Abstract
The utility model relates to a two-point type clamping device for a high-power thyristor, which comprises a spring press plate, a limit indicator, a bolt positioning top plate, bolts and a bolt positioning bottom plate. The bolt limiting top plate and the spring press plate are connected with each other by the bolts so as to form a frame structure, the spring press plate is positioned below the bolt positioning top plate and is an arc-shaped structure, and the limit indicator is arranged in the middle of the bolt positioning top plate. An arc-shaped support plate is disposed between the spring press plate and the bolt positioning top plate, is connected onto the bolts and spherically contacts with two ends of the spring press plate. Compared with the prior art, the two-point type clamping device for the high-power thyristor has the advantages that the limit indicator can clearly display a target pressure position when the thyristor is pressed, stress is transmitted uniformly by the aid of the arc-shaped support plate, and the two-point type clamping device is fine in fastening effect, long in service life and convenient in operation.
Description
Technical field
The utility model relates to a kind of fastener of high-power thyristor.
Background technology
In the prior art, the thyristor employing is gone up lower platen and is directly used the bolt crimping, this kind compressing structure causes nut to be subjected to being partial to the influence of moment, when thyristor requires force value very big, screw rod can occur bending and deformation even rupture, nut and screw flight also can suffer destruction in various degree simultaneously, can't meet the demands.Whether and the thyristor hold down gag do not have spacing indicating device, can not directly indicate the spring bearer plate position and meet the demands when compressing thyristor.
Summary of the invention
The purpose of this utility model provides a kind of two point form clamping device that is used for high-power thyristor, and this device is provided with spacing indicating device, can clear and definite display-object pressure position when compressing thyristor; Setting by the arc supporting bracket can make stressed transmission even, and is fastening effective, and long service life is easy to operate.
For achieving the above object, the utility model is achieved through the following technical solutions:
The two point form clamping device that is used for high-power thyristor, comprise spring bearer plate, spacing indicating device, bolt location top board, bolt, bolt positioning plate, bolt location top board, spring bearer plate are connected by bolt with the bolt positioning plate, constitute frame structure, spring bearer plate is positioned at the bottom of bolt location top board, is arcuate structure; Be provided with spacing indicating device at top board middle part, bolt location.
Be provided with the arc supporting bracket between described spring bearer plate and the bolt location top board, the arc supporting bracket is connected on the bolt, constitutes sphere with the two ends of spring bearer plate and contacts.
Compared with prior art, the beneficial effects of the utility model are:
1) this device is provided with spacing indicating device, when compressing thyristor, work as in the fastening nut process, when the arcuate structure spring bearer plate becomes straight gradually, when its middle part touches spacing indicating device, represent that promptly force value has reached desired value, this device can display-object pressure position more directly perceived, has improved operating efficiency, and the mode that can adopt hydraulic press or manual operation to combine clamps thyristor.
2) setting by the arc supporting bracket can make stressed transmission even, and is fastening effective, and long service life is easy to operate.Adopt the sphere mode of transfer force, stress point can be exerted all one's strength stepless action on stress surface changing in fastening process.
3) this structure can arbitrarily manually be changed the thyristor of optional position owing to adopted pressure spot position and arc transition structure, and thyristor is changed easy for installation.
