Description

Technical Field

[0001] This invention belongs to the technical field of integrated turning, grinding and drilling equipment, specifically, it relates to an integrated turning, grinding and drilling processing equipment for expansion valve seats. Background Technology

[0002] The expansion valve seat is a fixed base that forms a throttling channel inside the thermostatic expansion valve and electronic expansion valve. It works with the valve needle to form a throttling pair. The expansion valve seat turning, grinding and drilling integrated processing equipment is a special CNC composite machine tool developed for air conditioning and automotive refrigeration electronic expansion valves and thermostatic expansion valve seats. Under the premise of one clamping, it integrates multiple processing functions such as turning, grinding and drilling, and directly processes the valve seat blank into a finished product. It belongs to precision composite special machine.

[0003] Existing expansion valve seat turning, grinding, and drilling integrated machines utilize a pneumatic chuck to fix the expansion valve seat blank. The spindle then drives the workpiece to rotate, and the turning tool feeds linearly to complete the turning of the valve seat's outer diameter, end face, and center bottom hole. Subsequently, the turret switches to the drilling power head, the spindle locks and indexes, and the circumferential mounting hole is drilled. Finally, an independent grinder feeds, using a high-speed grinding wheel to precisely grind the valve seat's center throttling hole and sealing cone surface, completing the integrated machining of the expansion valve seat. However, the turning, drilling, and grinding processes generate a large amount of metal dust and chips. These dust and chips easily accumulate in the guide rails, turret, grinding unit, and workpiece clamping area, accelerating component wear and potentially intruding into electrical components, causing circuit faults. Furthermore, the accumulation of high-temperature grinding debris poses a fire safety hazard, and frequent shutdowns for cleaning reduce the equipment's continuous processing efficiency.

[0004] To address the aforementioned issues, existing technologies employ a box-shaped component installed inside the turning, grinding, and drilling machine. Airflow is then used to blow the generated metal dust and cutting fragments into the box-shaped component, ensuring the cleanliness of the machine's interior. However, the metal dust and cutting fragments collected in this simple manner mix with impurities such as grinding wheel particles. Consequently, during subsequent recycling of the cutting fragments, it is necessary to separate the fragments from the metal dust and grinding wheel particles, resulting in low resource recycling efficiency.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0019] Reference Figure 1 and Figure 2 As shown, this embodiment discloses an integrated machining equipment for expansion valve seats, comprising: an integrated machining machine 1, which is equipped with a pneumatic chuck 2, a cutting tool 3, a grinder 4, and a turret 5. The pneumatic chuck 2 is used to pneumatically hold the expansion valve seat blank, the cutting tool 3 is used for turning the outer circle, end face, and center bottom hole of the valve seat, the grinder 4 uses a grinding wheel to perform precision grinding on the center throttling hole and sealing cone surface of the valve seat, and the turret 5 can switch the drilling power head to complete the drilling of the circumferential mounting hole; a cleaning component 6, which is set on the integrated machining machine 1. After collecting metal dust and chips with air blowing and air absorption, it can quickly separate the metal dust, impurities, and chips by rolling and splashing for classified storage, thereby improving cleaning and recycling efficiency; and a vibrating component 7, which is set on the cleaning component 6. It can make the mixed metal dust and chips float briefly through vibration.

[0020] Reference Figure 2 , Figure 3 and Figure 4As shown, this embodiment discloses a cleaning component 6 comprising: a collection box 61, which is fixedly connected to the integrated turning, grinding, and drilling machine 1, and a second filter plate 617 fixedly connected inside the collection box 61, wherein the second filter plate 617 divides the collection box 61 into a double-layer structure, and the lower layer of the second filter plate 617 is a storage chamber 621; a guide plate 62, which is fixedly connected to the collection box 61, and a first filter plate 611 is fixedly connected to the guide plate 62, wherein the cross-section of the guide plate 62 is Z-shaped; a collection cylinder 67, which is fixedly connected to the guide plate 62, wherein the inner wall of the collection cylinder 67 is connected to the inner wall of the storage chamber 621, and the collection cylinder 67 encloses the first filter plate 611; and a second material pipe 6. 10. The second material pipe 610 is fixedly connected to the collection cylinder 67. A pump 69 is installed on the second material pipe 610, with one end of the second material pipe 610 placed inside the collection cylinder 67. A wind hood 63 is fixedly connected to the material collection box 61 via a rod. A blower 65 is fixedly connected to the material collection box 61, with the output end of the blower 65 connected to the wind hood 63 via a first air pipe 64. By setting up the cleaning component 6, airflow can be used to blow metal dust and shavings generated during processing off the device and collect, store, and separate them for filtration. This allows for centralized storage of metal dust and impurities, while shavings are stored separately, facilitating subsequent rapid cleaning of metal dust and impurities and recutting. The recycling of metal dust and chips improves the processing efficiency. During operation, the blower 65 is first started, supplying gas into the hood 63 through the first air pipe 64. The gas is blown out of the hood 63, dislodging residual metal dust and chips from the pneumatic chuck 2 or generated during processing. The dislodged metal dust and chips then fall onto the guide plate 62. Due to the slope of the guide plate 62 surface, the metal dust and chips roll along its surface, passing through the first filter plate 611 for initial filtration. Some of the metal dust mixed with impurities falls into the collection cylinder 67 after being filtered by the first filter plate 611. The remaining metal dust and shavings roll down from the guide plate 62 into the collection box 61 and collide with the second filter plate 617, causing the large-volume shavings to vibrate and shake off the remaining metal dust and impurities. The metal dust and impurities shaken off the shavings fall into the storage chamber 621 through the second filter plate 617 for storage. Then, the pump 69 is started to create a negative pressure and generate suction in the second feed pipe 610. The metal dust and impurities in the collection cylinder 67 and the storage chamber 621 are drawn out through the second feed pipe 610 and discharged through the external pipeline connected to the second feed pipe 610, thereby completing the filtration, separation, classification, storage and waste discharge of metal dust, impurities and shavings.

[0021] Reference Figure 3 and Figure 4As shown, this embodiment discloses a suction cup 66 fixedly connected to the guide plate 62. The suction cup 66 is connected to the second material pipe 610 via the first material pipe 68. By setting the suction cup 66, the metal dust floating inside the turning, grinding, and drilling machine 1 can be extracted, further improving the cleaning effect and cleanliness of the metal dust inside the turning, grinding, and drilling machine 1. When the pump 69 generates suction inside the second material pipe 610, it also generates suction in the first material pipe 68, causing the suction cup 66 to use suction to suck in the metal dust that is blown up and floating by the airflow of the hood 63. The dust is then transported by the first material pipe 68 to the second material pipe 610 to mix with other materials. Metal dust and impurities are discharged together, achieving the cleaning of floating dust. Multiple protrusions 612 are fixed on the first filter plate 611. The multiple protrusions 612 are evenly arranged. By setting the protrusions 612, when metal dust and shavings roll on the first filter plate 611, the surface of the first filter plate 611 becomes uneven under the force of the multiple protrusions 612, which temporarily blocks the metal dust and shavings. During the rolling process, they bounce and collide with the first filter plate 611, shaking off the attached and mixed metal dust and impurities, further improving the filtration effect of the first filter plate 611 on metal dust.

[0022] Reference Figure 5 As shown, this embodiment discloses that the cleaning component 6 further includes: a winding rod 625, which is fixedly installed on the collection box 61 by a second motor 624, wherein the second motor 624 is fixedly connected to the collection box 61, and the winding rod 625 is driven to rotate by the second motor 624; a plate 622, which is slidably installed in the storage cavity 621 by a positioning rod, and the plate 622 and the winding rod 625 are connected by a rope 626, wherein the plate 622 slides along the positioning rod as a track; and a first spring 623, which is sleeved on the rope 626, wherein the two ends of the first spring 623 are fixedly connected to the plate 622 and the inner wall of the storage cavity 621, respectively. By setting the plate 622, the metal dust and impurities accumulated inside the storage cavity 621 can be removed. The material is pushed to the area below the collection cylinder 67 for centralized extraction by the second material pipe 610, reducing excessive accumulation inside the storage chamber 621 and affecting subsequent filtration, further improving the discharge efficiency of collected metal dust and impurities. When the metal dust falls into the storage chamber 621, the second motor 624 is started, driving the winding rod 625 to rotate. The winding rod 625 rotates to wind up the rope 626, causing the rope 626 to pull the plate 622 to slide along the positioning rod as a track. The plate 622 is placed inside the storage chamber 621 and moves towards the winding rod 625, pushing the metal dust and impurities stored inside it to the position below the collection cylinder 67, where it is extracted and discharged by the second material pipe 610, completing the auxiliary discharge of metal dust and impurities inside the storage chamber 621.

[0023] Reference Figure 3As shown, this embodiment discloses that the cleaning component 6 further includes: a screw 614, which is fixedly installed on the collection box 61 via a first motor 613, wherein the first motor 613 is fixedly connected to the collection box 61, and the screw 614 is driven to rotate by the first motor 613; a pusher plate 615, which is threadedly connected to the screw 614, and is slidably installed inside the collection box 61; and a valve plate 619, which is installed on the collection box 61 via an electric telescopic rod 618, wherein the electric telescopic rod 618 drives the valve plate 619 to perform up-and-down sliding movements, and the valve plate 619 is slidably connected to the inner wall of a slot in the collection box 61. By setting the pusher plate 615, the chip fragments stored inside the collection box 61 can be concentrated and pushed towards the valve plate 619, and the pressure between the valve plate 619 and the pusher plate 615 can be used to push the chip fragments. The chips and fragments are compressed and gathered together, improving the convenience and efficiency of subsequent cleaning and recycling. During use, the first motor 613 drives the screw 614 to rotate. The rotation of the screw 614 causes the pusher plate 615 to move inside the collection box 61 towards the valve plate 619. During this movement, the pusher plate 615 concentrates the chips and fragments stored in the collection box 61 and pushes them towards the valve plate 619. The pressure between the valve plate 619 and the pusher plate 615 compresses and gathers the chips and fragments for subsequent cleaning. A protective cover 616 is fixed to the collection box 61. The protective cover 616 has a semi-circular cross-section and covers the screw 614. By setting the protective cover 616, scattered chips and fragments, as well as metal dust, can be intercepted, preventing them from contacting the screw 614 and reducing jamming and excessive wear, thus affecting its service life.

[0024] Reference Figure 5 , Figure 6 and Figure 7As shown, this embodiment discloses that the cleaning component 6 further includes: a concave part 620, which is fixedly connected to the collection box 61 and communicates with the inner wall of the collection box 61, wherein the concave part 620 encloses the valve, and a round hole rod is fixedly connected inside the concave part 620; an air cylinder 627, which is fixedly connected to the round hole rod on the concave part 620, wherein the air cylinder 627 is connected to the first air pipe 64 through a second air pipe 629, and a solenoid valve is provided on the second air pipe 629; and a piston rod 628, which is slidably installed inside the air cylinder 627, wherein... The piston rod 628 consists of a piston plate and a round rod. A return spring is fitted onto the piston rod 628. The return spring is located inside the air cylinder 627 and its two ends are connected to the air cylinder 627 and the piston rod 628, respectively. A magnet plate 630 is fixedly connected to the piston rod 628. The magnet plate 630 slides within the concave part 620. By setting the magnet plate 630, compressed chips can be pulled into the concave part 620 for subsequent processing by personnel, preventing them from remaining in the collection box 61 for a long time and affecting subsequent normal collection, thus improving the continuous collection efficiency of the collection box 61. To improve processing convenience, during use, the solenoid valve is opened to deliver part of the airflow in the first air pipe 64 to the second air pipe 629, which then delivers it to the air cylinder 627. The air pressure pushes the piston rod 628 towards the valve plate 619, causing the piston rod 628 to move the magnet plate 630 towards the valve. After the chips are compressed and shaped, the electric telescopic rod 618 is activated to drive the valve plate 619, moving the valve away from the collection box 61. When the valve plate 619 is completely detached from the collection box 61... Afterwards, the concave part 620 communicates with the inner wall of the collection box 61. At this time, the magnetic plate 630 continues to be fed in under the action of air pressure and adheres to the chip fragments, so that the compressed chip fragments are magnetically attracted and fixed under the magnetic force of the magnetic plate 630. Then, the solenoid valve is closed to stop the airflow to the second air pipe 629. At this time, the piston rod 628 is pulled to reset under the extension and retraction force of the reset spring. Then, the piston rod 628 pulls the magnetic plate 630 to reset and pulls the attracted chip fragments into the concave part 620 for storage, thus completing the removal of the magnetic metal chip fragments from the collection box 61.

[0025] Reference Figure 7As shown, this embodiment discloses a magnet plate 630 with multiple cylinders 631 fixedly connected to it. Each cylinder 631 has a sliding rod 632 slidably connected inside it. Each sliding rod 632 has a spike 633 fixedly connected to it. Each sliding rod 632 is fitted with a return spring, which is placed inside each cylinder 631, with its two ends fixed to the inner wall of the cylinder 631 and the sliding rod 632, respectively. The spike 633 has several barbs. Multiple rubber rings 634 are fixedly connected to the magnet plate 630, each rubber ring 634 enclosing a spike 633. By providing the cylinders 631, when the magnet plate 630 contacts the compressed shavings, [the following is unclear and likely refers to a different embodiment of the design]. The barb 633 is inserted into the non-magnetic metal shavings, and the barbs pull the compressed shavings into the concave part 620, improving the material handling flexibility and effectiveness of the magnet plate 630. In use, when the magnet plate 630 is fed to the position where it fits with the shavings, the barb 633 is obstructed and partially enters the cylinder 631. At this time, the magnet plate 630 continues to be fed until the barb 633 is inserted into the shavings. The barbs on the barb 633 fix the shavings and pull them to move, pulling the non-magnetic metal shavings into the concave part 620 for storage, thereby achieving the material handling of non-magnetic metal shavings.

[0026] Reference Figure 8 As shown, this embodiment discloses a vibrating assembly 7 comprising: multiple striking rods 71, each of which is slidably mounted in multiple holes in a collecting cylinder 67, wherein each striking rod 71 is fitted with a second spring 72, the two ends of which are fixedly connected to the striking rod 71 and the collecting cylinder 67 respectively; a shaft 74, which is fixedly mounted on the collecting cylinder 67 by a third motor 73, wherein the third motor 73 is fixedly connected to the collecting cylinder 67 and drives the shaft 74 to rotate; and multiple arc-shaped pieces 75, which are uniformly fixedly connected to the shaft 74, wherein the positions of the multiple arc-shaped pieces 75 correspond to the positions of the multiple striking rods 71. By setting the vibrating assembly 7, the first filter plate 611 can be continuously struck to generate vibration, causing the rolling chips on the first filter plate 611 to briefly float in the air due to vibration and then fall back down to the first filter plate 611. When a filter plate 611 collides with the first filter plate, it forcefully shakes off the metal dust and impurities adhering to and mixed on the shavings, further improving the filtration effect of metal dust and impurities. In use, the third motor 73 is first started to drive the shaft 74 to rotate. The rotation of the shaft 74 drives multiple arc-shaped rods to rotate. During the rotation, multiple arc-shaped parts 75 push multiple striking rods 71 ​​to slide towards the first filter plate 611 and strike it after contacting the first filter plate 611. This causes the first filter plate 611 to vibrate and shake off the shavings on it. The shavings briefly float in the air and then fall back down to collide with the first filter plate 611, forcefully shaking off the metal dust and impurities. After the striking is completed, the second spring 72 is used to reset and continue striking, thereby assisting the first filter plate 611 in filtering the shavings and mixed metal dust and impurities.

[0027] The implementation principle of this invention is as follows: When using the integrated turning, grinding, and drilling machine 1, the pneumatic chuck 2 is used to fix the expansion valve seat blank. Then, the spindle drives the workpiece to rotate, and the turning tool 3 feeds linearly to complete the turning of the outer circle, end face, and center bottom hole of the valve seat. Subsequently, the turret 5 switches to the drilling power head, the spindle locks and indexes, and the circumferential mounting hole is drilled. Finally, the independent grinder 4 feeds and uses a high-speed grinding wheel to perform precision grinding on the center throttling hole and sealing cone surface of the valve seat, completing the integrated machining of the expansion valve seat.

[0028] In use, the blower 65 is first started to supply gas into the shroud 63 through the first air pipe 64. The gas is blown out through the shroud 63, blowing off residual metal dust and chips generated during processing from the pneumatic chuck 2. The blown-off metal dust and chips then fall onto the guide plate 62. Under the action of the slope of the guide plate 62 surface, the metal dust and chips roll along its surface. During the rolling process, they pass through the first filter plate 611, where they undergo initial filtration. After being filtered by the first filter plate 611, the mixed metal dust and impurities fall into the collection cylinder 67. Then, the remaining metal dust and shavings roll down from the guide plate 62 into the collection box 61 and collide with the second filter plate 617, causing the large shavings to vibrate and shake off the remaining metal dust and impurities. The metal dust and impurities shaken off the shavings fall through the second filter plate 617 into the storage chamber 621 for storage. Then, the second motor 624 is started, driving the winding rod 6... 25. The winding rod 625 rotates to wind up the rope 626, causing the rope 626 to pull the plate 622 to slide along the positioning rod as a track. The plate 622, placed inside the storage chamber 621, moves towards the winding rod 625, pushing the metal dust and impurities stored inside it to a position below the collection cylinder 67. Then, the pump 69 is started to create a negative pressure and generate suction in the second material pipe 610, which draws the metal dust and impurities in the collection cylinder 67 and the storage chamber 621 through the second material pipe 610. The material is extracted and discharged through the external pipeline connected to the second material pipe 610. At the same time, when the pump 69 generates suction inside the second material pipe 610, it also generates suction in the first material pipe 68. The suction bucket 66 uses the suction to draw the metal dust blown up and floating by the airflow of the hood 63 into its interior. The dust is then transported from the first material pipe 68 to the second material pipe 610 and discharged together with other metal dust and impurities. This completes the filtration, separation, classification, storage, and waste discharge of metal dust, impurities, and shavings. Simultaneously, the third motor 73 is activated to drive the shaft 74 to rotate. The rotation of the shaft 74 drives multiple arc-shaped rods to rotate. During the rotation, multiple arc-shaped parts 75 push multiple striking rods 71 ​​to slide towards the first filter plate 611 and strike it after contacting the first filter plate 611. This causes the first filter plate 611 to vibrate, which in turn shakes up the shavings on it. The shavings briefly float in the air before falling back down and colliding with the first filter plate 611, forcefully shaking off metal dust and impurities. After the striking is completed, the second spring 72 is used to reset and continue striking, thereby assisting the first filter plate 611 in filtering the shavings and the mixed metal dust and impurities.

[0029] After filtering impurities, the first motor 613 is started to drive the screw 614 to rotate. The rotation of the screw 614 causes the pusher plate 615 to move inside the collection box 61 towards the valve plate 619. During the movement, the pusher plate 615 concentrates the shavings stored in the collection box 61 and pushes them towards the valve plate 619. The pressure between the valve plate 619 and the pusher plate 615 compresses the shavings into shape. Then, the electric telescopic rod 618 is started to drive the valve plate 619 to move away from the collection box 61. When the valve plate 619 is completely detached from the collection box 61, the concave part 620 communicates with the inner wall of the collection box 61. At the same time, the solenoid valve is opened, allowing part of the airflow in the first air pipe 64 to be delivered to the second air pipe 629. Inside, the air is delivered to the air cylinder 627 via the second air pipe 629. The air pressure pushes the piston rod 628 towards the valve plate 619, causing the piston rod 628 to move the magnetic plate 630 towards the valve. At this time, the magnetic plate 630 continues to be fed in and adheres to the chip fragments under the action of air pressure, so that the compressed chip fragments are magnetically attracted and fixed under the magnetic force of the magnetic plate 630. Then, the solenoid valve is closed to stop the airflow to the second air pipe 629. At this time, the piston rod 628 is pulled back to its original position by the extension and retraction force of the return spring. Then, the piston rod 628 pulls the magnetic plate 630 back to its original position and pulls the attracted chip fragments into the concave part 620 for storage, thus completing the removal of the magnetic metal chip fragments from the collection box 61. When the magnet plate 630 is fed to the position where it fits against the chip fragment, the barb 633 is partially obstructed and enters the interior of the cylinder 631. At this time, the magnet plate 630 continues to be fed until the barb 633 is inserted into the chip fragment. The barbs on the barb 633 fix the chip fragment and pull it to move, thus pulling the non-magnetic metal chip fragment into the concave part 620 for storage, thereby achieving the material handling of the non-magnetic metal chip fragment.
