Description

Technical Field

[0001] This invention relates to the field of rotor testing technology, and in particular to a support structure for a rotor balancing machine for new energy vehicle motors. Background Technology

[0002] When measuring the unbalance of a rotor, a support structure is required to support the rotor. Support structures are divided into hard supports and soft supports. In existing schemes, soft support structures mostly use leaf springs to suspend the vibrating body. The linear law of the elastic modulus of the leaf spring (which conforms to Hooke's law) is used to detect the dynamic balance of the rotor (F = k·x, where F is the elastic force, k is the scaling factor, and x is the deformation).

[0003] The advantages of using the above-mentioned leaf spring suspension are simple structure and easy assembly. However, at the same time, due to the plastic deformation problem of the leaf spring suspension method, after long-term use, the measurement results of the balancing machine will have a relatively large deviation due to the plastic deformation. Moreover, this error is unpredictable and difficult to detect and verify. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a support structure for a rotor balancing machine for new energy vehicle motors that offers a long service life and high measurement accuracy.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions.

[0006] This application provides a support structure for a rotor balancing machine for new energy vehicle motors, comprising:

[0007] Supporting framework;

[0008] The adjustment frame is connected to the support frame via a connecting rod;

[0009] The connecting rod is hinged at one end to the support frame and at the other end to the adjustment frame;

[0010] A positioning frame, connected to the adjustment frame and used for rotor positioning;

[0011] A lifting assembly is used to adjust the height of the positioning frame relative to the adjusting frame;

[0012] There are two connecting rods symmetrically arranged about the positioning frame.

[0013] Further specifying, in the above-mentioned support structure for a rotor balancing machine for a new energy vehicle motor, the support frame has a support cavity for accommodating the adjustment frame, and the end of the adjustment frame away from the ground protrudes to the outside of the support frame.

[0014] Further specifying, in the above-mentioned support structure for a rotor balancing machine for a new energy vehicle motor, the support frame is provided with two first mounting slots symmetrically about the positioning frame and communicating with the support cavity, and the adjustment frame is provided with two second mounting slots at positions corresponding to the two first mounting slots;

[0015] One end of the connecting rod is hinged to the first mounting groove via a first hinge, and the other end is hinged to the second mounting groove at the corresponding position via a second hinge.

[0016] Further specifying, in the aforementioned support structure for a rotor balancing machine for a new energy vehicle motor, the two connecting rods are parallel in the vertical direction.

[0017] Further specifying, in the aforementioned support structure for a rotor balancing machine for a new energy vehicle motor, two positioning wheels are symmetrically and rotatably provided at the corresponding position of the positioning frame away from the support frame.

[0018] Further specifying, in the above-mentioned support structure for a rotor balancing machine for a new energy vehicle motor, the adjusting frame has an accommodating cavity with an opening facing away from the ground for accommodating the positioning frame, and the positioning frame can slide within the accommodating cavity.

[0019] Further specifying, in the aforementioned support structure for a rotor balancing machine for a new energy vehicle motor, the lifting assembly includes a connecting rod disposed between the bottom of the positioning frame and the bottom wall of the accommodating cavity, one end of the connecting rod being rotatably connected to the adjusting frame and the other end being threadedly connected to the positioning frame.

[0020] Further specifying, in the aforementioned support structure for a rotor balancing machine for a new energy vehicle motor, the adjusting frame is provided with a through slot.

[0021] The present invention has at least the following beneficial effects:

[0022] By hinged at both ends of the connecting rod to the support frame and the adjustment frame respectively, the connection between the support frame and the adjustment frame is realized. This means that the mechanical structural characteristics (i.e., dynamic friction coefficient) are used to replace the original leaf spring type soft bearing dynamic balancing machine. The soft bearing dynamic balancing machine is made by utilizing the mechanical properties of materials, which solves the problem of inaccurate measurement results caused by the plastic deformation of the leaf spring. This ensures that the equipment will not produce measurement data distortion even after long-term use, and also expands the load-bearing weight range of the same soft bearing balancing machine.

[0035] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings.

All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0037] The drive device for a rotor balancing machine for a new energy vehicle motor provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0038] like Figures 1-5As shown, this application embodiment provides a drive device for a rotor balancing machine for a new energy vehicle motor, including a base 500, a left drive arm 110 and a right drive arm 120 symmetrically arranged on the base 500 and capable of moving synchronously towards or away from each other, a bracket 200 fixedly arranged on the base 500, a pulley assembly for driving the rotor 810 to rotate, and a rotation drive assembly for driving the pulley assembly.

[0039] The base 500 is provided with a guide rail assembly connected to the left drive arm 110 and the right drive arm 120, and a clamping drive assembly for driving the left drive arm 110 and the right drive arm 120 to move. The guide rail assembly includes a guide rail 710 fixedly mounted on the end face of the base 500 near the left drive arm 110 and the right drive arm 120. Two sliders 720 are slidably mounted on the guide rail 710. A connecting plate 730 is fixedly mounted on the end face of the slider 720 away from the guide rail 710. An adjusting block 740 is fixedly mounted on the end face of the connecting plate 730 away from the slider 720. The left drive arm 110 and the right drive arm 120 are respectively fixedly connected to the two adjusting blocks 740.

[0040] The clamping drive assembly includes a drive connecting plate 650 fixedly mounted on the base 500, a cylinder 660 mounted on the drive connecting plate 650, and two jaws 670 that can move toward or away from each other on the cylinder 660. Two adjusting blocks 740 are fixedly connected to the jaws 670 at the corresponding positions.

[0041] When the cylinder 660 drives the two chucks 670 to move towards or away from each other, the chucks 670 drive the slider 720 to slide on the guide rail 710 through the adjusting block 740, thereby driving the left drive arm 110 and the right drive arm 120 to move towards or away from each other. When the left drive arm 110 and the right drive arm 120 move towards each other, they will drive the pulley assembly to wrap around the rotor 810. The rotation drive assembly can drive the rotor 810 to rotate through the pulley assembly.

[0042] It is understood that the clamping drive assembly is used to drive the left drive arm 110 and the right drive arm 120 to move synchronously towards or away from each other. The coupling method between the jaw 670 and the left drive arm 110 and the right drive arm 120 is not limited to the one mentioned above. For example, the two jaws 670 can be fixedly connected to the corresponding position slider 720 and connecting plate 730 respectively, or the two jaws 670 can be directly connected to the left drive arm 110 and the right drive arm 120 respectively.

[0043] Of course, the structure of the clamping drive assembly is not limited to the one mentioned above. For example, a screw and threaded slider can be used to control the movement of the left drive arm 110 and the right drive arm 120, as long as the left drive arm 110 and the right drive arm 120 can move synchronously towards or away from each other.

[0044] In a preferred embodiment, such asFigures 1-5 As shown, the pulley assembly includes a belt 400 and a drive pulley 610 that is radially coplanar and axially parallel, a first left driven pulley 301, a first right driven pulley 302, a second left driven pulley 303, a second right driven pulley 304, a third left driven pulley 305, a third right driven pulley 306, a fourth left driven pulley 307, a fourth right driven pulley 308, a fifth left driven pulley 309, a fifth right driven pulley 310, a sixth left driven pulley 311, and a sixth right driven pulley 312, wherein the drive pulley 610 is connected to the rotation drive assembly.

[0045] The first left driven pulley 301, the second left driven pulley 303, the third left driven pulley 305, and the fourth left driven pulley 307 are rotatably mounted on the left drive arm 110; the first right driven pulley 302, the second right driven pulley 304, the third right driven pulley 306, and the fourth right driven pulley 308 are rotatably mounted on the right drive arm 120; and the fifth left driven pulley 309, the fifth right driven pulley 310, the sixth left driven pulley 311, and the sixth right driven pulley 312 are rotatably mounted on the bracket 200. Figure 5 As shown, the sixth left driven pulley 311 and the sixth right driven pulley 312 are located above the driving pulley 610 and are symmetrical about the reference axis. The fifth left driven pulley 309 and the fifth right driven pulley 310 are located above the sixth left driven pulley 311 and the sixth right driven pulley 312 and are symmetrical about the reference axis. The distance between the fifth left driven pulley 309 and the fifth right driven pulley 310 and the reference axis is greater than the distance between the sixth left driven pulley 311 and the sixth right driven pulley 312 and the reference axis. The reference axis is the plane of symmetry between the left drive arm 110 and the right drive arm 120.

[0046] The axes of the first left driven pulley 301 and the first right driven pulley 302 are located on the same horizontal plane, and this horizontal plane lies between the horizontal plane where the fifth left driven pulley 309 and the fifth right driven pulley 310 are located and the horizontal plane where the sixth left driven pulley 311 and the sixth right driven pulley 312 are located; the axes of the second left driven pulley 303 and the second right driven pulley 304 are symmetrical about the reference axis, and the horizontal plane where the second left driven pulley 303 and the second right driven pulley 304 are located is located between the horizontal plane where the fifth left driven pulley 309 and the sixth right driven pulley 310 are located. The fifth right driven pulley 310 is located above the horizontal plane; the third left driven pulley 305 and the third right driven pulley 306 are symmetrical about the reference axis, and the horizontal plane where the third left driven pulley 305 and the third right driven pulley 306 are located is located above the horizontal plane where the second left driven pulley 303 and the second right driven pulley 304 are located; the fourth left driven pulley 307 and the fourth right driven pulley 308 are symmetrical about the reference axis, and the horizontal plane where the fourth left driven pulley 307 and the fourth right driven pulley 308 are located is located above the horizontal plane where the second left driven pulley 303 and the second right driven pulley 304 are located. The horizontal plane containing pulley 303 and the second right driven pulley 304 is between the horizontal plane containing the fifth left driven pulley 309 and the fifth right driven pulley 310; wherein, the distance between the first left driven pulley 301 and the first right driven pulley 302 and the reference shaft plane is greater than the distance between the sixth left driven pulley 311 and the sixth right driven pulley 312 and the reference shaft plane, and the distance between the third left driven pulley 305 and the third right driven pulley 306 and the reference shaft plane is less than the distance between the fifth left driven pulley 309 and the fifth right driven pulley 310. The distance between the driven pulley 310 and the reference shaft surface; the axes of the third left driven pulley 305 and the fourth left driven pulley 307 are located on the same vertical plane; the axes of the third right driven pulley 306 and the fourth right driven pulley 308 are located on the same vertical plane; the left drive arm 110 is provided with space for accommodating the rotor 810 between the third left driven pulley 305 and the fourth left driven pulley 307, and the right drive arm 120 is provided with space between the third right driven pulley 306 and the fourth right driven pulley 308.

[0047] like Figure 5 As shown, after the belt 400 exits from the driving pulley 610, it successively passes around the right side of the sixth left driven pulley 311, the left side of the first left driven pulley 301, the left side of the second left driven pulley 303, the upper side of the third left driven pulley 305, the right side of the fourth left driven pulley 307, the left side of the fifth left driven pulley 309, the right side of the fifth right driven pulley 310, the left side of the fourth right driven pulley 308, the upper side of the third right driven pulley 306, the right side of the second right driven pulley 304, the right side of the first right driven pulley 302, and the left side of the sixth right driven pulley 312, and finally returns to the driving pulley 610 to form a closed loop.

[0048] In this embodiment, a drive device for a rotor balancing machine for a new energy vehicle motor is used. When the device is running, the cylinder 660 drives the synchronous left drive arm 110 and right drive arm 120 to move in opposite directions through two claws 670 to control the belt 400 between the third left driven pulley 305 and the fourth left driven pulley 307, and between the third right driven pulley 306 and the fourth right driven pulley 308 to adhere to the surface of the rotor 810. That is, the wrap angle of the belt 400 on the rotor 810 consists of two parts, left and right, and the total wrap angle is large, which increases the limit value of the friction force of the belt 400 on the rotor 810, reduces the possibility of the belt 400 slipping on the rotor 810, and the resultant force vector of the force of the belt 400 on the rotor 810 is zero, which will not cause additional measurement errors.

[0049] Simultaneously, during the movement of the left drive arm 110 and right drive arm 120 driving the belt 400 to contact the rotor 810, the distance between the fifth left driven pulley 309 and the fourth left driven pulley 307, and the fifth right driven pulley 310 and the fourth right driven pulley 308 decreases, while the distance between the first left driven pulley 301 and the sixth left driven pulley 311, and the first right driven pulley 302 and the sixth right driven pulley 312 increases. The overall effect keeps the tension of the belt 400 constant. Then, the rotation drive assembly drives the drive pulley 610 to rotate, thereby driving the rotor 810 to rotate through the belt 400. The torque of the drive pulley 610 is transmitted to the surface of the rotor 810 through the belt 400, driving the rotor 810 to reach the speed required for measurement, thereby measuring the imbalance.

[0050] It is understandable that the structure of the pulley assembly is not limited to the one mentioned above. For example, an additional transition pulley may be set between the second left driven pulley 303 and the third left driven pulley 305, and between the second right driven pulley 304 and the third right driven pulley 306, depending on the actual situation. Alternatively, the second left driven pulley 303 and the second right driven pulley 304 may be eliminated, as long as the tension of the belt 400 remains unchanged during the synchronous opposite movement of the left drive arm 110 and the right drive arm 120.

[0051] In a preferred embodiment, such as Figure 1 , Figure 2 As shown, the rotation drive assembly includes a motor frame 630 fixedly mounted on the end face of the base 500 away from the left drive arm 110 and the right drive arm 120. The drive motor 640 is fixed on the motor frame 630 by a mounting plate 620, and the drive pulley 610 is poweredly connected to the drive motor 640.

[0052] It is understood that the structure of the rotation drive assembly is not limited to the one mentioned above. For example, a multi-stage transmission mechanism can be set between the drive motor 640 and the drive pulley 610, as long as it can achieve the rotation drive of the drive pulley 610.

[0053] In a preferred embodiment, such as Figure 2 , Figure 3 As shown, at least one travel groove 750 is provided through the adjusting block 740. A positioning bolt 760 that is threadedly connected to the connecting plate 730 is slidably provided in the travel groove 750. The sliding direction of the positioning bolt 760 in the travel groove 750 is the moving direction of the left drive arm 110 and the right drive arm 120. When the positioning bolt 760 is in the loose state, the adjusting block 740 can move relative to the positioning bolt 760, thereby driving the left drive arm 110 and the right drive arm 120 to move relative to the connecting plate 730, thereby realizing the distance adjustment between the left drive arm 110 and the right drive arm 120.

[0054] Before the equipment is put into operation, the installation positions of the two adjusting blocks 740 on the connecting plate 730 are adjusted according to the outer diameter of the rotor 810 and the tension required to drive the rotor 810, thereby adjusting the positions of the left drive arm 110 and the right drive arm 120 to suit rotors 810 with different outer diameters and meet the tension requirements of the belt 400. When the positioning bolt 760 is rotated and locked, the position of the adjusting block 740 relative to the connecting plate 730 is fixed, that is, the positions of the left drive arm 110 and the right drive arm 120 relative to the connecting plate 730 are re-fixed.

[0055] In a preferred embodiment, such as Figure 2 As shown, an adjustment groove 121 is provided on the right drive arm 120 at the position corresponding to the first right driven pulley 302. The first right driven pulley 302 is connected to the right drive arm 120 by a bearing stop pin and a fastening nut. The bearing stop pin can slide horizontally in the adjustment groove 121. When the bearing stop pin and the fastening nut are in the loose state, the first right driven pulley 302 can move horizontally to adjust the distance between itself and the reference shaft surface. When the fastening nut is in the tightened state, the position of the first right driven pulley 302 on the right drive arm 120 will be fixed.

[0056] In this embodiment, the drive device for a rotor balancing machine for a new energy vehicle motor described above is used. By adjusting the distance between the first right driven pulley 302 and the reference shaft surface, the tension of the belt 400 can be adjusted while the belt 400 is in contact with the rotor 810. This eliminates the need for secondary adjustment of the relative positions of the left drive arm 110, the right drive arm 120 and the slider 720, thereby improving detection efficiency.

[0057] Understandably, any driven pulley can be configured as an adjustable structure, as long as the overall tension of the belt 400 is kept balanced.

[0058] like Figures 6-10As shown in the figure, this application embodiment provides a support mechanism for a rotor balancing machine for a new energy vehicle motor, including a support frame 910, an adjustment frame 940, a positioning frame 920 for supporting the rotor 810, and a connecting rod 950 for connecting the support frame 910 and the adjustment frame 940. The support frame 910 has a support cavity 911 for accommodating the adjustment frame 940. The upper end of the adjustment frame 940 protrudes to the upper side of the support frame 910. The adjustment frame 940 has an upward-opening accommodating cavity 941 for accommodating the positioning frame 920. The positioning frame 920 can slide within the accommodating cavity 941. A connecting rod 930 is provided between the bottom of the positioning frame 920 and the bottom wall of the accommodating cavity 941. By rotating the connecting rod 930, the positioning frame 920 can be moved within the accommodating cavity 941 to adjust its height.

[0059] Two first mounting slots 912 are vertically connected between the inner wall of the support cavity 911 and the outer surface of the support frame 910. The two first mounting slots 912 are symmetrical about the positioning frame 920. Two second mounting slots 943 are vertically connected about the corresponding positions of the two first mounting slots 912 on the adjustment frame 940. The connecting rod 950 has two connecting rods and connects the first mounting slot 912 and the second mounting slot 943 on the corresponding side respectively. One end of the connecting rod 950 is hinged in the first mounting slot 912 by the first hinge 960, and the other end is hinged in the second mounting slot 943 by the second hinge 970.

[0060] When measuring the imbalance of rotor 810, a support structure is required to support rotor 810. In the existing soft support structure, according to Hooke's Law: F = k·x (F is the elastic force, k is the calibration coefficient, and x is the deformation), when the supported rotor 810 has a large mass or after a long period of use, the leaf spring undergoes plastic deformation, which also changes the calibration coefficient k. Therefore, after long-term use by the user, as the plastic deformation of the leaf spring increases, the leaf spring coefficient k also changes more when the leaf spring deformation x remains unchanged. Although the standard deviation of repeated measurements of the same rotor 810 on each single machine is relatively small, due to the different coefficients k, the measurement results F of the same rotor 810 on two or more soft support dynamic balancing machines using leaf springs will produce a considerable deviation, making it impossible for the user to confirm which machine's measurement result is accurate after measuring the same rotor 810 on multiple balancing machines.

[0061] In this embodiment, a support mechanism for a rotor balancing machine for a new energy vehicle motor is used. The support frame 910 and the adjustment frame 940 are respectively hinged at both ends of the connecting rod 950 to achieve the connection between the support frame 910 and the adjustment frame 940. Since the leaf spring type support structure will not only bend but also twist during operation, and the twisting deformation will increase the bending stiffness of the leaf spring, thus causing the characteristics of the support structure to deviate from the calibration data. In this embodiment, the connecting rod type support structure only undergoes rigid body motion (oscillation of the connecting rod mechanism) during operation. The characteristics of the support structure strictly conform to the calibration data. That is, the mechanical structural characteristics (i.e., dynamic friction coefficient) are used to replace the original leaf spring type soft support dynamic balancing machine. The soft support dynamic balancing machine is made using material mechanical properties, which solves the problem of inaccurate measurement results caused by plastic deformation of the leaf spring. This ensures that the equipment will not produce measurement data distortion even after long-term use, and also expands the load-bearing weight range of the same soft support balancing machine.

[0062] It is understandable that the connection structure between the connecting rod 950, the support frame 910, and the adjustment frame 940 is not limited to the one mentioned above. For example, the setting direction of the connecting rod 950 can be changed, that is, from vertical setting to various angle settings, as long as the connecting rods 950 on both sides are symmetrical about the positioning frame 920.

[0063] In a preferred embodiment, one end of the connecting rod 930 is rotatably connected to the adjusting frame 940 and the other end is threadedly connected to the positioning frame 920. When the connecting rod 930 rotates, the positioning frame 920 is restricted from rotating by the inner wall of the accommodating cavity 941, and thus moves within the accommodating cavity 941 by the thread to adjust the height.

[0064] It is understood that the connection structure of the connecting rod 930 is not limited to the one mentioned above. As long as the height of the positioning frame 920 can be adjusted, it is acceptable. For example, one end of the connecting rod 930 can be rotatably connected to the positioning frame 920 and the other end can be threadedly connected to the adjustment frame 940. In this case, the height of the positioning frame 920 can also be adjusted.

[0065] In a preferred embodiment, such as Figures 5-8 , Figure 10 As shown, the positioning frame 920 is symmetrically and rotatably provided with two positioning wheels 980 about the two first mounting slots 912. The two positioning wheels 980 are located at the top of the positioning frame 920. During use, the two support mechanisms are arranged opposite to each other, and the two ends of the rotor shaft 811 are respectively placed between the two positioning wheels 980 of the two support mechanisms, thereby realizing the positioning and support of the rotor 810 by the positioning frame 920. When the rotor 810 rotates, the shaft 811 and the two positioning wheels 980 on the corresponding side rotate relative to each other.

[0066] Understandably, the diameters of the two positioning rollers 980 on the positioning frame 920 and the distance between them are set according to the diameter of the rotating shaft 811, thereby ensuring stable support for the rotor 810. If necessary, the number of positioning rollers 980 can be increased to achieve full support for the rotating shaft 811.

[0067] In a preferred embodiment, such as Figures 5-8 , Figure 10 As shown, the adjustment frame 940 is provided with a through groove 942 located below the accommodating cavity 941. The through groove 942 is used to reduce the weight of the adjustment frame 940.
