Specific embodiment
Further describe technical scheme below in conjunction with the accompanying drawings, but claimed scope is not limited to institute
State.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of hydraulic cylinder end face drilling tool of the present invention, pacifies relatively including opening
Hold cover plate 1 and upper cover plate 6, be provided with swivel nut 2, interior positioning sleeve 8 and die sleeve 5, institute between described upper cover plate 6 and lower cover 1
State swivel nut 2 openend to be threaded connection with upper cover plate 6, bottom surface is machined with centre bore；Described interior positioning sleeve 8 lower end is nested in spiral shell
In the bottom centre hole of set 2；Interior positioning sleeve 8 and swivel nut 2 bottom are connected with lower cover 1 respectively, and interior positioning sleeve 8 and lower cover 1 are equal
It is machined with centre bore；Described die sleeve 5 inwall be cone structure, tip upside down between upper cover plate 6 and interior positioning sleeve 8, die sleeve 5 end face with
Swivel nut 2 bottom surface is machined with one-to-one spring mounting groove respectively, and at least 4 groups of mounting groove, at swivel nut 2 bottom surface and die sleeve 5 end
On face, circumference is uniformly distributed, and is provided with return spring 3 in mounting groove.
Described die sleeve 5 bottom surface is provided with ring-shaped step 51, and described ring-shaped step 51 inwall is joined with interior positioning sleeve 8 upper end outer wall
Close；There are some nibs 52, the quantity of nib 52 and diameter in die sleeve 5 bottom all in accordance with to be processed close to central hole is circumferentially distributed
The hole number of the required processing of cylinder sleeve 10 end face and diameter to determine, different model is devised according to the hole of varying number and diameter
Die sleeve 5, during use only need on demand select change；It is provided with drill bushing 9, drill bushing 9 is according to different moulds in described nib 52
The hole 52 aperture and different model of aperture design in hole need to be processed for selecting.
On the jacket wall of described interior positioning sleeve 8, circumference is evenly distributed with least 4 radial direction through hole, is respectively equipped with radially in through hole
The bulb push rod 7 installed, the bulb end of described bulb push rod 7 and die sleeve 5 contact internal walls, the other end be arranged at interior positioning sleeve 8
Interior curved splint 11 connects；Bar between the bulb and interior positioning sleeve 8 of described bulb push rod 7 is provided with push rod spring 71.
Described upper cover plate 6 outer wall is provided with circumferentially distributed rotary handle 4, in order to rotary upper cover plate 6；Described swivel nut 2
Gap is left, so that die sleeve 5 moves freely in swivel nut 2 along the vertical direction between inwall and die sleeve 5 outer wall.
Die sleeve 5 adopts mould steel to process, and hardness reaches 58-62hrc, and wearability is preferable；Adopt in lathe in machining simultaneously
The conical surface and cylindrical each spot size, the size after processing and positional precision are high；Each hole position on die sleeve 5 is added using machining center
Work, position degree can control within 0.05mm.
Spherical push rod 7 adopts mould steel to process, and dimension control, within 0.05mm, matches after after processing, packet selects
Use；The bottom centre hole of lower cover 1 and interior positioning sleeve 8 is slightly larger in dimension than the maximum material size of cylinder sleeve 10, so that part energy
Smoothly put into.
Employed in the technical program, spring is standard component, and after assembling with each part, quality of fit is high, and part centering is accurate
Exactness is high.
During work, after each part is completed, cylinder sleeve 10 is passed through lower cover 1 centre bore and interior from lower cover 1 bottom
Positioning sleeve 8 inserts frock, and die sleeve 5 now, in the presence of return spring 3, is in the top position, bulb push rod 7 is in push rod
It is in die sleeve 5 inner conical surface opening maximum end position, cylinder sleeve 10 is successfully inserted between curved splint 11 in the presence of spring 71；Logical
Cross rotary handle 4 rotation upper cover plate 6, upper cover plate 6 moves down with screw thread rotation, promote die sleeve 5 to move down, die sleeve 5 interior
The conical surface and the bulb end in contact of bulb push rod 7, radial component is overcome the spring force of push rod spring 71, is acted on by bulb push rod 7
On curved splint 11, cylinder sleeve 10 is clamped by curved splint 11；Now, create between curved splint 11 and cylinder sleeve 10 active force with
Reaction force, the reaction force of cylinder sleeve 10 is delivered on bulb push rod 7, the little place in gap, and active force is larger, makes bulb push rod
7 promote drill bushing 5 to produce a displacement, the opposing party's gap shrinks, and bulb push rod promotes drill bushing 5 to produce a position in the direction again
Move, and so on, after the active force of all directions reaches balance, the center of die sleeve 5 and part 10 is i.e. by centering, above procedure
Moment can complete, and now the center of the nib 52 on die sleeve 5 is the center in hole to be processed；Now it is only necessary in mould
Load onto the drill bushing 9 of corresponding model in hole 52, in drill bushing 9, cylinder sleeve 10 end face is holed one by one by drilling machine it is possible to complete to bore
Hole operation.
