Abstract
A drilling and tapping machine includes a power head assembly supported at a vertical orientation, a parallelogram arm structure including a head support and an arm base, and an arm positioning assembly coupled with the head support and the arm base support for guiding corresponding movements of the head support and the arm base support so as to ensure a vertical trajectory of the power head assembly. The machine further includes a counterweight configuration to vertically move the power head assembly via a lever. The machine further includes an operational control assembly to selectively shift the power head assembly between a drilling operation and tapping operation. Therefore, the machine is suitable to make a hole with a diameter of 0.5 to 3 mm.
Claims17
A drilling and tapping machine, comprising:
- a power head assembly supported at a vertical orientation;
- a head support, formed in a parallelogram, movably coupled at said power head assembly, wherein said head support comprises an upper head supporting arm, a lower head supporting arm and a supporting shaft, wherein said lower head supporting arm has the same length of said upper head supporting arm and is parallel to said upper head supporting arm, wherein said upper and lower head supporting arms are pivotally and spacedly coupled between said power head assembly and said supporting shaft to form a parallelogram;
- an arm base support, also formed in a parallelogram, movably coupled at said head support, wherein said supporting shaft of said head support is supported at a vertical orientation on said arm base support, wherein said arm base support comprises a first base supporting arm at a vertical orientation, a second base supporting arm which has the same length of said first base supporting arm and is parallel to said first base supporting arm, a first base supporting platform, and a second base supporting platform, wherein said supporting shaft is perpendicularly and upwardly extended on said first base supporting platform, wherein said first base supporting arm and said second base supporting arm are pivotally coupled between said first base supporting platform said and said second base supporting platform to form a parallelogram;
- and
- an arm positioning assembly coupled with said head support and said arm base support for guiding corresponding movements of said head support and said arm base support so as to ensure a vertical trajectory of said power head assembly, wherein said arm positioning assembly comprises a guiding member, having an arc-shaped guiding slot, coupled at said second base supporting platform, a guiding axle slidably engaged at said guiding slot, and a control arm extended from said guiding axle to said lower head supporting arm, wherein said second base supporting platform is stationary that when said guiding axle is slid along said guiding slot to actuate said control arm, said head support and said arm base support are correspondingly moved to ensure said power head assembly to be absolutely moved at a vertical orientation and to ensure said vertical trajectory of said power head assembly.
