Description

[Detailed Description of the Invention] [Industrial Application Field] In the present invention, an elevating section consisting of a rotary planer barrel driven by a motor and a feed roller that is pivoted can be moved up and down from a surface plate by operating a handle. This parting stopper for an automatic plane is provided to be moved up and down guided by a pair of up/down screw rods erected on the left and right sides of the machine.

[Conventional technology]

The above-mentioned automatic plane is configured so that the lifting section is moved up and down with a pair of left and right lifting threaded rods according to the thickness of the material to be cut, relative to the surface plate provided at the bottom of the main body. For the purpose of cutting a large number of materials to be cut of a constant thickness, the machine is provided with a stopper for stopping the lifting section at a predetermined height relative to the surface of the surface plate.

Conventionally, as the dividing stopper, there are a method in which the stopper is fixed to the elevating part with a thumbscrew, a method in which a threaded rod is inserted, a method in which the elevating threaded rod is fixed, and the like.

[Problem that the invention attempts to solve]

However, in the existing dividing stoppers, the bar-shaped stopper and the lifting screw rod are directly fixed with screws, so when the handle that moves the lifting part up and down is turned strongly, the downward force of the lifting part is applied to the stopper. As a result, the stopper tends to slip, which causes a common problem in that the determining surface is likely to become distorted.

The present invention is an attempt to solve the above-mentioned problems.A stopper bolt is screwed into a protrusion protruding from the elevating part, and the lower end surface of the stopper bolt is formed as a parting surface for the stop surface of the surface plate. In addition, by providing a threaded hole in the protrusion and incorporating an elastic body that can interfere with the stopper bolt and adjust its compression with a push screw, the stopper bolt will not slip or shift. Since there is no looseness and the elastic body prevents loosening, once the portion is set, the portioning can be maintained with high precision and no errors occur, and the stopper bolt is placed near the lifting screw rod. The purpose of this is to make it difficult for back and forth and left and right backlash to occur, and to simplify the structure so that it can be manufactured at a low cost.

[Means for solving problems]

That is, the present invention provides an automatic plane in which a rotating plane body driven and rotated by a motor and a lifting section equipped with a feed roller are raised and lowered relative to a surface plate by a pair of lifting screw rods provided on the main body. A protrusion is provided protruding from the elevating part near the elevating threaded rod, a stopper bolt is threadably inserted into the protrusion, and its lower end is connected to the stop surface of the upper surface of the surface plate. On the other hand, the protrusion is provided with an elastic body in a concave hole intersecting with the screw hole thereof so as to be able to interfere with the stopper bolt, and the elastic body is pressed so as to be compressible and adjustable. The above-mentioned problem was solved by screwing the screws together.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings. As shown in FIGS. 1 to 3, the main body 1 has an upper cover 3 fixedly mounted on the upper ends of the left and right guide members 2 and 2'. The main body 1 has a substantially gate-shaped front surface, and a surface plate 4 is horizontally fixed to the lower end of the main body 1. A pair of lifting threaded rods 5,
5' are fitted into the vertical holes 6a, 6'a of the holders 6, 6' whose upper and lower ends are fixed to the upper cover 3, and into the recessed holes 7, 7' of the surface plate 4, respectively. handle shafts which are rotatably and vertically arranged side by side, and fitted into the horizontal holes 6b, 6'b of both the holders 6, 6', and are rotatably and horizontally installed on the upper part of the main body 1; 8 and a pair of lifting screw rods 5, 5' are interlocked and connected by meshing with bevel gears 9, 9', 10, 10' fixed respectively. 5'.

The pair of elevating screw rods 5, 5' has an elevating section 11.
However, screw holes 12, 1 are provided through the left and right ends of the screw holes 12,1.
2', so that it can be moved up and down by the rotation of the up/down screw rods 5, 5'.

The elevating section 11 includes a motor 13 and a rotary planer barrel 1 driven and rotated by the motor 13.
4, and two feed rollers 15, 15' arranged in the front and rear of the rotary planer body 14 are pivoted in parallel in the left-right direction.

Further, both left and right ends of the elevating part 11 are fitted into the left and right guide members 2, 2' so as to be slidable in the vertical direction, thereby preventing rotational movement in the horizontal direction. As a result, the elevating section 11 is moved up and down in a predetermined direction.

Furthermore, compression springs 16, 16' are mounted on the lower portions of the pair of lifting screw rods 5, 5', and the lifting section 11 is balanced by the compression springs 16, 16'.

A protrusion 17 is provided to protrude outward approximately horizontally from either the left or right end (in the illustrated example, the right end) of the elevating section 11, and on the other hand, the protrusion 17 of the main body 1 protrudes. A stopper bolt 18 is screwed into the threaded hole 17a of the protrusion 17 so that it can rotate and slide freely in the axial direction (vertical direction) near the lifting threaded rod 5'. The stopper bolt 18 is vertically arranged so that its lower end surface abuts the upper surface of the surface plate 4, and the upper surface of the surface plate 4 is set as a stop surface a, and the lower end surface of the stopper bolt 18 is separated. They are formed on surface b, respectively.

The protrusion 17 is laterally provided with a recess 19 which crosses and communicates with the inner end at a substantially right angle to one side of the screw hole 17a.
Alternatively, an elastic body 20 made of urethane rubber or the like that can be elastically restored to its original shape is installed inside the concave hole 19 so as to be able to interfere with the stopper bolt 18 via a communicating portion 19a with the screw hole 17a of the concave hole 19. At least the opening side of 19 is formed in a screw hole 19b, into which a push screw 21 is screwed so that the elastic body 20 can be compressed and adjusted.

Further, the upper end portion of the stopper bolt 18 is provided in a tool attachment portion 18a having an oval or arbitrary polygonal cross-sectional shape, and is formed so that a tool 22 can be detachably fitted thereinto. , the stopper bolt 18 has a length such that the upper end still protrudes upward from the upper surface of the main body 1 by a desired length even at the lower limit where the dividing surface b of the lower end abuts against the stop surface a. is formed.

In the illustrated example, the stopper bolt 18 is inserted into a hole 3a formed in the upper cover 3 so as to be rotatable and movable in the vertical direction.

In addition, a plurality of rollers 23, 23', 24, 24' are pivotally supported on the surface plate 1 and on both front and rear sides of the surface plate 1, respectively, for smooth feeding of the workpiece W. be.

In the above configuration, when the handle 8a is rotated in one direction, the pair of elevating threaded rods 5, 5' rotate in conjunction with the handle shaft 8, and the elevating portion 11 screwed with the threaded rods 5, 5' rotates. is descending.

Also, since the lifting section 11 is raised by rotating the handle 8a in the opposite direction to that described above, the lifting section 11 is lowered as described above depending on the thickness of the workpiece W placed on the surface plate 4. As a result, the workpiece W is fed in one direction by the feed rollers 15 and 15' driven and rotated by the motor 13, and the plane blade 14 of the rotary plane body 14 is driven and rotated in this feeding operation process.
The workpiece W is cut by a...

At this time, the stopper bolt 18 is raised to a desired position so that the dividing surface b of the stopper bolt 18 does not abut against the stop surface a.

Next, when cutting a large number of workpieces W of a certain thickness in succession, screw the stopper bolt 18 with the tool 22 in advance so as to correspond to the thickness of the workpiece W, and The dimension between the deciding surface b and the stopping surface a of the surface plate 4 is determined in advance.

Next, when the handle 8a is rotated to lower the elevating section 11, the workpiece W is cut by the rotary plane barrel 14, and when the dividing surface b hits the stop surface a, the elevating section 11 is lowered. is stopped, so the material to be cut W is cut to a constant thickness.

In order to further cut another workpiece W, the single-lifting part 11 is raised, and after setting the uncut workpiece W on the surface plate 4 instead of the cut workpiece W, the machine moves again. When the elevating part 11 is lowered, the material is cut to a constant thickness in the same manner as described above.

Further, when the push screw 21 is screwed into the recessed hole 19, the elastic body 20 is compressed and deformed, so that the elastic body 20 is connected to the communication portion 1 between the screw hole 17a and the recessed hole 19.
9a to the screw hole 17a side and is crimped onto the stopper bolt 18, so the frictional force between the stopper bolt 18 and the protrusion 17 increases due to the crimping force, so that the stopper bolt 18 Even if the stopper bolt 18 becomes loose due to vibration or is strongly pressed against the stop surface by strongly rotating the handle 8a, the stopper bolt 18 will not slip in the axial direction.

[Effect of idea]

As explained above, the dividing stopper of the automatic planer according to the present invention is constructed so that the stopper bolt 18 screwed through and attached to the protrusion 17 of the elevating part 11 is attached to the screw of the protrusion 17. Hole 17a
The stopper bolt 18 is prevented from loosening by interfering with the recessed hole 19 that is provided in communication with the stopper bolt 18 by an elastic body 20 that can be compressed and adjusted with a push screw 21. bolt 18
The handle 8 is also used as a threaded bolt to prevent vibrations during cutting and to force the handle 8 in the direction in which the lifting section 11 descends.
When turning a, etc., the stopper bolt 18
There will be no slippage or rotation of the cutting surface, and therefore, there will be no deviation in the parting determined by the dimension between the stopping surface a and the parting surface b, and the thickness of the material W to be cut will be reduced. Depending on the situation, the stopper bolt 18 can be easily and accurately adjusted by simply rotating the stopper bolt 18 with the tool 22, and the above-mentioned stopper bolt 18 can be adjusted easily and with high accuracy. By attaching it near the rod 5 or 5', it is less likely to cause backlash in the front-rear, left-right directions, and has practical effects such as being structurally simple as it consists of only a few basic parts and can be manufactured at low cost. There is.
