Description

Technical Field

[0001] The utility model relates to the technical field of gantry machine tools, in particular to a chip removal structure for gantry machine tools. Background Art

[0002] Gantry machine tools are milling machines with a portal frame and a long horizontal bed. Gantry machine tools can use multiple milling cutters to process surfaces at the same time, with high processing accuracy and production efficiency. They are suitable for processing the planes and inclined surfaces of large workpieces in batch and mass production, and are therefore widely used.

[0003] The CNC gantry machine tool can also process spatial surfaces and some special parts. During the processing, the waste chips usually fall into the chip grooves on both sides of the machine tool, and then are collected by the chip grooves. The chip grooves on both sides are used to make the waste chips fall to the bottom. However, due to the long bed of the gantry machine tool, the length of the chip groove is relatively long, so the landing point of the waste chips directly discharged by the chip groove is relatively long. The generated waste chips cannot be discharged at a fixed point, resulting in inconvenient chip removal and not conducive to the treatment of waste chips. For this reason, we proposed a chip removal structure for gantry machine tools. Utility Model Content

[0004] The utility model provides a chip removal structure for a gantry machine tool, which solves the problems raised by the above-mentioned background technology.

[0009] Optionally, the support frame is located directly above the conveying strip, and one end of the conveying strip is fixedly connected to a rotating wheel, and the rotating wheel is movably mounted on the machine tool bed.

[0010] Optionally, a transmission belt is commonly sleeved between the rotating wheels, and a driving motor is fixedly connected inside the machine tool bed, and the output shaft of the driving motor is connected to one of the rotating wheels to drive the transmission belt to rotate.

[0011] The utility model has the following beneficial effects:

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 6 A chip removal structure for a gantry machine tool comprises a machine tool bed 1, and chip removal grooves 2 are provided on both sides of the top of the machine tool bed 1. Waste chips are removed through the chip removal grooves 2. Both sides of the bottom of the inner cavity of the chip removal groove 2 are gradually inclined toward the middle. Under the inclined structure of the chip removal groove 2, the waste chips falling on the chip removal groove 2 can slide smoothly to the middle, and the chip removal groove 2 comprises blocking plates 7 on both sides. Under the shielding of the blocking plates 7, the waste chips falling on the chip removal groove 2 can be blocked by the blocking plates 7 when they are splashed, so that the splashed waste chips can fall back into the chip removal groove 2. The top of the blocking plate 7 is in an inner arc shape, so that the splashed waste chips can be blocked by the blocking plates 7. When the chips are blocked, they can fall back into the chip groove 2 again along the inner arc trajectory, effectively preventing the waste chips from splashing out. The inner arc at the top of the baffle plate 7 is facing the middle of the chip groove 2. At the same time, a semicircular groove is opened in the middle of the chip groove 2. The waste chips falling on the chip groove 2 finally slide into the semicircular groove. The semicircular groove is provided with a spiral conveying strip 4 in contact with the inner wall of the semicircular groove. Under the rotation of the conveying strip 4, the waste chips in the semicircular groove can be pushed into the chip collecting groove 5, and then the chips are concentratedly removed. A chip collecting groove 5 is opened at one end of the machine tool bed 1, and one end of the conveying strip 4 extends into the chip collecting groove 5, so that the waste chips can be smoothly conveyed to the chip collecting groove 5.

[0023] See also Figures 1 to 5 The chip collecting groove 5 is connected to one end of the chip discharge groove 2, so that the waste chips in the chip discharge groove 2 can be smoothly transported to the chip collecting groove 5, and the bottom of the inner cavity of the chip collecting groove 5 gradually tilts toward the middle, so that the waste chips falling into the chip collecting groove 5 can slide toward the middle of the bottom of the inner cavity of the chip collecting groove 5, and a circular chip outlet 6 is opened in the middle of the bottom of the inner cavity of the chip collecting groove 5, and the waste chips sliding to the middle of the bottom of the inner cavity of the chip collecting groove 5 are finally discharged through the chip outlet 6.

[0024] See also Figures 1 to 6A plurality of cylindrical support columns 12 are fixed on the two inclined surfaces at the bottom of the inner cavity of the chip groove 2. The use of cylindrical support columns 12 can effectively reduce the waste chips sliding down the chip groove 2 and being blocked by the support columns 12. The top ends of the support columns 12 are connected to a cylindrical connecting frame 3 through bolts. The use of the cylindrical connecting frame 3 allows the fallen waste chips to pass through the connecting frame 3 more smoothly and fall onto the chip groove 2.

[0025] See also Figures 1 to 6 A plurality of support frames 11 in a triangular structure are fixedly connected between the connecting frames 3, so that the supporting force of the support frames 11 is more stable, and under the action of the connecting frames 3 and the support frames 11, the conveying strips 4 can be protected. One corner of the triangular structure of the support frames 11 is vertically upward, and the support frames 11 are arranged at intervals, so that the waste chips can smoothly fall through the support frames 11.

[0026] See also Figures 1 to 5 The support frame 11 is located directly above the conveying strip 4, and one end of the conveying strip 4 is fixedly connected to a rotating wheel 8. Driven by the rotating wheel 8, the conveying strip 4 can rotate. The rotating wheel 8 is movably mounted on the machine tool bed 1, and the rotating wheel 8 can be rotated at a fixed position on the machine tool bed 1.

[0027] See also Figures 1 to 5 A transmission belt 9 is commonly sleeved between the rotating wheels 8. Under the drive of the transmission belt 9, the rotating wheels 8 can rotate together, and a driving motor 10 is fixedly connected to the inside of the machine tool bed 1. The output shaft of the driving motor 10 is connected to one of the rotating wheels 8 to drive the transmission belt 9 to rotate. Under the drive of the output shaft of the driving motor 10, the rotating wheel 8 can rotate. The driving motor 10 is a prior art and will not be described in detail here.

[0028] In summary, the gantry machine tool uses a chip removal structure. When the chip removal structure is working, the waste chips generated by the gantry machine tool fall into the chip groove 2, and can slide into the semicircular groove under the action of the inclined structure of the chip groove 2, and when the waste chips fall into the chip groove 2, they may collide and splash to the outside. At this time, under the action of the blocking plate 7, the waste chips can be blocked, so that the waste chips can fall into the chip groove 2 smoothly. Driven by the output shaft of the driving motor 10, the rotating wheel 8 can rotate, and under the drive of the transmission belt 9, the two rotating wheels 8 can rotate. Driven by the rotating wheel 8, the conveying strip 4 can rotate, and then under the rotation and conveying of the conveying strip 4, the waste chips in the semicircular groove can be transported to the chip collecting groove 5, and then under the inclined structure of the chip collecting groove 5, the waste chips can be concentrated and discharged through the chip outlet 6.
