Abstract
Description
Technical Field
[0001] This invention relates to the field of double-pipe clamp manufacturing technology, and in particular to a double-pipe clamp, assembly device and assembly method thereof. Background Technology
[0002] With the deepening of lightweight and integrated design in automobiles, the interior space layout is becoming increasingly compact, and various pipes (such as fuel supply pipes, air conditioning refrigerant pipes, hydraulic brake pipes, etc.) need to be densely arranged in a limited space.
[0003] In existing technologies, the aforementioned pipes are typically fixed using the following two methods: Simple binding fixation: Multiple pipes are bundled together using cable ties or rubber sleeves. While this can shorten the length dimension, it has the following significant drawbacks: Poor vibration resistance: High-frequency vibrations during vehicle operation can easily cause friction and wear between pipes, and may even lead to loosening of joints and failure of seals; Weak thermal expansion adaptability: The deformation differences caused by temperature differences in pipes of different materials cannot be effectively compensated, and they may break due to stress concentration after long-term use; Inconvenient maintenance: A single pipe failure requires disassembling the entire binding structure, resulting in low operational efficiency; Insufficient noise control: Abnormal noises caused by pipe resonance directly affect the NVH (noise, vibration, and harshness) performance inside the vehicle.
[0004] Furthermore, while independent single-pipe clamp-on fixing is gradually being adopted—with each pipe individually equipped with clamps or brackets—this results in a large number of parts, cumbersome assembly processes, and significant space occupation. The current automotive industry is moving towards electrification, intelligentization, and platform modularization, placing higher demands on the integration, lightweighting, and maintainability of piping systems. Especially in new energy vehicles, the scenario of high-voltage wiring harnesses and fluid pipelines sharing the same rail is increasing, urgently requiring a new type of dual-pipe fixing device and structural reinforcement designs for special operating conditions to meet the comprehensive requirements of modern automobiles for safety, reliability, and comfort. Summary of the Invention
[0005] The purpose of this invention is to provide a double-pipe clamp, an assembly device, and an assembly method thereof, so as to solve the problem that the existing single-pipe clamps cannot meet the development needs of the automotive industry.
[0006] To solve the above-mentioned technical problems, the present invention provides a double pipe clamp, including a clamp body, and semi-open elastic arms symmetrically arranged on both sides of the clamp body. The clamp body and the semi-open elastic arms on both sides form two clamp channels respectively, which can clamp two automotive pipes at the same time. A locking tongue is provided at the end of the semi-open elastic arm, which constrains the vehicle pipe inside the pipe clamp channel. The pipe clamp channel formed by the pipe clamp body and the semi-open elastic arm is equipped with a damping pad, which elastically wraps the automotive pipe.
[0007] Preferably, the pipe clamp body has a positioning and mounting hole in the middle, and the double pipe clamp is connected to the vehicle body by a bolt passing through the positioning and mounting hole.
[0008] Preferably, the outer side of the damping pad is provided with a plurality of insertion strips, and the insertion strips correspond one-to-one with the insertion slots in the semi-open elastic arm, so that the damping pad is inserted into the semi-open elastic arm in the tube clamp channel. The inner side of the damping pad is provided with multiple deformation grooves, which allows the damping pad to elastically wrap around the automotive pipe.
[0009] The present invention also provides a dual-pipe clamp assembly device, including a feeding platform and an assembly frame; The feeding platform is equipped with a feeding device for continuously supplying damping pads; An assembly fixture is provided below the assembly frame, and the pipe clamp and two damping pads are assembled and formed in the assembly fixture. The assembly frame is arranged on one side of the assembly frame, and the feeding device is connected to the assembly fixture through a feeding channel, thereby conveying the damping pads one by one into the assembly fixture.
[0010] Preferably, the assembly frame is equipped with a pressing mechanism, which presses two damping pads into the semi-open elastic arms on both sides of the pipe clamp body.
[0011] Preferably, the pressing mechanism includes a lifting base, which is vertically raised and lowered along the assembly frame under the action of the screw assembly, and three sets of pneumatic pressure rods are installed side by side on the lifting base, wherein the middle pneumatic pressure rod presses down to fix the pipe clamp body, and the pneumatic pressure rods on both sides press the two damping pads into the semi-open elastic arms on both sides of the pipe clamp body respectively. The three sets of pneumatic pressure rods are independently controlled by cylinders, and the pneumatic pressure rods are connected to the piston rods of the cylinders by springs, so that all three sets of pneumatic pressure rods are elastically press-fitted. The three sets of pneumatic pressure rods are mounted on the same transverse frame, and are moved laterally by transverse cylinders to adjust their horizontal position.
[0012] Preferably, the feeding channels are symmetrically arranged in the first channel and the second channel. One end of the feeding channel is connected to the feeding device, and the other end is connected to the assembly fixture. The first channel and the second channel provide damping pads simultaneously.
[0013] Preferably, the assembly fixture has a pressing groove for accommodating the pipe clamp body to be pressed, and the upper surface of the pipe clamp body placed in the pressing groove is flush with the feeding channel, so that the damping pad can move along the upper surface of the pipe clamp body to above the pipe clamp channel. The pressing groove has arc-shaped positioning blocks on both sides for positioning the two sides of the pipe clamp body; the middle is a positioning protrusion, which is embedded in the weight reduction groove in the middle of the pipe clamp body for positioning the middle part of the pipe clamp body.
[0014] Preferably, a loading / unloading cylinder is provided on the side of the assembly fixture away from the feeding channel. The piston rod of the loading / unloading cylinder is connected to the assembly fixture through a loading / unloading sliding seat. Under the action of the loading / unloading cylinder, the assembly fixture is driven to slide horizontally for loading the pipe clamp body or unloading the double pipe clamp.
[0015] The present invention also provides a method for press-fitting a double-tube clamp, comprising the following steps: Step A: First, place the pre-prepared damping pad into the vibratory feeder of the feeding device, and continuously push the damping pad into the feeding channel under the continuous operation of the vibratory feeder. Step B: The damping pad is split into two in the feeding channel and pushed forward simultaneously along the first channel and the second channel to the assembly fixture; Step C: Next, the loading and unloading cylinders drive the assembly fixture away from the feeding channel, and the pipe clamp is placed into the pressing groove of the assembly fixture by manual labor or a robotic arm. When the pipe clamp is placed into the press-fitting groove, the two sides are positioned by contact with the arc-shaped positioning blocks, and the weight-reducing groove in the middle is positioned by contact with the positioning protrusion. Step D: Subsequently, the loading and unloading cylinders drive the assembly fixture to approach the feeding channel. At this time, the first channel and the second channel simultaneously push the damping pad forward to the upper surface of the pipe clamp body. Step E: Then, the lifting base descends vertically along the assembly frame under the action of the screw assembly, so that the three sets of pneumatic pressure rods reach above the damping pad; Step F: Then, the middle pneumatic pressure bar is activated to press down and fix the pipe clamp body. Then, the pneumatic pressure bars on both sides press the two damping pads into the semi-open elastic arms on both sides of the pipe clamp body. Step G: After the pressing is completed, the three sets of pneumatic pressure rods and the screw assembly drive the lifting base to reset; Step H: Finally, the loading and unloading cylinders drive the assembly fixture away from the feeding channel, and the press-fitted double pipe clamps are removed manually or by a robotic arm.
[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. The double-pipe clamp of the present invention forms two clamp channels on both sides through semi-open elastic arms, and a damping pad is set in the clamp channel, which can clamp two automotive pipes at the same time. Compared with the traditional single-pipe clamp, it can not only clamp two automotive pipes at the same time, but also the internal damping pad can tightly wrap the outer wall of the automotive pipe, further improving the clamping stability. In the design of the present invention, the damping pad is inserted into the semi-open elastic arm. By replacing the damping pad with a rubber material, the service life of the double-pipe clamp can be extended. 2. The semi-open elastic arm design on both sides of the double-tube clamp in this invention not only meets the deformation requirements during the pressing of the liner, but also maintains long-term clamping force through rebound force, thus balancing functionality and reliability. 3. The dual-tube clamp assembly device of the present invention achieves automatic sorting, directional conveying and diversion (divided into two channels) of damping pads through the combination design of vibratory feeder and feeding channel, which greatly reduces the need for manual intervention and improves the production cycle. At the same time, the dual channels synchronously push the pads to the assembly station, and with the linkage action of multiple sets of pneumatic pressure rods, the single-piece processing cycle is shortened, which is suitable for mass production. 4. This invention employs a three-stage press-fit logic. First, the central pneumatic pressure bar prioritizes pressing the pipe clamp, establishing a reference plane. Second, the two side pressure bars simultaneously press the gasket into the elastic arm, utilizing sequential control to eliminate accumulated errors. Closed-loop feedback adapts to material performance differences in different batches of gaskets through adjustable pneumatic pressure. The three sets of pneumatic pressure bars are independently controlled; a single component failure does not affect the overall system operation, improving equipment uptime. It significantly improves gasket installation consistency and eliminates the localized stress concentration defects caused by traditional single-stage pressurization. 5. The press-fitting device in this invention, through innovative designs such as automated control, precise positioning, and graded pressure application, improves production efficiency while ensuring the assembly accuracy and product consistency of the double-pipe clamps, making it particularly suitable for high-precision, large-volume, long-cycle stable production scenarios.

Example
[0023] This invention provides a double-pipe clamp; please refer to [link / reference]. Figure 1 and Figure 2 The device includes a pipe clamp body 100, with semi-open elastic arms 200 symmetrically arranged on both sides of the pipe clamp body 100. The pipe clamp body 100 and the semi-open elastic arms 200 on both sides form two pipe clamp channels, which can clamp two automotive pipes simultaneously. A locking tongue 300 is provided at the end of the semi-open elastic arm 200, which constrains the automotive pipe inside the pipe clamp channel. A damping pad 400 is provided in the pipe clamp channel formed by the pipe clamp body 100 and the semi-open elastic arms 200, which elastically wraps the automotive pipe.
[0024] Specifically, the pipe clamp body 100 has a positioning mounting hole 500 in the middle, and the double pipe clamp is connected to the vehicle body by a bolt passing through the positioning mounting hole 500.
[0025] Furthermore, the outer side of the damping pad 400 is provided with a plurality of insertion strips 401, each of which corresponds one-to-one with the insertion slot in the semi-open elastic arm 200, so that the damping pad 400 is inserted into the semi-open elastic arm 200 in the pipe clamp channel; the inner side of the damping pad 400 is provided with a plurality of deformation grooves 402, so that the damping pad 400 elastically wraps around the automotive pipe.
[0026] The double-pipe clamp of this invention forms two clamp channels on both sides through semi-open elastic arms, and a damping pad is set in the clamp channel, which can clamp two automotive pipes at the same time. Compared with the traditional single-pipe clamp, it can not only clamp two automotive pipes at the same time, but also the internal damping pad can tightly wrap the outer wall of the automotive pipe, further improving the clamping stability. In the design of this invention, the damping pad is inserted into the semi-open elastic arm. By replacing the damping pad with a rubber material, the service life of the double-pipe clamp can be extended.
[0027] The present invention also provides an assembly device for dual-pipe clamps; please refer to [link / reference]. Figure 3-7 The assembly includes a feeding platform 1 and an assembly frame 2. The feeding platform 1 is equipped with a feeding device 3 for continuously supplying damping pads 400. An assembly fixture 4 is provided below the assembly frame 2, and the pipe clamp 100 and two damping pads 400 are assembled in the assembly fixture 4. The assembly frame 2 is located on one side of the assembly frame 2, and the feeding device 3 is connected to the assembly fixture 4 through a feeding channel 5, thereby conveying the damping pads 400 one by one into the assembly fixture 4.
[0028] For details, please refer to Figure 8 The assembly frame 2 is equipped with a pressing mechanism 6, which presses two damping pads 400 into the semi-open elastic arms 200 on both sides of the pipe clamp body 100.
[0029] For further details, please refer to Figure 9 The pressing mechanism 6 includes a lifting base 61, which is vertically raised and lowered along the assembly frame 2 under the action of the screw assembly 62. Three sets of pneumatic pressure rods 63 are installed side by side on the lifting base 61. The middle pneumatic pressure rod 63 presses down to fix the pipe clamp body 100, and the pneumatic pressure rods 63 on both sides press the two damping pads 400 into the semi-open elastic arms 200 on both sides of the pipe clamp body 100.
[0030] In this embodiment, the three sets of pneumatic pressure rods 63 are independently controlled by cylinders, and the pneumatic pressure rods 63 are connected to the piston rods of the cylinders by springs, so that the three sets of pneumatic pressure rods 63 are all elastically press-fitted.
[0031] In this embodiment, the initial positions of the pneumatic pressure rods 63 on both sides are at the same level, while the initial position of the middle pneumatic pressure rod 63 is lower than the initial positions of the pneumatic pressure rods 63 on both sides. During actual pressing, the middle pneumatic pressure rod 63 first contacts the pipe clamp body 100 and fixes its position. Then, the pneumatic pressure rods 63 on both sides simultaneously contact the two damping pads 400 and are pressed into the semi-open elastic arms 200 on both sides of the pipe clamp body 100.
[0032] In this embodiment, three sets of pneumatic pressure rods 63 are mounted on the same transverse frame, and the transverse cylinder 64 drives the three sets of pneumatic pressure rods 63 to move laterally, so as to adjust the horizontal position of the three sets of pneumatic pressure rods 63.
[0033] For details, please refer to Figure 12 The feeding channels 5 are symmetrically arranged in the first channel 501 and the second channel 502. One end of the feeding channel 5 is connected to the feeding device 3, and the other end is connected to the assembly fixture 4. The first channel 501 and the second channel 502 simultaneously provide damping pads 400. Since a double-pipe clamp requires two damping pads, providing damping pads simultaneously through two channels can further improve the efficiency of press fitting.
[0034] For details, please refer to Figure 13 The assembly fixture 4 has a pressing groove 401 for accommodating the pipe clamp body 100 to be pressed, and the upper surface of the pipe clamp body 100 placed in the pressing groove 401 is flush with the feeding channel 5, so that the damping pad 400 can move along the upper surface of the pipe clamp body 100 to above the pipe clamp channel.
[0035] Furthermore, the two sides of the pressing groove 401 are arc-shaped positioning blocks 402, which are used to position the two sides of the pipe clamp body 100; the middle is a positioning protrusion 403, which is embedded in the weight reduction groove in the middle of the pipe clamp body 100, and is used to position the middle of the pipe clamp body 100.
[0036] For details, please refer to Figure 10 and Figure 11 The pressing groove 401 has arc-shaped positioning blocks 402 on both sides for positioning the two sides of the pipe clamp body 100; the middle is a positioning protrusion 403, which is embedded in the weight reduction groove in the middle of the pipe clamp body 100 for positioning the middle part of the pipe clamp body 100.
[0037] The dual-pipe clamp assembly device of the present invention achieves automatic sorting, directional conveying and diversion of damping pads by combining a vibratory feeder and a feeding channel. The pads are divided into two channels, which greatly reduces the need for manual intervention and improves the production cycle. At the same time, the two channels synchronously push the pads to the assembly station, and with the linkage action of multiple pneumatic pressure rods, the single-piece processing cycle is shortened, making it suitable for mass production.
[0038] The present invention also provides a method for assembling a double-tube clamp, comprising the following steps: Step A: First, place the pre-prepared damping pad 400 into the vibratory feeder of the feeding device 3, and continuously push the damping pad 400 to the feeding channel 5 under the continuous operation of the vibratory feeder. Step B: The damping pad 400 is split into two in the feeding channel 5 and pushed forward simultaneously along the first channel 501 and the second channel 502 to the assembly fixture 4. Step C: Next, the loading and unloading cylinder 7 drives the assembly fixture 4 away from the feeding channel 5, and the pipe clamp body 100 is placed into the pressing groove 401 of the assembly fixture 4 by manual labor or a robotic arm. When the pipe clamp 100 is placed into the press-fit groove 401, the two sides are in contact with the arc-shaped positioning block 402 for positioning, and the weight reduction groove in the middle is in contact with the positioning protrusion 403 for positioning. Step D: Subsequently, the loading and unloading cylinder 7 drives the assembly fixture 4 to approach the feeding channel 5. At this time, the first channel 501 and the second channel 502 simultaneously push the damping pad 400 forward to the upper surface of the pipe clamp body 100. Step E: Then, the lifting base 61 descends vertically along the assembly frame 2 under the action of the screw assembly 62, so that the three sets of pneumatic pressure rods 63 reach above the damping pad 400. Step F: Then, the middle pneumatic pressure rod 63 is activated to press down and fix the pipe clamp body 100. Then, the pneumatic pressure rods 63 on both sides press the two damping pads 400 into the semi-open elastic arms 200 on both sides of the pipe clamp body 100. Step G: After the pressing is completed, the three sets of pneumatic pressure rods 63 and the screw assembly 62 drive the lifting base 61 to reset; Step H: Finally, the loading and unloading cylinder 7 drives the assembly fixture 4 away from the feeding channel 5, and the press-fitted double pipe clamp is removed manually or by a robotic arm.
[0039] This invention employs a three-stage press-fit logic. First, the central pneumatic pressure bar prioritizes pressing the pipe clamp, establishing a reference plane. Second, the two side pressure bars simultaneously press the gasket into the elastic arm, utilizing sequential control to eliminate accumulated errors. Closed-loop feedback adapts to differences in material properties between different batches of gaskets through adjustable pneumatic pressure. The three sets of pneumatic pressure bars are independently controlled, ensuring that a single component failure does not affect the overall system operation, thus improving equipment uptime.
