Description

Technical Field

[0001] This utility model relates to a ball end mill, specifically a ball end mill capable of precise positioning, and belongs to the field of ball end mill technology. Background Technology

[0002] Ball end mills are cutting tools with a ball-shaped cutting edge that are mounted on a milling machine for milling various curved surfaces and circular grooves. Ball end mills are also called R-cutters. Ball end mills can mill mold steel, cast iron, carbon steel, alloy steel, tool steel, and general iron materials. They belong to the category of end mills and can operate normally in high-temperature environments.

[0003] However, most existing ball end mills have various problems. For example, in a ball end mill disclosed in publication number CN115106583A for milling, although it adopts a double screw clamping method to provide sufficient clamping force for the insert, further improve clamping stability, prevent the insert from loosening, and increase the insert's service life, the current ball end mills often need to adjust their angle according to the actual situation during machining. However, most current ball end mills adjust their angle through an external support structure, and the external support structure can only be adjusted in one direction, such as the X-axis or Y-axis. In some scenarios that require precise positioning, the external support structure cannot meet the machining requirements, and additional connecting parts are required, which is cumbersome, time-consuming, and labor-intensive. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technologies are too simplistic. Specifically, the purpose of this utility model is to solve the aforementioned shortcomings of existing technologies by proposing a ball end mill capable of precise positioning.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A ball-end cutting tool capable of precise positioning includes a base, a support frame, a connecting rod, an adjusting seat, a fixing plate, a ball-end cutting tool, and an angle adjustment mechanism. The support frame is fixed on the base, the connecting rod is rotatably connected to one side of the support frame, the adjusting seat is rotatably connected to the connecting rod, the fixing plate is fixed inside the adjusting seat, the ball-end cutting tool is connected to one end of the fixing plate, and the angle adjustment mechanism is disposed on the support frame. The angle adjustment mechanism includes a connecting sleeve, a fixed seat, a limiting plate, and an adjusting rod. The connecting sleeve is rotatably connected to the side of the adjusting seat away from the fixed plate. The fixed seat is fixed to the connecting sleeve and has a crossbar inside. The limiting plate is fixed to one end of the adjusting rod and has an arc-shaped groove. The crossbar inside the fixed seat is slidably engaged in the arc-shaped groove. The adjusting rod is rotatably connected to the support frame.

[0006] As a further embodiment of this utility model: the angle adjustment mechanism further includes a linkage plate, a first driven rod, a sliding seat, and a second driven rod. The linkage plate is rotatably connected to the limiting plate and has slots at both ends. The first driven rod is disposed on the outer wall of the fixed seat and is slidably engaged in the slot at one end of the linkage plate. The sliding seat is slidably connected to the adjusting rod. The second driven rod is disposed on the sliding seat and is slidably engaged in the slot at the other end of the linkage plate.

[0007] As a further improvement of this utility model: the outer wall of the adjusting rod is fixed with a strip-shaped protrusion, the inner wall of the sliding seat is provided with a strip-shaped groove, and the strip-shaped protrusion is slidably engaged in the strip-shaped groove.

[0008] As a further embodiment of this utility model: the angle adjustment mechanism further includes a transmission rod, a chuck, and a slot. The transmission rod is slidably and rotatably connected to the support frame and is arranged in parallel with the adjustment rod. The chuck is coaxially fixed to one end of the transmission rod, and the slot is arranged on the adjustment rod. The chuck is rotatably engaged in the slot.

[0009] As a further improvement of this utility model, two linkage plates are symmetrically arranged on both sides of the limiting plate.

[0010] As a further embodiment of this utility model: both the first driven rod and the second driven rod are rotatably sleeved with rotating cylinders, and the rotating cylinders are rotatably engaged in the slots provided on the linkage plate.

[0011] The beneficial effects of this utility model are: In this invention, an angle adjustment mechanism is provided. The sliding seat causes the second driven rod to rotate, which in turn drives the first driven rod to move. This causes the fixed seat to slide on the limit plate. The rotation of the adjustment seat then adjusts the angle of the ball end cutter in the X-axis direction. Simultaneously, the rotation of the adjustment rod adjusts the force direction of the connecting sleeve, causing the adjustment seat to rotate on the docking rod. This allows for angle adjustment of the ball end cutter in the Y-axis direction, enabling simultaneous X and Y-axis angle adjustment. This allows for precise positioning of the ball end cutter, simplifies operation, and effectively improves machining accuracy. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0015] like Figures 1 to 4 As shown, a ball-end cutting tool capable of precise positioning includes a base 1, a support frame 2, a connecting rod 3, an adjusting seat 4, a fixing plate 5, a ball-end cutting tool 6, and an angle adjustment mechanism 7. The support frame 2 is fixed on the base 1, the connecting rod 3 is rotatably connected to one side of the support frame 2, the adjusting seat 4 is rotatably connected to the connecting rod 3, the fixing plate 5 is fixed inside the adjusting seat 4, the ball-end cutting tool 6 is connected to one end of the fixing plate 5, and the angle adjustment mechanism 7 is set on the support frame 2. The angle adjustment mechanism 7 includes a connecting sleeve 71, a fixed seat 72, a limiting plate 73, and an adjusting rod 74. The connecting sleeve 71 is rotatably connected to the side of the adjusting seat 4 away from the fixed plate 5. The fixed seat 72 is fixed to the connecting sleeve 71 and a crossbar is provided inside the fixed seat 72. The limiting plate 73 is fixed to one end of the adjusting rod 74 and an arc-shaped groove is provided on the limiting plate 73. The crossbar inside the fixed seat 72 is slidably engaged in the arc-shaped groove. The adjusting rod 74 is rotatably connected to the support frame 2. The angle adjustment mechanism 7 also includes a linkage plate 75, a first driven rod 76, a sliding seat 77, and a second driven rod 78. The linkage plate 75 is rotatably connected to the limiting plate 73, and slots are provided at both ends of the linkage plate 75. The first driven rod 76 is set on the outer wall of the fixed seat 72 and is slidably engaged in the slot at one end of the linkage plate 75. The sliding seat 77 is slidably connected to the adjusting rod 74. The second driven rod 78 is set on the sliding seat 77 and is slidably engaged in the slot at the other end of the linkage plate 75. The angle adjustment mechanism 7 also includes a transmission rod 79, a chuck 710, and a slot 711. The transmission rod 79 is slidably and rotatably connected to the support frame 2 and is arranged in parallel with the adjustment rod 74. The chuck 710 is coaxially fixed to one end of the transmission rod 79. The slot 711 is arranged on the adjustment rod 74, and the chuck 710 is rotatably engaged in the slot 711.

[0016] In this invention, by setting an angle adjustment mechanism 7, the sliding seat 77 causes the second driven rod 78 to push the linkage plate 75 to rotate, which in turn drives the first driven rod 76 to move together, thereby causing the fixed seat 72 to slide on the limiting plate 73. The rotation of the adjusting seat 4 causes the ball end cutter 6 to adjust its angle in the X-axis direction. At the same time, the rotation of the adjusting rod 74 can adjust the force direction of the connecting sleeve 71, thereby causing the adjusting seat 4 to rotate on the docking rod 3, thus realizing the angle adjustment of the ball end cutter 6 in the Y-axis direction. This allows the ball end cutter 6 to simultaneously achieve angle adjustment in both the X and Y axes, enabling precise positioning of the ball end cutter 6. The operation is simple and also effectively improves the machining accuracy. Example 2

[0017] like Figures 1 to 4 As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes: The outer wall of the adjusting rod 74 is fixed with a strip-shaped protrusion, and the inner wall of the sliding seat 77 is provided with a strip-shaped groove. The strip-shaped protrusion is slidably engaged in the strip-shaped groove. The strip-shaped protrusion limits the sliding seat 77 so that when the sliding seat 77 slides on the adjusting rod 74, it can also rotate synchronously with the adjusting rod 74.

[0018] Two linkage plates 75 are symmetrically arranged on both sides of the limiting plate 73, so that the fixing base 72 can be evenly stressed on both sides.

[0019] Both the first driven rod 76 and the second driven rod 78 are rotatably fitted with rotating cylinders, and the rotating cylinders are rotatably engaged in the slots provided on the linkage plate 75. The rotation of the rotating cylinders reduces the frictional resistance between the linkage plate 75 and the first driven rod 76 and the second driven rod 78.

[0020] Working principle: When using this ball end cutter, first push the transmission rod 79, which in turn drives the sliding seat 77 to slide on the adjusting rod 74 via the chuck 710. During the sliding, the second driven rod 78 pushes the linkage plate 75 to rotate, and the linkage plate 75 drives the first driven rod 76 to move together, which in turn drives the fixed seat 72 to slide on the limiting plate 73. Then, the rotation of the adjusting seat 4 drives the ball end cutter 6 to adjust its angle in the X-axis direction. At the same time, the rotation of the adjusting rod 74 adjusts the force direction of the connecting sleeve 71, which in turn drives the adjusting seat 4 to rotate on the docking rod 3, thereby realizing the angle adjustment of the ball end cutter 6 in the Y-axis direction.

[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
