Fig. 1 to 5 show a thimble moving structure according to the present invention, which includes a base 10, a driving member 20, a lead screw 30, a sliding assembly 40, an actuator 50, a thimble 60, an elastic member 70, a roller 80, and an anti-rotation assembly 90.

The base 10 includes a first board 11, a second board 12, a first slide rail 13 and a second slide rail 14. The second plate 12 extends from the end of the first plate 11 and is perpendicular to the first plate 11. The first slide rail 13 and the second slide rail 14 are disposed on the first plate 11. The first slide rail 13 extends transversely, the second slide rail 14 extends vertically, and the extending direction of the second slide rail 14 is perpendicular to the second plate body 12.

The drive member 20 is a motor. The driving member 20 is fixed to the first plate 11 of the base 10. The spindle 30 is connected to the output of the drive element 20.

The slide assembly 40 includes a connecting plate 41, a slide plate 42, and a contact block 43. The connecting plate 41 and the contact block 43 are fixed to the slide plate 42. The connecting plate 41 is perpendicular to the slide plate 42. The extending direction of the contact block 43 is the same as the extending direction of the slide plate 42. The contact block 43 is provided with a bevel 430. The connecting plate 41 is engaged with the lead screw 30. The sliding plate 42 cooperates with the first sliding rail 13 to slidably mount the sliding assembly 40 to the base 10. The sliding assembly 40 is laterally oriented (parallel to the horizontal) relative to the direction of movement of the base 10.

The actuator 50 includes a slider 51, an actuator block 52, and an actuator cam 53. The transmission block 52 is fixed to the slider 51. The driving cam 53 is rotatably mounted to the bottom of the driving block 52. The slider 51 cooperates with the second slide 14 to slidably mount the actuator 50 to the base 10. The direction of movement of the actuator 50 relative to the base 10 is vertical (perpendicular to the horizontal). The interference of the drive cam 53 with the ramp 430 of the slide assembly 40 causes the driver 50 to make rolling contact with the slide assembly 40.

The ejector pin 60 is mounted to the second plate 12 of the base 10. The bearing is installed between the thimble 60 and the second plate 12 to reduce friction between the thimble 60 and the second plate 12. The bearing is a linear bearing.

The elastic member 70 is a spring. The elastic element 70 is sleeved on the thimble 60, and two ends of the elastic element respectively abut against the thimble 60 and the second plate 12 of the base 10, so that the roller 80 on the thimble 60 is kept in close contact with the driver 50.

The rotation preventing assembly 90 includes a rotation preventing shaft 91 and a stopper 92. The rotation preventing shaft 91 is fixed to the second plate 12, and the stopper 92 is fixed to the thimble 60. The limiting block 92 is provided with a limiting groove 920, and the rotation preventing shaft 91 is located in the limiting groove 920. In other embodiments, the rotation-preventing shaft 91 is fixed to the thimble 60, the limiting block 92 is fixed to the second plate 12, and the rotation-preventing shaft 91 is located in the limiting groove 920, so as to achieve the rotation-preventing effect.

The roller 80 is rotatably mounted at the end of the thimble 60, and the roller 80 abuts against the transmission block 52 of the transmission 50, so that the thimble 60 is in rolling contact with the transmission 50. The elastic member 70 keeps the roller 80 of the thimble 60 in close contact with the actuator 50.

When the thimble moving structure is used, the driving member 20 drives the screw rod 30 to rotate, the screw rod 30 drives the sliding assembly 40 to move transversely, the inclined surface 430 of the sliding assembly 40 abuts against the transmission cam 53 of the actuator 50, the actuator 50 vertically slides relative to the base 10, and the transmission block 52 abuts against the roller 80, so that the thimble 60 moves up and down. During the up-and-down movement of the thimble 60, the stopper 92 moves along the rotation-preventing shaft 91. When the thimble 60 rotates, the edge of the limiting groove 920 is abutted against the rotation-preventing shaft 91, so that the limiting block 92 cannot rotate, the thimble 60 does not rotate, and the rotation-preventing effect is achieved.

Through the design, the screw rod 30 is adopted for driving, so that the movement control precision is high; the screw rod 30 and the sliding assembly 40 are designed to be perpendicular to the thimble 60 (i.e. arranged horizontally), and the vertical direction occupies a small space.

The above examples only show some embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, variations and modifications can be made without departing from the spirit of the invention, and all equivalent modifications and changes can be made to the above embodiments according to the essential technology of the invention, which falls into the protection scope of the invention.
