Description

Technical Field

[0001] This utility model relates to the field of bearing press-fit testing technology, specifically to a wheel hub bearing unit press-fit testing device. Background Technology

[0002] Wheel hub bearing units are critical safety components of modern automotive chassis systems. They not only bear the entire weight of the vehicle body but also directly affect the vehicle's driving stability, braking safety, and fuel economy. Their press-fit quality—that is, the quality of the interference fit between the wheel hub bearing and components such as the steering knuckle and wheel hub—directly determines the overall performance and driving safety of the vehicle.

[0003] Traditional press-fitting equipment lacks effective clamping and positioning of the wheel hub, making it prone to movement during pressing. This causes misalignment between the bearing and the inner ring of the hub, resulting in installation misalignment and severely impacting press-fitting efficiency and alignment. Existing processes use pressure plates to quickly press the bearing in, but cannot monitor the pressing force in real time. When the bearing becomes stuck due to misalignment or interference, the system cannot provide a warning and can only forcibly increase the pressure to complete the pressing. This over-pressure assembly easily damages the bearing and wheel hub, not only compromising installation quality but also creating potential safety hazards for vehicles.

[0004] To address this, a hub bearing unit press-fit testing device is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a wheel hub bearing unit press-fit testing device to solve the problem mentioned in the background art where the testing device is prone to shaking under bumpy conditions, leading to inaccurate test values. To solve the above technical problem, this utility model is achieved through the following technical solution: This utility model is a wheel hub bearing unit press-fit testing device, comprising: The base plate, clamping assembly, and pressing assembly are provided. A fixed frame is fixedly connected above the base plate, and a horizontal plate is fixedly connected inside the fixed frame. A hub body is provided between the clamping assemblies, and a bearing body installed inside the hub body is provided inside the hub body. The clamping assembly is positioned above the clamping assembly; The clamping assembly includes: multiple transverse grooves, multiple sliders, two clamping plates, and two inclined grooves; Multiple transverse grooves are provided above the base plate; The multiple sliders are embedded and slidably connected to the interior of the multiple transverse grooves; The two clamps are fixedly connected to the tops of the multiple sliders; Multiple inclined slots are formed on opposite sides of the two clamping plates; The clamping assembly includes: a first electric push rod, two vertical rods, two limiting discs, and a connecting plate; The first electric push rod is fixedly connected to the top of the horizontal plate, and the output end of the first electric push rod extends through to the bottom of the horizontal plate; The two vertical rods are slidably connected to the interior of the horizontal plate and extend to both sides; The two defined discs are fixedly connected to the tops of the two vertical rods; The connecting plate is fixedly connected to the end away from the two limiting discs, and the connecting plate is fixedly connected to the output end of the first electric push rod. A pressure plate is provided below the connecting plate, and two elastic pads are fixedly connected between the pressure plate and the connecting plate. A pressure module is provided between the two elastic pads.

[0006] Preferably, a display control screen is fixedly installed between the fixed frame and the horizontal plate, and the display control screen is electrically connected to the pressure module via wires.

[0007] Preferably, the clamping assembly further includes: a side plate, a second electric push rod, a trapezoidal block, and two inclined blocks; The side plate is fixedly connected to the top of the base plate; The second electric push rod is fixedly installed on the outside of the side plate, and the output end of the second electric push rod extends through to the outside of the side plate; The trapezoidal block is fixedly connected to the output end of the second electric push rod; The two inclined blocks are positioned on either side of the trapezoidal block.

[0008] Preferably, it further includes a connecting assembly, which includes two connecting blocks, two through slots, and two connecting brackets; The two through slots are formed through the outer sides of the two base plates, and the two through slots are connected to the multiple transverse slots; The two connecting blocks are slidably installed inside the two through slots, and the two connecting blocks are fixedly connected to the bottom of the multiple sliders; The two connecting brackets are fixedly connected to the top of the two connecting blocks, and the other end of the two connecting brackets is fixedly connected to the two inclined blocks.

[0009] Preferably, each of the two inclined blocks has a limiting groove on one side opposite to the other, and both sides of the trapezoidal block are fixedly connected with protrusions, with one end of each protrusion being inserted into and slidably connected to the two limiting grooves.

[0010] Preferably, support columns are fixedly installed around the bottom of the base plate.

[0011] Preferably, soft pads are fixedly installed inside both of the inclined grooves.

[0012] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects: First, through the clamping assembly and connecting assembly, the trapezoidal block is moved by the first electric push rod. After the trapezoidal block moves, the inclined blocks on both sides move in opposite directions. Combined with the connecting frame, the connecting block inside the through groove moves. After the connecting block moves, the slider slides inside the transverse groove, facilitating relative movement of the clamping plate. Under the action of the inclined groove, different specifications of wheel hubs are clamped and fixed, ensuring coaxiality between the wheel hub and the bearing, avoiding misalignment, and improving the work efficiency during bearing installation. Second, by setting up a pressing assembly, elastic pad, pressure module, and display control screen, the pressure plate performs a pressing operation during bearing installation. The pressure module monitors the pressure changes in real time during the pressing process. Once the bearing interferes with the seat hole, the pressure value will rise abnormally and be immediately fed back to the display control screen. This structure effectively solves the technical problem of difficulty in real-time pressure monitoring during wheel hub bearing installation, ensuring controllable installation quality and eliminating potential hazards caused by poor assembly.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0018] Please see Figures 1-5 As shown, this utility model relates to a wheel hub bearing unit press-fit testing device, including: a base plate 2, a clamping assembly 15 and a pressing assembly 11. A fixing frame 1 is fixedly connected above the base plate 2, and a horizontal plate 3 is fixedly connected inside the fixing frame 1. A wheel hub body 9 is arranged between the clamping assemblies 15. A bearing body 10 is installed inside the wheel hub body 9. By installing the bearing body 10 inside the wheel hub body 9, it can be ensured that the wheel hub body 9 rotates more smoothly. The clamping assembly 11 is positioned above the clamping assembly 15; The clamping assembly 15 includes: multiple transverse grooves 5, multiple sliders 6, two clamping plates 4 and two inclined grooves 8; Multiple transverse grooves 5 are provided above the base plate 2; Multiple sliders 6 are embedded and slidably connected to multiple transverse grooves 5, which facilitates the stable sliding of sliders 6 within the transverse grooves 5; Two clamping plates 4 are fixedly connected to the top of multiple sliders 6. The clamping plates 4 can be driven to move stably by moving the sliders 6. Multiple inclined grooves 8 are opened on the opposite side of the two clamping plates 4. The inclined grooves 8 can be used to clamp and fix the wheel hub body 9 of different specifications. The clamping assembly 15 also includes: a side plate 152, a second electric push rod 151, a trapezoidal block 153, and two inclined blocks 154; Side plate 152 is fixedly connected to the top of base plate 2; The second electric push rod 151 is fixedly installed on the outside of the side plate 152, and the output end of the second electric push rod 151 extends through to the outside of the side plate 152. The trapezoidal block 153 is fixedly connected to the output end of the second electric push rod 151. The trapezoidal block 153 can be moved under the drive of the second electric push rod 151. Two inclined blocks 154 are positioned on both sides of the trapezoidal block 153; It also includes a connecting component, which includes two connecting blocks 71, two through slots 7 and two connecting brackets 16; Two through slots 7 are opened through the outer sides of the two base plates 2, and the two through slots 7 are connected to multiple transverse slots 5; Two connecting blocks 71 are slidably installed inside two through slots 7, and the two connecting blocks 71 are fixedly connected to the bottom of multiple sliders 6. The two sliders 6 can be moved by driving the two connecting blocks 71. Two connecting brackets 16 are fixedly connected to the top of two connecting blocks 71, and the other end of the two connecting brackets 16 is fixedly connected to two inclined blocks 154. The connecting brackets 16 can be moved by the inclined blocks 154, and the moving of the connecting brackets 16 can drive the connecting blocks 71 to move inside the through groove 7. Each of the two inclined blocks 154 has a limiting groove 155 on one side opposite to the other. Both sides of the trapezoidal block 153 are fixedly connected with protrusions. One end of each protrusion is inserted into and slidably connected to the inside of the two limiting grooves 155. By sliding the protrusions inside the limiting grooves 155, the position of the two inclined blocks 154 can be moved under the driving action of the trapezoidal block 153.

[0019] Working principle: First, the hub body 9 is installed on the base plate 2 and positioned between two inclined slots 8. The second electric push rod 151 is controlled by the display control screen 12. The second electric push rod 151 drives the trapezoidal block 153 to move. When the trapezoidal block 153 moves, it slides inside the limiting slot 155 through the protrusion, which can realize the relative driving of the two inclined blocks 154. The two inclined blocks 154 drive the connecting frame 16 to move. After the connecting frame 16 moves, it drives the connecting block 71 to move. The connecting block 71 slides inside the through slot 7, which can slide the slider 6 inside the transverse slot 5, so that the slider 6 drives the clamping plate 4 to move. The hub body 9 can be clamped and fixed through the inclined slots 8 set on the clamping plate 4.

[0020] This solution addresses the problem of not being able to clamp and fix wheel hubs of different specifications by using the clamping component 15 and the connecting component.

[0021] Please see Figure 1 and Figure 4 As shown, this embodiment is based on the above embodiment, and the pressing assembly 11 includes: a first electric push rod 111, two vertical rods 113, two limiting discs 112 and a connecting plate 114; The first electric push rod 111 is fixedly connected to the top of the horizontal plate 3, and the output end of the first electric push rod 111 extends through to the bottom of the horizontal plate 3; Two vertical rods 113 are slidably connected to the inside of the horizontal plate 3 and extend to both sides, so that the vertical rods 113 can slide stably inside the horizontal plate 3; Two limiting discs 112 are fixedly connected to the top of two vertical rods 113 to ensure that the connecting rods slide and limit their movement. The connecting plate 114 is fixedly connected to the end away from the two limiting disks 112. The connecting plate 114 is fixedly connected to the output end of the first electric push rod 111. The connecting plate 114 can be moved under the drive of the first electric push rod 111. A clamping plate 17 is provided below the connecting plate 114. Two elastic pads 13 are fixedly connected between the clamping plate 17 and the connecting plate 114. A pressure module 14 is provided between the two elastic pads 13. By setting the pressure module 14 and the elastic pads 13, pressure detection can be performed after the clamping plate 17 is pressed down. A display control screen 12 is fixedly installed between the fixed frame 1 and the horizontal plate 3. The display control screen 12 is electrically connected to the pressure module 14 through wires. The display control screen 12 can display the pressure changes detected by the pressure module 14. The display control screen 12 uses an STM32 microcontroller. The input and output pins of the microcontroller are connected to the first electric push rod 111, the second electric push rod 151 and the pressure module 14 as described above. This can be achieved by programming the microcontroller. The circuit and program used are common technologies in the field of microcontrollers. Those skilled in the art can easily derive the specific circuit based on the above control relationship description. Therefore, the specific circuit will not be described in detail in this article. Support columns 201 are fixedly installed around the bottom of the base plate 2. The support columns 201 can provide stable support for the detection device. Both inclined grooves 8 are fixedly installed with soft pads 81. The soft pads 81 can protect the wheel hub body 9 when it is clamped.

[0022] Working principle: When the bearing body 10 is pressed into the wheel hub body 9, the first electric push rod 111 is controlled by the display control screen 12. The first electric push rod 111 pushes the connecting plate 114 to move. After the connecting plate 114 moves, it drives the pressing plate 17 to move, so that the pressing plate 17 contacts the bearing body 10 and presses it into the wheel hub body 9. At the same time, the pressure generated by the pressing plate 17 is transmitted to the pressure module 14 and displayed on the display control screen 12. Once the bearing body 10 interferes with the seat hole, the pressure value will rise abnormally and be immediately fed back to the display control screen 12. This structure effectively solves the technical problem of difficulty in real-time monitoring of pressure during wheel hub bearing installation, ensures controllable installation quality, and eliminates potential hazards caused by poor assembly.

[0023] This solution addresses the technical challenge of real-time pressure monitoring during wheel hub bearing installation by using a clamping assembly 11 and a pressure module 14.
