A new type of spring-type fixture for blade drilling

Abstract

The present invention discloses a novel spring type fixture for blade boring. The novel spring type fixture for blade boring comprises a fixture body (1). A clamping part (2) is disposed at the right end of the fixture body (1); a slide way (3), an expansion spring (4) and a support platform (5) are fixed on the left end face of the fixture body (1) in sequence from top to bottom; the expansion spring (4) is disposed perpendicular to the left end face of the fixture body (1); a push plate (6) is disposed at the other end of the expansion spring (4); and a slider (8) extends out of the fixture body (1) and is mounted on the guide rail (3). The fixture also comprises a controller that is connected to a horizontal air cylinder (7). The novel spring type fixture for blade boring has the advantages of compact structure, achieved fast missile blade clamping, improved boring efficiency, reduced labor intensity of a worker, and achieved fast product extraction.

Description

technical field [0001] The invention relates to the technical field of drilling holes on missile blades, in particular to a novel spring-type fixture for drilling holes in blades. Background technique [0002] The missile blades are used to change the direction of the missiles. The missile blades are fixed on the missile shell through tenons. The missile blades are drilled with a number of blind holes distributed along the circumferential direction. These blind holes are used to install sensors, such as figure 2 The above is a schematic diagram of the structure of the missile blade, wherein the missile blade is composed of the blade body and the tenon connected to the blade body. The existing processing method is: firstly install the tenon of the missile blade on the three-jaw chuck to complete the drill floor For tool setting, when the three-jaw chuck rotates at a certain angle, stop the rotation, and then use the drill floor to drill holes on the main body of the blade. In...

AI Technical Summary

Problems solved by technology

Although this processing method can realize drilling on the blade, the tenon is always clamped on the three-jaw chuck, and the three-jaw chuck is easy to pinch the tenon, which affects product quality

In addition, the tooling and blanking of the blade need to be tightened or loosened by the three-jaw chuck, which is very cumbersome to operate, increases the labor intensity of the workers, and reduces the drilling efficiency

Moreover, each tooling blade needs to be aligned with the drill bit, which further increases the workload and reduces the production efficiency.
