Abstract

PURPOSE:To allow the vertical movement control of a vibrator while applying the static pressure by mounting the vibrator capable of adjusting the static pressure by a weight around a fulcrum provided on a vertically moving table on an arm provided vertically movably on the table. CONSTITUTION:After a weight 15 is adjusted, a vertically moving table 3 is lowered, and when a work is brought into contact with a tool 10 and the predetermined static pressure is applied, a vibrator arm 11 is separated from a vertically moving arm 6, and a microswitch is operated. A drive device 7 and the drive device of the vertically moving table 3 are driven by the processing program based on this signal to start processing, and when the vibrator arm 11 is lowered to the predetermined position and is brought into contact with the vertically moving arm 6, the predetermined processing is completed by the operation of the microswitch. In case of deep hole processing, after the processing is stopped, a vibrator 8 is lifted by the drive device 7 via the vertically moving arm 6 and the vibrator arm 11, and abrasion grains are automatically fed.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an ultrasonic processing machine for hard and brittle materials such as ceramics and glass, and particularly relates to a balance balance pressure type ultrasonic processing machine. Technology] Ultrasonic machining uses abrasive particles poured between the tool and the workpiece,
This is a method of machining by applying ultrasonic vibration to the tool while applying a predetermined pressure.In a balanced balance pressure type ultrasonic processing machine, a vibrator section with a tool is attached to one end of the balance centered on a fulcrum, and the other A suspended weight is attached to the end, and by adjusting the weight, the static pressure (
(processing pressure) is adjusted.

Conventional balance balance pressure type ultrasonic machining machines did not take into consideration automatic machining.

In addition, related to this type of ultrasonic processing machine are:
For example, Japanese Patent Application Laid-Open No. 57-102739 can be cited.

[Problem that the invention seeks to solve]

The above-mentioned conventional technology is inefficient because the operator manually moves the vibrator section up and down to improve the supply of abrasive grains by lifting the vibrator section equipped with the tool. It wasn't taken into consideration.

An object of the present invention is to provide an ultrasonic processing machine capable of automatic processing in a balance balance pressure type ultrasonic processing machine.

[Means for solving problems]

The above purpose is to provide a vertically movable table supported vertically on the front surface of the column, a vertically movable arm driven vertically by a drive device attached to the vertically movable table, and a vertically movable arm mounted on the front surface of the vertically movable table. a vibrator with a tool at its lower end, which is supported by a vibrator, a vibrator arm provided on the vibrator opposite to the upper part of the vertically movable arm, and a fulcrum fixed to the upper part of the vertically movable table; , a balance with the vibrator attached to one end and an adjustment weight attached to the other end;
This is achieved by providing a control device that detects contact or non-contact between the vibrator arm and the vertical movement arm and controls the vertical movement of the vibrator.

[Operation] When the vertical movement arm is moved downward by the drive device, the vibrator mounted on the vertical movement arm also moves downward via the vibrator arm, and when the tool comes into contact with the workpiece, the vibrator arm moves up and down. Machining starts at a distance from the movable arm and reaches a predetermined position v9.
When the vibrator arm comes into contact with the vertically moving arm, the machining is stopped, and the drive device lifts the vibrator via the vertically moving arm and the vibrator arm, and by repeating this vertical movement beforehand, new abrasive grain tools are always produced. and the workpiece, allowing automatic machining to be performed.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. In the figure, 1 is a column fixed on the bed 2;
Reference numeral 3 denotes a vertically movable table supported so as to be vertically movable along a guide rail 4 fixed to the front part of the column L.
Driven by L5. 6 is a vertically movable arm that is driven in the vertical direction by a drive device 7 attached to the side surface of the vertically movable table 3; 8 is a vibration arm that is supported so as to be vertically movable along a guide rail 9 fixed to the vertically movable table 3; Child, 1
0 is a tool attached to the vibrator 8, 11 is a vibrator arm provided on the upper part of the vertically movable arm 6, facing the vertically movable arm 6, and a microswitch recognition is incorporated inside. . 13 is a fulcrum fixed to the upper part of the vertically movable table 3; 14 is a balance centered on the fulcrum 13; a vibrator 8 is attached to one end of the balance; a suspended weight is attached to the other end; It is housed in a cavity within the column 1. Reference numeral 16 denotes a door provided on the rear side of the column 1. By opening this door and adjusting the weight, the static pressure applied to the tool 10 and the workpiece (not shown) can be adjusted. . 17, 18, and 19 are front and rear tables provided on the bed 2 for positioning the workpiece.

There are left and right tables and a rotating table. The water is abrasive-mixed water stored in the tanks in the left and right tables 18, pumped up by a bomber, and supplied between the workpiece and the tool 10 through the pipe n, and then through the discharge hole in the center of the rotary table 19. The water is circulated through the tanks of the left and right tables 18. Note that the above-mentioned vibrator 8 has two types, one for high output and one for small output.
The set of transducers 8 each have a fulcrum 13. Balance 14. weight 1
5. The drive device 7 is equipped with a vertically movable arm 6 and a vibrator arm 11, and is attached to a vertically movable table 3.

In the above-described configuration, first, the weight 15 is adjusted so that a predetermined static pressure is applied between the workpiece and the tool 10, and then the workpiece is mounted on the rotary table 19, and the vertically movable table 3 is moved downward. When the tool 10 comes into contact with the workpiece, the vibrator arm 11 separates from the vertical arm 6 and the microswitch 12 is activated. The position of the surface of the workpiece is received by the operation of this microswitch, and the oscillator 8. When processing is performed by driving the drive devices 5, 7 and the pump 4, and when the vibrator arm 11 descends to a predetermined position and contacts the vertically moving arm 6, the micro switch 12 is activated.
operates and completes the specified machining.

In hot machining situations such as deep hole machining where it is difficult to circulate the supply of abrasive grains to the tip of the tool IO, it is necessary to move the tool IO up and down so that new abrasive grains are always supplied. Therefore, when the vertical movement arm 6 is moved downward by the drive device 7,
Along with this, the vibrator 8 also moves downward, and when the tool 10 comes into contact with the workpiece, the vibrator arm 11 separates from the vertical arm 6, and the microswitch is activated to start machining.
When the vibrator arm 11 contacts the vertically movable arm 6 at a predetermined position, the microswitch 12 is activated to stop processing, and the vertically movable arm 6 and the vibrator arm 1 are moved by the drive bag 517.
1 and lift the vibrator 8 upward. By repeating the vertical movement of the vibrator 8 in this way, new abrasive grains can always be automatically supplied between the tool lO and the workpiece even during deep hole machining, and a predetermined deep hole machining can be performed. I can do it.

In addition, by providing two sets of vibrators 8, one for high output and one for small output, on the vertically movable table 3, after machining a large diameter hole with the vibrator 8 for high output, it is possible to drill a small hole without changing the setup.
