The described trailing flank vertically moving sleeve 8 is installed with a tooth bar 10 and for fixing the bolt of spring；Described spring 15 one end is fixed on this bolt, and the other end is fixed in top blind flange 16, for providing the elastic force of return for vertically moving sleeve 8.
Described gear 9 is arranged on rotating steadying bar 11 by rotating shaft 12, and gear 9 engages with tooth bar 10, and described rotating steadying bar 11 is fixed on vertical backup plate 6.
Joystick 13 is fixedly linked with rotating axle 12 by union joint 17 so that joystick 13 and rotation axle 12 coaxial rotation.Rotating axle 12 can rotate by driven gear 9, gear 9 engages with tooth bar 10, and then realizes tooth bar 10 drive and vertically move sleeve 8 entirety and move down.After after the external force acted on joystick 13 eliminates, under spring 15 acts on, vertically move sleeve 8 and reset.
The back side of vertical backup plate 6 is additionally provided with reinforcement, is used for fixing vertical backup plate 6.
The operation principle of above-mentioned porcelain stone powder prepressing units is:
Before precompressed, need first to be sequentially passed through sensor chip 26 front end by hand 29, two porcelain stone powder sheets 28 of long ceramic core and short ceramic core 27, then entirety is put in hexagonal matrix 24, is wholy placed in the precompressed on the fixing plate 1 of precompressed oxygen sensor afterwards in hexagonal groove 18 (note rotating depression bar and avoid chip).
Pin joystick 13 with hands afterwards, slowly press down, now under the effect of gear 9 and tooth bar 10, vertically move sleeve 8 and drive precompressed compressor arm 4 to move downward, somewhat make to defeat crackle ware stone powder sheet 28.After compacting, unclamping joystick 13, under the effect of spring 15, joystick automatically resets.
Described porcelain stone grain weight pressure unit, for thoroughly being pulverized by the porcelain stone powder sheet 28 in oxygen sensor, makes oxygen sensor internal structure compacting and sealing, after porcelain stone powder prepressing units is arranged on porcelain stone powder prepressing units, for porcelain stone powder sheet 28 is thoroughly pulverized.
Described porcelain stone grain weight pressure unit includes weight pedestal 201, the fixing plate 202 of weight oxygen sensor, main support plate 204, master plate 205, rack plate 206, weight cylinder 207, weight cylinder connector 208, depression bar union joint 209 and weight compressor arm 210.
The fixing plate 202 of weight oxygen sensor is fixedly mounted on weight pedestal 201, and the fixing plate 202 of weight oxygen sensor is provided with hexagonal groove 211 in the weight for clamping oxygen sensor 3, and the hexagonal pedestal 23 of oxygen sensor 3 is placed in weight in hexagonal groove 211.
Rack plate 206 is fixed on the platform set up by main support plate 204 and two master plates 205；Weight cylinder 207 is fixed on rack plate 206；Depression bar union joint 209 is arranged on the top of weight cylinder 207 piston rod by threaded engagement；Weight compressor arm 210 is arranged on depression bar union joint 209；Weight cylinder 207 is by the external controlled source of the gas of weight cylinder connector 208.
The distal center position of weight compressor arm 210 is provided with weight axial notch 212, the installation position of weight compressor arm 210 and oxygen sensor 3 should make: when weight compressor arm 210 moves downward, sensor chip 26 inserts in the weight axial notch 212 of weight compressor arm 210 just, and both do not contact.The setting of axial notch 210 makes compressor arm 204 both can avoid sensor chip 26, can touch again long ceramic core 29 and porcelain stone powder sheet 28.
The operation principle of above-mentioned porcelain stone grain weight pressure unit is:
