Embodiment 1

[0045] As a basic embodiment of the present invention, the present invention includes an alignment tool for machining a part with a closed angle. A reference hole 1 is machined on the part, and the alignment tool 3 includes a locking piece and a Spherical alignment piece 4 , conical limiting piece 5 , cylindrical positioning piece 6 . The spherical alignment element 4 is used for alignment center. The other end of the cylindrical positioning member 6 is used to be inserted into the reference hole 1 to cooperate with the locking member to fix the alignment tool 3 . The locking member is a locking nut 7, and the outer wall of the cylindrical positioning member 6 is provided with a thread 9 matching the nut. A plastic ring 8 is provided on the side of the locking nut 7 close to the conical limiting member 5 .

Embodiment 2

[0047] As a preferred embodiment of the present invention, refer to the accompanying figure 1 , the present invention includes a closed-angle part processing method, which utilizes the alignment tool 3 in the first embodiment. The processing method includes:

[0048] a. Find the reference hole 1 that has been machined in the previous operation on the part.

[0049] b. Determine the outer diameter Φ of the cylindrical positioning member 6 according to the diameter of the reference hole 1, define the distance L between the end face of the conical limiting member 5 away from the spherical alignment member 4 and the center of the spherical alignment member 4, and find the Positive tool 3.

[0050] c. Insert the cylindrical positioning member 6 in the alignment tool 3 into the reference hole 1, and use the cooperation of the locking nut 7 and the thread 9 to lock the part and the alignment tool 3.

[0051] d. Use a feeler gauge to detect the gap between the alignment tool 3 and ...

Embodiment 3

[0056] As the best mode for carrying out the present invention, refer to the appendix of the specification. figure 1 , the present invention includes an alignment tool for machining parts with a closed angle, a reference hole 1 is processed on the part, and the alignment tool 3 includes a locking piece and a spherical alignment piece 4, which are coaxially connected in turn. Conical limiting member 5, cylindrical positioning member 6. The end of the conical limiting member 5 connected with the spherical aligning member 4 is provided with an inwardly concave groove that matches the spherical aligning member 4, so as to facilitate better connection with the spherical aligning member 4 and ensure that the The requirement of coaxiality reduces the cumulative error, and does not affect the position of the contact point of the watch needle when confirming the center of the spherical alignment member 4 .

[0057] The other end of the cylindrical positioning member 6 is used to be in...

Abstract

The invention relates to the technical field of numerical control machining, and particularly relates to an alignment tool for machining for a part with a closed angle, and a machining method. The alignment tool comprises a locking element, as well as a spherical alignment element, a conical limiting element and a cylindrical locating element which are coaxially connected in sequence. By means ofthe alignment tool, the problem that the closed angle cannot be aligned is solved. According to the machining method for the part with the closed angle, the alignment tool is used, and when a to-be-machined hole of the part is machined, a three-axis numerical control machine tool can be used for accurate alignment, so that the production cost is greatly saved, the production efficiency is increased, and the product quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of numerical control machining, in particular to an alignment tool and a machining method for machining parts with closed angles. Background technique [0002] In the CNC milling of aerospace structural parts, often because the opening and closing angles of the parts are too large, the rotation angle and rotation accuracy of the CNC machine tools are required to be high, resulting in a substantial increase in production costs. There are the following problems in the processing process: [0003] (1) When the part has a closed angle θ, and the reference hole has been processed in the previous process, this process requires the processing of the to-be-machined hole, and there is a closed angle θ between the planes where the to-be-machined hole and the reference hole are located. Since the design of the part requires ensuring the position of the reference hole and the hole to be processed, when using a precision...
