[0015] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0018] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] The following is for reference. Figure 1 A device 100 for picking up a cup-shaped plug according to an embodiment of the present invention is described, wherein the cup-shaped plug is installed inside a workpiece and the cup-shaped plug has a through hole, and the device 100 includes: Mounting rod 10 extends along a first direction. One end of mounting rod 10 has a limiting part 11. Mounting rod 10 is fitted into the through hole of cup-shaped plug, and the limiting part 11 is in limiting cooperation with cup-shaped plug. The support structure 20 is sleeved on the mounting rod 10. The support structure 20 is used to abut against the surface of the workpiece, and the mounting rod 10 is movable relative to the support structure 20 in a first direction to remove the cup-shaped plug from the workpiece.

[0020] The cup-shaped plug is installed inside the workpiece. A drill bit is used to drill a hole in the leaking cup-shaped plug on the workpiece (which can be a motor housing or other parts) so that the cup-shaped plug has a through hole. The workpiece can be fixed by a pressing mechanism to fix the cup-shaped plug to be removed. Then, the cup-shaped plug is removed by the picking device 100.

[0021] The retrieving device 100 includes: a mounting rod 10, which can be modified from a threaded rod with a bolt head, such as... Figure 1As shown, the X-direction is the first direction, and the mounting rod 10 extends along this direction. One end of the mounting rod 10 has a limiting part 11, which can be modified from the bolt head of the mounting rod 10. The limiting part 11 can be constructed as a rectangular block. The limiting part 11 and the mounting rod 10 together form a "T"-shaped or similar "T"-shaped hook. The length of the limiting part 11 is greater than the diameter of the through hole of the cup-shaped plug, and the length of the limiting part 11 is less than the outer diameter of the cup-shaped plug. When the mounting rod 10 is assembled into the through hole of the cup-shaped plug, the limiting part 11 engages with the cup-shaped plug to hook it. Because the length of the limiting part 11 is greater than the diameter of the through hole of the cup-shaped plug, the cup-shaped plug will not fall off the limiting part 11 when the mounting rod 10 is placed perpendicular to the cup-shaped plug. Furthermore, because the length of the limiting part 11 is less than the outer diameter of the cup-shaped plug, the limiting part 11 will not contact the inner wall of the workpiece, thereby greatly reducing the risk of damaging the workpiece.

[0022] The support structure 20 can be constructed as a nylon sleeve, which is fitted onto the mounting rod 10. The end wall of the support structure 20 near the limiting part 11 is used to abut against the workpiece surface to support the mounting rod 10. The nylon sleeve construction of the support structure 20 provides stable support while maximizing the protection of the workpiece and reducing noise and cost. Nylon material is softer and has good elasticity and toughness. When the support structure 20 abuts against the workpiece, it will not cause scratches, indentations, or abrasions on the workpiece surface. Furthermore, the nylon sleeve will undergo slight deformation under pressure, thereby increasing the contact area, dispersing the concentrated force into a distributed force, avoiding stress concentration, and further preventing workpiece deformation or surface damage.

[0023] The mounting rod 10 is movable relative to the support structure 20 in the first direction. When the mounting rod 10 moves toward the cup-shaped plug, the limiting part 11 can be inserted into the through hole of the cup-shaped plug and engage with the cup-shaped plug. When the mounting rod 10 is perpendicular to the cup-shaped plug and the limiting part 11 engages with the cup-shaped plug, the mounting rod 10 moves away from the limiting part 11 in the first direction, and the cup-shaped plug can be removed from the workpiece.

[0024] It can be explained that the mounting rod 10 can be moved along the first direction by manual drive, or other drive components can be set to drive the mounting rod 10 to move along the first direction. The settings can be made reasonably according to the actual situation.

[0025] With the limiting part 11 engaging with the cup-shaped plug, the mounting rod 10 moves relative to the support structure 20 in the first direction, allowing the cup-shaped plug to be easily removed from the workpiece without prying or impacting it, thus reducing damage to the workpiece. Furthermore, the limiting part 11 engaging with the cup-shaped plug prevents the cup-shaped plug from falling off during the removal process, thereby improving the success rate and efficiency of removing the cup-shaped plug without damaging the workpiece and reducing the cost of removing the cup-shaped plug.

[0026] According to some embodiments of the present invention, such as Figure 1 As shown, the picking device 100 may further include: a positioning structure 30, which is fixed to the outer peripheral wall of the mounting rod 10, and a support structure 20 is sleeved on the positioning structure 30. The positioning structure 30 can drive the mounting rod 10 to move synchronously relative to the support structure 20 in a first direction.

[0027] The positioning structure 30 is fixed to the outer peripheral wall of the mounting rod 10. In some embodiments of the present invention, the positioning structure 30 and the mounting rod 10 can be integrally formed, or the positioning structure 30 and the mounting rod 10 can be welded together. However, the present invention is not limited to these methods, and the positioning structure 30 and the mounting rod 10 can also be fixedly connected in other ways, as long as the positioning structure 30 is fixed to the outer peripheral wall of the mounting rod 10. In a specific embodiment of the present invention, the positioning structure 30 can be located in the middle of the mounting rod 10, and the cross-sectional shape of the positioning structure 30 and the mounting rod 10 are concentric circles.

[0028] The support structure 20 is fitted onto the positioning structure 30, and the positioning structure 30 can drive the mounting rod 10 to move synchronously relative to the support structure 20 along the first direction. The mounting rod 10 can be moved synchronously relative to the support structure 20 along the first direction by manually driving the positioning structure 30 to move along the first direction, or other driving components can be set to drive the positioning structure 30 to move along the first direction to move synchronously relative to the support structure 20 along the first direction. The settings can be made reasonably according to the actual situation.

[0029] Furthermore, the positioning structure 30 may include a first positioning part 33 and a second positioning part 34. Both the first positioning part 33 and the second positioning part 34 are constructed in a columnar shape. The first positioning part 33 and the second positioning part 34 are arranged along a first direction. Both the first positioning part 33 and the second positioning part 34 are collinear with the central axis of the mounting rod 10. The second positioning part 34 is connected between the first positioning part 33 and the mounting rod 10. The first positioning part 33 and the support structure 20 are in clearance fit, which enables the central axis of the mounting rod 10 and the central axis of the support structure 20 to be collinear. The positioning structure 30 can guide the mounting rod 10 when it moves along the first direction within the support structure 20, so as to avoid the mounting rod 10 from deviating when it moves along the first direction. This ensures that the mounting rod 10 is perpendicular to the cup-shaped plug, so as to prevent the cup-shaped plug from separating from the limiting part 11. This reduces the risk of the cup-shaped plug falling during the picking process, and improves the success rate and efficiency of picking up the cup-shaped plug.

[0030] Furthermore, the outer diameter of the second positioning part 34 is slightly smaller than the diameter of the through hole of the bowl-shaped plug. When assembling the limiting part 11 and the bowl-shaped plug, the limiting part 11 is lowered into the through hole of the bowl-shaped plug by tilting the picking device 100. After the limiting part 11 extends into the through hole of the bowl-shaped plug, the picking device 100 is perpendicular to the bowl-shaped plug, and the second positioning part 34 is extended into the bowl-shaped plug to adjust the position of the mounting rod 10. Since the second positioning part 34 and the bowl-shaped plug are in clearance fit, the mounting rod 10 is ensured to be perpendicular to the bowl-shaped plug, thereby ensuring that the limiting part 11 and the bowl-shaped plug are limited. When the mounting rod 10 is moved along the first direction, the limiting part 11 and the bowl-shaped plug will not separate, thereby reducing the risk of the bowl-shaped plug falling during the picking process, and further improving the success rate and efficiency of picking the bowl-shaped plug.

[0031] The gap between the first positioning part 33 and the support structure 20 can be 0.1mm-0.3mm. For example, the gap between the first positioning part 33 and the support structure 20 can be 0.1mm, 0.15mm, 0.2mm, 0.3mm, etc. However, the present invention is not limited to this, and the gap range can also be other values ​​within 0.1mm-0.3mm, as long as the gap range between the first positioning part 33 and the support structure 20 can be 0.1mm-0.3mm. This setting facilitates the movement of the positioning structure 30 along the first direction within the support structure 20 without causing it to wobble within the support structure 20. This further ensures that the mounting 10 is perpendicular to the cup-shaped plug, preventing the cup-shaped plug from separating from the limiting part 11, thereby reducing the risk of the cup-shaped plug falling during the removal process, and improving the success rate and efficiency of removing the cup-shaped plug.

[0032] According to some embodiments of the present invention, such as Figure 1 As shown, the picking device 100 also includes: an operating rod 31, a support structure 20 having a mounting hole 21 opposite to the outer peripheral wall of the positioning structure 30, the operating rod 31 passing through the mounting hole 21 and fixed to the positioning structure 30, and the operating rod 31 being movable relative to the support structure 20 along a first direction.

[0033] The support structure 20 has a mounting hole 21 opposite to the outer peripheral wall of the positioning structure 30. The operating rod 31 passes through the mounting hole 21 and is fixed to the positioning structure 30. The operating rod 31 and the positioning structure 30 can be connected by threads or by snap-fit ​​connection. However, the present invention is not limited to this. The operating rod 31 and the positioning structure 30 can also be connected by other means, as long as the operating rod 31 is fixed to the positioning structure 30.

[0034] The operating lever 31 is perpendicularly connected to the outer peripheral wall of the positioning structure 30. The operating lever 31 passes through the mounting hole 21 and can move relative to the support structure 20 along the first direction within the mounting hole 21. The arrangement of the operating lever 31 and the mounting hole 21 limits the travel of the mounting rod 10, preventing it from falling off the support structure 20 during the use of the picking device 100. The mounting hole 21 can extend along the first direction, and its extension length can be reasonably set according to the size of the picking device 100 and the position of the cup-shaped plug. The operating lever 31 can move relative to the support structure 20 along the first direction. By changing the position of the operating lever 31 in the mounting hole 21, it is possible to determine whether the assembly of the limiting part 11 and the cup-shaped plug is in place, thereby reminding the operator to proceed to the next picking step. This effectively shortens the picking time of the cup-shaped plug and improves the picking efficiency.

[0035] According to some embodiments of the present invention, such as Figure 1 As shown, the peripheral wall of the positioning structure 30 has a threaded hole 32 corresponding to the mounting hole 21. The mounting hole 21 is a strip-shaped hole extending along the first direction. The operating rod 31 is detachably assembled into the threaded hole 32.

[0036] When the positioning structure 30 is inserted into the support structure 20, the threaded hole 32 of the positioning structure 30 is aligned with the mounting hole 21 of the support structure 20, and the operating rod 31 is assembled into the threaded hole 32. By moving the operating rod 31 in the mounting hole 21, the position of the mounting rod 10 can be determined, and thus the assembly of the limiting part 11 and the cup-shaped plug can be determined, so as to remind the operator to proceed to the next picking step. This can effectively shorten the picking time of the cup-shaped plug and thus improve the picking efficiency of the cup-shaped plug.

[0037] According to some embodiments of the present invention, the peripheral wall of the positioning structure 30 is formed with at least one threaded hole 32, and the support structure 20 is formed with at least one mounting hole 21, wherein the mounting hole 21 and the threaded hole 32 are provided in a one-to-one correspondence.

[0038] The peripheral wall of the positioning structure 30 is provided with at least one threaded hole 32. In some embodiments of the present invention, the peripheral wall of the positioning structure 30 may be provided with one, two, three or more threaded holes 32. However, the present invention is not limited to this. The peripheral wall of the positioning structure 30 may also be provided with other numbers of threaded holes 32, as long as the peripheral wall of the positioning structure 30 is provided with at least one threaded hole 32.

[0039] The support structure 20 has at least one mounting hole 21. In some embodiments of the present invention, the peripheral wall of the support structure 20 may have one, two, three, or other mounting holes 21. However, the present invention is not limited to this, and the peripheral wall of the support structure 20 may also have other numbers of mounting holes 21, as long as the peripheral wall of the support structure 20 has at least one mounting hole 21. The mounting holes 21 are provided in a one-to-one correspondence with the threaded holes 32, so that the operating rod 31 is installed in the corresponding threaded hole 32. The present invention is described with an example in which the peripheral wall of the positioning structure 30 has one threaded hole 32 and the support structure 20 has one mounting hole 21. This arrangement can reduce the number of parts in the picking device 100, thereby reducing the assembly time of the picking device 100 and improving the picking efficiency of the cup-shaped plug.

[0040] According to some embodiments of the present invention, such as Figure 1 As shown, the taking device 100 also includes: a nut 50, a threaded rod segment 12 formed at the end of the mounting rod 10 away from the limiting part 11, an external thread formed on the peripheral wall of the threaded rod segment 12, the nut 50 being threadedly connected to the threaded rod segment 12, and the mounting rod 10 being moved along the first direction by rotating the nut 50.

[0041] The mounting rod 10 extends out of the support structure 20 at one end away from the limiting part 11, and a threaded rod segment 12 is formed at the other end of the mounting rod 10 away from the limiting part 11. The peripheral wall of the threaded rod segment 12 is formed with external threads. The nut 50 is threadedly connected to the threaded rod segment 12. By rotating the nut 50, the rotation can be converted into the axial movement of the mounting rod 10. During the rotation of the nut 50, the operating rod 31 moves away from the cup-shaped plug along the extension direction of the mounting hole 21, thereby enabling the mounting rod 10 to move away from the cup-shaped plug along the first direction, and thus enabling the cup-shaped plug to be pulled out by the picking device 100.

[0042] When the operating lever 31 moves to the mounting hole 21 near the end wall of the nut 50, the cup-shaped plug is pulled out of the workpiece. At this time, the picking device 100 is tilted to remove the limiting part 11 from the through hole of the cup-shaped plug, and the picking of one cup-shaped plug is completed.

[0043] According to some embodiments of the present invention, such as Figure 1 As shown, the picking device 100 may further include: a bearing housing 40 and a bearing 41. Along the first direction, the bearing housing 40 is installed at the end of the support structure 20 away from the limiting part 11, and the bearing housing 40 is fixedly connected to the support structure 20. The bearing 41 is installed inside the bearing housing 40, and the mounting rod 10 passes through the inner ring of the bearing 41.

[0044] The bearing housing 40 is installed at the end of the support structure 20 away from the limiting part 11, and the bearing housing 40 is fixedly connected to the support structure 20. In some embodiments of the present invention, the bearing housing 40 and the support structure 20 can be interference-fitted, or the bearing housing 40 and the support structure 20 can be snap-fitted. However, the present invention is not limited to this. The bearing housing 40 and the support structure 20 can also be fixedly connected in other ways, as long as the bearing housing 40 and the support structure 20 are fixedly connected.

[0045] A bearing 41 is installed inside the bearing housing 40. The bearing 41 can be a thrust bearing 41, a jack bearing 41, etc. The end of the mounting rod 10 away from the limiting part 11 passes through the inner ring of the bearing 41, and the outer diameter of the end of the mounting rod 10 away from the limiting part 11 can be matched with the inner diameter of the inner ring of the bearing 41. When the end of the mounting rod 10 away from the limiting part 11 passes through the inner ring of the bearing 41, the mounting rod 10 can be further limited, preventing the mounting rod 10 from shaking in the support structure 20. This further ensures that when the cup-shaped plug is removed, the mounting rod 10 can be perpendicular to the cup-shaped plug, so as to prevent the cup-shaped plug from separating from the limiting part 11. This reduces the risk of the cup-shaped plug falling during the removal process, thereby improving the success rate and efficiency of removing the cup-shaped plug.

[0046] Furthermore, the bearing housing 40 and bearing 41 are located between the support structure 20 and the nut 50, effectively isolating the nut 50 from the support structure 20. This prevents the rotation of the nut 50 from causing the support structure 20 to rotate, thus avoiding friction between the support structure 20 and the workpiece and reducing damage to the workpiece. It also prevents the nut 50 from contacting and rubbing against the support structure 20, further reducing damage and effectively extending the service life of the support structure 20.

[0047] According to some embodiments of the present invention, such as Figure 1 As shown, the bearing housing 40 includes a first housing 42 and a second housing 43. The first housing 42 and the second housing 43 are arranged and fixedly connected along a first direction. The support structure 20 has an assembly hole 22 that passes through the support structure 20 along the first direction. The mounting rod 10 passes through the assembly hole 22. The first housing 42 is located on the side of the second housing 43 facing the limiting part 11. The second housing 43 has an assembly space 44 for assembling the bearing 41. The first housing 42 is inserted into the assembly hole 22. The end face of the second housing 43 and the support structure 20 away from the limiting part 11 is in contact and limited.

[0048] The support structure 20 has an assembly hole 22 extending through it in a first direction. A mounting rod 10 passes through the assembly hole 22. A first seat 42 is located on the side of the second seat 43 facing the limiting part 11. The second seat 43 has an assembly space 44 for assembling the bearing 41. The first seat 42 is inserted into the assembly hole 22 and is interference-fitted with the support structure 20 to fix the bearing seat 40 to the support structure 20. The bearing 41 is installed in the assembly space 44 of the second seat 43. The end faces of the second seat 43 and the support structure 20 facing away from the limiting part 11 are in contact and limited to prevent the bearing seat 40 from falling into the assembly hole 22 of the support structure 20. The arrangement of the bearing seat 40 and the bearing 41 prevents the nut 50 from contacting and rubbing against the support structure 20, reducing damage to the support structure 20 and effectively extending its service life. Furthermore, it can isolate the nut 50 from the support structure 20, preventing the support structure 20 from rotating during the rotation of the nut 50, and reducing frictional damage to the workpiece caused by the end wall of the support structure 20 near the workpiece.

[0049] According to some embodiments of the present invention, such as Figure 1 As shown, the outer peripheral wall of the mounting rod 10 may be formed with a guide slope 13, which is adjacent to the limiting part 11.

[0050] The outer peripheral wall of the mounting rod 10 may be formed with a guide slope 13, which is adjacent to the limiting part 11 and the second positioning part 34. When the limiting part 11 is inserted into the bowl-shaped plug, the guide slope 13 can guide the mounting rod 10 to smoothly enter the through hole of the bowl-shaped plug. The smooth surface of the guide slope 13 can reduce the risk of the mounting rod 10 colliding with the workpiece. After the limiting part 11 falls into the through hole of the bowl-shaped plug, the picking device 100 is perpendicular to the bowl-shaped plug, and the operating rod 31 is separated from the positioning structure 30. Shaking the picking device 100 causes the second positioning part 34 to fall into the through hole of the bowl-shaped plug. During the process of the second positioning part 34 falling into the through hole of the bowl-shaped plug, the guide slope 13 can guide the second positioning part 34 to fall smoothly into the through hole of the bowl-shaped plug.

[0051] In some embodiments of the present invention, the central axis of the mounting rod 10 and the central axis of the support structure 20 are collinear, which ensures that the mounting rod 10 is always perpendicular to the cup-shaped plug when it is pulled out, thereby preventing the cup-shaped plug from separating from the limiting part 11, thereby reducing the risk of the cup-shaped plug falling off during the removal process, and thus improving the success rate and efficiency of removing the cup-shaped plug.

[0052] Furthermore, the step of taking the cup-shaped plug using the taking device 100 can be as follows: (1) Drill holes in the leaking cup-shaped plug on the workpiece (which can be a motor housing or other parts) using a drill bit tool so that the cup-shaped plug has a through hole. The workpiece can be fixed by a press-fitting mechanism to fix the position of the cup-shaped plug to be removed.

[0053] (2) The support structure 20 is fitted onto the positioning structure 30, and the threaded hole 32 corresponds to the mounting hole 21, and the operating rod 31 is fitted with the threaded hole 32.

[0054] (3) Rotate the nut 50 to the top of the thread on the threaded rod section 12, and move the operating rod 31 in the first direction away from the limiting part 11, so that the operating rod 31 is moved to the end wall of the mounting hole 21 near the nut 50, so that only the limiting part 11 is exposed on the mounting rod 10, and the tilting pick-up device 100 tilts the limiting part 11 into the through hole of the cup-shaped plug.

[0055] (4) Position the picking device 100 perpendicular to the bowl-shaped plug, and separate the operating rod 31 from the positioning structure 30. Shake the picking device 100 so that the second positioning part 34 falls into the through hole of the bowl-shaped plug, so that the mounting rod 10 is perpendicular to the bowl-shaped plug, to ensure that the limiting part 11 and the bowl-shaped plug are in place, and to ensure that the limiting part 11 and the bowl-shaped plug will not separate.

[0056] (5) Assemble the operating rod 31 with the threaded hole 32 and move the operating rod 31 so that the operating rod 31 is located on the end wall of the mounting hole 21 near the limiting part 11.

[0057] (6) Hold the mounting rod 10, rotate the nut 50 until it fits the bearing 41, and then continue to tighten the nut 50 with a wrench so that the mounting rod 10 moves away from the cup-shaped plug in the first direction until the cup-shaped plug is pulled out of the workpiece.

[0058] (7) After pulling out the cup-shaped plug, tilt or flatten the taking device 100, and rotate the nut 50 to the top of the thread on the threaded rod section 12. Move it to the end wall of the mounting hole 21 near the nut 50 by operating the rod 31, so that the limiting part 11 is exposed, and remove the cup-shaped plug from the limiting part 11 to complete the taking of the cup-shaped plug.

[0059] Therefore, by limiting the cup-shaped plug with the limiting part 11, the mounting rod 10 moves relative to the support structure 20 in the first direction, which can easily remove the cup-shaped plug from the workpiece without prying or impacting it, thus reducing damage to the workpiece. Furthermore, the limiting part 11 and the cup-shaped plug can prevent the cup-shaped plug from falling off during the removal process, thereby improving the success rate and efficiency of removing the cup-shaped plug. There is also no need to set up an external drive component to remove the cup-shaped plug, reducing the removal cost of the cup-shaped plug.
