Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a structure for adjusting the position of parts attached to a main body of an apparatus, and particularly to an adjustment structure configured to easily adjust the position after assembly of the apparatus.

[Conventional technology]

In various types of devices, misalignment of parts that form part of the device often affects the performance of the device as a whole. This point also applies to a top-pan type weighing device.

FIG. 3 shows a load cell type weighing device having an upper plate. In this device, 10 is a substantially L-shaped support member, the bottom of which is fixed to the weighing device body with bolts 11a and 11b. 1
2 is also a bolt 13 for this support member 10.
This is the load cell body fixed with a and 13b. Another support member 14 is attached to this load cell main body 12 with bolts 15a, 15b, and further a plate support 17 is attached to this support member 14 with bolts 16a, 16b. Finally, the upper plate 18
The structure is such that the

[Problem that the invention attempts to solve]

The configuration shown in Figure 3 belongs to the simplest type of mounting structure for the load cell body, and the ones currently on the market have complicated structures such as attaching members to protect the instantaneous load applied to the load cell body. It's summery. Therefore, even if the installation of each member is slightly incorrect, there is a risk that the installation structure of the entire device will be significantly incorrect. Furthermore, the mounting position of each member changes slightly depending on how the bolts are tightened, and since there are a large number of bolts, it is virtually impossible to install the parts without any errors.
Furthermore, it goes without saying that as the configuration becomes more complex, the influence of misalignment of each member increases.
Therefore, it is necessary to adjust the mounting position several times when assembling the device, and a special jig may be used for this adjustment. However, even with such adjustments, it is inevitable that some deviation will occur during final assembly. Particularly in the case of a top plate type weighing device, this deviation is noticeable in the top plate which is the final assembled part, and for example, a situation may occur where the top plate 18 is tilted as shown by reference numeral 18'.

[Means for solving problems]

The present invention was constructed in view of the above-mentioned problems, and three position adjustment bolts are arranged on or near a predetermined virtual circle centering on the bolt for attaching the component, and This structure is characterized in that a hole for operating a position adjustment bolt is formed, and the top of the position adjustment bolt is formed larger than the operation hole.

[Effect]

As described above, this invention arranges three position adjustment bolts around the bolt for attaching parts,
A hole for operating the position adjustment bolt was formed for the part to be installed, and the top of this position adjustment bolt was made larger than the operation hole, so there was no chance of the part being installed in the wrong position. If so, after completing the installation of this part, raise and lower each position adjustment bolt through the operation hole of the installed member. Since the top of each position adjustment bolt is formed larger than the operation hole, the member is pushed up as the bolt rises, thereby adjusting the position of this part.

〔Example〕

Embodiments of the present invention will be specifically described below with reference to the drawings.

FIGS. 1 and 2 show a structure in which a plate support is attached to a support member attached to the load cell main body side.

Reference numeral 1 denotes a plate receiving member attached to the support member 14, and is fixed to the support member 14 by means of attachment means such as bolts 17.
Reference numeral 2 designates a main bolt for attaching the plate holder 3 at the center of the plate holder mounting member. The pan support 3 is basically attached to the pan support mounting member 1 with this one main bolt. In addition, three position adjustment bolts 4a, 4b, and 4c are positioned at the vertices of an equilateral triangle so as to be positioned on a predetermined imaginary circle with the main bolt 2 at the center of the plate receiving mounting member 1, which is approximately circular in plan. They are each located so that they can be used. The position adjusting bolts 4a to 4c are configured such that when they are completely screwed into the dish receiving member 1, the top surfaces thereof are flush with the upper surface of the dish receiving member 1 or are recessed below this upper surface. Reference numeral 5 denotes a hole for operating a position adjustment bolt formed in the plate support 3, and is formed corresponding to the arrangement position of each position adjustment bolt. The inner diameter of the operating hole 5 is made smaller than the diameter of the top of the position adjusting bolts 4a to 4c within a range that allows the position adjusting bolts 4a to 4c to be operated (rotated). In other words, the top peripheral edge of each of the position adjustment bolts 4a to 4c is configured to come into contact with the back surface of the plate holder 3.

In the above configuration, including FIG. 3, when the load cell main body 12 and each support member 10, 14 are attached during assembly of the device, errors occur in the attachment of each component. For this reason, if the pan holder 3 is attached to the support member 14 as it is, a situation will occur where the pan holder 3 will be tilted. In this case, after mounting the plate holder 3, each position adjustment bolt is rotated from the upper part of the plate holder 3 through the operation hole 5 using a bolt rotation tool such as a screwdriver. As a result, each position adjustment bolt moves up and down in accordance with its rotation. As mentioned above, the diameter of the top of each position adjustment bolt is larger than the inner diameter of the operation hole 5, so when the position adjustment bolt is raised, the top of the position adjustment bolt touches the back surface of the pan holder 3. Push up. Three position adjustment bolts are arranged around the main bolt 2, so by raising and lowering each position adjustment bolt 4a to 4c as appropriate, the pan holder 3 can be adjusted.
can adjust its mounting condition.

In this operation, the position of the pan holder can be adjusted sufficiently by a small gap between the threaded portions that occurs when the main bolt 2 is screwed into the pan holder mounting member 1, and by the elasticity of the main bolt 2 itself.

Although the present invention has been described above using the members constituting a load cell weighing device as an example, it is not limited to this, and can be applied to adjusting the mounting position of parts in various devices.

〔effect〕

As described above, the present invention arranges three position adjustment bolts on or near a predetermined virtual circle around the bolt that attaches a member that constitutes a part of the device, and The hole for operating the position adjustment bolt is formed to correspond to the arrangement part of the position adjustment bolt, and the top of this position adjustment bolt is formed larger than the operation hole.
After the member is attached, the position of the member can be adjusted freely by operating each position adjustment bolt from the surface of the member.
