For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0025] like Figures 1-4 As shown, a crankshaft detection equipment capable of detecting surface cracks includes a workbench 1, a rotating component 2 is installed on the left upper end of the workbench 1, a support platform 3 is slidably connected to the right upper end of the workbench 1, and the support platform 3 is slidably connected to the workbench 1 through a slide rail, an X-axis linear module 4 is installed on the rear upper end of the workbench 1, the X-axis linear module 4 is used to drive the ultrasonic detection head 8 to move left and right, an L-shaped frame 9 is installed on the movable end of the X-axis linear module 4, a Y-axis linear module 5 is installed on the upper wall of the L-shaped frame 9, an adjusting component 6 is installed on the movable end of the Y-axis linear module 5, the Y-axis linear module 5 is used to drive the ultrasonic detection head 8 to move forward and backward, and three buffer components 7 are installed on the lower end of the adjusting component 6, and the lower ends of the three buffer components 7 are all installed with ultrasonic detection heads 8.

[0026] In order to improve the detection efficiency, the adjustment component 6 and multiple ultrasonic detection heads 8 work together to detect different positions of the crankshaft, reducing subsequent operation steps and saving time. The specific structure is: the adjustment component 6 includes a concave plate 61, which is installed on the movable end of the Y-axis linear module 5. The left end of the concave plate 61 is installed with a first motor 62, and the middle part of the inner wall of the concave plate 61 is fixedly connected with a fixed block 63. The output end of the first motor 62 is movably inserted into the concave plate 61 and fixedly connected with a positive and negative threaded rod 64. The right end of the positive and negative threaded rod 64 passes through the fixed block 63 and is movably connected to the right inner wall of the concave plate 61. The outer surface of the positive and negative threaded rod 64 is threadedly sleeved with two movable blocks 65 symmetrically distributed on the left and right. The lower ends of the two movable blocks 65 and the fixed block 63 are both installed with electric cylinders 66. The electric cylinder 66 is used to drive the ultrasonic detection head 8 close to the crankshaft.

[0027] When the detection part is uneven, the buffer component 7 can buffer the position detected by the ultrasonic detection head 8 to prevent the ultrasonic detection head 8 from continuously contacting the uneven position and causing damage, thereby extending the service life of the probe and protecting the shaft surface, ensuring that subsequent detection can be carried out continuously. The specific structure is: the buffer component 7 includes a connecting plate 71, which is installed at the lower end of the electric cylinder 66, and a spring 72 is installed at the lower end of the connecting plate 71. A connecting disk 74 is installed at the lower end of the spring 72, and two guide rods 73 are installed at the upper end of the connecting disk 74. The guide rods 73 guide the movement of the connecting disk 74, and the guide rods 73 are movably inserted into the upper side of the connecting plate 71.

[0028] The ultrasonic detection head 8 is mounted on the lower end of the connecting plate 71 , and the ultrasonic detection head 8 is fixed to the connecting plate 71 by bolts.

[0029] The rotating component 2 includes a vertical plate 21, which is installed on the upper left side of the workbench 1. A second motor 22 is installed on the left end of the vertical plate 21. The output end of the second motor 22 is movably inserted into the right end of the vertical plate 21 and fixedly connected to a circular plate 23. A guide plate 24 is installed on the right end of the circular plate 23. The right end of the guide plate 24 is slidably connected to a three-jaw chuck 25. When the shaft neck and the axis of the main shaft end are not on the same horizontal line, rotate the three-jaw chuck 25 and the screw on the support platform 3 to move the three-jaw chuck 25 and the support platform 3 back and forth so that the axis position of the shaft neck and the center position of the circular plate 23 are on the same horizontal line, and the shaft neck in other parts can be inspected.

[0030] The support platform 3 and the three-jaw chuck 25 are both provided with screws, which are used to make the support platform 3 and the three-jaw chuck 25 press against the guide rail.

[0031] The present invention proposes a crankshaft inspection device capable of detecting surface cracks. When in use, the front end of the crankshaft is fixed on the three-jaw chuck 25, and the rear end is placed on the support table. According to the position of the same axis journal, the output end of the first motor 62 is controlled to drive the forward and reverse threaded rods 64 to rotate, and the forward and reverse threaded rods 64 drive the two moving blocks 65 to move closer or farther backward, thereby adjusting the left and right ultrasonic detection heads 8 so that the left and right ultrasonic detection heads 8 are located above the left and right journals, and the middle ultrasonic detection head 8 is located on the middle journal. Then, the output of the three electric cylinders 66 is controlled. The ultrasonic end drives the ultrasonic detection head 8 to move downward and close to the surface of the crank neck, and controls the second motor 22 to drive the crankshaft to rotate through the circular plate 23, so that different positions of the crankshaft can be detected simultaneously. The ultrasonic detection head 8 transmits the electrical signal to the ultrasonic flaw detector, so that the situation of the cracks on the surface of the crankshaft can be understood. When the ultrasonic detection head 8 contacts the uneven position, the ultrasonic detection head 8 moves upward under pressure, and the ultrasonic detection head 8 drives the connecting plate 74 to move upward, compressing the spring 72 to prevent the ultrasonic detection head 8 from continuously contacting the uneven position and causing damage.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
