Description

A tooling for machining inclined journal

technical field

The utility model relates to the technical field of tools, in particular to a tool for processing inclined journals.

Background technique

As a special workpiece, the inclined journal is difficult to process due to the certain angle between the journal and the axis of the main shaft, and requires high precision. When machining in a CNC machining center, multiple sets of fixtures are required, and the positioning reference needs to be changed multiple times. and multiple stress relievers. Although the machining accuracy of parts can be guaranteed by numerical control machining, there are many procedures and low production efficiency in this method. At present, in most domestic machining enterprises, the number of CNC machining equipment is small, and there are many production tasks. How to use ordinary machine tools to replace their production without affecting the quality of parts and improve processing efficiency has become an urgent problem to be solved by technicians in this industry.

Utility model content

Based on the deficiencies of the prior art, the problem to be solved by the utility model is to provide an inclined journal processing tool, which is convenient and fast in clamping and high in production efficiency.

In order to solve the above technical problems, the utility model provides an inclined journal processing tool, including a connecting assembly, a chuck, a counterweight, an upper connecting plate and a lower connecting plate; the lower end of the upper connecting plate and the lower connecting plate The upper end is connected as a whole, and the angle formed by the surface of the upper connection plate and the surface of the lower connection plate makes the axis of the part to be processed have the same angle as the axis of the processing part; the upper end of the upper connection plate is provided with a connection assembly; A counterweight is provided at the lower end of the lower connecting plate; the clamp is fixedly connected to the lower connecting plate and the axis of the clamp is perpendicular to the lower connecting plate.

As a further improvement of the above technical solution: the connection between the lower end of the upper connecting plate and the upper end of the lower connecting plate is provided with a reinforcing rib plate to improve its reliability during operation.

During processing, one end of the part to be processed is fixedly connected with the fixture through the connecting assembly 1, and a counterweight 3 is added as required. Then hoist the lathe (grinder) as a whole. The right end of chuck 2 is clamped on the turntable claw 7 of the lathe (grinder). The tailstock apex 6 of the lathe abuts on the apex hole at the left end of the part to be machined. Through the utility model, the part to be processed can be tilted at a certain angle, so that the axis of the tilted journal to be processed is in the horizontal direction which is favorable for lathe (grinding machine) processing.

The technical principle of the utility model is to convert the included angle between the machined journal and the long axis of the part into the included angle of the tooling fixture, and the precision of the part is guaranteed by the precision of the fixture itself. Fast and convenient clamping, high production efficiency. The purpose of replacing the production task of the CNC machining center by the ordinary machine tool is realized.

The structure of the utility model can process inclined journals on ordinary lathes and grinders without the need for large-scale machining centers, simplify the process, reduce the requirements for production equipment, and have great applicability and popularization significance in the processing of such parts.

The parts processed by the utility model have been applied to a certain type of machine, and the effect is good.

The utility model will be described in detail below in conjunction with the accompanying drawings. As a part of this description, the principle of the utility model will be described through embodiments. Other aspects, features and advantages of the utility model will become clear at a glance through the detailed description.
