Abstract
The utility model discloses a conical angle grinder, comprising an angle grinder column body, wherein an angle grinding groove is arranged above the angle grinder column body and is provided with a grinding surface with a conical inclined surface; and an axial positioning hole is arranged below the angle grinder column body and is used for fixing the angle grinder on a rotating shaft of a motor so as to drive the angle grinder to rotate synchronously by constant speed rotation of the motor. The conical angle grinder disclosed by the utility model has the advantages that since the working surface of the angle grinder is of a conical inclined surface structure, the platform surface of a chip is easily ground into an inclined-plane modeling with certain angle and width, and the damage layer caused by the platform surface of the chip is less; and the use method is simple and easy to learn and the manual operation is convenient.
Description
Technical field
The utility model relates to a kind of manufacturing installation of common electric power rectifier tube chip, specifically a kind of bevelling post.
Background technology
Along with the progress of power device manufacturing technology, the power rectifier pipe is towards large electric current, high-tension future development.In order to improve the operating voltage of device, just must improve simultaneously the high-tension ability of carrying of power rectifier die.
In traditional technical field, the method that usually adopts in the industry is along the conical inclined surface moulding (being referred to as the table top moulding of chip) of grinding out single angle and width one week of chip edge of circle, thereby makes chip have certain breakdown voltage.
Existing angle lap mode all is to adopt manual angle lap mode, namely with hand with chip by being pressed on the bevelling post, bevelling post is done synchronous circular motion by the driven by motor rotation, chip is also done synchronous circular motion simultaneously.The hand-guided chip makes chip edge grind out needed angle and width (the table top moulding of chip).
The utility model content
The technical problems to be solved in the utility model provides a kind of cone mill hornwork of new structure, makes the edge of common electric power rectifier tube chip, is easy to grind out needed conical inclined surface structure (the table top moulding of chip).
The utility model solves the problems of the technologies described above by the following technical solutions: a kind of cone mill hornwork, comprise the bevelling post cylinder, and the top of described bevelling post cylinder offers the angle lap groove, and described angle lap groove has the abradant surface of conical inclined surface.
More optimize, the below of described bevelling post cylinder offers the axial location hole, and synchronous circular motion is not eccentric when guaranteeing the angle lap operation.
The utility model has the advantage of: because the working face of bevelling post is round tapered slope structure, make the edge of semiconductor electric chip grind to form easily needed table top moulding, and the damage layer that brings to chip table is less.The machinery location is effectively simple, and rotating shaft is not eccentric.Method of operating is easy to learn.
Description of drawings
Fig. 1 is the sectional view of the utility model cone mill hornwork.
The specific embodiment
See also shown in Figure 1ly, the utility model cone mill hornwork comprises bevelling post cylinder 1.
The top of described bevelling post cylinder 1 offers angle lap groove 12, and described angle lap groove 12 has the abradant surface 122 of conical inclined surface.
The below of described bevelling post cylinder 1 offers axial location hole (not shown), be used for bevelling post is fixed in the rotating shaft of motor (not shown), thereby after the motor operation, can do together at the uniform velocity circular-rotation by drive bevelling post cylinder 1 and abradant surface 122 wherein.
With hand needs are ground to form on the abradant surface 122 of silicon chip by the taper of the angle lap groove 12 that is pressed in bevelling post of bevel edge, bevelling post is rotated by motor drives, and hand-guided can make the edge grinding of chip go out needed table top moulding.
The above is only for the preferred embodiment of the invention; not in order to limit the invention; all in the invention spirit and principle within do any modification, be equal to and replace and improvement etc., all should be included within the protection domain of the invention.
Claims (2)
1. cone mill hornwork, it is characterized in that: comprise the bevelling post cylinder, the top of described bevelling post cylinder offers the angle lap groove, and described angle lap groove has the abradant surface of conical inclined surface.
