[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a test stand which is installed in a production line of an automobile engine and tests an engine.

[0002]

2. Description of the Related Art An automobile engine is mounted on a pallet because an oil pan travels downward and is unstable, and is transported to a test stand by a transport device such as a floor conveyor or a self-propelled automatic transport vehicle. Transferred on the shuttle. The shuttle is a kind of buffer provided integrally with the test stand. Two engines can be mounted in parallel on a table that moves left and right.

FIG. 3 is a plan view showing a conventional test stand. When the engine 4 is transferred from the automatic carrier 1 onto the table 3 of the shuttle 2, the table 3 moves to the left on the shuttle 2. Then, the engine 5 which has already been tested is transferred to the automatic transport vehicle 1, and the automatic transport vehicle 1 runs away to the next station. Reference numeral 6 denotes an engine under test. When the test is completed, the engine 6 is placed after the unloaded engine 5 on the table 3, the table 3 is moved rightward, and the engine 4 is loaded into the test stand 7. After the engine 4 on the table 3, a new engine carried by the automatic transport vehicle 1 is placed, the table 3 moves to the left, and the engine 6 which has completed the test is the automatic engine carrying the new engine. It is transferred to a carrier and transported to the next station. The engine 4 carried into the test stand 7 is connected to a power absorber 9 by a connecting shaft 8 and is started after a fuel supply pipe, a cooling water pipe, an exhaust pipe, a battery power supply, and the like are connected. After the adjustment of each part including the idle adjustment, an operation test is performed in accordance with a predetermined operation pattern, and after the test result is determined, the engine 6 on the table 3 is moved out. Reference numeral 10 denotes an operation stand provided with instruments and switches.

[0004]

[Problems to be solved by the invention] Various adjustment operations cannot be performed only from one side of the engine, but must be performed from both left and right sides of the engine. In particular, noise (abnormal sound) and vibration during a driving test can be felt by the inspector. In addition, since the water and oil leaks rely on visual inspection, the inspector indicated by A in FIG. 3 turns around the power absorber 9 and moves between the position B indicated by the dotted line. It has to come, increasing the fatigue of inspectors and reducing work efficiency.

An object of the present invention is to provide a test stand for an engine that can improve work efficiency and reduce fatigue of inspectors.

[0006]

Means for achieving the above object are to separate the shuttle from the test stand so that the inspector can pass through and perform the inspection and adjustment of the engine. It is an object of the present invention to provide a gap, and to provide a telescopic power roller for carrying the engine into or out of the test stand beyond the gap.

[0007]

The inspector can perform inspection and adjustment from both the left and right sides of the engine through the gap between the shuttle and the test stand without bypassing the rear of the power absorber, and can perform inspection and adjustment from the front. Work is also easier.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to an embodiment shown in the drawings.

1 and 2 show an embodiment of the present invention. FIG. 1 is a side view, and FIG. 2 is a plan view for comparison with FIG. In FIG. 3, the same portions are denoted by the same reference numerals, and description thereof will be omitted.

In FIG. 1, reference numeral 11 denotes a test stand from which the shuttle 2 has been separated. An inspector can pass between the test stand 11 and the shuttle 2 and can inspect and adjust the engine 4 to be tested. A gap 12 is provided. Reference numeral 13 denotes a test stand 1 via a mounting plate 14.
A hydraulic cylinder fixed to 1 is connected to a telescopic power roller 17 that slides on a slide rail 16 fixed on the test stand 11 by a connecting rod 15.

When the test of the engine 6 is completed, the telescopic power roller 17 (hereinafter referred to as the telescopic power roller) is pushed out by the hydraulic cylinder 13 and extends over the gap 12 as shown by a two-dot chain line. The engine 6 is returned to the table 3 of the shuttle 2, and the engine 4 to be tested next is carried into the test stand 11. When the engine 4 is carried in, the telescopic power roller is pulled back into the test stand 11 by the hydraulic cylinder 13 to maintain a gap between the shuttle 2 and the test stand 11. The engine 4 is stopped at a predetermined position by a stopper, connected to the connection shaft 8 with the power absorber 9, and the test is started.

FIG. 2 is a plan view similar to FIG. 3 when the engine 6 is being tested, and the inspector A passes through the gap 12 without bypassing the power absorber 9 and on the opposite side of the engine 6. Not only can B be reached, but also the inspection and adjustment of the engine 6 can be performed from the front side C, so that the reliability of the inspection and the work efficiency of the adjustment are improved and the fatigue of the inspector is reduced.

The hydraulic cylinder 13 may be a pneumatic cylinder or an electric cylinder.

Although not shown, a stand roller for guiding and supporting the engine to be tested at a predetermined position on the test stand 11 with higher accuracy is provided, and the width of the stand roller is reduced to slightly increase the inside of the stand roller. After the telescoping power roller 17 is moved to a lower position, the telescoping power roller 17 is extended from the hydraulic cylinder 13 and then raised to a position slightly higher than the stand roller to return the engine 6 having completed the test to the table 3. Then, when the engine 4 to be tested is loaded from the table 3 above the stand roller, the telescopic power roller is lowered to its original position and pulled back by the hydraulic cylinder. The operation can be performed without a load on the vehicle without a load, and the wear of the slide rail can be prevented.

[0015]

[Effect of the Invention] The shuttle-separated engine test stand according to the present invention separates the shuttle and the test stand so that the inspector can pass through and a gap necessary for performing inspection and adjustment of the engine is provided. Therefore, the inspector not only can perform the inspection and adjustment of the engine from both the left and right sides of the engine without detouring behind the power absorber, but also can perform the inspection and adjustment from the front, thus improving the reliability of the inspection. Improve work efficiency and reduce inspector fatigue.
Further, the provision of the telescopic power roller has a practical effect that the loading and unloading of the engine from the shuttle to the test stand can be performed easily as in the conventional case.
