Detailed Description
Fig. 1 to 4 are schematic diagrams illustrating a side view structure of a high-strength impact-resistant pressing plate according to the present invention, fig. 2 is a schematic diagram illustrating a top view structure of a high-strength impact-resistant pressing plate according to the present invention, fig. 3 is a schematic diagram illustrating a top view structure of a cutting head assembly according to the present invention, and fig. 4 is a schematic diagram illustrating a partially-fitted cross section of a cutting head assembly according to the present invention.
Referring to fig. 1 and 2, the present invention provides a high-strength impact-resistant press plate, including: a platen body 1;
the middle of the pressing plate body 1 is provided with a vertical through mounting through hole, the bottom of the pressing plate body 1 is provided with a positioning protrusion 11 and a pressing table 12, the positioning protrusion 11 and the pressing table 12 are respectively positioned on two sides of the mounting through hole, and the bottom of the pressing table 12 is provided with a pressing surface and a blade limiting protrusion 13.
Referring to fig. 3 and 4, the present invention also provides a cutting bit assembly including: a mounting seat 2, a cutting insert 3, a tightening bolt 4 and the above-mentioned high-strength impact-resistant pressure plate.
In the specific installation mode of the cutting head component, the installation tool holder 2 is provided with a blade installation position, a bolt installation hole and a positioning groove which are sequentially arranged, the cutting blade 3 is positioned on the blade installation position, the pressing plate body 1 is positioned above the blade, the positioning bulge 11 is matched with the positioning groove, the pressing surface of the pressing table 12 is abutted against the top of the cutting blade 3, the top of the cutting blade 3 is provided with a limiting groove matched with the blade limiting bulge 13, and one end of a fastening bolt 4 penetrates through the installation through hole in the pressing plate body 1 and is in threaded fit with the bolt installation hole in the installation tool holder 2.
In the embodiment, the high-strength impact-resistant pressing plate and the cutting tool bit assembly increase the abrasion loss of the pressing head of the impact pressing plate by increasing the positioning size of the pressing head of the impact pressing plate, prolong the service life of the pressing plate, enable the pressing plate to be worn seriously after the positioning size of the pressing head of the pressing plate is increased, and enable the pressing plate to be replaced in time easily after the pressing plate is worn seriously, and reduce the occurrence of tool explosion when the pressing plate is worn seriously and; in addition, the shape of the optimized pressing plate is provided with a blade limiting bulge at the tail part of the pressing plate, after the cutting tool bit assembly is assembled and the bolt is tightened, the pressing plate generates high-strength pressure on the blade through the blade limiting bulge, and the stability and the reliability of the blade in machining are ensured.
