Abstract
The utility model discloses a positioning device used for manufacturing of the connecting rod cover. The utility model comprises a base, a plurality of No.3 positioning pins for controlling the sliding freedom in thickness direction of workpiece and two rotation freedoms and two No. 2 positioning pins for controlling the sliding freedom in forward and backward movement direction of workpiece and one rotation freedom which are positioned in symmetry of the center of the base. A press plate for fixing the workpiece is correspondingly positioned on one side of the No.3 positioning pin. The center of the base is equipped with a sliding positioning mechanism for controlling the left and right movement freedom of workpiece. The positioning device used for manufacturing of the connecting rod cover has the advantages of the reasonable design, the simple structure, reducing the process accuracy of the manufactured parts and the manufacturing difficulty and promoting the manufacturing efficiency.
Description
Technical field
The utility model relates to a kind of mechanical positioner, particularly relates to a kind of positioner that is used for the processing of connecting rod bowl cover.
Background technology
The non-processing bowl cover of profile is in processing composition surface and drill and ream bolt hole and dowel hole operation, and dowel hole requires very high to the position dimension in semifinishing hole on the composition surface.For satisfying the positioning accuracy of above-mentioned operation, necessary internally hole dimension precision of part last process and endoporus propose high processing request to the positional precision of convex shoulder face, by improving the operation precision of position dimension and aperture size, make the location benchmark of degree of precision for next procedure.The existence of position error has brought certain difficulty for the processing of dowel hole position dimension in the operation.And, in order to control position error, brought certain degree of difficulty also for the location benchmark processing of last process.
The utility model content
The purpose of this utility model is the deficiency that exists at prior art, and a kind of positioner that is used for the processing of connecting rod bowl cover that reduces the operation precision, enhances productivity, reduces production costs is provided.
For achieving the above object, the technical solution adopted in the utility model is: a kind of positioner that is used for the processing of connecting rod bowl cover, comprise base, it is characterized in that: be positioned on the base, with its center is to be symmetrically arranged with a plurality of No. three alignment pins that are used to control thickness of workpiece direction one-movement-freedom-degree and two rotary freedoms and two to be used to control No. two alignment pins that workpiece moves forward and backward the free degree and a rotary freedom, and a side correspondence of described No. three alignment pins is provided with the pressing plate that is used for fixing workpiece; The center that is positioned at base is provided with the slide locating mechanism of the control workpiece move left and right free degree.
The utility model compared with prior art has the following advantages:
(1) the connecting rod bowl cover that uses the utility model positioner to process, after testing, pin-and-hole has controlled to 0.007mm to size 217.5 ± 0.03 errors at part center.
(2) machining accuracy of last process can be reduced to free tolerance, endoporus R161.5 by original half right boring hole site size 212 ± 0.03
0 + 0.03Be reduced to R161.5 ± 0.10.
(3) reduced part to be processed operation difficulty, improved working (machining) efficiency: adopt the utility model positioner, half reboring of workpiece endoporus can use work step of heavy boring cutter to machine, and it is about 50% to shorten process time, has significantly improved working (machining) efficiency.
