Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples:
As shown in Figures 1 to 5, the long boom end fixed structure of a kind of surgical operation auxiliary robot instrument, including instrument seat 1
With stock 2, stock 2 is in interference fit in casing 8.
The top of instrument seat 1 can be fixed with by wheel seat 4, as shown in fig. 6, instrument seat 1 accommodates the lower part of the cavity 1a of stock 2
It is provided with bearing block 1b, top is provided with bearing cap 3, and the upper surface of bearing cap 3 is against the lower end surface for leaning on wheel seat.Bearing cap 3 with
First bearing 5, bearing insert 6 and second bearing 7 are disposed between bearing block 1b.
Casing 8 is in interference fit in first bearing 5 and second bearing 7.
Casing 8, which has, prevents casing 8 and bearing from generating the step structure being axially moved.Specifically, the step structure of casing 8
Including top bar 81 and get out of a predicament or an embarrassing situation 82, top bar 81 has the terrace 81a that appears on the stage against 5 upper surface of first bearing;Get out of a predicament or an embarrassing situation 82
With the leave from office terrace 82a against most 7 lower end surface of second bearing.
The middle part of casing 8 is provided with rebound slot 83, springs back the width of slot 83 and the equal length of bushing 6.
The upper end of casing 8 is provided with the first flange, which, which is turned over downwards, constitutes top bar 81.The upper end of stock 2
It is provided with the second flange 2a, second flange 2a, which is turned over downwards, is close to the first flange.The width phase of first flange and the second flange
Deng.
In the inner hole of the upper end insertion driving wheel 9 of stock 2.Driving wheel 9 is axially disposed a locating slot 9a, stock 2 it is upper
End cooperates with locating slot 9a.
Obviously, in above structure, due to bearing insert 6, bearing block 1b, bearing cap 3 and effect by wheel seat 4, first axle
Hold 5 and second bearing 7 will not generate axial movement.Due to 82 and first top bar 81 that constitutes of flange of getting out of a predicament or an embarrassing situation of casing 8
Effect, casing 8 will not generate axial movement.Since the second flange 2a is close to the first flange, and casing 8 and 2 interference of stock
Cooperation, therefore the axial movement of stock 2 is also locked.Be especially considering that during devices work common Impact direction and
Stress size, such structure are enough to keep the good opposite instrument seat 1 of stock 2 fixed.
Further, it due to the setting of rebound slot 83, after stock 2 is interference fitted with casing 8, will be returned at rebound slot 83
Bullet forms step effect, to further limit the axial movement of stock 2.
On the other hand, due to the effect of the first flange and the second flange, stock 2 and casing 8 are interference fitted, casing 8 and the
One bearing 5 and second bearing 7 are interference fitted, and the upper end of stock 2 and locating slot 9a cooperate, therefore stock 2 and casing 8 and drive
The rotational angular velocity of driving wheel 9 is consistent.
The top of driving wheel 9, which is provided with, fastens step 9b, and the top of stock 2 is provided with fastening corresponding with step 9a is fastened
Face 2b.Therefore the top reverse step fastening for fastening step and stock inside driving wheel 9, prevents driving wheel from deviating from, is also prevented from
Stock is drawn out.
The long boom end fixed structure of surgical operation auxiliary robot instrument can be applied to surgical operation auxiliary robot instrument.
Corresponding, the utility model additionally provides a kind of surgical operation auxiliary robot instrument stock end fixing method,
The following steps are included:
1) selection one and the matched casing of stock, circumferentially setting springs back slot to the inner hole in the middle part of casing;Match stock interference
Together in casing;
2) the first flange is set in the upper end of casing, and first flange is made to be turned over downwards composition step structure;In casing
Lower end be arranged step structure;
The second flange is set in the upper end of stock, second flange is made to be turned over downwards the upper table for being close to first flange
Face;
3) first bearing and second bearing are arranged by bushing interval in instrument;Make the first flange against first bearing
Upper surface;Make the step of lower end against the lower end surface of second bearing.
Preferable embodiment is, in step 1), makes to spring back the width of slot and the equal length of bushing.
The preferred embodiments of the present invention have been described in detail above.It should be appreciated that the ordinary skill people of this field
Member according to the present utility model can conceive without creative work makes many modifications and variations.Therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality according to the design of the utility model on the basis of existing technology in domain
Available technical solution is tested, it all should be within the scope of protection determined by the claims.
