Description

Technical Field

[0001] This utility model relates to the field of rubber hose testing technology, specifically a testing device for automotive rubber hoses. Background Technology

[0002] Automotive rubber hoses are key rubber tubular components used in automobiles to transport liquids or gases and connect different parts. They play an important role in many core systems of automobiles, such as cooling systems, fuel systems, braking systems, and air conditioning systems. After the rubber hoses are manufactured, they need to be tested to ensure their sealing performance.

[0003] Announcement No. CN219391275U discloses a sealing performance testing device for rubber hoses. The above patent improves upon the shortcomings of existing sealing performance testing devices, which require separate operation of two sets of clamping structures (inner and outer) to clamp the rubber hose, resulting in cumbersome operation steps. By using a synchronous mechanism to drive the clamping blocks to converge around the inner support, the rubber hose is interference-fitted onto the inner support. Then, by rotating the handle, the screw drives the rack to engage the drive ring, and the inclined groove extrusion connecting rod drives the clamping blocks to clamp the end of the hose. The operation is convenient and the sealing effect is good.

[0004] However, the size of the inner support is fixed. When fitting the rubber tube, the tube body must be pre-opened before the rubber tube can be fitted onto the inner support, which is not convenient to use. Furthermore, the inner support can only fix rubber tubes of a fixed size. If the diameter of the rubber tube is small, it cannot be fitted onto the inner support. If the diameter of the rubber tube is large, it cannot fit well with the inner support after being fitted onto the inner support, resulting in gaps and wrinkles between the rubber tube and the inner support after fixing, which affects the detection effect. Therefore, a detection device for automotive rubber tubes is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a testing device for automotive rubber hoses, which has the advantages of adaptability and good fixing effect. It solves the problems of existing testing devices where the fixed inner support size leads to poor fitting of rubber hoses with too small a diameter, and rubber hoses with too large a diameter are prone to gaps and wrinkles after fitting, resulting in poor fit with the inner support and affecting the testing effect.

[0006] To achieve the above-mentioned objectives of good adaptability and fixation, this utility model provides the following technical solution: a testing device for automotive rubber hoses, comprising a base plate, on which a housing is fixedly mounted, and a rubber hose fixing mechanism extending out of the housing is provided inside the housing; The rubber hose fixing mechanism includes a mounting bracket fixedly installed inside the housing, a first air pipe, and a second air pipe. A rubber hose sleeve connector extending to the outer surface of the housing is fixedly installed at one end of both the first and second air pipes. Two electric telescopic rods with output ends extending to the outside of the housing are fixedly installed on the inner surface of the mounting bracket. A connecting plate is fixedly installed at the output end of each electric telescopic rod. A fixing cylinder is fixedly installed on the surface of the connecting plate. A rubber sleeve is fixedly installed on the inner surface of the fixing cylinder. A pressure gauge is fixedly installed at one end of the first air pipe. An air pump is fixedly installed inside the housing.

[0007] Furthermore, the outer shape of the rubber sleeve joint is conical, the inner surface of the rubber sleeve is inclined, and the inclined surface of the rubber sleeve joint is adapted to the inclined surface of the rubber sleeve.

[0008] Furthermore, the positions of the fixing cylinder and the rubber sleeve correspond to the positions of the rubber tube sleeve joint.

[0009] Furthermore, the end of the second air tube furthest from the rubber tube sleeve joint is connected to the air outlet of the air pump.

[0010] Furthermore, a connecting bend extending to the top of the outer casing and connected to the first air tube is fixedly installed at one end of the first air tube, and the pressure gauge is fixedly installed at the end of the connecting bend away from the first air tube.

[0011] Compared with the prior art, this utility model provides a testing device for automotive rubber hoses, which has the following advantages: This testing device for automotive rubber hoses utilizes the conical design of the rubber hose fitting and the beveled design of the rubber sleeve. This allows the rubber hose fitting to accommodate rubber hoses of different diameters. The conical structure naturally expands the hose and ensures a tight fit, reducing operational difficulty. Simultaneously, the rubber sleeve tightly presses the rubber hose against the surface of the rubber hose fitting, improving the connection stability between the rubber hose and the fitting and preventing gaps. This enhances the efficiency and effectiveness of rubber hose testing. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-3 This embodiment of a testing device for automotive rubber hoses includes a base plate 1, on which a housing 2 is fixedly mounted. Inside the housing 2, a rubber hose fixing mechanism 3 extends to the outside of the housing 2. The rubber hose fixing mechanism 3 includes a mounting bracket 31, a first air pipe 32, and a second air pipe 33, all fixedly mounted inside the housing 2. One end of each of the first air pipe 32 and the second air pipe 33 is fixedly mounted with a rubber hose sleeve connector 34 extending to the outer surface of the housing 2. Two electric telescopic rods 35, each with an output end extending to the outside of the housing 2, are fixedly mounted on the inner surface of the mounting bracket 31. A connecting plate 36 is fixedly mounted on the output end of the electric telescopic rod 35. A fixing cylinder 37 is fixedly mounted on the surface of the connecting plate 36. A rubber sleeve 38 is fixedly mounted on the inner surface of the fixing cylinder 37. A pressure gauge 4 is fixedly mounted on one end of the first air pipe 32. An air pump 5 is fixedly mounted inside the housing 2.

[0016] In this embodiment, the outer shape of the rubber tube sleeve joint 34 is conical, and the inner surface of the rubber sleeve 38 is inclined. The inclined surface of the rubber tube sleeve joint 34 is adapted to the inclined surface of the rubber sleeve 38. Through the adaptation design of the conical shape of the rubber tube sleeve joint 34 and the inclined surface of the rubber sleeve 38, the rubber tube sleeve joint 34 can be adapted to rubber tubes of different diameters. When the rubber tube is sleeved, the conical structure can naturally open the tube body and fit tightly. The rubber sleeve 38 eliminates gaps and wrinkles through the compression of the inclined surface, so that the rubber tube and the rubber tube sleeve joint 34 can fit tightly, avoiding the problem of insecure fixation due to size mismatch, and solving the limitation of traditional internal supports that can only fix a single size.

[0017] In this embodiment, the positions of the fixing cylinder 37 and the rubber sleeve 38 correspond to the positions of the rubber tube joint 34. The electric telescopic rod 35 can drive the fixing cylinder 37 and the rubber sleeve 38 to move closer to the rubber tube joint 34 to fix the rubber tube, which is beneficial to improving the detection efficiency.

[0018] In this embodiment, the end of the second air tube 33 away from the rubber tube sleeve joint 34 is connected to the air outlet of the air pump 5, so that air can be easily injected into the rubber tube after the rubber tube is fixed.

[0019] In this embodiment, a connecting bend 6 extending to the top of the outer shell 2 and connected to the first air tube 32 is fixedly installed at one end of the first air tube 32. A pressure gauge 4 is fixedly installed at the end of the connecting bend 6 away from the first air tube 32. The pressure gauge 4 can monitor the changes in air pressure inside the rubber tube in real time.

[0020] It should be noted that a resistive touch screen controller is fixedly installed on the top of the outer shell 2 in this embodiment. The resistive touch screen controller is electrically connected and controlled to the electric telescopic rod 35 and the air pump 5 through a connecting wire. The resistive touch screen controller can be used to set the value of the air pressure injected into the rubber tube.

[0021] It should be noted that, in this embodiment, the two electric telescopic rods 35 are precisely controlled by a programmable logic controller, and the synchronous movement of the two electric telescopic rods 35 is achieved through programming.

[0022] The working principle of the above embodiments is as follows: In use, the two ends of the rubber tube to be tested are passed through the two fixing cylinders 37 and the rubber sleeves 38 respectively. The two ends of the rubber tube are then fitted onto the two rubber tube fittings 34, so that the rubber tube fittings 34 can open the ends of the rubber tube and make a tight contact between the rubber tube and the rubber tube fittings 34. Then, the connecting plate 36 and the fixing cylinders 37 are moved towards the rubber tube fittings 34 by the electric telescopic rod 35, so that the fixing cylinders 37 are fitted onto the rubber tube fittings 34 and the rubber tube. At this time, the rubber sleeves 38 are tightly fitted to the outer surface of the rubber tube, which can compress the rubber tube and fix the ends of the rubber tube onto the rubber tube fittings 34. The air pump 5 is started, and air is injected into the rubber tube through the air pump 5 and the second air pipe 33. When the air pressure inside the rubber tube reaches the set value, the inflation is stopped. The air pressure change inside the rubber tube is observed by the pressure gauge 4. If the air pressure inside the rubber tube gradually decreases, it is judged that the rubber tube has an air leak and the air tightness is unqualified. Otherwise, it is judged that the air tightness of the rubber tube is qualified.

[0023] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.
