Description

Technical Field

[0001] The invention relates to the field of CNC machine tool bases, and in particular to a CNC machine tool base structure. Background Art

[0002] CNC machine tools are machine tools that use computer programs to control the automated processing process. It uses digital codes to control the movement of the machine tool to achieve precise control of the shape, size and position of the workpiece. CNC machine tools are widely used in aerospace, automobile manufacturing, mold manufacturing, precision instrument manufacturing and other fields, and are indispensable key equipment in modern manufacturing.

[0003] In the process of machining metal parts, the lathe tool performs cutting, drilling and other actions on the surface of the metal parts. A large amount of heat is generated in the process, and the tool and the workpiece need to be cooled and lubricated by cutting fluid. At the same time, a large amount of metal chips are generated. The base of the CNC machine tool will contain a drainage hole to facilitate the discharge of metal chips and cutting fluid. Metal chips flow through the drainage hole and block the drainage hole. In the prior art, it is generally adopted to add a shaking mechanism near the drainage hole, and the metal chips are gradually shaken off from the drainage hole by the shaking mechanism, or by setting a drainage hole with a variable aperture, so as to expand the aperture of the drainage hole so that the metal chips can pass through the drainage hole. However, some metal chips are in the shape of spiral strips, and their length can even reach the decimeter level, and their spiral diameter can reach several centimeters. Multiple hollow, long, spiral metal chips are very easy to entangle with each other and block the drainage hole, which requires manual regular cleaning.

[0004] The purpose of the present invention is to design a CNC machine tool base structure in view of the above-mentioned problems in the prior art. Summary of the invention

[0005] In view of the problems existing in the above-mentioned prior art, the present invention provides a CNC machine tool base structure, which can effectively solve at least one problem existing in the above-mentioned prior art.

[0006] The technical solution of the present invention is:

[0007] A CNC machine tool base structure, comprising:

[0008] A base body, wherein the base body is provided with a plurality of drainage holes;

[0009] A squeezing mechanism is arranged at the drainage hole, and the squeezing mechanism includes an annular airbag, the outer ring of which is fixedly connected to the inner wall of the drainage hole, the annular airbag is inflated or deflated by an external air pump, and a plurality of fixing rods are arranged at equal angles on the inner ring of the annular airbag. After the annular airbag is inflated, the inner diameter of the annular airbag becomes smaller, driving the fixing rods to move closer to the center of the annular airbag, thereby squeezing the metal chips;

[0010] A winding mechanism is arranged below the extrusion mechanism, and the winding mechanism includes a rotating clamping finger cylinder, and the rotating clamping finger cylinder is used to clamp the extruded metal chips and then rotate, so that the extruded metal chips are wound around the clamping fingers of the rotating clamping finger cylinder;

[0011] The disengaging mechanism is arranged below the winding mechanism and is used for clamping and disengaging the metal chips wound on the winding mechanism.

[0012] Furthermore, the winding mechanism includes a first driving cylinder, which is arranged on the base body. The first driving cylinder drives the rotating finger cylinder to move up and down. After the first driving cylinder drives the rotating finger cylinder to move up, the rotating finger cylinder is close to the bottom surface of the extrusion mechanism.

[0013] Furthermore, the detachment mechanism includes a second driving cylinder, which is laterally arranged on the base body. A hook is arranged at the telescopic end of the second driving cylinder. After the first driving cylinder drives the rotating finger cylinder to move downward, the second driving cylinder drives the hook to contract, thereby detaching the metal chips wrapped around the rotating finger cylinder.

[0014] Furthermore, it includes a bellows, which is arranged below the drainage hole, the fingers of the rotating clamping finger cylinder are inserted into the bellows, and the first driving cylinder is arranged outside the bellows. When the first driving cylinder drives the rotating clamping finger cylinder to move up and down, the bellows is driven to expand and contract.

[0015] Furthermore, a flow sensor is arranged in the bellows.

[0016] Furthermore, the control method of the CNC machine tool base structure is:

[0017] S1, controlling the extrusion mechanism to extrude metal chips;

[0018] S2, controlling the first driving cylinder to drive the rotating clamping finger cylinder to move upward, and controlling the rotating clamping finger cylinder to clamp the extruded metal chips;

[0019] S3, controlling the rotating clamp finger cylinder to maintain the clamping state and rotate to a certain angle;

[0020] S4, cyclically executing S1 and S3 for several times, so that the metal chips are squeezed and wound around the rotating clamp finger cylinder;

[0021] S5, control the first driving cylinder to drive the rotating finger cylinder to move downward to below the second driving cylinder, control the second driving cylinder to extend the hook, control the first driving cylinder to drive the rotating finger cylinder to move upward so that the metal chips are clamped by the hook, and control the second driving cylinder to retract the hook to remove the metal chips wrapped around the rotating finger cylinder.

[0022] Therefore, the present invention provides the following effects and / or advantages:

[0023] The present application is optimized based on the characteristics of metal chips that are hollow, long, and have a spiral structure. The metal chips are squeezed by an extrusion mechanism to become an elongated structure, thereby initially reducing the space occupied by the metal chips. The metal chips are then wound by a winding mechanism to form a roll or a ball, thereby further reducing the space occupied by the metal chips, making it less likely for the metal chips to block the drainage hole or the space below the drainage hole, and becoming easier to discharge. Finally, the metal chips are removed by a removal mechanism to be discharged from the drainage hole.

[0024] The present invention achieves the clamping and rotation of metal chips by rotating the clamping finger cylinder, and finally achieves the winding action. The present invention inflates the annular airbag, so that the central aperture of the airbag becomes smaller after the airbag expands, forming an action similar to human hand holding, and the metal chips are tightly grasped to form a slender structure.

[0025] The present application can realize the detachment action through the cooperation of the first driving cylinder and the second driving cylinder.

[0026] Other features and advantages of the present invention will be described in the following description, and partly become apparent from the description, or understood by practicing the present invention. The purpose and other advantages of the present invention are realized and obtained by the structures particularly pointed out in the description and the drawings.

[0032] Base body 1, drainage hole 101, squeezing mechanism 2, annular airbag 201, fixing rod 202, winding mechanism 3, rotating clamping finger cylinder 301, first driving cylinder 302, detaching mechanism 4, second driving cylinder 401, hook 402, bellows 5, flow sensor 6. DETAILED DESCRIPTION

[0033] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the accompanying drawings:

[0034] refer to Figure 1-3 , A CNC machine tool base structure, comprising:

[0035] A base body 1, wherein the base body is provided with a plurality of drainage holes 101;

[0036] In this embodiment, an inclined surface is disposed at the upper end of the base body 1 , and the drainage hole 101 is disposed at the lower part of the inclined surface.

[0037] The squeezing mechanism 2 is arranged at the drainage hole 101, and the squeezing mechanism 2 is used to change the inner diameter of the drainage hole 101 so as to squeeze the metal chips. In this embodiment, after the squeezing mechanism 2 is opened, the inner diameter of the drainage hole 101 becomes larger, which can facilitate the passage of chip liquid, metal chips, etc.; after the squeezing mechanism 2 is closed, the inner diameter of the drainage hole 101 becomes smaller, and the squeezing mechanism 2 squeezes the metal chips. Since the metal chips are hollow and spiral in structure, they occupy a large space, and it is easy for multiple or single metal chips to entangle with each other and block the drainage hole 101. After the metal chips are squeezed by the squeezing mechanism 2, the part of the metal chips located at the squeezing mechanism 2 is squeezed and gathered at the center of the squeezing mechanism 2, and the space occupied by the metal chips is greatly reduced, while forming a slender structure that is easy to fold.

[0038] The winding mechanism 3 is arranged below the extrusion mechanism 2, and the winding mechanism 3 receives the extruded metal chips and winds them into a ball or roll; since the metal chips are in the shape of long strips, a part of them easily enters the drainage hole 101, while the rest is located above the drainage hole 101, thus forming a situation where it is difficult to pass through the drainage hole 101. In this embodiment, in the above, the metal chips are extruded into a slender structure by the extrusion mechanism 2, and the metal chips extruded into the shape of long and thin strips are received and clamped by the winding mechanism 3, and are wound into a ball or roll, so that the metal chips in the shape of long and thin strips are gathered into a ball or roll. On the one hand, the metal chips located above the drainage hole 101 can be dragged into the bottom of the drainage hole 101, and on the other hand, the metal chips can be wound and gathered into a ball or roll with a more compact structure, so that they can easily pass through the space below the drainage hole 101 and be discharged out of the base body 1.

[0039] The disengaging mechanism 4 is arranged below the winding mechanism 3 , and is used for clamping and disengaging the metal chips wound on the winding mechanism 3 .

[0040] In this embodiment, it is mentioned above that the winding mechanism 3 winds the metal chips and gathers them into a more compact ball or roll. At this time, the detaching mechanism 4 is required to separate the rolled or balled metal chips from the winding mechanism 3 so that the separated metal chips can be discharged from the base body 1 along with the cutting fluid.

[0041] In this embodiment, the metal chips are optimized for their hollow, long, spiral structure. The metal chips are squeezed, wound, and detached, thereby squeezing and winding them, which greatly reduces the space occupied by the metal chips and makes them easier to discharge.

[0042] Furthermore, the extrusion mechanism 2 includes an annular airbag 201, the outer ring of which is fixedly connected to the inner wall of the drainage hole 101. The annular airbag 201 is inflated or deflated by an external air pump. After inflation, the inner diameter of the annular airbag 201 becomes smaller, thereby squeezing metal chips.

[0043] In this embodiment, after the annular airbag 201 is inflated, since the outer ring of the annular airbag 201 is fixedly connected to the inner wall of the drainage hole 101, the drainage hole 101 limits the diameter change of the outer ring of the annular airbag 201, and the inner ring of the annular airbag 201 converges to its center after inflation, thereby being able to squeeze metal chips.

[0044] Furthermore, a plurality of fixing rods 202 are arranged at equal angles in the inner circle of the annular airbag 201 . The inflated annular airbag 201 drives the fixing rods 202 to move toward the center of the annular airbag 201 , thereby squeezing metal chips.

[0045] In this embodiment, the center of the annular airbag 201 drives the fixed rod 202 to move, and the fixed rod 202 is located in the inner circle of the annular airbag 201, so that the metal chips are squeezed through the fixed rod 202. On the one hand, the fixed rod 202 has higher rigidity and is easier to squeeze the metal chips. On the other hand, the mechanism formed by the fixed rod 202 can further reduce the space in the middle position of the annular airbag 201 after restarting, so that the metal chips can be squeezed more thoroughly.

[0046] Furthermore, the winding mechanism 3 includes a rotating clamping finger cylinder 301 , which is used to clamp the squeezed metal chips and then rotate, so that the squeezed metal chips are wound around the clamping fingers of the rotating clamping finger cylinder 301 .

[0047] Furthermore, the winding mechanism 3 includes a first driving cylinder 302, which is arranged on the base body. The first driving cylinder 302 drives the rotating finger clamping cylinder 301 to move up and down. After the first driving cylinder 302 drives the rotating finger clamping cylinder 301 to move upward, the rotating finger clamping cylinder 301 is close to the bottom surface of the extrusion mechanism 2.

[0048] In this embodiment, the rotating clamping finger cylinder 301 is directly adopted from the prior art, which can realize the action of clamping and rotating. Through the clamping action of the rotating clamping finger cylinder 301, one end of the metal chips can be clamped, and then the rotating clamping finger cylinder 301 rotates, so that the metal chips are wrapped around the clamping fingers of the rotating clamping finger cylinder 301, and the metal chips are wrapped to form a multi-ring structure. The length of the metal chips extending below the drainage hole 101 is difficult to predict. In order to enable the rotating clamping finger cylinder 301 to clamp the metal chips, this embodiment drives the rotating clamping finger cylinder 301 to move up through the first driving cylinder 302, so as to clamp on the west side of the annular airbag 201, ensuring that the metal chips can be clamped. In addition, after the first driving cylinder 302 drives the rotating clamping finger cylinder 301 to move down, it can give the rotating clamping finger cylinder 301 enough rotation space.

[0049] Furthermore, the detachment mechanism 4 includes a second driving cylinder 401, which is laterally arranged on the base body 1. A hook 402 is arranged at the telescopic end of the second driving cylinder 401. After the first driving cylinder 302 drives the rotating finger cylinder 301 to move downward, the second driving cylinder 401 drives the hook 402 to contract, thereby detaching the metal chips wrapped around the rotating finger cylinder 301.

[0050] In this embodiment, the hook 402 can be an L-shaped structure. After the hook 402 is extended, the hook 402 can drag the entangled metal chips to make them detach from the rotating clamping finger cylinder 301. After detachment, the entangled metal chips can naturally fall under the drainage hole 101.

[0051] Furthermore, it includes a bellows 5, which is arranged below the drainage hole 101, the fingers of the rotating clamping finger cylinder 301 are inserted into the bellows 5, and the first driving cylinder 302 is arranged outside the bellows 5. When the first driving cylinder 302 drives the rotating clamping finger cylinder 301 to move up and down, it drives the bellows 5 to extend and retract.

[0052] In this embodiment, the bellows 5 can form a liquid flow path below the drainage hole 101 to prevent the cutting liquid from flowing into other locations. At the same time, the bellows 5 can surround the rotating finger clamping cylinder 301, so that when the rotating finger clamping cylinder 301 moves up and down, it can drive the bellows 5 to expand and contract without damaging the liquid flow path below the drainage hole 101.

[0053] Furthermore, a flow sensor 6 is arranged in the bellows 5 .

[0054] In this embodiment, the cutting fluid is discharged to the outside of the outer base body 1 through the bellows 5. When the drainage hole 101 is blocked, the liquid flow in the bellows 5 decreases, and the flow change is captured by the flow sensor 6. When the flow drops to a preset threshold, the control system can start the extrusion mechanism 2, the winding mechanism 3, and the detachment mechanism 4 to work in sequence.

[0055] Furthermore, the control method of the CNC machine tool base structure is:

[0056] S1, controlling the extrusion mechanism 2 to extrude metal chips;

[0057] S2, controlling the first driving cylinder 302 to drive the rotating finger cylinder 301 to move upward, and controlling the rotating finger cylinder 301 to clamp the extruded metal chips;

[0058] S3, controlling the rotating clamp finger cylinder 301 to maintain the clamping state and rotate to a certain angle;

[0059] In this step, the metal chips can be dragged downward to a certain length after being rotated at a certain angle, and the rotation angle can be set according to the shape of the clamping fingers.

[0060] S4, executing S1 and S3 several times in a loop, so that the metal chips are squeezed and wound around the rotating clamp finger cylinder 301;

[0061] In this step, by circulating S1 and S3, the metal chips are squeezed, dragged and partially wrapped by the rotating clamping finger cylinder 301, and then squeezed again by the squeezing mechanism 2, so that the metal chips are formed into slender structures in turn and wrapped around the rotating clamping finger cylinder 301 in turn.

[0062] S5, control the first driving cylinder 302 to drive the rotating finger clamping cylinder 301 to move downward to below the second driving cylinder 401, control the second driving cylinder 401 to extend the hook 402, control the first driving cylinder 302 to drive the rotating finger clamping cylinder 301 to move upward so that the metal chips are clamped by the hook, and control the second driving cylinder 401 to retract the hook 402 to remove the metal chips wrapped around the rotating finger clamping cylinder 301.

[0063] The hook 402 of this embodiment faces downward, so it is necessary to control the first drive cylinder 302 to drive the rotating finger cylinder 301 to move downward to below the second drive cylinder 401. At this time, the second drive cylinder 401 is in a retracted state to avoid the rotating finger cylinder 301 from moving downward. Then the second drive cylinder 401 extends, and the first drive cylinder 302 drives the rotating finger cylinder 301 to move upward. At this time, the hook 402 can extend into the metal chips after winding, or the hook 402 clamps the left side of the metal chips after winding. Finally, the second drive cylinder 401 shrinks, and the hook 402 hooks the metal chips wrapped around the rotating finger cylinder 301 and drags it to the right to make it detach.
