Description

Technical Field

[0001] This utility model relates to an assembly tooling, specifically to an air filter shock absorber assembly tooling. Background Technology

[0002] During the assembly of automotive air filter damping pads, due to the product's unique structure, the pad's ends are larger than the mounting holes on the air filter housing, and there is an annular mounting groove in the middle with a diameter similar to the mounting holes. Deforming one end of the damping pad requires significant pressure, making assembly extremely difficult. Previously, this type of product was typically assembled manually using a handheld tool to forcibly press the damping pad in, which has two major drawbacks. Drawback 1: Assembly efficiency is very low, and incomplete assembly and poor consistency are frequent, with some products at risk of the damping pad detaching. Drawback 2: Handheld tools easily damage the damping pad and are difficult to identify, leading to defective products reaching the customer. To effectively overcome these drawbacks, a suitable air filter damping pad assembly fixture is urgently needed that can improve assembly efficiency, ensure the consistency of the assembled damping pad, and effectively protect the product from damage. Utility Model Content

[0003] The present invention aims to provide a suitable assembly fixture for air filter damping pads, eliminating the risk of the damping pads coming off.

[0004] The air filter damping pad assembly fixture in this solution includes a positioning device and a clamping device. The positioning device includes a support that can fix the air filter housing. The clamping device includes a slidingly fitted clamping part and a guide sleeve. The clamping part can pass through the guide sleeve and is located above the guide sleeve. The clamping part includes a pair of clamps. When the clamps slide into the guide sleeve, they move towards each other. When the clamps slide out of the guide sleeve, they move away from each other. The guide sleeve is coaxial with the mounting hole of the air filter housing.

[0005] The advantages of this invention are: 1) One end of the shock-absorbing pad undergoes elastic deformation in the radial direction after being clamped. Simultaneously, during installation, the shock-absorbing pad rotates 90°, allowing the elastically deformed end to pass smoothly through the mounting hole, effectively preventing damage to the shock-absorbing pad by installation tools and preventing defective products from entering the customer's shop. 2) The shock-absorbing pad is assembled using the clamping part, resulting in good assembly consistency. 3) The shock-absorbing pad is properly assembled, with the mounting hole fitting into the annular mounting groove, eliminating the risk of the shock-absorbing pad coming out. 4) It reduces the workload of workers and improves assembly efficiency.

[0006] Furthermore, the clamping device also includes a slide block and a pair of sliders, with an elastic element between the two sliders; the sliders are located below the chuck, separating when the chuck extends out of the guide sleeve; a guide ramp is provided between the chuck and the sliders, bringing them together when the chuck slides into the guide sleeve. The opening and closing of the chuck can be achieved through this simple structure, enabling the assembly of the shock-absorbing pad.

[0007] Furthermore, the sidewall of the clamp is arc-shaped, which can better accommodate one end of the shock-absorbing pad; the clamp is also provided with a clearance opening, and the annular mounting groove of the shock-absorbing pad is located at the clearance opening to prevent the clamp from popping out when the shock-absorbing pad is deformed during clamping.

[0008] Furthermore, the upper end of the clamp is beveled. This facilitates the flipping and assembly of the shock-absorbing pad when the clamp pulls it into the mounting hole.

[0009] Furthermore, the inner diameter of the guide sleeve is smaller than the mounting hole of the air filter housing.

[0010] Furthermore, the support is provided with a positioning groove adapted to the air filter housing. Since the clamps extend out of the guide sleeve and the mounting holes of the air filter housing, the distance between the two clamps is approximately equal to the end diameter of the shock-absorbing pad, that is, the distance between the two clamps is greater than the diameter of the mounting hole; during assembly, the clamps move downward along the Z direction, one end of the shock-absorbing pad passes through the mounting hole, and the other end abuts against the end face of the mounting hole, thus positioning the air filter housing in the X and Y directions is sufficient.

[0011] Furthermore, the clamping device also includes a lifting platform fixedly connected to the slide, and the lifting platform is equipped with a driving device. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0021] according to Figures 1 to 7 As shown, the air filter damping pad 3 assembly fixture includes a positioning device 1 and a clamping device 2 fixed on the worktable 5, and a lifting platform 2-5 located below the worktable 5. The lifting platform 2-5 is equipped with a drive device 2-6, preferably a cylinder. The clamping device 2 includes a slidingly fitted clamping part and a guide sleeve 2-2, as well as a slide block 2-4 and a pair of sliders 2-3. The guide sleeve 2-2 is coaxial with the mounting hole 4-1 of the air filter housing 4; the slide block 2-4 is bolted to the lifting platform 2-5. The slide block 2-4 and the pair of sliders 2-3 are located below the clamping part, and an elastic element is provided between the two sliders 2-3, preferably a compression spring. Specifically, the clamping part includes a pair of chucks 2-11, the chucks 2-11, the connecting rod, and the sliders 2-3 are integrally formed, and the lower part of the chucks 2-11 is provided with a guide slope 2-13. The chucks 2-11 can pass through the guide sleeve 2-2 and are located above the guide sleeve 2-2. When the chuck 2-11 slides into the guide sleeve 2-2, it moves towards the opposite direction; when the chuck 2-11 slides out of the guide sleeve 2-2, it moves away from the opposite direction. The inner diameter of the guide sleeve 2-2 is smaller than the mounting hole 4-1 of the air filter housing 4. The positioning device 1 includes a support 1-1 that can fix the air filter housing 4. The support 1-1 is provided with a positioning groove 1-2 that conforms to the shape of the air filter housing 4. The air filter housing 4 fits into the positioning groove 1-2, which can effectively fix the air filter housing 4. In this embodiment, there are four supports 1-1, which are located at the four corners of the air filter housing 4, which can ensure that the clamping device 2 has sufficient installation space.

[0022] As a further improvement of this embodiment, when the shock-absorbing pad 3 is placed on the chuck 2-11, the axis of the shock-absorbing pad 3 is perpendicular to the axis of the mounting hole 4-1; during the assembly process, it is necessary to flip the shock-absorbing pad 3 to be coaxial with the mounting hole 4-1. Therefore, the upper end of the chuck 2-11 is set as an inclined surface. When the chuck 2-11 pulls the shock-absorbing pad 3 into the mounting hole 4-1, it is convenient for the shock-absorbing pad 3 to flip and thus be assembled smoothly.

[0023] As a further improvement of this embodiment, the chuck 2-11 is also provided with a clearance opening 2-12, one end of the shock-absorbing pad 3 is placed between the chucks 2-11, and the annular mounting groove 3-1 is engaged at the clearance opening 2-12 to prevent the shock-absorbing pad 3 from popping out of the chuck 2-11 when it is deformed during clamping. The side wall of the chuck 2-11 is preferably arc-shaped to limit the position of the shock-absorbing pad 3.

[0024] The assembly process is as follows:

[0025] Step 1: Place the air filter housing 4 on the support 1-1 to position it.

[0026] Step 2: The lifting platform 2-5 drives the slide 2-4 to rise, and the chuck 2-11 extends out from the guide sleeve 2-2 and automatically opens through the compression spring.

[0027] Step 3: Place one end of the shock-absorbing pad 3 into the clamp 2-11. The cylinder drives the lifting platform 2-5 to descend. The clamp 2-11 slides into the guide sleeve 2-2. Under the action of the guide inclined surface 2-13, the clamp 2-11 moves closer and squeezes the shock-absorbing pad 3 to deform it, and smoothly pulls it into the air filter housing 4 at the mounting holes 4-1.

[0028] Step 4: Remove the product and repeat the above steps.

[0029] The above description is merely an embodiment of this utility model, and common knowledge such as specific structures and characteristics of the solution is not described in detail here. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these should also be considered within the protection scope of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
