Description

Technical Field

[0001] The utility model belongs to the technical field of countersunk milling cutters, and particularly relates to a woodworking countersunk milling cutter. Background Art

[0002] A woodworking milling machine is a common furniture processing device, mainly used for milling wood furniture. Due to the diversity of house types, some large furniture needs to be processed on-site.

[0003] For example, the Chinese patent with the publication number CN218138661 U discloses a new type of woodworking countersunk milling cutter, which includes a first connecting seat, a second connecting seat and a third connecting seat; the first connecting seat is located at the top, a limiting hole is provided in the middle of the first connecting seat, and a number of limiting columns are embedded in the first connecting seat, and threaded holes or threaded rods are provided at both ends of each limiting column; the second connecting seat is located in the middle of the first connecting seat and the second connecting seat, the middle of the second connecting seat is hollow, and a motor assembly is provided; a number of limiting grooves are also embedded in the second connecting seat, and the opening size of the limiting groove is larger than the diameter of the end of the limiting column; a number of milling cutter heads for connecting the motor assembly are evenly distributed on the third connecting seat. Thus, the utility model limits the movement direction of the countersunk milling cutter by setting components such as the first connecting seat and the limiting column, and further achieves the purpose of precise processing.

[0004] When the existing woodworking countersunk milling cutter is in use, since the distance between the upper and lower tool holders remains fixed, when performing milling operations on countersinks with different depths, it is necessary to frequently switch the milling cutter, and the operation is relatively cumbersome. In view of this, we propose a woodworking countersunk milling cutter. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a woodworking countersunk milling cutter to solve the problem of frequently switching milling cutters when performing milling operations on countersinks with different depths as proposed in the above background art.

[0006] In view of this, the utility model provides a woodworking countersunk milling cutter, which includes a tool shank. An adjusting frame is fixedly connected to the outer wall of the tool shank. A worm is arranged inside the adjusting frame. One end of the worm is fixedly connected to a knob. A worm gear is meshed with the meshing surface of the worm. A connecting shaft that is rotationally connected to the inside of the tool shank is fixedly connected to the outer wall of the worm gear. A rotating cylinder is fixedly connected to the bottom end of the connecting shaft. A working groove is formed on the outer wall of the rotating cylinder. A telescopic column penetrates through the inside of the rotating cylinder. A working column that is fitted with the working groove is fixedly connected to the outer wall of the telescopic column. A limiting ring that is slidably connected to the outer wall of the telescopic column is fixedly connected to the bottom end of the tool shank. A limiting groove that is fitted with the outer wall of the limiting ring is formed on the outer wall of the telescopic column. An upper tool holder is fixedly connected to the bottom end of the tool shank. An upper milling cutter is fixedly connected to the outer wall of the upper tool holder. A lower tool holder is fixedly connected to the bottom end of the telescopic column. A lower milling cutter is fixedly connected to the outer wall of the lower tool holder

[0007] In this technical solution, the rotation of the rotating cylinder drives the synchronous rotation of two sets of spiral working grooves, so that the rotation of the working grooves drives the telescopic column to slide along the inner wall of the tool handle through the working column. At the same time, the sliding of the telescopic column drives the limiting groove to slide along the outer wall of the limiting ring, thereby improving the stability of the sliding of the telescopic column. The sliding of the telescopic column drives the lower tool holder and the upper tool holder to move relative to each other for woodworking countersink milling operations at different depths.

[0008] In the above technical solution, further, the central axis of the connecting shaft coincides with the central axis of the tool handle

[0009] In this technical solution, it is beneficial for the rotation of the knob to drive the rotation of the connecting shaft through the meshing of the worm and the worm wheel. The rotation of the connecting shaft drives the rotation of the rotating cylinder, realizing stable movement of the rotating cylinder rotation for taking selfies.

[0010] In the above technical solution, further, the outer shape of the working groove is spiral

[0011] In this technical solution, by setting the spiral working groove, it is beneficial for the rotation of the working groove to drive the telescopic column to slide along the inner wall of the tool handle through the working column, realizing the sliding operation of the telescopic column.

[0012] In the above technical solution, further, there are two sets of working grooves, and the two sets of working grooves are centrosymmetric about the rotating cylinder

[0013] In this technical solution, the rotation of the rotating cylinder drives the synchronous rotation of two sets of spiral working grooves, so that the rotation of the working grooves drives the telescopic column to slide along the inner wall of the tool handle through the working column, realizing the stable sliding operation of the telescopic column.

[0014] In the above technical solution, further, there are three sets of limiting grooves, and the cross-section of the limiting groove is arc-shaped

[0015] In this technical solution, by setting three sets of limiting grooves with an arc-shaped cross-section, it is beneficial for the sliding of the telescopic column to drive the limiting groove to slide along the outer wall of the limiting ring, thereby improving the stability of the sliding of the telescopic column. At the same time, the rotation of the tool handle drives the lower milling cutter on the outer wall of the lower tool holder to rotate synchronously through the limiting ring and the limiting groove.

[0016] In the above technical solution, further, an arc-shaped positioning block that fits the outer wall of the limiting groove is fixedly connected to the outer wall of the limiting ring

[0017] In this technical solution, by setting the limiting ring and the limiting groove, it is beneficial to improve the stability of the connection of the telescopic column.

[0018] In the above technical solution, further, the telescopic column forms a telescopic structure with the limiting ring through the working groove and the working column.

[0019] In this technical solution, the working groove rotates to drive the telescopic column to slide along the inner wall of the tool handle through the working column. At the same time, the sliding of the telescopic column drives the limiting groove to slide along the outer wall of the limiting ring, thereby improving the stability of the sliding of the telescopic column. The sliding of the telescopic column drives the lower tool holder and the upper tool holder to move relative to each other for woodworking countersink milling operations at different depths.

[0020] The beneficial effects of the present utility model are as follows:

[0021] 1. For this woodworking countersink milling cutter, by setting the rotating cylinder, the rotation of the rotating cylinder drives the two groups of spiral working grooves to rotate synchronously, so that the rotation of the working groove drives the telescopic column to slide along the inner wall of the tool handle through the working column. At the same time, the sliding of the telescopic column drives the limiting groove to slide along the outer wall of the limiting ring, thereby improving the stability of the sliding of the telescopic column. The sliding of the telescopic column drives the lower tool holder and the upper tool holder to move relative to each other for woodworking countersink milling operations at different depths.

[0022] 2. For this woodworking countersink milling cutter, by setting the limiting ring and the limiting groove, it is beneficial for the telescopic column to drive the limiting groove to slide along the outer wall of the limiting ring during sliding, thereby improving the stability of the sliding of the telescopic column. At the same time, the rotation of the tool handle drives the lower milling cutter on the outer wall of the lower tool holder to rotate synchronously through the limiting ring and the limiting groove.
