Embodiment Construction

[0053] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0054] Such as Figure 1-3 As shown, a cutting machine for saving tailings includes a frame 101, a first guide rail 102, a front chuck 104 and a rear chuck 103, the top surface of the frame 101 is provided with a first guide rail 102, and the The first guide rail 102 is provided with a rear chuck 103, and the rear chuck 103 can reciprocate along the direction of the first guide rail 102. The frame 101 at the end of the first guide rail 102 is provided with a front chuck 104. The chuck 104 and the rear chuck 103 are independently driven respectively and have the same rotating speed. The centers of the front chuck 104 and the rear chuck 103 are on the same axis, and the front chuck 104 is provided with Extending to the through hole inside the front chuck 104 , the rear chuck 103 can extend into the inside of the through hole of the front chuck 104 . The front chuck 10...

Abstract

The invention provides a double-insurance pneumatic clamping chuck. The double-insurance pneumatic clamping chuck comprises a connecting disc, a chuck outer sleeve, a chuck inner sleeve, a separationdisc, a mounting disc, a clamping device, a guide device, a conversion device and a driving device, wherein one end of the chuck outer sleeve is provided with a connecting plate, the other end of thechuck outer sleeve is provided with the mounting disc, the chuck inner sleeve coaxially arranged with the chuck outer sleeve is further arranged between the connecting disc and the mounting disc, theguide device is arranged on the mounting disc, the clamping device is arranged on one side, outside the guide device, of the guide device, the conversion device is arranged on one side inside the guide device, the driving device is arranged between the conversion device and the connecting disc, the separation disc is arranged between the conversion device and the driving device, the conversion device is used for converting axial rotation of the conversion device into radial movement of the clamping device, and the driving device comprises a first driving device and a second driving device. Thetwo driving devices are arranged, so that double driving in one clamping direction can be realized, and normal operation of the equipment when one driving device breaks down is avoided.

Description

technical field [0001] The invention belongs to the technical field of pneumatic clamps, and in particular relates to a double-safety pneumatic clamping chuck. Background technique [0002] The chuck is a mechanical device used to clamp the workpiece on the machine tool. It uses the radial movement of the movable jaws evenly distributed on the chuck body to clamp and position the workpiece. It is a clamping device. [0003] Pneumatic chuck is a kind of chuck, which can automatically center and clamp the workpiece. The space of the chuck is limited, so the general pneumatic chuck uses a cylinder to drive a pair of opposite jaws to move synchronously, and there are only two small cylinders in a chuck. A pneumatic chuck with two jaws driven by one cylinder has the following problems: [0004] 1. Due to the unsteady movement of a single cylinder, the expansion and contraction of the claws is not stable enough; [0005] 2. Unsafe operation: Because one cylinder works independe...
