Description

Technical Field

[0001] The present invention relates to the technical field related to hose joint assembly, and in particular to a joint assembly device for connecting metal hoses. Background Art

[0002] Metal hoses are essential components in the connection lines of modern industrial equipment. They are used as protective conduits for wires, cables, and automated instrument signals, as well as for residential showers. Available in sizes ranging from 3mm to 150mm, they are a common component in residential showers, primarily used for mid-connections between faucets and main water lines.

[0003] In the prior art, according to actual usage requirements, in some cases, it is necessary to connect a plastic flexible pipe to the end of a metal hose and assemble a joint on the end of the plastic flexible pipe. However, the assembly of the joint and the flexible pipe is mostly done manually, which is time-consuming and labor-intensive, inconvenient to operate, and not conducive to improving production efficiency. Summary of the Invention

[0004] The present invention aims to overcome the drawback in the prior art that the assembly of joints and flexible pipes is mostly done manually, which is not conducive to improving production efficiency, and provides a joint assembly device for connecting metal flexible pipes that is conducive to improving production efficiency.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A joint assembly device for connecting a metal hose, which includes a workbench and a linear cylinder. The workbench is provided with a clamping cylinder, a limit plate, a left clamping block and a right clamping block. The clamping cylinder is detachably connected to the workbench, and the limit plate is located at the front side of the clamping cylinder and is slidably connected to the workbench up and down. The left clamping block and the right clamping block are both located at the rear side of the clamping cylinder. The left clamping block is fixedly connected to the workbench and is located on one side of the right clamping block. The telescopic end of the linear cylinder is connected to the other side corresponding to the right clamping block. The right clamping block is slidably connected to the workbench left and right under the drive of the linear cylinder. A clamping area is formed between the left clamping block and the right clamping block. A linear cylinder is provided on the side of the workbench. A plug-in shaft corresponding to the clamping area is connected to the output end of the linear cylinder, and the limit plate is located between the clamping cylinder and the plug-in shaft.

[0007] The workbench is provided with a clamping cylinder, a limit plate, a left clamping block and a right clamping block. The clamping cylinder is detachably connected to the workbench, the limit plate is located at the front side of the clamping cylinder and is connected to the workbench for up and down sliding, the left clamping block and the right clamping block are both located at the rear side of the clamping cylinder, the left clamping block is fixedly connected to the workbench and is located on one side of the right clamping block, the telescopic end of the linear cylinder one is connected to the other side corresponding to the right clamping block, and the right clamping block is connected to the workbench for left and right sliding under the drive of the linear cylinder one, and a clamping area is formed between the left clamping block and the right clamping block, and a linear cylinder two is provided on the side of the workbench, and a plug-in shaft corresponding to the clamping area is connected to the output end of the linear cylinder two, and the limit plate is located between the clamping cylinder and the plug-in shaft. After the joint is sorted by the vibration plate, it is placed on the plug-in shaft through the mechanical glove; after the flexible tube enters the clamping area and its end rests on the limit plate, the control system controls the linear cylinder one to work, driving the right clamping block to slide toward the left clamping block, so that the left clamping block and the right clamping block are clamped on the left and right sides of the flexible tube respectively. At the same time, the control system controls the clamping claw cylinder to clamp the end of the flexible tube, and the limit plate moves down, so that the end of the flexible tube is separated from the limit plate. The control system controls the linear cylinder two to work, so that the plug-in shaft advances and is inserted into the flexible tube, facilitating the insertion of the joint into the end of the flexible tube, so that the joint and the flexible tube are assembled. Finally, the plug-in shaft retreats and is separated from the flexible tube under the drive of the linear cylinder two. This equipment replaces pure manual assembly, saves time and effort, and is beneficial to saving labor while achieving the purpose of improving production efficiency; the limit plate is conducive to ensuring the relative position accuracy between the flexible tube and the plug-in shaft, thereby ensuring the assembly accuracy between the joint and the flexible tube. Compared with manual assembly, product quality is further improved.

[0008] Preferably, it further includes a linear cylinder three, which is detachably connected to the outer wall of the linear cylinder one, a slot matching the limit plate is provided on the workbench, a connecting shaft is provided on the limit plate, a connecting block is provided on the output end of the linear cylinder three, and the limit plate is fixedly connected to the connecting block via the connecting shaft and is slidably connected to the slot up and down under the drive of the linear cylinder three. The control system controls the linear cylinder three to move the limit plate up or down, which is beneficial for the assembly process to be carried out in sequence according to the set program, and replaces manual operation with programmed control, which is beneficial for improving assembly accuracy and work efficiency. The limit plate matches the slot, which, on the one hand, ensures that the bottom of the limit plate is always located in the slot, which is beneficial for improving safety performance. On the other hand, it is beneficial for ensuring the connection strength and position accuracy of the limit plate, thereby ensuring the assembly accuracy between the joint and the flexible pipe.

[0009] Preferably, one side of the limit plate is close to the clamping cylinder, and the other side of the limit plate is away from the clamping cylinder. A sensor is provided on the side of the limit plate close to the clamping cylinder. The sensor is detachably connected to the top of the limit plate. The sensor is electrically connected to the clamping cylinder and the linear cylinder three respectively. The bottom of the limit plate is connected to the slot for sliding up and down under the drive of the linear cylinder three. The connecting shaft is fixedly connected to the side of the limit plate away from the clamping cylinder. When the end of the flexible pipe abuts against the limit plate, the sensor receives a signal and transmits it to the control system. The control system controls the operation of the clamping cylinder and the linear cylinder three, so that the clamping cylinder clamps the end of the flexible pipe while the linear cylinder three drives the limit plate downward until the limit plate and the end of the flexible pipe are separated from each other. The response is timely and sensitive, which is conducive to improving production efficiency.

[0010] Preferably, one end of the splice shaft is fixedly connected to the output end of the second linear cylinder. The diameter of the splice shaft at the end fixedly connected to the output end of the second linear cylinder is larger than the diameter of the other end, forming a stepped surface. The other end of the splice shaft is provided with a guide head. The guide head provides a good guide for the joint to be smoothly mounted on the splice shaft, and the stepped surface provides a good position limit for the joint to be inserted into the flexible pipe.

[0011] Preferably, one side of the right clamping block is close to the left clamping block, and the other side corresponding to the right clamping block is away from the left clamping block and is detachably connected to the telescopic end of the linear cylinder 1. The right clamping block is provided with a protrusion on the side close to the left clamping block, and the protrusion is fixedly connected to the top of the right clamping block. The left clamping block is provided with an L-shaped groove matching the protrusion, and one side of the L-shaped groove is in a vertical state up and down, and the clamping area is located between the side of the L-shaped groove in a vertical state up and down and the protrusion, and conveying mechanisms are provided on the left and right sides of the clamping area, and the other side of the L-shaped groove is horizontal and provided with a proximity switch, and the proximity switch is electrically connected to the linear cylinder 1, and the other end of the L-shaped groove is close to the limit plate, and the proximity switch is detachably connected to the end of the L-shaped groove away from the limit plate. The clamping area is located between one side of the L-shaped groove in a vertical state and the protrusion, which plays a certain role in limiting the flexible tube; when the proximity switch senses that there is a flexible tube in the clamping area, it sends a signal to the control system, which controls the linear cylinder to work, driving the right clamping block to slide toward the left clamping block, so that the left clamping block and the right clamping block are clamped on the left and right sides of the flexible tube respectively, and then the conveying mechanism conveys the flexible tube forward until the end of the flexible tube contacts the limit plate; in this solution, if the end of the flexible tube is manually pressed against the limit plate, due to the fast reaction speed of the clamping cylinder, it often causes differences in the force exerted by the end of the flexible tube on the limit plate, thereby This results in differences in the assembly accuracy of the joint and the flexible tube. In order to solve this technical problem, the flexible tube enters from the end of the clamping area away from the limit plate and is output from the end close to the limit plate. During this process, the flexible tube is conveyed at a uniform speed by the conveying mechanism. The control system can accurately calculate the time from the start to the end of the conveying of the flexible tube according to the conveying speed of the conveying mechanism and the distance between the end of the clamping area away from the limit plate and the limit plate, or transmit a signal to the control system through a sensor, so as to more accurately control the operation of the clamping cylinder, so that the force exerted on the limit plate by the end of each flexible tube is basically the same, thereby helping to improve the assembly accuracy of the joint and the flexible tube.

[0012] Preferably, the protrusion and the L-shaped groove are provided with a mounting groove matching the conveying mechanism on one side of the vertical state, and the conveying mechanism includes two transmission shafts, which are respectively vertically mounted on the front and rear ends of the mounting groove, and the transmission shaft is rotatably connected to the side wall of the mounting groove. A conveyor belt is provided on the transmission shaft, and the two ends of the conveyor belt are respectively sleeved on the two transmission shafts. The conveying surface of the conveyor belt is provided with a limit groove corresponding to the plug-in shaft. A servo motor is detachably mounted on the left clamping block, and the output end of the servo motor is fixedly connected to the end of one of the transmission shafts. When the left clamping block and the right clamping block are respectively clamped on the left and right sides of the flexible pipe, the left and right sides of the flexible pipe are respectively limited in the limit grooves of the corresponding conveyor belts, so that the flexible pipe is continuously straightened by the limit grooves during the conveying process, so that the end of the flexible pipe can always correspond to the plug-in shaft, which is conducive to ensuring the assembly accuracy of the joint and the flexible pipe.

[0013] Preferably, it also includes a feeder, said feeder being located at the rear side of the left clamping block, said clamping cylinder being located at the front side of the left clamping block, said feeder comprising a support platform, said support platform having a V-shaped hopper overhead arranged on the top of said support platform, said hopper being provided with a plurality of parallel flexible pipes, said hopper being provided with a feed port at the top of said hopper, and a discharge port matching the flexible pipes at the bottom of said hopper, said splints being provided on the left and right sides of said discharge port, and the area formed between the two splints being connected to the clamping area correspondingly, said splint being located outside the hopper, and said support platform being provided with two driving mechanisms respectively matching the two splints, said driving mechanism being connected with the corresponding splints, said splint being provided with a torsion spring shaft at the top, said splint being rotatably connected to the edge of the discharge port by the torsion spring shaft under the drive of the corresponding driving mechanism, and said bottom of said splint being provided with an avoidance notch matching the bottom of the driving mechanism, said flexible pipe slides toward the clamping area under the drive of the driving mechanism, and said plug-in shaft is sleeved with a joint matching the flexible pipe. The V-shaped hopper makes it possible for the flexible tube inside it to continuously discharge materials from the discharge port under the action of its own gravity; the two driving mechanisms work simultaneously, causing the two clamping plates to rotate outward under the resetting action of the torsion spring shaft, and the two clamping plates open, so that the flexible tube at the bottom of the hopper can fall from the discharge port to the support platform, and the two driving mechanisms continue to work simultaneously, and overcome the force of the torsion spring shaft to cause the two clamping plates to rotate inward and move closer to each other, preventing the flexible tube at the bottom of the hopper from continuing to fall from the discharge port. At the same time, the flexible tube located on the support platform slides toward the clamping area under the driving action of the driving mechanism, so that one end of the flexible tube enters the end of the L-shaped groove away from the limit plate. At this time, the proximity switch located in the end of the L-shaped groove away from the limit plate receives a signal and sends a signal to the control system. The control system controls the linear cylinder to work, and at the same time, the flexible tube continues to be transported through the conveying mechanism, thereby replacing the manual placement of the flexible tube, further improving the assembly accuracy and work efficiency of the joint and the flexible tube.

[0014] Preferably, the two driving mechanisms are symmetrically distributed with the discharge port as the center, and the driving mechanism includes a driving motor and two eccentric wheels with the same eccentricity. The driving motor is detachably connected to the bottom of the support platform, and the eccentric wheels are located on the top of the support platform. The output shaft of the driving motor passes through the support platform and is connected to the two eccentric wheels respectively, one of the eccentric wheels is close to the support platform and matches the avoidance gap, and the other eccentric wheel is away from the support platform and in contact with the splint. The driving motors on the two driving mechanisms work to drive the two eccentric wheels on their output shafts to rotate synchronously; when the short radius of the eccentric wheel gradually approaches the splint, the two splints gradually rotate outward and open under the resetting action of the torsion spring shaft, so that the flexible tube at the bottom of the hopper can fall from the discharge port to the support platform; the two driving mechanisms continue to work simultaneously, and when the long radius of the eccentric wheel gradually approaches the splint, the eccentric wheel away from the support platform acts on the corresponding splint and overcomes the force of the torsion spring shaft to make the two splints rotate inward and move closer to each other, preventing the flexible tube at the bottom of the hopper from continuing to fall from the discharge port. At the same time, the eccentric wheels close to the support platform on the two driving mechanisms rotate toward each other and contact the left and right side walls of the flexible tube located on the support platform through the avoidance gap to drive the flexible tube to slide toward the clamping area. Therefore, through the structural design of the driving mechanism, on the one hand, the opening and closing of the two splints is realized, and on the other hand, the transportation of the flexible tube is realized, and the structure is simple.

[0015] Preferably, one side of the splint is close to the eccentric wheel, and the other side of the splint is away from the eccentric wheel. The splint is bent from the side close to the eccentric wheel to the other side thereof to form a V-shaped structure and a fold line is formed in the middle of the splint. The eccentric wheel is located below the fold line, and the discharge port is located above the fold line. The minimum gap formed at the fold line of the two splints is smaller than the diameter of the flexible tube, and the maximum gap formed at the fold line of the two splints is larger than the diameter of the flexible tube and smaller than twice the diameter of the flexible tube. The shape design of the splints makes the top and bottom of the two splints form a trumpet-mouth structure, which makes it convenient for the eccentric wheel to drive the splints to rotate to realize the discharge control of the flexible tube; the minimum gap formed at the fold line of the two splints is smaller than the diameter of the flexible tube, so that when the two splints are close to each other, the flexible tube at the bottom of the hopper can be prevented from falling from the discharge port; the maximum gap formed at the fold line of the two splints is larger than the diameter of the flexible tube and smaller than twice the diameter of the flexible tube, so that when the two splints are opened to each other, it is convenient to limit the flexible tube at the bottom of the hopper from falling from the discharge port to the support platform, thereby facilitating the orderly transportation of the flexible tube.

[0016] Preferably, a plurality of balls are embedded in the top of the support platform, located on the centerline between the two clamping plates and evenly distributed along the length of the clamping plates. When the balls fall onto the support platform and come into contact with the balls, friction between the flexible pipe and the support platform is reduced, thereby facilitating smooth delivery of the flexible pipe under the action of the eccentric wheel.

[0017] The beneficial effects of the present invention are: saving time and effort, which is beneficial to saving labor while achieving the purpose of improving production efficiency; it is beneficial to ensuring and improving the assembly accuracy between the joint and the flexible tube, and compared with manual assembly, the product quality is further improved; the limit plate matches the slot, on the one hand, so that the bottom of the limit plate is always located in the slot, which is beneficial to improving safety performance, and on the other hand, it is beneficial to ensure the connection strength and position accuracy of the limit plate, thereby helping to ensure the assembly accuracy between the joint and the flexible tube; the response is timely and sensitive; the structural design of the driving mechanism on the feeder, on the one hand, realizes the opening and closing of the two splints, on the other hand, realizes the transportation of the flexible tube, and has a simple structure; it is beneficial to realize the orderly transportation of the flexible tube; it is beneficial to reduce the friction between the flexible tube and the support platform, so that the flexible tube can be smoothly output under the action of the eccentric wheel.

The feeder 23 includes a support platform 24, and a V-shaped hopper 25 is overhead on the top of the support platform 24. A plurality of parallel soft pipes 26 are provided in the hopper 25, and a feed port 27 is provided at the top of the hopper 25. A discharge port matching the soft pipe 26 is provided at the bottom of the hopper 25, and a splint 28 is provided on both sides of the discharge port. The area formed between the two splints 28 is connected to the clamping area 7. The splint 28 is located at the top of the hopper 25. Outside the hopper 25, two driving mechanisms 29 are provided on the support platform 24, which are matched with the two splints 28 respectively. The top of the driving mechanism 29 is connected to the corresponding splint 28. A torsion spring shaft is provided on the top of the splint 28. The splint 28 is rotatably connected to the edge of the discharge port through the torsion spring shaft under the drive of the corresponding driving mechanism 29. The bottom of the splint 28 is provided with an avoidance notch 30 that matches the bottom of the driving mechanism 29. The flexible pipe 26 slides toward the clamping area 7 under the drive of the driving mechanism 29, and a joint 31 that matches the flexible pipe 26 is sleeved on the plug-in shaft 9.

[0033] like Figure 4 、 Figure 5 and Figure 6 As shown, the two driving mechanisms 29 are symmetrically distributed with the discharge port as the center. The driving mechanism 29 includes a driving motor and two eccentric wheels 32 with the same eccentricity. The driving motor is detachably connected to the bottom of the support platform 24. The eccentric wheels 32 are located on the top of the support platform 24. The output shaft of the driving motor passes through the support platform 24 and is connected to the two eccentric wheels 32 respectively. One of the eccentric wheels 32 is close to the support platform 24 and matches the avoidance gap 30, and the other eccentric wheel 32 is away from the support platform 24 and contacts with the splint 28.

[0034] like Figure 4 、 Figure 5 and Figure 6 As shown, one side of the splint 28 is close to the eccentric wheel 32, and the other side of the splint 28 is away from the eccentric wheel 32. The splint 28 is bent from the side close to the eccentric wheel 32 to the other side to form a V-shaped structure, and a fold line is formed in the middle of the splint 28. The eccentric wheel 32 is located below the fold line, and the discharge port is located above the fold line. The minimum gap formed by the fold line of the two splints 28 is smaller than the diameter of the flexible pipe 26, and the maximum gap formed by the fold line of the two splints 28 is larger than the diameter of the flexible pipe 26 and smaller than twice the diameter of the flexible pipe 26. A plurality of balls 33 are embedded in the top of the support platform 24. The balls 33 are located on the center line between the two splints 28 and are evenly distributed along the length of the splint 28.

[0035] The joint 31 is arranged on the plug-in shaft 9 through the mechanical glove after being sorted by the vibrating disk; the control system controls the driving motors on the two driving mechanisms 29 to work, so as to drive the two eccentric wheels 32 on their corresponding output shafts to rotate synchronously; when the short radius of the eccentric wheel 32 gradually approaches the splint 28, the two splints 28 gradually rotate outward and open under the reset action of the torsion spring shaft, so that the flexible pipe 26 at the bottom of the hopper 25 falls from the discharge port to the support platform 24; the two driving motors continue to work simultaneously, and when the long radius of the eccentric wheel 32 gradually approaches the splint 28, on the one hand, the eccentric wheels 32 on the two driving mechanisms 29 away from the support platform 24 rotate towards each other and act On the corresponding clamping plates 28, the force of the torsion spring shaft is overcome so that the two clamping plates 28 rotate inward and move closer to each other, so as to prevent the flexible pipe 26 at the bottom of the hopper 25 from continuing to fall from the discharge port; at the same time, on the other hand, the eccentric wheels 32 on the two driving mechanisms 29 close to the support platform 24 rotate towards each other and contact the left and right side walls of the flexible pipe 26 on the support platform 24 through the avoidance gap 30, and drive the flexible pipe 26 to slide toward the clamping area 7 through the friction effect; so that one end of the flexible pipe 26 enters the end of the L-shaped groove 17 away from the limit plate 4. At this time, the proximity switch located in the end of the L-shaped groove 17 away from the limit plate 4 receives a signal, The control system controls the linear cylinder 2 to work, driving the right clamping block 6 to slide toward the left clamping block 5, so that the conveyor belts 20 on the left and right clamping blocks 5 and 6 are clamped on the left and right sides of the flexible pipe 26 respectively, and the left and right sides of the flexible pipe 26 are respectively limited in the limiting grooves 21 of the corresponding conveyor belt 20; the control system controls the servo motor 22 to work, so that the conveyor belts 20 on the left and right clamping blocks 5 and 6 are driven in opposite directions to convey the flexible pipe 26 forward; when the end of the flexible pipe 26 abuts against the limiting plate 4, the induction The device receives the signal and transmits it to the control system, which controls the operation of the clamping cylinder 3 and the linear cylinder 3 10, so that the clamping cylinder 3 clamps the end of the flexible tube 26 while the linear cylinder 3 10 drives the limit plate 4 to move downward until the limit plate 4 and the end of the flexible tube 26 are separated from each other; the control system controls the linear cylinder 2 8 to operate, so that the plug-in shaft 9 moves forward and is inserted into the flexible tube 26; finally, the plug-in shaft 9 retreats under the drive of the linear cylinder 2 8 and is separated from the flexible tube 26, and the joint 31 and the flexible tube 26 are assembled.

[0036] In this solution, if the end of the flexible tube 26 is manually pressed against the limit plate 4, due to the fast reaction speed of the clamping cylinder 3, there will often be differences in the force exerted by the end of the flexible tube 26 on the limit plate 4, which will lead to differences in the assembly accuracy of the joint 31 and the flexible tube 26. In order to solve this technical problem, the flexible tube 26 enters from the end of the clamping area 7 away from the limit plate 4 and outputs from the end close to the limit plate 4. During this process, the flexible tube 26 is conveyed at a uniform speed by the conveying mechanism 18. The control system can accurately calculate the time from the start to the end of the conveying of the flexible tube 26 according to the conveying speed of the conveying mechanism 18 and the distance between the end of the clamping area 7 away from the limit plate 4 and the limit plate 4, or transmit a signal to the control system through the sensor, so as to more accurately control the operation of the clamping cylinder 3, so that the force exerted by the end of each flexible tube 26 on the limit plate 4 is basically the same, thereby helping to improve the assembly accuracy of the joint 31 and the flexible tube 26.
