[0028] Reference Figures 1 to 7 A positioning and fastening device includes a fixed seat 10, a reducer assembly 20, a transmission kit 30 and a punching sliding assembly 40. The reducer assembly 20 is detachably arranged on the fixed seat 10. The transmission kit 30 is arranged on the fixed seat 10 and connected to the reducer assembly 20. The punching sliding assembly 40 is arranged on the fixed seat 10 and connected to the transmission kit 30. The punching sliding assembly 40 can reciprocate in the vertical direction under the drive of the reducer assembly 20. The pressing member 50 is used to press the punching sliding assembly 40 to prevent the punching sliding assembly 40 from loosening.

[0029] It can be understood that a pre-tightening force is applied to the punching slide assembly 40 by the clamping member 50, so that the punching slide assembly 40 always remains in a clamped state during punching, making the punching more stable and avoiding the situation where the adhesion of the small card after punching is unqualified.

[0030] Reference Figures 1 to 7 The transmission kit 30 includes a connecting sleeve 31 and an eccentric member 32. The connecting sleeve 31 is connected to the output end of the reducer assembly 20. The eccentric member 32 includes a concentric end 321 and an eccentric end 322. The concentric end 321 is inserted into the connecting sleeve 31. The eccentric end 322 is arranged at one end of the concentric end 321 and is opposite to the connecting sleeve 31. The axis of the eccentric end 322 is parallel to the axis of the connecting sleeve 31 and does not overlap.

[0031] It can be understood that the reducer assembly 20 drives the connecting sleeve 31 to rotate, the connecting sleeve 31 drives the concentric end 321 of the eccentric member 32 to rotate, and the eccentric end 322 eccentrically arranged at the end of the concentric end 321 rotates around the axis of the connecting sleeve 31 under the drive of the concentric end 321.

[0032] Reference Figures 1 to 5 The punching sliding assembly 40 includes a mounting plate 41, a first slide rail 42, a second slide rail 43 and a sliding plate 44. The mounting plate 41 is detachably arranged on the fixing seat 10. The connecting sleeve 31 is rotatably inserted into the mounting plate 41. The first slide rail 42 is arranged on the mounting plate 41. A first slide groove 421 is provided on the first slide rail 42. The second slide rail 43 is arranged on the mounting plate 41 and is opposite to the first slide rail 42. A second slide groove 431 is provided on the second slide rail 43. One side of the sliding plate 44 is accommodated in the first slide groove 421, and the other side is accommodated in the second slide groove 431. A notch 441 is provided on the sliding plate 44. The eccentric end 322 is inserted in the notch 441. The rotation of the eccentric end 322 can drive the sliding plate 44 to rise and fall.

[0033] It can be understood that the eccentric end 322 performs reciprocating motion in the slot 441 , and the sliding plate 44 performs lifting and reciprocating motion driven by the eccentric end 322 .

[0034] Reference Figure 5 The pressing member 50 is disposed on the mounting plate 41 and is in contact with the second slide rail 43. The pressing member 50 is provided with a first inclined surface 51. The second slide rail 43 is provided with a second inclined surface 432. The first inclined surface 51 and the second inclined surface 432 are in contact with each other. The pressing member 50 can apply a force to the second slide rail 43 toward the first slide rail 42.

[0035] It can be understood that in some embodiments of the present invention, the clamping member 50 is installed on the mounting plate 41 by fasteners, and a force away from the clamping member 50 is applied to the second slide rail 43 through the first inclined surface 51 and the second inclined surface 432, and the first slide rail 42 is fixedly connected to the mounting plate 41. In this way, under the action of the clamping member 50, the second slide rail 43 can cooperate with the first slide rail 42 to be close to the sliding plate 44 to avoid looseness.

[0036] Reference Figure 6 A bearing is provided on the eccentric end 322. The eccentric end 322 contacts the inner wall of the notch 441 through the bearing.

[0037] It is worth noting that the bearing can transform the sliding friction between the eccentric end 322 and the notch 441 into rolling friction, thereby reducing the friction loss between the two.

[0038] Reference Figure 5 The first slide groove 421 and the second slide groove 431 are both provided with an avoidance groove 421a.

[0039] It is worth noting that the avoidance groove 421a can effectively avoid the situation in which corner-to-corner machining errors are easily caused during machining, thereby reducing the difficulty of machining.

[0040] Reference Figure 6 A bearing is provided on the concentric end 321. The concentric end 321 is rotatably connected to the mounting plate 41 through the bearing.

[0041] It can be understood that the bearing can transform the sliding friction between the concentric end 321 and the mounting plate 41 into rolling friction, thereby reducing the friction loss between the two.
