Embodiment 1

[0037] like figure 1 As shown, the automatic edge-seeking system of this embodiment adopts a white steel needle gauge 1 with a precision of 0.001 mm, a diameter of 2 mm, and a length of 20 mm, and is loaded into the connecting sleeve 2 through interference fit; the connecting sleeve 2 adopts The 304 stainless steel precision tube with an outer diameter of 5.0 mm and an inner diameter of 1.99 mm is loaded into the return spring through an interference fit; the return spring 3 is a stainless steel spring with an inner diameter of 6.9 mm and a wire diameter of 1.0 mm, and a silicone tube is used as an elastic sheath 5 ; The first control board 12 integrates a 433MHz radio frequency transmitting module, a buzzer 8, an LED lamp bead 9, a triode amplifier circuit, a power input and processing circuit, and a signal input circuit, and is connected to the power module 15 through a spring 13; in this embodiment The power supply module 15 adopts three AG13 button batteries, and is covere...

Embodiment 2

[0042] like figure 2 As shown, the automatic edge finding system of this embodiment adopts a tungsten steel needle gauge 1 with a precision of 0.001 mm, a diameter of 4 mm, and a length of 30 mm, and is directly loaded into the return spring 3 through interference fit. The back cover 16 is processed by 201 stainless steel knurling rods. This example does not establish clamping rod, connecting sleeve, disc, and other methods are the same as embodiment 1.

Embodiment 3

[0044] like image 3 As shown, the automatic edge-seeking system of this embodiment adds a high-precision disc 21 on the basis of Embodiment 1, which is used for edge-finding of the mature surface of the flipped workpiece. Disc 21 utilizes a high-precision stainless steel code disc as the disc surface, and utilizes a precision copper chuck as its fixing seat. Fix the code wheel on the needle gauge and make sure it is concentric with the needle gauge.

Abstract

The invention provides an automatic edge finding system, which comprises an edge finding apparatus and a control apparatus. The edge finding apparatus is used for collecting edge finding signals and transmitting the signals to the control apparatus. The control apparatus is electrically and / or mechanically connected to a control system of an external mechanical device, and is used for controllingthe control system of the mechanical device by electrical and / or mechanical methods according to wireless edge finding signals sent by the edge finding apparatus, so as to achieve automatic edge finding. According to the automatic edge finding system, the detection precision is improved, the production difficulty of products is reduced, the dead zone range is reduced, as well as the edge and depthof a small hole, and an edge of a curved workpiece can be detected.

Description

technical field [0001] The invention relates to detection equipment technology, in particular to an automatic edge finding system. Background technique [0002] In the machining process, various drilling machines, lathes, milling machines, machining centers and other machines often need to use the edge finder to find the edge of the workpiece, and combine the grating ruler to establish coordinates, so as to accurately position the tool and the workpiece. At present, edge finders can be roughly divided into two types: mechanical type and photoelectric type. [0003] The mechanical edge finder uses the high-speed rotation of the machine to drive the edge finder to rotate, and judges the opposite edge according to the coincidence of the upper and lower sections of the edge finder. During use, the operator's skills and eyesight are required to be high, and the use is cumbersome. into a trend of elimination. [0004] The current photoelectric edge finder is easy to use, but it ...
