Description
Technical Field
The utility model relates to a wheel hub automatic assembly line field mainly relates to a wheel hub automatic assembly detects production line.
Background
The wheel hub is a cylindrical metal part with the center arranged on the shaft and used for supporting the tire by the inner contour of the tire, so that the wheel hub is an indispensable part for automobile parts, the demand is large, along with the development of automation function, the assembly is also formed by the previous multi-process manual assembly and detection, and the automatic assembly detection of an automatic production line is developed.
The automation degree is reduced, and the cooperation operation of a specially-assigned person is as follows:
when the existing upper and lower bearings are loaded, a circular conveying mode is adopted, although the requirement of conveying and feeding is met, the bearings need to be detected before conveying, and then are placed on a circular conveying line for conveying after detection, the external detection operation needs manual material taking and placing operation, the operation is complex, the manual labor intensity is increased, time and labor are wasted, the efficiency is low, the existing circular conveying line mostly adopts a structure of a circular conveying belt or a circular conveying chain, the positioning is inaccurate, only a conveying mode is adopted, manual auxiliary loading is also needed, and the automation degree is reduced; and the clamp spring and the sealing ring between the upper bearing and the lower bearing need to be assembled in advance before press fitting, the assembly process adopts two lines for separately feeding, the two branch lines and other auxiliary mechanisms need to be matched, two material taking and placing mechanisms are also needed during assembly, the cost of equipment is invisibly increased, the assembly lines have too many branches, a large amount of space is occupied, special persons are needed for matching operation, and the manual participation factor is large.
The oil seals of the upper bearing and the lower bearing are pressed on the same station, the oil seals of the upper bearing and the lower bearing are placed in opposite directions, the lower bearing oil seal is placed at first during operation, after the hub is conveyed and aligned, the upper bearing oil seal is placed at the upper end of the upper bearing, the operation process is complex, manual work is easy to misplace, the upper bearing oil seal needs to be disassembled and assembled again, and the assembling efficiency and the assembling quality are affected.
In the existing gear ring press-fitting operation, the gear ring is placed on a wheel hub after press-fitting through special operation, then press-fitting is carried out under the action of a press-fitting machine of a gear ring press-fitting station, special people are required to take materials and feed materials for matching in the process, the labor intensity is high, time and labor are wasted, the automation degree is low, and when the gear ring is placed manually, deviation easily occurs in the position of the gear ring press-fitting machine, so that the press-fitting effect is influenced, and the press-fitting quality cannot be guaranteed.
In the existing bolt press-fitting mechanism, integral press-fitting or single-head press-fitting is usually adopted, although the integral structure can realize the press-fitting effect, the press-fitting effect of the bolts is influenced due to uneven stress distribution easily caused by different matching degrees of the bolts and bolt holes, although the single-head press-fitting can ensure that each bolt is stressed and pressed, the press-fitting operation is troublesome, the working efficiency is low, the assembly efficiency is influenced, and the phenomenon that the press-fitting process is unstable easily caused by the single-head press-fitting, so that the press-fitting quality of products is influenced; and the bolt material loading is mostly through artifical direct feeding, easy operation like this, the bolt of artifical take the position of direct insertion wheel hub bolt hole can, but the manual labor intensity is big, wastes time and energy, needs special person's operation in the production line, has increased the hand labor cost, and manual operation work efficiency is low moreover, needs to get material and blowing operation at every turn, can not satisfy the requirement of batch automated assembly production.
To sum up several simple artifical material loading or complementary unit set up unreasonable cooperation, and the in-process needs the special messenger to get the material and material loading cooperation, and artifical intensity of labour is big, wastes time and energy, and degree of automation is end, and when the manual work was placed in addition, its position appears the deviation easily to influence the pressure equipment effect, can not guarantee the pressure equipment quality, influence normal batch assembly production qualified piece volume, can not satisfy the requirement of big automated production in batches.
