[0022] Embodiment 1
[0023] like Figure 1 , Figure 2 , Figure 3As shown, a countersink replaceable lower die tooling for a bench drill is installed on a bench drill table 7 and is located directly below the drill bit of the bench drill. The countersink replaceable lower die tooling for a bench drill comprises a fixed block 1, a replaceable lower die 2, and a hand screw. The fixed block 1 is fixed to the bench drill table 7 in any fixing manner; the fixed block 1 is a rectangular block, so the structure is simple and easy to manufacture and process; a replacement hole 3 is provided in the middle of the fixed block 1, which is a round hole penetrating the fixed block 1; a tightening hole 4 is provided in the middle of the front of the fixed block 1, which is a threaded hole, and the tightening hole 4 is vertically connected to the replacement hole 3. The replaceable lower die 2 is located directly below the drill bit of the bench drill. The replaceable lower die 2 includes a first auxiliary section 21, a main section 22, and a second auxiliary section 23 which are connected in sequence as a whole. The three are cylindrical, and the diameter of the main section 22 is larger than the diameter of the first auxiliary section 21 and the second auxiliary section 23. The combination of the three or the entire replaceable lower die 2 is in the shape of a stepped shaft, so that the structure is simple and easy to manufacture and process; the first auxiliary section 21 or the second auxiliary section 23 is sleeved in the replacement hole 3, and the structural shapes are adapted to each other; the end face of the main section 22 is in contact with and fits with the upper surface of the fixed block 1; the replaceable lower die 2 is fixed in the replacement hole 3 by screwing the hand screw into the tightening hole 4 and squeezing the first auxiliary section 21 or the second auxiliary section 23 by the end of the hand screw.
[0024] In this embodiment, an annular recessed groove 5 is respectively provided on the first auxiliary section 21 and the second auxiliary section 23; after the hand screw thread is screwed into the tightening hole 4, the end of the hand screw is stuck in the annular recessed groove 5, and the annular recessed groove 5 of the first auxiliary section 21 or the second auxiliary section 23 is squeezed by the end of the hand screw, so that the replaceable lower mold 2 is fixed in the replacement hole 3; in this way, it is convenient to fix the replaceable lower mold 2, to enhance the structural stability, and at the same time to disassemble, assemble and replace the replaceable lower mold 2, which is easier to use.
[0025] In this embodiment, a first auxiliary hole 24 is provided in the first auxiliary section 21, and a second auxiliary hole 25 is provided in the second auxiliary section 23. The diameter of the second auxiliary hole 25 is larger than the diameter of the first auxiliary hole 24. The ends of the first auxiliary hole 24 and the second auxiliary hole 25 extend into the main section 22 respectively, and the first auxiliary hole 24 and the second auxiliary hole 25 are connected. The two auxiliary holes play an auxiliary processing role such as avoiding position during countersinking processing; at the same time, by setting two auxiliary holes of different diameters, the tooling can be adjusted according to the size of different countersinks (or different bench drill bits), that is, the replaceable lower mold 2 can be assembled upside down or right side up, so that the applicability of the tooling is stronger.
[0026] The working process of this embodiment is as follows: after the entire tool is installed on the bench drill table 7 and is placed directly below the bench drill bit, the special-shaped product (such as a plate with an uneven surface) is clamped by hand or with a tool and placed on the upper surface of the first auxiliary section 21 or the second auxiliary section 23 of the replaceable lower die 2, and then the bench drill bit is used to press down to perform countersinking processing. In this way, the tool can assist in the countersinking processing of special-shaped products and is easy to use; the replaceable lower die 2 can be disassembled and replaced by unscrewing the hand screws. In this way, the lower die of the tool can be quickly replaced with low cost.
[0027] The beneficial effects of this embodiment are: this tooling can assist in the countersinking processing of special-shaped products, is easy to use, the lower mold can be quickly replaced, the cost is low, the structure is simple and compact, and it is easy to manufacture and disassemble.
[0028] Embodiment 2
[0029] The difference between this embodiment and the first embodiment is that a plurality of fixing holes 6 are provided at the bottom of the fixing block 1 , and the fixing holes 6 are regularly distributed along the length direction of the fixing block 1 .
[0030] In this embodiment, a waist-shaped hole 71 is respectively provided at both ends of the bench drill table 7, and each waist-shaped hole 71 is aligned with a fixing hole 6 in the upper and lower parts; bolts and stud fasteners are used to pass through the waist-shaped holes 71 from the bottom of the bench drill or from the bottom of the bench drill table 7, and are threadedly connected with the fixing holes 6, so that the fixing block 1 is fixed to the bench drill table 7. For bench drill tables 7 of different sizes, the spacing between the waist-shaped holes 71 at both ends is different. By setting a plurality of fixing holes 6 regularly distributed along the length direction of the fixing block 1, it can adapt to bench drills of different specifications, and can be fixed and installed according to the spacing between the waist-shaped holes 71 on different bench drill tables 7, so that the tooling has stronger applicability and a wider range of applications.
[0031] The beneficial effects of this embodiment are: the tooling has stronger applicability, wider application range, simple structure, easy manufacturing and processing, and low cost.
[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the protection scope of the claims.
