Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, specifically to a flipping device for the integrated flipping and transfer of brake discs and wheel hub bearings. Background Technology

[0002] In automotive braking system manufacturing, the assembly of brake discs and wheel bearings is one of the core chassis processes, and its precision directly affects braking performance, NVH performance, and driving safety. After the brake discs and wheel bearings are assembled, the splines of the drive shaft must be inserted into the spline holes of the wheel bearings, ensuring that the spline teeth are aligned to avoid misalignment that could lead to wear or abnormal noise. After installing the drive shaft fixing nuts, tighten them to the specified torque according to the vehicle model, and install dust covers or retaining rings to prevent dirt and sand from entering the spline holes. For integrated wheel bearing units, care must be taken to avoid bumping or contaminating the grease inside the wheel bearings during spline hole and spline installation.

[0003] like Figure 3 As shown, after the brake disc and wheel hub bearing are bolted together to form a single unit, the spline hole of the wheel hub bearing used for connecting to the shaft faces downwards, which affects the subsequent automotive chassis assembly process. The existing flipping process usually uses manual labor, but manual flipping is time-consuming, laborious, and inefficient. At the same time, the spline and spline hole need to be aligned during the installation process. During this process, the workers need to keep the position of the integrated brake disc, wheel hub bearing, and drive shaft relatively fixed. However, the workers cannot maintain this fixed position for a long time, which may cause physical harm and may cause damage to the spline or spline hole, affecting the transmission effect of the vehicle. Utility Model Content

[0004] This utility model addresses the problem of achieving precise and damage-free fit between the splined hole of the wheel hub bearing and the splined hole of the drive shaft after the brake disc and wheel hub bearing are screwed together as a single unit. It provides a flipping device for the integrated flipping and transfer of the brake disc and wheel hub bearing. The specific technical solution is as follows:

[0005] This utility model includes a mounting bracket, which is fixed in relative position to various devices used for assembling an automobile chassis; a movable component mounted on the mounting bracket, the movable component's movement trajectory being a vertical plane; and a flipping component mounted on the movable component, the axis of the flipping component coinciding with the axis of the brake disc, the flipping component being able to uniformly apply a horizontal pressure pointing towards the axis and a vertically upward supporting force to the side of the brake disc, the flipping component being able to drive the brake disc and wheel hub bearing to rotate relative to the movable component, and the movable component being able to drive the flipping component to move relative to the mounting bracket.

[0006] Preferably, the moving component includes: a rodless cylinder and a horizontal slide rail mounted on a mounting bracket, the length direction of the rodless cylinder and the horizontal slide rail being horizontal, and the mounting surface of the rodless cylinder and the horizontal slide rail being one side of the mounting bracket; a vertical cylinder and a vertical slide rail that move along the rodless cylinder, the movement direction of the vertical cylinder being the same as the length direction of the vertical slide rail, the vertical cylinder being able to drive the tilting component to move along the vertical slide rail, the vertical cylinder and the vertical slide rail being mounted on the same side of the rodless cylinder, the rodless cylinder being able to drive the vertical cylinder and the vertical slide rail to move horizontally; and limiting blocks mounted at both ends of the mounting bracket or the rodless cylinder or the horizontal slide rail, the limiting blocks at both ends forming the horizontal stroke of the vertical cylinder and the vertical slide rail.

[0007] Preferably, horizontal slide rails are arranged on both sides of the rodless cylinder; vertical slide rails are arranged on both sides of the vertical cylinder.

[0008] Preferably, the flipping assembly includes: a fixed plate disposed on the moving assembly, the bottom and top surfaces of the fixed plate being horizontal, and the moving assembly capable of driving the fixed plate to move along a vertical plane; at least two clamping arms disposed at both ends of the bottom surface of the fixed plate, the clamping arms being capable of moving towards or away from each other along the bottom surface of the fixed plate; rotating claws disposed on opposite sides of the clamping arms, the rotating claws being capable of rotating simultaneously relative to the sides of the clamping arms by the same angle; and limiting posts disposed at the ends of the clamping arms near the rotating claws, the limiting posts being located at both ends of the rotating claws, the side of the limiting posts away from the fixed plate forming the rotation stroke of the rotating claws.

[0009] Preferably, the maximum diameter of the brake disc is within the range of the maximum and minimum stroke of the clamping arm.

[0010] Preferably, the rotating claws are connected by a telescopic rod, the telescopic rod extending in the same direction as the clamping arm; and rollers are provided at both ends of the rotating claws that contact the brake disc, the axis of the rollers being parallel to the axis of the brake disc, and the side of the rollers being able to rotate freely relative to the side of the brake disc.

[0011] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0012] This invention features a movable component that moves and flips the component in a vertical plane, allowing it to approach and apply a uniform force to the side of the brake disc. This enables the movable component to move the brake disc and wheel hub bearing. Furthermore, the rotating mechanism of the flipping component reverses the vertical positions of the brake disc and wheel hub bearing, facilitating the subsequent spline assembly of the drive shaft and wheel hub bearing. The movable component also maintains the relative height of the wheel hub bearing to the drive shaft, ensuring that the spline angles of the drive shaft and the spline holes of the wheel hub bearing are the same before inserting the wheel hub bearing into the drive shaft. This improves assembly accuracy and prevents damage to the wheel hub bearing. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] like Figure 3 As shown, the brake disc 4 and the wheel hub bearing 5 are connected as one piece by bolts, and the diameter of the brake disc 4 is larger than the diameter of the wheel hub bearing 5.

[0020] like Figure 1 As shown, this embodiment includes a mounting bracket 1, which is fixed in relative position to various devices used for assembling the automobile chassis; a movable component 2 mounted on the mounting bracket 1, the movable component 2 having a vertical trajectory; and a flipping component 3 mounted on the movable component 2, the axis of the flipping component 3 coinciding with the axis of the brake disc 4. The flipping component 3 can uniformly apply a horizontal pressure pointing towards the axis and a vertically upward supporting force to the side of the brake disc 4. The flipping component 3 can drive the brake disc 4 and the wheel hub bearing 5 to rotate relative to the movable component 2. The movable component 2 can drive the flipping component 3 to move relative to the mounting bracket 1.

[0021] Specifically, the mounting bracket 1 is a U-shaped frame with its open end facing the ground. Its bottom two ends are fixed to the ground by bolts, so that its position is fixed relative to other devices fixed to the ground in the automobile chassis assembly line, thereby improving the accuracy of the spline of the drive shaft and the spline hole of the wheel hub bearing 5 in subsequent processes. Secondly, the top of the mounting bracket 1 is connected to the moving component 2 by bolts. The moving component 2 can move along the horizontal line and also along the vertical line, thereby forming a movable vertical plane.

[0022] Furthermore, the tilting assembly 3 is fixed to the moving part of the moving assembly 2 by bolts, enabling it to move relative to the brake disc 4 and the wheel hub bearing 5. Secondly, when the tilting assembly 3 approaches the brake disc 4, it can apply a clamping force to it. The two axes coincide, so that after clamping the brake disc 4, the brake disc 4 is located in the middle position of the tilting assembly 3, avoiding the brake disc 4 from applying additional torque to the tilting assembly 3, which would affect the stability of clamping the brake disc 4. The tilting assembly 3 achieves the function of clamping the brake disc 4 by applying force to the side and bottom surface of the brake disc 4, thereby enabling the moving assembly 2 to move the tilting assembly 3, the brake disc 4 and the wheel hub bearing 5 at the same time.

[0023] In this process, after the flipping component 3 clamps the brake disc 4, the spline hole of the wheel hub bearing 5 is away from the flipping component 3. The flipping component 3 applies torque to the brake disc 4, so that the wheel hub bearing 5 can rotate relative to it, so that its spline hole faces the flipping component 3. This allows the moving component 2 to move it to the next process for spline assembly. The movable moving component 2 can improve the spline assembly accuracy and maintain the spline hole at a fixed height so that the spline of the drive shaft in the subsequent process can be aligned with the spline hole. The moving component 2 moves the spline hole to make the two fit precisely without collision accidents.

[0024] like Figure 2 As shown, the moving component 2 includes: a rodless cylinder 21 and a horizontal slide rail 22 mounted on the mounting bracket 1, the length direction of the rodless cylinder 21 and the horizontal slide rail 22 being horizontal, and the mounting surface of the rodless cylinder 21 and the horizontal slide rail 22 being one side of the mounting bracket 1; a vertical cylinder 24 and a vertical slide rail 25 moving along the rodless cylinder 21, the movement direction of the vertical cylinder 24 being the same as the length direction of the vertical slide rail 25, the vertical cylinder 24 being able to drive the flipping component 3 to move along the vertical slide rail 25, the vertical cylinder 24 and the vertical slide rail 25 being mounted on the same side of the rodless cylinder 21, the rodless cylinder 21 being able to drive the vertical cylinder 24 and the vertical slide rail 25 to move horizontally; and limiting blocks 23 disposed at both ends of the mounting bracket 1 or the rodless cylinder 21 or the horizontal slide rail 22, the limiting blocks 23 at both ends forming the horizontal stroke of the vertical cylinder 24 and the vertical slide rail 25.

[0025] Specifically, the top side of the mounting bracket 1 is a mounting surface, which is a vertical surface. The bottom surfaces of the rodless cylinder 21 and the horizontal slide rail 22 are both fixedly connected to the mounting surface by bolts, so that the moving parts of the rodless cylinder 21 and the horizontal slide rail 22 move along the mounting surface, forming a horizontal movement trajectory. Secondly, the bottom surfaces of the vertical cylinder 24 and the vertical slide rail 25 are simultaneously fixedly connected to the moving parts of the rodless cylinder 21 and the moving parts (slider) of the horizontal slide rail 22 by bolts, so that the rodless cylinder 21 can drive the vertical cylinder 24 and the vertical slide rail 25 to move along the surface of the horizontal slide rail 22, ensuring the stability of the vertical cylinder 24 and the vertical slide rail 25 during movement. Secondly, the vertical cylinder 24... The moving end of 4 is fixedly connected to the flipping assembly 3, which drives the flipping assembly 3 to move along the vertical slide rail 25. At the same time, the rodless cylinder 21 drives the vertical cylinder 24 to move horizontally along the vertical slide rail 25, so that the movement trajectory of the flipping assembly 3 is a vertical plane, thereby enabling it to accurately approach the brake disc 4 and apply clamping force to its side, avoiding collisions during clamping and preventing damage to the surfaces of the brake disc 4 and the wheel hub bearing 5. Meanwhile, the mechanism of the flipping assembly 3 used to clamp the brake disc 4 can rotate, thereby driving the brake disc 4 and the wheel hub bearing 5 to rotate, causing their vertical positions to be reversed, so that the spline hole of the wheel hub bearing 5 faces upward, allowing it to be assembled with the drive shaft of the subsequent process.

[0026] The axes of the flipping assembly 3 and the brake disc 4 coincide, so that the axis position of the flipping assembly 3 is the axis position of the wheel hub bearing 5, that is, the axis position of the flipping assembly 3 is the axis position of the spline hole. Thus, the trajectory of the moving assembly 2 moving the flipping assembly 3 is the moving trajectory of the spline hole, thereby ensuring the moving accuracy of the spline hole and improving the matching accuracy between the wheel hub bearing 5 and the drive shaft of the subsequent process.

[0027] Furthermore, the horizontal slide rail 22 is arranged on both sides of the rodless cylinder 21; the vertical slide rail 25 is arranged on both sides of the vertical cylinder 24.

[0028] Specifically, the vertical cylinder 24 and the vertical slide rail 25 are slidably connected to the horizontal slide rail 22 at both ends of the rodless cylinder 21, so that neither of them applies a torque to the rodless cylinder 21, thereby avoiding the rodless cylinder 21 from being subjected to additional forces that would affect its movement accuracy, and thus improving the movement accuracy of the vertical cylinder 24 and the vertical slide rail 25; the flipping assembly 3 is slidably connected to the vertical slide rail 25 on both sides of the vertical cylinder 24, so that neither of them applies a torque to the vertical cylinder 24, thereby avoiding the vertical cylinder 24 from being subjected to additional forces that would affect its movement accuracy, and thus improving the movement accuracy of the brake disc 4 and the wheel hub bearing 5, and improving the spline fit accuracy.

[0029] like Figure 3As shown, the flipping assembly 3 includes: a fixed plate 31 disposed on the moving assembly 2, the bottom and top surfaces of the fixed plate 31 being horizontal, and the moving assembly 2 being able to drive the fixed plate 31 to move along a vertical plane; at least two clamping arms 32 disposed at both ends of the bottom surface of the fixed plate 31, the clamping arms 32 being able to move towards or away from each other along the bottom surface of the fixed plate 31; rotating claws 33 respectively disposed on opposite sides of the clamping arms 32, the rotating claws 33 being able to rotate at the same angle relative to the side of the clamping arms 32 simultaneously; and a limiting post 36 disposed at one end of the clamping arm 32 near the rotating claw 33, the limiting post 36 being located at both ends of the rotating claw 33, the side of the limiting post 36 away from the fixed plate 31 forming the rotation stroke of the rotating claw 33.

[0030] Specifically, the top surface of the fixed plate 31 and the side surface of the moving component 2 are fixedly connected by a vertical plate, so that the top surface of the fixed plate 31 is perpendicular to the side surface of the moving component 2, thereby making its top surface a horizontal plane. The rodless cylinder 21 drives the fixed plate 31 to move horizontally, and the vertical cylinder 24 drives the fixed plate 31 to move vertically, so that the movement trajectory of the fixed plate 31 is a vertical plane, thereby making the movement trajectory of the clamping arm 32 and the rotating claw 33 a vertical plane.

[0031] The clamping arms 32 are fixedly installed at both ends of the bottom surface of the fixed plate 31 and driven by a bidirectional telescopic cylinder. The movement direction of the bidirectional telescopic cylinder is parallel to the movement direction of the rodless cylinder 21, so that the direction of the clamping arms 32 moving towards or away from each other is parallel to the movement direction of the rodless cylinder 21. The vertical cylinder 24 drives the clamping arms 32 to move closer to the brake disc 4, and the clamping arms 32 move towards each other to clamp the side of the brake disc 4, fixing the horizontal movement of the brake disc 4. Secondly, the end of the clamping arm 32 away from the fixed plate 31 is rotatably connected to a rotating claw 33 and a rotating cylinder. The rotating cylinder drives the rotating claw 33 to move relative to the clamping arm 32, and the clamping arm 32 clamps the brake disc 4 through the rotating claw 33, so that the rotating claw 33 can both apply clamping force to the brake disc 4 and drive the brake disc 4 and the wheel. The hub bearing 5 rotates; next, the horizontal ends of the clamping arm 32 and the side away from the fixed plate 31 are fixedly connected to the limiting post 36. The top surface of the limiting post 36 is away from the fixed plate 31. The top surfaces of the four limiting posts 36 fixedly connected to the clamping arms 32 on both sides can form a plane to limit the rotation of the rotating claw 33. The rotating claw 33 is divided into two parts with the rotation center line. The length of one part is greater than the length of the other part, so that the longer part can contact the limiting post 36, while the shorter part does not contact the top surface of the limiting post 36. This allows the top surface of the limiting post 36 at the same end of the clamping arm 32 on the same side to limit the rotation of the rotating claw 33, thereby limiting its rotation angle. This ensures that the axis of the spline hole of the hub bearing 5 after rotation is vertically upward, which facilitates subsequent spline assembly and improves assembly accuracy.

[0032] Secondly, the end of the limiting post 36 used for installation is equipped with a spring to provide cushioning and prevent hard contact with the rotating claw 33.

[0033] Furthermore, the maximum diameter of the brake disc 4 is within the range of the maximum and minimum stroke of the clamping arm 32.

[0034] Specifically, the stroke of the clamping arm 32 is determined by the stroke of the bidirectional telescopic cylinder. The stroke of the clamping arm 32 can be adjusted by adjusting the size of the bidirectional telescopic cylinder. When the maximum diameter of the brake disc 4 is greater than the maximum stroke, the line of action of the clamping force applied by the clamping arm 32 to the brake disc 4 cannot pass through the center of the brake disc 4, so it cannot clamp the brake disc 4. When the maximum diameter of the brake disc 4 is less than the minimum stroke, the rotating claw 33 can never contact the brake disc 4, and thus cannot clamp the brake disc 4.

[0035] Furthermore, the rotating claws 33 are connected by a telescopic rod 34, the telescopic direction of which is the same as the moving direction of the clamping arm 32; and rollers 35 are provided at both ends of the rotating claws 33 that contact the brake disc 4, the axis of the rollers 35 is parallel to the axis of the brake disc 4, and the side of the rollers 35 can rotate freely relative to the side of the brake disc 4.

[0036] Specifically, one end of the longer portion of the rotating claws 33 on both sides is fixedly connected to a telescopic rod 34. When the clamping arms 32 move towards or away from each other, they drive the rotating claws 33 to move towards or away from each other along the telescopic rod 34, thereby improving the stability of the rotating claws 33 during movement and thus improving the stability after clamping the brake disc 4, preventing accidents such as the brake disc 4 and wheel hub bearing 5 falling off. At the same time, it provides a redundant design for fixing the brake disc. When the rotating cylinder on one side cannot provide force to the rotating claws 33, the rotating cylinder on the other side provides support through the telescopic rod 34, improving the stability during clamping and flipping. Meanwhile, the telescopic rod 34 enables the rotating claws 33 on both sides to form a whole, thereby rotating at the same angle and ensuring flipping accuracy.

[0037] Secondly, the axis of the roller 35 is a vertical line, and its side can rotate automatically, which can improve the stability of clamping. The upper and lower top surfaces of the roller 35 are both raised, which provides vertical support for the brake disc 4 and the wheel hub bearing 5. When the side surface of the roller 35 is rough, it can provide vertical support for the brake disc 4 and the wheel hub bearing through friction, thereby avoiding contact between the top or bottom surface of the brake disc 4 and the roller 35 and causing damage.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
