Description

Double-point linkage clamping device
Technical Field
The utility model relates to a two point linkage clamping device belongs to machining technical field.
Background
In the machining technology, the clamping requirement on a workpiece is very high, in the clamping of a bench worker, the flat tongs which are usually used are used for clamping, when planes or key grooves are milled on some small parts, the milling force is small and stable, the flat tongs are used for clamping complex or irregular parts, the clamping is time-consuming and is not firm, if the part is clamped insecure, the phenomenon that the parts fall off easily occurs in the machining process, if the parts fall off, the safety of machining equipment can be greatly threatened, and even, the injury can be caused to an operator. If the productivity is low for the long and large-scale production of the parts, the design of the double-point linkage clamping device is necessary for saving the production cost and improving the production efficiency.
SUMMERY OF THE UTILITY MODEL
In order to solve the above problems, the objective of the present invention is to solve the deficiencies of the prior art, and an object of the present invention is to provide a double-point linkage clamping device.
In order to solve the above problems, the utility model discloses a realize through following technical scheme: a double-point linkage clamping device comprises a clamp body, a supporting pin, an inner screw, a supporting plate, a screw rod, a nut, a horizontal overturning pressing plate, a workpiece and a positioning pin; the method is characterized in that: the clamp body is L-shaped; the two support pins are arranged on the upper plane of the fixture body and are in interference fit; the inner screw is used for installing the supporting plate seat on the fixture body; the bearing plate is arranged on the bearing plate seat through a pin, and the bearing plate can rotate on the pin; the screw rod is connected to the right side of the support plate through a pin; the left side of the horizontal overturning pressing plate is arranged on a pin shaft on the upper left side of the fixture body, the middle part of the horizontal overturning pressing plate is contacted with a workpiece, and the right side of the horizontal overturning pressing plate is connected with a screw rod and a nut; the positioning pin is arranged in the mounting hole on the left side of the fixture body and is in interference fit with the mounting hole; the workpiece is arranged on the supporting pin and on the right side of the positioning pin, and the right side of the workpiece just contacts the supporting plate.
The utility model has the advantages that: the clamping device has the advantages of fast, accurate and firm workpiece clamping, simple structure, safety, reliability, easy operation and the like.
Drawings
Fig. 1 is a schematic structural diagram of a double-point linkage clamping device.
Detailed Description
As shown in fig. 1, a double-point linkage clamping device is composed of a clamp body 1, a supporting pin 2, an inner screw 3, a supporting plate 4, a screw rod 5, a nut 6, a horizontal turning pressing plate 7, a workpiece 8 and a positioning pin 9; the method is characterized in that: the clamp body 1 is L-shaped; the two support pins 2 are arranged on the upper plane of the clamp body 1 and are in interference fit; the inner screw 3 is used for installing the supporting plate seat on the fixture body; the bearing plate 4 is arranged on the bearing plate seat through a pin, and the bearing plate can rotate on the pin; the screw rod 5 is connected to the right side of the support plate through a pin; the left side of the horizontal overturning pressing plate 7 is arranged on a pin shaft on the upper left side of the fixture body, the middle part of the horizontal overturning pressing plate is contacted with a workpiece, and the right side of the horizontal overturning pressing plate is connected with a screw rod and a nut; the positioning pin 9 is arranged in the mounting hole on the left side of the fixture body and is in interference fit with the mounting hole; the workpiece 8 is arranged on the supporting pin 2 and on the right side of the positioning pin 9, and the right side of the workpiece just contacts the supporting plate 4. When the device works, a workpiece is firstly placed between the supporting pin and the positioning pin, the right side of the device is contacted with the supporting plate, the lower horizontal overturning pressing plate is placed, the middle part of the device is contacted with the workpiece, the screw rod is pulled up, the nut is screwed down, the horizontal overturning pressing plate is downward, the screw rod upwards drives the supporting plate to rotate around the pin shaft, and therefore the left convex claw of the supporting plate and the middle convex claw of the horizontal overturning pressing plate simultaneously press the workpiece; when the nut is loosened, the screw rod is put down, and the workpiece can be taken down after the horizontal overturning pressing plate is lifted.
The above has been disclosed with a preferred embodiment, but it is not intended to limit the present invention, and all technical solutions obtained by equivalent replacement or equivalent transformation are all within the scope of the present invention.
