Description
Technical field
The present invention relates to a kind of in engine manufacture process, can realize automatically to device and the control method thereof of processing residual scrap iron cleaning in cross bore.
Background technology
Engine has much elongated (8 and following) cross bore in the fabrication process, and mainly concentrates in cylinder cap and cylinder body, and these cross bore may be used for logical machine oil or cooling water.Due to impacts such as the authenticity of technological parameter, tool length, breakings, the problems such as iron filings are piled up, oilhole is obstructed may be there is in above-mentioned cross bore in process.In current production process, the mode manually relying on frock to detect, use air gun to blow mainly is taked to detect and remove.This detection mode is in the machining process of whole engine, and not only efficiency is low, and staff labor intensity is large, and affects site environment, is unfavorable for that the beat of whole production line promotes.In addition in manual operation process, also easily occur undetected or detect a series of uncontrollable factors such as error.Also there is its relative special-purpose equipment to realize this function at home and abroad, but special lathe or cost high cost transformation existing equipment must be increased, invest relatively high, be difficult to popularize.
Summary of the invention
The object of the invention is to propose a kind of structure is simple, cost is low, automaticity is high engine cross bore scrap iron removing apparatus and control method thereof.
Engine cross bore scrap iron removing apparatus of the present invention comprises a through probe, and one end of described probe is connected with air machinery by tracheae; Pressure sensor is provided with between described probe and air machinery; Described probe is fixed on the driving mechanism of a linearly movement, described air machinery, driving mechanism, pressure sensor are all connected with a control unit, described control unit receives the signal of pressure sensor, and controls the work of air machinery, driving mechanism.
The control method of above-mentioned engine cross bore scrap iron removing apparatus is as follows:
A: after workpiece is in place, send signal by control unit and control driving mechanism, it is made to drive probe to move towards the cross bore of workpiece, while probe enters cross bore, control unit opens air machinery, utilize air machinery to probe compressed gas supplying, this Compressed Gas is blown in cross bore by probe, simultaneously pressure sensor Real-Time Monitoring air pressure;
B: according to design, if cross bore is through, air pressure then detected by pressure sensor should (specifically be determined by the bleed pressure of air machinery and the diameter of cross bore) within the specific limits, if the air pressure that pressure sensor detects is greater than predetermined pressure, then represent that the situation of some or all of blocking appears in cross bore; When control unit finds that the air pressure signal of pressure sensor is greater than preset range, control unit controls driving mechanism and stops mobile, and keeps the operation of air machinery, blows continuously in cross bore, to blow away iron filings residual in cross bore;
C: after the unobstructed improving situation of cross bore, the air pressure detected by pressure sensor can diminish thereupon, and when control unit finds that the air pressure signal of pressure sensor is in preset range, control unit controls driving mechanism and continues mobile;
D: repeat B, step C, until cross bore is all unimpeded, and the shift motion of driving mechanism meets predetermined stroke (namely probe arrives at the bottom of cross bore), control unit controls driving mechanism oppositely movement, to make probe shift out cross bore, completes scrap iron removing operation.
Further, in the step B, control unit, after driving mechanism stops the time of movement to exceed scheduled time length, carry out alarm, now show that cross bore fails to be processed into through hole, or the residue in cross bore cannot blow out, must manual intervention.
Further, described driving mechanism is straight line cylinder, and described probe is fixed on the piston rod of straight line cylinder by probe support; The end of described piston rod is also fixed with an auxiliary inflatable device be made up of magnetic valve and auxiliary blow gun, and described auxiliary inflatable device is connected with described air machinery by tracheae, and the magnetic valve of described auxiliary inflatable device is connected with described control unit.In described D step, when the shift motion of driving mechanism meets predetermined stroke, first control unit controls driving mechanism and stops mobile, and the magnetic valve controlling auxiliary inflatable device is opened, auxiliary blow gun is utilized to blow the scheduled time to the bottom outlet of cross bore, and then close the magnetic valve of auxiliary inflatable device, and control driving mechanism oppositely movement, not residual scrap iron can be guaranteed in cross bore like this.
Further, described probe is socketed to form by probe bodies and protection tube, is provided with spring between described probe bodies and protection tube, and described spring is placed in probe bodies, and one end of spring and probe bodies are fixed, and the other end and protection tube are fixed.Like this when probe bodies touches the bottom of cross bore, its impulsive force be subject to can absorb by spring, thus avoid probe bodies damage by impulsive force.
Further, the sidepiece of described probe is provided with groove, and in such iron filings and cross bore, impurity is discharged by this groove, and another hole also by cross bore is discharged, and improves the degree of convenience that iron filings are discharged.
Further; described probe bodies is made up of canned paragraph, fixed block and probe wireway, and described probe wireway is installed on canned paragraph by fixed block, and described spring is placed on the canned paragraph of probe bodies; and the canned paragraph of one end of spring and probe bodies is fixed, the other end and protection tube are fixed.After damage appears in probe wireway, can only change probe wireway, to reduce maintenance cost.
Further, be also connected with air accumulator, pressure regulator valve, adjustable throttling in turn between described air machinery and probe, described pressure sensor is connected between pressure regulator valve and adjustable throttling by branched pipe.Air accumulator can ensure the stability of source of the gas, when bleed pressure is excessive, and the bleed pressure that air accumulator Absorbable rod is certain, when bleed pressure is too small, the air release of storage can be gone out by air accumulator, and then ensures the stability of input gas pressure; Pressure regulator valve, adjustable throttling combine, and can control the pressure of probe ejection gas, thus the original air pressure that pressure sensor is detected (air pressure namely in the unimpeded situation of cross bore) meet the requirements.
