Abstract

PURPOSE:To detect the face to be worked in a short time by forming the structure of stopping the motor for lifting by utilizing the variation in the generated sounds of the motor for brushing caused with the end face of a rotating brush starting to touch with the face to be worked and regulating the face to be worked by the end face of the rotating brush which stops simultaneously. CONSTITUTION:A voice signal having passed through a band pass filter 32, i.e., the voice signal of the load time with the end face of a rotating brush having started its contact with the face to be worked is checked by being input to a malfunction preventing circuit 34 from an amplifier 33 and confirmed, and formed by a waveform shaping 35, thereafter, input to a solenoid switch 39 via a counter 36, sample holding part 37 and power amplifier 38. Thus a solenoid switch 39 is opened and the motor 20 for lifting is stopped. As a result, the rotary descent of a stopper is stopped, simultaneously the polishing device main body is also stopped with its descent together with the rotating brush, the end face of the rotating brush at this time coincides with the face to be worked and the detection of the position of the face to be worked is achieved.

(Prior technology) A deburring and polishing machine that uses a cup-shaped rotating brush is used to remove burrs from diamond-cast aluminum alloy parts and burrs that occur when cutting cast iron parts. However, in this type of deburring and polishing machine, it is necessary to perform polishing work by positioning the rotary swing so that it has an appropriate depth of cut with respect to the surface to be processed of the workpiece. For this purpose, the origin is set at the point where the rotating brush end surface is on the same plane as the workpiece surface, that is, when it starts to come into contact with the surface of the workpiece surface.
From this point, the rotating brush is advanced toward the surface to be processed by a predetermined depth of cut to perform polishing work.

(Problem to be Solved by the Invention) However, in general, the shape, size, etc. of a workpiece are not constant and vary in various ways, so the origin changes each time the workpiece changes. Therefore, the operator moves the rotating brush relative to the workpiece each time, finely adjusting the position of the end face of the rotating brush, and gauges whether the end face starts to come into contact with the workpiece, that is, whether the brush end face has reached the workpiece surface. Since the origin is determined by use or visual inspection, there are problems in that it requires skill and is extremely time-consuming and inefficient.

In Fig. 1, when the polishing device main body (5) is lowered by the fluid pressure cylinder (81) via the piston rod (9) and the bracket (7), the stopper receiving portion (
23) is abutted against the abutment head (24) of the stopper (16), and is ground Ff against the pressure of the fluid pressure cylinder (8).
f The apparatus main body (5) stops, and the end face of the rotating brush Ol is held at a position slightly above the processed surface of the workpiece (not shown). Note that the position of the stopper (16) is set in advance so that the rotating brush 01 will stop at the above-mentioned position (. Then, when the brush motor (15) is started,
The rotating brush ate is in no-load operation, and as shown in Figure 3, the sound generated at that time is converted into an audio signal from the microphone (3O), passes through the amplifier (31), and is sent to the bandpass filter (30).
2), but the audio signal is not output from the bandpass filter (32) because it is under no load. Next, the lifting motor (20) is driven to move the gears (2I), (
When the stopper (16) is rotated in the lowering direction by the stopper (19), the abutment head (24) of the stopper (16) contacts the fluid pressure cylinder (8) via the stopper receiver (23).
The radial bearing (26) and thrust bearing (27) of the combination of the abutment head (24) and the stopper (16) prevent the stopper (16) from rotating due to the pressure acting on the abutment head (16). Since the stopper (16) is rotatable relative to the stopper 24), the stopper (16) is lowered while rotating according to its pitch by screwing its inner thread (17) into the outer thread 18). At the same time, the polishing device main body (5), which is receiving pressure from the fluid pressure cylinder (8) via the stopper receiving portion (23), follows and descends together with the rotating brush α. When the end face of this rotating brush Ql reaches the workpiece surface and starts contacting it, the contact resistance causes the brush motor (1
5), the generated sound changes to that under load, and the microphone (30) receives this emitted sound and converts it into an audio signal, which is passed through an amplifier (31) to a bandpass filter (32). is input to. Since the frequency band of this generated sound is wider than that in the case of no load, the audio signal due to the excess is output from the band pass filter (32) and sent to the malfunction prevention circuit (34) by the amplifier (33). ), where a check is made to see if the audio signal recorded in 1TiI is due to a malfunction. Thereafter, the audio signal output from the bandpass filter (32) is shaped by a waveform shaping section (35), passes through a counter (36), a sample hold section (37), a power amplifier (38), and then passes through an electromagnetic switch (39). ) to the electromagnetic switch (3).
9) opens and the lifting motor (20) stops. As a result, the lowering of rotation of the 7th pa (16) is stopped, and at the same time, the polishing device main body (5) is also stopped lowering together with the rotating brush Ql.
At this time, the end face of the rotating brush α coincides with the workpiece surface,
Detection of the position of the workpiece surface is achieved. After that, when the workpiece is retracted from the end face of the rotating brush αl, the rotating brush OI
The contact between the end faces of the brush motor (15) is released, the brush motor (15) is operated under no load, the input signal to the electromagnetic switch (39) disappears, and the electromagnetic switch (39) returns to its normal state.

Subsequently, when the lifting motor (20) is driven downward again, the stopper (16) rotates and descends under no-load operation as described above, and the polishing device main body (5) and rotating brush α also descend. . And the gear (2) by the proximity switch (28)
When the amount of descent of the rotary brush OI reaches a predetermined depth of cut by measuring the number of tooth movements in step 1), a signal is sent from a control circuit (not shown) to the electromagnetic switch (39) of the lifting motor (20).
When this is opened, the lifting motor (20) stops, and the rotating brush α stops descending and is held at a predetermined cutting position. If the workpiece is moved toward the rotating brush OI in this state, brush polishing with a predetermined depth of cut is achieved. In addition, the height can be adjusted in the same way to compensate for the wear of the rotating brush Ql when a large number of workpieces of the same shape are polished continuously, and the height can be adjusted in the same way to compensate for the wear of the rotating brush Ql. The polishing device body (5) is directly driven by the motor (20).
), it goes without saying that the configuration can be similarly applied to a configuration in which the microphone (30) is lowered, and furthermore, the microphone (30) needs to be disposed in the brush motor (15) so as to prevent noise from entering. In addition, Figures 4 and 5 show the brush motor (15
) shows an example of the frequency analysis of the sound generated. Figure 4 shows the case when there is no load, and Figure 5 shows the case when there is a load. It is clear that the frequency band when the load is 9 is wider than the frequency band when there is no load. It has a certain quality. In this case, the brush motor is cage type 0.75K

(Effects of the Invention) As is clear from the above description, the present invention utilizes the change in the sound generated by the brush motor that occurs when the end face of the rotating brush that descends while being rotated by the brush motor starts contacting the workpiece surface. The machined surface is defined by the end face of the rotary brush, which stops at the same time.This enables automatic detection of the machined surface. It is possible to detect the workpiece surface extremely easily and in a short time without the need for the conventional procedures when making adjustments.Moreover, the changes in the sound generated by the brush motor are extremely sensitive, making it possible to accurately detect the surface being machined. It is capable of detecting the surface to be machined and solves the problems of conventional methods and devices for detecting the surface to be machined in deburring and polishing machines, making a great contribution to the development of the industry.
