DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] When implementing: Figures 1-4 As shown, a positioning device for welding display stand partitions with a positioning and locking function includes a base 100 and a support plate installed on the top thereof; a positioning mechanism 200, and the positioning mechanism 200 is arranged on one side of the support plate; wherein, the positioning mechanism 200 includes a processing box 210 and a group of arc-shaped folding plates 220, and the inner wall of the arc-shaped folding plate 220 is provided with an arc-shaped slot 226, and the arc-shaped folding plate 220 is slidably connected to the processing box 210, and the outer side of the arc-shaped folding plate 220 is provided with an air guide tube 230 extending to the interior of the processing box 210.

[0025] like Figure 1 、 Figure 2 and Figure 4 As shown, the positioning mechanism 200 also includes two arc-shaped folding strips 240, one arc-shaped folding strip 240 is slidably connected to the top of the base 100, and the remaining arc-shaped folding strip 240 is installed to the top of the base 100 by bolts, and a feeding slot is opened inside the processing box 210.

[0026] Before the welding process, the stand column seat can be placed on the base 100, and the outer side is placed in an arc-shaped folding strip 240, the pre-fixing of the column seat is completed, and at this time the column will be in the feeding channel in the processing box 210. Then the user can put the partition plate along the outside of the column, and the partition plate is placed on the processing box 210. At this time, the corresponding arc-shaped folding plate 220 is actuated, and then when the bottom of the partition plate and the bottom of the arc-shaped folding plate 220 are at the same horizontal plane, the arc-shaped folding plate 220 is used to pre-fix the partition plate. When formal positioning is performed subsequently, gas is introduced along the gas guide pipe 230, the arc-shaped folding plate 220 is pressed, the arc-shaped clamping groove 226 on the inner wall of the arc-shaped folding plate 220 clamps and fixes the upper part of the outer side of the partition plate, and the partition plate is positioned in two directions. At this time, the arc-shaped folding plate 220 and the arc-shaped folding strip 240 complete the horizontal and vertical positioning of the column seat and the partition plate, effectively reducing the accidental longitudinal shaking of the workpiece during the welding process, and ensuring the positioning effect and the subsequent welding effect.

[0027] As shown in Figure 1 , Figure 2 and Figure 3 , the top of the base 100 is provided with a horizontal pipe 110, the inside of the horizontal pipe 110 is provided with an electric push rod 111, one end of the electric push rod 111 is provided with a piston disc 112 which is slidingly connected to the inside of the horizontal pipe 110, and a butt joint pipe 113 is arranged between the horizontal pipe 110 and the processing box 210 for communication; the outer side of the arc-shaped folding plate 220 is provided with a support box 221 which communicates with the gas guide pipe 230, and the inside of the support box 221 is slidingly connected with a piston plate 222, and the piston plate 222 and the arc-shaped folding plate 220 are provided with a transmission rod 223 which passes through the support box 221.

[0028] The electric push rod 111 is operated to drive the piston disc 112 to guide the gas in the horizontal pipe 110 to the support box 221 through the butt joint pipe 113, so as to drive the piston plate 222 and the transmission rod 223, and the arc-shaped folding plate 220 is pressed to move and clamp and fix the outer side of the partition plate.

[0029] As shown in Figure 1 and Figure 3 , one end of the electric push rod 111 is fixedly provided with a sliding bar 114 which extends to the outside of the horizontal pipe 110, one end of the sliding bar 114 is fixedly connected with the outer side of the arc-shaped folding strip 240 close to the horizontal pipe 110, and the piston disc 112 is fixedly installed to the outside of the sliding bar 114.

[0030] During the operation of the electric push rod 111, the sliding bar 114 drives the corresponding arc-shaped folding strip 240, so that the two arc-shaped folding strips 240 clamp and position the column seat.

[0031] As shown in Figure 2 , a group of rubber balls 224 are embedded in the inner top wall of the arc-shaped folding plate 220.

[0032] The rubber ball 224 is used to increase the pre-fixing effect of the partition plate. The deformable property of the rubber ball 224 is used to press and limit the top of the partition plate, so as to reduce the accidental movement of the partition plate before locking and fixing.

[0033] As shown in Figure 2 and Figure 3 , the inside of the support box 221 is provided with a spring 225, one end of the spring 225 is fixedly installed to the outside of the piston plate 222; the outside of the butt joint pipe 113 is installed with a breather pipe 115, the outside of the breather pipe 115 is installed with an electromagnetic valve 116, the material of the butt joint pipe 113 is plastic hose, which is convenient for pipeline air guiding when the hydraulic rod drives the processing box 210 to move up and down.

[0034] After the welding work is completed, the electromagnetic valve 116 on the breather pipe 115 can be opened, so that the gas in the butt joint pipe 113 can flow with the outside world, then the spring 225 drives the piston plate 222 to reset, so that the arc-shaped folding plate 220 can move, and at the same time, the electric push rod 111 is driven to reset, so that the user can take down the completed welding work partition plate and column seat along the feeding channel.

[0035] As shown in Figure 1 , the inside of the support plate is installed with a hydraulic rod, one end of the hydraulic rod is installed with a sliding block fixedly connected with the outside of the processing box 210.

[0036] The user can start the hydraulic rod according to the welding position required by the partition plate, so that the hydraulic rod drives the sliding block to change the height position of the processing box 210, so as to meet the welding demand.

[0037] Working principle: before welding, the stand column seat can be placed on the base 100, and the outer side is placed in an arc-shaped folding strip 240, and the pre-fixing of the column seat is completed. At this time, the column will be in the feeding channel in the processing box 210. Then the user can put the partition plate along the outside of the column, and the partition plate is placed on the processing box 210. At this time, the corresponding arc-shaped folding plate 220 is pushed, and then when the bottom of the partition plate and the bottom of the arc-shaped folding plate 220 are at the same level, the arc-shaped folding plate 220 is driven by the spring 225 to pre-fix the partition plate. Then use the electric push rod 111 to operate, make the sliding bar 114 drive the corresponding arc-shaped folding strip 240, make two arc-shaped folding strips 240 clamp and position the column seat. Before the two arc-shaped folding strips 240 pre-fix the column seat, close the electromagnetic valve 116 at this time, so that the piston disc 112 drives a small amount of gas in the horizontal pipe 110 to be discharged along the butt joint pipe 113, so that the gas is introduced into the support box 221 along the gas guide pipe 230, so as to drive the piston plate 222 and the transmission rod 223 to press the arc-shaped folding plate 220, so that the arc-shaped clamping groove 226 on the inner wall of the arc-shaped folding plate 220 clamps and fixes the upper part of the outer side of the partition plate, and the two-way positioning is completed. At this time, the arc-shaped folding plate 220 and the arc-shaped folding strip 240 complete the transverse and longitudinal positioning of the column seat and the partition plate, effectively reducing the accidental longitudinal shaking of the workpiece in the welding process, ensuring the positioning effect and the subsequent welding effect.

[0038] During the whole process, the column seat and the partition plate can be quickly pre-fixed, reducing the positioning error in the later positioning process, and cooperating with the later positioning and locking, effectively ensuring the positioning effect.

[0039] It should be noted that the driving of the arc-shaped folding plate 220 is a small amount of gas, and the specific introduction time and amount are related to the size of the column seat and the partition plate.

[0040] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity. The skilled person should consider the specification as a whole, and the technical solutions in each embodiment can be combined to form other embodiments that can be understood by those skilled in the art.
