Embodiment Construction

[0013] The automatic indexing workbench for machine tools of the present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.

[0014] The present invention is an automatic indexing workbench, not a continuous operation workbench. Therefore, the present invention is the same as the traditional automatic indexing workbench. The number of divisions of the indexing table is limited, and the number of equal divisions is determined by the tooth plate used for positioning. The number of teeth usually has three types of end tooth discs: 1 degree 360 ​​equal divisions, 3 degrees 120 equal divisions and 5 degree 72 equal divisions. According to user requirements, machine tool manufacturers will choose one of them to configure on the machine tool.

[0015] See figure 1 , an automatic indexing workbench for machine tools, which is used to be fixedly installed on the machine tool, the machine tool includes a machine tool b...

Abstract

The invention relates to an automatic indexing worktable for a machine tool. During indexing, firstly, an oil cylinder body drives a lower tooth disc to descend until the lower tooth disc is totally deviated from an upper tooth disc and a positioning disc; a direct-current brushless motor drives a motor end cover (worktable) to rotate, and synchronously drives the upper tooth disc connected with a motor lower end cover to rotate for indexing; and when the indexing is in place, the rotation is stopped. The oil cylinder body drives the lower tooth disc to ascend until the lower tooth disc is totally engaged with the positioning tooth disc and the lower tooth disc; and the positioning is finished. At this time, the automatic indexing and positioning functions of the worktable are realized. The automatic indexing worktable for the machine tool adopts an outer rotor direct-current brushless motor direct driving mode, is directly connected with an outer rotor by bolts, is more compact in mechanical structure, fast in indexing, short in action time, high in transmission efficiency and more obvious in energy conservation and consumption reduction, and belongs to an energy saving product.

Description

technical field [0001] The invention relates to the technical field of machining centers, in particular to an automatic indexing workbench for machine tools. Background technique [0002] The automatic indexing table is the most critical functional part of the machining center, especially the horizontal machining center. The common automatic indexing table can be divided into three types of automatic indexing devices in terms of its transmission mode. : One is an automatic indexing device with motor+gear reduction, in which the gears are used for deceleration and torque increase. The second is an automatic indexing device with motor + worm gear pair, wherein the worm gear pair is also used for deceleration and torque increase. The third is the automatic indexing device of the motor+worm-plane roller cam pair. The first two types can achieve continuous indexing, the third type can only perform gap indexing, the rotation of the worktable is discontinuous during indexing, it ...
