Description

Technical Field

[0001] The invention relates to the field of milling machine processing, in particular to a cleaning and feeding device for a milling machine. Background Art

[0002] Milling machines mainly refer to machine tools that use milling cutters to process various surfaces of workpieces. Usually, the main motion is the rotation of the milling cutter, and the movement of the workpiece and the milling cutter is the feed motion. It can process planes, grooves, various curved surfaces, gears, etc. Milling machines are machine tools that use milling cutters to mill workpieces.

In addition, it can also be used for processing the surface of a rotating body, inner holes and cutting. When the milling machine is working, the workpiece is mounted on a workbench or an accessory such as a dividing head. The rotation of the milling cutter is the main motion, supplemented by the feed motion of the workbench or milling head, so that the workpiece can obtain the required processing surface.

[0041] The milling machine cleaning and loading device of the present invention will be described in more detail below with reference to the schematic diagrams, in which the preferred embodiments of the present invention are shown. It should be understood that those skilled in the art can modify the present invention described herein while still achieving the advantageous effects of the present invention. Therefore, the following description should be understood as a broad guidance for those skilled in the art and not as a limitation to the present invention.

[0042] In the following paragraphs, the present invention will be described more specifically by way of example with reference to the accompanying drawings. The advantages and features of the present invention will be clearer according to the following description and the claims. It should be noted that the drawings are all in a very simplified form and use non-precise scales, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0043] Embodiment 1:

[0044] As Figure 1 shown, the embodiment of the present invention provides a milling machine cleaning and loading device, including an installation back plate 1, a flipping traveling table, a vibration loading part and an air flow cleaning part.

[0045] Specifically, the flipping traveling table is rotatably installed on the installation back plate 1, and an angle adjusting part is arranged between the flipping traveling table and the installation back plate 1, and the angle adjusting part is used to adjust the flipping angle of the flipping traveling table.

[0046] The vibration loading part is installed on the flipping traveling table. The vibration loading part contacts the workpiece to be processed through the flipping of the flipping traveling table, and performs multi-point vibration compaction on the workpiece to be processed through the traveling of the flipping traveling table.

[0047] The air flow cleaning member is installed on the flipping and traveling table. The air flow cleaning member moves through the flipping and traveling table and blows off debris on the surface of the positioning groove of the workpiece to be processed.

[0048] In this embodiment, the mounting back plate 1 is installed on the inner wall of the milling machine opposite to the movable door. Before the workpiece to be processed is placed in the positioning groove of the milling machine, the angle adjusting member drives the flipping and traveling table to rotate so that the flipping and traveling table is in a horizontal state. At this time, the flipping and traveling table enters the working state. The flipping and traveling table drives the air flow cleaning member to move, and the air flow cleaning member blows off all the debris in the positioning groove of the milling machine during the movement, avoiding the debris from lifting the workpiece to be processed and causing the surface of the workpiece to be processed to be in a non-horizontal state, thereby ensuring the processing quality of the workpiece to be processed.

[0049] It should be noted that during the process of the workpiece to be processed being processed and taken out, the air flow cleaning member can cooperate with the flipping and traveling table to automatically blow off the debris in the positioning groove of the workpiece to be processed, without the need for subsequent manual blowing off of the debris in the positioning groove of the workpiece to be processed, thus greatly improving the processing efficiency of the milling machine.

[0050] Further, two hidden installation grooves 2 are symmetrically formed on the mounting back plate 1, and the angle adjusting member is arranged in the hidden installation groove 2.

[0051] Specifically, the angle adjusting member adopts an electric telescopic rod 3. One end of the electric telescopic rod 3 is rotatably installed in the hidden installation groove 2, and the other end of the electric telescopic rod 3 is rotatably connected to the flipping and traveling table.

[0052] In this embodiment, the flipping and traveling table has a storage state and a working state. When the electric telescopic rod 3 is in a fully contracted state, the upper surface of the flipping and traveling table is completely attached to the mounting back plate 1, and the flipping and traveling table is in the storage state. At this time, the flipping and traveling table does not affect the lifting movement and horizontal movement of the milling cutter of the milling machine, so that the milling groove operation can be performed on the workpiece to be processed.

[0053] When the electric contraction rod is in a fully extended state, the flipping and traveling table is in a horizontal state, and the flipping and traveling table enters the working state. At this time, the flipping and traveling table can drive the vibrating loading member and the air flow cleaning member to move, thereby realizing the blowing off operation of the debris in the positioning groove of the workpiece to be processed and realizing the compaction and fitting between the workpiece to be processed and the inner wall of the positioning groove, thereby improving the processing quality of the workpiece to be processed.

[0054] Further, the flipping and traveling table includes a fixed table 4, a traveling table 5, a driving lead screw 6, and a driving motor 7.

[0055] Specifically, the fixed table 4 is rotatably installed on the mounting back plate 1, and the fixed table 4 is rotatably connected to the electric telescopic rod 3.

[0056] The traveling table 5 is slidably arranged on the fixed table 4 along the length direction of the fixed table 4.

[0057] The driving lead screw 6 is rotatably installed on the fixed table 4, and the driving lead screw 6 is in threaded connection with the traveling table 5.

[0058] The driving motor 7 is fixedly installed on the fixed table 4, and the output end of the driving motor 7 is in transmission connection with the driving lead screw 6.

[0059] In this embodiment, when it is necessary to blow debris from the positioning groove of the workpiece to be processed or perform a compaction and fitting operation on the workpiece to be processed, the driving motor 7 is turned on. Driven by the driving motor 7, the driving lead screw 6 rotates. Due to the limiting effect of the fixed table 4 on the traveling table 5 which is in threaded connection with the driving lead screw 6, the traveling table 5 can only drive the vibrating loading member and the air flow purging member to move along the length direction of the driving lead screw 6, thereby realizing the full purge operation of the positioning groove of the workpiece to be processed and the full compaction and fitting operation of the workpiece to be processed.

[0060] In a specific embodiment, the driving lead screw 6 adopts a reciprocating lead screw. A reciprocating lead screw is a lead screw that can make the slider perform reciprocating motion without changing the rotation direction of the main shaft. It is a form of solid cam pair, manifested as two thread grooves with the same pitch and opposite helix directions, and the two ends are connected by transition curves. Through the rotation of the lead screw, the side of the helical groove pushes the slider placed in the helical groove to perform axial reciprocating motion. In this solution, the reciprocating lead screw is adopted, and the reciprocating movement of the traveling table 5 can be realized through the single-direction drive of the driving motor 7.

[0061] In addition, the driving motor 7 adopts a servo motor. A servo motor is a motor that can accurately control its position, speed and acceleration under the guidance of a control signal. It converts electrical energy into mechanical energy and drives the load to move along a preset trajectory. The working principle of the servo motor is based on a closed-loop control system, and it drives the load to move by receiving the command signal from the controller. In this solution, the driving motor 7 is adopted, which can accurately control the angular displacement of the driving lead screw 6, so as to accurately control the moving distance of the traveling table 5.

[0062] It should be noted that an activity groove 8 is formed in the bottom surface of the fixed table 4 along its length direction, and the traveling table 5 is slidably arranged in the activity groove 8. Driven by the driving motor 7, the traveling table 5 can move along the length direction of the driving lead screw 6.

[0063] Furthermore, the vibrating loading member includes an elastic telescopic frame, a vibration motor 9 and a transmission roller 10.

[0064] Specifically, the elastic telescopic frame is fixedly installed on the traveling table 5, and the elastic telescopic frame has an elastic space in the vertical direction.

[0065] The vibration motor 9 is fixedly installed on the elastic telescopic frame, and the vibration motor 9 is used to provide a vibration source.

[0066] The transmission roller 10 is rotatably installed on the elastic telescopic frame, and the transmission roller 10 is used to transfer the vibration energy of the vibration motor 9 to the workpiece to be processed.

[0067] Wherein, the elastic telescopic frame includes a mounting plate 11, a vibration spring 12 and a vibration table 13. The mounting plate 11 is fixedly installed on the traveling table 5. The vibration table 13 is elastically connected to the mounting plate 11 through the vibration spring 12. A telescopic tube is arranged inside the vibration spring 12, and both ends of the telescopic tube are fixedly connected to the mounting plate 11 and the vibration table 13 respectively.

[0068] In addition, the telescopic tube includes an inner tube 14 and an outer tube 15. The inner tube 14 is slidably connected to the outer tube 15. One end of the inner tube 14 away from the outer tube 15 is fixedly connected to the mounting plate 11, and one end of the outer tube 15 away from the inner tube 14 is fixedly connected to the vibration table 13.

[0069] When it is necessary to perform a compaction and fitting operation on the workpiece to be processed, the vibration motor 9 starts to work. The vibration generated by the vibration motor 9 is transmitted to the workpiece to be processed through the transmission roller 10, and then the workpiece to be processed is compacted and fitted into the positioning groove. When the workpiece to be processed is completely compacted and fitted into the positioning groove, the surface of the workpiece to be processed is in a horizontal state, avoiding the decline of processing quality caused by the inclination of the surface of the workpiece to be processed.

[0070] In addition, the flipping traveling table can drive the transmission roller 10 to move along the surface of the workpiece to be processed, and thus can realize the comprehensive compaction and fitting operation of the workpiece to be processed, thereby ensuring the overall horizontal state of the surface of the workpiece to be processed and greatly improving the processing quality of the milling machine.

[0071] Furthermore, the air flow cleaning member includes an air duct groove 16 and an air flow cleaning window 17.

[0072] Specifically, the air duct groove 16 is fixedly installed on the traveling table 5. The air duct groove 16 has a gas cavity 18, and the gas cavity 18 is connected to an air compressor (not shown in the figure) through a pipeline.

[0073] The air flow cleaning window 17 is inclinedly arranged on the air duct groove 16, and the air flow cleaning window 17 is communicated with the gas cavity 18.

[0074] In this embodiment, when it is necessary to blow off debris from the positioning groove of the workpiece to be processed, the traveling table 5 drives the air duct groove 16 to move. At the same time, the compressed air generated by the air compressor is discharged through the air flow cleaning window 17, which can blow off the debris in the positioning groove of the workpiece to be processed, thus avoiding the influence of debris on the placement of the workpiece to be processed and ensuring the machining quality of the milling machine.

[0075] Among them, the air flow cleaning window 17 is arranged in an inclined shape, which can blow off the debris in the positioning groove of the workpiece to be processed in one direction. In addition, in order to ensure that the debris in the positioning groove can be blown off comprehensively, the number of reciprocating movements of the traveling table 5 can be set, such as reciprocating 2 times, 3 times...

[0076] It should be noted that the transmission roller 10 is exposed outside the air flow cleaning window 17. When blowing off debris from the positioning groove of the workpiece to be processed, the transmission roller 10 contacts the bottom surface of the positioning groove, and at the same time, the air flow blows off the debris in the positioning groove. In addition, as Figure 2 shown, when the flipping traveling table is in the storage state, the structure perpendicular to the fixed table and closest to the milling machine movable door is the transmission roller 10. In the storage state, the transmission roller 10 does not affect the movement of the milling cutter of the milling machine, ensuring the normal operation of the milling machine.

[0077] Embodiment 2:

[0078] The present invention also discloses a method for cleaning and loading a milling machine, including the following steps:

[0079] S100. The electric telescopic rod 3 extends, so that the flipping traveling table enters the working state. At the same time, the driving motor 7 is turned on, and the air duct groove 16 performs a comprehensive debris blowing operation on the positioning groove of the workpiece to be processed under the drive of the driving motor 7.

[0080] S200. Place the workpiece to be processed into the positioning groove, turn on the driving motor 7 and the vibration motor 9. At this time, the transmission roller 10 moves along the surface of the workpiece to be processed, and at the same time, the vibration of the transmission roller 10 is used to press the workpiece to be processed against the positioning groove.

[0081] S300. The electric telescopic rod 3 contracts, and the flipping traveling table is in the storage state. The milling machine processes the workpiece to be processed located in the positioning groove.

[0082] S400. After the workpiece to be processed is processed, take out the workpiece to be processed located in the positioning groove, and repeat the above steps.

[0083] Compared with the prior art, the present invention has at least the following beneficial effects:

[0084] The present invention uses an angle adjustment member to change the flipping angle of the flipping and traveling table, enabling the adjustment of the flipping and traveling table in the storage state and the working state. In the storage state, the flipping and traveling table does not interfere with the operation of the milling cutter, ensuring the normal operation of the milling machine.

[0085] Furthermore, through angle flipping, the flipping and traveling table can enable the vibration loading member and the air flow cleaning member to work in cooperation with the workpiece to be processed. On the one hand, it can automatically and comprehensively clean the debris in the positioning groove of the workpiece to be processed, improving the processing efficiency of the milling machine. On the other hand, it can also compact the workpiece to be processed flat in the positioning groove through vibration, avoiding the milling groove operation when the workpiece to be processed is in an inclined state, and ensuring the processing quality of the milling machine.

[0086] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these changes and modifications.
