Description

Technical Field

[0001] The utility model relates to the technical field of metal pipes, in particular to a metal pipe drilling device. Background Art

[0002] Metal pipe is a tubular object formed by forming and used for diversion, transportation, isolation and other functions. Currently, common metal pipe materials include stainless steel, copper, aluminum, steel and other metal materials. In the process of processing metal pipes, they need to be drilled.

[0003] When drilling holes in metal pipes, the existing drilling device needs to translate the metal pipes. During the translation process, the metal pipes may be misplaced during movement, and the drilling cannot be performed accurately.

[0004] In the prior art, a Chinese patent with a publication number of CN217370541U is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a drilling device, in particular, a metal pipe drilling device. The technical problem of the utility model is to provide a metal pipe drilling device for clamping and fixing the metal pipe when drilling a hole. The technical implementation scheme of the utility model is: a metal pipe drilling device, including a mounting base, a first guide rod, a sliding frame, a first spring, a motor and a drill bit, a first guide rod is arranged on the upper right side of the mounting base, a sliding frame is slidably arranged above the first guide rod, a first spring is arranged on both sides of the front and rear sides of the sliding frame and between the first guide rod, a motor is arranged on the front side of the sliding frame, and a drill bit is arranged below the output shaft of the motor. The utility model uses a second spring, a clamping block and a handle to play a role of clamping and fixing when drilling a hole in the metal pipe, thereby improving stability. However, in the process of clamping the metal pipe, the clamping force is inconvenient to control, which easily causes the problem of deformation of the metal hose due to excessive clamping force. Utility Model Content

[0005] The purpose of the utility model is to provide a metal pipe drilling device to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A metal pipe drilling device comprises a workbench; a support plate is fixedly installed on the top of the workbench, an electric push rod is fixedly installed on the bottom of the workbench, an output shaft on the top of the electric push rod is fixedly connected to the support plate, a fixed frame is fixedly installed on the top of the workbench, a controller is fixedly connected to the top of the workbench on one side of the fixed frame, a drill bit is arranged at the bottom of the fixed frame on the top of the workbench, a hydraulic cylinder is fixedly installed on the top of the fixed frame, an output shaft at the bottom of the hydraulic cylinder is fixedly connected to the drill bit, a pipe body is placed on the top of the workbench inside the fixed frame, and two sides of the pipe body are arranged A clamping component is used to clamp and limit the pipe body. An adjusting block is fixedly installed on the top of the workbench at one end of the pipe body, and a fixed column is fixedly installed on the other end of the adjusting block. A supporting component is arranged at the other end of the fixed column, and a limiting component is arranged at the other end of the supporting component. The limiting component and the supporting component are both used to support and limit the inner wall of the pipe body. A sleeve is slidably connected to the periphery of the fixed column, and a connecting rod is fixedly installed at one end of the sleeve on the periphery of the fixed column. The connecting rod passes through one end of the adjusting block and is fixedly connected to a connecting plate, and a plug is plugged into the top of the connecting plate.

[0008] According to the different radii of the pipe body, the support plate can be driven to move upward or downward by installing an electric push rod, so that the height of the pipe body can be adjusted to ensure that the center of the pipe body and the center of the fixed column are on the same horizontal line, so as to facilitate the subsequent use of support components and limiting components to support and limit the pipe body, and to facilitate the subsequent use of clamping components to clamp the pipe body. By arranging the pipe body around the periphery of the support components and the limiting components, and the support components and the limiting components are located at the two ends of the bottom of the drill bit respectively, the inner wall of the pipe body can be supported and protected from both ends to prevent the drill bit from drilling too hard or the clamping component from clamping the metal pipe too hard, which may cause the inner wall of the pipe body to deform, thereby protecting the pipe body.

[0009] A further improvement of the technical solution of the utility model is that the supporting component includes a supporting block, one end of which is fixedly connected to a fixed column, and a plurality of push blocks are slidably mounted on the top, bottom and both sides of the supporting block through a plurality of springs, and a rubber pad is attached to the outside of each push block, which fits the inner wall of the pipe body.

[0010] The above-mentioned technical solution is adopted. In this solution, the four push blocks can be squeezed outward by the elastic force of the spring 1 itself, so that the rubber pad 1 and the inner wall of the pipe body are squeezed against each other, thereby supporting and protecting one end of the inner wall of the pipe body at the drilling position to prevent the drill bit from drilling too hard or the clamping component from clamping the metal pipe too hard, which may cause deformation of the inner wall of the pipe body.

[0011] A further improvement of the technical solution of the utility model is that a connecting block is fixedly mounted on one end of each pushing block, and one end of the connecting block is an inclined surface inclined toward the other end outside.

[0012] The above technical solution is adopted. In this solution, by opening a slope at one end of the connecting block, after the sleeve and the connecting block come into contact, the sleeve can squeeze the connecting block, thereby squeezing the four push blocks into the inside of the supporting block.

[0013] A further improvement of the technical solution of the utility model is that the limiting component includes a limiting block, and a plurality of blocks are slidably installed on the top, bottom and both sides of the limiting block through a plurality of springs; the blocks on both sides of the limiting block and the push blocks on both sides of the supporting block are fixedly connected by fixing rods, and a rubber pad is attached to the outside of each block, and the rubber pad fits the inner wall of the pipe body.

[0014] The above-mentioned technical solution is adopted. In this solution, the four blocks can be squeezed outward by the elastic force of the spring 2 itself, so that the rubber pad 2 and the inner wall of the pipe body are squeezed against each other, thereby supporting and protecting the other end of the inner wall of the pipe body at the drilling position to prevent the drill bit from drilling too hard or the clamping component from clamping the metal pipe too hard, thereby causing the inner wall of the pipe body to deform.

[0015] A further improvement of the technical solution of the utility model is that a fixing block is fixedly installed at one end of each stopper, and one end of the fixing block is an inclined surface inclined toward the other end outside.

[0016] The above technical solution is adopted. In this solution, by providing an inclined surface at one end of the fixed block, after the sleeve and the fixed block come into contact, the sleeve can press the fixed block, thereby pressing the stopper toward the inside of the limit block.

[0017] A further improvement of the technical solution of the utility model is that a sleeve is slidably connected to the periphery of the fixed column, a connecting rod is fixedly installed at one end of the sleeve on the periphery of the fixed column, one end of the connecting rod passes through the adjusting block and is fixedly connected to a connecting plate, and a bolt is plugged into the top of the connecting plate.

[0018] The above-mentioned technical solution is adopted. In this solution, by pushing the connecting plate toward the other end, the pipe body can be moved out of the periphery of the supporting component and the limiting component from the other end, so that in the subsequent process of moving the new pipe body to the top of the workbench, the supporting component and the limiting component can be quickly inserted into the interior of the pipe body. There is no need to adjust each push block and stop block individually, thereby improving work efficiency. By inserting the plug into the connecting plate and the adjustment block, the sleeve can be limited.

[0019] A further improvement of the technical solution of the utility model is that the clamping component includes a fixing plate, which is fixedly connected to the top of the workbench, a screw is installed on the internal thread of the fixing plate, the screw extends out of the inner side of the fixing plate and is rotatably connected to a splint through a bearing, a protective pad is attached to the inner side of the splint, and the protective pad is connected to the pipe body.

[0020] The above technical solution is adopted. In this solution, by rotating the screw, the two clamps can be driven closer to each other, so that the protective pad fits against the pipe body, thereby clamping and limiting the pipe body to facilitate subsequent displacement of the pipe during the drilling process.

[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0022] 1. The utility model provides a metal pipe drilling device, which can support and protect the inner wall of the pipe body from both ends through the cooperation between the supporting component and the limiting component, so as to prevent the inner wall of the pipe body from being deformed due to excessive drilling force of the drill bit or excessive clamping force of the clamping component on the metal pipe, thereby protecting the pipe body.

[0023] 2. The utility model provides a metal pipe drilling device. Through the mutual cooperation among the sleeve, spring one, spring two, connecting block and fixing block, after the sleeve is in contact with the connecting block and the fixing block, the four push blocks and the stop blocks can be squeezed into the inside of the supporting block and the limiting block respectively at the same time. In the subsequent process of moving the new pipe body to the top of the workbench, the supporting component and the limiting component can be quickly inserted into the inside of the pipe body, thereby improving work efficiency.

An adjusting block 5 is fixedly installed on the top of the workbench 1 at one end of the pipe body 10, and a fixing column 6 is fixedly installed on the other end of the adjusting block 5. A supporting component 13 is provided at the other end of the fixing column 6, and a limiting component 14 is provided at the other end of the supporting component 13. The limiting component 14 and the supporting component 13 are both used to support and limit the inner wall of the pipe body 10. A sleeve 7 is slidably connected to the periphery of the fixing column 6, and a connecting rod 701 is fixedly installed at one end of the sleeve 7 on the periphery of the fixing column 6. The connecting rod 701 passes through one end of the adjusting block 5 and is fixedly connected to a connecting plate 8, and a plug 801 is plugged into the top of the connecting plate 8.

[0035] In this embodiment, according to the different radii of the pipe body 10, the support plate 11 can be driven to move upward or downward by installing the electric push rod 12, so that the height of the pipe body 10 can be adjusted to ensure that the center of the pipe body 10 and the center of the fixed column 6 are on the same horizontal line, so as to facilitate the subsequent use of the support component 13 and the limiting component 14 to support and limit the pipe body 10, and at the same time facilitate the subsequent use of the clamping component 3 to clamp the pipe body 10. By arranging the pipe body 10 on the periphery of the support component 13 and the limiting component 14, and the support component 13 and the limiting component 14 are just located at the two end positions of the bottom of the drill bit 901 respectively, the inner wall of the pipe body 10 can be supported and protected from both ends to prevent the drill bit 901 from drilling too hard or the clamping component 3 from clamping the metal pipe too hard, which causes the inner wall of the pipe body 10 to deform, thereby protecting the pipe body 10.

[0036] Example 2

[0037] like Figure 2 , Figure 4 and Figure 5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the support component 13 includes a support block 1301, one end of the support block 1301 is fixedly connected to the fixed column 6, and the top, bottom and both sides of the support block 1301 are slidably mounted with a plurality of push blocks 1302 through a plurality of springs 1303, and the outside of each push block 1302 is attached with a rubber pad 1304, and the rubber pad 1304 is in contact with the inner wall of the pipe body 10. The limiting component 14 includes a limiting block 1401, and a plurality of stoppers 1402 are slidably installed on the top, bottom and both sides of the limiting block 1401 through a plurality of springs 1403. The stoppers 1402 on both sides of the limiting block 1401 and the push blocks 1302 on both sides of the supporting block 1301 are fixedly connected through fixing rods 15. A rubber pad 1404 is attached to the outside of each stopper 1402, and the rubber pad 1404 fits with the inner wall of the pipe body 10.

[0038] In this embodiment, the four push blocks 1302 can be squeezed outward by the elastic force of spring 1 1303 itself, so that the rubber pad 1 1304 and the inner wall of the tube body 10 are squeezed against each other. The four stop blocks 1402 can be squeezed outward by the elastic force of spring 2 1403 itself, so that the rubber pad 2 1404 and the inner wall of the tube body 10 are squeezed against each other, thereby supporting and protecting the two ends of the inner wall of the tube body 10 at the drilling position to prevent the drill bit 901 from drilling too hard or the clamping component 3 from clamping the metal tube too hard, which may cause deformation of the inner wall of the tube body 10.

[0039] Example 3

[0040] like Figure 3 , Figure 5 and Figure 6 As shown, on the basis of Example 2, the utility model provides a technical solution: preferably, one end of each push block 1302 is fixedly installed with a connecting block 1305, and one end of the connecting block 1305 is an inclined surface inclined toward the other end outside, one end of each stop block 1402 is fixedly installed with a fixing block 1405, and one end of the fixing block 1405 is an inclined surface inclined toward the other end outside, the periphery of the fixed column 6 is slidably connected with a sleeve 7, one end of the sleeve 7 on the periphery of the fixed column 6 is fixedly installed with a connecting rod 701, the connecting rod 701 passes through one end of the adjusting block 5 and is fixedly connected with a connecting plate 8, and a plug 801 is plugged into the top of the connecting plate 8.

[0041] In this embodiment, by pushing the connecting plate 8 toward the other end, the pipe body 10 can be moved out of the periphery of the supporting component 13 and the limiting component 14 from the other end. After the pipe body 10 is separated from the rubber pad 1304 and the rubber pad 2 1404, the spring 1303 and the spring 2 1403 can squeeze the push block 1302 and the stop block 1402 outward, and at the same time can drive the connecting block 1305 and the fixing block 1405 to move. By providing an inclined surface at one end of the connecting block 1305 and the fixing block 1405, after the sleeve 7 is in contact with the connecting block 1305 and the fixing block 1405, the sleeve 7 can push the connecting block 1305 and the fixing block 1405. 5 and the fixing block 1405 are squeezed, so that the four push blocks 1302 and the stop block 1402 are squeezed toward the inside of the support block 1301 and the limit block 1401 respectively, so as to push the sleeve 7 to the periphery of the support component 13 and the limit component 14, so that when the new pipe body 10 is subsequently moved to the top of the workbench 1, the support component 13 and the limit component 14 can be quickly inserted into the inside of the pipe body 10, without adjusting each push block 1302 and the stop block 1402 separately, thereby improving the work efficiency, and the sleeve 7 can be limited by inserting the plug 801 into the connecting plate 8 and the inside of the adjusting block 5.

[0042] Example 4

[0043] like Figure 1 , Figure 2 and Figure 4 As shown, on the basis of Example 3, the utility model provides a technical solution: preferably, the clamping component 3 includes a fixed plate 301, which is fixedly connected to the top of the workbench 1, and the internal thread of the fixed plate 301 is installed with a screw 303, the screw 303 extends out of the inner side of the fixed plate 301 and is rotatably connected to a splint 302 through a bearing, and a protective pad 304 is attached to the inner side of the splint 302, and the protective pad 304 is connected to the pipe body 10.

[0044] In this embodiment, by rotating the screw rod 303, the two clamping plates 302 can be driven closer to each other, so that the protective pad 304 fits against the pipe body 10, thereby clamping and limiting the pipe body 10 to facilitate subsequent displacement of the pipe during drilling.

[0045] The working principle of the metal pipe drilling device will be specifically described below.

[0046] like Figure 1-Figure 6 As shown, according to the different radii of the pipe body 10, the user can use the electric push rod 12 to drive the support plate 11 to move upward or downward, and adjust the height of the subsequent placement of the pipe body 10 to ensure that the center of the pipe body 10 and the center of the fixed column 6 are on the same horizontal line, and then remove the plug 801, place the pipe body 10 on the top of the support plate 11, and align one end of the pipe body 10 with the sleeve 7. The user can push the pipe body 10 to one end and push the sleeve 7 to one end at the same time. After the sleeve 7 is separated from the rubber pad 1304 and the rubber pad 2 1404, the spring 1303 and the spring 2 1403 can be used to squeeze the four push blocks 1302 and the stop block 1402 outward, so that the rubber pad 1304 and the rubber pad 2 1404 are squeezed against the inner wall of the pipe body 10, thereby supporting and protecting the inner wall of the pipe body 10 at the drilling position, and the pipe is placed. After the position where the body 10 needs to be drilled is moved to directly below the drill bit 901, the user can rotate the screw 303 and drive the two clamps 302 to approach each other, so that the protective pad 304 fits against the pipe body 10, and the pipe body 10 is clamped and limited. After the drilling is completed, the user can push the connecting plate 8 to the other end to move the pipe body 10 out of the periphery of the support component 13 and the limiting component 14. After the sleeve 7 comes into contact with the connecting block 1305 and the fixing block 1405, the sleeve 7 can squeeze the connecting block 1305 and the fixing block 1405, and at the same time squeeze the four push blocks 1302 and the stop block 1402 into the inside of the support block 1301 and the limiting block 1401 respectively, thereby pushing the sleeve 7 to the periphery of the support component 13 and the limiting component 14, so as to facilitate the subsequent movement of the new pipe body 10 to the periphery of the support component 13 and the limiting component 14.

[0047] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
