Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a jig for engine support.

[0002]

[Prior Art]

 As is well known, when the engine A as shown in FIG. 4 is integrated with the side frame in the engine room, the operation of fastening the engine mount B with bolts is performed. By the way, in the above-mentioned engine mount B, the engine mount B1 and the transmission mount B2 located at each end of the engine in the front-rear direction are located substantially above the cylinder block, and the mount B3 as a roll stopper is located substantially below. Existing.

When the mount is fastened, for example, the lower part of the vehicle body suspended by the hanger is made visible to the operator, and the above-mentioned roll stopper mount B3 is fastened, and then the hanger is fastened. A work procedure may be set for lowering and mounting the remaining mounts B1 and B2 from above the engine room.

Therefore, it is necessary to prevent the engine A from falling off by temporarily fixing the mount on the upper side while fastening the mount at the lower position of the engine. Therefore, as shown in FIG. 5, an engine support jig C composed of a pair of rod members C2 and C3 whose end portions on the same side in the axial direction are fixed to a base C1 is prepared. In the engine support jig C, one rod member C1 is formed in the hole D1 formed in the side frame D, and the other rod member C2 is formed in, for example, the engine-side center pulley A1. The engine A is held by the side frame D by fitting into the formed holes from the same side.

[0005]

By the way, in the engine support jig described above, when the weight from the engine is applied, it corresponds to a play due to a dimensional error generated between the hole and the rod member. There is a tendency for the engine side to drop by the amount that is done. In particular, if you try to fasten the mount in the upper position with the engine side lowered, the fastening position, that is, the center position for inserting the bolt will shift, and moreover the above-mentioned Since the pitch between the rod members is fixed, it is impossible to adjust the position, and there is a problem that it is difficult to obtain the consistency of the center position when fastening with bolts.

In addition, when the above-described jig for engine support is mounted, for example, when the mount is elastically deformed by the weight of the engine and the engine side is lowered, the pitch between the rod members is reduced. Since it is fixed, there is a risk that it will not be possible to insert it into the engine side, and there was a problem that it took too much time to install it.

Therefore, an object of the present invention is to provide a fastening position of a mount between an engine and a frame in an engine room, in view of the above-mentioned problems in the conventional jig for engine support. It is to obtain an engine support jig having a structure that can surely obtain consistency and can be easily attached to an engine.

[0008]

[Means for Solving the Problems]

 In order to achieve this object, the present invention is an engine support jig used for preventing the engine from falling off during the assembly work for fastening the engine mount, and is a base corresponding to the same side in the axial direction. It has a pair of rod members whose ends are supported by the same base material, one of the rod members is fixed to the same member, and the other rod member is rotatable to the same member. A ratchet wheel and a rotary drive member of the ratchet wheel are fixed together at the base end portion of the other rod member in the axial direction, which is supported on the opposite side of the base end portion. An eccentric head set with the center of rotation eccentric is provided at the tip end in the axial direction, and a ratchet that is normally given a habit of engaging with the ratchet wheel swings on the base material. The position of the eccentric head in the other rod member is changed by rotating the rotation drive member so that the distance between the rod member and the other rod member can be changed. It has a feature.

[0009]

[Action]

 According to the present invention, the distance between one rod member and the other rod member can be changed by rotating the eccentric head located at the axial tip of the other rod member.

[0010]

【Example】

 Hereinafter, the details of the embodiment of the present invention will be described with reference to FIGS.

FIG. 1 is a perspective view showing an overall configuration according to an embodiment of the present invention. In FIG. 1, an engine support jig 1 according to this embodiment includes a pair of rod members 2 and 3. The rod members 2 and 3 are supported by the same base material 4 at one end in the axial direction. That is, as shown in FIG. 2, one of the rod members 2 is inserted into a hole penetrating the base material 4 and fixed by welding, and the other rod member 3 has a structure described later. It is rotatably supported.

The other rod member 3 described above has one end in the axial direction inserted through the base material 4, and the ratchet wheel 5 and the ratchet wheel 5 are inserted into the end portion of the rod member 3 via a key (not shown). The bolts 6 forming the rotary drive member of the tool 5 are fixed together. Therefore, the ratchet wheel 5 is interlocked by the rotating operation of the bolt 6, and the amount of rotation is fixed to the pin 5A fixed to the end surface of the ratchet wheel 5 facing the base material 4 side. (See FIG. 2) is set by engaging the arc-shaped restriction groove 4A (see FIG. 2) formed on the base material 4 side. In the initial state, the restriction groove is set. The pin 5A is located at the center of 4A.

Then, as shown in FIG. 2, an eccentric head portion 3A having an eccentric center of rotation with respect to the rod portion is provided at a tip end portion corresponding to the other axial end of the other rod member 3.

On the other hand, a ratchet 7 is arranged at a position corresponding to the ratchet wheel 5 on the base material 4 described above. That is, the ratchet 7 is swingably supported via a support shaft 8 provided on the base material 4, and is provided with a spring 9 arranged between one of the swing ends and the base material 4. By force, the pawl located on the other side of the swinging end is engaged with the ratchet wheel 5. In this ratchet 7, the pressing portion 7A provided on one of the swing ends is pushed against the bias of the spring 9 so that the pawl located on the other of the swing ends can be removed from the ratchet wheel 5. You can do it.

Since the present embodiment has the above-described structure, in FIG. 3, when temporarily fixing the engine when fastening the lower mount of the engine, an engine support jig is used. The rod members 2 and 3 of No. 1 are fitted into the holes formed in the frame 10 in the engine room and the holes in the center pulley on the engine side, respectively. In this case, for example, the position of the eccentric head 3A on the other rod member 3 is set to the position indicated by reference numeral L1 in FIG. 3 by rotating the bolt 6, in other words, the position of the eccentric head 3A on the other rod member 2 is set. If the pitch between the rods is increased and it does not match the center pulley hole on the engine side in this state, the bolt 6 is rotated to move one rod to the other rod, as indicated by the symbol L1 in FIG. The pitch with the member 2 can be easily aligned with the other rod member 3 and the hole of the center pulley, and this state can be maintained by the engagement of the ratchet 7. Therefore, the mounting position can be easily adjusted when mounting the engine support member.

The above-described adjustment of the pitch between the rod members by the rotation of the eccentric head is also performed when adjusting the fastening position of the lower mount, which allows the center of the fastening position to be easily positioned. ..

Further, when the fastening of the mount on the lower side of the engine is completed, the fastening position of the upper mount is automatically determined. Therefore, the jig 1 for engine support is removed from each hole, The ratchet wheel 5 is released from the locked state by the ratchet 7 and the ratchet wheel is restored to the initial state.

[0018]

[Effect of the device]

 As described above, according to the present invention, the arrangement pitch of the pair of rod members fitted into the holes formed on the frame in the engine room and the engine side can be varied. By adjusting the pitch, it is possible to easily obtain the consistency when determining the center of the mounting position of the mount, and also to perform the positioning easily and accurately when mounting the engine support jig.
