DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0027] Referring to Figures 1-5 The utility model discloses a forklift hub drilling clamp, including base 1, top cover 2, fastening bolt 3, base 1 includes the inner side through slot 104 in the middle inside and the first through hole 103 at the inner side through slot 104 around, the inner diameter of inner side through slot 104 and the outer diameter of hub lower part correspond consistently, when using, the lower part of hub is covered into inner side through slot 104, prevents the horizontal movement of undrilled hub 5, and the number and position of first through hole 103 are arranged according to the predetermined hole position on drilled hub 4, and one side of base 1 is provided with first positioning structure for positioning top cover 2;

[0028] Top cover 2 includes the third through hole 203 corresponding with inner side through slot 104, the second through hole 202 corresponding with first through hole 103, the second limiting structure for limiting undrilled hub 5, and the center hole of inner side through slot 104, third through hole 203 and undrilled hub 5 is on the same axis, and the inner diameter of third through hole 203 and the outer diameter size of fastening bolt 3 correspond consistently, when drilling drill wears undrilled hub 5, the head portion of drill bit is inserted into second through hole 202;

[0029] The second limiting structure limits undrilled hub 5, prevents undrilled hub 5 from moving, the first limiting structure limits top cover 2, prevents top cover 2 from moving, thereby fixes undrilled hub 5, and then drill bit is inserted into first through hole 103 and drills the upper top wall of undrilled hub 5.

[0030] The fastening bolt 3 is inserted into the inner through groove 104 and the third through hole 203 to fix the base 1 and the top cover 2 on the T-slot workbench. The fastening bolt 3 is equipped with a fastening nut. When in use, the hexagonal head of the fastening bolt 3 is first inserted into the T-slot of the workbench, and then the base 1, the un-drilled hub 5, and the top cover 2 are sequentially put on the fastening bolt 3. The fastening nut is tightened to clamp and fix the un-drilled hub between the base 1 and the top cover 2.

[0031] The base 1 also includes a seat body 101. The first through hole 103 and the inner through groove 104 are both opened on the seat body 101. The first limiting mechanism includes a side plate 105 fixedly installed on the seat body 101. A tightening bolt 106 is installed on the side plate 105. The side wall of the top cover 2 is provided with an abutment hole 208 corresponding to the tightening bolt 106. When the tightening bolt 106 is tightened and abuts against the abutment hole 208, it can prevent the top cover 2 from rotating in the horizontal direction.

[0032] The top cover 2 also includes a cover body 201. The second through hole 202 and the third through hole 203 are opened on the cover body 201. The bottom of the cover body 201 is integrally formed with a limiting block 204. The inside of the limiting block 204 is provided with a hub groove 209 corresponding to the outer contour of the un-drilled hub 5. The abutment hole 208 is opened on the side wall of the limiting block 204. Since the shape of the un-drilled hub 5 is a regular set of shapes similar to a pentagon, the hub groove 209 corresponds to the shape of the un-drilled hub 5. The depth of the hub groove 209 is not greater than the height of the un-drilled hub 5. Therefore, when the hub groove 209 is fitted on the un-drilled hub 5, it can also prevent the un-drilled hub 5 from rotating in the horizontal direction.

[0033] The abutment hole 208 penetrates the side wall of the limiting block 204. After the tightening bolt 106 is inserted into the abutment hole 208, its end abuts against the outer side wall of the un-drilled hub 5, tightening the un-drilled hub 5. This is used to eliminate the gap between the un-drilled hub 5 and the hub groove 209 and improve the machining accuracy.

[0034] The base 1 has ear plates 102 integrally formed on both sides, and ear plate bolts 107 are screwed onto the ear plates 102. The base 1 is also fixed to the T-slot workbench by the ear plate bolts 107, making it more stable.

[0035] Handles 206 are welded on both sides of the top cover 2, making it easy for workers to lift the top cover 2 with both hands.

[0036] The inner diameter of the third through hole 203 corresponds to the outer diameter of the fastening bolt 3. When the top cover 2 is fitted onto the fastening bolt 3 and the top cover 2 is fixed, the top cover 2 can also limit the fastening bolt 3 through the third through hole 203 to prevent the upper end of the fastening bolt 3 from swinging.

[0037] The top of the third through hole 203 movably mounts a U-shaped pad 207, the inner diameter of the U-shaped pad 207 corresponds to the outer diameter of the fastening bolt 3, and a fastening nut is located on the top of the U-shaped pad 207, and the U-shaped pad 207 is used to replace the cover body 201 and contact the fastening nut to reduce the abrasion of the cover body 201 during the fastening nut is tightened or loosened.

[0038] In the present application, the base 1 and the top cover 2 are both made of untempered ordinary cast iron, which is convenient for casting and manufacturing and reduces the cost while avoiding the abrasion of the hub surface.

[0039] Working principle: when in use, the un-drilled hub 5 is placed on the base 1, the lower part of the un-drilled hub 5 is sleeved into the first through hole 103, the fastening bolt 3 passes through the center hole of the un-drilled hub 5, the top cover 2 is placed on the un-drilled hub 5, the top cover 2 is rotated to align the hub groove 209 with the un-drilled hub 5 and sleeve the un-drilled hub 5 outside, the top cover 2 is continuously rotated to drive the un-drilled hub 5 to rotate synchronously, the clamping bolt 106 is aligned with the abutting hole 208, the clamping bolt 106 is tightened, the U-shaped pad 207 is sleeved on the top of the fastening bolt 3, and finally the fastening nut 301 is tightened on the fastening bolt 3, so that the un-drilled hub 5 is clamped, the drill bit of the drilling machine penetrates into the first through hole 103 to drill the un-drilled hub 5 to form the fourth through hole 401, and the drilled hub 4 is obtained.

[0040] The above describes only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
