Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary tooling, and in particular relates to a pressing device. Background Technology

[0002] To ensure the airtightness of high-voltage connectors in new energy vehicles, a sealing ring is typically designed at the point where the high-voltage connector assembles with the aluminum housing. This ensures a tight seal between the two components. However, due to the elasticity of the sealing ring, it is difficult to press the aluminum housing into place in one go during the high-voltage connector assembly process. Currently, factories commonly use manual assembly to achieve this, which not only suffers from low assembly efficiency and high labor intensity for workers, but also makes it difficult to guarantee the consistency of the final product's performance, severely impacting production quality and efficiency. Utility Model Content

[0003] In view of this, it is necessary to provide a press-fitting device for solving the above-mentioned technical problems.

[0004] A press-fitting device is used to press an aluminum housing into a high-voltage connector fitted with a sealing ring, so as to achieve a sealed assembly between the aluminum housing and the high-voltage connector; the press-fitting device includes:

[0005] A fixed base plate is fitted with a contoured sleeve, which is used to insert and mate with the high-voltage connector and to support the high-voltage connector.

[0006] A movable plate is positioned above the fixed base plate in the vertical direction. The movable plate and the fixed base plate are slidably connected by guide posts. A through hole is provided on the movable plate for the high-voltage connector inside the conformal sleeve to pass through.

[0007] An elastic support mechanism is disposed between the fixed base plate and the movable plate and abuts against both the fixed base plate and the movable plate respectively, for elastically supporting the movable plate;

[0008] A pressure block is positioned above the movable plate in the vertical direction. The pressure block can press down on the aluminum housing so that the aluminum housing is assembled with the portion of the high-voltage connector that passes through the movable plate.

[0009] The limiting mechanism can abut against and limit the movable plate in the vertical direction, and is used to control the rebound distance of the movable plate under the drive of the elastic support mechanism.

[0010] Understandably, by using an elastic support mechanism to elastically support the movable plate and a limiting mechanism to limit the rebound distance of the movable plate, the pressing device can, during the process of pressing the aluminum shell into the high-voltage connector, achieve the assembly of the sealing ring between the high-voltage connector and the aluminum shell with a single press of the aluminum shell. On the other hand, it can also prevent excessive rebound of the movable plate from damaging the assembly between the aluminum shell and the high-voltage connector. In this way, the pressing device can assist workers in pressing the aluminum shell into the high-voltage connector, thereby improving assembly efficiency, reducing labor intensity, and ensuring the consistency of the product obtained after the high-voltage connector and the aluminum shell are assembled.

[0011] In one embodiment, the elastic support mechanism includes a compression spring, which is disposed corresponding to the guide post and is fitted onto the corresponding guide post.

[0012] Understandably, fitting the compression spring of the elastic support movable plate onto the guide post facilitates the assembly of the compression spring on the guide post and ensures the stability of the compression spring assembly between the fixed base plate and the movable plate.

[0013] In one embodiment, the number of guide posts is configured to be four, and the four guide posts are arranged at the four corners of the movable plate.

[0014] Understandably, four guide posts placed at the four corners of the movable plate are used to guide the assembly of the movable plate on the fixed base plate, thus ensuring the consistency of the direction of the movable plate when it moves relative to the fixed base plate.

[0015] In one embodiment, a linear bearing is mounted on the movable plate, the linear bearing is correspondingly arranged with the guide post, and the linear bearing is fitted onto the corresponding guide post and slidably connected to the guide post;

[0016] The guide post is connected and fixed to the base plate.

[0017] Understandably, the movable plate is slidably connected to the corresponding guide column via linear bearings, which reduces the frictional resistance experienced by the movable plate when it performs telescopic movements relative to the fixed base plate.

[0018] In one embodiment, a limiting piece is connected to one end of the guide post that passes through the linear bearing. The limiting piece can abut against the linear bearing to limit the movable plate to the guide post.

[0019] Understandably, the contact between the limiting plate and the linear bearing bracket can prevent the movable plate from detaching from the guide post during the rebound process.

[0020] In one embodiment, the limiting mechanism includes a limiting seat, a limiting block, and an elastic element. The limiting block is slidably mounted on the limiting seat, and the elastic element abuts against the limiting block in a pre-compressed manner to push the limiting block partially out of the limiting seat and limit the movable plate.

[0021] The limiting block has a wedge-shaped surface, and the movable plate can push against the limiting block through the wedge-shaped surface to compress the elastic member, so that the movable plate passes through the limiting block in the vertical direction.

[0022] It is understandable that, through the structural design of the aforementioned limiting mechanism, the limiting mechanism can precisely limit the rebound stroke of the movable plate while ensuring that the movement of the movable plate toward the fixed base plate is not interfered with, thereby achieving stable and reliable displacement control of the movable plate.

[0023] In one embodiment, the limiting mechanism further includes a handle, the handle portion extending into the limiting seat and connected to the limiting block, for driving the limiting block away from the movable plate and releasing the limiting of the movable plate; and the elastic element is fitted onto the portion of the handle located within the limiting seat.

[0024] The handle can abut against the limiting seat to limit the movement of the limiting block when it extends out of the limiting seat.

[0025] Understandably, the above structural design allows for manual release between the limit block and the movable plate, facilitating operation and creating conditions for the subsequent reuse of the press-fitting device.

[0026] In one embodiment, the limiting seat is disposed on the outside of the fixed base plate, and the limiting seat and the fixed base plate are connected by a threaded component.

[0027] It is understandable that the limit seat is fixed to the base with threaded parts, which facilitates the assembly of the limit seat on the fixed base plate.

[0028] In one embodiment, the pressing device further includes a telescopic drive component, which is connected to the lower pressing block for pushing the lower pressing block down to press the aluminum housing.

[0029] Understandably, using a telescopic drive to automatically control the pressing block to press down on the aluminum housing can further reduce the labor intensity of workers and facilitate their operation.

[0030] In one embodiment, the pressing device further includes a pressure sensor mounted on the lower pressing block and electrically connected to the telescopic drive member, for detecting the pressure value when the lower pressing block presses down on the aluminum shell and generating a feedback signal;

[0031] The feedback signal is used to control the operation of the telescopic drive component.

[0032] It is understandable that the pressure value measured by the pressure sensor when the pressure block is pressed down is used to control the operation of the telescopic drive component. This allows for control of the pressure value when the pressure block presses down on the aluminum housing, thus meeting the usage requirements of assembling the aluminum housing on the high-voltage connector.

[0033] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0034] The press-fitting device claimed in this application uses an elastic support mechanism to elastically support a movable plate and a limiting mechanism to limit the rebound distance of the movable plate. This allows the press-fitting device to achieve the assembly of the sealing ring between the high-voltage connector and the aluminum housing in a single press of the aluminum housing, while also preventing excessive rebound of the movable plate that could damage the assembly between the aluminum housing and the high-voltage connector. Thus, the press-fitting device can assist workers in pressing the aluminum housing into the high-voltage connector, thereby improving assembly efficiency, reducing labor intensity, and ensuring the consistency of the assembled product between the high-voltage connector and the aluminum housing.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0043] The press-fitting device 100 claimed in this application is used to press an aluminum housing 200 onto a high-voltage connector 400 fitted with a sealing ring 300, so as to achieve a sealed assembly between the aluminum housing 200 and the high-voltage connector 400. Here, both the high-voltage connector 400 and the aluminum housing 200 are conventional existing structures in new energy vehicles, and will not be described in detail here.

[0044] like Figure 1 , Figure 2As shown, the press-fitting device 100 claimed in this application includes a fixed base plate 10, a movable plate 20, an elastic support mechanism 30, a lower pressing block 40, and a limiting mechanism 50. A conformal sleeve 11 is mounted on the fixed base plate 10, which is used to insert and cooperate with a high-voltage connector 400 and to support the high-voltage connector 400. The movable plate 20 is located above the fixed base plate 10 in the vertical direction Z. The movable plate 20 and the fixed base plate 10 are slidably connected by a guide post 12. A through hole 21 is provided on the movable plate 20 for the high-voltage connector 400 to pass through the conformal sleeve 11. The connector 400 extends outwards; the elastic support mechanism 30 is disposed between the fixed base plate 10 and the movable plate 20 and abuts against both the fixed base plate 10 and the movable plate 20 respectively, for elastically supporting the movable plate 20; the pressing block 40 is disposed above the movable plate 20 in the vertical direction Z, and the pressing block 40 can press down the aluminum shell 200 so that the aluminum shell 200 is assembled with the part of the high-voltage connector 400 that passes through the movable plate 20; the limiting mechanism 50 can abut against the movable plate 20 in the vertical direction Z and limit its movement, for controlling the rebound distance of the movable plate 20 under the drive of the elastic support mechanism 30. Here, the contour sleeve 11 is contoured relative to the high-voltage connector 400.

[0045] As can be seen from the above, the pressing device 100 of this application uses an elastic support mechanism 30 to elastically support the movable plate 20 and a limiting mechanism 50 to limit the rebound distance of the movable plate 20. This allows the pressing device 100 to press the aluminum shell 200 into the high-voltage connector 400 in one press, thereby achieving the assembly of the sealing ring 300 between the high-voltage connector 400 and the aluminum shell 200. On the other hand, it can also prevent the movable plate 20 from rebounding excessively and damaging the assembly between the aluminum shell 200 and the high-voltage connector 400. In this way, the pressing device 100 can assist workers in pressing the aluminum shell 200 into the high-voltage connector 400, thereby improving assembly efficiency, reducing labor intensity, and ensuring the consistency of the product obtained after the high-voltage connector 400 and the aluminum shell 200 are assembled.

[0046] It should be noted that when the worker uses the press-fit device 100, he first inserts the high-voltage connector 400 with the sealing ring 300 through the through hole 21 on the movable plate 20 into the conformal sleeve 11, then puts the aluminum shell 200 with lubricated oil into the part of the high-voltage connector 400 that protrudes from the movable plate 20, and finally uses the lower pressure block 40 to press down the aluminum shell 200 to achieve the assembly of the aluminum shell 200 on the high-voltage connector 400.

[0047] like Figure 2As shown, in one embodiment, the number of guide posts 12 is configured as four, and the four guide posts 12 are arranged at the four corners of the movable plate 20, so that the movable plate 20 can perform telescopic movement relative to the fixed base plate 10 under the guidance of the four guide posts 12, thereby ensuring the consistency of the direction of the telescopic movement of the movable plate 20 relative to the fixed base plate 10. Here, both the movable plate 20 and the fixed base plate 10 can be configured as cuboid structures. It is understood that in other embodiments, the number of guide posts 12 may also be three, two, etc., which will not be elaborated here.

[0048] like Figure 2 As shown, in one embodiment, a limiting post 13 is provided on the fixed base plate 10. The limiting post 13 can abut against the movable plate 20 to limit the movement stroke of the movable plate 20 when it moves toward the fixed base plate 10. Here, the number of limiting posts 13 is configured to be two, and they can be fixed to the fixed base plate 10 by welding.

[0049] like Figure 1 , Figure 2 As shown, in one embodiment, a linear bearing 22 is installed on the movable plate 20. The linear bearing 22 is correspondingly arranged with the guide post 12, and the linear bearing 22 is fitted onto the corresponding guide post 12 and slidably connected to the guide post 12. This allows the movable plate 20 to slide on the guide post 12 via the linear bearing 22, thereby realizing the telescopic movement of the movable plate 20 relative to the fixed base plate 10. During this process, the linear bearing 22 can reduce the frictional resistance encountered by the movable plate 20 when it performs telescopic movement relative to the fixed base plate 10. Here, the guide post 12 is connected and fixed to the fixed base plate 10, specifically by welding.

[0050] like Figure 1 , Figure 2 As shown, in this embodiment, a limiting piece 121 is connected to one end of the guide post 12 that passes through the linear bearing 22. The limiting piece 121 can abut against the linear bearing 22 to limit the movable plate 20 to the guide post 12, thereby preventing the movable plate 20 from detaching from the guide post 12 during the rebound process. Here, the limiting piece 121 can be specifically fixed to the guide post 12 by screws 122.

[0051] like Figure 1 , Figure 2As shown, in one embodiment, the elastic support mechanism 30 includes a compression spring 31, which is correspondingly disposed with the guide post 12 and is fitted onto the corresponding guide post 12. This facilitates the assembly of the compression spring 31 on the guide post 12 and ensures the stability of the compression spring 31 assembled between the fixed base plate 10 and the movable plate 20. Here, the number of compression springs 31 is also configured to be four, so that the elastic support mechanism 30 can support the four corners of the movable plate 20.

[0052] like Figure 3 As shown, in one embodiment, the limiting mechanism 50 includes a limiting seat 51, a limiting block 52, and an elastic member 53. The limiting block 52 is slidably mounted on the limiting seat 51, and the elastic member 53 abuts against the limiting block 52 in a pre-compressed manner to push the limiting block 52 partially out of the limiting seat 51 and to limit the movable plate 20. The limiting block 52 has a wedge-shaped surface 521, and the movable plate 20 can push the limiting block 52 to compress the elastic member 53 through the wedge-shaped surface 521 so that the movable plate 20 passes through the limiting block 52 in the vertical direction Z. When the movable plate 20 moves toward the fixed base plate 10, the wedge-shaped surface 521 pushes against the limiting block 52, compressing the elastic element 53, so that the limiting block 52 avoids the movable plate 20. When the limiting block 52 loses the push from the movable plate 20, it can extend again from the limiting seat 51 under the elastic push of the elastic element 53 to limit the rebound of the movable plate 20. In other words, the limiting mechanism 50 of this embodiment can accurately limit the rebound stroke of the movable plate 20 while ensuring that the movement of the movable plate 20 toward the fixed base plate 10 is not interfered with, thereby achieving stable and reliable displacement control of the movable plate 20.

[0053] like Figure 1 , Figure 2 As shown, in this embodiment, the limiting seat 51 is disposed on the outer side of the fixed base plate 10, and the limiting seat 51 is connected to the fixed base plate 10 by a threaded component 501, which facilitates the installation of the limiting seat 51 onto the fixed base plate 10. Here, the threaded component 501 can specifically be a screw, bolt, etc.

[0054] like Figure 3As shown, in this embodiment, the limiting mechanism 50 further includes a handle 54, which extends into the limiting seat 51 and connects to the limiting block 52. The handle 54 is used to drive the limiting block 52 away from the movable plate 20 and release the limiting effect on the movable plate 20. Furthermore, the handle 54 can abut against the limiting seat 51 to limit the travel of the limiting block 52 as it extends out of the limiting seat 51. In other words, this embodiment allows for manual release of the limiting block 52 from the movable plate 20 via the handle 54, facilitating operation and creating conditions for the subsequent reuse of the pressing device 100. Here, an elastic element 53 is fitted onto the part of the handle 54 located within the limiting seat 51. The elastic element 53 can specifically be configured as a spring, sleeve, etc.

[0055] like Figure 1 , Figure 2 As shown, in one embodiment, the pressing device 100 further includes a telescopic drive member 60, which is connected to the lower pressing block 40 for pushing the lower pressing block 40 to press down the aluminum housing 200. This further reduces the labor intensity of workers and facilitates their operation. Here, the telescopic drive member 60 can specifically be a hydraulic cylinder, an electric push rod, a linear motor, etc., which will not be described in detail here.

[0056] In this embodiment, the press-fitting device 100 also includes a pressure sensor (not shown). The pressure sensor is mounted on the lower press block 40 and electrically connected to the telescopic drive member 60. It is used to detect the pressure value when the lower press block 40 presses down on the aluminum housing 200 and generate a feedback signal. The feedback signal is used to control the operation of the telescopic drive member 60. In other words, this embodiment can use the pressure value measured by the pressure sensor when the lower press block 40 presses down to control the operation of the telescopic drive member 60. This allows for control of the pressure value when the lower press block 40 presses down on the aluminum housing 200 to meet the usage requirements of assembling the aluminum housing 200 on the high-voltage connector 400.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
