Abstract
The utility model discloses a kind of 3 synchronous self-centering structures for fixture, belong to centering apparatus technical field.The self contering structure includes three pieces of connecting plates positioned at piston rod part, and the piston rod is rotated with connecting plate and is connected, and the other end of connecting plate rotates connection connecting rod, and the bottom of connecting rod, which is rotated, is provided with pressure head at the top of the riser that is connected, connecting rod.The beneficial effects of the utility model are：Drive connecting plate is moved up and down using the piston rod of oil cylinder, makes three strong points connected with connecting plate, while expanding outwardly and to contract, adjective-centre structure is simple, and centering is accurate, efficiency high of feeling relieved, and manufacturing cost and maintenance cost are low.
Description
Technical field
The utility model is related to a kind of Self-centering device of fixture, belongs to centering apparatus technical field.
Background technology
Workpiece blank needs first to position the location of workpiece before being fixedly clamped on fixture, and traditional positioning is using artificial side
Formula, location efficiency is low and positioning has error；To improve operating efficiency, self-centering apparatus arises at the historic moment, of the prior art
Self-centering apparatus, complicated, maintenance cost is high.
Utility model content
To solve the defect that prior art is present, the purpose of this utility model is to provide a kind of simple in construction, centering efficiency
High 3 synchronous self-centering structures for fixture.
The technical solution of the utility model is：A kind of 3 synchronous self-centering structures for fixture, including positioned at piston
Three pieces of connecting plates at the top of bar, the piston rod is rotated with connecting plate and is connected, and the other end of connecting plate rotates connection connecting rod, connecting rod
Bottom, which is rotated, is provided with pressure head at the top of the riser that is connected, connecting rod.
The pressure head surface is sphere.
The adjusting pad for being used for adjusting ram position is provided with the top of the connecting rod.
The piston rod is rotated by bearing pin a with connecting plate and is connected.
The connecting plate is rotated with connecting rod by bearing pin b and is connected.
The piston rod is hydraulic drive piston bar.
The connecting rod is rotated by bearing pin c with fixed board and is connected.
The beneficial effects of the utility model are：Drive connecting plate is moved up and down using the piston rod of oil cylinder, makes to connect with connecting plate
Three strong points, while expanding outwardly and to contract.When workpiece is loaded on fixture, self contering structure, which is in, to be shunk
State, the workpiece being so positioned can be enclosed on Self-centering device, and then Self-centering device is slowly expanded, and all connect until 3 points
When contacting the positioning hole inwall of workpiece, i.e., the location of workpiece is locked.Adjective-centre structure is simple, and centering is accurate, efficiency high of feeling relieved, manufacture
Cost and maintenance cost are low.

Embodiment
1-3 is described further to the utility model below in conjunction with the accompanying drawings：
A kind of 3 synchronous self-centering structures for fixture, including three pieces of connecting plates 2 positioned at the top of piston rod 1, it is described
Piston rod 1 is rotated with connecting plate 2 and is connected, and the other end of connecting plate 2 rotates connection connecting rod 3, and the bottom of connecting rod 3, which is rotated, to be connected
Riser 4, the top of connecting rod 3 is provided with pressure head 5.
The surface of pressure head 5 is sphere.
The top of connecting rod 3 is provided with the adjusting pad 6 for being used for adjusting the position of pressure head 5.By adjusting adjusting pad 6, to pressure head 5
Position carry out pre-adjustment, make three pressure heads 5 after opening, workpiece be locked position be predeterminated position.
The piston rod 1 is rotated by bearing pin a7 with connecting plate 2 and is connected.
The connecting plate 2 is rotated with connecting rod 3 by bearing pin b8 and is connected.
The piston rod 1 is hydraulic drive piston bar.
The connecting rod 3 is rotated by bearing pin c9 with fixed board 4 and is connected.
Drive connecting plate 2 is moved up and down using the piston rod 1 of oil cylinder, makes three strong points connected with connecting plate 2, while outwards
Expansion and to contract.When workpiece is loaded on fixture, three pressure heads 5 of self contering structure are in contraction state, so
The workpiece being positioned can be enclosed on Self-centering device, and then Self-centering device is slowly expanded, until the pressure head 5 of three points all connects
When contacting the positioning hole inwall of workpiece, i.e., the location of workpiece is locked.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model technical principle is not departed from, some improvement and modification can also be made, these change
Enter and protection domain of the present utility model is also should be regarded as with modification.
