DETAILED DESCRIPTION

[0023] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0024] Embodiment: Please refer to Figures 1 to 4 According to the embodiment of the present application, a technical scheme is provided: a numerical control gantry precision milling machine for processing a flat knitting machine base, comprising: a machine tool 1, a sliding groove 2 is formed in the machine tool 1; a workbench mechanism; it slides in the sliding groove 2, the workbench mechanism comprises a table body 3, an inclined plate 4, a permanent magnet suction cup 5, a gear 6, a limiting wheel 7, a rotating rod 8, a rack 9, an electric push rod 10 and a lead screw motor 22, the table body 3 is hollow inside and the rotating rod 8 is rotatably connected inside, the inclined plate 4 is fixed with the rotating rod 8, the rotating rod 8 protrudes from both ends of the table body 3 and is fixed with the gear 6, the rack 9 is engaged with the gear 6, the electric push rod 10 drives the rack 9 to rotate the gear 6, the limiting wheel 7 is fixed at both ends of the rotating rod 8 and embedded in the table body 3, the permanent magnet suction cup 5 is fixed at the top of the inclined plate 4, and the lead screw motor 22 is installed on the machine tool 1 and drives the table body 3 to slide in the sliding groove 2; a numerical control precision milling group is fixedly installed on both sides of the sliding groove 2 of the machine tool 1, and the numerical control precision milling group comprises a Y-shaped support 11, a mounting plate 12, a milling cutter 13 and a driving push rod 14, the mounting plate 12 is fixed on the inclined side of the support 11, the milling cutter 13 is slidably connected to the mounting plate 12, and the driving push rod 14 is fixedly installed on the mounting plate 12 and pushes the milling cutter 13 to move in the direction of the table body 3.

[0025] The numerical control gantry precision milling machine with the above structure can prevent the permanent magnet suction cup 5 on the inclined plate 4 from moving when the flat knitting machine base to be processed needs to be processed, the movement of the flat knitting machine base to be processed is limited by the permanent magnet suction cup 5, the next step is that the lead screw motor 22 drives the table body 3 to move in the direction of the numerical control precision milling group, when it is located below the numerical control precision milling group, the driving push rod 14 in the numerical control precision milling group drives the milling cutter 13 to cut the flat knitting machine base to be processed, when the flat knitting machine base to be processed needs to be drilled, the electric push rod 10 drives the rack 9 to rotate the gear 6 and the rotating rod 8, drives the inclined plate 4 fixed with the rotating rod 8 to incline, until the inclined plate 4 is perpendicular to the milling cutter 13, then the driving push rod 14 drives the milling cutter 13 to drill, a standard round hole can be drilled, and the problem that the inclined driving mechanism, the bed straight linear guide and the workbench sliding table cannot be inclined, can only move up and down or left and right, and it is difficult to keep the flat knitting machine base perpendicular to the milling cutter 13, making it difficult to process the round hole, is solved.

[0026] In order to adjust the distance between the two milling cutters 13 on the same side of the sliding groove 2 and adjacent to each other at will, so as to meet various processing requirements and improve the processing efficiency, a plurality of first sliding rods 16 are arranged between the supports 11, and a connecting plate 15 is slidably connected with the first sliding rods 16. At this time, the mounting plate 12, the milling cutter 13 and the driving push rod one 14 installed on the connecting plate 15 can slide on the first sliding rod 16 through the connecting plate 15. Then, the driving push rod two 17 driven by the support 11 to move the connecting plate 15 on the first sliding rod 16 can drive the adjustment of the distance between the two milling cutters 13, so as to meet different processing requirements and improve the processing efficiency.

[0027] In order to increase the stability of the mounting plate 12 during sliding, a plurality of inclined second sliding rods 18 are arranged on the connecting plate 15, and the mounting plate 12 is slidably connected with the second sliding rods 18. The driving push rod one 14 can drive the milling cutter 13 to move on the second sliding rod 18 in the direction of the machine tool 1. A plurality of inclined second sliding rods 18 are arranged on the connecting plate 15. The second sliding rod 18 has the same effect as the guide rail, which provides guidance and support for the movement of the mounting plate 12. In this way, during the machining process, the milling cutter 13 can more accurately mill the horizontal machine base, which helps to improve the machining quality and precision.

[0028] If the gear 6 is exposed to the working environment for a long time, the surrounding sundries (such as chips, dust, etc.) are easy to enter the meshing part between the teeth of the gear 6. The half-toothed structure and the gap are not higher than the inclined plate 4, which reduces the space that the sundries can enter and reduces the risk of interference of the sundries with the normal meshing of the gear 6. The rack 9 can drive the gear 6 to rotate 90°.

[0029] By fixing the limiting rod 19 on both sides of the length direction of the machine tool 1 located in the sliding groove 2, the table body 3 is slidably connected with the limiting rod 19, and the sliding block 20 is fixedly installed at the bottom of the table body 3. The sliding block 20 is embedded and slidably connected at the bottom of the sliding groove 2 of the machine tool 1. The limiting rod 19 provides additional guidance and constraint for the sliding of the table body 3, preventing the table body 3 from shaking or deviating left and right (relative to the length direction of the sliding groove 2) during sliding, preventing the milling position from deviating and affecting the machining quality. At the same time, the sliding block 20 at the bottom of the table body 3 can further enhance the stability of the sliding of the table body 3, so that the table body 3 slides more stably in the sliding groove 2.

[0030] The auxiliary rotating rod 21 is arranged on both sides of the rotating rod 8, and the inclined plate 4 is fixed with the two auxiliary rotating rods 21, which adds an additional support point for the rotation of the inclined plate 4. When the inclined plate 4 rotates, only relying on the rotating rod 8 may shake or be unstable due to uneven force or other factors, and the auxiliary rotating rod 21 shares the load of the rotation of the inclined plate 4, so that the rotation of the inclined plate 4 is more stable.

[0031] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
