When the saw arm 14 is slid over the slider frame 15 by the sliders 16 in the slider 17, and is sawed at a position away from the slider frame 15, due to the sliding The rods 16 are arranged at a horizontal interval, so that the sliding seat 17 generates a yaw moment with respect to the sliding rod frame 15 due to the load of the sawing arm 14 and the sliding rods 16, which easily causes the sawing arm 14 to swing up and down, affecting the sawing. The precision of the cutting, in addition, because the stability of the saw arm 14 is not good, it is easy to generate a large vibration during sawing and affect the service life of the machine.

2. Since the carriage 17 is supported by the base 12 by the slide frame 15, in order to maintain the structural strength to support the weight of the saw arm 14 and the slide bars 16, the slide frame 15 is provided for the sliding The structural thickness of the rod 16 sleeve is bound to increase, and at the same time, in order to maintain a certain size of the sawing stroke, the length of the structure of the slider frame 15 for the sleeves 16 is bound to increase, so the length of the sliders 16 must also be lengthened. Increase the overall cost.

3. Since the saw arm 14 is disposed at the front end of the sliding seat 17, when the sawing work is to be performed, the rear side of the base 12 needs to reserve a space for sliding the sliding seat 17 for operation, and a relatively large working space is required. When storing or transporting, a large space is also required. Therefore, the conventional sawing machine has a large overall volume and has the disadvantage of occupying a field.

In this embodiment, the first sliding bar 32 is fixed to the supporting base 31 (see FIG. 10 ) at one end away from the sawing unit 4 , and opposite ends of the second sliding bar 33 are fixed to the support. Similarly, the first sliding bar 32 can also be fixed to the supporting base 31 with the structure of the second sliding bar 33. The sliding block 34 is on the first sliding bar 32 and the second sliding bar 3. Sexual sliding.

Referring to FIG. 9, a second plane F2 is defined by the axis of the first slider 32 and the axis of the second slider 33. The angle between the second plane F2 and the first plane F1 is greater than 0 degrees and less than 90 degrees.

With reference to FIG. 5, a third plane F3 is defined to pass through the rear side end of the first sliding bar 32 and is perpendicular to the first plane F1. Between the corresponding rear side end of the second sliding rod 33 and the third plane F3 A slider spacing d1 is formed. The sliding seat 34 has a first sleeve 341 connected to the first sliding rod 32 and a second sleeve 342 connected to the second sliding rod 33, and defines a fourth plane F4 through the first sleeve. The front end of the cylinder 341 is perpendicular to the first plane F1, and a sleeve spacing d2 is formed between the corresponding front side end of the second sleeve 342 and the fourth plane F4.

Referring to FIG. 5 , the sawing unit 4 is pivotally connected to the sliding block 34 and linearly movable relative to the working table 23 . The sliding seat 34 is located between the first sliding bar 32 and the second sliding bar 33 . The sawing unit 4 has a pivot axis X1 parallel to the fourth plane F4, a sawing axis X2 parallel to the pivot axis X1, and a saw blade 41 rotating about the sawing axis X2.

A pivotal distance d3 between the pivot axis X1 and the fourth plane F4 is less than the sleeve spacing d2, and the pivot axis X1 is higher than the second slider 33 and lower than the first slider 32. .

Referring to FIG. 5, FIG. 6, and FIG. 7, the sawing unit 4 is swingable relative to the table 23 between a lowest position and a highest position. In the lowest position, the sawing axis X2 is lower than the first The axis of the slide bar 32 itself and the axis of the second slide bar 33, in the highest position, the sawing axis X2 is higher than the axis of the first slide bar 32 and the axis of the second slide bar 33 itself.

During operation, a to-be-sawed object (not shown) is placed on the table 23, at which time the sawing unit 4 is located at the highest position, and the sawing unit 4 is first pushed along the first sliding bar 32 and the first After the two sliding rods 33 are moved to the appropriate positions, the sawing unit 4 is pressed down, the sawing unit 4 is swung to the lowest position and the object to be sawed is sawed (not shown), if the sawing width is reserved. When it is larger, the sawing unit 4 needs to be pushed. As shown in FIG. 6 and FIG. 7, the sawing unit 4 is moved along the first sliding bar 32 and the second sliding bar 33 when the lowest position is in the lower position. Complete the sawing action.

Through the above structural composition, the advantages and effects of the present invention can be summarized as follows:

1. The angle between the second plane F2 and the first plane F1 is greater than 0 degrees and less than 90 degrees to form a left-right difference between the first slider 32 and the second slider 33, plus The sliding rod spacing d1 forms a front-back difference between the first sliding rod 32 and the second sliding rod 33, so that the moment generated by the load of the sawing unit 4 is mutually pulled and balanced due to the aforementioned difference design, thereby improving The stability of the sawing unit 4, in addition to increasing the accuracy of the sawing, also reduces the vibration caused by the instability, thereby increasing the service life of the machine.

The pivot axis X1 of the present invention is higher than the second sliding bar 33 and lower than the first sliding bar 32. The sawing unit 4 is pivotally connected between the first sliding bar 32 and the second sliding bar 33. And the pivoting distance d3 is smaller than the sleeve spacing d2, so that the swaying yaw generated when the sawing unit 4 swings and performs the sawing action may act on the first sleeve 341 and the second sleeve. The force arms of the 342 are differently pulled and balanced with each other, and the stability of the sawing unit 4 is further increased.

3. The slider 34 of the present invention has the sleeve spacing d2 and the arrangement of the height difference, which increases the area of the sliding unit 34 supporting the sawing unit 4 compared to the conventional structure, thereby reducing the structure of the socket. The length of the first slider 32 and the second slider 33 are fixed to the support base 31, so that the length of the first slider 32 and the second slider 33 can be shorter than the length of the conventional slider. The same sliding sawing stroke that the sawing unit 4 still achieves.

4. The sawing unit 4 is pivotally connected between the first sliding bar 32 and the second sliding bar 33, and the moving unit 3 is located above the working table 23, the first sliding bar The second sliding bar 33 is fixed to the support base 31, so that the present invention can shorten the overall volume, and there is no need to leave a gap with the wall, so that the sawing unit 4 can be made by the first sliding bar 32 and One end of the second slide bar 33 adjacent to the front side 21 of the table 23 is moved to one end of the rear side 22 for operation, which has the advantage of not occupying the field.

In summary, the present invention utilizes the difference design of the first sliding bar 32 and the second sliding bar 33, and the matching of the sliding bar spacing d1 with the sleeve spacing d2 can not only increase the sawing unit. The stability of 4 increases the service life of the machine, and the overall volume is reduced, the working space and the storage space are saved, and the material cost is reduced, so that the object of the present invention can be achieved.

The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
