Further, the setting element includes deciding dabber, position sleeve and gland, decide the dabber and fix on the disc, just decide the dabber coaxial with the disc, the suit can be dismantled on deciding the dabber to the position sleeve, the gland can be dismantled with deciding the dabber and can carry out spacingly to the position sleeve after being connected. The positioning sleeve can be designed into various specifications, and the positioning sleeve is replaced through the detachable connection of the fixed core shaft and the positioning sleeve, so that the scheme can be suitable for impellers of positioning inner holes of various specifications, and the shape changing operation is convenient; the gland can effectively place the position sleeve and produce the ascending removal of axial, guarantees the stable connection of position sleeve and fixed dabber.

Furthermore, the slide rails are fixed around the disc in pairs at equal intervals in the circumferential direction, and one slide block is connected to the two slide rails in pairs in a sliding manner. A slider sliding connection is on two slide rails for the slider is more stable, guarantees the machining precision, and slide rail axial equidistance is fixed on the disc, can guarantee the machining precision.

Furthermore, a pressing plate is further arranged on the sliding block and fixed on the sliding block through bolts. The clamp plate can be placed at the impeller and fixed the impeller after on the anchor clamps body, avoids the impeller to produce not hard up or axial removal in the in-process of processing to influence the problem of machining precision.

Further, still include the outer lane, the outer lane is fixed at the slide rail tip. The slide rail is strengthened and fixed through the outer ring, and the stability of the slide rail is guaranteed.

Further, still include the lead screw and can restrict lead screw pivoted retaining member, the lead screw is located between two mated slide rails, the lead screw pass the slider and with slider threaded connection, the retaining member is fixed on the periphery, lead screw one end is rotated and is connected on the disc, the lead screw other end is connected with the retaining member. The lead screw can rotate when the slider slides, and after the slider was fixed, messenger's retaining member locking lead screw restricted the rotation of lead screw, and the lead screw lock is died and can be fixed a position the slider once more, avoids the slider to slide, guarantees the machining precision.

Further, the slider is equipped with four, the slide rail is equipped with four pairs. The scheme is a specific selection of the technical scheme.

Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: the device comprises a disc 1, a positioning piece 2, a sliding rail 3, a sliding block 4, a locking nut 5, a fixed core shaft 6, a positioning sleeve 7, a gland 8, a pressing plate 9, a bolt 10, an outer ring 11, a screw rod 12 and a locking piece 13.

Example one

Substantially as shown in figure 1: the utility model provides an adjustable turning instrument of semi-open ternary flow impeller, including the anchor clamps body, slider 4 and lock nut 5, the anchor clamps body includes disc 1, slide rail 3 on disc 1 is fixed to circumference, fix at setting element 2 and outer lane 11 at disc 1 center, it is shown in the combination figure 2, setting element 2 is including deciding dabber 6, position sleeve 7 and gland 8, decide dabber 6 welding on disc 1, and decide dabber 6 coaxial with disc 1, the suit can be dismantled on deciding dabber 6 to the position sleeve 7, gland 8 can be dismantled with deciding dabber 6 and be connected the back and carry on spacingly to position sleeve 7. The slide rail 3 is equipped with eight, and eight slide rail 3 become four pairs of circumference equidistance welding around disc 1, and the welding of outer lane 11 is at the tip of eight slide rail 3, and a slider 4 sliding connection is on two mated slide rail 3.
