Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is made concrete introduction.

Referring to Figures 1, 2, 3, 4 and 5, an on-site processing adjustable boring tool holder of the present invention includes a boring bar 1, a cutter head 2, a tool holder 6 and a horseshoe-shaped holder holder 3, and the cutter head 2 are set on the boring bar 1, and the horseshoe-shaped tool holder holder 3 is fixed on one side of the cutter head 2. The distance between the two side walls of the horseshoe-shaped tool rest holder 3 corresponds to the diameter of the boring bar 1 .

Both side walls of the cutter head 2 are provided with a plurality of positioning grooves 2.1, and both sides of the horseshoe-shaped tool rest holder 3 are provided with a plurality of installation through holes 3.1, and the installation through holes 3.1 and the positioning grooves 2.1 are fixedly connected by fixing bolts 4 , so that the horseshoe-shaped knife rest holder 3 and the knife head 2 are fixedly connected together. There are two horseshoe-shaped knife rest holders 3, which are respectively fixed on both sides of the cutterhead 2, and can respectively complete the turning of the left and right sides, and can realize the feeding of the left and right directions during boring. When the machining allowance is large, the horseshoe-shaped tool holder fixing seat 3 can be reinstalled by adjusting the installation position of the fixing bolt 4, so that a larger range of radial feed can be realized.
