Abstract
The utility model discloses a diesel engine disk seat pressure equipment pressure head, including auto seeking plane pressure head and extension direction pressure head, the auto seeking plane pressure head includes sphere pressure head and the portion of cup jointing outside this sphere pressure head of cup jointing, should the portion of cup jointing is cylindric, is provided with the recess in it, and the top of this recess is provided with the internal thread, the hypomere of sphere pressure head is provided with the external screw thread section, extension direction pressure head is the cylinder of elongated echelonment, and its top diameter is greater than the below diameter. Structure more than adopting, during the use, the direction that will extend pressure head leads in stretching into the disk seat, and the auto seeking plane pressure head carries out placing behind the alignment up end at extension direction pressure head, then compresses tightly the installation to the disk seat, has improved the reliability of assembly greatly.
Description
Technical field
This utility model relates to a kind of diesel engine valve seat crimping pressure head, belongs 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 completes with simple aid substantially, tight valve seat is defeated by what copper rod knocked pressure head, owing to artificial percussion power is uneven, instrument used does not lead and position limiting structure, it is easy to make valve seat dress partially stuck, damage cylinder head inwall, it is easy to cause valve seat and cylinder head to scrap。
Utility model content
In consideration of it, this utility model provides a kind of diesel engine valve seat crimping pressure head that can improve assembly reliability。
Its technical scheme is as follows:
A kind of diesel engine valve seat crimping pressure head, including Automatic Levelling pressure head and lengthening guiding pressure head, described Automatic Levelling pressure head includes sphere pressure head and the socket part being socketed in outside this sphere pressure head, this socket part is cylindrical, groove it is provided with in it, this groove be provided above female thread, the hypomere of described sphere pressure head is provided with external thread section；
The described guiding pressure head that lengthens is the stair-stepping cylinder lengthened, and its top diameter is more than diameter below。
Adopting above structure, during use, the pressure head that lengthening led stretches in valve seat and leads, and Automatic Levelling pressure head is placed on the upper surface lengthening guiding pressure head after carrying out centering, then carries out valve seat compressing and installs, substantially increases the reliability of assembling。
As preferably, the external diameter of described sphere pressure head is less than the internal diameter of socket part。It is so designed that, it is simple to sphere pressure head is arranged on inside socket part and carries out automatic capturing。
As preferably, described Automatic Levelling pressure head and lengthening guiding pressure head material are steel。
Beneficial effect:
The diesel engine valve seat crimping pressure head 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 simple in construction, easy to use。
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
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 utility model is described in further detail。
A kind of diesel engine valve seat crimping pressure head as depicted in figs. 1 and 2, including Automatic Levelling pressure head 1 and lengthening guiding pressure head 2, described Automatic Levelling pressure head 1 includes sphere pressure head 11 and the socket part 12 being socketed in outside this sphere pressure head 11, this socket part 12 is cylindrical, groove 121 it is provided with in it, this groove 121 opening upwards, the epimere in groove 121 is provided with female thread 1211, the hypomere of described sphere pressure head 11 is provided with external thread section 111, and the external diameter of described sphere pressure head 11 is less than the internal diameter of socket part 12。
The described guiding pressure head 2 that lengthens is the stair-stepping cylinder lengthened, and its top diameter is more than diameter below。Described Automatic Levelling pressure head 1 and lengthening guiding pressure head 2 material are steel。
During use, the pressure head 2 that lengthening led stretches in valve seat and leads, and Automatic Levelling pressure head 1 is placed on the upper surface lengthening guiding pressure head 1 after carrying out centering, then carries out valve seat compressing and installs, substantially increases the reliability of assembling。
