[0026] Please refer to the attached Figure 1-5 , is a thread repair tool set for air and oil release disclosed by the utility model.
[0027] Embodiment 1:
[0028] The utility model mainly comprises: a discharge valve 1 and a connecting piece 2 screwed to the tail end of the discharge valve 1, and also comprises a first drill bit 3 for enlarging the diameter of an original air release hole and an oil release hole and a second drill bit 4 for tapping the enlarged air release hole and the oil release hole. The diameter of one end of the first drill bit 3 for enlarging the hole diameter is equal to the diameter of one end of the second drill bit 4 for tapping. The end of the second drill bit 4 for tapping and the end of the connecting piece 2 away from the discharge valve 1 are provided with threads with equal diameters and densities, so that the connecting piece 2 is screwed to the tapped screw hole of the second drill bit 4.
[0029] It should be noted that tapping is a metalworking process that involves using a specific tool, such as a tapping plate or a tap, to rotate and press on the surface of a metal material to form an external thread. This process is also known as thread tapping, which is a processing method used to cut threads on a workpiece, commonly used in the manufacture of mechanical parts and molds and other products.
[0030] The connecting member 2 has a nut 21 at one end for threading the discharge valve 1 , and a screw rod 22 at the other end. The nut 21 and the screw rod 22 are coaxially arranged.
[0031] It should be noted that when the original threads of the air bleed hole and the oil drain hole are damaged, the first drill bit 3 is used to expand the threads of the original air bleed hole and the oil drain hole, and then the second drill bit 4 is used to tap the threads. The air bleed hole and the oil drain hole after tapping are screwed to the connecting parts, and then the discharge valve is screwed to perform air and oil release.
[0032] The end surface of the screw rod 22 away from the nut 21 is provided with a first through hole 220 which penetrates the central axis. A sealing ring 23 is sleeved on the outer periphery of the screw rod 22 .
[0033] It should be noted that the bottom surface of the free end of the screw rod 22 is flat, and cooperates with the sealing gasket 23 to play a sealing role.
[0034] One end of the first drill bit 3 for expanding the hole diameter is surrounded by three rotary blades 31 . The width of the rotary blades 31 extends radially along the first drill bit 3 , and the length of the rotary blades 31 extends spirally along the axial direction of the first drill bit 3 .
[0035] The diameter of the virtual cylinder formed by the three rotary blades 31 is smaller than the diameter of the first drill bit 3 , and the central axes are the same.
[0036] It should be noted that the top surface of the virtual cylinder formed by the three rotary blades 31 decreases in height from the center radially toward the edge, forming a cone shape, so as to better expand the hole.
[0037] The end surface of the first drill bit 3 on which the rotary blade 31 is provided is formed with an inclined surrounding step 32 for forming an annular groove on the outer end surface of the enlarged air release hole and the oil release hole.
[0038] It should be noted that when the expanded air vent hole and the oil vent hole are threadedly connected to the connector 2, the sealing gasket is placed in 23 to achieve a better sealing effect.
[0039] The cross section of the bottom surface of the second drill bit 4 adjacent to one end of the side wall provided with threads is in the shape of a cross, and the cross section of the bottom surface of the other end is in the shape of a square.
[0040] It should be noted that the bottom surface with a "cross"-shaped cross section can maintain the stability of the second drill bit 4 when the second drill bit 4 is tapping, making it less likely to deform and be damaged. The other bottom surface with a square cross section can enable the second drill bit 4 to be tightly connected to other tools such as an electric hammer for stable operation.
[0041] Embodiment 2:
[0042] The utility model mainly comprises: a discharge valve 1 and a connecting piece 2 screwed to the tail end of the discharge valve 1, and also comprises a first drill bit 3 for enlarging the diameter of an original air release hole and an oil release hole and a second drill bit 4 for tapping the enlarged air release hole and the oil release hole. The diameter of one end of the first drill bit 3 for enlarging the hole diameter is equal to the diameter of one end of the second drill bit 4 for tapping. The end of the second drill bit 4 for tapping and the end of the connecting piece 2 away from the discharge valve 1 are provided with threads with equal diameters and densities, so that the connecting piece 2 is screwed to the tapped screw hole of the second drill bit 4.
[0043] It should be noted that tapping is a metalworking process that involves using a specific tool, such as a tapping plate or a tap, to rotate and press on the surface of a metal material to form an external thread. This process is also known as thread tapping, which is a processing method used to cut threads on a workpiece, commonly used in the manufacture of mechanical parts and molds and other products.
[0044] The connecting member 2 has a nut 21 at one end for threading the discharge valve 1 , and a screw rod 22 at the other end. The nut 21 and the screw rod 22 are coaxially arranged.
[0045] The end surface of the screw rod 22 away from the nut 21 is provided with a sealing head 24 , and the center of the free end of the sealing head 24 is provided with a second through hole 240 penetrating the central axis.
[0046] It should be noted that the free end of the sealing head 24 is in the shape of a cone with a pointed center, and the sealing head 24 plays a sealing role.
[0047] One end of the first drill bit 3 for expanding the hole diameter is surrounded by three rotary blades 31 . The width of the rotary blades 31 extends radially along the first drill bit 3 , and the length of the rotary blades 31 extends spirally along the axial direction of the first drill bit 3 .
[0048] The diameter of the virtual cylinder formed by the three rotary blades 31 is smaller than the diameter of the first drill bit 3 , and the central axes are the same.
[0049] It should be noted that the top surface of the virtual cylinder formed by the three rotary blades 31 decreases in height from the center radially toward the edge, forming a cone shape, so as to better expand the hole.
[0050] The end surface of the first drill bit 3 on which the rotary blade 31 is provided is formed with an inclined surrounding step 32 for forming an annular groove on the outer end surface of the enlarged air release hole and the oil release hole.
[0051] It should be noted that the groove can make the connector 2 screw deeper when it is screwed, so that the sealing head 24 fits better with the air release hole and the oil release hole, thereby achieving a better sealing effect.
[0052] The cross section of the bottom surface of the second drill bit 4 adjacent to one end of the side wall provided with threads is in the shape of a cross, and the cross section of the bottom surface of the other end is in the shape of a square.
[0053] It should be noted that the bottom surface with a "cross"-shaped cross section can maintain the stability of the second drill bit 4 when the second drill bit 4 is tapping, making it less likely to deform and be damaged. The other bottom surface with a square cross section can enable the second drill bit 4 to be tightly connected to other tools such as an electric hammer for stable operation.
[0054] In this specification, each embodiment is described in parallel, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.
