Description
Technical Field
The invention relates to the technical field of equipment inspection, in particular to a combined inspection device and an inspection method for a crank arm type stirring arm.
Background
The mixing arm is an important wear-resistant part which is arranged on the concrete mixer, is loaded with mixing blades and performs the mixing action. The stirring arm generally comprises an arm seat and an arm rod; the arm seat is generally provided with an arm shaft mounting surface and an arm seat mounting hole, and the stirring arm is matched with a stirring shaft of the stirrer through the arm shaft mounting surface and is connected with the stirring arm seat through the arm seat mounting hole; the upper end of the arm rod is generally provided with a blade mounting rod, and the width of the blade mounting rod is slightly smaller than the distance between the limiting ribs of the stirring blades; the blade mounting rod is generally provided with two blade mounting holes with waist-shaped through holes, and the stirring blade is connected with the stirring arm through the blade mounting rod and the blade mounting holes of the stirring arm to perform a stirring function.
Stirring arms are of many kinds, most of which, from the type of arm, are straight arms, i.e. the arm is straight, perpendicular to the horizontal or slightly inclined. A bent arm type stirring arm has appeared in recent years, namely the arm rod belongs to a bent type, and the bent arm type stirring arm is not easy to break because of higher strength, has certain delay with stirring blades when stirring materials, greatly prolongs the service life, and has the advantages of being popularized in a certain range.
However, the bell crank type stirring arm also presents a difficulty to the foundry manufacturer in terms of how to inspect, particularly, the blade mounting rod and the blade mounting hole. For the test of straight type stirring arm, use ruler, slide caliper, height gauge, just can accomplish with conventional test method, but for crank arm type stirring arm, because the plane on its blade installation pole belongs to the space plane, the line arrangement of blade mounting hole on the plane of blade installation pole belongs to the space straight line, and conventional test method can not be competent at.
The crank arm type stirring arm is easy to deform in the casting and heat treatment process due to the large difference of the arm thickness of each part, the deformation amount of each part is different, products cannot be selected and inspected, and the whole inspection must be carried out.
Some foundries place the crank arm type stirring arm on a machining marking platform and adopt a metalworking marking method for inspection. However, this method has the following disadvantages: (1) the inspection consumes much time and is only suitable for sampling inspection; (2) the isolated dimension can be checked, but the spatial plane on the blade mounting rod and the spatial straight line of the blade mounting hole on the blade mounting rod, with respect to the spatial dimensions of the arm shaft mounting surface and the arm base mounting hole, cannot be correctly checked.
Some foundries manufacture simulation devices according to the sizes of a stirring barrel and a stirring shaft of the stirrer, and test the simulation devices by a simulation installation method. However, this method has the following disadvantages: (1) the inspection can be carried out only by mounting the crank arm type stirring arm, the stirring arm seat and the stirring blade, and the repeated mounting and dismounting are needed, so that the time consumption is high, the inspection process is complicated, and the inspection is only suitable for sampling inspection; (2) the simulation device often has a lot of differences with the actual installation of equipment manufacturers, and also can generate false detection.
Because the missing rate and the wrong rate of detection of the crank arm type stirring arm are high, equipment manufacturers are cautious when designing and adopting the crank arm type stirring arm, the popularization and the application of the crank arm type stirring arm are directly limited, sometimes, even when parts such as an end lining plate, an arc lining plate, an arm seat, a stirring arm seat and the like are installed, problems are discovered in the later installation period of installing the stirring blade, and huge troubles are caused for casting manufacturers and equipment manufacturers.
Through retrieval, the Chinese patent application number: 201320847980X, entitled: stirring arm inspection machine, this application case includes the base, and fixed mounting has the support post on the right-hand member face of base, and the upper end fixed mounting of support post has the detection mesa, is equipped with the pick-up plate on detecting the mesa, and the pick-up plate passes through locating pin fixed mounting on detecting the mesa, and the left end face of base is equipped with the limiting plate. This application can only be applied to the most basic stirring arm, and there is no reference to the above-mentioned crank arm type stirring arm.
