Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile axles, in particular to a quick inspection tool for an upper reaction rod bracket, which is a special quick inspection tool for inspecting whether the upper and lower reaction rod brackets of an axle housing have interference problems when being installed with the axle housing. Background Art
[0002] With the increase in the number of modified axle products, the reaction rod brackets of modified axle shells are also of various types and sizes. The design of these modified brackets is based on the size parameters provided by the main engine manufacturer. During the design, only the loading connection dimensions related to the whole vehicle are considered, and the external dimensions of the axle shell (half shell) actually produced by the bridge factory are rarely considered. The designed bracket holes and the bracket arc surface have large size tolerances, and it is easy for batch brackets to not match the arc surface of the axle shell during actual production. At present, when detecting the size of this position on the upper reaction rod bracket, only three-coordinate and other equipment can be used for measurement. The measurement cost is high, the time is long, and it is impossible to achieve rapid batch inspection, and the labor intensity of the inspectors is high. Utility Model Content
[0003] The utility model aims to overcome the shortcomings of the existing rapid batch detection technology and provide a rapid detection fixture for an upper reaction rod bracket, mainly solving the problem that the existing detection means cannot perform rapid batch detection.
[0004] The technical solution provided by the utility model is: a quick inspection fixture of an upper reaction rod bracket, which is special in that it consists of a base plate, a stand, a pad, a latch, a latch sleeve, and a positioning seat; the stand and the positioning seat are arranged on the base plate, and a pad is arranged between the base plate and the positioning seat; a latch and a latch sleeve are arranged on the upper part of the stand, the latch is located in the latch sleeve, and the latch sleeve and the stand have an interference fit.
[0005] Furthermore, the stand is mounted on the base plate via a first positioning pin and a second hexagon socket bolt.
[0006] Furthermore, a positioning seat is installed on the base plate through a second positioning pin and a first hexagon socket bolt.
[0007] Furthermore, the stand is composed of a stand plate, a stand bottom plate and a stand rib plate; the stand plate is provided at one end of the stand bottom plate, and the other end of the stand bottom plate and the top end of the stand plate are respectively connected to the two ends of the stand rib plate.
[0008] The beneficial effects of the utility model are as follows: 1. It is suitable for detecting the position and size of the reaction rod bracket hole on the vehicle axle and the arc surface of the bridge housing, and the measurement is simple, saving time and effort, and reducing the labor intensity of the detection personnel; 2. It can achieve batch rapid detection and save detection costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] For better understanding and implementation, the present invention is described in detail below with reference to the accompanying drawings; the embodiments are only used to explain the present invention and are not used to limit the scope of the present invention.
[0015] like Figure 1 , 2 , 3, and 4, a quick inspection fixture for an upper reaction rod bracket is composed of a base plate 1, a seat 2, a pad 3, a latch 4, a latch sleeve 5, a first positioning pin 6, a positioning seat 7, a second positioning pin 8, a first hexagon socket bolt 9, and a second hexagon socket bolt 10; the seat 2 is composed of a seat plate 2-1, a seat base plate 2-2, and a seat rib plate 2-3, one end of the seat base plate 2-2 is fixedly mounted on the seat plate 2-1, and the two ends of the seat rib plate 2-3 are respectively connected to the other end of the seat base plate 2-2 and the seat plate 2-1. Top end; use the first locating pin 6 and the second hexagon socket bolt 10 to install the stand 2 on the base plate 1, and then use the second locating pin 8 and the first hexagon socket bolt 9 to install the locating seat 7 on the base plate 1; the stand 2 and the locating seat 7 are installed on the base plate 1 in parallel, and the positions of the stand 2 and the locating seat 7 on the base plate 1 are determined by the width of the reaction rod; install the pad 3 between the base plate 1 and the locating seat 7; install the latch 4 and the latch sleeve 5 on the upper part of the stand 2, the latch 4 is located in the latch sleeve 5, and the latch sleeve 5 and the stand 2 are interference fit.
[0016] The utility model discloses a quick inspection tool for an upper reaction rod bracket, which is used for detecting the position size of the reaction rod bracket hole and the arc surface of the bridge shell on the vehicle axle. The specific use steps are as follows: the upper reaction rod bracket to be tested is placed on the positioning seat 7, and the latch 4 is used to insert the upper reaction rod bracket hole. If the latch 4 fails to be inserted into the upper reaction rod bracket hole or there is a gap exceeding the design size between the arc surface of the upper reaction rod and the positioning seat 7 after the latch 4 is inserted, it can be considered that the position size of the upper reaction rod bracket hole to be tested and the arc surface of the upper reaction rod is out of tolerance, and the tested reaction rod bracket is unqualified; if there is no such situation, it is considered that the tested upper reaction rod bracket is qualified. The inspection tool can quickly detect whether the upper reaction rod bracket is qualified or not, and the quick inspection tool can batch test the qualified rate of the upper reaction rod bracket; the inspection tool is easy to make, low in cost, light in weight, convenient to carry and use, simple to operate when in use, and suitable for actual production.
