Description

Technical Field

[0001] This invention relates to the field of motor assembly tooling technology, specifically a motor rotor press-fitting tooling. Background Technology

[0002] An electric motor consists of a rotor and a stator. The rotor includes a rotor shaft, a rotor core, end insulation, and a commutator. Currently, the production process for DC motor rotors in the industry involves three steps: inserting the core into the shaft, pressing the end insulation, and pressing the commutator.

[0003] The existing motor rotor press-fitting process requires fixing the rotor shaft into the rotor core. After the traditional equipment is pressed, the finished product needs to be removed manually, and then the accessories need to be filled before the next finished product can be pressed. This press-fitting method is inefficient because it cannot be cyclical and requires the accessories to be filled one by one before pressing. Therefore, a motor rotor press-fitting fixture is proposed to address the above problems. Summary of the Invention

[0015] The advantages of this invention are:

[0016] 1. By aligning the rotor shaft with the fixed groove and placing it in, the linkage pulls the fixing piece in the slide groove, causing the fixing piece to clamp the rotor shaft. Then, by aligning the center of the rotor core with the limiting position of the rebound piece, the rotor is magnetically fixed into the magnetic suction cylinder. Rotating the rotating block changes the position of the magnetic cylinder, and the limiting piece aligns the position of the press with the position of the magnetic suction cylinder. Then, the press is turned on, and the limiting cylinder at the output end of the press presses downward against the fixed block, causing the lower pressure plate to press down, driving the magnetic suction cylinder downward, and aligning the rotor core with the fixed rotor. The motor rotor is pressed into place by inserting the shaft. When the lower platen presses down, it drives the linkage rod to move downward. The linkage rod contacts the moving linkage component, which releases the restriction on the fixed component, allowing the fixed component to release its fixation on the rotor shaft. When the press rises, the pressed motor rotor detaches from the fixed slot, achieving the effect of automatic detachment of the finished product, thereby improving pressing efficiency. At the same time, the rotating block rotates the lower platen and function box, which have been filled with rotor shaft and rotor core on the other side, to the bottom of the press, realizing the effect of cyclic pressing of the motor rotor, thereby greatly improving pressing efficiency.

[0017] 2. By placing a rotor core inside the hook-shaped block, the rotor core slides through the groove to the position of the magnetic suction cylinder. When the lower pressure plate on one side is pressing, the lower pressure plate moves downward, causing the linkage plate on the extension plate to move downward. The linkage plate moves downward, squeezing the push plate, which in turn causes the lower pressure plate on the other side to press down. The magnetic suction cylinder on the other side is aligned with the position of the rotor core and moves downward, thus magnetically attracting the rotor core and achieving the effect of automatically loading the rotor core, thereby improving the pressing efficiency.

[0044] Please see Figure 1-12As shown, a motor rotor press-fitting fixture includes a support block 1; a rotating rod 2 is fixedly connected to the top of the support block 1; a rotating block 3 is rotatably connected to the rotating rod 2; functional boxes 4 are fixedly connected to both sides of the rotating block 3; a pair of symmetrically distributed limiting plates 5 are fixedly connected to the top of the functional boxes 4, and a sliding groove 6 is provided on one side of the limiting plates 5; a lower pressure plate 7 is slidably connected to the sliding groove 6 via a slider, and a magnetic suction cylinder 8 is fixedly connected to one end of the lower pressure plate 7; a rebound component is provided inside the magnetic suction cylinder 8; a fixing groove 9 and a disassembly groove 10 are respectively provided on the top of the functional boxes 4; a sliding groove 11 is provided on the bottom wall of the fixing groove 9, and the sliding groove 11 is connected to the disassembly groove 10; a sliding groove 11 is provided inside the sliding groove 11. The fixing component; a T-shaped linkage groove 12 is provided on the side wall of the fixing groove 9, and a linkage component is provided in the T-shaped linkage groove 12; the fixing component is fixed by the linkage component; a linkage diagonal rod 50 is fixedly connected to the bottom of the lower pressure plate 7, and the linkage diagonal rod 50 drives the linkage component; a limiting post 13 is fixedly connected to the top of the function box 4, and one end of the limiting post passes through the lower pressure plate 7; the lower pressure plate 7 and the function box 4 are fixedly connected by a spring box, and the spring is sleeved on the outside of the limiting post; a C-shaped rod 14 is fixedly connected to one side of the support block 1; a press 15 is fixedly connected to one side of the C-shaped rod 14, and the press 15 is positioned corresponding to the fixing groove 9; a limiting cylinder 16 is fixedly connected to the output end of the press 15; the top of the lower pressure plate 7 A fixing block 17 is fixedly connected, and the fixing block 17 corresponds to the position of the limiting cylinder 16; the top of the support block 1 is provided with a limiting member, and the positional relationship between the fixing block 17 and the limiting cylinder 16 is controlled by the limiting member; during operation, the rotor shaft is aligned with the fixing groove 9 and placed in it, and then the fixing member in the sliding groove 42 is pulled by the linkage to fix the rotor shaft. Then, the center of the rotor core is aligned with the limiting position of the rebound member, and the rotor is magnetically fixed in the magnetic suction cylinder 8. The rotating block 3 is rotated to change the position of the magnetic cylinder, and the position of the press 15 is aligned with the position of the magnetic suction cylinder 8 by the limiting member; then the press 15 is turned on, and the limiting cylinder 16 at the output end of the press 15 is in contact with the fixing block 17. The downward pressure causes the lower pressure plate 7 to press down, which in turn moves the magnetic suction cylinder 8 downward, aligning the rotor core with the fixed rotor shaft for motor rotor pressing. When the lower pressure plate 7 presses down, it drives the linkage rod 50 downward, which contacts the moving linkage component. The linkage component releases the restriction on the fixing component, allowing the fixing component to release its fixation on the rotor shaft. When the press 15 rises, the pressed motor rotor detaches from the fixing groove 9, achieving the effect of automatic detachment of the finished product, thereby improving pressing efficiency. At the same time, rotating the rotating block 3 rotates the lower pressure plate 7 and the function box 4, which have been filled with the rotor shaft and rotor core on the other side, to the bottom of the press 15, achieving the effect of cyclic pressing of the motor rotor, thereby greatly improving pressing efficiency.

[0045] The rebound component includes a movable column 18; the bottom of the magnetic suction cylinder 8 is provided with a circular groove 19, and the movable column 18 is fixed in the circular groove 19 by a spring; during operation, the position of the rotor core is restricted by the movable column 18 in the magnetic suction cylinder 8, which makes it convenient for the staff to load the rotor core.

[0046] The fixing component includes a fixing cylinder 20; a sliding block 21 is slidably connected in the sliding groove 11, and a pair of symmetrically distributed annular blocks 22 are fixedly connected to the top of the sliding block 21, with the annular blocks 22 corresponding to the position of the disassembly groove 10; a limiting groove is opened on one side of the annular block 22; the fixing cylinder 20 is slidably connected in the limiting groove by a slider, and a pair of symmetrically distributed arc-shaped extrusion plates 25 are connected to the top of the fixing cylinder 20, with the arc-shaped extrusion plates 25 corresponding to the position of the fixing groove 9; during operation, by placing the rotor shaft into the fixing groove 9, the rotor shaft extends into the fixing cylinder 20, and the fixing cylinder 20 is driven by the sliding block 21. As the fixed cylinder 20 moves downward, its pair of arc-shaped extrusion plates 25 come into contact with and rub against the fixed groove 9, shortening the distance between the arc-shaped extrusion plates 25. This friction and extrusion fixes the rotor shaft. After the motor rotor is pressed in, its sliding block 21 moves upward through the linkage, causing the annular block 22 to move upward, which in turn causes the fixed cylinder 20 to move upward. This causes the arc-shaped extrusion plates 25 to move upward, contacting and fixing the rotor shaft. With the annular block 22 moving upward, its top contacts the rotor core, allowing the pressed motor rotor to disengage from the fixed groove 9. This makes it easier for workers to load the rotor shaft and improves pressing efficiency.

[0047] The linkage includes a Z-shaped rod 26; the Z-shaped rod 26 is rotatably connected between the opposite side walls of the T-shaped linkage groove 12 via a rotating rod 27, and one end of the Z-shaped rod 26 extends out of the T-shaped linkage groove 12 and corresponds to the position of the linkage inclined rod 50; one side of the Z-shaped rod 26 is fixedly connected to the side wall of the T-shaped linkage groove 12 by a spring; both ends of the Z-shaped rod 26 are provided with inclined surfaces; one side of the sliding block 21 is provided with an inclined groove 28, and the inclined groove 28 corresponds to the position of the inclined surface; the side walls of the sliding groove 11 are provided with rebound grooves 29, and a pressure block 30 is slidably connected in the rebound groove 29; one side of the pressure block 30 is fixedly connected to one side of the sliding block 21, and the bottom of the pressure block 30 is fixedly connected to the bottom wall of the rebound groove 29 by a spring; the bottom of the slider is provided with a pulling member, and the sliding block 21 is driven to slide by the pulling member; during operation, the lowering member drives the linkage inclined rod 50 to move downward, and the Z-shaped rod 26... The upper end of the Z-shaped rod 26 moves to the right, and the rotating rod 27 of the T-shaped linkage groove 12 acts as a fulcrum, causing the lower end of the Z-shaped rod 26 to move to the left. At the same time, the inclined block of the lower Z-shaped rod 26 separates from the inclined groove 28 of the sliding block 21. The pressure block 30 on the sliding block 21 is fixed to the rebound groove 29 by a spring. The spring force causes the sliding block 21 to move upward, thereby causing the pressed motor rotor to disengage from the fixed groove 9, improving the pressing efficiency. As the lower pressure plate 7 moves upward, its linkage inclined rod 50 separates from the upper Z-shaped rod 26. The spring force on one side of the Z-shaped rod 26 causes the lower Z-shaped rod 26 to move to the right, filling the rotor shaft in the fixed groove 9. Then, the pulling member is pulled, causing the sliding block 21 to move downward, so that the sliding groove 42 of the sliding block 21 contacts the inclined block of the lower Z-shaped rod 26, thereby locking and fixing the rotor shaft.

[0048] The limiting component includes a conical block 31; a first extension post 32 and a second extension post 33 are respectively fixedly connected to the top of the support block 1; the top of the second extension post 33 is rotatably connected to the conical block 31 via a torsion spring, and the conical block 31 is in contact with the first extension post 32; L-shaped rods 34 are fixedly connected to both sides of the lower pressure plate 7, and the L-shaped rods 34 correspond to the positions of the conical block 31; a set of limiting grooves 35 are opened on the top of the support block 1, and the limiting grooves 35 correspond to the positions of the L-shaped rods 34; during operation, the rotating rod 2 is rotated... 7. The lower pressure plate 7 and the function box 4 are rotated, which in turn drives the L-shaped rod 34 to rotate. The L-shaped rod 34 contacts and locks the conical block 31. The L-shaped rod 34 is aligned with the limiting groove 35, so that the output end of the press 15 is aligned with the magnetic suction cylinder 8. When pressing, the L-shaped rod 34 extends into the limiting groove 35 to determine the position. If it cannot extend into the groove, the press 15 is turned off and the pressing is abandoned. This achieves the effect of preventing pressing from occurring if the position is incorrect. The conical block 31 is set by a torsion spring, and the L-shaped rod 34 can push the conical block 31 to rotate.

[0049] The pulling component includes a pull rope 36; the bottom wall of the sliding groove 11 is provided with an L-shaped through groove 37; the bottom of the sliding block 21 is fixedly connected to the pull rope 36, and one end of the pull rope 36 extends out of the L-shaped through groove 37 and is fixedly connected to a handle 38; the corner of the L-shaped through groove 37 is fixedly connected to a guide post 39 through a guide groove, and the guide post 39 corresponds to the bend of the pull rope 36; during operation, the operator pulls the handle 38, which drives the sliding block 21 in the sliding groove 11 to slide downward, so that its rotor shaft is fixed to the equipment, which facilitates the operator to load parts and improves the pressing efficiency.

[0050] A U-shaped rod 40 is fixedly connected to one side of the support block 1; a hook-shaped block 41 is fixedly connected to the top of the U-shaped rod 40; a sliding groove 42 is provided on the top of the hook-shaped block 41, and the sliding groove 42 corresponds to the position of the magnetic suction cylinder 8; a push plate 43 is fixedly connected to one end of the lower pressure plate 7 on one side of the U-shaped rod 40; an extension plate 44 is fixedly connected to one end of the lower pressure plate 7 on one side of the press 15, and a first pair of symmetrically distributed linkage plates 45 are fixedly connected to one side of the extension plate 44; the push plate 43 and the linkage plate 45 are positioned correspondingly; during operation, By placing a rotor core inside the hook-shaped block 41, the rotor core slides through the slide groove 42 to the position of the magnetic suction cylinder 8. When the lower pressure plate 7 on one side is pressing, the lower pressure plate 7 moves downward, causing the linkage plate 45 on the extension plate 44 to move downward. The linkage plate 45 moves downward, squeezing the push plate 43, which in turn causes the lower pressure plate 7 on the other side to press down. The magnetic suction cylinder 8 on the other side is aligned with the position of the rotor core and moves downward, thereby magnetically attracting the rotor core and achieving the effect of automatically loading the rotor core, thus improving the pressing efficiency.

[0051] Both sides of the functional box 4 are fixed with ring handles 46; during operation, the operator can rotate the handles to drive the functional box 4 to rotate, which in turn drives the rotating cylinder to rotate, thus facilitating the operator's operation.

[0052] A finished product box 47 is fixedly connected to one side of the support block 1, and the finished product box 47 corresponds to the position of the functional box 4; a parts box 48 is fixedly connected to one side of the support block 1; during operation, the finished product box 47 corresponds to the position of the functional box 4, and the pressed motor rotor automatically detaches from the functional box 4 and falls into the finished product box 47, which is convenient for the staff to collect. The parts box 48 is designed to facilitate the staff to place the parts that need to be filled.

[0053] The top of the functional box 4 is fixedly connected to the outer shell 49, and the outer shell 49 corresponds to the position of the Z-shaped rod 26. During operation, the outer shell 49 prevents debris from falling into the T-shaped linkage groove 12, thereby jamming the operation of the Z-shaped rod 26.

[0054] Working principle: The rotor shaft is placed into the fixed groove 9, and then the fixing member in the slide groove 42 is pulled by the linkage to fix the rotor shaft. The center of the rotor core is aligned with the limiting position of the rebound member, and then it is magnetically fixed in the magnetic suction cylinder 8. The rotating block 3 is rotated to change the position of the magnetic cylinder, and the position of the press 15 is aligned with the position of the magnetic suction cylinder 8 by the limiting member. Then the press 15 is turned on, and the limiting cylinder 16 at the output end of the press 15 is pressed down against the fixing block 17, thereby pressing down the lower pressure plate 7 and driving the magnetic suction cylinder 8 to move downward, so that the rotor core is aligned with the fixed rotor shaft and inserted for motor rotor pressing. When the lower pressure plate 7 presses down, it drives the linkage inclined rod 50 to move downward, and the linkage inclined rod 50 contacts the moving linkage member. The linkage releases the restriction on the fixing component, allowing the fixing component to release its fixation on the rotor shaft. When the press 15 is raised, the press-fitted motor rotor detaches from the fixing groove 9, achieving the effect of automatic detachment of the finished product, thereby improving the pressing efficiency. At the same time, rotating the rotating block 3 rotates the lower pressure plate 7 and the function box 4, which have been filled with the rotor shaft and rotor core on the other side, to the bottom of the press 15, achieving the effect of cyclic pressing of the motor rotor, thereby greatly improving the pressing efficiency. The movable column 18 in the magnetic suction cylinder 8 restricts the position of the rotor core, making it convenient for workers to fill the rotor core. By placing the rotor shaft into the fixing groove 9, the rotor shaft extends into the fixing cylinder 20. Then, the sliding block 21 drives the fixing cylinder 20 to move downward, and its pair of arc-shaped extrusion plates 25 move downward. The friction between the curved extrusion plates 25 and the fixed groove 9 shortens the distance between them, thereby rubbing and extruding the fixed rotor shaft. After the motor rotor is pressed in, the sliding block 21 moves upward through the linkage, causing the annular block 22 to move upward, which in turn causes the fixed cylinder 20 to move upward, thereby causing the curved extrusion plates 25 to move upward and contact the fixed rotor shaft. With the annular block 22 moving upward, its top contacts the rotor core, allowing the pressed motor rotor to detach from the fixed groove 9, making it easier for workers to load the rotor shaft and improving pressing efficiency. The lower pressing component drives the linkage inclined rod 50 to move downward, contacting the upper end of the Z-shaped rod 26. The upper end of the Z-shaped rod 26 moves to the right, and with the rotating rod 27 of the T-shaped linkage groove 12 as a fulcrum, the Z-shaped rod... The lower end of Z-shaped rod 26 moves to the left, simultaneously separating the inclined block of Z-shaped rod 26 from the inclined groove 28 of sliding block 21. The pressure block 30 on sliding block 21 is fixed to rebound groove 29 by a spring. The spring force causes sliding block 21 to move upward, thus disengaging the press-fitted motor rotor from the fixed groove 9, improving press-fitting efficiency. As the lower pressure plate 7 moves upward, its linkage inclined rod 50 separates from the upper Z-shaped rod 26. The spring force on one side of Z-shaped rod 26 causes the lower Z-shaped rod 26 to move to the right, filling the fixed groove 9 with the rotor shaft. Then, the pulling member is pulled, causing sliding block 21 to move downward, making the sliding groove 42 of sliding block 21 contact the inclined block of Z-shaped rod 26 at the lower end, thereby locking and fixing the rotor shaft.Rotating the rotating rod 27 drives the lower pressure plate 7 and the function box 4 to rotate, which in turn drives the L-shaped rod 34 to rotate. The L-shaped rod 34 contacts and locks into position with the conical block 31. The L-shaped rod 34 is aligned with the limiting groove 35, so that the output end of the press 15 is aligned with the magnetic suction cylinder 8. During pressing, the L-shaped rod 34 extends into the limiting groove 35 to determine the position. If it cannot extend into the groove, the press 15 is turned off, and the pressing is abandoned. This achieves the effect of preventing pressing from occurring if the position is incorrect. The conical block 31 is set by a torsion spring. The L-shaped rod 34 can push the conical block 31 to rotate. By pulling the handle 38, the sliding block 21 in the sliding groove 11 slides downward, fixing the rotor shaft to the equipment. This facilitates the loading of parts and improves pressing efficiency. By placing the rotor core in the hook-shaped block 41, the rotor core will slide through the sliding groove 42 to the position of the magnetic suction cylinder 8, and then press down on one side. When plate 7 is pressed, the lower pressing plate 7 moves downward, causing the linkage plate 45 on the extension plate 44 to move downward. The linkage plate 45 moves downward, squeezing and pushing plate 43, which in turn causes the lower pressing plate 7 on the other side to press down. The magnetic suction cylinder 8 on the other side is aligned with the position of the rotor core and moves downward, thus magnetically attracting the rotor core and achieving the effect of automatically loading the rotor core, thereby improving the pressing efficiency. By turning the handle, the operator can drive the function box 4 to rotate, which in turn drives the rotating cylinder to rotate, making it convenient for the operator to operate. Since the position of the finished product box 47 corresponds to the position of the function box 4, the pressed motor rotor automatically detaches from the function box 4 and falls into the finished product box 47 for easy collection. The parts box 48 is designed to facilitate the placement of parts to be loaded. The outer casing 49 is designed to prevent debris from falling into the T-shaped linkage groove 12, thereby jamming the operation of the Z-shaped rod 26.
