Field.
Background technology
At present, the oil cylinder parts important as engineering machinery, its performance directly affects the competitiveness of main frame.And piston
As the important spare part of oil cylinder, the hydraulic oil for completely cutting off its both sides is not only needed, it is also necessary to moved back and forth in cylinder barrel；In order to anti-
Run-off the straight when only piston moves back and forth in cylinder barrel, supporting construction is typically equipped with piston.The supporting construction of piston at present
Predominantly guide ring, i.e., the Q-RING of cloth material or Copper alloy material is pressed from both sides using phenolic aldehyde, is placed in the groove of outer surface of piston,
Support reciprocating motion of the pistons.This supporting way coefficient of friction is higher, and when high speed moves back and forth, guide ring is easily ground
Damage, heating, until damage；Meanwhile this whole circle lock ring is slidably matched, to inner hole of cylinder, piston channel, guide ring in itself
Requirement on machining accuracy is very strict, once occurring deviation in precision, then coordinates and the phenomenon of tension easily occurs, trigger oil cylinder to climb
Row, shake etc. are abnormal, reduce reliability and life-span that oil cylinder uses.
In view of this, China Patent No. 201420438106.5, it is entitled《A kind of oil cylinder》Disclosing effectively to keep away
Exempt from the technology of drawbacks described above, the main points of the technology are to set an annular groove at the both ends of piston, in described groove
Steel ball is set, the purpose of guiding is realized using the rolling movement of steel ball and inboard wall of cylinder block, it is clear that groove can be subject to processing precision
Influence, meanwhile, steel ball and groove are having a certain degree of abrasion after working after a while, it is clear that this can not
Ensure the correct guidance of piston, the purpose of the present invention is exactly the drawbacks described above present in prior art, is proposed a kind of new
Oil cylinder piston guiding mechanism.
The content of the invention
It is an object of the invention to：For the above mentioned problem present in existing oil cylinder piston guiding mechanism, the present invention provides
A kind of new oil cylinder piston guiding mechanism.
Technical scheme is used by the present invention realizes above-mentioned purpose：A kind of oil cylinder piston guiding mechanism, it include cylinder body,
Piston rod, the end that described piston rod is in cylinder body have piston locating journal part and male thread portion, its feature
It is：Main piston is installed in piston locating journal part, in the both sides of main piston peace one auxiliary piston of each installation, described main piston
Both sides respectively make a circular conical surface close to cylindrical position, the described auxiliary piston side relative with main piston is formed with and main piston
Upper identical circular conical surface, each socket one on the piston locating journal part between the main piston corresponding thereto auxiliary piston of side
Adjusting pad, set in the V-shape opening groove that is formed of two circular conical surfaces of the main piston auxiliary piston of side corresponding thereto some
Steel ball, one nut is set in threaded portion part, the nut fixes two auxiliary pistons and main piston and two adjusting pads
On the piston locating journal part of piston rod, cylinder body is socketed in two auxiliary pistons and master on piston rod with its endoporus
Piston it is cylindrical on, pass through adjust two adjusting pads thickness, it is possible to adjust the exposure level between steel ball and inboard wall of cylinder block,
In order to reach preferable sealing effectiveness, in the cylindrical between inboard wall of cylinder block and two auxiliary pistons and piston rod of two auxiliary pistons
Between sealed respectively with auxiliary piston exterior seal ring and auxiliary piston inner seal ring, equally, the inwall of main piston and cylinder body it
Between and main piston and piston rod between sealed respectively with main piston exterior seal ring and main piston inner seal ring.
Beneficial effect：The present invention is due to the thickness by adjusting two adjusting pads, it is possible to adjusts steel ball and inboard wall of cylinder block
Between exposure level, own, the present invention have manufacturing process it is simple, it is convenient to install and maintain the advantages of, enable in particular to ensure live
Good guiding can be kept between plug and cylinder body, so as to not only improve the service life of piston rod, reduce the cost used.
