Description

Technical Field

[0001] This utility model relates to the field of wire EDM guide wheel technology, and in particular to a wire EDM guide wheel structure. Background Technology

[0002] Wire EDM uses a continuously moving thin metal wire as an electrode to remove metal from the workpiece and cut it into shape using pulsed spark discharge. It is mainly used to process various complex and precision small workpieces. Generally, a molybdenum wire or other electrode wire is wound around a guide wheel, which drives the wire to move through the workpiece and cut it.

[0003] The existing technology requires the removal of multiple bolts when replacing the guide wheel, which is a cumbersome operation and results in the drawback of inconvenient guide wheel replacement. Utility Model Content

[0004] In order to overcome the above-mentioned defects in the prior art, this utility model provides a wire cutting guide wheel structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a wire cutting guide wheel structure, including a connecting frame, two sets of mounting frames are fixedly installed at the front end of the connecting frame, a set of positioning holes are provided on the front, lower and upper sides of the mounting frame, positioning columns are slidably installed in the positioning holes, a mounting hole is provided in the middle of the mounting frame, a guide wheel is slidably installed in the mounting hole, and a mating hole is provided on the outer side of the guide wheel, the mating hole is mated with the positioning column.

[0006] Furthermore, the rear end of the positioning post is provided with a round head, which is fitted into a mating hole for installation.

[0007] Furthermore, a base plate is fixedly mounted at the front end of the positioning column, and a set of springs is fixedly connected between the base plate and the outer side of the mounting frame.

[0008] Furthermore, each of the left and right sides of the guide wheel is provided with a set of threaded portions, and an end cap is installed on the outer side of the threaded portions.

[0009] The beneficial effects of this utility model are as follows: by inserting the guide wheel into the mounting hole in the middle of the mounting bracket, and then, during the movement of the guide wheel, the positioning column expands outward under the action of the round head until the positioning columns on both sides are fitted together with the mating holes, thus completing the positioning and installation of the guide wheel. Then, the end caps on both sides are tightened to complete the assembly of the guide wheel, reducing the bolt tightening process and improving disassembly efficiency. Attached Figure Description

[0016] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0017] like Figures 1 to 4 As shown, this utility model includes a connecting frame 1, with two sets of mounting brackets 2 fixedly installed at the front end of the connecting frame 1. The mounting bracket 2 has a mounting hole 21 in the middle, and a guide wheel 6 is slidably installed in the mounting hole 21. A set of positioning holes 22 are provided on the front, lower and upper sides of the mounting bracket 2. A positioning post 3 is slidably installed in the positioning hole 22. A round head 31 is provided at the rear end of the positioning post 3. A mating hole 62 is provided on the outer side of the guide wheel 6, and the round head 31 is mated with the mating hole 62.

[0018] like Figure 1 and Figure 4 As shown, the front end of the positioning column 3 is fixedly mounted on the base plate 4, and a set of springs 5 ​​are fixedly connected between the base plate 4 and the outer side of the mounting frame 2. The front end of the springs 5 ​​is fixedly mounted on the outer side wall of the mounting frame 2, and the rear end of the springs 5 ​​is fixedly mounted on the base plate 4.

[0019] like Figure 1 and Figure 2 As shown, each of the left and right sides of the guide wheel 6 is provided with a set of threaded portions 61, and an end cap 7 is installed on the outer side of the threaded portions 61. The end cap 7 is used to limit the left and right sides of the guide wheel 6.

[0020] In use, this utility model involves inserting the guide wheel 6 into the mounting hole 21 in the middle of the mounting bracket 2. As the guide wheel 6 moves, the positioning pin 3 expands outward under the action of the round head 31 until the positioning pins 3 on both sides are fitted together with the mating hole 62, thus completing the positioning and installation of the guide wheel 6. Then, the end caps 7 on both sides are tightened to complete the assembly of the guide wheel 6, reducing the bolt tightening process and improving disassembly efficiency.

[0021] The above embodiments are merely exemplary embodiments of the present utility model and are not intended to limit the present utility model.
