on the rotating platform are moved to below the stamping devices by the servo motor, and the stamping devices work to realize the pressing of the bushing into the sub-frame.

[0042] When the mounting seat 12 moves to the lower side of the stamping device 3, the stamping device 3 moves downward to act on the bushing pressing head, and then the guide cylinder 7 drives the guide block 8 to move downward along with the bushing pressing head. The bushing pressing head cooperates with the stamping device 3 to realize the pressing and mounting of the bushing 01 in the application.
