Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, specifically to a multi-angle rotating device for milling a hand-drip kettle. Background Technology

[0002] The multi-angle rotating device for milling pour-over kettles is a precision machining equipment. The core of the rotating device lies in its ability to achieve multi-angle rotation. Through a high-precision angle control mechanism and positioning device, it ensures that the parts can rotate at the specified angles during the machining process. This multi-angle rotating device can not only be used for the machining of golf club heads, but also for the precision machining of pour-over kettles, since pour-over kettles also have parts that require specific angle designs (such as the angle of the spout). During the machining process, the rotation angle of the top can be adjusted to meet different design requirements.

[0003] Chinese Patent Publication No. (CN215747855U) discloses a milling machine fixture capable of clamping workpieces at multiple angles, including a base plate, an adjustment mechanism, and a housing; a stepper motor is mounted on one side of the housing; the stepper motor is connected to a forward thread rod and a reverse thread rod, a moving block is sleeved on the outer side of the reverse thread rod, a support rod is fixed to the top of the moving block, a clamping plate is provided on one side of the support rod, a fixed seat is fixed to both sides of the top of the base plate, and a rotating block is provided on one side of the fixed seat;

[0004] The gear meshing transmission in the aforementioned comparative documents relies solely on a servo motor for power. When the machine tool experiences a power outage, circuit failure, or requires emergency manual adjustment, the operator cannot directly drive the gear pair to rotate manually, resulting in the complete failure of the fixture angle adjustment function. For example, if a power outage occurs suddenly after the workpiece is clamped, and it is necessary to fine-tune the workpiece angle to avoid machining interference, due to the lack of a manual adjustment mechanism, one can only wait for the power to be restored or disassemble the fixture, which seriously affects the machining efficiency.

[0005] In view of this, the present invention solves the above-mentioned technical problems by proposing a multi-angle rotation device for milling a hand-drip kettle. Utility Model Content

[0006] To address the shortcomings of the aforementioned background technology, this utility model provides a technical solution for a multi-angle rotation device for milling a hand-drip kettle. By adjusting the block assembly, it achieves dual-mode switching of "motor drive + manual drive", solving the problem of inability to adjust the angle during power outages or malfunctions in the prior art. For example, in the event of a sudden power outage, it can switch to manual mode within 30 seconds to complete the angle fine adjustment, avoiding downtime losses due to waiting for power restoration. At the same time, the electric drive and manual drive are integrated into the sliding plate, and the mode switching can be achieved through a single sliding action.

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.

[0026] Please see Figure 1-4 As shown, a multi-angle rotating device for milling pour-over kettles includes a base plate 1;

[0027] Two connecting blocks 2 are symmetrically arranged on the top of the base plate 1. A rotating block 201 is rotatably connected to the inner cavity of each connecting block 2. A rotating plate 202 is fixedly connected to the top of the rotating block 201 by bolts.

[0028] One end of the rotating block 201 is fixedly connected to a worm gear 3, and the top of the base plate 1 is fixedly connected to two symmetrically arranged mounting blocks 301. The inner cavity of the mounting block 301 is rotatably connected to a worm 302, which meshes with the worm gear 3.

[0029] An adjustment assembly is slidably connected to the inner cavity of the base plate 1. The adjustment assembly includes a sliding plate 4, a manual drive structure, and an electric drive structure. The inner cavity of the sliding plate 4 is rotatably connected to the manual drive structure, and the top of the sliding plate 4 is fixed with the electric drive structure.

[0030] A locking structure is provided on one side of the base plate 1;

[0031] The manual drive structure includes a connecting shaft 5, a driven gear 501, a driving gear 502, and a rocker arm 503. The connecting shaft 5 is rotatably connected to the inner cavity of the sliding plate 4. One end of the worm gear 302 is fixed with the driven gear 501, and one end of the connecting shaft 5 is fixed with the driving gear 502. The diameter of the driving gear 502 is larger than that of the driven gear 501. The other end of the connecting shaft 5 is fixed with the rocker arm 503.

[0032] The electric drive structure includes a rotary motor 6, a connecting groove 601, and a connector 602. The rotary motor 6 is fixed to the top of the sliding plate 4. One end of the worm gear 302 has a hexagonal connecting groove 601. One end of the connector 602 is fixedly connected to the output end of the rotary motor 6, and the other end is snapped into the inner cavity of the connecting groove 601.

[0033] The locking structure includes a sliding groove 7, a limiting plate 701, a fixing plate 702, and a locking pin 704. The sliding groove 7 is opened on one side of the base plate 1. The limiting plate 701 is slidably connected to the inner cavity of the sliding groove 7. The fixing plate 702 is fixed to one side of the base plate 1 below the limiting plate 701. Both the limiting plate 701 and the fixing plate 702 have locking holes 703 on their tops. The limiting plate 701 has one locking hole 703 on its top, and the fixing plate 702 has two locking holes 703 on its top. The locking pin 704 is slidably connected to the inner cavity of the locking hole 703.

[0034] The inner cavity of the rotating plate 202 is connected to a bidirectional screw 8 via a bearing. Two moving blocks 801 are threadedly connected to the surface of the bidirectional screw 8, and a servo motor 802 is fixedly connected to one end.

[0035] Each movable block 801 has a permanent magnet 9 embedded inside, and the inner cavity is slidably connected to a clamping block 901. The clamping block 901 and the inner cavity of the movable block 801 are connected together by a positioning pin 902.

[0036] Electric drive mode under normal operating conditions

[0037] When the angle needs to be adjusted, the rotary motor 6 is started through the external control system. The connector 602 at its output end drives the worm 302 to rotate (the connector 602 is engaged with the hexagonal connecting groove 601 of the worm 302 to ensure rigid power transmission).

[0038] The worm gear 302 meshes with the worm wheel 3, driving the rotating block 201 and the rotating plate 202 to rotate, thereby realizing the electric adjustment of the workpiece angle.

[0039] Manual drive mode (power outage / debugging conditions)

[0040] When the machine tool loses power or requires manual fine-tuning, first pull out the locking pin 704, slide the limit plate 701, and let the sliding plate 4 slide freely in the inner cavity of the base plate 1.

[0041] Push the sliding plate 4 to move away from the worm 302 until the connector 602 of the rotary motor 6 separates from the connecting groove 601 of the worm 302. At this time, the driving gear 502 and the driven gear 501 in the manual drive structure automatically mesh (the diameter of the driving gear 502 is larger than that of the driven gear 501, forming a reduction ratio and reducing the operating force).

[0042] Rotating the rocker arm 503 drives the drive gear 502 to rotate via the connecting shaft 5, which in turn drives the worm gear 302 via the driven gear 501, thus enabling manual angle adjustment of the worm wheel 3 and the rotating plate 202 (the rotation angle of the rocker arm per revolution is amplified by the gear reduction ratio; for example, when the number of teeth of the drive gear 502 and the number of teeth of the driven gear 501 are 5:1, a 360° rotation of the rocker arm 506 corresponds to a 72° rotation of the worm gear 302).

[0043] Workpiece clamping and adaptive adjustment

[0044] The bidirectional screw 8 on the rotating plate 202 is driven by the servo motor 802, which drives the two moving blocks 801 to move towards or away from each other, so as to realize the rapid clamping / releasing of the workpiece.

[0045] The permanent magnet 9 inside the movable block 801 attracts the clamping block 901. Different specifications of clamping blocks (such as flat clamps and V-shaped clamps) can be replaced according to the shape of the workpiece. When replacing, simply pull out the positioning pin 902, remove the old clamping block 901 and insert the new clamping block 901. The permanent magnet 9 quickly positions the workpiece, and then the positioning pin 902 is inserted to fix it, thus improving the versatility of the fixture.
