Various preparation of this simplified jig can easily correspond also to multiplicity in kinds of the transmission.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a relative positioning device for a vehicle engine and a transmission when the vehicle engine and transmission are assembled.

In order to assemble a vehicle engine and a transmission controller, it is necessary to accurately align the relative positions of the two. Conventionally, this alignment has generally been accomplished by using an electric hoist as shown in Figure 3. was. That is, the transmission T to be assembled to the engine E is suspended by an electric hoist H, and the engine is placed on a pedestal S on a conveyor C by operating the electric hoist H to move the transmission T back and forth and left and right. Relative positioning with E was being performed. For this reason, traditional methods often rely on the intuition and skill of the worker.
There was a problem that alignment accuracy and workability were poor.

The present invention solves the above problem by having the structure described in the claims, and provides a novel relative positioning device that does not rely on a positioning method using an electric hoist.

The present invention will be described in detail below based on the embodiments shown in FIGS. 1 and 2.

The basic configuration of the present invention is as follows: a simple jig 1 for positioning the transmission T; a transmission side support stand 2 used as a means for supporting the simple jig 1 and transporting the transmission T; and a stand 2 for supporting the engine E. In addition, the engine side support used as a means for conveying the engine is composed of a stand 3.

The receiver has a cover plate 4 disposed below the stands 2 and 3, and is arranged to be able to move up and down by an actuator 5 and a guide post 6. Engine side support is stand 3
is positioned by fitting a positioning hole 7 formed on the bottom surface with a positioning pin 8 of the lifter paste 4. In addition, the transmission side support mounted on the lifter pace 4 is configured such that the stand 2 can move forward and backward along the sliding guide 20 by an actuator 21, and the supports are formed on the opposing surfaces of the stands 2 and 3, respectively. By fitting the positioning pin 22 and the positioning hole 23 together, they are positioned. The engine side support is established on the stand 3, and the engine E is placed on the attachment 9 and is supported in an accurately positioned state.

The transmission T is suspended and supported on the lower surface of a simple jig 1 by means to be described later, and the simple jig 1 has a transmission side support set on a stand 2, and a support placed on an attachment 10. ing. This simple jig 1
In the case of the illustrated example, it is a square-shaped plate body, and positioning holes 12 are bored at the tips of both wings to fit with positioning pins 11 of the receiver attachment 10.

Further, a positioning pin 15 that is fitted into the machined hole 14 of the machined part 13 of the +-transmission T is provided at the lower end of the jig 1, and a positioning pin 15 is provided at the lower end of the rear end to fit into the machined hole 14 of the machined part 13 of the +-transmission T. A spline fitting portion 17 is provided which fits into the spline processing portion 16 of the shaft. The positioning pin 15 is attached to the sliding case 1
The spline fitting portion 17 is rotatably slidable in the direction of arrow (B) by means of a sliding rotation bearing 19, and these positioning pins 15 and The transmission T is detachably suspended from the simple jig 1 by a spline fitting part 17.

The device of the present invention having the above configuration is used in the following manner.

The engine E is mounted on an attachment 9, and the engine side support is placed on the attachment 9, and the support is fitted with the positioning pin 8 of the lifter pace 4 and the positioning hole 7 on the lower surface of the support. It is placed on the lifter base 4 and its position is accurately set.

On the other hand, the transmission T is constructed by fitting the positioning pin 15 provided at the tip of the simple jig 1 into the machined hole 14 of the machined part 13 of the transmission T, and further inserting the spline fitting part 17 provided at the rear end of the simple jig 1. By fitting into the splined portion 16 of the transmission, the simple jig 1 is suspended at a predetermined position on the lower surface of the jig 1.

The simple jig 1 on which this transmission T is suspended is connected to the positioning holes 12 on both wings and the positioning pins 1 on the attachment 10 on the transmission base 2.
1, the receiver of the transmission base 2 is placed on the attachment 10.

After the engine E and transmission T are placed facing each other in the predetermined positions on the bases 2 and 3, the receiver is
Transmission Aiai pushes platform 2 forward by actuator 21. As a result, the engine support moves along the sliding guide 20 and above the turbine base 4 toward the support 3, and finally the positioning pin 22 at the tip of the support 2 moves toward the support. The engine receiver is inserted into the positioning hole 23 on the third side, and the relative positioning of the engine support 3 and the transmission support 2 is completed. At this time, the relative position of engine E and transmission T is
Since the receiver is accurately positioned in advance by the tables 2 and 3 and the simple jig 1, the receiver can be positioned by fitting the positioning pins 22 and the positioning holes 23 of the tables 2 and 3 together.
Engine E and transmission/T are aligned so that their centers exactly match.

The aligned engine E and transmission T are assembled into one body by performing necessary assembly operations.

After the assembly is completed, the positioning pin 15 of the simple jig 1 and the spline fitting part 17 are slid to the right in the figure, and the machined hole 14 of the transmission T is
The series of operations is completed by removing the fitting between the transmission part 1 and the splined part 16, retracting the transmission stand 2, and removing the simple jig 1 from the support 10.

The present invention has two functions as described in detail above, in which the simple jig and the holder are used to position the table, the holder is used to position the pedestals to each other, and the holder is used to position the pedestal and the lid base. Since this is done by fitting a pin and a positioning hole, it has a simple structure and is effective in that accurate positioning can be reliably realized. In addition, by preparing various simple jigs depending on the form of the transmission,
It can easily accommodate a wide variety of transmission types, and has the remarkable effect that assembly lines can be changed without changing the structure of the entire conveyance system.
