Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of automotive hose fixing, specifically to a quick-clamping device for marking automotive hoses. Background Technology

[0002] In the automotive manufacturing industry, key components such as air conditioning, cooling systems, and power steering all rely on hoses for media transmission. Hose, with its flexibility, ease of cutting, prefabrication, and flexible assembly, has become an indispensable basic component of automobiles. Product markings, as an important carrier of information, not only visually display production dates, brand trademarks, and manufacturers, but also play a crucial role in precise positioning during automotive hose assembly. Therefore, marking at hose joints is of paramount importance.

[0003] However, current automotive hose marking technology has significant limitations. Existing marking equipment mostly uses fixed clamps and planar positioning structures, which struggle to achieve stable clamping and precise positioning when dealing with irregularly shaped hoses. This makes it highly susceptible to hose slippage during marking, leading to misaligned or blurred markings and severely impacting product quality. Particularly for hoses that exhibit complex curved shapes after vulcanization, the adaptability of traditional equipment decreases further due to changes in material hardness and deformation characteristics, failing to meet diverse production needs. Furthermore, the lack of equipment versatility necessitates companies configuring dedicated marking devices for different types of hoses, increasing equipment procurement and maintenance costs, and the frequent changes in tooling and fixtures significantly reduce production efficiency.

[0004] Therefore, developing a marking and fixing device that can adapt to various irregularly shaped hoses and has high versatility has become an urgent technical problem to be solved in the automotive parts manufacturing industry. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a quick clamping device for marking automotive hoses, which solves the technical problem that existing marking equipment mostly uses fixed clamps and planar positioning structures, which makes it difficult to achieve stable clamping and accurate positioning when facing irregularly shaped tubes. This makes it easy for the marking to be offset or blurred due to the sliding of the hose during the marking process, which seriously affects the product quality.

[0006] According to one aspect, at least one embodiment of this disclosure provides a quick-clamping device for marking automotive hoses, comprising: A fixed base and a pair of sleeves, both of which are disposed outside the fixed base; A clamping assembly is disposed between the fixed base and the sleeve; The fastening assembly includes a pair of splicing slots, both of which are formed at both ends of the surface of the fixed base. The sleeve is vertically inserted into the splicing slots, and each sleeve is provided with an active sleeve block. A pair of support studs are screwed into the fixed base, and one end of the support studs is rotatably fitted with the active sleeve block.

[0007] As a further technical solution, the surface of the active sleeve block is provided with a number of stabilizing rods, all of which are movably fitted into the sleeve frame, and the inner surface of the sleeve frame is provided with a groove.

[0008] As a further technical solution, the groove is movably fitted with several movable frames, one end of each movable frame is provided with a support block, and a pair of support springs are fitted onto each movable frame, with the support springs supporting the support block between the support block and the inner wall of the groove.

[0009] As a further technical solution, a rectangular opening is provided on the surface of the fixed base, and a pair of inner rods are provided in the rectangular opening. A limit stop is movably connected to the inner rod, and the limit stop covers the top of the connection between the splicing groove and the sleeve. A pressure spring is fitted on the inner rod.

[0010] As a further technical solution, the connection between the splicing groove and the frame is L-shaped, and the bottom of the splicing groove is sealed.

[0011] As a further technical solution, the inner surface of the active sleeve block and the inner end face of the support block are both anti-slip structural surfaces with high friction.

[0012] As a further technical solution, the fixing base has side grooves on both sides, and a pair of round holes are formed in the side grooves.

[0013] As a further technical solution, the frame has an overall U-shaped structure.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the clamping assembly, through the threaded transmission between the support stud and the active sleeve block, can precisely adjust the clamping force to adapt to irregular automotive hoses of different diameters and shapes, solving the problem that traditional fixing fixtures cannot stably clamp irregular hoses. When the active sleeve block pushes the movable frame and support block to clamp the hose circumferentially, the elastic buffer of the support spring avoids hose deformation or damage caused by hard compression. The anti-slip structural surface increases the friction with the hose, preventing the hose from slipping during marking, ensuring accurate marking position, and avoiding product quality issues caused by offset or blurriness. At the same time, the self-adaptive characteristics of the support spring allow the fixture to be compatible with various hose specifications, reducing tooling change frequency and improving production efficiency.

[0023] like Figures 1-3 As shown, it illustrates a quick-clamping device for marking automotive hoses according to an embodiment of this disclosure, comprising: A fixed base 1 and a pair of sleeves 2, wherein the sleeves 2 are both disposed outside the fixed base 1; A fastening assembly 3 is disposed between the fixed base 1 and the sleeve 2; The fastening assembly 3 includes a pair of splicing slots 3-1, each of which is formed at both ends of the surface of the fixed base 1. The sleeve 2 is vertically inserted into the splicing slots 3-1. Each sleeve 2 is provided with an active sleeve block 3-2. A pair of support studs 3-3 are threadedly connected to the fixed base 1. One end of each support stud 3-3 is rotatably fitted with the active sleeve block 3-2. The surface of the active sleeve block 3-2 is provided with several stabilizing rods 3-4, which are movably fitted into the sleeve 2. The inner surface of the sleeve 2 is provided with a groove 3-5. The movable set is connected to several movable frames 3-6. One end of each movable frame 3-6 is provided with a support block 3-7. A pair of support springs 3-8 are mounted on each movable frame 3-6. The support springs 3-8 are supported between the support block 3-7 and the inner wall of the groove 3-5. The surface of the fixed base 1 has a rectangular opening 3-9. A pair of inner rods 3-10 are provided in the rectangular opening 3-9. A limit stop 3-11 is movably mounted on the inner rods 3-10. The limit stop 3-11 covers the top of the connection between the splicing groove 3-1 and the set 2. A pressure spring 3-12 is mounted on the inner rods 3-10.

[0024] In some examples, to achieve stable clamping and flexible protection of automotive hoses, a clamping assembly 3 is designed. This assembly includes a pair of splicing grooves 3-1 formed at both ends of the surface of the fixed base 1, which can connect the sleeve 2 to the fixed base 1. The sleeve 2 is inserted into the splicing grooves 3-1. The two active sleeve blocks 3-2 in the fixed base 1 form a transmission connection with the support studs 3-3 in the fixed base 1. The support studs 3-3 are screwed into the fixed base 1 by threads, and one end is rotated and fitted with the active sleeve blocks 3-2. When the support studs 3-3 are screwed, the thread transmission will push the active sleeve blocks 3-2 to move horizontally within the sleeve 2.

[0025] The stabilizing rod 3-4 on the surface of the active sleeve 3-2 is movably fitted inside the sleeve 2. Through the sliding engagement between the rod and the sleeve 2, the rotation of the active sleeve 3-2 is restricted, ensuring its linear movement in the horizontal direction. In the groove 3-5 on the inner surface of the sleeve 2, the movable frame 3-6 is connected to the inner wall of the groove 3-5 via a support spring 3-8. A support block 3-7 at one end of the movable frame 3-6 contacts the hose, and the elastic thrust of the support spring 3-8 keeps the support block 3-7 in constant contact with the hose surface. When the active sleeve 3-2 moves, it pushes the movable frame 3-6 to slide within the groove 3-5, causing the support block 3-7 to move towards the hose until multiple sets of support blocks 3-7 clamp the hose circumferentially. The buffering effect of the support spring 3-8 prevents the support blocks 3-7 from rigidly squeezing the hose, preventing damage to the hose surface due to uneven force, and also adapts to hoses of different diameters, improving clamping compatibility.

[0026] A limit stop 3-11 is fitted inside the rectangular opening 3-9 on the surface of the fixed base 1, with a pressure spring 3-12 supporting it between the limit stop 3-11 and the bottom of the rectangular opening 3-9, so that the limit stop 3-11 covers the top of the connection between the splicing groove 3-1 and the sleeve 2. The limit stop 3-11 prevents the sleeve 2 from coming out of the splicing groove 3-1, and the elastic downward pressure of the pressure spring 3-12 ensures that the limit stop 3-11 and the sleeve 2 fit tightly, while allowing the sleeve 2 to self-adjust within a small range, avoiding the concentration of clamping stress caused by rigid fixing. The entire clamping assembly 3 forms multiple protections while clamping the tube through the elastic buffer of the support spring 3-8, the flexible contact of the support block 3-7, and the elastic limit of the limit stop 3-11, preventing the tube from deforming or being damaged due to excessive clamping force during the marking process, and ensuring the accuracy of the marking operation and the integrity of the tube.

[0027] For example, such as Figure 1 As shown, the splicing groove 3-1 and the sleeve 2 are connected in an L-shaped structure, and the bottom of the splicing groove 3-1 is sealed.

[0028] In some examples, the connection between the splicing groove 3-1 and the sleeve 2 is L-shaped, and the bottom of the splicing groove 3-1 is sealed. This design enhances the connection stability between the sleeve 2 and the fixing base 1. The vertical and horizontal sections of the L-shape form a right-angle slot. When the sleeve 2 is inserted into the splicing groove 3-1, its bottom abuts against the sealed structure of the horizontal section, and its side fits against the vertical section. The right-angle limit prevents the sleeve 2 from moving in the horizontal or vertical direction. The rigid support of the L-shaped structure allows the sleeve 2 to withstand a large lateral force when clamping the hose, avoiding hose positioning deviation due to the wobbling of the sleeve 2. Combined with the elastic downward pressure of the limiting bracket 3-11, a double anti-detachment structure is formed to ensure that the clamping assembly 3 maintains connection reliability during long-term use.

[0029] For example, such as Figure 1 As shown, the inner surface of the active sleeve block 3-2 and the inner end face of the support block 3-7 are both anti-slip structural surfaces with high friction.

[0030] In some examples, the inner surface of the active sleeve 3-2 and the inner end face of the support block 3-7 are both high-friction, anti-slip structural surfaces. This design balances stability and protection when clamping the hose. The anti-slip structural surfaces are typically made of knurled, mesh-patterned, or rubber materials. By increasing surface roughness, they enhance friction with the hose, preventing slippage due to vibration or external forces during marking and ensuring accurate marking. Simultaneously, the flexible material (such as rubber) of the anti-slip structural surface can conform to the hose surface through elastic deformation, avoiding indentations or damage caused by hard contact. When the active sleeve 3-2 pushes the support block 3-7 to clamp the hose, the friction of the anti-slip structural surface is evenly distributed around the hose. Combined with the buffering effect of the support spring 3-8, the clamping force adapts to the hose diameter, ensuring both clamping effectiveness and preventing damage to the hose surface due to excessive local pressure. This is particularly suitable for thin-walled or easily deformable automotive hoses.

[0031] For example, such as Figure 1 As shown, the fixing base 1 has side grooves 4 on both sides, and a pair of round holes 5 are formed in the side grooves 4.

[0032] In some examples, by providing a side groove 4 and a round hole 5, fasteners such as bolts can pass through the round hole 5, and the mounting base 1 can be securely installed in the usage position.

[0033] For example, such as Figure 1 As shown, the frame 2 has an overall U-shaped structure.

[0034] In some examples, the sleeve 2 has an overall U-shaped structure, which optimizes the ease of loading and unloading the hose and the stability of clamping. The opening of the U-shape faces the direction of hose insertion, allowing operators to directly insert the hose into the sleeve 2 through the opening without disassembling other parts, significantly reducing clamping time. The two arms of the sleeve 2 provide mounting support for components such as the active sleeve block 3-2 and the movable frame 3-6. The inner groove 3-5 cooperates with the movable frame 3-6, allowing the support block 3-7 to clamp the hose from both sides. The bottom of the U-shaped structure abuts against the L-shaped bottom of the splicing groove 3-1, forming a stable support surface. When the active sleeve block 3-2 pushes the movable frame 3-6, the two arms of the U-shaped sleeve 2 can evenly transmit the clamping force, preventing the hose from deforming due to unilateral force.

[0035] In practical use: Fix the mounting base 1 to the marking equipment through the round holes 5 in the side grooves 4 on both sides. Insert a pair of U-shaped sleeves 2 vertically into the L-shaped splicing grooves 3-1 at both ends of the mounting base 1, so that the bottom of the sleeves 2 abuts against the sealing structure in the splicing groove 3-1. Press the limiting stop 3-11 to cover the top of the connection between the splicing groove 3-1 and the sleeve 2. The pressure spring 3-12 elastically presses down in the rectangular opening 3-9 to ensure that the limiting stop 3-11 fits. Insert the automotive hose into the U-shaped opening of the sleeve 2. Tighten the support stud 3-3 in the mounting base 1. The support stud 3-3 pushes the active sleeve 3-2 to move horizontally in the sleeve 2 through the threaded transmission. The stabilizing rod 3-4 on the surface of the active sleeve 3-2 slides and limits in the sleeve 2 to prevent the active sleeve 3-2 from rotating. When the active sleeve 3-2 moves, it pushes the movable frame 3-6 in the groove 3-5. The movable frame 3-6 drives the support block 3-7 to move towards the hose. The support spring 3-8 provides elastic buffering between the support block 3-7 and the inner wall of the groove 3-5, so that the support block 3-7 fits against the surface of the hose and clamps the hose from the circumference. The anti-slip structure of the active sleeve 3-2 and the support block 3-7 increases the friction and prevents the hose from sliding. After clamping is completed, the marking operation is performed. After marking is completed, the support stud 3-3 is turned in the opposite direction. The support spring 3-8 returns to its original position and causes the support block 3-7 to loosen, allowing the hose to be removed.
