昇降ほぞ取り機に関するものである。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention provides an automatic lifting and tenoning machine equipped with an upper and lower limit detection device for automatically lifting and lowering a cutting head having vertical and horizontal circular saws. It is related to.

不慮の事故を招きやすい等の問題があった。In order to save labor and improve the efficiency of mortise removal work, an automatic lifting and tenon replacement system as shown in FIG. 3 is currently provided. In the conventional technology, a mole for lifting and lowering is set upright on a bridge, and a feed screw for lifting and lowering fixed to a cutting head is also screwed into a female thread provided on the bridge and protrudes upward. . Therefore, since the elevating motor is located on the bridge, the product becomes large in size, and when the cutting head is at its upper limit, the elevating feed screw protrudes upward by the amount of movement of the cutting head. For this reason, there are problems in that the workplace is restricted, and the movable member protrudes from the outer frame of the main body when going up and down, which tends to lead to unexpected accidents.

重に弱く、容易に変形してしまい上下限検出が正常に働
らかない等の問題があった。Regarding the upper and lower limit detection devices, in the prior art, limit bars are vertically disposed downward from the bridge. The length of the cutting head must be longer than the amount of movement of the cutting head, and it is cantilevered from the bridge. Therefore, when the cutting head is at its upper limit, a considerable length protrudes, which prevents external loads. There were problems such as being weak and easily deformed, preventing upper and lower limit detection from working properly.

にある。An object of the present invention is to make the product compact, to process the movable member within the main body frame so that it does not protrude from the main body outer frame during the vertical movement, and to further improve the reliability of the upper and lower limit detection device.

るようにしたものである。In the present invention, in order to make the product compact, the lifting motor is placed on the cutting head, and the lifting feed screw is fixed downward from the bridge and is fitted into a female thread that is linked to the lifting motor attached to the cutting head. The upper and lower limit detection limit bars and limit switches are installed on the cutting head, and the limit bar is supported on both sides of the cutting head so that the upper and lower limit positions can be detected with a length that is independent of the amount of movement. This is how it was done.

備した切削ヘッド６が上下摺動可能に嵌合されている。An embodiment of the present invention will be described using FIG. 1.2. A guide bar 2 is vertically disposed on a base 1 and its upper end is held by a bridge 3. A cutting head 6 equipped with a vertical circular saw 4 and a horizontal circular saw 5 is fitted into the guide bar 2 so as to be vertically slidable.

に１３を係合させる。The cutting head 6 is equipped with a lifting motor 7 and a transmission device, and the final shaft of the transmission device is a feed gear 8 having a female thread. In addition, a feed screw 9 is fixed to the bridge 3 so as to be screwed into the feed gear 8, and a limit par IQ is inserted into a part of the cutting head 6 that forms an elevating device so as to be slidable up and down. A return means is provided at both ends of the par 10 so that the limit par 10 returns to its original position after being moved up and down by winding compression springs 11. In addition, a recess is formed in the center of the limit par 10, and the limit switch 13 is engaged with a limit switch that detects the upper and lower limits.
ブリッジ３及びベース１にはリミットパー１０が上下限
位置で当接するような突き当て部材を設ける。Abutment members are provided on the bridge 3 and the base 1 so that the limit pars 10 abut at upper and lower limit positions.

When the lower limit position is reached, the limit par 10 comes into contact with the base 1 and is pushed up, turning on the lower limit switch 13, cutting off the power to the lifting motor 7, and stopping the lowering. When the lift switch is turned on, the lift motor 7 rotates in reverse (forward rotation), the feed gear 8 rotates in the reverse direction, and the cutting head 6 rises. At this time, the limit par 10 returns to the neutral position due to the biasing force of the upper compression spring 11. At the upper limit position of the cutting head 6 which is rising, the limit par 10 comes into contact with the bridge 3 and is pushed down, turning on the upper limit switch 12, cutting off the power to the lifting motor 7 and stopping the lifting. When further lowered, the limit par 10 returns to the neutral position due to the biasing force of the lower compression spring 11.

By hanging the feed screw downward from the bridge and placing the upper and lower limit detection device on the cutting head, the product can be made more compact.It also prevents unexpected accidents caused by the feed screw protruding, and further increases the reliability of the upper and lower limit detection device. This can greatly improve performance.
