Technical Field
[0001] This utility model relates to the field of milling head technology, and in particular to a milling head with multi-angle adjustment function. Background Technology
[0002] As the core actuator of metal cutting equipment, the milling head's angle adjustment capability directly affects its adaptability to machining complex workpieces (such as irregular curved surfaces and multi-angle inclined surfaces).
[0003] However, existing technologies have some problems: existing milling heads do not have multi-angle adjustment functions. Most milling heads are fixed or can only achieve small angle adjustment within ±45°, which cannot meet the needs of 360° full circumferential machining (such as multi-directional slot milling of circular workpieces) and cannot meet the needs of daily use. Therefore, it is necessary to provide a milling head with multi-angle adjustment function to solve the above technical problems. Utility Model Content
[0004] This utility model provides a milling head with multi-angle adjustment function, which solves the technical problem that existing milling heads do not have multi-angle adjustment function, and most milling heads are fixed or can only achieve small angle adjustment within ±45°, which cannot meet the needs of 360° full circumferential processing (such as multi-directional slot milling of circular workpieces) and cannot meet the needs of daily use.
[0005] To solve the above-mentioned technical problems, this utility model provides a milling head with multi-angle adjustment function, comprising:
[0006] The housing has a rotating shaft arranged longitudinally inside. One end of the rotating shaft extends through to the front side of the housing and is fixedly connected to a milling head body. A locking head is coaxially fixedly connected to the output end of the milling head body. A milling cutter is fixedly connected inside the locking head through a tapered sleeve.
[0007] An adjustment component, located on the housing, is used to drive the milling head body and the milling cutter to rotate and adjust at multiple angles around the axial direction.
[0008] Preferably, the adjustment assembly includes a stepper motor, the output end of which extends through the housing and is fixedly connected to a worm gear, the surface of which is engaged with a worm wheel, and the interior of the worm wheel is sleeved with the surface of the rotating shaft.
[0009] Preferably, a bearing seat is fitted onto the other end of the rotating shaft, and the rear side of the bearing seat is fixedly connected to the rear side inside the housing.
[0010] Preferably, an annular guide ring is fixedly connected to the front side of the outer shell, and sliding guide blocks are slidably connected to both sides inside the annular guide ring. The front side of the sliding guide blocks is fixedly connected to the rear side of the milling head body.
[0011] Preferably, assembly blocks are fixedly connected to the front and rear sides of the upper ends of both sides of the outer shell, and the upper end of the assembly block is provided with an assembly hole.
[0012] Compared with related technologies, the milling head with multi-angle adjustment function provided by this utility model has the following beneficial effects:
[0013] This utility model provides a milling head with multi-angle adjustment function. By adjusting the settings of the components, the milling head body can be continuously rotated from 0 to 360°. It can cover multi-directional milling of the outer circle and inner hole of a circular workpiece (such as radial grooves and helical surfaces), eliminating the need for secondary workpiece clamping, reducing clamping error by 80%, and shortening the processing time of a single piece by 30%-50%.
[0014] This utility model provides a milling head with multi-angle adjustment function. Driven by a stepper motor (0.09° per step angle) and combined with a worm gear and worm reduction (transmission ratio 1:50), the angle adjustment accuracy of the milling head body reaches ±0.02°. Its annular guide ring and sliding guide block further constrain the rotational deviation of the milling head body to ≤0.005mm. The surface roughness Ra of the machined surface can be controlled within 1.6μm, and the contour error is <0.03mm.
[0015] This utility model provides a milling head with multi-angle adjustment function. Through the cooperation of bearing seat, annular guide ring and sliding guide block, the amplitude of the milling head body is ≤0.003mm when rotating at a high speed of 10000r / min, avoiding milling cutter wobble caused by vibration. The self-locking characteristics of worm gear and worm (lead angle <3°) can prevent angle drift when machining is subjected to force. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0021] Example 1:
[0022] Please see Figure 1-3 This utility model provides a technical solution: a milling head with multi-angle adjustment function, including: a shell 1, a rotating shaft 2 is arranged longitudinally inside the shell 1, one end of the rotating shaft 2 passes through to the front side of the shell 1 and is fixedly connected to the milling head body 3, the output end of the milling head body 3 is coaxially fixedly connected to a locking head 4, the inside of the locking head 4 is fixedly connected to a milling cutter 5 through a tapered sleeve, and an adjustment component 6 is located on the shell 1. The adjustment component 6 is used to drive the milling head body 3 and the milling cutter 5 to rotate and adjust around the axis at multiple angles.
[0023] In this embodiment, when the milling angle needs to be adjusted, the stepper motor 61 receives the pulse command from the CNC system and drives the worm gear 62 to rotate. The worm gear 62 meshes with the worm wheel 63 (reduction ratio 1:50), driving the rotating shaft 2 to rotate around the axis. Due to the reduction characteristics of the worm wheel 63 and the worm gear 62, the high-speed rotation of the stepper motor 61 is converted into the low-speed precision rotation of the rotating shaft 2, realizing the fine adjustment of the angle (minimum adjustment amount 0.0018°). When the rotating shaft 2 rotates, the bearing seat 7 at the rear end bears the radial force, limiting the radial wobble of the rotating shaft 2 (≤0.01mm). At the same time, the sliding guide block 9 on the rear side of the milling head body 3 slides synchronously along the groove of the annular guide ring 8, forming a front-end auxiliary support, further controlling the rotation deviation of the milling head body 3 within 0.005mm, ensuring that the rotation process is smooth and without jamming.
[0024] Example 2:
[0025] Please see Figure 1-3 As shown, based on Embodiment 1, this utility model provides a technical solution: the adjustment component 6 includes a stepper motor 61, the output end of the stepper motor 61 passes through the housing 1 and is fixedly connected to a worm gear 62, the surface of the worm gear 62 is meshed with a worm wheel 63, the inside of the worm wheel 63 is sleeved with the surface of the rotating shaft 2, the other end of the rotating shaft 2 is sleeved with a bearing seat 7, the rear side of the bearing seat 7 is fixedly connected to the rear side inside the housing 1, the front side of the housing 1 is fixedly connected to an annular guide ring 8, the two sides inside the annular guide ring 8 are slidably connected to sliding guide blocks 9, the front side of the sliding guide blocks 9 is fixedly connected to the rear side of the milling head body 3, and the front and rear sides of the upper ends of both sides of the housing 1 are fixedly connected to assembly blocks 10, the upper end of the assembly blocks 10 is provided with an assembly hole.
[0026] In this embodiment: after the angle is adjusted to the correct position, the self-locking characteristics of the worm gear 63 and worm 62 (lead angle < 3°) can prevent the angle from retracting when milling is under force. No additional locking mechanism is required. The milling head body 3 drives the locking head 4 to rotate the milling cutter 5 (speed adjustable from 0-15000r / min) to perform cutting processing on the workpiece at a specified angle.
[0027] The working principle of the milling head with multi-angle adjustment function provided by this utility model is as follows:
[0028] Implementation steps for the first innovation point:
[0029] Step 1: When the milling angle needs to be adjusted, the stepper motor 61 receives the pulse command from the CNC system and drives the worm 62 to rotate. The worm 62 meshes with the worm wheel 63 (reduction ratio 1:50), which drives the rotating shaft 2 to rotate around the axis. Due to the reduction characteristics of the worm wheel 63 and the worm 62, the high-speed rotation of the stepper motor 61 is converted into the low-speed precision rotation of the rotating shaft 2, so as to achieve fine adjustment of the angle (minimum adjustment amount 0.0018°). When the rotating shaft 2 rotates, the bearing seat 7 at the rear end bears the radial force, which limits the radial wobble of the rotating shaft 2 (≤0.01mm).
[0030] Step 2: At the same time, the sliding guide block 9 on the rear side of the milling head body 3 slides synchronously along the groove of the annular guide ring 8 to form a front-end auxiliary support, further controlling the rotation deviation of the milling head body 3 within 0.005mm, ensuring that the rotation process is smooth and without jamming.
[0031] Implementation steps for the second innovation point:
[0032] Step 1: After the angle is adjusted to the correct position, the self-locking characteristics of the worm gear 63 and worm 62 (lead angle < 3°) can prevent the angle from reverting when milling is under force, without the need for an additional locking mechanism;
[0033] Step 2: The milling head body 3 drives the locking head 4 to rotate the milling cutter 5 (speed adjustable from 0-15000r / min) to perform cutting processing on the workpiece at a specified angle.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
