Description

Technical Field

[0001] This application relates to the field of electromagnetic contactor manufacturing technology, and in particular to a riveting device for connecting the electrode plate and the clamping leaf spring of an electromagnetic contactor. Background Technology

[0002] Electromagnetic contactors are commonly used electrical control devices in industrial automation and power systems. An electromagnetic contactor consists of a riveted structure of plates and clamping springs. Its operating principle is based on electromagnetic induction and magnetic force. By controlling the contact assembly between the contactor and the plates, it achieves switching control of the circuit.

[0003] In the manufacturing of the riveting structure of the electrode plate and the clamping spring, the relevant technology requires workers to manually rivet the electrode plate and the clamping spring together. This method is inefficient and makes it difficult to guarantee the riveting quality. Utility Model Content

[0004] To improve the riveting efficiency of the electromagnetic contactor's electrode plate and clamping spring, this application provides a riveting device for the electromagnetic contactor's electrode plate and clamping spring. The device involves passing the electromagnetic contactor's electrode plate and clamping spring through a first through slot and a second through slot, respectively. The clamping spring is then blocked by a stop block, while a stop block is lifted, compressing the clamping spring and increasing its elastic potential energy. The electromagnetic contactor's electrode plate extends between the stop block and the stop block. The stop block, under the action of the clamping spring's elastic potential energy, presses against the top of the electromagnetic contactor's electrode plate, vertically limiting its position. Finally, an external drive cylinder or linear motor drives a rivet through a riveting hole. The rivet passes sequentially through the electromagnetic contactor's electrode plate and clamping spring, contacting the lower riveting die and deforming, thus riveting the electromagnetic contactor's electrode plate and clamping spring together. This method improves both the riveting efficiency and the quality of the riveting process.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, this application provides a riveting device for connecting the electrode plate of an electromagnetic contactor to a clamping leaf spring, comprising:

[0030] The support base 1 has a first through groove 11 for accommodating the electrode plate of the electromagnetic contactor and a second through groove 12 for accommodating the clamping spring of the electromagnetic contactor on its side. The first through groove 11 and the second through groove 12 are connected. The top of the support base 1 has a riveting hole 13, which is connected to the first through groove 11.

[0031] The lower riveting mold 2 is connected to the support base 1 along the axis of the riveting hole 13, and the top of the lower riveting mold 2 is provided with a groove for accommodating rivets.

[0032] The stop block 3 is fixedly connected to one side of the support base 1, and the top wall of the stop block 3 protrudes from the bottom wall of the second through groove 12;

[0033] The plug 4 is connected to the top of the stop block 3 by a fixing bolt 5, and a clamping spring 51 is provided on the periphery of the fixing bolt 5. One end of the clamping spring 51 is in contact with the end of the fixing bolt 5, and the other end of the clamping spring 51 is in contact with the plug 4.

[0034] In some embodiments, the support base 1 may be made of cast iron, and the first through groove 11 and the second through groove 12 are both horizontally opened. The setting height of the first through groove 11 is greater than the setting height of the second through groove 12, that is, the bottom wall of the first through groove 11 is in contact with the top wall of the second through groove 12, and the cross sections of the first through groove 11 and the second through groove 12 are T-shaped. The first through groove 11 and the second through groove 12 are both arranged through the same side wall of the support base 1.

[0035] To facilitate the replacement of the lower riveting mold 2, a through circular hole is provided at the bottom of the support base 1, and the size of the circular hole is the same as that of the lower riveting mold 2. After the lower riveting mold 2 passes through the circular hole, it extends into the second through groove 12. At the same time, the circular hole and the riveting hole 13 are coaxially arranged.

[0036] This application provides a riveting device for an electromagnetic contactor electrode plate and a clamping spring. The device involves passing the electromagnetic contactor electrode plate and the clamping spring through a first through slot 11 and a second through slot 12, respectively. The clamping spring is then blocked by a stop block 3, while a stop block 4 is lifted, compressing the clamping spring 51 and increasing its elastic potential energy. The electromagnetic contactor electrode plate extends between the stop block 4 and the stop block 3. Then, under the action of the elastic potential energy of the clamping spring 51, the stop block 4 presses against the top of the electromagnetic contactor electrode plate, vertically limiting its position. Finally, an external driving cylinder or linear motor drives a rivet through a riveting hole 13. The rivet passes through the riveting hole 13 sequentially through the electromagnetic contactor electrode plate and the clamping spring, contacting the lower riveting mold 2 and deforming, thus riveting the electromagnetic contactor electrode plate and the clamping spring together. This method improves the riveting efficiency of the electromagnetic contactor electrode plate and the clamping spring while ensuring the riveting quality.

[0037] In some embodiments, in order to facilitate the limiting of the clamping leaf spring of the electromagnetic contactor, in the riveting device for the electromagnetic contactor electrode plate and the clamping leaf spring provided in this application, the side of the stop block 3 near the support base 1 is configured as an inclined surface for supporting the clamping leaf spring of the electromagnetic contactor.

[0038] The inclined surface can be implemented as a symmetrical inclined surface on both sides, thereby increasing the contact area between the clamping leaf spring of the electromagnetic contactor and the stop block 3, and improving the stability of limiting the clamping leaf spring.

[0039] In some embodiments, the top of the plug 4 is provided with an elongated hole 41, the height of the elongated hole 41 is less than the height of the plug 4, the long side of the elongated hole 41 is perpendicular to the axial direction of the fixing bolt 5, and the fixing bolt 5 passes through the elongated hole 41 and is threadedly connected to the stop block 3.

[0040] By opening an elongated hole 41 at the top of the plug 4, it is convenient to store the clamping spring 51 inside the elongated hole 41, thereby ensuring the reliable operation of the clamping spring 51 and improving the service life of the clamping spring 51.

[0041] Reference Figure 4 In some embodiments, the riveting device for connecting the electromagnetic contactor electrode plate and the clamping leaf spring provided in this application further includes:

[0042] The base 6 is fixedly connected to the support 1, and the cross-sectional dimension of the base 6 is larger than the end face dimension of the support 1.

[0043] By setting a base 6 at the bottom of the support base 1, the support base 1 is supported by the base 6 with a larger cross-sectional area, thereby greatly improving the stability of the support base 1 and reducing the probability of the support base 1 overturning during the riveting process.

[0044] For example, the base 6 and the support 1 are fixedly connected by welding.

[0045] In some embodiments, the base 6 has at least two mounting holes 61, and the opening direction of the mounting holes 61 is parallel to the opening direction of the riveting holes 13.

[0046] For example, the base 6 has two mounting holes 61.

[0047] Workers can fix the base 6 by inserting bolts into the mounting holes 61, thereby further reducing the probability of the support 1 overturning.

[0048] In some embodiments, the base 6 has a connecting hole, and a screw 21 is connected to the connecting hole. The screw 21 passes through the connecting hole and is threadedly connected to the lower riveting mold 2.

[0049] To ensure reliable fixing of the lower riveting mold 2, a screw 21 is passed through the connecting hole and threadedly connected to the lower riveting mold 2, so that the lower riveting mold 2 and the base 6 are integrated, thereby ensuring the support of the lower riveting mold 2 for the riveting process of the electromagnetic contactor plate and the clamping leaf spring.

[0050] In some embodiments, the riveting hole 13 is provided with a chamfer, and the cross-sectional area of ​​the riveting hole 13 gradually decreases toward the first through groove 11.

[0051] By setting a chamfer at the rivet hole 13, the chamfer can guide the rivet, which can greatly facilitate the rivet to pass through the rivet hole 13, thereby improving the efficiency of riveting the electromagnetic contactor plate and the clamping leaf spring.

[0052] This application provides a riveting device for an electromagnetic contactor electrode plate and a clamping spring. The device involves passing the electromagnetic contactor electrode plate and the clamping spring through a first through slot 11 and a second through slot 12, respectively. The clamping spring is then blocked by a stop block 3, while a stop block 4 is lifted, compressing the clamping spring 51 and increasing its elastic potential energy. The electromagnetic contactor electrode plate extends between the stop block 4 and the stop block 3. Then, under the action of the elastic potential energy of the clamping spring 51, the stop block 4 presses against the top of the electromagnetic contactor electrode plate, vertically limiting its position. Finally, an external driving cylinder or linear motor drives a rivet through a riveting hole 13. The rivet passes through the riveting hole 13 sequentially through the electromagnetic contactor electrode plate and the clamping spring, contacting the lower riveting mold 2 and deforming, thus riveting the electromagnetic contactor electrode plate and the clamping spring together. This method improves the riveting efficiency of the electromagnetic contactor electrode plate and the clamping spring while ensuring the riveting quality.
