Description
Technical Field
The invention relates to a pre-righting device for turning a columnar workpiece.
Background
Before the columnar workpiece is machined on a lathe, the columnar workpiece needs to be matched with an ejector pin of the lathe to play a role in aligning, and as the end face of the columnar workpiece is basically a flat end face, before the columnar workpiece needs to be aligned with the ejector pin of the lathe, an aligning groove needs to be turned on the end face of the columnar workpiece through the lathe, then the columnar workpiece is disassembled and assembled again, and the aligning groove on the columnar workpiece is used for positioning with a chuck of the lathe to complete subsequent turning of the columnar workpiece.
Disclosure of Invention
The invention aims to solve the technical problem of providing a pre-righting device for turning of a columnar workpiece, which has a reasonable structure and is convenient to use.
In order to solve the technical problem, the invention provides a pre-righting device for turning a columnar workpiece;
the drilling machine is provided with a workbench, and a positioning hole for placing a columnar workpiece is formed in the center of the positioning seat;
the positioning seat is fixed on a workbench of a drilling machine through a clamping assembly, the clamping assembly comprises a clamping screw, a clamping nut, a clamping plate and a cushion block, the cushion block is placed on the workbench, the lower end of the clamping screw is fixedly connected onto the workbench, the screw portion of the clamping screw penetrates through the clamping plate to be matched with the clamping nut, and two ends of the clamping plate are respectively supported on the upper end face of the cushion block and the upper end face of the workbench.
After the structure is adopted, the positioning seat is fixed on the workbench of the drilling machine by utilizing the clamping assembly, the columnar workpiece is placed in the positioning hole of the positioning seat, and the drilling machine drills a normal position groove on the end face of the columnar workpiece, so that the subsequent lathe is convenient to position.
For a clearer understanding of the technical content of the present invention, the turning pre-alignment device for cylindrical workpieces is simply referred to as the pre-alignment device below.
The clamping screw of the pre-righting device comprises a clamping screw head and a clamping screw rod, wherein the side wall of a workbench of a drilling machine is provided with at least one positioning groove for the clamping screw to reciprocate, the positioning groove comprises a first-stage groove at the upper side and a second-stage groove at the lower side, the cross section of the second-stage groove is matched with the head contour of the clamping screw, the cross section of the first-stage groove is matched with the screw rod contour of the clamping screw, the first-stage groove extends to the upper end face of the workbench, and the clamping screw is matched with the positioning groove of the workbench.
After the structure is adopted, the clamping screw rod can move flexibly along the trend of the positioning groove, and the positioning groove can be matched with the fixed clamping screw rod for fixing.
The positioning seat of the pre-righting device is a three-jaw chuck; the three-jaw chuck is a mature product, has a reliable structure and is easy to obtain.

Fig. 2 is a left side view of fig. 1.
FIG. 3 is a perspective view of a clamping assembly of an embodiment of the pre-righting device.
Detailed Description
As shown in fig. 1 to 3
This righting device in advance includes drilling machine 1, positioning seat 2 and two sets of clamping components.
Drilling machine 1 is commercially available radial drill 1, and drilling machine 1 is equipped with workstation 11, and positioning seat 2 is three-jaw chuck, constitutes the locating hole 21 of placing cylindrical work piece 4 between the three jack catch of positioning seat 2.
The clamping assembly comprises a clamping screw 31, a clamping nut 32, a clamping plate 33 and a cushion block 34, the positioning seat 2 is fixed on the workbench 11 of the drilling machine 1 through the clamping assembly, the cushion block 34 is placed on the workbench 11, the clamping screw 31 comprises a clamping screw head 31b and a clamping screw rod 31a, the side wall of the workbench 11 of the drilling machine 1 is provided with two positioning grooves 11a for the clamping screw 31 to reciprocate, the positioning grooves 11a comprise a first-stage groove 11a1 at the upper side and a second-stage groove 11a2 at the lower side, the cross section shape of the second-stage groove 11a2 is matched with the contour of the head 31b of the clamping screw 31, the cross section shape of the first-stage groove 11a1 is matched with the contour of the screw portion 31a of the clamping screw 31, the first-stage groove 11a1 extends to the upper end face of the workbench 11, the clamping screw 31 is matched with the positioning groove 11a of the workbench 11, so that the lower, the upper end of the screw portion 31a of the clamping screw 31 penetrates through the clamping plate 33 and is engaged with the clamping nut 32, both ends of the clamping plate 33 respectively bear on the upper end surface of the spacer 34 and the upper end surface of the table 11, and the screw portion 31a of the clamping screw 31 is located between the table 11 and the spacer 34.
Before use, the positioning seat 2 is fixed on a workbench 11 of the drilling machine 1 by using a clamping assembly, and the columnar workpiece 4 is placed in a positioning hole 21 of the positioning seat 2; during the use, start drilling machine 1, drilling machine 1's drill bit drills out a normal position groove on 4 terminal surfaces of cylindrical work piece, repeats above-mentioned operation and carries out normal position groove continuous processing to a plurality of cylindrical work pieces 4, makes things convenient for follow-up lathe location.
The above description is only one embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the principle of the present invention, and these should also be considered as falling within the protection scope of the present invention.
