Description

Technical Field

[0001] This utility model relates to the field of gantry milling machine technology, and in particular to a fixed table type precision planar milling machine. Background Technology

[0002] A gantry milling machine, also known as a gantry milling machine, is a milling machine with a gantry frame and a horizontal long bed. In a milling machine, the milling cutter usually rotates as the main motion, while the movement of the workpiece and the milling cutter is the feed motion. It can process planes, grooves, as well as various curved surfaces, gears, etc. A milling machine is a machine tool that uses a milling cutter to mill workpieces. In addition to milling planes, grooves, gear teeth, threads, and splined shafts, milling machines can also process relatively complex profiles. They are more efficient than planers and are widely used in mechanical manufacturing and repair departments. A search of existing Chinese patent technology reveals a "gantry milling machine frame" with publication number "CN221088055U". This device fixes the parts during the processing to prevent the position of the parts from changing due to the vibration generated by drilling, which could lead to processing errors. However, during the cutting process, the movement and vibration of the processing table can cause dimensional errors, and the subsequent grinding process takes a long time, affecting the efficiency of steel processing.

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.

[0017] The following is combined with Figures 1-6 This invention describes a fixed-table precision planar milling machine.

[0018] In one embodiment, a fixed benchtop precision planar milling machine includes: a machining frame 1, a support frame 2 fixedly connected to the upper end of the machining frame 1, and a plurality of guide rails 21 fixedly connected to the surface of the support frame 2; and a stabilizing mechanism 3, which is mounted on the surface of the machining frame 1 and extends to the upper end of the support frame 2. The stabilizing mechanism 3 includes a milling cutter moving assembly 31 mounted on the surface of the support frame 2. The surface of the milling cutter moving assembly 31 is in contact with the surface of the guide rail 21. A positioning assembly 33 is provided below the milling cutter moving assembly 31. The positioning assembly 33 is mounted on the surface of the processing frame 1. A cleaning assembly 32 is provided between the milling cutter moving assembly 31 and the positioning assembly 33. The cleaning assembly 32 is mounted on the inner side of the processing frame 1. like Figure 1-4 As shown, the milling cutter moving assembly 31 includes a first motor 311 fixedly connected to the inner side of the support frame 2. The output shaft of the first motor 311 is fixedly connected to a threaded shaft 312. The threaded shaft 312 is rotatably connected to the inner wall of the support frame 2. A connecting threaded sleeve 313 is threadedly connected to the surface of the threaded shaft 312. A moving frame 314 is fixedly connected to the side of the connecting threaded sleeve 313 away from the support frame 2. The longitudinal section of the moving frame 314 is similar to an L-shape. A traveling milling cutter 316 is connected to the side of the moving frame 314 away from the threaded shaft 312. A plurality of sliding seats 315 are fixedly connected to the side of the moving frame 314 away from the traveling milling cutter 316. The sliding seats 315 are slidably connected to the surface of the adjacent guide rail 21. In this embodiment, the inner sliding seat 315 of the movable frame 314 slides on the surface of multiple guide rails 21. Under the action of the multiple guide rails 21, the stability of the movable frame 314 carrying the traveling milling cutter 316 is improved. The traveling milling cutter 316 can move longitudinally in the vertical plane of the movable frame 314, so that the first motor 311 drives the threaded shaft 312 to rotate synchronously, and then connects the threaded sleeve 313 to drive the movable frame 314 to move along the axis of the threaded shaft 312. This reduces the large errors in the material caused by the motion processing of the device; reduces the amount of grinding in subsequent processing, saves the processing time of the steel plate, and greatly improves efficiency. like Figure 2 , Figure 5 and Figure 6 As shown, the positioning component 33 includes an electromagnetic base 331 fixedly connected to the surface of the processing frame 1. Two movable slides 332 are opened at the upper end of the electromagnetic base 331. Two fixing blocks 333 are fixedly connected to the inner wall of the movable slides 332. A bidirectional threaded rod 334 is rotatably connected to the inner wall of the fixing blocks 333. Two fixing threaded sleeves 336 are threadedly connected to the surface of the bidirectional threaded rod 334. A clamping block 335 is fixedly connected to the surface of the fixing threaded sleeves 336. The clamping block 335 is slidably connected to the inner wall of the movable slides 332. The upper end of the clamping block 335 extends above the electromagnetic base 331. In this embodiment, the device, through the electromagnetic base 331, can be connected to an external electromagnetic device to magnetically attract the steel to be processed. The clamping block 335 positions the material to be processed. The rotation of the bidirectional threaded rod 334 causes the fixed threaded sleeve 336 to drive the clamping block 335 to slide along the inner wall of the moving slide 332, thus maintaining good clamping effect on the processed material, ensuring material stability, and reducing large errors during material processing. The structure is more stable, the error in processing steel plates is smaller, the amount of grinding in subsequent processes is reduced, the processing time of the steel plate is saved, and efficiency is greatly improved. The impurity removal assembly 32 includes a guide trough 321 fixedly connected to the inner side of the processing frame 1. A second motor 322 is fixedly connected to one end of the guide trough 321. An auger shaft 323 is fixedly connected to the output shaft of the second motor 322. The auger shaft 323 is rotatably connected to the inner wall of the guide trough 321. In this embodiment, the second motor 322 drives the auger shaft 323 to rotate on the inner wall of the guide trough 321, so that the iron filings are automatically discharged into the iron frame, saving manpower and time for manual cleaning of iron filings and making the processing environment around the machine tool cleaner and tidier.

[0019] Working principle: The inner sliding seat 315 of the moving frame 314 slides on the surface of multiple guide rails 21. Under the action of multiple guide rails 21, the stability of the moving frame 314 carrying the traveling milling cutter 316 is improved. The traveling milling cutter 316 moves longitudinally in the vertical plane of the moving frame 314. The first motor 311 drives the threaded shaft 312 to rotate synchronously. The connecting threaded sleeve 313 drives the moving frame 314 to move along the axis of the threaded shaft 312. The clamping block 335 positions the material to be processed. The rotation of the bidirectional threaded rod 334 causes the fixed threaded sleeve 336 to drive the clamping block 335 to rotate on the inner wall of the moving slide 332, reducing the occurrence of large errors in the material processing process.

[0020] It should be noted that the first motor 311 and the second motor 322 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the first motor 311 and the second motor 322 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0021] 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.
