Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The large-scale double-sided frame type numerical control machining vacuum fixture comprises two vacuum tool main body parts with flat plate structures, and a connecting lock catch is arranged at the middle position of the two vacuum tool main body parts. The connecting lock catch is mainly used for connecting the parts of the two tools, and two parts can be simultaneously processed after the connecting lock catch is installed. The two end surfaces of the vacuum tool main body part are respectively provided with a part positioning hole and a waist-shaped positioning hole, wherein the waist-shaped positioning holes are positioned at the connecting end accessories of the two butt-joint vacuum tool main body parts, and the part positioning holes are positioned at the other end of the vacuum tool main body part and are used for preventing parts from being misplaced when the parts are installed. In addition, the main body part of the vacuum tooling is also provided with a round pin hole and a diamond pin hole for positioning and installation. The vacuum tool main body parts are provided with reverse side vacuum pipeline grooves for vacuum pipeline installation, wherein the reverse side vacuum pipeline grooves on the vacuum tool main body parts are communicated in a cross mode, and the end parts of the vacuum tool main body parts are provided with vacuum connecting holes for vacuumizing. In addition, the edge of the outer side of the main body of the vacuum tool is provided with a 5.5mm adhesive tape sealing groove for sealing and installing an adhesive tape, so that the phenomenon that the cutter is scrapped due to the fact that the part is not tightly adsorbed due to air leakage during vacuumizing is avoided.
Please refer to fig. 2, which is a schematic structural diagram of the connecting lock of the main body of the tooling. And the two ends of the connecting lock catch are respectively provided with a diamond positioning hole and a circular positioning hole which are respectively used for being connected with the two ends of the two tool-shaped body parts.
Please refer to fig. 3, which is a schematic diagram of a vacuum connector pipeline, wherein the vacuum connector pipeline is disposed in a vacuum pipeline groove on the reverse side of a main body of a vacuum tool and connected to a vacuum connector hole, and a valve for controlling the communication of the pipeline is disposed on the pipeline.
Referring to fig. 4, the outermost periphery of the main body of the vacuum tool is provided with an elastic reverse bolt, which is designed in a reverse manner and sleeved with a spring for fixing the blank and the tool, so that the blank and the tool are prevented from being misplaced and clamped in the clamping process.
According to the utility model, when the large double-sided frame type numerical control machining vacuum clamp is used for carrying out part timing machining, a plurality of pairs of round convex positioning pins and diamond convex positioning pins are respectively machined at two ends and the front side of a blank, wherein the round convex and the diamond convex at the joint are matched with the round positioning holes and the diamond positioning holes on the connecting lock catch in the picture 2.
And after the front surface of the part is completely machined, reversely buckling the machined surface of the part on a vacuum fixture, and performing positioning work by using a positioning hole and a positioning waist-shaped hole on the fixture and a round convex positioning pin and a diamond convex positioning pin on the machined blank. And through evacuation for vacuum frock main part becomes the sucking disc, produces the negative pressure, adsorbs the fixed part. Simultaneously for guaranteeing the leakproofness of anchor clamps, use the higher joint strip of degree of adhesion (see 5.5mm adhesive tape seal groove in figure 1) on the sucking disc, the base angle of part need be avoided to 5.5mm seal groove, is equivalent with the part appearance, and the frock bottom surface uses evacuation joint and hose to connect simultaneously, and for reducing the incomplete problem of absorption that leads to because of the sealing problem, vacuum joint evenly distributed is in the frock bottom surface (400mm regional one vacuum joint).
