Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a coupling device for coupling a transmission to an engine.

[0002]

[Prior art]

 When connecting an automobile engine and transmission, as shown in Fig. 5, the transmission 1 is hung by a crane or a hoist, and the operator aligns the engine 3 mounted on the upright stand 2 by hand, The shafts are fitted together. In this case, the engine 3 is carried by the conveyor 4, and the two workers who are placed across the conveyor 4 swing the transmission 1 back and forth (X direction in the figure) and rotate the shaft to rotate the engine 3 and the engine 3. Fit the transmission 1.

[0003]

[Problems to be solved by the device]

 In the conventional connection between the transmission 1 and the engine 3, since the transmission 1 having a complicated shape is hoisted, it is unbalanced and dangerous, and a great amount of labor and time are required for the shaft fitting work. There was a risk of damaging the fitting part of the shaft.

Further, the transmission 1 and the engine 3 are placed on a lifter for alignment, and a multi-axis control robot is equipped with a CCD (charge coupled device) camera to check the fitting position, and the transmission is fully automatic. It is done to connect 1 and the engine 3. However, the fitting tolerance of the shafts of the transmission 1 and the engine 3 is about 25 to 125 μm, and it is necessary to configure the lifter and the drive mechanism with extremely high accuracy. This makes the device very expensive and complicated to control.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a transmission coupling device that can easily couple a transmission and an engine with a simple mechanism.

[0006]

[Means for Solving the Problems]

 The structure of the present invention for solving the above-mentioned problems is a dolly positioned with respect to an engine, a frame on which the dolly is supported so that the transmission can be mounted thereon, and a transmission mounted on the frame so as to reciprocately support the transmission. A conveyor, an elevating cylinder that elevates and lowers the frame with respect to the carriage, and a support that is provided adjacent to the elevating cylinder along the moving direction of the transmission and that swings and supports the frame with respect to the carriage. It is characterized by comprising rocking cylinders which are provided in the front-rear direction and in the left-right direction of the transmission and for rocking the frame in the front-rear direction and the left-right direction with respect to the carriage.

[0007]

[Action]

 Place the transmission on the frame and move the carriage to position the transmission with respect to the engine. The frame is rocked back and forth and left and right with respect to the bogie to align the shafts, and the conveyor is moved to move the transmission to couple the transmission with the engine.

【Example】

 1 is a front view of a transmission coupling device according to an embodiment of the present invention in a partially broken state, FIG. 2 is a view taken along the line II-II in FIG. 1, and FIG. 3 is a line III-III in FIG. The arrow is shown.

A truck 13 is movably supported by a rail 11 laid on the floor via wheels 12, and the truck 13 is moved along the rail 11 to be positioned with respect to an engine (not shown). A linear rail 15 is erected in front of and behind the carriage 13 via a bracket 14, and a base plate 17 is movably supported on the linear rail 15 via a bearing 16.

A lift cylinder 18 is fixed to the carriage 13, and a piston rod 19 of the lift cylinder 18 is fixed to the base plate 17. By driving the lifting cylinder 18, the base plate 17 moves up and down with respect to the carriage 13. A frame 21 is supported on the base plate 17 via a floating joint 20 as a support tool, and the frame 21 is swingable with respect to the base plate 17.

Two sprocket wheels 22 are provided at each of the front and rear ends (left and right ends in FIGS. 1 and 3) of the frame 21, and a conveyor chain 23 is wound around the sprocket wheels 22 facing each other. The sprocket wheels 22 on the rear end side (left side in FIG. 3) are attached to a drive shaft 24, and a drive sprocket wheel 25 is fixed to the end portion of the drive shaft 24. The frame 21 is provided with an air motor 26, and a drive chain 28 is wound around an output sprocket 27 of the air motor 26 and a drive sprocket 25.

That is, by driving the air motor 26, the sprocket 22 is driven and rotated through the output sprocket 27, the drive chain 28, and the drive sprocket 25, and the transmission 29 mounted on the frame 21 is reciprocated by the chain 23 ( (Figure 1 left and right direction). The lifting cylinder 18 and the floating joint 20 are adjacent to each other along the moving direction of the transmission 29, and the frame 21 is swung back and forth and left and right in the moving direction of the transmission 29.

A swing cylinder 30 is provided on the base plate 17 at four corners of the frame 21 (forward and backward and left and right in the moving direction of the transmission 29), and a pin 32 is attached to a piston rod 31 of the swing cylinder 30. A pedestal 33 that slidably supports the pins 32 is fixed to the lower surfaces of the four corners of the frame 21, and the four swing cylinders 30 can be independently driven.

In FIG. 2, reference numeral 34 is a guide provided on the side portion of the frame 21, and 35 is a safety bumper provided in front of and behind the carriage 13. Further, the carriage 13 is self-propelled by the driving of the drive motor 36 with a reduction gear, and when the safety bumper 35 comes into contact with an obstacle, the drive motor 36 is stopped and the carriage 13 stops traveling.

The rail 11 is laid adjacent to the engine-transporting conveyor 37 shown in FIG. 4, and traveling of the carriage 13, lifting and lowering and swinging of the frame 21, and driving of the conveyor chain 23 are provided on an operation panel or the like. It is performed by operating the switch.

In the above embodiment, the lifting cylinder 18 and the floating joint 20 are provided separately, but two lifting cylinders 18 and floating joints 20 may be provided.

The operation of the transmission coupling device described above will be described with reference to FIG. FIG. 4 shows the coupling state by the transmission coupling device.

The transmission 29 is supported on a pallet 38 and placed on the frame 21. The engine 39 is supported on an upright stand 40 and is conveyed by a conveyor 37.

The carriage 13 is caused to travel along the rails 11 and the transmission 29 is positioned with respect to the engine 39 conveyed to a predetermined position. The frame 21 is moved up and down by driving the lifting cylinder 18, and the height of the shaft center of the transmission 29 is adjusted. The four rocking cylinders 30 are individually driven to rock the frame 21 in the front-rear direction and the left-right direction so that the transmission 29 and the engine 39 have the same axis.

The conveyor chain 23 is moved by driving the air motor 26, and the transmission 29 is moved to the engine 39 side. Since the pallet 38 of the transmission 29 is moved by the two conveyor chains 23, even if the transmission 29 is inclined in the traveling direction, the inclination is corrected while contacting the engine 39. Further, the transmission 29 is moved to fit the shaft of the transmission 29 into the engine 39, and the transmission 29 and the engine 39 are connected. After that, the transmission 29 and the engine 39 are fixed by bolting or the like.

Since the transmission coupling device described above supports and centers the transmission 29 by driving the lifting cylinder 18 and the swing cylinder 30, the centering and coupling can be safely and easily performed by one worker. Can be done. Further, since the frame 21 is supported at two positions in the moving direction of the transmission 29 (the lifting cylinder 18 and the floating joint 20), the support for the movement of the load is reliable and the reliability is high. In addition, since no expensive equipment is used, the device becomes inexpensive.
