Description

Technical Field

[0001] This utility model relates to the field of component clamping technology, and in particular to a fully automatic clamping device for precision components. Background Technology

[0002] In precision manufacturing and electronic processing, the clamping of precision components requires extremely high precision. It is essential not only to ensure clamping stability to prevent component displacement but also to prevent excessive clamping force that could damage the component surface. Existing clamping devices have several limitations: some rely on manual operation, resulting in low efficiency and clamping accuracy significantly affected by human factors; in automated clamping devices, most have fixed structures, making it difficult to flexibly adjust clamping angles and heights, leading to poor adaptability; transmission mechanisms often use single gears or lead screws, which are prone to insufficient clamping synchronization and movement jamming, affecting clamping stability; furthermore, the contact points between clamping components and components lack effective protection, easily causing scratches or indentations on the component surface. In addition, the guide structure design of traditional devices is simple, and long-term use can lead to a decrease in transmission accuracy due to wear, and most devices lack multi-angle rotation capabilities, failing to meet the clamping requirements under complex working conditions. Therefore, there is an urgent need for a precision clamping device that can achieve fully automatic adjustment, stable clamping, strong adaptability, and effective protection of components. Utility Model Content

[0003] To address the problems mentioned above, this utility model adopts the following technical solution:

[0004] An automated precision parts clamping device includes a column, a cylinder vertically mounted on one side of the column, a sliding plate mounted on the output end of the cylinder, a rotary actuator mounted on one side of the sliding plate, a housing connected to one end of the rotary actuator, a pair of first gears rotatably mounted on the inner wall of the housing, the pair of first gears meshing with each other, a sector gear fixedly mounted on one side of the first gears, a T-shaped guide rail mounted on the top inner wall of the housing, a rack slidably connected to the T-shaped guide rail, the rack meshing with the sector gear, a servo motor mounted on one side of the housing, a second gear connected through the housing at the output end of the servo motor, the second gear meshing with the first gear adjacent to it, a T-shaped guide groove mounted on the bottom inner wall of the housing, a first support rod slidably connected within the T-shaped guide groove, a second support rod mounted on one side of the rack, the first support rod and the second support rod jointly connected to a connecting rod, clamping blocks mounted on one side of the connecting rod and the other side of the housing.

[0005] Furthermore, a pair of sliding rod support seats are installed on one side of the column, and a sliding rod is installed between the pair of sliding rod support seats. The sliding rod passes through the sliding plate and is slidably connected to the sliding plate.

[0006] Furthermore, the central angles of the two sector gears are oriented in opposite directions and are symmetrically distributed.

[0007] Furthermore, a through groove is provided on the other side of the box body for sliding of the first support rod and the second support rod.

[0008] Furthermore, the clamping surface of the clamping block is provided with a rubber pad.

[0009] The advantages of this invention are as follows: The device achieves vertical position adjustment through the combination of a column, cylinder, and sliding plate. Combined with a rotary actuator to drive the housing rotation, the clamping angle and height can be flexibly adjusted to meet clamping requirements under different working conditions, improving the adaptability and automation of the device. A pair of meshing first gears, along with the transmission of the sector gear and rack, ensure that the power of the servo motor is stably transmitted to the clamping components, ensuring synchronous clamping actions on both sides. The sector gear design limits the sliding stroke of the rack, preventing over-clamping. Simultaneously, the T-shaped guide rail provides stable guidance for the rack, reducing wobbling during transmission and ensuring clamping accuracy. Rubber pads are placed on the clamping surfaces of the clamping blocks to buffer impact forces during clamping, preventing scratches or damage to the parts' surfaces. This also enhances the friction of the clamping surfaces, improving clamping stability and preventing parts from falling off during handling or processing. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0015] See Figure 1-2 As shown, a fully automatic clamping device for precision parts includes a column 1, a cylinder 2 vertically mounted on one side of the column 1, a sliding plate 3 mounted on the output end of the cylinder 2, a rotary actuator 4 mounted on one side of the sliding plate 3, a housing 5 connected to one end of the rotary actuator 4, a pair of first gears 6 rotatably mounted on the inner wall of the housing 5, the pair of first gears 6 meshing with each other, a sector gear 7 fixedly mounted on one side of the first gears 6, a T-shaped guide rail 8 mounted on the inner top side wall of the housing 5, a rack 9 slidably connected to the T-shaped guide rail 8, and the rack 9 and the sector gear 7... Gear 7 meshes, a servo motor 10 is installed on one side of the housing 5, the output end of the servo motor 10 passes through the housing 5 and is connected to a second gear 11, the second gear 11 meshes with the first gear 6 that is close to it, a T-shaped guide groove 12 is installed on the inner bottom side wall of the housing 5, a first support rod 13 is slidably connected in the T-shaped guide groove 12, a second support rod 14 is installed on one side of the rack 9, the first support rod 13 and the second support rod 14 are connected together to a connecting rod 15, a clamping block 16 is installed on one side of the connecting rod 15 and the other side of the housing 5.

[0016] A pair of slide rod support seats 17 are installed on one side of the column 1, and a slide rod 18 is installed between the pair of slide rod support seats 17. The slide rod 18 passes through the sliding plate 3 and is slidably connected to the sliding plate 3. By setting the slide rod support seats 17 and the slide rod 18 on one side of the column 1, and the slide rod 18 passes through the sliding plate 3 and is slidably connected to it, a stable guide is provided for the vertical movement of the sliding plate 3. This can effectively limit the lateral displacement of the sliding plate 3 during the movement, ensuring that the cylinder 2 drives the sliding plate 3 to drive the housing 5 and the clamping assembly to make precise vertical lifting and lowering movements, avoiding the impact of shaking on the clamping and positioning accuracy, and reducing frictional wear between the sliding plate 3 and the column 1, thus extending the service life of the device.

[0017] The two sector gears 7 are symmetrically distributed with their central angles facing opposite directions. When a pair of first gears 6 rotate synchronously in opposite directions, the symmetrically distributed sector gears 7 can alternately mesh with the rack 9. By changing the direction of the thrust on the tooth surface, the rotational motion of the gears is converted into the linear reciprocating motion of the rack 9. This alternating meshing mechanism avoids excessive slippage of the rack 9 and ensures the continuity of the clamping action. At the same time, the symmetrical structure ensures the balance of the left and right sliding stroke of the rack 9, making the opening and closing distance of the clamping block 16 controllable and adaptable to precision parts of different sizes.

[0018] On the other side of the housing 5, there is a through groove for sliding the first support rod 13 and the second support rod 14, which provides movement space for the first support rod 13 and the second support rod 14.

[0019] The clamping surface of the clamping block 16 is provided with a rubber pad. By utilizing the elastic deformation properties of rubber, the impact force during clamping can be buffered, avoiding scratches, pressure marks and other damage caused by direct contact between the hard clamping block 16 and the surface of precision parts.

[0020] Working principle: Cylinder 2 starts, driving the sliding plate 3 to move vertically along the slide rod 18, adjusting the height of the housing 5 and the clamping block 16; the rotary actuator 4 works, driving the housing 5 to rotate to the required angle, realizing the adjustment of the clamping direction to adapt to different working position requirements. Servo motor 10 starts, and its output drives the second gear 11 to rotate. The second gear 11 meshes with the adjacent first gear 6, transmitting power to the first gear 6, causing it to rotate clockwise. Since the pair of first gears 6 mesh with each other, the clockwise rotating first gear 6 drives the other first gear 6 to rotate synchronously counterclockwise through the meshing of the tooth surfaces. The two first gears 6 respectively drive the coaxially fixed sector gears 7 to rotate synchronously: the clockwise rotating first gear 6 drives the corresponding sector gear 7 to rotate clockwise, and the counterclockwise rotating first gear 6 drives the corresponding sector gear 7 to rotate counterclockwise. Because the two sector gears 7 have opposite central angles and are symmetrically distributed, they form an alternating meshing transmission: when the clockwise rotating sector gear 7 enters the meshing area with the rack 9, it pushes the rack 9 to slide to the right along the T-shaped guide rail 8 through the tooth surface thrust; when the clockwise rotating sector gear 7 rotates out of the meshing area, the counterclockwise rotating sector gear 7 just enters the meshing area, and drives the rack 9 to slide to the left along the T-shaped guide rail 8 through the reverse tooth surface thrust. The reciprocating sliding of the rack 9 is transmitted to the connecting rod 15 through the second support rod 14, while the first support rod 13 slides synchronously along the T-shaped guide groove 12, providing stable support for the connecting rod 15 and ensuring its smooth movement in a straight line. When the rack 9 slides to the left, the connecting rod 15 drives the clamping block 16 on one side to approach the fixed clamping block 16 on the other side of the housing 5, thereby clamping the precision parts. When the rack 9 slides to the right, the connecting rod 15 drives the clamping block 16 on one side to move away from the fixed clamping block 16, thus completing the release action.
