Background
The engine guide sleeve is a small-sized precision part matched with an engine cylinder guide pillar, and the current industry mainly adopts CNC to cut and process columnar blanks.
As is well known, in order to perform machining smoothly, a clamping tool must be used to clamp and position a columnar blank. The core component of the currently known universal clamping tool is a tool plate, a plurality of clamping grooves are formed in the two sides of the tool plate along the length direction, and the tool plate is used for embedding upright blanks and then locking the blanks in the clamping grooves by matching bolts and pressing blocks. The worker places the jig plates with the blanks installed in parallel on the supporting blocks of the base, and then the jig plates are pressed and fixed on the supporting blocks through the two cylinder pressing mechanisms on the two sides, and the jig plates can be placed in the CNC to implement machining operation.
After processing parameters and instructions are input into the CNC, a cutting tool of the CNC starts to process the blank layer by layer, and when one layer of guide sleeve is processed, the guide sleeve is taken away from the upper part by a special material taking jig. However, in actual production, we have encountered the following problems:
with the progress of processing, the length of a section of the upper part of the blank extending out of the plane of the jig plate is gradually shortened, in order to ensure the continuous processing, the jig plate is dismounted from the clamping tool after the CNC is shut down by manpower at present, the jig plate is transferred to an outside transition jig to be remounted with each blank, and the blank is ensured to keep a section of the processing section extending out of the plane of the jig plate; or the jig plate is turned over after the blank is transferred to the outer transition jig, so that the lower section of the blank faces upwards, and the blank can be continuously processed. However, no matter what kind of operation, it is time-consuming and labor-consuming, so that the production efficiency is greatly reduced.
