Description
Technical Field
The utility model relates to a polycrystalline diamond excircle anchor clamps belongs to diamond production processing equipment technical field.
Background
Polycrystalline diamond compacts, also commonly referred to as polycrystalline diamond in the industry for short, are generally formed by sintering polycrystalline diamond micro powder and alloy at high temperature, and one commonly used structure is disc-shaped; before the composite sheet with the shape is put on the market, the outer circle of the composite sheet needs to be processed to make the specification of the composite sheet uniform. The conventional cylindrical clamp can only be processed singly, and if a plurality of cylindrical clamps are processed together, the cylindrical clamps are not easy to place and are easy to stagger during clamping, so that defective products appear in processed products; or need many people to cooperate and place, extravagant labour, increase cost, consequently need a anchor clamps that is fit for a plurality of discoid compound pieces and carries out excircle processing together.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects, the utility model provides a polycrystalline diamond excircle anchor clamps of a plurality of compound pieces of centre gripping simultaneously rational in infrastructure.
In order to realize the purpose, the technical scheme of the utility model is that: a polycrystalline diamond cylindrical clamp comprises a long strip-shaped base, wherein two opposite vertical plates are vertically arranged on one side of the base, and a handle is arranged on the other side of the base; the two vertical plates are respectively provided with a threaded through hole, the two threaded through holes are oppositely arranged, the two threaded through holes are respectively provided with a matched puller bolt which is arranged from the outer side to the inner side, and the end surface of the screw rod end of the puller bolt is a smooth plane; a through hole in the vertical direction is formed in the center of the base between the two vertical plates, a damping ring is nested in the through hole, and a top rod is arranged from the lower portion of the base, penetrates through the damping ring and is matched with the damping ring; the top of the ejector rod is connected with a tray matched with the outer diameter of the polycrystalline diamond compact, the inner contour of the longitudinal section of the tray is in a minor arc shape, and the width of the tray is at least equal to the thickness of 10 stacked polycrystalline diamond compacts; the center of the bottom of the tray is detachably connected with the top of the ejector rod through threads.
Preferably, the ejector rod body is provided with scales which are mainly used for quantifying the pushing height of the ejector rod.
The beneficial effect of this application does: 1. the jacking bolt with a smooth end face is adopted for clamping, the structure is rigid clamping, and the problem of error caused by torsion generated in grinding wheel machining when the existing clamping structure with the spring is used for clamping is solved; 2, a minor arc-shaped tray with adjustable height is arranged, a plurality of workpieces can be placed on the tray, and then clamping operation is carried out, so that on one hand, the clamping position of the workpieces is easy to ensure, and on the other hand, single-person operation can be realized, labor is saved, and efficiency is improved; 3, the rod body of the ejector rod is provided with scales, so that the height requirements of workpieces with different specifications and sizes can be met, and the matching structure of the ejector rod and the damping ring is convenient to adjust; 4, simple structure, with low costs, the uniformity is good when drawing the excircle, the dress is many, error range is little, personnel's operational safety improves, easy operation.
