Description
Technical Field
The utility model relates to a can realize the test of suppressing of finished product hydraulic nut, solve the finished product and suppress the hydraulic nut who has a technical problem and suppress the device.
Background
In the production of large-scale pull rods and common nuts, the common nuts cannot meet the requirements due to continuous progress of production technology and equipment, and a novel hydraulic nut needs to be manufactured and subjected to a pressure test. In prior art will make the finished product hydraulic nut assemble and suppress on the finished product pull rod of processing, moreover suppress at every turn and need assemble two hydraulic nut and mutually support and just can accomplish and suppress the experiment, the result not only causes pull rod screw thread damage and partial nut screw thread to scrap and need make again because of suppressing in the test process, so need design one kind to suppress the device and avoid pressing because of the assembly and cause the damage or the damage of pull rod and nut screw thread, can effectively shorten simultaneously and suppress the time and improve work efficiency.
Disclosure of Invention
An object of the utility model is to solve exist among the prior art problem not enough and provide one kind and avoid the damage of pull rod and nut screw or the condition of scrapping to take place, the effectual hydraulic nut who improves the efficiency of suppressing suppresses the device.
The technical scheme of the utility model is realized like this: a hydraulic nut pressing device comprises an upper pressing plate and a lower pressing plate, wherein the upper pressing plate is placed above a hydraulic nut, the lower pressing plate is placed below the hydraulic nut, a groove is formed in the bottom surface of the lower pressing plate, a lower pressing cap with a threaded inner hole is placed in the groove of the lower pressing plate, an upper pressing cap with a threaded inner hole is arranged on the upper pressing plate, a tensioning bolt penetrates through the upper pressing plate, the upper pressing cap, the hydraulic nut, the lower pressing plate and the lower pressing cap, the upper pressing plate, the hydraulic nut and the lower pressing plate are fixedly locked through the tensioning bolt, the upper pressing plate, the hydraulic nut and the lower pressing cap, an annular cavity inlet of the hydraulic nut is communicated with one end of a high-pressure hose through a hydraulic nut adapter, the other end of the high-pressure hose is communicated with a hand pump through a hand pump adapter, and a.
The tension bolt and the upper pressure cap and the lower pressure cap are connected and fastened by adopting trapezoidal threads.
The technical scheme of the utility model the positive effect that produces as follows: the utility model provides a hydraulic nut suppression device, is including setting up two clamp plates in hydraulic nut upper and lower both sides respectively, passes hydraulic nut and upper and lower clamp plate with tie bolt during the use and presses the cap to lock whole set suppression device fixedly through two at upper and lower both ends, tie bolt and pressure adopt trapezoidal threaded connection between the cap because trapezoidal thread has better wearability and to the neutrality better than other screw threads, the clearance is adjustable, and processing property is good, and life is longer. Consequently the utility model provides an unnecessary damage or damage that this kind of product caused because of suppressing, accomplish hydraulic nut's the test of suppressing, test process safe and reliable, the efficiency of software testing is high.
