Abstract
The utility model relates to a swing mechanism for a numerical control vertical internal and external grinding machine planker, which comprises a linear guide rail, a guide rail sliding block, a roller collar, a ball screw nut, a ball screw, a double-row roller collar, a planker and a planker base, wherein a servo motor, a ball screw nut pair and the ball screw are mounted at one end at the top of the planker base; the linear guide rail is mounted on a transition plate, and is fixed on the outer ring of the roller collar through the transition plate; the inner ring of the roller collar is fixedly connected with the ball screw nut; the guide rail sliding block is fixed on the planker; the other end of the planker base is rotationally connected with the planker through the double-row roller collar. Compared with the traditional swing mechanism in which the swing movement is realized by a worm and gear structure, and based on the realization of swing of a large-scale numerical control vertical internal and external grinding machine planker, the swing mechanism for the numerical control vertical internal and external grinding machine planker, provided by the utility model, on account of the fact that a swing driving point is far from the swing center, has the advantages that the positioning accuracy and the repeated positioning accuracy are good, reverse gap and ineffective motion are improved, accuracy loss caused by abrasion and the like is reduced, and the cost is lower.
Description
Technical field
The utility model relates to a kind of planker slew gear of digital control vertical internal and external grinding machine.
Background technology
At present, the digital control vertical internal and external grinding machine planker revolution that domestic manufacturer produces adopts the slew gear of this frame for movement of worm and gear as planker mostly.Complex structure, processing and assembly cost are all higher, and rotating accuracy to be turned round drive point Accuracy larger.
Summary of the invention
In order to realize the high-precision rotary of digital control vertical internal and external grinding machine planker, the utility model provides a kind of digital control vertical internal and external grinding machine planker slew gear, this mechanism can make planker turn round certain angle along the centre of gyration, thereby is with rotary bistrique revolution, has expanded the range of application of vertical grinding.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of digital control vertical internal and external grinding machine planker slew gear, comprise line slideway, guide rail slide block, transition disc, the roller axle collar, ball-screw nut, ball-screw, the dual-row rollers axle collar, planker, planker base, clamping cylinder, be characterized in: planker base top one end is provided with servomotor and ball guide screw nat and ball-screw, line slideway is installed on transition disc, line slideway is fixed on roller axle collar outer ring by transition disc, roller axle collar inner ring is connected with ball-screw nut, and guide rail slide block is fixed on planker; The planker base other end is connected with planker by the dual-row rollers axle collar.
Between the inner ring of the single-row roller axle collar and ball-screw nut, feel relieved and be connected by centring sleeve.
Planker is fixedly connected with the inner ring of the dual-row rollers axle collar, and feels relieved by centring sleeve between the inner ring of the dual-row rollers axle collar and planker; Described planker base is fixedly connected with the outer ring of the dual-row rollers axle collar.
In the time that planker is turned back to target location, described planker clamps locking by clamping cylinder.
The beneficial effects of the utility model are:
Due to drive point and swivel point distant, therefore the positioning precision of this mechanism and repetitive positioning accuracy are better.And can improve backlass and lost motion;
2. cost is lower compared with traditional worm and gear revolving structure, is more suitable for huge revolving indexing mechanism;
3. the Accuracy that the factor such as wearing and tearing is brought is less.
Revolving structure of the present utility model, compared with the common mechanism that is used in vertical internal and external grinding machine planker rotation, cost is low, and precision is high.
Brief description of the drawings

Fig. 2 is the partial enlarged drawing at A place in Fig. 1;
Fig. 3 is the partial enlarged drawing at B place in Fig. 1;
Fig. 4 is the rotation diagram of analysing and observe along A-A in Fig. 1;
Fig. 5 is the right view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As shown in Figures 1 to 5, a kind of digital control vertical internal and external grinding machine planker slew gear, comprises line slideway 1, guide rail slide block 2, transition disc 3, the roller axle collar 4, centring sleeve 5, roller screw nut 6, roller screw 7, centring sleeve 8, the dual-row rollers axle collar 9, pad 10, planker 11, planker base 12, clamping cylinder 13.
From Fig. 4, in the time that ball-screw nut 7 is moved to the left along level, ball-screw nut 6 moves together with the roller axle collar 4 inner rings, the roller axle collar 4 relative roller axle collar 4 inner rings in outer ring are rotated counterclockwise along a axle, because planker 11 is connected with the roller axle collar 4 outer rings, and be connected with planker base 12 by centring sleeve 8, therefore do turning anticlockwise from Fig. 5 planker 11 along gyroaxis.In like manner, in the time that ball-screw nut 7 moves right along level, the relative roller axle collar 4 inner rings in roller axle collar outer ring turn clockwise along a axle, do clockwise revolution from Fig. 5 planker 11 along gyroaxis.
In the time that being turned back to target location, planker 11 clamps latched position with clamping cylinder 13.
