Summary of the invention
Utility model object: the purpose of this utility model is for the deficiencies in the prior art, provides a kind of easy to use, can effectively improve the boring technological equipment of the excavator connecting rod of connecting rod production efficiency.
Technical scheme: the utility model provides a kind of boring technological equipment of excavator connecting rod, comprise base plate and be fixed on the la m on base plate, on described la m, be provided with top plate, on described top plate and described la m, be provided with the centrepin that runs through la m and top plate, described la m and top plate are rotationally connected around centrepin; On described la m and top plate, be respectively equipped with two groups for inserting the fixing hole of alignment pin; Described top plate is provided with compacting part, is provided with multiple locating pieces at the edge of any two intersection edges of described top plate.
Further, because the diameter of excavator connecting rod two ends axle bed and bearing may be different, thereby cause the center of two ends bore hole not in the same horizontal line, in order to guarantee that when the bore hole, the center at two ends is at same level height, so be provided with the groove for placing backing plate on top plate, described groove is arranged on one end of top plate, thickness that like this can more needed height adjustment backing plate, thus use more conveniently, also can be applicable to the excavator connecting rod of different model.
Further, described two groups of fixed hole positions, in the both sides of centrepin, can guarantee that, in the time of bore hole, top plate can firmly be fixed on la m like this, can not rotate around centrepin because of vibration, effectively raise the accuracy of bore hole.
Further, described compacting part comprises the edge on two relative both sides that are fixed on top plate and perpendicular to top plate lead, between described two leads, is provided with pressing plate, and this compacting part is simple in structure, and good fixing effect is convenient to use.
Further, described centrepin is arranged on the center of la m and top plate, in the time of fixing excavator connecting rod, the Center-to-Center pin of excavator connecting rod can be coincided like this, more convenient so when in use.
Further, the outer wall of described centrepin is provided with axle sleeve, in described two groups of fixing holes, is provided with axle sleeve, can effectively reduce like this friction between centrepin and alignment pin and top plate and la m, prevents from causing bore hole error because of the isostructural distortion of fixing hole.
Further, convenient for frock is used, described alignment pin adopts step bearing pin.
Operation principle: the utility model is made into rotatable by the boring technological equipment of excavator connecting rod, when work, excavator connecting rod is fixed on the utility model, then be fixed on boring machine, first use bore hole is carried out in one end of connecting rod, after one end bore hole finishes, fixing after only the top plate of boring technological equipment need to being horizontally rotated to 180 °, just can directly carry out bore hole to the other end of connecting rod.
Beneficial effect: compared with prior art, the utility model not only uses convenient, quick; And in the time adopting the utility model, saved the operation that repeats tool setting, effectively raise the production efficiency of excavator connecting rod; Meanwhile, adopt the utility model can effectively improve the accuracy of bore hole.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is working state figure of the present utility model.
The specific embodiment
Below technical solutions of the utility model are elaborated, but protection domain of the present utility model is not limited to described embodiment.
As depicted in figs. 1 and 2, the boring technological equipment of excavator connecting rod of the present utility model, comprise the base plate 1, la m 2 and the top plate 3 that set gradually from bottom to up, wherein on base plate 1, be provided with the bolt fixing with boring machine mounting plate, facilitate the utility model can be fixed on the supporting plate of boring machine in the time of work; La m 2 is fixed on base plate 1, top plate 3 is arranged on la m 2, be provided with the centrepin 4 through two plates simultaneously at the central point of top plate 3 and la m 2, top plate 3 can rotate around centrepin 4 on la m 2, outer cover at centrepin 4 has axle sleeve, can effectively reduce like this friction between centrepin 4 and top plate 3 and la m 2; On the top plate 3 of centrepin 4 both sides and la m 2, dig two groups of fixing holes 6, in the time that the utility model is worked, alignment pin 5 has been inserted in fixing hole 6 and just top plate 3 can be fixed on la m 2; On top plate 3, be provided with for excavator connecting rod being fixed on to the compacting part 7 on plate 3 last time, wherein compacting part 7 comprises two leads 10 perpendicular to top plate 3, between two leads 10, be provided with pressing plate 11, the two ends of pressing plate 11 are fixed on two leads 10 by screw bolt and nut, and the height of pressing plate 11 can regulate according to the thickness of excavator connecting rod; Be provided with locating piece 8 at the edge of two adjacent edges of top plate 3, can effectively prevent that like this excavator connecting rod from sliding at work, thereby cause the problems such as bore hole position is inaccurate.One end of top plate 3 upper surfaces is provided with the groove 9 for placing backing plate, the backing plate that can prevent differing heights in groove 9 guarantee the two ends of excavator connecting rod bore hole center in the same horizontal line.
