Description

Technical Field

[0001] This utility model relates to the field of machine tool equipment technology, and in particular to an improved vertical spindle slide rail mechanism for a grinding machine. Background Technology

[0002] A grinding machine is a machine tool that uses abrasive wheels to grind the surface of a workpiece. Most grinding machines use high-speed rotating grinding wheels for grinding, while a few use other abrasive wheels and free abrasives, such as honing machines, ultra-precision machining tools, belt grinders, lapping machines, and polishing machines. Grinding machines can process materials with high hardness, such as hardened steel and cemented carbide; they can also process brittle materials, such as glass and granite. Grinding machines can perform high-precision grinding with very low surface roughness, as well as high-efficiency grinding, such as heavy-duty grinding.

[0003] Existing grinding machines generally do not have high precision control over the spindle. Before applying abrasive to the surface of a product, engineers must first adjust the precision of the worktable to control the grinding allowance. The grinding allowance needs to be adjusted for each part processed. When the cutting amount of the workpiece is sufficient, the operator needs to separate the grinding wheel from the workpiece as soon as possible to avoid excessive wear of the workpiece by the grinding wheel. The grinding wheel cannot separate from the workpiece on its own after grinding, which is quite troublesome. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1 to 5 This utility model provides an improved vertical spindle slide rail mechanism for a grinding machine, comprising a machining table 1, a protective cover 2 on the top surface of the machining table 1, an electromagnetic block 4 on the top surface of the protective cover 2, a vertically fixed column 5 on the rear side of the machining table 1, a U-shaped block 8 connected to the front side of the column 5, a connecting block 13 telescopically connected to the front side of the U-shaped block 8, a through groove 16 on the front side of the connecting block 13, a guide block 20 vertically telescopically connected within the through groove 16, a through hole 27 vertically fixed on the top surface of the guide block 20, and a guide rod 2 axially slidingly passing through the through hole 27. 1. The guide rod 21 is vertically fixed in the through groove 2 16. The outer edge of the guide rod 21 is sleeved with a spring 22. The spring 22 abuts against the bottom wall of each through groove 2 16 on the bottom surface of the guide block 20. One side of the guide block 20 is fixedly connected to the U-shaped block 8, and the other side is fixedly connected to the guide plate 14. The guide plate 14 abuts against the front side of the connecting block 13. Multiple equidistant scale lines 15 are opened on the outer side of the connecting block 13. The scale lines 15 are distributed on both sides of the through groove 2 16. The two ends of the guide plate 14 are sharpened. The end of the connecting block 13 is equipped with a grinder 17.

[0023] The front side of the column 5 is connected to the through groove 12. The T-shaped block 10 is movably connected in the through groove 12. The top surface of the T-shaped block 10 is vertically connected to the threaded hole 19. The threaded hole 19 is threaded with a screw 18. One end of the screw 18 is rotatably connected to the bottom wall of the through groove 12, and the other end is rotatably connected to the top wall of the through groove 12. The top surface of the column 5 is vertically fixed to the drive motor 11. The output end of the drive motor 11 is connected to the end of the screw 18. The U-shaped block 8 is fixedly connected to the T-shaped block 10. Two mirror-symmetrical guide holes 9 are vertically connected to each side of the U-shaped block 8. A smooth rod 7 is axially slidably connected in each guide hole 9. A support block 6 is fixed at each end of the smooth rod 7. The support block 6 is fixedly connected to the column 5.

[0024] Two pairs of mirror-symmetrical grooves 25 are horizontally opened on the top surface of the electromagnetic block 4. A spring 24 is horizontally fixed in each groove 25. The end of the spring 24 is fixedly connected to the slider 26. The slider 26 is slidably connected in the groove 25. The top surfaces of the two sliders 26 on the same side are jointly fixed with a clamping block 3. The two clamping blocks 3 are mirror-symmetrical front and back. The inner side of the two clamping blocks 3 is provided with a rubber sheet 23. The clamping blocks 3 are made of metal.

[0025] By connecting the grinding part to the U-block using spring 22, guide block 20, connecting block 13 and through groove 16, and opening scale line 15 on the outer side of connecting block 13, the workpiece is automatically separated from the grinding wheel after grinding, without the need for manual separation, thus avoiding excessive grinding of the workpiece and affecting the processing dimensions of the workpiece.

[0026] Working principle: In use, the workpiece is first clamped between two clamping blocks 3. Spring 24 is appropriately compressed, so that the clamping blocks 3 hold and fix the workpiece. Rubber sheet 23 increases the friction between the workpiece and the clamping blocks 3, preventing the workpiece from slipping and flying out during grinding. Then, the electromagnetic block 4 is energized, which generates magnetic force, fixing the clamping blocks 3 and the workpiece on the electromagnetic block 4. Then, the drive motor 11 drives the pull screw 18 to rotate. The screw 18 drives the U-shaped block 8 to descend through the T-shaped block 10. The U-shaped block 8 drives the connecting plate to descend. At the same time, the grinder 17 is started, so that the grinding wheel on the grinder 17 contacts the top surface of the workpiece for grinding. Spring 22 is compressed, and the friction between spring 22, guide block 20 and guide rod 24 is increased. Under the action of 1, the grinding machine 17 stops descending, the U-shaped block 8 continues to descend, and at the same time, it passes through the guide plate 14 at the position on the scale line 15, so that the scale of the guide plate 14 is the same as the required cutting thickness of the workpiece. After being accommodated, the drive motor 11 stops descending, and the grinding wheel will continue to grind the workpiece. As the total thickness of the workpiece continues to decrease, the spring 22, which is in a compressed state, will continuously reset. At the same time, the connecting block 13 carries the grinding machine 17 to continuously descend. When the grinding thickness of the workpiece reaches the standard, the spring 22 will be completely reset, and at the same time, the distance between the grinding wheel and the workpiece will increase, so that the grinding wheel and the workpiece will separate. Then, after the grinding machine 17 is turned off, the grinding machine 17 rises up, then the electromagnetic block 4 is turned off, and then the two clamping blocks 3 are separated, and the ground workpiece can be removed.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
