Abstract
The utility model relates to an ejector pin structure of a double-pillar vertical lathe. The ejector pin structure of the double-pillar vertical lathe comprises a left ram, a tapered sleeve, an ejector pin and a bolt, wherein the tapered sleeve is fixed on the left ram of the vertical lathe through the bolt, and the ejector pin is installed in a tapered hole of the tapered sleeve. The ejector pin structure of the double-pillar vertical lathe is compact and reasonable in structure. The ejector pin structure of the double-pillar vertical lathe is placed on the left ram, in the machining process of a workpiece, the ejector pin structure is pressed downwards to the top end of the workpiece, large radial jump of the workpiece is avoided, and the machining accuracy is improved. The ejector pin structure of the double-pillar vertical lathe is suitable for assisting in machining the workpiece with a large height in the double-pillar vertical lathe.
Description
Technical field
The utility model relates to a kind of vertical lathe thimble structure, mainly is applicable to the processing of twin columns vertical lathe, belongs 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 purpose of this utility model is 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.
The technical scheme that provides according to the utility model: 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.
The utility model compact conformation, 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 utility model.
The specific embodiment
The utility model is described in further detail 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.
