Drawings
FIG. 1 is a schematic diagram of the structure of the present invention;
in the figure:
1. the grinding wheel unit comprises a grinding wheel unit body, a unit frame, a transverse moving arm, a carrier roller, a swinging arm, a telescopic device, a grinding trolley, a rail, a dragging wheel, a lifting motor and a lifting motor.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, the embodiment of the invention comprises a polishing device for locally polishing the uneven wall thickness of the blank pipe, and a polishing trolley 7 for transferring the blank pipe and adjusting the polishing surface of the blank pipe to match with the polishing device for polishing; the grinding device comprises a grinding wheel unit 1, a unit frame 2 and a transverse moving arm 3, wherein the grinding wheel unit 1 is connected with the unit frame 2, the unit frame 2 is connected to the front end of the transverse moving arm 3, and the transverse moving arm 3 only drives the unit frame 2 to do linear telescopic motion, and the grinding wheel unit 1 does arc motion relative to the unit frame 2; the grinding carriage 7 is provided with a carrier roller 4 for radially rotating the blank pipe. In the embodiment of the invention, firstly, a blank pipe to be ground is shifted onto a grinding trolley 7, then the grinding trolley 7 runs below a grinding wheel unit 1 and stops, the grinding trolley 7 reaches a processing station, and then the grinding wheel unit 1 performs reciprocating grinding movement on the surface to be repaired of the blank pipe through the matching of a traversing arm 3 and a unit frame 2 until finishing grinding. The main motor of the grinding wheel set 1 of the embodiment adopts 7.5KW power. The surface grinding amount is more than or equal to 0.2mm in each pass, and is controlled according to the air pressure and the grinding head moving speed of the grinding wheel set 1. The moving speed of the grinding head is 0.8-10 m/min, the frequency conversion of the moving speed of the grinding head is adjustable, and the surface roughness Ra 25-um-12.5 um after grinding. The polishing area and the non-polishing area have no step shape, and have the functions of fixed-point polishing, local polishing and full polishing. The machine set frame 2 is rotationally connected with a swing arm 5 and a telescopic device 6, the end part of the swing arm 5 and the telescopic end of the telescopic device 6 are hinged with the rotating shaft of the grinder set 1, the horizontal height of the setting position of the telescopic device 6 is higher than the setting position of the swing arm 5, and the telescopic device 6 is implemented by adopting a telescopic cylinder. When the traversing arm 3 linearly pushes the machine frame 2 to the direction of the grinding trolley 7, the telescopic end of the telescopic device 6 is shortened to lift the grinding wheel set 1, and the grinding wheel set 1 performs arc-shaped lifting movement under the limit of the swinging arm 5, so that the included angle between the connecting line of the grinding point of the grinding wheel set 1 and the rotation axis of the grinding wheel set 1 and the movement direction of the traversing arm 3 is always more than 90 degrees and less than 180 degrees. The grinding wheel set 1 is subjected to arc grinding from the upper side surface of the blank pipe, if linear grinding is carried out from the vertical direction, the descending amount of the grinding wheel set 1 is difficult to control, the grinding amount is easy to be excessive because the travel is excessive, when the travel of the grinding wheel set 1 is excessive, the grinding wheel set 1 is also scratched from the surface of the leather material pipe along a certain tangential angle, the grinding amount in the mode is very limited, and the arc grinding of the grinding wheel set 1 is driven by two parts which move linearly, so that the actual movement travel from the travel of the traversing arm 3 and the telescopic device 6 to the grinding wheel set 1 is reduced, the control required precision is correspondingly enlarged, and the control precision is improved.
The coping trolley 7 comprises a trolley which is arranged on the track 8, and the bottom of the trolley is provided with a tug 9. The tug 9 is connected with the trolley through a lifting motor 10, and the lifting motor 10 is a servo motor. The height of the trolley is adjusted by driving the rack fixedly connected with the tug 9 through the servo motor control gear, so that the distance between the blank pipe and the sand wheel set 1 can be adjusted, when excessive polishing occurs, the trolley can be lowered and the sand wheel set 1 can be lifted up to be separated at the first time, thus the polishing precision can be ensured, and the separation of the sand wheel set 1 and the blank pipe is slower than the vertical lifting mode due to the arc lifting structure of the sand wheel set 1, so that the lifting adjustment of the trolley is necessary.
The transverse arm 3 comprises a transverse motor, a transverse gear, a transverse rack and a transverse arm, wherein the rack is fixedly connected with the transverse arm, the rack is meshed with the gear, and the gear is connected with the output end of the motor. The speed of the reciprocating linear motion of the traversing arm 3 is automatically adjusted by a frequency converter.
Two carrier rollers 4 are arranged on the grinding trolley 7, the two carrier rollers 4 are reversely rotated, and a placement part for placing a blank pipe is formed between the two carrier rollers 4. The carrier rollers 4 which are arranged in a mutually opposite rotation way can cooperate with the blank pipe to carry out fine adjustment in the actual work so that the surface to be polished can always follow the action of the grinding wheel set 1.
The present embodiment is only for explanation of the present invention and is not to be construed as limiting the present invention, and modifications to the present embodiment, which may not creatively contribute to the present invention as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present invention.
