Problems solved by technology

[0006] 2. The position of the mounting seat 3 and the air guide hole 301 is relatively far away from a tool 5, and the compressed air diffuses before approaching the tool 5, which cannot produce a good cooling and chip removal effect on the tool 5.
[0007] 3. The gap 202 between the brush groups 201 must be open on both sides to generate a detection path, and the vacuum degree is not good when pumping air

Embodiment Construction

[0020] Below in conjunction with accompanying drawing and embodiment the present invention is described in detail:

[0021] Such as image 3 , Figure 4 and Figure 5 As shown, the preferred embodiment of the pressure foot device 100 with cooling, dust removal and broken needle detection of the present invention is suitable for being installed around a tool 210 of a spindle unit 200 and cutting a substrate unit 300. The spindle unit 200 is arranged along an axis L. As shown in FIG. The pressure foot device 100 includes a body 10 sleeved on the bottom of the main shaft unit 200, a pressing unit 20 mounted on the bottom of the body 10, a positioning pin 30 for positioning the pressing unit 20 relative to the body 10, and a The detection unit 40 is used to detect whether the knife is broken.

[0022] The body 10 is hollow cylindrical and has a bottom surface 11 perpendicular to the axis L, an outer peripheral surface 12 extending upward from the outer peripheral edge of the b...

Abstract

The invention discloses a pressure pin device with functions of cooling, dust removal and broken pin detection, comprising a body, a pressing unit and a detecting unit, wherein the pressing unit is arranged at the bottom of the body. The body is provided with a bottom surface and two air guide channels approaching to the bottom surface, the pressing unit is provided with two guide holes and two air entraining channels which are communicated with the two guide holes and the air guide channels, and the detecting unit is provided with a signal emitter and a signal receiver which are arranged above the bottom surface of the body. By utilizing the air guide channels to guide into a high pressure air source, the purposes of cooling and dust removal are achieved; and the detecting unit is used for detecting whether a broken pin exists or not.

Description

technical field [0001] The invention relates to a processing machine, in particular to a pressure foot device of a substrate forming machine with cooling, dust removal and broken needle detection. Background technique [0002] In US5332341 and JP2000-735 patents, air jet holes or nozzles are provided on the pressure foot of the substrate processing machine to spray compressed air when the tool cuts the substrate to cool the tool and remove chips. This kind of substrate molding opportunity is equipped with a tool storage magazine on the side of the machine, and when the spindle completes a series of preset machining actions and returns to the tool storage magazine to change the tool, it will detect whether the tool is broken, which cannot be real-time during processing. If a broken knife is detected, there will be a loss that reduces the production capacity. [0003] In addition, in order to solve the above-mentioned lack, such as figure 1 and figure 2 As shown, there is ...
