Abstract
The utility model relates to a novel internal grinding machine of a heavy caliber seamless steel pipe, belonging to the technical field of machining devices. The front end of a transmission shaft is fixedly connected with a grinding wheel; the transmission shaft is supported in a shaft sleeve by a bearing; the rear end of the transmission shaft is connected at the output end of a hydraulic motor which is arranged in a motor cover; the motor cover is fixedly connected with the shaft sleeve; the rear end of the motor cover is fixedly connected with a lengthened grinding rod; and the rear end of the lengthened grinding rod is connected with a grinding pressure adjusting oil cylinder. An intermediate support bearing is omitted in the internal grinding machine, so that the rigidity of the transmission shaft is improved; the lower pressure of the grinding wheel, which is adjusted by a screw rod at the rear end of the original grinding rod, is adjusted by the existing push action cylinder; and the grinding pressure adjusting oil cylinder is installed at the tail of the lengthened grinding rod, so that the grinding pressure of the grinding wheel can be adjusted according to operation need, and ground finish can be carried out on the deep part of a longer steel pipe, therefore, the stability of equipment is improved, the grinding pressure of a grinding wheel part is increased, the service life of the equipment can be prolonged, and the working efficiency of the equipment is improved.
Description
Technical field
The utility model relates to a kind of novel heavy caliber seamless steel pipe internal grinder, belongs to the technical field of machining equipment.
Background technology
Traditional seamless steel pipe internal grinder adopts rearmounted driven by motor major axis to drive emery wheel, to realize the purpose to the seamless steel pipe grinding.Adopt screw mandrel to adjust the emery wheel downforce in the rear end,, increase the emery wheel downforce, cause the power transmission shaft bending, cause imbalance, make the power transmission shaft vibrations bigger, be easy to cause power transmission shaft intermediate supports bearing and motor to damage for increasing work efficiency.
Summary of the invention
The purpose of this utility model is to provide the heavy caliber seamless steel pipe internal grinder that a kind of balance is good, vibrations are little, durable.
The utility model comprises power transmission shaft, the front end of described power transmission shaft is fixedlyed connected with emery wheel, described power transmission shaft by bearings in axle sleeve, the rear end of described power transmission shaft is connected the output of a hydraulic motor, described hydraulic motor is arranged in the motor cover, described motor cover is fixedlyed connected with described axle sleeve, and a fixedly connected lengthening mill bar connects grinding pressure in the rear end of described lengthening mill bar and adjusts oil cylinder in the rear end of described motor cover.
Utility model has reduced the intermediate supports bearing, the rigidity of the power transmission shaft of increase by the rearmounted motor-driven of long pass moving axis being changed into the fluid motor-driven of existing short pass moving axis; Former mill rod rear end is adjusted the emery wheel downforce with screw mandrel and is changed existing push action cylinder adjustment downforce into, grinding pressure is adjusted oil cylinder and is installed in lengthening mill bar afterbody, can adjust the grinding pressure of emery wheel according to the operation needs, can carry out grinding to the deep of longer steel pipe, improved the stability of equipment, strengthen the grinding pressure at emery wheel position, improved the life-span and the operating efficiency of equipment.
In order further to improve the stability in the use, the end face of described emery wheel is provided with the driving flange, and described driving flange is fixedlyed connected with described power transmission shaft.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Among the figure, 1 grinding pressure is adjusted oil cylinder, 2 lengthening mill bars, and 3 hydraulic motors, 4 motor cover, 5 power transmission shafts, 6 single-row tapered roller bearings, 7 axle sleeves, 8 emery wheels, 9 drive flange.
The specific embodiment
The end face of the utility model emery wheel 8 is provided with and drives flange 9, and the front end of power transmission shaft 5 is fixedlyed connected with emery wheel 8 by driving flange 9.Power transmission shaft 5 is supported in the front and back ends of axle sleeve 7 by two groups of single-row tapered roller bearings 6.The rear end of power transmission shaft 5 is connected the output of a hydraulic motor 3, this hydraulic motor 3 is arranged in the motor cover 4, motor cover 4 is fixedlyed connected with the rear end of axle sleeve 5, and a fixedly connected lengthening mill bar 2 connects grinding pressure in the rear end of lengthening mill bar 2 and adjusts oil cylinder 1 in the rear end of motor cover 4.
Can take involute spline to connect between hydraulic motor 3 and the power transmission shaft 5, the concentricity height, compact conformation can reduce beating of power transmission shaft.
