[0035] One embodiment of the present application provides a production device, which includes a conveyor and a jig assembly. The jig assembly is arranged on the conveyor, and the jig assembly is used to carry the workpiece. The conveyor can drive the jig assembly to move to different stations so that the workpiece completes each process. For example, the production device can be an automatic assembly device, and the workpiece can be an insulator of an electrical connector. The workpiece is arranged on the jig assembly, and the conveyor can carry the workpiece to the riveting station, and the pin is pressed into the insulator by riveting to achieve automatic assembly. Of course, the production device can also be other devices, such as a detection device, etc., which will not be repeated here.

[0036] In one embodiment, the conveying member may be a turntable, a conveyor belt, or the like.

[0037] In one embodiment, the jig assembly includes a tooling jig 10, which can be used to carry workpieces of different shapes and sizes and has a high degree of versatility. For example, the tooling jig 10 can be used to carry insulators of different shapes and sizes, facilitating the assembly of various electrical connectors.

[0038] Refer to FIG. 1 , which shows an exploded schematic diagram of a jig 10 in an embodiment of the present application. The jig 10 includes a base 100 and a receiving structure 200, and the base 100 is provided with an insertion hole 101. The receiving structure 200 includes an insertion section 201 and a connecting section 202, the insertion section 201 is plugged into the insertion hole 101, and the receiving structure 200 is detachably connected to the hole wall of the insertion hole 101. The shape of the connecting section 202 is adapted to the workpiece for plugging with the workpiece.

[0039] In the above-mentioned jig 10, the shape of the connecting section 202 of the accommodating structure 200 is adapted to the workpiece, so it can stably carry the workpiece. The insertion section 201 of the accommodating structure 200 is plugged into the insertion hole 101, so that the accommodating structure 200 is connected to the base 100. Since the accommodating structure 200 and the hole wall of the insertion hole 101 are detachably connected, the accommodating structure 200 can be separated from the base 100 by disassembling it, so that a different accommodating structure 200 can be replaced. Compared with replacing the jig 10 as a whole, the cost of replacing the accommodating structure 200 is lower and it is easy to operate.

[0040] As shown in Figures 4 to 13, the present application also provides a jig assembly, which includes a tooling fixture 10 as described in each embodiment. The tooling fixture 10 may include a base 100 and a plurality of accommodating structures 200. The shape and / or size of the connecting section 202 of each accommodating structure 200 are different to adapt to different workpieces. The insertion section 201 of each accommodating structure 200 can be used to be plugged into the insertion hole 101 and detachably connected to the hole wall of the insertion hole 101 for disassembly and replacement. Thus, by replacing different accommodating structures 200, the jig assembly can be adapted to carry a variety of different workpieces, thereby improving the versatility of the jig assembly. In addition, the jig assembly is arranged on the conveying member. Compared with replacing the entire tooling fixture 10, the cost of replacing only the accommodating structure 200 is lower, and it is also convenient to operate and replace.

[0041] Please refer to Figures 2 to 4. In one embodiment, the accommodating structure 200 can be detachably connected to the base 100 in the form of a threaded connection. That is, the accommodating structure 200 includes a accommodating tube 210 and a fastener (not shown in the figure, the same below), and the fastener passes through the accommodating tube 210. The accommodating tube 210 includes an insertion section 201 and a connecting section 202. One end of the fastener abuts against the side of the accommodating tube 210 away from the base 100, and the other end is threadedly connected to the hole wall of the insertion hole 101. In this way, the accommodating tube 210 can be stably pressed on the base 100 by the fastener abutting against the side of the accommodating tube 210 away from the base 100, thereby improving the position stability of the accommodating structure 200. The accommodating structure 200 and the base 100 are detachably connected by threaded connection, which is convenient for processing and manufacturing.

[0042] In one embodiment, the fastener may be a threaded connection member such as a screw or a bolt.

[0043] In another embodiment, the insertion section 201 may also be detachably connected to the insertion hole 101 by a rotating snap-fit ​​connection.

[0044] Please refer to FIG. 4 . In one embodiment, a through hole 220 and a receiving hole 230 are provided in the receiving tube 210 . The diameters of the through hole 220 and the receiving hole 230 are different, and a step 240 is formed at the junction. One end of the fastener abuts against the step 240, and the other end passes through the through hole 220 and is connected to the hole wall of the insertion hole 101 . The receiving hole 230 is used for inserting a workpiece. In this way, the fastener can conveniently fix the receiving tube 210 and the base 100 together.

[0045] Please refer to Figures 3 and 4. In one embodiment, a positioning key 250 is protruded from the inner wall of the receiving hole 230. The positioning key 250 is used to cooperate with the workpiece for positioning. In this way, the workpiece can be positioned by the positioning key 250, thereby improving the position stability of the workpiece, reducing the probability of circumferential misalignment of the workpiece due to factors such as vibration during the conveying process, and facilitating processing and production.

[0046] Furthermore, the workpiece is provided with a matching groove (not shown in the figure, the same below), and when the workpiece is plugged into the connecting section 202, the matching groove is plugged into and matched with the positioning key 250 to achieve positioning.

[0047] Of course, due to the different shapes and sizes of workpieces, the positioning key 250 is not limited to being disposed on the inner wall of the receiving hole 230. As shown in Figures 5 and 6, in one embodiment, the positioning key 250 can be disposed on the end surface of the connecting section 202 for positioning with the workpiece.

[0048] Please refer to Figures 1 and 9. In one embodiment, the insertion hole 101 includes a coaxially arranged connecting hole 111 and a positioning hole 121, and the positioning hole 121 is closer to the connecting section 202 than the connecting hole 111. The hole wall of the connecting hole 111 is detachably connected to the accommodating structure 200. The positioning hole 121 and the insertion section 201 are limited to limit the circumferential rotation of the accommodating structure 200. In this way, the position stability of the accommodating structure 200 after being inserted into the base 100 can be improved. The circumferential rotation refers to the rotation of the accommodating structure 200 in the direction around its circumference.

[0049] Furthermore, the insertion section 201 may be inserted only into the positioning hole 121 , and one end of the fastener extends out of the insertion section 201 to extend into the connecting hole 111 and connect with the hole wall of the connecting hole 111 .

[0050] Regarding the limiting cooperation between the positioning hole 121 and the insertion section 201, for example, a limiting groove (not shown in the figure, the same below) is provided in the axial direction of the positioning hole 121, and a limiting block (not shown in the figure, the same below) is provided on the outer periphery of the insertion section 201, and the limiting block is penetrated in the limiting groove. The limiting block abuts against the groove wall of the limiting groove, so the circumferential rotation of the accommodating structure 200 can be limited. Of course, the same applies when the positions of the limiting block and the limiting groove are interchanged, so it will not be repeated.

[0051] Please refer to FIG. 4 and FIG. 7 , in another embodiment, a first plane 270 may be provided at one of the outer circumferential walls of the insertion section 201, and a second plane 122 may be provided at the inner circumferential wall of the positioning hole 121. After the insertion section 201 is plugged into the positioning hole 121, the first plane 270 fits with the second plane 122. In this way, the first plane 270 and the second plane 122 are in surface contact, so that the circumferential rotation of the accommodating structure 200 can also be restricted.

[0052] In one embodiment, there may be two first planes 270, and the two first planes 270 are arranged in parallel. There may also be two second planes 122, and the two second planes 122 are arranged in parallel. Of course, there may be other numbers of first planes 270 and second planes 122, which will not be described in detail here.

[0053] Please refer to FIG. 1 again. In one embodiment, the base 100 includes a base 110 and a positioning plate 120. The positioning plate 120 is disposed on the base 110, the connecting channel 111 is opened on the base 110, and the positioning channel 121 is opened on the positioning plate 120. The hole wall of the connecting channel 111 is detachably connected to the fastener, and the positioning channel 121 is limitedly matched with the insertion section 201 to limit the circumferential rotation of the accommodating structure 200. It is easy to understand that since the positioning channel 121 is used to position the insertion section 201, and the connecting channel 111 is matched with the fastener to achieve detachable connection, the two are different in the matching mode with the accommodating structure 200, and there are also differences in structure. Therefore, compared with directly opening the positioning channel 121 and the connecting channel 111 on the base 110, in this embodiment, the positioning channel 121 is opened on the positioning plate 120, and the connecting channel 111 is opened on the base 100, which reduces the difficulty of processing.

[0054] Of course, in one embodiment, the connecting hole 111 and the positioning hole 121 may be directly opened on the base 110 , and in this case, the base 100 may not include the positioning plate 120 .

[0055] In one embodiment, the positioning plate 120 may be fixed to the base 110 by threaded fasteners.

[0056] In one embodiment, one of the base 110 and the positioning plate 120 is provided with a positioning pin (not shown in the figure, the same below), and the other is provided with a matching hole (not shown in the figure, the same below), and a plurality of positioning pins are respectively positioned and matched with a plurality of matching holes, so that the positioning channel 121 and the connecting channel 111 are coaxially aligned. In this way, by positioning and matching a plurality of positioning pins and a plurality of matching holes respectively, the positioning plate 120 can be accurately installed on the base 110, and the positioning channel 121 and the connecting channel 111 can be coaxially arranged.

[0057] In one embodiment, the workpiece is not limited to being inserted into the receiving hole 230. The workpiece can also be sleeved outside the connecting section 202, that is, in this case, the connecting section 202 is inserted into the workpiece.

[0058] As shown in FIGS. 8 to 13 , in one embodiment, the connecting section 202 is used to penetrate into the workpiece, and the connecting section 202 is provided with a positioning groove 260, and the positioning groove 260 is used to cooperate with the workpiece in positioning. It is understandable that when the connecting section 202 is penetrated into the workpiece, the positioning key 250 provided in the connecting section 202 cannot position the workpiece, so the positioning groove 260 can be provided on the connecting section 202 to cooperate with the workpiece in positioning. For example, a stop block is protruded from the inner peripheral wall of the workpiece, and the stop block cooperates with the positioning groove 260 to achieve positioning.

[0059] Of course, the positioning key 250 may also be disposed on the outer periphery of the connecting section 202 to cooperate with the workpiece in positioning.

[0060] It is easy to understand that even if the workpiece is sleeved outside the connecting section 202, the connecting section 202 can still be provided with a receiving hole 230. Still taking the workpiece as an insulator as an example, the receiving hole 230 can be used to accommodate the pin inserted into the insulator. In short, even if the workpiece is sleeved outside the connecting section 202, the connecting section 202 is set to be a hollow structure that can avoid the inside of the workpiece, which is convenient for the installation of the workpiece.

[0061] As shown in FIG. 10 and FIG. 11 , in one embodiment, the number of the limiting grooves may be 2, 3, etc.

[0062] It needs to be explained again that, since each accommodating structure 200 is used to adapt to and plug in different workpieces, the connecting section 202 of the accommodating structure 200 can have different shapes and sizes, but since the insertion section 201 is used to connect with the base 100, the insertion section 201 of each accommodating structure 200 can have completely the same or similar structure to facilitate adaptation to the same insertion hole 101.

[0063] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
