Abstract
The invention discloses a pressure head assembly for assembling of engine valve lock plates. The pressure head assembly comprises a cover plate, a pressure head, a sleeve, a spring, a guide rod, a clamp plate, a steel ball and a snap ring, wherein the cover plate is detachably connected with the pressure head; the spring and the guide rod are arranged in the pressure head; one end of the spring presses the upper end of the guide rod and the other end of the spring abuts on the cover plate to ensure that the guide rod can move up and down; the clamp plate is mounted outside the pressure head and used for clamping a lock plate into a valve slot; the sleeve is connected with the pressure head by a screw; a circular groove is engraved in the lower part of the sleeve; two taper holes are formed in the circular groove; a steel ball is arranged in each taper hole; a snap spring is also arranged in the circular groove; the snap spring and the steel balls are used for fixing a spring upper seat on the pressure head. The pressure head assembly for assembling of engine valve lock plates is simple to manufacture and reliable in action; the production takt is less than or equal to 30 sec; the percent of pass is greater than or equal to 99%; refit can be directly carried out on the original equipment. According to the pressure head assembly for assembling of engine valve lock plates, the industrial difficulty of press fitting of trislot lock plates is effectively solved and the automatic assembling can be conveniently realized.
Description
Technical field
The present invention relates to technical field of tooling clamps, be specifically related to the pressure head component of a kind of automotive engine valves three groove locking plate assembling.
Background technology
In automobile industry, in engine assembly process, three groove locking plate press-loadings are a difficult problem for whole industry at present.At present, the valve split collets assembling mode that each manufacturer adopts is: as Fig. 1: be loaded on by locking plate in the spring seat of honour, be stuck on pressure head or be positioned in valve spring, being press-fited by press.The defect of this kind of press-fit approach is: valve spring freely swinging on cylinder cap is larger, when causing press-fiting, the axial line of valve stem and the spring seat of honour and pressure head is located inaccurate, easily cause locking plate press-loading failure, cause press-fiting and cannot complete smoothly, the efficiency press-fited is lower, not only increase the workload of workman, and require higher to the proficiency of workman.Existing three groove locking plate press-loadings generally adopt gravity to make locking plate enter groove or utilize air-flow to blow several assembling modes that locking plate enters groove.Its shortcoming is productive temp longer (about 60 seconds); Qualification rate low (about 90%).And existing press-loading device is all manual equipment substantially; External same category of device is very complicated; Expensive; Only single pressuring head part needs about 40,000 yuan.
Summary of the invention
Goal of the invention: for the defect of prior art, the present invention is proposed the pressure head component of a kind of engine valve three groove locking plate assembling.
Technical scheme: a kind of pressure head component of engine air valve locking plate assembling, described pressure head component comprises: cover plate, pressure head, sleeve, spring, guide rod, clamping plate, steel ball, jump ring, described cover plate and pressure head removably connect, and are provided with spring and guide rod in pressure head, and spring one end is pressed in guide rod upper end; The other end supports on the cover board, and guide rod is moved up and down;
Pressure head outside is provided with clamping plate, and for sandwiching in spiracular furrow by locking plate, sleeve and pressure head adopt screw to be connected, and lower cartridge is carved with cannelure, has 2 bellmouths in cannelure; 1 steel ball is respectively housed in bellmouth; The jump ring blocking steel ball is housed outside cannelure, and the spring seat of honour is fixed on sleeve by jump ring and steel ball.
As preferably, described cover plate and pressure head adopt screw to be connected, and pressure head outside is provided with clamping plate, for being sandwiched in spiracular furrow by locking plate.
Beneficial effect: the present invention makes simply; Reliable in action; Productive temp is high≤and 30 seconds.Qualification rate is high >=and 99%.Generally directly to reequip on existing equipment.Efficiently solve an industry difficult problem for three groove locking plate press-loadings, Automated assembly can be realized very easily.

Detailed description of the invention
A pressure head component for engine air valve locking plate assembling, described pressure head component comprises: cover plate 1, pressure head 2, sleeve 3, spring 4, guide rod 5, clamping plate 6, steel ball 7, jump ring 8, cover plate 1 and pressure head 2 removably connect, and be provided with spring 4 and guide rod 5 in pressure head 2, spring 4 one end is pressed in guide rod 5 upper end; The other end is against on cover plate 1, and guide rod 5 can be moved up and down;
Pressure head 2 outside is provided with clamping plate 6, for locking plate 10 is sandwiched in spiracular furrow 9, sleeve 3 adopts screw to be connected with pressure head 2, cannelure is carved with in sleeve 3 bottom, 2 bellmouths are had in cannelure, 1 steel ball 7 is respectively housed in bellmouth, and cannelure is also equipped with jump ring 8, and the spring seat of honour 41 is fixed on pressure head 2 by jump ring 8 and steel ball 7.In the present invention, cover plate 1 adopts screw to be connected with pressure head 2.
During use, valve is fixed on workpiece, and pressure head component is put into by material loading frock in locking plate and the spring seat of honour; Locking plate is pressed on guide rod 5 by clamping plate 6.When pressure head component is with locking plate and spring seat of honour press-in valve; Guide rod 5 is withstood when being moved upwards up to locking plate position in valve upper end; Locking plate is sandwiched valve locked groove by clamping plate 6; Now pressure head component moves up disengaging workpiece; Valve drives locking plate to move down and enters in the taper hole of the spring seat of honour.Complete locking plate press-loading.
Below, the advantage of the present invention and prior art is embodied with form.
