Referring to fig. 2 to 4, the present invention provides a pipe coupling structure for an electromagnetic oil feeder of a dry oil lubrication system, which is used for connecting an electromagnetic oil feeder 1 and a pipe 2 in the dry oil lubrication system, wherein an interface of the electromagnetic oil feeder 1 is provided with an internal thread, the pipe coupling structure comprises a base 3 connected with the pipe 2, a connecting member 4 provided with an external thread and used for connecting the base 3 with the electromagnetic oil feeder 1, the base 3 is provided with a hollow mounting hole 31, the connecting member 4 passes through the hollow mounting hole 31 to be connected with the interface of the electromagnetic oil feeder 1 through the thread, the base 3 is provided with a connecting hole 32 perpendicular to the hollow mounting hole 31 and used for connecting the pipe 2 outside a side wall of the hollow mounting hole 31, a first hollow oil through hole 33 is provided between the connecting hole 32 and the hollow mounting hole 31, the connecting piece 4 is provided with an oil through blind hole 41 communicated with the interface of the electromagnetic oil feeder 1 in the axial direction, and the outer side of the side wall of the oil through blind hole 41 is provided with at least one second hollow oil through hole 43 communicated with the oil through blind hole 41. And sealing pieces 5 are arranged at the joint part of the connecting piece 4 and the base 3 and the joint part of the base 3 and the electromagnetic oil feeder 1.
The invention provides a working principle of a pipeline connecting structure of an electromagnetic oil feeder for a dry oil lubricating system, which is characterized in that when the pipeline 2 needs to be connected to the electromagnetic oil feeder 1, the pipeline 2 is firstly inserted into the connecting hole 32 of the base 3, and the pipeline 2 is connected with the base 3 (welded or screwed); the pipe 2 may be externally threaded, and the connection hole 32 may be internally threaded, so that the pipe 2 and the base 3 may be connected by screwing.
After the pipeline 2 is connected with the base 3, the connecting piece 4 is connected with the interface of the electromagnetic oil feeder 1 through the hollow mounting hole 31 by a screw thread, so that the pipeline 2 and the electromagnetic oil feeder 1 can be fixedly connected.
After the pipeline connecting structure of the electromagnetic oil feeder for the dry oil lubricating system is connected, grease flows out of the pipeline 2, flows into the gap between the connecting piece 4 and the hollow mounting hole 31 through the first hollow oil through hole 33, flows into the oil through blind hole 41 through the second hollow oil through hole 43, and the grease in the oil through blind hole 41 can freely enter the inlet of the electromagnetic oil feeder 1.
Because the pipeline 2 is fixedly connected with the base 3, when the electromagnetic oil feeder 1 needs to be connected, the pipeline 2 or the electromagnetic oil feeder 1 does not need to be subjected to any rotating sleeving operation, the position of the base 3 only needs to be adjusted to conveniently correspond to the interfaces of the electromagnetic oil feeders 1 at different positions, and then the assembly and disassembly are completed by using the connecting piece 4.
The connecting piece 4 can be a standard bolt, the oil through blind hole 41 and the second hollow oil through hole 43 can be formed by machining through a rotary machine, so that different types of standard bolts can be conveniently selected to process corresponding to different electromagnetic oil feeders, the production cost can be greatly reduced, and the production efficiency is improved.
The base 3 should have a high flatness, so that the sealing degree of the joint between the connecting member 4 and the base 3 and the joint between the base 3 and the electromagnetic oil feeder 1 can be ensured, and of course, a sealing member 5 can be additionally arranged at the joint to enhance the sealing property, thereby avoiding the risk of oil leakage during use.
In a preferred embodiment, the connecting member 4 is provided with a recessed portion 42 at the outer side of the side wall of the blind oil passing hole 41, and the second hollow oil passing hole 43 is provided in the recessed portion 42. When the pipeline connecting structure of the electromagnetic oil feeder for the dry oil lubricating system is in an operating state, the concave part 42 on the outer side of the side wall of the connecting piece 4 corresponds to the position of the first hollow oil through hole 33, so that the problem of unsmooth flow of grease caused by too small clearance between the connecting piece 4 and the hollow mounting hole 31 can be avoided, the grease flows out from the pipeline 2, firstly flows into the concave part 42 through the first hollow oil through hole 33, then smoothly flows into the oil through blind hole 41 through the concave part 42 and the second hollow oil through hole 43, and the grease in the oil through blind hole 41 can freely enter the inlet of the electromagnetic oil feeder 1.
The connecting piece 4 can be a standard bolt, and the concave part 42 can be formed by turning the surface of the standard bolt through a lathe, so that different types of standard bolts can be conveniently selected to process corresponding to different electromagnetic oil feeders, the production cost can be greatly reduced, and the production efficiency can be improved.
In a preferred embodiment, the width of the recess 42 is greater than the diameter of the first hollow oil passage hole 32. This reduces the assembly requirements for the connector 4, simplifies the production process and reduces the assembly costs.
In a preferred embodiment, the diameter of the first hollow oil through hole 32 is smaller than the inner diameter of the pipeline 2, so that the hidden trouble that the pipeline 2 is excessively hard to enter the hollow mounting hole 31 during the assembling process so as to influence the assembling of the connecting piece 4 is avoided.
In a preferred embodiment, the seal 5 is a gasket. Therefore, the sealing degree of the joint part of the connecting piece 4 and the base 3 and the joint part of the base 3 and the electromagnetic oil feeder 1 can be increased by selecting standard sealing gaskets on the market, and engineering cost can be saved.
In a preferred embodiment, two second hollow oil passing holes 43 symmetrical on the same central axis are arranged outside the side wall of the oil passing blind hole 41. Therefore, on one hand, the processing is convenient, for example, when the connecting piece selects a standard bolt, two second hollow oil through holes 43 can be processed only by one-time hole-rotating processing of the rotary machine; on the other hand, the two second hollow oil passing holes 43 may increase a flow passage space of grease so that the flow of oil is smoother.
The utility model provides a pipeline draw bail for grease lubricating system's electromagnetism oil feeder, it is arranged in connecting electromagnetism oil feeder and pipeline in grease lubricating system, because pipeline and base fixed connection, and need not direct with electromagnetism oil feeder entry linkage, consequently when needs connect during the electromagnetism oil feeder, just need not do any rotation to pipeline or electromagnetism oil feeder again and cup joint the operation, only need the position of adjustment base can conveniently correspond with the interface of the electromagnetism oil feeder of different positions, then utilize the connecting piece can easily accomplish assembly and dismantlement.
