Technical Field

[0002] The mining altimeter is a mining hydraulic support lifting displacement monitoring instrument. It uses the change of oil pressure at vertical height to detect the medium conduction through the probe, and converts it into data for transmission. At present, the sensing probe end in the mining altimeter is sealed in the sensor housing. Therefore, as an important equipment for mine safety monitoring, the processing technology and processing quality of the housing of the mining altimeter will directly affect the durability and reliability of the altimeter.

[0003] At present, the processing of mining altimeter shells mostly adopts traditional mechanical processing methods, such as mechanical cutting, manual welding and basic waterproof testing to complete the processing of the sensor shell. However, this method has problems such as low processing accuracy, low production efficiency and poor product corrosion resistance, and cannot meet the requirements of high precision, high efficiency and high durability of the product. Summary of the invention

[0004] In order to achieve high-efficiency and high-quality production of mining altimeters, the present application provides a sensor housing processing device and process thereof.

[0005] The sensor housing processing device provided in the present application adopts the following technical solution: A processing device for a sensor housing, comprising a detection box, a detection component and a mounting component, wherein the mounting component is arranged in the detection box, the detection box is filled with liquid, the mounting component comprises a support plate, a rotating disk, a rotating shaft and a spinning cylinder, the support plates are vertically arranged in the detection box, one end of the rotating shaft is connected to the rotating disk, and the other end is rotatably connected to the support plate, the detection component comprises a gas storage bottle and a gas delivery pipe, a plurality of gas delivery ports are opened on one side of the rotating disk along the circumferential direction, and a plurality of gas delivery holes are opened inside the rotating disk Grooves, a plurality of the gas delivery hole grooves correspond to a plurality of gas delivery ports one by one and are connected and arranged, a plurality of the spinning cylinders are arranged on the rotating disk, the spinning cylinders are arranged corresponding to the gas delivery ports one by one, a spinning rod parallel to the rotating disk is transmission-connected to the spinning cylinder, one end of the gas delivery hole groove away from the gas delivery port extends to the edge of the rotating disk, one end of the gas delivery pipe is connected to the gas storage bottle, and the other end extends to the edge of the rotating disk and abuts against it, and when the rotating disk is rotated to a specific angle, the end of the gas delivery pipe is connected and arranged to communicate with the gas delivery hole groove.

[0006] By adopting the above technical solution, when the air tightness of the altimeter housing is tested, several housings are installed on the rotating disk through the spinning cylinder, and the inner cavity of the housing is connected to the gas supply port. When the housing rotates with the rotating disk to be immersed in the liquid, the gas supply pipe is connected to the corresponding gas supply hole groove, and gas is injected into the gas supply hole groove of the gas storage bottle box. When the housing leaks, bubbles appear in the liquid, thereby realizing the air tightness test of the housing. Through the mutual cooperation of the detection box, the detection component and the installation component, the effect of high-efficiency and high-quality production of the mining altimeter is achieved.

[0007] Optionally, a first driving member for driving the rotating disk to rotate is provided on the support plate, and the first driving member includes a rotating motor, an incomplete driving gear and a driven gear. The driving motor is provided on the support plate, the incomplete driving gear is transmission-connected to the driving motor, and the driven gear is connected to the rotating shaft. When the incomplete driving gear rotates to a certain angle, the incomplete driving gear is meshed and connected with the driven gear.

[0008] By adopting the above technical solution, when it is necessary to drive the rotating disk to rotate, the driving motor is started, and the incomplete driving gear rotates under the drive of the driving motor. When the incomplete driving gear is engaged with the driven gear, the rotating disk rotates a certain angle under its drive, so that the corresponding shell can be immersed in the liquid for air tightness detection.

[0010] By adopting the above technical solution, the setting of the limit hook, ratchet and tension spring realizes the unidirectional rotation limit of the rotating disk.

[0011] Optionally, carbon dioxide gas is stored in the gas storage cylinder, lime water is filled in the detection box, an electric valve is provided on the gas transmission pipe, and a turbidity sensor is provided in the detection box.

The turbidity sensor detects the clarity of the lime water, realizing accurate detection of the air tightness of the shell.

[0013] Optionally, a drying component is provided on the detection box, and the drying component includes a drying box, a water absorption roller and a drying fan. The drying box is connected to the detection box at a position near the top, and a conveying rail is connected to the inner top wall of the detection box.

A conveying robot arm is slidably connected to the conveying rail, and the water absorption roller is vertically rotatably arranged in the drying box. A plurality of water absorption rollers are provided at both ends of the conveying rail. The drying fan is arranged on the drying box, and the air outlet end of the drying fan is connected to the drying box.

[0014] By adopting the above technical solution, the shell that has passed the airtightness test enters the drying box under the drive of the conveying mechanical arm. The water absorption roller absorbs the moisture on the surface of the shell, and the drying fan dries the remaining moisture, thereby achieving the drying treatment of the altimeter shell and reducing the possibility that the residual moisture on the surface of the shell affects the subsequent operation.

[0015] Optionally, a feeding assembly is provided on the detection box, and the feeding assembly includes a feeding box, a feeding plate, a supporting bottom block and a feeding pipe. A discharge port is provided at the bottom end of the feeding box, and the feeding box is arranged above the supporting bottom block. The feeding plate is slidably arranged between the feeding box and the supporting bottom block and is arranged in close contact with the two. A conveying port corresponding to the discharge port is opened on the feeding plate, and one end of the feeding pipe is arranged in close contact with the bottom of the feeding plate. The inlet end of the feeding pipe and the discharge port are staggered in the vertical direction, and the other end of the feeding pipe extends into the detection box and extends to a side of the rotating disk where the spinning cylinder is arranged.

[0016] By adopting the above technical solution, a number of altimeter shells are stacked in the loading box. When loading, the loading plate slides to the position of the conveying port corresponding to the discharge port, and a altimeter shell falls into the conveying port. The loading plate is moved, and the loading plate drives the altimeter shell to move to the end of the loading tube, and the shell enters the detection box along the loading tube. The altimeter shells are loaded one by one through the setting of the loading assembly.

[0017] Optionally, a one-way blocking spring is provided at one end of the gas delivery hole groove extending to the edge of the rotating disk, a plurality of sealing gaskets are connected to the side of the rotating disk on which the gas delivery port is opened, the plurality of sealing gaskets are arranged in a one-to-one correspondence with the plurality of gas delivery ports, a connecting hole connected to the gas delivery port is opened on the sealing gasket, and a pressure detection module is connected to the side of the sealing gasket facing away from the rotating disk.

[0018] By adopting the above technical solution, the setting of the sealing gasket reduces the possibility of gas in the shell escaping through the gap between the rotating disk and the shell. The pressure detection block detects the air pressure inside the shell and determines whether the pressure reduction value exceeds the specified threshold, thereby realizing accurate detection of air tightness.

[0019] A processing technology for a sensor housing comprises the following steps: S1: Laser cutting: Use a laser cutting machine to perform high-precision cutting of the raw materials of the mining altimeter housing; S2: Argon arc welding: The cut altimeter housing is welded by argon arc welding to complete the welding process between the housing structures; S3: Leakage test: Perform a leak test on the altimeter housing to detect the sealing performance of the housing; S4: Shell drying: Dry the altimeter shell after the leak test; S5: Salt spray test: Through the simulated salt spray test, the reliability and corrosion resistance of the altimeter housing in harsh environments are tested.

[0020] By adopting the above technical solutions, laser cutting can achieve precise cutting of raw materials. Through argon arc welding, the possibility of rusting at the welding position of the shell during use is reduced. The shell is tested for leakproofness to ensure the tightness of the shell during use. The shell that has passed the leakproof test is dried to reduce the possibility that its surface moisture will affect the accuracy of the salt spray test. The corrosion resistance and reliability of the shell are tested through the salt spray test.

[0021] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the cooperation of the detection box, detection components and installation components, it has the effect of achieving high efficiency and high quality production of mining altimeters; 2.

[0038] Reference Figure 1 A processing technology for a sensor housing includes the following technical means: first, a laser cutting process is used to perform high-precision cutting of the raw material of the mining altimeter housing. Since the high-power laser density can quickly heat the material to the vaporization temperature, as the light beam moves, the holes generated by the laser continuously form a very narrow slit, completing the cutting of the material. The use of laser cutting can ensure the flatness and dimensional accuracy of the cutting surface, which helps to improve the processing quality of the housing. Then, the welding process of each component of the housing is completed by argon arc welding. Argon arc welding uses argon gas to protect the metal welding material, so that the welding material cannot come into contact with oxygen in the air, thereby preventing the oxidation of the welding material. It helps to increase the possibility of rusting of the welding parts of the housing during use, and further improves the production quality of the housing.

[0039] Reference Figure 1 After the welding of the shell is completed, the altimeter shell is tested for air tightness to ensure its sealing performance during use and to ensure the service life of the altimeter. After passing the air tightness test, the altimeter shell is subjected to a salt spray test using a salt spray tester to test the corrosion resistance and reliability of the altimeter shell in harsh environments. In this application, copper salt is used to accelerate the acetate spray test to speed up the salt spray test and improve the efficiency of product testing.

[0040] Reference Figure 2 and Figure 4When the altimeter housing is tested for air tightness, several altimeter housings (the altimeter housings in the attached drawings are only a schematic representation, and in actual use, the altimeter housings may have other forms) are stacked in the same direction in the loading box 51. When the loading test is required, the loading plate 52 is driven by the loading cylinder 56 to move to the position corresponding to the conveying port 19 and the discharge port 18. The altimeter housing located at the bottom falls into the conveying port 19 for conveying, and the loading plate 52 drives the housing located therein to move to the position corresponding to the end of the loading pipe 54. The housing in the conveying port 19 falls into the loading pipe 54 and slides into the detection box 1 along the loading pipe 54. At this time, the output shaft of the rotating cylinder 57 extends and drives the rotating extension plate 55 to rotate to a horizontal state. The setting of the limit retaining edge 58 prevents the housing from falling directly into the bottom of the detection box 1. The housing moves to the rotating extension plate 55, and at this time, the open end of the housing corresponds to one of the sealing pads 9 on the rotating disk 22. The spinning cylinder 24 is started and the shell and the sealing gasket 9 are pressed tightly by the spinning rod 25 and the pressing block 26. The provision of the sealing gasket 9 reduces the possibility of gas overflowing from the joint between the rotating disk 22 and the shell.

[0041] Reference Figure 4 and Figure 5 After the loading and installation of the housing is completed, the output shaft of the rotating cylinder 57 is shortened, and the rotating extension plate 55 is reset to avoid interference with the rotation of the rotating disk 22. The rotating motor 10 is started and drives the incomplete driving gear 11 to rotate. When the incomplete driving gear 11 rotates to engage with the driven gear 12, the rotating disk 22 rotates. The setting of the incomplete gear realizes the intermittent drive of the rotating disk 22. When the rotating disk 22 rotates, the limit hook 16 bounces on the ratchet 13, realizing the unidirectional rotation limit of the rotating disk 22, reducing the continuous rotation of the rotating disk 22 under the action of inertia when it needs to stop.

[0042] Reference Figure 2 and Figure 3, one of the shells connected to the rotating disk 22 moves with the rotating disk 22 to a position close to the bottom of the detection box 1. At this time, the shell is immersed in clear lime water, and one end of the gas delivery hole slot 7 corresponding to the workstation is connected to the open end of the gas delivery pipe 33. The electric valve 34 is opened to inject carbon dioxide gas into the gas delivery pipe 33 and the gas delivery hole slot 7. The pressure detection module 31 detects the air pressure inside the shell in real time to determine whether the drop value of the air pressure within a certain period of time exceeds the threshold. At the same time, when the air tightness of the shell is not good, the carbon dioxide gas in the shell leaks into the clear lime water, causing it to become turbid. At this time, the turbidity sensor 35 set in the detection box 1 detects that the liquid becomes turbid and sends an electrical signal to the control system (not shown in the figure). The liquid level sensor 36 detects the liquid content in the detection box 1 to avoid the possibility of too little or too much liquid. The setting of the one-way blocking spring 8 avoids the possibility of lime water flowing into the gas delivery hole slot 7 during the rotation process.

[0043] Reference Figure 4 and Figure 6 After the air tightness test of the shell is completed, the shell rotates with the rotating disk 22 to the position corresponding to the conveying rail 20, and the spin cylinder 24 releases the limit on the shell. The conveying mechanical arm 27 transports the tested shell. The shell enters the drying box 41 driven by the conveying mechanical arm 27. The rotating motor 10 is started, and the plurality of transmission wheels 43 rotate synchronously driven by the transmission chain 44, and the water absorption roller 42 wipes the shell passing therethrough. The drying fan 46 is started to dry the residual moisture on the shell, reducing the influence of the residual moisture on the subsequent salt spray test.

[0044] The implementation principle of a sensor housing processing device in the embodiment of the present application is as follows: first, laser cutting is used to cut the mining raw material. Then, the welding of the various parts of the housing is completed by argon arc welding. After the welding of the housing is completed, the altimeter housing is tested for air tightness. After passing the air tightness test, a salt spray test machine is used to perform a salt spray test on the altimeter housing.

[0045] When the air tightness test is performed on the altimeter housing, the housing is loaded one by one through the loading assembly 5, and the spinning cylinder 24 fixes the housing on the rotating disk 22. One of the housings connected to the rotating disk 22 moves with the rotating disk 22 to a position close to the bottom of the detection box 1. At this time, the housing is immersed in clear lime water, and one end of the gas delivery hole groove 7 corresponding to the workstation is connected to the open end of the gas delivery pipe 33. Carbon dioxide gas is injected into the gas delivery pipe 33 and the gas delivery hole groove 7. When the air tightness of the housing is not good, the carbon dioxide gas in the housing leaks into the clear lime water, causing it to become turbid. At this time, the turbidity sensor 35 arranged in the detection box 1 detects that the liquid becomes turbid and sends an electrical signal to the control system. After completing the air tightness test of the housing, the housing enters the drying box 41 for drying, which reduces the influence of residual moisture on the subsequent salt spray test.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
