Example Embodiment

[0014] Hereinafter, the present invention will be further described in detail through embodiments with reference to the accompanying drawings.

[0015] Such as figure 1 , figure 2 , image 3 , Figure 4 with Figure 5 As shown, in this embodiment, the whetstone clamp includes a swing head body 1, an oil stone mounting hole 2 and a swing rod 3. The swing head body 1 is provided with a stepped hole 4 along its axial direction, and one end of the swing rod 3 passes through the stepped hole. Connected to the swing head body, a rotating pair is provided between the swing head body 1 and the swing rod 3, and a shaft 31 is provided at one end of the swing rod 3. The shaft 31 is matched with the stepped hole 4 in the swing head body. The diameter is slightly smaller than the inner diameter of the small end of the stepped hole 4, so that there is a clearance fit between the stepped hole 4 and the shaft 31 to form a rotating pair. The length of the shaft 31 is slightly larger than the len...

Abstract

The invention relates to an oilstone clamp for super finishing of a bearing groove. The oilstone clamp comprises a swinging head body, oilstone mounting holes and a swinging rod. A stepped hole is arranged in the swinging head body along the axial direction. One end of the swinging rod is connected with the swinging head body through the stepped hole. A revolute pair is arranged between the swinging head body and the swinging rod. The two oilstone mounting holes are arranged in the swinging head body. The two oilstone mounting holes are arranged in the form of an inverted V at two sides of the axial line of the swinging head body. An oilstone is fixedly mounted in the oilstone mounting holes. Two positions for mounting the oilstone are arranged in the swinging head body of the oilstone clamp for super finishing of the bearing groove, thereby realizing two machining steps of super rough finishing and super fine finishing, simplifying the structure of a machine tool and enhancing the machining efficiency. The holes of the swinging head body and a shaft at the end portion of the swinging rod are in clearance fit, and meanwhile the length of the shaft of the swinging rod is slightly larger than that of the mounting holes in the swinging head body, thereby facilitating the adjustment of the position of the swing head body.

Description

Technical field [0001] The invention relates to mechanical processing equipment, in particular to a bearing channel precision grinding device, in particular to a whetstone clamp for superfinishing bearing channel. Background technique [0002] The super-finishing processing technology of bearing raceway (track) of bearings is a raceway (track) final processing technology commonly used by manufacturers. Due to its high machining accuracy requirements, higher requirements are placed on oilstone and processing technology. . At present, the one-sequence two-step superfinishing method is widely used, that is, bearing raceway (channel) superfinishing is divided into two steps: coarse superfinishing and fine superfinishing. There are two superfinishing heads and two oilstones, respectively. A set of drive mechanism controls the ultra-finishing processing. Therefore, the structure of the machine tool is complicated and the processing efficiency is low. The Chinese utility model patent...
