Example Embodiment

[0021] Such as Figure 1 to Figure 3 As shown, the lathe spindle indexing and locking mechanism includes an indexing plate fixed relative to the lathe spindle 5, an indexing plate positioning mechanism for locking and unlocking the position of the indexing plate, a brake disc 3 fixed relative to the lathe main shaft, and the brake discs respectively. Brake pads 12 on both sides and a brake pad drive mechanism that makes the two brake pads move closer or farther away. Both the axis of the index disc and the axis of the brake disc coincide with the axis of the main shaft of the lathe.

[0022] The index plate is the ring gear 1, and the index plate positioning mechanism includes a rack 6 matched with the ring gear and a rack moving mechanism that enables the rack to mesh or disengage from the gear ring. The rack moving mechanism includes a base 9 fixed on the headbox 11, an adjusting screw 8 passing through the base, and a guide post 7 for guiding the rack to move. The adjusting s...

Abstract

The invention provides a lathe spindle indexing locking mechanism. The lathe spindle indexing locking mechanism comprises an index plate which is fixed relative to a lathe spindle, an index plate positioning mechanism which achieves locking and unlocking of the index plate, a brake disc which is fixed relative to the lathe spindle, brake blocks which are respectively arranged on bilateral sides of the brake disc and a brake block driving mechanism which enable the two brake blocks to get close or be far from each other; an axis of the index plate and an axis of the brake disc and an axis of the lathe spindle are coincided. After a workpiece is lathed, positioning of the index plate is achieved through the index plate positioning mechanism, the brake block driving mechanism drives the two brake blocks to be close to the brake disc to achieve braking, the lathe spindle achieves locking positioning, a first key groove or hole is machined through a milling head or drill bit, the two brake blocks are separated after machining, the position of the index plate is unlocked, the spindle rotates to a next key groove or hole machining position of the workpiece, the index plate is positioned, the brake plate achieves braking to machine the next key groove or hole until all key grooves or holes are machined.

Description

technical field [0001] The invention relates to an indexing locking mechanism for a lathe spindle. Background technique [0002] With the development of industrial fields such as automobiles, national defense, mining, agriculture, and construction machinery, higher and higher requirements are placed on the precision and efficiency of machined parts. Manual marking is required, and equipment such as milling machines and drilling machines are added, so that after the workpiece is turned on the lathe, it is transferred to the milling machine or drilling machine for secondary clamping, and when the workpiece is large, the purchase cost and processing cost of the milling machine or drilling machine are very high. The processing method is low in efficiency, poor in safety, high in cost and poor in precision. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an indexing and locking mechanism for a lathe spindle ...
