The general shape is a toothed groove at the front end, the shaft rods are of different lengths, and the outermost end is round. After the automobile half-axle is processed into the basic shape, it needs to be quenched, machined, and surface treated.

In the final process, it is necessary to use an automatic straightening machine to automatically straighten the automobile half-axle, and multiple automobile half-axles need to be placed in an orderly manner on the fixed frame of the automatic straightening machine, and the automobile half-axles are transported to the inside in an orderly manner for straightening through automation.
[0003] Since the overall mass of the automobile half-axle is large and the different shapes at the two ends cause the center of gravity to be biased towards one end, when the conveying device of the automatic straightening machine transports automobile half-axles of different specifications, the center of gravity of the automobile half-axle is located outside the lifting point, the automobile half-axle will cause it to fall off the automatic straightening machine, thereby affecting the workers' normal operation of the automatic straightening machine to straighten the automobile half-axles. Therefore, the present application proposes an automobile half-axle chain frame conveying device. Summary of the invention

[0013] Compared with the prior art, the present invention has at least one of the following beneficial technical effects: The present invention arranges hydraulic parts. Since the pressures of the automobile half-axle on the hydraulic cylinder 1 in the two grooves are different and the two hydraulic pipes cross each other, the side with greater pressure will drive the hydraulic piston 2 and the frame to move to one side, so that the center of gravity of the automobile half-axle is close to the middle of the pushing frame. When the pushing frame drives the automobile half-axle to move on the fixed frame, it will not be separated from the machine body due to the center of gravity being close to the outer side of the pushing frame, which is convenient for workers to operate the automatic straightening machine to straighten automobile half-axles of different specifications.

First, the pushing frame 2 will move upward, so that the groove 201 will dock with the automobile half shaft and push it upward for a distance, so that the automobile half shaft is separated from the V-groove 102. The pushing frame 2 moves to one side of the body 1 by a distance of the width of the V-groove 102, and drives the automobile half shaft to move downward, so that the automobile half shaft re-enters the V-groove 102, and the automobile half shaft is separated from the groove 201. The pushing frame 2 moves the same distance in the opposite direction of the movement, thereby completing the conveying work of the automobile half shaft during the processing and straightening process.
[0023] In this embodiment, the adjustment mechanism 4 includes a concave frame 401 arranged below the push frame 2, and both ends of the concave frame 401 slide linearly on the surface of the body 1. The frame 401 is slidably connected to the body 1. Two connecting rods 402 are symmetrically arranged on one side of the push frame 2. A cross bar 403 is arranged between one end of the two connecting rods 402, and one end of the connecting rod 402 is fixedly connected to a cylinder 404. A motor 405 is fixedly connected to the frame 401, and a gear 406 is arranged at one end of the output shaft of the motor 405. The gear 406 A sliding member 5 is provided between the frame 404 and the cylinder 404. The sliding member 5 includes a disk 501 provided at one end of the cylinder 404. An inner gear 502 is provided on the inner wall of the disk 501. A second gear 503 and a third gear 504 are provided successively in the middle of the disk 501. The number of teeth of the internal gear 502 is greater than that of the second gear 503. A track 505 is provided on the surface of the disk 501. A guide column 506 sliding in the track 505 is provided on the surface of the frame 401. The motor 405 drives the gear 1 406 to be an active self-rotating gear. The gear 1 406 is a gear 503. 06 will initially mesh with gear 2 503, driving disk 501 to rotate forward. Since the number of teeth on gear 2 503 is one fifth of that on gear 1 406, when gear 1 406 separates from gear 2 503, gear 1 406 will mesh with internal gear 502 and drive disk 501 to rotate reversely. Since the number of teeth on internal gear 502 is one fourth of that on gear 1 406, during this process, guide post 506 passes from reciprocating guide rail 509 through inclined guide rail 511 and enters circumferential guide rail 510. The guide column 506 squeezes the inclined slide rail 511 so that the disc 501 moves vertically in the limiting groove 508 under the action of the limiting column 507, so that the gear 1 406 is separated from the internal gear 502 and then meshes with the gear 3 504. At this time, the guide column 506 will rotate one circle in the circular slide rail 510 and enter the inclined slide rail 511 again. The gear 1 406 is separated from the gear 3 504 and then meshes with the gear 2 503, thereby completing a gravity center detection of the car half-axle when the car half-axle is lifted and moved once.
[0024] A limiting column 507 is provided on the surface of the cylinder 404, and a limiting groove 508 is provided on the surface of the disk 501 for the limiting column 507 to slide. The disk 501 will drive the limiting column 507 to move in the limiting groove 508, so that the disk 501 can drive the cylinder 404 to rotate and move vertically on the surface of the cylinder 404.
[0025] Furthermore, the track 505 includes a reciprocating slide rail 509 and a circumferential slide rail 510, an inclined slide rail 511 is provided between the reciprocating slide rail 509 and the circumferential slide rail 510, a through slot 512 connected to the circumferential slide rail 510 is provided in the inclined slide rail 511, a slide post 513 is rotatably connected in the through slot 512, a long rod 1 514, a long rod 2 515 and a long rod 3 516 are continuously provided on the side of the slide post 513, and a blocking block 516 is provided at both ends of the through slot 512. 17, the blocking block 517 is made of magnet, and the long rod 3 516 and the long rod 1 514 are both made of iron. In the initial state, the long rod 1 514 contacts the blocking block 517 and is magnetically attracted to the surface of the blocking block 517. At this time, the inclined slide rail 511 and the circumferential slide rail 510 are kept unobstructed. When the guide column 506 moves on the circumferential slide rail 510 and contacts and drives the long rod 3 516, the long rod 1 514 is separated from the blocking block 517, and the long rod 3 514 is moved. 16 contacts and magnetically connects with the blocking block 517. At this time, the second long rod 515 moves from the through slot 512 into the circumferential slide rail 510, and the first long rod 514 is located in the inclined slide rail 511, so that the circumferential slide rail 510 is closed. The guide post 506 is blocked by the second long rod 515 and moves into the inclined slide rail 511, thereby contacting and driving the first long rod 514 to move into the through slot 512, so that the first long rod 514 is magnetically connected with the blocking block 517 again. The long rod three 516 is separated from the blocking block 517 by suction contact, so that the disk 501 moves vertically on the surface of the cylinder 404, so that the gear one 406 meshes with the gear two 503 and the gear three 504 successively, that is, when the guide column 506 is in the reciprocating slide rail 509, the gear one 406 meshes with the gear two 503 and the internal gear 502, and when the guide column 506 is in the circumferential slide rail 510, the gear one 406 meshes with the gear three 504.
[0026] Furthermore, the hydraulic component 3 includes a hydraulic cylinder 1 301 correspondingly arranged in the two grooves 201, a hydraulic piston 1 302 is arranged in the hydraulic cylinder 1 301, one end of the hydraulic cylinder 1 301 is connected with a hydraulic pipe 303, one end of the two hydraulic pipes 303 are connected with a hydraulic cylinder 2 304, a hydraulic piston 2 305 is slidably connected in the hydraulic cylinder 2 304, hydraulic oil 306 is arranged between the hydraulic piston 1 302 and the hydraulic piston 2 305, a connecting rod 307 is arranged between the two hydraulic pistons 2 305, and the connecting rod 307 is fixedly connected to the frame 401, and the two The hydraulic pipes 303 intersect each other, and the inner diameter of the hydraulic cylinder 1 301 is larger than the inner diameter of the hydraulic cylinder 2 304. The same volume of hydraulic oil 306 is higher in the hydraulic cylinder 2 304, so that the piston 2 moves a longer distance, thereby driving the frame 401 and the push frame 2 to move horizontally in the body 1. The connecting rod 307 is made of rigid material. The hydraulic cylinder 1 301 and the hydraulic cylinder 2 304 are both made of rigid material, and the inner wall is smooth to form a closed space with the hydraulic piston 1 302 and the hydraulic piston 2 305. The hydraulic oil 306 will not leak out, and the top of the hydraulic piston 1 302 A pressure plate is provided to contact and squeeze the half shaft of the automobile in the groove 201, so that the gravity of the half shaft of the automobile on the pressure plate is converted into a thrust on the hydraulic piston 1 302, so that the hydraulic oil 306 in the hydraulic piston 1 302 enters the hydraulic cylinder 2 304 through the hydraulic pipe 303, thereby pushing the hydraulic piston 2 305 to move. In the initial state, since the hydraulic cylinders 1 301 in the two corresponding grooves 201 are completely consistent and thus remain in a static state, when the thrusts received by the two hydraulic pistons 1 302 are unequal, the hydraulic piston 1 302 with a larger pressure will move to the other side. The hydraulic piston 2 305 moves downward, and with the assistance of the hydraulic oil 306, the hydraulic piston 2 305 moves actively and drives the connecting rod 307 to make the other hydraulic piston 2 305 move passively in the hydraulic cylinder 2 304, and with the assistance of the hydraulic oil 306, the other hydraulic piston 1 302 moves upward in the hydraulic cylinder 1 301, thereby detecting the center of gravity of the automobile half-axle placed in the two grooves 201. At the same time, the two hydraulic pistons 2 305 and the connecting rod 307 will drive the frame 401 and the pushing frame 2 to move, so that the center of gravity of the automobile half-axle is close to the middle of the pushing frame 2.
[0027] In this embodiment, by placing a plurality of automobile half shafts into the V-shaped groove 102 on the fixing frame 101, the machine body 1 is started to work, and first the motor 405 drives the gear 1 406 to rotate autonomously, and the gear 1 406 engages to drive the gear 2 503 to rotate, and at this time the gear 2 503 and the disk 501 rotate, and the cylinder 404 and one end of the connecting rod 402 rotate through the limiting groove 508 and the limiting column 507, and the two connecting rods 402 move at the same time through the cross bar 403, so that the push frame 2, the cross bar 403 and the two connecting rods 402 form a parallelogram, so that the push frame 2 moves in the concave frame 401. At this time, the push frame 2 will push the half shaft of the car to move upward for a short distance, and then the gear 1 406 is separated from the gear 2 503 and meshed with the internal gear 502. At this time, the rotation direction of the disc 501, the cylinder 404 and the connecting rod 402 is reversed. At this time, the push frame 2 moves downward in the concave frame 401, which can quickly cause the half shaft of the car to be squeezed with the hydraulic cylinder. The pressure of the half shaft of the car is different in the two grooves 201 at the same time, so as to judge the approximate direction of the center of gravity of the half shaft of the car, and by squeezing the hydraulic oil 306, the piston moves horizontally above the body 1, so that the connecting rod 307 drives the concave The frame 401 moves to ensure that the center of gravity of the half shaft of the automobile is basically in the middle of the two rows of pushing frames 2, so as to prevent the pushing frames 2 from falling off when pushing up the half shaft of the automobile. Since the number of tooth grooves of the inner gear 502 is greater than the number of tooth grooves of the gear 2 503, during this process, the guide column 506 is always in the track 505. When the pushing frame 2 moves upward, the guide column 506 slides in the reciprocating slide rail 509, and when the inner gear 502 drives the cylinder 404 to reverse, the guide column 506 enters the inclined slide rail 511. When the inner gear 502 separates from the gear 1 406, the guide column 506 completely enters the circumferential slide rail 510. At this time, the gear 406 is The engagement of gear 1 406 with gear 2 503 will drive the disc 501 again, and the cylinder 404 and the connecting rod 402 will change the direction of movement, so that the pushing frame 2 moves upward in the frame 401, and the gear 1 406 will engage and drive the gear 2 503 to rotate one circle, thereby causing one end of the connecting rod 402 to rotate one circle, and the pushing frame 2 performs a reciprocating motion in the frame 401. The automobile half-axle in the V-groove 102 can move into the body 1 by the distance of the V-groove 102, which is beneficial for the body 1 to reduce the occurrence of the automobile half-axle falling off when it moves on the fixing frame 101 when straightening automobile half-axles of different specifications.
[0028] The above specific embodiments are only several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
