Description

[Detailed Description of the Invention] The present invention is directed to improving the working efficiency of a transmission testing device.

Although a transmission such as an automobile has rotating parts, it does not itself have a drive device, and is connected to a drive device such as an engine only after assembly is completed. It is necessary to perform a rotation test by connecting it to a testing machine that has one. The transmission is attached to an assembly jig, assembled, and transported by a roller conveyor, but assembly jigs generally have low rigidity and have a low natural frequency. If this is done, the assembly jig itself will resonate and vibrate greatly by the time it reaches high speed rotation, which is dangerous. Therefore, it may be considered to increase the rigidity of the assembly jig in order to prevent resonance, but this is not economically viable since a large number of assembly jigs are used. Therefore, conventionally, after assembly, the transmission was removed from the assembly jig, and only the transmission was moved onto a holder installed in the test machine that also served as an oil pan, and the holder was lubricated with oil stored in the holder. I was doing a rotation test. Therefore, it is necessary to transfer the mission from the conveyance line to the testing machine, and also to transfer it to a conveying pallet after the test, resulting in a decrease in work efficiency.

The present invention has been developed in view of the above points, and uses an assembly jig for the transmission to transport the transmission to the testing machine, and also uses the assembly jig to continue transporting the transmission after the test. The purpose is to improve work efficiency by doing so. The configuration of the transmission testing device of the present invention for achieving such an object is such that a testing device and an oil pan support are provided facing each other with a conveyor on which a transmission mounted on an assembly jig is conveyed, and the oil pan The support body is moved toward and away from the test machine so that its tip can be inserted into the lower part of the transmission on the conveyor attached to the test machine, and a support body is formed on the top surface of the tip of the oil pan support body. The oil pan is characterized in that an oil pan is installed in the oil pan storage portion to support the transmission via a push-up plate that is driven up and down by a cylinder.

An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is an external perspective view of an embodiment of the present invention, and FIG. 2 is a longitudinal cross-sectional view of an oil pan housing section.

The mission 1 is assembled by being suspended from an assembly jig 3 by a hanging jig 2, and is conveyed by a roller conveyor 4 using the assembly jig 3. That is, the assembly jig 3 has an L-shaped cross section with a bottom plate 3a placed on the roller conveyor 4 and a standing plate 3b rising from the bottom plate 3a, and the hanging jig 2 is mounted on the top of the standing plate 3b. When mounted, the fitting 2b is opened and closed by rotating the handle 2a, thereby suspending the mission 1. A testing machine 5 is disposed on the side of the fixed position of the roller conveyor 4, and the testing machine 5 is movable in a direction perpendicular to the conveying direction of the roller conveyor 4. In the figure, the driving device and the like at the rear of the testing machine 5 are omitted, and only the face plate 6 and clamper 7 at the front are shown.

On the other hand, an oil pan support 8 is provided in front of the testing machine 5 so as to face the roller conveyor 4 therebetween. Two slide guides 8a are formed on each side of the lower surface of the oil pan support 8, and two mutually parallel guide bars are formed toward the testing machine 5 in a direction perpendicular to the conveying direction of the roller conveyor 4. 9
is fixed to the stand via its guide bearing 9b, and the slide guide 8a is slidably inserted into the guide bar 9, so that the oil pan support 8 can be moved toward and away from the testing machine 5. The tip part can be inserted into and removed from the roller conveyor 4 at the front of the testing machine 5. Further, a cylinder 10 is fixedly installed between the two guide bars 9, and its piston rod 10a is attached to the lower surface of the oil pan support 8.
0 to drive the oil pan support 8 back and forth toward the testing machine 5. The tip of the oil pan support 8 is dimensioned so that it can be inserted into the space between the bottom plate 3a of the assembly jig 3 placed on the roller conveyor 4 and the upper transmission 1 attached to the assembly jig 3, An oil pan storage portion 8b, which is a rectangular space, is formed on the upper surface thereof. A push-up plate 11 is inserted into the oil pan storage portion 8b so as to be able to move up and down, and a mini chia cylinder 12 provided at the bottom of the oil pan storage portion 8b is connected to the lower surface of the push-up board 11. Make it drive up and down. An oil pan 13 is installed on the upper surface of the push-up plate 11.
is placed, and the oil pan 13 protrudes to the upper surface of the oil pan support 8 by the vertical movement of the push-up plate 11.
Alternatively, it is stored in the oil pan storage section 8b.
Moreover, 8c, 11a, and 13a are an oil pan support oil discharge hole, a push-up plate oil discharge hole, and an oil pan oil discharge hole, respectively, and 13b is an oil pan oil supply hole.

In such a configuration, the assembled transmission 1 is transported by the roller conveyor 4 while being attached to the assembly jig 3, and when it comes in front of the testing machine 5, the oil pan support 8 is first moved by the cylinder 10. The test machine 5 is moved forward toward the test machine 5, and the oil pan 13 in the oil pan storage section 8b is positioned below the transmission 1. The oil pan 13 is raised via the push-up plate 11 by the mini chia cylinder 12, and the oil Support mission 1 with bread 13. Next, the testing machine 5 is moved forward to connect its driving device and the transmission 1, and the transmission 1 is brought into contact with the face plate 6 and fixed with the clamper 7, after which the hanging jig 2 is loosened and the assembly jig is assembled. Cut the connection between 3 and Mission 1. Then, test machine 5 performs mission 1.
The specified test is carried out, and after the test is completed, the hanging jig 2 is
is tightened to move the testing machine 5 and oil pan support 8 backward, and then the assembly jig 3 is used to transport the mission 1.

As described above in detail with reference to one embodiment, according to the testing device of the present invention, the assembly jig of the transmission is used to transport the transmission to the testing machine position, and the assembly jig is also used after the test. This allows the specimen to be transported by using the test equipment, eliminating the need for loading and unloading the transmission onto the testing machine, thereby improving testing efficiency. Further, since there is no need to make any changes to the conventional assembly jigs, many existing jigs can be used as they are, which is economically advantageous.
