Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts testing equipment, specifically to a steering gear sealing testing device. Background Technology

[0002] The steering gear is a key component of a car's steering system. Its main function is to appropriately transform the steering torque and steering angle from the steering wheel, typically by reducing speed and increasing torque before outputting it to the steering tie rod mechanism, thereby achieving vehicle steering. Common steering gear types include rack and pinion, recirculating ball, worm gear crank pin, and power steering. Before leaving the factory, the steering gear's water tightness needs to be tested to ensure proper functioning in actual operation. During testing, the steering gear under test is placed on a fixed platform, and then the steering shaft is connected to the steering gear before testing.

[0003] However, existing steering gear testing equipment has shortcomings. For example, the fixed platform cannot be adjusted in angle, and the steering shaft can only move horizontally and vertically. For some steering gears with tilted interfaces, they cannot be properly connected to the steering shaft on the fixed platform, making it impossible to test this type of steering gear. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a steering gear sealing test device to solve the technical problem that the fixed platform of the existing steering gear test equipment cannot be adjusted in angle, and that some steering gears with tilted interfaces cannot be properly connected to the steering shaft on the fixed platform, thus making it impossible to test this type of steering gear.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: This utility model provides a steering gear sealing test device, comprising: The machine body is equipped with a water tank; A support platform is located in the water tank, and the support platform is rotatably mounted on the machine body; and A steering shaft is rotatably mounted on the machine body and is used to detachably connect the steering gear under test to the support platform.

[0006] In some embodiments, the steering gear sealing test apparatus further includes a drive mechanism connected to the support platform and used to drive the support platform to swing left and right.

[0007] In some embodiments, the drive mechanism includes an adjustment handle, a linkage component, and a transmission belt connected in sequence. The adjustment handle is rotatably connected to the machine body, the linkage component is disposed on the machine body, and the transmission belt connects the linkage component and the support platform.

[0008] In some embodiments, the linkage component includes a first gear and a second gear that mesh with each other. The first gear and the second gear are both rotatably mounted on the machine body and their rotation axes are set at an angle. The first gear is connected to an adjustment handle, and the second gear is connected to the transmission belt.

[0009] In some embodiments, the support platform is provided with a rotating component, which is rotatably mounted on the machine body. One end of the rotating component is connected to the support platform, and the other end of the rotating component has a driven gear that meshes with the transmission belt.

[0010] In some embodiments, the support platform includes a placement platform and a first limiting member, the first limiting member being slidably connected to the placement platform and capable of adjusting the space size for fixing the steering gear under test when sliding.

[0011] In some embodiments, the support platform includes a second limiting member that is slidably connected to the placement platform, and a clamping space for clamping the steering gear under test is formed between the second limiting member and the first limiting member.

[0012] In some embodiments, the support platform further includes a tensioning member disposed on the first limiting member, the tensioning member being threadedly connected to the first limiting member and capable of abutting against or disengaging from the support platform during rotation.

[0013] In some embodiments, the steering gear sealing test device further includes a steering adjustment mechanism, which includes a connecting rod, a moving block, and a motor.

The two ends of the connecting rod are respectively connected to the motor and the moving block, and the moving block is slidably connected to the body.

[0014] In some embodiments, the bottom of the machine body is provided with casters and a drain pipe.

[0015] Compared with existing technologies, the steering gear sealing test device provided by this utility model includes a support platform for placing the steering gear under test. Since the support platform is rotatably mounted on the machine body, after the steering gear under test is placed and fixed on the support platform, the support platform can be driven to rotate according to the required connection angle, so that the inclined interface of the steering gear under test aligns with the steering shaft, thereby completing the connection between the steering shaft and the steering gear under test. After the connection is completed, the steering shaft can be rotated to simulate the actual working state of a car. Water is then added to the water tank until it submerges the connection between the steering gear under test and the steering shaft. The water tightness of the steering gear under test is determined by observing whether there are air bubbles in the water. It can be seen that this application, by rotating the support platform, allows the steering shaft to adapt to the connection of various steering gears with different inclined interfaces, further improving the compatibility of the test.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] To address the technical problem that the fixed platform of existing steering gear testing equipment cannot be adjusted in angle, and that some steering gears with tilted interfaces cannot be properly connected to the steering shaft on the fixed platform, thus preventing the testing of such steering gears, this invention provides a steering gear sealing testing device. This device can rotate and adjust the angle of the fixed platform to adjust the angle of the tilted interface of the steering gear under test, thereby successfully connecting the steering gear under test to the steering shaft.

[0019] It should be noted that the steering gear sealing test device described in this utility model is used for, but not limited to, water tightness testing of automotive steering gears. For ease of explanation, this utility model only uses the application of the steering gear sealing test device to water tightness testing of automotive steering gears as an example for explanation. The principle of the steering gear sealing test device applied to other types of equipment is essentially the same as that applied to automotive steering gears, and will not be elaborated here.

[0020] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a steering gear sealing test device in one embodiment of the present invention. The steering gear sealing test device 100 includes a body 1, a support platform 2 and a steering shaft 3. The body 1 has a water tank 11. The support platform 2 is located in the water tank 11 and is rotatably mounted on the body 1. The steering shaft 3 is rotatably mounted on the body 1 and is used to detachably connect the steering gear to be tested on the support platform 2.

[0021] In this embodiment, the main body 1 serves as the core of the testing device, supporting its various components. The main body 1 primarily comprises a base 12 and a gantry frame 13. The two ends of the gantry frame 13 are connected to the two ends of the base 12, forming a test space 14 between the gantry frame 13 and the base 12. The aforementioned steering shaft 3 is located within the test space 14. A water tank 11 is provided on the top of the base 12. After the steering shaft 3 is connected to the steering gear under test, it is driven to rotate, simulating the actual working state of a car steering system. The steering shaft 3 and the support platform 2 are then lowered into the water tank, placing their connection point in the water tank 11. The water tightness of the steering gear under test is determined by observing whether there are air bubbles in the water tank 11. The gantry frame 13 has a sliding plate 131, on which both the steering shaft 3 and the support platform 2 are mounted. The sliding plate 131 can slide up and down to adjust the height of the steering shaft 3 and the support platform 2. After the steering gear under test has completed the test, the slide plate 131 can be raised to drive the steering shaft 3 and the support platform 2 to detach from the water tank 11, and the steering gear under test can be replaced.

[0022] The gantry frame 13 is equipped with a vertical track 132, a lifting motor 133 and a lifting screw (not shown in the figure). The slide plate 131 is slidably connected to the vertical track 132 through the lifting block 134. The lifting screw is threadedly connected to the slide plate 131. The lifting motor 133 is connected to the lifting screw and can drive the lifting screw to rotate. When the lifting screw rotates, it can drive the slide plate 131 to rise and fall through the thread, thereby adjusting the height of the support platform 2 and driving the steering device under test to enter or leave the water tank 11.

[0023] The two ends of the support platform 2 are rotatably connected to the two sides of the gantry 13, allowing the support platform 2 to swing left and right to adjust the angle of the steering gear under test located on the support platform 2. This is especially suitable for steering gears under test with tilt interfaces. When the tilt interface of the steering gear under test is adjusted to a suitable angle, the tilt interface can be smoothly connected to the steering shaft 3, thereby completing the test of the steering gear under test.

[0024] In one embodiment, please refer to Figure 2 The steering gear sealing test device also includes a drive mechanism 4, which is connected to the support platform 2 and used to drive the support platform 2 to swing left and right. The power source for the swing of the support platform 2 can be manual or electric; in this embodiment, manual is preferred because it is not only energy-saving but also low-cost.

[0025] Further, please refer to Figure 3The drive mechanism 4 includes an adjusting handle 41, a linkage component 42, and a transmission belt 43 connected in sequence. The adjusting handle 41 is rotatably connected to the machine body 1, the linkage component 42 is located on the machine body 1, and the transmission belt 43 connects the linkage component 42 and the support platform 2. By manually operating the adjusting handle 41, the adjusting handle 41 drives the transmission belt 43 to move through the linkage component 42. The transmission belt 43 can easily control the swing angle of the support platform 2, thereby achieving adaptation to the steering gear under test at different tilt angles. It should be emphasized that the drive mechanism 4 is located on the slide plate 131 and can rise and fall synchronously with the slide plate 131. The rise and fall of the slide plate 131 does not affect the operation of the drive mechanism 4.

[0026] In one embodiment, please refer to Figure 3 and Figure 4 The linkage component 42 includes a gearbox 423, a first gear 421, and a second gear 422. Both the first gear 421 and the second gear 422 are bevel gears, enabling the linkage component 42 to transmit forces in different directions. The first gear 421 and the second gear 422 mesh with each other and are both rotatably mounted on the gearbox 423. The rotation axes of the first gear 421 and the second gear 422 are set at an angle, preferably perpendicular to each other, for more stable force transmission. The first gear 421 is connected to the adjusting handle 41, and the second gear 422 is connected to the transmission belt 43. In this embodiment, the rotational motion of the adjusting handle 41 is converted into the linear motion of the transmission belt 43 through gear transmission, thereby realizing the swing of the support platform 2. The transmission process is stable and reliable, ensuring the precise swing of the support platform 2 and allowing the support platform 2 to remain stably at the target position.

[0027] In one embodiment, please refer to Figure 2 and Figure 3 The support platform 2 is equipped with a rotating component 21, which is rotatably mounted on the body 1. One end of the rotating component 21 is connected to the support platform 2, and the other end of the rotating component 21 has a driven gear 211, which meshes with the transmission belt 43. In this embodiment, by engaging the driven gear 211 with the transmission belt 43, the rotating component 21 can drive the support platform 2 to swing left and right. Its structure is simple, its transmission efficiency is high, and it can meet the precise swinging requirements of the support platform 2. In addition, the engagement of the driven gear 211 with the transmission belt 43 allows the transmission belt 43 to drive the driven gear 211 to rotate and then keep the driven gear 211 in its current position, so that the support platform 2 can be stably kept in its current position.

[0028] In one embodiment, please refer to Figure 2The support platform 2 includes a placement platform 22 and a first limiting member 23. The first limiting member 23 is slidably connected to the placement platform 22 and can adjust the space for fixing the steering gear under test when sliding. In this embodiment, by sliding the first limiting member 23, the space for fixing the steering gear under test can be flexibly adjusted according to the size of the steering gear under test, thereby achieving the fixing of steering gears under test of different sizes and improving the versatility of the testing device.

[0029] Further, please refer to Figure 2 The support platform 2 also includes a second limiting member 24, which is slidably connected to the placement platform 22. A clamping space for holding the steering gear under test is formed between the second limiting member 24 and the first limiting member 23. This embodiment adds a second limiting member 24 to the first limiting member 23. Through the cooperative use of the first limiting member 23 and the second limiting member 24, the steering gear under test can be clamped and fixed from two directions, providing more operational options for the clamping space and making it more convenient to use.

[0030] In one embodiment, please refer to Figure 2 The support platform 2 also includes a tensioning member 25 disposed on the first limiting member 23. The tensioning member 25 is threadedly connected to the first limiting member 23 and can abut against or disengage from the support platform 22 during rotation. In this embodiment, by rotating the tensioning member 25, the first limiting member 23 can be fixed or loosened. Thus, after adjusting the first limiting member 23 to slide to the target position, it can be firmly fixed on the placement platform 22 by the tensioning member 25, ensuring the stability of the clamping space and further improving the fixing effect of the steering gear under test.

[0031] In one embodiment, please refer to Figure 2 The steering gear sealing test device also includes a steering adjustment mechanism 5, which includes a connecting rod 51, a moving block 52, and a motor 53. The motor 53 is connected to the steering shaft 3 and drives the steering shaft 3 to rotate. The two ends of the connecting rod 51 are respectively connected to the motor 53 and the moving block 52, and the moving block 52 is slidably connected to the body 1. In this embodiment, the motor 53 can drive the steering shaft 3 to rotate, so that after the steering shaft 3 is connected to the steering gear under test, it can drive the steering gear to rotate, simulating the real working state of the car steering gear, thereby obtaining the water tightness of the steering gear when it is working in real time. The steering adjustment mechanism 5 also includes a slide rail 54 and a lead screw handle 55 provided on the slide plate 131. The moving block 52 is slidably connected to the slide rail 54. When the moving block 52 slides back and forth along the slide rail 54, it can adjust the position of the steering shaft 3, so that the steering shaft 3 can be more easily connected to the interface of the steering gear under test. The lead screw handle 55 is rotatably mounted on the slide plate 131 and threaded through the moving block 52. When the lead screw handle 55 rotates, it can drive the moving block 52 to slide back and forth through the thread, thereby precisely adjusting the position of the steering shaft 3.

[0032] In one embodiment, please refer to Figure 2 The bottom of the body 1 is equipped with casters 14 and a drain pipe 15. In this embodiment, by providing casters 14 at the bottom of the body 1, the entire device is easy to move and transport, improving the portability of the device; the drain pipe 15 facilitates the drainage of water from the water tank 11 after the test, making it convenient for cleaning and maintenance of the device.

[0033] To better understand this utility model, the following is combined with... Figures 1 to 4 The technical solution of this utility model is described in detail below: The steering gear sealing test device provided by this utility model includes a support platform 2 for placing the steering gear under test. Since the support platform 2 is rotatably mounted on the body 1, after the steering gear under test is placed and fixed on the support platform 2, the support platform 2 can be driven to rotate according to the required connection angle, so that the inclined interface of the steering gear under test is aligned with the steering shaft, thereby completing the connection between the steering shaft 3 and the steering gear under test. After the connection is completed, the steering shaft 3 can rotate to simulate the actual working state of a car. Water is then added to the water tank until it submerges the connection between the steering gear under test and the steering shaft 3. The water tightness of the steering gear under test is determined by observing whether there are air bubbles in the water. It can be seen that this application, by rotating the support platform 2, allows the steering shaft 3 to adapt to the connection of various steering gears with different inclined interfaces, further improving the compatibility of the test.
