Embodiment Construction

[0013] Referring to the accompanying drawings, a new numerically controlled indexing workbench for a horizontal machining center includes an upper saddle 6, a lower saddle 7 and a workbench 1. The upper saddle 6 is equipped with a lower gear plate 5, and the center of the upper saddle 6 is A piston 3 is sleeved, a support shaft 2 is sleeved in the piston 3, a worktable 1 is sleeved above the support shaft 2, and an upper toothed disc 4 is installed at a position where the worktable 1 is opposite to the lower toothed disc 5, and the sliding A nut seat 13 is installed on the saddle 7, and a screw nut 12 is arranged in the nut seat 13. The screw nut 12 is set on one end of a ball screw 11, and the other end of the ball screw 11 is driven by a motor 20. The working The bottom of the table 1 is connected with a transmission rod 14 covered with a compression spring 15, the transmission rod 14 is connected with the travel switch 18 through a switch collision rod 17, the bottom of the ...

Abstract

The invention relates to a numerical control novel indexing worktable at a horizontal machining center, which comprises an upper saddle, a lower saddle and a worktable. The upper saddle is equipped with a lower gear disk and a piston is sleeved in the center of the upper saddle, and a support shaft is sleeved in the piston. The worktable is sleeved on the upper part of the support shaft and provided with an upper gear disk. The lower saddle is equipped with a nut seat and a screw nut is provided in the nut seat. The screw nut is sleeved at one end of a ball screw which is driven by a motor. A transmitting rod sleeved with a compression spring is connected to the bottom of the worktable. The transmitting rod is connected with a travel switch by a switch collision rod, and a gear is connected to the bottom of the support shaft. The lower saddle is fixed with racks which are mesh with the gear. The worktable has simple structure, cost less, and has the advantage that the parts used are not easy to be worn. Besides, the worktable can maintain better precision and has longer service life.

Description

technical field [0001] The invention relates to a novel indexing workbench, in particular to a new numerically controlled indexing workbench for a horizontal machining center. Background technique [0002] The horizontal machining center is a high-tech product of mechanical and electrical integration, and it is also a machining center with high technological content in the CNC machine tool. The indexing table is the most critical functional component of the horizontal machining center. The manufacturing technology of this component is relatively difficult. Big. Usually, the indexing table of the horizontal machining center uses a servo motor to drive the worm-worm gear pair (or worm-worm gear pair + gear pair) to drive the table to rotate to realize the angular displacement of the table and achieve the purpose of indexing. The indexing accuracy, positioning accuracy and repeat positioning accuracy of the indexing table depend on the accuracy of the end toothed plate in the ...
