Background technology
It is very important procedure of processing in the product manufacturing procedure that the rubbing down processing is carried out on the surface of product, especially for roll surfaces such as each big steel mill high, medium and low temperature section furnace roller, technology rollers, behind detonation flame spraying, its coating hardness HV 〉=1100, surface roughness generally about Ra12, does not meet the surface roughness value requirement of the needed all size of steel mill, need carry out rubbing down to its stiff dough and handle, therefore, rubbing down efficient and effect become one of key factor that influences production efficiency and quality.
Existing polishing and grinding head comprises frame, drive motors, driving wheel, driven pulley and abrasive band, and drive motors is installed on the frame, and driving wheel is directly installed on the main shaft of drive motors, and the abrasive band is enclosed within on driving wheel and the driven pulley.Its shortcoming is: because there is certain length in the abrasive band between driving wheel and the driven pulley, cause the abrasive band when rubbing with workpiece, rock in the abrasive band, the force part instability, the sand grains on the abrasive band is little to the cutting force of surface of the work, and rubbing down efficient is low, in practical operation, directly surpass Φ 200mm for roller, the roll surface of its surface roughness Ra≤0.8 is adding the requirement that is difficult to reach expection man-hour.
The utility model content
In order to address the above problem, the utility model provides a kind of simple in structure, rubbing down efficient height, the effective pinch wheel polishing and grinding mechanism of rubbing down.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of pinch wheel polishing and grinding mechanism, comprise feed arrangement and polishing and grinding head, described polishing and grinding head comprises frame, drive motors, driving wheel, driven pulley and abrasive band, it is characterized in that: also comprise a pressing wheel device, the pinch roller of described pressing wheel device is installed on a connection piece, the upper and lower leg of the described connector upper and lower back shaft that is rotatably connected respectively, described upper support axle is fixed on the frame, and described lower support axle and frame flexibly connect.
Further, in the utility model, described feed arrangement comprises the vertical slide carriage that can vertically move, and is arranged on the vertical slide carriage and transversely movable horizontal slide carriage; Described polishing and grinding head is fixed on the horizontal slide carriage.
Further, in the utility model, pinch roller adopts aluminium or steel to make, the elastic ring that its surface coverage has rubber to make.
The beneficial effects of the utility model are:
1, the utility model adopts the scheme of setting up pressing wheel device on polishing and grinding head, makes between abrasive band and the workpiece to fit tightly, and increases the cutting force of abrasive band to surface of the work, improves rubbing down efficient, and the rubbing down better effects if.
2, the utility model is simple in structure, and cost is low, is convenient to promote.
The utility model is particularly useful for working roll and directly surpasses Φ 200mm, and surface roughness need reach the roll surface of Ra≤2.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to schematic diagram;
Fig. 3 is the structural representation of pressing wheel device of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1,2 and 3, a kind of pinch wheel polishing and grinding mechanism, its feed arrangement comprise and are arranged on the vertical slide carriage 5 on the C6163B lathe (among the figure indicate) and are arranged on horizontal slide carriage 4 on the vertical slide carriage 5.The first precise ball screw pair is installed on the body of lathe bed, and vertically moving of vertical slide carriage 5 is to drive the nut drive of the screw mandrel of the first precise ball screw pair by the precise ball screw pair by servomotor.Horizontal slide carriage 4 can laterally slide on the guide rail of vertical slide carriage 5, and horizontal slide carriage 4 is moving by the second precise ball screw subband by another servomotor.
Polishing and grinding head comprises frame 10, drive motors 2, driving wheel 11, driven pulley 8 and abrasive band 9.The right-hand member of frame 10 welds a fixed head 7, and this fixed head 7 is fixed on the horizontal slide carriage 4 by a pressing plate 6.The mobile of polishing and grinding head is to drive it by the vertical slide carriage 5 of the main spindle box driving of lathe to vertically move; Laterally move with moving of horizontal slide carriage 4.
Drive motors 2 is installed in the upper end of frame 10, and driving wheel 11 is directly installed on the main shaft of drive motors 2, and driven pulley 8 is installed in the lower end of frame 10 by bearing, is with abrasive band 9 between driving wheel 11 and driven pulley 8.At the middle part of frame 10 pressing wheel device is installed, the pinch roller 18 of pressing wheel device is installed on a connection piece 19, pinch roller 18 adopts aluminium or steel to make, and the elastic ring (thickness is 10mm-15mm) that its surface coverage has rubber to make is to reduce the vibration between surface of the work and the pinch roller.
