[0032] like Figure 1-11 As shown, the processing machine is described in detail:

[0033] A processing machine tool comprises a platform plate 101 and a side seat 103. The side of the platform plate 101 is provided with the side seat 103. The upper end of the side seat 103 is provided with a fixed shaft 104. A turntable 201 rotates on the fixed shaft 104. A door-shaped frame 202 is fixed on the turntable 201. A limit block 204 is connected inside the door-shaped frame 202. It also comprises an arm plate 301. An inner long hole 302 is provided in the middle of the arm plate 301. The arm plate 301 is slidably mounted on the limit block 204 through the inner long hole 302. A power shaft 304 rotates at one end of the arm plate 301. A coaxial limit sliding sleeve 401 is provided on the power shaft 304. A grinding wheel disc 402 is fixed to the lower end of the sleeve 401. A spring I 403 is provided between the grinding wheel disc 402 and the power shaft 304.

[0034] When in use, the flat plate to be polished is placed on the platform plate 101, and then the support arm plate 301 is controlled to drive the door frame 202, so that the turntable 201 rotates on the fixed shaft 104, thereby moving the polishing wheel 402 to the flat plate to be polished, and pulling up the polishing wheel 402, so that the polishing wheel 402 overcomes the elastic force of the spring I 403, and the sleeve 401 slides on the power shaft 304, and then the polishing wheel 402 is pressed against the polishing surface of the flat plate to be polished, and then the power motor installed on the support arm plate 301 is started to transmit the power shaft 304, and then the polishing wheel 402 is driven to rotate through the sleeve 401, thereby polishing the polishing surface of the flat plate to be polished.

[0035] Moreover, the turntable 201 rotates on the fixed shaft 104, so that the arm plate 301 drives the grinding wheel 402 to reciprocate around the fixed shaft 104, thereby grinding a large area of ​​the grinding surface of the plate to be ground.

[0036] Moreover, since the arm plate 301 can slide on the limit block 204 through the inner long hole 302, the swing radius can be changed, thereby further increasing the grinding range.

[0037] Further:

[0038] Grooves 303 are provided on both sides of the inner long hole 302, and racks 501 are provided in the two grooves 303 for limiting sliding. Springs II 502 are provided between the two racks 501 and the inner walls of the grooves 303 respectively, so that the racks 501 press against the limit block 204, so that the limit block 204 and the support arm plate 301 are relatively fixed.

[0039] The end of the support arm plate 301 away from the power shaft 304 is fixed with a shroud 305 , and a T-shaped block 503 is slidably passed through the shroud 305 , pushing the T-shaped block 503 to press against the two racks 501 , so that the two racks 501 are separated from the limit block 204 at the same time.

[0040] A spring III 504 is provided between the T-shaped block 503 and the enclosure plate 305 .

[0041] The two racks 501 are both provided with beveled ends near the T-shaped block 503 .

[0042] The elastic force of spring II 502 will push the rack 501 toward the limit block 204, so that the tooth tips and tooth grooves on the rack 501 cooperate with the tooth tips and tooth grooves on the side of the limit block 204 to form a relative limit between the two. At the same time, the relative limit between the rack 501 and the support arm plate 301 forms a relative limit between the support arm plate 301 and the limit block 204.

[0043] When the radius of the reciprocating swing of the grinding wheel 402 needs to be changed, the T-shaped block 503 is pushed to squeeze the inclined surface end of the rack 501, and then the two racks 501 are pressed tightly, so that the two racks 501 are separated from the limit block 204 at the same time. At this time, the support arm plate 301 can be moved on the limit block 204 to achieve the purpose of changing the swing radius;

[0044] Among them, through spring III 504, after the T-shaped block 503 is released, the T-shaped block 503 can automatically return, and then the two racks 501 are pressed against the limit block 204 again through the elastic force of spring II 502, forming a relative limit between the support arm plate 301 and the limit block 204 again.

[0045] Further:

[0046] An adjusting screw 203 is rotatably mounted on the door-shaped frame 202 , and the adjusting screw 203 is threadedly connected to a limiting block 204 .

[0047] By rotating the adjusting screw 203, the limit block 204 can be raised or lowered in the door frame 202, and then the grinding wheel 402 can be raised or lowered to adapt to the grinding of plates of different thicknesses; at the same time, the grinding force can be adjusted in conjunction with the spring I 403.

[0048] like Figure 10-11 As shown:

[0049] The platform plate 101 is provided with a plurality of through holes 102 , each through hole 102 has a sliding post 602 sliding in it, each sliding post 602 has a screw head 601 at the lower end, and each screw head 601 is threadedly connected to the platform plate 101 .

[0050] In order to prevent the flat plate from sliding on the platform plate 101 during grinding, the screw head 601 can be rotated so that the slide column 602 protrudes from the platform plate 101 and limits the edge position of the flat plate. Thus, through the cooperation of multiple slide columns 602, the flat plate is prevented from sliding during grinding, and the positioning of flat plates of any shape can be adapted.

[0051] Further:

[0052] The side seat 103 is threadedly connected with a clamping screw 604 , and the clamping screw 604 is rotated with a top plate 603 near the end of the platform plate 101 .

[0053] Since the position of the slide column 602 is fixed, after the plurality of slide columns 602 protrude from the platform plate 101 for limiting, the plate may still slide slightly, thereby rotating the clamping screw 604 so that the top plate 603 cooperates with the slide column 602 to press against the edge of the plate, thereby ensuring the fixation of the plate.

[0054] Further:

[0055] The top plate 603 is provided with a V-shaped opening at the end away from the clamping screw 604 .

[0056] The lower end of the top plate 603 slides in contact with the upper end surface of the platform plate 101 .
