Description

Technical Field

[0001] The present application belongs to the technical field of drill bit grinding processing, and in particular relates to a hollow drill bit grinding operation device. Background Art

[0002] The drills used in existing binding machines are prone to paper scraps becoming clogged during drilling. Due to the length of the drill holes, the paper scraps cannot be directly removed. The drill must be shaken vigorously to expel the paper scraps. This method of operation is prone to slippage or bumping, making it inefficient and unsafe. Furthermore, existing drills cannot be fixed for grinding, making the operation inconvenient and prone to operator injury. This poses a significant safety risk, reduces grinding efficiency, and can even cause secondary damage to the drill. Summary of the Invention

[0003] The present application provides a hollow drill bit grinding operation device. The existing manual grinding of drill bits is inconvenient, not only inefficient but also with high safety risks and easily causing secondary damage to the drill bit.

[0008] The grinder can pass through the through hole away from one end of the drill bit and directly contact the drill bit edge when the drill bit passes through the through hole and is fixed in the fixing member, and rotate the grinder to grind the drill bit edge.

[0009] Furthermore, the length of the drill bit is shorter than the length of the fixing piece.

[0010] Furthermore, it also includes a positioning piece that cooperates with the positioning hole set on the wall surface of the fixing piece. The positioning piece passes through the positioning hole until it contacts the wall surface of the handle of the drill inserted into the through hole, so that the drill is fixed in the through hole.

[0011] Furthermore, the positioning member is arranged perpendicular to the wall surface of the fixing member and is configured at one end of the fixing member; and the positioning hole is configured to pass through at least one side wall surface of the fixing member.

[0012] Furthermore, an anti-slip film is provided on the outer wall surface of the fixing member. The anti-slip film is configured to half-cover or fully cover the wall surface of the fixing member and is arranged in a different position from the positioning hole.

[0013] Furthermore, the grinder further comprises a grinding rod for fixing the grinding knife and a grinding seat integrally constructed with the grinding rod, wherein the diameter of the grinding seat is larger than the diameter of the through hole.

[0014] Furthermore, the sum of the lengths of the grinding rod and the drill bit is greater than the length of the through hole.

[0015] Preferably, it is also equipped with a chip ejector for chip removal, which is provided with a push rod head; when the drill passes through the through hole and is fixed in the fixing member, the chip ejector can pass through the end of the through hole away from the drill and be inserted into the drill, and the paper chips placed in the drill are repeatedly pushed against by the push rod head, so that the paper chips can be discharged from the end of the drill away from the chip ejector.

[0016] Furthermore, the chip ejector includes a top seat and a stepped rod placed on the top seat, the stepped rod includes a top rod head and a transition rod, the diameter of the top rod head is smaller than the inner hole diameter of the drill bit; the diameter of the transition rod is smaller than the through hole diameter and larger than the inner hole diameter of the drill bit; the top seat is larger than the through hole diameter.

[0030] The present application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] This embodiment provides a hollow drill grinding operation device, such as Figure 1 As shown, the device includes a fixing member 20 and a positioning member 30 for fixing the position of the drill bit 10, a chip ejector 40 that cooperates with the fixing member 20 and is used to push paper scraps out of the drill bit 10, and a grinder 50 that cooperates with the fixing member 20 and is used to grind the cutting edge of the drill bit 10. The fixing member 20 is provided with a through hole along its length; the chip ejector 40 is provided with a push rod head 41; and the grinder 50 is provided with a grinding blade 51. The operating device proposed in this application is not only ingeniously designed and simple in structure, but can also both grind the drill bit and quickly remove paper scraps stuck in the drill bit. The entire operation does not require changing the drill bit's fixed position, resulting in high versatility, high reliability, quick, convenient, and safe operation. Simply by cooperating with the fixing member 20, the chip ejector 40, and the grinder 50, paper scraps stuck in the drill bit 10 can be quickly removed. Furthermore, the drill bit 10 can be accurately ground without changing the drill bit's fixed position, resulting in quick, convenient, and safe operation. The direction in which the drill bit 10 is inserted into the fixing member 20, and the direction in which the chip ejector 40 and the grinder 50 cooperate with the fixing member 20 are as follows: Figure 1 As indicated by the arrow in .

[0032] like Figure 2 As shown, the fixing member 20 is a sleeve structure comprising a body 21 with a through hole. A positioning hole 22, which is an internally threaded hole, is provided at one end of the body 21. It also includes a positioning member 30, which is a set screw, that engages with the positioning hole 22. The positioning member 30 can pass through the positioning hole 22 until it contacts the handle of the drill 10 inserted into the through hole, securing the drill 10 within the through hole. The overall length of the drill 10 is shorter than the length of the fixing member 20, preventing the cutting edge of the drill 10 from protruding beyond the fixing member 20 and potentially injuring the operator, thereby improving operational safety.

[0033] The positioning member 30 is disposed perpendicular to the wall surface of the fixing member 20 and is configured at one end of the fixing member 20. It primarily contacts the handle of the drill bit 10, thereby securing the drill bit 10 within the through-hole along the length of the fixing member 20. The positioning hole 22 is provided on at least one side surface of the body 21. Preferably, it is configured to pass through both walls of the body 21, that is, through the body 21, so that the drill bit 10 can be secured within the through-hole from both sides.

[0034] Preferably, to enhance operational safety of the fixing member 20, an anti-slip film 23 is provided on the outer wall of the body 21. The anti-slip film 23 may be an open structure mating with the body 21, such as a rubber sleeve; or it may be a patterned surface directly engraved on the wall of the body 21, partially covering the wall of the body 21, or fully covering the wall of the body 21. Regardless of the structure of the anti-slip film 23, it must be positioned offset from the positioning hole 22 to avoid interfering with the fixation of the drill bit 10 during operation.

[0035] When the drill bit 10 passes through the through hole and is fixed in the fixing member 20, the chip ejector 40 can pass through the through hole away from the end of the drill bit 10 and be inserted into the drill bit 10. The paper scraps placed in the drill bit 10 can be repeatedly pushed against by the ejector head 41, and the paper scraps can be discharged from the end of the drill bit 10 away from the chip ejector 40.

[0036] like Figure 3 , which is a cross-sectional view of the chip ejector and drill bit during chip removal. As can be seen from this figure, the chip ejector 40 includes a top seat 43 and a stepped rod disposed on and integrally formed with the top seat 43. The stepped rod includes a rod head 41 and a transition rod 42. The diameter of the rod head 41 is smaller than the inner diameter of the drill bit 10.

[0037] Preferably, the diameter of the push rod head 41 is 1 / 2-3 / 4 of the inner diameter of the drill bit 10 ; it cannot be too thin, otherwise it cannot contact the paper scraps; nor can it be too thick, otherwise it will damage the inner diameter wall surface of the drill bit 10 .

[0038] The diameter of the transition rod 42 is smaller than the diameter of the through hole and larger than the inner diameter of the drill 10, thereby increasing the length of the chip ejector 40 extending into the through hole without affecting the fit between the ejector head 41 and the drill 10. The ejector seat 53 is larger than the diameter of the through hole, and the wall chip ejector 40 is directly inserted into the fixing member 20 and cannot be removed, thereby improving the safety of the chip ejector 40 operation.

[0039] Preferably, the length of the ejector head 41 is at least half the length of the section where the cutting edge of the drill bit 10 is located, increasing the length of the ejector chip to improve the efficiency and quality of paper scrap removal. The combined length of the ejector head 41 and the drill bit 10 is greater than the length of the through hole to enhance ease of engagement and enable quick and precise operation.

[0040] like Figure 4, which illustrates the coordination between the grinder 50 and the drill 10 during grinding. The grinder 40 also includes a grinding rod 52 for securing the grinding tool 51 and a grinding base 53 integrally formed with the grinding rod 52. The diameter of the grinding base 53 is larger than the diameter of the through hole, enhancing the safety and reliability of the operation of the grinder 50. The combined length of the grinding rod 52 and the drill 10 is greater than the length of the through hole, increasing the length of the grinding tool 51 that can be inserted into the through hole, facilitating contact between the grinding tool 51 and the cutting edge of the drill 10.

[0041] When paper scraps are trapped in the drill bit 10, the chip ejector 40 can be used to remove the paper scraps. The grinder 50 can then be used to grind the cutting edge of the drill bit 10. When there are no paper scraps in the drill bit 10, the grinder 50 can pass through the through-hole, away from the end of the drill bit 10, and directly contact the cutting edge of the drill bit 10 when the drill bit 10 passes through the through-hole and is secured in the fixture 20. The grinder 51 rotates to grind the cutting edge of the drill bit 10.

[0042] A hollow drill bit grinding operation device designed by the present application has an ingenious and simple structural design. The paper scraps stuck in the drill bit can be quickly cleaned out through the chip ejector, and the drill bit can be accurately ground by the grinder without changing the drill bit state. It is quick, convenient and safe to operate.

[0043] The above embodiments of the present application are described in detail. The contents described are only preferred embodiments of the present application and should not be considered to limit the scope of implementation of the present application. All equivalent changes and improvements made within the scope of the present application should still fall within the scope of the patent application.
