[0001] The present application relates to the field of frame welding precision detection, in particular to an electric motorcycle frame welding precision detection device and method. BACKGROUND

[0002] In the production and manufacturing process of electric motorcycle frames, welding is a key link, and the quality of welding directly affects the structural strength, overall performance of the electric motorcycle frame and the accuracy of assembly with other parts.

[0003] Referring to the accompanying drawings Figure 11 As shown, the detection device we use currently has some limitations in detecting the welding precision of electric motorcycle frames. Electric motorcycle frames have diversified shapes and sizes, but traditional detection devices can usually only adapt to specific models or sizes of electric motorcycle frames, and cannot flexibly adapt to the detection needs of electric motorcycle frames of multiple models and sizes, resulting in the need to invest in different detection devices during production, increasing production costs; in addition, the traditional detection device needs to hoist the welded electric motorcycle frame into the detection device, manually position it, and then detect the calibration hole of the welded part one by one, resulting in detection errors and low efficiency. SUMMARY

[0086] Positioning device 7 is installed on the track 3 or the mounting frame 2 near the second end.

[0087] The detection device includes the following components:

[0088] Demountable mounting frame 2: This is a frame structure that can be easily assembled and disassembled.

[0089] Track 3: Fixed to the bottom of the mounting frame 2, track 3 is used to transport the welded electric motorcycle frame 1 into the mounting frame 2 of the testing device, avoiding the need for manual operation of hoisting equipment to transport and place the electric motorcycle frame 1. The first end of track 3 is connected to the welding line of the electric motorcycle frame 1, and the second end is connected to the finished product conveyor line of the electric motorcycle frame 1.

[0090] Side inspection components 4: Multiple side inspection components 4 are slidably installed between the upper and lower longitudinal beams on both sides of the mounting frame 2. These side inspection components 4 can move along the direction of the electric motorcycle frame 1 to inspect the side accuracy of the welded electric motorcycle frame 1.

[0091] Top Inspection Component 5: Top inspection component 5 is slidably installed between the two longitudinal beams at the upper end of the mounting frame 2. This component is used to inspect the welding accuracy of the front handlebars of the electric motorcycle frame 1.

[0092] Conveyor unit 6: Located on track 3, it is used to transport the welded electric motorcycle frame 1. It is understood that conveyor unit 6 can also be used during the welding process of the electric motorcycle frame 1. Conveyor unit 6 can move along track 3, transporting the electric motorcycle frame 1 from the welding work line to the mounting frame 2 of the testing device.

[0093] Positioning device 7: A positioning device 7 is installed on the track 3 or the mounting frame 2 near the second end. This device is used to accurately position the electric motorcycle frame 1, ensuring that the electric motorcycle frame 1 is correctly positioned within the mounting frame 2.

[0094] By combining the above components, the welding accuracy testing device for the electric motorcycle frame 1 can detect the welding accuracy of the side and top of the electric motorcycle frame 1. The side detection component 4 can detect the side welding while moving along the direction of the electric motorcycle frame 1, while the top detection component 5 can detect the welding accuracy of the handlebars of the electric motorcycle frame 1. The conveyor group 6 is responsible for transporting the welded electric motorcycle frame 1 from the welding line to the mounting frame 2 of the testing device. After the inspection is completed, it is transported to the finished product conveyor line. The positioning device 7 is used to ensure the accurate positioning of the electric motorcycle frame 1 within the mounting frame 2. Example 2

[0095] Furthermore, refer to Figure 5 , Figure 6 As shown, the side detection component 4 includes:

[0096] The sliding column 41 is slidably installed at both ends between the upper and lower longitudinal beams on the common vertical plane of the mounting frame 2.

[0097] A universal base 42 that is slidably mounted on a sliding column 41 and can be fixed in any position; and

[0098] A telescopic component 43 is fixed on the universal base 42, and a detection column 44 is installed at one end of the telescopic component 43 near the electric motorcycle frame 1.

[0099] Side inspection component 4 includes a sliding column 41, a universal base 42, and a telescopic component 43. The two ends of the sliding column 41 are slidably installed between the upper and lower longitudinal beams on the common vertical plane of the mounting frame 2 to provide lateral sliding adjustment. It can be fixed at any position. Various fixing methods are available, commonly including pre-tightening and fastening, but specific structural limitations are not specified here. The universal base 42 is slidably installed on the sliding column 41 and can be fixed at any position, providing vertical and tilt adjustment. It is suitable for precision inspection of welded parts at different heights and angles. Similar to the fixing principle of the sliding column 41, the universal base 42 can also be fixed in various ways, such as snap-fitting or bolt tightening, but specific structural limitations are not specified here. The telescopic component 43 is fixed to the universal base 42, and an inspection column 44 is installed at the end closest to the electric motorcycle frame 1. The telescopic component 43 drives the inspection column 44 to extend and retract to inspect the hole precision of the welded parts. The welding precision of the side of the electric motorcycle frame 1 is determined based on the inspected precision of the calibrated holes in the welded parts.

[0100] Understandably, the position of the sliding column 41 can be adjusted according to the height of the welded parts of the electric motorcycle frame 1. The universal base 42 can be adjusted horizontally and vertically on the sliding column 41 to accommodate the electric motorcycle frame 1 at different positions and angles. The telescopic assembly 43 is fixed to the universal base 42, and a detection column 44 is installed on the end of the telescopic assembly 43 near the end of the electric motorcycle frame 1 to detect the accuracy of the side welding of the electric motorcycle frame 1.

[0101] The shape and size of the detection column 44 vary and can be set according to the calibration hole diameter and number of the welded parts. Example 3

[0102] Furthermore, refer to Figure 6 As shown, the distinguishing features between the top detection component 5 and the side detection component 4 are as follows:

[0103] The sliding beam 51 replaces the sliding column 41, and the sliding beam 51 is slidably installed between the two upper crossbeams of the mounting frame 2.

[0104] Understandably, the top detection component 5 has a similar structure to the side detection component 4; the installation position of the sliding beam 51 can be adjusted according to the length of the electric motorcycle frame 1, that is, it can be adjusted according to the position of the handlebars of the electric motorcycle frame 1. The sliding beam 51 is slidably installed between the two upper crossbeams of the mounting frame 2, and this installation method provides convenient adjustment and positioning functions for the top detection component 5.

[0105] The top inspection assembly 5 also includes a universal base 42 slidably mounted on the sliding beam 51, a telescopic assembly 43 fixed on the universal base 42, and an inspection post 44 installed on the telescopic assembly 43 near the end of the electric motorcycle frame 1. The top inspection assembly 5 is used to inspect the welding accuracy of the handlebars of the electric motorcycle frame 1 after welding.

[0106] The top detection component 5 is installed near one end of the handlebars of the electric motorcycle frame 1 to accurately measure the welding precision of the handlebars. This position can be adjusted according to the specific frame model to accommodate different types and sizes of electric motorcycle frames 1.

[0107] The top inspection component 5 and the side inspection component 4 together constitute a complete welding accuracy inspection device for the electric motorcycle frame 1. By combining the installation method of the sliding beam 51, the top inspection component 5 can more flexibly adapt to different types and sizes of electric motorcycle frames 1, achieving accurate inspection and adjustment of welding accuracy. This design can improve the accuracy and efficiency of welding quality control. Example 4

[0108] Furthermore, refer to Figure 7 As shown, the universal base 42 includes:

[0109] Sleeve 421, on which a hinge seat 4211 is provided;

[0110] The connector 422 is hinged to the hinge seat 4211; and

[0111] The corner plate 423, which is mounted on the end of the connector 422 away from the hinge seat 4211, is rotated, and the telescopic component 43 is fixed on the corner plate 423.

[0112] In this specific embodiment, the universal base 42 is used to support and adjust the side detection component 4 to accommodate the electric motorcycle frame 1 at different positions and angles. The specific implementation is as follows:

[0113] Sleeve 421 is a tubular or cylindrical part with a hinge seat 4211 on it. Sleeve 421 can be connected to other components through the hinge seat 4211 to achieve flexible adjustment and rotation.

[0114] Connector 422 is hinged to hinge seat 4211, providing support and movement for sleeve 421 and other components. Connector 422 can be a link or other suitable structure, and if necessary, connector 422 can also be telescopic to accommodate the inspection of welded parts at different depths.

[0115] Angle plate 423 is a plate-shaped part that is rotatably mounted on one end of connector 422, away from hinge seat 4211, and can be fixed after being rotated to any desired position. Angle plate 423 has a rotating function, and its position and angle can be adjusted as needed. Telescopic assembly 43 is fixed to angle plate 423 for inspection operations on electric motorcycle frame 1.

[0116] The design of the universal base 42 allows the side detection component 4 to be adjusted in multiple directions, both horizontally and vertically. By adjusting the position and angle of the sleeve 421, connector 422, and corner plate 423, accurate detection of the side of the electric motorcycle frame 1 can be achieved.

[0117] In practice, the positions and angles of the sleeve 421, connector 422, and corner plate 423 are adjusted according to the specific shape and size of the electric motorcycle frame 1, so that the side inspection component 4 can be accurately positioned at the orthographic projection position of the calibration hole at the welding part of the electric motorcycle frame 1. By using a suitable inspection post 44, the inspection and evaluation of the welding accuracy of the side of the electric motorcycle frame 1 can be achieved. Example 5

[0118] Furthermore, refer to Figure 8 As shown, the sleeve 421 is provided with a sliding groove 4212, and one end of the hinge seat 4211 is slidably installed in the sliding groove 4212.

[0119] In this embodiment, to enhance the fixing stability of the connector 422, the hinge seat 4211 is designed to be detachable, which can press the connector 422 and provide a more stable fixing method. The specific implementation is as follows:

[0120] One of the hinge lugs of the hinge seat 4211 is a part that is connected to the sleeve 421. One end of the hinge seat 4211 is slidably mounted on the sleeve 421 via a groove 4212 on the sleeve 421.

[0121] The connector 422 is a key component that connects to the sleeve 421 via a connection to the hinge seat 4211. One end of the connector 422 is fixedly connected to the hinge seat 4211, and the other end is connected to the angle plate 423. Supported by the hinge seat 4211, the connector 422 can rotate horizontally, and after rotating to a set position, it is fixed by pressing the sliding hinge lug. Furthermore, the sliding hinge lug can accommodate connectors 422 of different sizes, ensuring high compatibility for replacement parts when necessary.

[0122] The detachable connector is designed to separate and clamp the connector 422 to provide a more stable fixation. The detachable connector can be a clamping device, a screw fastener, or other suitable mechanical structure used to ensure the strength and stability of the connection by pressing the connector 422.

[0123] By employing a split-type connector, a more stable fixing method can be provided through adjustment and clamping of the connector 422. This helps ensure that the connector 422 does not loosen or become misaligned during use, thereby improving the accuracy and reliability of the test. Example 6

[0124] To go further, refer to Figure 7 , Figure 8 As shown, the telescopic component 43 includes:

[0125] The first cylinder 431 fixed on the angle plate 423; and

[0126] A sliding connecting seat 432 is installed at the telescopic end of the first cylinder 431. A pressure sensing device 433 is installed inside the sliding connecting seat 432. A detection column 44 is fixed on the side of the sliding connecting seat 432 away from the first cylinder 431.

[0127] In this embodiment, the telescopic assembly 43 is designed to achieve precise control and adjustment of the detection column 44 by using a cylinder and a sliding connecting seat 432. The specific implementation is as follows:

[0128] The telescopic assembly 43 includes a first cylinder 431, which is fixed to the corner plate 423. The movement of the telescopic rod of the first cylinder 431 drives the detection column 44 to telescopically move to pass into the calibration hole on the weldment. When resistance is encountered, i.e., a welding deviation occurs, the sliding connecting seat 432 is squeezed after encountering resistance, triggering the pressure sensing device 433 to work and record the welding position of the deviation.

[0129] The pressure sensing device 433 here includes, but is not limited to:

[0130] Strain gauge sensor: A strain gauge sensor is a device that measures the strain changes caused by force on an object. It can accurately measure the compressive force between mechanical parts. The strain gauge sensor senses strain by detecting changes in the resistance of the strain gauge and converts this into an electrical signal output. The magnitude of the compressive force is determined by measuring the change in resistance value.

[0131] Pressure sensors: While pressure sensors are typically used to measure the pressure of liquids or gases, they can also be used in certain situations to measure the compressive force between mechanical parts. By using appropriate contact devices or clamps, pressure sensors are mounted between mechanical parts to enable the measurement of compressive force.

[0132] Force sensor: A force sensor is a device that can measure the force acting on an object, and can be used to measure the compressive force between mechanical parts. Force sensors can sense the force through principles such as resistance strain, electromagnetic induction, or piezoelectric effect, and convert it into an electrical signal output.

[0133] Pressure probe: A pressure probe is a probe device that directly contacts mechanical parts to measure the pressure exerted on their surfaces. By placing the pressure probe between mechanical parts, the value of the compressive force can be measured and recorded.

[0134] These pressure sensing devices 433 can be selected according to specific needs, choosing appropriate types and specifications. When selecting a device, factors such as measurement range, accuracy requirements, reliability, and compatibility with the measured part must be considered. Simultaneously, it should be ensured that the installation and use of the device meet the requirements of the actual application, and calibration and verification should be performed to ensure accurate measurement of extrusion pressure.

[0135] A sliding connecting seat 432 is installed at the telescopic end of the first cylinder 431. A pressure sensing device 433 is installed inside the sliding connecting seat 432 to measure the magnitude of the extrusion force. The pressure sensing device 433 can be a sensor or other suitable device for accurately detecting and recording the extrusion force between the detection post 44 and the calibration hole at the deviation welding position.

[0136] The detection post 44 is fixed on the sliding connecting seat 432, on the side away from the first cylinder 431. Located on one side of the sliding connecting seat 432, the detection post 44 can extend into the calibration hole of the electric motorcycle frame 1 welded component. By measuring the magnitude of the extrusion force, the accuracy and quality of the side welding of the electric motorcycle frame 1 can be evaluated.

[0137] This design enables the telescopic component 43 to precisely control and adjust the position of the detection column 44 and monitor the extrusion pressure, thereby achieving effective detection of the welding accuracy of the side of the electric motorcycle frame 1. Example 7

[0138] Furthermore, refer to Figure 8 As shown, the sliding connector 432 includes:

[0139] A connecting plate 4321 is fixed to the telescopic end of the first cylinder 431, and multiple sliding pins 4322 are provided on the connecting plate 4321.

[0140] A mounting plate 4323 is slidably connected to multiple sliding columns 4322, and a pressure sensing device 433 is installed between a connecting plate 4321 and a mounting plate 4323; and

[0141] Multiple springs 4324 are respectively fitted on multiple sliding pillars 4322 and located between the connecting plate 4321 and the mounting plate 4323.

[0142] In this embodiment, the sliding connector 432 is designed to provide a more stable fixing method and pressure detection function. The specific implementation is as follows:

[0143] The sliding connecting seat 432 includes a connecting plate 4321, which is fixed to the telescopic end of the first cylinder 431. Multiple sliding posts 4322 are provided on the connecting plate 4321, and the mounting plate 4323 is connected to the connecting plate 4321 via these sliding posts 4322. The number of sliding posts 4322 can be adjusted as needed to ensure a stable connection and support.

[0144] Mounting plate 4323 is slidably connected to multiple sliding columns 4322, providing support and fixation. A pressure sensor 433 is installed between connecting plate 4321 and mounting plate 4323 to measure the magnitude of the compressive force. Located between connecting plate 4321 and mounting plate 4323, pressure sensor 433 can accurately measure the pressure between mechanical parts.

[0145] Multiple springs 4324 are fitted onto multiple sliding columns 4322, and these springs 4324 are located between the connecting plate 4321 and the mounting plate 4323. The function of the springs 4324 is to provide appropriate pressure and elastic support to ensure the stability and reliability of the sliding connecting seat 432 under different working conditions.

[0146] Through the above design, the sliding connector 432 can achieve a stable fixation between the connecting plate 4321 and the mounting plate 4323, while the multiple sliding columns 4322 and the sleeved springs 4324 can provide sufficient support and pressure detection functions. At the same time, the installation position of the pressure sensor 433 can accurately measure the extrusion pressure between mechanical parts to evaluate welding quality and adjust process parameters. Example 8

[0147] Furthermore, refer to Figure 9 As shown, the positioning device 7 includes:

[0148] Slide rail 71;

[0149] A sliding seat 72 is slidably installed inside the slide rail 71;

[0150] The lead screw 73 is threadedly connected to the sliding seat 72, and the two ends of the lead screw 73 are rotatably connected to the two ends of the slide rail 71 respectively;

[0151] The second cylinder 74 is mounted on the sliding seat 72; and

[0152] The abutment block 75 is installed at the telescopic end of the second cylinder 74. The abutment block 75 has an abutment notch 751 for blocking the wheel, and the abutment block 75 is magnetic.

[0153] In this embodiment, the positioning device 7 is designed to achieve accurate positioning and stable fixation of the electric motorcycle frame 1. The specific implementation is as follows:

[0154] The positioning device 7 includes a slide rail 71 and a sliding seat 72 slidably mounted within the slide rail 71 to provide smooth sliding movement. The design of the slide rail 71 allows the sliding seat 72 to move horizontally within it to achieve positioning adjustment.

[0155] The sliding seat 72 is connected to the lead screw 73 by a thread, and the two ends of the lead screw 73 are rotatably connected to the two ends of the slide rail 71. By rotating the lead screw 73, the position of the sliding seat 72 on the slide rail 71 can be adjusted, thereby achieving precise positioning of the electric motorcycle frame 1.

[0156] The positioning device 7 also includes a second cylinder 74 mounted on the sliding seat 72. The second cylinder 74 is connected to the abutment block 75 via a telescopic end. The abutment block 75 is provided with an abutment notch 751 for blocking the wheels, the shape and size of which are adapted to the wheels of the transport vehicle assembly 6.

[0157] The contact block 75 is magnetic, which provides additional stability and attraction when the contact notch 751 comes into contact with the wheels of the conveyor assembly 6, further ensuring the accuracy and fixation of the positioning.

[0158] Through the above design, the positioning device 7 can slide smoothly on the slide rail 71, and the sliding seat 72 can be accurately adjusted and positioned by rotating the lead screw 73. The installation of the second cylinder 74 and the abutment block 75 can resist the wheels of the conveyor assembly 6, and provide additional stability and fixing force through magnetism.

[0159] The design of this specific embodiment enables the positioning device 7 to achieve precise positioning and stable fixation of the electric motorcycle frame 1, so as to detect the welding accuracy.

[0160] It should be noted that the conveyor group 6 can be powered, that is, a drive source that can drive the conveyor group 6 to move. When the conveyor group 6 has a drive source, the contact block 75 needs to be magnetic. In addition, if the track 3 is set at a certain angle, the conveyor group 6 may not be powered. In this case, the contact block 75 does not necessarily need to be magnetic, but the magnetism can attract the conveyor group 6, thereby making the electric motorcycle frame 1 more stable. Example 9

[0161] Furthermore, refer to Figure 4 As shown, the transport vehicle group 6 includes:

[0162] The rear wheel assembly 61 is used to support the main body of the electric motorcycle frame 1, and a support pad 62 is installed on the rear wheel assembly 61; and

[0163] The front wheel assembly 63 is used to support the handlebars of the electric motorcycle frame 1, and the front wheel assembly 63 is equipped with a height-adjustable support device 64.

[0164] In this embodiment, the transport vehicle 6 is designed to provide stable support and adjustable height for the electric motorcycle frame 1. The specific implementation is as follows:

[0165] The rear wheel assembly 61 supports the main body of the electric motorcycle frame 1. It consists of one or more support pads 62, which are mounted on the rear wheel assembly 61 to provide stable support for the electric motorcycle frame 1. Understandably, the support pads 62 vary in shape and size and can be selected according to the model of the electric motorcycle frame 1. The support pads 62 can be installed and removed from the rear wheel assembly 61. The support pads 62 can have appropriate hardness to ensure that the contact area and pressure distribution with the electric motorcycle frame 1 are adapted without damaging the electric motorcycle frame 1.

[0166] The front wheel assembly 63 supports the handlebars of the electric motorcycle frame 1. It includes one or more support devices 64 mounted on the front wheel assembly 63 and has height adjustment functionality. By adjusting the height of the support devices 64, it can accommodate variations in the handlebar height of different electric motorcycle frames 1, achieving accurate support and balance.

[0167] Through the above design, the transport unit 6 provides stable support for the main body and handlebars of the electric motorcycle frame 1. The support pad 62 of the rear wheel assembly 61 and the height adjustment support device 64 of the front wheel assembly 63 can adapt to different sizes and shapes of the electric motorcycle frame 1, ensuring stability and balance.

[0168] The design of this specific embodiment enables the transport vehicle group 6 to stably transport and support the electric motorcycle frame 1 during the welding process and the process of checking the welding accuracy. Example 10

[0169] In this embodiment, reference Figure 10 As shown, a testing method for an electric motorcycle frame welding accuracy testing device is provided, comprising the following steps:

[0170] Step S1: Place the electric motorcycle frame 1 on the conveyor group 6 and weld the parts that need to be welded;

[0171] Step S2: Adjust the side detection component 4, the top detection component 5 and the positioning device 7 to suit the welded electric motorcycle frame 1, and activate the positioning device 7 to extend and retract onto the track 3.

[0172] Step S3: The welded electric motorcycle frame 1 is transported to the mounting frame 2 of the testing device, and the positioning device 7 blocks the transport vehicle group 6 to achieve positioning of the electric motorcycle frame 1.

[0173] Step S4: Activate the side detection component 4 and the top detection component 5;

[0174] Step S5: Compare the data from the pressure sensor 433 with the preset data. If the data from the pressure sensor 433 is less than the preset data, the welding accuracy is qualified.

[0175] Step S6: Record the location of the pressure sensor 433 that is abnormal, indicating that the welding accuracy of the electric motorcycle frame 1 at that location is unqualified.

[0176] Place the electric motorcycle frame 1 on the conveyor assembly 6, and install the parts to be welded onto the electric motorcycle frame 1. Ensure the position and orientation of the parts to be welded are accurate.

[0177] The side inspection assembly 4, top inspection assembly 5, and positioning device 7 are adjusted to fit the welded electric motorcycle frame 1. The side inspection assembly 4, through adjustment of the sliding column 41, universal base 42, and telescopic assembly 43, moves the inspection column 44 closer to and extends into the calibration hole of the side welded part of the electric motorcycle frame 1 to inspect its welding accuracy. Simultaneously, the top inspection assembly 5, through adjustment of the sliding beam 51, universal base 42, and telescopic assembly 43, inspects the welding accuracy of the handlebars.

[0178] The positioning device 7 is activated, extending and retracting onto the track 3 to ensure accurate positioning of the conveyor assembly 6 and the welded components. The positioning device 7 achieves accurate positioning of the electric motorcycle frame 1 by blocking the movement of the conveyor assembly 6, ensuring the accuracy of the welding position to be inspected.

[0179] The side inspection component 4 and the top inspection component 5 are activated to begin inspecting the welded electric motorcycle frame 1. The side inspection component 4 and the top inspection component 5 will inspect and record the accuracy of each welded part of the electric motorcycle frame 1.

[0180] The data from pressure sensor 433 is compared with preset data. If the data from pressure sensor 433 is less than the preset data, the welding accuracy is acceptable. When pressure sensor 433 detects abnormal data, the location of the abnormal data is recorded. This location indicates the area where the welding accuracy of the electric motorcycle frame 1 is unacceptable and needs to be repaired or adjusted.

[0181] Through the above steps, the detection method in this embodiment can detect and evaluate the welding accuracy of the electric motorcycle frame 1. Adjustments to the side detection component 4 and the top detection component 5 ensure coverage of the entire welding area, while the use of the positioning device 7 enables accurate positioning of the electric motorcycle frame 1. Recording abnormal data helps identify locations where welding accuracy is substandard, allowing for subsequent corrective measures.

[0182] The beneficial effects of the present invention are specifically reflected in the fact that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
