Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gasket assembly equipment for automobile parts, in particular to a mistake-proof device for installing a gear side clearance adjusting gasket of a reducer. BACKGROUND

[0002] The automobile rear drive axle reducer is a core component of the power transmission system, and its assembly quality directly affects the NVH performance, transmission efficiency and service life of the whole vehicle. Among them, the tooth side clearance adjustment of the driving bevel gear is a key process of the reducer assembly, and the precise adjustment is achieved by installing adjusting gaskets of different thicknesses.

[0003] On the existing assembly line, the thickness of the gasket to be installed is calculated by detection equipment, but the searching, grabbing and installing of the gasket are all completed manually by the operator. The adjusting gasket is mostly a metal sheet with very similar appearance, and only the thickness is distinguished. There are many thickness specifications, and in the high-paced and repetitive assembly line operation, the operator is prone to make mistakes due to visual fatigue and distraction, resulting in wrong taking and wrong installation. Once the installation is wrong, it is often impossible to discover immediately at the subsequent station, and the defect will flow into the final detection or further downstream.

[0004] With the continuous improvement of the production line rhythm, the speed and accuracy of manual searching, comparison, taking and placing of small gaskets have reached the limit, becoming a bottleneck restricting the improvement of overall assembly efficiency. At the same time, the trend of multi-variety and small-batch production requires the production line to be able to switch quickly, and manual methods cannot achieve accurate and efficient management of different specifications of gasket systems.

[0005] That is, the prior art has the following technical problems: the unreliability caused by the fact that ordinary gasket selection work is completed manually. Therefore, the mistake-proof device for installing the gear side clearance adjusting gasket of the reducer is proposed to solve the above problems. SUMMARY

[0046] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0047] Please see Figure 1 , Figure 2 and Figure 3As shown, the reducer tooth backlash adjustment shim installation error prevention device includes a shim feeding mechanism 4 and a shim gripping unit 5;

[0048] There are several gasket feeding mechanisms 4. All gasket feeding mechanisms 4 are fixedly installed on the frame 2 to form a parallel arrangement of gasket storage and output stations. Each station independently stores a single adjustment gasket 7 of a specific thickness.

[0049] A conveying component 3 is provided on the side of the gasket feeding mechanism 4. The conveying component 3 consists of an X-axis moving part, a Y-axis moving part and a Z-axis moving part. One end of the conveying component 3 is fixedly connected to a gasket gripping unit 5, which is used to receive instructions from the control system and move in three-dimensional space to grip the gasket 7 from the designated gasket feeding mechanism 4 and transport it to the preset gasket tray 6.

[0050] This application, through physically isolated independent silos, separate feeding mechanisms, and fully automated three-axis conveying structures, can completely replace manual handling of gaskets, eliminating the confusion of gaskets of different specifications from the source. This achieves a high degree of automation and precision in the assembly process, thereby significantly improving assembly quality and efficiency, reducing quality costs, and ensuring reliable operation. It is also particularly suitable for integration into high-speed automotive reducer assembly production lines.

[0051] In a preferred embodiment of this application, see [reference] Figure 2 and Figure 3 As shown, it also includes a support component 1, which includes a processing platform 101 and a support frame 102. The support frame 102 is fixedly installed at the bottom of the processing platform 101 to provide a stable installation foundation for the entire device. The frame 2 is fixedly connected to the upper surface of the processing platform 101. The conveying component 3 is fixedly installed on the upper surface of the processing platform 101. A pad tray 6 is also fixedly connected to one side of the upper surface of the processing platform 101.

[0052] Preferably, in order to meet the precision requirements of adjusting the backlash of the drive bevel gear of the rear axle reducer, and based on the statistical distribution of gear manufacturing errors, the number of shim feeding mechanisms 4 is 10, which are fixed on the frame 2 in two layers, upper and lower, to store ten different thicknesses of adjustment shims 7, so as to cover all the adjustment specifications required for assembly and achieve fine adjustment.

[0053] In one specific embodiment of this application, see [reference]. Figure 4As shown, the gasket feeding mechanism 4 includes a push rod guide plate 402, a push rod 408, and a hopper 406. A base plate 401 is fixedly connected to the bottom surface of the push rod guide plate 402. The base plate 401 is fixedly mounted on the frame 2, providing an installation reference and support for the entire gasket feeding mechanism 4. A gasket slide 5021 is provided inside the push rod guide plate 402. One end of the gasket slide 5021 is arc-shaped, used to guide and constrain the movement trajectory of the gasket 7, ensuring its smooth sliding. A circular hole 4011 is also provided at the front end of the base plate 401, which is the endpoint position after the gasket 7 is pushed out. A slidable push rod 408 is provided inside the gasket slide 5021. A hopper 406 is provided above the push rod guide plate 402, used for stacking and storing the gaskets 7. This technical solution constitutes a basic single-sheet gasket ejection mechanism. The action of the push rod 408 can push the bottommost single-sheet gasket 7 out from below the hopper 406.

[0054] Further, see Figure 5 As shown, a push rod mating seat 403 is fixedly connected to the upper surface of the push rod guide plate 402. A chute bottom plate 404 is fixedly connected to the upper surface of the push rod mating seat 403. A sliding plate 405 is fixedly connected to the bottom of the hopper 406. The sliding plate 405 and the chute bottom plate 404 slide together, allowing the hopper 406 to switch between the "feeding position" and the "locked position". Preferably, the side wall of the chute bottom plate 404 is also provided with spring beads 410 to provide a certain positioning friction after the hopper 406 slides into place, preventing it from accidentally shifting during handling or vibration. A feeding cylinder 407 is fixedly connected to one side of the bottom plate 401. One end of the feeding cylinder 407 is fixedly connected to the push rod 408, providing power for the reciprocating linear motion of the push rod 408. Through this technical solution, convenient replacement and reliable locking of the hopper 406, as well as pneumatic drive for the pushing action, are achieved.

[0055] Preferably, to ensure that the push rod 408 pushes only one washer at a time and prevents multiple washers from being sent out simultaneously, the thickness of the push rod 408 is designed to be less than the thickness of a single washer 7. For example, when the washer thickness is 2.0 mm, the push rod thickness is 1.5 mm. Figure 6 As shown, the front end of the push rod 408 is provided with a V-shaped inclined surface 4081, which allows the two inclined surfaces to symmetrically contact the edge of the inner hole of the pad when pushing the pad. Utilizing the "two-point centering" principle, the center of the pad automatically coincides with the axis of the push rod. This technical solution effectively avoids the pad from tilting or jamming due to uneven force during the pushing process.

[0056] Preferably, to further ensure the reliability of single-sheet feeding and eliminate the risk of two shims being pushed out simultaneously, the thickness of the shim slide 5021 (i.e., the gap between the push rod guide plate 402 and the base plate 401) is designed to be greater than the thickness of a single shim 7 but less than the sum of the thicknesses of two shims 7. For example, for a shim with a thickness of 2.0 mm, the thickness of this channel can be set between 2.1 mm and 3.9 mm. Through this technical solution, the physical structure ensures that only a single shim is allowed to pass through, achieving rigid error prevention.

[0057] Furthermore, to enable the same gasket feeding mechanism 4 to adapt to gasket specifications with slightly different thicknesses that may appear in the future, and to enhance the versatility and adjustability of the equipment, refer to... Figure 8 As shown, a groove is provided below the push rod mating seat 403. A slidable stop 4091 is provided in the groove of the push rod mating seat 403 to form a slide thickness adjustment unit 409. This unit is used to adjust the effective passage height of the shim slide 5021 by changing the vertical position of the stop 4091. With this technical solution, new specification shims can be quickly adapted without replacing the entire push rod guide plate 402, thus improving the flexibility of the equipment.

[0058] For specific technical solutions, please refer to Figure 9 and Figure 10 As shown, the slide thickness adjustment unit 409 also includes an adjusting rod 4093, a threaded sleeve 4094, and an adjusting screw 4095. Guide rods 4092 are fixedly connected to both sides of the stop block 4091. The guide rods 4092 pass through the push rod mating seat 403 and slide with it, providing stable guidance for the stop block 4091. An adjusting rod 4093 is fixedly connected to the upper surface of the stop block 4091. The adjusting rod 4093 passes through the push rod mating seat 403 and slides with it. An inner cavity is provided inside the adjusting rod 4093. A threaded sleeve 4094 is fixedly connected to the inner cavity of the adjusting rod 4093. An adjusting screw 4095 is rotatably connected to the inner cavity of the push rod mating seat 403, and the adjusting screw 4095 passes through the threaded sleeve. 4094 is threadedly engaged with the threaded sleeve 4094. The side wall of the push rod mating seat 403 is also rotatably connected to the connecting rod 4098. One end of the connecting rod 4098 is fixedly connected to the first bevel gear 4096. The end of the adjusting screw 4095 is fixedly connected to the second bevel gear 4099 that meshes with the first bevel gear 4096. One end of the connecting rod 4098 is fixedly connected to the adjusting knob 4097. Through this technical solution, when the adjusting knob 4097 is rotated to drive the connecting rod 4098 to rotate, the bevel gear pair drives the adjusting screw 4095 to rotate. The rotation of the screw drives the threaded sleeve 4094 and the adjusting rod 4093 that are threadedly engaged with it to move up and down, thereby driving the stop block 4091 to rise and fall, and finally realizing the adjustment of the height of the gasket slide 5021.

[0059] In one specific embodiment of this application, see [reference]. Figure 11 As shown, the X-axis moving part of the conveying assembly 3 includes a guide rail 301 and a guide slide 302. The guide rail 301 is fixedly mounted on the upper surface of the support assembly 1. The guide slide 302 is slidably connected to the guide rail 301. A Z-axis moving part is fixed on the upper surface of the guide slide 302 to support its horizontal movement in the X direction. Synchronous pulleys 303 are rotatably connected to both sides of the guide rail 301. A synchronous belt 312 is sleeved between the two synchronous pulleys 303. One side of the synchronous belt 312 is fixedly connected to the guide slide 302. A drive motor 304 is also fixedly mounted on the upper surface of the support assembly 1. The output shaft end of the drive motor 304 is connected to the synchronous pulleys 303 via a coupling. Through this technical solution, the drive motor 304, through the transmission of the synchronous pulleys 303 and the synchronous belt 312, can precisely control the reciprocating linear motion of the guide slide 302 and the entire upper part along the X-axis direction, for quickly aligning ten different gasket feeding mechanisms 4.

[0060] Furthermore, the Z-axis moving part includes a lifting slider 307 and a screw 308. A support plate 305 is fixedly connected to the upper surface of the guide slide 302. One end of a vertical guide rod 306 is fixedly connected to the top of the support plate 305, and the other end of the vertical guide rod 306 is fixedly connected to the upper surface of the guide slide 302. This provides high-precision vertical guidance for the up-and-down movement of the lifting slider 307 and prevents it from swaying. The vertical guide rod 306 passes through the lifting slider 307 and is slidably engaged with it. A screw 308 is also rotatably connected between the support plate 305 and the guide slide 302. The screw 308 passes through the lifting slider 307 and is threadedly engaged with it. A control motor 309 is fixedly mounted on the top of the support plate 305, and the end of the output shaft of the control motor 309 is fixedly connected to the top of the screw 308. Through this technical solution, the control motor 309 drives the screw 308 to rotate, and converts the rotational motion into the precise linear lifting motion of the lifting slider 307 along the vertical guide rod 306, thereby driving the pad gripping unit 5 to achieve position adjustment in the Z-axis direction. Its transmission has self-locking properties and can reliably maintain its position when the power is off.

[0061] Furthermore, see Figure 11 As shown, the Y-axis moving part includes a support plate 310 and a control cylinder 311. The support plate 310 is fixedly mounted on the side wall of the lifting slider 307, and the control cylinder 311 is fixedly connected to the upper surface of the support plate 310. A pad gripping unit 5 is fixedly mounted on one end of the control cylinder 311. Through this technical solution, the extension and retraction of the control cylinder 311 can directly drive the pad gripping unit 5 to move rapidly along the Y-axis, usually towards or away from the pad feeding mechanism, completing the final stage of the gripping and releasing action.

[0062] Example 1 of the gasket gripping unit 5:

[0063] See Figure 12 As shown, to achieve a tension-type fixing method, the gasket gripping unit 5 includes a three-jaw cylinder 502 and first gripping parts 503. The three-jaw cylinder 502 is mounted on a fixed bracket 501, which is fixedly connected to the output end of the control cylinder 311 of the conveying assembly 3. Each of the three moving ends of the three-jaw cylinder 502 is fixedly connected to a first gripping part 503. Through this technical solution, when the three-jaw cylinder 502 is activated, the three first gripping parts 503 synchronously open or retract radially, achieving reliable gripping and release by tensioning the inner hole of the gasket 7 from within. This three-point uniform tension effectively avoids damaging the inner wall of the gasket, and provides a large gripping force and good stability.

[0064] Example 2 of the gasket gripping unit 5:

[0065] See Figure 13 and Figure 14 As shown, based on Embodiment 1 of the gasket gripping unit 5, in order to improve the success rate and reliability of gripping, even when there may be some offset when the gasket gripping unit 5 is aligned with the gasket, a floating unit is also provided between the three-jaw cylinder 502 and the fixed foot 501 of the gasket gripping unit 5. The floating unit includes a first U-shaped frame 505, a first offset block 507, a second U-shaped frame 509, and a second offset block 511. The first U-shaped frame 505 is fixedly installed on the bottom surface of the fixed foot 501, and a first guide rod 506 is fixedly connected to the inner side of the first U-shaped frame 505. A first offset block 507 is slidably connected to the first guide rod 506. A first spring 508 is fixedly connected between the first offset block 507 and the first U-shaped frame 505, which is used to make the first offset block 507 tend to return to the center position of the first guide rod 506. A second U-shaped frame 509 is fixedly connected to the bottom surface of the first offset block 507. A second guide rod 510 is fixedly connected to the inner side of the second U-shaped frame 509. A second offset block 511 is slidably connected to the second guide rod 510. A second spring 512 is fixedly connected between the second offset block 511 and the second U-shaped frame 509, which is used to make the second offset block 511 tend to return to the center position of the second guide rod 510. A three-jaw cylinder 502 is fixedly connected to the bottom surface of the second offset block 511. The three moving ends of the three-jaw cylinder 502 are all fixedly connected to the second gripping part 504. With this technical solution, if the second gripping part 504 has a positional deviation in the plane with the inner hole of the pad during the process of lowering and gripping the pad, the floating unit allows the three-jaw cylinder 502 to make a slight translation in the direction of the first guide rod 506 and the second guide rod 510, that is, in the mutually perpendicular X and Y directions, in order to compensate for the alignment error, achieve adaptive centering, and ensure that the gripping action is completed smoothly.

[0066] Furthermore, to ensure smoother alignment of the pad during self-alignment and provide reliable anti-slip protection after gripping, the bottom of the second gripping part 504 is provided with inclined claws 5041. The three inclined claws 5041 combined form a conical structure, facilitating the alignment of the pad during initial contact. A vertical plane is also provided on the side wall of the inclined claws 5041, and an anti-slip layer 5042, such as a vulcanized rubber or polyurethane layer, is provided on the vertical plane. Through this technical solution, the conical inclined surface helps with initial alignment before the claws expand; while the anti-slip layer 5042 provides additional anti-slip protection after the claws tighten through friction with the inner wall of the pad's hole, especially suitable for working conditions with lubricating oil or slight vibration.
