Through the foregoing solution, the problem that the existing ultrasonic detection table cannot be limited after starting the pulley to drive the whole device to move to the designated position, resulting in the device being prone to displacement during ultrasonic detection of the workpiece to be detected and affecting the detection effect is solved.

[0022] For this specific implementation, the support frame 102 is fixedly connected to the mounting plate 101 and is located at the bottom of the mounting plate 101. The roller 103 is rotatably connected to the support frame 102 and is located at the bottom of the support frame 102. By starting the roller 103, through the rotation of the roller 103, the device is driven to move to the position of the fan blade, thereby facilitating the detection of the fan blade.

[0023] Among them, the frame 105 is fixedly connected to the support frame 102 and is located at the bottom of the support frame 102. The pedal 106 is slidably connected to the frame 105 and is located on the side of the frame 105. The electric push rod 107 is fixedly connected to the support frame 102, and the output end of the electric push rod 107 is fixedly connected to the pedal 106 and is located on one side of the support frame 102. The mounting frame 108 is fixedly connected to the pedal 106 and is located on one side of the pedal 106. The friction block 109 is threadedly connected to the mounting frame 108 and is located on the side of the mounting frame 108. The detection mechanism 110 is arranged on one side of the mounting plate 101. First, the staff starts the roller 103 at the bottom of the support frame 102. The roller 103 rotates, driving the support frame 102 to move, and then moving the detection device to the position of the fan blade. At this time, the electric push rod 107 at the bottom of the support frame 102 is started. The output end of the electric push rod 107 pushes the pedal 106 to move on the frame 105, and then the mounting frame 108 moves accordingly, which can drive the friction block 109 to move, so that the friction block 109 can resist the roller 103, and the roller 103 stops rotating. The whole detection device also stops at the designated position accordingly, which is convenient for the staff to place the fan blade to be detected on the detection mechanism 110, and the detection mechanism 110 detects the fan blade, thus solving the problem that the existing ultrasonic detection table cannot be limited in position after starting the pulley to drive the whole device to move to the designated position, resulting in the device being prone to displacement during the ultrasonic detection of the workpiece to be detected, affecting the detection effect.

[0024] Secondly, the detection table 111 is fixedly connected to the mounting plate 101 and is located at the top of the mounting plate 101. The clamping member 112 is slidably connected to the detection table 111 and is located at the top of the detection table 111. The first screw rod 113 is rotatably connected to the detection table 111, threadedly connected to the clamping member 112, and passes through the detection table 111. The turntable 114 is fixedly connected to the first screw rod 113 and is located on one side of the first screw rod 113. Place the fan blade to be detected between the clamping members 112 on the detection table 111. According to the size of the blade, the staff rotates the turntable 114, driving the first screw rod 113 to rotate, so that the two clamping frames can move towards each other and clamp the blade.

[0025] Again, the stabilizing block 115 is fixedly connected to the clamping member 112 and is located on one side of the clamping member 112. The fixing rod 116 is fixedly connected to the inspection table 111, is slidably connected to the stabilizing block 115, and is located on one side of the inspection table 111. When the first screw 113 rotates to drive the clamping member 112 to move, the stabilizing block 115 at the end of the clamping member 112 away from the first screw 113 can move on the fixing rod 116, making the clamping member 112 more stable during movement.

[0026] In addition, the first motor 117 is fixedly connected to the mounting plate 101 and is located on one side of the mounting plate 101. The second screw 118 is fixedly connected to the output end of the first motor 117, is rotatably connected to the mounting plate 101, and is located on one side of the first motor 117. The slider 119 is threadedly connected to the second screw 118 and is located on one side of the second screw 118. After the fan blade is fixed on the clamping member 112, the first motor 117 is started. The output end of the first motor 117 drives the second screw 118 to rotate, so that the slider 119 can axially move on the second screw 118, driving the inspection mechanism 110 to move horizontally.

[0027] Meanwhile, the sliding rod 120 is fixedly connected to the mounting plate 101 and is located on one side of the mounting plate 101. The fixing block 121 is slidably connected to the sliding rod 120 and is located on the side of the sliding rod 120. The second motor 122 is fixedly connected to the fixing block 121 and is located on one side of the fixing block 121.

The connecting rod 124 is fixedly connected to the fixing block 121, is fixedly connected to the slider 119, and is between the fixing block 121 and the slider 119. The mounting bracket 125 is threadedly connected to the third screw rod 123, is slidably connected to the connecting rod 124, and is located on one side of the third screw rod 123. The ultrasonic probe 126 is fixedly connected to the mounting bracket 125 and is located at the bottom of the mounting bracket 125. When the slider 119 axially moves on the second screw rod 118, the connecting rod 124 moves accordingly, which can drive the fixing block 121 to move on the sliding rod 120. At this time, the second motor 122 is started, and the output end of the second motor 122 drives the third screw rod 123 to rotate, so that the mounting bracket 125 can axially move on the third screw rod 123. At the same time, the connecting rod 124 provided on the side of the mounting bracket 125 can keep it stable on the third screw rod 123, and then the ultrasonic probe 126 can be moved to a position close to the fan blade. At this time, the ultrasonic probe 126 is started to detect the arc position of the fan blade tip. The ultrasonic probe 126 detects some physical properties such as the size, nature, position, and material of the blade tip arc.

[0028] The utility model provides a fan blade tip arc detection device. When producing fans, in order to ensure that the fans can be used normally, it is necessary to detect the fan blades, especially the detection of the blade tip arc. During the detection, the staff first starts the roller 103 at the bottom of the support frame 102, and the roller 103 rotates to drive the support frame 102 to move, and then move the detection device to the position of the fan blade. At this time, the electric push rod 107 at the bottom of the support frame 102 is started, and the output end of the electric push rod 107 pushes the pedal 106 to move on the frame 105, so that the installation frame 108 moves accordingly, which can The friction block 109 can be driven to move so that the friction block 109 can resist the roller 103, the roller 103 stops rotating, and the detection device as a whole also stops at the specified position. At this time, the fan blade to be detected is placed between the clamping members 112 on the detection platform 111, and according to the size of the blade, the staff rotates the turntable 114 to drive the first screw 113 to rotate, so that the two clamping frames can move toward each other and clamp the blade. At the same time, the stabilizing block 115 on the end of the clamping member 112 away from the first screw 113 can move on the fixing rod 116, so that the clamping The first motor 117 is started, and the output end of the first motor 117 drives the second screw 118 to rotate, so that the slider 119 can move axially on the second screw 118, driving the detection mechanism 110 to move laterally, and the connecting rod 124 moves accordingly, which can drive the fixing block 121 to move on the sliding rod 120. At this time, the second motor 122 is started, and the output end of the second motor 122 drives the third screw 123 to rotate, so that the mounting bracket 125 can move axially on the third screw 123. At the same time, by setting the The connecting rod 124 on the side of the mounting frame 125 can keep it stable on the third screw 123, so that the ultrasonic probe 126 can be moved to a position close to the fan blade.
