Description

TECHNICAL FIELD

[0001] The utility model relates to mechanical manufacturing technical field especially relates to a double -control drive arrangement for steel plate nut dismounting machine. BACKGROUND

[0002] The existing steel plate nut dismounting machine generally adopts single reverse switch control motor reverse rotation to realize nut dismounting. However, this method has the following defects:

[0003] 1. Operation delay: the operator needs to manually switch the reverse switch direction, the reaction speed is limited, and the machine is easy to spin out;

[0004] 2. Safety hazard: unable to quickly cut off the power supply in an emergency, increasing the risk of equipment out of control;

[0005] 3. Low efficiency: unable to achieve instantaneous multiple impact operation, affecting the locking or loosening effect, aiming at the above problems, the utility model file puts forward a double -control drive arrangement for steel plate nut dismounting machine. INVENTION CONTENTS

[0006] The utility model provides a double -control drive arrangement for steel plate nut dismounting machine, through the collaborative control of reverse switch and automatic reset switch, solves the problem of low efficiency, poor safety caused by single switch control.

[0007] The utility model provides the following technical scheme:

[0008] A double -control drive arrangement for steel plate nut dismounting machine, comprising:

[0009] Automatic reset switch and reverse switch, both are in series in mains circuit;

[0010] By operating the automatic reset switch, the circuit is turned on or turned off instantaneously;

[0011] Reverse switch, through motor input cable bundle connection steel plate nut dismounting machine motor, is used to control motor forward rotation, reverse rotation;

[0012] The automatic reset switch and reverse switch form a logical cooperation relationship, realize the independent control of whole machine power on-off and motor direction.

[0013] Preferably, the trigger mode of the automatic reset switch is one or a combination of pressure trigger, button trigger and foot pedal trigger.

[0014] Preferably, the reverse switch is single-speed control type or adjustable speed control type.

[0015] Preferably, the automatic reset switch controls one live wire or live wire and zero line in a single-phase power supply system, and controls two or three live wires in a three-phase power supply system.

[0016] Preferably, the automatic reset switch has a transient on-off function, supporting multiple impact operations.

[0017] Preferably, the double-control driving device is adapted to different specifications of steel plate nut disassembling machines.

[0018] Preferably, an electrical isolation module is arranged between the automatic reset switch and the forward-reverse switch, and the electrical isolation module includes an optical coupling isolator or a relay, used to block the electrical circuit of the forward-reverse switch control signal when the automatic reset switch is turned off, so as to ensure that the steel plate nut disassembling machine motor cannot receive a steering instruction in a power-off state.

[0019] The core is the cooperation and control architecture of the forward-reverse switch and the automatic reset switch. The function of the forward-reverse switch is precisely defined as controlling the steering of the motor, and its types include but are not limited to single-speed forward-reverse switches and adjustable-speed forward-reverse switches, which provide the possibility for diversified control of motor steering. The operating personnel controls the power-on link of the entire machine by operating the automatic reset switch, and the automatic reset switch is various, including pressure type, button type, pull knob type and foot pedal type, which can fully meet the needs of different use scenarios and operating personnel habits.

[0020] In terms of circuit connection, the adaptability of different power types is fully considered. For single-phase power steel plate nut disassembling machines, the automatic reset switch only needs to control one live wire, or one live wire plus one neutral wire, so as to realize effective management of the whole machine power-on; for three-phase power steel plate nut disassembling machines, the automatic reset switch can flexibly control two or three live wires according to actual conditions, and the remaining live wires (if any), ground wires (if any) and neutral wires (if any) follow the original connection method and remain unchanged, or are directly connected inside the automatic reset switch, ensuring the compatibility and stability of the design in different power environments.

[0021] Through this double-control driving design, the motor forward and reverse control and the whole machine power-on operation are successfully separated. In the moment of nut locking or loosening, the operating personnel can quickly release or close the automatic reset switch button, which not only makes the multiple impact locking and loosening of the nut more convenient and efficient, significantly improves the work efficiency, but also fundamentally eliminates the whole machine tail phenomenon caused by failure to turn off in time, greatly enhances the safety and reliability of the equipment in use, and provides a new and effective solution for the driving control of the steel plate nut disassembling machine.

[0022] It should be understood that the above general description and the following detailed description are only exemplary and cannot limit the utility model.

[0023] The beneficial effects are: 1. Safety is improved: by separating the power supply from the steering control, the operator can quickly cut off the power supply to avoid the tail phenomenon;

[0024] 2. Operation efficiency is optimized: support instantaneous multiple impact operation, improve locking or unscrewing efficiency;

[0025] 3. Strong compatibility: adapt to single-phase and three-phase power supply systems, and match various specifications of disassembly machines. BRIEF DESCRIPTION OF DRAWINGS
