Description

Technical Field

[0001] This utility model relates to the field of deep hole drilling technology, specifically to an auxiliary device for high-precision deep hole drilling. Background Technology

[0002] A deep hole drill is a drill bit specifically designed for machining deep holes. Its drill rod is slender and has poor rigidity, making it prone to bending and vibration. Currently, deep hole drills are mainly used in the field of mold processing technology.

[0003] The Chinese Patent Network discloses an auxiliary device for high-precision deep hole drilling, publication number CN220006107U. Although the U-shaped base, sliding frame, spring, and sleeve can prevent problems such as drill bit vibration, ripples, and taper in the early stage of drilling by the sleeve restriction during deep hole machining, thus improving the accuracy of deep hole machining, the spring's rebound force pushes the sliding frame to automatically reset when the device moves away from the workpiece after drilling. The fluid filling holes symmetrically opened on both sides of the bottom of the sliding frame can add cutting fluid and lubricant into the sleeve, which can reduce the wear of the drill bit during deep hole machining. However, since the sleeve is fixed on the sliding frame during operation, it is not convenient to disassemble the sleeve, making it difficult to clean the debris inside the sleeve. The debris may cause the sleeve to become clogged, thus affecting the working efficiency of the drill bit.

[0004] To address this, an auxiliary device for high-precision deep hole drilling is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary device for high-precision deep hole drilling.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0030] Example 1:

[0031] Please see Figure 1-4 This utility model provides a technical solution: To achieve the above objectives, this utility model provides the following technical solution: An auxiliary device for high-precision deep hole drilling, comprising: a U-shaped frame 1; a fixing hole 2 is provided at the top of the U-shaped frame 1; a movable groove 3 is provided at the bottom of the U-shaped frame 1, a U-shaped seat 4 is movably connected in the movable groove 3, an installation hole 6 is provided at the top of the U-shaped seat 4, and a sleeve 7 is installed in the installation hole 6; a spring 5 is fixed at the top of the movable groove 3, and one end of the spring 5 away from the top of the movable groove 3 is fixed to the top of the U-shaped seat 4; a fixing component is provided on the outer wall of the U-shaped seat 4, the fixing component is used to fix the sleeve 7, the fixing component includes a threaded hole 8 opened on the outer wall of the U-shaped seat 4, a threaded rod 10 is threadedly connected in the threaded hole 8, one end of the threaded rod 10 is fixed to a rotating shaft 11, and the other end of the threaded rod 10 is engaged in a locking hole 9 opened on the outer wall of the sleeve 7.

[0032] Specifically, this utility model allows the rotating shaft 11 to drive the threaded rod 10 to move within the threaded hole 8. Once one end of the threaded rod 10 disengages from the locking hole 9, the sleeve 7 can be disassembled. Compared to existing designs, this utility model facilitates the disassembly of the sleeve 7, thereby making it easier to clean the debris inside the sleeve 7, preventing debris from clogging the sleeve 7, and improving the working efficiency of the drill bit.

[0033] Example 2:

[0034] Please see Figure 1-3 This utility model provides a technical solution: an auxiliary device for high-precision deep hole drilling. A perforation 15 is opened at the top of the U-shaped frame 1. A container 16 is installed at the top of the U-shaped frame 1. The container 16 is filled with water and a water pump is installed inside the container 16. A connecting pipe 17 is fixed at the outlet of the water pump, passing through the container 16 and through the perforation 15. A nozzle 18 is installed at one end of the connecting pipe 17. A connecting plate 12 is fixed at the bottom of the U-shaped base 4. An anti-slip pad 13 is installed at the bottom of the connecting plate 12. A fixing ear 14 is fixed on the outer wall of the connecting plate 12.

[0035] Specifically, this utility model activates a water pump, which causes water inside the container 16 to enter the nozzle 18 through the connecting pipe 17 and then spray it onto the drill bit. This achieves two goals: firstly, dust reduction and improved air quality; and secondly, cooling of the drill bit, thereby increasing its working efficiency and lifespan.

[0036] This utility model has a connecting plate 12 fixed at the bottom of the U-shaped seat 4, and an anti-slip pad 13 installed at the bottom of the connecting plate 12. Under the action of the anti-slip pad 13, the sleeve 7 can be prevented from shifting or moving during operation, thereby ensuring the drilling accuracy of the drill bit.

[0037] Furthermore, by fixing the fixing ears 14 to the outer wall of the connecting plate 12, the workers can step on the fixing ears 14 or take appropriate measures to fix the fixing ears 14, which further improves the overall stability and further ensures the drilling accuracy of the drill bit.

[0038] Working principle:

[0039] First, move the entire unit to the designated area, then install the drill bit into the fixed hole 2, and place the U-shaped seat 4 against the workpiece surface. Start the drill bit to perform drilling operations on the workpiece.

[0040] Secondly, by rotating the shaft 11, the shaft 11 drives the threaded rod 10 to move within the threaded hole 8. After one end of the threaded rod 10 disengages from the clasp 9, the sleeve 7 can be disassembled. Compared with the existing ones, this utility model facilitates the disassembly of the sleeve 7, thereby facilitating the cleaning of debris inside the sleeve 7, preventing debris from clogging the sleeve 7, and improving the working efficiency of the drill bit.

[0041] Finally, by starting the water pump, the water inside the container 16 will enter the nozzle 18 through the connecting pipe 17 and be sprayed onto the drill bit by the nozzle 18. On the one hand, this can reduce dust and improve air quality, and on the other hand, it can cool down the drill bit, thereby improving the working efficiency and service life of the drill bit.

[0042] By fixing a connecting plate 12 to the bottom of the U-shaped seat 4, and installing an anti-slip pad 13 at the bottom of the connecting plate 12, the sleeve 7 can be prevented from shifting or moving during operation, thereby ensuring the drilling accuracy of the drill bit.

[0043] Furthermore, by fixing the fixing ears 14 to the outer wall of the connecting plate 12, the workers can step on the fixing ears 14 or take appropriate measures to fix the fixing ears 14, which further improves the overall stability and further ensures the drilling accuracy of the drill bit.
