Technical Field
[0001] This invention relates to the field of valve processing technology, and in particular to a valve transmission gear cutting processing device. Background Technology
[0002] A gear is a mechanical component that transmits motion and power through continuous meshing of gears on its rim. Gears can be classified into parts such as teeth, tooth grooves, end faces, normal faces, addendum circles, root circles, base circles, and pitch circles according to their structure. Commonly used steels for manufacturing gears include tempered steel, quenched steel, carburized and quenched steel, and nitrided steel.
[0003] After gear machining is completed, further finishing processes such as chamfering and milling are required to meet assembly accuracy and usage requirements. During gear cutting, due to the characteristics of the machining process, problems such as high-speed friction, localized high temperatures, chip adhesion, and easy damage to precision surfaces are unavoidable. These problems directly affect gear machining accuracy, tooth surface quality, and machining efficiency. Cutting fluid, as a special auxiliary medium in gear cutting, effectively alleviates these machining pain points through its four core functions: cooling, lubrication, chip removal, and rust prevention, ensuring gear machining quality and continuity.
[0004] However, existing gear cutting equipment still has obvious shortcomings in practical applications: the sprayed cutting fluid and chips are easily scattered in the processing area, and traditional devices do not have a directional return structure, which easily leads to problems of residue and incomplete return, requiring manual cleaning, which is time-consuming and labor-intensive. Therefore, we propose a valve-driven gear cutting processing device. Summary of the Invention
[0005] The purpose of this invention is to provide a valve transmission gear cutting processing device that has the function of directional recovery and filtration of cutting fluid to save manpower.
[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a valve transmission gear cutting and machining device, comprising a frame, side plates symmetrically mounted on the frame, and a top plate connected to the other side of the side plates. A cutting assembly is installed between the two side plates, and an inclined guide plate is installed between the two side plates. A plurality of fixed assemblies are rotatably connected to the frame along the X-axis direction. The fixed assemblies penetrate and extend above the guide plates. A driving assembly for driving the plurality of fixed assemblies to rotate is also installed on the frame. A liquid storage tank and a separation tank are sequentially installed on the frame from top to bottom. A return flow is connected between the lower side of the guide plate and the separation tank. The flow tube and the separation box are equipped with a filter screen with a notch. A collection box is slidably connected to the separation box at the position corresponding to the notch. A debris separation component is also rotatably connected to the separation box. The debris separation component is rotatably connected to the drive component via a synchronous belt. A spray component with one end fixed to the cutting component is connected to the storage tank. A supply component is installed between the separation box and the storage tank. A push component that meshes with the debris separation component is slidably connected to the inner wall of the separation box. The rotation of the debris separation component drives the push component to slide back and forth, thereby driving the supply component to operate and circulate the clean cutting fluid filtered by the filter screen in the separation box to the storage tank.
[0007] By adopting the above technical solution, when machining valve transmission gears, the gears to be machined are first fixed one by one on each fixed component to ensure that the gears are firmly clamped and accurately positioned. After the machining is started, the cutting component can align the gears on each fixed component along the preset trajectory to carry out cutting operations such as chamfering and milling. During the cutting process, the drive component starts synchronously, driving multiple fixed components to rotate at a uniform speed and synchronously, which in turn drives the clamped gears to rotate synchronously. This works in conjunction with the cutting component to complete the uniform machining of the entire outer circumference of the gear, ensuring the gear cutting accuracy and tooth surface quality.
[0008] During the cutting operation, the spray assembly sprays cutting fluid onto the machining area to provide cooling and lubrication. After use, the cutting fluid, carrying metal chips generated during machining, is guided by the inclined guide plate and then flows back to the separation box through the return pipe. The cutting fluid entering the separation box first passes through the filter screen, which completely intercepts and removes the metal chips mixed in, thus achieving the initial separation of cutting fluid and chips.
[0009] At the same time, the drive component drives the debris separation component in the separation box to rotate synchronously via a synchronous belt. During the rotation of the debris separation component, the metal debris intercepted on the filter screen can be gradually pushed to the preset gap in the filter screen, and finally the debris falls into the collection box that is slidably connected to the corresponding gap on the separation box, realizing the centralized discharge and collection of metal debris, which is convenient for subsequent unified cleaning.
[0010] The clean cutting fluid, after being filtered by the filter screen, will naturally settle and collect at the bottom of the separator. When the debris separation component rotates, it engages with the push component that is slidably connected to the inner wall of the separator, thereby driving the push component to slide back and forth along the inner wall of the separator. The reciprocating motion of the push component can drive the supply component to start running, stably circulating and transporting the clean cutting fluid collected at the bottom of the separator to the storage tank, completing the closed-loop replenishment of cutting fluid and ensuring continuous and efficient cutting operations.
[0011] A further configuration of the present invention is as follows: the cutting assembly includes a back plate connected between two side plates, a linear guide rail mounted on the back plate, a sliding seat that slides horizontally on the linear guide rail, a cylinder mounted on the sliding seat, a connecting block that slides vertically on the sliding seat, and a milling cutter mounted on the other side of the connecting block, wherein the output end of the cylinder is connected to the connecting block.
[0012] By adopting the above technical solution, the sliding seat and the linear guide rail slide horizontally together. By sliding the sliding seat horizontally along the linear guide rail, the cylinder, connecting block and milling cutter on the sliding seat can be moved horizontally synchronously, realizing the horizontal position adjustment of the milling cutter and accurately aligning it with the gear to be processed on each fixed component. When the cylinder is started, its output end extends and retracts, which can drive the connecting block to slide vertically along the sliding seat, thereby driving the milling cutter to rise and fall vertically synchronously, realizing precise control of the milling cutter's cutting feed.
[0013] A further configuration of the present invention is as follows: the fixing assembly includes a rotating shaft rotatably connected to the frame along the X-axis direction, the rotating shaft passing through and extending above the guide plate, a lower washer and a sprocket are mounted on the outer side of the rotating shaft, an upper washer is also fitted on the outer side of the rotating shaft, and a locking cap is threaded to the top of the rotating shaft.
[0014] By adopting the above technical solution, after the gear to be processed is mounted on the rotating shaft and initially positioned by fitting with the lower shim, the upper shim is mounted on the outside of the rotating shaft so that the upper shim fits tightly against the top of the gear. Then, the locking cap is threaded onto the top of the rotating shaft. By tightening the locking cap clockwise, the locking force of the threaded connection causes the locking cap to press down on the upper shim. In turn, the upper and lower shims form a bidirectional clamping force, which firmly clamps the gear to be processed between the two, thus completing the fixation of the gear to be processed.
[0015] A further feature of the present invention is that the sprocket is located below the guide plate, the other structures are located above the guide plate, and a sealing element is provided at the position where the rotating shaft passes through the guide plate.
[0016] By adopting the above technical solution, the guide plate can prevent the first sprocket from slipping, thus avoiding the chips from getting stuck on the first sprocket during the cutting process and affecting its transmission. At the same time, the seal can prevent the cutting fluid from leaking to the bottom of the guide plate.
[0017] A further configuration of the present invention is as follows: the drive assembly includes a drive motor mounted on the frame and a reducer connected to the output shaft of the drive motor. The input end of the reducer is electrically connected to the output end of the drive motor. A synchronous pulley is mounted on the output shaft of the drive motor, and a sprocket is mounted on the output shaft of the reducer. The sprocket and multiple sprockets are connected by chain drive.
[0018] By adopting the above technical solution, the drive motor starts and drives the synchronous pulley one and the reducer on its output shaft to rotate. The power adjusted by the reducer is transmitted to the sprocket two through its output shaft. Since the sprocket two is connected to the sprocket one on multiple fixed components through chain drive, the chain can synchronously transmit the rotational power of the sprocket two to each sprocket one, so that the rotating shaft synchronously drives the clamped gear to rotate at a uniform speed, realizing uniform cutting of the entire circumference of the gear. By reducing the speed of the rotating shaft by the reducer, it can better adapt to the requirements of gear processing.
[0019] A further configuration of the present invention is as follows: the debris separation assembly includes a rotating rod rotatably connected to the separation box, a second synchronous wheel, a half gear and a cross plate mounted on the rotating rod, and bristles mounted on the bottom of the cross plate, wherein the second synchronous wheel is connected to the first synchronous wheel via a synchronous belt.
[0020] By adopting the above technical solution, when synchronous pulley one rotates, it drives the rotating rod to rotate through synchronous belt and synchronous pulley two. When the cutting fluid entering the separation box is filtered out by the filter screen, and metal debris remains on the filter screen, the rotating rod drives the brush to rotate, scraping the remaining metal debris to the notch for discharge.
[0021] A further feature of the present invention is that the return pipe extends into the separation box and is offset from the notch, with one end of the return pipe extending into the separation box located inside the synchronous belt.
[0022] By adopting the above technical solution, interference between the returning cutting fluid and the timing belt can be avoided, thus preventing the timing belt from affecting transmission.
[0023] A further configuration of the present invention is as follows: the spray assembly includes a spray head mounted on the sliding seat and a pressure pump mounted on the liquid storage tank, the inlet end of the pressure pump is connected to the liquid storage tank, and a flexible hose is connected between the outlet end of the pressure pump and the spray head.
[0024] By adopting the above technical solution, the pressure pump starts and its inlet end is connected to the storage tank. It can quickly draw clean cutting fluid that has been circulated and filtered in the storage tank and pressurize it so that it can be sprayed out through the hose and spray head. The hose has good flexibility and extensibility and can be flexibly adapted to the sliding seat. Cutting fluid can be sprayed on gears in different machining positions.
[0025] A further configuration of the present invention is as follows: the supply assembly includes a cylinder penetrating one side inner wall of the separation tank, a piston slidably mounted on the cylinder, and an inlet pipe and an outlet pipe connected to the cylinder. The piston is provided with a sealing ring, and both the inlet pipe and the outlet pipe are provided with one-way valves. The other end of the inlet pipe is connected to the separation tank, and one end of the outlet pipe is connected to the storage tank.
[0026] A further configuration of the present invention is as follows: the pushing assembly includes a loop-shaped mounting bracket that slides horizontally within the separation box, two rows of retaining teeth mounted on the inner side of the loop-shaped mounting bracket, and a connecting rod mounted on the loop-shaped mounting bracket. The other end of the connecting rod extends into the cylinder body and is hinged to the piston. The half gear alternately meshes with the two rows of retaining teeth on the loop-shaped mounting bracket.
[0027] By adopting the above technical solution, when the rotating rod rotates, it drives the externally mounted half gear to rotate synchronously. When the half gear rotates in the forward direction, it meshes with one row of teeth, causing the U-shaped mounting bracket to slide horizontally in one direction along the inner wall of the separator. When the half gear continues to rotate to the other side, it meshes with another row of teeth, causing the U-shaped mounting bracket to slide horizontally in the reverse direction. This achieves continuous reciprocating horizontal sliding of the U-shaped mounting bracket. When the U-shaped mounting bracket drives the piston to slide away from the separator via the connecting rod, the volume of the cylinder near the inlet pipe increases and the pressure decreases. Under the action of the pressure difference, the clean cutting fluid in the separator opens the one-way valve on the inlet pipe and enters the cylinder to complete the suction. At this point, the one-way valve on the outlet pipe remains closed because the pressure inside the cylinder is lower than the pressure inside the reservoir, preventing the cutting fluid in the reservoir from flowing back. When the U-shaped mounting bracket drives the piston to slide closer to the separator via the connecting rod, the volume inside the cylinder decreases and the pressure increases. The clean cutting fluid inside the cylinder pushes open the one-way valve on the outlet pipe and is transported to the reservoir through the outlet pipe to complete the drainage. At this time, the one-way valve on the inlet pipe remains closed because the pressure inside the cylinder is higher than the pressure inside the separator, preventing the cutting fluid inside the cylinder from flowing back to the separator. The piston continues to slide back and forth, thus realizing the continuous and stable delivery of cutting fluid from the separator to the reservoir, completing the closed-loop replenishment of cutting fluid.
[0028] The beneficial effects of this invention are:
[0029] 1. During the cutting process, the drive assembly starts synchronously, driving multiple fixed components to rotate at a uniform speed, which in turn drives the clamped gear to rotate synchronously. This works in conjunction with the cutting assembly to complete the uniform machining of the entire outer circumference of the gear, ensuring the gear cutting accuracy and tooth surface quality.
[0030] 2. The spray assembly sprays cutting fluid onto the machining area for cooling and lubrication. After use, the cutting fluid, carrying metal chips generated during machining, is guided by an inclined guide plate and then flows back to the separation box through a return pipe. The cutting fluid entering the separation box first passes through a filter screen, which completely intercepts and removes the metal chips mixed in. At the same time, the drive assembly drives the chip separation assembly in the separation box to rotate synchronously via a synchronous belt. During the rotation of the chip separation assembly, the metal chips intercepted on the filter screen are gradually pushed to the preset gaps on the filter screen, and finally the chips fall into the collection box at the corresponding gaps on the separation box, realizing the centralized discharge and collection of metal chips, facilitating subsequent unified cleaning, eliminating the need for manual cleaning, and saving costs.
[0031] 3. The clean cutting fluid filtered by the filter screen will naturally settle and collect at the bottom of the separator. When the debris separation component rotates, the push component, which is slidably connected to the inner wall of the separator, engages with each other, thereby driving the push component to slide back and forth along the inner wall of the separator. The reciprocating motion of the push component can drive the supply component to start running, stably circulating and transporting the clean cutting fluid collected at the bottom of the separator to the storage tank, completing the closed-loop replenishment of cutting fluid and ensuring continuous and efficient cutting operations.
[0032] 4. Through the mechanical linkage of the drive component, synchronous belt, chip separation component, push component, and supply component, as well as the linkage between the drive component and the stationary component, the three core processes of gear cutting, chip cleaning, and cutting fluid circulation and replenishment are closely connected to form a closed-loop linkage that requires no manual intervention. While the gear is cutting, the chip pushing and collection and the cutting fluid filtration and circulation are completed simultaneously. There is no need to start the cleaning and circulation mechanisms separately, which greatly improves the continuity of the processing flow and further improves the efficiency of batch processing. A single power source drives the operation of multiple components in a coordinated manner, avoiding the energy loss when multiple power sources work at the same time. It realizes the centralized and efficient use of energy and eliminates the need to frequently start and stop different power mechanisms, further reducing the overall energy consumption and conforming to the trend of energy-saving and environmentally friendly equipment design.

[0042] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0043] Example 1, as Figures 1-6As shown, a valve transmission gear cutting and machining device includes a frame 1, side plates 2 symmetrically mounted on the frame 1, and a top plate 3 connected to the other side of the side plates 2. A cutting assembly 4 is installed between the two side plates 2, and an inclined guide plate 5 is installed between the two side plates 2. Multiple fixing assemblies 6 are rotatably connected to the frame 1 along the X-axis. The fixing assemblies 6 pass through and extend above the guide plate 5. A driving assembly 7 for driving the multiple fixing assemblies 6 to rotate is also installed on the frame 1. A liquid storage tank 13 and a separation tank 8 are installed sequentially from top to bottom on the frame 1. A return pipe 16 connects the lower side of the guide plate 5 and the separation tank 8. A filter screen 9 is installed inside the separation tank 8, and the filter screen 9 has openings... There is a notch 10. A collection box 18 is slidably connected to the separation box 8 at the position corresponding to the notch 10. A chip separation component 11 is also rotatably connected to the separation box 8. The chip separation component 11 is rotatably connected to the drive component 7 via a synchronous belt 12. A spray component 14 with one end fixed to the cutting component 4 is connected to the liquid storage tank 13. A supply component 15 is installed between the separation box 8 and the liquid storage tank 13. A push component 17 that meshes with the chip separation component 11 is slidably connected to the inner wall of the separation box 8. The rotation of the chip separation component 11 drives the push component 17 to slide back and forth, thereby driving the supply component 15 to run, circulating and transporting the clean cutting fluid filtered by the filter screen 9 in the separation box 8 to the liquid storage tank 13.
[0044] Working principle: When machining valve transmission gears, the gears to be machined are first fixed one by one on each fixed component 6 to ensure that the gears are firmly clamped and accurately positioned. After the machining is started, the cutting component 4 can align with the gears on each fixed component 6 along the preset trajectory to carry out cutting operations such as chamfering and milling. During the cutting process, the drive component 7 starts synchronously, driving multiple fixed components 6 to rotate at a uniform speed and synchronously, thereby driving the clamped gears to rotate synchronously. This works in conjunction with the cutting component 4 to complete the uniform machining of the entire outer circumference of the gear, ensuring the gear cutting accuracy and tooth surface quality.
[0045] During the cutting operation, the spray assembly 14 sprays cutting fluid into the machining area to provide cooling and lubrication. After use, the cutting fluid, carrying metal chips generated during machining, is guided by the inclined guide plate 5 and then flows back to the separation box 8 through the return pipe 16. The cutting fluid entering the separation box 8 first passes through the filter screen 9, which completely intercepts and filters out the metal chips mixed in, thus achieving the initial separation of cutting fluid and chips.
[0046] At the same time, the drive component 7 drives the debris separation component 11 in the separation box 8 to rotate synchronously via the synchronous belt 12. During the rotation of the debris separation component 11, the metal debris intercepted on the filter screen 9 can be gradually pushed to the preset notch 10 of the filter screen 9, and finally the debris falls into the collection box 18 that is slidably connected to the corresponding notch 10 on the separation box 8, so as to realize the centralized discharge and collection of metal debris, which is convenient for subsequent unified cleaning.
[0047] The clean cutting fluid filtered by filter screen 9 will naturally settle and collect at the bottom of the separator 8. When the debris separation component 11 rotates, the push component 17, which is slidably connected to the inner wall of the separator 8, engages with each other, thereby driving the push component 17 to slide back and forth along the inner wall of the separator 8. The reciprocating motion of the push component 17 can drive the supply component 15 to start running, stably circulating and transporting the clean cutting fluid collected at the bottom of the separator 8 to the storage tank 13, completing the closed-loop replenishment of cutting fluid and ensuring continuous and efficient cutting operations.
[0048] In this embodiment, the cutting assembly 4 includes a back plate 41 connected between two side plates 2, a linear guide rail 42 mounted on the back plate 41, a sliding seat 43 that slides horizontally on the linear guide rail 42, a cylinder 44 mounted on the sliding seat 43, a connecting block 45 that slides vertically on the sliding seat 43, and a milling cutter 46 mounted on the other side of the connecting block 45. The output end of the cylinder 44 is connected to the connecting block 45. The sliding seat 43 slides horizontally with the linear guide rail 42. By sliding the sliding seat 43 horizontally along the linear guide rail 42, the cylinder 44, the connecting block 45, and the milling cutter 46 on the sliding seat 43 can be driven to move horizontally synchronously, thereby achieving horizontal position adjustment of the milling cutter 46 and accurately aligning it with the gears to be processed on each fixed assembly 6. When the cylinder 44 is started, its output end extends and retracts, which can drive the connecting block 45 to slide vertically along the sliding seat 43, thereby driving the milling cutter 46 to rise and fall vertically synchronously, thereby achieving precise control of the cutting feed of the milling cutter 46.
[0049] In this embodiment, the fixing component 6 includes a rotating shaft 61 rotatably connected to the frame 1 along the X-axis. The rotating shaft 61 passes through and extends above the guide plate 5. A lower washer 62 and a sprocket 65 are installed on the outer side of the rotating shaft 61. An upper washer 63 is also fitted on the outer side of the rotating shaft 61. A locking cap 64 is threaded to the top of the rotating shaft 61. After the gear to be processed is fitted onto the rotating shaft 61 and initially positioned by fitting with the lower washer 62, the upper washer 63 is fitted onto the outer side of the rotating shaft 61 so that the upper washer 63 fits tightly against the top of the gear. Then, the locking cap 64 is threaded to the top of the rotating shaft 61. By tightening the locking cap 64 clockwise, the locking force of the threaded connection causes the locking cap 64 to press down on the upper washer 63. Thus, the upper washer 63 and the lower washer 62 form a bidirectional clamping force, firmly clamping the gear to be processed between them, thus completing the fixing of the gear to be processed.
[0050] In this embodiment, the sprocket 65 is located below the guide plate 5, and other structures are located above the guide plate 5. A sealing element is provided at the position where the rotating shaft 61 passes through the guide plate 5. The guide plate 5 can prevent the sprocket 65 from slipping, thus preventing chips from getting stuck on the sprocket 65 during the cutting process and affecting its transmission. At the same time, the sealing element can prevent cutting fluid from leaking to the bottom of the guide plate 5.
[0051] In this embodiment, the drive assembly 7 includes a drive motor 71 mounted on the frame 1 and a reducer 72 connected to the output shaft of the drive motor 71. The input end of the reducer 72 is electrically connected to the output end of the drive motor 71. A synchronous pulley 73 is mounted on the output shaft of the drive motor 71, and a sprocket 74 is mounted on the output shaft of the reducer 72. The sprocket 74 and multiple sprockets 65 are connected by a chain 75. When the drive motor 71 starts, it drives the synchronous pulley 73 and the reducer 72 to rotate. The power adjusted by the reducer 72 is transmitted to the sprocket 74 through its output shaft. Since the sprocket 74 and multiple sprockets 65 on the fixed assembly 6 are connected by a chain 75, the chain 75 can synchronously transmit the rotational power of the sprocket 74 to each sprocket 65, thereby causing the rotating shaft 61 to synchronously drive the clamped gear to rotate at a uniform speed, achieving uniform cutting of the entire circumference of the gear. By reducing the speed of the rotating shaft 61 by the reducer 72, it can better adapt to the requirements of gear processing.
[0052] In this embodiment, the debris separation assembly 11 includes a rotating rod 111 rotatably connected to the separation box 8, a second synchronous wheel 112, a half gear 113, and a horizontal plate 114 mounted on the rotating rod 111, and brush bristles 115 mounted on the bottom of the horizontal plate 114. The second synchronous wheel 112 is connected to the first synchronous wheel 73 via a synchronous belt 12. When the first synchronous wheel 73 rotates, it drives the rotating rod 111 to rotate via the synchronous belt 12 and the second synchronous wheel 112. When the cutting fluid entering the separation box 8 is filtered out by the filter screen 9, and metal debris remains on the filter screen 9, the rotating rod 111 drives the brush bristles 115 to rotate, scraping the remaining metal debris to the notch 9 for discharge.
[0053] In this embodiment, the return pipe 16 extends into the separation box 8 and is offset from the notch 10. One end of the return pipe 16 extending into the separation box 8 is located inside the synchronous belt 12 to avoid interference between the returning cutting fluid and the synchronous belt 12, which would affect the transmission of the synchronous belt 12.
[0054] In this embodiment, the spray assembly 14 includes a spray head 141 mounted on the sliding seat 43 and a pressure pump 142 mounted on the liquid storage tank 13. The inlet end of the pressure pump 142 is connected to the liquid storage tank 13, and a hose 143 is connected between the outlet end of the pressure pump 142 and the spray head 141. When the pressure pump 142 is started, its inlet end is connected to the liquid storage tank 13, which can quickly draw clean cutting fluid after circulation filtration in the liquid storage tank 13 and pressurize it so that it can be sprayed out through the hose 143 and the spray head 141. The hose 143 has good flexibility and extensibility, which can be flexibly adapted to the sliding seat 43, and cutting fluid can be sprayed on gears in different machining positions.
[0055] In this embodiment, the supply assembly 15 includes a cylinder 151 penetrating one side inner wall of the separation box 8, a piston 152 slidably mounted on the cylinder 151, and an inlet pipe 153 and an outlet pipe 154 connected to the cylinder 151. The piston 152 is provided with a sealing ring. Both the inlet pipe 153 and the outlet pipe 154 are provided with one-way valves 155. The other end of the inlet pipe 153 is connected to the separation box 8, and one end of the outlet pipe 154 is connected to the storage tank 13. The pushing assembly 17 includes a U-shaped mounting bracket 171 that slides horizontally in the separation box 8, two rows of retaining teeth 172 mounted on the inner side of the U-shaped mounting bracket 171, and a connecting rod 173 mounted on the U-shaped mounting bracket 171. The other end of the connecting rod 173 extends into the cylinder 151 and is hinged to the piston 152. The half gear 113 alternately meshes with the two rows of retaining teeth 172 on the U-shaped mounting bracket 171.
[0056] When the rotating rod 111 rotates, it drives the externally mounted half gear 113 to rotate synchronously. When the half gear 113 rotates in the forward direction, it meshes with one row of teeth 172, causing the U-shaped mounting bracket 171 to slide horizontally in one direction along the inner wall of the separator 8. When the half gear 113 continues to rotate to the other side, it meshes with another row of teeth 172, causing the U-shaped mounting bracket 171 to slide horizontally in the reverse direction, thus realizing the continuous reciprocating horizontal sliding of the U-shaped mounting bracket 171. When the U-shaped mounting bracket 171 drives the piston 152 to slide away from the separator 8 through the connecting rod 173, the volume of the cylinder 151 near the inlet pipe 153 increases and the pressure decreases. Under the action of the pressure difference, the clean cutting fluid in the separator 8 pushes open the one-way valve 155 on the inlet pipe 153 and enters the cylinder 151 to complete the liquid intake. At this time, the liquid is discharged. The one-way valve 155 on pipe 154 remains closed because the pressure inside cylinder 151 is lower than the pressure inside reservoir 13, preventing the cutting fluid in reservoir 13 from flowing back. When the U-shaped mounting bracket 171 drives piston 152 to slide closer to separator 8 via connecting rod 173, the volume inside cylinder 151 decreases and the pressure increases. The clean cutting fluid in cylinder 151 pushes open the one-way valve 155 on outlet pipe 154 and is transported to reservoir 13 through outlet pipe 154 to complete the drainage. At this time, the one-way valve 155 on inlet pipe 153 remains closed because the pressure inside cylinder is higher than the pressure inside separator 8, preventing the cutting fluid inside cylinder from flowing back to separator 8. The piston 152 continues to slide back and forth, thus realizing the continuous and stable delivery of cutting fluid from separator 8 to reservoir 13, completing the closed-loop replenishment of cutting fluid.
[0057] Example 2: Please refer to Figure 1 , 3 In addition to embodiment 1, the inner wall of the separation box 8 is equipped with a splash guard 19 through which the rotating rod 111 passes. The rotating rod 111 is not in contact with or rotatably connected to the splash guard 19. The return pipe 16 extends into the interior of the separation box 8, passes through the splash guard 19, and is located above the filter screen 9. This prevents the cutting fluid from splashing and affecting the meshing of the half gear 113 and the U-shaped mounting bracket 171 when the rotating rod 111 drives the brush bristles 115 on the horizontal plate 114 to clean metal debris.
[0058] Example 3: Please refer to Figure 1 and 7 Based on Embodiments 1 and 2, a baffle 20 is installed on the front side of the frame 1. The baffle 20 can prevent external dust and impurities from entering the interior of the frame 1, avoid the transmission between the chain 75 and the sprocket 2 and sprocket 65, and ensure that the fixed gear can rotate stably for cutting.
[0059] The control method of this invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.
