[0024] Please see Figure 1-4This utility model provides an embodiment of an automatic tapping and positioning device for sheet metal parts used in high-speed rail, comprising a positioning seat 1, a reserved groove 2 inside the positioning seat 1, an adjusting screw 7 movably mounted inside the reserved groove 2, a servo motor 17 mounted on the right side inside the reserved groove 2, two sets of screw sleeves 16 mounted outside the adjusting screw 7, a support plate 3 fixedly connected to the top of the screw sleeves 16, clamping plates 15 on both sides of the top of the positioning seat 1, a groove 13 at the top of the support plate 3, and a drive motor mounted inside the groove 13. The output end of the drive motor 12 is fixedly connected to the support base 11. The top of the support base 11 is equipped with an electric push rod 5. The output end of the electric push rod 5 is fixedly connected to the fixing plate 6. The top of the fixing plate 6 is equipped with a hydraulic cylinder 10. The output end of the hydraulic cylinder 10 is equipped with a splicing groove 22. The bottom end of the splicing groove 22 is equipped with a positioning plate 9. A clamping pad 19 is provided on the clamping plate 15. An installation block 14 is fixedly connected to the outside of the clamping plate 15. An installation slot 4 is provided inside the support plate 3. An installation bolt 18 is provided at the front end of the support plate 3.

[0025] The positioning plate 9 is provided with two sets. A rubber pad is installed at the bottom of the positioning plate 9. The bottom of the reserved groove 2 is fixedly connected to the limit slide 8. The screw sleeve 16 is slidably connected to the outside of the limit slide 8. The output end of the servo motor 17 is fixedly connected to the right side of the adjusting screw 7. The adjusting screw 7 is provided with two sets of opposite threads on the outside.

[0026] Specifically, such as Figure 1 and Figure 4 As shown, during tapping, the servo motor 17 drives the clamping plate 15 to clamp and limit the sheet metal part. Then, the drive motor 12 drives the electric push rod 5 to rotate to a suitable limit angle. Then, the electric push rod 5 pushes the positioning plate 9 to the tapping area. Then, the hydraulic cylinder 10 pushes the positioning plate 9 downward. The positioning plate 9 is larger than the top of the sheet metal part to limit it.

[0027] The mounting block 14 is embedded inside the mounting slot 4. The mounting block 14 has a mounting hole 24 inside. The mounting bolt 18 is embedded inside the mounting hole 24. The top of the positioning seat 1 has a sliding groove. The two sides of the positioning seat 1 are fitted with fixing bolts 20.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, the clamping plate 15 can clamp and limit the side of the sheet metal part. When clamping, the clamping pad 19 on the clamping plate 15 can improve the clamping stability. The clamping plate 15 can be disassembled and replaced as needed. When replacing, unscrew the fixing bolt 20 and then remove the clamping plate 15 from the support plate 3. This structure realizes the function of easy replacement of the clamping plate 15.

[0030] Specifically, such as Figure 1 and Figure 3 As shown, the positioning plate 9 can be removed from the hydraulic cylinder 10. When removing it, the limiting baffle 21 needs to be moved away from the front end of the splicing block 23 first. After the limiting baffle 21 is moved away, the positioning plate 9 is pulled forward. The splicing block 23 on the top of the positioning plate 9 can then be moved out of the splicing groove 22.

[0031] Working Principle: In use, the positioning seat 1 is first installed on the tapping equipment, and then fixed using fixing bolts 20. The high-speed rail sheet metal part to be tapped is then placed on the positioning seat 1. During tapping, the servo motor 17 drives the adjusting screw 7 to rotate. The screw sleeve 16 outside the adjusting screw 7 drives the support plate 3 and clamping plate 15 to clamp and limit the sheet metal part. Then, the drive motor 12 drives the electric push rod 5 to rotate to a suitable limiting angle. The electric push rod 5 then pushes the positioning plate 9 to the tapping area. Subsequently, the hydraulic cylinder 10 pushes the positioning plate 9 downwards until it is larger than the top of the sheet metal part, thus limiting its position. Positioning plate 9 can be removed from hydraulic cylinder 10. When removing it, the limiting baffle 21 needs to be moved away from the front end of splicing block 23 first. After the limiting baffle 21 is moved away, the positioning plate 9 is pulled forward. The splicing block 23 on the top of the positioning plate 9 can be moved out from the splicing groove 22. Clamping plate 15 can clamp and limit the side of sheet metal parts. When clamping, the clamping pad 19 on clamping plate 15 can improve clamping stability. Clamping plate 15 can be disassembled and replaced as needed. When replacing, unscrew the fixing bolt 20 and then remove clamping plate 15 from support plate 3. This structure realizes the function of easy replacement of clamping plate 15 and improves the flexibility of clamping.
