Abstract
The invention discloses a pressing head for press-mounting of a diesel engine valve seat. The pressing head for press-mounting of the diesel engine valve seat comprises an automatic leveling pressing head body and a lengthened guide pressing head body. The automatic leveling pressing head body comprises a spherical pressing head part and a sleeving part, wherein the spherical pressing head part is sleeved with the sleeving part; the sleeving part is cylindrical, a groove is formed in the sleeving part, and an internal thread section is arranged on the upper section of the groove; an external thread section is arranged on the lower section of the spherical pressing head part. The lengthened guide pressing head body is a lengthened step-shaped cylindrical pressing head body, and the diameter of the upper portion of the lengthened guide pressing head body is larger than that of the lower portion of the lengthened guide pressing head body. By the adoption of the structure, when the pressing head is in use, the lengthened guide pressing head body is stretched into the valve seat for guiding, the automatic leveling pressing head body is placed on the upper end face of the lengthened guide pressing head body after achieving leveling, then the valve seat is press-mounted, and the assembly reliability is greatly improved.
Description
Technical field
The present invention relates to a kind of pressure head 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, instrument used does not lead and position limiting structure, 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 pressure head for press-fiting diesel engine valve seat that can improve assembly reliability.
Its technical scheme is as follows:
A kind of pressure head for press-fiting diesel engine valve seat, comprise Automatic Levelling pressure head and lengthen guiding pressure head, described 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, groove is provided with in it, the epimere of this groove is provided with internal thread segment, is provided with external thread section below described sphere pressure head;
Described lengthening guiding pressure head is the stair-stepping the column indenter indentation lengthened, and above it, diameter is greater than below diameter.
Adopt above structure, during use, stretched in valve seat by lengthening guiding pressure head and lead, Automatic Levelling pressure head is placed on the upper surface lengthening guiding pressure head after carrying out centering, then carry out compression to valve seat and install, substantially increase the reliability of assembling.
As preferably, the external diameter of described sphere pressure head is less than the internal diameter of socket part.Design like this, is convenient to that sphere pressure head is arranged on inside, socket part and carries out automatic capturing.
As preferably, described Automatic Levelling pressure head and the material lengthening guiding pressure head are steel.
Beneficial effect:
The pressure head for press-fiting diesel engine valve seat of above technical scheme, Automatic Levelling pressure head carries out centering, lengthen guiding pressure head to lead, coordinated by Automatic Levelling pressure head and lengthening guiding pressure head, ensure that positioning and guiding is reliable, make that valve seat is disposable to be seated, improve reliability and the efficiency of assembling, and structure is simple, easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the sectional view of the Automatic Levelling pressure head in Fig. 1.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the invention will be further described.
A kind of pressure head for press-fiting diesel engine valve seat as depicted in figs. 1 and 2, comprise Automatic Levelling pressure head 1 and lengthen guiding pressure head 2, the socket part 12 that described Automatic Levelling pressure head 1 comprises sphere pressure head 11 and is socketed in outside this sphere pressure head 11, this socket part 12 is in cylindric, groove 121 is provided with in it, this groove 121 opening upwards, epimere in groove 121 is provided with internal thread segment 121, be provided with external thread section 111 below described sphere pressure head 11, the external diameter of described sphere pressure head 11 is less than the internal diameter of socket part 12.
Described lengthening guiding pressure head 2 is the stair-stepping the column indenter indentation lengthened, and above it, diameter is greater than below diameter.Described Automatic Levelling pressure head 1 and lengthening guiding pressure head 2 material are steel.
During use, lengthening guiding pressure head 2 is stretched in valve seat and leads, be placed on the upper surface lengthening guiding pressure head 1 after Automatic Levelling pressure head 1 carries out centering, then compression carried out to valve seat and install, substantially increase the reliability of assembling.
