The specific embodiment
The first embodiment
Fig. 1 is the summary pie graph of the phase adjusting apparatus 40 of the first embodiment of the present invention, and Fig. 2 means the figure of mensuration part with the relation of the system of mensuration of above-mentioned phase adjusting apparatus 40.
In Fig. 1, support portion 2 is arranged on the pedestal 9 on pallet 8, and eccentric work piece 1 is positioned on support portion 2.Non-contact displacement transducer 3 is arranged on the position on above-mentioned pedestal 9.One end of above-mentioned workpiece 1 rotates by rotating mechanism 6 under the state being blocked by chuck 5.Detent mechanism 4 can be arranged on the top of eccentric work piece 1 up or down, is the mechanism of mechanically eccentric direction of eccentric work piece 1 roughly being located.
In Fig. 2, by chuck 5, controlling under the state of eccentric work piece 1 one end with eccentric part 1a and bearing portion 1b, once make rotating mechanism 6 rotations by driving governor 11, from non-contact displacement transducer 3a, the 3b output measured signal in the face of above-mentioned eccentric part 1a and bearing portion 1b setting, by AD converter 10, convert data signal to, be transported to the control device 13 that computer by the computing of stipulating etc. forms.Now, from detecting the signal of rotary encoder 7 outputs of the anglec of rotation, by counter 12, convert pulse signal to, be transported to equally control device 13.
The operating process of below utilizing Fig. 3 to measure with regard to above-mentioned phase adjusting apparatus 40 describes.First, select the type into horizontal phasing control, the position etc. of automatically changing sensor 3 according to the diameter of eccentric part and offset arranges (step 100).Then to phase adjusting apparatus, supply with workpiece 1 (step 101), then carry out the interim phase bit (step 103) of the direction of principal axis location (step 102) of workpiece and the displacement of eccentric part.Then, utilization has the chuck 5 of rotating part and controls workpiece 1 (step 104), make workpiece 1 rotation (step 105), measure the eccentric part corresponding with the anglec of rotation, the displacement (step 106) of bearing portion, proceed rotation, measure until measured the rotating range (step 107) setting.Once complete the mensuration of all setting ranges, according to the displacement data relative with angle, utilize computing method to calculate the phase place (step 108) of eccentric part, rotate the workpiece to the phase place (step 109) that combines the phase place calculating and the deviant of setting in advance (explanation subsequently), utilize afterwards conveying device to transport out workpiece (step 110).
Fig. 4, Fig. 5 are detent mechanism 4 in said determination action and the concrete action specification of chuck 5, and Fig. 4 sees that from long axis direction the figure of eccentric work piece 1, Fig. 5 mean the figure of the phase relation of the chuck jaw 5a～5c while controlling workpiece.In the step 101 of Fig. 3, workpiece 1 from a upper operation, be transported to support portion 2 above after, in order to limit the rotating range of measuring displacement, make the detent mechanism 4 that the plate by V font forms decline, with the eccentric part 1a butt of workpiece 1, mechanically determine the roughly eccentric direction (centring) of workpiece 1.As shown in Fig. 4 (a), for example aim at the Ban4a center of V font and the bearing portion 1b center of workpiece, make plate 4a and the eccentric part 1a butt of V font, as shown in Fig. 4 (b), can make like this eccentric direction verticallydownwardly rotation (clockwise) of eccentric part 1a.In addition, although can form movably example at vertical direction with above-mentioned detent mechanism 4, consider and the interference of conveying device, also can keep out of the way mechanism fore-and-aft direction (direction of the back side of paper in Fig. 1) setting.
In step 104, the chuck 5 of phase adjusting apparatus side (being scroll chuck here) advances to the direction of workpiece 1, blocks one end of workpiece 1.Now, the influence factor of the whirling while rotating in order to reduce, when clamping, become as shown in Figure 2 and make workpiece from support portion, lift the state of several millimeters, prevent that workpiece from contacting with the position beyond chuck 5 when making workpiece 1 rotation under the state clamping, the adjustment height of support portion 2 is, the height of chuck.
Therefore, when clamping workpiece, as shown in Fig. 5 (b), by verticallydownwardly, configure chuck jaw 5b and block, can suppress workpiece and topple over downwards, suppressing the whirling of workpiece.In addition, the configuration of above-mentioned chuck jaw is straight down not limited to three chuck jaws, the quantity of pawl be 4,5 when above too.
And, the shape of chuck jaw and workpiece contact portion is as shown in Fig. 5 (c), along the formation circular arc or the circular arc identical with it that clamp the workpiece external diameter at position, thereby rocking of chuck can be controlled to rocking within the scope of the circular arc of chuck, the whirling in the time of can suppressing workpiece rotation.
Then, in step 105,106, fixation workpiece, centered by eccentric part, make workpiece rotation half-turn left and right, utilize contactless displacement transducer 3a, 3b to measure the displacement of eccentric part and bearing portion, Fig. 6 represents determination data now.According to the displacement 19 of the displacement 15 of the rotational angle detecting eccentric part of workpiece and bearing portion, transverse axis represents the anglec of rotation, and the longitudinal axis represents displacement.
As the explanation that utilizes Fig. 2 to carry out, when measuring the displacement of eccentric part and bearing portion, from being arranged on rotating mechanism, detecting the sensors such as the rotary encoder 7 output pulse corresponding with the anglec of rotation of rotatable phase, by this rotary pulsed digit counter 12 that is taken into, the every certain counting of digit counter 12 is just exported triggering signal, to the above-mentioned triggering signal of computer equal controller 13 output.By being taken into equipment such as digit counters, can change arbitrarily trigger interval, by formation and measuring speed, consistent being taken into of certainty of measurement, can form optimum measurement precision and speed, shorten the cycle of equipment.
Control device 13 receives after above-mentioned triggering signal, such as utilizing the console of can be simultaneously a plurality of points of many ADC etc. being sampled, be taken into the displacement A (θ) of the eccentric part shown in 15 and the displacement B (θ) of the bearing portion shown in 19 and they are preserved, thereby can obtain by the eccentric part of angular interval and the displacement data of bearing portion arbitrarily.
The displacement data A (θ) of the eccentric part based on here obtaining, calculates the phase place of eccentric direction, obtains the phase place of eccentric part.When calculating the phase place of eccentric part, phase place that can be using the point of displacement minimum in determination data as eccentric part, but in order to suppress the restriction of the noise of determination data or the impact of interference or angular resolution, to obtain phase place accurately, use the approximate operate approximately waiting of trigonometric function.
Specifically, utilize trigonometric function to be similar to the displacement Y=A (θ) of the eccentric part obtaining by mensuration, convert to following formula (1), the F obtaining is phase pushing figure.
Y＝D·sinE(X-F)+G (1)
D, E, F, G represent the numerical value obtaining by result of calculation.
And, if noncontacting proximity sensor 3 is used eddy current type sensor to measure the eccentric part of rotation, according to the measuring principle of the sensor 3, once increase with the distance of sensor 3, as shown in the dotted line 17a of Fig. 6, the displacement of measuring increases, and reduces with the uniformity of trigonometric function, and computational accuracy declines.Therefore, set arbitrary height 20, use these data below arbitrary height, with the curve of approximation 17 of trigonometric function, be similar to, thereby the raising of the repeatability of operation result can suppress the deviation of result of calculation, can obtain accurately phase place.
And, even if prevented the whirling of workpiece when illustrated in fig. 5 clamping, but when clamping workpiece, due to the position skew of chuck and workpiece or the skew of chuck hub and pivot etc., in any case all can produce some whirlings when making workpiece rotation, the displacement of above-mentioned whirling is added in the determination data relevant with the displacement of above-mentioned eccentric part.If use this data when calculating the phase place of eccentric part, between result of calculation and actual eccentric direction, produce skew, phase place adjustment precision likely reduces.Therefore, by the displacement 9 of the eccentric part from workpiece, deduct the displacement 19 of bearing portion, can from the determination data of eccentric part, remove the whirling composition of workpiece.And, while offsetting runout composition the displacement of the eccentric part from measured, in order to change the weighting of the locating of bearing portion, runout, also the displacement of bearing portion can be multiplied by weight coefficient α,
X(θ)＝A(θ)-α×B(θ) (2)
0≤α≤1 wherein
Obtain the displacement data X (θ) of the eccentric part of having removed whirling composition.Counteracting now the eccentric part displacement data X (θ) of runout composition in the displacement of eccentric part in Fig. 6, with 16, represent, its curve of approximation represents with 18.
In addition, contactless displacement transducer 3 in Fig. 2, be configured in workpiece 1 vertically below, also can be arranged on horizontal (back side direction of paper) of workpiece, measuring precision does not change, and because being arranged on laterally, in the cutting water of a upper operation, contained smear metal etc. is not easy to remain on sensor, the variation of the side-play amount of the measurement result in the time of can suppressing repeated measurement, the mensuration direction of therefore wishing sensor be workpiece laterally.
As mentioned above, first embodiment of the invention, owing to can the eccentric part of workpiece being adjusted to phase place accurately, therefore can be suppressed at the residual defects of grinding allowance on cylinder grinder.
By the way, at current machinery, adjust in the method for phase place, because of the deviation of diameter of work or with the phase place alignment error of produce ± 1 ° of left and right of the surface state contacting of fixture, yet use phase adjusting method of the present invention can be suppressed at ± below 0.1 °.
The second embodiment
In the first embodiment, the workpiece that has passed through high-precision phase position adjustment is transported to cylinder grinder, now importantly to keep the state of the definite phase invariant of phase adjusting apparatus to be transported to cylinder grinder.Utilize Fig. 7 just the handing-over of conveying device for this reason and conveying device and cylinder grinder move and describe.
Fig. 7 (a) is the skeleton diagram of conveying device 50 self.As shown in Fig. 7 (a), form following structure,, conveying device 50 is divided into chuck segment side 21 and fixed part side (base portion side) 22, in chuck segment side, lining 23 is set, in base portion side, be provided as the pillar 24 of guide, by pillar, utilize spring 25 that chuck segment side is lifted, thereby make lining 23 there is the free degree at above-below direction.
Fig. 7 (b) means the side view of the state of chuck 27, the 28 handing-over workpiece 1 from conveying device 50 to cylinder grinder, and Fig. 7 (c) is its front view.
Because conveying device 50 has the free degree at above-below direction, therefore, when chuck 27,28 handing-over to cylinder grinder, make to be transferred the position of top slightly that workpiece 1 that device 50 carries stops at the receiver side chuck 27 of cylinder grinder, utilize the chuck 28 of cylinder grinder to block workpiece 1, chuck segment side is pulled up by the flexible of spring mechanism of conveying device, can absorb the position skew of the chuck 26 of conveying device and the chuck of cylinder grinder 27,28, can utilize chuck each other the posture of holding workpiece block unchangeably workpiece.
Then, pull down the chuck of conveying device 50, thereby completed the conversion that clamps from conveying device to cylinder grinder.Certainly, clamping conversion and also can carry out in the same manner as described above from phase adjusting apparatus to conveying device.
As mentioned above, utilize spring etc. to make conveying device be formed on the multi-direction structure with the free degree, thereby while joining between phase adjusting apparatus and conveying device and conveying device and the chuck of cylinder grinder, can utilize chuck each other the posture of holding workpiece clamp unchangeably conversion, can suppress because clamping the workpiece posture change that causes of conversion.Consequently keep phase invariant that phase adjusting apparatus determines and be transported to cylinder grinder, carry out the grinding of eccentric part, thus the residual defects of the finished surface in the time of can suppressing grinding.
The 3rd embodiment
According to first, second embodiment, can keep the phase invariant that determined by phase adjusting apparatus and be transported to cylinder grinder, eccentric part is carried out to grinding, but after phase adjusting apparatus has calculated phase place, when conveying device and cylinder grinder clamp conversion, minor shifts owing to clamping etc., by phase adjusting apparatus calculate, the phase place of rotation is likely offset.Its result likely produces skew at the pivot of cylinder grinder and the center of eccentric part, and the residual defects of grinding allowance occurs when grinding.And, even if there is not residual defects, the phase deviation that also likely produces eccentric part within the scope of rough machined grinding allowance, the residual defects while producing grinding because of this skew and machining deviation etc.
In the 3rd embodiment, the result that phase adjusting apparatus is calculated is set and compensates and rotate the function of angle arbitrarily, the result of the angular deflection based on when the cylinder grinder grinding, the angle that phase adjusting apparatus is calculated is added compensation rate.
Fig. 8 represents the flow process of the machining production line from phase adjusting apparatus to cylinder grinder, for having adjusted phase place at phase adjusting apparatus 40, keep this phase invariant and be transported to the workpiece on cylinder grinder 60 by conveying device 50, at cylinder grinder 60, measure the phase deviation (checking operation 70) of eccentric part, this side-play amount is fed back to phase adjusting apparatus 40.Thus, the skew that can add on phase adjusting apparatus 40 while carrying chuck etc., make the direction of eccentric part and the pivot of cylinder grinder of workpiece consistent, therefore the residual defects on the grinding surface of eccentric part in the time of not only can suppressing grinding, and in the roughing of a upper operation, reduce the reduction of grinding allowance, cut down the grinding time, thus the cycle that can cut down cylinder grinder.
The 4th embodiment
In the 3rd embodiment, carried out following explanation,, by after workpiece setting is on cylinder grinder, measure the deviation angle at the center of the pivot of cylinder grinder and the eccentric part of workpiece, upwards the calculating angle of the eccentric phase of the phase adjusting apparatus of an operation is added compensation rate, thus the phase pushing figure of the eccentric part in the time of can reducing grinding.The 4th embodiment is the scheme that the assay method of the phase pushing figure of the eccentric part on such cylinder grinder is proposed.
Fig. 9 is the skeleton diagram that explanation makes the displacement meters such as dial ga(u)ge 30 and eccentric part butt, the mensuration oscillation capacity of eccentric part and the method for runout direction under the state being arranged on cylinder grinder.When representing to be arranged on cylinder grinder, Fig. 9 (a) without the state of skew, specifically represents pivot 32 state consistent with the center 33 of the eccentric part of workpiece of cylinder grinder.In addition, the bearing portion center of 31 expression workpiece.While making cylinder grinder rotation under this state, displacement and the anglec of rotation of eccentric part periphery has nothing to do, is constant.And as shown in Fig. 9 (b), in the situation that the pivot 32 of cylinder grinder and 33 skews of the center of the eccentric part of workpiece, if make cylinder grinder rotation under this state, the displacement of eccentric part periphery changes according to the anglec of rotation.Because side-play amount and the oscillation capacity of eccentric part determined by geometrical relationship, therefore by measuring the runout amplitude of displacement, can calculate the side-play amount β of eccentric part.But said method must make cylinder grinding attachment stop in order to measure phase pushing figure, therefore there is the problem of the operating rate reduction of production line.
Figure 10 is the explanation of assay method of the phase pushing figure of the new eccentric part for addressing the above problem, when carrying out the roughing of eccentric part external diameter, carry out chamfer machining, to making the identical workpiece in center of the center of chamfered section and the roughing external diameter of eccentric part carry out grinding, the phase deviation of calculating eccentric part according to the big or small difference of the chamfering width after grinding.
Figure 10 (a) represents to have carried out rough machined workpiece, carry out chamfer machining, thereby the center of eccentric part is consistent with the center of chamfer site when carrying out roughing simultaneously.Figure 10 (b) is the completion diameter 35 from the rough machined external diameter 34 (dotted line) through chamfer machining to the grinding on cylinder grinder, when having removed allowance, if the axle center of the eccentric part of the pivot of cylinder grinder and workpiece is offset, chamfering width b1 and the b2 of the left and right of the eccentric direction of the eccentric part of workpiece down time are different.Because the side-play amount of this chamfering stand out and eccentric part is determined by geometrical relationship, therefore, by measuring poor (b1-b2) of chamfering width, can obtain the side-play amount β of eccentric part, to the result of calculation of phase adjusting apparatus, add compensation rate β.
As mentioned above, the phase deviation of the chamfering width measurements eccentric part by the eccentric part after grinding, phase deviation when thereby arrestment or production line just can not measured grinding, not only can improve the operating rate of production line, and can measure expeditiously phase pushing figure.And, to phase adjusting apparatus feedback phase side-play amount, thereby can adjust accurately phase place, therefore can eliminate the residual defects of finished surface.And in batch production processing, can change the compensation rate of the calculating angle of phase adjusting apparatus, therefore not stopping production line of batch just can adjust angle compensation amount expeditiously.
