Abstract
The application discloses rotatory railing switch alarm device. This rotatory railing switch alarm device, including rotatory railing, cam, travel switch and installing support, the cam cover establish with on the rotatory railing, travel switch installs on the installing support, travel switch's contact supports on the cam. Rotatory railing is rotatory to be driven the cam is rotatory, will travel switch's contact is impressed, and the travel switch signal spreads, and the lathe is reported to the police. This novel rotatory railing switch alarm device simple structure, convenient assembling, simple to use, when rotatory railing was opened, equipment was reported to the police, unable operation.
Description
Technical field
The application is related to a kind of rotation guardrail switch alarm device, for the warning of machine safety guardrail switch.
Background technology
With the development of technology, the present lathe speed of service is more and more faster.When lathe runs, machine tool motion partial velocity
Quickly, therefore need security protection in lathe operation area, be that convenient adopt of work rotates guardrail more.In real work, rotation
Turn guardrail and need often to open and carry out equipment adjustment, staff has the possibility forgetting to close rotation guardrail unavoidably, easily leads
Cause collision or the generation of other accident.So this device is unreasonable, need to improve.
Utility model content
The purpose of this utility model is to provide a kind of rotation guardrail switch alarm device, with overcome of the prior art not
Foot.
For achieving the above object, the following technical scheme of this utility model offer:
The utility model discloses a kind of rotation guardrail switch alarm device, include rotating railing, cam, travel switch and
Mounting bracket, described cam sheathed with described rotation railing on, described travel switch is arranged in described mounting bracket, described row
The contact of Cheng Kaiguan is against on described cam.
Preferably, in above-mentioned rotation guardrail switch alarm device, described cam is provided with jackscrew.
Preferably, in above-mentioned rotation guardrail switch alarm device, the contact of described travel switch is roller type.
Preferably, in above-mentioned rotation guardrail switch alarm device: the contact rotating direction of described travel switch with convex
Wheel is tangent.
Preferably, in above-mentioned rotation guardrail switch alarm device, described mounting bracket has horizontal long lumbar hole.
Compared with prior art, the utility model has the advantage of:
1st, this rotation guardrail switch alarm device structure is simple, easy to assembly, does not affect cost；
2nd, this rotation guardrail switch alarm device using simply, when rotation railing is opened, it is impossible to operating, keep away by equipment alarm
Exempt to throw into question because rotating machine tool running when railing is opened by mistake.
Brief description
In order to be illustrated more clearly that the embodiment of the present application or technical scheme of the prior art, below will be to embodiment or existing
Have technology description in required use accompanying drawing be briefly described it should be apparent that, drawings in the following description be only this
Some embodiments described in application, for those of ordinary skill in the art, on the premise of not paying creative work,
Other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 show the schematic diagram rotating guardrail switch alarm device in this utility model specific embodiment.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Detailed description is it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole enforcement
Example.Based on the embodiment in this utility model, those of ordinary skill in the art institute on the premise of not making creative work
The every other embodiment obtaining, broadly falls into the scope of this utility model protection.
Shown in ginseng Fig. 1, rotation guardrail switch alarm device in this utility model embodiment, include rotating railing 01, convex
Wheel 02, travel switch 03 and mounting bracket 04, cam 02 center has on through hole 0201 the sheathed railing 01 with rotation, and stroke is opened
Close 03 to be arranged in mounting bracket 04, the contact 0301 of travel switch is against on cam 02.
Preferably, cam 02 is provided with jackscrew 0202, is used for fixing cam 02.
Preferably, the contact 001 of travel switch 03 is roller type.
Preferably, contact 0301 rotating direction of travel switch 03 is tangent with cam 02.
Preferably, mounting bracket 04 has horizontal long lumbar hole 0401.
During installation, first cam 02 is inserted on rotation railing 01 by centre bore 0201, travel switch 03 is passed through solid
Fixed rack 04 is fixing, then contact 0301 adjustment cam 02 height according to travel switch 03, and fixing by jackscrew 0202, then
The position of travel switch 03 is adjusted so that the contact 0301 of travel switch 03 by horizontal long lumbar hole 0401 on fixed support 04
It is against on cam 02.When rotation railing 01 is closed, the contact 0301 of travel switch 03 is against in the plane of cam 02, contact 0301
It is in not compressive state, no signal exports, lathe normally runs；When rotation railing 01 is opened, the contact 0301 of travel switch 03
It is against in the cambered surface of cam 02, contact 0301 is in compressive state, has signal output, lathe is reported to the police it is impossible to normal run.
This Novel rotary guardrail switch alarm device structure is simple, easy to assembly, using simple, when rotation railing is opened,
Equipment alarm is it is impossible to operate, it is to avoid throw into question because rotating machine tool running when railing is opened by mistake.
It should be noted that herein, such as first and second or the like relational terms are used merely to a reality
Body or operation are made a distinction with another entity or operation, and not necessarily require or imply these entities or deposit between operating
In any this actual relation or order.And, term " inclusion ", "comprising" or its any other variant are intended to
Comprising of nonexcludability, wants so that including a series of process of key elements, method, article or equipment and not only including those
Element, but also include other key elements being not expressly set out, or also include for this process, method, article or equipment
Intrinsic key element.In the absence of more restrictions, the key element that limited by sentence "including a ..." it is not excluded that
