Abstract
Description
Technical Field
[0001] This utility model relates to the field of steering gear technology, and specifically to a quick clamping structure for a steering gear test interface. Background Technology
[0002] The automotive steering gear is a core component of the vehicle's steering system, responsible for converting the rotation of the steering wheel into the steering action of the wheels, directly affecting driving feel and safety. Existing power steering gears require an oil pump to supply oil to and from the steering gear, providing hydraulic assistance to the driver and allowing for flexible control of the wheel's direction. During the manufacturing process, the internal oil supply and return processes must be tested to meet production standards.
[0003] In actual use, when the oil pipe is installed at the corresponding oil inlet and outlet of the steering gear, the oil pipe joint needs to be continuously turned to ensure that the oil pipe joint can be stably connected to the oil inlet and outlet of the steering gear. This prolongs the testing time and results in low oil inlet and outlet testing efficiency of the steering gear.
[0004] Therefore, it is necessary to invent a quick-clamping structure for use in steering gear test interfaces to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a quick clamping structure for the test interface of a steering gear, so as to solve the problem that the testing time is extended, resulting in low efficiency of steering gear oil inlet and outlet testing.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-clamping structure for a steering gear test interface, comprising a steering gear body, an oil inlet connector fixedly connected to the side of the steering gear body, an oil inlet pipe inserted into the inside of the oil inlet connector, and a quick-release assembly provided between the oil inlet connector and the oil inlet pipe, the quick-release assembly comprising an insertion hole, a snap-fit groove, a positioning groove, a sealing gasket, a threaded rod, an abutment block, a sealing plug, a steel ring spring, a disassembly pin, and an adjusting sleeve.
[0007] The quick-release assembly allows for the rapid fixing of the oil inlet pipe inside the oil inlet connector, or the quick removal of the oil inlet pipe from the oil inlet connector, thereby facilitating rapid inspection of the steering gear body and improving inspection efficiency.
[0008] Optionally, the insertion hole is located inside the oil inlet connector, and the abutment block and threaded rod are inserted into the insertion hole.
[0009] By adopting the above technical solution, the abutment block and threaded rod are inserted into the insertion hole, thereby fixing the oil inlet pipe and the oil inlet connector.
[0010] Optionally, an oil inlet is provided at one end of the inner side of the plug hole, and the sealing gasket is fixedly connected to the position of the inner side of the plug hole located on the side of the oil inlet.
[0011] By adopting the above technical solution, after connecting the oil inlet pipe to the oil inlet connector, the oil inlet pipe sends the oil into the interior of the steering gear body through the oil inlet hole.
[0012] Optionally, the snap-fit groove is located on the side wall of the insertion hole near the outer end, and the outer end of the snap-fit groove is provided with an inclined positioning groove.
[0013] Optionally, the surface of the steel coil spring is provided with a notch, and the steel coil spring is engaged inside the positioning groove.
[0014] By adopting the above technical solution, the steel coil spring can expand outward or contract inward under the action of the notch. The positioning groove is used to position the steel coil spring and prevent it from expanding outward.
[0015] Optionally, the threaded rod is fixedly connected to the end of the oil inlet pipe, and the abutment block is fixedly connected to the right end of the threaded rod.
[0016] By adopting the above technical solution, both the threaded rod and the abutment block have through holes for conveying oil. The right side of the abutment block is inclined. After the threaded rod and the abutment block are inserted into the insertion hole, the steel ring spring will be sleeved on the right end of the threaded rod, and the abutment block will limit the steel ring spring to prevent it from falling off, thereby fixing the threaded rod and the abutment block inside the insertion hole.
[0017] Optionally, the disassembly pin is threadedly connected to the surface of the threaded rod, the adjusting sleeve is fixedly connected to the side of the disassembly pin, and the adjusting sleeve is slidably connected to the surface of the threaded rod.
[0018] By adopting the above technical solution, the disassembly pin can be rotated to move left and right on the surface of the threaded rod, thereby causing the adjusting sleeve to slide left and right on the surface of the threaded rod. When the adjusting sleeve slides to the right, its right end will insert into the inside of the steel ring spring, thereby causing the steel ring spring to be pushed outward so that its inner diameter is the same as the outer diameter of the left end of the abutment block. At this time, the threaded rod and the abutment block can be removed from the insertion hole.
[0019] Optionally, the sealing plug is fixedly connected to the right end of the abutment block, and the sealing plug abuts against the surface of the sealing gasket.
[0020] By adopting the above technical solution, the sealing plug and the sealing gasket are tightly connected to prevent oil leakage. At the same time, the sealing gasket has a certain degree of elasticity, which will push the sealing plug, the abutment block and the threaded rod to the right, thereby locking the steel ring spring inside the positioning groove and preventing the steel ring spring from accidentally unfolding, causing the threaded rod and the abutment block to fall off.
[0021] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0022] 1. This utility model involves directly inserting the abutment block and threaded rod into the insertion hole. The steel ring spring passes through the abutment block and is sleeved on the right end of the threaded rod. The abutment block limits the steel ring spring, fixing the threaded rod and abutment block inside the insertion hole, thereby fixing the oil inlet pipe and oil inlet connector. Conversely, rotating the disassembly pin causes the adjusting sleeve to slide to the right. The adjusting sleeve pushes the steel ring spring outward so that its inner diameter is the same as the outer diameter of the left end of the abutment block. At this time, the threaded rod and abutment block can be removed from the insertion hole, effectively improving the efficiency of disassembling and assembling the oil inlet pipe, thereby effectively improving the testing efficiency.
[0023] 2. This utility model uses a sealing plug and a sealing gasket to tightly connect, preventing oil leakage. At the same time, the sealing gasket will push the sealing plug, the abutment block and the threaded rod to the right, thereby locking the steel ring spring inside the positioning groove. The positioning groove limits the outer side of the steel ring spring, preventing the steel ring spring from accidentally expanding and causing the threaded rod and the abutment block to fall off, effectively improving the connection strength and improving the stability and safety of the test.

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0033] This utility model provides, for example Figures 1 to 4 The diagram shows a quick-clamping structure for a steering gear test interface, including a steering gear body 1. An oil inlet connector 2 is fixedly connected to the side of the steering gear body 1. An oil inlet pipe 3 is inserted into the inside of the oil inlet connector 2. A quick-release assembly is provided between the oil inlet connector 2 and the oil inlet pipe 3. The quick-release assembly includes an insertion hole 21, a snap-fit groove 22, a positioning groove 23, a sealing gasket 25, a threaded rod 31, abutment block 32, a sealing plug 33, a steel ring spring 34, a disassembly pin 35, and an adjusting sleeve 36. The insertion hole 21 is opened inside the oil inlet connector 2. The abutment block 32 and the threaded rod 31 are inserted into the insertion hole 21. An oil inlet hole 24 is opened at one end of the inner side of the insertion hole 21.
[0034] During the testing process, the threaded rod 31 and the abutment block 32 are inserted into the insertion hole 21 and locked in place with the steel ring spring 34. Then, the oil inlet pipe 3 is connected to the oil inlet connector 2. At this time, the oil inside the oil inlet pipe 3 can enter the interior of the steering gear body 1 through the oil inlet hole 24, thereby testing the steering gear body 1. With the cooperation of the quick-release assembly, the oil inlet pipe 3 and the oil inlet connector 2 can be quickly connected or separated, improving the convenience of disassembling and assembling the oil inlet pipe 3 and the testing efficiency of the steering gear body 1.
[0035] See Figures 2 to 6 The snap-fit groove 22 is located on the side wall of the insertion hole 21 near the outer end. The outer end of the snap-fit groove 22 is provided with an inclined positioning groove 23. The surface of the steel ring spring 34 is provided with a notch. The steel ring spring 34 is snapped into the inside of the positioning groove 23. The threaded rod 31 is fixedly connected to the end of the oil inlet pipe 3. The abutment block 32 is fixedly connected to the right end of the threaded rod 31. The disassembly pin 35 is threadedly connected to the surface of the threaded rod 31. The adjusting sleeve 36 is fixedly connected to the side of the disassembly pin 35. The adjusting sleeve 36 is slidably connected to the surface of the threaded rod 31. The sealing gasket 25 is fixedly connected to the inner end of the insertion hole 21 located on the side of the oil inlet hole 24. The sealing plug 33 is fixedly connected to the right end of the abutment block 32. The sealing plug 33 abuts against the surface of the sealing gasket 25.
[0036] Specifically, before installing the oil inlet pipe 3, the inner diameter of the insertion hole 21 is smaller than the outer diameter of the steel coil spring 34 but larger than the inner diameter of the steel coil spring 34. First, the steel coil spring 34 is pressed inward to lock it inside the insertion hole 21. Then, it is pushed inward to move it into the locking groove 22 and return it to its normal state. The locking groove 22 and the positioning groove 23 cooperate to limit the position of the steel coil spring 34.
[0037] During the installation of the oil inlet pipe 3, the threaded rod 31, the abutment block 32, and the sealing plug 33 are inserted into the insertion hole 21. The outer diameter of the sealing plug 33 is smaller than the inner diameter of the steel coil spring 34, so it will pass through the inside of the steel coil spring 34. The right end of the abutment block 32 is smaller than the inner diameter of the steel coil spring 34, and the left end of the abutment block 32 is larger than the outer diameter of the steel coil spring 34 but smaller than the outer diameter of the steel coil spring 34, so that the right end of the abutment block 32 will pass through the inside of the steel coil spring 34, causing the steel coil spring 34 to be stuck on the surface of the abutment block 32. As the abutment block 32 is continuously pushed inward, the inclined surface of the abutment block 32 will... Gradually push the steel coil spring 34 outwards until the left end of the abutment block 32 passes through the inside of the steel coil spring 34. At this time, the steel coil spring 34 will return to its original state and be stuck at the right end of the threaded rod 31. The outer diameter of the threaded rod 31 is the same as the inner diameter of the steel coil spring 34. In addition, after releasing the threaded rod 31, the sealing gasket 25 will push the sealing plug 33 to the left, thereby driving the abutment block 32 and the threaded rod 31 to move to the left, locking the steel coil spring 34 inside the positioning groove 23, thereby tightly fixing the threaded rod 31, the abutment block 32 and the sealing plug 33 inside the insertion hole 21, and connecting the oil inlet pipe 3 and the oil inlet connector 2.
[0038] Conversely, when disassembling the oil inlet pipe 3, first push the threaded rod 31, the abutment block 32, and the sealing plug 33 to the right, so that the steel ring spring 34 moves into the inside of the snap-fit groove 22. At this time, rotate the disassembly pin 35 to push the adjusting sleeve 36 to the right. The right end of the adjusting sleeve 36 will push the steel ring spring 34 outward so that its inner diameter is the same as the left end of the abutment block 32. At this time, pull the threaded rod 31, the abutment block 32, and the sealing plug 33 to the left to disengage them from the insertion hole 21, while the steel ring spring 34 remains inside the snap-fit groove 22.
[0039] In another embodiment, the threaded rod 31 can be replaced with a smooth rod, and the disassembly pin 35 and the adjusting sleeve 36 are slidably connected to the smooth rod. When disassembling the oil inlet pipe 3, simply press the disassembly pin 35 and the adjusting sleeve 36 inward to support the steel ring spring 34 so as to adapt to different oil inlet pipes 3 for use.
[0040] The working principle of this utility model is as follows: By directly inserting the abutment block 32 and the threaded rod 31 into the insertion hole 21, the steel ring spring 34 will pass through the abutment block 32 and be sleeved on the right end of the threaded rod 31. The abutment block 32 limits the steel ring spring 34, fixing the threaded rod 31 and the abutment block 32 inside the insertion hole 21, thereby fixing the oil inlet pipe 3 and the oil inlet connector 2. Conversely, by rotating the disassembly pin 35, the adjusting sleeve 36 slides to the right, and the adjusting sleeve 36 pushes the steel ring spring 34 outward so that its inner diameter is the same as the outer side of the left end of the abutment block 32. At this time, the threaded rod 31 and the abutment block 32 can be removed from the insertion hole 21, effectively improving the disassembly and assembly efficiency of the oil inlet pipe 3, thereby effectively improving the detection efficiency.
[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
