Description

Technical Field

[0001] This invention relates to the field of mechanical assembly technology, and more specifically to an assembly device for interference fit assembly of parts. Background Technology

[0002] An interference fit relies on the interference amount between the mating parts after assembly to achieve a tight connection. After assembly, the elastic deformation of the materials creates pressure between the mating surfaces. This connection structure is simple and can withstand torque, axial force, or a combination of both, resulting in high reliability.

[0003] In existing technologies, interference-fit parts are typically assembled using hammering or press-fitting methods, which can easily damage the parts and are only suitable for assembling metal parts. For example, the assembly of earphone heads and stems usually involves one-piece injection molding, splicing two halves, or nesting. One-piece injection molding requires high standards for material uniformity and mold design. Nesting methods generally use clearance fits followed by sealing with sealant, or use sealing rings. However, sealant and sealing ring connections are prone to loosening, unstable sealing, and poor connection reliability. Furthermore, existing pressure-fitting devices for earphone heads and stems have low assembly precision and are prone to damaging the parts. Summary of the Invention

[0032] Example

[0033] This embodiment provides an assembly device for interference fit assembly of parts. The assembly device is used to deform the original clearance fit parts, including an enclosing part and an enclosed part, by applying pressure to the enclosing part through a pressing mechanism. After deformation, the inner diameter of the enclosing part meets the preset size of the interference fit. Then, the enclosed part and the enclosing part are assembled to complete the interference fit connection of the parts.

[0034] like Figure 1 As shown, the assembly device in this embodiment includes a pressing mechanism 1, a pressure platform 2, and a pushing mechanism 3. The pressure platform 2 is used to place the containing component 4. The pressing mechanism 1 includes a first driving component 11 and a pressure head 12. The first driving component 11 is connected to the pressure head 12. The first driving component 11 is used to drive the pressure head 12 to move toward the pressure platform 2 to apply pressure to the containing component 4 and deform it. The pushing mechanism 3 is used to push the contained component 5 to assemble with the containing component 4.

[0035] In this embodiment, the pressing mechanism 1 is disposed above the pressure platform 2. The first driving component 11 of the pressing mechanism 1 drives the pressing head 12 to move vertically relative to the pressure platform 2. The first driving component 11 includes a driving end 111, which is connected to the pressing head 12. The driving end 111 is used to drive the pressing head 12 to reciprocate linearly relative to the pressure platform 2. In this embodiment, the pressing mechanism 1 applies pressure to the containing member 4 through the pressing head 12, causing the containing member 4 to deform and meet the preset size for interference fit with the contained member 4, that is, after deformation, the inner diameter of the containing member 4 in the pressure direction is smaller than the diameter of the contained member 4.

[0036] In some embodiments, the first drive assembly 11 can be a cylinder, a hydraulic cylinder, or an electric actuator, and the drive end 111 is a piston end that performs reciprocating linear motion within the cylinder. Driven by the first drive assembly 11, the piston end drives the pressure head 12 to reciprocate linearly. In this embodiment, the first drive assembly 11 is an adjustable-stroke single-axis cylinder or a multi-axis cylinder, and the piston end of the cylinder is connected to the pressure head 12 via a connecting plate. In this embodiment, the first drive assembly 11 has an adjustable stroke, a compact structure, effectively saves installation space, and has its own guiding function and high output force.

[0037] Specifically, in some embodiments, a first pressure detection mechanism 13 is provided between the drive end 111 and the pressure head 12. The first pressure detection mechanism 13 is used to detect the pressure applied by the pressure head 12 to the containment member 4. In this embodiment, as shown... Figure 2 and 3 As shown, the first pressure detection mechanism 13 includes a first mounting plate 131, a pressure sensor 132, and a second mounting plate 133 connected in sequence. The first mounting plate 131 is fixedly connected to the drive end 111, and the second mounting plate 133 is fixedly connected to the pressure head 12. The second mounting plate 133 has a mounting groove 134, and the pressure sensor 132 is disposed within the mounting groove 134. The pressure sensor 132 can be a strain gauge, piezoresistive, capacitive, piezoelectric, or inductive pressure sensor. When the pressure applied to the containment member 4 by the pressing mechanism 1, detected by the pressure sensor 132, reaches the first pressure threshold, the pressing mechanism 1 is controlled to stop applying pressure. The first pressure detection mechanism 13 allows for real-time adjustment of the pressing amount by the pressing mechanism 1 based on the pressure value detected by the pressure sensor 132, ensuring that the pressure applied to the containment member 4 remains within the set range, thus preventing excessive deformation of the containment member or damage to the containment member. The first pressure threshold is a safety pressure value set according to the preset deformation of the containment member.

[0038] Specifically, such as Figure 4As shown, the pressure head 12 includes a lower pressure surface 121. In some embodiments, the lower pressure surface 121 is configured as an arcuate surface that mates with the surface of the containment member 4. The arcuate lower pressure surface increases the contact area between the lower pressure surface 121 and the surface of the containment member, which helps to increase the force-bearing area of ​​the containment member, making the force uniform and preventing the problem of surface crushing caused by force concentration.

[0039] Specifically, the pressure plate 2 is provided with a fixing groove 21, the depth of which is less than the inner diameter of the containing member 4. The containing member 4 is placed in the fixing groove 21, and the pressing mechanism 1 applies pressure to the portion of the containing member 4 that extends above the fixing groove 21. After being pressed, the containing member 4 will undergo slight deformation, and the inner diameter of the containing member 4 will decrease in the same direction as the pressure direction, so that the inner diameter of the containing member 4 meets the preset size for interference fit with the contained member.

[0040] Specifically, the pushing mechanism 3 is used to push the contained component 5 and the containing component 4 together for assembly. For example... Figure 5 and 6 As shown, the pushing mechanism 3 includes a pushing part 31 and a fixing part 32 arranged at intervals. The pushing part 31 is movable relative to the fixing part 32. In this embodiment, the fixing part 32 is used to place the enclosed member 5, and the pushing part 31 moves toward the fixing part 32 and pushes the enclosed member 5, so that the enclosed member 5 and the enclosing member 4 are in an interference fit.

[0041] Specifically, the pushing mechanism 3 includes a second driving component 33 and a slide rail component 34. The output end of the second driving component 33 is connected to the pushing part 31, and the slide rail component 34 is slidably connected to the pushing part 31. The second driving component 33 is used to drive the pushing part 31 to move along the slide rail component 34.

[0042] In this embodiment, the second drive assembly 33 includes a drive motor and a lead screw shaft. The drive motor is connected to the lead screw shaft, and the lead screw shaft is connected to the output end. In this embodiment, the output end of the second drive assembly 33 is a transmission nut connected to the lead screw shaft. The drive motor drives the lead screw shaft to rotate, causing the transmission nut to reciprocate linearly along the lead screw shaft. In this embodiment, the pusher 31 is fixedly connected to the transmission nut. In some embodiments, multiple balls are provided between the lead screw shaft and the transmission nut, and the second drive assembly 33 is a ball screw drive assembly, which has the advantages of low friction coefficient, low driving torque, high precision, and high efficiency.

[0043] In some embodiments, the pushing part 31 is slidably connected to the slide rail assembly 34, the slide rail assembly 34 including at least one track 341, and the pushing part 31 is slidably connected to the track 341. The track direction of the track 341 is parallel to the movement direction of the output end of the second drive assembly 33. In this embodiment, as... Figure 5As shown, the slide rail assembly 34 includes two tracks 341 and two slide rail platforms 342. The two tracks 341 are respectively fixed on the slide rail platforms 342, and the two tracks 341 are respectively arranged parallel to each other on both sides of the lead screw shaft. In some embodiments, the slide rail assembly 34 also includes an intermediate track 343, which is arranged parallel to each other above the lead screw shaft. In this embodiment, the second drive assembly 33 and the slide rail assembly 34 are configured to reduce friction in the pushing part 31, make the movement smoother, and improve positioning accuracy.

[0044] Specifically, the pushing unit 31 includes a moving platform 311 and a moving frame 312. The moving platform 311 is slidably connected to the slide rail assembly 34. One end of the moving frame 312 is connected to the moving platform 311, and the other end of the moving frame 312 is provided with a push rod 313, which can push the contained member 5 to move. Preferably, the axis of the push rod 313 and the axis of the contained member 5 are on the same straight line.

[0045] In some embodiments, the movable platform 311 is provided with a sliding groove, which is connected to the track 341 of the slide rail assembly 34. The sliding groove makes the sliding of the movable platform 311 smoother and prevents the movable platform 311 from slipping off. In this embodiment, the movable frame 312 is vertically arranged on the movable platform 311. One end of the movable frame 312 is fixedly connected to the movable platform 311, and the other end of the movable frame 312 is provided with a mounting platform 3121. The mounting platform 3121 is provided with a push rod connecting seat 3122, which is connected to the push rod 313. The mounting platform 3121 can be fixedly connected to the push rod connecting seat 3122 or integrally formed. In some embodiments, the mounting platform 3121 is also provided with a push rod support seat 3123, through which the push rod 313 passes. The push rod support seat 3123 is used to support and fix the push rod 313, making the push rod 313 more stable.

[0046] Specifically, in some embodiments, a second pressure detection mechanism 35 is provided on the movable frame 312, and the second pressure detection mechanism 35 is connected to the push rod 313. In this embodiment, the second pressure detection mechanism 35 is fixed to the movable frame 312 via a push rod connecting seat 3122, and the second pressure detection mechanism 35 is used to detect the magnitude of the pushing force applied by the push rod 313 to the contained member 5. In this embodiment, the second pressure detection mechanism 35 can be a strain gauge, piezoresistive, capacitive, piezoelectric, or inductive pressure sensor. One end of the second pressure detection mechanism 35 is connected to the push rod connecting seat 3122, and the other end of the second pressure detection mechanism 35 is connected to the push rod 313. When the push rod 313 pushes the contained member 5 to move, the second pressure detection mechanism 35 is used to detect the magnitude of the pushing force of the push rod 313 on the contained member 5 in real time. When the pushing force applied by the push rod 313 on the contained member 5 reaches a second pressure threshold, the pushing part 31 is controlled to stop pushing. The second pressure threshold is set based on the safe pressure value of the push rod 313 on the contained part 5 when the push rod 313 pushes the contained part 5 and the contained part 4 to complete the interference fit assembly. The second pressure detection mechanism 35 can detect the magnitude of the pushing force of the push part 31 on the contained part 5 in real time. By controlling the magnitude of the pushing force, the movement of the push part 31 can be controlled, thereby controlling the amount of push-in of the contained part 5, confirming whether the interference fit assembly of the contained part 5 and the contained part 4 is reasonable, and avoiding problems such as incomplete assembly or excessive push-in.

[0047] Specifically, such as Figure 5 As shown, the fixing part 32 includes a fixing platform 321 and a fixing frame 322. The fixing platform 321 is disposed at one end of the slide rail assembly 34, and one end of the fixing frame 322 is connected to the fixing platform 321. The other end of the fixing frame 322 is provided with a clamping part 323. In this embodiment, the fixing platform 321 is fixedly disposed at one end of the slide rail assembly 34 near the pressure plate 2. The fixing frame 322 is vertically disposed on the fixing platform 321, and the clamping part 323 is used to clamp the contained member 5. When the moving platform 311 moves along the track 341 toward the fixing platform 321, the push rod 313 pushes the contained member 5 to move.

[0048] In some implementations, such as Figure 6 and 7 As shown, a limiting block 324 is provided on the side of the clamping part 323, and the limiting block 324 is connected to the clamping part 323 through a limiting connector 325.

[0049] Specifically, in some embodiments, the limiting connector 325 can be a locking screw, fastening bolt, or other component that allows adjustment of the distance between the limiting block 324 and the clamping portion 323 by adjusting the tightness of the limiting connector 325. The limiting connector 325 passes through the limiting block 324 and is adjustablely connected to the clamping portion 323. The clamping force of the limiting block 324 on the contained member 5 can be controlled by the limiting connector 325, thereby adjusting the axial position of the contained member 5. In other embodiments, the limiting connector 325 includes an elastic element and a locking element. One end of the elastic element abuts against the clamping portion 321, and the other end of the elastic element is connected to the limiting block 324 or the locking element. The elastic element can be a spring, leaf spring, or other elastic component, and the locking element can be a locking screw, pin, or fastening bolt that cooperates with the elastic element for locking. The clamping force of the limiting block 324 on the contained member 5 can be adjusted by the locking element and the elastic element. In this embodiment, the position of the enclosed part 5 can be adjusted by the limiting block 324 so that the axis of the enclosed part 5 and the axis of the enclosing part are on the same straight line, thus achieving the alignment requirement.

[0050] The assembly process of interference fit assembly of parts using the assembly device of this embodiment is as follows: The housing 4 is placed into the fixed groove 21 on the pressure table 2 by manual or automatic feeding mechanism; the housing 5 is placed on the clamping part 323 on the fixing part 32, and the position of the housing 5 is adjusted by adjusting the clamping force of the limiting block 324 on the housing 5 so that the axis of the housing 5 and the housing 4 are on the same straight line; the pressing mechanism 1 is controlled to apply pressure to the housing 4, and the pressure of the pressing mechanism 1 on the housing 4 is detected in real time by the first pressure detection mechanism 13. When the first pressure threshold is reached, the pressing mechanism 1 is controlled to stop applying pressure; the pushing mechanism 3 is controlled to push the housing 5 into the housing 4. When the pressure detected by the second pressure detection mechanism 35 reaches the second pressure threshold, the pushing mechanism 3 is controlled to stop pushing; the pressing mechanism 1 and the pushing mechanism 3 are controlled to return to the reset position and the assembled part is removed.

[0051] In this embodiment, when the assembly device is used for interference fit assembly of the earphone head shell and the earphone stem, the assembly steps are as follows: the earphone head shell is placed into the fixing groove 21 on the pressure platform 2 by manual or automatic feeding mechanism; the earphone stem is placed on the clamping part 323 on the fixing part 32, and the position of the earphone stem is adjusted by adjusting the clamping force of the limiting block 324 on the earphone stem to align the earphone stem with the earphone head shell; the pressing mechanism 1 is controlled to apply pressure to the earphone head shell, and the pressure of the pressing mechanism 1 on the earphone head shell is detected in real time by the first pressure detection mechanism. When the first pressure threshold is reached, the pressing mechanism is controlled to stop applying pressure; the pushing mechanism 3 is controlled to push the earphone stem into the earphone head shell. When the pressure detected by the second pressure detection mechanism reaches the second pressure threshold, the pushing mechanism is controlled to stop pushing; the pressing mechanism and the pushing mechanism are controlled to return to the reset position, and the assembled earphone is removed.

[0052] In some embodiments, a sealing layer is provided on the earphone stem, the thickness of which is 0.5mm-1.5mm, and the inner diameter of the earphone head shell is larger than the diameter of the earphone stem. The assembly device of this application first applies pressure to the earphone head shell through a pressing mechanism, reducing its inner diameter in the pressure direction, and then assembles the earphone stem with the earphone head shell through a pushing mechanism. After assembly, the thickness of the sealing layer on the earphone stem is 0.2mm-0.4mm, and the earphone stem and earphone head shell satisfy an interference fit.

[0053] The pressing mechanism of this application applies pressure to the containing part, causing it to deform slightly and reduce its inner diameter to achieve an interference fit assembly size; the pushing mechanism is used to push the contained part to connect with the containing part for assembly. The assembly device can reduce the inner diameter of the containing part by applying pressure to parts that do not meet the interference fit size, achieving a preset interference fit size, and further completing the assembly. The assembly steps are simple and the device is easy to operate.

[0054] The pressing mechanism of this application is equipped with a first pressure detection mechanism to monitor the pressure exerted by the pressing mechanism on the housing component. The pressure value is used to adjust the downward pressure of the pressing mechanism, ensuring that the pressure applied to the housing component remains within a set range, thus preventing excessive deformation or damage to the housing component. The pushing mechanism is equipped with a second pressure detection mechanism to monitor the pushing force of the push rod on the housing component, thereby controlling the pushing depth of the housing component and preventing incomplete assembly or over-pushing. The inclusion of the first and second pressure detection mechanisms allows the assembly device to more accurately complete the interference fit assembly of parts without damaging the product.
