Description

Technical Field

[0001] This invention relates to the field of processing equipment technology, and in particular to a rotating device with a braking mechanism, a swivel head assembly, and a processing center. Background Technology

[0002] In existing rotary functional components such as rotary tables and milling heads, the braking structure is an extremely important component. The most mainstream braking structure currently uses a pneumatic or hydraulic brake piston to abut against the rotating body to brake the rotating shaft.

[0003] For example, please refer to the instruction manual appendix. Figure 1 Patent publication number CN 103358139 A discloses a CNC rotary table braking mechanism, including a brake cylinder body 1 and a drive shaft 2. The front end of the drive shaft is installed in the brake cylinder body, and a brake pad 4 is installed on the front end of the drive shaft through a bushing 3. A piston 5 is installed in the brake cylinder body, and an air inlet 6 is provided on the brake cylinder body. A positioning pin 7 is provided on the brake cylinder body. The brake pad and the piston are installed opposite to each other. Compressed air enters through the air inlet and pushes the piston to move, thereby pressing the brake pad and realizing the braking function.

[0004] However, in the aforementioned patent, when the piston 5 abuts against the brake pad, the piston 5 contacts the side of the brake pad facing the piston, resulting in a longer braking time for the piston 5 and a poorer braking effect.

[0005] Therefore, improving the braking efficiency of rotary functional components is an urgent problem to be solved. Summary of the Invention

It is to be understood that the scale shown in the accompanying drawings is not the actual scale of the present invention, and is for illustrative purposes only, and is not a drawing based on the original dimensions.

[0040] Please refer to Figure 2 and 3 The present invention provides a rotating device with a braking mechanism, comprising a fixed component 100 and a rotating component 200, wherein the rotating component 200 is capable of rotating relative to the fixed component 100.

[0041] In this embodiment, a rotating device with a braking mechanism is applied to a swivel head, which is a component used in a machining center to drive the spindle rotation.

[0042] Please refer to Figure 3 The fixed component 100 has a rotating shaft cavity 101, and the rotating component 200 is disposed in the rotating shaft cavity 101. The fixed component 100 has a rotating shaft cavity 101 along the axial direction L for mounting the rotating component 200. In this embodiment, the fixed component 100 can be a mounting base, and the rotating component 200 is rotatably mounted in the fixed component 100 through a bearing 600.

[0043] Please refer to Figure 3 A stator 410 and a rotor 420 are provided in the rotating shaft cavity 101. The rotor 420 is disposed in the stator 410 and is coaxial. The rotating component 200 includes a rotating shaft 210. The rotor 420 is fixedly connected to the rotating shaft 210 and is coaxial. It can be understood that the rotor 420 drives the rotating shaft 210 to rotate relative to the fixed component.

[0044] Please refer to Figure 2 and 3 The rotating device with a braking mechanism also includes a braking mechanism 300, which is disposed between the fixed component 100 and the rotating component 200 and is used to stop the rotating component 200 relative to the fixed component 100.

[0045] Please refer to Figure 4 The braking mechanism 300 includes a brake element 310 and a brake mating element 320. One of the brake element 310 and the brake mating element 320 is disposed on the fixed component 100, and the other is disposed on the rotating component 200. The brake element 310 and the brake mating element 320 engage in a braking cooperation. In this embodiment, the brake element 310 is fixedly mounted on the fixed component 100, and the brake mating element 320 is fixedly mounted on the rotating component 200. In some other embodiments, the brake element 310 is fixedly mounted on the rotating component 200, and the brake mating element 320 is fixedly mounted on the fixed component 100.

[0046] The fixing component 100 includes a mounting plate 110 with a shaft hole 111, the mounting plate 110 being disposed at one end of the rotating shaft cavity 101 along the axial direction L; the brake component 310 is fixedly mounted on the mounting plate 110; the rotating shaft 210 is rotatably disposed within the shaft hole 111; the brake mating component 320 is located at one end of the rotating shaft 210, and the axial brake mating part 321 and the radial brake mating part 322 are respectively located at different axial positions L of the rotating shaft 210. By providing the mounting plate 110, the brake component 310 can be installed more conveniently.

[0047] Please refer to Figure 3 and 4 The brake component 310 has a radial braking portion 311 that can move radially in the rotating component 200 and an axial braking portion 312 that can move axially in the rotating component 200. The brake mating component 320 includes an axial braking mating portion 321 and a radial braking mating portion 322. The brake component 310 has a braking state and a released braking state. When the brake component 310 is in the braking state, the radial braking portion 311 and the radial braking mating portion 322 abut against each other radially, and the axial braking portion 312 and the axial braking mating portion 321 abut against each other axially. In this embodiment, the radial braking portion 311 is located on the inner circumferential surface of the brake component 310, and the axial braking portion 312 is located on one end face of the brake component 310, thereby increasing the contact area between the brake component 310 and the brake mating component 320 and improving the braking efficiency of the brake mechanism 300. When the brake component 310 is in the released braking state, there is a gap between the radial brake part 311 and the radial brake mating part 322 in the radial direction, and between the axial brake part 312 and the axial brake mating part 321 in the axial direction.

[0048] Please refer to Figure 3 and 4 The brake component 310 is annular and includes a brake ring body 313. The radial brake portion 311 is located at the inner ring of the brake ring body 313, and the axial brake portion 312 is located at one end face of the brake ring body 313. The brake component 310 has a hollow portion 314 at the middle of the axial direction L of the rotating component 200. The brake component 310 is sleeved on the outer periphery of the radial brake mating portion 322. The radial brake mating portion 322 is located on the inner ring side of the brake ring body 313, and the axial brake mating portion 321 is located on one side of the brake ring body 313 along the axial direction L. The ring end face faces the axial brake mating portion 321. In this embodiment, the radial braking part 311 is sleeved radially J onto the outer periphery of the radial braking mating part 322, so that the radial braking mating part 322 is housed within the hollow part 314. It can be understood that when the brake member 310 is in the braking state, the inner periphery of the brake member 310 abuts against the outer periphery of the radial braking mating part 322, achieving braking through friction. The axial braking part 312 is arranged adjacent to the axial braking mating part 321 along the axial direction L of the rotating component 200. It can be understood that when the brake member 310 is in the braking state, one end face of the brake member 310 abuts against the end face of the axial braking mating part 321 along the axial direction L of the rotating component 200, achieving braking through friction.

[0049] Please refer to Figure 4The brake ring body 313 is a flexible ring body, and the flexible ring body has a first ring cavity 3131 and a second ring cavity 3132 that are interconnected. The cavity of the first ring cavity 3131 extends in the radial direction J, and the cavity of the second ring cavity 3132 extends in the axial direction L. The first ring cavity 3131 and the second ring cavity 3132 are located at different radii on the same axis, and the second ring cavity 3132 is located on the side where the inner ring portion of the brake ring body 313 is located. The maximum setting length of the first ring cavity 3131 in the radial direction J is greater than its maximum setting width in the axial direction L, and the maximum setting width of the second ring cavity 3132 in the axial direction L is greater than its maximum setting length in the radial direction J. The first ring cavity 3131 and the second ring cavity 3132 are approximately T-shaped. The first annular cavity 3131 and the second annular cavity 3132 receive external substances, causing the axial braking part 312 and the radial braking part 311 to move towards the axial braking mating part 321 and the radial braking mating part 322 along the axial direction L and the radial direction J, respectively. Alternatively, the first annular cavity 3131 and the second annular cavity 3132 discharge external substances, causing the axial braking part 312 and the radial braking part 311 to have gaps with the axial braking mating part 321 and the radial braking mating part 322 along the axial direction L and the radial direction J, respectively. And / or the brake member 310 is provided with heat insulation layers 315 on both ends along the axial direction L. In this embodiment, the brake member 310 is provided with heat insulation layers 315 on both ends along the axial direction L.

[0050] The brake mating component 320 includes a first brake disc 323 and a second brake disc 324 fixedly mounted on the rotating shaft 210. The radius of the first brake disc 323 is larger than the radius of the second brake disc 324. The disc surface of the first brake disc 323 faces the end face of the ring, and the circumferential surface of the second brake disc 324 faces the inner ring surface of the brake ring body 313. The axial brake mating part 321 is located on the disc surface of the first brake disc 323, and the radial brake mating part 322 is located on the circumferential surface of the second brake disc 324. By setting the first brake disc 323 and the second brake disc 324 to be separate from each other, it is convenient to install the first brake disc 323 and the second brake disc 324 onto the rotating shaft 210. In addition, when one of the first brake disc 323 and the second brake disc 324 is worn to the point of replacement, the first brake disc 323 or the second brake disc 324 can be replaced separately without replacing them together, thus improving the flexibility of replacing the first brake disc 323 and the second brake disc 324.

[0051] Please refer to Figure 3 and 4Because the brake component 310 is close to the stator 410 and rotor 420, the heat generated by the stator 410 and rotor 420 during operation will be transferred to the brake component 310. This will cause the brake component 310 to heat up and deform. In order to insulate the brake component 310 from the heat generated by the stator 410 and rotor 420 during operation, heat insulation layers 315 are provided on both ends of the brake component 310 along the axial direction L. The heat insulation layer 315 can be a metal coating, such as chromium, nickel, or tungsten. By providing the heat insulation layer 315, the brake component 310 can be prevented from absorbing the heat generated by the stator 410 and rotor 420, avoiding deformation of the brake component 310 due to heat rise, thereby preventing accidental braking.

[0052] In this embodiment, the brake element 310 can be a clamp. By providing a second annular cavity 3132 extending axially along L, the thickness of the inner circumference of the brake element 310 can be reduced, so that when the brake element 310 is in the braking state, the inner circumference of the brake element 310 can deform and abut against the radial brake mating part 322. By providing a first annular cavity 3131 extending radially along J, the thickness of the material in the middle circumference of the brake element 310 can be reduced, so that when the brake element 310 is in the braking state, one end face of the brake element 310 can deform and abut against the axial brake mating part 321.

[0053] Please refer to Figure 4 To ensure the brake element 310 is stably mounted on the fixed component 100 and to facilitate faster engagement of the brake element 310 with the axial brake mating part 321 along the axial direction L during braking, the brake element 310 is disposed on the fixed component 100. The fixed component 100 has a mounting step 112. The end face of the brake element 310 facing away from the axial brake mating part 321 is connected to the side end face 1121 of the mounting step 112. The outer peripheral surface of the brake element 310 facing away from the radial brake mating part 322 is connected to the inner peripheral wall 1122 of the mounting step 112. Specifically, the projected area of ​​the mounting step 112 along the axial direction L is smaller than the projected area of ​​the brake element 310 along the axial direction L. The outer peripheral portion of the brake element 310 is connected to the side end face 1121 of the mounting step 112 along the axial direction L. At least the inner peripheral portion of the brake element 310 extends radially J from the inner ring of the mounting step 112. This maximizes the contact area between the other end face of the brake component 310 away from the axial brake mating part 321 and the side end face 1121 of the mounting step 112, thereby improving the stability of the connection between the brake component 310 and the fixed part 100.

[0054] Please refer to Figure 4To increase the contact area between the axial brake engagement portion 321 and the brake element 310, and to facilitate the mounting of the axial brake engagement portion 321 onto the rotating component 200, the projected area of ​​the axial brake engagement portion 321 along the axial direction L is larger than the projected area of ​​the brake element 310 along the axial direction L. The outer periphery of the axial brake engagement portion 321 is approximately flush with the outer periphery of the brake element 310 along the axial direction L. The inner periphery of the axial brake engagement portion 321 extends radially J from the inner periphery of the brake element 310, and there is a gap between the inner periphery of the axial brake engagement portion 321 and the radial brake engagement portion 322 along the axial direction L. This allows the axial brake engagement portion 321 to abut against the entire end face of the brake element 310 when the brake element 310 moves along the axial direction L towards the axial brake engagement portion 321, increasing the contact area between the brake element 310 and the axial brake engagement portion 321, thereby improving braking efficiency.

[0055] The fixed component 100 is also provided with a conveying seat 700 that communicates with the brake mechanism 300. The conveying seat 700 is used to provide external substances to the brake mechanism 300. In this embodiment, the external substances are gas.

[0056] The aforementioned rotating device with a braking mechanism includes a braking mechanism 300, which comprises a brake element 310 and a brake mating element 320. The brake element 310 and the brake mating element 320 engage in a braking relationship. One of the brake element 310 and the brake mating element 320 is disposed on the fixed component 100, and the other is disposed on the rotating component 200. The brake element 310 has a radial braking portion 311 that is movable in the radial direction of the rotating component 200 and an axial braking portion 312 that is movable in the rotational axis of the rotating component 200. The brake mating element 320 includes an axial braking mating portion. When the brake member 310 is in a braking state, the radial brake part 311 and the radial brake mating part 322 abut against each other radially, and the axial brake part 312 and the axial brake mating part 321 abut against each other axially. This allows the radial brake part 311 to contact the radial brake mating part 322 and the axial brake part 312 to contact the axial brake mating part 321 when the brake member 310 is braking, thereby increasing the contact area between the brake member 310 and the brake mating part 320, reducing braking time, and improving braking effect.

[0057] When it is necessary to stop the rotating component 200 relative to the fixed component 100, gas is supplied to the brake component 310 through the delivery seat 700. After receiving the gas, the brake component 310 expands radially J toward the radial brake mating part 322 and abuts and rubs against the outer periphery of the radial brake mating part 322. At the same time, the axial brake part 312 expands toward the axial brake mating part 321 in the direction close to the axial direction L and abuts and rubs against one end face of the axial brake mating part 321 until the rotating component 200 stops relative to the fixed component 100. When it is necessary for the rotating component 200 to engage in a braking state relative to the fixed component 100, the gas is retracted from the brake component 310 via the delivery seat 700. After the brake component 310 loses the gas, the radial brake part 311 retracts in the radial direction J away from the radial brake mating part 322 and has a gap with the outer periphery of the radial brake mating part 322. At the same time, the axial brake part 312 retracts in the axial direction L away from the axial brake mating part 321 and has a gap with one end face of the axial brake mating part 321. The rotating component 200 is driven to rotate relative to the fixed component 100 via the built-in drive mechanism 400.

[0058] The present invention also provides a swing head assembly, including a swing head and the aforementioned rotating device with a braking mechanism, wherein the swing head rotates about an axis relative to the fixed component 100 via a rotating component 200, and the swing head includes a main shaft 800 connected to the rotating component 200, and the rotating component 200 drives the main shaft 800 to swing.

[0059] To save installation space for the oscillating head, the oscillating head also includes a conveying channel 500. The fixing component 100 includes a mounting frame 120, which can be U-shaped, so that the main shaft can be set in the U-shaped mounting frame 120. Both the left and right sides of the main shaft are rotatably connected to the U-shaped mounting frame 120, thereby improving the stability of the main shaft rotating around the mounting frame 120.

[0060] To enhance the versatility of the conveying channel 500, it is positioned between the mounting frame 120 and the braking mechanism 300. The conveying channel 500 is used at least to transport external liquids or gases through the mounting frame 120 along the outer periphery of the rotating component 200 to the braking mechanism 300. It also supplies power liquids or gases to the spindle cutting cylinder. This allows for the provision of power liquids or gases to both the braking mechanism 300 and the spindle cutting cylinder through a single conveying channel 500. Compared to the traditional two-channel approach, this saves on the number of channels required. Furthermore, by installing diversion valves, the connection and disconnection of power liquids or gases flowing to the braking mechanism 300 and the spindle cutting cylinder can be controlled separately, thus enabling independent control of both the braking mechanism 300 and the spindle cutting cylinder.

[0061] In some other embodiments, the conveying channel 500 may be disposed between the rotating component 200 and the braking mechanism 300. The conveying channel 500 is at least used to convey external liquid or gas through the rotating component 200 along the inner periphery of the rotating component 200 axial direction to the braking mechanism 300. The conveying channel 500 is also used to convey power liquid or gas to the spindle tool cylinder, thereby making reasonable use of the space of the rotating component 200 and improving the space utilization rate of the oscillating head.

[0062] The present invention also provides a machining center, including the aforementioned rotating device with a braking mechanism, or a machining center including the aforementioned swivel head assembly. In this embodiment, the machining center is a horizontal machining center, which includes a column and a sliding plate disposed on the column, and the swivel head assembly is mounted on the sliding plate.

[0063] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention is also intended to include these modifications and variations.

[0064] The above-listed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
