Abstract
The utility model discloses a workpiece clamping device, comprising a baseplate and bases. The workpiece clamping device is characterized in that three groups of bases are arranged on the same circumference on the periphery of the baseplate at equal intervals, the upper end of each base is provided with a built-in connecting rod, each connecting rod is provided with two pairs of upper support and lower support, and the supports are all provided with two pairs of left clamping head and right clamping head; and the bases and the connecting rods are connected by a circumferential base connecting shaft, and the connecting rods and the supports are connected through axial support connecting shafts. The workpiece clamping device solves the problems of labor waste in workpiece alignment and low efficiency of the traditional lathe clamping device, and is particularly suitable for clamping of a cylindrical workpiece for assembly and use in a numerical-control lathe machining process.
Description
Technical field
The utility model relates to the frock field of numerically controlled lathe, the device of clamping drum shape workpiece in a kind of specifically lathe in machining process.
Background technology
Present lathe clamping device generally adopts the lathe universal fixturing, for example three-jaw, chuck, and V-block structures etc. clamp round piece, carry out needed processing then and meet the requirements of shape and size.Its shortcoming is that in use the centering workpiece is required great effort, and efficient is low, and positioning accuracy also is subjected to the influence of workpiece location reference surface.
Summary of the invention
The utility model is for solving present lathe clamping device centering workpiece effort, and inefficient problem provides a kind of automatic location, clamps the device with inloading part fast.
The technical solution of the utility model is, a kind of Workpiece clamping device, comprise base plate, base, its special character is, three groups of bases of equidistant installation on the peripheral same circumference of base plate, built-in connecting rod is equipped with in the upper end of base, and upper and lower two pairs of bearings are housed on the connecting rod, two pairs of clamping heads about all being equipped with on the bearing; Between base and the connecting rod by enclose to the base connecting shaft connect, connect by axial bearing connecting shaft between connecting rod and the bearing.
During work, workpiece is put on the base plate, base radially moves inward under exogenetic process synchronously, connecting rod, bearing, the clamping head of base drive upper end are simultaneously close to workpiece, when clamping head contact workpiece outer surface, take place to float because of surface of the work uneven, rely on enclosing between base and the connecting rod to cooperate with axial bearing connecting shaft between the bearing to base connecting shaft and connecting rod, make each clamping head can an amount of work enclose to or axial wobble, reach with the tight of workpiece and contact.
Technique effect of the present utility model is that the employing technique scheme can realize that a kind of workpiece that can make remains on reliable and stable position, reaches the numerically controlled lathe clamping device of machining accuracy.
Description of drawings
Fig. 1 is a structural front view of the present utility model, and the accompanying drawing that makes an abstract.
Fig. 2 is a plan view of the present utility model.
In the drawings, 1 base plate, 2 bases, 3 base connecting shafts, 4 connecting rods, 5 bearings, 6 clamping heads, 7 workpiece, 8 bearing connecting shafts.
The specific embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is further specified.
As shown in the figure, three groups of bases 2 of equidistant installation on base plate 1 peripheral same circumference, built-in connecting rod 4 is equipped with in the upper end of base 2, and upper and lower two pairs of bearings 5 all are housed on each connecting rod 4, two pairs of clamping heads 6 about all being equipped with on every pair of bearing 5; Between base 2 and the connecting rod 4 by enclose to base connecting shaft 3 connect, between connecting rod 4 and the bearing 5 by 8 connections of axial bearing connecting shaft.
During work, drum shape workpiece 7 is put on the base plate 1, base 2 radially moves inward under exogenetic process synchronously, it is simultaneously close to workpiece 7 that base 2 drives connecting rod 4, bearing 5, the clamping head 6 of upper end, when clamping head 6 contact workpieces 7 outer surfaces, because of uneven generation the on workpiece 7 surfaces floated, rely on enclosing cooperating between base 2 and the connecting rod 4 to the axial bearing connecting shaft 8 between base connecting shaft 3 and connecting rod 4 and the bearing 5, make each clamping head 6 can an amount of work enclose to or axial wobble, reach with the tight of workpiece 7 and contact.
