Description

Technical Field

[0001] This invention relates to a fixture, specifically an integrated machining fixture for multi-tube, multi-side hole milling machines. Background Technology

[0002] A milling machine is a machine tool that uses a milling cutter to machine various surfaces of a workpiece.

The first and second positioning parts on the first side plate 3 and the second side plate 4 are adjusted to the appropriate hole positions according to the machining angle. The product 2 is clamped on the fixing block 5 and fixed with the mounting bolt 54. The fixing block 5 containing the product is clamped between the positioning parts and locking parts on the first side plate 3 and the second side plate 4. Finally, the hole to be machined is sent to the machining position through the X and Y axis transmission guides of the milling machine. The hole on the product is machined by the milling machine spindle. When machining holes in other directions, simply pull up one "fixed pin or positioning pin 44" and rotate it to another "fixed pin or positioning pin 44" to insert into the tube. By rotating different main directions, side holes in different directions can be machined. When machining different tubes, the corresponding tube is moved to the fixed center 41 and the corresponding hole of the fixing block 5. This machining fixture can solve the problem of machining multiple pipes on a milling machine, each pipe having multiple side holes. It allows a single fixture on the milling machine to clamp and machine all the side holes simultaneously. Compared to traditional fixtures, it reduces the number of fixtures, lowers the cost of fixture manufacturing, and achieves process consolidation, reducing many machining steps and multiple clamping operations, thus greatly saving time in machining side holes and improving efficiency.

[0041] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
