Description

Technical Field

[0001] The invention relates to the technical field of titanium alloy drilling, and in particular to a novel deep hole drill special for titanium alloy and equipment thereof. Background Art

[0002] Titanium alloy is an alloy composed of titanium and other elements. Titanium has two isomorphous forms: titanium is an allotrope with a melting point of 1668°C. It presents a close-packed hexagonal lattice structure below 882°C, called α-titanium; it presents a body-centered cubic lattice structure above 882°C, called β-titanium. By taking advantage of the different characteristics of the above two structures of titanium, appropriate alloying elements are added to gradually change its phase transition temperature and component content to obtain titanium alloys with different structures.

[0003] Chinese patent publication number CN 217647526 U discloses a titanium alloy deep hole processing device, including a drilling machine body, a motor, a mobile machine and a lifting arm, wherein the motor is arranged above the drilling machine body, the mobile machine is arranged below the right side of the motor, the lifting arm is arranged below the mobile machine, the lifting arm is connected to the mobile machine, the control panel is arranged on the front of the mobile machine, the single chip microcomputer is arranged below the right side of the control panel, the single chip microcomputer is connected to the mobile machine, and the electric drill is arranged below the lifting arm;

[0004] The above-mentioned titanium alloy deep hole processing device uses an electric drill to drill holes in the titanium alloy, and the lifting arm can control the electric drill to move vertically; however, as a deep hole processing device, it is used to drill holes with greater depths as the name suggests. However, the length of the electric drill of the above-mentioned deep hole processing device is obviously shorter, and its electric drill only has the function of drilling holes. When drilling deep holes, firstly, the length of its electric drill cannot meet the needs of drilling deep holes. Secondly, during the drilling process, a large amount of debris will appear in the hole and high temperature will be generated. The above-mentioned electric drill cannot discharge the debris, so the debris accumulates in the hole, which not only affects the normal drilling work, but also causes wear on the inner wall of the titanium alloy and the electric drill. The high temperature generated by the intense friction between the electric drill and the titanium alloy will also affect the normal operation of the electric drill, and may even cause damage to the electric drill.

[0017] The beneficial effects of the present invention are:

[0018] 1. In the present invention, the drill body is arranged so that the drill shank is flat, which is convenient for clamping the drill shank and can prevent the drill body from idling when drilling. The outer sides of the drill rod and the drill bit are provided with interconnected chip grooves. When drilling, the generated debris can be gradually moved out of the hole along the chip grooves, thereby preventing the debris from accumulating in the hole and preventing the debris from having a negative impact on the drilling work. During the drilling process, the coolant continuously flows into the hole from the drill bit through multiple oil holes. The main function of the coolant is to quickly absorb and take away the high temperature generated during drilling to improve the durability of the drill bit. At the same time, the coolant penetrates between the drill bit and the debris to reduce the friction between the drill bit and the chips, which can not only reduce the wear on the drill bit, but also allow the chips to be quickly discharged from the hole.

[0019] 2. In the present invention, through the setting of the bearing component, the titanium alloy rod to be drilled is first placed on the bearing component, and the weight of the titanium alloy rod itself can press the lifting arc plate downward, allowing the lifting arc plate to move downward, and the lifting arc plate drives the two rotating arc plates to move while moving downward, allowing the two rotating arc plates to rotate first with the two connecting shafts 1 as the center of the circle, until the lifting arc plate moves down to be flush with the outer arc plate, at this time, the outer arc plate, the rotating arc plate and the lifting arc plate can cooperate to clamp the titanium alloy rod, while carrying the titanium alloy rod, it can also prevent the titanium alloy rod from rolling, thereby ensuring the stability of the titanium alloy rod; when the lifting arc plate moves downward, the connecting rod and the push plate move downward synchronously until the multiple limit blocks 1 on the push plate move to below the limit block 2, at this time the limit block 2 can block the limit block 1 to prevent the push plate from being displaced, thereby preventing the movable part from loosening when clamping the titanium alloy rod.

[0020] 3. In the present invention, through the setting of the transmission component, after the bearing component fixes the titanium alloy rod, the motor 2 controls the slide to move along the trajectory of the slide rail toward the titanium alloy rod through the screw 2; the slide drives the chuck and the toothed plate assembly to move while moving, and the chuck clamps the titanium alloy rod after moving to the end of the titanium alloy rod, and then the slide continues to move, at which time the toothed plate meshes with the gear and drives the threaded barrel to rotate, and the threaded barrel drives screw 1 to descend when rotating, and screw 1 drives the two clamping assemblies to descend at the same time, and during the process of the clamping assembly descending, the rotating arc plate is forced to rotate and expand outward, and at this time the titanium alloy rod no longer presses the lifting arc plate, and the rotating arc plate will drive the lifting arc plate to rise, finally making the clamping assembly open and closed.

[0021] 4. In the present invention, through the setting of the positioning assembly, the positioning tooth plate is connected with the gear under the action of spring three, and the positioning tooth plate can fix the gear. After the titanium alloy rod is placed on the load-bearing assembly, the positioning tooth plate can prevent the threaded barrel from rotating by fixing the gear, and can prevent the load-bearing assembly from descending before the chuck clamps the titanium alloy rod; after the chuck clamps the titanium alloy rod, the tooth plate is engaged with the gear and at the same time, the pushing block pushes the positioning tooth plate, so that the positioning tooth plate no longer hinders the gear, and the tooth plate can drive the gear to rotate normally.

[0022] 5. In the present invention, through the setting of the drilling assembly, the chuck clamps the end of the titanium alloy rod and moves the titanium alloy rod to the drilling assembly, and the end of the titanium alloy rod away from the chuck first passes through the inner side of the ring until the titanium alloy rod is fitted with the drill body, and then the motor drives the chuck to rotate rapidly, and the chuck also drives the titanium alloy rod to rotate rapidly. While the chuck rotates, the slide will move slowly, allowing the titanium alloy rod to slowly approach the drill body while rotating rapidly, so that the drill body can drill a hole in the titanium alloy rod; the ring plays a role in supporting the titanium alloy rod. When drilling, the ring can ensure the stability of the titanium alloy rod and prevent the titanium alloy rod from tilting or shifting, which can not only make the drilled holes meet the standards, but also prevent the titanium alloy rod from tilting and causing uneven force on the drill body and causing damage.

[0049] like Figure 1 As shown, an embodiment of the present invention discloses a novel deep hole drill specially used for titanium alloy, comprising a drill body 5, wherein the drill body 5 comprises a drill shank 51, wherein the outer side of the drill shank 51 is flat for easy clamping and positioning, and the inner side is provided with a plurality of oil holes 54 penetrating the drill shank 51; a drill rod 52 is fixedly connected to one end of the drill shank 51, wherein the drill rod 52 is made of a seamless steel pipe, and the outer side of the drill rod 52 is provided with a chip groove, and the inner side is provided with a plurality of oil holes 54 penetrating the drill rod 52; a drill bit 53 is fixedly connected to one end of the drill rod 52 away from the drill body 5, wherein the outer side of the drill bit 53 is provided with a chip groove, and the inner side is provided with a plurality of oil holes 54 penetrating the drill bit 53; the chip groove of the drill rod 52 corresponds to the position of the chip groove of the drill bit 53, and the oil hole 54 of the drill shank 51 is connected to the oil holes 54 of the drill rod 52 and the drill bit 53.

[0050] Through the setting of the drill body 5, the drill shank 51 is flat, which is convenient for clamping the drill shank 51 and can prevent the drill body 5 from idling when drilling; the outer sides of the drill rod 52 and the drill bit 53 are provided with interconnected chip grooves. When drilling, the generated debris can gradually move out of the hole along the chip grooves, thereby preventing the debris from accumulating in the hole and preventing the debris from having a negative impact on the drilling work; during the drilling process, the coolant continuously flows into the hole from the drill bit 53 through a plurality of oil holes 54. The main function of the coolant is to quickly absorb and take away the high temperature generated during drilling to improve the durability of the drill bit 53. At the same time, the coolant penetrates between the drill bit 53 and the debris to reduce the friction between the drill bit and the chips, which can not only reduce the wear of the drill bit 53, but also allow the chips to be quickly discharged from the hole.

While the chuck 13 rotates, the slide 11 moves slowly, allowing the titanium alloy rod 6 to slowly approach the drill body 5 while rotating rapidly, so that the drill body 5 punches the titanium alloy rod 6. The ring 33 plays a role in supporting the titanium alloy rod 6. When punching, the ring 33 can ensure the stability of the titanium alloy rod 6 and prevent the titanium alloy rod 6 from tilting or shifting.
