Description

Technical Field

[0001] This invention relates to the field of cutting technology, and in particular to a blank cutting device for ball screw machining. Background Technology

[0002] The field of cutting technology encompasses the related technologies, equipment, and application scenarios for separating and processing various metallic and non-metallic materials. Its core content involves using physical and chemical methods to divide materials into predetermined sizes and shapes to meet the needs of subsequent processing or direct use. Within this overall technology field, it covers various cutting methods selected based on different material properties and processing requirements, such as mechanical cutting and thermal cutting. Mechanical cutting includes sawing, milling, and shearing, while thermal cutting includes flame cutting, plasma cutting, and laser cutting. It also involves key components in the cutting process, such as positioning devices, clamping devices, feeding mechanisms, and cutting parameter control. It is widely used in various industries, including machinery manufacturing, automotive, aerospace, and construction, providing a basic material segmentation process for the production and processing of various parts, ensuring that subsequent processing steps can be carried out accurately and efficiently.

[0003] One type of blank cutting equipment for ball screw processing refers to specialized equipment used in the ball screw production process to cut ball screw blanks. The technical aspects addressed by this equipment include: selecting an appropriate cutting method based on the blank's material (e.g., steel alloy, diameter, length, etc.), typically employing mechanical sawing with a dedicated saw blade made of high-speed steel or cemented carbide depending on the blank material; setting up a blank positioning mechanism to position the blank axially and radially using V-blocks or positioning pins to ensure accurate cutting; equipping a blank clamping mechanism using hydraulic or pneumatic clamping to fix the blank and prevent loosening during cutting; setting up a feeding mechanism that uses a motor-driven screw or gear transmission to drive the saw blade or blank at a uniform speed, controlling the cutting speed; and including a cooling system that sprays coolant to cool the saw blade and cutting area, reducing cutting temperature and minimizing saw blade wear and blank thermal deformation.

[0004] Existing technologies only mention the use of mechanical sawing with dedicated saw blades, positioning and clamping feeding mechanisms, and cooling systems. They do not address the automatic billet conveying structure, which requires manual billet conveying, increasing labor intensity and making it susceptible to errors in conveying stability. Furthermore, the lack of a shielding structure to prevent dust and sparks from splashing during the cutting process leads to dust and sparks spreading and polluting the working environment, which can harm the health of operators. The positioning and clamping mechanism does not mention buffering and shock absorption design, which can easily cause excessive impact on the billet during clamping, resulting in billet damage or positioning deviation, affecting cutting accuracy and failing to guarantee cutting quality. Summary of the Invention

[0005] The main objective of this invention is to provide a blank cutting device for ball screw processing, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A blank cutting device for ball screw machining includes a cutting table and a control cabinet disposed on the upper part of the cutting table. The upper part of the cutting table is symmetrically provided with positioning and clamping structures for fixing the blank, and symmetrically provided with feeding structures for carrying the blank. The middle part of the upper part of the cutting table is provided with a cutting structure for cutting the blank, and the lower end of the cutting structure is provided with a shielding structure for shielding cutting dust and sparks. The control cabinet is provided with a controller and a drive device.

[0010] Preferably, the shielding structure includes a dustproof box installed on the outer surface of the vertical part of the T-shaped slider. The dustproof box is U-shaped, and a shielding curtain is fixedly connected to the inner walls of both sides. Several connecting wheels are arranged in an array at the ends of the two shielding curtains on the same side that are close to each other. Support components that are slidably connected to the outer surface of the adjacent connecting wheels are symmetrically arranged on the inner side of the dustproof box.

[0011] Preferably, the support assembly includes a sliding rod, the lower end of which extends through the upper end of the dustproof box and into the inner cavity of the dustproof box. A tension spring for resetting the sliding rod is sleeved on the outer surface of the upper end of the dustproof box. The outer surface of the sliding rod is symmetrically provided with connecting grooves that slide and connect with the outer surface of the adjacent connecting wheel. An arc-shaped plate for pressing the surface of the blank is fixedly connected to the lower end of the sliding rod. When the dustproof box moves downward with the T-shaped slider until the arc-shaped plate contacts the surface of the blank, the sliding rod moves upward relative to the dustproof box and pulls the sliding rod to generate displacement so that it covers the surface of the blank.

[0012] Preferably, the positioning and clamping structure includes a transmission component slidably mounted on the upper end of the cutting table, a clamping component for clamping the blank is provided on one side of the upper end of the cutting table, a cooperating link is rotatably connected to the side of the transmission component near the T-shaped slider and rotatably connected to the lower end of the horizontal part of the T-shaped slider, and a wedge plate for driving the clamping component is fixedly connected to the side of the transmission component away from the transmission component.

[0013] Preferably, the transmission assembly includes a push rod slidably connected to the upper end of the cutting table, the upper end of the push rod being rotatably connected to a cooperating link, a piston rod being fixedly connected to the end of the transmission assembly away from the cooperating link, a connecting rod being slidably connected to the outer surface of the piston rod and slidably connected to the upper end of the cutting table, a buffer spring sleeved on the outer surface of the piston rod being fixedly connected to the ends of the connecting rod and the push rod that are close to each other, and the end of the piston rod away from the push rod being fixedly connected to a wedge plate.

[0014] Preferably, the clamping assembly includes a base plate fixedly installed on the upper end of the cutting table, a buffer component for supporting the blank is provided in the middle of the upper end of the base plate, clamping arms are symmetrically slidably connected to the upper end of the base plate, spring limiting rods for limiting the sliding trajectory of the clamping arms are symmetrically provided on the upper end of the base plate, and a driving assembly for sliding the clamping arms on both sides is provided in the inner cavity of the base plate by being driven by a wedge plate.

[0015] Preferably, the drive assembly includes a gear rotatably connected to the inner surface of the base plate. The upper and lower parts of the outer surface of the gear are respectively meshed with racks. The two racks are respectively fixedly connected to the inner walls of adjacent clamping arms. The lower rack is fixedly connected to a hollow rod sleeved on the outer surface of the wedge plate. The inner wall of the hollow rod is rotatably connected to a roller that is in close contact with the inclined surface of the wedge plate. When the hollow rod moves under the action of the wedge plate, the two racks drive the clamping arms on both sides to produce relative displacement under the action of the gear.

[0016] Preferably, the buffer component includes a rectangular platform installed at the middle of the upper part of the base plate. The upper part of the rectangular platform is symmetrically provided with sliding grooves on the left and right sides. The inner surfaces of the two sliding grooves are slidably connected to support wheels for abutting the blank through springs. The bottom walls of the inner cavities of the two sliding grooves are fixedly connected with telescopic rods. The inner cavity of the telescopic rods is filled with non-Newtonian fluid and its movable rod abuts against the lower part of the outer surface of the support wheel.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This invention provides a stable foundation and power control for the equipment through the cooperation of the cutting table and the control cabinet. The feeding structure uses the feeding roller, drive shaft, trapezoidal support platform and anti-wear ball bearings to realize automatic feeding of the billet and protect its surface quality. The cutting structure uses the support frame, T-shaped slider, splash guard and saw blade to complete the precise cutting of the billet. The shielding structure wraps the saw blade to prevent dust and sparks from flying. The positioning and clamping structure realizes the stable fixation of the billet. All the structures work together to achieve efficient and safe cutting, improve cutting quality, reduce labor intensity and protect the working environment.

[0019] 2. This invention forms a closed space through the cooperation of the dustproof box and the shielding curtain in the shielding structure, preventing the spread of cutting dust and sparks. The cooperation between the shielding curtain and the connecting wheel reduces the deformation friction of the shielding curtain, allowing it to smoothly cover the blank. The cooperation between the support component and the dustproof box provides support for the shielding curtain. The cooperation between the sliding rod, tension spring and arc plate in the support component ensures that the arc plate fits tightly against the blank. The cooperation between the sliding rod and the connecting wheel drives the shielding curtain to deform precisely, achieving complete closure of the cutting area and protecting the operator and the working environment.

[0020] 3. This invention achieves power transmission through the cooperation of the transmission component and the coordinating linkage in the positioning and clamping structure. The cooperation of the push rod, piston rod and buffer spring in the transmission component avoids excessive impact on the billet. The cooperation of the base plate and clamping arm in the clamping component clamps the billet. The cooperation of the gear, rack and pinion and roller in the drive component realizes the relative movement of the clamping arm. The cooperation of the support wheel, spring and telescopic rod in the buffer component buffers and reduces shock. Finally, the billet is stably clamped, ensuring cutting accuracy.

Detailed Implementation

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] Example 1: A blank cutting device for ball screw machining, see reference. Figure 1The equipment includes a cutting table 1, which serves as the foundational load-bearing component, providing a stable installation and working platform for all other structures. A control cabinet 2 is located on top of the cutting table 1. The controller inside the control cabinet 2 receives and processes signals from various structures and issues commands to coordinate their orderly operation. Its internal drive system provides power to components requiring power, such as the feeding structure 6. Symmetrically arranged on the left and right sides of the upper end of the cutting table 1 are positioning and clamping structures 5 for fixing the blank. These structures precisely clamp and fix the blank before cutting, preventing displacement during the cutting process and ensuring cutting accuracy. They also act as a buffer to prevent blank deformation. The upper end is symmetrically equipped with a feeding structure 6 for carrying the blank. The feeding structure 6 can realize the automatic conveying of the blank, accurately conveying the blank to be processed to the cutting position and conveying the finished product out of the cutting area after cutting, which greatly improves the processing efficiency. The upper middle part of the cutting table 1 is equipped with a cutting structure 3 for cutting the blank. The cutting structure 3 is the core component for completing the blank cutting operation. Under the control of the controller, it can realize the lifting and high-speed rotation of the saw blade to complete the cutting action. The lower end of the cutting structure 3 is equipped with a shielding structure 4 for shielding cutting dust and sparks. The shielding structure 4 can confine dust and sparks in a closed space during the cutting process, effectively protecting the safety of operators and preventing pollution of the working environment.

[0034] For further details, please refer to [link / reference]. Figure 2 The feeding structure 6 includes a feeding roller 62 mounted on the upper end of the cutting table 1 via a bearing housing. The bearing housing ensures stable rotation of the feeding roller 62 and reduces frictional losses during rotation. A drive shaft 61 is fixedly connected to the front side of the feeding roller 62 and is connected to the drive equipment inside the control cabinet 2 via a transmission belt. When the drive equipment inside the control cabinet 2 is started, power is transmitted to the drive shaft 61 via the transmission belt. The drive shaft 61 then drives the feeding roller 62, which is fixedly connected to it, to rotate. During rotation, the feeding roller 62 generates friction with the outer surface of the blank, thereby driving the blank towards the cutting structure 3. The cutting table 1 is symmetrically fixed to the front and rear of the upper end to achieve automatic feeding. The upper side of the trapezoidal support table 63 is arc-shaped, which can better fit the cylindrical ball screw blank and ensure the stability of the blank when it is placed. The inner wall of the arc surface is rotatably connected to anti-wear balls 64 to reduce scratches. During the movement of the blank, the anti-wear balls 64 will rotate with it, converting the sliding friction between the blank and the trapezoidal support table 63 into rolling friction, which greatly reduces the scratch damage on the outer surface of the blank and effectively protects the processing accuracy and surface quality of the blank.

[0035] For further details, please refer to [link / reference]. Figure 3The cutting structure 3 includes a support frame 31 installed at the upper end. The support frame 31 provides a stable guide and support structure for the sliding of the T-shaped slider 32, ensuring that the T-shaped slider 32 can move accurately along the preset trajectory. The T-shaped slider 32 is slidably connected to the inner wall of the support frame 31. The T-shaped slider 32 is a key component that connects and drives the movement of multiple parts. A splash guard 33 is fixedly installed on the inner wall of its vertical part. The splash guard 33 can prevent sparks and dust from splashing to both sides during the cutting process, and plays a protective role for operators and other parts of the equipment. A saw blade 34 driven by a motor is rotatably installed on the inner surface of the splash guard 33. The motor can provide the saw blade 34 with high-speed rotation power, so that the saw blade 34 has sufficient cutting ability to smoothly cut the ball screw blank. The shielding structure 4 is installed on the outer surface of the vertical part of the T-shaped slider 32 and wraps the saw blade 34 inside the shielding structure 4. This can ensure that the dust and sparks generated during cutting are surrounded in all directions, further improving the protection effect.

[0036] In the operation of this embodiment, the cooperation between the cutting table 1 and the control cabinet 2 provides a stable foundation and power control for the equipment. The feeding roller 62, drive shaft 61, trapezoidal support platform 63 and anti-wear ball bearings 64 in the feeding structure 6 realize the automatic feeding of the billet and protect its surface quality. The support frame 31, T-shaped slider 32, splash guard 33 and saw blade 34 in the cutting structure 3 complete the precise cutting of the billet. The shielding structure 4 wraps the saw blade 34 to prevent dust and sparks from flying. The positioning and clamping structure 5 realizes the stable fixation of the billet. The cooperation of all structures realizes efficient and safe cutting, improves cutting quality, reduces labor intensity and protects the working environment.

[0037] Example 2: Based on Example 1, this example uses the dustproof box 41 and the shielding curtain 42 in the shielding structure 4 to form a closed space, preventing the spread of cutting dust and sparks. The shielding curtain 42 and the connecting wheel 421 reduce the deformation friction of the shielding curtain 42, allowing it to smoothly cover the blank. The support component 43 and the dustproof box 41 provide support for the shielding curtain 42. The sliding rod 432, the tension spring 431 and the arc plate 434 in the support component 43 ensure that the arc plate 434 fits tightly against the blank. The sliding rod 432 and the connecting wheel 421 drive the shielding curtain 42 to deform precisely, achieving complete enclosure of the cutting area and protecting the operator and the working environment.

[0038] For further details, please refer to [link / reference]. Figure 3The shielding structure 4 includes a dustproof box 41 installed on the outer surface of the vertical part of the T-shaped slider 32. The dustproof box 41 is U-shaped, and the inner walls on both sides are fixedly connected with shielding curtains 42. The shielding curtains 42 have good flexibility and sealing performance, and can closely fit the surface of the blank to form a closed space during the cutting process. Several connecting wheels 421 are arranged in an array at the ends of the two shielding curtains 42 on the same side that are close to each other. The connecting wheels 421 can reduce the frictional resistance of the shielding curtains 42 during deformation and movement, so that the shielding curtains 42 can cover the blank more smoothly. The inner side of the dustproof box 41 is symmetrically provided with support components 43 that are slidably connected to the outer surface of the adjacent connecting wheels 421. The support components 43 can not only provide support for the shielding curtains 42, but also drive the shielding curtains 42 to achieve precise deformation through their own movement, ensuring all-round coverage of the blank cutting part.

[0039] For further details, please refer to [link / reference]. Figure 4 The support component 43 includes a sliding rod 432. The lower end of the sliding rod 432 extends through the upper end of the dustproof box 41 and into the inner cavity of the dustproof box 41. The sliding rod 432 can slide up and down within the dustproof box 41, providing a basis for the subsequent movement of the curtain 42. A tension spring 431 for resetting the sliding rod 432 is sleeved on the outer surface of the upper end of the dustproof box 41. The tension force generated by the tension spring 431 makes the sliding rod 432 always have a downward tendency, thereby ensuring that the arc plate 434 is tightly attached to the surface of the blank and ensuring a sealing effect. The outer surface of the sliding rod 432 is symmetrically provided with connecting grooves 433 that slide and connect with the outer surface of the adjacent connecting wheel 421. The connecting grooves 433 provide a stable sliding track for the connecting wheel 421, allowing the connecting wheel 421 to slide along the surface of the dustproof box 41. The sliding rod 432 moves precisely as it moves. The lower end of the sliding rod 432 is fixedly connected to an arc-shaped plate 434 for pressing the surface of the blank. The arc design of the arc plate 434 can better fit the outer surface of the blank and enhance the sealing performance. When the dust box 41 moves downward with the T-shaped slider 32 until the arc plate 434 contacts the surface of the blank, as the T-shaped slider 32 continues to move downward, the dust box 41 moves downward relative to the sliding rod 432, and the sliding rod 432 moves upward relative to the dust box 41. During the upward movement, the sliding rod 432 stretches the tension spring 431. At the same time, the sliding rod 432 drives the connecting wheel 421 to move through the connecting groove 433. The connecting wheel 421 then pulls the shielding curtain 42 to generate displacement so that it covers the surface of the blank, achieving complete sealing of the cutting area.

[0040] In Example 3, based on Example 2, power transmission is achieved through the cooperation of the transmission component 52 and the cooperating connecting rod 51 in the positioning and clamping structure 5. The cooperation of the push rod 521, piston rod 523 and buffer spring 522 in the transmission component 52 prevents the billet from being subjected to excessive impact. The cooperation of the base plate 541 and clamping arm 542 in the clamping component 54 clamps the billet. The cooperation of the gear 5444, rack 5445 and roller 5442 in the drive component 544 enables relative movement of the clamping arm 542. The cooperation of the support wheel 5433, spring and telescopic rod 5434 in the buffer component 543 buffers and reduces shock, ultimately achieving stable clamping of the billet and ensuring cutting accuracy.

[0041] For further details, please refer to [link / reference]. Figure 5 The positioning and clamping structure 5 includes a transmission assembly 52 slidably mounted on the upper end of the cutting table 1. The transmission assembly 52 can transmit the power of the T-shaped slider 32 to the wedge plate 53, realizing the effective transmission and conversion of power. A clamping assembly 54 for clamping the blank is provided on one side of the upper end of the cutting table 1. The clamping assembly 54 is a component that directly clamps and fixes the blank, ensuring that the blank remains stable during the cutting process. The side of the transmission assembly 52 near the T-shaped slider 32 is rotatably connected to a cooperating element that is rotatably connected to the lower end of the horizontal part of the T-shaped slider 32. Link 51, also known as connecting rod 51, connects the T-shaped slider 32 and the transmission component 52. It converts the up-and-down movement of the T-shaped slider 32 into the horizontal movement of the transmission component 52, thus achieving coordinated action between the cutting structure 3 and the positioning and clamping structure 5. A wedge plate 53 that drives the clamping component 54 is fixedly connected to the side of the transmission component 52 away from the transmission component 52. The wedge plate 53, through its inclined surface structure, converts the horizontal thrust of the transmission component 52 into the clamping force of the clamping component 54, thereby clamping the blank.

[0042] For further details, please refer to [link / reference]. Figure 6The transmission assembly 52 includes a push rod 521 slidably connected to the upper end of the cutting table 1. The push rod 521 can slide horizontally on the cutting table 1 and is one of the main components for transmitting power. The upper end of the push rod 521 is rotatably connected to the cooperating link 51. This rotatable connection ensures that the cooperating link 51 will not jam when it drives the push rod 521 to move, thus ensuring smooth power transmission. A piston rod 523 is fixedly connected to the end of the transmission assembly 52 away from the cooperating link 51. The piston rod 523 can move together with the push rod 521 and transmit power to the wedge plate 53. A connecting rod slidably connected to the upper end of the cutting table 1 is slidably connected to the outer surface of the piston rod 523. 524. The connecting rod 524 provides guidance for the movement of the piston rod 523, ensuring that the piston rod 523 moves stably in the horizontal direction. The ends of the connecting rod 524 and the push rod 521 that are close to each other are fixedly connected to a buffer spring 522 sleeved on the outer surface of the piston rod 523. The buffer spring 522 can play a buffering role, preventing the push rod 521 from moving too fast and causing the clamping assembly 54 to generate too large instantaneous impact force on the blank, thus protecting the blank from damage. The end of the piston rod 523 away from the push rod 521 is fixedly connected to the wedge plate 53, so that the piston rod 523 can directly drive the wedge plate 53 to move, providing power for the action of the clamping assembly 54.

[0043] For further details, please refer to [link / reference]. Figure 7 and Figure 8 The clamping assembly 54 includes a base plate 541 fixedly mounted on the upper end of the cutting table 1. The base plate 541 provides a stable mounting foundation for other components of the clamping assembly 54, ensuring that each component can work in an orderly manner. A buffer component 543 supporting the billet is provided in the middle of the upper end of the base plate 541. The buffer component 543 supports the billet and also provides a buffering and shock-absorbing effect during clamping to prevent the billet from deforming. Clamping arms 542 are symmetrically slidably connected to the upper end of the base plate 541. The clamping arms 542 are components that directly contact the billet and apply clamping force. The clamping of the billet is achieved through relative movement. When released, spring limit rods 545 are symmetrically arranged on the upper left and right sides of the base plate 541 to limit the sliding trajectory of the clamping arms 542. The spring limit rods 545 can limit the sliding trajectory of the clamping arms 542, ensuring that the clamping arms 542 always move in the preset direction, avoiding the clamping arms 542 from deviating and affecting the clamping accuracy. At the same time, the spring structure can also provide assistance when the clamping arms 542 are reset. The inner cavity of the base plate 541 is provided with a drive assembly 544 that is driven by the wedge plate 53 to drive the clamping arms 542 on both sides to slide. The drive assembly 544 can convert the movement of the wedge plate 53 into the relative sliding of the clamping arms 542, realizing the clamping action.

[0044] For further details, please refer to [link / reference]. Figure 8 and Figure 9The drive assembly 544 includes a gear 5444 rotatably connected to the inner surface of the base plate 541. The gear 5444 plays a key role in power conversion and transmission, converting the movement of one rack into the reverse movement of another rack. The upper and lower parts of the outer surface of the gear 5444 are respectively meshed with racks 5445. Racks 5445 can move linearly under the drive of the gear 5444. The two racks 5445 are respectively fixedly connected to the inner wall of the adjacent clamping arms 542, so that the movement of racks 5445 can directly drive the movement of clamping arms 542. The lower rack 5445 near the wedge plate 53 is fixedly connected to a hollow rod 5441 sleeved on the outer surface of the wedge plate 53. The hollow rod 5441 can follow the wedge shape. The movement of plate 53 causes the lower rack 5445 to move. The inner wall of hollow rod 5441 is rotatably connected to roller 5442, which is in close contact with the inclined part of wedge plate 53. Roller 5442 can convert the sliding friction between hollow rod 5441 and wedge plate 53 into rolling friction, reducing frictional resistance and allowing wedge plate 53 to push hollow rod 5441 to move more smoothly. When hollow rod 5441 moves under the action of wedge plate 53, lower rack 5445 moves accordingly and drives gear 5444 to rotate. Gear 5444 rotates and drives upper rack 5445 to move in the opposite direction. The two racks 5445 drive the clamping arms 542 on both sides to generate relative displacement, thereby clamping the billet.

[0045] For further details, please refer to [link / reference]. Figure 10 The buffer component 543 includes a rectangular platform 5431 mounted on the upper center of the base plate 541. The rectangular platform 5431 provides a mounting carrier for other components of the buffer component 543, ensuring the stability of each component. The upper end of the rectangular platform 5431 is symmetrically provided with sliding grooves 5432, which provide tracks for the sliding of the support wheels 5433, ensuring that the support wheels 5433 can move in a preset direction. The inner surfaces of the two sliding grooves 5432 are slidably connected by springs to support wheels 5433 for abutting the blank. The blank is placed on the support wheels 5433. When the clamping arm 542 applies a clamping force to the blank, the support wheels 5433 will slide on the support wheels 5433. The spring inside the groove 5432 slides and compresses, and the spring can play a buffering and shock-absorbing role, reducing the impact of clamping force on the billet. The bottom wall of the inner cavity of both grooves 5432 is fixedly connected to the telescopic rod 5434. The inner cavity of the telescopic rod 5434 is filled with non-Newtonian fluid, and its movable rod abuts against the lower part of the outer surface of the support wheel 5433. The non-Newtonian fluid has the characteristic of hardening rapidly when subjected to external force impact, which can further enhance the support stability of the billet and prevent the billet from deforming during clamping. At the same time, the telescopic rod 5434 can also guide the movement of the support wheel 5433, ensuring that the support wheel 5433 moves smoothly.
