Abstract
The utility model relates to a hydraulic fixing machine which is a novel powerful hydraulic machine for tightening or disassembling large-scale bolts and nuts in engineering. The utility model is characterized in that a quick joint is respectively arranged on the input end and the output end of a high voltage oil tube of a super voltage electric control hydraulic pump, and the quick joints are fixedly connected with a cylinder piston mechanism which is provided with a piston rod in the middle. The end of the piston rod is connected with racks which are engaged with a circular sector toothed-plate, and a spanner hole is arranged on the circular sector toothed-plate and a pair of engaged ratchet wheel and detent are arranged on the peripheral surface of the spanner hole. The utility model has the advantages of high safety, high efficiency, light weight, etc.
Description
The utility model relates to a kind of the be used for bolt on main equipment, the engineering frame, fastening, the provision for disengagement of hydraulic drive that nut is used.
Existing fastening, demounting bolt, nut all use spanner, rely on manpower to finish.Below M24, can use steam-operating or electronic spanner, and moment values is all less for diameter.For the securing member more than the M24, need great moment values, steam-operating or electronicly all can't method solve all needs manpower, and is time-consuming, takes a lot of work.Efficient is extremely low.
The purpose of this utility model is in order to overcome above-mentioned shortcoming, to provide a kind of hydraulic pressure fastening machine, and it is not only laborsaving, save time but also do not damage the dismounting part.
The purpose of this utility model is achieved in that high-pressure oil pipe output, the input at the automatically controlled hydraulic pump of super-pressure is provided with snap joint, snap joint and cylinder's piston mechanism are affixed, there is piston rod at the piston mechanism center, the end of piston rod is connected with the tooth bar with the sector rack engagement, sector rack is provided with driving hole, and there are a pair of intermeshing ratchet, ratchet in the garden outside the wrench hole on week.
By the driving of liquid cane, make piston rod move back and forth, and promote tooth bar and the wrench hole rotation of sector rack folk prescription on mobile drive sector rack, realize purpose fastening or dismounting.In the use, according to the dismounting object, select the sleeve of check mark for use, with the ratchet center of packing into, the upper end of sleeve, work can successfully be carried out in the lower end on bolt, nut.Ratchet, ratchet play the positioning and locking effect.
Owing to adopt such scheme, the nut of dismounting different-diameter promptly, promptly laborsaving, save time, safe and reliable again.
Below in conjunction with accompanying drawing and enforcement the utility model is further specified.
Fig. 1 is the hydraulic cylinder of the fastening machine of the utility model hydraulic pressure and the structural representation of mechanical driving part.
Fig. 2 is the connection diagram of hydraulic part of the present utility model and the fastening machine of hydraulic pressure.
Fig. 3 is the automatically controlled hydraulic scheme of super-pressure.
Fig. 4 is the time device schematic diagram of the automatically controlled hydraulic pressure of super-pressure.
