The utility model discloses can reduce the probability that the unit exception situation takes place to effectively protect the safety of lathe.
Description
Technical field
This utility model relates to a kind of machine tool safety protection device, especially a kind of spacing controlling organization of machine safety.
Background technology
Equipment safe spacing technology mainly has two ways at present, and a kind of mode is soft spacing, sets two limit points by mechanical origin position, one is upper limit one for lower limit, the most spacing for relative coordinate, so it can change along with the change of origin position, cause upper and lower spacing inefficacy.Another way is hardware limit, and the most spacing is to be performed by other original papers such as induction apparatuss, the most spacing can accurately safe spacing to equipment moving to certain point, but at present quite a few because of the caused equipment of the hardware failure safe example such as collide.
Summary of the invention
For the deficiencies in the prior art, this utility model provides a kind of spacing controlling organization of machine safety, by by equipment modification be hardware and software spacing with the use of, the probability that unit exception situation occurs can be reduced, thus effectively protect the safety of lathe.
nullThe technical solution of the utility model is: a kind of spacing controlling organization of machine safety，Seat is fixed including induction apparatus，Described induction apparatus fixes the load being provided with guide rail on seat and moving back and forth along guide rail under motor and screw rod transmission structure drive，Described induction apparatus is disposed with upper limit induction apparatus in fixing seat、Initial point induction apparatus and lower limit induction apparatus，Described upper limit induction apparatus、Initial point induction apparatus and lower limit induction apparatus are all connected with controller，Described upper limit induction apparatus is provided with soft limit point and constitutes non-contact inductive limit switch，Described lower limit induction apparatus is provided with down soft limit point and constitutes non-contact inductive limit switch，It is characterized in that: outside described upper limit induction apparatus, be additionally provided with hard limit induction device，Upper hard limit induction device is provided with hard limit point and constitutes mechanical contact sensing limit switch，Upper hard limit point is touching bar，Lower hard limit induction device it is additionally provided with outside described lower limit induction apparatus，The hardest limit induction device is provided with lower hard limit point and constitutes mechanical contact sensing limit switch，The hardest limit point is touching bar，Described hard limit induction device and lower hard limit induction device are all connected with controller.
Described upper limit induction apparatus, initial point induction apparatus and lower limit induction apparatus all use photoelectric sensor.
Described hard limit induction device and lower hard limit induction device all use displacement transducer.
The spacing of described hard limit point and upper soft limit point is 1mm.
Described lower hard limit point and under the spacing of soft limit point be 1mm.
The beneficial effects of the utility model are: this spacing controlling organization is spacing for the X, Y, Z axis of lathe, soft spacing in conjunction with controller, add the most spacing.The soft spacing of controller is that the origin position by machine sets, and the home namely offset relative to origin position, this position changes along with the change of origin position.Hard limit induction device is arranged on beyond soft stroke-limit scope, if soft spacing inefficacy or be interfered, beyond arrange parameter by time hard spacing will come into force, equipment emergent stopping, the most spacing is to be mechanically fixed position, the ectocines such as interference-free software faults is changed.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1-induction apparatus fixes seat, 2-upper limit induction apparatus, 3-initial point induction apparatus, 4-lower limit induction apparatus, the upper soft limit point of 5-, soft limit point under 6-, the upper hard limit point of 7-, hard limit point, 9-sensing chip under 8-.
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described further:
nullAs shown in Figure 1，A kind of spacing controlling organization of machine safety，Seat 1 is fixed including induction apparatus，Described induction apparatus fixes the load (not shown) being provided with guide rail on seat 1 and moving back and forth along guide rail under motor and screw rod transmission structure drive，Described induction apparatus is disposed with upper limit induction apparatus 2 in fixing seat 1、Initial point induction apparatus 3 and lower limit induction apparatus 4，Described upper limit induction apparatus 2、Initial point induction apparatus 3 and lower limit induction apparatus 4 are all connected with controller，Described upper limit induction apparatus 2 is provided with soft limit point 5 and constitutes non-contact inductive limit switch，Described lower limit induction apparatus 4 is provided with down soft limit point 6 and constitutes non-contact inductive limit switch，It is characterized in that: outside described upper limit induction apparatus 2, be additionally provided with hard limit induction device，Upper hard limit induction device is provided with hard limit point 7 and constitutes mechanical contact sensing limit switch，Upper hard limit point 7 is touching bar，Lower hard limit induction device it is additionally provided with outside described lower limit induction apparatus 4，The hardest limit induction device is provided with lower hard limit point 8 and constitutes mechanical contact sensing limit switch，The hardest limit point 8 is touching bar，Described hard limit induction device and lower hard limit induction device are all connected with controller.
In the present embodiment, described upper limit induction apparatus 2, initial point induction apparatus 3 and lower limit induction apparatus 4 all use photoelectric sensor；Described hard limit induction device and lower hard limit induction device all use displacement transducer；Described hard limit point 7 and the spacing of upper soft limit point 5, lower hard limit point 8 with under the spacing of soft limit point 6 identical, it is 1mm, described induction apparatus is fixed and is provided with sensing chip 9 in the middle part of seat 1, described load is further fitted with block or catch to coordinate with photoelectric sensor or displacement transducer to position.This utility model uses that soft or hard is spacing is used in combination, original soft spacing on the basis of install additional the most spacing, the most spacing position soft spacing outside scope, distance between soft limit point and hard limit point is 1mm, owing to hardware detection original paper should not frequently use, induction apparatus frequently use the service life that can reduce induction apparatus, soft spacing not do not lost efficacy in the case of the most spacing without using.
