Problems solved by technology

The existing five processes of drilling the central oil hole of the connecting rod, expanding the central oil hole, drilling through the oil hole, drilling the threaded bottom hole and tapping the thread are processed separately by five ordinary machine tools, which require five times of positioning and clamping. Based on shape positioning, five times of clamping, it is impossible to be unified, and it is difficult to guarantee the consistent position of the processed holes. Processing with a single machine tool cannot meet the needs of mass production

Embodiment Construction

[0011] Compared with Figure 1, figure 2 , its structure is that the overall protection of the machine tool 1 is installed on the integral casting bed 9, the power head 2 connected with the threaded bottom hole of the four-axis drill is installed on the integral casting bed 9 through the power head seat 8, and the four-axis movable drilling template 3 is installed on the integral casting bed 9 through the guide rod It is connected with the four-axis power head 2. Due to the small diameter of the processed hole and the overhang of the drill bit, the movable drilling template 3 is added to ensure the position of the drilling hole. The rotary table 4 is fixed on the integral casting bed 9, and the fixture part 6 is fixed on the On the rotary table 4, the rotary table rotates once to complete the work of one station. The oil rotary distributor 5 is fixed at the center of the rotary table 4, the moving coil rotates with the rotary table 4, and the fixed ring is fixed and does not ro...

Abstract

The invention relates to a special connecting rod drilling machine with eight stations. The machine tool is wholly and protectively arranged on an integrated casting machine tool bed, a rotary worktable is fixed on the integrated casting machine tool bed, a fixture part is fixed on the rotary worktable, an oil rotary distributor is fixed in the center the rotary worktable, a unit head and a base seat of a loading and unloading device are fixed on the integrated casting machine tool bed; a loading device, a two-axis drilling through center oil hole unit head, a two-axis drilling and counterboring center oil hole unit head, a two-axis drilling center oil hole unit head, an unloading device, a four-axis tapping unit head and a blowing detecting device are all fixed on the unit head and the base seat of the loading and unloading device; a two-axis running drilling template is connected with the two-axis drilling through center oil hole unit head via a guide rod, and a four-axis running drilling template is connected with a four-axis drilling connecting thread bottom hole unit head via the guide rod. The special drilling machine has the advantages of completing processes that need to be processed by a single device in a machine tool, avoiding repetitive position error, simplifying the process, meeting the processing requirement of high efficiency and high precision of parts and being suitable for mass production.

Description

Technical field: [0001] The invention relates to a special machine tool for processing small holes, which is suitable for drilling the central oil hole of the connecting rod, expanding the central oil hole, drilling through the oil hole, drilling the threaded bottom hole for connection and the connecting rod eight-station drill for tapping. The hole special machine belongs to the technical field of special machine tools. Background technique: [0002] The connecting rod is one of the important parts in the piston compressor, the quality of this part directly affects the performance of the compressor. The existing five processes of drilling the central oil hole of the connecting rod, expanding the central oil hole, drilling through the oil hole, drilling the threaded bottom hole and tapping the thread are processed separately by five ordinary machine tools, which require five times of positioning and clamping. Based on shape positioning, five times of clamping, it is impossi...
