Description

Technical Field

[0001] This invention relates to the field of hose crimping machine technology, specifically a self-testing hose crimping machine for joint sealing. Background Technology

[0002] Hose crimping machines, also known as hose locking machines or hose clamping machines, are widely used in engineering machinery, mining, agricultural equipment and automobile repair. They are an indispensable key piece of equipment for the mass production and on-site maintenance of hose assemblies. They are professional equipment used to permanently crimp hydraulic hoses, metal hoses and fittings. Their working principle is to drive the mold to shrink radially through the hydraulic system, which firmly "bites" the fitting sleeve onto the hose, forming a high-pressure resistant and pull-out resistant sealed connection.

[0003] Under current technology, when using a pipe crimping machine, workers need to place the pipes themselves, then start the pressing process, and after pressing, open the mold to remove the pipes. Then, the pipes are sent in batches to the testing equipment for inspection. This process is labor-intensive and inefficient. If the pressure of the pipe crimping machine is insufficient or the mold is severely worn, the delay in testing will result in a large number of defective products, which will seriously affect production quality and efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a self-inspection type pipe clamping machine for joint sealing, so as to solve the problems of large workload, low efficiency and large number of defective products caused by the delay in inspection after pipe clamping in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The self-testing coupling sealing type coupling machine includes an operating table, on which a coupling cylinder and a controller are installed. The coupling cylinder is divided into an inlet end and an outlet end. A coupling telescopic rod is installed on the side of the coupling cylinder near the outlet end. A coupling shaft is installed at the end of the coupling telescopic rod. A coupling block is provided inside the coupling cylinder. The coupling shaft mates with the conical surface of the coupling block. A flap mold is provided on the coupling block.

[0006] A base is installed on the side of the operating table near the outlet end, and a detection element is provided on the base. A material transfer element is provided on the side of the base away from the operating table. The detection element includes a sealing element and a quick-change element. The quick-change element and the sealing element are provided on the base.

[0007] The sealing element includes a front sealing ring, a rear sealing ring, a sealing cavity, and a constant pressure valve. The base is provided with a front sealing ring and a rear sealing ring, which cooperate to form a sealing cavity. The sealing cavity is provided with a constant pressure valve. The sealing performance is detected by detecting the amount of gas passing through the constant pressure valve. The material transfer element distributes the product according to the detection result.

[0008] When hoses need to be crimped, the hose is placed into the crimping cylinder, and the crimping machine is started via the operating table. The crimping telescopic rod pushes the crimping shaft towards the inlet end. The crimping shaft, through the conical surface, pushes the crimping block, causing the valve mold to retract inward to complete the crimping. After the joint is crimped, the transfer device moves the hose to the testing point. When it reaches the testing point, the front sealing ring, the rear sealing ring, and the hose cooperate to form a sealing cavity. Gas is introduced into the sealing cavity through a constant pressure valve. If the seal is poor, a large amount of gas will always pass through the constant pressure valve; if the seal is good, no gas or only a small amount of gas will pass through the constant pressure valve. This method is used to test the seal. The hose is directly tested for seal after crimping. On the one hand, this saves the time of transferring the crimped hose to the seal test point, improving production efficiency. On the other hand, if the batch of products has poor seal, the workers can repair the crimping machine in time, avoiding a large number of defective products and improving production quality.

[0009] As a preferred technical solution, the sealing element includes a detection channel, a detection ring, a sealing telescopic rod, an arc plate, an air inlet pipe, a flow meter, a front sealing groove, and a rear sealing groove;

[0010] The base is provided with a detection channel, and a detection ring is installed in the detection channel. Multiple sealing telescopic rods are installed in the detection ring.

A constant pressure valve and a flow meter are installed on the air inlet pipe. Each of the multiple arc plates has a front sealing groove and a rear sealing groove. The multiple front sealing grooves are connected by a front sealing ring, and the multiple rear sealing grooves are connected by a rear sealing ring. The front sealing ring, the rear sealing ring and the product form a sealed cavity.

[0011] As a preferred technical solution, the quick-change component includes a changing seat, meshing teeth, a drive gear, and a drive motor;

A drive motor is mounted on the base, and the drive shaft of the drive motor is connected to the drive gear. The rotating seat has multiple detection channels, and each detection channel is provided with a seal. The seals in each detection channel are of different specifications.

[0013] As a preferred technical solution, the rotating seat is provided with a main air passage, the main air passage is provided with multiple mounting holes, the air inlet pipe extends into the mounting holes, an air supply pipe is installed on the main air passage, the air supply pipe is rotatably connected to the main air passage, and an air pump is connected to the air supply pipe.

[0014] As a preferred technical solution, the material transfer component includes a discharge rod, a mounting base, a top rod, and a support plate;

[0015] A discharge rod is provided on the side of the base away from the operating table. A mounting base is installed at the end of the discharge rod. Multiple push rods are installed on the mounting base. The multiple push rods are arranged in a circle on the mounting base. A support plate is installed at the end of the push rod.

[0016] As a preferred technical solution, a displacement sensor is installed on the mounting base, and the displacement sensor is used to detect the position of the mounting base.

[0017] As a preferred technical solution, the clamping shaft is provided with multiple fitting grooves, the fitting grooves are conical, multiple elastic elements are installed inside the clamping tube, and clamping blocks are installed at the ends of the elastic elements. The clamping blocks are conical on the side facing the fitting groove, and cooperate with the conical surface of the fitting groove to form a clamping conical surface.

[0018] As a preferred technical solution, the flow meter is electrically connected to the controller, and the controller classifies the sealing performance into three levels: qualified, rework, and scrap based on the feedback from the flow meter.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This application performs a sealing test at the outlet of the hose crimping machine. On the one hand, it saves the time of transferring the crimped hose to the sealing test point, thus improving production efficiency. On the other hand, if the sealing performance of a batch of products is poor, workers can repair the hose crimping machine in a timely manner, avoiding the production of a large number of defective products and improving production quality.

[0021] 2. The precision testing of this flow meter can accurately determine the sealing performance, resulting in more accurate test results and further ensuring the quality of the hose clamping.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example: Figures 1-10As shown, the present invention provides a technical solution for a self-testing coupling machine for joint sealing. The self-testing coupling machine for joint sealing includes an operating table 1, on which a coupling cylinder 2 and a controller 3 are installed. The coupling cylinder 2 is divided into an inlet end 4 and an outlet end 5. A coupling telescopic rod 6 is installed on the side of the coupling cylinder 2 near the outlet end 5. A coupling shaft 7 is installed at the end of the coupling telescopic rod 6. A coupling block 8 is provided inside the coupling cylinder 2. The coupling shaft 7 and the coupling block 8 are in conical contact. A flap mold 10 is provided on the coupling block 8.

[0037] A base 11 is installed on the side of the operating table 1 near the outlet end 5. A detection element is provided on the base 11. A material transfer element is provided on the side of the base 11 away from the operating table 1. The detection element includes a sealing element and a quick-change element. The quick-change element and the sealing element are provided on the base 11.

[0038] The sealing components include a front sealing ring 12, a rear sealing ring 13, a sealing cavity 14, and a constant pressure valve 15. The front sealing ring 12 and the rear sealing ring 13 are provided on the base 11. The front sealing ring 12 and the rear sealing ring 13 cooperate to form the sealing cavity 14. The constant pressure valve 15 is provided on the sealing cavity 14. The sealing performance is achieved by detecting the amount of gas passing through the constant pressure valve 15. The material transfer component divides the product according to the detection result.

[0039] When hoses need to be crimped, the hose is placed into the crimping cylinder 2. The crimping machine is started via the operating table 1. The crimping telescopic rod 6 pushes the crimping shaft 7 towards the inlet end 4. The crimping shaft 7, through the conical surface, pushes the crimping block 8, causing the valve mold 10 to retract inward to complete the crimping. After the joint is crimped, the material transfer component moves the hose to the testing point. When it is moved to the testing point, the front sealing ring 12, the rear sealing ring 13, and the hose cooperate to form a sealing cavity 14. Gas is introduced into the sealing cavity 14 through the constant pressure valve 15. If the sealing is poor, a large amount of gas will always pass through the constant pressure valve 15. If the sealing is good, there will be no gas or only a small amount of gas passing through the constant pressure valve 15. This method is used to test the sealing performance. The sealing performance of the hose is tested directly after crimping. On the one hand, it saves the time of transferring the crimped hose to the sealing performance test point, improving production efficiency. On the other hand, if the sealing performance of a batch of products is poor, the workers can repair the crimping machine in time, avoiding a large number of defective products and improving production quality.

[0040] The sealing components include a detection channel 16, a detection ring 17, a sealing telescopic rod 18, an arc plate 19, an air inlet pipe 20, a flow meter 21, a front sealing groove 22, and a rear sealing groove 23;

[0041] A detection channel 16 is provided on the base 11. A detection ring 17 is installed in the detection channel 16. Multiple sealing telescopic rods 18 are installed in the detection ring 17. The multiple sealing telescopic rods 18 are arranged in a circle. An arc plate 19 is installed at the end of each of the multiple sealing telescopic rods 18. An air inlet pipe 20 is installed on one of the arc plates 19. A constant pressure valve 15 and a flow meter 21 are installed on the air inlet pipe 20. A front sealing groove 22 and a rear sealing groove 23 are opened on each of the multiple arc plates 19. The multiple front sealing grooves 22 are connected by a front sealing ring 12. The multiple rear sealing grooves 23 are connected by a rear sealing ring 13. The front sealing ring 12 and the rear sealing ring 13 form a sealing cavity 14 with the product.

[0042] During testing, controller 3 controls the extension of the sealing telescopic rod 18, which pushes the arc plate 19 to make the front sealing ring 12 tightly adhere to the hose and the rear sealing ring 13 tightly adhere to the outer sleeve, forming a sealing cavity 14 between the front sealing ring 12, the rear sealing ring 13, the hose, and the outer sleeve. After controller 3 controls the extension of the sealing telescopic rod 18, controller 3 controls the input of gas into the sealing cavity 14. Due to the constant pressure valve 15, the gas pressure in the sealing cavity 14 should be the same as the set pressure of the constant pressure valve 15. When the seal is good, the flow meter 21 detects that there is no or only a small amount of gas passing through the flow meter 21. When the seal is poor, due to gas leakage, the gas pressure in the sealing cavity 14 can never reach the specified gas pressure, and the flow meter 21 detects that a large amount of gas continuously passes through the constant pressure valve 15. Through this precise detection by the flow meter 21, the seal can be accurately judged, the test results are more accurate, and the quality of the hose clamping is further guaranteed.

[0043] The quick-change component includes a changing seat 24, meshing teeth 25, drive gear 26, and drive motor 27;

[0044] A rotating seat 24 is rotatably mounted on the base 11. The outer wall of the rotating seat 24 is provided with meshing teeth 25. A drive gear 26 is mounted on the base 11 and meshes with the meshing teeth 25. A drive motor 27 is mounted on the base 11 and the drive shaft of the drive motor 27 is connected to the drive gear 26. Multiple detection channels 16 are opened on the rotating seat 24. Each detection channel 16 is provided with a seal, and the seal in each detection channel 16 is of a different specification.

[0045] The front sealing ring 12 and rear sealing ring 13 of the seals in different detection channels 16 have different specifications. When it is necessary to perform tube clamping and testing on hoses of different sizes, the controller 3 is used for adjustment. The controller 3 will start the drive motor 27 to drive the drive gear 26 to rotate. The drive gear 26, due to its meshing with the meshing gear 25, drives the rotating seat 24 to rotate, so that the corresponding detection channel 16 is aligned with the tube clamping cylinder 2, ensuring the sealing performance of the sealing cavity 14, ensuring the accuracy of the test results, and avoiding the complicated steps of changing the test pieces for hoses of different sizes, shortening the testing time and improving efficiency.

[0046] The rotating seat 24 has a main air passage 28, and multiple mounting holes 29 are provided on the main air passage 28. The air inlet pipe 20 extends into the mounting hole 29. An air supply pipe 30 is installed on the main air passage 28. The air supply pipe 30 is rotatably connected to the main air passage 28. An air pump 31 is connected to the air supply pipe 30.

[0047] Each intake pipe 20 is equipped with a solenoid valve at the connection with the main air passage 28. The solenoid valve is only opened when the corresponding test channel 16 is used. Gas enters the intake pipe 20 through the gas delivery pipe 30 and the main air passage 28 for sealing test. At the same time, the gas delivery pipe 30 is rotatably connected to the main air passage 28 to avoid twisting the gas delivery pipe 30 when the rotating seat 24 rotates.

[0048] The material transfer component includes a discharge rod 32, a mounting base 33, a push rod 34, and a support plate 35;

[0049] A discharge rod 32 is provided on the side of the base 11 away from the operating table 1. A mounting base 33 is installed at the end of the discharge rod 32. Multiple push rods 34 are installed on the mounting base 33. The multiple push rods 34 are arranged in a circle on the mounting base 33. A support plate 35 is installed at the end of the push rod 34.

[0050] A displacement sensor 36 is installed on the mounting base 33, and the displacement sensor 36 is used to detect the position of the mounting base 33.

[0051] A blocking sensor is provided at one end of the discharge rod 32 near the top rod 34. Both the discharge rod 32 and the top rod 34 are telescopic rods and are electrically connected to the controller 3. After the hose is put into the clamping cylinder 2, the worker starts the clamping equipment. The discharge rod 32 extends and moves the blocking sensor toward the inlet section of the clamping cylinder 2. When the inner core contacts the blocking sensor, the blocking sensor feeds back a signal to the controller 3. The controller 3 controls the discharge rod 32 to stop moving and at the same time controls the top rod 34 to extend so that the support plate 35 supports the hose, so that the hose can be moved by the movement of the discharge rod 32.

[0052] After the crimping is completed, the discharge rod 32 retracts and moves the hose toward the detection ring 17. When the displacement sensor 36 detects that the discharge rod 32 has moved the hose seal to the detection point, it sends a signal to the controller 3 to stop the hose from moving and perform the detection. The accurate detection is that the hose and the outer sleeve are located between the front sealing ring 12 and the rear sealing ring 13, forming a sealing cavity 14, which further ensures the sealing effect and improves the detection accuracy.

[0053] Meanwhile, the discharge rod 32 can reduce the curvature of the hose, making it easier to fasten and inspect.

[0054] The clamping shaft 7 has multiple fitting grooves 37, which are conical. Multiple elastic elements 38 are installed inside the clamping tube 2. Clamping blocks 8 are installed at the ends of the elastic elements 38. The clamping blocks 8 have conical surfaces facing the fitting grooves 37 and cooperate with the conical surfaces of the fitting grooves 37 to form a clamping conical surface 9.

[0055] When the clamping shaft 7 moves to clamp the tube, the fitting groove 37 can guide and limit the clamping block 8, preventing the clamping block 8 from shaking and improving the quality of clamping.

[0056] The flow meter 21 is electrically connected to the controller 3. The controller 3 classifies the sealing performance into three levels: qualified, rework, and scrap based on the feedback from the flow meter 21.

[0057] The device determines the degree of sealing by detecting the flow meter 21. The sealing degree can be judged based on the reading of the flow meter 21. If the sealing is good, a green light will be displayed at the controller 3 and the discharge rod 32 will push out the hose. If the sealing is poor, the hose will be moved into the hose clamping cylinder 2 for pressure clamping and a yellow light will be displayed to determine if the problem is caused by insufficient clamping pressure. The yellow light can remind the staff to pay attention to the clamping and testing. If the test is qualified after clamping again, the clamping pressure needs to be adjusted or the mold needs to be replaced. For products with poor sealing, a red light will be displayed, indicating that the product is unqualified, which is convenient for workers to classify.

[0058] Working principle of the invention:

[0059] When hoses need to be crimped, the hose is placed into the crimping cylinder 2. The crimping machine is started via the operating table 1. The crimping telescopic rod 6 pushes the crimping shaft 7 towards the inlet end 4. The crimping shaft 7, through the conical surface, pushes the crimping block 8, causing the valve mold 10 to retract inward to complete the crimping. After the joint is crimped, the material transfer component moves the hose to the testing point. When it is moved to the testing point, the front sealing ring 12, the rear sealing ring 13, and the hose cooperate to form a sealing cavity 14. Gas is introduced into the sealing cavity 14 through the constant pressure valve 15. If the sealing is poor, a large amount of gas will always pass through the constant pressure valve 15. If the sealing is good, there will be no gas or only a small amount of gas passing through the constant pressure valve 15. This method is used to test the sealing performance. The sealing performance of the hose is tested directly after crimping. On the one hand, it saves the time of transferring the crimped hose to the sealing performance test point, improving production efficiency. On the other hand, if the sealing performance of a batch of products is poor, the workers can repair the crimping machine in time, avoiding a large number of defective products and improving production quality.

[0060] During testing, controller 3 controls the extension of the sealing telescopic rod 18, which pushes the arc plate 19 to make the front sealing ring 12 tightly adhere to the hose and the rear sealing ring 13 tightly adhere to the outer sleeve, forming a sealing cavity 14 between the front sealing ring 12, the rear sealing ring 13, the hose, and the outer sleeve. After controller 3 controls the extension of the sealing telescopic rod 18, controller 3 controls the input of gas into the sealing cavity 14. Due to the constant pressure valve 15, the gas pressure in the sealing cavity 14 should be the same as the set pressure of the constant pressure valve 15. When the seal is good, the flow meter 21 detects that there is no or only a small amount of gas passing through the flow meter 21. When the seal is poor, due to gas leakage, the gas pressure in the sealing cavity 14 can never reach the specified gas pressure, and the flow meter 21 detects that a large amount of gas continuously passes through the constant pressure valve 15. Through this precise detection by the flow meter 21, the seal can be accurately judged, the test results are more accurate, and the quality of the hose clamping is further guaranteed.

[0061] The front sealing ring 12 and rear sealing ring 13 of the seals in different detection channels 16 have different specifications. When it is necessary to perform tube clamping and testing on hoses of different sizes, the controller 3 is used for adjustment. The controller 3 will start the drive motor 27 to drive the drive gear 26 to rotate. The drive gear 26, due to its meshing with the meshing gear 25, drives the rotating seat 24 to rotate, so that the corresponding detection channel 16 is aligned with the tube clamping cylinder 2, ensuring the sealing performance of the sealing cavity 14, ensuring the accuracy of the test results, and avoiding the complicated steps of changing the test pieces for hoses of different sizes, shortening the testing time and improving efficiency.

[0062] A blocking sensor is provided at one end of the discharge rod 32 near the top rod 34. Both the discharge rod 32 and the top rod 34 are telescopic rods and are electrically connected to the controller 3. After the hose is put into the clamping cylinder 2, the worker starts the clamping equipment. The discharge rod 32 extends and moves the blocking sensor toward the inlet section of the clamping cylinder 2. When the inner core contacts the blocking sensor, the blocking sensor feeds back a signal to the controller 3. The controller 3 controls the discharge rod 32 to stop moving and at the same time controls the top rod 34 to extend so that the support plate 35 supports the hose, so that the hose can be moved by the movement of the discharge rod 32.

[0063] After the crimping is completed, the discharge rod 32 retracts and moves the hose toward the detection ring 17. When the displacement sensor 36 detects that the discharge rod 32 has moved the hose seal to the detection point, it sends a signal to the controller 3 to stop the hose from moving and perform the detection. The accurate detection is that the hose and the outer sleeve are located between the front sealing ring 12 and the rear sealing ring 13, forming a sealing cavity 14, which further ensures the sealing effect and improves the detection accuracy.

[0064] Meanwhile, the discharge rod 32 can reduce the curvature of the hose, making it easier to fasten and inspect.

[0065] The device determines the degree of sealing by detecting the flow meter 21. The sealing degree can be judged based on the reading of the flow meter 21. If the sealing is good, a green light will be displayed at the controller 3 and the discharge rod 32 will push out the hose. If the sealing is poor, the hose will be moved into the hose clamping cylinder 2 for pressure clamping and a yellow light will be displayed to determine if the problem is caused by insufficient clamping pressure. The yellow light can remind the staff to pay attention to the clamping and testing. If the test is qualified after clamping again, the clamping pressure needs to be adjusted or the mold needs to be replaced. For products with poor sealing, a red light will be displayed, indicating that the product is unqualified, which is convenient for workers to classify.
