Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a drilling machine. Background Technology

[0002] In the water treatment and biopharmaceutical industries, various pipes made of different materials are needed for collecting or diverting filtered liquids, such as polysulfone and ABS collection pipes. These pipes require single or multiple rows of equidistant through-holes to be machined on their surface during processing. Since most of these pipes cannot be injection molded, these through-holes are typically created through post-processing.

[0003] Drilling is a common machining method, but efficiently and accurately machining multiple rows of equidistant through holes on a circular pipe, while also accommodating collection pipes of different sizes and materials, and ensuring that the machined through holes are smooth and free of debris, is a very challenging task.

[0004] Currently, there are two main methods for drilling holes in collection pipes. One is using a handheld drilling machine or bench drill, which is more common and has the advantage of being convenient and quick to operate. However, its disadvantages include lower processing accuracy, inability to achieve equidistant processing, and difficulty in ensuring hole chipping and surface finish, which basically fails to meet product quality requirements. The other method is using a special drilling machine modified from a milling machine, which utilizes the programmable function of the milling machine to achieve precise drilling. Although this can improve processing accuracy, its equipment structure is more complex, manufacturing costs are high, and maintenance is difficult, which limits its widespread application in actual production.

[0005] In summary, existing methods for drilling and processing collection pipes have many shortcomings in terms of processing accuracy, efficiency, cost, and maintenance, making it difficult to meet the demands of the water treatment and biopharmaceutical industries for high-quality collection pipes. Therefore, there is an urgent need for a technical solution that can efficiently, accurately, and cost-effectively process multiple rows of holes at equal intervals in circular pipes.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0040] This utility model provides a drilling machine that can be used to perform equidistant drilling on pipes. (See reference...) Figure 1 As shown, the drilling machine includes a drilling device 100, a workpiece fixing device 200, a workpiece clamping device 300, a visual control device 400, and a frame 500.

[0041] The drilling device 100 is located on one side of the top of the frame 500. The workpiece fixing device 200 is horizontally located on the top of the frame 500, with a portion located in front of the drilling device 100. The workpiece fixing device 200 is located inside the workpiece fixing device 200 and in front of the drilling device 100.

[0042] For details, please refer to Figure 2 , Figure 3 As shown, the drilling device 100 includes a drilling assembly 110, a cooling assembly 120, a fixing assembly 130, and a drilling transmission module 140;

[0043] The fixing component 130 includes a fixing base plate 131, a fixing back plate 132, and a fixing panel 133. The fixing back plate 132 is fixedly connected to the fixing base plate 131 and slidably connected to the fixing panel 133 via a slide rail.

[0044] The drilling transmission module 140 is disposed on the fixed back plate 132, the drilling assembly 110 is disposed on the fixed panel 133, and the fixed base plate 131 is fixedly installed on one side of the top of the frame 500.

[0045] The drilling assembly 110 includes a drill bit 111 and a drilling machine 112; the drill bit 111 is a detachable structure, and those skilled in the art can replace it with different specifications of drill bit 111 according to actual processing requirements during use;

[0046] The cooling assembly 120 includes a nozzle 121, which is located in the vicinity of the drilling assembly 110, preferably near the drill bit 111;

[0047] In actual operation, the drilling transmission module 140 drives the drilling assembly 110 to move in the vertical direction. At the same time, the drilling machine 112 drives the drill bit 111 to rotate and drill holes. The nozzle 121 sprays water onto the drill bit 111 to cool it down quickly and prevent material from sticking during drilling.

[0048] For details, please refer to Figure 4 As shown, the workpiece fixing device 200 includes a clamping module 210, a transmission module 220, a sliding component 230, and a lifting module 240;

[0049] The sliding assembly 230 includes a track 231 and a sliding platform 232. The track 231 is laid on the top of the frame 500 and is perpendicular to the working direction of the drilling assembly 110. The upper side of the sliding platform 232 is provided with the clamping module 210 and the lower side is provided with the transmission module 220.

[0050] The clamping module 210 is a three-jaw clamping module, including large and small models. When using it, those skilled in the art can replace the clamping module 210 with different specifications according to actual needs to adapt to different tube types.

[0051] See Figure 5 As shown, the lifting module 240 is located on the front side of the drilling device 100, and includes a material-supporting slide rail 241, a material-supporting slider 242, and a material-supporting component 243. The material-supporting component 243 is fixedly connected to the material-supporting slider 242 via a connector. The material-supporting slide rail 241 is mounted on the frame 500. The material-supporting slider 242 can move vertically along the material-supporting slide rail 241, thereby driving the material-supporting component 243 to move up and down, thus supporting pipe fittings of different specifications and keeping them horizontal. Preferably, the material-supporting component 243 is an inverted hourglass-shaped support block. Figure 6 As shown, the hourglass-shaped waist supports the support component and forms a limit;

[0052] In actual operation, the clamping module 210 clamps one end of the pipe fitting, and the lifting module 240 supports the other end of the pipe fitting to keep the pipe fitting horizontal. The transmission module 220 drives the sliding platform 232 to slide along the track 231, causing the pipe fitting to move horizontally and changing the drilling processing area.

[0053] For details, please refer to Figure 7 As shown, the workpiece clamping device 300 is located on the lower side of the drilling assembly 110, and includes a clamping clamp 310 and a clamping drive module.

[0054] The clamping clamp 310 includes two pairs of arc-shaped clamps, which are respectively located on both sides below the drill bit 111. The two arc-shaped openings of each pair of arc-shaped clamps are opposite each other, forming an arc-shaped space on the inner side.

[0055] The clamping drive module includes a guide 320, a horizontal rail 331, a horizontal slider 332, a transmission rod 333, a vertical rail 341, a vertical slider 342, and a drive component 343;

[0056] The guide member 320 is a Y-shaped workpiece, with guide rails running through both sides on the upper part, and one side of the lower part connected to the drive member 343, and the other side connected to the vertical slider 342. The vertical slider 342 can move in the vertical direction along the vertical rail 341.

[0057] One end of the transmission rod 333 is inserted into the guide rail and can move along the guide rail, while the other end is fixedly connected to the horizontal slider 332.

[0058] The horizontal slider 332 is equipped with the clamping clip 310, which can move horizontally along the horizontal track 331;

[0059] In actual operation, the driving component 343 drives the guide component 320 to move vertically along the vertical track 341 via the vertical slider 342, thereby driving the transmission rod 333 to move within the guide track. When the guide component 320 moves downward, the transmission rods 333 of the pair of clamping clamps 310 move away from each other, causing the pair of horizontal sliders 332 fixedly connected to them to move along the horizontal track 331 towards both ends of the track. The clamping clamps 310 open, releasing the workpiece. When the guide component 320 moves upward, the transmission rods 333 move closer to each other, causing the horizontal sliders 232 to move along the horizontal track 331 towards the center of the track. The clamping clamps 310 close, clamping and fixing the workpiece to prevent it from shaking during processing, which would affect the processing quality and accuracy.

[0060] Specifically, the visual control device 400 is mounted on the top of the frame 500 via a support rod, and includes a human-machine interface screen, a PLC device, and a servo motor module. For processing pipes of different materials and specifications, experience parameters and control commands can be set through the human-machine interface screen to achieve intelligent and automated processing of the pipes. In addition, an emergency stop button is also provided to ensure that the power can be quickly cut off manually in case of an accident during processing, so that the equipment stops working.

[0061] Preferred options, please refer to Figure 8 As shown, the cooling assembly 120 also includes a water receiving tank 122, which is located between the clamping clamps 310 and directly below the drill bit 111. The water receiving port of the water receiving tank 122 is U-shaped, and the U-shaped recess can accommodate the workpiece. In use, it can reduce the splashing of water droplets when the nozzle 121 sprays water to the drill bit 111 to cool it down, and it can also block some of the splashing of processing debris, thereby reducing the risk of personnel injury caused by debris splashing.

[0062] More preferably, the cooling assembly 120 further includes a filter screen and a water receiving tank. The filter screen is located at the outlet of the water receiving tank 122 and can intercept processing debris and other impurities in the wastewater. The water receiving tank receives the wastewater after it has been filtered by the filter screen and can be recycled for rapid cooling of the drill bit 111.

[0063] Preferably, the drilling rig 120 also functions as a water pump.

[0064] Preferably, the drilling transmission module 140 and the transmission module 220 are ball screws, and the driving component 343 is a cylinder mechanism.
