Description
Technical field
The utility model is related to the field that thin-walled revolution workpiece small workpiece drills on cylinder, passes through mandrel, tail plunger tip axle, bullet
Spring, fixed bushing plate, drill bushing, cam etc. realize that thin-walled turns round the requirement of small workpiece fast positioning clamping drill precise holes.
Background technology
Drilling is a kind of conventional processing method in machining, and machine adds sometimes will be on small thin walled cylinder body cylinder in field
Drilling, workpiece 4 as shown in Figure 1 is two ends blind hole, and one end is thin walled cylinder body, and other end outer wall is the screw thread processed, be from
Periphery processing typically uses three-jaw or vice folder clamping of workpieces, borehole accuracy perpendicular to the hole 41 of axis, common drilling
Not high, processing efficiency is low, and workpiece is easily crushed, deformed in clamping process, it is impossible to realize the requirement produced in enormous quantities.
The content of the invention
The purpose of this utility model, which is to provide, a kind of can improve drilling quality, the suitable small thin-walled suitable for batch production
The fixture of sleeve drilling.
The technical scheme that the utility model is used is a kind of fixture for being adapted to small thin walled cylinder body drilling, and it is characterized by it
It is made up of bottom plate, position portion, clamping part, T-slot, fixing hole is designed with bottom plate；Position portion includes supporting plate and solid
Fixed mandrel, fixed bushing plate, drill bushing on the supporting plate, fixed bushing plate is fixed on above supporting plate, filled on fixed bushing plate
There is drill bushing, the center line of drill bushing is overlapped with center line hole to be drilled, and supporting plate is fixed on bottom plate by fixture；Clamping part
Including tailstock-carrier, tail plunger tip axle, spring, fixed plate, cushion block, cam, tail plunger tip axle passes through and is fixed on tailstock-carrier inner chamber
Spring and fixed plate are connected with cushion block, and fixed plate one end is fixed with tailstock-carrier, and the other end is provided with the groove with cam engagement, cam
It is connected by bearing pin with cushion block, tail plunger tip axle, the swing of cam is converted into tail plunger tip axle moves forward and backward.
The utility model bottom plate 2 is fixed on drilling machine by T-slot with fixture, and the Kong Douyong mandrels at two ends are determined
Position, clamping the displacement that is produced by cam rotation reducing moves forward and backward tail plunger tip axle so that clamp or unclamp tail plunger tip axle and
The cooperation of workpiece, handling are quick, and the position of drill bushing determines the position of drilling, and drill bit is guided by the drill bushing on fixed bushing plate
Drilling, it is ensured that the precision of drilling, so as to realize the production in enormous quantities of thin-walled revolution workpiece small workpiece drilling.
The top of tail plunger tip axle is the conical surface, and surface is formed with anti-slip veins.Anti-slip veins can effectively prevent tail plunger tip axle and workpiece it
Between mutual motion.
The utility model is fixed on drilling machine by designed fixture, adjusts good position, and work-handling is quick, by solid
Determine the drill bushing guiding bit bore on bushing plate, effectively solve the requirement drilled on small thin walled cylinder body cylinder, both improved processing
Efficiency, ensures the precision of drilling again, so as to realize that the high-volume of thin-walled revolution workpiece small workpiece drilling is quickly produced.
