Detailed description of the invention
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of lobe pump three lobe rotor boring jig as shown in Figure 1, 2, comprises clamp body 3, boring bar 6 that boring cutter 7 is equipped with in the workbench 2 of mounting clamp concrete 3, the end be set up on clamp body 3, and clamp body 3 is rectilinear motion on workbench 2.Boring cutter 7 adopts on fastened by screw boring bar 6, and the position of boring cutter 7 is adjustable.
Clamp body 3 comprises two pieces of thick risers 14 be arranged in parallel, thick riser 14 offers the installing hole installing three lobe rotor spindle nose and the support holes of installing boring bar 6, thick riser 14 being provided with the T-shaped clamping head 4 for being fixed three lobe rotor spindle nose, the clamp body 3 of three lobe rotor both sides being arranged with two radial clamps 5.Radial clamp 5 comprises body and clamping head, clamping head is threaded with body, rotates clamping head, the three lobe rotor that Bidirectional clamping head clamping is to be processed.
Workbench 2 side is provided with fixed head 11, is provided with ball bearing 9 in fixed head 11, is connected with gear train 10 outside ball bearing 9, and inner side is connected with the universal joint 8 be connected with boring bar 6 end.Depth of parallelism when ball bearing 9 ensures that boring bar rotates and positional precision.
Workbench 2 is provided with guide rail rack 1, and clamp body 3 has the gear matched with guide rail rack 1.
Thick riser 14 is that upper and lower two blocks of plates all with semicircle opening are spliced, and two semicircle openings are spliced into installing hole.
T-shaped clamping head 4 lower end is in being convenient to the circular arc clamping three lobe rotor spindle nose, identical with the exradius of three lobe rotor spindle nose.
Thick riser 14 all offers three support holes, the quantity of boring bar 6 and universal joint 8 is three.
Gear train 10 comprises driving gear and three driven gears, and driving gear engages with three driven gears simultaneously.
