DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] When the existing detection device detects the slender shaft, the detection steps are relatively many and the detection time is long, thereby reducing the working efficiency of the existing detection device.

[0021] In view of this, the utility model provides a detection device for a slender shaft, which realizes one-time detection of both ends of the slender shaft through the cooperation between the motor, the first sprocket, the chain, the second sprocket, the vertical column, the sliding column and the connecting block, thereby solving the problem that the existing detection device has many detection steps and long detection time when detecting the slender shaft, thereby reducing the working efficiency of the existing detection device.

[0022] By those skilled in the art, the components in this case are connected in sequence. For the specific connection and operation sequence, reference should be made to the following working principle. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.

[0023] Example 1, by Figure 1-4It can be seen that a slender shaft detection device in this case includes a detection platform 1, a rotating bracket 5 is provided above the detection platform 1, and support heads 6 are provided on both sides of the rotating bracket 5. The staff puts the slender shaft on the support heads 6 on both sides of the rotating bracket 5, and drives the slender shaft to rotate through an external driving device. A detection component 2 is provided above the rotating bracket 5, and the coaxiality of the shaft ends on both sides of the slender shaft is detected by the detection component 2. The outer wall of the detection platform 1 is fixedly connected to the cover body 3, and the interior of the cover body 3 is provided with a moving mechanism 4. The moving mechanism 4 includes: a motor 41 model is selected according to actual needs and can meet the work requirements. The motor 41 is fixedly connected to the inner wall of the cover body 3 through the motor seat, and the first sprocket 42 is fixedly connected to the output shaft of the motor 41. The motor 41 drives the first sprocket 42 to rotate, and the chain 43 is meshed with the outer wall of the first sprocket 42. The first sprocket 42 drives the chain 43 to move, and the second sprocket 44 is meshed. The second sprocket 44 is connected to the outer wall of the chain 43, and the chain 43 drives the second sprocket 44 to rotate, and is rotatably connected to the inner wall of the cover body 3 through the pin shaft. The vertical column 45 is fixedly connected to the outer wall of the chain 43, and the chain 43 drives the vertical column 45 to move, and is fixedly connected to the outer wall of the swivel bracket 5. The two vertical columns 45 drive the swivel bracket 5 to move, thereby driving the slender shaft to move. The sliding column 46 is slidably engaged with the inner wall of the vertical column 45, and the two vertical columns 45 slide in the sliding column 46 to guide the vertical column 45. The connecting block 47 is fixedly connected to the inner wall of the cover body 3 and the outer wall of the sliding column 46. The adjusting component 48 is arranged on the outside of the detection platform 1, wherein the first sprocket 42 is driven by the motor 41 to drive the chain 43 to drive the vertical column 45 to move, thereby moving the swivel bracket 5, and detecting both ends of the slender shaft at one time. The distance between the supporting heads 6 on both sides is adjusted by the adjusting component 48 to detect slender shafts of different lengths.

[0024] The two vertical columns 45 are driven by the two vertical columns 45 to move, and the two vertical columns 45 drive the swivel bracket 5 to move, thereby driving the slender shaft to move.

[0025] The screw threaded rod 482 is screwed to the inner wall of the screw threaded hole 483 and the screw threaded rod 483 is screwed to the inner wall of the screw threaded hole 483. The screw threaded rod 482 is screwed to the inner wall of the screw threaded hole 483 and the screw threaded rod 483 is screwed to the inner wall of the screw threaded hole 483. The screw threaded rod 482 rotates and appears in the screw threaded hole 483. The knob 481 is fixedly connected to the end of the screw threaded rod 482. The knob 481 drives the screw threaded rod 482 to rotate. When the knob 481 is driven, the screw threaded rod 482 rotates out of the inside of the screw threaded hole 483, so that the connecting plate 484 moves in the screw threaded hole 484, thereby adjusting the distance between the supporting heads 6 on both sides and detecting slender shafts of different lengths.

[0026] During the specific implementation process, it is worth noting that when it is necessary to detect slender shafts of different lengths, the staff will turn the knobs 481 on both sides in turn, and the knobs 481 will drive the threaded column 482 to rotate. The threaded column 482 rotates and appears in the threaded hole 483. The staff will move the support heads 6 on both sides, and the support heads 6 will drive the connecting plates 484 to slide in the rotary bracket 5, and move the support heads 6 on both sides to the specified positions. After completion, the staff will turn the knobs 481 on both sides in the opposite direction in turn, so as to rotate the threaded column 482 into the corresponding threaded hole 483, so as to realize the distance between the support heads 6 and detect slender shafts of different lengths.

[0027] Furthermore, the inner walls of the two support heads 6 are provided with placement grooves 61. The staff places the two ends of the slender shaft in the placement grooves 61 inside the support heads 6 on both sides, so that the placement grooves 61 coincide with the bearing installation positions of the slender shaft;

[0028] During the specific implementation process, it is worth noting that the staff places the two ends of the slender shaft in the placement grooves 61 inside the support heads 6 on both sides, so that the placement grooves 61 coincide with the bearing installation positions of the slender shaft;

[0029] Specifically, first, the staff places the two ends of the slender shaft in the placement grooves 61 inside the support heads 6 on both sides, so that the placement grooves 61 coincide with the bearing installation positions of the slender shaft, and drives the slender shaft to rotate through an external driving device, and uses the detection component 2 to detect the full runout tolerance of the measuring surfaces of the two end shafts of the slender shaft. The detection component 2 transmits the inspection value to the external data collector, and then transmits the collected data to the external computer. By calculating the maximum diameter of the full runout tolerance envelope circle, it is determined whether the coaxiality tolerance of the end shaft of the slender shaft is qualified. When one end of the slender shaft is inspected, the motor 41 is connected to the external power supply, and the motor 41 drives the first sprocket 42 to rotate, the first sprocket 42 drives the chain 43 to move, the chain 43 drives the second sprocket 44 to rotate, and the chain 43 drives the vertical column 45 to move, and the two vertical columns 45 slide in the sliding column 46. The two vertical columns 45 drive the rotary bracket 5 to move, thereby driving the slender shaft to move, and move the other slender shaft to the bottom of the detection component 2, and continue to detect the slender shaft. After completion, stop the motor 41. When it is necessary to detect slender shafts of different lengths, the staff turns the knobs 481 on both sides in turn, and the knobs 481 drive the threaded column 482 to rotate. The threaded column 482 rotates and appears in the threaded hole 483. The staff moves the support heads 6 on both sides, and the support heads 6 drive the connecting plates 484 to slide in the rotary bracket 5, and move the support heads 6 on both sides to the specified position. After completion, the staff turns the knobs 481 on both sides in the opposite direction in turn, thereby rotating the threaded column 482 into the corresponding threaded hole 483, thereby realizing the distance between the support heads 6 and detecting slender shafts of different lengths.

[0030] Example 2, by Figure 1-4 It can be seen that the surface of the detection platform 1 is fixedly connected to a support frame 22, and the surface of the support frame 22 is fixedly connected to an electric telescopic rod 21. The model of the electric telescopic rod 21 is selected according to actual needs and can meet the work. The detection component 2 is installed at the output end of the electric telescopic rod 21;

[0031] In the specific implementation process, it is worth noting that the model of the electric telescopic rod 21 is selected according to actual needs and can meet the work requirements. When the electric telescopic rod 21 is started, the electric telescopic rod 21 drives the detection component 2 to descend to the surface of the slender shaft to detect it. When the electric telescopic rod 21 is stopped, when the detection is completed, the electric telescopic rod 21 drives the detection component 2 to rise back to the initial position;

[0032] Of course, the electric telescopic rod 21 can be replaced by a hydraulic cylinder, the specific model of which is not limited, as long as it meets the technical solution described in this embodiment, or other feasible means can be used to drive the detection component 2 to move;

[0033] Furthermore, the outer wall of the detection platform 1 is fixedly connected to a support leg 11, which moves the detection platform 1. There are four support legs 11. The outer wall of the support leg 11 is fixedly connected to a cross column 12, which connects two adjacent support legs 11 together to improve the stability of the detection platform 1.

[0034] During the specific implementation process, it is worth noting that the support legs 11 move the detection platform 1 . There are four support legs 11 . The crossbar 12 connects two adjacent support legs 11 together to improve the stability of the detection platform 1 .

[0035] Specifically, the electric telescopic rod 21 is started, and the electric telescopic rod 21 drives the detection component 2 to descend to the surface of the slender shaft to detect it. The electric telescopic rod 21 is stopped. When the detection is completed, the electric telescopic rod 21 drives the detection component 2 to rise back to the initial position, and the support legs 11 move the detection platform 1. There are four support legs 11, and the horizontal column 12 connects two adjacent support legs 11 together to improve the stability of the detection platform 1.
