[0025] Example

[0026] Reference Figure 1-5 This embodiment of the present invention provides a docking device for the middle section of an axle housing and an axle head, comprising:

[0027] The operating mechanism 100 includes a mounting plate 101, a fixing block 102 fixedly connected to the surface of the mounting plate 101, a drive motor 103 adapted to be installed on the side wall of the fixing block 102, a lead screw 104 fixedly installed at the output end of the drive motor 103, a slider 105 fixedly connected to the side surface of the fixing block 102, a clamping plate 108 used in conjunction with the slider 105, and a clamping assembly 109 disposed in the inner cavity of the clamping plate 108.

[0028] The auxiliary mechanism 200 includes a connecting block 201 fixedly connected to the side surface of the mounting plate 101, a groove 202 formed on the surface of the connecting block 201, a damping component 203 laid in the center of the groove 202, a protective sleeve 204 slidably connected to the center of the groove 202, and a moving block 205 fixedly connected to the bottom of the protective sleeve 204.

[0029] The operating mechanism 100 also includes a sliding sleeve 106 slidably connected to the side surface of the slider 105, a fixing plate 107 fixedly connected to the side surface of the sliding sleeve 106, and a clamping plate 108 snapped into the side wall of the fixing plate 107.

[0030] Two sets of sliding sleeve 106, fixing plate 107, clamping plate 108 and clamping assembly 109 are provided, and the two sets of structures are used in conjunction.

[0031] Specifically, the drive motor 103 is started to rotate the lead screw 104, which pushes the slider 105 to move along the fixed block 102. The slider 105 drives the sliding sleeves 106 on both sides to move synchronously, so that the clamping plate 108 moves closer to the center. The spring 109d buffer mechanism in the clamping assembly 109 adaptively adjusts the position of the clamping block 109e to accurately clamp the middle section of the bridge housing. At the same time, the protective sleeve 204 of the auxiliary mechanism 200 moves along the slide groove 202 under the buffer of the damping assembly 203 to ensure smooth docking of the shaft head. When the bridge housing and the shaft head approach each other, the damping plate 203a absorbs the residual impact. The two sets of symmetrical clamping assemblies 109 work together to complete the precise alignment, and finally achieve the non-damaging and precise docking of the bridge housing and the shaft head, effectively ensuring the assembly accuracy and the safety of the parts.

[0032] The clamping assembly 109 includes a stop bar 109a, a fixing rod 109b fixedly connected to the side surface of the stop bar 109a, a push plate 109c sleeved on the outer surface of the fixing rod 109b, a spring 109d sleeved on the side surface of the fixing rod 109b, and a clamping block 109e fixedly installed at the end of the fixing rod 109b.

[0033] The side surface of the stop bar 109a is provided with two sets of fixing rods 109b and two sets of springs 109d, and the two sets of structures are used in conjunction.

[0034] The damping assembly 203 includes a damping plate 203a, a partition plate 203b fixedly connected to the inner cavity of the damping plate 203a, and a through hole 203c formed on the surface of the partition plate 203b.

[0035] The damping plate 203a is a hollow soft plate, and the damping plate 203a is in contact with the moving block 205.

[0036] It should be noted that when the drive motor 103 starts, the lead screw 104 drives the slider 105 to move, causing the two sets of symmetrically arranged clamping components 109 to move synchronously; the fixed rod 109b, under the buffering effect of the spring 109d, pushes the clamping block 109e to adaptively adjust the clamping force, ensuring that the bridge housing is firmly clamped without damaging the surface; at the same time, the protective sleeve 204 drives the moving block 205 to move in the slide groove 202, and the hollow damping plate 203a absorbs the docking impact through the buffering effect of the through hole 203c of the partition 203b; when the bridge housing approaches the shaft head, the flexible contact between the damping plate 203a and the moving block 205 further reduces the impact force, and the clamping block 109e buffered by the two sets of springs 109d achieves precise alignment, finally completing the non-destructive precision docking of the bridge housing and the shaft head. Through the perfect combination of mechanical linkage and buffering design, high-precision automated assembly is achieved.

[0037] In use, the drive motor 103 drives the lead screw 104 transmission system to achieve precise displacement control, so that the two symmetrically distributed clamping components 109 move synchronously. The clamping mechanism uses the spring 109d buffer system and the adaptive clamping block 109e in combination to ensure clamping force while avoiding damage to the surface of the parts. The damping component 203 of the auxiliary mechanism 200 effectively absorbs the impact energy during the docking process through the combination design of the hollow damping plate 203a and the partition plate 203b with through holes 203c. Through mechanical linkage and intelligent buffering mechanism, automatic alignment and non-destructive assembly of the bridge housing and shaft head are achieved. Its symmetrical structural design ensures balanced force and improves assembly accuracy and working reliability.

[0038] In summary, the use of dual motors and lead screw 104 achieves millimeter-level docking accuracy, significantly improving assembly quality. The symmetrical clamping mechanism, combined with the spring 109d buffer design, ensures secure clamping while effectively protecting the surface integrity of components. The intelligent damping system, through the combination of hollow damping plate 203a and through-hole partition 203b, can absorb a large amount of impact energy. The combined use of these structures allows the equipment to adapt to the assembly requirements of different bridge housing specifications, making operation simple and efficient. The overall structure operates smoothly and reliably, improving the efficiency of traditional manual assembly and reducing labor intensity and production costs.
