Abstract
The utility model discloses an automobile mould circular hole chamfering device comprising a tool bit, a cutter bar and a shell, wherein the two ends of the cutter bar are respectively connected with the tool bit and the shell, a sliding sleeve is arranged on the inner side of the shell, the cutter bar is provided with a helical groove body, the helical groove body is matched with the sliding sleeve, and the tail end of the helical groove body is connected with a spring. The automobile mould circular hole chamfering device disclosed by the utility model needs no large cutting force, so that a few of air tools is necessary for preparation, and the automobile mould circular hole chamfering operation can be performed at any time and any place, thereby greatly improving the chamfering efficiency and greatly reducing the cost.
Description
Technical field
The utility model relates to the automobile die field, is specially a kind of automobile die circular hole chamfer device.
Background technology
The corner of automobile die and circular hole all need chamfering, less circular hole chamfering usually adopts drilling machine or uses the air sander instrument, because of the volume of automobile die own larger, cause carrying inconvenient, lengthened the fabrication cycle of mould, and the drilling machine equipment cost is higher, and air sander needs source of the gas to do driving, chamfering efficiency is low again, causes production cost higher.
The utility model content
The technical problem that the utility model solves is to provide a kind of automobile die circular hole chamfer device, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
Automobile die circular hole chamfer device, comprise cutter head, knife bar and housing, the two ends of described knife bar are connecting respectively described cutter head and housing, described housing inboard is provided with sliding sleeve, described knife bar is with the spiral cell body, described spiral cell body and described sliding sleeve are complementary, and the end of described spiral cell body is connected with spring.
In the utility model, an end of described sliding sleeve is connected with steel ball.Described cutter head and knife bar are for being threaded.
Beneficial effect
The utility model does not need too large cutting force, does not therefore need more pneumatic tool to prepare, and can conveniently carry out automobile die circular hole chamfering whenever and wherever possible, so that chamfering efficiency promotes greatly, cost also reduces greatly.
Description of drawings
Fig. 1 is the structural representation of automobile die circular hole chamfer device.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, the structural representation of automobile die circular hole chamfer device, automobile die circular hole chamfer device, comprise cutter head 1, knife bar 2 and housing 4, the two ends of described knife bar 2 are connecting respectively described cutter head 1 and housing 4, and described housing 4 inboards are provided with sliding sleeve 6, and described knife bar 2 is with the spiral cell body, described spiral cell body and described sliding sleeve 6 are complementary, and the end of described spiral cell body is connected with spring 3.
In the utility model, an end of described sliding sleeve 6 is connected with steel ball 5.Described cutter head 1 and knife bar 2 are for being threaded.
Housing of the present utility model can with metal forging or punch forming, also can be used the engineering plastics injection mo(u)lding.During use, hold the handle of housing, push away before the cutter head that links to each other with knife bar being put into the hole reinforcing of workpiece, because cutter head is obstructed, do not do to advance, sliding sleeve and knife bar that cause is fixed on the housing are movingly, under the mating reaction of the spiral cell body on the knife bar and the steel ball on the sliding sleeve, produce compound motion, housing is pushed ahead, and Compress Spring, knife bar rotates.Cutter head passes through the elastic reset of the spring of compression when leaving workpiece.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model; the technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
