Description

A Reconfigurable Fixture System

technical field

The invention relates to the field of clamps, in particular to a reconfigurable clamp system.

Background technique

In the field of manufacturing, the processing of composite material components and sheet metal parts is very routine and basic. In industrial production, these components are rarely formed at one time, and generally require secondary processing, such as cutting, drilling, and surface cutting. During secondary machining, the workpiece requires continuous support to avoid excessive deformation, shifting and vibration. Otherwise, the workpiece may not meet the dimensional accuracy requirements, resulting in rework or scrap. However, most continuously supported fixtures, that is, special fixtures, are only dedicated to the processing and assembly of a certain type of specific parts, which greatly limits the flexibility of production and processing. As more and more companies pursue efficient and fast manufacturing goals, fixture systems that can provide higher manufacturing flexibility in the machinery and aerospace manufacturing industries have emerged. Two flexible fixture systems mainly used in industrial production include combined fixtures systems and reconfigurable support systems. The combined fixture system designs and assembles a series of modular units according to the shape and processing requirements of the workpiece, so as to meet the needs of positioning and clamping. But this device needs quite a long time to assemble and adjust workpieces of different shapes, and the mass of the combined fixture module itself is large, and it is very inconvenient to assemble, disassemble and move.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention, should understand that following specific embodiment is only for illustrating the present invention and is not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand the present invention Modifications in various equivalent forms fall within the scope defined by the appended claims of the present application.

Please refer to Fig. 1 and Fig. 2, the present invention discloses a reconfigurable clamp system 100, including a frame 10, a moving plate 1, a moving column 2, a vertical positioning assembly of the moving column and an integral plate clamping structure, Wherein there are a plurality of moving columns 2, and the distribution mode arranged in a square array, the moving column 2 and the moving plate 1 can move up and down in the vertical direction, and the vertical positioning system of the moving column includes a position sensor input terminal 6, Control system 7, DC power supply 8, spring type electromagnet 3, ejector rod 4 and the support plate 5 that is installed on the inner top of frame, described position sensor input end 6 and spring type electromagnet 3 are connected with the input of described control system 7 respectively terminal is connected to the output end, the ejector rod 4 is connected to the spring electromagnet 3, the spring electromagnet 3 is a small DC spring electromagnet, and the integral plate clamping structure includes a clamping plate 11, a locking handle 9 and a draw bar 12, the clamping plate 11 is placed on the upper surface of the frame 10, but there is no connection with the frame 10, and the frame 10 and the clamping plate 11 are provided with a plurality of The moving column 2 corresponds to and cooperates with the small hole 13 , and the moving column 2 naturally falls on the moving plate 1 through the small hole 13 . The locking handle 9 is fixed on the edge of the frame 10, the drawbar 12 is fixed on the clamping plate 11 by small screws, and the rotating shaft of the locking handle is provided with gears, and the clamping plate is provided with The gear rack matched with it constitutes a gear/rack pair, which converts the rotation of the locking handle into the translation of the clamping plate, thereby clamping the moving column; in addition, the conversion between rotation and linear movement can also be used in the following ways: The locking handle is provided with a waist hole or an oval hole, wherein the traction rod passes through the above waist hole or oval hole, and when the locking handle is rotated, the traction rod can be driven to move left and right so that the clamping plate moves horizontally.

Working principle: the vertical positioning assembly of the moving column is used to control the stop and movement time of the single moving column 2 in the vertical direction, and the input terminal 6 of the position sensor sends the acquired information of the height of the single moving column 2 into the control system 7 , when consistent with the set height, the control system 7 drives the spring electromagnet 3 to quickly drive the ejector rod 4 through the electromagnetic induction phenomenon in the energized state, and combines the action of the support plate 5 on the moving The column 2 is clamped and positioned, and automatically returns under the action of the spring force when the power is off. The integral plate clamping structure is used for overall positioning and clamping of all moving columns 2. When each moving column 2 reaches the required position and is clamped and positioned by the ejector rod 4, the locking handle 9 is rotated so that The traction rod 12 moves to the right end, which also drives the clamping plate 11 to move to the right together, so that the moving column 2 in the small hole 13 can be clamped, so that the clamping and positioning of all the moving columns 2 is realized. The clamping method is more reliable, which ensures that the workpiece can withstand large external forces during processing.

In this embodiment, the controlled mobile plate 1 moves up and down on the vertical sliding track. When moving the plate 1 at a constant speed in the vertical direction, the moving column 2 is still relative to the mobile plate 1, and also moves vertically at the same speed. direction to move. Once the stop signal is received, the vertical positioning component of the moving column will position the moving column 2 , while the moving flat plate 1 continues to move downwards, thereby realizing the separation of the moving column 2 and the moving flat plate 1 . The difference in stopping heights of different moving columns 2 due to different stopping times forms a spatial curved surface to meet the positioning of workpieces with different surface shapes.
