Detailed Description
Embodiment one: referring to fig. 1 to 13, in an embodiment of the present invention, there is provided a magnetic performance testing apparatus for a motor soft magnetic material with an automatic winding function, including:
a base 1;
the tester 2 is arranged on the base 1;
the at least one rotary positioning component 4 is arranged at the top of the tester 2 and is used for horizontally positioning and driving the annular sample piece of the soft magnetic material to be tested to rotate;
the rotary driving assembly 5 is arranged on the base 1 and used for driving the arc plate 6 to rotate, the arc plate 6 is perpendicular to the annular sample piece of the soft magnetic material to be tested, and the arc plate 6 can pass through the annular sample piece of the soft magnetic material to be tested in the rotating process; and a wire supply assembly 7 provided at one side of the arc plate 6 and capable of being maintained vertically upward; wherein, tester 2, rotary positioning subassembly 4, rotation drive subassembly 5 are all unified control by controller 3.
The tester 2 is an electromagnetic property measuring instrument, and can accurately and efficiently evaluate the magnetic property of the soft magnetic material;
the wire supply assembly 7 can simultaneously provide two strands of wires, when the wire supply assembly 7 is used for supplying wires, one ends of the two strands of wires can be attached to an annular sample piece of soft magnetic material to be tested by using an adhesive tape, and then the wire supply assembly 7 is driven to rotate, so that a winding action is realized;
two wires are wound on the annular sample piece of the soft magnetic material to be measured at the same time, wherein one wire is used as an excitation winding and is electrically connected with the tester 2, and the other wire is used as a measurement winding and is electrically connected with the tester 2, so that the measurement of the annular sample piece of the soft magnetic material to be measured can be realized through the tester 2;
it should be noted that, the inner diameter of the annular sample piece of the soft magnetic material to be measured is smaller, and the wire supply assembly 7 must continuously pass through the annular sample piece of the soft magnetic material to be measured to realize the winding action, and in order to meet the requirement of the winding number, the wire supply assembly 7 must be wound with a sufficient amount of wires in advance, which may cause that the wire supply assembly 7 is difficult to pass through the annular sample piece of the soft magnetic material to be measured;
to solve this problem, in the present embodiment, the wire feeding assembly 7 is provided at one side of the arc plate 6, and can be held vertically upward;
that is, in the present embodiment, the length of the wire feeding assembly 7 can be appropriately increased within a limited diameter range so as to have a sufficient position to be wound with a sufficient amount of wire in advance;
the limited diameter range refers to: the inner diameter of the annular sample piece of the soft magnetic material to be tested is smaller, and the wire supply assembly 7 needs to pass through the annular sample piece, so that the outer diameter of the whole wire supply assembly 7 is limited by the annular sample piece of the soft magnetic material to be tested;
therefore, under such a limitation, since the wire feeding assembly 7 can be kept vertically upward, the length of the wire feeding assembly 7 can be appropriately increased.
Even if the length of the wire feeding assembly 7 is long, the wire feeding assembly 7 can still smoothly pass through the annular sample piece of the soft magnetic material to be measured because the wire feeding assembly 7 can keep vertical upwards.
Still further, the wire feeding assembly 7 includes:
a cylinder 71, one side of which is vertically extended with an extension cylinder 72, the extension cylinder 72 being rotatably provided at one side of the arc plate 6;
a rotation shaft 73 rotatably provided in the cylinder 71;
a spool 74 fixed on the rotating shaft 73, and two sections of wires are wound on the spool 74; and a weighting block 75 fixed to the bottom of the cylinder 71.
That is, in the present embodiment, the wire feeding assembly 7 is integrally configured in a shaft-like structure, which has advantages in that:
as many pre-wound strands as possible over a limited diameter range;
in addition, the diameter of the spool 74 may be as small as possible while maintaining rigidity.
In order to ensure that the wire supply assembly 7 can smoothly pass through the annular sample of soft magnetic material to be tested, the extension cylinder 72 is rotatably arranged at one side of the arc plate 6, and can keep the wire supply assembly 7 in a vertical state under the action of the weighting block 75;
of course, as shown in fig. 11-13, the process of the wire supply assembly 7 passing through the annular sample piece of soft magnetic material to be tested is that whether the wire supply assembly 7 is always in a vertical state depends on whether the top of the wire supply assembly 7 interferes with the annular sample piece of soft magnetic material to be tested after the wire supply assembly 7 passes through the annular sample piece of soft magnetic material to be tested;
in order to reduce the interference, after the rotary positioning assembly 4 is used for positioning the annular sample piece of the soft magnetic material to be detected, a distance D exists between the bottom of the annular sample piece of the soft magnetic material to be detected and the horizontal plane where the circle center of the arc plate 6 is located 1 When the weighting block 75 is at the highest position, a distance D exists between the bottom of the weighting block and the horizontal plane where the circle center of the arc plate 6 is located 2 The D is 2 ＞D 1 ；
Furthermore, the distance between the annular sample piece of the soft magnetic material to be tested and the bottom of the wire feeding assembly 7 (when the weight increasing block 75 is at the highest position) should be shortened as much as possible when the wire feeding assembly 7 and the rotary positioning assembly 4 are designed, so as to increase the distance between the annular sample piece of the soft magnetic material to be tested and the top of the wire feeding assembly 7 (when the weight increasing block 75 is at the lowest position);
the motion track of the wire supply assembly 7 passes through the circle center of the annular sample piece of the soft magnetic material to be detected, so that the number of turns of the wire which can be wound in advance by the wire supply assembly 7 can be increased as much as possible;
as a preferred embodiment, a baffle is fixed to the top of the spool 74;
in this embodiment, as shown in fig. 7 and 8, the arc plate 6 includes:
a plate 61 having an opening 62, the plate 61 being capable of passing through the annular sample of soft magnetic material to be measured by providing the opening 62;
a base shaft 63 vertically fixed to one side of the plate body 61 for rotatably connecting the extension cylinder 72 through a bearing; and a guide groove 64 provided on the outer peripheral side of the plate body 61.
In addition, the rotation driving assembly 5 includes:
an arc frame 51 fixed to the base 1;
three guide wheels 52 which are distributed at equal intervals and are rotatably arranged on the arc frame 51, wherein the three guide wheels 52 correspond to the guide grooves 64 so as to jointly bear the plate body 61 and drive the plate body 61 to rotate; and the motor 53 is fixed on the base 1, and the output end of the motor 53 is connected with the two guide wheels 52 positioned at the bottom by adopting belt transmission.
When the arc plate 6 is driven to rotate by the rotary driving assembly 5, at least two guide wheels 52 are ensured to be simultaneously contacted with the arc plate 6 at any moment, so that the stability of the motion of the arc plate 6 is ensured.
In this embodiment, as shown in fig. 3 to 5, the rotary positioning assembly 4 includes:
a chute 41 fixed to the top of the tester 2;
a slide carriage 42 slidably provided in the slide groove 41 and driven by a first telescopic rod 43; and a first rotating wheel 45 and a second rotating wheel 48 arranged on the sliding seat 42, wherein the distance between the first rotating wheel 45 and the second rotating wheel 48 is adjustable.
In addition, the first rotating wheel 45 is rotatably disposed on the first shaft seat 44 and has a rotation power, the first shaft seat 44 is fixed on the sliding seat 42, the second rotating wheel 48 is rotatably disposed on the second shaft seat 46, the second shaft seat 46 is slidably disposed on the sliding seat 42, and a second telescopic rod 47 is disposed between the second shaft seat 46 and the first shaft seat 44.
The distance between the first shaft seat 44 and the second shaft seat 46, that is, the distance between the first rotating wheel 45 and the second rotating wheel 48 can be adjusted through the extension and retraction of the second extension rod 47, so that the outer diameter and the inner diameter of different annular sample pieces of soft magnetic materials to be detected are adapted;
and, the first axle seat 44 and the second axle seat 46 are both arranged on the sliding seat 42, and the position of the sliding seat 42 is adjustable, and the position of the annular sample piece of the soft magnetic material to be measured can be adjusted by adjusting the position of the sliding seat 42, so that the annular sample piece of the soft magnetic material to be measured moves on a horizontal plane until the above requirements are met: the motion track of the wire supply assembly 7 passes through the circle center of the annular sample piece of the soft magnetic material to be detected.
It should be noted that in practice, the number of the rotary positioning members 4 is configured to be 1-3, and no matter what the number of the rotary positioning members 4 is, it should be located at one side of the annular sample of soft magnetic material to be tested so as not to interfere with the wire feeding member 7.
As a preferred embodiment, the first rotating wheel 45 and the second rotating wheel 48 have the same structure, and the first rotating wheel 45 includes:
wheel body 451;
a ring pad 452 sleeved on the wheel body 451; and a carrying tray 453 fixed to the bottom of the wheel body 451, wherein the outer diameter of the carrying tray 453 is larger than the outer diameter of the ring pad 452.
The ring pad 452 can promote the adaptability of the first rotating wheel 45 and the friction force between the ring pad and the annular sample piece of the soft magnetic material to be tested, so that the ring pad can effectively drive the annular sample piece of the soft magnetic material to be tested to rotate;
and bear the weight of the dish 453 then can lift the annular sample piece of magnetically soft material that awaits measuring in the bottom of the annular sample piece of magnetically soft material that awaits measuring to further promote the stability of the annular sample piece of magnetically soft material that awaits measuring in the rotation process.
The method comprises the following steps:
the first step: two wires are wound on the winding shaft 74 in advance;
and a second step of: horizontally clamping an annular sample piece of the soft magnetic material to be measured by using the rotary positioning assembly 4;
and a third step of: adhering one ends of two wires to an annular sample piece of the soft magnetic material to be tested by using an adhesive tape;
fourth step: the arc plate 6 and the wire supply assembly 7 are driven to rotate by the rotary driving assembly 5, and meanwhile, the annular sample piece of the soft magnetic material to be tested is driven to rotate by the rotary positioning assembly 4, so that a winding action is realized;
fifth step: two wires are wound on the soft magnetic material at the same time, one wire is used as an excitation winding and is electrically connected with the tester 2, the other wire is used as a measurement winding and is electrically connected with the tester 2, and the measurement of the annular sample piece of the soft magnetic material to be measured can be realized through the tester 2.
Embodiment two: referring to fig. 14, a difference from the embodiment is that: in this embodiment, the state adjustment of the wire feeding assembly 7 is optimized, wherein the ratchet wheel 65 is fixed on the base shaft 63, the pawl 76 corresponding to the ratchet wheel 65 is hinged in the extension cylinder 72, and a supporting spring is arranged between the middle part of the pawl 76 and the extension cylinder 72;
and, the specific arrangement of the ratchet 65 and the pawl 76 satisfies: the extension cylinder 72 does not rotate counterclockwise relative to the base shaft;
it should be explained that, when the wire feeding assembly 7 is located on the right side of the annular sample of soft magnetic material to be tested, there may be a force for pulling the wire feeding assembly 7 to approach the annular sample of soft magnetic material to be tested, and this force may cause the wire feeding assembly 7 to deflect and not keep the vertical state, but in this embodiment, this problem can be well solved by providing the ratchet and pawl structure, so that the anticlockwise deflection will not occur in this case.
And the ratchet 65 and pawl 76 are provided so as not to interfere with the clockwise yaw adjustment of the wire feed assembly 7 relative to the base shaft 63 for maintaining the upright position.
The foregoing description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical solution of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
