Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1 - Figure 3The utility model provides an embodiment: an automated friction pressure controlled grinding machine, comprising a grinder 1, which grinds a workpiece by means of a grinding belt. The structure is existing and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. A placing table 2 is slidably connected to the inner side of the grinder 1 for placing the workpiece to be polished. A slide rail 3 is fixedly connected to the inner side of the upper end of the grinder 1. The slide rail 3 is provided with two groups. An anti-slip groove is provided on the outer wall of a group of slide rails 3 near the front side. The moving block 41 can be quickly limited by using it in conjunction with a pressing sheet 46. The outer walls of the two groups of slide rails 3 are slidably connected to press down the grinding belt to realize pressure control. The adjustment component includes The movable block 41 is slidably connected to the outer side of the slide rail 3, which is used to drive the adjustment component to move stably. The inner wall of the middle part of the movable block 41 is slidably connected to the slide rod 42, which is used to make the lower plate 43 more stable when moving up and down. The bottom end of the slide rod 42 is fixedly connected to the lower plate 43, and the grinding belt is pressed down by the roller 52 above to achieve pressure control, thereby improving the grinding quality and efficiency. The inner wall of the top end of the lower plate 43 is rotatably connected to a threaded rod 44, and the outer wall of the upper end of the threaded rod 44 is connected to the inner wall of the front end of the movable block 41. The height of the lower plate 43 can be adjusted by rotating the threaded rod 44, which is convenient and fast. The inner wall on the right side of the front end of the movable block 41 is threadedly connected to a threaded rod 2 45, which drives the pressing plate 46 to move horizontally and stably.

[0034] Reference Figure 2 - Figure 4 The rear side of the threaded rod 45 is rotatably connected with a pressure plate 46, and an anti-skid strip is arranged on the rear side of the pressure plate 46. By cooperating with the anti-skid groove on the slide rail 3, the friction force can be increased, thereby improving the stability. The outer wall of the pressure plate 46 slides on the inner wall of the moving block 41, and the right inner wall of the lower plate 43 is slidably connected with a pull rod 47. A pull ring is arranged at the front end of the pull rod 47, which is convenient for workers to pull the pull rod 47. The pull rod 47 is elastically connected to the lower plate 43 through a compression spring 48, and the pull rod 47 is stably inserted into the inner wall of the limiting hole through the compression spring 48, thereby improving the stability of the extension plate 49. The right inner wall of the lower plate 43 is slidably connected with an extension plate 49. By pulling the extension plate 49 out of the lower plate 43, the length of the pressed grinding belt can be adjusted to adapt to workpieces of different specifications. A limiting hole is provided at the front end of the extension plate 49 near the rear side of the pull rod 47, and the outer wall of the rear side of the pull rod 47 slides on the inner wall of the limiting hole.

[0035] Reference Figure 5 and Figure 6A disassembly assembly is provided on the left inner wall of the lower plate 43, and the disassembly assembly includes a limit plate 51. The outer wall of the top end of the limit plate 51 is slidably connected to the left inner wall of the lower plate 43. A bearing is provided on the inner wall of the rear side of the limit plate 51. The bearing makes the roller 52 rotate more smoothly and reduces the wear on the roller 52. The inner wall of the bearing is plugged with a roller 52. The roller 52 is set to a rubber material, which can reduce the damage to the grinding belt. The two sides of the grinding belt are squeezed by two groups of rollers 52, so that the grinding belt can fully contact the workpiece and grind the workpiece. The rear side of the roller 52 is plugged into the bearing at the bottom end of the lower plate 43.

[0036] Reference Figure 6 and Figure 7 The lower plate 43 is slidably connected with a limiting block 53 near the front end of the limiting plate 51. The bottom end of the limiting block 53 is set as an inclined surface, which can more conveniently squeeze and limit the limiting plate 51. The front end of the limiting block 53 is slidably connected with a clamping block 54. The front end of the clamping block 54 slides on the inner wall of the lower plate 43, which can improve the limiting effect of the limiting block 53. The clamping block 54 is elastically connected to the limiting block 53 through a reset spring 55. The elastic force of the reset spring 55 can release the clamping block 54 from limiting the limiting block 53. Two groups of disassembly components are provided, and the other group of disassembly components is provided on the inner wall of the right side of the expansion plate 49, which improves the efficiency of maintenance operations, greatly reduces downtime, and further improves production efficiency and convenience of operation.

[0037] Working principle: when in use, first move the moving block 41 on the slide rail 3 according to the specifications of the workpiece to be processed. At this time, rotate the threaded rod 45 to make the threaded rod 45 drive the pressure plate 46 to move horizontally, so that the anti-slip strip on the pressure plate 46 contacts the slide rail 3 to limit the moving block 41. At this time, rotate the threaded rod 44 again to make the lower plate 43 drive the slide rod 42 to slide on the inner wall of the moving block 41, and adjust the height of the lower plate 43. Then pull the pull rod 47 forward to squeeze the compression spring 48 so that the pull rod 47 slides out from the inner wall of the limiting hole to release the limitation of the expansion plate 49. At this time, pull the expansion plate 49 out and stretch it according to the specifications of the workpiece. At this time, release the pull rod 47 and slide the pull rod 47 into the inner wall of another set of limiting holes through the elastic force of the compression spring 48 to limit the expansion plate 49, so that the two sets of rollers 52 squeeze the grinding belt downward so that the grinding belt fits the workpiece. At this time, the grinder 1 can be started to grind the workpiece.

[0038] When the roller 52 needs to be replaced, the limiting block 53 is first pulled upward to make the blocking block 54 slide into the inner wall of the limiting block 53, and the return spring 55 is squeezed to release the limitation on the limiting block 53. At this time, the limiting block 53 is pulled out to release the limitation on the limiting plate 51. The limiting plate 51 is pulled forward to release the limitation on the roller 52. At this time, the roller 52 can be quickly replaced, which improves the efficiency of maintenance operations, greatly reduces downtime, and further improves production efficiency and operational convenience.
