Description

Technical Field

[0001] The invention relates to the technical field of valve countersinking processing, in particular to a countersinking device for valve processing. Background Art

[0002] Countersinking equipment for valve processing is a device specially used for countersinking during valve processing. Countersinking refers to the process of processing flat-bottomed or tapered countersunk holes on the surface of the orifice by countersinking. In valve manufacturing, the application of countersinking equipment can ensure the processing accuracy and surface quality of valve parts.

[0003] During the process of countersinking the valve surface by the countersinking equipment, the drill bit will generate high temperature. At this time, it is necessary to spray cutting fluid to cool the drill bit. However, the traditional method of spraying cutting fluid often relies on manual operation or simple mechanical control, which has problems such as untimely response and inaccurate control. For example, during the processing, if the amount of cutting fluid sprayed is insufficient or the spraying time is inaccurate, it will not be able to effectively reduce the temperature of the drill bit and the workpiece, resulting in a decrease in processing quality and an increase in safety hazards. In addition, excessive cutting fluid spraying will not only cause a waste of resources, but also pollute the processing environment and increase cleaning and maintenance costs;

[0004] Secondly, in the cutting process, cutting fluid plays a vital role. It can not only effectively cool the tool and workpiece, reduce thermal deformation and tool wear caused by cutting heat, but also provide necessary lubrication to improve the smoothness and precision of the machined surface. However, as the cutting operation proceeds, various impurities such as metal chips, sand, grease, etc. will inevitably be mixed into the cutting fluid. If these impurities are not handled in time, they will seriously contaminate the cutting fluid, reduce its cooling and lubrication performance, and thus affect the processing quality and efficiency.

[0037] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] In this embodiment, Figure 1 As shown, the cutting fluid spraying control mechanism includes a connecting pipe 703, the lower end of the connecting pipe 703 passes through and is fixedly connected to the countersinking table 1, a cavity 713 is opened inside the countersinking table 1, the connecting pipe 703 and the cavity 713 are communicated, the connecting pipe 703 passes through and is fixedly connected to the support frame 2, the end of the connecting pipe 703 away from the cavity 713 is fixedly connected to the shunt pipe 701, and the end of the shunt pipe 701 away from the connecting pipe 703 is fixedly connected to the nozzle 702, through the setting of the connecting pipe 703, the cutting fluid inside the cavity 713 opened on the countersinking table 1 can be input into the shunt pipe 701, and the cutting fluid is sprayed out through the nozzle 702 to cool the countersink 6 and the valve surface.

[0040] In this embodiment, Figure 3 As shown, a ball valve 704 is fixedly connected to the connecting pipe 703, a valve stem 705 is rotatably connected to the ball valve 704, a disc 706 is fixedly connected to the upper end of the valve stem 705, a cylinder 707 is fixedly connected to the lower end face of the disc 706, and the cylinder 707 is located at the edge of the lower end face of the disc 706. When the position of the cylinder 707 changes, the disc 706 can be moved to drive the valve stem 705 to rotate on the ball valve 704, and the ball valve 704 is opened, so that the connecting pipe 703 and the shunt pipe 701 are connected, and the cutting fluid inside the connecting pipe 703 is input into the shunt pipe 701.

[0041] In this embodiment, Figure 3 As shown, a limiting frame 708 is sleeved on the outer surface of the cylinder 707, and the cylinder 707 is slidably connected in the limiting frame 708. A sliding column 709 is fixedly connected to the limiting frame 708 on the side close to the support frame 2. The sliding column 709 penetrates and is slidably connected to the support frame 2. When the limiting frame 708 moves horizontally through the sliding connection between the sliding column 709 and the support frame 2, it can push the cylinder 707 to slide inside the limiting frame 708 while moving horizontally.

[0042] In this embodiment, Figure 3 and Figure 4As shown, the side of the limit frame 708 away from the sliding column 709 is rotatably connected to a connecting plate 710, and the side of the connecting plate 710 away from the limit frame 708 is sleeved with a hollow plate 711, the connecting plate 710 is slidably connected in the hollow plate 711, and a spring 712 is fixedly connected between the connecting plate 710 and the inside of the hollow plate 711, and the side of the hollow plate 711 away from the connecting plate 710 is rotatably connected to the side wall of the mounting frame 4.

[0043] In the prior art, the traditional cutting fluid spraying method often relies on manual operation or simple mechanical control, and there are problems such as untimely response and inaccurate control. For example, during the processing, if the cutting fluid spraying amount is insufficient or the spraying time is inaccurate, it will not be able to effectively reduce the temperature of the drill bit and the workpiece, resulting in a decrease in processing quality and an increase in safety hazards. In addition, excessive cutting fluid spraying will not only cause a waste of resources, but also pollute the processing environment and increase cleaning and maintenance costs. Compared with the prior art, the cutting fluid can be automatically sprayed during the working process of the countersink 6, and the spraying can be automatically stopped after the countersink 6 is finished. This instant response and precise control make the entire processing process more efficient and smooth, which can not only adapt to different processing requirements, but also increase or decrease the amount of cutting fluid sprayed according to the countersinking time of the countersink 6 to provide better cooling and lubrication effects, reduce the temperature of the countersink 6 and the valve, and reduce thermal deformation and thermal stress caused by high temperature, thereby improving processing accuracy and surface quality. In addition, by precisely controlling the spraying amount and time, the waste of cutting fluid is reduced, and the production cost is reduced;

[0044] Secondly, by opening a cavity 713 inside the countersinking table 1 to store the cutting fluid, and connecting the connecting pipe 703 and the cavity 713 inside the countersinking table 1, it is not only convenient to recycle the cutting fluid sprayed on the surface of the countersinking table 1, thereby reducing the waste of cutting fluid and improving resource utilization, but also after the cutting fluid sprayed on the surface of the countersinking table 1 is recycled, it is possible to avoid the cutting fluid accumulating on the surface of the countersinking table 1, thereby reducing the splashing of the subsequent cutting fluid during the spraying process, improving the processing environment, and reducing the potential harm of the cutting fluid to the operator.

[0045] In other aspects, this embodiment also provides a cutting impurity collection mechanism for centralized processing of the generated impurities, such as Figure 1 , Figure 7 and Figure 8As shown, the cutting impurity centralized collection mechanism includes symmetrically arranged inclined plates 807, which are respectively fixedly connected to both sides of the fixed groove 9. The fixed groove 9 has symmetrically opened collection grooves 805 inside. The bottom of the collection grooves 805 is fixedly connected with filter plates 806, and the filter plates 806 are connected to the cavity 713. Discharge ports 804 are symmetrically opened on both sides of the countersinking table 1, and the discharge ports 804 are connected to the collection grooves 805.

[0046] In this embodiment, Figure 1 and Figure 8 As shown, a cleaning plate 802 is slidably connected in the collecting groove 805, and a reciprocating screw 801 is threadedly connected to the cleaning plate 802. Support blocks 803 are rotatably connected to the outer surfaces of the reciprocating screw 801 on both sides, and the support blocks 803 are fixedly connected to the upper end surface of the countersinking table 1. When the reciprocating screw 801 rotates on the support block 803, it is threadedly connected to the cleaning plate 802, so that the cleaning plate 802 can be driven to slide back and forth in the collecting groove 805 to clean the inside of the collecting groove 805.

[0047] In this embodiment, Figure 8 As shown, one end of the reciprocating screw rod 801 is fixedly connected to a pulley 808, and a belt 809 is sleeved between the outer surfaces of the pulley 808. The pulleys 808 are connected to each other through the belt 809. One end of one of the reciprocating screw rods 801 is fixedly connected to a driving motor. When the driving motor is turned on to drive one of the reciprocating screw rods 801 to rotate, the other reciprocating screw rod 801 can be driven to rotate synchronously through the pulley 808 and the belt 809.

[0048] In the prior art, cutting fluid plays a vital role in the cutting process. It can not only effectively cool the tool and the workpiece, reduce thermal deformation and tool wear caused by cutting heat, but also provide necessary lubrication to improve the smoothness and precision of the machined surface. However, as the cutting operation proceeds, various impurities such as metal chips, sand, grease, etc. will inevitably be mixed into the cutting fluid. If these impurities are not handled in time, they will seriously pollute the cutting fluid, reduce its cooling and lubrication performance, and further affect the processing quality and efficiency. Compared with the prior art, the cutting impurities flushed out by the cutting fluid can be collected centrally and the impurities and the cutting fluid can be separated. Not only can the impurities generated during the cutting process, such as metal chips, sand and grease, be avoided from contaminating the cutting fluid, thereby extending the service life of the cutting fluid and reducing the replacement frequency and cost, but the separated impurities are collected centrally, which can facilitate the staff to recycle and reuse some valuable metal chips in the impurities, thereby realizing the recycling of resources.

[0049] The working process and principle involved in the overall content of the above embodiment are as follows:

[0050] When the staff needs to cut a countersink on the valve surface, the staff first places the valve in the fixing groove 9 opened above the countersinking table 1, and then fixes the valve with the help of the existing fixing mechanism, and then turns on the drilling motor 5 to drive the countersink 6 to rotate. As the countersink 6 rotates, the staff can open the cylinder 3 and push the mounting frame 4 to drive the drilling motor 5 to descend, so that the countersink 6 connected to the output end of the drilling motor 5 descends close to the valve surface. When the countersink 6 descends but does not touch the valve surface, the mounting frame 4 will pull one end of the hollow plate 711 to move downward, changing the inclination angle of the hollow plate 711. As the inclination angle of the hollow plate 711 changes, the hollow plate 711 will pull the limit through the spring 712 and the connecting plate 710. The limiting frame 708 moves, and since the limiting frame 708 is connected to a sliding column 709 on the side away from the connecting plate 710, and the sliding column 709 penetrates and is slidably connected to the supporting frame 2, when the limiting frame 708 is pulled, the sliding column 709 will be pulled to slide on the supporting frame 2, so that the limiting frame 708 moves horizontally, pushing the cylinder 707 inside the limiting frame 708 to move. When the cylinder 707 moves, it will slide inside the limiting frame 708, and at the same time, it will move the disk 706 connected to the upper end of the cylinder 707, driving the valve stem 705 to rotate in the ball valve 704, opening the ball valve 704, so that the connecting pipe 703 and the shunt pipe 701 are connected. At this time, the connecting pipe 703 will open the cavity 713. The cutting fluid is input into the shunt pipe 701 and sprayed out through the nozzle 702 connected to the shunt pipe 701, so that when the countersink 6 is subsequently lowered to contact the valve surface for work, the cutting fluid can be sprayed on the countersink 6, thereby reducing the temperature of the countersink 6 and the valve, reducing the thermal deformation and thermal stress caused by high temperature, thereby improving the processing accuracy and surface quality. After the cutting fluid is sprayed out, as the mounting frame 4 and the countersink 6 continue to descend, the mounting frame 4 will pull the hollow plate 711 to slide on the outer surface of the connecting plate 710, so that the connecting plate 710 slides out from the inside of the hollow plate 711, and pulls the spring 712 connected between the connecting plate 710 and the hollow plate 711, so that the mounting frame 4 can, after opening the ball valve 704, The countersink 6 is driven to descend to process the valve surface. The hollow plate 711, the spring 712, the connecting plate 710 and the limit frame 708 are cleverly connected so that when the countersink 6 descends but does not touch the valve surface, the cutting fluid spraying mechanism can be automatically triggered. There is no need to use a separate spraying system to work. The automatic spraying system of the cutting fluid is tightly integrated with the descending process of the countersink 6, so that the cutting fluid is supplied at the right time without additional manual operation, which ensures that the cutting fluid is in place before the countersink 6 starts working, effectively reducing the temperature during the processing. The design of the ball valve 704 enables the rotation of the valve stem 705 to accurately control the flow of the cutting fluid, avoiding the waste of the cutting fluid or premature spraying.

[0051] When the countersink 6 rotates to cut the valve surface, the cutting fluid sprays, and the debris generated by the countersink 6 during the working process will be flushed away from the valve surface. The impacted debris will fall into the fixed groove 9, and slide to the upper end surface of the filter plate 806 through the inclined surface of the side wall of the inclined plate 807 connected to the two sides of the fixed groove 9. The debris is blocked by the filter plate 806 and will remain in the collection groove 805, and the cutting fluid remaining on the surface of the debris will pass through the filter plate 806 and fall into the cavity 713 opened inside the countersinking table 1, so as to avoid impurities generated during the cutting process, such as metal chips, sand particles and grease, from contaminating the cutting fluid, thereby extending the service life of the cutting fluid and reducing the replacement frequency and cost;

[0052] During the working process of the countersinking drill 6, the staff can turn on the driving motor to drive one of the reciprocating screws 801 to rotate. Since the outer surfaces of the two reciprocating screws 801 are fixedly connected with pulleys 808 on one side, and belts 809 are sleeved between the outer surfaces of the pulleys 808, when one of the reciprocating screws 801 rotates, the pulleys 808 and the belts 809 can drive the other reciprocating screw 801 to rotate synchronously. When the reciprocating screw 801 rotates, the reciprocating screw 801 and the cleaning plate 802 are threadedly connected, so that the cleaning plate 802 can move back and forth horizontally on the outer surface of the reciprocating screw 801, and the debris remaining in the collection tank 805 is moved to both sides of the filter plate 806, and discharged from the discharge port 804 opened on the side wall of the countersinking table 1, so that the staff can collect the debris in a centralized manner, recycle and reuse some valuable metal chips in the impurities, and realize the recycling of resources.

[0053] After the countersink 6 has finished cutting the valve surface, the staff opens the cylinder 3 again to drive the mounting frame 4 to rise, so that the countersink 6 is separated from the valve surface. As the mounting frame 4 rises, the hollow plate 711 connected to the side wall of the mounting frame 4 is firstly subjected to the rebound force of the spring 712, pulling the hollow plate 711 to slide to the outer surface of the connecting plate 710 again, and then pushing the connecting plate 710 to drive the limiting frame 708 to move in the reverse direction close to the supporting frame 2. When the limiting frame 708 moves in the reverse direction, the cylinder 707 and the disc 707 are used to move the limiting frame 708 in the opposite direction. 6, which will drive the valve stem 705 to rotate in the opposite direction on the ball valve 704, thereby closing the ball valve 704, disconnecting the connection between the connecting pipe 703 and the shunt pipe 701, and preventing the cutting fluid from being sprayed out through the shunt pipe 701 and the nozzle 702 again. This instant response and precise control make the entire processing process more efficient and smooth, which can not only adapt to different processing requirements, but also increase or decrease the spraying amount of the cutting fluid according to the countersinking time of the countersink drill 6 to provide better cooling and lubrication effects, reduce the waste of cutting fluid, and reduce production costs.
