Abstract
The utility model provides an angle measuring device of a trapezoidal piston ring. The angle measuring device is mainly composed of a device support, a device cantilever frame, a fastening and fixing element and a standard dial indicator, and a micrometer caliper. The device support is used for connecting and supporting other components of the device; the device cantilever frame is used for supporting and fixing the dial indicator, and rotates in a certain angle range so as to perform appropriate position adjustment; the dial indicator and the micrometer caliper respectively measure the vertical distance and the horizontal distance of a trapezoidal corner of the trapezoidal piston ring; and therefore, the quality of products can be monitored indirectly. The angle measuring device has the advantages of simple and compact structure, convenient operation, high degree of standardization, accurate and reliable detection, high measurement accuracy, great consistency in measurement results, and low manufacturing cost of special equipment, and can be extensively popularized in and applied to engine trapezoidal piston ring angle measuring field.
Description
Technical field
The utility model relates to a kind of trapezoidal angular measurement frock technical field servicing unit of engine keystone-type piston ring, and the trapezoidal angle that especially realizes the engine keystone-type piston ring is measurement mechanism quick and precisely.
Background technology
Keystone-type piston ring can prevent the bonding of piston ring, is widely used in aeromotor and diesel engine.The key dimension parameter of keystone-type piston ring has: nominal diameter, and radial thickness, keystone ring height and trapezoidal angle, the angle measurement unit of visible keystone-type piston ring is one of indispensable special tooling of process of producing product.A kind of Novel angle measurement mechanism of keystone-type piston ring comprises appliance stand and device cantilever shalving etc.
At present, the use direct method of measurement (as: universal protractor, optical measuring instrument, circular dividing table etc.) that the trapezoidal angular measurement of existing keystone-type piston ring has, but in some cases, can not use direct measuring method or measurement not to reach the measuring accuracy requirement; Some use indirect methods of measurement, as from the controlling angle calliper, control accuracy is relatively poor, as the Special precision device of belt sensor, guide rail, precision lead screw, stepper motor etc., but its complex structure, operating difficulties, manufacturing cost is high, and fund input is higher.
Summary of the invention
In order to overcome the inefficiency of the measurement of angle quality control that has keystone-type piston ring now, the angle-measurement accuracy of keystone-type piston ring is not high enough, the high deficiency of special-purpose angle measurement unit manufacturing cost, the utility model provides a kind of Novel angle measurement mechanism of keystone-type piston ring.The technical solution that its technical matters that specifically solves the utility model adopts is: a kind of angle measurement unit of keystone-type piston ring, comprise appliance stand 11, and appliance stand 11 can be placed directly on required worktable; Device cantilever shalving 2, device cantilever shalving 12 is tightened on appliance stand 11 by holding screw 13.
Appliance stand 11 upper screwed hole 11-1 are used for measuring required micrometer caliper and are tightened to appliance stand 11.On device cantilever shalving 12, through hole 12-1 is tightened to device cantilever shalving 12 for measuring required clock gauge.
In appliance stand, can be placed directly on required worktable; In the device cantilever shalving, be tightened on appliance stand by holding screw 3, belong to indirect measurement method, be able to use parts few, the simple purpose of parts manufacturing process.On the appliance stand upper screwed hole, be used for to measure required micrometer caliper and be tightened to appliance stand, on through hole on the device cantilever shalving, be used for to measure required clock gauge and be tightened to the device cantilever shalving, by clock gauge and micrometer caliper, thereby be able to the high realization of measuring accuracy to the purpose of effective control at the trapezoidal angle of keystone-type piston ring.
The beneficial effects of the utility model are, the measuring principle of a kind of Novel angle measurement mechanism of this practical keystone-type piston ring is simple, easy to operate, and the low cost of manufacture of equipment can access extensive promotion and application.

Fig. 2 is the utility model master left view,
Fig. 3 is the utility model vertical view.
11. appliance stands in figure, the threaded hole on the 11-1. appliance stand, 12. device cantilever shalvings, the through hole of 12-1. device cantilever shalving, 13. holding screws.
Embodiment
Referring to accompanying drawing, a kind of Novel angle measurement mechanism of keystone-type piston ring comprises appliance stand 11 and device cantilever shalving 12.
Appliance stand 11, one side connects other parts of this Novel angle measurement mechanism, can be placed on different worktable on the other hand.
Device cantilever shalving 12, one ends are fixed on appliance stand 11 by holding screw 13 and (annotate: can rotate in the certain angle scope and adjust), and the other end is split into U-shaped groove, in order to the clock gauge of the trapezoidal vertical range of fixation measuring.
The process of surveying instrument in a kind of Novel angle measurement mechanism of keystone-type piston ring: with qualified micrometer caliper, be fixed by the threaded hole 11-1 on appliance stand 11; With qualified clock gauge, be fixed by U-shaped groove and the through hole 12-1 that installs cantilever shalving 12.
a kind of Novel angle measurement mechanism measuring process of keystone-type piston ring: qualified keystone-type piston ring is placed into the micrometer caliper measured place, adjust the opening of micrometer caliper, make keystone-type piston ring naturally be stuck in the micrometer caliper measured place, adjustment clock gauge position, obtain keystone-type piston ring from the thickness of micrometer caliper measured place maximum gauge, this thickness is as the reference value, again keystone-type piston ring to be measured is positioned over naturally the micrometer caliper measured place, observe the reading variation range of clock gauge, whether drop in margin tolerance, if in margin tolerance, measured keystone-type piston ring is qualified, otherwise defective.
