Abstract
The utility model relates to an assembly device for a one-way valve for a hydraulic tappet. The assembly device for the one-way valve of the hydraulic tappet is characterized in that a locating base is arranged, the upper section of the locating base is a coarse portion, the lower section of the locating base is a thin portion, the thin portion is a cylinder, and a concave hole is formed in the upper end of the thin portion, the thin portion is sleeved with a locating sleeve in a round tube shape, and an annular gap is formed between the inner round wall of the locating sleeve and the outer round wall of the upper end of the thin portion. The assembly device for the one-way valve of the hydraulic tappet has the advantages that the assembly mode of the one-way valve is an obverse assembly mode instead of a reverse assembly mode, a spring base is prevented from turning over by 180 degrees when assembled, a spring of the one-way valve is prevented from being neglected to be installed and being arranged transversely, and the stability of the product quality is further improved. Meanwhile, due to the utilization of an air cylinder and a proximity switch, automation of press fitting is achieved, and production efficiency is improved greatly.
Description
Technical field
The utility model relates to a kind of fitting device.
Background technology
Hydraulic tappet is the parts of automobile engine the inside, and there is a check valve hydraulic tappet inside, and it is comprised of plunger, steel ball, one-way valve spring and spring base.Plunger and spring base interference fit joint, guarantee that steel ball is under hydraulic pressure and spring-force driven dual, opening and closing that can moment.Existing assembling mode is mainly manual flip-over type, and detailed process is as follows: 1. the spring base openend upwards is placed in the working position apparatus locating hole, and each spring base is put an one-way valve spring; 2. put a steel ball on the plunger seal conical surface; 3. hand takes spring base to turn over turnback, then tips upside down on plunger shallow bore hole end; 4. with the Manpower dress, spring base and plunger interference fit are connected.
Why adopting such upside-down mounting mode, is that load is good because the face area of plunger is large, so place as base, obviously, spring base can not meet such requirement.
There is following shortcoming in this assembling mode: 1. one-way valve spring sticks to the spring base endoporus by oil viscosity, at hand, take in 180 degree switching processes, easily cause one-way valve spring to come off and topple over 90 degree, thereby cause the one-way valve spring neglected loading and laterally place, make the hydraulic tappet inefficacy; 2. owing to adopting by hand, press-fit, production efficiency is low.
Summary of the invention
The purpose of this utility model is to provide a kind of hydraulic tappet check valve assembling device to make up the deficiencies in the prior art.
The technical solution adopted in the utility model is: hydraulic tappet check valve assembling device is characterized in that: be provided with positioning seat, the positioning seat epimere is thick section, and hypomere is thin section, and thin section is cylinder, and there is shrinkage pool thin section upper end; Thin section overcoat has the positioning sleeve of circular tube shaped, between positioning sleeve inner round wall and thin section upper end cylindrical wall, annular spaces is arranged.
Optimize, positioning seat and positioning sleeve are installed on slide block, and pressure head is arranged on slide block, and pressure head is done knee-action by air cylinder driven, and cylinder is controlled by approach switch.
Good effect of the present utility model is: check valve assembling mode changes formal dress into by upside-down mounting, and while avoiding assembling, spring base 180 degree upsets, prevent the one-way valve spring neglected loading and laterally place, thereby has further improved the stability of product quality.Simultaneously, due to the use of cylinder and approach switch, realize press-fiting automation, improved greatly production efficiency.
The accompanying drawing explanation
Fig. 1 is the schematic diagram of spring base and spring structure.
Fig. 2 is original inverted structure schematic diagram.
Fig. 3 is the utility model example structure schematic diagram (having placed the spring base state).
Fig. 4 is the utility model example structure schematic diagram (having placed spring base and plunger state).
Fig. 5 is the press mounting structure schematic diagram.
The specific embodiment
Embodiment:
During use, at the interior placement spring 1 of spring base 2, then spring base 2 is placed in the shrinkage pool 6 of thin section 4 upper ends 5 of positioning seat 3, the end face of shrinkage pool 6 is just in time held the bead of spring base 2, and what make that spring base 2 places is very stable.
Place again steel ball 7 on spring base 2.
Place again plunger 8.
Because the external diameter of the internal diameter of positioning sleeve 9 and thin section 4 lower ends 10 is identical, and plunger 8 is just put in annular spaces 11, this just met the concentricity of spring base 2 and plunger 8 and assembly precision requirement.
The thick section 12 of positioning seat is placed on slide block 13, promotes slide block 13 and draws close approach switch 14.Approach switch 14 sends signal, magnetic valve action, cylinder 15 stretches out, drive ram 16 by spring base 2 with together with plunger 8 is fitted in.
