Description

Technical Field

[0001] This utility model relates to the field of automotive shock absorber assembly technology, specifically a tooling for installing shock absorber dust covers. Background Technology

[0002] The traditional shock absorber upper support assembly consists of three parts: upper support, compression buffer block, and dust cover. The end of the compression buffer block is installed inside the cup of the upper support, and one end of the dust cover is snapped and fixed to the outer surface of the cup of the upper support.

[0003] The existing assembly process for the upper support of the shock absorber has two major technical challenges:

[0004] 1. The installation sequence is as follows: first install the compression buffer block, then install the dust cover. During dust cover installation, because the compression buffer block already occupies the internal space of the upper support, assembly of the dust cover is difficult, resulting in a product defect rate of approximately 3.2%, which is difficult to reduce.

[0005] 2. Manual operation requires high technical skills from workers, resulting in unstable installation quality and an average assembly time of 35 seconds per piece.

[0006] Therefore, it is necessary to design a tooling for installing dust covers on shock absorbers to achieve rapid installation of dust covers, reduce product defect rates, and eliminate differences in manual operation. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a tooling for installing dust covers for shock absorbers, so as to achieve rapid installation of dust covers, reduce product defect rate, and eliminate differences in manual operation.

[0008] To achieve the above objectives, this utility model is a tooling for installing a dust cover for a vibration damper, comprising a base, a guide cylinder, and a pressure cylinder. The top of the base has a planar structure supporting an upper support, and the planar structure has a clearance hole that matches the protruding structure at the bottom of the upper support. The guide cylinder is a hollow, trumpet-shaped structure, with an interior space for accommodating a compression buffer block. The exterior of the guide cylinder has a cylinder wall for the dust cover to be fitted onto. The diameter of the upper hand-held part of the guide cylinder is smaller than the diameter of the lower pressing part. The lower pressing part of the guide cylinder has an outwardly flared guide flange, the diameter of which matches the diameter of the cup opening of the upper support. The pressure cylinder is an inverted cylindrical cup-shaped structure, with the lower inner diameter of the pressure cylinder being larger than the upper outer diameter of the guide cylinder, and the lower inner diameter of the pressure cylinder being smaller than the bottom diameter of the dust cover.

[0009] The base has an outwardly extending boss on its edge, and bolt holes are provided on the boss. After the bolt passes through the bolt holes, it is fixed to the hydraulic press table.

[0010] The top of the pressure cylinder has a hydraulic press connection hole.

[0011] The aforementioned clearance holes include boss clearance holes and bolt clearance holes. The boss clearance holes match the boss protruding from the bottom of the upper support, and the bolt clearance holes match the bolt protruding from the bottom of the upper support.

[0012] Compared with the prior art, this utility model provides support and positioning for the upper support with a base, isolates the compression buffer block and dust cover with a guide cylinder, reduces the impact of the compression buffer block on the assembly of the dust cover, and achieves the snap-fit ​​between the dust cover and the upper support with a pressure cylinder. The assembly time is shortened to 8 seconds / piece, the efficiency is increased by 337%, the defect rate is reduced to below 0.05%, the variability of manual operation is eliminated, and the standardized operation of the shock absorber dust cover assembly is realized.

[0018] The present invention will now be further described with reference to the accompanying drawings.

[0019] See Figure 1 , Figure 2 This utility model is a tooling for installing a dust cover for a vibration damper, including a base, a guide cylinder, and a pressure cylinder. The top of the base 1 has a planar structure that supports the upper support 4. The planar structure has a clearance hole that matches the protruding structure at the bottom of the upper support 4. The guide cylinder 2 is a hollow trumpet-shaped structure. The interior of the guide cylinder 2 has a space to accommodate the compression buffer block 6. The exterior of the guide cylinder 2 has a cylinder wall for the dust cover 5 to be fitted. The diameter of the upper hand-held part of the guide cylinder 2 is smaller than the diameter of the lower pressing part. The lower pressing part of the guide cylinder 2 has an outwardly flared guide flange 2-1. The diameter of the guide flange 2-1 matches the diameter of the cup opening of the upper support 4. The pressure cylinder 3 is an inverted cylindrical cup-shaped structure. The lower inner diameter of the pressure cylinder 3 is larger than the upper outer diameter of the guide cylinder 2, and the lower inner diameter of the pressure cylinder 3 is smaller than the bottom diameter of the dust cover 5.

[0020] See Figure 3 The base 1 has an outwardly extending boss on its edge, with bolt holes 1-3 on the boss. Bolts pass through the bolt holes 1-3 and are then fixed to the hydraulic press table. (See also...) Figure 5The top of the pressure cylinder 3 has a hydraulic press connection hole 3-1, which is connected to the hydraulic press head.

[0021] The clearance holes include boss clearance hole 1-1 and bolt clearance hole 1-2. Boss clearance hole 1-1 matches the boss protruding from the bottom of the upper support 4, and bolt clearance hole 1-2 matches the bolt protruding from the bottom of the upper support 4, so as to avoid the boss and bolt of the upper support 4, and at the same time ensure the accurate positioning of the upper support 4 on the base 1.

[0022] See Figure 4 The upper end of the guide cylinder 2 is the hand-held part. The hand-held part has a small diameter to facilitate the worker's hand-holding and to avoid the space for the pressure cylinder 3 to press down.

[0023] When this utility model is in operation, the upper support 4 is placed flat on the top of the base 1, and the lower end of the guide cylinder 2 is placed at the cup mouth of the upper support 4. At this time, the compression buffer block 6 is placed inside the guide cylinder 2, and the dust cover 2 is sleeved on the outside of the cylinder wall of the guide cylinder 2. The compression buffer block 6 will not affect the assembly of the dust cover 2. The hydraulic press head drives the pressure cylinder 3 to press down, so that the buckle of the dust cover 2 is engaged with the cup mouth of the upper support 4.

[0024] In this invention, the base provides support and positioning for the upper support, the guide cylinder isolates the compression buffer block and the dust cover, reducing the impact of the compression buffer block on the assembly of the dust cover, and the pressure cylinder enables the dust cover to be snapped into place with the upper support. The assembly time is shortened to 8 seconds per piece, the efficiency is increased by 337%, the defect rate is reduced to below 0.05%, the variability of manual operation is eliminated, and the standardized operation of the shock absorber dust cover assembly is achieved.
