Technical Field

[0001] The utility model belongs to the technical field of milling machines, and particularly relates to a milling machine. Background Art

[0002] A milling machine is a common metal processing machine tool used for cutting and surface processing of workpieces. The milling machine is widely used in fields such as mold manufacturing, machining, and component processing, and can achieve high-precision and good machining performance;

[0003] The workpiece to be processed is clamped on the workbench to ensure that the workpiece is stable and does not move. Subsequently, the spindle drives the milling cutter to perform cutting on the workpiece. During actual operation, a large amount of metal chips will be generated during the cutting of the workpiece by the milling cutter. The metal chips are splashed randomly, causing environmental pollution around and posing certain safety hazards to the staff. Moreover, it is necessary to remove the workpiece after processing is completed before placing the next workpiece. And due to the influence of the chips, it is necessary to clean the chips on and around the fixture before placing a new workpiece. Therefore, it will seriously affect the effective working time of the milling machine and result in low processing efficiency. Summary of the Utility Model

Support carrier disks are fixedly connected to both sides of the rotating disk. Both support carrier disks are rotatably connected to the top end of the support bed body. Protective boxes are fixedly connected to the top ends of both rotating disks. A lifting plate is slidably connected to the inner wall of the protective box. Fixtures are arranged at the top ends of both lifting plates. The fixture includes a concave plate and a clamping plate.

DETAILED DESCRIPTION

[0017] See also Figures 1-4, the present utility model provides the following technical solutions: It includes a support bed body 1, a milling cutter 13, and a driving motor 14. A lifting pillar 11 is slidably connected to the inner wall of the support bed body 1. A support plate 12 is slidably connected to one side of the lifting pillar 11. The driving motor 14 is installed at the bottom of the support plate 12. A rotating disk 2 is rotatably connected to the top end of the support bed body 1. Support carrier disks 21 are fixedly connected to both sides of the rotating disk 2. Both of the two support carrier disks 21 are rotatably connected to the top end of the support bed body 1. Protective boxes 3 are fixedly connected to the top ends of the two rotating disks 2. A lifting plate 31 is slidably connected to the inner wall of the protective box 3. Clamps 4 are arranged at the top ends of the two lifting plates 31. The clamp 4 includes a concave plate 41 and a clamping plate 42. The concave plate 41 is installed at the top end of the corresponding lifting plate 31. The clamping plate 42 is slidably connected to the top end of the concave plate 41. The two concave plates 41 alternately rotate to the position below the milling cutter 13.

[0018] In this implementation: The support bed 1 supports each component of the device. The lifting strut 11 slides on the inner wall of the support bed 1, so that the lifting strut 11 drives the support plate 12 to complete lifting and lowering. The support plate 12 supports the drive motor 14, and the drive motor 14 supports and drives the milling cutter 13, enabling the milling cutter 13 to complete rotary cutting work. The rotating disk 2 is driven to rotate by the internal motor of the support bed 1. The rotating disk 2 drives the two support carriers 21 to rotate. The support carriers 21 support and rotate the corresponding protective boxes 3. The two support carriers 21 alternately rotate below the milling cutter 13, so that the two support carriers 21 can drive the corresponding protective boxes 3 to alternately rotate below the milling cutter 13 to participate in the processing operation. The protective box 3 supports and slides the corresponding lifting plate 31. The lifting plate 31 supports the corresponding concave plate 41. The fixture 4 uses the concave plate 41 and the clamping plate 42 to clamp and fix the workpiece. The telescopic device inside the concave plate 41 pushes the clamping plate 42, so that the two clamping plates 42 can approach each other to realize the clamping and fixing work of the workpiece. After the workpiece to be processed is placed on the concave plate 41 and fixed, control the rotating disk 2 to rotate. The rotating disk 2 drives the two support carriers 21 to rotate. The two support carriers 21 drive the corresponding protective boxes 3 to rotate. The protective box 3 drives the concave plate 41 to rotate through the lifting plate 31. The concave plate 41 drives the workpiece to rotate to the position below the milling cutter 13. Subsequently, control the lifting strut 11 and the lifting plate 31 to slide downward, so that the lifting plate 31 can drive the concave plate 41 and the workpiece to descend into the interior of the protective box 3. The support plate 12 drives the drive motor 14 and the milling cutter 13 to slide downward, so that the milling cutter 13 can machine the workpiece. At this time, the side walls around the protective box 3 shield the workpiece inside, so that the metal chips generated when the milling cutter 13 cuts the workpiece can be shielded by the protective box 3, reducing the situation of metal chips splashing to the outside, thereby reducing the environmental pollution around and reducing the safety hazards to the staff. Subsequently, rotate and transfer the processed workpiece to a station away from the milling cutter 13, and transfer another workpiece to below the milling cutter 13 to continue processing. At this time, the transferred protective box 3 facilitates the removal and replacement of the workpiece inside, and at the same time cleans the metal chips on the protective box 3, the lifting plate 31 and the concave plate 41, so that the effective processing time of the device is increased and the processing work efficiency is improved.

[0019] The inner wall of the support plate 12 is rotatably connected with a first lead screw 121 and a guide rod 122. The inner wall of the support plate 12 is slidably connected with a slide rail 15. The slide rail 15 is threadedly connected to the side wall of the first lead screw 121. The slide rail 15 is slidably connected to the side wall of the guide rod 122. The driving motor 14 is slidably connected to the inner wall of the slide rail 15. The inner wall of the slide rail 15 is rotatably connected with a second lead screw 151. The second lead screw 151 is threadedly connected to the inner wall of the driving motor 14. The first lead screw 121 drives the slide rail 15, enabling the slide rail 15 to slide. The guide rod 122 guides and limits the sliding of the slide rail 15, preventing the slide rail 15 from falling off and experiencing movement deviation. The slide rail 15 is connected to the top of the driving motor 14 by a connection set of the second lead screw 151. Both the second lead screw 151 and the first lead screw 121 are controlled to rotate by corresponding motor sets. The second lead screw 151 can drive the driving motor 14 to slide. Through the driving of the first lead screw 121 and the second lead screw 151, the driving motor 14 and the milling cutter 13 can be transferred to different processing stations. Moreover, the support plate 12 is lifted and lowered by a telescopic machine inside the lifting pillar 11, improving the flexibility during the processing of the milling cutter 13.

[0020] Four return springs 32 are fixedly connected to the bottom end of the lifting plate 31. The four return springs 32 are all fixedly connected to the inner wall of the corresponding protective box 3. When processing the workpiece, the lifting plate 31 is pressed down. The lifting plate 31 compresses the four return springs 32 downward and shortens them. The return springs 32 support the lifting plate 31. When the downward pressing action on the lifting plate 31 is released, the four return springs 32 can push the lifting plate 31 to lift and return to its original position, facilitating the response to the next processing operation. Moreover, after the lifting plate 31 is lifted, it is convenient to lift the remaining metal chips for easy cleaning.

[0021] Four limiting rods 33 are fixedly connected to the inner wall of the protective box 3. The four limiting rods 33 penetrate the top end of the corresponding lifting plate 31. The lifting plate 31 is slidably connected to the side wall of the corresponding limiting rod 33. The return spring 32 is sleeved on the side wall of the corresponding limiting rod 33. The limiting rods 33 guide and limit the up and down sliding of the lifting plate 31, preventing the lifting plate 31 from detaching and experiencing movement deviation. The limiting rods 33 support the inside of the return spring 32, preventing the return spring 32 from being overly compressed and bent, which would affect its own elasticity.

[0022] A pressure plate 111 is fixedly connected to one side of the lifting pillar 11, and a clearance gap 34 is opened on one side of the two protection boxes 3. The pressure plate 111 is slidably connected to the inner wall of the clearance gap 34, and the pressure plate 111 is in contact with the top of the two lifting plates 31; the pressure plate 111 will not contact the rotating protection box 3, and the lifting pillar 11 supports and drives the pressure plate 111. When the lifting pillar 11 slides downward, it drives the pressure plate 111 to slide down, and the pressure plate 111 is in contact with the top of the lifting plate 31. At the same time, the lifting plate 31 enters the corresponding clearance gap 34. The protection box 3 uses the clearance gap 34 to make way for the pressure plate 111, so that the pressure plate 111 can lower the height of the lifting plate 31, which is convenient for the workpiece to descend into the protection box 3 for processing.

[0023] The working principle and use process of the utility model are as follows: when the device is used, when the workpiece to be processed is placed on the concave plate 41, after the workpiece is fixed by two clamping plates 42, the rotating disk 2 is controlled to rotate, and the rotating disk 2 drives the two supporting carriers 21 to rotate, and the two supporting carriers 21 drive the corresponding protective box 3 to rotate, and the protective box 3 drives the concave plate 41 to rotate through the lifting plate 31, and the concave plate 41 drives the workpiece to rotate to the position below the milling cutter 13, and then the lifting pillar 11 is controlled to drive the pressing plate 111 and the supporting plate 12 to descend, and the pressing plate 111 contacts the top of the lifting plate 31, and at the same time, the lifting plate 31 enters the corresponding clearance notch 34, and the protective box 3 uses the clearance notch 34 to make way for the pressing plate 111, so that the pressing plate 111 can lower the height of the lifting plate 31, so that the lifting plate 31 can drive the concave plate 41 and the workpiece to descend. Enter the interior of the protective box 3. At this time, the side walls of the protective box 3 shield the workpiece inside, so that the metal debris generated by the milling cutter 13 when cutting the workpiece can be shielded by the protective box 3, reducing the occurrence of metal debris splashing to the outside, thereby reducing the pollution to the surrounding environment and reducing the safety hazards to the staff. The rotating disk 2 is controlled to rotate, and the rotating disk 2 drives the two supporting carriers 21 to rotate. The two supporting carriers 21 drive the corresponding protective box 3 to rotate, so that the new workpiece can be transferred to the processing area under the milling cutter 13 in time. At this time, the transferred protective box 3 is convenient for taking out and replacing the workpiece inside, and at the same time, the metal debris on the protective box 3, the lifting plate 31 and the concave plate 41 are cleaned, thereby increasing the effective processing time of the device and improving the processing efficiency.
