Description

Technical Field

[0001] The present application relates to the technical field of automobile bushing press-fitting, and in particular to a camber arm bushing press-fitting device. Background Art

[0002] The chassis of a car has always been a key factor that consumers pay attention to when buying a car. Different car suspensions give people completely different driving feelings. Whether the car can be guaranteed to be able to drive smoothly on bumpy roads is closely related to a very important structure in the suspension - the "subframe". The subframe is divided into two types: front and rear. Before the birth of the subframe, the suspension rocker mechanism of the front and rear axles of the traditional load-bearing body was a loose part, and the suspension was directly connected to the body; after the birth of the subframe, the front and rear suspensions can be assembled on the subframe to form an axle assembly, and then rigidly or flexibly connected to the car body.

[0003] The early assembly process generally involved manually clamping the bushings, accurately preloading them on the frame, and then press-fitting them using a press. This was labor-intensive, with low production efficiency, and it was difficult to ensure consistent press-fitting results, which could not meet current automated production requirements.

[0004] Automated press-fitting equipment also appeared on the market later, such as the Chinese patent application "Automatic press-fitting device for frame bushings", application number: CN202311768561.1; it discloses a base, a frame positioning assembly, a bushing positioning assembly and a press-fitting assembly, wherein the frame positioning assembly is arranged on the base, used to fix the frame workpiece to be assembled, and the frame workpiece is provided with a bushing mounting hole; the bushing positioning assembly is arranged on the base, used to load and position the bushing workpiece to be assembled, including a positioning head extending into the bushing mounting hole, and the bushing workpiece is placed on the positioning head; the press-fitting assembly includes a bushing pressing head coaxially arranged with the positioning head, and the bushing pressing head is used to press the bushing workpiece, so that the bushing workpiece and the frame workpiece are assembled in place. The present invention realizes accurate positioning and reliable press-fitting of the bushing workpiece and the frame workpiece, and can realize a fully automated production process in conjunction with a manipulator, etc., which reduces the difficulty of manual press-fitting of bushings, reduces labor input, and improves production efficiency and processing quality.

[0005] However, the frame structure involved in this application is as follows Figure 1 As shown in the figure, after the frame is installed on the fixture, there are two horizontal mounting holes on the upper part that need to be equipped with bushings. Obviously, the mounting holes at this position cannot be installed by a vertically arranged press-fit device. Even if the entire frame is placed vertically, there are still many interferences in the structure of the frame itself. Utility Model Content

[0006] The technical problem to be solved by the present application is to provide a camber arm pressing sleeve device, design a horizontal pressing sleeve assembly, and hoist it through a gantry and a lifting mechanism. The lifting mechanism drives the pressing sleeve assembly to move to a suitable bushing pressing position to achieve the pressing of the horizontal horizontal mounting hole.

[0007] The technical solution adopted in the present application is: a camber arm pressing sleeve device, including a gantry, a crossbeam is arranged in the middle of the gantry, a vertical slide rail is installed on the crossbeam in cooperation with the gantry, a slide seat connected to a power cylinder is movably installed on the vertical slide rail, at least one pressing sleeve assembly is hoisted under the slide seat, the pressing sleeve assembly is arranged horizontally, the pressing sleeve assembly includes a bottom support and a pressure head arranged opposite to the bottom support, and there is a spacing between the bottom support and the pressure head for the frame part to extend into.

[0008] Compared with the prior art, the advantage of the present application is that a gantry is provided, and the pressing sleeve assembly is suspended by the gantry, so that the conventional vertically placed pressing sleeve assembly (i.e., the direction of the pressing drive working is the vertical direction) is changed to a horizontal setting (i.e., the direction of the pressing drive working is the horizontal direction). Then, when the pressing sleeve assembly is connected to the slide, the angle of the pressing sleeve assembly is pre-adjusted, so when the power cylinder drives the slide to move downward, the pressing sleeve assembly can be relative to the mounting hole of the frame to be pressed at a suitable angle. Specifically, there is a gap between the base support of the pressing sleeve assembly and the pressing head for part of the frame to extend into. When the bushing to be pressed and the mounting hole of the frame extend into the gap between the base support and the pressing head, the pressing head moves toward the base support to realize the pressing of the bushing.

[0009] In some embodiments of the present application, at least one pressing sleeve assembly is hoisted under the slide seat, the two pressing sleeve assemblies are symmetrically arranged on the left and right, and the angle between the two pressing sleeve assemblies is an acute angle.

[0010] In the present application, the specific number of pressing sleeve assemblies and the angle of the pressing sleeve assemblies are determined by the number and angle of the mounting holes of the vehicle frame to be pressed.

[0011] In some embodiments of the present application, a conveying track and a pallet installed on the conveying track are further included, the pallet is provided with a fixing tool for fixing the frame, the conveying track is provided with a press-fitting position, and the slide works when the pallet moves to the press-fitting position.

[0012] In some embodiments of the present application, a control device and a sensor are provided on the pallet, the sensor is connected to the control device, the control device is electrically connected to the power cylinder, the sensor senses whether the pallet has moved to the pressing position and sends a signal to the control device, and the control device controls the operation of the power cylinder according to the signal.

[0013] The above is a design idea for realizing automation of the present application, in which a sensor is used to detect whether the pallet has moved into place, and a control device is used to realize signal transmission and start the work.

[0014] In some embodiments of the present application, a mounting seat is provided in the middle of the support plate, a pressing seat is installed on the mounting seat, a positioning pin is provided on the pressing seat, the positioning pin is coaxial with the frame mounting hole to be pressed, and the bushing is sleeved outside the positioning pin. In the present application, the installation and positioning of the bushing is achieved by providing a mounting seat in the middle of the support plate.

[0015] In some embodiments of the present application, a horizontal slide rail is provided on the support plate, and the mounting seat is installed on the horizontal slide rail. The mounting seat moves along the horizontal slide rail when subjected to force, and the horizontal slide rail is parallel to the axial direction of the frame mounting hole to be pressed.

[0016] In some embodiments of the present application, the pressing sleeve assembly includes a power device, and the power device is connected to the bottom bracket to drive the bottom bracket to move and change the distance between the bottom bracket and the pressing head. In the present application, the distance between the bottom bracket and the pressing head can be changed according to the structure of the part to be pressed, so that the bottom bracket can be extended into the frame.

[0017] In some embodiments of the present application, the bottom bracket moved down to the frame is in contact with the mounting seat, and the power device drives the mounting seat to move toward the side of the frame mounting hole to be pressed through the bottom bracket, and the moving mounting seat presses the bushing into the frame mounting hole. In the present application, because the mounting seat for installing the bushing is pre-installed and the mounting seat is movable, the sleeve pressing assembly in the present application mainly plays the role of a pressing driving force to drive the mounting seat to move.

[0018] In some embodiments of the present application, the pressing head that moves down to the frame is located on the outside of the frame, and the pressing head is opposite to the mounting hole of the frame to be press-installed.

[0019] In some embodiments of the present application, the pressing head is connected to an electric cylinder, and the electric cylinder drives the pressing head to move axially along the frame mounting hole to be pressed; when the bushing is pressed, the pressing head moves to contact and connect with the frame mounting hole to be pressed. In the present application, the pressing head mainly plays the role of providing support force at the frame mounting hole to prevent the frame from being deformed by force during the pressing process.

[0020] The above-mentioned implementation modes can be combined arbitrarily based on the common knowledge in the art. BRIEF DESCRIPTION OF THE DRAWINGS
