Description

Technical Field

[0001] The utility model relates to the technical field of travel switches, in particular to a micro-rotary switch. Background Art

[0002] The processing and manufacturing process of new energy wire harnesses mainly includes wire cutting, crimping, subpackaging, assembly, testing and other processes. Among them, the blanks that have not been processed first need to be cut. During the wire cutting process, the cables need to be straightened and released. Currently, most equipment uses the method of loading counterweights for straightening.

[0003] Specifically, during the routing process, the wire is pressed down by the wire storage wheel, and the wire storage wheel needs to be installed at the end of the rod. When the wire is routed too fast, the wire storage wheel will not move down in time, causing the rod to rise. When the wire is routed too slowly, it will cause the rod to sink. When the swing amplitude of the rod is too large, it will cause the wire harness to be unevenly straightened, which will lead to problems with the wire harness being unqualified.

[0004] In view of this, in order to avoid such problems, the applicant proposed a new technical solution, namely, installing a micro-rotary switch on the rod. When the rod swings significantly, the device can be immediately shut down to prevent the problem of uneven straightening of the storage wheel. Utility Model Content

[0005] To this end, the utility model provides a micro-rotary switch to solve the problem in the prior art that the storage wheel is not evenly straightened due to the excessive swing amplitude of the rod.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] The utility model discloses a micro rotary switch, comprising:

[0008] The installation base has a rotating shaft inserted through the center thereof, a bearing is sleeved at the tail of the rotating shaft, and the bearing is installed at the tail of the installation base;

[0009] A micro switch, arranged on the side of the mounting base;

[0010] An adjustable dial is sleeved on the rotating shaft and is coaxially connected to the rotating shaft;

[0011] Wherein, two paddles are arranged on the circumference of the outer edge of the adjustable dial, and both of the paddles are suitable for abutting against the contacts of the micro switch.

[0012] Furthermore, the plectrum includes:

[0013] A connecting piece, the tail of which is provided with a hinge hole, and the connecting piece is hingedly arranged on the adjustable dial through the hinge hole;

[0014] A circular slot, the center of which coincides with the hinge hole, and the circular slot is fixed to the adjustable dial by bolts;

[0015] A pressing plate is arranged at the head of the connecting piece and is suitable for abutting against the contact of the micro switch to close the micro switch.

[0016] Furthermore, the mounting base includes:

[0017] The mounting block has an adjustment seat on the side, and a micro switch is movably arranged on the adjustment seat;

[0018] The bracket is slidably sleeved on the rotating shaft, and the bracket is arranged at the front end of the mounting block.

[0019] Furthermore, the mounting base and the rotating shaft are both made of metal.

[0020] Furthermore, an angle sensor is provided at the head end of the rotating shaft.

[0021] Furthermore, the micro switch is connected to a contactor.

[0022] The utility model has the following advantages:

[0023] The micro-rotary switch disclosed in the utility model is installed on the wire harness straightening device. The micro-switch is triggered by a paddle installed on an adjustable dial to cut off the power supply. When the wiring speed of the device is too fast, the wire storage wheel cannot completely straighten the wire harness, which directly causes the wire storage wheel to drive the rod to deflect. At this time, through the micro-rotary switch, when the swing angle of the wire storage wheel exceeds the set range, the rod drives the rotating shaft to rotate, which can trigger the micro-switch, thereby cutting off the power supply of the device and interrupting the process of straightening the wire harness. Compared with the existing technology, the utility model has a simple structure, flexible use, and is easy to install, and solves the problem of uneven straightening of the wire storage wheel due to excessive swing amplitude of the rod.
