Description

Technical Field

[0001] The utility model relates to the technical field of machine tool cleaning, in particular to an iron chip stripping device for a CNC machining center machine tool. Background Art

[0002] Machine tools are generally divided into metal cutting machine tools, forging machine tools and woodworking machine tools. However, parts with high precision requirements and fine surface roughness requirements generally need to be finally processed on machine tools using cutting methods. When processing the workpiece, the machine tool will produce a large amount of iron chips and emulsion, and the iron chips need to be cleaned during processing.

[0003] When the tool is cutting a part, the strips of iron chips generated will be wrapped around the tool, affecting the processing efficiency and quality, and may even cause damage to the tool or scratches on the workpiece surface. The existing method of blowing the iron chips by water or air flow usually blows in the direction of the cutting point. The strips of iron chips wrapped around the outside of the tool are not easy to be blown off by the air or water flow, and the cleaning effect is poor. Utility Model Content

[0004] The purpose of the utility model is to provide a chip stripping device for a CNC machining center machine tool to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A chip stripping device for a CNC machining center machine tool comprises a machine tool and a tool holder arranged inside the machine tool.

[0007] An installation component is installed on one side of the tool holder at the tool;

[0008] A cleaning assembly is installed inside the mounting assembly, the cleaning assembly comprising a rotating block, a cross edge being fixedly mounted on one end surface of the rotating block, an air passage being provided inside both the rotating block and the cross edge, and one end of the air passage passing through the surface of one end of the cross edge;

[0009] The cutting assembly is fixedly installed at the lower end of the mounting assembly.

[0010] Further, the slitting assembly includes:

[0011] The electric push rod is fixedly installed on the lower surface of the U-shaped frame;

[0012] The slitting ring is movably sleeved on the outside of the cross edge, and its lower end is fixedly connected to the output end of the electric push rod;

[0013] A plurality of guide plates are fixedly mounted on the inner surface of the slitting ring at equal angles.

[0014] Furthermore, a plurality of air distribution holes are provided at equal angles on the outer surface of the cross edge, and the air distribution holes are connected to the air passage, and a connection port fixedly installed on the outer surface of the rotating block and fixedly connected to the air passage.

[0015] Furthermore, a plurality of electromagnets are fixedly embedded and installed at equal angles inside the cross edge, and a nozzle is fixedly embedded and installed at one end of the airway.

[0016] Further, the installation component includes:

[0017] U-shaped frame, movably mounted on the outside of the tool holder;

[0018] A connecting seat, fixedly mounted on one side surface of the U-shaped frame;

[0019] The motor is fixedly installed on the upper end of one surface of the U-shaped frame.

[0020] Preferably, a bolt is screwed onto the upper surface of the U-shaped frame, and the bolt passes through the U-shaped frame, and a rocker is fixedly mounted on the output end of the motor.

[0021] Preferably: the rotating block is rotatably connected to the inside of the connecting seat, and both ends pass through the connecting seat, the upper end of the rotating block passes through the connecting seat and is fixedly installed with a shift rod, the lower end of the rotating block passes through the connecting seat and is fixedly installed with a coil spring, and one end of the coil spring is fixedly connected to the connecting seat.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. By connecting the connection port to a device that can provide high-pressure airflow or water flow, the airflow and water flow can enter the airway and then be discharged from the nozzle and multiple air holes to cool the cutting area. At the same time, the electromagnet works to increase the attraction of the cross edge to the strip iron chips, making it easier for the strip iron chips to wrap around the outside of the cross edge.

[0024] 2. By tightening the bolts to press against the tool holder, the U-shaped frame is fixed to the outside of the tool holder, which also facilitates the movement of the cross edge. The motor is running, and the lever drives the rotating block to rotate, so that the cross edge rotates. When the lever is separated from the rocker arm, the elastic force of the coil spring resets the rotating block to rotate back, so that the cross edge swings back and forth, and the strip iron chips produced by the tool cutting are wrapped around its outside, or pushed to one side to reduce the strip iron chips wrapped around the outside of the tool.

[0025] 3. When strip iron chips are wrapped around the outside of the cross edge, the electric push rod extends to move the slitting ring along the outside of the cross edge, squeezing the strip iron chips outside the cross edge and cutting the strip iron chips at the sharp edge position of the four edges of the cross edge. At this time, the electromagnet stops working, and the air or water flow blown out of the air hole hits the guide plate, so that the air and water flow hit the outer surface of the cross edge, washing away the iron chips on its surface, so as to avoid the fluffy accumulation of long strip iron chips, making them more smooth to discharge, improving the cleaning effect, ensuring the processing efficiency and quality of the machine tool, and avoiding damage to the tool or scratches on the workpiece surface.

[0033] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See also Figure 1-6In an embodiment of the present invention, a chip stripping device for a CNC machining center machine tool includes a machine tool 1 and a tool holder 101 arranged inside the machine tool 1, a mounting assembly 2, which is mounted on one side of the tool holder 101 at the tool position, a cleaning assembly 3, which is mounted on the inner side of the mounting assembly 2, and the cleaning assembly 3 includes a rotating block 301, a cross edge 302 is fixedly mounted on the surface of one end of the rotating block 301, and air ducts 303 are opened inside the rotating block 301 and the cross edge 302, and one end of the air duct 303 passes through the surface of one end of the cross edge 302, and a cutting assembly 4 is fixedly mounted on the lower end of the mounting assembly 2.

[0035] Specifically, the mounting assembly 2 is used to fix the cleaning assembly 3 so that it is fixed on one side of the tool. The cleaning assembly 3 swings the strip iron chips generated by cutting so that they are not entangled and accumulated on the outside of the tool. At the same time, under the action of the cutting assembly 4, the strip iron chips are cut so that they fall into the chip groove of the machine tool 1 in small segments.

[0036] Example 1

[0037] like Figure 5 and Figure 6 As shown, in this embodiment, a plurality of air distribution holes 306 are opened at equal angles on the outer surface of the cross edge 302, and the air distribution holes 306 are connected to the air duct 303, and a connecting port 304 fixedly installed on the outer surface of the rotating block 301 and fixedly connected to the air duct 303; a plurality of electromagnets 307 are fixedly embedded and installed at equal angles inside the cross edge 302, and a nozzle 305 is fixedly embedded and installed at one end of the air duct 303.

[0038] In this embodiment, the connection port 304 is connected to a device that can provide high-pressure airflow or waterflow, so that the airflow and waterflow can enter the airway 303, and then be discharged from the nozzle 305 and multiple air distribution holes 306 to cool the cutting area. At the same time, the electromagnet 307 works to increase the attraction of the cross edge 302 to the strip iron chips, making it easier for the strip iron chips to wrap around the outside of the cross edge 302.

[0039] like Figure 2-5 As shown, in this embodiment, the mounting assembly 2 includes: a U-shaped frame 201 that is movably sleeved on the outside of the tool holder 101, a connecting seat 202 that is fixedly mounted on one side surface of the U-shaped frame 201, and a motor 204 that is fixedly mounted on the upper end of one side surface of the U-shaped frame 201; a bolt 203 is screwed into the upper end surface of the U-shaped frame 201, and the bolt 203 passes through the U-shaped frame 201, and a rocker arm 205 is fixedly mounted on the output end of the motor 204; a rotating block 301 is rotatably connected to the inside of the connecting seat 202, and both ends pass through the connecting seat 202, a shift rod 308 is fixedly mounted on the upper end of the rotating block 301 that passes through the connecting seat 202, and a coil spring 309 is fixedly mounted on the lower end of the rotating block 301 that passes through the connecting seat 202, and one end of the coil spring 309 is fixedly connected to the connecting seat 202.

[0040] During specific implementation, by tightening the bolt 203, it is pressed against the tool holder 101, and the U-shaped frame 201 is fixed to the outside of the tool holder 101, which also facilitates the movement of the cross edge 302. The motor 204 is running, driving the rocker arm 205 to rotate, causing the rocker arm 205 to swing the lever 308, so that the lever 308 drives the rotating block 301 to rotate, so that the cross edge 302 rotates. When the lever 308 is separated from the rocker arm 205, the elastic force of the coil spring 309 is reset, so that the rotating block 301 rotates back, so that the cross edge 302 swings back and forth, and the strip iron chips generated by the tool cutting are wrapped around its outside, or pushed to one side, thereby reducing the strip iron chips wrapped around the outside of the tool.

[0041] like Figure 3-6 As shown, in this embodiment, the slitting assembly 4 includes: an electric push rod 403 fixedly installed on the lower end surface of the U-shaped frame 201, a slitting ring 401 movably sleeved on the outside of the cross edge 302, and its lower end is fixedly connected to the output end of the electric push rod 403, and a plurality of guide plates 402 are fixedly installed at equal angles on the inner surface of the slitting ring 401.

[0042] During specific implementation, when strip iron filings are wrapped around the outside of the cross edge 302, the electric push rod 403 extends, causing the slitting ring 401 to move along the outside of the cross edge 302, squeezing the strip iron filings on the outside of the cross edge 302, and slitting the strip iron filings at the sharp edge position of the four edges of the cross edge 302. At this time, the electromagnet 307 stops working, and the air flow or water flow blown out of the air hole 306 hits the guide plate 402, so that the air flow and water flow hit the outer surface of the cross edge 302, washing away the iron filings on its surface, so as to avoid the fluffy accumulation of long strip iron filings, making them more smoothly discharged, improving the cleaning effect, ensuring the processing efficiency and quality of the machine tool 1, and avoiding damage to the tool or scratches on the workpiece surface.

[0043] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
