DETAILED DESCRIPTION

[0022] The present invention is now further described in conjunction with the accompanying drawings. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0023] like Figure 2 to Figure 4 As shown, an automatic positioning device for a U-shaped member includes a bracket 20, the top of the bracket 20 has a mounting top surface 201, and the left and right ends of the mounting top surface 201 are respectively fixed with a left positioning seat 1 and a right positioning seat 2, the left positioning seat 1 and the right positioning seat 2 have the same structure and are both right-angle structures, and a left sliding member and a right sliding member are respectively arranged on the mounting top surface 201 close to the left positioning seat 1 and the right positioning seat 2, a left return spring 13 is connected between the left sliding member and the end surface of the left positioning seat 1, and a first sliding member is arranged on the left sliding member, A first return spring 11 is connected between the first sliding member and the side surface of the left positioning seat 1, a right return spring 14 is connected between the right sliding member and the end surface of the right positioning seat 2, a second sliding member is provided on the right sliding member, a second return spring 12 is connected between the second sliding member and the side surface of the right positioning seat 2, a driving wheel 17 is provided on the inner side of the second sliding member and the first sliding member, and a third sliding member driven by a driving cylinder 19 is provided between the left sliding member and the right sliding member, and the third sliding member has a push-out portion matched with the driving wheel 17. In this embodiment, the left sliding member is the left positioning plate 9, the first sliding member is the first positioning plate 7, the right sliding member is the right positioning plate 10, the second sliding member is the second positioning plate 8, and the third sliding member is the positioning drive plate 16.

[0024] A left guide rail 5 is fixed to the left positioning seat 1 and a left positioning plate 9 is arranged on the left guide rail 5 to slide left and right along the left positioning plate 9. The left positioning plate 9 is L-shaped, and a left return spring 13 is connected between the vertical section and the end surface of the left positioning seat 1. A first guide rail 3 is arranged on the left positioning plate 9 and a first positioning plate 7 is arranged on the first guide rail 3 to slide forward and backward along the left positioning plate 1. A first baffle 71 is arranged vertically at the rear end of the first positioning plate 7, and the width of the first baffle 71 is greater than the width of the left positioning plate 9.

[0025] A right guide rail 6 is fixed to the right positioning seat 2 and a right positioning plate 10 is arranged on the right guide rail 6 to slide left and right along the right positioning plate 10. The right positioning plate 10 is L-shaped, and a right return spring 14 is connected between the vertical section of the right positioning plate 10 and the end surface of the right positioning seat 2. A second guide rail 4 is arranged on the right positioning plate 10 and a second positioning plate 8 is arranged on the second guide rail 4 to slide forward and backward along the right positioning plate 10. A second baffle 81 is arranged vertically at the rear end of the second positioning plate 8, and the width of the second baffle 81 is greater than the width of the right positioning plate 10.

[0026] A third guide rail 15 arranged longitudinally is fixed on the installation top surface 201 between the left positioning plate 9 and the right positioning plate 10. A positioning driving plate 16 sliding forward and backward along the third guide rail 15 is provided. The positioning driving plate 16 comprises a sliding portion 161 and a push-out portion 162 located at one end of the sliding portion 161. The push-out portion 162 is a T-shaped vertical plate. Both ends of the T-shaped vertical plate are provided with arc surfaces 1621 matching with the driving wheel 17. A cylinder mounting seat 18 is connected to the installation top surface 201 at the rear end of the third guide rail 15. A driving cylinder 19 is installed on the cylinder mounting seat 18. The push rod of the driving cylinder 19 is connected to the T-shaped vertical plate.

[0027] like Figure 5 As shown, the inner sides of the front and rear positioning surfaces and the inner sides of the left and right positioning surfaces of the U-shaped member are the positioning references of the positioning member. When working, the U-shaped member is loaded from the top of the positioning device. Because the front and rear positioning and left and right positioning margins of the positioning device of this embodiment are designed to be large, they are 5.5mm ( Figure 5 (a)) and 3mm ( Figure 5 (b)) reduces the position accuracy requirement for the U-shaped component when loading, and it is very convenient to put the U-shaped component into the positioning device of this embodiment, and there will be no problem of jamming or failure to put it in during the previous tooling positioning.

[0028] Specific working principle: When the U-shaped member is placed in the positioning device of this embodiment, the driving cylinder 19 pushes the positioning driving plate 16 to move forward along the third guide rail 15, driving the two driving wheels 17 to move forward, and the pushing part 162 pushes the driving wheel 17, so that the first positioning plate 7 and the second positioning plate 8 move forward along the first guide rail 3 and the second guide rail 4 respectively, while the left positioning plate 9 and the right positioning plate 10 move in the opposite direction along the left guide rail 5 and the right guide rail 6 respectively. The left and right positioning plates 9 and 10 are respectively applied with thrust, and the left return spring 13 and the right return spring 14 respectively apply thrust to the left and right positioning plates 9 and 10, and the thrust on the first and second return springs 11 and 12 is greater than the thrust on the left and right return springs 13 and 14. Therefore, when the driving cylinder 19 promotes the positioning movement, the left and right positioning plates 9 and 10 are first moved into position (the front and rear positioning surfaces of the U-shaped component) to position the U-shaped component left and right, and the left and right positioning plates 9 and 10 are moved into position and are respectively limited by the left and right positioning seats 1 and 2 to ensure accurate left and right positioning. When the left and right positioning seats 1 and 2 are limited and cannot move, the driving cylinder 19 continues to drive the left and right positioning plates 9 and 10 forward through the driving wheel 17. At this time, the left and right positioning plates 9 and 10 respectively drive the first and second positioning plates 7 and 8 to move backwards through the left guide rail 5 and the right guide rail 6 to complete the front and rear positioning of the U-shaped component. When the U-shaped component needs to be taken out, it is only necessary to drive the cylinder 19 to reset. At this time, the first reset spring 11, the second reset spring 12, the left reset spring 13 and the right reset spring 14 respectively push the first positioning plate 7, the second positioning plate 8, the left positioning plate 9 and the right positioning plate 10 to reset. At this time, the U-shaped component can be taken out to complete a positioning action.

[0029] The above-mentioned implementation mode is only for illustrating the technical concept and features of the utility model, and its purpose is to enable people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
