Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the following description, together with the accompanying drawings and the embodiments of the present invention, will be made to clearly describe the technical solutions in the embodiments of the present invention, and obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1 and 4, the tool positioning fixture comprises a bottom plate 1, wherein the bottom plate 1 is made of a stainless steel plate to prevent rusting. The two ends of the bottom plate 1 are both fixed with side frames 2, and the side frames 2 are provided with threaded holes 13 and at least two through holes 8. The through holes 8 are located on both sides of the threaded hole 13. The threaded hole 13 is embedded with the main screw rod 6, the main screw rod 6 is provided with external threads outside, and the external threads are matched with the internal threads inside the threaded hole 13. One end of the main screw 6 is connected to a sliding clamping block 3, preferably hinged. And a hand crank 7 is arranged at one end of the main screw rod 6 far away from the sliding clamping block 3. The accessible rotates crank 7 and drives the leading screw 6 and rotate to screw thread through the screw hole 13 in with leading screw 6 forward propulsion, thereby promote slip clamp splice 3 to the work piece removal.

As shown in fig. 1, 2 and 3, two sliding grooves 12 are arranged on the upper side of the bottom plate 1, a sliding rail 4 is installed inside each sliding groove 12, the bottom of the sliding clamping block 3 is connected with the sliding rail 4 in a sliding manner through a sliding block, and the sliding clamping block 3 can move more smoothly through the sliding rail 4. The slide rail 4 is perpendicular to the slide clamping block 3. The inside embedding of through-hole 8 has fine setting screw rod 5, and fine setting screw rod 5 passes the inside of slip clamp splice 3, and fine setting screw rod 5 passes through threaded connection with slip clamp splice 3. And one end of the fine adjustment screw 5, which is far away from the sanding block 9, is provided with a fine adjustment crank. The inner diameter of the through hole 8 is larger than the inner diameter of the section of the fine adjustment screw 5, so that the fine adjustment screw 5 can freely shuttle in the through hole 8. When the sliding clamping block 3 moves, the fine adjustment screw 5 moves along with the sliding clamping block 3 because the fine adjustment screw 5 is connected with the sliding clamping block 3 through threads. The end of the fine adjustment screw rod 5 is hinged with a fine adjustment rotating block 10, the fine adjustment rotating block 10 is connected with the end of the fine adjustment screw rod 5 through a spring 11, and a sanding block 9 is installed on the fine adjustment rotating block 10. When the fine tuning rotating block 10 is in contact with a workpiece, the fine tuning rotating block can automatically rotate to a proper angle according to the angle of a contact surface, and the supporting function of the spring 11 assists the fine tuning rotating block 10 to rotate. The sanding block 9 has a higher coefficient of friction and fixes the workpiece more firmly by increasing the friction with the contact surface.

When using this frock clamp, can rotate crank 7 earlier and drive the lead screw 6 and rotate, thereby advance lead screw 6 through the internal thread in the screw hole 13, thereby promote slip clamp splice 3 and remove to the work piece direction, when slip clamp splice 3 removes, because fine setting screw 5 passes through threaded connection with slip clamp splice 3, consequently fine setting screw 5 can remove thereupon, when the position that is close to the work piece is removed to sanding block 9, can adjust fine setting screw 5 according to the shape of work piece, the fine setting screw 5 through the work piece both sides presss from both sides the work piece tightly, the work piece has just been firmly fixed a position and has pressed from both sides tightly after each sanding block 9 all pushes up tightly. The tool positioning clamp has good clamping effect and is applicable to various workpiece shapes.
