[0022] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of the present application.

[0023] The present application provides a kind of automatic turning equipment for valve production as shown in Figures 1 to 10 The present application provides a kind of automatic turning equipment for valve production as shown in

[0024] The base 1 is fixedly installed on the flat ground, and the upper surface thereof is a planar structure. A first sliding rail 6 and a second sliding rail 7 are arranged in parallel along the longitudinal direction at the central region of the upper portion of the base 1. The arrangement of the first sliding rail 6 and the second sliding rail 7 facilitates the movement adjustment of the upper cutter 10, thereby improving the turning precision and turning effect of the valve core 3. The first sliding rail 6 and the second sliding rail 7 are parallel to each other and extend through the length direction of the entire base 1. The cutter 10 is movably installed at a fixed distance between the first sliding rail 6 and the second sliding rail 7. The cutter 10 continuously works and turns the valve core 3. Specifically, during the turning process of the valve core 3, the cutter 10 rotates while the valve core 3 does not rotate. At the same time, the cutter 10 can adjust its height and movement distance along the first sliding rail 6 according to the actual machining needs, which facilitates the machining and turning of the required hole in the valve core 3.

[0025] The upper part of the first sliding rail 6 is provided with a supporting rod 2 in parallel with the length direction of the device, and the supporting rod 2 is coaxial with the first sliding rail 6. The cutter 10 is installed between the first sliding rail 6 and the supporting rod 2 through a sliding mechanism. The supporting rod 2 supports and limits the movement of the cutter 10, further improving the stability and efficiency of the movement of the cutter 10. The lower end of the cutter 10 is in sliding fit with the first sliding rail 6, and the upper end is in limiting and guiding relationship with the supporting rod 2, so that the cutter 10 can move stably in the length direction of the base 1. The first sliding rail 6 is relatively close to the central axis on the base 1.

[0026] The clamping assembly 9 is in vertical relationship with the supporting rod 2 in the horizontal direction. The clamping assembly 9 stably clamps the valve core 3 and can drive the valve core 3 to rotate. The lower end of the clamping assembly 9 is fixedly connected to the upper left end face of the base 1 and is located on the left end extension line of the first sliding rail 6 and the second sliding rail 7, thereby providing a positioning reference for clamping the workpiece. After the valve core 3 is clamped at the center of the clamping assembly 9, the axis of the valve core 3 is in parallel relationship with the supporting rod 2 and the first sliding rail 6. Therefore, the cutter 10 moves above the first sliding rail 6 and accurately turns the valve core 3.

[0027] The supporting assembly 4 comprises an outer shell 403 which is slidingly connected to the upper side of the second sliding rail 7 and provides support for the entire supporting assembly 4. The movement of the outer shell 403 drives the movement of the entire supporting assembly 4. The bottom of the outer shell 403 is provided with a sliding groove 8 which is slidingly connected to the second sliding rail 7. The sliding groove 8 facilitates the stable sliding of the outer shell 403 above the second sliding rail 7. An arc-shaped ring 404 is fixedly connected to the upper side of the outer shell 403 and corresponds to the valve core 3, thereby further improving the accuracy and comprehensiveness of the support and cooling of the valve core 3. Support blocks 402 are symmetrically arranged on the inner side of the arc-shaped ring 404. Arc-shaped clamping members 401 are symmetrically fixedly arranged on the top of the support blocks 402 and provide support for the valve core 3. The support blocks 402 not only support and fix the arc-shaped clamping members 401, but also allow the cooling liquid flowing inside to further enter the arc-shaped clamping members 401 and cool the valve core 3.

[0028] The support assembly 4 further comprises: a sliding block 407 closely attached to the arc-shaped holder 401 and slidingly connected to the inner side of the arc-shaped holder 401; the sliding block 407 moves inside the arc-shaped holder 401 and adjusts the clamping force on the valve core 3, thereby ensuring the force balance of the valve core 3 during turning, an adjusting part 406 having one end fixedly provided with symmetric side walls of the sliding block 407 and the other end fixedly connected to the side wall of the arc-shaped holder 401, the adjusting part 406 being made of a heat-sensitive material and radially expanding when heated; when the turning width of the valve core 3 continuously increases, the temperature value at the adjusting part 406 continuously increases, and the adjusting part 406 continuously expands; an elastic part 408 having two ends respectively connected to the inner top end of the sliding block 407 and the inner side of the arc-shaped holder 401; the elastic part 408 is elastic and elastically supports the sliding block 407; a pressing block 405 fixedly provided at the top end of the sliding block 407, the pressing block 405 being elastic and used for elastically clamping the valve core 3, so as to further improve the clamping effect on the valve core 3; and a distance detector 11 fixedly connected to the inner wall of the sliding block 407 and used for detecting the distance value between the arc-shaped holder 401, so as to obtain the moving distance value of the sliding block 407 and further obtain the turning feed amount, thereby ensuring the turning precision.

[0029] The spraying assembly 5 comprises: a water storage cavity 502 located in the hollow area of the shell 403 and in a closed cavity structure; cooling liquid flows in the water storage cavity 502, and the liquid inlet end of the water storage cavity 502 is connected in communication with a cooling liquid tank through a pump body; a first arc-shaped cavity 501 directly connected in communication with the water storage cavity 502, the first arc-shaped cavity 501 extending along the inner periphery of the arc-shaped ring 404 and distributed around the outer periphery of the valve core 3 and maintaining a concentric position relationship with the valve core 3; the cooling liquid in the water storage cavity 502 continuously flows to the inside of the first arc-shaped cavity 501; a channel 505 penetrating through the inside of the support block 402 and centrally arranged; the cooling liquid in the first arc-shaped cavity 501 enters the inside of the channel 505; a second arc-shaped cavity 503 located in the inner space of the arc-shaped holder 401 and symmetrically distributed along the outer periphery of the valve core 3, the second arc-shaped cavity 503 being connected in communication with the first arc-shaped cavity 501 through the channel 505; the cooling liquid in the channel 505 enters the inside of the plurality of second arc-shaped cavities 503; a water outlet 504 located on the inner side of the sliding block 407 and uniformly distributed and surrounding the circumference of the valve core 3, the water outlet 504 being obliquely arranged and directly facing the valve core 3, so that the water outlet 504 can be in close correspondence with the outer surface of the valve core 3 in position, and the cooling liquid in the second arc-shaped cavity 503 is high-speed discharged through the plurality of water outlets 504 and realizes cooling and cooling of the valve core 3 and flow impurity removal.

[0030] When the adjusting part 406 is heated and expanded, the sliding block 407 is driven to move synchronously. The sliding block 407 is tightly attached to the inner side of the arc-shaped clamping part 401 and is located at the radial outer side of the valve core 3. The cooling liquid in the second arc-shaped cavity 503 cannot flow out through the gap between the sliding block 407 and the arc-shaped clamping part 401, but can only continuously enter the sliding block 407 and finally flow out at high speed through the water outlet 504. The pressing block 405 is located closest to the valve core 3 and is in contact with the outer surface of the valve core 3. The two are coaxially distributed. The arrangement of the pressing block 405 further improves the elastic pressing effect on the valve core 3. The elastic part 408 is arranged between the inner top end of the sliding block 407 and the arc-shaped clamping part 401 and extends in the radial direction. The axis of the elastic part 408 is perpendicular to the central axis of the valve core 3 and serves as a limiting part. When the volume of the adjusting part 406 decreases, the sliding block 407 is driven to move reversely under the elastic force of the elastic part 408.

[0031] In use, the device is fixedly installed on a flat ground through the base 1. The support rod 2 at the upper part of the base 1 and the first sliding rail 6 cooperate to provide guidance and support for the movement of the cutter 10. The valve core 3 to be processed is placed in the clamping assembly 9, which provides the main clamping force and circumferential positioning. The support assembly 4 is slidably connected to the second sliding rail 7 on the base 1 through the sliding groove 8 at the bottom of the outer shell 403, so that the support assembly 4 can move in the axial direction of the valve core 3. The support assembly 4 is accurately slid to the overhanging section of the valve core 3 that needs to be supported. Then the pump body is started and the cooling liquid in the water storage cavity 502 continuously enters the second arc-shaped cavity 503 through the first arc-shaped cavity 501 and the channel 505. The pressure of the cooling liquid in the second arc-shaped cavity 503 continuously increases and drives the sliding block 407 to move towards the valve core 3. The sliding block 407 drives the pressing block 405 to elastically press the outer surface of the valve core 3. In combination with the elastic connection of the adjusting part 406 and the elastic part 408 to the sliding block 407, a uniform and elastic basic support ring is formed, which prevents the valve core from being deformed in the initial state and further improves the shock absorption effect of the cutter 10 on the valve core 3 during the subsequent turning process. The valve core 3 is prevented from being damaged by long-time collision and extrusion with the sliding block 407 during the continuous turning process. During the movement of the sliding block 407, the distance detector 11 is driven to move synchronously. The distance value detected by the distance detector 11 continuously increases and reaches the preset distance value, which indicates that the sliding block 407 drives the pressing block 405 to reach the appropriate position and elastically press and fix the valve core 3, thereby further improving the accuracy and efficiency of clamping the valve core 3.

[0032] Simultaneously, the clamping assembly 9 drives the valve core 3 to rotate, and the valve core 3 rotates continuously inside the support assembly 4. The outer surface of the valve core 3 is continuously extruded by the plurality of pressing blocks 405. If the outer surface of the valve core 3 is smooth and has the same diameter, the distance value detected by the plurality of distance detectors 11 will not change. If there is a protrusion at a position of the outer surface of the valve core 3, the clamping assembly 9 drives the protrusion to continuously rotate and be elastically extruded by the pressing block 405 during the rotation of the valve core 3. The pressing block 405 synchronously drives the sliding block 407 to move reversely, and the distance value detected by the distance detector 11 decreases and is less than the set distance preset value. Therefore, the valve core 3 needs to be removed and reprocessed for subsequent turning. By means of the process, the valve core 3 can be pre-detected, and the subsequent turning accuracy is effectively improved.

[0033] Simultaneously, the sliding block 407 drives the plurality of water outlets 504 to move and slide out of the arc-shaped clamping piece 401. The cooling liquid in the second arc-shaped cavity 503 continuously flows out through the water outlet 504 located outside the arc-shaped clamping piece 401, so as to realize accurate cooling and impurity removal of the turning position of the valve core 3, and avoid that the temperature is too high during the turning of the valve core 3 and affects the strength of the valve core 3.

[0034] When the lathe tool 10 starts processing and moves horizontally to the area of the valve core 3 above a certain group of support assemblies 4, the cutting force of the area is the largest, the temperature rises sharply, and the valve core 3 has a bending deformation trend. This deformation trend is directly converted into an additional pressure on the pressing block 405 directly below. This process triggers the coordinated response of the support assembly 4 and the spraying assembly 5. The cutting heat is conducted to the adjusting part 406 in the area, so that the adjusting part 406 is heated and expanded. The expansion of the adjusting part 406 drives the sliding block 407 to produce an additional outward displacement. The pressure is transmitted to the sliding block 407 of the group, forcing the sliding block 407 to overcome the increased tension of the elastic part 408. This displacement makes the support force of the pressing block 405 on the valve core 3 increase sharply, forming a strong local support point, effectively resisting the deformation caused by the cutting force, ensuring the machining accuracy of the point, and preventing the valve body 3 from deforming and breaking.

[0035] When the turning feed amount gradually deepens, the area cutting force gradually increases, and the temperature gradually rises, causing the adjusting part 406 to continuously expand due to heat, and the expansion of the adjusting part 406 continuously pushes the sliding block 407 to move outward, the movement of the sliding block 407 causes more water outlets 504 inside it to move outward along the arc-shaped clamping part 401 and be exposed, and the cooling liquid from the second arc-shaped cavity 503 is immediately sprayed to the surface of the valve core 3 and the area of the tool 10 through these exposed water outlets 504 with a larger flow and a wider coverage, further improving the cooling effect of the valve core 3 surface, avoiding the risk of temperature rise and thermal deformation of the valve core 3 itself, and the increased cooling liquid further improves the flow and impurity removal effect of the tool 10 position, avoiding the accumulation of debris generated during the turning of the valve core 3 at the tool 10 and affecting subsequent turning, effectively achieving precise cooling and chip flushing.

[0036] Since the valve core 3 is mostly cylindrical, during the turning of the tool 10 on the valve core 3, the thickness value of the position on both sides of the valve core 3 is less than the center position, so the heat expansion amount of the adjusting part 406 on both sides of the valve core 3 increases and is greater than the center position, the adjusting part 406 drives the sliding block 407 to move closer to the valve core 3 position, the distance value detected by the distance detector 11 increases, and the distance value is the distance preset value set for this position each time. The distance preset value can be obtained through multiple experiments, the sliding block 407 drives the pressing block 405 to increase the support force on both sides of the valve core 3, and the sliding block 407 moves to increase the outward movement of the water outlet 504, so the cooling liquid amount of the water outlet 504 on both sides increases, and the valve core 3 effectively realizes point support and precise cooling, meets the special turning requirements of the valve core 3, has stronger adaptability, and has higher precision.

[0037] At the same time, when the tool 10 finishes turning at this position and moves to the next position, the temperature of the adjusting part 406 decreases, and the adjusting part 406 cools and shrinks, then under the action of the pulling force of the elastic part 408, the sliding block 407 is pulled back to the initial position, the sliding block 407 drives the pressing block 405 to move in the opposite direction, the pressing force of the pressing block 405 on the valve core 3 decreases, effectively avoiding the problem of long-term elastic pressing of the pressing block 405 on the valve core 3 and causing structural loss and deformation, and when the sliding block 407 moves, it synchronously drives multiple water outlets 504 to move in the opposite direction, the second arc-shaped cavity 503 blocks more water outlets 504, and the amount of cooling liquid discharged from the water outlet 504 decreases, avoiding the problem of continuous discharge of cooling liquid and causing waste.

[0038] If the feed amount of the cutter 10 increases, the heat generated in the turning process of the cutter 10 and the valve core 3 increases, the moving amount of the slider 407 driven by the adjusting part 406 to the end close to the valve core 3 increases and is greater than the set moving difference value, and the distance value detected by the distance detector 11 is greater than the distance preset value set at this position, so the valve core 3 is prone to structural loss at this feed amount, and thus it is necessary to control the cutter 10 to reduce the feed amount to ensure the continuous and stable feed turning of the cutter 10 on the valve core 3.

[0039] The grouping support assembly 4 resets and is ready to respond to the next machining cycle, and the above process is repeatedly performed to perform multi-stage reciprocating turning on the valve core 3, thereby improving the turning accuracy of the valve core 3. During the movement of the cutter 10, the slider 407 reciprocally moves under the driving of the adjusting part 406, the elastic pressing force of the valve core 3 by the pressing block 405 at the end of the slider 407 changes and increases, the strength of the machining of the valve core 3 is improved, the bending deformation or even the fracture of the side wall of the valve core 3 caused by different turning forces during the machining is avoided, and the plurality of water outlets 504 are moved synchronously under the movement of the slider 407. The amount of cooling liquid discharged from the second arc-shaped cavity 503 inside along the water outlet 504 changes constantly, further realizing the pulse flushing effect on the outer surface of the valve core 3. On the basis of ensuring that the temperature value at the turning position of the valve core 3 meets the requirements, the pulse flushing effect on the debris generated during the turning of the valve core 3 is further improved, and the debris is prevented from hindering the subsequent machining of the valve core 3.

[0040] Due to the material problem of the valve core 3 itself, the machining position of the valve core 3 suddenly breaks during the turning of the cutter 10, the extrusion force of the cutter 10 on the valve core 3 decreases and the heat generated decreases, the volume of the adjusting part 406 decreases and drives the slider 407 to move away from the end of the valve core 3, the distance value detected by the distance detector 11 decreases and is much smaller than the distance preset value set at this feed amount, so the valve core 3 does not need to be machined, the cutter 10 and the pump body stop working, the cooling liquid is no longer introduced into the second arc-shaped cavity 503, the slider 407 is reversely moved under the elastic force of the elastic part 408 to return to the original position, the pressing block 405 is reversely moved under the driving of the slider 407 and no longer elastically presses the valve core 3, the valve core 3 is taken out along the clamping assembly 9, a new valve core 3 is replaced, and the above process is repeated for turning.

[0041] After the valve core 3 is completely turned, the cutter 10 stops working, the cooling liquid is no longer introduced into the spraying assembly 5, the support assembly 4 is removed, and the valve core 3 can be taken out from the clamping assembly 9.
