Description

TECHNICAL FIELD

[0001] The utility model relates to slider processing technical field, in particular to a slider milling chamfer frock clamp. BACKGROUND

[0002] ‌The copper-based self-lubricating slider is a kind of sliding bearing and component made of copper as matrix, and shaped solid lubricant with unique self-lubricating performance is embedded on the metal friction surface of matrix.‌ This kind of slider reduces the friction force or other forms of surface damage between friction surfaces by embedding solid lubricant with low friction coefficient into bearing matrix. The matrix material of copper-based self-lubricating slider is usually high-quality copper alloy, such as copper alloy. The solid lubricant is embedded on the metal friction surface of the matrix to form a shaped solid lubricant with self-lubricating performance. This design makes the metal substrate bear most of the load during friction, and the solid lubricant provides continuous lubrication effect.

[0003] ‌When producing copper-based self-lubricating slider, chamfering treatment is needed. In the prior art, large quantities of slider processing technology is generally through laser cutting or wire cutting equipment. When the raw material copper plate is divided and processed into slider shape, it can be directly cut and formed with chamfer. However, when the order processing quantity received by the manufacturer is small, the cost of directly purchasing laser cutting equipment is high. The solution is to use milling machine processing center to process chamfering for the already processed slider. However, the chamfering has a special angle. If the existing technology simply uses flat-nose pliers to clamp the workpiece, the flat-nose pliers can only clamp one piece of slider at a time because there is no support under the slider when it is stacked, which will cause unevenness. It is difficult to adjust the angle of the slider, and it is also difficult to ensure that the clamping position of the next workpiece is consistent front and back, which will greatly affect the processing efficiency and has further improvement space.
