Description

Technical Field

[0001] This invention patent relates to the field of KV angle adjustment technology for hose assemblies, specifically to an auxiliary device for KV angle adjustment of hose assemblies. Background Technology

[0002] In assembling hose elbows, the terminology is defined as follows:

[0003] K-angle: refers to the angle between the elbow of the assembly and the natural bending direction of the hose;

[0004] V-angle: refers to the specified angle between two bends when both ends of the assembly are elbow joints;

[0005] Proximal end: With the hose assembly perpendicular to the viewer, the end closest to the viewer is the proximal end;

[0006] Distal end: With the hose assembly perpendicular to the viewer, the end furthest from the viewer is the distal end;

[0007] Install the hose elbow at the near end, straighten the hose assembly and look along the straight line. At the same time, keep the elbow vertically downward and consistent with the natural bending direction of the hose. Rotate the near end connector counterclockwise. The angle rotated at this time is the spatial angle K of the hose assembly. The tolerance of the spatial angle K is ±5°.

[0008] Straighten the hose assembly and look along the straight line. Place the farthest connector vertically and measure the angle between the nearest connector and the farthest vertically placed connector clockwise. This angle is the assembly angle of the hose assembly, considered as spatial angle V, with a tolerance of ±3°. If one connector is straight, there is no assembly angle, and the default is K=0°.

[0009] Publication (Announcement) No.: CN213422066U, discloses an assembly angle inspection tool for automotive hoses, which reduces manual inspection labor, improves inspection efficiency, increases inspection stability, and reduces usability. It also includes a base, support frame, rollers, connecting shaft, support member, inspection arm, connector, support shaft, and adjustment device. The bottom end of the support frame is installed on the left side of the top of the base. The rollers are rotatably installed on the top of the support frame via the connecting shaft, and multiple rollers are installed in cooperation. The left end of the support member is installed on the top right end of the support frame. The top end of the connector is installed on the left side of the bottom of the inspection arm. The bottom end of the connector is rotatably connected to the right end of the support member via the support member. The adjustment device is installed on the right side of the top of the base, and the output end of the adjustment device is connected to the inspection arm.

[0010] In this prior art, the angle of the hose bend is measured only by an angle gauge, which cannot measure the assembly space angle V between the near end and the far end. This means that the angle can only be measured at one end and cannot be used for measuring the space angle of the hose bend. Therefore, the prior art needs to be significantly structurally improved to adapt it to the use of measuring the space angle of the hose bend.

[0011] Publication (Announcement) No.: CN214213642U discloses an automotive hose connector assembly device capable of angle fine adjustment, including a device housing and a second threaded rod. An observation window is installed at the front end of the device housing. A first clamping block and a second clamping block are connected sequentially from left to right at the upper end of the automotive connecting hose. A first gear is provided on the outside of the first threaded rod. A first motor is installed at the lower end of the second gear. A first spring and a first guide rod are connected sequentially from the outside to the inside at the upper end of the second clamping block. A connecting plate is connected to the upper end of the first spring. A second spring and a second guide rod are connected sequentially from the outside to the inside at the upper end of the connecting plate.

[0012] In this prior art, the automotive hose connector is adjusted and assembled using an angle fine-tuning device to facilitate installation and achieve a standardized, sealed installation. However, this device only adjusts the installation method of the hose connector without considering the installation angle of the hose or the direction of wear and tear, thus failing to improve the scientific use of the hose and hose connector.

[0013] Therefore, an auxiliary device for adjusting the KV angle of the hose assembly is required.

[0014] In view of the problems existing in the prior art, this invention provides a KV angle adjustment auxiliary device for hose assembly, which aims to solve the technical problems mentioned above.

[0015] To achieve the above objectives, this invention patent provides the following technical solution: a hose assembly KV angle adjustment auxiliary device, comprising a support platform, a slide rail, a near-end platform one, and a far-end platform one. The support platform is provided with slide rails distributed at both ends along its width. Slide rail frame one and slide rail frame two are sequentially arranged on the slide rails along the length of the support platform. Slide rail frame one and slide rail frame two can be positioned and installed with the slide rails. The support platform located below slide rail frame one is designated as near-end platform one, and the support platform located below slide rail frame two is designated as far-end platform one. Far-end platform one is fixedly connected to the inner side of slide rail frame two. A fixed base one is snapped onto slide rail frame one. A sliding base one is provided on the side of fixed base one away from near-end platform one. A sliding rod one is provided inside the sliding base one. The sliding rod one slides inside the sliding base one, and its sliding distance is fixed by a limiting mechanism. A limit sleeve is provided at the bottom end of the sliding base 1 through the sliding rod 1. A pipe clamp 1 is provided inside the limit sleeve, and the pipe clamp 1 is fixedly installed to the inner top wall of the limit sleeve by at least two springs. A limit groove 1 is opened on the surface of the near end platform 1 below the pipe clamp 1. The limit groove 1 is coaxial with the pipe clamp. A connector end pipe clamp 2 is provided on the surface of the near end platform 1. The connector end pipe clamp 2 is coaxial with the limit groove. The surface of the far end platform 1 near the near end platform 1 is provided as a pipe clamp 3. The surface of the far end platform 1 away from the pipe clamp 3 is provided as a pipe clamp 4. The pipe clamp 3 and the pipe clamp 4 are coaxial. A slide rail 1 is symmetrically provided at the bottom of the side of the far end platform 1 near the pipe clamp 4. A slide rail 3 is slidably installed inside the slide rail 1. An angle ruler fixing plate is connected to the end face of the slide rail 3 away from the far end platform 1. A spatial angle ruler is provided in the middle of the angle ruler fixing plate.

[0016] Preferably, the limiting mechanism is a bolt, and a bolt is threaded on one side of the sliding base. The bolt abuts against the sliding rod, which is slidably mounted, so that it is positioned inside the sliding base.

[0017] Preferably, both the angle ruler fixing plate and the spatial angle ruler are made of transparent materials.

[0018] Preferably, slide rail bracket one and slide rail bracket two have the same structure, both including slider one, bracket, and positioning plate one. Slider one is installed inside the slide rail, and the top of slider one is fixedly connected to the bracket. Positioning plate one is installed on one side of the bottom of the bracket, and positioning plate one is fixedly installed to the slide rail by bolt two.

[0019] Preferably, the second and third pipe clamps at the connector end are coaxially arranged.

[0020] Preferably, a handle is provided at the top of the slide bar.

[0021] Preferably, the top surfaces of both the near-end platform 1 and the far-end platform 1 are on the same horizontal plane.

[0022] Preferably, the arc dimension of the first pipe clamp is greater than the arc dimension of the first limiting groove.

[0023] In summary, this invention provides an auxiliary device for adjusting the KV angle of a hose assembly. The beneficial effects of this invention are as follows: when the hose clamp one contacts the hose elbow at the near end, the slide rod one is pressed down further to further clamp and stabilize the hose elbow at the near end. The slide rod one is positioned and installed on the sliding base one by the limiting mechanism, thereby achieving vertical downward fixation of the hose elbow at the near end. The sliding rail frame one is positioned and installed with the slide rail, further improving the vertical downward fixation of the hose elbow at the near end. The hose connected near the hose elbow is clamped to the hose clamp two at the joint end along the natural bending direction, thereby fixing one side of the hose on the near end platform one.

[0024] The distal hose elbow is secured in clamp four by clamping it along the vertical direction of the hose bend. The hose near the distal hose elbow is secured in clamp three, thus fixing the distal hose elbow on the distal platform one. Then, slide slide rail three towards the distal hose elbow, so that the spatial angle ruler contacts the distal hose elbow. The downward vertical direction of the spatial angle ruler coincides with the downward vertical direction of the near hose elbow. Rotate the angle pointer on the spatial angle ruler to coincide with the axis of the distal hose elbow. At this time, the spatial rotation angle pointed to by the angle pointer is the spatial angle V between the distal hose elbow and the near hose elbow.

[0025] The measuring assembly angle structure adopted in this invention patent can measure the installation angle of the near and far ends of the elbows using hoses of different lengths. It is flexible in use and practical and easy to operate during the measurement process, suitable for different technical personnel. The error meets the angle adjustment standard. This angle adjustment device can be mass-produced, and the installation measurement of hoses of different lengths and elbows at both ends can be mass-produced, which improves the production efficiency and quality of hose assemblies.

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings.

[0032] like Figures 1 to 4 As shown:

[0033] This invention patent is an auxiliary device for adjusting the KV angle of a hose assembly, including a support platform 1, a slide rail 2, a proximal platform 3, and a distal platform 4. The support platform 1 has slide rails 2 distributed at both ends along its width. Slide rail frames 5 and 6 are sequentially arranged on the slide rails 2 along the length of the support platform 1. Slide rail frames 5 and 6 can be positioned and installed with the slide rails 2. The proximal platform 3 is located below the slide rail frame 5, and the distal platform 4 is located below the slide rail frame 6. The distal platform 4 is fixedly connected to the inner side of the slide rail frame 6. A fixed base 7 is snapped onto the slide rail frame 5. A sliding base 11 is located on the side of the fixed base 7 away from the proximal platform 3. A sliding rod 12 is installed inside the sliding base 11. The sliding rod 12 slides inside the sliding base 11, and its sliding distance is fixed by a limiting mechanism 13. A limit device is provided at the bottom end of the sliding base 11 through the sliding rod 12. A limiting sleeve 14 has a pipe clamp 15 inside, which is fixedly installed to the inner top wall of the limiting sleeve 14 by at least two springs 16. A limiting groove 17 is formed on the surface of the proximal platform 3 below the pipe clamp 15, and the limiting groove 17 is coaxially arranged with the pipe clamp 15. A connector end pipe clamp 21 is provided on the surface of the proximal platform 3, and the connector end pipe clamp 21 is coaxially arranged with the limiting groove 17. The distal platform 4 is close to the proximal platform 1. One side surface of 3 is set as pipe clamp 3 22, and the side surface of the far end platform 4 away from pipe clamp 3 22 is set with pipe clamp 4 23. Pipe clamp 3 22 and pipe clamp 4 23 are set coaxially. The bottom of the side of the far end platform 4 near pipe clamp 4 23 is symmetrically set with slide rail 1 24. Slide rail 3 25 is slidably installed inside slide rail 1 24. Angle ruler fixing plate 26 is connected to the end face of slide rail 3 25 away from far end platform 4. Spatial angle ruler 27 is set in the middle of angle ruler fixing plate 26.

[0034] To address the technical problems existing in the prior art, the technical structure adopted in this invention patent is as follows: During the KV angle adjustment operation, the hose bend is placed vertically upward or downward during the angle test. In this embodiment, the hose bend is placed vertically downward for testing. The connection between the hose bend and the hose at the near end is limited and placed on the limiting groove 17, keeping the hose bend vertically downward. The sliding rail bracket 5 is moved above the hose bend at the near end, and the sliding rod 12 is pressed down inside the sliding base 11, causing the limiting sleeve 14 and the hose clamp 15 to be pressed down together, so that the hose clamp 15 mates with the limiting groove 17. The hose bend at the proximal end is clamped. When the hose clamp 15 contacts the proximal hose bend, the slide bar 12 is pressed down further to further clamp and stabilize the proximal hose bend. The slide bar 12 is positioned and installed on the sliding base 11 by the limiting mechanism 13, so as to fix the proximal hose bend vertically downward. The sliding slide rail frame 5 is positioned and installed with the slide rail 2, which further improves the vertical fixation of the proximal hose bend. The hose connected near the proximal hose bend is clamped to the connector end hose clamp 21 along the natural bending direction, so as to fix the proximal side of the hose on the proximal platform 3.

[0035] Depending on the length of the hose, the distance between the distal platform 4 and the proximal platform 3 is adjusted by sliding to accommodate the assembly angle detection of different hose lengths. In this embodiment, it is crucial to ensure the natural curvature of the hose to guarantee its quality. The area on the distal platform 4 and the area between the distal platform 4 and the proximal platform 3 are used to place the hose. At this time, slide out the slide rail 3 25, pull out the angle ruler fixing plate 26 and the spatial angle ruler 27, providing space for the distal hose elbow to be snapped into place. The distal hose elbow is snapped into place by the hose clamp along the vertical direction of the hose's curvature. Inside the fourth 23, the hose clamp near the far end of the hose bend is inserted into the hose clamp three 22 to complete the fixed installation of the far end hose bend on the far end platform one 4. Then, slide the slide rail three 25 towards the far end hose bend so that the space angle ruler 27 contacts the far end hose bend. The downward vertical direction of the space angle ruler 27 coincides with the downward vertical direction of the near end hose bend. Rotate the angle pointer on the space angle ruler 27 to coincide with the axis of the far end hose bend. At this time, the spatial rotation angle pointed to by the angle pointer is: the spatial angle V between the far end hose bend and the near end hose bend.

[0036] The measuring assembly angle structure adopted in this invention patent can measure the installation angle of the near and far ends of the elbows using hoses of different lengths. It is flexible in use and practical and easy to operate during the measurement process, suitable for different technical personnel. The error meets the angle adjustment standard. This angle adjustment device can be mass-produced, and the installation measurement of hoses of different lengths and elbows at both ends can be mass-produced, which improves the production efficiency and quality of hose assemblies.

[0037] In at least one embodiment, in order to achieve a stable clamping structure by having the pipe clamp 15 and the limiting groove 17 cooperate to hold the proximal end of the hose elbow, the following structure is adopted: the limiting mechanism 13 is set as a bolt 31, and a bolt 31 is threaded on one side of the sliding base 11. The bolt 31 abuts against the sliding rod 12, positioning it inside the sliding base 11, so as to achieve a stable clamping of the proximal end of the hose elbow by the pipe clamp 15. At the same time, the spring 16 is set to protect the proximal end of the hose elbow during the clamping and fixing process of the pipe clamp 15, avoiding clamping marks and damage to the proximal end of the hose elbow.

[0038] In at least one embodiment, in order to facilitate and expedite the measurement of the spatial angle V between the distal and proximal hose bends, the angle ruler fixing plate 26 and the spatial angle ruler 27 are both made of transparent materials, preferably any one of AS, PC, PMMA, ABS, or PET, to avoid scratches that could affect the accuracy of the angle measurement.

[0039] In at least one embodiment, in order to further fix the proximal hose bend after it has been vertically fixed downwards, the following structure is adopted: the slide rail frame 5 and the slide rail frame 6 have the same structure, both including a slider 32, a bracket 33, and a positioning plate 34. The slide rail 2 is provided with a slider 32 inside, the top of the slider 32 is fixedly connected to the bracket 33, and the bottom side of the bracket 33 is provided with a positioning plate 34. The positioning plate 34 is fixedly installed to the slide rail 2 by bolts 2.

[0040] Specifically: After the near-end hose elbow is fixed vertically downward in the limiting groove 17, the sliding slider 32 slides with the slide rail 2, so that the bracket 33 moves above the near-end hose elbow. After the pipe clamp 15 and the limiting groove 17 cooperate to clamp the near-end hose elbow, the positioning plate 34 is fixed to the slide rail 2 by bolt 2, and the pipe clamp 15 is further positioned and installed to clamp and fix the near-end hose elbow.

[0041] In at least one embodiment, in order to achieve the clamping and installation of the proximal end of the hose elbow along the natural bending direction of the hose between the hose clamp 15 and the limiting groove 17, and the connection of the connector end hose clamp 21 with the hose, so as to ensure the quality of the hose in its natural state, the connector end hose clamp 21 and hose clamp 32 are coaxially arranged.

[0042] In at least one embodiment, in order to achieve rapid and convenient downward sliding of the slide bar 12, a handle 35 is provided at the top of the slide bar 12.

[0043] In at least one embodiment, in order to measure the spatial assembly angle of the hose in a naturally bent state, a structure is adopted in which the top surfaces of the near-end platform-3 and the far-end platform-4 are on the same horizontal plane.

[0044] In at least one embodiment, in order to achieve a stable clamping of the proximal hose elbow, the arc dimension of the hose clamp-15 is larger than the arc dimension of the limiting groove-17, so as to achieve a clamping and installation of the proximal hose elbow in a way that surrounds it, further increasing the clamping and fixing of the proximal hose elbow and improving the accuracy of spatial assembly angle measurement.

[0045] The embodiments described in this patent are for illustrative purposes only and do not constitute a limitation on the scope of the claims. Other substantially equivalent alternatives that can be conceived by those skilled in the art are all within the scope of protection of this patent.
