Detailed Description
Referring first to fig. 3, a double pendulum milling head patent previously filed by the applicant is described, wherein the double pendulum milling head patent comprises an upper unit and a lower unit. The upper unit comprises an alternating current permanent magnet synchronous outer rotor motor C1 which is vertically arranged, a rotating shaft part 104 which is fixedly connected with a rotor of the motor C1, and a fast assembly 101 which is fixedly connected with the lower end of the rotating shaft part 104; the rotor of the motor C1 also has associated therewith a sensing unit for defining a rotation angle for driving the motor in reciprocating rotation.
In fig. 3, the lower unit comprises a milling head, a cross hollow shaft 3 for mounting the milling head motorized spindle 2; alternating current permanent magnet synchronous outer rotor motors A1 and A2 are symmetrically arranged at two ends of the cross hollow shaft 3 in the A axis direction, and windings of the two horizontal motors are connected in series, so that the cross hollow shaft 3 is synchronously driven to drive the milling head to swing around the A axis. The lower unit also comprises a left ear piece 103' and a right ear piece 103 which are respectively and fixedly connected with the stators of the horizontal torque machines A1 and A2. Left and right ears 103', 103 are attached to the upper lower quick mount assembly 102. The rotor of one of the horizontal vertical torque motors A1 and A2 is also associated with an encoder for accurately positioning the swing angle of the milling head around the axis A.
In order to realize the connection between the upper and lower units in fig. 3, the upper quick-assembly component 101 and the lower quick-assembly component 102 constitute the quick-change structure of the present invention, which comprises a joint, a long pin, a short conical surface, a stud bolt, and an end face key, which are cooperatively arranged in the components. The quick-change structure and the method of the utility model are particularly suitable for the double-pendulum milling head shown in figure 3.
Referring to fig. 1, the quick-change structure of the present invention is described with reference to fig. 2. For the dismounting and assembling structure, firstly, the electric connectors, the oil passages and the cooling water passages are designed for the electric connectors, the oil passages and the cooling liquid, and the male connectors 63 and the female connectors 64 distributed on two units are generally adopted.
The utility model discloses still need set up the long round pin 65 as the butt joint guide body in the coupling assembling of upper and lower unit, when there is the deviation in the picture when double pendulum cutter head A axle body position, the long round pin can't insert the post hole on another unit, therefore the A axle body can't dock with the C axle. At this time, the long pin protects the joint from collision. In the figure, the size of the lower part of the long pin is smaller than that of the upper part, because the long pin is not required to be used for guiding after the electric joint is butted with the oil way and the cooling water way joint, and the long pin only needs to play a role in coarse positioning.
In order to realize accurate positioning, the utility model discloses a short awl and plane location mode (62 as shown in fig. 2), because the conical surface and the plane of short awl have realized all restraints except that C axle gyration, consequently above-mentioned long round pin lower part size is less than the upper portion size, can avoid crossing the location problem.

The utility model discloses a stud, the one end snap-on of double-screw bolt is in the screw hole that A axle body is connected the face, and the other end passes the bolt hole on the C axle body is connected the face, screws up at the bolt hole nut for the other end, with diaxon body zonulae occludens, not only connects simple and easy, convenient but also stable, reliable like this.
The C-axis transmits torque to the A-axis body by using the end face key technology. The end face key 61 restricts the degree of freedom in the C-axis rotation direction. In order to facilitate the replacement of the shaft body of the A shaft of the double-pendulum milling head, the motion precision of the shaft body of the A shaft in the direction of the C shaft is prevented from being influenced by the reverse clearance between keys, so that a matching processing form is adopted. The double-pendulum milling head is machined, the end face key is machined, the shaft body A and the shaft body C are connected after the double-pendulum milling head is assembled, the shaft body A is replaced as the shaft body A during operation, the two bodies are locked by the double-end stud and then are integrally placed into a machine tool, and the key groove is machined in the radial direction of the joint surface of the two bodies according to the size of the end face key which is machined, so that the transmission precision can be guaranteed.
The above description is only the specific implementation manner of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution of the present invention and the design of the present invention within the technical scope of the present invention.
