Description

Technical Field

[0001] This utility model relates to the field of flange drilling technology, and more specifically, to a flange drilling device. Background Technology

[0002] A flange, also called a flange plate or flange, is a part used to connect shafts to each other. It is used for connecting pipe ends and is also used on equipment inlets and outlets for connecting two pieces of equipment. Currently, bolt holes need to be made around the circumference of the flange surface for subsequent docking and fixing. These bolt holes are generally machined using drilling equipment.

[0003] Announcement No. CN217452221U proposes a drilling device for flange processing. This device can automatically process bolt holes on flanges, but it can only drill one bolt hole at a time, thus the drilling efficiency needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a flange drilling processing device.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A flange drilling apparatus includes a processing table, a rotating roller, a gear transmission assembly, a turntable, a fixing component, a mounting table, a telescopic component, a disc, a drive motor, and a drill bit.

[0007] The rotating roller is rotatably connected to the inside of the processing table;

[0008] The gear transmission assembly is fixed on the machining table and connected to the rotating roller;

[0009] One end of the turntable is welded to the rotating roller, and several fasteners with automatic clamping flanges are fixed on the circumference of the turntable;

[0010] The mounting platform is fixedly mounted on the processing table, and the mounting platform is also fixedly equipped with telescopic components.

[0011] The disc is connected to a telescopic component and several synchronously operating drive motors are fixed on the circumference of the disc.

[0012] The drill bit and the drive motor are connected one-to-one.

[0013] Furthermore, a frustum is fixed on the mounting platform, and a collection box is placed on one side of the frustum. Four limiting rollers that contact the outer wall of the flange are fixed on the circumference of the frustum.

[0014] In the above scheme, flanges that have not been drilled will be neatly stacked and placed in contact with the four limiting rollers within the area enclosed by the limiting rollers, thus preventing them from piling up haphazardly.

[0015] Furthermore, a six-degree-of-freedom robotic arm is fixedly mounted on the mounting platform. The six-degree-of-freedom robotic arm is connected to a mounting rod, and an electromagnet is fixedly mounted on the mounting rod. An mounting groove is opened on the processing platform, and an electric push rod is installed in the mounting groove. The retraction rod of the electric push rod passes through the truncated cone and is connected to a push plate that contacts the limiting roller.

[0016] The above solution can automatically complete the unloading of the flange after processing and the secondary loading of the new flange, thereby reducing the labor intensity of manual disassembly and transfer of the flange. That is, the staff only needs to operate on the controller side.

[0017] Furthermore, a collection frame is placed on the processing table below the fixing component.

[0018] Furthermore, the collection frame is symmetrically equipped with slide rails, one end of which is fixed with a limiting plate and a filter element is fitted on the slide rail.

[0019] Furthermore, the filter element is symmetrically provided with lifting rods.

[0020] The above solution uses a collection frame to collect the spray water and some debris that falls during the drilling process. At the same time, the filter can separate the debris from the waste liquid. The waste liquid can then be reused after subsequent processing. The filter screen only needs to be removed and cleaned periodically. The operation is simple and convenient.

[0021] Furthermore, the fastener is a hydraulic chuck.

[0022] Furthermore, the mounting platform is equipped with spray cooling components that are spaced apart from the fixing components and the drill bit.

[0023] The above solution can effectively cool the surface of the flange and the drill bit by spraying water during the drilling process.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] Compared to existing technologies, the flange positioning process in this device is more convenient. After multiple flanges are loaded and positioned, they can be drilled automatically in sequence. During the drilling switching process, the movement positions of several hydraulic chucks are accurate, and all bolt holes on a flange can be processed at once in each round of drilling, thereby effectively improving the drilling efficiency of the flange.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0033] like Figure 1 As shown, a flange drilling processing device includes a processing table 1, a rotating roller 2, a gear transmission assembly 3, a turntable 4, a fixing component 5, a mounting table 6, a telescopic component 7, a disc 8, a drive motor 9, and a drill bit 10.

[0034] The rotating roller 2 is rotatably connected to the inside of the processing table 1;

[0035] The gear transmission assembly 3 is fixed on the processing table 1 and connected to the rotating roller 2;

[0036] The turntable 4 is welded to one end of the rotating roller 2, and four fasteners 5 with automatic clamping flanges are fixed on the circumference of the turntable 4 (specifically, the fasteners 5 are either a hydraulic three-jaw chuck or a hydraulic four-jaw chuck, and the attached drawing in the instruction manual shows a hydraulic three-jaw chuck).

[0037] The mounting table 6 is fixed on the processing table 1 and the mounting table 6 is fixed with a telescopic component 7.

[0038] The disc 8 is connected to a telescopic component 7 and four synchronously operating drive motors 9 are fixedly mounted on the circumference of the disc 8.

[0039] The drill bit 10 is connected to the drive motor 9 in a one-to-one correspondence.

[0040] Further refinements of the embodiments of this utility model, such as... Figure 2 As shown, a frustum 11 is fixed on the mounting platform 6, and a collection box 12 is placed on one side of the frustum 11. Four limiting rollers 13 that are in contact with the outer wall of the flange are fixed on the circumference of the frustum 11.

[0041] In a further refinement of the embodiment of this utility model, a spray cooling component is provided on the mounting platform 6, which is spaced apart from the fixing member 5 and the drill bit 10. The spray cooling component adopts the existing technology without modification and is not shown in the figure. Its purpose is to cool down during the drilling process. Specifically, it consists of a water tank, a water pump and a nozzle.

[0042] It should be noted that the gear transmission assembly 3, the fixing part 5, the telescopic part 7, and the drive motor 9 are all electrically connected to the controller. The controller is not labeled in the figure, and the fixing part 5 is electrically connected to the controller in a one-to-one correspondence.

[0043] The working process of this utility model is as follows:

[0044] First, place a flange on each hydraulic chuck. The flanges to be drilled should be of the same size and specifications. Once a flange is placed, control the corresponding hydraulic chuck to work and secure the flange. After all flanges are clamped and secured, start the drilling process.

[0045] In the initial state, the fixing member 5 at the bottom of the turntable 4 is directly opposite the disc 8, meaning they are concentric. Then, the controller controls the telescopic member 7 to move, thereby driving several drill bits 10 to approach the flange. At the same time, the controller controls several drive motors 9 to rotate, which then come into contact with several areas of the flange to be processed. In this way, all the bolt holes on a flange can be processed in one operation. During the processing, the surface of the flange and the surface of the drill bits 10 can be effectively cooled by spraying water. The flange in this application needs to have four bolt holes. After the drilling of a flange is completed, the controller controls the gear transmission assembly 3 to operate, thereby realizing the rotation of the turntable 4 at a fixed angle (the rotation angle is preset in the controller. The gear transmission assembly consists of a servo motor, a main gear, and a secondary gear, which is existing technology and will not be described in principle). Then, the adjacent hydraulic chuck and the flange will move to the position of the previous hydraulic chuck. Then, the above process is repeated to perform the drilling process of another flange.

[0046] After all the flanges have been drilled, the drill bit 10 is now far away from the turntable 4 to a safe distance. Then, the clamps on the flanges are released one by one and the flanges are unloaded. After unloading, a new batch of flanges can be loaded and fixed to start a new round of processing. The flanges that have not been drilled will be neatly stacked in the area enclosed by the four limiting rollers 13 and will be in contact with the limiting rollers 13, so that they will not be piled up randomly. After unloading, the flanges can be stacked in the collection box 12 for storage.

[0047] Compared to existing technologies, the flange positioning process in this device is more convenient. After multiple flanges are loaded and positioned, they can be drilled automatically in sequence. During the drilling switching process, the movement positions of several hydraulic chucks are accurate, and all bolt holes on a flange can be processed at once in each round of drilling, thereby effectively improving the drilling efficiency of the flange.

[0048] In some embodiments, such as Figure 3 As shown, a six-degree-of-freedom robotic arm 14 is fixed on the mounting table 6. The six-degree-of-freedom robotic arm 14 is connected to a mounting rod 15, and an electromagnet 16 is fixed on the mounting rod 15. A mounting groove 17 is opened on the processing table 1, and an electric push rod 18 is installed in the mounting groove 17. The retraction rod of the electric push rod 18 passes through the frustum 11 and is connected to a push plate 19 that contacts the limiting roller 13. In this embodiment, after a flange is drilled, it will move to the designated work position with the fixing part 5. At this time, the controller controls the six-degree-of-freedom robotic arm 14 to operate according to the preset program, so that the electromagnet 16 contacts the processed flange. After adsorption, the controller controls the fixing part 5 corresponding to the flange to automatically release the clamp, so as to realize automated transfer. After transfer, Simply place the flange in the collection box 12. After placement, the six-degree-of-freedom robotic arm 14 drives the electromagnet 16 to move above the neatly stacked flange placement area. At this time, the controller controls the electric push rod 18 to move, thereby realizing the coordinated upward movement of several flanges (the purpose of upward movement is to avoid the limit roller 13 obstructing the electromagnet 16 during adsorption, and the extension amount of the electric push rod 18 is preset each time). Then, an unprocessed flange can be adsorbed and placed back on the current work position and clamped again by the hydraulic chuck. In this way, the unloading of the flange after processing and the secondary loading of the new flange can be completed automatically, thereby reducing the labor intensity of manual disassembly and transfer of flanges. That is, the operator only needs to operate on the controller side.

[0049] In other embodiments, such as Figure 3 As shown, a collection box 20 is placed on the processing table 1 below the fixing part 5;

[0050] Further refinements of the above embodiments, such as... Figure 4As shown, a slide rail 21 is symmetrically arranged inside the collection frame 20. A limiting plate 22 is fixed at one end of the slide rail 21, and a filter element 23 is fitted on the slide rail 21. A lifting rod (not shown in the figure) is symmetrically arranged on the filter element 23. In this embodiment, the collection frame 20 can collect the spray water and some debris that fall during the drilling process. At the same time as collection, the filter element 23 can separate the debris from the waste liquid. The waste liquid can then be reused after subsequent processing. The filter screen only needs to be removed and cleaned once periodically. The operation is simple and convenient.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
