Description

Technical Field

[0001] This invention relates to the field of CNC machine tools, specifically to the field of chip removal in CNC machine tools, and particularly to a CNC machining center with a multi-directional chip removal structure. Background Technology

[0002] A CNC machining center is a CNC machine tool equipped with a tool magazine and capable of automatic tool changing, performing various machining operations on workpieces. During operation, CNC machine tools generate waste chips. In existing technology, these chips are generally removed by a chip conveyor. Chip conveyors are categorized into chain-type, scraper-type, spiral-type, and permanent magnet-type chip conveyors, among others. Each of these types has its own shortcomings. For example, chain-type and scraper-type chip conveyors push the chips away using chains or scrapers. However, the chips generated during CNC machining of metal workpieces are generally spiral-shaped, with thin and curled edges, possessing strong hooking capabilities. Therefore, pushing the chips away using chains or scrapers generates significant noise and easily causes wear on the walls of the conveying pipes. Furthermore, when the chips are blown into the conveying pipe, the chips... The direction of chip removal is unpredictable, and it's easy for the chip to extend roughly parallel to the length of the conveying pipe, i.e., roughly perpendicular to the chain plate or scraper. In this case, there is point contact between the chip and the chain plate or scraper. Coupled with the hooking force between the chip and the pipe wall, it is difficult for the chain plate or scraper to push away the chip, which needs improvement. Spiral chip conveyors generally use an auger to pull the chip away. The auger cannot make contact with the pipe wall, so there is a gap between the auger's spiral blades and the pipe wall. The ends of metal chips can easily enter the gap, which can cause interference with the auger's rotation and generate noise, or even jam the auger. Permanent magnetic chip conveyors can only pull away magnetic metal chips; non-magnetic metal or plastic chips cannot be pulled away.

[0003] In addition, CNC machine tools use cutting fluid, and the chip removal technology mentioned above cannot separate waste chips from waste cutting fluid.

[0004] Based on the above, the present invention proposes a CNC machining center with a multi-directional chip removal structure. Summary of the Invention

[0005] To address the problems mentioned in the background above, the present invention provides a CNC machining center with a multi-directional chip removal structure.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows.

[0007] A CNC machining center with a multi-directional chip removal structure includes a bed and a worktable. An outer guide table is installed on the bed and surrounds the worktable. The worktable is rectangular in shape, and the outer guide table is annular in shape with a rectangular horizontal cross-section. The distance between the two inner walls of the outer guide table along the width direction and the distance between the two inner walls along the length direction are both vertical and increase from bottom to top.

[0008] The outer surface of the worktable is provided with an inner guide platform. The distance between the two sides of the inner guide platform along the width direction is vertical and decreases from bottom to top. The two sides of the inner guide platform along the length direction are each composed of two inclined surfaces. The distance between the two inclined surfaces decreases vertically from bottom to top and the distance direction is parallel to the width direction of the worktable.

[0009] The two sides of the inner guide platform along the length direction are respectively connected to the two inner walls of the outer guide platform along the length direction. The bottom of the area between the inner guide platform and the outer guide platform is open and consists of two openings, each of which is equipped with a chip removal component.

[0010] Furthermore, the chip removal component includes a chip removal channel, the upper end of which is open and connected to an opening, the bottom of which is arc-shaped and curved upwards, a chip removal assembly is provided inside the chip removal channel, and a drive assembly is provided below the chip removal channel. The drive assembly is used to drive the chip removal assembly to reciprocate within the chip removal channel. When the chip removal assembly moves, it can separate the waste chips and cutting fluid within the chip removal channel and push the waste chips out.

[0011] Furthermore, each end of the chip removal channel is provided with an output channel that is tilted downwards.

[0012] Furthermore, the chip removal assembly includes a chip removal bracket, and a strong magnet is provided at the bottom of the chip removal bracket;

[0013] The drive assembly includes a drive bracket and a synchronous belt mounted on the drive bracket with the conveying direction parallel to the length direction of the chip removal channel. A slide block is slidably mounted on the drive bracket along the length direction of the chip removal channel. The slide block is connected to the synchronous belt. A lower strong magnet is provided on the upper surface of the slide block. The upper strong magnet is located above the lower strong magnet, and the magnetic force between the two is a magnetic attraction force.

[0014] Furthermore, the chip removal bracket includes two inclined plates. The distance between the two inclined plates is parallel to the length direction of the chip removal channel. The distance between the two inclined plates is vertical and decreases from bottom to top. Each of the two inclined plates has a side plate on both sides along the width direction of the chip removal channel. The two side plates are respectively attached to the two sides of the chip removal channel along the width direction. A base is provided between the bottoms of the two side plates, and an upper strong magnet is placed on the base.

[0015] Furthermore, a rotating roller is rotatably mounted on the bottom of the base. The axis of the rotating roller is parallel to the width direction of the chip removal channel. The rotating roller is supported by the bottom of the chip removal channel. At least two rotating rollers are arranged along the length direction of the chip removal channel.

[0016] Furthermore, each inclined plate is provided with a chip removal plate, and each of the two inclined plates has a protrusion on its opposite side. The chip removal plates are arranged at an inclination and the inclination direction of the chip removal plates is parallel to the inclination direction of the corresponding inclined plates. The upper inclined surface of the chip removal plate is in contact with the lower inclined surface of the inclined plate. A guide rod extends vertically from the upper end of the chip removal plate. The guide rod is slidably connected to the protrusion. A spring is sleeved on the outside of the guide rod between the protrusion and the chip removal plate. Initially, under the action of the spring force, the bottom of the chip removal plate contacts the bottom of the chip removal channel, and the two sides of the chip removal plate along the width direction of the chip removal channel are respectively in contact with the two sides of the chip removal channel along the width direction.

[0017] The chip removal plate is hollow inside and has several filter holes arranged in an array on its upper inclined surface. There is a distance between the lower wall of the bottom filter hole and the bottom of the chip removal plate. A pipe assembly is installed inside the chip removal support.

[0018] Furthermore, the pipeline assembly includes negative pressure pipelines and positive pressure pipelines. The negative pressure pipeline includes a negative pressure main pipe, one end of which extends out of the chip removal bracket and is connected to a negative pressure pump. The other end of the negative pressure main pipe is provided with two negative pressure branch pipes, which are respectively connected to two chip removal plates.

[0019] The positive pressure pipeline includes a positive pressure main pipe, one end of which extends out of the chip removal bracket and is connected to a positive pressure pump. A positive pressure branch pipe is installed between the two chip removal plates, and the other end of the positive pressure main pipe is connected to the positive pressure branch pipe.

[0020] Furthermore, a pneumatic vibrator is installed at the connection between the main positive pressure pipe and the branch positive pressure pipe.

[0021] Compared with the prior art, the beneficial effects of this invention are as follows:

[0022] In this solution, the waste chips and cutting fluid generated during CNC machining fall into the chip removal channel and are temporarily stored there. Then, a synchronous belt starts and drives the slide to move. Based on the magnetic coupling principle between the lower and upper strong magnets, the slide moves along with the chip removal assembly, achieving chip removal simultaneously. Specifically:

[0023] a. Since the chip removal plate and the chip removal bracket are slidably connected and a spring is provided at the connection, the chip removal plate adapts to the curvature of the bottom of the chip removal channel and moves within the chip removal channel. The bottom of the chip removal plate is always in contact with the bottom of the chip removal channel. The significance of this is that the bottom of the chip removal channel is curved, which is to temporarily store cutting fluid and achieve separation between the waste chips and the cutting fluid during subsequent chip removal.

[0024] Furthermore, the magnetic coupling traction method not only allows the slide to move along with the chip removal bracket, but also the magnetic attraction force can make the bottom of the chip removal bracket fit tightly with the bottom of the chip removal channel, with no gaps between them. The significance of this is that the tight fit between the chip removal plate, the chip removal bracket, and the chip removal channel is to remove chips more thoroughly and to prevent waste chips from getting into gaps and causing damage to the chip removal structure.

[0025] b. When the chip removal bracket moves, the negative pressure pump starts. The outlet of the negative pressure pump is connected to a storage tank. Therefore, the cutting waste fluid in the chip removal channel flows into the storage tank through the filter hole, chip removal plate, and negative pressure pipe.

[0026] At the same time, the negative pressure can cause the waste chips in the chip removal channel to be adsorbed onto the surface of the chip removal plate. Furthermore, it can make the extension direction of the waste chips roughly perpendicular to the length direction of the chip removal channel. Some waste chips detach from the contact with the bottom of the chip removal channel. Although some waste chips do not detach from the contact with the bottom of the chip removal channel, the gripping force between the waste chips and the bottom of the chip removal channel is also greatly weakened. Therefore, when the chip removal plate moves, it can more smoothly and easily remove the waste chips in the chip removal channel and push the waste chips to the output channel. The noise generated in this process is small and the wear on the chip removal channel and chip removal plate is small.

[0027] c. When the waste is pushed to the output channel, the negative pressure pump stops and the positive pressure pump starts, blowing the waste out. The waste falls into the output channel and is guided outward through the output channel. During this process, the pneumatic vibrator can make the chip removal plate vibrate. The vibration combined with the positive pressure can make the waste more easily detach from the chip removal plate. Attached Figure Description

[0040] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0041] This solution achieves multi-directional chip removal by setting up multiple chip removal channels. At the same time, the optimized design of the chip removal structure makes the output of chips smoother, avoids chip blockage, and reduces the failure rate. In addition, the multi-directional chip removal structure can effectively reduce the accumulation of chips generated during the processing, improve the processing quality of parts, and reduce processing costs.

[0042] Reference Figures 3-10 A CNC machining center with a multi-directional chip removal structure includes a bed, a worktable 100, and a CNC machining system. All three are components of existing CNC machine tools and will not be described in detail.

[0043] The machine bed is equipped with an outer guide platform 101 surrounding the worktable 100. The worktable 100 is generally rectangular in shape. Therefore, the outer guide platform 101 is annular in shape and has a rectangular horizontal cross-section. Among the four inner walls of the outer guide platform 101, the distance between the two inner walls along the width direction and the distance between the two inner walls along the length direction are both vertical and increase from bottom to top.

[0044] The outer surface of the worktable 100 is provided with an inner guide platform 102. The distance between the two sides of the inner guide platform 102 along the width direction is vertical and decreases from bottom to top. The two sides of the inner guide platform 102 along the length direction are each composed of two inclined surfaces. The distance between the two inclined surfaces is also vertical and decreases from bottom to top, and the distance direction is parallel to the width direction of the worktable 100.

[0045] Therefore, the waste chips and cutting fluid generated during CNC machining of the workpiece can be drawn by existing technology and guided by the sides of the inner guide table 102 and the outer guide table 101 to fall into the area between them. The bottom of the area between them is open. The two sides of the inner guide table 102 along the length direction are respectively connected to the two inner walls of the outer guide table 101 along the length direction. Therefore, the open bottom between them is composed of two non-communicating openings. Furthermore, each opening is provided with a chip removal component 200 to guide the waste chips and cutting fluid away.

[0046] Reference Figures 5-10 The chip removal component 200 includes a chip removal channel 201. The upper end of the chip removal channel 201 is open and connected to the opening at the bottom of the area between the inner guide platform 102 and the outer guide platform 101. Therefore, waste chips and cutting fluid fall into the chip removal channel 201.

[0047] Each end of the chip removal channel 201 is provided with an output channel 202 tilted downwards. The bottom of the chip removal channel 201 is set in an arc shape and the arc is curved upwards. Its purpose is to receive and temporarily store cutting waste fluid.

[0048] A chip removal assembly 204 is provided in the chip removal channel 201, and a drive assembly 203 is provided below the chip removal channel 201. The drive assembly 203 is used to drive the chip removal assembly 204 to reciprocate within the chip removal channel 201. While the chip removal assembly 204 is moving, it draws in the cutting fluid in the chip removal channel 201 under negative pressure and pushes the chips into the output channel 202.

[0049] Reference Figure 6 The drive assembly 203 includes a drive bracket and a synchronous belt 2031 mounted on the drive bracket with its conveying direction parallel to the length direction of the chip removal channel 201. A slide block 2032 is slidably mounted on the drive bracket along the length direction of the chip removal channel 201. The slide block 2032 is connected to the synchronous belt 2031. By running or reversing the synchronous belt 2031, the slide block 2032 is moved or reversed, realizing the reciprocating movement of the slide block 2032 along the length direction of the chip removal channel 201. A lower strong magnet 2033 is provided on the upper surface of the slide block 2032, and the slide block 2032 moves together with the lower strong magnet 2033.

[0050] Reference Figure 8 and Figure 9The chip removal assembly 204 includes a chip removal bracket 205. Further, the chip removal bracket 205 includes two inclined plates 2051. The distance between the two inclined plates 2051 is parallel to the length direction of the chip removal channel 201. The distance between the two inclined plates 2051 decreases vertically from bottom to top. Each of the two inclined plates 2051 has a side plate 2052 on both sides along the width direction of the chip removal channel 201. The two side plates 2052 respectively fit against the two sides of the chip removal channel 201 along the width direction. Preferably, the two side plates... A base is provided between the bottoms of 2052, and a rotating roller 2053 is rotatably mounted on the bottom of the base. The axis of the rotating roller 2053 is parallel to the width direction of the chip removal channel 201. The rotating roller 2053 is supported by the bottom of the chip removal channel 201. Its significance is that the rotating roller 2053 enables the chip removal bracket 205 to form a rolling fit with the chip removal channel 201, so that the movement of the chip removal bracket 205 in the chip removal channel 201 is more stable and smooth. At least two rotating rollers 2053 are provided along the length direction of the chip removal channel 201.

[0051] The bottom of the base is also equipped with an upper strong magnet 2054, which is located above the lower strong magnet 2033. The magnetic force between the two is a magnetic attraction force. Based on the principle of magnetic coupling, the movement of the slide 2032 can move the chip removal bracket 205 together.

[0052] Each inclined plate 2051 is provided with a chip removal plate 206. Specifically, each of the two inclined plates 2051 has a protrusion on its opposite side. The chip removal plate 206 is also inclined, and the inclination direction of the chip removal plate 206 is parallel to the inclination direction of the corresponding inclined plate 2051. The upper inclined surface of the chip removal plate 206 is in contact with the lower inclined surface of the inclined plate 2051. A guide rod extends vertically from the upper end of the chip removal plate 206. The guide rod is slidably connected to the protrusion. A spring 207 is sleeved on the outside of the guide rod and located between the protrusion and the chip removal plate 206. Initially, under the elastic force of the spring 207, the bottom of the chip removal plate 206 contacts the bottom of the chip removal channel 201. In addition, the two sides of the chip removal plate 206 along the width direction of the chip removal channel 201 are respectively in contact with the two sides of the chip removal channel 201 along the width direction.

[0053] The chip removal plate 206 is hollow inside and has a number of filter holes arranged on its upper inclined surface. There is a distance between the lower wall of the bottom filter hole and the bottom of the chip removal plate 206.

[0054] Reference Figure 10 The chip removal bracket 205 is equipped with a pipe assembly. Further, the pipe assembly includes a negative pressure pipe 208 and a positive pressure pipe. The negative pressure pipe 208 includes a negative pressure main pipe. One end of the negative pressure main pipe extends out of the chip removal bracket 205 and is connected to a negative pressure pump. The other end of the negative pressure main pipe is equipped with two negative pressure branch pipes, which are respectively connected to two chip removal plates 206.

[0055] The positive pressure pipeline includes a positive pressure main pipe 209, one end of which extends out of the chip removal bracket 205 and is connected to a positive pressure pump. A pneumatic vibrator 210 is installed at the other end of the positive pressure main pipe 209. A positive pressure branch pipe 211 is installed between the two chip removal plates 206. The exhaust end of the pneumatic vibrator 210 is connected to the positive pressure branch pipe 211. Negative pressure pumps and positive pressure pumps are not shown in the figure.

[0056] The chip removal process of this invention is specifically manifested as follows:

[0057] The waste chips and cutting fluid generated during the CNC machining of the workpiece are drawn by existing technology and guided by the sides of the inner guide table 102 and the outer guide table 101, falling into the chip removal channel 201 and being temporarily stored in the chip removal channel 201.

[0058] Synchronous belt 2031 starts and drives slide 2032 to move. Based on the magnetic coupling principle between lower strong magnet 2033 and upper strong magnet 2054, slide 2032 moves together with chip removal bracket 205. During the movement:

[0059] a. Since the chip removal plate 206 and the chip removal bracket 205 are slidably connected and a spring 207 is provided at the connection, the chip removal plate 206 adapts to the curvature of the arc-shaped bottom of the chip removal channel 201 and moves within the chip removal channel 201, and the bottom of the chip removal plate 206 is always in contact with the bottom of the chip removal channel 201.

[0060] b. As the chip removal bracket 205 moves, the negative pressure pump starts. The outlet of the negative pressure pump is connected to a storage tank. Therefore, the cutting fluid in the chip removal channel 201 flows into the storage tank through the filter holes, chip removal plate 206, and negative pressure pipe 208. Simultaneously, the negative pressure causes the chips in the chip removal channel 201 to be adsorbed onto the surface of the chip removal plate 206. Furthermore, the extension direction of the chips is approximately perpendicular to the length direction of the chip removal channel 201. Some chips detach from the contact with the bottom of the chip removal channel 201. While some chips do not detach from the contact with the bottom of the chip removal channel 201, the gripping force between the chips and the bottom of the chip removal channel 201 is also affected. The significant weakening, this weakening of contact or hooking, is due to the distance between the filter holes and the bottom of the chip removal channel 201. The negative pressure will give the waste chips an upward force. Therefore, when the chip removal plate 206 moves, it can more smoothly and easily remove the waste chips in the chip removal channel 201 and push the waste chips to the output channel 202. At this time, the chip removal plate 206 stops moving, the negative pressure pump stops, the positive pressure pump starts, and blows the waste chips out. The waste chips fall into the output channel 202 and are guided outward through the output channel 202. The pneumatic vibrator 210 can make the chip removal plate 206 vibrate. The vibration combined with the positive pressure can make the waste chips detach from the chip removal plate 206 more smoothly.

[0061] Then, the synchronous belt 2031 pulls the chip removal plate 206 to move in the opposite direction, repeating the above operation to achieve the next chip removal action.

[0062] It should be noted that in this solution, the sliding block 2032 moves together with the chip removal bracket 205 based on the magnetic coupling principle between the lower strong magnet 2033 and the upper strong magnet 2054. In addition to the movement, the magnetic attraction force can also make the bottom of the chip removal bracket 205 fit tightly with the bottom of the chip removal channel 201, with no gap between them, so that the process of pushing the waste chips to the output channel 202 is more stable and smooth.

[0063] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
