Description

Technical Field

[0001] This utility model relates to the field of hearing aid technology, and in particular to a hearing aid assembly pin positioning and riveting device. Background Technology

[0002] Hearing aids are devices that provide hearing assistance to people with hearing impairments, and their casing is the main component that protects the internal functional parts. This application relates to a type of hearing aid, such as... Figure 7 As shown, its outer shell 60 includes two matching half shells. After the two half shells are snapped together, they need to be connected and fixed by 2-3 pins 61. The pins 61 are set at the edge of the two half shells and are inserted into the pin holes opened on the two half shells to achieve the assembly and fixation of the outer shell 60.

[0003] Currently, the pins are manually pressed into the pin holes using hand tools, which is a slow process and results in low production efficiency. Furthermore, due to the small size of the pins, automating the assembly process would require highly precise automated equipment, leading to higher overall automation costs. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a hearing aid assembly pin positioning and riveting device, which has the advantages of realizing rapid pin pressing, improving processing efficiency and low cost.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] According to an embodiment of this disclosure, a hearing aid assembly pin positioning and riveting device is provided, comprising:

[0007] Riveting base;

[0008] The pressing mechanism supported on the rivet base includes: a connecting arm, a pressing column slidably mounted on the connecting arm in a vertical direction, a power drive assembly for driving the pressing column to rise and move, and a rivet profile block disposed at the bottom of the pressing column for pressing pins. The pressing column is in a high position away from the rivet base under the action of the power drive assembly when it is not under force.

[0009] A positioning fixture supported on the rivet base, the positioning fixture having a positioning slot adapted to the hearing aid to be assembled;

[0010] A displacement adjustment module is disposed between the riveting base and the positioning fixture, and is used to adjust the position of the positioning fixture so that the rivet to be pressed corresponds to the riveting profile block. The displacement adjustment module is provided with several positioning structures for positioning the positioning fixture when the positioning fixture moves into place.

[0011] To achieve the above technical solution, during the riveting process, the two half-shells are first fastened together, and the pins are pre-installed in the pin holes. Then, the hearing aid to be assembled is placed in the positioning slot with the pins facing upwards. Subsequently, one of the pins is aligned with the riveting profile block by the displacement adjustment module, and the positioning structure positions the displacement adjustment module to fix the positioning fixture. The power drive component drives the pressure column to press down, which presses the pins into the pin holes through the riveting profile block. The displacement adjustment module is used to adjust the other pins to correspond with the riveting profile blocks in sequence, thus achieving the press-fitting and fixing of the rivets. The displacement adjustment module, in conjunction with the positioning structure, enables the rapid positioning of the positioning fixture, thereby achieving rapid press-fitting of the pins, improving processing efficiency, and the press-fitting operation is simple and the overall cost is lower.

[0012] In some exemplary embodiments, the displacement adjustment module includes: a first adjustment seat slidably mounted on the riveting seat along a first direction, and a second adjustment seat slidably mounted on the first adjustment seat along a second direction perpendicular to the first direction, wherein the riveting profile block is provided with a plurality of pressing surfaces that are adapted to the periphery of each pin.

[0013] To achieve the above technical solution, the position adjustment of the positioning fixture in the horizontal plane is realized through the sliding connection of the first adjusting seat and the second adjusting seat. Since the rivets are usually set near the edge of the shell, and the edge of the shell is usually an arc-shaped curved surface, different pressing surfaces can be set to match each pin, ensuring that the pin can be completely pressed into the pin hole.

[0014] In some exemplary embodiments, the positioning structure includes: a first elastic positioning member for limiting the movement position of the first adjusting seat, and a second elastic positioning member for limiting the movement position of the second adjusting seat. The bottom of the first adjusting seat is provided with a plurality of first positioning holes for the first elastic positioning member to be inserted into or disengaged to achieve positioning of the first adjusting seat. The bottom of the second adjusting seat is provided with a plurality of second positioning holes for the second elastic positioning member to be inserted into or disengaged to achieve positioning of the second adjusting seat. The first elastic positioning member is inserted into the corresponding first positioning hole, and the second elastic positioning member is inserted into the corresponding second positioning hole to achieve positioning adjustment of the positioning fixture.

[0015] To achieve the above technical solution, during the sliding process of the first adjusting seat, the first elastic positioning element can be embedded into different first positioning holes to realize the positioning adjustment of the first adjusting seat. During the sliding process of the second adjusting seat, the second elastic positioning element can be embedded into different second positioning holes to realize the positioning adjustment of the second adjusting seat. Through the positioning adjustment cooperation of the first elastic positioning element and the second elastic element, the precise positioning adjustment of the positioning fixture is realized, thereby improving the processing efficiency.

[0016] In some exemplary embodiments, the bottom of the first adjusting seat is provided with a sliding plate, the first adjusting seat is slidably mounted on the sliding plate along a first direction, and the sliding plate is detachably connected to the riveting seat.

[0017] The above technical solution enables the rapid replacement of positioning fixtures to meet the riveting and assembly requirements of hearing aids of different specifications.

[0018] In some exemplary embodiments, the second adjustment seat is provided with a fixing clip for locking and fixing to the positioning fixture.

[0019] To achieve the above technical solution, a fixing clip is set up to facilitate quick fixation or replacement of the positioning fixture, so as to adapt to the positioning needs of different sizes of hearing aids.

[0020] In some exemplary embodiments, the bottom of the pressure column is provided with a plastic buffer, and the riveting conforming block is disposed at the bottom of the plastic buffer.

[0021] The above technical solution can reduce the rigid contact between the riveting profile block and the outer shell during the riveting process by using a plastic buffer, thereby reducing damage to the outer shell during the riveting process.

[0022] In some exemplary embodiments, the power drive assembly includes: a drive gear rotatably mounted on the connecting arm, a drive rack disposed on the pressure post and meshing with the drive gear, a swing arm connected to the drive gear for driving the drive gear to rotate, and an elastic reset member sleeved on the pressure post, one end of the elastic reset member abutting against the connecting arm and the other end abutting against the top of the pressure post so that the pressure post is in a high position away from the rivet seat when not under force.

[0023] To achieve the above technical solution, the driving gear is rotated by pressing the swing arm, which in turn meshes with the driving rack to drive the pressure column downward, thus realizing the riveting action. After the riveting is completed, the swing arm is released, and the pressure column is driven to reset under the action of the elastic reset component.

[0024] In summary, compared with the prior art, this utility model has the following beneficial effects:

[0025] This utility model provides a hearing aid assembly pin positioning and riveting device, comprising: a riveting base; a pressing mechanism supported on the riveting base, the pressing mechanism including: a connecting arm, a pressing column slidably mounted on the connecting arm in a vertical direction, a power drive component for driving the pressing column to move up and down, and a riveting conforming block disposed at the bottom of the pressing column for pressing the pin, the pressing column being positioned at a high position away from the riveting base under the action of the power drive component when not under force; a positioning fixture supported on the riveting base, the positioning fixture having a positioning slot adapted to the hearing aid to be assembled; and a displacement adjustment module disposed between the riveting base and the positioning fixture for adjusting the position of the positioning fixture so that the rivet to be pressed corresponds to the riveting conforming block, the displacement adjustment module having several positioning structures for positioning the positioning fixture when it moves into place.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] like Figures 1 to 6 As shown, this utility model embodiment provides a hearing aid assembly pin positioning and riveting device, including: a riveting seat 10; a pressing mechanism 20 supported on the riveting seat 10; a positioning fixture 30 supported on the riveting seat 10, the positioning fixture 30 having a positioning slot 31 adapted to the hearing aid to be assembled; and a displacement adjustment module 40.

[0037] Specifically, the pressing mechanism 20 includes: a connecting arm 21, a pressing column 22 slidably mounted on the connecting arm 21 in the vertical direction, a power drive assembly 23 for driving the pressing column 22 to move up and down, and a riveting profile block 24 disposed at the bottom of the pressing column 22 for pressing pins. When the pressing column 22 is not under force, it is positioned at a high position away from the riveting seat 10 by the action of the power drive assembly 23.

[0038] The pressure column 22 has a sliding groove on one side, and a movable mounting part is provided on the connecting arm 21. The movable mounting part contains a slider that cooperates with the sliding groove, thereby realizing the lifting and sliding of the pressure column 22. The power drive assembly 23 includes: a drive gear 231 rotatably mounted on the connecting arm 21; a drive rack 232 disposed on the pressure column 22 and meshing with the drive gear 231; a swing arm 233 connected to the drive gear 231 for driving the drive gear 231 to rotate; and an elastic reset member 234 sleeved on the pressure column 22. One end of the elastic reset member 234 abuts against the connecting arm 21, and the other end abuts against the top of the pressure column 22 so that the pressure column 22 is in a high position away from the rivet seat 10 when it is not under force; the drive gear 231 is rotatably connected to the movable mounting part through a rotating shaft, and the drive gear 231 and the rotating shaft are relatively fixed by a key connection; the swing arm 233 is fixedly connected to the rotating shaft, so that the drive gear 231 can be directly driven to rotate through the swing arm 233; the drive rack 232 is directly formed on one side of the pressure column 22; and the elastic reset member 234 is a spring.

[0039] By pressing the swing arm 233, the drive gear 231 is rotated, which in turn meshes with the drive rack 232 to drive the pressure column 22 downward, thus realizing the riveting action. After the riveting is completed, the swing arm 233 is released, and the pressure column 22 is driven to reset under the action of the elastic reset member 234. At the same time, a plastic buffer 221 is provided at the bottom of the pressure column 22. The riveting guide block 24 is set at the bottom of the plastic buffer 221. The plastic buffer 221 has sufficient hardness and can undergo slight elastic deformation. For example, it can be made of rubber material. The plastic buffer 221 is fixed to the pressure column 22 by welding or by sleeve. The plastic buffer 221 can reduce the rigid contact between the riveting guide block 24 and the shell during the riveting process, thereby reducing the damage to the shell during the riveting process.

[0040] The displacement adjustment module 40 is disposed between the riveting seat 10 and the positioning fixture 30 and is used to adjust the position of the positioning fixture 30 so that the rivet to be pressed corresponds to the riveting profile block 24. The displacement adjustment module 40 is provided with several positioning structures to position the positioning fixture 30 when it moves into place.

[0041] Specifically, the displacement adjustment module includes: a first adjustment seat 41 slidably mounted on the riveting seat 10 along the first direction, and a second adjustment seat 42 slidably mounted on the first adjustment seat 41 along the second direction perpendicular to the first direction. The first adjustment seat 41 and the riveting seat 10, and the second adjustment seat 42 and the first adjustment seat 41 are slidably connected by a sliding rail and a sliding groove. The riveting contour block 24 is provided with a number of pressing surfaces 241 that are adapted to the outer shell area of ​​each pin.

[0042] The position adjustment of the positioning fixture 30 in the horizontal plane is realized by the sliding connection of the first adjusting seat 41 and the second adjusting seat 42. Since the rivets are usually set near the edge of the shell, and the edge of the shell is usually an arc-shaped curved surface, different pressing surfaces 241 can be set to match each pin, ensuring that the pin can be fully pressed into the pin hole.

[0043] The positioning structure includes: a first elastic positioning member 51 for limiting the movement of the first adjusting seat 41, and a second elastic positioning member 52 for limiting the movement of the second adjusting seat 42. The bottom of the first adjusting seat 41 is provided with a plurality of first positioning holes 53 for the first elastic positioning member 51 to be inserted into or detached to achieve positioning of the first adjusting seat 41. The bottom of the second adjusting seat 42 is provided with a plurality of second positioning holes 54 for the second elastic positioning member 52 to be inserted into or detached to achieve positioning of the second adjusting seat 42. The first elastic positioning member 51 is inserted into the corresponding first positioning hole 53, and the second elastic positioning member 52 is inserted into the corresponding second positioning hole 54 to achieve positioning adjustment of the positioning fixture 30. The first elastic positioning member 51 and the second elastic positioning member 52 can be bead springs or positioning beads. The first positioning hole 53 and the second positioning hole 54 are both semi-circular or arc-shaped, so that the first elastic positioning member 51 and the second elastic positioning member 52 can be inserted into the first positioning hole 53 and the second positioning hole 54 respectively for positioning, and can also detach from the first positioning hole 53 and the second positioning hole 54 after a certain force is applied.

[0044] During the sliding process of the first adjusting seat 41, the first elastic positioning member 51 can be inserted into different first positioning holes 53 to realize the positioning adjustment of the first adjusting seat 41. During the sliding process of the second adjusting seat 42, the second elastic positioning member 52 can be inserted into different second positioning holes 54 to realize the positioning adjustment of the second adjusting seat 42. Through the positioning adjustment cooperation of the first elastic positioning member 51 and the second elastic member, the precise positioning adjustment of the positioning fixture 30 is realized, thereby improving the processing efficiency.

[0045] Furthermore, a sliding plate 43 is provided at the bottom of the first adjustment seat 41. The first adjustment seat 41 is slidably mounted on the sliding plate 43 along the first direction. The sliding plate 43 is detachably connected to the riveting seat 10. The sliding plate 43 can be used as a part of the riveting seat 10, for example, by being detachably connected to the riveting seat 10 through countersunk bolts. This allows for the quick replacement of the positioning fixture 30 to meet the riveting assembly requirements of hearing aids of different specifications.

[0046] Meanwhile, a fixing clip 421 is provided on the second adjustment seat 42 for fixing to the positioning fixture 30. The fixing clip 421 can be, for example, a pin rotatably connected to the second adjustment seat 42. The second adjustment seat 42 is provided with a storage groove, and the positioning fixture 30 is placed in the storage groove. The pin rotates to press against the upper surface of the positioning fixture 30 to fix the positioning fixture 30 on the second adjustment seat 42. In some embodiments, the fixing clip 421 can also be a bolt threaded to the side of the second adjustment seat 42. The bolt abuts against the side of the positioning fixture 30 to fix the positioning fixture 30 on the second adjustment seat 42. By setting the fixing clip 421, it is convenient to quickly fix or replace the positioning fixture 30 to adapt to the positioning requirements of different hearing aids.

[0047] During the riveting process, the two half-shells are first fastened together, and the pins are pre-installed in the pin holes. Then, the hearing aid to be assembled is placed in the positioning slot 31 with the pins facing upwards. Subsequently, the displacement adjustment module 40 aligns one of the pins with the riveting profile block 24, and the positioning structure positions the displacement adjustment module 40 to fix the positioning fixture 30. The power drive component 23 drives the pressure column 22 to press down, and the pins are pressed into the pin holes by the riveting profile block 24. The displacement adjustment module 40 is used to adjust the other pins to correspond with the riveting profile block 24, thus achieving the pressing and fixing of the rivets. The displacement adjustment module 40, in conjunction with the positioning structure, enables the rapid positioning of the positioning fixture 30, thereby achieving rapid pressing of the pins, improving processing efficiency, and the pressing operation is simple and the overall cost is lower.

[0048] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
