Description

Technical Field

[0001] The present application relates to the technical field of automobile electric drive cover plates, and in particular to an automatic press-fitting device for automobile electric drive cover plate pins. Background Art

[0002] The automotive electric drive cover is a protective shell covering the electric vehicle drive system (such as the motor, controller, etc.). It mainly plays the role of protection, heat dissipation and isolation from external interference, ensuring that the drive system can operate stably in a complex and changeable driving environment.

[0003] The electric drive cover and its corresponding cover body are assembled to protect the motor, controller, and other components. To facilitate the secure connection between the two, several pins and bushings need to be pre-installed on the cover. However, these pins and bushings are currently assembled manually, resulting in low efficiency and unsuitable for mass production. Summary of the Invention

[0004] In order to achieve the simultaneous installation of multiple pins and bushings on the electric drive cover and improve production efficiency, the present application provides an automatic press-fitting device for automobile electric drive cover pins.

[0005] The present application provides an automatic press-fitting device for electric drive cover pins for automobiles, which adopts the following technical solutions: An automatic press-fitting device for pins of an electric drive cover plate of an automobile comprises a working platform provided with a positioning plate for positioning the electric drive cover plate, a feeding mechanism for driving the positioning plate to slide, a limiting mechanism provided on one side of the feeding mechanism and used to limit the sliding of the positioning plate, a pressing mechanism for pressing the electric drive cover plate, and an assembly mechanism; The assembly mechanism includes a plurality of first assembly mechanisms for assembling pins and a second assembly mechanism for assembling bushings.

[0006] By adopting the above technical solution, when the above automatic assembly device is used, the pins and bushings are pre-installed on the first assembly mechanism and the second assembly mechanism respectively, and then the electric drive cover plate is placed on the positioning plate to achieve preliminary positioning, and then the feeding mechanism is started to drive the positioning plate to move toward the clamping mechanism, and the positioning plate is limited and fixed in the horizontal and height directions by the limiting mechanism and the clamping mechanism to ensure stability during assembly, and finally the simultaneous installation of multiple pins and bushings is achieved through the assembly mechanism. The above structure realizes the automatic assembly of the electric drive cover plate, pins and bushings, with high assembly accuracy and efficiency, thereby improving production efficiency.

[0007] Optionally, the positioning plate is provided with a positioning block that abuts against the side wall of the electric drive cover plate, and positioning rings are provided at both ends of the electric drive cover plate. The positioning plate is provided with positioning pins that are plugged into the positioning rings.

[0008] By adopting the above technical solution, the provision of the positioning block and the positioning ring can play a positioning effect on the placement of the electric drive cover plate, ensure the stability of the electric drive cover plate during assembly, and improve the assembly accuracy of the pins.

[0009] Optionally, the loading mechanism includes a linear drive slide, a loading slide connected to the linear drive slide, and guide slides arranged on both sides of the loading slide, and the positioning plate and the loading slide are fixedly connected.

[0010] By adopting the above technical solution, the structural composition of the feeding mechanism is disclosed. The starting position of the feeding slide is away from one side of the clamping mechanism. After the electric drive cover is positioned, the linear drive slide is started to drive the feeding slide to move horizontally. The above-mentioned feeding mechanism has a compact structure, is easy to assemble, and has ideal stability.

[0011] Optionally, the limiting mechanism includes a limiting seat arranged on the side of the guide slide rail away from the linear drive slide rail, a limiting driving component arranged on the limiting seat, and a limiting plug connected to the output end of the limiting driving component. The side wall of the loading slide is provided with a limiting slot for inserting the limiting plug.

[0012] By adopting the above technical solution, when the feeding slide moves to the clamping side, the limit drive component is first started so that the limit plug is inserted into the limit slot. Through the cooperation of the limit plug and the limit slot, the horizontal direction of the feeding slide is limited. The plug-in method has a simple structure and relatively ideal stability.

[0013] Optionally, the two opposite side walls of the limiting plug along the insertion direction are provided with guiding inclined surfaces, and the inner wall of the limiting slot has a matching inclined surface that matches the guiding inclined surfaces.

[0014] By adopting the above technical solution, the setting of the guiding bevel and the matching bevel makes the inner wall of the limit block and the limit slot be beveled and matched, which helps to improve the insertion efficiency of the limit block compared to the use of straight surface abutment. At the same time, the matching of the bevel can form a locking effect, making the connection between the limit block and the limit slot tighter.

[0015] Optionally, the clamping mechanism includes a clamping fixed plate arranged on the top of the limiting mechanism, a clamping lifting plate installed to be lifted at the bottom of the clamping fixed plate, and a clamping driving member for driving the clamping lifting plate to be lifted; The pressing and fixing plate is provided with a balancing assembly, which includes synchronous lifting seats respectively provided on the pressing and fixing plate and a balancing connecting rod connecting adjacent synchronous lifting seats, and the screw ends of the synchronous lifting seats are fixed to the pressing and lifting plate; The bottom of the compression lifting plate is provided with an abutment assembly for abutting the electric drive cover plate. The abutment assembly includes a fixed abutment rod and an elastic abutment rod. The fixed abutment rod abuts at both ends of the electric drive cover plate in the length direction, and the elastic abutment rod is arranged at intervals along the outer edge of the electric drive cover plate.

[0016] By adopting the above technical solution, the structural composition of the clamping mechanism is disclosed. When the loading slide achieves horizontal limit, the clamping drive component is started to move the clamping lifting plate toward the top of the electric drive cover plate, and the abutment component is pressed on the electric drive cover plate to achieve vertical limit. Through the setting of the balancing component, the horizontality of the clamping lifting plate can be guaranteed. At the same time, under the action of the elastic abutment rod, it can adapt to the clamping of different heights of the top surface of the electric drive cover plate.

[0017] Optionally, the first assembly mechanism includes a first driving member provided on the working platform, a first assembly set pushed by the first driving member, and a pushing rod slidably mounted on the first assembly set, wherein the first assembly set has a first placement groove for arranging a pin; The second assembly mechanism includes a second driving member arranged on the working platform, a second assembly set pushed by the second driving member, and a pushing rod slidably installed on the second assembly set, and the second assembly set has a second placement groove for arranging a bushing.

[0018] By adopting the above technical solution, the structural composition of the first assembly mechanism and the second assembly mechanism is disclosed. When the electric drive cover completes the horizontal and vertical limiting, the first push drive member and the second drive member are started at the same time, so that the pin and the bushing are assembled to the electric drive cover at the same time, and the installation efficiency is high.

[0019] Optionally, pressure sensors are provided on the output shafts of the first push driving member and the second push driving member, and the output ends of the pressure sensors correspond to the ends of the push rods.

[0020] By adopting the above technical solution, the setting of the pressure sensor can detect the thrust of the driving member. When the thrust is greater than or less than the thrust standard value, an abnormal signal is generated to remind the staff to ensure the product yield.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The present invention relates to an automatic assembly device for automobile drive plate pins, comprising a work platform, a positioning plate, a loading mechanism, a limiting mechanism, a clamping mechanism, and an assembly mechanism. This combination of mechanisms enables automated assembly of electric drive cover plates, pins, and bushings, significantly improving assembly efficiency and reducing labor costs. 2. This application ensures the horizontality of the compression lift plate by setting a balancing component. At the same time, under the action of the elastic abutment rod, it can adapt to the compression of the top surface of the electric drive cover at different heights. 3. This application can detect the thrust of the driving member through the setting of the pressure sensor. When the thrust is greater than or less than the thrust standard value, a signal is sent to remind the staff to ensure the product yield. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is combined with Figure 1-8 This application is described in further detail.

[0033] The embodiment of the present application discloses an automatic press-fitting device for pins of an automobile electric drive cover.

[0034] Reference Figure 1 and Figure 2An automatic press-fitting device for automobile electric drive cover pins is used for automatic assembly of an electric drive cover 1, pins, and bushings. The device comprises a working platform 2 on which a positioning plate 3, a feeding mechanism 4, a limiting mechanism 5, a pressing mechanism 6, and an assembly mechanism are provided.

[0035] The electric drive cover plate 1 is an elongated cover body as a whole, and is provided with a plurality of first assembly grooves 11 for inserting pins and a plurality of second assembly grooves 12 for inserting bushings. In this embodiment, the electric drive cover plate 1 has six first assembly grooves 11 and two second assembly grooves 12. One of the first assembly grooves 11 is located at one end of the length direction of the electric drive cover plate 1 and is arranged in the vertical direction, and the remaining five first assembly grooves 11 are located at the other end of the length direction of the electric drive cover plate 1. Four of the five first assembly grooves 11 are arranged in the vertical direction, and the remaining first assembly groove 11 is arranged in the horizontal direction. The two second assembly grooves 12 are respectively located at both ends of the length direction of the electric drive cover plate 1.

[0036] Reference Figure 3 The positioning plate 3 is a rectangular plate, and a positioning block 31 for limiting the electric drive cover plate 1 and a positioning ring 32 for fitting with the electric drive cover plate 1 are provided on the top thereof. The positioning blocks 31 are located at both ends of the length direction of the electric drive cover plate 1, and the positioning blocks 31 have positioning grooves adapted to the outer protrusions of the electric drive cover plate 1. Positioning pins 13 that fit with the positioning ring 32 are provided at both ends of the length direction of the electric drive cover plate 1. Under the action of the positioning ring 32 and the positioning block 31, the electric drive cover plate 1 is initially positioned on the positioning plate 3. In this embodiment, the electric drive cover plate 1 is loaded onto the positioning plate 3 by an automatic clamping device such as a robot.

[0037] The loading mechanism 4 includes a linear drive rail 41 provided on the working platform 2, a loading slide 42 connected to the linear drive rail 41, and guide rails 43 provided on both sides of the linear drive rail 41. The linear drive rail 41 is a motor linear rail in the prior art. The loading slide 42 is fixedly connected to the slider on the linear drive rail 41. The guide rails 43 are provided parallel to both sides of the linear drive rail 41 to improve the sliding stability of the loading slide 42. The working platform 2 is also provided with buffers 21 at both ends of the guide rails 43. A buffer abutment block 421 is fixed to the bottom of the loading slide 42 for the buffer 21 to abut. The buffer 21 is used to absorb the impact force when the loading slide 42 stops, improve the conveying stability, and protect the linear drive rail 41.

[0038] Reference Figure 4The limiting mechanism 5 is used to restrict the horizontal movement of the loading slide 42 and is provided in correspondence with the clamping mechanism 6. The limiting mechanism 5 comprises a limiting seat 51 disposed on the side of the guide rail 43 away from the linear drive rail 41, a limiting driver 52 fixed to the limiting seat 51, and a limiting insert 53 connected to the output shaft of the limiting driver 52. In this embodiment, two sets of limiting mechanisms 5 are installed on the work platform 2, and the two sets of limiting mechanisms 5 are provided in correspondence with each other.

[0039] The limit seat 51 is an L-shaped support bolted to the work platform 2. The limit driver 52 is a push cylinder, whose piston rod extends through the sidewalls of the limit seat 51 and engages with the limit insert 53. Insertion seats 422 are fixedly mounted on both sides of the loading slide 42. These insert seats 422 have limit slots 4221 for the limit inserts 53. The cooperation between the limit inserts 53 and the limit slots 4221 achieves horizontal positioning of the loading slide 42. The opposing side walls of the limit insert 53 are also provided with guide slopes 531, which gradually approach each other along the insertion direction of the limit insert 53.

[0040] The plug seat 422 is provided with a matching bevel 4222 on the inner wall of the limiting slot 4221, which cooperates with the guide bevel 531. When the limiting plug 53 is inserted into the limiting slot 4221, the insertion efficiency of the limiting plug 53 is improved under the action of the guide bevel 531. As the limiting plug 53 is inserted, the guide bevel 531 and the matching bevel 4222 gradually fit together.

[0041] Reference Figure 5 and Figure 6 The clamping mechanism 6 is located above the limiting mechanism 5 and is used to limit the vertical position of the electric drive cover 1. The clamping mechanism 6 includes a clamping fixing plate 61, a clamping lifting plate 62, a clamping driving member 63 and a balancing assembly 64.

[0042] The clamping plate 61 is secured above the limiting mechanism 5 via four sets of fixed rods. A clamping and lifting plate 62 is mounted below the clamping and lifting plate 61 for lifting. The clamping and lifting plate 62 features guide sleeves 621 that fit over the fixed rods. Measuring assemblies 611 are mounted on both sides of the top of the clamping and lifting plate 61. These assemblies comprise two sets of measuring rods 6111 secured to the top of the clamping and lifting plate 62 and a connecting rod 6112 that connects the two sets of measuring rods 6111. The clamping and lifting plate 61 has through-holes for the measuring rods 6111 to pass through, and the measuring rods 6111 are marked with distance scales along their lengths.

[0043] The pressing driving member 63 is an electric cylinder fixed to the top of the pressing fixing plate 61 , which is vertically installed on the pressing fixing plate 61 . The output shaft of the pressing driving member 63 passes through the pressing fixing plate 61 and is fixedly connected to the pressing lifting plate 62 .

[0044] The balancing assembly 64 is mounted on the outer edge of the clamping plate 61 to ensure horizontal movement of the clamping and lifting plate 62. The balancing assembly 64 comprises four sets of synchronous lifting seats 641 and balancing connecting rods 642 that connect adjacent synchronous lifting seats 641. The synchronous lifting seats 641 consist of synchronous seats fixed to the clamping and fixing plate 61 and lifting gear rods extending vertically through the synchronous seats. The sidewalls of the lifting gear rods are provided with toothed surfaces along their length, and the bottom end of the lifting gear rods is flange-mounted to the clamping and lifting plate 62.

[0045] The bottom of the pressing lifting plate 62 is provided with a pressing lower template 622, and an abutting assembly for abutting the electric drive cover plate 1 is fixed on the pressing lower template 622. The abutting assembly includes a number of fixed abutting rods 623 and elastic abutting rods 624. The fixed abutting rods 623 are rigid abutments, which correspond to the two ends of the length direction of the electric drive cover plate 1. A number of elastic abutting rods 624 are evenly spaced along the outer edge of the electric drive cover plate 1. The elastic abutting rods 624 include an abutting seat, an elastic rod slidably mounted on the abutting seat, and an elastic reset member sleeved on the elastic rod. The elastic reset member is a rectangular spring. By fixing the abutting rods 623 and the elastic abutting rods 624, it can be ensured that the pressing mechanism 6 can achieve a pressing effect on the concave and convex top surface of the electric drive cover plate 1.

[0046] The assembly mechanism includes six sets of first assembly mechanisms 7 for pin assembly and two sets of second assembly mechanisms 8 for bushing assembly. The number of the first assembly mechanisms 7 and the second assembly mechanisms 8 is consistent with the number of the first assembly slots 11 and the second assembly slots 12.

[0047] Reference Figure 7 and Figure 8 The first assembly mechanism 7 includes a first driving member 71 disposed on the work platform 2, a first assembly member 72 for being driven by the first driving member 71, and a first driving rod 73 slidably mounted on the first assembly member 72. In this embodiment, five sets of the first driving members 71 are vertically fixed to the work platform 2, and the remaining set of the first driving members 71 is horizontally fixed to the work platform 2 via a bracket.

[0048] The first assembly sleeve 72 is fixed to the positioning plate 3 and contains a sliding chamber 721 for the sliding arrangement of the first push rod 73. The two ends of the sliding chamber 721 extend through the upper and lower end surfaces of the first assembly sleeve 72. Before assembly, the bottom end of the first push rod 73 passes through the bottom opening of the sliding chamber 721 under the action of gravity. A first placement slot 722 for the pin is formed between the top of the first push rod 73 and the top opening of the sliding chamber 721. The inner diameter of the first placement slot 722 matches the outer diameter of the pin.

[0049] The second assembly mechanism 8 includes a second driving member 81 disposed on the work platform 2, a second assembly sleeve 82 for being driven by the second driving member 81, and a second push rod 83 slidably mounted on the second assembly sleeve 82. The second assembly sleeve 82 has the same structure as the first assembly sleeve 72 and has a second placement groove 821 for the bushing. The end of the second push rod 83 has a push portion 831 that fits snugly around the bushing.

[0050] The first and second driving members 71, 81 are both hydraulic cylinders, each equipped with a pressure sensor 74 at its output end to monitor the pressure applied by the driving member to the push rod. The pressure value during normal assembly of the pin and bushing is defined as the baseline pressure, while the pressure value applied by the driving member to the pin or bushing during actual operation is defined as the actual pressure. When the pressure sensor 74 detects that the actual pressure is greater than or less than the baseline pressure, an alarm is generated, prompting the operator to check the corresponding position on the electric drive cover 1.

[0051] The implementation principle of the automatic press-fitting device for the pin of the automobile electric drive cover plate of the present application is as follows: the pin and the bushing are respectively placed in the first assembly groove 11 and the second assembly groove 12 of the positioning plate 3 in advance, and then the electric drive cover plate 1 is placed on the positioning plate 3 by a manipulator or a lifting device, and the positioning block 31 and the positioning ring 32 are used to perform preliminary positioning of the electric drive cover plate 1; Start the linear drive slide 41 to move the electric drive cover plate 1 to the bottom of the clamping mechanism 6. The feeding slide plate 42 is limited in the horizontal direction by the limiting mechanism 5, and the electric drive cover plate 1 is limited in the vertical direction by the clamping mechanism 6. The first assembly mechanism 7 and the second assembly mechanism 8 are started simultaneously to insert the six groups of pins and the two groups of bushings into the electric drive cover 1 at the same time.

[0052] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
