Description
Technical Field
[0001] This utility model relates to the field of differential lock assembly, specifically to an automatic alignment and pressing device for a baffle plate. Background Technology
[0002] The differential lock assembly is a crucial component of a vehicle's drive system. Typically mounted on the differential, it locks the differential under specific conditions to enhance the vehicle's traction on rough roads or off-road terrain. The baffles within the differential lock assembly generally serve to limit, secure, and ensure the proper functioning of internal components, such as preventing accidental disengagement of parts like the sliding sleeve or solenoid coil.
[0003] In the production process, it is usually difficult to achieve perfect concentricity when pressing baffles using traditional presses. On the one hand, the mechanical structure of traditional presses has certain precision limitations and may be affected by external environmental interference, which can disrupt the concentricity between the press and the baffles. On the other hand, the operation of placing baffles and adjusting the press center varies depending on the operator's operating habits and proficiency. At the same time, operators usually rely on visual inspection and experience to judge the centering status, which makes it difficult to achieve absolute precision. Ultimately, this results in the press and the baffles not being completely concentric. Utility Model Content

[0022] See Figures 1 to 3This utility model provides an automatic alignment and pressing device for baffles, including a mounting shell 1, a top-pressing floating mechanism fixedly disposed in the inner cavity of the mounting shell 1, and multiple spring adjusting mechanisms 2 fixedly disposed on the outer circumferential surface of the mounting shell 1. Preferably, a portion of the top-pressing floating mechanism near its top end is located in the inner cavity of the mounting shell 1, and another portion extends out of the inner cavity of the outer shell. The top-pressing floating mechanism includes a mounting sleeve 3, a top-pressing structure 4, and a floating structure 5. The top-pressing structure 4 includes a top rod 401, a top point 402, a spring spacer 403, and a first spring 404. The mounting sleeve 3 is fixedly disposed in the inner cavity of the mounting shell 1, and the mounting sleeve... A spring plate 301 is fixedly installed at the top of the mounting sleeve 3, and a limiting groove 302 is provided at the bottom. An inlet / outlet through hole is provided on the spring plate 301, and a limiting plate 303 is installed in the limiting groove 302. A limiting through hole is provided on the limiting plate 303. A push rod 401 is installed in the inner cavity of the mounting sleeve 3, with its top end passing through the inlet / outlet through hole and its bottom end fixedly connected to the top end of the tip 402. The top end of the tip 402 passes through the limiting through hole, and a limiting component is provided on the tip 402. The limiting component is located above the limiting plate 303. Specifically, the bottom end of the tip 402 is cone-shaped for easy centering and to avoid repeated adjustments. The spring spacer 403 and the first spring 404 are both fitted onto the push rod 401. The top end of the spring spacer 403 is fixedly connected to the spring circular plate 301, and the bottom end is fixedly connected to the top end of the first spring 404. The bottom end of the first spring 404 is fixedly connected to the top end of the tip 402. Preferably, the center of the spring circular plate 301, the center of the inlet / outlet through hole, the axis of the push rod 401, the center of the limiting circular plate 303, the center of the limiting through hole, and the axis of the tip 402 are all located on the same plumb line. The floating structure 5 includes a second spring 501, a floating pressure sleeve 502, and a pressure head 503 for pressing the baffle. The second spring 501 is fitted onto the spring spacer 401. On sleeve 403, floating pressure sleeve 502 is fitted on first spring 404 and passes through limiting through hole. The top end of second spring 501 is fixedly connected to spring round plate 301, and the bottom end is fixedly connected to the top end of floating pressure sleeve 502. The bottom end of floating pressure sleeve 502 is fixedly connected to the top end of pressure head 503. Pressure head 503 has an inner cavity for accommodating baffle. Top tip 402 is located in the inner cavity of pressure head 503, and the bottom end of top tip 402 extends out of the inner cavity of pressure head 503. Preferably, the axis of top tip 402 and the axis of inner cavity of pressure head 503 are both located on the same plumb line. During the pressing process, it can further ensure that top tip 402 and baffle are concentric.Multiple mounting holes are evenly arranged circumferentially on the outer peripheral surface of the mounting housing 1. Multiple spring adjustment mechanisms 2 are respectively disposed in the multiple mounting holes. Each spring adjustment mechanism 2 includes a connecting housing, a compression spring, and a ball head. The compression spring is disposed in the inner cavity of the connecting housing, with one end fixedly connected to the inner cavity of the connecting housing and the other end fixedly connected to the ball head. The ball head extends out of the connecting housing and abuts against the mounting sleeve 3. In other embodiments, a ball head plunger may also be provided in the mounting hole.
[0023] The basic working principle of the automatic alignment and pressing device for baffle plates involved in this utility model is as follows: By setting up the mounting housing 1, the spring adjustment mechanism 2 can be easily installed, and the top-pressure floating mechanism can be protected. By setting up the top-pressure floating mechanism and the spring adjustment mechanism 2, during use, the bottom end of the tip 402 can contact the baffle plate first. Specifically, when the tip 402 is not concentric with the baffle plate, that is, when the tip 402, the push rod 401, the mounting sleeve 3, etc., are offset relative to the mounting housing 1, the axis of the tip 402 is inclined. In the non-plumb state, the ball head of the spring adjusting mechanism 2 on the inclined direction of the tip 402 will retract into the inner cavity of the connecting housing. Under the action of the compression spring, the ball head can be pushed to reset, thereby automatically resetting the axis of the tip 402 to the plumb state, that is, moving the tip 402 towards the center of the baffle, thus ensuring automatic alignment. After alignment, by continuously applying downward pressure to the automatic alignment press-fitting device, the baffle can push the push rod 401 and the tip 402 upward in the opposite direction. At this time, the push rod 401 can pass through the spring. The through holes on the circular plate 301 move upward, allowing the tip 402 to move upward relative to the floating pressure sleeve 502. The tip 402 and the spring spacer 403 compress the first spring 404, causing the first spring 404 to be in an elastic energy storage state. When the bottom end of the tip 402 moves upward into the inner cavity of the pressure head 503, the baffle can also enter the inner cavity of the pressure head 503 and be fixed in the inner cavity of the pressure head 503. By continuously applying downward pressure to the automatic alignment and pressing device, the baffle can push the pressure head 503 and the limiting circular plate 301 in the opposite direction. 03. The floating pressure sleeve 502 moves upward. At this time, the floating pressure sleeve 502 can move upward through the limiting through hole on the limiting circular plate 303. The floating pressure sleeve 502 and the spring circular plate 301 compress the second spring 501, so that the second spring 501 is in an elastic energy storage state. The downward pressure is continuously applied to the automatic alignment pressing device until the baffle is pressed. After the pressing is completed, the downward pressure is stopped on the automatic alignment pressing device. Under the action of the first spring 404 and the second spring 501, the tip 402 and the pressure head 503 can be reset respectively.
[0024] See Figures 1 to 3 The present invention will be further described below with reference to a specific embodiment:

The two round nuts 603 are both located above the first bearing 601 and are arranged adjacent to each other. The locking washer 604 is located between the round nuts 603 and the first bearing 601. The second bearing 602, two round nuts 603, and a locking washer 604 are all fitted onto the outer circumference of the mounting sleeve 3 of the top-pressure floating mechanism. By setting the first bearing 601 and the second bearing 602, the radial runout and axial movement of the top-pressure floating mechanism can be restricted. By setting the two round nuts 603 and the locking washer 604, the axial displacement of the first bearing 601, the second bearing 602, and the top-pressure floating mechanism can be restricted, thus achieving locking. At the same time, the two round nuts 603 can also resist vibration and impact, preventing loosening.
[0027] In this embodiment, see Figure 1 , Figure 2 As a preferred design, the top-pressing structure 4 also includes a fastening bolt 405 and a washer 406. The fastening bolt 405 is screwed to the top of the push rod 401, and the washer 406 is fitted on the fastening bolt 405 and located between the fastening bolt 405 and the push rod 401. The fastening bolt 405 has high connection strength, stable and reliable force transmission, and flexible assembly with high assembly fault tolerance. The washer 406 can increase friction, prevent the fastening bolt 405 from loosening, and protect the contact surface between the push rod 401 and the fastening bolt 405.
[0028] In this embodiment, see Figure 1As a preferred design, the top pressing structure 4 also includes a retaining spring 407. The retaining spring 407 is fitted on the top rod 401 and is away from the bottom end of the top rod 401. By setting the retaining spring 407, the axial movement of the top rod 401 can be further prevented, and it plays the role of axial positioning and fixing.
[0029] In this embodiment, see Figure 1 , Figure 2 As a preferred design, the limiting component is fixedly installed at the top of the tip 402, and the bottom end of the first spring 404 is fixedly connected to the limiting component. The limiting component can restrict the tip 402 from sliding down out of the limiting circular plate 303.
[0030] As can be seen from the above, the automatic alignment and pressing device for baffles of this utility model has the following beneficial effects:

The structure is simple, the cost is low, and it can be applied to the pressing of baffle plates in different types of differential lock assemblies.
