Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an angle-adjustable receiving jig for stably supporting particularly heavy objects having a unique shape.

[0002]

2. Description of the Related Art As shown in FIG. 6, for example, when a non-rectangular mold body 1 having a narrow flat bottom of a press machine is stored, a sleeper 2 is applied to the inclined side surface of the mold body 1 so as not to fall down. There is. Further, when the attached pad 3 is mounted in the concave portion, the posture cannot be set vertically downward as it is by the suspending tool, so the posture is controlled by the lever 4.

[0003]

Therefore, it cannot be stored in a posture in which it is mounted on a press machine with its bottom surface horizontal, which not only makes the work troublesome but also tends to make the support state unstable. The installation work on the press machine also took time.

In view of the above points, the present invention has an object to provide an angularly adjustable receiving jig for stably supporting an object having a peculiar shape in a desired posture.

[0005]

In order to achieve this object, the present invention provides, according to claim 1, a pair of bases on both sides facing each other so as to place an object on the tip portion, and these bases. A pair of both-sided screw rods rotatably mounted coaxially on the base, a pair of both-sided receiving plates for both side surfaces of the object, and a pair of both-sided supporting arms whose upper ends are pivoted behind these receiving plates. In order that the pair of receiving plates on both sides can come into contact with both side surfaces in a vertical or backward tilted state, one of the lower ends of the receiving plate and the support arm is pivotally attached to a screw block screwed to a screw rod, The feature is that the other is pivotally attached to the base.

The angles of the pair of receiving plates on both sides are set by the rotation of the associated screw rods according to both side surfaces of the object to be supported, and the distance between the pair of bases on both sides is set according to the lateral width of the object. Place the bottom of the object on the tip of the base on both sides. As a result, the receiving plates abut on and support both side surfaces of the object while the position of the base is fixed by the weight of the object.

In order to securely fix the position of the base even when the load of the object to be supported on the base is insufficient, according to claim 2, the bases of the pair of bases on both sides are arranged in the direction orthogonal to the facing direction. A plurality of extending concaves and convexes are formed in the opposite direction, a base is installed, and a common installation table is formed in which a plurality of concaves and convexes that engage with the concaves and convexes are formed. In order to make it possible to support an object to be supported without providing a wide flat surface at the lower end, according to claim 3,
The base is common so that the object is placed in the central part.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An angle adjustable receiving jig according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3. This jig has a pair of box-shaped bases 10 on both sides on which an upper surface is opened and on which a support object such as the mold body 1 or the like is placed on the peripheral wall 10a, and coaxially arranged inside these bases. A pair of both-sided screw rods 11 rotatably attached, a pair of U-shaped receiving plates 15 that abut on both side surfaces of the object to be supported and have elastic sheets 15a adhered to the receiving surfaces thereof. Behind the receiving plates 15 facing each other, there are provided a pair of U-shaped support arms 17 of which both ends are pivotally attached to the rotary shaft 16 traversing between the side plates 15b on both sides thereof through holes.

Both ends of the threaded rod 11 are rotatably supported by bearings 12 mounted on a support plate 12a that crosses between the peripheral walls 10a. Further, a hexagonal rotation driving portion 11a that is rotated by a tool such as a spanner is formed at the rear end portion.

The side plate 17 at the lower end of one supporting arm 17
A rotary shaft 18 is mounted between a and between the side plates 15b at the lower end of the other receiving plate 15, and a screw block 19 which is screwed to the screw rod 11 with a nut portion is pivotally attached to the rotary shaft through its perforations. ing. The lower end of one receiving plate 15 and the lower end of the other supporting arm 17 are pivotally attached to the rotary shaft 16a that traverses between the peripheral walls 10a through their respective holes.

Each of these parts 11, 16, 16a, 15,
The dimensions of 17 and 18 and the mutual positional relationship allow the backing plate 15 to be tilted backward from the vertical state, and the base 10 can be tilted within this tilting range.
It is set so that the placement area of the support target is left in the forward area. The mounting surface of the base 10 in these regions is a horizontal surface formed by the upper surface of the peripheral wall 10a, but a horizontal plate may be provided on this surface or a solid portion.

Concavities and convexities 10b are formed on the bottom surface of the base 10 in a direction orthogonal to the facing direction of the receiving plate 15, and a plurality of lines are formed in the facing direction. By forming unevenness of a corresponding shape on the upper surface of the installation base 5 on which these bases are installed, the state in which the spacing between the bases 10 on both sides is adjusted according to the lateral width of the support target is the relationship between the unevennesses. The position is fixed depending on the combination.

When supporting the die main body 1, as shown in FIG. 3, one of the receiving plates 15 is formed depending on the inclined side surface 1a.
The rearward tilt angle (right side in the figure) is set by the rotation of the screw rod 11, and the other receiving plate 1 is set according to the vertical surface 1b.
5 is set vertically with its screw rod 11, and the base 10
Are separated from each other on the installation table 5 according to the lateral width of the mold body 1. The adjustment position of the screw rod 11 is locked by the lock nut 14. In this state, the die main body 1 is set from above by the suspending tool, and the bottom plate 1c is in a horizontal position like the mounting state on the press machine.
Abut and support. Next, the pad 3 is also mounted in the recess 1d from above vertically with a suspender.

It is also possible to fix the position of the base 10 by the weight of the mold body 1 without preparing the installation table 5 intentionally. However, if the lower end is an acute angle,
Alternatively, the base 10 can be fixed in position by providing the installation base 5 even if the base 10 does not contact the base 10.

FIG. 4 shows another embodiment. By eliminating the installation base 5 and using the base 20 in common, the degree of freedom in adjustment is reduced, but it is easy to carry and the bottom is not flat. Even objects can be supported on the base 20. The threaded rods 11 are respectively supported by bearings 23 attached to a support plate 21 which is separated at the central portion and traverses between the peripheral walls 10a.
For example, as shown in FIG. 5A, when the lower end of the object to be supported has an acute angle, this lower end is placed on the base 20, and one of the receiving plates 15 is set vertically to be contacted with a vertical surface. Since the separation distance between the 15 cannot be adjusted, the other receiving plate 15 is applied to the edges of the vertical surface and the inclined surface. FIG. 5B
As shown in FIG. 3, when the lower end portion of the object to be supported is circular, the lower end portion is placed on the base 20, and both receiving plates 15 are tilt-adjusted to be supported by their respective tangential contact surfaces.

[0016]

According to the first aspect of the present invention, both side surfaces of the object are angled according to the angle with the bottom surface of the object placed on both bases and the bases being fixed in position by their weights. In order to be supported by a backing plate that is adjusted to a vertical or backward tilting
Even if the bottom surface is placed horizontally, even an object with a shape that falls down can be supported in a stable state. Adjustment can be done with a tool such as an impact wrench. Adjustment in the mounted state is also easy. In particular, even heavy objects of various shapes such as molds of a press machine can be supported by a safe and simple operation in a posture suitable for use or storage.

According to the second aspect, the pair of receiving plates on both sides are prevented from engaging with the installation base and being displaced from each other in the separating direction.
Stable support is possible regardless of the shape. According to the third aspect, even if the lower end is an object having an acute angle or a circular shape, it can be stably supported on the base and can be easily carried.
