Problems solved by technology
[0002] Thin-walled sleeve parts, because the outer wall is thin (the average wall thickness is less than 3-5% of the aperture size), and the rigidity is poor, it is difficult to clamp it with traditional fixtures, and it is easy to be clamped and deformed during processing, and Due to the inaccurate honing process, when the honing head is grinding, it is easy to deform and damage the thin-walled sleeve parts, and then the processing fails, and it is easy to damage the parts or tools

Embodiment Construction
[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0021] Such as figure 1 , figure 2 As shown, a honing process of thin-walled sleeve parts, the honing process includes the following steps: ①. Take the tooling used to support the part 100 and install the tooling on the honing machine (the honing machine is a vertical honing machine) superior;
[0022] ②. Take the part 100 to be processed and place the part 100 on the clamping tool for alignment and calibration, and press the aligned and calibrated part 100 flexibly and stabilize it on the tooling; the alignment and calibration method in this step ② includes The dial gauge is adsorbed on the flange of the main shaft of the honing machine, the main shaft is rotated, and the concentricity between the part 100 and the main shaft is calibrated through the dial gauge shown, and the concentricity error is not greater than 0.05mm. The al...

The invention relates to a honing process for thin-walled sleeve parts. The honing process includes the following steps: ①. Take a tool for supporting the part and install the tool on the honing machine; ②. Take the part to be processed and The parts are placed on the clamping tool for alignment and calibration, and the aligned and calibrated parts are flexibly pressed and stabilized on the tooling; ③. Take the honing head and install the honing head on the main shaft of the honing machine; ④. Operate the honing machine Make the honing head honing the parts; through the design and adjustment of the new processing technology parameters, the processing technology requirements of the thin-walled sleeve parts are met, and the parts are flexibly pressed on the tooling, which not only ensures relative fixation, but also allows The workpiece is slightly moved in a small range to compensate for the calibration error of the part. In addition, through internal and external spray cooling, it ensures sufficient cooling of the cutting area and fully controls the temperature of the workpiece to keep it relatively stable.
Description
technical field [0001] The invention relates to a honing process for thin-walled sleeve parts. Background technique [0002] Thin-walled sleeve parts, because the outer wall is thin (the average wall thickness is less than 3-5% of the aperture size), and the rigidity is poor, it is difficult to clamp them with traditional fixtures, and it is easy to clamp and deform during processing, and Due to the inaccurate honing process, when the honing head is grinding, it is very easy to deform and damage the thin-walled sleeve parts, and then the processing fails, and it is also very easy to damage the parts or tools. At present, the honing fixture in the prior art is not only complex in structure and high in manufacturing cost, but also complex in operation when clamping the workpiece, labor-intensive and time-consuming in clamping the workpiece, slow in clamping speed and low in work efficiency, and is also affected by many factors such as material and pressure. Influence, there i...
