[0019] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0020] like Figure 1-Figure 7The illustrated shelf welding positioner comprises a base frame 1, a rotating plate 2 is installed on the upper surface of the base frame 1 through a servo rotating mechanism, a vertical plate 3 is fixedly installed on one side of the upper surface of the rotating plate 2, a lifting plate 5 is inserted at the upper end of one side of the vertical plate 3 through a lifting mechanism, and two connecting frames 8 are fixedly installed on one side of the vertical plate 3. Two connecting frames 8 are connected to two moving rods 11 through a telescopic mechanism on the sides away from each other, and the two moving rods 11 are fixedly connected to a connecting rail 12 at the ends close to each other, and the two moving rods 11 are fixedly connected to the connecting rails 12 at the ends away from each other, and a concave frame 13 is inserted on the side of the connecting rail 12 away from the connecting frame 8 through a clamping mechanism, and the two ends of the concave frame 13 are fixedly connected to the inclined guide plates 16. The inclined guide plates 16 play a guiding role, and when the connecting rod body 33 is arranged, it can enter the inner side of the concave frame 13 more smoothly.

[0021] like Figure 5 , Figure 6 As shown, the servo rotating mechanism includes a slide 22 slidably mounted on the upper surface of the base frame 1, a rotating seat 23 is rotatably embedded on the upper surface of the slide 22, the upper end of the rotating seat 23 is fixedly connected to the lower surface of the rotating plate 2, and a motor 25 is fixedly mounted on the lower surface of the slide 22 through a bottom bracket 24, and the output shaft of the motor 25 is fixedly connected to the lower surface of the rotating seat 23. The bottom bracket 24 is used to ensure that the motor 25 is stably mounted on the lower surface of the slide 22, so that the motor 25 can move laterally with the slide 22.

[0022] The front and rear edges of the upper surface of the base frame 1 are fixedly connected with guide rails 26 respectively, the lower surface of the slide 22 is slidably matched with the guide rails 26, a screw rod 27 is rotatably installed on the inner side of the base frame 1, a power assembly 28 is fixedly installed at a corner of one side of the base frame 1, the output shaft of the power assembly 28 is fixedly connected to one end of the screw rod 27, and a threaded sleeve 29 is fixedly connected to the lower surface of the slide 22, and the screw rod 27 is threaded through the inner side of the threaded sleeve 29. The power assembly 28 is composed of a servo motor and a gear box, which is used to control the rotation of the screw rod 27, so that the threaded sleeve 29 moves laterally along the surface of the screw rod 27, so that the slide 22 moves laterally, preventing the entire shelf frame from deviating too far from the central axis of the rotation of the rotating plate 2, causing the problem of sweeping too large a range when the shelf frame rotates.

[0023] like Figure 2As shown, the lifting mechanism includes a mounting base 7 fixedly mounted on the surface of one side of the vertical plate 3, a lifting cylinder 6 is fixedly mounted on the upper end surface of the mounting base 7, a sliding opening 4 is penetrated through the upper end of the surface of one side of the vertical plate 3, a lifting plate 5 and the sliding opening 4 are slidably matched along the vertical direction, and the lower surface of the lifting plate 5 is fixedly connected to the telescopic end of the lifting cylinder 6. By controlling the extension and contraction of the lifting cylinder 6, the lifting plate 5 slides up and down along the inner side of the sliding opening 4, and the distance between the upper frame 32 and the bottom frame 31 can be adjusted to ensure that the connecting rod body 33 can be well connected between the upper frame 32 and the bottom frame 31 after being inserted.

[0024] like Figure 3 As shown, the telescopic mechanism includes a telescopic cylinder 9 fixedly passing through the outer surface of the connecting frame 8, the telescopic end of the telescopic cylinder 9 is fixedly connected to the outer surface of the moving rod 11, and the side of the moving rod 11 close to the connecting frame 8 is fixedly connected to the guide rod 10, and the guide rod 10 slides through the outer surface of the connecting frame 8. The guide rod 10 is used to ensure the stability of the moving rod 11 when it moves. When setting, the telescopic end of the telescopic cylinder 9 and one end of the guide rod 10 may not be connected to the same surface of the moving rod 11.

[0025] like Figure 4 As shown, a sliding groove 14 is provided on the surface of the connecting rail 12 away from the connecting frame 8, a slider 15 extends from the outer surface of the concave frame 13, and the slider 15 slides and snaps into the inner side of the sliding groove 14. A pressing plate 17 is connected to the upper surface of the connecting rail 12 through an elastic mechanism, and the pressing plate 17 presses the upper surface of the slider 15. A handle 21 is fixedly connected to the outer surface of the pressing plate 17. The handle 21 is convenient for the user to pull the pressing plate 17.

[0026] The elastic mechanism includes a fixed column 18 fixedly connected to the upper surface of the connecting rail 12, the upper end of the fixed column 18 slides through the lower surface of the pressing plate 17, and the upper end of the fixed column 18 is fixedly connected to an anti-slip head 19, and the outer surface of the fixed column 18 is sleeved with a compression spring 20, and the compression spring 20 is located between the anti-slip head 19 and the pressing plate 17. The anti-slip head 19 prevents the compression spring 20 from detaching from the fixed column 18.

[0027] like Figure 6 As shown, the bottom corner of the bottom surface of the base frame 1 is threadedly connected with a foot 30. By rotating the foot 30, the foot 30 moves up and down relative to the base frame 1 to adapt to the uneven ground for arrangement.

[0028] The user places the bottom frame 31 on the surface of the rotating plate 2, with the side thereof abutting against the side surface of the vertical plate 3, and then places the upper frame 32 on the upper surface of the lifting plate 5, with the side thereof also abutting against the side surface of the vertical plate 3. Afterwards, the connecting rod 33 is inserted into each concave frame 13, so that the bottom frame 31, the upper frame 32 and the connecting rod 33 together form a shelf frame, as shown in FIG. Figure 7As shown, the user then uses a welding gun to weld the connection between the connecting rod body 33 and the bottom frame body 31, and the connection between the connecting rod body 33 and the upper frame body 32, thereby assisting in positioning the welded parts, improving welding accuracy, and reducing welding difficulty.

[0029] After completing the arrangement of the welding parts, the user stands in front of the base frame 1 and welds the connection between the connecting rod body 33 and the base frame body 31, and the connection between the connecting rod body 33 and the upper frame body 32 respectively. After welding all the points close to the front, the welding parts are reversed by controlling the rotation of the motor 25, so that the points that were not welded at the rear reach the front, so as to facilitate the continuation of welding and make the welding process more convenient.

[0030] After the welding is completed, the telescopic cylinder 9 is controlled to retract so that the concave frame 13 is separated from the connecting rod body 33. After that, the unloading step can be completed by horizontally moving the entire welded shelf frame body, which is convenient to operate.

[0031] The user lifts the pressure plate 17 by the handle 21 to squeeze the compression spring 20. After the pressure plate 17 no longer presses the slider 15, the slider 15 can be moved laterally along the inner side of the slide groove 14 to adjust the position of the concave frame 13, that is, to adjust the arrangement position of the connecting rod body 33 between the bottom frame body 31 and the upper frame body 32, which is convenient to adjust and flexible to use.
