Description

Technical Field

[0001] This application relates to the field of machining tooling technology, and in particular to a vibration-resistant clamping device for CNC vertical lathe machining of large disc-shaped rotating parts for metallurgical equipment. Background Technology

[0002] Large disc-shaped and ring-shaped rotating parts used in the metallurgical industry, especially large-diameter labyrinth seal rings for rolling mills, are generally characterized by large diameter, relatively thin wall thickness, large self-weight load, and weak structural rigidity. These workpieces are divided into two structures: integral forging and machining, and welding with inner and outer ring stiffening plates. Welded workpieces also have obvious residual welding stress, making them extremely prone to deformation and vibration during processing.

[0003] Currently, when CNC vertical lathes process large disc-shaped workpieces, traditional clamping methods often use a few fixed support points combined with single-point pressure plates, which have significant technical defects: First, the workpiece's own weight and residual stress easily cause end face warping and local suspension, resulting in hidden deformation after clamping and excessive springback after release. Second, during the vertical lathe's rotary cutting process, the large cutting impact and insufficient system rigidity easily lead to problems such as cutting chatter, end face tool marks, and roundness deviations. Third, some eccentric discs and unevenly welded rings have unbalanced rotational mass, which intensifies vibration during high-speed rotation, seriously affecting dimensional accuracy and surface quality. Fourth, existing tooling is mostly a rigid support structure without vibration damping, multi-point independent leveling, or dynamic balancing compensation capabilities, resulting in poor adaptability and low machining pass rate.

[0004] Meanwhile, existing high-precision tooling mostly relies on hydraulic servo and electronic sensor closed-loop control, which is complex in structure, has high maintenance costs, and poor workshop adaptability, making it unsuitable for the processing conditions of heavy machinery with multiple varieties, small batches, and high dust. Therefore, there is an urgent need to design a vertical lathe anti-vibration clamping tooling with a purely mechanical structure, built-in vibration reduction, multi-point independent leveling, and mechanical dynamic balance compensation function.

[0005] Therefore, this application provides a vibration-resistant clamping device for CNC vertical lathe machining of large disc-shaped rotating parts for metallurgical equipment. Summary of the Invention

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. The anti-vibration clamping device for CNC vertical lathe machining of large disc-shaped rotating parts for metallurgical equipment, as described in this application, comprises a mechanical dynamic balance counterweight adjustment base, a multi-point independent micro-adjustment anti-vibration support mechanism, a circumferential support mechanism, and a mechanical preload locking clamping mechanism. When machining annular rotating parts, the device places the annular rotating part on the upper surface of multiple adjusting pads. Then, according to the actual situation, multiple lifting turntables are rotated. The rotation of the lifting turntables drives the rotating rod to rotate, which in turn drives the worm gear to rotate. The rotation of the worm gear drives the worm wheel and threaded column to rotate, and the rotation of the threaded column drives the internal threaded cylinder to automatically rise and fall, thereby achieving micro-adjustment of the position of the adjusting pads. This effectively compensates for the self-weight deflection and residual stress deformation of large disc-shaped and welded annular workpieces, improves uneven workpiece stress and local suspension problems, enhances workpiece machining accuracy, and avoids excessive springback. Combined with damping anti-vibration pads and multi-point evenly distributed supports... The structure and overall rigidity of the tooling are strong, effectively absorbing cutting vibrations, eliminating machining chatter marks, and improving workpiece machining quality and tool life. After adjustment, multiple drive turntables are rotated, which in turn drive the lead screw to rotate. The rotation of the lead screw drives the Z-shaped clamping plate to move, effectively limiting the outer periphery of the annular rotating part and achieving the purpose of rough alignment of the outer circle of large disc-shaped workpieces, limiting the horizontal radial offset of the workpiece. Then, the hydraulic rod can be activated to drive the transverse pressure plate to move downward, effectively limiting the vertical movement of the annular rotating part and preventing vertical vibration. Moreover, the mechanical dynamic balance counterweight adjustment base can adaptively compensate for the unbalanced force of the workpiece rotation, effectively solving the problem of chatter during high-speed machining of eccentric and non-uniform annular parts. This makes the tooling highly versatile and adaptable to various specifications of large metallurgical rotating workpieces. No separate customization is required, production costs are low, and it is suitable for enterprises' needs for multi-variety, small-batch production.

[0032] 2. The anti-vibration clamping device for CNC vertical lathe machining of large disc-shaped rotary parts in metallurgical equipment described in this application, by setting up a cleaning mechanism, can drive the lifting plate to move downward during the process of the hydraulic rod driving the transverse pressure plate to move downward, and squeeze the press-type air pump, so that the press-type air pump inflates the inside of the transverse air pipe through the air inflating pipe, and the airflow is sprayed out through two sets of jet nozzles to the surface of the annular rotary part, thereby realizing automatic cleaning of the surface of the annular rotary part at the contact part of the transverse pressure plate, avoiding the accumulation of dust and debris on the surface of the annular rotary part, which would cause damage to the surface of the annular rotary part when the transverse pressure plate presses down on the annular rotary part.

[0066] In this embodiment, by setting up a mechanical dynamic balance counterweight adjustment base 100, a multi-point independent micro-adjustment anti-vibration support mechanism 200, a circumferential support mechanism 300, and a mechanical preload locking clamping mechanism 400, when processing the annular rotating part 500, the annular rotating part 500 can be placed on the upper surface of multiple adjustment pads 202. Then, according to the actual situation, multiple lifting turntables 203 are rotated respectively. The rotation of the lifting turntables 203 drives the rotating rod 208 to rotate, the rotation of the rotating rod 208 drives the worm gear 209 to rotate, the rotation of the worm gear 209 drives the worm wheel 2010 and the threaded column 204 to rotate, and the rotation of the threaded column 204 drives the internal threaded cylinder 205 to automatically rise and fall, thereby realizing the micro-adjustment of the position of the adjustment pads 202. This can effectively compensate for the self-weight deflection and residual stress deformation of large disc-shaped and welded annular workpieces, improve the problem of uneven workpiece stress and local suspension, improve the workpiece processing accuracy, and avoid excessive processing springback. Combined with damping anti-vibration pads and a multi-point evenly distributed support structure, this achieves the desired effect. The tooling has high overall rigidity, which can effectively absorb cutting vibration, eliminate machining chatter marks, improve workpiece machining quality and tool life.

Then, the hydraulic rod 402 can be activated to drive the transverse pressure plate 401 to move downward, effectively limiting the vertical movement of the annular rotating part 500 and preventing it from vibrating vertically. Moreover, the mechanical dynamic balance counterweight adjustment base 100 can adaptively compensate for the unbalanced force of the workpiece rotation, effectively solving the problem of high-speed machining chatter of eccentric and non-uniform annular parts. This makes the tooling highly versatile and adaptable to various specifications of large metallurgical rotating workpieces. No separate customization is required, the production cost is low, and it is suitable for enterprises' multi-variety, small-batch production needs.

[0067] Example 2

[0068] Based on Example 1, referring to Figures 6 to 9 And unlike Example 1, the following is true:

[0069] Please refer to this carefully. Figure 7 , Figure 9 A cleaning mechanism 600 is provided on the lower surface of the transverse pressure plate 401. The cleaning mechanism 600 includes a rectangular groove opened on the lower surface of the transverse pressure plate 401 and a transverse air pipe 601 fixed on the inner wall of the rectangular groove. Two sets of jet heads 602 corresponding to the upper surface of the annular rotating member 500 are symmetrically arranged on the lower surface of the transverse air pipe 601.

[0070] Specifically, the device can automatically clean dust particles on the surface of the annular rotating component 500 by using two sets of jet nozzles 602 on the transverse air pipe 601.

[0071] Please refer to this carefully. Figure 7 , Figure 9 The cleaning mechanism 600 also includes a fixing plate 603 fixed to the side of the L-shaped mounting rod 403, and a press-type air pump 604 fixed to the upper surface of the fixing plate 603. The press-type air pump 604 has a return spring 605 inside. A lifting plate 606 is fixed to the end of the transverse pressure plate 401. The lower surface of the lifting plate 606 is fixedly connected to the pressing end of the press-type air pump 604. The top of the press-type air pump 604 is provided with suction pipes 607. The air inlet pipe 607 extends into the interior of the press-type air pump 604, and the other end of the air inlet pipe 607 extends into the upper surface of the lifting plate 606 and is threadedly connected to a mesh filter cover.

The surfaces of the air inlet pipe 607 and the air inlet pipe 608 are respectively provided with an air inlet check valve and an air inlet check valve.

[0072] Specifically, as the transverse pressure plate 401 moves downward, it can drive the lifting plate 606 to move downward and squeeze the press-type air pump 604, so that the press-type air pump 604 inflates the interior of the transverse air pipe 601 through the air pipe 608.

[0073] In this embodiment, by setting up a cleaning mechanism 600, during the process of the hydraulic rod 402 driving the transverse pressure plate 401 to move downward, the lifting plate 606 can be driven to move downward and squeeze the press-type air pump 604, so that the press-type air pump 604 inflates the interior of the transverse air pipe 601 through the air pipe 608, and the airflow is sprayed out through the two sets of jet nozzles 602 to the surface of the annular rotating part 500, thereby realizing automatic cleaning of the surface of the annular rotating part 500 at the contact part of the transverse pressure plate 401, avoiding the accumulation of dust and debris on the surface of the annular rotating part 500, which would cause damage to the surface of the annular rotating part 500 when the transverse pressure plate 401 presses down on it.
