Description
Technical field
The present invention relates to a kind of measurement mechanism, especially a kind of engine bearing shell radial height measurement mechanism.
Background technology
Produce the engine shaft watt-hour in enormous quantities, needing the high and external diameter binding face of real-time detecting bearing shell radius in the production.At present, used bearing shell radial height measurement mechanism, accepted standard watt only requires that according to national Specification its basic size is consistent with the basic size of tested bearing shell, and therefore for easy to process, bearing shell commonly used is measured with standard and watt is processed into as shown in fig. 1,1 is standard watt, it is to be processed on the solid ball of fixed diameter, with solid ball be one, 2 is master die, this standard watt is standard semicircle shape, the no bullet amount of rising.But reality use with the process of measuring check in, if standard watt just with the consistent size of bearing shell, along with the increase of service time of standard watt, standard watt is easy to generate interior bending deformation, the gap between formation standard watt and the master die.The existence of standard watt deflection E makes its master die inwall of can't fitting fully, thereby can't accurately proofread the milscale zero-bit.Master die is because frequent measurement bearing shell simultaneously, its inwall weares and teares easily, if but the inner wall abrasion amount is in the margin tolerance that allows, it still can be used to measure, but general standard watt be because of can not touching the master die inwall of wearing and tearing, so can't determine to use the master die after a period of time whether to have measuring accuracy.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of bearing shell radial height measurement mechanism, its accepted standard is watt more near the bearing shell virtual condition, it has certain bullet amount of rising, and can guarantee the precision of measurement, and has the ability of the test stone mould degree of wear.
In order to solve the problems of the technologies described above, the utility model provides bearing shell radial height measurement mechanism, comprise the master die that is fixed on the worktable, have semi-circular recesses on the master die, master die top one side is a fixed pressuring plate, opposite side is a dynamic pressure plate, the clock gauge gauge outfit is near dynamic pressure plate and Height Adjustable, also be provided with a standard watt in the described semi-circular recesses, described standard watt is semicircular arc, the outside surface and the semi-circular recesses face of described standard watt fit, and under free state, the external diameter of standard watt opening part is greater than the diameter of semi-circular recesses.The virtual condition of the standard of this kind structure watt more approaching bearing shell to be measured, have certain bullet amount of rising, even therefore the master die inwall has wearing and tearing in to a certain degree, standard watt outer wall also can fit tightly with master die, thereby accurately proofread the zero-bit of milscale, guarantee the precision that bearing shell is measured.
Preferably, described standard watt is made with die steel material, has higher fatigue resistance.
Bearing shell radial height measurement mechanism of the present utility model; the measuring accuracy height; and ability with test stone mould degree of wear; when master die has wearing and tearing; as long as standard watt can fit tightly with the master die inwall; then this master die can also use, and when standard watt can't fit tightly with the master die inwall, then needs to change master die.

Embodiment
Bearing shell radial height measurement mechanism as shown in Figure 2, comprise the master die 2 that is fixed on the worktable, have semi-circular recesses 6 on the master die 2, master die 2 tops one side is a fixed pressuring plate 3, opposite side is a dynamic pressure plate 4, clock gauge 5 gauge outfits are near dynamic pressure plate 4 and Height Adjustable, also be provided with a standard watt 1 in the semi-circular recesses 6, this standard watt 1 is semicircular arc, and the outside surface and the semi-circular recesses face of standard watt 1 fit, under free state, the external diameter of standard watt 1 opening part is greater than the diameter of semi-circular recesses 6, and as shown in Figure 3, B is the external diameter of standard watt 1 opening part under the free state, A is the nominal outer diameter of standard watt, also is the diameter of semi-circular recesses 6.The virtual condition of the standard of this kind structure watt more approaching bearing shell to be measured, have certain bullet amount of rising, even master die 2 inwalls have wearing and tearing in to a certain degree, standard watt outer wall also can fit tightly with master die, thereby accurately proofread the zero-bit of milscale, guaranteed the precision that bearing shell is measured.
Preferably, described standard watt 1 a usefulness die steel material is made, and has higher fatigue resistance.
When using bearing shell radial height measurement mechanism measurement bearing shell radial height shown in Figure 2, at first clock gauge is carried out than zero-bit, step is as follows: 1) standard watts 1 one is put into master die 2 fixed pressuring plates 3 belows, dynamic pressure plate 4 is pushed down standard watt 1 other end then, tighten the screw on the dynamic pressure plate 4, standard watt 1 is fixed in the semi-circular recesses 6 in (the imitation bearing shell is in in-engine stress) under certain pressure, fits with semi-circular recesses 6 faces; 2) master die 2 is placed under the dial holder, the probe of clock gauge refers on standard watt 1; 3) reading of observation clock gauge; 4) height of adjustment clock gauge makes clock gauge that certain measurement surplus all be arranged up and down; 5) watchcase of rotation clock gauge makes zero the pointer of clock gauge; 6) unscrew the nut of dynamic pressure plate 4, remove dynamic pressure plate 4, taking-up standard watt 1 is finished the zero-bit verification of clock gauge.At this moment, bearing shell to be measured can be put into master die, repeating step 1) to 3), finish the radial height of bearing shell to be measured and measure.After measuring a period of time, can repeat said method again, once more clock gauge be carried out the zero-bit verification.
When master die has certain wearing and tearing, as long as standard watt still can fit tightly with the master die outer wall, then still can use earlier this standard watt to milscale than zero-bit, utilize this master die to measure bearing shell radial height to be measured then.When standard watt can't fit tightly with the master die inwall, then need to change master die.
The utility model bearing shell radial height measurement mechanism because of use has the standard watt of the bullet amount of rising, not only can guarantee the precision measured, and have the ability of test stone mould wearing and tearing, higher fatigue resistance.Need not frequently to change standard watt in the use, reduced cost, guarantee bearing shell product radial height measuring stability.
More than just utility model has been carried out exemplary explanation, specific implementation of the present utility model is not limited thereto.The insubstantial modifications that any employing design of the present utility model and technical scheme are carried out is all within protection domain of the present utility model.
