Description

Technical Field

[0001] This utility model belongs to the technical field of anti-breakage hexagonal shank iron cobalt drills, specifically an anti-breakage hexagonal shank iron cobalt drill. Background Technology

[0002] A hexagonal shank twist drill is a type of twist drill with a hexagonal shank. Compared to a round shank, the hexagonal shank can be more firmly held in power tools or drill chucks, effectively preventing the drill bit from slipping during drilling and ensuring drilling accuracy and stability.

[0003] Most hexagonal shank twist drills on the market have a fixed and simple structure. When the hexagonal shank twist drill is working, the front end of the drill bit is the part that mainly bears the impact force and wear. During use, due to the high speed of the machine rotating the drill rod, the drill bit is easily broken when subjected to large forces. This causes inconvenience to the workers in processing the workpiece, reduces the workers' work efficiency, and prolongs the workers' working time.

[0004] Therefore, a fracture-resistant hexagonal shank cobalt drill is proposed to address the above problems. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a fracture-resistant hexagonal shank twist drill, which has the advantage of being able to prevent fracture of the hexagonal shank twist drill during operation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fracture-resistant hexagonal shank cobalt drill, comprising a hexagonal shank cobalt drill body, wherein a shank is provided at one end of the hexagonal shank cobalt drill body, and a fracture-resistant component is installed inside the hexagonal shank cobalt drill body.

[0007] The anti-breakage component includes a reinforcing rod, which is snapped into the interior of the hexagonal shank cobalt drill body. A fixed rod is installed inside the reinforcing rod. A movable rod is rotatably connected to a groove on the surface of the fixed rod. A reinforcing strip is installed on the surface of the movable rod, with one end of the reinforcing strip abutting against the interior of the reinforcing rod. A sleeve rod is installed inside the fixed rod, and a reinforcing top rod is slidably connected inside the sleeve rod. One end of the reinforcing top rod abuts against the interior of the reinforcing rod. A disassembly component is installed on the surface of the reinforcing rod.

[0008] Preferably, a torsion spring is fitted onto the surface of the movable rod, one end of which is installed in a groove on the surface of the fixed rod, and the other end of which is connected to the reinforcing strip.

[0009] Preferably, a return spring is sleeved on the surface of the reinforcing top rod, one end of the return spring is connected to the reinforcing top rod, and the other end of the return spring is installed inside the sleeve rod.

[0010] Preferably, the reinforcing rod, reinforcing strip, and reinforcing top rod are all made of metal steel.

[0011] Preferably, the disassembly assembly includes a connecting plate, one end of the reinforcing rod is fitted with the connecting plate, the connecting plate is in contact with the shank, and support plates are symmetrically installed on the surfaces of the shank and the hexagonal shank cobalt drill body, with threaded rods inserted into the surfaces of the support plates.

[0012] Preferably, both ends of the threaded rod pass through the support plate and extend to the outside of the support plate, and are threadedly connected to a nut disposed on the outside of the support plate.

[0013] Preferably, a plug is installed on the side surface of the connecting disc near the handle, and the plug is inserted into a socket opened on the surface of the handle.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model incorporates an anti-breakage component. To prevent breakage of the hexagonal shank cobalt drill body, a reinforcing rod is first engaged inside the drill body. During operation, the reinforcing rod strengthens the entire drill body. The fixing rod within the reinforcing rod further enhances overall strength. A reinforcing strip on the movable rod within the groove of the fixing rod abuts against the reinforcing rod, providing overall support and significantly increasing its strength. Furthermore, the reinforcing top rod inside the sleeve also abuts against the reinforcing rod, preventing deformation and further enhancing its overall strength. This ensures the hexagonal shank cobalt drill body remains intact during operation.

[0016] 2. This utility model incorporates a disassembly assembly. When disassembling and replacing the reinforcing rod, first rotate the nuts at both ends of the threaded rod to disengage them from the surface of the threaded rod. Then, pull the threaded rod to disengage it from the connecting plate and the support plate. Finally, pull the connecting plate, which causes the insertion block to disengage from the insertion hole on the surface of the handle, thereby enabling the disassembly and replacement of the reinforcing rod.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 5 As shown, this utility model provides a fracture-resistant hexagonal shank cobalt drill, including a hexagonal shank cobalt drill body 1, a shank 12 is provided at one end of the hexagonal shank cobalt drill body 1, and a fracture-resistant component 2 is installed inside the hexagonal shank cobalt drill body 1.

[0025] The anti-breakage component 2 includes a reinforcing rod 21. The reinforcing rod 21 is snapped into the interior of the hexagonal shank cobalt drill body 1. A fixing rod 22 is installed inside the reinforcing rod 21. A movable rod 23 is rotatably connected in a groove on the surface of the fixing rod 22. A reinforcing strip 24 is installed on the surface of the movable rod 23. One end of the reinforcing strip 24 abuts against the interior of the reinforcing rod 21. A sleeve rod 25 is installed inside the fixing rod 22. A reinforcing top rod 26 is slidably connected inside the sleeve rod 25. One end of the reinforcing top rod 26 abuts against the interior of the reinforcing rod 21. A disassembly component 3 is installed on the surface of the reinforcing rod 21.

[0026] Specifically, such as Figure 1As shown, a torsion spring 27 is fitted on the surface of the movable rod 23. One end of the torsion spring 27 is installed in a groove on the surface of the fixed rod 22, and the other end of the torsion spring 27 is connected to the reinforcing strip 24. A return spring 28 is fitted on the surface of the reinforcing top rod 26. One end of the return spring 28 is connected to the reinforcing top rod 26, and the other end of the return spring 28 is installed inside the sleeve rod 25. The reinforcing rod 21, the reinforcing strip 24, and the reinforcing top rod 26 are all made of metal steel.

[0027] In this implementation scheme: When preventing the hexagonal shank iron cobalt drill body 1 from breaking, the reinforcing rod 21 is first snapped into the inside of the hexagonal shank iron cobalt drill body 1. When the hexagonal shank iron cobalt drill body 1 is working, the reinforcing rod 21 can reinforce the entire hexagonal shank iron cobalt drill body 1. The fixing rod 22 inside the reinforcing rod 21 can further improve the overall strength. The reinforcing strip 24 on the movable rod 23 in the groove inside the fixing rod 22 abuts against the reinforcing rod 21, so as to support the entire reinforcing rod 21, thereby greatly improving the overall strength of the reinforcing rod 21. The reinforcing top rod 26 inside the sleeve rod 25 also abuts against the reinforcing rod 21, thereby preventing the reinforcing rod 21 from deforming and further improving the overall strength of the reinforcing rod 21, so that the hexagonal shank iron cobalt drill body 1 can avoid breaking during operation.

[0028] When the reinforcing rod 21 is subjected to a large force, the movable rod 23 drives the reinforcing strip 24 to rotate, thereby adjusting the support according to the force. When the movable rod 23 rotates, it causes the torsion spring 27 to deform. The torsion spring 27 can reset the position of the reinforcing strip 24, so that the reinforcing strip 24 always abuts against the inside of the reinforcing rod 21. At the same time, the reinforcing top rod 26 slides in the sleeve rod 25. The reinforcing top rod 26 then causes the return spring 28 to deform. The return spring 28 can ensure that the reinforcing top rod 26 always abuts against the inside of the reinforcing rod 21, thereby improving the anti-breakage effect of the device during use.

[0029] Please refer to Example 2 Figures 1-5 The difference between this embodiment and embodiment 1 is that the disassembly assembly 3 includes a connecting plate 31, one end of the reinforcing rod 21 is fitted with the connecting plate 31, the connecting plate 31 is in contact with the shank 12, and the surfaces of the shank 12 and the hexagonal shank iron cobalt drill body 1 are symmetrically fitted with support plates 32, and threaded rods 33 are inserted into the surface of the support plates 32.

[0030] Specifically, such as Figure 1-5 As shown, both ends of the threaded rod 33 pass through the support plate 32 and extend to the outside of the support plate 32, and are threadedly connected to the nut 34 located on the outside of the support plate 32. A plug-in block 35 is installed on the side surface of the connecting plate 31 near the handle 12, and the plug-in block 35 is inserted into the plug hole opened on the surface of the handle 12.

[0031] In this implementation scheme: when the reinforcing rod 21 is disassembled and replaced, first rotate the nuts 34 at both ends of the threaded rod 33 so that the nuts 34 are disengaged from the surface of the threaded rod 33. Then pull the threaded rod 33 so that the threaded rod 33 is disengaged from the connecting plate 31 and the support plate 32. Then pull the connecting plate 31 so that the connecting plate 31 drives the plug block 35 to disengage from the plug hole opened on the surface of the handle 12, thereby realizing the disassembly and replacement of the reinforcing rod 21.
