Abstract

PURPOSE:To prevent vibrations harmful to machining from being generated, by a method wherein a vibrator resonating with a vibration at a specified frequency of a frame of a surface grinder is provided at a part of the frame, and a damper oil is intermediately provided between the vibrator and the frame. CONSTITUTION:A pair of reinforcing plates 8 are fixed between a lower part of the rear face of a head 1 and both sides of an intermediate part of a supporting column 2. A vibration absorber 9 is placed on and fixed to the top of the column 2. A damper oil 12 is stored in a casing 11 fixed to the top of the column 2. A leaf spring 14 is fixed by clamping between a pair of clamping bodies 13 fixed to an upper surface of the casing 11, and the vibrator 15 is suspendedly fixed to a lower end part of the spring 14 in the condition of being immersed in the oil 12. When the column 2 and a grinding wheel spindle head 5 are integrally oscillated with a base part of the column 2 as a center, vibration of the column 2 at a specified frequency in forward and backward directions is damped by appropriately regulating the projecting length of the spring 14 and the viscosity and quantity of the oil 12, whereby the column 2 and the wheel spindle head 5 can be restrained from being oscillated.

Description

[Detailed description of the invention] Technique i”li+ Field This invention is a flat! rJl with built-in vibration damping device Jilt.
It opens into a cutting machine.

In the conventional ω1 grinding machine for flat grinding, the following motion during its operation is either thick or small, or if the vibration is too large, wavy irregularities will appear during grinding of the workpiece and the properties of the workpiece will deteriorate. .

Purpose of Defense 11'J is a plano-concave grinding machine that can eliminate the above-mentioned inconveniences by energizing vibrations that are harmful to everyone. 't1 foot 1-

From Example F, Example 1x] If you read it based on 1 river, 1ba/\soto, 2 is the support that is erected and fixed on the head 1,

The whetstone is the rotary whetstone installed at the tip C' of the head 5, and the motor for rotating the rotary whetstone 7Q (right 6). Shows the sweat cloth to be applied.

11111TL! A pair of reinforcing plates 8 are fixed at 18J between the back of the bed 1 and the 11111 side of the main part of the branch 2.
Sitting. 17. A vibration absorber 9 is mounted and fixed on one end of the support column 2.

The structure of the suction copying device 9 will now be explained based on FIG.
Kumper'il 12 is stored in 1ml. In this embodiment, as the tamper file 12, a commercially available 11-type tamper-resistant material (for example, 1" manufactured by Kiwamagari Co., Ltd. under the trade name Honnock SI' 38fnl for all flights) is used. A plate spring 14 is clamped and fixed between the pair of clamp f bodies 13 for L between the case 11 and the upper end of the plate spring 14, and a follower element 15 is attached to the upper end of the case 11.
It was immersed in a liquid 12 and hung in a suspended state.

Therefore, the tentative spring 14 is a bending motion of [j]], and this one time, swing! lll1-15 can vibrate at a specific frequency in the front-rear force direction at l/c. Therefore, the circumference of the column 2 centered around the 11th root of the column 1111 is the same frequency as the inverse of the force direction VC.
If the vibration is 1υ and the vibration is 9, it will resonate at the frequency of 15 thousand oscillators. For this reason, post 2 (1
) The following motion is damped by C by the tapper oil 12 and the vibrator 15, and the amplitude of the specific frequency of the support column 2 is reduced by a. Ma7j
, the natural frequency of the copying element 15 is determined by the length and strength of the blade 14, and the magnitude of the gap is determined by the viscosity of the Kumper oil 12.と”I (wo・11)
By completing the child Ik, you can set υ to 111().

Since it is possible to attenuate the longitudinal vibration g10 of the specific frequency of the branch office 2, it is possible to completely prevent the large trapping of the strut 2 and the sail Ei shaft head 5.
