Description

Technical Field

[0001] This utility model belongs to the technical field of polishing devices, specifically relating to a polishing device adapted to curved surface polishing. Background Technology

[0002] Currently, curved surface polishing equipment mainly employs adaptive pressure adjustment and curvature compensation technology. These are primarily categorized as: mechanically floating type, airbag polishing machine, multi-axis linkage contouring machine, and special-purpose machine for hyperboloid surfaces. Through a support arm and sliding guide arm design, the polishing workpiece floats along the guide arm via a spring-loaded elastic connection, automatically conforming to different curvature areas.

[0003] A curved surface polishing machine is disclosed in the utility model patent with patent authorization announcement number CN206200718U, including a box component, a transmission body, a support plate, an upper plate device, a linear slide rail, a slide base, and a lifting component. The transmission body, the linear slide rail, and the lifting component are fixed on the box component. The lifting component is connected to the slide base, and the slide base is connected to the linear slide rail. The support plate is fixed on the slide base, and the upper plate device is fixed on the support plate. A brush plate is provided on the upper plate of the upper plate device. A rotary component is provided on the transmission body. The rotary component can perform both revolution and rotation.

[0004] However, existing polishing devices adapted to curved surfaces also have certain drawbacks. Although existing polishing devices adapted to curved surfaces use a combination of hydraulic cylinders, springs, grinding parts, and other structures to polish the workpiece, the friction between the cylinder body and the telescopic end can easily cause a large resistance to the subsequent extension and retraction of the hydraulic cylinder. Summary of the Invention

[0005] The purpose of this invention is to provide a polishing device adapted to curved surfaces. It solves the problem that existing polishing devices adapted to curved surfaces, although using hydraulic cylinders, springs, grinding parts and other structures to polish workpieces, are prone to large resistance to subsequent extension and retraction of the hydraulic cylinder due to the material friction between the cylinder body and the telescopic end.

[0006] To achieve the above objectives, this utility model provides a polishing device adapted for curved surfaces, including a support table, a workpiece placed on the table surface of the support table, a support frame fixedly connected to the table surface of the support table, a hydraulic cylinder fixedly mounted on the horizontal part of the support frame, the telescopic end of the hydraulic cylinder being slidably connected to the horizontal part of the support frame, a fixed seat fixedly connected to the telescopic end of the hydraulic cylinder, a curved surface polishing mechanism being provided on the fixed seat, a first guide hole being opened on the horizontal part of the support frame, an oil reservoir being fixedly connected to the horizontal part of the support frame and located to the right of the hydraulic cylinder, a second guide hole being opened on the inner bottom of the oil reservoir, an end piece being slidably connected to the inner wall of the oil reservoir, a sealing head being fixedly connected to the lower end of the end piece, and the sealing head being slidably connected to the second guide hole.

[0007] The principle of this utility model is as follows: the telescopic end is moved by the hydraulic cylinder to drive the fixed seat to move down, so that the guide plate slides along the inner wall of the support frame, and guides the fixed seat, connecting frame and other components to move and guide, so that the grinding head contacts the curved surface of the workpiece. Due to the different curvature of the workpiece surface, and with the deformation of the second spring, the grinding head at different positions can always contact and fit with the curved surface of the workpiece. When the servo motor drives the output shaft to rotate, it can drive the connecting frame to rotate, which in turn drives the crossbeam to rotate, and drives the telescopic plate to rotate, so that the grinding head slides along the curved surface of the workpiece to perform adaptive grinding and polishing of the workpiece. By pulling the end piece upwards, the sealing head is moved, causing the spring to deform and ultimately disengage from the guide hole. With the cooperation of the guide hole and the guide hole, the lubricating oil can be guided and circulated, allowing the lubricating oil to come into contact with the oil suction block. Under the adsorption of the oil suction block, the lubricating oil can finally come into contact with the extension and retraction end of the hydraulic cylinder, thus lubricating the hydraulic cylinder and reducing the extension and retraction resistance of the hydraulic cylinder.

[0008] The beneficial effects of this utility model are as follows: This solution uses the extension and retraction of the hydraulic cylinder to drive the fixed seat to move, so that the guide plate slides along the inner side wall of the support frame, thereby ensuring the stability of the movement of subsequent fixed seats, connecting frames and other components. Under the deformation of spring two, the grinding head can be tightly fitted with the curved surface of the workpiece. With the driving action of the servo motor, the curved surface of the workpiece can be adaptively ground. By pulling the end plate upward, the sealing head is moved, causing spring one to deform, and finally the guide hole two is in a conductive state. With the action of guide hole one, oil suction block and other structures, the extension and retraction end of the hydraulic cylinder can be lubricated to reduce the extension and retraction resistance of the hydraulic cylinder.

[0009] Furthermore, an oil-absorbing block is fixedly connected to the top inner side of the support frame. The oil-absorbing block is slidably connected to the telescopic end of the hydraulic cylinder. By setting the oil-absorbing block, lubricating oil can be absorbed and used to lubricate the telescopic end of the hydraulic cylinder.

[0010] Furthermore, the second guide hole is located directly above the first guide hole, and the diameter of the second guide hole is the same as that of the first guide hole. Through the combined use of the second guide hole and the first guide hole, the lubricating oil can be channeled.

[0011] Furthermore, a spring is welded to the horizontal part of the end piece, and the other end of the spring is welded to the end block of the inner side wall of the oil reservoir. The spring can be used to tighten the end piece.

[0012] Furthermore, the curved surface polishing mechanism includes a guide plate. The guide plate is fixedly connected to the lower horizontal part of the fixed base. The guide plate is slidably connected to the inner wall of the support frame. A servo motor is fixedly installed at the bottom inner side of the fixed base. The output shaft of the servo motor is rotatably connected to the lower horizontal part of the fixed base. A connecting frame is fixedly connected to the output shaft of the servo motor. A crossbeam is fixedly connected to the vertical part of the connecting frame. A telescopic plate is slidably connected to the inner wall of the crossbeam. A grinding head is fixedly connected to the lower end of the telescopic plate. The grinding head contacts the curved surface of the workpiece. A second spring is welded to the upper end of the telescopic plate. The other end of the second spring is welded to the top inner side of the connecting frame. Through the combined use of the servo motor, connecting frame, and other structures, the grinding head can be driven to rotate. With the deformation of the second spring, the adaptive contact and grinding effect between the grinding head and the curved surface of the workpiece can be ensured.

[0013] Furthermore, two guide plates are provided, which are symmetrically distributed on the fixed base. The fixed base can be moved and guided by the guide plates.

[0014] Furthermore, multiple telescopic plates are provided, and the multiple telescopic plates are evenly distributed on the crossbeam. The telescopic plates can be used to connect and connect the grinding head. Attached Figure Description

Detailed Implementation

[0017] The implementation examples are basically as follows Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, this embodiment provides a polishing device adapted to curved surfaces, including a support table 1, a workpiece 2 on the table surface of the support table 1, a support frame 3 fixedly connected to the table surface of the support table 1, a hydraulic cylinder 4 fixedly installed on the horizontal part of the support frame 3, the telescopic end of the hydraulic cylinder 4 slidably connected to the horizontal part of the support frame 3, a fixed seat 5 fixedly connected to the telescopic end of the hydraulic cylinder 4, a guide hole 8 opened on the horizontal part of the support frame 3, an oil reservoir 9 fixedly connected to the horizontal part of the support frame 3 and located on the right side of the hydraulic cylinder 4, a guide hole 10 opened on the bottom inner side of the oil reservoir 9, an end piece 11 slidably connected to the inner wall of the oil reservoir 9, a sealing head 12 fixedly connected to the lower end of the end piece 11, and the sealing head 12 slidably connected to the guide hole 10.

[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, an oil suction block 7 is fixedly connected to the top inner side of the support frame 3. The oil suction block 7 is slidably connected to the telescopic end of the hydraulic cylinder 4. By setting the oil suction block 7, lubricating oil can be absorbed and used to lubricate the telescopic end of the hydraulic cylinder 4. The second guide hole 10 is located directly above the first guide hole 8. The diameter of the second guide hole 10 is the same as that of the first guide hole 8. By using the second guide hole 10 and the first guide hole 8 together, lubricating oil can be channeled. A spring 13 is welded to the horizontal part of the end piece 11. The other end of the spring 13 is welded to the end block of the inner wall of the oil reservoir 9. By setting the spring 13, the end piece 11 can be tightened.

[0019] like Figure 1 , Figure 2 , Figure 3 As shown, a curved surface polishing mechanism 6 is provided on the fixed base 5. The curved surface polishing mechanism 6 includes a guide plate 60. The guide plate 60 is fixedly connected to the lower horizontal part of the fixed base 5. The guide plate 60 is slidably connected to the inner wall of the support frame 3. A servo motor 61 is fixedly installed on the inner bottom of the fixed base 5. The output shaft of the servo motor 61 is rotatably connected to the lower horizontal part of the fixed base 5. The output shaft of the servo motor 61 is fixedly connected to a connecting frame 62. A crossbeam 63 is fixedly connected to the vertical part of the connecting frame 62. The crossbeam 63... A telescopic plate 64 is slidably connected to the inner wall. A grinding head 65 is fixedly connected to the lower end of the telescopic plate 64. The grinding head 65 contacts the curved surface of the workpiece 2. A second spring 66 is welded to the upper end of the telescopic plate 64. The other end of the second spring 66 is welded to the inner top of the connecting frame 62. Through the cooperation of the servo motor 61, the connecting frame 62 and other structures, the grinding head 65 can be driven to rotate. With the deformation of the second spring 66, the adaptive contact and grinding effect between the grinding head 65 and the curved surface of the workpiece 2 can be guaranteed.

[0020] like Figure 1 , Figure 2 , Figure 3As shown, there are two guide plates 60, which are symmetrically distributed on the fixed seat 5. The fixed seat 5 can be moved and guided by the guide plates 60. There are multiple telescopic plates 64, which are evenly distributed on the crossbeam 63. The grinding head 65 can be connected and used by the telescopic plates 64.

[0021] The specific implementation process of this utility model is as follows: The hydraulic cylinder 4 drives the telescopic end to move, thereby driving the fixed seat 5 to move down, so that the guide plate 60 slides along the inner wall of the support frame 3, and moves and guides the fixed seat 5, connecting frame 62 and other components, so that the grinding head 65 contacts the curved surface of the workpiece 2. Due to the different curvature of the curved surface of the workpiece 2, and with the deformation action of the spring 66, the grinding head 65 at different positions can always contact and fit with the curved surface of the workpiece 2. When the servo motor 61 drives the output shaft to rotate, it can drive the connecting frame 62 to rotate, thereby driving the crossbeam 63 to rotate, and driving the telescopic plate 64 to rotate, thereby driving the grinding head 65 to slide along the curved surface of the workpiece 2, and performing adaptive grinding and polishing on the workpiece 2. By pulling the end piece 11 upward, the sealing head 12 is moved, causing the spring 13 to deform. Ultimately, the sealing head 12 is disengaged from the guide hole 10. With the cooperation of the guide hole 10 and the guide hole 8, the lubricating oil can be guided and circulated, allowing the lubricating oil to contact the oil suction block 7. Under the adsorption of the oil suction block 7, the lubricating oil can finally contact the extension end of the hydraulic cylinder 4, lubricating the hydraulic cylinder 4 and reducing the extension resistance of the hydraulic cylinder 4.

[0022] This solution uses the extension and retraction of hydraulic cylinder 4 to drive the fixed seat 5 to move, allowing the guide plate 60 to slide along the inner wall of the support frame 3, thus ensuring the stability of the movement of subsequent components such as the fixed seat 5 and the connecting frame 62. Under the deformation of spring 66, the grinding head 65 can be tightly fitted with the curved surface of the workpiece 2. With the driving action of servo motor 61, the curved surface of the workpiece 2 can be adaptively ground. By pulling end plate 11 upward, the sealing head 12 is moved, causing spring 13 to deform, ultimately making the guide hole 10 open. With the help of guide hole 8, oil suction block 7, and other structures, the extension and retraction end of hydraulic cylinder 4 can be lubricated to reduce the extension and retraction resistance of hydraulic cylinder 4.
