Description
Technical Field
[0001] The utility model belongs to the technical field of slow-moving wire cutting machines, in particular to a slow-moving wire cutting fixture. Background Art
[0002] Wire cutting is a type of electric spark wire cutting. It uses a continuously moving thin metal wire as an electrode to perform pulse spark discharge to erode the metal and cut and shape the workpiece. During the cutting process, a clamp is required to clamp the workpiece.
[0003] When using the existing slow-feed wire cutting fixture, the workpiece is usually placed tightly against a fixed plate on one side, and then a screw is used to drive the clamping plate to move to the other side of the workpiece. The workpiece is clamped and fixed before cutting. During long-term use and observation, it is found that the existing slow-feed wire cutting fixture usually uses a fixed plate and a movable clamping plate to clamp and fix the workpiece. The fixed plate is usually close to the end of the fixture, which makes it difficult to align the center of the workpiece with the center of the cutting machine after it is clamped and fixed, thereby affecting the cutting deviation.
[0004] To this end, the utility model provides a slow-wire cutting fixture. Utility Model Content

At this time, the slider 15 and the fixed plate 14 move the same distance at the same time to clamp the workpiece in the center of the fixed table 17. In this step, the fixed table 17 is connected to the laser lamp 18 by setting the fixed table 17 to align the center of the cutting machine. At the same time, the bidirectional threaded rod 12 drives the fixed plate 14 to move the same distance to the fixed table 17, so that the workpiece can be clamped in the center of the fixed table 17 to reduce the misalignment between the workpiece and the center of the cutting machine, which leads to deviations during cutting.
[0025] like Figure 2 As shown, a plurality of slide grooves 2 are opened in the middle of the fixed plate 14; a plurality of slide rods 21 are slidably connected to the middle of the fixed plate 14; the slide rods 21 slidably cooperate with the slide grooves 2; during operation, when the fixed plate 14 clamps and fixes the workpiece, the end of the slide rod 21 will contact the surface of the workpiece. When the shape of the workpiece is irregular, the slide rod 21 will produce different degrees of stretching and contact the irregular surface of the workpiece. In this step, by setting the fixed plate 14 to connect multiple slide rods 21, workpieces of different shapes can be clamped. When the surface of the workpiece is irregular, the slide rods 21 will respectively produce different degrees of contraction and generate rebound force to clamp and fix the workpiece, so as to improve the applicability of clamping and fixing.
[0026] like Figure 2 As shown, a suction cup 3 is fixedly connected to the end of the slide bar 21; the suction cup 3 is arranged toward the fixed platform 17; during operation, when the end of the slide bar 21 contacts the surface of the workpiece, the suction cup 3 will be adsorbed on the surface of the workpiece to improve the tightness of the connection between the slide bar 21 and the workpiece. In this step, the suction cup 3 is arranged to connect the slide bar 21, which can be adsorbed on the surface of the workpiece when the slide bar 21 clamps and fixes the workpiece, so as to improve the tightness of the connection between the slide bar 21 and the workpiece, so as to improve the clamping effect of the slide bar 21 on the workpiece.
[0027] like Figure 3 As shown, a collecting box 4 is fixedly connected to the bottom of the base plate 1; a drawer box 41 is placed on the inner wall of the collecting box 4; the collecting box 4 and the drawer box 41 are in sliding cooperation; during operation, the debris generated when the workpiece is cut will fall, and when the debris falls from the bottom of the base plate 1 to the drawer box 41 below, the drawer box 41 will collect the debris. After the collection is completed, the drawer box 41 is pulled out of the collecting box 4 to take out the debris, and then the drawer box 41 is reset to the collecting box 4. In this step, by setting the collecting box 4 and the drawer box 41, the debris generated during cutting can be collected to reduce the accumulation and pollution caused by the scattering of debris. At the same time, the drawing and returning settings of the drawer box 41 can improve the convenience of taking out more collected debris.
[0028] like Figure 3 As shown, the inner wall of the collection box 4 is provided with a filter plate 5; the filter plate 5 is detachably installed; during operation, when the debris enters the draw box 41, it will pass through the filter plate 5. At this time, the filter plate 5 can filter the larger debris, and the smaller debris will continue to fall into the draw box 41 below to be collected. When the collection is completed, the filter plate 5 is removed to clean the debris and then install it again. In this step, the filter plate 5 can be set to filter the debris entering the draw box 41, and the larger debris can be filtered out, so as to reduce the accumulation of larger debris entering the draw box 41, and at the same time, the convenience of classifying and recycling some metal debris can be improved.

In this step, the ball bearings 6 are arranged to rotate when the slider 15 moves, so as to reduce the friction between the slider 15 and the slide rail 16, thereby making the slider 15 easier to slide and improving the stability of the slider 15 when sliding.
[0030] like Figure 4 As shown, the side wall of the handle 13 is provided with a rubber sleeve 7; during operation, when the handle 13 is held and rotated, it will contact the rubber sleeve 7, and at this time, the rubber sleeve 7 can increase the friction force on the surface of the handle 13. In this step, the friction force when the handle 13 is rotated can be increased by setting the rubber sleeve 7, thereby reducing the occurrence of slipping.

When the collection is completed, the drawer box 41 is pulled out of the collection box 4 to take out the debris, and then the drawer box 41 is reset to the collection box 4, when the debris enters the drawer box 41, it will pass through the filter plate 5, at this time the filter plate 5 can filter the larger debris, the smaller debris will continue to fall into the drawer box 41 below and be collected, when the collection is completed, the filter plate 5 will be removed to clean the debris and then install and reset, when the bidirectional threaded rod 12 drives the slider 15 to slide in the slide rail 16, the slider 15 will contact the ball 6 on the side wall of the slide rail 16, when the slider 15 moves, it can drive the ball 6 to rotate, when the rotating handle 13 is held, it will contact the rubber sleeve 7, at this time the rubber sleeve 7 can increase the friction of the handle 13 surface.
