43
each extended through the slide seat
42 to move in parallel with the Y-axis
direction, a slide box
44 fixed on the two radial displacement rods
43
to move therewith, and an elastic member
45 mounted between a side
421
of the slide seat
42 and a side
441 of the slide box
44, so
that the slide box
44 is constantly moved toward the support bar

box
7 through the opening
71 and can be drained outward from the
chip drain hole
75. Thus, the operator can inspect the chip drainage condition
of the dust collection box
7 through the transparent window
73.
In operation, the motor
51 drives the blade
52 to rotate. Thus,
the slide box
44 can be pushed or pulled in a manual manner, so that the
slide box
44 and the slide seat
42 can slide on the axial displacement
rods
41 to move in parallel with the X-axis direction, or the slide box
44 and the radial displacement rods
43 can slide on the slide seat
42 to move in parallel with the Y-axis direction. Thus, the slide box
44
can moved in parallel with the X-axis direction and in parallel with the Y-axis
direction arbitrarily.
Thus, the molding bar
62 is moved with the slide box
44 to displace
in parallel with the X-axis direction and in parallel with the Y-axis direction
arbitrarily, so that the molding end
621 of the molding bar
62 can
be moved along the periphery of each of the tenons
32 of the support bar
3. Thus, the slide box
44 can be moved along the track of the molding
end
621 of the molding bar
62 to drive the blade
52 to move
along the track of the molding end
621 of the molding bar
62 so as
to cut mortises
81 and tenons
82 in the workpiece
8 according
to the profile and distance of the tenons
32 of the support bar
3,
so that the mortises
81 and tenons
82 of the workpiece
8 can
match the relative profile and distance of the respective tenons
32 of the
support bar
3.
In addition, the slide box
44 is constantly moved toward the support bar
3 by the elastic force of the elastic member
45, to prevent the molding
end
621 of the molding bar
62 from detaching from the support bar
3, so that the molding end
621 of the molding bar
62 can align
with the corresponding working position of the support bar
3 easily and conveniently.
Further, the four side faces
31 of the support bar
3 are provided
with tenons
32 of different forms and distance, so that the molding end
621 of the molding bar
62 can be moved along the tenons
32
of different side faces
31 of the support bar
3 so as to cut mortises
81 and tenons
82 of different forms and distance.
Referring to FIG. 6, the elastic member
45 includes a bolt
451
screwed through a rear wall
442 of the slide box
44 along the Y-axis
direction, and a compression spring
452 urged between the bolt
451
and the slide seat
42. Thus, the compression spring
452 can push
the slide box
44 backward along the Y-axis direction, so that the slide
box
44 is constantly moved toward the support bar
3.
Referring to FIG. 7, the elastic member
45 includes a press cylinder
453 extended through the rear wall
442 of the slide box
44
along the Y-axis direction, and a piston rod
454 secured on the slide seat
42 and retractably mounted on the press cylinder
453. Thus, the piston
rod
454 can be retracted to drive the slide box
44 to move backward
along the Y-axis direction, so that the slide box
44 is constantly moved
toward the support bar
3.
Referring to FIGS. 8 and 9, the semi-automatic mortising machine in accordance
with another embodiment of the present invention further comprises an indication
device
9.
The support base
2 includes a plurality of press cylinders
25 for
pressing the workpieces
8. The support bar
3 is located under the
platforms
22 and
23. The distance adjusting device
6 is mounted
on a bottom face of the slide box
44. Thus, the distance adjusting device
6 can drive the working device
5 to cut the mortises
81 and
tenons
82 in the workpiece
8 according to the profile and distance
of the tenons
32 of the support bar
3, so that the mortises
81
and tenons
82 of the workpiece
8 can match the relative profile and
distance of the respective tenons
32 of the support bar
3.
The indication device
9 includes an indication bar
91 secured on
a front end
211 of the side wall
21 of the support base
2,
and a direction bar
92 secured on the slide box
44 and located above
the indication bar
91. The indication bar
91 has a top face
911
and a bottom face
912 each formed with a plurality of recesses
913
whose spaced distance is equal to that of the tenons
32 of the support bar
3. Thus, when the slide box
44 is moved along the track of the tenons
32 of the support bar
3, the direction bar
92 is moved with
the slide box
44 in the X-axis direction, so that the direction bar
92
can align the position of each of the mortises
81 and tenons
82 of
the workpiece
8 with that of the respective recess
913 of the indication
bar
91, so as to indicate the working condition of the workpiece
8
by the indication bar
91.
Accordingly, the semi-automatic mortising machine in accordance with
the present invention has the following advantages.
The displacement direction can be controlled in a manual manner during the working
process, and the cutting operation is performed in an automatic manner, so as to
cut the mortises
81 and tenons
82 in the workpiece
8. Thus,
the construction of the semi-automatic mortising machine is largely simplified.
In addition, the semi-automatic mortising machine can reduce the possibility of
malfunction. Further, the semi-automatic mortising machine can facilitate maintenance.
Further, the semi-automatic mortising machine can maintain the quality of the products.
Although the invention has been explained in relation to its preferred embodiment(s)
as mentioned above, it is to be understood that many other possible modifications
and variations can be made without departing from the scope of the present invention.
It is, therefore, contemplated that the appended claim or claims will cover such
