Description

Double-end multi-tool drilling and milling machine

technical field

The utility model relates to the field of metal cutting numerical control machines, in particular to a double-end multi-cutter drilling and milling machine, which is used for end cutting of drilling, sleeve, scraping, milling and tapping under the non-rotating state of workpieces. The milling machine usually has 2 power heads and uses a compound tool to process two end faces, chamfers and center holes. Repeated positioning accuracy is affected by the screw rod, preferably within 0.01MM, but the number of tools is relatively small, and other stations are required for supplementary processing.

The advantage of processing such parts in machining centers is that the tools can be fully used, but for camshafts, 6 to 7 tools can be processed, and the excess is of no practical use. It takes 4 seconds for a tool change. If 7 tools are used as an example, The total time for each end is 28 seconds. Since the machining center processes one end and one end separately, it takes 56 seconds for a part to change the tool, which is close to 1 minute, and the cutting time is not counted separately.

Background technique

In the prior art, people will use vertical and horizontal machining centers, milling machines, etc. to complete the machining of the end face of the camshaft, but only one end can be processed, and the tool change time is relatively long, and the milling machine can process both ends due to the carriage The length is limited, the X-direction displacement of multi-power head processing is too long, the equipment is huge and the displacement positioning accuracy is deviated, and the tool is easily damaged.

Utility model content

In order to solve the problems of the prior art, the utility model provides a double-ended multi-tool drilling and milling machine, which combines the principle of a turning tool rest, reduces tool changing time, and has high positioning accuracy.

The utility model provides a double-ended multi-cutter drilling and milling machine, which includes a base with an inclination angle of 45° to the horizontal plane, which is convenient for chip removal. A left cross carriage and a right cross carriage are fixed on the base, wherein the left cross carriage is connected with a left feed servo motor, and the right cross carriage is connected with a right servo feed motor; the left cross carriage and the right cross carriage A power tool rest is respectively installed on the carriage, and there are at least twelve power tool holders installed on the power tool holder, and each power tool holder is equipped with different tools according to the type of the camshaft part to be processed; On the base, there is a hydraulic tooling fixed between the left cross carriage and the right cross carriage. The hydraulic tooling is fixed with a part abutment that can be manually fixed. The part abutment is fixed with a V-shaped frame, a self-positioning cylinder and a hydraulic rotary pressure head. , The camshaft parts to be processed are fixed by the V-shaped frame.

The utility model also provides a working method of a double-ended multi-cutter drilling and milling machine, comprising the following steps:

1) Place a camshaft part to be processed on the V-shaped frame, the positioning cylinder pushes the camshaft part to be processed to the set position, and the hydraulic rotary pressure head turns over and presses;

2) After the camshaft parts to be processed are clamped, the CNC system judges whether the clamping is in place. If it is not sure, the alarm should be manually intervened. If it is confirmed that the clamping is in place, go to step 3);

3) Select the tool according to the NC program, the left feed servo motor controls the power tool holder on the left cross carriage to send the power tool seat to the processing position for left end processing, and the right feed servo motor controls the power knife on the right cross carriage The frame sends the driven tool holder to the processing position for processing at the right end, and the processing on the left and right is carried out at the same time, but it does not end at the same time. The processing beats of each end are different, and the longest processing cycle time is calculated.

The beneficial effects of the utility model are:

1. Both ends of the utility model work at the same time, which is similar to the milling method, but there is no radial tool feed in the X direction, so there is no repeated positioning error in the radial dimension. The tool has 12 positions and the tool position is completely satisfied. The camshaft at both ends Processing requirements. From the perspective of tool change time, the servo hydraulic power tool holder only has an adjacent tool change time of 0.4 seconds, and seven tool changes are only 1/10 of the machining center's time of 2.8 seconds. Due to the simultaneous processing of both ends, the total tool change time is only 2.8 seconds, and the cutting time is the same as above. Cutting time is basically the same for all devices.

2. The tooling of this utility model is also unique. The parts should be placed on the V-shaped frame, and the mechanical structure on it will be automatically aligned according to the process requirements, and the workpiece will be tightly pressed on the On the V-shaped frame, there is a hardened tooth surface on the V-shaped frame, which can resist strong axial cutting and ensure axial precision.
