Description

Technical Field

[0001] This utility model relates to the field of pneumatic locking technology, specifically a pneumatic mechanical locking device. Background Technology

[0002] Pneumatic locking devices are a common type of mechanical transmission control device. Their main principle is to use air pressure to press the locking components, thereby achieving the locking effect. At the same time, they can quickly lock and unlock through air pressure transmission, which greatly improves work efficiency.

[0026] like Figures 1 to 5 As shown, a locking device for pneumatic machinery includes a locking device base 1, a fixing plate 2 fixedly connected to the upper side of the locking device base 1, and a cylinder 3 fixedly mounted on the left side of the fixing plate 2. The cylinder 3 is connected to compressed air, so that the cylinder 3 converts the pressure of the compressed air into mechanical energy, driving the mechanism to achieve reciprocating linear motion, so as to lock or release the workpiece. It has good stability and is easy to use. A bracket 4 is fixedly installed on the left side of the cylinder 3, a first fixing frame 5 is fixedly mounted on the upper side of the locking device base 1, and a second fixing frame 6 is fixedly mounted on the left side of the bracket 4.

[0027] A telescopic plate 7 is slidably installed on the left side of the second fixed frame 6. A first spring 8 is connected in an array between the telescopic plate 7 and the second fixed frame 6. A rotating shaft seat 9 is rotatably connected to the inner side of both the first fixed frame 5 and the telescopic plate 7. One side of the rotating shaft seat 9 passes through the first fixed frame 5 and extends to the left side of the first fixed frame 5. A driven gear 11 is fixedly connected to the left side of the rotating shaft seat 9. A driven gear 11 is rotatably installed on the left side of the first fixed frame 5. The driven gear 11 meshes with the gear rod 10.

[0028] The interior of the two pivot seats 9 is respectively fixed with a first U-shaped seat 17 and a second U-shaped seat 19. The inner sides of the two pivot seats 9 are slidably connected with two movable clamping plates 14 for fixing the first U-shaped seat 17 and the second U-shaped seat 19. The four movable clamping plates 14 are fixedly connected with the pivot seats 9 with a second spring 16. One side of the pivot seat 9 passes through the pivot seat 9 and extends to one side of the pivot seat 9. The side of each of the four movable clamping plates 14 is fixedly provided with a side plate 15.

[0029] The inner side of the first U-shaped seat 17 is connected with an array of rubber clamps 18, and the inner side of the second U-shaped seat 19 is fixedly installed with a fixing seat 20. A movable clamping plate 14 can be used to clamp and fix the first U-shaped seat 17, allowing for easy replacement of rubber clamps 18 and fixing seats 20 of different sizes to adapt to and lock workpieces of different sizes, thus improving the applicability of the locking device. A plug plate 21 is snapped into one side of the fixing seat 20, and a rubber pad 22 is fixedly installed on one side of the fixing seat 20. The rubber pad 22 can be used to... To protect and lock the workpiece, and to make the fixed seat 20 more stable in positioning the workpiece, both ends of the fixed seat 20 are fixedly connected to baffles 23. The baffles 23 can be used to limit the movement of the workpiece and prevent it from shifting. Both ends of the first U-shaped seat 17 and the second U-shaped seat 19 are fixedly provided with handles 24. The upper side of the telescopic plate 7 is fixedly connected to a support plate 29. The upper side of the support plate 29 is engaged with a pin 30 for fixing the rotating shaft seat 9. The pin 30 can be used to fix the rotating shaft seat 9 and prevent the rotating shaft seat 9 from rotating freely.

[0030] A connecting plate 25 is fixedly connected to the left side of the first fixed frame 5. A bolt 26 is threadedly connected to one side of the connecting plate 25. A U-shaped limiting plate 27 for positioning the operating handwheel 12 is fixedly connected to one side of the bolt 26. Rotating the bolt 26 can drive the U-shaped limiting plate 27 to move closer to the operating handwheel 12 to lock the operating handwheel 12 and ensure the stability of the entire rotating shaft seat 9. One side of the bolt 26 passes through the connecting plate 25 and extends to the other side of the connecting plate 25. Two smooth rods 28 are fixedly installed on one side of the U-shaped limiting plate 27. The outer surfaces of the two smooth rods 28 are slidably connected to the inside of the connecting plate 25. The smooth rods 28 can be used to limit the movement trajectory of the U-shaped limiting plate 27 in order to position the operating handwheel 12.

[0031] The second fixed frame 6 is located to the right of the first fixed frame 5. One side of the telescopic plate 7 passes through the second fixed frame 6 and extends to the right side of the second fixed frame 6. The left side of the gear rod 10 is fixedly connected to the operating handwheel 12. Two symmetrically arranged guide plates 13 are fixedly installed on the upper side of the locking device base 1. The guide plates 13 are located below the second fixed frame 6. By setting the guide plates 13, the movement direction of the second fixed frame 6 can be limited by the two guide plates 13, so that the second fixed frame 6 can smoothly drive the workpiece to move back and forth, so as to lock the workpiece.

[0032] The inside of the rotating shaft seat 9 is provided with a round hole 66, which is adapted to the pin 30. The outer surface of the pin 30 is engaged with the inside of the rotating shaft seat 9 through the round hole 66.

[0033] The working principle of the locking device for pneumatic machinery provided by this utility model is as follows:

[0034] All workpieces are placed sequentially onto the insert plate 21 at the fixed seat 20. Then, the cylinder 3 drives the second fixed frame 6 to move to the left along the two guide plates 13. This drives the workpiece to fit against the first U-shaped seat 17. At this time, the rubber clamp 18 at the first U-shaped seat 17 can squeeze and position the workpiece to lock it and ensure the stability of the workpiece during processing. Then, the pin 30 is pulled out from the rotating shaft seat 9 to release the limit on the rotating shaft seat 9. Then, the operating handwheel 12 is turned to drive the gear rod 10 to rotate. In this way, the gear rod 10 can drive the driven gear 11 to rotate, causing the two rotating shaft seats 9 to rotate so that the bottom of the workpiece can be flipped to the top. Then, the insert plates 21 are pulled out to better display the workpiece for further processing. This saves time and effort, eliminates the need to re-lock the workpiece, reduces the workload of the operator, and improves the clamping efficiency of the locking device.

[0035] By utilizing the array of rubber clamps 18 on the first U-shaped seat 17 and the array of fixed seats 20 on the second U-shaped seat 19, all workpieces can be clamped and locked simultaneously using pneumatic mechanical means. This not only makes operation convenient but also reduces manual intervention and greatly improves work efficiency. Furthermore, the telescopic plate 7 equipped with the first spring 8 can act as a buffer, and the elasticity of the first spring 8 can be used to weaken the impact force of the cylinder 3, thereby protecting the locked workpieces, preventing damage to the workpieces from the impact force, and ensuring the safety of the locking device.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
