The utility model content
The utility model has overcome shortcoming of the prior art, and a kind of pulley structure that is used for the numerical control four-axis drilling and milling machine is provided, and its electric main shaft is regulated easily by motor, worm gear control angle, and the anglec of rotation is controlled easily.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of pulley structure that is used for the numerical control four-axis drilling and milling machine, comprise coaster and electric main shaft, this electricity main shaft is provided with the brill milling cutter, is provided with between described coaster and the electric main shaft to drive the gear that above-mentioned electric main shaft rotates, and also is provided with on this coaster and drives endless screw apparatus and the servomotor that this gear rotates.
Further, described coaster is provided with first containing hole, and described gear is provided with this first containing hole.
Further, described coaster is provided with second containing hole, and described endless screw apparatus is located in this second containing hole.
Further, described gear comprises the main shaft connecting plate affixed with above-mentioned electric main shaft, and this main shaft connecting plate connects first worm-wheel shaft, worm gear, angular contact ball bearing, inner spacing collar, gland, piston, piston cylinder and guide finger successively.
Further, be provided with dust cap outside the described main shaft connecting plate.
Further, described endless screw apparatus comprises inner spacing collar, worm screw, second worm-wheel shaft and connecting plate for electric motor.
Further, described coaster rear portion is provided with guide rail and the tooth bar that coaster is moved up and down.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is simple in structure, and compact, stressed evenly because the transmission of worm gear and worm screw, angle orientation is accurate, electric main shaft fixation, and the cutting vibration of brill milling cutter is little, and is convenient to maintenance, adjustable gaps.
