Description

Technical Field

[0001] The utility model discloses a clamping jaw mechanism, belongs to the technical field of clamping jaw devices, and specifically relates to an electric gear rack centering clamping jaw mechanism. Background Art

[0002] Bottle cap gripper mechanism is a kind of equipment usually used in automated production lines to grab, tighten or unfasten bottle caps. This mechanism usually includes some grippers or fixtures, and the movement of the grippers is controlled by pneumatic, hydraulic or electric systems. In automated production lines, bottle cap gripper mechanisms can be used to quickly and accurately handle a large number of bottle caps, improving production efficiency and quality.

[0003] The design and use of the bottle cap gripper mechanism needs to take into account factors such as the speed of the production line, the characteristics of the bottle cap, the accuracy requirements of the operation, and safety to ensure the smooth progress of the entire production process.

[0004] The bottle cap clamping mechanism in the prior art is mostly driven directly by a cylinder, and the clamping jaws are opened and closed by using an opening and closing cylinder to clamp the bottle cap. However, in this way, one cylinder can only clamp one bottle cap, which is extremely inefficient. Moreover, when a cylinder fails, it will cause errors in the entire production line.

As the motor 2 rotates, the bidirectional screw 11 is driven to rotate to drive the first linear bearing 12 and the second linear bearing 13 to move in relative directions.

[0027] In one embodiment, Figures 1 to 4 As shown, the centering jaw assembly 4 includes: a first centering plate 14, a second centering plate 15, a third centering plate 16 and a fourth centering plate 17, which are sequentially mounted on the first slide bar 8 and the second slide bar 9, and both ends of each centering plate are slidably mounted on the first slide bar 8 and the second slide bar 9 through a sliding sleeve; each centering plate is provided with a plurality of equidistantly arranged jaws 10; the first centering plate 14 is sleeved on the first linear bearing 12 to move with the first linear bearing 12, and the fourth centering plate 17 is sleeved on the second linear bearing 13 to move with the second linear bearing 13.

[0031] Working principle: When the utility model is working, the motor 2 works first, and as the motor 2 rotates, the bidirectional screw 11 in the driving assembly 3 is driven to rotate through the coupling. As the bidirectional screw 11 rotates, the first linear bearing 12 and the second linear bearing 13 are driven to work simultaneously and make opposite reverse movements (the first linear bearing 12 moves to the left, and the second linear bearing 13 moves to the right). As the first linear bearing 12 and the second linear bearing 13 move, the first centering plate 14 and the fourth centering plate 17 are driven to move simultaneously. At the same time, the first centering plate 14 drives the third centering plate 16 to move in the same direction through the first connecting plate 18, and the fourth centering plate 17 drives the second centering plate 15 to move in the same direction through the second connecting plate 19, so that the first centering plate 14 is centered with the second centering plate 15, and the third centering plate 16 is centered with the fourth centering plate 17. When the clamp 10 touches the bottle cap, the pressure is reduced by the spring 21 to complete the clamping work.
