Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Embodiment one,

As shown in Figure 1, a kind of turning attachment for bearing machining, including link block 101, clamping jaw 103, the link block 101 both ends are equipped with clamping jaw 103, and two clamping jaws 103 are set to the same side of link block 101, and the folder between two clamping jaws 103 Angle is 30 ° -80 °, and the angle in this embodiment between two clamping jaws 103 is 60 °, and it is optimal selection that angle, which is 60 °, can be to equal Even six positions to bearing inner race or outer ring grip, and make inner ring or outer ring stress equalization, guarantee to process The circularity precision of inner ring or outer ring is high, improves processing quality, the link block 101 is bolted with lathe chuck 3, institute Clamping jaw 103 is stated towards the center of circle of lathe chuck 3, gasket is equipped between the bolt and link block 101.

The link block 101 is arc elongate configuration, can cooperate the shape of lathe chuck 3, more beautiful, using more It is convenient, the space other than lathe chuck 3 will not be additionally occupied, the middle part of the link block 101 is equipped with connecting hole 102, the spiral shell Bolt and connecting hole 102 cooperate, and are fixed at middle part to link block 101, guarantee fixed fastness, it is ensured that two clamping jaws 103 The harmony of stress, to improve the processing quality of product.

The length dimension of the clamping jaw 103 be it is multiple, a length dimension of clamping jaw 103 corresponds in a kind of bearing of model Circle or outer ring, the end face of the clamping jaw 103 are the arcwall face of indent, and concave curved surface can cooperate with inner ring or outer ring, increase Fixed contact area guarantees fixed fastness, since inner ring or the diameter dimension of outer ring or outer ring are a variety of, so using 103 length of clamping jaw it is also different, and the indent radian of 103 end face of clamping jaw corresponding to the inner ring of each diameter or outer ring It is not identical, therefore the bearing of each model corresponds to a kind of fixture of size.

Embodiment two,

It is that the end face of clamping jaw 103 has been equipped with anti-slop serrations 104 with the difference of embodiment one.

As shown in Figure 2,3, the end of the clamping jaw 103 is equipped with anti-slop serrations 104, and the anti-slop serrations 104 are equal along inner concave arc surface Even setting guarantees that clamping is stronger, and the end of the anti-slop serrations 104 is the arc structure of evagination, due in bearing Circle or outer ring be when being processed, and inner ring or outer ring be to rotate, so during the real stress point of 104 end of anti-slop serrations can deviate The heart is set as the arc structure of evagination, can prevent from scratching inner ring or outer ring, protect product.

Embodiment three,

The difference of embodiment three and embodiment two is the shape of link block 101.

As shown in figure 4, the link block 101 is straight elongate configuration, the middle part of link block 101 is equipped with connecting hole 102, described Bolt and connecting hole 102 cooperate.Link block 101 is processed into rectangular parallelepiped structure, processing is simpler, rapid, and manufacture is more held Easily, cost is reduced.

In use, as shown in figure 5, the size of the inner ring or outer ring processed as needed first selects corresponding fixture 1 Then three fixtures 1 are successively installed on lathe chuck 3 with bolt by size, the inner ring processed or outer ring will be needed to be placed into The middle part of lathe chuck 3, then 1 position of alignment jig grips inner ring or outer ring, and starting lathe is to inner ring or outside Circle carries out turning.

Obviously, it is practical without departing from this can to carry out various modification and variations to the utility model by those skilled in the art Novel spirit and scope.If in this way, these modifications and variations of the present invention belong to the utility model claims and Within the scope of its equivalent technologies, then the utility model is also intended to include these modifications and variations.
