Description

Technical Field

[0001] This utility model relates to the field of milling cutter positioning technology, and in particular to a high-efficiency positioning device for quick installation of milling cutters. Background Technology

[0002] In the field of machining, milling cutters, as core cutting tools, directly determine the quality stability of machined workpieces and the operational efficiency of production lines through the efficiency and accuracy of their installation and positioning. With the rapid development of high-end manufacturing industries such as aerospace and precision molds, increasingly stringent requirements have been placed on the speed, positioning accuracy, and repeatability of milling cutter installation. Traditional milling cutter installation and positioning methods have gradually revealed many shortcomings and are no longer suitable for the needs of modern high-efficiency production.

[0003] Chinese patent CN223588392U discloses a positioning device for milling cutter installation. The device controls the movement of the clamping block by rotating the rotating block, thereby achieving the clamping effect of the milling cutter. The spring setting ensures a tight connection between the milling cutter and the clamping block. The device has a simple structure and is easy to operate, but the clamping block only has two clamping points, which makes it difficult to stably clamp a circular milling cutter. After clamping, the milling cutter will still rotate on its own body. Moreover, the use of spring support can easily cause the position of the milling cutter to move back and forth. Therefore, a high-efficiency positioning device for quick installation of milling cutters is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency positioning device for quick installation of milling cutters.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A high-efficiency positioning device for quick installation of milling cutters includes a device body, a milling cutter body inserted into one side of the device body, a pusher connected to one end of the milling cutter body, a plurality of positioning holes and slots on the device body, positioning beads movably connected in the positioning holes and slots, a stop ring movably connected to the outside of the positioning beads, a rear stop ring connected to one side of the stop ring, and a limit threaded sleeve connected to the other end of the stop ring.

[0006] Preferably, a plurality of positioning grooves are arranged in a ring on the outer surface of the tail end of the milling cutter body, and positioning holes are arranged in a ring on the device body. The positioning holes correspond to the positioning grooves and are opened through the device body. The positioning holes are movably connected between the positioning grooves and the positioning holes.

[0007] Preferably, a insertion slot is provided on one side of the device body, the tail end of the milling cutter body is connected to the insertion slot, an inner groove is provided on the rear side of the insertion slot, the pusher is in the shape of an "I", a second spring is connected between the pusher and the insertion slot, and a third spring is connected between the pusher and the inner groove.

[0008] Preferably, the device body has multiple inner cavity grooves at its tail end, each inner cavity groove is movably connected to a push rod, a first spring is connected between the inner end of the push rod and the inner cavity groove, and the rear abutment ring is installed between the outer ends of the push rod.

[0009] Preferably, a second external thread is provided on the outer surface of the device body, the tail end of the abutment collar is threaded to the outside of the second external thread, the abutment collar is movably connected to the outside of the device body, and the inner surface of the abutment collar contacts the positioning bead.

[0010] Preferably, two limiting rings are also installed on the outer surface of the device body, and a limiting threaded sleeve is movably connected between the limiting rings. A first external thread is opened on the outer surface of the front end of the abutting sleeve, and the limiting threaded sleeve is threadedly connected to the first external thread.

[0011] The beneficial effects of this utility model are: This solution uses a pusher to continuously push the milling cutter body outward, facilitating its disassembly and removing any improperly installed milling cutters. This prevents improper installation during machining. The rear abutment ring and the limiting threaded sleeve position the abutment ring, preventing it from shifting and ensuring the positioning bead is securely attached to the milling cutter body.

[0012] This solution reduces the difficulty of stably clamping the milling cutter due to the limited number of clamping points during the clamping process, reduces the possibility of the milling cutter still rotating after clamping, improves the efficiency of the device for easy installation, and makes the position of the milling cutter more stable after clamping, and the parts are less likely to loosen. It also improves the device's detection effect on whether the milling cutter is installed in place, and can distinguish whether the milling cutter is installed in place by the positional relationship of the parts.
