Embodiment Construction
[0019] Attached figure 1 Schematic diagram of parts and structure before assembly of motorcycle engine crankshaft assembly, attached figure 2 It is a schematic diagram of the parts and structure of the motorcycle engine crankshaft assembly after assembly. In the figure, 1 is the left crank, 2 is the right crank, 3 is the crank pin, 4 is the connecting rod, 5 is the left bearing, 6 is the right bearing, and 7 It is a timing gear. It can be seen from the figure that the crankshaft assembly includes a left crank, a right crank, a crank pin, a needle bearing, a connecting rod, a left bearing, a right bearing and a timing gear. The left crank and the right crank are press-fitted through interference fit with the crank pin. The connecting rod is press-fitted on the crank pin through the needle bearing, and the left bearing, the right bearing and the timing gear are also fixedly mounted on the crank rod by press-fitting to form a crankshaft assembly. In the assembly process of the cr...

In order to resolve the problem that in the existing technology, after an engine crankshaft assembly is assembled, parallelism of a connecting rod small end hole is difficult to inspect, the invention provides an inspection device and inspection method for the parallelism of the connecting rod small end hole of the engine crankshaft assembly. In the inspection device for the parallelism of the connecting rod small end hole of the engine crankshaft assembly, V-shaped grooves are formed in the upper portions of two V-shaped supports and the two V-shaped supports are fixed on a baseplate parallelly, the space distance between the two V-shaped supports are the same with the space distance between two bearings of a crankshaft assembly, a groove is formed in a connecting rod support and the connecting rod support is fixed on the baseplate which is located right in the front of the V-shaped supports, the width of the groove is larger than the thickness of the connecting rod, and a dial indicator is fixed on one side of the front of the connecting rod support. The inspection device for the parallelism of the connecting rod small end hole of the engine crankshaft assembly is used for inspecting the parallelism of the connecting rod small end hole of the crankshaft assembly which is assembled, and has the advantages of being convenient to operate, accurate in result, good in repeatability, low in manufacturing cost, and suitable for being popularized.
Description
Technical field [0001] The invention relates to a technology for detecting the parallelism of a connecting rod small-end hole of an engine crankshaft assembly, in particular to a test tool and a detection method for the parallelism of the connecting rod small-end hole of an engine crankshaft assembly. Background technique [0002] The function of the motorcycle engine crankshaft assembly is to convert the linear reciprocating motion of the piston into a rotary motion, output torque, and drive the external working device and the control mechanism such as the valve mechanism, the ignition mechanism and the speed regulating mechanism that are matched with it. [0003] Generally, motorcycle engine crankshaft assembly (hereinafter referred to as crankshaft assembly) includes left crank, right crank, crank pin, needle bearing, connecting rod, left bearing, right bearing and timing gear. The left crank and the right crank pass through and the crank The pin’s interference fit is connected ...
