Abstract
The invention discloses an automatically clamped adjustable spanner. The spanner can be clamped or loosened automatically. The adjustable spanner comprises a handle, a fixed jaw and a movable jaw, wherein a spur rack arranged on the movable jaw is meshed with a worm. The adjustable spanner is characterized in that: the worm is connected with an output shaft of a direct current motor; a contact switch is arranged in the movable jaw; a motor forward switch and a motor reverse switch are respectively arranged at the joints of the handle and the jaws; the contact switch, the motor forward switch and the motor reverse switch are electrically connected to a controller; and the controller is electrically connected with the motor. Time for matching the jaws with nuts is reduced; and during use, the worm is not screwed by fingers any more, so time is saved, the adjustable spanner is convenient to use, and work efficiency is improved.
Description
Technical field
The present invention relates to a kind of monkey wrench, the monkey wrench of a kind of automatic clamping specifically.
Background technology
The inconvenience that brings when remedying nutting, reduce the time that jaw matches with nut, many times the master worker will be with pointing the fast rotational worm screw, busy work often makes the master worker dog-tired, even rotation sometimes too fast and make jaw very little, improper, rotation again again.
Summary of the invention
At above-mentioned deficiency, the invention provides a kind of monkey wrench of automatic clamping, easy for installation when using, adjust rapidly.
The present invention is achieved by the following technical solutions: a kind of monkey wrench of automatic clamping, comprise handle, regular jaw and moving jaw, spur rack that moving jaw is provided with and worm engaging, it is characterized in that, described worm screw links to each other with the output shaft of direct current generator, be provided with contact-making switch in moving jaw, motor positive turn-off pass and motor reversal switch are arranged at the joint portion of handle and jaw respectively; Described contact-making switch, motor positive turn-off pass and motor reversal switch all are electrically connected controller, and described controller is electrically connected motor.
The invention has the beneficial effects as follows: reduce the time that jaw matches with nut, no longer twist worm screw with finger during use, saved the time, the convenient use improved operating efficiency.
Description of drawings
Fig. 1 is a stereogram of the present invention;
Among Fig. 1: 1 handle, the positive turn-off of 2 motors closes 3 motor reversal switches, 4 spanner retained parts, 5 direct current generators, 6 power supplys, 7 worm screws, 8 spur racks, 9 contact-making switches.
Specific embodiment
As Fig. 1, a kind of monkey wrench of automatic clamping comprises handle 1 and spanner retained part, and described spanner retained part comprises regular jaw and moving jaw, and moving jaw is provided with spur rack 8, this spur rack 8 and worm screw 7 engagements.
Worm screw 7 links to each other with the output shaft of direct current generator 5, and drive worm screw 7 by direct current generator 5 and rotate, through the displacement of spur rack 8 and then realization moving jaw, clamping or unclamping by moving jaw and regular jaw in conjunction with realizing.Motor positive turn-off pass 2 and motor reversal switch 3 are arranged at the joint portion of handle 1 and jaw respectively, and the positive turn-off of motor closes and the motor reversal switch all is electrically connected controller, and described controller is electrically connected direct current generator 5.Direct current generator 5 provides electric power by power supply 6.
The positive turn-off of motor closes 2 to be connected, and can make moving jaw and regular jaw realize clamping, and is provided with contact-making switch 9 in moving jaw, and contact-making switch 9 is electrically connected controller.When moving jaw touches clamped workpiece in clamping process, contact-making switch 9 actions, direct current generator 5 quits work, and clamping is finished.
During use, earlier jaw is opened by motor reversal switch 3, then, hold handle 1 alignment pieces of spanner, pin the positive turn-off of motor pass 2 with thumb direct current generator 5 is just being changeed, jaw of spanner is reduced, and make moving jaw gradually near workpiece, and when moving jaw touches workpiece in clamping process, contact-making switch 9 actions, direct current generator 5 quits work, and clamping is finished.Rotate by handle and tighten or loosen workpiece this moment, then, by motor reversal switch 3 jaw opened again, takes down spanner.Whole operation is finished.
Claims (1)
