Description
Technical field
The present invention relates to auto parts and components, be specifically related to a kind of valve lock dog assembling device.
Background technology
In automobile engine, generally need the installation and removal being carried out valve lock dog by special device.During the assembling of valve lock dog, need the tension force overcoming valve spring, valve spring is compressed certain altitude and keeps compressive state not change, use specific purpose tool to be assembled to by valve lock dog in the corresponding annular groove of valve stem in turn simultaneously, be loaded on valve seating, then unclamp valve spring, valve lock dog, valve seating, valve shaft fit tightly together by valve spring under the effect of himself tension force.The difficult point of valve lock dog assembling is, valve spring must be compressed certain altitude and remain unchanged, this just needs to overcome the powerful tension force of valve spring, and the tension force of valve spring is usually at more than 200N.
Publication No. is that the Chinese patent of CN102179792A discloses a kind of engine valve lock dog installation and removal frock, this frock utilizes lever principle to reduce pressure assembling force, and use index dial to regulate and press-fit angle, but operating personnel will always to strut and tie pressure in lock dog installation and removal process, to overcome the tension force of valve spring by manpower, it is large that operating personnel operate labour intensity, causes valve lock dog assembly yield lower.
Summary of the invention
The object of the invention is to propose a kind of valve lock dog assembling device, to reduce the assembling intensity of valve lock dog, and improve the efficiency of assembling of valve lock dog.
A kind of valve lock dog assembling device of the present invention, comprises base, the front side of described base is provided with valve support seat, described valve support seat is provided with downward-sloping and/or from rear to front downward-sloping support platform from front to back, the left side of described base and right side are respectively provided with a support column, the top of described base is provided with a slide bar, the two ends of described slide bar are separately fixed on two described support columns, described slide bar is provided with adjusting slider, the rear portion of described adjusting slider is provided with the through hole with described slide bar matched in clearance, the front portion of described adjusting slider is provided with central axis upright in the screwed hole of the central axis of described through hole, the screw rod through described screwed hole is equipped with in described screwed hole, the upper end of described screw rod is provided with handle, the lower end of described screw rod is fixedly connected with and press-fits sleeve, the described lower surface press-fiting sleeve is provided with the groove for coordinating with valve spring, the bottom of described groove is provided with the resigning hole upwards extended, the described sidewall press-fiting sleeve is provided with the peep hole be communicated with described resigning hole.
Further, described peep hole has two, and is oppositely arranged centered by the described central axis press-fiting sleeve.
Further, the mode that described handle is threaded connection is arranged on the upper end of described screw rod.
Further, described in press-fit sleeve upper end be provided with the installing hole coordinated with described screw rod, described in press-fit between sleeve and described screw rod and fixed by screw.
Further, sleeve and described screw coaxial is press-fited described in.
Further, described valve support seat is provided with four described support platforms; Wherein two support platforms are positioned at described valve support seat rear portion, and downward-sloping all from front to back; Two other support platform is positioned at described valve support seat rear portion, and all from rear to front downward-sloping.
Adopt technique scheme, valve lock dog assembling device has latching characteristics.When press-fiting sleeve compression valve spring, the reverse elastic force of valve spring can be subject to, impel adjusting slider to have and carry out around slide bar the turning moment that rotates, because between the through hole on adjusting slider and slide bar, gap is less, under the effect of the reverse elastic force of valve spring, the contact position of through hole and slide bar can produce moment of friction, moment of friction balances the turning moment of adjusting slider, which achieves valve spring and is compressed rear and automatically keep the latching characteristics of current compression state without adjusting slider meeting under other External Force Actings.Also have automatic adjusting angle function, adjusting slider and slide bar are matched in clearance, and adjusting slider can rotate around slide bar, and to adapt to the requirement of different air valve Spring install angle, maximum adjustment angular range is between 0 ° to 90 ° in theory.
Beneficial effect of the present invention: simple to operate, labour intensity significantly reduces, pass through screw rod, use less turning moment easily to advance to press-fit sleeve and move up and down, and then compression valve spring, add the latching characteristics of adjusting slider, real-time ensuring valve spring can be in constant compression state, greatly reduce labour intensity, improve the success rate of valve lock dog assembling; Efficiency of assembling is high, after completing the valve lock dog assembling of a valve, can will press-fit sleeve and move to another valve place fast, and greatly improve efficiency of assembling along slide bar.
