In the figure: 1. the measuring head comprises a through end part, 2, a stop end part, 3, a fastening screw, 4, an installation column, 5, a right support column, 6, a stop end measuring head, 7, an anti-skidding line, 8, an installation hole, 9, a connection column head, 10, a left support column, 11 and a through end measuring head.
Detailed Description
This a detachable plug gage for rack and pinion formula steering gear casing detects comprises logical tip 1, only tip 2 and fastening screw 3, ends tip 2 and comprises erection column 4, right branch dagger 5 and only end gauge head 6, and right branch dagger 5 is prismatic, and right branch dagger 5 is used for providing the installation basis, makes this plug gage be in straight state simultaneously, reduces measuring error.
An installation column 4 is fixedly installed at one end of the right support column 5, anti-skid grains 7 are arranged on the installation column 4, and the anti-skid grains 7 are used for increasing the friction force of the installation column 4 and preventing a user from slipping hands during measurement; the end face of the mounting column 4 is provided with a mounting hole 8, and the mounting hole 8 is used for connecting the through end part 1.
The other end of right branch dagger 5 is equipped with end gauge head 6 admittedly, and end gauge head 6 is the reducing cylindricality, and the minor diameter end and the right branch dagger 5 fixed connection of end gauge head 6, the major diameter end of end gauge head 6 then are used for carrying out measurement work, when measuring the pilot hole on the rack and pinion steering gear casing, if lead to tip 1 can be through the pilot hole on the casing, and the major diameter end of end gauge head 6 can't pass through the pilot hole, then explain this pilot hole size is qualified.
A plurality of fastening screws 3 are installed on the end stopping part 2 on the outer side of the installation hole 8 in a threaded mode, the fastening screws 3 are in contact connection with the connecting column head 9, and the fastening screws 3 are used for increasing the friction force between the connecting column head 9 and the installation hole 8, so that the end stopping part 1 cannot be separated from the end stopping part 2, and the function of axial limiting is achieved.
Other end head of left branch dagger 10 is equipped with admittedly leads to end gauge head 11, it is the reducing cylindricality to lead to end gauge head 11, the path end and the left branch dagger 10 fixed connection that lead to end gauge head 11, the path end that leads to end gauge head 11 then is used for carrying out measurement work, and the diameter that should lead to end gauge head 11 path end is less than the diameter that ends 6 path ends, when measuring the pilot hole on the rack and pinion steering gear casing, the path end that leads to end gauge head 11 can enter into the pilot hole on the casing, and can produce the friction with the pore wall of pilot hole, when lead to end gauge head 11 and produce excessive loss, measuring error then can appear, can't continue to use, need change whole logical tip 1 this moment.
The working process of the detachable plug gauge for detecting the gear rack type steering gear shell is as follows: the plug gauge with the proper size is selected according to the aperture of the assembly hole, then the through end portion 1 of the plug gauge is placed in the assembly hole, the plug gauge is pushed slowly, and if the assembly hole enables the through end portion 1 of the plug gauge to pass through but the stop end portion 2 of the plug gauge not to pass through, the accuracy of the assembly hole is up to the standard.
In this testing process, the logical end gauge head 11 of feeler gauge produces the friction with the pore wall of pilot hole easily, and after long-term the use, the logical end gauge head 11 of feeler gauge weares and teares gradually makes the precision reduce, need change whole leading to tip 1 this moment, specifically do: the fastening screw 3 is rotated to draw the through end portion 1 out of the mounting hole 8, and then a new through end portion 1 is inserted into the mounting hole 8, and the fastening screw 3 is tightened again. Since the axial length of the through end portion 1 is shorter than that of the end portion 2, the volume is smaller, and therefore the replacement cost is reduced.
