Description
Technical field
The utility model relates to a kind of stepless speed change device for the automatic lathe camshaft.
Background technology
The structure of the speed change gear of present employed automatic lathe camshaft as shown in Figure 3, it passes through a motor 1 and many group belt pulleys 2, on each belt pulley 2 a plurality of belt grooves are arranged, realize changing the speed change of automatic lathe camshaft by the position that changes belt 3 belt grooves in belt pulley 2.Its shortcoming is: because the diameter of belt grooves is relatively constant in the belt pulley 2, so the speed change of camshaft 4 changes step by step, can not realize arbitrarily governing speed; Must shut down first when carrying out speed governing such as need, again start behind the complete belt to be replaced, whole process is cumbersome, consumes workman's adjusting machine time.
The utility model content
Technical problem to be solved in the utility model is: the stepless speed change device that is used for the automatic lathe camshaft that any adjustment cam axle of a kind of energy speed is provided.
For addressing the above problem, the technical solution adopted in the utility model is: a kind of stepless speed change device for the automatic lathe camshaft, comprise middle seat, be provided with power transmission shaft in the middle seat, be provided with gear-box on the described middle seat, be provided with servo motor on the gear-box, gear-box comprises and middle the seat casing that fixes and the case lid that is connected with casing, the inside of casing is provided with groove, be provided with intermeshing driving gear and the first travelling gear in the groove, the driving shaft of servo motor stretches into gear-box inside and driving gear is arranged on the driving shaft of servo motor, the first travelling gear center is provided with gear shaft, the end of gear shaft is stretched out on casing and its and is provided with the second travelling gear, is provided with driven gear on the power transmission shaft, and driven gear is meshed with the second travelling gear.
The beneficial effects of the utility model are: the above-mentioned stepless speed change device that is used for the automatic lathe camshaft, it is simple in structure, easy to use, maintenance is easy, with low cost.It is the speed of adjustment cam axle arbitrarily, realize electrodeless variable-speed, has reduced the trouble that the workman operates lathe, has improved production efficiency.

Among Fig. 3: 1, motor, 2, belt pulley, 3, belt, 4, camshaft.
The specific embodiment
Be described in further detail below by the stepless speed change device of specific embodiment to the utility model automatic lathe camshaft.
Such as Fig. 1, shown in Figure 2, a kind of stepless speed change device for the automatic lathe camshaft, comprise middle seat 1, be provided with power transmission shaft 2 in the middle seat 1, be provided with gear-box on the described middle seat 1, be provided with servo motor 3 on the gear-box, gear-box comprises and middle seat 1 casing that fixes 4 and the case lid 5 that is connected with casing 4, the inside of casing 4 is provided with groove 6, be provided with intermeshing driving gear 7 and the first travelling gear 8 in the groove 6, the driving shaft of servo motor 3 stretches into gear-box inside and driving gear 7 is arranged on the driving shaft of servo motor 3, the first travelling gear 8 centers are provided with gear shaft 9, the end of gear shaft 9 is stretched out on casing 4 and its and is provided with the second travelling gear 10, is provided with driven gear 11 on the power transmission shaft 2, and driven gear 11 is meshed with the second travelling gear 10.
Operation principle of the present utility model is: during use, servo motor 3 drives driving gear 7 and rotates, because driving gear 7 is meshed with the first travelling gear 8, driving gear 7 drives the first travelling gear 8 and rotates, thereby driven gear axle 9 rotates, and namely the second travelling gear 10 rotates, because driven gear 11 is meshed with the second travelling gear 10, the second travelling gear 10 drives driven gear 11 and rotates, and rotates thereby drive power transmission shaft 2.The purpose that can realize regulating power transmission shaft 2 rotating speeds by the rotating speed of regulating servo motor 3, because the triggered time of servo motor 3 is in 0.1 second, so it is the speed of adjustment cam axle arbitrarily, reduced the trouble that the workman operates lathe, improved production efficiency.
The above embodiments are principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used for restriction the utility model; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
