Abstract
The invention relates to a grinding tool for the perpendicular error of a long bearing inner ring. According to the technical scheme provided by the invention, the grinding tool for the perpendicular error of the long bearing inner ring comprises an annular clamp sleeve, a magnetic pole and outer circle supports, wherein the annular clamp sleeve is sleeved on a long inner ring; the circumferential wall of the annular clamp sleeve is provided with at least one through hole; a fastening screw for fixing the long inner ring is arranged in each through hole; the magnetic pole is used for fixing the annular clamp sleeve; one end face of the annular clamp sleeve is absorbed and fixed by the magnetic pole and the annular clamp sleeve is driven to rotate by the magnetic pole; at least two outer circle supports are used for positioning the annular clamp sleeve and uniformly distributed on the outer circumferential side of an annular positioning sleeve; and a certain gap is formed between each outer circle support and the annular clamp sleeve. The grinding tool has a simple and artful structure, high grinding efficiency and high accuracy. After being ground by the grinding tool, the perpendicular error of the long bearing inner ring can be corrected accurately, so that the size and accuracy of the next process are ensured.
Description
Technical field
The invention belongs to the clamp fixture technical field, relate to a kind of reconditioning process unit assembly, specifically is a kind of bearing length inner ring vertical difference reconditioning frock.
Background technology
Bearing ring mainly comprises inner ring and outer ring; the structure of bearing ring as shown in Figure 1; it has outer diameter D and two dimensional parameters of width B; for general bearing; the size of outer diameter D usually can be bigger than the size of width B; but also have the width B of many nonstandard bearings bigger than the size of outer diameter D, such bearing ring is a long lasso (as shown in Figure 2).
For guaranteeing the size and the precision of later process (as mill endoporus, mill raceway groove), the end face of bearing ring need keep vertical with external diameter.But for long inner ring, the topmost defective of its existence is exactly end face and axle center out of plumb, is the shape of parallelogram shown in Figure 3 easily.And produce after this form error, on existing double-ended grinding machine and external diameter centerless grinder, no matter the reconditioning how many times all can not be corrected its error effectively.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of simple and ingenious structure, grinding efficiency height, bearing length inner ring vertical difference reconditioning frock that precision is good are provided, bearing length inner ring vertical difference after this reconditioning frock reconditioning can obtain well proofreading and correct accurately, guarantees the size and the precision of later process.
According to technical scheme provided by the invention, described bearing length inner ring vertical difference reconditioning frock comprises annular holder cover, magnetic pole and cylindrical supporting; The annular holder cover is used to be enclosed within long inner ring, offers at least one through hole on the perisporium of annular holder cover, and the holding screw that is used for fixing long inner ring all is housed in each through hole; Magnetic pole is used for fixing the annular holder cover, an end face of magnetic pole absorption stationary annular anchor clamps cover, and drive the rotation of annular holder cover; The cylindrical supporting is used to locate the annular holder cover, and cylindrical is supported to rare two, and at least two cylindrical supportings are evenly distributed on the outer circumferential side of circular orientation cover, leaves certain interval between cylindrical supporting and the annular holder cover.
As a further improvement on the present invention, the head end of described holding screw cooperates the location with the raceway groove of long inner ring, and the head end of holding screw is made as circular arc.
As a further improvement on the present invention, described magnetic pole is provided with the chamber of indent, and the end of long inner ring is contained in this indent chamber.
The present invention compared with prior art, advantage is: simple and ingenious structure, grinding efficiency height, precision are good, and the bearing length inner ring vertical difference after this reconditioning frock reconditioning can obtain well proofreading and correct accurately, guarantees the size and the precision of later process.

Fig. 1 is the structural representation of plain bearing inner ring.
Fig. 2 is the structural representation of bearing length inner ring.
Fig. 3 is the structural representation that has the bearing length inner ring of form error.
Fig. 4 is for adopting the machining state schematic diagram of reconditioning bearing length inner ring of the present invention.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure, described bearing length inner ring vertical difference reconditioning frock mainly is made up of parts such as annular holder cover 1, holding screw 2, magnetic pole 7 and cylindrical supportings 6.Described annular holder cover 1 is used to be enclosed within long inner ring 3, on the perisporium of annular holder cover 1, offer at least one through hole, holding screw 2 all is housed in each through hole, when long inner ring 3 is contained in the annular holder cover 1, holding screw 2 inside precessions, the head end of holding screw 2 compresses the outer wall of long inner ring 3, thereby long inner ring 3 is fixed as one with annular holder cover 1.Described magnetic pole 7 is used for fixing annular holder cover 1, an end face of magnetic pole 7 absorption stationary annular anchor clamps covers 1, driving annular holder cover 1 during magnetic pole 7 rotations rotates, long inner ring 3 rotations that annular holder cover 1 and then drive are fixed as one with it are so that the end face of 5 pairs of long inner rings 3 of emery wheel carries out reconditioning processing.Described cylindrical supports 6 and is used to locate annular holder cover 1, and cylindrical supporting 6 has two at least, and at least two cylindrical supportings 6 are evenly distributed on the outer circumferential side of annular holder cover 1, can not occur departing from during with 1 work of assurance annular holder cover.Leave certain interval between described cylindrical supporting 6 and the annular holder cover 1, can not support 6 contact frictions when rotated with cylindrical to guarantee annular holder cover 1.
As shown in Figure 4, the head end of described holding screw 2 cooperates the location with the raceway groove 4 of long inner ring 3, and the head end of holding screw 2 is made as circular arc, with further raising fixed effect, guarantees the reconditioning precision.Because the width of long inner ring 3 width than annular holder cover 1 usually is big, when utilizing the end face of magnetic pole 7 absorption annular holder covers 1, the end of long inner ring 3 tends to push up magnetic pole 7, make magnetic pole 7 and annular holder cover 1 can't adsorb fixing, so preferably be provided with the chamber 8 of indent on the magnetic pole 7 among the present invention, the end of long inner ring 3 can be contained in this indent chamber 8, thereby effectively overcomes the problems referred to above.
As shown in Figure 4, during concrete the use, at first will exist the long inner ring 3 of form error to put into annular holder cover 1, utilizing holding screw 2 to tighten fixes, the axle center of this duration inner ring 3 is vertical with the end face of annular holder cover 1, annular holder is overlapped on the magnetic pole 7 that 1 end face is absorbed and fixed at grinding machine, grind an end face of long inner ring 3 earlier, regrind after to the greatest extent another end face of long inner ring 3 of spark mill, after reconditioning, the axle center of long inner ring 3 is vertical mutually with end face, like this, just can reach the requirement of process stipulation.
