Problems solved by technology

Such a design is costly. When two power sources are used, the utilization rate is often not high, and the structural size is large. When the two motions are required to work in relation to each other, sensors and signal processing systems need to be added to control the two execution motions respectively. In order, so that the reaction speed is relatively slow

Embodiment 1

[0041] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the aforesaid three-terminal input / output mechanism is used as a torque comparator for an automatic cable tie tool, the internal and external gears 2 drive the cable tie tensioning wheel 30 through a tensioning gear 31, and the planetary wheel base 5. Drive the cutter 8 through the dial pin 6 fixed on the planetary wheel base 5; the planetary wheel base motion control device 70 is used to adjust the tightening force of the object to be bound, twist the adjusting screw 71, and the vernier 73 moves along the axial direction of the adjustment screw 71, the vernier 73 compresses or releases the adjustment spring 72, the elastic force of the adjustment spring 72 acts on the slider 74, and the slider 74 then moves the adjustment spring 72 The elastic force acts on the fork-shaped structure above the planetary wheel base 5 and makes the fork-shaped structure above the planetary wheel base 5 lock the planetary whe...

Embodiment 2

[0045] Such as Figure 5 , Image 6 As shown, the aforesaid three-terminal input / output mechanism is used as a torque comparator for an automatic cable tie tool, the external power is input from the sun gear 1, and the sun gear 1 is pressed figure 2 Rotate in the direction of 50 as shown, the internal and external gear 2 drives the cable tie tensioning wheel 30 through the tensioning gear 31, the planetary wheel base motion control device 70 is used to adjust the tightening force of the object to be bound, and the slider 74 is Under the action of the elastic force of the adjustment spring 72, the rising edge of the planetary wheel base 5 whose shape is a cam profile contacts and locks the planetary wheel base 5; when the sun gear 1 rotates, the motion of the planetary wheel base is controlled The slider 74 of the device 70 locks the planetary wheel base 5, and the inner and outer gears 2 drive the strap tensioning wheel 30 through the tightening gear 31. When the strap tight...

Embodiment 3

[0049] Such as Figure 9 , Figure 10 Shown: Utilizing the above-mentioned three-terminal input / output mechanism that can convert the torque borne by the internal and external gears 2 to the change of the rotational position of the planetary wheel base 5, a sensor 9 is added to detect the planetary wheel base 5 Whether to act to determine whether the binding action of the automatic cable tie tool is successful; the working principle is: the external power drives the sun gear 1 to press figure 2 Rotate in the direction of 50 as shown, the internal and external gear 2 drives the tensioning wheel 30 through the tensioning gear 31, the planetary wheel base motion control device 70 sets the tensioning force of the cable tie, and the planetary wheel base 5 passes through the dial pin 6 Drive the cutter 8 to cut off the cable tie; if there is a cable tie to enter the tension wheel 30 of the automatic cable tie tool, and when the cable tie tension reaches the set value of the planet...

Abstract

The invention provides a three-end input / output mechanism which comprises a sun gear, an internal-external gear, planet gears, a planet wheel axle, a planet wheel base and a planet wheel base motion control device, wherein the internal-external gear and the planet wheel base are adjacent and are coaxially mounted with the sun gear; the planet wheel axle is fixed on the planet wheel base; the planet gear sleeves the planet wheel axle; the number of the planet gears is 2, 3, 4, 5 or 6; the planet gears are meshed with an annular gear of the internal-external gear and the sun gear at the same time; the sun gear, the internal-external gear and the planet wheel base form three input / output ends; the planet wheel base motion control device is used for setting a motion threshold of the motion of the planet wheel base. The three-end input / output mechanism provided by the invention is applied to the linkage and detection of the tensioning and cutting of an automatic cable tying tool and to twice or more tensioning, and also can realize 'inert forwarding and positive retreating' of the output action.

Description

technical field [0001] The invention relates to a movement mechanism, in particular to a three-terminal input / output mechanism. Background technique [0002] Traditionally, when one motor or one other power source is used and two actions are required, the general design is to convert one input motion into two output branches through gears, cams or linkages, and the two branches simultaneously To move synchronously according to the designed periodic law, to stop one execution action, two execution actions must be stopped at the same time; these two execution actions are actually "rigid" associated. [0003] In order to make the above two execution actions have a certain degree of independence or called "flexibility", the common design will use two motors or two other power sources to drive the two execution actions respectively. Such a design is costly. When two power sources are used, the utilization rate is often not high, and the structural size is large. When the two mot...
