Description
Technical field
The utility model relates to measurement mechanism.
Background technology
In industry component three-D measuring machine on measurement and positioning be all manual measurement substantially or set up the automatic single-piece of workpiece coordinate and measure.The shortcoming of prior art: one is because adopt hand dipping, manually get some during measurement, impact by personnel is measured the position of getting a little at every turn and is not the same, therefore (estimator uses a surveying instrument to the repeatability measured, variation to a certain characteristic of Same Part takes multiple measurements) poor, the repeatability (different estimators uses identical measurer, and the measurement mean value measuring a characteristic of a part is deteriorated) measured in addition is also very poor; Two is set up the automatic single-piece of workpiece coordinate to measure, a part can only be measured at every turn, if measured in enormous quantities (as CPK investigation), measure efficiency lower, the process that simultaneously measures often more replaces a part and all again manual measuring basis face and reference axis must also affect measurement efficiency.
Utility model content
The shortcoming of prior art in view of the above, the purpose of this utility model is to solve the quantity-produced product in enormous quantities problems such as to occur when process monitoring and Stability survey that measurement equipment utilization factor is low, survey crew workload large and measurement result is deteriorated large.
For achieving the above object and other relevant objects, the utility model provides a kind of subsidiary frock of three-D measuring machine, comprise fixed head, several positive stop strips, keep away a frock, described fixed head is provided with the register pin of number row arrangement in matrix, every two positive stop strips one group are fixed on fixed head in orthogonal mode, a described frock of keeping away is rectangular parallelepiped, described in keep away a frock and be provided with positioning tool, described in keep away a frock the right-angle surface that forms against one group of positive stop strip of right-angle surface.
Preferably, described positive stop strip is screwed on described register pin, is arranged on the register pin of fixed head by positive stop strip according to actual conditions.
Preferably, described positioning tool is provided with stopper slot, and described positioning tool and a described frock of keeping away are by described stopper slot aligned contact.
Preferably, described fixed head and described positive stop strip are provided with smooth surface, and surface smoothness processing request is Ra0.25.
Preferably, the flatness of described fixed head is not more than 0.03mm.
Preferably, described fixed head and described positive stop strip adopt mould steel chromium material.
As mentioned above, the subsidiary frock of three-D measuring machine of the present utility model, has following beneficial effect: the utility model can be got a little automatically, ensures the unitarity of getting a position, can promote the Repeatability and Reproducibility of measurement result to greatest extent.Use frock coordinate, multi-work piece measures simultaneously, effectively promotes the utilization factor of three-D measuring machine, reduces the workload of survey crew simultaneously, reduce costs.Through practice find, the utility model measure frock produce beneficial effect have following some:
1. Repeatability and Reproducibility improve, by new and old measuring system MSA(measurement System Analysis) analyze Repeatability and Reproducibility be deteriorated some total variance ratio be reduced to 7.4% by 12.6%.
2. single products measures improved efficiency, and the Measuring Time of to save 30% than manual measurement measured automatically by 1 workpiece.
3. during batch detection, improved efficiency is obvious, measure 5 ~ 10 identical workpiece simultaneously, use this cover frock to set up frock coordinate system to measure, carry out than using workpiece coordinate piecemeal measuring the Measuring Time can saving 50%, the utilization factor improving equipment reduces cost of labor simultaneously.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the subsidiary frock of three-D measuring machine of the present utility model.
Element numbers illustrates:
1-fixed head, 11-register pin, 2-positive stop strip, 3-positioning tool, 4-keep away a frock, 5-band measurement products.
Embodiment
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar the content disclosed by this instructions can understand other advantages of the present utility model and effect easily.
Refer to Fig. 1.Notice, structure, ratio, size etc. that this instructions institute accompanying drawings illustrates, content all only in order to coordinate instructions to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the utility model can produce and the object that can reach, still all should drop on technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, quote in this instructions as " on ", D score, "left", "right", " centre " and " one " etc. term, also only for ease of understanding of describing, and be not used to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of the utility model.
As shown in Figure 1, the subsidiary frock of the three-D measuring machine that the utility model provides, comprise fixed head 1, several positive stop strips 2, keep away a frock 4, described fixed head 1 is provided with the register pin 11 of number row arrangement in matrix, every two positive stop strips 2 one groups are fixed on fixed head 1 in orthogonal mode, the described frock 4 of keeping away in rectangular shape, described in keep away a frock 4 and be provided with positioning tool 3, described in keep away a frock 4 the right-angle surface that forms against one group of positive stop strip 2 of right-angle surface.
As a kind of specific embodiment, positive stop strip 2 is screwed on described register pin 11, is arranged on the register pin 11 of fixed head 1 by positive stop strip 2 according to actual conditions.
As a kind of specific embodiment, positioning tool 3 is provided with stopper slot, and described positioning tool 3 and a described frock 4 of keeping away are by described stopper slot aligned contact.
