Background technology
Milling machine is the lathe with milling cutter, workpiece being carried out to Milling Process, usual milling cutter rotary motion is main motion, the movement of workpiece or milling cutter is feed motion, be commonly used to process metal, outside milling machine decapacitation milling plane, groove, the gear teeth, screw thread and splined shaft, can also process the profile of more complicated, efficiency comparatively planer is high, is used widely in machine-building and repairing department.In use procedure, there is all potential safety hazards in milling cutter high-speed motion, such as: milling cutter fracture splashing, processing chip splash, injure human body; Clothes, gloves, jewellery, hair etc. are involved in; Or human body directly touches milling cutter etc., all easy staff to be damaged.
In prior art, milling machine is considering the security of device gradually, protective cover is increased to reach the effect of protection in the periphery of boring milling cutter, but these protectors existing not only complex structure, installation and removal are inconvenient, simultaneously because operating procedure is complicated, a few thing personnel do not follow safety operation specification, easily cause security incident.
Summary of the invention
In order to solve the problem; the invention discloses a kind of milling machine safety device; solve miller protective cover complex structure in prior art, loaded down with trivial details, that security is not high problem is installed; provide a kind of milling machine safety device with position sensor and controller; position sensor feedback signal is to controller; when protective cover does not arrive home, controller automatically controls milling machine motor and decommissions, and equipment safety is high.
The present invention is achieved by the following technical solutions:
A kind of milling machine safety device; comprise main spindle box; main spindle box side is provided with motor; below main spindle box, Drilling and milling head is installed; described main spindle box side is provided with rotating shaft holder; described rotating shaft holder is provided with rotating shaft; fixed bar passes the axle center of described rotating shaft and is fixed in axle center by locking nut; fixing fitting on protective cover is bolted to described fixed bar lower end by some; be provided with position sensor above described fixed bar, described position sensor and described motor are all connected with the controller being arranged on described main spindle box inside.
Preferably, described fixing fitting and described protective cover are formed in one.
Preferably, described protective cover is arranged on the periphery of described Drilling and milling head.
Compared with prior art, the invention has the beneficial effects as follows:
Novel structure of the present invention, protective cover is by fixing fitting and be bolted on fixed bar, and fixed bar passes rotating shaft axle center and is fixed in axle center, and assembly and disassembly are convenient; The milling cutter of high-speed motion and peripheral region not affecting under the prerequisite that milling machine normally works, can be isolated, eliminating potential safety hazard, strengthen labour protection by the present invention; When changing milling cutter, only need rotate fixed bar can remove protective cover, simple to operation; Fixed bar is provided with position sensor; the position signalling of fixed bar is passed to controller by position sensor, and controller whether at home, if at home, controls motor rotation according to signal determining protective cover; otherwise milling machine motor then cannot run, equipment safety coefficient is very high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In Fig. 1: 1, main spindle box; 2, Drilling and milling head; 3, motor; 4, controller; 5, protective cover; 6, fixing fitting; 7, bolt; 8, fixed bar; 9, rotating shaft holder; 10, rotating shaft; 11, axle center; 12, locking nut; 13, position sensor.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described:
A kind of milling machine safety device, comprise main spindle box 1, main spindle box 1 side is provided with motor 3, Drilling and milling head 2 is installed below main spindle box 1, described main spindle box 1 side is provided with rotating shaft holder 9, described rotating shaft holder 9 is provided with rotating shaft 10, fixed bar 8 passes the axle center 11 of described rotating shaft 10 and is fixed in axle center 11 by locking nut 12, fixing fitting 6 on protective cover 5 is fixed on described fixed bar 8 lower end by some bolts 7, position sensor 13 is provided with above described fixed bar 8, described position sensor 13 and described motor 3 are all connected with the controller 4 being arranged on described main spindle box 1 inside.
Described fixing fitting 6 is formed in one with described protective cover 5.
Described protective cover 5 is arranged on the periphery of described Drilling and milling head 2.
As shown in Figure 1, a kind of milling machine safety device, comprise main spindle box 1, main spindle box 1 side is provided with motor 3, Drilling and milling head 2 is installed below main spindle box 1, main spindle box 1 side is provided with rotating shaft holder 9, rotating shaft holder 9 is provided with rotating shaft 10, fixed bar 8 passes the axle center 11 of rotating shaft 10 and is fixed in axle center 11 by locking nut 12, fixing fitting 6 on protective cover 5 is fixed on fixed bar 8 lower end by two bolts 7, position sensor 13 is provided with above fixed bar 8, position sensor 13 and motor 3 are all connected with the controller 4 being arranged on main spindle box 1 inside.
Fixing fitting 6 and protective cover 5 are formed in one, and fixing fitting 6 is arranged on the side of protective cover 5, and both all adopt transparent impact-resistant material to make, and protective cover is arranged on the periphery of Drilling and milling head 2.
During installation, by bolt, rotating shaft holder 9 is fixed on the side of milling machine, fixed bar 8 is passed the axle center 11 of rotating shaft 10 and is locked by locking nut 12, the fixing fitting 6 on protective cover 5 is fixed on the lower end of fixed bar 8 with two bolts 7.
