Description

Technical Field

[0001] The utility model relates to the technical field of tooling for processing support heads, in particular to a tooling for processing support heads on a lathe. Background Art

[0002] The support head is used to fix the workpiece during the processing of products such as the inner and outer rings of bearings; it is an integral design, including an annular integral part at one end, and a split part (also known as the petal part described below) extending, expanding and surrounding the design from the integral part to the other end.

[0003] In the actual production process of the factory, in order to save changeover time, the support head needs to be about 0.5mm larger than the inner diameter of the product before changeover. The support head with a large outer diameter takes a long time to adjust. If the support head can be adjusted to a size close to the inner diameter of the product using an ordinary lathe, the changeover time will be reduced by more than 3 minutes.

[0004] However, in actual operation, when using an ordinary lathe to process the support head, since the support head is divided into petals and the interior is completely suspended, it is easy to damage the support head by a direct school bus. Therefore, it is necessary to make a suitable clamping tool. Utility Model Content

[0046] In this embodiment, the fastener 200 includes a bolt 210 and a screw sleeve 220; the bolt 210 passes through and abuts against the screw sleeve 220, and is used to pass through the surrounding hole 330 to be fixed to the clamping seat 100; the screw sleeve 220 is used to abut against the other end of the support head 300.

[0047] Specifically, the end cap of the bolt 210 abuts against the screw sleeve 220 , and at the same time, the screw sleeve 220 abuts against the outer wall of the hole 330 around the other end of the support head 300 , thereby fixing the support head 300 .

[0048] In this embodiment, the screw sleeve 220 has an integrally formed abutment ring 221 and a penetration tube 222; the abutment ring 221 is used to abut between the other end of the support head 300 and the end cap of the bolt 210; the penetration tube 222 can be penetrated into the tube hole 123.

[0049] Specifically, the penetration tube 222 of the screw sleeve 220 is penetrated in the tube hole 123 in the surrounding hole 330 , which can play a certain supporting and limiting role on the end of the tooling side protrusion 120 .

[0050] In this embodiment, a gasket 400 is further included. The gasket 400 is sleeved on the rough sleeve portion 121 and abuts against the seat body 110 , and is used to receive an end surface of one end of the support head 300 .

[0051] Specifically, the gasket 400 is the part that directly contacts both ends of the support head 300 and has a detachable structure for easy maintenance or replacement. At the same time, the independent single ring structure can disperse the force and is strong and durable.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
