Description

Technical Field

[0001] This invention belongs to the field of mechanical processing equipment technology, and in particular relates to a CNC drilling and milling integrated machine for machining lead screw seats. Background Technology

[0002] The machining of lead screw seats is a crucial step in mechanical manufacturing. It primarily supports and secures the lead screw, ensuring its stable operation and precise transmission. During machining, the first step is to select suitable materials, such as high-quality steel, based on design requirements to ensure the lead screw seat possesses sufficient strength and wear resistance. The machining process encompasses turning, milling, and drilling. Turning ensures the lead screw seat meets dimensional accuracy and surface finish requirements; milling is used to machine the mounting surface and positioning grooves; and drilling precisely creates holes for mating with the lead screw and for mounting bolts. Strict control over dimensional accuracy and geometric tolerances is essential during machining to ensure a good fit between the lead screw seat and the lead screw, guaranteeing the efficient and stable operation of the entire transmission system.

[0003] A Chinese patent application (or patent) with publication number CN222134066U discloses a CNC drilling and milling machine with a lead screw seat, including a welding frame. The welding frame has a vertical platform and a horizontal platform inside. The vertical platform is provided with a Z-axis track device and a first tool controlled by the Z-axis track device. The horizontal platform is provided with an X-axis track device, a Y-axis track device controlled by the X-axis track device, and a pneumatic clamp controlled by the Y-axis track device. The feature is that it also includes a lead screw seat and a CNC panel mounted on the welding frame. The pneumatic clamp is used to hold the lead screw seat.

[0004] However, the above-mentioned device still has the following problems during implementation: When using lubricating fluid to cool the cutting process, the cutting fluid carries a large amount of metal chips, abrasive particles and other impurities. If not cleaned in time, it will not only affect the machining quality, but may also accelerate tool wear and even damage the machine tool. A separate filtration device is required to circulate and filter the cutting fluid, which makes it impossible to carry out machining and filtration simultaneously, making it difficult to achieve truly efficient continuous machining and affecting the overall production efficiency.

[0005] To address these issues, we provide a CNC drilling and milling machine for machining lead screw seats. Summary of the Invention

[0039] Example 3: Please refer to Figures 1-10Based on Embodiments 1 and 2, a vertical rod 15 is fixedly connected to the top of the pressure tube 604. The top of the vertical rod 15 passes through the filter cylinder 602 and is fixedly connected to a push plate 16. A first spring is sleeved on the surface of the vertical rod 15. A cooler 17 is installed through the bottom of the cooling box 603. A liquid pump 18 is connected to one side of the cooling box 603. A delivery pipe 19 is connected to the outlet of the liquid pump 18. A drain pipe 20 is connected to one side of the pressure tube 604. A sliding groove is opened on one side of the filter cylinder 602. A limit plate 21 is fixedly connected to the surface of the impact rod 502. A second spring is sleeved on the surface of the impact rod 502. A support grid 22 is fixedly connected inside the processing table 1. A fixing screw is installed through the top of the support grid 22. A clamping plate is threadedly connected to the surface of the fixing screw.

[0040] Specifically: An auxiliary rod 12 is movably connected inside the conveying shell 8. A second synchronous wheel 13 is fixedly connected to the surface of the auxiliary rod 12. One end of the auxiliary rod 12 passes through the interior of the filter box 601 and is fixedly connected to a cam 14. When the cam 14 rotates, it can push the pressure tube 604 in the filter press assembly 6 to move, realizing pressure filtration. A vertical rod 15 is fixedly connected to the top of the pressure tube 604. The top of the vertical rod 15 passes through the filter cylinder 602 and is fixedly connected to a push plate 16.

A cooler 17 is installed through the bottom of the cooling box 603 to cool the coolant. Cooling treatment is performed to ensure the cooling effect. A liquid pump 18 is connected to one side of the cooling box 603 to pump the coolant to the processing area. The outlet of the liquid pump 18 is connected to the delivery pipe 19 to spray the coolant directly onto the drill bit 3 and the workpiece. A drain pipe 20 is connected to one side of the pressure pipe 604 to discharge the filtered clean coolant. A sliding groove is opened on one side of the filter cylinder 602 to facilitate the installation and movement of the pressure pipe 604. A limit plate 21 is fixedly connected to the surface of the impact rod 502 to limit the movement range of the impact rod 502. A second spring is sleeved on the surface of the impact rod 502 to provide quick reset after impact, ensuring the continuous operation of the vibration component 5.

[0041] The working principle of this invention is as follows: the operator places the lead screw seat to be processed on the top of the support grid 22, then moves the clamping plate to fix the lead screw seat, and then starts the drilling and milling machine body 2 to drive the drill bit 3 to cut the workpiece. At the same time as cutting, the liquid pump 18 is started, and the liquid pump 18 draws out the coolant in the cooling tank 603 and rushes it to the drill bit 3 and the workpiece through the delivery pipe 19 to cool the drill bit 3.

[0042] The debris generated during rinsing flows downwards with the coolant and enters the collection shell 403. Large particles of impurities are filtered through the filter screen 404 inside the collection shell 403. Because the oil is relatively viscous, the natural sedimentation filtration speed is slow. At this point, the drive motor 701 can be started. The drive motor 701, in conjunction with the rotating shaft 702, drives the first pulley 708 to rotate. The first pulley 708, in conjunction with the second pulley 709, drives the support shaft 707 to rotate the turntable 706. The turntable 706, in conjunction with the connecting shaft 705, pushes the adjusting rod 704 to move. The adjusting rod 704, in conjunction with the fixed... The fixed shaft 703 drives the moving plate 501 to move, and the moving plate 501 drives the collecting shell 403 to move back and forth, improving the fluidity of the oil and increasing the filtration effect. While the moving plate 501 moves, it drives the push rod 503 to move. At this time, the convex plate 504 pushes the push rod 503. When the push rod 503 moves, it squeezes the first spring. When the push rod 503 continues to move, the first spring can reset the push rod 503. The push rod 503 drives the impact rod 502 to strike the collecting shell 403, increasing the speed of the oil passing through the filter screen 404 through vibration.

[0043] The filtered oil flows downwards and enters the conveying shell 8. The rotating shaft 702 rotates, simultaneously driving the first synchronous pulley 9 to rotate. The first synchronous pulley 9, in conjunction with the second synchronous pulley 13, drives the synchronous belt 10 to rotate. The synchronous belt 10 drives the infusion shell 11 to reciprocate, conveying the initially filtered oil upwards to the filter shell and through a pipe into the filter cylinder 602. As the second synchronous pulley 13 rotates with the synchronous belt 10, it drives the auxiliary rod 12 to rotate. The auxiliary rod 12 drives the cam 14 to rotate. When the cam 14 rotates, it pushes the push plate 16 and the vertical rod 15. When the vertical rod 15 moves downwards, it drives the pressure tube 604 and the filter element 605 to move downwards. At this time, the oil is under pressure and can seep upwards, passing through the filter element 605 for secondary filtration, further improving the filtration effect. At this point, the cooler 17 is activated to cool the oil, allowing the coolant to be reused.

[0044] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. 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.
