[0002] In the field of machining, vertical drilling machines and vertical milling machines are two of the most common metal cutting machine tools, mainly used for drilling holes and milling planes, respectively. In actual production, many workpieces often need to complete multiple processes such as drilling and milling at the same time.

[0003] According to the announcement number CN223029038U, a vertical shaft drilling and milling machine is announced. In this vertical drilling and milling machine, the workpiece is placed on the platform and the milling head is used to drill and mill the workpiece.

[0004] However, vibration and tool deflection are prone to occur during processing, and the stability and centering of workpiece clamping are another key to ensuring accuracy. The above-mentioned equipment lacks an effective workpiece clamping device, which seriously affects the position accuracy of the hole and leads to the generation of batches of scrap. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that is different from the existing technology.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Reference Figures 1-4 A high-precision vertical drilling and milling integrated processing equipment includes a base 1, a linear motor 3 on the top of the base 1, and a placement table 5 fixed to the top of the slider of the linear motor 3 by bolts. The placement table 5 has an internal cavity. The top of the placement table 5 has a first groove 6. Two clamping plates 7 are slidably connected in the first groove 6. Anti-slip textures are provided on one side of the two clamping plates 7. The anti-slip textures on the two clamping plates 7 can effectively increase the friction between the clamping plates and the workpiece and prevent the workpiece from shifting due to vibration during processing. The bottom of the two clamping plates 7 is rotatably connected to the connecting rod 17 through a fixed shaft. The two connecting rods 17 are located in the cavity. A sleeve is sleeved on the outside of the fixed shaft. The sleeve rotates 17 within the first groove 6. A first cylinder 4 is fixed to one side of the placement platform 5 by bolts. The first cylinder 4 is a self-locking cylinder, and the model can be selected as SDA20x50. One end of the first cylinder 4 passes through the placement platform 5 and is rotatably connected to two connecting rods 17. In use, with the first cylinder 4 connected to an external air source via an air pipe, the workpiece to be processed is placed on the placement table 5. The first cylinder 4 is started, and its piston rod extends and retracts, driving the connecting rod 17 to move. This causes the two clamping plates 7 to move closer to each other along the first sliding groove 6, using the anti-slip texture to clamp the workpiece. This effectively prevents the workpiece from shifting during processing, improves the stability and centering of the clamping, and reduces processing errors caused by workpiece shaking from the source.

[0017] In this utility model, a fixing frame 2 is fixed to the top of the base 1 by bolts, a second cylinder 15 is fixed to one side of the fixing frame 2 by bolts, a second sliding groove 11 is provided on one side of the fixing frame 2, a slider 16 is slidably connected in the second sliding groove 11, and one end of the second cylinder 15 is fixed to the slider 16, and one end of the slider 16 is fixed to the slide frame 8 by bolts. The second cylinder 15 is a self-locking cylinder, and the model can be selected as SDA20x50. The second cylinder 15 is connected to an external air source through an air pipe. When in use, the second cylinder 15 can be activated, and its piston rod pushes the slider 16 to move longitudinally along the second slide groove 11, thereby driving the slide 8 to adjust its height synchronously to adapt to the processing requirements of different workpieces. A through groove 13 is provided on one side of the slide 8. A threaded block 12 is slidably connected in the through groove 13. A drilling and washing machine 10 is provided on one side of the threaded block 12. The drilling and washing machine 10 includes a motor, a drill bit seat fixed to the output shaft of the motor, and a detachable drill bit. In particular, a drive motor 14 is fixed to one side of the slide 8 by bolts, a threaded rod 9 is rotatably connected in the through groove 13, and one end of the output shaft of the drive motor 14 is connected to the threaded rod 9 through a coupling. The threaded block 12 can slide laterally in the through groove 13. By adjusting the position of the threaded block 12, the lateral processing coordinates of the drilling and washing machine 10 can be flexibly changed.

[0018] When in use, the drive motor 14 can be started, and its output shaft drives the threaded rod 9 to rotate in the through groove 13 through the coupling. Since the threaded block 12 is threadedly connected to the threaded rod 9, the rotation of the threaded rod 9 will drive the threaded block 12 to move smoothly laterally along the through groove 13, realizing the automatic adjustment of the lateral position of the drilling and washing machine 10. There is no need for manual pushing of the threaded block 12, which improves the convenience of operation and the accuracy of position control. Two corrugated covers 18 are fixed to one side of the carriage 8 by bolts, and one end of the corrugated cover 18 is fixed to the threaded block 12. The corrugated cover 18 can protect the threaded rod 9 in the through groove 13 and prevent dust and debris from affecting the accuracy of the threaded rod 9.

[0019] Working principle: When in use, place the workpiece to be processed on the placement table 5, start the first cylinder 4, its piston rod extends and retracts to drive the connecting rod 17 to move, thereby causing the two clamping plates 7 to move closer to each other along the first sliding groove 6, using the anti-slip texture to clamp the workpiece. Then, according to the processing position requirements, start the drive motor 14 to drive the threaded rod 9 to rotate, causing the threaded block 12 to move laterally along the through groove 13, and adjust the drilling and washing machine 10 to a suitable lateral position. Then, start the second cylinder 15 to push the slider 16 up and down along the second slide groove 11, which will drive the slide 8 and the drilling and milling machine 10 to move longitudinally to the processing height. Then the drilling and milling machine 10 can be started to perform drilling and milling operations on the workpiece. During the whole process, the linear motor 3 can drive the placement table 5 to move as a whole. With the position adjustment of the drilling and milling machine 10, continuous processing of different areas of the workpiece can be achieved. The coordinated work of each structure ensures processing accuracy and efficiency.
