[0008] For a more complete understanding of the present invention, and the advantages thereof, reference is now made to the following descriptions taken in conjunction with the accompanying drawings, in which: [Brief description of the drawings]
[0009] [Figure 1] FIG. 1 illustrates an automatic tack actuation system according to some embodiments. [Figure 2A] 1 is a perspective view of an automatic temporary fastener actuation tool according to some embodiments. [Figure 2B]1 is a cross-sectional view of an automatic temporary fastener actuation tool according to some embodiments. [Diagram 3] 1A-1D illustrate some embodiments of temporary fasteners.

[0010] Temporary fasteners, such as Cleco fasteners, are used in manufacturing processes to fasten dissimilar materials together during the manufacturing process. Once these dissimilar materials are joined, workers may perform other processes to physically join the materials. The temporary fasteners are then removed from the joined materials for the next assembly operation. The current process for applying and removing the temporary fasteners is manual and time consuming.
[0011] To solve these and other problems that arise when manually actuating temporary fasteners, e.g., Cleco fasteners, the disclosed embodiments provide an automatic temporary fastener actuation tool and system. Instead of the typical manual process currently used to apply and remove temporary fasteners, e.g., Cleco fasteners, the disclosed embodiments actuate the temporary fasteners quickly and automatically, thereby saving substantial time and expense. To do so, some embodiments utilize a rotating tool, e.g., a multi-function end effector (MFEE), and a temporary fastener actuation tool to actuate the temporary fasteners, e.g., Cleco fasteners. The rotating tool rotates a shaft within the temporary fastener actuation tool, which automatically actuates the temporary fasteners to either remove them or apply them to a panel. As a result, the temporary fasteners, e.g., Cleco fasteners, can be automatically actuated without the need for manual intervention by an operator.
[0012] To facilitate a better understanding of the present invention, the following examples of certain embodiments are given. The following examples should in no way be read to limit or define the scope of the present invention. The embodiments of the present invention and its advantages can be best understood by referring to the accompanying drawings, in which the same reference numerals are used to indicate the same and corresponding parts.
[0013] 1 illustrates some embodiments of a temporary fastener actuation system 100. The temporary fastener actuation system 100 includes a rotating tool 110, a temporary fastener actuation tool 120, and a temporary fastener 130. Typically, the temporary fastener actuation tool 120 is coupled to or otherwise operated by the rotating tool 110. The temporary fastener 130 is inserted into the temporary fastener actuation tool 120, which then inserts the teeth (i.e., teeth 306) of the temporary fastener 130 into aligned holes in the panel 140. The rotating tool 110 then rotates a shaft (i.e., motor shaft 121) within the temporary fastener actuation tool 120, which rotates the stem (i.e., stem 302) of the temporary fastener 130. This actuates the teeth of the temporary fasteners 130 and temporarily secures the temporary fasteners 130 to the panel 140, thereby securing the panels 140 together for manufacturing purposes. The rotating tool 110 can also rotate the motor shaft 121 in the reverse direction within the temporary fastener actuation tool 120 in order to retract the teeth of the temporary fasteners 130 and loosen them from the panel 140.
[0014] The rotating tool 110 is any suitable tool or device capable of actuating the temporary fasteners 130 as described herein. In some embodiments, the rotating tool 110 is a multi-function end effector (MFEE) or a three-axis robotic system (e.g., manufactured by Kuka Aerospace). Generally, the rotating tool 110 is captively or otherwise attached to the temporary fastener actuation tool 120, positions and aligns the temporary fastener actuation tool 120 with holes in the panel 140, and spins the motor shaft 121 within the temporary fastener actuation tool 120 to actuate the temporary fasteners 130 as described herein. For example, the rotating tool 110 may be configured to rotate the motor shaft 121 and inner bearing 126 in a first direction while the outer bearing 125 is stationary, thereby expanding the teeth of the temporary fasteners 130. As another example, the rotation tool 110 can rotate the motor shaft 121 in a second direction (opposite to the first direction) while the outer bearing 125 is stationary, thereby compressing the teeth of the temporary fastener 130. In yet another example, the rotation tool 110 can be configured to rotate the motor shaft 121 and the outer bearing 125 in a first direction while the inner bearing 126 is disengaged from the stem 302, thereby rotating the entire body of the temporary fastener 130.
[0015] 2A and 2B illustrate some embodiments of the temporary fastener actuation tool 120. In some embodiments, the temporary fastener actuation tool 120 is generally cylindrical in shape as shown. This allows the temporary fastener actuation tool 120 to be at least partially inserted into a tool receptacle of the rotating tool 110 and coupled to the rotating tool 110. In some embodiments, the temporary fastener actuation tool 120 includes a motor shaft 121, a protrusion 122, one or more spring clips 124 (e.g., 124a and 124b), an outer bearing 125, an inner bearing 126, a bearing shell 127, a spindle 128, and threads 129. The motor shaft 121 is coupled to the bearing shell. Both the motor shaft 121 and the bearing shell 127 are configured to rotate within the temporary fastener actuation tool 120 about an axis 210. In some embodiments, the motor shaft 121 includes a spindle 128 coupled to one end of the motor shaft 121 as shown. In such an embodiment, the bearing shell 127 has threads 129 that couple the bearing shell 127 to the spindle 128. The motor shaft 121 generally transfers rotational power from the rotating tool 110 to the bearing shell 127 to rotate the inner bearing 126. This rotates the stem 302 of the temporary fastener 130, which in turn actuates the temporary fastener 130.
[0016] The protrusion 122 is coupled to an end 220 of the temporary fastener 130 as shown. In general, the protrusion 122 helps to hold the temporary fastener 130 in the temporary fastener actuation tool 120. In some embodiments, the protrusion 122 has a groove 230 that matches the cross-sectional shape of the recess 301 of the temporary fastener 130. For example, if the body 300 and recess 301 are cylindrical in shape as shown, the groove 230 is circular in shape as shown. This allows the recess 301 of the temporary fastener 130 to be held securely in place against the protrusion 122 (i.e., the recess 301 fits into the groove 230 while a portion of the body 300 fits into the inner portion 260 of the protrusion 122). To help hold the temporary fastener 130 against the protrusion 122, some embodiments of the temporary fastener 130 have one or more spring clips 124. The spring clips 124 are coupled to ends 220 of the temporary fasteners 130 as shown. Each spring clip 124 has an end 240 that is aligned with an end 250 of the projection 122. The spring clips 124 may be made of metal, plastic, or any other suitable material that allows the spring clips 124 to be flexible and spring loaded.
[0017] In some embodiments, the outer bearing 125 is configured to contact the body 300 of the temporary fastener 130 and hold the body 300 of the temporary fastener 130 stationary during actuation of the temporary fastener 130. For example, the outer bearing 125 can have an inner diameter that allows the outer bearing 125 to contact the body 300 and hold it stationary.
[0018] In some embodiments, the outer bearing 125 is configured to contact the body 300 of the temporary fastener 130 and rotate the body 300 during actuation of the temporary fastener 130. For example, the outer bearing 125 can have an inner diameter that allows the outer bearing 125 to contact and rotate the body 300.
[0019] In some embodiments, the outer bearing 125 is located near the end 220 of the temporary fastener actuation tool 120, as shown. In some embodiments, the outer bearing 125 is tubular in shape so that at least a portion of the temporary fastener 130 can be inserted into the outer bearing 125.
[0020] The inner bearing 126 is configured to contact the stem 302 of the temporary fastener 130 and rotate the stem 302 during actuation of the temporary fastener 130. In some embodiments, the inner bearing 126 is located near the outer bearing 125, as shown. In some embodiments, the inner bearing 126 is tubular in shape such that at least a portion of the temporary fastener 130 (e.g., the stem 302) can be inserted into the inner bearing 126. Generally, the inner bearing 126 has an inner diameter that allows the inner bearing 126 to contact and rotate the stem 302.
[0021] In some embodiments, the collar 170 fits onto the body 300 of the temporary fastener 130 in a press fit manner to hold the body 300 stationary while the stem 302 of the temporary fastener 130 is actuated by the inner bearing 126. In some embodiments, the collar 170 allows the body 300 of the temporary fastener 130 to rotate while the stem 302 of the temporary fastener 130 is actuated by the outer bearing 125. The collar 170 may be located near the end 220 of the temporary fastener actuation tool 120 as shown. In some embodiments, the collar 170 is tubular in shape. The collar 170 may be constructed of any suitable material, such as plastic.
[0022] The temporary fasteners 130 are any suitable fasteners for holding together the panels 140. In some embodiments, the temporary fasteners 130 are Cleco fasteners. Particular embodiments of the temporary fasteners 130 are described in more detail below with reference to FIG.
[0023] Panel 140 is a material or object that is to be joined together during manufacturing. In some embodiments, for example, panel 140 is an aircraft panel. As another example, panel 140 is an automobile panel. Generally, panel 140 has holes that align with temporary fasteners 130 and through which the temporary fasteners can be inserted to hold panel 140 together.
[0024] 3 illustrates certain embodiments of temporary fasteners 130. Temporary fasteners 130 may be of any suitable size, height, shape, and any combination thereof. In some embodiments, temporary fasteners 130 may include any suitable material, including, but not limited to, metals, non-metals, polymers, ceramics, composites, and any combination thereof. Temporary fasteners 130 may be any suitable fastener and are not intended to be limiting of the invention. In some embodiments, temporary fasteners 130 are Cleco fasteners.
[0025] In some embodiments, the temporary fastener 130 can include a body 300, a recess 301, a stem 302, a spreader bar 304, a pair of teeth 306a, 306b, a pair of barbs 308a, 308b, and a compressible gasket 412. The body 300 and the recess 301 can be generally cylindrical in shape, with the recess 301 having a smaller diameter than the portions of the body 300 on each end of the recess 301, as shown. The body 300 can be configured to receive at least a portion of the stem 302, which can be configured to translate in opposite directions relative to the body 300. For example, the stem 302 can be secured within and secured to the body 300. In one or more embodiments, the stem 302 can be threaded into and within the body 300. In operation, rotation of the top portion 312 of the stem 302 extending from the body 300 can cause the stem 302 to translate along the central axis of the body 300 .
[0026] In some embodiments, the spreader bar 304 can be coupled to an end of the body 300 opposite the top portion 312. As shown, the spreader bar 304 can extend outwardly from the body 300 and the teeth 306 can be disposed adjacent the spreader bar 304. A first tooth 306a can be disposed along one side of the spreader bar 304 and a second tooth 306b can be disposed along the opposite side of the spreader bar 304. The teeth 306 can each be coupled to a stem 302. When the stem 302 is actuated to rotate, the spreader bar 304 can remain stationary and the teeth 306 can translate with the stem 302. In one or more embodiments, the teeth 306 can retract rearwardly into the body 300 and the spreader bar 304 can be configured to spread the teeth 306 radially outward. In one or more embodiments, the teeth 306 extend outwardly from the body 300 and the distance between the teeth 306 can decrease radially. In some embodiments, the barbs 308 can be located at the distal ends of the teeth 306. A first barb 308a can be located at the distal end 314 of the first tooth 306a and a second barb 308b can be located at the distal end 316 of the second tooth 306b. In some embodiments, the barbs 308 can be sequentially translated, extended, and retracted upon actuation of the teeth 306.
[0027] 4A and 4B illustrate temporary fasteners 130 that join separate panels of material together. As shown, the temporary fasteners 130 may be at least partially inserted into holes in the first panel of material 400 and the second panel of material 402. The first panel of material 400 and the second panel of material 402 may each be of any suitable size, height, shape, and any combination thereof. In some embodiments, the first panel of material 400 and the second panel of material 402 may each comprise any suitable material, including, but not limited to, metals, non-metals, polymers, ceramics, composites, and any combination thereof. In some embodiments, the teeth 306 and barbs 308 may be inserted through the first side 404 of the first panel 400 and may exit the second side 410 of the second panel 402, where the second side 406 of the first panel 400 rests against the first side 408 of the second panel 402. To apply force to clamp the panels 400, 402 together, the stem 302 (see FIG. 3) of the temporary fastener 130 may be rotated to retract the teeth 306. As the teeth 306 retract, the spreader bar 304 (see FIG. 3) may radially define the teeth 306 and then the barbs 308. The barbs 308 may expand beyond the size of the holes in the panels 400, 402, and the barbs may abut the second panel 402 against the second side 410. The temporary fastener 130 can then be further actuated, causing the barb 308 to apply a force to the rear of the second panel 402. As shown, a compressible gasket 412 can be provided at one end of the body 300 (see FIG. 3), which can provide protection for the body 300 and / or the first panel 400. A compressive force can be applied to both the first panel 400 and the second panel 402 between the gasket 412 and the barb 308, which can temporarily secure the first panel 400 to the second panel 402.
[0028] 1-4B, in explaining operation, the disclosed embodiments provide a temporary fastener actuation system 100 that utilizes a temporary fastener actuation tool 120 to automatically actuate a temporary fastener 130. Instead of the typical manual process currently used to install and remove temporary fasteners, such as Cleco fasteners, the disclosed embodiments actuate the temporary fasteners quickly and automatically, thereby saving considerable time and expense. To do so, the temporary fasteners 120 are first coupled to or otherwise attached to the rotating tool 110. Next, if the temporary fasteners 130 are already installed in the panel 140, the temporary fastener actuation tool 120 is manipulated (either manually or automatically by the rotating tool 110) so that the axis 210 is aligned with the installed temporary fasteners 130. The temporary fastener actuation tool 120 is then moved so that the temporary fasteners 130 are driven into the temporary fasteners 130. Once inserted into the temporary fastener 130, the spring clip 124 and protrusion 122 align with and contact the recess 301, thereby securing the temporary fastener 130 within the temporary fastener actuation tool 120. The body 300 contacts the outer bearing 125 and the stem 302 contacts the inner bearing 126 within the temporary fastener 130. The motor shaft 121 is then rotated by the rotating tool 120, thereby rotating the bearing shell 127, the inner bearing 126, and finally the stem 302. The outer bearing 125 prevents the body 300 of the temporary fastener 130 from rotating while the stem 302 is rotated by the inner bearing 126, thus actuating the temporary fastener 130 and compressing the teeth 306. This loosens the temporary fastener 130 and frees it from the panel 140. The temporary fastener actuation tool 120 is then retracted away from the panel 140 , thereby pulling the temporary fasteners 130 free from the panel 140 .
[0029] When the temporary fastener actuation system 100 is used to install the temporary fastener 130 into the panel 140, the temporary fastener 130 may first be inserted into the temporary fastener actuation tool 120. Once inserted into the temporary fastener 130, the spring clip 124 and protrusion 122 align with and contact the recess 301, thereby securing the temporary fastener 130 within the temporary fastener actuation tool 120. The body 300 contacts the outer bearing 125 and the stem 302 contacts the inner bearing 126. The motor shaft 121 is then rotated in the opposite direction by the rotating tool 120, thereby rotating the bearing shell 127, the inner bearing 126, and finally the stem 302. The outer bearing 125 prevents the body 300 of the temporary fastener 130 from rotating while the stem 302 is rotated by the inner bearing 126, thereby actuating the temporary fastener 130 to spread the teeth 306. This secures the temporary fastener 130 onto the panel 140.
[0030] When the temporary fastener actuation system 100 is used to free the temporary fastener 130 from a sealant that may have cured and bonded to the temporary fastener 130, the outer bearing 125 of the temporary fastener actuation tool 120 contacts and rotates the body 300 of the temporary fastener 130. The collar 170 is configured to contact and hold the body 300 of the temporary fastener 130 stationary as the stem 302 is rotated in the reverse direction.
