AI Technical Summary
When the lathes, outer cylindrical grinders and their clamping methods remain unchanged, the machining of the outer cylindrical workpieces cannot be directly clamped with claw clamping or double top clamping.
A workpiece for outer circular processing of ring workpieces is designed. The ring workpiece is fixed on the mandrel by the horizontally arranged mandrel, base sleeve and mating sleeve. The ring workpiece is securely clamped on the mandrel by using a double top tip to the central hole of the clamping end and the threaded segment end of the mandrel.
Without changing the lathes, cylindrical grinders and clamping methods of conventional equipment, the outer circle of the ring workpiece can be effectively worn and polished, solving the clamping problem of outer circle processing of ring workpieces.

Abstract
Description
Technical Field
[0001] This utility model relates to a tooling for machining the outer circle of a circular workpiece, belonging to the field of machining technology. Background Technology
[0002] In the machining industry, the machining of rings is quite common. Common machining methods for the outer diameter of ring workpieces include turning, grinding, and CNC milling. In practice, specialized equipment or fixtures are also used depending on the specific specifications and shape of the ring.
[0003] Among the machining processes on lathes and cylindrical grinders, the most common clamping method is using a chuck with centers or double centers. However, due to the size and shape of annular workpieces, situations arise where direct clamping with chucks or double centers is not possible when machining their outer diameter. Therefore, how can the problem of turning and grinding the outer diameter of annular workpieces be solved without changing conventional lathes, cylindrical grinders, or their clamping methods? Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a tooling for machining the outer circle of a circular workpiece, which can turn and grind the outer circle of a circular workpiece without changing the conventional equipment such as lathes, cylindrical grinders and their clamping methods.
[0005] The technical solution adopted by this utility model to solve the above problems is as follows: a tooling for machining the outer diameter of a circular workpiece includes a horizontally arranged mandrel, on which the circular workpiece is sleeved. One end of the mandrel is provided with a base sleeve, and the other end of the mandrel is provided with a threaded section. A mandrel storage cavity is opened at one end of the base sleeve, and one end of the mandrel is inserted into the mandrel storage cavity. Multiple circumferentially distributed threaded holes are opened on the outer circumference of the base sleeve, and the threaded holes correspond to grooves. Adjusting bolts are screwed into the threaded holes to fix the mandrel and the base sleeve in place. A mating sleeve is sleeved on the other end of the mandrel, and the threaded end passes through the mating sleeve and partially protrudes from it. A locking nut is screwed onto the threaded end. Tightening the locking nut fixes the circular workpiece between the base sleeve and the mating sleeve. Loosening the locking nut allows the mating sleeve and the circular workpiece to move out of the mandrel.
[0006] An annular groove is formed on the outer periphery of one end of the mandrel, and the bottom of the adjusting bolt is located in the groove.
[0007] The other end of the base sleeve is a clamping end, and the clamping end and the threaded end of the mandrel are respectively provided with center holes.
[0008] The mandrel is matched with the mandrel placement cavity.
[0009] The width of the groove matches the outer diameter of the adjusting bolt, and the depth of the groove is greater than 3mm.
[0010] Compared with the prior art, the advantages of this utility model are as follows: A tooling for machining the outer diameter of a circular workpiece, wherein a base sleeve and a mating sleeve cooperate to fix the circular workpiece on a mandrel, and a double center abuts against the center hole at the clamping end and the threaded end of the mandrel, so as to facilitate clamping of the machining equipment. This application has a simple structure and strong applicability, and can machine and grind the outer diameter of a circular workpiece without changing conventional equipment such as lathes and cylindrical grinders and their clamping methods.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0016] like Figure 1 , 2 As shown in Figures 1 and 3, a tooling for machining the outer diameter of a circular workpiece in this embodiment includes a horizontally arranged mandrel 2, on which the circular workpiece 6 is sleeved. A ring-shaped groove 2.1 is formed on the outer circumference of one end of the mandrel 2, and a threaded section 2.2 is formed on the other end of the mandrel 2, coaxially arranged with the threaded section 2. A base sleeve 1 is provided at one end of the mandrel 2, and a mandrel housing cavity 1.1 is formed at one end of the base sleeve 1, coaxially arranged with the base sleeve 1. One end of the mandrel 2 is inserted into the mandrel housing cavity 1.1. Four circumferentially distributed threaded holes 1.2 are formed on the outer circumference of the base sleeve 1, corresponding to the groove 2.1. Adjusting bolts 3 are screwed into the threaded holes 1.2, and are threadedly connected to the threaded holes 1.2, so that the mandrel 2 is fixedly connected to the base sleeve 1, and the bottom of the adjusting bolts 3 is located within the groove 2.1. The other end of the mandrel 2 is fitted with a mating sleeve 4, and the threaded section 2.2 passes through the mating sleeve 4, partially exposing the mating sleeve. A lock nut 5 is screwed onto the threaded section. Tightening the lock nut fixes the annular workpiece between the base sleeve and the mating sleeve; loosening the lock nut moves the mating sleeve and the annular workpiece out of the mandrel.
[0017] The mandrel housing cavity matches the mandrel diameter. The bottom of the mandrel is close to the mandrel housing cavity, facilitating quick positioning of the adjusting bolt into the groove on the mandrel during installation. The width of the groove matches the outer diameter of the adjusting bolt, and the depth of the groove is greater than 3mm. The bottom of the adjusting bolt is locked within the groove, preventing lateral displacement of the mandrel when the locking nut is tightened to secure the ring workpiece.
[0018] There is a gap between the inner wall of the mandrel housing cavity and the outer circumference of the mandrel. The mandrel axis can be finely adjusted by adjusting four evenly distributed adjusting bolts. When the chucks are clamped, if there is an axis deviation caused by uneven wear of the chucks, it can be adjusted by adjusting the bolts without replacing or repairing the original chucks of the equipment.
[0019] The other end of the base sleeve is the clamping end. Center holes are opened at the threaded ends of the clamping end and the mandrel to facilitate the clamping of the machining equipment with double centers.
[0020] The outer diameter of the mandrel and the inner diameter of the ring workpiece are fitted to a tolerance. The outer diameter of the base sleeve and the mating sleeve is smaller than the outer diameter of the ring workpiece after machining, so as to ensure that the ring workpiece is clamped tightly and that the cutting tool or grinding wheel will not come into contact with the tooling during machining.
[0021] This application has a simple structure and strong applicability. It can turn and grind the outer circle of a ring workpiece without changing conventional equipment such as lathes and cylindrical grinders and their clamping methods.
[0022] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
