Description

Technical Field

[0001] The utility model belongs to the technical field of riveting, and in particular relates to a riveting device for a positioning pin of a short-circuit handle seat. Background Art

[0002] An ignition circuit box is used for a certain anti-aircraft missile. The circuit box body is installed on the inner side of the front ring of the engine by screws. A conversion circuit is provided inside the circuit box, which is respectively connected to the ignition socket and the missile ignition control circuit to control the ignition of the missile. The ignition socket realizes the short circuit of the missile squib through an external short circuit handle. Whether the short circuit handle is rotated or not ensures whether the short circuit protection of the missile is effective when it is on the ground. The short circuit protection can be released by unscrewing the short circuit handle before the missile takes off.

[0003] In the early product design process, the ignition socket includes a rotary switch and a handle seat, and the handle seat includes a threaded hollow base and multiple positioning pins set on the side wall of the hollow base. The existing assembly method is to use interference fit between the positioning pin and the base to ensure that the positioning pin does not fall off when subjected to a force of at least 20N in the axial direction. However, due to the thin-walled structure of the base, it is difficult to achieve the assembly between the positioning pin and the base. After some products have undergone various environmental tests, the handle is plugged in and out many times, which will cause the positioning pin to loosen and eventually fall off, causing the short-circuit handle and the ignition socket to separate, affecting use.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-2The utility model provides the following technical solutions: a riveting device for a short-circuit handle seat locating pin, comprising a riveting platform 3, a step 10 and a step 2 11 are respectively provided at the bottom and the top of one side of the riveting platform 3, a positioning piece 5 is provided between the step 10 and the step 2 11, a positioning piece 2 is provided below the positioning piece 5, a limiting piece 1 for embedding the positioning piece 2 2 is placed on one side of the step 10, the positioning piece 1 5 and the positioning piece 2 2 are matched and fixed with a handle seat 6, a rivet groove 8 is provided on the top of the positioning piece 5, a positioning hole 9 corresponding to the rivet groove 8 is provided on the step 2 11, and a rivet cone 4 is inserted in the positioning hole 9.

[0018] Specifically, the cross-section of the positioning member 5 is fan-shaped, the top outer wall of which is in contact with the inner wall of the handle seat 6, and the bottom is flat. The rivet groove 8 is located in the middle of the top surface of the positioning member 5. A mounting hole for accommodating a locating pin is provided in the rivet groove 8. The mounting hole and the positioning hole 9 are concentrically arranged to facilitate the rivet cone 4 to quickly rivet the locating pin and avoid the phenomenon of crooked riveting.

[0019] Specifically, the top of the positioning member 2 is in contact with the bottom of the positioning member 1 5, the outer wall of the bottom has a certain curvature, and it is in contact with the inner wall of the handle seat 6. The handle seat 6 is first placed on the positioning member 1 5, and then the positioning member 2 2 is simply inserted into the inner wall of the handle seat 6 and adapted to the positioning member 1 5, so that the handle seat 6 can be positioned and connected.

[0020] Specifically, the width of step 10 is the same as the width of positioning member 15 and handle seat 6, so that when handle seat 6 is placed on positioning member 15, its end is flush with step 10 and the end of positioning member 15, so that limit member 1 can limit the end of handle seat 6 to prevent handle seat 6 from deviating outwards due to vibration or other external factors during riveting. The width of step 2 11 is greater than the width of step 10, ensuring that sufficient space is provided for the operation of riveting cone 4. The operator can more conveniently insert riveting cone 4 into positioning hole 9 and perform riveting operation. Since step 2 11 is wider, it can prevent riveting cone 4 from colliding with other parts of riveting platform 3 during operation to a certain extent, thereby avoiding possible equipment damage or operation error.

[0021] Specifically, a positioning groove 7 adapted to the positioning member 2 is provided on the top of the limiting member 1, and the top side wall of the limiting member 1 limits the end of the handle seat 6. The limiting member 1 can limit the end of the handle seat 6 to prevent the handle seat 6 from deviating outward due to vibration or other external factors during riveting.

[0022] Specifically, the materials of the limiter 1, the positioning member 2 and the riveting platform 3 are all T10A, and are all heat-treated. The selection of T10A material and heat treatment improves the strength and wear resistance of the device and extends its service life.

[0023] Working principle and use process of the utility model: The riveting device for the positioning pin of the short-circuit handle seat described in the utility model, when riveting is required, the positioning pin is placed in the riveting groove 8, and then the handle seat 6 is placed on the positioning piece 1 5, and at the same time, the positioning pin is inserted from the inside into the reserved riveting hole on the thin wall of the handle seat, and then the positioning piece 2 2 is inserted into the inner wall of the handle seat 6, and it is adapted to the positioning piece 1 5, and at the same time, the limiting piece 1 is embedded under the positioning piece 2, and the side wall of the limiting piece 1 is attached to the end of the handle seat 6 The end of the handle seat 6 is limited, and then the rivet cone 4 is inserted into the positioning hole 9 for riveting. After the riveting is completed, the limiter 1 and the positioning member 2 are disassembled respectively, and then the above steps are repeated to continue riveting until it is completed. It should be noted that since the cross-section of the positioning member 5 is fan-shaped and a cavity is left at the edge, the positioning pin on the riveted handle seat 6 will not be interfered by the side wall of the positioning member 5, and will not affect the subsequent riveting, and multiple riveting are performed with the same torque for constant pressure riveting.
