Specific embodiments

[0023] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0024] As Figures 1 to 5 shown, this embodiment proposes a connector positioning tooling, which includes a side plate A1, a side plate B2, an outer alignment plate 3, an inner alignment plate 4 and a side plate positioning component 5. The side plate positioning component 5 is used to position the side plate A1 and the side plate B2. Alignment holes 6 are opened at both ends of the outer alignment plate 3 and the inner alignment plate 4, and a plurality of spot welding reserved holes 7 are opened at both ends of each alignment hole 6. The side plate positioning component 5 includes a mounting cylinder 8, a limiting cylinder 9 and a positioning cylinder 10. A limiting cylinder 9 is arranged on one side of the mounting cylinder 8, and a positioning cylinder 10 is arranged at the end of the limiting cylinder 9 away from the mounting cylinder 8;

[0025] Specifically, the mounting cylinder 8, the limiting cylinder 9 and the positioning cylinder 10 are integrally formed, and the diameters of the mounting cylinder 8, the limiting cylinder 9 and the positioning cylinder 10 decrease in sequence. By producing the mounting cylinder 8, the limiting cylinder 9 and the positioning cylinder 10 in an integrally formed manner, the strength between the mounting cylinder 8, the limiting cylinder 9 and the positioning cylinder 10 can be ensured;

[0026] The side plate positioning assembly 5 further includes a central shaft rod 11, a threaded section 12, a displacement frame 13 and a stop arc plate 14. The central shaft rod 11 is rotatably connected inside the mounting cylinder 8. Threaded sections 12 are provided at both ends on the outer side of the central shaft rod 11, and the thread directions of the two threaded sections 12 are opposite. Displacement frames 13 are threadedly connected to the outer sides of the two threaded sections 12. One end of the displacement frame 13 is fixedly connected to the stop arc plate 14. Two storage grooves are provided on the outer side of the limiting cylinder 9, and the two stop arc plates 14 are respectively assembled inside the two storage grooves;

[0027] Specifically, a linear slide bar is fixedly connected inside the mounting cylinder 8, and both displacement frames 13 are slidably connected to the linear slide bar. By means of the setting of the linear slide bar, the displacement of the displacement frame 13 can be effectively guided to prevent the displacement frame 13 from rotating uncontrollably;

[0028] The side plate positioning assembly 5 further includes a positioning seat 15, a transmission shaft rod 16, a transmission bevel gear 17, a transmission screw rod 18 and a displacement push plate 19. The positioning seat 15 is fixedly connected to the inner wall of the limiting cylinder 9. The transmission screw rod 18 is rotatably connected to the bottom end of the positioning seat 15. The transmission shaft rod 16 is also rotatably connected inside the mounting cylinder 8. Transmission bevel gears 17 are fixedly connected to the bottom end of the transmission shaft rod 16 and the end of the transmission screw rod 18 close to the transmission shaft rod 16, and the two transmission bevel gears 17 are meshed. The displacement push plate 19 is threadedly connected to the outer side of the transmission screw rod 18. Limiting plates 20 are fixedly connected to both ends inside the positioning cylinder 10. A displacement slide bar 21 is slidably connected to the middle of the limiting plate 20. One end of the displacement slide bar 21 is fixedly connected to a force receiving plate 22. A spiral spring 23 is fixedly connected between the force receiving plate 22 and the limiting plate 20. The end of the displacement slide bar 21 away from the force receiving plate 22 is fixedly connected to a positioning arc plate 24. Storage grooves are provided on both sides of the positioning cylinder 10, and the two positioning arc plates 24 are respectively located inside the two storage grooves. One end of the displacement push plate 19 close to the force receiving plate 22 is fixedly connected to a pressing plate 25;

[0029] Furthermore, a stabilizing seat is also fixedly connected to the inner wall of the limiting cylinder 9, and the end of the transmission screw rod 18 close to the stabilizing seat is also rotatably connected to the stabilizing seat. By means of the setting of the stabilizing seat, the transmission screw rod 18 can be supported to prevent the transmission screw rod 18 from shaking;

[0030] Preferably, a limiting hole is formed at the bottom end of the stability maintaining seat, and the displacement push plate 19 is also slidably connected inside the limiting hole. By means of the arrangement of the limiting hole, the displacement of the displacement push plate 19 can be effectively guided to prevent the displacement push plate 19 from rotating along with the transmission screw rod 18;

[0031] Wherein, a guiding plate is obliquely and fixedly connected to one end of the force receiving plate 22 close to the pressing plate 25. Ramps adapted to the inclined surfaces of the guiding plate are formed at both ends of the pressing plate 25, and the ramps are in fit with the inclined surfaces of the guiding plate. By means of the arrangement of the guiding plate and the ramps, when the pressing plate 25 linearly displaces, the guiding plate can be pushed, causing the displacement sliding rod 21 to displace under the limitation of the limiting plate 20.

[0032] A specific application of the above embodiment is that a laser cutting machine is used to process the assembly positions of the outer alignment plate 3 and the inner alignment plate 4 at the side plate A1 and the side plate B2. When assembling the outer alignment plate 3 and the inner alignment plate 4, the connector shaft is used as a reference to position the outer alignment plate 3 and the inner alignment plate 4, and the dimension is more accurate. The error depends on the error of the laser cutting machine cutting the material and is less than 0.5 mm;

[0033] Moreover, when lofting and scribing on the side plate A1 and the side plate B2, first, the side plate B2 is sleeved on the outside of the limiting cylinder 9. Since the diameter of the carrying cylinder 8 is larger than that of the limiting cylinder 9, the side plate B2 can be received by the carrying cylinder 8, and then the side plate A1 is sleeved on the outside of the positioning cylinder 10. Since the diameter of the positioning cylinder 10 is smaller than that of the limiting cylinder 9, the side plate A1 can be received by the limiting cylinder 9, thus completing the assembly between the side plate A1 and the side plate B2. Subsequently, the lofting line is drawn on the side plate A1 and the side plate B2 according to the outer contour line in the drawing. The side plate A1 is assembled to the side plate B2, and then the center lines of the outer alignment plate 3 and the inner alignment plate 4 are drawn according to the outer contour edges of the side plate A1 and the side plate B2 for assembly;

[0034] Moreover, when the diameter of the limiting cylinder 9 is not suitable for the side plate B2, the central shaft rod 11 can be rotated. With the arrangement of the two threaded sections 12 with opposite thread directions, the two displacement frames 13 can be driven to displace towards each other until the two transmission shaft rods 16 contact the side plate B2, so that the side plate B2 can be supported by the stop arc plate 14 to prevent uncontrollable displacement of the side plate B2, thereby realizing the positioning of side plates B2 of different models;

[0035] When the diameter of the positioning cylinder 10 does not match the side plate A1, rotate the transmission shaft rod 16. With the connection between the two transmission bevel gears 17, it can drive the transmission screw rod 18 to rotate. And with the connection between the transmission screw rod 18 and the displacement push plate 19, it can drive the displacement push plate 19 to displace along the transmission screw rod 18. Then, through the extrusion plate 25 to push the force-bearing plate 22, it can cause the displacement sliding rod 21 to slide under the support of the limiting plate 20 until the positioning arc plate 24 contacts the side plate A1. In this way, the support for side plates A1 of different models can be completed, greatly improving the overall applicability. And when the displacement sliding rod 21 displaces, it can squeeze the spiral spring 23 through the force-bearing plate 22. After the extrusion plate 25 moves away from the force-bearing plate 22, the resilience of the spiral spring 23 can be used to drive the positioning arc plate 24 to reset;

[0036] The alignment hole 6 is prefabricated in advance by a laser cutting machine, and the spot welding reserved hole 7 is opened in the alignment hole 6, which can facilitate subsequent welding. When the spot welding reserved hole 7 is assembled, it is made concentric with the same axis as the alignment hole 6 to ensure the concentricity when the outer alignment plate 3 and the inner alignment plate 4 are assembled.

[0037] In summary, the present utility model at least has the following beneficial effects:

[0038] 1. Reduce the time for workers to align and position the outer alignment plate 3 and the inner alignment plate 4 of the coupler and the side plates A1 and B2. It can complete one product in 30% of the original time, greatly improving the overall production efficiency.

[0039] 2. Use the side plate positioning assembly 5 to assemble the side plates A1, B2, the outer alignment plate 3 and the inner alignment plate 4 of the coupler, so that the concentricity of the outer contours of the outer alignment plate 3 and the inner alignment plate 4 can be ensured within the tolerance range.

[0040] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
