Description

Technical Field

[0001] The utility model belongs to the technical field of electrical equipment-medium voltage switches, and in particular relates to a device for flipping, twisting and adjusting the position of an assembly table during the assembly and detection of a pole-mounted switch. Background Art

[0002] During the assembly process of the ZW32 model primary and secondary fusion column-mounted circuit breaker production line, the product needs to be hoisted from the cart with the vacuum interrupter to the assembly table of the assembly line. During the running-in room, mechanical property testing, pressure resistance testing, and complete set testing, the product needs to be flipped, twisted, and the position of the assembly table adjusted to achieve the working conditions of different positions. Due to the heavy weight of the primary and secondary fusion products, the traditional assembly table requires two people to move and flip at the same time during the work process of different positions. The frequent movement of the tooling board makes the device driven by electricity to flip prone to safety hazards. Different workstations need to be set according to different heights. In addition, the on-off gas of the cylinder becomes inconvenient for production, which easily leads to waste of working time.

[0003] One solution of the prior art is to use a tooling vehicle. CN209938664U discloses a lifting and flipping tooling vehicle device, which adopts a chassis vehicle with a frame, a flipping device, a lifting cylinder and a lifting frame driven by the lifting cylinder. The lifting frame is provided with a reduction box, and the flipping device includes a flipping frame fixedly connected to the output shaft of the reduction box, a fixed plate and two steering clamping mechanisms. The flipping frame includes a turntable and two clamping arms. The steering clamping mechanism includes a fixed rod fixedly connected to the fixed plate, a rotating rod hinged to the fixed rod, a screw threadedly connected to the rotating rod, a rotating handle arranged at one end of the screw and a clamp arranged at the other end of the screw. A box body is fixed on the clamp, a jack is arranged on the box body, a card block is arranged on the box body, and the other end of the screw is inserted into the jack of the box body and fixedly connected to the card block. This solution enables the tooling vehicle to move freely, and the tooling vehicle can realize functions such as flipping and lifting, but the structure is relatively complex, and manual flipping and movement are required. It is not suitable for large-scale assembly line operation, and it is not convenient to debug mechanical characteristics and complete set detection.

[0004] The second solution of the prior art is used for production lines, using a turbine screw as the main shaft and a vertical bearing seat as the auxiliary movement, and manually flipping the product. However, the product needs to be turned back and forth and hoisted for assembly and testing at different workstations, which wastes working hours and poses safety issues. Utility Model Content

[0050] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0051] Example 1

[0052] The utility model provides a column switch flip device, which is combined with Figure 1 , 2 3. Introduce the structure and connection relationship of the device:

[0053] A column switch flip device comprises a large torque 180° rotating cylinder 1; a cylinder mounting plate 2; a column left bracket 3; a two-position three-way handle type air valve 4; a tooling plate bottom plate 5; a reinforced angle steel 6; a heavy-duty bearing seat A 7; an angle limit plate 8; a left bent plate 9; a right bent plate 10; a heavy-duty bearing seat B11; a shaft sleeve 12; a column right bracket 13; a key A14; a limit pin 15; a column switch 16; and a key B17.

[0054] The left curved plate and the right curved plate adopt a plate bending design, and the curved plate has a certain depth, so that the center of gravity moves toward the rotation center during the flipping process, which can reduce the flipping strength to a certain extent;

[0055] Among them, the column left bracket 3, the column right bracket 13, and the reinforcing angle steel 6 are fixed on the tooling plate bottom plate 5 by welding;

[0056] The heavy-duty bearing seat A 7 is mounted on the top surface of the left bracket 3 of the column by welding;

[0057] The cylinder mounting plate 2 is mounted on the left end surface of the heavy-duty bearing seat A 7 by welding;

[0058] The high torque 180° rotating cylinder 1 is mounted on the cylinder mounting plate 2;

[0059] The angle limit plate 8 is fixed to the right end surface of the heavy-duty bearing seat A 7;

[0060] The left curved plate 9 is connected to the angle limit plate 8 through an elastic cylindrical pin and is limited by a gasket and a bolt; the left curved plate 9 passes through the heavy-duty bearing seat A 7 and is connected to the large torque 180° rotating cylinder 1 through a key B17;

[0061] The limiting pin 15 is fixed to the right end surface of the left support 3 of the column to limit the angle limiting plate 8;

[0062] When the flip device is in two working states (insulating cylinder assembly station or isolating knife assembly station), the air valve drives the cylinder to provide a large torque to keep the working posture of the flip device unchanged. However, since the center of gravity of the flip device changes, the limit pin 15 can be used to pin the angle limit plate 8 to fix the working posture of the column switch flip device; at the same time, the spring spiral hose can be unplugged at this time, so that the entire flip device can move freely on the assembly line body;

[0063] The shaft sleeve 12 passes through two heavy-duty bearing seats B11;

[0064] The right curved plate 10 passes through the shaft sleeve 12 and is connected to two heavy-duty bearing seats B11 through a key A14, and is limited by gaskets and bolts;

[0065] The column switch 16 is installed between the left curved plate 9 and the right curved plate 10;

[0066] A two-position three-way handle type air valve 4 is installed on the left support 3 of the column, and a pneumatic throttle valve is installed on the two-position three-way handle type air valve 4 to adjust the exhaust volume;

[0067] The two-position three-way handle-type air valve 4 is connected to the torque 180° rotating cylinder 1 through a 10mm air pipe;

[0068] The two-position three-way handle-type gas valve 4 is connected to an external gas source through an 8mm spring spiral hose.

[0069] The pole switch flip device has two working postures when it is in working state. One is the working posture that meets the requirements of the insulating cylinder assembly station, and the other is the working posture that meets the requirements of the isolation knife assembly station. Figure 1 , 2 4. Introduce the assembly position of the insulation tube assembly station.

[0070] The spring spiral hose is connected to the external air source, and the two-position three-way handle air valve 4 is turned to adjust the large torque 180° rotating cylinder 1 to the position as shown in the figure. Figure 1The working posture shown is the installation position of the insulating cylinder and the mechanism components. In this working posture, the height of the left curved plate 9 and the right curved plate 10 to the ground is 1300mm, and the installation position of the insulating cylinder is 1000mm above the ground, which is convenient for production staff to install the insulating cylinder. In this position, the working posture of the column switch flip device can be fixed by using the limit pin 15 to pin the angle limit plate 8, and then the spring spiral hose can be unplugged so that the entire flip device can move freely on the assembly line body. During the cylinder flipping process, the large torque 180° rotating cylinder 1 and the heavy-duty bearing seat A 7 and two heavy-duty bearing seats B11 can ensure the stability of the product flipping during the cylinder flipping process.

[0071] Combine the following Figure 3 , 5 Introduce the assembly position of the isolation knife assembly station.

[0072] The spring spiral hose is connected to the external air source, and the two-position three-way handle air valve 4 is turned to adjust the large torque 180° rotating cylinder 1 to the position as shown in the figure. Figure 3 The working posture shown is the installation position of the isolation knife and mechanism components. In this working posture, the height of the left curved plate 9 and the right curved plate 10 to the ground changes to 1000mm, and the installation position of the isolation knife is 1300mm above the ground. Employees can easily install the isolation knife. In this position, the working posture of the column switch flip device can be fixed by using the limit pin 15 to pin the angle limit plate 8, and then the spring spiral hose can be unplugged so that the entire flip device can move freely on the assembly line body. During the cylinder flipping process, the large torque 180° rotating cylinder 1 and the heavy-duty bearing seat A 7 and two heavy-duty bearing seats B11 can ensure the stability of the product flipping during the cylinder flipping process.
