Description
Technical field
The present invention relates to hydraulic cylinder processing technique field more particularly to a kind of oil cylinder elongated hole oil ducts for reducing scrappage
Processing method.
Background technique
Oil cylinder inner cylinder in hydraulic system, mainly by check ring mounting groove, upper copper sheathing mounting surface, outer oil passage outlet, oil
Road, internal oil channel outlet and lower copper sheathing mounting surface etc. are constituted.When carrying out the processing of oil cylinder, need to process internal oil channel, this
It is related to the processing to elongated hole.
However in the prior art, in order not to damaging upper copper sheathing mounting surface when processing internal oil channel, it is often necessary to oil duct into
The eccentric design of row, can so cause easily to puncture oil duct outer surface when being processed with depth drill.It is main meanwhile when processing internal oil channel
It takes and improves process equipment precision, reduce the amount of feeding in boring procedure, to control processing aperture size precision and processing
The mode of hole degree of skewness reduces product rejection rate.However though elongated hole side wall can be avoided reluctantly not breakdown in this way, to part
Processing more stringent requirements are proposed, be because equipment purchase funds improve, processing efficiency slows down causes processing cost thereupon
Increase.
Therefore, it is necessary to provide a kind of completely new oil cylinder elongated hole oil duct processing method, the scrappage of oil duct processing is reduced,
Increase the efficiency of oil duct processing simultaneously.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of oil cylinder elongated hole oil duct processing method for reducing scrappage.
A kind of oil cylinder elongated hole oil duct processing method reducing scrappage provided by the invention., adopt the following technical scheme that
A kind of oil cylinder elongated hole oil duct processing method reducing scrappage, comprises the following steps that
(1) the outer circle center of correction main body blank first, with centre drill feather plucking base both ends end-face central hole, by both ends end-face central hole
It gets through, forms oil duct 1, the present invention directly carries out centering design to oil duct 1, and both sides surplus is larger, tentatively reduces depth drill and adds
Scrappage in work.
(2) blank upper end end face is drilled in using deep hole process elongated internal oil channel hole 2 vertically downward.
(3) hole 3 laterally outside are processed on the outside of blank using drilling machine, inside transverse holes 4 are processed on the inside of blank,
Make laterally outside that hole 3, inside transverse holes 4 are connected to internal oil channel hole 2.
(4) blank upper end end face to the elongated hole between hole 3 laterally outside is crammed.
(5) lower copper sheathing mounting surface 5, lower check ring mounting groove 51 are processed on the oil duct 1 of lower part in blank；In blank
Upper copper sheathing mounting surface 6, upper spring back-up ring mounting groove 61 are processed on the oil duct 1 on outer top.
Preferably, in blank both ends end face processing oil duct 1, there are the surpluses of 3-4mm on the outside of oil duct 1 and blank.
Further, in blank both ends end face processing oil duct 1, there are the surpluses of 4mm on the outside of oil duct 1 and blank.
In step (4), blank upper end end face to the elongated hole between hole 3 laterally outside is carried out using filler welding
It crams.
Preferably, the filler welding is to cram elongated hole using laser welded material, then uses laser irradiation
It is crammed.
Compared with the relevant technologies, the present invention is had the following technical effect that
(a) a kind of new concept of Small and Deep Hole Machining is introduced --- shape, position constraint point are first machined out, then carried out thin
Long hole machined, finally to being finished after shape, position constraint point repair welding；
(b) it avoids when carrying out Small and Deep Hole Machining with depth drill, causes side wall punch-through because unilateral surplus is less；
(c) processing of oil cylinder elongated hole oil duct is carried out by the invention, scrappage is fallen sharply by 70% to 5%, greatly reduces production
Product scrappage, improves economic benefit.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of oil cylinder inner cylinder of the present invention.
Specific embodiment
Below in conjunction with drawings and embodiments, the invention will be further described.
As shown in Figure 1, a kind of oil cylinder elongated hole oil duct processing method of reduction scrappage of the invention, including following step
It is rapid:
(1) the outer circle center of correction main body blank first, with centre drill feather plucking base both ends end-face central hole, by both ends end-face central hole
It gets through, forms oil duct 1, the present invention directly carries out centering design to oil duct 1, and both sides surplus is larger, tentatively reduces depth drill and adds
Scrappage in work.
(2) blank upper end end face is drilled in using deep hole process elongated internal oil channel hole 2 vertically downward.
(3) hole 3 laterally outside are processed on the outside of blank using drilling machine, inside transverse holes 4 are processed on the inside of blank,
Make laterally outside that hole 3, inside transverse holes 4 are connected to internal oil channel hole 2.
(4) blank upper end end face to the elongated hole between hole 3 laterally outside is crammed.
(5) lower copper sheathing mounting surface 5, lower check ring mounting groove 51 are processed on the oil duct 1 of lower part in blank；In blank
Upper copper sheathing mounting surface 6, upper spring back-up ring mounting groove 61 are processed on the oil duct 1 on outer top.
Embodiment 1
In the present embodiment, a kind of oil cylinder elongated hole oil duct processing method reducing scrappage, comprises the following steps that
