[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] like Figure 1-8 As shown, a gear shaft pitch detection device comprises:

[0029] The detection head 2 comprises a housing 21 and an elastic plate 22;

[0030] It also includes a bracket 211 symmetrically arranged on the shell 21, on which a hinge plate 212 is hingedly arranged, and the elastic plate 22 is arranged between the two hinge plates 212. The elastic plate 22 is pushed by the gear shaft and clamped on the surface of the gear shaft in a C-shaped structure.

[0031] Specifically, by starting the motor on the base 1 to rotate, the bidirectional threaded rod set at its output end is driven to rotate, thereby driving the two sliders coupled to the bidirectional threaded rod to move relative to each other, thereby driving the two symmetrically set support seats 3 to move, and then adjusting the distance between the two support seats 3 according to the length of the gear shaft, thereby supporting the gear shaft, thereby improving the adaptability of the device.

[0032] Furthermore, a support column 11 is provided on the top of the base 1, and a top plate 12 is provided on the top of the support column 11. The gear shaft is placed on the support seat 3 for support. The arc-shaped plate on the support seat 3 supports the gear shaft ends of the two gears on the gear shaft respectively, so that the detection head 2 is located between the two gears. The hydraulic rod 121 installed on the top plate 12 is started to further drive the detection head 2 fixed at the output end of the hydraulic rod 121 to move toward the gear shaft, thereby driving the elastic plate 22 to move toward the gear shaft. When the arc top of the elastic plate 22 contacts the gear shaft, as the detection head 2 moves, the elastic plate 22 is pushed by the gear shaft to form a C-shaped structure and clamped on the surface of the gear shaft, such as Figure 7 to Figure 8 As shown, the gear shaft can be quickly clamped and fixed in cooperation with the support seat 3. Since the elastic plate 22 is clamped on the surface of the gear shaft, the elastic plate 22 is coaxial with the gear shaft, thereby achieving leveling of the gear shaft and effectively preventing the gear shaft axis from tilting and affecting the accuracy of the measurement result.

[0033] In the above technology, the detection head 2 is driven to move toward the gear shaft, thereby driving the elastic plate 22 to move toward the gear shaft. When the arc top of the elastic plate 22 contacts the gear shaft, as the detection head 2 moves, the elastic plate 22 is pushed by the gear shaft to form a C-shaped structure and clamped on the surface of the gear shaft, thereby realizing rapid clamping and fixing of the gear shaft. Since the elastic plate 22 is clamped on the surface of the gear shaft, the elastic plate 22 is coaxial with the gear shaft, thereby realizing leveling of the gear shaft. Compared with the prior art, there is no need to repeatedly adjust the clamping mechanism to fix the gear shaft, the structure is simple, and the manufacturing cost is saved. Automatic leveling is achieved in the process of rapid clamping, which saves adjustment time and effectively improves the detection efficiency and the accuracy of the detection results.

[0034] As a further embodiment of the present invention, it also includes a dust shield 24 and an infrared distance measuring sensor 26 which are symmetrically arranged on the housing 21 and the two are arranged correspondingly.

[0035] Specifically, by setting up the dust shield 24, the infrared ranging sensor 26 can be protected when not in use, effectively preventing the lens of the infrared ranging sensor 26 from being exposed to the outside and accumulating dust to affect detection, while avoiding damage to the lens of the infrared ranging sensor 26 caused by external force impact, thereby increasing the service life of the device.

[0036] As a further embodiment of the present invention, the invention further comprises a push rod 28 fixedly arranged at the arc top of the elastic plate 22 , which is connected to the dust shielding plate 24 via a connecting rod 241 .

[0037] Specifically, during the deformation process, the elastic plate 22 moves the push rod 28 through the arc top, thereby driving the dust shield 24 to move through the connecting rod 241, so that the dust shield 24 is away from the infrared ranging sensor 26, so that the lens of the infrared ranging sensor 26 is exposed, and the pitch of the gear shaft is detected. No additional driving source is required to drive the dust shield 24 to move. As the elastic plate 22 completes clamping the gear shaft, the dust shield 24 automatically opens, which effectively simplifies the structure and saves manufacturing costs.

[0038] As a further embodiment provided by the present invention, the present invention further comprises a soot blowing nozzle 23 symmetrically arranged on the housing 21 , which is arranged corresponding to the infrared distance measuring sensor 26 .

[0039] Specifically, the dust attached to the lens surface is blown off by blowing air to the lens of the infrared distance measuring sensor 26 through the dust blowing nozzle 23, so that the infrared distance measuring sensor 26 is not affected by the dust and can perform detection better, thereby further improving the detection accuracy.

[0040] As a further embodiment of the present invention, it also includes a cylinder 29 arranged at the top of the housing 21, in which a piston plate 291 is slidably arranged.

[0041] Specifically, the cylinder 29 is connected to the soot blowing nozzle 23 through the connecting pipe 25. By driving the piston plate 291 to move in the cylinder 29, the gas in the cylinder 29 is squeezed into the connecting pipe 25 and blown toward the lens of the infrared ranging sensor 26 through the soot blowing nozzle 23, without the need for an additional pump gas source to pump gas, further simplifying the structure and saving manufacturing costs.

[0042] As a further embodiment of the present invention, the present invention further comprises a piston rod 27 fixedly disposed on the piston plate 291 , which is sleeved on the push rod 28 .

[0043] Specifically, the hydraulic rod 121 installed on the top plate 12 is started, which further drives the detection head 2 fixed on the output end of the hydraulic rod 121 to move toward the gear shaft, thereby driving the elastic plate 22 to move toward the gear shaft. When the arc top of the elastic plate 22 contacts the gear shaft, as the detection head 2 moves, the elastic plate 22 is pushed by the gear shaft to form a C-shaped structure and clamped on the surface of the gear shaft, such as Figure 7 to Figure 8 As shown, during the deformation process of the elastic plate 22, there are several strokes:

[0044] The arc top of the elastic plate 22 first pushes the push rod 28 to slide in the piston rod 27 and squeezes the first spring 281, thereby driving the dust shield 24 to move through the connecting rod 241, so that the dust shield 24 is away from the infrared ranging sensor 26, so that the lens of the infrared ranging sensor 26 is exposed.

[0045] Furthermore, when the push rod 28 moves to contact the top inner wall of the slide groove set in the piston rod 27, the arc top of the elastic plate 22 continues to push the push rod 28 to move. At the same time, the push rod 28 pushes the piston plate 291 to move in the cylinder 29 and squeezes the second spring 292, thereby squeezing the gas in the cylinder 29 into the connecting pipe 25 and blowing it toward the lens of the infrared ranging sensor 26 through the soot blowing nozzle 23. No additional driving source is required to drive the piston plate 291 to move, thereby further simplifying the structure.

[0046] Furthermore, after the detection is completed, the hydraulic rod 121 is driven to drive the detection head 2 away from the gear shaft, and the first spring 281 and the second spring 292 need to restore their deformation. The first spring 281 pushes the push rod 28 to move in the opposite direction, thereby pushing the elastic plate 22 to the top of the arc to a predetermined curvature, and then the two ends of the elastic plate 22 open and restore the initial state. The second spring 292 also pushes the piston plate 291 to the initial position. Figure 7 shown.

[0047] Working principle: By starting the motor on the base 1 to rotate, the bidirectional threaded rod set at its output end is driven to rotate, thereby driving the two sliders coupled to the bidirectional threaded rod to move relative to each other, thereby driving the two symmetrically arranged support seats 3 to move, thereby adjusting the distance between the two support seats 3 according to the length of the gear shaft, thereby supporting the gear shaft, starting the hydraulic rod 121 installed on the top plate 12, and further driving the detection head 2 fixed at the output end of the hydraulic rod 121 to move toward the gear shaft, thereby driving the elastic plate 22 to move toward the gear shaft. When the arc top of the elastic plate 22 contacts the gear shaft, as the detection head 2 moves, the elastic plate 22 is pushed by the gear shaft to form a C-shaped structure and clamped on the surface of the gear shaft, thereby cooperating with the support seat 3 to achieve rapid clamping and fixing of the gear shaft. During the deformation process of the elastic plate 22, the arc top of the elastic plate 22 first pushes the push rod 28 to slide in the piston rod 27 and squeezes the first spring 281, thereby connecting The rod 241 drives the ash baffle plate 24 to move, thereby making the ash baffle plate 24 away from the infrared ranging sensor 26, so that the lens of the infrared ranging sensor 26 is exposed. When the push rod 28 moves to contact the top inner wall of the slide groove set in the piston rod 27, the arc top of the elastic plate 22 continues to push the push rod 28 to move. At the same time, the push rod 28 pushes the piston plate 291 to move in the cylinder 29 and squeezes the second spring 292, so that the gas in the cylinder 29 is squeezed into the connecting pipe 25 and blown to the lens of the infrared ranging sensor 26 through the ash blowing nozzle 23. After the detection is completed, the hydraulic rod 121 is driven to drive the detection head 2 away from the gear shaft. The first spring 281 and the second spring 292 need to restore the deformation. The first spring 281 pushes the push rod 28 to move in the opposite direction, so as to push the elastic plate 22 arc top to a predetermined curvature. After that, the two ends of the elastic plate 22 open and restore the initial state, and the second spring 292 also pushes the piston plate 291 to the initial position.

[0048] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
