Specific embodiment
As shown in Figures 1 to 4, a kind of pump piston slot apparatus, including pedestal 1 and can close to or far from pedestal 1
Head 2, for pedestal 1 for fixed to grooving workpiece, head 2 includes main shaft 21, cutterhead 22 and several slotting tools 23, cutterhead 22 and master
Axis 21 is fixedly connected, and slotting tool 23 includes left folding in 231, knife plate 232 and right folding 233, and left folding is at 231 and right folding 233
It being connect respectively with the two sides of knife plate 232, left folding 233 bottom end in 231, knife plate 232 and right folding is provided with the edge of a knife 234,
To realize that the blade of Qian shape, the edge of a knife 234 are low compared with the bottom surface 221 of cutterhead 22；Head 2 is after pedestal 1, the blade of Qian shape
Inserting for corresponding number is then arranged according to the needs of 91 quantity of recess in the recess 91 as shown in Figure 5 on pump piston on cutterhead 22
Knife 23, time processing forming are avoided using the milling machine individually processing of recess 91 one by one, time saving and energy saving；Due to being time processing
Molding, so that the precision between recess 91 is high and consistency is good, knife plate 232 is detachably connected with cutterhead 22, convenient timely
Adjust position and quantity.
Preferable embodiment, as shown in Figure 1, further including fastening bolt 24, cutterhead 22 is provided with vertical slotting tool hole 222
And horizontal screw hole 223, screw hole 223 extend to slotting tool hole 222 from the side wall of cutterhead 22, slotting tool 23 is inserted into slotting tool hole
In 222, fastening bolt 24 and screw hole 223 cooperate to hold out against knife plate 232, so that connection fastening, replacement are convenient.
Preferable embodiment, as shown in Figure 1, pedestal 1 includes support shaft 11, terminal pad 12, chuck 13 and pressing plate 14,
One end of support shaft 11 is supported on ground or board, and the other end of support shaft 11 is connect with 12 bearing of terminal pad, chuck 13
It is erected in terminal pad 12 by bearing rotation, threaded rod 132 and at least three adjusting pawl poles 131 is provided on chuck 13,
Can be fixed using pawl pole 131 is adjusted by piston when work, pressing plate 14 is connect with threaded rod 132, and pressing plate 14 is leaned on by threaded rod 132
Close or separate adjusting pawl pole 131, so that piston placement will not steadily upwarp, it is ensured that the blade vertical cut of Qian shape needs to infuse
The diameter of meaning, pressing plate 14 should be less than piston to be produced, avoid colliding with the edge of a knife 234, can also be corresponding in pressing plate 14
The position setting notch of the edge of a knife 234 is to prevent from interfering.
Preferable embodiment, as shown in Figure 1, Figure 4 and Figure 5, terminal pad 12 are provided with elastic card bead 122, and chuck 13 is set
Several grooves 133 cooperated with elastic card bead 122 are equipped with, several grooves 133 are evenly distributed on chuck 13, in piston
When upper notch 91 is more, in addition to the slotting tool 23 of preparation corresponding number, it can also be inserted by slotting tool 23 primary rear by rotation company
Disk 12 is connect, elastic 122 mating groove 133 of card bead is positioned, is then once inserted into again, is finally completed all recesses 91
Processing, can effectively save the stock quantity of cutterhead 22 and slotting tool 23；For example, 133 interval angles B of adjacent grooves is 30 °, knife
23 quantity of slotting tool on disk 22 is six, and when 91 quantity of recess is 12, first processes six recesses 91 with slotting tool 23, so
Terminal pad 12 is rotated afterwards, and by 133 interval angles of groove, elastic card bead 122 positions 30 ° of differences, then is processed with slotting tool 23
Remaining six recesses 91 out complete the processing of a greater number recess 91, convenient and efficient and saving eventually by less slotting tool 23
Frock clamp.
