The rotary shuttle is composed of a guide wire, a thread take-off hook, a bobbin case, a shuttle rack, a bobbin, a bobbin case, a shuttle rack positioning hook, a rubber spring and a shuttle door. Therefore, the processing of the rotary shuttle needs to be carried out in steps.

It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0044] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0046] Combination Figure 1-Figure 9 As shown, the present invention provides a sewing machine shuttle processing device, including a drilling mechanism 300, a load-bearing mechanism 200 installed directly below the drilling mechanism 300, a drill position adjustment mechanism 100 arranged directly below the load-bearing mechanism 200, a position control fine adjustment mechanism 400 installed on the drill position adjustment mechanism 100, and a hole placing mechanism 500 installed on the drill position adjustment mechanism 100, and the hole placing mechanism 500 is located directly below the drilling mechanism 300.

[0047] The drilling position adjustment mechanism 100 includes a base 110, a slide plate 120, a control box 130, a left-biased button 140, a right-biased button 150, a motor 160, an eccentric turntable 170 and a pull rod 180.

[0048] The drilling position adjustment mechanism 100 includes a base 110 disposed on a working platform and two slide plates 120 mounted on the base 110;

[0049] The load-bearing mechanism 200 is used to provide longitudinal support force to the drilling mechanism 300 and to provide a transversely movable bearing platform for the three-position drilling of the drilling mechanism 300;

[0050] The load-bearing mechanism 200 includes a slide seat 210 movably mounted between two slide plates 120, a sleeve 220 mounted inside the slide seat 210, a column 230 fixedly mounted at a position deviating from the center of the bottom of the sleeve 220, a pressure-bearing tube 240 fixedly mounted inside the sleeve 220, a first compression spring 250 disposed in the inner cavity of the pressure-bearing tube 240, and a top support rod 260 movably mounted inside the pressure-bearing tube 240 and bearing pressure on the first compression spring 250;

[0051] Rectangular sliders are installed on both sides of the slide seat 210, and the rectangular sliders are adapted to penetrate into the two position control slide grooves;

[0052] Two sets of symmetrically distributed locking bolts are installed on the two side shells outside the sleeve 220, and the two sets of locking bolts are fixed in the holes on the outer wall of the pressure-bearing pipe 240;

[0053] The drilling mechanism 300 is used to perform three-dimensional precise drilling on the rotary hook component;

[0054] The drilling mechanism 300 includes a support plate 310 mounted on the top of the top support rod 260, a handle 320 fixedly mounted on the support plate 310 and placed horizontally, a drill body 330 fixedly mounted on the top of the support plate 310, and a drill bit 340 installed in the drill body 330;

[0055] A slot is formed inside the support plate 310, and the top end of the drill bit 340 fits into the slot;

[0056] The position control fine adjustment mechanism 400 includes a first angle adjustment component 410 and a second angle adjustment component 420 installed on the base 110, a first plug 450 arranged in the first angle adjustment component 410, and a plugging component 460 arranged in the second angle adjustment component 420, the plugging component 460 includes a second plug 461 and a buckle 462 installed on the second plug 461, and a second compression spring 470 is arranged on the rod body of the first plug 450 and the second plug 461;

[0057] The first plug 450 and the second plug 461 are both T-shaped structures, and two ends of the first plug 450 and the second plug 461 away from the hole-releasing mechanism 500 are both equipped with plug rods, and both ends are provided with cross-shaped plug holes;

[0058] The hole-opening mechanism 500 includes a first mold 530 that is pressed against the first plug 450 and a second mold 540 that is pressed against the second plug 461 .

[0059] At present, the guide wire piece in the rotary shuttle is made of a spring steel sheet, which is fastened to the outside of the shuttle case with screws, and is used to limit the needle and thread loop hooked by the shuttle tip at the shuttle root to prevent the needle and thread from slipping off. The thread-off hook is fastened to the lower shaft of the rotary shuttle with screws, and it rotates at high speed along the annular guide rail on the shuttle frame, and uses the shuttle tip at one end to penetrate the needle and thread loop of the needle hole attachment. Therefore, these two components play a vital role in the operation of the rotary shuttle. However, the traditional processing of the thread-off hook and the guide wire piece mainly relies on manual hand-held fixation, and cooperates with the drill bit to perform three-dimensional drilling on the two components. However, there are certain errors in the workers' positioning of the workpiece drilling holes, and each positioning process requires a certain amount of time. At the same time, the method of holding and pressing the workpiece tightly also has great safety hazards.

[0060] The device provides the first mold 530 and the second mold 540 with precise bearing for the off-line hook 550 and the wire piece 560, and cooperates with the first plug 450, the second plug 461, the pad 510 and the two anti-slip rings 520 to tighten the off-line hook 550 and the wire piece 560 under the double protection. At this time, the off-line hook 550 and the wire piece 560 can be ensured to be in a stable state of being stationary and waiting to be drilled without the need for manual hand-held pressure. When the main chuck 413 and the auxiliary chuck 423 are controlled to be quickly flipped and plugged along the holes in the main pad 412 and the auxiliary pad 422 respectively, the first mold 530 and the second mold 540 with precise angle control and rotation assistance can drive the off-line hook 550 and the wire piece 560 to rotate sequentially according to the drilling position of the drill bit 340, thereby improving the accuracy of the three-dimensional drilling of the off-line hook 550 and the wire piece 560, and speeding up the drilling speed without finding the hole position. Example

[0061] Combination Figure 3-Figure 9 As shown, on the basis of Example 1, the drill position adjustment mechanism 100 further includes a control box 130 installed on the top of the base 110, a left-biased button 140 and a right-biased button 150 installed on the outer end of the control box 130, a motor 160 installed inside the control box 130, an eccentric turntable 170 installed on the top of the transmission shaft inside the motor 160, and a pull rod 180 movably installed on the top of the eccentric turntable 170, which is off-center.

[0062] The slide plate 120 is in a U-shaped structure as a whole, and is made of stainless steel;

[0063] A rectangular position-controlling slot is formed inside the slide plate 120 .

[0064] Two slides 120 are used as the load-bearing body of the load-bearing mechanism 200 and the drilling mechanism 300 as a whole. When the worker presses the left-biased button 140 and starts the motor 160 to rotate in the specified direction, the assisted eccentric turntable 170 will drive the pull rod 180 to perform centrifugal motion, and then pull the column 230, the casing 220 and the slide seat 210 to move stably along the two slides 120. At this time, the drilling mechanism 300 as a whole can be offset along the top of the de-wire hook 550 and the guide wire piece 560. When the worker controls the handle 320 and applies pressure to it, the pushed drilling rig body 330 as a whole can cooperate with the drill bit 340 to perform precise three-dimensional drilling operations on the side of the de-wire hook 550 or the guide wire piece 560. Example

[0065] Combination Figure 2-Figure 9As shown, based on the embodiment 1, the first angle adjustment assembly 410 includes a main support plate 411, a main cushion member 412 installed on the top of the main support plate 411, a main chuck 413 inserted in the main cushion member 412, and a main spring 414 bearing pressure on the outer wall of the main chuck 413;

[0066] The main chuck 413 is movably mounted on the plug rod in the first plug 450, and the cross-shaped plug block inside the main chuck 413 is adapted to be clamped in the cross-shaped plug hole in the end of the first plug 450. The end of the first plug 450 close to the first mold 530 is a gradual cam structure;

[0067] The second angle adjustment assembly 420 includes a secondary support plate 421, a secondary cushion member 422 installed on the top of the secondary support plate 421, a secondary clamp 423 inserted into the secondary cushion member 422, and a secondary spring 424 bearing pressure on the outer wall of the secondary clamp 423;

[0068] The auxiliary clamp 423 is movably mounted on the plug rod in the second plug 461, and the cross-shaped plug block inside the auxiliary clamp 423 is adapted to be clamped in the cross-shaped plug hole in the end of the second plug 461;

[0069] Among them, the outer ends of the main clamp 413 and the auxiliary clamp 423 are both installed with latches, and the length of the cross-shaped plug block is twice the length of the latch;

[0070] The position control and fine-tuning mechanism 400 further includes a cross frame 430 installed on the main support plate 411 and the auxiliary support plate 421 , and a cover 440 installed on the top of the cross frame 430 .

[0071] By sequentially stretching the main chuck 413 or the auxiliary chuck 423 outward and controlling the main chuck 413 or the auxiliary chuck 423 to rotate, the main chuck 413 and the auxiliary chuck 423 can respectively drive the first plug 450 and the second plug 461 to rotate. When the pin of the main chuck 413 rotates to the specified hole position inside the main cushion 412, the first plug 450 can control the first mold 530 and the external de-wire hook 550 to flip vertically. At this time, the drill bit 340 can pre-drill the flipped de-wire hook 550. Similarly, the rotation of the auxiliary chuck 423 will also drive the second plug 461 to flip, and the reverse rotating wire piece 560 can cooperate with the offset drill bit 340 to perform drilling operations, thereby allowing the de-wire hook 550 and the wire piece 560 to be quickly processed without manually finding the hole position. Example

[0072] Combination Figure 3-Figure 9As shown, in the above embodiment, the hole placing mechanism 500 further includes a pad 510 installed in the horizontal frame 430 and the cover 440, two anti-slip rings 520 fixedly installed at both ends of the pad 510, a wire slip hook 550 arranged in the outer groove of the first mold 530, and a wire guide piece 560 arranged in the outer groove of the second mold 540;

[0073] The pad 510, the first mold 530 and the second mold 540 are all made of stainless steel;

[0074] The first mold 530 and the second mold 540 are both provided with rectangular slots inside;

[0075] Both ends of the pad 510 are provided with fan-shaped notches adapted to the fan-shaped inserts at the inner ends of the first mold 530 and the second mold 540 .

[0076] The cover 440 and the cross frame 430 are fixed by two combination bolts. At this time, the groove formed by the ring buckle in the middle of the cross frame 430 and the groove formed inside the cover 440 can provide constraints on the pad 510. At this time, the first mold 530 and the second mold 540 assembled on the pad 510 can cooperate with the first plug 450 and the second plug 461 to rotate, and can also serve as a stabilizing platform for the drill bit 340 to punch downward. When the de-wire hook 550 and the wire piece 560 are quickly loaded on the first mold 530 and the second mold 540, the de-wire hook 550 and the wire piece 560 with precise angle adjustment can be quickly drilled, which also improves the safety of workers.

[0077] The working principle and use process of the present invention: the top support rod 260 in the initial state is lifted upward by the first compression spring 250, and the support plate 310 installed on the top of the top support rod 260 will lift the drilling rig body 330 to the highest position. At this time, the drill bit 340 installed on the internal transmission sleeve of the drilling rig body 330 will be suspended above the first mold 530 and the second mold 540;

[0078] When drilling is required for the de-wire hook 550 and the conductor piece 560 of the rough product, the worker needs to stretch the first plug 450 and the second plug 461 outward, then place the de-wire hook 550 of the rough product in a predetermined concave die outside the first mold 530, and place the second plug 461 in a predetermined concave die outside the second mold 540, and then release the first plug 450 and the second plug 461. Under the reset thrust of the two second compression springs 470, the end faces of the second plug 461 and the ring buckle 462 can quickly clamp the conductor piece 560, and the first plug 450 can clamp the de-wire hook 550, and the combined pad 510 and the two anti-slip rings 520 can provide a stable bearing pressure for the de-wire hook 550 and the conductor piece 560. At this time, the de-wire hook 550 and the conductor piece 560 under the triple restraint can maintain absolute stability.

[0079] When the drill body 330 is powered on and the drill bit 340 is driven to rotate at high speed, the worker manually presses the handle 320, and the support plate 310 and the drill body 330 can be lowered as a whole, and the high-speed rotating drill bit 340 can drill holes on the side of the off-line hook 550 or the wire sheet 560. When the hole position of the off-line hook 550 or the wire sheet 560 needs to be selected, the worker needs to adjust the auxiliary clamp 423 or the main clamp 413 to stretch outwards again. When the auxiliary clamp 423 and the main clamp 413 are respectively pulled out of the auxiliary cushion 422 and the main cushion 413, 2, the worker needs to rotate the auxiliary chuck 423 or the main chuck 413 until the blocking component 460 as a whole and the first blocking component 450 can be accurately turned 90 degrees, and the first mold 530 and the second mold 540 that are assisted in rotation can respectively drive the de-wire hook 550 and the wire sheet 560 to perform corresponding turns until the drill bit 340 performs accurate equidistant drilling operations on the de-wire hook 550 and the wire sheet 560, which can reduce the burden of workers in finding and controlling positions, and at the same time, can avoid causing safety hazards to workers;

[0080] When one of the de-threading hook 550 or the guide wire piece 560 has completed the three-position drilling, the left-biased button 140 or the right-biased button 150 can be pressed, and the started motor 160 will run, and its internal transmission shaft will drive the eccentric turntable 170, which will then drive the pull rod 180 to extend, and the column 230, the sleeve 220 and the slide seat 210 can move laterally at a uniform speed on the inner side of the two slides 120. At this time, the load-bearing mechanism 200 as a whole can drive the drilling mechanism 300 as a whole to move toward the top of the undrilled workpiece, and according to the above-mentioned operating steps, the drill bit 340 that is repeatedly pressurized and falls downward can perform a fast three-position drilling operation on the undrilled rotary shuttle assembly, thereby greatly improving the three-position drilling accuracy of the de-threading hook 550 and the guide wire piece 560, and at the same time improving the drilling efficiency of the de-threading hook 550 and the guide wire piece 560.

[0081] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
