Description

TECHNICAL FIELD

[0001] The utility model relates to motor field, concretely relates to a high-precision quick assembly device for magnetic steel. BACKGROUND

[0002] As an important equipment in modern social production and life, the service life of the motor directly affects the reliability and economy of the equipment. In order to ensure that the motor can work stably in long-term operation and effectively prolong its service life, it is necessary to carry out motor life test. Through this test, the service life of the motor can be evaluated, and the possible failure causes and improvement measures can be analyzed, thereby providing a scientific basis for the selection and use of the motor. This not only helps to improve the reliability and service life of the motor, but also ensures the safe operation of the equipment and reduces the risk of safety accidents caused by motor failure.

[0003] There are two process routes for installing magnetic steel on the inner wall of the motor shell: one is that the magnetic steel has no magnetism, and is assembled into the motor shell and then magnetized as a whole; the other is that the magnetic steel is pre-magnetized, and then assembled into the motor shell. These two assembly process routes have their own advantages and disadvantages.

[0004] In the prior art, the pre-magnetized magnetic steel assembly is mainly manual assembly. However, the manual assembly method has many problems in efficiency and safety. For example: in the manual assembly method, the pre-magnetized magnetic steel has strong magnetism, and during assembly, the magnetic steel is easily attracted to other positions of the motor shell due to the influence of magnetism, thereby causing inaccurate assembly position of the magnetic steel; during manual assembly, due to the strong magnetic force, the hand can be injured if not careful. INVENTION CONTENTS

[0005] The utility model provides a high-precision quick assembly device for magnetic steel, which assembles the magnetic steel into the shell in a semi-automatic manner, and improves the positioning precision and the assembly position precision and efficiency of the magnetic steel.

[0006] The technical scheme for solving the above technical problems is as follows:

[0007] A high-precision quick assembly device for magnetic steel, comprising:

[0008] A machine base, a plurality of first grooves are arranged on the peripheral surface of the machine base at intervals;

[0009] A magnetic steel seat, an axial end surface of the magnetic steel seat is provided with a through hole penetrating through the axial end surface, a plurality of second grooves for accommodating magnetic steel are arranged along the circumference of the magnetic steel seat at intervals, and the second grooves are in communication with the through hole;

[0010] A magnetic conduction component for adsorbing the magnetic steel located in the second groove, the magnetic conduction component cooperates with the through hole;

[0011] The pressure applying part applies pressure to the magnetic steel adsorbed on the magnetic conductive part, and the pressure applying part is sleeved on the magnetic conductive part.

[0012] Further, the base comprises a pedestal and a column, one end of the column is fixed to the pedestal, and the first groove is arranged on the peripheral surface of the column.

[0013] Further, the second groove penetrates the outer peripheral surface of the magnetic steel seat.

[0014] Further, the radial depth of the second groove is at least greater than the sum of the thicknesses of the two magnetic steels.

[0015] Further, the inner diameter of the through hole is greater than the outer diameter of the pressure applying part.

[0016] In the utility model, the magnetic steel is pre-assembled into the second groove on the magnetic steel seat, the magnetic steel is adsorbed on the peripheral surface of the magnetic conductive part, the magnetic steel adsorbed on the peripheral surface of the magnetic conductive part is pressed into the space between the base and the shell by the pressure applying part, since the shell is a metal part, the magnetic steel is adsorbed on the inner peripheral surface of the shell, and since the magnetic steel enters the first groove in the pressing device, the first groove forms a guiding effect on the magnetic steel, so that the precision of the pressing assembly is improved. Since multiple magnetic steels can be pre-assembled in each second groove, the assembly efficiency can be improved. BRIEF DESCRIPTION OF DRAWINGS

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] like Figures 1 to 6 As shown, this utility model discloses a high-precision rapid assembly device for magnets, including a base 1, a magnet base 3, a magnetic guiding component 6, and a pressure applying component 5. Each part and the relationship between them are described in detail below.

[0029] The base 1 has multiple first grooves 1a spaced apart on its circumferential surface. The base 1 includes a base 1b and a column 1c. One end of the column 1c is fixed to the base 1b, and the first grooves 1a are disposed on the circumferential surface of the column 1c. In this embodiment, both the base 1b and the column 1c are made of non-magnetic material, such as nylon. The base 1b is disc-shaped and fixed to a workbench (not shown in the figure). There are four first grooves 1a, which are spaced apart along the circumference of the column 1c. When the magnet 4 is pressed into the housing 2, the first grooves 1a make way for the magnet 4.

[0030] The magnet base 3 is supported by a support frame (not shown in the figure) mounted on the workbench. The magnet base 3 is located above the machine base 1. The axial end face of the magnet base 3 is provided with a through hole 3a that penetrates the axial end face. Multiple second grooves 3b for accommodating magnets 4 are arranged at intervals along the circumference of the magnet base 3. The second grooves 3b are connected to the through hole 3a. The second grooves 3b may not penetrate the outer circumferential surface of the magnet base 3. This structure allows the magnet 4 to be inserted into the second groove 3 along the axial direction of the magnet base 3. However, since the magnetic conductivity of the magnetic conductive component 6 has an adsorption effect on the magnet 4, when inserted along the axial direction, a part of the magnet 4 may first be adsorbed onto the surface of the magnetic conductive component 6. Therefore, in order to facilitate the placement of the magnet 4 into the second groove 3b, the preferred structure is to set the second groove 3b to penetrate the outer circumferential surface of the magnet base 3. This structure allows the magnet 4 to be inserted into the second groove 3 along the radial direction of the magnet base 3. In this way, even if the magnetic conductive component 6 has an adsorption effect, the entire inner surface of the magnet 4 will eventually be adsorbed onto the magnetic conductive component 6.

[0031] The second groove 3b can accommodate one or more magnets 4. In order to improve production efficiency, in this embodiment, the radial depth of the second groove 3b is at least greater than the sum of the thicknesses of the two magnets 4. Before pressing, multiple magnets 4 can be placed in the same second groove 3b, so that these magnets 4 can be pressed with multiple housings 2 respectively.

[0032] The magnetically conductive component 6 attracts the magnet 4 located in the second groove 3b. The magnetically conductive component 6 mates with the through hole 3a. The magnetically conductive component 6 is cylindrical. After being inserted into the through hole 3a, the distance between the magnetically conductive component 6 and the inner wall of the through hole 3a allows the pressure-applying component 5 to pass through. Therefore, the inner diameter of the through hole 3a is larger than the outer diameter of the pressure-applying component 5. One end of the magnetically conductive component 6 is fixed to a bracket (not shown in the figure), which is located above the magnet base 3.

[0033] The pressure-applying component 5 applies pressure to the magnet attracted to the magnetic conductive component 6. The pressure-applying component 5 is loosely fitted on the magnetic conductive component 6, with a clearance fit between the pressure-applying component 5 and the magnetic conductive component 6. The pressure-applying component 5 encloses the pressure sleeve and the driving component (the driving component is not shown in the figure). The pressure sleeve is loosely fitted on the magnetic conductive component 6. The power output end of the pressure sleeve and the driving component is fixed. The driving component can be a linear driving component such as a cylinder or a hydraulic cylinder.

[0034] The assembly process of the magnet 4 and the housing 2 in this utility model is as follows:

[0035] like Figure 2 The housing 2 is fitted with the column 1c to form a hollow sleeve. The housing 2 is supported by the base 1b. The housing 2 is automatically glued to the position where the magnet 4 is bonded inside the housing 2 by an automatic glue application device. The glue application process is existing technology and will not be described in detail here.

[0036] like Figure 3 and Figure 4 The magnet base 3 is located directly above the base 1 and the housing 2. The centers of the magnet base 3, the base 1, and the housing 2 are on the same straight line. Magnets 4 are pushed into the second groove 3b along the radial direction of the magnet base 3. Multiple magnets 4 are placed in each second groove 3b, thus forming multiple sets of pressed magnets along the circumference of the magnet base 3. Since the magnetic guiding component 6 is made of metal, it will automatically attract the magnets 4. The first set of pressed magnets 4-1-1, 4-2-1, 4-3-1, and 4-4-1 located on the innermost side are attracted to the circumferential surface of the magnetic guiding component 6 along the circumference of the magnetic guiding component 6. The pressure applying component 5 is located above the first set of magnets.

[0037] like Figure 5 and Figure 6 The pressure application component 5 is activated and moves downward along the axial direction of the through hole 3a, pushing the first set of magnets 4-1-1, 4-2-1, 4-3-1 and 4-4-1 adsorbed on the circumferential surface of the magnetic guide component 6 to move downward in a straight line along the magnetic guide component 6. The first set of magnets 4-1-1, 4-2-1, 4-3-1 and 4-4-1 are gradually inserted into the space between the first groove 1a of the base 1 and the housing 2. Each first groove 1a positions and guides one magnet, so that each magnet is accurately engaged with the housing 2. After the pressure application component 5 completes the pressing, the pressure application component 5 is reset.

[0038] Since the first set of magnets 4-1-1, 4-2-1, 4-3-1 and 4-4-1 are pressed in, the pressure-applying component 5 is located between the second set of magnets 4-1-2, 4-2-2, 4-3-2 and 4-4-2 and the magnetic conductive component 6. Therefore, due to the obstruction of the pressure-applying component 5, the second set of magnets 4-1-2, 4-2-2, 4-3-2 and 4-4-2 cannot be attracted to the surface of the magnetic conductive component 6. After the pressure-applying component 5 is reset, the second set of magnets 4-1-2, 4-2-2, 4-3-2 and 4-4-2 automatically attract to the surface of the magnetic conductive component 6.

[0039] Remove the housing 2 equipped with magnets from the base 1. After assembling the housing 2 without magnets to the base 1, press the second set of magnets 4-1-2, 4-2-2, 4-3-2, and 4-4-2, which are adsorbed on the surface of the magnetically conductive component 6, into the space between the first groove 1a and the housing 2, following the process described above. Similarly, press the third and fourth sets of magnets into the newly assembled housing 2.
