Description

Technical Field

[0001] The invention relates to the technical field of automobile parts assembly, in particular to a press-fitting device for an automobile shock absorber guide. Background Art

[0002] The guide is a precision component inside the shock absorber, usually located at the top of the oil cylinder or the entry and exit position of the piston rod. It is used to support and guide the movement trajectory of the piston rod to prevent the piston rod from being offset or bent due to lateral force. It also works with the oil seal to prevent oil leakage and dust and moisture intrusion, forming a double protection. In the utility model patent with application number CN202321631628.2, a "type of automobile shock absorber guide press-fitting equipment" is proposed. It can position the guide body and the guide sleeve press-fitting part respectively through the main part positioning assembly and the press-fitting part positioning assembly, so that the guide body and the guide sleeve press-fitting part can be accurately aligned along the vertical center axis, replacing the manual alignment of the guide body and the guide sleeve press-fitting part, which is conducive to improving processing efficiency. However, in this type of press-fitting equipment, the guide and the shock absorber main shaft rely on rigid positioning, and the rigid press-fitting process does not have a compensation and correction mechanism, which makes it difficult to compensate for the manufacturing tolerances between the guide and the shock absorber main shaft. During the press-fitting process, the instantaneous hard contact between the guide and the main shaft is prone to produce instantaneous high impact loads, resulting in assembly contact stress concentration, causing surface microcracks, plastic deformation or material peeling of the shock absorber main body, aggravating fatigue damage and increasing the risk factor during use.

[0042] The embodiment of the present invention provides a vehicle shock absorber guide press-fitting device, see Figure 1 , including a bracket 1, a power member 2 connected to the upper part of the bracket 1 for press-fitting the guide 5, a shock absorber fixing seat 3 located below the bracket 1, a driving member 9, an assembly adjustment member 4 arranged below the power member 2, and an assembly introduction sleeve 6 arranged below the assembly adjustment member 4. Among them, the tail of the shock absorber main body is fixed on the shock absorber fixing seat 3, and the guide 5 is initially placed on the assembly adjustment member 4; the power member 2 is a hydraulic cylinder 21 or an electric cylinder, the telescopic end of the hydraulic cylinder 21 is coaxial with the assembly introduction sleeve 6, and outputs power to press and install the guide 5, and its end is fixedly connected with a rubber pressure block 22 to avoid damaging the surface of the guide 5 during press-fitting; the assembly introduction sleeve 6 is sleeved on the upper end of the shock absorber, and the driving member 9 drives the assembly adjustment member 4 to move to the upper part of the assembly introduction sleeve 6, and the assembly adjustment member 4 and the assembly introduction sleeve 6 are pressed and positioned, and the power member 2 presses the guide 5 on the shock absorber main body.

[0043] in, Figure 2-4 , Figure 6 , Figure 7 The specific structure of the assembly positioning member 4 is shown in the figure. The assembly positioning member 4 includes an annular housing 43, a first positioning ring 41, and a second positioning ring 42. The annular housing 43 is connected to the driving member 9 and is driven by the driving member 9 to move along its axial direction. The first positioning ring 41 is arranged in the annular housing 43, and the second positioning ring 42 is arranged between the annular housing 43 and the first positioning ring 41. The first positioning ring 41 is used to pre-support the guide 5. When the annular housing 43 is driven by the driving member 9 to move above the assembly introduction sleeve 6, the first positioning ring 41 moves accordingly to cooperate with the assembly introduction sleeve 6, and at the same time, the guide 5 reaches the installation preparation position.

[0044] The first positioning ring 41 can move horizontally along the first direction DR1 relative to the second positioning ring 42, and the second positioning ring 42 can move horizontally along the second direction DR2 relative to the annular shell 43, and the first direction DR1 is perpendicular to the second direction DR2, so that the position of the guide 5 can be corrected by a certain displacement in the horizontal first direction DR1 and the second direction DR2; an inner chamfer is pre-opened at the end of the guide 5 facing the shock absorber, so that when the guide 5 is pressed into the main part of the shock absorber, it can have a small correction displacement in the horizontal direction, compensate for the compensating manufacturing tolerance and centering offset of the guide 5 and the main part of the shock absorber, and prevent rigid contact damage caused by assembly offset.

[0045] According to the embodiment of the present invention, the lower end of the annular housing 43 has a carrying ring 433 formed by bending inward, and the annular housing 43 includes a lower housing 431 and a cover plate 432 fixed to the lower housing 431 by bolts. The first positioning ring 41 and the second positioning ring 42 are restricted in displacement in the axial direction by the carrying ring 433 and the cover plate 432, thereby ensuring the stability of the first positioning ring 41 and the second positioning ring 42.

[0046] Figure 2-Figure 4 The specific structure and positional relationship of the first positioning ring 41 and the second positioning ring 42 are shown. The first positioning ring 41 includes a first upper ring body 411 and a first lower ring body 412 connected below the first upper ring body 411; the second positioning ring 42 includes a second upper ring body 421 and a second lower ring body 422 connected below the second upper ring body 421, wherein the outer diameter of the first upper ring body 411 is greater than the first lower ring body 412, the outer diameter of the second upper ring body 421 is greater than the second lower ring body 422, the first upper ring body 411 extends above the second upper ring body 421, the second upper ring body 421 extends above the carrier ring 433, the first lower ring body 412 is looped inside the second lower ring body 422, and the second lower ring body 422 is looped inside the carrier ring 433;

[0047] Two parallel second slide grooves 4331 are provided on both sides of the upper surface of the carrying ring 433; two parallel first sliders 4111 are fixed on both sides of the lower surface of the first upper ring body 411; two parallel first slide grooves 4211 are provided on both sides of the upper surface of the second upper ring body 421, and two parallel second sliders 4212 are fixed on both sides of the lower surface, the first slider 4111 is slidably connected to the first slide groove 4211 and can slide in the first slide groove 4211 along the first direction DR1, the second slider 4212 is slidably connected to the second slide groove 4331 and can slide in the second slide groove 4331 along the second direction DR2. The sliding displacement of the first slider 4111 in the first slide groove 4211 and the sliding displacement of the second slider 4212 in the second slide groove 4331 are respectively the maximum correctable displacements of the guide 5 in the first direction DR1 and the second direction DR2, and the correctable displacements are not higher than the fitting clearance between the first positioning ring 41 and the second positioning ring 42, and the fitting clearance between the second positioning ring 42 and the annular shell 43.

[0048] According to the embodiment of the present invention, the assembly adjustment member 4 and the assembly guide sleeve 6 have a structure that cooperates with each other so that after the two are fitted together, the guide 5 can be basically aligned with the main body of the shock absorber; specifically, please refer to Figure 2 -,6, the lower edges of the outer wall surfaces of the first positioning ring 41 and the second positioning ring 42 are respectively provided with a first conical surface 41a and a second conical surface 42a; the upper end of the inner side of the assembly introduction sleeve 6 is provided with a third conical surface 6a with a slope equal to and matched with the first conical surface 41a, and a fourth conical surface 6b with a slope equal to and matched with the second conical surface 42a; the gap between the first conical surface 41a and the third conical surface 6a is matched, and the gap between the second conical surface 42a and the fourth conical surface 6b is matched, and the radial displacement of the gaps of the two groups of gaps is 2%-5% of the outer diameter of the guide 5; when the driving member 9 drives the annular shell 43 to move to fit with the assembly introduction sleeve 6, the first conical surface 41a of the first positioning ring 41 extends into the inside of the third conical surface 6a, and the second conical surface 42a of the second positioning ring 42 extends into the inside of the fourth conical surface 6b. Through the guiding action of the third cone 6a and the fourth cone 6b, the guide 5 is controlled to be basically centered. At the same time, due to the clearance fit, the guide 5 can achieve adaptive fine-tuning, thereby eliminating the eccentricity error caused by manufacturing tolerance or assembly stress. Cone group A (the first and third cones 6a) and cone group B (the second and fourth cones 6b) are used as positioning references in the first direction DR1 and the second direction DR2, respectively, so that the double cones of the centering structure are redundantly constrained. The assembly adjustment member 4 can automatically compensate for the radial offset of the guide 5 by 0.03-1.2mm, so that the coaxiality error between the central axis of the guide 5 and the main axis of the shock absorber is within the standard range, while keeping the contact stress not exceeding the yield strength of the material to prevent rigid contact damage caused by assembly offset.

[0049] According to an embodiment of the present invention, the first conical surface 41a is lower than the second conical surface 42a, the inclination angle of the first conical surface 41a is smaller than that of the second conical surface 42a, and the cone angle is controlled at 15°±5°. The first conical surface 41a is preferentially engaged with the third conical surface 6a, and the high guiding accuracy of the small-angle conical surface is utilized for preliminary alignment. The small-angle conical surface has a larger contact area and can withstand higher radial offset forces, thereby avoiding jamming due to excessive eccentricity during initial assembly. The second conical surface 42a is engaged with the fourth conical surface 6b, and the large-angle conical surface is utilized for rapid convergence and alignment to eliminate residual eccentricity.

[0050] In addition, a limiting ring 415 located above the first conical surface 41a is fixed on the outside of the first positioning ring 41, and a step surface 6c is provided between the third conical surface 6a and the fourth conical surface 6b. When the limiting ring 415 abuts against the step surface 6c, a rigid stop is formed to limit the continued axial movement of the assembly positioning member 4 relative to the assembly introduction sleeve 6, thereby avoiding the interference fit of the conical surface (which may cause rupture or jamming) caused by excessive compression of the driving member 9. At the same time, the height design of the step surface 6c ensures that the first conical surface 41a and the second conical surface 42a still retain radial movement clearance after compression, thereby maintaining the adaptive positioning capability.

[0051] According to an embodiment of the present invention, a plurality of through grooves 4121 are evenly arranged around the circumference of the outer side of the first lower ring body 412, and a support plate 413 is rotatably connected to the lower side of the first upper ring body 411, and an end of the support plate 413 passes through the through groove 4121 and extends into the inner side of the first lower ring body 412, and a compression spring 414 is fixedly connected between the inner bottom of the through groove 4121 and the bottom surface of the support plate 413; the guide 5 is temporarily supported on the support plate 413, and when the guide 5 is pressurized, the support plate 413 can be pressed and rotated so that its end enters the through groove 4121, and after the two sets of conical surface matching structures are basically aligned, the guide 5 is press-fitted through the driving member 9, and radial offset correction can be performed in the assembly adjustment member 4, and the press-fitting can be performed accurately to avoid rigid contact damage.

[0052] A slide rail 7 and a transverse cylinder 8 are fixed above the bottom of the bracket 1, the shock absorber fixing seat 3 is slidably connected to the top of the slide rail 7, the transverse cylinder 8 is fixedly connected to the bottom of the shock absorber fixing seat 3, and the end of the piston rod of the transverse cylinder 8 is hard-connected to the bottom of the shock absorber fixing seat 3 by a flange. Through pneumatic control, the transverse cylinder 8 drives the shock absorber fixing seat 3 to perform horizontal reciprocating motion along the slide rail 7, realizing the precise in / out operation of the shock absorber assembly under the assembly station, and completing the rapid replacement process of different shock absorber modules.

[0053] According to the embodiment of the present invention, symmetrically arranged guide columns 31 are fixed on both sides of the upper side of the shock absorber fixing seat 3, a fixing plate 32 is slidably connected to the guide columns 31, the middle part of the fixing plate 32 is fixedly connected to the assembly guide sleeve 6, a spring 33 is sleeved on the outer side of the guide columns 31, the lower end of the spring 33 abuts against the lower side of the fixing plate 32, and a limit block 34 for limiting the highest position of the fixing plate 32 is fixed on the upper side of the guide columns 31. When the assembly adjustment member 4 is driven by the driving member 9 and pressed and matched with the assembly guide sleeve 6, the design of the spring 33 provides elastic buffering, allowing the assembly guide sleeve 6 to move downward for a distance, generating a controllable displacement, and avoiding excessive contact stress between the assembly adjustment member 4 and the assembly guide sleeve 6; at the same time, when the shock absorber is pressed and the support plate 413 is pushed open, the assembly guide sleeve 6 can also move slightly downward to weaken part of the impact load, avoiding the guide 5 and the shock absorber body from rigid contact assembly damage.

[0054] The driving member 9 is two oppositely arranged linear modules fixedly connected to the two sides of the bracket 1. The two sides of the annular shell 43 are fixedly connected to the slide seat of the linear module. The linear module drives the annular shell 43 to move and press the assembly adjustment member 4 and the assembly guide sleeve 6 into a tight fit.
