[0029] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions in the present utility model will be clearly and completely described below with reference to the accompanying drawings in the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without making creative efforts based on the embodiments in the present utility model belong to the scope of protection of the present utility model.

[0030] The following combines Figures 1 to 2 to describe the chip conveyor system of the machine tool of the present utility model.

[0031] As Figures 1 to 2 shown, the chip conveyor system provided in the embodiment of the present utility model is arranged on the bed body 1 of the machine tool. A workbench device 2 and a driving device are arranged on the bed body 1. The workbench device 2 slides reciprocally in the longitudinal direction, and the driving device is used to drive the workbench device 2 to slide reciprocally.

[0032] For the convenience of description, the direction in which the workbench device 2 slides relative to the bed body 1 is defined as the longitudinal direction. Referring to Figure 1 the direction indicated by y in Figure 1 , the longitudinal direction is arranged horizontally; the transverse direction is arranged horizontally and is perpendicular to the longitudinal direction. The transverse direction refers to Figure 1 the direction indicated by x in

[0033] The chip conveyor system provided in this embodiment includes a chip leakage opening 3, a pair of protective covers and a chip conveyor 4.

[0034] The chip leakage opening 3 is arranged on the bed body 1. The chip leakage opening 3 is located below the workbench device 2. The projection area of the workbench device 2 in the vertical direction is located inside the projection area of the chip leakage opening 3 in the vertical direction.

[0035] The chip leakage opening 3 extends longitudinally from one end of the bed body 1 to the other end of the bed body 1. When the workbench device 2 works at any position in the longitudinal direction, the generated chips can smoothly enter the chip leakage opening 3, reducing the conduction of chips inside the machine tool, shortening the chip removal time of the machine tool, and improving the chip removal efficiency of the machine tool.

[0036] A pair of protective covers are arranged on the bed body 1, and the two of the pair of protective covers are respectively located on the two transverse sides of the workbench device 2. The protective covers can block the chips generated during the workpiece processing, so that the splashing chips can smoothly enter the chip leakage opening 3.

[0037] The chip receiving end of the chip conveyor 4 extends below the chip leakage port 3. The chip conveyor 4 is used to receive the chips at the chip leakage port 3 and transport the chips away from the chip leakage port 3.

[0038] With such an arrangement, the chip leakage port 3 is vertically aligned with the workbench device 2, and the opening size of the chip leakage port 3 is increased. Combined with the setting of the protective cover, it can effectively ensure that the chips generated during the workpiece processing smoothly enter the chip leakage port 3 and fall onto the chip receiving end of the chip conveyor 4, so that the chip conveyor 4 can timely and effectively transport the chips away, solving the problems of poor chip removal and easy chip accumulation in the existing machine tools.

[0039] It should be noted that the machine tool chip removal system provided in this embodiment can be applied to, but is not limited to, three-axis machine tools, five-axis machine tools, etc.

[0040] In the embodiment of the present utility model, the chip leakage port 3 has at least a pair of inclined side walls 5, and the pair of inclined side walls 5 are distributed transversely.

[0041] Among the two vertical ends of the inclined side wall 5, the one closer to the workbench device 2 is the first end, and the one farther from the workbench device 2 is the second end. The distance between the first ends of the pair of inclined side walls 5 is greater than the distance between the second ends of the pair of inclined side walls 5.

[0042] The inclined side wall 5 has the function of guiding. During the workpiece processing, chips are generated and will slide down along the inclined side wall 5 after falling onto the inclined side wall 5, avoiding the retention of chips on the side wall of the chip leakage port 3.

[0043] Among the side walls of the chip leakage port 3, the two distributed longitudinally are arranged vertically.

[0044] A cross beam 10 is provided on the bed 1 of the machine tool. The cross beam 10 has a gantry structure and is fixedly connected to the bed 1. The cross beam 10 is used to set the machine head. The wall surface of the cross beam 10 facing the workbench device 2 is also arranged vertically.

[0045] In this embodiment, the protective cover includes a first cover body 6 and a second cover body 7. Both the first cover body 6 and the second cover body 7 are arranged on the bed 1. The first cover body 6 and the second cover body 7 are respectively located on both longitudinal sides of the workbench device 2. The first cover body 6 and the second cover body 7 are connected to the workbench device 2, and both the first cover body 6 and the second cover body 7 are linked with the workbench device 2, so that the protective cover can adapt to the longitudinal sliding of the workbench device 2, avoiding the generation of gaps between the first cover body 6 and the workbench device 2 and between the second cover body 7 and the workbench device 2 during the sliding process of the workbench device 2, and avoiding chips from splashing out between the first cover body 6 and the workbench device 2 and between the second cover body 7 and the workbench device 2.

[0046] In this embodiment, the first cover 6 and the second cover 7 are arranged in a structural form with a telescopically adjustable longitudinal length.

[0047] The first end of the first cover 6 in the longitudinal direction is fixedly connected to the bed body 1, and the second end of the first cover 6 in the longitudinal direction is connected to the workbench device 2. The first end of the second cover 7 in the longitudinal direction is fixedly connected to the bed body 1, and the second end of the second cover 7 in the longitudinal direction is connected to the workbench device 2.

[0048] That is to say, the first ends of the first cover 6 and the second cover 7 are both relatively fixed to the bed body 1, and the second ends of the first cover 6 and the second cover 7 are both relatively fixed to the workbench device 2. When the workbench device 2 slides longitudinally, it drives the second ends of the first cover 6 and the second cover 7 to displace longitudinally, and the positions of the first ends of the first cover 6 and the second cover 7 on the bed body 1 remain fixed, thereby realizing the telescoping of the first cover 6 and the second cover 7.

[0049] With such an arrangement, when the workbench device 2 slides to any position in the longitudinal direction, the protective cover can provide effective protection, and the protection effect is comprehensive.

[0050] It should be noted that the second end of the first cover 6 fits the surface of the workbench device 2 to avoid forming a gap between the second end of the first cover 6 and the workbench device 2, thereby preventing chips from splashing out from this gap. Similarly, the second end of the second cover 7 fits the surface of the workbench device 2 to avoid forming a gap between the second end of the second cover 7 and the workbench device 2, thereby preventing chips from splashing out from this gap.

[0051] In this embodiment, an armor protective cover is selected as the first cover 6 and the second cover 7.

[0052] In this embodiment, both the first cover 6 and the second cover 7 include a first vertical portion, an inclined portion, and a second vertical portion. The first vertical portion, the inclined portion, and the second vertical portion are connected in sequence in the direction away from the bed body 1. One end of the first vertical portion is connected to the chip leakage port 3. Refer to Figure 1 .

[0053] Among the two vertical ends of the inclined portion, the one farther from the bed body 1 is the first end, and the one farther from the bed body 1 is the second end. The distance between the first ends of the inclined portions of a pair of protective covers is greater than the distance between the second ends of the inclined portions of a pair of protective covers.

[0054] The inclined portion has a guiding function. During the workpiece processing, chips are generated and will slide downward along the inclined portion after falling onto the inclined portion, avoiding the retention of chips on the protective cover.

[0055] In the embodiment of the utility model, the workbench device 2 spans across the chip leakage opening 3 in the horizontal direction, and the two lateral ends of the workbench device 2 are respectively slidably connected to the bed 1. The driving device includes a pair of driving mechanisms 8, and the driving mechanisms 8 are arranged on the bed 1, and the pair of driving mechanisms 8 are distributed on both sides of the chip leakage opening 3 in the horizontal direction. Two of the pair of driving mechanisms 8 act on the two lateral ends of the workbench device 2 respectively, and the two ends of the workbench device 2 are driven by a pair of driving mechanisms 8, which can improve the stability of the workbench device 2 and help reduce the driving force requirements of the driving mechanism 8. Moreover, while ensuring the stability of the workbench device 2, the driving device is kept away from the middle position of the bed 1 as much as possible, so as to increase the lateral size of the chip leakage opening 3 as much as possible, and ensure that the chips smoothly enter the chip leakage opening 3 and are smoothly discharged.

[0056] In this embodiment, a pair of guide rails 9 are arranged between the workbench device 2 and the bed 1, the axis of the guide rails 9 is arranged longitudinally, and the pair of guide rails 9 are distributed transversely on both sides of the chip leakage opening 3. The pair of guide rails 9 guide the two ends of the workbench device 2 to ensure the smooth sliding of the workbench device 2.

[0057] The first vertical parts of a pair of protective covers are located between a pair of guide rails 9 and between a pair of driving mechanisms 8. The setting of the inclined parts allows a side of the pair of protective covers to be separated from each other to form an escape space for avoiding the guide rails 9 and the driving mechanisms 8, thereby ensuring as much space as possible between the pair of protective covers.

[0058] The driving mechanism 8 can be, but is not limited to, configured as a screw-nut transmission structure or a gear rack transmission structure.

[0059] To sum up, the machine tool chip removal system provided by the embodiment of the utility model can avoid the splashing of chips, and effectively ensure that the chips generated during the workpiece processing enter the chip leakage port 3 smoothly, quickly and efficiently, and fall to the chip receiving end of the chip conveyor 4, so that the chips can be transported away in a timely and effective manner by relying on the chip conveyor 4, effectively solving the problem of poor chip removal and easy chip accumulation in machine tools in the prior art.

[0060] On the other hand, the embodiment of the utility model further provides a machine tool, including the machine tool chip removal system provided by any of the above embodiments. The machine tool chip removal system provided by the above embodiments can timely and effectively remove chips and avoid the problem of chip accumulation. Therefore, the machine tool provided by this embodiment has the advantages of smooth chip removal and guaranteed processing accuracy. The derivation process of the beneficial effects of the machine tool in the embodiment of the utility model is generally similar to the derivation process of the beneficial effects of the above machine tool chip removal system, so it will not be repeated here.

[0061] The machine tool provided in this embodiment may be, but is not limited to, a three-axis machine tool, a five-axis machine tool, etc.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
