Description

Technical Field

[0001] This utility model belongs to the field of steering knuckles, and specifically relates to a steering knuckle heat treatment and shaping auxiliary device. Background Technology

[0002] Currently, there are two main types of front steering knuckles for automobiles: MacPherson strut and double wishbone. MacPherson struts are a versatile option for urban commuting, standard on 90% of family cars. They offer advantages such as simple structure, low cost, small footprint, smooth vibration filtering over speed bumps, and easy maintenance. With increasing demands for better vehicle handling and driving experience, double wishbone steering knuckles were developed. The upper and lower A-arms of a double wishbone steering knuckle precisely control wheel camber, resulting in minimal body roll during cornering, strong grip, and stability like a railcar during high-speed cornering.

[0003] However, the double wishbone steering knuckle has a very long gooseneck, which is not only complex in structure but also huge in shape. After differential pressure casting, it needs to be heat-treated. During the heat treatment process, due to the slow cooling and shrinkage, it is not easy to form, so deformation is prone to occur at the gooseneck. Utility Model Content

[0004] This invention proposes a heat treatment and shaping auxiliary device for steering knuckles to solve the problem of easy deformation at the gooseneck of double wishbone steering knuckles in the prior art.

[0005] To achieve the above objectives, the present invention proposes the following technical solution: A steering knuckle heat treatment shaping auxiliary device includes a support frame and two sets of deformation clamping assemblies; The support frame is provided with a slot, and the deformation clamping component is disposed inside the slot; The deformation clamping assembly includes a first clamping block, a second clamping block, and a connecting spring. The first clamping block is connected to the second clamping block via the connecting spring, and the second clamping block is connected to the inner wall of the slot.

[0006] Preferably, both the first clamping block and the second clamping block are made of alloy.

[0007] The advantages of this utility model are: This utility model proposes a steering knuckle heat treatment shaping auxiliary device. By setting a deformation clamping component, it can perform elastic compression at the gooseneck when the double wishbone steering knuckle begins to cool and shrink for shaping. This helps the gooseneck of the double wishbone steering knuckle to quickly return to its standard shape during shrinkage, avoiding the problem that the steering knuckle is not easy to form after differential pressure casting, has slow cooling and shrinkage, and is prone to deformation at the gooseneck.

In the drawings: Figure 1 This is a schematic diagram of a steering knuckle heat treatment shaping auxiliary device; Figure 2 This is a schematic diagram showing the location of the deformation clamping component; Figure 3 This is a schematic diagram showing the distribution of the deformation clamping components; Figure 4 This is a schematic diagram of the deformation clamping assembly. Detailed Implementation

[0009] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0010] The following detailed description is exemplary and intended to provide further detailed explanation of the present invention. Unless otherwise specified, all technical terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this invention.

[0011] Please see Figure 1 As shown, this utility model provides a steering knuckle heat treatment shaping auxiliary device, including a support frame 1 and a deformation clamping assembly 3.

[0012] The support frame 1 is provided with four fixed columns 11 at its four bottom ends for stabilizing and fixing the frame 1. The number of fixed columns 11 is four.

[0013] like Figure 2 , 3 As shown, a slot 2 is provided on the upper part of the support frame 1. The shape of the slot 2 matches the appearance of the double wishbone steering knuckle. A deformation clamping component 3 is fixedly installed inside the slot 2.

[0014] like Figure 4As shown, the deformation clamping assembly 3 includes a first clamping block 31, a second clamping block 32, and a connecting spring 33 for connecting the first clamping block 31 and the second clamping block 32. The distance between the first clamping blocks 31 of the two sets of deformation clamping assemblies 3 when the spring 33 is pressed is the deformation amount at the gooseneck of the double wishbone steering knuckle when it begins to cool; when the spring 33 returns to its natural state, the distance by which the first clamping blocks 31 are pressed inward is the normal contraction amount at the gooseneck of the double wishbone steering knuckle; there are two sets of deformation clamping assemblies 3, which are respectively arranged on the upper and lower sides of the gooseneck of the double wishbone steering knuckle. The first clamping block 31 and the second clamping block 32 are both made of alloys that are not easily deformed.

[0015] By incorporating the deformation clamping component 3, elastic compression can be applied at the gooseneck of the double wishbone steering knuckle as it begins to cool, shrink, and solidify. This helps the gooseneck of the double wishbone steering knuckle quickly return to its standard shape during shrinkage, avoiding the problems of difficulty in forming after differential pressure casting, slow cooling and shrinkage, and easy deformation at the gooseneck. Deformed double wishbone steering knuckles are unusable, leading to excessive waste and low production efficiency.

Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones.
