Description

Technical Field

[0001] This utility model relates to the field of tapping technology, specifically to a dual-station tapping machine. Background Technology

[0002] In the machining industry, tapping is a crucial process for creating threaded holes, widely used in automotive manufacturing, electronic equipment, aerospace, and other fields. With the advancement of automation and intelligent manufacturing, higher demands are being placed on the machining accuracy, efficiency, and stability of tapping equipment.

[0003] For example, patent CN207205817U discloses a tapping mechanism for a tapping machine, including a base. A column is fixedly connected to one side of the upper surface of the base. A connecting plate is fixedly connected to the column. A hydraulic cylinder, an electric push rod, and a telescopic sleeve rod are fixedly connected to the lower surface of the connecting plate from right to left, located on one side of the column. A hydraulic rod is fixedly connected to the output end of the hydraulic cylinder. A first spring is sleeved on the surface of the telescopic sleeve rod. A fixed box is fixedly connected to the bottom of the electric push rod. An air tank is fixedly connected to one side of the bottom of the fixed box.

[0004] However, its technology has the following problems: First, the material loading process relies heavily on manual operation or simple mechanical assistance. Manual placement of workpieces is not only inefficient, but also prone to inaccurate workpiece positioning due to operational errors, affecting tapping accuracy, and is difficult to meet the needs of large-scale, continuous production.

[0005] Secondly, in terms of lubrication, most equipment uses open spraying or dripping lubricating oil. This method cannot accurately control the amount of lubricating oil, which not only wastes lubricating oil, but also causes lubricating fluid to splash everywhere, polluting the working environment and increasing cleaning and maintenance costs. At the same time, the splashed lubricating fluid may also affect the health of operators.

[0006] Third, the material unloading process lacks automated design. The finished workpieces need to be manually removed or unloaded using complex mechanical structures, which increases labor intensity and reduces the continuity and automation of the production process.

[0007] Based on this, the present invention designs a dual-station tapping machine to solve the above problems. Utility Model Content

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0035] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0036] In some embodiments, please refer to the accompanying drawings. Figures 1-7 A dual-station tapping machine includes a main body 1, a feeding assembly 2, and a tapping device 3;

[0037] The main body of the equipment 1 is connected to the feeding assembly 2 and the tapping device 3;

[0038] The tapping device 3 includes a workbench 31, a processing component 33, and a lubrication component 34. The workbench 31 is mounted on the main body 1 of the equipment. A slot 32 is provided on the right side of the workbench 31. The processing component 33 is mounted on the upper end of the main body 1 of the equipment. The lubrication component 34 is mounted on the upper end of the workbench 31 and is connected to the processing component 33.

[0039] In use, the feeding component 2 feeds the workpiece into the slot 32. Before processing the workpiece, the processing component 33 is lubricated by the lubrication component 34, and then the lubrication component 34 performs tapping processing on the workpiece.

[0040] This utility model achieves automated feeding through the feeding component 2, precise lubrication and splash prevention through the lubrication component 34, synchronous belt pulley component 333 to ensure synchronous processing, and automated unloading design. It improves the efficiency, quality and continuity of tapping processing, simplifies the process and improves the working environment, reduces labor intensity and keeps the environment clean. The processing component 33 adopts a dual-station design, which can simultaneously tap two points of the workpiece, thereby improving the tapping processing efficiency.

[0041] The main body of the equipment 1 includes a support platform 11, a first fixing frame 12, a second fixing frame 13, and a support frame 14. The first fixing frame 12 is fixedly installed on the left side of the support platform 11, the second fixing frame 13 is fixedly installed on the front right side of the support platform 11, and the support frame 14 is fixedly installed on the left front side of the support platform 11.

[0042] The first fixed frame 12 and the second fixed frame 13 are both connected to the feeding component 2, the upper end of the support platform 11 is fixedly connected to the workbench 31, and the processing component 33 is installed on the right side of the support platform 11.

[0043] like Figure 2 and Figure 3 As shown, the feeding assembly 2 includes a first cylinder 21, a slide rail 22, a slider 23, and a second cylinder 25. The first cylinder 21 is fixedly installed on the upper end of the first fixed frame 12, the slide rail 22 is fixedly installed on the upper front side of the support platform 11, the slider 23 is slidably connected to the slide rail 22 and the support platform 11, and the upper end of the slider 23 is provided with a receiving groove 24. The second cylinder 25 is fixedly installed on the upper end of the second fixed frame 13, and the output end of the first cylinder 21 is fixedly connected to the slider 23.

[0044] In this application, when the workpiece is loaded, it is placed on the upper end of the support frame 14 and sent to the receiving groove 24 by an external pushing device. The first cylinder 21 is started and pushes the slider 23 to move, so that the slider 23 moves the workpiece to the worktable 31, so that the receiving groove 24 and the slot 32 are on the same center line. At this time, the second cylinder 25 is started and pushes the workpiece inside the receiving groove 24 into the slot 32. Then the processing assembly 33 processes the workpiece.

[0045] like Figures 3-7 As shown, the processing component 33 includes a linear module slide 331, a motor 332, a synchronous pulley assembly 333, a slide rod 336, a mounting plate 337, and a tapping and drilling assembly. The linear module slide 331 is fixedly installed on the right rear end of the support platform 11, and the output end of the linear module slide 331 is fixedly connected to the mounting plate 337. The lower end of the slide rod 336 is fixedly installed on the right front end of the support platform 11, and the upper end of the slide rod 336 is slidably connected to the mounting plate 337. The motor 332 is fixedly installed on the upper end of the mounting plate 337. There are two sets of tapping and drilling assemblies. One set of tapping and drilling assemblies is connected to the output end of the motor 332, and the other set of tapping and drilling assemblies is connected to the output end of the motor 332 through the synchronous pulley assembly 333. The synchronous pulley assembly 333 is located on the upper end of the mounting plate 337.

[0046] The tapping and drilling assembly includes a connecting rod 334 and a tapping rod 335. The lower end of the connecting rod 334 is fixedly connected to the tapping rod 335. The tapping rod 335 is connected to the lubrication assembly 34. The output end of the motor 332 is fixedly connected to the upper end of a set of connecting rods 334. The two sets of connecting rods 334 are connected by a synchronous belt pulley assembly 333. Both sets of connecting rods 334 are rotatably connected to the mounting plate 337.

[0047] The synchronous belt pulley assembly 333 includes a driving pulley, a driven pulley, and a synchronous belt. The driving pulley is fixedly connected to the outer end of a set of connecting rods 334, and the driven pulley is fixedly connected to the outer end of another set of connecting rods 334.

[0048] The tooth grooves of the drive pulley mesh with the teeth of the timing belt, and the timing belt is driven to move by the friction and meshing force of the tooth surfaces;

[0049] The synchronous belt then drives the driven pulley to rotate through the same meshing method, thereby realizing the power transmission between the two sets of connecting rods 334.

[0050] The lubrication assembly 34 includes a bracket 341, a storage box 342, a first rotating block 343, a second rotating block 344, and a connection port 345. Multiple brackets 341 are provided and fixedly installed on the upper end of the workbench 31. The upper end of the bracket 341 is fixedly connected to the storage box 342. The first rotating block 343 is rotatably connected to the upper end of the storage box 342, and the second rotating block 344 is rotatably connected to the lower end of the storage box 342. The upper end of the storage box 342 is provided with a connection port 345, which is connected to an external lubricating oil supply device.

[0051] Two of each of the first rotating block 343 and the second rotating block 344 are provided and are located on the front and rear sides of the storage box 342 respectively. The interior of the first rotating block 343 and the second rotating block 344 on the front side are threadedly connected to a set of tapping rods 335, and the interior of the first rotating block 343 and the second rotating block 344 on the rear side are threadedly connected to another set of tapping rods 335.

[0052] like Figure 7 As shown, the upper and lower end faces of the storage box 342 are respectively provided with annular sealing grooves, and lip seals are fixedly installed in the grooves. The material of the lip seals is nitrile rubber. The lip of the lip seals is interference-fitted with the outer circular surfaces of the first rotating block 343 and the second rotating block 344 to form a radial seal.

[0053] The function of the lip seal is to prevent lubricating oil from leaking along the outer circumference of the first rotating block 343 and the second rotating block 344, while allowing the first rotating block 343 and the second rotating block 344 to rotate freely.

[0054] When tapping the workpiece, the motor 332 starts and drives the connecting rod 334 to rotate. The connecting rod 334 drives the tapping rod 335 to rotate. Under the action of the synchronous belt pulley assembly 333, the two sets of connecting rods 334 and tapping rods 335 rotate synchronously.

[0055] When the linear module slide 331 is activated, it drives the mounting plate 337 to move downwards, and the slide rod 336 is used to maintain the stability of the mounting plate 337.

[0056] Since the tapping rod 335 is always located inside the material storage box 342, the tapping rod 335 is lubricated with lubricating oil inside the material storage box 342, so that the tapping rod 335 can fully absorb the lubricating oil before descending for processing;

[0057] When the mounting plate 337 drives the connecting rod 334 to move downward, the tapping rod 335 also moves downward. Since the first rotating block 343 and the second rotating block 344 are threadedly connected to the tapping rod 335, when the tapping rod 335 moves downward, it will drive the first rotating block 343 and the second rotating block 344 to rotate. At the same time, the second rotating block 344 will remove excess lubricating oil from the tapping rod 335, effectively preventing lubricating fluid from splashing everywhere during the processing.

[0058] Then, the tapping rod 335 reaches the upper end of the workpiece and continues to move downward, thereby tapping two points on the workpiece. After the workpiece is processed, the next workpiece is sent to the front end of the slot 32 by the feeding assembly 2. The second cylinder 25 is started and pushes the next workpiece into the slot 32. The next workpiece pushes the currently processed workpiece out of the slot 32, completing the unloading, realizing automated unloading, simplifying the process flow, and improving the overall processing continuity.

[0059] It should be noted that this device is only intended to reduce the splashing of lubricant during processing. The lubricant carried out by the tapping rod 335 during descent is normal, and the lubricant dripping onto the workpiece facilitates its processing.

[0060] If you want to reduce the outflow of lubricating oil, you can open a spiral guide groove in the inner hole of the first rotating block 343 and the second rotating block 344, with the spiral direction opposite to the rotation direction of the tapping rod 335.

[0061] A flexible oil scraper ring can be embedded at the bottom of the second rotating block 344. The flexible oil scraper ring is made of polyurethane and its inner diameter is 0.1 to 0.2 mm smaller than the outer diameter of the tapping rod 335.

[0062] The spiral guide groove generates a pumping effect when the tapping rod 335 rotates, pushing excess lubricating oil back to the storage box 342;

[0063] The flexible oil scraper removes excess lubricating oil from the surface of the 335 tap bar, leaving only a very thin oil film for machining lubrication.

[0064] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
