Abstract
The utility model discloses an electromagnetic control clamping device. The clamping device comprises a first electromagnetic coil and a second electromagnetic coil. One end of the first electromagnetic coil is connected with a first wire and the other end of the first electromagnetic coil is grounded. The grounded end of the first electromagnetic coil is hinged to one end of a drive rod and one end of the second electromagnetic coil is connected with a second wire. The second wire and the first wire are connected to a power source in parallel. The power source is an alternating-current power source. The other end of the second electromagnetic coil is grounded. The grounded end of the second electromagnetic coil is hinged to the middle of the drive rod. The first electromagnetic coil and the second electromagnetic coil are located on the two sides of the drive rod respectively. The other end of the drive rod is connected with one end of a connection rod and the other end of the connection rod is hinged to one end of an L-shaped driven rod. The corner of the L-shaped driven rod is hinged and the other end of the L-shaped driven rod is connected with a pressing board. A workpiece can be automatically clamped or loosened through control over the current direction of the power source and the shortage that due to the fact that a reset spring is prone to damage, normal operation of the device is influenced is overcome.
Description
Technical field
The utility model relates to jig technology, is specifically related to a kind of Electromagnetic Control clamping device.
Background technology
clamping device is widely used in the processing of machine tool element, and in the production and processing of small batch workpiece, General Requirements clamping device is simple in structure, convenient operation.At present, existing clamping device generally adopts back-moving spring to reset, and due to the yielding damage of spring, therefore, need to change frequently spring to guarantee the normal work of clamping device, very inconvenient.
Utility model content
The utility model provides a kind of Electromagnetic Control clamping device, the problem using to solve the fragile impact of existing clamping device resetting structure.
Electromagnetic Control clamping device, comprise the first solenoid and the second solenoid, first solenoid one end is connected with the first wire, the first solenoid other end ground connection, one end of the earth terminal of the first solenoid and a drive rod is hinged, second solenoid one end is connected with the second wire, the second wire and the first wire are connected in parallel on power supply, described power supply is AC power, the second solenoid other end ground connection, the earth terminal of the second solenoid and the middle part of drive rod are hinged, the first solenoid and the second solenoid are positioned at the both sides of drive rod, the other end of drive rod is connected with connecting rod one end, the other end of connecting rod and L shaped follower lever one end are hinged, the corner of L shaped follower lever is hinged, the other end of L shaped follower lever is connected with pressing plate.
The beneficial effects of the utility model: this installation's power source is AC power, in the time that positive electricity is provided, the first solenoid upper end is the N utmost point, lower end is the S utmost point, the second solenoid upper end is the N utmost point, lower end is the S utmost point, like this between the second solenoid and the first solenoid, exist one by the second solenoid N utmost point to the magneticaction between the first solenoid S utmost point, under the effect of this power, the end that drive rod is connected with connecting rod will upwards swing, connecting rod moves upward, the one end that drives follower lever to be connected with pressing plate upwards swings, thereby make pressing plate away from workpiece, automatically unclamp workpiece, otherwise, in the time of power supply opposite direction, clamping work pieces.This device just can be realized the Automatic-clamping of workpiece and be unclamped action by the control of source current direction, easy to operate, has avoided using the fragile drawback that affects the normal work of device of back-moving spring.
Further, pressing plate end is compressed part, and four angles of compressed part are equipped with fixture block.Fixture block has the effect of positioning workpieces, prevents from producing in piece-holder process small slip.
