Description

Technical Field

[0001] The present invention relates to the technical field of gear detection, and specifically to an intelligent detection device for the tooth angle of a helical gear with specification self - adaptation based on a sensor. Background Art

[0002] Gears are important components in mechanical equipment. The quality of their processing has a direct impact on the vibration noise and reliability of the equipment assembly. That is, after the gears are produced, it is necessary to detect the tooth angle of the gears. Existing gear angle detection devices usually detect the tooth angle of spur gears. However, when dealing with helical gears, due to the limitation of the helical teeth of the helical gear, the detection of the tooth angle is inaccurate, and it is necessary to manually position each tooth, and continuous scanning of the entire tooth surface cannot be achieved, resulting in low detection efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide an intelligent detection device for the tooth angle of a helical gear with specification self - adaptation based on a sensor to solve the problems raised in the prior art.

[0004] To achieve the above purpose, the present invention provides the following technical solutions: An intelligent detection device for the tooth angle of a helical gear with specification self - adaptation based on a sensor includes a detection body. A detection cavity is arranged inside the detection body. A cover body is arranged above the detection cavity. The cover body is separated from the detection body. A support frame is arranged on the side of the cover body away from the detection body. A hydraulic cylinder is arranged on the support frame. The push rod of the hydraulic cylinder is connected to the cover body. A waste outlet is arranged at the bottom of the detection cavity.

[0005] Place the helical gear in the detection cavity. Then the controller controls the hydraulic cylinder to start. The push rod of the hydraulic cylinder pushes the cover body to move, so that the cover body moves towards the side close to the helical gear. Finally, the cover body contacts the top of the helical gear and finally reaches a sealed state. Then water flows through the gap between adjacent two teeth, cleaning the impurities and chips generated by milling between the teeth, and discharging them through the waste outlet. Finally, gas is sprayed between the two teeth, and by detecting the change in air pressure, the angle of the teeth is detected.

[0006] Preferably, the detection cavity is composed of a moving cavity and several moving bodies. The several moving bodies are arranged around the axis of the moving cavity. A slider is arranged at the bottom of the moving cavity. A sliding groove is arranged at the bottom of the moving body. The slider is slidably connected to the sliding groove.

[0007] Preferably, a push block is arranged at the top of the moving body. Several electric cylinders are arranged inside the side wall of the detection body. The push rod of the electric cylinder is connected to the push block. The several moving bodies enclose a circular chamber.

[0008] Preferably, a detection bladder is provided on one side of the moving body away from the detection body. The detection bladder is annular, and a number of air cavities are provided inside the detection bladder. The spatial volumes of the air cavities are equal, and two adjacent air cavities are interconnected. A number of pressure sensors are provided on one side of the detection bladder close to the center of the detection cavity, and the pressure sensors correspond to the air cavities one by one.

[0009] Preferably, an air pump is provided inside several of the moving bodies. The air pump is connected to the detection bladder through a pipeline. A valve is provided on one side of the air cavity away from the moving body. The valve connects the space enclosed by the detection bladder and the air cavity, and the valve opens towards the side away from the air cavity.

[0010] Preferably, a number of delivery ports are provided at the bottom of the detection cavity, and the delivery ports are connected to the impurity outlet.

[0011] Preferably, the delivery port is composed of a horn pipe and a delivery pipe. The top diameter of the horn pipe is larger than the bottom diameter of the horn pipe. A retaining groove is provided on the side wall of the horn pipe, and an annular baffle is provided on the retaining groove. The annular baffle is made of a flexible material, and an electromagnetic spring is provided between the annular baffle and the retaining groove.

[0012] Preferably, a water pipe is provided on the top of the cover body, and a number of water channels are provided on the bottom of the cover body. A water storage tank is provided outside the detection body. A water pump is provided inside the water storage tank. The water pump is connected to the water pipe through a pipeline, and the water channels are connected to the water pipe.

[0013] Preferably, the height of the water channel on one side close to the axis of the cover body is greater than the height of the water channel on one side away from the axis of the cover body.

[0014] Preferably, a helical gear is placed at the center of the detection bladder. The space enclosed by two adjacent teeth of the helical gear, the detection bladder, the water channel and the bottom of the detection cavity is a sealed chamber.

[0015] Place the helical gear at the center of the circular ring of the detection bladder. Subsequently, the hydraulic cylinder pushes the cover body to move, so that the cover body moves to the top of the helical gear. At this time, the axes of the cover body, the helical gear and the detection cavity are in a coincident state. Subsequently, the controller controls the movement of the electric cylinder inside the detection body, and the push rod of the electric cylinder immediately pushes the push block to move. The push block drives the moving body to move, and the moving body moves along the chute to the side away from the moving cavity, and then the moving body drives the detection bladder to move; A number of moving bodies move synchronously, causing the detection bladder to contract towards the side closer to the axis of the detection cavity. During the movement of the detection bladder, since the detection bladder is annular, when the inner wall of the detection bladder contacts the outer wall of the helical gear, the controller controls the electric cylinder to close. Then, the detection bladder, the detection cavity, and the cover body cooperate with each other to complete the wrapping of the helical gear. Subsequently, the controller controls the air pump to start. The air pump extracts external air and transports it to the detection bladder through a pipeline. Since the air cavities are in a connected state, a number of air cavities input gas synchronously, and thus the air pressure in each air cavity is in the same state. As the gas is continuously input, the side of the detection bladder close to the helical gear will expand under the action of the air pressure, and then the detection bladder expands into the gap between two adjacent teeth, so that the two adjacent teeth, the detection bladder, the water chute, and the bottom of the detection cavity jointly enclose a sealed chamber; At this time, the controller controls the electromagnetic spring in the horn tube to be energized. After the electromagnetic spring is energized, it contracts, causing the electromagnetic spring to pull the annular baffle to move during contraction, so that the annular baffle contracts into the retaining groove, and then the delivery port connects the sealed space and the debris outlet; Subsequently, the controller controls the water pump in the water storage tank to start. The water pump transports water through a pipeline to the water flow pipe and then to the water chute through the water flow pipe. Since the height of the water chute on the side closer to the axis of the cover body is greater than the height of the water chute on the side farther from the axis of the cover body, the flow rate of the water increases during the flow, and the water flows vertically from the top of the helical gear to the bottom of the helical gear. And because the teeth of the helical gear are helical, the water flows down in a spiral form under the influence of gravity, and the gap between the teeth is impacted during the fall of the water, thus completing the cleaning of the gap between the teeth, preventing impurities and milling debris from remaining in the gap between the teeth and interfering with subsequent angle detection. The water after cleaning flows through the horn tube and the delivery pipe to the debris outlet. Since the diameter of the top of the horn tube is larger than the diameter of the bottom of the horn tube, the flow rate of the water further increases during the output process, thereby improving the cleaning efficiency of the gap between the teeth and shortening the cleaning time; When the cleaning is completed, the controller controls the valve between the water chute and the water flow pipe to close. At this time, the air pump continuously inputs gas into the detection bladder. When the air pressure in the air cavity is greater than the bearing air pressure, the gas in the air cavity pushes the valve flap, and then the gas is transported to the sealed space through the valve flap, and then the gas flows along the side of the teeth, cleaning the remaining water droplets on the side of the teeth during the flow, thus realizing the drying of the teeth; After the enclosed space is dried, control the electromagnetic spring to cut off the power, and then the annular baffle resets under the action of the electromagnetic spring, so that the horn tube is blocked. At this time, gas is continuously input into the enclosed space. As the gas is continuously input, the air pressure in the enclosed space rises. During the process of the air pressure rising, the pressure sensor always detects the air pressure in the enclosed space, converts the pressure signal into an electrical signal, and transmits it to the controller; if the air pressure in the gap between each tooth of the helical gear rises synchronously and the pressure values are in an equal state, then the tooth angles of the helical gear are in the same state; if during the process of the air pressure rising, the air pressure in a tooth gap is greater than or less than the air pressure in another tooth gap, if the air pressure is greater than the air pressure in another tooth gap, then the angle of this tooth gap is greater than the angle of the other tooth gap, and if the air pressure is less than the air pressure in another tooth gap, then the angle of this tooth gap is less than the angle of the other tooth gap. By detecting the change of air pressure, the detection of the tooth angle of the helical gear is completed. Compared with laser detection, the laser will be affected by the side of the tooth, making the laser unable to detect the helical tooth, so that the angle cannot be accurately detected. However, through the change of air pressure, when the tooth gap changes, the difference in air pressure in the tooth gap can be intuitively reflected, so that the angle difference of the helical gear teeth can be detected faster, improving the detection efficiency of the tooth angle and thus improving the quality of helical gear production.

[0016] Compared with the prior art, the beneficial effects of the present invention are: By detecting the change of air pressure, the detection of the tooth angle of the helical gear is completed. Compared with laser detection, the laser will be affected by the side of the tooth, making the laser unable to detect the helical tooth, so that the angle cannot be accurately detected. However, through the change of air pressure, when the tooth gap changes, the difference in air pressure in the tooth gap can be intuitively reflected, so that the angle difference of the helical gear teeth can be detected faster, improving the detection efficiency of the tooth angle and thus improving the quality of helical gear production.

The air pump is communicated with the detection bladder 16 through a pipeline. A valve 162 is provided on the side of the air chamber 161 away from the moving body 15. The valve 162 communicates the space enclosed by the detection bladder 16 with the air chamber 161, and the valve 162 opens towards the side away from the air chamber 161.

[0023] As a specific embodiment of the present invention, several delivery ports 17 are provided at the bottom of the detection chamber 11. The delivery ports 17 are communicated with the impurity outlet 13. The delivery port 17 is composed of a horn tube 18 and a delivery tube 19. The top diameter of the horn tube 18 is larger than the bottom diameter of the horn tube 18. A retaining groove 181 is provided on the side wall of the horn tube 18. An annular baffle 182 is provided on the retaining groove 181. The annular baffle 182 is made of a flexible material. An electromagnetic spring is provided between the annular baffle 182 and the retaining groove 181.

[0024] As a specific embodiment of the present invention, a water flow pipe 20 is provided at the top of the cover body 12. Several water flow grooves 21 are provided at the bottom of the cover body 12. A water storage tank is provided outside the detection body 1. A water pump is provided inside the water storage tank. The water pump is communicated with the water flow pipe 20 through a pipeline, and the water flow groove 21 is communicated with the water flow pipe 20.

[0025] As a specific embodiment of the present invention, the height of the water flow groove 21 on the side close to the axis of the cover body 12 is greater than the height of the water flow groove 21 on the side away from the axis of the cover body 12.

[0026] As a specific embodiment of the present invention, a helical gear is placed at the center of the detection bladder 16. The space enclosed by two adjacent teeth of the helical gear, the detection bladder 16, the water flow groove 21 and the bottom of the detection chamber 11 forms a sealed chamber.

[0027] The working principle of the present invention: Place the helical gear at the center of the circular ring of the detection bladder 16. Subsequently, the hydraulic cylinder pushes the cover body 12 to move, so that the cover body 12 moves to the top of the helical gear. At this time, the axes of the cover body 12, the helical gear and the detection chamber 11 are in a coincident state. Subsequently, the controller controls the movement of the electric cylinder inside the detection body 1. The push rod of the electric cylinder then pushes the push block 152 to move. The push block 152 drives the moving body 15 to move. The moving body 15 moves along the sliding groove 151 towards the side away from the moving chamber 14, and thus the moving body 15 drives the detection bladder 16 to move; A number of moving bodies 15 move synchronously, causing the detection bladder 16 to contract towards the side closer to the axis of the detection cavity 11. During the movement of the detection bladder 16, since the detection bladder 16 is annular, when the inner wall of the detection bladder 16 contacts the outer wall of the helical gear, the controller controls the electric cylinder to close. Then, the detection bladder 16, the detection cavity 11, and the cover body 12 cooperate with each other to complete the wrapping of the helical gear. Subsequently, the controller controls the air pump to start. The air pump extracts external air and transports it through a pipeline to the detection bladder 16. Since the air cavities 161 are in a connected state, a number of air cavities 161 input gas synchronously, and thus the air pressure in each air cavity 161 is in the same state. As the gas is continuously input, the side of the detection bladder 16 close to the helical gear will expand under the action of the air pressure, and then the detection bladder 16 expands into the gap between two adjacent teeth, so that two adjacent teeth, the detection bladder 16, the water trough 21, and the bottom of the detection cavity 11 jointly enclose a sealed chamber; At this time, the controller controls the electromagnetic spring in the horn tube 18 to be energized. After the electromagnetic spring is energized, it contracts, causing the electromagnetic spring to pull the annular baffle 182 to move during the contraction process, so that the annular baffle 182 contracts into the retaining groove 181, and then the delivery port 17 connects the sealed space and the debris outlet 13; Subsequently, the controller controls the water pump in the water storage tank to start. The water pump transports water through a pipeline to the water flow pipe 20 and then through the water flow pipe 20 to the water trough 21. Since the height of the water trough 21 on the side closer to the axis of the cover body 12 is greater than the height of the water trough 21 on the side farther from the axis of the cover body 12, the flow rate of the water increases during the flow process and vertically flows from the top of the helical gear to the bottom of the helical gear. And because the teeth of the helical gear are helical, the water flow falls in a spiral form under the influence of gravity, and the gap between the teeth is impacted during the falling process of the water flow, thereby completing the cleaning of the tooth gap, preventing impurities and milling debris from remaining in the tooth gap and interfering with subsequent angle detection. The water after cleaning flows through the horn tube 18 and the delivery pipe 19 to the debris outlet 13. Since the top diameter of the horn tube 18 is larger than the bottom diameter of the horn tube 18, the flow rate of the water flow further increases during the output process, thereby improving the cleaning efficiency of the tooth gap and shortening the cleaning time; When the cleaning is completed, the controller controls the valve between the water trough 21 and the water flow pipe 20 to close. At this time, the air pump continuously inputs gas into the detection bladder 16. When the air pressure in the air cavity 161 is greater than the bearing air pressure, the gas in the air cavity 161 pushes the valve flap 162, and then the gas is transported through the valve flap 162 to the sealed space, and then the gas flows along the side of the tooth, and the residual water droplets on the side of the tooth are cleaned during the flowing process, thereby realizing the drying of the tooth; After the enclosed space is dried, control the electromagnetic spring to cut off the power, and then the annular baffle 182 resets under the action of the electromagnetic spring, so that the horn tube 18 is blocked. At this time, gas is continuously input into the enclosed space. As the gas is continuously input, the air pressure in the enclosed space rises. During the process of the air pressure rising, the pressure sensor always detects the air pressure in the enclosed space, converts the pressure signal into an electrical signal, and transmits it to the controller; if the air pressure in the gap between each tooth of the helical gear rises synchronously and the pressure values are in an equal state, then the tooth angles of the helical gear are in the same state; if during the process of the air pressure rising, the air pressure in a tooth gap is greater than or less than the air pressure in another tooth gap, if the air pressure is greater than the air pressure in another tooth gap, then the angle of this tooth gap is greater than the angle of the other tooth gap, and if the air pressure is less than the air pressure in another tooth gap, then the angle of this tooth gap is less than the angle of the other tooth gap.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
