Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to a mechanical parts assembly device that allows mechanical parts used in various electrical products, OA equipment, and other devices to be easily assembled.

[Conventional technology]

Conventionally, mechanical parts used in various electrical products, OA equipment, and other devices have been assembled using various assembly devices, but the above assembly devices are generally expensive assembly robots, etc. If assembly robots and the like could not be introduced, it would have to be done manually.

[Problem that the invention attempts to solve]

However, manual work was extremely inefficient, and the work of checking for mistakes such as omissions in assembly was time-consuming. This invention attempts to eliminate the above-mentioned drawbacks of the conventional example, and aims to provide an assembly device for mechanical parts that can eliminate the burden of assembling mechanical parts and the difficulties in inspection.

[Means to solve the problem]

That is, the machine parts assembly device of this invention includes a base frame in which a plurality of accommodation holes are formed corresponding to the parts to be mounted on the machine parts, a transparent bottom plate attached to the bottoms of the accommodation holes, and the base frame. an assembly device main body provided with an accommodation guide installed upright on the side of the frame; and a sheet held outside the bottom plate that attracts mechanical parts housed in the accommodation hole that can be attracted by magnetic force through the bottom plate. It is characterized by having a shaped magnet.

[Effect]

Since the device for assembling mechanical parts of this invention is constructed as described above, it is possible to check the storage status of mechanical parts through the transparent bottom plate during the assembly work of mechanical parts to various devices.

【Example】

An embodiment of the mechanical parts assembly device of this invention will be described below with reference to the drawings. 1 and 2, the mechanical parts assembly apparatus of the embodiment first includes a base frame 11 in which a plurality of accommodation holes 13 are formed corresponding to the parts to which mechanical parts are mounted, and The assembly device main body 1 is comprised of a transparent bottom plate 15 made of plastic, tempered glass, etc., attached to the bottom of the base frame 13, and a storage guide 17 erected on the side surface of the base frame 11. Second, it is provided with a sheet-like magnet 2 which is held outside the bottom plate 15 and which attracts mechanical parts accommodated in the accommodation holes 13 through the bottom plate 15 that can be attracted by magnetic force. The magnet body 21 constituting the sheet-shaped magnet 2 is made of a material such as a rubber magnet or a plastic magnet that can be formed into a sheet shape, and its surface is magnetized to form a predetermined magnetic field. This magnet body 21 has a highly rigid support plate 23 on the back side.
is lined with. The assembly device described above is used to attach a mechanical component consisting of a coil spring 31 to a mounting portion 3 of the mechanical component shown in FIG. The mounted part 3 is an example of a keyboard of OA equipment,
A lifting member (guide chip) 41 that supports a key (not shown) in a vertically movable manner;
1 and a base plate 45 from which the lift guide 43 is protruded. The coil spring 31 is fitted into the elevating member 41 so as to normally urge the key to the upper end of the elevating position. The assembly device is used in the work of fitting the coil spring 31 into the lifting member 41. At this time, the mounted portion 3 is attached to the lifting guide 4.
It is assumed that the elevating member 41 is attached to 3. With the sheet-like magnet 2 in contact with the back surface of the base frame 11, the coil spring 31 is placed on the base frame 11 of the assembly device, and the entangled coil spring 31 is accommodated in the plurality of accommodation holes 13 while being loosened. At that time, the accommodation guide 17 erected on the side of the base frame 11
While preventing the base frame 11 from falling off, the base frame 11 is sequentially accommodated in the accommodation hole 13 by swinging. At this time, each coil spring 31 is accommodated in the accommodation hole 13 while being attracted thereto. The coil spring 31 is manually fitted into the accommodation hole 13 in which the coil spring 31 is not accommodated.
At the stage when the entire housing is completed, even if the base frame 11 is turned over, the coil spring 31 is attracted by the sheet-like magnet 2 and is held within the housing hole 13. Next, the manner in which this mechanical parts assembly device is used will be explained. As shown in FIG. 4, this base frame 11 is turned over,
When the base frame 11 is placed over the mounting portion 3 with the coil spring 31 held downward in the accommodation hole 13, the coil spring 31 is fitted along the outer periphery of the corresponding lifting member 41. After that, the base frame 11
When the magnet on the sheet attached in contact with is removed, the coil spring 31 held downward in the accommodation hole 13 is released from the suction hole into the accommodation hole 13, and the base frame 11 is removed from the attached part 3. It remains attached to the elevating member 3 even if the elevating member 3 is moved.

[Effect of the idea]

As described above, according to the mechanical parts assembly apparatus according to the present invention, it is possible to easily assemble a large number of mechanical parts, so that the burden of assembling the mechanical parts can be significantly reduced. Additionally, when assembling mechanical parts into various types of equipment, the housing status of mechanical parts can be confirmed through the transparent bottom plate, making it easy to grasp the housing status and eliminating inspection difficulties. .
