DETAILED DESCRIPTION

[0025] The following is combined with Figure 1-8 This application is described in further detail.

[0026] A right angle bolt tightening device, referring to Figure 1 As shown, it includes a workbench 1, and a bolt feeding mechanism 2, a nut feeding mechanism 3, a bolt picking mechanism 4, a nut picking mechanism 5 and a rotary clamping mechanism 6 arranged on the workbench 1.

[0027] There is an installation station on the workbench 1, which is arranged in the middle position of the workbench 1. The bolt feeding mechanism 2 and the nut feeding mechanism 3 are both arranged on one side of the installation station. The nut picking mechanism 5 is arranged in the installation station for clamping the adjustment nut delivered by the nut feeding mechanism 3. The bolt picking mechanism 4 is arranged on the other side of the installation station for clamping the adjustment bolt delivered by the bolt feeding mechanism 2 to above the adjustment nut. The rotary clamping mechanism 6 is arranged above the nut picking mechanism 5 for clamping the adjustment bolt and tightening it on the adjustment nut.

[0028] In this embodiment, the adjusting bolt and the adjusting nut are used in the handrail of the lawn mower. The adjusting bolt has a bolt head and a bolt body. The bolt head is a disc-shaped protrusion, and the bolt body is a cylinder. The bolt body is provided with external threads, wherein a square rotating block is provided at the joint between the bolt head and the bolt body to facilitate rotation through the square rotating block. The adjusting nut has a cap body and a handle. The cap body is provided in the middle of the handle, and an internal threaded hole is provided on the cap body to facilitate threaded connection with the bolt body of the adjusting bolt.

[0029] The bolt feeding mechanism 2 , the nut feeding mechanism 3 , the bolt taking mechanism 4 , the nut taking mechanism 5 and the rotary clamping mechanism 6 are described in detail below.

[0030] Reference Figure 1 and Figure 3 As shown, the nut feeding mechanism 3 includes a nut vibrating plate 31, and a nut feeding track 32 arranged at the output port of the nut vibrating plate 31, and a nut limiting part for lifting and blocking the outlet of the nut feeding track 32 is arranged on the workbench 1. The nut limiting part includes a nut limiting baffle 34 and a nut lifting cylinder 35, the cylinder body of the nut lifting cylinder 35 is arranged on the workbench 1, the nut limiting baffle 34 is arranged on the output rod of the nut lifting cylinder 35, and the nut limiting baffle 34 blocks the outlet of the nut feeding track 32 under the drive of the nut lifting cylinder 35.

[0031] The nut feeding track 32 includes two nut track rods 321 arranged in parallel, and a nut track seat 322 is arranged above the two nut track rods 321. A receiving space for accommodating an adjusting bolt is formed between the nut track seat 322 and the nut track rod 321, wherein a cap body receiving groove 323 for accommodating an adjusting nut is arranged on the lower surface of the nut track seat 322 along its length direction, and a cap body clamping avoidance groove 33 is arranged at the opening of the nut track seat 322.

[0032] The adjusting nuts are placed in the nut vibration plate 31, and the nut vibration plate 31 adjusts the direction of the adjusting nuts and transports them in rows and parallel along the nut feeding track 32. The nut limit baffle 34 blocks the outlet of the nut feeding track 32, so that the adjusting nuts can be arrayed on the nut feeding track 32. When the adjusting nuts near the outlet of the nut feeding track 32 reach the position, the nut vibration plate 31 stops the feeding action, and the nut limit baffle 34 moves down under the drive of the nut lifting cylinder 35, so as to facilitate the subsequent nut picking mechanism 5 to clamp the adjusting nuts.

[0033] Reference Figure 4 and Figure 5 As shown, the nut picking mechanism 5 includes a nut picking cylinder 51 arranged on the workbench 1, and a nut clamping cylinder 52 arranged on the output rod of the nut picking cylinder 51. The nut picking cylinder 51 and the nut clamping cylinder 52 are both arranged in the horizontal direction. The nut clamping cylinder 52 is arranged toward the nut feeding mechanism 3. The clamping jaws of the nut clamping cylinder 52 are provided with a nut clamping groove 53 for adapting and adjusting the cap body of the nut.

[0034] The nut picking cylinder 51 drives the nut clamping cylinder 52 to extend, and the nut clamping cylinder 52 clamps the cap body of the adjusting nut, and then the nut picking cylinder 51 retracts, so that the nut clamping cylinder 52 clamps the adjusting nut and stays at the installation position of the workbench 1 to wait for the subsequent rotation and assembly of the adjusting bolt.

[0035] Reference Figure 1 and Figure 2 As shown, the bolt feeding mechanism 2 includes a bolt vibrating plate 21 and a bolt feeding track 22 arranged at the output port of the bolt vibrating plate 21. A bolt limiting part for lifting and blocking the outlet of the bolt feeding track 22 is arranged on the workbench 1. The bolt limiting part includes a bolt limiting baffle 24 and a bolt lifting cylinder 25. The cylinder body of the bolt lifting cylinder 25 is arranged on the workbench 1. The bolt limiting baffle 24 is arranged on the output rod of the bolt lifting cylinder 25. The bolt limiting baffle 24 blocks the outlet of the bolt feeding track 22 under the drive of the bolt lifting cylinder 25.

[0036] The bolt feeding track 22 includes two parallel bolt track pieces 221, a bolt body accommodating groove 222 is formed between the two bolt track pieces 221, the surfaces of the two bolt track pieces 221 are used to support the bolt head of the adjustment bolt, and a bolt body clamping avoidance groove 23 is opened at the outlet of the bolt track piece 221.

[0037] The adjusting bolts are placed in the bolt vibration plate 21. The bolt vibration plate 21 adjusts the direction of the adjusting bolts and then transports them in a suspended row along the bolt feeding track 22. The bolt limit baffle 24 blocks the exit of the bolt feeding track 22, so that the adjusting bolts can be arrayed on the bolt feeding track 22. When the adjusting bolts near the exit of the bolt feeding track 22 reach the position, the bolt vibration plate 21 stops the feeding action, and the bolt limit baffle 24 moves down under the drive of the bolt lifting cylinder 25 to facilitate the subsequent bolt picking mechanism 4 to clamp the adjusting bolts.

[0038] Reference Figure 6 and Figure 7 As shown, the bolt picking mechanism 4 includes a bolt picking cylinder 41 arranged on the workbench 1, and a bolt picking mounting seat 42 arranged on the output rod of the bolt picking cylinder 41, a bolt picking bidirectional cylinder 43 is arranged on the bolt picking mounting seat 42, and bolt picking clamping seats 44 are arranged on the two output rods of the bolt picking bidirectional cylinder 43, and each bolt picking clamping seat 44 is provided with a bolt clamping block 45, and the bolt clamping block 45 is arranged toward one side of the bolt feeding mechanism 2, and the two bolt clamping blocks 45 are matched to form a semicircle, and each bolt clamping block 45 is provided with a bolt body clamping groove 46.

[0039] As a result, the bolt picking cylinder 41 drives the bolt picking bidirectional cylinder 43 to move toward one side of the bolt feeding mechanism 2, and the bolt picking bidirectional cylinder 43 drives the bolt clamping block 45 to close together, and then clamps the bolt body of the adjusting bolt in the bolt feeding track 22, and then the bolt picking cylinder 41 retracts, and the adjusting bolt stops at the installation position of the workbench 1. At this time, since the adjusting bolt is clamped by two bolt clamping blocks 45, the bolt clamping blocks 45 are combined to form a semicircle, and the bolt clamping block 45 is in the shape of a slender strip, so that the bolt clamping block 45 can avoid the subsequent rotating clamping mechanism, and the rotating clamping mechanism can replace the bolt clamping block 45 to clamp the adjusting bolt at the installation position, and then rotate the adjusting bolt to the adjusting nut.

[0040] Reference Figure 4 and Figure 8 As shown, the rotary clamping mechanism 6 includes a rotary mounting bracket 61 arranged on the workbench 1, and a rotary clamping portion 62 arranged on the rotary mounting bracket 61, the rotary clamping portion 62 is used to clamp and rotate the adjustment bolt, and the rotary mounting bracket 61 is provided with a lifting drive portion 63 for driving the rotary clamping portion 62 to move up and down.

[0041] The rotating clamping part 62 includes a rotating mounting seat 621, a rotating drive motor 622 and a bolt rotating clamping claw cylinder 623 which are arranged in sequence. The rotating mounting seat 621 is arranged on the lifting drive part 63, the rotating drive motor 622 is fixedly arranged on the rotating mounting seat 621, the cylinder body of the bolt rotating clamping claw cylinder 623 is fixed on the output shaft of the rotating drive motor 622, and two clamping claws are arranged on the bolt rotating clamping claw cylinder 623.

[0042] The clamping claw includes a claw mounting block 624 and a clamping claw 625. The claw mounting block 624 is arranged on the bolt rotating claw cylinder 623. The clamping claw 625 is fixed on the claw mounting block 624. The clamping claw 625 is arranged in an L shape. A bolt head placement groove 626 is provided between the short side of the clamping claw 625 and the claw mounting block 624. The short side end face of the clamping claw 625 is arranged as a plane. A claw clamping block 627 is arranged on the short side end face of the clamping claw 625. An arc-shaped bolt body clamping groove is arranged on the claw clamping block 627. The arc-shaped bolt body clamping groove is used to clamp the bolt body of the adjusting bolt. The side wall of the square rotating block on the adjusting bolt will abut against the short side end face of the clamping claw 625.

[0043] The lifting drive unit 63 includes a lifting drive cylinder, the cylinder body of the lifting drive cylinder is fixed on the rotating mounting bracket 61, and the rotating mounting seat 621 is fixed on the output rod of the lifting drive cylinder. The lifting drive cylinder drives the rotating mounting seat 621 to perform up and down lifting actions.

[0044] Therefore, when the bolt picking mechanism 4 clamps the adjusting bolt and is located at the installation position, the lifting drive part 63 drives the rotating clamping part 62 to move downward, and clamps the adjusting bolt through the bolt rotating clamping claw cylinder 623. At this time, the bolt picking bidirectional cylinder 43 drives the bolt picking clamping seat 44 to move to loosen the clamping of the adjusting bolt.

[0045] At this time, the adjusting bolt and the adjusting nut are on the same vertical direction line, the lifting drive part 63 continues to drive the rotating clamping part 62 to move downward, aligning the bolt body of the adjusting bolt with the cap body of the adjusting nut, and the rotating drive motor 622 drives the bolt rotating claw cylinder 623 to rotate, thereby realizing the rotation of the adjusting bolt on the adjusting nut.

[0046] Among them, the number of turns of the adjusting bolt and the adjusting nut is only three to five turns, so the adjusting nut will not be displaced up and down significantly and get stuck.

[0047] It is worth mentioning that a receiving bin is also provided at the installation position of the workbench 1, and the receiving bin is located below the nut picking mechanism 5. When the adjusting bolt is rotated onto the adjusting nut, the nut picking mechanism 5 releases the clamping of the adjusting nut, and the bolt picking mechanism 4 releases the clamping of the adjusting bolt. Therefore, the matching adjusting bolt and adjusting nut will fall as a whole into the receiving bin for collection.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
