Abstract
The invention belongs to the technical field of air gauges, and particularly relates to a single-pipe flow type plane flatness measurement device for measuring flatness. The single-pipe flow type plane flatness measurement device comprises a base, a workbench and an air gauge assembly, wherein the workbench and the air gauge assembly are arranged on the base. The air gauge assembly is arranged at the portion, on one side of the workbench, of the base. An upright is arranged at the portion, on the other side of the workbench, of the base. The upright is provided with a height adjusting board with the adjustable height. A supporting board capable of sliding horizontally is arranged on the height adjusting board. A measuring head of the air gauge assembly is fixed to the supporting board and provided with multiple nozzles. A ventilation channel is formed in the measuring head and provided with an air distribution chamber which is communicated with all the nozzles through arranged auxiliary ventilation channels. The ventilation channel is connected with the air gauge assembly. The end face of the measuring head is parallel to the face of the workbench. The device is easy and convenient to operate and high in measurement accuracy.
Description
Technical field
The invention belongs to air-gauge technical field, be specifically related to the single tube flow formula plane Pingdu measurement mechanism of measurement plane degree.
Background technology
In mechanical manufacturing field, the flatness of workpiece is important Testing index, and the survey instrument of general closed planar degree is clearance gauge, clock gauge and three coordinate measuring machine, but these survey instrument complex operations are easy not.
Summary of the invention
Technical matters to be solved by this invention is for above-mentioned defect, provides easy and simple to handle, the single tube flow formula plane Pingdu measurement mechanism that measuring accuracy is high.
The technical solution used in the present invention is as follows:
Single tube flow formula plane Pingdu measurement mechanism, comprise base, the worktable that base is arranged, air-gauge assembly, described air-gauge assembly is arranged on the base of worktable side, the base of the other side of worktable is provided with column, column is provided with adjustable for heightly heightens plate, heightening that plate is provided with can the supporting plate of horizontal slip, supporting plate is fixed with the gauge head of air-gauge, described gauge head is provided with multiple nozzle, gauge head inside is provided with airway, airway is provided with sub-air chamber, sub-air chamber and each nozzle are all communicated with the secondary airway arranged, airway is connected with air-gauge assembly, gauge head end face is parallel with work top.
Described spray nozzle front end is concordant with gauge head end face.
Described airway is preferably connected with air hose with air-gauge.
The invention has the beneficial effects as follows: adopt such scheme, measured workpiece is placed on the table, work top is reference field, start air-gauge assembly, heighten plate and make gauge head end face and the tested end contact of workpiece, gauge head end face and tested plane closely sealed, the flow that each nozzle flows out from gauge head end face is zero, if measured workpiece air spots is capable, then gauge head end face only has any to contact with the tested plane of workpiece, a wedge-shaped crevice must be had between two planes to exist, on gauge head, the air of each nozzle just flows into air from this wedge-shaped crevice, its flow is directly proportional to plane parallelism error, so the error amount of the depth of parallelism can be reflected on air-gauge accurately, easy and simple to handle, and utilize supporting plate to slidably reciprocate, the many places of the tested plane of repetitive measurement workpiece, make measurement result more accurate.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.
Fig. 1 is schematic diagram of the present invention.
