DETAILED DESCRIPTION

[0043] The following will be combined with the drawings Figures 1-6 ​​Further details of the application are described below.

[0044] Referring to Figure 1 and Figure 2 The embodiment of the application discloses a high-precision gear ring rotary driving device, which is used in cooperation with an automatic conveying device for conveying a device assembly cylinder structure and an automatic assembly device for assembling a servo driver on the device assembly cylinder structure. After the automatic conveying device sends the device assembly cylinder structure to the high-precision gear ring rotary driving device in a position state to be clamped, the high-precision gear ring rotary driving device clamps the device assembly cylinder structure and controls the device assembly cylinder structure to move to a position to be assembled with the servo driver, then the high-precision gear ring rotary driving device controls the device assembly cylinder structure to rotate to the position state to be assembled with the servo driver, and the automatic assembly device assembles the servo driver on the device assembly cylinder structure. In the embodiment, the automatic conveying device is preferably an AGV (Automatic Guided Vehicle) trolley, and the automatic assembly device is preferably a program-controlled robot. Since the AGV trolley and the program-controlled robot are both common prior art, they are not described here, and are omitted in the drawings.

[0045] The high-precision gear ring rotary driving device comprises a rack 1, a base 2, two fixing seats 3, a plurality of first driving assemblies 4, a plurality of second driving assemblies 5, a rotating assembly 6 and two clamps 7.

[0046] The rack 1 is used for providing support for the high-precision gear ring rotary driving device, the rack 1 is vertically installed on the ground, and the bottom of the rack 1 is fixedly connected with the ground.

[0047] In the embodiment, the rack 1 is preferably a cuboid structure, and the height direction of the rack 1 is perpendicular to the ground after the rack 1 is installed on the ground.

[0048] The base 2 is installed on one side of the rack 1, and the base 2 is slidingly connected with the rack 1 in the vertical direction. The plurality of first driving assemblies 4 are installed on the top of the rack 1 and are used for controlling the base 2 to slide relative to the rack 1 in the vertical direction. In the embodiment, the high-precision gear ring rotary driving device preferably comprises two first driving assemblies 4, and the first driving assembly 4 is preferably a pneumatic cylinder. The piston rod of the first driving assembly 4 is fixedly connected with the base 2 above the base 2, so as to control the base 2 to slide relative to the rack 1 in the vertical direction. In other embodiments, the first driving assembly 4 can also be a lead screw transmission structure driven by a motor.

[0049] In the embodiment, the base 2 is preferably a rectangular plate structure, and after the base 2 is installed on the rack 1, the length direction of the base 2 is parallel to the length direction of the rack 1, and the width direction of the base 2 is parallel to the sliding direction of the base 2.

[0050] Further, two rails are fixedly installed on the rack 1, and the length direction of the rails is parallel to the height direction of the rack 1. The two rails are matched with the base 2, and are used to guide the base 2 to slide relative to the rack 1 along the vertical direction, thereby improving the stability of the base 2 sliding driven by the first driving assembly 4.

[0051] The process of the first driving assembly 4 driving the base 2 to slide relative to the rack 1 has a limitation, that is, when the first driving assembly 4 drives the base 2 to slide downward to the limit position or before the limit position, the equipment assembly cylinder structure transported by the automatic transportation equipment is just located at the position to be clamped for the high-precision gear ring rotary driving device.

[0052] The fixed seat 3 is installed on the side of the base 2 away from the rack 1, and the two fixed seats 3 are respectively installed on the two ends of the base 2 in the length direction. A plurality of second driving assemblies 5 are installed on the base 2 and located between the two fixed seats 3. In this embodiment, the high-precision gear ring rotary driving device preferably includes one second driving assembly 5.

[0053] In this embodiment, the fixed seat 3 is a plate-shaped structure as a whole, and is installed on the base 2 in a vertical state.

[0054] The second driving assembly 5 includes a rotary block 52, two connecting rods 53, and a driving motor 51.

[0055] The rotary block 52 is rotationally installed on the side of the base 2 away from the rack 1. The rotation axis of the rotary block 52 is horizontal and perpendicular to the sliding direction of the base 2, and the installation position of the rotary block 52 on the base 2 is in the middle.

[0056] The two connecting rods 53 are respectively located between the rotary block 52 and the two fixed seats 3. The two ends of the connecting rod 53 are respectively hinged to the rotary block 52 and the adjacent fixed seat 3, and the rotation axis of the connecting rod 53 and the rotary block 52 and the rotation axis of the connecting rod 53 and the fixed seat 3 are parallel to the rotation axis of the rotary block 52.

[0057] The driving motor 51 is fixedly installed on the side of the base 2 close to the rack 1. The rack 1 has a space for the driving motor 51 to be installed, and the space is also sufficient for the driving motor 51 to move when the base 2 slides along the vertical direction. In this embodiment, the driving motor 51 is preferably a servo motor 61. The output shaft of the driving motor 51 is fixedly connected with the rotary block 52 through the base 2, and is used to drive the rotary block 52 to rotate relative to the base 2.

[0058] The fixed seat 3 is in sliding connection with the base 2, and the sliding direction of the fixed seat 3 is parallel to the length direction of the base 2. When the rotating block 52 rotates, the two fixed seats 3 can be driven to slide relative to the base 2 through the two connecting rods 53. At this time, the two fixed seats 3 slide relative to the base 2 in opposite directions and synchronously, and the distance between the two fixed seats 3 and the rotating block 52 remains equal.

[0059] Further, preferably, two tracks are also fixedly installed on the base 2, and the length direction of the tracks is parallel to the length direction of the base 2. The two tracks are matched with the fixed seats 3 and are used to guide the fixed seats 3 to slide relative to the base 2 in the horizontal direction, thereby improving the stability of the second driving assembly 5 in driving the fixed seats 3 to slide.

[0060] The process of the second driving assembly 5 driving the two fixed seats 3 to slide relative to the base 2 in opposite directions synchronously also has a limit, that is, when the two fixed seats 3 slide relative to each other to the limit position or not to the limit position, the equipment assembly cylinder structure can be clamped and positioned between the two fixed seats 3 at this time, so as to realize the clamping of the high-precision gear ring rotary driving device to the equipment assembly cylinder structure.

[0061] When the high-precision gear ring rotary driving device clamps the equipment assembly cylinder structure, the two fixed seats 3 will be affected by the reaction force of the clamping force. In order to improve the stability of the high-precision gear ring rotary driving device in clamping the equipment assembly cylinder structure, the high-precision gear ring rotary driving device further comprises a plurality of extendable auxiliary assemblies 8.

[0062] The auxiliary assembly 8 is horizontally installed between the two fixed seats 3, so that an additional connection relationship is formed between the two fixed seats 3, thereby improving the stability of the relative position between the two fixed seats 3 when the two fixed seats 3 clamp the equipment assembly cylinder structure. In the embodiment, preferably, the auxiliary assembly 8 is also a pneumatic cylinder, and one end of the cylinder body is fixedly connected with the top of one fixed seat 3, and the other end of the piston rod is fixedly connected with the top of the other fixed seat 3.

[0063] The auxiliary assembly 8 is in signal connection with the second driving assembly 5. In the process of the second driving assembly 5 driving the two fixed seats 3 to slide in opposite directions synchronously, the length of the auxiliary assembly 8 will change adaptively, and when the second driving assembly 5 stops driving the two fixed seats 3 to slide, the length of the auxiliary assembly 8 will also be fixed, thereby improving the stability of the relative position between the two fixed seats 3 at this time.

[0064] Referring to Figure 1 and Figure 3 , the rotating assembly 6 comprises a servo motor 61, a driving gear 62, a driven gear ring 63, a follower ring 64, and a plurality of limit pieces 65.

[0065] The servo motor 61 is fixedly installed on one fixed seat 3 and located on the side of the fixed seat 3 away from the other fixed seat 3. The driving gear 62 is located on the side of the fixed seat 3 close to the other fixed seat 3, the output shaft of the servo motor 61 is fixedly connected with the driving gear 62, the servo motor 61 can drive the driving gear 62 to rotate, and the rotation axis of the driving gear 62 is parallel to the sliding direction of the fixed seat 3.

[0066] The driven gear ring 63 is installed on the side of the fixed seat 3 close to the other fixed seat 3 where the servo motor 61 is located and located on the side of the driving gear 62 away from the base 2, and the driven gear ring 63 is engaged with the driving gear 62. In this embodiment, the number of teeth and the radial size of the driven gear ring 63 are preferably much larger than the number of teeth and the radial size of the driving gear 62, and the number of teeth and the radial size of the driving gear 62 and the driven gear ring 63 are not further limited, and in actual application, they can be adjusted according to the size of the device assembly cylinder structure.

[0067] The follower ring 64 is installed on the other fixed seat 3 and located on the side of the fixed seat 3 close to the fixed seat 3 where the servo motor 61 is located. In this embodiment, the driven gear ring 63 and the follower ring 64 are preferably both annular plate structures, the axis of the driven gear ring 63 and the axis of the follower ring 64 are both parallel to the sliding direction of the fixed seat 3, and the axis of the driven gear ring 63 and the axis of the follower ring 64 coincide.

[0068] Referring to Figure 1 and Figure 3 , the plurality of limiting members 65 are respectively installed on the two fixed seats 3.

[0069] Referring to Figure 5 and Figure 6 , after the plurality of limiting members 65 are installed on the fixed seat 3 where the driven gear ring 63 is located, the plurality of limiting members 65 are all located on the inner side of the driven gear ring 63, the driven gear ring 63 extends an annular guide rail 631 towards the inner side of itself, and the axis of the annular guide rail 631 coincides with the axis of the driven gear ring 63. The limiting member 65 has a groove 651 matched with the annular guide rail 631, the annular guide rail 631 is simultaneously clamped and matched with the groove 651 of the plurality of limiting members 65, at this time, the plurality of limiting members 65 can not only support the driven gear ring 63, but also guide the driven gear ring 63 to stably rotate around its axis, at this time, the rotation axis of the driven gear ring 63 coincides with its axis, and at this time, there is a gap between the driven gear ring 63 and the corresponding fixed seat 3. In this embodiment, the cross section of the annular guide rail 631 is preferably triangular; in other embodiments, the shape of the annular guide rail 631 can also be different.

[0070] When the annular guide rail 631 is in clamping fit with the groove 651 on the limiting piece 65, the annular guide rail 631 is in contact with the groove wall of the groove 651. At this time, the limiting piece 65 can limit the displacement of the driven gear ring 63 in the axial direction and the radial direction during rotation, so that the driven gear ring 63 can have better positioning accuracy in the circumferential direction relative to the fixed seat 3.

[0071] With reference to Figure 1 and Figure 6 , after the limiting pieces 65 are installed on the fixed seat 3 where the follow-up ring 64 is located, the limiting pieces 65 are all located on the outer side of the follow-up ring 64, and the outer side end of the follow-up ring 64 can be in clamping fit with the grooves 651 of the limiting pieces 65 at the same time. Similarly, at this time, the limiting pieces 65 can not only support the follow-up ring 64, but also guide the follow-up ring 64 to stably rotate around the axis line thereof, and at this time, the rotation axis line of the follow-up ring 64 coincides with the axis line thereof.

[0072] Similarly, when the outer side end of the follow-up ring 64 is in clamping fit with the groove 651 on the limiting piece 65, the follow-up ring 64 is in contact with the groove wall of the groove 651. At this time, the limiting piece 65 can limit the displacement of the follow-up ring 64 in the axial direction and the radial direction during rotation, so that the follow-up ring 64 can have better positioning accuracy in the circumferential direction relative to the fixed seat 3.

[0073] With reference to Figure 2 and Figure 3 When the equipment assembly cylinder structure is in a clamped state, the servo motor 61 drives the driving gear 62 to rotate, the driving gear 62 drives the driven gear ring 63 to rotate, and the follow-up ring 64 rotates synchronously with the driven gear ring 63 through the equipment assembly cylinder structure, so that the rotating assembly 6 can control the rotation adjustment position state of the equipment assembly cylinder structure. Among them, the servo motor 61 can control the rotation of the driven gear ring 63 with high precision through the driving gear 62, realizing tooth rotation.

[0074] The through holes 31 are formed in the two fixed seats 3, and the cross section of the through hole 31 is preferably circular. After the driven gear ring 63 is installed on one fixed seat 3, the axis line of the driven gear ring 63 coincides with the axis line of the through hole 31 on the corresponding fixed seat 3; after the follow-up ring 64 is installed on the other fixed seat 3, the axis line of the follow-up ring 64 coincides with the axis line of the through hole 31 on the corresponding fixed seat 3. When the equipment assembly cylinder structure is clamped between the two fixed seats 3, the through hole 31 can provide space for the servo driver to be assembled inside the equipment assembly cylinder structure.

[0075] With reference to Figure 3 and Figure 5Further, preferably, the limiting pieces 65 are rotationally connected with the fixed seats 3, and the rotation axes of the limiting pieces 65 are parallel to the rotation axis of the driven gear ring 63. When the servo motor 61 drives the driving gear 62 to rotate and drive the driven gear ring 63 to rotate, the limiting pieces 65 will rotate under the friction between the limiting pieces 65 and the annular guide rail 631, so as to reduce the resistance of the limiting pieces 65 to the rotation of the driven gear ring 63, and make the rotation process of the driven gear ring 63 more smooth. In the embodiment, preferably, the limiting pieces 65 are rollers.

[0076] With reference to Figure 1 Similarly, when the follower ring 64 rotates synchronously with the driven gear ring 63 through the equipment assembly cylinder structure, the limiting pieces 65 will also rotate under the friction between the limiting pieces 65 and the outer side end of the follower ring 64, so as to also reduce the resistance of the limiting pieces 65 to the rotation of the follower ring 64, and make the rotation process of the follower ring 64 more smooth.

[0077] With reference to Figure 1 and Figure 4 Further, preferably, six limiting pieces 65 are installed on each of the two fixed seats 3, and the six limiting pieces 65 are distributed in a circumferential array on the fixed seat 3 with the axis of the through hole 31 as the axis. This makes the limiting effect of the six limiting pieces 65 on the annular guide rail 631 more evenly distributed on the annular guide rail 631, and also makes the limiting effect of the six limiting pieces 65 on the follower ring 64 more evenly distributed on the follower ring 64, thereby reducing the probability of local damage of the annular guide rail 631 and the follower ring 64 due to uneven stress.

[0078] With reference to Figure 1 and Figure 3 Further, in the process of the limiting pieces 65 rotating with the driven gear ring 63 and rotating with the follower ring 64, the annular guide rail 631 and the limiting pieces 65 and the follower ring 64 and the limiting pieces 65 will all be worn to different degrees, which will affect the control accuracy of the subsequent rotating assembly 6 in controlling the rotation of the equipment assembly cylinder structure.

[0079] Therefore, preferably, the limiting pieces 65 are detachably connected with the fixed seats 3 by means of bolts. When the limiting pieces 65 are affected in positioning and limiting due to wear, the above problems can be solved by replacing the limiting pieces 65 with new ones.

[0080] With reference to Figure 1 and Figure 6 Further, preferably, abutting pads 66 for replacing the contact between the limiting pieces 65 and the annular guide rail 631 and the follower ring 64 are detachably connected with the limiting pieces 65. The abutting pads 66 are elastic and have a certain elastic deformation capacity. In the embodiment, preferably, the abutting pads 66 are made of rubber material, and the abutting pads 66 are detachably connected with the limiting pieces 65 in a sleeved manner.

[0081] When the abutting pad 66 is connected with the limiting piece 65, the abutting pad 66 can cover the groove wall of the groove 651 and form a new groove 651 for the clamping cooperation of the annular guide rail 631 and the outer end of the follower ring 64, and at this time, the annular guide rail 631 and the outer end of the follower ring 64 are clamped and cooperated with the groove 651, and the abutting pad 66 is extruded to cause elastic deformation. The annular guide rail 631 and the follower ring 64 can keep in contact with the limiting piece 65 through the abutting pad 66, so that the limiting piece 65 can further stably limit the driven gear ring 63 and the follower ring 64.

[0082] During the use of the rotating assembly 6, the abutting pad 66 can reduce the wear between the annular guide rail 631, the follower ring 64 and the limiting piece 65. When the positioning and limiting effects of the limiting piece 65 are affected due to the wear of the abutting pad 66, the above problems can be solved by replacing the new abutting pad 66.

[0083] Referring to Figure 1 and Figure 3 , the two clamps 7 correspond to the driven gear ring 63 and the follower ring 64 one by one, and the two clamps 7 are located between the driven gear ring 63 and the follower ring 64. When the device assembly cylinder structure is clamped by the two fixed bases 3, the clamp 7 will replace the driven gear ring 63 and the follower ring 64 to directly contact and abut against the device assembly cylinder structure, so as to reduce the wear of the driven gear ring 63 and the follower ring 64 caused by the reaction force of the clamped device assembly cylinder structure.

[0084] In the embodiment, in order to protect the driven gear ring 63 and the follower ring 64, the side of the driven gear ring 63 away from the corresponding fixed base 3 and the side of the follower ring 64 away from the corresponding fixed base 3 are both fixedly installed with an annular reinforcing plate 9, the axis of the reinforcing plate 9 coincides with the axis of the driven gear ring 63, and the corresponding clamp 7 is installed on the reinforcing plate 9, so as to further reduce the wear of the driven gear ring 63 and the follower ring 64 caused by the clamping of the device assembly cylinder structure.

[0085] Further, the annular guide rail 631 is located on the driven gear ring 63 away from the clamp 7 along the axis direction of the driven gear ring 63, and there is a spacing between the annular guide rail 631 and the clamp 7, which can reduce the probability that the reaction force of the clamped device assembly cylinder structure is transmitted to the annular guide rail 631 through the clamp 7 and the reinforcing plate 9 in sequence, so as to further reduce the loss of the annular guide rail 631 during use and prolong the service life of the annular guide rail 631.

[0086] The clamp 7 is detachably connected with the reinforcing plate 9. When the clamp 7 is used for a period of time and appears a certain degree of wear, the clamping effect of the high-precision gear ring rotary driving device on the equipment assembly cylinder structure will be affected. At this time, the above problem can be solved by disassembling and replacing a new clamp 7.

[0087] The clamp 7 includes a plurality of tool plates 71. In the embodiment, preferably, the clamp 7 includes three tool plates 71, and the three tool plates 71 are distributed in a circular array on the reinforcing plate 9 with the axis of the reinforcing plate 9 as the axis.

[0088] The clamp 7 also includes a plurality of positioning pins 72. In the embodiment, preferably, the clamp 7 adjacent to the driven gear ring 63 includes two positioning pins 72, and the clamp 7 adjacent to the follower ring 64 includes three positioning pins 72. The plurality of positioning pins 72 are distributed in a circular array on the reinforcing plate 9 with the axis of the reinforcing plate 9 as the axis.

[0089] In addition, in the embodiment, preferably, the tool plate 71 and the positioning pin 72 are detachably connected with the reinforcing plate 9 by the bolt fixing mode.

[0090] Among them, the side of the tool plate 71 adjacent to the driven gear ring 63 close to the axis of the reinforcing plate 9 is provided with an avoiding groove 711 matched with the protruding structure at the end of the equipment assembly cylinder structure; the structure of the plurality of positioning pins 72 is matched with the positioning hole provided at the end of the equipment assembly cylinder structure.

[0091] In actual application, the position and number of the tool plate 71 included in the clamp 7, the position and number of the positioning pin 72, and whether the avoiding groove 711 is provided on the tool plate 71 can be adjusted according to the structure of the actual equipment assembly cylinder structure and the clamping requirement.

[0092] When the equipment assembly cylinder structure is clamped between the two fixed seats 3, the two reinforcing plates 9 are in contact with the two ends of the equipment assembly cylinder structure, respectively, and the protruding structures at the two ends of the equipment assembly cylinder structure are in clamping cooperation with the avoiding grooves 711 on different tool plates 71, and different positioning pins 72 are also in plug-in cooperation with the positioning holes at the ends of the equipment assembly cylinder structure, thereby improving the clamping effect of the clamp 7 on the equipment assembly cylinder structure, i.e., improving the position stability of the equipment assembly cylinder structure after being clamped, and further improving the position accuracy when the subsequent rotary assembly 6 drives the equipment assembly cylinder structure to rotate to change the position state.

[0093] The implementation principle of the high-precision gear ring rotary driving device in the embodiment is as follows:

[0094] The automatic conveying device sends the equipment assembly cylinder structure to the high-precision gear ring rotary driving device, the high-precision gear ring rotary driving device controls a plurality of first driving assemblies 4 and a plurality of second driving assemblies 5 to clamp and move the equipment assembly cylinder structure to a position to be assembled with the servo driver through the clamp 7; then the rotary assembly 6 controls the equipment assembly cylinder structure to rotate accurately to the position to be assembled with the servo driver with high precision, and the automatic assembly equipment completes the assembly of the servo driver on the equipment assembly cylinder structure; the above steps are repeated until the four servo drivers are all assembled on the equipment assembly cylinder structure.

[0095] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, so: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
