Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a change guide plate positioning jig when the change guide plate is attached to a mission case.

[0002]

[Prior Art]

 Generally, in a manual transmission for an automobile, a shift operation of a shift lever by a driver is transmitted to a mission mechanism via a control rod arranged in a mission case to perform a predetermined shift operation. In this case, in order to obtain a reliable gear shift operation and a good feeling of operation without malfunctioning, the selector provided on the control rod is fixed to the mission case side and the guide groove of the shape corresponding to the shift pattern is provided. The change guide plate is provided for guiding (see, for example, Japanese Patent Laid-Open No. 56-42282).

On the other hand, the function of such a change guide plate is that the control rod is accurately positioned at a predetermined position with respect to the mission case, and the change guide plate is accurately positioned with respect to the selector provided on the control rod. This is achieved only by positioning, but if such positioning of the control rod and change guide plate is done manually, the workability is extremely poor and the positioning accuracy is reliable. Therefore, as disclosed in Japanese Utility Model Publication No. 63-32553, for example, the control rod is positioned with respect to the mission case, and at the same time, the change guide plate mission is based on the selector provided on the control rod. Positioning for the case A change guide plate positioning jig has been proposed that is capable of automatically performing.

[0004]

[Problems to be solved by the device]

 By the way, this conventional change guide plate positioning jig positions the change guide plate with respect to the mission case as it is based on the position of the selector provided on the control rod positioned at a predetermined position of the mission case. However, when the position of the selector exactly coincides with the design position, the position of the change guide plate, which is positioned with reference to this position, with respect to the mission case is as designed, and no trouble occurs.

However, in practice, the change arm that serves as the positioning reference of the control rod, the selector, or the like is deformed, and in some cases, a control rod of a different application model (hence, the selector position is naturally different) is also used. It is also conceivable that they will be assembled incorrectly. In such a case, naturally, the position of the change arm is different from the design position, but in the case where the change guide plate is simply positioned with reference to the change arm as described above. Even if the position of the change arm is different from the design position, the position of the change arm is regarded as the normal position and the change guide plate is positioned based on this position.

However, if the change guide plate is positioned and fixed in such an abnormal state, when the change guide plate is incorporated in the transmission as a finished product as one of its constituent members, the actual condition is not achieved. If a change operation is performed, it may be impossible to operate smoothly due to the poor engagement between the guide groove of the change guide plate and the selector, or it may be unusable in extreme cases. However, in the above-mentioned publicly known example, no measures have been taken to prevent the occurrence of such a problem, and therefore, in reality, the operator does not change the position after the change guide plate is positioned and fixed. The current situation is to check the quality of the assembled guide plate.

Therefore, the present invention detects a defect such as deformation or misassembly of the selector or the change arm at the time of positioning the change guide plate, thereby improving the work efficiency by eliminating the setting of the inspection process as a post process. In addition, the above-mentioned problems were detected in the initial stage of the assembly work of the transmission to prevent the occurrence of defective work, and the change guide plate for the transmission is not provided with a positioning jig. Is.

When the lifting frame 15 is moved downward, the fastening heads 17 and 17 of the nut runner devices 16 and 16 temporarily fix the change guide plate 1 to the plate mounting bosses 7 and 7, respectively. The plate mounting bolts 9 and 9 are fitted with each other.

B: Rod Assembly Positioning Device W Further, the rod assembly 5 is positioned on the base plate 20 in the neutral position while the base plate 20 is accurately positioned with respect to the mission case 6. There is provided a rod assembly positioning device W 1 for This rod assembly positioning device W is constructed by attaching a rod 25 having a fitting hole 27 at its lower end to the base plate 20 in a state in which a spring 26 constantly urges the rod 25 toward the fitting hole 27. ing. Then, when the base plate 20 is positioned with respect to the mission case 6 by the positioning pins 22, 22, the operating portion 4a of the change arm 4 is fitted into the fitting hole portion 27 of the rod 25. By doing so, the control rod 3 is accurately positioned at the neutral position.

C: Guide plate positioning device X In the guide plate positioning device X, the change guide plate 1 temporarily fixed on the plate mounting bosses 7, 7 of the mission case 6 is attached to the tip fitting portion 2 a of the selector 2. 2 for positioning, and as shown in FIGS. 2 and 3, the extension arm 31 extending laterally from the base plate 20 can be vertically moved by the elevation cylinder 30. The lift base 34 is supported. The elevating base 34 is guided by the pair of guide rods 33, 33.

Further, on the lower end surface of the elevating base 34, a fixed guide 36 fixed to the elevating base 34 side and a movable guide 37 supported so as to be relatively slidable in the lateral direction with respect to the fixed guide 36. Is attached to the slide mechanism 35. The sliding direction of the movable guide 37 is set to the direction orthogonal to the axial direction of the rod assembly 5, that is, the direction along the rotating surface of the change arm 4.

A plate positioning member 41, which will be described later, is connected to the movable guide 37 via a pivot pin 40 arranged parallel to the sliding direction. As shown in FIGS. 2 to 4, the plate positioning member 41 is provided with a guide hole 42 penetrating in the vertical direction at the axial center thereof, and is orthogonal to the axial direction of the pivot pin 40 on the lower surface side thereof. At both ends in the direction of contact with the projections 11b of the change guide plate 1 are provided with projection fitting portions 43, 43 each having a wedge-shaped fitting recess 44, and both sides of the projection fitting portion 43. Side restricting portions 45, 45 (see FIGS. 4 and 5) are formed on each side.

On the other hand, a selector positioning portion 50, which will be described later, is housed in the guide hole 42. The selector positioning portion 50 is provided with a fitting protrusion 51 having a wedge-shaped fitting recess 52 formed at the lower end thereof, and is continuous with the upper end of the fitting protrusion 51 and slidable in the guide hole 42. It is configured with a guide body portion 53 to be fitted. The selector positioning portion 50 is housed in the guide hole 42 with the fitting protrusion 51 facing downward, and is constantly urged downward by the spring 55. The maximum downward position of the selector positioning section 50 is restricted by the stopper 57 provided on the plate positioning member 41 side. Further, the forming direction of the fitting recess 52 is a direction along the axial direction of the control rod 3. The relative position of the plate positioning member 41 and the selector positioning portion 50 configured as described above is always kept constant in the rotation direction of the change arm 4, and they are slidable by the slide mechanism 35. It will move together with the dynamic displacement. On the other hand, in the radial direction of the selector 2, the relative position between the selector positioning part 50 and the plate positioning member 41 changes as the selector positioning part 50 moves up and down. The sliding displacement of the slide mechanism 35 occurs in correspondence with the change in the position of the tip fitting portion 2a of the selector 2 in the rotating direction, and the selector positioning portion 50 and the plate positioning member 41 are also provided. The relative displacement of the selector in the radial direction (that is, the vertical direction) occurs in correspondence with the radial displacement of the tip fitting portion 2a of the selector 2.

The rotational displacement and radial displacement of the tip fitting portion 2a of the selector 2 are such that the selector 2 and the change arm 4 are not deformed and the rod assembly 5 is applied to this model. If there is no erroneous assembly, it should be within the specified permissible range for the designed position. Therefore, by detecting the rotational displacement and the radial displacement of the tip fitting portion 2a of the selector 2, the presence of deformation of the selector 2 and the change arm 4 and the misassembly of the rod assembly 5 can be detected. The presence or absence can be determined.

From this point of view, in each of the embodiments of the present invention, the vertical displacement of the selector positioning part 50 with respect to the plate positioning member 41 (that is, the vertical positioning of the selector positioning part 50 with respect to the base plate 20) is applied. The first position sensor P for detecting the directional displacement) and the second position sensor P for detecting the sliding displacement of the slide mechanism 35 (that is, the displacement of the selector positioning portion 50 with respect to the base plate 20 in the change arm rotation direction). A position sensor Q is provided.

That is, as shown in FIG. 2, the first position sensor P is attached to the extending arm 31 in the vertical direction on the side portion of the slide mechanism 35 on the side orthogonal to the sliding direction. ing. The detector Pa is brought into contact with the protruding rod 60 protruding from the guide body portion 53 of the selector positioning portion 50 from above. Therefore, the radial position of the tip fitting portion 2a of the change arm 4 is detected by the first position sensor P as the vertical displacement amount of the selector positioning portion 50.

On the other hand, as shown in FIG. 3, the detector Qa is attached to a side portion of the elevating base 34 in parallel with the sliding direction of the slide mechanism 35, and the detector Qa is attached to the above-mentioned detector Qa. It is brought into contact with the end surface 37a of the movable guide 37. Therefore, the rotational displacement of the tip fitting portion 2a of the change arm 4 is detected as the amount of sliding of the movable guide 37 by the second position sensor Q.

Operation of Positioning Jig Next, the operation of positioning and fixing the change guide plate 1 on the side of the mission case 6 using this positioning jig Z and the deformation of the change arm 4 and the like in that case Alternatively, the operation of detecting misassembly will be described.

When positioning and fixing the change guide plate 1, first, the rod assembly 5 is assembled to the change guide plate 1, and the change guide plate 1 is temporarily fixed on the plate mounting bosses 7, 7 of the mission case 6. .. In this state, the elevating frame 15 is moved downward, and the positioning pins 22, 22 of the jig body Y are fitted into the positioning reference holes 8, 8 of the mission case 6 so that the jig body Y and the mission case 6 are separated from each other. Position. In this case, at the same time, the rod 25 of the rod assembly positioning device W is fitted into the operating portion 4a of the change arm 4, so that the change arm 4, that is, the rod assembly 5 is set to the neutral position with respect to the mission case 6. Accurately positioned. At this time, the fastening heads 17, 17 of the nut runner devices 16, 16 are also fitted into the plate mounting bolts 9, 9.

Next, the guide plate positioning device X is moved downward by the elevating cylinder 30, and the respective ridge fitting portions 43, 43 of the plate positioning member 41 are fitted to the ridges 11 b of the change guide plate 1. At the same time, the fitting recess 52 of the selector positioning portion 50 is fitted into the tip fitting portion 2a of the selector 2 (state shown in FIG. 2).

In this case, since the position of the tip fitting portion 2a of the selector 2 is fixed by the rod assembly positioning device W, the fitting recess 52 of the selector positioning portion 50 has the tip fitting portion 2a of the selector 2. If they are displaced in the direction of change arm rotation when they are fitted to each other, the plate positioning member 41 and the selector positioning portion 50 are displaced through the slide mechanism 35 by a dimension corresponding to the displacement amount. The change guide plate 1 is moved by the plate positioning member 41 and positioned at a predetermined position (that is, the change guide plate 1 is positioned with reference to the tip fitting portion 2a of the selector 2).

When the positioning of the change guide plate 1 with the selector 2 as a reference is completed in this manner, the change guide plate 1 is fastened and fixed to the mission case 6 side by the nut runner devices 16, 16. This completes the positioning and fixing work of the change guide plate 1.

Here, when the selector 2 and the change arm 4 are not deformed or the like and the shape as designed is maintained and there is no misassembly, the position of the tip fitting portion 2a of the selector 2 is set. Is within the allowable range with respect to the design position, so there is no problem. As long as the rollers have the above-described positioning structure, the change of the upper side of the selector 2 is based on the tip fitting portion 2a of the selector 2 regardless of whether the upper side is deformed or not. As a result, the change guide plate 1 is positioned and fixed in a state in which the change guide plate 1 is largely displaced from the designed position, which may cause inconvenience such as smooth change operation difficulty in some cases. This is as described above.

Further, in some cases, the fitting recess 52 of the selector positioning part 50 and the tip fitting part 2a of the selector 2 are not properly fitted together, so that the fitting recess 52 and the selector 2 are not fitted together. Even when the tip fitting portion 2a is displaced in the change arm rotation direction, the position of the change guide plate 1 is determined with the selector positioning portion 50 as a reference, so that the same problem as described above occurs. It may occur.

However, in this embodiment, the position of the fitting recess 52 of the selector positioning portion 50 in the selector radial direction and the rotation direction is detected, and the occurrence of the above-described inconvenience is detected from the detected value. At the same time, if it is considered that such an inconvenience has occurred, the positioning and fixing work of the change guide plate 1 is stopped so that the conventional setting of the inspection process after positioning and fixing is unnecessary. At the same time, the production of defective work itself is prevented.

That is, the positions of the selector positioning portion 50 in the selector rotation direction and the radial direction detected by the position sensors P and Q are compared with design values, and when there is a deviation of a predetermined allowable value or more, Is determined to be deformation of the selector 2 or the like, misassembly, or a defect in the positioning operation itself (that is, a defective fitting state between the fitting recess 52 and the tip fitting portion 2a of the selector 2). The change guide plate positioning and fixing work will be stopped.

In this case, when the displacement in the selector radial direction and the rotational direction is detected as in this embodiment, only one of the displacement amounts is equal to or greater than the allowable value. Therefore, even if the other is less than the allowable value, it can be judged with certainty that a defect has occurred, so higher reliability is secured compared to the case of judging only by the displacement of either side, for example. It is something.
