Abstract
The utility model relates to an assembly fixture for an A-station die head and a B-station die head, in particular to a tool fixture for maintaining, assembling and disassembling an upper die for a numerical control punch. The invention provides an assembly fixture used for an A-station die head and a B-station die head and being capable of overcoming the degree of free rotation by using positioning keys for an A-station upper die and a B-station upper die and performing clamping in a surface contact manner so as to avoid the outer surfaces from being damaged. The assembly fixture comprise fixed seats, a movable seat hinged with the fixed seats and a locking device, wherein, semi-circular arcs are respectively formed on the fixed seats and the movable seat, a circular contour formed when the fixed seats and the movable seat are collected is slightly smaller than that of an outer circle of the B-station die head and a groove for accommodating a positioning key for the B-station die head is formed on one semi-circular arc of the two semi-circular arcs. The utility model realizes the clamping of the surface contact by clamping the cylindrical die by using a pair of the fixed seats with cambered surfaces and the movable seat and effectively avoids the damage of the outer surfaces of the die; and the utility model is good in use effect, avoids the dies from being damaged during the maintenance, is high in adaptability and can be adapted to two different kinds of dies.
Description
Technical field
The utility model relates to the frock clamp of a kind of maintenance, assembling, dismounting numerical control press patrix, relates in particular to a kind of assembling jig that can be applicable to die head on A on the NC turret punch machine, the B station simultaneously.
Background technology
The capstan head of NC turret punch machine is provided with the mould station of A, B, C, four kinds of different installation forms of D.Along with popularizing of NC turret punch machine, the mould of above-mentioned several stations has progressively become the standard component in the industry.In long-term use, wearing and tearing, damage can appear in the drift of patrix, and perhaps faults such as distortion appear in guide rod, and the cost of replacing is very high.The unit that much has maintainability takes the maintenance means, repairs the patrix that breaks down.During maintenance, the upper die component clamping need be disassembled again, fault part is wherein repaired.Now, generally adopt bench vice that upper die component is carried out clamping during reparation, the jaw hardness of bench vice is big, rubbing surface is arranged, and contacts with line between the upper die component, and damages the outer surface of upper die component easily.The requirement that has quality of fit between the die sleeve of upper die component outer surface and numerical control stamping machine tool after the employing said method is repaired the patrix internal fault, outer damage can occur again.
The utility model content
The utility model provides a kind of A of utilization, B station patrix self poisoning key to overcome its rotary freedom at above problem, and by face contact clamping, thereby can avoid damaging the A of its outer surface, the assembling jig of B station die.
The technical solution of the utility model is: comprise holder, with hinged sliding seat, the locking device of holder, be respectively equipped with semi arch on holder and the sliding seat, the circular contour that constitutes when holder and sliding seat close is slightly less than the excircle configuration of B station die, and a semi arch is provided with the groove that holds B station die positioning key therein.
It also comprises the B-A conversion sleeve, the cylindrical of described conversion sleeve is consistent with the excircle configuration of B station die, the diameter of bore of described conversion sleeve is slightly larger than the excircle configuration of A station die, offer the seam that runs through whole conversion sleeve height on the jacket wall of described conversion sleeve, the width of described seam is greater than the gap sum of the cylindrical of the endoporus of the width of A station die positioning key, conversion sleeve and A station die.
The utility model utilizes a pair of holder and sliding seat with cambered surface that the cylindricity mould is carried out clamping, has realized the clamping of face contact, has effectively avoided the damage to mold outer surface; Also adopt the scheme of coaxial cooperation conversion, utilized conversion sleeve to realize adjusting, realized that anchor clamps can adapt to the clamping of two kinds mould, made the clamping that anchor clamps can adaptive two kinds of moulds.For example, in the utility model, when not adopting conversion sleeve, can be directly applied for the patrix of B station, increase the B-A conversion sleeve, A station one cover Standard Module is put into conversion sleeve, reinstall in " hole " of a pair of circular arc formation, realize clamping A station mould.The utility model result of use is good, avoided in the maintenance damage to mould, and adaptability is strong, can adapt to two kinds of different moulds.
