Description

Technical Field

[0001] This utility model relates to the field of milling machine equipment technology, and in particular to a milling machine with a protective structure. Background Technology

[0002] A milling machine is a machine tool that uses a high-speed rotating multi-bladed milling cutter to cut workpieces. It can perform machining of planes, grooves, gears, threads and complex curved surfaces. It has the characteristics of multi-bladed intermittent cutting and its production efficiency is higher than that of a planer. It is widely used in mechanical manufacturing, mold processing, aerospace and other fields, and is one of the core equipment for achieving high-precision and diversified machining in modern industry.

[0003] In the existing open machining mode of vertical milling machines, there is a lack of protective plates. During machining, high-speed flying metal chips expose operators to a dangerous environment. The flying chips can easily hit vulnerable areas such as the face and eyes, causing serious injuries such as cuts, punctures, or even blindness. These hazards seriously threaten the health and safety of operators. Therefore, a milling machine with a protective structure is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing vertical milling machines in open machining mode, which lack protective plates and expose operators to dangerous environments due to high-speed flying metal chips during machining. These flying chips can easily hit vulnerable areas such as the face and eyes, causing serious injuries such as cuts, punctures, or even blindness. These hazards seriously threaten the health and safety of operators. Therefore, this invention proposes a milling machine with a protective structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A milling machine with a protective structure includes a milling machine and a transparent protective plate. A support frame is rotatably connected to the milling machine. Two sets of fixing components for fixing the transparent protective plate are provided on the support frame. The fixing components include pins provided at the ends of the support frame and fixing blocks provided on both sides of the milling machine. A protective frame is slidably connected to the outside of the support frame. Two sets of adjusting components for adjusting the transparent protective plate are provided on the protective frame. The adjusting components include adjusting rods inserted and connected to the outside of the protective frame and multiple adjusting slots opened on both sides of the support frame.

[0007] The above technical solution further includes:

[0008] The transparent protective plates are in multiple sets and are located in front of and on the left and right sides of the parts being machined on the milling machine. The distribution of the transparent protective plates prevents the debris generated by the parts being machined on the milling machine from flying everywhere.

[0009] Both sides of the milling machine are fixedly connected to a fixing rod, and two limiting blocks are installed on the fixing rod. The fixing rod and the fixing block are fixedly connected. Two slots are opened on the side of the fixing block. The two slots are arranged at a 90-degree angle with the axis of the fixing rod as the center. The transparent protective plates of the two slots are positioned at different positions on the milling machine.

[0010] The fixing component also includes a rotating block fixedly connected to the end of the support frame. The rotating block is installed between two limiting blocks and is connected through the fixing block. The pin is inserted into the rotating block and a pull rod is fixedly installed at one end of the pin. The other end of the pin is inserted into the slot at the corresponding position. A limiting ring is installed on the pin and a first return spring is fixedly connected to it. The end of the first return spring away from the limiting ring is fixedly connected to the rotating block. The pin can be easily pulled by the pull rod at the end of the pin.

[0011] A limiting rod is fixedly connected to the side of the rotating block. The end of the limiting rod has a groove to facilitate the placement of the pull rod at the end of the pin. The groove on the limiting rod is used to fix the pin at the top by placing the pull rod.

[0012] The support frame has convex sliding grooves on both sides, and the adjustment groove is connected to the convex sliding groove. The protective frame has convex sliders fixedly connected symmetrically on its side, and the convex sliders are slidably connected to the convex sliding groove. The protective frame is fixedly connected to the transparent protective plate. The protective frame has handles fixedly connected symmetrically on its side. The protective frame and the support frame are connected through the convex sliding groove and the convex slider.

[0013] The adjustment assembly also includes a housing fixedly connected to the side of the protective frame. A second return spring is fixedly connected inside the housing. The second return spring is fixedly connected to the adjustment rod. A pull plate is fixedly connected to the end of the adjustment rod. The end of the adjustment rod away from the pull plate is located inside the adjustment groove at the corresponding position. By fixing the adjustment rod to multiple adjustment grooves, the position of the transparent protective plate can be adjusted.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the rotating block and the fixed block in the fixing component are connected through the fixed component, and the pin and slot are precisely inserted to achieve a stable fixation. The design of the pull rod and the limit rod makes the pulling and positioning of the pin easy and convenient. The first return spring ensures that the pin automatically returns to its original position, enhancing the fixing effect. This design not only allows the transparent protective plate to be quickly and accurately positioned in different positions on the milling machine, effectively preventing the splashing of machining chips and ensuring the safety of the operator, but also makes it easy to flexibly adjust the position of the protective plate when changing workpieces. The operation is simple and efficient, greatly improving the safety and convenience of using the milling machine.

[0016] 2. In this utility model, the adjusting rod is disengaged from the adjusting groove by the pull plate in the adjusting assembly. With the elastic action of the second return spring, the transparent protective plate can be easily moved and precisely positioned on the support frame. For workpieces of different heights and lengths, the operator can quickly adjust the position of the transparent protective plate to ensure that it can effectively block the splashing of processing debris, protect the operator's safety, and not hinder the placement and processing of the workpiece. The design of multiple adjusting grooves further enhances the accuracy and flexibility of the adjustment, meets diverse processing needs, and greatly improves the applicability and ease of operation of the milling machine.

[0025] like Figures 1-7As shown, the present invention proposes a milling machine with a protective structure, including a milling machine 1 and a transparent protective plate 2. A support frame 4 is rotatably connected to the milling machine 1. The support frame 4 is provided with two sets of fixing components for fixing the transparent protective plate 2. The fixing components include pins 10 provided at the ends of the support frame 4 and fixing blocks 6 provided on both sides of the milling machine 1. A protective frame 3 is slidably connected to the outside of the support frame 4. The protective frame 3 is provided with two sets of adjusting components for adjusting the transparent protective plate 2. The adjusting components include adjusting rods 16 inserted and connected to the outside of the protective frame 3 and multiple adjusting slots 12 opened on both sides of the support frame 4.

[0026] There are multiple sets of transparent protective plates 2, which are located in front of and on the left and right sides of the workpiece being machined on the milling machine 1. The distribution of the transparent protective plates 2 prevents the debris generated by the workpiece being machined on the milling machine 1 from flying everywhere.

[0027] Both sides of the milling machine 1 are fixedly connected to a fixing rod 5. Two limit blocks are installed on the fixing rod 5. The fixing rod 5 is fixedly connected to the fixing block 6. Two slots 8 are opened on the side of the fixing block 6. The two slots 8 are arranged at a 90-degree angle with the axis of the fixing rod 5 as the center. The two slots 8 are respectively positioned at different positions on the milling machine 1 for the transparent protective plate 2.

[0028] The fixing component also includes a rotating block 7 fixedly connected to the end of the support frame 4. The rotating block 7 is installed between two limiting blocks and is connected through the fixing block 6. A pin 10 is inserted into the rotating block 7 and a pull rod is fixedly installed at one end of the pin 10. The other end of the pin 10 is inserted into the slot at the corresponding position. A limiting ring is installed on the pin 10 and a first return spring 11 is fixedly connected to it. The end of the first return spring 11 away from the limiting ring is fixedly connected to the rotating block 7. The pin 10 can be easily pulled by the pull rod at the end of the pin 10.

[0029] A limiting rod 9 is fixedly connected to the side of the rotating block 7. The end of the limiting rod 9 is provided with a groove to facilitate the placement of the pull rod at the end of the pin 10. The groove on the limiting rod 9 is used to fix the pin 10 on the top by placing the pull rod.

[0030] The support frame 4 has convex grooves 13 on both sides, and the adjustment groove 12 is connected to the convex groove 13. The protective frame 3 has convex sliders 14 fixedly connected to its side, and the convex sliders 14 are slidably connected to the convex grooves 13. The protective frame 3 is fixedly connected to the transparent protective plate 2. The protective frame 3 has handles fixedly connected to its side. The protective frame 3 and the support frame 4 are connected through the convex grooves 13 and the convex sliders 14.

[0031] The adjustment assembly also includes a housing 15 fixedly connected to the side of the protective frame 3. A second return spring 17 is fixedly connected inside the housing 15. The second return spring 17 is fixedly connected to the adjustment rod 16. A pull plate is fixedly connected to the end of the adjustment rod 16. The end of the adjustment rod 16 away from the pull plate is located inside the adjustment groove 12 at the corresponding position. By fixing the adjustment rod 16 to multiple adjustment grooves 12, the position of the transparent protective plate 2 can be adjusted.

[0032] In this embodiment, the milling machine 1 processes the workpiece. By pulling the pull rod at the end of the pin 10 outward with a finger, the other end of the pin 10 is disengaged from the slot 8. The pull rod at the end of the pin 10 is then slightly rotated with a finger, causing it to be placed in the groove at the end of the limiting rod 9. At this point, the other side of the pin 10 is pulled according to the above description. The support frame 4 and the transparent protective plate 2 are now in a disengaged state. By dragging the protective frame 3, the support frame 4 drives the rotating block 7 to rotate on the fixed rod 5, placing the transparent protective plate 2 in front of and on both sides of the milling machine's processing component. At this point, the ends of the pins 10 on both sides can be... The pull rod disengages from the groove at the end of the limit rod 9 and is compressed. The first return spring 11 rebounds and the pin 10 is fixed in the slot 8 above the fixing block 6, thus fixing the transparent protective plate 2. The transparent protective plate 2 surrounds and protects the milling machine part. When it is necessary to change to other workpieces for processing, as described above, the pin 10 is pulled to release the fixing effect of the pin 10. The transparent protective plate 2 is then rotated by hand to be located above the milling machine 1 and fixed in the slot 8 on one side of the fixing block 6 by the pin 10. In this way, the transparent protective plate 2 is fixed above the milling machine 1 and does not hinder the change of workpieces on the milling machine 1.

[0033] Secondly, when the workpiece to be processed is long and tall, the small area covered by the transparent protective plate 2 will restrict the workpiece. At this time, by grasping the handles on both sides of the protective frame 3 with both hands, and pinching the pull plate at the end of the adjusting rod 16 with two fingers, the pull plate is pulled outward with two fingers to make the pull plate drive the adjusting rod 16 out of the adjusting groove 12. Then, by moving the handles upward with both hands, the handles drive the protective frame 3 and the transparent protective plate 2 to move on the support frame 4. When it moves to the appropriate position, the pull plate is released, and the second return spring 17, which is compressed, rebounds and fixes the adjusting rod 16 on the adjusting groove 12. This fixes the adjusted position of the transparent protective plate 2, so as not to hinder the placement of the workpiece on the milling machine 1 and the processing limitation. Moreover, the height of the workpiece can be adjusted according to the height of the workpiece through multiple adjusting grooves 12.
