The technical scheme is characterized by comprising a cylinder, wherein a cylinder end plate is arranged at the front end of the cylinder; a fixed block is arranged on the cylinder end plate, and a positioning plate is arranged on the fixed block; the fixed block is also provided with a hinge fixed block, the hinge fixed block is provided with a movable hinge, and one end of the movable hinge, which is far away from the hinge fixed block, is hinged with a pressure arm; the pressing arm is provided with a middle fixed hinge and a positioning pressing block matched with the positioning plate. The utility model discloses simple structure is small and exquisite, and the location that is applicable to little work piece compresses tightly simple to operate moreover.
Description
Technical Field
The utility model relates to a positioning mechanism field, more specifically says that it relates to a little work piece location hold-down mechanism.
Background
When an automatic processing device is designed, an existing small workpiece needs to be positioned and compressed, and is fixed during processing.
However, the existing positioning and pressing mechanism generally adopts at least two cylinders as driving force, and further, the overall size of the mechanism is large. For a workpiece with a small size, a positioning and pressing mechanism with a large size has a problem of position limitation during equipment installation, and the problem needs to be solved urgently.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims to provide a little work piece location hold-down mechanism, it has simple structure smallclothes advantage to be convenient for install.
In order to achieve the above purpose, the utility model provides a following technical scheme:
a small workpiece positioning and pressing mechanism comprises a cylinder, wherein a cylinder end plate is arranged at the front end of the cylinder; a fixed block is arranged on the cylinder end plate, and a positioning plate is arranged on the fixed block;
the fixed block is also provided with a hinge fixed block, the hinge fixed block is provided with a movable hinge, and one end of the movable hinge, which is far away from the hinge fixed block, is hinged with a pressure arm; the pressing arm is provided with a middle fixed hinge and a positioning pressing block matched with the positioning plate.
Furthermore, a positioning pin seat and a positioning groove are respectively arranged on the positioning plate.
To sum up, the utility model discloses following beneficial effect has:
the cylinder is used as a driving force, the positioning plate and the positioning pressing block are close to the workpiece to position and press the workpiece, the stroke is short, and the structure is simple and small, so that the installation is convenient.
Drawings
Fig. 1 is a schematic structural diagram of a small workpiece positioning and pressing mechanism in an embodiment.
In the figure: 1. a cylinder; 11. a cylinder end plate; 12. a fixed block; 2. positioning a plate; 21. positioning a pin boss; 22. positioning a groove; 31. a hinge fixing block; 32. a living hinge; 33. pressing the arm; 34. positioning a pressing block; 4. the middle part is fixed with a hinge.
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):
a small workpiece positioning and pressing mechanism, referring to fig. 1, comprises a cylinder 1, a piston rod of the cylinder 1 is connected with a cylinder end plate 11, and a fixed block 12 is arranged on the cylinder end plate 11; be provided with locating plate 2 on the fixed block 12, locating plate 2 is formed by three extension board connection in this embodiment, wherein is provided with locating pin seat 21 and constant head tank 22 on the locating plate 2 respectively, and locating pin seat 21 and constant head tank 22 are used for fixing a position little work piece.
Referring to fig. 1, a hinge fixing block 31 is further arranged on the fixing block 12, a movable hinge 32 is arranged on the hinge fixing block 31, a pressing arm 33 is hinged to one end, away from the hinge fixing block 31, of the movable hinge 32, and a positioning pressing block 34 matched with the positioning plate 2 is arranged on the pressing arm 33; the pressure arm 33 is further provided with a middle fixed hinge 4, one end of the middle fixed hinge 4 is hinged with the pressure arm 33, and the other end of the middle fixed hinge 4 is fixed.
The working principle is as follows:
the cylinder 1 and the middle fixed hinge 4 are fixed, a small workpiece is placed on the positioning plate 2, the cylinder 1 is started to control the piston rod to extend out, and the positioning plate 2 is close to the positioning pressing block 34, so that the workpiece can be positioned and pressed tightly.
