Abstract
Description
Technical Field
[0001] This invention relates to the field of machine tool technology, and in particular to a multi-station fastener end face drilling and tapping platform. Background Technology
[0002] Drilling and tapping the end face of fasteners is a common process in the machining field. Currently, there are various drilling and tapping equipment on the market that can perform basic drilling and tapping operations on the end face of fasteners. Some equipment also attempts to adapt to multi-station processing needs, and complete the processing switching of different stations through a simple position adjustment structure to meet basic production and processing requirements.
[0003] Existing fastener end face drilling and tapping equipment has poor multi-station processing adaptability, making it difficult to achieve flexible drill bit position adjustment and quickly and accurately correspond to different processing stations. In addition, ordinary simple tapping equipment generally lacks a dedicated drill bit positioning structure, and the processing accuracy is easily reduced due to drill bit offset and vibration during processing. On the other hand, the few precision drilling and tapping equipment that can achieve accurate processing have complex structures and high costs, resulting in high equipment investment costs and failing to meet the low-cost processing needs of small processing plants.
[0004] Based on this, a multi-station fastener end face drilling and tapping platform is proposed. Summary of the Invention
[0005] The purpose of this invention is to provide a multi-station fastener end face drilling and tapping platform in order to solve the above-mentioned problems.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A multi-station fastener end face drilling and tapping platform includes a worktable, a vertical rod fixedly connected to the upper end of the worktable, a lifting block slidably connected to the vertical rod, a translation platform connected between the lifting blocks, a drill bit and a button for controlling the operation of the drill bit connected to one side of the translation platform, and an auxiliary mechanism for positioning the drill bit and assisting the fastener end face in drilling and tapping connected to the translation platform.
[0007] Preferably, a spring is connected between the lifting block and the work platform, and the spring is sleeved on the vertical rod.
[0008] Preferably, two sets of crossbars are fixedly connected between the lifting blocks, and the translation platform is slidably sleeved on the crossbars.
[0009] Preferably, two sets of crossbars are slidably connected through the translation platform, and the drill bit is fixedly connected to one end of the crossbars.
[0010] Preferably, the auxiliary mechanism includes a cylinder, the non-extension end of which is slidably connected between the vertical rods, the extension end of which is connected to a pressing frame, and an anti-slip plate for abutting against the horizontal rod is connected to the pressing frame. An abutment groove that cooperates with the anti-slip plate is provided on the translation platform.
[0011] Preferably, a horizontal bar is fixedly connected between the upper ends of the vertical rods, and the upper end of the cylinder is slidably connected to the horizontal bar via a collar.
[0012] Preferably, a limiting frame is connected to the translation platform, and the limiting frame is sleeved on the telescopic end of the cylinder.
[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1.

It can quickly adapt to any processing position on the worktable, greatly simplify the position adjustment operation of multi-station processing, and improve the adaptability and adjustment efficiency of multi-station processing.
[0014] 2. This application achieves stable fixing of the drill bit during machining by adopting a cylinder-driven pressing and positioning structure, avoiding the shaking problem caused by manual support. At the same time, the cylinder extension and retraction can provide continuous and stable feed power for the drill bit, effectively improving drilling and tapping accuracy and ensuring the quality consistency of multi-station machining.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] Please see Figures 1-3 The present invention provides a technical solution: A multi-station fastener end face drilling and tapping platform includes a worktable 1, with a vertical rod 2 fixedly connected to the upper end of the worktable 1. The upper end of the worktable 1 is adapted to be equipped with a platform for clamping and fixing workpieces at multiple stations, which can meet the needs of multi-station drilling and tapping operations. A lifting block 3 is slidably connected to the vertical rod 2, and a translation table 9 is connected between the lifting blocks 3. A drill bit 7 and a button 13 for controlling the operation of the drill bit 7 are connected to one side of the translation table 9. An auxiliary mechanism is connected to the translation table 9 to position the drill bit 7 and assist the fastener end face in drilling and tapping.
[0019] Specifically, such as Figure 1 As shown, a spring 4 is connected between the lifting block 3 and the worktable 1. The spring 4 is sleeved on the vertical rod 2. The spring 4 can extend and retract with the vertical movement of the lifting block 3, providing elastic support for the reset of the lifting block 3, and at the same time buffering the vertical vibration force generated during the drilling process.
[0020] Specifically, such as Figure 2 As shown, two sets of crossbars 8 are fixedly connected between the lifting blocks 3. The translation platform 9 is slidably sleeved on the crossbars 8. The translation platform 9 can slide horizontally along the crossbars 8 to realize the horizontal adjustment of the drill bit 7. It can cooperate with the movement of the lifting blocks 3 to complete the multi-directional position adaptation of the drill bit 7.
[0021] Specifically, such as Figure 1 and Figure 3 As shown, two sets of crossbars 12 are slidably connected through the translation table 9. The drill bit 7 is fixedly connected to one end of the crossbars 12. The crossbars 12 can slide horizontally along the translation table 9, thereby driving the drill bit 7 to adjust its horizontal and vertical position. In coordination with the movement of the translation table 9 and the lifting block 3, the drill bit 7 can be moved and adjusted in the XYZ three-dimensional direction, ensuring that the drill bit 7 can be accurately moved to any processing position on the worktable 1.
[0022] Specifically, such as Figure 3 As shown, the auxiliary mechanism includes a cylinder 14. The non-telescopic end of the cylinder 14 is slidably connected between the vertical rods 2. The telescopic end of the cylinder 14 is connected to a pressing frame 15. An anti-slip plate 16 for abutting against the horizontal bar 3 12 is connected to the pressing frame 15. The translation table 9 is provided with an abutting groove 11 that cooperates with the anti-slip plate 16. The anti-slip plate 16 can increase the friction between itself and the horizontal bar 3 12. The abutting groove 11 limits the pressing position of the anti-slip plate 16 to ensure that the anti-slip plate 16 is accurately pressed against the horizontal bar 3 12 and avoids pressing deviation.
[0023] Specifically, such as Figure 1 As shown, a horizontal bar 5 is fixedly connected between the upper ends of the vertical bar 2. The upper end of the cylinder 14 is slidably connected to the horizontal bar 5 through a collar 6. The collar 6 can slide along the horizontal bar 5, so that the cylinder 14 moves synchronously with the horizontal movement of the translation table 9, ensuring that the pressing and positioning effect of the cylinder 14 on the horizontal bar 12 is always effective.
[0024] Specifically, such as Figure 3 As shown, a limiting frame 10 is connected to the translation stage 9. The limiting frame 10 is sleeved on the telescopic end of the cylinder 14. The limiting frame 10 radially limits the telescopic end of the cylinder 14 to prevent the cylinder 14 from retracting excessively, causing the pressing frame 15 to separate from the abutment groove 11, thus ensuring the pressing stability of the pressing frame 15 and the anti-slip plate 16.
[0025] In summary, the multi-station fastener end face drilling and tapping platform provided in this embodiment first adjusts the position of the drill bit 7 in the XYZ three-dimensional direction according to the position of the workpiece to be processed on the worktable 1. This is achieved by moving the lifting block 3 vertically along the vertical rod 2, the translation table 9 horizontally along the second horizontal rod 8, and the third horizontal rod 12 horizontally along the translation table 9. This precisely moves the drill bit 7 to the required drilling and tapping position. Then, the cylinder 14 is operated, and the telescopic end of the cylinder 14 extends to push the pressing frame 15 downward. This causes the anti-slip plate 16 on the pressing frame 15 to move in the abutment groove 11 and tightly abut against the third horizontal rod 12, fixing the third horizontal rod 12 and thus locking the position of the drill bit 7. This prevents shaking caused by manual support during drilling and tapping. The cylinder 14 extends to push one end of the drill bit 7 to tightly abut against the workpiece machining position. Pressing button 13 controls the drill bit 7 to rotate, starting the drilling and tapping operation. During the drilling and tapping process, the cylinder 14 continues to extend, providing continuous feed power for the downward machining of the drill bit 7, ensuring the smooth progress of the drilling and tapping operation. After the machining is completed, first release button 13 to stop the drill bit 7 from rotating, then control the extension end of the cylinder 14 to retract, the anti-slip plate 16 disengages from the crossbar 3 12, and the position lock of the drill bit 7 is released. Finally, by moving the lifting block 3, the translation table 9 and the crossbar 3 12, the drill bit 7 is moved to the next machining station. Repeating the above operation can complete the drilling and tapping operation in multiple stations. The overall operation is convenient, the machining accuracy is high, and the multi-station adaptability is good.
