Embodiment Construction

[0026] The present invention will be further explained below in conjunction with the drawings.

[0027] Such as figure 1 with figure 2 A composite tool head suitable for machining energetic materials is shown. It includes a spindle 1. An outer tool seat 11 and an inner tool seat 2 are installed on both sides of the spindle 1 respectively. The outer tool seat 11 and the inner tool seat 2 pass through bolts. The connection is installed on both sides of the spindle 1. When the outer tool holder 11 and the inner tool holder 2 are connected, the inner hole between them is aligned with the marking line on the end face of the spindle 1 to ensure the accuracy of axis rotation. The outer tool holder 11 and the inner tool The L-shaped positioning surface of the seat 2 at the seat mouth (ie the edge position of the lower end of the outer tool holder 11 and the inner tool holder 2) and the end surface of the spindle 1 can realize the axial positioning of the tool head. The lower end of the ...

Abstract

The invention discloses a composite tool head applicable to energetic material machining. The composite tool head comprises a main shaft, wherein an outer cutter seat and an inner cutter seat are respectively mounted on two sides of the main shaft; a milling cutter is mounted at the lower end of the main shaft; a cutter holder is mounted at the lower end of the outer cutter seat; a guiding groove is formed in the obverse side of the cutter holder; a positioning groove is formed in the reverse side of the cutter holder; the guiding groove and the positioning groove communicate with each other; a sliding stud is mounted in the guiding groove; a threaded column is arranged at one end of the sliding stud and outward extends out of the guiding groove; a square screw hole head is arranged at the other end of the sliding stud and inward extends into the positioning groove; a first tiny hole is formed in the threaded column; a turning cutter is arranged at the lower end of the cutter frame and mounted in the positioning groove; a vertical column is mounted at the lower end of the obverse side of the cutter holder; a second tiny hole is formed in the vertical column; a diamond wire is mounted between the first tiny hole and the second tiny hole; and the first tiny hole and the second tiny hole are coaxially arranged. By adoption of the composite tool head, the demand for working-procedure combined machining of small-batch, various-specification and multi-sized workpieces can be met, and integrated efficient machining of multi-variety and small-batch workpieces can be achieved.

Description

Technical field [0001] The invention relates to the technical field of mechanical processing of energetic materials, in particular to a composite tool head suitable for mechanical processing of energetic materials. Background technique [0002] High-energy explosive PBX (Polymer Bonded Explosives, polymer bonded explosives) is a kind of energetic material with excellent comprehensive performance. As the main explosive of strategic weapons and conventional advanced weapons warheads, it is widely used in land, sea, air and second artillery. Among various weapon systems, it is one of the core materials in weapon equipment systems. Due to its low stiffness and strength, high thermal expansion coefficient, and certain viscoelasticity, this material is a very special heterogeneous, macroscopic, homogeneous, and microscopically anisotropic composite material, and exhibits soft, The complex characteristics of stickiness, brittleness and elasticity affect the processing quality and safet...
