Detailed implementation manners

[0043] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0044] See Figures 1 - 3 , which shows an assembly device for a cover plate and a pole column according to a preferred embodiment of the present utility model, including:

[0045] A body 1, the body 1 is provided with a loading and unloading station and a spinning station;

[0046] A spinning device 2, the spinning device 2 is arranged on the body 1, and the spinning device 2 is used to spin the annular protrusion on the cover plate located at the spinning station, so that the pole column is limited within the annular protrusion;

[0047] A positioning seat 3, the positioning seat 3 is used to position the cover plate;

[0048] The transfer device 4 is provided on the machine body 1. The output end of the transfer device 4 can move between the loading / unloading station and the spinning station. The output end of the transfer device 4 is connected to the positioning seat 3 to drive the positioning seat 3 to move between the loading / unloading station and the spinning station, that is, to drive the cover plate to move between the loading / unloading station and the spinning station.

[0049] For the cover plate and pole column assembly equipment of the present utility model, since the transfer device 4 is provided and the positioning seat 3 is arranged at the output end of the transfer device 4, when spinning the annular convex portion of the cover plate, the transfer device 4 can be used to drive the cover plate located on the positioning seat 3, so that the cover plate can move from the loading / unloading station to the spinning station, replacing manual feeding of the cover plate from the loading / unloading station to the spinning station. Then, the annular convex portion on the cover plate located at the spinning station is spun by the spinning device 2, so that the pole column is limited within the annular convex portion to complete the assembly of the cover plate and the pole column. After that, the transfer device 4 is used to drive the cover plate located on the positioning seat 3, so that the cover plate can move from the spinning station to the loading / unloading station, replacing manual unloading of the cover plate from the spinning station to the loading / unloading station. This can not only improve the assembly efficiency of the cover plate and the pole column, but also improve the assembly safety.

[0050] See Figure 1 , in an embodiment, the transfer device 4 includes:

[0051] The transfer driving mechanism 41 is provided on the machine body 1, and the output end of the transfer driving mechanism 41 can move between the loading / unloading station and the spinning station;

[0052] The guide rail 42 is provided on the machine body 1 or on the transfer driving mechanism 41;

[0053] The slider 43 is slidably arranged on the guide rail 42. The slider 43 is connected to the output end of the transfer driving mechanism 41, and the slider 43 is connected to the positioning seat 3, that is, the slider 43 is provided with the output end of the transfer device 4. Since the transfer device 4 is provided with the guide rail 42 and the slider 43, and the positioning seat 3 is arranged on the slider 43, when the slider 43 is driven by the transfer driving mechanism 41 to move along the guide rail 42, the positioning seat 3 can be guided to move by the slidable cooperation between the slider 43 and the guide rail 42, making the movement of the positioning seat 3 smoother and more stable, improving the structural reliability, and thus improving the smoothness and stability of the cover plate loading and unloading.

[0054] See Figures 1 - 2 , in an embodiment, the guide rail 42 is arranged on the top of the transfer driving mechanism 41 to improve the space utilization rate of the top of the transfer driving mechanism 41. At the same time, it does not occupy other spaces of the transfer driving mechanism 41 and the space of the machine body 1, which is beneficial to the compact setting of the cover plate and pole column assembly equipment, making the cover plate and pole column assembly equipment more miniaturized.

[0055] See Figure 2 , in one embodiment, the transfer driving mechanism 41 includes:

[0056] A transfer driving motor 411, which is arranged on the machine body 1;

[0057] A lead screw 412, which is rotatably arranged on the machine body 1. The lead screw 412 is connected to the output end of the transfer driving motor 411, and the lead screw 412 can rotate with the output end of the transfer driving motor 411; and

[0058] A nut (not shown in the figure), which is threadedly connected to the lead screw 412 and is also connected to the slider 43. In this way, by driving the lead screw 412 to rotate through the transfer driving motor 411, the rotation of the lead screw 412 drives the nut to move along the lead screw 412, thereby driving the slider 43 to move along the guide rail 42. This can not only improve the transmission efficiency but also achieve high-precision position control, so that the positioning seat 3 can be switched between the loading and unloading station and the spinning station.

[0059] Of course, in other embodiments, the transfer driving mechanism 41 can also be any one of a cylinder, a hydraulic cylinder, etc.

[0060] See Figures 1 - 2 , in one embodiment, the spinning device 2 includes:

[0061] A first lifting mechanism 21, which is arranged on the machine body 1;

[0062] A spinning mechanism 22, which is arranged on the output end of the first lifting mechanism 21. The spinning mechanism 22 can lift with the output end of the first lifting mechanism 21 to approach or move away from the spinning station. The spinning mechanism 22 is used to spin the annular convex part on the cover plate located at the spinning station to limit the pole column within the annular convex part;

[0063] A second lifting mechanism 23, which is arranged on the machine body 1;

[0064] The pressure rod 24 is connected to the output end of the second lifting mechanism 23. The pressure rod 24 can be lifted and lowered with the output end of the second lifting mechanism 23. The pressure rod 24 is used to press the pole column to limit the pole column in the pole column mounting hole of the cover plate. In this way, when spinning the annular convex part, the second lifting mechanism 23 drives the pressure rod 24 to descend to press the pole column, so as to limit the pole column in the pole column mounting hole of the cover plate and prevent the pole column from moving. At the same time, the first lifting mechanism 21 drives the spinning mechanism 22 to descend to abut against the annular convex part, and then the spinning mechanism 22 spins the annular convex part, so as to limit the pole column in the annular convex part, thereby assembling the cover plate and the pole column together. After that, the second lifting mechanism 23 drives the pressure rod 24 to rise away from the pole column and the first lifting mechanism 21 drives the spinning mechanism 22 away from the annular convex part, so that the cover plate can move from the spinning station to the loading and unloading station under the drive of the transfer device 4.

[0065] See Figures 1 - 2 , in one embodiment, the spinning mechanism 22 includes:

[0066] The rotary driver 221 is arranged on the output end of the first lifting mechanism 21. The rotary driver 221 can be lifted and lowered with the output end of the first lifting mechanism 21;

[0067] The spinning wheel 222 is arranged on the output end of the rotary driver 221. The spinning wheel 222 can rotate with the output end of the rotary driver 221. The spinning wheel 222 is used to spin the annular convex part on the cover plate located at the spinning station, so that the pole column is limited in the annular convex part. That is, by abutting the spinning wheel 222 against the annular convex part and simultaneously driving the spinning wheel 222 to rotate around the axial center line of the pole column by the rotary driver 221, the spinning of the annular convex part can be realized. The structure is simple and practical, the spinning accuracy is high, and the cover plate and the pole column can be reliably assembled together.

[0068] In one embodiment, the number of the spinning wheels 222 is two, and the two spinning wheels 222 are respectively placed on the opposite sides of the pressure rod 24. In this way, the two spinning wheels 222 can be used to spin the annular convex part simultaneously, which can not only improve the spinning efficiency but also improve the spinning accuracy.

[0069] For the convenience of installing the spinning wheel 222, in one embodiment, the spinning drive mechanism further includes:

[0070] The rotary seat 223 is connected to the output end of the rotary driver 221. The spinning wheel 222 is arranged on the bottom of the rotary seat 223.

[0071] See Figure 3, in one embodiment, the spinning wheel 222 is provided with a limiting surface 2221 and a spinning surface 2222. The limiting surface 2221 and the spinning surface 2222 are connected by an arc surface 2223. The limiting surface 2221 is used to be limited outside the annular convex part, and the spinning surface 2222 is used to extrude the top surface of the annular convex part. In this way, the spinning of the annular convex part can be realized through the cooperation of the limiting surface 2221 and the spinning surface 2222, so that the annular convex part and the pole column are reliably riveted together, and the structural reliability is higher. At the same time, since the limiting surface 2221 and the spinning surface 2222 are connected by the arc surface 2223, another arc surface 2223 matching the arc surface 2223 can also be formed on the annular convex part, which is beneficial to reducing the stress of the annular convex part after riveting and making the annular convex part and the pole column be reliably riveted together.

[0072] See Figure 2 , in one embodiment, the spinning device 2 further includes:

[0073] A connecting seat 25, the connecting seat 25 is connected to the output end of the first lifting mechanism 21, and the spinning mechanism 22 is arranged on the connecting seat 25, so as to facilitate the installation of the spinning mechanism 22 on the output end of the first lifting mechanism 21;

[0074] A guiding seat 26, the guiding seat 26 is arranged on the connecting seat 25, the guiding seat 26 has a guiding hole, the guiding hole is for the pressing rod 24 to pass through, and the guiding hole and the pressing rod 24 are slidably matched to guide the lifting of the pressing rod 24, so that the movement of the pressing rod 24 is smoother and more stable, so as to realize reliably pressing the pole column into the annular convex part.

[0075] In one embodiment, both the first lifting mechanism 21 and the second lifting mechanism 23 can be air cylinders or hydraulic cylinders.

[0076] In one embodiment, the spinning driver can be a motor, a rotary air cylinder or a hydraulic rotary cylinder.
