Description
Technical Field
The invention belongs to the technical field of oil pressure dampers for rail vehicles, and particularly relates to a single-circulation-structure damper core valve seat screwing assembly for a rail vehicle.
Background
The oil pressure vibration absorber for the rail vehicle is used for reducing vehicle suspension vibration, ensuring that the rail vehicle safely and stably runs on a line, and improving the riding comfort of passengers. The oil pressure vibration absorber can be divided into a single-circulation oil pressure vibration absorber and a double-circulation oil pressure vibration absorber according to the flow direction of oil liquid when the vibration absorber moves, the vibration absorber with the consistent flow direction of the oil liquid when the vibration absorber moves in a stretching mode and a compressing mode is called as a single-circulation vibration absorber, and the vibration absorber with the inconsistent flow direction of the oil liquid when the vibration absorber moves in the stretching mode and the compressing mode is called as a. Certain single-cycle shock absorbers cannot be directly operated by hands due to the fact that the threaded hole of the core valve seat is deep, and a common screwing device cannot fix the position of the core valve seat, so that operation is inconvenient.
Disclosure of Invention
In view of the above-mentioned shortcomings of the prior art, the present invention provides a single-cycle structure damper core-valve seat tightening assembly for a railway vehicle, wherein a magnet is installed in a tightening sleeve so as to be capable of attracting a core valve seat and fixing the position of the core valve seat for tightening.
In order to solve at least one of the above technical problems, the technical solution adopted by the present invention is:
a single cycle structure damper core valve seat tightening assembly for a rail vehicle, comprising: a torque wrench and a tightening socket, wherein,
the one end of screwing up the sleeve is equipped with the spread groove for with the torque spanner links to each other, it is equipped with the mounting groove to screw up the telescopic other end, is used for the embedding on the core disk seat, and be close to the mounting groove be equipped with magnet in screwing up telescopic main part, be used for the reinforcing it is telescopic fixity to screw up.
Further, the assembly further comprises: the bolt is close to be equipped with on the telescopic main part of screwing up of mounting groove and hold the chamber, magnet set up in hold the intracavity and pass through bolt locking is fixed.
Further, the connecting grooves are regular hexagons.
Further, the mounting groove is square.
The beneficial effects of the invention at least comprise: the magnet is arranged in the screwing sleeve, so that the magnet can adsorb the core valve seat to fix the position of the core valve seat so as to facilitate screwing, and the core valve seat can be screwed into the threaded hole of the core valve seat of the oil pressure shock absorber more conveniently and quickly.

Detailed Description
In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to specific examples. The following examples are illustrative only and are not to be construed as limiting the invention. The examples, where specific techniques or conditions are not indicated, are to be construed according to the techniques or conditions described in the literature in the art or according to the product specifications.
Referring to fig. 1-5, the single-cycle structure damper core valve seat screwing assembly for the rail vehicle mainly comprises a screwing sleeve 1, a bolt 2 and a magnet 3, wherein the magnet 3 is placed in a corresponding accommodating cavity of the screwing sleeve 1 and is screwed and fixed by the bolt 2, and the upper end and the lower end of the screwing sleeve 1 are respectively designed into a structure matched with a torque wrench and a core valve seat in a connecting mode.
More specifically: screw up telescopic one end and be equipped with the spread groove, be used for with the protruding cooperation of torque spanner, screw up telescopic other end and be equipped with the mounting groove, be used for the embedding on the core disk seat, and be close to the mounting groove be equipped with in the telescopic main part of screwing up and hold the chamber, magnet set up in hold the intracavity and pass through bolt locking is fixed, is used for the reinforcing screw up telescopic absorption fixity.
Preferably, the connecting groove is regular hexagon and is matched with a torque wrench. It will be appreciated that the torque wrench of the present invention is conventional in the art.
Preferably, the mounting groove is square, so as to be convenient for matching with the core valve seat.
The working principle of the screwing assembly is as follows: in the debugging process of shock absorber, need to change the core disk seat sometimes, and the core disk seat is submerged by hydraulic oil, needs fix the core disk seat with the tightening sleeve and screws in, and reuse moment spanner screws up.
In conclusion, the magnet is arranged in the screwing sleeve, so that the magnet can adsorb the core valve seat to fix the position of the core valve seat so as to facilitate screwing, and the core valve seat can be screwed into the core valve seat threaded hole of the oil pressure shock absorber more conveniently and quickly.
Although embodiments of the present invention have been shown and described, it is understood that the embodiments are illustrative and not restrictive, that various changes, modifications, substitutions and alterations may be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
