Abstract
An assistant pressing tool comprises a base for placing a cylinder head seat ring and a guide sleeve arranged in a central hole of the base and on an elastic body, wherein a guide mandrel for placing a cylinder head conduit is arranged in an inner hole of the guide sleeve; a pressure head is arranged at the upper end of the guide mandrel; and the pressure head drives the guide mandrel and the guide sleeve to move downward at the same time, so that the cylinder head conduit and the cylinder head seat ring can be pressed in a cylinder head. The cylinder head conduit and the cylinder head seat ring can be pressed in place at the same time, the coaxiality of the cylinder head conduit and the cylinder head seat ring is ensured, and the quality of product is improved.
Description
Technical field
The utility model relates to a kind of accessory that press-fits, and is specifically related to a kind of cylinder head conduit, the cylinder head seat ring press-fits accessory.
Background technology
Adopt the pin-and-hole location when press-fiting cylinder head conduit and cylinder head seat ring at present; In press-fiting process, not only cause the locating hole distortion easily; And owing to itself position difference is just arranged between cylinder head guide hole and the locating hole, so the axiality that press-fits back cylinder head conduit and cylinder head seat ring is poor.
The utility model content
The purpose of the utility model is to provide a kind of accessory that press-fits that can guarantee cylinder head conduit and cylinder head seat ring axiality.
The purpose of the utility model is to realize like this; A kind ofly press-fit accessory; It is characterized in that: comprise the base of placing the cylinder head seat ring and the fairlead that is arranged in the centre hole of base, on the elastomer; Said fairlead endoporus is provided with the guiding mandrel of placing the cylinder head conduit, and said guiding mandrel upper end is provided with pressure head, thereby pressure head drives the guiding mandrel downwards and fairlead moves downward simultaneously and can cylinder head conduit and cylinder head seat ring be press fit in the cylinder head.
Above-mentioned elastomer is a spring.
Above-mentioned base is arranged on the workpiece limiting plate, is provided with screw plug between said centre hole of base and the workpiece limiting plate.
When press-fiting, earlier the cylinder head seat ring is put on the base, the cylinder head with completion of processing is through on the fairlead then; The cylinder head conduit is through on the guiding mandrel; The mandrel that will lead inserts in the fairlead endoporus, and when forcing press promoted pressure head, pressure head drive guiding mandrel moved downward the spring below the fairlead compression; The cylinder head conduit that is through on the guiding mandrel is press fit in the cylinder head; The cylinder head seat ring that will be placed on simultaneously on the base also is press fit in the cylinder head, and when the cylinder head conduit touched confined planes, cylinder head conduit and cylinder head seat ring were press-fit into place simultaneously.
The utlity model has following beneficial effect, the utility model can with the cylinder head conduit and the cylinder head seat ring is disposable be press-fit into place simultaneously, has guaranteed the alignment of cylinder head conduit and cylinder head seat ring, has improved product quality.
Description of drawings
Fig. 1 is pressed into the pre-structure sketch map for the utility model embodiment cylinder head conduit and cylinder head seat ring;
Fig. 2 is that the utility model embodiment cylinder head conduit and cylinder head seat ring are pressed into the back structural representation.
The specific embodiment
Embodiment; A kind ofly press-fit accessory, comprise base 3 and be arranged on the workpiece limiting plate 1, be provided with fairlead 5 in base 3 centre bores; Said fairlead 5 endoporus are provided with the guiding mandrel 7 of placing cylinder head conduit 8; Said guiding mandrel 7 upper ends are provided with pressure head 10, are provided with spring 4 below the last fairlead 5, are provided with screw plug 2 between base 3 centre bores and the workpiece limiting plate 1.
When press-fiting, earlier cylinder head seat ring 6 is put on the base 3, the cylinder head 12 with completion of processing is through on the fairlead 5 then, cylinder head conduit 8 is through on the guiding mandrel 7 again, and the mandrel 7 that will lead inserts in fairlead 5 endoporus; When forcing press promotes pressure head 10; Pressure head 10 drives guiding mandrel 7 moves downward the following spring 4 of fairlead 5 compressings; The cylinder head conduit 8 that is through on the guiding mandrel 7 is press fit into 12 li of cylinder heads; The cylinder head seat ring 6 that will be placed on simultaneously on the base 3 also is press fit into 12 li of cylinder heads, and when cylinder head conduit 8 touched cylinder head confined planes 11, cylinder head conduit 8 was press-fit into place with cylinder head seat ring 6 simultaneously.
