Claims

[Claims for Utility Model Registration] A table for mounting a workpiece, which is rotatably and vertically supported by the base and has a plurality of horizontal cam followers arranged on the same circumference at equal angles on the lower surface. , a rocking plate having a forward L-shape, the bent portion of which is pivotally connected to the base with horizontal pins, and a vertical cam follower is pivotally connected to the upper end of the vertical piece; a lever that is pivotally connected to the base with a pin, and is configured to push up the table by rotating around the pin; an upper end is pivotally connected to the rear end of the lever, and a lower end is A continuous piece pivotally attached to the front end of the horizontal piece of the rocking plate is provided between the base and the table, and when the table is lowered, they engage with each other to fix the table, and when the table is raised, they engage with each other and fix the table. , a coupling ring adapted to disengage from the engagement, and a cam groove fixed to a camshaft rotated by a motor and cut into the circumferential surface engage with the horizontal cam follower, and as the camshaft rotates, A first cam adapted to rotate the table; and a cam groove fixed to the camshaft and cut into the circumferential surface engages with the vertical cam follower, and by rotation of the camshaft, the rocking plate The second part is adapted to raise and lower the table via the continuous piece and the lever.
Normally, the motor is stopped and the table is lowered; when the motor is started, the table rises and starts rotating; once the table has rotated a predetermined angle, the table stops rotating. The index table is characterized in that the size and shape of each of the cam grooves are determined so that the cam grooves are moved downward after the index table is moved.
