Description
Technical Field
The invention relates to a positioner, in particular to an adjustable movable hole positioner, and belongs to the technical field of airplane assembly and processing.
Background
At present, for a hole with a smaller diameter, the precision of the hole diameter is high, the hole is generally positioned by a positioning pin, but for a hole with a larger diameter, such as a flanging hole on a sheet metal part, the precision of the hole diameter is low, but the requirement on the positioning precision of the hole is high, when the positioning pin is used for positioning, on one hand, the diameter of the pin is large, the positioning is inconvenient, on the other hand, the pin is a fixed diameter, the tolerance of the hole diameter of a part is large, and the part cannot be matched with the positioning of parts in different.
Disclosure of Invention
The invention aims to solve the technical problem of providing an adjustable movable hole positioner, wherein the adjustable hole positioner is arranged on a tool main body through a bottom plate and is used for accurately positioning a part with a hole with a larger diameter.
In order to solve the above problems, the specific technical scheme of the invention is as follows: an adjustable movable hole positioner comprises a bottom plate, a pressing device and a positioning device, wherein the pressing device is fixedly connected to the upper end face of a base, and the pressing device is in contact connection with the positioning device.
The bottom plate is of a fork-shaped structure, a plurality of positioning plates extend out of the center of the bottom plate, and a positioning seat is fixedly connected to the upper end face of each positioning plate.
The pressing device is of a forked structure, a plurality of pressing plates extend out of one center, the pressing plates correspond to the positioning plates in position, a screw rod is connected to the center of the pressing device in a penetrating mode, the lower end of the screw rod is fixedly connected with the bottom plate, a spring is sleeved on the outer circumference of the screw rod, the fixing spring is located below the pressing plates, a handle is sleeved on the outer circumference of the screw rod and located above the pressing plates, and wedge blocks are fixedly connected to the working end portions of the pressing plates. The pressing device is provided with a connecting rod with threads, the connecting plate is moved by the rotation of the handle on the connecting rod, and the positioning device is moved in place by the movement of the connecting plate.
The positioning device is as follows: the lower part of the connecting plate is fixedly connected with the positioning seat, one side of the upper part is clamped with an arc positioning block, the opposite side is an inclined plane, the slope is the same as that of the inclined plane of the wedge block, and the two inclined planes are in contact.
The positioning seat is connected with the connecting plate through a rotating pin.
The invention has the following beneficial effects: 1. realize the accurate positioning of the hole site with the part of the bigger hole
2. The positioner is light in form and efficient to operate.
