Description

Automatic dressing structure of multi-axis tool grinder

The present invention relates to the technical field of the automatic dressing structure of a multi-axis tool grinder, in particular to a multi-axis tool that can perform automatic dressing operations on the processing grinding wheel in real time during the processing process, which can greatly save manpower and time, thereby effectively improving work efficiency The automatic trimming structure of the grinder.

Generally, when the conventional multi-axis tool grinder is processing, it is usually planned to install 1~4 processing grinding wheels with different numbers on the processing head according to the needs of the processing process. Cooperate so that it can complete the processing operation at one time. However, in the continuous machining process, the grinding wheel is often deformed due to abrasion and cannot be used, or the pores are blocked by iron filings, which affects the processing efficiency. Once the processing wheel is deformed or blocked by the pores , You need to stop the machine first, then remove the processing wheel, and then go to a dressing machine to manually dress or grind the surface to a certain depth to remove surface pores and impurities, and finally put the trimmed grinding wheel back and continue processing . In this way, it not only takes a lot of manpower and time to repair the processing grinding wheel, but also frequent shutdowns and disassembly operations will seriously affect the production capacity and cause the work efficiency to be very low.

The main purpose of the present invention is to solve the problem of the conventional multi-axis tool grinder When the processing wheel is deformed or the pores are blocked, it needs to be manually removed and then another trimmer is used for manual trimming, which leads to many problems such as high labor costs and poor work efficiency.

The automatic dressing structure of the multi-axis tool grinder of the present invention includes a machine table, a clamping device, a processing device and a dressing device. Wherein, the clamping device includes a work platform that can be displaced and rotated in a first horizontal direction on the machine platform. The work platform has a chuck and a chuck driver that drives the chuck to rotate. The chuck can For clamping the workpiece to be processed. The processing device includes a processing head that can be moved and raised in the second horizontal direction on the machine table. The processing head has a processing drive and is mounted on the processing drive and can be driven to rotate to process the processing piece. Processing grinding wheel. The dressing device includes a seat, a dressing drive and a plurality of dressing grinding wheels. The bearing is combined with the work platform, the dressing drive is arranged on the bearing, and the plurality of dressing grinding wheels can be driven to rotate coaxially by the dressing drive. , And the plural dressing wheels have different outer diameters.

The automatic dressing structure of the multi-axis tool grinder provided by the present invention can be linked to the relative displacement and contact of the plurality of processing grinding wheels and the dressing grinding wheel by the clamping device, the processing device and the dressing device, so as to achieve the According to the wear condition of the plural processing grinding wheels, the plural processing grinding wheels can be automatically trimmed in real time, without the need for time-consuming and laborious processes such as shutdown, disassembly, assembly of the processing grinding wheels, and manual trimming, which can greatly save manpower and time. In turn, work efficiency can be effectively and greatly improved.

Please refer to Fig. 1, which shows that the automatic dressing structure of the multi-axis tool grinder according to the present invention includes a machine table 10, a clamping device 20, a processing device 30 and a dressing device 40. among them:

The machine 10 includes a base 11 and a bracket 12 which is arranged on the base 11 and is in the shape of an ㄇ.

The clamping device 20 includes a first horizontal moving base 21, a rotating base 22 and a working platform 23. The first horizontal moving base 21 is combined with the base 11 and can move in a first horizontal direction (such as front and back). The rotating base 22 is rotatably coupled to the first horizontal moving base 21. The working platform 23 is fixed on the rotating seat 22, and the top surface has a chuck 24 and a chuck driver 25 that drives the chuck 24 to rotate. The chuck 24 can hold the workpiece 26 to be processed. Such as the blade of a milling cutter).

The processing device 30 includes a second horizontal moving seat 31 and a processing head 32. The second horizontal moving base 31 is combined with the support 12 and can move in a second horizontal direction (such as left and right) above the working platform 23.
