Description

Technical Field

[0001] The utility model relates to the field of hardware processing, in particular to a waterway processing structure for a pull rod nut. Background Technique

[0002] When processing the pull rod nut shown in Fig. 1, an installation hole for arranging a rod member penetrates through the middle of the pull rod nut, and the installation hole penetrates through the pull rod nut along the diameter direction of the pull rod nut. A waterway is also arranged in the pull rod nut in a circumferential manner around the installation hole, and the waterway is used to cool the pull rod nut in the working state and the tool installed at the end of the pull rod nut.

[0003] However, during processing, the pull rod nut is divided into four identical quarter cylinders arranged symmetrically, and then waterways are processed at corresponding positions. Finally, the four quarter cylinders are fixed together by welding, so that the four quarter cylinders form a complete pull rod nut. However, the circumferential ends and the longitudinal ends of the separately processed waterways need to be aligned with each other. A misaligned setting will cause the diameter of the waterway to become smaller, resulting in the processed waterway not meeting the standard. Therefore, other processing structures more suitable for processing pull rod nuts with complex internal waterways are needed to reduce the situation where it is difficult for the separately processed waterway structures to align with each other. Summary of the Utility Model

[0004] The utility model provides a waterway processing structure for a pull rod nut, which can enable the processed waterway to avoid the installation hole, and at the same time, can avoid the situation where the semi-cylindrical waterway structures are misaligned with each other.

[0005] The waterway processing structure for a pull rod nut provided by the utility model adopts the following technical scheme:

[0006] A waterway processing structure for a pull rod nut includes a waterway. The waterway is in a square ring shape, and an installation hole penetrates through the central inner ring of the waterway. The waterway includes a transverse path and a longitudinal path, the transverse path is communicated with the longitudinal path, both the transverse path and the longitudinal path penetrate through the pull rod nut, a first hole-sealing member is arranged at the open end of the transverse path, and a second hole-sealing member is arranged at the open end of the longitudinal path.

[0007] During processing, drill through the tie rod nut along the length direction of the mounting hole, thereby completing the processing of the mounting hole. Then, drill holes from the side wall of the tie rod nut to the inside of the tie rod nut along the length direction of the cross path. Two holes communicating with the cross path should be drilled. The two holes communicating with the cross path are respectively arranged on both sides of the mounting hole. Then, use the first sealing member to seal the opening at the end of the cross path and fix the first sealing member, so that the cooling water is not easily leaked from the end of the cross path when flowing into the cross path, thereby completing the processing of the cross path. Drill two holes from the other side wall of the tie rod nut to the inside of the tie rod nut along the length direction of the longitudinal path, so that the two holes drilled in the other direction communicate with both cross paths, thereby forming a square annular water path. Then, use the second sealing member to seal the opening at the end of the longitudinal path and fix the second sealing member, so that the cooling water is not easily leaked from the end of the longitudinal path after flowing into the longitudinal path, thereby completing the processing of the longitudinal path.

[0008] The processing of the mounting hole, the cross path and the longitudinal path can all be carried out from the outside of the complete tie rod nut, and the mounting hole, the cross path and the longitudinal path can all be formed at one time, reducing the steps of splicing after the tie rod nut is divided into multiple pieces, avoiding the subsequent splicing trouble, simplifying the processing structure of the water path of the tie rod nut, and making the processed water path structure smooth and the inner side wall smooth.

[0009] Preferably, the longitudinal path and the cross path are perpendicular to each other.

[0010] The perpendicularity of the longitudinal path and the cross path reduces the obstruction of the inner side wall of the water path to the water flow. Generally, high-pressure water is passed through the water path. If the water flow is obstructed, the water pressure of the water flow will be buffered, resulting in a worse water outlet effect than the expected effect. At the same time, the continuous impact of the water flow on the inner wall of the water path is likely to cause the side wall of the tie rod nut to be thinned by stamping.

[0011] Preferably, the second sealing member is located at the end of the tie rod nut along the length direction; the straight line where the length direction of the mounting hole is located is perpendicular to the straight line where the length direction of the longitudinal path is located; the straight line where the length direction of the mounting hole is located is perpendicular to the straight line where the length direction of the cross path is located.

[0012] The length direction of the mounting hole is perpendicular to the length direction of the tie rod nut, restricting the length directions of the longitudinal path and the cross path and restricting the penetration entrance of the longitudinal path, so that the length direction of the longitudinal path is consistent with the length direction of the tie rod nut. Therefore, when the water flow flows in the longitudinal path, the longitudinal path is in a vertical state, and the water flow can fall freely, further reducing the obstruction of the inner wall of the water path to the water flow and making the cooling water more easily flow in the water path.

[0013] Preferably, the first sealing member and the second sealing member are metal columns. The diameter of the first sealing member is set corresponding to the diameter of the cross path, the diameter of the second sealing member is set corresponding to the diameter of the longitudinal path, the peripheral wall of the first sealing member is tightly abutted against the inner peripheral wall of the end of the cross path, and the outer peripheral wall of the second sealing member is tightly abutted against the inner peripheral wall of the end of the longitudinal path.

[0014] Since both the cross - path and the longitudinal path have a circular cross - section, their ends are cylindrical surfaces. The ends of the cross - path and the longitudinal path are sealed by cylindrical metal posts as the first sealing member and the second sealing member. By restricting the diameter of the metal posts, the ends of the cross - path and the longitudinal path can be sealed, making it difficult for the cooling water to leak out from the ends of the cross - path and the longitudinal path.

[0015] Preferably, a welding layer is provided between the outer peripheral wall of the first sealing member and the inner peripheral wall of the end of the cross - path, and a welding layer is also provided between the outer peripheral wall of the second sealing member and the inner peripheral wall of the end of the longitudinal path.

[0016] The provision of the welding layer can fill the gap between the first sealing member and the inner peripheral wall of the end of the cross - path, can also seal the gap between the second sealing member and the inner peripheral wall of the end of the longitudinal path, and can also fix the first sealing member and the second sealing member, enabling the first sealing member and the second sealing member to firmly seal the ends of the cross - path and the longitudinal path.

[0017] Preferably, the pull - rod nut is provided with a water inlet hole and a water outlet hole. The longitudinal path passes through one end of the pull - rod nut where the water outlet hole is located, and the end of the longitudinal path away from the water outlet hole is closed. The longitudinal path passes through the end of the cross - path near the second sealing member. A connection hole for communicating with the longitudinal path is opened on one side of the other cross - path near the water outlet hole, and the longitudinal path does not pass through the cross - path away from the second sealing member.

[0018] The longitudinal path is machined from the end of the pull - rod nut along the length direction, making it easier to clamp the pull - rod nut when machining the longitudinal path and making it easier to find the inlet position of the longitudinal path.

[0019] Preferably, one end of the cross - path passes through the pull - rod nut, and the other end of the cross - path is closed. The cross - path passes through the longitudinal path near the first sealing member. A connection hole for communicating with the longitudinal path is opened on one side of the other longitudinal path near the first sealing member, and the cross - path does not pass through the cross - path away from the first sealing member.

[0020] Preferably, the end wall of the second sealing member is a flat surface flush with the end of the pull - rod nut.

[0021] After the second sealing member and the end of the pull - rod nut are welded to each other, they form a smooth flat surface. The side wall of the second sealing member and the pull - rod nut is flat and smooth, so that it is difficult to see the traces of welding and perforation on the appearance, making it difficult to remove the second sealing member, which is beneficial to improving the stability of the fixation of the second sealing member.

[0022] Preferably, the side of the first sealing member close to the outer side wall of the pull - rod nut is an arc surface, and the end wall of the welding layer smoothly transitions to the end wall of the first sealing member and the outer side wall of the pull - rod nut.

[0023] The end of the first hole-sealing member is provided with an arc surface that can be smoothly transitioned through the end wall of the welding layer, so that after welding, the side wall of the first hole-sealing member and the pull rod nut are flat and smooth, making it difficult to see the traces of welding and perforation in appearance, making the first hole-sealing member not easy to be taken out, which is beneficial to improving the fixing stability of the first hole-sealing member.

[0024] To sum up, the utility model includes the following beneficial technical effects:

[0025] During processing, drill through the pull rod nut along the length direction of the installation hole to complete the processing of the installation hole. Then drill holes from the side wall of the pull rod nut to the inside of the pull rod nut along the length direction of the cross path. There should be two holes communicating with the cross path, and the two holes communicating with the cross path are respectively arranged on both sides of the installation hole. Then use the first hole-sealing member to seal the opening at the end of the cross path and fix the first hole-sealing member, so that the cooling water is not easy to leak out from the end of the cross path when flowing into the cross path, thus completing the processing of the cross path. Drill two holes from the other side wall of the pull rod nut to the inside of the pull rod nut along the length direction of the longitudinal path, so that the two holes drilled in the other direction communicate with both cross paths, thus forming a square ring-shaped water path. Then use the second hole-sealing member to seal the opening at the end of the longitudinal path and fix the second hole-sealing member, so that the cooling water is not easy to leak out from the end of the longitudinal path when flowing into the longitudinal path, thus completing the processing of the longitudinal path.

[0026] For the processing of the installation hole, cross path and longitudinal path, it can be carried out from the outside of the complete pull rod nut, and the installation hole, cross path and longitudinal path can be formed at one time, reducing the steps of splicing after the pull rod nut is divided into multiple pieces, avoiding the subsequent splicing trouble, simplifying the processing structure of the water path of the pull rod nut, and making the processed water path structure smooth and the inner side wall smooth.

[0030] The following further describes the utility model in detail with reference to Figures 1-2.

[0031] An embodiment of the utility model discloses a water path processing structure of a pull rod nut.

[0032] Referring to FIG. 1, a processing structure for the water channel 1 of a tie rod nut includes a water channel 1. The water channel 1 is in a square ring shape. The mounting hole 2 penetrates through the central inner ring of the water channel 1. The water channel 1 includes a transverse path 3 and a longitudinal path 4. The transverse path 3 communicates with the longitudinal path 4. Both the transverse path 3 and the longitudinal path 4 penetrate through the tie rod nut 5. A first hole-sealing member 6 is provided at the open end of the transverse path 3, and a second hole-sealing member 7 is provided at the open end of the longitudinal path 4.

[0033] During processing, drill through the tie rod nut 5 along the length direction of the mounting hole 2 to complete the processing of the mounting hole 2. Then, drill holes from the side wall of the tie rod nut 5 towards the inside of the tie rod nut 5 along the length direction of the transverse path 3. Two holes communicating with the transverse path 3 should be drilled. The two holes communicating with the transverse path 3 are respectively arranged on both sides of the mounting hole 2. Then, use the first hole-sealing member 6 to seal the opening at the end of the transverse path 3 and fix the first hole-sealing member 6, so that the cooling water flowing into the transverse path 3 is not likely to leak from the end of the transverse path 3, thus completing the processing of the transverse path 3. Drill two holes from another side wall of the tie rod nut 5 towards the inside of the tie rod nut 5 along the length direction of the longitudinal path 4, so that the two holes drilled in the other direction communicate with both transverse paths 3 to form a square-ring-shaped water channel 1. Then, use the second hole-sealing member 7 to seal the opening at the end of the longitudinal path 4 and fix the second hole-sealing member 7, so that the cooling water flowing into the longitudinal path 4 is not likely to leak from the end of the longitudinal path 4, thus completing the processing of the longitudinal path 4.

[0034] For the processing of the mounting hole 2, the transverse path 3 and the longitudinal path 4, it can be carried out from the outside of the complete tie rod nut 5. Moreover, the mounting hole 2, the transverse path 3 and the longitudinal path 4 can be formed in one step, reducing the steps of splicing after the tie rod nut 5 is divided into multiple pieces, avoiding subsequent splicing troubles, simplifying the processing structure of the water channel 1 of the tie rod nut, and making the formed water channel 1 structure smooth and the inner side wall smooth.

[0035] Referring to FIG. 1 and FIG. 2, in this embodiment, the longitudinal path 4 is perpendicular to the transverse path 3.

[0036] The perpendicularity between the longitudinal path 4 and the transverse path 3 reduces the obstruction of the inner side wall of the water channel 1 to the water flow. Generally, high-pressure water flows through the water channel 1. If the water flow is obstructed, the water pressure of the water flow will be buffered, resulting in a worse water outlet effect than the expected effect. At the same time, the continuous impact of the water flow on the inner wall of the water channel 1 is likely to cause the side wall of the tie rod nut 5 to be thinned by stamping.

[0037] Referring to FIG. 1 and FIG. 2, in this embodiment, the second hole-sealing member 7 is located at the end of the tie rod nut 5 along the length direction; the straight line where the length direction of the mounting hole 2 is located is perpendicular to the straight line where the length direction of the longitudinal path 4 is located; the straight line where the length direction of the mounting hole 2 is located is perpendicular to the straight line where the length direction of the transverse path 3 is located.

[0038] The length direction of the mounting hole 2 is perpendicular to the length direction of the tie rod nut 5, restricting the length directions of the longitudinal path 4 and the transverse path 3 and restricting the penetration inlet of the longitudinal path 4, so that the length direction of the longitudinal path 4 is consistent with the length direction of the tie rod nut 5. Therefore, when water flows in the longitudinal path 4, the longitudinal path 4 is in a vertical state, and the water can fall freely, further reducing the obstruction of the inner wall of the water path 1 to the water flow, making it easier for the cooling water to flow in the water path 1.

[0039] Referring to FIGS. 1 and 2, in this embodiment, the first sealing member 6 and the second sealing member 7 are metal columns. The diameter of the first sealing member 6 is set corresponding to the diameter of the transverse path 3, and the diameter of the second sealing member 7 is set corresponding to the diameter of the longitudinal path 4. The peripheral wall of the first sealing member 6 abuts against the inner peripheral wall of the end of the transverse path 3, and the outer peripheral wall of the second sealing member 7 abuts against the inner peripheral wall of the end of the longitudinal path 4.

[0040] Since the cross-sections of both the transverse path 3 and the longitudinal path 4 are circular, their ends are cylindrical surfaces. By using cylindrical metal columns as the first sealing member 6 and the second sealing member 7 to seal the ends of the transverse path 3 and the longitudinal path 4, restricting the diameter of the metal columns can seal the ends of the transverse path 3 and the longitudinal path 4, making it difficult for the cooling water to leak out from the ends of the transverse path 3 and the longitudinal path 4.

[0041] Referring to FIGS. 1 and 2, in this embodiment, a welding layer 8 is provided between the outer peripheral wall of the first sealing member 6 and the inner peripheral wall of the end of the transverse path 3, and a welding layer 8 is also provided between the outer peripheral wall of the second sealing member 7 and the inner peripheral wall of the end of the longitudinal path 4.

[0042] The setting of the welding layer 8 can fill the gap between the first sealing member 6 and the inner peripheral wall of the end of the transverse path 3, can also seal the gap between the second sealing member 7 and the inner peripheral wall of the end of the longitudinal path 4, and can also fix the first sealing member 6 and the second sealing member 7, so that the first sealing member 6 and the second sealing member 7 can stably seal the ends of the transverse path 3 and the longitudinal path 4.

[0043] Referring to FIGS. 1 and 2, in this embodiment, the tie rod nut 5 is provided with a water inlet 9 and a water outlet 10. The longitudinal path 4 penetrates through one end of the tie rod nut 5 where the water outlet 10 is provided. The end of the longitudinal path 4 away from the water outlet 10 is closed. The longitudinal path 4 penetrates through the end of the transverse path 3 close to the second sealing member 7. A connection hole 11 for communicating with the longitudinal path 4 is opened on one side of the other transverse path 3 close to the water outlet 10. The longitudinal path 4 does not penetrate through the transverse path 3 away from the second sealing member 7.

[0044] Machining the longitudinal path 4 from the end of the tie rod nut 5 along the length direction makes it easier to clamp the tie rod nut 5 when machining the longitudinal path 4 and makes it easier to find the inlet position of the longitudinal path 4.

[0045] Referring to FIGS. 1 and 2, in this embodiment, one end of the horizontal path 3 penetrates through the pull rod nut 5, the other end of the horizontal path 3 is closed, the horizontal path 3 penetrates through the vertical path 4 near the first hole-sealing member 6, and a connection hole 11 for communicating with the vertical path 4 is formed on one side of the other vertical path 4 near the first hole-sealing member 6. The horizontal path 3 does not penetrate through the horizontal path 3 far from the first hole-sealing member 6.

[0046] Referring to FIGS. 1 and 2, in this embodiment, the end wall of the second hole-sealing member 7 is a flat surface flush with the end of the pull rod nut 5.

[0047] After the second hole-sealing member 7 and the end of the pull rod nut 5 are welded to each other, they form a smooth flat surface. The side wall of the second hole-sealing member 7 and the pull rod nut 5 is flat and smooth, so that it is difficult to see the traces of welding and perforation on the appearance, making the second hole-sealing member 7 not easy to take out, which is beneficial to improving the fixing stability of the second hole-sealing member 7.

[0048] The first hole-sealing member 6, the second hole-sealing member 7 and the body of the pull rod nut 5 are made of the same material.

[0049] The arrangement of the first hole-sealing member 6, the second hole-sealing member 7 and the body made of the same material makes it easier to weld and fix the first hole-sealing member 6 and the second hole-sealing member 7 on the pull rod nut 5, which is beneficial to improving the installation stability of the first hole-sealing member 6 and the second hole-sealing member 7.

[0050] Referring to FIGS. 1 and 2, in this embodiment, one side of the first hole-sealing member 6 close to the outer side wall of the pull rod nut 5 is an arc surface, and the end wall of the welding layer 8 smoothly transitions to the end wall of the first hole-sealing member 6 and the outer side wall of the pull rod nut 5.

[0051] The end of the first hole-sealing member 6 is provided with an arc surface that can be smoothly transitioned by the end wall of the welding layer 8. After welding, the side walls of the first hole-sealing member 6 and the pull rod nut 5 are flat and smooth, so that it is difficult to see the traces of welding and perforation on the appearance, making the first hole-sealing member 6 not easy to take out, which is beneficial to improving the fixing stability of the first hole-sealing member 6.

[0052] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present invention should be covered within the protection scope of the present invention.
