In the utility model, one end of described hold-down bolt is inserted in support, and the other end is provided with setting nut after running through electromagnet.Turn setting nut to rotate hold-down bolt, elastic element compression or release, especially when discharging, outwards promote electromagnet, changes the gap of electromagnet and armature, realize the quick adjustment in magnet stopper gap.
The guiding of electromagnet of the present utility model and armature residual gap does not re-use the center bolt of existing product, but the armature using bearing pin to carry out in adhesive, dispose procedure leads.Preferably, guiding bearing pin is provided with between described electromagnet and armature.
For evading magnet stopper because of the brake clearance change that bolt looseness causes after continuous working, preferably, described magnet stopper is provided with the catch gear preventing described hold-down bolt from loosening.
Preferably, described catch gear is the stay be bolted on electromagnet, and stay is provided with the locking hole be fastened on setting nut.
Usual setting nut is hexagonal nut, and locking hole is the polygonal hole of 6*N, after being inserted in setting nut, keeps stay and setting nut to fix in circumference, simultaneously because the other end bolt of stay is fixed, implements to prevent nut loosening.
In another technical scheme, described catch gear is stay, and stay is provided with two locking holes, is fastened on respectively on different setting nuts.Namely the locking hole at stay two ends is fastened on different nut, prevents two setting nuts from loosening simultaneously.
The utility model improves installation and the gap adjustment mode of magnet stopper, improves while regulating efficiency and reduces labour intensity, ensure that magnet stopper installs the precision of location and the fluency of guiding, improves the performance of magnet stopper product.
The utility model compared with prior art, has following good effect:
1. the mounting means of magnet stopper is easier, laborsaving, can effectively reduce because magnet stopper deadweight causes bolt when installing and support tapped bore to fill inclined problem;
2. the gap adjustment mode of magnet stopper is more quick, laborsaving;
3. the anti-loosening effect of hold-down bolt is better;
4. the guiding of electromagnet and armature residual gap more accurately, effectively, and shearing force when evading braking is to the impact of hold-down bolt.
