Technical Field
The invention belongs to the field of hardware tool processing machine tools, and relates to a multi-station grinding machine for grinding azimuth edges and corners of outer side surfaces of pliers heads.
Background
The pliers are very widely used hardware tools, and 4 azimuth angles (i.e. tangential planes) need to be machined and polished on the outer side surface of the pliers head, as shown in fig. 1 and 2, namely a first tangential plane 801, a second tangential plane 802, a third tangential plane 803 and a fourth tangential plane 804. So, firstly, in order to be convenient to use, the volume of the outer surface is reduced, and collision with other objects is avoided when the device is used; secondly, because of the strength, the pliers heads need to bear larger shearing force, so that larger compressive and tensile strength is needed, and the added edges and corners similarly increase the structural strength; thirdly, for aesthetic reasons, a splicing surface is additionally arranged on the surface of the pliers.
In the existing technology for machining the outer side surface of the pliers head, when the pliers are manufactured, the four elements on the pliers are respectively finished by four working procedures one by one, each pliers head needs to be machined four times, and the other pliers head needs to be machined four times, so that the whole pliers claw needs to be machined eight times; the workpiece is repeatedly clamped, the workpiece is repeatedly clamped up and down, the working procedures are required to be circulated, the production efficiency is low, the product quality is not easy to control and unstable due to the repeated up and down clamping of the workpiece, the personnel and equipment investment is high, the production cost is high, the surface of the workpiece is easily damaged due to repeated clamping, and the machining is easily omitted or repeated machining is easily performed in the repeated clamping process.

The invention mainly provides a novel processing grinder for processing the outer side surfaces of the pliers heads, reduces processing procedures and provides technical support for efficient production.
