[0021] like Figure 1 and Figure 7 As shown, a mounting plate 2 is provided on the frame 1. Specifically, the mounting plate 2 is vertically mounted on the outer wall of the frame 1. A drive wheel 3 is rotatably mounted on one side of the outer wall of the mounting plate 2. A first slot 31 is provided on the top of the drive wheel 3. Specifically, the inner wall of the first slot 31 has a "U"-shaped structure, which facilitates the insertion of a connecting rod into the first slot 31. Preferably, one end of the first slot 31 is located at the center of the drive wheel 3, so that the inserted connecting rod is concentric with the drive wheel 3. A drive plate 4 is movably mounted on one side of the outer wall of the mounting plate 2. A clamping plate 41 is movably mounted on the drive plate 4. Specifically, the clamping plate 41 is slidably connected to the drive wheel 3. A second slot 42 is provided on one side of the outer wall of the drive plate 4. Preferably, the second slot 42 is connected to the first drive wheel 3. The shape of the slot 31 is adapted so that the connecting rod can be connected to the mounting plate 2 and the drive piece 4 through the first slot 31 and the second slot 42. A drive mechanism 5 is provided on the outer wall of one side of the mounting plate 2. The drive mechanism 5 is connected to the drive wheel 3. The drive wheel 3 is driven to rotate by the drive mechanism 5. The steering rod connector can be inserted into the first slot 31, the second slot 42 and the third slot 21, so that the steering rod connector is connected to the mounting plate 2. The clamping piece 41 can be clamped by the drive piece 4. The drive wheel 3 is driven to rotate by the drive mechanism 5 so that the clamping piece 41, which is slidably connected to it, can rotate synchronously, so that the positive and negative nut sleeves can be rotated, and thus the positive and negative nut sleeves can be connected to the connecting rod.

[0022] This invention allows the connecting rod to be inserted into the mounting plate 2 via a first slot 31 on the drive wheel 3, a second slot 42 on the drive plate 4, and a third slot 21 on the mounting plate 2. The drive plate 4 on the mounting plate 2 drives the clamping plate 41 to clamp the positive and negative nut sleeves, and the drive wheel 3 on the mounting plate 2 drives the clamping plate 41 to rotate, connecting the connecting rod and the positive and negative nut sleeves.

Furthermore, a plug-in groove 23 is provided on the outer wall of one side of the connecting post 22. A plug-in driving component 24 is fixedly installed on the outer wall of one side of the mounting plate 2.

The output end of the plug-in driving component 24 is adapted to the shape of the plug-in groove 23. The output end of the plug-in driving component 24 can be driven to keep plugged into the plug-in groove 23, thereby limiting the stroke of the driving plate 4.

[0024] Furthermore, a reciprocating drive unit 25 is fixedly installed on the outer wall of one side of the mounting plate 2. A through hole is provided on the outer wall of one side of the mounting plate 2, and the output end of the reciprocating drive unit 25 passes through the through hole and is connected to the drive plate 4.

When the first bevel gear 521 is driven by the drive unit 51... The rotation of the first drive wheel 541, which is coaxial with the second drive wheel 541, is maintained in rotation. The rotation of the first drive wheel 541 drives the transmission belt, which in turn drives the second drive wheel 542 and the third drive wheel 543 to rotate. This, in turn, drives the two drive wheels 53 to rotate. In an embodiment of the invention, there are three driven wheels 55 arranged in a circular array on the outer wall of the mounting plate 2.

The rotating sleeve 102 is coaxial with the output end of the rotating unit 104. A receiving groove for accommodating the tightening nut is provided on the outer wall of one side of the rotating sleeve 102. A push-out drive unit 115 is provided on the outer wall of one side of the sliding seat 101. A push-out plate 116 is fixedly installed on the output end of the push-out drive unit 115. A push-out rod 117 is fixedly installed on the outer wall of the push-out plate 116. By keeping the output end of the push-out drive unit 115 in motion, the push-out plate 116 can drive the push-out rod 117 to keep moving. Preferably, the installation position of the push-out rod 117 is adapted to the position of the feeding hole 114 on the mounting frame 113, so that the tightening nut in the feeding hole 114 in the mounting frame 113 can be pushed out of the mounting frame 113 by the movement of the push-out rod 117. As an embodiment provided by the present invention, the rotating unit 104 is a servo motor, and the push-out drive unit 115 and the horizontal drive unit 107 are specifically telescopic cylinders.

[0033] The horizontal drive unit 107 drives the sliding seat 101 to slide on the mounting base 106, which aligns the rotating sleeve 102 on the gripper cylinder 105 with the feed hole 114 on the mounting frame 113. Then, the push-out drive unit 115 drives the push plate 116 to move, thereby pushing the push rod 117 to push the tightening nut in the mounting frame 113 into the receiving groove of the rotating sleeve 102. The limiting block installed at the output end of the gripper cylinder 105 limits the tightening nut inside the rotating sleeve 102 to prevent it from falling out of the receiving groove. Finally, the horizontal drive unit 107 drives the sliding seat 101 to reset.

[0034] The connecting rod fixing mechanism 9 includes a horizontal moving unit 91 and a positioning plug block 92 disposed on the sliding frame 8. Specifically, the horizontal moving unit 91 is fixedly disposed on the outer wall of one side of the frame 1, and the sliding frame 8 is disposed at the output end of the horizontal moving unit 91. The horizontal moving unit 91 can drive the sliding frame 8 to maintain reciprocating motion on the slide rail.

[0035] As a further embodiment of the present invention, one of the sliding frames 8 is slidably disposed on the output end of one of the horizontal moving units 91. A reciprocating moving unit 911 is provided on the outer wall of the output end of one of the horizontal moving units 91. The output end of the reciprocating moving unit 911 is fixedly connected to one of the sliding frames 8. The output end of the reciprocating moving unit 911 can drive one of the sliding frames 8 to maintain reciprocating motion, thereby causing the connecting rod inside the connecting rod fixing mechanism 9 on one of the sliding frames 8 to be misaligned with the other sliding frame 8, preventing the two sliding frames 8 from interfering when maintaining opposite movements.

[0036] A positioning clamping block 93 is provided on the outer wall of one side of the sliding frame 8. Specifically, the positioning clamping block 93 has a clamping groove that matches the connecting rod body, which can clamp the connecting rod. The sliding frame 8 is driven to move on the frame 1 by the horizontal moving unit 91, and one end of the connecting rod connected to the positioning clamping block 93 can be moved toward the tightening mechanism 10, so that one end of the connecting rod can be inserted into the rotating sleeve 102.

[0037] A wedge-shaped rod 94 is fixedly installed on the outer wall of one side of the positioning plug-in block 92. One end of the wedge-shaped rod 94 can be plugged into one end of the connecting rod to prevent the wedge-shaped rod 94 from rotating in the positioning clamping block 93.

[0038] Furthermore, the connecting rod fixing mechanism 9 also includes a limiting mechanism 95, which includes a limiting frame 951, a positioning ball 953 rotatably mounted on the limiting frame 951, and a telescopic drive unit 952 mounted on the limiting frame 951. Specifically, the limiting frame 951 is fixedly installed on the outer wall of one side of the sliding frame 8. A rod is provided on the outer wall of the positioning ball 953, and the positioning ball 953 is rotatably connected to the limiting frame 951 through the rod. The telescopic drive unit 952 is fixedly installed on the outer wall of one side of the limiting frame 951, and the output end of the telescopic drive unit 952 is rotatably connected to the rod of the positioning ball 953. Thus, the output end of the telescopic drive unit 952 can drive the positioning ball 953 to rotate around the connection point with the limiting frame 951, thereby keeping the positioning ball 953 in contact with the outer wall of the connecting rod and fixing the connecting rod in the positioning clamping block 93.

[0039] Working principle: Place the two connecting rods that need to be connected onto the sliding frame 8, so that the connecting rods are mounted on the sliding frame 8 through the connecting rod fixing mechanism 9; The feeding mechanism 11 conveys the material to the mounting frame 113 via the vibratory feeder 111 and guide rail 112. The horizontal drive unit 107 drives the sliding seat 101 to slide on the mounting seat 106, so that the rotating sleeve 102 is aligned with the feeding hole 114 opened on the mounting frame 113. The push-out drive unit 115 drives the push-out rod 117 to move and insert into the feeding hole 114, pushing out a single tightened nut from the feeding hole 114 and into the rotating sleeve 102. Then the horizontal drive unit 107 drives the sliding seat 101 to reset. One of the sliding frames 8 is driven to slide by the reciprocating moving unit 911 so that the two connecting rods are misaligned and separated. Then, one end of the connecting rod is inserted into the tightening mechanism 10 on the opposite side by the horizontal moving unit 91, and the tightening mechanism 10 connects the tightening nut to the connecting rod. After the connection is completed, the connecting rod is transferred to the mounting plate 2 by manual or robotic means. The connecting rod is inserted into the mounting plate 2 through the positioning seats 6 on both sides of the mounting plate 2 and the third slot 21 opened on the mounting plate 2, and the two connecting rods are erected by the positioning seats 6 on both sides. The feeding block 72 of the positive and negative nut sleeve supply mechanism 7 transports a single positive and negative nut sleeve out of the supply rack 71. The lifting unit 733 controls the gripper unit 734 to descend and grab a single positive and negative nut sleeve. Then, the moving drive unit 731 transfers the positive and negative nut sleeve to the mounting plate 2. The sliding drive unit 62 drives the positioning seat 6 to move away from the mounting plate 2, so that the two connecting rods are separated from each other. Then, the lifting unit 733 and the gripper unit 734 place a single positive and negative nut sleeve into the third slot 21 of the mounting plate 2. Subsequently, the reciprocating drive unit 25 drives the drive plate 4 to keep sliding, and drives the two clamping plates 41 to keep moving towards each other to clamp the positive and negative nut sleeve. The sliding drive unit 62 drives the positioning seat 6 to move toward the mounting plate 2, so that one end of each of the two connecting rods is inserted into the two ends of the positive and negative nut sleeves respectively; Subsequently, the drive mechanism 5 drives the drive wheel 3 to rotate, so that the positive and negative nut sleeves are threadedly connected to the two connecting rods.

[0040] Those skilled in the art will understand that other similar connection methods can also achieve the present invention. For example, welding, bonding, or screwing.

[0041] 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.
