When this novel high accuracy desk-top carpenter's sawing machine of needs uses, its theory of operation is as follows:

positioning and material blocking processes:

first, the user needs to fix the laser emitter 203 for positioning inside the corresponding frame 206 by bolts, and then to activate the laser emitter 203 to emit a horizontal laser beam, which leaves a horizontal line on the upper surface of the processing platform 1, because the center of the laser beam of the laser emitter 203 and the front side surface of the striker push plate 304 are in the same plane, the horizontal line position of the laser beam therefore represents the front end surface position of the striker push plate 304, then the material blocking push plate 304 and the positioning push plate 301 can move back and forth under the control of the material blocking cylinder 305 and the positioning cylinder 204 until the horizontal line of the laser beam moves to the position of the specific scale block 202 and then stops, so that the position fixation of the material blocking push plate 304 is realized, the traditional mode of directly observing the scale is replaced by the matching of the laser beam and the scale block 202, the problem that direct observation scales lead to less intuition and are easy to cause errors of observation angles can be avoided.

The sawmilling process comprises the following steps:

after positioning and material blocking are completed, a user can independently control the positioning air cylinder 204, so that the positioning air rod 205 inside the positioning air cylinder 204 can drive the positioning push plate 301 to move backwards, the positioning push plate 301 can drive the laser emitter 203 to move backwards through the vertical plate 306 and the frame 206, the front side part of the material blocking push plate 304 is vacated, the transverse movement of the wood plate on the front side of the material blocking push plate 304 is not blocked by the positions of the laser emitters 203 on two sides, the positioning air cylinder 204 is controlled to drive the laser emitter 203 to reset when the position of the material blocking push plate 304 is adjusted next time, the problem of inconvenient use caused by the fact that the laser emitter 203 needs to be positioned by hands usually when positioning is avoided, the user can start the motor 502 later, the output shaft of the motor 502 can drive the driving shaft 507 to rotate through the belt 501 and the belt pulley 503, and then the driving shaft 507 can drive the driven shaft 506 to rotate through the driving gear 508 and the driven gear 505, the driven shaft 506 can drive the saw blade 6 to rotate at a high speed, then a user can place the wood board on the upper surface of the processing platform 1, one side of the rear part of the wood board is attached to the material blocking push plate 304, finally, the wood board moves from the right side to the left side of the front part of the material blocking push plate 304, the front and back size of the cutting part and the matching reading of the laser beam and the scale block 202 are consistent, and the wood board moves from right to left above the processing platform 1 in the process of matching the saw blade 6 rotating at a high speed to cut off the specific size part of the wood board.

The inclined sawing process comprises the following steps:

in the wood sawing process, in order to process a wood-sawing bevel at a specific angle, the saw blade 6 generally needs to be tilted, and then the wood board is moved from one side to the other side to implement the bevel wood-sawing process at the specific angle, but in the prior art, the saw blade 6 is usually directly rotated to implement the adjustment, but because the reference axis of the rotation has a certain distance from the upper edge positions of the saw blade 6 and the processing platform 1, the upper edge position of the saw blade 6 and the processing platform 1 is convenient to change after the saw blade 6 rotates, and the reading of the scale 202 cannot be equal to the cutting size of the bottom of the wood board, therefore, when the saw blade 6 is tilted, a user can firstly control the rotating cylinder 10 to enable the rotating air rod 17 to drive the central circular rod 407 to move through the base 18, so that the central circular rod 407 can drive the end plate 403 and the saw blade 6 to rotate around the pin shaft at the rotating support 19, the saw blade 6 and the end plate 403 can rotate to a specific required angle, the angle range of the scheme is between 0 degree and 45 degrees, the upper edge positions of the oblique cutting saw blade 6 and the processing platform 1 and the original position (namely the bottom cutting point of the contact between the saw blade 6 and the wood board, hereinafter referred to as the bottom cutting point) generate a size deviation, at the moment, a user can control the lifting cylinder 9, the lifting air rod 15 can push the groove plate 13 to move upwards, the extending length of the rotating air rod 17 is constant in the lifting process, so that the inclination angle of the saw blade 6 cannot be changed all the time, the groove plate 13 can push the end plate 403 and the saw blade 6 to move upwards, the sliding block 20 slides in the sleeve plate 11, the height distance between the axis of the pin shaft at the rotating support 19 and the upper edge positions of the saw blade 6 and the processing platform 1 is simultaneously compensated, the position of the oblique cutting saw blade 6 can be lifted, and the position of the bottom cutting point of the oblique cutting saw blade 6 is adjusted and reset, the scale 202 can be adjusted and reset to be equal to the cutting size of the bottom of the wood board after reading, the problem that the original material blocking structure cannot accurately determine the accurate processing position of the bottom of the wood board due to the change of the position of the cutting point of the bottom of the saw blade 6 after inclining is avoided, meanwhile, due to the sliding fit of the three round rods 407 and the groove plates 13, the inner walls of the groove plates 13 with any angle within the range of 45 degrees and the outer walls of the three round rods 407 are both kept attached to each other no matter the round rods 407 rotate to any angle, at the moment, no matter the saw blade 6 and the round rods 407 rotate to any angle, the groove plates 13 can be lifted and lowered by driving the three round rods 407, the end plates 403 and the saw blade 6 through the inner walls, the saw blade 6 can be rotated at any angle, the height distance between the axis of the pin shaft at the rotating support 19 and the upper edge positions of the saw blade 6 and the processing platform 1 can be supplemented, and the problem that the adjustment and resetting of the bottom cutting point after the saw blade 6 rotates cannot be conveniently realized at any angle is solved.
