Abstract

PURPOSE:To enable a stabilized operation status without having dispersion of clearance values among connected members by calking a connecting pin top, while, keeping the required clearance between the linking stopper edge of the connecting pin and a connected member. CONSTITUTION:Plural number of connected members 3, 4 to be connected to each other are pierced with a connecting pin 2 provided with linking stopper edge 2a at its one end. The top 2b of the connecting pin 2 is processed with loose proof processing such as calking, while, holding a required clearance between the linking stopper edge 2a and the connected member 3. Accordingly, both connected members 3, 4 are formed with the required clearance and connected together rotation free.

Description

[Detailed Description of the Invention] What about industrial applications? ] The present invention relates to a +If movement connection method for connecting members, which rotatably connects a plurality of members to be connected using connection pins.

[Prior Art] Conventionally, when connecting the material to be connected to the rotatable shaft 1 at 11", as shown in FIG.
Pass through the connecting pin 2 that has been assembled, and connect one of the assembled materials 3 (hereinafter referred to as F connection A component 3) and the other...
1- of the connecting pin 2, and caulk the tip 2b of the connecting pin 2 protruding from the connecting part B 4 as shown in FIG. Connect B part 4 to Ij, and then apply a cling film IIi l
, the connection parts 3 and 4 of AB are forcibly separated to form a gap a, and this gap a allows connection A part 3 and connection B part 4 to connect so that they can rotate very smoothly. This resulted in a product as shown in Figure 4.

[Problem to be solved by the invention] In the conventional force, as shown in the figure, the control is simple, but on the other hand,
In order to move the connection A part 3 and the connection B part 4 as smoothly as possible, apply a wrap agent as described in 11f1 to force them apart, or sometimes tighten the connection pin 2 by caulking the part 4 to remove the looseness. It is necessary to forcibly create a gap a in the direction of the part 2', and this causes variations in the gap a in the culm, resulting in poor working condition f! 1 (-1:, operating crab, :) was inconsistent, and there was also a problem that the part 4 would fall off from the caulked portion 2' due to excessive wrapping.

"Steps to Solve Problem E" The present invention was devised to avoid the drawbacks of the previous two prior art examples, and it has been devised to avoid the drawbacks of the previous two conventional examples. A connecting pin with a locking edge is passed through the connecting pin, and a portion q, j i,
The tip of the connecting pin, which passes through the material to be connected and projects from the material to be connected, is formed so as to form and maintain a gap of 1, while the tip of the connecting pin protrudes from the material to be connected by caulking or the like.

[Example] Figures 1 to 3 show examples of devices implementing the present invention υ.
Give an example.

Figure 1 shows the main body of the device.
．． Alternatively, a pedestal edge 17 on which the B part 4 is placed is provided, and the part 3 of +iif is attached near the pedestal edge 17 with a screw 7
, 4 to the main body 1 to hold them in place.

At a suitable position of the pupil edge 17, a first pushing pin 6 is disposed in a part of the guide hole 18 provided in the main body l so as to be able to protrude and enter, and this pin 6 is always urged in the opposite direction. Spring l
O is placed between the base 6' of the pin 6 and the main body 1, and the piston 8 is housed under the pin 6 so as to be vertically movable. A third push-off pin 11 is disposed below the piston 8. push pin t
i is one end 12'' of a push-up cup 12 which is arranged so as to be swingable around a shaft 16 in a hollow space 19 of one main body l with its dome protruding from the dome of the guide hole 18 in 1111. It is placed on 1.

In the diagram 13, one end of the push cup 12" is applied with -1- force.
The spring 14 that is biased is a cam that resists the spring 13 and restricts the swinging of the push rod 12.

The other end 12'' of the push rod 12 is connected to the empty space 19.
A dial gauge 15 is derived from this and is supported on the main body 1 of the apparatus at one end 12'' with a weight of 1 g.

9 is an 11 female screw installed horizontally on the main body l, and the tip 9' of the screw 9 is
is adapted to press against a piston 8 disposed in the guide hole 18 so as to be vertically movable, thereby fixing the piston 8.

After passing the pin 2 from the F side, that is, from the component 3 side, placing it on the pupil edge 17 of the main body 1, and tightening the screw 7, it is inserted between the component holder 5 and the main body 1. cam 14
When rotated, the spring 13 pushes 1 and the bar 12 -
One end 12'' swings around the shaft 16 to push the first push pin 11 up.The pin 11 pushes the first push pin 6 through the piston 8. The connection pin 2 located at the pin 6H by 1-1 of this pin 6 is L-4L, and the edge 2a of the connection pin 2 abuts against the connection A part 3 [; At this point, the dial gauge 15 reads O, and then the cam 14 is rotated to connect the - end 12' of the push rod 12 to the spring 13. Resist and make it dangerous. (This descent

Jll and times of the gap a that you want to create between them).

Since the pusher cup 12 is displaced around the shaft 16, its displacement can be read with a dial gauge.

If the tip 12' of the pushing cup 12 is lowered, then

In addition, in the apparatus of the embodiment, other measuring tools such as a TiTi micrometer may be used in place of the dial gauge 15.

Also, do not caulk the tip 2b of the connecting pin 2.

Other methods such as laser processing (2) or electric r-beam may be used as well.

In the embodiment, a pair of materials to be connected are connected.
It is not impossible to apply the present invention to the case of connecting three or more members to be connected.

[Effects of the Invention] According to Unhappen II, there is no variation in the gap, so a product with an extremely stable operating state 71 of the connected materials can be produced, and the process of wrapping and rattling can be omitted. Unlike conventional methods, it does not require skill, and since it does not use a lapping agent, it is suitable for connecting materials that are less susceptible to contamination. be.
