Abstract
The invention relates to a tool for testing bobbin coil binding power and a method therefor. The tool comprises a guide rail base (1), a first suspended rod (2), a first lock screw (3), a load (4), a bobbin coil (5), a central spindle (6), a second lock screw (7) and a second suspended rod (8). At the tangential direction of the outmost coil layer of the bobbin coil (5), the load (4) is hung on a self-adhesive varnished wire at an end of the bobbin coil (5), the weight of the load (4) is increased gradually until the self-adhesive varnished wire on which the load (4) is hung is separated from the bobbin coil (5), and then the weight of the load (4) is a binding power value of the outmost coil layer of the bobbin coil (5). Through results of coil binding power testing, heating temperature and heating time in heat bonding process parameters can be adjusted, and therefore binding power values of bobbin coils can be quantified and controlled.

Therefore in the urgent need to designing a kind of shaped framework coil cohesive force test fixture and method.
Summary of the invention
The purpose of the present invention is to propose to a kind of shaped framework coil cohesive force test fixture and method.
The technical scheme is that
A kind of shaped framework coil cohesive force test fixture, is made up of guiderail base the 1, first cantilever lever the 2, first lock-screw 3, load 4, shaped framework coil 5, mandrel the 6, second lock-screw 7 and the second cantilever lever 8; Guiderail base 1 is the base plate with guide-track groove; First cantilever lever 2 and the second cantilever lever 8 are placed in parallel in the guide-track groove of guiderail base 1, and may move the spacing of adjustment, one end of first cantilever lever 2 and the second cantilever lever 8 is equipped with the installing hole that can place mandrel 6, and on installing hole, it is respectively equipped with the first lock-screw 3 and the second lock-screw 7 of fixed central spindle 6, mandrel 6 is that two ends match with the installing hole of the first cantilever lever 3 and the second cantilever lever 8 respectively, the middle axle matched with shaped framework coil 5 endoporus, mandrel 6 can flexible rotating between shaped framework coil 5 endoporus.
A kind of shaped framework coil cohesive force method of testing, its operating procedure is as follows:
Step 1: self-binding enamel wire is wound on skeleton and forms shaped framework coil 5 to be tested through heat bonding, gets out shaped framework coil cohesive force test fixture as above;
Step 2: be enclosed within mandrel 6 by shaped framework coil 5, first puts in the installing hole of the first cantilever lever 3 and screws the first lock-screw 3, and then mobile second cantilever lever 8 that adjusts makes mandrel 6 penetrate in its installing hole and screws the second lock-screw 7;
Step 3: in the tangential direction of the outermost layer coil of shaped framework coil 5, load 4 is hung on the self-binding enamel wire of shaped framework coil 5 termination, it is stepped up the weight of load 4, until the self-binding enamel wire of hanging load 4 is just peeled off with shaped framework coil 5, now the weight of load 4 is the bonding force value of shaped framework coil 5 outermost layer coil.
The present invention has the advantage that and beneficial effect: self-binding enamel wire is wound on skeleton and puts the enterprising line circle cohesive force test of test fixture in the present invention through the shaped framework coil of heat bonding, heating-up temperature in thermal bonding technology parameter and heat time heating time can be adjusted by coil cohesive force test result, so that shaped framework coil cohesive force value is quantified and controls. I is had tens kinds of type products and is used the coil cohesive force test fixture in the present invention and method at present, shaped framework coil cohesive force value is not only made to obtain effective control, and the adjustment of shaped framework coil performance to its insulating properties without any harmful effect, thus ensure that product quality, it was demonstrated that respond well.
