Description

Technical Field

[0001] The utility model relates to the technical field of steering knuckle detection, in particular to a comprehensive steering knuckle detection tool. Background Art

[0002] The steering knuckle, also known as the "knuckle," is a core component in a vehicle's steering system. Its primary function is to transmit and bear the front load, supporting and driving the front wheels around the kingpin to steer the vehicle. To ensure the safety and performance of the vehicle's steering system, the steering knuckle must be inspected. However, existing techniques require the use of three different gauges to inspect the front portion of the knuckle, as the front portion is a cylinder of varying sizes with decreasing diameters. This results in low inspection efficiency.

[0003] In response to the above problems, the patent document with authorization announcement number CN219265169U discloses a steering knuckle inspection fixture, which is provided with an inspection port for placing the steering knuckle to be inspected and an observation port connected to the inspection port on the inspection platform. The inspection port is composed of three through holes with decreasing apertures. The observation port is used to observe the inside of the inspection port. The inspection platform is also provided with a mounting assembly, which is connected to the inspection platform for installing the inspection platform. When in use, the steering knuckle can be observed to see whether it can be placed in the inspection port, and the matching condition of the steering knuckle placed in the inspection port and the inspection port can be observed through the observation port, thereby completing the inspection of the steering knuckle.

[0004] It can be seen that the above-mentioned inspection fixture completes the inspection of the steering knuckle by observing whether the steering knuckle can be inserted into the inspection port and whether the inserted steering knuckle matches the inspection port. It can test the three radial and axial dimensions of the steering knuckle at a time, which improves inspection efficiency. However, the above-mentioned inspection fixture can only test the front part of the steering knuckle and cannot test the entire steering knuckle. The steering knuckle must be disassembled and reassembled multiple times to test different parts, which increases inspection time and labor costs. Utility Model Content

[0005] The utility model provides a comprehensive steering knuckle inspection tool to solve the technical problem in the prior art that the inspection range of the steering knuckle inspection tool is limited, which leads to increased time and labor costs for steering knuckle inspection.

[0006] In order to solve the above problems, the steering knuckle comprehensive inspection fixture provided by the present invention adopts the following technical solutions:

[0007] A comprehensive inspection tool for a steering knuckle, comprising a base and:

[0011] a third detection assembly, which is disposed on the base and located between the first detection assembly and the second detection assembly, the third detection assembly comprising a third detection seat and a third detection pin extending vertically and mounted on the third detection seat;

[0012] The fourth detection assembly is arranged on the base and is located on the side of the positioning column away from the third detection assembly. The fourth detection assembly includes a fourth detection seat and a fourth detection pin obliquely installed on the fourth detection seat.

[0013] The beneficial effects of the steering knuckle comprehensive inspection fixture provided by the present invention are as follows: by providing a positioning component and arranging the inspection component on the periphery of the positioning component, when the steering knuckle to be measured is placed, the positioning component can be used to achieve the purpose of self-centering of the steering knuckle to be measured; by providing four groups of inspection components on the periphery of the positioning component, the dimensions of various parts of the steering knuckle to be measured can be accurately measured, the inspection range is wider, and all-round measurement of the steering knuckle dimensions can be achieved by only one inspection fixture, which greatly improves the inspection efficiency of the steering knuckle, thereby reducing the labor cost caused by the long inspection time of the steering knuckle.

[0014] Through the above arrangement, the utility model effectively solves the technical problem in the prior art that the detection range of the steering knuckle inspection fixture is limited, which leads to increased time and labor costs for steering knuckle inspection.

[0015] Furthermore, an obliquely arranged fifth detection assembly is provided between the second detection assembly and the fourth detection assembly. The fifth detection assembly includes a fifth detection seat installed on the base, and a fifth detection pin extending vertically is installed on the fifth detection seat.

[0020] Furthermore, the guide section of the tapered detection pin is a variable diameter structure, and its radial dimension decreases sequentially from the first detection seat to the positioning column, so as to be used for positioning the variable diameter section of the steering knuckle to be tested.

[0021] Furthermore, the number of the positioning holes is nine, and the nine positioning holes are divided into three layers and distributed radially, with the innermost layer having one positioning hole, and the middle layer and the outermost layer each having four positioning holes evenly spaced apart.

[0022] Furthermore, the number of the first detection pins is four, and the four first detection pins are divided into two groups, with two pins in each group being arranged on opposite sides of the tapered detection pin.
