Description
Technical field
The utility model belongs to the Machining of Connecting Rod technical field, relates in particular to a kind of connecting-rod bolts hole processing clamp.
Background technology
In conventional linkage bolt hole process, bolt hole on end cap and gonnecting rod body is integrated processing, by after end cap and gonnecting rod body cooperation, by the fixture one, clamped, processed again the bolt hole of end cap and gonnecting rod body by identical cutter, and, in the actual use procedure of connecting rod, bolt and gonnecting rod body are interference fit simultaneously, and with coordinating of end cap be matched in clearance, therefore the end cap and the bolt hole on gonnecting rod body that process can't meet the use needs simultaneously.
The utility model content
Technical problem to be solved in the utility model is to improve a kind of connecting-rod bolts hole processing clamp of being convenient to bolts assemblies on connecting rod.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of connecting-rod bolts hole processing clamp, comprise base plate, described base plate is provided with clamping device, described clamping device comprises and being arranged on base plate and perpendicular riser, described riser both sides are respectively equipped with the first pressing plate and the second pressing plate, the outside of described the second pressing plate is provided with pressure strip, screw rod is successively through the first pressing plate, riser, the second pressing plate and pressure strip, and can in riser and the second pressing plate, slide, and be fixedly connected with pressure strip; Described riser two sides is equipped with bearing for the positioning linkage rod end cap, with the suitable alignment pin of connecting rod small end hole, for the block of positioning linkage rod body; Also comprise housing screw, described housing screw is threaded with pressure strip, and the end of housing screw contacts with pressure strip.
Described screw rod has two, lays respectively at pressure strip near the end positions place, and described housing screw is between two screw rods.
The aperture of the screw rod installing hole on the second pressing plate is greater than the external diameter of described screw rod, and described the first pressing plate is connected with screw flight, and on described screw rod, corresponding riser position is set with sleeve, and described sleeve can slide in riser.
Described base plate is provided with two groups of clamping devices, lays respectively at base plate near the end positions place.
The utility model has the advantage of, change original gonnecting rod body and the processing of the bolt hole one on end cap into processing respectively, and use different cutters, make the bolt hole on gonnecting rod body and end cap become different apertures, to adapt to the assembling of bolt; This fixture clamping efficiency is high simultaneously, and the base plate both sides are equipped with a clamping device, are evenly distributed, and balance is good; The riser both sides all can clamp one group of gonnecting rod body and end cap, and a sleeve clamp can clamp four groups of gonnecting rod bodies and end cap altogether, and working (machining) efficiency is high; The corresponding riser of screw rod position is set with sleeve, can effectively protect the external screw thread of screw rod.
The accompanying drawing explanation
The structural representation that Fig. 1 is a kind of connecting-rod bolts hole processing clamp of the utility model;
The structural representation that Fig. 2 is Fig. 1 connecting-rod bolts hole processing clamp;
Mark in above-mentioned figure is: 1, base plate, 2, riser, the 3, first pressing plate, the 4, second pressing plate, 5, screw rod, 6, pressure strip, 7, housing screw, 8, sleeve, 9, bearing, 10, block, 11, alignment pin.
The specific embodiment
The structural representation that Fig. 1 and Fig. 2 are a kind of connecting-rod bolts hole processing clamp of the utility model, comprise base plate 1, base plate 1 is provided with clamping device, clamping device comprises and being arranged on base plate 1 and perpendicular riser 2, the outside that riser 2 both sides are respectively equipped with the first pressing plate 3 and the second pressing plate 4, the second pressing plates 4 is provided with pressure strip 6, and screw rod 5 is successively through the first pressing plate 3, riser 2, the second pressing plate 4 and pressure strip 6, and can be in riser 2 and the interior slip of the second pressing plate 4, and be fixedly connected with pressure strip 6; Riser 2 two sides are equipped with bearing 9 for the positioning linkage rod end cap, with the suitable alignment pin 11 of connecting rod small end hole, for the block 10 of positioning linkage rod body; Also comprise housing screw 7, housing screw 7 is threaded with pressure strip 6, and the end of housing screw 7 contacts with pressure strip 6.
The method of connecting-rod bolts hole processing clamp processing connecting rod bolt holes comprises the following steps:
1), connecting rod is placed on the detent mechanism on riser 2 two sides, end cap is by bearing 9 location, gonnecting rod body is by alignment pin 11 and block 10 location;
2), tighten housing screw 7, make the first pressing plate 3 and the second pressing plate 4 compress gonnecting rod body and end caps;
3), open Digit Control Machine Tool, by the Numerical Control Programming content, with cutter, the gonnecting rod body upper bolt hole is processed;
4), after the gonnecting rod body upper screwed hole machines, Digit Control Machine Tool tool changing, then opposite end covers bolt hole and processed.
After adopting such structure, change original gonnecting rod body and the processing of the bolt hole one on end cap into processing respectively, and use different cutters, make the bolt hole on gonnecting rod body and end cap become different apertures, to adapt to the assembling of bolt; This fixture clamping efficiency is high simultaneously, and base plate 1 both sides are equipped with a clamping device, are evenly distributed, and balance is good; Riser 2 both sides all can clamp one group of gonnecting rod body and end cap, and a sleeve clamp can clamp four groups of gonnecting rod bodies and end cap altogether, and working (machining) efficiency is high; The corresponding riser of screw rod 52 positions are set with sleeve 8, can effectively protect the external screw thread of screw rod 5.
