Description
Technical field
The utility model relates to Ring Rolling Machine accessory field, especially a kind of ball-type Ring Rolling Machine mandrel device.
Background technology
The method that existing Ring Rolling Machine overlaps workpiece on mandrel is generally designed to mandrel upper and lower drawable, and oil cylinder is installed above support arm, moves up and down, and then add easily or take off ring in the drop-down moving mandrel of effect of oil cylinder.Although it is more convenient that this design is got the dress of ring, in structural design, increase the weight of the burden of support arm, make the loss aggravation of support arm, shorten the service life of Ring Rolling Machine.The mandrel lower end of drawable is in order to make mandrel separate with bearing, and the position of mandrel is unfixing, and like this, in the process of mandrel rotation, mandrel easily rocks swing, causes the inaccuracy of ring diameter.
Utility model content
The purpose of this utility model is to provide a kind of ball-type Ring Rolling Machine mandrel device.
Over-burden to support arm for mandrel the is Ring Rolling Machine structure of upper odd test that what the utility model solved is, easily causes the loss aggravation of support arm, shortens the Ring Rolling Machine problem in service life.
The technical scheme that the utility model solves its technical problem employing is: the utility model comprises support and mandrel; Described support comprises support arm and bearing, and one end of support arm is articulated with on bearing, and the other end is free end, and described mandrel upper end is connected with the free end of support arm, and lower end is connected with bearing; The free end that it is characterized in that described support arm is provided with manhole, cover and top on bearing, mandrel are installed in manhole from outside to inside successively, described bearing is placed on the outer ring of overlapping on mandrel, and the top of described bearing is provided with round nut, and round nut is also placed on the outer ring of overlapping on mandrel; On described top and mandrel, between cover, leave gap; The upper end of described top connects an engineering cylinder; The upper and lower end face of described manhole is respectively equipped with cover plate; Described engineering cylinder is arranged on the cover plate of upper surface of manhole, in described mandrel upper end is assigned and overlapped on mandrel; On described bearing, mandrel is installed and traps, in the lower end insertion mandrel of mandrel is trapped; Described mandrel is trapped bearing group is installed from outside to inside successively, main shaft and pull bar, and described pull bar connects the lower end with mandrel, and described main shaft below is provided with rotary sleeve.
The beneficial effects of the utility model are: the utility model is installing engineering cylinder on support arm, in the time that needs lift support arm, under the effect of engineering cylinder, on arm free end, lift, and then in conjunction with the oil cylinder on support, support arm are thoroughly lifted.The installation of engineering cylinder can facilitate lifting of support arm.Pull bar is installed in mandrel lower end and has been played good positioning action, also saved the length of mandrel, the periphery of pull bar puts rotary sleeve, the effect of the rotation of mandrel in process of having played convenience.This design, lower end that can fixed central spindle, can not make mandrel roll in rotary course, thereby improves the machining accuracy of workpiece.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises support and mandrel 10.Support comprises support arm 3 and bearing 4, and one end of support arm 3 is articulated with on bearing 4, and the other end is free end.Mandrel 10 upper ends are connected with the free end of support arm 3, and lower end is connected with bearing 4.
The free end of support arm 3 is provided with manhole, in manhole, install successively from outside to inside and on bearing 12, mandrel, overlap 11 and top 2, bearing 12 is placed on the outer ring of overlapping 11 on mandrel, and the top of bearing 12 is provided with round nut 13, and round nut 13 is also placed on the outer ring of overlapping 11 on mandrel.On top 2 and mandrel 10, between cover, leave gap.Sliding stroke is left with mandrel 10 upper ends in top 2.The upper end of top 2 connects an engineering cylinder 1.The upper and lower end face of manhole is respectively equipped with cover plate 3-1 and cover plate 3-2, and cover plate 3-1 and cover plate 3-2 utilize and be bolted on support arm 3.Engineering cylinder 1 is arranged on the cover plate 3-1 of upper surface of manhole.Mandrel 1 upper end is assigned on mandrel and is overlapped in 11.
Mandrel is installed on bearing 4 and traps 9, the lower end of mandrel 10 is inserted mandrel and is trapped in 9, and mandrel is trapped and 9 bearing group 7 is installed from outside to inside successively, main shaft 8 and pull bar 5.Pull bar 5 connects the lower end with mandrel 10.Main shaft 8 belows are provided with rotary sleeve 6.
Between pull bar 5 and mandrel 10, utilize inner sleeve 15 fixing, pull bar 5 lower ends pass rotary sleeve 6.
When work, under the effect of engineering cylinder 1, the free end of support arm 3 is lifted, and then, under the effect of the oil cylinder 14 between bearing 4 and support arm 3, support arm 3 is just picked up easily, and therefore engineering cylinder 1 has the effect of auxiliary cylinder.Pull bar 5 is arranged on mandrel 10 lower ends and has played good positioning action, ensure that mandrel can not rock, guarantee the precision of processing, the length of also having saved mandrel 10, the periphery of pull bar 5 puts rotary sleeve 6, the effect of the rotation of mandrel 6 in process of having played convenience.
