Description
Technical field:
The invention belongs to coatings art, relate to coating tensile strength proving installation.
Background technology:
Along with the raising of coat preparing technology, increasing coating is applied in the middle of the commercial production.Tensile strength often is used to estimate the coating performance quality as an important indicator of coating material breakdown strength.
Yet for some coatings, especially some flimsy coatings (for example ceramic coat), from be prepared into the process between being installed on the testing machine, will inevitably can on coating, produce moment of torsion and moment of flexure, will produce certain damage for holding flimsy coating, before beginning test, destruction has just occured in the coating of test usefulness when serious; When coating prepared, the every startup of equipment once all needed to spend a large amount of man power and materials, in order to cut the waste, raised the efficiency, and need in the preparation coating, can disposable preparation as much as possible test test specimen.
Summary of the invention:
Technical matters to be solved by this invention is: the disassembly and assembly sample coupon will produce axial moment of torsion and moment of flexure in coating preparation and test set-up procedure, causes coating to produce damage; And preparation efficiency is lower, and can not guarantee the consistance of coating preparation.
The object of the invention is to overcome the shortcoming of above-mentioned prior art, a kind of coating tensile strength proving installation be provided,
Described coating tensile strength proving installation comprises abutment sleeve, backstay, setscrew nut, deposit subassembly, tommy and fastening bolt, stretching screw rod, universal joint;
Described deposit subassembly by geomery all identical the first butt joint body and the second butt joint body consist of;
Described the first butt joint body center is provided with the outside that loads hole, loading hole and is symmetrically arranged with a pair of pilot hole and a pair of fastener hole;
When coating prepares:
Described the first butt joint body and the second butt joint body decide by register pin and fastening bolt links together;
Described tommy passes the pilot hole of the first butt joint body and the second butt joint body;
Described fastening bolt passes the fastener hole of the first butt joint body and the second butt joint body;
Described some deposit subassemblies are through on the backstay by loading the hole;
Described some abutment sleeves are through on the backstay, and are spaced between some deposit subassemblies;
The described backstay two ends of having run through many groups deposit subassembly are fixed by setscrew nut, and make close contact between each deposit subassembly and abutment sleeve;
During the test of coating tensile strength:
Described the first butt joint body and the second butt joint body link together surely by register pin;
The threaded end of described stretching screw rod is threaded connection on the loading hole of deposit subassembly;
The threadless end of described stretching screw rod and universal joint link together.
Described the first butt joint body and the second butt joint body are right cylinders.
The using method of described coating tensile strength proving installation is docking together butt joint body first, and tommy is inserted respectively on the pilot hole with matching, and test specimen is positioned, the axial moment of torsion of butt joint body that produces in cargo handling process after preventing; Again fastening bolt is assemblied in above the fastener hole, butt joint body is tightened together, prevent from cargo handling process, producing moment of flexure and then coating being produced destruction at butt joint body; Then once will organize the deposit subassembly that fits together extends through above the backstay by the loading hole on it more, the centre separates with abutment sleeve, and at backstay two ends will organize deposit subassembly and abutment sleeve with clamp nut more and clamp, prevent from many deposit subassembly being slided at backstay, on Preparation equipment, can once finish the preparations of many group sample coatings; After the coating preparation finishes, deposit subassembly is disassembled one by one; And the stretching screw rod is assemblied in it on the loading hole at corresponding butt joint body center; The butt joint body that has assembled the stretching screw rod is installed to Universal joint connector, afterwards the fastening bolt on the butt joint body is laid down, because tommy is to be slidingly matched, so tommy can be retained in above the testpieces, then carries out coating tensile strength testing experiment.
The present invention has following beneficial effect: butt joint body does not use boss location, has simplified difficulty of processing, adds can be very easily the smooth finish of contact interface to be remained on a higher level man-hour.During preparation, by with the loading hole at deposit subassembly center through on the backstay, with some abutment sleeves each deposit subassembly is spaced at backstay, and with setscrew nut stationary positioned bar two ends, so that more close contact between each deposit subassembly and abutment sleeve can disposablely will be organized deposit subassembly and navigate on the backstay, the simultaneously preparation test specimens of organizing more, guarantee the consistance of coating preparation, improved the efficient of test material preparation.During assembling, by tommy is installed on the pilot hole, the one the second butt joint bodies can be positioned, and can prevent from being subject at preparation and test set-up procedure floating coat the destruction of moment of torsion.Fastening bolt is installed on the fastener hole of the one the second butt joint bodies, can prevents that coating is subject to the damage of moment of flexure in the process that the deposit subassembly dismounting is loaded, improved the efficient of success of the test.
