[0032] The adjusting and pressing mechanism 5 includes a first adjusting motor 52 and a moving block 59. The first adjusting motor 52 is fixedly installed on the outer surface of the mounting turntable 4. One end of the output shaft of the first adjusting motor 52 is fixedly installed with an adjusting screw rod 53. One end of the adjusting screw rod 53 extends to the inside of the stroke groove 9.

[0034] The specific implementation method is as follows: When clamping a workpiece, pull up the moving shell 54, place the workpiece under different pressing components 56. At this time, turn on the second adjusting motor 561 to drive the pressing component 56 to rotate, so that the directions of the two positioning rollers 564 at the bottom of the mounting cover 563 are parallel to the installation direction of the workpiece. At this time, the workpiece can be directly pushed under each adjusting and pressing mechanism 5. The positioning rollers 564 play a role in pushing and installing the workpiece. After the workpiece is installed, according to the cutting progress direction of the workpiece, turn on the second adjusting motor 561 again to drive the pressing component 56 to rotate, so that the positioning rollers 564 are adjusted to a position perpendicular to the cutting progress direction of the workpiece. At this time, multiple positioning rollers 564 can firmly fix the workpiece to avoid displacement during cutting. At this time, turn on the adjusting motor 1 to control the displacement of the overall structure. After cutting, make the direction of the positioning rollers 564 return to a position parallel to the installation direction of the workpiece again. At this time, the cut workpiece can be directly and quickly slid out.

[0035] Through this design, the traditional hydraulic workpiece positioning design is abandoned. By using multiple different positioning rollers and changing the directions of the positioning rollers, rapid positioning of the cutting workpiece is achieved. Moreover, during the installation and disassembly of the cutting workpiece, the convenience of the operation is greatly improved. It can not only ensure the processing efficiency of the equipment, but also avoid the situation of workpiece damage or unstable positioning caused by hydraulic positioning, greatly improving the actual application effect of the device.

[0036] A number of positioning bumps 565 are provided on the outer surface of the positioning roller 564.

[0037] The specific implementation method is as follows: When positioning the workpiece, the position of the pressing component 56 can be adjusted according to the size of the workpiece, so that the pressing component 56 can be located directly above the workpiece. At the same time, the provided pressing spring 58 can enable the workpiece positioned by the pressing component 56 to have a certain buffer space, which can effectively avoid damage to the cutting saw when the workpiece comes into rigid contact with the cutting saw during the cutting process, and improve the actual application effect of the equipment.

[0038] The flow disturbing and cleaning component 8 includes a second mounting shaft 82. The second mounting shaft 82 is rotatably mounted at the bottom of the mounting turntable 4. The top end of the second mounting shaft 82 passes through and extends into the inner side of the base cover 32. A meshing gear 83 is fixedly mounted at the bottom end of the second mounting shaft 82. The meshing gear 83 is meshed and connected with the built-in gear meshing ring 35. A plurality of inclined flow disturbing plates 81 are fixedly mounted outside the upper part of the second mounting shaft 82. The plurality of inclined flow disturbing plates 81 are all located in the bottom cavity of the mounting turntable 4. The air flow hole 7 is communicated with the bottom cavity of the mounting turntable 4.

[0039] The specific implementation method is as follows: During the cutting process, if it is necessary to change the cutting position of the workpiece, directly control the mounting turntable 4 to rotate through the rotating motor 10, so as to change the position of the overall workpiece. During the rotation of the mounting turntable 4, the flow disturbing and cleaning component 8 can be driven to rotate synchronously. During the rotation process, the meshing gear 83 can continuously mesh with the built-in gear meshing ring 35 to rotate, and can drive the inclined flow disturbing plates 81 to rotate synchronously. The inclined flow disturbing plates 81 can generate wind force in the bottom cavity of the mounting turntable 4. Since the air flow hole 7 is communicated with the bottom cavity of the mounting turntable 4, finally the air flow can be discharged through the air flow hole 7 to synchronously clean the debris remaining on the workpiece during the previous cutting process.

[0040] Through this design, during the process of adjusting the position of the cutting workpiece, the synchronous cleaning of the debris on the workpiece can be realized, avoiding the influence of debris residue on subsequent cutting, and improving the application effect of the equipment.

[0041] Working principle: When clamping a workpiece, pull up the moving shell 54 to place the workpiece under different pressing components 56. At this time, turn on the second adjustment motor 561 to drive the pressing component 56 to rotate, so that the directions of the two positioning rollers 564 at the bottom of the mounting cover 563 are parallel to the mounting direction of the workpiece. At this time, the workpiece can be directly pushed under each adjustment pressing mechanism 5. The positioning rollers 564 play a role in pushing and installing the workpiece. After the workpiece is installed, according to the cutting direction of the workpiece, turn on the second adjustment motor 561 again to drive the pressing component 56 to rotate, so that the positioning rollers 564 are adjusted to a position perpendicular to the cutting direction of the workpiece. At this time, multiple positioning rollers 564 can firmly fix the workpiece to prevent displacement during cutting. At this time, turn on the adjustment motor 1 to control the displacement of the overall structure. After cutting, make the direction of the positioning rollers 564 return to a position parallel to the mounting direction of the workpiece again. At this time, the cut workpiece can be directly and quickly slid out for removal; When positioning the workpiece, the position of the pressing component 56 can be adjusted according to the size of the workpiece, so that the pressing component 56 can be directly above the workpiece. At the same time, the provided pressing spring 58 can make the workpiece positioned by the pressing component 56 have a certain buffer space, which can effectively prevent damage to the cutting saw when the workpiece is in rigid contact with the cutting saw during the cutting process, and improve the actual application effect of the equipment; During the cutting process, if it is necessary to change the cutting position of the workpiece, directly control the installation turntable 4 to rotate by rotating the motor 10, so as to change the position of the overall workpiece. During the rotation of the installation turntable 4, the turbulence cleaning component 8 can be synchronously driven to rotate. During the rotation process, the meshing gear 83 can continuously mesh with the built-in gear meshing ring 35 to rotate, which can synchronously drive the inclined turbulence plate 81 to rotate. The inclined turbulence plate 81 can generate wind force in the bottom cavity of the installation turntable 4. Since the air flow holes 7 are connected to the bottom cavity of the installation turntable 4, finally the air flow can be led out through the air flow holes 7 to synchronously clean the debris remaining on the workpiece during the previous cutting process.

[0042] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
