Abstract
The utility model provides a clamping tooling for a laser cut hole of a small-diameter thin-wall tube, aiming at solving the problem that a workpiece easily has the plastic deformation in the existing clamping tooling for a laser cut hole of a small-diameter thin-wall tube. The tooling comprises a chuck and a tip respectively arranged at two ends of the small-diameter thin-wall tube, the improved tooling further comprises a support central spindle, the support central spindle is a three-section structure, which is sleeved in the small-diameter thin-wall tube, the middle section of the support central spindle is a part which is matched with the small-diameter thin-wall tube, and the outer diameter d of the middle section is 0.2mm less than the inner diameter of the small-diameter thin-wall tube. The clamping tooling is additionally provided with the thin-wall tube support central spindle on the basis of the existing tooling, and the central spindle is sleeved in the hole of the small-diameter thin-wall tube, to support the small-diameter thin-wall tube, so that the plastic deformation can be effectively avoided on the basis that the small-diameter thin-wall tube is clamped; and the support central spindle can further screen the high temperature generated by the laser cut hole, so that the pipe wall at the other side of the diameter of the cut hole can not be burnt.
Description
Technical field
The utility model relates to a kind of frock, cuts the clamping tooling in hole especially for minor diameter thin wall pipe laser.
Background technology
A kind of minor diameter thin wall metal tube; Need to carry out laser and cut hole processing at tube wall; Its course of work is following: adopt scroll chuck that the one end location of pipe is clamped; To workbench, workbench utilizes pneumatic means to run to the operating position to the other end with the top clamping that holds out against, and drives laser cutting head cutting processing on tube wall by robot and goes out circular hole and slotted hole.This routine adds holds frock and have two problems: 1. scroll chuck can cause the severe plastic deformation of pipe on diametric(al) when clamping light-wall pipe, makes the pipe locate failure; 2. utilize laser on the tube wall of minor diameter thin wall pipe, to cut the hole, the high temperature that laser produces can cause the burn to the opposite side tube wall when this side pipe of completion wall cuts the hole.
The utility model content
The utility model is used to overcome the defective of prior art and provides a kind of minor diameter thin wall pipe laser of light-wall pipe plastic deformation of can effectively avoiding to cut the hole clamping tooling.
The alleged problem of the utility model is that following technical scheme solves:
A kind of minor diameter thin wall pipe laser cuts the hole clamping tooling; It comprises the chuck that is positioned at minor diameter thin wall pipe two ends and top; Special feature is: said frock also comprises support mandrel, and support mandrel is a three-stage structure, and it is sleeved in the minor diameter thin wall pipe; Its stage casing is and minor diameter thin wall pipe matching part that the stage casing outside diameter d is littler 0.2 millimeter than minor diameter thin wall bore.
Above-mentioned minor diameter thin wall pipe laser cuts the hole clamping tooling, and said support mandrel left side section diameter d 1 is littler 0.5 millimeter than minor diameter thin wall external diameter of pipe.
Above-mentioned minor diameter thin wall pipe laser cuts the hole clamping tooling, and said support mandrel stage casing diameter is greater than right section diameter, and right segment length L extends the scope of position, cut hole on the minor diameter thin wall pipe.
The utility model cuts the hole clamping tooling to existing minor diameter thin wall pipe laser and is prone to the problem of workpiece generation plastic deformation is improved; On the basis of original frock, set up the light-wall pipe support mandrel; This core sleeve is contained in the hole of thin minor diameter wall pipe; It is played a supporting role, guaranteeing effectively to prevent plastic deformation on the tight basis of minor diameter thin wall pipe clamp; In addition, support mandrel can also be cut the high temperature generation shielding action that the hole produces to laser, and protection is cut bore dia opposite side tube wall and do not burnt.The utility model is simple in structure, realizes easily, and is simple and quick to the workpiece mount.
Description of drawings
Fig. 1 is the utility model structural representation.
Label is represented as follows in the accompanying drawing: 1. chuck; 2. support mandrel; 2-1. left side section; 2-2. stage casing; 2-3. right section; 3. minor diameter thin wall pipe; 4. top; 5. position, cut hole.
The specific embodiment
Referring to Fig. 1; The utility model constitutes and to comprise that the chuck 1 that is positioned at minor diameter thin wall pipe 3 two ends with top 4, produces radial plastic deformation for preventing the minor diameter thin wall pipe in clamping process, and the utility model has been set up support mandrel 2; Support mandrel is a three-stage structure; It is sleeved in the minor diameter thin wall pipe 3, and stage casing 2-2 is and the light-wall pipe matching part that the stage casing outside diameter d is littler 0.2 millimeter than light-wall pipe internal diameter.The diameter d 1 of support mandrel left side section 2-1 is littler 0.5 millimeter than minor diameter thin wall external diameter of pipe.Said structure when chuck 1 when clamping the minor diameter thin wall pipe, locating surface is fitted and is located in the left side of support mandrel 2 and the chuck; Play a supporting role to the minor diameter thin wall pipe in the stage casing of support mandrel, the matched in clearance of 0.2mm both can reach the radial location effect, can guarantee the operation that conveniently is installed in the production process again; The left side section of support mandrel and the diameter difference of minor diameter thin wall external diameter of pipe 0.5mm prevent excessively to clamp the plastic deformation that causes the minor diameter thin wall pipe again when guaranteeing the scroll chuck clamping tube.
Still referring to Fig. 1, the right section of support mandrel 2-3 diameter is less, and this segment length L extends the scope of position, cut hole 5 on the minor diameter thin wall pipe, and its effect is to carry out laser when cutting the hole in minor diameter thin wall pipe one side, prevents high temperature burn opposite tube wall.
