Description

Technical Field

[0001] This application relates to the field of press-fitting technology, specifically to a press-fitting device that can prevent overload of the force detector. Background Technology

[0002] Press fitting is an assembly process that uses pressure to achieve a tight fit between parts, commonly used in industries such as machinery manufacturing and automobiles. During press fitting, most mechanisms are equipped with pressure sensors to accurately detect changes in the pressing force.

[0003] However, pressure sensors installed in press-fitting mechanisms are mostly in direct contact with rigid press-fitting components. During the press-fitting operation, these components may become stuck or obstructed. If this happens, the pressure sensor will gradually be subjected to pressure exceeding its measuring range, which could potentially overload and damage the sensor. Consequently, a damaged pressure sensor cannot accurately detect changes in press-fitting force. Utility Model Content

The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

[0025] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application 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, the above terms should not be construed as limitations on this application.

[0026] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0027] refer to Figure 1 The pressure fitting device for preventing force detector overload according to a preferred embodiment of the present application will be described in detail below. The pressure fitting device for preventing force detector overload includes a device body 10, a pressure fitting component 20 and a force detection component 30.

[0028] Specifically, the pressing assembly 20 includes a drive unit 21, a passive block 22, a loading shaft 23, and a pressing shaft 24, wherein the drive unit 21 is mounted on the device body 10. The passive block 22 is drivably connected to the drive unit 21, and the passive block 22 is moved relative to the pressing shaft 24 by being driven by the drive unit 21. The loading shaft 23 is mounted on the device body 10, and a loading portion 231 is formed on the outer wall of the other end of the loading shaft 23 away from the device body 10 for assembling a product 90. The pressing shaft 24 is slidably connected to the loading shaft 23.

[0029] The force detection assembly 30 includes a force detection unit 31 and a spring member 32, wherein the force detection unit 31 is connected to the passive block 22 and is located between the passive block 22 and the pressure shaft 24. The spring member 32 defines an abutment portion and a deformation portion connected to the abutment portion, and the abutment portion is disposed between the force detection unit 31 and the pressure shaft 24. When the drive unit 21 drives the passive block 22 closer to the pressure shaft 24, the force detection unit 31 abuts against the abutment portion of the spring member 32, and the deformation portion of the spring member 32 tends to deform and drive the pressure shaft 24, so that the pressure shaft 24 slides along the axial direction of the loading shaft 23 to push the product 90 assembled on the loading part 231.

[0030] Those skilled in the art will understand that when the drive unit 21 is activated to drive the passive block 22 to move toward the pressure shaft 24, the force detection unit 31 moves along with the passive block 22 to press against the abutment portion of the spring member 32, so that the deformable portion of the spring member 32 tends to deform. At this time, under the action of force transmission, the pressure shaft 24 is pushed against the product 90 by the action of the spring member 32 along the axial direction of the loading shaft 23. In this process, the force detection unit 31 normally detects the magnitude of the transmitted force on the pressure shaft 24.

[0031] When the pressure shaft 24 gets stuck or obstructed during the process of pressing the product 90, the deformable part of the spring member 32 gradually deforms as the abutment part is pressed by the force detection unit 31, so that the pressure of the force detection unit 31 pressing the abutment part can continue to be released, thereby protecting the force detection unit 31 and preventing the force detection unit 31 from being directly overloaded by the pressure generated by the drive unit 21 driving the passive block 22 to move.

[0032] Preferably, the force detection unit 31 is implemented to include a pressure sensor.

[0033] In one embodiment, the spring member 32 is made of an elastic material, and one end of the spring member 32 is connected to the pressure shaft 24, while the other end of the spring member 32 away from the pressure shaft 24 is located on the movement path of the force detection unit 31.

[0034] Under normal circumstances, when the pressure shaft 24 pushes the product 90 without jamming or obstruction, the force detection unit 31 is driven to press against the spring member 32. Under the transmission of force, the spring member 32 tends to deform and drive the pressure shaft 24. However, when the pressure shaft 24 presses against the product 90 and becomes jammed or obstructed, the force detection unit 31 is driven to press against the spring member 32. At this time, the spring member 32 gradually deforms, allowing the force detection unit 31 to release the pressure pressing against the spring member 32.

[0035] In another embodiment, such as Figures 1 to 6 As shown, the rebound member 32 includes a contact block 321 and at least one elastic element 322, wherein the contact block 321 is located on the moving path of the force detection unit 31 and is configured as the abutment portion. Each elastic element 322 is disposed between the pressure shaft 24 and the contact block 321 in a compressible manner, and the two ends of each elastic element 322 in the compression direction are respectively connected to the pressure shaft 24 and the contact block 321, and each elastic element 322 is configured to form at least a portion of the deformable portion.

[0036] Under normal circumstances, when the pressure shaft 24 pushes the product 90 without jamming or obstruction, the contact block 321 is pressed against by the force detection unit 31, and each elastic element 322 tends to be compressed. At this time, due to the force transmission, the pressure shaft 24 is driven. However, when the pressure shaft 24 presses against the product 90 and becomes jammed or obstructed, the force detection unit 31 still presses against the contact block 321. At this time, under the force transmission, each elastic element 322 gradually deforms, allowing the force detection unit 31 to release the pressure pressing against the contact block 321.

[0037] It is worth mentioning that, in a modified embodiment, such as Figure 7As shown, the force detection unit 31 is disposed between the passive block 22 and the pressure shaft 24, and the force detection unit 31 is connected to the pressure shaft 24. The springback member 32 includes a contact block 321 and at least one elastic element 322, wherein the contact block 321 is configured as an abutment portion. Each elastic element 322 is disposed between the passive block 22 and the contact block 321 in a compressible manner, and the two ends of each elastic element 322 in the compression direction are respectively connected to the passive block 22 and the contact block 321, and each elastic element 322 is configured to form at least part of the deformation portion. Thus, the passive block 22 can be driven by the drive unit 21 to move the contact block 321 relative to the force detection unit 31, thereby driving the pressure shaft 24 to slide on the loading shaft 23 for pressing operation.

[0038] Preferably, the springback member 32 includes at least one connector 323, one end of each connector 323 is connected to the pressure shaft 24, and the other end of each connector 323 away from the pressure shaft 24 passes through the contact block 321 and is away from the movement path of the force detection unit 31. The contact block 321 is configured to be able to move synchronously along the axial direction of each connector 323 by being driven by the force detection unit 31, thereby preventing each elastic member 322 from deviating.

[0039] Preferably, one of the elastic elements 322 is also penetrated by the other end of the connector 323 away from the pressure shaft 24, so that when each elastic element 322 is compressed, each elastic element 322 can be compressed synchronously along the axial direction of its respective connector 323.

[0040] For example, in a preferred embodiment, such as Figures 1 to 6 As shown, the number of elastic elements 322 is set to two, and the number of connectors 323 is also set to two. The two connectors 323 are arranged at intervals, and the other ends of the two connectors 323 away from the pressure shaft 24 respectively pass through the two elastic elements 322. The other ends of the two connectors 323 away from the pressure shaft 24 are both away from the movement path of the force detection unit 31.

[0041] Preferably, each of the elastic elements 322 is configured as a spring.

[0042] Preferably, each of the connectors 323 is configured as a screw, that is, the front end of each screw passes through the contact block 321 and is connected to the pressure shaft 24, and the rear end of each screw is used to prevent the contact block 321 from disengaging.

[0043] More preferably, the force detection component 30 further includes at least one protective component 33.

[0044] It should be noted that when the compression of each elastic element 322 of the rebound member 32 is about to reach its limit and the pressure shaft 24 is still stuck and obstructed, the protective member 33 is used to further protect the force detection unit 31.

[0045] In one embodiment, each of the protective members 33 is configured as a rod, and each of the protective members 33 is disposed between the passive block 22 and the pressure shaft 24, with one end of each of the protective members 33 connected to the pressure shaft 24, and the other end of each of the protective members 33 away from the pressure shaft 24 maintaining a predetermined gap with the passive block 22, and the other end of each of the protective members 33 away from the pressure shaft 24 located on the movement path of the passive block 22.

[0046] It should be noted that when each of the elastic elements 322 is compressed to the limit, at least one of the protective members 33 abuts against the passive block 22 at the other end away from the pressure shaft 24 to prevent the force detection unit 31 from continuing to indirectly compress each of the elastic elements 322 through the contact block 321. At this time, since the passive block 22 is blocked by at least one of the protective members 33, the passive block 22 applies pressure to the pressure shaft 24 through at least one of the protective members 33. At this time, the pressure on the contact block 321 will not increase, and the reaction force on the force detection unit 31 will not increase, thereby further protecting the force detection unit 31.

[0047] In another embodiment, specifically as follows Figure 3 and Figure 4As shown, each of the protective components 33 includes a movable rod 331 and a protective rod 332. Each movable rod 331 has a feeding portion 3311 and a connecting portion 3312 connected to the feeding portion 3311. The cross-sectional diameter of the feeding portion 3311 of each movable rod 331 is larger than the cross-sectional diameter of the connecting portion 3312. The feeding portion 3311 of each movable rod 331 is slidably mounted on the pressure shaft 24, and the connecting portion 3312 of each movable rod 331 is mounted on the passive block 22. Each protective rod 332 is disposed between the passive block 22 and the pressure shaft 24, and one protective rod 332 is slidably mounted on the feeding portion 3311 of one movable rod 331. Each protective rod 332 is located away from the movement path of the force detection unit 31. The passive block 22 is driven to move each of the moving rods 331 relative to the pressure shaft 24, so as to move closer to and away from each of the guard rods 332.

[0048] Understandably, when each of the elastic elements 322 is compressed to near its limit, the passive block 22 gradually approaches each of the protective rods 332 and is blocked by each of the protective rods 332. At this time, the pressure on the contact block 321 will not increase, and the reaction force on the force detection unit 31 will not increase, thereby further protecting the force detection unit 31. In addition, the driven passive block 22 also begins to indirectly apply pressure to the pressure shaft 24 by applying pressure to each of the protective rods 332 that are blocking its own movement.

[0049] Preferably, each of the protective components 33 further includes a first fixing member 333 and a second fixing member 334, wherein the first fixing member 333 is configured to be detachably connected to the outer periphery of the connecting portion 3312 of a movable rod 331 to prevent the movable rod 331 from separating from the passive block 22. The second fixing member 334 is configured to be detachably connected to the moving portion 3311 of a movable rod 331 to prevent the movable rod 331 from separating from the passive block 22.

[0050] It is worth mentioning that the passive block 22 forms at least one through hole 2201, one through hole 2201 is provided for the connecting portion 3312 of one of the moving rods 331 to pass through, and the inner diameter of each through hole 2201 is smaller than the outer diameter of one of the feeding portions 3311, and the outer diameter of each of the first fixing members 333 is larger than the inner diameter of one of the through holes 2201. Correspondingly, the pressure shaft 24 forms at least one slide 2401, one slide 2401 is provided for the feeding portion 3311 of one of the moving rods 331 to slide, and the inner diameter of one slide 2401 is smaller than the outer diameter of one of the second fixing members 334.

[0051] Preferably, each of the first fixing members 333 is configured as a nut. Each of the second fixing members 334 is configured as a screw with a washer to prevent the moving rod 331 from disengaging from the pressure shaft 24.

[0052] In one embodiment, the drive unit 21 is configured as a telescopic cylinder with a telescopic drive end, and the passive block 22 is mounted on the drive end of the telescopic cylinder. When the telescopic cylinder is activated to extend or retract its drive end, the passive block 22 moves relative to the pressure shaft 24, following the extension and retraction of the drive end. Thus, during the pressing operation, the passive block 22 drives the force detection unit 31 to press against the contact block 321 of the springback member 32.

[0053] In another embodiment, the drive unit 21 includes a drive member 211 and a transmission member 212, wherein the drive member 211 is mounted on the device body 10 and is used to drive the transmission member 212. The transmission member 212, driven by the drive member 211, causes the passive block 22 to move relatively closer to and away from the pressure shaft 24.

[0054] Preferably, the drive element 211 is implemented as a drive motor with a coupling.

[0055] Preferably, such as Figure 1 , Figure 3 and Figure 5As shown, the transmission component 212 includes a screw 2121, a slider 2122, and a guide rail 2123. The screw 2121 is synchronously rotatably connected to the driving component 211, and the screw 2121 is connected to the slider 2122 via a threaded connection. The slider 2122 is slidably mounted on the guide rail 2123. The guide rail 2123 is connected to the device body 10, and the extending direction of the guide rail 2123 is consistent with the moving direction of the slider 2122, thereby limiting the moving direction of the slider 2122. The passive block 22 is mounted on the slider 2122.

[0056] Understandably, when the drive unit 211 is activated to drive the screw 2121, the screw 2121 is driven to rotate along its own axis. Since the screw 2121 is connected to the slider 2122 by a threaded connection, and the slider 2122 is slidably mounted on the guide rail 2123, the slider 2122 is limited and can only move along the extension direction of the guide rail 2123. At this time, the passive block 22 moves synchronously with the slider 2122 to drive the force detection unit 31.

[0057] Preferably, the device body 10 is provided with a first mounting portion 11, and the driving member 211 is mounted on the first mounting portion 11 of the device body 10.

[0058] Preferably, such as Figure 1 , Figure 3 and Figure 5 As shown, the device body 10 also includes a second mounting portion 12 and a third mounting portion 13, wherein the second mounting portion 12 and the third mounting portion 13 are arranged opposite to each other and spaced apart. Preferably, the top of the second mounting portion 12 forms a T-shaped groove 1201 extending downwards for mounting the other end of the loading shaft 23 away from the loading portion 231. The top of the third mounting portion 13 forms a passage 1301. The loading shaft 23 is mounted in the passage 1301, and the loading portion 231 of the loading shaft 23 passes through the third mounting portion 13 by passing through the passage 1301. The pressing shaft 24 can also be slidably mounted in the passage 1301.

[0059] In addition, the pressure fitting device that can prevent overload of the force detector also includes a monitoring component 40.

[0060] Preferably, the monitoring component 40 includes a monitor 41 and a monitored element 42, wherein the monitor 41 is mounted on one side of the device body 10 and forms a monitoring channel 4101. One end of the monitored element 42 is mounted to the slider 2122, and the other end of the monitored element 42 away from the slider 2122 forms a monitored portion 421, which is located in the monitoring channel 4101. When the slider 2122 moves on the guide rail 2123, the monitored element 42 is driven, causing the monitored portion 421 to move within the monitoring channel 4101.

[0061] It should be noted that the monitor 41 has two monitoring positions set in the monitoring channel 4101, corresponding to the initial position of the slider 2122 before it moves and the final position of the slider 2122 after it moves, respectively. The monitored part 421 of the monitored component 42 can follow the movement of the slider 2122 and pass through these two monitoring positions. When the monitored part 421 of the monitored component 42 passes through these two monitoring positions, the monitor 41 will send a specific signal to the control terminal, so that the control terminal, upon receiving the signal, will correspondingly control the drive unit 21 to drive the action of the passive block 22.

[0062] For example, when the slider 2122 moves to the end position, the drive unit 21 will be controlled to stop driving the pressure shaft 24 to move in front of the loading shaft 23 (in the direction of the loading part 231). At this time, the vertical distance between the passive block 22 and the loading shaft 23 reaches its minimum. When the slider 2122 moves to the initial position, the drive unit 21 will also be controlled to stop driving the pressure shaft 24 to move behind the loading shaft 23 (away from the loading part 231). At this time, the vertical distance between the passive block 22 and the loading shaft 23 reaches its maximum.

[0063] Preferably, the monitor 41 is implemented including an infrared sensor.

[0064] Those skilled in the art should understand that the embodiments of this application described above and shown in the accompanying drawings are merely examples and do not limit the scope of this application. The advantages of this application have been fully and effectively implemented. The functional and structural principles of this application have been demonstrated and explained in the embodiments, and any variations or modifications can be made to the implementation of this application without departing from the stated principles.
