The stepless speed change device is simple in structure, convenient to use, simple and convenient to maintain and low in cost. In addition, the speed of the camshaft can be optionally adjusted, troubles for workers in operating a machine tool are reduced, and production efficiency is improved.
Description
Technical field
The present invention relates to a kind of stepless speed change device that is used for the automatic lathe camshaft.
Background technology
The structure of the speed change gear of present employed automatic lathe camshaft is 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 through the position that changes belt 3 belt grooves in belt pulley 2.Its shortcoming is: because the diameter of belt grooves is constant relatively in the belt pulley 2, so the speed change of camshaft 4 changes step by step, can not realize governing speed arbitrarily; Must shut down earlier when carrying out speed governing like need, start again behind the intact belt to be replaced, whole process is cumbersome, consumes workman's adjusting machine time.
Summary of the invention
Technical problem to be solved by this invention is: the stepless speed change device that is used for the automatic lathe camshaft that any adjustment cam axle of a kind of ability speed is provided.
For addressing the above problem, the technical scheme that the present invention adopts is: a kind of stepless speed change device that is used for the automatic lathe camshaft comprises middle seat; Be provided with power transmission shaft in the middle seat, said middle seat is provided with gear-box, and gear-box is provided with servo motor; Gear-box comprises and middle seat casing that fixes and the case lid that is connected with casing; The set inside of casing is fluted, is provided with the intermeshing driving gear and first travelling gear in the groove, and 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 stretches out casing and it is provided with second travelling gear, and power transmission shaft is provided with driven gear, and driven gear is meshed with second travelling gear.
The invention has the beneficial effects as follows: 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, realizes electrodeless variable-speed, has reduced the trouble that the workman operates lathe, has improved production efficiency.

The specific embodiment
Through specific embodiment the stepless speed change device of automatic lathe camshaft of the present invention is done further to describe in detail below.
Like Fig. 1, shown in Figure 2, a kind of stepless speed change device that is used for the automatic lathe camshaft, seat 1 in comprising; Be provided with power transmission shaft 2 in the middle seat 1, said middle seat 1 is provided with gear-box, and gear-box is provided with servo motor 3; Gear-box comprises and middle seat 1 casing 4 that fixes and the case lid 5 that is connected with casing 4; The set inside of casing 4 is fluted 6, is provided with the intermeshing driving gear 7 and first travelling gear 8 in the groove 6, and 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; First travelling gear, 8 centers are provided with gear shaft 9; The end of gear shaft 9 stretches out casing 4 and it is provided with second travelling gear 10, and power transmission shaft 2 is provided with driven gear 11, and driven gear 11 is meshed with second travelling gear 10.
Operation principle of the present invention is: during use, servo motor 3 drives driving gear 7 and rotates, because driving gear 7 is meshed with first travelling gear 8; Driving gear 7 drives first travelling gear 8 and rotates; Thereby driven gear axle 9 rotates, and promptly second travelling gear 10 rotates, because driven gear 11 is meshed with second travelling gear 10; 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 through 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 the principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used to limit the present invention; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, these all belong to protection scope of the present invention.
