Description
Technical field:
The utility model relates generally to a kind of mechanical device, relates in particular to a kind of hydraulic pressure device of helping pull a cart
Background technology:
Help pull a cart is with forcing press the steel bushing of column type to be compressed into part, help pull a cart method and corresponding apparatus of the part of the existing instrument and meter for automation valve that uses has following defective: the stainless steel steel bushing is pressed into not to be had guiding and is difficult to select to locate benchmark in the hole in, usually need the staff with hand steered positive guide pin bushing in the course of the work, with the naked eye stravismus is observed as the method for aiming at hole on the bonnet,, cause the dangerous situation that guide pin bushing and bonnet, hole decentraction and finger are pressed that is pressed into, so, be easy to generate industrial injury, staff's personal safety is on the hazard, and inefficiency, technology is demanded urgently improving.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, and a kind of hydraulic pressure device of helping pull a cart is provided.It has optimized the technology making, overcomes with the customary practice of hand steered positive steel bushing as the location, avoids industrial injury, has improved production efficiency, has realized carrying out production strictly in line with rules and regulations of hommization.
The utility model is achieved through the following technical solutions:
The hydraulic pressure device of helping pull a cart includes frame, and it is characterized in that: frame includes upper and lower gripper shoe and pillar, and pillar is fixed between the upper and lower gripper shoe, and perforate is arranged on the upper backup pad, is set with the supporting disk of tubular in the perforate; Oil cylinder is installed on the lower supporting plate, and the piston rod top of oil cylinder is fixed with pull bar; There is annular groove described supporting disk upper surface, there is axis hole in the central authorities of annular groove, are placed with the short cover in location in the described axis hole, and there is perforation in the short cover in described location central authorities, location short cover outer wall has the ring-shaped step retaining in described axis hole upper edge, and described pull bar passes the perforation in the middle of the short cover in location; Pull bar upper end is set with the tubular guide, and tubular guide overcoat has guide pin bushing, and there is annular protrusion the cylindrical pin set upper side, and guide pin bushing is positioned at the annular protrusion below, and what the pull bar top was equipped with spacing usefulness adds tight coupling fast.
The syndeton of described piston rod and pull bar is: the piston rod top is sleeved in the adapter sleeve of tubular of end closure, there is perforate the upper surface of adapter sleeve, the perforate that the pull bar lower end is passed on the adapter sleeve is stretched in the adapter sleeve, and there is the annular boss that prevents that pull bar from shifting out from perforate the pull bar bottom; Be connected by the internal and external threads that cooperatively interacts between described piston rod top and adapter sleeve.
Described to add tight coupling fast be nut, and nut is spun on the pull bar top.
Supporting disk is actually an instrument that part to be processed is put, and the external screw thread of its interior boring ratio part is more bigger, satisfies part and puts into taking-up and all make things convenient for and get final product.The location weak point that is equipped with on the practical significance in the central authorities of supporting disk overlaps, and has realized so fast part being placed on the correct position.
When processed part is placed in the supporting disk, to lack cover and also insert on the centre bore of part, strictness has limited moving of part.After part is installed, hydraulic system provides power that piston rod is pulled down, piston rod drives pull bar and also moves downward, along with pull bar constantly moves down, be enclosed within on the pull bar the tubular guide by the effect of its annular boss guide pin bushing is pushed in the endoporus of part, guide pin bushing is pressed in the endoporus of part the most at last.
The magnitude range of part is wide, and its central through hole of bigger part is also bigger, and after finishing the operation of helping pull a cart, pull bar can directly therefrom screw out, and its central through hole of less part is also smaller.The stressed screw thread of pull bar lower end is also less relatively, directly has influence on the service life of pull bar.For this reason above it one of design removably to add tight coupling fast be described nut, like this can under the situation that does not screw out pull bar, remove snap joint, drive oil cylinder again pull bar withdrawed from from part, can take out the part of having processed subsequently.Realize changing fast product parts, save non-cutting time, improve productivity effect.
Hydraulic-driven oil circuit in the utility model adopts at a slow speed and oil circuit parallel connection fast, and oil circuit is made up of three position four-way electromagnetic valve, choke valve, the check valve of M type function at a slow speed.The turn choke valve can be realized the microinching of piston rod, and speed is regulated the mode that adopts the in-line throttling.The three position four-way electromagnetic valve internal feature side in parallel with M function valve adopts O type function, and the effect of this valve is the time that reduces idle stroke, satisfies F.F. need of work fast.The commutation signal of magnetic valve work is a flowing mode.
The utility model has the advantages that:
The utility model is relatively simple for structure, and the location is accurate, easily guarantees the coaxial precision of guide pin bushing external diameter and bonnet, endoporus, and high efficiency, has effectively avoided the generation of industrial injury.
