Abstract
Description
Technical Field
[0001] The utility model belongs to the field of vacuum booster assembly detection machinery, in particular to a universal booster height detection device. Background Art
[0002] The booster is a component that uses hydraulic pressure, air pressure, vacuum (negative pressure) or electrical energy to increase the force applied by the driver to the pedal. Currently, boosters include air boosters, vacuum boosters, electric boosters, hydraulic boosters, etc. The vacuum booster assembly is a key component in the automobile braking system. Its main function is to amplify the servo force through the vacuum booster through the pedal force, acting on the brake master cylinder, causing it to move forward to compress the brake fluid in the master cylinder, and then deliver hydraulic pressure to the brake system of the entire vehicle through the brake master cylinder oil outlet, thereby realizing the braking function of the vehicle.
[0003] With the increase in automobile models, customers have higher and higher requirements for brake feel. The OEM will change the parameters or size of the booster according to the actual situation. Trial products are generally small in number, and the production line needs to be adjusted, which wastes time. At the same time, occupying the production line will cause delays in product delivery. In order to solve this problem, a new trial production line has been added, which is specially used to produce trial products. Since the adjustment fork heights and types of trial products vary, measuring tools of various heights are required. In order to facilitate production, it is necessary to develop a universal device that can detect the height of the adjustment fork to ensure the loading size. Summary of the invention
[0004] The utility model provides a universal height detection device for a booster, which can be suitable for detecting the height dimensions of boosters of different specifications.
[0005] The technical solution adopted by the utility model is that it includes a measuring shaft, a guide sleeve, a slider, a support pad, bolts, a bracket, bolts and a base, wherein the bracket is fixed to the base by bolts, the guide sleeve is embedded in the slider by interference fit, the upper part of the bracket is located in the slideway of the slider, the slider is fixed to the bracket by a support pad and bolts, and the measuring shaft is plugged into the guide sleeve.
[0006] The slide block is provided with a positioning surface, the height of which is flush with the center of the measuring axis.
[0007] The bracket is provided with 5 threaded holes at different heights.
[0008] The base is provided with a concave shape to give way.
[0009] The utility model has the advantages of novel structure. After the position of the slider on the bracket is calibrated with a height gauge, the threaded hole at the appropriate position on the bracket is selected to ensure the stability and verticality of the slider, and can be adapted to boosters of different heights; the concave shape on the base makes way for boosters with different specifications of screw distances, without replacing different bases; the measuring shaft can be removed at any time and replaced according to different adjustment fork types, without investing a set of height measuring tools for each type, and will not cause waste in cost. The utility model is applied to the general height detection of vacuum boosters of higher-end cars and micro cars during the trial production process. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 4 It is a schematic diagram of the working state of the utility model. DETAILED DESCRIPTION
[0014] like Figure 1 As shown, it includes a measuring shaft 1, a guide sleeve 2, a slider 3, a support pad 4, a bolt 5, a bracket 6, a bolt 7 and a base 8, wherein the bracket 6 is fixed to the base 8 by the bolt 7, the guide sleeve 2 is embedded in the slider 3 by interference fit, the upper part of the bracket 6 is located in the slideway 301 of the slider 3, the slider 3 is fixed to the bracket 6 by the support pad 4 and the bolt 5, and the measuring shaft 1 is plugged into the guide sleeve 2.
[0015] like Figure 2 As shown, the slider 3 has a positioning surface 302, and its height is flush with the center of the measuring axis 1. The position of the slider 3 on the bracket 6 can be adjusted by a height gauge to make the height reach the required size of the product.
[0016] like Figure 2 As shown, the bracket 6 has five threaded holes 601 at different heights, which facilitates the adjustment of the height size.
[0017] like Figure 3 As shown, there is a concave recess 801 on the base 8, so that the measuring tool can be used for boosters of different specifications.
[0018] When working, Figure 4As shown, there is a positioning surface 302 on the slider 3, and its height is flush with the center of the measuring shaft 1. The position of the slider 3 on the bracket 6 can be adjusted by a height gauge to make the height reach the required size of the product. First, according to the height dimension L required by the booster assembly 9, the position of the slider 3 on the bracket 6 is calibrated with a height gauge, and then fixed to the bracket 6 through the support pad 4 and the bolt 5, and the threaded hole 601 at the appropriate position on the bracket 6 is selected to ensure the stability and verticality of the slider 3. The appropriate measuring shaft 1 is selected, and then the base 8 is placed on the end surface of the rear shell of the vacuum booster assembly. The concave position 801 on the base 8 can adapt to the vacuum booster assembly with different specifications of screw distances. The thin end of the measuring shaft 1 is inserted into the hole of the vacuum booster assembly adjustment fork 901. The screwing height of the adjustment fork 901 is adjusted so that the measuring shaft 1 can pass smoothly, proving that the height adjustment is qualified. The nut 902 and the adjustment fork are tightened with a torque wrench to complete the adjustment and detection process of the height dimension of the adjustment fork.
