Description

Technical Field

[0001] This utility model belongs to the technical field of transmission component testing equipment, and in particular relates to an automatic loading and unloading device for gear runout detection. Background Technology

[0002] Gears are common components in mechanical equipment for power transmission and motion control. Their dimensional accuracy (such as diameter tolerance and length tolerance) and running accuracy (such as radial runout and axial runout) directly determine the overall machine's operational stability, transmission efficiency, and service life. Therefore, gear runout testing is a crucial step in evaluating gear machining accuracy. It is primarily achieved by measuring the radial or axial runout of the gear ring relative to the gear axis. During testing, the gear is fixed and rotated. The runout meter probe contacts the tooth surface or addendum circle. As the gear rotates one revolution, the maximum and minimum pointer readings are recorded; the difference is the runout error.

[0003] In the traditional gear runout testing process, a combination of manual loading and unloading and a separate testing instrument is often used. In practice, workers need to take out the gears to be tested one by one from the material box, manually transfer the gears to the top of the runout tester or the chuck, manually adjust the positioning, and then carry out the runout test. After the test is completed, qualified and unqualified parts need to be sorted and stored manually. This traditional operating mode has many drawbacks: First, the inspection efficiency is extremely low. The manual handling, positioning, and data recording processes are time-consuming, with the inspection time for a single part typically being 3-5 minutes, which is difficult to match the inspection needs of large-scale production lines. Second, the labor intensity for workers is high. The repetitive handling of gears for extended periods can easily lead to physical strain, and the need to maintain a high level of concentration at all times can easily cause fatigue. Third, the consistency of inspection standards is poor. The accuracy of manual positioning is affected by operating experience and fatigue levels, and different inspection results may occur for the same batch of parts. Furthermore, manual data recording is prone to errors and omissions. To address this issue, we provide an automatic loading and unloading device for gear runout detection. Utility Model Content

[0004] The purpose of this invention is to provide an automatic loading and unloading device for gear runout detection. By combining an automated loading and unloading mechanism with a vision positioning and rotation detection mechanism, it solves the problems of low detection efficiency, high labor intensity of manual operation, and poor detection consistency in existing gear runout detection devices.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0006] This utility model relates to an automatic loading and unloading device for gear runout detection, comprising a platform, a loading assembly on one side of the top of the platform, a detection table fixedly connected to the top of the platform, a conveyor belt on the top of the detection table, and a unloading assembly on one side of the platform. The loading assembly includes a storage bin, the bottom of which is fixedly connected to the top of the platform. A pusher plate is connected through one side of the storage bin, and a pusher motor is fixedly connected to the bottom of one side of the storage bin. A screw is fixedly connected to the output end of the pusher motor, and a threaded seat is fixedly connected to one side of the bottom of the pusher plate. The surface of the screw is threadedly connected to the inner cavity of the threaded seat. The unloading assembly includes a unloading motor, which is fixedly connected to the bottom of one side of the platform. The output shaft of the unloading motor is fixedly connected to an unloading bin, and one side of the unloading bin is movably connected to one side of the detection table.

[0007] The present invention is further configured such that a detection component is provided on the top of the detection platform, the detection component includes a detection frame, the bottom of the detection frame is fixedly connected to the top of the detection platform, an industrial camera is provided on one side of the top of the detection frame, a robotic arm is provided on the top of the inner cavity of the detection frame, a fixed shell is fixedly connected to one end of the robotic arm, a drive motor is fixedly connected to the top of the inner cavity of the fixed shell, a turntable is fixedly connected to the output shaft of the drive motor, a suction cup is fixedly connected to the bottom of the turntable, an electric push rod is fixedly connected to one side of the inner cavity of the detection frame, a mounting frame is fixedly connected to the telescopic shaft of the electric push rod, and a detector is provided in the inner cavity of the mounting frame. The industrial camera identifies the position and posture of the gear to be inspected on the conveyor belt and sends a positioning signal to the robotic arm. The robotic arm drives the suction cup to move downward to pick up the gear according to the signal and moves it to the detection station. The drive motor drives the turntable to rotate, so that the gear rotates under the suction of the suction cup. The detector moves to the detection position under the push of the electric push rod to detect the rotating gear.

[0008] The present invention is further configured such that a discharge port is provided at the bottom of one side of the storage bin, and a guide platform is provided in the inner cavity of the discharge port. The pusher plate pushes the gear out of the storage bin, and the gear slides down the inclined surface of the guide platform through the discharge port onto the conveyor belt to achieve a smooth transition. The inclined design of the guide platform reduces the impact of the gear falling and prevents collision damage.

[0009] The present invention is further configured such that baffles are fixedly connected to the front and rear sides of one side of the storage bin. The baffles are located above the conveyor belt and are arranged along both sides of the conveyor belt to restrict the lateral displacement of the gears during the pushing process, ensure that they enter the detection area along the predetermined path, prevent the gears from falling off or misaligning during the conveying process, and improve the feeding accuracy.

[0010] The present invention is further configured such that a support frame is fixedly connected to the bottom of the platform, and anti-slip pads are fixedly connected to both sides of the bottom of the support frame. The support frame provides structural support for the entire device and isolates it from the ground. The anti-slip pads increase the friction at the bottom and prevent the equipment from shifting during operation. The support frame distributes the weight and vibration of the equipment, and the anti-slip pads prevent slippage and ensure a stable testing process.

[0011] The present invention is further configured such that a limiting frame is fixedly connected to one side of the storage bin, the inner cavity of the limiting frame is movably connected to the surface of the pusher plate, and the pusher plate moves linearly along the inner cavity of the limiting frame under the drive of the screw. The limiting frame constrains its movement trajectory, prevents swaying during the pushing process, avoids the tilting of the pusher plate due to uneven force or transmission error, and ensures consistency in each push.

[0012] The present invention is further configured such that an annular groove is formed on the inner wall of the fixed shell, and a limiting ring is fixedly connected to the surface of the turntable. The surface of the limiting ring is movably connected to the inner cavity of the annular groove. The annular groove is formed on the inner wall of the fixed shell, and the limiting ring is fixed on the surface of the turntable. The two are movably connected. When the turntable rotates under the drive of the drive motor, the limiting ring slides along the annular groove to realize the axial limiting and radial support of the turntable and prevent the turntable from shaking or deviating.

[0013] The present invention is further configured such that a side groove is provided on one side of the inner cavity of the detection frame, and a movable block is movably connected to the inner cavity of the side groove. One side of the movable block is fixedly connected to the surface of the mounting frame. When the electric push rod pushes the mounting frame, the movable block slides along the side groove, guiding the mounting frame to move in a straight line, ensuring that the detector approaches or moves away from the gear along a preset trajectory, avoiding the mounting frame from twisting or shifting during movement, and ensuring the alignment accuracy of the detector.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model integrates automated feeding, visual positioning, robotic arm gripping, and rotation detection, achieving fully unmanned operation of gears from storage to inspection and sorting. Compared with the traditional manual picking, manual positioning, and step-by-step inspection methods, the inspection time for a single piece is greatly shortened. At the same time, the mechanical positioning and programmed inspection process completely eliminate human error and ensure a high degree of consistency in the inspection standards of the same batch of gears.

[0016] 2. This utility model adopts a structure of batch feeding from storage bins, automatic pushing by a pushing mechanism, conveyor belt conveying, robotic arm grasping, and automatic sorting from unloading bins. It replaces repetitive manual labor such as manual picking, handling, positioning, and sorting, effectively avoiding worker fatigue and physical strain caused by long-term operation. In addition, the collaborative work of industrial cameras and detectors realizes the automation and digitization of the detection process, eliminating the problems of misrecording and omissions that may occur in manual recording, and improving the accuracy and completeness of detection data.

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figure 1-5This utility model is an automatic loading and unloading device for gear runout detection, including a platform 1, a loading component 2 disposed on one side of the top of the platform 1, a detection table 3 fixedly connected to the top of the platform 1, a conveyor belt 4 disposed on the top of the detection table 3, and a unloading component 5 disposed on one side of the platform 1. The loading component 2 includes a storage bin 201, the bottom of which is fixedly connected to the top of the platform 1, and a pusher plate 202 penetratingly connected to one side of the storage bin 201. A pusher motor 203 is fixedly connected, and a screw 204 is fixedly connected to the output end of the pusher motor 203. A threaded seat 205 is fixedly connected to one side of the bottom of the pusher plate 202. The surface of the screw 204 is threadedly connected to the inner cavity of the threaded seat 205. The unloading assembly 5 includes an unloading motor 501, which is fixedly connected to the bottom of one side of the platform 1.

[0026] Specifically: The core of the feeding assembly 2 is the storage bin 201, which is vertically fixed on the platform 1 and used to stack and store gears to be tested. On the side of the storage bin 201 facing the testing platform 3, a reciprocating pusher plate 202 is horizontally installed. A pusher motor 203 is installed on the bottom outer side of the storage bin 201. The output shaft of the pusher motor 203 is connected to a horizontally arranged screw 204. A threaded seat 205 matching the screw 204 is fixed at the bottom of the pusher plate 202. The screw 204 is screwed into the threaded seat 205. When the pusher motor 203 is started, the screw 204 rotates, driving the threaded seat 205 and the pusher plate 202 to move linearly along the axial direction of the screw 204, thereby smoothly pushing out the bottom gear of the storage bin 201. The unloading assembly 5 mainly includes an unloading motor 501 and a rotatable unloading bin 502. The feeding motor 501 is fixed on the side of the platform 1, and its output shaft is directly connected to the bottom of the feeding bin 502, driving the feeding bin 502 to rotate in a horizontal position. The rotation of the feeding bin 502 guides the gears that meet the standards and the gears that do not meet the standards to different receiving devices.

[0027] A detection assembly 6 is installed on the top of the detection table 3. The detection assembly 6 includes a detection frame 601, the bottom of which is fixedly connected to the top of the detection table 3. An industrial camera 602 is installed on one side of the top of the detection frame 601. A robotic arm 603 is installed on the top of the inner cavity of the detection frame 601. A fixed housing 604 is fixedly connected to one end of the robotic arm 603. A drive motor 605 is fixedly connected to the top of the inner cavity of the fixed housing 604. A turntable 606 is fixedly connected to the output shaft of the drive motor 605. A suction cup 607 is fixedly connected to the bottom of the turntable 606. An electric push rod 608 is fixedly connected to one side of the inner cavity of the detection frame 601. A mounting bracket 609 is fixedly connected to the telescopic shaft of the electric push rod 608. A detector 61 is installed in the inner cavity of the mounting bracket 609. 0. A discharge port is provided at the bottom of one side of the storage bin 201. A guide platform is provided in the inner cavity of the discharge port. Baffles are fixedly connected to the front and rear sides of one side of the storage bin 201. The baffles are located above the conveyor belt 4. A support frame 7 is fixedly connected to the bottom of the platform 1. Anti-slip pads are fixedly connected to both sides of the bottom of the support frame 7. A limit frame is fixedly connected to one side of the storage bin 201. The inner cavity of the limit frame is movably connected to the surface of the push plate 202. An annular groove is provided in the inner wall of the fixed shell 604. A limit ring is fixedly connected to the surface of the turntable 606. The surface of the limit ring is movably connected to the inner cavity of the annular groove. A side groove is provided on one side of the inner cavity of the detection frame 601. A movable block is movably connected to the inner cavity of the side groove. One side of the movable block is fixedly connected to the surface of the mounting frame 609.

[0028] Specifically: Industrial camera 602 identifies the position and orientation of the gear to be inspected on conveyor belt 4 and sends a positioning signal to robotic arm 603. Based on the signal, robotic arm 603 moves suction cup 607 downwards to pick up the gear and move it to the inspection station. Drive motor 605 drives turntable 606 to rotate, causing the gear to rotate under the suction cup 607. Inspection instrument 610 moves to the inspection position under the push of electric push rod 608 to inspect the rotating gear. Push plate 202 pushes the gear out of storage bin 201. The gear slides down the inclined guide platform onto conveyor belt 4 through the discharge port, achieving a smooth transition. The inclined design of the guide platform reduces the impact of the gear falling and prevents damage from bumps. Baffles are arranged along both sides of conveyor belt 4 to limit the lateral deviation of the gear during pushing, ensuring it enters the inspection area along a predetermined path, preventing the gear from falling off or misaligning during conveying, and improving feeding accuracy. Support frame 7 provides structural support for the entire device and isolates it from the ground. Anti-slip pads increase bottom friction. To prevent equipment displacement during operation, the support frame 7 distributes the weight and vibration of the equipment, and the anti-slip pad prevents slippage, ensuring a stable testing process. The pusher plate 202 moves linearly along the inner cavity of the limiting frame under the drive of the screw 204. The limiting frame constrains its movement trajectory, preventing swaying during the pushing process and avoiding tilting of the pusher plate 202 due to uneven force or transmission error, ensuring consistency in each push. An annular groove is opened on the inner wall of the fixed shell 604, and a limiting ring is fixed on the surface of the turntable 606. The two are movably connected. When the turntable 606 rotates under the drive of the drive motor 605, the limiting ring slides along the annular groove, realizing axial limiting and radial support of the turntable 606, preventing the turntable 606 from shaking or shifting. When the electric push rod 608 pushes the mounting frame 609, the movable block slides along the side groove, guiding the mounting frame 609 to move linearly, ensuring that the detector 610 approaches or moves away from the gear along the preset trajectory, avoiding twisting or shifting of the mounting frame 609 during movement, and ensuring the alignment accuracy of the detector 610.

[0029] The working principle of this utility model is as follows: The gears to be tested are neatly stacked in the storage bin 201, ensuring that the gear axes are aligned. The pusher motor 203 is started, driving the screw 204 to rotate, which in turn drives the pusher plate 202 to smoothly advance along the limiting frame, pushing the bottom gear of the storage bin 201 out of the discharge port. The gear slides down the inclined surface of the guide table onto the conveyor belt 4. The baffle restricts its lateral displacement, ensuring that the gear enters the detection area along the predetermined path. The conveyor belt 4 transports the gear at a uniform speed to the field of view of the industrial camera 602. The industrial camera 602 acquires images of the gear, identifies its position and posture, and sends coordinate signals to the control system of the robotic arm 603. The robotic arm 603 moves the fixed shell 604 and the suction cup 607 to directly above the gear according to the signal. The suction cup 607 is energized to attract the gear. The gear is lifted and moved to the inspection station. The drive motor 605 drives the turntable 606 to rotate, and the gear rotates synchronously under the suction cup 607. The electric push rod 608 pushes the mounting bracket 609 to move linearly along the side groove, so that the side head of the detector 610 contacts the rotating gear and dynamically detects its radial runout, end face runout, and other running accuracy. The detection data is uploaded to the control system in real time. The system automatically determines whether the gear is qualified according to the preset tolerance range. After the inspection is completed, the robotic arm 603 moves the gear to the top of the unloading bin 502. The suction cup 607 is de-energized and releases the gear. The control system drives the unloading motor 501 to rotate according to the detection results, causing the unloading bin 502 to deflect to the corresponding angle, guiding qualified and unqualified parts to different collection containers. After completion, the unloading bin 502 is reset, ready to receive the next gear.
