Description

Technical Field

[0001] The utility model belongs to the technical field of milling cutters, and more specifically, particularly relates to an assembled coating milling cutter. Background Art

[0002] A milling cutter is a rotary tool with one or more teeth used for milling. Each tooth cuts off the excess of the workpiece intermittently in sequence during operation. Milling cutters are mainly used to process planes, steps, grooves, forming surfaces and cut off workpieces on milling machines.

[0003] For example, a Chinese patent with publication number CN219924674U discloses an assembled coated milling cutter, including a connector, a connecting sleeve installed on the top of the connector, and a fixing assembly is provided on the connector; the fixing assembly includes an installation cavity, a screw, a clamping block, a nut and a gasket, and three groups of installation cavities are provided inside the connector, and the interior of the installation cavity is threadedly connected with a screw, and one end of the screw is rotatably connected with a clamping block. The utility model provides a fixing assembly, and the tool handle is inserted into the interior of the connector, passes through the connector and extends to the interior of the connecting sleeve. The card groove of the magnetic head at the top of the tool handle attracts the magnetic card block at the top of the inner wall of the connecting sleeve, and the tool body is connected to the connecting sleeve. By turning the screw, the screw drives the clamping block to move and clamp on the outside of the tool handle, and the tool body is fixedly connected to the connector and the connecting sleeve. The coating increases the hardness and oxidation temperature of the tool body, prolongs its service life, and the assembled connection installation reduces the risk of breakage of the milling cutter during use.

[0004] The technical solution recorded in this proposal is to rotate the screws in opposite directions, and the screws drive the clamping blocks to move closer to each other inside the connecting head, and the clamping blocks are clamped on the outside of the tool handle. This patent sets up three groups of installation cavities and uses screws to drive the clamping blocks to fix the tool handle. When fixing milling cutters of different diameters, it is necessary to rotate three screws at the same time to accurately fix the milling cutter handle on the central axis of the connecting head. If the axis of the tool handle is not on the same horizontal line as the axis of the connecting head, when the connecting head rotates, the milling cutter moves eccentrically, which will affect the processing accuracy of the workpiece.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and an assembled coated milling cutter is provided to achieve a purpose with greater practical value. Utility Model Content

[0033] The specific usage and function of this embodiment are as follows:

[0034] When using this product, first check whether the connection of the product is tight. After ensuring that it is intact, place the product in the designated position, insert one end of the milling cutter body 200 through the extrusion seat 1004 into the interior of the claw seat 1006, and then the user rotates the turntable 1003. A gear ring 1010 is installed inside the turntable 1003. The gear ring 1010 is engaged with the gear 1009 sleeved on the bottom end of the sleeve 1008, so that the sleeve 1008 can be rotated. The top of the screw 1007 threadedly connected to the internal thread of the sleeve 1008 is connected to the bottom end of the extrusion seat 1004, and the extrusion seat 1004 is slidably connected to the connecting seat 1002. Then, when the sleeve 1008 rotates, the screw 1007 can be used to drive the extrusion seat 10 04 is lifted and lowered, the extrusion groove 1005 opened in the extrusion seat 1004 is against the outer side of the upper end of the claw seat 1006, and the mountain end of the claw seat 1006 is truncated cone-shaped, and then as the extrusion seat 1004 is pressed down, the extrusion groove 1005 continuously presses the upper end of the claw seat 1006 to gather inward, thereby clamping and fixing the shank of the milling cutter body 200. Since the claw seat 1006 and the axis of the connecting rod 1001 and the connecting seat 1002 are maintained on the same horizontal line, therefore, when the upper end of the claw seat 1006 is synchronously gathered inward, the axis of the milling cutter body 200 and the axis of the claw seat 1006 are on the same horizontal line. Therefore, when the connecting rod 1001 rotates, the milling cutter body 200 will not rotate eccentrically.
