Abstract

This utility model relates to a multi-angle gate cutting and displacement fixture for valve castings. The fixture includes a drive box and a chuck. Two clamping plates are provided on the outer end face of the chuck, allowing them to move closer or further apart. A clamping sensor is installed on the chuck. The two clamping plates are held on the outer end faces of two first connecting flanges on both sides. A cutting position identification device is located directly above the clamping plates. The drive box drives the chuck to rotate, positioning the first or second connecting segment directly below the cutting position identification device. The cutting position identification device photographs and identifies the first or second connecting segment, analyzes the image, and generates a cutting path information, which is then sent to the cutting equipment.

This avoids repeated positioning, saves time and effort, and reduces labor costs.

Description

Technical Field

[0001] This utility model relates to the field of valve processing technology, and in particular to a multi-angle gate cutting and displacement fixture for valve castings. Background Technology

[0002] The gating and riser are the "excess" parts that inevitably occur in the metal casting process. After the metal casting process is completed, the gating and riser are the first parts to be removed.

[0003] In casting production, the removal of risers and gating gates is a labor-intensive process with a low degree of automation.

[0004] After the valve body is cast, it needs to be cut to remove the gating gate after sand removal. Currently, manual cutting with an oxy-acetylene flame is commonly used. This process has problems such as harsh environment, high strength requirements, low efficiency, poor quality, and high cost. Environmental, health, safety, and labor issues are particularly prominent, seriously affecting and restricting the development of the valve industry. Specific problems are as follows:

[0005] (1) Dust and exhaust gas risk: Oxy-acetylene flame cutting generates a large amount of dust and exhaust gas containing harmful substances, which poses a huge risk of pollution to the workshop and even the surrounding environment if directly emitted.

[0006] (2) Occupational health hazards: Dust, exhaust gas, strong light, etc. pose significant occupational disease risks;

[0007] (3) Personal safety hazards: storage and fire prevention of acetylene and oxygen, manual high temperature, molten slag splash, irregular shape and overweight, etc., pose potential dangers to the personal safety of workers;

[0008] (4) Quality cost efficiency: Experienced manual flame cutting results in poor cross-sectional quality, requiring secondary machining by turning / milling to remove excess material and meet appearance requirements, which increases processing time and equipment and labor costs.

[0009] In addition, flame cutting is a type of thermal processing, which may cause changes in the metallographic structure of the valve body, affecting its lifespan and quality.

[0010] Therefore, the need to automate the cutting of casting gatings and risers is becoming increasingly apparent. The more complex the structure of a valve casting, the more segments its gatings and risers are divided into. When using automatic cutting equipment to cut valve castings, after cutting one segment of the gatings and risers, it is necessary to flip it over to cut another segment of the gatings and risers. Without a corresponding automatic flipping device, manual flipping and repositioning is time-consuming and laborious. Summary of the Invention

[0011] To address the aforementioned problems, the present invention aims to provide a multi-angle gate cutting and displacement fixture for valve castings. This fixture can automatically clamp the valve castings and flip them over, thereby enabling multi-angle cutting of the gates and risers. It saves time and effort, reduces labor costs, and provides high clamping strength, ensuring that the valve castings do not move during the cutting process.

[0012] To achieve the above objectives, the present invention adopts the following technical solution:

[0014] The valve casting includes a valve body and a gating system formed on the valve body. The valve body is a three-way valve, including a first circular tube and a second circular tube formed perpendicularly to the middle of the first circular tube. The first circular tube has a first connecting flange at both ends, and the second circular tube has a second connecting flange at its outer end. The gating system includes a gating block, a first runner section, and a second runner section. The first runner section includes a horizontal section located at the lower end of the gating block and parallel to the first circular tube. The two ends of the horizontal section have first connecting sections that are perpendicular to the horizontal section and connected to the first connecting flange. The horizontal section is arranged perpendicular to the axis of the second circular tube. The second runner section includes an inclined section extending from the side wall of the gating block to the second circular tube. The end of the inclined section has a second connecting section that connects to the second connecting flange. The second connecting section is arranged parallel to the axis of the first circular tube.

[0015] The chuck is equipped with a clamping sensor to sense the valve casting; two clamping plates are held on the outer end faces of the first connecting flanges on both sides, with the first connecting section and the second connecting section exposed at the outer ends of the clamping plates; a cutting part identification device is set directly above the clamping plates, and the drive box drives the chuck to rotate so that the first connecting section or the second connecting section is directly below the cutting part identification device; the cutting part identification device takes a picture of the first connecting section or the second connecting section, identifies it, analyzes it, generates a cutting path information, and sends it to the cutting equipment.

[0016] Preferably, the clamping plate is L-shaped, including a vertical plate fixed on the chuck and a horizontal plate clamping the outer end face of the first connecting flange. The two ends of the first circular tube are formed with pipe openings, and the horizontal plate is provided with positioning blocks adapted to be inserted into the pipe openings.

[0017] Preferably, the first connecting flange is provided with a plurality of connecting holes radially, and the cross plate is provided with at least one positioning rod that is partially inserted into the connecting holes.

[0018] Preferably, the positioning block and positioning rod are configured in a frustum shape on the side facing the valve casting.

[0019] Preferably, the outer side of the chuck is provided with two opposing mounting slots, and a displacement block that can move back and forth along the diameter direction of the chuck is provided in the mounting slot, and the vertical plate is fixed on the displacement block.

[0020] Preferably, the outer end face of the displacement block protrudes beyond the outer end face of the chuck, and multiple segments of locking strips are protruding from the outer end face of the displacement block and arranged along the diameter direction of the chuck. The back side of the vertical plate is provided with a locking groove that cooperates with the multiple segments of locking strips.

[0021] Preferably, the card strip and its two sides are provided with fixing holes so that multiple rows of fixing hole groups are formed on the outer end face of the displacement block, and a row of assembly hole groups is provided on the vertical plate so that they can be connected to the multiple rows of fixing hole groups respectively.

[0022] Preferably, the cutting part identification device includes an industrial camera, which is vertically arranged above the fixture and is suitable for taking pictures of the first connecting segment or the second connecting segment before cutting, identifying the edges of the first connecting segment and the first connecting flange, and the second connecting segment and the second connecting flange, and analyzing and generating cutting path information to be sent to the cutting equipment; the industrial camera is mounted on a horizontal bar, the horizontal bar is mounted on the upper end of a support rod, and the lower end of the support rod is mounted on a support platform.

[0023] The present invention adopts the above technical solution and has the following beneficial effects:

[0024] ① The fixture includes a drive box and a chuck. Two clamping plates are set on the outer end face of the chuck. After the clamping sensor on the chuck senses the valve casting, it drives the displacement block to move, so that the two clamping plates automatically clamp the valve casting. Through the rotatable chuck and clamping plate design, the valve casting can be stably clamped and the gate connection sections (first connection section and second connection section) to be cut can be exposed. The cutting part recognition device (industrial camera) automatically identifies the part to be cut and intelligently generates a precise cutting path, which significantly improves the cutting accuracy and efficiency. The drive box drives the chuck to rotate, so that the gate connection sections in different directions arrive at the cutting position in sequence, realizing multi-angle cutting in one clamping, avoiding repeated positioning.

[0025] ② The clamping plate is equipped with positioning blocks and positioning rods that cooperate with the first circular tube body and the first connecting flange of the valve casting, respectively, which greatly improves the clamping strength of the clamping plate on the valve casting, making the valve casting more stable during the cutting process and improving the cutting accuracy.

[0026] ③ The fixed position of the clamping plate on the moving block can be changed along the diameter direction of the chuck, which can be adapted to clamp valve castings of more sizes and has a wide range of applications. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more, unless otherwise expressly defined.

[0035] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0037] like Figures 1-5 The valve casting multi-angle gate cutting and displacement fixture shown includes a drive box 11 set on a support platform 10, and a chuck 12 rotatably set on the drive box 11. The outer end face of the chuck 12 is provided with two clamping plates 13 that can be relatively close to or far apart.

[0038] The valve casting 100 includes a valve body and a gating and riser formed on the valve body. The valve body is a three-way valve, including a first circular tube 1 and a second circular tube 2 formed at one end perpendicularly to the middle of the first circular tube 1. The first circular tube 1 has a first connecting flange 3 at both ends, and the second circular tube 2 has a second connecting flange 4 at its outer end. The first connecting flange 3 and the second connecting flange 4 are on the same horizontal plane. The gating and riser includes a gating block 5, a first flow channel section, and a second flow channel section. The first flow channel section includes a horizontal section 6 located at the lower end of the gating block 5 and parallel to the first circular tube 1. The two ends of the horizontal section 6 have first connecting sections 7 formed perpendicular to the horizontal section 6 and connected to the first connecting flange 3. The horizontal section 6 is arranged perpendicularly to the second circular tube 2. The second flow channel section includes an inclined section 8 extending from the side wall of the gating block 5 to the second circular tube 2. The end of the inclined section 8 is provided with a second connecting section 9 connected to the second connecting flange 4. The second connecting section 9 is arranged parallel to the first circular tube 1.

[0039] The chuck 12 is equipped with a clamping sensor for sensing the valve casting 100; two clamping plates 13 are clamped on the outer end faces of the first connecting flanges 3 on both sides, with the first connecting section 7 and the second connecting section 9 exposed at the outer ends of the clamping plates 13; a cutting part identification device is set directly above the clamping plates 13, and the drive box 11 drives the chuck 12 to rotate so that the first connecting section 7 or the second connecting section 9 is directly below the cutting part identification device; the cutting part identification device takes a picture of the first connecting section 7 or the second connecting section 9, identifies it, analyzes it, generates a cutting path information, and sends it to the cutting equipment.

[0040] In the above technical solution, the rotatable chuck and clamping plate design can stably clamp the valve casting and expose the gate connection sections (first connection section and second connection section) to be cut. A cutting location recognition device (such as an industrial camera) automatically identifies the parts to be cut and intelligently generates a precise cutting path, significantly improving cutting accuracy and efficiency. The drive box drives the chuck to rotate, causing the gate connection sections in different directions to sequentially reach the cutting position, achieving multi-angle cutting in a single clamping operation and avoiding repeated positioning.

[0041] In addition, after the cutting is completed, the industrial camera takes pictures of the valve casting to identify the cutting quality and stores the inspection results. Then the drive box flips the workpiece to enter the next section of the gate cutting or inspection cycle, realizing closed-loop control of the process and online quality monitoring, improving the overall processing automation level and yield rate, thus realizing automatic flipping of the valve casting gate, multi-angle cutting and quality inspection cycle.

[0042] like Figure 4 and Figure 5 As shown, the clamping plate 13 is L-shaped, including a vertical plate 14 fixed to the chuck 12 and a horizontal plate 15 clamping the outer end face of the first connecting flange 3. The first circular tube 1 has openings 16 at both ends, and the horizontal plate 15 is provided with positioning blocks 17 adapted to fit into the openings 16. In this technical solution, the positioning blocks are precisely inserted into the valve body openings, achieving precise radial positioning of the valve casting on the fixture, ensuring accurate workpiece center position, and reducing positional errors in subsequent cutting. The opening positioning combined with flange end face clamping effectively prevents the workpiece from rotating or shifting during cutting, ensuring cutting stability, and thus providing high-precision, stable, and anti-rotation positioning clamping.

[0043] Furthermore, the first connecting flange 3 is provided with a plurality of connecting holes 18 radially, and the cross plate 15 is provided with at least one positioning rod 19 partially inserted into the connecting holes 18. In this technical solution, the positioning rod partially inserts into the flange connecting hole, providing additional circumferential positioning, effectively preventing minor rotation of the workpiece that may occur under the action of cutting force, and forming a multi-reference constraint together with the positioning block, significantly improving the rigidity and stability of the workpiece in the fixture, ensuring a smoother and more precise cutting process, and further enhancing the axial and circumferential positioning reliability.

[0044] Furthermore, the positioning block 17 and the positioning rod 19 are configured in a frustum shape on the side facing the valve casting. In this technical solution, the frustum-shaped positioning block and the end of the positioning rod have a guiding function, which can guide the workpiece to fall into the correct position quickly and smoothly during the clamping process, reducing the requirements for the operator's clamping accuracy, speeding up the clamping process, and improving production efficiency.

[0045] Furthermore, the chuck 12 has two opposing mounting slots on its outer side, and a displacement block 21 that can move back and forth along the diameter of the chuck 12 is provided in the mounting slot. The vertical plate 14 is fixed to the displacement block 21. In this technical solution, the displacement block moves radially in the mounting slot, so that the distance between the two clamping plates can be adjusted, allowing the fixture to adapt to the clamping requirements of valve castings of different specifications (mainly different lengths or flange spacings), thus improving the versatility and flexibility of the fixture.

[0046] Furthermore, the outer end face of the displacement block 21 protrudes beyond the outer end face of the chuck 12. Multiple segments of locking strips 22, arranged along the diameter of the chuck 12, protrude from the outer end face of the displacement block 21. A groove 23, which mates with the multiple segments of locking strips 22, is provided on the back side of the vertical plate 14. In this technical solution, the multiple segments of locking strips protruding from the outer end of the displacement block mate with the groove on the back side of the vertical plate, enabling rapid pre-assembly of the displacement block and locking strips. This also improves the connection stability of the vertical plate (and clamping plate) on the displacement block and allows it to withstand vibrations during cutting.

[0047] Furthermore, the clamping strip 22 and its two sides are provided with fixing holes 24, forming multiple rows of fixing hole groups on the outer end face of the displacement block 21. The vertical plate 14 is provided with a row of assembly hole groups 25, which can be connected to the multiple rows of fixing hole groups respectively. In this technical solution, the design of multiple rows of fixing hole groups and a row of assembly hole groups allows the vertical plate to be connected by selecting different rows of fixing holes, providing more and more flexible clamping plate installation position selection to meet a wider range of workpiece sizes or special clamping requirements. Multiple connection points (fixing holes) ensure connection strength and improve the overall structural rigidity.

[0048] Furthermore, the cutting part identification device includes an industrial camera 26, which is vertically arranged above the fixture. It is suitable for taking pictures of the first connecting segment 7 or the second connecting segment 9 before cutting, identifying the edges of the first connecting segment 7 and the first connecting flange 3, and the second connecting segment 9 and the second connecting flange 4, and analyzing and generating cutting path information, which is then sent to the cutting equipment. The industrial camera 26 is mounted on a crossbar 27, which is mounted on the upper end of a support rod 28, and the lower end of the support rod 28 is mounted on a support platform 10. In this technical solution, the industrial camera is rigidly mounted on the support platform via the crossbar and support rod, ensuring high stability of the camera position and avoiding the influence of vibration. This ensures the clarity of the captured images and the accuracy of the identification results. The vertical arrangement of the camera, located directly above the fixture, provides an optimal, unobstructed overhead view, which is beneficial for clearly capturing the contours of the gate connecting segment and the flange edge, clarifying the functions of the industrial camera (path generation, quality inspection, and result storage), and strengthening the core capabilities of the automated closed-loop control system.

[0049] It should be noted that the industrial camera takes a picture and generates a DXF format file, which is transmitted to the CNC system of the cutting equipment via local area network communication. The CNC system of the cutting equipment reads the DXF file, parses the incoming DXF file, extracts the contour line information, automatically generates the machining code, and the cutting equipment performs the cutting.

[0050] The specific operational steps of the above scheme are as follows:

[0051] 1. After the clamping sensor on the chuck senses the valve casting, the chuck drives the displacement block to move so that the two clamping plates clamp the outer end faces of the first connecting flanges on both sides of the valve casting.

[0052] 2. The industrial camera takes a picture of the first connecting segment (the first segment to be cut), identifies and analyzes it to generate a cutting path information, and sends it to the CNC system of the cutting equipment. The cutting equipment receives the cutting path, generates a cutting program, and cuts the first connecting segment (the first segment to be cut). The industrial camera takes pictures, analyzes the cutting quality, and stores the detection results.

[0053] 3. The drive box drives the chuck to rotate 90° so that the second connecting section (the second section to be cut) is below the industrial camera. The industrial camera takes a picture of the second connecting section (the second section to be cut), identifies and analyzes it to generate a cutting path information, and sends it to the CNC system of the cutting equipment. The cutting equipment receives the cutting path, generates a cutting program, and cuts the second connecting section (the second section to be cut). The industrial camera takes pictures, analyzes the cutting quality, and stores the detection results.

[0054] 4. The drive box drives the chuck to rotate 90° so that the first connecting section (the third section to be cut) is below the industrial camera. The industrial camera takes a picture of the first connecting section (the third section to be cut), identifies and analyzes it to generate a cutting path information, and sends it to the CNC system of the cutting equipment. The cutting equipment receives the cutting path, generates a cutting program, and cuts the first connecting section (the third section to be cut). The industrial camera takes pictures, analyzes the cutting quality, and stores the detection results.

[0055] This solution constructs a core framework for automated flipping, inspection, and cutting, solving the problems of high-precision, stable, and rapid workpiece positioning and clamping, addressing the versatility and flexibility of the fixture (size adaptation, position adjustment), ensuring the stability and functionality of the vision recognition system, and achieving the overall effect of efficient, high-precision, automated, multi-angle cutting and online quality monitoring of valve casting gates.
