Description

Technical Field

[0001] This utility model relates to the field of pneumatic chuck technology, and in particular to a double-sided clamping pneumatic chuck. Background Technology

[0002] When processing metal pipes and profiles using laser pipe cutting machines or integrated plate and pipe machines, positioning devices are required for fixing and clamping.

[0003] With the continuous improvement of pipe cutting machine design, the requirements for the stability and reliability of clamping force during pipe processing are becoming increasingly stringent. Traditional positioning devices often use a chuck for clamping. This can easily lead to pipe ejection during clamping, causing deviations in pipe processing and significantly impacting processing accuracy. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a double-sided pneumatic chuck.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A double-sided pneumatic chuck includes a base, a main body mounted on the top of the base, a drive gear driven by a computer on the top of the main body, a driven gear rotating inside the main body, and the driven gear and the drive gear meshing and transmitting power; a main chuck and a secondary chuck are respectively arranged on both sides of the main body, both of which rotate through the driven gear, and the middle part of the main body is hollow.

[0007] In addition, a preferred structure is that a gearbox is fixedly provided on the top of the main body, and the drive gear is adapted to rotate inside the gearbox.

[0008] In addition, a preferred structure is that a motor mounting base is fixedly provided on the outside of the gearbox, and the drive shaft of the motor mounting base is connected to the drive gear.

[0009] In addition, a preferred structure is that one side of the driven gear is connected to the auxiliary chuck, and a connecting column is fixedly provided on the other side. A chuck mounting seat is fixedly provided on the connecting column, and the chuck mounting seat is connected to the main chuck in a transmission connection.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-5 A double-sided pneumatic chuck includes a base 1, a main body 11 mounted on top of the base 1, a drive gear 121 driven by a computer on the top of the main body 11, and a driven gear 111 rotatably mounted inside the main body 11, with the driven gear 111 meshing with the drive gear 121 for transmission. A main chuck 2 and a secondary chuck 3 are respectively arranged on both sides of the main body 11, both rotating via the driven gear 111, and the center of the main body 11 is hollow.

[0021] The main body 11 has a gearbox 12 fixedly mounted on its top, and a drive gear 121 is adapted to rotate within the gearbox 12. A motor mounting base 13 is fixedly mounted on the outside of the gearbox 12, and the drive shaft of the motor mounting base 13 is connected to the drive gear 121. The user can install a motor on the motor mounting base 13, thereby driving the drive gear 121, which in turn drives the driven gear 111 and the chuck mounting base 221 to rotate, thus driving the main chuck 2 and the auxiliary chuck 3 to rotate synchronously.

[0022] In this design, one side of the driven gear 111 is connected to the auxiliary chuck 3, and the other side is fixedly equipped with a connecting post 22. A chuck mounting seat 221 is fixedly mounted on the connecting post 22 and is connected to the main chuck 2. It is worth noting that the connection structure between the chuck mounting seat 221 and the main chuck 2 is existing technology. Its purpose is to enable the main chuck 2 and the chuck mounting seat 221 to rotate synchronously. This is existing technology and is not related to the technical problem of improving clamping reliability that needs to be solved in this technical solution, so it will not be described in detail.

[0023] The main chuck 2 has multiple main grippers 21 movably mounted on it, and all of the main grippers 21 are pneumatically driven. The auxiliary chuck 3 has multiple auxiliary grippers 31 movably mounted on it, and all of the auxiliary grippers 31 are pneumatically driven. Both the main grippers 21 on the main chuck 2 and the auxiliary grippers 31 on the auxiliary chuck 3 are moved by cylinders to clamp the pipe. This is existing technology and not related to the technical problem of improving clamping reliability that this technical solution aims to solve; therefore, it will not be elaborated upon further.

[0024] In this embodiment, when the user needs to clamp and process the pipe, they only need to insert the pipe into the main body 11, so that the main chuck 2 and the auxiliary chuck 3 on both sides of the main body 11 are located at both ends of the pipe. Then, the main jaw 21 and the auxiliary jaw 31 are controlled by a cylinder to clamp the pipe. This achieves the positioning of the pipe. Furthermore, through the adaptation between the driving gear 121, the driven gear 111, and the chuck mounting base 221, the rotation of the main chuck 2 and the auxiliary chuck 3 can be controlled to achieve the rotation of the pipe during the clamping process, facilitating the user's processing of the pipe.

[0025] This device adopts an integrated chuck structure, with air passage structures on both sides of the main body 11. Independently controlled cylinders drive the main gripper 21 and the auxiliary gripper 31 to clamp the tubes respectively. This accommodates the dimensional errors of incoming materials processed by laser tube cutting machines and improves the adaptability of clamping tubes of different sizes.

[0026] In this device, the main chuck 2 and the auxiliary chuck 3 share a common drive structure. The chuck itself has mounting positions for the reducer, the drive gear 121, and the driven gear 111. The reducer and the drive gear 121 are installed inside the gearbox 12, and the driven gear 111 is installed inside the main body 11.

[0027] The main chuck 2 and the auxiliary chuck 3 are respectively equipped with main jaw 21 and auxiliary jaw 31. The inside of the chuck is through, and the workpiece can pass through. The main jaw 21 and auxiliary jaw 31 clamp the workpiece on both sides, which makes it more stable and avoids the phenomenon of the workpiece being thrown out, resulting in higher cutting accuracy.

[0028] Furthermore, both the main chuck 2 and the auxiliary chuck 3 employ floating cylinders. The rear end of the cylinder is fixed, while the front end floats, allowing for rotational freedom. It is connected to the synchronous gear ring, enabling the cylinder to swing during operation. This avoids the problem of air leakage caused by the cylinder piston rod being subjected to lateral force for a long time during operation.

[0029] Furthermore, both the main chuck 2 and the auxiliary chuck 3 adopt linear guides, which have high precision and large load capacity, effectively reducing the flaring phenomenon when clamping pipes and improving the clamping accuracy of the jaws. The overall clamping mechanism of one side chuck is arranged on the driven gear, which saves internal layout space, reduces the overall thickness, and reduces the chuck mass and rotational inertia.

[0030] In this utility model, a main chuck 2 and a secondary chuck 3 are respectively provided on both sides of the main body 11. The two ends of the pipe can be clamped separately by the main chuck 2 and the secondary chuck 3. This clamping method of the pipe is more stable and can avoid the phenomenon of pipe throwing, thereby improving the processing accuracy of the pipe.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
