Abstract
The utility model discloses a semiconductor crystal bar grinding is with universal loose top, its structure includes interconnect's top body and top bowl, still be equipped with the top piece between the top body and the top bowl, top body one end is equipped with 3 tailstock connection screws, the other end is connected in top bowl one end, the top piece is located between the top body other end and the adjacent department of top bowl, top bowl one end side is fixed with top body other end through 2 interior hexagonal screws that the position is relative, interior hexagonal screw passes the screw on top bowl one end side and twists in the top body other end corresponds the position screw. The utility model has the advantages that: structural design is reasonable, and top adjustable position is pressed from both sides after the initial installation, beats crystal excircle with the silk table, if beat too big, and adjustable is carried out to the adjustable top of accessible. The top bowl and the top head body are matched and ground, so that a contact surface is increased, the clamping is firmer, and the grinding precision can be well ensured when the grinding amount and the grinding force are larger.
Description
Technical Field
The utility model relates to a semiconductor crystal bar grinding is with universal loose top belongs to grinding machine technical field.
Background
In the traditional cylindrical grinding machine in the prior art, the head and tail frames are in a top-type structure, if a semiconductor crystal material needs to be ground by the cylindrical grinding machine, two nylon switching round bars are fixed on two end faces of a crystal bar in a viscose mode, and a central hole is formed in the nylon switching round bars, so that clamping is realized.
In the above mode of the prior art, the viscose is not environment-friendly, wastes time and labor, and still needs to come unstuck after the grinding is completed, which is very tedious and affects the production efficiency.
SUMMERY OF THE UTILITY MODEL
The utility model provides a semiconductor crystal bar grinding is with universal loose top, its purpose aims at overcoming the above-mentioned not enough that prior art exists, has changed the top structure of prior art to the mode of both ends plane top carries out the clamping, and designs into the convenient adjustment of loose top that can universal regulation, and top piece and top head body cylinder part match the mill, can improve grinding precision.
The technical solution of the utility model: the structure of the universal adjustable top for grinding the semiconductor crystal bar comprises a top head body and a top bowl which are connected with each other, a top plate is further arranged between the top head body and the top bowl, one end of the top head body is provided with 3 tail frame connecting screw holes, the other end of the top head body is connected into one end of the top bowl, the top plate is located between the other end of the top head body and the adjacent position of the top bowl, one side surface of one end of the top bowl is fixed with the other end of the top head body through 2 inner hexagon screws with opposite positions, and the inner hexagon screws penetrate through the screw holes in one side surface of one end of the top bowl and are screwed into the screw holes in the corresponding positions of the other end of the top head body.
Preferably, the other end of the top head body is an outer convex spherical surface, and the surface of the top sheet contacting with the other end of the top head body is an inner spherical surface matched with the shape.
Preferably, an adjusting gap is reserved between the side face of the other end of the ejector head body, which is positioned in one end of the ejection bowl, and the ejection head body and the ejection bowl are fixed by the inner hexagonal screw without locking.
The utility model has the advantages that: structural design is reasonable, and top adjustable position is pressed from both sides after the initial installation, beats crystal excircle with the silk table, if beat too big, and adjustable is carried out to the adjustable top of accessible. The top bowl and the top head body are matched and ground, so that a contact surface is increased, the clamping is firmer, and the grinding precision can be well ensured when the grinding amount and the grinding force are larger.

Detailed Description
The present invention will be described in further detail with reference to examples and embodiments.
As shown in fig. 1 and 2, the universal adjustable top for grinding semiconductor crystal bars structurally comprises a top body 1 and a top bowl 2 which are connected with each other, a top plate 3 is further arranged between the top body 1 and the top bowl 2, 3 tail frame connecting screw holes are formed in one end of the top body 1, the other end of the top body is connected into one end of the top bowl 2, the top plate 3 is located between the other end of the top body 1 and the adjacent position of the top bowl 2, one end side face of the top bowl 2 is fixed with the other end of the top body 1 through 2 inner hexagon screws in opposite positions, and the inner hexagon screws penetrate through screw holes in one end side face of the top bowl 2 and are screwed into screw holes in corresponding positions of the other end of the top body 1.
The other end of the top head body 1 is an outer convex spherical surface, and the surface of the top sheet 3 contacting the other end of the top head body 1 is an inner spherical surface matched with (ground) in shape. The contact surface can be increased.
An adjusting gap is reserved between the side face of the other end of the top head body 1, which is positioned in one end of the top bowl 2, and the top head body 1 and the top bowl 2 are fixed by the inner hexagonal screw but are not locked. The part can be adjusted in a universal movement mode when being clamped.
According to the structure, the top bowl 2 with different dimensions can be matched according to different part specifications (outer diameter dimensions), when the top bowl is used, the top head body 1 is fixed on the head and tail frame component through 3 inner hexagon screws, the top plate 3 is placed into the top bowl 2, and finally the top bowl 2 and the top plate 3 are fixed on the top head body 1 through two inner hexagon screws with longer lengths.
All the above components are prior art, and those skilled in the art can use any model and existing design that can implement their corresponding functions.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the inventive concept, and all of them belong to the protection scope of the present invention.
