It should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "setting" should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in this patent can be understood according to specific circumstances.

[0022] Reference Figure 1-Figure 3 A straightening and positioning device for a harvester steering drive shaft comprises a base 1, on which a straightener 6 is installed, a slide seat 3 is provided on the base 1, a connecting plate 5 is fixed to the slide seat 3 by bolts, and sliding openings 12 are provided near both ends of the connecting plate 5, and slide plates 10 are slidably connected in the two sliding openings 12, and a rotating shaft 19 is rotatably connected to the two slide plates 10, and a positioning component for the drive shaft is provided at one end of the rotating shaft 19, and a clamping component for fixing the drive shaft is also provided on the rotating shaft 19 to lock the drive shaft on the positioning component, and a locking component for keeping the rotating shaft 19 stable is provided on the slide plate 10, and after the drive shaft is fixed by the positioning component and the clamping component, the straightener 6 is started to straighten the drive shaft.

[0023] In the utility model, the positioning component is a conical sleeve 9, and one end of the two rotating shafts 19 is fixed with a conical sleeve 9 by bolts, so that the two ends of the transmission shaft are respectively placed in the conical sleeve 9, and the axis of the transmission shaft can be kept horizontal by the conical sleeve 9. A driving component for moving the two slides 10 is provided on the connecting plate 5, and the driving component is a bidirectional screw 11, which is rotatably connected to the bottom of the connecting plate 5, and the bidirectional screw 11 passes through the two slides 10 and is threadedly connected to the two slides 10. According to the length of the transmission shaft, the user rotates the bidirectional screw 11 to make the two slides 10 move toward each other along the sliding mouth 12 to adjust the distance between the two conical sleeves 9, so that the two ends of the transmission shaft are smoothly inserted into the conical sleeve 9, and the initial positioning of the transmission shaft is completed.

[0024] In the utility model, the engaging component is a magnet block 8, and the two rotating shafts 19 are both penetrated and fixedly connected with a fixing rod 17. The circumferential outer wall of the fixing rod 17 is slidably connected with two sliders 7. One end of the slider 7 is fixed with a magnet block 8 by a bolt, and an arc-shaped opening is opened at the bottom of the magnet block 8 to facilitate the clamping and adsorption of the transmission shaft. The circumferential outer wall of the fixing rod 17 is sleeved with two tension springs 18, and one end of the tension spring 18 is fixed to the fixing rod 17, and the other end is fixed to the corresponding slider 7. Move multiple sliders 7 outward, and the movement of the slider 7 causes each tension spring 18 to be stretched under force, and the two ends of the transmission shaft are respectively inserted into the conical sleeve 9, and the slider 7 is released. At this time, the tension spring 18 rebounds and resets to cause the slider 7 to reset in the opposite direction, and the slider 7 resets to cause the arc-shaped opening of the magnet block 8 to clamp and adsorb the surface of the transmission shaft, thereby fixing the transmission shaft in the conical sleeve 9.

[0025] In the utility model, the locking assembly includes a card strip 14 and a card slot 13. The circumferential outer wall at one end of the two rotating shafts 19 is provided with a plurality of card slots 13. A slide bar 16 is slidably connected to one side of the two slide plates 10. The bottom end of the slide bar 16 is fixed with a card strip 14 by a bolt, and the card strip 14 is carded with one of the card slots 13. The circumferential outer walls of the two slide bars 16 are sleeved with a spring 15, and the two ends of the spring 15 are respectively fixed to the slide bar 16 and the slide plate 10. The card strip 14 is disengaged from the card slot 13 by moving the two slide bars 16 upward, the spring 15 is contracted under force, and then the two rotating shafts 19 are rotated. Since the transmission shaft is locked in the conical sleeve 9, the transmission shaft is driven to rotate when the rotating shaft 19 rotates. After the side of the transmission shaft is changed, the slide bar 16 is released, and at this time, the spring 15 rebounds and resets to make the card strip 14 carded into one of the card slots 13 again, thereby locking the position of the rotating shaft 19.

[0026] In the utility model, a slide groove 2 is opened on the base 1, and the slide seat 3 is slidably connected in the slide groove 2. A screw rod 4 is rotatably connected to the base 1, and the screw rod 4 passes through the slide seat 3 and is threadedly connected to the slide seat 3. The screw rod 4 is rotated, and the screw rod 4 rotates to move the slide seat 3 to one side along the slide groove 2, so that the connecting plate 5 moves to one side as a whole, so as to adjust the lateral position of the transmission shaft, which is convenient for the straightening machine 6 to straighten each position of the transmission shaft.

[0027] Working principle: when the transmission shaft needs to be straightened, according to the length of the transmission shaft, the user first rotates the bidirectional screw 11 to make the two slide plates 10 move toward each other along the sliding mouth 12 to adjust the distance between the two conical sleeves 9, and then moves multiple sliders 7 to the outside respectively. The movement of the slider 7 causes each tension spring 18 to be stretched under force, and the two ends of the transmission shaft are respectively inserted into the conical sleeve 9, and the slider 7 is released. At this time, the tension spring 18 rebounds and resets to reset the slider 7 in the opposite direction, and the reset of the slider 7 causes the arc-shaped mouth of the magnet block 8 to engage and adsorb with the surface of the transmission shaft, thereby fixing the transmission shaft in the conical sleeve 9, and then starts the straightening machine 6 to straighten the transmission shaft, and then rotates the screw rod 4. The screw rod 4 rotates to make the slide seat 3 move to one side along the slide groove 2, and then the connecting plate 5 moves to one side as a whole to adjust the lateral position of the transmission shaft, so that the straightening machine 6 can align each position of the transmission shaft conveniently;

[0028] When it is necessary to straighten the other side of the transmission shaft, the user first moves the two slide bars 16 upward to disengage the clamping strip 14 from the clamping slot 13, and the spring 15 contracts under the force, and then rotates the two shafts 19. Since the transmission shaft is locked in the conical sleeve 9, the transmission shaft is driven to rotate when the shaft 19 rotates. After changing the side of the transmission shaft, the slide bar 16 is then released. At this time, the spring 15 rebounds and resets to make the clamping strip 14 re-enter one of the clamping slots 13, thereby locking the position of the shaft 19.
