Description

Technical Field

[0001] This technical solution relates to the field of motor assembly equipment technology, specifically to a bearing press-fitting device and a stainless steel permanent magnet motor assembly equipment having the device. Background Technology

[0002] In the existing assembly process of stainless steel permanent magnet motors, the rotor, shaft, and bearing are first assembled to form a rotor assembly. Then, the bearing in the rotor assembly is pressed into the base of the motor housing to achieve a stable fit between the bearing and the base, thereby completing the assembly of the rotor assembly and the base. Currently, the common solution used in the industry for the assembly process of pressing the bearing into the base is to press the ends of the shaft and rotor downwards with external force, and indirectly drive the bearing to move axially by means of the assembly relationship between the shaft and the bearing, thereby completing the press fit between the bearing and the base.

[0003] However, the existing pressing method still has some shortcomings:

[0004] 1. The existing press-fitting method that uses a rotating shaft as the force transmission carrier will cause the axial force generated during the press-fitting process to be transmitted to the inside of the bearing through the rotating shaft. As a result, the entire bearing has to bear the entire press-fitting load. This can easily cause wear, jamming or displacement of the steel balls inside the bearing. It may also cause deformation or even structural damage to the inner and outer rings of the bearing, affecting the assembly accuracy and service life of the bearing. In turn, it will lead to a decrease in the overall transmission performance of the stainless steel permanent magnet motor, an increase in operating noise, and ultimately affect the assembly quality of the motor product.

[0005] 2. Traditional press-fitting devices cannot simultaneously configure a support structure for vertical positioning of the rotor assembly and a press-fitting mechanism to meet the requirements of downward pressing assembly. Therefore, traditional press-fitting devices abandon the support structure, and the rotor assembly can only rely on the cooperation constraint between the bearing and the base to achieve passive support. The rotor assembly lacks effective support during the press-fitting process, and is prone to tilting and offset posture deviations during press-fitting, which ultimately leads to insufficient press-fitting accuracy and damage to components such as bearings and shafts. Summary of the Invention

[0006] The purpose of this technical solution is to provide a bearing press-fitting device and a stainless steel permanent magnet motor assembly equipment with the device. The rotor assembly is clamped by a rotor clamping mechanism, and then the press-fitting drive mechanism acts on the press-fitting head mechanism. The press-fitting head mechanism presses against the outer ring of the bearing and presses the bearing into the base.

[0018] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0019] 1. This technical solution simultaneously includes a press-fitting drive mechanism for press-fitting the bearing and a rotor clamping mechanism for supporting the rotor assembly. The press-fitting head mechanism is also equipped with a press-fitting head assembly to transmit the pressure of the press-fitting drive mechanism to the upper end of the bearing. The rotor clamping mechanism supports and positions the middle part of the rotor assembly. The press-fitting head assembly can transmit the pressure of the press-fitting drive mechanism located in the upper half of the rotor assembly to the outer ring of the bearing located in the lower half of the rotor assembly, thereby realizing the press-fitting of the bearing. At the same time, it avoids structural interference between the downward press-fitting operation of the press-fitting drive mechanism and the supporting operation of the rotor clamping mechanism, ensuring the stability of the bearing press-fitting device.

[0020] 2. This technical solution supports and positions the rotor assembly through a rotor clamping mechanism, and then the press-fitting drive mechanism applies driving force to the press-fitting head mechanism located at the rotor clamping mechanism, so that the press-fitting head mechanism presses against the outer ring of the bearing and completes the press-fitting of the bearing. This press-fitting method acts directly on the outer ring of the bearing and the force is uniform, which improves the assembly accuracy and press-fitting stability of the bearing and the base, and ensures the reliability of bearing operation and the overall transmission performance and service life of the stainless steel permanent magnet motor.

[0021] 3. This technical solution involves sliding the press-fit head assembly onto the two gripper heads of the rotor clamping mechanism. When the two gripper heads approach each other to clamp the rotor assembly, the press-fit head body is located at the upper end of the outer ring of the bearing. Driven by the press-fit drive mechanism, the press-fit head body can slide on the gripper heads, thereby pressing the press-fit head body against the outer ring of the bearing to achieve press-fitting of the bearing outer ring. The structure is compact, saves installation space, and ensures that the press-fitting force is applied to the outer ring of the bearing. This improves the problem of the bearing press-fitting device having a scattered structure, occupying a large amount of equipment layout space, resulting in a messy overall layout and low space utilization of the motor assembly station.

[0022] 4. This technical solution uses a barrel clamping device to hold the barrel, and a positioning rod to position the rotor assembly shaft to achieve rotor assembly positioning. When the drive component moves the lifting frame downward, the pressing component at the lower end of the lifting frame presses down the barrel simultaneously, so that the barrel is sleeved on the outside of the rotor assembly. At the same time, during the pressing process of the pressing component moving down to achieve barrel pressing, the drive component drives the positioning rod to move upward along the lifting frame, so that the positioning rod and the rotor assembly on the base platform are relatively stationary, avoiding shaft displacement or damage during pressing, ensuring the coaxial assembly accuracy of the barrel and rotor assembly, and improving the stability and reliability of motor assembly.

[0042] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0043] Combination Figure 2 and Figure 4 A bearing press-fitting device, comprising:

[0044] The base placement platform 21 is installed on the frame 1. The base placement platform 21 is used to place the base 104. The base 104 is placed on the base placement platform 21 by manual or robotic arm first, and then the rotor assembly 100 is placed on the base placement platform 21. The rotor assembly 100 is placed on the upper end of the base 104. The base placement platform 21 is provided with a positioning groove 211 that matches the shape of the base 104. The positioning groove 211 ensures the stability of the base 104.

[0045] The rotor clamping mechanism 3 is located on the side of the base placement platform 21. The rotor clamping mechanism 3 is mounted on the frame 1. The rotor clamping mechanism 3 is used to support the rotor assembly 100 located on the base placement platform 21. The rotor clamping mechanism 3 can clamp the rotor assembly 100 to prevent the rotor assembly 100 from tilting or deviating from the set angle, and ensure that the rotor assembly 100 is placed vertically.

[0046] The press-fitting head mechanism 4 is movably mounted on the rotor clamping mechanism 3. The press-fitting head mechanism 4 is used to abut against the outer ring of the bearing 101 on the rotor assembly 100.

[0047] The press-fitting drive mechanism 5 is located above the base placement platform 21. The press-fitting drive mechanism 5 movably abuts against the press-fitting head mechanism 4. The press-fitting drive mechanism 5 is used to drive the press-fitting head mechanism 4 to move and press the bearing 101 of the rotor assembly 100 of the rotor clamping mechanism 3 into the base 104. The driving force of the press-fitting drive mechanism 5 acts on the press-fitting head mechanism 4, and then the press-fitting head mechanism 4 acts on the outer ring of the bearing 101, so that the outer ring of the bearing 101 can be placed in the base 104.

[0048] During the process of pressing the bearing 101 onto the base 104, the rotor assembly 100 can overcome the clamping force of the rotor clamping mechanism 3 and move on the rotor clamping mechanism 3. That is, the driving force applied by the pressing drive mechanism 5 to the outer ring of the bearing 101 is greater than the clamping force of the rotor clamping mechanism 3 on the rotor assembly 100. The rotor clamping mechanism 3 plays a supporting role for the rotor assembly 100, preventing the rotor assembly 100 from tipping over. The rotor clamping mechanism 3 will not clamp the rotor assembly 100 to the point that it cannot move at all.

[0049] Combination Figures 2-5 The pressing head mechanism 4 includes two pressing head assemblies 41 arranged opposite to each other. The two pressing head assemblies 41 are slidably arranged on the two jaw heads 34 of the rotor clamping mechanism 3, that is, each jaw head 34 of the rotor clamping mechanism 3 is provided with a pressing head assembly 41.

[0050] Press head assembly 41 includes:

[0051] The press-fitting base 42 is movably mounted on the rotor clamping mechanism 3;

[0052] The press head body 43 is installed at the lower end of the press seat 42 and is used to abut against the outer ring of the bearing 101.

[0053] Guide rod 44 is connected to press base 42, and guide rod 44 is slidably mounted on the gripper head 34 of rotor clamping mechanism 3;

[0054] The elastic element 45 has its two ends connected to the pressing seat 42 and the gripper head 34 of the rotor clamping mechanism 3, respectively. The elastic element 45 is used to make the pressing head body 43 have a tendency to move closer to the pressing drive mechanism 5, so that the pressing head body 43 moves closer to the lower end of the gripper head 34 to achieve reset.

[0055] Combination Figure 4 and Figure 5 The press-fit base 42 includes:

[0056] A horizontal plate 421 is connected to the upper end of the guide rod 44, and the horizontal plate 421 is located above the gripper head 34 of the rotor clamping mechanism 3.

[0057] The connecting plate 422 is connected to the horizontal plate 421 at its upper end, and the connecting plate 422 is vertically arranged and located to the side of the gripper head 34 of the rotor clamping mechanism 3.

[0058] The second horizontal plate 423 is connected to the lower end of the connecting plate 422. The first horizontal plate 421, the connecting plate 422 and the second horizontal plate 423 form a "C" shaped pressing seat 42. The second horizontal plate 423 is connected to the pressing head body 43, and the second horizontal plate 423 is connected to the lower end of the guide rod 44. The second horizontal plate 423 is located below the gripper head 34 of the rotor clamping mechanism 3.

[0059] Among them, the elastic element 45 is a spring, disc spring or rubber ring. The elastic element 45 is sleeved on the guide rod 44, and the two ends of the elastic element 45 abut against the lower end of the first horizontal plate 421 and the upper end of the gripper head 34 respectively. The elastic force of the elastic element 45 makes the first horizontal plate 421 move away from the upper end of the gripper head 34 and makes the second horizontal plate 423 move closer to the lower end of the gripper head 34; or, the elastic element 45 is a tension spring or rubber band. The elastic element 45 connects the upper end of the second horizontal plate 423 and the lower end of the gripper head 34.

[0060] like Figure 4 The press head body 43 is provided with a clearance opening 431, which is used to avoid the outer ring of the bearing 101. The side wall of the outer ring of the bearing 101 can be placed in the clearance opening 431 or abut against the inner wall of the clearance opening 431. The lower edge of the clearance opening 431 has a press part 432, which is a ridge or a press protrusion. The press part 432 is used to abut against the upper end of the outer ring of the bearing 101, so that the bearing 101 can be pressed into the base 104 from top to bottom.

[0061] The end of the horizontal plate 421 is provided with a relief groove 4211, which is used to avoid the upper part of the rotor assembly 100, that is, the rotor 103 of the rotor assembly 100 is placed in the relief groove 4211 to avoid pressing against the end of the horizontal plate 421.

[0062] The press head body 43 is detachably mounted on the end of the horizontal plate 423 by screws, pins or bolts. By replacing the press head body 43 with different models, the size of the clearance opening 431 and the press part 432 can be changed, thereby adapting to the press-fitting of bearings 101 of different sizes.

[0063] Combination Figures 2-5 The rotor clamping mechanism 3 includes:

[0064] The first movable component 31 is located beside the base placement platform 21. The first movable component 31 is mounted on the frame 1. The first movable component 31 can drive the gripper head 34 and the pressing head assembly 41 to be positioned or moved away from the base placement platform 21.

[0065] The sliding frame 32 is slidably mounted on the moving component 31 and can move closer to or further away from the base placement platform 21 under the drive of the moving component 31.

[0066] The clamping drive unit 33 is a cylinder or a hydraulic cylinder, which is mounted on the sliding frame 32. The clamping drive unit 33 has a drive end on each of its opposite sides, and the two drive ends are respectively equipped with a gripper head 34. Each gripper head 34 is equipped with a press head assembly 41.

[0067] When the clamping drive 33 drives the two gripper heads 34 to move closer to each other, the pressing head assembly 41 moves synchronously with the movement of the gripper heads 34, that is, the two pressing head assemblies 41 also move closer to each other, and at the same time, the pressing head assembly 41 can slide on the gripper heads 34 along a direction perpendicular to the movement of the gripper heads 34.

[0068] The gripper head 34 and the sliding frame 32 are slidably connected by the second slide rail 35 and the second slider 36, thereby ensuring the stability of the movement of the gripper head 34 and ensuring that the structure of the gripper head 34 is stable and firm when the pressing drive mechanism 5 drives the pressing head mechanism 4 located on the gripper head 34 to perform pressing.

[0069] Combination Figure 4 and Figure 5 The gripper head 34 includes a gripper seat 341 and a gripping part 342. The gripper seat 341 is connected to the drive end of the gripping drive member 33. The gripping part 342 is installed at the end of the gripper seat 341. The gripping part 342 is provided with a gripping groove 3421. The gripping groove 3421 is a V-shaped groove. The gripping part 342 is made of silicone, rubber or sponge material.

[0070] Combination Figure 4 and Figure 5 The mobile component 31 includes:

[0071] The mounting base plate 311 is mounted on the workbench 11 of the frame 1;

[0072] Guide rail 312 is mounted on mounting base plate 311;

[0073] Slider 313 is slidably mounted on guide rail 312, and slider 313 is provided with sliding frame 32;

[0074] The drive component 314, which is a pneumatic cylinder, hydraulic cylinder or electric cylinder, is mounted on the sliding frame 32 and the drive end of the drive component 314 is connected to the worktable 11 of the frame 1. The drive component 314 drives the sliding frame 32 to move on the mounting base plate 311, thereby enabling the sliding frame 32 to move closer to or further away from the base placement platform 21.

[0075] Combination Figure 2 and Figure 3 The press-fitting drive mechanism 5 includes:

[0076] Support frame 51 is mounted on frame 1;

[0077] The lifting plate 52 is slidably mounted on the support frame 51, and the lifting plate 52 is movably positioned above the base placement platform 21.

[0078] The pressure cylinder 53 is installed at the lower end of the lifting plate 52. The pressure cylinder 53 is used to press against the upper end of the horizontal plate 421 of the pressing seat 42, and the middle part of the pressure cylinder 53 can avoid the upper half of the rotor assembly 100.

[0079] The second driving component 54 is an electric cylinder, hydraulic cylinder, or pneumatic cylinder, which is mounted on the first support frame 51. The driving end of the second driving component 54 is connected to the first lifting plate 52, and is used to drive the first lifting plate 52 to move vertically on the first support frame 51.

[0080] like Figure 1 A stainless steel permanent magnet motor assembly equipment, comprising:

[0081] A frame 1, on which a workbench 11 is mounted;

[0082] The bearing pressing device 2 is installed on the workbench 11 of the frame 1. The bearing pressing device 2 is used to press the rotor assembly 100 onto the base 104. Specifically, it presses the bearing 101 of the rotor assembly 100 into the base 104, so that the outer ring of the bearing 101 and the base 104 are connected by interference fit.

[0083] The barrel placement platform 6 is installed on the workbench 11 of the frame 1 and is located next to the base placement platform 21 of the bearing pressing device 2. The barrel 105 is placed on the barrel placement platform 6 by manual or robotic arm to realize the feeding of the barrel 105. The barrel placement platform 6 is provided with a placement groove that is adapted to the lower half structure of the barrel 105.

[0084] The barrel clamping device 7 is installed on the worktable 11 of the frame 1. The barrel clamping device 7 is used to clamp the barrel 105 located on the barrel placement table 6, so as to remove the barrel 105 from the barrel placement table 6.

[0085] The barrel pressing device 8 is mounted on the frame 1. The barrel pressing device 8 is used to press the barrel 105 held by the barrel clamping device 7 onto the outside of the rotor assembly 100 on the base placement platform 21.

[0086] The moving device 9 is mounted on the frame 1 and is connected to the base placement platform 21 and the barrel placement platform 6. The moving device 9 is used to drive the base placement platform 21 and the barrel placement platform 6 to move on the frame 1 to a set position.

[0087] After the barrel clamping device 7 clamps the barrel 105 located on the barrel placement platform 6, the moving device 9 drives the base placement platform 21 and the barrel placement platform 6 to move, so that the base placement platform 21 moves to below the barrel 105 clamped by the barrel clamping device 7, so that the rotor assembly 100 on the base placement platform 21 is located below the barrel 105. Then, the barrel 105 is pressed onto the outside of the rotor assembly 100 by the barrel pressing device 8.

[0088] like Figure 1 The rotor assembly 100 includes a rotor 103, a shaft 102, and a bearing 101. The rotor 103 is located on the outer side of the middle part of the shaft 102. The bearing 101 is sleeved on the end of the shaft 102. The inner ring of the bearing 101 is connected to the shaft 102, and the outer ring of the bearing 101 is connected to the base 104. The rotor 103, shaft 102, and bearing 101 have been pre-assembled to form the rotor assembly 100. The upper end of the base 104 has a receiving groove for receiving the bearing 101, and the inner wall of the receiving groove can fit against the bearing. The outer ring of 101 abuts (due to different models, the end of the rotating shaft 102 will pass through the bearing 101 and the bottom of the receiving groove. At this time, the positioning groove of the base placement platform 21 can ensure that the end of the rotating shaft 102 is received, or the end of the rotating shaft 102 is flush with the end of the bearing 101 and placed in the receiving groove). This technical solution is used to press the rotor assembly 100 onto the base 104 (specifically, the outer ring of the bearing 101 is connected to the base 104), and press the barrel 105 onto the outside of the rotor assembly 100.

[0102] The lifting plate 85 is slidably mounted on the lifting frame 82;

[0103] A drive assembly 86 is mounted on a lifting frame 82, and its drive end is connected to a lifting plate 85. The drive assembly 86 is used to drive the lifting plate 85 to move on the lifting frame 82. The drive assembly 86 includes a drive component 861 and a ball screw 862. The drive component 861 is a motor and is mounted on the lifting frame 82. The drive end of the drive component 861 is connected to the upper end of the lead screw 865 of the ball screw 862 through a drive wheel 863, a transmission belt, and a driven wheel 864 (i.e., sprocket and chain or gear and rack). The motor of the drive assembly 86 drives the lead screw 865 of the ball screw 862 to rotate. The nut 866 of the ball screw 862 is connected to the lifting plate 85 to realize the lifting operation of the lifting plate 85. Alternatively, the drive assembly 86 can be an electric cylinder, a hydraulic cylinder, or a pneumatic cylinder, and its drive end is directly connected to the lifting plate 85 to drive the lifting plate 85 to lift.

[0104] Positioning rod 87 is installed at the lower end of lifting plate 85, and the lower end of positioning rod 87 extends movably out of the lower end of pressing component 83;

[0105] During the movement of the lifting plate 85 on the lifting frame 82, the lower end of the positioning rod 87 can pass through and extend out of the lower end of the pressing component 83, or the lower end of the positioning rod 87 can retract into the pressing component 83, that is, the positioning rod 87 can move up and down within the pressing component 83.

[0106] The lower end of the positioning rod 87 is provided with a positioning groove 871, which is used for the insertion of the upper end of the rotating shaft 102. The positioning of the rotor assembly 100 is achieved by inserting the upper end of the rotating shaft 102 into the positioning groove 871.

[0107] The lower edge of the press-fit part 83 has a press-fit section 831, which presses against the upper edge of the barrel 105 to press the barrel 105 onto the outside of the rotor assembly 100.

[0108] like Figure 9 The lower end of the press-fit component 83 is detachably equipped with a positioning cylinder 88. The lower end of the positioning cylinder 88 is inserted into the upper end of the machine barrel 105 to position the machine barrel 105, ensuring that the axis of the machine barrel 105 coincides with the axis of the positioning rod 87, thereby ensuring that the axis of the machine barrel 105 and the rotor assembly 100 coincide, and that the machine barrel 105 is accurately fitted onto the outside of the rotor assembly 100.

[0109] The upper end of the press-fit part 83 is provided with a relief groove 832, and the press-fit part 83 is provided with a plurality of snap-fit ​​holes 833 in the circumferential direction.

The upper half of the connecting part 883 slides from the relief hole 834 to the anti-detachment hole 835, so that the anti-detachment part 884 abuts against the upper edge of the anti-detachment hole 835, thereby realizing that the positioning cylinder 88 is installed at the lower end of the press-fitting part 83.

[0111] Combination Figure 2 and Figure 3 The worktable 11 of the frame 1 is provided with a strip hole 12;

[0112] Mobile device 9 includes:

[0113] A sliding plate 91 is slidably mounted on the frame 1. A base placement platform 21 is installed at the upper end of the sliding plate 91, and a connecting block 911 is connected to the lower end of the sliding plate 91. The lower end of the connecting block 911 extends into the lower end of the frame 1 through a strip hole 12.

[0114] Drive component 6 92, which is also a hydraulic cylinder, pneumatic cylinder or electric cylinder, is installed at the lower end of the frame 1, and the drive end of drive component 6 92 is connected to the lower end of connecting block 911.

[0115] Sliding plate 2 93 is slidably mounted on frame 1 and located next to sliding plate 1 91. The upper end of sliding plate 2 93 is equipped with barrel placement platform 6.

[0116] The driving component 7 94 is a cylinder, a hydraulic cylinder, or an electric push rod, which is mounted on the sliding plate 1 91, and the driving end of the driving component 7 94 is connected to the sliding plate 2 93.

[0117] The specific working process of this scheme is as follows: First, the base 104 is placed on the base placement platform 21, and then the rotor assembly 100 is placed on the base 104. The clamping drive 33 of the rotor clamping mechanism 3 drives the two gripper heads 34 to approach each other and vertically restricts the rotor assembly 100 on the base 104. The rotor assembly 100 is placed in the clamping groove 3421. The second drive 54 drives the first lifting plate 52 to approach the base placement platform 21, so that the pressure cylinder 53 moves down and presses against the first horizontal plate 421, thereby compressing the elastic member 45, and then causing the pressing seat 42 to move down on the gripper head 34, so that the pressing part 432 of the pressing head body 43 presses against the upper end of the outer ring of the bearing 101, thereby pressing the bearing 101 into the base 104. During the process of pressing the bearing 101 into the base 104, the rotor assembly 100 can move down between the two gripper heads 34.

[0118] During the pressing of the bearing 101 of the rotor assembly 100 onto the base 104 or after pressing, the barrel 105 is placed on the barrel placement platform 6. The driving component 76 of the barrel clamping device 7 drives the moving jaw 75 to approach the fixed jaw 74 and clamp the barrel 105. Then the driving component 73 drives the lifting plate 72 to move upward so that the lower end of the barrel 105 is separated from the barrel placement platform 6.

[0119] After the bearing 101 of the rotor assembly 100 is pressed into the base 104 and the barrel clamping device 7 clamps the barrel 105, the moving component 31 drives the two gripper heads 34 away from the base placement platform 21, so that the rotor assembly 100 is no longer between the two gripper heads 34. Then, the moving device 9 drives the sliding plate 91 and the sliding plate 93 to move, so that the barrel placement platform 6 moves away from below the moving gripper 75 and the fixed gripper 74, and the base placement platform 21 moves to below the moving gripper 75 and the fixed gripper 74. Even if the base 104 and rotor assembly 100 pressed on the base placement platform 21 are moved to the area below the barrel 105 gripped by the moving jaw 75 and the fixed jaw 74, the positioning rod 87 is driven down by the drive assembly 86 and the upper end of the rotating shaft 102 is inserted into the positioning groove 871 to achieve the positioning of the rotor assembly 100. Then the drive assembly 84 drives the lifting frame 82 and the pressing component 83 to move down, so that the pressing component 83 presses on the upper end of the barrel 105 and presses the barrel 105 onto the outside of the rotor assembly 100.

[0120] During the pressing process of the pressing component 83 pressing down on the barrel 105, the positioning rod 87 moves down with the lifting frame 82, so the drive component 86 drives the positioning rod 87 to move up, thereby making the positioning rod 87 and the rotor assembly 100 relatively stationary. At the same time, during the pressing process of the pressing component 83 pressing down on the barrel 105, when the pressing component 83 abuts against the upper end of the barrel 105, the drive component 73 drives the lifting plate 72 to move down synchronously with the lifting frame 82, so that the barrel 105 and the pressing component 83 move down at the same time, or the moving gripper 75 and the fixed gripper 74 can release the barrel 105 (only serving a supporting function).
