Description

Button press

The invention relates to a pressing device for a button (Eyelet, also known as a corn nail, or an eye button).

The button is usually composed of a Washer and a tubular structure which is integrally formed with one of the two huasi. When the Huashi is combined as a button, a press-fit device turns the tubular structure into a riveted structure, which achieves the purpose of combining the two Huashi.

The pressing device of the Taiwan Patent No. M297178 is composed of a mold base and a pressing rod. The mold base protrudes from a positioning rod, and the root of the positioning rod is surrounded by a concave arc edge formed on the surface of the mold base. When the positioning rod passes through the hole of the working object and the single piece of the washer, the pressing rod impacts the washer along a direction substantially perpendicular to the workpiece, forcing the tubular structure to be bent into a riveted structure by the concave arc edge, thereby joining the work around the hole The part is completed, and the assembly work of the eye button is completed.

The press-fit device of Taiwan Patent No. M481257 consists of a two-die seat, two long plates and a pin. One end of the long plates is connected in series by a pin as a hinge structure, and the pin supports the two long plates to perform reciprocating movements in the circumferential direction, which are opposite to each other and reversely separated. These mold bases are riveted to the corresponding long plates, and the two-dimensional joints are assembled at the holes of the work object to complete the assembly work of the buttons.

The invention provides a new button pressing device, one of the main purposes of which is to complete the operation of pressing the button between the upper and lower two molds by using a structure in which the torque is converted into a linear movement.

The invention provides a new button pressing device, one of the main purposes of which is: the pressure The device can be used both hand-held and stably arranged at the work site, and the button press action is performed by one of the manual and automatic modes.

For the purpose of the above object, the button press device of the present invention includes: a main body having a connecting portion, the connecting portion supporting a first arm and a second arm opposite to each other; and being disposed on the first arm a detached lower mold; a stud disposed on the second arm, the stud being driven by an external force and linearly displaceable toward the first arm; a detachable upper mold coupled to the stud, the lower mold and the lower mold facing each other A bearing assembly disposed between the upper mold and the stud can withstand a load along the axial direction of the stud.

In the press cooperation, the bearing assembly converts the rotational kinetic energy of the stud into a linear down force, which is not necessary for the stud to rotate, and which is pressed together with the lower die by a button.

The second arm has a ring portion for screwing the stud, and the stud has a limiting portion, and the limiting portion cooperates with the ring portion to determine a stroke of the stud relative to the displacement of the main body.

The combination of the stud and the upper mold has the following several configurations: the first combined mode: the stud has a socket extending from the restricting portion toward the lower mold, and the sleeve passes through the bearing. The assembly forms a recess on the end surface of the socket. The upper mold has a convex portion having a ball body having an elastic force and one of elastic rings surrounding the tightening convex portion. When the convex portion is inserted into the concave portion of the socket portion, the one of the beads and the elastic ring urges the wall surface of the concave portion to support the upper mold and the stud.

a second bonding mode: the stud has an insertion portion extending from the restricting portion toward the lower mold, the insert portion being inserted into the deep recess formed in the upper mold by the bearing assembly, and exceeding the bearing assembly at the insertion portion The portion is configured to prevent the bearing assembly from leaving the buckle of the insertion portion. In the insertion section When the deep recess of the upper mold is combined, the insert portion has one of an elastic bead and an elastic ring around the tightening insertion portion, and the one of the bead and the elastic ring is pressed against the wall surface of the deep recess to support the upper mold and the stud. integrate.

As for the torque transmission mode, distinguish between manual and automatic modes. In the manual mode: the stud has a force receiving portion and a hole penetrating through the force receiving portion, allowing a rod to pass through the hole of the force receiving portion. The rod is manipulated by a user to apply torque to the stud.

In terms of the automatic mode: the stud has a polygonal force receiving portion, and the sleeve is combined with the force receiving portion and the operating portion of an electric/pneumatic tool. After being energized, the electric/pneumatic tool can output torque to the force receiving part, and the stud can automatically perform the same direction rotation operation.

In addition, the button press device of the present invention further has a die holder that incorporates the first arm and the lower die. Regarding the configuration of the die holder coupling first arm and lower die, the details are as follows: The first arm has a coupling hole which is composed of a large diameter chamber and a small diameter chamber which communicate with each other. The top surface of the mold base defines a recess, the bottom surface of which protrudes into the externally threaded section of the large diameter chamber through the small diameter chamber, and a nut that is inserted into the large diameter chamber locks the externally threaded section. The lower mold has a convex portion which is provided with one of a steel ball having an elastic force and an elastic ring around the tightening convex portion. When the convex portion is inserted into the concave portion of the mold base, one of the steel ball and the elastic ring is pressed against the wall surface of the concave portion to support the lower mold to be coupled to the mold base.

In particular, a disc spring is placed over the outer threaded section just between the first arm and the nut. Therefore, the disc spring pushes the nut and drives the externally threaded section to maintain the mold base together with the lower mold. Even if the diameter of the small diameter chamber is larger than the diameter of the outer thread segment, the outer thread segment is slightly deflected relative to the first arm during the impact of the upper die against the lower die, so that the upper and lower two molds remain aligned.

In addition to the main body being gripped by the user, the following configuration can be adopted to stably arrange the button pressing device at the work place to complete the automatic operation of the button press.

Briefly, the first arm has two annular fixing portions and a screw hole. The fixing portion is on both sides of the first arm, allowing the two fasteners fastened to the support member to pass through the corresponding fixing portions. Alternatively, the screw hole and the coupling hole are on both sides of the connecting portion, and above it is a flat portion formed on the connecting portion, and the flat portion cooperates with a clamping member that locks the screw hole to sandwich the other supporting members.

In this way, the pressing device of the present invention adopts the structure in which the stud is locked into the second arm, and the function of torque conversion into a linear movement can be easily achieved, and the pressing cooperation of the upper and lower two modes on the button is completed.

At the same time, the fixing portion, the clamping member and the flat portion can arrange a series of pressing devices at the working place to quickly complete the automatic pressing of the button pressing in the work. Even with a single press-fit device, the manual press or electric/pneumatic tools can be used to complete the press-fitting of the buttons, which is easier than the prior art described above.

Figure 11 is an action diagram in which the buttons are joined together by a press-fit device.

The first and second drawings illustrate the first embodiment of the pressing device. The specific structure is composed of a main body 10, a stud 20, an upper mold 30, a bearing assembly 31, a lower mold 36 and a mold base 40.

In terms of structure, the main body 10 is designed as a C-shaped body, and is defined as a first arm 11, a connecting portion 15 and a second arm 17. The connecting portion 15 supports the first arm 11 and the second arm 17 in a space-free manner. When the connecting portion 15 is held by a user, the entire pressing device is in the manual mode, and a button 50 is pressed. The first arm 11 is parallel to the second arm 17 and the lower die 36 is disposed on the first arm 11. The stud 20 is a cylinder having an external thread that maintains a threaded relationship with the second arm 17. When the stud is driven by an external force (usually referred to as torque), it can be linearly reciprocatingly displaced toward the first arm 11. The upper mold 30 is detachably coupled to the stud 20, and the lower mold 36 faces each other.

The bearing assembly 31 referred to herein generally refers to a Thrust Ball Bearing. The thrust ball bearing is disposed between the upper die 30 and the stud 20 and can withstand a load along the axial direction of the stud 20 .

3 to 5, the second arm 17 has a ring portion 18, the inner surface of which forms an internally threaded section 181 such that the stud 20 and the ring portion 18 remain in a threaded relationship. The stud 20 extends in the radial direction by a circular restricting portion 23 that abuts against the bottom surface of the ring portion 18 as a starting point for displacement of the stud 20 . Therefore, in the stroke in which the stud 20 moves relative to the main body 10, the ring portion 18 and the restricting portion 23 become one of the determining factors.

There are various options for the manner in which the stud 20 is coupled to the upper mold 30. In this embodiment, the stud 20 has a set of joints 24 extending from the restricting portion 23 toward the lower die 36 so as to pass through the bearing assembly 31 and form an end face of the sleeve portion 24. Concave portion 25. A loop fastener 27A is fitted in a circumferential groove 24A formed in the circumferential direction on the surface of the socket portion 24 to prevent the bearing assembly 31 from leaving the socket portion 24. The upper mold 30 has a convex portion 32. The convex portion 32 is provided with a bead body 33 and a compression spring (not labeled), so that the bead body 33 is pushed by the compression spring to partially expose the convex portion 32.

In some embodiments, an annular elastic band bundle is wrapped around the convex portion 32, and the convex portion 32 is preferably immersed in a groove that accommodates the elastic ring.

When the convex portion 32 is inserted into the concave portion 25 of the socket portion 24, the bead body 33 is in contact with one of the elastic rings and is pressed against the wall surface of the concave portion 25, and the upper mold 30 is not easily dropped under the stud 20, and the upper mold is not easily dropped. The end surface of the 30 is formed with a chamber 30A surrounding the convex portion 32, and the chamber 30A receives the portion of the socket portion 24 beyond the bearing assembly 31 and the buckle 27A.

In the present embodiment, the press device transmits the required torque in a manual mode. Briefly, the stud 20 has a force receiving portion 21 through which a hole 22 extends to allow the passage of a rod 53 through the hole 22 of the force receiving portion 21. The rod 53 is manipulated by a user to apply torque to the stud 20.

In Figures 3, 4, and 6, a die holder 40 bonds the first arm 11 and the lower die 36 together. Specifically, the first arm 11 has a coupling hole 14 which is composed of a large diameter chamber 141 and a small diameter chamber 142 which communicate with each other. The top surface of the mold base 40 defines a recess 41. An outer thread portion 42 protrudes from the bottom surface of the mold base 40. The outer thread portion 42 enters the large diameter chamber 141 through the small diameter chamber 142 for locking a large diameter chamber 141. The nut 45 supports the mold base 40 to smoothly contact the surface of the first arm 11. A gasket 43 is placed over the externally threaded section 42 and is pressed against the wall of the large diameter chamber 141 by the nut 45.

The lower die 36 also has a convex portion 37 which is provided with a steel ball 38 having an elastic force. When the convex portion 37 is inserted into the concave portion 41 of the mold base 40, the steel ball 38 is pressed against the wall surface of the concave portion 41, and the lower mold 36 is supported to be bonded to the mold base 40 without being easily separated.

In some embodiments, there are no steel balls, but an annular elastic ring is used to tighten around the projections 37. Of course, it is also within the tolerance of the present invention that the convex portion 37 is immersed in a groove for accommodating the elastic ring. When the convex portion 37 is inserted into the concave portion 41 of the mold base 40, the elastic ring can also be urged against the wall surface of the concave portion 41, and the lower mold 36 is supported to be bonded to the mold base 40 without being easily separated.

As seen from the first, third, and eleventh figures, the button 50 includes two washers 51 and 52 which are annular. Wherein, the Huasi 51 has a tubular structure (not labeled), and the Huasi 51 falls into a formation A second recess 391 of the end face of the die 36 surrounds a receiving portion 39 that is trapped in the center of the lower die 36 and supports the tubular structure toward the upper die 30. Further, the washer 52 is placed on a punch 34 formed on the upper die 30 to contact a first recess 35 formed on the end face of the upper die 30.

When the tubular structure passes through a hole (not shown) of a work object (such as canvas, paper or other flat object), the tubular structure is expanded outward by the increasing diameter of the punch 34, and follows the first recess 35. The winding is reversed until the punch 34 penetrates the receiving portion 39 of the lower mold 36. At this moment, the tubular structure is converted into a riveted structure, and the two washers 51 and 52 are pressed and joined together in the direction of the second pocket 391 so as to be sandwiched on both sides of the workpiece without being easily separated.

The pressing device adopts the structure that the stud 20 is locked into the second arm 17, and the function of converting the spiral motion into a linear reciprocating displacement can be easily achieved, and the pressing cooperation of the upper and lower two molds 30 and 36 on the button 50 is completed. Even if the user grips the connecting portion 15 of the main body 10 with one hand, and the other hand operates the rod body 53 to rotate the stud 20, the press cooperation of the button 50 is more easily accomplished than the prior art.

In addition, the press device can be stably arranged at a fixed working place. As shown in the first and fourth figures, the first arm 11 has two annular fixing portions 12, and the fixing portions 12 are provided on the two sides of the first arm 11 by two fasteners 55 (such as bolts, screws, etc.). The fixing portion 12 is further fixed to a support member 56 (for example, a surface).

Or, as in the first and third figures, the first arm 11 further has a screw hole 13 and the coupling hole 14 and the coupling hole 14 are on both sides of the connecting portion 15. A flat portion 16 is integrally formed with the connecting portion 15 just above the screw hole 13. The flat portion 16 cooperates with a clamping member 19 that locks into the screw hole 13 to collectively sandwich other support members 54 (e.g., the periphery of the table).

Figure 7 is a second embodiment of the press-fit device, which is constructed substantially the same as the first embodiment, with the difference being in the manner in which the torque is automatically transmitted.

The force receiving portion 211 of the stud 20 is polygonal and can be inserted into the tubular opening 59 below the sleeve 57. The mouth 59 above the sleeve 57 is combined with an operating portion 58, which belongs to a The part of the electric/pneumatic tool (not shown). After being energized, the electric/pneumatic tool outputs torque to the force receiving portion 211, and the associated stud 20 automatically performs the co-rotation operation.

In particular, it is very simple and labor-saving to arrange a series of press-fit devices at the same work location, with the entire row of electric/pneumatic tools to complete the automated control of the press-buttons.

Fig. 8 is a third embodiment of the press-fit apparatus, which is substantially identical in construction to the first embodiment, except that the stud 20 has a different bonding mode from the upper mold 30.

In the figure, the stud 20 has a solid insertion portion 26 instead of the original socket. The insertion portion 26 extends from the restricting portion 23 in the direction of the lower mold 36 (see Fig. 3), and is passed through the bearing assembly 31 (see Fig. 3) to enter a deep recessed portion 322 formed in the upper mold 30. The bead body 33 (or the elastic ring) is disposed at a portion of the insertion portion 26 beyond the bearing assembly 31. When the insertion portion 26 is coupled to the deep recessed portion 322 of the upper mold 30, the bead body 33 (or the elastic ring) contacts. And pressing against the wall surface of the deep recess 322, the upper mold 30 and the stud 20 are supported to be joined together.

Next, a retaining ring 27 is fitted to the insertion portion 26 to provide a blocking effect on the bearing assembly 31 (see FIG. 3) that is fitted over the insertion portion 26, thereby preventing the bearing assembly 31 from leaving the insertion portion 26. At the same time, a shallow recess 321 is formed on the end surface of the upper mold 30, which is in communication with the deep recess 322, and can accommodate the buckle 27 without affecting the combination of the stud 20 and the upper mold 30.

Figures 9 and 10 are a fourth embodiment of the press-fit apparatus, which is substantially identical in construction to the first embodiment, with the difference that an additional disc spring 44 is provided. The disc spring 44 is fitted over the externally threaded section 42, just between the wall of the large diameter chamber 141 of the first arm 11 and the nut 45. The disc spring 44 has an arcuate cross-section that resists the shim 43 and generates a thrust to the nut 45, causing the outer thread segment 42 to pull the die holder 40 together with the lower die 36 to remain stationary in the first arm 11.

In the figure, the diameter of the small diameter chamber 142 is larger than the diameter of the outer thread segment 42, and there is a gap 401 therebetween. Even if the upper die 30 (see FIG. 3) hits the lower die 36, the externally threaded section 42 Because of the gap 401, a slight yaw is generated with respect to the first arm 11, so that the upper and lower molds 30, 36 are kept in alignment. At the same time, the disc spring 44 is deformed according to the yaw of the external thread segment 42. After the yaw relationship of the external thread segment 42 is released, the disc spring 44 is restored to the original shape, so that the die holder 40 and the lower die 36 are restored to a smooth state. status.
