Abstract

The utility model relates to a test checking fixture for a connecting rod sleeve of an automobile engine. The test checking fixture comprises an upper clamp plate and a lower clamp plate, wherein the upper clamp plate is connected with an upper joint, and the lower clamp plate is connected with a lower joint. The upper clamp plate and the lower clamp plate are connected into an entirety through a tested connecting rod, a large ferrule on the tested connecting rod is clamped and connected onto the upper clamp plate through a connecting piece, and a small ferrule is clamped and connected onto the lower clamp plate. When the maximum rupture tension at the large ferrule and the small ferrule of two ends of the connecting rod is tested, the large ferrule and the small ferrule of the two ends of the connecting rod need to be respectively clamped and overhung into the upper clamp plate and the lower clamp plate, and the connecting rod is connected with the upper clamp plate and the lower clamp plate into a whole through bolts, shafts and positioning blocks; the tension applied by a two-way tensile machine directly acts on the two ends of the connecting rod through the upper clamp plate, the lower clamp plate, the shafts, the positioning blocks and the bolts; and at the moment, two ends of the connecting rod are subjected to the maximum force, become the weakest links of the connecting rod and are ruptured firstly. The born maximum tension, namely the destructive-power rupture tension, can be measured, so that the reliable data is provided for the reasonable design of strength of the connecting rod. The using safety and reliability of the connecting rod are ensured. The measurement operation is simple and convenient, and the measurement is accurate, reliable and intuitive.

Description

Connection rod of automobile engine cover test cubing
Technical field
The utility model relates to a kind of tensile test anchor clamps, and particularly the connecting rod to motor car engine carries out the connection rod of automobile engine cover test cubing that destructive tensile fracture detects use.
Background technology
Connection rod of automobile engine is the movement parts of transferring power, and the to-and-fro movement of piston is transformed into rotatablely moving of bent axle, the integral body that connecting rod is connected into by the big or small lasso at two ends and middle shaft slyness; The different parts of connecting rod not only shape is different, stressed state also different, the big or small lasso at generalized case lower link two ends is stressed bigger; Middle shaft position is stressed slightly little, normally moves for guaranteeing motor car engine, necessarily requires its intensity of quality, the good rigidity of connecting rod indeformable; Also must carry out check and analysis to the stressing conditions of connecting rod each several part; But the existing stressed detection of connecting rod, adopt by two-way puller system carried out maximum is measured in two-way pulling up to fracture holding capacity to it more, because of the direct pull connecting rod detects; Make connecting rod only stressed, so measure inaccurate at upper and lower pulling point single-point.
Summary of the invention
The utility model technical matters to be solved is: a kind of connection rod of automobile engine cover test cubing is provided; Different parts to connecting rod makes a strength test; Maximum tensile fracture in the time of accurately testing lasso place, connecting rod two ends destruction, thus reliability, the security that connecting rod part uses guaranteed.
The utility model addresses the above problem the technical scheme that is adopted: connection rod of automobile engine cover test cubing; Comprise train wheel bridge that is connected with top connection and the lower plate that is connected with lower sub; Tested connecting rod connects into integral body with upper and lower clamping plate; And with web member the big lasso on the tested connecting rod is clamped and connected on train wheel bridge, little lasso is clamped and connected on lower plate.
Compared with prior art; The advantage of the utility model is: this test cubing is when the maximum tensile fracture at size lasso place, test connecting rod two ends; Need with the large and small lasso at connecting rod two ends respectively clamping be suspended in the upper and lower clamping plate, with latch, axle, locating piece connecting rod and upper and lower clamping plate are connected into integral body again, the pulling force that two-way puller system applies acts directly on the two ends of connecting rod through upper and lower clamping plate and axle, locating piece, latch; At this moment the stressed maximum in the two ends weakest link that becomes connecting rod is at first broken; The maximum pull that at this moment connecting rod can bear is exactly that the destructive power tensile fracture just can be measured, and for the appropriate design of connecting rod strength provides reliable data, thereby has guaranteed security and the reliability that connecting rod uses; This cubing measuring operation is simple and convenient, and measures accurately reliable, directly perceived.
Description of drawings
The structural representation of Fig. 1, the utility model (cut-open view).
The left view of Fig. 2, Fig. 1.
Embodiment
Embodiment to the utility model further describes below in conjunction with accompanying drawing.
Upper and lower clamping plate 2,7 are identical U-shaped, on its bottom screw are arranged, and connect upper and lower joint 1,8 with nut thread, and corresponding through hole is arranged on the two side of opening part.
The last through hole of the large and small lasso 3-1 at connecting rod 3 two ends, 3-3 is vertical each other, and the axle center is on same straight line, and shaft 3-2 midsection is shaped as I-shaped.
Web member adopts fixed block 4, axle 5, latch 6, also can be other structure, and fixed block has the groove on convex tendon and the big lasso 3-1 of the connecting rod inwall to be complementary on the 4 middle neighborings that have through hole to be connected with axle 5, fixed block 4.
Utilize the upper and lower joint 1,8 on it to be separately fixed on the upper and lower measuring junction of two-way puller system on upper and lower clamping plate 2,7.
During measurement; Through hole and through hole on the fixed block 4 and the through hole on another sidewall on train wheel bridge one sidewall pass with axle 5 then successively with the big lasso internal fixation of fixed block 4 embedding connecting rods in elder generation, the upper end of connecting rod are suspended in midair be clamped in the train wheel bridge 2; Simultaneously latch 6 is also passed the through hole on lower plate one sidewall successively; Through hole on the little lasso, the through hole on another sidewall is clamped in the suspention of the lower end of connecting rod in the lower plate 7.
The big or small lasso that is the connecting rod two ends is clamped in the upper and lower clamping plate 2,7 through axle 5, latch 6 suspentions respectively.
As long as at this moment start two-way puller system; Pulling force just is directly delivered on the large and small lasso at connecting rod two ends through upper and lower clamping plate 2,7 and axle 5, fixed block 4, latch 6; Simultaneously the stressed maximum of these two ends institute becomes the weakest link on the connecting rod, therefore at first ruptures here, and the maximum pull that large and small lasso 3-1,3-3 can bear is exactly that the destructive power tensile fracture just can be measured; And the maximum tensile fracture when the puller system instrument demonstrates connecting rod and destroys, test is simple, directly perceived, convenient.
