Abstract
The utility model discloses a height-debugging support roller device, comprising a support roller, a bearing for mounting the support roller, wherein the bearing comprises an upper bearing, a lower bearing and a drive oil cylinder and the drive oil cylinder is mounted on the lower bearing to drive the upper bearing and adjust the height of the upper bearing; the support roller is mounted on the upper bearing. The drive oil cylinder is fixed in the lower bearing and a plunger of the drive oil cylinder is against the upper bearing and the oil pressure of the drive oil cylinder is adjusted by a machine tool main hydraulic system to make the plunger protrude and the upper bearing is pushed to make the roller move towards a face plate, furthermore part of the weight of the face plate and the workpiece is born to reduce the down-warping amount of the main axle. The oil pressure of the drive oil cylinder is generally relatively stable and after fixing the upper bearing, the support roller always supports the face plate, thus the down-warping fluctuation distance of the main axle is least. The height-debugging support roller device has features of simple structure, very convenient mounting and disassembling and is suitable for supporting various large horizontal machine tool face plates.
Description
Technical field
The utility model relates to a kind of adjustable height support roller device that supports large-size horizontal lathe floral disc that is mainly used in.
Background technology
A developing direction of modern horizontal machine tool is to maximize, vitals one floral disc of large-size horizontal lathe, and diameter has several meters, and weight can reach tens tons.Therefore main shaft has born the floral disc of fixedlying connected with it and the huge gravity downwarp of workpiece, thereby has influenced the concentricity of the folded workpiece of floral disc.
Existing support roller device comprises bearing, carrying roller assembly and leading screw.Bearing comprises two support plates and bearing plate, is flat " U " shape, can not realize up-down adjustment.Respectively opened a cylindrical hole on two support plates, the carrying roller assembly is installed in these two cylindrical holes by pin.Bearing plate is slidably mounted on the guide rail, and its lateral center has been opened a silk hole, thereby can regulate the bearing lateral attitude by the rotation of leading screw.The transverse ends of bearing plate has " U " shape hole, will prop up by " U " shape hole with screw after support position regulates
Seat is fixedly connected on the guide rail.The shortcoming of this support roller device is: one, adopt pin to connect between carrying roller assembly and the bearing, and not easy to assemble; Two, will become flexible inevitably after being used for fixing screw work a period of time of bearing, the carrying roller assembly can not support floral disc well.
The utility model content
The purpose of this utility model is to provide a kind of easy accessibility, and can accurately enduringly floral disc be supported on the adjustable height support roller device of a certain position.
This adjustable height examination support roller device that the utility model provides, comprise carrying roller, be used to install the bearing of carrying roller, described bearing comprises upper bracket, undersetting, driving oil cylinder, this driving oil cylinder is installed in and is used to drive upper bracket on the undersetting, regulate the height of upper bracket, described carrying roller is installed on the upper bracket.
Have the lead that moves up and down and lead for upper bracket on the described undersetting, by the guide effect of this lead, upper bracket is promptly realized relatively moving up and down along this lead, is easy to peace and tears open.
Be fixed with one in the undersetting of the present utility model and drive oil cylinder, the plunger of this driving oil cylinder heads on upper bracket, regulate the in-oil cylinder oil pressure of driving by the lathe main hydraulic system, make plunger stretch out, promoting upper bracket and roller moves to floral disc, and then the part weight of bearing floral disc and workpiece, the downwarp amount of main shaft is reduced.The oil pressure that drives oil cylinder is generally more stable, can guarantee enduringly that this carrying roller supports floral disc all the time after upper bracket is fixing, makes the downwarp fluctuation distance of main shaft minimum.The utility model is simple in structure, and installing/dismounting is all very convenient, is suitable for most large-size horizontal lathe floral discs that support.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of Fig. 1 left view.
The specific embodiment
From Fig. 1 to Fig. 4 as can be seen, this adjustable height examination of the utility model support roller device, comprise carrying roller 1, upper bracket 2, drive oil cylinder 3 and undersetting 4, have U-lag 21 on upper bracket 2 tops, bottom center has counter sink 22, the two ends, bottom have pilot hole 23, lead 41 has been welded at the top of undersetting 4, carrying roller 1 is installed on the U-lag 21 of upper bracket 2, upper bracket 2 is connected with the guider that undersetting 4 is formed by pilot hole 23 and lead 41, drives the inside that oil cylinder 3 is installed in undersetting 4, and its plunger heads on counter sink 22, on oil cylinder 3 sides interface 31 arranged driving, can be connected with the main hydraulic system of lathe.
When the utility model uses, floral disc is placed on the top of carrying roller 1, be driving oil cylinder 3 fuel feeding by interface 31, under the guide effect of lead 41, making the plunger that drives oil cylinder 3 head on upper bracket 2 moves up, height of support is realized adjusting, thereby be implemented in the change of the downwarp distance of main shaft on the floral disc, improve the concentricity of workpiece.
Claims (2)
