JP-A-7-51980

  In view of the above problems, there is a need for a torque converter cutting device that can suppress the generation of chips and the leakage of hydraulic oil remaining inside when cutting the outer wall of the torque converter. .

  A characteristic configuration of a cutting device for cutting an outer wall of a torque converter according to the present invention includes a fixing portion that fixes the torque converter, a fixing base that supports the torque converter from below, and a rotation of the fixing base. A rotating mechanism that supports the cutting blade so as to face the outer wall of the torque converter fixed to the fixed base, and the cutting blade that moves the cutting blade along the radial direction of the rotational axis of the fixed base A moving mechanism, and the fixed base fixes the torque converter such that the rotational axis of the torque converter and the rotational axis of the fixed base are coaxial, and the rotational axis of the fixed base is Arranged along the vertical direction, the cutting blade is a disk-shaped rotating blade that rotates according to the rotation of the outer wall in a state of being pressed against the outer wall by the cutting blade moving mechanism. Located in.

According to the above characteristic configuration, the fixed base can be fixed from below such that the rotational axis of the fixed base arranged along the vertical direction and the rotational axis of the torque converter are coaxial. Then, the torque converter is rotated around its rotational axis, and the cutting blade is moved along its radial direction and pressed against the outer wall, so that the cylindrical peripheral wall portion covering the radially outer side of the torque converter is cut. Can do. Therefore, even after cutting, the portion of the outer wall fixed to the fixing portion can be shaped to open upward, and the remaining hydraulic oil can be retained inside.
Therefore, when the outer wall is cut, it is possible to suppress the hydraulic oil remaining inside the torque converter from leaking to the outside, and workability and safety can be improved.
In addition, since the disk-shaped rotary blade that rotates according to the rotation of the outer wall moves in the radial direction and is pressed against the outer wall, when the outer wall rotates, the cutting edge of the cutting blade moves the upper wall member up and down by plastic deformation. You can cut into the outer wall by gradually biting into the outer wall. At this time, since the cutting blade rotates according to the rotation of the outer wall, it is possible to suppress generation of chips such as cutting. For this reason, it can suppress that a chip mixes into the inside of a torque converter from a cut. Therefore, when the internal state of the torque converter is confirmed after cutting, it can be suppressed that it is impossible to tell whether the internal metal piece is mixed when cutting or whether it is mixed before cutting.

  Here, it is preferable that the torque converter includes a connecting portion for connecting to the internal combustion engine, and the fixing portion fixes the connecting portion to the fixing base.

  The opening of the outer wall is normally provided on the side connected to the wheel in the direction of the rotation axis, and is not provided on the side connected to the internal combustion engine. According to said structure, since the connection part for connecting with an internal combustion engine is fixed to a fixed base, it can fix to a fixed base with the opening part of an outer wall facing up. Therefore, it can suppress that the hydraulic oil which remained in the outer wall leaks outside from an opening part. Moreover, it is possible to efficiently fix the fixed portion to the fixing base by effectively using the connecting portion. Since it is a connection part for connection with an internal combustion engine, a fixed strength can be ensured.

  Here, the fixing portion includes a connecting member attached to the connecting portion, and a fixing mechanism for fixing the connecting member to the fixing base, and the connecting member is attached to the connecting portion, A rod-like extension part extending from the connecting part to the fixed base side, and a large diameter part formed on the fixed base side than the extension part and having a larger diameter than the extension part, The fixing base includes an upper member and a lower member that face each other in the vertical direction, and the fixing mechanism vertically fixes the fixing space formed in a facing portion between the upper member and the lower member, and the upper member. A through hole penetrating in a direction, and when the extension member passes through the through hole and the large diameter portion is accommodated in the fixed space, the connection member is fixed to the fixed base. Is preferred.

According to this configuration, since the connecting member is attached to the connecting portion for connecting with the internal combustion engine, the connecting member and the torque converter can be reliably coupled.
Further, the extending portion of the connecting member passes through the through hole provided in the upper member, and the large diameter portion of the connecting member is accommodated in a fixed space formed in the facing portion between the upper member and the lower member. Therefore, the large-diameter portion can be embedded in an anchor shape inside the fixed base, and the fixing of the connecting member to the fixed base can be ensured.

  Here, the through-hole includes a narrow portion that is narrower than the large-diameter portion and wider than the extending portion on the circumferential first direction side, which is one side in the circumferential direction of the fixed base, A wide portion through which the large-diameter portion can be inserted on the second circumferential direction side, which is the other side of the circumferential direction, is formed at a position where the narrow portion overlaps the fixed space when viewed in the vertical direction, At least a part of the wide portion is formed at a position that does not overlap the fixed space when viewed in the vertical direction, and the fixed base is the upper member and the lower member in a region that overlaps the through hole when viewed in the vertical direction. Between the separated state in which the distance between the large diameter portions is larger than the vertical length of the large diameter portion and the approach state in which the intervals are narrower than the vertical length of the large diameter portion. It is preferable that the configuration is changeable.

  According to such a structure, a large diameter part can be inserted in a wide part from upper direction in the state which attached the connection member to the torque converter. And if the space | interval which an upper member and a lower member oppose is made into the separation | spacing state, a large diameter part can be inserted to the position between an upper member and a lower member. Then, with the large diameter portion disposed between the upper member and the lower member, the extension portion is slid in the circumferential direction from the wide portion to the narrow portion, and the large diameter portion is fixed in a vertical direction. It can be moved to a position where the entire space overlaps. And if a space | interval is made into an approach state, a large diameter part can be accommodated and fixed in fixed space. Thus, the large diameter portion can be efficiently accommodated in the fixed space. Further, the fixed state can be visually recognized from the outside by the approach or separation between the upper member and the lower member.

  Here, it is preferable that the fixing base includes a guide mechanism that guides the lower member to be movable in a vertical direction, and a biasing mechanism that biases the lower member upward.

  According to such a configuration, the large-diameter portion is accommodated in the fixed space by biasing the opposing distance between the upper member and the lower member in the approaching state, so that the large-diameter portion can be easily fixed in the fixed space. Can be fixed. Moreover, a space | interval can be automatically expanded by inserting a large diameter part in a wide part and pressing from upper direction. Therefore, the torque converter can be fixed more efficiently.

  Here, it is preferable that the through hole is formed so that the wide portion is positioned on the rotation direction side of the fixed base with respect to the narrow portion.

  According to this structure, it can suppress that a connection member moves to a wide part during rotation of a torque converter. Accordingly, it is possible to suppress the connection member from coming out of the wide portion during rotation and releasing the torque converter from being fixed.

  Here, it is preferable that the cutting blade moving mechanism further includes a vertical adjustment mechanism that adjusts the position of the cutting blade in the vertical direction.

  According to this configuration, the vertical position of the cutting blade can be adjusted according to the shape of the torque converter.

  Here, the cutting blade moving mechanism is a screw dedicated to be rotatable around the rotational axis arranged along the radial direction of the rotational axis of the fixed base, and a region less than half of the circumferential direction of the screw dedicated. A meshing female screw member, a presser member that is disposed so as to face the female screw member across the screw rod, and that has a contact surface in contact with the outer peripheral surface of the screw rod; and a support member that supports the cutting blade; The connecting member that connects the support member to the female screw member, the female screw member is moved between a meshing state in which the female screw member is engaged with the screw rod and a separated state in which the female screw member is separated from the screw rod. And a separation mechanism.

  When the torque converter is detached from the fixed base, it is necessary to move the cutting blade in a direction away from the fixed base for workability and safety. According to said structure, a cutting blade can be freely moved irrespective of a feed screw mechanism by making a female screw member into the separation state which left | separated from the screw rod with the separation mechanism. Therefore, the cutting blade can be smoothly moved when the torque converter is attached and detached, and workability and safety can be improved.

An embodiment of a cutting device 1 (hereinafter referred to as a cutting device 1) of a torque converter 70 according to the present invention will be described with reference to the drawings.
FIG. 1 is a cross-sectional view of the cutting device 1 with the torque converter 70 attached, cut along a plane including the rotation axis AX of the fixed base, and FIG. 2 does not have the torque converter 70 attached. It is the figure which looked at the cutting device 1 of the state from upper direction. In the present application, the upper means the upper side in the vertical direction Z, and the lower means the lower side in the vertical direction Z.
As shown in these drawings, the cutting device 1 is a device for cutting the outer wall 71 of the torque converter 70. The cutting device 1 includes a fixed base 30 that fixes the torque converter 70, a rotating mechanism 5 that rotates the fixed base 30, and a cutting blade moving mechanism 80 that moves the cutting blade 90.

The fixing base 30 includes a fixing portion 31 that fixes the torque converter 70 and supports the torque converter 70 from below.
The cutting blade moving mechanism 80 supports the cutting blade 90 so as to face the outer wall 71 (circumferential wall 72) of the torque converter 70 fixed to the fixed base 30, and the cutting blade 90 has a diameter of the rotational axis AX of the fixed base 30. Move along the direction.
The fixed base 30 fixes the torque converter 70 so that the rotational axis AC of the torque converter 70 and the rotational axis AX of the fixed base 30 are coaxial.
The rotation axis AX of the fixed base 30 is arranged along the vertical direction Z.
The cutting blade 90 is a disk-shaped rotating blade that rotates according to the rotation of the outer wall 71 in a state where the cutting blade 90 is pressed against the outer wall 71 (the peripheral wall 72) by the cutting blade moving mechanism 80.
Hereinafter, each part of the cutting device 1 which concerns on this embodiment is demonstrated in detail.

1. Torque converter 70
The torque converter 70 is a power transmission device that is attached to a vehicle drive device and transmits the rotational driving force of the internal combustion engine to a wheel side such as a transmission via hydraulic oil filled therein. In the present embodiment, the torque converter 70 is removed from the drive device for cutting by the cutting device 1.

<Schematic Configuration of Torque Converter 70>
As shown in FIG. 3, the torque converter 70 includes a pump impeller 23 as an input side rotating member connected to the internal combustion engine side and a turbine runner as an output side rotating member connected to the wheel side. 24, a stator 25 provided between them and provided with a one-way clutch 76, and an outer wall 71 as a case member for accommodating them. In the example of the torque converter 70 shown in FIG. 3, the lockup clutch 26 and the damper 27 are also housed inside the outer wall 71.
The outer wall 71 is configured to rotate integrally with the pump impeller 23 and includes a connecting portion 22 for connecting to the internal combustion engine. The outer wall 71 includes a communication hole 75 into which an output shaft (not shown) connected to the turbine runner 24 is inserted. The output shaft is connected to the wheels via a transmission or the like.
When attached to the vehicle drive device, the torque converter 70 transmits the driving force between the drive-side pump impeller 23 and the driven-side turbine runner 24 via hydraulic oil filled in the outer wall 71. I do. Thereby, the rotational driving force of the internal combustion engine is transmitted to the wheel side.

<Leakage of hydraulic oil>
The outer wall 71 of the torque converter 70 is normally open on one side in the axial direction SC for supplying and discharging hydraulic oil to the inside. Since the fixed base 30 can be fixed from below so that the rotational axis AX of the fixed base 30 arranged along the vertical direction Z and the rotational axis AC of the torque converter 70 are coaxial, the outer wall 71 can be fixed. Can be fixed with the opening of the upper side facing upward. Therefore, it can suppress that the hydraulic oil which remained in the outer wall 71 leaks outside from an opening part.

Specifically, the outer wall 71 has a cylindrical peripheral wall 72 that covers a radially outer portion of the torque converter 70 in the rotational axis AC of the torque converter 70 and a side (shaft shaft) connected to the internal combustion engine in the axial direction SC. A disk-shaped first side wall 73 covering the one-direction SC1 side) and an annular second side wall 74 covering the side connected to the wheel in the axial direction SC (referred to as the second axial direction SC2 side). I have.

However, the first side wall 73 is not provided with a communication hole for inserting a shaft or an oil passage.

  That is, the outer wall 71 opens toward the second axial direction SC2 (wheel side) at the communication hole 75 in order to insert the output shaft and the stator support shaft and supply and discharge hydraulic fluid. Therefore, the hydraulic oil remaining in the outer wall 71 in a state where it is removed from the vehicle drive device may leak out from the communication hole 75 on the second axial direction SC2 side. On the other hand, since the first axial direction SC1 side (internal combustion engine side) of the outer wall 71 is covered with the disk-shaped first side wall 73, the possibility of hydraulic oil leaking from the first axial direction SC1 side is low.

<Fixing direction of torque converter 70>
In the present embodiment, in order to prevent the remaining hydraulic oil from leaking out from the torque converter 70, the fixed base 30 is configured such that the second axial direction SC2 side (wheel side) of the torque converter 70 is on the upper side and the first shaft is on the upper side. The torque converter 70 is fixed so that the direction SC1 side (internal combustion engine side) is on the lower side.
By fixing in this direction, the remaining hydraulic oil accumulates on the first side wall 73 side in the outer wall 71, so even if the peripheral wall 72 is cut by the cutting blade 90, the hydraulic oil leaks to the outside. Can be suppressed.
In addition, by fixing in this direction, the torque converter 70 can be efficiently fixed to the fixed base 30 by using the connecting portion 22 that will be positioned below the torque converter 70.

The lower end of the spring 59 is pressed by a fixing bolt 60 fastened to the lower end of the guide shaft 58. The upper end portion of the spring 59 is pressed by the lower end portion of the guide sleeve 57. Since the guide shaft 58 is fixed to the upper member 33 and the position of the fixing bolt 60 in the vertical direction Z does not change, the guide sleeve 57 and the lower member 34 are urged upward by the spring 59.
In this embodiment, the guide mechanism 55 and the urging mechanism 56 are provided at a plurality of locations (three locations in this example) along the circumferential direction, as shown in FIG.

  By this urging mechanism 56, the vertical interval W can be automatically brought into the close state, and the large-diameter portion 52 can be accommodated in the fixed space 46. Moreover, the vertical space | interval W can be expanded by inserting the large diameter part 52 in the wide part 49, and pressing from upper direction. In addition, it is preferable that the pressing force that the urging mechanism 56 pushes the lower member 34 upward is set to be larger than the weight of the lower member 34 and smaller than the weight of the lower member 34 and the torque converter 70. In this way, the vertical distance W can be increased by the weight of the torque converter 70 simply by inserting the large diameter portion 52 into the wide portion 49.
