Abstract
A central positioning system for detecting circle runout of a grinding wheel comprises a spring clamp clamping component and a driving device, wherein the driving device comprises a spindle seat; a spindle is arranged in the spindle seat; a transmission piece is arranged at the tail part of the spindle; the spring clamp clamping component comprises an air claw, a coupling flange and an air pipe; the air claw is connected with the top of the spindle through the coupling flange, and the lower end of the air claw is connected with the air pipe; and a grinding wheel positioning device is arranged at the top of the spindle. Compared with the prior art, the central positioning system has the advantages that a motor is adopted to drive the grinding wheel to rotate, thereby saving more labor than manual pushing, and has higher efficiency and avoids influences on a detection result from uncontrollable factors produced during manual driving; and the air claw positioned accurately and a positioning ring structure with a rolling body are adopted, so as to achieve the effect of satisfying the detection of circle runout of the grinding wheel with a simple system structure.
Description
Technical field
The invention belongs to extraordinary emery wheel circular runout detection technique field, relate in particular to the centralized positioning system that is used to detect the thick and heavy parallel grinding wheel circular runout of major diameter.
Background technology
Circular runout is an important technology index of emery wheel, and as the machining tool of a kind of high speed rotation, in order to guarantee the safety of operator and equipment, circular runout is one of emery wheel Interventions Requested when dispatching from the factory, and the emery wheel circle instrument of beating is adopted in the check of circular runout.Mode according to conventional detection emery wheel circular runout, the most general to resin abrasive cutting wheel and cymbals shape emery wheel detection circular runout, the instrument that detects at present usefulness only has JS/PT-600 disc wheel end face run-out instrument that Zhengzhou Abrasive Materials, Abrasive Tools, Grinding Inst. (CN) No.1 Huashan R produces, and it can detect the maximum gauge 600mm of emery wheel, the maximum weight 6kg of emery wheel, its detection method is: tested emery wheel is enclosed within JS/PT-600 circle beats and can realize the detection of emery wheel circular runout on the tapered sleeve in the suitable emery wheel aperture that instrument is equipped with, do not need to clamp emery wheel with jig and carry out centralized positioning.Its weak point is to decide the maximum carrying of the tapered sleeve 6kg at emery wheel center, and suitable maximum grinding wheel diameter is 600mm.And for the thick and heavy parallel grinding wheel of major diameter as resin heavy load grinding emery wheel, maximum gauge is greater than 750mm, weight reaches more than the 100kg, detect the round instrument of beating of JS/PT-600 of resin abrasive cutting wheel circular runout, can't realize detection heavy load abrasive grinding wheel uniform thickness heavy sand wheel circular runout.
Summary of the invention
Technical problem to be solved by this invention is in order to improve the accuracy of detection of thick and heavy emery wheel circular runout, a kind of centralized positioning system that is used to detect the emery wheel circular runout to be provided.
In order to solve the problems of the technologies described above by the following technical solutions: a kind of centralized positioning system that is used to detect the emery wheel circular runout, comprise spring jig clamping part and drive unit, described drive unit comprises spindle drum, and main shaft is arranged in the spindle drum, and the main shaft afterbody is provided with driving member; Spring jig clamping part comprises gas pawl, terminal pad and tracheae, and the gas pawl is connected the main shaft top by terminal pad, and gas pawl lower end connects tracheae; The main shaft top is provided with the emery wheel positioner.
The main shaft two ends are arranged in the spindle drum by bearing and by the locking nut location, the main shaft bottom is fixed by bearing gland.
The main shaft axial centre is provided with air pipe passway, and tracheae is arranged in the air pipe passway.
Described emery wheel positioner comprises that connection main shaft top at the benchmark locating ring, is provided with rolling element and plane locating ring above the benchmark locating ring, and rolling element is between plane positioning ring and benchmark locating ring.
The present invention has compared with prior art adopted the motor-driven emery wheel to rotate, and than more laborsaving with the hand propelled emery wheel, efficient is higher, has also avoided the influence to testing result of the uncontrollable factor that produces in the manual drives process; Adopted and located accurate gas pawl and have the locating ring structure of rolling element, satisfied the effect that thick and heavy emery wheel circular runout detects thereby reach with simple system structure.And the centralized positioning systematic technical indicator of this emery wheel circular runout meets the specification requirement of the round run-out tolerance of industry national standard requirement smaller or equal to 0.3mm.
