Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1 to 2, a vertical machining center fixture includes a machining plane 1, a base 2, a spring 6, and a hand wheel 10; the vertical bolt 4 that is provided with on base 2, the spring 6 is vertical to be fixed on base 2 and to set up around bolt 4, 6 tops of spring are provided with briquetting 5, briquetting 5 can be by the pulling upward movement under the effect of spring 6, realizes pressing from both sides tight to the work piece, 2 both sides of base are provided with backup pad 8, backup pad 8 is fixed mutually with machining plane 1, hand wheel 10 is connected with backup pad 8 through lead screw 9, and the manual rotation hand wheel 10 of staff makes lead screw 9 remove to product place direction when pivoted, lead screw 9 level set up and cooperate with the cylindrical through-hole position that the work piece upper level set up is corresponding and size, and lead screw 9 runs through cylindrical through-hole, avoids causing the removal of work piece position because slight rotation at the processing work piece in-process.

Base 2 is located machining plane 1, bolt 4 specifically is stud, can make things convenient for the staff to adjust the position of briquetting 5 when the nut on 4 tops of bolt is unscrewed, and after the adjustment was accomplished, the staff screwed up the nut, made briquetting 5 compress tightly the product completely.

The side of the bolt 4 is provided with a positioning pin 7, and the positioning pin 7 corresponds to a vertically arranged rectangular hole in the workpiece in position and is used for preliminarily positioning the workpiece.

The hand wheel 10, the supporting plate 8 and the screw rod 9 are symmetrically arranged about a central line where the length direction of the processing plane 1 is located, the screw rod 9 moves towards the direction of a workpiece under the rotation of the hand wheel 10 until penetrating through a cylindrical through hole in the workpiece, and therefore the workpiece is prevented from rotating in the processing process to cause processing inaccuracy.

2 bottom of base is all around through screw 3 and 1 fixed connection of machined surface, prevents that the skew of base 2 emergence position from influencing the processing of work piece at the in-process of processing work piece.

The pressing block 5 penetrates through the bolt 4 and moves along the straight line where the length direction of the bolt 4 is located, so that the height of the pressing block 5 can be conveniently adjusted according to the height of a workpiece, and the pressing of the inner part of the workpiece is realized.

The working principle is as follows: the worker unscrews the nut above the bolt 4, places the workpiece on the base 2, penetrates through a hole vertically formed in the workpiece through the positioning pin 7, the workpiece to be processed is preliminarily positioned, after the nut on the bolt 4 is unscrewed, the pressing block 5 moves upwards under the action of the spring 6, the pressing block 5 is manually pulled upwards until two sides inside the workpiece can be pressed, then the nut is screwed down to ensure that the workpiece is completely pressed, when the workpiece is processed, the phenomenon of position movement can not occur, the hand wheel 10 is manually rotated to rotate the screw rod 9, and moves along the direction of the workpiece, the screw rods 9 on both sides correspond to the cylindrical through holes on both sides of the workpiece, the cylindrical through hole which can directly rotate and penetrate through the workpiece further prevents the workpiece from rotating to cause the movement of the position in the machining process, ensures the qualification rate of the machined workpiece to be machined, and improves the workpiece machining efficiency.
