Description

Engine support connecting shaft bearing hole aperture and position degree detection device

Technical Field

The invention relates to the technical field of product quality detection, in particular to a device for detecting the aperture and the position degree of a bearing hole of a connecting shaft of an engine bracket.

Background

The universal drive generally consists of a universal joint, a drive shaft and an intermediate support bearing. The universal transmission device is a device for transmitting power, and has the function of connecting a transmission output shaft and a main speed reducer input shaft which are not on the same straight line, and ensuring that the power can be reliably transmitted under the condition that the included angle and the distance between the two shafts are constantly changed. The intermediate support bearing is composed of a rubber elastic element, a bearing, and the like. Because the honeycomb rubber pad has elasticity, the displacement effect caused by the compensation of installation errors, engine movement and frame deformation during running can be satisfied. The universal joint mainly comprises universal joint forks, a cross shaft, a bearing sleeve and the like. The transmission shaft is an important part for transmitting power in the transmission system of the automobile, and the transmission shaft and the drive axle together transmit the power of the engine to wheels so that the automobile generates driving force. The bearing of the transmission shaft of the engine has the functions of supporting the crankshaft, ensuring normal operation and power output of the crankshaft, better driving the automobile and ensuring the kinetic energy of the automobile. The drive shaft is a rotating body with high rotation speed and less support, so that the dynamic balance of the drive shaft is important. The dynamic balance test is carried out on the common transmission shaft before delivery, and the dynamic balance test is adjusted on a balancing machine. For front engine rear wheel drive vehicles, the transmission rotation is transmitted to the axle of the main speed reducer, which can be in several sections, and the sections can be connected by universal joints. The deviation of the ball diameter and the position degree of the universal joint bearing can cause the transmission device to make a sound of bang when the automobile starts or the speed of the automobile changes suddenly; when the automobile slows down, the transmission device makes a sound of 'Guala' and 'Guala'. In addition, the transmission shaft makes periodic sounds in the running process of the automobile; the faster the vehicle speed is, the larger the sound is, and the buffeting of the vehicle body occurs when the vehicle speed is serious, and even the hand holding the steering wheel has paralyzed feeling. Because the processing difficulty of the inner spherical surface is high, the offset condition is easy to occur, and the sphere diameter and the position degree of the inner spherical surface are required to be detected, namely, the distance between the sphere center of the inner spherical surface and the reference plane is detected, so that unqualified products are prevented from flowing to clients. At present, the device special for detecting the ball diameter and the position degree of the bearing hole of the transmission shaft of the engine is fewer, so that the detection is difficult and misjudgment is easy to occur.
