Description
Technical Field
The utility model relates to a press technical field, concretely relates to axle bed mounting structure before press.
Background
The open press is generally a crank press, and is a mechanically driven forging press, and the motion and energy of a motor are transmitted to a working mechanism through a transmission system, so that the blank is stable in shape, high in working precision, good in operating condition, high in production rate, easy to realize mechanization and automation, suitable for automatic on-line work, and widely applied to industrial mechanical presses of automobiles, ships and the like.
The requirement for the part installation mode and the problem of single part processing is extremely high in the transmission motion process, the front shaft seat is one of transmission device parts, the front shaft seat in the traditional press machine is simple in structure, and the main purpose of the front shaft seat is positioning. However, the transmission of parts such as crankshafts needs to be assembled from a single reference, and the limiting accuracy and the like play a great role, so that the internal structure and the installation mode of the front axle seat need to be designed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects of the prior art, the utility model provides a press front axle seat mounting structure, which comprises a machine body, a crankshaft, a front axle seat and an end cover, wherein the front axle seat is mounted on a mounting hole reserved on the machine body; the outer side of the end cover is sleeved with an oil seal, and the lower part of the front shaft seat is provided with an oil hole.
In order to ensure the flexibility of crankshaft rotation, a gap is reserved between the shaft shoulder of the crankshaft and the front shaft seat.
Furthermore, a reserved gap between the shaft shoulder of the crankshaft and the front shaft seat is 0.13-0.35 mm.
In order to better avoid the leakage of lubricating oil, the oil seal is a TC framework oil seal.
Furthermore, the screw is a socket head cap screw.
In order to facilitate the concentrated collection of the lubricating oil, furthermore, an annular oil guide groove is formed in the outer wall of the crankshaft front bearing and is located at the oil hole.
Furthermore, an oil return groove is formed in the lower portion of the front shaft seat.
Has the advantages that: in the utility model, (1) the crankshaft is limited by the end cover and the front axle seat, thereby improving the processing precision of the press;
(2) lubricating oil is utilized to keep lubrication between the end cover and the bearing, and meanwhile, the phenomenon that the lubricating oil leaks out is avoided through the oil seal;
(3) lubricating oil can be recovered in a centralized manner through the structure of the oil hole on the front axle seat;
(4) the clearance between the front axle seat and the shoulder of the crankshaft shaft can ensure the flexibility of the crankshaft.
