Multi-purpose carbon fiber T-shaped milling cutter with angle-adjustable cutter head

Abstract

This utility model discloses a multi-purpose carbon fiber T-shaped milling cutter with an adjustable angle head, including a support frame, a drive component, and a milling mechanism. The support frame is fixed on an external machine tool, the drive component is rotatably connected inside the support frame and has a conical structure, and the milling mechanism is mounted on the support frame. The beneficial effects of this utility model are: by setting a conical drive component and an annular active ring, the active ring transfers the power of the drive component, driving the driven wheel to rotate, which in turn drives the connecting cylinder and the T-shaped milling cutter to rotate as a whole for milling operations. Simultaneously, the conical structure allows the active ring to slide along the conical surface of the drive component while the support seat rotates on the support frame to adjust the angle, synchronously adjusting the rotation speed of the T-shaped milling cutter. This achieves synchronous control of angle adjustment and speed linkage, simplifying the traditional step-by-step operation into a single-action adjustment. Furthermore, the active ring automatically matches the contact position of the conical surface as the angle changes, adjusting the speed in real time.

Description

Technical Field

[0001] This utility model relates to a T-slot milling cutter, specifically a multi-purpose carbon fiber T-slot milling cutter with an adjustable angle tip, belonging to the technical field of T-slot milling cutters. Background Technology

[0002] A T-slot cutter is a tool mounted on a milling machine for milling T-shaped grooves and side grooves on workpieces. Also called a T-slot end mill, semi-circular end mill, or keyway end mill, it can perfectly machine T-shaped grooves and side grooves, maintaining its cutting performance even at high temperatures.

[0003] However, most existing T-slots have various problems. For example, in the split carbon fiber T-slot with an anti-dislocation structure disclosed in announcement number CN222856824U, although the anti-dislocation component between the shank and the cutter head is set to extend the stability of the connection between the shank and the cutter head and effectively prevent dislocation during use, in this technical solution and most current T-slots, in the current field of carbon fiber composite material processing, the T-slot generally needs to adjust the tool angle according to the actual processing situation. When facing different processing angles, the required tool speed is also different. Therefore, current milling cutters need to adjust the speed of the drive device while adjusting the angle, which requires at least two steps. The operation is cumbersome and affects the processing efficiency. Traditional milling cutters need to repeatedly test to determine the speed-angle combination, which increases the processing preparation time. This current technical situation seriously restricts the demand for efficient processing of complex carbon fiber components. 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 multi-purpose carbon fiber T-type end mill with an adjustable angle cutter head.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-purpose carbon fiber T-type end mill with an adjustable angle cutting head includes a support frame, a drive component, and a milling mechanism. The support frame is fixed on an external machine tool, the drive component is rotatably connected inside the support frame and has a tapered structure, and the milling mechanism is mounted on the support frame.

[0007] The milling mechanism includes a support, a driven wheel, a driving ring, a docking cylinder, and a T-shaped milling cutter. The support has a semi-circular structure, and its two ends are rotatably connected to one side of the support frame. The driven wheel is rotatably connected to the support. The driving ring is engaged between the driving component and the driven wheel and rolls against them. The docking cylinder is coaxially fixed with the driven wheel and rotatably connected to the support. The fixed part of the T-shaped milling cutter is connected and locked inside the docking cylinder.

[0008] As a further embodiment of this utility model: the milling mechanism further includes a worm wheel and a worm, the worm wheel is coaxially fixed on the support base and the rotating connection end of the support frame, and the worm wheel is rotatably connected to the support frame, the worm is rotatably connected to the support frame and meshes with the worm wheel.

[0009] As a further embodiment of this utility model: the support frame is also rotatably connected to an abutment member, the abutment member and the driving member are arranged side by side, and both of them are conical in shape and their two ends are arranged in opposite directions. The active ring rolls and abuts between the abutment member and the driving member.

[0010] As a further embodiment of this utility model: a slot is provided through the support frame, and a slider is slidably engaged in the slot. The two ends of the abutment are rotatably connected to the two sliders respectively. A screw hole is provided between the support frame and the slot, and an adjusting screw is threaded in the screw hole. One end of the adjusting screw is rotatably connected to the slider.

[0013] The beneficial effects of this utility model are:

[0014] In this invention, a conical drive component and an annular active ring are used. The active ring transfers the power of the drive component and drives the driven wheel to rotate, which in turn drives the docking cylinder and the T-shaped milling cutter to rotate as a whole for milling operations.

[0020] 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

[0021] like Figures 1 to 4 As shown, a multi-purpose carbon fiber T-type milling cutter with adjustable angle head includes a support frame 1, a drive component 2 and a milling mechanism 3. The support frame 1 is fixed on an external machine tool, the drive component 2 is rotatably connected inside the support frame 1 and has a conical structure, and the milling mechanism 3 is mounted on the support frame 1.

[0022] The milling mechanism 3 includes a support 31, a driven wheel 32, a driving ring 33, a docking cylinder 34, and a T-shaped milling cutter 35. The support 31 has a semi-circular structure, and both ends of the support 31 are rotatably connected to one side of the support frame 1. The driven wheel 32 is rotatably connected to the support 31. The driving ring 33 is engaged between the driving member 2 and the driven wheel 32 and rolls against them. The docking cylinder 34 is coaxially fixed with the driven wheel 32 and rotatably connected to the support 31. The fixed part of the T-shaped milling cutter 35 is connected and locked inside the docking cylinder 34.

[0023] The milling mechanism 3 also includes a worm wheel 36 and a worm 37. The worm wheel 36 is coaxially fixed on the support 31 and the rotating connection end of the support frame 1, and the worm wheel 36 is rotatably connected to the support frame 1. The worm 37 is rotatably connected to the support frame 1 and meshes with the worm wheel 36.

[0024] In this invention, a conical drive component 2 and an annular active ring 33 are provided. The active ring 33 transfers the power of the drive component 2 and drives the driven wheel 32 to rotate, which in turn drives the docking cylinder 34 and the T-shaped milling cutter 35 to rotate as a whole for milling operations. At the same time, the conical structure allows the support seat 31 to rotate on the support frame 1 to adjust the angle, while the active ring 33 can slide along the conical surface of the drive component 2 and simultaneously adjust the rotation speed of the T-shaped milling cutter 35. This achieves synchronous control of angle adjustment and speed linkage, simplifying the traditional step-by-step operation into a single-action adjustment. Furthermore, the active ring 33 automatically matches the contact position of the conical surface as the angle changes and adjusts the speed in real time to ensure that the cutting parameters are always adapted to the anisotropic requirements of carbon fiber. Example 2

[0025] like Figures 1 to 4 As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0026] The support frame 1 is also rotatably connected to an abutment 4. The abutment 4 and the driving component 2 are arranged side by side, and both of them have a conical structure and are arranged in opposite directions at both ends. The active ring 33 rolls against the abutment 4 and the driving component 2. The stability of the active ring 33 is ensured by the cooperation between the abutment 4 and the driving component 2.

[0027] A slot is provided through the support frame 1, and a slider 5 is slidably engaged in the slot. The two ends of the abutment 4 are rotatably connected to the two sliders 5 respectively. A screw hole is provided between the support frame 1 and the slot. An adjusting screw 6 is threaded in the screw hole. One end of the adjusting screw 6 is rotatably connected to the slider 5. The position of the slider 5 on the support frame 1 is adjusted by adjusting the adjusting screw 6, so that the abutment 4 and the driving component 2 can be quickly adjusted.

[0028] The passive wheel 32 has an annular groove recessed in its peripheral wall. The active ring 33 is engaged in the annular groove. The groove limits the movement of the active ring 33, thereby improving its stability.

[0029] At least three passive wheels 32 are provided on the support 31, and are respectively located at the two ends of the support 31 and the support frame 1 that are rotatably connected, and at the center of the support 31. All passive wheels 32 abut against the active ring 33. By setting multiple passive wheels 32, the active ring 33 can be subjected to force at multiple points during linkage, further ensuring its stability.

[0030] Working principle: When using this T-slot milling cutter, first connect and lock the T-slot milling cutter 35 inside the docking cylinder 34. Then connect one end of the drive component 2 to the external drive device and drive the drive component 2 to rotate through the external drive device. At this time, the driving ring 33 is linked between the drive component 2 and the abutment component 4, and synchronously drives the driven wheel 32 to rotate. The driven wheel 32 drives the docking cylinder 34 and the T-slot milling cutter 35 to rotate as a whole to perform milling operations. When it is necessary to adjust the milling angle of the T-slot milling cutter 35, rotate the worm gear 37 to make the worm wheel 36 mesh and link. At this time, the support seat 31 deflects. At the same time, using the conical structure, the support seat 31 rotates on the support frame 1 to adjust the angle, while the driving ring 33 can slide along the conical surface of the drive component 2 and synchronously adjust the rotation speed of the T-slot milling cutter 35.
