[0016] Step 1: Place the hexagonal socket head cap screw on the hexagonal fixing platform inside the fixture, start the conveying system, and transport the fixture to the area directly below the gasket assembly mechanism.
[0017] Step 2: Start the lifting cylinder to move the feeding cylinder and guide cylinder downwards until the bottom surface of the guide cylinder is in contact with the placement fixture.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0037] The present invention is as follows Figures 1-5As shown, a vibration damping pad assembly for an integrated module in the front compartment of an automobile is designed. The vibration damping pad assembly includes an internal hexagon bolt 1, a limiting washer 2 and an inner mounting tube 4 fitted onto the internal hexagon bolt 1, wherein the limiting washer 2 is located near the head of the internal hexagon bolt 1, and one end of the inner mounting tube 4 abuts against the limiting washer 2. An H-beam rubber pad 3 is installed on the inner mounting tube 4, wherein one end of the H-beam rubber pad 3 abuts against the limiting washer 2. The internal hexagon bolt 1, the limiting washer 2, the inner mounting tube 4 and the H-beam rubber pad 3 form a vibration damping pad assembly, which is installed between the thermal management integrated module in the front compartment of the automobile and the body crossbeam. It serves to attenuate the vibration excitation source generated when the thermal management integrated module is working, reduce the vibration and noise transmitted to the vehicle interior when the thermal management integrated module is working, and thus improve the NVH comfort of the entire vehicle.
[0038] The limiting washer 2 is an arc shape with a concave center. When it is fitted onto the internal hex bolt 1, the concave opening is as follows: Figure 2 As shown, an upward-facing, compression protrusion 21 is provided on the top surface of the edge of the limiting gasket 2. This compression protrusion 21 is arranged in a ring shape. During the assembly of the whole component, as shown... Figure 5 As shown, the I-beam rubber pad 3 is subjected to an inwardly inclined compressive force by the extrusion protrusion 21 during assembly (the extrusion protrusion 21 is an interference fit), thereby deforming the I-beam rubber pad 3 inward and further limiting the radial offset of the inner tube 4.
[0039] Further, such as Figure 2 and Figure 4 As shown, the vertical cross-section of the above-mentioned I-shaped rubber pad 3 is I-shaped and has an internal cavity. During assembly, the I-shaped rubber pad 3 and the internal cavity are assembled by inserting the mounting inner tube 4 into the internal cavity of the I-shaped rubber pad 3.
[0040] Further, such as Figure 4 As shown, the I-shaped rubber pad 3 has multiple sound-absorbing deformation holes 31 on its central axial surface, and the multiple sound-absorbing deformation holes 31 are distributed at equal angles around the vertical center line of the I-shaped rubber pad 3, and are arranged in two groups, upper and lower.
[0041] Details such as Figure 4 As shown, the sound-absorbing deformation hole 31 is shaped like an oblique horn, with the larger diameter facing outward and the smaller diameter facing inward. The horn is tilted towards the horizontal centerline of the I-shaped rubber pad 3. The inner and outer edges of the sound-absorbing deformation hole 31 are rounded to avoid stress concentration when the I-shaped rubber pad 3 is squeezed and deformed inward, which could cause the sound-absorbing deformation hole 31 to break and thus affect the service life of the entire I-shaped rubber pad 3.
[0042] Furthermore, a limiting boss 33 is provided in the middle of the inner cavity of the aforementioned I-shaped rubber pad 3. The limiting boss 33 is annular and its diameter is larger than the diameter of the upper and lower end cavities of the I-shaped rubber pad 3. The limiting boss 33 further limits and fixes the axial surface of the inner tube 4 when the I-shaped rubber pad 3 deforms inward, making the installation more stable.
[0043] Furthermore, the aforementioned I-beam rubber pad 3 has a sound-absorbing pad 32 installed on the inner wall of its cavity. Two sets of these sound-absorbing pads 32 are arranged in a ring shape, located at the upper and lower ends of the limiting boss 33, respectively. The sound-absorbing pads 32 are made of sound-absorbing cotton. By installing the sound-absorbing pads 32 and multiple sets of sound-absorbing deformation holes 31, the noise generated by the vibration of the thermal management integrated module is absorbed, further attenuating the noise transmitted to the cabin through automotive structural components and reducing the driver's NVH comfort.
[0044] Further, such as Figure 3 As shown, the inner tube 4 has an installation hole inside and a downwardly recessed blocking part on the outside. The blocking part cooperates with the limiting washer 2 to squeeze and limit the I-beam rubber pad 3. A protruding threaded part 41 is provided at the head of the installation hole. The threaded part 41 is threadedly connected to the internal hex bolt 1, making it less likely for the whole assembly to fall apart after assembly and easier to install. Furthermore, the solid connection between the internal hex bolt 1 and the inner tube 4 makes the combination of internal hex bolt 1, limiting washer 2, inner tube 4 and I-beam rubber pad 3 more secure.
[0045] Furthermore, the upper end of the I-beam rubber pad 3 is interference-fitted to prevent the I-beam rubber pad 3 from shaking during operation.
[0046] Furthermore, during the overall assembly, the edge of the I-beam rubber pad 3 is squeezed by the interference-fitted extrusion protrusion 21, causing the I-beam rubber pad 3 to be subjected to an inwardly inclined extrusion force, which deforms the I-beam rubber pad 3 inward. This further causes the limiting protrusion 33 to contact the inner tube 4 inward, and the inclined sound-absorbing deformation hole 31 makes it easier for the extrusion protrusion 21 to squeeze the I-beam rubber pad 3 inward.
[0047] Furthermore, the shock-absorbing pad assembly is assembled using assembly equipment, which includes a conveying system 5 on which a placement fixture 6 is mounted, and the conveying system 5 carries materials from the feed end ( Figure 6 From the left side to the discharge end, a gasket assembly mechanism 7 and a rubber gasket assembly mechanism 8 are sequentially set up. The gasket assembly mechanism 7 and the rubber gasket assembly mechanism 8 sequentially assemble the internal hexagon bolts 1 conveyed on the conveying system 5, and finally complete the overall assembly, improve the assembly efficiency, and ensure the assembly accuracy.
[0048] The conveyor system 5 is a transmission belt conveyor structure in the prior art, which will not be described in detail here;
[0049] Further placement of tooling 6, etc. Figure 6 and Figure 7 As shown, the system includes a placement box body 61 mounted on the transmission belt of the conveying system 5. An adjustment cavity is provided inside the placement box body 61. A limit clamp 62 is provided in the middle of the bottom of the adjustment cavity, and an adjustment seat 63 is slidably mounted in the adjustment cavity. Various types of hexagonal fixing platforms are sequentially arranged on the top of the adjustment seat 63. The hexagonal fixing platforms are adapted to the corresponding types of internal hexagonal bolts 1. Triangular grooves are provided at the bottom of the multiple hexagonal fixing platforms. The triangular grooves are adapted to the limit clamp 62 to limit the adjustment seat 63. The adjustment seat 63 is adjusted using the corresponding hexagonal fixing platforms for different types of internal hexagonal bolts 1. A placement hole 64 is provided in the middle of the top surface of the placement box body 61. The placement hole 64 passes through the adjustment cavity. The initial feeding is performed by installing the internal hexagonal bolts 1 and the hexagonal fixing platforms below the placement hole 64.
[0050] Further, such as Figure 6 and Figure 8 As shown, the aforementioned gasket assembly mechanism 7 includes a mounting plate 71. A pad is provided on the back of the mounting plate 71, and a lifting cylinder 78 is fixedly mounted on the pad. The telescopic rod of the lifting cylinder 78 is connected to a connecting rod, and the other end of the connecting rod is connected to a discharge cylinder 72. The discharge cylinder 72 is located on the front of the mounting plate 71. The connecting rod is slidably connected to the mounting plate 71 (a groove is provided in the middle of the mounting plate 71). A guide cylinder 74 is connected to the bottom of the discharge cylinder 72, and a discharge cavity 73 is passed through the middle of the discharge cylinder 72. A guide cavity is provided in the middle of the guide cylinder 74. The guide cavity is connected to... The discharge chamber 73 is connected, and a locking component 77 is provided at the bottom of the discharge chamber 73. Multiple limiting pads 2 are stacked in the discharge chamber 73. The locking component 77 restricts the position of the limiting pads 2. A fixing plate 75 is provided on one side of the front of the discharge cylinder 72. A release motor 76 is installed on the fixing plate 75. The output shaft of the release motor 76 passes through the fixing plate 75 and is connected to an adjusting gear 79. The adjusting gear 79 is connected to the locking component 77 to control the movement of the locking component 77 and realize the orderly falling of multiple limiting pads 2.
[0051] Further, such as Figure 9 and Figure 10 As shown, the aforementioned locking assembly 77 includes an adjusting plate 771 disposed inside the feeding cylinder 72. Telescopic grooves 772 are symmetrically arranged above the adjusting plate 771 and on both sides of the feeding cylinder 72. A locking plate 773 is disposed within the telescopic groove 772, and a spring is connected to the tail of the locking plate 773. The spring provides elastic force for the telescopic movement of the locking plate 773. The adjusting plate 771, as shown... Figure 10As shown, the arrangement is circular. An adjusting ring platform 7710 is located on the top inner ring of the adjusting disc 771. This adjusting ring platform 7710 has protruding pressing bosses 7711 corresponding to the positions of the two snap-fit plates 773. A sector-shaped toothed platform 7712 is located on one side of the outer edge of the adjusting disc 771. The side of the sector-shaped toothed platform 7712 has tooth grooves, which mesh with the adjusting gear 79. The adjusting gear is driven by the start-release motor 76. When gear 79 rotates, the adjusting gear 79 drives the adjusting disc 771 to deflect. The deflected adjusting disc 771 drives the pressing boss 7711 to move. When the pressing boss 7711 corresponds to the snap-fit plate 773, the snap-fit plate 773 is squeezed into the telescopic groove 772, and the limiting pad 2 falls. When the pressing boss 7711 leaves the snap-fit plate 773, the snap-fit plate 773 extends out of the telescopic groove 772 to limit the limiting pad 2 and prevent the limiting pad 2 from falling. The falling process is controlled by time.
[0052] Further, such as Figure 6 As shown, the aforementioned rubber pad assembly mechanism 8 includes a bracket 81 mounted on the conveying system 5. A robotic arm 82 is mounted on top of the bracket 81, and a mechanical gripper 83 is connected to the robotic arm 82. The mechanical gripper 83 grips the assembly of the inner tube 4 and the I-beam rubber pad 3 and assembles it onto the internal hex bolt 1 with the limit washer 2 installed, thus assembling the entire component. The assembly of the inner tube 4 and the I-beam rubber pad 3 is then assembled by other production lines.
[0053] A further method for assembling this shock-absorbing pad assembly includes the following steps:
[0054] Step 1: Place the hexagonal socket head cap screw 1 on the hexagonal fixing platform inside the placement fixture 6, start the conveying system 5, and convey the placement fixture 6 to the area directly below the gasket assembly mechanism 7.
[0055] Step 2: Start the lifting cylinder 78 to move the feeding cylinder 72 and the guide cylinder 74 down until the bottom surface of the guide cylinder 74 is in contact with the placement fixture 6. Start the release motor 76 to drive the adjusting gear 79 to rotate. The adjusting gear 79 drives the adjusting plate 771 to deflect, so that the pressing boss 7711 of the adjusting plate 771 presses the snap-fit plate 773, releasing the limit shim 2. After the limit shim 2 is released, the release motor 76 drives the adjusting gear 79 to reverse, and the adjusting gear 79 drives the adjusting plate 771 to reset, limiting the limit shim 2.
[0056] Step 3: After the limit pad 2 is installed, the conveying system 5 will transport the placement fixture 6 to the bottom of the rubber pad assembly mechanism 8. The robotic arm 82 and the mechanical gripper 83 will be activated to grab the assembly of the inner tube 4 and the I-shaped rubber pad 3 on the adjacent production line, put it on the internal hex bolt 1, and rotate the mechanical gripper 83 to install the assembly of the inner tube 4 and the I-shaped rubber pad 3 with the internal hex bolt 1, thus completing the assembly of the shock-absorbing pad assembly.
