DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the present invention.

[0041] See also Figures 1 to 9The present invention provides a technical solution: an automatic conveying mechanism for quenching automobile leaf springs, comprising a base 1, a quenching equipment body 2 is fixedly connected to the left side of the base 1, a metal conveyor belt bracket 3 is fixedly connected to the right side of the base 1, an adjusting sleeve 4 is rotatably connected to the middle of the base 1, a support rod 5 is arranged at the axial position of the adjusting sleeve 4, and the bottom of the support rod 5 is rotatably connected to the top of the base 1. It should be noted that a one-way bearing is fixedly connected between the bottom of the support rod 5 and the top of the base 1 to ensure that the support rod 5 and the support sleeve 7 can stably rotate in one direction.

[0042] A transfer and conveying mechanism 6 that cooperates with the support rod 5 is movably connected between the surface of the adjustment sleeve 4 and the metal conveyor belt bracket 3. A support sleeve 7 is fixedly connected to the upper part of the support rod 5. A clamping mechanism 8 that cooperates with the transfer and conveying mechanism 6 is movably connected inside the support sleeve 7.

[0043] A limit baffle 9 is symmetrically arranged on one side of the metal conveyor belt support 3 away from the adjustment sleeve 4. It should be noted that the metal conveyor belt support 3 is composed of a conveyor support, a conveyor roller 601 and a metal belt, one end of the limit baffle 9 is fixedly connected to a micro motor, and the micro motor is fixedly connected to the side wall of the conveyor support. The micro motor turns the limit baffle 9 to limit the steel plate on the surface of the metal belt, and the two limit baffles 9 are arranged in a staggered manner, which is convenient for feeding the position of the clamping mechanism 8 in stages; the use of the above-mentioned limit baffle 9 and the metal conveyor belt support 3 are both existing technologies and will not be described in detail here.

[0044] The transfer conveying mechanism 6 includes a conveying roller 601, which is rotatably connected to the inside of the metal conveyor belt support 3, and a worm 602 is rotatably connected to the side of the metal conveyor belt support 3 close to the adjustment sleeve 4, and a synchronous belt 603 is movably connected between the surface of the worm 602 and one end of the conveying roller 601. It should be noted that the conveying roller 601 is rotated by the motor on the metal conveyor belt support 3, and the transmission method here is the existing technology and will not be described in detail; under the action of the synchronous belt 603, the conveying roller 601 can rotate synchronously with the worm 602.

[0045] The outer ring of the adjustment sleeve 4 is fixedly sleeved with a synchronous gear ring 604, the top of the base 1 is rotatably connected with a worm gear 605, the side wall of the worm gear 605 is meshed with the side wall of the worm 602, and the lower part of the worm gear 605 is fixedly sleeved with a circular gear 606, the side wall of the circular gear 606 is meshed with the side wall of the synchronous gear ring 604. It should be noted that: under the coordinated transmission of the worm gear 605 and the worm 602, the adjustment sleeve 4 can only rotate in one direction, ensuring the stability of the transfer and transportation of the automobile leaf spring.

[0046] Four main arc-shaped racks 607 are fixedly connected to the upper part of the inner ring of the adjusting sleeve 4, and an annular bracket 608 is arranged inside the adjusting sleeve 4. The bottom of the annular bracket 608 is fixedly connected to the top of the base 1, and the top of the annular bracket 608 is symmetrically rotatably connected to a reciprocating screw rod 609. The surface of the reciprocating screw rod 609 is threadedly connected to a screw sleeve 610, and the side wall of the screw sleeve 610 is fixedly connected to a trapezoidal push plate 611 that cooperates with the clamping mechanism 8, and the lower part of the reciprocating screw rod 609 is fixedly sleeved with an adjusting gear 612 that cooperates with the main arc-shaped racks 607.

[0047] The top of the annular bracket 608 is symmetrically fixedly connected with a guide rod 613, and the two guide rods 613 correspond to the two trapezoidal push plates 611. It should be noted that: since the side walls of the two trapezoidal push plates 611 are respectively slidably connected to the surfaces of the two guide rods 613, when the adjustment sleeve 4 rotates with the main arc-shaped rack 607 to the position of the adjustment gear 612 for meshing transmission, the adjustment gear 612 rotates with the reciprocating screw rod 609, and at this time, the screw sleeve 610 can move up and down with the trapezoidal push plates 611, and the trapezoidal push plates 611 periodically press the push rod 804 on the clamping mechanism 8.

[0048] The lower part of the inner wall of the adjustment sleeve 4 is symmetrically fixedly connected with a slave arc-shaped rack 614, and the inside of the adjustment sleeve 4 is provided with a gear rod 615 matched with the slave arc-shaped rack 614. The two gear rods 615 are symmetrically rotatably connected to the top of the base 1, and the top of the gear rod 615 and the lower part of the support rod 5 are both fixedly sleeved with a synchronous guide wheel 616, and a synchronous guide belt 617 is movably connected between the three synchronous guide wheels 616. It should be noted that: the two gear rods 615 are symmetrically arranged with the support rod 5 as the axis. When the adjustment sleeve 4 rotates with the slave arc-shaped rack 614 to the position of the gear rod 615, the gear rod 615 and the slave arc-shaped rack 614 are meshed and transmitted. In the process, under the cooperation of the synchronous guide wheel 616 and the synchronous guide belt 617, the support rod 5 can rotate 180 degrees with the support sleeve 7, so as to realize the transfer and switching of the leaf springs at both ends of the support sleeve 7.

[0049] In this embodiment, Figures 1 to 9 As shown, the side wall of the trapezoidal push plate 611 is fixedly connected with a guide ring, and the trapezoidal push plate 611 is slidably connected to the surface of the corresponding guide rod 613 through the guide ring. The two trapezoidal push plates 611 are respectively arranged on the front and rear sides of the support sleeve 7.

[0050] In this embodiment, Figures 1 to 9 As shown, the bottom of the annular bracket 608 is symmetrically fixedly connected with supporting legs, and the annular bracket 608 is fixedly connected to the top of the base 1 through the supporting legs.

[0051] In this embodiment, Figures 1 to 9As shown, the main arc-shaped rack 607 is arranged at the upper position of the annular bracket 608, and the slave arc-shaped rack 614 is arranged at the lower position of the annular bracket 608, and the four main arc-shaped racks 607 and the two slave arc-shaped racks 614 are staggered along the inner ring of the adjustment sleeve 4. It should be noted that: through this staggered arrangement, during the meshing transmission process of the main arc-shaped rack 607 and the corresponding adjustment gear 612, the slave arc-shaped rack 614 will not mesh with the corresponding gear rod 615; and the main arc-shaped rack 607 and the slave arc-shaped rack 614 are different in size, so as to avoid the meshing of the main arc-shaped rack 607 and the gear rod 615.

[0052] In this embodiment, Figures 1 to 9 As shown, the clamping mechanism 8 includes a transverse groove 801, which is provided with two transverse grooves 801, and the two transverse grooves 801 are symmetrically opened on both sides of the support sleeve 7. The interior of the transverse groove 801 is slidably connected with a moving rod 802, and the front and rear sides of the support sleeve 7 are provided with waist-shaped grooves 803, and the two waist-shaped grooves 803 correspond to the two transverse grooves 801 one by one. The interior of the waist-shaped groove 803 is slidably connected with a push rod 804 that cooperates with the transfer and conveying mechanism 6, and one end of the push rod 804 is fixedly connected to the surface of the adjacent moving rod 802, and a compression spring 805 is movably connected between the inner wall of the transverse groove 801 and the side wall of the push rod 804. It should be noted that the two trapezoidal push plates 611 correspond one to one with the two push rods 804. When the trapezoidal push plate 611 moves upward, it can carry the push rod 804 to slide inside the waist-shaped groove 803, so that the moving rod 802 moves toward the outside of the horizontal groove 801. When the trapezoidal push plate 611 moves downward, the compression spring 805 carries the moving rod 802 to reset.

[0053] The end of the moving rod 802 away from the support sleeve 7 is movably connected to a movable sleeve 806, and a movable groove 807 is provided inside the movable sleeve 806. A helical guide ring 808 is fixedly connected to the inner top surface of the movable groove 807, and a snap ring 809 is fixedly connected to the inner bottom surface of the movable groove 807. Four main slots 810 are equidistantly provided on the top of the snap ring 809 along the circumference, and four secondary slots 811 are equidistantly provided on the top of the snap ring 809 along the circumference. The four main slots 810 and the four secondary slots 811 are staggered. It should be noted that the main slots 810 and the adjacent secondary slots 811 are connected by an inclined surface, and the middle parts of the helical guide ring 808 and the snap ring 809 are both provided with circular holes.

[0054] The lower part of the movable sleeve 806 is provided with a limiting groove 812 which cooperates with the movable groove 807. The limiting groove 812 is slidably connected with a movable rod 813. The upper part of the movable rod 813 is movably inserted into the axial position of the bevel gear guide ring 808 and the retaining ring 809. The upper side wall of the movable rod 813 is fixedly connected with a retaining pin 814 which cooperates with the bevel gear guide ring 808. The retaining pin 814 is movably engaged with the inside of the adjacent main retaining groove 810. It should be noted that: when the movable rod 813 moves upward with the bayonet 814, the bayonet 814 will contact the bottom inclined surface of the bevel guide ring 808. At this time, the bayonet 814 moves and rotates with the movable rod 813 along the inclined trajectory at the bottom of the bevel guide ring 808, and adjusts the direction of the bayonet 814. As the bayonet 814 rotates, the bayonet 814 is no longer on the same vertical line with the main slot 810. When the movable rod 813 moves downward with the bayonet 814 and resets, the bayonet 814 falls on the inclined surface position at the top of the retaining ring 809, and slides along the inclined surface into the adjacent slave slot 811 for limiting, so that the bottom of the movable rod 813 can be fine-tuned and rotated inside the movable sleeve 806 each time it is pressed and moved upward, and the length extending out of the bottom of the movable sleeve 806 is automatically adjusted during the cooperation with the slave slot 811 and the main slot 810.

[0055] The bottom of the movable rod 813 passes through the movable sleeve 806 and is rotatably connected to a strip support box 815. U-shaped clamping plates 816 are slidably connected to both sides of the strip support box 815. The bottom of the movable sleeve 806 is symmetrically fixedly connected to an inclined slot plate 817. The upper parts of the two U-shaped clamping plates 816 are respectively slidably connected to the middle parts of the two inclined slot plates 817. It should be noted that a connecting bearing is fixedly connected between the bottom of the movable rod 813 and the top of the strip support box 815, so that the latch 814 will not interfere with the strip support box 815 during the rotation of the movable rod 813.

[0056] The movable sleeve 806 is connected to an adjustment plate 818 on the side of the movable rod 802 close to the movable sleeve 806, and a retaining ring 819 is fixedly sleeved on the surface of the movable rod 802. A pressing spring 820 is movably connected between the side wall of the adjusting plate 818 and the side wall of the adjacent retaining ring 819. The upper part of the adjusting plate 818 is fixedly connected to a pressure plate 821 that matches the quenching equipment body 2, and an adjustment groove 822 is provided in the middle of the pressure plate 821. A U-shaped adjustment frame 823 is fixedly connected to the top of the movable sleeve 806, and a cross bar 824 is fixedly connected between the two ends of the upper part of the U-shaped adjustment frame 823. The cross bar 824 is slidably connected to the inside of the adjustment groove 822, and an L-shaped pressure block 825 that matches the pressure plate 821 is fixedly connected to the side of the metal conveyor belt bracket 3 away from the adjusting sleeve 4. It should be noted that: when the moving rods 802 on both sides of the support sleeve 7 extend with the corresponding movable sleeves 806, the pressure plate 821 on one movable sleeve 806 will contact the surface of the quenching equipment body 2, and the pressure plate 821 on the other movable sleeve 806 will be released from the side wall of the L-shaped pressure block 825 on the metal conveyor belt bracket 3. During the pressure process of the pressure plate 821, the movable groove 807 slides downward at the corresponding end position of the moving rod 802 through the adjustment groove 822 and the cross bar 824 on the U-shaped adjustment frame 823.

[0057] In this embodiment, Figures 1 to 9 As shown, the middle part of the movable rod 813 is fixedly sleeved with a limiting ring, the limiting ring is arranged inside the limiting groove 812, and a limiting spring is movably connected between the top of the limiting ring and the inner top surface of the limiting groove 812.

[0058] In this embodiment, Figures 1 to 9 As shown, a sliding pin is fixedly connected between the two ends of the upper part of the U-shaped clamping plate 816, and the upper part of the U-shaped clamping plate 816 is slidably connected to the middle position of the inclined slot plate 817 through the sliding pin. It should be noted that: when the movable sleeve 806 moves downward with the inclined slot plate 817, the inclined slot on the inclined slot plate 817 and the sliding pin on the U-shaped clamping plate 816 cooperate and slide, and the two U-shaped clamping plates 816 can move relative to each other.

[0059] The bottom of the U-shaped clamping plate 816 is fixedly connected with an L-shaped pad, the side wall of the L-shaped pad is slidably connected with an L-shaped clamping block, and a compression spring is fixedly connected between the L-shaped clamping block and the side wall of the adjacent L-shaped pad. It should be noted that the bottom of the opposite side of the two L-shaped clamping blocks is set as an inclined surface, and when the L-shaped clamping block clamps the automobile leaf spring, the lower part of the L-shaped clamping block can support the automobile leaf spring to improve the clamping stability.

[0060] Rectangular grooves are provided on both sides of the strip support box 815, and a slide bar is fixedly connected between the two sides of the inner wall of the rectangular groove. The middle part of the U-shaped clamping plate 816 is slidably connected to the surface of the corresponding slide bar, and a return spring is movably sleeved on the surface of the slide bar.

[0061] In this embodiment, Figures 1 to 9 As shown, the top of the base 1 is symmetrically fixedly connected with a spring pad rod, and the top of the spring pad rod is fixedly connected with a trapezoidal positioning block, and the two trapezoidal positioning blocks correspond to the two moving rods 802 one by one, and the side walls of the trapezoidal positioning blocks overlap the side walls of the adjacent moving rods 802. It should be noted that: through the arrangement of the trapezoidal positioning blocks, when the support rod 5 rotates 180 degrees with the support sleeve 7, the trapezoidal positioning blocks can be used to block it, thereby improving the stability of the limit, and when the support rod 5 rotates with the support sleeve 7 again, the trapezoidal positioning blocks are compressed to shrink the spring pad rod to avoid interference.

[0062] A groove is provided on one side of the movable sleeve 806 close to the moving rod 802, and the end of the moving rod 802 away from the supporting sleeve 7 is slidably connected to the inside of the corresponding groove, and a restoring spring is fixedly connected between the inner top surface of the groove and the top of the moving rod 802. It should be noted that when the pressure plate 821 on the upper part of the movable sleeve 806 is compressed, the movable sleeve 806 can stably slide down on the surface of the moving rod 802 in cooperation with the groove.

[0063] The use method and advantages of the present invention: The working process of the automatic conveying mechanism for quenching automobile leaf springs is as follows:

[0064] like Figures 1 to 9 As shown, when the automobile leaf spring is transported by the metal conveyor belt support 3 to the position of the quenching equipment body 2, the automobile leaf spring is limited and blocked by the limit baffle 9. At the same time, during the operation of the metal conveyor belt support 3, the worm 602 is meshed with the worm gear 605 through the conveying roller 601 and the synchronous belt 603, so that the worm gear 605 is meshed with the synchronous gear ring 604 through the circular gear 606 and rotates synchronously with the adjustment sleeve 4;

[0065] During the rotation of the adjusting sleeve 4, when the main arc-shaped rack 607 on the adjusting sleeve 4 meshes with the adjacent adjusting gear 612, the adjusting gear 612 drives the reciprocating screw rod 609 to rotate, so that the trapezoidal push plate 611 moves up and down on the surface of the guide rod 613. When the trapezoidal push plate 611 moves up, the top of the trapezoidal push plate 611 presses against the surface of the adjacent push rod 804, so that the push rod 804 and the moving rod 802 extend out from the inside of the supporting sleeve 7. At this time, one moving rod 802 drives the corresponding movable sleeve 806 to move toward the direction of the quenching equipment body 2, and the other moving rod 802 drives the corresponding movable sleeve 806 to move toward the position of the L-shaped pressing block 825 on the side wall of the metal conveyor belt support 3. At this time, the pressing plates 821 on the upper parts of the two movable sleeves 806 are both pressed.

[0066] After the pressing plate 821 is compressed, the adjusting groove 822 on the pressing plate 821 cooperates with the cross bar 824 on the U-shaped adjusting frame 823 to slide, and the U-shaped adjusting frame 823 moves the movable sleeve 806 downward at the end position of the corresponding moving rod 802. At this time, the lower parts of the two movable sleeves 806 move toward the automobile leaf spring positions at the top of the quenching equipment body 2 and the metal conveyor belt bracket 3 respectively. During the downward movement of the movable sleeve 806, the bottoms of the two U-shaped clamps 816 at the bottom of the movable sleeve 806 are compressed, so that the U-shaped clamps 816 and the movable rod 813 rise inside the movable sleeve 806. At this time, the sliding pins on the U-shaped clamps 816 cooperate with the middle part of the inclined slot plate 817 to slide, so that the two U-shaped The clamping plate 816 moves relatively to clamp the corresponding automobile leaf spring, and at the same time, the rising movable rod 813 moves the bayonet 814 to the bottom of the helical guide ring 808. During the sliding process between the bayonet 814 and the inclined surface at the bottom of the helical guide ring 808, the bayonet 814 rotates and fine-tunes with the movable rod 813, so that the bayonet 814 is no longer on the same vertical line as the main slot 810 at the top of the snap ring 809. When the movable rod 813 moves downward and resets, the bayonet 814 slides along the inclined surface at the top of the snap ring 809 into the adjacent secondary slot 811. Due to the different depths of the main slot 810 and the secondary slot 811, the lower part of the U-shaped clamping plate 816 can still stably clamp the automobile leaf spring.

[0067] As the reciprocating screw 609 continues to rotate, the trapezoidal push plate 611 moves down and releases the pressure on the push rod 804. Under the elastic recovery of the compression spring 805, the moving rod 802 is retracted into the support sleeve 7, so that the two moving rods 802, the corresponding movable sleeves 806 and the clamped automobile leaf spring leave the position of the quenching equipment body 2 and the metal conveyor belt bracket 3. At this time, as the adjustment sleeve 4 continues to rotate, the arc-shaped rack 614 at the lower part of the inner wall of the adjustment sleeve 4 is meshed with the corresponding gear rod 615. Under the coordinated transmission of the synchronous guide wheel 616 and the synchronous guide belt 617, the support rod 5 rotates synchronously with the adjustment sleeve 4, and the support rod 5 rotates 180 degrees with the support sleeve 7, the moving rod 802, the movable sleeve 806 and the two automobile leaf springs to switch positions, and the automobile leaf spring at the position of the quenching equipment body 2 is transferred to the position of the metal conveyor belt bracket 3. At this time, the quenched automobile leaf spring is transported to the next process, and the unquenched automobile leaf spring at the position of the metal conveyor belt bracket 3 is transferred to the position of the quenching equipment body 2;

[0068] When the secondary arc-shaped rack 614 on the adjusting sleeve 4 is disengaged from the gear rod 615, the continuously rotating adjusting sleeve 4 brings the primary arc-shaped rack 607 to mesh with the adjusting gear 612 again. At this time, the moving rod 802 brings the movable sleeve 806 out again. After the pressure plate 821 on the movable sleeve 806 is pressed again, the movable sleeve 806 moves downward and the movable rod 813 rises inside it. Then, the latch 814 on the upper part of the movable rod 813 switches its position and falls into the corresponding main latch groove 810. At this time, the distance that the lower part of the movable rod 813 extends out of the movable sleeve 806 becomes longer, and the two U-shaped clamping plates 816 are in the opposite position of the two inclined slot plates 817. On one side, after the U-shaped clamp 816 releases the clamping of the automobile leaf spring, it is ensured that the two automobile leaf springs can stably fall on the corresponding quenching equipment body 2 and the metal conveyor with bracket after switching positions. Then the moving rod 802 is reset and the movable sleeve 806 is retracted again, so that the moving rod 802 is expanded and the lower part of the support sleeve 7 clamps the leaf spring and then retracts and rotates. Then the moving rod 802 is expanded again to remove the leaf spring and then retracts. In this reciprocating cycle, the adjustment sleeve 4 is used to rotate the support sleeve 7 in stages to automatically switch the loading and unloading of the automobile leaf springs on the quenching equipment body 2 and the metal conveyor with bracket, thereby improving work efficiency.
