Abstract
The utility model relates to a disc type part chuck base, which belongs to the field of machine tool parts. The existing disc type part chuck base has the defects of high processing difficulty and high processing equipment requirement. The utility model is characterized in that the bottom and the side wall form into a circular barrel shape, a projected circular table body is arranged in the center position of the outer surface of the bottom, the top surface of the circular table body is vertical to the center line of the base, the outer surface of the bottom is parallel to the top surface of the circular table body, the top surface of the side wall is parallel to the top surface of the circular table body, and the outer surface of the side wall is vertical to the top surface of the circular table body. Through installing the circular table body in the center of the outer surface of the bottom of the base and using the top surface of the circular table body as a reference surface, the utility model reduces the area of the plane to be processed, so the planeness of the plane can be easily ensured, and the processing difficulty is lowered.
Description
Technical field
The utility model belongs to the machine tool element field, and is especially relevant with a kind of disk-like accessory chuck base.
Background technology
Oild chuck generally comprises base, claw and transmission mechanism, and transmission mechanism is connected with claw, and is connected with hydraulic cylinder piston by connecting rod, and the transmission mechanism transmission that moves through of oil cylinder piston provides power for the contraction and the expansion of claw; Base is round barrel shape, constitutes semiclosed hollow cavity by bottom surface and sidewall, and transmission mechanism is positioned at this inner chamber.When chuck is installed, with the base rear end face as the datum level that engages with main shaft, require accurate flatness, and with the perpendicularity of base periphery, because the diameter of disk-like accessory chuck is bigger, the rear end face diameter of base is also just bigger, and the base rear end face adds the large diameter emery wheel grinding machine of needs in man-hour, make that base rear end face difficulty of processing is big, the process equipment requirement is high, cost is high.
The utility model content
The purpose of this utility model is exactly to overcome big, the demanding defective of process equipment of difficulty of processing that existing disk-like accessory chuck base exists, a kind of disk-like accessory chuck base of simple in structure, handling ease is provided, for this reason, the utility model is by the following technical solutions:
Disk-like accessory chuck base, constitute round barrel shape by bottom and sidewall, it is characterized in that: described bottom outer surface centre is provided with the Rotary-table of protrusion, the Rotary-table end face is perpendicular to the base center line, bottom outer surface is parallel with the Rotary-table end face, the end face of described sidewall is parallel with the Rotary-table end face, and the outer surface of sidewall is vertical with the Rotary-table end face.
When chuck uses, described Rotary-table end face is as the location datum level is installed, also be that the composition surface is installed, because bottom outer surface is parallel with the Rotary-table end face, as long as calibrate bottom outer surface, just can make base reach requirement during installation with the installation accuracy that engages of main shaft to the installation accuracy that requires, because the end face of base side wall is parallel with the Rotary-table end face, the Rotary-table end face is perpendicular to the base center line, and the outer surface of sidewall is vertical with the Rotary-table end face, and the installation accuracy of chuck also just reaches requirement so.
Use the utility model can reach following beneficial effect: by Rotary-table being set, as datum level, need to reduce the area of processing plane, the flatness on plane is guaranteed easily, reduced difficulty of processing with the Rotary-table end face at base bottom outer surface center.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the partial enlarged drawing at a place among Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in detail.
As Fig. 1～shown in Figure 3, the utility model constitutes round barrel shape by bottom 1 and sidewall 4, the centre of bottom outer surface 2 is provided with the Rotary-table of protrusion, Rotary-table end face 3 is perpendicular to the center line of base, bottom outer surface 2 is parallel with Rotary-table end face 3, the end face of sidewall 4 is parallel with Rotary-table end face 3, and the outer surface of sidewall 4 is vertical with Rotary-table end face 3.
When chuck uses, Rotary-table end face 3 is as the location datum level is installed, also be that the composition surface is installed, because bottom outer surface 2 is parallel with Rotary-table end face 3, as long as calibrate bottom outer surface 2, just can make base reach requirement during installation with the installation accuracy that engages of main shaft to the installation accuracy that requires, because the end face of base side wall 4 is parallel with Rotary-table end face 3, Rotary-table end face 3 is perpendicular to the base center line, and the outer surface of sidewall 4 is vertical with Rotary-table end face 3, and the installation accuracy of chuck also just reaches requirement so.
