Description
Technical Field
The utility model belongs to the technical field of machining and specifically relates to an aligning device of many keyways of milling process axle.
Background
According to the processing demand, the key groove of processing axle class product is not only had symmetrical keyway, and asymmetric keyway in addition, and often not well fix a position the position of a plurality of key grooves to the milling process of asymmetric keyway, and the mode of marking off alignment is then adopted to current technical means, nevertheless because operation workman manual operation, has great error, causes the inaccurate condition of a plurality of keyway location.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that needs to solve provides an aligning device of many keyways of milling process axle, simple structure utilizes polygon alignment piece and percentage table, can pinpoint the position of asymmetric keyway, and the precision is high, and the error is little.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: the aligning device for milling the multiple key grooves of the shaft comprises a polygonal aligning block and a dial indicator, wherein the polygonal aligning block is fixedly arranged at the center of the end face of the processing shaft, the number of edges of the polygonal aligning block is the same as the number of the key grooves, and the dial indicator is fixedly arranged on a machine tool.
The utility model discloses technical scheme's further improvement lies in: the center of the polygonal alignment block and the two connected sides of the polygonal alignment block are fixedly arranged on the end face of the processing shaft through bolts.
Due to the adoption of the technical scheme, the utility model discloses the technological progress who gains is:
1. the utility model has simple structure, can accurately position the asymmetric key groove by utilizing the polygon alignment block and the dial indicator, and has high precision and small error;
2. the utility model discloses application scope is wide, and the processing demand of many keyways is satisfied to the polygon alignment piece that keyway quantity preparation limit number and keyway quantity are the same according to needs processing.
Drawings
FIG. 1 is an isometric view of a polygonal alignment block of the present invention mounted on a machining spindle;
fig. 2 is a sectional view taken along line a-a of fig. 1 according to the present invention;
figure 3 is a left side view of figure 1 of the present invention;
the device comprises a polygonal alignment block 1, a polygonal alignment block 2, a processing shaft 3, a key groove 4 and a bolt.
Detailed Description
The present invention will be described in further detail with reference to the following examples:
the utility model provides an aligning device of many keyways of milling process axle, includes polygon alignment piece 1 and percentage table to polygon alignment piece 1 is the pentagon for the example, as shown in fig. 1 to 3, polygon alignment piece 1 is fixed to be set up in 2 terminal surface central points of processing axle and puts, and is concrete, all sets up on 2 terminal surfaces of processing axle through bolt 4 is fixed between the center of polygon alignment piece 1 and the continuous both sides. The number of the sides of the polygonal alignment block 1 is the same as that of the key grooves 3, and the dial indicator is fixedly arranged on the machine tool.
The using method comprises the following steps:
s1, manufacturing the polygonal alignment blocks 1 with the same number as the key slots 3 in advance according to the number of the key slots 3 to be processed, and detecting that the accuracy of the polygonal alignment blocks 1 is qualified;
s2, fixedly arranging the polygonal alignment block 1 on the end face of the processing shaft 2 through a bolt 4;
s3, rotating the processing shaft 2, and contacting one side of the polygon through a dial indicator contact to enable one side of the polygon alignment block 1 to be placed in a vertical state;
s4, starting the machine tool, and processing the key groove 3 corresponding to the edge in the polygonal alignment block 1 in the vertical state;
and S5, repeating the steps S3 and S4, sequentially aligning other sides of the polygonal aligning block 1 to be in a vertical state, and then sequentially milling the corresponding key grooves 3 until all the key grooves 3 are milled.
The utility model discloses simple structure utilizes polygon alignment piece 1 and percentage table, can pinpoint the position of asymmetric keyway, and the precision is high, and the error is little, according to 3 quantity preparation limits of keyway 3 that need process and the same polygon alignment piece 1 of keyway 3 quantity, satisfies the processing demand of many keyways.
