Description

Technical Field

[0001] This utility model relates to a riveting fixture for components used in the production of electricity meters. Background Technology

[0002] Electricity meters contain current transformers, which require copper posts for electrical connection to the terminals. In current technology, the connection between the copper posts and the current transformer is generally achieved through wires, which is relatively convenient. However, some electricity meters require a direct, rigid connection between the metal terminals of the current transformer and the copper posts, necessitating riveting. This connection method is more cumbersome. The metal terminals of the current transformer extend to both sides and are riveted to the copper posts, requiring specialized riveting fixtures for the process. Summary of the Invention

[0003] In order to overcome the above-mentioned shortcomings in the prior art, this utility model provides a riveting tool specifically used for riveting current transformer components in electricity meters.

[0004] This utility model is achieved through the following technical solution:

The outer side of the slot is open, and a slider of the same length as the assembly base is slidably provided on the outer side of the slot opening. A cam block is rotatably provided on the outer side of the slider, and the cam block rotates to push the slider to slide inward toward the slot or release the slider.

[0006] Preferably, a slide rod is fixed inside the slider, the slide rod is slidably inserted into the component base, and a spring is provided between the slide rod and the component base.

[0007] Preferably, multiple sets of pressing mechanism seats are provided on the inner side of the column groove. The pressing mechanism seats are provided with pressing mechanisms. The pressing mechanism includes a pressing handle and a handle that are movably connected to each other. One end of the pressing handle is provided with a pressing handle connecting end and the other end is provided with a pressing handle pressing end. One end of the handle is provided with a handle connecting end and the other end is provided with a handle pressing end. The handle is also provided with a handle hinge end near the handle connecting end. The upper part of the pressing handle connecting end is rotatably connected to the handle connecting end, and the lower part of the pressing handle connecting end is rotatably connected to the pressing mechanism seat. The handle hinge end is rotatably connected to the pressing mechanism seat through a connecting rod. The pressing handle pressing end can be pressed onto the current transformer assembly.

[0008] Preferably, the pressing mechanism seat is provided with an arc-shaped groove, the pressing handle connecting end and the handle hinge end are respectively connected to the two shoulders of the arc-shaped groove, and the outside of the handle is also provided with an arc-shaped protrusion that slides into or out of the arc-shaped groove as the handle rotates.

[0009] Preferably, the shape of the groove matches the copper column of the current transformer assembly.

This utility model has a reasonable structure, is easy to operate, and facilitates riveting by riveting equipment. Attached Figure Description

[0011] Figure 1 This is a structural schematic diagram of the utility model.

[0012] Figure 2 This is a partial structural schematic diagram of the present invention. Detailed Implementation

[0013] The utility model will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0014] like Figure 1 , 2 As shown, a riveting fixture for an electric meter transformer assembly includes a fixture base 1, on which an assembly base 2 is mounted. Multiple sets of transformer assemblies 5 are fixed on the assembly base. Each transformer assembly includes a transformer and copper posts on both sides of the transformer. The copper posts are riveted to the metal terminals on both sides of the transformer. Multiple slots 3 are provided on the assembly base for the copper posts of the transformer assembly to be inserted. The slots have openings on their outer sides, and their shapes match the copper posts. A slider 6 of the same length as the assembly base is slidably mounted on the opening side of the slot. A sliding rod 9 is fixed inside the slider 6 and slidably inserted into the assembly base. A spring is provided between the sliding rod and the assembly base. A cam block 8 is rotatably mounted on the outer side of the slider. The cam block 8 is connected to a lever 7. The rotation of the cam block 8 pushes the slider inward to slide closer to the slot 3, limiting the lateral movement of the copper posts.

[0015] The longitudinal direction of the current transformer is limited by the pressing mechanism 4. Multiple pressing mechanism seats 10 are provided on the inner side of the column groove. The pressing mechanism 4 is provided on the pressing mechanism seat. The pressing mechanism includes a pressing handle 42 and a handle 43 that are movably connected to each other. One end of the pressing handle is provided with a pressing handle connecting end 422 and the other end is provided with a pressing handle pressing end 421. One end of the handle is provided with a handle connecting end 431 and the other end is provided with a handle pressing end 434. The handle is also provided with a handle hinge end 432 near the handle connecting end. The upper part of the pressing handle connecting end 422 is rotatably connected to the handle connecting end 431, and the lower part of the pressing handle connecting end 422 is rotatably connected to the pressing mechanism seat 10. The handle hinge end 432 is rotatably connected to the pressing mechanism seat 10 through a connecting rod 435. The pressing handle pressing end 421 can be pressed onto the current transformer assembly. The pressing mechanism seat is provided with an arc-shaped groove 101. The pressing handle connecting end 422 and the handle hinge end 432 are respectively connected to the two shoulders of the arc-shaped groove. The outer side of the handle is also provided with an arc-shaped protrusion 433 that slides into or out of the arc-shaped groove as the handle rotates.

[0016] The specific working process of this fixture is as follows: The pre-assembled current transformer assembly is inserted into the assembly base, i.e., the copper column is inserted into the column slot 3. The column slots correspond one-to-one with the copper columns of each group, and their shapes are also compatible. However, for easy insertion, there will inevitably be a gap between the copper column and the column slot. The lever 7 is cranked, causing the cam block 8 to rotate. Its protruding part rotates towards the slider 6, pushing the slider towards the assembly base. The slider 6 contacts the copper column in the column slot, positioning it laterally. In the longitudinal direction, pressing down the handle pressing end 434 causes the handle 43 to rotate relative to the pressing mechanism seat. The handle connecting end 431 tilts upward, causing the pressure handle connecting end 422 connected to it to arch upward. The pressure handle pressing end 421 then presses down on the current transformer, limiting the current transformer assembly in the longitudinal direction. During the rotation of the handle, the arc-shaped protrusion 433 on its outer side slides into the arc-shaped groove 101 of the pressing mechanism seat. Even if the pressing end of the handle is released, the pressing handle is still pressed on the transformer because the arc-shaped protrusion is located in the arc-shaped groove.

[0017] After riveting, lift the handle pressing end 434, the arc-shaped protrusion 433 slides out of the arc-shaped groove 101, the handle connecting end 431 and the pressure handle connecting end 422 press down, and the pressure handle pressing end 421 tilts up to release the current transformer. Shake the lever, the protruding part of the cam block no longer abuts the slider, and the slider returns under the action of the spring, so the riveted current transformer assembly can be taken out.

[0018] This utility model is a riveting fixture specifically designed for current transformer components. It has a reasonable structure, is easy to operate, and facilitates riveting by riveting equipment.
