Description

Technical Field

[0001] This utility model relates to the field of clamping technology, specifically a novel pneumatic quick clamp. Background Technology

[0002] A fixture is a device used in mechanical manufacturing to fix a workpiece in the correct position for operation or inspection; it is also called a clamp. In a broader sense, any device used to quickly, conveniently, and safely install a workpiece at any stage of the manufacturing process can be called a fixture. A fixture typically consists of positioning elements, clamping devices, tool setting guide elements, indexing devices, connecting elements, and a fixture body.

[0003] There are many types of clamps, and pneumatic quick clamps are one of them. For example, Chinese Patent discloses a new type of pneumatic quick clamp, Publication (Announcement) No.: CN204657977U, which includes a two-way cylinder, pressure plates, pins, supports, bases, and tension springs. The base is a hollow cylinder, and the two-way cylinder is located in the internal cavity of the base. The two piston rods of the two-way cylinder extend to the left and right sides, and the extended ends of the two piston rods abut against the pressure plates on the left and right sides, respectively. The pressure plates on both sides are fixed to the supports by pins, and the supports are fixedly connected to the base. The pressure plates on both sides are placed opposite each other, and the upper ends of the pressure plates on both sides are hook-shaped, which cooperate with the pads to clamp the workpiece. The lower ends of the pressure plates on both sides are connected by tension springs. This invention facilitates automated control by introducing a bidirectional cylinder to participate in the workpiece clamping action. Because the bidirectional cylinder drives the two side pressure plates to clamp the workpiece, it features high clamping force, safety, reliability, and rapid operation. Furthermore, the presence of return springs at the lower ends of the two side pressure plates facilitates fixture reset, thereby shortening clamping time and improving production efficiency. While the aforementioned patent facilitates fixture reset during use, thus shortening clamping time and improving production efficiency, it lacks cushioning for the clamping plates. This can lead to the clamping plates making hard contact with the workpiece during rapid clamping, potentially damaging the workpiece and causing inconvenience for the user, thus affecting normal operation.

[0023] like Figures 1 to 3As shown, this utility model provides a novel pneumatic quick clamp, comprising:

[0024] Chassis 1;

[0025] Inflation mechanism 2 is provided on both sides of the casing 1;

[0026] The pneumatic clamping mechanism 3 includes a pneumatic sleeve 31, which is disposed on both sides of the housing 1. A piston 32 is slidably connected to the inner wall surface of the pneumatic sleeve 31. A movable disk 33 is fixedly connected to the inner side of the piston 32.

[0028] As a technical optimization of this utility model, by setting the chassis 1, the pneumatic clamping mechanism 3 can be supported. The user fixes the power supply device 102 on the top of the base plate 101, then fixes the top plate 103 on the top of the power supply device 102, and then fixes the protective plate 104 on both sides of the top of the top plate 103, so that the pneumatic clamping mechanism 3 can be supported by the protective plate 104.

[0029] refer to Figure 2 The inflation mechanism 2 includes an inflator 21, which is movably connected to both sides of the bottom of the base plate 101. The inflation end of the inflator 21 is connected to a connecting pipe 22. The end of the connecting pipe 22 away from the inflator 21 is connected to a transmission pipe 23. The end of the transmission pipe 23 away from the connecting pipe 22 is connected to the pneumatic sleeve 31.

[0030] As a technical optimization of this utility model, by setting an inflation mechanism 2, the inside of the pneumatic sleeve 31 can be inflated. The user drives the inflation machine 21, and the inflation machine 21 transmits the gas into the inside of the connecting pipe 22 through the inflation end. The connecting pipe 22 transmits the gas into the inside of the transmission pipe 23, so that the transmission pipe 23 transmits the gas into the inside of the pneumatic sleeve 31 to inflate the pneumatic sleeve 31.

[0031] refer to Figure 1 Both sides of the pneumatic sleeve 31 are fixedly connected to a stabilizing plate 4, and the bottom of the stabilizing plate 4 is fixedly connected to the top of the protective plate 104.

[0032] As a technical optimization of this utility model, by setting a stabilizing plate 4, the pneumatic sleeve 31 can be fixed to prevent the pneumatic sleeve 31 from shaking.

[0033] refer to Figure 3 The top and bottom of the movable disk 33 are fixedly connected to guide plates 5. The side of the guide plate (5) away from the movable disk 33 is slidably connected to the inside of the pneumatic sleeve 31. The top and bottom of the inner wall of the stabilizing sleeve 35 are provided with grooves 6. The inside of the grooves 6 is slidably connected to sliders 7. The inner side of sliders 7 is fixedly connected to sliding plates 38.

[0034] As a technical optimization of this utility model, by setting the guide plate 5, the movable disk 33 can be fixed to prevent the movable disk 33 from rotating. By setting the slide groove 6 and the slider 7, the stabilizing sleeve 35 can be limited to prevent the stabilizing sleeve 35 from rotating.

[0035] refer to Figure 2 The inflator 21 has upright plates 8 fixedly connected to both sides of the front and back sides. The bottom of the upright plate 8 is fixedly connected to the top of the base plate 101, and the top of the upright plate 8 is fixedly connected to the bottom of the top plate 103. Bolts 9 are provided at the top and bottom of the front of the upright plate 8. The end of the bolt 9 near the upright plate 8 passes through the upright plate 8 and extends into the interior of the inflator 21.

[0036] As a technical optimization of this utility model, by setting the upright plate 8 and the bolt 9, the air inflator 21 can be positioned to prevent the air inflator 21 from shaking.

[0037] The working principle and usage process of this utility model are as follows: During use, the user drives the inflator 21. The inflator 21 transmits gas through the inflation end into the connecting pipe 22, which in turn transmits the gas into the transmission pipe 23. The transmission pipe 23 then transmits the gas into the pneumatic sleeve 31, inflating it. This increased internal air pressure pushes the piston 32 inwards, causing the piston 32 to move the moving disc 33 inwards. The inward movement of the moving disc 33 compresses the second buffer spring 37, which in turn compresses the moving disc 33. The moving speed is buffered, and at the same time, the moving disk 33 drives the connecting rod 34 to move inward. The connecting rod 34 drives the stabilizing sleeve 35 to move inward. The stabilizing sleeve 35 drives the T-shaped clamp 39 to move inward and contact the workpiece through the buffer spring 36 and the sliding plate 38 to clamp the workpiece. At the same time, when the T-shaped clamp 39 clamps the workpiece, the T-shaped clamp 39 compresses the buffer spring 36 through the sliding plate 38 and moves inward. The buffer spring 36 and the sliding plate 38 provide secondary buffering for the T-shaped clamp 39 to avoid hard contact between the T-shaped clamp 39 and the workpiece.

[0038] In summary, this novel pneumatic quick clamp, by setting up an inflation mechanism 2, can inflate the pneumatic clamping mechanism 3. By setting up the pneumatic clamping mechanism 3, the workpiece can be quickly clamped while providing cushioning. During the quick clamping, the clamping plate will not make hard contact with the workpiece, avoiding damage to the workpiece and making it convenient for the user to use, thus ensuring normal operation.
