Description

Technical Field

[0001] The utility model belongs to the technical field of material clamping, and in particular relates to a novel self-adaptive clamping claw with a built-in drive. Background Art

[0002] In modern industrial production, product variety is increasing, and workpieces come in a wide variety of shapes, sizes, and materials. For example, in electronic equipment manufacturing, various shapes of circuit boards, tiny electronic components, and housings of varying sizes must be handled. Traditional grippers with fixed sizes and shapes struggle to efficiently and precisely grasp these diverse workpieces. This is where adaptive grippers come in. They automatically adjust their gripping method based on the shape and size of the workpiece, improving production efficiency.

[0003] Most existing gripper transmission mechanisms use a cross roller cage in conjunction with gear racks and slide rails for transmission and limiting. However, this mechanism requires the use of a cross roller cage and a certain holding force. The cross roller cage requires a certain holding force, so this pin is needed to support the racks on both sides to allow the cross rollers to have a certain holding force, thereby using pins of different sizes to eliminate the shaking gap between the fingers.

[0004] However, the existing pin structure always needs to support the racks on both sides, so the existence of the pin greatly affects the opening and closing stroke of the clamp under the same volume, and the cost of using a cross roller cage to limit the position will also be very high.

DETAILED DESCRIPTION

[0022] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will provide a clear and complete description of the technical solutions of the present invention in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0023] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0024] Reference Figures 1 to 3 As shown, an embodiment of the utility model provides a new type of built-in driven adaptive clamp, including a main body shell 1, on which a main body upper end cover 2 and a main body lower end cover 3 are respectively provided, a motor slide rail connector 9 is provided in the main body shell 1, and the motor 11 is connected to one end of the motor slide rail connector 9, the main shaft of the motor 11 passes through the motor slide rail connector 9, and a gear 7 is provided on the main shaft of the motor 11, and a slide rail 8 is provided at the other end of the motor slide rail connector 9, two rack chucks 4 are provided in the slide rail 8, the two rack chucks 4 are meshed with the gear 7, and the rack chuck 4 slides on the main body lower end cover 3.

[0025] During use, the motor 11 drives the gear 7 to rotate, and the rotation of the gear 7 can drive the two rack clamps 4 to move toward or relative to each other in the slide rail 8, thereby realizing the clamping of the material, and greatly improving the opening and closing stroke of the clamping jaws under the same volume, making the drive built-in, and realizing the dial adjustment of torque and speed, without the need to connect to the host computer, and simple operation.

[0026] Specifically, two ball grooves 13 are provided on the rack chuck 4 , and an upper groove 14 and a lower groove 15 are provided in the slide rail 8 . A plurality of balls 6 are provided in both the upper groove 14 and the lower groove 15 , and are arranged at equal intervals.

[0027] During the sliding process between the rack chuck 4 and the slide rail 8, the balls 6 slide left and right between the corresponding upper groove 14 and ball groove 13, and the lower groove 15 and ball groove 13. The use of balls 6 to slide reduces friction. The balls 6 have point or line contact with the contact surface. Compared to traditional sliding friction (surface contact), the balls 6 convert sliding friction into rolling friction. According to the principles of tribology, the coefficient of rolling friction is much smaller than the coefficient of sliding friction.

[0028] In order to improve the motion accuracy and increase the service life during use

[0029] Under the same pressure conditions, the sliding friction coefficient between metals may be between 0.1-0.5, while the rolling friction coefficient can be reduced to 0.001-0.01.

[0030] Specifically, ball stops 5 are provided at both ends of the rack chuck 4. The position of the ball stops 5 ensures that during rotation, the needle rollers slide only within the two ball grooves 13, limiting the position of the balls 6 and preventing the balls 6 from moving around and affecting the movement of the rack chuck 4 on the slide rail 8. This prevents the balls 6 from falling out of the raceway during rotation or when subjected to large axial forces, ensuring that the balls 6 roll precisely along a predetermined trajectory, thereby enabling precise linear movement of the rack chuck 4. The limiting mechanism allows the balls 6 to rotate within a specific, ideal raceway, avoiding friction between the balls 6 and non-ideal contact surfaces.

[0031] Specifically, the rack chuck 4 has a Z-shaped structure. A Z-shaped rack chuck can contact the clamped object in multiple directions. Compared to a chuck with a simpler structure, its unique shape provides more contact points or areas. For example, when clamping a cylindrical workpiece, different parts of the Z-shaped structure can contact the workpiece from different directions, such as the side and top. This makes the workpiece less likely to rotate or shift within the chuck, thereby improving clamping stability.

[0032] Specifically, the length of the slide rail 8 is twice the length of the rack chuck 4; in the process of clamping the material, the rack chuck 4 can slide horizontally in the slide rail 8 to ensure the sliding stroke of the rack chuck 4 and can clamp the material of the length of the rack chuck 4.

[0033] Specifically, the main body lower end cover 3 is provided with a sliding groove 16 for the rack clamp 4 to slide with; the clamping end of the rack clamp 4 slides horizontally in the sliding groove, and the clamping range and distance of the rack clamp 4 can also be limited.

[0034] Specifically, the motor 11 is provided with a control board 12 electrically connected thereto, through which the motor 11 can be precisely controlled and the switch of the motor 11 can be controlled so as to adjust the torque and speed during the material clamping process, without the need to connect to a host computer, and the operation is simple.

[0035] Specifically, the main housing 1 is provided with a wire crimping cover 10, which can organize and arrange the wires connected to the motor 11, thereby preventing the wires from being randomly placed and causing confusion.

[0036] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of the claims of the present invention.
