Specific embodiment
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing.
A kind of shaft-like workpiece Double End positioning table, including the head frame 2 and tailstock 1 being oppositely arranged, 1 lower section of head frame 2 and tailstock
It is respectively equipped with a set of servo walking mechanism, the discrete axial for controlling head frame 2 and tailstock 1 is walked；In order to guarantee transmission essence
Degree, servo walking mechanism preferably use motor lead screw mechanism；As shown in Figure 1, wearing screw rod 1 on head frame 2, screw rod 1 connects
Servo motor 1 is connect, head frame 2 is moved along screw rod 1；Screw rod 2 14 is worn on tailstock 1, screw rod 2 14 connects servo motor two
15, tailstock 1 is moved along screw rod 2 14.
First sleeve 9, setting telescopic first top 8 in first sleeve 9, the first top 8 tail are installed on head frame 2
The first displacement sensing for holding out against cylinder 10, installing for measuring the first top displacement on head frame 2 that portion's connection drives its flexible
Device 11, the first displacement sensor 11 also may be mounted in first sleeve 9, be such as mounted in first sleeve 9, then can be by straight
The stroke for connecing measurement first top 8 is realized；The piston rod 10a that cylinder 10 is held out against in the present embodiment is that structure is stretched out at both ends, living
The head stopper rod 10a is connected to the first top 8 tail portion by fastener, and the tail portion piston rod 10a, which is pierced by, holds out against cylinder 10；First displacement
Sensor 11 uses contact digital sensor (such as Panasonic HG-S1032), directly with the tail portion that holds out against 10 piston rod 10a of cylinder
Connection, the indirectly displacement of measurement first top 8；If the piston rod 10a for holding out against cylinder 10 is single head, only stretched out in front end,
Then contact digital sensor can also be arranged in parallel and relatively fixed with piston rod 10a, realize the survey being displaced to piston rod 10a
Amount.
Second sleeve 6, setting telescopic second top 4 in second sleeve 6, the second top 4 tail are installed on tailstock 1
Portion connects bounce cylinder 5, second displacement sensor 7 is installed in second sleeve 6, second displacement sensor 7 is for detecting second
Top 4 whether dieback in place.Wherein, the cylinder pressure of bounce cylinder 5 is less than the cylinder pressure for holding out against cylinder 10 herein, when first
Top 8 and second top 4 all contradict shaft-like workpiece after, can be by shaft-like workpiece due to holding out against 10 pressure of cylinder greater than bounce cylinder 5
It is pushed up toward 5 direction of bounce cylinder, until the dead-centre position of bounce cylinder 5 is arrived on top.The first displacement sensor 6 and second displacement herein
Sensor 7 is coupled with two sets of servo walking mechanisms respectively, for feeding back measurement data to servo-system, adjusts servo walking mechanism
Displacement.
In order to place workpiece conveniently, the support 3 of support workpiece can also be set on head frame 2, and support 3 is supported under workpiece
Side, and guarantee that workpiece both ends are exposed, it avoids interfering with gear rolling rounding machine cutter 17.
The specific work process of positioning table is as follows in the present embodiment:
As shown in Fig. 2, first shaft-like workpiece 16 is put on support 3；
As shown in figure 3, first top 8 stretches out from first sleeve 9, second top 4 stretches out from second sleeve 6；
As shown in figure 4, servo motor 2 15 drives tailstock 1 to the mobile set distance H1 in 2 direction of head frame, servo motor 1
Drive head frame 2 mobile to 1 direction of tailstock, the first top 8 and second top 4 difference contact workpiece both ends；
As shown in figure 5, servo motor 1 continues to drive head frame 2 mobile to 1 direction of tailstock, simultaneously as top cylinder
Cylinder pressure be greater than bounce cylinder 5, bounce cylinder 5 bounces back, until bounce back to dead point, workpiece is held out against；Head frame 2 is mobile at this time
Distance is set distance H2, and when holding out against every time, the numerical value of H1 and H2 are constant；Then second top 4 due to bounce cylinder 5 it is each
It is all compressed into dead point, therefore second top 4 each position in workpiece pre-tightening is fixed, the position of workpiece first end face
It is determining every time；So workpiece is because the length tolerance A that welding generates then is fed back by first top 8 displacement, i.e.,
First top 8 position when holding out against every time is variation；The variation is fed back in the decrement for holding out against cylinder 10, that is, holds out against gas
The axial displacement value of 10 piston rod 10a of cylinder and the difference of theoretical value, the as length tolerance of workpiece；When to first position sensor 11
The established standards workpiece standard displacement that it is generated when clamping, according to the difference with the standard displacement, above-mentioned length tolerance
The as actually measured displacement of the first displacement sensor 11 subtracts standard displacement.Servo-system passes through the first displacement sensor 11
The length tolerance obtained obtains the position of workpiece second end face in conjunction with known first end face position；
As shown in fig. 6, servo motor 1 drives head frame 2 after workpiece pre-tightening, servo motor 2 15 drives tailstock 1, jointly
To 1 direction moving distance H3 of tailstock, 1 side end of tailstock of workpiece enters the machining position of gear rolling rounding machine cutter 17 at this time；
As shown in fig. 7, servo motor 1 drives head frame 2, servo motor two after 1 side end of tailstock of workpiece processes
15 drive tailstock 1, and jointly to 1 direction moving distance H4+A of tailstock, 2 side end of head frame of workpiece enters gear rolling rounding machine cutter 17 at this time
Machining position.
It should be noted that the position of gear rolling rounding machine cutter is fixed.The shaft-like workpiece Double End positioning table of this programme is not
It is suitable only for the spline processing of gear rolling machine, is readily applicable to the occasion to the processing of axial workpiece both ends of other equipment.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvement and replacement can also be made, these change
It also should be regarded as the protection scope of the utility model into replacement.
