Technical field
The utility model relates to a kind of object stiffness testing device, particularly a kind of device of spring high temperature stiffness testing.
Background technology
According to the knowledge of the applicant: China does not have the external diameter of mensuration at present and is φ 9-φ 10.5mm, highly is the spring rate determinator of 28-32mm, and the device of particularly measuring spring high temperature rigidity still belongs to blank, so can't satisfy the needs that this class spring rate detects.
Summary of the invention
The utility model purpose is exactly in order to satisfy the needs of said determination spring high temperature rigidity, according to the test philosophy of general spring rate, provides a kind of spring high temperature stiffness testing device.
The utility model purpose is to realize with such technical measures: a kind of spring high temperature stiffness testing device, comprise worktable, electric furnace, guide pole, gland and measuring disk, counterweight, clock gauge, support, on horizontal table, be provided be used to provide check temperature required add electrothermal stove, be provided with in this electric furnace and pass electric furnace guide pole vertical with worktable and that be connected with support; On guide pole, put tested spring, gland and measuring disk in regular turn, place counterweight on this measuring disk, thereby make the common gravity (load) of counterweight, measuring disk and gland satisfy the required power of spring tester; Have the clock gauge that is used for deformation displacement amount on the detection springs short transverse in measuring disk, add electrothermal stove and link to each other with the temperature control instrument of band temperature sensor.
Described guide pole flexibly connects by cross bar on the support and worktable.
Has the gap between described guide pole and the tested spring.
Has the gap between described measuring disk, gland and the guide pole.
Described temperature sensor is a thermopair.
This verifying attachment that adopts abovementioned technology to make, reading and institute's application of load according to clock gauge can calculate tested spring rate.
The beneficial effects of the utility model: this device especially satisfies the needs of turbine steam seal with the high temperature alloy spring production testing, can test 400～700 ℃ of the spiral compression spring of external diameter φ 5～φ 20mm and Range of measuring temp; The high temperature rigidity of the hundreds of of tens a heat (batch) numbers spring after measured, the data reappearance of its measuring spring rigidity is fine, illustrates that thus this device is reasonable in design, measures accurately.It is a domestic initiation, adds the blank of having filled out this technical field of China.

Embodiment
Referring to Fig. 1, this verifying attachment comprises: worktable 1, electric furnace 4, guide pole 9, gland 5, measuring disk 7, counterweight 8, clock gauge 6, support 10.Support 10 is vertically fixed on the worktable 1, guide pole 9 passes the roof and 1 vertical linking to each other of worktable of the electric furnace 4 of heating, (there is an aperture cross bar 11 terminations at support 10 by support 10 supports in the upper end of guide pole 9, the upper end of guide pole 9 is passed this hole and is fixed with screw, described hole and guide pole 9 have certain interval, guide pole 9 can be moved up and down), make it to keep stable, lower end that step 2 is arranged, tested spring 3, gland 5, measuring disk 7 are inserted in guide pole 9 in regular turn and are placed on the step 2; Place two counterweights 8, two clock gauges 6 of following installation above the measuring disk 7, clock gauge 6 is by being connected with worktable 1 with support 13 hinge connection; Gapped between measuring disk 7, gland 5, spring 3 and the guide pole 9, the roof of gland 5 and electric furnace 4 is worn between the cinclides also gapped.About the internal diameter little 1mm of the diameter of guide pole 9, to guarantee the free dilatation of spring energy than tested spring 3; The internal diameter of gland 5 than the about 1mm of the diameter of guide pole 9 about so that gland 5 can move up and down at guide pole 9.Electric furnace 4 links to each other with the temperature control instrument 12 of band thermopair, and electric furnace 4 is by its heating-up temperatures of temperature control instrument 12 control of band thermopair (less demanding as if measuring accuracy, sensor can be with infrared ray sensor etc.).
The operation steps of the utility model check spring rate is as follows:
1, checks that can gland 5 and measuring disk 7 the easy on and off activity; Can whether clock gauge 6 installs, free movable;
2, tested spring 3 is put into the measuring position, add the load that is lower than preloading, check that can tested spring 3 Free Transform;
3, with electric furnace 4 heating, be warmed up to check temperature (400～700 ℃), be incubated about 10 minutes;
4, by the regulation of tested spring 3 detail of designs, add preloading, after tested spring 3 distortion are stable, reading (reading A) on the record clock gauge 6, increase counterweight 8 load is added to test load, after camber of spring is stable, the reading (reading B) on the record clock gauge 6.In checkout procedure, the temperature of electric furnace 4 remains on test temperature;
5, calculate the high temperature stiffness K of tested spring 3:
Spring rate K=(test load-preloading) ÷ (reading B-reading A)
