Description

Technical Field

[0001] This invention relates to the field of hose fitting processing technology, specifically to a hydraulic hose and fitting crimping device with a precise mating structure. Background Technology

[0002] Hydraulic hoses, also known as hydraulic flexible hoses, are piping devices used to transport liquids. They consist of an inner rubber layer, a reinforcing layer, and an outer rubber layer. The inner rubber layer is made of synthetic rubber or synthetic rubber with good hydraulic oil resistance. The reinforcing layer is usually made of steel wire braiding or high-strength steel wire sheathing. The outer rubber layer is usually made of synthetic rubber, nitrile rubber, or polyurethane. This design gives hydraulic hoses corrosion resistance, high strength, and wear resistance. Hydraulic hoses are widely used in machinery, construction, mining, and agriculture, mainly for transporting water, oil, gas, and various liquids. They can withstand high pressure and have a wide operating temperature range. Hydraulic hoses are characterized by high strength, long service life, and good adaptability, ensuring the normal operation of power machinery and engineering equipment and reducing downtime caused by pipeline damage. Hydraulic hoses play a very important role in the operation of machinery or engineering equipment, responsible for transporting liquid media to various parts and ensuring the normal operation of various hydraulic components. If the quality of the hydraulic hose is poor, it can lead to problems such as pipe bursting and leakage, which can seriously affect the service life of the equipment. Therefore, selecting high-quality hydraulic hoses is crucial.

[0003] Hydraulic hoses generally do not leak when the material strength meets the design standards. However, the connection between the hydraulic hose and the equipment requires the use of a connector. Since the connector is made of metal, it cannot be integrally formed with the hydraulic hose and must be manufactured through assembly. However, during the assembly process, it is impossible to ensure that the connector and the hose are aligned correctly, resulting in high friction during installation and damage to the inner wall of the hose opening due to misalignment, which affects the normal use of the hydraulic hose. Summary of the Invention

[0004] The purpose of this invention is to provide a hydraulic hose and connector crimping device with a precise docking structure to solve the problem of poor installation method of hydraulic hose and connector mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hydraulic hose and connector crimping device with a precise docking structure, comprising a protective shell, a central disk rotatably mounted on one outer surface of the protective shell, and a hydraulic hose mounting disk fixedly mounted on the side surface of the central disk, with a groove formed on the side surface of the hydraulic hose mounting disk, a limit rod engaging with the side surface of the hydraulic hose mounting disk, and the limit rod being fixedly mounted to the hydraulic hose mounting disk by fixing bolts, a switching motor fixedly mounted on the side surface of the protective shell, and the output shaft of the switching motor penetrating the side surface of the protective shell and fixedly connected to the central disk, and a locking mechanism provided on one side of the protective shell, which performs precise docking and prevents misalignment-induced insertion abnormalities by power-off self-locking.

[0006] Preferably, the locking mechanism includes: a positioning groove formed on the side surface of the hydraulic hose mounting disc; a lateral mounting seat fixedly provided on the side surface of the protective housing; a sliding alignment positioning block installed on the outer surface of the lateral mounting seat; a limit plate fixedly provided on the outer surface of one end of the alignment positioning block; a sliding locking plate installed on the outer surface of the lateral mounting seat; an abutment plate fixedly provided at the upper end of the locking plate; a displacement electromagnet fixedly provided on the lower surface of the abutment plate; and a fixing electromagnet and a first contact switch fixedly provided on the upper surface of the lateral mounting seat.

[0007] The above technical solution enables the hydraulic hose mounting plate to achieve self-locking after it is moved into place, ensuring precise docking.

[0008] Preferably, the end of the alignment positioning block facing the hydraulic hose mounting plate is an isosceles trapezoidal design, and a spring connects the alignment positioning block and the side mounting seat. The alignment positioning block is installed by engaging with a retaining plate and a clamping plate, and the retaining plate is a semi-circular design. A spring connects the contact plate and the side mounting seat. The displacement electromagnet is located directly above the fixed electromagnet, and the magnetic poles of the opposite ends of the displacement electromagnet and the fixed electromagnet are the same. Furthermore, the sum of the thicknesses of the displacement electromagnet and the fixed electromagnet is less than the vertical height between the upper end of the first contact switch and the upper end of the side mounting seat.

[0009] The above technical solution enables the first contact switch to be pressed after the contact plate falls normally.

[0010] Preferably, the inner side of the protective shell is provided with a clamping mechanism, and the feeding rhythm is controlled by the position of the clamping mechanism.

[0011] By adopting the above technical solution, the hose can be stably clamped and damage to the hose caused by misalignment can be prevented.

[0012] Preferably, the clamping mechanism includes: a support plate, which is fixedly disposed on the inner surface of the protective shell, and a limiting hydraulic rod is fixedly installed on the lower surface of the support plate and the inner bottom surface of the protective shell. A sliding seat is fixedly disposed at one end of the limiting hydraulic rod, and a sliding clamping plate is installed at one end of the sliding seat.

[0013] The above technical solution enables the clamping plate to slide and retract when subjected to excessive pressure, thus preventing damage to the hose.

[0014] Preferably, the two limiting hydraulic rods are arranged facing each other, a spring is connected between the sliding seat and the clamping plate, and the outer surfaces of the two sliding seats facing each other are in contact with each other, and the outer surfaces of the two clamping plates facing each other are in contact with each other.

[0015] By adopting the above technical solution, the clamping plates can ensure stable clamping of the hose by fitting together with each other.

[0016] Preferably, the lower end of the protective shell is provided with a feeding mechanism, which simultaneously performs the crimping and feeding of the joint by rotation.

[0017] By adopting the above technical solution, the pressing and feeding of the joint can be carried out simultaneously, thereby improving the overall processing efficiency.

[0018] Preferably, the feeding mechanism includes: a side support plate, the side support plate being fixedly disposed on the inner surface of the protective shell, a feeding motor being fixedly installed on the outer surface of the side support plate, and a feeding tray being fixedly connected to one end of the output shaft of the feeding motor, and a magnetic mounting bracket being fixedly disposed on the side surface of the feeding tray, an ejection hydraulic rod being fixedly installed on the upper side surface of the side support plate, a feeding hydraulic rod being fixedly disposed on the lower end surface of the protective shell, and a feeding rod being fixedly connected to one end of the feeding hydraulic rod, and a feeding cylinder being fixedly disposed on the lower end surface of the protective shell.

[0019] By adopting the above technical solution, the feeding cylinder can be replenished with materials through the automatic falling of the joint.

[0020] Preferably, the magnetic mounting brackets are evenly distributed on the outer surface of the feeding tray facing the clamping plate, one end of the ejecting hydraulic rod is positioned directly opposite the clamping plate, the lower end side surface of the feeding cylinder has a circular opening, and the upper end of the feeding cylinder is also open, the feeding rod is positioned directly opposite the circular opening on the lower end side surface of the feeding cylinder, and the end of the feeding rod facing the feeding cylinder is frustum-shaped.

[0021] By adopting the above technical solution, the feeding rod will not get stuck with the falling joint above when it pushes out the lower joint, thus preventing it from moving.

[0022] Preferably, a third contact switch is fixedly installed on the side surface of the support plate, a second contact switch is fixedly installed on the outer surface of the limiting hydraulic rod, and a trigger plate is fixedly installed on the outer surface of the upper limiting hydraulic rod connected to the sliding seat, with the trigger plate located between the second contact switch and the third contact switch.

[0023] By adopting the above technical solution, the trigger plate can trigger the second contact switch and the third contact switch at different times by moving up and down.

[0024] Compared with the prior art, the beneficial effects of the present invention are: the hydraulic hose and connector crimping device with a precise docking structure:

[0025] 1. By switching off the motor and self-locking the hydraulic hose mounting plate after the locking mechanism rotates to the correct position, the hydraulic hose mounting plate can ensure that one end of the hydraulic hose is facing the connector to be installed, thus ensuring that the connector and the hydraulic hose can be installed facing each other without damaging the inner wall of the hydraulic hose.

[0026] 2. Furthermore, by clamping the hose with a clamping plate, the clamping plate can slide when the clamp is misaligned with the hose, so that the hose will not be damaged by the connector. By changing the spring stiffness, targeted adjustments can be made for hoses of different materials.

[0027] 3. Furthermore, by rotating the feeding plate in conjunction with the ejection hydraulic rod and the feeding hydraulic rod, the connector to be installed can be automatically fed. This is controlled in conjunction with the movement of the sliding seat, eliminating the need for complex programming control. This allows the feeding plate, ejection hydraulic rod, and feeding hydraulic rod to work automatically in sequence. Attached Figure Description

[0039] 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.

[0040] Please see Figure 1-10 The present invention provides a technical solution: a hydraulic hose and connector crimping device with a precise docking structure.

[0041] Example 1

[0042] This embodiment discloses: a protective shell 1, a central disk 2 rotatably mounted on one outer surface of the protective shell 1, and a hydraulic hose mounting disk 3 fixedly mounted on the side surface of the central disk 2, and a groove opened on the side surface of the hydraulic hose mounting disk 3, a limit rod 4 engaging with the side surface of the hydraulic hose mounting disk 3, and the limit rod 4 being fixedly mounted to the hydraulic hose mounting disk 3 by fixing bolts 5, a switching motor 6 fixedly mounted on the side surface of the protective shell 1, and the output shaft of the switching motor 6 passing through the side surface of the protective shell 1 and fixedly connected to the central disk 2, and a locking mechanism provided on one side of the protective shell 1, which performs precise docking and prevents misalignment-induced insertion abnormalities by power-off self-locking;

[0043] The locking mechanism includes: a positioning groove 7, which is opened on the side surface of the hydraulic hose mounting plate 3; a lateral mounting seat 8 is fixedly provided on the side surface of the protective shell 1; a sliding alignment positioning block 9 is installed on the outer surface of the lateral mounting seat 8; a limit plate 10 is fixedly provided on the outer surface of one end of the alignment positioning block 9; a sliding locking plate 11 is installed on the outer surface of the lateral mounting seat 8; a contact plate 12 is fixedly provided on the upper end of the locking plate 11; a displacement electromagnet 13 is fixedly provided on the lower surface of the contact plate 12; and a fixing electromagnet 14 and a first contact switch 15 are fixedly provided on the upper end face of the lateral mounting seat 8.

[0044] The aligning positioning block 9 has an isosceles trapezoidal design at one end facing the hydraulic hose mounting plate 3, and a spring connects the aligning positioning block 9 and the side mounting base 8. The aligning positioning block 9 is installed by engaging with the clamping plate 11 through the limiting plate 10, and the clamping plate 11 has a semi-circular design. A spring connects the contact plate 12 and the side mounting base 8. The displacement electromagnet 13 is located directly above the fixed electromagnet 14, and the magnetic poles of the opposite ends of the displacement electromagnet 13 and the fixed electromagnet 14 are the same. Furthermore, the sum of the thicknesses of the displacement electromagnet 13 and the fixed electromagnet 14 is less than the vertical height between the upper end of the first contact switch 15 and the upper end of the side mounting base 8.

[0045] During processing, the hydraulic hose to be processed is first wound up and placed inside the hydraulic hose mounting plate 3. One end of the hydraulic hose to be installed is extended a certain length through the groove on the side surface of the hydraulic hose mounting plate 3. Then, the limiting rod 4 is engaged with the hydraulic hose mounting plate 3 and fixed to the hydraulic hose mounting plate 3 by the fixing bolt 5. Then, the switching motor 6 is started to drive the center plate 2 and the hydraulic hose mounting plate 3 to rotate relative to the protective shell 1. At this time, the hydraulic hose mounting plate 3 drives the hydraulic hose to rotate into the protective shell 1. At the same time, the hydraulic hose mounting plate 3 rotates upward and presses the inclined surface of the alignment positioning block 9, so that the alignment positioning block 9 slides and stretches the spring between the alignment positioning block 9 and the side mounting seat 8 until the positioning groove 7 on the side surface of the upward rotating hydraulic hose mounting plate 3 is aligned with the alignment positioning block 9. Under the pull of the spring, the alignment positioning block 9 slides through the inclined surface and engages with the positioning groove 7 to position the hydraulic hose mounting plate 3. At this time, the switching motor 6, the displacement electromagnet 13 and the fixing electromagnet 14 are disconnected. Under the influence of gravity and the pull of the spring between the lateral mounting base 8, the clamping plate 11 slides and engages with the limiting plate 10, preventing the alignment positioning block 9 from sliding laterally and maintaining a stable limit on the hydraulic hose mounting plate 3. At the same time, the contact plate 12 slides down and presses to trigger the first contact switch 15. The first contact switch 15 sends an electrical signal to the microcontroller of the switching motor 6. At this time, the microcontroller of the switching motor 6 does not operate. When the switching motor 6 stops working after power failure and does not receive an electrical signal from the first contact switch 15 for a period of time, it indicates that the alignment positioning block 9 has not been fully engaged in the positioning groove 7, causing the clamping plate 11 to be blocked by the limiting plate 10 and unable to fall completely. The microcontroller of the switching motor 6 controls the switching motor 6 to start and drive the center plate 2 and the hydraulic hose mounting plate 3 to perform continuous forward and reverse micro-movements, so that the alignment positioning block 9, which has not been engaged in the positioning groove 7, is engaged in the positioning groove 7, allowing the clamping plate 11 to fall and lock the alignment positioning block 9, ensuring that the hydraulic hose mounting plate 3 rotates into place.

[0046] Example 2

[0047] This embodiment discloses, based on embodiment 1, that: a clamping mechanism is provided on the inner side of the protective shell 1, and the feeding rhythm is controlled by the position state of the clamping mechanism;

[0048] The clamping mechanism includes: a support plate 16, which is fixedly disposed on the inner surface of the protective shell 1, and a limiting hydraulic rod 17 is fixedly installed on the lower surface of the support plate 16 and the inner bottom surface of the protective shell 1. A sliding seat 18 is fixedly disposed on one end of the limiting hydraulic rod 17, and a sliding clamping plate 19 is installed on one end of the sliding seat 18.

[0049] Two limiting hydraulic rods 17 are arranged facing each other. A spring is connected between the sliding seat 18 and the clamping plate 19. The outer surfaces of the two sliding seats 18 facing each other are in contact with each other, and the outer surfaces of the two clamping plates 19 facing each other are in contact with each other.

[0050] After the hydraulic hose mounting plate 3 rotates into place, the lower limit hydraulic rod 17 starts to drive the sliding seat 18 and clamping plate 19 to move upward to support the hose extending from the hydraulic hose mounting plate 3. Then, the limit hydraulic rod 17 installed on the upper support plate 16 drives the sliding seat 18 and clamping plate 19 to move downward. The clamping plates 19 on the upper and lower sides fit together to press and lock the hose extending from the hydraulic hose mounting plate 3.

[0051] Example 3

[0052] This embodiment discloses, based on Embodiments 1 and 2, that: a feeding mechanism is provided at the lower end of the protective shell 1, which simultaneously performs the crimping and feeding of the joint by rotation;

[0053] The feeding mechanism includes: a side support plate 20, which is fixedly installed on the inner surface of the protective shell 1. A feeding motor 21 is fixedly installed on the outer surface of the side support plate 20, and a feeding tray 22 is fixedly connected to one end of the output shaft of the feeding motor 21. A magnetic mounting bracket 23 is fixedly installed on the side surface of the feeding tray 22. A push-out hydraulic rod 24 is fixedly installed on the upper side surface of the side support plate 20. A feeding hydraulic rod 25 is fixedly installed on the lower end face of the protective shell 1, and a feeding rod 26 is fixedly connected to one end of the feeding hydraulic rod 25. A feeding cylinder 27 is fixedly installed on the lower end face of the protective shell 1.

[0054] The magnetic mounting brackets 23 are evenly distributed on the outer surface of the feeding tray 22 facing the clamping plate 19. One end of the ejecting hydraulic rod 24 is set directly opposite the clamping plate 19. The lower end side surface of the feeding cylinder 27 is provided with a circular opening, and the upper end of the feeding cylinder 27 is designed as an opening. The feeding rod 26 is directly opposite the circular opening on the lower end side surface of the feeding cylinder 27, and the end of the feeding rod 26 facing the feeding cylinder 27 is designed as a frustum.

[0055] A third contact switch 30 is fixedly installed on the side surface of the support plate 16, a second contact switch 29 is fixedly installed on the outer surface of the limiting hydraulic rod 17, and a trigger plate 28 is fixedly installed on the outer surface of the upper limiting hydraulic rod 17 connected to the sliding seat 18, and the trigger plate 28 is located between the second contact switch 29 and the third contact switch 30.

[0056] During loading, the connectors to be installed are first placed inside the loading cylinder 27 in a predetermined direction. Then, the trigger plate 28 moves downward with the sliding seat 18, triggering the second contact switch 29. The second contact switch 29 sends an electrical signal to the ejection hydraulic rod 24 and the loading hydraulic rod 25. At this time, the ejection hydraulic rod 24 first moves to eject the connector attracted in the magnetic mounting bracket 23 and insert it into the hose held by the clamping plate 19. Then, the ejection hydraulic rod 24 retracts. At the same time, the loading hydraulic rod 25 starts, driving the loading rod 26 to extend into the lower end of the loading cylinder 27, ejecting the connector inside the lower end of the loading cylinder 27 and attracting it to the magnetic mounting bracket 23. Then, the loading hydraulic rod 25 drives the loading rod 26. During the retraction process, the feeding rod 26 is prevented from getting stuck with the unsupported connector in the feeding cylinder 27 by the inclined surface of the side surface. After the feeding rod 26 is retracted, the unsupported connector in the feeding cylinder 27 slides down to fill the gap. Then, when the limiting hydraulic rod 17 drives the sliding seat 18 and the clamping plate 19 to slide and reset, the trigger plate 28 above is driven to slide and reset and press the third contact switch 30. The third contact switch 30 sends an electrical signal to the feeding motor 21 on the surface of the side support plate 20. The feeding motor 21 starts and drives the feeding plate 22 to rotate, so that the magnetic mounting bracket 23 with the connector turns and pushes out the hydraulic rod 24, and the empty magnetic mounting bracket 23 turns to the lower end of the feeding cylinder 27, completing the automatic feeding.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
