Abstract
The utility model discloses a beam lifting mechanism of a numerical control vertical lathe. The beam lifting mechanism comprises the lathe and a beam, and is characterized in that positioning abutted rods are installed on the two sides of a lathe stand column, each positioning abutted rod is provided with an adjusting block, and positioning devices are arranged at the lower ends of the two sides of the beam. Each positioning device comprises an oil hydraulic cylinder, a cylinder front cover, a cylinder back cover and a piston rod, wherein a wearing ring is arranged between the piston rod and the oil hydraulic cylinder, a lining is arranged between the piston rod and the cylinder front cover, a lining is arranged between the piston rod and the cylinder back cover, a screw rod is connected to the outer side end of the piston rod, and a microswitch and a collision block are arranged on the screw rod. Compared with the prior art, the beam lifting mechanism has the advantages that due to the facts that the lifting position of the beam is fixed and the error can be controlled within 0.01mm, after the beam is lifted, an operator only needs to add the corresponding gear difference value through a machining program, production can be started, auxiliary time is hardly added, and therefore production efficiency is improved.
Description
Technical field
The utility model relates to a kind of cross-rail-elevating mechanism of NC vertical lathe, belongs to mechanical field.
Background technology
Traditional vertical numerically controlled lathe cross-rail-elevating mechanism is manually controlled by operating personnel owing to its position location, can say without positioning accuracy, and its workpiece coordinate system just need to reset behind each moving beam, needs to consume certain production time.
The utility model content
The utility model is in order to solve above-mentioned deficiency, a kind of cross-rail-elevating mechanism of NC vertical lathe to be provided.
Above-mentioned purpose of the present utility model realizes by following technical scheme: a kind of cross-rail-elevating mechanism of NC vertical lathe, comprise lathe and crossbeam, it is characterized in that: described machine pillar both sides are equipped with the location rod, described location rod is provided with regulating block, lower end, described crossbeam both sides is provided with positioner, described positioner comprises oil hydraulic cylinder, cylinder front cover, cylinder bonnet and piston rod, be provided with wear ring between described piston rod and the oil hydraulic cylinder, described piston rod and cylinder front cover, be equipped with lining between the cylinder bonnet, described piston rod outboard end connecting screw rod, described screw rod is provided with microswitch and collision block.
The utility model advantage compared with prior art is: the utility model is owing to the position of beam lifting is fixed, error can be controlled in the 0.01mm, therefore, only needing operating personnel automatically to add corresponding gear difference by procedure behind the beam lifting can finish, begin to produce, increase hardly any non-cutting time, thereby improved production efficiency.
Description of drawings
Fig. 1 is the overall structure schematic diagram of the utility model embodiment.
Fig. 2 is the limitation enlarged drawing at A place among Fig. 1.
Fig. 3 is the structural representation of the utility model positioner.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
Such as Fig. 1, Fig. 2 and shown in Figure 3, a kind of cross-rail-elevating mechanism of NC vertical lathe, comprise lathe 1 and crossbeam 2, it is characterized in that: described lathe 1 column both sides are equipped with location rod 3, described location rod 3 is provided with regulating block 4, lower end, described crossbeam 2 both sides is provided with positioner 5, described positioner comprises oil hydraulic cylinder 51, cylinder front cover 52, cylinder bonnet 53 and piston rod 54, be provided with wear ring 55 between described piston rod 54 and the oil hydraulic cylinder 51, described piston rod 54 and cylinder front cover 52, be equipped with lining 56 between the cylinder bonnet 53, described piston rod 54 outboard end connecting screw rods 57, described screw rod 57 is provided with microswitch 58 and collision block 59.
Described regulating block 4 is used for adjusting location, both sides rod and is in parallel to guarantee positioning accuracy.When crossbeam 2 needs a mobile gear, the action of beam lifting motor is risen one section with crossbeam 2, so that both sides piston rod 54 separates with location rod 3, oil hydraulic cylinder 51 action live stopper rods are retracted, when crossbeam 2 moves near the precalculated position, both sides piston rod 54 stretches out, crossbeam 2 continues to move toward the precalculated position, and when piston rod 54 contacted the location with location rod 3, crossbeam 2 stopped mobile, oil hydraulic cylinder 51 actions clamp crossbeam 2, and crossbeam 2 shift actions are finished.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
