Detailed Description
The quick detection device for the tooth-shaped center distance of the rack of the automobile steering gear comprises a special vernier caliper 1, a positioning pin 2 and a clamping auxiliary tool 3 (see the attached figure 1 in the specification).
The clamping assistive device 3 comprises an assembly block 9, a bottom plate 10, an assembly screw 11, a locking bolt 12 and a locking block 8 (see the attached figures 4 and 5 in the specification); the middle part of the assembling block 9 is provided with a through hole 5; the width of the through hole 5 is consistent with that of the workpiece 13; the workpiece 13 can be inserted into the fitting block 9 along the through hole 5.
A locking block 8 is slidably arranged on an assembling block 9 below the through hole 5 through a guide rail; the top end of the locking block 8 is provided with a locking cambered surface 6 (see the description and the attached figure 5). The radian of the locking cambered surface 6 is consistent with that of the circumferential surface of the workpiece 13; after the workpiece 13 is inserted into the assembly block 9 along the through hole 5, the workpiece 13 can be clamped and fixed by the locking block 8 through the locking arc surface 6 in a laminating and pressing mode, and the problem that the surface of the workpiece 13 is crushed due to the fact that the contact area of the locking block 8 and the workpiece 13 is too small is avoided.
The bottom end of an assembly block 9 below the locking block 8 is fixedly provided with a bottom plate 10 through an assembly screw 11; the locking bolt 12 is installed on the bottom plate 10 in a threaded manner; the top end of the locking bolt 12 is in contact connection with the locking block 8 (see the description and the attached figure 4); during operation, when the locking bolt 12 is tightened, the locking bolt 12 can move upwards relative to the bottom plate 10 and push the locking block 8 to move upwards along the guide rail; when the locking bolt 12 is loosened, the locking block 8 can automatically move downwards under the action of gravity and is always in contact connection with the locking bolt 12 in the downward movement process of the locking bolt 12.
A positioning insertion hole (not shown in the attached drawings) is arranged on the assembling block 9 above the through hole 5; and a positioning pin 2 is movably inserted in the positioning insertion hole. The positioning pin 2 is in a step-shaped structure (see the description and the attached drawings 4 and 5);
the movable measuring jaw 4 on the special vernier caliper 1 is of an arc-shaped plate-shaped structure; the radian of the inner side cambered surface of the movable measuring jaw 4 is consistent with the radian of the thick section circumferential surface of the positioning pin 2 (see the attached figures 2 and 3 in the specification). The other component structures of the special vernier caliper 1 are consistent with those of the conventional vernier caliper 1. The purpose of setting the special vernier caliper 1 is as follows: when making the detection, the mode of accessible activity graduated flask 4 and the surface laminating contact of locating pin 2 is fixed a position activity graduated flask 4 to reach the purpose of quick accurate detection.
The assembly blocks 9 on both sides of the through hole 5 are provided with observation holes 7 (see the description and the attached figures 4 and 5). The purpose of the observation hole 7 is to: when the rapid detection device is used for detection, people can observe the condition inside the assembly block 9 through the observation hole 7, so that the detection can be carried out smoothly.
When the quick detection device is used for detecting the tooth-shaped center distance of the rack of the automobile steering gear, firstly, the assembly block 9 is inserted into a workpiece 13 through the through hole 5; then insert the dowel 2 to the location jack of assembly piece 9, see through observing hole 7 afterwards and adjust dowel 2 and assembly piece 9, make the dowel 2 insert the tooth-like central point of auto steering ware rack and put, later through the mode of tight locking bolt 12, make it promote latch segment 8 to move up together and lock work piece 13 along the guide rail, work piece 13 can keep fixed connection with joint assistor 3 like this.
