Description

Technical Field

[0001] This application relates to the field of machining, and more specifically, to a chip removal device for machine tools. Background Technology

[0002] Machine tools are used to machine workpieces. During machining, the main process involves using cutting tools to remove material from the workpiece. Coolant is poured onto the cutting tools and workpiece to cool them down. The coolant and machining debris accumulate in the machine tool and need to be removed using a chip removal device.

[0003] Currently, chip removal mainly relies on the rotation of a spiral plate in the chip removal groove of a machine tool to actively output waste chips. However, in some cases, a large amount of coolant is poured onto the workpiece and the cutting tool. The spiral plate, placed in the chip removal groove, will block most of the groove, affecting the speed at which the coolant is discharged. This can easily cause coolant to overflow from the chip removal groove, carrying waste chips with it, thus affecting the efficiency of chip removal. Utility Model Content

[0006] Furthermore, a connecting rod is provided at the end of the spiral strip, and the connecting rod coincides with the axis of the spiral strip; the connecting rod is connected to the output end of the drive component.

[0007] Furthermore, the spiral strip has a spiral surface, on which a plurality of protrusions are provided, the protrusions being inclined relative to the spiral surface; the plurality of protrusions are evenly distributed along the extension trajectory of the spiral strip.

[0008] Furthermore, a fixing rod is provided in the chip removal cavity, and the fixing rod has an air injection chamber and an air injection hole. The air injection chamber is connected to the chip removal cavity through the air injection hole. The driving component is also used to inject air into the air injection chamber.

[0009] Furthermore, there is an annular drainage chamber between the fixed rod and the spiral strip.

[0010] Furthermore, the driving component includes a drive motor and a transmission mechanism, wherein the drive motor is connected to the connecting rod via the transmission mechanism; the transmission mechanism causes the axis of the drive motor to be different from the axis of the connecting rod.

[0015] The beneficial effects of this application are as follows:

[0016] The chip removal cavity in the middle of the spiral strip allows for better flow of coolant.

[0032] A chip removal device for a machine tool, the machine tool having a chip removal groove 1, with the chip removal device disposed within the chip removal groove 1. During machine tool operation, coolant is poured onto the workpiece during machining. The coolant flows into the chip removal groove 1, and the waste chips generated during machining also enter the chip removal groove 1. The purpose of the chip removal groove 1 is to discharge the waste chips outwards. The chip removal device includes: a driving component and a spiral strip 2 connected to the output end of the driving component; the spiral strip 2 has a chip removal cavity in its middle, and the edge of the spiral strip 2 is close to the inner wall of the chip removal groove 1. The chip removal cavity in the middle of the spiral strip 2 allows for better flow of coolant. Therefore, even with a very large amount of coolant injected, coolant will not overflow upwards from the chip removal groove 1. That is, compared to the spiral plate in conventional technology, the spiral strip 2 is essentially non-existent, completely not affecting the normal discharge of coolant, whereas the spiral plate in conventional technology would slow down the discharge rate of coolant. Therefore, the better outward discharge of coolant in this application can prevent waste chips carrying coolant from adhering to the machine tool wall above the chip discharge tank 1, avoid the situation where some waste chips are difficult to discharge, and better discharge waste chips.

[0033] Specifically, a connecting rod 3 is provided at the end of the spiral strip 2, and the connecting rod 3 coincides with the axis of the spiral strip 2; the connecting rod is connected to the output end of the driving component. The setting of the connecting rod 3 can better connect the spiral strip 2 to the driving component, which can be a drive motor 5. Since the connection between the spiral strip 2 and the drive motor 5 is costly, the connection between the connecting rod 3 and the output end of the drive motor 5 can be achieved through various couplings, which is more cost-effective.

[0034] Specifically, the spiral strip 2 has a spiral surface with multiple protrusions on it, the protrusions being inclined relative to the spiral surface; the multiple protrusions are evenly distributed along the extension trajectory of the spiral strip 2. The protrusions on the spiral surface can agitate the coolant in the chip removal groove 1, increasing the kinetic energy of the coolant, so that when the coolant is discharged, it can better impact and discharge the waste chips outward.

[0035] Specifically, a fixing rod 4 is installed in the chip removal cavity. The fixing rod 4 has an air injection chamber 41 and an air injection hole. The air injection chamber 41 is connected to the chip removal cavity through the air injection hole. The driving component is also used to inject air into the air injection chamber 41. By injecting air into the coolant of the chip removal groove 1 through the air injection chamber 41 and the air injection hole, the waste chips in the coolant can be better discharged, avoiding the waste chips from getting stuck. Alternatively, when the waste chips are long, the air can be used to better blow them apart or better discharge longer waste chips, and also prevent longer waste chips from getting tangled on the spiral strip 2. The longer waste chips are generated during the machining process.

[0036] Specifically, there is an annular drainage chamber between the fixing rod 4 and the spiral strip 2. The space between the fixing rod 4 and the spiral strip 2 ensures better efficiency in coolant drainage.

[0037] Specifically, the driving component includes a drive motor 5 and a transmission mechanism 6. The drive motor 5 is connected to the connecting rod 3 via the transmission mechanism 6. The transmission mechanism 6 makes the axis of the drive motor 5 different from the axis of the connecting rod 3. The transmission mechanism 6 adopts one of gear transmission, belt pulley transmission, and sprocket transmission. The driving component also includes an air pump 7, which is connected to the fixed rod 4. Both the drive motor 5 and the air pump 7 are mounted on the machine tool. The transmission mechanism 6 allows the air pump 7 to inject air into the air injection chamber 41.

[0038] Specifically, a bracket 8 is provided in the chip removal groove 1, and the connecting rod 3 is rotatably connected to the bracket 8.

[0039] In other embodiments, the fixing rod 4 is fixed to the connecting rod 3, and the air injection chamber 41 is formed on the fixing rod 4 and the connecting rod 3. The driving member injects air from the air injection chamber 41 of the connecting rod 3. That is, the fixing rod 4 is formed by extending the connecting rod 3. In this case, the air pump 7 is connected to the end face of the connecting rod 3 through a rotary joint, while the drive motor 5 and the transmission mechanism 6 are connected to the outer wall of the connecting rod 3 away from the end face.

Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
