Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1 and fig. 2, the embedded structure of end face balls 6 of the welding and polishing machine comprises a rotating disc 1, a plurality of workpiece shaft holes are arranged on the rotating disc 1, a workpiece spindle 2 is freely and rotatably arranged in the workpiece shaft holes, a clamp block 3 for clamping a workpiece is arranged at one end part of the workpiece spindle 2, a circle of first ring groove 4 is arranged on the bottom surface of the clamp block 3, a circle of second ring groove 5 is arranged on the surface of the rotating disc 1 around the workpiece shaft holes, a plurality of balls 6 are densely arranged in the second ring groove 5, the clamp block 3 is placed in the workpiece shaft holes along with the workpiece spindle 2, the bottom surface of the clamp block 3 is attached to the surface of a rotating shaft, the first ring groove 4 and the second ring groove 5 are correspondingly combined to form an annular channel, the cross section of the annular channel is circular, the size of the second ring groove 5 is larger than that the first ring groove 4, so that the balls, still fixed cover 8 is equipped with screw thread cylinder 7 on the work piece main shaft 2, still can dismantle on the screw thread cylinder 7 and be equipped with fixed cover 8, the trepanning has been seted up on the fixed cover 8, the internal thread has been seted up in the trepanning, the outer lane of screw thread cylinder 7 is equipped with the external screw thread, it fixes on screw thread cylinder 7 to make fixed cover 8 fix through the connection of internal thread and external screw thread, fixed cover 8 is fixed completely and is fixed the upper surface of fixed cover 8 behind screw thread cylinder 7 and the bottom surface laminating of carousel 1 but the contact surface between the two is in the lax state and can not produce the friction, it is used for preventing fixed cover 8 excessive spacing ring 9 of rotation still to be fixed being equipped with the round on the screw thread.
If the rotary connection between the rotary table 1 and the workpiece spindle 2 is completed in the form of the side additional bearing, the bearing connection part between the workpiece spindle 2 and the rotary table 1 can be subjected to shearing force, so that the bearing is easy to break after long-term use, but the design adopts the joint surface of the bottom surface of the clamp block 3 and the upper surface of the rotating shaft to transfer the mutual friction force of the bottom surface and the upper surface of the rotating shaft, and the ball 6 is arranged on the contact surface to change the sliding friction into more flexible rolling friction, so that the effect of the bearing can be achieved, and the stressed transverse surface is a transverse surface, so that the rotary table can not break compared with the bearing, and the service life is longer.
In the process of assembly, imbed work piece main shaft 2 in the work piece shaft hole, make first annular 4 lid to ball 6 on and with the cooperation of second annular, then pass through fixed cover 8 from the below through the screw thread form, it is spacing to carry out the axial with work piece main shaft 2, work piece main shaft 2 will be fixed and can not drop on carousel 1, it is clearance fit that the inner wall of work piece main shaft 2 and work piece shaft hole will carry out, promptly can not produce the friction between the two, and because the bottom surface of carousel 1 also is in the lax state with the top surface of fixed cover 8 so both can not produce the friction yet, friction factor is only in actually on the contact surface of carousel 1 and anchor clamps piece 3, it is exactly the fundamental purpose of this design that ball 6 further reduces frictional force on both directly set up.
In order to further improve the life-span, the carousel 1 of this design both sides all provide second ring groove 5 and ball 6, and after the practical life-span of ball 6 in one side was used up, adopt the another side to assemble and can use again, and this kind of design enables carousel 1 and work piece main shaft 2's life-span to be approximately up to the twice.
