[0023] The following is inspired by the ideal embodiment of the utility model. Through the following description, relevant personnel can make various changes and modifications without deviating from the technical idea of the utility model. The technical scope of the utility model is not limited to the content of the specification, and must be determined by the scope of the claims.

[0024] The utility model is further described with reference to the following drawings:

[0025] like Figures 1 to 4 As shown, a pneumatic chuck with a secondary clamping mechanism has a chuck body 100. The chuck body 100 is provided with a jaw mechanism 200, a drive mechanism 300, and a rotation mechanism 400. The rotation mechanism 400 can drive the chuck body 100 to rotate, and the drive mechanism 300 can drive the opening and closing of the jaw mechanism 200. The jaw mechanism 200 is provided with a secondary clamping mechanism 500. The secondary clamping mechanism 500 includes a secondary jaw 510, a clamping cylinder 520, and a reset device. The secondary jaw 510 can extend into the center hole of the chuck body 100 under the drive of the clamping cylinder 520. The secondary clamping mechanism 500 is correspondingly arranged on the jaw seats 210 of the two opposing jaw mechanisms 200.

[0026] The clamping cylinder 520 is a single-acting cylinder, and the reset device is the reset spring on the single-acting cylinder.

[0027] Alternatively, the reset device could be a reset spring mounted on the secondary chuck 510.

[0028] like Figure 5 As shown, the air path of the single-acting cylinder is controlled separately by a solenoid valve. The solenoid valve can control the single-acting cylinder to receive air, and its output shaft drives the auxiliary claw 510 to extend. When the single-acting cylinder releases air, the auxiliary claw 510 will retract under the control of the reset device.

[0029] The drive mechanism 300 is a drive cylinder 310 installed in the chuck body 100. The chuck body is provided with four drive cylinders 310. The four drive cylinders 310 are controlled by solenoid valves, and each solenoid valve controls the air path of two drive cylinders 310.

[0030] The drive mechanism 300 also includes a transmission component 320 disposed in the chuck body 100, and the drive cylinder 310 drives the chuck mechanism 200 to open and close through the transmission component 320.

[0031] The rotating mechanism 400 consists of a rotating gear 410 disposed on one side of the chuck body 100 and a rotating gear 420 disposed inside the chuck body 100.

[0032] The jaw seat 210 of the jaw mechanism 200 is mounted on the opening and closing slider 220, which can reciprocate along the opening and closing track 110 on the chuck body 100 under the drive of the drive mechanism 300.

[0033] like Figure 5 As shown, cylinders AB are drive cylinders 310 that control the clamping and loosening of the gripper mechanism 200, and C is clamping cylinder 520 on the auxiliary gripper 510.

[0034] Its control logic is: compressed gas is filtered by two joint, the inlet is controlled by the first solenoid valve, the jaw mechanism 200 clamps the workpiece, then the solenoid valve is powered off, the pressure is kept by the stop valve, the jaw mechanism 200 keeps clamping, the machine tool starts cutting, when cutting the last tail, the chuck stops, the C cylinder controlled by the third solenoid valve extends the pad to clamp the workpiece, the overcutting starts, after cutting, the second solenoid valve is controlled to control the inlet, the auxiliary jaw 510 is loosened, the roller jaw on the jaw mechanism 200 keeps clamping, the rear card pushes the roller jaw part to stop, the second solenoid valve is loosened, the jaw mechanism 200 opens, and the tail falls off (the chuck rotation solenoid valve must be powered off).

[0035] The preferred embodiments of the present application are described above, but the present application is not limited to the above, and can be variously changed and modified by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
