Abstract
The utility model provides a device preventing rollers of a high-speed cutting machine from being loosened. The high-speed cutting machine comprises a straightening machine, roller devices and a cutting die, wherein each roller device comprises a screw, a gasket, a roller, a bearing and a gear, and the screw, the gasket, the roller, the bearing and the gear are sequentially installed on a roller shaft. The device preventing the rollers from being loosened is characterized in that roller key grooves are arranged in roller holes in the four rollers, and the four roller shafts corresponding to the roller key grooves are respectively provided with a roller shaft round hole. Two ends of each of four locating pins are respectively arranged in the corresponding roller shaft round hole and in the corresponding roller key groove, one end of each locating pin is a cylinder, and the other end of each locating pin is a square column. Each cylinder at one end of each locating pin is tightly installed in each roller shaft round hole in each roller shaft in a matched mode. The square column at the other end of each locating pin is tightly installed in each roller key groove in each roller hole in the matched mode. The rollers and the roller shafts are fixed and located through the locating pins so that the rollers and the roller shafts can always rotate synchronously. Therefore, errors are not generated on the four rollers when pin shaft roller materials are fed, and short pins with insufficient lengths are not generated when the high-speed cutting machine cuts.
Description
Technical field
The utility model relates to a kind of loosing-proof device, and particularly a kind of high speed is cut the anti-wheel loosening device that rolls of pin machine.
Background technology
Our company is roller chain professional production producer.The roller chain bearing pin that uses many " Cixi City has been slapped town national defence mould hardware factory " to produce in roller chain bearing pin production process is cut at a high speed the pin machine.These roller chain bearing pins are cut at a high speed the pin machine and are cut off that the speed of bearing pin is very fast, work efficiency is very high.Per minute cuts off bearing pin 300-400 root.It has advantages of that also the pin of cutting end face is smooth, lossless, easy-maintaining.In the production process of cutting the pin machine, first with the straightening of circle shape bearing pin roller material, two pairs four are rolled wheel and the bearing pin roller material after the straightening is compressed deliver to the cutting machine place and be cut into bearing pin.But this bearing pin is cut at a high speed four of pin machine and is rolled wheel and all be fastened on by pad and nut spinning and roll on the wheel shaft.Four wheels that roll that rolling on the wheel shaft also usually reverse except normal forward in roller chain bearing pin production process.Roll the wheel rotating often and rolled rolling wheel and will become flexible on the wheel shaft by fastening nuts.Rolling rolling in the loosening situation of wheel on the wheel shaft, causing rolling wheel and can not follow fully and roll wheel shaft and rotate synchronously, when sending bearing pin roller material, easily producing error, thereby produce the inadequate short pin of length.
Summary of the invention
The purpose of this utility model provides the anti-wheel loosening device that rolls that a kind of high speed is cut the pin machine.Should anti-roll the wheel loosening device can make and roll wheel and roll wheel shaft and be fixed the location by alignment pin.Can will roll wheel be fixed on tightly and roll on the wheel shaft and can not become flexible, make and roll wheel and roll wheel shaft and rotate synchronously all the time.Such four are rolled wheel just can not produce error when sending bearing pin roller material, just can not produce the inadequate short pin of length when cutting the pin machine at a high speed and cutting pin.
The technical solution of the utility model is: a kind of high speed is cut the anti-wheel loosening device that rolls of pin machine.Cutting the pin machine at a high speed includes straightener, rolls wheel apparatus and cutting dies.Four are rolled wheel apparatus and include and be contained in successively the screw, the pad that roll on the wheel shaft, roll wheel, bearing and gear.Be characterized in: the anti-wheel loosening device that rolls is to roll rolling of wheel at four all to open one on the wheel hole and roll wheel key way.With respectively roll corresponding four of wheel key way and roll and all open one on the wheel shaft and roll the wheel shaft circular hole.Four ends are that the cylinder other end is that the two ends of the alignment pin of square body are respectively charged into four and corresponding roll wheel shaft circular hole and four corresponding rolling in the wheel key way.The cylinder of alignment pin one end is installed with the wheel shaft circular hole tight fit of rolling of rolling on the wheel shaft.The square body of the alignment pin other end is installed with the wheel key way tight fit of rolling of rolling on the wheel hole.
Screw off screw and take down pad and roll wheel from rolling wheel shaft first during assembling.The cylinder of alignment pin inserted roll in the wheel shaft circular hole, will roll and roll wheel key way on the wheel and aim at and to roll wheel behind the square body of alignment pin and install to and roll on the wheel shaft.Load onto pad and screwing screw rolling wheel shaft again.Alignment pin of the present utility model will roll wheel and roll wheel shaft and be fixed together tightly and add screw and will roll wheel and be tightened on and roll on the wheel shaft.Roll like this wheel roll on the wheel shaft just can not produce loosening.
The utility model has the advantages that provides a kind of high speed to cut the anti-wheel loosening device that rolls of pin machine.Should anti-roll the wheel loosening device can make and roll wheel and roll wheel shaft and be fixed the location by alignment pin.Can will roll wheel be fixed on tightly and roll on the wheel shaft and can not become flexible, make and roll wheel and roll wheel shaft and rotate synchronously all the time.Such four are rolled wheel just can not produce error when sending bearing pin roller material, just can not produce the inadequate short pin of length when cutting the pin machine at a high speed and cutting pin.
