For achieving the above object and other relevant objects, the utility model provides a kind of vernier caliper, comprise main scale, main scale end is provided with determines fastener, and main scale is provided with sliding shoe, and sliding shoe is provided with slip fastener, slip fastener with determine fastener and coordinate clamping to be detected size, the mating surface determining fastener and slip fastener is provided with the first notch, and slip fastener is provided with the second notch with the mating surface determining fastener, and the first notch is equal with the second width of rebate.The setting of notch, is convenient to determine fastener and slip fastener walks around projection, is clamped in the structure that needs to measure, completes accurate measurement.
As preferably, the first notch of vernier caliper is identical with the second depth of rebate.
As preferably, the sliding shoe of vernier caliper is electronic display, reduces the error of artificial reading, raises the efficiency.
As preferably, the display screen of vernier caliper is greater than the width near determining fastener side away from the width determining fastener side.
As preferably, the display screen of vernier caliper is provided with detent mechanism away from determining fastener side, and described detent mechanism coordinates with main scale.
The utility model additionally provides a kind of radiator water chamber ca(u)lk technique,
Comprise the steps:
1) agent of core body main piece slot welding, is cleared up;
2), equipment point-detecting: the core body needed for spot check, O-ring seal and hydroecium;
3), O-ring seal is embedded core body main piece groove;
4), hydroecium is embedded in core body main piece groove;
5), ca(u)lk, roll rear O-ring seal and load in hydroecium main leaf groove completely;
6), ca(u)lk is measured.
As preferably, detect the method for O-ring seal in step 1, confirm O-ring seal whether distortion before assembling, the contact of O RunddichtringO two ends must put in place by both hands, confirms whether O RunddichtringO has twisted phenomena; Can not use when there is distortion.
As preferably, the compressibility of the O-ring seal after ca(u)lk is at 30%-50%.
After ca(u)lk completes, the fastener of determining of vernier caliper is put into slotted eye, slip slip fastener, to hydroecium ca(u)lk inwall, detent mechanism is fixed sliding shoe, arranging of notch can make the fastener of determining of slide calliper rule accurately touch slotted eye surface, and thickness shows on the electronic display screen, according to data, test personnel can judge that whether this ca(u)lk is qualified.
As mentioned above, the utility model has following beneficial effect: carried out hand inspection to O-ring seal before assembling, reduce the underproof risk of assembling, after ca(u)lk completes, the fastener of determining of vernier caliper is put into slotted eye, slip slip fastener, to hydroecium ca(u)lk inwall, detent mechanism is fixed sliding shoe, arranging of notch can make the fastener of determining of slide calliper rule accurately touch slotted eye surface, thickness shows on the electronic display screen, according to data, test personnel can judge that whether this ca(u)lk is qualified, avoid people for causing erroneous judgement by data, thus make the connection of hydroecium and radiator centre more reliable, product quality is improved.
