Description

Technical Field

[0001] The utility model belongs to the technical field of five - way universal fixtures, and particularly relates to a numerical control lathe fixture for five - way pipe joints. Background Technique

[0002] Conventionally used pipe joints are generally straight - through, 90° right - angle, three - way, four - way, etc. For the machining of five - way pipe joints used in aero - engines, for example, when using a numerical control lathe for machining, repetitive alignment of the five - way is required. However, the five - way has large angle changes, difficult repeated positioning, and long time consumption, resulting in low machining efficiency of the five - way. Content of the Utility Model

[0003] In view of this, the numerical control lathe fixture for five - way pipe joints provided by the utility model improves the machining efficiency of the five - way on the numerical control lathe.

[0004] A numerical control lathe fixture for five - way pipe joints, suitable for the machining of a numerical control lathe, includes a body and a first clamping portion and a second clamping portion spaced apart on the body. Among them,

[0005] Both the first clamping portion and the second clamping portion are arranged on the body in an inclined manner, and the first clamping portion and the second clamping portion clamp the five - way in a detachable manner.

[0006] Preferably, the included angle between the five - way after being clamped and the Z - axis of the numerical control lathe is 100°.

[0007] Preferably, the first clamping portion and the second clamping portion are parallel to each other.

[0008] Preferably, both the first clamping portion and the second clamping portion and the body are arranged in an integral structure.

[0009] Preferably, rounded corners are formed at the connection positions between the first clamping portion and the second clamping portion and the body.

[0010] Preferably, the outer side surface of the body away from the first clamping portion and the second clamping portion is arranged in a straight - plane structure.

[0011] Preferably, the inner side surface of the body between the first clamping portion and the second clamping portion is arranged in an inclined - plane structure, or the inner side surface of the body between the first clamping portion and the second clamping portion is parallel to the axis of the five - way.

[0012] Preferably, a pin hole is formed on the first clamping portion, and a pin is inserted into the pin hole. The pin is used for fixing one axial end of the five - way;

[0013] A threaded hole is formed at a position corresponding to the pin hole on the second clamping portion, and a bolt assembly is installed in the threaded hole. The bolt assembly is used for fixing the other axial end of the five - way. Among them,

[0014] When the first clamping part and the second clamping part clamp the five-way joint, one axial end of the five-way joint contacts the bottom surface of the first clamping part, and the other axial end of the five-way joint contacts the top surface of the second clamping part.

[0015] Preferably, mounting holes are respectively formed at both ends of the body, and the mounting holes are used for mounting the body on a numerical control lathe.

[0016] Preferably, a weight-reducing hole is formed on the body between the mounting holes.

[0017] Advantageous Effects

[0018] Both the first clamping part and the second clamping part are arranged on the body in an inclined manner. When the first clamping part and the second clamping part are used for quickly clamping the five-way joint, it is not necessary to align the five-way joint, and it can be directly processed, thereby improving the processing efficiency of the five-way joint by a numerical control machine tool.

[0029] As Figures 1 to 3 shown, the five-way pipe joint number lathe fixture is applicable to the processing of the five-way by a numerical control lathe. The five-way 6 is shown in Figure 2 shown. It includes a body 1 and a first clamping portion 2 and a second clamping portion 3 spaced apart on the body 1. The body 1, preferably, is arranged in a flat plate-like structure, such as a quadrilateral structure. Among them,

[0030] Both the first clamping portion 2 and the second clamping portion 3 are arranged on the body 1 in an inclined manner. The first clamping portion 2 and the second clamping portion 3 clamp the five-way 6 in a detachable manner. Specifically,

[0031] The first clamping part 2 and the second clamping part 3 are parallel to each other. Preferably, they are arranged in a flat plate-like structure. The inclination angle of the first clamping part 2 and the second clamping part 3 is such that after the five-way joint 6 is clamped, the included angle with the Z-axis of the CNC lathe is 100°, realizing the rapid alignment of the machining position of the five-way joint 6.

[0032] As a specific implementation manner provided in this case, the first clamping part 2, the second clamping part 3 and the body 1 are all arranged in an integral structure, which is convenient for the manufacture of the overall fixture. Preferably, rounded corners are formed at the connection positions of the first clamping part 2, the second clamping part 3 and the body 1 to avoid excessive stress concentration during the use of the fixture, extend the service life of the fixture, and prevent the fixture from being damaged due to stress concentration during the use process.

[0033] As a specific implementation manner provided in this case, the outer side surface of the body 1 away from the first clamping part 2 and the second clamping part 3 is arranged in a straight plane structure. Preferably, the inner side surface of the body 1 between the first clamping part 2 and the second clamping part 3 is arranged in an inclined plane structure, or the inner side surface of the body 1 between the first clamping part 2 and the second clamping part 3 is parallel to the axis of the five-way joint 6. When the CNC lathe processes the five-way joint 6, it is avoided that the end of the five-way joint 6 contacts the body 1, ensuring the machining quality of the five-way joint 6.

[0034] As a specific implementation manner provided in this case, a pin hole 21 is opened on the first clamping part 2, and a pin 22 is inserted into the pin hole 21. The pin 22 is used for fixing one axial end of the five-way joint 6. A threaded hole 31 or a bolt hole is opened at the corresponding position on the second clamping part 3. A bolt assembly is installed in the threaded hole 31. The bolt assembly is used for fixing the other axial end of the five-way joint 6. Among them,

[0035] When the first clamping part 2 and the second clamping part 3 clamp the five-way joint 6, one axial end of the five-way joint 6 contacts the bottom surface of the first clamping part 2, and the other axial end of the five-way joint 6 contacts the top surface of the second clamping part 3. The bolt assembly, for example, includes a lock nut and a bolt. During use, first install a positioning pin or a pin 22 in the pin hole 21. One end of the positioning pin or the pin 22 extends into one axial end of the five-way joint 6 to initially fix the five-way joint 6. At this time, the other end of the five-way joint 6 contacts the top surface of the second clamping part 3 and is directly opposite to the threaded hole 31 or the bolt hole. Install the bolt to fix the other end of the five-way joint 6, and then rotate the lock nut to tighten the five-way joint 6. After the five-way joint 6 is firmly clamped, install the body 1 on the machining table of the CNC machine tool to process the five-way joint 6 without aligning the five-way joint 6, thereby improving the machining efficiency of the five-way joint 6.

[0036] As a specific implementation manner provided in this case, mounting holes 4 are respectively opened at both ends of the body 1. The mounting holes 4 are used for mounting the body 1 on the CNC lathe. And, a weight-reducing hole 5 is opened on the body 1 between the mounting holes 4.

[0037] As described above, this is only a specific implementation of the present disclosure. However, the protection scope of the present disclosure is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed by the present disclosure should be covered within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure shall be subject to the protection scope of the claims.
