Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] see Figure 1 to Figure 8 , the cylindrical grinding tool for cylindrical parts shown in , includes a mandrel 1 and a sleeve 2 sleeved on the mandrel 1, and the outer wall of the sleeve 2 is uniformly provided with eight grooves 21 in the circumferential direction, correspondingly The included angle between adjacent grooves 21 is 45°, and the direction of the grooves 21 is parallel to the axis of the sleeve 2 . Each groove 2 slides with a corresponding slider 3. The mutual contact surface between the slider 3 and the groove bottom of the groove 21 is a wedge surface, and the top surface of the slider 3 and the inner wall of the positioning hole of the cylindrical part The profile is suitable, when the slider 3 moves axially along the groove 21, the distance between its top surface and the axis of the sleeve 2 will become larger or smaller accordingly, and the...

Abstract

The invention discloses an outer circle grinding tool of a cylinder part. The grinding tool comprises a mandrel and a sleeve sleeved on the mandrel, wherein a plurality of grooves are formed in the circumferential direction of the outer wall of the sleeve, the groove direction is parallel to the axis of the sleeve, a sliding block matched with each groove is slidably arranged in each groove, the mutual contact surfaces of the sliding blocks and the groove bottoms of the grooves are inclined wedge surfaces, the top surfaces of the sliding blocks are matched with the inner wall surfaces of positioning holes of the cylinder part, and when the sliding blocks move in the axial direction of the grooves, the distance between the top surface of the sliding blocks and the axis of the sleeve becomeslarger or smaller, and micro adjustment is achieved in any reverse circumference by supporting the cylinder part through the sliding blocks. On the premise of ensuring the clamping requirement of thecylindrical part, the machining center of the cylindrical part on an outer circular grinding bed can be adjusted, and the grinding precision is improved.

Description

technical field [0001] The invention relates to the processing of cylindrical parts, in particular to a cylindrical grinding tool for cylindrical parts. Background technique [0002] see Figure 9 , as a cylindrical part, the journal is an important part to connect the camshaft, and its own high precision is the premise to realize the overall precision of the camshaft after connection. The reference N and R holes at both ends ensure that the camshaft has a good connection coaxiality; the full runout of both ends ensures that the camshaft has a good straightness after connection. [0003] When grinding the outer circle and end face of cylindrical parts on a cylindrical grinder, it is necessary to use tooling to effectively ensure the full run-out requirements and coaxiality requirements of each surface. The existing cylindrical grinding tooling can only meet the clamping requirements of parts, and cannot adjust the center of rotation of cylindrical parts. Contents of the i...
