CONSTITUTION:A workpiece W is placed on an y-axis table 3, and x-axis and y-axis tables 2 and 3 are moved to a given position by means of an air cylinder. A portal type device 4 and a machining head 5 are moved to a position situated facing the workpiece W, and with a motor 6 turned ON, a rotary cutter 7 is rotationally driven. Thereafter, a head 5 is moved downward with the aid of an air cylinder 12, a cutter 7 is forced into contact with the burrs of the workpiece W, and the workpiece W is moved to cut off the burrs. In this case, since the cutter 7 can swing within a range where the side wall of the motor 6 makes contact with the under surface 14b of a peripheral wall 14, if unevenness of the surface of the workpiece W is low, the cutter 7 is swung without control, e.g. NC, and follows the uneven surfaces of a reference surface W3 of the workpiece W with the aid of a guide roller 7a, and removes burrs without excessive cutoff.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a deburring machine for deburring a workpiece such as a plastic molded product.

<Prior art> Conventionally, deburring of a workpiece was mainly carried out manually using a tool such as a cutter.Furthermore, as a deburring machine, for example, the Japanese Utility Model Publication No. 59-124108
A machine like the one described in the publication was used.

As shown in FIG. 6, this type of deburring machine rotates the workpiece W and moves the tip of the actuating arm 21, which moves once in the direction away from the workpiece W, toward the workpiece W. The cutter 22 disposed at the tip of the working arm 21 is brought into contact with the workpiece W to remove burrs.

<Problems to be Solved by the Invention> However, when removing burrs by hand, the finish tends to be uneven due to burrs left behind or excessive removal, which requires skill. Moreover, this work was time consuming and inefficient.

In addition, in conventional machines, since the workpiece W is rotated,
For example, it was not possible to cut out the recess W1 of the workpiece W as shown in FIG. 5, and this had to be done manually.

Means for Solving the Problems> The present invention has been made in view of the above-mentioned problems, and is capable of efficiently cutting workpieces of various shapes and uniformly and neatly cutting end surfaces. The object of the present invention is to provide a deburring machine that can follow only the machining head if there is some unevenness on the workpiece, and is configured as follows.

That is, the deburring machine of the present invention includes a processing head that has a rotary cutter that cuts burrs and a motor that rotationally drives the rotary cutter, and a processing head that moves the processing head toward and away from the workpiece. a deburring machine comprising: a processing head rotatably supported by a processing head support member; and peripheral walls fixed to the processing head support member arranged at predetermined intervals around the outer periphery of the motor. An elastic member is provided in the gap between the motor and the peripheral wall to bias the motor in the axial direction.

<Example> Hereinafter, an example of the present invention will be described based on the drawings.
Various embodiments are possible without departing from the technical idea of the present invention.

FIG. 1 is a schematic front view of the deburring machine, and FIG. 2 is a partially cutaway side view of the processing head.

An X-axis table 2 that moves in the left-right direction of the machine 1 is arranged on the machine 1, and a y-axis table 3 that moves in the front-back direction of the machine 1 is arranged on the X-axis table z. A workpiece W is held on a y-axis table 3 and is movable back and forth and left and right.

Further, on the machine stand 1, a U-shaped gate 4 is disposed so as to be movable in the front-back direction of the machine stand 1, and on the upper side 4a of the gate 4, a processing head 5 is disposed so as to be movable in the left-right direction of the machine stand 1. is installed.

The processing head 5 is arranged so as to be movable up and down along a rail 11 arranged in the vertical direction of the machine stand 1 by an air cylinder (processing head moving means) 12 provided above. Further, a pole 10b passing through a substantially spherical rotating member 10a provided on one end side of the processing head support member 10 having a substantially angular cross section, that is, above the processing head 5, is a motor disposed on the upper surface of the processing head 5. The processing head 5 is screwed onto the support member 6a, and is pivotably supported by the processing head support member IO. Furthermore, the motor 6 of the processing head 5 is provided at its distal end portion, fixed to the lower end of the processing head support member 10 . This peripheral wall is a cylindrical member having a U-shape in cross section, and is disposed at a predetermined interval so that its upper surface 14a and lower surface 14b do not come into contact with the motor 6. Further, a tube 15 as an elastic member for urging the motor 6 in the axial direction is provided between the peripheral wall 14 and the motor 6, and the tube 15 is connected to an air intake port 14C provided on the outer periphery of the peripheral wall 14. When air flows into the tube 15 through an air pump (not shown) or the like, a predetermined amount of air is introduced into the tube 15 with a size that fills the gap between the peripheral wall 14 and the motor 6, and the motor 6 is moved along its axis. It can be biased toward the heart. A rotary cutter 7 is disposed at the tip of the motor 6, and a guide roller 7a having the same diameter as the rotary cutter 7 is disposed at the tip of the rotary cutter 7.

In addition, by changing the shape of the rotary cutter 7,
Chamfering etc. can be performed.

Next, the operation of the above embodiment will be explained.

First, the workpiece W is placed and held on the y-axis table 3, and the X-axis and y-axis tables 2 and 3 are moved to predetermined positions by NC (
It is moved by an air cylinder or the like (not shown) controlled by a numerical control device).

Next, the portal mold 4 and the processing head 5 are moved to a predetermined position corresponding to the workpiece W in the same manner as described above. Then, the motor b is turned on and the rotary cutter 7 is driven to rotate.

After that, the processing head 5 is moved downward by the air cylinder 12, the rotary cutter 7 is brought into contact with the ridge of the workpiece W, and the workpiece is moved to scrape off the burrs. After contacting the workpiece W, the processing head 5 can also be moved.

At this time, the rotary cutter 7 is configured such that the side wall of the motor 6 is connected to the peripheral wall 1.
4, the rotary cutter 7 can swing within the range where it comes into contact with the lower surface 14b of the workpiece W, so if the workpiece W has small irregularities, the rotary cutter 7 swings without being controlled by an NC or the like, and the guide roller 7a cuts the workpiece. It follows the irregularities of the reference surface W3 of W and can remove burrs without cutting too much.

Note that if the workpiece has small irregularities, it can be followed without the guide roller 7a.

Further, when chamfering a hole in a workpiece, even if the position of the hole is slightly shifted relative to the rotary cutter 7, the rotary cutter 7 can swing and chamfer the hole.

By increasing the distance between the peripheral wall 14 and the motor 6, the width of the swing becomes wider and it is possible to follow large irregularities.Furthermore, the amount of air put into the tube 15 allows the motor 6, that is, the rotary cutter 7, to be aligned with the axis. The force applied in the direction can be adjusted.

For example, as shown in Fig. 4, a small convex portion W on the workpiece
2, if the convex part W2 is not needed, put a large amount of air into the tube 15 to prevent the inflating motor 6 from swinging, and cut the workpiece so that the rotary cutter follows the side surface of the workpiece. If the body is moved in a straight line, the protrusion W2 can be removed together with the burr. Conversely, if the protrusion W2 is necessary, the motor 6 can remove the protrusion W2 by reducing the amount of air.
It can be adjusted so that it swings when it comes into contact with the

In addition, as an elastic member that urges the motor 6 in the axial direction,
A sponge or a spring can also be provided instead of the tube 14.

<Effects of the Invention> As explained above, since the deburring machine of the present invention has the above-described configuration, it is possible to perform deburring of various shapes of workpieces efficiently and with a uniform and clean cut end surface. .

Furthermore, even if there are some irregularities on the outer circumference of the workpiece, the machining head can swing to follow the irregularities, and the cutter will not dig into the workpiece or leave anything behind, making it possible to cut burrs. can be done.
