Description

Technical Field

[0001] This application relates to the field of machine tool technology, specifically to a machine tool chip removal structure and a machine tool. Background Technology

[0002] In the machine tool industry, especially in horizontal five-axis CNC machine tools, protective covers are widely used because they can effectively enclose high-speed rotating or reciprocating parts and block splashes, offering high protective reliability and system integration. However, during use, especially with wall-mounted protective covers, chips generated during machining tend to accumulate underneath, forming hard-to-clean dead corners. If the trapped chips are not removed in time, they can affect the normal operation of the machine tool and even damage equipment components.

[0003] A traditional chip removal approach involves creating a smooth, large ramp at the bottom of the protective cover. Gravity causes chips to slide from the higher end of the ramp to the lower end and into the chip conveyor. However, this ramp requires significant space, and the protective cover for horizontal five-axis machine tools and similar equipment is often compact with limited space. The ramp is severely constrained by the machine tool's layout and difficult to adapt. Furthermore, relying solely on gravity for chip removal is ineffective for sticky or fine chips, leading to residue buildup and incomplete chip removal. Another traditional approach involves creating chip removal holes in the bottom plate of the protective cover and adding an auxiliary chip removal groove below. This method weakens the protective rigidity, and chips easily clog the holes, requiring frequent manual cleaning.

[0004] To solve the above problems, a new chip removal structure needs to be developed that can adapt to the compact space of the protective cover, and can efficiently and thoroughly remove chips without affecting the structural layout and normal operation of the machine tool. Utility Model Content

[0005] The purpose of this application is to provide a machine tool chip removal structure that achieves efficient chip removal while ensuring protective performance, and solves the problems of space occupation and chip retention.

[0006] The technical solution adopted in this application is as follows:

[0007] A chip removal structure for a machine tool includes a chip removal bracket integrated into the bottom of a machine tool protective cover. The chip removal bracket has a chip removal channel formed by a bottom wall and a side wall. The bottom wall of the chip removal channel includes a first inclined surface for receiving chips and a second inclined surface for guiding chips out. The chip removal bracket has a chip removal port. The first inclined surface is located in the area directly below the protective cover. The side edge between the high end and the low end of the second inclined surface connects to the low end of the first inclined surface, so that the inclination direction of the first inclined surface and the inclination direction of the second inclined surface are arranged at an angle. The chips are guided to the second inclined surface through the first inclined surface, and the chips are guided to the chip removal port by the second inclined surface.

[0008] In this technical solution, by setting a first inclined plane and a second inclined plane, the inclined characteristics of the inclined plane are used to guide the flow of chips. The two inclined planes are arranged at an angle, so that the chips are first received by the first inclined plane and then guided to the chip discharge port by the second inclined plane. The angle design of the two inclined planes eliminates the need for the traditional large inclined plane structure, greatly reducing the space occupied and adapting to the compact layout of the protective cover. At the same time, it realizes the orderly discharge of chips, solves the problem of chip accumulation under the protective cover, and ensures that chips do not linger in the dead corners under the protective cover.

[0009] The chip removal bracket is equipped with a front flushing port, through which the water flow carries the chips on the first inclined surface to the second inclined surface.

[0010] In this technical solution, under the action of the front flushing nozzle, the water flow can actively flush the chips on the first inclined surface to the second inclined surface, avoiding the chips remaining on the first inclined surface, thus enhancing the initiative and thoroughness of chip removal, especially for chips with high viscosity or light weight, thereby improving chip removal efficiency.

[0011] The chip removal channel has a first sidewall that connects to the high end of the first inclined surface. The front flushing port is disposed on the first sidewall, and the opening direction of the front flushing port points to the connection position between the first inclined surface and the second inclined surface.

[0012] In this technical solution, the front flushing nozzle is set on the first side wall that connects with the high end of the first inclined plane, and the opening points to the connection position of the two inclined planes. This allows the water flow to act precisely on the key area where chips accumulate, flushing from the high end to the low end of the first inclined plane, maximizing the water flow impact force, ensuring that the chips are smoothly transferred from the first inclined plane to the second inclined plane, and optimizing the flushing guidance effect.

[0013] The first sidewall is provided with a plurality of front flushing ports, which are arranged at intervals along the high end of the first inclined surface.

[0014] In this technical solution, multiple front flushing nozzles are arranged at intervals along the high end of the first slope, which can cover different areas of the first slope, avoiding chip residue caused by the limited range of a single flushing nozzle, further improving the chip removal effect on the first slope, and ensuring the comprehensiveness of chip removal.

[0015] The chip removal bracket is equipped with a rear flushing port, through which the water flow carries the chips on the second inclined surface out of the chip removal port.

[0016] In this technical solution, the water jet from the rear flushing nozzle towards the second inclined surface can propel the chips on the second inclined surface to move quickly toward the chip discharge port, preventing the chips from accumulating on the second inclined surface. Especially for larger or harder chips, the impact force of the water flow can accelerate their discharge, improving the smoothness of chip discharge.

[0017] The chip removal channel has a second sidewall that connects to the high end of the second inclined surface, and the rear flushing port is disposed on the second sidewall, with the opening direction of the rear flushing port pointing towards the chip removal port.

[0018] In this technical solution, the rear flushing port is located on the second side wall that connects to the high end of the second inclined surface, and the opening points towards the chip discharge port, so that the water flow direction is consistent with the flow direction of the chips on the second inclined surface, forming a synergistic effect, enhancing the pushing effect on the chips, and ensuring that the chips are efficiently discharged to the chip discharge port.

[0019] The angle between the first inclined plane and the horizontal plane is greater than 20°; and / or, the angle between the second inclined plane and the horizontal plane is greater than 20°.

[0020] In this technical solution, by limiting the large tilt angle of the first and second inclined surfaces, the chip sliding is assisted by gravity, reducing the residence time of the chips on the inclined surfaces and lowering the risk of accumulation. Combined with the guiding effect of the inclined surfaces, the natural chip removal capability is improved.

[0021] The bottom wall of the chip removal channel also includes a buffer surface. The high end of the buffer surface is connected to the low end of the second inclined surface, and the low end of the buffer surface is connected to the chip removal port. The buffer surface includes a steep slope section and a buffer section from the high end to the low end. The slope of the steep slope section is greater than the slope of the second inclined surface, and the slope of the buffer section is less than the slope of the second inclined surface.

[0022] In this technical solution, the steep slope section of the buffer surface can quickly receive the chips and water flow from the second inclined surface and accelerate their flow. The buffer section can slow down the speed at which the chips and water flow rush towards the chip discharge port, preventing the chips and water flow from splashing due to excessive impact force. At the same time, it allows the chips and water flow to enter the chip discharge port smoothly, reducing the impact wear on the chip discharge port. The buffer surface can also optimize the smoothness of the chip discharge path.

[0023] The chip removal bracket is provided with chip removal units on both sides, and each chip removal unit includes the chip removal channel.

[0024] In this technical solution, chip removal units are provided on both sides of the chip removal bracket, which can simultaneously handle the chips generated on both sides of the machine tool. This adapts to multi-directional machining scenarios of the machine tool, improves the versatility and adaptability of the chip removal structure, and the symmetrical layout ensures that the machine tool is subjected to balanced forces, without affecting the stability of the equipment.

[0025] The machine tool provided in this application includes the chip removal structure described above.

[0026] In this technical solution, the chip removal structure is applied to machine tools, which solves the chip removal problem caused by limited space after the machine tool adopts a protective cover. This allows the machine tool to maintain the high protection of the protective cover while having efficient and compact chip removal capabilities, thereby improving the overall processing efficiency and maintenance convenience of the machine tool.

[0047] In the embodiments of this application, a chip removal structure and a machine tool are provided. For ease of explanation and understanding, the following content provided in this application is based on the illustrated product structure. Of course, those skilled in the art will understand that the above structure is only a specific example and illustrative illustration, and does not constitute a specific limitation on the technical solution provided in this application.

[0048] like Figures 1 to 5 As shown, the machine tool chip removal structure includes a chip removal bracket 2 integrated into the bottom of the machine tool protective cover 1. The chip removal bracket 2 is provided with a chip removal channel formed by the bottom wall and the side wall. The bottom wall of the chip removal channel includes a first inclined surface 21 for receiving chips and a second inclined surface 22 for guiding chips out. The chip removal bracket 2 is provided with a chip removal port 23. The first inclined surface 21 is located in the area directly below the protective cover 1. The side edge between the high end and the low end of the second inclined surface 22 connects to the low end of the first inclined surface 21, so that the inclination direction of the first inclined surface 21 and the inclination direction of the second inclined surface 22 are arranged at an angle. The chips are guided to the second inclined surface 22 through the first inclined surface 21, and the second inclined surface 22 guides the chips to the chip removal port 23.

[0049] In this application, a first inclined surface 21 and a second inclined surface 22 are provided. The first inclined surface 21 is positioned directly below the protective cover 1 to collect chips. During machine operation, chips intercepted by the protective cover 1 slide down the protective cover 1 onto the first inclined surface 21. The inclined surface guides the chip flow, and the two inclined surfaces are arranged at an angle, allowing the chips to be collected by the first inclined surface 21 and then guided to the chip discharge port 23 via the second inclined surface 22. The angled design of the two inclined surfaces creates a compact "collection-direction-discharge" path for the chips, eliminating the need for traditional large inclined surface structures and the need to occupy redundant space around the protective cover 1, significantly reducing space occupation and adapting to the compact layout of the protective cover 1. Simultaneously, it achieves orderly chip discharge, solving the problem of chip accumulation below the protective cover 1 and ensuring that chips do not remain in the dead corners below the protective cover 1. Specifically, a chip conveyor can be placed below the chip discharge port 23 to collect chips discharged from the chip discharge port 23. It should be noted that the term "connection" can refer to the side edge of the second inclined surface 22 connecting to the lower end of the first inclined surface 21. This connection can mean that the side edge of the second inclined surface 22 directly overlaps with the lower end of the first inclined surface 21, and the chip reaches the second inclined surface 22 the instant it leaves the lower end of the first inclined surface 21. Alternatively, "connection" can also mean that the side edge of the second inclined surface 22 is connected to the lower end of the first inclined surface 21 through a cross-sectional structure. In other words, the lower end of the first inclined surface 21 and the second inclined surface 22 are connected by a cross-sectional structure, and the chip falls freely onto the second inclined surface 22 after leaving the lower end of the first inclined surface 21.

[0050] As a preferred embodiment of this application, such as Figure 2 and Figure 5As shown, the chip removal bracket 2 is equipped with a front flushing inlet 24. Water flow through the front flushing inlet 24 carries the chips from the first inclined surface 21 to the second inclined surface 22. Under the action of the front flushing inlet 24, water flows out towards the first inclined surface 21, actively flushing the chips from the first inclined surface 21 to the second inclined surface 22, preventing chips from remaining on the first inclined surface 21. This enhances the initiative and thoroughness of chip removal, especially for chips that are sticky or lightweight and difficult to slide off naturally, thus improving chip removal efficiency. Specifically, the front flushing inlet 24 can be connected to the machine tool coolant system via a quick-connect pipe, supplying water to the front flushing inlet 24 through the coolant system. Alternatively, the front flushing inlet 24 can be connected to an external water source (such as a tap) via a quick-connect pipe, supplying water to the front flushing inlet 24 from an external water source.

[0051] Furthermore, such as Figure 5 As shown, the chip removal channel has a first sidewall 25 that connects to the high end of the first inclined surface 21. A front flushing port 24 is disposed on the first sidewall 25, and the opening direction of the front flushing port 24 points to the connection position between the first inclined surface 21 and the second inclined surface 22. Water is flushed from the high end to the low end of the first inclined surface 21, so that the water flow can accurately act on the key area of ​​chip accumulation, especially the key node where the chips turn from the first inclined surface 21 to the second inclined surface 22, maximizing the water flow impact force and concentrating the force to push the chips on the first inclined surface 21 to the second inclined surface 22, ensuring that the chips are smoothly transferred from the first inclined surface 21 to the second inclined surface 22, thus optimizing the flushing guidance effect.

[0052] Furthermore, the first sidewall 25 is provided with multiple front flushing nozzles 24, which are spaced apart along the high end of the first inclined surface 21. These nozzles cover different areas of the first inclined surface 21, avoiding chip residue caused by the limited range of a single nozzle, thus further improving the chip removal effect on the first inclined surface 21 and ensuring comprehensive chip removal. Especially for horizontal five-axis machine tool machining, which may generate widely distributed chips, this design ensures that chips in all areas of the first inclined surface 21 are impacted by the water flow, avoiding the dead zones that exist with a single nozzle. This is particularly beneficial for scenarios where chips scatter over a large area during the machining of large workpieces, improving the comprehensiveness of chip removal.

[0053] As a preferred embodiment of this application, such as Figure 4 and Figure 5As shown, the chip removal bracket 2 is equipped with a rear flushing port 26. The water flow through the rear flushing port 26 carries the chips on the second inclined surface 22 out of the chip removal port 23. The water flow discharged from the rear flushing port 26 towards the second inclined surface 22 provides a secondary impact on the chips on the second inclined surface 22, solving the problem of the chips slowing down due to reduced inertia or changes in angle on the second inclined surface 22. For larger chips transferred from the first inclined surface 21 to the second inclined surface 22, the water flow from the rear flushing port 26 can provide additional thrust, quickly flushing them out of the chip removal port 23, preventing chips from accumulating at the end of the second inclined surface 22, and ensuring the continuity of the chip removal process. Especially for larger or harder chips, the impact force of the water flow can accelerate their discharge, improving the smoothness of chip removal. Specifically, the rear flushing port 26 can be connected to the machine tool coolant system through a quick-connect pipe, supplying water to the rear flushing port 26 through the coolant system, or the rear flushing port 26 can be connected to an external water source through a quick-connect pipe.

[0054] Furthermore, such as Figure 5 As shown, the chip removal channel has a second sidewall 27 that connects to the high end of the second inclined surface 22. The rear flushing port 26 is set on the second sidewall 27, and the opening direction of the rear flushing port 26 points to the chip removal port 23, so that the water flow direction is consistent with the natural sliding direction of the chips on the second inclined surface 22, forming a synergistic effect of water flow propulsion combined with gravity sliding. This unidirectional force can maximize the impact effect. Even metal chips with high hardness and difficulty in sliding can be efficiently pushed to the chip removal port 23, reducing the residence time of the chips on the second inclined surface 22.

[0055] In one preferred embodiment of this application, the angle between the first inclined surface 21 and the horizontal plane is greater than 20°. In another preferred embodiment of this application, the angle between the second inclined surface 22 and the horizontal plane is greater than 20°. By limiting the angles between the first inclined surface 21 and the second inclined surface 22 and the horizontal plane to greater than 20°, both have a large tilt angle, which enhances the natural sliding tendency of the chips by utilizing gravity. For non-adhesive chips (such as cast iron chips) generated during processing, the larger tilt angle allows them to flow quickly along the inclined surface, reducing the contact time with the inclined surface and lowering the risk of adhesion; at the same time, combined with the water flow impact from the flushing nozzle, the two forces are superimposed, further increasing the movement speed of the chips on the inclined surface and avoiding jamming of the chips during the sliding process due to an excessively small angle.

[0056] As a preferred embodiment of this application, such as Figure 2 and Figure 3As shown, the bottom wall of the chip removal channel also includes a buffer surface 28. The high end of the buffer surface 28 connects to the low end of the second inclined surface 22, and the low end of the buffer surface 28 connects to the chip removal port 23. The buffer surface 28 includes a steep slope section 281 and a buffer section 282 from the high end to the low end. The slope of the steep slope section 281 is greater than the slope of the second inclined surface 22, and the slope of the buffer section 282 is less than the slope of the second inclined surface 22. The steep slope section 281 of the buffer surface 28 can quickly receive the chips and water flow from the second inclined surface 22 and accelerate their flow, preventing chips from accumulating in the transition area between the second inclined surface 22 and the chip removal port 23. The buffer section 282 can slow down the speed at which chips and water flow rush towards the chip removal port 23, preventing chips and water flow from splashing or rebounding due to excessive impact force. At the same time, it allows chips and water flow to be smoothly discharged from the chip removal port 23 and enter the chip conveyor, reducing impact wear on the chip removal port 23 and also reducing impact damage to the chip conveyor. The buffer surface 28 can also optimize the smoothness of the chip removal path.

[0057] As a preferred embodiment of this application, such as Figure 2 , Figure 3 and Figure 5 As shown, chip removal units are provided on both sides of the chip removal bracket 2. Each chip removal unit includes a chip removal channel, which can simultaneously handle chips generated on both sides of the machine tool. This adapts to multi-directional machining scenarios of the machine tool. Chips generated on the left and right sides of the machine tool can be discharged through the corresponding first inclined surface 21, second inclined surface 22, and flushing port, respectively. There is no need to design an additional chip removal channel on one side, which simplifies the overall structure and improves the versatility and adaptability of the chip removal structure. In the preferred embodiment, the openings of the chip removal channels of the chip removal units on both sides can be arranged facing each other, so that the overall force of the machine tool is balanced and does not affect the stability of the equipment. At the same time, it makes the force when the chips are discharged more balanced, and the bracket or protective cover 1 will not be subjected to unbalanced load due to chip removal on one side, which improves the stability of the structure. Moreover, it can also make the chip removal ports 23 of the chip removal channels on both sides closer together, so that they can share the same chip removal machine 5 for chip removal.

[0058] The machine tool provided in this application includes the chip removal structure described above. Specifically, in Figure 6 , Figure 7 and Figure 8 The illustrated embodiment shows a machine tool that also includes a base 3. Figure 7The Z-axis of the machine tool is indicated by a double-headed arrow Z, and the X-axis by a double-headed arrow X. The base 3 has internal chip guide plates 4 on both sides, and a chip conveyor 5. A protective cover 1 is installed on the base 3 and protects one end of the internal chip guide plates 4. A chip conveyor bracket 2 is located at the bottom of the protective cover 1. During machining, some chips are discharged into the chip conveyor 5 through the internal chip guide plates 4 on both sides; another portion of chips, blocked by the protective cover 1, falls onto the first inclined surface 21 of the chip conveyor bracket 2 at the bottom of the protective cover 1. Then, the chips are flushed into the second inclined surface 22 by the front flush nozzle 24, and the rear flush nozzle 26 flushes the chips on the second inclined surface 22 to the chip discharge port 23, thus discharging the chips into the chip conveyor 5. Overall, the chip flow direction of the first inclined plane 21 is from front to back and downward along the Z-axis of the machine tool (from front to back means the direction of the lower arrow in the double arrow Z pointing to the upper arrow), and the chip flow direction of the second inclined plane 22 is from both sides to the middle and downward along the X-axis of the machine tool.

[0059] Therefore, applying this chip removal structure to machine tools solves the chip removal problem caused by limited space after the adoption of protective cover 1 in machine tools such as horizontal five-axis machine tools. On the one hand, its compact structure does not affect the complex axis layout and protection system of the machine tool; on the other hand, the efficient chip removal capability ensures that chips do not accumulate in the working area during the machining process, reducing workpiece surface scratches or equipment failures caused by chip residue, improving the machining accuracy and continuous operation capability of the machine tool, and enabling the machine tool to have efficient and compact chip removal capability while maintaining the high protection of protective cover 1, thereby improving the overall machining efficiency and maintenance convenience of the machine tool.
