Description

Technical Field

[0001] This invention relates to the field of CNC machining technology, and is an auxiliary device and method for ensuring accurate and rapid installation of cutting tools onto the angle head. It can be widely used in the installation operation of "angle head" cutting tools in mechanical processing in equipment manufacturing and other fields. Background Technology

[0002] In the field of equipment manufacturing, especially in the machining of complex structures such as lug holes, semi-enclosed cavities, vertical sealing grooves, and aero-engine casings for aviation parts, "angle heads" are a common CNC machine tool accessory with a high frequency of application.

[0003] The following problems exist:

[0004] 1. The installation length of the angle head tool has a significant impact on the machining quality. Any installation error will lead to product quality problems.

[0005] 2. The tool lacks axial positioning during installation, making it impossible to precisely control the tool installation length, and the installation and calibration process consumes a lot of time. Summary of the Invention

[0006] The purpose of this invention is to provide an auxiliary device and method for ensuring accurate and rapid installation of cutting tools onto an angle head (as shown in the attached diagram). Figure 2 Its advantages lie in accurate tool loading and simple operation.

[0007] According to one aspect of this application, an auxiliary device is provided to ensure accurate and rapid installation of a cutting tool onto an angle head, comprising a base 1, a fixing bolt 2, a fixing nut 3, a fixing handle 4, a connecting bolt 5, a connecting nut 6, a washer 7, a support frame 8, a positioning block 9, a positioning pin 10, an auxiliary clamping block 11, a cutting tool clamping plate 12, a clamping bolt 13, a clamping nut 14, and a clamping washer 15.

[0008] The base 1 serves as the mounting base and is connected to the desktop or workbench by fixing bolts 2 and fixing nuts 3, and is fixed by tightening the threads with fixing handle 4.

[0009] The support frame 8 is connected to the base 1 via four connecting bolts 5, four connecting nuts 6, and four washers 7, which are machined into four bolt holes.

[0010] The positioning block 9 is positioned and connected to the support frame 8 by two positioning pins 10.

[0011] The tool pressure plate 12 is connected to the bolt holes machined on the positioning block 9 via the clamping bolts 13, clamping nuts 14, and clamping washers 15.

[0012] The auxiliary clamping block 11 plays an auxiliary clamping role, which can make the tool clamping action more secure.

[0013] The base 1 is provided with two positioning holes, a large hole and a small hole;

[0014] The diameter d1 of the large hole in the base 1 is consistent with the outer diameter of the spindle interface of the angle head used.

[0015] The diameter d2 of the small hole in the base 1 is consistent with the outer diameter of the locating pin of the angle head used.

[0016] The distance L1 between the two positioning holes of the base 1 is consistent with the distance between the spindle interface and the positioning pin of the angle head used.

[0017] In the auxiliary device, L = L2 + L3 - L4 is satisfied;

[0018] Where L is the length of the tool to be installed;

[0019] L2 is the distance from the center line of the large hole of the base 1 to the contact surface of the support frame 8;

[0020] L3 is the distance from the center line of the positioning pin 10 to the contact surface of the support frame 8;

[0021] L4 is the distance from the center line of the positioning pin 10 to the facade of the positioning block 9.

[0022] The sum of the thickness δ of the positioning block 9, the radius R of the tool to be installed, and the height h2 of the support frame 8, minus the distance h1 from the horizontal positioning surface of the large hole on the base 1 to the contact plane of the support frame 8, should be consistent with the height h of the tool axis of the angle head used, i.e., h = δ + R + h2 - h1.

[0023] In the auxiliary device, h = δ + R + h2 - h1 is satisfied;

[0024] Where h is the axial height of the tool to be installed;

[0025] δ is the thickness of the positioning block 9;

[0026] R is the radius of the tool to be installed;

[0027] h1 is the distance between the horizontal positioning surface of the large hole on the base 1 and the contact plane of the support frame 8;

[0028] h2 is the height of support frame 8.

[0029] The installation of cutters of different lengths and radii on the same type of angle head is achieved by adjusting the thickness δ of the positioning block 9 and the distance L4 between the center line of the positioning pin 10 and the vertical surface of the positioning block.

[0030] The base 1 is positioned with the angle head of the tool to be installed through a large hole, a small hole and the upper surface of the large hole, so that the end face of the angle head of the tool to be installed and the tool holder axis have a definite position and a definite positional relationship with the base 1.

[0031] The support frame 8 is connected to the base 1, transmitting the positioning reference and providing an installation plane for the positioning block 9;

[0032] The positioning block 9 transfers the positioning reference to its plane and elevation again through two positioning pins 10. The elevation is the tool axial positioning reference, and the plane is the tool radial positioning reference.

[0033] The tool is clamped by the tool clamping plate 12, clamping bolt 13, clamping nut 14, and clamping washer 15 to facilitate the tightening of the angle head tool clamp, and the auxiliary clamping block 11 makes the above-mentioned tool clamping action more secure.

[0034] According to another aspect of this application, a method for accurately and quickly installing a cutting tool onto an angle head is provided, employing the aforementioned auxiliary device for ensuring accurate and quick installation of the cutting tool onto the angle head;

[0035] Includes the following steps:

[0036] Step S1: Install and fix the auxiliary device on the workbench using fixing bolts 2;

[0037] Step S2: Install the milling cutter 19 onto the angle head 18, so that the tool holder 1803 is in a relaxed state;

[0038] Step S3: Install the main shaft fixing end face 1801 and the positioning pin block 1802 of the angle head 18 into the large hole and small hole of the auxiliary device, so that it has a fixed spatial position;

[0039] Step S4: Make the milling cutter 19 contact the plane and the vertical surface of the positioning block 9 respectively, so that the milling cutter 19 has a defined spatial position;

[0040] Step S5: Tighten the clamping nut 14 to fix the spatial position of the milling cutter 19, and make sure that the pressure plate avoids the cutting edge of the milling cutter;

[0041] Step S6: Tighten the tool holder 1803 to complete the installation of the angle head tool.
