Description
Technical Field
[0001] The present application relates to the technical field of bench vises, and more specifically, to a bench vise device with a multi-directionally adjustable working angle. Background Art
[0002] A bench vise, also known as a vice or bench clamp, is a universal fixture used by fitters to fix workpieces. It is installed on the workbench to clamp the workpiece for processing. It is an essential tool in the fitter's workshop. The current bench vise is mainly composed of a clamp body, a fixed jaw, a movable jaw and a screw. When the handle is shaken to rotate the screw, the movable jaw can be driven to move relative to the fixed jaw to clamp or loosen.
[0003] The clamping range of movable jaws and fixed jaws is usually linear, that is, they can only clamp the workpiece along a straight line. Since they do not have the function of angle adjustment, this means that when it is necessary to clamp curved tools or workpieces (such as L-shaped profiles), the operator cannot adjust the jaws to the appropriate angle to adapt to the shape of the workpiece. This limitation may result in the workpiece not being effectively clamped, and may even cause damage to the jaws or deformation of the workpiece.
[0004] In view of this, we propose a bench vise device with multi-directional adjustable working angle. Summary of the Invention

Then, the limit screw 32 is rotated clockwise, and the limit screw 32 is stuck in the first annular groove 41. At this time, when the first lead screw 4 rotates, the first annular groove 41 drives the limit screw 32 and the movable jaw 3 to slide and adjust along the clamp body 1. After the limit screw 32 is rotated counterclockwise and disengaged from the first annular groove 41, the first lead screw 4 and the movable jaw 3 can be separated.

[0040] Working principle: When it is necessary to clamp a linear workpiece, rotate the clamp body 1 on one side, and make the two groups of clamp bodies 1 approach and fit together under the meshing action of the gear 13, then turn the locking screw 12 clockwise to fix the clamp body 1 on the arc plate 51, then turn the limit screw 32 counterclockwise and disengage from the first annular groove 41, turn the first lead screw 4 counterclockwise to move the first lead screw 4 to the left so as not to affect the sliding of the movable jaw 3, then slide the two groups of movable jaws 3 and press them against the second lead screw 6, and insert the U-shaped card 7 into the second annular groove 61, and at the same time, the two insertion rods 71 are respectively inserted into the corresponding insertion holes 33, and then rotating the second lead screw 6 can drive the two groups of movable jaws 3 to slide and adjust synchronously along the clamp body 1, and now the linear workpiece can be clamped on the bench vise;
[0041] When it is necessary to clamp the bent workpiece, loosen the locking screw 12, then remove the U-shaped clip 7 from the movable jaw 3, and rotate the second screw 6 counterclockwise to move it to the left, and then rotate the clamp body 1 on one side to rotate around the work-shaped axis 14. Under the action of the engagement of the two gears 13, the acute angle between the two sets of clamp bodies 1 gradually increases, and by observing the scale groove 513 degrees corresponding to the edge of the outer wall of the clamp body 1, and the same as the bending angle of the bent workpiece, rotate the locking screw 12 clockwise to fix the clamp body 1 on the arc plate 51, and then move the movable jaw 3 so that the first annular groove 41 end of the first screw 4 is inserted into the screw mounting opening 31 and abuts against the inner wall of the opening, rotate the limit screw 32 clockwise, and the limit screw 32 is stuck in the first annular groove 41, then place the workpiece between the movable jaw 3 and the fixed jaw 2, and rotate the two first screws 4 clockwise respectively to clamp the bent workpiece.
