BACKGROUND OF THE INVENTION
The present invention relates to an improvement of an assembly carriage used when an outboard motor is assembled.
[0002]
[Prior art]
The outboard motor is a propeller type propulsion mechanism that is attached to the stern with a stern bracket. For such outboard motors, it is necessary to perform a performance test in a water tank after assembly. For this reason, it is convenient to set the outboard motor on the assembly cart, assemble it, and transport the assembled outboard motor to the inspection line while it is set on the assembly cart, and the equipment cost can be reduced. As an outboard motor production facility for performing outboard motor assembly and performance inspection in this way, for example, Japanese Patent Application Laid-Open No. 11-34884 “Outboard motor assembly device” (hereinafter referred to as “conventional technology”). )It has been known.
[0003]
In the prior art, as shown in FIG. 1 of the publication, the engine is assembled by the engine assembly section 2 (the reference is quoted from the publication). The outer motor is assembled by the parts assembly unit 3 and the performance of the assembled outboard motor is inspected by the performance confirmation unit 4.
The parts assembly unit 3 is provided with an assembly conveyance path 6 so as to connect a plurality of stations, so that the assembly cart 8 is pulled by the unmanned car 7 along the assembly conveyance path 6 and stopped at each station. The outboard motor can be assembled on the assembly cart 8.
[0004]
As shown in FIGS. 2 and 3 of the above-mentioned prior art, the assembly cart 8 is a cart in which a post 20 is erected from a frame base 18 having wheels and an inclined plate 24 is provided on the upper end of the post 20. is there. The outboard motor S can be set on the inclined plate 24.
[0005]
[Problems to be solved by the invention]
By the way, there are a wide variety of outboard motors, and the size varies depending on the type. For example, there is a small outboard motor equipped with a small engine with an output of about 1 kW to a large outboard motor equipped with a large engine with an output of about 100 kW.
However, according to the conventional technology, it is impossible to assemble outboard motors having greatly different sizes from a small size to a large size with one kind of assembly cart 8. On the other hand, it is conceivable to prepare a plurality of types of assembly carts 8 according to the size of the outboard motor, but this is not a good idea because the equipment cost increases significantly.
[0006]
Accordingly, an object of the present invention is to provide a technology that can efficiently assemble a plurality of types of outboard motors having significantly different sizes with a single type of outboard motor assembly cart.
[0007]
[Means for Solving the Problems]
  In order to achieve the above object, claim 1 provides an outboard motor assembly cart in which the outboard motor is set and assembled, and the assembled outboard motor is transported to the next process as it is. On the bodyAnd a column provided in the center of the running directionA first set for setting the large outboard motor in the upper center is provided.The strutThe second set part for setting the small outboard motor on the left and right sides of the first set partThe second set part is attached so as to be movable in the horizontal direction.It is provided so that it can be folded.
  A second aspect of the present invention is characterized in that, in the first aspect, the first and second set portions are arranged substantially in a straight line when the second set portion is opened in the horizontal direction.
[0008]
  When assembling a large outboard motor,Mounted on the main body of the carriage and horizontally in the center of the support column provided in the center of the running direction.Fold the left and right second set parts and set one large outboard motor in the first set part. When assembling the small outboard motor,Move it horizontally,Open and set two small outboard motors in these second set parts. By doing so, a large outboard motor or a small outboard motor can be assembled by one outboard motor assembly cart. Therefore, outboard motors having significantly different sizes can be efficiently assembled with one type of outboard motor assembly cart.
[0009]
Furthermore, when assembling a large outboard motor, the left and right second set parts can be folded so as not to interfere with the assembling work. Therefore, the assembly work of the large outboard motor can be easily performed with an easy posture even though the outboard motors having greatly different sizes are assembled by one type of outboard motor assembly cart. For this reason, an operator's burden can be reduced more.
[0010]
Furthermore, in general, the assembly time for a small outboard motor is significantly shorter than the assembly time for a large outboard motor. Therefore, when two small outboard motors are set on the left and right second set parts and assembled at the same time, (1) the time required to assemble one large outboard motor, (2) two small ships An external unit can be assembled. For this reason, the assembly man-hour of (1) and the assembly man-hour of (2) can be made substantially uniform. As a result, variations in assembly man-hours for outboard motors having different sizes can be eliminated, and assembly efficiency can be further increased.

[0040]
Next, the operation of the connecting pin mechanism 240 having the above configuration will be described with reference to FIG.
(A) shows that the connecting pin mechanism 240 is in a locked state. Since the lock plate 244 is fitted in the recess 225, the link 223 cannot move.
In this state, when the knob 243 is picked and pulled up against the elastic force of the return spring 245, the slide pin 242 moves upward. This result is shown in (b). Since the lock plate 244 is removed from the recess 225, the connecting pin mechanism 240 is unlocked.
[0041]
Next, the operation of the first and second set portions 204, 205, 205 and the connecting pin mechanism 240 configured as described above will be described with reference to FIGS.
FIG. 6 shows a state in which two second set units 205 and 205 are opened with respect to the first set unit 204. When the knob 243 on the left side of the figure is pulled up in this state, the lock plate 244 is removed from the one recess 225. With the knob 243 being pulled up, the second set portion 205 on the left side of the figure is closed in the direction of the arrow. As a result, the long hole 224 of the link 223 moves while being guided by the slide pin 242.
[0042]
When the long hole 224 moves to the end, the other recess 226 comes to the position of the lock plate 244. When the hand is released from the knob 243 at this time, the slide pin is lowered by the elastic force of the return spring 245. As a result, the lock plate 244 is fitted into the other concave portion 226 to be locked. In this way, the second set part 205 on the left side of the figure can be folded.
The same operation can be performed to fold the second set unit 205 on the right side of the figure. This state is shown in FIG.
[0043]
FIG. 9 is an operation diagram of the first and second set portions and the connecting pin mechanism according to the present invention, and shows a state where the two second set portions 205 and 205 are folded with respect to the first set portion 204. Since the connecting pin mechanisms 240 and 240 are in the locked state, the two second set portions 205 and 205 do not open. In order to open the second set portions 205 and 205, the second set portions 205 and 205 may be returned to their original positions while pulling up the knobs 243 and 243 of the connection pin mechanisms 240 and 240 again.
[0044]
Next, a method of using the outboard motor assembly cart 200 configured as described above will be described with reference to FIGS.

(B) shows the front of the outboard motor assembly cart 200 at that time.
[0046]
Thus, one large outboard motor B1 shown in FIG. 10 can be assembled by one outboard motor assembly cart 200, or two small outboard motors B2 and B2 shown in FIG. 11 can be assembled. Therefore, the outboard motors B1, B2, and B2 having significantly different sizes can be efficiently assembled by using one type of outboard motor assembly cart 200.
[0047]
Furthermore, when assembling the large outboard motor B1, the left and right second set portions 205, 205 can be folded so as not to interfere with the assembling work. Therefore, despite the fact that the outboard motors B1, B2, and B2 having significantly different sizes are assembled with one type of outboard motor assembly cart 200, the assembly work of the large outboard motor B1 can be easily performed in an easy posture. Can be done. For this reason, an operator's burden can be reduced more.
[0048]
Furthermore, in general, the assembly time of the small outboard motor B2 can be significantly reduced as compared with the assembly time of the large outboard motor B1.
Therefore, when two small outboard motors B2 and B2 are set on the left and right second set parts 205 and 205 and assembled at the same time, (1) the time required for assembling one large outboard motor B1 is: (2) Two small outboard motors B2 and B2 can be assembled. For this reason, the assembly man-hour of (1) and the assembly man-hour of (2) can be made substantially uniform. Since variations in assembly man-hours of outboard motors B1, B2, and B2 having different sizes can be eliminated, assembly efficiency can be further increased.
[0049]
Moreover, in one kind of outboard motor assembly cart 200, (1) one large outboard motor B1 is set and assembled in the first set unit 204, or (2) one small outboard motor B2 is left or right. (3) Two small outboard motors B2 and B2 can be set in the left and right second set parts 205 and 205 and assembled at the same time. Therefore, the outboard motors B1 and B2 having significantly different sizes can be assembled more efficiently by using one type of outboard motor assembly cart 200.
[0050]

  By doing so, a large outboard motor or a small outboard motor can be assembled by one outboard motor assembly cart. Therefore, outboard motors having significantly different sizes can be efficiently assembled with one type of outboard motor assembly cart.
[0056]
  Furthermore, when assembling a large outboard motor,The upper part of the column is provided so that it can move in the horizontal direction.Make sure that the left and right second set parts do not interfere with assembly work.Move it horizontallyBecause it can be folded, it is easy to assemble large outboard motors in an easy position despite the fact that outboard motors of significantly different sizes are assembled with one type of outboard motor. be able to. For this reason, an operator's burden can be reduced more.
[0057]
Furthermore, in general, the assembly time for a small outboard motor is significantly shorter than the assembly time for a large outboard motor. Therefore, when two small outboard motors are set on the left and right second set parts and assembled at the same time, (1) the time required to assemble one large outboard motor, (2) two small ships An external unit can be assembled. For this reason, the assembly man-hour of (1) and the assembly man-hour of (2) can be made substantially uniform. As a result, variations in assembly man-hours for outboard motors having different sizes can be eliminated, and assembly efficiency can be further increased.
