[0022] The above and other embodiments and advantages of the present invention are clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments.
[0023] In one embodiment, Figures 1-6 As shown:
[0024] This embodiment provides a quick installation device for terminal plug-ins, including a horizontal frame 1, a vertical frame 2 is fixed on the horizontal frame 1, a horizontal slot seat 3 is provided in the horizontal frame 1, the horizontal slot seat 3 brings the gasket and the plug-in into the bottom of the vertical frame 2 at the same time, a tool 5 is provided on the vertical frame 2, the horizontal slot seat 3 is provided with a top seat 6 below the tool 5, a heating body is provided in the top seat 6, the tool 5 includes a clamping device 9 and a second driving device, the top seat 6 passes through the gasket to push the plug-in into the clamping device 9 for clamping, and heats the inner ring of the gasket to expand, and the horizontal A first travel switch 7 is provided at the left and right travel position of the slot seat 3 relative to the tooling 5, and a second travel switch 8 is provided at the up and down travel position of the tooling 5 relative to the top seat 6. The second travel switch 8 is electrically connected to the clamping device 9 and the second drive device. The bottom of the top seat 6 is provided with a first drive device electrically connected to the first travel switch 7. The quick-install device of the terminal plug-in is also provided with a controller, which includes at least a timing module and a control module. The timing module is connected to the first travel switch 7 and the second travel switch 8 and is controlled by the control module.
[0025] like Figure 1 、 Figure 2As shown, the gasket B is placed in the transverse groove seat 3, and the plug-in C is placed above the gasket B. The inner ring size of the gasket B is smaller than the outer contour size of the plug-in C, and a tight fit is achieved after assembly. The gasket B and the plug-in C are synchronously transported to the bottom of the tooling 5 through the transverse groove seat 3, and above the station where the top seat 6 is located, and the moving end of the transverse groove seat 3 is precisely contacted with the first travel switch 7, which will produce the following technical effects: first, the third-party heating device is triggered to provide heat to the heating body in the top seat 6; second, the first driving device is triggered to push the top seat 6 through the inner ring of the gasket B, and the inner ring of the gasket B is instantly heated and expanded. After that, plug-in C is pushed upward into the clamping device 9. After the timing module in the control system controls the countdown, the first drive device descends, and the second drive device is used to drive the clamping device 9 to descend. The clamping device 9 drives plug-in C to descend, and the plug-in C is inserted into the gasket B after thermal expansion under the action of the continued descent of the second drive device. The transverse groove seat 3 continues to push the assembly of plug-in C and gasket B to the right end to discharge, and then returns to the origin. At this time, the first travel switch 7 fails, the heating body in the top seat 6 stops heating, and the first drive device and the second drive device return to their positions, waiting for the next use. According to the above assembly principle, the gasket B forms an interference fit after cooling and shrinking, realizing a lossless fastening connection between plug-in C and gasket B, and the hot melt effect of gasket B is used to lock and fix it with plug-in C, and complete the rapid assembly. This solves the problem of poor locking effect after the plug-in C and the gasket B are inserted, and the mechanical stress generated by the cold press assembly easily damages the brittle gasket, thereby reducing the sealing of the plug-in C and the gasket B. In the above assembly process, the top seat 6 pushes the plug-in C through the gasket B and pushes it into the clamping device 9 above for clamping, while the gasket B completes rapid thermal expansion, resulting in a compact structure, short stroke and high efficiency. Automation is achieved by using stroke control.
[0026] In addition, when the clamping device 9 carries the plug-in C and inserts it into the gasket B, the bottom end of the plug-in C will eventually fall into the transverse groove seat 3 and form pressure between the transverse groove seat 3. At this time, the clamping device 9 continues to descend, while the plug-in C stops. The top end of the plug-in C will provide a reverse thrust to the second stroke switch 8, and trigger the second stroke switch 8 to control the second drive device to drive the tooling 5 to descend. The tooling 5 drives the clamping device 9 to descend and insert the plug-in C into the gasket B to complete the tight welding assembly. At the same time, the first drive device retreats downward to the origin, and the second drive tooling 5 rises and resets after the timing module counts down. At this time, the locking force of the plug-in C inserted into the gasket B is greater than the clamping force of the clamping device 9. As the clamping device 9 rises, the assembly of the plug-in C and the gasket B is lifted upward, and cooperates with other manipulators or other material return mechanisms to achieve high-level discharging. The device drives the plug-in C to rise, and then triggers the second stroke switch 8. The power comes from the plug-in C (product) itself, and the structure is compact and simple.
[0027] A third drive device (not shown in the figure) is fixed in the horizontal frame 1, and the third drive device drives and connects to the horizontal slot seat 3. The first drive device, the second drive device and the third drive device are electric cylinders. Multiple electric cylinders and travel switches are used to form an electrical linkage relationship, realizing electrical automation and reducing mechanical coordination relationships.
[0028] like Figures 2 to 6 As shown, a first through hole 101 is opened upward in the transverse frame 1, and a second through hole 301 is opened in the transverse slot seat 3. When the transverse slot seat 3 moves to the bottom of the tooling 5, the second through hole 301 is brought to overlap with the first through hole 101. When the transverse slot seat 3 brings the washer B and the plug-in C into the bottom of the tooling 5 (assembly station), the inner ring of the washer B is connected to the first through hole 101 on the transverse frame 1 and the second through hole 301 on the transverse slot seat 3, that is, they are now in the same assembly station. The first driving device now pushes the top seat 6 to rise along the first through hole 101 and then enter the inner ring of the washer B. While continuing to rise through the second through hole 301, it pushes the plug-in C that has fallen on the washer B into the clamping device 9 of the tooling 5.
[0029] like Figure 2 、 Figure 5 as well as Figure 6 As shown, the transverse groove seat 3 includes a push seat 302 fixed on the third drive device, and also includes a carrier 303 fixed in the push seat 302. A stepped groove 304 is defined downward from the top of the carrier 303. The second through hole 301 is defined on the bottom surface of the carrier 303. The stepped groove 304 is located above the second through hole 301 and is in vertical communication with the second through hole 301. During use, the washer B is positioned on the stepped groove 304 as shown in the figure, and is then pushed into the lower part (assembly station) of the tooling 5 along with the push seat 302. After the washer B and the plug C are plugged (assembled), the terminal port on the plug C extends into the second through hole 301.
[0030] It should be further explained that a positioning plate or positioning bolt is provided on the carrier 303, and the positioning plate or positioning bolt protrudes upward from the top surface of the carrier 303 to ensure that the gasket B and the plug-in C are positioned when placed, and can be accurately assembled when sent to the position of the tooling 5 through the carrier 303. This positioning method is a prior art and will not be described in detail in the present invention.
[0031] In another embodiment, the clamping device 9 includes a pressure plate 901 fixed to the bottom of the second driving device, including a connecting frame 902 hinged on the left and right ends of the pressure plate 901, including a gas spring 903 arranged above the pressure plate 901 and drivingly connected between the left and right connecting frames 902, and a rubber roller 904 connected to the left and right connecting frames 902. The second travel switch 8 is fixed on the bottom surface of the pressure plate 901 and is located in the rising position of the top seat 6. When the top seat 6 pushes the plug-in to rise to contact with the second travel switch 8, the second travel switch 8 is triggered. The second travel switch 8 is activated, and the second driving device is activated by the second travel switch 8 to push the pressure plate 901 down. The pressure plate 901 pushes the plug-in to descend and is welded to the inner ring of the gasket. A spring seat 9011 is fixed on the bottom surface of the pressure plate 901. The spring seat 9011 faces downward and corresponds to the rising position of the plug-in. There are at least four spring seats 9011 and they are evenly distributed. The second travel switch 8 is located between the four spring seats 9011. When the plug-in rises, the top surface first squeezes the spring seat 9011 to compress the stored force, and then triggers the second travel switch 8.
[0032] In this embodiment, the top surface of the plug-in first contacts the spring seats 9011 (evenly distributed at least four locations) fixed to the bottom surface of the pressure plate 901. The spring seats 9011 contract under pressure, absorbing the upward kinetic energy of the plug-in C and storing elastic potential energy to cushion mechanical shock. Plug-in C continues to rise, passing through the gap between the spring seats 9011 before contacting the second travel switch 8 located at its center. At this point, the spring seats 9011 have been pre-compressed, ensuring precise alignment between the trigger position of the plug-in C and the second travel switch 8, eliminating the risk of false triggering due to vibration. Once the second travel switch 8 is triggered, the second drive mechanism is immediately activated to push the pressure plate 901 downward. The pressure plate 901, via the hinged connecting brackets 902 on both sides, synchronously drives the gas spring 903 and rubber roller 904 downward. The gas spring 903 provides a constant downward force, ensuring a smooth descent of the pressure plate 901. The rubber roller 904 flexibly presses against the plug-in surface, preventing rigid contact from damaging the surface. The pressure plate 901 continues to press the plug-in C downward, inserting it into the inner ring of the heat-expanded gasket B. As the gasket B cools and shrinks to form an interference fit with the insert C, the elastic pressure of the rubber roller 904 ensures that the insert C and the gasket B are tightly welded axially without displacement.
[0033] The shape of the top seat 6 is consistent with the inner ring shape of the gasket. It consists of two parts: an outer metal shell with thermal conductivity and a heating body arranged inside the metal shell to provide heating energy. The shape of the heating body is consistent with the shape of the metal shell, and the outer wall surface of the heating body is tightly attached to the inner wall of the metal shell.
