[0001] The present invention relates to the technical field of linear motor braking, and in particular to a mounting structure of an eddy current brake plate of a linear motor. Background Art

[0002] In linear motors, there is a braking method that uses eddy currents to slow down the motor rotor. The specific structure includes symmetrically arranged mounting seats, with stator assemblies provided on both sides of the mounting seats, and a rotor assembly provided between the stator assemblies on both sides. The rotor assembly has a permanent magnet, and the rotor assembly moves between the stator assemblies on both sides. A brake plate is also provided on the mounting seat, and the brake plate is also symmetrically distributed with the moving trajectory of the rotor assembly as the symmetry axis. During braking, the permanent magnets on the moving rotor assembly act as a changing magnetic field, causing the brake plate to cut the magnetic flux lines and induce current, that is, generate eddy currents to form a braking force until the rotor assembly gradually stops moving.

DETAILED DESCRIPTION

[0019] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0021] In the description of the present invention, "a plurality" refers to more than two. The use of "first" or "second" is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of the indicated technical features, or implicitly indicating the order of the indicated technical features.

[0022] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0023] As described in the background art, and with reference to Figure 1 In the structure shown, the mounting base 400 is symmetrically arranged, and brake plates 100 are arranged on the opposite surfaces of the mounting base 400. The flat-plate mover assembly 500 is arranged in the middle of the brake plates 100 on both sides. In order to improve the reliability of eddy current braking, the brake plates 100 need to be firmly connected to the mounting base 400 and cannot be loose. The installation relationship between the brake plates 100 and the mounting base 400 is as follows: Figure 2 shown.

[0024] Reference Figure 3 As shown, the installation structure of the eddy current brake plate of a linear motor according to an embodiment of the present invention includes a brake plate 100 , a first connecting member 200 , a second connecting member 300 and a mounting seat 400 .

[0025] The first connecting member 200 is provided on the brake plate 100. The first connecting member 200 can be permanently fixed to the first connecting member 200. For example, the brake plate 100 and the first connecting member 200 can be independently processed and then welded to a designated position. The brake plate 100 and the first connecting member 200 can also be integrally formed, for example, by casting the brake plate 100 with the first connecting member 200 and then fine-machining it by milling. The first connecting member 200 can also be detachably connected to the brake plate 100.

[0026] The second connecting member 300 has a first movable portion 310 and a second movable portion 320 hinged to each other. The first movable portion 310 and the second movable portion 320 can rotate around the hinge axis to a locked position or an unlocked position. In the locked position, the second connecting member 300 is connected to the first connecting member 200.

[0027] In some embodiments, the first movable portion 310 and the second movable portion 320 are connected to the first connector 200 by clamping. Specifically, the first movable portion 310 and the second movable portion 320 rotate about the hinge axis and move in opposite directions to open, that is, the first movable portion 310 and the second movable portion 320 are in the unlocked position. Then, the portion of the first connector 200 used for connection is placed between the first movable portion 310 and the second movable portion 320. The first movable portion 310 and the second movable portion 320 are then rotated toward each other about the hinge axis to close, that is, the first movable portion 310 and the second movable portion 320 are in the locked position, completing the clamping of the first connector 200.

[0028] The mounting seat 400 is provided with an accommodating cavity 410 , and the second connecting member 300 is inserted into the accommodating cavity 410 . The accommodating cavity 410 can keep the second connecting member 300 in a locked position, and the brake plate 100 is fixed to the mounting seat 400 .

[0029] In an embodiment where the first movable portion 310 and the second movable portion 320 are connected to the first connector 200 by clamping, the first movable portion 310 and the second movable portion 320 are in a locked position, in a closed state. The second connector 300 in this state is inserted into the accommodating cavity 410. The accommodating cavity 410 restricts the second connector 300, preventing the first movable portion 310 and the second movable portion 320 from rotating open. That is, the accommodating cavity 410 can maintain the second connector 300 in the locked position. At this time, the first connector 200 is constantly clamped by the first movable portion 310 and the second movable portion 320. The brake plate 100 is fixed to the mounting base 400 through the cooperation of the first connector 200, the second connector 300, and the accommodating cavity 410.

[0030] Reference Figure 4 As shown, it can be understood that the end of the first connecting member 200 away from the brake plate 100 is provided with a clamping head 210, and the first movable part 310 and the second movable part 320 are both provided with a groove body. In the locked position, the first movable part 310 and the second movable part 320 are spliced ​​together, and the groove body surrounds a clamping groove 330, and the clamping head 210 is set in the clamping groove 330. It should be understood that in order to present the structure of the first movable part 310 and the second movable part 320 splicing together to form the clamping groove 330, Figure 4 The structure shown is when the first movable portion 310 and the second movable portion 320 are in the locked position, but at this time the clamping head 210 of the first connecting member 200 is not placed in the clamping slot 330 .

[0031] Specifically, in some embodiments, the first connector 200 may be a cylindrical rod, and the diameter of the clamping head 210 is larger than the diameter of the first connector 200. The first movable portion 310 and the second movable portion 320 are assembled to form a clamping slot 330. The diameter of the clamping slot 330 matches the diameter of the clamping head 210. When the clamping head 210 is placed in the clamping slot 330, the first connector 200 is restricted by the second connector 300, so that the first connector 200 cannot move in its own axial direction. It should be understood that when the second connector 300 is inserted into the accommodating cavity 410, the first connector 200 moves in its own axial direction along with the second connector 300 and is fixed in the accommodating cavity 410, thereby fixing the brake plate 100 to the mounting seat 400. When the first connector 200 cannot move in its own axial direction, the brake plate 100 cannot move away from the mounting seat 400.

[0032] Initially, the first movable portion 310 and the second movable portion 320 are in the unlocked position. At this point, the first movable portion 310 and the second movable portion 320 are open, and the slots have not yet been joined to form the slot 330. The clamping head 210 of the first connector 200 is placed in any slot, such as the slot of the first movable portion 310. The first movable portion 310 and the second movable portion 320 are then rotated toward each other. The slots of the second movable portion 320 and the first movable portion 310 are joined to form the slot 330, with the clamping head 210 positioned within the slot 330. At this point, the first connector 200 and the second connector 300 are coaxial, and the second connector 300 is inserted into the accommodating cavity 410. It should be understood that the axial lengths of the first connector 200 and the second connector 300 match the axial length of the accommodating cavity 410, so that after the second connector 300 is inserted into the accommodating cavity 410, the brake plate 100 fits snugly against the mounting seat 400.

[0033] Reference Figure 5 As shown, it can be understood that the accommodating cavity 410 has a first end and a second end, and the second connecting member 300 is inserted into the accommodating cavity 410 from the first end toward the second end. The accommodating cavity 410 is provided with a guide slope 411, and the guide slope 411 gradually shrinks from the first end toward the second end.

[0034] When the second connector 300 is inserted from the first end of the accommodating cavity 410, the first movable portion 310 and the second movable portion 320 are completely moved from a slightly open position to a locked position due to the contraction of the guide slope 411. The provision of the guide slope 411 facilitates the assembly of the second connector 300 with the accommodating cavity 410. The second connector 300 can be inserted into the accommodating cavity 410 even with rough positioning. The second connector 300 is guided by the guide slope 411 and moves toward the second end of the accommodating cavity 410 until the second connector 300 is fixed in the designed position in the accommodating cavity 410.

[0035] It can be understood that the mounting seat 400 is provided with a through accommodating cavity 410, and the end of the second connecting member 300 away from the brake plate 100 passes through the accommodating cavity 410, and the second connecting member 300 is provided with a fixing member 340, which is located at the passing end of the second connecting member 300, and the fixing member 340 abuts against the end face of the accommodating cavity 410.

[0036] After design and calculation, the lengths of the first connecting member 200 and the second connecting member 300 and the length of the accommodating cavity 410 can be adapted to each other, so that after one end of the second connecting member 300 passes through the accommodating cavity 410, it still has sufficient length for the fixing member 340 to connect, and after the fixing member 340 abuts against the end face of the accommodating cavity 410, the brake plate 100 also fits tightly against the mounting seat 400.

[0037] It can be understood that the second connecting member 300 also includes a third movable part 350, one end of the third movable part 350 is hinged to the end of the first movable part 310 and the end of the second movable part 320 respectively, the other end of the third movable part 350 passes through the accommodating cavity 410, and the fixing member 340 is arranged on the third movable part 350.

[0038] The third movable part 350 is introduced as a basis for setting up the fixing part 340. One end of the third movable part 350 passes through the accommodating cavity 410. The first movable part 310 and the second movable part 320 can be retained in the accommodating cavity 410, ensuring that the first movable part 310 and the second movable part 320 are fixed in a locked position by the accommodating cavity 410, keeping the first connecting part 200 and the second connecting part 300 reliably connected.

[0039] Reference Figure 6 and Figure 7 As shown, it can be understood that the third movable part 350 is provided with a connecting column 351 at one end away from the first movable part 310, and the fixing part 340 is a clamping strip 341. The clamping strip 341 is provided with a strip groove 342, and the strip groove 342 is arranged along the length direction of the clamping strip 341. The connecting column 351 is passed through the strip groove 342, and the connecting column 351 can move in the strip groove 342 so that the clamping strip 341 can switch between a fixed position and a non-fixed position. In the non-fixed position, the length direction of the clamping strip 341 is parallel to the axis of the third movable part 350. In the fixed position, the length direction of the clamping strip 341 intersects with the axis of the third movable part 350, and the clamping strip 341 abuts against the end face of the accommodating cavity 410.

[0040] First, move the clamping strip 341 so that the connecting column 351 and the clamping strip 341 can be relatively displaced, that is, the connecting column 351 moves along the strip groove 342, and adjust the position of the clamping strip 341 so that the connecting column 351 is at the end of the strip groove 342. At this time, the clamping strip 341 can rotate around the connecting column 351 so that the axis of the clamping strip 341 and the third movable part 350 are parallel to each other, that is, the clamping strip 341 is in a non-fixed position.

[0041] In some embodiments, after the clamping head 210 of the first connecting member 200 is placed in the clamping slot 330, the clamping strip 341 is adjusted to a non-fixed position, and the clamping strip 341 is first inserted into the accommodating cavity 410, and the second connecting member 300 and the first connecting member 200 are continued to be pushed until one end of the third movable part 350 passes through the accommodating cavity 410, that is, the connecting column 351 and the clamping strip 341 both pass through the accommodating cavity 410. Then adjust the position of the clamping strip 341 so that the connecting column 351 moves along the strip groove 342 to the middle of the strip groove 342. In this state, the axis of the clamping strip 341 intersects with the axis of the third movable part 350, that is, the clamping strip 341 is in a fixed position. After the axis of the clamping strip 341 intersects with the axis of the third movable part 350, the axial length of the clamping strip 341 is greater than the inner diameter of the accommodating cavity 410. The clamping strip 341 abuts against the end face of the accommodating cavity 410, preventing the second connecting member 300 from falling out of the accommodating cavity 410, thereby fixing the first connecting member 200 and the second connecting member 300.

[0042] Reference Figure 8 As shown, it can be understood that the third movable part 350 is equipped with a first elastic member 352, and the accommodating cavity 410 is provided with a first abutment platform 412. When the clamping strip 341 passes through the accommodating cavity 410 and is in a fixed position, the first elastic member 352 contacts the first abutment platform 412, and the first elastic member 352 is compressed along the axial direction of the accommodating cavity 410.

[0043] When the end of the third movable part 350 has not yet passed through the accommodating cavity 410, the first elastic member 352 first contacts the first abutment platform 412. At this time, the first elastic member 352 has not yet been compressed; the second connecting member 300 is continued to be pushed so that the end of the third movable part 350 passes through the accommodating cavity 410. In the process of pushing the second connecting member 300, the first elastic member 352 is blocked by the first abutment platform 412 and is compressed, and has elastic force. The end of the third movable part 350 passes through the accommodating cavity 410 and places the clamping strip 341 in a fixed position. The compressed first elastic member 352 tends to reset. The elastic force generated by the first elastic member 352 is applied to the third movable part 350, so that the third movable part 350 has a tendency to exit the accommodating cavity 410. Since the clamping strip 341 abuts the end face of the accommodating cavity 410, the third movable part 350 cannot exit the accommodating cavity 410. Under the action of the elastic force, the clamping strip 341 is more closely attached to the end face of the accommodating cavity 410. Under non-human conditions, the possibility of the clamping strip 341 changing from a fixed position to a non-fixed position is further reduced.

[0044] The first elastic member 352 can be a spring, which is mounted on the third movable portion 350. The diameter of the third movable portion 350 can be smaller than the diameter of the first movable portion 310 and the second movable portion 320 after being assembled. Therefore, the spring can abut against the assembled first movable portion 310 and the second movable portion 320. An annular first abutting platform 412 can be provided in the accommodating cavity 410, and the third movable portion 350 can pass through the center of the first abutting platform 412, so that the spring contacts the annular first abutting platform 412.

[0045] Reference Figure 9 As shown, it can be understood that the fixing member 340 is a protrusion 343, the protrusion 343 is arranged on the third movable part 350, the protrusion 343 protrudes radially along the third movable part 350, the accommodating cavity 410 is provided with a giveway groove 413, the giveway groove 413 extends axially along the accommodating cavity 410, the cross-sectional size of the position of the protrusion 343 is larger than the cross-sectional size of the accommodating cavity 410, and the protrusion 343 can move along the giveway groove 413 to pass through the accommodating cavity 410.

[0046] When the third movable portion 350 is inserted into the accommodating cavity 410, it is necessary to rotate the third movable portion 350 along its circumferential direction so that the protrusion 343 is aligned with the position of the clearance groove 413. After the protrusion 343 passes through the accommodating cavity 410, it is no longer restricted by the accommodating cavity 410 and can continue to rotate along the circumferential direction of the third movable portion 350, so that the protrusion 343 and the clearance groove 413 are misaligned. Because the cross-sectional dimensions of the protrusion 343 are larger than the cross-sectional dimensions of the accommodating cavity 410, when the protrusion 343 and the clearance groove 413 are misaligned, the protrusion 343 can abut against the end surface of the accommodating cavity 410, preventing the second connector 300 from falling out of the accommodating cavity 410.

[0047] Reference Figure 11 As shown, it should be understood that the clearance groove 413 is preferably formed in the upper portion of the accommodating cavity 410. After the protrusion 343 passes through the accommodating cavity 410, the third movable part 350 is rotated so that the protrusion 343 faces downward. After the third movable part 350 is provided with the protrusion 343, its center of gravity is located on the side close to the protrusion 343. When the protrusion 343 is set downward, the third movable part 350 tends to remain in the state with the protrusion 343 facing downward when not affected by external forces. Under non-human conditions, the protrusion 343 is difficult to rotate to align with the upper clearance groove 413, ensuring that the protrusion 343 can reliably restrain the third movable part 350 and prevent the second connecting member 300 from escaping the accommodating cavity 410.

[0048] Reference Figure 10As shown, it can be understood that the brake plate 100 is provided with a penetrating step hole 110, and the first connecting member 200 is provided with a boss 220 at one end close to the brake plate 100. The first connecting member 200 is passed through the step hole 110, and the boss 220 abuts against the brake plate 100.

[0049] To facilitate machining of the brake plate 100, the first connector 200 is designed to be detachably connected to the brake plate 100. A boss 220 is provided on the end of the first connector 200 that is closest to the brake plate 100, and a clamping head 210 is provided on the end of the first connector 200 that is further away from the brake plate 100. During assembly, simply insert the end of the first connector 200 with the clamping head 210 through the stepped hole 110. The boss 220 will then be blocked by the stepped hole 110, effectively abutting the brake plate 100.

[0050] Reference Figure 10 and Figure 11 As shown, it can be understood that the first connecting member 200 is fitted with a second elastic member 230, and a limiting groove 414 is provided on the end face of the accommodating cavity 410 away from the brake plate 100. When the protrusion 343 is placed in the limiting groove 414, one end of the second elastic member 230 contacts the boss 220, and the other end of the second elastic member 230 contacts the step hole 110, and the second elastic member 230 is in a compressed state.

[0051] Before the protrusion 343 passes through the accommodating cavity 410, the second elastic member 230 has already contacted the stepped hole 110 and continues to push the second connecting member 300 so that the protrusion 343 passes through the accommodating cavity 410. At this time, the second elastic member 230 is blocked by the stepped hole 110 and compressed, generating an elastic force. When the moving protrusion 343 is aligned with the limiting groove 414, the protrusion 343 can fall into the limiting groove 414. At this time, the second elastic member 230 should be partially reset, but still in a compressed state. Therefore, the elastic force generated by the second elastic member 230 keeps the protrusion 343 in the limiting groove 414. The protrusion 343 is blocked by the limiting groove 414 and cannot rotate to align with the clearance groove 413. The second connecting member 300 cannot escape from the accommodating cavity 410. The second elastic member 230 can be a spring or an elastic rubber pad.

[0052] It should be understood that the above Figures 3 to 11 The structures shown are all mounting structures between the brake plate and the mounting seat. Multiple similar mounting structures can be provided between the brake plate and the mounting seat to ensure that the brake plate is stably mounted on the mounting seat.

[0053] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the scope of the present invention.
