As shown in Figure 1, the present embodiment needs processing groove width to be the keyway of 90mm, present embodiments provides a kind of slotting machine inner hole key slot line school cutter detector, comprises locating piece 1, is arranged on slide block 2 on locating piece 1 and back-up block 3.The width of locating piece 1 is 290mm, length is 57 mm, locating piece 1 have groove along its length, groove is arranged between two parties, the groove width of groove is 110 mm, the both sides of locating piece 1 are provided with segmental arc 4, and segmental arc 4 mates with inner hole of workpiece or tangent, and two segmental arcs 4 are symmetrical along the center line of the length direction of groove.The width of slide block 2 is also 110mm, slide block 2 and groove are slidably connected, one end of slide block 2 is provided with first detection body 5 of mating with keyway shape, the width of the first detection body 5 is the lower deviation that 110mm deducts keyway, first detection body 5 is arranged between two parties on the width of slide block 2, the other end of slide block 2 is provided with the second detection body 6, the width of the second detection body 6 is that this width of 90mm(mates with the size of another inner hole key slot), the two ends of the second detection body 6 and the justify align of the first detection body 5, and the second detection body 6 is recessed along slide block 2.The length direction of slide block 2 is provided with groove, slide block 2 is provided with clamping screw and gathering sill 7, and gathering sill 7 is arranged along the length direction of groove, and on locating piece 1, correspondence is provided with connecting hole, clamping screw can pass gathering sill 7 and connecting hole, is located between slide block 2 and locating piece 1 by clamping screw.The quantity of back-up block 3 is two, two back-up blocks 3 are in the same plane, back-up block 3 stretches out the both sides of locating piece 1 respectively, back-up block 3 is provided with set bolt, back-up block 3 is provided with chute 8, and on locating piece 1, correspondence is provided with installing hole, and set bolt can pass chute 8 and installing hole, located by set bolt between back-up block 3 and locating piece 1, back-up block 3 and slide block 2 are positioned at sustained height plane.
It should be noted that the segmental arc 4 of locating piece 1 is by Linear cut one-shot forming, guarantee that two segmental arcs 4 of locating piece 1 are symmetrical.
Regulate the using method of set bolt and clamping screw: unscrew set bolt or clamping screw, back-up block 3 or slide block 2 can slide along chute 8 or gathering sill 7, back-up block 3 or slide block 2 is extended or in retraction locating piece 1.Be tightened bolt or clamping screw, and back-up block 3 or slide block 2 can compress by set bolt or clamping screw, and back-up block 3 or slide block 2 just can not move along locating piece 1.
Two back-up blocks 3 are stretched out the both sides of locating piece 1, and by set bolt, two back-up blocks 3 are positioned on locating piece 1, because two back-up blocks 3 are in the same plane, therefore when being placed on workpiece end face by two back-up blocks 3, locating piece 1 and slide block 2 are all parallel with the end face of workpiece.
As shown in Figure 2, use the method for this structure school cutter line as follows:
First will need the semi-finished product location and installation of processing keyway on the workbench of slotting machine, again by with need to process the first detection body 5(that width of keyway mates and be 110mm) be mounted to locating piece 1 one end near segmental arc, first detection body 5 is stretched out groove, by referring to the scale on slide block 2, the length making the first detection body 5 stretch out groove is mated with needing the degree of depth of processing keyway, and screws clamping screw and located by slide block 2.Then two back-up blocks 3 are stretched out the both sides of locating piece 1, and two back-up blocks 3 are located by the bolt that is tightened, be positioned on the end face of sample workpiece by the first detection body 5 of two back-up blocks 3 and slide block 2, two segmental arcs 4 of locating piece 1 offset with the inwall of semi-finished product endoporus.Next, rotating locating blocks 1, making the end face of the second detection body 5 parallel with slotting tool 9 anterior angle chisel edge plane (or slotting machine workbench), when checking whether parallel, can adopt dial gauge.Finally draw the wide line of key and keyway bottom line with marking-off pin along the outer rim of the first detection body 5, slotting tool 9 is using the second detection body 6 now as school cutter benchmark.
Feature radius 195mm shown in Fig. 2, inner hole key slot dark 17.4, keyway symmetry requires 0.03mm, if press line tool setting bias element center 0.2mm, workpiece keyway symmetry mismachining tolerance only has 0.018mm (0.2 ÷ 195 × 17.4).
As shown in Figure 3, use the method for this structure to workpiece sensing as follows:
First this structure kept the state of school cutter line constant, regulate set bolt, make two back-up blocks 3 be positioned at the space of locating piece 1.Offseted by the inner hole wall of workpiece after the segmental arc 4 of locating piece 1 and completion of processing, the first detection body 5 is inserted in keyway again, and moving axially along inner hole of workpiece after completion of processing, thus the workpiece after completion of processing is detected.
Embodiment 2
As shown in Figure 4, in the present embodiment, the inner hole key slot width of sample workpiece becomes 90mm, and the width of this inner hole key slot mates with the second detection body 6, and the present embodiment only needs the location swap by the first detection body 5 in embodiment 1 and the second detection body 6.
Embodiment 3
When need to carry out ruling be symmetrical two keyway arrangements time, after the line completing a keyway, workpiece can be rotated 180 degree, then carry out the line of second keyway, operation is in the extreme simply and conveniently.
Embodiment 4
The knife rest of slotting tool is removably connected with a correcting block, particularly, knife rest is milled with groove, correcting block is connected on knife rest by groove, and when correcting block is connected on knife rest, blade face or the slotting machine workbench of correcting block and slotting tool are parallel.Because the area in the blade face of slotting tool is less, slotting machine workbench and the second detection body distant, therefore to be provided with correcting block to facilitate the second detection body be with reference to comparing with correcting block.When slotting tool is in running order, correcting block need be taken off from knife rest, with the normal work preventing correcting block from disturbing slotting tool.
For a person skilled in the art, under the prerequisite not departing from structure of the present invention, can also make some distortion and improvement, these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
