Abstract
The utility model discloses a transmission and rotation connecting device on a plane grinding machine. The transmission and rotation connecting device comprises an air cylinder piston rod, a data line tube, a speed reduction motor and an upper main shaft, the piston rod on an air cylinder and a hollow shaft sleeve are locked through locking nuts when assembled, a data line support is arranged in the vertical direction of the hollow shaft sleeve, and the upper main shaft is fixed through thrust bearings, bolts for adjusting cushions and end covers, wherein the thrust bearings and the bolts are placed in a bearing seat. Parts above the air cylinder are all covered with a protective cover, the appearance is attractive, meanwhile, it is guaranteed that a bearing in a coupling can be stressed evenly and rotate stably, the hidden danger that a lathe vibrates is eliminated, and the stability and the machining precision of the lathe are improved.
Description
Technical field:
The utility model relates to a kind of transmission and rotary joint apparatus, is specially adapted to coil while pressurizeing and use on face lapping mill.
Background technology:
Twin grinder has upper and lower two bistriques, and it is to be provided for upper bistrique by cylinder that upper bistrique provides operating pressure, and because self-condition restriction is not suitable for rotating, lower bistrique rotates, and is to provide rotary power by reductor.Its shortcoming is: because grinder exists upper dish bias and vibration hidden danger, affect machine finish, reduce user's grinding efficiency or cause equipment normally to use.
Summary of the invention:
Task of the present utility model is to propose a kind of elimination lathe to vibrate, and avoids transmission and rotary joint apparatus on a kind of face lapping mill of eccentric rotary generation.
Task of the present utility model completes like this, transmission on a kind of face lapping mill and rotary joint apparatus, it comprises cylinder piston rod, data spool, reducing motor and upper main shaft, it is characterized in that: the piston rod on cylinder and the assembling of hollow shaft sleeve are to lock by locking nut, vertical direction at hollow shaft sleeve is equipped with data wire support, and upper main shaft is fixed with bolt and end cap by thrust bearing and the adjusting pad placed in bearing block.
The utlity model has following effect: the utility model is that the parts of the above part of cylinder are all covered with guard shield, appearance looks elegant, can guarantee bearing pressurized in shaft coupling all even rotary flat is steady simultaneously, eliminate lathe the hidden danger of vibration has occurred, thereby improved stability and the machining accuracy of lathe.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Drawing explanation: 1, piston rod, 2, locking nut, 3, hollow shaft sleeve, 4, data wire support, 5, data spool, 6, end cap, 7, adjusting pad, 8, thrust bearing, 9, bearing block, 10, upper main shaft, 11, reducing motor.
The specific embodiment:
In conjunction with above accompanying drawing, describe embodiment in detail, cylinder is fixed by support, piston rod 1 on cylinder and the assembling of hollow shaft sleeve 3 are to lock by locking nut, operating pressure is provided by described cylinder, rotation for limited piston bar and hollow shaft sleeve, vertical direction at hollow shaft sleeve 3 is equipped with data wire support 4, described cylinder changes single rod solid shafting Standard Cylinder into by existing pair of rod air-cored axis cylinder, output shaft on reducing motor 11 is connected by reducing motor rotary power is provided with upper main shaft 10, upper main shaft has possessed pressure and two characteristics of rotation simultaneously, upper main shaft is by the thrust bearing 8 of 9 li of placements of bearing block, adjusting pad 7 use bolts and end cap 6 are fixing, the technical program has increased adjusting pad and has guaranteed the depth of parallelism, 6 two effect end faces of end cap are that grinding clamped one time completes processing, guarantee two face depth of parallelisms, make the pretightning force of thrust bearing 8 reach necessary requirement, better bear the active force of vertical direction, thereby guaranteed the concentric of two links of coupling mechanism, also just guaranteed the concentric of piston rod 1 and upper main shaft 10, avoided the generation of eccentric rotary.The data wire that prior art need to be drawn from cylinder top in order to simplify air cylinder structure, the data wire that changes 5 li of dresses of data spool into is to draw from tapping, and data wire length of tube is shortened, and has reduced installation and maintenance difficulty, reduce the height of lathe simultaneously, thereby facilitated shipment and transportation.
