Specific embodiment
The invention will be further described with reference to the accompanying drawings and embodiments.
Embodiment
Referring to Fig.1, a kind of PCB drill spindle tool changing protective device, including protecting seat 6, guard pin 3, bottom plate 4,2 and of tool apron
Cutter 1；The protecting seat 6 is set to 4 lower part of bottom plate, and the guard pin 3 passes through protecting seat 6, and between protecting seat 6 and guard pin 3
Equipped with spring, 3 lower end of guard pin is equipped with adjustable nut 5, and the guard pin 3 is slidably connected with protecting seat 6, and by adjustable
Nut 5 realizes limit up and down；The tool apron 2 is set to 4 top of bottom plate, and is fixedly connected with bottom plate 4, and the cutter 1 is located at tool apron 2
On；The tool apron 2 is connected with high level, and the guard pin 3 is connected with low level, after the tool apron 2 is contacted with guard pin 3, generates electricity
Signal feeds back to the control system of PCB drilling machine.
In the present embodiment, the tool apron 2 is mature technology, and 2 upper end of tool apron is leaf spring formula structure, and medium position is equipped with positioning
The shaft shoulder, lower end are spring core structure, as shown in Figures 2 and 3.By the radial floating of upper end leaf spring carry out the guiding of cutter with
It clamps, cutter protection is completed by lower end spring-compressed.
In the present embodiment, the 2 middle part positioning shaft shoulder lower end surface of tool apron and 4 upper end face contact of bottom plate play the role of positioning；Institute
It states after 2 lower end of tool apron is nested in bottom plate 4, holding screw 7 is used to complete to fix.
In the present embodiment, 6 profile of protecting seat is cylinder, and 6 upper end of protecting seat is equipped with cylindrical end tangs, on boss
End is equipped with cylindricality countersunk head through-hole.
In the present embodiment, 6 upper surface of protecting seat and contacts baseplate, and achieved a fixed connection by screw.
In the present embodiment, the guard pin 3 is a stepped shaft structure, and the bottom surface (face A) of 3 upper end of guard pin is matched with spring
It closes, top surface (face B) and tool apron 2 cooperate, and 3 lower end outer surface of guard pin is slidably connected with protecting seat 6.
In the present embodiment, the adjustable nut is standard component, is able to achieve guard pin and limits and adjust up and down triggering stroke A.
In the present embodiment, triggering stroke A should always be less than the compressible amount B of tool apron.
The working principle of the present embodiment:
1) tool apron defencive function self-test.The damage of 2 lower end spring strut of tool apron cannot support when cannot even reset completely, if tool apron is multiple
Position amount is less than A, then 2 lower end surface of tool apron and 3 upper end face contact of guard pin, and protective device persistently issues warning instruction, prompts tool apron
Defencive function failure；If tool apron reset amount is greater than A and is less than B, the practical stroke that triggers is less than A, default according to control system at this time
The allowable error range of triggering stroke A is determined, if carrying out exchanging knives process protection 2) within the scope of allowable error, if
Beyond error range, protective device issues alarm command.
2) exchanging knives process is protected: after main shaft receives the tool changing instruction of PCB control system of rig, band cutter 1 is aligned downwards,
After cutter 1 contacts tool apron 2, the upper end of tool apron 2 is softened, and realizes cutter guiding and clamping function by the radial floating of leaf spring,
The lower end spring of tool apron 2 realizes cutter support by compression；When the volume under pressure of tool apron 2 is equal to triggering stroke A, the touching of 2 lower end surface of tool apron
Touch the upper surface of guard pin 3, at this time protective device formed communication loop, feed back to control system residue can tool changing stroke (B-A),
If tool changing is completed in remaining tool changing stroke, completion is protected；If not completing tool changing in remaining tool changing stroke, tool changing stops and issues
Warning instruction.
