[0002] Special-shaped cross-section stainless steel profiles are a type of stainless steel material with a non-traditional cross-sectional shape. Their special design can meet various customized requirements. Such profiles have high strength, corrosion resistance, and durability, and are widely used in fields such as architectural decoration, machinery manufacturing, and transportation, giving projects a unique appearance and providing excellent structural support.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] As Figures 1 - 4As shown in the figure, the utility model provides a technical solution: a special-shaped stainless steel profile grinding and positioning tooling, including a base 1.

A lower fixture 9 is fixedly connected to the side of the mounting seat 5 close to the clamping cylinder 7. The upper fixture 8 is fixedly connected to the output end of the clamping cylinder 7 by bolts. The lower fixture 9 is fixedly connected to the fixing plate 6 by bolts.

The top of the workpiece 10 is in contact with the upper fixture 8.

[0026] The slide rail 11 is fixedly connected to the top end face of the base 1. A tailstock 12 is slidably connected to the slide rail 11. A rotating rod 13 is sleeved on the side wall of the tailstock 12. A clutch-synchronization locking mechanism 19 is arranged on the side wall of the rotating rod 13. The clutch-synchronization locking mechanism 19 is fixedly connected to the inner wall of the tailstock 12. A bearing 14 is fixedly connected to the side wall of the rotating rod 13. The bearing 14 includes an inner ring, an outer ring, and steel balls. The inner ring is fixedly connected to the rotating rod 13. The outer ring is fixedly connected to the inner wall of the tailstock 12. The inner ring and the outer ring are movably connected by the steel balls. A turntable 4 is fixedly connected to the side wall of the rotating rod 13. A mounting seat 5 is fixedly connected to the side wall of the turntable 4. A fixing plate 6 is fixedly connected to the outer wall of the turntable 4. One end of the fixing plate 6 away from the front seat 2 is fixedly connected to a clamping cylinder 7. The output end of the clamping cylinder 7 is fixedly connected to an upper fixture 8. A lower fixture 9 is fixedly connected to the side of the mounting seat 5 close to the clamping cylinder 7. The two ends of the special-shaped stainless steel profile are clamped by the upper fixture 8 and the lower fixture 9 to fix the special-shaped stainless steel profile.

[0027] The mounting bracket 15 is fixedly connected to the top end face of the base 1. A lift 16 is fixedly connected to the top end face of the mounting bracket 15. The output end of the lift 16 is fixedly connected to a connecting rod 17. The top end face of the connecting rod 17 is fixedly connected to a top rod 18. The connecting rod 17 and the top rod 18 are made of stainless steel profiles. The connecting rod 17 and the top rod 18 are fixedly connected by bolts. The connecting rod 17 and the output end of the lift 16 are fixedly connected by bolts. The number of the top rods 18 is set to several groups. Several groups of top rods 18 are fixedly connected to the top end face of the connecting rod 17 at equal intervals. The top of the top rod 18 is in contact with the special-shaped stainless steel profile to support the special-shaped stainless steel profile.

[0028] The upper clamp 8 and the clamping cylinder 7 are fixed together by bolts. The lower clamp 9 is fixed on the mounting seat 5. The clamping cylinder 7 pushes the upper clamp 8 to move the upper clamp 8 downward. The upper clamp 8 and the lower clamp 9 clamp the workpiece 10. The upper clamp 8 and the lower clamp 9 are designed according to a workpiece 10 with a certain cross-section. By manually replacing the clamps, the clamping of different special-shaped stainless steel profiles can be realized, preventing the loosening of the profiles during the grinding process.

[0029] Since the lengths of the profiles are different, by sliding the tailstock 12, the distance between the front seat 2 and the tailstock 12 is adjusted, thereby realizing the clamping of the head and tail ends of the profiles and meeting the requirements of workpieces 10 with different lengths.

[0030] When grinding the workpiece 10, due to the action of the grinding force, the workpiece 10 has a tendency to rotate. By fixedly connecting a clutch-synchronization locking mechanism 19 inside the tailstock 12, when the servo motor 3 is not working, the rotating rod 13 is automatically locked through the PLC control system, keeping the two ends of the workpiece 10 in the same plane, ensuring the flatness of the grinding surface and improving the grinding effect.

[0031] After grinding one side, the servo motor 3 drives the rotating shaft and the turntable 4, and then drives the workpiece 10 to rotate, realizing the precise rotation of the workpiece 10 and achieving the function of grinding multiple planes with one clamping.

[0032] It should be noted that the clamping cylinder 7 is controlled by the PLC system to clamp the workpiece 10. When the PLC control system drives the servo motor 3 to rotate the workpiece 10 for precise rotation of the workpiece 10, it simultaneously controls the clutch-synchronization locking mechanism 19 to unlock the rotating rod 13, enabling the rotating rod 13 to also rotate synchronously, realizing the surface-changing grinding of the workpiece 10.

[0033] In addition, the mounting bracket 15 is fixedly connected to the top end face of the base 1. The top end face of the mounting bracket 15 is fixedly connected with a lift 16. The output end of the lift 16 is fixedly connected with a connecting rod 17. The top end face of the connecting rod 17 is fixedly connected with a jacking rod 18. During grinding, the grinding device applies a downward pressure to the workpiece 10. When the workpiece 10 is too long, the workpiece 10 will deform. The workpiece 10 is jacked up by the jacking rod 18 to maintain the relative stability of the force. When the servo motor 3 drives the workpiece 10 to rotate, the PLC control system drives the lift 16 to descend, so that the workpiece 10 can rotate normally. When the workpiece 10 rotates to the in-place position, the PLC control system then pushes the connecting rod 17 and the jacking rod 18 to move upward, so that the jacking rod 18 forms a support for the workpiece 10. Through the liftable support device, at different cross-sectional widths of the workpiece 10, the height of the support point position of the support rod on the workpiece 10 automatically rises and falls to provide a stable support force.

[0034] In the present utility model, during use, the distance between the front seat 2 and the tail seat 12 is adjusted. The clamping cylinder 7 pushes the upper clamp 8 downward through the push rod, so that the upper clamp 8 moves downward. The upper clamp 8 and the lower clamp 9 clamp the workpiece 10. When the servo motor 3 does not work, the rotating rod 13 is automatically locked through the PLC control system. After one side of the workpiece 10 is ground, the servo motor 3 drives the rotating shaft and the turntable 4, thereby driving the workpiece 10 to rotate for precise rotation of the workpiece 10. Further, when the servo motor 3 drives the workpiece 10 to rotate, the PLC control system drives the lift 16 to descend. After the workpiece 10 rotates to the in-place position, the PLC control system then pushes the connecting rod 17 and the jacking rod 18 to move upward, and the jacking rod 18 jacks up the workpiece 10 to provide support for the workpiece 10.

[0035] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present utility model are all within the protection scope of the present utility model.
