Description

TECHNICAL FIELD

[0001] The application relates to the production and processing technical field of automobile parts, in particular to a shock absorber press. BACKGROUND

[0002] In the modern automobile industry, shock absorbers play a crucial role. The main function of a shock absorber is to suppress the vibrations and jolts caused by road bumps, braking, acceleration, etc. during the driving process, thereby ensuring the driving stability, comfort and handling performance of the vehicle. The automobile shock absorber is usually installed in the suspension system of the vehicle, which absorbs and buffers the vibration energy through the internal mechanical structure and hydraulic system, thereby reducing the impact of the jolts and vibrations on the vehicle body and parts.

[0003] In the production and processing of shock absorbers, a press is involved, which is used to press and assemble various parts. Related prior art such as Chinese patent application "Shock absorber press", application number: CN201410388891.2, discloses a shock absorber press comprising: a shock absorber positioning and changing mechanism, an upper centering mechanism, a servo press assembly mechanism, an automatic tightening mechanism, an elbow press mechanism, a servo positioning mechanism, a rack, a control system; the shock absorber positioning and changing mechanism is used to correspond to different types of shock absorbers; the upper centering mechanism is used to center the shock absorber cap after the shock absorber positioning and changing mechanism fixes the shock absorber column, so that the axis of the shock absorber column and the shock absorber cap hole remain concentric; the servo press assembly mechanism is used to determine the press assembly height according to the type of the shock absorber column, and then press assembles the spring nested on the shock absorber column; the elbow press mechanism is used to press the shock absorber column to keep the position unchanged during the press assembly of the spring; the servo positioning mechanism is used to adjust the height of the upper centering mechanism according to the type of the shock absorber column; the automatic tightening mechanism is used to select the corresponding torque according to the type of the shock absorber column, and the torque is controlled by servo to screw the nut into the shock absorber column; the control system is used to control the movement of each part of the shock absorber press; the rack is used to install each part of the shock absorber press.

[0004] The pressure of the common press is applied from the top, and the reaction force is provided by the bottom workbench of the press. The bottom workbench must be very stable and can withstand the entire press assembly reaction force without deformation or displacement. The rigidity requirement of the entire device is concentrated on the support structure. For example, Figure 1As shown, the semi-finished shock absorber to be press-fitted in this application includes a main body, a base and a side shell. After the main body and the base are press-fitted into shape, the side shell is press-fitted from one side. During the entire process, the pressing force required to press-fit the main body and the base is relatively large, which requires the press to have a sufficiently large output force, and at the same time requires the bottom workbench to be able to withstand a pressure of nearly one ton, so as to ensure the stability and accuracy of the pressing process. If a simple mechanical structure is used, a large and heavy frame structure will be required. This structure not only makes the equipment itself bulky, but also requires it to occupy a large space when arranged in the workshop, which is not conducive to the space utilization of the factory and the flexibility of the equipment layout. Summary of the Invention

[0005] The technical problem to be solved by the present application is to provide a shock absorber press, which improves the stability and precision of press-fitting, reduces the requirements for the bottom support structure, and at the same time optimizes the equipment structure and improves space utilization.

[0006] The technical solution adopted in this application is: a shock absorber press, comprising a frame, a notch is provided on the frame, a mounting seat is provided at the notch, a jacking mechanism is connected below the mounting seat, an upper die tooling is provided above the mounting seat, the upper die tooling is connected to the lower pressing mechanism, a profiling seat is provided on the left side of the mounting seat, the profiling seat is connected to the side pressure mechanism, a profiling pressure head is provided on the right side of the mounting seat, the profiling pressure head is connected to the pressure head power cylinder, the upper die tooling, the profiling pressure head and the mounting seat are located in a vertical line, the shock absorber comprises a main body, a base and a side shell, the main body is installed at the upper die tooling, the base is installed on the mounting seat, and the side shell is placed on the profiling seat, the lower pressing mechanism drives the upper die tooling to press downward, the jacking mechanism drives the mounting seat to move upward, and the side pressure mechanism drives the profiling seat to move horizontally.

[0007] Compared with the prior art, the advantages of the present application are that, first, the mounting seat is lifted from below by a lifting mechanism, and at the same time, the upper mold tooling applies pressure from above through a pressing mechanism, so that the main body and base of the shock absorber are subjected to forces in both the upper and lower directions during the press-fitting process. On the one hand, this bidirectional force balance design effectively improves the stability and reliability of press-fitting. On the other hand, this design significantly reduces the rigidity requirements for the bottom supporting structure (such as the frame or work surface), and reduces the risk of reduced press-fitting accuracy due to deformation or displacement of the bottom supporting structure. Since the press-fitting force is mainly borne by the lifting mechanism, the frame design of the press can be more lightweight, without the need for a large, heavy frame structure, thereby reducing the size of the equipment and reducing the equipment cost.

[0008] Secondly, because the press-fitting force is balanced at the top and bottom ends and laterally, the net force inside the product is close to zero, similar to being "sandwiched" in the middle. This design reduces residual stress within the product and improves its service life and reliability.

[0009] Thirdly, by reasonably arranging the jacking mechanism, the pressing-down mechanism and the side pressing mechanism, the structure of the whole press is more compact, and the floor space of the equipment is reduced. The compact design makes the equipment more flexible in workshop layout, and improves the space utilization of the factory.

[0010] In summary, the technical scheme of the damper press significantly improves the stability and precision of the pressing process, reduces the rigidity requirement and cost of the equipment, improves the universality and space utilization of the equipment, and is particularly suitable for pressing complex-shaped and easily-deformed damper parts.

The output shaft of the side power cylinder penetrates through the mounting base and is connected with the sliding support.

[0012] By arranging the transverse sliding rails and the sliding support, the profiling seat can move horizontally along the transverse sliding rails stably and accurately, ensuring the stability and precision of the side pressing process. The side power cylinder directly drives the sliding support, the power transmission path is short, the response speed is fast, and the pressing efficiency can be improved.

[0014] The side displacement gauge can accurately measure the distance of the movement of the sliding support, that is, the distance of the movement of the profiling seat. In the present application, the first detection probe and the second detection probe are both laser ranging sensors. The side displacement gauge can accurately measure the movement distance of the profiling seat, ensuring the accuracy of the pressing position. The arrangement of the detection probes realizes automatic detection of the installation and movement position of the side shell, improves the automation degree of the press, reduces manual intervention, and improves the production efficiency and pressing quality.

The output shaft of the pressing power cylinder is connected through the fixed plate and the movable plate. The upper die tool is installed below the movable plate. The guide column assembly provides stable guidance for the up-and-down movement of the movable plate, ensuring the movement accuracy of the upper die tool. This structural design enables the pressing mechanism to apply pressure smoothly and accurately, improving the stability and reliability of the pressing process.

[0016] In some embodiments of the present application, a pressing displacement scale is arranged on the fixed plate. The reading head of the pressing displacement scale is connected to the movable plate. A third detection probe is installed on the movable plate, which is used to detect whether the main body is installed to the upper die tool. A fourth detection probe is installed on the rack and is located below the movable plate to detect whether the main body moves to the position of the fourth detection probe.

[0017] The pressing displacement scale can accurately measure the distance of the sliding support, that is, the distance of the profiling seat. In the present application, the third detection probe and the fourth detection probe are both laser ranging sensors. The pressing displacement scale can accurately measure the movement distance of the movable plate, thereby controlling the pressing position of the upper die tool and ensuring the pressing accuracy. The arrangement of the detection probes realizes automatic detection of the installation and movement position of the main body, further improving the automation degree and pressing quality of the press.

[0018] In some embodiments of the present application, a dragging frame is installed on the rack. The dragging frame has a rectangular structure and is located on the outer periphery of the slot. The dragging frame is connected to a dragging cylinder. The dragging cylinder is fixedly installed below the dragging frame. The profiling pressure head is movably installed on the dragging frame. The pressure head power cylinder drives the profiling pressure head to press down. The dragging cylinder drives the dragging frame and the profiling pressure head to move towards the main body.

[0019] The arrangement of the dragging frame and the dragging cylinder enables the profiling pressure head to move smoothly towards the main body. The profiling pressure head is inserted into the main body, ensuring the stability of the pressing process. This structural design can realize accurate alignment and pressing of the profiling pressure head, improving the pressing efficiency and quality.

[0020] In some embodiments of the present application, a limiting reference block is also fixed at the slot. One side surface of the limiting reference block is a reference surface matching one side of the base. The mounting seat has a rectangular block structure as a whole. A receiving groove matching the base is formed on the top surface of the mounting seat. An opening is arranged on one side wall surface of the receiving groove. The limiting reference block matches the opening. The mounting seat moves upward until the limiting reference block is completely embedded in the opening, which is the limit position of the stroke.

[0021] By the cooperation of the limiting reference block and the gap, the movement track and the limit position of the upward movement of the mounting seat are accurately defined, the upward and downward pressing can be fully contacted without exceeding the safe stroke, and the stability and reliability of the pressing are improved.

[0022] In some embodiments of the present application, the jacking mechanism comprises a vertically arranged mounting base plate, longitudinal sliding rails are arranged on both sides of the mounting base plate, sliding blocks are mounted on the longitudinal sliding rails, the mounting seat is divided into a left block and a right block, the left block and the right block are respectively connected above the two sliding blocks, and the left block and the right block are spliced to form the mounting seat. A reference seat is arranged below the longitudinal sliding rails, a jacking power cylinder is movably arranged on one side of the longitudinal sliding rails, the output shaft of the jacking power cylinder is hingedly connected to one end of a first connecting piece and one end of a second connecting piece, the other end of the first connecting piece is hingedly connected to the sliding block, and the other end of the second connecting piece is hingedly connected to the reference seat. This structure design enables the jacking mechanism to smoothly and accurately drive the mounting seat to move up and down. The cooperation of the longitudinal sliding rails and the sliding blocks provides stable guidance for the movement of the mounting seat, ensures the accuracy and stability of the jacking process, and reduces the requirement for the accuracy of the power cylinder.

[0023] In some embodiments of the present application, a fixed base is arranged on one side of the longitudinal sliding rail, the end of the jacking power cylinder away from the output shaft is rotatably connected to the fixed base through a rotating shaft, and the jacking power cylinder is stressed along the rotation around the rotating shaft. The output shaft of the jacking power cylinder is fixedly mounted with a main connecting piece, the main connecting piece is provided with a main hinge point, and the first connecting piece and the second connecting piece are hingedly connected to the main hinge point. The position where the first connecting piece is hingedly connected to the sliding block is recorded as a first hinge point, the position where the second connecting piece is hingedly connected to the reference seat is recorded as a second hinge point, and the first hinge point is located directly above the second hinge point. The rotatable connection design enables the jacking power cylinder to automatically adjust the angle during the working process, reduces the resistance and stress concentration in the movement process, and prolongs the service life of the power cylinder. The arrangement of the main connecting piece and the main hinge point simplifies the power transmission path, improves the efficiency and stability of power transmission.

[0024] In some embodiments of the present application, a plurality of adjusting washers are detachably arranged between the left block, the right block and the sliding blocks connected thereto.

[0025] The height of the left block and the right block is adjusted by increasing or decreasing the number of adjusting washers, so that the left block and the right block are located at the same height, thereby splicing into a flat mounting seat. This adjustable design improves the versatility and adaptability of the equipment, and can also adapt to different specifications of the shock absorber base.

[0026] In the present application, the downward pressing power cylinder and the lateral power cylinder are both electric cylinders, and the jacking power cylinder is a small air cylinder. According to the structure design of the lever principle, the power of an air cylinder of about 100 kg is lifted to bear a pressing force of about 1 ton.

[0027] In some embodiments of the present application, a main hinge opening is provided on the main hinge, and the main hinge point is located at the main hinge opening. One end of the first connecting member and one end of the second connecting member extend into the main hinge opening. The design of the main hinge opening enables the first connecting member and the second connecting member to be more closely connected with the main hinge point, thereby enhancing the firmness and stability of the connection, reducing the gap between the connecting members, and improving the accuracy and response speed of power transmission.

[0028] In some embodiments of the present application, the first connecting member has an I-shaped structure, and the second connecting member has a Y-shaped structure. One end of the second connecting member located at the main hinge opening extends into the first connecting member. The design of the I-shaped and Y-shaped structures improves the strength and stability of the connecting members, and enables them to better withstand the press-fitting force. This structural design also effectively reduces the volume and weight of the connecting members, thereby improving the compactness of the entire mechanism.

[0029] In some embodiments of the present application, two parallel longitudinal sliding rails are provided on the mounting surface, and the sliding block is movably connected with the two longitudinal sliding rails. The middle part of the sliding block is provided with a connecting strip, and the lower end of the connecting strip extends out of the sliding block. The first hinge point is located at the lower end of the connecting strip. The two parallel longitudinal sliding rails provide more stable guidance for the sliding block, ensuring that the sliding block always maintains straight-line motion during movement and reducing motion deviation. The design of the connecting strip makes the position of the first hinge point more stable, further improving the accuracy and reliability of power transmission.

[0030] In some embodiments of the present application, the main hinge point, the first hinge point, and the second hinge point form an isosceles triangle. The isosceles triangular structure enables the force distribution between the connecting members to be more uniform, thereby reducing the risk of equipment damage caused by unbalanced force. At the same time, this symmetrical structure improves the stability and reliability of the entire mechanism, ensuring the smoothness and accuracy of the jacking process.

[0031] In some embodiments of the present application, a limiting column is provided on one side of the reference seat, and the limiting column is located below the second connecting member. A buffer column is provided on the side of the reference seat facing the power cylinder, and the buffer column limits the movement limit position of the second connecting member.

[0032] The design of the limiting column can limit the movement trajectory of the second connecting member. Both the limiting column and the buffer column can prevent the second connecting member from deviating or colliding during movement, thereby improving the operational safety and stability of the entire mechanism. The limiting column and the buffer column can also act as a buffer, reducing the risk of equipment damage caused by impact.

DETAILED DESCRIPTION

[0037] The present application will be described in further detail below in conjunction with the accompanying drawings and preferred embodiments, but those skilled in the art will appreciate that the drawings are only for the purpose of explaining the preferred embodiments and thus should not be taken as limiting the scope of the present application. In addition, the drawings only schematically represent the composition or configuration of the described objects and can contain exaggerated displays, unless specifically indicated, and the drawings are not necessarily drawn to scale.

[0038] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0039] A shock absorber press, embodiment 1 Figures 1 to 2 As shown, the frame 1 includes a slot 2, a mounting seat 3 disposed at the slot 2, a lifting mechanism 4 connected below the mounting seat 3, an upper die fixture 5 disposed above the mounting seat 3, and a lower pressing mechanism 6 connected to the upper die fixture 5. The shock absorber includes a main body 11, a base 12, and a side shell 13. The main body 11 is mounted on the upper die fixture 5, the base 12 is mounted on the mounting seat 3, and the side shell 13 is placed on the contour seat 7. The lower pressing mechanism 6 drives the upper die fixture 5 downward, and the lifting mechanism 4 drives the mounting seat 3 upward. The lifting mechanism 4 lifts the mounting seat 3 from below, while the upper die fixture 5 applies pressure from above via the lower pressing mechanism 6, so that the main body 11 and base 12 of the shock absorber are subjected to forces in both the upper and lower directions during the press-fitting process. On the one hand, this bidirectional force balancing design effectively improves the stability and reliability of the press-fitting. Furthermore, this design significantly reduces the rigidity requirements for the underlying support structure (e.g., frame 1 or work surface), minimizing the risk of reduced press-fitting accuracy due to deformation or displacement of the underlying support structure. Because the press-fitting force is primarily borne by the jacking mechanism 4, the press frame 1 can be designed to be even lighter, eliminating the need for a large, heavy frame structure. This reduces the size of the machine and lowers its cost.

[0040] Because the press-fitting force is balanced at the top and bottom of the product and laterally, the net force within the product is close to zero, similar to being "sandwiched" in the middle. This design reduces residual stress within the product, improving its service life and reliability. The rational layout of the lifting mechanism 4, the pressing mechanism 6, and the side-pressing mechanism 8 makes the entire press structure more compact, reducing the equipment's footprint. This compact design allows for greater flexibility in workshop layout and improves factory space utilization.

[0041] The left side of the mounting base 3 is provided with a profiling seat 7, which is connected to a side pressure mechanism 8.

The technical solution of the shock absorber press machine of the present application significantly improves the stability and accuracy of the press-fitting process through multi-directional collaborative press-fitting, a closed-loop force design, and a compact structural layout, reduces the rigidity requirements and cost of the equipment, and improves the versatility and space utilization of the equipment. It is particularly suitable for press-fitting of complex-shaped and easily deformed shock absorber parts.

Through the arrangement of the transverse sliding rails 17 and the sliding bracket 16, the profiling seat 7 can stably and accurately move horizontally along the transverse sliding rails 17, so as to ensure the stability and accuracy of the side pressing process. The side power cylinder 14 directly drives the sliding bracket 16, the power transmission path is short, the response speed is fast, and the pressing efficiency can be improved.

The side displacement ruler 18 can accurately measure the distance moved by the sliding bracket 16, that is, the distance moved by the profiling seat 7. In this application, the first detection probe 19 and the second detection probe 20 are both laser ranging sensors. The side displacement ruler 18 can accurately measure the moving distance of the profiling seat 7, so as to ensure the accuracy of the pressing position. The arrangement of the detection probes realizes automatic detection of the installation and moving positions of the side shell 13, improves the automation degree of the pressing machine, reduces manual intervention, and improves the production efficiency and pressing quality.

The downward displacement ruler 25 can accurately measure the distance moved by the sliding bracket 16, that is, the distance moved by the contour seat 7. In this application, the third detection probe 26 and the fourth detection probe 27 both use laser ranging sensors. The downward displacement ruler 25 can accurately measure the moving distance of the movable plate 23, thereby controlling the downward position of the upper mold tooling 5 and ensuring the press-fitting accuracy.

The height of the left block 3a and the right block 3b is adjusted by increasing or decreasing the number of adjusting shims 48, so that the left block 3a and the right block 3b are located at the same height, and then spliced into a flat mounting seat 3. The adjustable design improves the universality and adaptability of the equipment, and can also adapt to different specifications of the shock absorber base 12.

[0053] In the present application, the downward pressing power cylinder 21 and the lateral power cylinder 14 are both electric cylinders, and the jacking power cylinder 40 is a small air cylinder.

[0054] The main hinge point 45 is located at the main hinge interface 49, and one end of the first connecting piece 41 and one end of the second connecting piece 42 extend into the main hinge interface 49. The design of the main hinge interface 49 enables the first connecting piece 41 and the second connecting piece 42 to be more closely connected with the main hinge point 45, thereby enhancing the firmness and stability of the connection, reducing the gap between the connecting pieces, and improving the accuracy and response speed of power transmission.

[0055] The first connecting piece 41 has an I-shaped structure, and the second connecting piece 42 has a Y-shaped structure. One end of the second connecting piece 42 located at the main hinge interface 49 extends into the first connecting piece 41. The I-shaped and Y-shaped structures improve the strength and stability of the connecting pieces and enable them to better withstand the pressure assembly force. Such a structure design can also effectively reduce the volume and weight of the connecting pieces and improve the compactness of the entire mechanism.

[0056] Two longitudinally arranged longitudinal sliding rails 35 are arranged on the mounting surface, and the sliding block 36 is movably connected with the two longitudinally arranged longitudinal sliding rails 35. The middle part of the sliding block 36 is provided with a connecting strip 50, the lower end of the connecting strip 50 extends out of the sliding block 36, and the first hinge point 46 is located at the lower end of the connecting strip 50. The two longitudinally arranged longitudinal sliding rails 35 provide more stable guidance for the sliding block 36, ensuring that the sliding block 36 always maintains linear motion during movement and reducing movement deviation. The design of the connecting strip 50 makes the position of the first hinge point 46 more stable, further improving the accuracy and reliability of power transmission.

[0057] The main hinge point 45, the first hinge point 46, and the second hinge point 47 form an isosceles triangle. The isosceles triangular structure enables the force distribution between the connecting pieces to be more uniform, reducing the risk of equipment damage caused by unbalanced force. At the same time, such a symmetrical structure can improve the stability and reliability of the entire mechanism, ensuring the smoothness and accuracy of the jacking process.

[0058] A limiting column 51 is arranged on one side of the reference seat 39, and the limiting column 51 is located below the second connecting piece 42. A buffer column 52 is arranged on the side of the reference seat 39 facing the power cylinder, and the buffer column 52 limits the movement limit position of the second connecting piece 42. The design of the limiting column 51 can limit the movement trajectory of the second connecting piece 42, and both the limiting column 51 and the buffer column 52 can prevent the second connecting piece 42 from deviating or colliding during movement, thereby improving the operation safety and stability of the entire mechanism. The limiting column 51 and the buffer column 52 can also act as a buffer, reducing the risk of equipment damage caused by impact.

[0059] The other contents of Example Three are the same as those of Example One or Example Two.

The above description of the examples is only used to help understand the application and the core idea. It should be pointed out that, for ordinary skilled persons in the technical field, some improvements and modifications can be made to the application without departing from the principles of the application, and these improvements and modifications also fall within the protection scope of the claims of the application.
