Description

Technical Field

[0001] This application relates to the field of deburring technology for volute shells, and in particular to a deburring workstation for volute shells. Background Technology

[0002] A volute is a shell component with a spiral flow channel, resembling a volute in shape, with a continuous spiral curved channel inside. This unique structural design allows it to effectively guide and uniformly accelerate fluid, thereby efficiently converting the fluid's kinetic energy into pressure energy. It is widely used in fluid power equipment such as centrifugal pumps and turbochargers.

[0003] During the casting and machining of volute casings, burrs inevitably form on the edges, corners, corners, and holes of the workpiece due to process limitations and machining accuracy errors. These burrs not only affect the machining and assembly accuracy of the volute casing but also reduce the performance and reliability of the equipment. For example, burrs may obstruct fluid flow, increase energy loss, or even detach during equipment operation, causing internal blockages or damage.

[0004] Currently, before leaving the factory, turbine housings generally need to be sanded to remove burrs. Traditionally, sanding involves workers visually inspecting or touching the burrs to determine their location, then using sandpaper to sand the housing. However, when sanding large quantities of turbine housings, workers are prone to fatigue and missing areas, resulting in poor sanding quality. Furthermore, during deburring, burr debris easily scatters in the deburring area, affecting its cleanliness and potentially scratching the power cables, increasing equipment maintenance costs and safety risks.

[0014] Optionally, multiple guide plates are vertically arranged parallel to each other above the conveyor belt, and two adjacent guide plates form a diversion channel.

[0015] In summary, this application includes at least one of the following beneficial technical effects: 1. This volute deburring workstation utilizes automated equipment, such as a feeding conveyor, a discharging conveyor, a robotic arm, and deburring devices working in tandem. The feeding conveyor quickly and accurately transports the volute shells to be processed to the robotic arm's gripping position, while the discharging conveyor promptly transports the deburred volute shells to the next workstation. The first and second robotic arms have clearly defined roles, each responsible for transferring the volute shells between different deburring devices, avoiding time waste and operational errors caused by manual handling. Furthermore, the first and second deburring devices can perform two deburring processes on the volute shells. This multi-stage processing method effectively ensures the quality of deburring, reduces product quality problems caused by burr residue, and thus improves production efficiency and product quality stability. 2. The design of the debris handling component is ingenious. The debris collection unit effectively collects burr debris, preventing it from scattering in the work environment and reducing environmental pollution. Furthermore, a weighing unit monitors the weight of the burr debris in the collection tank in real time. When the set value is reached, the push plate power unit drives the push plate to push the debris into the extrusion tube. This quantitative collection and transfer method makes debris handling more organized. In the extrusion tube, the extruder compresses the burr debris into a columnar shape, facilitating subsequent conveying and processing. This centralized collection, extrusion molding, and orderly discharge method for burr debris not only reduces potential safety hazards such as cuts to workers caused by burr debris but also facilitates unified recycling or processing of the debris, meeting environmental protection and safe production requirements. 3. The movable unit (casters) at the bottom of the mounting frame allows the position of the entire debris collection assembly to be adjusted according to actual production needs. For example, if deburring of different models of volute housings is required, or if the relative position of the deburring device and other equipment such as robotic arms needs to be adjusted to optimize the workflow, this can be achieved by moving the mounting frame. Furthermore, the blocking unit of the extrusion tube uses easily tearable cardboard, a design that ensures smooth discharge of extruded burrs and debris while also facilitating replacement and maintenance. Moreover, the insertion-fitting of the extrusion tube with the positioning slot of the support column, and the insertion-fitting of the extrusion column with the guide hole and extrusion tube, all contribute to greater flexibility and convenience in equipment assembly and maintenance, enabling rapid adaptation to different production tasks and equipment adjustment requirements.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figures 1-12 This application will be described in further detail.

[0030] This application discloses a deburring workstation for volute casings.

[0031] Reference Figure 1 A deburring workstation for a volute includes a feeding conveyor 1, a robotic arm, a deburring device, and a discharging conveyor 12. The feeding conveyor 1 and the discharging conveyor 12 are both fixedly installed at predetermined positions on the ground, and are parallel to each other. A manual inspection table 61 is placed between the feeding conveyor 1 and the discharging conveyor 12.

[0032] The robotic arm includes an identical first robotic arm 2 and a second robotic arm 3. The first robotic arm 2 is fixedly installed near the end of the feeding conveyor 1, and the second robotic arm 3 is fixedly installed near the beginning of the unloading conveyor 12. A transfer platform 6 is placed between the first robotic arm 2 and the second robotic arm 3. The deburring device includes an identical first deburring device 4 and a second deburring device 5. The first deburring device 4 is fixedly installed on the ground near the first robotic arm 2, and the second deburring device 5 is fixedly installed on the ground near the second robotic arm 3.

[0033] When it is necessary to remove burrs from the volute casing, the worker places the volute casing to be deburred on the feeding conveyor 1. The feeding conveyor 1 transports the volute casing to a position close to the first robotic arm 2. The first robotic arm 2 picks up the volute casing and moves it close to the first deburring device 4. The first deburring device 4 grinds the burrs on the volute casing and collects the removed burrs. After the first robotic arm 2 carries the volute casing and finishes grinding at the first deburring device 4, it places the volute casing on the transfer platform 6. The second robotic arm 3 picks up the volute casing from the transfer platform 6 and moves it to the second deburring device 5 for further burr removal. Then, the deburred volute casing is placed on the unloading conveyor 12, which transports the deburred volute casing to the next workstation.

[0034] At the manual inspection station 61, staff members use their palms to touch the volute shell to confirm whether the burrs have been completely removed. If the burrs on the volute shell are not completely removed, the volute shell is placed back on the feeding conveyor 1 to remove the burrs again. If a large number of volute shells are not completely deburred, the first robotic arm 2, the second robotic arm 3, the first deburring device 4, and the second deburring device 5 are specifically inspected or calibrated according to the location of the remaining burrs, so as to ensure the quality of volute shell deburring.

[0035] Reference Figure 1 and Figure 2In order to ensure the accuracy of the position of the volute shell during feeding, in this embodiment of the application, the feeding conveyor 1 is a chain plate conveyor. The chain plate conveyor has a positioning seat 11 fixedly installed on the chain plate. The positioning seat 11 is provided with multiple positioning rods 111. The positioning rods 111 and the connecting holes of the connecting plate on the volute shell are inserted and matched. The positioning rods 111 further improve the posture stability of the volute shell placed on the positioning seat 11, thereby facilitating the accurate grasping of the first robot arm 2.

[0036] The transfer platform 6 is also fixed with a positioning seat 11 to place the vortex shell after it has been polished by the first deburring device 4. By placing the vortex shell in a specific position, it is easy for the second robotic arm 3 to grasp it accurately.

[0037] The first deburring device 4 includes a grinding component 41 and a chip processing component 42. The grinding component 41 grinds the burrs on the volute, and the chip processing component 42 collects the chips from the grinding of the volute and compresses the collected chips into a columnar shape for subsequent conveying and processing.

[0038] Reference Figure 1 and Figure 3 The grinding device includes a grinding frame 411 and a deburring machine 412. The grinding frame 411 is fixedly installed in a predetermined position, and the deburring machine 412 is fixedly installed on the grinding frame 411. The first robotic arm 2 grasps the volute shell and approaches the grinding end of the deburring machine 412 to perform deburring.

[0039] Reference Figure 3 , Figure 4 and Figure 7 The debris collection assembly includes a debris collection section 7, a debris extrusion section 8, and a debris discharge section 9. The debris collection section 7 is located directly below the burr grinder 412. Both the debris collection section 7 and the debris discharge section 9 are located inside the debris collection section 7. The debris collection section 7 collects burr debris and conveys the collected burr debris to the debris extrusion section 8 for extrusion molding. The debris extrusion section 8 discharges the extruded debris for easy transfer.

[0040] Reference Figure 4 and Figure 5 The debris collection unit 7 includes a mounting frame 71, a collection funnel 72, and a conveyor 73. Multiple movable units 711 are fixedly mounted on the bottom of the mounting frame 71, distributed at the four corners of the bottom of the mounting frame 71. In this embodiment, the movable units 711 are casters, which support the mounting frame 71 and allow it to move, facilitating adjustments to the position of the mounting frame 71.

[0041] Multiple protective plates 712 are mounted on the mounting frame 71, and the protective plates 712 are distributed circumferentially along the vertical center line of the mounting frame 71. A collecting funnel 72 is fixedly mounted on the mounting frame 71, and the vertical center line of the collecting funnel 72 coincides with the vertical center line of the mounting frame 71. The cross-sectional area of ​​the collecting funnel 72 gradually decreases from top to bottom, and the sidewall of the collecting funnel 72 forms a guiding surface for burr debris.

[0042] Reference Figure 4 , Figure 5 and Figure 6 The conveying component 73 includes a placement seat 731, a push plate 732, and a push plate power unit 733. The placement seat 731 is approximately a horizontally placed triangular prism. A weighing unit 7311 is fixedly connected to the bottom of the placement seat 731. In this embodiment, the weighing unit 7311 is a pressure sensor, which is fixedly mounted on the mounting bracket 71. The weighing unit 7311 supports the placement seat 731. The relatively large contact area between the placement seat 731 and the weighing unit 7311 improves the placement stability of the placement seat 731 and the uniformity of the force on the weighing unit 7311.

[0043] A collection groove 7312, which is arc-shaped, is formed along the length of the placement base 731. The collection groove 7312 is located directly below the collection funnel 72, and its size is larger than the outlet size of the collection funnel 72. This allows all burrs and debris from the collection funnel 72 to slide into the collection groove 7312 without leakage. After being guided by the collection funnel 72, the burrs and debris are discharged from the outlet of the collection funnel 72 and fall into the collection groove 7312 under their own gravity. The weighing unit 7311 detects the total weight of the burrs and debris inside the collection groove 7312 of the placement base 731 in real time. Since the weight of the placement base 731 remains constant, the weight of the burrs and debris in the collection groove 7312 can be measured. To reduce the weight of the placement base 731, it is hollow.

[0044] A push plate 732 is disposed inside the collection tank 7312. The push plate 732 is a circular plate, and its axial direction is parallel to the length direction of the collection tank 7312. A certain gap is left between the push plate 732 and the inner wall of the collection tank 7312, thereby reducing the interference of the push plate 732 on the weighing unit 7311 without affecting the push plate 732's ability to push burrs and debris inside the collection tank 7312. At the same time, in order to facilitate the push plate 732 to clean the burrs and debris inside the collection tank 7312 as thoroughly as possible, a brush can also be installed on the push plate 732 near the inner wall of the collection tank 7312.

[0045] The push plate power unit 733 is fixedly mounted on the mounting bracket 71. In this embodiment, the push plate power unit 733 is a slide cylinder. The push plate 732 is fixedly connected to the slide of the slide cylinder via a connecting rod. The push plate power unit 733 and the weighing unit 7311 are electrically connected via a cable. After the weighing unit 7311 detects that the weight of burrs and debris inside the collection tank 7312 exceeds a set value, after the grinding of the volute currently being ground is completed, the push plate power unit 733 drives the push plate 732 to move inside the collection tank 7312, reducing the possibility that debris inside the collection tank 7312 will be discharged away from the discharge hole 7313 and scattered in the working area.

[0046] The weighing unit 7311 detects that the weight of burrs and debris inside the collection trough 7312 exceeds the set value. This is mainly to make the amount of burrs and debris in subsequent extrusion approximately consistent, and since the weight of burrs that need to be removed from a single volute is relatively small, it has little impact on the weight of the overall extruded burrs and debris.

[0047] The bottom of the inner wall of the collection tank 7312, away from the push plate power unit 733, is provided with a discharge hole 7313. The discharge hole 7313 penetrates the bottom of the placement seat 731. The push plate 732 pushes the burrs and debris to the discharge hole 7313 and then discharges them. A baffle 7314 is vertically installed at the end of the placement seat 731 away from the push plate power unit 733. A baffle 7315 is provided on the baffle 7314. The baffle 7315 includes a pair of side plates. The length direction of the side plates is consistent with the length direction of the placement seat 731. The two side plates correspond one-to-one with the two sides of the collection tank 7312 along its length direction. The side plates are located above the side wall of the collection tank 7312.

[0048] A collection area is formed between the baffle 7314, the push plate 732, the side plate, and the wall of the collection tank 7312. When the burr debris falls into the collection area under its own gravity, the baffle 7314, the push plate 732, the side plate, and the wall of the collection tank 7312 block the burr debris, reducing the possibility of the burr debris being splashed out of the collection area again.

[0049] Reference Figure 7 , Figure 8 and Figure 9 The debris extrusion section 8 includes a base plate, a rotating disk 81, a support member 82, and an extrusion member 83. The base plate is horizontally fixed on the mounting frame 71, and the rotating disk 81 is horizontally positioned above the base plate. A rotary cylinder is installed between the rotating disk 81 and the base plate, and the rotary cylinder drives the rotating disk 81 to rotate around the axis of the rotating disk 81.

[0050] The side of the rotating disk 81 is provided with multiple placement slots circumferentially along the axis of the rotating disk 81. Each placement slot is provided with a fixing seat 811. The fixing seat 811 is arranged in a semi-circular shape. The bottom of the outer wall of the fixing seat 811 is provided with a fixing groove 812. The vertical groove wall of the fixing groove 812 fits with the groove wall of the placement slot, and the horizontal groove wall of the fixing groove 812 fits with the top of the rotating disk 81, thereby completing the positioning. The fixing seat 811 and the rotating disk 81 are fixedly connected by bolts, which improves the convenience of connection.

[0051] The fixed base 811 is arranged in an arc shape on the side away from the axis of the rotating disk 81. A vertically arranged extrusion tube 813 is fixedly connected to the arc surface. The outer wall of the extrusion tube 813 fits into the arc surface. The stability of the extrusion tube 813 is improved by increasing the contact area between the extrusion tube 813 and the arc surface.

[0052] The top of the extrusion tube 813 is provided with an opening, and the bottom of the extrusion tube 813 is closed by a blocking unit. The blocking unit has an easy-to-tear effect. The blocking unit is bonded to the tube wall of the extrusion tube 813. In this embodiment, the blocking unit is a paper shell.

[0053] Reference Figure 6 , Figure 7 and Figure 8 The extrusion tube 813 is located below the placement seat 731, and the diameter of the extrusion tube 813 is slightly larger than the diagonal dimension of the cross-section of the discharge hole 7313. When the burrs and debris are discharged from the collection tank 7312, the rotating cylinder drives the rotating disk 81 to rotate. The rotating disk 81 drives the empty extrusion tube 813 to move below the placement seat 731 and directly below the discharge hole 7313.

[0054] In order to facilitate the discharge of debris from the discharge hole 7313 into the extrusion tube 813, the inner diameter of the bottom of the discharge hole 7313 gradually decreases from top to bottom, forming a funnel shape, and the inner diameter of the bottom of the discharge hole 7313 is smaller than the inner diameter of the bottom of the discharge hole 7313.

[0055] Once the burrs and debris inside the collection tank 7312 reach the predetermined weight, the push plate 732 pushes the burrs and debris on the collection tank 7312 to the discharge hole 7313, and into the extrusion tube 813. Since the push plate 732 only discharges the burrs and debris into the extrusion tube 813 after the debris inside the collection tank 7312 reaches the predetermined weight, the weight of the burrs and debris inside the extrusion tube 813 is basically the same. Therefore, the volume of the burrs and debris extruded is basically the same, which facilitates the extrusion of burrs and debris and the collection of the extruded burrs and debris.

[0056] Reference Figure 7 and Figure 10The support member 82 is fixedly installed on the base plate. The support member 82 includes a support plate 821 and a support column 822. The support plate 821 is horizontally positioned above the base plate. Multiple guide rods 823 are vertically fixedly installed at the bottom of the support plate 821. The guide rods 823 penetrate the base plate and slide in cooperation with the base plate. In this embodiment, there are two guide rods 823.

[0057] The support plate 821 moves vertically by pushing the power unit 824. In this embodiment, the power unit 824 is a cylinder. The cylinder is fixedly installed at the bottom of the base plate. The cylinder push rod passes through the base plate and is fixedly connected to the bottom of the support plate 821. The support plate 821 moves vertically by extending and retracting the cylinder.

[0058] A pair of limiting seats 825 are provided at the top of the base plate near the support plate 821. The support plate 821 is a long plate, and the ends of the limiting seats 825 correspond one-to-one with the ends of the support plate 821. The limiting seats 825 are arranged in an inverted L shape, and a limiting rod 826 is vertically inserted through the top of the limiting seat 825. Two limiting nuts 827 are threaded onto the limiting rod 826, and the two limiting nuts 827 clamp the limiting seat 825. The relative position of the limiting rod 826 and the limiting nuts 827 is adjusted by adjusting their relative positions. The bottom of the limiting rod 826 and the base plate form the movable range of the support plate 821. The highest vertical position of the support plate 821 is limited by the contact between the bottom of the limiting rod 826 and the top of the support plate 821.

[0059] Support columns 822 are fixedly installed on the top of support plate 821. Multiple support columns 822 are provided along the length of support plate 821. In this embodiment, there are two support columns 822. The top of the support column 822 is provided with positioning groove 8221. The extrusion tube 813 and the positioning groove 8221 are inserted and matched.

[0060] When it is necessary to squeeze the burrs and debris inside the extrusion tube 813, the power unit 824 pushes the support plate 821 to move upward. The support plate 821 drives the support column 822 to move upward synchronously, and the positioning groove 8221 on the support column 822 fits onto the extrusion tube 813 located directly above the support column 822. The bottom of the inner wall of the positioning groove 8221 contacts the bottom of the extrusion tube 813 inside the positioning groove 8221 to support the blocking unit on the extrusion tube 813. This reduces the possibility that the blocking unit will be completely damaged during the extrusion process, which could lead to the leakage of the burrs and debris.

[0061] The extrusion component 83 includes a placement frame 831, an extrusion plate 832, and a support plate 833. The placement frame 831 includes a first column 8311, a second column 8312, a first placement plate 8313, and a second placement plate 8314. There is a pair of first columns 8311, which are vertically arranged. The two first columns 8311 correspond one-to-one with two limiting seats 825, and the two limiting seats 825 are located between the two first columns 8311.

[0062] The first placement plate 8313 is horizontally positioned above the extrusion tube 813. The first placement plate 8313 is located between the two first columns 8311. Each end of the first placement plate 8313 is integrally formed with a pair of clamping strips 83131. The pair of clamping strips 83131 clamps the adjacent first column 8311. The pair of clamping strips 83131 is provided with locking holes 83132. A bolt and nut assembly is provided at the locking holes 83132. The pair of clamping strips 83131 clamps the first column 8311 through the bolt and nut assembly, thereby fixing the first placement plate 8313 on the first column 8311.

[0063] The initial position of the first placement plate 8313 can be easily adjusted by adjusting the relative position of the clamping bar 83131 and the first column 8311. The second column 8312 is vertically fixedly installed on the top of the first placement plate 8313. There are multiple second columns 8312. In this embodiment, the second columns 8312 are distributed around the second placement plate 8314. The second placement plate 8314 is horizontally fixed on the top of the second columns 8312, and the second placement plate 8314 is supported by the multiple second columns 8312.

[0064] The extrusion plate 832 is horizontally disposed between the first placement plate 8313 and the second placement plate 8314. The extrusion plate 832 moves vertically through the extrusion power unit 8321. In this embodiment, the extrusion power unit 8321 is a cylinder. The cylinder is vertically fixed to the top of the second placement plate 8314. The cylinder push rod passes through the second placement plate 8314 and is fixedly connected to the top of the extrusion plate 832.

[0065] Multiple extrusion columns 8322 are vertically fixed at the bottom of the extrusion plate 832. Multiple extrusion columns 8322 are provided along the length of the extrusion plate 832. In this embodiment, two extrusion columns 8322 are provided. Multiple guide holes are provided on the first placement plate 8313. In this embodiment, two guide holes are provided. The two extrusion columns 8322 correspond one-to-one with the two guide holes. The extrusion columns 8322 are inserted into the corresponding guide holes. The extrusion tube 813 located directly below the extrusion column 8322 is also inserted into the extrusion tube 813.

[0066] When the extrusion tube 813 is in the extrusion position, the support plate 821 drives the support column 822 to rise, and the bottom of the inner wall of the positioning groove 8221 on the support column 822 contacts the extrusion tube 813 through the support column 822. Then, the extrusion plate 832 drives the extrusion column 8322 to move downward, pass through the guide hole, and insert into the extrusion tube 813 located directly above the support column 822, extruding the burrs and debris inside the extrusion tube 813 into a column shape.

[0067] The support plate 833 is horizontally positioned on top of the first placement plate 8313. The support plate 833 moves horizontally with the first placement plate 8313 via a support power unit 8331. The support power unit 8331 is an electric push rod, which is fixedly mounted on the first placement plate 8313. The push rod end of the electric push rod is fixedly connected to the support plate 833, and the support plate 833 moves on the first placement plate 8313 via the electric push rod.

[0068] The support plate 833 is provided with two support grooves 8332 corresponding one-to-one with the extrusion column 8322. The extrusion column 8322 and the support grooves 8332 are inserted into each other. When it is not necessary to extrude the burrs and debris inside the extrusion tube 813, the support plate 833 is moved by the support power unit 8331, so that the bottom end of the extrusion column 8322 abuts against the top of the support plate 833. This reduces the possibility that the extrusion column 8322 will move downward and interfere with the movement of the extrusion tube 813 when the air pressure inside the extrusion power unit 8321 fails. At the same time, when the extrusion column 8322 is not used, the air supply to the extrusion power unit 8321 can be stopped, so that the extrusion column 8322 and the support plate 833 are in contact, thus saving energy.

[0069] When the extrusion column 8322 needs to extrude the burrs and debris inside the extrusion tube 813, the bearing plate 833 is moved by the bearing power unit 8331 so that the bearing groove 8332 is located directly below the extrusion column 8322, so that the extrusion column 8322 can extrude the burrs and debris inside the extrusion tube 813 through the bearing groove 8332.

[0070] Reference Figure 4 , Figure 7 , Figure 11 and Figure 12 The debris discharge section 9 includes a discharge frame 91, a discharge component 92, a conveyor belt 93, and a collection box 94. The discharge frame 91 includes a top fixedly mounted on the base plate. The discharge component 92 includes a discharge plate 921 and a guide tube 922. The discharge plate 921 is horizontally mounted on the discharge frame 91 and moves vertically via a discharge power unit 923, which is an electric push rod. The electric push rod is fixedly mounted on the discharge frame 91, and its push rod is fixedly connected to the top of the discharge plate 921. A discharge column 9211 is vertically fixedly mounted on the bottom of the discharge plate 921.

[0071] The guide tube 922 is fixedly installed on the discharge frame 91, and is located between the discharge column 9211 and the extrusion tube 813. The discharge column 9211 and the guide tube 922 are inserted into each other, and the discharge column 9211 and the extrusion tube 813 are also inserted into each other. When it is necessary to discharge the extruded burrs and debris from the extrusion tube 813, the discharge column 9211 is guided by the guide tube 922 and then inserted into the extrusion tube 813 to discharge the burrs and debris inside the extrusion tube 813. During the burr and debris discharge process, the blocking unit that is attached to the bottom of the extrusion tube 813 is detached from the extrusion tube 813.

[0072] Reference Figure 4 , Figure 9 , Figure 11 and Figure 12 The conveyor belt 93 is located below the extrusion tube 813 and is driven by a motor. The starting end of the conveyor belt 93 is located directly below the discharge column 9211. The collection box 94 is located below the end of the conveyor belt 93 and is slidably fitted with the mounting frame 71 to facilitate removal of the collection box 94 for further processing of the extruded burrs and debris inside. Multiple parallel guide plates 931 are vertically arranged above the conveyor belt 93 and are fixedly mounted on the conveyor frame of the conveyor belt 93. Adjacent guide plates 931 form a diversion channel, into which the extruded burrs and debris fall. During the conveying process of the conveyor belt 93, the guide plates 931 guide the debris to ensure it is neatly conveyed into the collection box 94. To ensure the extruded burrs and debris fall correctly into the diversion channel, each extrusion tube 813 is located directly above a single diversion channel, and the outer diameter of the extrusion tube 813 is slightly smaller than the width of the diversion channel, facilitating the discharge of the extruded burrs and debris into the diversion channel.

[0073] Meanwhile, during the extrusion molding process, the burrs and debris will get stuck in the blocking unit. When the extruded burrs and debris are discharged onto the conveyor belt 93, the burrs and debris and the blocking unit fall down at the same time. The burrs and debris come into contact with the conveyor belt 93 through the blocking unit. The blocking unit blocks the burrs and debris and protects the conveyor belt 93, reducing the possibility of the burrs and debris scratching the conveyor belt 93.

[0074] The implementation principle of a volute deburring workstation according to an embodiment of this application is as follows: In the volute deburring workstation, the operator first places the volute to be deburred on the feeding conveyor 1, which transports the volute to a position close to the first robotic arm 2. The first robotic arm 2 picks up the volute and moves it to the first deburring device 4. The grinding component 41 of the first deburring device 4 grinds the volute to remove burrs, while the debris processing component 42 collects and compresses the burr debris. After grinding, the first robotic arm 2 places the volute on the transfer table 6, and the second robotic arm 3 picks up the volute from the transfer table 6 and moves it to the second deburring device 5 for further deburring. Afterward, the second robotic arm 3 places the deburred volute on the unloading conveyor 12, which transports the volute to the next workstation. At the manual inspection station 61, staff members check by touching the volute shell to confirm whether the burrs have been completely removed. If not, the volute shell is placed back onto the feeding conveyor 1 for further burr removal. If a large number of volute shells are not completely deburred, the first robotic arm 2, the second robotic arm 3, the first deburring device 4, and the second deburring device 5 are inspected or calibrated according to the location of the remaining burrs to ensure the quality of volute shell deburring.

[0075] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
