Description

Surface grinding device that facilitates mounting and separation of workpieces {SURFACE GRINDING DEVICE FOR EASY MOUNTING AND DISMOUNTING OF WORKPIECES}

The present invention relates to a plane grinding device that facilitates mounting and separation of the workpiece. More specifically, in the plane grinding device, the workpiece is easily mounted on a station jig for mounting the workpiece and grinding processing is completed. Afterwards, the workpiece mounted on the station jig can be easily separated, and the transfer table on which the station jig is installed can be transported to the operator's location away from the end mill location where grinding is performed, allowing the worker to safely transport the workpiece. It relates to a flat grinding device that is easy to place and separate from workpieces that can be handled at any location.

In general, various grinding machines perform cutting, grinding, or turning workpieces made of metal, etc. using grinding tools such as taps, drills, end mills, and milling cutters.

On the other hand, a plane grinding device is a machine that grinds the plane of a workpiece. Basically, a flat-shaped transfer table capable of adjusting the position of the workpiece is provided on the top of the base structure supported on the ground, and a transfer table is provided on the top of the transfer table. A jig (station jig) is installed to fix the workpiece, and grinding tools such as an end mill for grinding are installed on the top of the workpiece. At this time, in order to disperse grinding chips generated in the process of grinding the workpiece or prevent safety accidents for workers, a housing with a door may be provided to block the outside of the grinding work space and partition the work space.

In the conventional case, there is a problem in that the work of fixing the workpiece to the jig is performed manually by the worker, which takes a lot of work time.

On the other hand, when multiple jigs are provided and several workpieces are grinded at the same time, it takes a lot of work time to fix the workpieces to the jig, and even after grinding is completed, it takes a lot of time to separate the workpieces fixed to the jig again. As work time is consumed, productivity ultimately decreases.

For example, the workpiece before processing used in surface grinding processing is made up of a flat plate shape with a simple structure, and is fixed in a relatively simple way, unlike the workpiece that is fixed by a jig using a vise-like method. . In this case, the plate-shaped workpiece for flat grinding processing is configured to have a slightly larger width than the fitting groove of the station jig to which the form is fixed, and is fixed and separated by interference fitting using a rubber mallet, etc.

Meanwhile, in the conventional plane grinding device, when fixing and separating a workpiece, the worker performs the work while approaching the end mill position where grinding is performed, which requires posture such as bending at the waist. There is a problem of causing muscle loss due to repetitive work, and there is a risk of safety accidents such as contact with grinding tools.

Therefore, there is an urgent need to prepare measures to enable workers to safely and easily handle workpieces in flat grinding devices.
