[0002] In the current commercial vehicle manufacturing industry, the kingpin hole position measurement of front axle components is a crucial step. This measurement ensures the quality and precision of the front axle components, directly affecting the performance and safety of the entire vehicle. As a key component of the front axle, the accuracy of the kingpin hole's position is critical to the vehicle's steering and suspension systems. If the kingpin hole's position deviates, it may lead to inflexible steering, unstable suspension, or even safety accidents. Therefore, in the commercial vehicle manufacturing process, accurately measuring the kingpin hole position of the front axle components is one of the key steps to ensure product quality and safety.

[0003] Currently, the position accuracy of the kingpin hole of the front axle workpiece is often detected by automated equipment or by manual inspection. Automated equipment, such as coordinate measuring machines, is expensive and requires professional personnel to operate. Manual inspection often relies on manual measurement, and the results are easily affected by the experience of the inspectors, resulting in poor consistency and low accuracy. Summary of the Invention

[0004] To address the shortcomings of the existing technologies, a device for detecting the position of the kingpin hole in a commercial vehicle front axle workpiece is provided. Compared with automated equipment, this device reduces enterprise costs; compared with manual inspection, it is not affected by the experience of the inspectors and improves the accuracy of the inspection.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is a device for detecting the position of the kingpin hole of a commercial vehicle front axle workpiece, including a base plate, a support frame for supporting the front axle workpiece on the base plate, a first position template and a second position template on both sides of the support frame, a positioning gauge bar on the first position template, a guide hole on the second position template, and a detection gauge bar inserted into the guide hole.

[0006] The aforementioned device for detecting the position of the kingpin hole of a commercial vehicle front axle workpiece includes a support frame comprising two brackets, on which two positioning plates are respectively provided.

[0007] The above-mentioned device for detecting the position of the kingpin hole of a front axle workpiece for a commercial vehicle includes a first plate body disposed on a base plate, a first boss having an inclined top surface on the first plate body, and a positioning gauge rod disposed on the first boss.

[0008] The above-mentioned commercial vehicle front axle workpiece kingpin hole position detection device includes a second position template comprising a second plate body disposed on a base plate, a second boss having an inclined top surface on the second plate body, and a guide hole disposed on the second boss.

[0009] The aforementioned device for detecting the position of the master pin hole of a commercial vehicle front axle workpiece has a positioning pin hole on the base plate and positioning pins that are adapted to the positioning pin hole on the first plate and the second plate.

[0010] The aforementioned device for detecting the position of the master pin hole of a commercial vehicle front axle workpiece has multiple corresponding positioning pin holes.

[0011] The beneficial effects of this utility model of a detection device for the position of the kingpin hole of a commercial vehicle front axle workpiece are that it uses a support frame and a positioning gauge to position the front axle workpiece, and realizes the detection by cooperating the detection gauge with the guide hole, which reduces enterprise costs, reduces the influence of the experience of the detection personnel, and improves the detection accuracy.

[0012] By connecting the first plate and the second plate to the base plate through positioning pins and positioning pin holes, and by setting multiple positioning pin holes, when inspecting front axle workpieces of other specifications, it is only necessary to pull out the positioning pins, manually move the first position template and the second position template to the corresponding positioning pin holes, and then insert the positioning pins to meet the inspection requirements of the front axle workpieces of that specification, thus further improving practicality.

[0014] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. Example

[0015] like Figure 1 As shown, a device for detecting the position of the kingpin hole of a commercial vehicle front axle workpiece includes a base plate 1. A support frame for supporting the front axle workpiece is provided on the base plate 1. A first position template and a second position template are respectively provided on both sides of the support frame. A positioning gauge 2 is provided on the first position template. A guide hole (not shown in the figure) is provided on the second position template. A detection gauge 3 that is inserted into the guide hole is provided in the guide hole.

[0016] The support frame includes two supports, each with two positioning plates 4. Each support consists of two parallel horizontal plates 5 and a vertical plate 6 connecting the two horizontal plates 5, forming an "I" shape. The positioning plates 4 are located on the top horizontal plate 5. The distance between the two positioning plates is adapted to the width of the front axle workpiece. That is, after the front axle workpiece is placed on the two positioning plates, the sidewall of the front axle workpiece contacts the two positioning plates. The function of the two positioning plates is to prevent displacement of the front axle workpiece.

[0017] The first position template includes a first plate 7 disposed on the base plate 1, and a first boss 8 with an inclined top surface is provided on the first plate 7. The positioning rod 2 is disposed on the first boss 8.
