Abstract

A kind of automobile engine crankshaft center pit cubing structure, it comprises clamp base, clamp head, and be located at the meter in clamp head, its technical essential is: two corresponding clamp head that arrange are fixed on the two ends of clamp base, near being respectively arranged with a bent axle V-type bracing frame in the clamp base of clamp head, this bent axle V-type bracing frame by: be connected in clamp base and with the guide of inner slide V-type slide block and be arranged on the lift adjustment bolt composition of V-type slide block bottom.The utility model can regulate bent axle V-type bracing frame highly owing to being provided with one in clamp base, like this, just can change according to the king journal of different model bent axle, by adjusting the height of bent axle V-type bracing frame, to adapt to the accurate measurement that different main neck changes.

Description

Automobile engine crankshaft center pit cubing structure
Technical field
The utility model relates to automotive engine component detection technique field, specifically a kind of automobile engine crankshaft center pit cubing structure.
Background technology
Bent axle is the important precise part of engine, and bent axle is one of core component of engine.As the driving source output block of engine, it is bearing complicated alternate load, the gas force, reciprocating mass inertial force, rotation and the moving centrifugal intertia force that periodically constantly change as being subject in the course of work.Constantly bearing and reversing and horizontal, extensional vibration, bearing tensile, compressive, bending transverse stress.Therefore bent axle must have enough intensity, rigidity, toughness and wearing quality and high machining precision.Its machining precision will directly affect the life-span of bent axle and even engine, and bent axle is one of the most difficult processing parts in engine, process complex procedures, and the useless rate of work is very high.
Central hole of the crankshaft is except affecting the mass distribution of bent axle, its importance is also that it is the important smart benchmark of Crankshaft Machining, in whole crankshaft processing technology, play a part to form a connecting link, the size of the center pit conical surface and surface roughness affect the crudy of postorder operation.In postorder operation, some operations are using center pit as benchmark is as axial location.If the size of center pit is unstable, can make troubles to the processing of these operations.
Traditional measurement crankshaft center hole dimension generally all adopts vernier caliper to coordinate steel ball mode to measure again, due to measuring error measuring center hole dimension accurately.Afterwards, the cubing that manufacturing enterprise adopts is to utilize king journal location, the degree of depth in band special table depth gauge measuring center hole, although more traditional crankshaft center hole measurement has had larger improvement, its kind that is only applicable to single specification detects, in the time running into the kind of different size, due to the king journal size difference of bent axle, this fixture just cannot accurately be measured, and needs to redesign to manufacture new cubing, has so just caused the raising of production cost.
Summary of the invention
The purpose of this utility model is to provide a kind of automobile engine crankshaft center pit cubing structure that can simultaneously measure different size crankshaft center hole dimension.
The purpose of this utility model is achieved by the following technical solution: it comprises clamp base, clamp head, and be located at the meter in clamp head, it is characterized in that: two corresponding clamp head that arrange are fixed on the two ends of clamp base, be respectively arranged with a bent axle V-type bracing frame near in the clamp base of clamp head, this bent axle V-type bracing frame by: be connected in clamp base and with the guide of inner slide V-type slide block and be arranged on the lift adjustment nut composition of V-type slide block bottom.
Described bent axle V-type bracing frame is to be supported on the position of main bearing journal.
The utility model can regulate bent axle V-type bracing frame highly owing to being provided with one in clamp base, like this, just can change according to the king journal of different model bent axle, by adjusting the height of bent axle V-type bracing frame, to adapt to the accurate measurement that different main neck changes.
The utlity model has rational in infrastructurely, easy to operate, improve and measure efficiency, can adapt to the testing requirement of similar model different size bent axle, reduced production cost.
Brief description of the drawings
Fig. 1 is structural representation sketch of the present utility model;
Fig. 2 is the plan structure schematic diagram in Fig. 1;
Fig. 3 is that A-A in Fig. 1 is to cross-section structure simplified schematic diagram.
Below in conjunction with accompanying drawing and by example, the utility model is described in further detail; but following example is only the utility model example wherein; do not represent the rights protection scope that the utility model limits, rights protection scope of the present utility model is as the criterion with claims.
Specific embodiments
example 1
Shown in Fig. 1-3, in figure 1 is clamp base, 2 is clamp head, 3 for being arranged on the meter 3 in clamp head 2, two corresponding clamp head 2 that arrange are fixed on the two ends of clamp base 1, near being respectively arranged with a bent axle V-type bracing frame 6 in the clamp base of clamp head, this bent axle V-type bracing frame 6 by: be connected in clamp base 1 and with the guide 601 of inner slide 602, V-type slide block 605 and the screw rod 603 and the lift adjustment nut 604 that are arranged on V-type slide block 605 bottoms form.
Measuring process: in the time that measured bent axle specification is identical, as long as measured workpiece bent axle is placed on V-type bracing frame 6, the motion by handle 5, at this moment just can be by being located at meter 3 sense datas at two ends by tested bent axle 4 Work-sheet pressings.
While measuring the bent axle of new model, because the journal size of crank spindle 7 changes, as shown in (Fig. 3): by the height change of adjusting nut 604, V-type slide block 605 just can move up and down at guide 601, change to adapt to different king journals, finally again handle 5 is compressed, just can measure the degree of depth of the central hole of the crankshaft of different model by the meter 3 at two ends, easy to adjust, raise the efficiency, the testing requirement that can adapt to similar model bent axle, has reduced production cost.
