Description

Technical Field

[0001] The utility model belongs to the technical field of turret milling machines, and particularly relates to a turret milling machine with a chip cleaning assembly. Background Technique

[0002] A turret milling machine is a machine tool that drives a workpiece to move by a workbench and rotates a tool by a high-speed spindle for cutting, and its shape is similar to a turret. It has X, Y, and Z-direction guide pairs, and in particular, a workbench is installed on the Y-axis. The workpiece is fixed on the workbench by a fixture, and the tool is driven by the high-speed spindle to cut. The cut iron chips fall on the workbench, and generally, an air gun is used for blowing.

[0003] In order to save manpower, a negative pressure pipe is added to the turret milling machine to suck iron chips. A vacuum pump is arranged below the turret milling machine to suck the air in the negative pressure pipe to form a negative pressure condition to attract iron chips.

[0004] When cleaning the iron chips on the workbench, a number of negative pressure pipes are respectively fixed on both sides of the workbench, and the negative pressure pipes are used to attract the iron chips. However, the attraction effect is mainly concentrated at the ports of the negative pressure pipes, and it is difficult to cover the workbench. Increasing the number of negative pressure pipes requires a vacuum pump with a greater power, and too many negative pressure pipes are crowded and may block the sight of the staff. Therefore, we propose a turret milling machine with a chip cleaning assembly. Content of the Utility Model

[0005] The purpose of the utility model is to provide a turret milling machine with a chip cleaning assembly, which only needs two nozzles to blow the iron chips, without manual cleaning of the iron chips, and can reduce the shielding effect caused by the sight of the staff.

[0006] The technical solution adopted by the utility model is specifically as follows:

[0007] A turret milling machine with a chip cleaning component, comprising a machine base. Above the machine base is provided a workbench. At both lower edges of the workbench are fixed slag receiving grooves. On the side of each of the two slag receiving grooves away from the workbench, it is turned up, and a sliding mechanism is provided at the folding part. Above each of the two slag receiving grooves is provided a slide bar connected to the sliding mechanism. At the upper edges of the two sides of the workbench are respectively horizontally provided two nozzles. The air outlets of the two nozzles are both directed towards the middle of the workbench. At the tails of the two nozzles are both connected and fixed with air pipes. The two air pipes respectively cross over the adjacent slag receiving grooves upwards and are fixedly connected to the upper surfaces of the adjacent slide bars. When the iron chips need to be cleaned, the air source is turned on, and air flow is pumped towards the nozzles along the air pipes, so that the two nozzles respectively blow air horizontally towards the upper surface of the workbench along the X-axis. Then, the sliding mechanism is started to move the two nozzles along the Y-axis, so that the air flow ejected by the nozzles traverses horizontally along the workbench. Only two nozzles are needed to blow the iron chips on the upper surface of the workbench, blow the iron chips into the two slag receiving grooves, and collect the iron chips. There is no need to manually clean the iron chips generated by the processed workpieces, which can reduce the shielding effect caused by the line of sight of the staff and facilitate the staff's line of sight to fall on the surface of the workpiece on the workbench.

[0008] At the ports of the two air pipes away from the nozzles are both connected and fixed with bellows. When the two air pipes traverse, the bellows are stretched, and the bellows are stably connected to the air source to keep the air path unblocked, avoiding accidental interruption of the air flow in the air pipes.

[0009] At the lower ends of the two bellows are both connected and installed with booster pumps. The two booster pumps are both installed at the lower edge of the machine base. When blowing the iron chips, the booster pumps can be started to compress the air flow and then pump it to the two nozzles along the bellows. The effect of this compression is relatively weak, so that the compressed air flow ejected by the nozzles will not cause the iron chips to fly around.

[0010] Each of the sliding mechanisms includes an electric slide rail fixedly connected to the folding part of the slag receiving groove. On the outside of the two electric slide rails are slidably installed flange sliders. The upper surfaces of the two flange sliders are both fixedly connected to the lower ends of the adjacent slide bars. The two electric slide rails can independently move the flange sliders along the Y-axis, driving the two nozzles to eject compressed air flow in a staggered manner, avoiding the mutual cancellation of the two compressed air flows.

[0011] In the middle of the lower walls of the two slag receiving grooves are both triangular protrusions, forming two inclined surfaces. After the iron chips fall into the slag receiving grooves, they respectively slide down along the inclined surfaces, and the iron chips can be guided to both ends of the slag receiving grooves for aggregation.

[0012] At the lower surfaces of the two slag receiving grooves are both connected and fixed with slag leakage pipes. The ports of the slag leakage pipes are both directly opposite to the lower edges of the triangular protrusions of the slag receiving grooves. After the iron chips reach both ends of the slag receiving grooves, they fall into the slag leakage pipes. The lower ends of the slag leakage pipes can be inserted into the snake skin bags for receiving the iron chips and automatically collecting the iron chips.

[0013] The technical effects achieved by the present utility model are:

[0014] A turret milling machine with a chip cleaning component according to the present utility model. When it is necessary to clean the iron chips, the air source is turned on, and air is pumped along the air pipe towards the nozzles, so that the two nozzles blow air horizontally towards the upper surface of the workbench along the X-axis respectively. Then, the sliding mechanism is started to move the two nozzles along the Y-axis, so that the air flow ejected by the nozzles traverses the workbench. Only two nozzles are needed to blow the iron chips on the upper surface of the workbench into the two slag receiving grooves to collect the iron chips, eliminating the need for manual cleaning of the iron chips generated by the processed workpieces, reducing the shielding effect caused by the line of sight of the staff, and facilitating the staff's line of sight to fall on the surface of the workpiece on the workbench.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the specific scope of protection claimed by the present utility model.

[0023] As Figures 1-5As shown in the figure, a turret milling machine with a chip cleaning component includes a machine base 1, and the machine base 1 can select a turret milling machine of the FTM-4S5AG model. An X-axis slide rail assembly 12, a Y-axis slide rail assembly 13, and a Z-axis slide rail assembly 14 are sequentially installed on the upper end of the machine base 1 from bottom to top. A workbench 2 is arranged above the machine base 1, and the workbench 2 is fixed on the upper surface of the Y-axis slide rail assembly 13. The operator can turn the handwheel to move the workbench 2 along the X-axis slide rail assembly 12 and the Y-axis slide rail assembly 13 respectively. A tool shaft is vertically installed on the Z-axis slide rail assembly 14 for rotating the cutting tool. Especially after the workpiece is fixed on the workbench 2 with a fixture, the motor can be started to rotate the tool shaft and the cutting tool to machine the workpiece, and the iron chips generated by the machining fall on the upper surface of the workbench 2.

[0024] Scrap collection troughs 3 are fixed to both lower edges of the workbench 2. One side of each of the two scrap collection troughs 3 away from the workbench 2 is turned up, and a sliding mechanism is arranged at the turned-up part. Slide rods 4 connected to the sliding mechanisms are arranged above the two scrap collection troughs 3. Two spray nozzles 5 are horizontally arranged on the two upper edges of the workbench 2 respectively. The air outlets of the two spray nozzles 5 face the middle of the workbench 2. Air pipes 6 are fixedly connected to the tails of the two spray nozzles 5. The two air pipes 6 are both connected to the air source. The two air pipes 6 respectively cross over the adjacent scrap collection troughs 3 upwards and are fixedly connected to the upper surfaces of the adjacent slide rods 4. When machining the workpiece, the air source is closed. When it is necessary to clean the iron chips, the air source is turned on, and air flow is pumped along the air pipes 6 towards the spray nozzles 5, so that the two spray nozzles 5 blow air horizontally along the X-axis towards the upper surface of the workbench 2 respectively. Then, the sliding mechanism is started to move the two slide rods 4, the two spray nozzles 5, and the two air pipes 6 along the positive or negative Y-axis, so that the air flow sprayed by the spray nozzles 5 traverses the workbench 2. Only two spray nozzles 5 are needed to blow the iron chips on the upper surface of the workbench 2 into the two scrap collection troughs 3 to collect the iron chips. There is no need to manually clean the iron chips generated by machining the workpiece, which can reduce the shielding effect caused by the operator's line of sight and facilitate the operator's line of sight to fall on the workpiece surface on the workbench 2.

[0025] Among them, the slide rods 4, the spray nozzles 5, and the air pipes 6 are used as the chip cleaning component, which integrates chip blowing and chip collection. The height of the turned-up part of the scrap collection trough 3 above the workbench 2 does not exceed 2 cm, and there is a certain horizontal distance from the workbench 2, and this distance can accommodate a certain amount of iron chips. The air pipes 6 can be made of alloy material, which can stably support the spray nozzles 5 and relieve the reaction force brought by the air flow.

[0026] As Figure 1 、 Figure 2 and Figure 3 shown in the figure, bellows 7 are fixedly connected to the ports of the two air pipes 6 away from the spray nozzles 5. When the two air pipes 6 traverse, the bellows 7 are stretched, and the bellows 7 are stably connected to the air source to keep the air path unblocked, avoiding accidental interruption of the air flow in the air pipes 6.

[0027] As Figure 1 andFigure 3 As shown, pressure pumps 8 are connected and installed at the lower ends of both bellows 7. Both pressure pumps 8 are signal-connected to the control panel of the turret milling machine. The pressure pump 8 can be a TGV series micro air pump with a working voltage of 12 / 24VCD. Both pressure pumps 8 are installed at the lower edge of the machine base 1. When purging iron filings, the pressure pump 8 can be started to compress the air flow and then pump it along the bellows 7 to the two nozzles 5. The effect of this compression is weak, so that the compressed air flow ejected from the nozzles 5 will not cause the iron filings to fly around.

[0028] As Figure 3 、 Figure 4 and Figure 5 shown, the sliding mechanisms both include electric slide rails 9 fixedly connected to the folding points of the slag receiving trough 3. The electric slide rails 9 can be double-axis core synchronous belt modules of the HFB40 model with an accuracy of ±0.05mm. Both electric slide rails 9 are signal-connected to the control panel of the turret milling machine. Flange sliders 10 are slidably installed outside both electric slide rails 9. The upper surfaces of both flange sliders 10 are fixedly connected to the lower ends of the adjacent sliding rods 4. Both electric slide rails 9 can independently move the flange sliders 10 along the Y-axis, driving the two nozzles 5 to eject compressed air flow in a staggered manner, avoiding the cancellation of the two compressed air flows.

[0029] As Figure 2 、 Figure 3 and Figure 4 shown, the middle parts of the lower walls of both slag receiving troughs 3 are triangular protrusions, forming two inclined surfaces. After the iron filings fall into the slag receiving trough 3, they slide down along the inclined surfaces respectively, and the iron filings can be guided to both ends of the slag receiving trough 3 for aggregation.

[0030] As Figure 2 、 Figure 3 and Figure 4 shown, leakage pipes 11 are fixedly connected and communicated with the lower surfaces of both slag receiving troughs 3. The ports of the leakage pipes 11 are exactly opposite to the lower edges of the triangular protrusions of the slag receiving trough 3. After the iron filings reach both ends of the slag receiving trough 3, they fall into the leakage pipes 11. The lower ends of the leakage pipes 11 can be inserted into the snake skin bags for receiving the iron filings and automatically collecting the iron filings.

[0031] The working principle of the present utility model is as follows: When it is necessary to clean the iron filings, the air source is turned on, and the air flow is pumped towards the nozzles 5 along the air delivery pipe 6, so that the two nozzles 5 blow air horizontally towards the upper surface of the workbench 2 along the X-axis respectively. Then the sliding mechanism is started to move the two nozzles 5 along the Y-axis, so that the air flow ejected from the nozzles 5 traverses along the workbench 2. Only two nozzles 5 are needed to purge the iron filings on the upper surface of the workbench 2, blow the iron filings into the two slag receiving troughs 3, and collect the iron filings. There is no need to manually clean the iron filings generated by the processed workpieces, which can reduce the shielding effect caused by the staff's line of sight and facilitate the staff's line of sight to fall on the workpiece surface on the workbench 2.

[0032] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model, unless otherwise specified and limited, are implemented according to the conventional means in the art.
