[0004] During machining, the cutting tools and workpieces need to be cooled, and a lot of waste is generated during machining. Existing machining centers simply remove the waste without any corresponding treatment, which can easily affect the workshop environment. Summary of the Invention

[0005] In order to reduce the impact of machining center operations on the surrounding environment, this application provides a horizontal machining center.

[0006] The horizontal machining center provided in this application adopts the following technical solution:

[0007] A horizontal machining center includes a base and a chip removal device. The base has a slidably mounted worktable for fixing workpieces. The chip removal device includes a chip removal motor, a feeding screw, a waste chip crushing box, a powder storage box, and a liquid storage box. The chip removal motor is fixed to the base, and the base has a chip removal groove. The feeding screw is located within the chip removal groove, and its fixed end is connected to the chip removal motor. One end of the chip removal groove is located below the machining station of the machining center, and the bottom of the other end of the chip removal groove has a vertically oriented chip removal section. The feeding screw has its suspended end extending above the chip discharge port. The waste chip crushing box is located below the chip discharge port, with its inlet aligned with the chip discharge port of the base. The liquid storage tank is located below the waste chip crushing box, with a filter screen between them. The chip outlet of the waste chip crushing box is located above the filter screen, and the liquid inlet of the liquid storage tank is located below the filter screen. The powder storage box is located on one side of the liquid storage box, and the liquid storage box is equipped with a chip-pushing device that can move the waste chips on the filter screen into the powder storage box.

[0008] By adopting the above technical solution, the workpiece is fixed on the worktable, which slides on the base to transport the workpiece to the machining station. The cutting tool of the machining center processes the workpiece, while the cooling pipe sprays coolant onto the cutting tool and workpiece. The coolant and the waste chips generated during processing fall into the chip discharge trough. The chip discharge motor drives the feeding screw to rotate, transporting the waste chips and coolant in the chip discharge trough to the chip discharge port and into the waste chip crushing box. The waste chips are further crushed in the waste chip crushing box to form uniform particles or powder, which fall onto the filter screen. The coolant flows through the filter screen to the liquid storage tank for subsequent cooling. The chip pushing device pushes the waste chips on the filter screen into the powder storage box for recycling, reducing the impact on the external environment.

[0009] Preferably, a water pump body is fixed to the side wall of the liquid storage tank. The inlet of the water pump body is connected to the inner cavity of the liquid storage tank through a pipe. The outlet of the water pump body is connected to the cooling nozzle of the machining center through a pipe. A drive motor is also fixed to the side wall of the liquid storage tank. The output shaft of the drive motor is coaxially connected to the impeller of the water pump body.

[0010] By adopting the above technical solution, the drive motor rotates to drive the impeller to rotate, which in turn causes the water pump to run and transport the coolant in the storage tank to the cooling nozzle for cooling, thus realizing the recycling of the coolant.

[0011] Preferably, the waste crushing box includes a box body, in which a drive shaft and a driven shaft are rotatably arranged, the drive shaft and the driven shaft are arranged in parallel, the drive shaft is fixed with a drive crushing roller, the driven shaft is fixed with a driven crushing roller, both the drive crushing roller and the driven crushing roller have crushing teeth, a transmission component one is provided between the drive motor and the drive shaft, the drive motor can drive the drive shaft to rotate through the transmission component one, and a transmission component two is provided between the drive shaft and the driven shaft to enable the two to rotate synchronously.

[0012] By adopting the above technical solution, the drive motor drives the active shaft to rotate through the first transmission component, and the active shaft drives the driven shaft to rotate synchronously through the second transmission component, so that the active crushing roller and the driven crushing roller rotate synchronously, and the crushing teeth crush the waste in the waste crushing box.

[0013] Preferably, a stirring shaft is rotatably arranged in the inner cavity of the liquid storage tank, and stirring blades are fixed on the stirring shaft. The drive motor is connected to the stirring shaft through a transmission assembly three, and the drive motor can drive the stirring shaft to rotate through the transmission assembly three.

[0014] By adopting the above technical solution, the drive motor runs and the three drive stirring shafts rotate through the transmission assembly, so that the stirring blades stir the coolant in the storage tank, thereby improving the uniformity of the coolant in the storage tank and reducing sedimentation.

[0015] Preferably, the base is provided with a slide rail, the worktable is slidably disposed on the slide rail, the base is provided with a drive component capable of driving the worktable to slide along the slide rail, the chip removal groove is parallel to the slide rail, the worktable is provided with a cleaning collar, the cleaning collar is sleeved on the feeding screw, and the inner ring of the cleaning collar has a soft brush capable of contacting the feeding screw.

[0016] By adopting the above technical solution, the feeding screw may have a lot of waste chips adhering to it after feeding. After the workpiece on the worktable is processed, it slides from near the processing station toward the chip discharge port, which can drive the cleaning collar to move. The soft brush on the inner ring of the cleaning collar can clean the waste chips on the feeding screw.

[0017] Preferably, the chip conveying motor is fixed in the inner cavity of the base, and there is a connecting hole between the chip conveying groove and the inner cavity of the base. The feeding screw passes through the connecting hole and is connected to the output end of the chip conveying motor. There is a retaining ring around the connecting hole. The inner diameter of the cleaning collar is larger than the outer diameter of the retaining ring. When the worktable slides to the processing position, the cleaning collar is sleeved on the retaining ring.

[0018] By adopting the above technical solution, when the machining center is processing, the worktable slides to the machining station, and the cleaning collar is fitted onto the retaining ring, so that the soft brush of the inner ring of the cleaning collar is in contact with the outer ring of the retaining ring. When the feeding screw rotates, it will not rub against the soft brush, reducing the risk of soft brush wear, and at the same time avoiding the soft brush from affecting the normal feeding of the feeding screw.

[0019] Preferably, the workbench is equipped with a linear motor, the driving direction of which is parallel to the chip discharge groove. The output end of the linear motor is connected to the cleaning collar. The chip pushing device includes a chip pushing plate, a connecting rod, and a reset spring. The upper end of the connecting rod is slidably disposed on the chip discharge groove. The side of the cleaning collar near the chip discharge port can contact the upper end of the connecting rod and push the connecting rod to slide. The lower end of the connecting rod is connected to the chip pushing plate. The chip pushing plate is arranged in a horizontal direction and can slide above the filter screen. The reset spring is disposed between the connecting rod and the waste chip crushing box.

[0020] By adopting the above technical solution, when the worktable moves to a position close to the chip discharge port, the linear motor continues to push the cleaning collar towards the chip discharge port. During the movement of the cleaning collar, it can push the connecting rod to slide, causing the chip pusher plate to move and move the waste chips on the filter screen to the powder storage box for recycling.

[0021] Preferably, a partition plate is slidably provided at the chip inlet of the waste chip crushing box in the horizontal direction. An intermediate gear, an upper rack, and a lower rack are provided on the base. The upper rack is connected to the worktable and can mesh with the intermediate gear. The lower rack is connected to the partition plate and meshes with the intermediate gear. A storage box is provided on the side of the waste chip crushing box. The opening of the storage box faces upward and is lower than the partition plate. The partition plate can slide back and forth between the opening of the storage box and the chip inlet of the waste chip crushing box.

[0022] By adopting the above technical solution, when the machining center is in the machining state, the worktable is far from the chip discharge port, the upper rack does not mesh with the middle gear, and the partition plate is not located directly above the chip inlet, so that the chip inlet is in the open state. When the machining center finishes machining, when the worktable moves to the vicinity of the chip discharge port, the upper rack begins to mesh with the middle gear, and through the action of the lower rack, the partition plate moves, closing the chip inlet. A small amount of large-particle waste chips remain above the partition plate. Because it takes a long time to ensure uniform grinding when a small amount of waste chips enter the waste chip crushing box, the cost-effectiveness is low. Therefore, this part of the waste chips is left on the partition plate. When reprocessing, the worktable moves towards the machining station, and the partition plate can move back to the vicinity of the opening of the storage box. The large-particle waste chips can be pushed into the storage box manually or by an automatic pusher for testing or other uses.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Waste chips generated during machining at the machining center can be conveyed to the waste chip crushing box. The waste chips are further crushed in the waste chip crushing box to form uniform particles or powder and fall onto the filter screen. Coolant flows through the filter screen to the liquid storage tank for subsequent cooling. The chip pushing device pushes the waste chips on the filter screen to the powder storage tank for recycling, reducing the impact on the external environment. Attached Figure Description

The powder storage box 6 is located on one side of the liquid storage box 7, and a chip pushing device 11 is provided on the liquid storage box 7 to move the waste chips on the filter screen 10 into the powder storage box 6.

[0041] like Figure 4 , Figure 5 , Figure 6As shown, a water pump body 12 is fixed to the side wall of the storage tank 7.

The drive motor 13 is indirectly fixed to the storage tank 7 through the water pump body 12, and the output shaft of the drive motor 13 is coaxially connected to the impeller of the water pump body 12. The rotation of the drive motor 13 drives the impeller to rotate, causing the water pump body 12 to run and transport the coolant in the storage tank 7 to the cooling nozzle for cooling, thereby realizing the recycling of the coolant.

[0042] like Figure 3 , Figure 4 , Figure 5 As shown, the waste shredder 5 includes a box body, in which a drive shaft 14 and a driven shaft 15 are rotatably arranged. The drive shaft 14 and the driven shaft 15 are arranged in parallel. The drive shaft 14 is fixed with a drive crushing roller 16, and the driven shaft 15 is fixed with a driven crushing roller 17. Both the drive crushing roller 16 and the driven crushing roller 17 have crushing teeth. A transmission assembly 18 is provided between the drive motor 13 and the drive shaft 14. The drive motor 13 can drive the drive shaft 14 to rotate through the transmission assembly 18.

[0044] Alternatively, the transmission assembly 18 can be designed as a combination of multiple gears, with the drive motor 13 driving the drive shaft 14 to rotate through the gear combination.

[0045] like Figure 3 , Figure 4 , Figure 5 As shown, a transmission assembly 22 capable of synchronizing the rotation of the drive shaft 14 and the driven shaft 15 is provided between them.

[0046] In this embodiment, the transmission assembly 22 includes a driving gear 23 and a driven gear 24 that mesh with each other. The driving gear 23 is fixed on the driving shaft 14, and the driven gear 24 is fixed on the driven shaft 15.

The second driving pulley 28 is coaxially fixed on the output shaft of the drive motor 13. The first transmission shaft 31 is rotatably mounted on the liquid storage tank 7. The second driven pulley 29 is fixed on the first transmission shaft 31. The first driving bevel gear 32 is fixed on the first transmission shaft 31. The first driven bevel gear 44 is fixed on the stirring shaft 25 and meshes with the first driving bevel gear 32.

This causes the stirring blades 26 to stir the coolant in the storage tank 7, thereby improving the uniformity of the coolant in the storage tank 7 and reducing sedimentation.

[0051] As an alternative, transmission assembly 327 can also be designed as a combination of multiple gears or pulleys.

[0052] like Figure 2 , Figure 5 As shown, the chip removal groove 8 is parallel to the slide rail 3, and a cleaning collar 33 is provided on the worktable 2. The cleaning collar 33 is sleeved on the feeding screw 4, and the inner ring of the cleaning collar 33 has a soft brush that can contact the feeding screw 4.

[0053] Preferably, the chip conveying motor is fixed in the inner cavity of the base 1, and there is a connecting hole between the chip conveying groove 8 and the inner cavity of the base 1. The feeding screw 4 passes through the connecting hole and is connected to the output end of the chip conveying motor. There is a retaining ring 45 around the connecting hole. The inner diameter of the cleaning collar 33 is larger than the outer diameter of the retaining ring 45. When the worktable 2 slides to the processing position, the cleaning collar 33 is fitted onto the retaining ring 45.

[0054] like Figure 5As shown, the workbench 2 is equipped with a linear motor 34. The driving direction of the linear motor 34 is parallel to the chip discharge groove 8. The output end of the linear motor 34 is connected to the cleaning collar 33. The chip pushing device 11 includes a chip pushing plate 35, a connecting rod 36 and a reset spring 37. The upper end of the connecting rod 36 is slidably disposed on the chip discharge groove 8. The side of the cleaning collar 33 near the chip discharge port 9 can contact the upper end of the connecting rod 36 and push the connecting rod 36 to slide. The lower end of the connecting rod 36 is connected to the chip pushing plate 35. The chip pushing plate 35 is arranged in a horizontal direction and can slide above the filter screen 10. The reset spring 37 is disposed between the connecting rod 36 and the waste chip crushing box 5.

[0055] like Figure 5 , Figure 6 , Figure 7 As shown, a partition plate 38 is slidably installed at the inlet of the waste shredder 5 in the horizontal direction. An intermediate gear 39, an upper rack 40, and a lower rack 41 are provided on the base 1. The upper rack 40 is connected to the worktable 2 and can mesh with the intermediate gear 39. The lower rack 41 is connected to the partition plate 38 and meshes with the intermediate gear 39. A storage box 42 is provided on the side of the waste shredder 5. The opening of the storage box 42 faces upward and is lower than the partition plate 38. The partition plate 38 can slide back and forth between the opening of the storage box 42 and the inlet of the waste shredder 5.

[0056] The working principle of this embodiment is as follows: The workpiece is fixed on the worktable 2, which slides on the base 1 to transport the workpiece to the machining station. The cutting tool of the machining center processes the workpiece, and at the same time, the cooling pipe sprays coolant onto the cutting tool and the workpiece. At this time, the cleaning collar 33 is fitted onto the retaining ring, so that the soft brush of the inner ring of the cleaning collar 33 is in contact with the outer ring of the retaining ring. When the feeding screw 4 rotates, it will not rub against the soft brush. The coolant and the waste chips generated during processing fall into the chip discharge groove 8. The chip discharge motor drives the feeding screw 4 to rotate, and the chip discharge groove 8... The waste chips and coolant are conveyed to the chip discharge port 9 and fall into the waste chip crushing box 5. The active crushing roller 16 and the driven crushing roller 17 in the waste chip crushing box 5 rotate under the action of the drive motor 13 to crush the waste chips. The crushed waste chips remain on the filter screen 10. The coolant flows through the filter screen 10 to the storage chamber. The drive motor 13 drives the stirring paddle to rotate so that the coolant in the storage chamber is more uniform. The drive motor 13 can also drive the water pump body 12 to run, and deliver the coolant to the cooling nozzle of the machining center for recycling. After processing is completed, the worktable 2 moves to a position close to the chip discharge port 9. The linear motor 34 continues to push the cleaning collar 33 toward the chip discharge port 9. During the movement of the cleaning collar 33, the soft brush of the inner ring of the cleaning collar 33 can clean the waste chips on the feeding screw 4. When the worktable 2 is close to the chip discharge port 9, it can push the connecting rod 36 to slide, so that the chip pusher plate 35 moves and moves the waste chips on the filter screen 10 to the powder storage box 6 for recycling. At the same time, the upper rack 40 meshes with the intermediate gear 39 and gradually pushes the separator plate 38 to move until the separator plate 38 closes the chip inlet. A small amount of large particles of waste chips remain above the separator plate 38.

[0057] Example 2:

[0058] This embodiment is largely the same as Embodiment 1, except that, as Figure 8 As shown, in this embodiment, the base 1 has a drive motor 13 on only one side, but also has two sets of liquid storage tanks, waste crushing tanks, etc. The drive motor 13 can drive the driven shaft in one set of waste crushing tanks to rotate. The driven shaft drives the driven shaft in the other set of waste crushing tanks to rotate through the transmission assembly four. The drive assembly four includes a transmission shaft two, which is divided into two coaxial half shafts 43. The half shafts 43 are transmitted through multiple bevel gears to reduce the probability of torsional deformation caused by transmission when the half shafts 43 are long.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
