Description

Technical Field

[0001] The invention belongs to the technical field of motor magnetic steel assembly auxiliary equipment, in particular to a magnetic steel bonding tool and method. Background Art

[0002] When assembling the motor, the magnet and the motor iron cylinder are generally assembled by bonding. During the actual assembly, the following issues need to be considered:

[0003] 1. The different angles of the fixed positions of the magnet and the iron cylinder will cause different angles of the magnetic field generated by the magnet in the iron cylinder. When the rotor winding and the commutator are fixed, the angle of the magnet needs to be calculated, so a positioning device that can move and rotate is required.

[0004] 2. The rotor chips have different thicknesses and the magnets have different heights, so a positioning device that can move up and down is required to adjust the position of the magnets and the rotor chips.

[0005] 3. Different magnets have different arch heights, and the edges at both ends of the magnet width will form different angles. Therefore, it is necessary to adjust the shape and size of the positioning block to better fix the magnet and the iron cylinder during the transfer process.

[0006] 4. When the magnet and the motor iron cylinder are bonded with glue, a tool is required to press the magnet tightly against the iron cylinder until the glue solidifies.

[0007] In the prior art, when installing the magnet, the magnet card is pressed between the two magnets to open the two magnets and fit them tightly against the iron cylinder. The magnet card is disposable, which causes waste of materials. Pressing the magnet card also wastes manpower and adds two processes. In addition, different solutions need to be adjusted during the development and design of the motor. If new tooling is processed every time, it will waste time and money, delaying the development cycle.

[0008] Therefore, it is necessary to study a magnetic steel installation tool and installation method that is convenient for adjusting the relative position (height direction and circumferential direction) of the magnetic steel and the motor iron cylinder, and is convenient for pressing and fixing the magnetic steel, and has high versatility.

[0047] The present invention discloses a sticky magnetic steel tooling, as shown in the attached Figure 1-6, comprising a die base 1, wherein the die base 1 is used to install the magnetic steel and the motor iron cylinder when in use, so that the magnetic steel and the motor iron cylinder are assembled on the die base 1, wherein one end face of the die base 1 is a magnetic steel positioning surface 15 for positioning one end face of the magnetic steel, and two positioning blocks 2 are arranged on the magnetic steel positioning surface 15 of the die base 1, and the two positioning blocks 2 are symmetrically distributed, and the area between the two positioning blocks 2 and the magnetic steel positioning surface 15 jointly form a cavity for accommodating the magnetic steel; in addition, an adjusting ring 3 that can rotate and slide is sleeved on the outer wall of the die base 1, One end face of the adjusting ring 3 is an iron cylinder positioning face 31 for positioning one end face of the motor iron cylinder. A circumferential scale 121 and a vertical scale 122 are provided on the outer side wall of the mold base 1. The adjusting ring 3 can adjust the circumferential position on the mold base 1 according to the circumferential scale 121, and can adjust the vertical position according to the vertical scale 122. A fixing device is provided on the adjusting ring 3 to fix the adjusting ring 3 on the outer side wall of the mold base 1, and the fixing device can fix the adjusted position of the adjusting ring 3. The adhesive magnetic steel tooling of the present invention provides an installation reference for the installation of the magnetic steel by setting a magnetic steel positioning surface 15 and a positioning block 2, and can also well limit the installation of the magnetic steel. Through the design of the adjusting ring 3, the position of the adjusting ring 3 can be adjusted according to the matching position of the motor iron cylinder and the magnetic steel, and in conjunction with the design of the circular scale 121 and the vertical scale 122, which is equivalent to adjusting the position of the motor iron cylinder (the motor iron cylinder will be installed on the adjusting ring 3 later), thereby realizing the mutual determination of the position of the motor iron cylinder and the magnetic steel. By setting scales in different directions, the adjustment is made more precise. By setting a fixing device, when adjusted to a suitable position, the position of the adjusting ring 3 can be conveniently fixed.

[0048] One embodiment of the present invention is that the mold base 1 includes an inner core shaft 11 and an outer sleeve 12. When in use, the inner core shaft 11 and the outer sleeve 12 are assembled and connected, wherein the outer sleeve 12 is sleeved on the inner core shaft 11, and one end of one end of the inner core shaft 11 is provided with a flange 13, and the flange 13 is provided with a through hole 14. One end of the outer sleeve 12 is provided with a flange extending outward, and an adjusting bolt is connected in the through hole 14, and one end of the adjusting bolt is pressed against the lower end surface of the flange. In this way, the relative position of the inner core shaft 11 and the outer sleeve 12 in the axial direction can be adjusted, and it can adapt to the installation of motors of different models. In this embodiment, the upper end surface of the outer sleeve 12 is a magnetic steel positioning surface 15, and one end of the inner core shaft 11 protrudes from the magnetic steel positioning surface 15 and is installed with two fastening springs 4, and one end of the fastening spring 4 is provided with an elastic bending section extending outward along the radial direction of the inner core shaft 11, and the fastening spring 4 presses the magnetic steel to be installed from the inside to the outside along the radial direction through the elastic bending section. The fastening spring sheet 4 can compress the magnetic steel by its own elasticity, which is convenient for bonding the magnetic steel to the motor iron cylinder. The end of the elastic bending section is bent inward and forms a convex arc-shaped pressing surface 41 at the bending position, as shown in the attached figure. In this way, the outermost side of the fastening spring sheet 4 is an arc-shaped surface. In actual use, whether inserting or removing the magnetic steel, it will not interfere with the movement of the magnetic steel, which is convenient to operate. Moreover, by pressing the arc-shaped surface on the magnetic steel, the damage to the magnetic steel can be reduced.

[0049] In order to adapt to the assembly of motors of different specifications (magnets of different specifications and sizes), the fastening spring clip 4 and the positioning block 2 in the present invention are both replaceable components; one end of the inner core shaft 11 is provided with two spring clip positioning holes 5 for inserting the fastening spring clip 4, and one end of the fastening spring clip 4 is inserted into the spring clip positioning hole 5. The fastening spring clip 4 and the inner core shaft 11 are plug-in connected, which is convenient for installation. The fastening spring clip 4 can be replaced to meet the installation requirements of different magnets. Two positioning columns 6 are provided on the magnetic steel positioning surface 15, and a mounting hole is opened on the positioning block 2. The positioning block 2 is fixed on the positioning column 6 by inserting through the mounting hole. The mounting hole can be set as a blind hole or a through hole when it is actually set, and the positioning block 2 is installed by plug-in, which is convenient for installation and replacement. Such a structural design enables the adhesive magnetic steel tooling of the present invention to adapt to the installation of motor magnetic steels of different models, and when arranging the positioning column 6, a symmetrical distribution or an asymmetrical distribution structure can be selected, so that cavities of different sizes for accommodating magnetic steels can be formed according to needs, which can further adapt to the installation of magnetic steels of different shapes and sizes.

[0050] In order to facilitate the definition of the position of the motor iron cylinder, a positioning boss 32 is provided on the iron cylinder positioning surface 31 of the adjusting ring 3 of the present invention, and a positioning groove is provided at one end of the motor iron cylinder. When installing, the positioning groove of the motor iron cylinder is embedded in the positioning boss 32. See the attached Figure 5 , to limit the position of the motor iron cylinder, and then to ensure the installation position of the motor iron cylinder and the magnetic steel. It should be noted that when the motor iron cylinder is not installed on the adjusting ring 3, the positioning boss 32 is used as a reference to adjust the position of the adjusting ring 3. Since the position of the positioning block 2 is also fixed, the adjusting ring 3 is adjusted to the corresponding position and then fixed, and then the motor iron cylinder and the magnetic steel are installed to ensure the relative position of the motor iron cylinder and the magnetic steel.

[0051] The fixing device in the present invention comprises a plurality of positioning screws 7 installed on the adjusting ring 3 along the radial direction of the adjusting ring 3. In this way, the fixing device can realize multi-point tightening of the adjusting ring 3, so that the position of the adjusting ring 3 is fixed firmly.

[0052] The present invention also discloses a magnetic steel bonding method, which uses the above-mentioned magnetic steel bonding tooling, and includes the following steps:

[0053] Step 1: According to the matching position of the motor iron cylinder and the magnetic steel, adjust the adjusting ring 3 to the corresponding position along the circumferential scale 121 and the vertical scale 122 on the outer wall of the outer sleeve 12. At this time, the adjustment of the adjusting ring 3 is mainly based on the position of the positioning boss 32 and the positioning block 2. The position of the adjusting ring 3 can be accurately controlled by the circumferential scale 121 and the vertical scale 122. When the adjusting ring 3 is adjusted to the correct position, the adjusting ring 3 is fixed at this position by the fixing device. The fixing device in this embodiment includes a plurality of positioning screws 7 installed on the adjusting ring 3 along the radial direction of the adjusting ring 3. In this way, the fixing device can achieve multi-point tightening and fix the position of the adjusting ring 3 firmly;

[0054] Step 2: Position the motor iron cylinder through the positioning boss 32 on the adjusting ring 3 and fix the position of the motor iron cylinder; wherein the motor iron cylinder is provided with a positioning groove that cooperates with the positioning boss 32, and the motor iron cylinder is embedded in the positioning boss 32 through the positioning groove to realize the installation of the motor iron cylinder on the adjusting ring 3;

[0055] Step 3: Install the magnet. One end face of the magnet is positioned and installed through the magnet positioning surface 15. The outer wall of the magnet fits the inner wall of the iron cylinder that has been fixed and installed in step 2. The position of the magnet in the circumferential direction is limited by the positioning block 2. The installation position of the magnet is mainly limited by the magnet positioning surface 15, the positioning block 2 and the motor iron cylinder. During actual assembly, the magnet positioning surface 15, the positioning block 2 and the motor iron cylinder will form an installation cavity, and the magnet can be inserted into the cavity.

[0056] Step 4: Add glue between the motor iron cylinder and the magnetic steel, and press the magnetic steel against the inner wall of the motor iron cylinder by fastening the spring sheet 4; the structure of the fastening spring sheet 4 is described in the above tooling. In actual use, the fastening spring sheet 4 presses against the inner side of the magnetic steel (arc-shaped structure) through its own elastic action, so that the outer side wall of the magnetic steel fits tightly with the outer side wall of the motor iron cylinder; this facilitates the bonding of the motor iron cylinder and the magnetic steel by glue;

[0057] Step 5: After the magnet is glued to the motor iron cylinder by glue, the magnet and the iron cylinder are removed from the tooling together, completing the installation of the magnet in the motor iron cylinder. The structure of the fastening spring 4 can guide the magnet during the process of loading and removing the tooling to avoid interference.

[0058] The present invention improves the process of sticking magnetic steel, saves the use of materials, and wastes labor costs. In addition, the device has good compatibility, can adjust the angle and height, and can adapt to different magnetic steel installations, etc., realizing multiple uses of one device.

[0059] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
