[0003] In order to ensure the transmission accuracy and long-term stable operation of the rack guide rail in the agricultural machinery, the rack is usually permanently fixed with the guide rail support, the mounting base and other components through welding in the production process; the positioning accuracy before welding directly determines the installation position, flatness and meshing state of the guide rail with the gear, and then affects the assembly accuracy and operation quality of the whole machine.

When clamping, the locking pin 209 is inserted into the gap between the rack plate and the rack shaft, which cooperates with the limiting column on the clamping plate of the limiting motor 202 to ensure the longitudinal position of the rack plate on the rack shaft, and then the preliminary positioning and clamping are completed.

[0055] After the preliminary positioning and clamping are completed, the limiting motor 202 is reversed to reset, driving the clamping plate and the limiting column to separate from the contact with the rack guide rail 103, and the locking cylinder II 211 at both ends is started to drive the two locking clamps 219 to move towards the rack guide rail 103. The stepped clamps lock the locking frame strip I 207, the locking frame strip II 208 and the rack guide rail 103 (as shown in Figure 7 At the same time, the pushing cylinder 213 is started to drive the fastening shed 203 to deflect, so that the clamping strip of the fastening shed 203 is pressed on the protruding part of the rack plate (as shown in Figure 5After the first locking work is completed, the lifting cylinder 221 is started to drive the lifting seat 222 to lift, and then the rack guide rail 103 is lifted, so that the bottom of the rack guide rail 103 is flush with the bottom of the discharge plate 212 limiting groove. At this time, the middle height of the rack plate of the rack guide rail 103 is flush with the height of the pushing claw 217. When the fastening shed 203 is reset, the tensioning block 227 moves on the support frame 102, and then the tensioning rod on the tensioning block 227 moves, thereby tensioning the transmission belt 225, and ensuring the accuracy of the conveying assembly.

[0056] After the locking clamping is released, the transmission motor 224 is started to drive the transmission belt 225 to move, thereby driving the moving support 216 to move in the direction of the rack guide rail 103. When moving to the limiting top plate 226, the limiting top plate 226 presses the pushing block of the pushing claw 217, thereby driving the pushing claw 217 to move to the moving support 216, and then clamping into the gap of the rack plate of the rack guide rail 103 (as shown in FIG. 6). Figure 12The rack guide rail 103 is moved to the processing assembly 3 for cutting and polishing, and during the movement, the rack guide rail 103 is prevented from being dislocated by the limiting slots of the locking frame strip I 207 and the locking frame strip II 208 and the discharge plate 212. When the end surface of the rack guide rail 103 moves to the extrusion plate 308, the extrusion plate 308 is moved to contact the signal triggering block 309. The signal triggering block 309 sends a signal, and the transmission motor 224 stops after receiving the signal, so that the movement of the rack guide rail 103 is paused. The rack guide rail 103 is cut by the processing assembly 3. After the cutting is completed, the rack guide rail 103 falls out. The extrusion plate 308 is separated from the signal triggering block 309 under the action of the spring. The signal triggering block 309 sends a signal, and the transmission motor 224 is started again after receiving the signal, so that the rack guide rail 103 continues to move. The cutting work of the entire rack guide rail 103 is repeated until the last section of the rack guide rail 103 is completely moved out of the discharge plate 212. At this time, the limiting top plate 226 no longer presses the pushing block of the push pawl 217. The push pawl 217 is reset under the action of the spring, and the pushing of the rack guide rail 103 is released. The rack guide rail 103 falls out under the action of the processing assembly 3, and the welding and transfer work of the rack guide rail 103 are completed. During the conveying of the last section of the rack guide rail 103, the rack guide rail 103 is completely removed from the slot formed by the locking frame strip I 207 and the locking frame strip II 208. The material transfer machine 401 can be used for feeding work, and the preliminary positioning and clamping work is completed. The gap time is fully utilized, and the feeding time of the next rack guide rail 103 is shortened. After the conveying of the last section of the rack guide rail 103 is completed, the transmission motor 224 is reversed to reset the push pawl 217. After the reset, the locking work is completed, and the next welding and transfer work is repeated (the working of the push cylinder 213, the lifting cylinder 221, the locking cylinder I 210 and the locking cylinder II 211 is controlled and started by the pneumatic master valve 215 and the electromagnetic valve, respectively).

[0060] In operation, the cutting position of the cutting machine 302 is adjusted according to the length requirement of the rack guide 103, in the adjustment, the moving motor II 306 is started to drive the moving gantry 304 to move linearly on the mounting frame 303, the cutting length is determined by the cutting slot on the limiting plate I 307, and then the position of the cutting machine 302 is adjusted according to the cutting requirement, after the adjustment, the rack guide 103 is moved into the groove formed by the limiting plate I 307, the limiting plate II 312, the mounting frame 303 and the blanking rotary plate I 305 under the action of the welding clamping assembly 2, when the rack guide 103 is moved to the extrusion plate 308, the extrusion plate 308 is contacted with the signal triggering block 309, the signal triggering block 309 sends a signal to start the moving motor I 301 and the cutting machine 302, the moving motor I 301 is started to drive the cutting machine 302 to move downward, at the same time, the transmission rod 314 is rotated to drive the pushing carriage 315 to move to the direction of the deflection pushing rod I 316, the cutting machine 302 moves downward to cut the rack guide 103, in the cutting process, the rack guide 103 is limited by the groove formed by the limiting plate I 307, the limiting plate II 312 and the mounting frame 303, to ensure that the rack guide 103 will not be dislocated to cause cutting deviation, in the cutting process, the pushing bar of the pushing carriage 315 pushes the deflection pushing rod I 316 to deflect, and then drives the blanking rotary plate I 305 to rotate around the shaft connected to the deflection pushing rod I 316, after the cutting is completed, the deflection of the deflection pushing rod I 316 reaches the maximum amplitude, at this time, the rack guide 103 falls out under the action of gravity, the extrusion plate 308 is reset, the signal triggering block 309 sends a signal, the moving motor I 301 is reversed to drive the cutting machine 302 and the pushing carriage 315 to reset, after the resetting is completed, the blanking rotary plate I 305 is reset under the action of the torsion spring, then the transmission motor 224 is rotated to continue to push the rack guide 103 into the processing assembly 3, and then the cutting work is completed.

[0061] The part of the rack guide rail 103 falling into the material receiving moving seat 317 starts the locking cylinder 325, and the pushing plate on the locking cylinder 325 drives the clamping of the rack guide rail 103. Before clamping, the connecting slider 324 moves linearly along the axis of the 325 under the action of the 325, thereby driving the extension end of the pushing telescopic cylinder II 323 to move towards the fixed end, so that the gas in the pushing telescopic cylinder II 323 is sent into the pushing telescopic cylinder I 322, thereby making the extension end of the pushing telescopic cylinder I 322 drive the pushing positioning strip I 320 and the pushing positioning strip II 321 to move towards the rack guide rail 103, thereby ensuring that the rack guide rail 103 is in the middle position. The pushing plate of the locking cylinder 325 pushes the rack guide rail 103 to be close to the material receiving moving seat 317, thereby ensuring the longitudinal polishing position of the rack guide rail 103. After positioning and clamping, the moving motor III 328 is started, thereby driving the rotating lead screw 327 to rotate, thereby driving the moving slider 326 to move. The moving slider 326 drives the material receiving moving seat 317 to move when moving, thereby driving the rack guide rail 103 to move. When the rack guide rail 103 moves under the vertical polisher 310, the moving motor III 328 stops rotating, and the vertical polisher 310 starts. The vertical polisher 310 is driven by the cylinder connected with the vertical polisher 310 to move downward, so that the polishing head is close to the welding position of the rack guide rail 103, thereby polishing the axial of the welding hole of the rack guide rail 103. After polishing, the vertical polisher 310 is reset under the action of the cylinder, and the moving motor III 328 continues to start, thereby driving the rack guide rail 103 to move. When moving, the transversely arranged transverse polisher 311 polishes the welding position of the rack guide rail 103 in the transverse direction. In the moving process, the trigger frame 318 pushes the deflection pushing rod II 330 to deflect, thereby making the material falling rotating plate II 329 deflect, so that the bottom of the rack guide rail 103 is no longer supported. After the transverse polisher 311 completes the transverse polishing of the rack guide rail 103, the locking cylinder 325 is reset, thereby making the pushing positioning strip I 320, the pushing positioning strip II 321 and the pushing plate of the locking cylinder 325 no longer fix the rack guide rail 103, thereby making the rack guide rail 103 fall into the subsequent processing assembly 5 under the action of gravity. After the rack guide rail 103 is discharged, the moving motor III 328 reverses to reset the material receiving moving seat 317, and the material falling rotating plate II 329 is reset under the action of the torsional spring, thereby polishing and deburring the next section of the rack guide rail 103. The welding slag, oil stains and other impurities generated in the welding, cutting, polishing and deburring processes of the rack guide rail 103 are cleaned by the subsequent processing assembly 5. Appropriate chemical cleaning agent or ultrasonic equipment is used to ensure that the product surface is free of residual impurities, which is beneficial to subsequent corrosion prevention treatment. The cleaned product enters the hot galvanizing process, is immersed in high-temperature zinc liquid, and a dense zinc layer is formed on the surface of the product, thereby improving the corrosion resistance of the product and enhancing the service life and appearance quality of the overall product, thereby completing the machining work of the rack guide rail 103.
