Description

High-precision clamping mechanism

Technical Field

The utility model relates to an automated production field specifically is a high accuracy fixture.

Background

When bottled containers with arc outer walls, such as round containers and oval containers, are automatically cleaned and filled, the outer walls of the containers need to be clamped by a clamping mechanism, and then the bottled containers are rotated, lifted and the like with the assistance of a driving mechanism; however, for example, because the ampoule bottle has a small capacity, especially the diameter of the bottle opening is smaller than the bottle body, the requirement for precision is very high when the ampoule bottle is automatically produced, and when cleaning, the bottle opening needs to be ensured to be aligned with the nozzle.

As shown in figure 1, in order to ensure that ampoule bottles and the like cannot move after being clamped, opposite cushion blocks are arranged on clamping plates arranged on the left side and the right side of the clamping device at intervals, clamping grooves are formed in the cushion blocks, and when the clamping device works, the clamping plates arranged on the two sides of a container move towards the container to enclose the container in the clamping grooves, so that clamping is completed. In order to adapt to containers with different shapes and errors of the outer diameters of the matched containers, the clamping grooves are usually triangular, so that the requirement on the machining accuracy of the clamping grooves in the cushion blocks on two sides is high, if the clamping grooves on the two sides are inconsistent as shown in the figure 1 or the angles of the side edges of the clamping grooves are different, the phenomenon that a bottle body transversely moves and the like possibly occurs when the containers are clamped, and the positions of guide pillar bottle openings and the spray heads are staggered.

SUMMERY OF THE UTILITY MODEL

The utility model aims at above problem, provide a high accuracy fixture, can improve the centre gripping precision.

In order to realize the above purpose, the utility model adopts the technical scheme that: the utility model provides a high accuracy fixture, it includes the grip block that sets up relatively, and the distance between the grip block of both sides can shorten or increase, is provided with the cushion on the grip block, is provided with the triangle-shaped draw-in groove relative with the opposite side grip block on only the cushion of one side.

Further, for production safety, the clamping plate further comprises a limiting mechanism for limiting the moving range of the clamping plate.

Furthermore, stop gear is including setting up in the vertical spacing portion in the grip block outside and setting up in the horizontal spacing portion between two grip blocks, and vertical spacing portion is used for controlling the open maximum angle of grip block, and horizontal spacing portion is used for controlling the minimum distance between two grip blocks.

Furthermore, for convenient replacement, the transverse limiting part is a limiting bolt, the limiting bolt is in threaded connection with the clamping plate on one side, and the length of the limiting bolt extending out of the clamping plate can be quickly adjusted by rotating the limiting bolt, so that the purpose of adapting to containers with different outer diameters is achieved.

Furthermore, in order to control the opening and closing of the clamping plates on the two sides, gears which are meshed with each other are arranged on the clamping plates on the two sides, and gear ends of the clamping plates are connected with the pin shafts.

The utility model has the advantages that: the triangular clamping grooves are formed in the clamping plate on only one side, when the clamping plate clamps the container, the container is in contact with the two side edges of the triangular clamping grooves and the clamping plate, the container is firmly clamped in a three-point circle mode, and compared with a four-point circle fixing mode in which the triangular grooves are formed in the two sides, the phenomenon that the container moves and the like in the clamping process can be guaranteed due to the fact that the adaptive degree of the triangular clamping grooves on the two sides does not need to be considered; meanwhile, the cushion block is arranged on the clamping plate on only one side, so that when a plurality of clamping mechanisms are assembled together, the gap between every two adjacent clamping mechanisms can be reduced, the number of the clamping mechanisms is increased in a limited space, and the working efficiency is improved.
