Description

Engine cylinder head locker clamping device
Technical field
The invention belongs to technical field of tooling clamps, specifically, the device of particularly pneumatic pressure locker.
Background technology
Valve collet is installed in the engine cylinder head, is used for valve spring spacing.At present, the installation of valve collet all relies on the manual press-loading device to carry out: fix a guide pile on work top, cylinder head is placed on the guide pile, the bottom of inlet valve or exhaust valve is propped up by guide pile, then valve collet is placed on the cylinder head, operator dynamic pressure assembling device is pressed into valve collet in the corresponding valve.The deficiency of above press-fit approach is:
1, cylinder head easily produces on guide pile and rocks, and is difficult to contraposition when press-fiting valve collet, need repeatedly press-fit usually and valve collet could be pressed into position accurately, and not only efficiency of assembling is lower, complicated operation, and working strength of workers is very big.
2, to press-fit the position of valve collet be metalwork to the manual press-loading device, causes the damage of valve and locker when press-fiting easily.
3, because the position of guide pile and manual press-loading device can't be regulated, therefore only be applicable to the cylinder head of specific model, versatility is relatively poor.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of contraposition that is easy to, and can effectively improve the engine cylinder head locker clamping device of efficiency of assembling.
Technical scheme of the present invention is as follows: a kind of engine cylinder head locker clamping device, comprise base plate, standpipe, air cylinder fixed plate, cylinder, rubber pressure head and cylinder head fixed head, wherein base plate is a slab construction, vertical fixing standpipe on the plate face of base plate one end, the upper end of this standpipe is equipped with air cylinder fixed plate, described air cylinder fixed plate parallels with base plate, cylinder is installed on air cylinder fixed plate, the piston rod of described cylinder stretches out straight down, the rubber pressure head is installed in the bottom of cylinder piston rod, and cylinder piston rod under be provided with the cylinder head fixed head.
Adopt above technical scheme, cowl hood is gone into the cylinder head fixed head, and cylinder head is to lopsidedness, make inlet valve just in time be positioned at cylinder piston rod under, this moment the inlet valve locker is positioned over the position of cylinder head inlet valve, start the control button of cylinder then, the piston rod of cylinder is stretched out straight down, cylinder piston rod is pressed into the inlet valve locker in the cylinder head inlet valve fast by the rubber pressure head; After treating that the inlet valve locker clamping is good, cylinder head is tilted towards opposite side, make exhaust valve just in time be positioned at cylinder piston rod under, be positioned over the position of cylinder head exhaust valve with the exhaust valve locker this moment, start the cylinder control button, the exhaust valve locker can be pressed in the cylinder head exhaust valve fast.
Because the cylinder head fixed head is positioned at cylinder head when press-fiting, four angles of cylinder head fixed head form in cylinder head effectively and support, can guarantee that cylinder head does not rock, help the cylinder head location like this, and contraposition is easy between cylinder piston rod and the cylinder head valve collet, only needs once valve collet to be pressed in the corresponding valve, has both reduced working strength of workers, simplify operation, improved efficiency of assembling again greatly.Simultaneously, cylinder piston rod adopts the rubber pressure head to contact with valve collet, can prevent effectively that air-stop gate or valve collet damage.
Described air cylinder fixed plate is welded on the excircle of positioning tube, and this positioning tube is inserted in the upper end of standpipe, is equipped with screw mandrel in described positioning tube from top to bottom, both threaded engagement, and the lower end of described screw mandrel is stretched in the standpipe, and the end face of positioning tube is stretched out in the upper end of screw mandrel.Above structure is in rotary screw rod, and screw mandrel drives positioning tube and moves up and down along standpipe, and air cylinder fixed plate and cylinder are synchronized with the movement with positioning tube, can adjust the height and position of cylinder so as required easily.
Upper end at described screw mandrel is provided with round turntable, and the following card and the screw mandrel of this rotating disk are perpendicular, and vertical fixing has a driving lever in the submarginal position of rotating disk upper disk surface.Above structure can realize the rotation of screw mandrel by stirring driving lever, and is convenient and labor-saving.
For simplified structure, be convenient to assembling, and guarantee that the rubber pressure head installs firmly, the longitudinal cross-section of described rubber pressure head is " ⊥ " shape, link to each other with platen by reference column and to form, fit in the bottom surface of described platen and cylinder piston rod, reference column stretches in the piston rod of cylinder, both interference fit.
Below described cylinder head fixed head, be symmetrically arranged with two square journal stirrups, the transverse slat part of these two journal stirrups fits with the bottom surface of cylinder head fixed head, and it is fixing by welding, the riser of two journal stirrups partly is positioned at the both sides of column cap upper end, connect by pin between the three, the lower end of described column cap is welded on the base plate.The installation of cylinder head fixed head is firm on the one hand for above structure, can guarantee the effective support to cylinder head; On the other hand, the cylinder head fixed head is detachable, and the cylinder head fixed head of replaceable different size can be realized the cylinder head of institute's organic type is press-fited so as required.
Beneficial effect: cylinder head did not rock when the present invention can guarantee to press-fit, and the cylinder head location is reliable, and contraposition is easy, only need once valve collet to be pressed in the corresponding valve, not only reduce working strength of workers, simplified operation, and improved efficiency of assembling greatly.The present invention can also prevent effectively that air-stop gate or valve collet damage, and highly versatile, can satisfy the needs that press-fit of all size cylinder head.
