Description

Combined direct drive indexing plate structure

The invention relates to the technical field of the machine tool assembly, in particular to a DD motor as a direct driving force, and a combined direct drive indexing disc structure for two-dimensional angle adjustment and positioning.

The indexing plate is an indispensable kit in the automation machinery, such as precision machining, assembly, production, etc.; the indexing plate can be used to generate the indexing and positioning functions, and the indexing plate can accurately control the rotation of the table, according to the processing The required cutting angle controls the displacement of the table at a relative angle to achieve precise positioning.

Conventional indexing discs are mainly made up of mechanical worm and worm gears. When the gears are rubbed, the friction of the gears will cause wear and then form backlash; therefore, frequent maintenance and shutdown procedures and related calibration procedures are required. Moreover, the mechanical indexing discs are mostly adjusted manually, which cannot meet the requirements of machine automation. To this end, people who have the heart have proposed the teaching of a motor-driven worm and worm gear, but instead derived other defects.

For example, when the motor drives the worm gear, it is necessary to use the deceleration device as a relay. In addition to the increase in volume and complexity of the structure, the axial length (volume) extending along the operating axis of the motor drive shaft must include the motor body, the reduction gear, and the worm. The length of the worm wheel is such that it lacks the surface of the processing machine and the surrounding space.

Furthermore, the conventional indexing plate can only provide one-dimensional (vertical or horizontal) axial angle adjustment. If it is to be changed from vertical axis to horizontal axis adjustment, the workpiece can only be removed from the indexing plate, and then Positioning through another axial indexing plate is not only cumbersome and inconvenient.

Therefore, how to replace the indexing disc of the mechanical transmission, and to accurately achieve the positioning, and shorten the axial length (volume) and other requirements, has become an urgent goal of the industry.

In view of the above problems and deficiencies of the prior art, the main object of the present invention is to provide a combined direct drive indexing disc structure, which is provided as an indexing disc by an electric drive method, and solves the conventional art. In addition to the loss of wear, large axial volume, etc., it can overcome the shortcomings of conventional techniques that can only provide one-dimensional angle adjustment.

According to the above object of the present invention, a combined direct drive indexing disc structure is proposed, which comprises a Y-axis indexing mechanism, an X-axis indexing mechanism and a connecting plate. The Y-axis indexing mechanism has a Y-axis connecting seat at least at the front end, and transmits a vertical axial rotation displacement amount through the Y-axis connecting base. The connecting plate member has first and second end faces, and is connected to the Y-axis connecting seat through the second end surface. The X-axis indexing mechanism is horizontally locked on the first end surface of the connecting plate member, and the top end has at least one X-axis connecting seat for outputting a horizontal axial rotation displacement amount, and can be provided as a table setting or a workpiece clamp. hold. By the composition of the above components, the two-dimensional angle adjustment and positioning of the workpiece can be provided under the premise that the workpiece is not disassembled, in order to meet the requirements Positioning requirements in the process.
