Description

Technical Field

[0001] The utility model belongs to the technical field of bearing processing equipment, in particular to a connecting piece of a floating chuck clamping device used for bearing turning. Background Art

[0002] Bearing ring turning floating chuck tooling, such as Figure 1 As shown, the product clamping and loosening actions are achieved through the cooperation of the rear and front pull rods. The front pull rod passes through the transition plate, the clamp seat, and the positioning plate to drive the spring clamp 5 and the floating claw 9 to clamp and loosen the product, thereby implementing production processing. However, during actual production and processing, we found that the front pull rod connected to the rear pull rod was relatively thin. During long-term actual production and processing, the screws connecting the front and rear pull rods were easily damaged and broken, requiring repeated replacement and repair, which affected production efficiency.

[0006] Furthermore, a first conical surface is provided on the outer side surface of the first opening of the thrust sleeve along the circumferential direction, and a second conical surface is correspondingly provided on the outer side surface of the fixing sleeve along the circumferential direction, and the first conical surface is in abutment with the second conical surface.

[0007] Furthermore, an annular flange is provided on the outer side surface of the fixing sleeve, and an annular step portion is provided on the second opening portion of the sleeve, and the annular step portion is used for the annular flange to be embedded.

[0008] Furthermore, the annular flange is provided with a first threaded hole, and the stepped surface of the annular step portion is correspondingly provided with a second threaded hole. The aligned first threaded hole and the second threaded hole are connected by screws, and a plurality of the first threaded holes are evenly distributed along the circumference of the annular flange.

[0009] Compared with the shortcomings and deficiencies of the prior art, the present invention has the following beneficial effects:

[0010] The utility model provides a connecting piece for a floating chuck clamping device for bearing lathe machining, wherein a rear pull rod is threadedly connected to a fixed sleeve, and an end portion of the rear pull rod penetrates into a thrust sleeve and abuts against an inner end surface of the thrust sleeve, the fixed sleeve limits and fixes the thrust sleeve and the rear pull rod, and the rear pull rod joint fixing seat, the thrust sleeve, the fixed sleeve and the rear pull rod are combined to form a whole.
