Abstract
The invention provides a clamp for boring of a bearing cap of a camshaft of an engine cylinder head. The clamp for boring of the bearing cap of the camshaft of the engine cylinder head comprises a locating and supporting base where the bearing cap is placed. The locating and supporting base is fixedly connected with a machine tool through two bolts. Two cylinder locating pins and two rhombus locating pins are installed on the locating and supporting base. A semicircular hole is formed between the cylinder locating pins and the rhombus locating pins. By the adoption of the clamp, two bearing caps can be clamped at the same time, machined workpieces are convenient to replace, and the machining efficiency is high.
Description
Technical field
The present invention relates to field of machining, be specifically related to engine cylinder cover camshaft-bearing cap boring jig.
Technical background
At present the fixed form of domestic automobile engine cam on its cylinder cap be generally by a whole frame installation above engine cylinder cover, and fixedly complete by some bolts.On whole framework, be cast with the half camshaft bearing hole corresponding with cylinder cap, after this dead eye bearing cover bolt corresponding with it is fixing, need to carry out accurate processing to it and meet the performance requirement of engine operation to guarantee whole camshaft hole, be generally that bearing cap will carry out one time Boring before fine finishining, just can carry out this finishing step afterwards; But in most Boring process, often adopting built-up jig general on lathe to realize frock clamps, this just needs operator to possess very masterful technique, and operator is consuming time a lot of when selecting and general built-up jig is installed, and this has caused again impact to cylinder cap bearing cap working (machining) efficiency; Secondly, bearing cap of each clamping of Boring of ordinary circumstance lower ball cover, working (machining) efficiency is lower.
Summary of the invention
In order to address the above problem, the invention provides a kind of can two bearing caps of clamped one time, processing work is changed convenient, the engine cylinder cover camshaft-bearing cap boring jig that working (machining) efficiency is high.
Engine cylinder cover camshaft-bearing cap boring jig of the present invention, comprise for placing the positioning supports seat of bearing cap, described positioning supports seat is fixedly linked by two bolts and lathe, two cylindrical positioning pins and two diamond positioning pins are installed on positioning supports seat, between described cylindrical positioning pins and diamond positioning pin, offer a semicircle orifice.
Preferably, the semicircle orifice between cylindrical positioning pins and diamond positioning pin is consistent with the specification requirement of engine cylinder head camshaft hole.
Preferably, cylindrical positioning pins is corresponding with the pin-and-hole being placed on positioning support bearing upper ball cover with the position of diamond positioning pin in positioning support bearing.
More preferably, cylindrical positioning pins and diamond positioning pin lay respectively at round hole axial both sides, and symmetrically.
The present invention once can two bearing caps of clamping, and processing work is changed convenient, and working (machining) efficiency is high.
Accompanying drawing explanation
Fig. 1 is engine cylinder cover camshaft-bearing cap boring clamp structure schematic diagram.
Reference numeral: 1-cylindrical positioning pins, 2-positioning support bearing, 3-diamond positioning pin, 4-bearing cap, 5-bolt.
The specific embodiment
Engine cylinder cover camshaft-bearing cap boring jig of the present invention, comprise for placing the positioning supports seat 2 of bearing cap 4, described positioning supports seat 2 is fixedly linked by two bolts 5 and lathe, two cylindrical positioning pins 1 and two diamond positioning pins 3 are installed on positioning supports seat 2, between described cylindrical positioning pins 1 and diamond positioning pin 3, offer a semicircle orifice, semicircle orifice is consistent with the specification requirement of engine cylinder head camshaft hole, cylindrical positioning pins 1 is corresponding with the pin-and-hole that is placed on positioning support bearing 2 upper ball covers 4 with the position of diamond positioning pin 3 in positioning support bearing 2, cylindrical positioning pins 1 and diamond positioning pin 3 lay respectively at round hole axial both sides, and symmetrically.
During use, in positioning support bearing 2, specific two screwed holes of location arrangements, are fixed on positioning support bearing 2 on lathe by screwed hole with two bolts 5.Two cylindrical positioning pins 1 and two diamond positioning pins 3 are installed on positioning support bearing 2, then between cylindrical positioning pins 1 and diamond positioning pin 3, are offered a semicircle orifice consistent with the specification requirement of engine cylinder head camshaft hole.Then the bearing cap 4 for the treatment of bore hole is placed in positioning support bearing to 2 by cylindrical positioning pins 1 and diamond positioning pin 3, finally with the clamping element on lathe push down bearing cap above.Like this, as long as start lathe, just can carry out bore hole to this bearing cap.
