Description
technical field:
The utility model belongs to machine tool equipment field, relates to a kind of lathe zero-clearance transmission mechanism, particularly relates to a kind of zero-clearance transmission mechanism being applicable to high-precision numerical control machine feeding slide unit.
background technology:
At present, the raising required processing precision of products and working (machining) efficiency along with enterprise and user, machine tool equipment manufacturing enterprise is also improving constantly the requirement of the Design and manufacture of precise machining equipment.In Digit Control Machine Tool slide unit parts, motor movement and power are transmitted in the effect of transmission device, and the quality of its transmission performance determines machining accuracy and the working (machining) efficiency of whole lathe.Compared with other drive mechanism, gear drive has that compact conformation, smooth running, transmitting torque are large, low noise advantages, is therefore widely used in machine tool sliding table transmission mechanism.Without the mechanism of disappear gap or adjustment gears meshing sideshake in traditional gear drive, its advantage is that structure is simple, and be convenient to manufacture and assembling, shortcoming can produce return difference, vibration & noise in transmission process, thus affect the machining accuracy of lathe, be not suitable for high-precision numerical control machine feeding slide unit; Traditional gear and axle are connected by key and transmit power, and advantage is that transmitting torque is comparatively large, manufacture and assembling simple, but return difference, vibration & noise can be produced in transmission process, not be suitable for high-precision numerical control machine feeding slide unit.Therefore, in order to adapt to the requirement of high accuracy processing, it is completely necessary for needing high, the transmitting torque of a kind of transmission accuracy of development zero-clearance transmission mechanism that is large, that can be applicable to high-precision numerical control machine feeding slide unit badly.
utility model content:
The purpose of this utility model is that providing a kind of has higher transmission accuracy, larger transmitting torque, reduces or eliminates return difference, reduces vibration & noise, is applicable to the zero-clearance transmission mechanism of high-precision numerical control machine feeding slide unit.
The technical solution of the utility model is: the zero-clearance transmission mechanism being applicable to high-precision numerical control machine feeding slide unit, comprising: the first gear, expansion sleeve, screw, clamping sleeve, expansion sleeve, bolt, the second gear, leading screw, motor gear, servomotor, baffle ring, Screw, Compress Spring, half pin; Servomotor is connected with motor gear respectively by expansion sleeve, clamping sleeve, bolt, first gear and the second gear are respectively by screw, baffle ring, Screw, Compress Spring, partly sell connection, the first gear after connection is connected with leading screw by expansion sleeve with the second gear, and with motor gear tight mesh.
The utility model adopts after technique scheme can reach following beneficial effect: after adopting said structure, and between servomotor with motor gear, two plate gears are connected with all adopting expansion sleeve between leading screw; And two plate gears reach tight mesh by Compress Spring adjustment with motor gear, realize that transmitting torque is large, assembling and easy to adjust, reduce or eliminate return difference in transmission process, reduce vibration & noise.
accompanying drawing illustrates:
Fig. 1 is the sectional structure schematic diagram that the utility model is applicable to the zero-clearance transmission mechanism of high-precision numerical control machine feeding slide unit;
Fig. 2 is the A-A generalized section of Fig. 1.
detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is further described: as shown in Fig. 1 ~ 2: the zero-clearance transmission mechanism being applicable to high-precision numerical control machine feeding slide unit comprises: the first gear 1, expansion sleeve 2, screw 3, clamping sleeve 4, expansion sleeve 5, bolt 6, second gear 7, leading screw 8, motor gear 9, servomotor 10, baffle ring 11, Screw 12, Compress Spring 13, half pin 14.
Servomotor 10 is connected with motor gear 9 respectively by expansion sleeve 5, clamping sleeve 4, bolt 6, first gear 1 is connected respectively by screw 3, baffle ring 11, Screw 12, Compress Spring 13, half pin 14 with the second gear 7, the first gear 1 after connection is connected with leading screw 8 by expansion sleeve 2 with the second gear 7, and with motor gear 9 tight mesh.
During lathe work, servomotor 10 is rotated by bolt 6, clamping sleeve 4 and expansion sleeve 5 drive motor gear 9, by adjustment baffle ring 11, Screw 12, Compress Spring 13, half pin 14 carry out zero-clearance transmission with motor gear 9 through fixing the first gear 1 of screw 3 and the second gear 7, the first gear 1 and the second gear 7 drive leading screw 8 to rotate by expansion sleeve 2.Test proves, the zero-clearance transmission mechanism of slide unit has that transmission accuracy is high, transmitting torque is large, easy to adjust, reduce the performances such as vibration & noise.
