Abstract

The utility model discloses an inner hole positioning device, which comprises a cylinder inner hole, wherein a wedge block is arranged in the cylinder inner hole in a sliding manner, the wedge block comprises a first wedge-shaped ramp and a plurality of second wedge-shaped ramps which are integrally arranged, the second wedge-shaped ramps are fixed on the first wedge-shaped ramps, the interiors of the first wedge-shaped ramps and the second wedge-shaped ramps are fixed in the cylinder inner hole through a plurality of positioning studs, the device adopts a wedge block to slide, automatically positions and fastens an inner hole of the cylinder barrel, a left end nut is locked, so that the tool and the cylinder barrel are integrated, thus, the end face processing of the cylinder barrel can realize the positioning without adding a process frame nest, the installation and the operation of parts are simple and convenient, the device has low manufacturing cost, does not need special positioning procedure processing compared with the large cap tip tool applied in the same way in the market, greatly reduces the processing difficulty, meanwhile, the weight of the large cap center tool is too heavy, the load on the weight of a lathe supporting part is large, and the tool is light.

Description

Inner hole positioning device

Technical Field

The utility model relates to the technical field of positioning devices, in particular to an inner hole positioning device.

Background

Usually, when a flat end face or a special-form welding groove is processed, a frame nest needs to be turned nearby a cylinder barrel for positioning a lathe center frame, turning is very deep under the condition of needing certain precision, so that the material strength of the cylinder barrel is influenced to a certain extent, and the weight of a positioning part manufactured by a large cap tip similar to a tool is too heavy and is not practical for middle and small cylinder barrels.

SUMMERY OF THE UTILITY MODEL

The present invention is directed to an inner hole positioning device to solve the above problems.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides an inner hole positioner, includes the cylinder hole, the inside slidable mounting of cylinder hole has the wedge, the wedge includes first wedge ramp and a plurality of second wedge ramp of three integrative installation, second wedge ramp is fixed on first wedge ramp, first wedge ramp and second wedge ramp are inside to be fixed inside the cylinder hole through a plurality of locating stud.

Furthermore, still be fixed with a fixed section of thick bamboo on the cylinder hole, the screw rod is worn to be equipped with inside the first wedge ramp of a fixed section of thick bamboo and three integrative installation, the one end threaded connection that the screw rod stretches into is in cylinder hole inner wall, the nut is installed to the one end screw thread that the screw rod exposes.

Furthermore, the outer part of the inner hole of the cylinder barrel is provided with an observation hole.

Compared with the prior art, the utility model has the beneficial effects that:

1. the device adopts the wedge block to slide, automatically positions and fastens the inner hole of the cylinder barrel, extends into the wedge block for fixing through a plurality of positioning studs, and then locks the left end nut to integrate the tool and the cylinder barrel, so that the end surface processing of the cylinder barrel can realize the positioning without increasing the technological frame nest, and the part installation operation is simple and convenient;

2. compared with a large cap center tool applied in the same market, the large cap center tool has the advantages that the manufacturing cost is low, the special positioning process is not needed for processing, the processing difficulty is greatly reduced, meanwhile, the weight of the large cap center tool is too heavy, the weight burden of a lathe supporting part is large, and the tool is light;

3. the device is easy to realize due to low manufacturing difficulty, can finish quick positioning by the wedge block, and does not need a high-precision process.

FIG. 1 is a schematic view of the internal structure of the present invention;

FIG. 2 is a side view of the wedge block mounting structure of the present invention;

fig. 3 is a schematic view of the outer structure of the inner bore of the cylinder barrel of the present invention.

In the reference symbols: 1. an inner hole of the cylinder barrel; 2. a wedge block; 3. a first wedge ramp; 4. a second wedge ramp; 5. positioning the stud; 6. a fixed cylinder; 7. a screw; 8. a nut; 9. and (6) observing holes.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. In which like parts are designated by like reference numerals. It should be noted that as used in the following description, the terms "front," "back," "left," "right," "upper," and "lower" refer to directions in the drawings, and the terms "bottom" and "top," "inner," and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a hole positioner includes

cylinder hole

1, and 1 inside slidable mounting in cylinder hole has wedge 2, and wedge 2 includes first wedge ramp 3 and a plurality of second wedge ramp 4 of three integrative installation, and second wedge ramp 4 is fixed on first wedge ramp 3, and first wedge ramp 3 and second wedge ramp 4 are inside to be fixed inside 1 of cylinder hole through a plurality of locating stud 5.

Still be fixed with solid fixed cylinder 6 on the cylinder hole 1, solid fixed cylinder 6 and the inside screw rod 7 of wearing to be equipped with of the first wedge ramp 3 of three integrative installation, the one end threaded connection that screw rod 7 stretched into in 1 inner wall of cylinder hole, nut 8 is installed to the one end screw thread that screw rod 7 exposes, through lock nut 8 for frock and cylinder become an organic whole.

The outside of the cylinder barrel inner hole 1 is provided with an observation hole 9 for observing the inside condition of the cylinder barrel inner hole 1.

The working principle is as follows: the device adopts wedge block 2 to slide automatic positioning fastening cylinder hole 1, stretch into wedge block 2 inside through a plurality of positioning stud 5 and fix, then lock left end nut 8, make frock and cylinder become an organic whole, cylinder facing (operation) can realize not increasing technology frame nest location like this, parts installation is easy and simple to handle, this kind of device manufacturing cost is very low, the top frock of big cap that the same kind was used does not need special location process to process on the relative ratio market, the processing degree of difficulty greatly reduced, the top frock weight of big cap is also too heavy simultaneously and is big for lathe support part weight burden and this frock weight is very light, this kind of device makes the low very easy realization of the degree of difficulty, it both can to have wedge block 2 to accomplish quick location, do not need the very high process of special precision.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
