However, precision equipment such as three-coordinate measuring machines are expensive and not suitable for industrial sites, making it difficult to accurately measure the length of the hose.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0031] Example 1

[0032] See also Figure 1-3 The present invention provides a technical solution: a system for accurately measuring the length of a hose based on morphological correction, comprising:

[0033] The morphology correction module includes a mounting frame 1 and several V-groove pulley groups arranged along the length of the mounting frame 1. The V-groove pulley group includes a fixed V-groove pulley 2 and a movable V-groove pulley 3. The fixed V-groove pulley 2 is rotatably mounted on the mounting frame 1, and the movable V-groove pulley 3 is rotatably mounted on a bracket 31. The bracket 31 is elastically connected to the mounting frame 1. The rubber hose 9 passes through the gap between the fixed V-groove pulley 2 and the movable V-groove pulley 3.

[0034] The length measuring module includes a base 4, a limit member 5, a first slide rail 6 and a grating ruler 8. The limit member 5 is fixedly installed at one end of the base 4. The position of the limit member 5 corresponds to the hose 9. The first slide rail 6 is arranged along the length direction of the mounting frame 1. A first measuring slider 61 is provided on the first slide rail 6. The end face position of the front side of the movement direction of the first measuring slider 61 corresponds to the end face of the limit member 5. A first photoelectric sensor 611 is provided on the first measuring slider 61. The height of the first photoelectric sensor 611 corresponds to the axis of the hose 9. The grating ruler 8 is arranged on one side of the first slide rail 6. The grating reading head 81 of the grating ruler 8 is connected to the first measuring slider 61.

[0035] A first flexible rubber layer is provided on the surface of the fixed V-groove pulley 2, and a second flexible rubber layer is provided on the surface of the movable V-groove pulley 3, to achieve flexible contact with the surface of the hose 9 and avoid damage to the surface of the hose 9 during the hose shape correction process.

[0036] Working principle: When a bent hose needs to be measured, the hose 9 is manually arranged along the length of the mounting frame 1 and sequentially passed through several V-groove pulley blocks. The elastic connection of the movable V-groove pulley 3 in the V-groove pulley block achieves elastic compression of the hose 9. The flexible compression force causes the hose 9 to stretch naturally, eliminating the bending caused by internal stress in the hose, thereby ensuring the accuracy of the length measurement of the hose 9.

[0037] When the end of the hose 9 rests against the end face of the limit member 5, the first measuring slider 61 on the first slide rail 6 in the length measuring module slides forward, and the grating reading head 81 moves synchronously along the scale grating of the grating ruler 8 to measure the length of the hose 9. The first photoelectric sensor 611 on the first measuring slider 61 scans the other end of the hose 9, triggering the reflection signal of the mounting bracket 1. At this time, the grating reading head 81 moving with the first measuring slider 61 generates a length measurement result based on the real-time collected displacement data, and alarms when the difference between the length measurement result and the standard length exceeds the set threshold.

[0038] Example 2

[0039] On the basis of the above embodiment, this embodiment further makes the following improved technical solutions: two parallel connecting rods 311 are provided on the back of the bracket 31, and the connecting rods 311 pass through the mounting frame 1 and the synchronization plate 11 and are connected to the nuts. A spring 312 is provided on the connecting rod 311, and one end of the spring 312 contacts the back of the bracket 31 and the other end contacts the mounting frame 1. The piston rod of the electric push rod 12 is connected to the synchronization plate 11.

[0040] When the piston rod of the electric push rod 12 drives the synchronous plate 11 to move upward as a whole, several movable V-groove pulleys 3 and their brackets 31 move upward, increasing the spacing between the fixed V-groove pulley 2 and the movable V-groove pulley 3 to adapt to hoses 9 of different diameters. At the same time, the elastic pressing force of the movable V-groove pulley 3 is increased, and the correction force for hoses 9 with larger diameters is greater, and the correction effect is better.

[0041] Symmetrically arranged guide rods 13 are provided on both sides of the synchronization plate 11 , and the synchronization plate 11 is slidably connected to the guide rods 13 , and the guide rods 13 are fixedly mounted on the mounting frame 1 , further ensuring the smooth lifting of the synchronization plate 11 .

[0042] Example 3

[0043] This embodiment further provides the following improved technical solutions based on the above embodiments: a screw drive mechanism 41 is provided at the end of the base 4 , and the base 4 is fixedly mounted on a nut lifting seat 411 of the screw drive mechanism 41 .

[0044] The screw drive mechanism 41 is used to adjust the overall height of the length measuring module. When the morphology correction module positions the hoses 9 of different diameters, the height of the first photoelectric sensor 611 and the height of the center of the limiter 5 are synchronously moved to align with the height of the axis of the hose 9 to ensure the accuracy of the length measurement.

[0045] Example 4

[0046] This embodiment further provides the following improved technical solution based on the above embodiment: a pressure sensor is provided on the limiting member 5 , and is used to trigger the start of the first measuring slider 61 .

[0047] When the hose 9 is fed into the shape correction module, the end of the hose 9 presses against the surface of the limiter 5 and is detected by the pressure sensor, and the first measuring slide 61 is promptly started to slide and measure.

[0048] A second photoelectric sensor 51 is located at the center of the stopper 5. This sensor is coaxial with the hose 9 and is used to detect whether the hose 9 is properly axially obstructed, meaning that the hose 9 is properly straightened and free of light-blocking bending deformation. This prevents length measurement when the hose 9 is not properly straightened.

[0049] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
