A kind of bowl-type plug installation tool
Technical field
This utility model relates to installation tool technical field, particularly relates to a kind of bowl-type plug installation tool.
Background technology
During the bowl-type plug of cylinder body press-fits, need by bowl-type plug press-in cylinder body main oil gallery and to carry out riveting point at oil duct junction with special pressure head.It is that a concrete numerical value cannot regulate that existing bowl-type plug pressure head press-fits the degree of depth, cannot repair, can only change after pressure head abrasion;Pull down together with needing the depression bar that will coordinate with it when pressure head is changed, operation complexity.
In existing open file, to have notification number be CN203665030U, the day for announcing is the Chinese patent literature of 2014.06.25, discloses a kind of bowl-type patch installation tool, and it includes base plate, base plate arranges alignment pin, and described alignment pin is fastened by nut;Base plate lower end and sleeve connection, and fixed by the hexagon socket head cap screw at two ends;Waist hole is had on described sleeve;Strike axle and be installed on sleeve inner, and be fixed in waist hole by flush end holding screw.This technical scheme provides the benefit that, can realize striking axle axis substantially vertical with bowl-type patch, can effectively prevent bowl-type patch from striking partially;Lifting surface area when this technical scheme makes bowl-type patch strike dress increases, it is to avoid strike bad plane of constraint.This technical scheme is disadvantageous in that, the effective active length striking head is fixed, cannot be regulated, may be only available for certain set press-fit the degree of depth, when required press-fit the degree of depth change time, i.e. cannot be suitable for.
Utility model content
Complicated for solving existing structure, bowl-type plug press-fits the problem of degree of depth inconvenience regulation, and this utility model offer one is simple and reliable for structure, can regulate bowl-type plug press-fits the degree of depth, pressure head dismounting and change convenient bowl-type plug installation tool.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of bowl-type plug installation tool, including pressure head, also includes guide pin bushing, guide pin bushing has through hole, pressure head is slidably matched in through-holes, and the upper surface of pressure head connects regulation screw, and regulation screw is combined with locking nut.Screw in the degree of depth of pressure head by adjusting regulation screw, adjust pressure head and stretch out the length of guide pin bushing, thus play regulation bowl-type lid and press-fit the purpose of the degree of depth.
As preferably, the outer wall of guide pin bushing is provided with some marks closely screw, marks closely to be combined with in screw and marks closely screw, and the side of pressure head is provided with the pressure tank that bottom surface is plane, marks closely screw and is pressed together on the pressure tank bottom surface of pressure head.Mark closely screw for compressing pressure head, make ram position fix.
As preferably, the surface of through hole is provided with the guide groove being parallel to through-bore axis, and pressure head is provided with the guide block coordinated with guide groove.The cooperation of guide groove and guide block by being parallel to through-bore axis, makes pressure head slip in through-holes more smooth and easy, and pressure head does not haves situation about rotating in through-holes.
The beneficial effects of the utility model are: simple and reliable for structure, it is possible to regulation bowl-type plug press-fits the degree of depth, pressure head dismounting and change conveniently.

Fig. 1 is this utility model structural representation;
In figure: 1. pressure head, 11. pressure tanks, 12. guide blocks, 2. guide pin bushing, 21. through holes, 22. mark closely screw, 23. guide grooves, and 3. regulation screw, 4. locking nut, 5. marks closely screw, 6. press-loading device.
Detailed description of the invention
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of bowl-type plug installation tool, including pressure head 1, guide pin bushing 2, guide pin bushing 2 having through hole 21, pressure head 1 is slidably fitted in through hole 21, and the upper surface of pressure head 1 connects regulation screw 3, and regulation screw 3 is combined with locking nut 4;Locking nut 4 is locked on the upper surface of pressure head 1, the outer wall of guide pin bushing 2 is provided with some marks closely screw 22, mark closely screw 22 is combined with and mark closely screw 5, the side of pressure head 1 is provided with the pressure tank 11 that bottom surface is plane, mark closely screw 5 and be pressed together on pressure tank 11 bottom surface of pressure head 1, when needs adjust bowl-type lid compression distance, take out pressure head 1 and connect superincumbent regulation screw 3 and locking nut 4, then locking nut 4 is unscrewed, adjust regulation screw 3 and screw in the degree of depth of pressure head 1, the most again screw locking nut 4, load in through hole 21;When pressure head 1 weares and teares or other reasons needs mill to repair or changes, unscrew and mark closely screw 5, pressure head 1 is extracted out from through hole 21 and processes, the most again fill in through hole 21 and can be continuing with, the surface of through hole 21 is provided with the guide groove 23 being parallel to through hole 21 axis, and pressure head 1 is provided with the guide block 12 coordinated with guide groove 23.During use, with screw, this utility model is fixed on press-loading device 6, can be by press-loading device 6 band dynamic head 1 by the oil duct of bowl-type lid press-in oil cylinder.
