Description

Technical Field

[0001] This utility model relates to the field of valve body drilling technology, and in particular to a flipping positioning device for multi-face drilling of valve bodies. Background Technology

[0002] The valve body is a core component in fluid control systems and is widely used in petroleum, chemical, and water conservancy fields. Its surface usually needs to be machined with multiple channels in different directions to achieve functions such as fluid conduction and control. The multi-face drilling operation of the valve body is a key process to ensure the performance of the valve body and requires the use of special positioning devices to ensure drilling accuracy and efficiency.

[0003] In actual multi-face drilling operations, existing positioning devices have the following shortcomings:

[0004] On the one hand, the limiting structure of traditional devices is simple, and the valve body is fixed by simple clamps. It cannot form a stable constraint from multiple dimensions such as top, bottom, and sides. When drilling, the valve body is prone to shaking, which can cause hole position deviation. Moreover, the adaptability to different specifications of valve bodies is poor. When replacing the valve body, the clamps need to be readjusted, which is cumbersome.

[0005] On the other hand, existing devices are difficult to achieve precise valve body rotation, relying mostly on manual rotation or manual angle adjustment. This not only increases the labor intensity of operators, but also easily affects the subsequent drilling accuracy due to rotation angle errors. At the same time, manual intervention also reduces the overall operation efficiency, making it difficult to meet the needs of mass production. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a flipping positioning device for multi-face drilling of valve bodies, which overcomes the deficiencies of existing technologies and effectively solves the problems of unstable valve body fixation and poor adaptability caused by the single limiting structure of existing positioning devices, as well as low accuracy and low efficiency caused by reliance on manual flipping adjustment.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A flipping and positioning device for multi-face drilling of valve body includes a frame, a valve body placement seat is provided inside the frame, and adjacent primary limiting components are provided on the top outer wall of the valve body placement seat. A secondary limiting component is provided on the top outer wall of the frame above the valve body placement seat. A first spindle and a second spindle are respectively provided on the two outer walls of the valve body placement seat. A gear is fixedly connected to the outer wall of the first spindle. A rack is meshed on the bottom of the outer wall of the gear, and a first cylinder is fixedly connected to the outer wall of one end of the rack.

[0009] Preferably, a cylinder mounting seat is fixedly connected to the inner wall of one side of the frame by screws, and the first cylinder is installed through the inner wall of the cylinder mounting seat.

[0010] Preferably, the primary limiting component includes a clamp, a threaded sleeve, and a lead screw. The clamp is hinged to one side of the top outer wall of the valve body placement seat, the threaded sleeve is hinged to the other side of the top outer wall of the valve body placement seat, and the lead screw is screwed to the inner wall of the threaded sleeve. A limiting piece is provided on the outer wall of the lead screw, and the limiting piece is in close contact with the outer wall of one end of the clamp.

[0011] Preferably, the secondary limiting assembly includes a second cylinder, a lifting plate, a spring, a pressure plate, and a guide rod. The second cylinder is fixedly connected to the top outer wall of the machine frame by screws. The lifting plate is fixedly connected to the piston rod of the second cylinder. The spring is fixedly connected to the bottom outer wall of the lifting plate. The pressure plate for pressing down the valve body is fixedly connected to the bottom outer wall of the spring. The guide rod is disposed through the inner wall of the lifting plate and is fixedly connected to the top outer wall of the pressure plate.

[0012] Preferably, the outer walls of the first and second shaft columns are rotatably connected to bearing frames via bearings, and the bearing frames are fixedly connected to the bottom inner wall of the frame by screws.

[0013] Preferably, a PLC controller is fixedly connected to the top of the outer wall on the other side of the frame by screws, and the PLC controller is connected to both the second cylinder and the first cylinder by signal lines.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The flipping and positioning device for multi-face drilling of valve body designed in this paper has the following components: In the first-level limiting component, the clamp can quickly engage with the side of the valve body. After the lead screw is adjusted by the threaded sleeve, the limiting plate on its outer wall can tightly abut against one end of the clamp, forming a lateral constraint. In the second-level limiting component, the second cylinder drives the lifting plate to descend, the spring drives the pressure plate to press down on the top of the valve body, and the guide rod ensures that the pressure plate rises and falls smoothly, preventing the valve body from moving up and down. This dual limiting structure is compatible with valve bodies of different specifications, solves the problem of single limiting and poor adaptability of traditional devices, significantly improves the stability of the valve body during drilling, and reduces the hole position deviation rate.

[0016] 2. The flipping and positioning device for multi-face drilling of valve bodies designed in this paper drives the rack to move linearly through the piston rod of the first cylinder. The rack meshes with the gear on the first shaft column, which can drive the first shaft column and the valve body placement seat to rotate around the axis. The second shaft column cooperates with the bearing bracket to ensure smooth rotation. It replaces the manual flipping operation and solves the problems of low precision and low efficiency caused by the reliance on manual flipping in traditional devices. It not only reduces the labor intensity of operators, but also accurately controls the flipping angle, improves the continuity and precision of multi-face drilling, and meets the needs of mass production.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4Example 1: A flipping and positioning device for multi-face drilling of valve bodies includes a frame 1. A valve body placement seat 2 is disposed inside the frame 1. Adjacent primary limiting components 3 are disposed on the top outer wall of the valve body placement seat 2. A secondary limiting component 4 is disposed on the top outer wall of the frame 1 above the valve body placement seat 2. The primary limiting component 3 includes a clamp 31, a threaded sleeve 32, and a lead screw 33. The clamp 31 is hinged to one side of the top outer wall of the valve body placement seat 2, the threaded sleeve 32 is hinged to the other side of the top outer wall of the valve body placement seat 2, and the lead screw 33 is screwed onto the inner wall of the threaded sleeve 32. A limiting plate is provided, and the limiting plate is tightly attached to the outer wall of one end of the clamp 31. The secondary limiting assembly 4 includes a second cylinder 41, a lifting plate 42, a spring 43, a pressure plate 44, and a guide rod 45. The second cylinder 41 is fixedly connected to the top outer wall of the frame 1 by screws. The lifting plate 42 is fixedly connected to the piston rod of the second cylinder 41. The spring 43 is fixedly connected to the bottom outer wall of the lifting plate 42. The pressure plate 44, which is used to press down the valve body, is fixedly connected to the bottom outer wall of the spring 43. The guide rod 45 is provided through the inner wall of the lifting plate 42 and is fixedly connected to the top outer wall of the pressure plate 44.

[0024] In this embodiment, after placing the valve body to be drilled on the valve body placement seat 2, the clamp 31 is rotated to fasten it to the side of the valve body. Then, the lead screw 33 is rotated. Since the lead screw 33 is screwed to the threaded sleeve 32, the lead screw 33 will move axially along the threaded sleeve 32 until the limiting piece on its outer wall tightly fits one end of the clamp 31, fixing the clamp 31 and achieving the limiting of the side of the valve body. Subsequently, the second cylinder 41 of the secondary limiting component 4 is activated. The piston rod of the second cylinder 41 pushes the lifting plate 42 to move downward. The lifting plate 42 drives the spring 43 and the pressure plate 44 to descend synchronously. After the pressure plate 44 contacts the top of the valve body, the spring 43 is compressed and generates continuous downward pressure to ensure that the pressure plate 44 stably presses the valve body. At the same time, the guide rod 45 slides along the inner wall of the lifting plate 42 to ensure that the pressure plate 44 does not deviate during the lifting process, forming an effective constraint on the valve body from the top.

[0025] Example 2: A flipping and positioning device for multi-face drilling of valve body. The valve body placement seat 2 has a first shaft column 5 and a second shaft column 10 respectively provided on the outer walls of both sides. A gear 6 is fixedly connected to the outer wall of the first shaft column 5. A rack 7 is meshed at the bottom of the outer wall of the gear 6. A first cylinder 8 is fixedly connected to the outer wall of one end of the rack 7. A cylinder mounting seat 9 is fixedly connected to the inner wall of one side of the frame 1 by screws. The first cylinder 8 is installed through the inner wall of the cylinder mounting seat 9.

[0026] In this embodiment, the cylinder mounting base 9 is fixed to the inner wall of one side of the frame 1 by screws, providing a stable mounting base for the first cylinder 8 and preventing the first cylinder 8 from shaking during operation. The first cylinder 8 is installed through the inner wall of the cylinder mounting base 9 to ensure that the extension and retraction direction of its piston rod remains straight. When the first cylinder 8 is started, the piston rod can drive the rack 7 to move stably in the horizontal direction. The rack 7 meshes with the gear 6 on the first shaft column 5. The linear motion of the rack 7 is converted into the rotational motion of the gear 6, which in turn drives the first shaft column 5 to rotate, providing power for the flipping of the valve body placement seat 2.

[0027] Bearing brackets 11 are rotatably connected to the outer walls of the first shaft column 5 and the second shaft column 10 via bearings, and the bearing brackets 11 are fixedly connected to the bottom inner wall of the frame 1 by screws.

[0028] Through the above scheme, the bearing bracket 11 is fixed to the inner wall of the bottom of the frame 1 with screws to ensure the stability of the overall structure; the first shaft column 5 and the second shaft column 10 are respectively connected to the corresponding bearing bracket 11 through bearings. The bearings can greatly reduce the friction when the shaft column rotates, making the first shaft column 5 and the second shaft column 10 drive the valve body placement seat 2 to flip more smoothly. At the same time, the bearings can also play a radial positioning role for the shaft column, preventing the shaft column from shifting during rotation and ensuring the accurate flipping angle of the valve body placement seat 2.

[0029] A PLC controller 12 is fixedly connected to the top of the outer wall on the other side of the frame 1 by screws, and the PLC controller 12 is connected to the second cylinder 41 and the first cylinder 8 by signal lines.

[0030] Through the above scheme, the operator can preset the operating parameters of the second cylinder 41 and the first cylinder 8 through the PLC controller 12, such as the lifting stroke and lifting speed of the piston rod of the second cylinder 41, and the extension stroke and extension speed of the piston rod of the first cylinder 8. When the device is running, the PLC controller 12 sends control signals to the second cylinder 41 and the first cylinder 8 through the signal line, and precisely controls the second cylinder 41 to drive the pressure plate 44 to press or release the valve body, and the first cylinder 8 to drive the valve body placement seat 2 to flip, so as to realize the automated control of the entire positioning and flipping process.

[0031] Working principle: First, the operator places the valve body to be drilled on the valve body placement seat 2. The PLC controller 12 sends a signal to the second cylinder 41 of the secondary limit component 4. The piston rod of the second cylinder 41 pushes the lifting plate 42 down. The lifting plate 42 drives the pressure plate 44 to press down on the top of the valve body through the spring 43. The guide rod 45 ensures that the pressure plate 44 rises and falls smoothly. At the same time, the clamp 31 of the primary limit component 3 is manually rotated to fasten the side of the valve body. Then the lead screw 33 is rotated so that the limiting piece on the outer wall of the lead screw 33 is tightly attached to one end of the clamp 31, thus completing the multi-dimensional limiting and fixing of the valve body.

[0032] When drilling is required on the other side of the valve body, the PLC controller 12 sends a signal to the first cylinder 8. Supported by the cylinder mounting seat 9, the piston rod of the first cylinder 8 drives the rack 7 to move linearly. The rack 7 meshes with the gear 6 on the first shaft column 5, driving the first shaft column 5 to rotate. At the same time, the second shaft column 10 rotates synchronously under the bearing support of the bearing bracket 11, causing the valve body placement seat 2 and the valve body to be precisely rotated to the preset angle.

[0033] After the flipping is completed, the PLC controller 12 controls the first cylinder 8 to stop running, keeping the current angle of the valve body stable, so that the drilling operation on the next side can be carried out; after all sides are drilled, the PLC controller 12 controls the piston rod of the second cylinder 41 to retract, driving the pressure plate 44 to rise and release the valve body. The screw 33 is manually adjusted and the clamp 31 is opened, so that the processed valve body can be taken out.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
