Abstract
The invention discloses a crankshaft static balance detecting digital display device, which relates to a crankshaft static balance detecting device. A lever bracket is characterized in that identical axis line through holes are arranged on two side plates of a U-shaped plate at the upper end tip of a support rod of a base, a pin shaft passes through a round hole at the middle part of a transverse lever to be fixed in the two through holes of the U-shaped plate, two ends of the transverse lever are provided with a longitudinal hole respectively, two end tips of the transverse lever are provided with threaded holes, the threaded hole at one side is communicated with the longitudinal hole at this side, a force transferring round rod and a force detecting round rod are respectively sleeved, in a movable fit manner, in the two longitudinal holes of the transverse lever and then bolted; the position of the bottom surface of the force transferring round rod is a planar position of excircle vertex of an eccentric shaft when the axis line of the eccentric shaft of a crankshaft is positioned on the same horizontal plane as the axis line of a basic shaft in case that the crankshaft is placed on a detection bracket, and the position of the bottom surface of the force detecting round rod is a contact position of the upper surface of a scale pan under zero critical state of an electronic scale. The device has the advantages that: upward action force of the eccentric shaft is reflected by digital display data of the electronic scale through a lever device in one step, static balance detecting data is obtained by means of torque conversion, operation is simplified and working efficiency is high.
Description
Technical field:
The present invention 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 objective of the invention is to overcome above-mentioned defective, provide a kind of bent axle static equilibrium to detect digital display device.
The solution of the present invention 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.
The invention has the advantages that: 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.

Fig. 2 is the A-A cut-open view of Fig. 1.
Fig. 3 is a prior art pick-up unit structural representation.
Embodiment:
The present invention includes and detect 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.
