Description
Technical field
The present invention relates to overlap evaluating apparatus.
Background technology
In the application valve body of automatic transmission, be provided with a plurality of oilholes, these oilholes are connected to each other, and form the oil circuit of oil circulation.
While forming oilhole in application valve body, at the cross part of oilhole and oilhole, produce so-called overlap.Therefore, attempt by the disclosed deburring device etc. of cutting in high pressure washing and brush and patent documentation 1, remove the overlap producing at cross part, but be difficult to whole overlaps to be removed completely.
The in the situation that of automatic transmission, when remaining in overlap in oil circuit when not removing overlap and coming off, the overlap coming off becomes snotter for operation valve etc., thereby becomes the reason of the action failure etc. of automatic transmission.
Therefore, to residual overlap, whether be to have the dangerous overlap that comes off to confirm, for there being the dangerous overlap that comes off, again with cutting deburring device etc., remove, for the dangerous overlap that do not come off, make it remain unchanged and retain.
Patent documentation 1:(Japan) Unexamined Patent 3-281163 communique
At present, to whether being to have the confirmation of the dangerous overlap that comes off to judge as follows, for example, with the core of propelling pencil, press overlap, in the situation that core fractures, being judged to be is the dangerous overlap that do not come off, when core does not fracture and in situation that overlap fractures, being judged to be is to have the dangerous overlap that comes off.
But the situation of such confirmation method likely makes the propelling pencil fractureing become snotter.
So, require can not produce and can become the fragment of snotter etc., can determine whether more simply it is the method that has the dangerous overlap that comes off.
Summary of the invention
The invention provides a kind of overlap evaluating apparatus, it is configured to possesses: the main part of tubular; Spindle unit, it is by the supporting of described main part and can move vertically, and makes to have distolateral being positioned at outside described main part with the abutting part of overlap butt; Force application apparatus, it applies the acting force of regulation to described spindle unit, to resist the counter-force of bearing from described overlap when pressing described overlap by described abutting part.
According to the present invention, when the acting force of regulation is greater than the counter-force of bearing from overlap while pressing overlap, spindle unit is maintained at original position.And when the counter-force of bearing from overlap is larger than the acting force of force application apparatus, spindle unit bears from the counter-force of overlap and to other end side shifting.
Therefore, in the situation that the intensity of overlap enough and not comes off is dangerous, the pressing force that abutting part is pressed overlap becomes large, surpasses the moment of the acting force of regulation in the counter-force of bearing from overlap, and spindle unit moves to the direction of leaving overlap.On the other hand, in the situation that the intensity of overlap is not high, because the overlap midway press overlap by abutting part can be fractureed, therefore, spindle unit can not move to the direction of leaving overlap.
Thus, according to spindle unit, whether move, can determine whether it is to have the dangerous overlap that comes off.In addition, now can not produce and can become the fragment of snotter etc.

In nut 17, be screwed into the bulb stopper 30 that periphery is provided with ridge, bulb stopper 30 makes groove 232 butts by the ball 30b of the front end of the spring 30a application of force and the plunger receiving portion 23 of spindle unit 20.
Under this state, the plunger receiving portion 23 at spindle unit 20, has acted on acting force via the ball 30b of bulb stopper 30, has limited its moving axially to spindle unit 20.
In the present embodiment, because being is screwed into nut 17 by bulb stopper 30, thus, and when bulb stopper 30 is installed, the position of the bulb stopper 30 in adjustable nodal axisn Y-direction.Therefore, by changing bulb stopper 30, be screwed into the length h of nut 17, can regulate the acting force that acts on plunger receiving portion 23 from bulb stopper 30.
In the present embodiment, plunger receiving portion 23 is set to bear the mode of the acting force of 500gf from bulb stopper 30, as long as make spindle unit 20 (plunger receiving portion 23) be no more than 500gf to axially movable power, spindle unit 20 will be pushed to ball 30b and can not be to moving axially.

Otch 13b is along becoming dummy line lm1, the lm2 that relative position is parallel to each other across central shaft X and arranging.The width W 2 of otch 13b forms can insert the width of spline pin 25 described later.
In addition, the depth D s apart from outer peripheral face 13c of otch 13b is set as, at spline pin 25, be inserted under the state of otch 13b, spindle unit 20 (abutting part 21, axial region 22, plunger receiving portion 23, limiter 24, bolt B) is configured in the degree of depth (with reference to Fig. 1 (a)) on central shaft X.
As shown in Fig. 1 (a), spindle unit 20 possesses: front end has the axial region 22 of abutting part 21; Plunger receiving portion 23; Limiter 24; Spline pin 25.
As shown in Fig. 2 (b), at the front end of axial region 22, be provided with the tabular surface 22a with central shaft X quadrature.The diameter D5 of tabular surface 22a is less than the outer diameter D of axial region 22 6, and the front of axial region 22 is along with undergauge towards tabular surface 22a and gradually.
At the central portion of tabular surface 22a, by being welded with the abutting part 21 of cylindrical shape.Abutting part 21 arranges along central shaft X, has specified length L1 (for example 3mm).
Abutting part 21 penetrating length direction total lengths have same diameter (for example 0.5 φ), and its front end face 21a is the same with above-mentioned tabular surface 22a, becomes the tabular surface with central shaft X quadrature.
In the present embodiment, this front end face 21a, when overlap intensity is evaluated, becomes the bearing surface with the direct butt of overlap.
At this, in the overlap evaluating apparatus 1 of embodiment, become the structure of pressing overlap with abutting part 21, at least abutting part 21 need to have while pressing not the hardness of regulation that can bending.In the situation that by the formation abutting parts 21 such as cut of axial region 22, in order to make abutting part 21 there is hardness, need to quench, therefore make cost of manufacture increase.By abutting part 21 during with axial region 22 splits design, as long as at least abutting part 21 has the hardness of regulation, just do not need axial region 22 all to form high rigidity.
In addition,, while this abutting part 21 being arranged on to the front end of axial region 22 by welding, do not need quenching as above.Therefore, can suitably prevent the rising of cost of manufacture.
The roughly total length of axial region 22 penetrating length directions forms (with reference to Fig. 1 (a)) with same diameter.As shown in Fig. 3 (a), the outer peripheral face in the base end part 22b of axial region 22 side, is provided with external thread 22c.
One end in axial region 22 sides of plunger receiving portion 23, be provided with than the boss portion 231 of plunger receiving portion 23 paths, in the central authorities of this boss portion 231, connect boss portion 231 until the half-way of plunger receiving portion 23 and be formed with threaded hole, this threaded hole is formed with internal thread 23a in interior week.
Therefore, the base end part 22b side of axial region 22 is so that external thread 22c is screwed into the state of internal thread 23a and plunger receiving portion 23 to link.
Plunger receiving portion 23 has cylindrical shape, and as shown in Fig. 4 (a), its outer diameter D 7 is less than the inside diameter D 4 of the through hole 14 on plunger installation portion 13.
Thus, plunger installation portion 13 can be interior the moving axially along central shaft X of through hole 14.
As shown in Fig. 3 (a), in plunger receiving portion 23, the outer peripheral face of central portion is in the longitudinal direction formed with the chimeric groove 232 of ball 30b of bulb stopper 30, and this groove 232 formed around circumferentially the spreading all over all-round of central shaft X.
At plunger receiving portion 23 and other ends boss portion 231 opposition sides, along central shaft X, be provided with the threaded hole with internal thread 23b.
In this threaded hole, be screwed with bolt B, at the other end of plunger receiving portion 23, via bolt B, be fixed with limiter 24.
Fig. 4 (b) is the B-B sectional view in Fig. 3 (a), is (c) only to represent the local figure of the limiter 24 in (b), and be the figure that limiter 24 is described respectively.
Limiter 24 has round-shaped from axially seeing of central shaft X.
As shown in Fig. 3 and Fig. 4 (c), the outer diameter D 8 of limiter 24 is identical with the external diameter of limiter 24 sides of plunger installation portion 13, from central shaft X axially and plunger installation portion 13 butts and stop up the opening of through hole 14.
At the central portion of limiter 24, through-thickness connects limiter 24 and is provided with and makes bolt B insert logical bolt hole 24a.
On the face of plunger receiving portion 23 sides of limiter 24, to surround the mode of bolt hole 24a, be provided with the recess 24b (with reference to Fig. 4 (b), (c)) of the inside diameter D 7 of mating with the external diameter of plunger receiving portion 23.In addition, on limiter 24 and faces plunger receiving portion 23 opposition sides, to surround the recess 24c (with reference to Fig. 3 (a)) of the internal diameter that the mode of bolt hole 24a is provided with the head that can take in bolt B.This recess 24c forms can take in the degree of depth of the head B1 of bolt B.
In limiter 24, in the position of the radial outside of bolt hole 24a, to plunger receiving portion 23 side openings be provided with for inserting the pin insertion hole 24d of spline pin 25.In addition, in the position of mating with this pin insertion hole 24d, to plunger receiving portion 23 opposition side openings be provided with than the through hole 24e of pin insertion hole 24d path.
The degree of depth h2 of pin insertion hole 24d forms with the length shorter than the axial length L of spline pin 25 2.Therefore,, when spline pin 25 is inserted into pin insertion hole 24d, one end of spline pin 25 is more outstanding than the face of plunger installation portion 13 sides.
In the present embodiment, spindle unit 20 is inserted to main part 10 from plunger installation portion 13 sides, when the ball 30b of bulb stopper 30 is arranged on the position chimeric with the groove 232 of plunger receiving portion 23 (with reference to Fig. 3 (a)), 25 of spline pins are inserted into the otch 13b of plunger installation portion 13.
Under this state, at the outstanding spline pin 25 of the limiter 24 of spindle unit 20, be inserted into the otch 13b of main part 10, therefore, spindle unit 20 is set up with the state with respect to main part 10 splines.
In addition, spindle unit 20 (abutting part 21, axial region 22, plunger receiving portion 23, limiter 24, bolt B) is disposed on central shaft X by being inserted into the spline pin 25 of otch 13b.Therefore,, in the scope that is positioned at through hole 14 of spindle unit 20, on spindle unit 20, just the ball 30b of bulb stopper 30 contacts with lining 15.
Therefore, spindle unit 20 is limited by the acting force from bulb stopper 30 in the movement to axial, and, in the situation that on spindle unit 20 there be recently from the large power of the acting force of bulb stopper 30 and to circumferential movement effect, take and act on as main with the sliding resistance of lining 15.
Action to overlap evaluating apparatus 1 describes.
Fig. 5 is the figure that the evaluation of the overlap T of the cross part in oilhole A and oilhole B is described, (a) be the figure that the state before the evaluation of overlap is described, (b) being figure spindle unit 20 being described to axially movable situation according to the evaluation of overlap, is (c) figure situation of overlap T bending being described according to the evaluation of overlap.
First, as shown in Fig. 5 (a), from the direction of intersecting with overlap T, the abutting part of spindle unit 20 21 is close to overlap T, as shown in dummy line in figure, make abutting part 21 and overlap T butt.
When this state makes overlap evaluating apparatus 1 move to the direction of pressing overlap T with abutting part 21, on spindle unit 20, effect is from the counter-force of overlap T, and the power that the direction that spindle unit is represented to arrow F2 in figure moves works.
Bulb stopper 30 is owing to being to utilize acting force that spring 30a produces to make groove 232 butts of ball 30b and plunger receiving portion 23, therefore, upper in plunger receiving portion 23 (spindle unit 20), in the directive effect that arrow F1 represents in figure, there is acting force, limited the axial movement of spindle unit 20.
As shown in Fig. 5 (b), overlap T has while not coming off dangerous enough intensity, though overlap T be subject to that abutting part 21 presses can bending yet.Like this, because act on and having corresponding to act on the counter-force F2 of the pressing force of overlap T from abutting part 21 on spindle unit 20, so than be input to large moment of directed force F 1 of spindle unit 20 from bulb stopper 30, ball 30b is brought to and departs from groove 232 to the direction of leaving plunger receiving portion 23 at this counter-force F2.
Thus, the integral body of spindle unit 20 moves to the direction of leaving overlap T, and the spline pin of limiter 24 25 departs from the otch 13b of plunger installation portions 13, becomes the state of plunger receiving portion 23 and the face butt of the downside of through hole 14.
That is, in the situation that overlap T has the dangerous enough intensity that do not come off, spindle unit 20 is to moving axially, and limiter 24 comes off from the plunger installation portion of main part 10.Utilizing the movement of this spindle unit 20 can grasp overlap T is the dangerous overlap that do not come off.
On the other hand, as shown in Fig. 5 (c), when overlap T does not have enough intensity, overlap T bending when being subject to abutting part 21 and pressing.
In this case, in the moment of overlap T bending, the counter-force F2 that abutting part 21 bears from overlap T disappears.In addition, because the counter-force F2 from overlap T is large unlike the directed force F 1 from bulb stopper 30, therefore, spindle unit 20 is maintained at the initial position shown in Fig. 5 (c).
Therefore, owing to passing through overlap T bending, the counter-force F2 that abutting part 21 bears from overlap T disappears, and spindle unit 20 can not move, and therefore, can be judged to be overlap T is to have the dangerous overlap that comes off.
Like this, spindle unit 20 bears from the counter-force F2 of overlap T and to moving axially, whether the limiter 24 based on spindle unit 20 has come off from the plunger installation portion 13 of main part 10, and even whether residual, also can distinguish is simply good overlap.
As previously discussed, provide a kind of overlap evaluating apparatus of evaluating being formed at the intensity of the overlap in the oil circuit of automatic transmission in present embodiment, it possesses: the main part 10 of tubular; Spindle unit 20, it is by main part 10 supporting and can move vertically, and makes to have distolateral being positioned at outside main part 10 with the abutting part 21 of overlap butt; Bulb stopper 30, it applies the acting force (500gf) of regulation to spindle unit 20, the counter-force of bearing from overlap while pressing overlap with opposing by abutting part 21, bulb stopper 30 is radially connecting main part 10 and arranging in the direction that spindle unit 20 is applied to the acting force of regulation from spindle unit 20, spindle unit 20 is set as following formation, that is: larger and when leaving direction (axially) movement of overlap than the acting force of regulation with counter-force when bearing from overlap, be positioned at that another of main part 10 is distolateral to be arranged from the outstanding mode of main part 10.
According to this formation, when counter-force that the acting force of regulation bears from overlap when pressing overlap is large, spindle unit 20 is held in original position.And when the counter-force of bearing from overlap is larger than the acting force of regulation, spindle unit 20 bears from the counter-force of overlap and moves to another distolateral (leaving the direction of overlap).
Therefore, in the situation that the intensity of overlap enough and not comes off is dangerous, the pressing force that abutting part 21 is pressed overlap becomes large, surpasses the moment of the acting force of regulation in the counter-force of bearing from overlap, and spindle unit 20 moves to the direction of leaving overlap.On the other hand, in the situation that the intensity of overlap is not high, due to will bending when press the overlap midway of overlap by abutting part 21, therefore, spindle unit 20 can not move to the direction of leaving overlap.Thus, based on spindle unit 20, whether to moving axially, just can determine whether it is to have the dangerous overlap that comes off.In addition, now, can not produce and can become the fragment of snotter etc.
In addition, be configured to, in the periphery of plunger receiving portion 23 that is positioned at the spindle unit 20 of main part 10, be provided with the chimeric groove 232 of ball 30b of bulb stopper 30.
According to this formation, by the ball 30b axial movement of restrictive axes parts 20 reliably of bulb stopper 30.
At one of main part 10 distolateral reducing diameter part 11, spindle unit 20 is supported vertically movably, the other end at spindle unit 20, with the outer diameter D 8 identical with main part 10, be provided with from axially and the other end butt of main part 10 and stop up the limiter 24 of the other end side opening of main part 10, spindle unit 20 is set as following formation, that is: make to engage with the otch 13b of main part 10 to the side-prominent spline pin 25 (projection) of main part 10 from limiter 24, the state by main part 10 with spline is supported.
According to this formation, owing to preventing that when pressing overlap by abutting part 21 spindle unit 20 from rotating, therefore, the pressing force that can make to act on overlap is even.
In addition, when spindle unit 20 moves to the direction of leaving overlap, limiter 24 comes off from main part 10, therefore, can grasp reliably spindle unit 20 ground and move.
In addition, be set as following formation, that is: at one of main part 10 distolateral reducing diameter part 11, spindle unit 20 is supported vertically movably via the lining 15 of nylon.
In embodiment, because main part 10 and spindle unit 20 consist of stainless steel, therefore, if lining 15 is not set, when spindle unit 20 moves vertically, the metal of the same race sliding resistance producing of sliding each other becomes large.So, the counter-force of bearing from overlap suitably can not be sent to plunger receiving portion 23 sides of bulb stopper 30 butts, overlap evaluation precision reduces.When being provided with the lining 15 of nylon, due to the resistance force diminishes of bearing, therefore, improve overlap evaluation precision when spindle unit 20 moves vertically.
Abutting part 21 is set as following formation, that is: there is the identical cylindrical shape of total length L diameter of penetrating length direction, in the front of spindle unit 20, be provided with the tabular surface 22a with the axial quadrature of spindle unit, abutting part is fixed in the central authorities of tabular surface 22a by welding.
By abutting part 21 being made as to other parts, thereby, when wearing and tearing occur abutting part 21, only change abutting part.In addition, by cut etc., in the situation that the front end of spindle unit 20 forms abutting part, in order to ensure the intensity of abutting part 21, need processing such as quenchings grade.In contrast, when abutting part 21 is made as to other parts and is fixed by welding, it is cheap that cost of manufacture becomes.
Then, the overlap evaluating apparatus 1A of the second embodiment is described.
In the overlap evaluating apparatus 1A of the second embodiment, thereby use spring S to replace the ball match 30 of the 1st embodiment to limit the axial movement of spindle unit 20.
Therefore, spindle unit 20 possesses the spring abutting part 23A of cylindrical shape at the base end part 22b of axial region 22, to replace above-mentioned plunger receiving portion 23.
This spring abutting part 23A forms with the diameter less than the through hole of main part 10 14, in through hole 14, can move vertically.
And, at the face butt with axial region 22 opposition sides of spring abutting part 23A, there is one end of spring S.
At main part 10 and end 10a reducing diameter part 11 opposition sides, acting force governor motion 50 is screwed into and is installed on through hole 14.
Acting force governor motion 50 possesses: periphery is formed with the axial region 51 of external thread 51a, flange part 52, the adjusting screw 53 of extending from the cardinal extremity of axial region 51 to radial outside.
Axial region 51 has the external diameter mating with the internal diameter of through hole 14, makes the external thread 51a of periphery be screwed into the internal thread 10b of main part 10 and be fixed on main part 10.
At axial region 51, at the front end of spindle unit 20 sides, be provided with than the spring fitting portion 511 of axial region 51 paths.Spring fitting portion 511 has cylindrical shape, and the other end of spring S is installed to embedding outside its periphery.
At axial region 51, at the outer peripheral face that is positioned at the outside cardinal extremity of main part 10, run through the all-round flange part 52 extending to radial outside that is provided with.
Adjusting screw 53 is overlooked as having annular shape, and portion is provided with and makes axial region 51 insert logical opening 53a in the central.Inner peripheral surface at opening 53a is provided with internal thread (not shown).Therefore, adjusting screw 53 is screwed into and is installed on the periphery of axial region 51, and under this state, adjusting screw 53 can moving axially along central shaft X.
In the present embodiment, by regulating the distance L x of adjusting screw 53 and flange part 52, can regulate the length L y of the axial region 51 that is positioned at main part 10, by changing the length L y of this axial region 51, change the axial length L z of spring S, thereby, can regulate the acting force that acts on spindle unit 20 from spring S.
In the present embodiment, with the situation of the 1st embodiment similarly, with the acting force with 500gf, spindle unit 20 is regulated to each length L x, Ly, Lz to the mode of left side (abutting part 21 leaves the direction of main part 10) application of force in figure.
In the periphery that is positioned at the axial region 22 of main part 10 outsides, be hidden in the interior invisible position just above of reducing diameter part 11, be provided with the mark Mk of triangle.
This mark Mk is in order just to confirm that by visual spindle unit 20 bears from the counter-force of overlap T and arranges to axially movable situation.
Action to overlap evaluating apparatus 1A describes.
Fig. 7 is the figure that the evaluation of the overlap T of the cross part in oilhole A and oilhole B is described, (a) being figure spindle unit 20 being described to axially movable situation according to the evaluation of overlap, is (b) figure situation of overlap bending being described according to the evaluation of overlap.
As shown in Fig. 7 (a), the abutting part of spindle unit 20 21 is close to overlap T from the direction of intersecting with overlap T, make abutting part 21 and overlap T butt.
While overlap evaluating apparatus 1A being moved from this state to the direction of utilizing abutting part 21 to press overlap T, on spindle unit 20, effect has the counter-force from overlap T, and the power that the direction that spindle unit is represented to arrow F2 in figure moves works.
Spring S is connected to the spring abutting part 23A of spindle unit 20, and the direction representing to arrow F1 in figure, to spindle unit 20 application of forces, has limited the axial movement of spindle unit 20.
When overlap T has the sufficient intensity that does not come off dangerous, even if pressed by abutting part 21 can bending yet for overlap T.So, because effect on spindle unit 20 is corresponding to acting on the counter-force F2 of the pressing force of overlap T from abutting part 21, therefore, at this counter-force F2 ratio, from spring S, be input to the large moment of directed force F 1 of spindle unit 20, spring S compressed (in the situation of Fig. 7, being compressed to Lz ' from Lz).
Thus, axial region 22 moves to right in figure, and the mark Mk of the periphery of axial region 22 is hidden in the reducing diameter part 11 of main part 10 and becomes and cannot see.
That is, in the situation that overlap T has the dangerous sufficient intensity that do not come off, because spindle unit 20 is to moving axially, mark Mk is hidden in the reducing diameter part 11 of main part 10 and becomes and cannot see, therefore, according to mark, Mk cannot see, and can grasp overlap T is the dangerous overlap that do not come off.
On the other hand, when overlap T does not have enough intensity, as shown in Fig. 7 (b), bending when overlap T is pressed by abutting part 21.
In this case, the counter-force F2 bearing from overlap T than abutting part 21 due to the directed force F 1 from spring S is large, and therefore, spindle unit 20 can be to moving axially.Therefore, the mark Mk of the periphery of axial region 22 can not be hidden in the reducing diameter part 11 of main part 10 and becomes and cannot see.
In addition, in the moment of overlap T bending, the counter-force F2 bearing from overlap T due to abutting part 21 disappears, therefore, situation about disappearing according to its counter-force, also can grasp overlap T is to have the dangerous overlap that comes off.
Like this, in the overlap evaluating apparatus 1A of the second embodiment, spindle unit 20 bears from the counter-force of overlap T and to moving axially, whether based on whether cannot see the mark Mk that is installed on axial region 22, even residual, also can distinguish is simply good overlap.
As previously discussed, provide a kind of overlap evaluating apparatus of evaluating being formed at the intensity of the overlap in the oil circuit of automatic transmission in the second embodiment, it is configured to possesses: the main part 10 of tubular; Spindle unit 20, it is by main part 10 supporting and can move vertically, and makes to have distolateral being positioned at outside main part 10 with the abutting part 21 of overlap butt; Spring S, the acting force of the regulation that it applies spindle unit 20 (500gf), the counter-force of bearing from overlap while pressing overlap with opposing by abutting part 21, spring S is being radially arranged in main part 10 in the direction of the acting force of regulation applying spindle unit 20 from spindle unit 20, in the periphery of spindle unit 20 that is positioned at the outside of main part 10, when the counter-force of bearing from overlap makes greatly spindle unit 20 mobile to axial (moving to the direction of leaving overlap) than the acting force of regulation, in the interior invisible position of the reducing diameter part 11 that is hidden in main part 10, be provided with mark Mk.
According to this formation, when the counter-force of bearing from overlap when pressing overlap at the acting force of regulation is large, spindle unit 20 is held in origin-location.And when the counter-force of bearing from overlap is larger than the acting force of regulation, spindle unit 20 bears from the counter-force of overlap mobile to another distolateral (leaving the direction of overlap), the mark Mk of spindle unit 20 becomes and cannot see.
Therefore, in the situation that the intensity of overlap enough and not comes off is dangerous, the pressing force that abutting part 21 is pressed overlap becomes large, surpasses the moment of the acting force of regulation in the counter-force of bearing from overlap, spindle unit 20 moves to the direction of leaving overlap, and mark Mk becomes and cannot see.On the other hand, in the situation that the intensity of overlap is not high, because the overlap midway of pressing overlap at abutting part 21 is with regard to bending, therefore, spindle unit 20 can not move to the direction of leaving overlap.Therefore, mark Mk still can see.Thus, based on spindle unit 20 mark whether cannot see, can determine whether it is to have the dangerous overlap that comes off.In addition, now, can generation can not become fragment of snotter etc. yet.
