Description

Technical Field

[0001] This invention relates to the field of steel casting surface processing technology, and in particular to a composite device for precision machining and surface treatment of large steel casting components. Background Technology

[0002] Large steel casting components are widely used in wind power equipment, heavy hydraulic machinery, mining equipment and other fields. These components are large in size, heavy in weight and complex in structure. After forming, multiple processes such as flash cutting, plane milling, hole system precision machining, surface shot blasting and oxide scale removal need to be completed simultaneously. This places high demands on the load-bearing capacity of processing equipment, the flexibility of workpiece position adjustment and processing accuracy.

[0003] Chinese invention patent CN119077362A discloses a large casting surface cleaning robot system and method based on 3D vision. The system generates control signals based on processing path data and sends the control signals to the rotating component, the robot, and the processing component, so that each component processes the surface defects of the casting along the processing path.

[0004] Chinese patent CN118143663B discloses a surface treatment device and method for lathe bed after casting. The cutting and grinding operations of the end of the bed blank are combined into the surface treatment device, eliminating the need to transfer the large and heavy bed blank again, saving time and effort and increasing efficiency. In this solution, the support frame in the clamping assembly can move flexibly on the long platform with the cooperation of the sliding clamping part, and always keep its side facing the end face or side of the bed blank, so as to quickly and stably achieve the clamping and fixing operation of the bed blank.

[0005] When processing large steel castings, existing machining equipment relies on multi-degree-of-freedom robotic arms to perform surface machining processes such as cutting and grinding. To achieve full-area machining of the casting, the equipment needs to have the function of relative displacement between the casting and the robotic arm, thereby expanding the machining coverage. For hidden machining areas such as the inside and even the bottom of the casting, it is also necessary to drive the casting to rotate and adjust its angle so that the surface to be machined faces the robotic arm's cutting tool.

[0006] Currently, mainstream equipment is equipped with two independent power units. One power unit drives the load-bearing worktable for linear feed, while the other independent power unit drives the worktable for rotation and tilting. The two power systems are controlled separately and have no coordinated linkage mechanism. Large cast steel components have high self-weight and large impact loads during processing. Translation and rotation movements each require the corresponding power unit to bear the entire load independently. Therefore, both power units need to be matched with high-power drive components, resulting in high equipment capacity. Moreover, the two power units cannot work together to share the load, resulting in significant power redundancy during operation and high production and operating costs.

[0007] Therefore, it is necessary to provide a composite device for precision machining and surface treatment of large steel casting components to solve the above-mentioned technical problems. Summary of the Invention

[0008] The purpose of this invention is to provide a composite device for precision machining and surface treatment of large steel casting components, so as to solve the technical problems mentioned in the background art.

[0009] Based on the above ideas, the present invention provides the following technical solution: a composite device for precision machining and surface treatment of large steel casting components, comprising:

[0010] slide rail;

[0011] The base is slidably mounted on the slide rail and can slide linearly along the extension direction of the slide rail;

[0012] The tooling table is rotatably mounted on the base;

[0013] The surface processing mechanism is provided with at least one set along the length of the slide rail, and the surface processing mechanism is used to perform precision processing on the casting placed on the tooling table;

[0014] A rotating shaft is located below the base and is rotatably connected to the base.

[0015] The driving components are provided in two sets and are located on both sides of the rotating shaft. Each driving component can move linearly relative to the rotating shaft along the length of the slide rail.

[0016] The rotating component is fixedly mounted on the rotating shaft. When the two sets of driving components move synchronously in the same direction along the slide rail, the two sets of driving components cooperate to drive the rotating component, the rotating shaft and the base as a whole to feed linearly along the slide rail. When the two sets of driving components move in opposite directions along the slide rail, the two sets of driving components drive the rotating component to drive the rotating shaft to rotate around its own axis relative to the base.

[0017] A rotating mechanism is assembled between the rotating shaft and the tooling table. The rotating mechanism is used to convert the circumferential rotational motion of the rotating shaft into the rotational angular adjustment motion of the tooling table relative to the base.

[0018] As a further aspect of the present invention: a base is slidably mounted on the slide rail, and a drive motor is fixedly mounted on the base. The drive motor is configured to drive the base to slide linearly relative to the slide rail. The drive component is connected to the base and can move synchronously with the base.

[0019] As a further aspect of the present invention: the output end of the drive motor is connected to a drive gear, and a spur rack that meshes with the drive gear is fixedly provided on one side of the slide rail.

[0020] As a further aspect of the present invention: the driving component is a sleeve, the sleeve is hinged to the base and the hinge axis is parallel to the axis of the rotating shaft, the rotating component is a rod, the rod is arranged along the diameter direction of the rotating shaft and fixedly connected to the rotating shaft, and the end of the rod away from the rotating shaft passes through the sleeve and forms a sliding pair with the sleeve.

[0021] As a further embodiment of the present invention: the rotating mechanism mainly includes a swing arm, a cantilever, a connecting rod, a sleeve, and a slide rod. The sleeve is fixedly connected to the rotating shaft and arranged along the diameter direction of the rotating shaft. The slide rod is slidably connected to the sleeve. The swing arm is fixedly connected relative to the tooling table. The cantilever is arranged parallel to the axis of the sleeve and fixedly connected to the cantilever. The connecting rod is disposed between the cantilever and the slide rod and is perpendicular to both of them. An adapter is hinged to one end of the slide rod near the connecting rod. The two ends of the connecting rod are respectively hinged to the adapter and the cantilever.

[0022] As a further embodiment of the present invention: both the adapter and the cantilever are fixed with hinge seats, the connecting rod is hinged to the hinge seats through a second pin, the second pin is arranged parallel to the sleeve axis, and the slide rod is hinged to the adapter through a first pin, the first pin and the second pin are arranged perpendicularly.

[0023] As a further aspect of the present invention: the outer circular surface of the base is provided with a clearance groove, and the swing arm passes through the clearance groove and rotates circumferentially relative to the base.

[0024] As a further embodiment of the present invention: the tooling table includes a horizontal bearing part and a support part fixedly disposed at the bottom of the bearing part and having an arc-shaped structure, the base is configured as an arc-shaped structure and located on the outer circle side of the support part, and the base and the support part are coaxially arranged.

[0025] As a further embodiment of the present invention: one end of the swing arm is fixedly connected to the support portion, and the other end of the swing arm extends away from the support portion along the diameter direction of the support portion.

[0026] As a further aspect of the present invention: the surface processing mechanism is configured as a robotic arm, and the execution end of the robotic arm is equipped with a cutting tool for processing the surface of the casting.

[0027] Compared with existing technologies, the advantages of this invention are as follows: the entire equipment relies on only two sets of drive motors to form a shared power system. When performing linear feed operations, the output power of the two drive motors is synchronously superimposed and jointly pulls the base and casting load; when performing casting rotation and angle adjustment operations, the output power of the two drive motors cooperates with each other to drive the rotating shaft to complete the rotation. Compared with the existing technology that uses two independent high-power power units to control translation and rotation separately, this invention relies on the combined force of the two drive motors to share the heavy load, eliminating the need for a separate large-specification high-power motor, effectively reducing the rated power configuration requirements of a single motor, reducing the overall installed capacity of the equipment, and lowering the equipment manufacturing cost.

[0038] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0039] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the illustrations only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0040] like Figures 1 to 8 As shown, a composite device for precision machining and surface treatment of large steel casting components includes two sets of slide rails 4 fixedly installed on the ground. The base 3 is slidably assembled above the slide rails 4, and the base 3 can slide linearly back and forth along the extension direction of the slide rails 4. A tooling table 2 is rotatably assembled inside the base 3, which is used to support the casting 13 to be processed. In the actual processing, a tooling fixture can be installed on the upper surface of the tooling table 2 to complete the positioning and clamping of the casting 13. The fixture can be a heavy-duty pressure plate bolt fixture or a pneumatic clamping fixture. These types of fixtures are existing mature tooling structures, and will not be described in detail in this invention.

[0041] At least one surface processing mechanism 1 is arranged on one side of the slide rail 4 and along its length. In this embodiment, the surface processing mechanism 1 adopts a multi-degree-of-freedom machining robot arm. The execution end of the robot arm can be detachably equipped with various processing tools such as cutting tools, grinding tools, and drilling tools. One implementation method is to configure multiple robot arms, each equipped with different functional tools, to complete the cutting, grinding, and drilling processes separately. Another implementation method is to set up only a single robot arm, equipped with an external tool magazine. The robot arm can automatically complete tool switching to adapt to the finishing and surface treatment operations of different parts of the casting 13. The robot arm is equipped with a vision inspection component, which can collect the shape data of the casting 13 and construct a three-dimensional model of the casting 13. Based on the three-dimensional model, the processing path is planned to realize high-precision automated processing of the surface of the casting 13.

[0042] The tooling table 2 includes a horizontally arranged support portion 201 and an arc-shaped support portion 202 fixed to the bottom of the support portion 201. The base 3 also adopts an arc-shaped structure and covers the outer circumference of the support portion 202. The base 3 and the support portion 202 are coaxially assembled. This structure allows the tooling table 2 to rotate relative to the base 3 about an axis parallel to the extension direction of the slide rail 4, thereby adjusting the spatial orientation of the casting 13 on the support portion 201, such as... Figure 7 As shown, this design facilitates the robotic arm to perform precision machining and surface treatment on areas such as the side walls and inner sides of the casting 13 that are difficult to machine from a conventional perspective. Both the bearing portion 201 and the support portion 202 can be designed with openwork, which facilitates machining of the bottom of the casting 13.

[0043] Existing equipment typically uses two independent power units to drive the base 3 and the tooling table 2 respectively, in order to achieve linear feeding of the base 3 along the slide rail 4 and angular adjustment of the tooling table 2 relative to the base 3. However, large steel casting components have a large self-weight and high processing load. If the two power units bear the entire load alone, they need to be matched with high-power drive components, resulting in high overall energy consumption and low energy utilization of the equipment.

[0044] To address the shortcomings of existing technologies, this invention integrates a single shared power system between the slide rail 4 and the base 3. This power system allows for the selective implementation of two actions: linear feeding of the base 3 along the slide rail 4 and rotational adjustment of the tooling table 2 relative to the base 3. The specific structure is as follows: a base 12 is slidably mounted on the slide rail 4, and a drive motor 6 is fixedly mounted on the base 12; the output end of the drive motor 6 is connected to a drive gear 601, and a spur rack 5, meshing with the drive gear 601, is fixedly laid on the side of the slide rail 4.

[0045] A vertically arranged rotating shaft 9 is provided below the base 12, and the rotating shaft 9 is rotatably assembled with the base 3. A drive mechanism 7 is assembled between the base 12 and the rotating shaft 9. The drive motor 6 drives the base 12 and the drive mechanism 7 to move relative to the rotating shaft 9 along the length of the slide rail 4 through the meshing of the drive gear 601 and the rack 5. When the two sets of drive mechanisms 7 on both sides of the rotating shaft 9 move synchronously in the same direction along the slide rail 4, the two sets of drive mechanisms 7 work together to pull the base 3 to complete linear feed along the slide rail 4; when the two sets of drive mechanisms 7 on both sides of the rotating shaft 9 move in opposite directions along the slide rail 4, the two sets of drive mechanisms 7 work together to drive the rotating shaft 9 to rotate around its own vertical axis.

[0046] A rotating mechanism 8 is provided between the rotating shaft 9 and the support part 202 of the tooling table 2. The rotating mechanism 8 can convert the circumferential rotation of the rotating shaft 9 into the rotation of the tooling table 2 relative to the base 3, thereby adjusting the spatial posture of the casting 13 on the bearing part 201, so as to facilitate the end tool of the robotic arm to carry out precision machining and surface treatment operations on various areas of the casting 13.

[0047] In summary, this invention features two symmetrically arranged drive mechanisms 7, which operate in two modes: mode one involves the two drive mechanisms 7 moving synchronously and in the same direction along the extension direction of the slide rail 4; mode two involves the two drive mechanisms 7 moving in opposite directions along the extension direction of the slide rail 4. The overall linear feed motion of the base 3 along the slide rail 4 is achieved by mode one, while the rotational angle adjustment motion of the tooling table 2 relative to the base 3 is achieved by mode two.

[0048] The entire equipment relies on only two sets of drive motors 6 to form a shared power system. When performing linear feed operations, the output power of the two drive motors 6 is synchronously superimposed and jointly pulls the load of the base 3 and the casting 13. When performing rotation and angle adjustment operations on the casting 13, the output power of the two drive motors 6 cooperates with each other to drive the rotating shaft 9 to complete the rotation. Compared with the existing technology that uses two independent high-power power units to control translation and rotation separately, this invention relies on the combined force of the two drive motors 6 to share the heavy load, eliminating the need for a separate large-specification high-power motor. This effectively reduces the rated power configuration requirements of a single motor, reduces the overall installed capacity of the equipment, and lowers the equipment manufacturing cost.

[0049] The drive mechanism 7 consists of a rotating component 701 and a drive component 702; the rotating component 701 is connected to the rotating shaft 9 and can rotate synchronously with the rotating shaft 9; the drive component 702 is fixedly assembled to the base 12 and can slide linearly along the slide rail 4 following the base 12.

[0050] Combined with appendix Figure 3The first embodiment of the present invention is shown: the driving component 702 adopts a rack and pinion structure and is fastened to the base 12; the rotating component 701 is a gear ring, which is fixedly sleeved on the outer circumference of the rotating shaft 9 and rotates synchronously with the rotating shaft 9. The transmission process of this embodiment is as follows: the drive motor 6 outputs torque to drive the drive gear 601 to rotate; relying on the meshing transmission between the drive gear 601 and the spur rack 5 on the side of the slide rail 4, the base 12 and the rack fixed thereto are driven to generate linear displacement synchronously. When the two sets of racks move synchronously and in the same direction along the extension direction of slide rail 4, the tangential forces of the racks on both sides on the gear ring cancel each other out, the gear ring is locked and does not rotate, and the racks and gear ring form a rigid traction engagement, thereby pulling the base 3 as a whole along slide rail 4 to achieve linear feed; when the two sets of racks move in opposite directions along the extension direction of slide rail 4, the racks on both sides apply the same circumferential driving force to the gear ring, driving the gear ring to drive the rotating shaft 9 to rotate clockwise or counterclockwise, the rotational motion of the rotating shaft 9 is transmitted through the rotating mechanism 8, and finally drives the tooling table 2 to complete the rotation angle adjustment relative to the base 3.

[0051] Combined with appendix Figure 5 The second embodiment of the present invention is shown: the driving component 702 adopts a sleeve structure, the sleeve is rotatably assembled with the base 12, and its rotation axis is parallel to the axis of the rotating shaft 9; the rotating component 701 is a rod structure, the rod is fixedly installed on the outer circular side wall of the rotating shaft 9, the rod passes through the inside of the sleeve and can form a sliding pair with the sleeve.

[0052] The transmission logic of this embodiment is as follows: When the two sets of bases 12 slide synchronously in the same direction along the slide rail 4, the rods on both sides are constrained by the sleeves, and the deflection trends of the two relative to the rotating shaft 9 are mutually limited and interfered with, so the rotating shaft 9 cannot rotate. The sleeves and rods form a rigid linkage, and the rotating shaft 9 and the base 3 are pulled as a whole to complete the linear feed along the slide rail 4, thereby adjusting the horizontal processing position of the casting 13 on the tooling table 2. When the two sets of bases 12 slide in opposite directions along the slide rail 4, the lateral thrust applied by the sleeves on both sides to the rods is superimposed in the same direction along the circumference of the rotating shaft 9, thereby driving the rotating shaft 9 to rotate around its own axis. The rotating shaft 9 then drives the tooling table 2 to rotate relative to the base 3 to adjust the angle through the rotating mechanism 8.

[0053] Compared to the aforementioned rack and pinion meshing transmission embodiment, this solution eliminates the gear meshing pair and relies on the sliding hinge of the sleeve and rod to transmit power. There is no backlash error caused by tooth backlash during the transmission process, resulting in higher transmission stability and motion control precision. At the same time, the overall structure has no precision gear pair, making disassembly and maintenance of parts convenient after wear, and reducing the difficulty of overall machine maintenance.

[0054] In one embodiment, the rotating mechanism 8 includes a bevel gear 22 and a bevel rack 21. The bevel gear 22 is fixedly mounted on the top of the rotating shaft 9, and the outer circumferential wall of the support 202 is fixed with a bevel rack 21 that meshes with the bevel gear 22. By relying on the meshing transmission between the bevel gear 22 and the bevel rack 21, the tooling table 2 can be driven to rotate and adjust its angle relative to the base 3. This bevel gear 22 meshing transmission scheme has a simple structure and is easy to assemble, but the overall structural load-bearing stability is insufficient. When facing the processing conditions of large steel casting components with large self-weight and strong cutting impact, the transmission defects will become more prominent.

[0055] To overcome the defects of the bevel gear 22 transmission mentioned above, the present invention provides another preferred embodiment, wherein the rotating mechanism 8 is mainly composed of a swing arm 11, a cantilever 14, a connecting rod 15, a sleeve 19, and a slide rod 20. The specific assembly relationship is as follows: the sleeve 19 is arranged radially along the rotating shaft 9 and is rigidly connected to the rotating shaft 9; the slide rod 20 is slidably assembled inside the sleeve 19 and can slide back and forth along the axis of the sleeve 19; the swing arm 11 is arranged radially along the support part 202 and is fixedly installed on the outer circular surface of the support part 202; the cantilever 14 is fixedly connected to the swing arm 11, and the extension direction of the cantilever 14 is parallel to the axis of the sleeve 19; the connecting rod 15 is mounted between the cantilever 14 and the slide rod 20, and the rod body of the connecting rod 15 is arranged perpendicular to the axis of the sleeve 19.

[0056] Combined with appendix Figure 4 As shown, a U-shaped adapter 18 is provided at one end of the slide rod 20 near the connecting rod 15, and the adapter 18 is rotatably hinged to the slide rod 20; hinge seats 16 are fixedly installed on both the adapter 18 and the cantilever 14, and the two ends of the connecting rod 15 are respectively rotatably engaged with the two hinge seats 16. The rotation axis of the connecting rod 15 relative to the hinge seat 16 is perpendicular to the rotation axis of the adapter 18 relative to the slide rod 20.

[0057] In this embodiment, when the two sets of driving components 702 move relative to each other along the linear direction of the slide rail 4 and drive the rotating shaft 9 to rotate, the rotating shaft 9 drives the sleeve 19 and the slide rod 20 to rotate synchronously. During this process, the slide rod 20 can slide relative to the sleeve 19 along its axis, thereby keeping the connecting rod 15 swinging in its vertical plane. The connecting rod 15 can squeeze or pull the cantilever 14, thereby driving the swing arm 11 to deflect upward or downward through the cantilever 14. During the swing of the swing arm 11, the tooling table 2 can be driven to rotate relative to the base 3.

[0058] Compared to the previous embodiment, this solution adjusts the angle of the tooling table 2 by means of linkage 15:

[0059] On the one hand, once the tooling table 2 and the casting 13 are adjusted to a certain angle and locked, this structure can better support the casting 13, thereby ensuring the stability of the casting 13 during processing. On the other hand, compared with the adjustment method of the gear structure, this scheme has a smaller transmission error, making the angle adjustment of the tooling table 2 more precise.

[0060] Furthermore, one end of the swing arm 11 is rigidly fixed to the outer wall of the support 202, while the other end extends radially outward along the support 202, forming a long lever arm structure. The rotating shaft 9 outputs driving force to the cantilever 14 through the sleeve 19, slide rod 20, and connecting rod 15. The force acts on the extended end of the swing arm 11 away from the support 202. The rotational resistance of the tooling table 2, the support 202, and the casting 13 is concentrated at the rotation center of the support 202, forming a lever transmission relationship. Under the same driving force input conditions, the longer the lever arm, the greater the driving torque obtained at the rotation center. This structure applies the driving force to the outer end of the swing arm 11 away from the rotation center, effectively amplifying the driving torque and significantly reducing the output torque required to drive the rotating shaft 9.

[0061] Combined with appendix Figure 2 Appendix Figure 3 As shown, multiple sets of support members 301 are fixedly installed on the outer circumferential wall of the base 3; the lower end of the support member 301 and the bottom of the base 12 are both equipped with sliders, which are slidably mounted on the slide rail 4. An arc-shaped clearance groove 302 is opened on the outer circumference of the base 3, through which the swing arm 11 can pass and rotate circumferentially relative to the base 3 with the tooling table 2. A bushing 10 is fixedly installed on the outer side of the base 3 along the axial direction of the rotating shaft 9. The rotating shaft 9 is rotatably assembled with the bushing 10 via bearings to achieve rotational support of the rotating shaft 9 relative to the base 3.

[0062] Combined with appendix Figure 4 As shown, both ends of the connecting rod 15 are fixed with second pins 1501. The axis of the second pins 1501 is parallel to the axis of the sleeve 19. The connecting rod 15 is rotatably engaged with the hinge seat 16 through the second pins 1501. The end of the slide rod 20 is fixed with a first pin 17. The slide rod 20 is hinged to the adapter 18 through the first pin 17. The orthogonal hinge structure of the first pin 17 and the second pin 1501 can form spatial multi-degree-of-freedom compensation, preventing motion interference and jamming between the connecting rod 15 and the slide rod 20 during the movement of the connecting rod 15 pushing and pulling the cantilever 14.

[0063] See attached document Figure 5 As shown, the vertical sidewall of the base 12 has a slot for accommodating the sleeve, and bosses are fixed on both sides of the slot. A third pin 23 is fixed on the outer surface of the sleeve. The third pin 23 is parallel to the axis of the rotating shaft 9, and the third pin 23 and the two bosses form a rotating pair. When the two sets of bases 12 slide relative to each other along the slide rail 4 in opposite directions, the sleeve can deflect relative to the base 12 by relying on the third pin 23, synchronously driving the rod to complete the angular swing and smoothly transmit the horizontal thrust.

[0064] Combined with appendix Figure 1 Appendix Figure 8 As shown, this invention provides two implementation methods for the rotational support of the tooling table 2: First implementation method: Multiple rollers are evenly distributed on the inner circular wall of the base 3. The rollers are equidistantly arranged along the circumference of the base 3 and roll in contact with the outer circular surface of the support part 202. Rolling friction reduces the rotational resistance of the tooling table 2, ensuring that the tooling table 2 rotates flexibly and smoothly relative to the base 3. Second implementation method: An annular component 303 is fixed to the end of the base 3, and a turntable 203 is fixed to the end of the tooling table 2. The turntable 203 is rotatably assembled inside the annular component 303. The annular component 303 provides full-circumferential limiting support for the turntable 203, which improves the connection rigidity and movement stability of the tooling table 2 when carrying the casting 13.

[0065] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
