JP 2005-282680 A

By the way, in the manufacture of the conventional brake fluid pressure control device for a vehicle, there is a case where the caulking punch is eccentric with respect to the mounting hole and the positional deviation occurs, and the assembly parts such as the solenoid valve are caulked uniformly in the mounting hole. It had the problem that it was difficult to fix. If the caulking is biased, the amount of plastic deformation due to caulking is not uniform all around, and the accuracy of caulking is not good.
Note that the above-described problem applies not only to the case where the assembly component is a solenoid valve but also to the case where it is a pump, a reservoir, or a pressure sensor.

  From such a viewpoint, it is an object of the present invention to provide a method of manufacturing a vehicle brake hydraulic pressure control device and a vehicle brake hydraulic pressure control device capable of caulking and fixing assembly parts uniformly in mounting holes. To do.

  The present invention for solving such a problem includes a base body containing a flow path for brake fluid, an assembly part assembled in a mounting hole formed in the base body so as to communicate with the flow path, and the mounting hole Of the valve housing of the assembly part on the outer peripheral surface of the assembly part and the plastic deformation part formed circumferentially on the hole wall of the mounting hole by pressing the peripheral edge of the opening with a cylindrical pressing member A vehicular brake hydraulic pressure control device including a lid portion that is larger than an outer diameter and smaller than an inner diameter of a tip portion of the pressing member and is locked by the plastic deformation portion to close the mounting hole. In the manufacturing method, the mounting part is placed in a state in which a shoulder portion formed at an end portion of the lid part in the assembly part is exposed to the outside of the base rather than the peripheral edge of the opening. An insertion process for inserting the pressure member and the pressing member in a freely aligning manner. In this state, while the inner peripheral portion of the tip portion is guided by the outer peripheral portion of the shoulder portion of the lid portion in the assembly part, the pressing member is moved to a predetermined position where the tip portion contacts the peripheral edge portion of the opening. A moving step for moving, and the peripheral edge of the opening of the mounting hole is pressed downward by the pressing member to form the plastic deformation portion on the hole wall of the mounting hole. A fixing step of fixing the assembly part to the attachment hole by engaging with the lid part of the assembly part.

  In addition, the assembly | attachment component in this invention is a general term for the components assembled | attached to a base | substrate in order to embody a hydraulic circuit, Comprising: At least any one of a solenoid valve, a pump, a reservoir | reserver, and a pressure sensor is contained.

  According to the method for manufacturing the vehicle brake hydraulic pressure control device, the pressing member can be reliably positioned at a predetermined position. That is, the assembly part is assembled in a state in which the shoulder part formed at the end of the lid part is exposed to the outside of the base rather than the peripheral edge part of the opening by the insertion process, and the pressing member is aligned by the movement process. While being supported freely, the inner peripheral part of the tip part is guided by the outer peripheral part of the shoulder part of the lid part in the assembly part, and the tip part is moved to a predetermined position where it abuts the opening peripheral part. The pressing member can be reliably positioned at a predetermined position using the shoulder of the accessory part. Thereby, an assembly | attachment component can be crimped and fixed to a mounting hole uniformly.

  Further, the shoulder portion of the lid portion is formed into an arc surface shape whose outer peripheral portion is chamfered in a round shape or an inclined surface shape whose outer peripheral portion is chamfered, and is a pressing member while being guided by such a shoulder portion in a moving process. May be configured to be moved. With this configuration, when the pressing member is put on the assembly component, the tip end of the pressing member is smoothly guided by the shoulder of the lid portion of the assembly component, and the pressing member is reliably positioned at a predetermined position. Can do. Thereby, an assembly | attachment component can be crimped and fixed to a mounting hole uniformly.

  Moreover, you may comprise so that a caulking state may be managed by measuring the caulking depth on the basis of the non-pressing part which remained without being pressed with the said pressing member. According to such a configuration, since it is possible to measure the caulking depth with reference to the remaining non-pressing portion, based on the caulking depth, for example, a relative value from a predetermined reference value It is possible to appropriately grasp the caulking state that is difficult to grasp from the appearance, and to manage the caulking state.

  In addition, the method for manufacturing a brake fluid pressure control device for a vehicle according to the present invention includes a base body including a flow path for brake fluid, and a set assembled in a mounting hole formed in the base body so as to communicate with the flow path. An attachment part, a recess formed so as to surround the opening of the mounting hole of the base, and a cylindrical pressing member press the peripheral edge of the opening of the recess to form a circumferential shape on the hole wall of the mounting hole. And an inner peripheral wall surrounding the peripheral edge of the opening of the concave portion so that the outer peripheral portion of the distal end portion of the pressing member can be guided toward the peripheral edge of the opening. A brake hydraulic pressure control device for a vehicle formed in a tapered shape that gradually decreases in diameter toward the peripheral edge of the opening, an insertion step of inserting the assembly part into the mounting hole, and the pressing member In a state where it is supported freely, The moving step of moving the pressing member to a predetermined position where the tip end abuts against the opening peripheral edge while guiding the outer peripheral portion of the tip with the inner peripheral wall of the recess, and the opening peripheral edge of the mounting hole By pressing down the mounting hole with the pressing member to form the plastic deformation portion in the hole wall of the mounting hole, and locking the plastic deformation portion to the lid portion of the assembly part, A fixing step of fixing the assembly part to the mounting hole.

  According to the method for manufacturing the vehicle brake hydraulic pressure control device, the pressing member can be reliably positioned at a predetermined position. That is, the assembly part is inserted into the mounting hole by the insertion process, and the distal end part is guided by the inner circumferential wall of the recess while the pressing member is aligned and supported by the movement process. Therefore, the pressing member can be reliably positioned at a predetermined position by using the inner peripheral wall of the recess. Thereby, an assembly | attachment component can be crimped and fixed to a mounting hole uniformly.

  The mounting hole has a bottom, and the opening peripheral edge of the recess is formed flat with respect to the bottom surface of the mounting hole. In the insertion step, the lower end surface of the assembly component is The assembly part is abutted against the bottom surface of the attachment hole, and the assembly part is inserted into the attachment hole. In the fixing step, the lid portion of the assembly part in a state of being abutted against the bottom surface of the attachment hole is the plastic. It is preferable that the assembly part is prevented from coming out of the mounting hole by being locked by the deforming portion.

  According to such a configuration, there is a variation in the magnitude of the caulking load (the pressing force required for forming the plastic deformation portion on the hole wall of the mounting hole) when the assembly component is caulked and fixed to the mounting hole of the base. It becomes difficult to occur. That is, by pressing the opening peripheral edge of the recess, the assembly component is caulked and fixed, but the opening peripheral edge of the recess is formed flat with respect to the bottom surface of the mounting hole, and the assembly component Since the lower end surface is abutted against the bottom surface of the mounting hole, the distance from the bottom surface of the recess to the part where the lid of the assembly part is locked by the plastic deformation part is unlikely to vary, and therefore the caulking load Difficult to occur.

  Moreover, it is good to set it as the structure inserted in the said insertion process in the state which the shoulder part formed in the edge part of the said cover part in an assembly | attachment component is exposed to the outer side of the said opening peripheral part. By setting it as such a structure, a press member can be positioned smoothly. That is, in the moving process, in addition to the movement using the inner peripheral wall of the recess, the pressing member can be moved using the shoulder of the assembly part, and the pressing member can be reliably positioned at a predetermined position. Will be able to. As a result, the assembled parts can be caulked and fixed uniformly in the mounting holes.

Further, the pressing member has a stepped outer periphery of the tip portion, and has a small diameter portion that presses the opening peripheral portion, and a large diameter portion that does not press the opening peripheral portion,
In the fixing step, a non-pressing portion that is not pressed by the large-diameter portion remains in the peripheral edge portion of the opening, and the caulking depth is measured using the remaining non-pressing portion as a reference, thereby performing caulking. It is preferable that the state is managed.

  According to such a configuration, since it is possible to measure the caulking depth with reference to the non-pressing portion remaining at the peripheral edge of the opening, based on the caulking depth, for example, a predetermined reference value By obtaining a relative value from the above, it is possible to appropriately grasp the caulking state that is difficult to grasp from the appearance, and to manage the caulking state.

  Further, the vehicle brake fluid pressure control device of the present invention includes a base body containing a flow path of brake fluid, an assembly part assembled in an attachment hole formed in the base body so as to communicate with the flow path, A brake hydraulic pressure control device for a vehicle, comprising: an opening peripheral portion surrounding the opening of the mounting hole of the base; a pressing portion pressed by a pressing member when the assembly component is fixed; and the assembly A non-pressing portion that is not pressed by the pressing member when the component is fixed, and the caulking depth from the non-pressing portion can be measured based on the non-pressing portion, and the caulking state is managed based on the measurement It is possible.

  According to such a configuration, since it is possible to measure the caulking depth with reference to the non-pressing portion that is not pressed by the pressing member when fixing the assembled part, based on the caulking depth, for example, predetermined By obtaining a relative value from the obtained reference value, it is possible to appropriately grasp the caulking state that is difficult to grasp from the appearance, and to manage the caulking state of the product.

It is characterized by being formed in a taper shape that gradually decreases in diameter from the portion toward the peripheral edge of the opening.

  According to this vehicular brake hydraulic pressure control device, the inner peripheral wall surrounding the opening periphery of the recess is formed in a tapered shape that gradually decreases in diameter from the opening of the recess toward the opening periphery. When fixing the inserted assembly part, for example, while the caulking pressing member is supported in a freely aligning manner, the front end is opened while the outer peripheral portion of the front end is guided by the inner peripheral wall of the recess. A technique of moving the pressing member to a predetermined position in contact with the peripheral edge can be employed. Thereby, the pressing member can be reliably positioned at a predetermined position using the inner peripheral wall of the recess. Thereby, an assembly | attachment component can be crimped and fixed to a mounting hole uniformly.

  The opening peripheral portion includes a pressing portion that is pressed by a pressing member when the assembly component is fixed, and a non-pressing portion that is not pressed by the pressing member when the assembly component is fixed. It is preferable that the caulking depth from the non-pressing portion can be measured with reference to, and the caulking state can be managed based on the measurement.

The insertion position is restricted both in the radial direction and in the vertical direction (depth direction).

  Subsequently, the solenoid valve 2 is fixed by caulking the hole wall of the mounting hole 10A with the insertion position of the solenoid valve 2 as a reference (fixing step). That is, as shown in FIG. 6 (a), the caulking jig E having a bottomed cylindrical shape is moved toward the mounting hole 10A in a state where the caulking jig E is supported on the arm in a freely aligning manner (moving step). Here, since the outer diameter of the end portion 216A of the lid portion 21B of the electromagnetic valve 2 is smaller than the inner diameter of the caulking jig E, the caulking jig E is moved when the caulking jig E is moved. It is possible to adopt a moving method in which the tip end portion of the caulking jig E is moved to a predetermined position in contact with the bottom surface 17 while the inner peripheral portion of the tip end portion 216A is guided by the shoulder portion 216a of the end portion 216A. Accordingly, even if the caulking jig E is moved toward the bottom surface 17 in a state where the axis of the mounting hole 10A and the axis of the caulking jig E are aligned so that they can be guided as described above, This alignment is allowed, the axial center of the caulking jig E is substantially aligned with the axial center of the mounting hole 10A, and the caulking jig E reaches the predetermined position where the tip end abuts the bottom surface 17. It will be moved (refer FIG.6 (c)).

  Thereafter, the tip end portion of the caulking jig E is pressed against the bottom face 17 of the recess 10B while maintaining the state in which the lower end surface of the electromagnetic valve 2 is abutted against the bottom surface 16 of the mounting hole 10A. By pressing the hole wall downward (toward the bottom surface 16), a plastic deformation portion 18 (see FIGS. 4 and 6D) is formed in the hole wall of the mounting hole 10A, and the plastic deformation portion 18 is connected to the solenoid valve. The electromagnetic valve 2 is caulked and fixed in the mounting hole 10A by being locked in a locking groove 214 (see FIG. 4) formed on the outer peripheral surface of No. 2.

  Here, the caulking jig E as a pressing member used in the present embodiment has a bottomed cylindrical shape as described above, and is provided so as to press the bottom surface 17 of the concave portion 10B at its tip. Yes. As shown in FIG. 7 (a), the front end portion of the caulking jig E is directed outward (to the opposite side to the side where the front end surface (lower end surface) E2 is inclined to the axis (not shown) of the mounting hole 10A. It is formed on a tapered surface in the direction of arrow G (the same direction as the normal to the tip surface E2), and is angled so that the load toward the axis of the mounting hole 10A is reduced. As shown in FIG. 7B, the taper angle θ of the distal end surface E2 is greater than 0 ° and less than 10 ° with respect to the bottom surface 17 (or a horizontal plane perpendicular to the axis of the mounting hole 10A (not shown)). It is preferable that it is in the range of 3 ° to 5 °. When the taper angle θ of the distal end surface E2 is 0 ° or less, a load easily acts in the direction toward the axis of the mounting hole 10A when pressed, and a large caulking load is generated around the locking groove 214 of the solenoid valve 2. Specifically, it is not preferable because it is easily applied to the upper lid 216. When the taper angle θ of the tip surface E2 exceeds 10 °, the load in the direction toward the axial center of the mounting hole 10A is reduced when pressed, and the electromagnetic valve 2 is not easily caulked and fixed to the mounting hole 10A. If the solenoid valve 2 is not properly caulked and fixed in the mounting hole 10A, the brake fluid may leak and the sealing performance may be impaired. According to the research results of the present inventors, the taper angle θ is more preferably in the range of 3 ° to 5 °, and the electromagnetic valve 2 is mounted on the base body with a small caulking load while ensuring the fixing strength of the electromagnetic valve 2. It is possible to perform caulking and fixing to one mounting hole 10A.

  Thus, the solenoid valve 2 is held in the mounting hole 10A so as not to be pulled out by pressing the bottom surface 17 of the recess 10B toward the bottom surface 16 of the mounting hole 10A by the caulking jig E to form the plastic deformation portion 18. At the same time, it is sealed in a liquid-tight manner by radial residual stress in the plastic deformation portion 18. In the present embodiment, the outer peripheral surface of the lower end portion of the electromagnetic valve 2 is brought into close contact with the inner peripheral surface of the contact portion 11 of the mounting hole 10A, and the entire lower end surface of the electromagnetic valve 2 is set to the bottom surface of the mounting hole 10A. 16 by restricting the insertion position of the electromagnetic valve 2 by striking the hole 16 and caulking the hole wall of the holding portion 14 of the mounting hole 10A that does not contribute to the positioning of the electromagnetic valve 2 while maintaining this insertion position. Therefore, when the solenoid valve 2 is fixed, it is difficult for the solenoid valve 2 to tilt.

  The fixing process will be described in more detail with reference to FIG. First, as shown to Fig.7 (a), the front end surface E2 of the crimping jig | tool E is made to contact | abut to the inner periphery of the bottom face 17 of the recessed part 10B. The outer diameter of the upper lid 216 of the electromagnetic valve 2 is formed smaller than the inner diameter of the front end portion of the caulking jig E, and the shoulder portion 216a of the upper lid 216 is rounded and chamfered. Can be positioned smoothly. That is, when the caulking jig E is put on the electromagnetic valve 2, the lower end portion of the caulking jig E is guided by the shoulder portion 216a, so that the entire circumference of the lower end portion of the caulking jig E is surely placed on the bottom surface 17 of the recess 10B. It can be made to contact.

  Next, a downward caulking load is applied to the caulking jig E (“a” → “b” in the graph shown in FIG. 8), and as shown in FIG. Is reduced to the bottom surface 17 of the recess 10B. Since a gap is formed between the inner peripheral surface of the holding portion 14 of the mounting hole 10A and the outer peripheral surface of the upper cover 216 of the solenoid valve 2 (see FIG. 7A), the front end surface of the caulking jig E When E2 is reduced to the bottom surface 17 of the recess 10B, the hole wall in the holding portion 14 of the mounting hole 10A is plastically deformed (plastic flow) toward the upper lid 216 of the electromagnetic valve 2, and the holding portion 14 (see FIG. 3) comes into close contact with the outer peripheral surface of the upper cover 216 of the solenoid valve 2. Incidentally, since a gap is formed between the inner peripheral surface of the holding portion 14 of the mounting hole 10A and the outer peripheral surface of the upper cover 216 of the solenoid valve 2, the hole wall of the mounting hole 10A is plastically deformed with a small caulking load. Can do.

  When the caulking load is increased (“b” → “c” in the graph shown in FIG. 8), as shown in FIG. 7 (d), the tip end surface E2 of the caulking jig E is reduced to a deeper depth. Along with this, the hole wall of the mounting hole 10A protrudes to the upper side of the lower lid 215 of the electromagnetic valve 2 and presses the boundary portion 217 between the lower lid 215 and the locking groove 214 over the entire circumference. At this time, the electromagnetic valve 2 is locked so as not to be pulled out by the plastic deformation portion 18, and the holding portion 14 of the mounting hole 10 </ b> A and the lower lid 215 of the electromagnetic valve 2 are caused by the radial residual stress in the plastic deformation portion 18. Is sealed.

  When the caulking load is further increased (“c” → “d” in the graph shown in FIG. 8), as shown in FIG. 7E, further plastic deformation (plastic flow) occurs in the hole wall of the mounting hole 10A. ) Occurs, and the plastic deformation portion 18 formed in the hole wall of the mounting hole 10 </ b> A enters the locking groove 214 of the electromagnetic valve 2.

  If the caulking load is further increased (“d” → “e” in the graph shown in FIG. 8), the entire locking groove 214 of the electromagnetic valve 2 is plastically deformed in the mounting hole 10A, although illustration is omitted. It will be filled by the part 18. As described above, in the vehicle brake hydraulic pressure control device U, if the caulking load and the stroke of the caulking jig E are managed so as to fall within the range of “c” to “e” shown in the graph of FIG. The site can be sealed.

  Here, as shown in FIG. 7 (f), the non-pressing portion 17 ′ that is not pressed by the caulking jig E remains on the bottom surface 17 that becomes the opening peripheral portion of the recess 10 </ b> B. The non-pressing portion 17 ′ is adjacent to the caulking portion C 1 and can be used as a reference surface when measuring the caulking depth h. That is, the caulking depth h of the caulking portion C1 can be measured using the non-pressing portion 17 'as a reference plane. Accordingly, it is possible to appropriately grasp the caulking state that is difficult to grasp from the appearance, for example, by obtaining a relative value from a predetermined reference value based on the caulking depth h. It is possible to manage the caulking state.

  Before or after the normally open type electromagnetic valve 2 is assembled to the base 1, as shown in FIG. 1, the normally closed type electromagnetic valve 3, the reservoir 4, the pump 5, the pressure sensor 6, the motor 7, etc. When the housing 9 is further assembled so as to cover the electromagnetic valves 2 and 3, the vehicle brake hydraulic pressure control device U is completed.

  According to the method for manufacturing the vehicle brake hydraulic pressure control device U described above, the caulking jig E can be reliably positioned at a predetermined position. That is, the electromagnetic valve 2 is assembled in a state in which the shoulder portion 216a formed at the end portion 216A of the lid portion 21B is exposed to the outside of the base body 1 from the bottom surface 17 by the insertion step, and is caulked by the movement step. In a state where the tool E is supported in a freely aligning manner, the front end portion of the caulking jig E is guided by the outer peripheral portion of the shoulder portion 216a of the solenoid valve 2 while the front end portion of the caulking jig E is the bottom surface 17. Therefore, the crimping jig E can be reliably positioned at a predetermined position by using the shoulder portion 216a of the electromagnetic valve 2. Thereby, the solenoid valve 2 can be caulked and fixed uniformly in the mounting hole.

  Further, since the shoulder portion 216a of the lid portion 21B is formed in an arcuate shape whose outer peripheral portion is rounded and chamfered, when the caulking jig E is put on the electromagnetic valve 2, the tip end portion of the caulking jig E becomes the electromagnetic valve. 2 is smoothly guided by the shoulder portion 216a of the lid portion 21B, and the tip end portion of the caulking jig E can be reliably positioned at a predetermined position. Thereby, the solenoid valve 2 can be caulked and fixed uniformly in the mounting hole 10A.

  The mounting hole 10A is bottomed, and the bottom surface 17 of the recess 10B is formed flat with reference to the bottom surface 16 of the mounting hole 10A. In the insertion process, the lower end surface of the electromagnetic valve 2 is the bottom surface 16 of the mounting hole 10A. The electromagnetic valve 2 is inserted into the mounting hole 10A, and in the fixing step, the lid portion 12B of the electromagnetic valve 2 in the state of being pressed against the bottom surface 16 of the mounting hole 10A is locked by the plastic deformation portion 18. As a result, the solenoid valve 2 is prevented from coming out of the mounting hole 10A. Therefore, when caulking and fixing, the caulking load (the pressing force required for forming the plastic deformation portion 18 on the hole wall of the mounting hole 10A) is achieved. Variations in the size of are less likely to occur. That is, the bottom surface 17 of the recess 10B is formed flat with respect to the bottom surface 16 of the mounting hole 10A, and the bottom surface of the electromagnetic valve 2 is abutted against the bottom surface 16 of the mounting hole 10A. Therefore, it is difficult for the distance from the lid portion 12B of the solenoid valve 2 to the portion where the lid portion 12B of the solenoid valve 2 is locked by the plastic deformation portion 18 to occur, and accordingly, the caulking load is also less likely to vary. Thereby, the solenoid valve 2 can be caulked and fixed uniformly in the mounting hole 10A.

  In particular, in the present embodiment, the mounting hole 10A and the recess 10B are integrally formed with the same drilling tool D, so that the variation in the depth of the mounting hole 10A becomes extremely small, and the solenoid valve starts from the bottom surface 17 of the recess 10B. The variation in the distance to the two locking grooves 214 depends only on the manufacturing accuracy of the electromagnetic valve 2. That is, the variation in the distance from the bottom surface 17 of the recess 10B to the locking groove 214 of the electromagnetic valve 2 is extremely small, and therefore the variation in the caulking load is also extremely small. Thereby, the solenoid valve 2 can be caulked and fixed uniformly in the mounting hole 10A.

(Second Embodiment)
FIGS. 9A and 9B are cross-sectional views for explaining a fixing process of the method for manufacturing the vehicle brake hydraulic pressure control device according to the second embodiment of the present invention.
In the present embodiment, an example in which the normally closed electromagnetic valve 3 is attached to the base body 1 as an assembly part is shown. The base body 1 is formed with a mounting hole 10A into which the electromagnetic valve 3 is inserted. The mounting hole 10A has a depth that allows the lid portion 21B of the electromagnetic valve 3 to be accommodated.

  A concave portion 10B is formed at the opening edge of the mounting hole 10A, and the concave portion 10B is formed in a tapered shape in which the inner peripheral wall 10b is gradually reduced in diameter toward the bottom surface 10c serving as the peripheral edge portion of the opening. In the present embodiment, the outer peripheral portion E3 (the outer peripheral corner portion of the front end portion) of the caulking jig E is guided and lowered by the inner peripheral wall 10b, as shown in FIG. The diameter dimension and the inclination angle of the inner peripheral wall 10b are set so that the front end surface E2 is positioned at a predetermined position on the bottom surface 10c.

When the electromagnetic valve 3 is inserted into the mounting hole 10A through the insertion process, the electromagnetic valve 3 is accommodated in a state in which the lid portion 21B fits in the mounting hole 10A as described above. From this state, when the caulking jig E is moved toward the mounting hole 10A by the moving process, the outer peripheral portion E3 of the tip end portion of the caulking jig E is guided by being brought into contact with the inner peripheral wall 10b of the concave portion 10B, and is caulked. The tip of the tool E is positioned at a predetermined position on the bottom surface 10c while descending along the inner peripheral wall 10b. That is, it is possible to adopt a moving method in which the tip surface E2 of the caulking jig E is moved to a predetermined position on the bottom surface 10c by using the tapered shape of the inner peripheral wall 10b.
Accordingly, even if the caulking jig E is moved toward the bottom surface 10c in a state where the axis of the mounting hole 10A and the axis of the caulking jig E are shifted as much as possible as described above. This alignment is allowed, and the axial center of the caulking jig E is substantially aligned with the axial center of the mounting hole 10A, and the predetermined position where the tip of the caulking jig E contacts the bottom surface 10c. (See FIG. 9B).
Thereby, the crimping jig | tool E can be reliably positioned in a predetermined position using the inner peripheral wall 10b of the recessed part 10B, and the solenoid valve 3 can be crimped and fixed uniformly to the mounting hole 10A.

(Third embodiment)
FIGS. 10A and 10B are cross-sectional views for explaining a fixing process of the method for manufacturing the vehicle brake hydraulic pressure control device according to the third embodiment of the present invention.
This embodiment differs from the second embodiment in that the outer periphery of the tip E1 of the caulking jig E has a stepped shape and is not pressed by the tip E1 (FIG. 10B). Is a point configured to remain on the bottom surface 10c as the peripheral edge of the opening after caulking.

The opening edge of the mounting hole 10A, and a recess 10B is formed, the recessed portion 10B, as shown in FIG. 11 (a), the upper portion 10b ₁ of the inner peripheral wall 10b is, the bottom surface 10c of the opening edge It is formed in a tapered shape that gradually decreases in diameter. The lower 10b ₂ of the inner peripheral wall 10b is formed vertically shape. In other words, the recess 10B has an upper 10b ₁ side is the inner peripheral wall 10b, and is configured with an inclined surface gradually diverging toward the opening of the recess 10B (tapered surface).

The clamping jig E is, as described above, and the outer periphery of the tip end portion E1 is a stepped shape, the tip portion E1 includes a small diameter portion E1 ₁ for pressing the bottom surface 10c of recessed portion 10B to the caulking at the bottom surface to the caulking at 10c and a large-diameter portion E1 ₂ that does not press the. Incidentally, the small diameter portion E1 ₁ of the distal end surface (lower end surface) E2 is similar to that described in the embodiment, the load towards the axis of the mounting hole 10A are the least a tapered surface.
The large diameter portion E1 ₂ has its outer peripheral portion E3 is, are the inner peripheral wall 10b vertically shape along the bottom 10b ₂ of, as shown in FIG. 11 (b), the small diameter portion E1 ₁ is to the bottom surface 10c to the caulking at Thus, the moving direction (pressing direction) of the tip E1 is guided so as to press in the vertical direction. Here, the step portion E4 (see FIG. 11 (a)) of the small diameter portion E1 ₁ and a large diameter portion E1 _2, upon aligning of the clamping jig E (when moving step), the upper portion 10b ₁ of the inner peripheral wall 10b the small diameter portion E1 ₁ functions as relief portion of the order not to abut the. In other words, at the time of aligning the clamping jig E, it is adapted to guide the distal end portion E1 abuts the top 10b ₁ of the large-diameter portion E1 ₂ of the lower end corner portions E3 'the inner peripheral wall 10b. Note that the corner E3 ′ is chamfered in an arc shape, thereby realizing smooth alignment of the tip E1.

Incidentally, as shown in FIG. 11 (b), so that sufficient plastic deformation portion 18 is formed to secure the solenoid valve 3 into the hole wall of the mounting hole 10A, a small diameter portion E1 ₁ presses the bottom surface 10c in the state, the large diameter portion E1 ₂ of the distal end portion E1 is not contact with the bottom surface 10c, the non-pressing portion 10c 'is adapted to remain in the bottom 10c. That is, the small diameter portion E1 _1, as the non-pressing portion 10c 'remains, and is formed to have a predetermined crimping length.

In the caulking using such clamping jig E, when aligning the clamping jig E (when moving step), the upper portion 10b ₁ of the large-diameter portion E1 ₂ of the lower end corner portions E3 'is an inner peripheral wall 10b contacts are tip E1 is aligning, as shown in FIG. 11 (a), the outer peripheral portion E3 of the large-diameter portion E1 ₂ (corner E3 ') are in a state along the bottom 10b ₂ of the inner peripheral wall 10b is , the small diameter portion E1 ₁ of the distal end portion E1 is positioned at a predetermined position of the bottom surface 10c.

Then, as shown in FIG. 11 (b), the small diameter portion E1 ₁ of the distal end portion E1 of the clamping jig E is, to form a plastically deformed portion 18 presses the bottom surface 10c of recessed portion 10B toward the bottom of the mounting hole 10A Thus, the solenoid valve 3 is fixed to the mounting hole 10A so as not to be pulled out.
At this time, the distal end portion E1 of the clamping jig E is, the outer peripheral portion E3 of the large-diameter portion E1 ₂ is guided along the vertical surface of the lower 10b ₂ of the inner peripheral wall 10b, it presses the bottom face 10c in the vertical direction. Thereby, the plastic deformation part 18 sufficient to fix the solenoid valve 3 to the hole wall of the mounting hole 10A is suitably formed.

  As shown in FIG. 11C, when the electromagnetic valve 3 is caulked and fixed, the non-pressing portion 10c 'remains on the bottom surface 10c of the recess 11B. The non-pressing portion 10c 'is adjacent to the caulking portion C1, and can be used as a reference surface when measuring the caulking depth h. That is, the caulking depth h of the caulking portion C1 can be measured using the non-pressing portion 10c 'as a reference plane.

  According to such a configuration, it is possible to measure the caulking depth h of the caulking portion C1 based on the non-pressing portion 10c ′ that is not pressed by the caulking jig E when the electromagnetic valve 3 is fixed. Based on the length h, for example, by obtaining a relative value from a predetermined reference value, it is possible to appropriately grasp a caulking state that is difficult to grasp from the appearance, and manage the caulking state Can do.
