The utility model relates to a many drilling frock especially is used for many drilling frock that the bearing frame was inserted.
Background
As shown in fig. 1 and 2, the bearing seat insert used on the automobile engine has a complex shape, the middle part of the bearing seat insert is provided with two through holes 21, the middle part of one side of the bearing seat insert is provided with a semicircular groove 22, the middle part of the other side of the bearing seat insert is provided with an irregular clamping groove 23, and two ends of the bearing seat insert are provided with four irregular supporting columns 24 and mounting holes 25 to be processed; at present, when the mounting holes 25 are machined, four mounting holes can only be machined in batches due to the fact that the tool is difficult to center and position, and machining efficiency is low.
Disclosure of Invention
The utility model aims at the above-mentioned not enough of prior art, provide a bearing frame and insert many drilling frocks, it can realize the branch of work piece well location, and the location is accurate, but all mounting holes of disposable processing, machining efficiency is high.
In order to achieve the purpose, the bearing seat insert multi-position drilling tool comprises a connecting plate, two supporting plates fixedly arranged on the connecting plate and a base plate positioned between the two supporting plates; is characterized in that: wherein a support plate is internally and fixedly provided with a bush with a stepped hole, a positioning rod passes through the bush in a sliding manner, one end of the positioning rod outside the bush is connected with a positioning nut and a backstop nut through threads, the other end of the positioning rod outside the bush is fixedly connected with a conical head, a return spring is sleeved outside the positioning rod inside the stepped hole, and guide bushes on two sides of the bush are arranged in the support plate; a screw bush is arranged in the other supporting plate, a compression screw is connected with the screw bush, and guide bushes are arranged on two sides of the screw bush in the supporting plate; the two supporting plates are connected through a top plate, and a longitudinal cylinder is fixedly arranged in the middle of the top plate.
When the centering device is used, the semicircular groove of the workpiece is aligned to the conical head, the two supporting columns at one end are tightly attached to the inner side surface of one supporting plate, the conical head can realize automatic centering, the workpiece is tightly propped against the other side through the compression screw, the piston rod of the longitudinal cylinder extends out to compress the workpiece, and the positioning is accurate; all drill rods can simultaneously drill holes after penetrating through all the guide bushings, all the mounting holes are machined at one time, and the machining efficiency is high;
as a further improvement of the utility model, the inner side surfaces of the supporting plates at the two sides of the conical head are all connected with positioning blocks; the device can be suitable for workpieces with different widths;
as a further improvement of the utility model, an upper backing plate is fixedly arranged on the backing plate; the device can be suitable for workpieces with different heights, and the application range is enlarged;
to sum up, the utility model discloses can realize that the branch of work piece is well fixed a position, and the location is accurate, can once only process all mounting holes, machining efficiency is high.
