Abstract
The utility model belongs to a tool, and particularly relates to a workpiece excircle centering tool for machine tool lathing. The excircle centering tool is composed of a support block, a roller, a pin shaft and a shaft retaining ring. The excircle centering tool is characterized in that the support block is a square bar-shaped iron block of which the front end is provided with an open groove, and the support block is provided with a through hole in a direction perpendicular to the groove; the roller is a cylinder of which the center is provided with a hole, and the height of the roller is matched with the groove width of the support block; and the excircle of the pin shaft is matched with the through hole at the front end of the support block, and both ends of the pin shaft are provided with retaining ring grooves. The utility model has the following beneficial effect: by using the calibration tool adopting the scheme, a lathed part can be calibrated conveniently and quickly, and the calibration accuracy is high.
Description
Technical field
The utility model belongs to a kind of instrument, the cylindrical centering instrument of workpiece when relating in particular to the lathe Vehicle Processing.
Background technology
Usually can relate in industries such as hot-water heating, fire-fightings cylindric objects such as copper rod and pipe fitting are carried out turning processing, it is being processed timing,, generally adopt visual method to adjust because workshop has special school to transfer instrument at present.Because partly the allowance of product is less, adopts this method to add and to cause scrapping of product because of the correction accuracy difference man-hour.
Summary of the invention
The utility model is the cylindrical centering instrument that a kind of workpiece is provided in order to address the above problem.
The scheme of the utility model is achieved in that a kind of excircle of workpiece centering instrument, is made up of rest pad, roller, bearing pin and shaft block ring, it is characterized in that: said rest pad is that front end is provided with open slot side's bar shaped iron block, and is provided with through hole in the vertical channel direction; Said roller center is provided with the cylinder in hole, and its height cooperates with the rest pad groove width; Said bearing pin cylindrical cooperates with rest pad front end through hole, and two ends are provided with circlip groove.
The beneficial effect of the utility model is: adopt the aligning tool of such scheme, it is suitable, quick that workpiece school modulation must be made things convenient for, and correction accuracy is high.
Description of drawings
Fig. 1 is the front view of utility model.
Fig. 2 is the structural representation of utility model.
Among the figure: 1, roller, 2, rest pad, 3, shaft block ring, 4, bearing pin.
The specific embodiment
Below in conjunction with accompanying drawing, the technical scheme of the utility model is further described:
As shown in Figure 1, roller 1 with after rest pad 2 cooperates, is reinstalled bearing pin 4, and spacing with shaft block ring 3.During use with rest pad clamping angle on lathe, and its roller is moved to workpiece centre, overlap with the lathe pivot until the excircle of workpiece center.
