[0001] The utility model relates to the technical field of jigs, and in particular to a jig circulation structure. Background Art
[0002] Jigs are often used in the field of automation. Jigs are used to load materials for operations. For example, jigs are used to load materials for processing, assembly, shaping or testing and other automated operations. In order to improve the degree of automation, the jig needs to operate in a cycle, that is, the jig loaded with materials needs to flow back to the front end after completing the corresponding workstation to receive the materials to be operated again and load the materials to be operated to operate at the corresponding workstation again. The existing jig circulation structure has the disadvantages of complex structure, large structure volume and poor circulation accuracy. Utility Model Content
[0003] The utility model aims to provide a jig circulation structure, which mainly solves the technical problems of the existing jig circulation structure, which is complex in structure, large in volume and poor in circulation accuracy.
[0004] To achieve this purpose, the utility model adopts the following technical solutions:
[0005] A jig circulation structure comprises a plurality of jigs, wherein the jigs comprise a connected main body and a towing hook, wherein a hook groove is arranged at one end of the main body away from the towing hook, and both ends of the hook groove penetrate the jig so that both ends of the hook groove have openings, and the hook groove on each jig is used for the towing hook on another jig to be embedded, so that when the jig moves, the towing hook can apply a pulling force to the groove wall of the hook groove to pull the other jig to follow the movement, and one of the openings on each jig is used for the towing hook on another jig to enter the hook groove, and the other opening on each jig is used for the towing hook on another jig to leave the hook groove.
[0006] In one of the technical solutions, the towing hook includes a connected rotating shaft and a roller, the rotating shaft is connected to the main body and extends into the hook groove, the roller is embedded in the hook groove, and the roller can rotate freely relative to the main body with the central axis of the rotating shaft as the rotation axis, and the two openings on the fixture are larger than the outer diameter of the roller.
[0007] In one of the technical solutions, the rotating shaft is fixedly connected to the main body, and the roller includes an inner ring and an outer ring which are rotatably connected, and the inner ring is sleeved on the outer wall of the rotating shaft and fixedly connected to the rotating shaft.
[0008] In one of the technical solutions, a secondary positioning groove is provided on the jig, and the secondary positioning groove is used to allow the jig to be positioned at a preset position.
[0009] In one of the technical solutions, a secondary positioning groove is provided at both ends of the hook groove.
[0010] In one of the technical solutions, the notch of the hook groove is open upward, and the towing hook on the jig is first bent upward and then extended horizontally and finally bent downward and finally extended into the hook groove on the other jig.
[0011] In one of the technical solutions, when a plurality of the jigs are connected and move along a first direction, the towing hook and the hook groove are arranged at different ends of the main body in the first direction, and the hook groove penetrates the main body along a second direction, and the second direction is perpendicular to the first direction.
[0012] Compared with the prior art, the fixture circulation structure provided by the utility model has at least the following beneficial effects:
[0013] During operation, multiple jigs are connected in sequence by embedding the towing hooks into the hook grooves. When one of the jigs is driven to move, multiple jigs can be moved together. Moreover, when multiple jigs are moving, the relative position accuracy between the multiple jigs is high due to the cooperation between the towing hooks and the hook grooves. When the front jig needs to be separated, the front jig can be driven to move horizontally, so that the towing hook on the front jig is separated from the hook groove on the rear jig from the opening, and the separated jig and another row of jigs are docked with each other. During docking, the separated jig can enter the hook groove on the jig in another row through the towing hook along the opening on one row of jigs and dock with the jig in another row. The separated jig can also be docked with the jig in another row by moving to a predetermined position so that its hook groove is embedded by the towing hook on the jig in another row.
[0014] In summary, the fixture using the present technical solution can make the fixture perform a circular cycle, and each row of fixtures can be interlocked in sequence, which can greatly reduce the volume of the equipment, and the relative position accuracy between the fixtures is higher. It is extremely simple to separate or dock the fixtures with each other, and has the advantages of simple structure and high cycle accuracy. In addition, the fixture of this solution also has the advantage of strong load capacity. When the fixture carries a heavier load, the fixtures can still maintain high stability, reliability and cycle accuracy when they are separated or docked with each other.

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0025] Please also read Figure 1 and Figure 2 This embodiment provides a fixture circulation structure, which includes a plurality of fixtures 10 connected in sequence. Figure 1The example mainly takes two jigs 10 connected. The jig 10 specifically includes a main body 101 and a towing hook 102 connected to each other. The main body 101 is used to connect with the linear guide rail to improve the motion accuracy of the jig 10 when it moves in a straight line. The main body 101 is provided with a hook groove 103 at one end away from the towing hook 102. Both ends of the hook groove 103 penetrate the main body 101, so that both ends of the hook groove 103 have openings 104. The notch of the hook groove 103 is open upward, and the towing hook 102 is first bent upward and then extended horizontally and finally bent downward, so that the towing hook 102 on the jig 10 can be embedded downward into the hook groove 103 of another jig 10. When multiple jigs 10 are connected in sequence by their respective towing hooks 102 being embedded in the corresponding hook grooves 103, only one of the jigs 10 needs to be driven to move, and multiple jigs 10 can be moved together at the same time.
[0026] More specifically, one of the openings 104 on the jig 10 is used to allow the tow hook 102 on another jig 10 to enter the corresponding hook groove 103, so that the two jigs are connected to each other; the other opening 104 on the jig 10 is used to allow the tow hook 102 on another connected jig 10 to leave the corresponding hook groove 103, so that the two jigs 10 are separated from each other. Specifically, when the front jig 10 needs to be separated, the front jig 10 can be driven to move laterally, so that the towing hook 102 on the front jig 10 is disengaged from the hook groove 103 on the rear jig from the opening 104, and the separated jig 10 and another row of jigs 10 are docked with each other. During docking, the separated jig 10 can enter the hook groove 103 on the other row of jigs 10 along the opening 104 on one row of jigs 10 through the towing hook 102 and dock with the other row of jigs 10. The separated jig 10 can also be docked with the other row of jigs 10 by moving to a predetermined position so that its hook groove 103 is embedded by the towing hook 102 on the other row of jigs 10.
[0027] In this embodiment, when multiple jigs 10 are connected and move along a first direction (i.e., the X-axis direction), the towing hook 102 and the hook groove 103 are respectively arranged at different ends of the main body 101 along the X-axis direction, and the hook groove 103 preferably penetrates the main body 101 along a second direction (i.e., the Y-axis direction), and the second direction is perpendicular to the first direction, so that the jig 10 can circulate in a regular rectangular circular path.
[0028] In this embodiment, the towing hook 102 specifically includes a connected rotating shaft 1021 and a roller 1022, the rotating shaft 1021 is fixed on the main body 101 and is used to extend into the hook groove 103 of a corresponding fixture 10, and the roller 1022 is preferably a bearing, that is, the roller 1022 includes an inner ring and an outer ring that are rotatably connected, the inner ring of the roller 1022 is sleeved on the rotating shaft 1021 and fixed coaxially with the rotating shaft 1021, and the roller 1022 is used to be embedded in the hook groove 103 of a corresponding fixture 10, and the outer ring of the roller 1022 can pull the rear fixture 10 to follow the movement by applying a pulling force to the groove wall of the hook groove 103. By providing a rotatable roller 1022, the friction between the towing hook 102 and the groove wall of the hook groove 103 can be greatly reduced, thereby ensuring the circulation accuracy of the fixture 10 during the circulation process. In addition, the openings 104 at both ends of the hook groove 103 are larger than the outer diameter of the roller 1022 , so that the roller 1022 can enter the hook groove 103 from the openings 104 , or the roller 1022 can escape from the hook groove 103 from the openings 104 .
[0029] In other embodiments, the above-mentioned roller 1022 can be designed as an integral part with the rotating shaft 1021, and then a bearing is installed between the rotating shaft 1021 and the main body 101. In this case, the function of the roller 1022 being able to rotate freely relative to the main body 101 can also be achieved, that is, the friction between the towing hook 102 and the groove wall of the hook groove 103 can also be greatly reduced.
[0030] In this embodiment, a secondary positioning groove 105 is provided on the main body 101 of the fixture 10. By providing the secondary positioning groove 105, the fixture 10 can be accurately positioned at a specified position, so that the external equipment can more accurately operate the material on the fixture 10. Preferably, one of the above-mentioned secondary positioning grooves 105 is provided on both ends of the hook groove 103.
[0031] In summary, the jig 10 of the present technical solution can make the jig 10 perform a circular cycle, and each row of jigs 10 can be interlocked in sequence, which can greatly reduce the volume of the equipment, and the relative position accuracy between the jigs 10 is high. It is extremely simple to separate or dock the jigs 10 with each other, and has the advantages of simple structure and high cycle accuracy. In addition, the jig 10 of the present solution also has the advantage of strong load capacity. When the jig 10 carries a heavier load, the jigs 10 and the jigs 10 can still maintain high stability, reliability and cycle accuracy when they are separated or docked with each other.
[0032] The above are only preferred embodiments of the present invention, and only specifically describe the technical principles of the present invention. These descriptions are only for the purpose of explaining the principles of the present invention, and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanation here, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention, and other specific implementation methods of the present invention that can be associated with by technicians in this field without creative labor, should be included in the scope of protection of the present invention.
