Description
Technical field
The utility model relates to the detent mechanism field, the four paws detent mechanism on especially a kind of double-cylinder horizontal hydraulic press that is applied in crawler belt assembling.
Background technology
During the assembling crawler belt, by the final Stroke Control pin overhang and the guide overhang of forcing press two oil cylinders, whether the position dimension that decision press-fits the left and right sides, back chain link bolt hole reaches drawing requirement.The chain link size that has has deviation will cause bolt hole position degree and creeper tread position degree not to match, and the operator needs frequent adjustment oil cylinder stroke satisfy bolt hole position degree drawing dimensional requirement, causes that pitch time is long, machining accuracy is low.
Summary of the invention
The purpose of the utility model just is to overcome the deficiency that exists in the above-mentioned prior art, and the four paws detent mechanism of a kind of simple in structure, compact to design, dependable performance, accurate positioning is provided.
The technical scheme of the utility model is:
A kind of four paws detent mechanism; Comprise an installing rack, it is characterized in that: also comprise magnet ring sensor, guide rail, guide pad, cylinder and four locating detents, guide rail is installed in the dual-side of installing rack bottom respectively; Two guide pads of suit all slide on the guide rail of every side; The inboard of two guide pads connects through cylinder, and the outside connects through the magnet ring sensor, at the bottom surface of each guide pad a locating detent is installed vertically all.
And described magnet ring sensor and cylinder all are two, and guide pad is four, and guide rail is four of setting parallel to each other, and there are two groups of guide rails up and down the installing rack below, and each guide pad all slides on two of side guide rails parallel to each other.
And, the installed inside cylinder of one of them guide pad of said every side, the inboard of another guide pad is connected with the cylinder bar of cylinder.
And the magnet ring sensor is installed in the outside of one of them guide pad of said every side, and this magnet ring sensor is connected with another guide pad through installing rack.
And the lower surface of described locating detent is hemisphere face or cambered surface.
And, equal suit one spring on the body of rod of described each locating detent.
The utlity model has following advantage and good effect:
1, this four paws detent mechanism is simple in structure, volume is little, in light weight, compact to design, dependable performance, long service life and cost are low.
2, this four paws detent mechanism pitch time is short, has significantly improved production efficiency.
3, hemisphere face or cambered surface are all processed in the lower end of each locating detent in this four paws detent mechanism, even the four paws holding fix has deviation, four paws also can the deadweight effect under automatic capturing, be inserted in the bolt hole, avoided potential safety hazard.
4, guide pad slides on two parallel to each other and heat treated metal guide rails, and the hole that guide pad cooperates with guide rail embeds linear bearing, can guarantee the slip that guide pad is unobstructed like this, can reduce the deflection of guide rail again greatly, makes it accurate positioning.
5, in this four paws detent mechanism the four paws body of rod to attend the spring of institute's suit very big, when four paws fell, spring played very big cushioning effect, so did not almost have the effect of power between four paws and the chain rail joint.
6, the form of cascaded surface is adopted in the guide pad lower end, and so mating surface is in the lower end of guide pad, and joint face is in the side of guide pad.Even a little distortion appears in four paws, power also can scatter, and the material of guide pad is very hard, is unlikely to damage.
7, the utility model is that a kind of design science, rational in infrastructure, easy to use, frame for movement are stable; Four paws detent mechanism on the double-cylinder horizontal hydraulic press that is applied in the crawler belt assembling of high, the practical and long service life of positioning accuracy, this detent mechanism have can simplify work flow, reduce operation easier, improve positioning accuracy, shorten positioning time and improve advantages such as working (machining) efficiency.
Description of drawings

Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
A kind of four paws detent mechanism; Comprise an installing rack 6, also comprise two magnet ring sensors 1, four guide rails 2, four guide pads 3, two cylinders 5 and four locating detents 4, guide rail is installed in the dual-side of installing rack bottom respectively; Guide rail is four of setting parallel to each other; And be divided into two groups up and down, and two guide pads of suit that all slide on the guide rail of every side, promptly each guide pad all slides on two of side guide rails parallel to each other.
The inboard of two guide pads connects through cylinder, i.e. the installed inside cylinder of one of them guide pad of every side, and the inboard of another guide pad is connected with the cylinder bar of cylinder.
The outside of two guide pads connects through the magnet ring sensor, and promptly the magnet ring sensor is installed in the outside of one of them guide pad of every side, and this magnet ring sensor is connected with another guide pad through installing rack.
At the bottom surface of each guide pad a vertical locating detent is installed all, the equal very strong buffer spring of suit one elasticity on the body of rod of each locating detent, and the lower surface of each locating detent is hemisphere face or cambered surface.
The course of work of the utility model is:
When oil cylinder advances to holding fix, give the four paws signal, four paws falls, if four paws and original holding fix have deviation, because the lower end of four paws is hemisphere face or cambered surface, so the effect of a fine setting is arranged.Four paws can continue to fall under the deadweight effect, up to the centering position and insert in the bolt hole of chain rail joint.Oil cylinder drives four paws and moves on, and the magnet ring sensor on four paws is given signal, and four paws mechanism rises, and oil cylinder stops and returning, and wholely press-fits action and accomplishes.At this moment, guide rail moves to initial position in the effect lower edge of cylinder for guide pad and four locating detents.
Four paws and guide pad receive the effect of a moment when press-fiting, and guide rail also has diastrophic trend at this moment.Take place for fear of this situation, guide pad and four paws adopt special connected mode, that is: the harder metal of material is used in guide pad thickening; Guide rail use two diameters thick, through Overheating Treatment, accurately machined antifriction metal (AFM) rod, just can significantly reduce flexural deformation, the accurate location of assurance four paws.
