TECHNICAL FIELD
[0001] The utility model relates to sheet metal polishing fixed technical field especially relates to a sheet metal polishing workstation workpiece fixed antiskid device. BACKGROUND
[0002] Sheet metal parts need to be fixed through a limiting device during polishing processing to prevent the workpiece from sliding or deviating under the action of a high-speed rotating polishing tool (such as an angle grinder or a grinding machine). Traditional fixing techniques mainly rely on a vacuum suction device, which is adsorbed to the surface of the workpiece through an array of suction cups or a vacuum cavity and is fixed using atmospheric pressure differences. However, as the processing requirements are upgraded to complex curved surfaces and multi-angle processing directions, the limitations of existing suction-type fixing devices are increasingly apparent.
[0003] When the polishing tool is at a non-perpendicular angle (such as 30°~60°) to the surface of the workpiece, the shear force borne by the suction device significantly increases (experiments show that the shear force at an inclination of 45° is 1.4 times that of the vertical direction), resulting in a decrease in suction force and poor stability of the workpiece, which can easily cause the workpiece to slide during polishing, affecting the polishing accuracy. To address this issue, we propose a sheet metal polishing workstation workpiece fixed antiskid device. SUMMARY

[0023] Further, referring to Figure 2 and Figure 3 It can be known that the upper and lower ends of the movable rods 24 are symmetrically and fixedly provided with limiting frames 25, the diameter of the limiting frames 25 is larger than the diameter of the rectangular grooves, and the limiting frames 25 are connected to the rectangular grooves in a buckle type, so that the limiting can be realized by the limiting frames 25 in the process of use.
[0024] Further, referring to Figure 2 and Figure 3 It can be known that the top end center surface of the guide plate 21 is provided with a rectangular groove, limiting blocks 5 are symmetrically and fixedly installed in the rectangular groove, the limiting blocks 5 are provided in two groups, the two groups of limiting blocks 5 form a V-shaped sliding groove, the structural feature of the V-shaped groove is a symmetrical inclined surface, which can be automatically centered, improve the positioning accuracy, reduce the adjustment time, and secondly, the self-adaptive clamping capacity of the V-shaped groove can adapt to workpieces of different diameters, and increase the versatility of the equipment.
[0025] Further, referring to Figure 3 and Figure 4It can be seen that rectangular guide rods 4 are symmetrically fixedly installed on both sides of the rectangular groove at the top of the guide plate 21, and a slide rail is opened horizontally inside the rectangular guide rod 4. A slider 10 is inserted inside the slide rail, and the slider 10 is fixedly connected to the baffle 6 through the connecting column. The bottom end of the baffle 6 is adapted to the V-shaped groove formed by the limiting block 5. During use, the slider 10 can limit the movement of the baffle 6 and keep the baffle 6 moving in a straight line.
[0026] Furthermore, refer to Figure 4 It can be seen that the top of the rectangular guide rod 4 is provided with a sliding groove, and the sliding groove is connected to the slide rail. A second limiting rod 11 is inserted inside the sliding groove, and a first limiting rod 3 is inserted inside the second limiting rod 11. During use, the second limiting rod 11 plays a limiting role on the slider 10 to prevent the slider 10 from falling off.
[0027] Furthermore, referring to 5, it can be seen that the top center surface of the baffle 6 is connected to a threaded rod 7 via a bearing, and a threaded sleeve 8 is fitted on the surface of the threaded rod 7.
