Description

[Detailed description of the invention] The present invention relates to a methi-wiping device.

More specifically, the present invention relates to an improvement in a device that performs edge removal while following the shape of the top and bottom surfaces of a workpiece such as furniture or a musical instrument, as well as the end surface facing the device.

Conventionally, a device for performing the above-mentioned five-point cleaning has a main shaft with the base ends of a pair of upper and lower arms supported on a column erected on the floor, and a cutter for cleaning at the tip of each arm. There is a type in which an integral copying roller is supported in a loose manner. More specifically, a spring is attached to the main shaft, which causes the copying roller to elastically press against the upper and lower surfaces of the workpiece, and moves the cutter in the Z direction (vertical direction with respect to the workpiece) by following the unevenness of the surface. It has a Z-direction image mechanism for moving the image.Furthermore, the proximal end of the copying swiss is fixed to a column between the upper and lower arms, and its tip is opposed to the end surface of the workpiece.

By the way, in the case of such a conventional edge removal device, since the copying stylus is fixed to the column at the base end, the main shaft and hence the cutter cannot move in the X direction (back and forth with respect to the workpiece). There is no. That is, it lacks the X-direction image function in which the main shaft and stylus are integrated.

In addition, since the copying roller cannot move in the Z direction in relation to the arm, fine adjustment of the edge removal amount is necessary, and the copying roller is parallel to the main shaft that supports the cutter, that is, the radial direction of the copying roller is parallel to the axial direction of the main shaft. be. The copying roller is placed closer to the workpiece than the main shaft. For this reason, the copying roller has to be separated from the cutting position by the cutter.If there are irregularities on the upper and lower surfaces of the workpiece that are very close to the cutting position, the copying roller will detect this. I can't.

It is an object of the present invention to provide a combing device that has an X-direction image function in addition to a Z-direction image function.

Another object of the present invention is to provide a multiplex payout device that can finely adjust the amount of multiplex payouts.

Still another object of the present invention is to provide a grooving device that can completely detect irregularities on the upper and lower surfaces of a workpiece, regardless of their locations.

That is, in this invention, a copying unit bracket is installed so as to be swingable in the Z direction with respect to at least one dovetail slide provided on the column, and a copying unit bracket is installed so as to be movable in the X direction with respect to the copying unit bracket. A main shaft for supporting the cutter is provided at one end of the inserted slide bar, and a motor for driving the cutter is provided at the other end.A copying roller and a stylus are attached to the main shaft. The stylus is always elastically pressed against the surface and the end surface of the workpiece.

More preferably, the copying roller is mounted movably in the Z direction with respect to the main shaft, and its position in the Z direction is determined by a screw type adjustment knob provided on the main shaft.

More preferably, the radial direction of the copying roller is inclined with respect to the axial direction of the main shaft, and the workpiece contacting side is brought closer to the edge removal cutter.

The present invention will be explained in more detail below with reference to embodiments shown in the accompanying drawings.

In Figures 1 and 2, the left side in the middle is the side facing the workpiece. In this section, we will explain the case of double-sided cleaning.A column 1 is erected on the floor, which serves as the foundation of the entire column, and in front of it, a guide strip is formed extending vertically.
This guiding strip meshes with a sliding groove formed on the back surface of the upper and lower dovetail slides 2a, 2b. Therefore, the upper and lower dovetail slides 2'a, 2b can move along the column 1 in the Z direction (in the vertical direction with respect to the workpiece).

A support shaft 3a is formed horizontally on the front surface of the upper dovetail slide 2a, and a copying unit Prokent 4a is loosely fitted onto this support shaft 3a. A spring 6a is interposed between the platen) 4a and the dovetail slide 2a, and the tensile force of the spring 6a urges the platen) 4a to rotate counterclockwise in the figure with respect to the support shaft 3a. The cutter and tracing roller are elastically pressed against the workpiece. Of course, the spring 6a is not necessarily a tension spring, and its elastic force may be utilized as a compression spring by changing the interposed part.

- Platinum) 4a has a slide par 7a extending horizontally in the X direction (back and forth direction with respect to the workpiece).

8a are loosely inserted in parallel, and these slide bars 7
a, 8a are fixed to the X-moving stylus 9a at the end on the workpiece side. Further, a fluid pressure cylinder 11a is installed horizontally on the front surface of the platen 4a, and is connected to a piston rod 12a+''! stylus 9a.

A main shaft 132L is installed integrally with the above-mentioned squirrel 9a, and the cutter 14 for edge removal is suspended from the lower section of the main shaft 132L.
a is boo! It is operatively connected to J 16a, and it is goo!
, 1-16a rotates to perform the cleaning operation. Also, the workpiece 1) 1 of the spindle 13a! l The lower end of the support bar 17a fixed at K has an H? The copying roller 18a is raised with a certain inclination. Further, the main shaft 13a has a support bar 17a and a copying roller 113a.
A screw-type adjustment knob 192L is provided for raising and lowering the main shaft 15a.

A main shaft drive motor 21a is fixedly supported at the opposite end of the slide pars 7a and 82L, and the drive motor 21a is fixed to the output shaft of the main shaft drive motor 21a. Operationally linked.

The structure of the lower dovetail slide 2b is the same as the upper dovetail slide 2.
Since it is only vertically symmetrical with the structure of a, its explanation will be omitted, and the same parts will be indicated in the drawings with the same reference honorific letters and symbols.

The payout device of this invention has the above-mentioned configuration,
This can be divided into two groups: an X-direction copying mechanism and an X-direction copying mechanism.

That is, taking the upper dovetail slide 2a as an example, the X-direction copying mechanism includes the slide pars 7a and 8a, the stylus 9ax, and the fluid pressure'/! The main cutter 14a is supported by a cutter 14a, a copying roller 18a, a motor 21a, and ancillary parts thereof. With the constant pressing operation of the fluid pressure cylinder 11a, the X-direction copying mechanism moves in the X-direction on the copying unit bracket 4a. During this movement, the spindle side gooley 16
Since the relative positional relationship between the cutter 14a and the motor side goo IJ-22a remains unchanged, the cutter 14a is driven by the motor 21a without any support.

The X-direction copying mechanism includes a support shaft 3a, a copying unit plate 4a, and a spring 6a. Upper He ShitaX
Since the cutter 14a is elastically pressed against the upper surface of the workpiece by the action of the spring 62L during the movement in the direction, the platen 4a moves about the support shaft 3a according to the unevenness of the core. That is, the two-direction copying mechanism moves in the KZ direction together with the X-direction copying mechanism that it supports. During this movement, the relative positional relationship between the main shaft side goo IJ-16a and the motor side boob 1)-22a does not change, so the cutter 14a is driven by the motor 21 without any support.

If a workpiece located at a certain x, y, and z position is moved, for example, in the Y direction, a corresponding deviation in the X direction will appear on the end face of the workpiece on the apparatus side. At this time, due to the movement of the fluid pressure cylinder, the X-direction copying mechanism operates and the whole moves in the KX direction to cancel out the deviation. Since the slide par is loosely inserted into the copying unit placenta, this movement is extremely easy. At this time, if there are irregularities on the upper and lower surfaces of the workpiece, the Y-direction copying mechanism is operated by the action of the spring, and the entire workpiece follows the irregularities and moves in the Z direction. Since the copying unit blanket is loosely fitted onto the support shaft, this movement is extremely easy.Therefore, it is possible to carry out extremely high-precision edge removal in both the X direction and the Z direction.

Furthermore, by operating the adjustment knob, it is possible to adjust the pitch of the screw to the extent that it can be removed by Kanku.

The vertical copying roller is tilted with respect to the main axis and its lower part approaches the cutter, making it possible to detect irregularities on the upper and lower surfaces of the workpiece even close to the edge removal position. can.

In the above, we have explained the case where the column is placed on the floor, but it may also be placed on a base that can be moved in the Y direction (left and right with respect to the workpiece) as appropriate. good.
