Description

Technical Field

[0001] This utility model relates to the technical field of coolant supply devices, specifically a coolant supply device for deep hole drilling of aircraft titanium alloy components. Background Technology

[0002] The deep hole drilling coolant supply device for aircraft titanium alloy components is a specialized high-pressure, high-flow-rate coolant delivery system. Its core function is to continuously and stably inject sufficient coolant into the cutting area during deep hole drilling. Typically, the coolant is sprayed directly onto the cutting edge and cutting contact surface through a special channel inside the drill bit. This device is crucial for titanium alloy machining because titanium alloys have poor thermal conductivity, are prone to high temperatures and tool sticking, and require efficient cooling and lubrication to prevent excessive tool wear, workpiece thermal damage, reduce cutting forces, and facilitate chip removal.

[0003] However, in existing coolant supply devices, the connection between the coolant supply pipe and the supply pump lacks reinforcement, and the interface may deform, loosen, or fail to seal under accidental pulling or impact, affecting its service life. Therefore, those skilled in the art have provided a coolant supply device for deep hole drilling of aircraft titanium alloy components to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a coolant supply device for deep hole drilling of aircraft titanium alloy components, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A deep hole drilling coolant supply device for aircraft titanium alloy components includes a mounting housing, a mounting base fixed to the bottom of the mounting housing, a connecting base mounted on the top of the mounting housing, a filter screen plate provided on the top of the mounting housing, a supply pump mounted on the top of the connecting base, a coolant supply pipe connected to the outside of the supply pump, a reinforcement mechanism provided on the outside of the supply pump, and a stabilizing mechanism provided on the top of the connecting base.

[0007] The reinforcement mechanism includes a lower reinforcement sleeve, the top of which is hinged to an upper reinforcement sleeve. Protective sleeves are fixed to the inner walls of both the lower and upper reinforcement sleeves. A lower mounting pad is fixed to the outer side of the lower reinforcement sleeve, and an upper mounting sleeve is fixed to the outer side of the upper reinforcement sleeve. A fixing sleeve is fixed to the top of the lower mounting pad. A fixing threaded post is installed on the top of the fixing sleeve. A washer is movably sleeved on the outer side of the fixing threaded post, and a metal threaded sleeve is threadedly connected to the outer side of the fixing threaded post.

[0008] As a further embodiment of this utility model: the stabilizing mechanism includes a fixing pad, a fixing semi-threaded column fixed to the top of the fixing pad, a metal block fixed to the top of the connecting seat, a metal column fixed to the top of the metal block, a limiting pad fixed to the outside of the metal column, and a reinforcing plate connected to the outside of the metal column via a bearing.

[0009] As a further embodiment of this utility model: a movable semi-threaded post is installed on the top of the reinforcing plate, and the outer sides of the movable semi-threaded post and the fixed semi-threaded post are connected by a connecting threaded sleeve.

[0010] As a further embodiment of this utility model: the fixing pad and the supply pump are fixedly connected, and the bottom surface of the reinforcing plate is in contact with the fixing pad.

[0011] As a further improvement of this utility model: the lower reinforcing sleeve and the supply pump are fixedly connected, and the inner wall of the protective sleeve is in contact with the coolant supply pipe.

[0012] As a further embodiment of this utility model: the upper mounting sleeve is movably sleeved on the outside of the fixed threaded column, and the lower bottom surface of the gasket is in contact with the upper mounting sleeve.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This device is equipped with a reinforcement mechanism, which facilitates the fixing of the upper and lower reinforcement sleeves. This allows the protective sleeves on the inner walls of the upper and lower reinforcement sleeves to fit snugly against the outer side of the coolant supply pipe, significantly enhancing the mechanical strength of the connection. This prevents the coolant supply pipe and supply pump from deforming, loosening, or failing to seal under accidental pulling or collision, effectively suppressing fretting wear and stress concentration at the connection points, reducing the risk of metal fatigue, extending the service life of the pipeline, and ensuring the normal supply of coolant.

[0015] 2. With the stabilizing mechanism, after the supply pump and the connecting seat are fixedly connected, the fixing pad and the connecting seat can be easily fixed, which can strengthen the connection between the supply pump and the connecting seat and ensure the stable assembly of the supply pump.

[0021] 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.

[0022] Please see Figure 1-4 In this embodiment of the present invention, a deep hole drilling coolant supply device for aircraft titanium alloy components includes a mounting housing 1, a mounting base 2 fixed at the bottom of the mounting housing 1, a connecting base 3 mounted at the top of the mounting housing 1, a filter screen plate 4 provided at the top of the mounting housing 1, a supply pump 5 mounted at the top of the connecting base 3, a coolant supply pipe 6 connected to the outside of the supply pump 5, a reinforcing mechanism 7 provided on the outside of the supply pump 5, and a stabilizing mechanism 8 provided at the top of the connecting base 3.

[0023] The reinforcement mechanism 7 includes a lower reinforcement sleeve 71, an upper reinforcement sleeve 72 hinged to the top of the lower reinforcement sleeve 71, protective sleeves 73 fixed to the inner walls of both the lower reinforcement sleeve 71 and the upper reinforcement sleeve 72, a lower mounting pad 74 fixed to the outer side of the lower reinforcement sleeve 71, an upper mounting sleeve 77 fixed to the outer side of the upper reinforcement sleeve 72, a fixing sleeve 75 fixed to the top of the lower mounting pad 74, a fixing threaded post 76 mounted on the top of the fixing sleeve 75, a gasket 78 movably sleeved to the outer side of the fixing threaded post 76, and a metal threaded sleeve 79 threadedly connected to the outer side of the fixing threaded post 76. The lower reinforcement sleeve 71 is fixedly connected to the supply pump 5, the inner wall of the protective sleeve 73 is in contact with the coolant supply pipe 6, the upper mounting sleeve 77 is movably sleeved to the outer side of the fixing threaded post 76, and the lower bottom surface of the gasket 78 is in contact with the upper mounting sleeve 77.

[0024] In one embodiment of this utility model, the stabilizing mechanism 8 includes a fixing pad 81, a fixing semi-threaded column 82 fixed to the top of the fixing pad 81, a metal block 83 fixed to the top of the connecting seat 3, a metal column 84 fixed to the top of the metal block 83, a limiting pad 85 fixed to the outside of the metal column 84, a reinforcing plate 86 connected to the outside of the metal column 84 via a bearing, a movable semi-threaded column 87 installed on the top of the reinforcing plate 86, a connecting threaded sleeve 88 threadedly connected to the outside of the movable semi-threaded column 87 and the fixing semi-threaded column 82, the fixing pad 81 and the supply pump 5 are fixedly connected, and the bottom surface of the reinforcing plate 86 is in contact with the fixing pad 81.

[0025] The working principle of this utility model is as follows: This device is equipped with a reinforcement mechanism 7. After the coolant supply pipe 6 and the supply pump 5 are connected, the upper reinforcement sleeve 72 at the top of the lower reinforcement sleeve 71 can be moved to allow the upper mounting sleeve 77 on the outside of the upper reinforcement sleeve 72 to be movably fitted onto the outside of the fixed threaded post 76. Then, the gasket 78 is movably fitted onto the outside of the fixed threaded post 76, and a metal threaded sleeve 79 is threadedly connected to the fixed threaded post 76. This facilitates the fixation between the upper reinforcement sleeve 72 and the lower reinforcement sleeve 71, allowing the protective sleeve 73 on the inner wall of the upper reinforcement sleeve 72 and the lower reinforcement sleeve 71 to fit against the outside of the coolant supply pipe 6. This significantly enhances the mechanical strength of the connection, preventing the coolant supply pipe 6 and the supply pump 5 from deforming, loosening, or failing to seal under accidental pulling or collision, effectively suppressing the connection part. This reduces fretting wear and stress concentration, lowers the risk of metal fatigue, extends pipeline service life, and helps ensure normal coolant supply. With a stabilizing mechanism 8, after the supply pump 5 and connecting seat 3 are fixedly connected, the corresponding surface of the fixing pad 81 on the outside of the supply pump 5 fits into the connecting seat 3. Then, the reinforcing plate 86 on the outside of the metal column 84 is moved, causing the corresponding surfaces of the movable semi-threaded column 87 and the fixed semi-threaded column 82 on the top of the reinforcing plate 86 to fit together, forming a complete threaded column. Then, the connecting threaded sleeve 88 is used to thread the fixed semi-threaded column 82 and the movable semi-threaded column 87, conveniently completing the fixation between the fixing pad 81 and the connecting seat 3. This reinforces the connection between the supply pump 5 and the connecting seat 3, ensuring stable assembly of the supply pump 5.

[0026] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
