Specific embodiment
Referring to accompanying drawing, a kind of rack-and-pinion cylinder self-locking hydraulic press for being provided with position sensor, including：Housing 11, gear teeth
Bar cylinder, toggle, limitation locking device and position sensor 10；
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
Seal 16, be located at the venting plug 22 at 15 two ends of cylinder body；After 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 spacing, preformed hole insert stop pin 14
Right side is carried out to bent axle 12 spacing, make bent axle 12 realize locking in top dead-centre, it is to avoid shake because of jolting or maloperation makes tooth
Wheel rack cylinder self-locking hydraulic press unblock；
Position sensor 10 is located on housing 11, and when bent axle 12 goes to top dead-centre or bottom dead centre, position sensor 10 is just
To one in default 2 grooves on bent axle 12, the signal in place of bent axle 12 is fed back；
When bent axle 12 goes to bottom dead centre, bent axle 12 is locked by the stroke of piston 18 in rack-and-pinion cylinder, i.e., when work as
When piston 18 moves to range, bent axle 12 just arrives the position of bottom dead centre.
Further, said gear rack cylinder self-locking hydraulic press also includes：The buffer gear being located on the outside of piston 18；Buffering
Mechanism includes：Spring 19, sliding sleeve 20, fixed cover 21；Sliding sleeve 20 is hatch frame, and which passes through spring 19 and contradicts company with piston 18
Connect, fixed cover 21 is arranged on 15 end side of cylinder body.When piston 18 runs to is close to range, sliding sleeve 20 encounters cylinder body 15
End, compression spring 19, the opening on sliding sleeve 20 indentation fixed cover 21, the hydraulic oil in spring chamber after a segment distance is compressed
Can only flow out from the fine gap of sliding sleeve 20 and fixed cover 21, thus play buffering that piston 18 and tooth bar 17 are moved and subtract
Noise contributions, and optimize force-bearing situation when 1 bringing onto load of pull bar runs.
Further, said gear rack cylinder self-locking hydraulic press may also include：The scraping dirt being located at 11 upper end open of housing
Ring 2；Dirt-scrapping ring 2 is used for removing the dirt on pull bar 1.
