Two-segment type positioning device for tapping machine

Abstract

The invention discloses a two-type positioning device for a tapping machine. The device comprises a fixture mechanism and a clamping driving mechanism that are arranged on a base. The fixture mechanism includes two fixture units and two telescoping rod units that can be driven by the clamping driving mechanism to drive the fixture units to clamp nut parts, wherein each of the telescoping rod unitscomprises a pushing arm and a support push shaft rod that are telescopically pivoted between a fixture unit and the clamping driving mechanism, and a forced tightening member that is installed on thesupport push shaft rod and behind the pushing arm and a spring mounted between the pushing arm and the support push shaft rod. Through a structural design of the telescoping rod units, the fixture mechanism can be changed between a semi-clamping state and a forced tightening state, it is convenient for a skewed nut part to be righted under the semi-clamping state, wear between a righted nut partand a fixture is greatly reduced, and the quality of nut processing is improved.

Description

technical field [0001] The invention relates to a tapping machine, in particular to a component positioning device for the tapping machine. Background technique [0002] During the tapping process of nut parts, the nut parts to be tapped are usually transferred to the tapping machine through the blanking machine, and the nut parts are clamped by the tapping machine with a clamp mechanism, and then tapped with a tapping workpiece tooth. However, when the blanking machine blanks the nut parts to the tapping machine, the dropped nut parts usually do not fall on the tapping machine properly, so when the clamp mechanism clamps the nut parts, they are clamped The screw nut part may not have the same axis as the tapping workpiece, and the skewed phenomenon of the nut part will seriously affect the quality of the processed nut. [0003] Although some tapping machines are designed to straighten the skewed nut parts, in order to prevent the nut parts to be tapped from falling off, t...

However, when the blanking machine blanks the nut parts to the tapping machine, the dropped nut parts usually do not fall on the tapping machine properly, so when the clamp mechanism clamps the nut parts, they are clamped The nut part may not be in the same axis as the tapping workpiece, and the skewed phenomenon of the nut part will seriously affect the quality of the processed nut

[0003] Although some tapping machines are designed to straighten the skewed nut parts, in order to prevent the nut parts to be tapped from falling off, they are all fixed by the clamp mechanism after the nut parts are clamped and fixed by other machines. However, once the clamping mechanism clamps and fixes the nut part, the clamping force of the clamping mechanism is quite large, so if you want to push the nut part clamped by the clamping mechanism, you have to apply a large force Mechanical force, and it is easy to cause the nut parts to be worn by the fixture
