Abstract
Description
Technical Field
[0001] This utility model relates to a testing device for measuring the coaxiality of the end hole of a stabilizer bar, belonging to the field of stabilizer bar testing technology. Background Technology
[0002] The stabilizer bar, also known as an anti-roll bar or balance bar, is a crucial component of a car's suspension system. Its core function is to suppress body roll during cornering or driving on uneven surfaces, thereby improving vehicle handling stability and driving safety. After the bushings are installed, the stabilizer bar needs to be assembled with other components of the car's suspension. The quality of the coaxiality tolerance of the stabilizer bar's end holes determines the ease of the assembly process; therefore, the coaxiality of the end holes on both sides of the stabilizer bar must be tested before it leaves the factory.
[0003] The existing main method for measuring the coaxiality of the holes at both ends of a stabilizer bar is to use equipment such as a coordinate measuring machine (CMM) scanner to scan the bar as a whole and then calculate the coaxiality tolerance between the holes at both ends. However, the CMM scanning method is limited by the measurement location and time, resulting in low detection efficiency and making it unsuitable for the inspection of large batches of products. Utility Model Content

[0005] The detection device for measuring the coaxiality of the end hole of the stabilizer bar described in this utility model includes a crossbeam, with a detection end block A at one end of the crossbeam and a detection end block B at the other end of the crossbeam. Both detection end block A and detection end block B are cylindrical and coaxial. The outer diameter of detection end block A and detection end block B is adapted to the size of the end hole of the stabilizer bar.
[0006] The technical solution of this utility model is to provide a detection device for measuring the coaxiality of the end holes of a stabilizer bar. When in use, it is observed whether the detection end block A and the detection end block B can be inserted into the end holes on both sides of the stabilizer bar at the same time, so as to quickly detect whether the coaxiality of the end holes of the stabilizer bar meets the standard and improve the detection efficiency.
[0007] Preferably, the axial distance between the detection end block A and the detection end block B is equal to the axial distance between the holes at both ends of the stabilizer rod.
[0008] Preferably, the outer end face of the detection end block A is chamfered to facilitate insertion into the end hole of the stabilizing rod during detection.
[0009] Preferably, the outer end face of the detection block B is provided with a handle for easy gripping and operation.
[0010] Preferably, the device is made of metal, and the detection end block A, detection end block B and crossbeam are manufactured as a whole by CNC lathe.
[0011] The advantages of this utility model compared with the prior art are:
[0012] The detection device for measuring the coaxiality of the end holes of the stabilizer bar described in this utility model can quickly detect whether the coaxiality of the end holes of the stabilizer bar meets the standard by observing whether the detection end block A and the detection end block B can be inserted into the end holes on both sides of the stabilizer bar.

[0016] The present invention will be further described below with reference to specific embodiments.
[0017] However, the description of this utility model is only a structural or even functional description of the embodiments, and the scope of the present utility model is not limited by the embodiments described herein.
[0018] For example, multiple embodiments may have various modifications and forms, and it should be understood that the scope of this utility model includes equivalents that can realize the technical concept.
[0019] like Figures 1-2 As shown, this embodiment is achieved through the following technical solution: it includes a crossbeam 2, one end of which is provided with a detection end block A4, and the other end of which is provided with a detection end block B5. Both the detection end block A4 and the detection end block B5 are cylindrical and coaxial; the outer diameter of the detection end block A4 and the detection end block B5 is used to match the end hole size of the stabilizer rod 6.
[0020] In this embodiment, the axial distance between the detection end block A4 and the detection end block B5 is equal to the axial distance between the holes at both ends of the stabilizer rod 6. The outer end face of the detection end block A4 has a chamfer 3 to facilitate insertion into the end hole of the stabilizer rod 6 during testing. The outer end face of the detection end block B5 has a handle 1 for easy gripping and operation. This device is made of metal, and the detection end block A4, detection end block B5, and crossbeam 2 are integrally machined using a CNC lathe.
[0021] The method of using this utility model is as follows:
[0022] 1. When measuring the coaxiality of the end holes of stabilizer bar 6, use a clamp to hold and fix stabilizer bar 6;
[0023] 2. Hold handle 1 with one hand and support crossbeam 2 with the other hand. Insert the detection end block A4 into the end hole on one side of the stabilizer rod 6 until the detection end block B5 is inserted into the end hole on the same side of the stabilizer rod 6.
[0024] 3. Observe whether the test end block A4 can be inserted into the other end hole of the stabilizer rod 6; if the test end block A4 cannot be inserted into the end hole, the coaxiality of the two end holes of the stabilizer rod is unqualified; if the test end block A4 can be inserted into the end hole, the coaxiality of the two end holes of the stabilizer rod is qualified.
[0025] Of course, the above description is only a preferred embodiment of this utility model and should not be considered as limiting the scope of the embodiments of this utility model. This utility model is not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of this utility model should be included in the patent coverage of this utility model.
