Description
Technical field
The utility model relates to a kind of lathe protector, specifically refers to heavy vertical lathe beam lifting safety device.
Background technology
The lifting of heavy vertical lathe knife rest will lean on the lifting of crossbeam to realize, beam lifting relies on lifting support and lifting nut to realize, lifting mother is fixed in lifting support, and T-shaped leading screw, through lifting nut, makes crossbeam carry out elevating movement by lifting nut and being rotatably assorted of T-shaped leading screw.Because T-shaped leading screw is steel part, processing is inconvenient and cost is high, and for protecting T-shaped leading screw not to be worn, lifting nut wing plate adopts copper material to make.But because lifting nut is different from T-shaped leading screw material, the wearing and tearing of lifting nut after working long hours, can be caused, therefore the abrasion condition of lifting nut must be detected in use procedure on time.But in practical operation, after heavy vertical lathe has assembled, be difficult to detect copper nut abrasion condition, once wearing and tearing are excessive suddenly, cross beam water square can be caused upwards to tilt suddenly, landing even fast, very likely damage lifting support and T-shaped leading screw, even damage lathe, cause lathe to use, affect lathe service life, cause heavy losses.
summary of the invention
The object of this invention is to provide a kind of heavy vertical lathe beam lifting safety device, utilize this device the abrasion condition of lifting nut can be detected fast and can prevent from causing cross beam water unexpected inclination square upwards because lifting nut wearing and tearing are excessive.
For realizing above-mentioned technical purpose, the technical solution adopted in the utility model is: heavy vertical lathe beam lifting safety device, comprise the lifting support fixing with vertical car crossbeam, lifting nut is fixed in lifting support, T-shaped leading screw is through lifting nut, by T-shaped leading screw and being rotatably assorted of lifting nut, lifting support is moved up and down, it is characterized in that: bottom described lifting nut, be provided with a steel jam nut, fixed by some connecting bolts between jam nut and lifting nut, distance of reaction is left between the end face and the bottom surface of lifting nut of jam nut, T-shaped leading screw, through jam nut, can make jam nut with lifting nut synchronization lifting by T-shaped leading screw and being rotatably assorted of jam nut, the end face of jam nut and the bottom surface of lifting nut are provided with safety detection switch, when the distance between jam nut end face and lifting nut bottom surface is less than safe distance, safety detection switch output alarm signal.
Described distance of reaction is greater than 0.04mm.
Described safety detection switch comprises the induction coil being arranged on jam nut top and the warning inductor be arranged on bottom lifting nut.
For preventing loosening of connecting bolt between jam nut and lifting nut, described connecting bolt is head eye bolt, adopts wire binding between bolt and the head of bolt.
Adopt this heavy vertical lathe beam lifting safety device can Timeliness coverage lifting copper nut abrasion condition, owing to being provided with the jam nut engaged with T-shaped leading screw always, occur to tilt suddenly or the phenomenon of landing compared with crossbeam also can not be there is during galling at lifting nut in time.This device can make beam lifting action more safe and reliable, effectively improves machine tooling efficiency and service life.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figure 1, the crossbeam 1 of heavy vertical lathe knife rest is elevated and relies on lifting support 2 to realize moving up and down with coordinating of T-shaped leading screw 3.
As shown in Figure 2, the fixing lifting nut 4 in lifting support 2 inside, lifting nut 4 adopts copper material to make, and T-shaped leading screw 3 realizes moving up and down of lifting nut 4 and lifting support 2 through lifting nut 4 by coordinating rotation.
As shown in Figure 2, bottom lifting nut 4, be provided with a steel jam nut 5, fixed by some connecting bolts 6 between jam nut 5 and lifting nut 4.As shown in Figure 3, between the end face and the bottom surface of lifting nut 4 of jam nut 5, a distance of reaction α is left.
As shown in accompanying drawing 2 and accompanying drawing 4, T-shaped leading screw 3, through jam nut 5, can make jam nut 5 with lifting nut 4 synchronization lifting by T-shaped leading screw 3 with being rotatably assorted of jam nut 5.
As shown in Figure 2, the end face of jam nut and the bottom surface of lifting nut are provided with safety detection switch.In the present embodiment, preferred detection switch is distance-sensor, and model is Omron E2A-S08KS02-WP.As shown in Figure 2, this model inductor comprises the induction coil 7-1 being arranged on jam nut 5 top and the warning inductor 7-2 be arranged on bottom lifting nut.When the α value shown in accompanying drawing 4 is less than safety value, warning inductor 7-2 induction place is first got well and this signal is delivered to controller as alarm signal.Certainly the sense switch of other types be can also adopt except safety monitoring switch is lifted by institute in the present embodiment, as Hall element, switch, infrared distance measurement switch etc. touched.
The operation principle of this protector is: lifting nut 4 is after using wearing and tearing for a long time, lifting nut meeting integral sinking, the distance of reaction between the end face of jam nut 5 and the bottom surface of lifting nut 4 is caused to reduce, namely the α value shown in accompanying drawing 4 reduces, when α value is less than safe distance, warning inductor 7-2 induces signal and this signal is delivered to controller carries out alert process.Give foregoing description, the distance of reaction between the end face of jam nut 5 and the bottom surface of lifting nut 4 should be greater than induction safe distance.In the present embodiment, the distance of reaction of warning inductor 7-2 is less than 0.04mm, the distance of reaction between the end face of jam nut 5 and the bottom surface of lifting nut 4 should be controlled as being greater than 0.04mm when therefore arranging.
Jam nut 5 in this device also possesses following safeguard function, and when lifting nut 4 weares and teares comparatively serious, owing to there being jam nut 5 to engage with T-shaped leading screw 3 always, the crossbeam of heavy vertical lathe can not occur to tilt suddenly or landing.
For accurately controlling the distance of reaction between the end face of jam nut 5 and the bottom surface of lifting nut 4, as shown in Figure 4, between jam nut 5 and lifting nut 4, connecting bolt 6 adopts head eye bolt, adopts steel wire 8 to tie up between bolt and the head of bolt.Effectively can prevent connecting bolt 6 from loosening after adopting said structure, cause the change of the spacing of jam nut 5 and lifting nut 4.
