Abstract
The utility model discloses an ultrafine grinding assembly for a ball track, which comprises a supporting block and a ceramic grinding block fixed on the supporting block, wherein the supporting block is of rectangular shape; grinding block slots are respectively arranged at two long ends of the supporting block; the ceramic grinding block is fixed in any one of the grinding block slots; the supporting block has a hollow strip-shaped mounting slot; and a ceramic grinding block is respectively fixed in each of the two grinding block slots of the supporting block. The rectangular supporting block is adopted and the ultrafine grinding assembly is fixed with a machine tool through the strip-shaped mounting slot on the supporting block, so that the ultrafine grinding processing for the workpieces with various diameters by using one assembly is realized by adjusting a fixing position on the mounting slot, the time for dismounting and mounting the assembly is saved and the production efficiency is increased, by adopting the ultrafine grinding assembly for the ball track provided by the utility model. Compared with the traditional technology for preparing the assembly in one size for the workpiece in one size, the ultrafine grinding assembly has the advantage that the increase of production cost caused by the preparation for the assemblies in various sizes is avoided.
Description
Technical field
The utility model relates to a kind of bearing processing tool, frock when being used for that specifically raceway surpassed lappingout, that have versatility.
Background technology
In the production as one of mechanical industry basic part bearing, the wherein ultra processing of the mill of raceway face then is again the key link that influences performances such as bearing life and bearing noise.The mill of existing bearing raceway is ultra to be processed as: after the raceway grinding, again it is surpassed lappingout processing.As shown in Figure 2; Existing ultra lappingout frock primary structure form is the circular-arc back-up block that is complementary with the diameter of workpiece; On the inner arc surface of back-up block, be fixed with two potteries and grind piece; The ultra lappingout processing principal mode of raceway grinds piece through two potteries on the frock and raceway is carried out slightly ultra and smart ultra for shifting to ultra lappingout frock to the workpiece of rotation.Adopt the ultra lappingout frock of this form mainly to have following defective: one; The workpiece of each specification must adopt corresponding frock when surpassing lappingout; The versatility of frock is relatively poor, and on lathe, installs frock, removes and will spend the more time, causes the low of production efficiency; Two, the shape of frock is bigger, and weight is heavier, and the inconvenience that causes frock to install, remove on the one hand simultaneously also makes the cost of manufacture of frock bigger.
The utility model content
For overcoming above-mentioned defective, the utility model aims to provide a kind of have better versatility, the ultra lappingout frock of raceway that cost of manufacture is lower, can also enhance productivity greatly after adopting this frock.
For achieving the above object; The technical scheme that the utility model adopts is: the ultra lappingout frock of a kind of raceway; Comprise that a back-up block and the pottery that is fixed on the back-up block grind piece, said back-up block is a rectangle, has one respectively on two long ends of said back-up block and grinds the piece groove; Said pottery grinds piece and is fixed on arbitrary grinding in the piece groove, and said back-up block has the strip mounting groove of a hollow.
Two of said back-up block grind and are fixed with a pottery in the piece groove respectively and grind piece.
Adopted the ultra lappingout frock of raceway of the utility model; Owing to adopted the back-up block of rectangle; Strip mounting groove and lathe through on the back-up block fix, and can realize that a frock surpasses lappingout processing to the workpiece of multiple diameter through regulating the fixed position on the mounting groove; Save the time of demolition, installation frocks; Improved production efficiency, prepared a kind of specification frock with traditional a kind of size workpiece simultaneously and compare, the production cost of having avoided causing because of the frock of preparing plurality of specifications increases.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of the ultra lappingout frock of existing bearing raceway;
Fig. 3 is a kind of example structure sketch map of the utility model.
Among the figure: the 1-back-up block, the 2-pottery grinds piece, and 3-mounting groove, 4-grind the piece groove, the 5-workpiece.
The specific embodiment
As shown in Figure 1; The utility model discloses the ultra lappingout frock of a kind of raceway; Comprise that a back-up block 1 and the pottery that is fixed on the back-up block 1 grind piece 2, its innovative point is that mainly said back-up block 1 for rectangle, has one respectively to grind piece groove 4 on two long ends of said back-up block 1; Said pottery grinds piece 2 and is fixed on arbitrary grinding in the piece groove 4, and said back-up block 1 has the strip mounting groove 3 of a hollow.In practical operation, can adopt two frocks that workpiece 5 is surpassed lappingout processing.When making concrete work, be attached to the back-up block 1 of one of them frock on the lathe earlier, back-up block 1 is an angle with horizontal direction; And make and a end that pottery grinds piece 2 is housed towards workpiece 5 directions; Pass mounting groove 3 through bolt, tentatively tight a bolt, frock is fixed on the lathe; Also being attached on the lathe of another frock; Back-up block 1 on this frock is opposite angle with back-up block 1 on the previous frock, also makes a end that pottery grinds piece 2 to be housed towards workpiece 5 directions, regulates two potteries and grinds piece 2 formed angles; Workpiece 5 diameter that make two potteries grind the required processing of angle of piece 2 formation are complementary; Tentatively tight a bolt then, frock tentatively is fixed on the lathe, draw close workpiece 5 to two frock directions; Regulate the angle and the overhang of two frocks again; Make two potteries on the frock grind the periphery of piece 2 vertical sturdy workpiece 5, tightening two bolts on the frock respectively fully, can surpass lappingout processing again workpiece.
As shown in Figure 3, if adopt single frock workpiece to be surpassed 5 lappingout adds, usually back-up block 1 horizontal fixed; Grind piece 2 to pottery on the back-up block 1 towards workpiece 5 directions, bolt passes mounting groove 3, tentatively tights a bolt; Grinding piece 2 to workpiece 5 to pottery again draws close; Deng pottery grind the periphery of piece 2 and workpiece 5 vertical sturdy after, tight a bolt fully again, can carry out the ultra lappingout of workpiece 5 and process.
The ultra lappingout frock of the raceway of the utility model can also adopt following mode: two of said back-up block 1 grind and are fixed with a pottery in the piece groove 4 respectively and grind piece 2.Like this, after one of them pottery ground piece 2 wearing and tearing excess, through counter-rotating back-up block 1, the pottery on the other end grinds piece 2 can proceed ultra lappingout processing, makes the life-span multiplication of one pair of frock.
