Screw is connect with the second blade mounting base, the utility model scientific structure, utilizes the first boring cutter of knife bar different location,
Two boring cutters are simultaneously processed two kingpin bores, improve production efficiency.
Description of the drawings
Fig. 1 is the schematic diagram of the double-blade boring cutter structure for being used for while processing two kingpin bores of knuckle of the utility model.
Reference sign：
1 --- knife bar 2 --- first blade mounting base
3 --- the first boring cutter 4 --- second blade mounting bases
5 --- the second boring cutter 6 --- alignment pins
7 --- the first groove 8 --- second grooves
9 --- third blade 10 --- third blade mounting bases.
Specific implementation mode
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, is not this practicality
Novel practical range limited to this.
As shown in Figure 1, the double-blade boring cutter being used for while processing two kingpin bores of knuckle of the present embodiment comprising knife bar
1, the front end of the knife bar 1 is provided with the first blade mounting base 2, the first boring cutter 3, and the middle part of the knife bar 1 is provided with the second knife
Sword mounting base 4, the second boring cutter 5, the first blade mounting base 2, the second blade mounting base 4 pass through alignment pin 6 and institute respectively
The connection of knife bar 1 is stated, first boring cutter 3 is connect by fastening screw with the first blade mounting base 2, second boring cutter 5
It is connect with the second blade mounting base 4 by fastening screw.Knife bar 1 is passed through one when use by the utility model scientific structure
Then a kingpin bore starts to process, the first boring cutter 3 one kingpin bore of processing, another kingpin bore of the second boring cutter 5 processing, and first
Boring cutter 3, the second boring cutter 5 one first start to process after one, and preferably the second boring cutter 5 first starts to process, it is only necessary to control the first boring cutter 3,
Which boring cutter the distance between second boring cutter 5, which may be selected, is first processed.In this way, the second boring cutter 5 also plays auxiliary positioning simultaneously
Effect, prevents from causing mismachining tolerance to become larger since knife bar 1 is long.The utility model be greatly shortened processing kingpin bore when
Between, improve production efficiency.
Further, first boring cutter 3 is more than 10cm with the second boring cutter 5 at a distance from 1 axial direction of knife bar.
Further, first boring cutter, 3 and second boring cutter 5 is 170 °~190 ° along the angle of 1 circumferencial direction of knife bar.
Further, the side of the knife bar 1 is provided with the first groove 7, the second groove 8, the first blade mounting base
