Abstract

(57) [Summary] [Purpose] To make it easy to attach floating balls to the lever. [Constitution] A motor 54 is installed in a box 52, and a cup 58 is attached to a shaft of the motor 54 via a joint 56. Floating ball 2 in the recess 60 of this cup 58
Two are engaged. The lever 24 is slightly screwed into the lever mounting hole of the floating ball 22 so that the floating ball 22 can be attached to the cup 5 or the like.
By rotating the motor 54 against 8, the floating ball 22 is rotated, and the lever 24 is deeply screwed into the lever mounting hole of the floating ball 22. [Effect] Floating balls can be attached to the lever very easily, and significant labor saving can be achieved. In addition, the assembly work efficiency of the ball tap is significantly improved.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a float ball tightening machine used when assembling a ball tap float ball to a lever.

[0002]

[Prior art]

 A water tank, for example, a flush toilet tank is equipped with a ball tap, and water is supplied so that the water level in the water tank reaches a predetermined water level.

An example of a conventional ball tap will be described with reference to FIG. 3. A partition 12 is provided inside the valve box 10, and a water supply port 14 side and an outflow port 16 side are separated from each other. An opening 18 is provided in the partition portion 12, and a valve body 20 can be seated on a peripheral portion (valve seat 18a) below the opening 18. The valve body 20 is operated by a lever 24 with a floating ball 22 and an arm portion 26. The lever 24 is pivotally fixed to a lever mounting portion 28 integral with the valve box 10 via a pin 30. The arm portion 26 is pivotally fixed at its proximal end side to the valve box 10 and an arm mounting portion 32 which is integral with the arm portion 26 through a pin 34, and a screw shaft 36 for adjusting the water level is provided at the tip end side of the arm portion 26. Has been. An adjusting nut 36a and a lock nut 36b are screwed to the screw shaft 36.

In this ball tap, when the water level in the low tank rises, the floating ball 22 rises due to buoyancy, and the valve body 20 abuts the valve seat 18a of the opening 18 (the lower edge of the opening 18) with a strong force. , Water is stopped.

Further, when the water level in the low tank drops, the floating ball 22 descends, the valve body 20 separates from the valve seat 18a, and water is passed. A part of this water is directly supplied from the water discharge port 40 into the raw tank, and the other part is supplied to the hand washing pipe 42.

By the way, a male screw is engraved on the tip of the lever 24, and the tip of the lever 24 is screwed into the lever mounting hole of the synthetic resin floating ball 22.

[0007]

[Problems to be solved by the device]

 Conventionally, all the work of screwing the lever 24 into the floating ball 22 has been a manual work, so there is a problem that the work efficiency is poor.

[0008]

[Means for Solving the Problems]

 The floating ball fastening machine of the present invention comprises a cup that engages with the tip of the floating ball, and a drive device that rotates the cup around its axis.

[0009]

[Action]

 To screw the lever into the float using the float clamp of the present invention, first touch the tip of the lever to the lever mounting hole of the float and rotate the float once to several times (for example, twice). Lightly fasten. Next, the floating ball is applied to the cup and the cup is rotated. Then, the float is rotated by the force of the driving device, and the lever is screwed deeply into the float.

[0010]

【Example】

 An embodiment will be described with reference to FIGS. FIG. 1 is a perspective view of the floating ball tightening machine 50, and FIG. 2 is a sectional view showing a usage state.

A motor 54 is installed in the box 52, and a cup 58 is attached to the shaft of the motor 54 via a joint 56. The leading end of the floating ball 22 is engaged with the recess 60 of the cup 58. The lever 24 is slightly screwed into the lever mounting hole 22a at the rear end of the floating ball 22, and by floating the floating ball 22 against the cup 58 and turning the motor 54, the floating ball 22 is rotated and the floating ball 22 is rotated. The lever 24 is deeply screwed into the lever mounting hole.

As described above, since the floating ball 22 is rotated by the motor 54, the work efficiency of assembling the floating ball 22 and the lever 24 is significantly improved. It should be noted that a soft synthetic resin (for example, trade name DURACON) is suitable for the cup 58. With such a synthetic resin, the floating ball 22 is less likely to slip and the floating ball 22 is not damaged.

Although not shown, the box 52 may be provided with a fixing means such as a work table. Further, the motor 54 may be a variable speed type or a constant speed rotating type. A means such as a transmission may be added to the motor.

[0014]

[Effect of device]

 As described above, according to the float ball tightening machine of the present invention, the float ball can be assembled to the lever very easily, and the labor saving can be significantly achieved. In addition, the assembly work efficiency of the ball tap is greatly improved.
