Description

Technical Field

[0001] The utility model relates to the technical field of milling tool processing, in particular to a milling tool positioning fixture. Background Art

[0002] Milling cutter is a cutting tool used in metal processing. It is mainly used for milling operations on machine tools such as milling machines and machining centers. Milling is a process of cutting or removing material from a workpiece by rotating a tool. It is usually used to manufacture parts, molds and other workpieces with complex shapes.

[0003] For example, a positioning fixture for surface grinding PCBN tools (Announcement No. CN216707133U) consists of left and right baffles and a support member mounted between them. The left baffle has a raised latch on one side, while the right baffle has a recessed slot. The left and right sides of the support member are equipped with the same recessed slots and raised latches as the left and right baffles. This fixture simplifies blade assembly, allowing for flexible selection of support members based on the number of blades to be ground. It also provides sufficient support for the blade, ensuring grinding accuracy. Multiple blades can be loaded simultaneously, resulting in high efficiency.

[0004] Based on the search of the above patents and combined with the equipment in the prior art, it was found that the above equipment still relies on manual adjustment and positioning when used, lacks automation, has low efficiency in clamping the cutter particles, and cannot adapt to the modern manufacturing industry's demand for efficient and precise processing. In addition, the support parts located between the left and right baffles lack a limiting structure. As the number of support parts increases, the stability of the cutter particles clamped between the support parts becomes worse during processing. Therefore, we need to propose a milling tool positioning fixture. Utility Model Content

The outer walls of the two groups of threaded rods 71 ​​are threadedly connected with three groups of convex sliders 72. Each group of movable baffles 4 is fixedly mounted on the top of the two oppositely arranged groups of convex sliders 72. A driven bevel gear 73 is fixedly sleeved on the outer wall of one end of the threaded rod 71. A driving member 74 is engaged on the opposite side of the two groups of driven bevel gears 73, which is convenient for driving the two groups of threaded rods 71 ​​to rotate through the driving member 74. The rotation of the two groups of threaded rods 71 ​​drives the three groups of convex sliders 72 threadedly connected on their surfaces to move, so that the convex sliders 72 oppositely arranged on the outer walls of the two groups of threaded rods 71 ​​move synchronously, driving the movable baffle 4 on their top to move.

[0025] The driving member 74 includes a dual-axis motor 741, which is fixedly installed on the inner top of the mounting groove 6 through a bracket.
