Detailed Implementation

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] This utility model discloses a simple tooling for improving the positional accuracy of a broaching machine, comprising, from top to bottom, an upper broaching machine mounting plate 3, an upper broaching machine sliding copper plate 2, and an upper broaching machine download plate 1. The upper broaching machine mounting plate 3, the upper broaching machine sliding copper plate 2, and the upper broaching machine download plate 1 are moved and limited in the middle by a flat key pin, and a stainless steel sleeve 6 is provided on the outside of the middle connecting part; the top of the upper broaching machine mounting plate 3 is provided with three limiting blocks 4.

[0018] The upper loading plate 3 of this utility model is equipped with a pneumatic top mounting block 5. The upper loading plate 3 has two one-way valve holes. One-way ball valves are installed in the one-way valve holes. The upper loading plate 3 is equipped with a waterproof sleeve. Chip removal grooves are formed on the surface of the sliding copper plate 2 of the upper loading plate. The upper loading plate 3, the sliding copper plate 2, and the lower loading plate 1 of the upper loading plate are mounted on the loading plate.

[0019] This utility model features three carrier plates: the upper and lower plates are made of 45 steel, the middle plate is made of copper sheet, and the three top limiting blocks are also made of 45 steel. A flat key pin is used in the middle for movement and positioning. A stainless steel sleeve is used for the connecting part to prevent water damage and debris from disrupting the surface. Two one-way valve holes are provided on the upper carrier plate for one-way ball valves, used for routine refueling and maintenance.

[0020] The moving pins between the upper and lower carrier plates are arranged laterally and longitudinally to ensure smooth forward, backward, left, and right movement of the carrier plates. Specifically, the lower carrier plate 1 of the upper broaching machine is made of GCr15 material, heat-treated to HRC48-52, and has both ends ground flat; the sliding copper plate 2 of the upper broaching machine is a copper block with chip removal grooves and an oil-textured finish; the upper carrier plate 3 of the upper broaching machine is also made of GCr15 material, heat-treated to HRC48-52, and has both ends ground flat. Waterproof spacers are installed at the inner hole and outer circumference of the upper carrier plate 3 to prevent surface contamination during the broaching process.

[0021] This invention utilizes a 6×16×3 keyway milled on the surface of the carrier plate and the copper block (using a 6×15.8×6 keyway). Three limiting blocks are installed on the upper carrier plate to ensure the workpiece is fixed in the center. The machining position is maintained by moving the carrier plate. This invention has a simple structure and is easy to use. The combined use of three carrier plates and three limiting blocks ensures the workpiece is fixed in the center, and the machining position is maintained by moving the carrier plate, thus improving the positional accuracy of broaching machine machining.
