Description

Technical Field

[0001] The invention relates to the technical field of motor assembly structures, and in particular to a motor end cover assembly assembly device. Background Art

[0002] The motor assembly structure is a mechanical device used to assemble the various parts of the motor. Its main function is to ensure that the core components of the motor, such as the front cover, rear cover, rotor and stator, can be installed in a predetermined order. In the conventional motor assembly structure, the rear cover of the motor usually relies on mechanical fixtures and positioning mechanisms to complete the fixation and positioning. For example, the motor housing is placed in a groove in a mechanical fixture, and subsequent assembly can be carried out. In the standard assembly process, its high repeatability and stability can meet the production requirements of ordinary motors.

[0003] However, when faced with high-precision motor assembly tasks, simply placing the motor housing into the groove is difficult to meet the motor production requirements. Additional workstations are required to place mechanical fixtures and positioning mechanisms. For example, additional mechanical fixtures and positioning mechanisms are required to adjust the angle of the motor housing (exemplarily, a rotary clamping cylinder is set at an additional workstation, and the rotary clamping cylinder is used to clamp the motor housing and rotate its angle), thereby improving the subsequent positioning accuracy between the motor housing and the rear end cover. It can be seen that for the above-mentioned motor assembly structure, the higher the assembly accuracy of the motor, the more workstations it requires, resulting in a larger footprint for the overall motor assembly structure, which in turn leads to higher site costs.

[0004] Therefore, how to ensure the assembly accuracy of the motor while reducing the floor space occupied by the motor assembly structure is a technical problem that needs to be urgently solved in the art. Summary of the invention

DETAILED DESCRIPTION

[0050] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0052] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0053] The motor end cover assembly assembly equipment provided by the present invention is suitable for the scenario of assembling a motor housing 001 and a motor end cover 002. It can use fasteners such as rivets and pins to complete the connection between the motor housing 001 and the motor end cover 002. In this embodiment, by improving the structure of the motor end cover assembly equipment, the angles of the motor housing 001 and the motor end cover 002 can be adjusted as required, thereby meeting the assembly accuracy requirements and reducing the overall footprint.

[0054] In this embodiment, the motor housing 001 mainly refers to the rear end cover of the motor. The rear end cover of the motor in this embodiment is provided with a plurality of motor assembly holes 0011 spaced along the circumferential direction. The motor assembly holes 0011 can be used for connecting parts to pass through the rear end cover and the front end cover of the motor to complete the front and rear connection of the motor.

[0055] like Figures 1 to 5 As shown, the motor end cover assembly assembly equipment in this embodiment includes a turntable assembly 100 and a shell loading assembly 200, an end cover loading assembly 300 and an assembly assembly 400 which are sequentially arranged around the turntable assembly 100. The shell loading assembly 200 is used to place the motor shell 001 on the turntable assembly 100, and the motor shell 001 is provided with a motor assembly hole 0011; the shell loading assembly 200 includes a rotating cylinder and a clamping motor installed at the rotating end of the rotating cylinder, and the motor shell 001 can be clamped by the clamping motor, and the motor shell 001 can be transferred by cooperating with the rotating cylinder, which is not limited in this embodiment, and the motor shell 001 can be moved; similarly, the end cover loading assembly 300 may include a rotating cylinder and a clamping motor installed at the rotating end of the rotating cylinder, and may also include other posture adjustment structures such as a manipulator, which can move the motor end cover 002, which is not limited in this embodiment; the assembly assembly 400 is used to connect the motor shell 001 and the motor end cover 002 with fasteners.

[0056] like Figures 2 to 8 As shown, a housing positioning hole 101 is provided on the turntable assembly 100, and the housing positioning hole 101 is used to place the motor housing 001; a positioning and rotating assembly 500 is installed at a position of the turntable assembly 100 corresponding to the housing positioning hole 101; the positioning and rotating assembly 500 includes a movable portion 510 which is arranged on one side of the housing positioning hole 101 and can move in a direction away from or close to the housing positioning hole 101, and the movable portion 510 includes a first positioning wheel 511 arranged close to the housing positioning hole 101; the positioning and rotating assembly 500 also includes a housing support portion 520 arranged below the housing positioning hole 101, and the housing support portion 520 includes a second positioning wheel 521 arranged toward the bottom wall of the motor housing 001; the first positioning wheel 511 can be driven to rotate to drive the motor housing 001 to rotate until the motor assembly hole 0011 is sleeved outside the second positioning wheel 521.

[0057] Specifically, when assembling the motor housing, the motor housing 001 is placed in the housing positioning hole 101 of the turntable assembly 100 through the housing loading assembly 200. As the turntable assembly 100 rotates, the motor housing 001 is driven to pass through the end cover loading assembly 300 and the assembly assembly 400 in sequence, so that the motor end cover 002 is placed on the motor housing 001, and the motor end cover 002 and the motor housing 001 are fastened using the assembly assembly 400. Among them, the motor housing 001 is placed in the housing positioning hole 101 in the housing loading component 200. If the motor assembly hole 0011 is misaligned with the second positioning wheel 521, the second positioning wheel 521 supports the motor housing 001, and the first positioning wheel 511 abuts against the side of the motor housing 001. Then, the driven rotating first positioning wheel 511 can be used to rotate the motor housing 001 until the motor assembly hole 001 is opposite to the second positioning wheel 521, so that the motor assembly hole 001 is sleeved outside the second positioning wheel 521, thereby completing the position calibration of the motor housing 001 without the need to reserve an additional work station, and realizing the adjustment of the angle of the motor housing 001. On the premise of meeting the motor assembly accuracy, the floor space required for the motor end cover assembly assembly equipment is reduced.

[0058] Furthermore, the motor housing 001 and the motor end cover 002 are coaxially arranged, and the outer edge of the motor end cover 002 is closer to the axis of the motor housing 001 than the motor assembly hole 0011 .

[0059] When the motor assembly hole 0011 and the second positioning wheel 521 are misaligned, the movable part 510 is pressed to leave a first spacing with the motor assembly hole 0011, and the first positioning wheel 511 abuts against the side wall of the motor housing 001; when the motor assembly hole 0011 and the second positioning wheel 521 are relatively arranged, the movable part 510 is pressed to leave a second spacing with the motor assembly hole 0011, and the first positioning wheel 511 abuts against the side wall of the motor end cover 002; the second spacing is smaller than the first spacing, and along the circumferential direction of the turntable assembly 100, an end cover angle detection assembly is also arranged between the end cover feeding assembly 300 and the assembly assembly 400. It should also be noted that after the motor housing 001 is placed in the motor assembly hole 0011, the position of the motor end cover 002 is flush with the first positioning wheel 511, but when the motor housing 001 is not placed in the motor assembly hole 0011 and is supported by the second positioning wheel 521, the position of the motor end cover 002 is higher than the first positioning wheel 511.

[0060] It is understandable that, because the size of the motor housing 001 is larger, when the housing positioning hole 101 and the motor assembly hole 0011 are not aligned, and the bottom surface of the motor housing 001 is supported by the second positioning wheel 521, the distance between the movable part 510 and the motor assembly hole 0011 is larger; once the housing positioning hole 101 and the motor assembly hole 0011 are aligned, the motor housing 001 partially falls into the housing positioning hole 101, and the second positioning wheel 521 enters into the motor assembly hole 0011, the position of the motor end cover 002 is flush with the first positioning wheel 511, which is convenient for cooperating with the end cover angle detection component to adjust the angle of the motor end cover 002, further reducing the floor space required for the motor end cover assembly equipment. Among them, the end cover angle detection component can be a visual detection solution such as CCD, binocular vision, etc., which can identify the angle of the motor end cover 002 so that the positioning rotation component 500 can adjust its angle. The end cover angle detection component can be suspended on one side of the end cover feeding component 300, and can also be suspended on one side of the assembly component 400, which is conducive to a more compact overall layout.

[0061] Furthermore, if Figures 1 to 8 As shown, the movable part 510 is installed on the upper surface of the turntable assembly 100 through the upper positioning seat 530; the upper positioning seat 530 is provided with a horizontal slide groove 531, and the movable part 510 is slidably connected to the horizontal slide groove 531; the movable part 510 is provided with a first synchronous wheel 5121 and a second synchronous wheel 5122, and the first synchronous wheel 5121 and the second synchronous wheel 5122 are provided with a synchronous belt 5123 on their outer sleeves; the first synchronous wheel 5121 is coaxially fixedly connected to the first positioning wheel 511; the upper positioning seat 530 is also fixedly connected to the positioning rotating motor 513, and the motor shaft of the positioning rotating motor 513 is fixedly connected to the third synchronous wheel 514, which is located between the first synchronous wheel 5121 and the second synchronous wheel 5122 and meshes with an inner wall of the synchronous belt 5123. Among them, the movable part 510 is provided with an avoidance slide groove corresponding to the connection between the third synchronous wheel 514 and the positioning rotating motor 513.

[0062] It can be understood that the movable part 510 is slidably connected through the horizontal slide groove 531 of the upper positioning seat 530, and the horizontal slide groove 531 provides a fixed sliding path, allowing the movable part 510 to move along this path when needed. After the first positioning wheel 511 is squeezed and pushed by the motor housing 001 or the motor end cover 002, the movable part 510 is away from the housing positioning hole 101, and the relative position of the third synchronous wheel 514 and the synchronous belt 5123 changes. However, after the position is changed, the positioning rotation motor 513 can still be engaged with an inner wall of the synchronous belt 5123 through the third synchronous wheel 514, thereby driving the first synchronous wheel 5121 to rotate, and then driving the first synchronous wheel 5121 to operate coaxially with the fixedly connected first positioning wheel 511, ensuring that the first positioning wheel 511 can move closely following the rotation of the positioning rotation motor 513, and has the advantage of compact structure.

[0063] On the basis of the above-mentioned embodiment, a positioning block 515 is protrudingly provided at the end of the movable part 510 near the motor assembly hole 0011, and a spring mounting plate 532 is protrudingly provided at the position of the upper positioning seat 530 corresponding to the positioning block 515; a first compression spring (not shown) is installed between the positioning block 515 and the spring mounting plate 532; when the first compression spring is not compressed, the distance between the end of the movable part 510 and the motor assembly hole 0011 is smaller than the second distance between the movable part 510 and the motor assembly hole 0011 when the first positioning wheel 511 abuts against the side wall of the motor end cover 002. This ensures that the first positioning wheel 511 can always contact the motor housing 001 or the motor end cover 002.

[0064] In this embodiment, the end face of the positioning block 515 facing the motor assembly hole 0011 is a first inclined surface 5151, and the first inclined surface 5151 is used to be compressed and drive the movable part 510 to move in a direction away from the motor assembly hole 0011; two positioning blocks 515 arranged at intervals are protruded from the movable part 510, and the axis of the first positioning wheel 511 is located between the two positioning blocks 515, which can improve the stability of the movable part 510 under pressure and movement.

[0065] On the basis of the above-mentioned embodiment, the number of motor assembly holes 0011 is multiple, and they are arranged on the motor housing 001 at intervals with a circumferential distribution; the housing support portion 520 is installed on the lower surface of the turntable assembly 100 through the lower positioning seat 540, and the lower positioning seat 540 is provided with a lifting slot 541 corresponding to each second positioning wheel 521, and the second positioning wheel 521 is slidably connected to the lifting slot 541 through a lifting rod 542; an elastic unit is arranged between the lower positioning seat 540 and the lifting rod 542, and the elastic unit is used to make the second positioning wheel 521 have a movement direction away from the lower positioning seat 540.

[0066] Specifically, a lifting plate 543 is also arranged between the lower positioning seat 540 and the lower surface, and the lifting plate 543 is fixedly connected to the lifting rod 542; the elastic unit includes a second compression spring arranged between the lifting plate 543 and the lower positioning seat 540, one end of the second compression spring abuts against the lower positioning seat 540, and the other end of the second compression spring abuts against the lifting plate 543.

[0067] Based on the above implementation, Figures 8 to 11 As shown, the assembly component 400 includes a fastener feeding part 410 and a lifting part 420; the lifting end of the lifting part 420 is installed with a translation part 430 and a fastening stamping part 440, and is also installed with a first positioning member 461 for inserting into the motor assembly hole 0011 and a second positioning member 462 for squeezing the movable part 510 and inserting into the motor assembly hole 0011; the first positioning member 461 and the second positioning member 462 are arranged opposite to each other, and are provided with an arc positioning block 463 for positioning the motor end cover 002; the translation end of the translation part 430 is installed with a moving member 450, and the moving member 450 is provided with a moving hole, and the moving hole moves between the fastener feeding part 410 and the fastening stamping part 440 through the translation part 430.

[0068] The fastener feeding part 410 may include a vibrating screen, a guide pipe 411 installed on a frame, and other structures, which can put the fastener into the material transfer hole. The lifting part 420 includes a lifting cylinder 421, and a guide block 422 is installed at the lifting end of the lifting cylinder 421; the guide block 422 is provided with a guide groove 4221, and the end of the guide block 422 is formed with a second inclined surface 4222; the second inclined surface 4222 is used to squeeze the movable part 510 before the positioning part is inserted into the motor assembly hole 0011; the material transfer part 450 is slidably installed in the guide groove 4221. The translation part 430 and the fastening stamping part 440 can both use cylinders, or other power elements, which can provide kinetic energy for translation.

[0069] As a supplementary embodiment, an electromagnetic push rod 550 is also installed on the lower positioning seat 540, and a avoidance hole is opened at the position of the lifting plate 543 corresponding to the electromagnetic push rod 550; a first contact is arranged on the lifting plate 543, and a second contact is arranged at the position corresponding to the first contact on the lower positioning seat 540; when the positioning member is inserted into the motor assembly hole 0011 and pushes the second positioning wheel 521, the first contact is electrically connected to the second contact, and the push rod of the electromagnetic push rod 550 is pushed out to support the fastener. The two contacts can be conductive sheets or conductive needles made of metal, which are precisely positioned to ensure that they can contact each other to form electrical conduction under the above conditions. When the positioning member is inserted into the motor assembly hole 0011 and applies sufficient force to push the second positioning wheel 521, the lifting plate 543 is driven to move downward, so that the first contact fixed thereon drops to a position in contact with the second contact fixed on the lower positioning seat 540, similar to an electrical switch, completing the circuit closure. The closed contacts allow current to pass, and then this electrical signal is used to trigger the electromagnetic push rod member 550, so that its push rod is pushed out and supported under the assembly hole of the motor housing 001.

[0070] To facilitate the understanding of those skilled in the art, the working principle of the motor end cover assembly equipment is explained:

[0071] During the rotation of the turntable assembly 100, its housing positioning hole 101 moves to the housing loading assembly 200, and the structures such as the gripper motor of the housing loading assembly 200 grab a motor housing 001 to the top of the housing positioning hole 101, and at the same time, it also positions one side of the rotating assembly 500; at this time, if the housing positioning hole 101 and the motor assembly hole 0011 are not aligned, the bottom surface of the motor housing 001 is supported by the second positioning wheel 521, and the side surface of the manipulator motor housing 001 is abutted by the first positioning wheel 511, and the motor 513 is driven by the positioning rotation motor 513. The third synchronous wheel 514 rotates, and then drives the first synchronous wheel 5121 to rotate through the synchronous belt 5123, so as to drive the first positioning wheel 511 to rotate. At this time, the clamping jaw motor slightly loosens the motor housing 001 to provide support for the rotation of the motor housing 001, so that the motor housing 001 is driven by the first positioning wheel 511 to rotate, until the housing positioning hole 101 is aligned with the motor assembly hole 0011, and the motor housing 001 partially falls into the housing positioning hole 101, and the second positioning wheel 521 enters the motor assembly hole 0011, completing the turntable loading of the motor housing 001;

[0072] Next, the turntable assembly 100 continues to rotate, and its housing positioning hole 101 moves to the bottom of the end cover feeding assembly 300. The structures such as the clamping claw motor of the housing feeding assembly 200 cover a motor end cover 002 on the motor housing 001. During the covering process of the motor end cover 002, the motor end cover 002 will push open the movable part 510. Under the action of the first compression spring, it is ensured that the first positioning wheel 511 is in contact with the motor end cover 002. At this time, the clamping claw motor slightly loosens the motor end cover 002 to provide support for the rotation of the motor end cover 002. After the positioning rotation motor 513 drives the third synchronous wheel 514 to rotate, and then drives the first synchronous wheel 5121 to rotate through the synchronous belt 5123, so as to drive the first positioning wheel 511 to rotate, so as to drive the motor end cover 002 to rotate, and cooperate with the visual recognition device such as the CCD device to realize the positioning between the motor end cover 002 and the motor housing 001.

[0073] Next, the turntable assembly 100 continues to rotate, and its housing positioning hole 101 moves to the bottom of the assembly assembly 400. At this time, the fastener feeding part 410 conveys a fastener to the material moving part 450 through the material guide tube 411. The lifting end of the lifting cylinder 421 descends, and the material guide tube 411 installed on the frame is separated from the material moving part 450. At the same time, the second inclined surface 4222 abuts against the first inclined surface 5151, so that the first positioning member 461 and the second positioning member 462 are inserted into the corresponding motor assembly hole 0011. At this time, the arc positioning blocks 463 on both sides laterally fix the motor end cover 002 from both sides. The positioning member inserted into the motor assembly hole 0011 will push the second positioning wheel 521, thereby driving the lifting plate 543 to move downward through the lifting rod 542, so that the first contact and the second contact are in contact, thereby triggering the electromagnetic push rod 550, and the push rod of the electromagnetic push rod 550 rises, and the rising push rod is used to support the bottom of the mounting hole of the motor housing 001. Then, the translation cylinder of the translation part 430 is used to drive the material moving part 450 to move, so that the fastener is moved to the bottom of the fastening punching part 440, and then the fastener is pressed into the assembly hole of the motor end cover 002 and the motor housing 001 by the punching cylinder of the fastening punching part 440, so as to complete the assembly between the motor end cover 002 and the motor housing 001. The push rod as a support can prevent the fastener from leaking out of the motor housing 001, thereby improving the installation accuracy;

[0074] Finally, the turntable assembly 100 continues to rotate, and its housing positioning hole 101 moves to the bottom of the blanking assembly, so that the motor housing 001 assembled with the motor end cover 002 can be taken out.
