Summary of the Invention

Problems to be Solved by the Invention

[0004] Here, when welding the sensor boss to the exhaust system part, it is necessary to suppress the entry of spatter into the communication passage. Further, in order to improve the measurement accuracy of the sensor attached to the sensor boss, it is necessary to accurately determine the position of the sensor boss. For this reason, when welding the sensor boss disclosed in Patent Document 1 to the exhaust system part, it is conceivable to block the opening of the communication passage of the sensor boss with a boss plug and press the boss plug with a fixing jig to fix the position of the sensor boss.

[0005] However, since the sensor boss of Patent Document 1 is provided inclined with respect to the exhaust system part, there is a risk that the fixing jig interferes with the welding torch during the welding operation, making it impossible to weld, or the welding torch cannot be placed in an appropriate posture, resulting in a deterioration of the welding quality.

[0006] In one aspect of this disclosure, it is desirable to perform the welding well. [Means for solving the problem]

[0007] One aspect of the present disclosure is an in-vehicle component comprising a flow path member, a through hole, and a base. The flow path member forms a fluid flow path. The through hole is a hole that penetrates the flow path member. The base is welded to the outer surface of the flow path member so as to cover a mounting area which is the region surrounding the through hole on the outer surface of the flow path member. The base also comprises a contact surface, a communication passage, a mounting portion, a positioning surface, and an engaged portion. The contact surface contacts the mounting area. The communication passage is a hole that extends through the base from a first opening provided on the contact surface so as to connect to the through hole, to a second opening that is open to the outside of the flow path. The mounting portion is provided near the second opening on the inner surface surrounding the communication passage and is configured to accommodate a measuring component for measuring the fluid passing through the flow path. The positioning surface is formed on the opposite side of the contact surface. The engaged portion is provided on the positioning surface and is configured to engage with a positioning jig used to fix the position of the base when welding the base to the outer surface of the flow channel member.

[0008] With the above configuration, when welding the base to the mounting area of ​​the flow channel member, the position of the base can be fixed by a positioning jig placed on the opposite side of the contact surface with the flow channel member on the base, thereby securing space on the side of the base for welding. As a result, welding can be performed well.

[0009] In one aspect of the present disclosure, the base may further include a mounting surface which is a surface on which the second opening is formed and which is separate from the positioning surface. The section of the passage on which the mounting portion is provided may extend from the second opening along an axis. The axis may extend in a direction that is not parallel to a reference line substantially perpendicular to the through hole.

[0010] According to the above configuration, the measuring component can be suitably attached to the base. One aspect of the present disclosure may further include a base with a side surface and a holding portion. The side surface extends from the edge of the positioning surface toward the contact surface. The holding portion is a portion provided on the side surface that contacts the positioning jig when welding the base to the outer circumferential surface of the flow channel member.

[0011] According to the above configuration, when fixing the position of the base with a positioning jig in order to weld the base to the outer surface of the flow channel member, it is possible to suppress the displacement of the positioning jig relative to the base. In one aspect of this disclosure, the fluid may be exhaust gas. The vehicle component may be configured as an exhaust gas purification device.

[0012] According to the above configuration, interference with welding the base to the exhaust gas purification device can be suppressed. In one aspect of the present disclosure, the method for manufacturing the above-described in-vehicle component may include: positioning a base on the outer circumferential surface of a flow channel member such that the first opening connects to a through hole and the contact surface contacts a mounting area; fixing the position of the base with a positioning jig engaged with an engaged portion of the positioning surface of the base; closing the second opening of the base with a cover member; and welding the base to the outer circumferential surface of the flow channel member.

[0013] According to the above configuration, space can be secured to place welding equipment on the side of the base, allowing for good welding of the base. In addition, it is possible to suppress spatter generated during welding from entering the second opening of the base. [Brief explanation of the drawing]

[0015] Hereinafter, exemplary embodiments of the present disclosure will be described with reference to the drawings. [1. First Embodiment] [(1) Overview] The in-vehicle component of the first embodiment is configured as, for example, an exhaust system component that forms a flow path for exhaust gas from the engine of a vehicle. Specifically, the in-vehicle component is configured as an exhaust gas purification device 1 configured to purify exhaust gas (see FIGS. 1A to 2B). More specifically, the exhaust gas purification device 1 may be a catalytic converter. The in-vehicle component may also be an exhaust pipe, an exhaust manifold, or a muffler. Of course, it is not limited to this, and the in-vehicle component may be a component that forms a flow path for a fluid other than exhaust gas.

[0016] The exhaust gas purification device 1 includes a flow path member 2, which is a plate-like member that forms the exhaust gas flow path 10, and a pedestal 3 for attaching a measurement component 4 for measuring the exhaust gas flowing through the flow path 10 to the exhaust gas purification device 1. The measurement component 4 may be, for example, a sensor for measuring the temperature or oxygen concentration of the exhaust gas, or a differential pressure pipe. The differential pressure pipe is a member that forms a flow path branching from the flow path of the exhaust gas flow path 10, and a sensor for measuring the pressure of the exhaust gas in the flow path 10 is provided at the tip of the differential pressure pipe.

[0017] [(2) Flow path member] The flow path member 2 has a through hole 20 that penetrates the flow path member 2 and communicates the exhaust gas flow path 10 with the external space (see FIG. 1B). The through hole 20 is formed, as an example, in a portion of the flow path member 2 that extends in a substantially planar shape and has a substantially circular shape. Hereinafter, a virtual straight line that is substantially orthogonal to the through hole 20 and passes through the center of the through hole 20 will be referred to as a reference line 20A.

[0018] [(3) Pedestal] The pedestal 3 is a member for attaching the measurement component 4 to the through hole 20 of the flow path member 2 and has a configuration as a sensor boss (see FIGS. 1A to 2B). The pedestal 3 is welded to the outer peripheral surface 21 so as to cover an attachment region 21A, which is a region surrounding the through hole 20 on the outer peripheral surface 21 of the flow path member 2. The attachment region 21A extends in a substantially planar shape as an example. The pedestal 3 includes a contact surface 30, an attachment surface 31, a communication path 32, an attachment portion 33, a positioning surface 34, an engaged portion 35, a side surface 36, and a holding portion 37.

[0019] <Abutting surface> The contact surface 30 is a substantially planar portion on the outer surface of the base 3 that contacts the mounting area 21A of the flow channel member 2 (see Figures 1A-2B). The edge of the contact surface 30 is welded to the mounting area 21A around its entire circumference. A first opening 32A is also formed in the contact surface 30.

[0020] <Mounting surface> The mounting surface 31 is a substantially planar portion on the outer surface of the base 3, and the measuring component 4 is provided thereon (see Figures 1A to 2B). The mounting surface 31 is a separate surface from the positioning surface 34, and as an example, it is inclined with respect to the reference line 20A so that it approaches the reference line 20A of the through hole 20 as it moves away from the flow path member 2. A second opening 32B is also formed on the mounting surface 31.

[0021] <Communication path> The connecting passage 32 is a hole that penetrates the base 3, extending from the first opening 32A to the second opening 32B, and having first and second sections 32C and 32D (see Figures 1A to 2B). The connecting passage 32 also connects the exhaust gas flow path 10 inside the flow path member 2 with the outside of the flow path member 2.

[0022] The first opening 32A is positioned to connect with the through-hole 20 of the flow channel member 2, and the first section 32C extends from the first opening 32A along the reference line 20A. The second section 32D extends along the axis 3A from the second opening 32B, which is open to the outside of the exhaust gas flow path 10, and connects to the end of the first section 32C. The axis 3A is a hypothetical straight line that is approximately perpendicular to the second opening 32B (in other words, the mounting surface 31), and is not parallel to the reference line 20A. That is, the second section 32D is inclined with respect to the direction of the reference line 20A of the through hole 20 of the flow path member 2. The first section 32C and the second section 32D may be connected in a straight line.

[0023] <Mounting part> Mounting portions 33 for attaching measuring components 4 are provided on the inner circumferential surface surrounding the second section 32D of the connecting passage 32, near the second opening 32B (see Figures 1A-2B). The mounting portions 33 may be, for example, screws for fastening the measuring components 4. The mounting portions 33 are provided adjacent to the second opening 32B and surround a cylindrical space extending along the axis 3A. Furthermore, the portion of the second section 32D where the mounting portions 33 are located is enlarged in diameter, and a step is formed at the end of the mounting portions 33 opposite the second opening 32B.

[0024] <Positioning surface> The positioning surface 34 is a substantially planar portion on the outer surface of the base 3, located on the opposite side of the contact surface 30 (see Figures 1A-2B). More specifically, the positioning surface 34 is, for example, adjacent to the mounting surface 31 and located on the opposite side of the first opening 32A. That is, the positioning surface 34 is located substantially opposite the first opening 32A. Furthermore, the positioning surface 34 is inclined with respect to the contact surface 30 so that it approaches the flow channel member 2 as it moves away from the mounting surface 31.

[0025] <Engaged part> The engaged portion 35 is provided on the positioning surface 34 (see Figures 1A and 2B). The engaged portion 35 is configured to engage with a positioning jig 5 used to fix the position of the base 3 when welding the base 3 to the mounting area 21A of the flow path member 2 during the manufacture of the exhaust gas purification device 1 (details will be described later).

[0026] The engaged portion 35 is configured, for example, as a circular hole formed in the positioning surface 34. This makes it easier to manufacture the base 3 compared to when the engaged portion 35 is a rectangular hole. Furthermore, when the engaged portion 35 is circular, it is easier to fit the engaged portion 53 of the positioning jig 5, which will be described later, compared to when the engaged portion 35 is a rectangular hole. Also, the engaged portion 35 is located, for example, approximately in the center of the width direction W on the positioning surface 34, near the end opposite the mounting surface 31. The width direction W refers to the direction perpendicular to the axis 3A.

[0027] <Side view> The side surface 36 is the portion located laterally on the outer surface of the base 3, extending from the edges of the mounting surface 31 and the positioning surface 34 to the contact surface 30 (see Figures 1A-2B). The side surface 36 extends in a way that encircles the base 3.

[0028] <Holding part> The holding portion 37 is provided on the side surface 36 of the base 3 (see Figures 1A to 2B) and comes into contact with the positioning jig 5 when the base 3 is welded to the mounting area 21A of the flow path member 2 during the manufacture of the exhaust gas purification device 1 (details will be described later). In this embodiment, as an example, the holding portion 37 is configured as two areas that extend in a substantially planar manner on the side surface 36. These areas are located on both sides of the mounting surface 31 and the positioning surface 34.

[0029] [(4) Welding process for the base] The manufacturing method of the exhaust gas purification device 1 includes a welding step of welding the base 3 to the flow path member 2 (see Figures 2C to 3B). The welding step includes an arrangement step, a fixing step, a closing step, and a welding step.

[0030] <Placement Steps> In the placement step, the base 3 is placed on the mounting area 21A of the outer circumferential surface 21 of the flow path member 2 (see Figure 2C). At this time, the first opening 32A of the contact surface 30 of the base 3 connects to the through hole 20, and the contact surface 30 contacts the mounting area 21A. As a result, the entire through hole 20 is covered by the base 3, and the exhaust gas flow path 10 inside the flow path member 2 and the space outside the flow path member 2 are connected by the communication passage 32 of the base 3.

[0031] <Fixed step> In the fixing step, which follows the placement step, the position of the base 3, which is placed in the mounting area 21A, is fixed relative to the flow path member 2 by the positioning jig 5 (see Figures 3A and 3B).

[0032] <Positioning jig> The positioning jig 5 comprises a main body 50, two arm sections 51, a positioning section 52, and an engaging section 53 (see Figures 3A and 3B).

[0033] The main body portion 50 is a rod-shaped part, and in this embodiment, it is prism-shaped as an example. The two arm portions 51 are provided near the end face 50A on the outer circumferential surface of the main body portion 50, so as to protrude from the end face 50A. The two arm portions 51 face each other with the end face 50A and the positioning portion 52 in between.

[0034] The positioning portion 52 is a cylindrical part that protrudes from the end face 50A of the main body portion 50. The engaging portion 53 is a projection provided on the tip surface of the positioning portion 52. <Details of the fixed step> In the fixing step, the engaging portion 53 of the positioning portion 52 of the positioning jig 5 engages with the engaged portion 35 of the positioning surface 34 of the base 3 (see Figures 3A and 3B). Specifically, the engagement is achieved when the engaging portion 53 of the positioning jig 5, which is a projection, fits into the engaged portion 35 of the base 3, which is a circular hole. The engaging portion 53 may be fitted into the engaged portion 35 without any gap, or it may be fitted with a slight gap. Alternatively, the engagement may be achieved when the engaging portion 53 catches on the engaged portion 35.

[0035] Furthermore, at this time, the two arm portions 51 of the positioning jig 5 come into contact with the holding portion 37 on the side surface 36 of the base 3. This prevents the positioning jig 5, whose engaging portion 53 is engaged with the engaged portion 35, from rotating around the engaged portion 35. Specifically, the two arm portions 51 each come into contact with the respective regions forming the holding portion 37 on the side surface 36 of the base 3, thereby clamping the base 3 from the side.

[0036] Then, the positioning jig 5, in which the engaging portion 53 engages with the engaged portion 35 and the two arm portions 51 abut against the holding portion 37, presses the base 3 toward the flow path member 2. This fixes the position of the base 3 relative to the flow path member 2.

[0037] <Closing Step> In the closing step, the second opening 32B of the base 3 is closed by the cover member 6 (see Figures 3A and 3B). The cover member 6 covers the entire area of ​​the second opening 32B and, as an example, is positioned to cover substantially the entire area of ​​the mounting surface 31.

[0038] <Welding Steps> In the welding step, the base 3 positioned in the mounting area 21A of the flow channel member 2 is welded (see Figures 3A and 3B). At this time, in the closing step, the second opening 32B of the base 3 is closed by the cover member 6, and in the fixing step, the position of the base 3 relative to the flow channel member 2 is fixed by the positioning jig 5. In the welding step, the welding torch 7 is moved around the base 3, so that the entire circumference of the edge of the contact surface 30 of the base 3 is welded to the mounting area 21A.

[0039] [2. Second Embodiment] The second embodiment differs from the first embodiment in the configuration of the engaged portion 35 of the base 3 and the configuration of the engaged portion 53 of the positioning jig 5 (see Figures 4A to 4D). The differences between the second embodiment and the first embodiment will be described below.

[0040] In the second embodiment, the engaged portion 35 of the base 3 is configured as a cylindrical part that protrudes from the positioning surface 34. The engaged portion 53 of the positioning jig 5 is configured as a round hole that forms a cylindrical space similar to the engaged portion 35.

[0041] Then, in the fixing step, the engaged portion 35 of the base 3 engages with the engaging portion 53 of the positioning jig 5 in the same way as in the first embodiment, by fitting or catching on it.

[0042] [3. Third Embodiment] The third embodiment differs from the first embodiment in the orientation of the positioning surface 34 of the base 3 (see Figures 5A to 5D). Specifically, in the third embodiment, the positioning surface 34 is substantially parallel to the contact surface 30.

[0043] [4. Fourth Embodiment] The fourth embodiment differs from the first embodiment in the configuration of the positioning surface 34 of the base 3 (see Figures 6A to 6D). Specifically, in the fourth embodiment, the positioning surface 34 has first and second regions 34A and 34B that extend in a substantially planar manner. The first and second regions 34A and 34B are located at the first and second ends, respectively, in the width direction W, and the boundary line 34C of the first and second regions 34A and 34B extends in a substantially straight line at approximately the center of the width direction W on the positioning surface 34. Furthermore, the first and second regions 34A and 34B are inclined so as they approach the boundary line 34C that they protrude to the opposite side of the contact surface 30. In addition, an engaging portion 35 similar to that in the first embodiment is formed on the boundary line 34C.

[0044] [5. Fifth Embodiment] The fifth embodiment differs from the first embodiment in the configuration of the engaged portion 35 of the base 3 (see Figures 7A to 7D).

[0045] In the fifth embodiment, the engaged portion 35 has first and second portions 35A and 35B. The first and second portions 35A and 35B are located at both ends in the width direction W of the positioning surface 34 and are formed as elongated notches extending from the positioning surface 34 in the direction of the reference line 20A.

[0046] In other words, the first and second parts 35A and 35B are groove-shaped portions formed on the side surface 36 of the base 3, extending from the positioning surface 34 in the direction of the reference line 20A. The end on the positioning surface 34 side is open, and the opposite end has a bottom surface. The cross-section of the first and second parts 35A and 35B perpendicular to the extension direction is, for example, approximately a semicircle, but this shape is not limited to this and can be determined as appropriate.

[0047] Furthermore, the engaging portion 53 of the positioning jig 5 has two rod-shaped portions that engage with the first and second portions 35A and 35B of the engaged portion 35 of the base 3. Then, in the fixing step, the two rod-shaped portions of the engaging portion 53 of the positioning jig 5 enter the first and second portions 35A and 35B of the engaged portion 35 of the base 3, respectively, thereby engaging the engaged portion 35 and the engaging portion 53.

[0048] [6. Sixth Embodiment] The sixth embodiment differs from the first embodiment in that a drainage channel 38 is provided in the base 3 (see Figures 8A to 8D). The drainage channel 38 is a hole that penetrates the base 3 and extends in a substantially straight line from the bottom of the engaged portion 35 to a position on the side surface 36 of the base 3 opposite the mounting surface 31.

[0049] [7. Effects] (1) According to the above embodiment, in the fixing step of the welding process of the base 3, the position of the base 3 can be fixed by the positioning jig 5 which is located on the opposite side of the contact surface 30 of the base 3. This makes it possible to secure space to position the welding torch 7 on the side of the base 3. Therefore, interference between the positioning jig 5 and the welding torch 7 during welding can be suppressed, preventing welding from becoming impossible or the welding torch 7 from being in an inappropriate position and thus reducing the quality of the weld. As a result, welding can be performed well.

[0050] (2) Furthermore, the positioning surface 34 of the base 3 is formed as a separate surface from the mounting surface 31 on which the second opening 32B is provided, and in the closing step of the welding process of the base 3, the second opening 32B is closed by the cover member 6. This prevents spatter generated during welding from entering the second opening 32B of the base 3.

[0051] (3) Furthermore, the second section 32D (in other words, the axis 3A) of the communication passage 32 of the base 3 on which the mounting portion 33 of the measuring component 4 is provided is inclined with respect to a reference line 20A that is substantially perpendicular to the through hole 20 of the flow channel member 2. Therefore, the measuring component 4 can be suitably attached to the base 3.

[0052] (4) Furthermore, a holding portion 37 is provided on the side surface 36 of the base 3, and in the fixing step of the welding process of the base 3, the base 3 is fixed by the two arm portions 51 of the positioning jig 5 coming into contact with the holding portion 37. For this reason, even if the engaged portion 35 of the base 3 is a circular hole or cylindrical, as in the first to fourth and sixth embodiments, and there is a risk that the positioning jig 5 engaged with the engaged portion 35 will rotate around the engaged portion 35, the displacement of the positioning jig 5 relative to the base 3 can be suppressed.

[0053] [8. Other Embodiments] (1) In the base 3 of the above embodiment, the positioning surface 34 is formed as a separate surface from the mounting surface 31 of the measuring component 4. However, the invention is not limited to this, and the positioning surface 34 and the mounting surface 31 may be the same surface. That is, the area around the second opening 32B of the communication passage 32 may be formed as the positioning surface, and the engaging portion may be provided on the positioning surface.

[0054] (2) In the base 3 of the above embodiment, two substantially planar regions on the side surface 36 form a holding portion 37 that contacts the two arm portions 51 of the positioning jig 5 during the fixing step of the welding process. However, the invention is not limited to this, and two curved or uneven regions on the side surface 36 may be used as the holding portion. Alternatively, two regions on the side surface 36 that have engaged portions (for example, holes or protrusions) may be used as the holding portion, and the two arm portions 51 of the positioning jig 5 may be configured to engage with the engaged portions of these regions, respectively.

[0055] In addition, for example, N regions (where N is a positive integer of 3 or more) on the side surface 36 may be designated as holding portions 37, and in the fixing step of the welding process, the N arm portions 51 of the positioning jig 5 may contact these regions. Alternatively, for example, one wide region on the side surface 36 may be designated as a holding portion 37, and in the fixing step of the welding process, one arm portion 51 of the positioning jig 5 may contact this region to prevent the positioning jig 5 from rotating around the engaged portion 35.

[0056] (3) The positioning jig 5 used in the fixing step of the welding process of the base 3 in the fifth embodiment does not have to be provided with two arm portions 51. Even in this case, since the engaged portion 35 of the base 3 in the fifth embodiment is composed of first and second portions 35A and 35B, it is possible to suppress the rotation of the positioning jig 5 engaged with the engaged portion 35 around the engaged portion 35. Therefore, it is possible to suppress the displacement of the positioning jig 5 relative to the base 3.

[0057] Furthermore, in the first to fourth and sixth embodiments, the engaged portion 35 of the base 3 may have a shape that prevents the positioning jig 5 engaged with the engaged portion 35 from rotating around the engaged portion 35. Specifically, in the first, third, fourth, and sixth embodiments, the engaged portion 35 may be, for example, an elongated hole (e.g., an oval) or a polygonal hole (e.g., a square). In the second embodiment, the engaged portion 35 may be, for example, a prismatic projection. In addition, the positioning jig 5 used in the fixing step of the welding process does not necessarily have two arm portions 51. Even in such cases, it is possible to prevent the position of the positioning jig 5 from shifting relative to the base 3.

[0058] (4) The shape of the base 3 is not limited to those illustrated in the first to sixth embodiments, but can be determined as appropriate. Specifically, for example, the base 3 may have an elongated shape. (5) Multiple functions of one component in the above embodiment may be realized by multiple components, or one function of one component may be realized by multiple components. Also, multiple functions of multiple components may be realized by one component, or one function realized by multiple components may be realized by one component. Furthermore, some of the configurations of the above embodiment may be omitted. Furthermore, at least some of the configurations of the above embodiment may be added to or replaced with the configurations of other above embodiments.
