Problems solved by technology

[0002] The boring tool for boring is generally composed of a tool bar and a mounting seat fixed on the head of the tool bar. Due to the high-speed operation of the machine tool, vibration will occur between the workpiece to be processed and the tool mounting structure, which will affect the machining accuracy of the part.
The reason is that on the one hand, the installation stability of the workpiece to be processed is poor, and on the other hand, the installation structure design of the boring tool is not reasonable enough

Embodiment Construction

[0011] see figure 1 :

[0012] The installation structure of the embedded boring tool includes the tool bar 1, the front end of the tool bar 1 is screwed to install a block-shaped tool seat 2, the outer wall of the tool bar 1 is screwed to install a locking sleeve 3, and the front surface of the locking sleeve 3 withstands the tool seat 2. Use the locking sleeve to ensure that the connection between the knife rod and the knife seat 2 is firm, and it is not easily affected by vibration. The lower right corner of the knife seat 2 is inclined at 30° to 60° and cut into a bevel 4. There is a knife extending into the bevel 4 The triangular mounting hole 5 in the seat 2 is embedded with a boring tool 6, which improves the stability and firmness of the boring tool 6 during use after it is installed. The front end of the tool seat 2 has a The locking hole 7 facing the mounting hole 5 is screwed with a locking bolt 8 in the locking hole 7, and the front end of the locking bolt 8 withs...

Abstract

The invention discloses a structure for mounting a boring cutter in an embedding manner. The structure comprises a cutter bar, wherein a block-shaped cutter holder is mounted at the front end of the cutter bar in a screwing manner; a locking sleeve is mounted on the outer wall of the cutter bar in a screwing manner; the front end surface of the locking sleeve is propped against the cutter holder; the lower right corner of the cutter holder is cut into an oblique plane; a triangular installation hole extending into the cutter holder is formed in the oblique plane; the boring cutter is inserted into the installation hole in the embedding manner; a locking hole opposite to the installation hole of the boring cutter is formed in the front end surface of the cutter holder; a locking bolt is screwed in the locking hole; and the front end of the locking bolt is propped against the boring cutter. According to the structure, the structural design is novel; the locking sleeve guarantees the firm connection between the cutter bar and the cutter holder; and the boring cutter is mounted in the cutter holder in an embedding manner, so that the stability is improved, influence caused by vibration can be avoided easily, and the mechanical processing accuracy is greatly improved.

Description

Technical field: [0001] The invention relates to machining, in particular to an embedded boring tool installation structure. Background technique: [0002] The boring tool for boring is generally composed of a tool bar and a mounting seat fixed on the head of the tool bar. Due to the high-speed operation of the machine tool, vibration will occur between the workpiece to be processed and the tool mounting structure, which will affect the machining accuracy of the part. The reason is that on the one hand, the installation stability of the workpiece to be processed is poor, and on the other hand, the installation structure design of the boring tool is not reasonable enough. [0003] In view of the above problems, the installation stability of the workpiece to be processed is relatively easy to solve, and the installation structure of the boring tool is the most urgent problem to be solved in terms of mechanical precision. Invention content: [0004] In order to make up for t...
