The detection mechanism 30 includes a fixed frame 301, a mounting frame 302 and a telescopic assembly. The fixed frame 301 and the mounting frame 302 are provided in parallel on the mounting seat 20, and the mounting frame 302 is located outside the fixed frame 301. A positioning plate 303 is detachably provided in the fixed frame 301. A plurality of positioning holes 3031 corresponding to the holes of the motorcycle frame are provided on the positioning plate 303 along the width direction of the base 10. The mounting frame 302 is provided with a telescopic assembly. A plurality of mounting blocks 307 capable of sliding in a vertical direction and in a length direction of the base 10 are provided, and positioning shafts 304 capable of sliding in a width direction of the base 10 are provided on the plurality of mounting blocks 307. The ends of the plurality of positioning shafts 304 close to the fixed frame 301 are coaxially connected with a detection head 305 through a telescopic assembly. The detection head 305 can be driven to slide in the width direction of the base 10 by adjusting the telescopic assembly, and the positioning shaft 304 can coaxially penetrate the positioning hole 3031 to allow the detection head 305 to be located on the inner side of the fixed frame 301.

[0039] In the above embodiment, the mounting block 307 is slid along the vertical direction and the length direction of the base 10 to make the positioning shaft 304 correspond to the positioning hole 3031, and then the positioning shaft 304 is slid along the width direction of the base 10 to make the positioning shaft 304 drive the detection head 305 to pass through the positioning hole 3031, so that the detection head 305 can be coaxial with the positioning hole 3031, so that the detection head 305 corresponds to the hole position of the motorcycle frame, and the position of the detection head 305 is convenient and labor-saving to adjust the position of the detection head 305, and the detection head 305 can be positioned, thereby improving the corresponding accuracy of the detection head 305 and the hole position of the motorcycle frame. The driving component drives the two groups of mounting seats 20 to move relatively close to each other.

The detection is convenient and quick, and the detection head 305 is driven to slide along the width direction of the base 10 by adjusting the telescopic component. The detection head 305 slides in the direction of 10 degrees of the width of the base to adjust the distance between the detection head 305 and the corresponding hole, which is convenient for detecting the holes that are not in the same vertical plane at the same time, thereby improving the practicality of the device.

[0040] Please also read Figure 4 and Figure 5 Specifically in the above embodiment, the detection mechanism 30 also includes a mounting rod 306, and the mounting frame 302 is provided with a through second through slot 3021 along the width direction of the base 10, and first limiting slots 3022 are provided on both sides of the second through slot 3021.

By applying force to the mounting block 307 in the vertical direction and the length direction of the base 10, the mounting block 307 can drive the positioning shaft 304 to move in the vertical direction and the length direction of the base 10, so that the positioning shaft 304 corresponds to the positioning hole 3031, and by sliding the positioning shaft 304 along the width direction of the base 10 so that the positioning shaft 304 passes through the positioning hole 3031, the movement of the positioning shaft 304 in the vertical direction and the length direction of the base 10 can be restricted, thereby limiting the movement of the positioning shaft 304 in the vertical direction and the length direction of the base 10.

[0041] See also Figure 2 and Figure 3In one embodiment, the driving assembly includes a double-output shaft motor 201 and a first screw 202; a first guide groove 101 is opened at the top of the base 10, and a first guide block 203 is arranged at the bottom of the two groups of mounting seats 20. The two groups of first guide blocks 203 are slidably arranged in the first guide groove 101 along the width direction of the base 10. The double-output shaft motor 201 is arranged in the first guide groove 101, and the output shafts at both ends are coaxially connected with the first screw 202 parallel to the first guide groove 101. The spiral directions of the two groups of first screws 202 are opposite, and they are respectively threadedly connected to the two groups of first guide blocks 203.

[0042] In the above embodiment, by controlling the double-output shaft motor 201 to drive the two groups of first screws 202 to rotate and cooperate with the two groups of first guide blocks 203 threads, the two groups of first guide blocks 203 can be driven to drive the two groups of mounting seats 20 to move relatively close to each other. By controlling the double-output shaft motor 201 to drive the two groups of first screws 202 to reverse and cooperate with the two groups of first guide blocks 203 threads, the two groups of first guide blocks 203 can be driven to drive the two groups of mounting seats 20 to move relatively away from each other. It is convenient to drive the two groups of mounting seats 20 to move relatively close to or away from each other.

[0043] See also Figures 2 to 4 In one embodiment, the fixing frame 301 is provided with a first through slot 3011 along the width direction of the base 10, and a slot 3012 connected to the first through slot 3011 is provided at the top of the fixing frame 301 along the vertical direction, and the positioning plate 303 passes through the slot 3012 and is placed in the first through slot 3011.

[0044] In the above embodiment, the positioning plate 303 can be removed from the fixing frame 301 by moving the positioning plate 303 upwards, and the positioning plate 303 is easy to install and remove, and different positioning plates 303 can be replaced according to different models of motorcycle frames, thereby improving the practicality of the device.

[0045] See also Figure 3 , Figure 5 and Figure 6In one embodiment, the detection mechanism 30 also includes a positioning component, which includes a first spring 3072 and a positioning ball pin 3073. A through hole 3071 is provided on the mounting block 307. The positioning shaft 304 slides through the through hole 3071 along the width direction of the base 10. A mounting hole 3074 is provided on the circumference of the through hole 3071. One end of the positioning ball pin 3073 is penetrated into the mounting hole 3074 and is connected to the end wall of the mounting hole 3074 through the first spring 3072. A first limiting hole 3041 is provided on the circumference of the end of the positioning shaft 304 close to the fixed frame 301, and a second limiting hole 3042 is provided on the circumference of the end of the positioning shaft 304 away from the fixed frame 301. When the positioning shaft 304 is located outside the fixed frame 301, the positioning ball pin 3073 can be clamped in the first limiting hole 3041. When the positioning shaft 304 passes through the positioning hole 3031, the positioning ball pin 3073 can be clamped in the second limiting hole 3042.

[0046] In the above embodiment, by making the positioning ball pin 3073 respectively clamped in the first limit hole 3041 and the second limit hole 3042, the positioning shaft 304 can be positioned when the positioning shaft 304 is located outside the fixed frame 301 and the positioning shaft 304 passes through the positioning hole 3031. This can avoid the phenomenon that the mounting seat 20 drives the fixed frame 301 and the mounting frame 302 to move and cause the positioning shaft 304 to slide, thereby preventing the detection head 305 from colliding with the positioning plate 303 when not in use, and preventing the positioning shaft 304 from withdrawing from the positioning hole 3031 when the detection head 305 is in use.

[0047] Specifically in the above embodiment, a third limiting groove 3044 is provided on the periphery of the positioning shaft 304, a second limiting block 3076 is provided on the periphery of the through hole 3071, and the second limiting block 3076 is slidably disposed in the third limiting groove 3044 along the width direction of the base 10. The third limiting groove 3044 cooperates with the second limiting block 3076 to avoid the rotation of the positioning shaft 304 when sliding along the width direction of the base 10, thereby facilitating the positioning ball pin 3073 to be clamped in the first limiting hole 3041 or the second limiting hole 3042.

[0048] See also Figure 2 , Figure 3 and Figure 5 In one embodiment, the telescopic assembly includes a telescopic shaft 308 and a second screw 309; a telescopic hole 3043 is coaxially opened at the end of the positioning shaft 304 close to the fixed frame 301, one end of the telescopic shaft 308 is coaxially inserted into the telescopic hole 3043, and the other end is coaxially connected to the detection head 305, and the second screw 309 is coaxially rotatably arranged on the positioning shaft 304, and one end extends into the telescopic hole 3043 and is threadedly connected to the telescopic shaft 308.

[0049] In the above embodiment, the telescopic shaft 308 with the detection head 305 can be driven to move by rotating the second screw 309 and engaging with the telescopic shaft 308 thread. The movement of the detection head 305 can reduce the distance between the detection head 305 and the corresponding hole position. The telescopic shaft 308 with the detection head 305 can be driven to move in the opposite direction by rotating the second screw 309 and engaging with the telescopic shaft 308 thread in the opposite direction. The movement of the detection head 305 in the opposite direction can increase the distance between the detection head 305 and the corresponding hole position. It is convenient to adjust the distance between the detection head 305 and the corresponding hole position.

[0050] Specifically in the above embodiment, a fourth limiting groove 3045 is provided around the telescopic hole 3043, and a third limiting block 3081 is provided around the telescopic shaft 308. The third limiting block 3081 is slidably disposed in the fourth limiting groove 3045 along the width direction of the base 10. The fourth limiting groove 3045 cooperates with the third limiting block 3081 to avoid the phenomenon of rotation when the telescopic shaft 308 slides.

[0051] See also Figure 1 , Figure 2 and Figure 7 In one embodiment, the fixing mechanism includes a clamping mechanism, and the top ends of both ends of the base 10 are provided with a clamping mechanism, and the clamping mechanism includes a bottom plate 40, a support plate 401, a clamping plate 402 and a transmission assembly. The bottom plate 40 is arranged at the top end of the base 10, and the support plate 401 can be slidably arranged at the top end of the bottom plate 40 in a vertical direction. A plurality of groups of second springs 4031 are arranged between the support plate 401 and the bottom plate 40, and the plurality of groups of second springs 4031 are used to provide an upward thrust to the support plate 401. A back plate 404 is arranged on the outer side of the bottom plate 40, and two groups of clamping plates 402 that can slide along the width direction of the base 10 are relatively arranged on the back plate 404. The two groups of clamping plates 402 are located above the support plate 401, and the transmission assembly connects the support plate 401 and the two groups of clamping plates 402. When the support plate 401 moves downward, the two groups of clamping plates 402 can be driven to move relatively close to each other through the transmission assembly, and when the support plate 401 moves upward, the two groups of clamping plates 402 can be driven to move relatively far away from each other through the transmission assembly.

[0052] In the above embodiment, by placing the two ends of the motorcycle frame on the support plate 401 respectively, the motorcycle frame drives the support plate 401 to move downward due to gravity and causes the second spring 4031 to be compressed and contracted. The support plate 401 moves downward and can drive the two groups of clamping plates 402 to move relatively close to each other through the transmission component. The two groups of clamping plates 402 move relatively close to each other and can clamp and fix the motorcycle frame, which is convenient for fixing the motorcycle frame. By moving the motorcycle frame upward, the pressure on the support plate 401 disappears, and the reaction force of the second spring 4031 causes the support plate 401 to move upward. The support plate 401 moves upward and drives the two groups of clamping plates 402 to move relatively away from each other through the transmission component. The two groups of clamping plates 402 move relatively away from each other and can cancel the fixation of the motorcycle frame, which is convenient for canceling the fixation of the motorcycle frame.

[0053] Specifically in the above embodiment, multiple groups of fixed shafts 403 are vertically arranged at both ends of the bottom plate 40, the support plate 401 is slidably arranged on the multiple groups of fixed shafts 403 in the vertical direction, multiple groups of second springs 4031 are respectively sleeved on the multiple groups of fixed shafts 403, and the two ends of the second springs 4031 are respectively against the bottom plate 40 and the support plate 401.

[0061] See also Figure 1 and Figure 2 In one embodiment, a plurality of sets of universal wheels 103 with self-locking function are arranged at the bottom of the base 10, so as to facilitate the movement and fixation of the device.

[0062] The specific implementation of the above-mentioned motorcycle frame detection device is as follows:

[0063] First, place both ends of the motorcycle frame on the support plate 401. The motorcycle frame drives the support plate 401 downward due to gravity and compresses the second spring 4031 to shrink. The support plate 401 moves downward and drives the rack 408 to move downward. The rack 408 moves downward and meshes with the gear 407 to drive the gear 407 to rotate. The rotation of the gear 407 drives the bidirectional screw 405 to rotate. The rotation of the bidirectional screw 405 and the threaded cooperation with the guide rod 406 drive the two groups of guide rods 406 to drive the two groups of clamping plates 402 to move relatively close. The two groups of clamping plates 402 move relatively close to each other to clamp and fix the motorcycle frame, which is convenient for fixing the motorcycle frame.

[0064] Then, by applying force in the vertical direction and the length direction of the base 10 to the mounting block 307, the mounting block 307 drives the positioning shaft 304 to move and correspond to the positioning hole 3031, and then slide the positioning shaft 304 along the width direction of the base 10 so that the positioning shaft 304 passes through the positioning hole 3031, and the detection head 305 is located on the inner side of the fixed frame 301. At this time, the detection head 305 is coaxial with the positioning hole 3031, so that the detection head 305 corresponds to the hole position of the motorcycle frame, and it is convenient and labor-saving to adjust the position of the detection head 305, and the detection head 305 can be positioned, thereby improving the corresponding accuracy of the detection head 305 and the hole position of the motorcycle frame.

[0065] Finally, by controlling the double-output shaft motor 201 to drive the two groups of first screws 202 to rotate and cooperate with the two groups of first guide blocks 203 threads, the two groups of first guide blocks 203 can be driven to drive the two groups of mounting seats 20 to move relatively close. The two groups of mounting seats 20 can move relatively close to each other and drive multiple groups of detection heads 305 to be correspondingly inserted into the holes on both sides of the motorcycle frame through the fixed frame 301 and the installation frame 302 for detection, which makes the detection convenient and quick.

[0066] By rotating the second screw 309 and engaging the thread of the telescopic shaft 308, the telescopic shaft 308 with the detection head 305 can be driven to move. The movement of the detection head 305 can reduce the distance between the detection head 305 and the corresponding hole position. By rotating the second screw 309 and engaging the thread of the telescopic shaft 308 in the opposite direction, the telescopic shaft 308 with the detection head 305 can be driven to move in the opposite direction. The reverse movement of the detection head 305 can increase the distance between the detection head 305 and the corresponding hole position. It is convenient to adjust the distance between the detection head 305 and the corresponding hole position. By adjusting the distance between the detection head 305 and the corresponding hole position, it is convenient to simultaneously detect the holes that are not in the same vertical plane, thereby improving the practicability of the device.
