Description
Technical Field
The utility model relates to a machining makes the field, specifically is a super smart quick-witted deflector roll adjusting device of centerless through type.
Background
Currently, a centerless penetration type superfinishing machine is a high-efficiency superfinishing machine tool, and the working mode of the centerless penetration type superfinishing machine tool is that a pair of guide rollers which are arranged in front and at the back and rotate in a fixed axis mode support a workpiece and drive the workpiece to rotate and simultaneously perform penetration movement from right to left or from left to right; a row of oilstones arranged along the workpiece penetration direction is floatingly pressed on the workpiece from the right above with a certain pressure, and driven by an oscillation device to do high-frequency small-amplitude linear reciprocating motion, so that the workpiece penetrating and passing below the oilstones continuously is superfinished. The centerless penetration type superfinishing machine for superfinishing the conical roller and the cylindrical roller is often regarded as a special machine tool and is respectively referred to as a conical roller superfinishing machine and a cylindrical roller superfinishing machine for short. The centerless penetrating superfinishing machine used for superfinishing the surface of other cylindrical workpieces is often regarded as a general machine tool, namely the centerless superfinishing machine for short. When the centerless penetration type superfinishing machine works, the front-back position relation of the workpiece relative to the oilstone and the contact angle of the workpiece and the guide roller are important factors influencing the superfinishing effect, and the front-back position relation and the contact angle are determined by the front-back positions of the two guide rollers relative to the oilstone, so that the front-back position of the guide rollers can be accurately adjusted, and the centerless penetration type superfinishing machine has important significance for superfinishing. For a cylindrical roller superfinishing machine and a centerless superfinishing machine, a guide roller axis has an inclination angle relative to a horizontal plane, the inclination directions of front and rear guide rollers are opposite, and related to the inclination angles, the roller penetrating direction in the horizontal plane is inconsistent with the guide roller axis direction, and an included angle is formed between the guide roller axis and the roller penetrating direction, so that the adjustment of the front and rear positions of the guide rollers needs to meet the requirement of the included angle to ensure that the rollers penetrate along the arrangement direction of oilstones. Generally, the adjustment of the front and rear positions of the guide roller has two aspects, namely, the requirement of the center distance between the front guide roller and the rear guide roller is met to ensure that the contact angle between a workpiece and the guide roller is correct; and secondly, the tool setting requirement between the workpiece and the oilstone (tool), namely the front and back position requirement of the workpiece relative to the oilstone is met. When the centerless penetration type superfinishing machine is used, the front and rear positions of the guide roller need to be adjusted after the model of a workpiece is changed or the guide roller is polished. The adjustment of the front and rear positions of the guide roller is an important link in the using process of the centerless penetration type superfinishing machine and is a frequently-occurring machine tool operation behavior. The adjustment of the guide roller of the centerless penetration type superfinishing machine is mainly the adjustment of the front-rear position, and therefore, the guide roller front-rear position adjustment is often simply referred to as guide roller adjustment without causing misunderstanding, and the guide roller adjustment device is also generally referred to as a guide roller front-rear position adjustment device.

When the front and rear positions of the guide roller are adjusted by the conventional centerless penetration type superfinishing machine, whether the front and rear positions of the workpiece relative to the oilstone are proper or not is observed by an operator through naked eyes, and whether the guide roller is adjusted in place or not is judged by combining vernier caliper or feeler gauge measurement of the center distance of the front and rear guide rollers. Because the contact surface of the oilstone and the workpiece is an arc surface, whether the contact front and back positions of the oilstone and the workpiece are proper or not is difficult to judge accurately by the visual observation of an operator, and the visual observation and the adjustment operation cannot be carried out simultaneously, the adjustment method has low precision, poor consistency and inconvenient operation. In addition, the method for measuring the center distance between the front guide roller and the rear guide roller is carried out by measuring tools such as a vernier caliper or a feeler gauge, and is inconvenient. With the continuous improvement of the superfinishing requirement, the guide roller adjusting precision and the operation convenience of the existing device and method are difficult to meet the superfinishing requirement of modern high-precision parts.

When the front and rear positions of the guide roller are adjusted by the conventional centerless penetration type superfinishing machine, whether the front and rear positions of the workpiece relative to the oilstone are proper or not is directly observed by an operator, and whether the guide roller is adjusted in place or not is judged by combining vernier caliper or feeler gauge measurement of the center distance of the front and rear guide rollers. Because the contact surface of whetstone and work piece is the arc surface, whether the position is suitable before and after both contacts, rely on operator's naked eye observation to judge the accuracy very difficultly, consequently, the adjustment accuracy is low, and the uniformity is poor. The utility model discloses an aspect utilizes displacement sensing and display module and special calibration subassembly, carries out accurate measurement to the front and back position data of front and back deflector roll both sides relative to the oilstone to show on the screen through displacement signal processing and digital display module; on the other hand, according to the adjustment requirements of the front and rear positions of the workpiece relative to the oilstone and the center distance of the front and rear guide rollers, calculating and determining guide roller position design values according to known parameter values such as the diameter of the calibration diameter disc 2012 in the special calibration rod suite 201, the thickness of the calibration flat plate 202, the thickness of the oilstone 4, the thickness of the feeler gauge and the like; therefore, when the guide roller is adjusted, as long as the guide roller position data displayed on the screen reaches the design value, the front and back positions of the workpiece relative to the oilstone and the center distance of the front and back guide rollers can be accurately ensured. Because avoided current method visual observation and judged whether the oilstone is correct with work piece arc contact surface position this kind of human factor's influence, the utility model discloses position adjustment is not only the precision height around the deflector roll, and the uniformity is good moreover.
The utility model discloses the deflector roll position data that the device was measured and was shown are scientific and reasonable. First, the guide roller fore-and-aft position data is the position data of the guide roller relative to the oilstone, and the fore-and-aft position of the workpiece is completely dependent on the fore-and-aft positions of the two guide rollers, so that the data can accurately reflect the fore-and-aft position of the workpiece relative to the oilstone. When the front and rear position data of the guide roller are calibrated, the position of the calibration flat plate represents the position of the oilstone, the axis of the calibration rod represents the axis of the guide roller, the standard diameter disc, the thickness of the calibration flat plate and the feeler gauge on the calibration rod have accurate sizes, and the guide roller displacement measured by the displacement sensor is also accurate, so that the guide roller position data obtained when the guide roller is adjusted after calibration is the accurate position data of the guide roller relative to the oilstone. Secondly, the utility model discloses a deflector roll position data has 4, is the position data on both sides about the deflector roll around respectively, consequently can judge the centre-to-centre spacing and the deflector roll axis of the front and back deflector roll left and right sides and the contained angle of oilstone array orientation in the horizontal plane according to these data accuracy. And again, the utility model discloses an among the position adjustment drive assembly, control both sides and set up the screw nut pair that has unique structural feature to set up the unique connected mode of nut and deflector roll extension board, make its position to the front and back deflector roll left and right sides adjust respectively, this cooperatees with 4 displacement sensor's setting, can satisfy the adjustment requirement of front and back deflector roll left and right sides centre-to-centre spacing and axis and oilstone array orientation contained angle in the horizontal plane well. Finally, the utility model discloses position data's around the deflector roll accurate measurement and digital display based on displacement sensor can guarantee the uniformity of position adjustment precision around the deflector roll.
Take the guide roller adjustment of the tapered roller superfinishing machine as an example. In most cases, the adjustment requirements of the front and back positions of the superfinishing machine guide roller are as follows: the thickness centers of the left and right oilstones are aligned with the center of the circle of the workpiece front and back, the center distance between the front guide roller and the rear guide roller is S, and the axes of the front guide roller and the rear guide roller in the horizontal plane are parallel (namely, the center distances of the left side and the right side of the front guide roller and the rear guide roller in the horizontal plane are equal). The positional relationship between the front and rear guide rollers and the workpiece and the oilstone when adjusted in place is shown in fig. 5. When the position data of the front guide roller and the rear guide roller is marked to be zero, the position relation among the components of the special marking assembly is shown in figure 6. According to the adjustment requirement, the utility model discloses confirm the calculation method of both sides position design value about the front and back deflector roll as follows.
The diameter of a calibration diameter disc 2012 in the special calibration rod suite 201 is Db, the thickness of a calibration flat plate 202 is Hb, the thickness of the oilstone 4 is Hs, the thickness of a feeler is Hc, designed values of the positions of front and rear guide rollers are respectively represented by Sq and Sh, the distances from the centers of the front and rear guide rollers to an oilstone installation datum are respectively represented by Sdq and Sdh, when the calibration rod is respectively arranged on a front guide roller bearing seat and a rear guide roller bearing seat, the distances from the center of the standard diameter disc to the calibration flat plate installation datum are respectively represented by Sbq and Sbh, and when the oilstone installation datum and the calibration flat plate installation datum are overlapped, the following calculation formula can be obtained according to the geometrical relationship shown in FIGS. 5 and 6:
Sq＝Sdq-Sbq
Sh＝Sdh-Sbh
the calculation formula of the front and rear guide roll position design values Sq and Sh can be obtained from the above calculation formula
When the guide roller of the tapered roller superfinishing machine requires that the center distance between the front guide roller and the rear guide roller is not equal on the left side and the right side, the designed values of the positions of the guide rollers on the left side and the right side are not equal, and the left side and the right side can be calculated respectively by referring to the method, which is not difficult for a person skilled in the art.
For a cylindrical roller superfinishing machine and an excircle superfinishing machine, the axis of a front guide roller and the axis of a rear guide roller have equal inclination angles with opposite inclination directions relative to the horizontal plane, so that a small included angle is formed between the axis of the guide roller in the horizontal plane and the penetrating direction of the roller, and the penetrating direction of the roller is consistent with the arrangement direction of oilstones, the axis of the guide roller and the arrangement direction of the oilstones must have the same small included angle, so the designed values of the guide rollers at the left side and the right side are not equal, and the left side and the right side can be respectively calculated by referring to the method, which is difficult for technicians in the field.
It should be noted that, although the present invention has been described with reference to the above embodiments, the present invention may have other embodiments. Various modifications and changes may be made by those skilled in the art without departing from the spirit and scope of the invention, and it is intended that all such modifications and changes fall within the scope of the appended claims and their equivalents.
