Description

Technical Field

[0001] This utility model relates to the field of axle housing fixing equipment, and in particular to a special centering clamping device for axle housings. Background Technology

[0002] The axle housing (or simply axle housing) is a core structural component of the automotive drive axle. It primarily supports and protects the internal transmission system (such as the final drive, differential, and half-shafts) and bears the weight of the vehicle and the transmission of road reaction forces. It is a crucial component of the vehicle's driving and transmission systems, and is essential for the vehicle's stability, power transmission efficiency, and safety.

[0003] The axle housings of different vehicle models have different structures, requiring various processing steps, and the stability of the axle housings must be maintained during the processing.

[0004] Regarding the aforementioned technologies, existing fixing equipment can fix the axle housing to the worktable, but it cannot accurately locate its center position, thus affecting the accuracy of subsequent processing. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a special centering clamping device for axle housings.

[0006] This utility model provides a special centering and clamping device for axle housings, which adopts the following technical solution:

[0007] A special centering and clamping device for axle housing includes a worktable on which an axle housing is placed. The axle housing includes a semi-circular hollow hemisphere and connecting rods connecting the two ends of the hemisphere. The two connecting rods are arranged opposite to each other. A fixed seat is provided below the hemisphere. A telescopic rod is vertically provided at the center of the fixed seat. A fixing component for positioning the hemisphere is provided inside the fixed seat.

[0008] By adopting the above technical solution, when it is necessary to fix the axle housing at the center, the worker places the axle housing on the workbench, aligns the center of the hollow hemisphere with the bottom of the telescopic rod, and then activates the fixing component to fix the axle housing. This achieves the function of locating the center position of the axle housing, which is easy to understand and helps to improve work efficiency.

[0009] Optionally, the fixing component includes four drive screws, and the upper end face of the fixing base has four sliding grooves, which are opened in pairs opposite each other. The drive screws are correspondingly set in the sliding grooves, and sliders are installed in the sliding grooves. The sliders are slidably connected to the sliding grooves and are threadedly connected to the drive screws. A rotating motor is provided below the fixing base. The output shaft of the rotating motor passes through the fixing base and is coaxially fixedly connected to a rotating wheel. The end of each drive screw near the telescopic rod is coaxially fixedly connected to a driven wheel, and the rotating wheel meshes with all four driven wheels.

[0010] By adopting the above technical solution, when the axle housing needs to be fixed by fasteners, the operator starts the rotating motor, which drives the rotating wheel to rotate, thereby driving the four drive screws to rotate, which in turn drives the four sliders to move along the sliding groove, so that the sliders extend out of the fixing seat, thereby clamping the hemisphere and fixing the axle housing. This is convenient to operate and helps to improve work efficiency.

[0011] Optionally, the workbench is provided with support frames at both ends, and a lifting cylinder is provided on the upper end face of the support frame. The piston rod of the lifting cylinder passes through the support frame and is fixedly connected to a pressure plate, which is horizontally set.

[0012] By adopting the above technical solution, when it is necessary to further fix the position of the axle housing, the staff will activate the lifting cylinder. The lifting cylinder will press the two ends of the axle housing downwards to further fix the position of the axle housing and ensure its fixing effect.

[0013] Optionally, the slider is fixedly connected to two sides with locking blocks, and the sliding groove of the fixed seat is connected to two slots on both sides. When the slider is located in the sliding groove, the locking blocks are located in the slots.

[0014] By adopting the above technical solution, the movement of the slider is made more stable through the cooperation of the card block and the card slot, which helps to improve the stability of the device.

[0015] Optionally, the end of the slider away from the telescopic rod is provided with several protrusions, which are evenly distributed.

[0016] By adopting the above technical solution, when the axle housing needs to be fixed, the slider will press against the inside of the hemisphere, thereby making the protrusion contact the hemisphere, increasing its friction and improving its fixing effect.

[0017] In summary, this utility model has at least one of the following beneficial technical effects:

[0018] 1. By setting up a workbench, hemisphere, connecting rod, fixed seat, telescopic rod and fastener, when it is necessary to fix the axle housing at the center, the worker places the axle housing on the workbench, aligns the center of the hollow hemisphere with the bottom of the telescopic rod, and then activates the fastener to fix the axle housing. This realizes the function of locating the center position of the axle housing, which is easy to understand and helps to improve work efficiency.

[0019] 2. By setting protrusions, when the axle housing needs to be fixed, the slider will press against the inside of the hemisphere, thereby making the protrusions contact the hemisphere, increasing its friction and improving its fixing effect. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to all the accompanying drawings.

[0025] This utility model discloses a special centering clamping device for vehicle axle housings.

[0026] Reference Figure 1 , Figure 2 and Figure 3 A special centering and clamping device for axle housings includes a worktable 1 and a fixing member 2. An axle housing 10 is placed on the worktable 1. The axle housing 10 includes a semi-circular hollow hemisphere 101 and connecting rods 102 connecting both ends of the hemisphere 101. The two connecting rods 102 are arranged opposite to each other. The fixing member 2 is disposed on the worktable 1 and connected to the worktable 1. The worktable 1 supports the operation of the device, and the fixing member 2 ensures the stability of the axle housing 10 on the worktable 1.

[0027] Reference Figure 1 , Figure 2 and Figure 3The fixing component 2 includes four drive screws 21. A fixing seat 22 is provided below the hemisphere 101. A telescopic rod 23 is vertically provided at the center of the fixing seat 22. Four sliding grooves 24 are provided on the upper end surface of the fixing seat 22. The sliding grooves 24 are opened in pairs opposite each other. The drive screws 21 are correspondingly arranged in the sliding grooves 24. A slider 25 is installed in the sliding groove 24. The slider 25 is slidably connected to the sliding groove 24. The slider 25 is threadedly connected to the drive screws 21. A rotating motor 26 is provided below the fixing seat 22. The output shaft of the rotating motor 26 passes through the fixing seat 22 and is coaxially fixedly connected to a rotating wheel 27. A driven wheel 28 is coaxially fixedly connected to the end of each drive screw 21 near the telescopic rod 23. The rotating wheel 27 meshes with all four driven wheels 28.

[0028] Reference Figure 1 , Figure 2 and Figure 3 When it is necessary to fix the axle housing 10 at the center, the operator places the axle housing 10 on the workbench 1 and aligns the center of the hollow hemisphere 101 with the lower part of the telescopic rod 23, thereby adjusting the telescopic rod 23 to align with the center of the hemisphere 101. Then, the rotating motor 26 is started, which drives the rotating wheel 27 to rotate, thereby driving the four drive screws 21 to rotate, which in turn drives the four sliders 25 to move along the sliding groove 24, so that the sliders 25 extend out of the fixing seat 22, thereby clamping the hemisphere 101 and fixing the axle housing 10. This is convenient to operate and helps to improve work efficiency.

[0029] Reference Figure 1 , Figure 2 and Figure 3 The slider 25 is fixedly connected to two sides with locking blocks. The sliding groove 24 of the fixed base 22 is connected to two slots on both sides. When the slider 25 is located in the sliding groove 24, the locking blocks are located in the slots. Several protrusions 251 are evenly distributed at the end of the slider 25 away from the telescopic rod 23. The cooperation of the locking blocks and slots makes the movement of the slider 25 more stable, which helps improve the stability of the device. When the axle housing 10 needs to be fixed, the slider 25 will press against the inside of the hemisphere 101, thereby causing the protrusions 251 to contact the hemisphere 101, increasing its friction and improving its fixing effect.

[0030] Reference Figure 1 , Figure 2 and Figure 3The workbench 1 has support frames 11 at both ends. A lifting cylinder 12 is mounted on the upper surface of each support frame 11. The piston rod of the lifting cylinder 12 passes through the support frame 11 and is fixedly connected to a pressure plate 13, which is horizontally positioned. When further fixing the position of the axle housing 10 is required, the operator activates the lifting cylinder 12. The lifting cylinder 12 presses both ends of the axle housing 10 downwards, thereby further fixing the position of the axle housing 10 and ensuring its fixation effect.

[0031] The implementation principle of the special centering clamping device for axle housing in this embodiment of the utility model is as follows: When it is necessary to fix the axle housing 10 at the center, the operator places the axle housing 10 on the workbench 1 and aligns the center of the hollow hemisphere 101 with the lower part of the telescopic rod 23, thereby adjusting the telescopic rod 23 to align with the center of the hemisphere 101. Then, the rotating motor 26 is started, and the rotating motor 26 drives the rotating wheel 27 to rotate, thereby driving the four drive screws 21 to rotate, which in turn drives the four sliders 25 to move along the sliding groove 24, so that the sliders 25 extend out of the fixing seat 22, thereby clamping the hemisphere 101 and fixing the axle housing 10, which is convenient for operation.

[0032] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
