Abstract
The utility model discloses a detection tool for a brake drum. The detection tool for the brake drum adopts the technical scheme that the detection tool for the brake drum comprises a dial indicator and a support, wherein the dial indicator is mounted at the upper part of the support; the lower part of the dial indicator pushes against a bump; a spring is mounted at the lower part of the bump; a sliding block is mounted at the bottom of the spring and penetrates out of a hole that is formed in the support; a measuring head is mounted at the end part of the sliding block; and a fixed pin is mounted in the middle of the support. The detection tool is reasonable in structure and convenient to use, can detect the precision of an internal friction face of the brake drum accurately, and is better in use effect.
Description
Technical field:
The utility model relates to cubing, particularly a kind of cubing that is applicable to measure rubbing surface precision in the brake drum.
Background technology:
The brake drum that automobile is used is one of accessory of vehicle safety performance assurance, and the precision of the interior rubbing surface of brake drum is directly connected to the brake efficiency of automobile, wherein a topmost precision is jerk value, if damping force is unstable during bad will the braking of jerk value control, pine is delivered to above the brake pedal by brake piping when time between brake drum and the brake-shoe is tight, makes the driver feel pedal shake, uncomfortable, also make sound with braking simultaneously.How measuring fast the jerk value of the internal friction face of a brake drum by a cubing, is the technical matters that brake drum manufacturer is badly in need of solving.
Summary of the invention:
The purpose of this utility model be design a kind of easy to use, detect accurately brake drum cubing.
The technical solution of the utility model is, a kind of brake drum cubing, it comprises dial gauge, and support is characterized in that: on support top dial gauge is housed, projection is withstood in the bottom of dial gauge, the bottom of projection is equipped with spring, and the bottom of spring is equipped with slide block, and slide block passes from the hole that support is provided with, end at slide block is equipped with measuring head, in mid-stent fixed pin is installed.
The utility model is rational in infrastructure, and is easy to use, can be accurately the precision of the interior rubbing surface of brake drum be detected, and result of use is better.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Describe by reference to the accompanying drawings embodiment in detail, a kind of brake drum cubing, it comprises dial gauge 1, and support 2 is equipped with dial gauge on support top, the bottom end of probe of dial gauge is withstood projection 8, the bottom of projection is equipped with spring 3, and the bottom of spring is equipped with slide block 4, and slide block passes from the hole that support is provided with, in the end of slide block measuring head 5 is installed, in mid-stent fixed pin 7 is installed.The utility model in use, the center pit of brake drum 6 is placed on the fixed pin, and the inwall of brake drum can be pushed down measuring head, and measuring head is by slide block and spring, with force feedback to projection, projection withstands the bottom end of probe of dial gauge, can produce a reading at dial gauge, and brake drum is rotated a circle around fixed pin, note observing the numerical value change of dial gauge, just can know whether the interior rubbing surface of brake drum meets the accuracy requirement of processing, detection speed is quick, accurate, and result of use is better.
