Description

Technical Field

[0001] The present invention relates to the technical field of bobbin seat strength detection, and in particular to a bobbin seat strength detection device and method. Background Art

[0002] Since the spool seat needs to withstand a large launch thrust during operation, it is necessary to simulate the standard launch thrust that the spool seat is subjected to during operation to perform strength testing before leaving the factory to prevent unqualified spool seats from being delivered to the customer. After being subjected to the launch thrust, the root of the annular positioning boss inside the spool seat, which is used to connect the chassis and the spool together, will be deformed or even torn. Currently, the strength testing of the spool seat is carried out by plugging and injecting high-pressure water. Obviously, this not only requires the spool seat to be rust-proofed and air-dried before and after the test, resulting in cumbersome testing operations, low testing efficiency, and high testing costs, but also prone to plugging failure during the test, resulting in inaccurate test results or even failure. Summary of the Invention

[0003] In view of the deficiencies in the background technology, the present invention provides a spool seat strength detection device and method to solve the problem of how to conveniently and accurately detect the strength of the spool seat.

[0004] In order to solve the above technical problems, the present invention provides a spool seat strength detection device, comprising an electronic universal testing machine, a pressure shaft and a fastening ring seat for clamping the spool seat to be tested, the fastening ring seat being detachably fastened to the workbench of the electronic universal testing machine and being located directly below the pressure head of the electronic universal testing machine, the height of the pressure shaft being greater than the height of the spool seat to be tested, and a threaded ring block is provided on the circumferential wall of one end thereof, which is adapted to the annular positioning boss of the spool seat to be tested. When in a testing state, the spool seat to be tested is clamped in the fastening ring seat, one end of the pressure shaft is threadedly connected to the spool seat to be tested through the threaded ring block, and the other end extends out of the spool seat to be tested and is pressed by the pressure head of the electronic universal testing machine.

[0005] In one embodiment of the present invention, a handle is vertically provided on the peripheral wall of the pressing shaft away from the threaded ring block.

[0007] In one embodiment of the present invention, the pressing shaft and the threaded ring block are integrally formed.

[0008] In one embodiment of the present invention, the inner circumferential wall of the fastening ring seat and the outer circumferential wall of the threaded ring block are both coated with a lubricating and wear-resistant layer.

[0009] In one embodiment of the present invention, a shock-absorbing pad is provided at the bottom of the fastening ring seat.

[0010] The present invention also provides a spool seat strength detection method, which is performed in the above-mentioned spool seat strength detection device and includes the following steps:

[0011] Step S1, fastening the fastening ring seat to the workbench of the electronic universal testing machine, with the upper side facing the pressure head of the electronic universal testing machine;
