Abstract
The utility model provides a bearing-cover boring clamp. According to the technical scheme, a positioning plate is fixed on a base plate and provided with two positioning pins; the positioning plate and the two positioning pins form the mode of positioning of one plate and two pins; two side surfaces of the positioning plate are provided with movable pressing plates respectively; the outer sides of the movable pressing plate are provided with hydraulic oil cylinders; and the piston rods of the hydraulic oil cylinders are connected with the movable pressing plates. When the bearing-cover boring clamp is in use, the semi-circular hole of a bearing cover is positioned upwards by the positioning plate, and the two movable pressing plates are driven by the hydraulic oil cylinders to move oppositely, thus the bearing cover is pressed and bored. The bearing-cover boring clamp can press hydraulically, positions the bearing cover reliably and finishes boring in one time, thereby guaranteeing the processing quality and improving the processing efficiency by 10-15%.
Description
Technical field
The utility model relates to semicircle orifice processing, especially the bearing cap boring jig of bearing cap.
Background technology
The development of the dCi11 engine assembly of commercial car company is the core force of high-power vehicle, large-scale cargo vehicle grows with each passing day to the demand of dCi11 engine, the engine bearing lid is its key components and parts, and output can constantly increase along with assembly, and there is very large prospect market demand aspect.FE Tiler output reaches 30,000 per month, improves working (machining) efficiency, just seems very important.
At present, for the semicircle orifice processing of bearing cap, two are closed circle, manually fastening, because centre deviation is arranged, minute 2 Borings cause the loss of working (machining) efficiency because of the technique of installation way and processing.
Summary of the invention
In order to guarantee the semicircle orifice crudy of bearing cap, improve working (machining) efficiency, the utility model proposes the bearing cap boring jig.
The technical solution adopted in the utility model is as follows: the bearing cap boring jig, comprise base plate, and it is characterized in that: be fixed with location-plate on the base plate, location-plate is provided with two alignment pins, and location-plate and two alignment pins consist of the plane and two pits location; Two sides at location-plate are respectively equipped with movable pressing board, are provided with hydraulic jack in the outside of movable pressing board, and the piston rod of hydraulic jack is connected with movable pressing board.
Beneficial effect: during use, the semicircle orifice of bearing cap upwards in the location-plate location, drives two movable pressing board move toward one another by hydraulic jack, thereby compresses bearing cap, realizes bore hole.The utility model adopts hydraulic compression, and the bearing cap location is reliable, once finishes bore hole, has guaranteed crudy, and working (machining) efficiency has improved 10-15%.
