When the abrasive belt sander works, when the first clamping shaft 54 enters the left and right sides of the grid plate and the back end face of the grid plate is attached tightly, the T-shaped plate and the adjusting rod 513 are pulled to move upwards through the electric push rod 517, the adjusting rod 513 moves upwards to pull the left and right ear seats 53 on the upper side to move towards the grid plate, the ear seats 53 on the lower side move synchronously with the ear seats 53 on the upper side under the driving of the connecting rod 511, the first clamping shaft 54 moves upwards under the action of the contraction elastic force of the pulling spring 56 in the moving process of the ear seats 53, the tensioning function of the abrasive belt 501 is realized, the rotating roller 59 on the outer wall of the first clamping shaft 54 drives the abrasive belt 501 to be attached tightly to the left and right sides of the grid plate, and the abrasive belt 501 polishes the left and right sides of the grid plate conveniently.

Referring to fig. 6, a rectangular clamping groove 460 is formed in the front end surface of the fixed block 46, placing grooves 461 are formed in the left end surface and the right end surface of the rectangular clamping groove 460, a clamping plate 462 is installed on the rear end surface of the rectangular plate 50, the clamping plate 462 is composed of a triangular plate and a rectangular strip, the clamping plate 462 and the rectangular clamping groove 460 are connected in a sliding manner, a limiting plate 464 is installed in the placing groove 461 through a resisting spring 463, the resisting springs 463 are symmetrically arranged in a front-back manner, the limiting plate 464 is attached to the front end surface of the triangular plate, a pull rod 465 is installed on the end surface of the limiting plate 464, which is far away from the clamping plate 462, the pull rod 465 is located between the front-back resisting spring 463, a driving rod 466 is installed after the pull rod 465 penetrates through the fixed block 46, and when the length of the solid wood chair needing fine machining is short, the number of grating plates on the grating backrest 34 is also reduced, so that the redundant abrasive belt 501 can be disassembled, the redundant abrasive belt 501 can be disassembled in turn from the left side, drive pole 466 through pulling the fixed plate 45 left and right sides drives pull rod 465 to remove to both sides, pull rod 465 removes pulling limiting plate 464 and gets into in the standing groove 461, limiting plate 464 extrusion is supported tight spring 463 shrink this moment, then draw in board 462 with the card of rectangular plate 50 rear end face draws forward from rectangular slot 460 and takes out, T template 514 above mounting panel 51 slides out in following T type groove 519 simultaneously, so that unnecessary abrasive band 501 is polished to the grid plate, the problem that unnecessary abrasive band grid plate was polished has been avoided 501 to influence.

Referring to fig. 3, compensation belts 520 are installed at the upper end and the lower end of the abrasive belt 501, the compensation belts 520 are located on the abrasive belt 501 at the front end of the first clamp shaft 54, and the compensation belts polish partial grid plates blocked by the lug seats, so that the grid plates can be completely polished under the matching action of the compensation belts 520 and the abrasive belt 501, and the problem that the abrasive belt 501 cannot completely polish the two ends of the grid plates under the blocking action of the lug seats 53 is solved.

When the grid backrest fixing device works specifically, in the first step, the left end of the grid backrest 34 is clamped in the Contraband-type clamping plate 33 and the horizontal plate 30 on the left side, then the pull frame plate 330 pushes the Contraband-type clamping plate 33 on the right side to move leftwards, at the moment, the base plate 32 slides in the T-shaped sliding groove until the Contraband-type clamping plate 33 on the right side is clamped at the right end of the grid backrest 34, the left and right two Contraband-type clamping plates 33 clamp the grid backrest 34 tightly, then the threaded rod 38 is driven to rotate by rotating the chuck 39, the threaded rod 38 drives the arc-shaped clamping seat 37 to move downwards, meanwhile, the arc-shaped clamping seat 37 drives the limiting rod 36 to move towards the lower part of the limiting hole 35 until the U-shaped groove 370 at the lower end of the arc-shaped clamping seat 37 abuts against the upper end of the grid backrest 34, and at the moment, the grid backrest 34 is fixed under the action of the Contraband-type clamping plate 33 and the arc-shaped clamping seat 37.

And secondly, the support frame 42 is driven to move forwards through the electric sliding block 41, the support frame 42 moves forwards through the connecting plate 44, the fixing plate 45 and the fixing blocks 46 until the two first clamping shafts 54 in front of each fixing block 46 enter gaps on the left side and the right side of the grid plate on the grid backrest 34, when the first clamping shafts 54 enter the gaps on the left side and the right side of the grid plate, the abrasive belt 501 is tightly attached to the rear end surface of the grid plate under the pulling of the first clamping shafts 54, meanwhile, the abrasive belt 501 pulls the second clamping shafts 58 and drives the moving block 57 to move forwards, the moving block 57 moves to enable the pulling spring 56 to extend, at the moment, the second clamping shafts 58 play a tensioning role on the abrasive belt 501, and further, when the abrasive belt 501 is clamped on the left side and the right side of the grid plate by the two first clamping shafts 54 on the left side and the right side of the grid plate, the length of the abrasive belt 501 is enough to tightly attach and deform the grid plate.

Thirdly, the T-shaped plate and the adjusting rod 513 are pulled to move upwards through the electric push rod 517, the adjusting rod 513 moves upwards to pull the left and right ear seats 53 on the upper side to move towards the grating plate, at the moment, the ear seats 53 on the lower side move synchronously with the ear seats 53 on the upper side under the driving of the connecting rod 511, the first clamping shaft 54 moves upwards under the action of the contracting elastic force of the pulling spring 56 in the moving process of the ear seats 53, and therefore the tensioning function of the abrasive belt 501 is achieved, the rotating roller 59 on the outer wall of the first clamping shaft 54 drives the abrasive belt 501 to be attached to the left side and the right side of the grating, and the left side and the right side of the grating plate can be polished conveniently by the abrasive belt 501.

Fourthly, after the adjustment is completed, the air cylinder 43 is started, the air cylinder 43 drives the abrasive belt 501 to move up and down on the rear end face of the grating plate through the connecting plate 44, the fixing plate 45, the fixing block 46, the rectangular plate 50 and the bracket plate 51, and the abrasive belt 501 removes burrs on the rear end face of the grating plate.

Fifthly, when the length of the solid wood chair needing finish machining is short, the number of the grating plates on the grating backrest 34 is reduced, so that the redundant abrasive belt 501 can be disassembled, the redundant abrasive belt 501 is disassembled from the left side in sequence, the driving rods 466 on the left side and the right side of the fixing plate 45 are pulled to drive the pull rods 465 to move towards the two sides, the pull rods 465 move to pull the limiting plates 464 to enter the placing grooves 461, the limiting plates 464 extrude to abut against the springs 463 to contract, then the clamping plates 462 on the rear end face of the rectangular plate 50 are pulled forwards from the rectangular clamping grooves 460 to be taken out, and meanwhile the T-shaped plate 514 above the support plate 51 slides out of the T-shaped groove 519 so that the redundant abrasive belt 501 can polish the grating plates.
