Abstract
The utility model discloses an inverted scraper which is used for machining transmission case part center holes in a manual operation mode. The inverted scraper comprises a scraper head, a lining and a scraper rod, wherein the scraper head is connected with one end of the scraper rod in a clamped mode, and the lining is arranged at one end, close to the scraper head, of the scraper rod. The scraper rod is mounted on an electric hand drill, machining is carried out through manual operation, machining is flexible and convenient, parts can be clamped quickly, production efficiency is improved, and production cost is lowered.
Description
Technical field
The utility model relates to a kind of machine tools, and concrete is a kind of anti-scraper.
Background technology
When processing small batch transmission case part, to design workpiece processes on radial drilling machine or vertical machining centre, adopt this method processing, then cost is higher if small lot batch manufacture designs workpiece, and production efficiency is lower, therefore be necessary to design a kind of new machining tool, meet the needs of production.
The utility model content
The utility model proposes a kind of anti-scraper, by the mode replacement equipment processing of the anti-scraper of manually-operated processing, process flexiblely, clamping is fast, has improved production efficiency, and has reduced production cost.
The technical solution of the utility model is achieved in that a kind of anti-scraper, be used for manual operations processing transmission case part centre bore, comprise cutter head, lining and knife bar, one end clamping of described cutter head and knife bar, blade is positioned at the side of cutter head near the knife bar center, and lining is located at an end of close cutter head on the knife bar.
Further, described tool bit casing is fixed by screw at knife bar one end.
Further, four blades are arranged on the described cutter head.
Further, described sleeve surface is provided with skid resistant course.
Further, described lining skid resistant course is the annular knurl layer.
The beneficial effects of the utility model are: knife bar is installed on the electric hand drill, process by way of manual operation, flexible, clamping is fast, improved production efficiency, and reduced production cost, and the annular knurl layer of sleeve surface makes sleeve surface frictional force strengthen greatly, and be difficult under normal operating condition, wearing and tearing.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the user mode schematic diagram of the utility model embodiment.
Among the figure: 1, screw; 2, cutter head; 3, lining; 4, knife bar; 5, skid resistant course.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
A kind of anti-scraper as shown in Figure 1 and Figure 2, be used for manual operations processing transmission case part centre bore, comprise cutter head 2, lining 3 and knife bar 4 with four blades, it is fixing by screw 1 that described cutter head 2 is enclosed within knife bar 4 one ends, blade is positioned at the side of cutter head 1 near knife bar 4 centers, lining 3 is located at an end of close cutter head 2 on the knife bar 4, and lining 3 surfaces are provided with skid resistant course 5.In use, knife bar 4 is installed on the electric hand drill, process by way of manual operation, flexible, clamping is fast, has improved production efficiency, and has reduced production cost, and the annular knurl layer on lining 3 surfaces makes lining 3 skin-friction forces strengthen greatly, and is difficult for wearing and tearing under normal operating condition.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
