Description

Technical Field

[0001] The utility model relates to the technical field of wire cutting, in particular to a single-side integral wire threading guide wheel seat for wire cutting equipment. Background Art

[0002] In order to facilitate the installation of molybdenum wire on the guide wheel, some existing wire cutting guide wheel seats are provided with a guiding mechanism on one side of the guide wheel seat. For example, a wire cutting guide wheel seat with a guiding ring disclosed in CN204724969U, and a wire threading guide wheel seat (CN209681357U) previously applied by the applicant.

[0003] However, the wire guiding mechanisms of such guide wheel seats are separately arranged from the guide wheel seat body and are formed by separate processing. The production is inconvenient. After being assembled together, there will be a certain deviation between the wire guiding mechanism and the guide wheel seat body, affecting the wire threading accuracy. Especially after being used for a period of time, the wire guiding mechanism will become loose from the guide wheel seat body, affecting the service life. Summary of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the utility model provides a single-side integral wire threading guide wheel seat with simple structure, convenient production, firmness and reliability, accurate position degree and long service life.

[0005] The utility model is realized by the following technical solutions:

[0006] A single-side integral wire threading guide wheel seat includes a guide wheel seat main body. One end of the guide wheel seat main body is integrally formed with a wire guiding body. The wire guiding body is a ring-shaped hollow structure. A guiding groove for embedding molybdenum wire and guiding it is provided on the outer wall of the wire guiding body along its circumferential direction. The bottom end of the guiding groove has a through groove that penetrates the inner wall of the wire guiding body and can allow the molybdenum wire to pass through and enter the inner cavity of the wire guiding body. A plurality of water leakage holes penetrating the wall thickness of the wire guiding body are provided on the outer wall of the wire guiding body along its circumferential direction.

[0007] Wherein, the diameter of the circle where the wire guiding body is located is larger than the diameter of the circle where the guide wheel seat main body is located.

[0008] Since when threading the wire, the molybdenum wire is only partially embedded in the guide wheel, therefore, the guiding groove is integrally designed as an arc shape, and the two ends of the guiding groove are not connected.

[0009] In order to facilitate the inward guiding of the molybdenum wire and accurately embed it on the guide wheel, the guiding groove has two oppositely arranged conical guiding surfaces, and the bottom ends of the two conical guiding surfaces have a through groove.

[0010] In order to reduce the contact area between the inner wall of the wire guiding body and the guide wheel as much as possible, thereby reducing the resistance of the guide wheel, the inner wall of the wire guiding body has two oppositely arranged conical surfaces, and a ring-shaped boss that can be in clearance fit with the inner guide wheel is formed between the two conical surfaces. The through groove penetrates the inner end surface of the ring-shaped boss.

[0011] The beneficial effects of the present utility model are as follows: By integrally forming the guide wheel seat body and the wire guiding body, the one-sided integral wire threading easy guide wheel seat is more convenient to manufacture, has higher overall firmness and more accurate position accuracy, ensures the processing accuracy of the equipment, and greatly improves the service life of the guide wheel seat.

[0013] Figure 2 is a cross-sectional view of the one-sided integral wire threading easy guide wheel seat of the present utility model. Detailed Embodiments

[0014] The following elaborates on the preferred embodiments of the present utility model in conjunction with the attached drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. The directional terms mentioned in the present utility model, such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom", etc., are only references to the directions of the attached drawings. Therefore, the directional terms used are for the purpose of explaining and understanding the present utility model, rather than for limiting the present utility model.

[0015] As Figure 1 , Figure 2 shown, a one-sided integral wire threading easy guide wheel seat includes a guide wheel seat body 1 in a cylindrical shape. A main shaft and bearings are installed inside the guide wheel seat body 1. One end of the guide wheel seat body 1 is integrally formed with a wire guiding body 2. The wire guiding body 2 is a ring-shaped hollow structure. The diameter of the circle where the wire guiding body 2 is located is larger than the diameter of the circle where the guide wheel seat body 1 is located. A guide wheel is installed inside the wire guiding body 2. A guiding groove 3 for embedding and guiding a molybdenum wire is provided along the circumferential direction of the outer wall of the wire guiding body 2. The guiding groove 3 is arc-shaped as a whole, and its two ends are not connected. The radian of the guiding groove 3 is greater than 180 degrees. The guiding groove 3 has two oppositely arranged conical guiding surfaces. At the bottom ends of the two conical guiding surfaces, there is a through groove 5 for the molybdenum wire to pass through and enter the inner cavity of the wire guiding body 2. The through groove 5 is located outside the guide wheel, and its width is slightly smaller than the width of the molybdenum wire groove of the guide wheel. A plurality of water leakage holes 4 penetrating the wall thickness of the wire guiding body 1 are provided along the circumferential direction of the outer wall of the wire guiding body 2;

[0016] In addition, the inner wall of the wire guiding body 2 has two oppositely arranged conical surfaces. A ring-shaped convex platform 8 that can be in clearance fit with the inner guide wheel is formed between the first conical surface 6 on the inner side and the second conical surface 7 on the outer side. The through groove 5 penetrates the inner end surface of the ring-shaped convex platform 8. The width of the ring-shaped convex platform 8 is slightly larger than the width of the molybdenum wire groove of the guide wheel, so that the contact surface between the guide wheel and the ring-shaped convex platform 8 is small, and thus the resistance during rotation is small.

[0017] The single-sided integral wire threading guide wheel seat is more convenient to manufacture and has higher overall firmness by integrally forming the guide wheel seat body 1 and the wire guiding body 2. Through the designed guiding groove 3, the wire threading of the molybdenum wire can be guided. During installation, the molybdenum wire can be accurately embedded into the molybdenum wire groove of the guide wheel through the guiding of the guiding groove 3 and the through groove 5, realizing easy wire threading and more accurate position accuracy. Since it is an integrally formed structure, even after a long time of use, the wire threading accuracy will not be affected. In addition, the designed water leakage hole 4 can timely discharge the cutting fluid during use.

[0018] The above embodiments only represent several implementation modes of the present invention, and the description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
