Description

Radiator aluminium alloy dotting device

Technical Field

The utility model relates to an aluminum plate technical field that punches, especially a device is got ready to radiator aluminium alloy.

Background

Need punch in the aluminum plate in the radiator, consider the radiating efficiency, need drill out sufficient hole on aluminum plate, utilize these holes to make aluminum plate can fully play the effect of heat transfer, need not drill through aluminum plate under the sufficient thick condition of aluminum plate, only need in the downthehole screw thread that reams that drills out can, if drill through, not only need the deburring, but also can influence the installation accuracy, influence the level and smooth of opposite side surface. The special machine tool is arranged in a production workshop, the drilling depth can be controlled, the position precision of the reserved hole can be guaranteed, on the installation site, deviation of some reserved hole positions always occurs due to error accumulation, manual on-site drilling is needed at the moment, the aluminum plate is easily drilled through by manual drilling, or the situation that the drilled hole is not perpendicular to the surface occurs, burrs are removed later, the overall quality of a product is affected, if the requirement of a customer is met, the drilled hole part can be completely filled with the metal repairing agent, and the trouble is not brought to an installer.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned condition, for overcoming prior art's defect, the utility model provides a device is got ready to radiator aluminium alloy, among the effectual prior art that has solved, aluminum plate gets ready and gets the problem of the inconvenient control of drilling in-process hole depth.

The technical scheme includes that the device comprises a horizontal annular sleeve, a plurality of threaded holes formed in the side wall of the annular sleeve along the radial direction of the annular sleeve are formed in the side wall of the annular sleeve, the threaded holes are circumferentially and uniformly distributed, compression screws are arranged in the threaded holes, a vertical fixed cylinder is fixed to the lower section of the annular sleeve, threads are formed in the outer circular surface of the fixed cylinder, an annular plate is connected to the fixed cylinder through threads, a movable cylinder is sleeved at the lower end of the fixed cylinder, the movable cylinder is in clearance fit with the fixed cylinder, the movable cylinder can move up and down along the fixed cylinder, a plurality of vertical rods are fixed to the lower end of the annular plate, and the; a plurality of pressure springs are arranged between the lower end of the annular plate and the upper end of the movable cylinder.

The utility model discloses the structure is ingenious, and the effectual aluminum plate of having avoided is worn, and effective control drilling depth guarantees site operation quality, reduces the trouble in the installation.

Detailed Description

The following detailed description of embodiments of the present invention is made with reference to the accompanying drawings.

As shown in fig. 1 to 4, the utility model discloses a horizontal annular sleeve 1, there are a plurality of screw holes along its radial setups on the annular sleeve 1 lateral wall, a plurality of screw holes are the circumference equipartition, there is compression screw 2 in the screw hole, the annular sleeve 1 hypomere is fixed with vertical solid fixed cylinder 3, there is screw thread on the outer disc of solid fixed cylinder 3, there is annular plate 4 on the solid fixed cylinder 3 through threaded connection, the solid fixed cylinder 3 lower extreme cover is equipped with movable cylinder 5, clearance fit between movable cylinder 5 and the solid fixed cylinder 3, movable cylinder 5 can reciprocate along solid fixed cylinder 3, the lower extreme of annular plate 4 is fixed with a plurality of vertical montants 6, montant 6 is in the movable cylinder 5 outside; a plurality of pressure springs are arranged between the lower end of the annular plate 4 and the upper end of the movable cylinder 5.

In order to reduce the whole volume, the upper end of the fixed cylinder 3 is in a horn shape with an upward opening.

In order to facilitate the observation of the punching position, the movable cylinder 5 is hollowed out.

It should be noted that, in order to better limit the depth of the drilled hole and to ensure the verticality of the drilled hole as much as possible, the lower end of the movable cylinder 5 is provided with an annular protrusion.

During the use, arrange the rig head in annular cover 1, revolve to twist housing screw 2 and make annular cover 1 firmly fix at the rig head, make the annular of 5 lower extremes of movable cylinder laminate with aluminum plate on predetermined position this moment, start the rig, and press down, the drill bit takes annular cover 1 to move down, drill bit contact aluminum plate and drill out the hole, until 6 lower extremes of montant and the annular protruding contact of 3 lower extremes of solid fixed cylinder, the rig can not move down again, the drill bit idle running, then lift up the drill bit, drilling is accomplished.

In the above process, the lowest end of the movable cylinder 5 is lower than the lowest end of the drill bit, and when the lower end of the vertical rod 6 is contacted with the annular bulge, the part of the drill bit, which protrudes out of the lower end of the movable cylinder 5, is the drilling depth. If the hole depth needs to be adjusted, the annular plate 4 only needs to be screwed, so that the annular plate 4 moves up and down along the fixed cylinder 3, and the adjustment of the drilling depth is realized.
