Description

Technical Field

[0001] The present application relates to the field of machine tool waste chip processing, and in particular to a chip removal device. Background Art

[0002] Machine tools generate a large amount of waste chips of varying sizes during workpiece machining. If these chips are not promptly processed and accumulate on the machine tool, they will affect its normal operation. Simultaneously, the machine tool sprays a large amount of cutting fluid onto the workpiece during machining to improve machining quality. To centrally collect and separate the cutting fluid and waste chips, allowing for the fluid to be recycled, the machine tool is equipped with a chip removal device.

[0003] For example, in the chip removal device with the existing announcement number CN110000600A, waste chips and cutting fluid flow together to the chain plate chip conveyor, so that the waste chips remain on the chain plate, while the cutting fluid flows to the bottom of the chip conveyor box and flows to the water tank on the side. The cutting fluid is then filtered through two layers of filter screens and pumped back to the machine tool by a circulation pump for reuse.

[0004] Regarding the above-mentioned related technologies, some smaller waste chips can easily pass through the chain plate of the chip conveyor and deposit at the bottom of the chip conveyor box. Therefore, the chip conveyor needs to be cleaned regularly, and each cleaning requires the chip conveyor and the machine tool to be shut down synchronously, which makes the normal use time of the machine tool be squeezed. Summary of the Invention

[0005] In order to prevent the normal use time of the machine tool from being greatly squeezed, the present application provides a chip removal device.

[0006] The chip removal device provided in this application adopts the following technical solution.

[0007] A chip removal device includes a chip conveyor box for receiving waste chips and cutting fluid discharged by a machine tool, a chip conveyor body arranged in the chip conveyor box and capable of transporting waste chips, and a circulation mechanism arranged on one side of the chip conveyor box and pumping the cutting fluid back to the machine tool for recycling. The bottom surface of the chip conveyor box is slidably connected to a chip pusher plate for pushing waste chips into the circulation mechanism, and both ends of the chip pusher plate are fitted with end plates that keep the waste chips on the side of the chip pusher plate close to the circulation mechanism. The chip conveyor box is provided with a chip pushing motor that can drive the chip pusher plate to move.

[0008] By adopting the above technical solution, after a certain amount of waste chips accumulates at the bottom of the chip conveyor box, the chip pusher plate can move to push the accumulated waste chips in the chip conveyor box into the circulation mechanism, so that the waste chips in the chip conveyor box can be cleaned in time, and there is no need to disassemble the chip conveyor box from the bottom of the machine tool, so as to reduce the shutdown frequency of the chip conveyor body and the machine tool, so that the normal use time of the machine tool is not easily occupied.

[0009] Optionally, both ends of the chip pusher plate are provided with plate sliders, the plate sliders are slidably connected to the inner wall of the chip conveyor box, and the chip conveyor box is rotatably connected to a slider screw threadedly connected to the plate slider, and the slider screw is driven to rotate by the chip pusher motor.

[0010] By adopting the above technical solution, the chip pusher can move stably.

[0011] Optionally, the chip pusher plate is rotatably connected to the plate slider, and the chip pusher plate is coaxially fixedly connected to the plate gear. Box racks can be engaged on opposite sides of the plate gear to enable the chip pusher plate to flip over. The two box racks are located one-to-one on both sides of the chip conveyor box. The chip conveyor box is provided with a rack electric cylinder that enables the box rack to be away from the plate gear. A rotation limiter is provided between the plate slider and the chip conveyor box to enable the chip pusher plate to maintain a fixed position.

[0012] By adopting the above technical solution, after the chip pusher plate pushes the waste chips into the circulation mechanism, the chip pusher plate is flipped over so that there is a gap between the chip pusher plate and the bottom surface of the chip conveyor box. The chip pusher plate is then reset, so that during the reset process, the chip pusher plate is not likely to concentrate the newly fallen waste chips to the position where the chip pusher plate cannot be pushed into the circulation mechanism, further reducing the frequency of cleaning the chip conveyor box.

[0013] Optionally, the rack electric cylinder power rod is provided with a rack frame for connecting two box racks to drive the box racks to move, the rack frame is provided with a guide rod, and the inside of the chip conveyor box is provided with a guide sleeve for the guide rod to be inserted and slided.

[0014] By adopting the above technical solution, the two box racks can move synchronously to better adapt to the process of flipping the chip pusher plate and reduce the setting of related structures for the movement of the box racks.

[0015] Optionally, the pusher plate is provided with a leak-proof disc that can fit on the end plate and prevent cutting fluid from passing through the opening of the end plate.

[0016] By adopting the above technical solution, even if cutting fluid flows to the end of the pusher plate, it will be blocked by the leak-proof disc, making it difficult for cutting fluid to flow into the opening of the end plate where the pusher plate and the plate gear are connected.

[0017] Optionally, the chip conveyor box is slidably connected to a curved plate that can be rotated and engaged with the chip pusher plate. A compression spring is provided on the side of the curved plate away from the chip pusher plate to force the curved plate to move toward the chip pusher plate. The chip pusher plate is in contact with the side of the curved plate in an arc shape. The upper part of the curved plate is formed with an abutment plane that can abut the chip pusher plate. The lower side of the curved inner wall of the curved plate is engaged with the bottom inner wall of the chip conveyor box.

[0018] By adopting the above technical solution, the chip pusher plate can first abut against the arc plate when it is reset, so that when the chip pusher plate rotates to abut against the bottom surface of the chip conveyor box, it is not easy for waste chips to exist on the side of the chip pusher plate away from the circulation mechanism, so that the chip pusher plate can effectively send the waste chips accumulated at the bottom of the chip conveyor box into the chip conveyor box, and it is not easy for waste chips to accumulate in the chip conveyor box. It also makes it difficult for the chip pusher plate to effectively abut against the arc plate, and the arc surface where the arc plate connects to the bottom of the chip conveyor box should be under greater pressure and easily damaged.

[0019] Optionally, the rotation limiting part includes a fixed inclined wedge fixedly connected to the inside of the chip conveyor box, a dynamic inclined wedge slidably connected to the plate slider and capable of being moved by the fixed inclined wedge, a shaft end gear coaxially fixedly connected to the rotation point of the chip pusher plate, a rotation limiting rack fixedly connected to the dynamic inclined wedge and capable of engaging with the shaft end gear, and a rotation limiting spring arranged in the plate slider and forcing the rotation limiting rack to move toward the shaft end gear.

[0020] By adopting the above technical solution, when the chip pusher moves to the position where it needs to rotate, the dynamic inclined wedge abuts against the fixed inclined wedge, so that the dynamic inclined wedge is forced to move, so that the rotation limiting rack is away from the shaft end gear, and the chip pusher can now rotate smoothly.

[0021] Optionally, the chip pusher plate includes a center plate rotatably connected to the plate slider, two sleeve plates corresponding to each other and always sleeved and slidably connected on opposite sides of the center plate, and a sleeve spring is provided in the sleeve plate to force the sleeve plate away from the center plate, and the bottom of the chip conveyor box is connected to the circulation mechanism.

[0022] By adopting the above technical solution, when the chip pusher plate returns to contacting the inner bottom surface of the chip conveyor box, even if waste chips are stuck in the position where the sleeve plate and the inner bottom surface of the chip conveyor box are in contact, the sleeve plate will not easily cause large pressure on the chip conveyor box, and when the chip pusher plate moves to the position where the chip conveyor box is connected to the circulation mechanism, the waste chips originally stuck between the chip conveyor box and the sleeve plate will enter the circulation mechanism, so that the sleeve plate returns to normal.

[0023] Optionally, the circulation mechanism includes a water tank connected to the chip conveyor box and receiving the cutting fluid, a filter screen provided in the water tank and filtering the cutting fluid, a circulation pump provided in the water tank and pumping the filtered cutting fluid, and a baffle located between the filter screen and the circulation pump is provided on the bottom surface of the water tank.

[0024] By adopting the above technical solution, when waste debris enters the water tank due to damage to the filter or improper operation during filter replacement, the waste debris is deposited on the side of the water tank where the filter is set due to the presence of the baffle, making it difficult for the circulating pump to pump the waste debris.

[0025] Optionally, the water tank is provided with a plurality of filter openings for plugging filters.

[0026] By adopting the above technical solution, when there is a certain amount of waste chips on the filter screen that needs to be cleaned, the spare filter screen can be inserted into the unused filter screen port first, and then the filter screen that needs to be cleaned can be taken out. For this purpose, there is no need to shut down the chip conveyor body and the machine tool, which helps to increase the normal use time of the machine tool.

[0027] In summary, this application has at least one of the following beneficial effects:

[0028] 1. The waste chips in the chip conveyor box can be cleaned in time without removing the chip conveyor box from the bottom of the machine tool, thereby reducing the downtime of the chip conveyor body and the machine tool, making it less likely that the normal use time of the machine tool will be squeezed out;

[0029] 2. During the resetting process, the chip pusher plate is not likely to concentrate the newly fallen waste chips to a position where the chip pusher plate cannot be pushed into the circulation mechanism, further reducing the frequency of cleaning the chip conveyor box.

[0035] The present application is further described in detail below with reference to the accompanying drawings.

[0036] The present application discloses a chip removal device, referring to Figure 1 and Figure 2 , including a chip conveyor box 1 detachably connected to the bottom of the machine tool, a chip conveyor body 2 is installed in the middle and upper part of the chip conveyor box 1, and the chip conveyor body 2 can be a chain plate that can be circulated, so that when the cutting fluid mixed with waste chips falls onto the chip conveyor body 2 through the opening on the upper surface of the chip conveyor box 1, the large volume of waste chips can be transported away by the chip conveyor body 2, and a liquid collection port 26 is provided at the middle and lower part of the chip conveyor box 1, and a mechanism groove 27 connected to the lower end opening of the liquid collection port 26 is provided in the chip conveyor box 1. The length direction of the mechanism groove 27 is consistent with the length direction of the chip conveyor box 1, and small volume of waste chips will flow to the mechanism groove 27 along with the cutting fluid through the liquid collection port 26. A circulation mechanism 3 is installed just below the bottom of one side in the length direction of the chip conveyor box 1. A lower liquid port 36 is opened through the bottom of the chip conveyor box 1 just above the circulation mechanism 3. The upper end opening of the lower liquid port 36 is connected to the bottom surface of the mechanism groove 27. The circulation mechanism 3 pumps the cutting fluid in the chip conveyor box 1 back to the machine tool.

[0037] Reference Figure 2Two vertical end plates 5 are fixedly connected between the bottom and top surfaces of the mechanism slot 27. The length direction of the end plates 5 is consistent with the width direction of the chip conveyor box 1. The projection of the liquid collecting port 26 on the bottom surface of the chip conveyor box 1 is located between the two end plates 5. The length of the lower liquid port 36 is greater than the length between the two end plates 5. A common chip pusher plate 4 is slidably connected between the two end plates 5 along the width direction of the chip conveyor box 1. The chip pusher plate 4 includes a center plate 45. A rotating shaft 34 is integrally formed at the center of each end surface of the center plate 45 in the length direction. The axis direction of the rotating shaft 34 is consistent with the length direction of the center plate 45. Both end plates 5 are provided with a plate opening 35 along their own length direction. The length direction of the plate opening 35 is consistent with the length direction of the end plates 5. Each plate opening 35 is for a nearby rotating shaft 34 to pass through. A leak-proof disc 41 attached to the end plate 5 is fixedly connected to the side surface of the end of the center plate 45 , so that the cutting fluid is not easy to flow along the center plate 45 through the plate opening 35 into the opposite sides of the two end plates 5 .

[0038] Reference Figure 2 A plate slider 52 is slidably connected to the inner wall at both ends of the mechanism slot 27 in the longitudinal direction. The plate slider 52 moves along the width direction of the chip conveyor box 1. Each rotating shaft 34 is driven by a nearby plate slider 52 to move. Two slider screws 53 are rotatably connected to the chip conveyor box 1. The length direction of the slider screws 53 is consistent with the width direction of the chip conveyor box 1. The slider screws 53 pass through and are threadedly connected to the plate slider 52. Two chip pusher motors 51 are fixedly connected to the outside of the chip conveyor box 1. The output shaft of each chip pusher motor 51 is coaxially fixed to a slider screw 53, so that the center plate 45 can smoothly move along the width direction of the chip conveyor box 1.

[0039] Reference Figure 3The rotating shaft 34 is rotatably connected to the corresponding plate slider 52, so that when the center plate 45 is located directly above the lower liquid port 36, it is flipped at an angle within 90°, and the center plate 45 is transformed from a vertical state to a state close to horizontal, so that when the center plate 45 is reset, it is not easy to drive waste chips to a position away from the lower liquid port 36. A rotation limiting part 37 is provided between the plate slider 52 and the chip conveyor box 1 so that the chip pusher plate 4 can maintain a fixed position. The rotation limiting part 37 includes two fixed inclined wedges 38 fixedly connected to the upper surface of the inner part of the mechanism groove 27. The two fixed inclined wedges 38 are located one by one on both sides of the length direction of the chip conveyor box 1. The connection direction of the two fixed inclined wedges 38 is consistent with the width direction of the chip conveyor box 1. The upper surface of the plate slider 52 is slidably connected with a dynamic inclined wedge 39 in the vertical direction. The inclined surfaces at both ends of the dynamic inclined wedge 39 can be pushed vertically downward by the inclined surfaces of the two fixed inclined wedges 38 respectively. The bottom of the dynamic inclined wedge 39 is integrally formed with two vertical rack rods 24. The bottom end of the rack rod 24 is fixedly connected to a horizontal rotation limiting rack 22, and the rotation limiting rack 22 is slidably connected to the inside of the plate slider 52 along the vertical direction. The rotating shaft 34 is coaxially fixedly connected to the shaft end gear 21 located inside the plate slider 52, and the limiting rack 22 can engage with the shaft end gear 21. The bottom of the plate slider 52 is fixedly connected to a limiting spring 23 that can push the limiting rack 22 toward the shaft end gear 21.

[0040] When the center plate 45 moves to a position where waste chips enter the lower liquid inlet 36, the center plate 45 continues to move forward, causing the dynamic wedge 39 to contact the fixed wedge 38, causing the dynamic wedge 39 to move vertically downward, thereby moving the rotation-limiting rack 22 away from the shaft-end gear 21, and the center plate 45 can now rotate smoothly. When the center plate returns to a position away from the lower liquid inlet 36, the dynamic wedge 39 will abut the fixed wedge 38 away from the lower liquid inlet 36, and the center plate 45 can also rotate smoothly to return to its vertical position.

[0041] Reference Figure 2 and Figure 3 A plate gear 54 is coaxially fixedly connected to one end of the rotating shaft 34 near the plate slider 52. A rack rack 57 that moves in the vertical direction is provided in the mechanism slot 27. Vertical guide rods 58 are fixedly connected to the upper and lower portions of the rack rack 57. Each guide rod 58 is tightly inserted into a guide sleeve 59, which is fixedly connected to the inner wall of the mechanism slot 27. A rack electric cylinder 56 with a vertical power rod is detachably connected to the outer wall of the chip conveyor box 1. The power rod of the rack electric cylinder 56 is detachably connected to the rack rack 57. The rack rack 57 is fixedly connected to two horizontal box racks 55. The two box racks 55 are located on both sides of the length of the chip conveyor box 1 in a one-to-one correspondence. The two box racks 55 can mesh with the upper and lower sides of the plate gear 54 in a one-to-one correspondence.

[0042] When the center plate 45 moves to the lower liquid port 36 and the rotation-limiting rack 22 moves away from the shaft-end gear 21, the center plate 45 continues to move forward, causing the plate gear 54 to engage with the higher box rack 55, causing the center plate 45 to flip from vertical to horizontal. The rack electric cylinder 56 then connects to an external power source to drive the two box racks 55 to move upward synchronously, causing the higher box rack 55 to move away from the plate gear 54. The center plate 45 then moves along the width direction of the chip conveyor box 1 to reset. When the center plate 45 moves to a position away from the lower liquid port 36, the rotation-limiting rack 22 moves away from the shaft-end gear 21, and the plate gear 54 engages with the lower box rack 55, causing the center plate 45 to turn vertical.

[0043] Reference Figure 4 The chip pusher plate 4 also includes two sleeve plates 46. A sleeve plate 46 is inserted and slidably connected on both sides of the center plate 45 in the length direction. A sleeve spring 47 is fixedly connected inside the sleeve plate 46 to force the sleeve plate 46 away from the center plate 45. An anti-slip strip 25 is fixedly connected to one end of the center plate 45 located in the sleeve plate 46 and the inner wall of the sleeve plate 46 opening. Two adjacent anti-slip strips 25 can abut against each other, making it difficult for the sleeve plate 46 to separate from the center plate 45. When the sleeve plate 46 is vertical and abuts against the bottom surface of the mechanism groove 27, the corresponding two anti-slip strips 25 abut against each other.

[0044] Reference Figure 4 The bottom surface of the mechanism slot 27 is slidably connected to a curved plate 42 along the width of the chip conveyor box 1. The center of the curved plate 42 is close to the lower liquid port 36, and the inner bottom of the curved plate 42 contacts the bottom surface of the mechanism slot 27. A vertical abutment plane 44 is formed on the upper portion of the curved plate 42, so that when the sleeve 46 is vertical, the higher sleeve 46 can abut against the abutment plane 44. This prevents the inner bottom of the curved plate 42 from being easily damaged by abutting against the lower sleeve 46. When the plate gear 54 engages with the lower rack 55, the nearly horizontal sleeve 46 abuts against the inner ring of the curved plate 42. This prevents waste chips from being located on the side of the vertical sleeve 46 away from the lower liquid port 36 during the subsequent rotation of the sleeve 46 toward the vertical position. The sleeve 46 is curved on the side away from the center plate 45, allowing the sleeve 46 to better fit the inner surface of the curved plate 42. A horizontal compression spring 43 is fixedly connected to a side of the arc plate 42 away from the lower liquid port 36 . The compression spring 43 can enable the arc plate 42 pushed by the sleeve plate 46 to move toward the lower liquid port 36 .

[0045] Reference Figure 1The circulation mechanism 3 includes a water tank 48 detachably connected to the lower portion of the chip conveyor box 1. Four filter openings 33 are defined on the vertical side of the water tank 48. Two of the filter openings 33 contain horizontal filters 49, which are located directly below the lower liquid inlet 36. The mesh size of the taller filter 49 is smaller than that of the shorter filter 49. The two taller filter openings 33 accommodate a smaller filter 49, while the two shorter filter openings 33 accommodate a larger filter 49. This allows spare filters 49 to be inserted into the unused filter openings 33 when waste chips need to be removed from the filters 49. A circulation pump 31 is detachably connected to the end of the water tank 48 away from the filters 49. A retaining bar 32 is fixedly attached to the bottom surface of the water tank 48. The retaining bar 32 is located between the filters 49 and the circulation pump 31, preventing waste chips from the side of the retaining bar 32 near the filters 49 from flowing into the circulation pump 31 along with the cutting fluid.

[0046] The chip removal device of the present embodiment operates as follows: cutting fluid mixed with waste chips flows into the chip conveyor body 2, where the cutting fluid and small-volume waste chips flow through the liquid collection port 26 to the mechanism slot 27. When waste chips accumulate to a certain level in the chip conveyor box 1, the chip pusher motor 51 is connected to an external power source, causing the chip pusher plate 4 to move toward the lower liquid port 36, allowing the accumulated waste chips to enter the lower liquid port 36 and fall onto the filter 49. The filtered cutting fluid flows on the bottom surface of the water tank 48 and passes through the barrier 32, which is then pumped by the circulation pump 31 to the machine tool for recycling.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
