[0023] Example

[0024] like Figure 1 、 Figure 2 and Figure 3The illustrated embodiment of an adjustable distance high-precision cutting device for machining comprises a PLC controller 100, a horizontal bed 200, a feeding assembly 300, and a laser cutting assembly 400;

[0025] The feeding assembly 300 and the laser cutting assembly 400 are installed in a straight line on the horizontal bed 200.

[0026] The feeding assembly 300 and the laser cutting assembly 400 are respectively connected to the PLC controller 100 .

[0027] Working principle or structural principle: the feeding component 300 is used to clamp the cutting material and feed it horizontally to the working surface of the laser cutting component 400. The laser cutting component 400 is used to cut or trim the material fed by the feeding component 300. The PLC controller 100 is used to control the feeding component 300 and the laser cutting component 400 to perform coordinated feeding, cutting or trimming actions.

[0028] In this embodiment, the feeding assembly 300 preferably includes a horizontal support seat 3004 arranged parallel to one end face of the horizontal bed 200, and a motor seat 3001 arranged on one end face of the horizontal bed 200 and located on one side of the horizontal support seat 3004, and a servo motor 3002 arranged on the motor seat 3001, and a coupling 3003 arranged on the servo motor 3002, and a slide groove 3005 symmetrically arranged on one side of the horizontal support seat 3004, and a movable slider 3006 respectively located in the slide groove 3005, and a movable slider 3006 arranged at one end of the movable slider 3006. A movable seat 3007 with a screw hole on the end surface, a pneumatic clamp 3008 arranged on the movable seat 3007 with a screw hole, a screw rod 3013 that rotates through the movable seat 3007 with a screw hole and is connected to the coupling 3003 at one end, a plurality of first laser reflectors 3009 arranged in a straight line on the outer wall of the horizontal support seat 3004, and a first laser emitting unit 3010 arranged on the outer wall of the movable seat 3007 with a screw hole and matching the first laser reflectors 3009. The servo motor 3002 and the first laser emitting unit 3010 are respectively connected to the PLC controller 100;

[0029] In the above, the spacing between several first laser reflection parts 3009 (A / B / C / D / E / F / G, etc.) is different, which can complete the precise feeding when cutting or trimming different mold components cutting blanks. For example, A / B / C / D / E / F / G have different spacings, AB spacing, AC spacing, AD spacing, AE spacing, AF spacing, AG spacing. The control of different spacings meets the trimming or cutting of mold components cutting blanks of different sizes.

[0030] For example, when the blank of the mold component to be cut needs to be moved at an AB interval for processing (the first laser emitting unit 3010 moves to the first laser reflecting unit 3009 at position B), that is, when the control is realized, the blank of the mold component to be cut is aligned with the first laser reflecting unit 3009 at position A, first, the blank of the mold component to be cut is fixed by the pneumatic clamp 3008, and then the servo motor 3002 is controlled by the PLC controller 100 to start, and the screw rod 3013 is driven to rotate through the coupling 3003. The rotating screw rod 3013 drives the movable seat 3007 with a screw hole. Finally, when the first laser emitting unit 3010 on the movable seat 3007 with a screw hole is aligned with the first laser reflecting unit 3009 at position A, the PLC controller 100 controls the servo motor 3002 to stop through the signal fed back by the first laser emitting unit 3010. At this time, the blank of the mold component to be cut is located on the working surface of the laser cutting assembly 400, and the PLC controller 100 controls the laser cutting assembly 400 to start and perform the corresponding trimming or cutting action.

[0031] In this embodiment, preferably, the laser cutting assembly 400 includes an N-shaped frame 4001 provided on the other end face of the horizontal bed 200, and a cylinder seat 4002 provided on the N-shaped frame 4001, and a vertical control cylinder 4003 installed on the cylinder seat 4002, and a fixed seat 4004 provided at one end of the vertical control cylinder 4003, and a laser cutter 4005 installed on the fixed seat 4004, and a second laser reflecting portion 4008 provided on the inner wall of one side of the N-shaped frame 4001, and a horizontal plate 4006 provided on the fixed seat 4004, and a second laser emitting portion 4007 installed on the horizontal plate 4006 and matching with the second laser reflecting portion 4008, and the vertical control cylinder 4003, the laser cutter 4005, and the second laser emitting portion 4007 are respectively connected to the PLC controller 100;

[0032] In the above description, when the cut blank of the mold component to be cut is located on the working surface of the laser cutting assembly 400, the PLC controller 100 first controls the vertical control cylinder 4003 and the laser cutter 4005 to start, and then the laser cutter 4005 moves down to the corresponding position to perform modification or cutting, and finally the PLC controller 100 controls the vertical control cylinder 4003 to drive the laser cutter 4005 to reset;

[0033] The second laser emitting unit 4007 and the second laser reflecting unit 4008 realize the precise alignment function during the downward cutting control, thereby preventing the vertical control cylinder 4003 and the laser cutter 4005 from undergoing large displacement, which would affect the stability and accuracy of trimming or cutting.

[0034] In addition, preferably, several first laser reflection parts 3009 and first laser emission parts 3010 are respectively arranged on the outer walls of the horizontal support seat 3004 and the movable seat with screw holes 3007 on both sides. This can match the PLC controller 100 to achieve high stability and high precision horizontal feeding control on both sides, complete precise feeding spacing adjustment, and meet the processing and production of mold parts blanks of different sizes.

[0035] In addition, the feeding assembly 300 preferably further includes vertical rods 3011 provided on both sides of the outer wall of the movable seat 3007 with screw holes and located on both sides of the first laser emitting unit 3010, and brush plates 3012 provided at one end of the vertical rods 3011; wherein the brush plates 3012 are in sliding contact with the surface of the first laser emitting unit 3010;

[0036] The bristles of the above-mentioned brush plate 3012 are soft bristles, which are used to remove possible obstructions on the surface of the first laser emitting part 3010, realize real-time and unobstructed connection of the positioning signal, and complete precise control of different spacings.

[0037] In addition, the laser cutting assembly 400 preferably further includes a transparent cover 4009 disposed on the surface of the second laser reflecting portion 4008, and a transparent cover plate 4110 disposed on the end surface of the transparent cover 4009;

[0038] The transparent cover 4009 prevents the second laser reflector 4008 from being blocked by obstructions and thus prevents the alignment signal from being connected in a timely manner, thereby achieving precise alignment monitoring during the vertical reciprocating control of the cylinder 4003 and the laser cutter 4005 .

[0039] In addition, the transparent cover 4110 is preferably configured as an arc-shaped structure, so that obstructions on the surface of the transparent cover 4110 slide down in time and do not accumulate, and maintenance is performed before a single work process is completed to ensure that there is no obstruction of the alignment signal connection.

[0040] The cutting method (working principle) of the adjustable-distance high-precision cutting equipment for mechanical processing of the present invention includes the following steps: Step 1, the feeding component 300 clamps the cutting material to be cut and clamps it with the pneumatic clamp 3008; Step 2, the PLC controller 100 (different mold parts, input any different spacing between AG) controls the feeding component 300 to gradually feed the clamped cutting material horizontally to the working surface of the laser cutting component 400; Step 3, when the cutting material is horizontally fed to the working surface of the laser cutting component 400, the PLC controller 100 controls the feeding component 300 to stop, and the PLC controller 100 controls the laser cutting component 400 to start cutting or trimming the cutting material on the working surface; Step 4, the actions of Step 2 and Step 3 are performed reciprocally; Step 5, after the cutting or trimming of the cutting material is completed, the PLC controller 100 controls the feeding component 300 to reset.

[0041] The cutting method (working principle) of the adjustable-distance high-precision cutting equipment for mechanical processing of the present invention, another working feeding mode is to perform progressive AB / BC / CD / DE / EF / FG horizontal feeding in sequence.

In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or apparatus comprising the element.
