Description

Technical Field

[0001] This invention belongs to the technical field of plastic pipe fitting press fitting, and more specifically, relates to a hose press fitting device. Background Technology

[0002] In hose production, two shorter hoses are typically joined together to form the desired length of the finished product. Because different branch pipes are attached to the hose, there are few clamping points during assembly, and it is difficult to determine a fixed clamping position. Therefore, in existing technologies, hose assembly cannot be automated and must be done manually.

[0003] The existing technology has the following drawbacks: Although the method of manually assembling the hose can solve the problem that automated equipment has difficulty in determining a fixed clamping position, the method of manually assembling the hose is inefficient and the labor intensity of the workers is high. Summary of the Invention

[0004] The purpose of this invention is to provide a hose pressing device, which aims to solve the problems of low efficiency and high labor intensity of workers in the existing manual hose assembly method.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a hose pressing device, comprising: support; Two end press-fit assemblies are mounted on the bracket; and At least two hose clamps are provided, each hose clamp being disposed between the two end pressing assemblies and slidably connected to the bracket along the spacing direction of the two end pressing assemblies; each hose clamp has a hose fixing and holding groove and forms a clearance groove communicating with the clamping groove, the clearance groove being used for a branch pipe to pass through; The end-press assembly is used to apply pressure to the two clamped tubing, causing the tubing to move relative to each other and form an insertion.

[0006] In one possible implementation, the hose clamp includes: The sliding seat is slidably connected to the bracket; and At least one clamping assembly is fixedly connected to the sliding seat; each clamping assembly includes a fixed seat and a lifting seat; the fixed seat is fixedly connected to the sliding seat, and the upper end face of the fixed seat is provided with a lower half-shaped through hole and a lower half-side hole communicating with the lower half-shaped through hole; the lower end face of the lifting seat is provided with an upper half-shaped through hole and an upper half-side hole communicating with the upper half-shaped through hole; the lifting seat in each clamping assembly forms the clamping groove and the clearance groove after engaging with the fixed seat.

[0007] In one possible implementation, the clamping component further includes: A support member is fixedly connected to the upper surface of the sliding seat; the lifting seat is slidably connected to the side of the support member; the lifting seat can be raised and lowered vertically; and A drive mechanism is disposed on the support member and connected to the lifting seat; the drive mechanism is used to drive the lifting seat to move up and down so as to clamp and fix the hose in the clamping groove.

[0008] In one possible implementation, the drive mechanism includes: The sleeve is fixedly connected to the support member; A sliding rod is slidably inserted into the sleeve; the bottom of the sliding rod is fixedly connected to the lifting seat. A handle, hinged to the support member; the hinge point of the handle is located above the slide bar; and The connector has its bottom end hinged to the top of the slide bar and its top end hinged to the handle.

[0009] In one possible implementation, the handle includes: The first part is hinged at its top to the support member; the top of the connecting member is hinged to the bottom of the first part; when the lifting seat contacts the fixed seat, the first part, the connecting member, and the sliding rod are collinear; and The second part is fixedly connected to the first part; there is a certain angle between the second part and the first part.

[0010] In one possible implementation, two connectors are provided; the two connectors are respectively provided on both sides of the handle and are symmetrically arranged about the handle.

[0011] In one possible implementation, two parallel guide rails are fixedly connected to the bracket, and two sliders are fixedly connected to the sliding seat, with the two sliders slidingly engaging with the two guide rails respectively.

[0012] In one possible implementation, the end-press assembly includes: The driving component is fixedly connected to the bracket; and The pressing component is slidably connected to the bracket, and the sliding path of the pressing component is collinear with the centerline of the hose; the driving component is connected to the pressing component and drives the pressing component to slide, so as to apply pressure to the hose held by the hose clamp and insert the hose together.

[0013] In one possible implementation, the pressing component has a fixing groove, and when the hose is pressed, the end of the hose is fixed in the fixing groove.

[0014] In one possible implementation, the press-fit component is further provided with a negative pressure hole, which is located around the fixing groove. The end of the hose is inserted into the fixing groove and then blocks the negative pressure hole. The negative pressure hole is used to connect to a negative pressure pump so that negative pressure is generated inside the negative pressure hole.

[0015] The beneficial effects of the hose pressing device provided by this invention are as follows: Compared with the prior art, the hose pressing device of this invention provides stable support for the overall structure through a bracket, ensuring the stable operation of subsequent components. The bracket provides a reliable installation foundation for the device, avoiding operational deviations caused by structural instability during the pressing process, and creating the prerequisite for accurate hose pressing.

[0016] Two end-pressing components are mounted on the support, enabling pressure to be applied to the hose held by the hose clamp. This pressure application method replaces manual force in pushing the hose to complete the insertion operation, eliminating the need for workers to manually apply pressure and significantly reducing physical exertion. Simultaneously, the pressure application process of the end-pressing components is more stable and uniform, ensuring consistent force during hose insertion and reducing the likelihood of incomplete or damaged hose insertion due to uneven manual force, thus improving the reliability of hose insertion.

[0017] At least two hose clamps are slidably connected to the support and positioned between the two end pressing assemblies, with their sliding path collinear with the centerline of the hose. This structural design allows the hose clamps to be flexibly adjusted along the hose's centerline according to the actual length of the hose and insertion requirements. Regardless of the position of the branch pipe on the hose, a suitable clamping point can be found by adjusting the position of the hose clamps, solving the problem of difficulty in determining the clamping position due to the presence of the branch pipe. This eliminates the need for operators to spend time searching for and adjusting the clamping position, significantly improving operational convenience.

[0018] The hose clamp includes a fixed base and a height-adjustable lifting base. Both the top side of the fixed base and the bottom side of the lifting base are equipped with clamping grooves and clearance grooves. When fixing the hose, the lifting base is positioned directly above the fixed base, stably clamping and securing the hose within the clamping grooves. This clamping method is more secure than manual handling, preventing hose displacement during pressing and ensuring accuracy. Simultaneously, the clearance grooves effectively avoid branch pipes on the hose, preventing damage during clamping, protecting the hose's integrity, and reducing scrap rates due to branch pipe damage.

[0019] The end-press assembly applies pressure to the hoses and inserts them together. The entire insertion process eliminates the need for manual connection and pushing, achieving mechanized operation of the hose assembly process. Compared to manual assembly, mechanized operation is faster, enabling the assembly of more hoses in a shorter time, significantly improving hose assembly efficiency. Simultaneously, workers only need to perform simple loading and unloading operations, eliminating the need for prolonged, repetitive, high-intensity assembly work, effectively reducing labor intensity and improving the working environment.

[0030] Reference Figures 1 to 5 The hose pressing device provided by the present invention will now be described. The hose pressing device includes a support 1, two end pressing assemblies 2, and at least two hose clamps 3.

[0031] The end pressing assembly 2 is mounted on the bracket 1. Each hose clamp 3 is mounted between two end pressing assemblies 2 and is slidably connected to the bracket 1 along the interval direction of the two end pressing assemblies 2; each hose clamp 3 has a hose fixing and holding groove 323 and forms a clearance groove 324 that communicates with the holding groove 323, the clearance groove 324 is used for the branch pipe to pass through; The end pressing assembly 2 is used to apply pressure to the two clamped tubing, causing the tubing to move relative to each other and form an insert.

[0032] The beneficial effects of the hose pressing device provided by this invention are as follows: Compared with the prior art, the hose pressing device of this invention provides stable support for the overall structure through the bracket 1, ensuring the stable operation of subsequent components. The bracket 1 provides a reliable installation foundation for the device, avoiding operational deviations caused by structural instability during the pressing process, and creating the preconditions for accurate hose pressing.

[0033] Two end-pressing components 2 are mounted on the bracket 1, which can apply pressure to the hose held by the hose clamp 3. This pressure application method can replace the manual force of pushing the hose to complete the insertion operation, eliminating the need for workers to manually apply pressure and greatly reducing the physical exertion of workers. At the same time, the pressure application process of the end-pressing components 2 is more stable and uniform, ensuring that the force is consistent during hose insertion, reducing the possibility of incomplete hose insertion or damage due to uneven manual operation, and improving the reliability of hose insertion.

[0034] At least two hose clamps 3 are slidably connected to the bracket 1 and positioned between the two end pressing components 2, with their sliding path collinear with the centerline of the hose. This structural design allows the hose clamps 3 to be flexibly adjusted along the centerline of the hose according to its actual length and insertion requirements. Regardless of the position of the branch pipe on the hose, a suitable clamping point can be found by adjusting the position of the hose clamps 3, solving the problem of difficulty in determining the clamping position due to the presence of the branch pipe. This eliminates the need for operators to spend time searching for and adjusting the clamping position, significantly improving operational convenience.

[0035] The hose clamp 3 includes a fixed base 321 and a liftable lifting base 322. The top side of the fixed base 321 and the bottom side of the lifting base 322 are both provided with clamping grooves 323 and clearance grooves 324. When fixing the hose, the lifting base 322 is located directly above the fixed base 321, stably clamping and fixing the hose in the clamping groove 323. This clamping method is more secure than manual handling, preventing hose displacement during pressing and ensuring pressing accuracy. Simultaneously, the clearance groove 324 effectively avoids branch pipes on the hose, preventing damage to the branch pipes during clamping, protecting the integrity of the hose, and reducing the scrap rate due to branch pipe damage.

[0036] The end-pressing assembly 2 applies pressure to the hoses and inserts them together. The entire insertion process requires no manual connection or pushing, achieving mechanized operation of the hose assembly process. Compared to manual assembly, mechanized operation is faster, enabling the assembly of more hoses in a shorter time, significantly improving hose assembly efficiency. Simultaneously, workers only need to perform simple loading and unloading operations, eliminating the need for prolonged, repetitive, high-intensity assembly work, effectively reducing the labor intensity of workers and improving the working environment. In one possible implementation, the hose clamp 3 includes a sliding seat 31 and at least one clamping assembly 32.

[0037] The sliding seat 31 is slidably connected to the bracket 1. The clamping assembly 32 is fixedly connected to the sliding seat 31; each clamping assembly 32 includes a fixed seat 321 and a lifting seat 322; the fixed seat 321 is fixedly connected to the sliding seat 31, and the upper end face of the fixed seat 321 is provided with a lower half-shaped through hole and a lower half-side hole communicating with the lower half-shaped through hole; the lower end face of the lifting seat 322 is provided with an upper half-shaped through hole and an upper half-side hole communicating with the upper half-shaped through hole; after the lifting seat 322 in each clamping assembly 32 mates with the fixed seat 321, it forms a clamping groove 323 and a clearance groove 324.

[0038] The sliding base 31 provides a stable mounting platform for the clamping assembly 32, allowing the clamping assembly 32 to slide synchronously along the bracket 1 with the sliding base 31, ensuring that the clamping assembly 32 remains stable during position adjustments. Simultaneously, the number of at least one clamping assembly 32 can be flexibly configured according to the length of the hose and clamping requirements. When the hose is long, increasing the number of clamping assemblies 32 enhances the clamping stability, preventing the hose from sagging or shifting in the middle during press-fitting due to excessive length. This structural design further optimizes the flexibility and applicability of the hose clamp 3, better adapting to the clamping requirements of different hose specifications and providing more reliable clamping assurance for subsequent precise press-fitting.

[0039] In one possible implementation, the clamping assembly 32 also includes a support 325 and a drive mechanism.

[0040] The support member 325 is fixedly connected to the upper surface of the sliding seat 31; the lifting seat 322 is slidably connected to the side of the support member 325; the lifting seat 322 can be raised and lowered in the vertical direction. The drive mechanism is set on the support member 325 and connected to the lifting seat 322; the drive mechanism is used to drive the lifting seat 322 to rise and fall, so as to clamp and fix the hose in the clamping groove 323.

[0041] The support component 325 provides a stable sliding track for the lifting seat 322, ensuring that the lifting seat 322 remains vertical during lifting and lowering, preventing deviation of the lifting seat 322 from causing misalignment in the hose clamping position, and laying the foundation for precise hose clamping. Operators do not need to manually lift or press the lifting seat 322 to adjust its position; the lifting seat 322 can be raised and lowered simply through the drive mechanism. This driving method changes the traditional manual force application mode. With the mechanical transmission or assistance of the drive mechanism, the force required for clamping the hose is significantly reduced, eliminating the need for expending considerable physical effort to control the movement of the lifting seat 322, thus significantly reducing physical exertion during operation.

[0042] Meanwhile, the process of driving the lifting seat 322 by the drive mechanism is more stable and controllable, which can avoid the lifting seat 322 from suddenly jamming or shaking due to uneven manual force application, and reduce accidental collision or squeezing damage to the hose. This not only protects the integrity of the hose, but also makes the clamping operation easier and smoother, further improving the convenience and reliability of the overall operation.

[0043] In one possible implementation, the drive mechanism includes a sleeve 326, a slide bar 327, a handle 329, and a connector 328.

[0044] Sleeve 326 is fixedly connected to support member 325. Slide rod 327 is slidably inserted into sleeve 326; the bottom of slide rod 327 is fixedly connected to lifting seat 322. Handle 329 is hinged to support member 325; the hinge point of handle 329 is located above slide rod 327. The bottom end of connector 328 is hinged to the top of slide rod 327, and the top end is hinged to handle 329.

[0045] The drive mechanism consists of a sleeve 326 fixed to the support member 325, a slide rod 327 slidably inserted into the sleeve 326 and connected to the bottom of the lifting seat 322, a handle 329 hinged to the support member 325, and a connector 328 hinged at both ends to the top of the slide rod 327 and the handle 329 respectively. The sleeve 326 provides precise sliding guidance for the slide rod 327, ensuring that the slide rod 327 remains vertical when driving the lifting seat 322 to rise and fall, and preventing the lifting seat 322 from tilting. The handle 329, connector 328, and slide rod 327 form a linkage structure. The operator only needs to turn the handle 329 to drive the slide rod 327 to slide along the sleeve 326 through the connector 328, thereby controlling the rise and fall of the lifting seat 322. The operation is simple and convenient, and no additional tools are required. Compared to purely mechanical automatic drive, this manual drive method allows operators to more intuitively perceive the clamping force of the lifting seat 322. It can be flexibly adjusted according to the softness or hardness of the hose material, preventing damage to the hose due to excessive clamping force or loosening of the hose due to insufficient force. While ensuring ease of operation, it improves the controllability of clamping operation.

[0046] In one possible implementation, the handle 329 includes a first part 329a and a second part 329b.

[0047] The top of the first part 329a is hinged to the support member 325; the top of the connector 328 is hinged to the bottom of the first part 329a; when the lifting seat 322 contacts the fixed seat 321, the first part 329a, the connector 328, and the slide rod 327 are collinear. The second part 329b is fixedly connected to the first part 329a; there is a certain angle between the second part 329b and the first part 329a.

[0048] When the lifting seat 322 contacts the fixed seat 321 to clamp the hose, the collinear structure of the first part 329a, the connector 328, and the slide rod 327 forms a dead point position. At this time, without external force acting on the handle 329, the lifting seat 322 can maintain a stable clamping state and will not loosen due to the reaction force of the hose or slight vibration of the device, significantly improving the stability of hose clamping and avoiding hose displacement during pressing, which affects the insertion accuracy. The second part 329b is designed at a certain angle to the first part 329a, increasing the lever arm of the operator operating the handle 329. According to the lever principle, the operator only needs to apply a small force to drive the lifting seat 322 to complete the clamping action, further reducing the operating force, making the operation more effortless, and improving the overall comfort and efficiency of the operation.

[0049] In one possible implementation, there are two connectors 328; the two connectors 328 are respectively disposed on both sides of the handle 329 and are symmetrically arranged about the handle 329.

[0050] Two symmetrically arranged connectors 328 evenly transmit force from both sides of the handle 329 to the slide bar 327, preventing uneven force distribution on the slide bar 327 due to force transmission from a single connector 328, thus avoiding tilting or jamming of the slide bar 327. This ensures that the slide bar 327 always slides smoothly along the sleeve 326, thereby guaranteeing the stable lifting and lowering of the lifting seat 322. Simultaneously, the symmetrical connector structure ensures balanced force distribution on both sides of the handle 329 during rotation, preventing deformation or damage due to excessive force on one side, and extending the service life of the handle 329 and connectors 328. This structural design further optimizes the force stability of the drive mechanism, improves the smoothness and reliability of the entire clamping assembly 32, and provides stronger structural support for stable hose clamping.

[0051] In one possible implementation, two parallel guide rails 11 are fixedly connected to the bracket 1, and two sliders are fixedly connected to the sliding seat 31, with the two sliders slidingly engaging with the two guide rails 11 respectively.

[0052] Two parallel guide rails 11 provide precise guidance for the slider, ensuring that the sliding seat 31 maintains a straight line motion when sliding along the guide rails 11. This prevents the sliding seat 31 from shifting or wobbling during position adjustment, ensuring that the hose clamp 3 can be accurately moved to the required clamping position. The two sliders and two guide rails 11 correspond one-to-one, increasing the contact area between the sliding seat 31 and the bracket 1, making the force on the sliding seat 31 more even during sliding, reducing wear between the sliding seat 31 and the guide rails 11, and extending the service life of the guide rails 11 and the sliders. At the same time, this sliding fit structure has low sliding resistance, making it easier for operators to push the sliding seat 31 to adjust its position, enabling quick adjustment of the hose clamp 3, improving operational efficiency, and laying the foundation for subsequent precise hose alignment and pressing.

[0053] In one possible implementation, the end press-fit assembly 2 includes a drive member 21 and a press-fit member 22.

[0054] The drive component 21 is fixedly connected to the bracket 1. The pressing component 22 is slidably connected to the bracket 1, and the sliding path of the pressing component 22 is collinear with the center line of the hose. The drive component 21 is connected to the pressing component 22 and drives the pressing component 22 to slide, so as to apply pressure to the hose held by the hose clamp 3 and insert the hose together.

[0055] The drive unit 21 provides a stable power source for the pressing component 22, replacing manual operation of pushing the pressing component 22 to apply pressure. This makes the force applied during the pressing process more stable and uniform, and the pressure is controllable. It can precisely adjust the applied pressure according to the hose insertion requirements, avoiding situations where the hose is not inserted properly or is damaged due to uneven manual operation. The sliding path of the pressing component 22 is collinear with the centerline of the hose, ensuring that the pressure applied by the pressing component 22 to the hose is always along the centerline of the hose. This ensures that the force direction on the hose is accurate during insertion, preventing problems such as hose bending or misalignment due to pressure deviation, significantly improving the accuracy and reliability of hose insertion. This mechanized pressing method greatly improves the efficiency of hose insertion while further reducing the labor intensity of workers.

[0056] In a preferred embodiment, the driving component 21 is a cylinder. The cylinder body is fixedly connected to the bracket 1 to ensure that the cylinder remains stable during operation and does not shift or shake. The piston rod end of the cylinder is fixedly connected to the pressing component 22. When compressed air is introduced into the cylinder, the compressed air will push the piston rod to perform linear reciprocating motion. When the piston rod moves, it will directly drive the connected pressing component 22, causing the pressing component 22 to move along the sliding path of the bracket 1, thereby applying pressure to the hose held by the hose clamp 3 to complete the hose insertion operation. By controlling the on / off state and pressure of the compressed air, the movement speed and thrust of the piston rod can be flexibly adjusted to adapt to the pressing requirements of hoses of different specifications, ensuring the stability and reliability of the pressing process.

[0057] In a preferred embodiment, the drive component 21 is an electric telescopic rod. The fixed end of the electric telescopic rod is firmly connected to the bracket 1, providing a stable installation base for the electric telescopic rod and preventing it from shifting during extension and retraction. The telescopic end of the electric telescopic rod is connected to the pressing component 22. When the electric telescopic rod is powered on, its internal motor drives the transmission mechanism to operate, converting the rotational motion of the motor into linear motion of the telescopic end. The linear motion of the telescopic end is directly transmitted to the pressing component 22, driving the pressing component 22 to slide along a preset sliding path, thereby achieving pressure application and insertion of the hose. By controlling the power supply, current direction, and working time of the electric telescopic rod, the extension length, movement speed, and thrust of the telescopic end can be precisely controlled, meeting the precise pressure and displacement requirements during the pressing of different hoses. Furthermore, the electric telescopic rod does not require an additional air or hydraulic source, making its application more flexible.

[0058] In a preferred embodiment, the drive component 21 is a motor lead screw structure. This structure includes a motor, a lead screw, and a lead screw nut. The motor body is fixed to the bracket 1. One end of the lead screw is fixedly connected to the output shaft of the motor via a coupling, ensuring that the motor can drive the lead screw to rotate synchronously when rotating. The lead screw nut is threaded into the lead screw and is fixedly connected to the pressing component 22. Simultaneously, the pressing component 22 is slidably connected to the bracket 1, restricting the rotational movement of the lead screw nut with the lead screw. When the motor starts, the motor output shaft drives the lead screw to rotate. Due to the restriction of the sliding connection of the pressing component 22, the lead screw nut cannot rotate with the lead screw and can only move linearly along the axis of the lead screw. The linear movement of the lead screw nut causes the pressing component 22 to slide along the bracket 1, thereby applying pressure to the hose to complete the insertion. By controlling the forward and reverse rotation of the motor, the direction of movement of the pressing component 22 can be changed, and by controlling the motor speed, the speed of movement of the pressing component 22 can be adjusted. This structure enables precise control of the displacement and speed of the pressing component 22, making it suitable for hose assembly scenarios with high pressing accuracy requirements.

[0059] In one possible implementation, the press-fitting component 22 has a fixing groove 221, and the end of the hose is fixed in the fixing groove 221 when the hose is press-fitted.

[0060] The fixing groove 221 positions and fixes the end of the hose, preventing it from sliding or shifting on the pressing component 22 during the pressing process. This ensures that the pressure applied by the pressing component 22 is accurately transmitted to the hose end, allowing the hose to be stably inserted in the predetermined direction. Simultaneously, the fixing groove 221 maintains a relatively fixed position between the hose end and the pressing component 22. During the sliding of the pressing component 22, the hose end will not deviate from the pressing path due to inertia or external forces, further guaranteeing the coaxiality and accuracy of the hose insertion. This structural design is simple and effective, achieving stable positioning of the hose end without the need for additional complex positioning mechanisms, thus improving the practicality of the pressing component 22 and the stability of the pressing process.

[0061] In one possible implementation, the press-fit component 22 is also provided with a negative pressure hole 222, which is located around the fixing groove 221. The end of the hose is inserted into the fixing groove 221 and then the negative pressure hole 222 is blocked. The negative pressure hole 222 is used to connect to a negative pressure pump so that negative pressure is generated inside the negative pressure hole 222.

[0062] When the diameter of the hose end is smaller than the inner diameter of the fixing groove 221, the mechanical limiting of the fixing groove 221 alone cannot achieve stable fixing of the hose end. At this time, the negative pressure hole 222 can be connected to the negative pressure pump to form a negative pressure adsorption structure. This structure breaks through the strict limitation of traditional mechanical fixing on size matching. Without replacing the press fitting 22 adapted to small diameter hoses, it can fix hose ends of different diameters through negative pressure, greatly improving the adaptability of the press fitting 22 to hoses of different specifications.

[0063] After the end of the hose is inserted into the fixing groove 221, the negative pressure hole 222 is sealed. The operation of the negative pressure pump creates negative pressure inside the negative pressure hole 222. The suction force generated by the negative pressure can firmly adhere the end of the hose to the fixing groove 221. Even if there is a gap between the end of the hose and the fixing groove 221, the negative pressure force can eliminate the loosening problem caused by the gap. This fixing method avoids the hose shifting or falling off during the pressing process due to the small diameter of the hose end, ensuring that the hose is always in the preset pressing position during pressing, providing a stable positioning guarantee for accurate insertion.

[0064] Meanwhile, the negative pressure fixing method is convenient to operate. Simply controlling the start and stop of the negative pressure pump is enough to fix and release the hose end, eliminating the need for manual adjustment of the mechanical structure or replacement of parts, thus reducing operation steps and adjustment time. Furthermore, the force exerted by the negative pressure adsorption on the hose end is evenly distributed on the contact surface, preventing localized compression damage to the hose end caused by mechanical clamping. While ensuring a secure fixation, it effectively protects the structural integrity of the hose end, reducing the risk of damage due to improper fixing methods.

[0065] The beneficial effects of the hose pressing device provided by this invention are as follows: Through the coordinated cooperation of the support 1, the end pressing components 2, and the hose clamps 3, a mechanized hose assembly system is constructed, effectively solving the problems of low efficiency and high labor intensity in traditional manual assembly. The support 1 provides stable support for the overall structure, ensuring that no displacement or shaking occurs during the operation of each component, laying the foundation for subsequent precise operation; the two end pressing components 2 replace the manual pushing action of the hose, and realize the automatic insertion of the hose through stable pressure, avoiding incomplete insertion or hose damage caused by uneven manual operation force, significantly improving assembly reliability. At least two hose clamps 3 slidably connected to the support 1 have a sliding path collinear with the centerline of the hose, and can flexibly adjust the clamping point according to the hose length and branch pipe position. Combined with the clamping grooves 323 and avoidance grooves 324 on the fixed seat 321 and the lifting seat 322, they can firmly clamp the hose and avoid the branch pipe to prevent damage, solving the problem of difficulty in determining the clamping position due to the presence of the branch pipe. There is no need for operators to manually find and adjust the clamping position, greatly reducing the difficulty of operation.

[0066] Based on this, the device further enhances its practicality and stability through multi-structural optimization. The combination of the sliding seat 31 and the clamping assembly 32 in the hose clamp 3 allows for flexible configuration of the number of clamping assemblies 32 according to the hose specifications. Combined with the guide rail 11 on the bracket 1 and the slider of the sliding seat 31, this ensures precise and stable sliding of the clamp. The drive mechanism, through the linkage of the sleeve 326, slide rod 327, handle 329, and connector 328, utilizes the lever principle to reduce the force applied by the operator and forms a dead point position to ensure clamping stability. In the end-pressing assembly 2, the cooperation between the drive component 21 and the pressing component 22 achieves mechanization and precision in the pressing action. The fixing groove 221 of the pressing component 22 initially positions the hose end, while the negative pressure hole 222 solves the problem of fixing small-diameter hoses through negative pressure adsorption, preventing hose displacement or detachment. The overall solution transforms hose assembly from manual to mechanized, significantly improving assembly efficiency and reducing the labor intensity of workers. At the same time, through multi-dimensional structural design, it adapts to hoses of different specifications, protects the integrity of the hoses, reduces the scrap rate, and provides a reliable guarantee for the batch and high-quality assembly of hoses.
