Problems solved by technology

[0004] The above-mentioned processing of the sawtooth needs to prepare two special equipment, and the saw blade needs to be loaded and unloaded twice during the processing, which requires more manpower and material resources, complicated operation, and slow speed. In addition, due to the existence of installation errors, The secondary loading and unloading has a great influence on the machining accuracy of the saw blade, and the machining accuracy is low

Embodiment Construction

[0023] A three-state positioning mechanism for relief angle grinding of a gear grinding machine provided according to the present invention includes a workbench 1, first, second and third positioning devices 2, 3, 4 and The abutting device 5 located at the lower end of the workbench 1, the second positioning device 3 is 0.25 mm longer than the first positioning device 2, the third positioning device 4 is 1 / 3 tooth width longer than the second positioning device 3, and the abutting device 5 The rear end of the workbench is connected to the rear end of the workbench 1 through a pre-tension spring 6, and the front end only abuts against any one of the first, second, and third positioning devices 2, 3, and 4 each time. When working, the grinding device is installed on the workbench 1. When the abutment device 5 and the first positioning device 2 abut against each other, the low and flat teeth on the trapezoidal alloy circular saw blade can be ground. When the second positioning de...

Abstract

The invention relates to a clearance angle grinding three-state positioning mechanism of a gear grinding machine, which comprises a workbench, first, second and third positioning devices which can be slidably arranged on the front end of the workbench and a pressing device which is arranged at the lower end of the workbench. The rear end of the pressing machine is connected with the rear end of the workbench through a pretightening spring, while the front end of the pressing machine is only pressed against any one of the first, the second and the third positioning devices at a time. The clearance angle grinding three-state positioning mechanism of the gear grinding machine has the advantages of simple operation, fast machining speed and high machining accuracy.

Description

Technical field: [0001] The invention relates to a machine tool for grinding the teeth of an alloy circular saw blade, in particular to a three-state positioning mechanism for the back angle grinding of the gear grinding machine. Background technique: [0002] The trapezoidal tooth alloy circular saw blades used by people include low flat teeth and trapezoidal teeth. The two sides of the flat blade have a side edge with a 45-degree inclination angle. The edge of the flat edge on the trapezoidal tooth is 0.25-0.5mm higher than the edge of the lower flat tooth. When the alloy circular saw blade is cutting, the trapezoidal tooth is used for rough cutting , and then finish cutting by low flat teeth. [0003] In the prior art, the processing of the above-mentioned trapezoidal flat-tooth alloy circular saw blade is generally divided into two steps: the first, the flat blades of the low-flat and trapezoidal teeth are ground on a gear grinding machine; The saw blade with the groun...
