Detailed ways

As shown in FIG. 3 , FIG. 4 , and FIG. 5 , the band saw machine 20 with an angle adjustment structure of the present invention includes a base 21 , a saw band 22 , a driving structure 23 and an angle adjustment structure.

The base 21 has a notch 213 defined between the upper end portion 211 and the lower end portion 212 .

The driving structure 23 includes an upper transmission wheel 231, a lower transmission wheel 232, which is used for the saw band 22 to be sleeved and pivotally arranged on the upper and lower ends 211, 212 of the base 21, respectively, and the lower transmission wheel 232 can be driven forward and reverse and protrudes along the axial direction. out of the motor 233 .

The angle adjustment includes an adjustment seat 30 , a digital limiter 40 , a positioning member 50 and a saw table 60 .

The adjustment seat 30 is composed of a vertical plate 37 and a bottom panel 31 and a top panel 32 extending horizontally at the bottom and top of the vertical plate 37 . Four arc grooves 33 , 34 , 35 , 36 with the same axis 1A, the same radian and different radii are penetrating the vertical plate 37 along the axial direction.

The arc slot 33 is for the motor 233 of the driving structure 23 to pass through.

As shown in FIG. 5 , the limiting member 40 includes a bushing 41 , a guide rod 42 and a nut 43 .

The shaft sleeves 41 are respectively installed in the arc grooves 34 and 36 of the vertical plate 37 of the adjustment base 30 .

The guide rod 42 has a fixed end 421 passing through the sleeve 41 and screwed to the base 21 , and a threaded end 422 passing through the sleeve 41 and screwed with the nut 43 . The base 21 is limited on the adjustment seat 30 by the limiting member 40 .

As shown in Fig. 3, Fig. 5 and Fig. 6, the positioning member 50 includes a screw rod 51 which passes through the upper arc groove 35 of the vertical plate 37 of the adjustment seat 30 and is screwed to the base 21, a wrench 52 which is fixed and drives the screw rod 51 and is arranged on the The washer 53 between the wrench 52 and the adjustment seat 30 .

Thereby, the base 21 can be locked on the adjustment base 30 by turning the screw rod 51 with the wrench 52 , so that the base 21 can be positioned.

The saw table 60 is fixed on the top panel 32 of the adjustment seat 30 along the horizontal direction, and can allow the saw band 22 to pass through.

As shown in Fig. 6 and Fig. 7, when changing the cutting angle between the saw band 22 and the workpiece, it is only necessary to loosen the screw rod 51 with the wrench 52, so that the base 21 of the band saw machine 20 is opposite to each other with the axis 1A as the center of rotation. The adjustment seat 30 rotates, so that the motor 233, the bushing 41 of the two limiters 40 and the positioning member respectively pass through the four arc grooves 33, 34, 36, and 35 with the same axis 1A, the same radian and different radii. The screw rod 51 of 50 moves along the arc grooves 33, 34, 36, 35 with the same arc, so that the base 21 of the band saw machine 20 can drive the saw band 22 to tilt backward, and change the cutting angle between the saw band 22 and the workpiece. In this way, the workpiece can still be stably and fixedly placed on the saw table 60 in a horizontal state, and can be displaced smoothly.

As shown in FIGS. 8 and 9 , a rotator 70 may also be installed between the base 21 and the adjustment seat 30 .

The rotator 70 includes a positioning block 71 protruding from the adjusting base 30 along the axial direction, an actuating block 72 and an adjusting screw 73 pivotally mounted on the upper end 211 of the base 21 .

The positioning block 71 has a limiting groove 711 passing through along the radial direction and a shaft hole 712 along the axial direction.

The actuating block 72 is rotatably inserted into the shaft hole 712 of the positioning block 71 , and a limiting groove 711 and a screw hole 721 facing the positioning block 71 are formed thereon.

The adjusting screw 73 has a hand wheel 731 protruding from the upper end 211 of the base 21 and a threaded section 732 extending downward from the center of the hand wheel 731 and threaded in the screw hole 721 of the positioning block 72 .

When the operator rotates the hand wheel 731 of the adjusting screw 73 and drives the threaded section 732 to rotate, the adjusting screw 73 is in a state of self-rotation relative to the base 21. In the screw hole 721 of the positioning block 71, the moving block 72 is moved up and down along the threaded section 732 of the adjusting screw 73, but it is limited by the shaft hole 712 of the positioning block 71 and cannot move up and down, so that in the shaft hole 712 The rotational displacement makes the adjustment screw 73 radially displace and swing in the limiting groove 711, and then drives the base 21 to tilt backward along the radial direction, so as to achieve the purpose of changing the cutting angle. Moreover, the base 21 can be positioned by adjusting the threaded and position-limiting relationship between the screw rod 73 , the actuating block 72 and the positioning block 71 .

To sum up the above, the utility model has the following advantages and effects: when the base 21 of the band saw machine 20 is rotated relative to the adjustment seat 30 with the axis 1A as the center of rotation, the four bearings with the same axis are respectively placed The motor 233 in the arc grooves 33, 34, 36, and 35 of the heart 1A, the same radian and different radii, the axle sleeves 41 of the two limiters 40 and the screw rod 51 of the positioning element 50 are along the arc grooves 33, 34, 36, 35 and above. The same arc is moved so that the base 21 of the band saw machine 20 can drive the saw band 22 to tilt backward, changing the cutting angle between the saw band 22 and the workpiece. In this way, the workpiece can still be stably placed on the horizontal saw table 60 and can be moved smoothly, thereby improving the smoothness and safety of processing. Moreover, the inclination angle of the base 21 can be precisely adjusted by the setting of the rotator 70 , and the effects of labor saving and convenient adjustment can be achieved.
