Description
Technical field
The utility model relates to a kind of survey instrument, especially relates to a kind of structural improvement that processing site is measured the measurement slide calliper rule of processed gear and verification process equipment that is used for.
Background technology
In order accurately to measure, particularly in time measure and handle it at the workpiece processing scene, people have designed various survey instruments, and slide calliper rule are wherein widely used a kind of.Common slide calliper rule have easy to usely when the smooth object of surface measurements, and measuring accuracy is than characteristics such as height.But when measuring the object of special object or surface irregularity, common slide calliper rule are the purposes that can't reach accurate measurement.The difficulty of processed gear being measured at processing site is particularly outstanding, therefore, can't in time proofread and correct process equipment, thereby influence the crudy and the working (machining) efficiency of workpiece.For example, when the reference diameter of prototype gear, the card base of slide calliper rule can't enter between adjacent two teeth of gear, and therefore, this segment distance can't be measured to, and also just can't extrapolate the reference diameter of gear according to measured value.
In order to overcome above-mentioned defective, satisfy special measurement needs, someone has designed a kind of tip distance vernier caliper (CN88218226.9), mainly form by slip card base, main scale, secondary chi, auxiliary vernier, angle card base, utilize the angle card base to abut on the conical surface of measured workpiece around secondary chi plane of rotation, it is very little that the slip card base is measured the crown carpenters square as the installation base surface of measured workpiece, is suitable for the measurement of polytype bevel gear tip distance size.But this kind slide calliper rule still can not solve the accurate measurement of particular data that gear etc. is had the workpiece of convex-concave surface, can not realize that processing site is to the timely measurement of workpiece with to the timely adjustment of process equipment.And structure is comparatively complicated, the cost of manufacture height, and complicated operating process, the precision of measurement also are difficult to be protected.On the other hand, the slide calliper rule of such scheme have carried out significantly changing to the slide calliper rule that generally use at present, can't utilize existing common slide calliper rule to realize the purpose of the measurement of special workpiece.
Summary of the invention
Fundamental purpose of the present utility model provides a kind of simple in structure, the measuring accuracy height, it is very convenient to operate, can accurately measure at processing site the specific workpiece size that the reference diameter of gear etc. has a convex-concave surface, and then the measurement slide calliper rule that can in time adjust process equipment; Solved the existing in prior technology complex structure, measuring accuracy is not high, manipulate comparatively loaded down with trivial details, the technical matters that can't be difficult to accurately measure etc. to the size of specific workpiece at processing site with convex-concave surface.
The utility model also has a purpose to provide a kind of improvement of being convenient to, and can effectively utilize existing common slide calliper rule, and slide calliper rule are measured in Installation and Debugging very easily; Solve existing in prior technology the slide calliper rule that generally use have at present been carried out significantly changing, can't utilize existing common slide calliper rule to realize the technical matters of the measurement purpose etc. of special workpiece.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: measure slide calliper rule, comprise the chi frame, be installed in the blade that has scale on the chi frame, on the chi frame, be provided with a fixedly card base, be provided with a movable card base in the outer end of blade, it is characterized in that, be fixed with a measuring head on the described movable card base, be fixed with another measuring head on the described fixedly card base, two above-mentioned measuring heads are all tapered.
The utility model has creatively been installed measuring head on the card base of common slide calliper rule, because measuring head is tapered, can embeds in the depression of concavo-convex workpiece, thereby measure size exactly.The shape of measuring head preferably can adapt with the concave shape of workpiece, thereby further improves the precision of measuring.So just can measure workpiece, and in time process equipment be adjusted at processing site.
As preferably, two above-mentioned measuring heads respectively by screw retention at movable card base with fixedly on the card base.Can easily measuring head be installed to movable card base and fixedly on the card base, make common slide calliper rule have the function of measuring the special workpiece size by screw.In addition, according to different workpiece, also can change different measuring heads.
As another kind of scheme, two above-mentioned measuring heads respectively with movable card base and fixedly card base be made as one.
As preferably, described two measuring heads are provided with fixedly card base is vertical with movable card base respectively, and the head of two measuring heads is mutually opposed.
As preferably, the head of described measuring head is spherical in shape.When the reference diameter of prototype gear, the reading of slide calliper rule is not directly to be tested gear compound graduation circular diameter.To take distinct methods to convert according to the difference of the shape of measuring head head and just can draw the reference diameter of tested gear.If the measuring head head is spherical, then the calibration diameter of a circle deducts spherical diameter for the slide calliper rule reading.
As preferably, described chi frame is provided with the digital display screen that is used to show measurement data, and digital display screen and metering circuit link.
Therefore, the utlity model has following advantage: 1. simple in structure, the measuring accuracy height, it is very convenient to operate, can accurately measure at processing site, and can in time adjust process equipment to the specific workpiece size that reference diameter of gear etc. has a convex-concave surface.2. be convenient to improve, can effectively utilize existing common slide calliper rule, Installation and Debugging are very convenient.3. cost of manufacture is cheap, and is applied widely, is easy to apply.
