Two-way electromagnetic type bench vice

Abstract

The invention discloses a two-way electromagnetic type bench vice. The two-way electromagnetic type bench vice comprises a groove shell. A working groove range is arranged at the center of the upper surface of the groove shell, a main hollow shell body is arranged at the center, in the working groove range, of the groove shell, wherein the groove shell and the main hollow shell body are of an integrated structure, a 51single chip microcomputer is installed at the top of the main hollow shell body, an iron core with the side face being sleeved with a coil is installed at the center of the interior of the main hollow shell body, and the control input end of the coil is connected with the control output end of the 51single chip microcomputer through a wire. According to the two-way electromagnetic type bench vice, an electromagnetic type strength resisting effect can be conducted on a threaded rod used for fastening, so that stress magnitude of a threaded tooth structure in the fasteningprocess is reduced, and the service life of the two-way electromagnetic type bench vice is prolonged; and in addition, the two-way electromagnetic type bench vice is provided with an anti-overloadingprotective mechanism, the phenomenon that a thread is damaged due to the fact that the twisting strength is overlarge can be effectively prevented, moreover, the two-way electromagnetic type bench vice can simultaneously fix two sets of parts, the utilization rate is high, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a two-way electromagnetic bench vise. Background technique [0002] At present, China's patent number CN201310720936.7 has announced a bench vise, including a frame, a main clamp, a main screw and a rotating handle. Connect the rotating handle, set a sub-clamp on both sides of the clamping force direction of the main clamp, extend the sub-screw from the sub-clamp and pass through the side of the opposite frame, and set a torque nut on the sub-screw outside the frame , when in use, firstly rotate the rotary handle to drive the main fixture to clamp the workpiece, then further clamp the workpiece, move the auxiliary fixtures on both sides of the main fixture to adjust its position, and finally rotate the torque nut to shrink the auxiliary screw, so as to obtain from the other two Clamp the workpiece at one point. Obviously, when the above-mentioned device is working, the main th...

[0002] At present, China's patent number CN201310720936.7 has announced a bench vise, including a frame, a main clamp, a main screw and a rotating handle. Connect the rotating handle, set a sub-clamp on both sides of the clamping force direction of the main clamp, extend the sub-screw from the sub-clamp and pass through the side of the opposite frame, and set a torque nut on the sub-screw outside the frame , when in use, firstly rotate the rotary handle to drive the main fixture to clamp the workpiece, then further clamp the workpiece, move the auxiliary fixtures on both sides of the main fixture to adjust its position, and finally rotate the torque nut to shrink the auxiliary screw, so as to obtain from the other two Clamp the workpiece at one point. Obviously, when the above-mentioned device is working, the main threaded rod first acts as a force bearing. After the main threaded rod receives the maximum pressure, the secondary threaded rod is used to bear the force. First, due to the main thread The first force on the rod leads to a large force, so the service life of its thread teeth is low, which can easily lead to deformation of the thread teeth. In the group of secondary threaded rods, there must be a problem of force first, and the force will cause the thread teeth to deform. In addition, because multiple groups of secondary threaded rods do not rotate at the same time, the pressure of each group of secondary threaded rods on the included angle will not Same, long time will lead to angle damage

[0003] In addition, the general bench vise is only one-way, and can only perform a single fastening function. When in use, the utilization rate is relatively low
