2. Description of the Related Art In the above-mentioned mortise machine, the actual opening flat 3-6 is used.
A saw blade opening and closing fixing mechanism described in Japanese Patent No. 4706 is known. These are the columns 41, 4 standing on the base as shown in FIG.
A vertical saw blade 43 and a horizontal saw blade 44 are provided slidably to the left and right on a processing head 40 that moves up and down along 1.
In a pair of sliding bodies 42 and 42 having arms, an arm 45 pivotally supported on both sides of the processing head 40 and a link 46 pivotally supported on both sliding bodies, respectively, are pivotally connected by pins 47, and the pivotal connection portion is provided. Is provided with a split groove 48, and a lever 49 is screwed together.
The left and right sliding members 42 and 42 are respectively slid by the horizontal operation of 9, and the split groove 48 is tightened by rotating the lever 49 to tighten the pin 47, thereby fixing the sliding members 42 and 42.

[0003]

In the tenoning machine, the grip of the elevating lever for moving the machining head 40 up and down and the power switch are provided on one side of the tenoning machine (usually on the right side in FIG. 4). The worker stands on one side of the tenon machine provided with the lifting lever or the like and performs the work. However, in the above-mentioned tenon machine, when opening and closing the saw blade, it is necessary to operate each of the left and right levers 49 of the processing head 40. Therefore, the operation of the lever on the opposite side requires the operator to move or lean out of the body. It is not possible to do this unless it is troublesome and the workability is extremely poor. In addition, in the above-mentioned tenon machine, the fixing of the sliding members 42, 42 is performed by rotating the lever 49 itself screwed into the split groove 48 with a screw.
The operability is not good either.

[0004]

[0005]

Since both levers for operating the left and right slides are provided on one side of the processing head, the operator can slide and fix both slides on the spot. That is, when the lever is rotated in the direction of loosening the screw member with the screw member as a fulcrum, the clamp body becomes rotatable, so if the lever is horizontally rotated as it is, the clamp body and the arm rotate integrally, and simultaneously the link member is rotated. The sliding body also slides through. When the lever is rotated in the tightening direction at an arbitrary position, the screw member is fixed to the rotating shaft by tightening the clamp body, and at the same time, the slide of the slide body is locked. Since these operations can be easily performed by rotating the lever, the operability is good.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of a processing head, and FIG. 2 is an explanatory view of a right side surface. The processing head 1 is penetrated by a pair of columns 2 and 2 erected on a base (not shown), and extends along the columns 2 and 2. Guide part 3 which moves up and down, vertical saw blades 4 and 4, and horizontal saw blades 5 and 5, respectively.
And a pair of sliding bodies 6 and 7 having the following. Guide part 3
On the side of the sliding bodies 6 and 7, a pair of connecting portions 8 and 8 are protruded, and a hollow pipe 9 is bridged between the connecting portions 8 and 8; A pipe 10 parallel to the pipe 9 is provided between 8a. Further, the upper and lower pipes 9 and 10 are provided with sliding portions 6 protruding from the respective sliding members 6 and 7 toward the guide portion 3 with the upper and lower connecting portions 8 and 8a interposed therebetween.
a, 6a, 7a, and 7a, respectively, and the sliding members 6, 7 are supported by the upper and lower pipes 9, 10 so as to be slidable left and right by this configuration. One end of a link 11 is rotatably mounted on the upper surface of the right sliding portion 6a of the sliding body 6 by a bolt 12, and the other end of the link 11 is a tip of a rotating arm 22 of a clamp mechanism 15 described later. It is attached to the shaft. Similarly, the sliding portions 6a, 7a of the left and right sliding members 6, 7 are horizontally inserted between the upper and lower pipes 9, 10 to the side of the left sliding portion 7a of the sliding member 7. One end of the long second link 13 is rotatably mounted on a shaft by a bolt 14, and the other end of the second link 13 is mounted on a tip of a rotating arm 22 of the lower clamp mechanism 15.

FIG. 3 shows details of the clamp mechanism 15. Since the upper and lower clamp mechanisms have the same structure, only the upper one will be described. A clamp body 17 is rotatably mounted on a support base 16 protruding to the right side of the guide portion 3 by a fixing pin 18. An upper portion of the clamp body 17 has an insertion hole for the fixing pin 18. Vertical split grooves 19 communicating with each other
Is provided, and the clamp pieces 20a and 20b are respectively provided so as to protrude.
A rotating arm 22 attached to the shaft 1 extends. Further, a tightening bolt 23 having a corresponding step portion passes through the stepped hole provided in the clamp piece 20b horizontally, and a screw portion 23 at the tip end.
a is screwed into the clamp piece 20a, while the tightening bolt 23
A fixing portion 26 of the operation lever 25 is provided at the other end of the split groove 2.
4 are orthogonally tightened by bolts 27 for tightening. Therefore, according to this structure, by moving the free end side of the operation lever 25 up and down, the tightening bolt 23 is rotated, and the clamp piece 20a with which the screw portion 23a is screwed is fed. When the operating lever 25 is lowered, the clamp piece 20a is screw-fed to the clamp piece 20b side to tighten the fixing pin 18, and when the operating lever 25 is raised, the clamp piece 20a is screw-fed to the opposite side to fix the fixing pin 18. 18 tightened. Further, a stopper 29 that regulates the lower limit position of the extended portion 28 protruding from the fixed portion 26 of the operation lever 25 upward of the rotary arm 22 in order to prevent excessive tightening when the operation lever 25 is operated downward is prevented. At the same time, a compression spring 30 is interposed between the extending portion 28 and the rotating arm 22 to prevent the operation lever 25 from lowering by its own weight.

In the tenoning machine configured as described above, when the operation lever 25 of the upper clamp mechanism 15 is raised upward from the lower limit position when adjusting the interval between the saw blades, the clamp body 17 is rotated by the tightening bolt 23. The tightening of the fixing pin 18 is loosened, and the clamp body 17 becomes horizontally rotatable. Therefore, when the operation lever 25 is horizontally rotated in any horizontal direction as it is, the rotary arm 22 rotates with the fixing pin 18 as a fulcrum, and at the same time, the sliding body 6 connected via the link 11 slides and moves to an arbitrary position. Can be moved.
When the operation lever 25 is lowered after the position of the saw blade is determined, the clamp body 17 tightens the fixing pin 18 by the rotation of the tightening bolt 23 to lock the rotation of the rotary arm 22, so that the slide body 6 is also fixed at this position. Is done. This operation is the same for the lower clamp mechanism 15. The vertical movement and horizontal rotation of the lower operation lever 25 cause the left sliding body 7 to move.
Slides via the second link 13 and can be fixed at any position. As described above, in the present embodiment, the operator operates the operating levers 25, 25 of the upper and lower clamp mechanisms 15, 15 on one side of the processing head 1 to move the left and right sliding members 6, 7 without moving. This makes it possible to greatly improve workability. Further, the fixing can be performed simply and quickly because only the vertical movement of the operation lever 25 is required, and good operability is obtained. In this embodiment, the sliding members 6, 7
When sliding the upper and lower operating levers 25, 25
Since the horizontal rotation directions are opposite to each other, the angles of the lower rotation arm 22 and the operation lever 25 are set slightly outward from the upper rotation arm 22 as shown in FIG.

Further, as shown in FIG. 3, in the right sliding member 6, a long bolt 31 is screwed from the connecting portion 8 and a short bolt 32 is screwed in parallel from the right sliding portion 6a. Abuts on the connecting portion 8 by sliding the sliding body 6 inward to regulate the sliding body 6 inward,
The long bolt 31 penetrates the through hole 6b provided in the sliding portion 6a and locks the locking metal member 33 pivotally attached to the outside of the sliding portion 6a, so that the sliding member 6 slides outward. By the head 31
a locks with the locking member 33 (FIG. 2), and regulates the sliding body 6 to slide outward. Since the long bolt 31, the short bolt 32, and the locking member 33 are also provided between the connecting portion 8 and the sliding portion 7a in the left sliding body 7, the scale plate 34 fixed to the front surface of the guide portion 3 is provided. When,
Together with the corresponding needle 35 on the upper surface of the sliding portion 6a, it serves as a guide for the sliding movement of the sliding body, thereby facilitating the operation.

Although the clamp mechanism is tightened by screwing the split groove of the clamp body and the tightening bolt, the tip of the tightening bolt screwed to the clamp body is directly brought into contact with the fixing pin, and the operation lever is operated. Other fixing mechanisms, such as fixing and releasing the clamp body by changing the pressing force to the fixing pin by the rotation of the tightening bolt by the operation, may be adopted. Further, the slide support between the guide portion and the slide body is not limited to a hollow pipe, and the present invention can be applied to other slide structures using rails or the like.

[0011]

As described above, according to the present invention, the sliding movement of the left and right sliding bodies and the fixing operation can be performed on one side of the processing head, so that the opening and closing of the saw blade can be quickly performed with good workability. Also, the sliding operation of the sliding body is realized by the clamp body and lever.
Since it is, can slide with fixed slide body with a simple rotational operation of the lever, the operability is improved.
