Detailed Description
As shown in fig. 2, fig. 2 is a schematic structural view of a high-strength shock-absorbing tool bar according to the present invention.
Referring to fig. 2, the present invention provides a high strength shock-absorbing cutter bar, including: the mounting seat 5, the rod body 4, the top seat 2 and the blade 1;
4 one ends of the rod body are fixed on the mounting seat 5 and the other end is equipped with the connecting piece 3, the footstock 2 is located the rod body 4 and keeps away from 5 one side of the mounting seat and 2 one ends of the footstock pass through the connecting piece 3 and the rod body 4 fixed connection, the thickness of the footstock 2 is gradually increased towards the direction close to the connecting piece 3, the interval is preset between the footstock 2 and the rod body 4 and is separated from the two to form a containing gap, and the blade 1 is located and is installed at the footstock 2 and keeps away from 3 one end of the connecting piece and is located.
In specific structural design, mount pad 5, the body of rod 4, connecting piece 3 and 2 integrative bodys of footstock for the footstock thickening can not lead to the fact the influence to the processing complexity.
In the specific processing process of the high-strength shock-absorbing cutter bar of the embodiment on the brake disc, the end part of the brake disc is inserted into an accommodating gap between the top seat and the rod body, the mounting surface of the brake disc faces the blade, and the blade is driven to rotate by the rod body during processing so as to realize turning of the mounting surface of the brake disc; through bodiness cutter arbor top, improved the cutter arbor rigidity, solved the cutter arbor circumstances of shaking a little in the high-speed processing of product, the tool mark that the product appears and the line of shaking in the actual processing obviously improve, and the steady blade wearing and tearing of processing are little during high-speed cutting simultaneously, improve the blade life-span, reduction in production cost improves product quality, has promoted the product percent of pass greatly.
