Description
Technical field
The utility model relates to be machined and technical field of mold, specially accurate resetting structure.
Background technique
Machining refers to the process of to be changed by outer dimension or performance of a kind of mechanical equipment to workpiece, is pressed and is added
Difference in work mode can be divided into machining and pressure processing, and the production process of machine, which refers to from raw material, is made the complete of product
Portion's process, including the transport and preservation of raw material, the preparation of production, the manufacture of blank, the processing of part for production of machinery
And heat treatment, the assembly and debugging of product, the contents such as paint and packaging, the content of production process is very extensive, and modern enterprise is used
The principle and method tissue of system analysis engineering produce and Instructing manufacture, and machine components are by several surface compositions, research zero
The relativeness on part surface, it must be determined that a benchmark, benchmark be on part be used to determine other point, line, surface position institute according to
According to point, line, surface, according to the different function of benchmark, benchmark can be divided into two class of design basis and technological datum, utilize machining
It processes fixed pin holes directly in template or mechanical structured member to be located by connecting with fixed pin again, existing location structure is fixed
Position precision is not high enough, and repeatable accuracy is low, reduces working efficiency, and the quality of production is low, increases the working strength of worker, is unfavorable for
The use of people.
Utility model content
The purpose of this utility model is to provide accurate resetting structures, have the advantages of accurate resetting, solve
Existing location structure repetitive positioning accuracy low problem.
To achieve the above object, the utility model provides the following technical solutions: accurate resetting structure, including the first machine
The inner cavity of tool part or template and the second machine components or template, first machine components or template is provided with fixed pin, institute
The inner cavity for stating the second machine components or template is provided with bushing, and the surface that the fixed pin is located at bushing inner cavity one end is arranged with rolling
Pearl bushing, and the inner wall interference fit of ball bushing, fixed pin and bushing, the plate that bushing is installed are not limited, be can be
First machine components or template are also possible to the second machine components or template.
Compared with prior art, the beneficial effects of the utility model are as follows:
1, the utility model passes through the first machine components of setting or template, the second machine components or template, fixed pin, bushing
With being used cooperatively for ball bushing, solve the problems, such as that existing location structure repetitive positioning accuracy is low, the precision resetting
Structure has the advantages of accurate resetting, improves work efficiency, and improves the quality of production, is hardly damaged, registration, energy
It is enough enterprise's save the cost, can reuses, cumulative errors can be eliminated, reduce the working strength of worker, be conducive to
The use of people, is worthy to be popularized.
2, for the utility model by cooperating conventional locating pins structure to be used together, i.e. realization high shear strength is able to achieve essence again
Close resetting.Suitable for high-accuracy location structure, is conducive to the use of people, is worthy to be popularized.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the connection schematic diagram of the utility model ball bushing and bushing.
In figure: 1 first machine components or template, 2 second machine components or template, 3 fixed pins, 4 bushings, 5 ball bushings.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Accurate resetting structure referring to FIG. 1-2, including the first machine components 1 or template 1 and the second machine components 2
Or template 2, the inner cavity of the first machine components 1 or template 1 are provided with fixed pin 3, the inner cavity of the second machine components 2 or template 2 is set
It is equipped with bushing 4, one end that fixed pin 3 is located at 4 inner cavity of bushing is equipped with ball bushing 5, and ball bushing 5, fixed pin 3 and bushing
4 inner wall interference fit passes through the first machine components 1 of setting or template 1, the second machine components 2 or template 2, fixed pin 3, lining
Set 4 and ball (needle) bushing 5 are used cooperatively, and solve the problems, such as that existing location structure repetitive positioning accuracy is low, the precision
Resetting structure, has the advantages of accurate resetting, improves work efficiency, and improves the quality of production, is hardly damaged, and positions
It accurately, can be enterprise's save the cost, shearing strength is high, can reuse, can eliminate cumulative errors, reduce worker
Working strength, be conducive to the use of people, be worthy to be popularized.
In use, between fixed pin 3, bushing 4, ball bushing 5 can be achieved interference fit while template or structural member not
It can lead to the characteristic of deformation because of interference,.
In summary: the precision resetting structure passes through the first machine components 1 of setting or template 1, the second machine components
2 or template 2, fixed pin 3, bushing 4 and ball bushing 5 be used cooperatively, solve existing location structure repetitive positioning accuracy
The problem of low and machine components or template deformation.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
