Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a clamp used for automatic assembly of tiny parts. Background Art

[0002] With the continuous development of MEMS and technology, MEMS products are constantly developing towards miniaturization and diversification. As an extremely important part of MEMS product manufacturing, the precision assembly technology of tiny devices faces increasing challenges. In MEMS products, tiny parts usually have complex structures, different shapes, are difficult to clamp, and are easily disturbed by micro-scale effects and adsorption forces such as electrostatic force and magnetic force, so it is difficult to ensure assembly efficiency and assembly accuracy. During and after the assembly of tiny parts, specific fixtures are required to position and clamp them, especially after alignment and installation, the aligned and assembled components need to be fixed and locked to facilitate subsequent other processes such as part gluing or welding.

[0003] For example, the Chinese utility model patent with the authorization announcement date of 2015-4-17 and the authorization announcement number of CN204621638U discloses a multi-station lathe fixture, which is composed of a base, a limit bolt, a locking bolt, a sliding clamp seat, a clamp block, a clamp block bolt and a workpiece mounting groove. The base is connected to the lathe spindle, and the base is connected to the dovetail groove of the sliding clamp seat. The sliding clamp seat is fixed to the base by the locking bolt, and the moving position of the sliding clamp seat is adjusted by the limit bolt. The dovetail groove of the clamp block is connected to the sliding clamp seat, and the clamp block clamps the part in the workpiece mounting groove and is locked by the clamp block bolt. The fixture has a simple structure, a reasonable design, and is easy to operate. By clamping the parts at one time, the shapes of parts in multiple positions can be processed, thereby improving the part processing accuracy and production efficiency.

[0004] However, when the multi-station lathe fixture is used, when clamping the parts, it is necessary to manually tighten the bolts and clamp the parts with the clamping blocks, which is inefficient. When the parts are clamped and positioned, the parts cannot be quickly limited and fixed. Utility Model Content

[0005] Aiming at the technical problem that the traditional clamping of tiny parts adopts manual assembly positioning and locking, and the parts cannot be quickly limited and fixed, the utility model provides a clamp for automatic assembly of tiny parts.

[0006] In order to achieve the above object, the technical solution of the present invention is achieved as follows:

[0007] A fixture for automatic assembly of tiny parts, comprising a base, a connection plate arranged on the base, a bracket installed on the upper side of the connection plate, a ring sleeve arranged on the bracket, a positioning hole arranged on the ring sleeve, the upper part of the tiny part is plugged into the positioning hole, and the lower part passes through the positioning hole, the ring sleeve is installed with a limit table for axially stopping the tiny part, at least two clamping plates are arranged on the connection plate, the clamping plates are distributed around the axis of the ring sleeve, and each clamping plate is connected to a clamping drive device. The fixture realizes automatic clamping and positioning of tiny parts through the combination of the clamping plates and the clamping drive device, has a good fixing effect, and is fixed through the axial stop limit table, ensuring the stability and accuracy of assembly.

[0008] Furthermore, the connection plate is provided with a vertical plate, and the vertical plates are provided in four groups of two, and the two vertical plates in each group are rotatably connected with a clamping plate. The clamping plate can be flexibly rotated to adapt to tiny parts of different shapes and sizes. The rotation connection between each group of vertical plates can provide better clamping force and stability, ensuring the accurate positioning and fixation of tiny parts during the assembly process. In addition, the connection between the clamping plate and the clamping drive device allows the clamping force to be controlled by the drive device to achieve an automated clamping operation.

[0009] Furthermore, connecting columns are provided on both sides of the clamping plate, and the two vertical plates are provided with holes opposite to each other, and the connecting columns are plugged into the holes. By plugging the connecting columns into the holes of the vertical plates, the clamping plate and the vertical plates can be detachably connected. This design can easily replace the clamping plate to adapt to different sizes and shapes of tiny parts.

[0010] Furthermore, the clamping plate is a horizontally placed U-shaped plate, and the openings of each U-shaped plate face each other. This design enables the clamping plate to better clamp and fix tiny parts, providing a more stable clamping effect.

[0011] Furthermore, the connection disk is coaxially arranged with the ring sleeve, which means that the central axes of the connection disk, the ring sleeve and the tiny parts are coincident, and the coaxial arrangement can ensure that the force transmission between the connection disk and the ring sleeve is more uniform and effective, reducing the force dispersion or failure caused by eccentricity or misalignment.

[0012] Furthermore, the clamping drive device includes a cylinder, which is arranged at the center of the connecting disk, and a pressure plate is provided at the output end of the cylinder, and the pressure plate is pressed against the lower end of the clamping plate, and the lower ends of the clamping plates are connected by springs. Through the combination of the cylinder and the pressure plate, a stable and controllable clamping force can be provided. The output capacity of the cylinder can be adjusted as needed to ensure that the clamping plate can firmly clamp the workpiece to prevent it from sliding or falling off. The spring connected to the lower end of the clamping plate can provide a certain flexibility and adaptability. When clamping workpieces of different sizes or shapes, the spring can automatically adjust and provide appropriate pressure to ensure that the clamping effect is more stable and reliable. As a driving device, the cylinder has a fast response and efficient clamping speed. It can achieve the clamping and release of the clamping plate in a short time, thereby improving production efficiency.

[0013] Furthermore, the pressing plate is located at the symmetric center of the two clamping plates, and the diameter of the pressing plate is greater than the distance between the two opposite clamping plates. Since the pressing plate is located at the symmetric center of the opposite clamping plates, when the clamping plates clamp the workpiece, the force of the pressing plate will be evenly distributed on both sides of the clamping plates. This ensures that the tiny parts are clamped evenly, avoiding deformation or damage of the tiny parts due to uneven clamping force.

[0014] Furthermore, an anti-slip block is provided at one end of the clamping plate for clamping tiny parts, and the anti-slip block is a semi-cylindrical silicone anti-slip block. The silicone anti-slip block has good friction characteristics and can increase the friction between the clamping plate and the workpiece. This can ensure that the workpiece will not slide or shift during the clamping process, and improve the stability and reliability of the clamping. The silicone anti-slip block has a soft characteristic and can buffer and protect the surface of the workpiece. It can reduce the friction and scratches on the surface of the workpiece during the clamping process, and avoid damage or marks on the workpiece. The semi-cylindrical silicone anti-slip block can better adapt to the surfaces of workpieces of different shapes. It can provide a wider contact area, ensure that the clamping force is evenly distributed, and is suitable for clamping workpieces of various shapes.

[0015] Furthermore, the ring sleeve is fixedly connected to the upper end of the bracket through its outer circumferential surface, and the bracket includes a plurality of circumferentially distributed L-shaped bent rods. The fixed connection between the ring sleeve and the upper end of the bracket can ensure a firm connection between the ring sleeve and the bracket. This can prevent the ring sleeve from loosening or falling off during use, thereby ensuring the stability and reliability of the equipment. The circumferential distribution of the L-shaped bent rods can provide uniform support force and enhance the structural strength of the bracket. This can effectively withstand the effects of external forces, reduce the risk of deformation and damage, and extend the service life of the equipment.

[0016] Furthermore, the clamping plate is an inclined L-shaped plate, and the openings of each L-shaped plate are facing oppositely. The clamping drive device includes a cylinder, and the cylinder is arranged at the center of the connecting plate. The output end of the cylinder is provided with a pressure plate, and the pressure plate is crimped to the lower end of the L-shaped plate. The lower ends of each L-shaped plate are connected by a spring, and the other end of the L-shaped plate is used to clamp tiny parts. By adjusting the angle and position of the clamping plate, a variety of clamping methods can be achieved, and the applicability and flexibility of the equipment can be improved. In this way, automated control can be achieved, and work efficiency and accuracy can be improved. The clamping plate can be quickly fixed and locked to solve the problem that traditional manual positioning is time-consuming and not precise enough.

[0017] Beneficial effects of the present invention:

[0018] Tiny parts can be quickly positioned using the limit table and quickly fixed and locked using the clamp, solving the problem of traditional manual positioning being time-consuming and imprecise. BRIEF DESCRIPTION OF THE DRAWINGS

Since the pressing plate 10 is located at the symmetric center of the clamping plates 7, when the clamping plates 7 clamp the workpiece, the force of the pressing plate 10 will be evenly distributed on both sides of the clamping plates 7. In this way, the tiny parts 5 can be evenly clamped, avoiding deformation or damage of the tiny parts 5 due to uneven clamping force.

[0033] Example 8, as a preferred embodiment of a fixture for automatic assembly of small parts, Figure 3As shown, the difference from Example 7 is that an anti-sliding block 13 is provided at one end of the clamping plate 7 for clamping tiny parts, and the anti-sliding block 13 is a semi-cylindrical silicone anti-sliding block 13.
