Description
Technical Field
The utility model relates to a detect anchor clamps of measurationing that chamfer was used, especially require higher product to drill way chamfer, can be quick, accurate measure the accurate interior drill way chamfer measurement anchor clamps of measuring of chamfer actual dimension.
Background
The chamfering of orifices has different requirements due to their different functions and functions. The chamfering process is often regarded as an auxiliary process in the process design and is ignored by the process designer. Such a deviation in recognition causes the chamfering process to be in a standstill state for a long time. In high-end products of aerospace military industry, some precision mechanical parts have high quality requirements on chamfers, particularly the shaft hole chamfer quality requirements of gears are high, the machining of the hole opening not only requires deburring, but also has high precision requirements on angles and edge widths, and even requires that the chamfer reference end face of a part must be machined or very flat, burrs and flashes cannot be formed between the chamfer reference end face of the part and the chamfer inclined face, and the requirements on size precision, shape precision and position precision are high. When the chamfering angle is small, the small change of the chamfering angle can cause the change of the height dimension of a large chamfer, and the common inner hole chamfering tool cannot meet the requirement, which is always a difficult problem. The conventional machining chamfer dimension has a larger error with the chamfer dimension marked by the engineering drawing, and the design requirement or the use requirement cannot be completely met. With the development of production and science and technology, people put forward higher and higher requirements on the quality of engineering surfaces, and surface measurement and evaluation methods are developed constantly and gradually. In order to guarantee the quality and the service life of parts, some precision inner holes are often marked with chamfering requirements, and more products make extremely strict requirements on the size difference of the two ends of the hole: and (4) chamfering and deburring the workpiece difficult to be machined by precise chamfering. Such as: the oil, gas and electric valves for aviation, military industry and automobile industry, engine cylinder bodies, cylinders, ball through holes, inner wall holes and bearing mounting holes have high chamfering difficulty, orifice chamfering precision requirement is high, and the difference of the chamfering sizes of two ends must be controlled within 0.05. The requirements on the depth of orifice chamfers such as various inner chamfers, outer chamfers, crossed hole chamfers, end orifice chamfers, flange hole front and back chamfers and the like are high, the clamping is not easy, and whether accurate direct measurement is carried out on chamfer workpieces in various forms can directly influence the overall performance and the service life of a product. If holes are made in the same part, at different planes, and these are through holes, then cross holes are formed. Cross holes are present in many workpieces, for example: valve body, hydraulic pump, filter, cylinder head, etc. In the process of machining the cross holes, burrs are easily formed at the intersecting parts of the two holes, and the burrs exist in the parts, so that the burrs are difficult to remove cleanly. The traditional cutter can not be used for chamfering the inner and outer hole walls of a double-sided cylinder and various valve body holes, particularly small hole walls, and the measurement of burrs and chamfers is very difficult. At present, the basic detection means is that a projector detects the diameter of a chamfer, and is also a more accurate mode; however, the method has large investment and low efficiency, and cannot be immediately inspected on site; other methods are basically visual inspection, rough caliper measurement, and the error is very large because caliper measurement cannot be centered.
At present, the surface quality, especially the surface roughness, is mostly measured by a diamond contact pin in a contact mode, the inevitable abrasion of the contact pin can influence the measurement result, and the like. The non-contact measurement method does not cause scratches and deformation, but is greatly influenced by the optical performance of the material, the installation of the workpiece, the inclination degree and environmental factors, and the use of the method is limited to a certain extent. Although this measurement method is reliable, requires low environmental conditions and is relatively inexpensive to measure, it has the disadvantage that the sharp stylus used can scratch the workpiece. The cutter is flexible to stretch and retract in the using process, enough pressure is ensured during cutting, and the cutting angle size exceeding the requirement can be caused if the machining time is too long and the material is different. The blade cannot extend into the small hole due to overlarge force; the pressure is too low to bear the cutting force during chamfering, and the chamfering task cannot be finished. If lean on artifical with scraper, file chamfer, the aperture is little, and the chamfer operation degree of difficulty that requires highly to interior drill way precision is big, and not only the chamfer quality is difficult to guarantee, and production efficiency is low moreover, and the chamfer process often becomes the bottleneck that influences production.
At present, various measuring instruments can measure whether the chamfer size at the position is qualified according to the standard, such as: three-coordinate, imager, go-no end plug gauge, etc., but none of these measurement methods is efficient or accurate in measuring the actual value of the chamfer size. Although the three-coordinate detection equipment can accurately measure the actual value of the size of the chamfer, in actual production, if each chamfer is measured by adopting three coordinates, a large amount of three-coordinate resources are occupied, and the detection time of other products is delayed; meanwhile, if the size difference of the chamfer is detected to be unqualified, the resetting performance of the re-repairing processing is poor, the re-aligning processing is needed, a large amount of production time is delayed, even the aligning is not accurate, the part is scrapped, and the production cost is increased. The imager can also detect the actual value of the size of the orifice chamfer, but during measurement, the burr at the orifice chamfer has a large influence on the measured value, so that the measurement result is inaccurate, if the burr at the chamfer is removed and then the measurement is carried out, the chamfer sharp edge is too smooth, the visual judgment of a person is influenced, the technical requirement on measuring personnel is high, the measurement result is inaccurate, and the measurement efficiency is low; meanwhile, as the measurement time goes on, the energy of the measuring personnel is tired, the fluctuation of the measurement result is increased, qualified parts are judged to be unqualified, unqualified parts are judged to be qualified, the economic loss is caused, and more serious the product quality is unqualified, so that potential safety hazards are caused, and even the machine is damaged and people die. And the use is passed through and is stopped the end plug gauge and measure, can only guarantee whether chamfer is qualified everywhere, can't measure the actual value of chamfer size, can't contrast out the difference of both ends chamfer size, and some products do not make the requirement to the difference of both ends chamfer size, if measure with this method and deliver, probably in the in-service use, because the asymmetry of chamfer, cause the piece mill of part drill way both ends, influence product life-span, cause economic and reputation's dual loss. There is a need for a measurement method that can quickly and accurately measure the actual value of the chamfer dimension of the orifice to meet the problem in production.
