Description

[Detailed Description of the Invention] The present invention relates to a cushion mechanism in a super-finishing plane for applying the desired cutting pressure to the workpiece to the plane blade.

As shown in FIG. 1, the conventional cushion mechanism includes a female screw fixed to a frame 4, in which a vertically movable screw 3 is rotatably arranged through a bed portion 1 supporting a plane blade with a handle boss 2 interposed therebetween. By screwing into the screw 5, the female screw 5 and the frame 4
A pressure spring 7 is inserted between the pressure adjustment nut 6 screwed onto the
interposed so that the pressure on the workpiece W acts indirectly through the vertical movement screw 3, female screw 5, lifting handle 8, and handle boss 2, or as shown in FIG. As shown, the vertical movement screw 3 is disposed through the bed part 1 and screwed into the frame 4, and the bed part 1 is screwed into the frame 4.
and a pressure adjustment nut 6 screwed onto the upper part of the bed portion of the vertical movement screw 3, and a pressure adjustment nut 6 is interposed between the spring pressure and the pressure adjustment nut 6, so that spring pressure is directly applied to the workpiece W. etc. have been implemented, and the former is the latter,
Although it can be said to be effective in that a stable pressing force can be obtained by applying spring pressure directly to the workpiece W, both the former and the latter have the disadvantage that the height of the machine becomes large and the operability is poor. .

Therefore, the present invention improves the cushion mechanism in order to avoid the above-mentioned conventional difficulties, and improves the ability to apply pressure to the workpiece,
The purpose is to make it possible to improve the operability of the machine.

The drawings showing the embodiments of the present invention will be described in detail below.

First, as shown in FIGS. 3 and 4, the super finishing nameplate A has a plurality of rollers 13...
. . . and a material feeding mechanism 17 formed by supporting pulleys 14 and 15 in the front and rear, respectively, and wrapping an endless belt 16 around it, is provided to be driven and rotated by a motor 18. A name plate holder 21 holding a fixed name plate 20a and a plate 20b is moved up and down in the upper direction of the material feeding mechanism 17. It is arranged and configured as possible.

Thus, as clearly shown in FIG. 4, the cushion mechanism B of the present invention has a lifting bolt 22 fixed to the arm 12 in the axial direction, and a threaded portion 22 attached to a rotatably installed lifting nut 23. A is screwed together and arranged, and a threaded part 22b is disposed through the nameplate holder 21 to prevent rotation, and is provided at the tip of the lifting bolt 22 protruding from the nameplate holder 21. Screw together the adjustment nut 24, and
A cushion spring 25 is interposed between the name plate holder 21 and the name plate holder 21 to support the name plate holder 21 so as to be movable up and down, and further,
The lifting handle shaft 26 is attached to the frame 10 at the shaft bearing part 35.3.
5 is installed horizontally, and the handle shaft 26 and the lifting nut 23 are interlocked and connected by a gear transmission mechanism 27.

That is, the lifting nut 23 is fitted into the mounting hole 28 provided through the arm 12 with the bearing 29, 29 interposed therebetween, fixed in the axial direction by a retaining plate 31 secured with screws 30, and rotatably. A bevel gear 32 is arranged and fixed to the lower end thereof and to the lifting handle shaft 26, respectively.
．． 33 are engaged with each other to interlock with the lifting handle shaft 26, and the other end of the lifting handle shaft 26 protrudes from the side surface of the frame 10 to fix the handle 26. The lifting nut 23 is rotated by the rotational operation, and the lifting bolt 22, which is threaded through the screw hole 23a, is moved up and down.

Further, the lifting bolt 22 is slidably passed through the mounting hole 21a provided through the copper plate holder 21 in the axial direction, and the flange portion 22C and the copper plate holder 21 are hooked with a pin 34, and the bolt 22 is rotated. is to be prevented.

Further, the portion of the copper disc holder 21 that supports one end of the cushion spring 25 is formed in a substantially annular recess 36 on a thousand sides concentric with the mounting hole 21a, and a portion between the bottom 36a and the adjustment nut 24 is formed. A cushion spring 25 is interposed to support the lifting bolt 22 so that it does not protrude from the upper surface of the copper plate holder 21 as much as possible.

In the above configuration, the distance between the material feeding mechanism 17 and the copper disc holder 21 is adjusted in advance to be narrower than the height H of the workpiece W to be cut, and the workpiece W is cut in this state. When conveyed, the copper disc holder 21 is pushed up.

At this time, the lifting bolt 22 is the lifting nut 2 of the arm 12.
3, the lifting bolt 22 is held at a predetermined position without moving up and down, so the cushion spring 25 is compressed and the copper plate holder 21 rises against its elastic force. However, as a result, an appropriate cutting pressure is applied to the workpiece W.

Further, the above cutting pressure can be adjusted by adjusting the adjustment nut 24 by adjusting the lifting bolt 2.
It can be adjusted to a desired value by screwing forward and backward with respect to the threaded portion 22b of No. 2.

Furthermore, the distance between the material feeding belt 17 and the copper disc holder 21 needs to be adjusted according to the height H of the workpiece W to be cut, but adjustment in this case can be done by rotating the handle 26'. By transmitting the rotational force of the shaft 26 to the lifting nut 23 via the gear transmission mechanism 27, the lifting bolt 22 is moved up and down by the lifting nut 23 rotating at a fixed position.

As explained above, according to the cushion mechanism for the super-finished copper disc according to the present invention, the cushion spring 25 is interposed between the adjustment nut 24 screwed to the lifting bolt 22 and the copper disc holder 21, and the copper disc holder is 21 is directly pressurized by the cushion spring 25, there is no operation loss that occurs when indirectly machining is performed using multiple members, and the cutting pressure of the set value adjusted in advance by the adjustment nut 24 is applied to the workpiece W. In addition, the lifting bolt 22 can be fixed and the lifting nut 23 screwed with the lifting bolt 22 can be attached to the arm. Since the lifting nut 23 is rotatably supported on the frame 10 and is interlocked with the lifting handle shaft 26 horizontally suspended on the frame 10 by the gear transmission mechanism 27, when adjusting the lifting and lowering of the copper plate holder 21, the lifting nut 23 can be adjusted using the conventional lifting bolt. According to the present invention, by fixing the lifting bolt 22, the cutting pressure by the cushion spring 25 can be adjusted to the set value. Since the lifting handle 26' can be disposed on the side of the frame 10, the operability when lifting and lowering the copper plate holder 21 is not only improved, but also the cutting pressure can be further stabilized. Lifting bolt 22
Unlike the conventional example, the handle is not provided with a handle that protrudes upward for a long time, and since it does not move up and down by screwing, it can be installed at a predetermined position and low, making it possible to reduce the height of the machine. It has many great effects.
