Abstract

This utility model discloses a stable tooling fixture for precision parts machining, including a base plate. A mounting platform is movably connected to the top of the base plate, and the centerline of the mounting platform is on the same vertical plane as the centerline of the base plate. The mounting platform has a clamping structure inside to improve workpiece stability. This stable tooling fixture for precision parts machining works by placing the workpiece on the top of the mounting platform before machining. Then, an electric cylinder inside the mounting platform is activated, which pushes a set of connecting plates to one side. The connecting plates drive a transmission plate, which in turn drives a transmission gear through a second toothed block. Simultaneously, the transmission gear, through the second toothed blocks in each direction, drives each set of transmission plates to move. Finally, the transmission plate, through the connecting plates and connecting blocks, moves the top sliding plate and positioning clamping plate, causing the positioning clamping plate to fit against the outside of the workpiece for positioning. This solves the problem of insufficient workpiece positioning stability.

[0025] Example: Please refer to Figure 1-4 A stable tooling fixture for precision parts processing includes a base plate 1, a mounting platform 2 movably connected to the top of the base plate 1, the center line of the mounting platform 2 and the center line of the base plate 1 being on the same vertical plane, and a clamping structure for improving workpiece stability being provided inside the mounting platform 2.

[0026] The clamping structure includes a transmission gear 7. The transmission gear 7 is movably connected to the top of the mounting platform 2. A set of sliding grooves 19 are opened on both sides and both ends of the top of the mounting platform 2. A set of sliding plates 4 are movably connected to both sides and both ends of the top of the mounting platform 2. A positioning clamping plate 6 is fixedly connected to the top of the sliding plate 4. A set of connecting plates 11 are movably connected to both sides and both ends of the top of the mounting platform 2. A transmission plate 12 is fixedly connected to one side of the connecting plate 11. A second tooth block 23 is fixedly connected to one end of the transmission plate 12. A connecting block 20 is fixedly connected to the top of the connecting plate 11. An electric cylinder 3 is fixedly connected to the right side of the mounting platform 2.

[0027] The connecting block 20 is fixedly connected to the slide plate 4 through the slide groove 19, and the connecting block 20 is slidably connected to the slide groove 19.

[0028] The second tooth block 23 meshes with the transmission gear 7, and the output end of the electric cylinder 3 is fixedly connected to the connecting plate 11.

[0029] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, before processing, the parts are placed on the top of the mounting platform 2. Then, the electric cylinder 3 inside the mounting platform 2 is activated. The electric cylinder 3 can push a set of connecting plates 11 to move to one side. The connecting plates 11 drive the transmission plates 12 to move, which can drive the transmission gear 7 to rotate through the second tooth block 23. While the transmission gear 7 is rotating, it drives each set of transmission plates 12 to move through the second tooth blocks 23 in each direction. Finally, the transmission plates 12 drive the top slide plate 4 and positioning clamp 6 to move through the connecting plates 11 and connecting blocks 20, so that the positioning clamp 6 fits against the outside of the parts to position them. This realizes that the parts can be positioned from multiple angles to improve positioning stability.

[0030] A connecting ring 14 is fixedly connected to the top of the base plate 1. A first toothed block 13 is fixedly connected inside the connecting ring 14. A fixed cylinder 8 is fixedly connected to the left side of the top of the mounting platform 2. A drive motor 9 is fixedly connected inside the fixed cylinder 8. A drive gear 18 is fixedly connected through the bottom end of the fixed cylinder 8 at the output end of the drive motor 9. A fixed ring 10 is fixedly connected to the top of the base plate 1. A first annular groove 15 is opened inside the fixed ring 10. A second annular groove 17 is opened at the bottom of the outside of the mounting platform 2. A ball bearing 16 is movably connected inside the second annular groove 17.

[0031] The drive gear 18 is meshed with the first tooth block 13, and the ball 16 is movably connected to the first annular groove 15.

[0032] The center line of the connecting ring 14 and the center line of the mounting platform 2 are on the same vertical plane, and the center line of the fixing ring 10 and the center line of the mounting platform 2 are on the same vertical plane;

[0033] Specifically, such as Figure 1 and Figure 2 As shown, during processing, the drive motor 9 inside the fixed cylinder 8 can be started to drive the drive gear 18 to rotate. At the same time, the drive gear 18 rotates and, in conjunction with the first tooth block 13, can drive the mounting table 2 to rotate in the opposite direction. This allows the components on top of the mounting table 2 to rotate, so as to quickly adjust the angle of the components. Furthermore, the fixing ring 10 at the top of the base plate 1 can support the mounting table 2 through the ball bearings 16 and ensure the stability of the mounting table 2 when it rotates, thus enabling the adjustment of the component angle after positioning.

[0034] The top of the mounting platform 2 is provided with a groove 21, a rubber pad 5 is fixedly connected inside the groove 21, and positioning blocks 22 are fixedly connected to both sides and both ends inside the groove 21.

[0035] Positioning block 22 is fixedly connected to rubber pad 5, and the center line of groove 21 is on the same vertical plane as the center line of mounting platform 2;

[0036] Specifically, such as Figure 1 and Figure 3 As shown, a groove 21 is provided at the top of the tooling mounting table 2, and a rubber pad 5 is installed inside the groove 21. After the parts are positioned, the rubber pad 5 adheres to the bottom of the parts, which can effectively increase the friction and prevent the parts from rotating during processing. In addition, the positioning block 22 inside the groove 21 can improve the firmness of the rubber pad 5, thereby further improving the stability of the rubber pad 5 and realizing the prevention of parts from rotating during processing.

[0037] Working Principle: Before processing, the parts are placed on the top of the mounting platform 2. Then, the electric cylinder 3 inside the mounting platform 2 is activated. The electric cylinder 3 pushes a set of connecting plates 11 to one side. The connecting plates 11 drive the transmission plate 12, which in turn drives the transmission gear 7 to rotate via the second toothed block 23. Simultaneously, the rotation of the transmission gear 7 drives the transmission plates 12 to move via the second toothed blocks 23 in each direction. Finally, the transmission plate 12, through the connecting plates 11 and connecting blocks 20, drives the top sliding plate 4 and positioning clamp 6 to move, causing the positioning clamp 6 to fit against the outside of the parts for positioning. During processing, the drive motor 9 inside the fixed cylinder 8 is activated to drive the drive gear 18 to rotate. While the drive gear 18 rotates, it works in conjunction with the first tooth block 13 to drive the mounting platform 2 to rotate in the opposite direction. This causes the components on top of the mounting platform 2 to rotate, allowing for quick adjustment of the component angles. The fixing ring 10 at the top of the base plate 1 supports the mounting platform 2 via ball bearings 16, ensuring the stability of the mounting platform 2 during rotation. A groove 21 is provided at the top of the tooling mounting platform 2, and a rubber pad 5 is installed inside the groove 21. After the component is positioned, the rubber pad 5 adheres to the bottom of the component, effectively increasing friction and preventing the component from rotating during processing. Furthermore, the positioning block 22 inside the groove 21 enhances the firmness of the rubber pad 5, further improving its stability.
