Description

Technical Field

[0001] The utility model relates to a deep hole drill, in particular to a five-axis horizontal deep hole drill mechanism, belonging to the technical field of deep hole drills. Background Technique

[0002] A deep hole drill is a drill bit specifically used for processing deep holes, which can be divided into two categories: external chip removal and internal chip removal. The biggest disadvantages of deep hole drilling are heat dissipation and chip removal difficulties, and due to the slender drill pipe with poor rigidity, it is easy to bend and vibrate. Generally, a pressure cooling system is required to solve the problems of cooling and chip removal. The drill rod of the deep hole drill is slender and has poor rigidity. Since the tool cuts inside the hole, the cutting condition and tool wear cannot be observed;

[0003] Chinese Patent Publication (CN201821902791.7) discloses a five-axis drilling and milling deep hole drill, which uses a cooling channel arranged inside the bearing layer in combination with a high-pressure cooling atomizer installed at the top of the air duct. The liquid is compressed and transformed into a mist and injected into the cooling channel through the air duct, so as to facilitate reducing the surface temperature of the linkage shaft. However, when the existing deep hole drill is in use, due to the lack of a collection structure for debris and cutting fluid, it is easy for the debris and cutting fluid to splash due to the high-speed rotation of the drill bit when discharging the debris and cutting fluid, making it difficult to collect and clean them;

[0004] To solve the above technical problems, a five-axis horizontal deep hole drill mechanism is proposed. Content of the Utility Model

[0005] In view of this, the utility model provides a five-axis horizontal deep hole drill mechanism to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial choice.

[0006] The technical solution of the utility model is realized as follows: A five-axis horizontal deep hole drill mechanism includes a main body mechanism and a collection mechanism;

A driving motor is installed on one side of the mounting shell. The output shaft of the driving motor is connected to the connecting shaft through a coupling;

[0008] The collection mechanism includes a collection cylinder and a fixing plate. The fixing plate is fixedly connected to one end of the collection cylinder. A discharge hole is integrally formed on one side of the collection cylinder. Four sleeves are fixedly connected to one side of the mounting shell at equal intervals. A fixing rod is slidably connected inside the sleeve. One end of the fixing rod is fixedly connected to the fixing plate. A limiting member is fixedly connected to the end of the fixing rod located inside the sleeve. One side of the limiting member is fixedly connected to a spring. One end of the spring is fixedly connected to the sleeve.

[0009] Further preferably, a guide sleeve is sleeved on one side of the connecting shaft, and one side of the guide sleeve is fixedly connected to the mounting shell.

[0010] Further preferably, a first heat dissipation hole is equidistantly distributed on one side of the guide sleeve, and a second heat dissipation hole is equidistantly distributed on both sides of the mounting shell.

[0011] Further preferably, a bracket is fixedly connected to one side of the mounting shell, and the bracket is engaged with the driving motor.

[0012] Further preferably, fixing frames are symmetrically and fixedly connected to one side of the mounting shell, a buffer pad is fixedly connected to one side of the fixing frame, and fixing holes are symmetrically formed on one side of the fixing frame.

As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present utility model. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0025] The embodiments of the present utility model will be described in detail below with reference to the drawings.

[0026] As Figures 1-4 shown, the embodiment of the present utility model provides a five-axis horizontal deep hole drilling mechanism, which is composed of a main body mechanism 10 and a collection mechanism 20.

[0027] The main body mechanism 10 includes a connecting shaft 11, a deep hole drill bit 15 and a mounting shell 12. Bearings 14 are symmetrically installed inside the mounting shell 12. The connecting shaft 11 is fixedly connected to the inner ring of the bearing 14. The connecting shaft 11 is rotatably installed inside the mounting shell 12 through the bearing 14. The deep hole drill bit 15 is installed at one end of the connecting shaft 11. An injection hole 17 is opened inside the deep hole drill bit 15 to facilitate the injection of cutting fluid. A discharge groove 16 is integrally formed on one side of the deep hole drill bit 15, so that the cutting fluid and the chips are discharged from the workpiece together through the discharge groove 16. A driving motor 13 is installed on one side of the mounting shell 12. The output shaft of the driving motor 13 is connected to the connecting shaft 11 through a coupling. A bracket 35 is clamped on one side of the driving motor 13. One side of the bracket 35 is fixedly connected to the mounting shell 12 to enhance the stability of the driving motor 13 through the bracket 35.

[0028] In one embodiment, a guide sleeve 18 for straightening the connecting shaft 11 is sleeved on one side of the connecting shaft 11. One side of the guide sleeve 18 is fixedly connected to the mounting shell 12. In order to facilitate the heat dissipation of the connecting shaft 11, first heat dissipation holes 19 are equidistantly distributed on one side of the guide sleeve 18, and second heat dissipation holes 31 are equidistantly distributed on both sides of the mounting shell 12.

[0029] In one embodiment, in order to facilitate the installation and fixation of the mounting shell 12, fixing brackets 32 are symmetrically and fixedly connected to one side of the mounting shell 12. A buffer pad 33 is fixedly connected to one side of the fixing bracket 32. The buffer pad 33 reduces the impact caused by vibration on the mounting shell 12. Fixing holes 34 are symmetrically formed on one side of the fixing bracket 32.

[0030] The collection mechanism 20 includes a collection cylinder 21, a fixing plate 23 and fixing rods 24. The fixing plate 23 is fixedly connected to one end of the collection cylinder 21. A discharge hole 22 is integrally formed on one side of the collection cylinder 21. Debris and cutting fluid are discharged through the discharge hole 22. Four sleeves 25 are equidistantly and fixedly connected to one side of the mounting shell 12. Four fixing rods 24 are equidistantly and fixedly connected to one side of the fixing plate 23, and one end of the fixing rod 24 penetrates through the sleeve 25. A limiting member 26 is fixedly connected to the end of the fixing rod 24 located inside the sleeve 25. A spring 27 is fixedly connected to one side of the limiting member 26. One end of the spring 27 is fixedly connected to the sleeve 25, so that the spring 27 pushes the limiting member 26 and the fixing rod 24, and makes the collection cylinder 21 always contact the workpiece opening surface.

[0031] When the present utility model works: The mounting shell 12 is installed at a designated position through the fixing bracket 32 in cooperation with the fixing holes 34, and the cutting fluid supply device is connected to the connecting shaft 11, so that the cutting fluid enters the injection hole 17 of the deep hole drill 15 through the connecting shaft 11. The driving motor 13 drives the connecting shaft 11 to rotate, and the connecting shaft 11 drives the deep hole drill 15 to rotate. The deep hole drill 15 is driven by a driving device to drill into the workpiece. At this time, the collection cylinder 21 contacts the opening surface of the workpiece to perform opening on the workpiece. During opening, the cutting fluid is injected into the opening through the injection hole 17, and the debris in the hole and the residual cutting fluid are discharged together from the discharge groove 16. As the deep hole drill 15 penetrates deeper, the collection cylinder 21 always contacts the workpiece opening surface, so that the fixing rod 24 cooperates with the limiting member 26 to squeeze the spring 27, shortening the length of the fixing rod 24 located outside the sleeve 25, so that the collection cylinder 21 shields and collects the discharged debris and cutting fluid, and the debris and cutting fluid are discharged through the discharge hole 22.

[0032] The above are only specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various changes or substitutions thereof, and these should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims described above.
