The power of the engine is transmitted to the wheels through the movable end section, the intermediate shaft and the fixed end section, so that the wheels are driven to rotate. The fixed end section mainly comprises a bell-shaped shell, a star-shaped sleeve, a retainer and a steel ball. In a high-performance transmission shaft with high transmission efficiency, large swing angle, light weight and low noise, eight inner ball paths are arranged on a bell-shaped shell of a fixed end joint, and each ball path consists of two circular arc sections with different curvatures and a straight line section in sequence; the bell-shaped shell of the type requires that the distance between diameters corresponding to the center points of the ball tracks is measured and grouped, so that the bell-shaped shell is matched with steel balls with corresponding sizes and an eight-ball-track star sleeve to be assembled, and the reasonable clearance among the parts is ensured. The diameter corresponding to the center of the ball path of the eight-ball-path bell-shaped shell is crucial to the performance influence of the fixed end joint, if the diameter corresponding to the center of the ball path of the bell-shaped shell is measured inaccurately, the assembled fixed end joint is unqualified in function test after assembly, the problems of low transmission efficiency, serious abrasion, short service life and the like can occur, even the assembly problems of clamping stagnation, abnormal sound, small swing angle and the like of the fixed end joint occur when a host factory is off-line, the risk of stopping or calling back of the host factory exists, and the satisfaction degree of users is reduced.
The conventional method for detecting the ball track center distance of the eight-ball track bell-shaped shell adopts three-coordinate detection, a single product needs to be detected for at least 15 minutes, the detection efficiency is extremely low, the problems of bell-shaped shell production stop line caused by accumulation of products to be detected and transmission shaft assembly line missing stop line caused by low detection efficiency often occur, and if a sampling detection mode is adopted, the quality risk of ex-factory off-line of unqualified products exists; if the transmission shaft is tested after assembly to find a unqualified bell-shaped shell, the unqualified transmission shaft fixing end joint is disassembled, the eight-ball-channel bell-shaped shell is replaced, and the eight-ball-channel bell-shaped shell matched with the star-shaped sleeve is selected for assembly to meet the requirements of the fixed end joint on rolling moment, swinging moment and axial clearance. The qualified bell-shaped shell is reselected for assembly, so that the assembly efficiency of the transmission shaft is low, parts such as a clamp, a steel ball, lubricating grease, a rubber cover and the like of the fixed end section are completely scrapped after disassembly, the serious waste of materials and materials is caused, and the production cost is increased; once the transmission shaft with the unqualified eight-lane bell-shaped shell is delivered to a user side, abnormal sound occurs after the transmission shaft is used for a period of time, and even the transmission shaft is assembled on the site of the user, the phenomenon that the host machine plant is stopped due to incapability of assembling occurs, so that the user returns goods or claims for claim, and huge loss is caused to a unit.
Therefore, an automatic device capable of detecting and grouping the ball track center distance is urgently needed in an eight-ball-track bell-shaped shell processing field to replace a three-coordinate detection method with low efficiency, so that the eight-ball-track bell-shaped shell can meet the harsh requirement of rapidly detecting and grouping piece by piece along with a production line.
