Description

Technical Field

[0001] The invention belongs to the technical field of numerical control drilling machines, and in particular relates to an improved numerical control turbine worm indexing workbench drilling machine. Background Art

[0002] The indexing table drilling machine is a kind of equipment used for mechanical processing. It uses the indexing and positioning functions of the indexing table to automatically index according to the instructions of the control system to achieve boring, tapping and other tasks of the workpiece.

[0003] The CNC worm gear indexing workbench drilling machine with application number 201821277449.2 comprises a stepping motor, a precision worm gear reduction box, a main machine workbench, a U-shaped machine base, an adjustment seat for collecting workpieces to be processed, a lifting and lowering adjustment seat structure, an I-shaped frame, a crossbeam, fastening bolts and nuts, a drilling machine motor, a drilling machine reduction box, a return sleeve seat, and a hexagon socket bolt; the CNC worm gear indexing workbench drilling machine collects debris through a collection bucket, and the coverage of the debris collection is small, and the ejected debris may still affect the normal processing of the next workpiece;

[0004] According to the attached Figure 5 The existing CNC worm gear indexing workbench drilling machine shown in the figure comprises a base 1a, a longitudinal track 2a and a transverse track 5a are installed on the base 1a, a longitudinal linear motor 3a is installed on the longitudinal track 2a, a hole 4a is installed on the longitudinal linear motor 3a, a transverse linear motor 6a is installed on one side of the transverse track 5a, a linear motor 7a for driving the indexing chuck 8a to move is installed on the transverse linear motor 6a, and the CNC worm gear indexing workbench drilling machine moves the workpiece when in use. One end is clamped, and the workpiece is moved to the position where drilling is required by adjusting the longitudinal linear motor 3a, the transverse linear motor 6a, and the linear motor 7a to perform drilling processing. However, the debris generated by the drilling processing is easy to remain on the linear motor and the track. Long-term frequent processing and moving of the workpiece make the debris easily get stuck in the guide rail of the linear motor, thereby affecting normal processing. In addition, only one end of the workpiece is clamped. When processing longer workpieces such as cylindrical workpieces, a height difference is generated between the unfixed end and the fixed end of the workpiece, thereby affecting the processing accuracy. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides an improved CNC worm gear indexing worktable drilling machine, which can clean the guide rails and other components used for moving positions to avoid the situation where a lot of debris is stuck in the guide rails due to long-term and frequent processing, and can fix the two ends of longer workpieces to avoid the situation where the longer workpieces are deformed by gravity and thus affect the processing accuracy.
