Description

  The present invention relates to a general-purpose shim plate. More specifically, the present invention relates to a general-purpose shim plate used for adjusting the height and gap of a mechanical structure.

Adjustment of the height and clearance of the mechanical structure is performed by packing or laying a thin metal plate called a shim (Non-Patent Document 1).
These shims include those having a special dedicated shape (Patent Documents 1 and 2) and those that are not special in shape but used in accordance with the shape of the insertion space (Patent Documents 3 and 4).

However, not only the shims of Patent Documents 1 and 2 but also the shims of Patent Documents 3 and 4 need to be prepared in large numbers according to the place of use. For example, in the case of a crane vehicle, a bolt is fastened between a truck chassis and a crane frame, but they are not straight but somewhat wavy when viewed along the longitudinal direction because of the welded structure. For this reason, the gap height between the two members is different in some places, so insert a thickness shim according to the gap height, and after tightening the bolts, keep the truck chassis and crane frame parallel when viewed as a whole. To be. Even if the shim used in this way is a general quadrangle, it is necessary to prepare various types of shims having different vertical and horizontal dimensions depending on the insertion portion.
However, in order to do so, the inventory quantity increases and it takes time and effort for inventory management. For this reason, there is a problem that it leads to high costs.

  In view of the above circumstances, an object of the present invention is to provide a general-purpose shim plate that requires a small amount of inventory and can simplify inventory management.

The general-purpose shim plate of the first invention is characterized in that a plurality of shim pieces are connected to each other by connecting branches that can be separated or bent.
The general-purpose shim plate of the second invention is characterized in that, in the first invention, the plurality of shim pieces are connected in a multi-stage multi-row.
A general-purpose shim plate according to a third aspect is characterized in that, in the first or second aspect, the connecting branch is separable or bendable by a hand tool.
The general-purpose shim plate of the fourth invention is characterized in that, in the second or third invention, the plurality of shim pieces are also connected to a frame member using the connecting branch.

According to the first invention, a shim plate of any size and shape can be made by cutting or bending any shim piece among the plurality of shim pieces. For this reason, by preparing shim plates having the same dimensions and shape, it is possible to deal with various places of use, and the inventory quantity is small and inventory management can be simplified, so that the cost can be reduced.
According to the second invention, since the shim pieces connected in multiple rows and multiple stages have a high degree of freedom to cut or bend into arbitrary vertical and horizontal dimensions, it is easy to obtain a shim plate having a size and shape suitable for the place of use.
According to the third aspect of the invention, since the connecting branches connecting the shim pieces can be separated or bent by the hand tool, it is not necessary to use a special tool, and the shim plate can be easily manufactured.
According to the fourth invention, since the shim piece is also connected to the frame material, deformation of the shim piece based on external force can be suppressed by the frame material, and handling becomes easy.

It is a top view of the general purpose shim board concerning one embodiment of the present invention. (A) is a top view which shows the 1st example of use of the general purpose shim board A of FIG. 1, (B) is a top view which shows a 2nd example. (C) is a top view which shows the 3rd example of use of the general purpose shim board A of FIG. 1, (D) is a top view which shows a 4th example.

Next, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a general-purpose shim plate A in a state before use, that is, in a stock state.
Reference numeral 1 denotes a frame material (dot display portion in FIG. 1), 2 denotes a plurality of shim pieces, and 3 denotes a connecting branch (shaded display portion in FIG. 1). The shim pieces 2 are connected to each other by a connecting branch 3 and are also connected to the frame member 1. In the illustrated embodiment, each shim piece 2 has a rectangular shape and is arranged in a multi-stage multi-row with 5 rows and 4 rows. The frame material 1 connects four sides.

As the material of the shim plate A, an arbitrary metal such as a steel plate (for example, SS) or a copper plate, paper, plastic, or the like is used.
As for the thickness, an arbitrary thickness is used according to the purpose of use. Typically, a material whose thickness changes at intervals of 0.1 mm or a material whose thickness changes at intervals of 1 mm is used, but is not limited thereto. The shape of the shim plate A is basically a long rectangle or a regular rectangle, but is not limited thereto. The vertical and horizontal dimensions are typically 50 to 300 mm × 300 to 900 mm, but are not limited to these numerical values and are completely arbitrary.

  The shape of each shim piece 2 is basically a long rectangle, but may be another shape including a regular rectangle. The vertical and horizontal dimensions are typically 50 mm to 200 mm × 10 mm to 60 mm, but are not limited to these numerical values and are completely arbitrary. The number of stages and the number of columns are also arbitrary, and any number may be adopted. Further, the number of stages may vary depending on the column.

  In the illustrated embodiment, the frame member 1 is formed of four sides and surrounds a 5-stage 4-row shim piece group, but is not limited to this shape. For example, it may be only two sides facing each other or a certain side (longitudinal direction or short side direction). Further, it may be an L-shape connecting one side in the longitudinal direction and one side in the short direction.

The shim pieces 2 of each stage and the shim pieces 2 of each row are connected to each other by a connecting branch 3. The connecting branch 3 preferably has a thickness that can be easily separated or bent by a hand tool. In this embodiment, the connecting branch 3 has a width of 2 mm, but it may be smaller or thicker.
In addition, the number of connecting portions is two for the long sides of the shim piece 2 and one for the short sides and one for connecting to the frame member 1, but is not limited thereto.

  Pliers, scissors (for iron plate), chisel, etc. can be exemplified as hand tools for separating and bending the connection branch 3, and if these hand tools can be used for separation, there is no need to use a dedicated tool. Use value at the site (sim use site) increases.

Below, the usage method of the shim board A of this invention is demonstrated.
The shim plate A of the present invention is characterized in that it can be cut out or bent into a shim plate having an arbitrary shape from the initial multi-stage multi-row shape (state shown in FIG. 1).
Examples are shown below.

2A is an example of cutting out into five stages and two rows of shim plates B, and FIG. 2B is an example of cutting out into shim plates C of four stages and one row. In this way, it can be arbitrarily cut into large rectangles or quadrangles.
FIG. 3C is an example of cutting out into two rows and two rows, and is an example of cutting out into an elongated shim plate D in this way.
(D) of FIG. 3 is an example of the shim board E cut out in a shape similar to a horseshoe shape with a space for passing a bolt or the like.

  Although the example of said 4 types of shim board B-E was shown, these are representative examples, Comprising: It is not restricted to these. Of course, the greater the number of stages, the more complex shim plates can be cut out. Moreover, you may bend using hand tools, such as pliers, instead of cutting out.

  In the general-purpose shim plate A of the present embodiment, shim plates B to E having any size and shape can be made by cutting or bending any shim piece 2 out of a plurality of shim pieces as described above. . Therefore, by preparing a general-purpose shim plate A having the same dimensions and shape, it is possible to deal with various places of use, the inventory quantity is small, inventory management can be simplified, and the cost can be reduced.
