[0002] The bar needs to be positioned when sawing on the sawing machine to prevent the bar from shaking during sawing, avoid the bar from damaging the saw and the sawing length and sawing surface of the bar from not meeting the requirements. At present, the common positioning method for the bar during sawing on the sawing machine is to press the bar with a pressing block. This positioning method has poor effect. The bar is easily shaken left and right during sawing by the saw. SUMMARY

[0003] In order to overcome the above-mentioned defects, the utility model provides a floating clamp positioning structure which can realize the clamping and positioning of the bar and avoid the bar from being shaken left and right during sawing on the sawing machine.

[0005] After the bar is loaded onto the sawing machine, the bar is conveyed between the two clamping plates, the driving piston cylinder is operated to push the two sliding seats to move towards each other, so that the two clamping plates clamp the bar left and right. Since the position of the bar is not necessarily in the middle of the two clamping plates, the clamping plate that first touches the bar will react the pushing force to the floating beam to drive the floating beam to move, so as to avoid the clamping plate from being blocked by the bar and avoid the bar from being damaged by the excessive pushing force. After the bar is completely clamped by the two clamping plates, the locking piston cylinder locks and positions the sliding seat to ensure the reliability of the clamping and positioning of the bar. Through this structure, the bar can be reliably clamped and positioned even if the loading position of the bar deviates, and the bar will not be damaged during clamping. Through the left and right clamping and positioning of the bar, the bar is prevented from being shaken left and right during sawing. After the bar is sawed, the driving piston cylinder drives the sliding seat to move reversely, so that the two clamping plates release the clamping and positioning of the bar, and then the bar can be conveyed.

[0032] The technical scheme of the utility model will be further specifically described below by specific embodiments and in combination with the drawings:

The locking piston cylinder 13 is connected with the other sliding seat 9; the driving piston cylinder 11 drives the two sliding seats 9 to move close to or away from each other.

In the initial state, the electromagnetic control valve is in the open state, the piston cavities on both sides of the piston are communicated through the medium pipeline, and at this time the piston can freely slide in the piston cavity.

[0035] During the movement of the sliding seat 9 driven by the driving piston cylinder 11, the electromagnetic control valve is opened, the two medium inlets and outlets are communicated, at this time the sliding seat 9 moves to pull the piston rod 15 to move, and the piston can move in the cylinder body 14. After the clamping plate 10 clamps the workpiece to the position, the electromagnetic control valve is closed, the two medium inlets and outlets are blocked, at this time the piston is limited in the cylinder body 14 and cannot move, thereby achieving the locking positioning of the piston rod 15, and also achieving the locking positioning of the sliding seat 9.

[0036] A floating slide rail 16 is mounted on the portal frame and is mounted on the bottom plate 5 of the fixed cross beam 2, the floating slide rail 16 is arranged in parallel with two roots, a floating cross beam 1 is mounted with a floating sliding block 17, and the floating sliding block 17 is slidingly fitted with the floating slide rail 16. The floating cross beam 1 and each floating slide rail 16 are correspondingly provided with three floating sliding blocks 17. V-shaped grooves are arranged on the opposite two side walls of the floating slide rail 16, and V-shaped protrusions are arranged on the floating sliding block 17, and the V-shaped protrusions are connected with the V-shaped grooves.

[0037] A linear guide rail 18 is mounted on the floating cross beam 1 and is mounted on the lower surface of the floating cross beam 1, the linear guide rail 18 is arranged in parallel with two roots, and a linear sliding block 19 is mounted on the sliding seat 9 and is slidingly fitted with the linear guide rail. The sliding seat 9 and each linear guide rail are correspondingly provided with two linear sliding blocks 19. V-shaped grooves are arranged on the opposite two side walls of the linear guide rail 18, and V-shaped protrusions are arranged on the linear sliding block 19, and the V-shaped protrusions are connected with the V-shaped grooves.

[0038] A rack 20 is arranged on the sliding seat 9, a gear 21 is mounted on the floating cross beam 1, and the gear 21 is meshingly driven between the two racks 20. The two racks 20 are arranged between the two linear guide rails, a limiting frame 22 is arranged at the middle position of the lower surface of the floating cross beam 1, the rack 20 is limited between the limiting frame 22 and the lower surface of the floating cross beam, and the gear 21 is rotationally connected with the limiting frame 22.

[0039] A fixed base 23 is mounted on the gantry, which is in turn mounted on the fixed crossbeam 2. A floating base 24 is mounted on the floating crossbeam 1. A brake locking mechanism is installed between the fixed base 23 and the floating base 24. The brake locking mechanism comprises a movable toothed plate 25 and a fixed toothed plate 26. Connecting blocks 27 are fastened between the upper and lower edges of the fixed toothed plate 26 and the fixed base 23. A gap is provided between the fixed toothed plate 26 and the fixed base 23. The movable toothed plate 25 is positioned between the fixed toothed plate 26 and the fixed base 23. The movable toothed plate 25 is connected to a brake piston cylinder 28, which is fastened to the floating base 24. The telescopic rod of the brake piston cylinder 28 is fixed to the movable toothed plate 25. The fixed toothed plate 26 has an elongated slot through which the telescopic rod of the brake piston cylinder 28 moves. The brake piston cylinder 28 drives the movable toothed plate 25 to move, bringing the movable toothed plate 25 and the fixed toothed plate 26 together, thereby braking and locking the floating crossbeam 1.

[0040] When the clamping plate 10 is clamping the bar, a gap remains between the movable toothed plate 25 and the fixed toothed plate 26, allowing the fixed seat 23 and the floating seat 24 to move relative to each other. After the clamping plate 10 has clamped the bar in place, the brake locking mechanism operates, and the brake piston cylinder 28 drives the movable toothed plate 25 to move, bringing the movable toothed plate 25 and the fixed toothed plate 26 together. The friction between the two provides the braking force, achieving the brake locking of the floating crossbeam 1.

[0041] After the bar is loaded onto the sawing machine, it is transported between the two clamping plates 10, driving the piston cylinder 11 to work, pushing the two slides 9 in a direction close to each other, so that the two clamping plates 10 clamp the bar left and right. Since the position where the bar is placed is not necessarily in the middle of the two clamping plates 10, the clamping plate 10 that touches the bar first receives the driving force and then reacts the driving force to the floating beam 1, driving the floating beam 1 to move, preventing the clamping plate 10 from being blocked by the bar and preventing excessive driving force from acting on the bar and causing damage to the bar. After the bar is completely clamped in place by the two clamping plates 10, the locking piston cylinder 13 locks the slide 9 to ensure the reliability of the clamping and positioning of the bar. Through this structural setting, even if the loading position of the bar deviates, the bar can be reliably clamped and positioned, and the bar will not be damaged during the clamping process. By clamping and positioning the bar left and right, the phenomenon of left and right shaking of the bar during sawing is avoided. After the bar material is sawn, the piston cylinder 11 is driven to drive the slide 9 to move in the opposite direction, so that the two clamping plates 10 remove the clamping and positioning of the bar material, and the bar material can be transported at this time.

After the bar is completely clamped in place by the two clamping plates 10, the locking piston cylinder 13 locks the slide 9 to ensure the reliability of the clamping and positioning of the bar. Through this structural setting, even if the loading position of the bar deviates, the bar can be reliably clamped and positioned, and the bar will not be damaged during the clamping process. By clamping and positioning the bar left and right, the phenomenon of left and right shaking of the bar during sawing is avoided. After the bar material is sawn, the piston cylinder 11 is driven to drive the slide 9 to move in the opposite direction, so that the two clamping plates 10 remove the clamping and positioning of the bar material, and the bar material can be transported at this time.
