Abstract
The invention discloses a device for press fitting of a diesel engine valve seat. The device comprises a framework, and a T-shaped screw is arranged on the upper end face of the framework in a penetrating manner. The lower end of the screw is connected with an automatic leveling pressure head and a guiding pressure head, the guiding pressure head is a lengthened pressure head stretching into the valve seat, the automatic leveling pressure head comprises a spherical surface pressure head body and a sleeving part, and the spherical surface pressure head body is sleeved with the sleeving part. The sleeving part is cylindrical and internally provided with a groove with an upward groove opening. An inner threaded section is arranged at the upper portion of the sleeving part, and an outer threaded section is arranged at the lower portion of the spherical surface pressure head body. The device aims to ensure the guiding reliability of assembling of the valve seat, the reliability of press-fitting alignment of the valve seat and easy and convenient assembling; a handle is rotated to drive the screw to be downward, the automatic pressure head tightly presses the guiding pressure head so that the valve seat can be tightly pressed, the positioning guiding reliability can be ensured, and the valve seat can be assembled to be in place at a time; meanwhile, jamming caused by frequent use of the screw is avoided by the adoption of a copper thread sleeve; and the device is simple in structure and convenient to use.
Description
Technical field
The present invention relates to a kind of device for press-fiting diesel engine valve seat, belonging to field of mechanical technique.
Background technology
Valve seat plays a key effect in the installation process of valve, at present, the assembling of valve seat is complete with simple aid substantially, that knocks pressure head by copper rod defeats tight valve seat, because artificial percussion power is uneven, frock, without guiding, easily makes valve seat fill partially stuck, damage cylinder head inwall, easily causes valve seat and cylinder head to scrap.
Summary of the invention
Given this, the invention provides a kind of assembly reliability high, structure is simple, the device for press-fiting diesel engine valve seat easy to use.
Its technical scheme is as follows:
A kind of device for press-fiting diesel engine valve seat, comprise frame-type frame, the upper surface of this frame-type frame is equipped with "T"-shaped screw rod, the lower end of this screw rod is connected with Automatic Levelling pressure head and guiding pressure head, and this guiding pressure head is the lengthening pressure head stretching into valve seat inside, and Automatic Levelling pressure head comprises sphere pressure head and is socketed in the socket part outside this sphere pressure head, this socket part is cylindric, be provided with groove in it, above this groove, be provided with internal thread segment, below described sphere pressure head, be provided with external thread section.Design like this, by the guiding of valve seat assembling and press-fit centering reliability and assemble easy for the purpose of, drive screw rod downward by rotary handle, Automatic Levelling pressure head compresses guiding pressure head to realize compression valve seat, ensure that positioning and guiding is reliable, make that valve seat is disposable to be seated.
As preferably, the upper end of described screw rod is provided with handle.Design like this, conveniently carries out screw rod rotation.
As preferably, the part that described screw rod contacts with the upper surface of frame-type frame is arranged with copper swivel nut, and this copper swivel nut is connected with the upper surface of described frame-type frame by the bolt being arranged on its circumference one circle.The copper swivel nut installed avoids screw rod and occurs jam phenomenon because often using.
Beneficial effect:
The device for press-fiting diesel engine valve seat of above technical scheme, by rotating screw bolt, Automatic Levelling pressure head is compressed with guiding pressure head, ensure that positioning and guiding is reliable, make that valve seat is disposable to be seated, adopt copper swivel nut to avoid screw rod simultaneously and occur jam phenomenon because often using, alleviate the degree of difficulty of valve seat assembling, improve the reliability of assembling, and structure is simple, easy to use.
