Description

Technical Field

[0001] This utility model relates to the field of tapping devices, specifically to a tapping device for processing threaded steel pipes. Background Technology

[0002] Tapping is a machining process that involves creating threads on a part to connect it with other parts. Cutting fluid is typically used during tapping. It forms an oil film on the workpiece and tool surfaces and penetrates even the smallest metal gaps and irregularities, thus reducing tool wear.

[0003] Existing tapping devices still have the following problems when in use: When the existing tapping device is in use, the cutting fluid may splash when it comes into contact with the rotating cutting head, which makes it difficult to collect and clean the splashed cutting fluid later.

[0004] Therefore, it is necessary to invent a tapping device for processing threaded steel pipes to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a tapping device for threaded steel pipe processing, in order to solve the problem mentioned in the background art that when the existing tapping device is in use, the cutting fluid may splash when it comes into contact with the rotating cutting head, which makes it difficult to collect and clean the splashed cutting fluid later.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tapping device for processing threaded steel pipes, comprising a worktable, a top plate fixedly connected to the top of the worktable by a vertical rod, a cylinder being fitted inside the top plate, and a tapping component being installed at the output end of the cylinder; a liquid storage cavity being provided inside the worktable, and a clamping channel being opened above the liquid storage cavity, and a steel pipe being clamped inside the clamping channel; a leakage hole being provided inside the worktable, and a conical surface being provided on the surface of the worktable; a support column being fixedly installed inside the liquid storage cavity by a connecting block, and the steel pipe being placed on the support column; a liquid outlet pipe being fitted inside the top plate, and a splash-proof component being fitted outside the liquid outlet pipe.

[0007] Preferably, the drilling component includes a drilling machine and a threaded drill bit that is drivenly connected to the output shaft of the drilling machine. The threaded drill bit penetrates deep into the steel pipe and is slidably connected to the pre-reserved columnar inner cavity inside the support column, which facilitates the drill bit to perform thread processing on the round pipe.

[0008] Preferably, the anti-splash assembly includes a top barrel fixedly connected to the outer wall of the cylinder output end, and a cylindrical barrel is slidably installed on the outside of the top barrel, with the lower end of the cylindrical barrel in movable contact with the top wall of the worktable, so that the top barrel and the cylindrical barrel can form a closed space to prevent the cutting oil used in tapping from splashing.

[0009] Preferably, the splash-proof assembly further includes side blocks that are fixedly connected to the two side walls of the top barrel, and the outer wall of the side blocks is slidably connected to the vertical groove reserved inside the barrel to ensure smooth up-and-down movement of the top barrel and the barrel.

[0010] Preferably, there are two side blocks, and the two side blocks are symmetrically arranged with reference to the central axis of the cylinder. The outer wall of the side block is attached to the inner wall of the vertical groove to achieve a sliding connection between the top cylinder and the cylinder, so as to ensure the stability of the top cylinder and the cylinder's vertical movement.

[0011] Preferably, both the upper and lower ends of the vertical groove are closed, so that the top barrel and the round barrel will not separate.

[0012] Preferably, the splash-proof assembly further includes a light rod fixedly connected to the top plate and the worktable, and the light rod penetrates the inside of the cylinder and is slidably connected to the cylinder in an up-down manner, and the light rod penetrates the inside of the side block and is slidably connected to the side block in an up-down manner, so as to ensure the stability of the cylinder's up-down movement.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] This invention uses a cylinder to lower the top barrel and a cylindrical barrel fitted outside the top barrel, which then descend synchronously. When the bottom of the cylindrical barrel contacts the top of the worktable, the top barrel and the cylindrical barrel form a closed space. At this time, the cylinder continues to descend, causing the drill bit to descend and contact the steel pipe to be processed for threading. The cutting fluid flowing out of the outlet pipe assists in the threading process. The top barrel and the cylindrical barrel form a closed space, preventing the cutting oil from splashing when it comes into contact with the rotating drill bit during tapping.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model provides, for example Figure 1-4 The tapping device for processing threaded steel pipes shown includes a workbench 1. A top plate 2 is fixedly connected to the top of the workbench 1 via a vertical rod 3. A cylinder 4 is fitted inside the top plate 2, and a tapping part 5 is installed at the output end of the cylinder 4. A liquid storage chamber 9 is provided inside the workbench 1, and a clamping channel 6 is opened above the liquid storage chamber 9. A steel pipe is clamped inside the clamping channel 6. A drain hole 8 is provided inside the workbench 1, and a conical surface 7 is provided on the surface of the workbench 1. A support column 10 is fixedly installed inside the liquid storage chamber 9 via a connecting block 11. The steel pipe is placed on the support column 10. A liquid outlet pipe 12 is fitted inside the top plate 2, and a splash-proof component 13 is fitted outside the liquid outlet pipe 12.

[0024] During use, the cylinder 4 is activated to descend, and the drilling component 5 is activated to rotate the drill bit. Under the influence of gravity, the descent of the cylinder 4 causes the top barrel 131 and the cylindrical barrel 132 fitted outside the top barrel 131 to descend synchronously. When the bottom of the cylindrical barrel 132 contacts the top of the worktable 1, the top barrel 131 and the cylindrical barrel 132 form a closed space. At this time, the cylinder 4 continues to descend, causing the drill bit to descend and contact the steel pipe to be processed for threading. At this time, the cutting fluid flowing out of the liquid outlet pipe 12 assists in threading. The cutting fluid may splash when it comes into contact with the rotating drill bit. The closed space formed by the top barrel 131 and the cylindrical barrel 132 prevents the cutting fluid from splashing over a large area and being difficult to clean. The cutting fluid falls into the liquid storage chamber 9 through the drain hole 8, which is convenient for subsequent collection and treatment through the cleaning port reserved on the back of the liquid storage chamber 9.

[0025] The drilling component 5 includes a drilling machine and a threaded drill bit that is connected to the output shaft of the drilling machine. The threaded drill bit penetrates deep into the steel pipe and slides into the columnar cavity reserved inside the support column 10, which facilitates the drill bit to perform thread processing on the round pipe. At the same time, the lower end of the drill bit extends to the middle height position of the cylindrical barrel 132. This means that the top barrel 131 and the cylindrical barrel 132 must first form a closed space before the drill bit can process the steel pipe. When the drill bit contacts the steel pipe, the cutting fluid flows out of the liquid outlet pipe 12 to assist in the processing.

[0026] To prevent cutting fluid from splashing when in contact with the rotating drill bit, the splash guard 13 includes a top barrel 131 fixedly connected to the outer wall of the output end of the cylinder 4, and a cylindrical barrel 132 is slidably mounted on the outside of the top barrel 131. The lower end of the cylindrical barrel 132 is in movable contact with the top wall of the worktable 1, so that the top barrel 131 and the cylindrical barrel 132 can form a closed space to prevent the cutting oil used for tapping from splashing. The splash guard 13 also includes side blocks 133 fixedly connected to the two side walls of the top barrel 131, and the outer wall of the side blocks 133 is slidably connected to the vertical groove 134 reserved inside the cylindrical barrel 132 to ensure smooth up and down movement of the top barrel 131 and the cylindrical barrel 132.

[0027] The splash-proof component 13 also includes a light rod 135 that is fixedly connected to the top plate 2 and the worktable 1. The light rod 135 passes through the inside of the cylinder 132 and is slidably connected to the cylinder 132 in the upper and lower position. The light rod 135 also passes through the inside of the side block 133 and is slidably connected to the side block 133 in the upper and lower position, ensuring that the cylinder 132 moves stably in the upper and lower position.

[0028] In this way, the downward movement of cylinder 4 drives the top barrel 131 and the cylindrical barrel 132 fitted outside the top barrel 131 to descend synchronously. When the bottom of the cylindrical barrel 132 contacts the top of the worktable 1, the top barrel 131 and the cylindrical barrel 132 form a closed space. At this time, the cylinder 4 continues to descend, driving the drill bit to descend and contact the steel pipe to be processed to perform thread processing. The cutting fluid flowing out of the liquid outlet pipe 12 assists in thread processing. The top barrel 131 and the cylindrical barrel 132 form a closed space to prevent the cutting oil from splashing when it comes into contact with the rotating drill bit during tapping.

[0029] There are two side blocks 133, and the two side blocks 133 are symmetrically arranged with reference to the central axis of the cylinder 132. The outer wall of the side block 133 is attached to the inner wall of the vertical groove 134 to achieve a sliding connection between the top cylinder 131 and the cylinder 132, ensuring the stability of the vertical movement of the top cylinder 131 and the cylinder 132. The upper and lower ends of the vertical groove 134 are closed, so that the top cylinder 131 and the cylinder 132 will not separate.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
