Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of chain plate type chip conveyors, in particular to a chain plate type chip conveyor and a numerically controlled machine tool having the same. Background Art
[0002] A chain-type chip conveyor is a device used to remove chips during machine tool processing. It primarily consists of a chain, a drive unit, a transmission system, and a frame. Its core function is to transport chips from the work area to a collection point, ensuring a clean machining environment and the proper functioning of the equipment.
[0003] In the prior art, in the process of chip removal on CNC lathes, it is necessary to cool the cutter head by water flow. Due to the differences in the types of cutting blades and cutter heads, the sizes of the chips generated by the cutter heads are also different. During the cyclic rotation and discharge of the chain plate chip conveyor, some chips will be carried by the water flow and flow toward the chip conveyor along the flow direction of the water flow. On the one hand, chips of different sizes will be stuck in the gaps of the chain plate chip conveyor, thereby causing the chip removal holes to be blocked. On the other hand, under the impact of the water flow, large chips will be impacted into the gaps, so that the large chips are stuck between the gaps of the chain plate chip conveyor, thereby affecting the normal circulation of water flow in the chip conveyor.
[0004] In order to solve the above problems, the existing technology usually uses a method of regular inspection and cleaning of debris. By knocking on the chain plate body on the chain plate chip conveyor, the debris can pass through the gaps in the chain plate body, thereby improving the cleaning efficiency of the chain plate chip conveyor. However, on the one hand, the manual cleaning process will occupy the normal working efficiency of the chain plate chip conveyor and also waste manpower; on the other hand, the manual knocking method can only shake part of the gap, and it is difficult to clean the entire chain plate chip conveyor.
[0005] Based on this, in order to solve the problem that during the chip removal process of CNC machine tools, the chips of different sizes may get stuck in the gap between the chain plate body and the chain plate body, thereby causing blockage, the present invention designs a chain plate chip conveyor and a CNC machine tool with the chain plate chip conveyor. Summary of the Invention
[0006] The present invention provides a chain plate type chip conveyor and a CNC machine tool with the chain plate type chip conveyor, which solves the problem that during the chip removal process of the CNC machine tool, the chips are stuck in the gap between the chain plate body and the chain plate body due to the different sizes of the chips, thereby causing blockage. During the chip removal process of the chain plate body, the power of the chain plate body circulation is used to automatically clean the iron chips between the chain plate bodies, and at the same time, the bottom chain plate body and the rear chain plate body are intermittently impacted, thereby forming a shaking cleaning effect.
[0007] In order to achieve the above object, the present invention provides the following technical solutions:
[0008] The present invention provides a chain plate type chip conveyor, which includes a frame, a driving device, a chain plate body, a scraper, a guide device, a movable plate and an adjustment plate. The driving device is installed on the frame, the chain plate body is installed on the driving device, the scraper is installed on the front of the chain plate body, the guide device is installed below the chain plate body, the movable plate is installed on the guide device, and the adjustment plate is located below the chain plate body. When the chain plate body rotates, the guide device drives the movable plate to move laterally, and the guide device drives the adjustment plate to intermittently shake the chain plate body.
[0009] When the chain plate moves, the adjusting plate moves up and down under the action of the guide device, shaking the chain plate at the bottom and side wall, thereby achieving intermittent cleaning of the gaps between the chain plates and the chain plate sieve holes.
[0010] Preferably, the driving device includes a motor, a sprocket, and a rotating shaft, wherein the motor is mounted on a frame, the sprocket is mounted on the end of the chain plate body, the rotating shaft is mounted on the sprocket, and a paddle is mounted on the rotating shaft, and the paddle is located on the side of the rotating shaft close to the sprocket. When the rotating shaft rotates, the paddle will intermittently knock on the chain plate, thereby achieving a vibration chip removal effect.
[0011] Preferably, a drain port is provided between the chain plate bodies, and the width of the drain port is smaller than the particle size of qualified chips. By providing the drain port, water can be discharged from the drain port, thereby improving the working efficiency of the chain plate type chip conveyor.
[0012] Preferably, the guide device includes a fixed plate, a return spring, a protrusion, a push plate, a mounting hole, a compression spring, and a limit block. The fixed plate is mounted on the frame, the return spring is mounted on the fixed plate, the protrusion is mounted on the other end of the return spring, the push plate is mounted below the chain plate body, the mounting hole is provided on the fixed plate, the compression spring is mounted in the mounting hole, the limit block is mounted in the mounting hole, the limit block is mounted on the other end of the compression spring, and the limit block is connected to the adjustment plate. The adjustment plate is mounted below the limit block. When the limit block moves downward, it will drive the adjustment plate to move downward, thereby colliding with the chain plate below and at the rear of the transport, thereby forming a shaking effect. On the one hand, it can enable the iron filings blocked by the scraper in the chain plate to be completely detached under the knocking and shaking at the end. On the other hand, it can prevent the iron filings from adhering to the gaps between the chain plate and the sieve holes. As the chain plate rotates, it gradually circulates, thereby improving the chip removal effect of the chain plate.
[0013] Preferably, the push plate is divided into a long plate and a short plate, and the long plate and the short plate are arranged in a staggered manner. The staggered arrangement of the long plate and the short plate increases the up and down reciprocating period of the limit block, and then the long plate drives the adjustment plate to intermittently collide with the side chain plate through the limit block.
[0014] Preferably, a wedge-shaped surface is provided at the end of the protrusion, and an inclined surface is provided at the end of one side along the length direction of the chain plate body.
[0015] Through the cooperation of the wedge surface and the inclined surface, the two can be smoothly tangent to each other, so that when the long plate moves, it can drive the convex block to compress, thereby improving the scraping efficiency of the movable plate on the chain plate gap.
[0016] Preferably, the chain plate body is provided with sieve holes arranged in an array along the length of the movable plate, and a collection box is provided at the end of the frame. The sieve holes are used to further circulate the water flow, and iron filings embedded in the sieve holes will fall into the collection box under the scraping of the movable plate and the impact of the adjustment plate, thereby completing collection.
[0017] Preferably, a guide plate is installed above the chain plate body, and the inner wall of the guide plate is a curved surface. The guide plate is used to guide the working iron chips to the chain plate body. The curved surface is more likely to form a collection, avoid splashing, and thus avoid the scattering of iron chips, thereby improving the centralized cleaning efficiency of iron chips.
[0018] A CNC lathe includes any one of the above-mentioned chain plate type chip conveyors, including a machine tool body, a cutting tool seat and a guard plate, wherein the machine tool body is located at the front end of the frame, the cutting tool seat is installed on the machine tool body, the cutting tool seat is located above the chain plate body, and the guard plate is installed above the cutting tool seat, and the guard plate corresponds to the guide plate.
[0019] A guard plate is added to the cutting tool seat so that the debris generated during work is blocked by the guard plate and falls into the collection box. Cooperating with the guide plate, it restrains the movement of flying iron chips, thereby ensuring that the iron chips can fall onto the chain plate, thereby improving the chain plate's effect on transporting and collecting iron chips.
[0020] The beneficial effects of the present invention are as follows:
[0021] 1. The present invention proposes a chain plate type chip conveyor. Under the action of the driving device, the chain plate body drives the scraper to circulate back and forth, and then the debris entering the top of the chain plate body is transported and discharged. The guide device is used to provide power support and starting parts for the movable plate and the adjustment plate. The movable plate cleans the gaps between the chain plates by moving horizontally, and the adjustment plate moves up and down under the action of the guide device when the chain plate moves, shaking the chain plates at the bottom and side walls, thereby realizing intermittent cleaning of the gaps between the chain plates and the chain plate sieve holes.
[0022] The camming plate is moved back and forth by the guide rails, and the guide rails are moved back and forth, thereby preventing the camming plate from being stuck in the gap between the chain plate and the sieve hole and the sieve hole from being blocked.
[0023] 3. The present invention proposes a CNC lathe, which adds a guard plate at the cutting tool seat, so that the debris generated during work is blocked by the guard plate and falls into the collection box. The guard plate cooperates with the guide plate to restrain the movement of flying iron chips, thereby ensuring that the iron chips can fall onto the chain plate, thereby improving the chain plate's effect on transporting and collecting iron chips.

DETAILED DESCRIPTION
[0035] In order to better understand the above solution, the above technical solution is described in detail below with reference to the accompanying drawings and specific implementation methods.
[0036] like Figure 1-2 As shown, the present invention provides a chain plate type chip conveyor, including a frame 1, a driving device 2, a chain plate body 3, a scraper 4, a guide device 5, a movable plate 6 and an adjustment plate 7. The driving device 2 is installed on the frame 1, the chain plate body 3 is installed on the driving device 2, the scraper 4 is installed on the front of the chain plate body 3, the guide device 5 is installed below the chain plate body 3, the movable plate 6 is installed on the guide device 5, and the adjustment plate 7 is located below the chain plate body 3. When the chain plate body 3 rotates, the guide device 5 drives the movable plate 6 to move horizontally, and the guide device 5 drives the adjustment plate 7 to intermittently shake the chain plate body 3.
[0037] The driving device 2 is used to drive the chain plate body 3 to circulate. Under the action of the driving device 2, the chain plate body 3 drives the scraper 4 to circulate back and forth, thereby conveying and discharging the debris that enters the top of the chain plate body 3. The guide device 5 is used to provide power support and starting parts for the movable plate 6 and the adjustment plate 7. The movable plate 6 cleans the gaps between the chain plates by moving horizontally, and the adjustment plate 7 moves up and down under the action of the guide device 5 when the chain plate moves, shaking the chain plates at the bottom and side walls, thereby realizing intermittent cleaning of the gaps between the chain plates and the chain plate sieve holes 32.
[0038] like Figure 3As shown, the driving device 2 includes a motor 21, a sprocket 22 and a rotating shaft 23. The motor 21 is installed on the frame 1, the sprocket 22 is installed at the end of the chain plate body 3, the rotating shaft 23 is installed on the sprocket 22, and a paddle 24 is installed on the rotating shaft 23. The paddle 24 is located on the side of the rotating shaft 23 close to the sprocket 22.
[0039] When the motor 21 rotates, the output shaft will drive the rotating shaft 23 to rotate, the rotating shaft 23 will drive the sprockets 22 at both ends to rotate, and the sprockets 22 will drive the chain plates engaged with them to rotate. At the same time, when the rotating shaft 23 rotates, the paddle 24 also rotates. The paddle 24 is made of rubber. When the rotating shaft 23 rotates, the paddle 24 will intermittently knock on the chain plates, thereby achieving the effect of vibration chip removal.
[0040] A drainage port 31 is provided between the chain plate bodies 3 , and the width of the drainage port 31 is smaller than the particle size of qualified chips.
[0041] During the chip removal process of the chain plate type chip conveyor, the cutter head needs to be cooled by water flow. If this part of the water flow accumulates inside the chip conveyor, it will cause rust on the iron chips and even form an oxide layer on the surface of the chain plate. By setting a drain port 31, the water flow can be discharged from the drain port 31, thereby improving the working efficiency of the chain plate type chip conveyor.
[0042] like Figure 4 、 5 As shown in Figures 6 and 7, the guide device 5 includes a fixed plate 51, a return spring 52, a protrusion 53, a push plate 54, a mounting hole 55, a compression spring 56, and a limit block 57. The fixed plate 51 is mounted on the frame 1, the return spring 52 is mounted on the fixed plate 51, the protrusion 53 is mounted on the other end of the return spring 52, the push plate 54 is mounted below the chain plate body 3, the mounting hole 55 is opened on the fixed plate 51, the compression spring 56 is mounted in the mounting hole 55, the limit block 57 is mounted in the mounting hole 55, the limit block 57 is mounted on the other end of the compression spring 56, and the limit block 57 is connected to the adjustment plate 7. The adjustment plate 7 is mounted below the limit block 57.
[0043] When the chain plate 32 is driven by the sprocket 22, the push plate 54 at the bottom of the chain plate moves synchronously, and the push plate 54 contacts the protrusion 53 on the fixed plate 51, thereby driving the push block to compress the return spring 52, and then disengage after compression. At this time, the return spring 52 is reset, thereby driving the movable plate 6 above the protrusion 53 to move back and forth, thereby scraping the inner surface of the chain plate, thereby preventing the sieve hole 32 and the drain outlet 31 from being blocked; at the same time, under the action of the push plate 54, the limit block 57 is driven to move downward along the mounting hole 55, thereby squeezing the compression spring 56, and when the limit block 57 moves downward, it drives the adjustment plate 7 to move downward, thereby hitting the chain plate below and behind the transport, thereby forming a shaking effect. On the one hand, it can make the iron chips blocked by the scraper 4 in the chain plate completely detached under the knocking and shaking when it reaches the end, and on the other hand, it can prevent the iron chips from adhering to the gap between the chain plate and the sieve hole 32. As the chain plate rotates, it gradually circulates, thereby improving the chip removal effect of the chain plate.
[0044] like Figure 7 As shown, the push plate 54 is divided into a long plate 541 and a short plate 542, which are arranged in a staggered manner. The staggered arrangement of the long plates 541 and the short plates 542 increases the up and down reciprocating period of the limit block 57. The long plate 541 drives the adjustment plate 7 through the limit block 57 to intermittently impact the side chain plate. The structure of the adjustment plate 7 is not limited here, and the impact angle of the adjustment plate 7 can be set as required to achieve the effect of cleaning the chain plate.
[0045] At the same time, the ends of the long plate 541 and the short plate 542 fit the chain plate, but the middle part is suspended, leaving space for the movable plate 6 to move, so that when the chain plate rotates, the scraper can intermittently scrape the back of the chain plate, thereby improving the cleaning effect of the chain plate gap.
[0046] like Figure 4 、 5 As shown, a wedge-shaped surface 531 is provided at the end of the protrusion 53 , and an inclined surface 5411 is provided at the end of one side along the length direction of the chain plate body 3 .
[0047] Through the cooperation of the wedge surface 531 and the inclined surface 5411, the two can be smoothly tangent to each other, so that the long plate 541 can drive the protrusion 53 to be compressed during the movement. After passing over the protrusion 53, the protrusion 53 is restored. At the same time, the compression is gradual, thereby driving the movable plate 6 to move gradually, thereby improving the scraping efficiency of the movable plate 6 on the chain plate gap.
[0048] like Figure 3As shown, the chain plate body 3 is provided with sieve holes 32 arranged in an array along the length of the movable plate 6. A collection box 33 is provided at the end of the frame 1. The sieve holes 32 are used to further circulate the water. After the water flows through the sieve holes 32, it will continue to flow downward into the collection box 33. At the same time, iron filings embedded in the sieve holes 32 will fall into the collection box 33 due to the scraping of the movable plate 6 and the impact of the adjustment plate 7, and then be collected.
[0049] like Figure 3 、 4 As shown in Figures 8 and 8, a guide plate 11 is installed above the chain plate body 3, and the inner wall of the guide plate 11 is a curved surface.
[0050] The function of the guide plate 11 is to guide the working iron chips to the chain plate body 3. The curved surface is more likely to form a gathering, avoiding splashing and causing the iron chips to scatter, thereby improving the centralized cleaning efficiency of the iron chips.
[0051] like Figure 9 As shown, a CNC lathe includes any one of the above-mentioned chain plate type chip conveyors, including a machine tool body 8, a cutting tool seat 81 and a guard plate 82. The machine tool body 8 is located at the front end of the frame 1, and the cutting tool seat 81 is installed on the machine tool body 8. The cutting tool seat 81 is located above the chain plate body 3, and the guard plate 82 is installed above the cutting tool seat 81. The guard plate 82 corresponds to the guide plate 11.
[0052] A guard plate 82 is added to the cutting seat 81 so that the debris generated during work is blocked by the guard plate 82 and falls into the collection box 33. It cooperates with the guide plate 11 to restrain the movement of flying iron chips, thereby ensuring that the iron chips can fall onto the chain plate, thereby improving the chain plate's effect on transporting and collecting iron chips.
[0053] When it is necessary to collect and transport the iron chips, the staff starts the motor 21, which drives the rotating shaft 23 to rotate. The sprocket 22 on the rotating shaft 23 drives the chain plate body 3 to rotate synchronously. The chain plate body 3 is a cluster composed of multiple chain plates, and the chain plates will gradually guide and discharge the chips. At this time, the cutting tool seat 81 is started, and the chips generated by the processing are blocked by the guard plate 82 and the guide plate 11 at the same time. At this time, the chips will fall towards the chain plate body 3, thereby completing the collection effect.
[0054] During the circulation of the chain plate body 3, the long plate 541 on the back of the chain plate body 3 will contact the end of the protrusion 53 on the fixed plate 51, thereby driving the push block to compress the return spring 52, thereby driving the movable plate 6 above the protrusion 53 to scrape the gap between the chain plate bodies 3. After the long plate 541 passes over the protrusion 53, the short plate 542 does not contact the protrusion 53, and then the protrusion 53 is reset under the action of the return spring 52, thereby driving the movable plate 6 to move repeatedly, thereby improving the cleaning effect of the movable plate 6 on the chain plate. Synchronously, after the long plate 541 passes over the protrusion 53, it contacts the limit block 57 again, and the Keen people drive the limit block 57 to move up and down, so that the limit block 57 squeezes the compression spring 56, and the limit block 57 squeezes the adjusting plate 7, and the adjusting plate 7 hits the side wall of the chain plate body 3, forming a cleaning effect, thereby improving the cleaning efficiency of the chain plate chip conveyor.
[0055] The above shows and describes the basic principles and beneficial effects of the present invention. At the same time, the present invention is not limited to the above embodiments. Without departing from the effects and scope of the present invention, the present invention may have various changes and improvements.
