Description

Technical Field

[0001] The present invention relates to the technical field of ball screw processing, in particular to a blank cutting device for ball screw processing. Background Art

[0002] Most existing cutting equipment lacks an effective clamping mechanism for ball screws. When cutting ball screw blanks, the lack of a secure clamping mechanism causes the blank to shift, wobble, or even vibrate under the cutting force. For example, during high-speed cutting, if the blank is not securely fixed, the reaction force generated by the cutting tool acting on the blank can cause the blank to shift, ultimately resulting in deviations in the cut dimensions and making it difficult to achieve high-precision machining requirements.

All the crescent plates are provided with an adapter shaft, one of the crescent plates is connected to the support plate, and the other crescent plate is connected to the second clamp.

[0008] Preferably, a force-bearing plate is provided at one end of the lower moving plate, and the size of the force-bearing plate matches that of the stop seat. A connecting shaft for connecting to a crescent plate is provided at the other end of the lower moving plate. A first limiting groove is also provided on the lower moving plate, and a limiting block is inserted in the first limiting groove to limit the movement of the lower moving plate.

[0009] Preferably, a connecting hole is provided at one end of the crescent plate, and the connecting hole is sleeved on the connecting shaft to connect and rotate the crescent plate and the lower plate, and an adaptor shaft is connected to the other end of the crescent plate, and a support rod is connected to the adaptor shaft, and a slide groove is provided on the crescent plate, and a second limiting groove is provided on the support rod, and a lower hook shaft is inserted into the slide groove, and the lower hook shaft is provided on the lower hook plate, and a limiting shaft is clamped on the second limiting groove, and the limiting shaft is provided on the supporting structure.

[0010] Preferably, the support rod supports the second clamp and the support plate respectively, the crescent plate and the support rod are at least a pair and are arranged in a mirror image, and the second clamp and the support plate move synchronously.

[0014] Preferably, a collecting plate is connected to the protective cover, the surface of the collecting plate is provided with an arc, the arc is consistent with the center of the cutting disk, a baffle is connected to the collecting plate, the collecting plate and the baffle form a receiving bin, and a receiving groove is provided in the receiving bin.

[0015] Preferably, the protective cover is further provided with a receiving rod, a telescopic rod is provided in the receiving rod, and a ball is provided at the sliding end of the telescopic rod;

[0016] A wave plate is further provided in the moving groove, and the wave plate is in contact with the ball.

[0017] Preferably, the supporting structure includes a fixing plate for supporting the lower hook plate and the limiting shaft, and a feeding roller for feeding is connected to the fixing plate.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: in the billet cutting device for ball screw processing, the hydraulic mechanism drives the movable plate to move downward, and the seat synchronously squeezes the lower plate of the force-bearing mechanism, and the limit block and the limit groove cooperate to guide. The lower plate drives the mirrored crescent plate to rotate through the connecting shaft, so that the second clamp on the support rod engages with the first clamp of the movable plate, forming an embracing clamp. At the same time, another set of crescent plates drives the support plate to move upward synchronously, symmetrically supporting the ball screw cutting position. This mechanical linkage integrates "clamping-support", completely solving the problems of billet displacement and vibration, and the cutting size deviation can be accurately controlled to meet the requirements of precision processing.

[0019] This blank cutting device for ball screw machining features a curved collection plate within a protective cover, coaxial with the cutting disc's center. Its curvature matches the cutting trajectory, allowing debris generated by high-speed cutting to fall tangentially into a collection chamber. A spiral guide structure within the collection chamber automatically collects debris at the discharge port, significantly improving chip collection efficiency compared to traditional open-type cutting. This design prevents debris accumulation from impacting equipment operation and eliminates the safety hazard of frequent manual cleaning, making it suitable for continuous operation on automated production lines.

[0020] This billet cutting device for ball screw machining utilizes independent hydraulic control circuits to achieve differentiated drive for the moving plate and cutting mechanism. While the first hydraulic rod drives the moving plate to clamp the billet, the second hydraulic rod simultaneously drives the cutting mechanism up and down within the moving groove, allowing precise control of the cutting depth by adjusting the hydraulic pressure. Compared to traditional single-hydraulic source equipment, this device offers higher resolution for cutting depth adjustment and infinitely variable speeds within a specified range, significantly enhancing its adaptability to machining ball screws of varying specifications, enabling switching between products without hardware replacement.

[0021] In this billet cutting device for ball screw machining, the telescopic rod of the protective cover closely engages the corrugated plate via the ball bearings during cutting mechanism movement, generating periodic wave damping feedback. This provides the operator with clear tactile feedback when adjusting the cutting mechanism's position, preventing cutting errors caused by excessive manual movement. This damping system improves cutting feed speed control accuracy, particularly when cutting thin-walled ball screws. It prevents tool chipping, extends tool life, and reduces machining costs.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See also Figures 1-10The present invention provides a technical solution: a blank cutting device for ball screw processing, comprising a top plate 1 and a support structure 6. When the device is in normal use, the support structure 6 is installed on the top floor of the factory building, so that it can carry the hydraulic mechanism 2, and the connection of the support structure 6 is stable. A hydraulic mechanism 2 is provided on the top plate 1, and the hydraulic mechanism 2 is mainly used to drive the movable plate 4 and the cutting mechanism 3 to move, and the hydraulic mechanism 2 controls the cutting mechanism 3 and the movable plate 4 respectively. In the case of no-load, the power driving the second diversion hydraulic valve 22 is greater than the power driving the first diversion hydraulic valve 21. During the use phase, the two first diversion hydraulics 21 output first, and after the two first diversion hydraulics 21 stop, the second diversion hydraulic 22 outputs, and further includes: a movable plate 4 connected to the hydraulic mechanism 2, the hydraulic mechanism 2 drives the movable plate 4 to move, and a bearing seat 42 is provided on the movable plate 4, and the bearing seat 42 is used to connect and support the first clamp 43, and the bearing seat 42 is connected to the first clamp 43, and the first clamp 43 can be buckled with the second clamp 532, so that the ball screw being cut can be fixed to prevent the ball screw from being offset during the cutting process. The movable plate 4 is also provided with a retaining seat 44, which is used to press down the force-bearing plate 511, thereby driving the lower plate 51 to move downward, to drive the force-bearing mechanism 5 to deform, and a force-bearing mechanism 5 is provided on the supporting structure 6, and the force-bearing mechanism 5 is squeezed and moved by the retaining seat 44, and the force-bearing mechanism 5 includes a lower plate 51, and at least two crescent plates 52 are connected to the lower plate 51. The specific number of the lower plates 51 is four, and each of the four lower plates 51 is provided with two crescent plates 52, one of the crescent plates 52 is provided with a second clamp 532, and the other crescent plate 52 is provided with a support plate 54.

[0035] See also Figure 6The top of the force-bearing plate 511 is provided with a force-bearing plate 511 at one end of the lower moving plate 51, and the size of the force-bearing plate 511 matches that of the retaining seat 44. The top of the force-bearing plate 511 is provided with rubber. The advantage of using rubber is that, first, it can achieve an anti-slip effect when the retaining seat 44 and the lower moving plate 51 are in contact, and prevent the retaining seat 44 from slipping when in contact with the lower moving plate 51. Second, it is to protect the lower moving plate 51 and prevent the retaining seat 44 and the lower moving plate 51 from making hard contact, which leads to wear of the retaining seat 44 and the lower moving plate 51. The other end of the lower plate 51 is provided with a connecting shaft 513 for connecting the crescent plate 52. The connecting shaft 513 is set at the bottom of the lower plate 51, which can allow the crescent plate 52 to move on the connecting shaft 513 When the lower plate 51 is rotated up and down, a first limit groove 512 is provided on the lower plate 51. The first limit groove 512 can ensure that the lower plate 51 is horizontal when sliding up and down on the connecting plate 32. A limit block 55 is inserted in the first limit groove 512 to limit the movement of the lower plate 51. The limit block 55 is used to connect the lower plate 51 and also allow the lower plate 51 to move up and down. When the lower plate 51 is squeezed by the support 44, the lower plate 51 will move downward under the limit of the limit block 55. At this time, one end of the crescent plate 52 connected to the connecting shaft 513 will be subjected to the downward force, and the position state of the crescent plate 52 will change.

[0036] See also Figure 7, a connecting hole 521 is provided at one end of the crescent plate 52, and the size of the connecting hole 521 matches the size of the connecting shaft 513. The function of the connecting hole 521 is to be sleeved with the connecting shaft 513 to ensure that the crescent plate 52 can rotate at the bottom end of the lower plate 51 at the end with the connecting hole 521. The connecting hole 521 is sleeved on the connecting shaft 513 to connect and rotate the crescent plate 52 and the lower plate 51. This design ensures that when the lower plate 51 is pressed down to drive the crescent plate 52 to move, the crescent plate 52 will rotate, and the other end of the crescent plate 52 is connected to an adapter shaft 523, which allows the support rod 53 to rotate at one end of the crescent plate 52. The adapter shaft 523 is connected to the support rod 53, which is used to support the second clamp 532 and the support plate 54, and can allow the second clamp 532 and the support plate 54 to maintain longitudinal up and down movement. A slide groove 522 is provided on the crescent plate 52, and the slide groove 522 is used to limit the lower hook shaft 561 on the lower hook plate 56. The lower hook shaft 561 is a fulcrum, and the crescent plate 52 is pressed downward when the lower plate 51 moves downward. The crescent plate 52 is affected by the lower hook shaft 561, and the end connected to the support rod 53 is tilted. The adapting shaft 523 adapts to the angle deviation of the crescent plate 52, and the second limiting groove 531 is longitudinally lifted, so that the second clamp 532 or the first hydraulic rod 24 connected to the second limiting groove 531 moves upward. The support rod 53 is provided with a second limiting The positioning groove 531 and the slide groove 522 are connected with a lower hook shaft 561. The slide groove 522 is affected by the fulcrum of the lower hook shaft 561. The lower hook shaft 561 is arranged on the lower hook plate 56. The lower hook plate 56 is used to connect the lower hook shaft 561 to the connecting plate 32. The second limiting groove 531 is clamped with a limiting shaft 57. The limiting shaft 57 is used to limit the support rod 53 so that the support rod 53 can be tightly attached to the inner side of the support structure 6 and the support rod 53 can move up and down. The limiting shaft 57 is arranged on the support structure 6.

[0037] See also Figure 8 The support rod 53 supports the second clamp 532 and the support plate 54 respectively. The crescent plate 52 and the support rod 53 are at least a pair. The second clamp 532 is fastened to the first clamp 43 to fix the ball screw. Figure 5When the second clamp 532 and the support plate 54 move down, the height is lower than the height of the feed roller 62, ensuring that the feed roller 62 will not generate friction with the ball screw when transporting the screw, affecting the efficiency of transporting the ball screw.

[0038] See also Figure 1 The hydraulic mechanism 2 includes a first flow diversion hydraulic machine 21 and a second flow diversion hydraulic machine 22 provided on the top plate 1. There are two first flow diversion hydraulic machines 21, which are respectively provided on both sides of the top plate 1. The two first flow diversion hydraulic machines 21 are connected through a diversion pipe 23 to ensure that the hydraulic pressure of the first flow diversion hydraulic machine 21 is consistent, so that the first hydraulic rod 24 can be controlled to move up and down at the same time, stably driving the movable plate 4 to move up and down. The first flow diversion hydraulic machine 21 is provided with a first hydraulic rod 24. The first flow diversion hydraulic machine 21 pushes the first hydraulic rod 24 to move the first hydraulic rod 24. The pressure rod 24 pushes the movable plate 4 to move downward until the lower plate 51 is pressed down to the displacement limit. The second diversion hydraulic machine 22 drives the second hydraulic rod 25 to drive the cutting mechanism 3 to move downward to cut the ball screw. The second diversion hydraulic machine 22 is provided with a second hydraulic rod 25. The first hydraulic rod 24 and the second hydraulic rod 25 are connected by a connecting flange 26. The first hydraulic rod 24 and the second hydraulic rod 25 are respectively connected to the movable plate 4 and the cutting mechanism 3. The first diversion hydraulic machine 21 and the second diversion hydraulic machine 22 are connected by a diversion pipe 23.

[0039] See also Figure 9 A moving groove 41 is provided on the moving plate 4, and the moving groove 41 is used to allow the cutting mechanism 3 to move up and down on the moving plate 4. The cutting mechanism 3 is placed in the moving groove 41, and the cutting mechanism 3 includes a connecting plate 32. The connecting plate 32 is used to carry the connecting flange 26 fixed to the second hydraulic rod 25, and a motor 31 is provided on the connecting plate 32. The motor 31 is used to drive the cutting disk 34 to rotate so as to cut the ball screw. A motor shaft 35 is provided on the motor 31, and a cutting disk 34 is connected to the motor shaft 35. A protective cover 33 is provided on the outside of the cutting disk 34. The protective cover 33 is arranged on the connecting plate 32 in the same manner as the motor 31. The protective cover 33 is used to prevent accidents when the cutting disk 34 rotates at high speed, thereby causing accidents.

[0040] The protective cover 33 is connected to a collecting plate 36, and the surface of the collecting plate 36 is provided with an arc, and the arc is consistent with the center of the cutting disc 34. The advantage of this design is that when the cutting disc 34 rotates to cut the ball screw, the generated debris will be driven by the cutting disc 34 and will enter the receiving bin 362 through the influence of the collecting plate 36. The collecting plate 36 is connected to the collecting plate 36, and the inner wall of the baffle 361 is used to prevent the debris from continuing to splash and allow the cut debris to enter the receiving bin 362. The collecting plate 36 and the baffle 361 form a receiving bin 362, and the receiving bin 362 is provided with a receiving groove 363. The receiving groove 363 is used to load the debris generated by the cutting disc 34. When it is finally discharged, it can be discharged uniformly, and the height of the collecting plate 36 and the cutting disc 34 is higher than the height of the cutting disc 34 and the top of the screw, thereby ensuring that the existence of the collecting plate 36 will not affect the work of the cutting disc 34 to completely cut off the screw.

[0041] See also Figure 10 The protective cover 33 is also provided with a accommodating rod 37, and a telescopic rod 371 is provided in the accommodating rod 37. The accommodating rod 37 is arranged on the outer shell of the accommodating rod 37, and a compression spring is provided on the inner side of the accommodating rod 37. The compression spring can push the telescopic rod 371 outward, and the sliding end of the telescopic rod 371 is provided with a ball 372. The ball 372 can roll in the telescopic rod 371 to reduce the friction between the wave plate 38. A wave plate 38 is also provided in the moving groove 41. The wave plate 38 and the ball 372 are in close contact. The wave plate 38 can allow the telescopic rod 371 to move back and forth. This design produces periodic fluctuation damping feedback to ensure that when the protective cover 33 moves downward, the second diversion hydraulic valve 22 can better drive and control the moving position of the protective cover 33.

[0042] See also Figure 5 The support structure 6 includes a fixed plate 61 for supporting the lower hook plate 56 and the limiting shaft 57. The fixed plate 61 is used to support the feed roller 62. The feed roller 62 for feeding is connected to the fixed plate 61. The feed roller 62 is used to transport the screw.

[0043] When the blank cutting device for ball screw processing is in use, the feed roller 62 on the fixed plate 61 of the support structure 6 first transports the ball screw blank to the processing position. At this time, the second clamp 532 and the support plate 54 press down the support rod 53 due to their own weight, causing the lower plate 51 to move upward. The height of the second clamp 532 and the support plate 54 is lower than the feed roller 62 to avoid interference. When the first stop 52 is stopped, the second stop 52 is stopped, and the second stop 52 is stopped, so that the second stop 52 is stopped, and the second stop 52 is stopped, so that the second stop 52 is stopped, and the second stop 52 is stopped, so that the second stop 52 is stopped, and the second stop 52 is stopped, so that the second stop 52 is stopped, and the second stop 52 is stopped, so that the second stop 52 is stopped, and the second stop 52 is stopped, so that the second stop 52 is stopped, and the second stop 52 is stopped, so that the second stop 52 is stopped, After clamping is complete, the second diverter hydraulic unit 22 of the hydraulic mechanism 2, via the second hydraulic rod 25, drives the cutting mechanism 3 downward along the movable groove 41 of the movable plate 4. The motor 31, via the motor shaft 35, drives the cutting disc 34 to rotate at high speed for cutting. A protective shield 33 protects the outer surface of the cutting disc 34. During the cutting process, a collection plate 36, coaxial with the center of the cutting disc 34, guides the debris along an arc into the receiving chamber 362 surrounded by baffles 361, where it is collected uniformly in the receiving groove 363. Simultaneously, a compression spring acts on the telescopic rod 371 within the receiving rod 37 of the protective shield 33, forcing the ball bearing 372 into close contact with the corrugated plate 38 of the movable groove 41. As the cutting mechanism 3 moves downward, the ball bearing 372 rolls along the corrugated plate 38, generating periodic damping feedback and assisting in precise control of the cutting depth. When the cutting is completed, the hydraulic mechanism 2 reverses and the movable plate 4 moves upward. The lower plate 51 loses the pressure of the support seat 44. The second clamp 532 and the support plate 54 press the support rod 53 downward due to their own weight, driving the crescent plate 52 to reset. The feed roller 62 can continue to transport the next section of the blank. The whole process is achieved through the diversion control of the hydraulic mechanism 2, the lever transmission of the force-bearing mechanism 5 and the cooperation of various limit structures to achieve stable clamping of the blank, precise cutting and debris collection.

[0044] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
