Description

  The present invention relates to a component assembling jig for assembling a plate member to a shaft member.

  Since the conventional component assembling jig does not include a guide plate which will be described later, the plate member assembled coaxially with the shaft member is displaced, and it is finally necessary to use a tool to align the center position. .

For example, Patent Document 1 describes a jig that adjusts the position in the horizontal and vertical directions when assembling a part that requires high accuracy.
Japanese Patent Laid-Open No. 9-298033

  An object of the present invention is to realize a jig that does not require adjustment of a position using a tool, and can easily align and assemble a shaft member and a plate member coaxially.

  In order to achieve the above-described object, the component assembling jig according to the present invention is a component assembling jig 40 for assembling the plate member 36a to the shaft member 37 as a component constituting the drive mechanism 39 of the valve unit 10. The body member 41 holding the shaft member having the spring 33 interposed on the outer peripheral surface thereof, and the body portion attached to the body member at symmetrical positions with respect to the shaft center of the shaft member, A guide plate 42 that contacts the outer shape of the spring and aligns the axis of the shaft member and the center of the plate member, and presses the plate member into the shaft member in a state of being aligned by the guide plate And a pressing plate 43 to be used.

  Preferably, the pressing plate includes a cam portion 44 that presses the guide plate, and a handle portion 45 for rotating the cam portion.

  ADVANTAGE OF THE INVENTION According to this invention, the adjustment of the position which uses a tool is unnecessary and the jig | tool which can align and assemble | attach a shaft member and a plate member coaxially easily is realizable.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The embodiment described below is an example as means for realizing the present invention, and the present invention can be applied to a modified or modified embodiment described below without departing from the spirit of the present invention.

[Valve drive mechanism]
The valve unit 10 of this embodiment is mounted on, for example, a beer filling device (not shown) called a filler that fills a plurality of empty cans continuously conveyed on a line with beer, sparkling beverages, or the like. .

  FIG. 1 is a front view (a), a cross-sectional view (b) taken along line ii of FIG. 1 (a), and a top view (c) of FIG.

  As shown in FIG. 1, the valve unit 10 is supported by the base member 1 via a support plate 12. A drive shaft 31 extending upward is rotatably connected to the arm portion 14b of the can mouth member 14. A lower portion of the drive shaft 31 is supported so as to be slidable with respect to the support plate 12 via a bearing 32. Further, the drive shaft 31 is urged downward by a spring 33 interposed on the outer peripheral surface of the drive shaft 31 and interlocked with the drive roller 34 attached to the central portion of the drive shaft 31 moving up and down. Driven up and down.

  A bearing member 31a is fixed to the upper end portion of the drive shaft 31, and an operating lever 39 for driving the valve unit 10 in the vertical direction is rotatably supported on the bearing member 31a.

  The operating lever 39 includes a link member 36 on which the drive roller 35 is supported, and a rotation shaft on which the link member 36 is fixed via a plate member 36a, and the link member 36 swings and rotates as the drive roller 35 moves up and down. 37, a link member 38 that converts the rotation of the rotation shaft 37 into a vertical movement, and a spring 37a. The link member 38 is connected to the upper end of the valve unit 10 to open and close the valve.

  That is, when the drive shaft 31 moves to the lower position P1, the can mouth member 14 comes into close contact with the inlet 2 of the container, and the liquid is injected into the container by opening the valve in this state. Further, when the drive shaft 31 moves to the upper position P2, the can port member 14 is separated from the injection port 2 of the container, the valve is closed, and the liquid injection is stopped.

[Jig configuration]
FIG. 2 is a front view (a) and a side sectional view (b) of the component assembling jig according to the embodiment of the present invention.

  The component assembling jig 40 of this embodiment is used when the operating lever 39 disassembled for maintenance or the like is reassembled.

  Specifically, as shown in FIG. 2, the component assembling jig 40 according to the present embodiment includes a resin material having an arc shape that matches the outer shape of the spring 37 a attached to the outer peripheral portion of the rotating shaft 37. The main body 41 and the main body 41 are attached to the main body 41 at positions symmetrical to each other with respect to the axis of the rotation shaft 37, and come into contact with the outer shape of the spring 37 a to A guide plate 42 that aligns the shaft center with the center of the hole 36b of the plate member 36a, and a pressing plate 43 that presses the plate member 36a in a direction to be inserted into the rotating shaft 37 while being guided by the guide plate 42. And having.

  The pressing plate 43 is formed with an arcuate cutout 43a and is moved in the axial direction by the cam 44 to press the plate member 36a. The cam portion 44 includes a handle portion 45 for rotating the cam portion 44 to press the plate portion 44, and a support plate 46 that extends from the main body portion 41 and supports the cam portion 44 eccentrically.

  The arc shape of the main body 41 and the notch 43 a of the pressing plate 43 are designed to be coaxial with the rotation shaft 37 attached to the main body 41.

[Assembly procedure]
Next, a procedure for assembling the plate member 36a to the rotating shaft 37 of the operating lever 39 using the component assembling jig 40 of the present embodiment will be described with reference to FIG.

  As shown in FIG. 2, when the rotating shaft 37 of the operating lever 39 is mounted on the arc-shaped portion of the main body 41 and the plate member 36a is mounted between the support plates 46, the axis of the rotating shaft 37 and the plate member Positioning is performed so that the center of the hole 36b of 36a matches. In this state, the handle portion 45 is operated and the plate member 36a is moved to the rotating shaft 37 side against the urging force of the spring 37a by the pressing plate 43 and inserted.

  In this manner, the parts can be assembled while the positioning of the rotation shaft 37 and the plate member 36a is facilitated.

  Thereby, the adjustment of the position using a tool becomes unnecessary and the position alignment at the time of assembling components can be performed easily.

It is the front view (a) which shows the valve drive mechanism of this embodiment, ii sectional drawing (b) of (a), and the top view (c) of (a). It is the front view (a) and side sectional view (b) of the jig | tool for component assembly of embodiment which concerns on this invention.
