Specific embodiment
As shown in Figure 1 and Figure 2, this utility model numerically controlled lathe buffer, is arranged on the main spindle box 10 of numerically controlled lathe Interior, it is provided with the spline shaft 2 as power input shaft in main spindle box 10, it is solid that spline shaft 2 passes through rolling bearing 16 It is scheduled in main spindle box 10 left side and middle wallboard, stretch out on the left of spline shaft 2 and be connected with belt pulley 1 outside main spindle box 10, spline Power transmission shaft 2 left side external part is spline structure, and belt pulley 1 is arranged on spline shaft 2 left end, transmits power, drives spline to pass Moving axis 2 rotates.
Numerically controlled lathe buffer includes colligator gear 8, inner attrition piece 6, outside friction disc 5, locking nut 3, adjusts Section nut 4, steady pin 15, spline shaft 2 right side of main spindle box 10 inner side is colligator gear 8 installation position, colligator gear 8 endoporus pass through the colligator tooth that two pairs of rolling bearings (i.e. rolling bearing 12 and rolling bearing 13) are arranged on spline shaft 2 Take turns on 8 installation positions, between rolling bearing 12 and rolling bearing 13, be provided with spacer 9.The left side of colligator gear 8 opens up There are at least three breach circumferentially uniformly arranged, the left side of colligator gear 8 offers and lacks everywhere in the present embodiment Mouthful.It is spline structure in the middle of spline shaft 2, the inner attrition piece 6 with splined hole is enclosed within colligator gear 8 left end spline shaft On spline outside 2, outside friction disc 5 is enclosed within outside inner attrition piece 6, and outside friction disc 5 right side is provided with and is lacked with colligator gear 8 left end Four pieces of double wedges of mouth phase clamping, outside friction disc 5 drives colligator gear 8 to rotate, and colligator gear 8 is engaged with respective gears, leads to Cross each power transmission shaft and the driving-chain of travelling gear composition drives main shaft 11 to rotate.
Adjusting nut 4 is enclosed within spline shaft 2, and steady pin 15 passes through adjusting nut 4 and spline shaft 2 will adjust Nut 4 is positioned at the left side of inner attrition piece 6, and locking nut 3 is coordinated in rotary moving by the screw thread with adjusting nut 4 right side Push against the left side of inner attrition piece 6.In the middle part of adjusting nut 4, wherein it is provided with the pin-and-hole running through its radial direction, spline shaft 2 is provided with The hole corresponding with pin-and-hole, steady pin 15 passes through the pin-and-hole of adjusting nut 4 and the hole of spline shaft 2 will adjust spiral shell Female 4 are positioned at inner attrition piece 6 left end face, and adjusting nut 4 left side is arranged in the prominent part of convex, and convex is provided with the groove of uniform arrangement Hole, locking nut 3 one end is pressed on the left side of inner attrition piece 6 by the screw thread cooperation with adjusting nut 4.By locking nut 3 adjust the torque that inner attrition piece 6 tightness controls transmission, after adjustment finishes, with steady pin 15 secured adjusted nut 4 Locking.The left side of colligator gear 8 caves inward and is provided with fixed groove, the anchor of spline shaft 2 and colligator gear 8 It is cased with two retainer ring being arranged side by side 7 between groove, between two retainer ring 7, be connected with steady pin 14.
In the part course of processing, because of the reasons such as artificial or machine failure, during knife rest accidental impact lathe, the main shaft in rotation 11 are acted on by external force, and mair motor is still working condition, and each power transmission shaft in main spindle box 10 and travelling gear can produce very big Impulsive force and moment of torsion, particularly power input shaft (i.e. spline shaft 2) moment of torsion is bigger, and power input shaft is installed buffer unit Afterwards, when there being accidental impact to occur in the course of processing, spindle end is subject to great impulsive force, and impulsive force also passes to buffer simultaneously On the travelling gear of device, interior outside friction disc 5 is anxious because the torque demand of travelling gear increases suddenly in moment of torsion transmittance process Speed is skidded, and the impact suffered by each power transmission shaft and pitch wheel is instantaneously buffered, due to not reaching damage parts Intensity and make part obtain protection, thus being effectively protected the safety of each power transmission shaft and gear in main spindle box 10, improve machine The performance of bed.
