Description

Technical Field

[0001] This utility model relates to the field of fuel tank manufacturing technology, specifically a drilling device for machining fuel tank mounting holes. Background Technology

[0002] In the manufacturing process of fuel tanks, the machining of mounting holes is a crucial step. These mounting holes are not only used to secure the fuel tank itself, but also to ensure accurate connection between the fuel tank and other components (such as fuel lines, sensors, etc.). Therefore, the machining quality of the fuel tank mounting holes directly affects the overall performance and safety of the fuel tank.

[0003] For example, application number CN202022283133.8 discloses a drilling device for machining the end face of an oil tank. The device includes a support mechanism, a drilling mechanism at the upper end of the support mechanism, and a fixing mechanism located on the lower side of the drilling mechanism on the support mechanism. The fixing mechanism, the drilling mechanism, and the support mechanism are connected. The support mechanism includes a base, a column at the upper end of the base, and a top plate at the upper end of the column. The fixing mechanism includes symmetrically arranged fixing plates, a cylinder on one side of each fixing plate, guide columns at both ends of the cylinder, and the piston rod of the cylinder passing through the fixing plates. Through this method, the present application provides a drilling device for machining the end face of an oil tank. This drilling device drives a driven gear and a main shaft to rotate via a main gear, distributing power to multiple drill bits. This causes a hydraulic telescopic column to move the entire device, simultaneously machining the holes on the end face of the oil tank, thus improving drilling efficiency.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can solve the problem that current drilling mainly involves single, sequential drilling operations, resulting in low operating efficiency and impacting production progress, during the large-scale drilling of oil tanks, the drill bit will wear out rapidly due to high temperatures under high-efficiency operation, generating wear particles. This will produce more heat and wear particles, not only reducing drilling efficiency but also reducing the accuracy of hole opening, and even causing damage and losses. Utility Model Content

This device has the advantages of auxiliary cooling and lubrication, solving the problem that when machining large quantities of fuel tank holes, the drill bit will wear out rapidly due to high temperature under high-efficiency operation, resulting in wear particles. This will generate more heat and wear particles, which will not only reduce drilling efficiency but also reduce the accuracy of hole opening and even cause damage and losses.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drilling device for machining fuel tank mounting holes, comprising a worktable, a drilling device, and a clamping device. The bottom rear side of the drilling device is fixedly connected to the top rear side of the worktable. The bottom of the clamping device is fixedly connected to both sides of the front side of the top of the worktable. A support plate is fixedly connected to the top of the worktable. An annular pipe is fixedly connected to the top of the front of the support plate. A universal fuel injection pipe is fixedly connected to the bottom of the annular pipe. Six universal fuel injection pipes are arranged in a ring and evenly distributed. An oil supply assembly is fixedly connected to the right side of the rear side of the top of the worktable. A recovery mechanism is provided on the front side of the top of the worktable.

[0007] In a preferred embodiment of this utility model, the oil supply assembly includes an oil storage tank. The bottom of the oil storage tank is fixedly connected to the right side of the rear side of the top of the workbench. The oil storage tank contains lubricating oil. A circulating water pump is installed on the front of the oil storage tank. The bottom of the circulating water pump is fixedly connected to the right side of the top of the workbench. The input end of the circulating water pump is connected to the oil storage tank through a conduit, and the output end of the circulating water pump is connected to an annular pipe through a conduit.

[0008] As a preferred embodiment of this utility model, the recycling mechanism includes a swivel groove, which is located on the front side of the top of the workbench. A connecting groove is provided on the rear side of the bottom of the inner wall of the swivel groove. A transfer box is fixedly connected to the bottom of the workbench. The transfer box is connected to the swivel groove through the connecting groove. The transfer box is connected to the oil storage tank through a conduit.

[0009] As a preferred embodiment of this invention, a filter plate is provided inside the connecting groove, and the filter plate is located at the top of the connecting groove.

[0010] As a preferred embodiment of this utility model, support blocks are fixedly connected to both sides of the inner wall of the connecting groove, and the bottom sides of the filter plate are movably connected to the top of the support blocks.

[0011] As a preferred embodiment of this invention, a sealing rubber ring is fixedly connected to the surface of the filter plate, and the surface of the sealing rubber ring is slidably connected to the inner wall of the connecting groove.

[0012] As a preferred embodiment of this utility model, a transparent observation window is fixedly embedded on the right side of the oil tank, and a scale groove is provided on the rear side of the right side of the oil tank, with several scale grooves distributed at equal intervals.

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

[0014] 1. This utility model, by setting up a universal oil spray pipe, allows the user to adjust the nozzle of the universal oil spray pipe to align with the opening point of the oil tank installation port before drilling the hole in the oil tank. Then, when the drilling device is started to drill the hole in the oil tank, the oil supply component supplies lubricating oil to the universal oil spray pipe and sprays it onto the drill bit to cool and lubricate it. This solves the problem that when drilling a large number of holes in the oil tank, the drill bit will wear out rapidly due to high temperature under high-efficiency operation, resulting in wear particles. This will generate more heat and wear particles, which will not only reduce drilling efficiency, but also reduce the accuracy of hole opening, and even cause damage and losses. This invention achieves the effect of auxiliary cooling and lubrication.

[0015] 2. This utility model, by setting up an oil supply component, allows the user to spray lubricating oil into the opening of the oil tank mounting hole through the universal oil spray pipe for cooling and lubrication. The circulating water pump is then started, causing the input end of the circulating water pump to draw the lubricating oil in the oil storage tank. The lubricating oil is then transported from the input end to the annular pipe through the conduit, and then flows through the annular pipe into each universal oil spray pipe, finally spraying it onto the opening of the oil tank. This reduces the temperature and friction during the drilling process, improving the service life of the drill bit and the processing quality.

[0016] 3. This utility model, by setting up a recycling device, ensures that during the process of spraying lubricating oil from the oil storage tank into the oil tank mounting hole using a universal oil spray pipe, the lubricating oil that has completed lubrication and cooling will first flow into the groove on the workbench, and then flow into the transfer box through the connecting groove. Subsequently, the transfer box is connected to the oil storage tank through a conduit, so that when the circulating water pump draws lubricating oil from the oil storage tank, the lubricating oil in the transfer box continuously enters the transfer box, ultimately achieving the effect of lubricating oil recycling, thereby reducing the cost of lubricating oil use.

[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] like Figures 1 to 3 As shown, the present invention provides a drilling device 2 for machining fuel tank mounting holes, including a workbench 1, a drilling device 2, and a clamping device 3. The bottom rear side of the drilling device 2 is fixedly connected to the top rear side of the workbench 1. The bottom of the clamping device 3 is fixedly connected to both sides of the top front side of the workbench 1. A support plate 4 is fixedly connected to the top of the workbench 1. An annular pipe 5 is fixedly connected to the top of the front of the support plate 4. A universal fuel injection pipe 6 is fixedly connected to the bottom of the annular pipe 5. Six universal fuel injection pipes 6 are arranged in a ring and are evenly distributed. An oil supply assembly 7 is fixedly connected to the right side of the rear side of the top of the workbench 1. A recovery mechanism 8 is provided on the front side of the top of the workbench 1.

[0023] refer to Figure 1 The oil supply assembly 7 includes an oil storage tank 71. The bottom of the oil storage tank 71 is fixedly connected to the right side of the rear side of the top of the workbench 1. The oil storage tank 71 is filled with lubricating oil. A circulating water pump 72 is installed on the front of the oil storage tank 71. The bottom of the circulating water pump 72 is fixedly connected to the right side of the top of the workbench 1. The input end of the circulating water pump 72 is connected to the oil storage tank 71 through a conduit. The output end of the circulating water pump 72 is connected to the annular pipe 5 through a conduit.

[0024] As a technical optimization of this utility model, by setting up the oil supply component 7, when the user needs the universal oil spray pipe 6 to spray lubricating oil into the opening of the oil tank mounting hole for cooling and lubrication, the circulating water pump 72 is started, so that the input end of the circulating water pump 72 draws the lubricating oil in the oil storage tank 71, and then delivers it from the input end to the annular pipe 5 through the conduit. Then the lubricating oil flows into each universal oil spray pipe 6 through the annular pipe 5, and finally sprays it onto the opening of the oil tank, thereby reducing the temperature and friction during the drilling process and improving the service life of the drill bit and the processing quality.

[0025] refer to Figure 1 and Figure 2 The recycling mechanism 8 includes a swivel groove 81, which is located on the front side of the top of the workbench 1. A connecting groove 82 is provided on the rear side of the bottom of the inner wall of the swivel groove 81. A transfer box 83 is fixedly connected to the bottom of the workbench 1. The transfer box 83 is connected to the swivel groove 81 through the connecting groove 82. The transfer box 83 is connected to the oil storage tank 71 through a conduit.

[0026] As a technical optimization of this utility model, by setting up a recycling device, during the process of using the universal oil spray pipe 6 to spray lubricating oil from the oil storage tank 71 to the opening of the oil tank mounting hole, the lubricating oil that has completed lubrication and cooling will first flow into the groove 81 on the workbench 1, and then flow into the transfer box 83 through the connecting groove 82. Subsequently, by using the connection between the transfer box 83 and the oil storage tank 71 through the conduit, when the circulating water pump 72 draws lubricating oil from the oil storage tank 71, the lubricating oil in the transfer box 83 will continuously enter the transfer box 83, ultimately achieving the effect of lubricating oil recycling, thereby reducing the cost of lubricating oil use.

[0027] refer to Figure 3 A filter plate 9 is provided inside the connecting groove 82, and the filter plate 9 is located at the top of the connecting groove 82.

[0028] As a technical optimization of this utility model, by setting up a filter plate 9, the lubricating oil in the groove 81 flows into the transfer box 83 through the connecting groove 82. The lubricating oil is filtered by the filter plate 9, removing impurities such as oil tank drilling debris, and then enters the transfer box 83, maintaining the cleanliness of the lubricating oil, thereby extending the service life of the lubricating oil and reducing the wear on the drilling device 2 and the oil tank.

[0029] refer to Figure 3 Both sides of the inner wall of the connecting groove 82 are fixedly connected to the support blocks 10, and the two sides of the bottom of the filter plate 9 are movably connected to the top of the support blocks 10.

[0030] As a technical optimization of this utility model, by setting a support block 10, the filter plate 9 will be supported by the support block 10 during the process of placing it into the connecting groove 82, so that the filter plate 9 can remain stable when it is impacted by lubricating oil and drill cuttings, and effectively filter out the impurities therein, thereby preventing the filter plate 9 from falling into the transfer box 83 along the connecting groove 82, thus improving the stability of the filter plate 9 when filtering lubricating oil.

[0031] refer to Figure 3 A sealing rubber ring 11 is fixedly connected to the surface of the filter plate 9, and the surface of the sealing rubber ring 11 is slidably connected to the inner wall of the connecting groove 82.

[0032] As a technical optimization of this utility model, by setting a sealing rubber ring 11, when the filter plate 9 is placed into the connecting groove 82, the sealing rubber ring 11 will replace the direct contact between the filter plate 9 and the connecting groove 82, and will be deformed by compression, thereby increasing the contact area between the filter plate 9 and the connecting groove 82, so that the filter plate 9 and the connecting groove 82 are tightly fitted, thereby preventing unfiltered lubricating oil from flowing directly into the transfer box 83 from the gap between the filter plate 9 and the connecting groove 82, reducing the purity of the lubricating oil in the transfer box 83.

[0033] refer to Figure 2 A transparent observation window 12 is fixedly embedded on the right side of the oil tank 71. A scale groove 13 is provided on the rear side of the right side of the oil tank 71. Several scale grooves 13 are provided and are distributed at equal intervals.

[0034] As a technical optimization of this utility model, by setting a transparent observation window 12 and a scale groove 13, during the daily circulation of lubricating oil, the user can observe the remaining amount and quality of lubricating oil in the oil tank 71 by observing the transparent observation window 12 and the scale, so as to make it convenient to replenish or replace the lubricating oil in time when it is insufficient or its quality deteriorates, thereby improving the user's work efficiency.

[0035] The working principle and usage process of this utility model are as follows: When it is necessary to drill an installation hole in the oil tank, the user first places the oil tank on the front side of the top of the workbench 1, then activates the clamping device 3 to clamp and fix the oil tank, and then adjusts the nozzle of the universal spray pipe 6 to align with the opening point of the oil tank installation port. At this time, the circulating water pump 72 can be started, so that the input end of the circulating water pump 72 draws the lubricating oil in the oil storage tank 71, and then delivers it from the input end through the conduit into the annular pipe 5. Then the lubricating oil flows through the annular pipe 5 into each universal spray pipe 6, and finally sprays it towards the opening point of the oil tank installation hole. Then the drilling device 2 can be started to descend and drill the installation hole in the oil tank. As a result, the lubricating oil is continuously sprayed onto the drilling point. The drill bit and oil tank opening of the 2 are cooled and lubricated. The lubricating oil that has been cooled and lubricated will first flow into the groove 81 on the worktable 1, and then flow into the connecting groove 82. It will be filtered by the filter plate 9 in the connecting groove 82 to remove impurities such as oil tank drilling debris. Finally, it will flow into the transfer box 83. Then, the transfer box 83 is connected to the oil storage tank 71 through the conduit. When the circulating water pump 72 draws lubricating oil from the oil storage tank 71, the lubricating oil in the transfer box 83 will continuously enter the transfer box 83. In the end, the lubricating oil is recycled and reused, continuously cooling the drilling site, stabilizing the temperature of the drill bit of the drilling device 2 and the accuracy of the oil tank installation hole, thus having the advantages of auxiliary cooling and lubrication.

[0036] In summary, this drilling device for machining fuel tank mounting holes, by incorporating a universal oil spray pipe 6, allows the user to pre-align the nozzle of the universal oil spray pipe 6 with the drilling point of the fuel tank mounting opening when a mounting hole needs to be drilled. Then, when the drilling device 2 is started to drill the hole, the oil supply component 7 supplies lubricating oil to the universal oil spray pipe 6, spraying it onto the drill bit for cooling and lubrication. This solves the problem that during large-scale drilling of fuel tanks, the drill bit would wear rapidly due to high temperatures under high-efficiency operation, generating wear particles. This would lead to more heat and wear particles, reducing drilling efficiency, decreasing hole accuracy, and even causing damage and losses.
