Description

[Detailed Description of the Invention] Kokumyo has a guide bushing device (related to C) in a headstock movable type mouth 1 FII board.

In a headstock movable automatic lathe, there is generally a headstock that grips the rotating workpiece and moves it in the direction of the axial force, and a guidezossico device that is placed in front of the headstock and supports the workpiece.
It is composed of a tool rest equipped with a plurality of machining tools that move perpendicularly to the main shaft at the mouth of the guide Zoshiko, and a tool rest arranged opposite to the main shaft.

Conventionally, this type of automatic lathe used up one piece of processed material that was fed into the machine, and the machine stopped after finishing the process.

This machine must be stopped by a skilled worker.
l iJjJ, and the material remaining in the guide bush "1 end (equipment) is pulled out after the headstock, and the next new machining vJ material is moved to the shaft in the shuttle ζ guide bush."
Insert), after properly adjusting the diameter of the 131 diameter &, j5J ruru guide 1 shaft, and adjusting the 4-way out (...), the equipment was put into operation.This 1
-Material 'F31 set' 2) For the purpose of automating the work and saving labor ・Automatic 'rA l',) Feeding 4 stomachs were developed, but the adjustment due to 1 error' 1 work of the workpiece Extrusion is left to skilled workers as it has a significant impact on accuracy.

The machining accuracy of the workpiece is directly related to the gap between the guide push and the material.
For C/C, use materials with the same material tolerance (
Must be J.

However, abrasive materials with a small monthly interest rate are generally expensive.
Drawn materials with large tolerances can be cut manually at low cost.

In particular, when using materials with large tolerances (to improve the precision of the workpiece (a skilled worker pushes the guide according to the diameter of the material), the most intermediate work is to adjust the gap. There is C.

Previously, this type of glaze was devised to make the glaze work easier.
13. Connect the knot adjustment part with the tooth width C and hold it in the lift M that is easy for the operator to operate.・There is a method to make the removal work smoother, but the guide pusher 1-, which restores its elasticity, is connected to the spring horn through the screw 1.
1ゝ) Effect of fluid crossroads (・Materials and 1 person = neck opening,
After that, in order to set a certain gap between the material and the guide pushpiece, the problem of fine brush cutting management remained unsolved. However, all of the guide bush adjustment devices introduced in the Ir era do not automate the adjustment work, but instead solve many of the problems in a way that saves labor. It was hot.

The present invention solves the above conventional problems! I\\ku,
We provide a rotary guide bushing L equipment equipped with an automatic adjustment mechanism that measures the diameter of the workpiece and always maintains an adjusted guide gap for the workpiece. It is something.

Hereinafter, one embodiment of the present invention will be explained using drawings.

In Figure 1, a headstock 3 is installed in the upper part of the bed 2 of the automatic lathe 1 (see Figure 1).

The sliding part between the headstock 3 and the bed 2 uses a well-known flat sliding surface. 4 has a principal axis e. At the front part of the headstock 3 in the sliding direction (on the right side indicated by J3 in FIG. 1), a guide pusher 1 device 5 that supports the grindstone M is supported by a guide pusher support stand 6 in alignment with the center line of the spindle. I'm here. The main shaft 4 supported by the headstock 3 is connected with reflex 1 to shaft 7 inside the front of the main shaft 4, and the beef cattle ε3 is integrally connected with the main shaft 4 through the key 2ε3. ing.
