Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of milling head workpieces, in particular to a milling head processing tool. Background Art
[0002] The milling head workpiece is an important machine tool accessory installed on a CNC milling machine and connected to the spindle. It is used to drive the milling cutter to rotate to achieve various processing operations and expand the scope of use and functions of the machine tool.
[0003] The spindle of the milling head workpiece can rotate within two mutually perpendicular rotating planes, and can complete a variety of tasks such as vertical milling and flat milling. At the same time, it allows multi-angle, multi-faceted, multi-edge and multi-groove milling in one clamping of the workpiece.
[0004] During the processing of the milling head workpiece, the CNC lathe is used to process the workpiece, such as milling. Therefore, during processing, the workpiece needs to be positioned and locked on the fixture. However, due to the complex shape of the milling head workpiece, its main structure includes an axial structure, a connecting structure perpendicular to the axial structure, etc. This causes the workpiece structure to have a large degree of irregularity, making it difficult to position. Therefore, it cannot be positioned by ordinary fixtures. For example, the screw and pressure plate positioning structures used in ordinary fixture positioning can position the workpiece, but the stability is not high, which is reflected in the milling process, and the workpiece is easy to be thrown.
[0005] Therefore, in the actual production process, it is necessary to design a positioning fixture with high positioning stability, convenient and efficient operation, and quick installation and removal according to its shape and size, thereby greatly improving the production and processing efficiency.

The specific method is: rotate the first locking plate, the second locking plate and the third locking plate until the arc-shaped pressure openings on the first locking plate, the second locking plate and the third locking plate press the shaft-shaped part on the milling head workpiece.

[0038] Example 1
[0039] like Figure 1-4 As shown, a milling head processing tool includes a tooling table 5. According to the conventional method, a tooling base plate 4 is assembled and connected on the top of the tooling table 5, and a locking mechanism for locking the milling head workpiece is assembled and connected on the top of the tooling base plate 4. The locking mechanism is used to position the milling head workpiece 10 with a relatively complex special-shaped structure.
[0040] Its specific structure is as follows:
[0041] The locking mechanism includes a loading assembly fixedly connected to the tooling base plate 4, and the milling head workpiece 10 is loaded on the loading assembly; the locking mechanism also includes a locking assembly for locking the milling head workpiece 10, and the locking assembly includes a plurality of fixed baffles fixedly connected to the tooling base plate 4, and the fixed baffles abut against the side of the milling head workpiece 10.
[0042] Specifically, the locking and pressing assembly includes a first fixed baffle, a second fixed baffle and a third fixed baffle 7 fixedly connected to the tooling bottom plate 4; the first fixed baffle, the second fixed baffle and the third fixed baffle 7 are arranged in a transverse arrangement. The first fixed baffle, the second fixed baffle and the third fixed baffle 7 are arranged at the top front side of the tooling bottom plate 4. Specifically, they are fixed to the tooling bottom plate 4 by welding.
[0043] The upper ends of the first fixed baffle plate, the second fixed baffle plate and the third fixed baffle plate 7 are respectively hinged with locking plates, specifically, the first fixed baffle plate, the second fixed baffle plate and the third fixed baffle plate 7 are respectively hinged with the first locking plate, the second locking plate and the third locking plate (distributed from the left to the right). The hinged manner is: the upper ends of the first fixed baffle plate, the second fixed baffle plate and the third fixed baffle plate 7 are respectively hinged with hinge plates 71 through pin shafts, and the hinge plates 71 are fixedly connected to the corresponding first locking plate 3, the second locking plate 2 and the third locking plate 1.
[0044] At the same time, the first locking plate 3, the second locking plate 2 and the third locking plate 1 are all provided with arc-shaped pressing openings, and the milling head workpiece 10 is locked in the arc-shaped pressing openings. The size and curvature of the arc-shaped pressing openings are designed to be different according to the different parts of the first locking plate 3, the second locking plate 2 and the third locking plate 1 that are locked on the workpiece.
[0045] The locking plate is threadedly connected with a locking screw 8. When the locking plate locks the milling head workpiece 10, the locking screw 8 is locked on the fixed baffle. Specifically, the locking screw 8 is located outside the arc-shaped pressure port, and the top rear sides of the first fixed baffle, the second fixed baffle, and the third fixed baffle 7 are respectively provided with thread grooves, and the locking screw 8 is threadedly connected in the thread grooves.
[0046] During the operation, the locking screw 8 is threadedly connected to the thread groove. The specific method is: rotate the first locking plate 3, the second locking plate 2 and the third locking plate 1 until the arc-shaped pressure openings on the first locking plate 3, the second locking plate 2 and the third locking plate 1 press the axial portion on the milling head workpiece 10. Because the size and shape of the arc-shaped pressure openings on the first locking plate 3, the second locking plate 2 and the third locking plate 1 correspond to the workpiece, the workpiece can be fully locked from three different positions in this way.
[0047] This method not only has high locking stability, but is also very convenient to operate.
[0048] At the same time, the above-mentioned locking plate is threadedly connected with a contact pressure screw 9 (the contact pressure screw 9 is located in the arc-shaped pressure port) for contacting and pressing the milling head workpiece 10. Specifically, the contact pressure screws 9 on the first locking plate 3 and the third locking plate 1 are tilted and arranged inward; the contact pressure screw 9 on the second locking plate 2 is arranged vertically. During operation, the contact pressure screws 9 on the first locking plate 3 and the third locking plate 1 are tilted in the direction to press the milling head workpiece 10 tightly, and at the same time, the contact pressure screw 9 on the second locking plate 2 presses the milling head workpiece 10 vertically from top to bottom. In this way, the locking of the milling head workpiece 10 is further improved.
[0049] Example 2
[0050] like Figure 1-4 As shown, based on the structure of Example 1, the carrier assembly 6 includes a Class I carrier plate 61 spaced apart on the left and right sides (the Class I carrier plate 61 is arranged in a left-right direction); the carrier assembly 6 also includes a Class II carrier plate 62 arranged in a triangular position with the Class I carrier plate 61 (the Class II carrier plate 62 is arranged in a front-to-back direction).
[0051] The above-mentioned type I material loading plate 61 and type II material loading plate 62 are respectively provided with arc-shaped material loading openings, and the milling head workpiece 10 is limitedly supported in the arc-shaped material loading openings.
[0052] The above-mentioned type I material carrier plate 61 and type II material carrier plate 62 are fastened to the tooling bottom plate 4 by bolts respectively.
[0053] During operation, the milling head workpiece 10 is placed on the arc-shaped loading openings on the type I loading plate 61 and the type II loading plate 62, and the workpiece is locked in the above-mentioned manner.
[0054] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
