Abstract
The utility model relates to a machine tool assist device, belonging to a technology field, in particular to a central bracket of the machine tool, comprising a V-shaped pallet, a screw, a nut, a hand wheel, a superior bearing, an inferior bearing, a pallet base, and a bearing cap. The center of the V-shaped pallet is fixed at an end of the screw; the nut is sheathed on the screw; the hand wheel is rigidly connected with the nut which rotates with the hand wheel; the nut is of rotary connection with the pallet base through the superior bearing and the inferior bearing; the bearing cap is fixed on the bottom surface of the pallet base. When the bracket is used, the V-shaped pallet is fixed by operators not to rotate, at the same time the hand wheel is rotated to finish the up and down of the bracket. The utility model has the advantages of compact and small structure, low manufacture cost, both high efficiency and convenient operation, and avoidance of the problem of difficult clamping in the turnover processing of the bigger shaft parts.
Description
Technical field
The utility model relates to the machine tool auxiliary device technical field, especially a kind of lathe center rest.
Background technology
Lathe and cylindrical grinder usually need be processed some big slightly axial workpieces, and require the secondary clamping to reverse end for end to process, people of this big slightly axial workpiece operative employee can't implement secondary tune clamping, and general the employing has three kinds of methods to finish: 1, overhead traveling crane lifting; 2, the other special use lifting facility that is provided with of lathe; 3, many people manually finish.
Adopt overhead traveling crane lifting operative employee that the process of a wait is often arranged, influenced that operating efficiency and this overhead traveling crane facility neither all factory buildings can both possess; Other special-purpose lifting facility such as tripod, the door frame etc. of being provided with of lathe, such facility operations bothers, efficient is low, easily have the lifting accident, and facility has also taken the work-yard simultaneously; Many people manually finish dangerous equally especially, and efficient is low.
Summary of the invention
In order to overcome the low and unsafe deficiency of existing hanging method efficient, the utility model provides a kind of lathe center rest, and this lathe center rest is highly effective and safe not only, and easy and simple to handle.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of lathe center rest includes V-type pallet, screw rod, nut, handwheel, upper bearing (metal), lower bearing, bracket base, bearing cap; The center fixation of V-type pallet is at an end of screw rod, and nut sleeve is on screw rod, and handwheel is fixedly connected with nut, nut rotates with handwheel, and nut turns by upper bearing (metal) and lower bearing and is connected in bracket base, and bearing cap is fixed on the bottom surface of bracket base.As another form is to be provided with the commentaries on classics lining between described nut and upper bearing (metal) and lower bearing.Described upper bearing (metal) and lower bearing are for having the structure of energy bearing radial force and axial force respectively.It also can be the structure that described upper bearing (metal) and lower bearing all have energy bearing radial force and axial force simultaneously.
Furtherly, be provided with spring bearing with the machine tool guideway corresponding position on described bracket base, spring bearing is four; Or on described bracket base, be provided with the chute that coincide with machine tool guideway with the machine tool guideway corresponding position.
Again furtherly, on described bracket base, also be provided with and make the device of carriage corresponding to the lathe positioning and locking.
The beneficial effects of the utility model are, at the bottom of this lathe center rest compact conformation, small and exquisite, the manufacturing cost, and highly effective and safe not only, and also easy and simple to handle, solved the clamping difficult problem of big slightly axial workpiece tune processing.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a cutaway view of the present utility model.
Fig. 2 is that the A of Fig. 1 is to view.
Among the figure 1, V-type pallet 2, screw rod 3, nut 4, handwheel 5, upper bearing (metal) 6, lower bearing 7, bracket base 8, bearing cap 9, change lining 10, spring bearing
The specific embodiment
As Fig. 1 is structure cutaway view of the present utility model, and a kind of lathe center rest includes V-type pallet 1, screw rod 2, nut 3, handwheel 4, upper bearing (metal) 5, lower bearing 6, bracket base 7, bearing cap 8; The center fixation of V-type pallet 1 is at an end of screw rod 2, machine made reliable and stable for guaranteeing, cooperate and be welded at the centre of gyration machining hole of V-type pallet 1 and with an end of screw rod 2 and be fixedly connected, this mode that is fixedly connected is not limited to adopt this Type of Welding, also can adopt screw thread to fix or sell and fixedly wait other fixed form; Nut 3 is enclosed within on the screw rod 2, the thread forms that nut 3 and screw rod 2 match, and what the utility model adopted is rectangular thread, reason is that the bearing capacity of rectangular thread is stronger, can certainly adopt as other thread forms such as trapezoidal, triangles; Handwheel 4 is 3 fixedly connected with nut, nut 3 rotates with handwheel 4, nut 3 is by thrust bearing 5 and radial bearing 6 rotatable being connected on the bracket base 7, this form can be thrust bearing 5 and radial bearing 6 be directly installed on the outer ring of nut 3, handwheel 4 also is directly to be fixed on the flange of nut 3; For considering the manufacturability of part processing, what accompanying drawing 1 adopted is another kind of form, being provided with between described nut 3 and thrust bearing 5 and radial bearing 6 exactly changes lining 9, the flange of nut 3, handwheel 4 are fixed on the flange that changes lining 9, and upper bearing (metal) 5 and lower bearing 6 are installed in to be changeed on lining 9 outer rings.Because the lathe center rest must bear axial compressive force, described upper bearing (metal) 5 and lower bearing 6 are for having the structure of energy bearing radial force and axial force respectively, it also can be the structure that described upper bearing (metal) 5 and lower bearing 6 all have energy bearing radial force and axial force simultaneously, what accompanying drawing 1 adopted is that upper bearing (metal) 5 is single thrust bearing, and lower bearing 6 is a single-row radial ball bearing.
Bearing cap 8 is fixed on the bottom surface of bracket base 7, in order to lower bearing 6 is positioned.
Be provided with four spring bearings 10 with the machine tool guideway corresponding position on the accompanying drawing 1 on described bracket base 7, the lathe center rest with this structure can be used to have the lathe of horizontal guide rail, and does to roll and move.
Can be provided with the chute that coincide with machine tool guideway with the machine tool guideway corresponding position on described bracket base 7 in addition, the lathe center rest is done to slide and is moved.
Can also be provided with as required on described bracket base 7 and can make the device of carriage corresponding to the lathe positioning and locking, this locking device can be used the method for bolt in conjunction with pressing plate.
Bracket base 7 can be decided according to the concrete structure of lathe with the combining form of lathe in a word.
When using this carriage, on one side living V-type pallet 1 surely, operating personnel do not allow it rotate, Yi Bian rotate the lifting that handwheel 4 can be finished carriage.
