Technical Field

[0002] Steering tie rods are crucial components in automotive steering mechanisms, directly impacting vehicle handling stability, operational safety, and tire lifespan. During tie rod assembly, the ball joint and connecting rod are connected via screw nuts (either positive or negative threads) to allow for quick adjustment of the tie rod length.

[0003] According to invention patent application CN108907695B, published on December 13, 2019, a nut clamping device is disclosed. The nut clamping device includes: a material-grabbing mechanism for clamping nuts; and a nut-locking mechanism, which includes: a first driving part; and a sleeve part having a receiving hole for accommodating nuts. The first driving part is drivenly connected to the sleeve part so that the first driving part drives the nut to rotate through the sleeve part. Specifically, when the sleeve part removes the nut from the screw part, the material-grabbing mechanism clamps the nut in the receiving hole; or, when the material-grabbing mechanism transfers the nut to the receiving hole, the sleeve part installs the nut onto the screw part. Its main technical advantage is that the material-grabbing mechanism and the nut-locking mechanism enable rapid installation or removal of nuts. In practical operation, when it is necessary to remove the nut from the screw section, the first drive unit drives the sleeve section to rotate, thereby placing the nut removed from the screw section into the receiving hole, and then the material-taking mechanism clamps the nut in the receiving hole; when it is necessary to install the nut onto the screw section, the material-taking mechanism transfers the nut to the receiving hole, the first drive unit drives the sleeve section to rotate, and the sleeve section installs the nut onto the screw section. The nut clamping device of the present invention can realize the rapid installation or removal of nuts through the material-taking mechanism and the nut locking mechanism.

To address this, an automatic assembly machine for automotive steering rod connectors is proposed, aiming to solve the problem of low efficiency in the assembly of the ball joint and connecting rod of the steering tie rod in the existing technology.

[0045] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0046] Please see Figure 1 —16, an automatic assembly machine for automotive steering rod connectors, comprising a frame 1, and further comprising, sequentially arranged:

[0047] The feeding mechanism 2 includes a reciprocating feeding frame 21, on which a ball-head connecting rod 31 and a Y-shaped connecting rod 32 are provided;

[0048] The misaligned nut connection mechanism 4 includes a sliding seat 41 facing each other and a fixed seat 46 at both ends of the frame 1. The sliding seat 41 is provided with a tightening mechanism 48. By sliding the sliding seat 41, the ball head connecting rod 31 and the Y-type connecting rod 32 are respectively inserted into the fixed seats 46 at both ends. The tightening mechanism 48 tightens the nuts and connects them to the ball head connecting rod 31 and the Y-type connecting rod 32 respectively. The misaligned nut connection mechanism 4 has a misaligned tightening station.

[0049] A first moving mechanism 5 is provided between the feeding mechanism 2 and the misaligned nut connecting mechanism 4. The first moving mechanism 5 moves the steering rod on the feeding frame 21 to the misaligned tightening position.

[0050] The second moving mechanism 6 is mounted on the frame 1, and the second moving mechanism 6 is equipped with a transfer frame 61;

[0051] The nut column tightening mechanism 7 is installed on the frame 1. The nut column tightening mechanism 7 includes a clamping mechanism 71 and a rotating mechanism 72. The clamping mechanism 71 clamps the nut column, and the rotating mechanism 72 drives the clamping mechanism 71 to rotate so that the two ends of the nut column are respectively connected to the ball head connecting rod 31 and the Y-type connecting rod 32. The nut column tightening mechanism 7 has a nut column tightening station.

[0052] Nut tightening mechanism 8, which is mounted on frame 1, has a nut tightening station;

[0053] The second moving mechanism 6 drives the transfer frame 61 to keep moving, so that the ball head connecting rod 31 and the Y-type connecting rod 32 move sequentially at the misaligned tightening station, the nut column tightening station, and the nut clamping station.

[0054] The frame 1 is sequentially equipped with a feeding mechanism 2, a first moving mechanism 5, a misaligned nut connecting mechanism 4, a second moving mechanism 6, and a nut column tightening mechanism 7. The ball head connecting rod 31 and the Y-type connecting rod 32 on the feeding mechanism 2 can be transferred to the misaligned nut connecting mechanism 4 through the first moving mechanism 5. A tightening nut can be connected to the ball head connecting rod 31 and the Y-type connecting rod 32 through the misaligned tightening station of the misaligned nut connecting mechanism 4. Then, the Y-type connecting rod 32 and the ball head connecting rod 31 are connected through the nut column tightening mechanism 7 to ensure that the ball head connecting rod 31 and the Y-type connecting rod 32 can maintain a stable connection.

[0055] Specifically, the feeding mechanism 2 includes a reciprocating feeding frame 21, with a ball-head connecting rod 31 and a Y-shaped connecting rod 32 mounted on the feeding frame 21. The feeding frame 21 maintains reciprocating motion and provides the ball-head connecting rod 31 and the Y-shaped connecting rod 32 to the first moving mechanism 5. The operator only needs to place the ball-head connecting rod 31 and the Y-shaped connecting rod 32 onto the feeding frame 21, which can greatly reduce the amount of manual labor.

[0056] The misaligned nut connection mechanism 4 includes opposing sliding seats 41 and fixed seats 46 located at both ends of the frame 1. Specifically, two slide rails are provided on the frame 1, with two sliding seats 41 respectively located on the slide rails and two fixed seats 46 located at both ends of the slide rails. A tightening mechanism 48 is provided on the fixed seats 46. A limiting seat 411 is provided on the sliding seats 41, and the limiting seat 411 has a limiting groove for accommodating the ball-head connecting rod 31 and the Y-shaped connecting rod 32. The ball-head connecting rod 31 and the Y-shaped connecting rod 32 on the feeding rack 21 are placed into the limiting seat 411 by the first moving mechanism 5. A sliding drive unit 421 is provided on the frame 1, and the output end of the sliding drive unit 421 is connected to the sliding seat 41. The sliding drive unit 421 can drive the sliding seat 41 to move on the slide rail, so that the ball head connecting rod 31 and the Y-type connecting rod 32 in the limiting seat 411 provided on the sliding seat 41 can be respectively inserted into the tightening mechanism 48 of the two fixed seats 46 for tightening, so that the two tightening nuts are respectively connected to the ball head connecting rod 31 and the Y-type connecting rod 32. Preferably, one of the limiting seats 411 is slidably connected to one of the sliding seats 41. A sliding drive cylinder is provided on the outer wall of one side of the frame 1, and its output end is connected to the limiting seat 411. The sliding drive cylinder can drive one of the limiting seats 411 to slide on the sliding seat 41, so that the two limiting seats 411 can move towards the fixed seats 46 at both ends in a staggered manner.

[0057] Furthermore, a wedge-shaped rod 412 is fixedly installed on the outer wall of the top of the sliding seat 41. The wedge-shaped structure at the top of the wedge-shaped rod 412 allows it to be inserted into and held by the ball-head connecting rod 31 and the Y-shaped connecting rod 32. It also works with the limiting seat 411 to mount the ball-head connecting rod 31 and the Y-shaped connecting rod 32 onto the sliding seat 41. A connecting rod limiting mechanism 413 is provided on the outer wall of the top of the sliding seat 41. The connecting rod limiting mechanism 413 includes a limiting mounting seat 4131, a ball-head rod 4132, and a drive cylinder, limiting the movement of the connecting rod. Mounting base 4131 is fixedly mounted on the outer wall of one side of sliding base 41. Ball head rod 4132 is rotatably connected to limiting mounting base 4131. Drive cylinder is fixedly mounted on limiting mounting base 4131. Its output end is movably connected to one end of ball head rod 4132. By maintaining reciprocating motion through the output end of drive cylinder, ball head rod 4132 can be kept swinging, thereby maintaining contact with ball head connecting rod 31 and Y-type connecting rod 32, and fixing ball head connecting rod 31 and Y-type connecting rod 32 in limiting base 411.

[0058] A second moving mechanism 6 is provided on the frame 1, and a transfer frame 61 is provided on the second moving mechanism 6. The ball head connecting rod 31 and the Y-type connecting rod 32 are moved sequentially to the misaligned tightening station, the nut column tightening station and the nut tightening station through the second moving mechanism 6.

[0059] The nut column tightening mechanism 7, which is installed on the frame 1, includes a clamping mechanism 71 and a rotating mechanism 72. The ball-head connecting rod 31 and the Y-type connecting rod 32 are moved from the misaligned tightening station to the nut column tightening station by the second moving mechanism 6. The clamping mechanism 71 clamps the nut column, and the rotating mechanism 72 drives the clamping mechanism 71 to rotate so that the two ends of the nut column are connected to the ball-head connecting rod 31 and the Y-type connecting rod 32 respectively.

[0060] The nut tightening mechanism 8 specifically includes the clamping mechanism 71 and the rotating mechanism 72 of the nut column tightening mechanism 7 mentioned above. They have the same structure and are used to tighten the tightening nuts that are connected to the ball head connecting rod 31 and the Y-type connecting rod 32 through the misaligned nut connecting mechanism 4.

[0061] In this invention, the first moving mechanism 5 transfers the ball-end connecting rod 31 and the Y-type connecting rod 32, which need to be connected, from the feed rack 21 to the misaligned tightening station. The sliding seat 41 of the misaligned nut connecting mechanism 4 drives the ball-end connecting rod 31 and the Y-type connecting rod 32 into the tightening mechanism 48 on the two end fixing seats 46, respectively. The tightening mechanism 48 connects two tightened nuts to the ball-end connecting rod 31 and the Y-type connecting rod 32, respectively. Then, the second moving mechanism 6 transfers the ball-end connecting rod 31 and the Y-type connecting rod 32 from the misaligned tightening station to the nut column tightening station, where the clamping mechanism 71 of the nut column tightening mechanism 7 holds them in place. The nut column is held and the clamping mechanism 71 is driven to rotate by the rotating mechanism 72 so that both ends of the nut column are connected to the ball head connecting rod 31 and the Y-type connecting rod 32 respectively. Then, the ball head connecting rod 31 and the Y-type connecting rod 32 at the misaligned tightening station and the ball head connecting rod 31 and the Y-type connecting rod 32 at the nut column tightening station are fed to the next station through the transfer frame 61 of the second moving mechanism 6. The ball head connecting rod 31 and the Y-type connecting rod 32 at the nut column tightening station are transferred to the nut tightening station through the second moving mechanism 6. The tightening nut is tightened by the nut tightening mechanism 8, thereby realizing complete assembly, which can reduce manual input and improve production efficiency.

The diameter of the feeding hole 455 is adapted to the outer diameter of the tightening nut, allowing the tightening nut to pass through the feeding hole 455. The push rod 454 is movably disposed on the frame 1. Figure 8 As shown, one end of the push rod 454 is provided with a groove that matches the end face of the tightening nut, which is used to keep in contact with the tightening nut and push the tightening nut to keep moving. The movable push rod 454 can be inserted into the feed hole 455. The push rod 454 is inserted into the feed hole 455, and the tightening nut is pushed out of the positioning frame 453 by the groove provided on the outer wall of the push rod 454.

The clamping mechanism 71 is driven to rotate by the rotating mechanism 72 so that the nut column is kept rotating, thereby connecting the ball-head connecting rod 31 and the Y-shaped connecting rod 32.

[0066] The nut tightening mechanism 7 also includes a positioning mechanism 77 mounted on the frame 1. The positioning mechanism 77 is used to maintain contact with the ball joint connecting rod 31 and the Y-type connecting rod 32. Specifically, the positioning mechanism 77 includes a movable seat 771 slidably connected to the frame 1. A positioning rod 772 is fixedly installed on the outer wall of the top of the movable seat 771. Preferably, the top of the positioning rod 772 has a wedge-shaped structure, which allows the positioning rod 772 to maintain insertion with one end of either the ball joint connecting rod 31 or the Y-type connecting rod 32. Figure 2 As shown, a fixing member 773 is fixedly installed on the outer wall of one side of the movable seat 771. The fixing member 773 has a groove that matches the outer wall of the ball head connecting rod 31 and the Y-shaped connecting rod 32. The ball head connecting rod 31 and the Y-shaped connecting rod 32 can be placed on the fixing member 773 and the positioning rod 772 on the movable seat 771 by the second moving mechanism 6. Preferably, there are two positioning mechanisms 77. The two positioning mechanisms 77 are symmetrical about the support plate 73. The ball head connecting rod 31 and the Y-shaped connecting rod 32 can be respectively mounted on both sides of the support plate 73 by the positioning mechanisms 77. A moving drive member 775 is provided on the outer wall of one side of the frame 1 and is connected to the movable seat 771. The moving drive member 775 can drive the movable seat 771 to keep sliding.

[0067] like Figure 4 , Figure 5 As shown, the rotating mechanism 72 includes an incomplete gear ring 721, a drive wheel 722, a positioning wheel 723, and a connecting plate 724. Further, the number of positioning wheels 723 is several, and the positioning wheels 723 are rotatably connected to the outer wall of one side of the support plate 73 via connecting shafts. Figure 7As shown, the first positioning groove 75 is formed on the outer wall of one side of the incomplete gear ring 721, and the first positioning groove 75 is adapted to the insertion groove 74, which facilitates the entry of the nut post, ball joint connecting rod 31, and Y-shaped connecting rod 32 into the incomplete gear ring 721. An annular groove 7211 is formed on the outer wall of one side of the incomplete gear ring 721. The connecting plate 724 is generally circular in structure, and a connecting strip is fixedly set on the peripheral wall of the circular structure. The connecting strip is fixedly connected to the outer wall of the support plate 73 through a connecting shaft. Several guide wheels 725 are rotatably set on the outer wall of one side of the connecting plate 724. Specifically, several guide wheels 725 are rotatably set on the outer wall of one side of the connecting plate 724. The guide wheels 725 are arranged in a circular array on the outer wall of the connecting plate 724. Preferably, the diameter of the guide wheel 725 is adapted to the width of the annular groove 7211, so that the incomplete gear ring 721 can be rotatably connected to the connecting plate 724 through the annular groove 7211 and the guide wheel 725. The connecting plate 724 is fixedly connected to the support plate 73, so that the incomplete gear ring 721 can be rotatably connected between the support plate 73 and the connecting plate 724. The outer wall of the positioning wheel 723 abuts against the circumferential outer wall of the incomplete gear ring 721, which can prevent the incomplete gear ring 721 from circumferentially shaking and ensure that the incomplete gear ring 721 can rotate stably.

[0068] like Figure 6 and Figure 7 As shown, the drive wheel 722 is provided with teeth, and there are two drive wheels 722. Both drive wheels 722 are rotatably connected to the outer wall of the support plate 73 through a rotating shaft, and both drive wheels 722 are engaged with the incomplete gear ring 721. The drive wheels 722 can drive the incomplete gear ring 721 to rotate between the connecting plate 724 and the support plate 73.

[0069] A drive mechanism 78 is also provided on the support plate 73. The drive mechanism 78 can be a mechanical component such as a drive motor that has a rotating output shaft. As an embodiment provided by the present invention, the drive mechanism 78 includes a motor 781, a first gear 782, a second gear 783, a first transmission wheel 784, a second transmission wheel 785, a third transmission wheel 786, and a transmission belt 787. The motor 781 is fixedly installed on the outer wall of one side of the support plate 73. The first gear 782 is fixedly installed on the output end of the motor 781. The second gear 783 is rotatably connected to the support plate 73 through a rotating shaft, and the rotating shaft passes through and extends to the outer wall of the other side of the support plate 73. The second gear 783 and the first gear 782 are meshed. The motor 781 can drive the first gear 782 to rotate, and the rotation of the first gear 782 drives the second gear 783 to remain stationary. The first transmission wheel 784 is fixedly mounted on the shaft of the second gear 783. When the second gear 783 rotates, it can synchronously drive the first transmission wheel 784 to rotate. The second transmission wheel 785 is fixedly mounted on the shaft of one of the drive wheels 722, and the third transmission wheel 786 is fixedly mounted on the shaft of the other drive wheel 722. The transmission belt 787 connects the first transmission wheel 784, the second transmission wheel 785, and the third transmission wheel 786. When the output end of the motor 781 rotates, the first gear 782 drives the second gear 783 to rotate. The first transmission wheel 784, which is coaxially connected to the second gear 783, and the transmission belt 787 drive the second transmission wheel 785 and the third transmission wheel 786 to rotate. This allows the drive wheel 722 to rotate, thereby driving the incomplete gear ring 721 to rotate.

[0070] Furthermore, the clamping mechanism 71 includes a guide post 731 fixedly mounted on the outer wall of the support plate 73, a drive piece 732 slidably connected to the guide post 731, a rotating block 733, and a clamping block 734. A connecting post 735 is provided on the outer wall of the incomplete gear ring 721, and a receiving groove 736 is formed on the outer wall of the connecting post 735. The receiving groove 736 is adapted to the insertion groove 74 for inserting the ball-head connecting rod 31 and the Y-shaped connecting rod 32 into the clamping mechanism 71 through the second moving mechanism 6. An inclined groove is formed on the inner wall of the receiving groove 736. A slider is provided on the outer wall of the clamping block 734. The clamping block 734 is slidably connected to the inclined groove through the slider on the outer wall, so that the clamping block 734 is connected to the incomplete gear ring 721. A circular groove 737 is provided on the inner wall of one side of the drive plate 732. Specifically, the rotating block 733 has a semi-circular structure. The clamping block 734 is fixedly installed on the outer wall of one side of the rotating block 733. The rotating block 733 is located inside the circular groove 737, so that when the incomplete gear ring 721 is rotating, the rotating block 733 can be kept rotating inside the circular groove 737. A drive unit 738 is fixedly installed on the outer wall of one side of the support plate 73. As an embodiment of the present invention, the drive unit 738 is specifically a cylinder. The output end of the drive unit 738 extends through and to the outer wall of one side of the support plate 73. The output end of the drive unit 738 is fixedly installed on the drive plate 732. The drive plate 732 can be driven to slide along the guide post 731 by the drive unit 738. A limit slot 7311 is formed on the outer wall of one side of the guide post 731. A plug-in mechanism 7312 is provided on the outer wall of one side of the support plate 73. The plug-in mechanism 7312 includes a plug connector 7313 and a plug-in drive. Component 7314, specifically a cylinder, is a plug-in drive component 7314 fixedly installed on the outer wall of one side of the support plate 73. A plug connector 7313 is fixedly installed on the output end of the plug-in drive component 7314. The plug connector 7313 is driven by the plug-in drive component 7314 to maintain movement, allowing one end of the plug connector 7313 to be inserted into the limiting slot 7311. Maintaining the plug connector 7313 in contact with the limiting slot 7311 keeps it abutting against the outer wall of the drive plate 732, thus preventing the drive plate 732 from moving outward and ensuring that the clamping block 734 can stably clamp the nut column. A second positioning groove 76 is formed on the outer wall of one side of the drive plate 732 and can be adapted to the first positioning groove 75, allowing the ball joint connecting rod 31 and the Y-shaped connecting rod 32 to be inserted into the support plate 73.

[0071] In use, the drive plate 732 is driven to move toward the support plate 73 by the output end of the drive unit 738. Since the clamping block 734 is slidably connected to the incomplete gear ring 721 through the inclined groove and the slider, when the drive plate 732 moves toward the support plate 73, the two clamping blocks 734 can move toward each other, so that the clamping blocks 734 can clamp the nut column.

[0072] It also includes a nut column supply mechanism 10, which is located on one side of the frame 1. The nut column supply mechanism 10 includes a feeding rack 101, a movable limit plate 102, a feeding block 103, a feeding cylinder 104, a moving table 105, a moving drive unit 110, a lifting cylinder 106, and a cylinder gripper 107. Specifically, the feeding rack 101 is fixedly installed on the outer wall of one side of the frame 1, and a feeding plate 108 is fixedly installed inside the feeding rack 101. The feeding plate 108 divides the interior of the feeding rack 101 into inclined sections. The material feeding channel allows the nut column to move along with the feeding channel after it enters the feeding frame 101. The movable limiting plate 102 is slidably connected to the inner wall of the feeding plate 108. A movable cylinder 109 is provided on the outer wall of one side of the feeding plate 108. The output end of the movable cylinder 109 passes through and extends to the inner wall of one side of the feeding plate 108, and the output end of the movable cylinder 109 is fixedly connected to the movable limiting plate 102. The movable limiting plate 102 can push the nut column in the feeding channel, thus preventing the polygonal nut column from getting stuck.

[0073] The moving stage 105 is slidably connected to the outer wall of one side of the frame 1. The moving drive unit 110 is fixedly installed on the outer wall of one side of the frame 1. The moving stage 105 is fixedly connected to the output end of the moving drive unit 110. Specifically, the moving drive unit 110 is a moving module that can drive the moving stage 105 to reciprocate along a fixed direction through its output end. The unloading cylinder 104 is fixedly installed below the unloading rack 101. The unloading block 103 is fixedly installed at the output end of the unloading cylinder 104. A support groove adapted to the shape of the nut column is opened on the outer wall of one side of the unloading block 103 to support the nut column falling from the unloading channel and to transfer a single nut column to the outside of the unloading rack 101 through the unloading cylinder 104. The lifting cylinder 106 is fixedly installed on the outer wall of one side of the moving stage 105. A connecting positioning plate is fixedly installed on the outer wall of one side of the lifting cylinder 106. The nut column gripper cylinder 107 is fixedly installed on the connecting positioning plate. The nut column can be gripped on the unloading block 103 by the nut column gripper cylinder 107, and the positioning plate can be lifted by the lifting cylinder 106 to prevent the nut column gripper cylinder 107 from interfering with the nut column tightening mechanism 7 during movement. The nut column gripper cylinder 107 is moved to the support plate 73 by the moving drive unit 110, and the nut column is inserted into the insertion slot 74 of the support plate 73 by the lifting cylinder 106. Then, the clamping block 734 is driven by the clamping mechanism 71 to clamp the nut column. After that, the lifting cylinder 106 and the moving drive unit 110 are reset. The two moving drive components 775 on both sides drive the two positioning mechanisms 77 to move towards the nut column, so that the ball head connecting rod 31 and the Y-type connecting rod 32 are connected to the nut column. Then, the clamping mechanism 71 is driven to rotate by the rotating mechanism 72 to connect the nut column and the ball head connecting rod 31 and the Y-type connecting rod 32.

[0074] It should be noted that the nut tightening mechanism 8 and the nut column tightening mechanism 7 have the same structure, including two support plates 73. Both support plates 73 are equipped with a rotating mechanism 72 and a clamping mechanism 71. The structure and function of the support plate 73, rotating mechanism 72 and clamping mechanism 71 in the nut tightening mechanism 8 are the same as those in the nut column tightening mechanism 7, and will not be described in detail here.

[0075] The nut tightening mechanism 8 also includes two rod positioning components 81, which are respectively located on both sides of the nut tightening mechanism 8. Each rod positioning component 81 includes a positioning frame 811 fixedly installed on the frame 1. A positioning seat 812 is fixedly installed on the outer wall of the top of the positioning frame 811. A plug is provided on the outer wall of one side of the positioning seat 812 for maintaining insertion with the ball head connecting rod 31 and the Y-type connecting rod 32. A positioning cylinder 813 is fixedly installed on the inner wall of one side of the positioning frame 811. An abutment seat 814 is fixedly installed at the output end of the positioning cylinder 813. The ball head connecting rod 31 and the Y-type connecting rod 32 can be moved into the positioning seat 812 by the second moving mechanism 6, and the abutment seat 814 is driven by the positioning cylinder 813 to maintain abutment with one end of the ball head connecting rod 31 and the Y-type connecting rod 32.

[0076] A first moving mechanism 5 is provided on the outer wall of one side of the frame 1. The first moving mechanism 5 includes a first moving module 51 and a first lifting module 52, such as... Figure 16 As shown, the first moving mechanism 5 is fixedly installed on the outer wall of one side of the frame 1. The first lifting module 52 is set at the output end of the first moving module 51. The first moving module 51 can drive the first lifting module 52 to maintain horizontal movement. The output end of the first lifting module 52 is provided with a first clamping claw 53. Preferably, there are two first clamping claws 53, and the first clamping claw 53 is specifically a cylinder clamping claw, which can be used to clamp the ball head connecting rod 31 and the Y-type connecting rod 32. The first lifting module 52 can drive the first clamping claw 53 to maintain vertical movement. The first moving module 51 can drive the first lifting module 52 to move between the loading station and the misaligned tightening station, and can move the ball head connecting rod 31 and the Y-type connecting rod 32 from the loading station to the misaligned tightening station.

[0077] A second moving mechanism 6 is also provided on the frame 1. The second moving mechanism 6 includes a second moving module 62 and a second lifting module 63. The second moving module 62 is fixedly installed on the outer wall of one side of the frame 1. The second lifting module 63 is located at the output end of the second moving module 62. The output end of the second moving module 62 can drive the second lifting module 63 to maintain horizontal reciprocating motion. A transfer frame 61 is fixedly installed at the output end of the second lifting module 63. The output end of the second lifting module 63 can drive the transfer frame 61 to maintain vertical lifting motion. The transfer frame 61 is provided with several sets of second gripping claws 482, such as... Figure 16 As shown, there are eight second clamping claws 482, with each pair of second clamping claws 482 forming a group, and they are arrayed on the transfer frame 61. The second clamping claws 482 on one side are used to clamp the ball head connecting rod 31, and the second clamping claws 482 on the other side are used to clamp the Y-shaped connecting rod 32.

[0078] The feeding mechanism 2 also includes a guide rail and a reciprocating motion unit 23. Both the guide rail and the reciprocating motion unit 23 are mounted on the frame 1. Several support members 22 are provided on the outer wall of one side of the feeding rack 21. Support grooves are provided on the outer walls of the support members 22. The support members 22 are arranged in a rectangular array on the outer wall of the feeding rack 21. Ball-head connecting rods 31 and Y-shaped connecting rods 32 are both located inside the support grooves. As an embodiment provided by the present invention, the reciprocating motion unit 23 is specifically a telescopic cylinder. The feeding rack 21 is slidably connected to the guide rail. The output end of the reciprocating motion unit 23 is connected to the feeding rack 21. Maintaining reciprocating motion through the output end of the reciprocating motion unit 23 can drive the feeding rack 21 to maintain reciprocating motion on the frame 1. Figure 15 As shown, the feeding rack 21 has a first feeding position and a second feeding position on the frame 1. The first feeding position is close to the first moving mechanism 5, and the second feeding position is far away from the first moving mechanism 5. The operator uses the straightening mechanism 9 to straighten the ball head connecting rod 31, and then manually places the ball head connecting rod 31 and the Y-shaped connecting rod 32 onto the support groove. The reciprocating motion unit 23 drives the feeding rack 21 to move between the first feeding position and the second feeding position. When the feeding rack 21 moves to the first feeding position, the operator is positioned on the side close to the straightening mechanism 9 to place the ball head connecting rod 31 and the Y-shaped connecting rod 32.

[0079] Specifically, in the prior art, the steering rod connector includes a ball joint connecting rod 31 and a Y-type connecting rod 32. The ball joint connecting rod 31 has a ball head inside. Before connecting the ball joint connecting rod 31 and the Y-type connecting rod 32, the ball head inside the ball joint connecting rod 31 needs to be aligned so that the axis of the hole inside the ball head is concentric with the axis of one end of the ball joint connecting rod 31. This alignment is achieved by a alignment mechanism 9. Figure 15As shown, the correction mechanism 9 is located on one side of the frame 1. The correction mechanism 9 includes a clamping seat 91 and a telescopic drive unit 92, as shown. Figure 15 As shown, the telescopic drive unit 92 is fixedly connected to the outer wall of one side of the frame 1. In an embodiment provided by the present invention, the telescopic drive unit 92 is specifically a telescopic cylinder. A connector rod 94 is fixedly installed at the output end of the telescopic drive unit 92. One end of the connector rod 94 has a frustum-shaped structure. The clamping seat 91 is fixedly disposed on the outer wall of one side of the frame 1. Figure 15 As shown, a positioning groove 93 for engaging one end of the ball head connecting rod 31 is provided on the outer wall of one side of the clamping seat 91. By engaging one end of the ball head connecting rod 31 in the positioning groove 93, the telescopic drive unit 92 drives the insertion rod 94 to maintain reciprocating motion. When the insertion rod 94 is inserted into the ball head connecting rod 31, the frustum-shaped insertion rod 94 can abut against the ball head inside the ball head connecting rod 31, thereby causing the ball head to rotate, thus ensuring that the ball head and the axis of one end of the ball head connecting rod 31 are coaxial.

[0080] It also includes a scribing mechanism 11 disposed on one side of the frame 1. The scribing mechanism 11 has a scribing station and includes a scribing frame 111 and a scribing positioning mechanism 112, such as Figure 13 and Figure 14 As shown, a marking cylinder 113 is fixedly installed on the outer wall of one side of the marking frame 111. A marking gripper cylinder 114 is installed at the output end of the marking cylinder 113. A marker pen is movably installed at the output end of the marking gripper cylinder 114. After the connection is completed, the connecting rod is moved to the marking positioning mechanism 112 through the second moving mechanism 6. Then, the marking cylinder 113 drives the marking gripper cylinder 114 to move towards the connecting rod, so that the tip of the marking pen keeps in contact with the nut post. Then, the marking gripper cylinder 114 drives the two marker pens to move away from each other, marking the nut post and the tightened nut.

[0081] It also includes a discharge rack 13 set on the frame 1. The discharge rack 13 is specifically a mechanical mechanism or device with material conveying, such as a conveyor belt. As an embodiment provided by the present invention, the discharge rack 13 is an inclined discharge plate, which can support the connected rods to facilitate material discharge.

[0082] Working principle:

[0083] First, the operator straightens the ball head inside the ball head connecting rod 31 using the straightening mechanism 9, and places the ball head connecting rod 31 and the Y-type connecting rod 32 onto the feeding rack 21. The support member 22 then supports the ball head connecting rod 31 and the Y-type connecting rod 32 on the feeding rack 21.

[0084] Then, the first moving module 51 of the first moving mechanism 5 drives the first lifting module 52 to move above the feeding rack 21. Then, the first lifting module 52 drives the first clamping claw 53 to descend and clamp a ball head connecting rod 31 and a Y-type connecting rod 32 respectively. Then, the ball head connecting rod 31 and the Y-type connecting rod 32 are transferred to the misaligned nut connection station by the first moving mechanism 5.

[0085] At the misaligned nut connection station, two tightened nuts are connected to the ball joint connecting rod 31 and the Y-type connecting rod 32 respectively by the misaligned nut connection mechanism 4. The ball joint connecting rod 31 and the Y-type connecting rod 32 are placed on the two sliding seats 41 by the first moving mechanism 5. The vibrating plate 451 of the feeding mechanism 45 transports the tightened nuts to the positioning frame 453 through the conveying track 452. The linear drive unit drives the sliding table 47 to keep moving on the fixed seat 46, so that the connecting sleeve 484 of the tightening mechanism 48 is aligned with the feeding hole 455 on the positioning frame 453. The output end of the clamping claw 482 drives the limiting block 483 to open. Then, the telescopic drive component drives the push rod 454 to move, so that one end of the push rod 454 abuts against the tightened nut, thereby moving the single tightened nut to the connection. The clamping claw 482 is then reset at the output end of the sleeve 484. The clamping nut is then restricted to the inside of the groove by the limiting block 483. Then, the limiting seat 411, which is slidably set on one of the sliding seats 41, is kept sliding by the sliding drive cylinder, so that the ball head connecting rod 31 and the Y-type connecting rod 32 are misaligned and separated. Then, the two sliding drive units 421 drive the two sliding seats 41 to move towards the two fixed seats 46 respectively, so that one end of the ball head connecting rod 31 and the Y-type connecting rod 32 is inserted into the connecting sleeve 484 of the two tightening mechanisms 48 respectively. Then, the connecting sleeve 484 is driven to rotate by the rotation drive unit 481, so that the two clamping nuts are connected to the ball head connecting rod 31 and the Y-type connecting rod 32 respectively. After the connection is completed, the sliding seat 41 and one of the limiting seats 411 are reset.

[0086] The second moving module 62 of the second moving mechanism 6 moves one end of the second lifting module 63 above the misaligned nut connecting mechanism 4. The second lifting module 63 drives the transfer frame 61 to descend. The second clamping claw 64 of the second lifting module 63 grabs the ball head connecting rod 31 and Y-shaped connecting rod 32 on the misaligned nut connecting station and transfers them to the nut column connecting station.

[0087] At the nut column connection station, the nut column is connected to the ball joint connecting rod 31 and the Y-shaped connecting rod 32 by the nut tightening mechanism 7. The second lifting module 63 drives the second clamping claw 64 to descend, so that the ball joint connecting rod 31 and the Y-shaped connecting rod 32 held by one set of second clamping claws 64 can be inserted into the insertion slot 74 of the support plate 73. The two ends of the ball joint connecting rod 31 and the Y-shaped connecting rod 32 are respectively connected to the positioning mechanism 77. The nut column supply mechanism 10 drives the unloading block 103 to move by the unloading cylinder 104 on the unloading rack 101, outputting a nut column. The lifting cylinder 106 drives the nut column cylinder clamp 107 to move and clamp the nut column. Then the lifting cylinder 106 resets, and the moving stage 105 is driven by the moving drive unit 110. The movement mechanism 775 then drives the two positioning mechanisms 77 to separate, causing the ball joint connecting rod 31 and the Y-type connecting rod 32 to separate. Subsequently, the lifting cylinder 106 inserts the nut column held by the nut column clamping cylinder 107 into the insertion slot 74 of the support plate 73. Then, the clamping mechanism 71 clamps the nut column, and the movement mechanism 775 drives the two positioning mechanisms 77 to move towards the nut column, thereby keeping the ball joint connecting rod 31 and the Y-type connecting rod 32 connected to the nut column. Then, the rotating mechanism 72 drives the clamping mechanism 71 to rotate, connecting the nut column and the ball joint connecting rod 31 and the Y-type connecting rod 32. After the connection is completed, the second moving mechanism 6 transfers the ball joint connecting rod 31 and the Y-type connecting rod 32 from the nut column tightening station to the nut tightening station.

[0088] At the nut tightening station, the two tightening nuts on the ball-head connecting rod 31 and the Y-type connecting rod 32 are connected to both ends of the nut column through the nut tightening mechanism 8, such as... Figure 15 and Figure 16 As shown, the two ends of the ball-head connecting rod 31 and the Y-shaped connecting rod 32 are respectively inserted into the rod positioning assembly 81 by the second moving mechanism 6, and the nut is tightened by the nut tightening mechanism 8. Since the nut tightening mechanism 8 includes a rotating mechanism 72 and a clamping mechanism 71, its specific structure and working principle will not be described in detail here. Then, the steering rod that has completed the connection at the nut tightening station is advanced to a station by the second moving mechanism 6.

[0089] At the marking station, the tightened nuts are marked by the marking mechanism 11, and then the marked steering rod is transferred to the discharge rack 13 by the second moving mechanism 6.

[0090] Those skilled in the art will understand that other similar connection methods can also achieve the present invention. For example, welding, bonding, or screwing.

[0091] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
