The invention discloses a quick change cutter of a milling machine for solving the cutter change problem by changing a cutter sleeve clamping structure. The invention adopts the technical scheme that: the tail of a cutter sleeve (1) is provided with a threaded hole (2) and fixed on the main shaft of a milling machine (17) by using a tie bar (13); the middle part of the cutter sleeve (1) is provided with a wedge iron slotted hole (3) and a wedge iron slotted hole (5) from tail to head, and the head of the cutter sleeve (1) is provided with a dovetail notch (6) in which the tail is provided with a dovetail slot (4); the tail of a No.5 Morse taper shank (9) is a dovetail slot tail (7), the middle part is provided with a wedge iron slotted hole (10), and the head is provided with a cutter block (12) for forming a milling cutter (8); and the dovetail slot tail (7) of the No.5 Morse taper shank (9) is inserted into the dovetail slot (4) in the dovetail notch (6) of the cutter sleeve (1), the No.5 Morse taper shank (9) and the cutter sleeve (1) are positioned through the dovetail slot (4), and the No.5 Morse taper shank (9) and the cutter sleeve (1) are locked by using wedge irons (14) through the wedge iron slotted hole (5) and the wedge iron slotted hole (10). The quick change cutter has the advantages that: the cutter change time is 1 minute every time, and the saved cutter change time is 9 minutes, so the efficiency is improved, and the labor intensity is relieved.
Description
technical field [0001] The invention relates to a tool for machining, in particular to a quick-change tool for a milling machine. Background technique [0002] The original three milling cutters of the milling machine are clamped by tension ribs. During single-piece production, the operator needs to climb up and stand on the workbench every time a tool is changed, use a wrench to rotate the nut at the top of the equipment and use a tool to support the lower end milling cutter. Minutes, not suitable for production beats, and unable to combine the original three knives into one or two knives. Contents of the invention [0003] The invention discloses a quick-change tool for a milling machine, which solves the above problems by changing the clamping structure of the tool set. [0004] The technical solution adopted is to fix the tail of the tool holder (1) on the spindle of the milling machine (17); the No. 5 Morse taper shank (9) is inserted into the tool holder (1) and loc...
