In the present invention, another technical problem is also required to be solved, and according to specific process requirements, the workpiece 10 is also required to be subjected to chamfering treatment, that is, the two end faces of the cut small block 11 form inclined faces.

Referring to fig. 6 and 7, the following describes the specific structure of the cutting structure 44:

the cutter structure 44 includes a mounting block 100 and a cutter body 200 rotatably mounted on the mounting block 100. The installation fixing block 100 is provided with a rotation center hole 110, and the cutter body 200 is provided with a rotation shaft 210 matched with the rotation center hole 110.

Next, the method of adjusting the angle of the cutter structure 44 will be described.

The fastening screw 300 is unscrewed, and thus, the cutter body 200 is not pressed against the mounting fixing block 100 any more;

when the cutter body 200 is in a loose state, the cutter body 200 can be rotated to perform angle adjustment;

after the cutter body 200 is adjusted to a proper angle, the fastening screw 300 is tightened, and thus, the cutter body 200 can be fastened to the mounting block 100 by the fastening force of the fastening screw 300.

As shown in fig. 7, in the present embodiment, the number of the angle adjustment through holes 120 is two, and the two angle adjustment through holes 120 are distributed around the rotation center hole 110; the number of the fastening screws 300 is two, and the two fastening screws 300 respectively correspond to the two angle adjusting through holes 120; the number of the fastening screw holes 220 is two, and the two fastening screw holes 220 correspond to the two fastening screws 300, respectively. Such a structural design can make the stress more uniform, so that the cutter body 200 is more stably fastened to the mounting fixture 100.

Further, as shown in fig. 7, the cutter structure 44 further includes a blade 400, the blade 400 being detachably mounted to the cutter body 200 by a set screw 410. In the repeated cutting process, the sharp edge of the blade 400 is sharpened, so that the blade 400 needs to be replaced, and the blade 400 is detachably mounted on the cutter body 200 by the set screw 410, which is very convenient.

In this embodiment, the cutting apparatus 20 with an adjustable angle of the cutter further includes an electric box 21 (as shown in fig. 3), the electric box 21 is disposed on a side of the base 30, and the electric box 21 is used for providing power for the driving mechanism a.

In this embodiment, the cutting apparatus 20 with the adjustable angle of the cutter further includes an illumination bracket 22 (as shown in fig. 3), and the illumination bracket 22 is mounted on the base 30.

In the present embodiment, an LED illumination lamp (not shown) is provided on the illumination bracket 22.

The cutting apparatus 20 with adjustable angle of the cutting blade of the present invention further comprises a safety driving device 70 (as shown in fig. 3) mounted on the base 30, wherein the safety driving device 70 is electrically connected with the driving mechanism. By providing the safety drive device 70, the drive mechanism can be controlled more safely, and the drive mechanism can be prevented from being triggered by mistake.

As shown in fig. 8, specifically, the safety drive apparatus 70 includes: a fixed seat 500, a sliding rocker 600, and two buttons 700.

The fixing base 500 is fixed on the table surface 31 of the base 30.

Referring to fig. 8 and 9, the fixing base 500 has a receiving cavity 510, and the sliding rocker 600 is received in the receiving cavity 510; the bottom of the accommodating cavity 510 is provided with a sliding guide groove 511, the middle part of the sliding type seesaw 600 is provided with a sliding guide block 610, and the sliding type seesaw 600 is rotatably and slidably arranged in the sliding guide groove 511 through the sliding guide block 610; a return spring 800 is further disposed in the accommodating cavity 510, and the return spring 800 is used for enabling the sliding rocker 600 to slide along the sliding guide groove 511 for return. Here, it is to be explained that the sliding-type rocker 600 is rotatably and slidably provided in the sliding guide groove 511 by the sliding guide block 610, and it should be understood that the sliding-type rocker 600 may be formed in a "see-saw" motion in which one end of the sliding-type rocker 600 is lowered and the other end is raised during rotation; the "slidable" should be understood that the sliding rocker 600 is linearly reciprocated along the grooved direction of the sliding guide groove 511.

As shown in fig. 9, the bottom of the accommodating cavity 510 is further provided with two blocking grooves 512, the two blocking grooves 512 are respectively located at two sides of the sliding guide groove 511, and two ends of the sliding rocker 600 respectively form blocking protrusions 620 matched with the two blocking grooves 512.

Referring to fig. 8 and 9, two buttons 700 are disposed on the fixing base 500 and outside the accommodating cavity 510, and the two buttons 700 respectively correspond to the blocking protrusions 620 at two ends of the sliding rocker 600; the blocking protrusion 620 has an inclined surface 621, and the button 700 has a telescopic rod 710, and the telescopic rod 710 is inserted into the wall of the accommodating cavity 510 and is pressed against the inclined surface 621 of the blocking protrusion 620 by the telescopic spring 720.

The sliding rocker 600 is provided with a trigger lever 810 (as shown in fig. 9), and the driving mechanism has a contact point, and the trigger lever 810 is contacted with or separated from the contact point.

Next, a method of using the safety driving device 70 and an operation principle thereof will be described.

In the original state, the trigger lever 810 is separated from the contact of the driving mechanism, and in the separated state, the driving mechanism is not triggered to be driven, so that the device does not work;

to bring the trigger lever 810 into contact with the contacts of the driving mechanism, the left and right hands of the operator need to simultaneously press the two buttons 700, respectively; when two buttons 700 are pressed simultaneously, the two ends of the sliding rocker 600 do not move as a high-low "seesaw" due to the balance of the stress; because the blocking protrusion 620 has an inclined surface 621, during the pressing of the button 700, the button 700 pushes the sliding rocker 600 to slide along the sliding guide groove 511 through the inclined surface 621, and the sliding rocker 600 further drives the trigger lever 810 thereon to move, so that the trigger lever 810 can contact with the contact of the driving mechanism, and the contact is touched by the trigger lever 810 to switch on the circuit of the driving mechanism, so that the driving mechanism can drive the lifting moving plate 42 and the cutting assembly 43 to press down to divide the workpiece 10;

canceling the pressing action of the two buttons 700, the sliding rocker 600 will reset under the action of the reset spring 800, so that the trigger lever 810 is separated from the contact of the driving mechanism, the piston of the driving mechanism with the cylinder structure will reset under the action of the built-in spring, and the driving mechanism drives the lifting moving plate 42 and the cutting assembly 43 to lift and separate from the workpiece 10;

as shown in fig. 10, if two buttons 700 are not pressed simultaneously, both ends of the sliding type rocker 600 undergo a high-low "seesaw" motion due to unbalanced force, when the sliding type rocker 600 undergoes the "seesaw" motion, one of the blocking protrusions 620 of the sliding type rocker 600 is caught in the corresponding blocking groove 512, the blocking groove 512 blocks the sliding type rocker 600 by the blocking protrusion 620, and thus the trigger lever 810 cannot contact with the contact of the driving mechanism;

it can be seen that the design can improve the safety of the production, and the operator needs to press the two buttons 700 simultaneously to start the driving mechanism, and at this time, the operator's hands are completely separated from the workpiece 10, so as to prevent the operator's hands from being cut by the cutter structure 44, thereby greatly improving the safety of the production.

Here, in the present invention, the telescopic rod 710 is inserted into the wall of the accommodating chamber 510 and is pressed against the inclined surface 621 of the blocking boss 620 by the telescopic spring 720 (as shown in fig. 11), and the telescopic spring 720 has two functions: on the one hand, the telescopic spring 720 provides an elastic restoring force to the telescopic link 710, and on the other hand, the telescopic spring 720 applies an indirect elastic force to the inclined surface 621 of the blocking boss 620 through the telescopic link 710, so that the sliding rocker 600 is kept balanced against an external force.

In order to further improve the production safety, the safety driving device 70 of the present invention further includes an anti-false touch knob 900 (as shown in fig. 9), the anti-false touch knob 900 is rotatably disposed on the fixing seat 500, the anti-false touch knob 900 is a hollow cavity structure with two hollow ends, and the button 700 is sleeved in the hollow cavity of the anti-false touch knob 900.

As shown in fig. 11, in addition, a blocking ring 910 is disposed in the hollow cavity of the anti-false touch knob 900, a blocking rod 730 is disposed on the outer side wall of the button 700, and an unlocking through hole 911 for avoiding the blocking rod 730 is formed on the blocking ring 910. The anti-false touch knob 900 is shown in a cut-away state so that the internal structure of the anti-false touch knob 900 can be clearly displayed.

By providing the anti-false touch knob 900, the button 700 can be protected from both aspects, preventing the button 700 from being touched by false:

in the first aspect, the anti-false touch knob 900 is a hollow cavity structure with two hollow ends, the button 700 is sleeved in the hollow cavity of the anti-false touch knob 900, and the structure design is such that the button 700 is completely wrapped in the hollow cavity of the anti-false touch knob 900, an operator can only press the button 700 at an opening end of the anti-false touch knob 900 by fingers, and if the operation is not performed, the pressing operation of the button 700 cannot be realized;

on the other hand, the anti-false touch knob 900 can be rotated, and when the unlocking through hole 911 on the blocking ring 910 does not correspond to the blocking rod 730, the blocking rod 730 is blocked by the blocking ring 910, so that the button 700 cannot be pressed down; only when the anti-false knob 900 is rotated so that the unlocking through hole 911 of the blocking ring 910 corresponds to the blocking lever 730, the blocking lever 730 smoothly passes through the unlocking through hole 911, and the button 700 is pressed down.

To further enhance the safety of the production, the safety drive 70 of the present invention further includes a built-in lock mechanism 1000 (shown in fig. 8). It should be noted that, the built-in lock mechanism 1000 is not used in normal situations, and is considered for use only in special situations, for example, when an operator leaves a station for a long time, the operator is prevented from operating the device by an external person.

Referring to fig. 9, 12 and 13, specifically, the built-in lock mechanism 1000 includes: built-in lock knob 1110, built-in lock dial 1120, built-in lock lever 1130.

The fixing base 500 is provided with a hidden groove 520 (as shown in fig. 9), the center of the built-in lock turntable 1120 is transferred and arranged in the hidden groove 520, and the middle part of the built-in lock lever 1130 is transferred and arranged in the hidden groove 520.

The combination lock knob 1110 is located outside the hidden slot 520 and is coupled to the combination lock dial 1120.

An unlocking notch 1121 is formed at the edge of the built-in lock turntable 1120, and a locking tooth slot 920 is formed on the outer side wall of the anti-false touch knob 900.

One end of the built-in lock lever 1130 is pressed against the edge of the built-in lock turntable 1120, and the other end is pressed against the locking tooth slot 920 (shown in fig. 9) of the anti-false knob 900; alternatively, one end of the built-in lock lever 1130 is received in the unlocking notch 1121 of the built-in lock dial 1120, and the other end is disengaged from the locking tooth groove 920 of the anti-false knob 900.

Next, a method for using the built-in lock mechanism 1000 and an operation principle thereof will be described:

as shown in fig. 12, when the operator leaves the operation station for a long time, the built-in lock mechanism 1000 needs to be opened, and the opening method is as follows: rotating the built-in lock knob 1110, the built-in lock knob 1110 further drives the built-in lock turntable 1120 to rotate, so that one end of the built-in lock lever 1130 is pressed on the edge of the built-in lock turntable 1120, then the other end of the built-in lock lever 1130 is sunk into the locking tooth socket 920 of the anti-false touch knob 900, the locking tooth socket 920 is clamped by the built-in lock lever 1130, then the anti-false touch knob 900 cannot be rotated at will, and the blocking rod 730 on the button 700 is blocked by the blocking ring 910 at the moment, so that the button 700 is fully ensured not to be pressed at will, and the use safety is improved;

as shown in fig. 13, when the operator returns to the operating station again, the built-in lock mechanism 1000 needs to be closed, and the closing method is as follows: when the built-in lock knob 1110 is rotated in the opposite direction, the built-in lock knob 1110 drives the built-in lock turntable 1120 to rotate in the opposite direction, and when the unlocking notch 1121 of the built-in lock turntable 1120 reaches a designated position, the unlocking notch 1121 corresponds to one end of the built-in lock lever 1130, at this time, the anti-false touch knob 900 can be rotated, a rotating force is slightly applied to the anti-false touch knob 900, one end of the built-in lock lever 1130 is sprung out from the locking tooth slot 920, the other end of the built-in lock lever 1130 is sunk into the unlocking notch 1121, and the unlocking notch 1121 provides a space for avoiding the rotation of the built-in lock lever 1130.

As shown in fig. 9, it is to be specifically noted that in the present invention, only one set of built-in lock mechanisms 1000 is required to control one of the anti-false touch knobs 900, and two anti-false touch knobs 900 are not required to be simultaneously controlled, so that the arrangement of the mechanisms is simplified. The explanation is as follows: when one of the anti-false touch knobs 900 is controlled using the set of built-in lock mechanisms 1000, even if the button 700 in the other anti-false touch knob 900 is pressed, since the sliding rocker 600 moves in a "see-saw" manner, one of the blocking protrusions 620 of the sliding rocker 600 is caught in the corresponding blocking groove 512, thereby preventing the sliding rocker 600 from sliding.

The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
