Description

Crankshaft eccentric is apart from measuring cubing

Technical field

The utility model relates to a kind of cubing, and especially a kind of crankshaft eccentric is apart from measuring cubing.

Background technology

Cubing is the instrument that is used to control the product various sizes in the commercial production, be applicable to the product of production in enormous quantities, good cubing can improve the work efficiency that product detects, and the qualification rate of product is also had better controlled, and therefore the design of various cubings seems important especially.The effect of bent axle is that the thrust that connecting rod transmits is become Power of Spin is moment of torsion, passes to gearing through bent axle, flywheel; Drive camshaft, fan, cooling-water pump; Other device work such as hydraulic oil pump, so the testing of bent axle is important especially.State's inside crankshaft finished product eccentric throw detects generally and detects based on saddle rule now, the personal error that the efficient that detects with saddle rule is very low, increase during testing product is very big and sense cycle a collection of product is very long, directly influence the time of product export, thereby influences sales volume.Also have at present and use eccentric cubing, but all can only detect single bent axle, product variety is many just need to come the suitable cubing of specialized designs according to every kind of product, every kind of bent axle of needs all is equipped with the crankshaft eccentric of oneself apart from test measuring device, the expense that has so just increased the test measuring device design and made has improved production cost greatly.

Summary of the invention

At the defective that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of crankshaft eccentric of any eccentric arm bent axle size in the accurate detection tool range that can make things convenient for apart from measuring cubing.

In order to achieve the above object, the utility model is to adopt the crankshaft eccentric of following structure to solve apart from measuring cubing, a kind of crankshaft eccentric is apart from measuring cubing, comprise chain-wales, two V-type framves, two guide rods, crossfoot, two locking members and clock gauge, movablely on the described chain-wales be fixed with two V-type framves, be symmetrically arranged with circular groove on described two V-type framves, described two guide rods are movable to be set in the via of V-type frame, movable being fixed on two guide rods behind the locking member all passed at the two ends of described crossfoot, what described two locking members were movable respectively is sleeved on two guide rods, in the movable via that is fixed on the crossfoot of described clock gauge.The upper end of V-type frame has xsect and is circular vertical via.

Two guide rods and chain-wales are vertically arranged, and the axle center of described two guide rods is positioned at same perpendicular, allow measure more accurate.

Locking member is positioned at V-type frame top, this locking member is provided with the adjusting bolt, can adjust the position of crossfoot according to the diameter of axle size of bent axle at vertical direction, simultaneously also can be according to the distance between length adjustment two V-blocks of bent axle, tighten the adjusting bolt after adjusting the position, guarantee stably bent axle to be detected in the position of the best.

Clock gauge is movable to be fixed on two crossfoots between the guide rod, can adjust the position easily according to the survey position.

The utility model crankshaft eccentric apart from the beneficial effect of measuring cubing is: can effectively measure any eccentric arm bent axle in range, the cubing various piece can detect the needs assembly unit according to different bent axles and use, and saves the design and the manufacturing cost of a large amount of single test measuring devices.Simultaneously, also improved the efficient of product testing.

Description of drawings

The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:

Fig. 1 is that crankshaft eccentric is apart from the front view of measuring cubing;

Fig. 2 is the A face view of Fig. 1;

Fig. 3 is the left view of Fig. 1;

Fig. 4 is the crankshaft structure synoptic diagram.

Embodiment

Disclosed all features in this instructions, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.

Disclosed arbitrary feature in this instructions (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of crankshaft eccentric is apart from measuring cubing, comprise chain-wales 6, two V-type framves 8, two guide rods 2, crossfoot 3, two locking members 10 and clock gauge 4, movablely on the chain-wales 6 be fixed with two V-type framves 8, be symmetrically arranged with circular groove on two V-type framves 8, with two of bent axle respectively correspondence be placed on the circular groove, two guide rods 2 are movable to be set in the via of V-type frame 8, movable being fixed on two guide rods 2 in locking member 10 backs all passed at the two ends of crossfoot 3, can change the position of crossfoot 3 simply and easily with respect to guide rod 2, the position that the different needs of bent axle detects is measured, two movable respectively being sleeved on two guide rods 2 of locking member 10 are in the clock gauge 4 movable vias that are fixed on the crossfoot 3.

The upper end of V-type frame 8 has xsect and is circular vertical via, and this vertical via is to allow the guide rod that has installed guide pillar head 1 pass.

Two guide rods 2 are vertically arranged with chain-wales 6, and the axle center of described two guide rods 2 is positioned at same perpendicular.

Locking member 10 is positioned at V-type frame 8 tops, and this locking member 10 is provided with regulates bolt 9.

Clock gauge 4 movable being fixed on two crossfoots 3 between the guide rod 2, this clock gauge specifically is to fix the position by the set nut on the crossfoot 7.

Detecting crankshaft eccentric apart from a size, because a size can't directly be measured, therefore generally all is to measure the b size, obtains a size indirectly.This overlaps the measurer that eccentric cubing is exactly a special detection b size.

On platform, adjust the distance of two V-type framves 8, unclamp the adjusting bolt 9 on the locking member 10, move the distance between two locking members 10, make crossfoot 3 can measure the length of this bent axle, regulate the double-screw bolt 11 on the V-type frame 8, guide rod 2 can not rotated in the vertical via of V-type frame 8.The crankshaft length scope that this cubing can be measured is 240-505mm.The angle of the V-type frame 8 in this cubing can be made as required, and its scope is 30 °-180 °.

[0022]Select the par 5 of this bent axle size, equally, the adjusting bolt 9 that unclamps on the locking member 10 slides up and down suitable position on guide rod 2, it is good with the stationkeeping of clock gauge 4 to tighten set nut 7, select for use again with the supporting par 5 of bent axle and make clock gauge 4 zeroings, remove par 5, put the bent axle of being surveyed.According to the model of bent axle, the length range of par 5 is 101-225mm.

[0023]Two V-type framves 8 of measurer are placed on I, II two king journals, clock gauge 4 crowns are on A connecting rod neck, axially rock measurer slightly at bent axle, watch the clock gauge numerical value change, its maximal value is the connecting rod neck b size of bent axle, and the difference of its maximal value b size and par b size can obtain the difference between a size and the standard through converting.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
