[0031] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a sheet positioning device, including an operating table 1, a first positioning column 3 is erected on one side at the middle position of the upper surface of the operating table 1, and a second positioning column 4 is erected on the other side at the middle position of the upper surface of the operating table 1. The first positioning column 3 and the second positioning column 4 are used to position the two sides of a plurality of leaf spring alloys. Specifically, a fixing block 6 is fixed at a position close to the second positioning column 4 on the operating table 1, and a tightening screw 7 is threaded through the fixing block 6. The tightening screw 7 is rotatably connected to the second positioning column 4. The tightening screw 7 is screwed to push the second positioning column 4 toward the two first positioning columns 3, so that the two sides of the plurality of leaf spring alloys can be tightened and positioned. In addition, there are two first positioning columns 3, and the two first positioning columns 3 are symmetrically distributed with the second positioning column 4 as the central axis. The structural mode in which the two first positioning columns 3 are symmetrically arranged with the second positioning column 4 as the axis can adapt to the plurality of leaf spring alloys with a curved structure, and the tightening effect on the two sides of the plurality of leaf spring alloys is better.

[0032] In this embodiment, if Figure 1 , Figure 2 and Figure 3As shown, end positioning mechanisms 2 are provided at both ends of the operating table 1 for positioning the two ends of a plurality of spring alloys. Specifically, the end positioning mechanism 2 includes a push plate 12 arranged along the width direction of the operating table 1 and a positioning plate 13 arranged perpendicular to the push plate 12. Both sides of the operating table 1 are provided with a driving mechanism 8 for driving a pair of push plates 12 to move closer to each other. A plurality of positioning plates 13 are provided and are all located on the opposite side of a pair of push plates 12. The plurality of positioning plates 13 fit each other. The plurality of positioning plates 13 are used to position each spring alloy individually. A connecting arm 18 is provided at one end of the positioning plate 13 away from the middle of the operating table 1. The connecting arm 18 passes through the push plate 12 and a stopper 19 is fixed at the end. A plurality of adjustment blocks 20 of the same size are sleeved on the connecting arm 18. By using this structural method, by adjusting the adjustment block 20 on each connecting arm 18, The number of the two sides of the push plate 12 controls the distance between the positioning plate 13 and the push plate 12 at one end of the middle of the operating table 1. By using this adjustment method, a length difference can be formed at one end of the multiple positioning plates 13 toward the middle of the operating table 1 to adapt to the length difference of several spring alloys. Subsequently, a pair of push plates 12 are driven to approach each other through the driving mechanism 8. The multiple positioning plates 13 on each push plate 12 can independently tighten and limit the ends of several spring alloys. Therefore, on the basis of tightening and limiting the two sides of several spring alloys by the two first positioning columns 3 and the second positioning columns 4, the two ends of several spring alloys can be independently tightened and limited by multiple positioning plates 13 with length difference, thereby realizing all-round positioning of several spring alloys, enhancing the positioning effect of several spring alloys, and making it more convenient for staff to assemble several positioned spring alloys into leaf springs.

[0033] In this embodiment, if Figure 2 , Figure 3 and Figure 4 As shown, the walls of the adjustment block 20 are flush with the surface of the positioning plate 13. The adjustment block 20 is provided with a slot 21 for the connecting arm 18 to be inserted. The slot 21 penetrates the bottom end surface of the adjustment block 20. The multiple positioning plates 13 on the same push plate 12 are connected with connecting bolts 14 to ensure that the multiple positioning plates 13 can fit tightly. The positioning plate 13 is provided with a through slot 17 for the connecting bolt 14 to pass through. The through slot 17 is provided along the length direction of the positioning plate 13. The through slot 17 can be still connected by the connecting bolt 14 after the multiple positioning plates 13 are adjusted. The push plate 12 is provided with a slide slot 15 for the connecting arm 18 to pass through. The slide slot 15 is provided along the length direction of the push plate 12 and is used to adjust the horizontal position of the multiple positioning plates 13 so that after the two sides of the multiple spring alloys are positioned, the multiple positioning plates 13 can be aligned with the ends of the multiple spring alloys.

[0034] In this embodiment, if Figure 1 , Figure 2As shown, the driving mechanism 8 includes a pair of bidirectional screw rods 9 installed on both sides of the operating table 1, and sleeve blocks 16 are provided at both ends of most push plates 12. The sleeve blocks 16 are threadedly sleeved with the bidirectional screw rods 9, and a transmission belt 11 is sleeved between the ends of a pair of bidirectional screw rods 9. A driving motor 10 for driving one of the bidirectional screw rods 9 to rotate is installed at the end of the operating table 1. The driving motor 10 is started, and the two bidirectional screw rods 9 are driven to rotate under the transmission of the transmission belt 11. The threaded cooperation between the bidirectional screw rods 9 and the sleeve blocks 16 is used to drive a pair of push plates 12 to move closer to each other, so that the ends of several leaf spring alloys can be pressed and positioned by using multiple positioning plates 13 on the push plates 12; a plurality of operating slots 5 are opened on the operating table 1, and the operating slots 5 vertically penetrate the operating table 1. After several leaf spring alloys are positioned, the staff can use the operating slots 5 to sleeve and combine several leaf spring alloys to form leaf springs.

[0035] The technical solution provided by the utility model is that when in use, a plurality of spring alloy sheets are stacked between the two first positioning posts and the second positioning posts on the operating table, wherein the arched side of the plurality of spring alloy sheets is placed toward the two first positioning posts, and then the tightening screw is screwed to push the second positioning post toward the two first positioning posts until the second positioning post tightens the plurality of spring alloy sheets, and then multiple positioning plates are adjusted, specifically, the adjusting blocks sleeved on the connecting arm corresponding to each positioning plate are adjusted, and the distance between the positioning plate and the push plate at one end toward the middle of the operating table is controlled by adjusting the number of adjusting blocks on both sides of the push plate on each connecting arm, and the adjustment method is used to form a length of the plurality of positioning plates at one end toward the middle of the operating table. The difference is used to adapt to the length difference of several pieces of spring alloy. After the positioning plate is adjusted, the driving motor is started to drive the two bidirectional lead screws to rotate under the drive of the transmission belt, and the threaded cooperation of the bidirectional lead screw and the sleeve block is utilized to drive a pair of push plates to move closer to each other. At this time, the multiple positioning plates on each push plate can independently tighten and limit the ends of several pieces of spring alloy. As a result, the two sides of several pieces of spring alloy are tightened and limited by the two first positioning columns and the second positioning columns, and the two ends of several pieces of spring alloy are independently tightened and limited by multiple positioning plates with length difference, thereby realizing all-round positioning of several pieces of spring alloy. The staff only needs to use the operating slot to put several pieces of positioned spring alloy together to form a leaf spring.
