Embodiment Construction

[0010] The present invention will be described in further detail below by means of specific embodiments:

[0011] The reference signs in the drawings of the specification include: indexing plate 1, upper gear ring 2, lower gear ring 3, support base 4, main shaft 5, grooved disc 6, roller 7, dial 8, drum cam 9, base 10, pendulum 11.

[0012] The embodiment is basically as attached figure 1 Shown: In the indexing and positioning mechanism of this embodiment, the support seat is in the shape of a frame, and the support seat includes two vertical legs and a top cover integrated with the two legs. Through the guide hole, the upper end of the main shaft fixes the indexing plate through interference fit, the lower part of the indexing plate fixes the upper gear ring, and the upper part of the support base fixes the lower gear ring. When the indexing plate is positioned, the upper gear ring and the lower gear ring The toothed rings mesh, and when the indexing plate rotates and index...

Abstract

The invention discloses an indexing positioning mechanism which comprises a horizontal indexing plate. The indexing plate is fixed to a vertical main shaft. The indexing positioning mechanism is characterized in that the main shaft can reciprocate in the vertical direction; a horizontal groove disc is fixed to the main shaft; a driving plate capable of driving the groove disc to rotate is arranged in the side direction of the groove disc; the indexing positioning mechanism further comprises a supporting seat arranged below the indexing plate; a lower toothed ring is arranged on the upper portion of the supporting seat; the lower toothed ring is provided with an upper toothed ring in a meshed manner; and the upper toothed ring is fixed to the lower portion of the indexing plate.

Description

technical field [0001] The invention relates to the indexing and positioning technology of the indexing plate of a machine tool, in particular to an indexing and positioning mechanism. Background technique [0002] The indexing plate is a machine tool accessory that clamps the workpiece on the chuck or between two centers, and makes it rotate, index and position, and is mostly used in automation equipment. The indexing and positioning of the indexing plate are realized by the indexing and positioning mechanism. The indexing and positioning mechanism is usually used in the indexing processing of the workpiece, especially the circumferential drilling of the workpiece. The positioning of the existing indexing and positioning mechanism is usually realized by the ratchet pawl. The pawl clamps the ratchet under the auxiliary action of the spring to realize the positioning of the indexing plate. Positioning is by means of detents. The above-mentioned indexing and positioning mech...
