Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following further describes the technical solution of the present invention with reference to the drawings and the embodiments.

Referring to fig. 1-6, a centering rotary disk for processing a circular workpiece is shown, which comprises a rotary disk body 1 arranged on a machine tool workbench and provided with a clamping plane 1 a. The machine tool is preferably a vertical lathe (not shown), and the rotary table body 1 is horizontally arranged on the vertical lathe. A centering adjustment device for adjusting the circular ring and the rotating disk body 1 into a concentric fit structure is provided on the clamping plane 1a of the rotating disk body 1, and a fastening structure for fixing the circular ring is provided on the centering adjustment device. The circular ring (shown as 10 in the figure) to be machined is placed on the centering adjusting device, and is adjusted through the adjusting action of the centering adjusting device to be concentric with the rotating disk body 1, so that the problem that the circular ring rotates eccentrically due to the rotation of the rotating disk body 1 during machining is solved, the contact distance of a machining tool of the vertical lathe and the circular ring in a rotating state can be kept equal, and the machining precision is further guaranteed. Through fastener be with ring and rotary disk body 1 regulation concentric back, with ring fastening and rotary disk body 1 formation body structure as an organic whole, the ring of being convenient for follows the synchronous stable rotation of rotary disk body 1. The centering rotating disk solves the problem that the circular ring workpiece is difficult to center and clamp at present, improves the convenience of centering and clamping the circular ring workpiece, and can keep the processing precision at the same time.

Specifically, centering adjusting device includes and sets up along circumference interval adjustment mechanism on the clamping plane 1a realizes the centering of ring through a plurality of adjustment mechanism from a plurality of not equidirectional centering regulation, helps improving the accurate nature of ring centering regulation. As shown in fig. 3, each of the adjusting mechanisms includes a strip-shaped convex plate 2 disposed on the clamping plane 1a toward the center of the circle, a groove 21 is formed on the top surface of the strip-shaped convex plate 2 along the length direction of the strip-shaped convex plate, a centering spring 3 is fixedly disposed on the inner wall of one end of the groove 21 away from the center of the circle of the rotating disk body 1, a centering block 4 slidably embedded in the groove 21 is fixed to the other end of the centering spring 3, and the centering block 4 is higher than the surface of the strip-shaped convex plate 2. The specific assembly operation is as follows: the circular ring is placed on the strip-shaped convex plates 2, the circular ring is stably supported through the strip-shaped convex plates 2, the circular ring is separated from contact with the clamping plane 1a, and turning damage to the clamping plane 1a caused by contact of a machining cutter and the clamping plane 1a can be effectively avoided in the machining process. Each centering block 4 overcomes the elasticity of the centering spring 3 under the action of external force, so that each centering block 4 is positioned in the circular ring and contacts the inner wall surface of the circular ring, then the corresponding centering block 4 is tensioned under the balanced elastic action of the centering springs 3 at different positions and is tightly attached to the corresponding position of the inner wall of the circular ring (as shown in figure 5), under the action of the elastic force of the plurality of centering springs 3, the circular ring is driven to move on each strip-shaped convex plate 2 through the centering blocks 4, and under the condition that each centering spring 3 is restored to a balanced elastic telescopic state, the circular ring is positioned at a position concentric with the rotating disk body 1, so that the centering adjustment operation of the clamping position of the circular ring is realized, and the problem that the circular ring is difficult to center is greatly reduced.

In order to keep the centering block 4 sliding linearly, as shown in fig. 5, the side wall of the centering block 4 is symmetrically provided with a limiting protrusion 41, and the side wall of the groove 21 is provided with a limiting sliding groove 21a which is matched with the limiting protrusion 41 to slide. Through the limiting matching of the limiting sliding groove 21a and the limiting protrusion 41, the centering block 4 can slide linearly under the driving of the external force of the centering spring 3, and the defect that the centering position is inaccurate due to the fact that the centering block 4 is in contact with the inner wall of the circular ring and deflects is avoided.

In order to realize the fastening of the state after the centering adjustment of the circular ring, as shown in fig. 6, the fastening structure is that the corner lines on both sides of the top surface of the strip-shaped convex plate 2 are set as a transition slope structure a.
