Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an article rotating table that rotatably holds an article, such as a radiator, that is large or has a complex shape that is difficult to stand on its own.

[Conventional technology]

BACKGROUND ART Conventionally, when assembling or repairing large or complex-shaped articles such as radiators, it has been difficult for workers to rotate the radiators in desired directions or to make them independent.

In other words, to install and remove the upper and lower tanks of the radiator, lay the radiator sideways on a pallet, screw in and remove the bolts on the upper side of each tank, then manually turn it upside down and screw on the bolts on the upper side. I'm putting it on and taking it off.

In addition, when soldering to repair core water leaks, etc., the radiator is placed on the floor and the worker sits on a chair while performing the soldering work. This placed a strain on the radiator, and there was also the risk of the radiator falling over.

Furthermore, in order to clean the core and fin parts, the radiator must be carried to a washing place and cleaned, which is a cumbersome task.

As other conventional technologies, for example,
The workbench of No. 43990 discloses a configuration in which the object is rotated along a plane that is almost parallel to the top plate serving as the work surface, but this configuration has the disadvantage that it is not possible to rotate or turn the article upside down outside the workbench. There is.

Furthermore, in the polishing table with an overturning device disclosed in Utility Model Application No. 55-115744, a structure is shown in which the article clamped within the frame is rotatably supported, but there is no operating section for controlling the rotation. Therefore, it has the disadvantage that it cannot be rotated to any desired posture.

Furthermore, the rotary workbench of JP-A No. 56-45388 discloses a configuration in which the workbench itself rotates, and the support stand for processing long objects of Utility Model Application No. 52-31993 is rotatable on the stand legs. Although a configuration in which a wheel is provided is disclosed, none of these is designed to perform work on a workbench while rotating an article.

[Problem that the invention attempts to solve]

This idea was devised in view of the above circumstances, and its main problem is to hold objects such as radiators that are large or have complicated shapes that are difficult to stand on their own in a fixed position outside of the base that is a workbench. To provide an article rotating table which is fixed and can be reversed or rotated up and down to simplify assembly and repair work, and allows an operator to perform the work from above the top plate.

[Means for solving problems]

In order to solve the above problems, this invention provides an article rotating table in which a rotatable article holding section is provided on the side of a base consisting of a workbench with a top plate horizontally supported above: (a) article holding section; (b) A rotating shaft is attached to the base so that the main body of the article holding part can be rotated in a direction substantially perpendicular to the direction in which the top plate part extends. (c) the door section faces the article holding section main body at a predetermined distance and is interlockably connected to the main body of the article holding section; (d) providing the door with a pressing part that moves forward and backward in a direction toward or away from the article holding part main body, and is capable of pinching the article between it and the opposing surface of the article holding part main body; We are taking technical measures.

[Effect]

A radiator or other article is sandwiched between the article holding section main body and the door section, and the article is held under pressure by adjusting the width with the pressing section.

The main body of the article holding section is rotatably supported on a base consisting of a workbench via a rotating shaft, and by operating the operation section, an object can be held in the above-mentioned clamped state in the direction in which the top plate of the workbench extends. It can be rotated at a desired angle in a direction substantially perpendicular to the , or it can be turned upside down.

〔Example〕

Hereinafter, a preferred embodiment in which the article rotating table according to the invention is used as a repair jig for a radiator will be described with reference to the drawings.

The article rotating table 1 shown in FIGS. 1 to 4 includes an article holding section main body 7 and a door section 8 on a base 2 forming a work table.
The article holding section is rotatably provided.

That is, the base 2 has a substantially rectangular desk shape, and a ladder section 11 for climbing up to the top plate section 2A is attached to the opposite side of the position where the article holding section main body 7 is disposed.

A handrail portion (not shown) may be provided along the ladder portion 11.

The top plate part 2A of the base 2 is horizontally supported at an upper position by support pillars provided at the four corners, and is used as a work place (scaffolding) for workers to stand on, and is provided with anti-slip means. For example, the top plate portion 2A may be formed of expanded metal.

Furthermore, if a protective frame (not shown) is erected at the side end of the top plate part 2A, it is preferable for safety to prevent the worker from falling, and since the top plate part 2A consists of a horizontal surface, it is safe to use during soldering work etc. Chairs etc. may be installed as appropriate.

An article holding section main body 7 is rotatably attached to the front side of the base 2 via a rotating shaft 75.

The rotating shaft 75 is configured to protrude inwardly (toward the base 2 side) from the front center of the main body 7 of the article holding section, is supported by the base 2, and is connected to the handle section 5 (in this embodiment, the steering shaft 75 will be described later). configuration via device 4)
It is supported on one side by the bearing part.

Further, the article holding section main body 7 has two upper and lower flanges 7A and 7B whose tips protrude in the extension direction on a wall surface having a generally U-shaped cross section, and are open in the vertical direction and outward.

A plurality of (two in this embodiment) pin hole groups 71, 72, .
... has been drilled.

A door portion 8 is pivotally attached to the distal end side of the article holder body 7, and is configured to open and close the outer open portion of the article holder body 7.

This door portion 8 has a shape in which ribs 8A, 8B are protruded along both upper and lower ends of a plate-like wall surface, and pin hole groups 71, 72 are formed in pairs on both sides of the ribs 8A, 8B. A pair of pin holes 81 are bored at intervals that match the .

The pivoting structure between the door section 8 and the article holding section body 7 is achieved by aligning the pin holes 81 on the door section 8 side with the pin holes at appropriate positions on the article holding section main body 7 side. , one side is penetrated by a locking pin P and pivotally attached.

Therefore, by penetrating both sides with locking pins P, P, the article holding section main body 7 and the door section 8 can be fixed and the radiator R can be held.

This door portion 8 is provided with a pressing portion 9 and is capable of being screwed forward and backward in the thickness direction (toward the main body of the article holding portion).

The pressing portion 9 has a plate shape, and a pair of pressing rods 91, 91 are rotatably attached to the back surface thereof.

This pushing rod 91 extends substantially horizontally from the back surface of the pressing portion 9, and has a thread carved on its outer peripheral surface.

On the other hand, a nut portion 82 for receiving the pushing rod 91 is projected approximately horizontally from the inner surface of the door portion 8, and is threadedly engaged with the screw of the pushing rod 91 to allow the pressing portion 9 to move forward and backward.

In order to rotate this pushing rod 91, for example, a handlebar 92 (see Fig. 3) having an insertion hole in the center is required.
and insert the push rod 9 into the insertion hole of the handlebar 92.
It is sufficient to use a method such as inserting the tip of 1 and rotating it.

In addition, 83, 83 are the nut parts 82, 82 of the door part 8.
It is a support cylinder part that communicates with and extends to the opposite side to hold and guide the pushing rod 91, and C and C are the inner surface of the door part 8 and the article holding part main body 7 opposite thereto.
It is a rubber pad fixed to the inner surface as a cushioning material.

The article holding section main body 7 and the door section 8 configured in this manner are integrally interlocked in a direction perpendicular to the extending direction of the top plate section 2A by an operation section 5 provided on the base 2. It is rotated.

In this embodiment, the operating section 5 includes a handle section 6 consisting of a handle shaft 61 having a circular handle 60 at the tip and bearing on a base;
The steering device 4 changes the direction of the rotational force input from the handle shaft 61 by 90 degrees and transmits it to the rotating shaft 75 that holds the article holding section body 7.

The steering device 4 may have a worm pin structure if it is a mechanism that changes the direction of rotational force approximately at right angles;
A mechanical structure such as a bevel gear structure or a structure using fluid pressure such as an oil pump type may be used.

In addition, since the base 2 consists of a rectangular desk shape,
If the handle portion 6 is disposed on one side, the article holding portion main body 7 can be disposed on the orthogonally adjacent side.

In this embodiment, as an example of the steering device 4, FIG. 4 shows a configuration using a worm pin type.

The steering device 4 includes a handle shaft 6 inside a casing 40 which is fixed to the back side of the top plate portion 2A of the base 2 and whose four corners are supported by support legs 3.
A first bearing housing 41 for bearing the rotary shaft 75 and a second bearing housing 42 for bearing the rotating shaft 75 are built in.

A worm W is engraved on the handle shaft 61, and a pin P2 is fitted into the lever L of the rotating shaft 75 via a bearing (not shown). A known configuration is adopted in which the pin P2 slides to rotate the rotating shaft 75.

As a result, the worker operates the circular handle 60 from the top plate section 2A of the base 2, which is the work place, to rotate the radiator R held by the article holding section main body 7 and the door section 8 via the rotating shaft 75. be able to.

Further, the steering device 4 or the circular handle 60 may be provided with reverse rotation prevention means.

That is, when it is desired to fix the radiator R held by the article holding part main body 7 or the door part 8 at any angle other than vertically, the rotating shaft 75 is prevented from freely rotating due to the weight of the radiator R itself. A locking configuration may be added.

For example, the rotating shaft 75 may be provided with a gear mechanism to prevent reverse rotation, a lock or braking mechanism may be provided to restrict the rotation of the rotating shaft 75 itself, or the circular handle may be fixed to the base 2 using a chain (not shown) or the like. It may be fixed to

Further, in the above embodiment, since the base 2 is rectangular and the handle portion 6 and the article holding portion main body 7 are disposed orthogonally to each other, the steering device 4 uses a configuration in which the rotational force is perpendicular to each other. However, if the shape of the base 2 is different or the position of the handle portion 6 is different, a mechanism for converting the angle to a corresponding angle may be used.

Furthermore, when the handle portion 6 and the rotating shaft 75 are 180 degrees, that is, on opposite sides, the handle shaft 61 and the rotating shaft 7
5 may be the same, and there is no need to provide a configuration for changing the rotation direction. However, in this case, a bearing housing for bearing the handle shaft 61 (namely, the rotating shaft 75) may be formed on the base 2.

Further, the handle portion 6 does not need to be configured to apply rotational force to the rotating shaft 75. For example, the rotating shaft 75 is rotated by a separate rotational drive means, and the handle portion 6 is configured to control the rotation or rotation angle of this rotational drive means. It may be an operating lever, a switch, etc. for control.

Next, a case will be described in which a radiator repair work is performed using the article rotating table 1.

First, the piping (JOINT part) and mounting bolts of the radiator mounted on the vehicle are removed, and the radiator is transported to the article carousel 1 while being lifted by a factory crane.

On the other hand, one pin P that fixes the door section 8 of the article rotating table 1 and the article holding section main body 7 is removed, and the door section 8 is left open.

Then, the radiator R suspended by a crane is set so that its center (center of gravity) is located at the center of the article holding section main body 7.

Next, the door portion 8 is pivoted in the closing direction, and the pin P is inserted and fixed to the article holding portion main body 7.

At this time, depending on the width (thickness) of the radiator R,
Remove the left and right pins P, P, move the door part 8 back and forth in the width direction, align the pin hole 81 with the optimal position of the pin hole group of the article holding part main body 7, and remove the pins P, P.
It can be adjusted by locking it.

Then, move the push rods 91, 91 to the handlebar 92.
The radiator R is rotated and advanced by the pressing part 9, and the radiator R is pressed by the pressing part 9 and held between the main body 7 of the article holding part.

As a result, the radiator R is clamped and removed from the crane.

The radiator R, which is thus held in the hollow position as shown in FIG. 3, is operated by an operator from the floor or from the top plate portion 2A of the base 2.

Here is an example of radiator repair work:
Examples include cleaning the core and fins, repairing water leaks in upper and lower tanks, repairing core water leaks (soldering), and disassembling repairs.

That is, remove the upper and lower tanks of radiator R.

This removal area (same for other work areas)
is located below, turn the circular handle 60 to rotate the handle shaft 61 and rotate the steering device 4.
The rotational force is transmitted to the rotating shaft 75 located at an orthogonal position through the rotating shaft 75, and the article holding section main body 7 to the door section 8 holding the radiator R are rotated and turned upside down to carry out the work.

Next, the entire radiator, water pipes, upper and lower tanks, etc. are washed with steam or high-pressure hot water (90°C), and then dried with hot air.

In addition, we repair water leaks in the upper and lower tanks, fix water leaks in the core, and solder the solder joints, which requires a long time.

Then, after replacing the seals and packing as necessary and assembling the upper and lower tanks, we conducted a test with the pressure (heat) raised during normal operation of the vehicle by circulating hot water at high pressure to detect water leakage from radiator R. Do a test.

After the test is completed, paint is applied to the rusted areas as necessary to complete the repair work.

After completing this work, suspend the radiator R again on a crane, etc., pull out one of the locking pins P, open the door 8, remove the radiator R, mount it on the original vehicle, and reconnect the piping to the engine. That's fine.

[Effect of idea]

The article is held on the outside of the base that serves as the workbench, and rotates along the side of the base in a direction approximately perpendicular to the direction in which the top plate extends, so that the worker cannot place the item on the top of the workbench. You can work in a comfortable position, and there is no need to take an unreasonable posture.

In addition, the article can easily change direction by controlling the operating section, improving work efficiency, and does not require any manual effort to change direction.

Furthermore, workers can perform tasks such as soldering, attaching and detaching parts, and cleaning at the same location.

In particular, compared to conventional methods, this method is extremely beneficial as it significantly shortens repair and other work time, reduces manpower, and prevents occupational accidents (low back pain, strained back, etc.) caused by handling heavy objects.

Furthermore, if a crane is used in combination, articles can be easily held between the article holding section main body and the door section, resulting in further labor savings.
