Problems solved by technology
Sometimes the traditional fixture cannot be clamped at all. Even if it can be clamped, the workpiece is easy to warp and deform, and even cause damage.
Sometimes the parts have been assembled on the aircraft, and the positioning and clamping cannot be performed, so manual drilling can only be used
Because there is no drilling guide, the phenomenon of drilling deviation often occurs

Embodiment Construction
[0009] The following structural drawings and embodiments describe the present invention in further detail.
[0010] see figure 1 , 2 As shown, this kind of drilling guide using vacuum clamping is characterized in that the guide includes a clamping body 3, a suction cup 5, a vacuum joint 1, a drill sleeve 6 and a positioning screw 7, and the clamping body 3 is in the shape of a circular plate The metal body has a round through hole 3a in the center of the clamp body 3, a drill sleeve 6 is installed in the round through hole 3a, and six threaded holes 3b are evenly opened on the circumference around the round through hole 3a, and the suction cup 5 made of rubber material It consists of a conical ring body 5b and a circular ring body 5a. The vacuum joint 1 is a hollow circular metal tube with a through hole 1b in the center. A small conical surface 1a is formed on the bottom end of the vacuum joint 1. The outer circle of the middle part of the vacuum joint 1 is formed with a Th...

The invention discloses a drilling guide tool achieving clamping through vacuum. The drilling guide tool is provided with three positioning screws 7 and three vacuum connectors 1. The three positioning screws 7 and the three vacuum connectors 1 are arranged in six threaded holes 3b in a clamp body 3 at intervals. When the drilling guide tool is in use, the heights of the three positioning screws 7 are respectively adjusted so that the axis of a drill bushing 6 of the clamp body 3 can coincide with the hole normal of a part to be drilled, the heights of the three vacuum connectors 1 are respectively adjusted so that a suction cup 5 can make contact with a part, and then vacuum suckers are installed on the small conical faces 1a of the vacuum connectors 1 to vacuumize the suction cup 5 so that the part and the clamp body 3 can be connected together; accordingly, drilling can be achieved through the drilling bushing 6. The drilling guide tool has the advantages of being capable of achieving clamping easily, convenient to adjust and particularly applicable to drilling for plane metal plate parts.
Description
technical field [0001] The invention relates to a drilling guide tool utilizing vacuum clamping, and belongs to the technical field of product structure. Background technique [0002] In the field of mechanical processing, especially when drilling holes in sheet metal parts similar to aircraft, the processing is very difficult because the sheet metal parts have thin thickness, curved surface, and are not easy to clamp. Sometimes the traditional fixture cannot be clamped at all, and even if it can be clamped, the workpiece is easily warped and deformed, or even damaged. Sometimes the parts have been assembled on the aircraft, and the positioning and clamping cannot be performed, so manual drilling can only be used. Because there is no drilling guide, the phenomenon of drilling deviation often occurs. Contents of the invention [0003] The present invention is designed to provide a drilling guide using vacuum clamping for the shortcomings of the above-mentioned existing de...
