Technical Field

[0001] This utility model relates to the field of boring and milling machine technology, specifically a floor-type boring and milling machine equipped with a longitudinal positioning component. Background Technology

[0002] A floor-type boring and milling machine is a heavy-duty machine tool mainly used for boring and milling large workpieces. It typically fixes large workpieces on a floor platform for processing, hence the name floor-type boring and milling machine. Floor-type boring and milling machines have sufficient power and rigidity to meet the requirements of heavy-duty milling and are suitable for heavy machinery manufacturing plants and other similar applications.

[0003] When machining large workpieces, current floor-type boring and milling machines suffer from longitudinal dimensional changes caused by thermal deformation or clamping stress, which reduces the stability of the workpiece top and decreases the machining accuracy. Therefore, there is an urgent need for a floor-type boring and milling machine that can perform longitudinal positioning of the workpiece. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a floor-type boring and milling machine equipped with a longitudinal positioning component, which has the advantages of ensuring the stability of the workpiece top and high machining accuracy, thus solving the problems mentioned in the background technology.

The support platform 601 can drive the slide table 3 to move horizontally by driving the support platform 601 through the hydraulic cylinder 5.

[0025] In this embodiment, preferably, the limiting component 8 includes a lifting plate 801 and a pressure plate 804. A plurality of lifting rods 803 are fixedly mounted on the top of the lifting plate 801. The pressure plate 804 is slidably connected to the lifting rods 803.

A four-jaw chuck 807 is fixedly mounted on the center of the bottom of the lifting plate 801. A pressure sensor 802 is fixedly mounted on the center of the top of the lifting plate 801. The pressure sensor 802 is located between the pressure plate 804 and the lifting plate 801. Slide grooves 806 are provided on both sides of the lifting plate 801. The support 7 has slide grooves 806 on both sides. The inner wall is fixedly equipped with guide rails 15.

The inspection grooves 10 can ensure the operating space, which is convenient for disassembling and repairing the hydraulic cylinder 5 and the support assembly 6.

[0027] In use, the workpiece is first placed on the slide table 3, and then the bottom of the workpiece is limited by the four-jaw chuck 4. When the size of the workpiece is high, the lifting plate 801 of the limiting component 8 is driven to descend by the hydraulic cylinder 9. The guide rail 15 can guide the lifting plate 801 through the slide groove 806, which can reduce the height of the four-jaw chuck 807. The top of the workpiece can be fixed by the four-jaw chuck 807.

[0029] During the workpiece machining process, the four-jaw chuck 14 and the four-jaw chuck 2807 limit the two ends of the workpiece respectively, increasing the fulcrum of the workpiece, maintaining the stability of the two ends of the longitudinal direction of the workpiece, improving the machining accuracy of the workpiece, and reducing the longitudinal dimensional changes of the workpiece caused by its own thermal deformation or clamping stress.

[0030] After the workpiece is processed, the control slide 3 is reset, the four-jaw chuck 1 4 and four-jaw chuck 2 807 are released, and the pressure plate 804 is lifted vertically to remove the workpiece. Since the lifting rod 803 is slidably connected to the pressure plate 804, the pressure sensor 802 is prevented from bearing tension.
