Description

[Detailed explanation of the invention] This invention is a hose for hydraulic, pneumatic, and power supply.
Tools that require cable installation (hydraulic clamps, hydraulic path joints, manipulators, etc.)
It belongs to the technical field of push/pull devices for pushing and pulling.

Among various tools, there are many that use hydraulic or pneumatic power as a power source, or that require electric power for power or control, but among them, such as hydraulic clamps, In the case of tools that are not fixed and are used while being moved as appropriate,
Processing and handling of hoses, cables, etc. becomes extremely troublesome.

For example, in the hydraulic clamp push/pull device 100 shown in FIG.
In this case, for example, the hydraulic hose 104 is suspended from a nearby fixed wall 105 with a spring 106.
The actual situation is that 04 is being processed.

In this case, a large space is required to handle the hydraulic hose, there is a risk of damage due to interference with nearby structures, the hydraulic hose is prone to localized fatigue failure due to severe vibration and acceleration, and the appearance is I don't like it either. In addition, it is almost impossible to arrange, for example, a control cable for connecting to a limit switch along the drive band, even though it is thick and has excellent rigidity and strength, such as a hydraulic hose.

There is also the problem that the sprocket gradually rotates due to the inertial force acting on the drive band with severe acceleration, causing the clamp to move.

In order to solve the above problems, the present invention is constructed as follows.

That is, a guide groove is formed in the main frame for attaching tools, etc., a guide part for the tools, etc. is inserted into the guide groove so as to be able to move forward and backward, and a drive device is attached to the side end of the main frame so that it faces the end of the guide groove. The drive band of the drive device is composed of a single-fold chain that can be bent only in one direction, and is housed in the casing, and the starting end of the drive band is fixed to the casing, and the starting end side part is folded back into a U shape. By introducing the terminal end side portion of the drive band into the guide groove through the direction switching guide part, connecting the terminal end to the guide part of a tool, etc., and driving the U-shaped folded part of the drive band up and down with the driving means, The terminal end of the drive belt is moved forward and backward to allow tools etc. to be driven forward and backward along the guide groove,
Some devices are characterized in that a cover is attached to the drive band, and a guide path for guiding a hose or the like is formed in the cover.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a die fixing plate 1 of a press machine slide.
1 shows a bottom view of the mold 2 fixed by two sets of hydraulic clamps 3 on the left and right sides.

The clamp 3 has its guide portion 3a slidably inserted into the guide groove 4, and its position can be adjusted in the left-right direction at the end of the guide groove 4 by a drive device 5 attached to the side end of the mold fixing platen 1. It's getting old.

The drive device 5, as shown in FIGS. 2 to 5,
Drive band 6 and sprocket 7 as a lifting/lowering drive device
, a driving means 8 , a guide 9 , a direction switching guide 10 , and a casing 11 .

The drive band 6 has idlers 14 pivoted on both sides of the connecting plate 13 of the steel chain 12, and has a breakage prevention device 15 with a U-shaped cross section corresponding to the length of the connecting plate 13 on the outer surface side that does not mesh with the sprocket 7. The end surfaces of the adjacent ones are brought into contact with each other, thereby allowing the structure to be bent inward.

Driving means 8 for raising and lowering the sprocket 7
consists of a support block 16, a threaded shaft 17, a guide rod 18, a speed reducer 19, and a motor 20. The sprocket 7 is pivotally supported on the support block 16, and the threaded shaft 17 and the guide rod are attached to the support block 16. 18 is inserted and guided vertically, and the support block 16 can be raised and lowered by a motor 20 via a hexagonal nut 21 and a coil spring 22. That is, as shown in FIG.
2 is externally mounted on a screw shaft 17, and a hexagonal nut 21 is restrained by a support block 16 so as not to rotate.

On both sides of the sprocket 7, a pair of guide tools 9 having a U-shaped cross section are installed vertically in the casing 11, and the free end edges of the guide tools 9 are brought into contact with the idler ring 14 of the drive band 6 from the outside. is restrained so that it does not bend outward.

The driving band 6 has its terminal end fixed to the casing 11 and is introduced into the guide groove 4 through the direction change guide section 10, and its terminal end is fixed to the clamp 3 within the guide groove 4.
The guide section 3a is connected to the guide section 3a. The direction change guide section 10 is composed of a J-shaped guide wall surface 26 on the lower side of the guide block 25 and a J-shaped portion of the guide tool 9, and changes the direction of the drive band 6 from the vertical direction to the horizontal direction in a curved manner. It is designed to do so.

As shown in FIG. 5, the drive band 6 introduced into the guide groove 4 from the direction switching guide part 10 is free to move freely even when its idler ring 14 is restrained by the guide wall surface 4a of the guide groove 4 and compressed. Does not bend.

As is clear from the above structure, when the sprocket 7 is raised by the drive means 8, the sprocket 7 engaged with the chain 12 rotates at a low speed, the drive band 6 is retracted into the casing 11, and the clamp 3 is moved to the right. You will have to move in that direction. When the sprocket 7 is lowered, it is drawn out from within the casing 11 in the opposite manner to the above, and the clamp 3 is moved to the left. Since the impact when the clamp 3 collides with the mold 2 is absorbed by the elastic deformation of the compression coil spring 22, the threads of the screw shaft 17 and the nut 21 are not damaged, and the drive band 6 is held in tension by force.

Next, in order to guide the hydraulic hose 24 for supplying and discharging hydraulic pressure to and from the hydraulic clamp 3 along the drive band 6, the one-sided bending prevention device 15 is also used as a cover device 27, and between the cover device 27 and the chain 12. The hydraulic hose 24 is introduced into the introduction path 28 formed in the
The terminal end of the hydraulic hose 24 is connected to the oil passage to the hydraulic cylinder of the clamp 3, and the starting end of the hydraulic hose 24 is connected to a hydraulic pressure supply port formed in the guide block 25.
Hydraulic pressure can be supplied from a hydraulic pressure supply device (not shown).

Incidentally, in place of the drive belt 6, it is possible to use a single-fold chain 12A shown in FIG. 6 with a cover member 27A attached thereto.

Furthermore, instead of the driving band 6, a steel band plate having a curved cross section may be used.

Further, as shown in FIG. 2, a limit switch 29 for detecting the forward and backward positions can be attached to the clamp 3, and the cable 30 thereof can be guided into the guide path 28 together with the hydraulic hose 24.

In addition, the sprocket 7 can be moved up and down using a cylinder (hydraulic/air) as the drive means 8.

However, the push-pull device for tools, etc. of the present invention is not limited to the above-mentioned clamp, but can also be used as a push-pull device for exchanging the mold of an injection molding machine between a conveyor cart and a molding machine, and also for the hydraulic pressure of hydraulic equipment. It can be applied to a push-pull device for connecting and separating a joint in a supply path, and also to a push-pull device for a manipulator driven by hydraulic pressure or compressed air.

Since the present invention is configured as described above, it has the following effects.

(1) Tools, etc. are moved forward and backward by driving the drive band with a drive means, and a path for guiding hoses, etc. is provided on the drive band with a cover, so hoses, etc. can be guided along the drive band. They are arranged neatly within the road and are well protected by covers.

In particular, the drive device is covered with a casing, and the drive band, hoses, etc. are neatly placed inside the casing.
Not only can it be accommodated compactly, but the structure can be simplified because the drive device also serves as a guide path.

Therefore, the trouble of processing and handling the hose, etc. is eliminated, the appearance is neat, and the durability of the hose, etc. is significantly improved.
