Abstract
A thread rolling device comprises a base, bearing seats, bearing sleeves, a main shaft, friction wheels, a vertical shaft and a friction rod. The number of the bearing seats is two. The two bearing seats are fixed on two ends of the base. A friction conic face is arranged on the outer circle of each friction wheel. The number of the friction wheels is two. The two friction wheels are in interference fit with the main shaft and are arranged on the main shaft in a reverse direction. The number of the bearing sleeves is two. The two bearing sleeves are in interference fit with the bearing seats and are arranged on the bearing seats. Two ends of the main shaft are supported in the bearing sleeves. The main shaft is capable of rotating and sliding freely. A friction touching face of the friction rod is a conic face. The friction rod is fixed on the small end of the vertical shaft. The vertical shaft is fixed on a facility rotary main shaft. A surface of the friction wheel forms a phosphatization layer through phosphatizing. The thread rolling device is capable of rolling under the condition of not changing the rotary direction of the facility main shaft when being installed in the facility and is good in rolling effect, low in processing cost, high in production efficiency, simple in structure, good in processing art, low in cost and good in rolling effect.
Description
Technical field
The utility model relates to a kind of silk rolling device, is specifically related to a kind of silk rolling device for the internal thread finishing.
Background technology
Along with welded nut application on welding product, the application product is more and more, screw thread is out of shape because of sweating heat and oil paint coating causes accuracy of thread not reach requirement, needs double thread to repair, thereby makes screw thread reach the assembly precision requirement.Traditional-handwork silk rolling efficient is low, labour intensity is large; And the machine silk rolling because ceaselessly forward, the counter-rotating of equipment motor moves in circles, causes motor burning easily.
Summary of the invention
It is a kind of simple in structure, easy to use that the purpose of this utility model is to provide, and is fit to be applied to the internal thread silk rolling, and processing cost is low, and production efficiency is high, and also be convenient to a kind of screw thread silk rolling device of installing.
For this reason, the technical scheme of the employing that the utility model adopts is: a kind of screw thread silk rolling device, comprise base, bearing block, bearing holder (housing, cover), main shaft, friction pulley, vertical shaft, friction-bar, bearing block is two, two bearing blocks are fixed on the base two ends, it is characterized in that: the cylindrical of friction pulley is provided with cone of friction, and described friction pulley is two, two friction pulleys are assemblied on the main shaft by the interference tight fit, and two friction pulleys are oppositely installed on main shaft; Bearing holder (housing, cover) is two, and bearing holder (housing, cover) is assemblied on the bearing block by the interference tight fit; The two end supports of main shaft is in bearing sleeve, and main shaft can rotate and slide freely; The frictional contact surface of friction-bar is the conical surface, and friction-bar is fixed on the small end of vertical shaft, and vertical shaft is fixed on the equipment rotary main shaft.
Above-mentioned friction pulley surface process to form phosphate coating by phosphatization, can play anticorrosionly, can increase friction effect again.
Beneficial effect: when the screw thread silk rolling, the utility model is installed on the equipment workbench, vertical shaft is fastened on the equipment rotary main shaft, take out the screw product that needs silk rolling, the machine tap with on the internal thread aligning screw thread silk rolling device main shaft of need silk rolling promotes screw thread silk rolling device main shaft gently, friction pulley relies on the friction-bar on the vertical shaft, friction-bar drives the friction pulley rotation under pressure, rotates thereby drive screw thread silk rolling device main shaft, makes the internal thread that machine tap rotates into needs silk rolling; Screw in the internal thread of need silk rolling fully when machine tap after, spur gently screw thread silk rolling device main shaft, another friction pulley relies on the friction-bar on the vertical shaft, friction-bar drives the friction pulley backward rotation under pressure, thereby drive screw thread silk rolling device main shaft backward rotation, make the machine tap rotation withdraw from the internal thread that needs silk rolling; Reach the purpose of quick silk rolling.The utility model is simple in structure, easy to use, be convenient to install, and in the situation that does not change the machine spindle rotation direction, realizes silk rolling, and silk rolling is effective, and processing cost is low, and production efficiency is high.
