[0001] The utility model relates to the technical field of bolt locking, in particular to an automatic flipping bolt locking device. Background Art

[0002] A product is composed of several parts and components. According to the specified technical requirements, the labor process of joining several parts into components or joining several parts and components into a product is called assembly. Assembly must have two basic conditions: positioning and clamping. To determine the correct positioning of the parts and fix the positioned parts. Usually, the fixing method of parts is bolt fixing. Currently, many assemblies are manually operated by workers. First, the bolts are placed into the bolt holes of the product, and then tightened with a screwdriver.

[0003] In the manual method, when bolt-locking and fixing two parts as shown in the appendix Figure 1 、 2 , first, the bolt holes 13 of the first workpiece 11 and the second workpiece 12 need to be aligned, and then the bolts are placed in the corresponding bolt holes 13 and tightened to complete the fixing. When there are many bolt holes, the above manual operation method has a low overall efficiency, and the force of the worker is uneven during the operation, which easily leads to the situation that the product is not tightened or over-tightened, affecting the product quality.

[0004] During the bolt-locking process, sometimes it is necessary to flip the parts and components to lock the bolts on different surfaces. When the first workpiece 11 and the second workpiece 12 in the appendix Figure 1 、 2 are parts and components with a large volume and large weight, the manual flipping operation is difficult, the overall working intensity is high, the efficiency is low, and there is a certain danger.

In this way, the placement positions of the first workpiece and the second workpiece can be positioned through the positioning groove, so that the bolt holes on the two are aligned. The bolt hole at the lower end of the second workpiece can be exposed by using the installation through hole. On the one hand, when screwing the bolt downward from the first workpiece, the bolt head can be prevented from contacting the working plate, causing assembly failure. On the other hand, when it is necessary to turn over and screw the bolt from the second workpiece to the first workpiece, the bolt hole on the end surface of the second workpiece facing away from the first workpiece can be exposed, facilitating bolt locking.

[0019] By using the stopping and clamping mechanism, the first workpiece and the second workpiece can be clamped on the working plate. On the one hand, it can prevent shaking during the process of locking the bolt. On the other hand, it can prevent the workpiece from falling off after turning over.

[0020] With the locking device, the locking gun can be driven by a three-dimensional driving mechanism and moved to the position of the locking bolt to complete the extraction of the locking bolt. Then, it is moved to the position of the bolt hole under the drive of the three-dimensional driving mechanism to complete the bolt locking, realizing automatic operation. On the one hand, the assembly efficiency is improved, and on the other hand, it can ensure that the locking bolt is tightened in the corresponding bolt hole with uniform and the same force, guaranteeing the product quality.

[0021] (2) The use of the backing plate can make the clamping force of the stop clamping mechanism acting on the first workpiece evenly distributed, avoiding the offset between the first workpiece and the second workpiece and ensuring accurate positioning. Description of the Drawings

Detailed implementation manners

[0040] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application: Specific Embodiment 1:

[0042] Referring to Figures 1 to 14 , an automatic flipping bolt locking device (hereinafter referred to as the bolt locking device) of the present utility model includes a frame 1. The frame 1 is integrally in a frame structure. A control panel 2 is arranged outside the frame 1, and an operation part 3 is arranged in the upper middle part inside the frame 1. The operation part 3 includes an operation table 4 horizontally fixed inside the frame 1, and a flipping tooling 5 and a locking tooling are arranged on the operation table 4.

[0043] Among them, the flipping tooling 5 includes a rotating mechanism 51. A working plate 56 is rotatably arranged on the rotating mechanism 51. The rotation axis of the working plate 56 extends horizontally. A positioning groove 57 adapted to the contour of the workpiece is arranged on the end face of the working plate 56. An installation through hole 58 corresponding to the bolt hole 13 of the workpiece is arranged on the bottom of the positioning groove 57. A blocking and clamping mechanism 6 is arranged on the working plate 56. The blocking and clamping mechanism 6 is used to clamp and fix the workpiece to prevent the workpiece from falling off when following the working plate 56 to flip. The locking tooling includes a locking bolt 91, a three-dimensional driving mechanism and a locking gun 92. Driven by the three-dimensional driving mechanism, the locking gun 92 moves to the position of the locking bolt 91, extracts the locking bolt 91, and then the locking gun 92 moves to the position corresponding to the bolt hole 13 of the workpiece under the drive of the three-dimensional driving mechanism. The locking gun 92 locks the locking bolt 91 into the bolt hole 13 of the workpiece to complete the bolt locking.

[0044] In this embodiment, as Figure 1 , 2 shown, the workpiece includes a first workpiece 11 and a second workpiece 12. A plurality of bolt holes 13 are correspondingly arranged on the first workpiece 11 and the second workpiece 12. As Figure 8 , 9 , 10 shown, the size of the positioning groove 57 on the working plate 56 is adapted to the size on the second workpiece 12, and a positioning pin 59 is further arranged on the bottom of the positioning groove 57. A positioning hole is correspondingly arranged on the second workpiece 12. The second workpiece 12 is positioned by using the positioning groove 57 and the positioning pin 59. As Figure 7 shown, on the part of the upper end face of the working plate 56 where the positioning groove 57 is not opened, four blocking blocks 63 are arranged along its circumferential direction. The four blocking blocks 63 respectively block on the four side faces of the first workpiece 11. In this way, the first workpiece 11 is positioned by using the blocking blocks 63. The positioning of the first workpiece 11 and the second workpiece 12 is completed.

[0045] In this embodiment, as Figure 5 , 7 shown, the flipping tooling 5 includes two groups of first support frames 55 arranged at intervals horizontally. Each group of first support frames 55 includes two first support frames 55 arranged at intervals longitudinally. The lower ends of the first support frames 55 are fixed on the workbench 4.

[0046] The rotating mechanism 51 includes a rotating support frame 54 disposed between two first support frames 55 on the same side in the transverse direction. The rotating support frame 54 is fixed to the corresponding first support frame 55 on its side. Thus, two rotating support frames 54 are symmetrically arranged on both sides in the transverse direction. A rotating disk 53 is rotatably mounted on the opposite surfaces of the two rotating support frames 54 respectively, and the rotation axis of the rotating disk 53 extends in the transverse direction. The transverse ends of the working plate 56 are respectively fixedly connected to the two rotating disks 53, so that the working plate 56 can be rotatably arranged, and its rotation axis extends in the transverse direction.

[0047] In this embodiment, the rotating mechanism 51 further includes a rotating motor 52, and the rotating motor 52 is supported and fixed on the workbench 4 through the rotating support frame 54. The rotating motor 52 is connected to one of the rotating disks 53 through a coupling 10, and the rotating motor 52 is used to drive the working plate 56 to rotate, so as to realize flipping. Of course, in other embodiments, the rotating motor 52 can also be directly in non-rotating fit with one of the rotating disks 53, as long as the rotation of the rotating disk 53 can be realized.

[0048] In this embodiment, as Figure 4 , 5 shown, the three-dimensional driving mechanism includes two longitudinal support frames 93 arranged at intervals in the transverse direction, and the length of the longitudinal support frames 93 extends in the longitudinal direction. The flipping tooling 5 is disposed between the two longitudinal support frames 93, and the height of the longitudinal support frames 93 is higher than that of the flipping tooling 5. In the longitudinal direction, the flipping tooling 5 is disposed on one side facing the loading port 101 of the frame 1. A longitudinal driving module 94 is provided on the upper ends of the two longitudinal support frames 93, and a mounting plate 95 is slidably disposed on the longitudinal driving module 94.

[0049] Specifically, the longitudinal driving module 94 includes two longitudinal guide rails 941 symmetrically disposed on the upper ends of the two longitudinal support frames 93. Open-ended blocks (not shown in the figure) are respectively disposed on the transverse sides at the lower end of the mounting plate 95. The opening of the open-ended block extends in the longitudinal direction, and the open-ended block is slidably clamped on the corresponding longitudinal guide rail 941, so as to realize the longitudinal sliding arrangement of the mounting plate 95 on the longitudinal guide rail 941.

[0050] In this embodiment, a transverse driving module 96 is provided on the upper end of the mounting plate 95, and a moving plate 962 is slidably disposed on the transverse driving module 96 in the transverse direction. Specifically, the transverse driving module 96 includes two transverse guide rails 961 symmetrically disposed on the longitudinal sides of the mounting plate 95. Similar to the above, open-ended blocks (not shown in the figure) are respectively disposed on the longitudinal sides at the lower end of the moving plate 962. The opening of the open-ended block extends in the transverse direction, and the open-ended block is slidably clamped on the corresponding transverse guide rail 961, so as to realize the transverse sliding arrangement of the moving plate 962 on the transverse guide rail 961.

[0051] In this embodiment, a linear driving mechanism is further included. The transverse driving module 96 and the longitudinal driving module 94 respectively achieve the longitudinal sliding of the mounting plate 95 and the transverse sliding of the moving plate 962 through the linear driving mechanisms in the corresponding directions. The specific linear driving mechanism can be a lead screw nut mechanism. Of course, in other embodiments, the linear driving mechanism can also be a belt drive mechanism, etc. The specific implementation method and installation method are common knowledge well-known to those skilled in the art and will not be elaborated here.

[0052] In this embodiment, a vertical driving module 97 is provided on the moving plate 962, and the locking gun 92 is slidably arranged vertically on the vertical driving module 97.

[0053] Specifically, in this embodiment, as Figure 4 、 11 、12 show, a hollow cavity 951 extending transversely is provided on the mounting plate 95, and the transverse guide rails 961 are symmetrically arranged on both sides of the hollow cavity 951. The vertical driving module 97 is arranged on the transverse side of the moving plate 962 and is entirely located within the hollow cavity 951.

[0054] Specifically, the vertical driving module 97 includes a vertical mounting frame 971. An installation groove 972 extending vertically is provided inside the vertical mounting frame 971. As Figure 12 shows, the vertical mounting frame 971 is a frame structure, and the inner cavity of the frame structure forms the installation groove 972. A vertical lead screw 973 is rotatably arranged in the installation groove 972, and the upper and lower ends of the vertical lead screw 973 are respectively rotatably arranged on the upper and lower groove walls of the installation groove 972. A vertical motor 976 is provided at the upper end of the vertical mounting frame 971, and the output shaft of the vertical motor 976 extends downward and is connected to the vertical lead screw 973 through a coupling 10. The vertical lead screw 973 can be driven to rotate by the vertical motor 976. Of course, in other embodiments, the output shaft of the vertical motor 976 can also be directly connected to the vertical lead screw 973 as long as the rotation of the vertical lead screw 973 can be achieved.

[0055] In this embodiment, as Figure 11 、 12 shows, a matching moving block 974 is slidably arranged vertically in the installation groove 972. The inner end of the moving block 974 is in threaded cooperation with the vertical lead screw 973, and the other end of the moving block 974 extends out of the installation groove 972 and is connected to the locking gun 92. The size of the moving block 974 is adapted to the size of the installation groove 972. In this way, the rotation of the moving block 974 is restricted by the installation groove 972. The moving block 974 and the vertical lead screw 973 form a lead screw nut mechanism. By rotating the vertical lead screw 973, the moving block 974 is driven to slide vertically, thereby realizing the vertical movement of the locking gun 92. Of course, in other embodiments, a linear cylinder can also be used to drive the locking gun 92 to move vertically. There are many specific implementation methods and will not be limited here.

[0056] In this way, the vertical driving module 94, the horizontal driving module 96, and the vertical driving module 97 can drive the locking gun 92 to move longitudinally, horizontally, and vertically respectively, realizing the movement of the locking gun 92 in three-dimensional directions.

[0057] In this embodiment, the bolt locking device further includes a backing plate tooling. The backing plate tooling includes a backing plate 72 placed on the workbench 4. The backing plate 72 is used to be placed between the workpiece and the stop clamping mechanism 6. The backing plate tooling further includes a backing plate jaw mechanism 79. A lifting mechanism 74 is arranged at the position corresponding to the backing plate jaw mechanism 79 on the moving plate 962. The backing plate jaw mechanism 79 is arranged on the moving plate 962 through the lifting mechanism 74. By using the backing plate 72, the clamping force exerted by the stop clamping mechanism 6 on the first workpiece 11 can be evenly distributed, avoiding the deviation between the first workpiece 11 and the second workpiece 12 and ensuring accurate positioning.

[0058] Specifically, in this embodiment, as Figure 6 shown, the backing plate tooling includes a backing plate support frame 71 fixed on the workbench. One lateral side of the backing plate support frame 71 is the backing plate position, and the backing plate 72 is used to be placed on the backing plate position. The other lateral side of the backing plate support frame 71 is the bolt position 8. The bolt position 8 includes a plurality of through holes adapted to the locking bolts 91. The locking bolts 91 are arranged in the through holes with their large heads facing upward, completing the arrangement of the locking bolts 91.

[0059] In this embodiment, as Figure 13 , 14 shown, the lifting mechanism 74 includes a lifting cylinder 741 arranged at the central position of the upper end of the moving plate 962. The lower end of the lifting cylinder 741 is the output end, and its output end extends downward and passes through the moving plate 962. The backing plate jaw mechanism 79 includes a lifting plate 742 arranged parallel to the lower side of the moving plate 962. The size of the lifting plate 742 is smaller than that of the moving plate 962, and the longitudinal size of the lifting plate 742 is smaller than the longitudinal size of the hollow cavity 951, so that the lifting plate 742 can be driven by the lifting cylinder 741 to pass through the hollow cavity 951 to complete vertical movement and avoid interference.

[0060] The upper end of the lifting plate 742 is connected to the output end of the lifting cylinder 741. The lower end of the lifting plate 742 is provided with an opening and closing mechanism that opens and closes longitudinally. One clamping jaw 792 is arranged at each of the longitudinal two ends of the opening and closing mechanism. Convex blocks 793 are arranged on the opposite sides of the two clamping jaws 792. Clamping jaw holes 73 corresponding to the convex blocks 793 on the clamping jaws 792 are arranged on the longitudinal two sides of the backing plate 72. In this way, the two clamping jaws 792 can clamp the backing plate 72 through the opening and closing mechanism. The backing plate 72 can be lifted and lowered by the lifting cylinder 741, and then the backing plate 72 can be moved above the first workpiece 11 through the horizontal driving module 96 and the longitudinal driving module 94.

[0061] In this embodiment, the opening and closing mechanism is asFigure 14 As shown, there are two opening and closing cylinders 791 arranged vertically at intervals. The output ends of the two opening and closing cylinders 791 extend in opposite directions and are respectively connected to a clamping jaw 792, and the opening and closing actions are completed by the two opening and closing cylinders 791. At one end of the opening and closing cylinder 791 facing away from its output shaft, an opening and closing rod is slidably arranged coaxially. One end of the opening and closing rod facing away from the opening and closing cylinder 791 is connected to the clamping jaw 792 on the other side, and the opening and closing rod is used for cooperation and guiding. Of course, in other embodiments, the opening and closing mechanism can also be a rack and pinion mechanism.

[0062] In this embodiment, preferably, a plurality of guide holes are circumferentially arranged around the axis of the lifting cylinder 741 on the moving plate 962. A guide sleeve 78 is fixedly arranged through the guide holes. A guide rod 77 is slidably arranged in the guide sleeve 78. The lower end of the guide rod 77 is connected to the lifting plate 742 to complete the guiding of the movement of the lifting plate 742 and ensure stability.

[0063] In this embodiment, as Figure 7 shown, the blocking and clamping mechanism 6 includes two blocking motors 61 symmetrically arranged on the longitudinal two sides of the working plate 56. The output shafts of the blocking motors 61 extend vertically away from the positioning groove 57. A blocking arm 62 is non-rotatably installed on the output shaft. The blocking arm 62 is used to block on the end face of the first workpiece 11 to clamp and fix the workpiece. Of course, in other embodiments, the blocking and clamping mechanism 6 can also be a strip-shaped clamping strip. The length of the clamping strip extends longitudinally and its longitudinal two ends are fixed on the working plate 56 by bolts, and the clamping is completed manually.

[0064] In this embodiment, as Figure 11 shown, the locking gun 92 includes a bolt locking gun 921 and a screw locking gun 922. In this way, bolt locking and screw locking can be completed, improving the practicability.

[0065] The working process of this application: The staff first places the second workpiece 12 on the working plate 56, and aligns the installation through hole 58 on the working plate 56 with the positioning pin 59 to the corresponding hole on the second workpiece 12 to complete the installation of the second workpiece 12. Place the first workpiece 11 on the second workpiece 12, and use the stop block 63 to block and position to complete the installation of the first workpiece 11, so that the bolt holes 13 on the first workpiece 11 and the second workpiece 12 are aligned. The locking gun 92 moves to the bolt position 8 through the three-dimensional driving mechanism. The locking gun 92 extracts the locking bolt 91, and the three-dimensional driving mechanism drives the bolt to rotate to the position of the corresponding bolt hole 13 on the end face of the first workpiece 11, and locks the bolt in the corresponding bolt hole 13 to complete the bolt locking operation from this end face to the direction of the second workpiece 12.

[0066] When flipping is required, the horizontal drive module 96 and the vertical drive module 94 are used to drive the gripper 792 to move above the backing plate 72. The lifting mechanism 74 is used to drive the gripper 792 to move downward, and the bump 793 on the gripper 792 is aligned with the gripper hole 73. The opening and closing mechanism is used to drive the gripper 792 to move relatively, and the two grippers 792 clamp and fix the backing plate 72. Then, with the cooperation of the lifting mechanism 74, the horizontal drive module 96 and the vertical drive module 94, the backing plate 72 is placed on the end face of the first workpiece 11. The stopper motor 61 rotates to drive the stopper arm 62 to rotate onto the backing plate 72 and clamp the backing plate 72 to complete the fixation. The rotation motor 52 is started, and the rotation motor 52 drives the working plate 56 to rotate 180 degrees, so that the end face of the second workpiece 12 facing away from the first workpiece 11 is arranged upward. At the same time, the bolt hole 13 to be locked on the second workpiece 12 is exposed through the mounting through hole 58 on the working plate 56. The locking gun 92 repeats the above actions to tighten the locking bolt 91 into the corresponding bolt hole 13 on the end face of the second workpiece 12, thereby completing the bolt locking operation of the first workpiece 11 and the second workpiece 12.

[0067] After the operation is completed, the rotation motor 52 rotates in reverse, the stopper arm 62 rotates outward, and the backing plate tooling drives the backing plate 72 to be placed in the backing plate position. The staff takes out the assembled first workpiece 11 and second workpiece 12 to complete the operation.

[0068] In summary, for the bolt locking device of the present utility model, by providing a positioning groove 57 on the end face of the working plate 56 and an installation through hole 58 at the bottom of the positioning groove 57, the placement positions of the first workpiece 11 and the second workpiece 12 can be positioned through the positioning groove 57, so that the bolt holes 13 on the two are aligned. The installation through hole 58 can expose the bolt hole 13 at the lower end of the second workpiece 12. On the one hand, when screwing the bolt downward from the first workpiece 11, the bolt head can be prevented from touching the working plate 56, causing assembly failures. On the other hand, when it is necessary to flip and screw the bolt from the second workpiece 12 to the first workpiece 11, the bolt hole 13 on the end face of the second workpiece 12 facing away from the first workpiece 11 can be exposed, facilitating bolt locking.

[0069] The rotation mechanism 51 can be used to drive the first workpiece 11 and the second workpiece 12 to flip, meeting the requirement of bolt locking from different end faces, reducing the working intensity of the staff, and improving the operation efficiency and safety.

[0070] The stopper clamping mechanism 6 can be used to clamp the first workpiece 11 and the second workpiece 12 on the working plate 56. On the one hand, it can prevent shaking during the process of tightening the bolt, and on the other hand, it can prevent the workpiece from falling off after flipping.

[0071] With the locking device, the locking gun 92 can be driven by a three-dimensional drive mechanism and moved to the position of the locking bolt 91 to complete the extraction of the locking bolt 91. Then, it is moved to the position of the bolt hole 13 under the drive of the three-dimensional drive mechanism to complete the bolt locking, realizing automatic operation. On the one hand, the assembly efficiency is improved, and on the other hand, it can ensure that the locking bolt 91 is tightened in the corresponding bolt hole 13 with uniform and the same force, ensuring the product quality.

[0072] With this device, the workpiece can be flipped and the bolt can be locked efficiently, stably and precisely, ensuring the stability of bolt tightening, reducing the manual operation intensity, improving the production efficiency and product quality, and ensuring the operation safety.

[0073] Embodiment 2: This embodiment provides a different bolt locking device. Different from Embodiment 1, when meeting the actual use requirements, in this embodiment, the backing plate tooling may not be provided. At this time, the height of the stop arm is adapted to the height of the first workpiece. When flipping is required, the stop arm is used to directly stop and clamp the first workpiece and the second workpiece. At the same time, when locking the bolt from the end face of the first workpiece to the second workpiece, the stop arm can also be used to fix the first workpiece to prevent the first workpiece from moving during the process of tightening the bolt, ensuring the quality.

[0074] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.

[0075] In the description of the embodiments of the present application, it should be noted that if terms such as "upper", "lower", "horizontal", "inner", etc. are used to indicate the orientation or position relationship, it is based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the invention product is usually placed during use. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the present application. In addition, terms such as "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0076] In addition, if the term "horizontal" appears, it does not mean that the component is required to be absolutely horizontal, but it can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and it does not mean that the structure must be completely horizontal, but it can be slightly inclined.
