The first connector is used to connect to a press; the second connector is used to connect to a pressing head. The second connector has a receiving portion, at least a portion of the first connector is located within the receiving portion, and a first gap is formed between the first connector and the receiving portion. When the second connector is subjected to an external force, it can deflect relative to the first connector to drive the pressing head connected to the second connector to rotate.

[0002] Press-fitting equipment is a commonly used mechanical device used to press two parts together. In related technologies, the press head of press-fitting equipment generally uses a rigid connection, thus requiring high tolerances between the various parts of the equipment; and during use, if there are deviations in the placement and fit of the parts, press-fitting failure is likely to occur. Utility Model Content

[0003] In order to overcome the above-mentioned defects in related technologies, the purpose of this application is to provide a self-aligning component and a pressing device. This application can make the pressing head fit tightly against the part to be pressed, eliminate the parallelism tolerance between the pressing head and the part to be pressed, realize the self-alignment of the pressing head, and improve the success rate of part pressing.

[0004] On the one hand, this application provides a self-correcting component, including:

[0005] A first connector is used to connect to the press;

[0006] The second connector is used to connect the pressure head; the second connector has a receiving portion, at least a portion of the first connector is located in the receiving portion, and a first gap is formed between the first connector and the receiving portion;

[0007] When the second connector is subjected to an external force, it can deflect relative to the first connector to drive the pressure head connected to the second connector to rotate.

[0008] In one possible implementation, the first connector includes a first shaft segment and a second shaft segment, the diameter of the first shaft segment being larger than the diameter of the second shaft segment, the first shaft segment being used to connect the press, and the receiving portion including a first hole segment, with at least a portion of the second shaft segment located within the first hole segment.

[0013] In one possible implementation, the receiving portion further includes a second hole segment connected to the first hole segment, the second hole segment having a sliding member therein, the sliding member abutting against the second hole segment and the second shaft segment.

[0014] In one possible implementation, the second hole segment is conical, and the slider includes a metal ball whose center is located on the axis of the second hole segment.

[0015] In one possible implementation, an elastic element is also provided between the first hole segment and the second shaft segment.

[0016] In one possible implementation, the elastic element includes a rubber ring that is fitted onto the second shaft segment and abuts against the first hole segment.

[0017] On the other hand, this application provides a pressing device, including a frame, a press, a pressing head, and a clamp. The frame includes a top plate, a bottom plate, and a plurality of support columns, all of which are disposed between the top plate and the bottom plate. The output end of the press passes through the top plate and is connected to the pressing head. The clamp is disposed on the bottom plate.

[0018] This application provides a self-aligning component and a pressing device. The self-aligning component includes a first connector and a second connector. The first connector is used to connect to a press; the second connector is used to connect to a pressing head. The second connector has a receiving portion, at least a portion of the first connector is located within the receiving portion, and a first gap is formed between the first connector and the receiving portion. When the second connector is subjected to an external force, it can deflect relative to the first connector to drive the pressing head connected to the second connector to rotate. By placing at least a portion of the first connector within the second connector, and establishing a gap between the first and second connectors, this application allows the second connector to deflect relative to the first connector when subjected to an external force, thereby driving the pressing head connected to the second connector to rotate. This makes the pressing head press against the part to be pressed, eliminating the parallelism tolerance between the pressing head and the part to be pressed, achieving self-alignment of the pressing head, and improving the success rate of part pressing.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0034] Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0035] As described in the background section, the press heads of press-fitting equipment in related technologies generally employ rigid connections, thus requiring high tolerances between different parts of the equipment. Furthermore, during use, deviations in the placement and fit of parts can easily lead to press-fitting failure. For example, when pressing a top cover onto the outer casing, if there is a parallelism tolerance between the top cover and the press head, one side of the top cover may be higher than the other. During press-fitting, the press head first contacts the higher side of the top cover and applies downward pressure, resulting in uneven force distribution on the top cover and a risk of press-fitting failure between the top cover and the outer casing.

[0036] In view of this, the present application aims to provide a self-aligning component and a pressing device. The self-aligning component is disposed between a press and a pressing head, and includes a first connector and a second connector. The first connector is used to connect to the press; the second connector is used to connect to the pressing head; the second connector has a receiving portion, at least a portion of the first connector is located in the receiving portion, and a first gap is formed between the first connector and the receiving portion; wherein, when the second connector is subjected to an external force, it can deflect relative to the first connector to drive the pressing head connected to the second connector to rotate, so that the pressing head is close to the part to be pressed, eliminating the parallelism tolerance between the pressing head and the part to be pressed, realizing the self-alignment of the pressing head, which is beneficial to improving the success rate of part pressing.

[0037] The embodiments of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can gain a more detailed understanding of the content of this application. It should be noted that, in the description of this embodiment, the first direction X and the second direction Y are two different directions in space. For example, the first direction X and the second direction Y can be perpendicular to each other, and the second direction Y can be, for example, a vertical direction.

[0038] Please refer to Figure 1 This embodiment provides a self-aligning component 10, including:

[0039] A first connector 100 is used to connect to the press 20. For example, the first connector 100 can be fixedly connected to the output end of the press 20 by means of bolts or other parts, so that it moves together with the output end of the press 20.

[0040] A second connector 200 is used to connect to the pressure head 30. Exemplarily, the second connector 200 can be fixedly connected to the pressure head 30 by means such as bolts. The second connector 200 has a receiving portion 210, which can be, for example, a groove formed in the second connector 200. At least a portion of the first connector 100 is located within the receiving portion 210, and a first gap is formed between the first connector 100 and the receiving portion 210. It is understood that a corresponding limiting fit structure should be provided between the first connector 100 and the second connector 200 to prevent the first connector 100 from falling out of the receiving portion 210.

[0041] The first gap between the first connecting member 100 and the receiving part 210 ensures that the second connecting member 200 can deflect at a certain angle relative to the first connecting member 100 when subjected to external force. This causes a certain deflection between the axis of the first connecting member 100 and the axis of the second connecting member 200. When the second connecting member 200 deflects, it can drive the pressure head 30 connected to the second connecting member 200 to rotate, thereby adjusting the angle of the pressure head 30. In other words, the press 20 and the pressure head 30 can be movably connected through the first connecting member 100 and the second connecting member 200, thereby reducing the parallelism tolerance requirements between the pressure head 30 and the part to be pressed, achieving self-alignment of the pressure head 30, and improving the success rate of part pressing.

[0042] In this embodiment, at least a portion of the first connector 100 is disposed within the second connector 200, and there is a gap between the first connector 100 and the second connector 200. When the second connector 200 is subjected to external force, it can deflect relative to the first connector 100, thereby driving the pressure head 30 connected to the second connector 200 to rotate, so that the pressure head 30 is pressed tightly against the part to be pressed, realizing the self-alignment of the pressure head 30, which is beneficial to improving the success rate of part pressing.

[0043] Please continue to refer to Figure 1 In this embodiment, the first connecting member 100 includes a first shaft segment 110 and a second shaft segment 120. The diameter of the first shaft segment 110 is larger than the diameter of the second shaft segment 120, and the two form a stepped shaft structure. The first shaft segment 110 is used to connect to the press 20. For example, several through holes can be formed in the first shaft segment 110, and fasteners such as screws can be passed through the through holes to fix it to the press 20. The receiving portion 210 includes a first hole segment 211, and at least a portion of the second shaft segment 120 is located within the first hole segment 211; that is, in this embodiment, the first connecting member 100 is connected to the second connecting member 200 via the second shaft segment 120 and the first hole segment 211.

[0044] Furthermore, in this embodiment, the first gap between the second shaft segment 120 and the first hole segment 211 is less than or equal to 0.5 mm. By setting the first gap within the above range, it can be ensured that after the pressure head 30 is subjected to the reaction force of the part to be pressed, the second connecting member 200 can quickly abut against the first connecting member 100, thereby causing the first connecting member 100 and the second connecting member 200 to deflect relative to each other. This allows the second connecting member 200 to drive the pressure head 30 to deflect as a whole, making the pressure head 30 fit tightly against the part to be pressed, thus achieving self-alignment of the pressure head 30.

[0045] Please continue to refer to Figure 1In this embodiment, the second connector 200 is also provided with a plurality of through holes. The plurality of through holes are arranged at intervals along the circumference of the second connector 200, and the through holes are connected to the first hole segment 211.

[0046] The self-aligning component 10 also includes multiple fasteners 220, each of which corresponds to a single through hole. After passing through the corresponding through hole, the fasteners 220 are fixedly connected to the second shaft segment 120.

[0047] For example, the fixing member 220 in this embodiment can be a fixing pin, with part of the fixing pin located in the through hole and another part of the fixing pin passing through the second shaft section 120. The second shaft section 120 can be provided with a plurality of grooves, which correspond one-to-one with the plurality of through holes. Alternatively, the second shaft section 120 can be provided with a ring groove to facilitate connection with the fixing pin. The fixing pin is used to achieve a limiting fit between the first connecting member 100 and the second connecting member 200, preventing the first connecting member 100 from falling out of the receiving part 210.

[0048] Furthermore, in this embodiment, a second gap is formed between the fixing member 220 and the corresponding through hole. With the above structure, it can be ensured that when the second connecting member 200 is deflected relative to the first connecting member 100, the fixing member 220 can also abut against the second connecting member 200, reducing the difficulty of deflecting the second connecting member 200.

[0049] Please continue to refer to Figure 1 In this embodiment, the receiving portion 210 further includes a second hole segment 212 connected to the first hole segment 211. A sliding member 230 is provided within the second hole segment 212, and the sliding member 230 abuts against the second hole segment 212 and the second shaft segment 120. By providing the sliding member 230 between the first connecting member 100 and the second connecting member 200, this embodiment can reduce the resistance encountered by the second connecting member 200 when it deflects relative to the first connecting member 100.

[0050] Specifically, the second hole segment 212 in this embodiment can be conical, bowl-shaped or hemispherical, etc., that fits against the slider 230. The slider 230 includes a metal ball, which is located in the second hole segment 212 and the surface of the metal ball is tangent to the inner surface of the second hole segment 212. The second hole segment 212 can limit the metal ball and prevent the metal ball from moving in the second connector 200 when the second connector 200 is deflected relative to the first connector 100.

[0051] The center of the metal ball is located on the axis of the second hole segment 212. Before the first connector 100 is deflected relative to the second connector 200, the axis of the first connector 100 and the axis of the second connector 200 coincide, and both coincide with the center of the metal ball.

[0052] Please continue to refer to Figure 1 In this embodiment, an elastic element 300 is also provided between the first hole segment 211 and the second shaft segment 120. When the second connecting member 200 deflects relative to the first connecting member 100, one side of the second connecting member 200 can compress the elastic element 300, thereby allowing the elastic element 300 to store a certain amount of elastic potential energy. After deflection, the elastic potential energy stored in the elastic element 300 is used to restore the second connecting member 200 to its initial state, thus facilitating its next use.

[0053] Optionally, the elastic element 300 in this embodiment includes a rubber ring, which is sleeved on the second shaft segment 120 and abuts against the first hole segment 211. Since the rubber ring is circumferentially disposed on the outer side of the second shaft segment 120, the second connecting member 200 can abut against the rubber ring regardless of its orientation, ensuring that the rubber ring can be used to straighten the second connecting member 200 subsequently. In this embodiment, multiple rubber rings can be disposed on the second shaft segment 120, with the multiple rubber rings spaced apart along the axial direction of the second shaft segment 120.

[0054] In other possible implementations, the elastic element 300 may also include a plurality of elastic pads, which are spaced apart circumferentially along the second shaft segment 120. In this implementation, when the second connector 200 deflects, it can abut against the corresponding elastic pads, ensuring that the second connector 200 can be straightened using the elastic pads in the future.

[0055] Figures 2(a)-2(c) A schematic diagram of the self-aligning component pressing process in this embodiment is shown.

[0056] As shown in Figure 2(a), before pressing, the axis of the first connector 100 and the axis of the second connector 200 coincide, and there is a certain parallelism tolerance between the press head 30 and the part to be pressed 1000, so that one side of the part to be pressed 1000 (the right side of the first direction X in the figure) is closer to the press head 30, while the other side of the part to be pressed 1000 (the left side of the first direction X in the figure) is farther from the press head 30. At this time, the self-aligning component 10 drives the pressure head 30 to press downward along the second direction Y. The pressure head 30 first contacts the part to be pressed 1000 on the right side along the first direction X. After contact, the part to be pressed 1000 gives the pressure head 30 a reaction force (shown by the dotted line on the right side of the figure, and the arrow indicates the direction of the force). Since the second connector 200 is fixedly connected to the pressure head 30, under the action of the reaction force of the part to be pressed 1000, the second connector 200 deflects relative to the first connector 100. The first connector 100 provides a force to the second connector 200 (shown by the dotted line on the left side of the figure, and the arrow indicates the direction of the force), so that the second connector 200 and the pressure head 30 as a whole deflect in the counterclockwise direction shown in the figure, reaching the state shown in Figure 2(b), so that the pressure head 30 and the surface of the part to be pressed 1000 are completely in contact, thereby eliminating the influence of the parallelism tolerance between the pressure head 30 and the part to be pressed 1000, and ensuring that the part to be pressed 1000 can be pressed smoothly. In the state shown in Figure 2(b), the second connector 200 compresses the elastic member 300, causing the elastic member 300 to store a certain amount of elastic potential energy. After pressing is completed, the elastic restoring force of the elastic member 300 acts on the second connector 200, thereby straightening the second connector to the state shown in Figure 2(c), so that it can be used for the next pressing.

[0057] It is understood that the self-aligning component 10 in this embodiment can reduce the parallelism tolerance requirements between the pressure head 30 and the part to be pressed, realize the self-alignment of the pressure head 30, and help improve the success rate of part pressing.

[0058] Please refer to Figure 3 This embodiment also provides a pressing device, including a frame, a press 20, a pressing head 30, and a clamp 50. The frame includes a top plate 41, a bottom plate 42, and multiple support columns 43, which are all disposed between the top plate 41 and the bottom plate 42 to form a frame structure, facilitating the installation of other components. The output end of the press 20 passes through the top plate 41 and connects to the pressing head 30. The press 20 can be, for example, a servo press, whose output end passes through the top plate 41 and connects to the pressing head 30. The clamp 50 is disposed on the bottom plate 42, and the parts to be pressed can be placed in the clamp 50 and fixed by the clamp 50 to prevent the parts to be pressed from moving during the pressing process.

[0059] In this embodiment, the self-aligning component 10 is provided between the output end of the press 20 and the press head 30. It can be understood that, due to the use of the self-aligning component 10, the parallelism tolerance requirements between the components in the pressing equipment can be reduced, and the self-alignment of the press head 30 can be achieved, which is beneficial to improving the success rate of part pressing.
