Description
Technical Field
The utility model relates to a clamping mechanism field, more specifically says that it relates to an external stay formula clamping mechanism.
Background
In the process of processing, transferring and transporting, the fixing modes adopted for the products generally comprise adsorption, hoisting, clamping and the like.
When an automatic device of the existing product is designed, the existing product is not suitable for conventional adsorption and hoisting modes due to large volume. For the clamping mode, if the mode of inward clamping is adopted, the size of the tool is large, so that an external support type clamping mechanism needs to be designed according to a product, and the size of the tool is reduced.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims to provide an external stay formula clamping mechanism, it has simple structure small and exquisite advantage.
In order to achieve the above purpose, the utility model provides a following technical scheme:
an external-support type clamping mechanism comprises a cylinder fixing plate, wherein a cylinder is arranged at one end of the cylinder fixing plate, and two fixing side plates are symmetrically arranged at the other end of the cylinder fixing plate; the cylinder is provided with a piston rod, the piston rod penetrates through the cylinder fixing plate, and the end part of the piston rod is provided with a connecting shaft positioned between the two fixing side plates; a hinge fixing block is arranged at the end part of the connecting shaft, two movable hinges are symmetrically arranged on the hinge fixing block, a connecting rod is hinged to one end, away from the hinge fixing block, of each movable hinge, and a pin shaft penetrating through the fixed side plate is arranged on each connecting rod; and the two end faces of the connecting rods, which deviate from each other, are respectively provided with a connecting block.
Furthermore, a pressure head is arranged on the end face, far away from the connecting rod, of the connecting block.
Furthermore, an adjusting gasket is arranged between the pressure head and the connecting block.
Furthermore, a limiting plate is arranged between the two fixed side plates, and a guide post penetrating through the limiting plate is arranged on the end face, far away from the connecting shaft, of the hinge fixing block.
To sum up, the utility model discloses following beneficial effect has:
the cylinder is adopted to control the two connecting blocks to realize the outward-supporting clamping of the product, the tool volume can be reduced, and the structure is simple and the stability is good.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
Example (b):
an external-support type clamping mechanism, referring to fig. 1 and 2, comprises a cylinder fixing plate 11, wherein a cylinder 2 is arranged at one end of the cylinder fixing plate 11, and two fixing side plates 12 are symmetrically arranged at the other end of the cylinder fixing plate 11; the cylinder 2 is provided with a piston rod 21, the piston rod 21 passes through the cylinder fixing plate 11, and the end part of the piston rod is provided with a connecting shaft 31 positioned between the two fixing side plates 12; a hinge fixing block 32 is arranged at the end part of the connecting shaft 31, two movable hinges 4 are symmetrically arranged on the hinge fixing block 32, a connecting rod 5 is hinged to one end, far away from the hinge fixing block 32, of each movable hinge 4, and a pin shaft 51 penetrating through the fixed side plate 12 is arranged on each connecting rod 5; the end faces of the two connecting rods 5 which deviate from each other are respectively provided with a connecting block 6.
Referring to fig. 2, a limiting plate 13 is arranged between the two fixed side plates 12, a guide post 33 penetrating through the limiting plate 13 is arranged on the end surface of the hinge fixing block 32 away from the connecting shaft 31, and the guide post 33 and the limiting plate 13 are matched to play a role in guiding and limiting.
Referring to fig. 1 and 2, the end face of the connecting block 6, which is far away from the connecting rod 5, is symmetrically provided with a pressure head 61, and an adjusting gasket 62 is arranged between the pressure head 61 and the connecting block 6.
The working principle is as follows:
under normal conditions, two connecting blocks 6 are close to the shrink each other, and the during operation starts 2 control piston rods 21 of cylinder and removes, drives two connecting rods 5 and is close to each other near the tip of hinge fixed block 32, and then connecting rod 5 rotates around round pin axle 51, makes two connecting blocks 6 keep away from each other and opens, and two connecting blocks 6 after the external stay can the stable clamp product.
