[0043] Referring to Figures 1 to 6 , the torsion actuating device of the utility model will be described below by several embodiments.

[0044] As Figures 1 to 6 indicated, the torsion actuating device 100 of the utility model embodiment comprises a clamp mechanism 110, a frame structure 700, a power mechanism 400 and a transmission mechanism 500. Specifically, the clamp mechanism 110 comprises a rotary table 200 and a positioning mechanism 300, the rotary table 200 is used to connect the roller 910 or the lens barrel 920 at one end of the zoom lens 900, and the positioning mechanism 300 is used to connect the lens barrel 920 or the roller 910 at the other end of the zoom lens 900. The power mechanism 400 comprises a rotating motor 410, and the rotating motor 410 and the positioning mechanism 300 are connected to the frame structure 700 respectively, when the zoom lens 900 is put into the torsion actuating device 100, one end of the zoom lens 900 connected with the positioning mechanism 300 is in a stationary state.

[0045] It can be understood that the transmission mechanism 500 comprises a driving shaft 510, a driven shaft 520 and a connecting piece 530, as Figure 4 indicated. The output end of the rotating motor 410 and the driving shaft 510 are in transmission connection, so that the driving shaft 510 makes rotational motion. The opposite ends of the connecting piece 530 are in transmission connection with the driving shaft 510 and the driven shaft 520 respectively, so as to convert the uniform rotational motion of the driving shaft 510 into the reciprocating rotational motion of the driven shaft 520. The driven shaft 520 and the rotary table 200 are connected, so that the rotary table 200 makes reciprocating rotational motion relative to the positioning mechanism 300.

[0046] In this way, the torsion actuating device 100 realizes repeated zooming of the zoom lens 900 through the power output by the rotating motor 410, so that the roller 910 and the lens barrel 920 are ground, thereby reducing the torsion of the zoom lens 900 and improving the production efficiency of the zoom lens 900. Moreover, manual repeated zooming is not needed, the worker only needs to put in or take out the zoom lens 900, and turn on or off the rotating motor 410, thereby reducing the labor cost and labor intensity of the workers.

[0047] In the embodiment, the turntable 200 is connected with the roller 910 of the zoom lens 900, the positioning mechanism 300 is connected with the lens barrel 920 of the zoom lens 900, and the positioning mechanism 300 is located above the turntable 200, as shown in Figure 1

[0048] In some embodiments, the rotating motor 410 is a reversible motor, and the connecting member 530 is a transmission gear. The transmission gear is rotationally connected to the frame structure 700. The driving shaft 510 and the driven shaft 520 are respectively threadedly engaged with the transmission gear. The driving direction is switched by the reversible motor, so as to realize the reciprocating rotation of the turntable 200. However, the reversible motor repeatedly changes the driving direction, which needs high-cost setting and maintenance, and the driving direction needs to be switched, which takes time, resulting in a large production time.

[0049] In other embodiments, the driving shaft 510, the driven shaft 520 and the connecting member 530 form a cam mechanism. Specifically, the connecting member 530 includes a cam, a rotating wheel and a swing rod. The cam is connected with the driving shaft 510. One end of the swing rod is rotationally connected with the rotating wheel, and the other end of the swing rod is connected with the driven shaft 520. The rotating wheel moves along the cam surface. The rotating motor 410 is a common motor. When the output end of the rotating motor 410 drives the driving shaft 510 to rotate, the cam rotates around the axis of the driving shaft 510 and drives the rotating wheel to move. At this time, the swing rod makes reciprocating swing motion, so that the driven shaft 520 and the turntable 200 connected therewith make reciprocating rotation. However, the cam mechanism is prone to the motion discontinuity of the swing rod and the driven shaft 520 connected therewith, which affects the production efficiency.

[0050] In the embodiment, the driving shaft 510, the driven shaft 520 and the connecting member 530 form a crank rocker mechanism, as shown in Figure 4 Specifically, the rotating motor 410 is a common motor. The connecting member 530 includes a driving piece 531, a driven piece 532 and a connecting rod 533. The driving shaft 510 extends in the up-down direction and is coaxially connected with the driving piece 531. The driven shaft 520 extends in the up-down direction and is coaxially connected with the driven piece 532. The driving piece 531 and the driven piece 532 are both disc structures with the axis extending in the up-down direction. The connecting rod 533 extends in the horizontal direction. The opposite ends of the connecting rod 533 are respectively hinged to the driving piece 531 and the driven piece 532 through two hinge shafts. The hinge shafts are respectively arranged in parallel with the axis of the driving piece 531 and the axis of the driven piece 532.

[0051] In this way, the driving shaft 510 and the driving piece 531 form a crank, the driven shaft 520 and the driven piece 532 form a rocker, and the connecting rod 533 is hinged to the crank and the rocker as a connecting rod, so as to form a crank rocker mechanism for converting the rotary motion of the rotating motor 410 into reciprocating rotary motion, and realize the reciprocating rotary motion of the turntable 200.

[0052] ​It can be understood that in order to improve production efficiency, the clamp mechanism 110 is provided with a plurality of and arranged at intervals in the first direction, that is, a plurality of turntables 200 are arranged at intervals in the first direction, as shown in Figure 1 Correspondingly, the driven shaft 520 is provided with a plurality of and connected with the plurality of turntables 200 one by one, that is, a plurality of driven shafts 520 are arranged at intervals in the first direction, and the adjacent two driven shafts 520 are drivingly connected.

[0053] In this way, the driving shaft 510 can be drivingly connected with only one of the driven shafts 520. When the rotating motor 410 starts, the rotating motor 410 drives the driving shaft 510 to rotate, so that the driven shaft 520 drivingly connected with the driving shaft 510 performs reciprocating rotation. Since the adjacent driven shafts 520 are drivingly connected, all the driven shafts 520 and all the turntables 200 simultaneously perform reciprocating rotation, so that the torsion actuating device 100 can repeatedly zoom a plurality of zoom lenses 900 at a time, further improving production efficiency.

[0054] In the embodiment, the rotating motor 410 is located to the right of the plurality of clamp mechanisms 110, that is, the driving shaft 510 is located to the right of the plurality of driven shafts 520. The driving shaft 510 is drivingly connected with the driven shaft 520 located at the rightmost position, so that the connecting piece 530 between the driving shaft 510 and the driven shaft 520 does not interfere with the transmission structure between the other two adjacent driven shafts 520. Moreover, since the driven shaft 520 located at the rightmost position is connected with the connecting piece 530 and the transmission structure, the connecting piece 530 and the transmission structure are laid at intervals in the up-down direction to avoid interference.

[0055] Similarly, since the driven shaft 520 located in the middle has a transmission structure with the driven shaft 520 adjacent to the left, and has a transmission structure with the driven shaft 520 adjacent to the right, the two transmission structures connected to the same transmission shaft are laid at intervals in the up-down direction.

[0056] In the embodiment, the first direction is the left-right direction.

[0057] It can be understood that since the positioning mechanism 300 and the frame structure 700 are connected, they are relatively fixed. Therefore, the turntable 200 or the driven shaft 520 is rotationally connected to the frame structure 700, so that the turntable 200 can obtain support through the frame structure 700 and does not affect the rotation of the turntable 200 relative to the positioning mechanism 300. In the embodiment, the driven shaft 520 is rotationally connected to the frame structure 700 through a bearing.

[0058] In some embodiments, a transmission structure of a rack and pinion is used between the two adjacent driven shafts 520. Specifically, each driven shaft 520 is connected with a gear, and a rack extends in the first direction and is meshingly connected with a plurality of gears, so that the plurality of driven shafts 520 synchronously perform reciprocating rotation.

[0059] In the embodiment, the transmission structure is a synchronous belt assembly 600, i.e. a synchronous belt assembly 600 is arranged between the two adjacent driven shafts 520, as shown in Figure 2 and Figure 3 The synchronous belt assembly 600 comprises a synchronous belt 610 and two synchronous pulleys 620, the two adjacent driven shafts 520 are connected with the two synchronous pulleys 620 respectively, and the synchronous belt 610 is arranged around the two synchronous pulleys 620. Through the transmission of the synchronous belt 610, the two adjacent driven shafts 520 are synchronously reciprocatingly rotated.

[0060] It can be understood that each synchronous belt assembly 600 is matched with a tightness adjusting assembly 630, as shown in Figure 2 Specifically, the tightness adjusting assembly 630 comprises a flat pulley 631 and an adjusting block 632, the flat pulley 631 is rotationally connected to the upper side of the adjusting block 632 along the up-down rotating shaft 633, and the flat pulley 631 abuts against the synchronous belt 610. When the synchronous belt 610 transmits the rotating motion of one of the synchronous pulleys 620 to the other synchronous pulley 620, the flat pulley 631 abutting against the synchronous belt 610 rotates along the up-down rotating shaft 633, so that the flat pulley 631 does not interfere with the transmission of the synchronous belt 610.

[0061] It can be understood that the adjusting block 632 and the frame structure 700 are slidingly connected in the second direction, which is the horizontal direction perpendicular to the first direction, i.e. the front-rear direction. By adjusting the front-rear position of the flat pulley 631, the position of the flat pulley 631 abutting against the synchronous belt 610 is adjusted, so that the tightness of the synchronous belt 610 is adjusted, and stable transmission of the synchronous belt 610 to the two synchronous pulleys 620 is ensured. The adjusting block 632 and the frame structure 700 are connected and fixed by the locking structure, so as to fix the position of the flat pulley 631 relative to the frame structure 700 after sliding, and ensure that the flat pulley 631 is always in the state of abutting against the synchronous belt 610, so that the synchronous belt 610 is in a stable transmission state.

[0062] In the embodiment, the locking structure is a locking bolt 635, and the bottom of the adjusting block 632 is provided with a locking screw hole 634 corresponding to the locking bolt 635. The bottom of the frame structure 700 is provided with an adjusting hole 750 extending in the second direction, and the locking bolt 635 is threadedly connected in the locking screw hole 634 after penetrating the adjusting hole 750, as shown in Figure 3 When the locking bolt 635 is tightened in the locking screw hole 634, the adjusting block 632 is relatively fixed with the frame structure 700; when the locking bolt 635 is loosened relative to the adjusting block 632, the locking bolt 635 can drive the adjusting block 632 to slide in the second direction, and the front-rear position of the flat pulley 631 is adjusted.

[0063] Further, the adjusting hole 750 is a stepped slot, so that the head of the locking bolt 635 is hidden in the adjusting hole 750, and the bottom surface of the frame structure 700 is smooth and stable.

[0064] It can be understood that the power mechanism 400 further comprises a coupling 420, as shown in the figure. Specifically, the output end of the rotating motor 410 is downwardly output and connected with the upper end of the coupling 420, the lower end of the coupling 420 is connected and fixed with the upper end of the driving shaft 510, and the coupling 420 is used for transmitting the power and torque output by the rotating motor 410 to the driving shaft 510. The driving shaft 510 is rotatably connected to the upper end surface of the frame structure 700 through a bearing. Figure 2

[0065] It can be understood that the outer end surface of the frame structure 700 is provided with a control mechanism. The control mechanism comprises a switch 810, a speed regulator 820 and a timer 830, as shown in the figure. The switch 810 is electrically connected with the rotating motor 410, and workers can control the on-off of the rotating motor 410 through the switch 810. The speed regulator 820 is electrically connected with the rotating motor 410, and workers can drive the current through the speed regulator 820, so as to control the running speed of the rotating motor 410. The timer 830 is electrically connected with the rotating motor 410, and workers can set the working time of the rotating motor 410 through the timer 830, and when the rotating motor 410 runs to the working time, the timer 830 automatically closes the rotating motor 410, without the need for workers to manually close, and workers can orderly take out the processed zoom lens 900. Figure 1

[0066] It can be understood that the rotating table 200 comprises a support table 210, a support column 220 and a rotating table 230 connected in sequence from top to bottom, as shown in the figure. The roller 910 of the zoom lens 900 is placed downwardly into the rotating table 200, and the upper end surface of the support table 210 supports the roller 910 of the zoom lens 900. The upper end surface of the support table 210 is provided with at least two opposite limiting blocks 240, the limiting blocks 240 are screw-connected with the support table 210, and the roller 910 is clamped between the two limiting blocks 240 from top to bottom, so as to prevent the roller 910 from being displaced. When the rotating table 200 performs reciprocating rotary motion, the roller 910 is driven to perform reciprocating rotary motion relative to the lens barrel 920. The lower end of the rotating table 230 is coaxially connected with the upper end of the driven shaft 520, so that the driven shaft 520 drives the rotating table 200 to perform reciprocating rotary motion. Figure 6

[0067] In some embodiments, the upper end surface of the support table 210 is respectively provided with two limiting blocks 240 along the front-rear direction and the left-right direction, so that the roller 910 is stably clamped in the four limiting blocks 240.

[0068] In this embodiment, the limiting blocks 240 are provided with two and are oppositely arranged along the left-right direction, as shown in the figure.​​​Figure 6 As shown.

[0069] Further, the two limit blocks 240 arranged oppositely can slide on the support table 210 in a connecting mode of the adjusting block 632 and the locking bolt 635, so as to facilitate the adjustment of the interval between the two limit blocks 240 according to the size of the lens flange.

[0070] It can be understood that, as shown, Figure 5 The positioning mechanism 300 includes a fixed support 310, a fixed bottom plate 320 and a positioning ring 330. The fixed support 310 extends in the up-down direction and its opposite ends are connected with the fixed bottom plate 320 and the upper end surface of the frame structure 700 respectively. The positioning ring 330 is provided with a clamping groove 331 for clamping the lens barrel 920 of the zoom lens 900. The fixed bottom plate 320 and the positioning ring 330 are detachably connected, so as to avoid the interference of the positioning ring 330 with the putting-in or taking-out of the zoom lens 900. The positioning ring 330 is provided with a clamping groove 331 for clamping the lens barrel 920 of the zoom lens 900.

[0071] In this way, when the zoom lens 900 is put into the clamp mechanism 110, the limit block 240 on the turntable 200 clamps the roller 910 of the zoom lens 900. When the rotating motor 410 is started, the driving shaft 510 drives the multiple driven shafts 520 through the connecting member 530 and the multiple synchronous belt assemblies 600, so as to drive the multiple rollers 910 to make reciprocating rotary motion respectively. Since the fixed bottom plate 320 is connected with the frame structure 700 through the fixed support 310, and the positioning ring 330 connected with the fixed bottom plate 320 clamps the lens barrel 920 of the zoom lens 900, therefore, the multiple lens barrels 920 are in a static state, simulating the manual repeated rotation of the zoom lens 900 by the worker, so as to repeatedly grind the zoom lens 900, release the lens torque, and thus reduce the jerk feeling generated during zooming.

[0072] In this embodiment, the upper end surface of the fixed bottom plate 320 is provided with a pin 321, and the positioning ring 330 is provided with a pin hole 332 corresponding to the pin 321. The positioning ring 330 is located above the fixed bottom plate 320, and the pin 321 penetrates into the pin hole 332, so as to relatively fix the positioning ring 330 and the fixed bottom plate 320, as shown. Figure 5 The worker can directly take out the positioning ring 330 upward, and then take out or put in the zoom lens 900.

[0073] It can be understood that the number and position of the pin 321 correspond to the number and position of the pin hole 332 respectively. In this embodiment, the fixed bottom plate 320 is provided with two pins 321 arranged at a left-right interval, and the positioning ring 330 is provided with two pin holes 332 arranged at a left-right interval correspondingly, as shown. Figure 5

[0074] ​In the embodiment, the frame structure 700 comprises a mounting cavity 730, the transmission mechanism 500 and the plurality of synchronous belt assemblies 600 are hidden in the mounting cavity 730, as shown in Figure 2 and Figure 3 .

[0075] It can be understood that the frame structure 700 comprises six plate bodies 710 and a plurality of support columns 720, the six plate bodies 710 surround to form a cuboid-shaped frame structure 700, an internal of the frame structure 700 forms a cuboid-shaped mounting cavity 730, the plurality of support columns 720 extend along the up-down direction and connect the plate body 710 at the upper side and the plate body 710 at the lower side, so that the frame structure 700 can stably bear the clamp mechanism 110 and the transmission mechanism 500 and the like, as shown in Figure 2 and Figure 3 .

[0076] It can be understood that the transmission mechanism 500 and the plurality of synchronous belt assemblies 600 are hidden in the mounting cavity 730, the frame structure 700 provides a supporting action and a protection action for the transmission mechanism 500 and the plurality of synchronous belt assemblies 600, so as to avoid that dust, flying insects and the like affect the transmission efficiency of the transmission mechanism 500 and the plurality of synchronous belt assemblies 600.

[0077] Further, the upper end surface of the frame structure 700 is further provided with a support plate 740 for supporting the rotating motor 410, as shown in Figure 2 .
