Embodiment Construction

[0026] The existing ordinary lathe itself has the function of boring, and the present invention reforms the ordinary lathe to complete the boring of tapered deep holes. The remanufactured or added parts include boring bar 7, boring tool 10, double cone core rod 9, cylindrical core rod 28, threaded spline core rod 27 and so on. The three-jaw chuck 3 on the lathe spindle box 4 clamps the workpiece 2 with a tapered deep hole, and the center frame 33 presses the other end of the workpiece.

[0027] The oil feeder bracket 30 is fixed on a certain position of the guide rail of the bed 1 according to the length of the workpiece. The oil feeder bracket 30 is fixedly connected with the oil feeder seat 29, and one end of the rotary member 32 is mounted on the oil feeder seat 29 through a bearing. The other end is in contact with the end surface of the workpiece.

[0028] One end of the boring bar 7 is fixedly connected with the sliding plate 26, and the boring bar 7 is fed axially alon...

Abstract

The invention belongs to the technical field of a tapered hole processing device, and particularly relates to an engine lathe for tapered deep hole boring, which solves the problem that the conventional engine lathe cannot be suitable for the conditions that holes are too deep and a hole diameter is small. The engine lathe comprises a lathe body, a boring rod and a boring cutter, wherein holes are formed in the axial center and the radial direction of the boring rod, and the boring cutter is installed in the radial hole of the boring rod; a double-cone core rod is arranged in the axial hole of the boring rod; two cone bodies are arranged at the front end of the double-cone core rod, and the tapers of the two cones of the two cone bodies are equal; a floating gripper is also installed on the boring rod; and a tapered hole is formed in the boring cutter, and the axis direction of the tapered hole is parallel to that of the boring rod. The engine lathe has the beneficial effects that the demand on the engine lathe processing the tapered deep holes is realized, the defect that the boring rod is easy to deform during the tapered deep-hole processing is overcome, and the processing precision is increased.

Description

technical field [0001] The invention belongs to the technical field of devices for processing tapered holes, and in particular relates to a common lathe which can be used for boring tapered deep holes. Background technique [0002] Boring cylindrical holes has a mature technology, and boring conical shallow holes is also easy to implement. The difficulty of boring a deep tapered hole lies in the first, the overhang of the boring bar is large, the boring bar is easily deformed, and it is not easy to guarantee the processing quality. Second, in shallow hole machining, the radial feed of the boring tool is easy to realize, but when boring a deep tapered hole, it is difficult for the boring tool to feed radially in the same way as when boring a shallow hole. Third, it is difficult to directly use gun drilling, BTA drilling, DF drilling and other deep hole processing technologies to complete the boring of tapered deep holes. In the last century, human beings have overcome the t...
