Description

Technical Field

[0001] The invention relates to the technical field of reciprocating oscillation, in particular to a reciprocating oscillation device driven by a linear servo motor. Background Art

[0002] Existing machine tools use oscillation devices to drive the processing parts to move during the processing, so as to perform auxiliary processing operations. Most of the existing reciprocating oscillation devices are driven by ball screws, but have certain defects in movement speed and positioning accuracy; therefore, the existing reciprocating oscillation devices are coordinated with linear motors, motion controllers, etc. to perform movement control, which has advantages in movement speed and positioning accuracy; and, due to less mechanical contact, linear motors have high responsiveness and long-term stability.

[0003] However, the existing oscillation device driven by a linear motor still has certain defects during use. Since it is driven by a linear motor, when the slide on the oscillation device needs to be stationary or stop running, it cannot be automatically locked, resulting in poor stability of the slide; when there is a sudden power outage, the linear motor is in a power-off state, and the slide is in a free state. Once there is external shaking or external impact, the slide will move, especially when the oscillation device is installed in a vertical state to move the slide up and down. At this time, even if there is no external force pushing, the slide and components will still move downward under the action of gravity of the slide and components, causing collisions between components, resulting in damage to the components. Severe cases will directly cause damage to the components, which is not conducive to actual use. Summary of the invention

[0011] As a further solution of the present invention, a protrusion block is symmetrically arranged on one side of the fixing seat close to the base, and the end of the protrusion block is fixedly connected to the base.

[0015] The beneficial effects of the present invention are: 1. During operation, the first slide is driven by the linear motor to slide back and forth. When the processing component is installed on the first slide, the first slide drives the processing component to move back and forth for processing; when the processing component is installed on the second slide, the linear motor installed on the base and the linear motor installed on the bracket cooperate to drive the first slide and the second slide to move back and forth respectively, so that they can move in multiple directions, thereby realizing oscillation operation, so that the processing component can perform multi-directional operations.

[0016] 2. When the first slide is required to be stationary, the piston rod of the electric telescopic rod is extended outward, so that the moving block drives the power-off locking mechanism to approach the rotating crown gear, so that the self-locking crown gear in the power-off locking mechanism is engaged with the rotating crown gear, and the rotating crown gear is locked, so that the rotating crown gear cannot rotate, thereby making the first slide unable to move, completing the self-locking of the first slide.

[0017] 3. When the first slide needs to move, the piston rod of the electric telescopic rod only needs to be retracted inward, and the reciprocating guide block drives the moving block to move inward. The moving block drives the self-locking crown gear in the power-off locking mechanism away from the rotating crown gear, thereby releasing the lock on the rotating crown gear. At this time, the transmission mechanism can rotate freely, thereby allowing the first slide to slide and releasing the self-locking of the first slide.

[0018] 4. When power failure occurs during the operation of the oscillation device, the electromagnet is in a power-off state, and the electromagnet releases its adsorption on the magnetic cylinder. Under the action of the elastic force of the self-locking spring, the regular polygonal sleeve drives the magnetic cylinder to move outward, and the magnetic cylinder drives the self-locking crown gear to move outward along the regular polygonal groove, so that the self-locking crown gear is engaged with the rotating crown gear, thereby locking the rotating crown gear; through the power-off locking mechanism set up, even in the case of power failure, the power-off self-locking mechanism can also lock the rotating crown gear, thereby making the first slide unable to move, preventing the first slide from shaking or moving in the case of power failure, causing collision damage between components.

[0027] As needed, a bracket 3 and a second slide 32 can be set on the first slide 12. The moving trajectory of the second slide 32 is perpendicular to the moving trajectory of the first slide 12. The bracket 3 and the second slide 32 are connected by a linear motor 2. The linear motor 2 is installed on the bracket 3. The mover seat 22 in the linear motor 2 is connected to the second slide 32, and the second slide 32 is driven to reciprocate through the mover seat 22.

[0028] See also Figures 4 to 6 The transmission mechanism includes a side support plate 4 fixedly connected to the side of the base 1, and the side of the side support plate 4 is rotatably connected with a first circular shaft 41 and a second circular shaft 42 in sequence through bearings. The other ends of the first circular shaft 41 and the second circular shaft 42 are rotatably connected to the raised portion of the side of the base 1 through bearings. A transmission gear 43 is fixedly sleeved on the first circular shaft 41, and an acceleration gear 44 is fixedly sleeved on the second circular shaft 42. One end of the second circular shaft 42 passes through the side support plate 4 and is fixedly sleeved with a rotating crown gear 45. The side of the rotating crown gear 45 with teeth is close to the fixed seat 5. A rack plate 46 is meshed above the transmission gear 43, and a plurality of T-shaped frames 47 are equidistantly fixedly connected to the upper end of the rack plate 46. The T-shaped frame 47 is fixedly connected to the lower end of the first slide 12 by bolts.

[0029] The transmission gear 43 is meshed with the acceleration gear 44 . The transmission gear 43 and the acceleration gear 44 are both arranged between the side support plate 4 and the protruding portion. The rotating crown gear 45 is rotationally connected to the side support plate 4 through the second circular shaft 42 .

[0030] The diameter of the transmission gear 43 is greater than the diameter of the acceleration gear 44, and the number of teeth of the transmission gear 43 is greater than the number of teeth of the acceleration gear 44; When the first slide 12 slides back and forth, the first slide 12 drives the rack plate 46 to move through the T-shaped frame 47. The rack plate 46 drives the transmission gear 43 to rotate during the reciprocating movement. When the transmission gear 43 rotates, it drives the acceleration gear 44 to accelerate the rotation. The acceleration gear 44 drives the rotating crown gear 45 to rotate synchronously through the second circular shaft 42.

[0031] See also Figure 4 , Figure 5 and Figure 7 A protruding block is symmetrically arranged on one side of the fixing seat 5 close to the base 1, and the end of the protruding block is fixedly connected to the base 1. A contraction groove 51 is opened on one side of the fixing seat 5 close to the base 1, and a groove 52 is symmetrically opened on the inner side of the contraction groove 51; The self-locking mechanism includes a moving block 6 slidably installed in the contraction groove 51, and a power-off locking mechanism is installed in the moving block 6. A reciprocating guide block 64 is symmetrically fixedly connected to the outer side of the moving block 6, and the inner side of the reciprocating guide block 64 is fixedly connected to the end of the piston rod of the electric telescopic rod 65.

[0032] The reciprocating guide block 64 is slidably connected to the groove 52 , and the electric telescopic rod 65 is fixedly mounted on the fixing seat 5 .

[0033] The piston rod of the electric telescopic rod 65 is extended and retracted to drive the reciprocating guide block 64 to slide back and forth along the groove 52, and the reciprocating guide block 64 drives the moving block 6 to slide back and forth along the contraction groove 51, and the moving block 6 drives the power-off locking mechanism to move back and forth; When the piston rod of the electric telescopic rod 65 extends outward, the reciprocating guide block 64 drives the moving block 6 to move outward along the contraction groove 51, and the moving block 6 drives the power-off locking mechanism to approach the rotating crown gear 45, thereby locking the rotating crown gear 45, so that the rotating crown gear 45 cannot rotate. Since the second circular shaft 42 is fixedly connected to the acceleration gear 44 and the rotating crown gear 45 respectively, when the rotating crown gear 45 cannot rotate, the second circular shaft 42 and the acceleration gear 44 are also unable to rotate; When the acceleration gear 44 cannot rotate, the transmission gear 43 cannot rotate either. When the transmission gear 43 cannot rotate, since the transmission gear 43 is meshed with the rack plate 46, the rack plate 46 cannot move. When the rack plate 46 cannot move, the T-frame 47 and the first slide 12 cannot move, completing the self-locking of the first slide 12, so that the first slide 12 is in a fixed state.

[0034] When the piston rod of the electric telescopic rod 65 contracts inward, the reciprocating guide block 64 drives the moving block 6 to move inward along the contraction groove 51, and the moving block 6 drives the power-off locking mechanism away from the rotating crown gear 45, thereby releasing the lock on the rotating crown gear 45. At this time, the transmission mechanism can rotate freely, thereby allowing the first slide 12 to slide, releasing the self-locking of the first slide 12.

[0035] See also Figure 5 , Figure 7 and Figure 8 A regular polygonal groove 61 is formed at one end of the moving block 6 close to the base 1, a circular groove 62 is formed from the innermost side of the regular polygonal groove 61 to the outside, and a limiting groove 63 is formed symmetrically on the inner side of the circular groove 62; The power-off locking mechanism includes a magnetic cylinder 7 inserted into the regular polygonal groove 61, one end of the magnetic cylinder 7 extends into the circular groove 62, and the magnetic cylinder 7 is slidably connected to the circular groove 62, one end of the magnetic cylinder 7 in the circular groove 62 is symmetrically fixedly connected to the limiting block 74, and the end of the magnetic cylinder 7 away from the limiting block 74 is fixedly connected to the self-locking crown gear 72, and the self-locking crown gear 72 is clamped with the rotating crown gear 45. The structure of the self-locking crown gear 72 is similar to that of the rotating crown gear 45, both of which have a plurality of teeth distributed in a circular array on one side of a circular block, and the teeth are integrally formed with the circular block, and the difference is that a circular hole is opened through the side of the rotating crown gear 45; A regular polygonal sleeve 71 and a self-locking spring 73 are sleeved on one side of the magnetic cylinder 7. The regular polygonal sleeve 71 is fixedly connected to the magnetic cylinder 7. The two ends of the self-locking spring 73 are respectively in contact with the regular polygonal sleeve 71 and the regular polygonal groove 61. The self-locking spring 73 applies elastic force to the regular polygonal sleeve 71. An electromagnet 8 is fixedly installed at the outermost end of the circular groove 62. The electromagnet 8 and the magnetic cylinder 7 are adsorbed and connected to each other.

[0036] The regular polygonal sleeve 71 is slidably connected to the regular polygonal groove 61 , the limiting block 74 is slidably connected to the limiting groove 63 , and the limiting groove 63 is not directly connected to the regular polygonal groove 61 , and the self-locking spring 73 is in a compressed state.

[0037] During normal operation, the electromagnet 8 is always powered on, and the electromagnet 8 firmly adsorbs the magnetic cylinder 7; When the moving block 6 moves outward, the moving block 6 drives the power-off locking mechanism to move outward. At this time, the self-locking crown gear 72 in the power-off locking mechanism engages with the rotating crown gear 45, thereby locking the rotating crown gear 45. When the moving block 6 moves inward, the moving block 6 drives the power-off locking mechanism to move inward, and at this time the self-locking crown gear 72 in the power-off locking mechanism is separated from the rotating crown gear 45, thereby releasing the locking of the rotating crown gear 45; When power is lost during the operation of the oscillation device, the electric telescopic rod 65 cannot work normally. At the same time, the electromagnet 8 is in a power-off state, thereby releasing the adsorption of the magnetic cylinder 7. Under the action of the elastic force of the self-locking spring 73, the regular polygonal sleeve 71 slides outward along the regular polygonal groove 61. The regular polygonal sleeve 71 drives the magnetic cylinder 7 to move outward. When the magnetic cylinder 7 moves, it drives the limit block 74 to slide along the limit groove 63. The movement range of the magnetic cylinder 7 is limited by the cooperation of the set limit block 74 and the limit groove 63. When the electromagnet 8 is energized, the electromagnet 8 can quickly adsorb the magnetic cylinder 7. When the magnetic cylinder 7 moves outward, it drives the self-locking crown gear 72 to move outward along the regular polygonal groove 61, so that the self-locking crown gear 72 engages with the rotating crown gear 45, thereby locking the rotating crown gear 45; By setting up the power-off locking mechanism, even in the case of power failure, the power-off self-locking mechanism can also lock the rotating crown gear 45, thereby making the first slide 12 unable to move, thereby preventing the first slide 12 from shaking or moving in the case of power failure, causing collision damage between components.

[0038] As required, the upper rack plate 46 can be installed at the lower end of the second slide 32 in the above manner, and the transmission mechanism, self-locking mechanism, and power-off locking mechanism can be installed on the bracket 3, so that the second slide 32 can be self-locked.

[0039] Working principle: When working, the linear motor 2 drives the first slide 12 to slide back and forth. When the processing part is installed on the first slide 12, the first slide 12 drives the processing part to move back and forth to perform processing operations; When the processing component is installed on the second slide 32, the linear motor 2 installed on the base 1 drives the first slide 12 to slide back and forth, the first slide 12 drives the bracket 3 to move synchronously, and the bracket 3 drives the second slide 32 to move; at this time, the second slide 32 is further driven by the linear motor 2 installed on the bracket 3 to move back and forth, and the processing component is driven to move back and forth by the second slide 32, so as to perform processing operations, and the linear motor 2 set on the base 1 cooperates with the linear motor 2 installed on the bracket 3, so that it can move in multiple directions, thereby realizing oscillation operation, so that the processing component can perform multi-directional operations.

[0040] When the first slide 12 moves, the rack plate 46 is driven to move through the T-frame 47. The rack plate 46 drives the transmission gear 43 to rotate during the reciprocating movement. When the transmission gear 43 rotates, it drives the acceleration gear 44 to accelerate the rotation. The acceleration gear 44 drives the rotating crown gear 45 to rotate synchronously through the second circular shaft 42. Therefore, when the rotating crown gear 45 is locked and cannot rotate, the first slide 12 cannot move.

[0041] When the first slide 12 is required to be stationary and cannot be moved, the piston rod of the electric telescopic rod 65 is extended outward, so that the reciprocating guide block 64 drives the moving block 6 to move outward, and the moving block 6 drives the power-off locking mechanism to approach the rotating crown gear 45, so that the self-locking crown gear 72 in the power-off locking mechanism is engaged with the rotating crown gear 45, and the rotating crown gear 45 is locked, so that the rotating crown gear 45 cannot rotate, so that the first slide 12 cannot move, and the self-locking of the first slide 12 is completed. At this time, the first slide 12 is in a state of being completely unable to move, and the stability is relatively high; When the first slide 12 needs to move, it only needs to retract the piston rod of the electric telescopic rod 65 inward, and the reciprocating guide block 64 drives the moving block 6 to move inward. The moving block 6 drives the self-locking crown gear 72 in the power-off locking mechanism away from the rotating crown gear 45, thereby releasing the lock on the rotating crown gear 45. At this time, the transmission mechanism can rotate freely, thereby allowing the first slide 12 to slide, releasing the self-locking of the first slide 12.

[0042] When power is lost during the operation of the oscillating device, the electric telescopic rod 65 cannot be normally extended and retracted. At the same time, the electromagnet 8 is in a power-off state. The electromagnet 8 releases the adsorption of the magnetic cylinder 7. Under the elastic force of the self-locking spring 73, the regular polygonal sleeve 71 slides outward along the regular polygonal groove 61. The regular polygonal sleeve 71 drives the magnetic cylinder 7 to move outward. The magnetic cylinder 7 drives the self-locking crown gear 72 to move outward along the regular polygonal groove 61, so that the self-locking crown gear 72 is engaged with the rotating crown gear 45, thereby locking the rotating crown gear 45. By setting up the power-off locking mechanism, even in the case of power failure, the power-off self-locking mechanism can also lock the rotating crown gear 45, thereby making the first slide 12 unable to move, thereby preventing the first slide 12 from shaking or moving in the case of power failure, causing collision damage between components.
