[0001] The utility model relates to the technical field of lathe processing equipment, in particular to a device for quickly processing inner and outer chamfers of sleeve-type workpieces on a lathe. Background Art

[0002] Aluminum alloy sleeve workpieces (lock tubes) are the main parts widely used in various types of industrial machinery and equipment and other fields of slings. The demand is large, and the process and processing efficiency are required to be high during mass production. At present, when ordinary lathes are used to process aluminum alloy sleeve workpieces, each sleeve workpiece is processed. The processing technology requires cutting, three-jaw chuck clamping rough material, flat end face, turning inner and outer circles, inner and outer chamfering, turning chamfering, and inspection and acceptance. Especially when processing inner and outer chamfering, it is necessary to change tools many times, rotate the tool holder, turn the workpiece around, and shake the tool holder and feed handle back and forth, etc., so that the processing steps of the inner and outer chamfering of sleeve workpieces are more, the process is cumbersome, not only takes a lot of time, but also the labor intensity of operators is high during mass production, which greatly reduces the overall processing and preparation efficiency of aluminum alloy sleeve workpieces. Therefore, it is necessary to further optimize the processing tooling of the inner and outer chamfering of aluminum alloy sleeve workpieces, so as to improve the overall production level of aluminum alloy sleeve workpieces.

[0009] The utility model has the following beneficial effects:

[0010] The utility model provides a device for quickly processing the inner and outer chamfers of sleeve-type workpieces on a lathe, which is mainly composed of a chamfering tool base, a mounting groove, an "X"-shaped chamfering tool, a workpiece guide sleeve, and inner and outer chamfering blades and the like. The chamfering tool base is fixedly rotatably arranged on the three-jaw chuck of the lathe, and the "X"-shaped chamfering tool bolt is fastened to the axial position of the chamfering tool base, so that when the center mounting frame drives the workpiece guide sleeve and the sleeve-type workpiece to move on the guide rail of the lathe, the inner and outer chamfering blades of the chamfering tool can accurately and quickly process the chamfers of preset sizes at the outer and inner edges of the sleeve-type workpiece, thereby greatly improving the processing convenience of the inner and outer chamfers of the workpiece, improving the overall processing and preparation efficiency of the sleeve-type workpiece, and solving the problem that in the current chamfering of aluminum alloy sleeve-type workpieces, due to the lack of special chamfering tooling, the tool is often frequently replaced, the tool holder is rotated multiple times, and the workpiece is transported complicatedly, which ultimately results in a variety of chamfering processing procedures and reduces the overall efficiency of lathe processing sleeve-type workpieces.

[0011] The chamfering tool in the utility model is an "X"-shaped chamfering tool, and the front and rear cross-arrangement of the outer chamfering blade and the inner chamfering blade effectively ensures the integrated forming of the outer chamfer and the inner chamfer during the feeding process of the aluminum alloy sleeve workpiece, thereby improving the overall convenience and efficiency of the inner and outer chamfering processing.

[0012] The provision of the workpiece guide sleeve in the utility model enables the aluminum alloy sleeve-type workpiece to be effectively axially positioned at the center mounting frame and plays a guiding role, thereby improving the overall accuracy of the internal and external chamfering turning of the workpiece.

[0013] The design of the "X"-shaped chamfering tool in the utility model enables the internal and external chamfers to be processed simultaneously. The ingenious positioning of the end face of the tool body makes the chamfering more consistent, and the coordinated centering of the guide sleeve and the center frame makes the concentricity of the chamfer and the inner hole better. The continuous rotation and turning of the tool eliminates the useless work of repeated clamping of the workpiece and tedious repeated movement of the tool holder, thereby improving the chamfering processing efficiency and achieving better chamfering consistency.
