Abstract
The utility model relates to a special purpose screw used for adjusting gap of internal combustion motor jet, which is composed of a head 1, a screw rod 2 and a tail end 3. The head has a dial, and the dial is divided into 20 equal parts, and the head also has three notches. The scale screw can be adjusted directly with a screwdriver and can complete the gap adjusting work rapidly and easily, yet needs no feelers or other measuring tools.
Description
The utility model relates to a kind of Full dog point socket set that the explosive motor valve clearance is adjusted that is used for.
At present, installing the screw (also being jackscrew) that is used to adjust the valve clearance on the explosive motor rocking arm is the general standard part.When adjusting the valve clearance, must come the appropriateness of detector gap adjustment by means of clearance gauge or other measuring tool with it.Its shortcoming is a trivial operations, inefficiency, and poor accuracy.
The purpose of this utility model provides a kind of improved scale and adjusts screw, utilizes it can use clearance gauge and other measuring tools, directly adjusts this scale screw with screw, finishes engine valve clearance adjustment work rapidly, easily.
The utility model is to realize like this.It is similar on overall structure to existing adjustment screw, still is made of head 1, screw rod 2, afterbody 3 three parts.Its improvements are, head has the garden dish of scale sign, are equivalent to 1 pitch (t=1mm) of screw thread one week, are divided into 20 five equilibriums along garden week, and then to represent pitch precession value be 0.05mm to the per unit scale.When the operator inserts the cutting of this adjustment screw head central authorities Cylinder with screw-driver, can determine the number of division of dial rotation according to the working clearance value of various internal-combustion engine inlet and outlet doors, and rapidly, adjusted easily and accurately.With the Q492 h type engine h is example, and its adjustment process concrete steps are as follows: at first, and with the loosening hexagonal locking nut (also claiming back of the body cap) that is fixed on this adjustment screw of spanner; Rotate to adjust screw with screw-driver, when valve rocker just contacts with the valve stem tail end till; Again locking nut is rotated to the arbitrary crest line that makes its hexagonal when relative with this adjustment screw head 1 dial zero line breach till; If adjust the intake valve gap, then screw is adjusted in rotation, makes its head 1 dial forward the 4th graduation line (being the position of first breach) to, if adjust emission valve clearance, then forwards the 5th graduation line (i.e. the position of second breach) to; Keep to adjust screw and maintain static, the rotation lock nut is locked it, in case it is loosening to adjust screw during air-stop gate work.When other type valve clearancies were adjusted, operating method was same as described above, just adjusted the scale value difference of screw rotation, and promptly various types by the corresponding adjustment of scale value of regulation separately with carrying out.
The engine valve clearance of this kind band scale is adjusted screw and is had applied range, simple to operate, and easy to use, regulate the speed fast, precision advantages of higher are suitable in practicality and promote.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is its left view (a head dial schematic representation).
The utility model is simple in structure, and is easy to implement.Its material and machining accuracy all do not have specific (special) requirements, and material is a plain carbon steel, and head 1 dial can adopt special die adding man-hour, and graduation line and numeral is one time punching molded.With the Q492 h type engine h is example, and its each several part size and processing request are as follows: screw total length 33mm.Head 1 dial external diameter 18mm, thick 1mm, scale are 20 five equilibriums, 3 breach respectively are 45 °; The Cylinder external diameter of head 1 central zone cutting is 8mm, high 5mm, groove width 2mm, dark 4mm.The long 20mm of screw rod 2 helical thread portions, the screw thread specification is M8 * 1-6H.Tail end 3 is the R3 hemisphere, the processing roughness
It is identical with it that screw structural is adjusted in the valve clearance of other types, only needs corresponding varying sized getting final product.
