Abstract
The utility model relates to the field of mechanical manufacture, in particular to a stud claming device in lathe machining. The stud clamping device disclosed by the utility model comprises a lathe spindle and an apex, wherein an axial locating element is arranged in a taper hole of the lathe spindle, a workpiece is fixed between the axial locating element and the apex, a square clamp is arranged on a position where the workpiece is 1/3 length away from the axial locating element, and a lathe chuck is fixed on the square clamp. By adopting the technical means, so that the manpower and material resources are greatly saved, the cost is saved, the production efficiency is improved, the daily turning yield can be up to 200 workpieces, and the material utilization ratio is improved to 78.59% from original 50.48%.
Description
Technical field
The utility model relates to mechanical manufacturing field, is specifically related to the double-screw bolt clamping device in a kind of machine tooling.
Background technology
Jig is to be used for determining the tram of workpiece on lathe and the device of reliable grip.In machining, use anchor clamps can guarantee machining accuracy, the stabilized product quality of workpiece; Reduce non-cutting time, boost productivity greatly; Solve the practical problem of more difficult clamping in the machine tooling; Enlarge the scope of application of lathe; Reduce operator's labour intensity etc.Traditional bolted fixture more complicated, waste material, stock utilization is very low, and loses time again, and operation is various, and efficient is very low.Therefore design a kind of can saving time and the double-screw bolt clamping device of material, stock utilization and efficient all can improve greatly, for the improvement conventional brace, and implement the theme of creating conservation-minded society under the new situation very positive role is all arranged.
On the C618 lathe processing in, if with Φ 32mm round steel as blank, by Φ 32mm turning to Φ 28.28mm, use machining screw behind 4 planes of milling machine milling again, workpiece length overall 300mm, the long 190mm of the screw thread of M20, stock utilization only is 50.48%, and the workpiece waste is bigger; And add and want 4 planes of milling man-hour, must drill centers as the location benchmark; Turning adds man-hour according to routine chuck clamping, and each all will carry out centering workpiece; This processing scheme, efficient are too low, and the cost height.
Summary of the invention
The purpose of this utility model provides and a kind ofly can improve stock utilization greatly and processing is simple, save the double-screw bolt clamping device of operation.
To achieve the above object of the invention, the utility model double-screw bolt clamping device comprises lathe spindle and top, be provided with the axial location element in the taper hole of described lathe spindle, described axial location element and top between fixation workpiece, on the position of setting element 1/3 length, be provided with square anchor clamps in described workpiece distance axis, on described square anchor clamps, be fixed with lathe chuck.
Owing to adopted above-mentioned technological means, the utility model has been saved manpower and material resources greatly, has not only saved cost but also improved production efficiency, and the turning daily output can reach 200, and stock utilization can bring up to 78.59% from original 50.48%.
Description of drawings
Fig. 1 is the structural representation of the utility model double-screw bolt clamping device.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model comprises lathe spindle 1 and top 6, be provided with axial location element 2 in the taper hole of lathe spindle 1, fixation workpiece 5 between axial location element 2 and top 6, on the position of setting element 1/2nd three length, be provided with square anchor clamps 4 in workpiece 5 distance axis, on square anchor clamps 4, be fixed with lathe chuck 3.
With two essentially identical square bars of shape, material 45 steel also carry out modifier treatment, are made into axial location element 2 and square anchor clamps 4 respectively.The slitting an of 5mm of milling on the interior cubic angle of axial location element 2 wherein is used for locating clip clamping of workpieces 5 centerings, and square anchor clamps 4 do not mill open-minded, are used for determining the axial location of workpiece 5.
