Detailed Description

The technical solutions of the present invention (including the preferred ones) are described in further detail below by way of fig. 1 to 9 and enumerating some alternative embodiments of the present invention. It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without any inventive step, are within the scope of the present invention.

As shown in fig. 1 to 9, the machining center in this example is a B-axis horizontal machining center, which is provided with a feeding and discharging station i and a machining station ii,

an upright post 2 is spanned outside the protection of the B-axis horizontal machining center 1 and beside the feeding and discharging station I, a cylinder 3 is installed on the upright post 2, a fluid supply device 4 is arranged at the output end of the cylinder 3, and the fluid supply device 4 is conveyed into the protection of the B-axis horizontal machining center 1 through the cylinder 3; the fixture 5 is installed on a B-axis horizontal machining center rotary table 6 and is sent to an exchange tray 7 through a Z-axis of a B-axis horizontal machining center 1, the fixture 5 is arranged under a fluid supply device 4 under the action of the exchange tray 7, the fluid supply device 4 is matched with a fluid receiving device 8 through the expansion and contraction of an air cylinder 3 to achieve the fluid supply effect, at the moment, the fixture 5 can achieve the functions of air detection, clamping, auxiliary supporting and the like, all oil pressure equipment on the fixture 5 plays a pressure maintaining effect through an energy accumulator 9, the fluid supply device 4 is separated from the fluid receiving device 8, and the fixture 5 goes to the B-axis machining center 1 to complete a series of machining contents.

The clamp 5 can reciprocate between the feeding station I and the discharging station II through a Z-axis of the machining center and the exchange tray 7; fluid enters and exits the clamp 5 through the fluid supply device 4 and the fluid receiving device 8 to enable the clamp 5 to clamp and loosen the workpiece;
