For Yuan, visual concrete condition understands above-mentioned term concrete meaning in this utility model.
As shown in Figure 1-Figure 3, this utility model embodiment provides a kind of lathe buffer limit mechanism, including overcoat 1 with
And buffering mandrel 2, it is sequentially provided with the first through hole the 101, second through hole 102 and third through-hole 103 in overcoat 1 on axis direction, the
One through hole the 101, second through hole 102 is connected with third through-hole 103, and the diameter of the first through hole 101 and third through-hole 103 is the biggest
Diameter in the second through hole 102.Buffering mandrel 2 includes guide post 201 and is located at thread segment 202 He at guide post 201 two ends
Locating part 203.Guide post 201 matches with the second through hole 102, it is preferable that guide post 201 and the second through hole in the present embodiment
102 matched in clearance, the second through hole 102 can be that guide effect is played in the motion of guide post 201 so that buffering mandrel 2 will not go out
Now bias.Locating part 203 matches with the first through hole 101, and locating part 203 and the first through hole 101 slipper seal；First through hole
101 and second through hole 102 formed step surface and locating part 203 between be provided with spring 3, spring 3 is sheathed on guide post 201
Outside；Thread segment 202 is provided with locking nut 5；Overcoat 1 is provided with one end of third through-hole 103 and is provided with sealing-plug 4.Specifically,
Buffering mandrel 2, overcoat 1 and sealing-plug 4 in the present embodiment all uses 301 rustless steels to make, and is possible to prevent corrosion and the oil of water
Corrosion, improves service life.
Cushion effect adjusting lock nut 5 the most as requested and the relative position buffering mandrel 2 thread segment 202 during use
Regulate the decrement of spring 3 namely regulate the buffer distance S shown in Fig. 1, specifically, it is provided that one will buffer mandrel 2 to the right
The pulling force drawn, makes the step surface between the right side of locking nut 5 and the second through hole 102 and third through-hole 103 fit, locking
Keep fixing under nut 5 frictional force between, rotate buffering mandrel 2 and regulate the position of thread segment 202 and locking nut 5
Put；Locating part 203 produces when swiftly passing object moves to the position of locating part 203 thrust, and buffering mandrel 2 is in thrust
Moving towards the one end being provided with sealing-plug 4 under effect, the spring 3 compressed absorbs the impulsive force of high-speed moving object, plays
Cushioning effect, when the cushion effect required is big, screws spring 3, and buffer distance S value reduces, it is desirable to when cushion effect is big, unscrew bullet
Spring 3, buffer distance S value increases.And owing to the position of overcoat 1 is fixing, locating part 203 is compressed under the effect of thrust
Concordant with the low order end end face of overcoat 1 to right side, it is achieved that high-speed moving object spacing.
Lathe buffer limit mechanism locating part 203 that this utility model provides and the first through hole 101 slipper seal, and the 3rd
Be provided with sealing-plug 4 at through hole 103, it is achieved that the sealing of lathe buffer limit mechanism so that its can apply to water, oil or other
In liquid, do not affect normal cushioning effect.Owing to high-speed moving object is existed buffering, improve limit accuracy, realizing
The regulation of buffer distance can be realized exactly by adjusting locking nut 5, for different objects while buffer limit
Spacing can provide different cushion effect, owing to the compression distance of spring 3 is smaller, cushion effect and compression distance are substantially linearly
Relation, can be easy to estimate cushion effect.And simple in construction, cost of manufacture are low, the probability that breaks down is little.
Further, in the present embodiment, locating part 203 is provided with the first sealed groove 204, sets in the first sealed groove 204
There is combined seal ring 6.Use combined seal ring 6 can provide sealing intensity and service life.
