Description

Technical Field

[0001] This utility model relates to the field of electro-erosion protection ring processing technology, and in particular to a riveting indexing plate for electro-erosion protection rings. Background Technology

[0002] An electro-erosion protection ring is a conductive ring structure used to protect motor bearings from electro-erosion damage caused by shaft current. It avoids bearing electro-erosion by safely discharging the shaft current.

[0003] When riveting the carbon fiber bundles inside the electro-erosion protection ring, most of the time it relies on the workers' visual judgment to manually rotate the workpiece to align the riveting holes. Without good auxiliary tools, it is difficult to guarantee the accuracy and consistency of the riveting. Due to the subjectivity and uncertainty of the operation, the quality control of riveting may be difficult, requiring more inspection and testing, which greatly affects the quality and reliability of the product. Moreover, the riveting process is relatively slow, reducing production efficiency.

[0004] Therefore, it is necessary to provide a new riveted indexing plate for electro-erosion protection rings to solve the above problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a riveting indexing plate for an electro-erosion protection ring that facilitates rapid riveting of carbon fiber bundles.

[0006] To solve the above-mentioned technical problems, the riveting indexing plate for the electro-erosion protection ring provided by this utility model includes: a base, an indexing plate rotatably connected inside the base, and multiple slots provided on the side wall of the indexing plate; a fixing block mounted on the surface of the base, a spring installed inside the fixing block; a fixing pin installed inside the fixing block, one end of the fixing pin being fitted with the spring, and the other end of the fixing pin engaging with the slot; symmetrically arranged limiting rods on the surface of the indexing plate, the limiting rods being slidably connected to the electro-erosion protection ring; and multiple riveting holes on the surface of the electro-erosion protection ring, with carbon fiber bundles installed inside the riveting holes.

[0007] Preferably, the indexing plate is internally rotatably connected to and engaged with a T-shaped fixing post, and the bottom end of the base is provided with a funnel-shaped groove, with a screw threaded through the groove and connected to the inside of the fixing post.

[0008] Preferably, the cross-section of the slot is a right-angled trapezoidal structure, and one end of the fixing pin is inclined.

[0009] Preferably, the electro-erosion protection ring is fixed inside the indexing plate, and the side wall of the electro-erosion protection ring is provided with a plurality of mounting holes; the mounting holes communicate with the inside of the riveting holes, and the carbon fiber bundle is installed inside the mounting holes.

[0010] Preferably, the number of mounting holes, riveting holes, and slots are the same and they correspond to each other, and the centers of the corresponding mounting holes, riveting holes, and slots are located on the same straight line.

[0011] Compared with related technologies, the riveted indexing plate for the electro-erosion protection ring provided by this utility model has the following beneficial effects:

[0012] This utility model provides a riveting indexing plate for an electro-erosion protection ring. When riveting the carbon fiber bundle, the electro-erosion protection ring is accurately locked inside the bottom of the indexing plate by the limiting rod. Rotating the indexing plate, when the slot on the side wall of the indexing plate aligns with the fixing pin, the spring extends and pushes the fixing pin to engage the slot, fixing the indexing plate. At this time, the riveting hole aligned with the slot is aligned with the punch at one end of the riveting machine. Opening the riveting machine allows for riveting of the carbon fiber inside the riveting hole. The indexing plate design allows operators to achieve high-precision riveting positioning, improving product quality. The manual rotation operation eliminates the need for complex electrical or pneumatic systems, simplifying operation and making it suitable for small-batch trial production. The fixing pin locks the indexing plate, ensuring stability during the riveting process and reducing errors. Compared to other expensive riveting equipment, the manual riveting indexing plate has lower costs while meeting most conventional riveting needs. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please see Figures 1 to 3 , Figure 1 A schematic diagram of a preferred embodiment of the riveted indexing plate for the electro-erosion protection ring provided by this utility model; Figure 2 for Figure 1The diagram shows the internal structure of the indexing plate. Figure 3 for Figure 1 The diagram shows a top view of the base plate structure. A riveting indexing plate for an electro-erosion protection ring includes a base 1, an indexing plate 2 rotatably connected inside the base 1, and multiple slots 3 on the side wall of the indexing plate 2; a fixing block 4 is mounted on the surface of the base 1, and a spring 11 is installed inside the fixing block 4; a fixing pin 5 is installed inside the fixing block 4, one end of the fixing pin 5 is fitted with the spring 11, and the other end of the fixing pin 5 engages with the slot 3; limiting rods 7 are symmetrically arranged on the surface of the indexing plate 2, and the limiting rods 7 are slidably connected to an electro-erosion protection ring 6; the surface of the electro-erosion protection ring 6 has multiple riveting holes 8, and carbon fiber bundles 10 are installed inside the riveting holes 8. When riveting the carbon fiber bundle 10, the electro-erosion protection ring 6 is accurately locked inside the bottom of the indexing plate 2 by the limiting rod 7. When the indexing plate 2 is rotated, the slot 3 on the side wall of the indexing plate 2 is aligned with the fixing pin 5. At this time, the spring 11 extends and pushes the fixing pin 5 to engage the slot 3, thus fixing the indexing plate 2. At this time, the riveting hole 8 aligned with the slot 3 and the fixing pin 5 is aligned with the punch at one end of the riveting machine. The riveting machine can be turned on to rivet the carbon fiber 10 inside the riveting hole 8.

[0019] The indexing plate 2 is internally rotatably connected to and engaged with a T-shaped fixing post 12. The bottom end of the base 1 has a funnel-shaped groove 14. A screw 13 passes through the groove 14 and is threadedly connected to the inside of the fixing post 12. To rotate the screw 13, it rotates into the inside of the fixing post 12, fixing the fixing post 12 and the indexing plate 2 inside the base 1 and facilitating rotation of the indexing plate 2 within the base 1. When riveting electro-erosion protection rings of different sizes and shapes is required, rotating the screw 13 separates it from the inside of the fixing post 12, allowing the indexing plate 2 to be removed and replaced with the one corresponding to the electro-erosion protection ring.

[0020] The slot 3 has a right-angled trapezoidal cross-section, and one end of the fixing pin 5 is inclined. In order to make the end of the connection between the fixing pin 5 and the slot 3 both beveled, when the indexing plate 2 rotates counterclockwise, the inclined side of the indexing plate 2 presses the inclined side of the fixing pin 5, pushing the fixing pin 5 into the fixing block 4 to compress the spring 11. The fixing pin 5 separates from the slot 3 to facilitate the rotation of the indexing plate 2 and to facilitate the riveting of the next carbon fiber bundle 10.

[0021] The electro-erosion protection ring 6 is fixed inside the indexing plate 2. The side wall of the electro-erosion protection ring 6 is provided with a plurality of mounting holes 9. The mounting holes 9 are connected to the inside of the riveting holes 8, and the carbon fiber bundle 10 is installed inside the mounting holes 9. In order to facilitate the insertion of the carbon fiber bundle 10 through the mounting holes 9 into the inside of the riveting holes 8, one end of the carbon fiber bundle 10 is riveted and fixed inside the riveting holes 8.

[0022] The number of mounting holes 9, riveting holes 8 and slots 3 are the same and correspond to each other. The centers of the corresponding mounting holes 9, riveting holes 8 and slots 3 are located on the same straight line. When the slot 3 is fixed by the fixing pin 5, one of the riveting holes 8 is aligned with the punch of the riveting machine.

[0023] The working principle of the riveting indexing plate for the electro-erosion protection ring provided by this utility model is as follows: The electro-erosion protection ring 6 is placed inside the indexing plate 2, and the limiting rod 7 limits the electro-erosion protection ring 6, so that the riveting hole 8 on the surface of the electro-erosion protection ring 6 is aligned with the slot 3 and the fixing pin 5. The base 1 is installed below the riveting machine, and the riveting hole 8 corresponding to the fixing pin 5 is aligned with the punch at one end of the riveting machine. The carbon fiber bundle 10 is inserted through the mounting hole 9 into the riveting hole 8, and the riveting machine is turned on so that the punch rivets the carbon fiber bundle 10 inside the riveting hole 8. After the carbon fiber bundle 10 is riveted, the indexing plate 2 is rotated counterclockwise. The inclined side of the indexing plate 2 presses against the inclined side of the fixing pin 5, pushing the fixing pin 5 into the fixing block 4 and pressing the spring 11. The fixing pin 5 separates from the slot 3, facilitating the rotation of the indexing plate 2. When the slot 3 on the side wall of the indexing plate 2 aligns with the fixing pin 5 again, the spring 11 extends, pushing the fixing pin 5 to engage the slot 3, thus fixing the indexing plate 2. At this point, the riveting hole 8 aligned with the slot 3 and the fixing pin 5 is aligned with the punch at one end of the riveting machine. The riveting machine can then be opened to rivet the carbon fiber 10 inside the riveting hole 8. The indexing plate design allows operators to achieve high-precision riveting positioning, improving product quality and production efficiency. The manual rotation operation eliminates the need for complex electrical or pneumatic systems, making operation simple and suitable for small-batch trial production. The fixing pin locks the indexing plate, ensuring stability during the riveting process and reducing errors.
