Abstract
The utility model relates to a beam lifting screw abrasion alarming device, which mainly solves the problems that the manual observation of the clearance change is inconvenient, and the safety can notbe fully guaranteed. The device is characterized in that a proximity switch (4) is mounted on an insurance nut (1) under a lifting screw (2). The beam lifting screw abrasion alarming device had the advantages that the electron induction type automatic alarm can be realized, thereby achieving the purpose of electrical control, the observation is convenient, and the operation is safe.
Description
Technical field:
The utility model relates to a kind of lathe crossbeam lifting safeties, is specifically related to a kind of crossbeam lifting screw wearing and tearing warning device.
Background technology:
At present the method that generally adopts of vertical lathe crossbeam lifting safeties is that lock nut is installed in below the crossbeam lifting screw, and makes between lock nut and the crossbeam lifting screw and leave the gap.Change the abrasion condition of monitoring crossbeam lifting screw by the gap between artificial observation crossbeam lifting screw and the lock nut.During this method is used because crossbeam lifting screw is a very easily part of wearing and tearing, because of the gap of wearing and tearing between back itself and the lock nut can diminish gradually, behind no gap, crossbeam lifting screw then is in unsafe condition, the lifting screw of heavy wear is a serious potential safety hazard for whole lathe, must in time find and change.At present when changing crossbeam lifting screw mainly decides by the variation in artificial observation gap, this method is not only inconvenient, and security can not get abundant assurance, and along with huge day by day, the change of mounting means of lathe scale and the extensive use of Electrical Control Technology, rely on the change situation in eye-observation gap not only to become more and more difficult, and more and more fall behind.
The utility model content:
Technical problem to be solved in the utility model is that to overcome the variation in the artificial observation gap that exists in the background technology untimely, inconvenient and can not fully guarantee the problem of machine safety, and a kind of crossbeam lifting screw wearing and tearing warning device is provided, this device can have the characteristics convenient, handling safety of observing by near switch prompting in time and warning.
The invention for solving the technical problem can reach by following technical solution: this crossbeam lifting screw wearing and tearing warning device comprises lock nut, the lifting screw of external nut sleeve, the nut sleeve of gapped lock nut and built-in lifting screw was equipped with near switch on the lock nut below the lifting screw in the middle of screw was fixing.
The utility model is compared with the above-mentioned background technology can have following beneficial effect: this crossbeam lifting screw wearing and tearing warning device is by installing the abrasion condition that accurately detects crossbeam lifting screw near switch on the lock nut under the crossbeam lifting screw, and can realize that electric induction type reports to the police automatically, thereby reach the electrical control purpose, observation is convenient, handling safety.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Among the figure: 1-lock nut, 2-lifting screw, 3-screw, 4-be near switch, the 5-nut sleeve.
The specific embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
As shown in Figure 1, this crossbeam lifting screw wearing and tearing warning device comprises the lifting screw 2 of lock nut 1, external nut sleeve 5, the nut sleeve 5 of screw 3 fixing middle gapped lock nuts 1 and interior cover lifting screw 2, screw 3 prevents that lock nut 1 from following leading screw and rotating, and is equipped with near switch 4 on the lock nut 1 below lifting screw 2.
When assembling this device, determine that according to crossbeam lifting screw pitch it allows wear extent, rotate lock nut then and adjust the wear extent that equals to allow near the gap between switch contact and the crossbeam lifting screw, use screw 3 to pass lock nut 1 at last and be tightened against fully in the nut sleeve 5, change the gap width of having set and himself become flexible, fall to prevent that lock nut 1 from rotating with leading screw.
Adopt the new structure control of this automatic warning form convenient, fast, needn't manual observation, industrial accident is effectively avoided in the security that has obviously improved lathe, reduces economic loss.This novel alarming device can accurately be pointed out and report to the police, and therefore has vast market prospect.
Claims (1)
1, a kind of crossbeam lifting screw wearing and tearing warning device, comprise lock nut (1), the lifting screw (2) of external nut sleeve (5), the nut sleeve (5) of gapped lock nut (1) and built-in lifting screw (2) is characterized in that: be equipped with near switch (4) on the lock nut (1) below lifting screw (2) in the middle of screw (3) was fixing.
