Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment, in particular to a precision grinding device for forklift accessories. Background Art

[0002] The forklift drum brake is a component of the forklift accessories. It consists of a brake drum and a tailgate assembly. The brake drum is connected to the axle, and the tailgate assembly is connected to the chassis of the vehicle. The tailgate assembly contains brake shoes and springs. When the brake shoe contacts the inner wall of the brake drum and generates friction, the forklift can be braked.

[0003] When the brake shoe is in contact with the brake drum for a long time, a step groove will be generated on the surface where the inner wall of the brake drum contacts the brake shoe. When the maintenance personnel replace the new brake shoe, the step groove needs to be ground off. When the maintenance personnel grind off the step groove, the conventional tool is to replace the cutting disc of the handheld cutting machine with a grinding disc to grind the step groove. However, since the brake drum is round, it is difficult to grind the step groove flat using a handheld cutting machine. To this end, we propose a precision grinding device for forklift accessories.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0025] Reference Figure 1-5 A precision grinding device for forklift accessories includes a positioning plate 1. A positioning hole 15 is opened on the surface of the positioning plate 1. The positioning hole 15 corresponds to the mounting hole position on the surface of the forklift brake drum 18. The positioning plate 1 is placed on the brake drum 18, and the positioning hole 15 is aligned with the mounting hole position on the brake drum 18. After that, the positioning plate 1 and the brake drum 18 can be fixed as a whole by using external bolts.

[0026] A grinding structure for grinding the forklift brake drum is provided at one end of the positioning disk 1. The grinding structure includes a grinding ball 2 and an adjusting component for adjusting the position of the grinding ball 2. The adjusting component includes a threaded rod 3. A first connecting plate 4 is fixedly installed at one end of the threaded rod 3. A second connecting plate 5 is sleeved on the surface of the threaded rod 3. A plurality of first connecting rods 6 and second connecting rods 7 are hinged on the surfaces of the first connecting plate 4 and the second connecting plate 5 in a circular array, respectively. The opposite surfaces of the first connecting rod 6 and the second connecting rod 7 are hinged to each other. A mounting seat 8 is fixedly installed on the surface of the first connecting rod 6. The grinding ball 2 is rotatably installed on the inner wall of the mounting seat 8. Pushing the second connecting plate 5 downward can drive the second connecting plate 5 to slide along the surface of the threaded rod 3, thereby driving the first connecting rod 6 and the second connecting rod 7 to rotate relative to each other and forcing the plurality of grinding balls 2 to open. Conversely, pushing the second connecting plate 5 upward can drive the plurality of grinding balls 2 to be retracted, thereby facilitating the storage of the device when not in use.

[0027] The surface of the threaded rod 3 is provided with a limiting assembly that can limit the second connecting plate 5. The limiting assembly includes two adjusting nuts 13 that are both threadedly connected to the surface of the threaded rod 3, and the two adjusting nuts 13 are respectively located on both sides of the second connecting plate 5. When the position of the second connecting plate 5 is adjusted, the two adjusting nuts 13 are rotated to drive the two adjusting nuts 13 to contact the second connecting plate 5, so that the second connecting plate 5 can be fixed.

[0028] The other end of the positioning disk 1 is provided with an assembly structure that can assemble the grinding structure and the positioning disk 1 as one. The assembly structure includes an assembly cylinder 9 rotatably installed at the center position of the positioning disk 1. The inner wall of the assembly cylinder 9 is provided with a spring jacket 10. The shape of the spring jacket 10 is set to be conical, and the inner wall of the assembly cylinder 9 is provided with a conical groove 14 that matches the spring jacket 10. The surface of the assembly cylinder 9 is threadedly connected with a locking nut 11, and the end of the first connecting disk 4 away from the threaded rod 3 is fixedly connected with an adjusting rod 12. The inner diameter of the spring jacket 10 is matched with the outer diameter of the adjusting rod 12. The adjusting rod 12 is inserted into the spring jacket 10, and then the locking nut 11 is tightened, so that the spring jacket 10 can be driven to move upward and contact with the conical groove 14, thereby forcing the spring jacket 10 to contract and clamp the adjusting rod 12, and then the grinding structure and the positioning disk 1 can be assembled as one.

[0029] A motor 16 is fixedly installed on the upper end of the threaded rod 3, and a handle 17 is fixedly installed on the surface of the motor 16. When the grinding structure and the positioning plate 1 are assembled as one, the motor 16 is then driven to drive the threaded rod 3 to rotate, thereby forcing the grinding ball 2 to rotate to grind the brake drum 18. At the same time, the adjusting rod 12 is slid along the inner wall of the assembly tube 9, thereby changing the depth of the grinding ball 2 on the inner wall of the brake drum 18, thereby grinding multiple positions of the inner wall of the brake drum 18.

[0030] Compared with the prior art, the device uses a positioning plate 1 to fix the brake drum 18 as a whole, and then uses an adjusting component to drive the grinding balls 2 to contact the inner wall of the brake drum 18. Then the driving motor 16 drives multiple grinding balls 2 to rotate along the axis of the threaded rod 3, so that the inner wall of the brake drum 18 can be evenly and smoothly polished, thereby improving the flatness of the polished surface.

[0031] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
