Description

Technical Field

[0001] This invention relates to the field of press-fit connection component design and development technology, specifically a floating head. Background Technology

[0002] Automotive suspension components or link components require press-fit assembly during production. During the press-fit process, slight offsets may occur at both ends of the link, affecting the accuracy of the press-fit. In fact, forced press-fit may even damage the link, affecting its subsequent use. The existing press-fit process is not designed to move the components to solve the problem of slight offsets during press-fit. It mainly relies on skilled workers to make judgments, which cannot improve the press-fit yield.

[0003] Therefore, a floating head was designed and developed to solve the above problems. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention proposes a floating head. The technical problem to be solved by this invention is achieved through the following technical solution: A floating head includes a fixed end, the fixed end having a floating cavity, floating components distributed within the floating cavity, and a centering component provided within the fixed end to provide tension to drive the floating components to reset. The fixed end is provided with a limiting seat that extends into the floating cavity to fix the centering component. The top of the fixed end is provided with a sealing plate. The floating cavity is provided with at least two sets of guide components to guide the movement of the floating cavity. The floating assembly includes a floating platform that fits into the guide assembly, the floating platform being connected to an adapter that extends out a sealing plate for docking with external parts; Both the floating platform and the adapter are equipped with clearance grooves that engage with the guide assembly.

[0005] The guide assembly includes a plurality of bearing balls distributed circumferentially around the axis of the fixed end. The bearing balls are fitted with limit rings, and wear-resistant rings abut against both the upper and lower ends of the bearing balls.

[0006] The centering component is a rectangular spring, one end of which engages with the limiting seat, and the end of the rectangular spring away from the limiting seat engages with the floating component.

[0007] The centering component is a conical helical spring, the bottom surface of which engages with the limiting seat, and one end of the limiting seat engages with the floating component.

[0008] The beneficial effects of the present invention are: the present invention provides tension through the centering component so that the floating component can automatically return to its original position after displacement in the floating cavity. At the same time, the guide component provides auxiliary guidance when the floating component is displaced, thereby reducing the friction between the floating component and the fixed end and the sealing plate and improving the overall service life.

[0012] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described more clearly and completely below with reference to the accompanying drawings in the embodiments. Of course, the described embodiments are only a part of the present invention and not all of it. Based on this embodiment, other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of the present invention.

[0013] This invention includes the following embodiments: Embodiment 1: like Figures 1 to 2 As shown, a floating head includes a fixed end 1, the fixed end 1 having a floating cavity 2, floating components 3 distributed in the floating cavity 2, and a centering component 4 provided in the fixed end 1 to provide tension to drive the floating components 3 to reset. The fixed end 1 is provided with a limiting seat 5 that extends into the floating cavity 2 to fix the centering component 4. The top of the fixed end 1 is provided with a sealing plate 6. The floating cavity 2 is provided with at least two sets of guide components 7 to guide the movement of the floating cavity 2. The floating component 3 includes a floating platform 31 that fits into the guide component 7. The floating platform 31 is connected to an adapter 32, which extends out of the sealing plate 6 to dock with external parts. Both the floating platform 31 and the adapter 32 are provided with clearance grooves 33 that engage with the guide assembly 7; the diameter of the floating cavity 2 is larger than the diameter of the floating platform 31 and the adapter 32; the floating platform 31 and the adapter 32 are connected by screws, and the sealing plate 6 and the fixed end 1 are connected by screws.

[0014] The guide assembly 7 includes a plurality of bearing balls 71 arranged circumferentially around the axis of the fixed end 1. Each bearing ball 71 is fitted with a limiting ring 72, and wear-resistant rings 73 abut against both the upper and lower ends of each bearing ball 71. Figure 2 As shown, in the guide assembly 7 near the sealing plate 6, one side of the wear-resistant ring 73 is attached to the inner surface of the sealing plate 6, and the other side of the wear-resistant ring 73 is attached to the adapter 32; in the guide assembly 7 near the fixed end 1, one side of the wear-resistant ring 73 is attached to the floating platform 31, and the other side of the wear-resistant ring 73 is attached to the inner wall of the fixed end 1.

[0015] The centering component 4 is a rectangular spring 41. One end of the rectangular spring 41 is engaged with the limiting seat 5, and the end of the rectangular spring 41 away from the limiting seat 5 is engaged with the floating component 3. During the pressing process, the adapter 32 is displaced, which simultaneously drives the floating platform 31 to move together. The displacement of the floating platform 31 and the adapter 32 causes the rectangular spring 41 to twist. After the pressing is completed, the rectangular spring 41 returns to its original position through its elastic force, which in turn drives the floating platform 31 and the adapter 32 to their original positions.

[0016] Example 2: like Figures 3 to 4 As shown, a floating head includes a fixed end 1, the fixed end 1 having a floating cavity 2, floating components 3 distributed in the floating cavity 2, and a centering component 4 provided in the fixed end 1 to provide tension to drive the floating components 3 to reset. The fixed end 1 is provided with a limiting seat 5 that extends into the floating cavity 2 to fix the centering component 4. The top of the fixed end 1 is provided with a sealing plate 6. The floating cavity 2 is provided with at least two sets of guide components 7 to guide the movement of the floating cavity 2. The floating component 3 includes a floating platform 31 that fits into the guide component 7. The floating platform 31 is connected to an adapter 32, which extends out of the sealing plate 6 to dock with external parts. Both the floating platform 31 and the adapter 32 are provided with clearance grooves 33 that engage with the guide assembly 7; the floating platform 31 and the adapter 32 are connected by screws, and the sealing plate 6 and the fixed end 1 are connected by screws.

[0017] The guide assembly 7 includes a plurality of bearing balls 71 arranged circumferentially around the axis of the fixed end 1. Each bearing ball 71 is fitted with a limiting ring 72, and wear-resistant rings 73 abut against both the upper and lower ends of each bearing ball 71. Figure 4 As shown, in the guide assembly 7 near the sealing plate 6, one side of the wear-resistant ring 73 is attached to the inner surface of the sealing plate 6, and the other side of the wear-resistant ring 73 is attached to the adapter 32; in the guide assembly 7 near the fixed end 1, one side of the wear-resistant ring 73 is attached to the floating platform 31, and the other side of the wear-resistant ring 73 is attached to the inner wall of the fixed end 1.

[0018] The centering component 4 is a conical helical spring 42. The bottom surface of the conical helical spring 42 engages with the limiting seat 5, and one end of the limiting seat 5 engages with the floating component 3. During the pressing process, the adapter 32 is displaced, which simultaneously drives the floating platform 31 to move. The displacement of the floating platform 31 and the adapter 32 causes the conical helical spring 42 to twist. After the pressing is completed, the conical helical spring 42 resets through its elastic force, which in turn resets the floating platform 31 and the adapter 32. The upper elastic force of the conical helical spring 42 is less than the lower elastic force, which can be adapted to reduce the torsion of the spring and reduce the shaking of the floating component 3 when it resets.

[0019] Example 3: like Figures 5 to 8 As shown, a floating head includes a fixed end 1, the fixed end 1 having a floating cavity 2, floating components 3 distributed in the floating cavity 2, and a centering component 4 provided in the fixed end 1 to provide tension to drive the floating components 3 to reset. The fixed end 1 is provided with a limiting seat 5 that extends into the floating cavity 2 to fix the centering component 4. The top of the fixed end 1 is provided with a sealing plate 6. The floating cavity 2 is provided with at least two sets of guide components 7 to guide the movement of the floating cavity 2. The floating component 3 includes a floating platform 31 that fits into the guide component 7. The floating platform 31 is connected to an adapter 32, which extends out of the sealing plate 6 to dock with external parts. Both the floating platform 31 and the adapter 32 are provided with clearance grooves 33 that engage with the guide assembly 7; the floating platform 31 and the adapter 32 are connected by screws, and the sealing plate 6 and the fixed end 1 are connected by screws.

[0020] The guide assembly 7 includes a plurality of bearing balls 71 arranged circumferentially around the axis of the fixed end 1. Each bearing ball 71 is fitted with a limiting ring 72, and wear-resistant rings 73 abut against both the upper and lower ends of each bearing ball 71. Figure 6 As shown, in the guide assembly 7 near the sealing plate 6, one side of the wear-resistant ring 73 is attached to the inner surface of the sealing plate 6, and the other side of the wear-resistant ring 73 is attached to the adapter 32; in the guide assembly 7 near the fixed end 1, one side of the wear-resistant ring 73 is attached to the floating platform 31, and the other side of the wear-resistant ring 73 is attached to the inner wall of the fixed end 1.

[0021] The centering component 4 includes a slider 8 slidably installed in the adapter 32. The centering component 4 also includes a centering tension spring 43 that engages with the slider 8 and the limiting seat 5. The adapter 32 is provided with a groove 34 that cooperates with the slider 8.

[0022] The slider 8 is equipped with a locking assembly 9 that fixes the slider 8 and adjusts the tension of the centering spring 43.

[0023] The centering spring 43 is provided with hooks 431 at both its upper and lower ends, and the hooks 431 are respectively engaged with the slider 8 and the limiting seat 5; for example Figure 8 As shown, hook 431 is engaged with slider 8 and limit seat 5 respectively. During pressing, when floating platform 31 and adapter 32 are displaced, they simultaneously drive centering spring 43 to twist. After pressing is completed, centering spring 43 drives floating platform 31 and adapter 32 to reset through elastic force.

[0024] The locking assembly 9 includes a first adjusting screw 91 disposed on the adapter 32 and distributed along the axis of the adapter 32 to be threadedly engaged with the slider 8. The locking assembly 9 also includes two oblong holes 10 disposed circumferentially on the fixed end 1 and symmetrically distributed along the radius of the fixed end 1. A second adjusting bolt 92 is disposed in the oblong holes 10.

[0025] The slider 8 is provided with a first threaded groove 81 that mates with the first adjusting screw 91. The slider 8 is also provided with second threaded grooves 82 that are symmetrically distributed in the horizontal direction to mate with the second adjusting bolt 92. By rotating the first adjusting screw 91, the position of the slider 8 in the slide groove 34 is adjusted to adjust the elastic force of the centering spring 43. After the height of the slider 8 is adjusted, the second adjusting bolt 92 is placed into the waist-shaped hole 10, and the second adjusting bolt 92 mates with the second threaded groove 82 to fix the position of the slider 8.
