Description

Technical Field

[0001] This utility model belongs to the field of measuring tool technology, specifically an electronic photoelectric edge finder. Background Technology

[0002] As a testing tool, the edge finder has a long history in the field of CNC machining. With the continuous development of optoelectronic technology, the photoelectric edge finder has been widely used due to its high measurement accuracy. The photoelectric sensing edge finder utilizes the conductivity of the workpiece to form a current loop through the contact between the ball head and the workpiece surface, thereby emitting audible and visual alarm signals to indicate the coordinate position of the measured surface.

[0003] In the prior art, CN221911047U discloses a rapid tool setting device based on a photoelectric edge finder, including a housing, a DC generator, and a trigger circuit module. The housing is an insulated hollow cylinder, and the DC generator and trigger circuit module are installed from top to bottom inside the housing. The DC generator supplies power to the trigger circuit module. By changing the power supply method of the traditional photoelectric edge finder, a DC generator is set inside the edge finder. The machine tool spindle drives the motor shaft to rotate to supply power to the edge finder. At the same time, one end of the motor shaft serves as the clamping part between the edge finder and the machining center, and the other end is equipped with a probe. The diameter of the motor shaft is adapted to the clamping port diameter of a small CNC machining center, which solves the problem that the existing photoelectric edge finder is not suitable for small machining centers.

[0004] The aforementioned patent changes the power supply method of the traditional photoelectric edge finder by setting a DC generator inside the edge finder. The machine tool spindle drives the motor shaft to rotate to supply power to the edge finder. At the same time, one end of the motor shaft serves as the clamping part between the edge finder and the machining center, and the other end is equipped with a probe. The diameter of the motor shaft is adapted to the clamping port diameter of a small CNC machining center, which solves the problem that the existing photoelectric edge finder is not suitable for small machining centers. However, this electronic photoelectric edge finder still has some problems.

[0005] 1. When the above-mentioned electronic photoelectric edge finder contacts the metal workpiece being processed through the contact ball, the external circulation circuit is activated to detect and record the coordinates. This contact connection to the external circulation circuit may be affected by electromagnetic and other factors, resulting in errors and making the detection inaccurate.

[0006] 2. The probe ball of the above-mentioned electronic photoelectric edge finder is rotatably connected to the outer shell through the lower rotating shaft and bearing, and does not have a buffer function. This causes the probe ball and the lower rotating shaft to make rigid contact with the workpiece being detected, which can easily damage the probe ball and the lower rotating shaft and reduce its service life.

[0007] Therefore, an electronic photoelectric edge finder is proposed to address the above problems. Utility Model Content
