Abstract
A detecting tool for detecting the symmetry degree of a segmenting face of a large head end of a connecting rod is disclosed and comprises a dial gauge (1) and a leveling ruler (2). A gauge rod (11) of the dial gauge (1) is mounted on the leveling ruler. The moving direction of a measuring head (12) of the dial gauge is perpendicular to a plane of the leveling ruler. Two guide rods (4) are vertically mounted on the leveling ruler and are positioned on two sides of the gauge rod symmetrically. One end of the gauge rod runs through the center of a rectangular positioning block (3). One end of each guide rod (4) is plugged in a guide hole (31) of the positioning block in a matching manner. A spring (6) is arranged between the upper surface of the positioning block and the lower surface of the leveling ruler. The length of the positioning block is two thirds of the diameter of a large head hole of the connecting rod (7). The width of the positioning block is slightly smaller than the distance between two end faces of the large head end of the connecting rod. The detecting tool is simple in structure and convenient to use, and the symmetry degree of the segmenting face of the large head end of the connecting rod can be accurately detected.
Description
Technical field
The present invention relates to a kind of cubing detecting big end end divisional plane symmetry, it includes a leveling ruler and the dial gauge being arranged on leveling ruler.
Background technology
The stub end of connecting rod is by being connected in shaft upper half circle and connecting rod cap forms, when forging, they are integrally formed, after the both ends of the surface of the both ends of the surface of stub end of connecting rod and the little head end of hole and connecting rod and aperture cross processing, need to separate stub end, the half bore that technology requirement is shaft upper half circle should be equal with the radius of the half bore of connecting rod cap, it is therefore desirable to designs a kind of cubing detecting big end end divisional plane symmetry.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of cubing detecting big end end divisional plane symmetry, to detect big end end divisional plane symmetry easily and accurately.
This cubing includes dial gauge 1, leveling ruler 2, and the table bar 11 of dial gauge is arranged on leveling ruler, and the plane measuring 12 moving direction and leveling ruler of dial gauge is perpendicular; It is characterized in that, leveling ruler is vertically provided with two guide posts 4, guide post is symmetrically located at the both sides of table bar, one end of table bar is through the center of the locating piece 3 of rectangle, the one end fits ground of guide post inserts in the pilot hole 31 of locating piece, being provided with spring 6 between the upper surface and the lower surface of leveling ruler of locating piece, the length of locating piece is the 2/3 of connecting rod 7 big end hole diameter, and the width of locating piece is slightly less than the spacing between big end end both ends of the surface.
Leveling ruler is shelved on the divisional plane of connecting rod when using by this cubing, two seamed edges bottom locating piece contact with tie rod holes, the head of measuring of dial gauge is pressed on the surface of tie rod holes to read the radius of tie rod holes, measure the radius in the hole of shaft upper half circle and connecting rod cap respectively, the symmetry of big end end divisional plane can be determined. This detection tool structure symmetry that can determine big end end divisional plane exactly simple, easy to use.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the top view of Fig. 1, only draws connecting rod and locating piece in the figure.
Detailed description of the invention
In conjunction with accompanying drawing, the specific embodiment of the present invention is described.
A kind of cubing detecting big end end divisional plane symmetry, including dial gauge 1, leveling ruler 2, the table bar 11 of dial gauge is arranged on leveling ruler, and the plane measuring 12 moving direction and leveling ruler of dial gauge is perpendicular; Leveling ruler is vertically provided with two guide posts 4, guide post is symmetrically located at the both sides of table bar, one end of table bar is through the center of the locating piece 3 of rectangle, the one end fits ground of guide post inserts in the pilot hole 31 of locating piece, locating piece is provided with sleeve 5, sleeve is enclosed within table bar, it is provided with spring 6 between the upper surface and the lower surface of leveling ruler of locating piece, spring housing is on sleeve, the length of locating piece is the 2/3 of connecting rod 7 big end hole diameter, and the width of locating piece is slightly less than the spacing between big end end both ends of the surface.
For preventing locating piece from slipping from guide post, the bar portion of guide post one end is rotary with screw 8, locating piece is limited on the guide bar.
During use, locating piece is placed in the big end hole of connecting rod, the seamed edge at the length direction two ends of locating piece contacts with the hole portion of connecting rod, leveling ruler is pressed to the divisional plane of connecting rod, due to the effect of locating piece in the process flattening chi, making that leveling ruler is mobile on the divisional plane of connecting rod to be looked for, what can make dial gauge when leveling ruler is pressed on the divisional plane of connecting rod measures head and tie rod holes portion contacting correctly.
The big end hole processing of connecting rod has a range of error, the purpose of spring set between the upper surface and the lower surface of leveling ruler of locating piece is when the big end hole radius of connecting rod is inconsistent, the seamed edge at the two ends of locating piece is appointed can with the hole portion reliable contacts of connecting rod, it is ensured that in looking for accurately.
