Abstract
The invention relates to a beam lifting safety structure which is particularly applicable for a vertical lathe. The beam lifting safety structure comprises a case, a turbine, a lead screw shaft and a cover board. The lead screw shaft threads through a hole of the case; the turbine is installed on the lead screw shaft, with the upper end being locked by a second nut and a third nut and the lower end being supported and limited by a second thrust ball bearing; and the second thrust ball bearing is installed on the lead screw shaft inside the case through a second adjusting pad which is arranged on a lug boss of the hole. The beam lifting safety structure is characterized in that the beam lifting safety structure further comprises a pressing plate, a first bolt and a second bolt; the second bolt fastens the second nut and the third nut; and the pressing plate presses the second bolt and is fixed on the end face of the lead screw shaft through the first bolt. The beam lifting safety structure adopts the bolts for fastening and connecting; the original pre-fastening safety structure is changed; and instead, the nuts are adopted for pre-fastening, the bolts are adopted for fastening and the pressing plate is adopted for preventing looseness. In such a way, the beam lifting safety structure has double safety effects, the problem of axial looseness of a lead screw during the process of lifting a beam is effectively solved and the production safety is ensured.
Description
Technical field
The present invention relates to a kind of beam lifting safety structure, be specially adapted to vertical lathe.
Background technology
Vertical lathe crossbeam fast lifting structure can reach desired location fast, operating efficiency is higher, but at fast liter with when falling soon, can produce instantaneous impact, cause the elevating screw pre-pressing structure loosening, and then produce and to jump, causing error, lifting insurance institution is used for guaranteeing that the pretension of elevating screw is loosening.At present, widely used lifting pretension safety structure in the vertical lathe adopts the nut parallel connection to add the purpose that brake hoop reaches the pretension insurance.This structure is in long-term the use, and the lifting impulsive force through long-term can make nut loosening, produces axial jump, has potential safety hazard.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of beam lifting safety structure simple in structure, ingenious, rational is provided, this safety structure can effectively solve the loosening problem of existing vertical lathe crossbeam safety structure pretension.
According to technical scheme provided by the invention: a kind of beam lifting safety structure, comprise casing, turbine, screw axis, cover plate, described screw axis passes the hole of casing, sealing ring is equipped with in described screw axis and casing junction, described turbine is installed on the screw axis, its upper end is by the second nut and the 3rd nut check, the lower end is spacing by the supporting of the second thrust ball bearing, described the second thrust ball bearing is contained in the casing on the screw axis by the second adjusting pad, described the second adjusting pad places on the boss in hole, be characterised in that: it also comprises pressing plate, the first bolt and the second bolt, described the second bolted the second nut and the 3rd nut, described pressing plate is pressed on the second bolt, is bolted to the screw axis end face by first.
As a further improvement on the present invention, the first adjusting pad, the first thrust ball bearing and axle sleeve are housed on the described screw axis, described the first thrust ball bearing is installed in the described axle sleeve, described axle sleeve with the first nut screwing clamping on screw axis.
As a further improvement on the present invention, described cover plate is bolted on the casing with the 3rd.
The present invention compared with prior art, advantage is: the present invention adopts bolted to connect, change original pretension safety structure, by the nut pretension, bolted has the locking insurance of pressing plate again, so just has the double insurance effect, effectively solve the problem of beam lifting screw mandrel axial play, guaranteed production safety.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
Such as Fig. 1, described a kind of beam lifting safety structure comprises the first nut 1, axle sleeve 2, the first thrust ball bearing 3, the first adjusting pad 4, sealing ring 5, casing 6, the second adjusting pad 7, turbine 8, the second thrust ball bearing 9, screw axis 10, the second nut 11, the 3rd nut 12, pressing plate 13, the first bolt 14, the second bolt 15, cover plate 16 and the 3rd bolt 17.
The first adjusting pad 4, the first thrust ball bearing 3 and axle sleeve 2 are housed on the described screw axis 10, and described the first thrust ball bearing 3 is installed in the described axle sleeve 2, and described axle sleeve 2 usefulness the first nut 1 is tightened against on the screw axis 10.Cover plate 16 usefulness the 3rd bolt 17 is fixed on the casing 6.
The present invention adopts bolted to connect, and changes original pretension safety structure, and by the nut pretension, bolted has the locking insurance of pressing plate again, so just has the double insurance effect, effectively solves the problem of beam lifting screw mandrel axial play, has guaranteed production safety.
