In the process of braking of the conventional electric automobile, a vacuum source is often needed to assist the automobile to brake through a vacuum pump; the vacuum source required by the brake is mainly provided by a vacuum tank, external air enters the vacuum tank, and then the vacuum pump vacuumizes the vacuum tank until the negative vacuum degree in the vacuum tank is reached to assist the brake.
Most of vacuum tanks produced in the current market are shown in fig. 1, and two key inlets and outlets on the vacuum tank (10) are respectively an air nozzle (101) and a sensor hole (102). The air tap (101) is used for being connected with a vacuum brake hose, negative pressure can be pumped into the vacuum tank through the air tap (101), the sensor hole (102) is a position for installing a gas pressure sensor, and the gas pressure sensor can detect the pressure in the vacuum tank. When the size of the air nozzle (101) is out of tolerance downwards or the roundness of a boss of the air nozzle is not enough or even a gap exists, the connection failure of the air nozzle (101) and a vacuum brake hose can be caused, and air leakage can occur; when the size (102) of the sensor hole is out of tolerance, the connection failure of the sensor hole (102) and the gas pressure sensor can be caused, so that gas leakage occurs, and the gas leakage at any position can cause the brake failure of the whole vehicle, so that the consequences are very dangerous.
The partial vacuum tank on the current market adopts the HDPE material to carry out the blow molding process preparation and forms, because the vacuum tank blowing forms the back, the workman need prune deckle edge on the air cock, drills through the sensor hole simultaneously, if the mistake in operation, will lead to the size at two positions in air cock and sensor hole or the compliance of circularity can't guarantee to just probably cause vacuum tank gas leakage.
The common air tap size or roundness measuring method is to use a vernier caliper to perform multi-point measurement or directly use a roundness meter; the common detection mode of the sensor hole size is to use a vernier caliper to perform multipoint measurement or use a plurality of cylindrical plug gauges to perform detection. The method has high measurement cost or troublesome operation and low detection efficiency.

Detailed Description
The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings, wherein the embodiments of the present invention are described in detail with reference to the accompanying drawings, for example, the shapes and structures of the respective members, the mutual positions and connection relationships between the respective portions, the functions and operation principles of the respective portions, and the like.
Example 1:
this embodiment provides a quick detection frock in vacuum tank air cock and sensor hole to solve the troublesome poeration that current detection mode exists, detection efficiency low scheduling problem.
As shown in fig. 2 and 3, the vacuum tank air cock and sensor hole rapid detection tool of this embodiment includes the elastic clamp 20 that is composed of first arm lock 1, second arm lock 2, pivot 3 and torsion spring 4 swing joint, and the middle part of first arm lock 1, second arm lock 2 all is equipped with the side ear 5 of relative protrusion, side ear 5 is equipped with the through-hole, pivot 3 is worn to locate through-hole department, torsion spring 4 is around locating pivot 3, and torsion spring 4's both ends offset with first arm lock 1, second arm lock 2 respectively. The interiors of the opposite sides of the first clamping arm 1 and the second clamping arm 2 are hollow, and the end part of the torsion spring 4 is positioned in the hollow. The pressing ends of the first clamping arm 1 and the second clamping arm 2 are in a dovetail shape, the two pressing ends are pinched by force, so that the clamping ends of the two clamping arms are relatively opened, and after the pressing ends are loosened, the clamping ends of the two clamping arms can rotate oppositely to clamp due to the elastic torsion action of the torsion spring 4.
The clamping ends of the first clamping arm 1 and the second clamping arm 2 are provided with semicircular bayonets 6 with opposite opening directions, and the semicircular bayonets 6 of the two clamping arms are provided with semicircular steps 7, so that a circular stepped hole 11 formed by a first circular hole and a second circular hole is formed when the clamping ends of the two clamping arms are connected; the diameters of the first circular hole and the second circular hole are respectively equal to the lower deviation size and the upper deviation size of the air tap of the vacuum tank to be measured.
Plunger gauges are fixedly arranged on one sides, far away from the rotating shaft 3, of the first clamping arm 1 and the second clamping arm 2, wherein a first plunger gauge 8 is arranged on the first clamping arm 1, and a second plunger gauge 9 is arranged on the second clamping arm 2; the diameters of the first plunger gauge 8 and the second plunger gauge 9 are respectively equal to the upper deviation size and the lower deviation size of the sensor hole to be measured.
As shown in FIGS. 4-6, the process of detecting the air tap and the sensor hole of the vacuum tank by using the tool is as follows:
at first, utilize the elasticity of torsional spring 4, make the exposed core of first arm lock 1, second arm lock 2 clip the 10 air cocks of vacuum jar, then rotatory frock, through observing the clearance of vacuum jar air cock 101 and circular shoulder hole 11, judge whether circularity, the size meet the requirements of vacuum jar air cock 101: if the boss of the air nozzle 101 is notched or has an out-of-tolerance downward dimension, a large gap is left in the stepped hole 11 of the air nozzle 101, and the air nozzle is an unqualified product.
After having detected vacuum tank air cock 101, take off the frock from vacuum tank air cock 101 to insert first plunger gauge 8, second plunger gauge 9 respectively in the sensor hole 102 of vacuum tank 10, utilize two plunger gauges to detect whether the size in sensor hole 102 meets the requirements: if the first plug gauge 8 cannot be inserted into the sensor hole 102 and the second plug gauge 9 can be inserted into the sensor hole 102, the sensor hole 102 is qualified in size, otherwise it is not qualified.
