Abstract

This invention discloses an automotive gear inspection device, relating to the field of automotive gear inspection technology. It includes an inspection platform with a mounting plate on its top surface. The mounting plate has multiple inspection mechanisms on its top surface, a conveyor belt, an inverted "L"-shaped mounting frame, and multiple robotic arms. The inverted "L"-shaped mounting frame has an auxiliary mechanism and a pushing mechanism. The locking block of the auxiliary mechanism pre-positions the gear to be inspected circumferentially on the positioning seat, automatically correcting tooth position deviations caused by the robotic arms releasing material. This avoids the risk of tooth tip collisions from the source, effectively protecting the tooth surfaces of the standard gear and the gear to be inspected from impact damage. Simultaneously, in conjunction with an abnormal triggering structure consisting of a spring, guide rod, abutment block, and control switch, it can identify out-of-range or missing-tooth defective products before meshing, providing timely warnings via an alarm to avoid invalid inspections and damage to the standard gear.

Description

Technical Field

[0001] This invention belongs to the field of automotive gear testing technology, specifically an automotive gear testing device. Background Technology

[0002] As electric drive systems for new energy vehicles develop towards higher speeds and higher power densities, gears, as the core components of power transmission, are becoming increasingly precise during production. The transmission efficiency of gears directly affects the driving range of the entire vehicle. Therefore, early detection of micro-defects through component-level inspection can avoid batch rework and assembly scrapping losses caused by discovering problems only after assembly. Gear inspection has become a key link in ensuring performance, safety, and driving range in the manufacturing of new energy vehicles.

[0003] Currently, most gear double-sided meshing detection devices use a robotic arm to hold the gear to be tested to the detection station. Although the robotic arm can adjust the circumferential meshing angle of the gear, during the lowering process, the inertial force at the end of the robotic arm and the vibration generated by the positioning collision often cause the gear to rotate slightly in the circumferential direction, resulting in tooth position displacement. When the standard gear then approaches and meshes with the gear to be tested, the risk of tooth tip to tooth tip aligning increases significantly, which can easily cause tooth collision and damage to both the gear to be tested and the standard gear. In addition, this process relies on the same robotic arm to complete the unloading, the unloading and loading actions are sequential, the equipment has a long standby time, and the overall detection efficiency is difficult to meet the needs of mass production.

[0016] As a further preferred embodiment of this technical solution: the circumferential surface of the guide rod is slidably sleeved on the inner ring of the spring, and the abutment block is in movable contact with the surface of the control switch.

[0017] As a further preferred embodiment of this technical solution: the side wall of the connector is detachably equipped with a reinforcing plate, and the bottom of the reinforcing plate is fixedly connected with a lifting ring, which is sleeved on the outer circumferential wall of the positioning seat.

The structure design of the multi-station inspection mechanism can simultaneously complete the double-sided meshing inspection of multiple gears, which significantly improves the overall inspection efficiency. It can adapt to the large-scale and continuous production inspection cycle of new energy vehicle gears and meet the capacity requirements of large-scale manufacturing. Attached Figure Description

[0037] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1:

[0039] Please see Figures 1-8 This application provides an automotive gear testing device, including a testing platform 1, a mounting plate 2 mounted on the top surface of the testing platform 1, a plurality of testing mechanisms 5 provided on the top surface of the mounting plate 2, a conveyor belt 4, an inverted "L"-shaped mounting frame 6 and a plurality of robotic arms 3 mounted on the top surface of the mounting plate 2, and an auxiliary mechanism 7 and a pushing mechanism 8 provided on the inverted "L"-shaped mounting frame 6.

[0040] The entire testing table 1 is made of cast iron, with surface flatness controlled within 0.02mm. It has excellent vibration absorption and damping performance, which can effectively isolate the vibration of the workshop floor and the vibration of the equipment itself, and avoid interfering with the gear meshing detection accuracy.

[0041] Mounting plate 2 is made of No. 45 steel with heat treatment and high-frequency quenching on the surface. It is also ground to ensure the flatness of the entire mounting reference. As a unified mounting base for each work station, it is not easily deformed during long-term use.

[0042] The detection mechanism 5 includes multiple mounting plates 51 that are slidably connected to the top surface of the mounting plate 2. Each mounting plate 51 has a detection seat 52 that can be detachably installed on its top surface. A standard gear 54 is rotatably provided above the detection seat 52. A displacement sensor, an alarm device 2, and a controller are installed on the outer wall of each detection seat 52. The displacement sensor, the alarm device 2, and the controller are electrically connected.

[0043] The detection seat 52 is machined from HT200 cast iron blank, which has good damping and shock absorption properties, and can reduce the slight vibration caused by the motor rotation, providing a stable rotation support reference for the rotating shaft 53 and the standard gear 54.

[0044] The top surface of the mounting plate 2 can also be detachably fitted with multiple positioning seats 55 that work in conjunction with the detection seat 52 and the robotic arm 3;

[0045] The positioning seat 55 is machined as a whole from Cr12MoV mold steel, with a quenching hardness of HRC58-62 and excellent wear resistance. The positioning inner hole and the gear inner hole adopt H7 / g6 clearance fit, which not only ensures accurate radial positioning, but also facilitates smooth gear loading and unloading.

[0046] The top edge of the positioning seat 55 is chamfered to guide the gear to be tested to be smoothly installed into place.

[0047] A conveying device for continuously feeding the gears to be tested is placed on one side of the testing table 1. Multiple robotic arms 3 respectively clamp the gears to be tested and place them on multiple positioning seats 55 for testing. The conveyor belt 4 works in conjunction with the pushing mechanism 8 to transport the tested gears to the receiving area.

[0048] Robotic arm 3 is a six-axis industrial lightweight robotic arm with a flexible pneumatic gripper at the end. The gripping force is continuously adjustable from 0 to 50N. Polyurethane pads are attached to the inside of the gripper to avoid damaging the precision-machined tooth surface and end face of the gear.

[0049] When the robotic arm 3 completes the placement of the gear, the gear under test is prone to slight circumferential rotation due to end inertia and positioning impact, and the tooth angle will randomly shift. If the standard gear 54 is directly brought close to mesh, it is very easy for the tooth tips to collide. Therefore, the auxiliary mechanism 7 is required to complete the tooth direction pre-correction before meshing.

[0050] The auxiliary mechanism 7 includes an electric push rod 71 that can be detachably installed on the top and bottom surfaces of the inverted "L"-shaped mounting bracket 6. The telescopic end of the electric push rod 71 is detachably installed with multiple fixing brackets 74 via fixing plate 72. Each fixing bracket 74 has a control switch 702 detachably installed on its top and bottom surfaces.

[0051] The electric actuator 71 is a servo direct-drive electric actuator with stepless adjustable lifting speed. The overall lifting action of the drive auxiliary mechanism 7 is smooth and shock-free.

[0052] The inverted "L" shaped mounting bracket 6 is made of Q235 steel plate, bent and welded, and stress-relief treatment is performed after welding to ensure the load-bearing rigidity of the cantilever end and prevent sagging under long-term load.

[0053] Both the fixed plate 72 and the fixed bracket 74 are made of 6061-T6 aluminum alloy, which is lightweight while having sufficient structural rigidity, effectively reducing the inertia of lifting load and improving the start-stop response speed.

[0054] The control switch 702 uses an industrial-grade micro switch with a triggering force of 1N and a protection rating of IP65. It can adapt to production conditions with a lot of dust and oil in the workshop, and the triggering signal is stable and reliable.

[0055] Each mounting bracket 74 is also equipped with an alarm device, which is electrically connected to the control switch 702. The alarm device is an industrial-grade integrated audible and visual alarm with an alarm decibel value of 85dB and a light flashing frequency of 2Hz. After being triggered, it will continue to alarm until manually reset, which facilitates the staff to quickly locate abnormal work positions.

[0056] A connector 77 is connected to the bottom of the fixing frame 74 via a spring 76. A guide rod 75 is fixedly connected to the top surface of the connector 77. The top end of the guide rod 75 passes through the bottom plate of the fixing frame 74 and is fixedly connected to an abutment block 701.

[0057] Spring 76 is made of 65Mn spring steel and has a stiffness set at 10N / mm.

[0058] The guide rod 75 is made of bearing steel and has a small clearance fit with the guide hole of the fixed frame 74, so that the lifting and sliding are smooth and without jamming, ensuring the precise trigger position of the abutment block 701;

[0059] The contact block 701 is made of brass, which is relatively soft and will not damage the contacts of the control switch 702 when triggered, thus extending the service life of the switch.

[0060] Two locking blocks 78 are fixedly connected to the bottom of each connector 77. Each locking block 78 has a chamfer at the bottom for guidance, and a lifting ring 703 that rises and falls synchronously with the locking block 78 is provided below the locking block 78.

[0061] Both the connector 77 and the locking block 78 are made of mold steel, which is wear-resistant and impact-resistant, and is not prone to indentation and wear when in long-term contact with the gear teeth.

[0062] The bottom chamfered surface of the locking block 78 is mirror-polished, which allows the gear to rotate smoothly during the downward pressing process. It automatically corrects tooth position misalignment and will not scratch the tooth tip and tooth surface. The groove width between the locking blocks 78 is adapted to the tooth thickness of the gear, and can completely restrict the circumferential rotation of the gear after being locked in.

[0063] The telescopic end of the electric push rod 71 is detachably connected to the center of the top surface of the fixed plate 72. Multiple fixed rods 73 are fixedly connected to the bottom surface of the fixed plate 72, and the bottom ends of the multiple fixed rods 73 are detachably connected to the top surface of the multiple fixed frames 74 respectively.

[0064] The fixing rod 73 is made of No. 45 steel round bar to ensure that the bottom surface of the multi-station locking block 78 is on the same horizontal plane.

[0065] The circumferential surface of the guide rod 75 is slidably sleeved on the inner ring of the spring 76, and the abutment block 701 is in movable contact with the surface of the control switch 702.

[0066] A reinforcing plate 79 is detachably installed on the side wall of the connector 77. A lifting ring 703 is fixedly connected to the bottom of the reinforcing plate 79. The lifting ring 703 is sleeved on the outer circumferential wall of the positioning seat 55. When the gear to be tested is placed on the positioning seat 55, the lifting ring 703 is located below the gear to be tested.

[0067] The reinforcing plate 79 and the lifting ring 703 are made of aluminum alloy as one piece. The inner ring of the lifting ring 703 and the outer wall of the positioning seat 55 with the largest circumference are fitted with clearance, so that there is no swaying or jamming during the lifting process.

[0068] A 0.5mm thick polyurethane buffer pad is attached to the lifting end face of the 703 lifting ring, providing flexible cushioning during lifting contact and preventing impact damage to the gear end face.

[0069] In practice, the robotic arm 3 places multiple gears to be tested onto multiple positioning seats 55. At this time, the gears to be tested only complete radial positioning, and the circumferential tooth angle has random offset. They cannot directly enter the meshing detection process.

[0070] The extension end of the electric push rod 71 drives the fixed plate 72 to descend, thereby driving multiple connecting parts 77 to descend synchronously, which in turn drives the locking block 78 to descend. The chamfer at the bottom of the locking block 78 guides a tooth of the gear to be tested to be tightly inserted into the locking groove of the locking block 78 for limiting. The chamfer can generate circumferential driving force on the deflected gear, automatically correct the tooth angle, and ensure that the subsequent standard gear 54 can mesh smoothly with the gear to be tested, thus avoiding the risk of tooth tip collision from the root.

[0071] When the locking block 78 is descending and the chamfered guide still cannot insert the tooth to be tested into the locking groove, it indicates that the gear to be tested has defects such as missing teeth, severe tooth deformation, or tooth position offset that exceeds the correction range. At this time, the electric push rod 71 drives the connecting piece 77 to continue descending, which will compress the spring 76 to contract, thereby driving the guide rod 75 to slide upward, causing the abutment block 701 to contact the control switch 702, thereby triggering the alarm to start, reminding the staff to remove the abnormal gear to be tested in time to avoid damage to the standard gear 54 during subsequent meshing.

[0072] After multiple locking blocks 78 limit and fix multiple gears to be tested, the circumferential tooth position of the gears to be tested has been corrected, completely eliminating the risk of collision between tooth tips. After the detection mechanism 5 drives the standard gear 54 to slide and mesh with multiple gears to be tested, the extension end of the electric push rod 71 drives multiple locking blocks 78 to rise and leave the gears to be tested. The multiple standard gears 54 rotate to perform double-sided meshing detection on the gears to be tested.

[0073] After the test is completed, the telescopic end of the electric push rod 71 rises again, which can drive multiple lifting rings 703 to rise synchronously, lift up multiple gears that have been tested, and lift the gears away from the positioning seat 55, leaving a lateral pushing space, and then transfer them to the conveyor belt 4 in conjunction with the pushing mechanism 8.

[0074] Alarm 2 is used to alert staff that the gear at the corresponding position is a defective gear, making it easier for workers to sort and remove it from conveyor belt 4.

[0075] Example 2

[0076] Based on Embodiment 1, the vertical plate of the inverted "L"-shaped mounting bracket 6 is detachably equipped with an electric telescopic rod 81. The telescopic end of the electric telescopic rod 81 is detachably equipped with a fixing plate 3 82. Multiple fixing rods 3 83 are fixedly connected to the surface of the fixing plate 3 82. An arc-shaped push plate 84 is fixedly connected to the end of each fixing rod 3 83 away from the fixing plate 3 82. The electric telescopic rod 81 uses a servo electric cylinder, and the pushing action is smooth and impact-free. The fixing plate 3 82 and the fixing rods 3 83 are both made of aluminum alloy. The lightweight design reduces the load inertia of the electric telescopic rod 81 and improves the pushing response speed.

[0077] The arc-shaped push plate 84 is made of aluminum alloy substrate, with a 1mm thick nylon pad attached to the working surface. When it comes into contact with the outer circle of the gear, it is a flexible contact that will not bump the tooth tip and tooth surface, effectively protecting the precision of gear machining.

[0078] The inner radius of the arc-shaped pusher plate 84 matches the outer radius of the gear to be tested, resulting in a large contact area. During the pushing process, the gear is subjected to uniform force, preventing tilting and jamming.

[0079] The conveyor belt 4 is located on the opposite side of the multiple arc-shaped push plates 84, and the conveyor belt 4 is used in conjunction with the arc-shaped push plates 84;

[0080] Conveyor belt 4 is made of PVC anti-static flat belt with anti-slip treatment on the surface, so that the workpiece does not slip during the conveying process.

[0081] In specific implementation, after the lifting ring 703 of the auxiliary mechanism 7 lifts the tested gear away from the positioning seat 55, the gear is lifted to a position at the same height as the arc-shaped push plate 84, and the bottom surface of the gear is at the same level as the top surface of the conveyor belt 4.

[0082] The electric telescopic rod 81 extends, pushing the fixed plate 3 82, the fixed rod 3 83 and the arc-shaped push plate 84 forward. After the arc-shaped push plate 84 contacts the outer circle of the gear, it pushes the gear laterally to the surface of the conveyor belt 4 at a uniform speed. The conveyor belt 4 starts and continuously transports qualified and unqualified workpieces to the discharge end.

[0083] The feeding mechanism 8 independently completes the unloading action, and the robotic arm 3 does not need to participate in the unloading process. While performing testing at the testing station, the robotic arm 3 can simultaneously grab the next batch of gears to be tested for loading preparation, realizing parallel operation of multiple processes such as loading, testing, and unloading, greatly shortening the equipment standby waiting time, improving the overall efficiency of batch gear testing, and adapting to the production rhythm of large-scale continuous testing of gears in new energy vehicles.

[0084] Example 3

[0085] Based on the above embodiments, each detection seat 52 has multiple mounting slots 501 on its outer wall. A drive motor is installed in the inner cavity of the mounting slot 501. A rotating shaft 53 is detachably installed at the output end of the drive motor. The rotating shaft 53 is rotatably sleeved on the top surface of the detection seat 52. A standard gear 54 is fixedly sleeved on the outer circumference of the rotating shaft 53.

[0086] The drive motor is a 42 series two-phase stepper motor, which runs smoothly and with low noise, providing stable rotational power for the standard gear 54.

[0087] The rotating shaft 53 is made of alloy steel and heat-treated, and the surface is treated with high-frequency quenching. A deep groove ball bearing is installed between the rotating shaft 53 and the detection seat 52. The rotation clearance is small and the radial runout is small, which ensures the rotation accuracy of the standard gear 54.

[0088] The standard gear 54 is made of bearing steel and is used as a testing reference piece for regular calibration to ensure accurate and reliable test results.

[0089] The testing mechanism 5 also includes an electric slide 56 that can be detachably installed on the top surface of the mounting plate 2. The sliding end of the electric slide 56 is detachably installed with a fixing plate 57. Multiple fixing rods 58 are fixedly connected to the surface of the fixing plate 57, and connecting plates 59 are fixedly connected to the surface of the fixing rods 58. The multiple connecting plates 59 are detachably installed on the outer wall of the multiple testing seats 52 respectively.

[0090] The electric slide table 56 adopts a ball screw drive linear module slide table, which runs smoothly and can simultaneously drive multiple sets of detection seats 52 to perform feed and retraction movements.

[0091] The fixing plate 57, fixing rod 58 and connecting plate 59 are all made of No. 45 steel, which has high connection strength and ensures that multiple sets of detection seats 52 move synchronously without misalignment and that the feed amount is consistent.

[0092] In practice, the circumferential tooth position correction of the gear to be tested is completed by the auxiliary mechanism 7, and there is no safety hazard of tooth tip collision.

[0093] The electric slide table 56 drives the fixed plate 57, the fixed rod 58, and the connecting plate 59 to move synchronously, pulling all the test seats 52 to be smoothly fed towards the positioning seat 55, so that the standard gear 54 and the gear to be tested can complete the impact-free meshing;

[0094] The drive motor inside the mounting slot 501 drives the rotating shaft 53 and the standard gear 54 to rotate continuously, and performs double-sided meshing detection.

[0095] The displacement sensor uses a laser displacement sensor with a resolution of 0.001mm, which can accurately capture the tiny radial runout during gear meshing.

[0096] The controller adopts a PLC programmable controller, which integrates multi-station detection logic, alarm logic and loading / unloading linkage logic, and can realize fully automatic detection cycle;

[0097] Alarm II uses a three-color columnar indicator light: green for normal detection, yellow for standby, and red for failure alarm. The status is intuitive and easy to see, making it convenient for on-site personnel to monitor.

[0098] The displacement sensor collects the radial displacement change signal in real time during the meshing process and transmits the signal to the controller for data analysis;

[0099] When the test data exceeds the preset qualified threshold, the controller triggers the second alarm and marks the gear at that station as a defective part, so that the staff can remove the gear mark later.

[0100] After all tests are completed, the electric slide 56 drives all the test seats 52 back to their original positions, waiting for the next test cycle.

[0101] The above embodiments are only used to illustrate the technical methods of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
