Description

Technical Field

[0001] This utility model relates to the field of multi-station quick-clamping technology for hoses, specifically, to an airtight constant pressure machine for multi-station quick-clamping of brake hoses. Background Technology

[0002] In the production and processing of hoses, multi-station airtightness pressure testing machines are common equipment used to check whether hoses meet airtightness requirements. This type of equipment typically employs multiple stations working in parallel to improve production efficiency while ensuring the independence and accuracy of the airtightness testing and pressure testing processes at each station.

[0003] According to the public announcement (Announcement No.: CN206509776U), a multi-station integrated quick-change clamping device for machining the end of a long-slit waveguide includes a clamping integrated table, an auxiliary support bracket, a quick-locking pin, a quick-clamping module, a double-table vise, a gap positioning block, a waveguide opening positioning module, and a pressure plate. The waveguide is clamped using the double-table vise, gap positioning block, waveguide opening positioning module, and pressure plate. The device has a simple structure, rapid positioning and clamping, and can clamp two workpieces at a time. It integrates clamping and positioning modules for three processes: milling the steps at both ends, milling the flange end face, and drilling holes in the flange end face. It enables rapid and efficient replacement of clamping modules and fast workpiece changeover.

[0004] In the aforementioned application, although the waveguide can be clamped by the cooperation of components such as double-faced vises and gap positioning blocks, it is difficult to solve the problem of stable and adaptable fixing function when processing the end of long-cracked waveguides and performing multi-process continuous processing of waveguides with different specifications and crack morphologies. This causes the waveguide to easily shift position during processing, affecting processing accuracy and process connection efficiency. Therefore, we propose a multi-station clamping device for processing the end of long-cracked waveguides with adaptive adjustment function. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides an airtight pressure-regulating machine for multi-station quick clamps of brake hoses, which solves the technical problem that the existing technology cannot fix the hoses stably and adaptably.

[0006] According to one aspect, at least one embodiment of the present invention provides an airtight pressure regulating machine for a multi-station quick clamp for brake hoses, comprising: a workbench, a testing platform fixedly connected to the top of the workbench, an insertion port provided on the side of the testing platform, and a fixing device provided on the top of the workbench.

[0007] The fixing device includes a support rod, the side of which is fixedly connected to the side of the workbench. A motor is fixedly connected to the side of the support rod, and a rotating shaft is fixedly connected to the output shaft of the motor. A fixing plate passes through one end of the rotating shaft, and a gear is fixedly connected to the circumference of the rotating shaft. A force-bearing plate is fixedly connected to the side of the gear, and a spring is fixedly connected to the side of the force-bearing plate. A connecting plate is fixedly connected to one end of the spring, and a cover plate is fixedly connected to one end of the connecting plate. A fixing platform is fixedly connected to the top of the workbench, and a fixing clamp is fixedly connected to the side of the fixing platform. An adjusting spring is fixedly connected to the inner wall of the fixing clamp, and a force-bearing block is fixedly connected to the end of the adjusting spring away from the fixing clamp. A sliding groove is provided on the side of the fixing plate. The main function of this device is to achieve stable fixing of objects or equipment through components such as the support rod, motor, and threaded rod. The motor drives the relevant components by rotating the threaded rod. The function of this device is to provide an adjustable and stable fixing platform, supporting tube insertion operations, equipment testing, and various experimental operations. It can ensure the stability and adaptability of objects through mechanical adjustment.

[0008] For example, in at least one embodiment of the present invention, an airtight pressure regulating machine for a multi-station quick clamp for a brake hose is provided, which further includes: the connecting plate is shaped as an arc and the slide groove is shaped as an arc. The arc-shaped connecting plate can better adapt to contact with other components such as force plates or cover plates. Especially when making adjustments, the arc shape can provide a uniform force distribution, reduce the impact of uneven forces on the equipment, and thus improve the stability of the fixation.

[0009] The side of the connecting plate extends through the side of the slide groove, and the cover plate is rotatably connected to the fixing clamp. The fact that the connecting plate extends through the side of the slide groove indicates that the connecting plate can move or slide along its track within the slide groove. This design allows for adjustment of the position of the fixing device, enabling adjustments to its position or angle as needed. By sliding, the connecting plate can precisely control the position of other components, thus achieving more flexible fixing or locking functions.

[0010] Several adjusting springs are arranged in a circumferential array on the inner wall of the fixed clamp, and several force-bearing blocks are also provided. Through the coordinated action of multiple adjusting springs and force-bearing blocks, the force is evenly distributed when the clamp is holding an object, improving the stability and adaptability of the clamping force, while avoiding excessive localized force or damage to the object. This design effectively improves the performance, adaptability, durability, and operational stability of the clamp.

[0011] The number of inspection stations is set to three, and they are arranged in a linear array on the top of the workbench. The side of the fixing station is located on the side of the inspection station. The number of fixing stations is set to three, and they are arranged in a linear array on the top of the workbench. It is necessary to perform inspection and fixing operations on multiple objects at the same time. Especially in the production line with rapid batch processing, multiple inspection stations and fixing stations can ensure that these operations are carried out synchronously, thereby improving the working efficiency of the entire system.

[0012] Three support rods are arranged in a linear array along the side of the worktable, and three motors are also arranged in a linear array along the side of the support rods. By distributing the support rods and motors in a linear array, better structural stability can be provided, especially during long-term operation, to prevent machine shifting or deformation. Multiple support points can effectively distribute the weight of the machine and the pressure during operation, ensuring stable operation of the equipment.

[0013] According to another aspect, at least one embodiment of this utility model also provides an airtight pressure regulating machine for a multi-station quick-clamping brake hose, comprising: a pushing device provided on the side of the fixed plate, the pushing device including a threaded rod, one end of the threaded rod being fixedly connected to the top end of a rotating shaft, a threaded sleeve being threadedly connected to the circumferential surface of the threaded rod, a plug being fixedly connected to the circumferential surface of the threaded sleeve, and a limiting rod being slidably connected to the circumferential surface of the threaded sleeve. The threaded rod is typically used to provide linear motion, driving the threaded sleeve to move along the length of the rod through rotation. The design of the pushing device mainly achieves precise linear adjustment through a threaded mechanism, combined with the limiting rod and the plug to ensure the stability and safety of the device. Its function may be to precisely push or adjust the position of a component during a specific working process, while ensuring the performance of the entire system in terms of accuracy and stability.

[0014] For example, in at least one embodiment of this utility model, an airtight pressure regulating machine for a multi-station quick-clamp brake hose further includes: the bottom end of the limiting rod is fixedly connected to the side of the fixed plate, and the top end of the threaded rod is located on the side of the fixed platform. This structural design helps to improve the stability, accuracy, and reliability of the system. The limiting rod restricts excessive movement of the threaded sleeve, ensuring that the device operates within a reasonable range, while the connection between the top end of the threaded rod and the fixed platform provides necessary support and guidance, ensuring the precise operation of the entire push system. In this way, the system can perform its intended function efficiently and accurately, while avoiding accidental mechanical shocks or deviations.

[0015] The system comprises three threaded rods arranged in a linear array on the side of the fixed plate, and three threaded sleeves arranged in a linear array on the circumference of the threaded rods. This multi-station arrangement of the three threaded rods and three threaded sleeves significantly improves the system's efficiency, accuracy, load balancing capability, and flexibility. It not only effectively reduces working time and avoids the burden on a single station, but also ensures the system maintains high efficiency and stable operation when handling multiple tasks, while simultaneously improving the overall reliability and lifespan of the equipment.

[0016] The number of limiting rods is three, arranged linearly on the side of the fixed plate. The side of the plug is located on the side of the fixed platform. Through reasonable arrangement and fixing, precise positioning, operational independence, load distribution, stability, and accuracy during operation can be guaranteed, thus improving the efficiency and reliability of the overall system. By operating multiple stations in parallel, processing or assembly time can be greatly reduced, while improving the durability of the equipment and the level of automation of the system.

[0017] The beneficial effects of the embodiments of this utility model are as follows:

[0018] In this invention, the supporting rod, motor, threaded rod, fixing plate, gear, force plate, spring, cover plate, fixing platform, fixing clamp, adjusting spring, force block, and slide groove are used in conjunction with each other. The adjusting spring and force block are distributed in a circumferential array along the inner wall of the fixing clamp, and multiple force points form a uniform clamping force. This can firmly fix objects of different specifications and avoid damage to objects caused by excessive local force, thus improving the adaptability to objects of various shapes and sizes. The cooperation between the arc-shaped connecting plate and the arc-shaped slide groove makes the parts contact more closely and the force distribution more uniform. The motor drives the threaded rod to rotate, which drives the gear, force plate and other parts to move together. Combined with the sliding design of the connecting plate in the slide groove, the position and angle of the cover plate and the fixing clamp can be precisely adjusted, so as to achieve flexible control of the fixing force and range.

[0019] In this invention, the threaded rod, threaded sleeve, plug, and limiting rod work together to achieve a threaded connection structure between the threaded rod and the threaded sleeve. Utilizing the characteristics of threaded transmission, precise control of linear motion is achieved. The position of the threaded sleeve and plug can be precisely adjusted by rotating the threaded rod. For high-precision requirements on the pushing distance of components, the limiting rod effectively restricts the movement range of the threaded sleeve, preventing collisions or system malfunctions due to excessive movement. It also provides guidance for the sliding of the threaded sleeve, reducing offset errors and further ensuring the stability and accuracy of the adjustment process. The three threaded rods, threaded sleeve, and limiting rod are linearly arrayed along the side of the fixed plate, forming three independent pushing stations. This allows for simultaneous pushing and adjustment of multiple objects or components, matching the device's multi-inspection and multi-fixed-station design, and enabling parallel processing of fixing, inspection, and pushing procedures.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0029] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0034] like Figures 1-6 As shown, it illustrates an airtight pressure regulating machine for a multi-station quick clamp of a brake hose according to an embodiment of the present invention, including: a workbench 1, a testing platform 2 fixedly connected to the top of the workbench 1, a tube insertion port 3 opened on the side of the testing platform 2, and a fixing device 4 provided on the top of the workbench 1.

[0035] In some examples, the fixing device 4 includes a support rod 41, the side of which is fixedly connected to the side of the workbench 1. A motor 42 is fixedly connected to the side of the support rod 41. The output shaft of the motor 42 is fixedly connected to a rotating shaft 43. One end of the rotating shaft 43 passes through a fixing plate 44. A gear 45 is fixedly connected to the circumferential surface of the rotating shaft 43. A force-bearing plate 46 is fixedly connected to the side of the gear 45. A spring 47 is fixedly connected to the side of the force-bearing plate 46. One end of the spring 47 is fixedly connected to a connecting plate 48. One end of the workbench 8 is fixedly connected to a cover plate 49. A fixed platform 410 is fixedly connected to the top of the workbench 1. A fixed clamp 411 is fixedly connected to the side of the fixed platform 410. An adjusting spring 412 is fixedly connected to the inner wall of the fixed clamp 411. A force-bearing block 413 is fixedly connected to the end of the adjusting spring 412 away from the fixed clamp 411. A sliding groove 414 is provided on the side of the fixed plate 44. The main function of this device is to achieve stable fixation of objects or equipment through components such as the support rod 41, motor 42, and rotating shaft 43. The motor 42 drives the relevant components by rotating the rotating shaft 43. The function of this device is to provide an adjustable and stable fixed platform to support tube insertion operations, equipment testing, and various experimental operations. It can ensure the stability and adaptability of objects through mechanical adjustment.

[0036] For example, in at least one embodiment of the present invention, a brake hose multi-station quick clamp airtight pressure regulating machine is provided, which further includes: the connecting plate 48 is shaped as an arc and the slide groove 414 is shaped as an arc. The arc-shaped connecting plate 48 can better adapt to the contact with other components such as the force plate 46 or the cover plate 49. Especially when making adjustments, the arc shape can provide a uniform force distribution, reduce the impact of uneven force on the equipment, and thus improve the stability of the fixation.

[0037] The side of the connecting plate 48 extends through the side of the slide groove 414, and the cover plate 49 is rotatably connected to the fixing clip 411. The fact that the side of the connecting plate 48 extends through the side of the slide groove 414 indicates that the connecting plate 48 can move or slide along its track within the slide groove 414. This design allows for adjustment of the position of the fixing device 4, enabling it to be adjusted in position or angle as needed. By sliding, the connecting plate 48 can precisely control the position of other components, thus achieving a more flexible fixing or locking function.

[0038] Several adjusting springs 412 are arranged in a circumferential array on the inner wall of the fixed clamp 411, and several force-bearing blocks 413 are fixedly connected to one end of the adjusting springs 412. Through the coordinated action of multiple adjusting springs 412 and force-bearing blocks 413, the force is evenly distributed when the clamp is holding an object, improving the stability and adaptability of the clamping force, while avoiding excessive local force or damage to the object. This design effectively improves the performance, adaptability, durability, and operational stability of the clamp.

[0039] There are three inspection stations 2, arranged in a linear array on top of the workbench 1. The fixed stations 410 are located on the side of the inspection stations 2. There are also three fixed stations 410, arranged in a linear array on top of the workbench 1. Multiple objects need to be inspected and fixed simultaneously. Especially in production lines with rapid batch processing, multiple inspection stations 2 and fixed stations 410 can ensure that these operations are performed synchronously, improving the efficiency of the entire system.

[0040] There are three support rods 41 arranged in a linear array on the side of the worktable 1, and three motors 42 arranged in a linear array on the side of the support rods 41. By distributing the support rods 41 and motors 42 in a linear array, better structural stability can be provided, especially during long-term operation, to avoid machine offset or deformation. Multiple support points can effectively share the weight of the machine and the pressure during operation, ensuring stable operation of the equipment.

[0041] For example, such as Figures 1-6 As shown, the base of the entire device is a workbench 1, on which three testing platforms 2 are mounted. Each testing platform 2 has a fixing platform 410 next to it. The fixing device 4 can fix three hoses at the same time, making it convenient to perform airtightness testing together. First, the hose is placed into the fixing clamp 411. There is an adjusting spring 412 on the inner wall of the fixing clamp 411. Each adjusting spring 412 is connected to a force-bearing block 413. After the hose is placed in, the adjusting spring 412 will automatically extend and retract according to the thickness of the hose, so that the force-bearing block 413 is tightly attached to the hose. The motor 42 is started, which will drive the rotating shaft 43 to rotate. The connecting plate 48 passes through the sliding groove 414 on the fixing plate 44. Because both are curved, the connecting plate 48 can slide along the sliding groove 414, causing the cover plate 49 to rotate towards the fixing clamp 411. Finally, the cover plate 49 and the fixing clamp 411 close together, fixing the hose. There is a tube insertion port 3 on the side of the testing platform 2. The fixed hose can be connected to the testing equipment from here, so that the hose can be tested for air leakage. The components of the Chinese 3 system are arranged side by side, allowing it to handle three hoses simultaneously.

[0042] like Figures 1-6As shown, this invention illustrates a multi-station quick-clamp airtight pressure regulating machine for brake hoses, according to another embodiment of the present invention. The machine includes a pushing device 5 disposed on the side of a fixed plate 44. The pushing device 5 includes a threaded rod 51, a threaded sleeve 52 threadedly connected to the circumferential surface of the threaded rod 51, a plug 53 fixedly connected to the circumferential surface of the threaded sleeve 52, and a limiting rod 54 slidably connected to the circumferential surface of the threaded sleeve 52. The threaded rod 51 is typically used to provide linear motion, driving the threaded sleeve 52 to move along the length of the rod through rotation. The design of the pushing device 5 primarily achieves precise linear adjustment through a threaded mechanism, while the limiting rod 54 and plug 53 ensure the stability and safety of the device. Its function may be to precisely push or adjust the position of a component during a specific working process, while ensuring the overall system's performance in terms of accuracy and stability.

[0043] In some examples, the bottom end of the limiting rod 54 is fixedly connected to the side of the fixed plate 44, and the top end of the threaded rod 51 is located on the side of the fixed platform 410. This structural design helps improve the stability, accuracy, and reliability of the system. The limiting rod 54 restricts excessive movement of the threaded sleeve 52, ensuring that the device operates within a reasonable range, while the engagement of the top end of the threaded rod 51 with the fixed platform 410 provides the necessary support and guidance, ensuring the precise operation of the entire actuation system. In this way, the system can perform its intended function efficiently and accurately while avoiding accidental mechanical shocks or deviations.

[0044] Three threaded rods 51 are arranged in a linear array on the side of the fixed plate 44, and three threaded sleeves 52 are arranged in a linear array on the circumferential surface of the threaded rods 51. This linear array of three threaded rods 51 and three threaded sleeves 52 forms a multi-station configuration, which significantly improves the system's efficiency, accuracy, load balancing capability, and flexibility. It not only effectively reduces working time and avoids the burden on a single station, but also ensures that the system maintains high efficiency and stable operation when handling multiple tasks, while simultaneously improving the overall reliability and service life of the equipment.

[0045] Three limit rods 54 are arranged in a linear array on the side of the fixed plate 44, and the side of the plug 53 is located on the side of the fixed platform 410. Through reasonable arrangement and fixing, precise positioning, operational independence, load distribution, stability, and accuracy during operation can be guaranteed, thus improving the efficiency and reliability of the overall system. By operating multiple stations in parallel, processing or assembly time can be greatly reduced, while improving the durability of the equipment and the level of automation of the system.

[0046] For example, such as Figures 1-6As shown, the pushing device 5 is mounted on the side of the fixed plate 44. When the motor 42 is started, the motor 42 drives the threaded rod 51 to rotate. The threaded sleeve 52 is threadedly connected to the threaded rod 51. So when the threaded rod 51 rotates, the threaded sleeve 52 will move back and forth along the length of the threaded rod 51. The plug 53 is fixed on the threaded sleeve 52. When the threaded sleeve 52 moves, the plug 53 will also move with it. The plug 53 faces the side of the fixed platform 410. When it moves, it can plug the bottom end of the hose on the fixed platform 410, which is convenient for docking with the insertion port 3 of the test platform 2. The bottom end of the limiting rod 54 is fixed on the fixed plate 44. The threaded sleeve 52 is fitted on the limiting rod 54 and can slide along the limiting rod 54. When the threaded sleeve 52 moves, it can only move in a straight line to ensure that the direction of the plug 53 is accurate.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
