[0021] A method for assembling an electric tractor, using the above-mentioned electric tractor assembly processing device to assemble the electric tractor, comprises the following steps:

[0022] S1, in the initial position of the support rod, the free end of the support rod is located outside and is perpendicular to the second linear moving member. At this time, driven by the lifting device, the detection roller contacts the end of the horizontal plate;

[0023] S2, the conveying assembly pushes the cross plate to perform linear motion in the horizontal direction, at which time the detection roller rolls relative to the assembly surface of the cross plate. If the assembly surface of the cross plate is uneven, the detection roller will change in height in the vertical direction. At this time, the detection roller pushes the support rod to change its position in the vertical direction. At this time, the support rod pushes the turntable to drive the cylinder to slide relative to the rotating rod. At this time, the pressure sensor is subjected to a change in the pressure of the pressing plate, that is, the technical effect of detecting the flatness of the assembly surface of the cross plate assembled and connected to the saddle can be achieved;

[0024] S3. If the inspection is qualified, the lifting device drives the Y-shaped bracket to move in the vertical direction, causing the inspection roller to move away from the horizontal plate, and the electric roller shaft drives the push plate to rotate, causing the free end of the push plate to move upward. At this time, the first motor drives the elliptical rectangular block to rotate at an angle of ninety degrees in the vertical direction. At this time, the elliptical rectangular block uses the elliptical rectangular groove to push and pull the push-pull plate, causing the push-pull plate to pull the plate body to slide along the first cavity. The first cavity pulls the push-pull rod to drive the electric roller shaft to move linearly. The electric roller shaft pulls the push plate to contact the connecting saddle on the support plate to limit the connecting saddle in the horizontal direction. At the same time, the pressing component can limit the connecting saddle in the vertical direction to achieve the technical effect of limiting the connecting saddle on the support plate;

[0025] S4, the second motor drives the rotating rod at the upper end to drive the end of the support rod connected to the detection roller to move in a circular motion, so that the two support rods face inward symmetrically, and at this time, the second linear motion member is started to pull the support rod to translate in the horizontal direction, so that the detection roller is inserted into the limit slide rail installed on the support rail and the detection roller is pressed against the inner wall of the limit slide rail, that is, the detection roller inserted into the limit slide rail is used to limit the elliptical rectangular block to prevent the elliptical rectangular block from shaking or deflecting, thereby reducing the pressure of the push plate on the connecting saddle and causing the connecting saddle to separate from the support plate when moving in the vertical direction. When the connecting saddle located at a high place is transported to a low place for assembly with the cross plate, if the movement speed is too fast, the risk of the connecting saddle colliding with the cross plate will increase, and because the movement speed of the connecting saddle in the vertical direction is proportional to the rotation speed of the detection roller, after the rotation speed of the detection roller exceeds the preset rotation speed threshold, the speed sensor starts the first linear motion member to pull the electric roller shaft to drive the push plate to contact the connecting saddle again, further limiting the connecting saddle to prevent the connecting saddle from separating from the support plate;

[0026] S5, after the assembly of the connecting saddle and the cross plate is completed and the welding is completed, the second linear motion member pushes the detection roller to disengage from the limiting slide rail and causes the detection roller to reset. At this time, the conveying component continues to push the cross plate, causing the assembled connecting saddle and the cross plate to disengage from the assembly position.

[0027] The present invention provides an electric tractor assembly processing device and a processing method thereof, which have the following beneficial effects compared with the prior art:

[0028] 1. The present invention can automatically assemble the cross plate and the connecting saddle, thereby reducing labor costs and increasing the assembly accuracy between the cross plate and the connecting saddle;

[0029] 2. In the present invention, in the initial position of the support rod, its free end is located on the outside and is perpendicular to the second linear motion part. At this time, driven by the lifting device, the detection roller contacts the end of the cross plate, and the third motor cooperates with the gear pair to drive the two rotating shafts to perform a rotational movement in the opposite direction of the movement in the vertical direction. At this time, the rotating shaft drives the driving wheel to drive the rubber sleeve to rotate synchronously. At this time, the cross plate located between the two rubber sleeves performs a linear movement in the horizontal direction under the drive of the two rubber sleeves. At this time, the detection roller rolls relative to the assembly surface of the cross plate. If the assembly surface of the cross plate is uneven, the detection roller will have a height change in the vertical direction. At this time, the detection roller pushes the support rod to change its position in the vertical direction. At this time, the support rod pushes the turntable to drive the cylinder to slide relative to the rotating rod. At this time, the pressure sensor is subjected to a change in the pressure of the pressing plate, that is, the technical effect of detecting the flatness of the assembly surface of the cross plate assembled and connected to the saddle can be completed;

[0030] 3. In the present invention, the electric roller shaft can drive the push plate to rotate, causing the free end of the push plate to move upward. At this time, the first motor drives the elliptical rectangular block to rotate at an angle of ninety degrees in the vertical direction. At this time, the elliptical rectangular block uses the elliptical rectangular groove to push and pull the push-pull plate, causing the push-pull plate to pull the plate body to slide along the first cavity. The first cavity pulls the push-pull rod to drive the electric roller shaft to move linearly. The electric roller shaft pulls the push plate to contact the connecting saddle on the support plate to limit the connecting saddle in the horizontal direction. At the same time, the pressing component can limit the connecting saddle in the vertical direction to achieve the technical effect of limiting the connecting saddle on the support plate;

[0031] 4. In the present invention, when the second motor pushes the rotating rod at the upper end to drive the end of the support rod connected to the detection roller to move in a circular motion, the two support rods are symmetrically facing inward. At this time, the second linear motion member is started to pull the support rod to translate in the horizontal direction, so that the detection roller is inserted into the limiting slide rail installed on the support rail and the detection roller is pressed against the inner wall of the limiting slide rail. The detection roller inserted into the limiting slide rail can limit the elliptical rectangular block to prevent the elliptical rectangular block from shaking or deflecting, thereby reducing the risk of the connecting saddle being separated from the support plate when moving in the vertical direction due to the reduced pressure of the push plate on the connecting saddle.

[0032] 5. In the present invention, when the connecting saddle located at a high place is transported to a low place for assembly with the cross plate, if the movement speed is too fast, the risk of collision between the connecting saddle and the cross plate will increase, and since the movement speed of the connecting saddle in the vertical direction is proportional to the rotation speed of the detection roller, when the rotation speed of the detection roller exceeds the preset speed threshold, the speed sensor starts the first linear moving part to pull the electric roller shaft to drive the push plate to contact the connecting saddle again, further limiting the connection saddle to prevent the connecting saddle from detaching from the support plate.

[0049] Preferably, the conveying assembly 7 includes a half-frame 701, a rotating shaft 702, a gear pair 703, a driving wheel 704, a third motor 706 and a third motor 706. Two groups of the half-frames 701 are symmetrically installed on the base plate 1. The two rotating shafts 702 are symmetrically rotatably installed on the half-frame 701. The two rotating shafts 702 are connected by transmission through the gear pair 703. One rotating shaft 702 is fixedly connected to the output shaft of the third motor 706 detachably installed on the half-frame 701. The lower end of the rotating shaft 702 is fixedly connected with a driving wheel 704. A rubber sleeve 705 is mounted on the driving wheel 704. The third motor 706 cooperates with the gear pair 703 to drive the two rotating shafts 702 to perform rotational motion in opposite directions in the vertical direction. At this time, the rotating shaft 702 drives the driving wheel 704 to drive the rubber sleeve 705 to rotate synchronously. At this time, the cross plate 10 located between the two rubber sleeves 705 performs linear motion in the horizontal direction under the push of the two rubber sleeves 705.

[0050] Preferably, the positioning and detection mechanism 6 includes a second linear motion member 601, a Y-shaped bracket 602, a support rod 603 and a detection roller 604, wherein the second linear motion member 601 is fixedly connected to the elliptical rectangular block 502, the output shaft of the second linear motion member 601 is fixedly connected to the Y-shaped bracket 602, one end of the support rod 603 is rotatably connected to the detection roller 604, and further includes:

[0051] The detection and rotation assembly 605 is installed on the Y-shaped bracket 602 and is used to drive the end of the support rod 603 to move in a circular motion or to detect the rolling force of the detection roller 604 in the vertical direction when it rolls on the surface of the cross plate 10.

[0052] The detection and rotation assembly 605 includes a second motor 6051, a turntable 6052, a cylinder 6053, a rotating rod 6054, a chuck 6055, a third elastic member 6056 and a pressing plate 6057. The turntable 6052 is fixedly connected to the other end of the support rod 603. The turntable 6052 is sleeved on the cylinder 6053 and fixedly connected to the cylinder 6053. Two second cavities (not shown in the figure) are symmetrically provided in the cylinder 6053. Two pressure sensors 6058 are symmetrically installed on the cylinder 6053. The pressure sensors 6058 are fixedly connected to the pressing plate 6057. One end of the rotating rod 6054 extends into the second cavity and is slidably connected to the chuck 6056 disposed in the second cavity. 55 is fixedly connected, a third elastic member 6056 is installed in the second cavity, and the two ends of the third elastic member 6056 are fixedly connected to the chuck 6055 and the pressing plate 6057 respectively, and the two rotating rods 6054 are both rotatably connected to the Y-shaped bracket 602, and the rotating rod 6054 located at the upper part is fixedly connected to the output shaft of the second motor 6051 detachably mounted on the Y-shaped bracket 602. The initial position of the support rod 603 has its free end located on the outside and it is perpendicular to the second linear motion member 601. At this time, driven by the lifting device 3, the detection roller 604 contacts the end of the horizontal plate 10. Since the horizontal plate 10 can perform linear motion under the transportation of the conveying assembly 7, the detection roller 604 is assembled relative to the horizontal plate 10. The detection roller 604 will roll on the surface. If the assembly surface of the horizontal plate 10 is uneven, the height of the detection roller 604 will change in the vertical direction. At this time, the detection roller 604 pushes the support rod 603 to change its position in the vertical direction. At this time, the support rod 603 pushes the turntable 6052 to drive the cylinder 6053 to slide relative to the rotating rod 6054 (the cylinder 6053 has a floating space relative to the rotating rod 6054, that is, the chuck 6055 located below is connected to one end of the rotating rod 6054 and the lower end inner wall of the second cavity located below has a floating space, and the chuck 6055 located above is connected to one end of the rotating rod 6054 and the upper end inner wall of the second cavity located above has a floating space). At this time, the pressure sensor 6058 is pressed by the pressing plate 6057. The pressing force changes, that is, the technical effect of detecting the flatness of the assembly surface of the horizontal plate 10 to which the saddle 9 is assembled can be achieved. If the detection is qualified, the lifting device 3 drives the Y-shaped bracket 602 to move in the vertical direction, causing the detection roller 604 to move away from the horizontal plate 10. At this time, the second motor 6051 drives the rotating rod 6054 at the upper end to drive the support rod 603 connected to the end of the detection roller 604 to move in a circular motion trajectory, causing the two support rods 603 to face inward symmetrically. At this time, the second linear motion member 601 is started to pull the support rod 603 to translate in the horizontal direction, causing the detection roller 604 to be inserted into the limiting slide rail 8 installed on the support rail 2 and causing the detection roller 604 to resist the inner wall of the limiting slide rail 8.That is, the detection roller 604 inserted into the limiting slide rail 8 is used to limit the elliptical rectangular block 502 to prevent the elliptical rectangular block 502 from shaking or deflecting, thereby reducing the risk of the connecting saddle 9 being separated from the support plate 4 when the push plate 508 reduces the pressure on the connecting saddle 9 and moves in the vertical direction.

[0053] Preferably, it also includes a speed sensor (not shown in the figure) installed at the free end of the support rod 603 to detect the rotation speed of the detection roller 604 installed at the free end of the support rod 603. The speed sensor is electrically connected to the first linear motion member 506. When the connecting saddle 9 located at a high place is transported to a low place for assembly with the cross plate 10, if the movement speed is too fast, the risk of collision between the connecting saddle 9 and the cross plate 10 will increase. Moreover, since the movement speed of the connecting saddle 9 in the vertical direction is proportional to the rotation speed of the detection roller 604, when the rotation speed of the detection roller 604 exceeds the preset speed threshold, the speed sensor starts the first linear motion member 506 to pull the electric roller shaft 507 to drive the push plate 508 to contact the connecting saddle 9 again, further limiting the connecting saddle 9 to prevent the connecting saddle 9 from separating from the support plate 4.

[0054] In the embodiment of the present invention, in the initial position of the support rod 603, its free end is located on the outside and is perpendicular to the second linear motion member 601. At this time, driven by the lifting device 3, the detection roller 604 contacts the end of the horizontal plate 10. At this time, the third motor 706 cooperates with the gear pair 703 to push the two rotating shafts 702 to perform a rotational movement in the opposite direction of the vertical movement. At this time, the rotating shaft 702 pushes the pushing wheel 704 to drive the rubber sleeve 705 to rotate synchronously. At this time, the horizontal plate 10 located between the two rubber sleeves 705 performs a linear movement in the horizontal direction under the push of the two rubber sleeves 705. At this time, the detection roller 604 rolls relative to the assembly surface of the horizontal plate 10. If the assembly surface of the horizontal plate 10 is uneven, the detection roller 604 will appear in the vertical direction. The height changes on the top, at this time, the detection roller 604 pushes the support rod 603 to change its position in the vertical direction, at this time, the support rod 603 pushes the turntable 6052 to drive the cylinder 6053 to slide relative to the rotating rod 6054, at this time, the pressure sensor 6058 is subjected to the pressure change of the pressing plate 6057, that is, it can complete the technical effect of detecting the flatness of the assembly surface of the horizontal plate 10 assembled and connected to the saddle 9. If the detection is qualified, the lifting device 3 drives the Y-shaped bracket 602 to move in the vertical direction, prompting the detection roller 604 to move away from the horizontal plate 10, and the electric roller shaft 507 drives the push plate 508 to rotate, prompting the free end of the push plate 508 to face upward, and at this time, the first motor 501 drives the elliptical rectangular block 502 to turn in the vertical direction. The elliptical rectangular block 502 uses the elliptical rectangular groove 504 to push and pull the push-pull plate 503, causing the push-pull plate 503 to pull the plate body to slide along the first cavity 402. The first cavity 402 pulls the push-pull rod 505 to drive the electric roller shaft 507 to perform linear motion. The electric roller shaft 507 pulls the push plate 508 to contact the connecting saddle 9 on the support plate 4 to limit the connecting saddle 9 in the horizontal direction. At the same time, the pressing component can limit the connecting saddle 9 in the vertical direction to achieve the technical effect of limiting the connecting saddle 9 on the support plate 4. At this time, the second motor 6051 pushes the rotating rod 6054 at the upper end to drive the end of the support rod 603 connected to the detection roller 604 to move in a circular motion trajectory, promoting Make the two support rods 603 face inward symmetrically, then start the second linear motion member 601 to pull the support rod 603 to translate in the horizontal direction, so as to insert the detection roller 604 into the limiting slide rail 8 installed on the support rail 2 and cause the detection roller 604 to contact the inner wall of the limiting slide rail 8, that is, use the detection roller 604 inserted into the limiting slide rail 8 to limit the elliptical rectangular block 502, prevent the elliptical rectangular block 502 from shaking or deflecting, and reduce the pressure of the push plate 508 on the connecting saddle 9, resulting in the risk of the connecting saddle 9 being separated from the support plate 4 when moving in the vertical direction. When the connecting saddle 9 located at a high place is transported to a low place for assembly with the cross plate 10, if the movement speed is too fast, the risk of the connecting saddle 9 colliding with the cross plate 10 will increase.And because the movement speed of the connecting saddle 9 in the vertical direction is proportional to the rotation speed of the detection roller 604, when the rotation speed of the detection roller 604 exceeds the preset rotation speed threshold, the rotation speed sensor starts the first linear motion member 506 to pull the electric roller shaft 507 to drive the push plate 508 to contact the connecting saddle 9 again, further limiting the connecting saddle 9 to prevent the connecting saddle 9 from separating from the support plate 4. After the connecting saddle 9 and the cross plate 10 are assembled and welded, the second linear motion member 601 pushes the detection roller 604 to separate from the limiting slide rail 8 and reset the detection roller 604. At this time, the conveying assembly 7 continues to push the cross plate 10, causing the assembled connecting saddle 9 and the cross plate 10 to separate from the assembly position.

[0055] A method for assembling an electric tractor, using the above-mentioned electric tractor assembly processing device to assemble the electric tractor, comprises the following steps:

[0056] S1, in the initial position of the support rod 603, the free end thereof is located outside and is perpendicular to the second linear motion member 601. At this time, driven by the lifting device 3, the detection roller 604 contacts the end of the horizontal plate 10;

[0057] S2, the third motor 706 cooperates with the gear pair 703 to push the two rotating shafts 702 to perform a rotational motion in the opposite direction of the vertical movement. At this time, the rotating shaft 702 pushes the pushing wheel 704 to drive the rubber sleeve 705 to rotate synchronously. At this time, the cross plate 10 located between the two rubber sleeves 705 performs a linear motion in the horizontal direction under the push of the two rubber sleeves 705. At this time, the detection roller 604 rolls relative to the assembly surface of the cross plate 10. If the assembly surface of the cross plate 10 is uneven, the detection roller 604 will have a height change in the vertical direction. At this time, the detection roller 604 pushes the support rod 603 to change its position in the vertical direction. At this time, the support rod 603 pushes the turntable 6052 to drive the cylinder 6053 to slide relative to the rotating rod 6054. At this time, the pressure sensor 6058 is subjected to a change in the pressure of the pressing plate 6057, that is, the technical effect of detecting the flatness of the assembly surface of the cross plate 10 assembled and connected to the saddle 9 can be completed;

[0058] S3. If the detection is qualified, the lifting device 3 drives the Y-shaped bracket 602 to move in the vertical direction, causing the detection roller 604 to move away from the horizontal plate 10, and the electric roller shaft 507 drives the push plate 508 to rotate, causing the free end of the push plate 508 to face upward. At this time, the first motor 501 drives the elliptical rectangular block 502 to rotate at an angle of ninety degrees in the vertical direction. At this time, the elliptical rectangular block 502 uses the opened elliptical rectangular groove 504 to push and pull the push-pull plate 503, causing the push-pull plate 503 to pull the plate body to slide along the first cavity 402. The first cavity 402 pulls the push-pull rod 505 to drive the electric roller shaft 507 to move linearly. The electric roller shaft 507 pulls the push plate 508 to contact the connecting saddle 9 on the supporting plate 4 to limit the connecting saddle 9 in the horizontal direction. At the same time, the pressing component can limit the connecting saddle 9 in the vertical direction to achieve the technical effect of limiting the connecting saddle 9 on the supporting plate 4.

[0059] S4, the second motor 6051 pushes the rotating rod 6054 at the upper end to drive the end of the support rod 603 connected to the detection roller 604 to move in a circular motion trajectory, so that the two support rods 603 face inward symmetrically, and at this time, the second linear motion member 601 is started to pull the support rod 603 to translate in the horizontal direction, so that the detection roller 604 is inserted into the limiting slide rail 8 installed on the support track 2 and the detection roller 604 is pushed against the inner wall of the limiting slide rail 8, that is, the detection roller 604 inserted into the limiting slide rail 8 is used to limit the elliptical rectangular block 502, so as to prevent the elliptical rectangular block 502 from shaking or deflecting, thereby reducing the impact of the push plate 508 on the elliptical rectangular block 502. The reduced resistance of the connecting saddle 9 leads to the risk of the connecting saddle 9 being separated from the support plate 4 when moving in the vertical direction. When the connecting saddle 9 located at a high place is transported to a low place for assembly with the cross plate 10, if the movement speed is too fast, the risk of the connecting saddle 9 and the cross plate 10 colliding will increase. In addition, since the movement speed of the connecting saddle 9 in the vertical direction is proportional to the rotation speed of the detection roller 604, when the rotation speed of the detection roller 604 exceeds the preset rotation speed threshold, the rotation speed sensor starts the first linear motion member 506 to pull the electric roller shaft 507 to drive the push plate 508 to contact the connecting saddle 9 again, further limiting the connecting saddle 9 to prevent the connecting saddle 9 from being separated from the support plate 4.

[0060] S5, after the saddle 9 and the cross plate 10 to be connected are assembled and welded, the second linear motion member 601 pushes the detection roller 604 to disengage from the limiting slide rail 8 and causes the detection roller 604 to reset. At this time, the conveying assembly 7 continues to push the cross plate 10, causing the assembled connection saddle 9 and the cross plate 10 to disengage from the assembly position.

[0061] Preferably, the above-mentioned linear motion parts are all electric telescopic rods, and the purpose of such a configuration is to push the object connected thereto to perform linear motion.

At this time, the support rod pushes the turntable to drive the cylinder to slide relative to the rotating rod.
