Description
Technical field
The utility model relates to a kind of device of mechanical hook-up inner cavity size, especially relate to a kind of rolling stock inner cavity size pick-up unit and.
Background technology
Rolling stock all needs to install coupler and draft gear, the longitudinal force and the impulsive force that for alleviating train, at operational process, produce.Coupler and draft gear is arranged in the inner chamber that the draw beam of rolling stock forms, and the size of this inner chamber is regarded as critical size, directly affects final success coupler and draft gear is installed.Inner chamber consists of front draft lug (left side), front draft lug (right side), rear draft lug (left side), rear draft lug (right side), draw beam web (left side), draw beam web (right side), draw beam upper cover plate, draw beam lower cover assembly welding.For example we export the vitals draw beam composition of the railway freight-car of the U.S., need to guarantee that the longitudinal size of all positions of inner chamber is
not only need to guarantee that draw beam forms the front draft lug (left side) of homonymy and the distance between rear draft lug (left side) is
and the distance between front draft lug (right side) and rear draft lug (right side) is
and front draft lug (left side) and rear draft lug (right side) fore-and-aft distance (length direction) each other that need to guarantee draw beam composition heteropleural are
and front draft lug (right side) and rear draft lug (left side) fore-and-aft distance (length direction) are each other
as Fig. 1 draw beam forms as shown in inner chamber schematic diagram.
Because the draw beam composition of outlet need to be assembled coupler and draft gear abroad, therefore must guarantee draw beam inner cavity size, guarantee client installs coupler and draft gear smoothly like this.
Existing technical scheme adopts tape measure and angle square to measure inner cavity size.
First adopt tape measure draw beam to form the fore-and-aft distance between the same side front draft lug and rear draft lug
in assembly welding process, there is assembling deviation and welding deformation, and there is mismachining tolerance in front draft lug and rear draft lug accessory, therefore may cause, be arranged on the front draft lug of homonymy on draw beam web and the distance between rear draft lug, the size of diverse location is different in vertical direction.We must adopt tape measure to choose in vertical direction the fore-and-aft distance between 5 place's position measurement front draft lugs (left side) and rear draft lug (left side), and the fore-and-aft distance between front draft lug (right side) and rear draft lug (right side), to guarantee that between homonymy front draft lug and rear draft lug, any position meets
dimensional requirement.
The front draft lug (left side) and rear draft lug (right side) fore-and-aft distance (length direction) each other that for draw beam, form heteropleural in inner chamber, and front draft lug (right side) and rear draft lug (left side) fore-and-aft distance each other
cannot directly measure by tape measure, must adopt two L300X300 angle squares and tape measure conjunction measuring.For example, while measuring fore-and-aft distance (length direction) each other of front draft lug (left side) and rear draft lug (right side), one side of one of them angle square is placed on draw beam web (left side), another side alignment front draft lug (left side) side, another one angle square is placed on the draw beam web on opposite, another side alignment rear draft lug (right side) side, then using the distance between tape measure two angle squares, is exactly needed distance.Due to the impact of welding deformation and draw beam web plane degree, often cause measurement inaccurate.This measuring method needs two people to coordinate just and can complete in addition, and one of them people operates an angle square, and another person operates other one angle square.
Yet there are problems in prior art:
(1) for the front draft lug (left side) of homonymy and the fore-and-aft distance between rear draft lug (left side), and the fore-and-aft distance between front draft lug (right side) and rear draft lug (right side) is measured, during due to actual measurement, this inner chamber three side sealing closes, and adopts tape measure often to occur that measurement difficulty, tape measure tilt to cause measuring error.Choose in vertical direction in addition 5 positions, place and carry out the measurement of longitudinal size, measure efficiency lower, and be difficult to guarantee accuracy.
(2) for front draft lug (left side) and rear draft lug (right side) fore-and-aft distance (length direction) each other of heteropleural, and the fore-and-aft distance of front draft lug (right side) and rear draft lug (left side), owing to must adopting angle square and tape measure conjunction measuring, therefore method of operating is difficult, due to the impact of welding deformation and draw beam web plane degree, often cause measurement inaccurate, in addition because inner-cavity structure relatively seals in addition, adopt the method to measure operating difficulties, easily occur measuring error.
The draw beam that existing scheme is produced forms after products export, and the frequent discovery of client cannot be put into inner chamber by qualified coupler and draft gear or be put into the problems such as rear interior cavity gap is too large, causes claim on account of quality.
Utility model content
The utility model is mainly to solve the existing measuring method operating difficulties of prior art, and measurement accuracy is difficult to assurance, and dimensional measurement efficiency is low, adopts original measurement means, and disqualification rate is higher.Measure the low of efficiency, also caused the technical matters of the reduction of production efficiency; Provide a kind of and can check accurately, easily whether draw beam inner cavity size meets the demands, in thoroughly having avoided producing, there is the underproof phenomenon of draw beam inner cavity size, guarantee that draw beam forms pick-up unit and the detection method that can realize a kind of rolling stock inner cavity size fitting together with coupler and draft gear.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
A pick-up unit for rolling stock inner cavity size, is characterized in that, comprises by web, two end casings and two casings that cover plate forms; Described casing both sides are fixed with respectively at least one turning rolls.
At the pick-up unit of above-mentioned a kind of rolling stock inner cavity size, described turning rolls comprises rolling bearing, bearing mounting base, main shaft and set bolt; Described main shaft two ends are provided with rolling bearing, and main shaft is fixed on bearing mounting base, and described bearing mounting base is fixed on end casing by set bolt.
Pick-up unit at above-mentioned a kind of rolling stock inner cavity size, described turning rolls is four, on two end casings, be fixed with respectively two, turning rolls on each end casing be arranged in parallel, and defining vertical range between the rolling bearing edge of an end casing upper roller frame and the rolling bearing edge of another end casing upper roller frame is H, tested rolling stock inner cavity size is M, and the scope of H is to be less than M.
At the pick-up unit of above-mentioned a kind of rolling stock inner cavity size, described two end casings top is also fixed with two handheld rings, and described handheld ring and turning rolls be arranged in parallel; Upper cover plate in described two cover plates is also parallel is fixed with two for reinforcing the L shaped connection iron of upper cover plate and web, and described L shaped connection Tie Tong crosses set bolt and fixes.
Therefore, the utlity model has following advantage: 1, this inner chamber detection method is simple, only pick-up unit need be put into draw beam and form inner chamber, just can judge that whether inner chamber is qualified, detection efficiency is high; 2, this inner chamber structure of the detecting device is simple, makes simply, and cost is low; 3, adopt this inner chamber detection method and device thereof can guarantee that inner cavity size is all qualified.
