Description

Technical Field

[0001] This utility model relates to the field of automotive shock absorber oil reservoir technology, and in particular to a necking tool for automotive shock absorber oil reservoir. Background Technology

[0002] The oil reservoir necking fixture is a special tool used for necking the oil reservoir. It usually consists of two parts: the necking fixture and the fixing fixture. There is a close matching relationship between the automotive shock absorber and the oil reservoir necking fixture assembly. As one of the core components of the automotive shock absorber, the machining accuracy of the necking part of the oil reservoir directly affects the sealing performance, assembly accuracy and overall shock absorption effect of the shock absorber.

[0003] Existing technology patent document CN217370133U discloses a necking fixture for an automotive shock absorber oil reservoir, including an oil reservoir, a necking fixture, and a fixing fixture. The necking fixture includes a die and a punch, and the fixing fixture includes an upper clamp and a lower clamp. The upper and lower clamps clamp the oil reservoir. The punch is located inside the oil reservoir, and the die is located outside the oil reservoir. The punch is fixedly connected to a punch core rod, and the die is movably connected to a horizontal extrusion cylinder. Compared with traditional necking fixtures, this invention changes the traditional vertical downward pressing to a horizontal horizontal extrusion, allowing for thicker walls of the necked oil reservoir, ensuring the necking implementation in space. Furthermore, the punch and die undergo vacuum quenching and tempering, surface TD treatment, and are adjusted to a rounded transition, extending the die's service life. The use of the punch ensures the coaxiality and outer roundness of the necked oil reservoir, improving the yield rate.

[0004] In the existing technology, when the oil reservoir is necked, it can be adjusted to a rounded transition, which extends the service life of the die. However, when some oil reservoirs are necked, it is impossible to protect oil reservoir columns of different specifications, thereby reducing the safety of the equipment, increasing the cost, and reducing the processing efficiency.

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] Please see Figure 1 , Figure 2 and Figure 4This utility model provides a technical solution: a necking fixture for an automotive shock absorber reservoir, including a support base plate 1. The support base plate 1 ensures the structural stability of the entire necking fixture during operation, providing reliable basic support for subsequent fixing, necking, heating, and cooling processes, thereby improving the overall service life and operational safety of the fixture. A vertical plate 2 is fixedly connected to the top right side of the support base plate 1. The vertical plate 2 installs and fixes the cylinder 5301 in the pull-out assembly 53, providing a stable support point for the cylinder 5301, while ensuring that the driving direction of the cylinder 5301 is consistent with the axis of the reservoir column 4. A protection mechanism 3 is provided inside and outside the support base plate 1. The protection mechanism 3 includes a T-support plate 31, which ensures the installation stability of the fixing seat 32 and the support seat a33. The bottom of the T-support plate 31 is fixedly connected to the top of the support base plate 1, and the top of the T-support plate 31 is fixedly connected to the fixing seat 32, providing a stable support for the reservoir column 4. The reference is placed, and the cylinder is fixed with fastening block 36. The top of the T-support plate 31 is fixedly connected to the support seat a33. The support seat a33 serves as one of the rotation fulcrums of the L-shaped follower rod 35, providing an upper rotation shaft for the L-shaped follower rod 35, limiting its rotation trajectory, and ensuring that the L-shaped follower rod 35 can stably drive the fastening block 36 to move. The support base plate 1 is fixedly connected to the support seat b34. The support seat b34 is both the lower rotation fulcrum of the L-shaped follower rod 35 and the driving force-bearing component of the power assembly 38. It drives the L-shaped follower rod 35 to rotate through its own sliding, thereby realizing the motion control of the fastening block 36. The L-shaped follower rod 35 is rotatably connected inside the support seat a33 and inside the support seat b34. The L-shaped follower rod 35 serves as a transmission component, connecting the support seat a33, the support seat b34 and the fastening block 36, converting the horizontal sliding of the support seat b34 into the vertical movement of the fastening block 36, thereby realizing the fixing and release of the oil storage cylinder 4.

[0025] A fastening block 36 is fixedly connected to the bottom left side of the L-shaped follower rod 35, which cooperates with the fixing seat 32. Through up-and-down movement, it fixes the oil reservoir column 4. The protective fastening pad 37 at its bottom directly contacts the column, ensuring a firm fixation without damaging the surface. Protective fastening pads 37 are fixedly connected to the top of the fixing seat 32 and the bottom of the fastening block 36. These protective fastening pads 37 effectively protect the outer surface quality of the oil reservoir column 4 while ensuring reliable fastening, reducing surface damage during processing. A power assembly 38 is fixedly connected inside the support base plate 1. The power assembly 38 includes an electric telescopic rod 3801. The electric telescopic rod 3801 drives the support seat b34 to slide left and right through telescopic movement, thereby controlling the movement of the L-shaped follower rod 35 and the fastening block 36. The electric telescopic rod 3801 is externally fixedly connected to the inside of the support base plate 1. The drive end of the electric telescopic rod 3801 is fixedly connected to the left side of the support seat b34. A support base 3803 is fixedly connected to the left side of the electric telescopic rod 3801. The support base 3803 raises... The installation rigidity of the electric telescopic rod 3801 ensures the stability of its driving direction. The bottom left side of the T-support plate 31 is fixedly connected to the limit post 3802. The limit post 3802 reduces the damage to the L-shaped follower rod 35 and the electric telescopic rod 3801 caused by excessive sliding of the support seat b34, ensuring the safety and stability of the mechanism's movement and extending the service life of the components. The oil reservoir column 4 is slidably connected to the adjacent side of the two protective fastening pads 37. The oil reservoir column 4 is the processing object of this tooling, namely the semi-finished product of the car shock absorber oil reservoir that needs to be necked. The two sides of the limit post 3802 are fixedly connected to the inside of the support base plate 1. The top of the support base plate 1 is provided with a pushing mechanism 5. The pushing mechanism 5 includes two drive slide rails 52. The drive slide rails 52 provide stable linear drive to ensure that the pushing frame 51 drives the oil reservoir column 4 to slide. The bottom of the two drive slide rails 52 is fixedly connected to the top of the support base plate 1. The top of the two drive slide rails 52 is fixedly connected to the pushing frame 51. The inside of the oil reservoir column 4 is slidably connected to the pull-out assembly 53.

[0026] The pull-out assembly 53 includes a cylinder 5301, which ensures that the necking component 5304 can effectively perform necking processing on the heated oil reservoir column 4. The processing force and stroke can be adjusted through the parameters of the cylinder 5301 to adapt to different necking requirements. The cylinder 5301 is externally fixedly connected to the left side of the vertical plate 2. A push rod 5302 is fixedly connected to the drive end of the cylinder 5301. The push rod 5302 connects the cylinder 5301 and the connecting plate 5303, transmitting the driving force of the cylinder 5301 and transmitting the extension and retraction movement of the cylinder 5301 to the necking component 5304. The connecting plate 5303 is fixedly connected to the left side of the push rod 5302. 03 Connects the push rod 5302 and the necking part 5304 to facilitate the disassembly and replacement of the necking part 5304 to adapt to different specifications of oil storage cylinder column 4. The necking part 5304 is detachably connected to the left side of the connecting plate 5303. The connecting plate 5303 and the necking part 5304 can be quickly replaced by bolts. The external of the cylinder 5301 is slidably connected to the inside of the push frame 51 to realize the movement of the oil storage cylinder column 4 in different process areas. The left side of the push frame 51 is slidably connected to the right side of the oil storage cylinder column 4, and the external of the necking part 5304 is slidably connected to the inside of the oil storage cylinder column 4. The top of the support base plate 1 is fixedly connected to the heating and cooling mechanism 6.

[0027] like Figure 1 , Figure 3 and Figure 5 As shown, the heating and cooling mechanism 6 includes a support frame a61. The support frame a61 improves heating efficiency, reduces heat loss to the external environment, and protects external components from high temperatures, providing a stable high-temperature environment for necking processing. The support frame a61 is fixedly connected to the top of the support base plate 1. The top of the support base plate 1 is fixedly connected to a support frame b62. The support frame b62 serves as a protective and support frame for the cooling area, providing installation space for the cooling wire 65, cooling plate 66, and cooling fan 67, forming a cooling chamber to accelerate the cooling of the oil storage cylinder 4. Heating plates 63 are fixedly connected to both sides of the inner wall of the support frame a61 as the main heating components. The heating plates 63 generate heat through electric heating to heat the oil storage cylinder 4 inside the support frame a61 from the side, so that the cylinder reaches the temperature required for plastic deformation. Multiple heating blocks 64 are fixedly connected to the top side of the inner wall of the support base plate 1. The heating blocks 64 assist the heating plates 63 in heating the oil storage cylinder 4, mainly supplementing heat from the top and other sides, further improving heating uniformity and heating speed.

[0028] Multiple cooling wires 65 are fixedly connected to both sides of the inner side of the support frame b62. The cooling wires 65 quickly absorb heat from the cylinder from the side, accelerating the cooling speed and quickly fixing the shape of the necked cylinder, avoiding shape rebound caused by slow cooling. Two cooling plates 66 are fixedly connected to the top side of the inner wall of the support frame b62. The cooling plates 66 serve as the mounting carrier for the cooling wires 65 and transfer the cold energy generated by the cooling wires 65 to the internal space of the support frame b62, thereby cooling the internal environment. A cooling fan 67 is fixedly connected to the top of the support frame b62. The cooling fan 67 accelerates the airflow inside the support frame b62, enhancing the heat dissipation and cooling effect. Charging interfaces 68 are respectively opened on the left side of the inner side of the support frame a61 and the left side of the inner side of the support frame b62. When an external power source is connected through the charging interface 68, electrical energy is transmitted to each electrical component through the internal circuitry, providing power support for its normal operation. The far sides of multiple heating blocks 64 are fixedly connected to the near sides of two heating plates 63, and the near sides of the cooling plates 66 are fixedly connected to the near sides of multiple cooling wires 65.

[0029] Working principle: First, during use, the oil reservoir column 4 is placed on top of the fixed base 32 and one of the protective fastening pads 37. At the same time, the electric telescopic rod 3801 is activated, which pushes the support base b34. Simultaneously, the L-shaped follower rod 35 rotates inside the support base b34 and support base a33, thereby causing the fastening block 36 and the other protective fastening pad 37 to move downward, thus fixing the oil reservoir column 4. When the electric telescopic rod 3801 retracts, it pulls the support base b34 to slide to the left, thereby causing the L-shaped follower rod 35 to rotate upward inside the support base a33 and support base b34, thus releasing the oil reservoir column 4 and fixing and protecting it.

[0030] Secondly, the heating plate 63 and heating block 64 are activated, and the cylinder 5301 is also activated to push the push rod 5302, thereby causing the oil reservoir column 4 of the necking part 5304 to slide. When heating is performed externally, the necking part 5304 is pulled out to neck the oil reservoir of the car shock absorber. After heating is completed, the push frame 51 is driven by the drive slide rail 52 to push the oil reservoir column 4 into the support frame b62, thereby activating the cooling wire 65 and cooling plate 66. The top cooling fan 67 works together to quickly cool the tooling after the necking is completed.

[0031] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
