In order to achieve the above purpose, the utility model adopts the technical scheme that: a screw shaft drilling die comprises a base, a jacking block and a bolt, wherein one end of the base is provided with a drill jig, the other end of the base is provided with a locking seat, the drill jig is provided with an axial positioning sleeve and a drill hole, and the locking seat is provided with a screw knob; one end of the screw shaft penetrates through the axial positioning sleeve and enters the drill jig, the other end of the screw shaft is matched with the jacking block, a long hole structure is arranged on the screw shaft, the length direction of the long hole is parallel to the axial direction of the screw shaft, the width of the inserted rod of the inserted pin is equal to that of the long hole, and the inserted rod of the inserted pin penetrates through the long hole and is inserted into the base; the screw shaft is provided with a shaft shoulder structure, and the jacking block pushes the screw shaft to move along the axial direction of the screw shaft by screwing the screw knob, so that the shaft shoulder of the screw shaft jacks the axial positioning sleeve.
Preferably, the cross section of the jacking block is of an L-shaped structure and comprises a vertical part and a horizontal part, the screw knob jacks the rear side of the vertical part, and the front side of the vertical part is attached to the end face of the screw shaft; the bottom surface of the horizontal part is attached to the upper surface of the base, and the upper surface of the horizontal part is provided with an arc-shaped groove which is matched with the outer circumference of the end part of the screw shaft.
Because of above-mentioned technical scheme's application, compared with the prior art, the utility model have the following advantage:
according to the screw shaft drilling die, the screw shaft is inserted into the drill jig along the axial positioning sleeve, the bolt is inserted, and the screw knob is screwed, so that clamping can be completed; the screw shaft machining device is simple in overall structure, low in cost and convenient to operate, machining efficiency is improved, and the outer circumferential surface of the screw shaft cannot be damaged.
Drawings
The technical scheme of the utility model is further explained by combining the attached drawings as follows:
fig. 1 is a schematic structural view of a screw shaft drilling die of the present invention;
fig. 2 is a sectional view a-a of fig. 1.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in figures 1-2, a spiral shell axle drilling mould for 8 bores the pinhole that the screw propeller moves back of spiral shell axle, the mould contains base 1, puller block 2 and bolt 3, the one end of base 1 is provided with jig 4, the other end is provided with locking seat 5, be provided with axial positioning cover 6 and drilling on the jig 4, be provided with screw rod knob 7 on the locking seat 5.
During installation, one end of the screw shaft 8 penetrates through the axial positioning sleeve 6 and enters the drill jig 4, the axial positioning sleeve 6 is tightly matched with the main body part of the screw shaft 8 to play an axial positioning role for the screw shaft 8, and a drill hole in the drill jig 4 corresponds to the position of a pin hole withdrawal prevention drill hole of the screw shaft 8.
The other end of the screw shaft 8 is matched with the jacking block 2, the cross section of the jacking block 2 is of an L-shaped structure and comprises a vertical part and a horizontal part, the screw knob 7 jacks the rear side of the vertical part, and the front side of the vertical part is attached to the end face of the screw shaft 8; the bottom surface of the horizontal part is attached to the upper surface of the base 1, and the upper surface of the horizontal part is provided with an arc-shaped groove which is matched with the outer circumference of the end part of the screw shaft 8; the structure enables one part of the end part of the screw shaft 8 to be embedded into the jacking block 2, and prevents the jacking block 2 from deviating in the jacking process.
The screw shaft 8 is provided with a long hole structure, the length direction of the long hole is parallel to the axial direction of the screw shaft 8, the width of an inserted rod of the bolt 3 is equal to that of the long hole, and the inserted rod of the bolt 3 penetrates through the long hole to be inserted into the base 1; the inserted bar of bolt 3 can be divided into two sections, and the hypomere is the round bar, is convenient for insert the slot hole and the base 1 of spiral shell axle 8, and the upper segment is the square pole, can further guarantee that spiral shell axle 8 is stable, round bar portion and square bar portion smooth transition.
