Description
Technical field
The present invention relates to detection method and the device thereof of a kind of machinery inner chamber size, especially relate to detection device and the detection method of a kind of size of inner cavity of railway vehicle.
Background technology
Rolling stock is required to install coupler and draft gear, is used for alleviating train produced longitudinal force and impulsive force in running.Coupler and draft gear is arranged in the inner chamber of draw beam composition of rolling stock, and the size of this inner chamber is considered critical size, directly affects final success and installs coupler and draft gear.Inner chamber is made up of front draft lug (left), front draft lug (right), rear draft lug (left), rear draft lug (right), draw beam web (left), draw beam web (right), draw beam upper cover plate, draw beam lower cover assembly welding.Such as we export the railway freight-car of the U.S. vitals draw beam composition, need ensure all positions of inner chamber longitudinal size beNot only need to ensure that the distance that draw beam forms between front draft lug (left) and the rear draft lug (left) of homonymy isAnd the distance between front draft lug (right) and rear draft lug (right) isAnd need to ensure that the front draft lug (left) of draw beam composition heteropleural and rear draft lug (right) fore-and-aft distance (length direction) each other areAnd the fore-and-aft distance (length direction) that front draft lug (right) and rear draft lug (left) are each other is
Owing to the draw beam composition of outlet needs to assemble abroad coupler and draft gear, therefore must assure that draw beam inner chamber size, such guarantee client installs coupler and draft gear smoothly.
Existing technical scheme uses tape measure and angle square to measure inner chamber size.
The fore-and-aft distance between the same side front draft lug and rear draft lug is formed initially with tape measure draw beamDuring assembly welding, there is assembling deviation and welding deformation, and there is mismachining tolerance in front draft lug and rear draft lug accessory, therefore the distance between being likely to result in the front draft lug and the rear draft lug that are arranged on homonymy on draw beam web, the size of diverse location is different in vertical direction.We must use tape measure to choose at 5 the fore-and-aft distance between position measurement front draft lug (left) and rear draft lug (left) in vertical direction, and the fore-and-aft distance between front draft lug (right) and rear draft lug (right), to ensure that between homonymy front draft lug and rear draft lug, any position meetsDimensional requirement.
For the front draft lug (left) of heteropleural and rear draft lug (right) fore-and-aft distance (length direction) each other in draw beam composition inner chamber, and front draft lug (right) and rear draft lug (left) fore-and-aft distance each otherDirectly cannot be measured by tape measure, it is necessary to use two L300X300 angle squares and tape measure conjunction measuring.Such as when measuring front draft lug (left) and rear draft lug (right) fore-and-aft distance (length direction) each other, by one of them angle square while being placed on draw beam web (left), another side alignment front draft lug (left) side, another one angle square is placed on the draw beam web on opposite, another side alignment rear draft lug (right) side, then the distance between tape measure two angle square is used, it is simply that required distance.Due to welding deformation and the impact of draw beam web plane degree, often result in measurement inaccurate.Additionally this measuring method needs two people to coordinate and just can complete, and one of them people operates an angle square, and another person operates an other angle square.
But, there are problems in prior art:
(1) for the fore-and-aft distance between front draft lug (left) and the rear draft lug (left) of homonymy, and the fore-and-aft distance measurement between front draft lug (right) and rear draft lug (right), when measuring due to reality, this inner chamber three side sealing closes, and measurement difficulty, tape measure tilt to cause measurement error to use tape measure often to occur.Choose position at 5 the most in vertical direction and carry out the measurement of longitudinal size, measure efficiency comparison low, and be difficult to ensure that accuracy.
(2) for front draft lug (left) and rear draft lug (right) fore-and-aft distance (length direction) each other of heteropleural, and front draft lug (right) and the fore-and-aft distance of rear draft lug (left), owing to angle square and tape measure conjunction measuring must be used, therefore operational approach is difficult, additionally, due to welding deformation and the impact of draw beam web plane degree, often result in measurement inaccurate, closing is compared additionally, due to inner-cavity structure, use the method to measure operating difficulties, measuring error easily occurs.
After the draw beam composition products export that existing scheme produces, client is frequently found and qualified coupler and draft gear cannot be put into inner chamber or put into the problems such as rear interior cavity gap is the biggest, causes claim on account of quality.
Summary of the invention
The present invention mainly solves the measuring method operating difficulties existing for prior art, and measurement accuracy is difficult to ensure that, dimensional measurement efficiency is low, uses original measurement means, and disqualification rate is higher.Measure the low of efficiency, also result in the technical problem of the reduction of production efficiency；Provide one and can check whether draw beam inner chamber size meets requirement accurately, easily, thoroughly avoid in production and the out-of-size phenomenon of draw beam inner chamber occurs, it is ensured that draw beam composition can realize the detection device of a kind of size of inner cavity of railway vehicle and the detection method fitted together with coupler and draft gear.
The above-mentioned technical problem of the present invention is mainly addressed by following technical proposals:
