Abstract
The utility model provides a digital display device for crankshaft static balance detection, relating to a device for crankshaft static balance detection. A lever bracket is provided with coaxial line through holes on the two side plates of a U-shaped plate on the upper end of an upper supporting rod on a pedestal, a pin passes through a circular hole on the middle portion of a horizontal level, and fixed on the two through holes of the U-shaped plate, the two ends of the horizontal level are provided with a longitudinal hole, respectively, the two ends of the horizontal level are equipped with screwed holes, one screwed hole is communicated with a longitudinal hole on the same side, force receiving round bars, force measuring round bars are respectively nested into the two longitudinal holes on the horizontal level by movable fit and then fixed by bolts; the position of the bottom surface of the force receiving round bar is the plane position of the highest point of an excircle of an eccentric shaft when a crankshaft is placed on a detection bracket, and the shaft axis of the eccentric shaft is in the same plane as that of the shaft axis of a basic shaft, the position of the bottom surface of the force measuring round rod is the contact position of the upper surface of a scale pan when an electronic scale is in zero critical state. The advantages lie in that the upward applied force is reflected on the digital display data of the electronic scale by the lever device at one time, static balance detection data is obtained by moment conversion, the operation is simplified and the working efficiency is high.
Description
Technical field:
The utility model relates to the bent axle static balance testing device.
Background technology:
Crankshaft structure is that bent axle is formed by two weighted cam discoid body disjunctors by two outside standard shafts and middle excentric shaft.Whether after standard shaft and the excentric shaft car system, must detect bent axle and do static equilibrium and exceed standard, it is that two standard shaft with bent axle is placed on and observes counterweight on the double supporting wheel that detects the carriage two ends and detect that bent axle static equilibrium at present detects.Detecting carrier structure is to be respectively arranged with the double supporting wheel structure on the frame both walls, one-sided two supporting-roller shaft two axial ends are linked on the bearing of the monolateral both walls of frame location, each fixes a support roller each supporting-roller shaft, one-sided two support rollers are axial, adjacent dislocation and radial component overlap condition, four support roller equal diameters, the supporting-roller shaft coaxial inner conductor of frame both sides correspondence.
Monolateral standard shaft is placed on one-sided two support rollers and overlaps in the groove shape space that forms, and standard shaft owing to lay particular stress on rotates freely, and support roller also can rotate thereupon, makes the standard shaft rotation be free non-resistance state and is convenient to detect.After two standard shafts are placed on the double supporting wheel of both sides, bent axle cam disc, excentric shaft are if not reaching static equilibrium then produces rotation, and lighter upwards commentaries on classics of excentric shaft one side are generally speaking changeed under cam disc great circle one side direction, the deviation of setting when this is design is beneficial to the subsequent handling correction.This moment will be on excentric shaft the fit balancing weight, balancing weight is that two semicircular ring are closed up on the excentric shaft cylindrical, because the static equilibrium error is not fix a number, so balancing weight weight will have the some assembly pouring weights that go forward one by one gradually, one group of group is installed, is dismantled and carry out repeatedly can realizing statically balanced balancing weight until finding, again balancing weight is placed on the electronic scales weighing and draws data and just calculate to detect and finish, so that subsequent handling is handled according to detecting data.So the operation repeatability is big, and work efficiency is low.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned defective, provides a kind of bent axle static equilibrium to detect digital display device.
Scheme of the present utility model is: comprise the detection carriage, it is characterized in that: also be provided with leverage, electronic scales, leverage is made up of lever bracket, horizontal lever; Lever bracket is that base upper support bar upper end U-shaped plate biside plate is provided with the coaxial inner conductor through hole, a bearing pin passes horizontal lever middle part circular hole and is fixed in two through holes of U-shaped plate, pin diameter is less than horizontal lever middle part circular hole, laterally lever two is respectively arranged with a vertical hole, laterally be respectively arranged with the horizontal thread hole on the lever two ends end face, one-sided threaded hole is communicated with the vertical hole of this side, after laterally being inserted in relay round bar, dynamometry round bar movingly respectively on two vertical holes of lever, being screwed in the horizontal thread hole with bolt and implementing fixing; Relay round bar basal surface position is for being placed on detection excentric shaft cylindrical peak planimetric position during the same surface level state of its excentric shaft axial line and standard shaft axial line during carriage, scale pan upper surface contact position when dynamometry round bar basal surface position is electronic scales zero-bit critical conditions when bent axle.
Advantage of the present utility model is: by leverage is disposable the excentric shaft acting force that makes progress is reflected on the electronic scales digital display data, converting by moment directly obtains static equilibrium and detects data, simplified control work efficiency height.

Embodiment:
The utility model comprises detection carriage 1, it is characterized in that: also be provided with leverage, electronic scales 8, leverage is made up of lever bracket 6, horizontal lever 4; Lever bracket 6 is provided with the coaxial inner conductor through hole for base upper support bar upper end U-shaped plate biside plate, a bearing pin passes horizontal lever 4 middle part circular holes and is fixed in two through holes of U-shaped plate, pin diameter is less than horizontal lever 4 middle part circular holes, laterally lever 4 two are respectively arranged with a vertical hole, laterally be respectively arranged with the horizontal thread hole on the lever 4 two ends end faces, one-sided threaded hole is communicated with the vertical hole of this side, after laterally being inserted in relay round bar 3, dynamometry round bar 7 movingly respectively on 4 two vertical holes of lever, being screwed in the horizontal thread hole with bolt and implementing fixing; Relay round bar 3 basal surface positions are for being placed on detection excentric shaft 5 cylindrical peak planimetric positions during the same surface level state of its excentric shaft 5 axial lines and standard shaft 2 axial lines during carriage 1, scale pan upper surface contact position when dynamometry round bar 7 basal surface positions are electronic scales 8 zero-bit critical conditionss when bent axle.
Use bolt after relay round bar 3, dynamometry round bar 7 adjustable height, bent axle for different eccentric throws, different standard shaft 2, excentric shaft 5 diameters detects, excentric shaft 5 cylindrical peak planimetric positions are foundation during with the same surface level state of excentric shaft 5 axial lines and standard shaft 2 axial lines, can the adjustment (adjusting) lever setting position, two round bar bottom surface height, just can implement to detect.
Because excentric shaft 5 one sides of setting are light, so always going up pendulum, excentric shaft 5 touches relay round bar 3 bottom surfaces, electronic scales 8 just be data show.
