DETAILED DESCRIPTION

The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

A specific embodiment of the utility model, as shown in Figures 1 to 4, discloses a double-sided turntable for box-type steel structure modules (hereinafter referred to as the double-sided turntable). The double-sided turntable is used for pre-loading the connection box 100 and feeding the welding robot, and clamping the connection box 100 before welding. The operator uses a crane to place the riveted connection box 100 on the upper part side of the double-sided turntable, clamps and positions it to complete the preparation before welding, and the clamped connection box 100 turns 180° to one side of the welding robot. While the welding robot is welding, the other side is loaded (i.e., the connection box 100 to be welded).

As shown in FIG1 , the double-sided turntable includes a displacement base 11 , a displacement drive unit 12 and an upper workbench 13 . The upper workbench 13 is disposed above the displacement base 11 . The displacement drive unit 12 is disposed on the displacement base 11 for driving the upper workbench 13 to rotate.

In this embodiment, an upper workbench 13 is provided above the displacement base 11. Driven by the displacement drive unit 12, the upper workbench 13 can rotate 180°. The connection box 100 is arranged on the upper workbench 13 for welding. The upper workbench 13 is divided into two working areas, namely a first working area 131 and a second working area 132. While one working area is used for welding, the other working area is used for loading (the connection box 100 that has not been welded). For example, when the first working area 131 is used for welding, the second working area 132 is used for loading. The rotation of the upper workbench 13 allows the two working areas to be alternately replaced, and the connection boxes 100 to be welded are kept in the two working areas, so as to avoid the waiting of the welding robot and improve the welding operation efficiency of the connection box 100.

Specifically, as shown in FIG2 , the displacement drive unit 12 includes a first drive motor 121, a first bevel gear 122 and a second bevel gear 123, the first bevel gear 122 and the second bevel gear 123 are arranged in the displacement base 11, and accordingly, a cavity is provided in the displacement base 11 for accommodating the first bevel gear 122 and the second bevel gear 123 and corresponding components (such as a connecting shaft, a bearing, etc.). The first drive motor 121 is arranged on the outer side of the displacement base 11, the output shaft of the first drive motor 121 is connected to the first transmission shaft 124, the first bevel gear 122 is arranged on the first transmission shaft 124, the first bevel gear 122 is meshed with the second bevel gear 123 arranged on the second transmission shaft 125, and the upper workbench 13 is connected to the second transmission shaft 125. The rotation connection between the displacement drive unit 12 and the displacement base 11 is provided with a bearing, such as the connection part between the first transmission shaft 124 and the displacement base 11, and the connection part between the second transmission shaft 125 and the displacement base 11 are both provided with a bearing.

The first drive motor 121 drives the first transmission shaft 124 to rotate, thereby driving the first bevel gear 122 to rotate. Since the second bevel gear 123 is provided on the second transmission shaft 125 and meshes with the first bevel gear 122, the second transmission shaft 125 rotates and drives the upper workbench 13 to rotate.

In order to place the connection box 100, as shown in Fig. 1, the double-sided turntable further includes a positioning assembly 14, which is used to position the connection box 100. The positioning assembly 14 is installed on the upper workbench 13, and each work area is provided with a positioning assembly 14.

Specifically, two positioning components 14 are symmetrically arranged at both ends of the upper workbench 13. As shown in FIG3 , the positioning component 14 includes a positioning plate 141 and a positioning block 142. The positioning plate 141 is arranged on the upper workbench 13. Exemplarily, the positioning plate 141 and the upper workbench 13 are fixedly connected by screws. The positioning plate 141 is provided with a plurality of positioning grooves 143, and the plurality of positioning grooves 143 are distributed in a rectangular shape, that is, the four sides of the rectangle are provided with positioning grooves 143. The positioning block 142 is arranged in the positioning groove 143, and can adjust its position along the positioning groove 143 to press against the connection box 100.

Correspondingly, as shown in Figure 3, first connecting holes 1421 are evenly distributed along the length direction of the positioning block 142, and second connecting holes 1431 are evenly distributed along the length direction of the positioning slot 143. Screws or bolt fasteners are used to pass through the first connecting holes 1421 and the second connecting holes 1431 to fix the positioning block 142 to the positioning slot 143.

It should be noted that the connection box 100 is usually a rectangular block, so the multiple positioning slots 143 are distributed in a rectangular shape. The multiple positioning slots 143 can also form other shapes, such as a circle. The shape formed by the multiple positioning slots 143 depends on the shape of the connection box 100.

In this embodiment, positioning grooves 143 are evenly distributed around the connection box 100, and a positioning block 142 is provided in the positioning groove 143. The position of the positioning block 142 in the positioning groove 143 can be adjusted, and the area enclosed by the adjusted positioning block 142 is used to place the connection box 100, that is, the outer contour of the connection box 100 is adapted by adjusting the installation position of the positioning block 142 in the positioning groove 143, so that the positioning of the connection box 100 is achieved.

Considering that the upper workbench 13 rotates intermittently, the connection box 100 is not stable only by the positioning block 142. In order to press the connection box 100 placed on the upper workbench 13, as shown in Figure 1, the double-sided turntable also includes a pressing assembly 15. Two sets of pressing assemblies 15 are provided in each working area.

As shown in Fig. 3, the pressing assembly 15 includes a pressing arm 151 and a pressing arm cylinder 152. The pressing arm cylinder 152 is connected to the upper workbench 13, and the pressing arm cylinder 152 drives the pressing arm 151 to swing. When the push rod of the pressing arm cylinder 152 is extended, the pressing arm 151 swings downward to press the connection box 100, and when the push rod of the pressing arm cylinder 152 is retracted, the pressing arm 151 swings upward to break away from the contact with the connection box 100.

Further, as shown in FIG4 , the clamping assembly 15 further includes a rack 153, a gear 154 and a rotating shaft 155. The rack 153 is arranged at the front end of the push rod of the pressure arm cylinder 152. The rotating shaft 155 is fixedly connected to one end of the pressure arm 151. The other end of the pressure arm 151 is a clamping portion 1511. The gear 154 is arranged on the rotating shaft 155 and meshes with the rack 153. The push rod of the pressure arm cylinder 152 extends, driving the rack 153 to move upward. The movement of the rack 153 drives the gear 154 to rotate. The rotating shaft 155 rotates synchronously with the gear 154, and then drives the pressure arm 151 to rotate, so that the clamping portion 1511 clamps the connection box 100. It should be noted that the clamping portion 1511 is a flat structure, which is conducive to large-area contact with the connection box 100.

In this embodiment, the connection box 100 is positioned by a positioning assembly 14, and the connection box 100 disposed on the upper workbench 13 is pressed by a clamping assembly 15. The positioning assembly 14 and the clamping assembly 15 cooperate to firmly set the connection box 100 on the upper workbench 13, thereby preventing the connection box 100 from tipping over during the rotation of the upper workbench 13, thereby improving the work quality.

Taking into account that the connection box 100 has different sizes, the clamping assembly 15 needs to adjust its height to accommodate connection boxes 100 of different sizes. As shown in FIG1 , the double-sided turntable also includes a height adjustment assembly 16, which is mounted on the upper workbench 13, and the clamping assembly 15 is connected to the height adjustment assembly 16.

As shown in Figure 3, the height adjustment assembly 16 includes a height adjustment column 161 and a connecting seat 162. One end of the height adjustment column 161 is connected to the upper workbench 13, and the other end of the height adjustment column 161 is connected to the connecting seat 162. The position of the connecting seat 162 on the height adjustment column 161 can be adjusted to adapt to connection boxes 100 of different sizes.

Specifically, as shown in Figure 3, the upper part of the height adjustment column 161 is evenly distributed with third connecting holes 1611, and the connecting seat 162 is provided with a fourth connecting hole 1621. Screws or bolt fasteners are used to pass through the third connecting holes 1611 and the fourth connecting holes 1621 to connect the connecting seat 162 and the height adjustment column 161 together. The fourth connecting hole 1621 cooperates with the third connecting holes 1611 of different heights to adjust the setting height of the connecting seat 162, thereby realizing the height adjustment of the clamping assembly 15 connected to the connecting seat 162.

The arm-pressing cylinder 152 is connected to the bottom of the connecting seat 162. The connecting seat 162 has a cavity inside. The telescopic rod, rack 153, gear 154 and part of the rotating shaft 155 of the arm-pressing cylinder 152 are located in the cavity of the connecting seat 162. Specifically, as shown in FIG3 , both ends of the rotating shaft 155 are rotatably connected to the connecting seat 162. The connecting end of the arm-pressing cylinder 152 and the rotating shaft 155 is a Y-shaped structure 1512. The top of the connecting seat 162 is located in the groove 1513 of the Y-shaped structure. The two ends of the rotating shaft 155 are fixedly connected to the two side walls of the groove 1513, respectively.

In this embodiment, the telescopic rod, rack 153, gear 154 and part of the rotating shaft 155 of the pressure arm cylinder 152 are arranged in the cavity of the connecting seat 162, which can protect the above components from being contaminated by dust, particles, etc. in the external environment to ensure transmission accuracy.

Taking into account that arc will be generated during welding of the connection box 100 located on one side of the upper workbench 13, and that materials are manually loaded on the other side of the upper workbench 13, in order to prevent the arc generated during welding from damaging the eyesight of the workers, as shown in FIG1 , the double-sided turntable also includes a shading plate 17, the lower end of which is connected to the upper workbench 13, the shading plate 17 is vertically arranged and located in the middle of the upper workbench 13, dividing the upper workbench 13 into a first working area 131 and a second working area 132.

The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
