Abstract
Description
Technical Field
[0001] This utility model relates to the field of drilling device technology, specifically a drilling device for rapid positioning of stainless steel pipe processing. Background Technology
[0002] In the field of stainless steel pipe processing, drilling is a common and crucial process, especially for scenarios requiring rapid positioning and drilling, such as pipe fitting processing and furniture bracket manufacturing. Efficient and precise drilling devices are essential for improving production efficiency. Currently, rapid positioning drilling devices for stainless steel pipe processing have been applied to some extent. These devices use positioning components (such as clamps and limit blocks) to quickly fix the pipe material, and then work with a drilling mechanism to complete the drilling operation. This meets the efficiency requirements of mass production to a certain extent. However, an existing rapid positioning drilling device for stainless steel pipe processing (announcement number: CN215587891U) has the following disadvantages in use: During the drilling process of stainless steel pipes, a large amount of metal debris is generated. These debris are easily splashed and scattered to various parts of the workbench due to the impact and rotational forces during drilling, affecting the cleanliness of the workbench and requiring frequent cleaning by staff. However, due to the presence of many devices on the workbench, cleaning is inconvenient. Therefore, this patent proposes a drilling device for processing stainless steel pipes with rapid positioning to solve the above problems. Utility Model Content
[0003] The purpose of this invention is to provide a drilling device for rapid positioning of stainless steel pipes, so as to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a drilling device for rapid positioning of stainless steel pipes, comprising a worktable, a support frame fixed at the top of the worktable, a collection trough at the top of the worktable, a bearing rod fixed inside the collection trough, a support and protective frame inserted into the collection trough, the support and protective frame being located above the bearing rod, an inclined filter screen fixed inside the support and protective frame, a liquid storage tank fixed at the top of the worktable, a delivery pump installed inside the liquid storage tank, a connecting pipe fixedly connected to the outlet of the delivery pump, a cooling pipe fixedly connected to the bottom end of the connecting pipe, a water pump installed in the collection trough, a fixing frame fixed at the top of the worktable, a delivery pipe fixedly connected to the side of the fixing frame near the cooling pipe, multiple nozzles fixedly connected to one side of the delivery pipe, a fixing pipe fixedly connected to the outlet of the water pump, and the fixing pipe passing through the worktable and fixedly connected to the delivery pipe.
[0005] Preferably, a railing is fixed inside the collection trough, and a support and protective frame is located between the collection trough and the railing.
[0006] Preferably, two first cylinders are fixed to the inner wall of the top of the support frame, and upper clamping plates are fixed to the output ends of the two first cylinders. Two lower clamping plates are fixed to the top of the worktable, and the two lower clamping plates are located directly below the two upper clamping plates. Insertion rods are fixed to the bottom ends of the upper clamping plates and are inserted into the lower clamping plates.
[0007] Preferably, a second cylinder is fixed to the inner wall of the top of the support frame. The second cylinder is located between the two first cylinders and directly above the collection tank. A mounting bracket is fixed to the output end of the second cylinder. A drill bit is rotatably connected to the bottom end of the mounting bracket. A motor is fixed inside the mounting bracket. The output end of the motor passes through the mounting bracket and is fixed to the drill bit.
[0008] Preferably, a drain pipe is fixed to one side of the workbench, with one end of the drain pipe located in the collection tank and the other end passing through the workbench and fitted with a valve.
[0009] Preferably, a controller is installed on the side of the support frame away from the liquid storage tank, and the controller is electrically connected to the first cylinder, the second cylinder, the delivery pump, the water pump and the motor.
[0010] Compared with the prior art, the beneficial effects of this utility model are: By activating the delivery pump, coolant from the storage tank is delivered to the connecting pipe. The coolant then flows out through the cooling pipe to cool the drilling site and flush away drilling debris, which falls into the collection tank. The coolant is then filtered through a filter screen, while debris remains on top of the screen. The collection tank also stores some coolant. A water pump delivers the filtered coolant and the remaining coolant from the collection tank through a fixed pipe to the delivery pipe, where it is sprayed out through nozzles to suppress dust. This allows fine particles generated during drilling to be adsorbed and filtered onto the filter screen. The filter screen is tilted to facilitate the automatic sliding of debris, reducing its accumulation on the screen surface, slowing down clogging, extending the cleaning cycle, and preventing debris from splattering across the work surface and affecting later cleaning. Furthermore, when cleaning is needed, simply move the support frame upwards so the railing no longer obstructs it, then pull the support frame outwards to clean the filter screen – a very convenient process.

[0013] 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.
[0014] In the stainless steel pipe processing industry, drilling is a common and crucial process, especially for scenarios requiring rapid positioning and drilling, such as pipe fitting processing and furniture frame manufacturing. Efficient and precise drilling devices are essential for improving production efficiency. Currently, rapid positioning and drilling devices for stainless steel pipe processing have been applied to some extent. These devices use positioning components (such as clamps and limit blocks) to quickly fix the pipe material, and then work in conjunction with a drilling mechanism to complete the drilling operation, thus meeting the efficiency requirements of mass production to a certain extent.
[0015] like Figures 1-4 As shown, this utility model provides a technical solution: a drilling device for rapid positioning of stainless steel pipe processing, including a workbench 1, a support frame 2 fixed at the top of the workbench 1, a collection trough 10 opened at the top of the workbench 1, a bearing rod 13 fixed inside the collection trough 10, a support and protective frame 11 inserted into the collection trough 10, the support and protective frame 11 being located above the bearing rod 13, an inclined filter screen 12 fixed inside the support and protective frame 11, a liquid storage tank 18 fixed at the top of the workbench 1, a delivery pump installed inside the liquid storage tank 18, a connecting pipe 19 fixedly connected to the outlet of the delivery pump, a cooling pipe 20 fixedly connected to the bottom end of the connecting pipe 19, a water pump 14 installed in the collection trough 10, a fixing frame 15 fixed at the top of the workbench 1, a delivery pipe 16 fixedly fixed to the side of the fixing frame 15 near the cooling pipe 20, a plurality of nozzles 17 fixedly connected to one side of the delivery pipe 16, a fixing pipe fixedly connected to the outlet of the water pump 14, the fixing pipe passing through the workbench 1 and fixedly connected to the delivery pipe 16. A railing 21 is fixed inside the collection tank 10, and a support and protective frame 11 is located between the collection tank 10 and the railing 21.
[0016] It is important to note that by starting the delivery pump, the coolant in the storage tank 18 is delivered to the connecting pipe 19, and then flows out through the cooling pipe 20 to cool the drilling location and wash away the debris generated during drilling. The debris falls into the collection tank 10 and is filtered by the filter screen 12. The debris remains on the top of the filter screen 12. In addition, the collection tank 10 stores some coolant. The water pump 14 delivers the filtered coolant and the portion stored in the collection tank 10 through the fixed pipe to the delivery pipe 16, and then sprays it out through the nozzle 17 to suppress dust. This allows the fine particles generated during drilling to be adsorbed and fall onto the filter screen 12 for filtration. The filter screen 12 is set in an inclined state, which can promote the automatic sliding of debris, reduce the accumulation of debris on the screen surface, slow down the clogging of the filter screen, extend the cleaning cycle, and prevent debris from splashing to various parts of the table during drilling, which would affect subsequent cleaning. In addition, when cleaning is required, simply move the support frame 11 upward so that the railing 21 no longer obstructs the support frame 11, and then pull the support frame 11 outward to clean the filter screen 12, which is quite convenient.
[0017] like Figure 2 As shown, two first cylinders 3 are fixed to the inner wall of the top of the support frame 2. The output ends of the two first cylinders 3 are fixed with upper clamping plates 4. Two lower clamping plates 5 are fixed to the top of the worktable 1. The two lower clamping plates 5 are located directly below the two upper clamping plates 4. The bottom end of the upper clamping plate 4 is fixed with a plug rod 6, which is inserted into the lower clamping plate 5.
[0018] It should be noted that by activating the first cylinder 3, the first cylinder 3 drives the upper clamping plate 4 to move downward, so that the stainless steel pipe is clamped between the upper clamping plate 4 and the lower clamping plate 5, which facilitates the subsequent drilling of the stainless steel pipe.
[0019] like Figure 2 and Figure 3 As shown, a second cylinder 7 is fixed to the inner wall of the top of the support frame 2. The second cylinder 7 is located between the two first cylinders 3 and directly above the collection tank 10. An installation frame 8 is fixed to the output end of the second cylinder 7. A drill bit 9 is rotatably connected to the bottom end of the installation frame 8. A motor is fixed inside the installation frame 8. The output end of the motor passes through the installation frame 8 and is fixed to the drill bit 9.
[0020] It should be noted that by starting the second cylinder 7, the second cylinder 7 drives the drill bit 9 to move downward, and by starting the motor, the motor drives the drill bit 9 to rotate and drill a hole in the stainless steel pipe.
[0021] like Figure 3 As shown, a drain pipe is fixed on one side of the workbench 1. One end of the drain pipe is located in the collection tank 10, and the other end passes through the workbench 1 and is fitted with a valve.
[0022] It should be noted that when it is necessary to remove the coolant from the collection tank 10, the valve can be opened to allow the coolant to drain through the drain pipe.
[0023] like Figure 1 As shown, a controller is installed on the side of the support frame 2 away from the liquid storage tank 18. The controller is electrically connected to the first cylinder 3, the second cylinder 7, the delivery pump, the water pump 14 and the motor.
[0024] It should be noted that the electrical components in this solution are controlled by their associated peripheral controllers, and the control circuit can be implemented by simple programming by those skilled in the art. This is common knowledge in the field, and we are only using it without making any improvements. Furthermore, since this utility model is mainly used to protect mechanical devices, we will not explain the control method and circuit connection in detail.
[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
