Specific embodiment
Referring to accompanying drawing, a kind of rack-and-pinion cylinder self-locking hydraulic press for being provided with buffer gear, including：Housing 11, rack-and-pinion
Cylinder, toggle, limitation locking device, buffer gear；
Rack-and-pinion cylinder includes：Cylinder body 15, the tooth bar 17 being coaxially located in cylinder body 15 nibble merga pass lubrication with tooth bar 17
Axle sleeve 9 is sleeved on the bent axle 12 in housing 11, is located at the piston 18 at 17 two ends of tooth bar, and cylinder body 15 and piston 18 are sealed
Sealing member 16, be located at the venting plug 22 at 15 two ends of cylinder body；After the injection hydraulic oil in cylinder body 15, piston 18 is promoted to drive tooth
Bar 17 is moved in cylinder body 15, and then band dynamic crankshaft 12 is rotated；
Toggle includes：The crank 8 being fixed on bent axle 12, lower end are hinged on the connecting rod 7 on crank 8, pass through
Bearing pin 6 is connected to the pull bar 1 of 7 upper end of connecting rod, is located at passive support ring 3 between pull bar 1 and housing 11, apical ring 5 with
And the sealing ring 4 sealed between support ring 3 and apical ring 5；The rotation of bent axle 12 is converted to by toggle
Pull bar 1 pumps；
Limitation locking device includes：The spacer pin 13 being screwed onto on housing 11, the locking being plugged in 11 preformed hole of housing
Pin 14；When bent axle 12 goes to top dead-centre, by spacer pin 13 bent axle 12 is carried out left side it is spacing, preformed hole insert stop pin 14
Right side is carried out to bent axle 12 spacing, make bent axle 12 that locking is realized in top dead-centre, it is to avoid shaken because of jolting or maloperation makes tooth
Wheel rack cylinder self-locking hydraulic press unblock；
Buffer gear is located on the outside of piston 18；Buffer gear includes：Spring 19, sliding sleeve 20, fixed cover 21；Sliding sleeve 20 is to open
