Abstract
The invention relates to a double-column vertical lathe thimble structure. The structure comprises a left ram, a taper sleeve, a thimble and bolts, wherein the taper sleeve is fixed on the left ram of the vertical thimble through the bolts, and the thimble is installed in a taper hole of the taper sleeve. The structure is compact and reasonable, a device is installed on the left ram, during processing of a workpiece, the structure presses at the top of the workpiece downwards, large diameter runout of the workpiece is avoided, and the processing accuracy is improved; and the structure is mainly suitable for auxiliary processing of higher workpices by using a double-column vertical lathe.
Description
Technical field
The present invention relates to a kind of vertical lathe thimble structure, mainly be applicable to the processing of twin columns vertical lathe, belong to the machinery industry field.
Background technology
In machinery industry processing, it is larger that vertical lathe is mainly used in the processing work radius, the revolving body workpieces that working height is higher, but too high at the workpiece height of processing, and in the too high situation of workpiece rotating speed, it is large that the workpiece circular runout becomes, and causes Workpiece Machining Accuracy low.
Summary of the invention
The object of the invention is to original technical improvement, provide a kind of rational in infrastructure, simply, twin columns vertical lathe thimble structure cleverly, this thimble structure can reduce the circular runout of workpiece, and can guarantee machining accuracy in process.
According to technical scheme provided by the invention: a kind of twin columns vertical lathe thimble structure comprises left ram; Also comprise tapered sleeve, thimble and bolt; Described tapered sleeve is bolted on the left ram of vertical lathe, and thimble is installed in the tapered sleeve bellmouth.
Compact conformation of the present invention, reasonable; This device is installed on the left ram, and in workpiece process, this structure is pressed in the workpiece top downwards, can avoid workpiece that large circular runout occurs, and can improve machining accuracy; It mainly is applicable to the higher workpiece of twin columns vertical lathe secondary process working height.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in Figure 1, a kind of twin columns vertical lathe thimble structure comprises left ram 1, tapered sleeve 2, thimble 3 and bolt 4; Described tapered sleeve 2 is fixed on the left ram 1 of vertical lathe by bolt 4, and thimble 3 is installed in tapered sleeve 2 bellmouths.The tapering 1:10 of described tapered sleeve 2 bellmouths.
Described device is installed on the left ram, and in workpiece process, this structure is pressed in the workpiece top downwards, can avoid workpiece that large circular runout occurs, and can improve machining accuracy.It mainly is applicable to the higher workpiece of twin columns vertical lathe secondary process working height.
