Description
Technical field
The utility model relates to a kind of actuator linkage for tooth milling machine.
Background technology
Mill teeth is method of forming milling, can process straight-tooth, helical teeth, bevel gear and tooth bar etc.The basic demand of Gear Processing ensures that profile of tooth is accurately even with point tooth.During mill teeth, a point tooth evenly relies on dividing head to ensure, profile of tooth ensures mainly through the profile of milling cutter.The equipment of Gear Milling is tooth milling machine, when mill teeth, the motion of milling cutter has self rotary motion and straight-line feed motion, general rotary motion is driven by a power, feed motion is driven by another power, and the main deficiency that existing tooth milling machine exists is: during Milling Process, needs to open respectively the power driving milling cutter to rotate and the power driving milling cutter feeding, inconvenient operation, working (machining) efficiency is low.
Utility model content
The utility model is intended to the actuator linkage for tooth milling machine of the power interlock providing a kind of power driving milling cutter to rotate and drive milling cutter feeding.
The actuator linkage for tooth milling machine in this programme, comprise driving shaft, one end of driving shaft is connected with the output shaft of the first power, the other end of driving shaft is provided with active friction disk, driven friction disk can be provided with by frictional drive with active friction disk, driven friction disk is provided with main distributing shaft, main distributing shaft is connected with cutter shaft, driving shaft is also provided with driving gear, that engages with driving gear is provided with driven gear, driven gear is fixed on auxiliary distributing shaft, auxiliary distributing shaft is provided with cam, microswitch is provided with in the side direction of described cam, cam can touch microswitch contact when rotating starts microswitch, microswitch is connected on the electric loop of the second power, second power is the feeding power of milling cutter.
Principle of the present utility model and beneficial effect as follows: the first power is the rotary power of milling cutter self, after starting the first power, under the drive of the first power, driving shaft rotates, active friction disk and driven friction disk engage, under the effect of the frictional force of active friction disk and driven friction disk, drive main distributing shaft to rotate, main distributing shaft band movable arbor rotates, and cutter shaft drives milling cutter to rotate; Simultaneously, the driving gear be arranged on driving shaft drives driven gear to rotate, driven gear band moving cam rotates, after cam turns over certain angle, the contact of touching microswitch, is started microswitch, is started the electric loop of the second power by microswitch, and then start the second power, drive milling cutter feeding.
By scheme of the present utility model, only need one-shot to drive the power of milling cutter rotation, just can start the power driving milling cutter feeding simultaneously, the interlock realized between two power starts, easy to operate, can improve working (machining) efficiency.
Further, also comprise a fork, one end of described fork is provided with hook, and be provided with draw-in groove at the dish edge of driven friction disk, described hook can be connected in draw-in groove, and the middle part of fork is hinged on a back shaft, and the other end of fork is driven by the 3rd power and swings up and down.When needs are shut down; one end with the fork of hook declines; hook is made to block draw-in groove on driven friction disk; main distributing shaft is stopped operating; disconnect the first power simultaneously; avoid directly disconnecting the first power, main distributing shaft reacts on the first power because having rotator inertia and being rotated further, and easily damages the problem of the first power.
Further, be provided with a connecting axle in the below of fork near the side of hook, one end of connecting axle and an extension spring is fixed, and the other end of extension spring is fixed on bearing pin that fork is arranged.During mill teeth, under the effect of the 3rd power, fork upwards lifts all the time with one end of hook, but when quitting work, extension spring plays the effect of reset to fork, makes hook block driven friction disk.
Further, the 3rd power is electromagnet, and the top of electromagnet is provided with can at the connecting rod of vertical direction motion, the end of connecting rod and the end of described fork hinged.Electromagnet is as power, and compared to power such as cylinders, structure is simple, and cost is low.
