[0001] This utility model relates to the technical field of wire EDM guide wheel assemblies, specifically a combined wire EDM guide wheel assembly. Background Technology

[0002] The wire EDM guide roller is one of the key components of a multi-wire EDM machine, responsible for the transmission of metal wire. Its rotational flexibility, end runout, and radial runout are crucial to the reliability of the entire machine. During the wire EDM process, the wire EDM roller works in conjunction with other components such as the wire spool, tension roller, and guide roller to achieve efficient and precise cutting operations.

[0003] Existing wire EDM guide wheels typically require the spraying of coolant during operation to cool them down. However, this spraying can easily lead to coolant flowing into the inside of the wire EDM guide wheel, causing water ingress and rapid wear, which reduces the practicality of the device. Therefore, there is an urgent need to design a combined wire EDM guide wheel assembly to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a combined wire EDM guide wheel assembly to solve the problem mentioned in the background art that existing wire EDM guide wheels usually require spraying coolant to cool them down during operation. However, spraying coolant can easily cause coolant to flow into the inside of the wire EDM guide wheel, resulting in water ingress and rapid wear of the wire EDM guide wheel, which reduces the practicality of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined wire cutting guide wheel assembly, comprising: a wire cutting guide wheel body, a waterproof structure provided on the outside of the wire cutting guide wheel body, a protective structure provided on the outside of the wire cutting guide wheel body, the waterproof structure including a rotating shaft, the rotating shaft being fixedly connected to the outer wall of the wire cutting guide wheel body, the rotating shaft being installed inside a bearing seat, two sets of bearing seats being provided, the bearing seats being located on both sides of the wire cutting guide wheel body, bearing sleeves being installed on the outside of the bearing seats, and a rubber ring being fitted on the outside of the rotating shaft.

[0006] Preferably, a sealing shell is installed on the side of the bearing housing near the wire cutting guide wheel body. The sealing shell is arranged in a circular shape, and a vent is opened at the bottom end of the sealing shell.

[0007] Preferably, the outer wall of the casing is fixedly connected to an installation rod, and the bearing sleeve has a groove corresponding to the installation rod inside, so that the installation rod can be installed into the groove inside the bearing sleeve.

[0008] Preferably, the protective structure includes a protective shell, which is installed outside the bearing sleeve and on both sides of the wire cutting guide wheel body.

[0009] Preferably, the protective shell has a positioning groove inside, and the bearing sleeve has a positioning ball fixedly connected to its outer wall, the positioning ball being slidably disposed inside the positioning groove.

[0010] Preferably, a fastening ring is installed on the outside of the protective shell, a slide rail is provided inside the protective shell, a positioning plate is fixedly connected to the inner wall of the fastening ring, and the positioning plate on the inner wall of the fastening ring is slidably disposed inside the slide rail.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This modular wire EDM guide wheel assembly features a waterproof structure. By converting the integral structure into a modular design, it facilitates easy replacement of the guide wheel assembly. Simultaneously, a sealing shell is installed at the connection points between the wire EDM guide wheel body, the rotating shaft, and the bearing housing to prevent coolant or other liquids sprayed during operation from entering the connection between the wire EDM guide wheel body and the rotating shaft, thus avoiding rapid wear. Coolant sprayed onto the wire EDM guide wheel enters the cavity between the bearing sleeve and the bearing housing. During normal operation of the wire EDM guide wheel assembly, the coolant or other liquids inside the cavity can be discharged through the drain port, preventing accumulation inside the cavity and subsequent wear at the connection point. This design achieves waterproof protection at the connection point between the wire EDM guide wheel body and the rotating shaft, preventing coolant from entering the connection point when the wire EDM guide wheel is cooled by spraying coolant, thus improving the practicality and waterproofing effect of the device.

[0013] 2. This combined wire EDM guide wheel assembly is equipped with a protective structure. When using this combined wire EDM guide wheel assembly, two sets of protective shells can be installed outside the bearing sleeve to protect the entire device. When the protective shell is installed outside the bearing sleeve, it can be positioned by sliding the positioning ball inside the positioning groove, making the installation of the protective shell outside the bearing sleeve more convenient. The fastening ring is sleeved outside the protective shell, which can improve the connection and tightness between the protective shell and the bearing sleeve. Through this design, the combined wire EDM guide wheel assembly can be externally protected by the protective shell. At the same time, the protective shell can also be used to initially prevent coolant from entering the combined wire EDM guide wheel assembly, improving the practicality and protective effect of the device.

Detailed Implementation

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Please see Figure 1-5 One embodiment provided by this utility model:

[0022] A combined wire EDM guide wheel assembly includes: a wire EDM guide wheel body 111, a waterproof structure 2 externally disposed on the wire EDM guide wheel body 111, and a protective structure 3 externally disposed on the wire EDM guide wheel body 111. The waterproof structure 2 includes a rotating shaft 211, which is fixedly connected to the outer wall of the wire EDM guide wheel body 111. The rotating shaft 211 is installed inside a bearing seat 212. Two sets of bearing seats 212 are provided, located on both sides of the wire EDM guide wheel body 111. Bearing sleeves are installed on the outside of the bearing seats 212. 213. A rubber ring 216 is fitted around the outside of the rotating shaft 211. This design allows the modular wire EDM guide wheel assembly to be transformed from an integral structure into a split structure, making it convenient to replace the wire EDM guide wheel assembly. At the same time, a cover 214 is provided at the connection between the wire EDM guide wheel body 111, the rotating shaft 211 and the bearing seat 212 to prevent water from entering the connection between the wire EDM guide wheel body 111 and the rotating shaft 211 during use, which would cause the wire EDM guide wheel to wear rapidly.

[0023] Furthermore, a cover 214 is installed on the side of the bearing housing 212 near the wire EDM guide wheel body 111. The cover 214 is circular in shape, and a drain 215 is provided at the bottom end of the cover 214. Through this design, the coolant sprayed on the wire EDM guide wheel enters the cavity between the bearing sleeve 213 and the bearing housing 212. At this time, the wire EDM guide wheel assembly rotates normally, and the coolant and other liquids that have entered the cavity can be discharged from the drain 215, preventing them from accumulating inside the cavity and causing coolant to enter the connection between the wire EDM guide wheel body 111 and the rotating shaft 211 and causing wear.

[0024] Furthermore, an installation rod 217 is fixedly connected to the outer wall of the casing 214, and a groove corresponding to the installation rod 217 is opened inside the bearing sleeve 213. The installation rod 217 can be installed into the groove opened inside the bearing sleeve 213. With this design, when the bearing sleeve 213 and the casing 214 are installed, the installation rod 217 can be used for positioning, so that the installation rod 217 enters the groove opened inside the bearing sleeve 213, and the bearing sleeve 213 and the casing 214 can be easily assembled.

[0025] Furthermore, the protective structure 3 includes a protective shell 311, which is installed outside the bearing sleeve 213. The protective shell 311 is installed on both sides of the wire cutting guide wheel body 111. With this design, when using the combined wire cutting guide wheel assembly, two sets of protective shells 311 can be installed outside the bearing sleeve 213 to protect the entire device.

[0026] Furthermore, a positioning groove 312 is provided inside the protective shell 311, and a positioning ball 313 is fixedly connected to the outer wall of the bearing sleeve 213. The positioning ball 313 can be slidably disposed inside the positioning groove 312. With this design, when the protective shell 311 is installed outside the bearing sleeve 213, the positioning ball 313 can be used to slide inside the positioning groove 312 for positioning, making it more convenient to install the protective shell 311 outside the bearing sleeve 213.

[0027] Furthermore, a fastening ring 314 is installed on the outside of the protective shell 311, and a slide rail 315 is provided inside the protective shell 311. A positioning plate is fixedly connected to the inner wall of the fastening ring 314. The positioning plate on the inner wall of the fastening ring 314 can be slidably arranged inside the slide rail 315. Through this design, the fastening ring 314 is sleeved on the outside of the protective shell 311, and the fastening ring 314 can be used to improve the connection tightness between the protective shell 311 and the bearing sleeve 213.

[0028] Working principle:

[0029] When using this modular wire EDM guide wheel assembly, its structure is designed to be either integral or modular, facilitating easy replacement. Simultaneously, a sealing shell 214 is installed at the connection between the wire EDM guide wheel body 111, the rotating shaft 211, and the bearing seat 212 to prevent water from entering the connection between the wire EDM guide wheel body 111 and the rotating shaft 211 during use, thus preventing rapid wear of the wire EDM guide wheel. Coolant sprayed onto the wire EDM guide wheel enters the cavity between the bearing sleeve 213 and the bearing seat 212. During normal rotation of the wire EDM guide wheel assembly, the coolant and other liquids inside the cavity can be discharged through the drain 215, preventing accumulation inside the cavity and thus preventing coolant from entering the connection between the wire EDM guide wheel body 111 and the rotating shaft 212 and causing wear.

[0030] When using this combined wire EDM guide wheel assembly, two sets of protective shells 311 can be installed on the outside of the bearing sleeve 213 to protect the entire device. When the protective shell 311 is installed on the outside of the bearing sleeve 213, the positioning ball 313 can slide inside the positioning groove 312 for positioning, making it easier to install the protective shell 311 on the outside of the bearing sleeve 213. The fastening ring 314 is sleeved on the outside of the protective shell 311, which can be used to improve the connection and tightness between the protective shell 311 and the bearing sleeve 213. The operation is now complete.
