[0002] During the process of machining parts by a machine tool, a large amount of cutting waste chips and cutting cooling waste liquid will be generated. These cutting waste chips and cutting cooling waste liquid usually accumulate in the chip receiving groove at the bottom of the machine tool, so that after the machine tool is used up, the staff can quickly clean and recycle the cutting waste chips and cutting cooling waste liquid. However, the existing chip receiving groove has a small accommodation space. When machining large parts or a large number of parts, in order to make room in the chip receiving groove, the staff needs to clean the inside of the chip receiving groove many times, which not only takes up the machining time of the machine tool, but also has a large labor intensity during the cleaning process of the chip receiving groove. Therefore, the working burden of workers is high and the working efficiency is low. Content of the Utility Model

[0003] The purpose of the utility model is to provide a chip receiving structure for a machine tool, which has the effect of automatically cleaning and recycling cutting waste chips and cutting cooling waste liquid.

[0008] A further setting of the present utility model is that: a protective cover surrounding and protecting the gear is fixedly arranged on the inner wall of the groove, and an opening for the gear to mesh with the rack is reserved at the top of the protective cover.

[0009] A further setting of the present utility model is that: the second driving component includes a pair of lead screws respectively rotatably arranged on both sides of the machine tool body, a pair of nuts respectively threadedly connected to the two lead screws, a pair of rollers two respectively rotatably connected to the nuts, rolling grooves respectively inclinedly opened on one side of the two U-shaped baffles and for the two rollers two to roll, a pair of sprockets one respectively fixedly connected to one end of the two lead screws, a sprocket two rotatably arranged on the side wall of the machine tool body and above the middle of the two sprockets one, a chain sleeved on the two sprockets one and the sprocket two, and a servo motor fixedly arranged on the side wall of the machine tool body and driving the sprocket two to rotate. The rolling grooves on the sides of the two U-shaped baffles are parallel to each other. The thread directions of the two lead screws are opposite, and the nuts on the two lead screws are respectively close to the upper and lower ends of the rolling grooves. The lead screws are horizontally located on the side of the limiting plate away from the machine tool body, and the two ends of the lead screws are respectively rotatably connected to the limiting plates on both sides of the U-shaped baffle.

[0010] A further setting of the present utility model is that: the sprocket one, the sprocket two, the chain and the servo motor are located on the back side of the machine tool body. Four connecting threaded cylinders are fixedly arranged around the sprocket two on the back side of the machine tool body.

The servo motor is fixedly installed on the side of the motor mounting plate away from the machine tool body, and the output end of the servo motor rotatably penetrates through the motor mounting plate and is connected to the sprocket two.

[0011] A further setting of the present utility model is that: a drain pipe communicating with the inside thereof is fixedly arranged on the outer side wall of the groove, and the drain pipe is located between the two partition plates. A switch valve is fixedly installed on the drain pipe.

[0012] A further setting of the present utility model is that: inclined plates are respectively fixedly arranged on both sides of the groove where the machine tool body is located, and the upper ends of the inclined plates are fixedly connected to the partition plates and the lower ends are close to the ends of the groove. A vertical end plate is detachably arranged at the end of the groove. A strip is respectively vertically fixedly arranged on both sides of the end plate. Insertion slots for the two strips to be inserted are opened on the inner wall of the groove close to its end.

[0013] A further setting of the present utility model is that: a plurality of support feet are fixedly arranged at the bottom of the groove.

[0014] The beneficial effects of the present utility model are as follows: By adopting the above technical solution, when the machine tool body processes parts, the generated cutting waste chips and cutting cooling waste liquid will naturally fall onto the U-shaped chip receiving plate below the machine tool body. At the same time, since the bottom of the U-shaped chip receiving plate is provided with filter holes, the cutting cooling waste liquid will pass through the filter holes and be collected in the waste liquid collection space formed by a pair of partition plates and the inner wall of the tank body. In this way, the cutting waste chips and the cutting cooling waste liquid are separated.

[0015] When the U-shaped chip receiving plate is full of cutting waste chips, first, the servo motor drives the second sprocket to rotate, so that the second sprocket drives the two first sprockets to rotate synchronously through the chain. Then, the lead screws respectively connected to the two first sprockets will rotate synchronously, and the nuts thereon will slide relative to the U-shaped baffle under the drive of the rotation. Since the roller two rotating on the nut rolls on the inclined rolling groove on the U-shaped baffle, under the sliding of the nut, the U-shaped baffle will slide up and down relative to the positioning groove of the limit plate. Also, because the two lead screws have opposite helix directions and the nuts on the two lead screws are respectively close to the upper and lower ends of the rolling groove, under the sliding of the two nuts in opposite directions, the U-shaped baffles on both sides of the machine tool body will respectively rise and fall, so as to open an exit on one side of the machine tool body for the cutting waste chips on the U-shaped chip receiving plate to leave, and close an entrance on the other side to prevent the cutting waste chips on the U-shaped chip receiving plate from returning to the machine tool body. Then, after the above U-shaped baffle has completed its lifting and lowering, the three-phase asynchronous motor will drive the gear to engage with the rack, so that the rack drives the U-shaped chip receiving plate to slide in the direction of the above exit. Finally, when half of the U-shaped chip receiving plate with cutting waste chips has left the exit, the clean half of the U-shaped chip receiving plate will naturally enter below the machine tool body from the above entrance. In this way, the effect of quickly cleaning the cutting waste chips below the machine tool body is achieved.

[0016] When the above U-shaped chip receiving plate has accumulated enough cutting waste chips again, the above servo motor will rotate in the reverse direction, so that the exits and entrances on both sides of the machine tool body are swapped. Then, the three-phase asynchronous motor will rotate in the reverse direction, so that the U-shaped chip receiving plate slides out the cutting waste chips below the machine tool from the exit. At the same time, the cutting waste chips brought out by the U-shaped chip receiving plate in the previous round will not only be blocked outside the machine tool body by the U-shaped baffle closing the entrance because the exit has become the entrance, but also be continuously pushed down from one end of the U-shaped chip receiving plate and fall into the tank under the sliding of the U-shaped chip receiving plate, thus achieving the effect of cleaning half of the U-shaped chip receiving plate and sending it back below the machine tool body.

[0017] The entire above-mentioned automatic cutting waste cleaning process can not only effectively separate the cutting coolant waste liquid from the cutting waste, so as to reduce the subsequent cutting waste cleaning and recycling steps, but also the automatic cleaning process is continuous, fast, highly efficient, and does not require suspending the machining work of the parts on the machine tool, thereby effectively ensuring the machining efficiency of the machine tool and reducing the workload of workers.

Among them, a protective cover 212 surrounding and protecting the gear 232 is fixedly provided on the inner wall of the groove body 21, and an opening for the gear 232 to mesh with the rack 231 is reserved at the top of the protective cover 212, which can prevent the cutting waste liquid collected between the two partitions 26 from affecting the rotation of the gear 232 and effectively ensure the transmission safety of the gear 232 and the rack 231.

[0030] Further, the second drive assembly 25 includes a pair of lead screws 251 respectively rotatably disposed on both sides of the machine tool body 1, a pair of nuts 252 respectively threadedly connected to the two lead screws 251, a pair of rollers two 253 respectively rotatably connected to the nuts 252, rolling grooves 254 respectively formed on one side of the two U-shaped baffles 24 and for the two rollers two 253 to roll, a pair of sprockets one 255 respectively fixedly connected to one end of the two lead screws 251, a sprocket two 256 rotatably disposed on the side wall of the machine tool body 1 and above the middle of the two sprockets one 255, a chain 257 sleeved on the two sprockets one 255 and the sprocket two 256, and a servo motor 258 fixed to the side wall of the machine tool body 1 and driving the sprocket two 256 to rotate. The rolling grooves 254 on the sides of the two U-shaped baffles 24 are parallel to each other, the thread directions of the two lead screws 251 are opposite, and the nuts 252 on the two lead screws 251 are respectively close to the upper and lower ends of the rolling grooves 254. The lead screws 251 are horizontally located on the side of the limiting plate 11 away from the machine tool body 1, and the two ends of the lead screws 251 are respectively rotatably connected to the limiting plates 11 on both sides of the U-shaped baffle 24.

[0031] Further, the sprocket one 255, the sprocket two 256, the chain 257 and the servo motor 258 are located on the back side of the machine tool body 1. Four connecting threaded cylinders 12 are fixedly arranged around the sprocket two 256 on the back side of the machine tool body 1. The four connecting threaded cylinders 12 are fixedly connected to the motor mounting plate 13 by screws, and the sprocket two 256 is located between the motor mounting plate 13 and the back side of the machine tool body 1. The servo motor 258 is fixedly installed on the side of the motor mounting plate 13 away from the machine tool body 1, and the output end of the servo motor 258 rotatably penetrates through the motor mounting plate 13 and is connected to the sprocket two 256. By adopting the above-mentioned connecting threaded cylinders 12 and the motor mounting plate 13, not only can the servo motor 258 be stably installed and fixed, but also it is convenient for the staff to disassemble and repair components such as the sprocket two 256, the chain 257 and the servo motor 258.

[0032] Furthermore, inclined plates 14 are fixedly arranged on both sides of the trough body 21 of the machine tool body 1 respectively. The upper ends of the inclined plates 14 are fixedly connected to the partition plates 26, and the lower ends are close to the ends of the trough body 21. A vertical end plate 3 is detachably arranged at the end of the trough body 21. On both sides of the end plate 3, a strip 31 is vertically and fixedly arranged respectively. Slots 15 for inserting the two strips 31 are formed on the inner wall of the trough body 21 near its end. By adopting the above-mentioned inclined plates 14 and the detachable end plate 3, it is convenient for the staff to clean and recycle the cutting waste chips collected by the trough body 21.

[0033] Furthermore, a drain pipe 213 communicating with its interior is fixedly arranged on the outer side wall of the trough body 21, and the drain pipe 213 is located between the two partition plates 26. A switching valve 214 is fixedly installed on the drain pipe 213. It is convenient for the staff to discharge a part of the cutting cooling waste liquid collected between the two partition plates 26, thereby making room for collecting the cutting cooling waste liquid in subsequent machine tool processing.

[0034] Furthermore, a plurality of support feet 215 can be fixedly arranged at the bottom of the trough body 21, which can not only facilitate the transfer and installation of the trough body 21, but also indirectly raise the height of the drain pipe 213 so as to place a waste liquid collection container below the drain pipe 213.

[0035] The working principle of this embodiment:

[0036] When the machine tool body 1 processes parts, the generated cutting waste chips and cutting cooling waste liquid will naturally fall onto the U-shaped chip receiving plate 22 below the machine tool body 1. At the same time, since the bottom of the U-shaped chip receiving plate 22 is provided with filter holes 221, the cutting cooling waste liquid will pass through the filter holes 221 and gather in the waste liquid collection space formed by a pair of partition plates 26 and the inner wall of the trough body 21, thereby separating the cutting waste chips and the cutting cooling waste liquid in this way.

[0037] When the U-shaped chip receiving plate 22 is full of cutting waste chips, first, the servo motor 258 drives the second sprocket 256 to rotate, so that the second sprocket 256 drives the two first sprockets 255 to rotate synchronously through the chain 257. Then, the lead screws 251 respectively connected to the two first sprockets 255 will rotate synchronously, and drive the nuts 252 thereon to slide relative to the U-shaped baffle 24. Since the second rollers 253 rotating on the nuts 252 roll on the inclined rolling grooves 254 on the U-shaped baffle 24, under the sliding of the nuts 252, the U-shaped baffle 24 will slide up and down relative to the positioning groove 111 of the limit plate 11. Also, because the two lead screws 251 have opposite helix directions, and the nuts 252 on the two lead screws 251 are respectively close to the upper and lower ends of the rolling grooves 254, under the sliding of the two nuts 252 in opposite directions, the U-shaped baffles 24 on both sides of the machine tool body 1 will respectively move up and down, so as to open an exit on one side of the machine tool body 1 for the cutting waste chips on the U-shaped chip receiving plate 22 to leave, and close an entrance on the other side to prevent the cutting waste chips on the U-shaped chip receiving plate 22 from returning to the machine tool body 1. Then, after the above-mentioned U-shaped baffle 24 finishes moving up and down, the three-phase asynchronous motor 233 will drive the gear 232 to engage with the rack 231, so that the rack 231 drives the U-shaped chip receiving plate 22 to slide in the direction of the above-mentioned exit through the support plate 222. Finally, when half of the U-shaped chip receiving plate 22 with cutting waste chips leaves the exit, the clean half of the U-shaped chip receiving plate 22 will naturally enter under the machine tool body 1 from the above-mentioned entrance, and thus achieve the effect of quickly cleaning the cutting waste chips under the machine tool body 1 in this way.

[0038] When the above-mentioned U-shaped chip receiving plate 22 is full of enough cutting waste chips again, the above-mentioned servo motor 258 will rotate in the reverse direction, so that the exits and entrances on both sides of the machine tool body 1 are swapped. Then, the three-phase asynchronous motor 233 will rotate in the reverse direction, so that the U-shaped chip receiving plate 22 slides out of the cutting waste chips under the machine tool from the exit. At the same time, the cutting waste chips brought out by the U-shaped chip receiving plate 22 in the previous round will not only be blocked outside the machine tool body 1 by the U-shaped baffle 24 closing the entrance because the exit has become the entrance, but also will be continuously pushed down from one end of the U-shaped chip receiving plate 22 and fall into the tank body 21 under the sliding of the U-shaped chip receiving plate 22, so as to achieve the effect of cleaning half of the U-shaped chip receiving plate 22 and sending it back under the machine tool body 1.

[0039] The above-mentioned entire automatic cleaning process of cutting waste chips can not only effectively separate the cutting cooling waste liquid in the cutting waste chips to reduce the subsequent steps of cleaning and recycling the cutting waste chips, but also the automatic cleaning process is continuous, fast, efficient, and does not require pausing the part processing work of the machine tool, thus effectively ensuring the machining efficiency of the machine tool and reducing the work burden of the workers.
