Description

Technical Field

[0001] This invention relates to the field of vehicle frame inspection, and more specifically, to an inspection system for the production of electric vehicle frames based on screening components. Background Technology

[0002] The electric vehicle frame, as the most critical structure in an electric vehicle, plays a vital role in connecting and supporting various components. Currently, the main materials used to manufacture electric vehicle frames include steel, aluminum alloy, titanium alloy, magnesium alloy, carbon fiber, etc. Among these, steel and aluminum alloy frames are the most widely used, and both are generally manufactured using welding processes.

[0003] For example, Chinese Patent Publication No. CN216283223U discloses an electric vehicle frame testing device, including a movable base and a maintenance mechanism and a clamping mechanism disposed on the movable base. The clamping mechanism includes a first support rod and clamping parts on the first support rod for clamping the electric vehicle shell. The maintenance mechanism includes a first maintenance frame, a second maintenance frame, and a third maintenance frame. The lower parts of the second and third maintenance frames are connected to the upper part of the movable base through a second support rod. The lower part of the first maintenance frame is connected to the movable base in sequence through a side maintenance frame and a second support rod. This electric vehicle frame testing device, through the cooperation of the first, second, third, and side maintenance frames, can quickly detect the flatness and the size of holes in all directions on the electric vehicle frame. It is simple to operate and convenient to use, bringing great convenience to the maintenance work of the staff.

[0004] However, in the current technology, the traditional method of testing and screening electric vehicle frames during production involves placing the frame on a conveyor belt surface and passing it through multiple testing structures, with each test result marked. However, the overall testing requires the installation of multiple sets of detectors, making the testing process for electric vehicle frames cumbersome, inefficient, and unable to meet the current testing and screening needs. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, the technical problem to be solved by this invention is to propose an inspection system for electric vehicle frame production based on screening components. This system can overcome the problem that in the traditional inspection and screening process of electric vehicle frame production, the frame is placed on the surface of a conveyor belt and passes through multiple inspection structures in sequence, and the inspection is marked. However, the overall inspection requires the installation of multiple sets of detectors, which makes the inspection process of electric vehicle frames cumbersome, inefficient, and unable to meet the needs of existing inspection and screening.

[0006] To achieve this objective, the present invention adopts the following technical solution: This invention provides a testing system for electric bicycle frame production based on a screening component, including a main testing line frame. Vertical linear guide rails are fastened to three sides of the main testing line frame, and these vertical linear guide rails have a height difference. Positioning and adjusting dynamic components are slidably connected inside each vertical linear guide rail. Each positioning and adjusting dynamic component includes a displacement sliding seat, which is slidably connected inside the vertical linear guide rails. A curved frame is fastened to the side of the displacement sliding seat. A first clamp motor and a second clamp motor are fastened to the side surfaces of the curved frame, respectively. A sleeve is installed at the top end of the curved frame, a threaded post is installed at the bottom of the sleeve, and an arc-shaped toothed ridge post is installed at the bottom of the threaded post. The sleeve component drives the threaded column and the arc-shaped toothed column to form a lifting and sliding connection at the top of the crank frame. The arc-shaped toothed column has rotating teeth connected to its exterior via a stator-rotor structure. A collar is integrally formed at the bottom of each rotating tooth. A driving rotating tooth is meshed with the side end of each rotating tooth. The driving rotating tooth is connected to a second hoop motor. A small rotating gear is connected to the output end of the first hoop motor. The small rotating gear meshes with the threaded column. A telescopic support is installed at the bottom of the arc-shaped toothed column. A bearing groove rod is fastened to the side of the collar. An adjusting column is rotatably connected inside the bearing groove rod. A central driving rotating tooth is fastened to the side end of the adjusting column. The central driving rotating tooth meshes with the arc-shaped toothed column. In conjunction with the positioning and adjustment dynamic component, when it is necessary to inspect and screen the car frames conveyed on the surfaces of the two conveyor belts, the external logic controller sends a control command to start the first and second hoop motors, providing power to the positioning and adjustment dynamic component. Based on the inspection requirements, the external controller drives the small gear to rotate via the first hoop motor, causing the small gear to mesh with the threaded column, thus moving the threaded column up and down. This adjusts the height of the sleeve and the arc-shaped toothed bar. The telescopic support ensures that the arc-shaped toothed bar rises and falls synchronously during the lifting process and remains stable. Furthermore, during the lifting and lowering of the arc-shaped toothed bar, the central drive gear and the arc-shaped toothed bar form a meshing connection, facilitating the central drive gear to drive the bearing groove rod to adjust the rotation of the column. The movement causes the connected structures to rotate synchronously. Then, the external logic controller drives the rotating gear to rotate via the second hoop motor, causing the driving gear to mesh with the rotating gear and drive the rotating gear and its bottom collar to rotate. The rotating gear is located outside the arc-shaped toothed column and is connected through the stator and rotor structure. When the second hoop motor drives the rotating gear, the rotating gear drives the collar to rotate synchronously, forming an orientation angle adjustment. The whole is precisely adjusted according to the real-time detection position to ensure that the subsequent frame weld seam detection components, weld seam detection sensors, prestress detection sensors and pressure blocks can cover the entire frame surface. This improves the accuracy and efficiency of detection and screening, and also forms an automated operation, ensuring the quality control of the electric vehicle frame during the production process and improving detection efficiency.

[0007] In a preferred embodiment of the present invention, the side ends of the adjusting column are respectively fastened with a frame weld detection component, a position positioning connecting block and a motor drive box.

[0008] In a preferred embodiment of the present invention, the frame weld inspection assembly includes a sliding guide post, and the side end of the sliding guide post is equipped with a drive transverse rail via a connecting plate.

[0009] In a preferred embodiment of the present invention, multiple sets of ultrasonic detectors are installed at the bottom of the sliding guide post and the drive transverse rail, and a position weld detection frame is slidably connected inside the top of the sliding guide post and the drive transverse rail.

[0010] In a preferred embodiment of the present invention, a dual-axis pneumatic cylinder is installed at the center end of the position weld inspection frame, a connecting frame is installed at the bottom of the dual-axis pneumatic cylinder, and a weld inspection sensor and a prestress inspection sensor are respectively installed at the bottom of the connecting frame.

[0011] In a preferred embodiment of the present invention, a hydraulic telescopic rod is fastened to the bottom of the positioning connecting block, a pressure block is fastened to the bottom of the hydraulic telescopic rod, a stress sensor is installed on the side surface of the pressure block, and an automatic marking end is installed on the side of the pressure block.

[0012] In a preferred embodiment of the present invention, an angle rotation arm is connected to the output end of the motor drive box, and a surface X-ray detector is fastened to the side end of the angle rotation arm.

[0013] In a preferred embodiment of the present invention, a pulley structure is installed at the bottom of the main detection frame, and a drive energy-saving motor is installed at the top of the side end of the pulley structure.

[0014] In a preferred embodiment of the present invention, a support base plate is fastened to the bottom of the pulley structure and the drive energy-saving motor, and two sets of external conveyor belt structures are installed on the left and right sides of the support base plate.

[0015] In a preferred embodiment of the present invention, the vertical linear guide rail, the drive energy-saving motor, the first hoop motor, and the second hoop motor are connected to an external logic controller via signal connections.

[0016] The beneficial effects of this invention are as follows: This invention provides an inspection system for electric bicycle frame production based on a screening component. 1. When the frames conveyed on the conveyor belts on both sides need to be inspected and screened, an external logic controller sends a control command to start the first and second hoop motors, providing power to the positioning and adjustment dynamic component. According to the inspection requirements, the external controller drives a small gear to rotate via the first hoop motor, causing the small gear to mesh with a threaded post, moving the threaded post up and down. This adjusts the height of the sleeve and the arc-shaped toothed strip. The telescopic support ensures that the arc-shaped toothed strip rises and falls synchronously during the lifting process and remains stable. Furthermore, during the lifting and lowering of the arc-shaped toothed strip, the central drive gear and the arc-shaped toothed strip form a meshing connection, facilitating the central drive rotation... The gear drives the bearing groove rod to adjust the rotation of the rotating column, causing the connected related structures to rotate synchronously. Then, the external logic controller drives the rotating gear to rotate through the second hoop motor, causing the driving rotating gear to mesh with the rotating gear and drive the rotating gear and the collar at its bottom to rotate. The rotating gear is located outside the arc-shaped toothed column and is connected through the stator and rotor structure. When the second hoop motor drives the rotating gear, the rotating gear drives the collar to rotate synchronously, forming an orientation angle adjustment. The whole is precisely adjusted according to the real-time detection position to ensure that the subsequent frame weld seam detection components, weld seam detection sensors, prestress detection sensors and pressure blocks can cover the entire frame surface. This improves the accuracy and efficiency of detection and screening, and also forms an automated operation, ensuring quality control of the electric vehicle frame during the production process and improving detection efficiency.

[0017] By cooperating with the position weld inspection frame, the position positioning connecting block, and the motor drive box, the position weld inspection frame slides inside the top of the side sliding guide post and the drive transverse rail. Then, a dual-axis pneumatic cylinder is installed at the center end of the position weld inspection frame, causing the connecting frame to rise and fall. This facilitates the inspection of the frame by weld inspection sensors and prestress detection sensors installed at the bottom of the connecting frame. The weld inspection sensors perform a comprehensive inspection of the frame welds, detecting and recording any defects such as cracks, porosity, and slag inclusions. The prestress detection sensor detects the prestress of the frame, ensuring the safety and stability of the frame during use. Secondly, multiple sets of ultrasonic detectors perform preliminary inspection of the frame welds, quickly identifying potential problems. The detected data is then collected by sensors and transmitted to an external logic circuit. The controller analyzes and records data to ensure the quality and safety of the frame inspection. The hydraulic telescopic rod, in conjunction with the positioning connecting block, reaches a preset position and then drives the pressure block to press down on the frame. A stress sensor performs real-time monitoring of the frame, detecting the stress distribution under pressure. Then, with the assistance of an automatic marking end, when defects or abnormalities are detected, the automatic marking end marks the frame for subsequent processing. Next, the motor drive box drives the angle-rotating boom and surface X-ray detector to adjust their rotation, allowing for X-ray or other radiographic inspection of the frame surface to detect internal defects. The pulley structure and the energy-saving drive motor work together to drive the entire device to perform a rotary inspection of the frame on the external conveyor belt structures on both sides, improving inspection efficiency and comprehensiveness.

[0020] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1-7 As shown, the embodiment provides a testing system for electric vehicle frame production based on screening components, including a main testing line frame 1. Vertical linear guide rails 2 are fastened to the three side surfaces of the main testing line frame 1. The vertical linear guide rails 2 have a height difference. Positioning adjustment dynamic components 3 are slidably connected inside the vertical linear guide rails 2. The positioning and adjustment dynamic component 3 includes a displacement sliding seat 31, which is slidably connected inside the vertical linear guide rail 2. A crank frame 32 is fastened to the side of the displacement sliding seat 31. A first hoop motor 33 and a second hoop motor 37 are fastened to the side surfaces of the crank frame 32, respectively. A sleeve 35 is installed at the top side of the crank frame 32. A threaded post 36 is installed at the bottom of the sleeve 35. An arc-shaped toothed strip post 390 is installed at the bottom of the threaded post 36. The sleeve 35 drives the threaded post 36 and the arc-shaped toothed strip post 390 to form a lifting and sliding connection at the top of the crank frame 32. Rotary teeth are sleeved and connected to the outside of the arc-shaped toothed strip post 390 through a stator and rotor structure. 38. The bottom of the rotating tooth 38 is integrally formed with a collar 394. The side end of the rotating tooth 38 is meshed with a drive rotating tooth 39. The drive rotating tooth 39 is connected to the second hoop motor 37. The output end of the first hoop motor 33 is connected to a small rotating gear 34. The small rotating gear 34 and the threaded column 36 form a meshing connection. The bottom of the arc-shaped toothed column 390 is equipped with a telescopic support 391. The side of the collar 394 is fastened with a bearing groove rod 393. The inside of the bearing groove rod 393 is rotatably connected to an adjusting rotating column 392. The side end of the adjusting rotating column 392 is fastened with a central drive rotating tooth 395. The central drive rotating tooth 395 and the arc-shaped toothed column 390 form a meshing connection.

[0022] In one specific scheme, the main inspection frame 1 is installed in a suitable position, and the vertical linear guide rail 2 is securely connected to the three side surfaces of the main inspection frame 1. The positioning and adjustment dynamic component 3 is installed inside the vertical linear guide rail 2 to ensure smooth sliding. When the frames conveyed on the conveyor belts on both sides are inspected and screened, the external logic controller sends a control command to start the first hoop motor 33 and the second hoop motor 37 to provide power to the positioning and adjustment dynamic component 3. According to the inspection requirements, the external controller drives the small rotating gear 34 to rotate through the first hoop motor 33, so that the small rotating gear 34 meshes with the threaded column 36, driving the threaded column 36 to move up and down, thereby adjusting the height of the sleeve 35 and the arc-shaped toothed bar 390. The telescopic support 391 ensures that the arc-shaped toothed bar 390 rises and falls synchronously during the lifting and lowering process and remains stable. When the arc-shaped toothed bar 390 rises and falls, the central drive rotating gear 395 and the arc-shaped toothed bar 390 are connected. The bar posts 390 form an engaging connection, facilitating the drive gear 395 to drive the bearing groove rod 393 to adjust the rotation of the rotating post 392, so that the connected related structures rotate synchronously. Then, the external logic controller drives the drive gear 39 to rotate through the second hoop motor 37, so that the drive gear 39 meshes with the gear 38, driving the gear 38 and its bottom collar 394 to rotate. The gear 38 is located outside the arc-shaped toothed bar post 390 and is connected through the stator and rotor structure, so that when the second hoop motor 37 drives, the gear 38 drives the collar 394 to rotate synchronously, forming an orientation angle adjustment. The whole is precisely adjusted according to the real-time detection position, ensuring that the subsequent frame weld seam detection component 4, weld seam detection sensor 48, prestress detection sensor 47 and pressure block 11 can cover the entire frame surface, improving the accuracy and efficiency of detection and screening, and forming an automated operation, ensuring the quality control of the electric vehicle frame in the production process and improving detection efficiency.

[0024] The frame weld inspection assembly 4 includes a sliding guide post 41, and the side end of the sliding guide post 41 is mounted with a drive transverse rail 42 via a connecting plate.

[0025] Multiple sets of ultrasonic detectors 43 are installed at the bottom of the sliding guide post 41 and the drive transverse rail 42, and a position weld detection frame 44 is slidably connected inside the top of the sliding guide post 41 and the drive transverse rail 42.

[0026] A dual-axis pneumatic cylinder 45 is installed at the center end of the position weld inspection frame 44, and a connecting frame 46 is installed at the bottom of the dual-axis pneumatic cylinder 45. A weld inspection sensor 48 and a prestress inspection sensor 47 are respectively installed at the bottom of the connecting frame 46.

[0027] In one specific embodiment, a drive transverse rail 42 is mounted on the side end of the sliding guide post 41 via a connecting plate. Multiple ultrasonic detectors 43 are installed at the bottom of the sliding guide post 41 and the drive transverse rail 42 for preliminary inspection of the frame weld quality. Then, when the aforementioned positioning and adjustment dynamic component 3 drives the frame weld inspection component 4 to adjust, the position weld inspection frame 44 slides within the top of the sliding guide post 41 and the drive transverse rail 42. Next, a dual-axis pneumatic cylinder 45 is installed at the center end of the position weld inspection frame 44, causing the dual-axis pneumatic cylinder 45 to drive the connecting frame component 46 to achieve lifting and adjustment, facilitating the connection frame... The weld inspection sensor 48 and the prestress inspection sensor 47 installed at the bottom of component 46 respectively inspect the frame. The weld inspection sensor 48 performs a comprehensive inspection of the frame welds, discovers and records any defects such as cracks, porosity, and slag inclusions. The prestress inspection sensor 47 detects the prestress of the frame to ensure the safety and stability of the frame during use. Secondly, multiple ultrasonic detectors 43 perform preliminary inspection of the frame welds to quickly identify potential problems. Afterwards, the detected data is collected by the sensors and transmitted to an external logic controller for analysis and recording to ensure the quality and safety of the frame inspection.

[0033] In one specific scheme, when the aforementioned positioning and adjustment dynamic component 3 is driven for adjustment, the hydraulic telescopic rod 9, in cooperation with the position positioning connecting block 8, reaches the preset position. After reaching the preset position, the hydraulic telescopic rod 9 drives the pressure block 11 to press down on the frame. The frame is then monitored in real time by a stress sensor to detect the stress distribution of the frame under pressure. Subsequently, with the cooperation of the automatic marking end 10, when a defect or abnormality is detected, the automatic marking end 10 will mark the frame for subsequent processing. Next, the motor drive box 5 drives the angle rotation arm 6 and the surface X-ray detector 7 to adjust and rotate, which is used to perform X-ray or other X-ray inspection on the surface of the frame to detect internal defects. With the cooperation of the pulley structure 12 and the drive energy-saving motor 13, the entire device is driven to perform a rotary inspection of the frame on the surface of the external conveyor belt structure on both sides, improving the inspection efficiency and comprehensiveness.

The height of the bar column 390 is determined by the telescopic support 391, which ensures that the arc-shaped toothed bar column 390 rises and falls synchronously during the lifting process and remains stable. During the lifting and lowering of the arc-shaped toothed bar column 390, the central drive tooth 395 and the arc-shaped toothed bar column 390 engage, facilitating the central drive tooth 395 to drive the bearing groove rod 393 to adjust the rotation of the rotating column 392, causing the connected related structures to rotate synchronously.
