Abstract
The utility model discloses an assembly defect detection device of a vacuum booster, comprising a base, a cylindrical sleeve, a proximity sensor and a displacement sensor. The base comprises a base body and a boss which is connected with the lower surface of the base body and protrudes downwards; a central through hole which puts through the base body and the boss is arranged on the base; a side through hole is also arranged on the base body; the proximity sensor is fixedly arranged in the side through hole; the displacement sensor is fixedly arranged on the base body; and the cylindrical sleeve is sheathed outside the boss. The assembly defect detection device of the vacuum booster adopts the proximity sensor and the displacement sensor to detect the assembly defects and can greatly improve the defect relevance ratio compared with manual detection. The assembly defect detection device of the vacuum booster can also be matched with an industrial personal computer and a cylinder for use, and is convenient to achieve automatic defect detection, thereby improving the detection efficiency.
Description
Technical field
The utility model relates to a kind of pick-up unit that is used to detect the assembling defective of vacuum booster.
Background technology
Vacuum booster is the brake power assist unit in the car brake system, is the critical component in the brake system of car.Its principle of work is the vacuum that is produced when utilizing engine operation, when the driver depresses brake pedal, the thrust that is produced by the different pressures difference of two working chambers in the vacuum booster, amplify brake pedal force in proportion, brake fluid in the compression master cylinder produces hydraulic pressure, thereby drive detent hub for vehicle wheel is applied damping force, reach the effect of braking.
Vacuum booster the neglected loading of push rod plug can occur in assembling process and spring is adorned defectives such as inclined to one side, whether existing detection mode is to have the push rod plug to leak the situation of shape by magnet suction push rod plug and visual inspection, this detection mode not only has human cost height, the slow shortcoming of detection speed, and omission takes place easily, the product quality of vacuum booster is affected.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of vacuum booster assembling defect detecting device that can detect vacuum booster assembling defective easily and accurately.
The technical scheme that the utility model adopted is: a kind of vacuum booster assembling defect detecting device comprises base, cylindrical sleeves, proximity transducer and displacement transducer; The boss that base comprises pedestal and is connected and protrudes downwards with the lower surface of this pedestal; Be provided with the central through hole of a perforation pedestal and boss on this base, also be provided with a side through hole on pedestal, proximity transducer is installed in the side through hole, and displacement transducer is installed on the described pedestal; Cylindrical sleeves is set in outside the boss.
The utility model adopts proximity transducer and displacement transducer that the assembling defective is detected, and compares with manual detection, can improve the defective recall rate greatly.The utility model also can be used with industrial computer and cylinder, is convenient to realize that defective detects automatically, thereby has improved detection efficiency, has saved human cost.
Description of drawings
Fig. 1 is the structural representation of vacuum booster assembling defect detecting device of the present utility model;
Fig. 2 is the view of vacuum booster assembling defect detecting device of the present utility model when detecting;
Fig. 3 is the local enlarged diagram of Fig. 2.
Embodiment
As shown in Figure 1, vacuum booster assembling defect detecting device of the present utility model comprises base 1, cylindrical sleeves 2, proximity transducer 3 and displacement transducer 4.The boss 12 that base 1 comprises pedestal 11 and is connected and protrudes downwards with the lower surface of this pedestal 11; On this base, be provided with the central through hole 13 of a perforation pedestal 11 and boss 12, on pedestal, also be provided with a side through hole 14 (see figure 3)s.Proximity transducer 3 is installed in the side through hole 12, and displacement transducer 4 is installed on the pedestal 11.Preferably, side through hole 12 is a threaded hole, and proximity transducer 3 is threaded with this threaded hole.Cylindrical sleeves 2 is set in outside the boss 12.
Link to each other with cylinder for the ease of vacuum booster assembling defect detecting device of the present utility model, this vacuum booster assembling defect detecting device also is provided with a supporting base 5 and three support columns 6.The lower end of three support columns 6 is arranged on the upper surface of pedestal 11, and the upper end links to each other with supporting base 5.
Fig. 2 and Fig. 3 show the synoptic diagram of vacuum booster assembling defect detecting device of the present utility model when detecting.When detecting, cylindrical sleeves 2 extend in the spring 71 of vacuum booster 7, and contacts with the inwall of this spring 71.Cylindrical sleeves 2 of the present utility model is convenient to change, to adapt to the spring of different size.The material of this cylindrical sleeves can be selected nylon for use.The push rod plug 72 of vacuum booster 7 stretches in the central through hole 13 from the below of the central through hole 13 of base 1, and simultaneously, the probe 41 of displacement transducer 4 extend in the central through hole 13 from the top of the central through hole 13 of base 1, and this central through hole 13 can be made as ladder hole.Proximity transducer 3 detects the housing 73 and the distance L 1 between this proximity transducer 3 of vacuum boosters 1, adorns when inclined to one side when spring 71, and cylindrical sleeves 2 can't normally extend in the spring 71, cause distance L 1 above normal value.The distance L 2 that displacement transducer 4 detects between push rod plug 72 and this displacement transducer 4 when the push rod plug leaks shape or correctly do not install, can cause the testing result deviation very big.By supporting base 5 of the present utility model is linked to each other with cylinder, simultaneously proximity transducer 3 of the present utility model is linked to each other with industrial computer with displacement transducer 4, by software, can realize the full-automatic detection of vacuum booster assembling defective, and can preserve the detection data, thereby greatly improved detection efficiency and defective recall rate, guaranteed product quality.
