Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, and in particular to a center conductor fixing device and a CNC lathe. Background Technology

[0002] Currently, in the processing of high-voltage center conductors, the common method is to use a combination of CNC lathes and milling-turning machines. However, this method suffers from significant efficiency issues in practice. Specifically, under the existing processing flow, only one high-voltage center conductor can be processed per operation. This means that when facing batch production tasks, a considerable amount of time is required to complete the processing of all products, severely limiting the expansion of production scale and the increase in production speed.

[0003] When machining high-voltage center conductors using CNC lathes and milling-turning machines, soft-jaw clamping is typically used to secure the workpiece. During machining, multiple clamping operations are required to complete the machining of different parts. However, multiple clamping operations can easily lead to inaccurate positioning of the center conductor, as each clamping operation may introduce some error. As the number of clamping operations increases, these errors accumulate, ultimately causing a decrease in the workpiece's machining accuracy and preventing it from meeting the design dimensional tolerances. Furthermore, during clamping and machining, the workpiece's end face may collide with the fixture, machine tool components, etc., leaving dents and scratches on the end face, affecting the product's machining quality. Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the shortcomings in related technologies. This utility model provides a center conductor fixing device and a CNC lathe equipment.

[0005] This utility model provides the following technical solution: A center conductor fixing device includes a clamping assembly and a switching assembly.

[0006] The clamping assembly has a clamping part for clamping and fixing the center conductor to be processed; the switching assembly is disposed on the worktable of the CNC lathe equipment, the switching assembly includes a rotating seat, and the clamping assembly is mounted on the rotating seat; the switching assembly drives the rotating seat to rotate, which can drive the clamping assembly to rotate relative to the worktable of the CNC lathe equipment.

[0007] As a further improvement to the above technical solution, the clamping assembly includes a clamping seat and a pressure block. The clamping seat is fixedly mounted on the rotating seat, and the pressure block is assembled and connected to the clamping seat through a connector. The clamping seat is provided with a first arc-shaped groove for placing the center conductor to be processed, and the pressure block is provided with a second arc-shaped groove corresponding to the first arc-shaped groove. The first arc-shaped groove and the second arc-shaped groove are arranged opposite to each other to form a clamping part.

[0008] As a further improvement to the above technical solution, a positioning groove corresponding to the positioning step on the side wall of the central conductor is provided in the first arc-shaped groove.

[0009] As a further improvement to the above technical solution, the first arc-shaped groove is provided in multiple evenly distributed along the axis of rotation of the rotating seat.

[0010] As a further improvement to the above technical solution, multiple pressure blocks are evenly distributed along the axis of rotation of the rotating seat, and every two first arc-shaped grooves correspond to one pressure block.

[0011] As a further improvement to the above technical solution, the switching component also includes two oppositely arranged mounting seats, and the rotating seat is rotatably mounted between the two mounting seats. One of the mounting seats is provided with a drive motor, and the drive motor is connected to the rotating seat in a transmission manner.

[0012] As a further improvement to the above technical solution, the rotation axis of the rotating seat is parallel to the horizontal plane, and the axis of the central conductor installed in the clamping part is perpendicular to the rotation axis of the rotating seat.

[0013] As a further improvement to the above technical solution, both mounting bases are provided with sliders at their bottoms that correspond to the adjustment grooves on the worktable, and the sliders pass through the adjustment grooves.

[0014] As a further improvement to the above technical solution, multiple sliders are provided corresponding to the adjustment grooves.

[0015] The present invention also provides a CNC lathe device, including a center conductor fixing device as described in any of the above.

[0016] Compared with related technologies, the beneficial effects of this utility model are: The center conductor fixing device provided by this utility model is designed with full consideration of convenience and precision in the center conductor processing. Specifically, when it is necessary to process the two opposing surfaces of the center conductor, the operator first places the center conductor in the clamping part of the clamping assembly. The clamping part can clamp and fix the center conductor.

[0017] This allows the center conductor of the clamping assembly to be fixedly mounted on the worktable of the CNC lathe, with one of the surfaces of the center conductor to be machined placed within the machining range of the CNC lathe. In this way, the CNC lathe can machine this surface to meet the design requirements.

[0018] After machining, there is no need to remove the center conductor from the clamping assembly and re-clamp it. Instead, the operator simply uses the convenient function of the switching assembly to drive the rotating seat to rotate the clamping assembly. This ensures that the center conductor on the clamping assembly is smoothly flipped. After flipping, the other surface of the center conductor to be machined enters the machining range of the CNC lathe, at which point the CNC lathe can perform the same machining process on that surface.

[0019] Throughout the entire processing, the center conductor fixing device of this invention demonstrates its unique advantages. Since it eliminates the need for multiple clamping operations on the various surfaces of the center conductor to be processed, it effectively avoids errors and uncertainties that may be introduced by repeated clamping. This not only ensures extremely high processing accuracy on the multiple surfaces of the center conductor but also significantly improves processing efficiency and reduces production costs. Simultaneously, by reducing the number of times the center conductor needs to be handled and adjusted during clamping, it also effectively prevents bumps and scratches on the surfaces to be processed, thereby ensuring a high yield rate for the processed product.

[0029] like Figure 1 As shown, an embodiment of the present invention provides a center conductor fixing device, including a clamping assembly 200 and a switching assembly 300.

[0030] The clamping assembly 200 has a clamping part for clamping and fixing the center conductor 110 to be processed; the switching assembly 300 is disposed on the worktable 120 of the CNC lathe equipment, the switching assembly 300 includes a rotating seat 310, and the clamping assembly 200 is mounted on the rotating seat 310; the switching assembly 300 drives the rotating seat 310 to rotate, which can drive the clamping assembly 200 to rotate relative to the worktable 120 of the CNC lathe equipment.

[0031] The center conductor fixing device provided in this embodiment is designed with full consideration of convenience and accuracy in the processing of the center conductor 110. Specifically, when it is necessary to process the two opposing surfaces 111 of the center conductor 110, the operator first places the center conductor 110 in the clamping part of the clamping assembly 200. The clamping part can clamp and fix the center conductor 110.

[0032] This allows the center conductor 110 on the clamping assembly 200 to be fixedly mounted on the worktable 120 of the CNC lathe, with one of the surfaces 111 of the center conductor 110 to be machined placed within the machining range of the CNC lathe. In this way, the CNC lathe can machine the surface 111 to meet the design requirements.

[0033] After processing, there is no need to remove the center conductor 110 from the clamping assembly 200 and re-clamp it. Instead, the operator only needs to use the convenient function of the switching assembly 300 to drive the rotating seat 310 to rotate the clamping assembly 200. This ensures that the center conductor 110 on the clamping assembly 200 will rotate smoothly. After rotation, the other surface 111 of the center conductor 110 to be processed enters the processing range of the CNC lathe, at which point the CNC lathe can perform the same processing on the surface 111.

[0034] Throughout the processing, the center conductor fixing device of this embodiment demonstrates its unique advantages. Since multiple clamping operations on the multiple surfaces 111 to be processed of the center conductor 110 are eliminated, errors and uncertainties that may be introduced by multiple clamping operations are effectively avoided. This not only ensures that the processing accuracy of the multiple surfaces 111 to be processed of the center conductor 110 reaches an extremely high level, but also significantly improves processing efficiency and reduces production costs. Simultaneously, by reducing the number of times the center conductor 110 is handled and adjusted during clamping, bumps and scratches on its surfaces 111 to be processed are effectively avoided, thereby ensuring a high yield rate for the processed product.

[0035] In some specific embodiments, the clamping assembly 200 includes a clamping seat 210 and a pressure block 220. The clamping seat 210 is fixedly mounted on the rotating seat 310, and the pressure block 220 is assembled and connected to the clamping seat 210 via a connector, which may be a bolt or similar structure. The clamping seat 210 has a first arc-shaped groove 211 for placing the center conductor 110 to be processed, and the pressure block 220 has a second arc-shaped groove 221 corresponding to the first arc-shaped groove 211. The first arc-shaped groove 211 and the second arc-shaped groove 221 are arranged opposite to each other to form a clamping part. In actual operation, the center conductor 110 can be easily and reliably clamped by the combined action of the first arc-shaped groove 211 on the clamping seat 210 and the second arc-shaped groove 221 on the pressure block 220. This clamping method is not only stable, but also simple and efficient in operation, greatly improving processing efficiency and reducing processing errors and product defect rates caused by unstable clamping.

[0036] like Figure 2 As shown, in some specific embodiments, a positioning groove 212 corresponding to the positioning step on the side wall of the central conductor 110 is formed in the first arc-shaped groove 211. When the operator places the central conductor 110 between the first arc-shaped groove 211 and the second arc-shaped groove 221, the positioning step on the side wall of the central conductor 110 can naturally and accurately slide into the positioning groove 212. This process is not only fast but also accurate in positioning, requiring no additional adjustment or calibration. Through this design, the relative position between the central conductor 110 and the clamping part is quickly and accurately determined, greatly simplifying the clamping operation process.

[0037] This rapid positioning mechanism not only improves the clamping and fixing efficiency of the center conductor 110 in this embodiment, but also ensures stability and reliability during the clamping process. Because of accurate positioning, the center conductor 110 is less prone to shifting or shaking during processing, thereby ensuring processing quality and precision.

[0038] In some specific embodiments, the first arc-shaped groove 211 is evenly distributed in multiple locations along the axis of rotation of the rotating seat 310, which is intended to simultaneously clamp and fix multiple center conductors 110 to be processed.

[0039] In actual operation, the operator can easily place multiple center conductors 110 into these preset first arc-shaped grooves 211, and then use the matching pressure blocks 220 to firmly fix the center conductors 110 in the clamping part. Since the multiple first arc-shaped grooves 211 are evenly distributed along the axis of rotation, it can be ensured that each center conductor 110 maintains a relatively independent and stable state during the clamping process, avoiding mutual interference and influence.

[0040] The advantage of this design is that it allows CNC lathes to process multiple center conductors 110 simultaneously without having to clamp and process them one by one. This not only significantly shortens the overall processing time and improves the processing efficiency of the center conductors 110, but also effectively reduces the errors and defect rates that may occur due to frequent workpiece changes, thereby improving overall processing quality and production efficiency.

[0041] In some specific embodiments, multiple pressure blocks 220 are evenly distributed along the axis of rotation of the rotating seat 310, and every two first arc-shaped grooves 211 correspond to one pressure block 220; such a design ensures that when clamping the center conductor 110, each center conductor 110 can be located exactly within the clamping space formed by the two first arc-shaped grooves 211 and the corresponding pressure block 220.

[0042] This arrangement ensures that each center conductor 110 receives stable and reliable clamping force from both directions during clamping. This bidirectional clamping design not only enhances clamping stability but also effectively prevents the center conductor 110 from shifting or wobbling during processing.

[0043] In some specific embodiments, the switching assembly 300 further includes two opposing mounting bases 320, with the rotating base 310 rotatably mounted between the two mounting bases 320. One of the mounting bases 320 is equipped with a drive motor 330, which is drively connected to the rotating base 310. The drive motor 330 serves as a power source and is drively connected to the rotating base 310 via a transmission mechanism (such as gear transmission or belt transmission). When the drive motor 330 starts, the rotational power it generates is precisely transmitted to the rotating base 310 through the transmission mechanism, thereby driving the entire clamping assembly 200 to rotate automatically.

[0044] This automatic rotation design offers significant advantages over traditional manual rotation methods. It not only greatly reduces manpower and the workload of operators, but also enables more precise and rapid rotation control, thereby effectively improving the efficiency of this embodiment.

[0045] In some specific embodiments, the rotation axis of the rotating seat 310 is parallel to the horizontal plane, and the axis of the central conductor 110 installed in the clamping part is perpendicular to the rotation axis of the rotating seat 310. During actual processing, the central conductor 110 needs to rotate around the axis of the rotating seat 310 to achieve processing at different positions. If the axis of the central conductor 110 is not perpendicular to the rotation axis of the rotating seat 310, then during rotation, the central conductor 110 may make unnecessary contact with surrounding components due to angular deviation.

[0046] By designing the axis of the central conductor 110 to be perpendicular to the axis of rotation of the rotating seat 310, interference between the two mounting seats 320 and the rotating central conductor 110 can be effectively avoided. Because the mounting seat 320 is fixed, when the central conductor 110 rotates perpendicular to the axis of rotation of the rotating seat 310, its trajectory will maintain a relatively safe and stable distance from the mounting seat 320, preventing collisions or friction caused by angle issues.

[0047] This design also reduces the impact of components such as the mounting base 320 on the surface 111 of the center conductor 110 to be machined. During processing, the surface 111 of the center conductor 110 needs to maintain a high degree of flatness and precision; any minor interference can lead to a decrease in processing quality. By avoiding interference between the mounting base 320 and the center conductor 110, the surface 111 to be machined is not subjected to additional pressure, friction, or vibration, thereby ensuring the accuracy of processing and surface quality.

[0048] In some specific embodiments, the bottom of both mounting bases 320 is provided with sliders corresponding to the adjustment grooves 121 on the worktable 120, and the sliders pass through the adjustment grooves 121. In actual operation, the operator can easily drive the sliders to slide within the adjustment grooves 121 according to specific processing requirements. This sliding adjustment is not done blindly, but is based on a comprehensive consideration of the workpiece size, processing technology, and equipment performance. By sliding the sliders, the positions of the switching component 300 and the clamping component 200 on the worktable 120 can be precisely changed.

[0049] This position adjustment function has significant advantages. On the one hand, it allows the equipment to adapt to workpieces of different sizes and shapes, improving the equipment's versatility and processing range. On the other hand, when adjustments or optimizations to the processing technology are needed, operators can quickly change the position of the clamping assembly 200 through a simple slider operation, thereby meeting new processing requirements.

[0050] In some specific embodiments, multiple sliders are provided corresponding to the adjustment grooves 121, which makes it easier to ensure that the position adjustment process of the switching component 300 and the clamping component 200 is more stable and reliable.

[0051] The embodiments of this utility model also provide a CNC lathe equipment, which can be specifically divided into two-axis control CNC lathes, multi-axis control CNC lathes, etc., including the center conductor fixing device in the above embodiments. The CNC lathe equipment has all the beneficial effects of the center conductor fixing device, which will not be described in detail here.
