Technical Field

[0001] The utility model relates to the field of automobile parts manufacturing, in particular to a portable inspection tool for steering knuckle deformation. Background Art

[0002] As one of the important parts of automobile chassis, automobile steering plays a vital role in driving safety. Steering knuckle products are usually complex in shape, with complicated processing procedures and many changing points. In addition, since the tail end of the steering knuckle has a slender "gooseneck structure", it is easy to deform the tail end after cooling, heat treatment and other processes. After entering the machining process, the tail end is prone to not being processed, resulting in black skin at the tail end of the steering knuckle, affecting product quality. Therefore, it is very necessary to identify deformed products in real time during the production process and isolate the problem products in time to prevent the deformed steering knuckle from flowing to the next process.

[0003] At present, the measurement and identification of steering knuckle products with tail-end deformation usually requires the use of three-coordinate scanning equipment to complete the inspection. The operator must first move the steering knuckle product to the three-coordinate scanning platform, and then complete the inspection after positioning, adjusting the equipment to find the origin, etc., which has low operating efficiency and high labor intensity. In addition, the three-coordinate scanning equipment is expensive, has a high frequency of use, and covers a limited number of products. It cannot meet the inspection and measurement of large quantities of steering knuckle products, and is prone to missed inspections and misjudgments.

[0004] Based on this, developing a steering knuckle deformation inspection fixture with simple structure, easy operation and portability for application in actual production is an urgent problem to be solved. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] like Figure 1-2 As shown, a portable inspection tool for steering knuckle deformation includes a seat plate 1, on which a positioning structure is provided corresponding to the front end of the steering knuckle product, for supporting and positioning the front end of the steering knuckle product to be inspected, and a detection structure is provided corresponding to the rear end of the steering knuckle product, for deformation detection of the steering knuckle to be inspected. The detection structure includes a detection block 2 provided corresponding to the rear end of the steering knuckle, and a detection hole 21 is provided on the detection block 2 corresponding to the shape of the rear end of the steering knuckle, so that the rear end of the steering knuckle with a standard size shape can completely fall into the detection hole 21.

[0022] When using, Figure 2 As shown, the operator places the steering knuckle product to be tested on the positioning structure and observes whether the rear end of the steering knuckle completely falls into the detection hole 21 on the detection column, which is used as a basis for determining whether the steering knuckle meets the requirements. If the rear end of the steering knuckle is deformed in the horizontal direction and / or the height direction, causing the rear end to be offset relative to the detection hole 21 and unable to completely fall into the detection hole 21, it is determined that the rear end of the steering knuckle to be tested has been deformed to affect the quality, and the steering knuckle is rejected from entering the next process; if the rear end of the steering knuckle can smoothly and completely fall into the detection hole 21, it is determined that the rear end of the steering knuckle to be tested has not been deformed, or the deformation is small and has no effect on the product quality, and the steering knuckle to be tested can enter the next process normally.

[0023] This embodiment utilizes the structural characteristics of the steering knuckle product, takes the front end of the steering knuckle that is not prone to deformation as the product detection benchmark, supports and positions it through the positioning structure of the inspection fixture, and observes whether the rear end of the steering knuckle completely falls into the detection hole 21 as the basis for judging whether the rear end of the inspected steering knuckle is deformed. It can realize the quick detection of the deformation of the steering knuckle product, so that the detection process no longer relies on the three-coordinate scanning equipment, improves the detection efficiency, and reduces the occupancy time of the three-coordinate scanning equipment. In addition, this embodiment has a simple structure, is lightweight and portable, and is convenient for operators to carry to the inspection work and carry out the inspection work at any time, which reduces the intensity of manual labor, can realize large-scale inspection, effectively eliminates the situation of missed inspection and misjudgment, and ensures product quality.

[0024] As a first embodiment, the positioning structure is a positioning seat (not shown in the figure) made according to the shape of the front end of the steering knuckle. The positioning seat is a block structure fixedly set on the seat plate 1. The top of the positioning seat is made according to the shape of the bottom of the front end of the steering knuckle, so that the top of the positioning seat can completely fit the bottom of the front end of the steering knuckle to form a positioning support for the front end of the steering knuckle. When in use, the bottom of the front end of the steering knuckle to be tested lies on the positioning seat to complete the support positioning of the steering knuckle to be tested. At this time, by observing whether the rear end of the steering knuckle completely falls into the detection hole 21 of the detection block 2, it can be determined whether the steering knuckle to be tested meets the quality requirements.

[0025] As a second embodiment, in order to reduce the overall weight of the inspection tool for easy carrying, at the same time, the positioning structure is a positioning column 3 set at several points corresponding to the front end of the steering knuckle, and the steering knuckle to be inspected is positioned and supported on the seat plate 1 through several positioning columns 3. This embodiment replaces the positioning seat structure in the first embodiment with the positioning column 3, which greatly reduces the difficulty of making the inspection tool and saves the production cost. At the same time, the overall weight of the inspection tool is reduced and the portability is improved. It also avoids the over-positioning of the positioning seat in the aforementioned embodiment, and the positioning of the front end of the steering knuckle is more accurate and the support is more stable.

[0026] Preferably, if Figure 1 As shown, the top of the positioning column 3 is provided with a positioning protrusion 31 corresponding to the positioning hole at the front end of the steering knuckle, and the bottom of the positioning protrusion 31 is connected with a positioning step 32, and the height of the positioning protrusion 31 is less than the depth of the steering knuckle positioning hole. When in use, the positioning protrusion 31 extends into the steering knuckle positioning hole, and the positioning step 32 is supported on the lower end surface of the positioning hole. In this embodiment, the positioning protrusion 31 realizes the horizontal positioning of the steering knuckle, and at the same time, the positioning step 32 can also form the positioning of the steering knuckle in the height direction, further ensuring the positioning accuracy of the steering knuckle.

[0027] Preferably, the top of the positioning column 3 corresponds to the positioning cone provided at the bottom of the front end of the steering knuckle and is provided with a positioning groove 33, and the depth of the positioning groove 33 is greater than the height of the positioning cone. When in use, the positioning cone on the steering knuckle to be tested is inserted into the positioning groove 33 to form a positioning support for the steering knuckle.

[0028] Preferably, a support column 34 is also provided on the seat plate 1 at the bottom of the front end of the steering knuckle to improve the support stability of the steering knuckle. Figure 1 As shown, a protective baffle 4 is also provided on the seat plate 1 corresponding to the detected steering knuckle, which is used to protect the detected steering knuckle from the side and prevent the detected steering knuckle from tipping over. The protective baffle 4 is arranged at a certain distance relative to the detected steering knuckle to avoid interfering with its positioning.

[0029] The above disclosure is only a specific embodiment of the present invention, but the present invention is not limited thereto.
