Detailed Implementation

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0036] Please refer to Figure 1-12 ;

[0037] The integrated machine described in this invention can automatically engage the tension spring body 24 with the pull rod body 22 and the base body 21, respectively, achieving automated production and improving production efficiency. The final product produced by this invention is one component of a rocker arm. The specific structure of this product is described below, including the pull rod body 22, the base body 21, and the tension spring body 24. The pull rod body 22 and the base body 21 are connected by a pin body 23 to allow them to rotate. The two end connecting portions 25 of the tension spring body 24 are respectively connected to the pull rod body 22 and the base body 21. 1. Connection: The base body 21 is also provided with an abutment part 28. After the tension spring body 24 is installed, under the tension of the tension spring body 24, the pull rod body 22 abuts against the abutment part 28. The abutment part 28 restricts the initial position of the pull rod body 22 and the base body 21. In addition, the two connecting parts 25 of the tension spring body 24 are not set at the same horizontal level. For example, the connecting parts 25 are circular. One of the connecting parts 25 is set horizontally, while the other connecting part 25 is tilted at a certain angle relative to the first connecting part 25. When the tilt reaches 90°, the two connecting parts 25 are perpendicular to each other.

[0038] The integrated machine of the present invention specifically includes a workbench 11, on which a conveying device 12 for moving the fixture 13 is installed. In this embodiment, the conveying device 12 can be a turntable device, which can reduce the volume occupied by the equipment. The following are installed sequentially along the running direction of the conveying device 12:

[0039] The base loading device 3 is used to place the base body 21 in the fixture 13. The base body 21 is provided with a fastening position 26 that is connected to the tension spring body 24.

[0040] The pull rod feeding device 4 is used to stack the pull rod body 22 on top of the base body 21. The pull rod body 22 is provided with a second fastening position 27 connected to the tension spring body 24. In this embodiment, the first fastening position 26 and the second fastening position 27 are staggered. In this embodiment, the first fastening position 26 includes a protrusion and a slot 1 is provided on the outside of the protrusion. The slot 1 is horizontally arranged. The second fastening position 27 includes a protrusion and a slot 2 is provided on the outside of the protrusion. The slot 2 is vertically arranged. The first slot and the second slot are staggered.

[0041] The pin feeding device 5 is used to pass the pin body 23 through the tie rod body 22 and the base body 21, so that the two are rotatably connected with the pin as the fulcrum. First, the position of the base body 21 and the tie rod body 22 is defined by the fixture 13. Both the base body 21 and the tie rod body 22 are provided with through holes for the pin to pass through. After being defined by the fixture 13, the two through holes correspond to each other, so that the pin can be easily inserted into the through holes. In another embodiment, a positioning post with a through hole can be set at the through hole of the base body 21. When the tie rod body 22 is assembled on top of the base body 21, the positioning post can enter the through hole of the tie rod body 22, which can play a preliminary fixing role, and the pin body 23 can be inserted into the through hole of the positioning post. Regardless of whether the positioning post is present, the base body 21 and the tie rod body 22 should rotate relative to each other with the pin body 23 as the fulcrum.

[0042] The riveting device 6 is used to rivet and fix the pin body 23.

[0043] The tension spring feeding device 7 is used to drive the tension spring body 24 to rotate at a certain angle so that one end of the tension spring body 24 is connected to the first fastening position 26 / the second fastening position 27, and the two ends of the tension spring body 24 are staggered.

[0044] The tension spring fastening device 8 is used to connect the other end of the tension spring body 24 to the fastening position 27 / fastening position 26.

[0045] It should be noted that the installation sequence of the tension spring body 24 can be such that one of the connecting parts 25 is connected to the first fastening position 26 or the second fastening position 27 first, and the other connecting part 25 is connected to the first fastening position 26 or the second fastening position 27 second, so the connection sequence is not limited; the following example illustrates the sequence of the tension spring body 24 being connected to the first fastening position 26 first and then to the second fastening position 27 second.

[0046] First, the jig 13 is transported to the corresponding positions of the base loading device 3, the pull rod loading device 4, the pin loading device 5, and the riveting device 6 via the conveying device 12. The base body 21 and the pull rod body 22 are stacked together in sequence via the above devices. Then, the pin body 23 is passed through the two. Finally, the pin body 23 is fixed by the riveting device 6, so that the base body 21 and the pull rod body 22 are in a rotatable state, and the initial assembly is completed.

[0047] Then, the conveying device 12 drives the fixture 13 to the position corresponding to the tension spring feeding device 7. The tension spring feeding device 7 extends the tension spring body 24 toward the fixture 13, so that the connecting part 25 is located outside the first fastening position 26. Then, the tension spring feeding device 7 moves again, causing the connecting part 25 to move closer to the first fastening position 26. At the same time, it drives the tension spring body 24 to rotate. The connecting part 25 follows the rotation of the tension spring body 24, so that it is sleeved on the first fastening position 26. That is, the connecting part 25 is circular. During the rotation, the first protrusion enters into the circle of the connecting part 25, and the connecting part 25 is also locked into the first slot. Afterwards, the fixture 13 is moved to the position corresponding to the tension spring fastening device 8 by the conveying device 12. The other connecting part 25 of the tension spring body 24 is connected to the second fastening position 27 through the tension spring fastening device 8, completing the overall installation.

[0048] The integrated machine described in this invention enables the installation of the tension spring body 24 on the base body 21 and the pull rod body 22, achieving fully automated production and improving production efficiency.

[0049] One embodiment of the present invention relates to the tension spring feeding device 7, see reference to Figures 5-8 Specifically, it includes a tension spring conveying assembly 41, a tension spring pushing assembly 42, and a tension spring transfer assembly 43 that moves back and forth between the two. In this embodiment, the tension spring pushing assembly 42 is used to drive the tension spring body 24 to rotate, so that one of the connecting parts 25 is connected to the fastening position 26. Usually, the rotation angle of the tension spring pushing assembly 42 is fixed, so the initial angle of the tension spring body 24 needs to be aligned in advance. Therefore, a tension spring alignment assembly 44 is installed at the output end of the tension spring conveying assembly 41.

[0050] Furthermore, the tension spring conveying assembly 41 typically employs a combination of a conveying channel and a vibratory feeder. The vibratory feeder causes the tension spring bodies 24 to sequentially enter the channel. However, the swing angle of the tension spring bodies 24 within the channel is uncertain. Therefore, a tension spring aligning assembly 44 is installed at the output end of the tension spring conveying assembly 41 to adjust the angle of the tension spring bodies 24 that are about to be output. Specifically, refer to... Figure 7 and Figure 8The tension spring straightening assembly 44 includes a fixing block 441 and a cylinder 442. The fixing block 441 has a channel 443 corresponding to the output end of the tension spring conveying assembly 41. The shape of the channel 443 is adapted to the shape of the tension spring body 24. The output end of the cylinder 442 is connected to a straightening rod 444. The straightening rod 444 passes through the fixing block 441 and is perpendicular to the channel 443. The side of the straightening rod 444 occupies less than half of the cross-sectional area of ​​the channel 443. It should be noted that the tension spring body 24 in this embodiment is cylindrical. Although the connecting parts 25 at both ends are staggered, they are all located in the middle of the ends of the tension spring body 24. For the cross-sectional area of ​​the channel 443, the connecting parts 25 occupy the middle part, so the side of the straightening rod 444 occupies less than half of the cross-sectional area of ​​the channel 443.

[0051] When working, refer to Figures 7-9 Under the action of the tension spring conveying assembly 41, several tension spring bodies 24 are gradually pushed towards the tension spring straightening assembly 44. When the foremost tension spring body 24 enters a certain position in the channel 443, the tilt state of the connecting part 25 of the tension spring body 24 does not need to be considered. Assuming that the connecting part 25 is in a vertical state at this time, the cylinder 442 pushes the straightening rod 444 to extend laterally relative to the channel 443. When the straightening rod 444 passes laterally through the channel 443, its end abuts against the vertical connecting part 25. As the straightening rod 444 continues to extend, it will push the connecting part 25, causing the entire tension spring body 24 to rotate. Finally, the tension spring body 24 rotates 90°, and the connecting part 25 changes from a vertical state to a horizontal state. At this time, the straightening rod 444 hinders the advancement of the tension spring body 24. The cylinder 442 drives the straightening rod 444 to retract, so that the next tension spring body 24 can push the previous tension spring body 24, which has been angled, to advance.

[0052] It should be noted that the forward speed of the tension spring body 24 transported by the vibratory feeder is relatively slow, and there is a brief pause when the tension spring transfer assembly 43 picks up the tension spring body 24 output from the fixed block 441. This pause hinders the forward movement of the tension spring body 24. In conjunction with the detection assembly 45 used to detect whether the tension spring body 24 is output from the fixed block 441, when the detection assembly 45 detects that the aligned tension spring body 24 has extended from the fixed block 441, it sends a signal to the controller. That is, at the instant the detection device detects the extension of the tension spring body 24, the tension spring transfer assembly 43 simultaneously moves to transfer the tension spring body... When the spring body 24 is clamped, it will be obstructed and stop moving forward in the channel 443. At the same time, the cylinder 442 pushes the straightening rod 444 to straighten the next spring body 24 and block its forward movement. Then, under the drive of the spring transfer component 43, the spring body 24 is transferred to the corresponding position of the spring push component 42 and is picked up by the spring push component 42. After the spring body 24 is transferred and reset, the cylinder 442 drives the straightening rod 444 to be pulled out of the channel 443, so that the next spring body 24 can move forward and output, and so on.

[0053] Reference Figure 6 In this embodiment, the tension spring transfer assembly 43 includes a multi-axis moving component 431. A pneumatic gripper 432 is installed at the moving end of the multi-axis moving component 431. The pneumatic gripper 432 can prevent angular displacement during the transfer of the tension spring body 24 by clamping it. Of course, the pneumatic gripper clamps the tension spring body 24, not the connecting part 25.

[0054] One embodiment of the present invention relates to the tension spring push assembly 42, see reference to Figure 6 , Figures 2-4 Specifically, it includes a multi-axis moving component 421, the moving end of which is connected to a rotating component 422, and the output end of the rotating component 422 is connected to a pneumatic gripper 423. When the tension spring transfer assembly 43 transfers the tension spring body 24, which has been adjusted to the correct angle, to the corresponding position of the tension spring pushing assembly 42, the multi-axis moving component 421 moves the pneumatic gripper 423 closer to the tension spring transfer assembly 43, and the pneumatic gripper 423 clamps the tension spring body 24. After the tension spring transfer assembly 43 resets, the multi-axis moving component 421... The pneumatic gripper 423 is moved toward the fixture 13, so that one of the connecting parts 25 of the tension spring body 24 is located outside the snap-fit ​​position. At this time, after the angle of the tension spring body 24 is adjusted, the connecting part 25 corresponding to the snap-fit ​​position 26 is in a horizontal state. Then, the multi-axis moving component 421 moves slightly laterally toward the snap-fit ​​position 26. At the same time, the rotating component 422 is activated, causing the pneumatic gripper 423 to rotate 180°, so that the snap-fit ​​position 26 passes through the connecting part 25, and the connecting part 25 completes the connection with the snap-fit ​​position 26.

[0055] It should be noted that the pneumatic gripper 423 and pneumatic gripper 432 described in this invention should include a clamping arm provided at the output end. This clamping arm can be obtained from the prior art and will not be described in detail here.

[0056] After the tension spring body 24 is connected to the first fastening position 26, it still has a certain distance from the second fastening position 27. Therefore, the tension spring fastening device 8 in this embodiment includes a prying component for pushing the tension spring body 24 to move laterally, and a pressing component for connecting the other end of the tension spring body 24 to the second fastening position 27 / the first fastening position 26. (Refer to...) Figures 10-12 Based on the above embodiment, one of the connecting parts 25 of the tension spring body 24 is first connected to the first fastening position 26. Therefore, the pressing component should be set to correspond to the second fastening position 27. During operation, the tension spring body 24 is moved laterally by the actuating component to move it closer to the pull rod body 22, and the other connecting part 25 is brought close to the second fastening position 27. In this embodiment, the connecting part 25 is circular. At this time, the connecting part 25 corresponding to the second fastening position 27 is at 90° relative to the connecting part 25 corresponding to the first fastening position 26. The second fastening position 27 corresponds to the hollow position of the connecting part 25. Then, the pressing component extends to press the other connecting part 25 towards the second fastening position 27, so that the second fastening position 27 is completely inserted into the hollow position of the connecting part 25, thereby achieving a fixed connection.

[0057] Furthermore, the actuating assembly includes a second cylinder 811, a fixed seat 812 is mounted on the output end of the second cylinder 811, a third cylinder 813 is mounted on one side of the fixed seat 812, and an actuating plate 814 is mounted on the output end of the third cylinder 813. The actuating plate 814 is slidably connected to the fixed seat 812, and one side of the lower end of the actuating plate 814 corresponds to the tension spring body 24. The actuating plate 814 pushes the tension spring body 24 to move towards the pull rod body 22. After one of the connecting parts 25 of the tension spring body 24 is connected to the first fastening position 26, the state of the tension spring body 24 is the same as... The relative positions of the pull rod body 22 are nearly parallel. The fixed seat 812 is driven to descend by the second cylinder 811. At the same time, the actuating plate 814 and the third cylinder 813 descend, so that the actuating plate 814 is located on one side of the tension spring body 24. Then, the third cylinder 813 pushes the actuating plate 814 to move laterally. The actuating plate 814 pushes the tension spring body 24 to rotate around the first buckle position 26. The rotation angle of the tension spring body 24 is less than 90°, so that it rotates towards the pull rod body 22, and finally makes the other connecting part 25 fit tightly with the second buckle position 27.

[0058] Furthermore, the pressing assembly includes a pushing component 821, the output end of which is connected to a movable seat 822. The movable seat 822 is provided with a pressing rod 823, and the pressing rod 823 is provided with a notch 824 for accommodating the second fastening position 27 / the first fastening position 26. Based on the above embodiment, the pressing rod 823 should correspond to the position of the first fastening position 26, and a pressing part 825 is formed on at least one side of the notch 824. The pressing part 825 corresponds to the connecting part 25 of the tension spring body 24. After the other connecting part 25 is pressed against the second fastening position 27, an external force needs to be applied to the connecting part 25 to press it into the second fastening position 27 so that the second fastening position 27 can pass through the connecting part 25 to complete the fixation.

[0059] During operation, the pusher 821 moves the pressure rod 823 toward the pull rod body 22. The notch 824 of the pressure rod 823 corresponds to the second fastening position 27. When it reaches a certain position, the pressing part 825 located on the side of the notch 824 corresponds to the connecting part 25 located outside the second fastening position 27. As the pusher continues to extend, the pressing part 825 applies a pushing force to the connecting part 25, thereby pushing the connecting part 25 forward. The second fastening position 27 enters the notch 824 and passes through the connecting part 25, thus fixing the connecting part 25 and the second fastening position 27.

[0060] Based on all the above embodiments, a corresponding detection device should be provided between each processing device to detect whether each part is installed in place. In addition, a feeding device is provided to remove the assembled product from the fixture 13. The detection method and the feeding device are both existing technologies and will not be described in detail here.
