Abstract
The invention relates to a detection tool for the valve line depth of an air valve seat ring for a cylinder cover of an engine. The detection tool comprises a lever indicator, an indicator clamp and a positioning surveying rod, wherein the lever indicator is arranged on the indicator clamp; the positioning surveying rod is a cylindrical rod; the upper part of the positioning surveying rod is provided with a handle, and the lower part of the positioning surveying rod is provided with a positioning guide rod; the positioning guide rod is matched with a guide pipe hole on the cylinder cover in a positioning way; the middle part of the positioning surveying rod is provided with a disc-shaped boss; the measuring head of the lever indicator is jointed with the top surface of the boss; the lower part of the boss is provided with a conical platform; and the conical surface of the conical platform is matched with the valve surface of the air valve seat ring. By adopting the detection tool, the valve line depth of the air valve seat ring for the cylinder cover can be detected quickly and reliably, the detection cost is reduced, and the accuracy for detecting the depth value of the valve line of the air valve seat ring for the cylinder cover can be up to 0.01 millimeter. The detection tool can be applied to quality control and management of the processing line of a cylinder cover machine. The detection tool has a reasonable design and a simple structure, and is convenient to operate and use.
Description
Technical field
The invention belongs to technical field of internal combustion engines, be specifically related to a kind of testing tool of the gasoline engine valve retainer firewire degree of depth.
Background technology
The height of the valve retainer hole machining precision of cylinder cap directly influences sealing, dynamic property and the reliability of engine.Present existing head valve seat ring firewire depth detection method of application is that three coordinates detect, and this method is long detection time, low precision.
Summary of the invention
For the accuracy of detection that improves the valve retainer hole with shorten detection time, the present invention provide a kind of on production line the manual testing tool of the detection of engine head valve seat ring valve line degree of depth.
The technical solution that realizes above-mentioned purpose is following:
The testing tool of the engine cylinder cover valve retainer firewire degree of depth comprises lever indicator, table folder and location measuring staff; Said table folder is L shaped plate, and the one of which middle side part is provided with the lever hole, and the lever of lever indicator is plugged in the lever hole of table folder; The table folder on top, lever hole is provided with positioning screw hole, cooperates in the positioning screw hole to be provided with holding screw, and the lower end of holding screw contacts with the lever of lever indicator; Said location measuring staff is a cylindrical bar; Top is handle, and the bottom is a location guide, and location guide is located with the guide hole on the cylinder cap and cooperated; Measuring staff middle part, location is provided with discoid boss; The measuring head of lever indicator and said boss end face are fitted, and the bottom of said boss is the frustum of a cone, and the circular conical surface of the said frustum of a cone cooperates with the Fa Er face of valve retainer.Useful technique effect of the present invention is: can realize quickly and reliably detecting the valve line degree of depth of head valve seat ring, reduce and detect cost that the depth value precision that detects head valve seat ring firewire can reach 0.01mm.Can be used for the quality control and the management of cylinder cap machine work line.The present invention is reasonable in design, and is in conjunction with simple, easy for operation.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the vertical view of Fig. 1.
Sequence number among the last figure: location measuring staff 1, discoid boss 1.1, handle 1.2, location guide 1.3, table folder 2, lever indicator 3.
Embodiment
Below in conjunction with accompanying drawing, the present invention is done explanation further through embodiment.
Embodiment:
Referring to Fig. 1 and Fig. 2, the testing tool of the engine cylinder cover valve retainer firewire degree of depth comprises lever indicator 3, table folder 2 and location measuring staff 1.Table folder 2 is a L shaped plate; The one of which middle side part offers the lever hole, and the lever of lever indicator 3 is inserted in the lever hole of table folder, and the opposite side bottom surface is big plane; Offer positioning screw hole on the table folder 2 on top, lever hole; Cooperate in the positioning screw hole holding screw is housed, the lower end of holding screw contacts with the lever of lever indicator, and lever indicator 3 is fixed on the table folder 2.The location measuring staff is a cylindrical bar; Top is handle 1.2, and the bottom is a location guide 1.3, and location guide 1.3 cooperates with the guide hole location; The middle part is discoid boss 1.1; The boss end face is the gauge outfit mating surface of lever indicator, and the bottom is the frustum of a cone, and the circular conical surface of the frustum of a cone cooperates with the Fa Er face of valve retainer.
When being used to detect, engine cylinder cover to be detected is lain in a horizontal plane on the monitor station, valve retainer hole one side level upwards.
Hand-held table folder 2, the big plane that table is pressed from both sides the bottom is placed on the cylinder cap fire power face.Location guide 1.3 ends of locating measuring staff 1 are put in the cylinder head guide pipe hole to be positioned; After accomplish the location; Hand-held table folder 2 horizontal directions remain unchanged, lever indicator 3 measuring head applying cylinder cap fire power face, and this moment, the reading of lever indicator 3 returned to zero; Again according to before method read the fit reading of measuring staff middle part, location boss 1.1 end faces of lever indicator 3 gauge outfits, reading and be the difference of the valve line actual grade and the theoretical degree of depth.
After detecting in a manner described, the depth value precision of head valve seat ring firewire can reach 0.01mm.And detected value is very stable.The product precision is well controlled.
Claims (1)
