Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile parts assembly, in particular to an automobile shock absorber guide press-fitting equipment. BACKGROUND

[0002] The guide is a precise component inside the shock absorber, usually located at the top of the oil cylinder or the inlet and outlet position of the piston rod, used to support and guide the movement trajectory of the piston rod, prevent the piston rod from deviating or bending due to lateral force, and work with the oil seal to prevent oil leakage and dust and moisture intrusion, forming double protection. In the utility model patent with application number CN202321631628.2, an "automobile shock absorber guide press-fitting equipment" is proposed, which can position the guide body and the guide sleeve press-fitting part 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 central axis, replacing the manual alignment of the guide body and the guide sleeve press-fitting part, which is beneficial to improve the 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 is installed, which does not have a compensation and correction mechanism. This is difficult to compensate for the manufacturing tolerance 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 easy to produce instantaneous high impact load, which causes the assembly contact stress to concentrate, causing surface micro-cracks, plastic deformation or material peeling of the shock absorber main part, aggravating fatigue damage and increasing the risk coefficient in use.

[0042] An embodiment of the present invention provides a press-fitting device for automotive shock absorber guides. Please refer to [link / reference]. Figure 1 The assembly includes a bracket 1, a power component 2 connected above the bracket 1 for pressing the guide 5, a shock absorber mounting base 3 located below the bracket 1, a drive component 9, an assembly adjustment component 4 located below the power component 2, and an assembly guide sleeve 6 located below the assembly adjustment component 4. The tail of the shock absorber body is fixed to the shock absorber mounting base 3, and the guide 5 is initially placed on the assembly adjustment component 4. The power component 2 is a hydraulic cylinder 21 or an electric cylinder. The extension end of the hydraulic cylinder 21 is coaxial with the assembly guide sleeve 6, outputting power to press and install the guide 5. A rubber pressure block 22 is fixedly connected to its end to prevent damage to the surface of the guide 5 during pressing. The assembly guide sleeve 6 is fitted onto the upper end of the shock absorber. The drive component 9 moves the assembly adjustment component 4 above the assembly guide sleeve 6, where the assembly adjustment component 4 and the assembly guide sleeve 6 are pressed together for positioning. The power component 2 presses the guide 5 onto the shock absorber body.

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

[0044] The first adjusting ring 41 can move horizontally relative to the second adjusting ring 42 along the first direction DR1, and the second adjusting ring 42 can move horizontally relative to the annular housing 43 along the second direction DR2. The first direction DR1 and the second direction DR2 are perpendicular, which allows the position of the guide 5 to be corrected by a certain displacement in the horizontal first direction DR1 and the second direction DR2. An inner chamfer is pre-cut at the end of the guide 5 facing the shock absorber so that the guide 5 can have a small amount of correction displacement in the horizontal direction when it is press-fitted into the main body of the shock absorber. This compensates for the manufacturing tolerance and centering offset of the guide 5 and the main body of the shock absorber, and prevents rigid contact damage caused by assembly offset.

[0045] According to an embodiment of the present invention, the lower end of the annular housing 43 has an inwardly bent mounting ring 433. The annular housing 43 includes a lower housing 431 and a cover plate 432 fixed to the lower housing 431 by bolts. The first adjusting ring 41 and the second adjusting ring 42 are axially restricted in displacement by the mounting ring 433 and the cover plate 432 to ensure the stability of the first adjusting ring 41 and the second adjusting ring 42.

[0046] Figures 2-4 The specific structure and positional relationship of the first adjusting ring 41 and the second adjusting ring 42 are shown. The first adjusting 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 adjusting ring 42 includes a second upper ring body 421 and a second lower ring body 422 connected below the second upper ring body 421. The outer diameter of the first upper ring body 411 is larger than that of the first lower ring body 412, and the outer diameter of the second upper ring body 421 is larger than that of the second lower ring body 422. The first upper ring body 411 extends above the second upper ring body 421, and the second upper ring body 421 extends above the mounting ring 433. The first lower ring body 412 is enclosed within the second lower ring body 422, and the second lower ring body 422 is enclosed within the mounting ring 433.

[0047] Two parallel second sliding grooves 4331 are provided on both sides of the upper surface of the mounting 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 sliding 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 sliders 4111 are slidably connected to the first sliding grooves 4211 and can slide in the first sliding grooves 4211 along the first direction DR1. The second sliders 4212 are slidably connected to the second sliding grooves 4331 and can slide in the second sliding grooves 4331 along the second direction DR2. The sliding displacement of the first slider 4111 in the first groove 4211 and the sliding displacement of the second slider 4212 in the second groove 4331 are respectively the maximum corrective displacement of the guide 5 in the first direction DR1 and the second direction DR2. The corrective displacement is not higher than the fit gap between the first adjusting ring 41 and the second adjusting ring 42, and the fit gap between the second adjusting ring 42 and the annular shell 43.

[0048] According to an embodiment of the present invention, the assembly adjusting component 4 and the assembly guide sleeve 6 have a mutually cooperating structure so that after they are fitted together, the guide 5 can be substantially aligned with the main body of the shock absorber; specifically, please refer to Figure 2 -,6, The lower edges of the outer walls of the first adjusting ring 41 and the second adjusting ring 42 are respectively provided with a first conical surface 41a and a second conical surface 42a; the upper inner side of the assembly guide sleeve 6 is provided with a third conical surface 6a that has the same slope as the first conical surface 41a and a fourth conical surface 6b that has the same slope as the second conical surface 42a and a matching surface; there is a clearance fit between the first conical surface 41a and the third conical surface 6a, and a clearance fit between the second conical surface 42a and the fourth conical surface 6b, and the radial displacement of the clearance fit between the two sets of clearance fits is 2%-5% of the outer diameter of the guide 5; when the driving member 9 drives the annular housing 43 to move to fit with the assembly guide sleeve 6, the first conical surface 41a of the first adjusting ring 41 extends into the interior of the third conical surface 6a, and the second conical surface 42a of the second adjusting ring 42 extends into the interior of the fourth conical surface 6b. The guide surface 5 is basically aligned by the guiding action of the third conical surface 6a and the fourth conical surface 6b. Simultaneously, due to the clearance fit, the guide surface 5 can achieve adaptive fine-tuning, thereby eliminating eccentricity errors caused by manufacturing tolerances or assembly stress. Conical surface group A (first and third conical surfaces 6a) and conical surface group B (second and fourth conical surfaces 6b) serve as positioning references in the first direction DR1 and the second direction DR2, respectively, providing redundant constraints on the double conical surfaces of the alignment structure. The assembly adjustment component 4 can automatically compensate for the radial offset of the guide surface 5 by 0.03-1.2mm, ensuring that the coaxiality error between the central axis of the guide surface 5 and the main shaft of the shock absorber is within the standard range, while maintaining the contact stress below the material yield strength, preventing rigid contact damage caused by assembly misalignment.

[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 conical surface angle is controlled at 15°±5°. The first conical surface 41a preferentially engages with the third conical surface 6a, and the high guiding accuracy of the small-angle conical surface is used for initial alignment. Moreover, the small-angle conical surface has a larger contact area and can withstand higher radial offset force, avoiding jamming due to excessive eccentricity during initial assembly. The second conical surface 42a engages with the fourth conical surface 6b, and the large-angle conical surface is used to quickly converge and align, eliminating residual eccentricity.

[0050] In addition, a limiting ring 415 is fixed on the outside of the first adjusting ring 41, located above the first conical surface 41a. A stepped surface 6c is provided between the third conical surface 6a and the fourth conical surface 6b. When the limiting ring 415 abuts against the stepped surface 6c, it forms a rigid stop, restricting the assembly adjusting component 4 from continuing to move axially relative to the assembly guide sleeve 6, thus avoiding excessive pressing of the driving component 9 that could lead to an interference fit of the conical surface (potentially causing cracking or jamming). At the same time, the height design of the stepped surface 6c ensures that the first conical surface 41a and the second conical surface 42a retain radial movement clearance after pressing, maintaining self-adjusting capability.

[0051] According to an embodiment of the present invention, a plurality of through grooves 4121 are uniformly opened around the outer side of the first lower ring body 412. A support plate 413 is rotatably connected below the first upper ring body 411. The end of the support plate 413 passes through the through grooves 4121 and extends into the inner side of the first lower ring body 412. A compression spring 414 is fixedly connected between the bottom of the through grooves 4121 and the bottom surface of the support plate 413. The guide 5 is temporarily supported on the support plate 413. When the guide 5 is pressed, the support plate 413 can be pressed and rotated so that its end enters the through grooves 4121. After the guide 5 is basically aligned by the two sets of conical mating structures, it is pressed by the driving member 9. It can be radially offset corrected in the assembly adjustment member 4, accurately pressed, and avoids 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 mounting base 3 is slidably connected above the slide rail 7, and the transverse cylinder 8 is fixedly connected to the bottom of the shock absorber mounting base 3. The piston rod end of the transverse cylinder 8 is rigidly connected to the bottom of the shock absorber mounting base 3 by a flange. Through pneumatic control, the transverse cylinder 8 drives the shock absorber mounting base 3 to perform horizontal reciprocating motion along the slide rail 7, realizing the precise insertion / removal operation of the shock absorber assembly below the assembly station, and completing the rapid replacement process of different shock absorber modules.

[0053] According to an embodiment of the present invention, guide columns 31 are symmetrically arranged on both sides above the shock absorber mounting base 3. A fixing plate 32 is slidably connected to the guide column 31. An assembly guide sleeve 6 is fixedly connected to the middle of the fixing plate 32. A spring 33 is sleeved on the outer side of the guide column 31. The lower end of the spring 33 abuts against the bottom of the fixing plate 32. A limiting block 34 is fixed above the guide column 31 to limit the highest position of the fixing plate 32. When the assembly adjusting component 4 is driven by the driving component 9 and pressed tightly against the assembly guide sleeve 6, the design of the spring 33 provides elastic buffering, allowing the assembly guide sleeve 6 to move downward a certain distance to generate controllable displacement, avoiding excessive contact stress between the assembly adjusting component 4 and the assembly guide sleeve 6. At the same time, when the shock absorber is pressed and pushes open the support plate 413, the assembly guide sleeve 6 can also move downward slightly to weaken part of the impact load, avoiding rigid contact assembly damage between the guide 5 and the shock absorber body.

[0054] The driving component 9 consists of two opposing linear modules fixedly connected to both sides of the bracket 1. The two sides of the annular housing 43 are fixedly connected to the slides of the linear modules. The linear modules drive the annular housing 43 to move, thereby pressing the assembly adjustment component 4 and the assembly guide sleeve 6 together.

[0055] It should be understood that the cutting device according to the embodiments of the present invention has all the features and advantages of the alignment mechanism described above, which can be found in the above description and will not be repeated here.

[0056] Those skilled in the art will understand that the features described in the various embodiments of the present invention can be combined or combined in various ways, even if such combinations or combinations are not explicitly described in the present invention. In particular, the features described in the various embodiments of the present invention can be combined and / or combined in various ways without departing from the spirit and teachings of the present invention. All such combinations and / or combinations fall within the scope of the present invention.
