detailed description

Referring to the accompanying drawings, the structure of a specific embodiment of the utility model includes a workbench 1, a fixture riveted on the workbench, two guide rails 2 erected on the workbench and parallel to each other, and a cutting tool slidingly installed on the guide rail 2. device; the fixture includes a strip-shaped base 3, the two ends of the base 3 protrude upwards to form two convex parts 4, and the inner side of each convex part 4 is equipped with a movable jaw 5, and the movable jaw 5 is formed by the base 3 The guide groove 6 guides and slides, and a screw hole is provided on the convex part 4, and a lead screw 7 is pierced in the screw hole, and the inner end of the lead screw 7 is connected to the outside of the movable jaw 5 by bearing rotation; the cutting device includes a beam frame 9, The cutter connecting rod 10 vertically pierced on the beam frame 9, the cutting tool 11 fixed on the lower end of the cutter connecting rod 10 and the motor 12 for driving the cutting tool 11 to rotate, the two ends of the beam frame 9 are slidably sleeved on the two sides. On the bar guide rail 2, an operating handle 13 is arranged on the side of the tool connecting rod 10, and a chute 14 is hollowed out on the beam frame 9, and two parallel and corresponding up and down blocks 15 are affixed on the tool connecting rod 10, and the two blocks 15 are respectively Sliding contact with the upper surface and the lower surface of the crossbeam frame 9, the positioning bolt 16 is vertically installed on the block 15;

The beam frame 9 is provided with a scale 17, the block 15 is provided with a positioning pin 18, and the cutter connecting rod 10 is provided with a laser lamp 19 through a longitudinal wheel, and the positioning pin 17, the laser lamp 19 and the cutting tool 11 are located at on the same vertical plane.

Bosses 8 are arranged on the lower part of the inner side of the movable jaw 5 . The boss 8 can hold the bottom of the test piece, so that the bottom of the test piece is higher than the upper surface of the base 3, which helps to realize the through cutting.

The working principle of the utility model is: generally speaking, the clamp is used to clamp the test piece, the cutting device is used to locate the cutting position and complete the cutting, and the guide rail 2 is used to guide the cutting device to cut along a straight line. The cutting process is described in detail below.

First clamp the test piece: the two movable jaws 5 are driven to slide along the guide groove 6 through the cooperation of the lead screw 7 and the convex part 4, and the two movable jaws 5 clamp the test piece. The base 3 has a longer length, so that The two movable jaws 5 have a relatively large sliding distance, so the two movable jaws 5 can not only clamp the short side of the test piece, but also make the long side of the test piece face the cutting tool 11, thereby completing the process in a long time. The side is the cutting task of the incision, and the long side of the test piece can be clamped so that the short side of the test piece is facing the cutting tool 11, thereby completing the cutting task with the short side of the test piece as the incision.

Then locate the cutting position: after clamping the test piece, turn on the laser light 19, turn the vertical wheel, adjust the pitch angle of the beam of the laser light 19, and slide the tool connecting rod 10 in the chute 14 to make the laser light 19 Position the light beam to the edge position of the test piece, record the initial scale value indicated by the positioning pin 18, then slide the tool connecting rod 10 and observe the position of the positioning pin 18 synchronously, when the difference between the scale indicated by the positioning pin 18 and the initial scale value is equal to the required When cutting a thin thickness value, tighten the positioning bolt 16, and the cutting position positioning is completed. Of course, it is also possible to draw the cutting device closer to the test piece without turning on the laser light 19, and use the cutting tool 11 to directly locate the cutting position. Wherein, the locking block 15 can not only cooperate with the positioning bolt 16 to lock the tool connecting rod 10, but also prevent the tool connecting rod 10 from falling or shaking.

Finally, the cutting is completed: the motor 12 is started to drive the cutting tool 11 to run, and the operating handle 13 is pulled to make the cutting device move along the guide rail 2 for cutting.

The utility model can not only adjust the position of the cutting tool 11, but also can adjust the position of the two movable jaws 5 clamping the test piece, and cooperate with the longer base 3 to make the positioning of the cutting position more flexible.

The above description is only proposed as an implementable technical solution of the utility model, not as a single restriction on the technical solution itself.
