Description
Technical Field
The utility model relates to an anchor clamps technical field especially relates to an automatic positioning fixture in branch.
Background
In machining, some workpieces need to be positioned in different centers so as to be symmetrically machined, a common method is to perform multilayer positioning on a clamp, such as a positioning pin, an ejector rod, a positioning block and the like, the operation is troublesome, the efficiency is low, the precision of the clamp is reduced after the clamp is used for a long time, the accurate positioning can be realized through the method, and at the moment, the clamp needs to be adjusted and repaired, which is time-consuming and labor-consuming.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to prior art not enough, and provide an automatic positioning fixture in branch, it makes the work piece automatic with the center centering of jack catch through opening the jack catch that closes to centre or both sides simultaneously.
The utility model provides a technical scheme that its technical problem adopted is: the automatic centering positioning fixture comprises a base, wherein a hydraulic oil cylinder is arranged at the bottom of the base, a centering seat is fixedly connected to the end part of a piston rod of the hydraulic oil cylinder, a shifting lever is arranged on each of the left side and the right side of the base and is in an L shape, the shifting lever is rotatably connected with the base at an L-shaped inflection point through a pin shaft, a connecting rod which is respectively hinged with the shifting lever and the centering seat is arranged between the shifting lever and the centering seat, and a clamping jaw is fixed to the other end of the shifting lever.
Further, the clamping jaw is perpendicular to the moving plane of the shifting rod.
Furthermore, the base comprises a bottom plate and a rectangular frame which is communicated up and down, the hydraulic oil cylinder is fixed on the bottom plate, and the shifting lever is arranged inside the rectangular frame.
The utility model has the advantages that: the automatic centering positioning fixture comprises a base, wherein a hydraulic oil cylinder is arranged at the bottom of the base, a centering seat is fixedly connected to the end part of a piston rod of the hydraulic oil cylinder, a shift lever is arranged on each of the left side and the right side of the base and is in an L shape, the shift lever is rotatably connected with the base at an L-shaped inflection point through a pin shaft, a connecting rod which is respectively hinged with the shift lever and the centering seat is arranged between the shift lever and the centering seat, and a clamping jaw is fixed to the other end of the shift lever.

Detailed Description
The following detailed description of the present invention is provided in connection with the accompanying drawings and the embodiments, and is not intended to limit the scope of the invention.
As shown in fig. 1 and 2, the automatic centering positioning fixture of the embodiment includes a base 1, a hydraulic cylinder 2 is disposed at the bottom of the base 1, a centering seat 3 is fixedly connected to an end of a piston rod of the hydraulic cylinder 2, a shift lever 4 is disposed on each of left and right sides of the base 1, the shift lever 4 is L-shaped, the shift lever 4 is rotatably connected to the base 1 at an L-shaped inflection point through a pin shaft, a connecting rod 5 is disposed between the shift lever 4 and the centering seat 3 and is respectively hinged to the shift lever 4 and the centering seat 3, and a claw 6 is fixed to the other end of the shift lever 4.
The utility model relates to a mechanical fixture's supplementary anchor clamps can divide the centre location to gliding work piece on mechanical fixture, pass the work piece to the center from both sides promptly, make the work piece automatic to the center location in passing. When the clamping device is used, the hydraulic oil cylinder 2 needs to be extended out, the driving lever 4 is driven to be opened towards two sides through the connecting rod 5, and then the clamping jaw 6 is used for clamping the outer side of a workpiece to be pushed inwards.
The clamping jaw 6 is in a flat plate shape and is connected with the shifting rod 4 through a bolt, and in order to prevent the clamping jaw 6 and the shifting rod 4 from warping due to unevenness of contact surfaces, a clearance gap is formed between the contact surfaces of the clamping jaw 6 and the shifting rod 4. The jaws 6 can also adopt other configurations in order to centre different workpieces.
The base 1 is provided with at the work piece side and keeps away a position arc breach, base 1 passes through bottom plate 11 is fixed in the workstation, thereby can the adjustment position to the well fixed position of work piece.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
